The use of all examples or exemplary terms, e.g., " etc., " in this disclosure is for the purpose of describing this disclosure in detail and is not intended to be limited by the scope of the claims, But is not limited thereto.

Also, unless stated to the contrary, such as " essential ", " importantly ", etc., the components described in this disclosure may not be essential components for the performance of this disclosure.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

It is to be understood that the present disclosure is not limited by the specific embodiments described in the specification and that various changes and modifications may be made therein without departing from the spirit and scope of the present disclosure, And substitutions are to be understood as being included in this disclosure. Therefore, the disclosed embodiments should be understood in an illustrative rather than a restrictive sense.

The scope of the present disclosure is defined by the appended claims rather than the detailed description of the invention, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present disclosure.

The terms " part, "" module, " and the like, as used herein, refer to a unit that processes at least one function or operation, and may be implemented in hardware or software or a combination of hardware and software.

"Module" may be embodied by a program stored on a storage medium that can be addressed and that may be executed by a processor.

For example, " part " or "module" may include components such as software components, object oriented software components, class components and task components, Microcode, circuitry, data, databases, data structures, tables, arrays, and variables, as will be appreciated by those skilled in the art.

As used herein, the description "A may include one of a1, a2 and a3" has a broad meaning that an exemplary element that may be included in the element A is a1, a2, or a3.

The element capable of constituting the element A due to the above description is not necessarily limited to a1, a2 or a3. It should be noted, therefore, that the element capable of configuring A is not exclusively interpreted in the sense that it excludes other elements not illustrated except a1, a2, and a3.

In addition, the above description means that A may include a1, include a2, or include a3. This does not mean that the elements of which A constitute A are necessarily determined within a given set. For example, it should be noted that the description does not necessarily construe that a1, a2, or a3 selected from the set including a1, a2, and a3 constitute component A.
