Enhancement of computing education became an international phenominon including South Korea's revised national curriculum 2015. As the enhancement begins to focus on universal computing education, researches to investigate long-term effect of the enhancement is needed. To explore whether the reinforced computing education will bring which long-term impacts, this study investigated university students' experience on computer subject in their secondary schools, and major selection and achievement in a college computing course. As results, there was no statistically significant relation of taking the computer subject per se and major selection and achievement, but significant relation between contents of the subject, and major selection and achievement. This study has limitation on design and results lacking longitudinal data but contributes emphasizing need of longitudinal study to measure long-term effect of enhancement of computing education and providing clues of what impact it would bring.

In future, since the user experience plays a more and more important role in the development of today's communication systems, quality of experience (QoE) becomes a widely used metric, which reflects the subjective experience of end users for wireless service. In addition, the energy efficiency is an increasingly important problem with the explosive growth in the amount of wireless terminals and nodes. Hence, a QoE-aware energy efficiency maximization based joint user access selection and power allocation approach is proposed to solve the problem. We transform the joint allocation process to an optimization of energy efficiency by establishing an energy efficiency model, and then the optimization problem is solved by chaotic clone immune algorithm (CCIA). Numerical simulation results indicate that the proposed algorithm can efficiently and reliably improve the QoE and ensure high energy efficiency of networks.

Purpose: This study attempts to investigate causal and intervening conditions for sport participation of Korean immigrants in the United States. Research design, data, and methodology: Grounded theory approach was used to develop a conceptual framework that presents the psychosocial processes that occur in immigrants' experience of sport participation. Participants were selected purposefully for information-rich cases. Korean immigrants with current experience of having periodically participated in sports were the criterion for sample selection. Based on selection criteria, 9 Korean immigrants took part in interview. The interview discussions were taped and transcribed verbatim into a Word file. The process for data analysis included four grounded theory approaches of purposive and theoretical sampling, an open and axial coding, memo writing, and finally the development of the conceptual framework. Results: Six concepts were revealed in the causal conditions that facilitate the process of immigrants' sport participation in the states: Personal experience, significant others, personality, physical environment, psychological well-being, and social connection. Three concepts were revealed as the intervening conditions that block the process of immigrants' sport participation in the states: Conflict with cultural change of organization, Pressure at workplace, and Economic constraints. Conclusions: Conceptual model presents causal and intervening factors. Further implications were discussed.

Corporations are pursuing maximum returns from their R&D investment. They are also interested in sound measures to quantify returns. In fact, they use various measures and criteria for measuring returns from the R&D investment. But the fundamental problem is that there is no generic and widely acceptable measures and criteria. To make things more complicated, measures are very powerful and influential to the people in the corporations. Herbert Simon already indicated that people do many things but people usually do their best for the only tasks which are measured. Many researchers, like Chester(1995), are interested in R&D productivity measures and risks because what the company measures really influence R&D people and output. This article present design concepts of the R&D project selection and evaluation system in POSCO(Pohang Iron & Steel Company). This is an output extract from the 6-month joint activities with POSRI(POSCO Research Institute) researchers and POSCO R&D personnel. Process changes, new organizations and new selection and evaluation criteria are developed to improve R&D performance and to enhance technology management of the POSCO. This article covers new selection and evaluation criteria only. We would like to share our experience about how we redesign the selection and evaluation of R&D projects. We also bring insights how we seamlessly integrate 4 different project selection and evaluation steps as a whole. We hope that this case will give you a clue to improve your R&D management.

Objectives: The purpose of the study is to find out the effect of part-time employment experience on adaptation to university life in dental hygiene students. Methods: A self-reported questionnaire was completed by 288 dental hygiene students in Seoul and Gyeonggido from September to October, 2014. The questionnaire consisted of general characteristics of the subjects(5 items), part-time employment experience(6 items), and adaptation to university life(53 items). The instrument for adaptation to university life was adapted from Baker and Sirky and modified by Kwon. Likert 5 point scale adaptation included personal emotion adaptation, academic adaptation, social adaptation, and university environment adaptation. Cronbach's ${\alpha}$ was 0.80 in the study. Results: The adaptation to university life was 3.0 points. The higher the economic level was, the higher the personal emotional adaptation(p<0.001) and academic adaptation were(p<0.05). The adaptation to university life was positively influenced by tuition support by parents and part-time employment(p<0.05). The part-time employment was significantly helpful to future job selection, social adaptation, and university environment adaptation(p<0.001). Economic stability and advantage of future job selection had a positive influence on the adaptation to university life. So the adaptation to university life was proportional to younger age, economic stability, and advantage to future job selection. Conclusions: It is very important to give a positive motivation and stimulation, and a careful counseling to the students in part-time employment. In order to encourage the part-time employed students, major-related part-time job opening must be given.
