Description

Apparatus and method for providing recommended menu information for pregnant women}

The present invention relates to an apparatus and method for recommending a diet to a pregnant woman, and more particularly, to an apparatus and method for recommending a diet in consideration of the content of nutrients supplied to the pregnant woman.

In the age of aging, the problem of low birth rate began to emerge as a social problem. According to this trend, various support policies for pregnant women and policies for social consideration are being implemented.

However, these support measures can only be applied uniformly, and it is difficult to see that they are personal support measures in terms of actual dietary habits and health management of pregnant women.

In particular, there is no health food or nutritional guidelines for ingested food for pregnant women, so a system is needed to support both the health of the fetus and the health of the pregnant woman.

As the perception shifted toward maintaining health in everyday life, rather than health management conducted only in hospitals that check and manage the health of pregnant women, they began to pay great attention to the diet that is most closely related to this. However, while the recognition that diet is important is quickly established, the information is very poor.

It is very difficult for non-professionals to directly plan a healthy diet that suits them with general information from the Internet or books. Recently, in order to solve these problems, research on a method of recommending a diet that can help with eating habits by utilizing various recommendation techniques is actively being conducted.

Korean Patent Application No. 10-2014-0139800 (Method and Device for Providing Recommended Dietary Information) is not limited to pregnant women, but relates to a device that collects dietary information suitable for them and provides the collected information to general users.

However, the provision of external restaurant information is a problem that is difficult to apply to pregnant women with a large amount of movement, and it is a technology that searches for a restaurant suitable for the user based on the user's meal information, dietary information, and location information, and provides a suitable meal. There is a problem in that a diet that considers information on nutrient content information and calories according to the diet to be provided to pregnant women is not provided.

It creates a nutritional component table, a user intake status table that records the calories and nutrients content of the diet that the pregnant woman has finished eating, and a symptom-specific nutrient table that records the relationship between symptoms, diseases and nutrients of the pregnant woman.

The user record table includes at least one or more information selected from the group consisting of information input from the pregnant woman, such as pregnancy year, pregnancy week, age, pregnancy disease, pregnancy symptoms, supplement intake status, and nutrient information of the supplement.

3 is a diagram illustrating an example of a user record table according to an embodiment of the present invention.

The gestational weeks entered in the user record table change over time. The gestational week entered in the user record table is calculated as the current gestational week, but the time when the user inputs the gestational week and the gestational week entered at that time are required.

The current pregnancy week can be calculated by calculating the difference between the date at which the user inputs the pregnancy week and the current time, and adding the time difference to the pregnancy week input by the user.

For example, if the user inputs the pregnancy week as "4 weeks 1 day" in 2016/03/01, the current pregnancy week is "4 weeks 5 days" by adding "4 days" which is the time difference in 2016/03/05. Is calculated as

The number of weeks of pregnancy can be used as a standard for exposure of content provided by week, such as specialized information, and can be used to derive the stage of pregnancy.

The dietary evaluation of food recommendations and preparation can be made based on the stage of pregnancy progression (early/middle/late) derived from the gestational week, not the gestational week.

In other words, the gestational progression stage from the gestational weeks can be classified into 0 to 13 weeks for the first period, 14 to 27 weeks for the mid-term, and 28 to 40 weeks for the late period.

In addition, the age category classification-related matter included in the user record table may classify the age of a pregnant woman into two categories using the birth year, but is not limited thereto.

For example, it can be used as standard data to provide information such as various specialized information and diet by classifying under 30 years old and over 30 years old.

The user record table may be assigned an ID (my child ID) to distinguish the pregnant woman, and the presence or absence of diseases and symptoms of the pregnant woman is divided into 0 and 1 and reflected. In addition, the content of nutrients (per unit tablet) contained in supplements that pregnant women are taking can be described.

The user record table can be used by freely processing the table or removing some fields according to the intended use.

The upper limit intake table contains information on the upper limit intake of nutrients that a pregnant woman should consume.

4 is a view showing an example of the upper limit intake table according to an embodiment of the present invention.

As shown in Figure 4, the upper limit intake table is divided into under 30 years old and over 30 years old according to the age category, and the pregnancy progression stage is divided into the first half, middle, and late stages, and the intake of the upper limit nutrients required for each category is recorded. .

5 is a view showing an example of a recommended sufficient intake table according to an embodiment of the present invention.

As shown in Figure 5, the recommended sufficient intake table is divided into under 30 years old and over 30 years old according to the age category, and the stages of pregnancy progression are divided into the first half, middle, and late periods to provide sufficient intake of recommended nutrients required for each category. Record it.

The upper limit intake table and the recommended sufficient intake table shown in FIGS. 4 and 5 may also be utilized by removing some fields as necessary.

In addition, the upper and lower energy limits shown in FIGS. 4 and 5 mean the upper and lower limits of the amount of heat per day.

The food nutrition table records the calorie content and nutrient content of food.

6 is a view showing an example of a food nutritional component table according to an embodiment of the present invention.

As shown in FIG. 6, after classifying food into food groups and specifying food names belonging to each food group, the food nutritional component table records nutrients and calories contained in the food per unit gram (g).

The user intake status table records the nutrient content and calories contained according to the diet consumed by the user in the number of units (one meal).

7 is a view showing an example of a user intake status table according to an embodiment of the present invention.

As shown in FIG. 7, the pregnant woman is identified by ID, and the content of nutrients and calories contained according to the food consumed by each pregnant woman are recorded. This can be calculated and derived by the above-described food and nutritional component table, and is recorded so that information on the type, content, calories, etc. of the nutrients actually consumed by the pregnant woman can be checked according to the one-time diet. The intake date and time may be classified into morning/lunch/dinner/morning snack/afternoon snack/dinner snack, etc., but is not limited thereto.

In addition, the user intake status table may be created by referring to information on the supplement intake amount in the user record table so that the type, content, and calories of nutrients can be reflected by the supplements consumed by the pregnant woman.

The Nutrient Needed by Symptom Table is a table that records the relationship between symptoms and diseases of pregnant women and nutrients.

8 is a diagram showing an example of a nutrient table for symptomatic diseases according to an embodiment of the present invention.

As illustrated in FIG. 8, a case corresponding to a necessary nutrient according to a disease such as neural tube disorder, depression, gestational diabetes, etc. in a pregnant woman may be indicated as 1, and a case not corresponding to a necessary nutrient may be indicated as 0. In addition, necessary nutrients according to vomiting, leg cramps, constipation, swelling, anemia, etc. classified as symptoms of a pregnant woman may also be marked as 1 and 0 as described above.

The table storage unit 200 stores the generated tables as shown in FIGS. 3 to 8 described above.

The filter unit 300 filters foods exceeding the upper limit of nutrient intake by the pregnant woman by using the information recorded in the upper limit intake table, the user intake status table, and the food nutritional component table.

The filter unit 300 loads the upper limit intake table, the user intake status table, and the food nutritional component table stored in the table storage. You can also load a reduced table with unnecessary fields removed, leaving the required fields in each table.

The upper limit intake table called is a table to be used according to the age category of the pregnant woman and the stage of pregnancy progression.

The filter unit calculates the allowable intake amount that the user can consume as a single meal.

If there is information on the intake of the first two meals (previous two meals) of the pregnant woman according to the user's intake status table, each nutrient can be consumed by calculating the "maximum daily nutrient intake-nutrient intake included in the previous two meals" Find the amount.

If the calculation result is negative, it can be expressed as a value of 0.

If the daily supplement intake information is entered, for each nutrient, calculate the amount that can be ingested by making "upper day-based nutrient intake-nutrient intake included in the previous two meals-(daily supplement intake) × 2/3".

If there is no information about the user's previous two meals intake, calculate "(upper day limit nutrient intake × 1/3)" for each nutrient to find the amount that can be consumed by nutrient. At this time, if the daily supplement intake information is entered, for each nutrient, "(upper day standard nutrient intake × 1/3)-(daily supplement intake amount) × 1/3" to obtain the available amount.

The filter unit 300 compares the field value of the food nutritional component table with the allowable intake capacity, and performs filtering to remove foods having a field value exceeding the allowable intake from the recommendation consideration target.

The insufficient intake amount calculation unit 400 loads the recommended intake amount table and the user intake status table from the table storage unit. The called recommended intake table may be a table containing only records to be used according to the age category of the pregnant woman and the stage of pregnancy progression.

Insufficient intake amount calculation unit 400 calculates the amount of intake available for each nutrient by calculating "recommended nutrient intake range for each nutrient-the nutrient intake included in the previous two meals" for each nutrient when there is information about the user's intake of two meals.

If the calculation result is negative, it can be expressed as a value of 0.

If the daily supplement intake information is entered, for each nutrient, "Recommended nutrient intake per day-Nutrient intake included in the previous two meals-(Supplement intake per day) × 2/3" Seek.

In addition, if there is no information on the user's previous two meals intake, the amount of available intake for each nutrient is calculated by calculating "(recommended sufficient intake of nutrients per day x 1/3)" for each nutrient.

At this time, if the daily supplement intake information is entered, for each nutrient, "(Recommended nutrient adequate intake range × 1/3)-(daily supplement intake) × 1/3" to obtain the amount that can be consumed.

The food ranking and grouping unit 500 uses the nutrient intake deficit information calculated by the intake deficit calculation unit 400 to obtain all the nutrients containing the intake deficit amount fulfillment rate for each nutrient, and satisfy the intake deficit amount for each nutrient. Calculate the average value of the ratio and group each food according to the average value.

The rate of satisfying the insufficient intake amount for each nutrient can be calculated by Equation 1 below.

[Equation 1]

P = min(AS, AC)/AR

Here, P is the rate of fulfillment of insufficient intake, AS is the insufficient amount of nutrient intake, AC is the nutrient content, and AR is the recommended amount of nutrient intake once.

For example, suppose that the recommended protein intake of preterm pregnant women is 50g, the bean sprouts Haejangguk contains 3.43g of protein, and the insufficient intake is 20g, the rate of fulfillment of insufficient intake calculated by Equation 1 above is min(20, 3.43)/50=0.0686.

According to Equation 1 above, the rate of satisfaction of insufficient intake amount for all nutrients is calculated, and the average of the rate of satisfaction of insufficient intake amount for each food is calculated.

For example, as in the previous example, the rate of satisfying the insufficient intake of each nutrient in the bean sprouts Haejangguk is protein = 0.0686, dietary fiber = 0.5, moisture = 0.6, vitamin C = 1,… If it is, calculate the average of the rate of fulfillment of insufficient intake by dividing (0.686+0.5+0.6+1+...) by the number of nutrients.

The food ranking and grouping unit 500 sorts and groups the average of the rate of satisfaction of the insufficient intake amount calculated for each individual food in descending order.

Grouping methods can be considered in various ways. As a grouping method according to an embodiment of the present invention, after sorting, food may be divided into 11 equal parts and divided into 11 groups.

The criterion for dividing a group into 11 equals is to set the average in units of 10 points, 0~9 points=>group 11, 10~19 points=>group 10, ........, 90~99 points=> Group 2, 90 to 99 points => Group 1 can be set, but is not limited thereto. The names of these groups are hereinafter referred to as deficient groups.

The food ranking selection unit 600 creates a symptomatic disease user nutrient dependence table in which the number of nutrients related to a user's symptom and disease is recorded using a user record table and a nutrient need table for each symptomatic disease, and the symptomatic disease user nutrient dependence table The symptomatic disease benefit table is created using the food and nutrition table.

The symptomatic disease user's nutrient dependence table (G) is calculated by Equation 2 below, and the symptomatic disease benefit table (L) may be calculated by Equation 3 below.

[Equation 2]

G = E .F ^T

Here, E denotes a user record table matrix, and F ^T denotes a transposition matrix (a matrix in which columns and rows are changed) of the necessary nutrient table matrix for each symptomatic disease.

[Equation 3]

L = G .K ^T

Here, K ^T is the transposed matrix (column and row-changed matrix) of the food and nutritional component table matrix.

For example, suppose that the user record table matrix E is derived as shown in Table 1 below, and the necessary nutrient table matrix F for each symptom and disease is presented as shown in Table 2 below.

Symptom 1 Symptom 2 Symptom 3 … Disease 1 Disease2 Disease3 … Disease 9 One 0 0 … One One 0 … One

Nutrient name Symptom 1 Symptom 2 Symptom 3 … Disease 1 Disease2 Disease3 … Disease 9 Nutrients 1 0 0 0 … One One 0 … One Nutrients 2 One 0 0 … 0 0 One … 0 Nutrients 3 0 0 0 … 0 One 0 … 0 : : : : : : : : : :

When Tables 1 and 2 are converted into matrices E and F, and Equation 2 described above is applied, the symptomatic disease user nutrient dependence table matrix G is derived, and Table 3 is derived accordingly.

Nutrients 1 Nutrients 2 Nutrients 3 Nutrients 4 Nutrients 5 Nutrients 6 Nutrients 7 … Nutrients 21 4 0 0 0 3 2 0 … 0

In addition, in order to derive the symptomatic disease benefit table L, the matrix G and the aforementioned food and nutritional component table (see FIG. 6) are substituted into Equation 3 to derive the symptomatic disease benefit table L.

It is assumed that the food nutritional component table matrix K is constructed in the form shown in Table 4 below.

group Food name Nutrients 1 Nutrients 2 Nutrients 3 Nutrients 4 … Nutrients 21 One Food 51 One 0.4 0.6 0.5 … 0.1 One Food23 0.3 One 0.7 0.8 … 0.5 One Food78 0.7 0.6 0.4 0.2 … 0.6 One Food24 - - - - … - 2 Food201 - - - - … - 2 Food142 - - - - … - 2 Food81 - - - - … - 3 Food203 - - - - … - : : : : : : : - 11 Food16 - - - - - -

By substituting the matrix G and the matrix K in Equation 3 above, the symptomatic disease benefit table L in the form shown in Table 5 below is derived.

Shortfall group One One One One 2 2 2 … 11 food Food24 Food23 Food 51 Food78 Food81 Food201 Food142 … Food16 Symptom

Benefit 71 57 50 45 55 26 23 … 4

The food ranking selection unit 600 sorts the foods calculated by the symptomatic disease benefit table by ranking, and arranges the food rankings by the ranking of foods in the groups generated by the food ranking and grouping unit 500.

In addition, the food ranking selection unit 600 may rearrange the ranking of food in the group by reflecting the calorie content of food as shown in Table 6 below.

Shortfall group One One One One 2 2 2 … 11 Benefit group One One One 2 One One One … One food Food 51 Food23 Food24 Food78 Food142 Food81 Food201 … Food16 calorie 450 344 234 510 400 300 200 … ??

As shown in Table 5, foods in the deficiency group are arranged in order of symptomatic disease benefit. In the table above, there are Food 24, Food 23, Food 51, and Food 78 in deficiency group 1.

The symptomatic disease benefits of these foods are 71, 57, 50, and 45. Here, based on the benefit of symptomatic disease, the food in the deficiency group 1 is grouped again into 3 groups and divided into groups. This group is called the benefit group. Food 24, Food 23, and Food 51 belong to the benefit group 1.

Sort the foods in the benefit group in descending calorie order.

Let's say that the calories in Food 24, Food 23, Food 51, and Food 78 are 234Kcal, 344Kcal, 450Kcal, and 510Kcal, respectively. The foods in the benefit group are sorted in descending calorie order, resulting in food 51-food23-food24.

If Food 81 (300Kcal), Food 201 (200Kcal), and Food 142 (400Kcal) are arranged in the same way, the order is Food 142-Food 81-Food 201.

The step of creating the table (S100) is a step of creating a user record table, an upper limit intake table, a recommended intake amount table, a food nutritional component table, and a nutrient required for each symptom and disease table described above.

Each table has been described above.

In the storing of the table (S200), the created table is stored, a table that is newly added or needs to be modified is loaded and re-stored after correction.

In the step of filtering foods exceeding the upper limit of nutrient intake (S300), the amount of nutrients consumed by the pregnant woman so far is calculated through the user intake status table and the food nutrient content table, and compared with the upper limit intake table to exceed the upper limit intake. This is the step of removing food.

The step (S400) of calculating the nutrient intake deficit is calculated using the recommended intake amount table and the user intake status table.

In the step of sorting and grouping the food (S500), the food is grouped by calculating an intake insufficient amount fulfillment rate for each nutrient by the pregnant woman by Equation 1 described above, and calculating an average of the intake insufficient amount satisfaction rate for each nutrient.

10 is a detailed flowchart of a food ranking step according to an embodiment of the present invention.

As shown in FIG. 10, the food ranking step (S600) is a step of creating a symptomatic disease user nutrient dependence table in which the number of nutrients related to the user's symptoms and disease is recorded using the user record table and the nutrient required for each symptom disease S610) and generating the symptomatic disease benefit table using the nutrient dependence table and the food nutrition table (S620), and rearranging the ranking of food in the group by reflecting the calorie content of the food (S630). ).

The symptomatic disease user nutrient dependence table generation step (S610) is a step of creating a symptomatic disease user nutrient dependence table as shown in Equation 2 described above using the user record table and the necessary nutrient table for each symptomatic disease. The generating step (S620) is a step of generating a symptomatic disease benefit table by using a symptomatic disease benefit table and a food nutritional component table as shown in Equation 3.

In the step of rearranging the ranking of foods in the group by reflecting the calories contained in the food (S630), the order of diets to be recommended to pregnant women is arranged by realigning not only data related to symptomatic disease benefit, but also calories of food.

Hereinafter, a diet recommendation apparatus and method according to another embodiment of the present invention for determining whether to recommend a diet input by a pregnant woman will be described.

Description of the configuration redundant with the previous embodiment will be omitted.

11 is a functional block diagram of an apparatus for recommending a diet for pregnant women according to another embodiment of the present invention.

As shown in Figure 11, the diet recommendation device for pregnant women according to an embodiment of the present invention includes an upper limit intake table for recording the upper limit intake of nutrients, a recommended intake table for recording the recommended nutrient intake, and a food for recording calories and nutrient content of food. A table generation unit 1000 for generating a nutritional component table and a user intake status table for recording calories and nutrients content of a diet completed by the pregnant woman, a table storage unit 2000 for storing the generated tables, and the food nutritional component Using the table, calculate the calorie content and nutrient content of each food included in the diet entered by the pregnant woman, and use the user intake status table to determine whether the sum of calories contained in each food exceeds the upper limit calories or lower limit calories. And a diet suitability determination unit 3000 that determines whether it is insufficient, and determines whether the nutrient content of each food exceeds the nutrient upper limit intake amount, or whether the nutrient recommended intake amount is less than.

The table generation unit 1000 generates an upper limit intake amount table, a recommended intake amount table, a food nutritional component table, and a user intake status table.

The table storage unit 2000 stores tables generated by the table generation unit.

The diet suitability determination unit 3000 calculates the sum of the amount of calories contained (calories) and the content of each nutrient for one meal prepared by the user. In the food and nutritional table, the user enters the foods and calculates the sum of the calories and the content of each nutrient.

In addition, the diet suitability determination unit 3000 determines whether the sum of the calories contained is within the allowable intake range. Depending on the age category of the user and the stage of pregnancy, the upper limit intake record and the recommended sufficient intake record to be used are determined, and the calorie upper limit value corresponding to the user type (age category, pregnancy progression stage) is brought to the upper limit intake table, and the calorie content lower limit intake value Is taken from the recommended adequate intake table. If the sum of calories contained exceeds the upper limit intake or falls below the lower limit intake, it is judged as an inappropriate diet.

The diet suitability determination unit 3000 determines whether the sum of each nutrient content is within the allowable intake range. The upper limit value of each nutrient corresponding to the user type (age, stage of pregnancy progression) is imported into the upper limit intake table, and the lower limit intake value of each nutrient is taken from the recommended sufficient intake table.

Calculate the sum of the content of each nutrient contained in all foods in the diet, and if the information of some nutrients among the contained nutrients is marked as'N/A', the sum of the content is not calculated and the nutrient name is saved. In the diet evaluation result, it may be derived as'a list of nutrients that are difficult to evaluate because foods without content information are included.

The diet suitability determination unit 3000 determines that only nutrients for which the total can be calculated because there is content information for all foods in the diet, and if the total content of each nutrient exceeds the upper limit intake or falls below the lower limit intake, it is determined as an inappropriate diet. do.

12 is a flow chart of a method for recommending a diet for pregnant women according to another embodiment of the present invention.

As shown in Figure 12, the method of recommending a diet for pregnant women includes the step of receiving diet information of the pregnant woman (S1000), an upper limit intake table for recording the upper limit intake of nutrients, a recommended intake table for recording the recommended nutrient intake, and the calorie and nutrients contained in food. Generating a food nutrition table for recording the content and a user intake status table for recording calories and nutrient content of the diet that the pregnant woman has finished eating (S2000), storing the generated tables (S3000), the food nutrition Calculating the calorie content and nutrient content of each food included in the diet input by the pregnant woman using the ingredient table (S4000), the sum of the calories contained in each food using the user intake status table exceeds the upper limit caloric value Or determining whether or not it is less than the lower limit calorie (S5000), and determining whether the sum of the nutrient content of each food exceeds the upper limit of nutrient intake or less than the recommended nutrient intake (S6000).
