Research on information systems and software engineering has often neglected behavioral effects, which may play a role in decision making on software development. The current study addresses this issue by empirically investigating the behavioral roots of over-requirement in the context of a software development project via an experiment. The negative phenomenon of over-requirement refers to specifying a software system beyond the actual needs of the customer or the market, which overload the system with unneeded features. The research question addressed here is whether over-requirement is due in part to the emotional involvement of developers with the software features they developed because of behavioral effects. Previous studies have demonstrated that under the endowment, I-designed-it-myself, and IKEA effects, people become emotionally involved and overvalue physical items that they respectively possess, self-design, or self-create. The findings of our experiment show that participants over-valued features they were assigned to be responsible for, to specify, or to construct, thereby confirming that the three behavioral effects play a role in software development decisions and affect over-requirement. Thus, the study contributes to software development research and practice from the behavioral economics perspective, highlighting the roots of over-requirement.

This study intends to closely examine an evaluation of effectiveness of the HRM associated with interactions among employees(I), purpose recognition(P), role feedbacks(R), and motivative compensation(M). The following is a summary of the results of this research: From the study of the actual situation of the human resource management by the Korean firms, it appeared that the form of existence of vision systems possessed the form of having been written as documents and co-shared. And, although, in the area of motivation endowment and feedbacks, the level of motivation endowment regarding the comprising member by those in charge of departments and the level of reflection of the company's personnel policies in the execution of work by the departments were ordinary, the level of presenting the opinion of the departments regarding the company's personnel policies was shown to be low. And, the decisive elements of wages and the compensation standard were in the order of performance basis and long service. Also, it was analyzed that the leadership style of the CEO is the most important element that influences human resource management policies. And, it was analyzed that in the evaluation of the human resource management area the roles regarding evaluation and compensation, especially, the mutual interactions of the comprising members, feedbacks, and improvement activities are inadequate. And the managerial implications are discussed.

This study examines whether product promotions are influenced by the market standing of promoted products, using social comparison theory (upward versus downward comparisons). It is hypothesized that people in possession of a product that is inferior to the one on promotion express less discomfort about the promotion and use the information more than do people in possession of a superior product. People in possession of an inferior product may also exhibit more positive attitudes toward the product on promotion, but may show poorer attitudes toward their own possessed product than do people with a superior product. This is because people in an inferior socioeconomic position show a strong motivation to improve themselves through upward social comparison, whereas people in a superior socioeconomic position maintain a strong sense of superiority in downward social comparison, which suggests strong endowment effects. The findings mainly support the hypotheses, and suggest that sales promotions are more effective for people who currently own an inferior product, but not for people with a superior product, who have a strong motivation to maintain their sense of superiority. The findings also imply that, in order to attract consumers in the superior market, managers for inferior products need to turn to methods other than sales promotions, which may include introducing a new brand or sub-brand, or emphasizing luxury and modern features. In contrast, managers for superior products may emphasize product functions and attributes of superior products in their promotions, as people with inferior products may consider such information as benefits of the superior products.

The Taekwondo uniform has remained consistent since it was officially designed in a V-neck form in 1976. Taekwondo is a martial art that emphasizes social etiquette; therefore, it is necessary to dress in a uniform that reflects Korean traditions and ancient oriental philosophy. However, the current official uniform has limitations in endowing traditionality and many usability problems. Thus, recognizing the problems raised with the uniform, the Kukkiwon (World Taekwondo Headquarters) developed a new style official uniform in 2011. This study is to endow traditional meaning to a new style uniform and proposes some design modifications that can convey a more traditional adequacy. The development of the new official uniform began with a specific plan for change from the existing uniform, this study as subsequent work is significant in that its endowment of symbolism and modification proposal is for the actual execution and global dissemination of traditional Taekwondo culture. The results of this study are as follows. First, we can endow Korea's traditional historicity and symbolism to the new uniform in form and colors. All contents of the design (in which the front side is open, the top is adjusted rightward, the rear length is shorter than the front length, comfort provided by side vents, dual collars for children's uniforms, and a belt) are adapted from the Korean traditional costume. Consequently, historicity can be endowed to the uniform. It is also confirmed that the traditional oriental philosophy including heaven and earth (天地), Yin-Yang (陰陽), and Five Elements (五行) can be endowed in the use of colors. Second, in order to project deeper historicity and symbolism to the form of the new uniform, this study proposes design modifications based on the selection as an item of Simui (深衣), a type of traditional clothing that contains a high symbolism similar to the Taekwondo uniform. It proposes giving shape to the practice of manners, the righteous life, and the straightforward mind by modifying the design of the uniform in the fish belly part of the sleeves, collars, back stitches, and side seams.

본고는 경제적 최적화모형인 확률제약 계획모형법을 이용하여, 농업용수 부존량 감소에 따른 농업이윤의 감소분을 계측하고 이를 통해 농업용수의 경제적 가치를 분석하고자 한다. 이를 위해 국가 전체 농업자원배분을 최적화 모형으로 구축하고, 농업용수를 포함하는 자원부존제약조건과, 각 상품의 가격이 형성되는 시장조건, 국제무역 및 관련정책변수의 영향들을 반영하고, 용수의 경우 그 이용량이 연도별로 불안정할 수 있다는 것까지 반영한다. 농업용수감소량이 농업부문 이윤에 미치는 영향을 시나리오를 주어 분석하면, 농업용수의 톤당 경제적 가치는 $303{\sim}1,093$원/$m^3$의 분포를 가지는 것으로 나타난다. 동일한 양의 용수량이 줄어들더라도 용수의 공급이 불안정할수록 경제적 가치 손실이 크며, 아울러 많은 양의 용수손실이 발생할수록 경제적 손실이 커 용수감소의 한계피해는 용수감소량의 증가 함수인 것으로 파악된다.

The purpose of this paper is to perform empirical studies on the impact of pollution intensity on international competitiveness using 1993 and 1998 data, and to estimate the change in environmental regulation level faced by the firms during 1993~1998. Collecting relevant data and providing them for further studies in the area are another purposes of the paper. The first method is the regression of various indices of international competitiveness on factor costs, such as labor, capital, R&D and pollution abatement costs. Goal of the regression analysis is to estimate the scarcity and comparative advantage effect of each production factor, especially environmental resource. Regression results show that those industries which employ more environmental resource have higher comparative advantage in both years, which implies that Korean firms are endowed with abundant environmental resource compared to other countries. The second method is to compute the relative scarcity indices(HOVL indices) of production factors, proposed by Leamer based on Vanek's generalized Hecksher-Ohlin Theorem. This method estimates the relative scarcity of production factors by computing factor costs embodied in import and export of commodities. This method shows similar results as the regression method; i.e., trade pattern of production factors implies that the manufacturing sector in Korea is endowed with abundant environmental resource compared to other countries. Considering population density, water resource endowment, intensity of economic activity per unit area and current air and water pollution levels, it is evident that Korea is never endowed with abundant environmental resource compared to other countries. Then the abundance of environmental resource revealed by the trade patterns of commodities and production factors implies that Korea's environmental regulation level is excessively generous compared to environmental capacity, and that this increased the environmental resource endowment supplied to firms and thus distorted the inter-industry comparative advantages. Both regression and HOVL methods, on the other hand, show that overall environmental regulation level faced by the firms has been strengthened during 1993~1998.

What is the national competitive power\ulcorner What are the determinants of national competitive advantage\ulcorner In order to find these problems, this study was initiated theoretically through the international trade theory and international managerial strategic theory. The flow of studies, in connection with these competitive advantage, come into industries competitive advantage from national competitive advantage. It is understood that the flow of studies is based on the change of paradigm about the international industry environment. Today, the international industry environment has been changed into vigorous situation with the new trade system such as globalization, UR negotiation, WTO system instead of GATT. Among these environments, all enterprises in any industries should try to enhance their benefit, income profits and develop their management strategy, because it is essential for them to keep and make a profit in order to be competitive against all other rivaling enterprises. According to researchers and the ages of history, the concept and determinants of competitive advantage have been dissimiliar as followings. 1) Theory of absolute advantage : Absolute Product Cost. 2) Theory of comparative advantage : Comparative Product Cost. 3) Theory of reciprocal demand : the Reciprocal Demand Structure. 4) Theory of Hechsher-Ohlin : Factor Endowment. 5) Paradox of Leontief : the Quality of Factor Endowment. 6) Theory of technological gap : R & D. 7) Technological gap model : The Technological Gap. 8) Theory of the product life cycle : Product Life Cycle. 9) Christensen's study : Firm's character & manager's character. 10) Monopolistic Advantage Theories : Monopolistic Advantage 11) Electic theory : Ownership, location and internalization specific advantages. 12) Theory of value chain : Cost advantage, Differentiation, Focus. However all these theories have the limit of illustration regarding today's competitive situation, the Porter's theory shows well the determinants of competitive advantage with competitive strategy. Therefore, the analysis of the competitive advantage for maritime industry should be studied by the determinants of competitive advantage of nations

본 연구에서는 소유효과(endowment effect)와 손실회피(loss aversion)성향에 기인한 판매자의 판매용의가격(willing-to-sell price: WTS)과 구매자의 지불용의가격(willing-to-pay price: WTP) 간의 차이에 관한 기존 연구를 최근 점점 더 소비자들이 경험하고 있는 새로운 유통경로인 온라인 경매라는 거래상황에서 재검증하였으며, 동시에 이러한 판매자와 구매자의 용의가격의 차이에 조절적 영향을 주는 요인으로, 이득(gain)과 손실(loss)에 대한 소비자들의 휴리스틱적인 성향과 관련된 기존 연구결과들을 바탕으로 하여, 제품 유형(product type)과 소비자가 가지고 있는 목적 지향성(goal orientation)이라는 추가적인 조절변수들의 효과를 살펴보았다. 실험결과, 기존연구와 마찬가지로 판매자들이 제시하는 용의가격(WTS)이 구매자들이 지불하고자 하는 용의가격(WTP)보다 높았으며, 이 두 가격의 차이는 거래되는 제품이 소비자의 입장에서 실용적인(utilitarian product) 가치를 갖는 제품일 때보다 쾌락적인(hedonic product) 가치를 갖는 제품일 때, 또한 거래에 참여한 소비자가 향상 목적(promotion goal)을 가지고 있을 때보다 예방 목적(prevention goal)을 가지고 있을 때 더욱 두드러지는 것으로 나타났다. 마지막으로, 본 연구결과의 이론적 및 실무적 시사점, 그리고 본 연구의 한계점 및 향후 연구방향에 대해서 논의하였다.
