The recent entry into information society as well as the development and universalization of the Internet through rapid development of ICT technology produced a new educational method called PMP learning. PMP learning overcomes restrictions of previous education methods in terms of time and space and allows the learners to customize their learning environments according to their leads, providing voluntary education that centers on the learners. This study aims to verify the causal relationship in academic achievement of PMP learners through the theory of basic psychological desire, learning satisfaction, and learning metastasis. In order to accomplish this, a study model which applies perceived autonomy, perceived competence, and perceived relationship, which are major variables of the theory of basic psychological desire, was presented. For practical verification of the study model, survey analysis was conducted for students of R High School in Hamyang. Through this, the study aims to provide basic materials for improving the academic achievement of learners in PMP learning. It also plans to suggest educational effects that can be obtained by supporting intrinsic motivation of learners.

This study aims to investigate hypotheses for the effects of CEO's self-sacrificial leadership behaviors and employee's organizational committment of 50 Korea venture firms registered in Korea Venture Business Associations. To understand the importance of followers' characteristics in recent leadership studies on venture CEOs, it is proposed that self-sacrificial leadership behaviors will positively effect on organizational commitment. And it is also proposed that the follower's need for achievement(N-Arch) moderates in the relationship of self-sacrificial leadership behaviors and organizational commitment. After descriptive survey, research model setup, and field survey, this empirical study investigated the above mentioned hypotheses thru SPSS for Windows 12.0. It involved linear regression analysis to reveal the significant main effect of the self-sacrificial leadership behaviors. It also revealed moderating regression analysis to reveal the significant moderating effects of need for achievement between the independent variables(self-sacrificial leadership behaviors) and dependent variable(the organizational commitment). Results revealed that CEO's self-sacrificial leadership behaviors positively affected to its employee's organizational commitment under change-oriented and innovative new technology drive, self-developing environments of venture business in Korea. However, positive moderating effect of N-Arch was not supported between leader's self-sacrificial leadership behaviors and follower's organizational commitment in Korea venture firms.

Purpose - In the major global markets, such as US and China, consumer ethnocentrism has been strengtened and there is a growing need for related study. This research aims to investigate the effects of national pride and national attachment on consumer ethnocentrism, using a nationally representative dataset from 2013 Korean General Social Survey. Based on the reviews of literature in social and political sciences, two dimensions of national pride were considered: national society pride which is based on positive evaluations on the nation's democracy condition or social security system, and national achievement pride which is based on positive evaluations regarding the country's achievements in the areas of technology, art, sports, and so on. Research design, data, and methodology - The authors developed a structural model in which two types of national pride, national society and achievement pride, are proposed to affect national attachment, thus influencing consumer ethnocentrism. 1,294 surveys were used for empirical analysis. The hypotheses were tested by utilizing SPSS 22.0 and AMOS 21.0. The unidimensionality of each construct and the nomological validity were supported from the results of factor analyses and correlation analysis. Results - It was found that both national society pride and national achievement pride have significant and positive effects on national attachment. Consumers who show stronger pride on the social systems or the global achievements of Korea are more likely to remain being a citizen of the country and support the country even in wrong. Also, there was a significant and positive relationship between national attachment and consumer ethnocentrism. Korean consumers who have stronger attachment to Korea tend to express higher ethnocentrism to protect Korean labor market and to promote economic development of the country. Conclusions - The findings of this study showed that companies and government need to emphasize the country's advanced social environments or global competitiveness in technology, sports, art, and so on, to boost national attachment. With a deeper understanding on the relationships among national pride, national attachment, and consumer ethnocentrism, the authors expect that both local and foreign companies in Korea will be able to develop more effective marketing strategies and to achieve sustainable competitive advantage.

The purpose of this study was to find effects of hypertext structure and self-direction on learning performance. To reach the goal, we got 69 H highschool students and tested self-direction we treat hypertext program to them. The results found were that hypertext style(non-structure, structure) didn't effect on academic achievement but did effect 1earner's self direction. Also, we found interactive effect of hypertext structure and self-direction on academic achievement. Following studies have limits verified learning effect, because this studies are carried out in short-term research. Further studies need the study of effect of hypertext structure and self-direction on academic achievement for a long-term research. Also, further studies should accomplish the study considering learner characteristics besides self-direction and will need succeeding studies including various learning contents besides computer general curriculum.

For the sustainable management of marine ecosystem in Masan Bay, we have to assess the carrying capacity and standard of target water quality. In this research, we assume that all pollutants loads are treated in Dukdong sewage treatment plant, then we simulate the physical-biological model for prediction water quality for the achievement of standard water quality. In 2001 year, for the achievement of COD 2.5 mg/L, we need to reduce COD $90\%$, nitrogen $30\%$, phosphate $90\%$ than that of the present value, According to these results, the water quality of sewage treatment plant is required to treat COD 13.5 mg/L, nitrogen 33.3 mg/L, phosphate 6,0 mg/L. If the sewage treatment plant will be expanded much larger in 2011, it will need to be treated in COD 6.6 mg/L, nitrogen 2.5 mg/L, phosphate 5 mg/L for the achievement of water quality standard in COD 2.5 mg/L.

The purpose of the study was to explore the effect of using discussions and debates in science laboratory classes on science learning motivation, science process skills, and science academic achievement. Participants in this study were 6th grade students at an elementary school. Students in the experimental group participated in science laboratory classes using discussions and debates while students in the comparative group participated in common laboratory classes with a teacher-directed approach. The results of this study are as follows: by using discussions and debates in science laboratory classes, there were statistically positive effects on the students' science learning motivation and science process skills. However, there was no statistically significant difference in science academic achievement by using discussions and debates. Even so, in the narrative survey of the students'reactions after the class, students in the experimental group responded that it was much easier to understand the meaning of the scientific concepts when they used discussions and debates. Therefore, there is a need to investigate how to use discussions and debates effectively by introducing them at different time or in different ways, rather than considering that discussions and debates have no effect on science achievement. These findings provide science teachers and researchers pedagogical implications about utilizing discussions and debates in science classes.
