The purpose of this study is to investigate the need of home economics education on high School male students for purpose, the questions raised in this study are as follows. 1. Does home economics education on high school male students needs\ulcorner and are whether not or home economics education on high school male students need different according to sex, age, edu-cation, income, occupation\ulcorner 2. If home economics education on high school male students need or not. What is the reason of that\ulcorner and are the reason of that different according to sex, age, education, income, occupation\ulcorner 3. If home economics education on high school male students need, what is the contents of home economics education and are that different according to sex, age, education, income, occupation\ulcorner The subjects of the study consisted of 183 men and women in Ch’ong ju City(over 21 years old) The data were analiged by statistical procedures such as frequency, X(sup)2, oneway ANOVA, two-way ANOVA, Duncan’s Multiple Range Test. The major results of the study were summarized as follow: 1. The response rate on home economics education on high school male students was absolutely high(91.8%). of demographic variables, the only sex appeared the significant differences. the men groups responsed higher not to need than the women groups. 2. As the reasons of home economics educations on high School male students needing the respons of the highest response rate were that ‘as family community, family members understant, cooperated, and are responsible with each other or one anther’and that ‘as society becomes in-dustrial gradually, family members have to have the accurate perception, or attitudies on home life’of demographic variables, sex, income, and occupation appeard the significant differences. In the contrast of that, as the reaspon of home economics education on high school male stu-dents not needing, the reasons of the highest. response rate were that ‘as sex, the role is different’and that ‘home economics education needs not essentially to learn through the school education’. and there were not differences according to demographic variables. 3. As home economics education contents for high school mal students, the most need content part was child part. the second content part was family development and family relationships part. There was the significant differences according to all the demographic variables. Particulary, the lower the lever of education, in come and occupation were, the less the degree of need on all content part was.

In the study of differential equation the most obstacle is that you have to spend lots of times and the plots of solutions are not easy by hand. If we do not solve these kinds of problem, it is difficult to achieve the goal of the object which is the understanding and the practical use of the differential equation. In this paper we explain what should be Maple's usefulness in the method of removing these obstacles, and introduce the stepwise executing codes of Maple which is developed for student's easy application.

With the government's support for new and renewable energy, photovoltaic equipment has rapidly been supplied. However, compared to supply rate, maintenance has not supported enough and relevant research has not much conducted. Therefore, the purpose of this study is to analyze maintenance effectiveness of photovoltaic equipment. What is the most important in maintenance effectiveness is a rise in power generation. It was estimated that if photovoltaic equipment for detached houses is maintained well, power generation increases by 4.0% at least, and by 6.5% on average. As a result, it was analyzed that it is necessary to maximize the effectiveness of the government's budget investment through well maintenance of photovoltaic equipment for detached houses.

Professor Daihyun Chung has recently presented an intriguing view of Ban-mal(non-honorific expressions) in Korean. He criticizes uses of Ban-mal, on the grounds that they presuppose the existence of hierarchical structures in human beings. Professor Chung also advocates ″a relational theory of Ban-mal″ according to which ascriptions of 'n-mal' should be relativized to the speaker-hearer relationship. He employs this view in showing that uses of Ban-mal indeed presuppose the existence of hierarchical structures in human beings I claim that Professor Chung has not shown the credibility of his relational theory of Ban-mal, and that this very view leads to an unintended and undesirable consequence. Moreover, 1 show that even if we assume that this view is true for the sake of an argument, he is not able to show that uses of Ban-mal indeed presuppose the existence of hierarchical structures. All he can show is rather that uses of 'Ban-mal'(a meta-linguistic expression) presuppose the existence of hierarchical structures. Finally, 1 conclude that what really presupposes the existence of hierarchical structures is the asymmetrical uses of Ban-mal and honorific expressions.

The modem world has brought a wave of changes, not the least of which is globalization or what is often referred to as the "borderless society." In recent times, changes in the global business environment, such as trade deregulation and advances in technology, are challenging us to find new ways of thinking about and coping with these new forces. The field of global logistics has encountered a host of paradigm shifts as well. Therefore, it is critical that managers involved in international logistics take into account perceptional swift or at least understand the value of fully utilizing information. The appropriate management of human resources is a key factor in dealing with not only new information technology, but also shifts in the business environment. In particular, it will be important for Korea's logistics managers at international logistics companies to continually work to develop themselves, as they must carry out a critical role in global supply chain management. If they fail to take heed of the demand's of the new environment, the competitiveness of Korean enterprises in international logistics will suffer severely.

Earthquake had occurred in the Korean Peninsula about 2,100 times is not well known in the world. With the true liquefaction judgment is well used to in Korea. Through liquefaction judgements were compared with specifications between Korea and Japan, it would be offered some suggestions for liquefaction judgement used in Korea. The proposals were as 1) It can be known that what kind of earthquake will make unstable state between long-term and short-term earthquake if the natural period of ground turned out. In that case, Hachinohe and Ofunato Earthquake wave will need no more. 2) Liquefaction-induced lateral flow or damage for structure should be estimate but it had not performed in Korea. 3) Heavy rain and ocean wave-induced liquefaction also should be examined thoroughly in slope or ocean, respectively.

Indigenous energy resources available in Korea are limited to the three major resources such as Korean anthracite, hydraulic potential and wood and straws. As reported in various reports concerning energy problem in Korea, unfortunately these three major resources are not only poor in quality but also limited in quantity. The amount of energy to be imported, which will be increased at a considerably high rate by years due to the shortage in the supply by domertic sources against the demand, is studied in the view-pint of sound and logical energy dependence upon the external sources. What would occur, if the imported energy would be exclusively limited to an energy source only, has an enough reason to be paid a significant consideration. As a result, the feasibility is discarded in favour of nuclear power plants after an extensive prospect for electric power development plan covering more than coming thirty years, i.e., up to the year of 2,000 A.D. In briefing, this paper indicates that a measures to accomodate as large amount of nuclear power plants as possible in the electric power system is not only inevitable for a sound solution of the severe energy problem with which Korea is to be confronted but also leads to the national benefit.

In an earlier paper ('Scheduling Jobs on a Number of Identical Machines' by Elmaghraby and Park, March 1974, AIIE Transactions) a branch-and-bound algorithm was developed for the sequencing problem when all jobs are available to process at time zero and are independet (i.e., there are not a priori precedence relationships among jobs.). However, the amount of computation required by the algorithm was not considered to be short if more than 50 jobs were processed. As an effort to improve the algorithm, the present paper modifies the implicit enumeration procedure in the algorithm so that moderately large problems can be treated with what appears to be a short computational time. Mainly this paper is concerned with improving the lower bound in the implicit enumeration procedure. The computational experiences with this new branch-and-bound algorithm are given.

Daesoonjinlihoe and Buddhism have found the cause of grudge and agony in the human mind. Fundamentally human being suffers grudge and agony which man in it self makes unless he acquire what he wants. So if human being recognizes the cause of that, the cause would disappear. And there are certainly needed regulation of 'dosu' in Daesoonjinlihoe. That implies the limitation of human effort. The worlds of heaven, earth, human being have to stand up in the same time, and there would appear paradise. In that case human being and the world of divinities are able to be relieved. Compared to that, Buddhism does not admit other Power without human effort and cultivation on oneself. Epistemological awakening of the 'solution of grudge(haewon)' and mokṣa accompany the 'saving each other(sangsaeng)' and maitrī·karuṇā. 'Haewon' and 'sangsaeng' have causal relation, further more epistemological awakening of 'haewon' and practical virtue of 'sangsaeng' would not be detached.

Stealing the source code of a program is a serious problem not only in a moral sense but also in a legal sense. However, it is not clear whether the code of a program is copied from another or not. There was a program similarity checker detecting code-copy by comparing the syntax trees of programs. However this method has a limitation that it cannot detect the code-copy attacks when the attacker modifies the syntax of the program on purpose. We propose a program similarity check by program control graph, which reveals not only syntax information but also control dependancy. Our method can detect the code-copy attacks that do not change control dependancy Moreover, we define what code-copy means and establish the connection between code-copy and similarity of program control graph: we prove that two programs are related by copy congruence if and only if the program control graphs of these programs are equivalent. We implemented our method on a functional programming language, nML. The experimental results show us that the suggested method can detect code similarity that is not detected by the existing method.
