한국의 2015 개정 교육과정을 비롯, SW교육이 국제적으로 내용 및 접근성 측면에서 강화되고 있다. SW교육이 보편성에 초점을 맞춤에 따라, 교육에 대한 단기적 영향 및 효과 뿐 아니라 10-20년 후 학생들에게 미칠 장기적 성과 또한 관심을 가져야 한다. 본 연구는 강화된 SW교육이 장기적으로 학생들에게 어떤 영향을 미칠 것인지 예측하기 위해, 현 대학생들을 대상으로 중등교육에서 정보교과 경험의 차이와 대학에서의 전공선택 및 SW관련 교양 과목의 학업성취도의 차이가 관계있는지 알아보았다. 그 결과, 단순한 교과 이수 여부는 전공선택 및 학업성취도와 유의미한 관계가 없었지만, 교과 교육 내용에 따라 유의미한 차이를 보였다. 장기적 영향을 파악하기 위한 종단 연구 데이터가 없는 상태에서 본 연구의 설계 및 결과는 제한점이 있지만, SW교육의 장기적 영향의 필요성을 강조하고, 어떤 영향을 받는지에 대한 실마리를 제공했다는 점에서 의의가 있다.

The goal of this study is to investigate the consumers'shopping orientation among those who have experience in buying imported clothing and those who have no experience in buying imported foreign clothes, types of clothing they buy (planned purchase, non-planned purchase, impulsive purchasing), purchase behavior, and demographic characteristics. The data were obtained from questionnaires completed by 400 women in the Daegu area whose age was 20 years and older. The SPSS package was used for data analysis which includes a test of reliability, frequency, percentage, factor analysis, t-test, and $\chi$$^2$ test. There were significant differences in clothing shopping orientation, impulsive purchasing, use of information sources, store selection standards between groups who had experience of buying imported clothing and had no experience of it. Also, there were significant differences in education levels, income Levels, marital status between two groups.

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.
