The objective of this paper is to ascertain the existence and uniqueness of common fixed point for four self mappings in intuitionistic Menger metric spaces under some conditions extending to (CLR) property and C-class functions. Some illustrative examples are furnished, which demonstrate the validity of the hypotheses. As an application to our main result, we derive a common fixed point theorem for four self-mappings in metric space. Our results generalize several works, including [4], [20].

The purpose of this research is to verify whether presentation order has an effect on the evaluation of products. In the empirical study, three types of humidifier and those of toaster were used. These products have 6 different sets of combination (3! = 3${\times}$2${\times}$1), and each set was evaluated by 15 subjects who were provided with two sets of images from humidifier and toaster in empirical study (N=90). Subjects completed measures assessing the five aspects: attractiveness, convenience, hygiene, efficiency and durability of the product. Each of the dependent measures was assessed on Likert-scale ranging 1 to 7. The ratings to the five aspects were added individually. Three types of humidifier and those of toaster were divided into 3 classes in terms of 'class A' which consists of the highest rated product, 'class C' which consists of the lowest rated product, and 'class B' which consists of the rest. Two main findings were discovered: First, the presentation order of both class A and class C influences the product evaluation whereas that of class B does not. As class A was presented as the last one, the subjects evaluated it the most positive. In the case of class C, on the contrary, when it is presented as the first is the best for itself; Secondly, the result shows that presented C-B-A sequence combination has a greater effect on entire evaluation than all other conditions in this study.

In this paper, we propose a method of class library repository design for provide reuser the object-oriented C++ class component. To class library design, we started by studying the characteristics of a reusable component. We formally defined the reusable component model using an entity relationship model. This formal definition has been directly used as the database schema for storing the reusable component in a repository. The reusable class library may be considered a knowledge base for software reuse. Thus, we used that Enumerative classification of breakdown of knowledge based. And another used classification is clustering of based on class similarity. The class similarity composes member function similarity and member data similarity. Finally, we have designed class library for hierarchical inheritance mechanism of object-oriented concept Generalization, Specialization and Aggregation.

Objective: Graves' disease encompasses hyperthyroidism and diffused goiter associated with auto-antibodies to the thyroid stimulating hormone(TSH) receptors. In clinical environment, treatments of Graves' disease have many side effects such as recurrence and hypothyroidism. We've studied the effects of Sipyukmiyukieum on DNA synthesis, cAMP synthesis, and MHC-class II expression of FRTL-5 thyroid cells were studied. Methods: DNA synthesis was investigated by using BrdU staining and cAMP synthesis by ELISA kit, and expression of $interferon-{\gamma}$ activated MHC class II by Flow cytometer. Results: After introduction of Sipyukmiyukieum, significant inhibition of DNA synthesis. cAMP synthesis, and expression of $interferon-{\gamma}$ activated MHC class II of FRTL-5 thyroid cells was observed. Conclusions: Judging from these results, Sipyukmiyukieum has potential as a potent herbal treatment for inhibiting the enlargement of goiter, synthesis of abnormal thyroidal hormones, and autoimmuine responses of Graves' disease.

The standard Java class library does not support the platform-dependent features needed by the application. Therefore, the Java application including the platform -dependent features must supplement the required features by invoking native functions using JNI. The native language programmer has to explicitly specify how to connect to various Java objects and later to disconnect from them. In this paper, I suggest a way to avoid these annoying works. The native method in the pure java class can not contain a native code block. By providing a native code block for the native method, it is possible for programmer to write a native code without being aware of JNI. To achieve this, I introduced the native class that is a java class on the native environment, and made it possible to interchange data by placing an arbitrator between the java class and the native class.

A class-E CMOS RF(Radio frequency) power amplifier with a 1.8 Volt power supply is designed using $0.25{\mu}m$ standard CMOS technology. To drive the class-E power amplifier, a Class-F RF power amplifier is used and the reliability characteristics are studied with a class-E load network. After one year of operating the power amplifier with an RF choke, the PAE(Power Added Efficiency) decreases from 60% to 47% and the output power decreases 29%. However, when a finite DC-feed inductor is used with the load, the PAE decreases from 60% to 53% and the output power decreases only 19%. The simulated results demonstrate that the class-E power amplifier with a finite DC-feed inductor exhibits superior reliability characteristics.

In [7) Scott has defined C-formation radical for a class C of near rings and has studied its porperties under chain conditions. A natural question that arises is: Does there exist a Lower C-Formation radical class L(M) containing a given class M of ideals of near rings in C? In this paper we answer this by giving. two constructions for L(M) and prove that prime radical is hereditary.

This thesis examines the origin, the change and the symbolic meanings of class representation, and offers a comparative study on the differences of class representation in the history of Korean and western costume on the basis of class representation methods and types shown from ancient times to 18C. In both eastern and western costume, the differences in status are commonly represented in the width and length of costume, color, textile, ornamental design, wearing, decoration, etc. The costume of noble class was wide and long, while that of common class was narrow and short so that it could be convenient for them to move around. Especially, from 16C to 18C in the west the costume of noble class was expanded to the extent that it was inconvenient for them to move around not only by skirt swelling by using hoop, but also by pad, ruff, lace, etc. This appears to show that they are not working class. Wearing and decoration of noble class were much more colorful, complicated and varied, while those of common class were simple and plain. In the west, the wearing of chiton and toga in Greece and Rome was different depending on social status. More specific look at the differences in class representation shown in the eastern and western costume reveals that the higher the rank, the more the women in both Gothic and Chosun period covered the body, thereby representing rank. In 18C, the women in both Rococo and Chosun period commonly showed excessive decoration and lavishness on their hair, and in this period the width of skirt was also commonly expanded to the longest extent, with a slight difference put aside.

In object-oriented software development, reuse has been studied for the enhancement of software quality and software developer's productivity. But improper modeling in design phase and uncontrolled change during maintenance activities have a problem to reuse a class. In this paper we analyze a semantic cohesion of classes using C++ Program dependency graph, and slice a class with cohesion, so that this method supports the re-estimate of class quality and the extensibility of class. Therefore this proposed method in this paper increases the easibility of the restructuring in the reusable systems, when the developer selects a requested component for a object-oriented program development.

Automation tools for program analysis are needed in order to program understand and maintain, extract the characteristics of object-oriented program such as class name, member function and data member. In this paper, we carried out design and implementation of the automation tool for effective maintenance of object-oriented software. Being based on Reverse Engineering, this approach extracts class relationship information from C++ source code and generates object-oriented model of class diagram using UML as the standard object-oriented methodology. Therefore, this paper provides developers visualized including class information, definitions of classes, inheritance relationships, set relationships, and simple reference relationships. Finally in this paper, we propose a method that construct class relationship information to table in analysis state and make form of table construction to link form so tat developers can perform understanding and maintaining program efficiently. And this method enable to restructure and reuse in object-oriented model.
