We often feel the necessity to communicate with members involved in a project to remote discuss business activities, needs for the fast file transfer, and check the existence of members to talk with. There are some commercial applications in these problems. However, in addition to those existing functions, this study focuses especially on adding couple of functions such as automatic responding function, in which a sender of a message automatically knows if a receiver checks the message. Its application is that a project leader sends an important message and later on can check at his desk the fact that who have checked their messages. The prototype application, build in this study, will check the correctness of every sub-function, and then the interface of inter-sub-functions, finally the integrity of the entire system, so that important information will not be lost among members of a project in the real world situation.

In this paper, we obtain two general laws of precise asymptotics for sums of i.i.d random variables, which contain general weighted functions and boundary functions and also clearly show the relationship between the weighted functions and the boundary functions. As corollaries, we obtain Theorem 2 of Gut and Spataru [A. Gut and A. Sp$\check{a}$taru, Precise asymptotics in the law of the iterated logarithm, Ann. Probab. 28 (2000), no. 4, 1870-1883] and Theorem 3 of Gut and Sp$\check{a}$taru [A. Gut and A. Sp$\check{a}$taru, Precise asymptotics in the Baum-Katz and Davids laws of large numbers, J. Math. Anal. Appl. 248 (2000), 233-246].

In this paper, an asynchronous nonvolatile memory module using a self-diagnosis function was designed. For the system to work, a lot of data must be input/output, and memory that can be stored is required. The volatile memory is fast, but data is erased without power, and the nonvolatile memory is slow, but data can be stored semi-permanently without power. The non-volatile static random-access memory is designed to solve these memory problems. However, the non-volatile static random-access memory is weak external noise or electrical shock, data can be some error. To solve these data errors, self-diagnosis algorithms were applied to non-volatile static random-access memory using error correction code, cyclic redundancy check 32 and data check sum to increase the reliability and accuracy of data retention. In addition, the possibility of application to an asynchronous non-volatile storage system requiring reliability was suggested.

Checklist method is rapid and comprehensive to evaluate in practice. Check items are commonly rated by subjective utility function; i.e., evaluator's significant judgment. Since human judgment includes fuzziness (vagueness) inherently in spite of its significance, fuzzy set theory is useful in this case. The paper illustrates a evaluation method using fuzzy checklist where check items are rated as fuzzy numbers. Pairwise comparison data is used to determine the weights of check items, since it has comparative advantage for human's fuzzy judgment. Sample of BASIC program is provided for microcomputer. When uncertainty is due to subjectivity or imprecision of data, this method can be applied to practical problems widely.

In spite of its simple design, structure and operating mechanism, swing check valves are one of the critical components which adversely affect the safety of the nuclear power plants if they fail to function properly. Therefore, it is important to evaluate the performance condition of the swing check valves in safety-related systems. The performance characteristics of swing check valves include opening characteristics, the minimum required flow velocity, the pressure drop at design flow, the disc stability, and the effect of the upstream disturbances. Among factors to identify the performance of a swing check valve, a method to evaluate the opening characteristics and the minimum required flow velocity, which guarantees to fully open the disc and hold the disc without motion, are presented to determine the operating region of the swing check valve, such as stable, tapping, or oscillation. Based on the determined operating region and opening characteristics, the simple methods of wear and fatigue analyses of the specific parts of the valve are also described.

The purpose of this study is examining a circulation and conflict of concepts and logics of the $Chos{\check{o}}n$-ness by analysing the $Chos{\check{o}}n$ national character and $Chos{\check{o}}n$ aesthetic consciousness. As entering the modern period, we understood the nations as a unit of the artistic awareness. So, national art is defined as a national character expression from this period. The $Chos{\check{o}}n$ aesthetic consciousness by raising in this period, which is connected with the discourse of national character, carry out a discussional practice defining the Korean originality. However, there is a circulation and conflict of concepts and logics about the $Chos{\check{o}}n$ aesthetic consciousness in the process of a discussion. For the most representative examples are 'the white-clad folk' and 'the beauty of sorrow'. An Hwak and Yanagi Muneyoshi are representative debaters who try to establish the $Chos{\check{o}}n$-ness and their discussion supports these facts. As An Hwak regressing of the respect for high antiquity, he demolished the historical character from the $Chos{\check{o}}n$-ness and overlooked aesthetic differences by a periodical change. Yanagi Muneyoshi totally separates arts from politics and disposes of Korean arts in an abstract timeless-space. The function of such an early-modern period's discourse about $Chos{\check{o}}n$ aesthetic consciousness is that $Chos{\check{o}}n$ national character makes the dehistoricization and depoliticization.

Recent building structures are superior in its ability but they are light and flexible, and so have problems of vibration. In general, the problem of vertical vibration is not considered in structural design. However, in terms of serviceability for inhabitants in buildings, the estimation of vibration in design stage is important. Characteristics of vertical vibration is changed by modeling method of beam-column joint. To check the characteristics of vertical vibration, many tests and analyses were conducted on constructing building in Seoul. Results of tests and analyses were compared using transfer function. As a results, to check the vertical vibration, the cramp ratio of beam-column joint must be considered and reduced in structural design.

Tongmu I Je-ma(1837-1900) set up Sasang Constitutional Medicine(四象體質醫學), a medical theory that would be original in the Korean medical history through his book ${\ll}$Tang-uisusebowon(東醫壽世保元)${\gg}$. In this book, he writes that he found the clue to his sasang Constitution(四象體質) theory from ${\ll}$Hwangjenaegyong(黃帝內經)${\gg}$. But the main logic that gives shape to the Constitution(體質) theory is $s{\check{o}}ng-ch{\check{o}}ng$ theory(性情論) of Confucian. Therefore, Tongmu(東武)'s Constitution $s{\check{o}}ng-ch{\check{o}}ng$ theory(體質性情論) is fundamentally based on confucian thoughts. Kongmaeng(孔孟) saw $s{\check{o}}ng$(性) as a base for connecting the entire mankind to be united, and $ch{\check{o}}ng$(情) as a individual thing that can exalted differently according to one's state of mind. Chuja(朱子) weakene the human's active volition by dividing $s{\check{o}}ng$ and $ch{\check{o}}ng$ as ibal(理發) and kibal(氣發) and therefore describing mankind to be submitted to Heaven's will. On the other hand Yolgok(栗谷) generalized $s{\check{o}}ng-ch{\check{o}}ng$ in the active mind of man himself by saying that $s{\check{o}}ng$ is when i-ki(理氣) does not act as a bodily function of the mind and $ch{\check{o}}ng$ is when it does. Furthennore he emphasized man's activeness on pursuing good by saying that the division of good and bad does not start from the origin of motion but is divided by the condition of ki(氣) which leads motion. Tongmu, who was influenced by Yulgok linked both $s{\check{o}}ng$and $ch{\check{o}}ng$ through, happiness, anger, sadness, pleasure(喜怒哀樂), and saw $s{\check{o}}ng$ as the ability to recognize good which is in the kijil(氣質) formed from the integration of i-ki, and saw $ch{\check{o}}ng$ as $s{\check{o}}ng$ blurred by man's greed. In addition to this, he says that the direct connection between each person's divergence in $s{\check{o}}ng-ch{\check{o}}ng$ and the condition of Four-organ(四臟) which is ki, not the mind which is i(理) forms sasangch'ejirin(四象體質人). His theory that illness comes from the partiality of $s{\check{o}}ng-ch{\check{o}}ng$ and therefore can prevent this by clarifying the mind and adjusting $s{\check{o}}ng-ch{\check{o}}ng$ through volition, has led Korean oriental medicine to be human based.

This study is an analysis the function Analysis Patterns for the effective application of VE(Value Engineering) and a presentation of the function analysis methods. 1. The function analysis of VE activities can be summarized 6 patterns as follows ; a generated ideas without function analysis process, a function analysis make use of inspection tools for generated idea, an illogical jump as a using of subjective terms, a using of duplication terms for same functions, a subjective ranking as function definitions for function analysis, and a large classification for a for approaching function definition. 2. In order for the effective function analysis, the process requires as follows; a check level by project advanced, a reclassified main nouns in the order of frequency of use, a main check objects by concepts of importance and satisfaction degree. It is not only good for the effective function analysis, it also induces effective turn out of the FAST Diagram for function arrangement.
