The purpose of this study was to investigate the goal and strategy differences in the Social Problem Solving (SPS) according to ages and interaction targets of children. The subjects were 48 children between the ages of 3, 4 and 5 years. Their SPS behavior was observed as it occurred naturally in free play interactions. The data were analysed by one-way ANOVA, Duncan's multiple range, repeated measures, and t-test. The results showed that there were significant goal and strategy differences in SPS behavior according to age and interaction targets of children.

국제적으로 기업활동의 수직적 분화와 현지경영이 가속화 됨에 따라 국제특송시장규모가 확대되고 있다. 글로벌 특송기업들은 확대되고 있는 국제물류시장에서 점유율을 증대시키고자 M&A를 통해 대형화하고 글로벌화하고 있는 데 반하여 우리나라 특송업체들은 규모의 영세성으로 국제물류시장에서 경쟁에 밀리고 있다. 본 연구에서는 우리나라 국제특송업체의 현황을 진단하고 경쟁력을 제고할 수 있는 방안을 탐색하고자 하였다. 연구결과에 의하면 국제특송산업의 특성요인과 이러한 시장에서의 경쟁적 특성요인이 특송업체의 두 유형의 글로벌 전략에 중요한 영향을 미치고 있는 것으로 나타나고 있다. 첫 번째 유형의 전략은 특성화전략(SCM전략, 3자물류전략, 토탈물류전략 및 차별화전략)이며 두 번째 유형의 전략은 M&A와 종하물류기업화에 의한 규모확대와 단계별 시장진출전략이다. 이러한 두 유형의 전략이 제대로 실행되어야만 국제특송업체의 경쟁력을 증대시킬 수가 있으며 이를 위한 정부의 체계적인 지원이 필요한 것으로 나타나고 있다.

디지털 융합을 위한 교육은 다양한 학문과 기술들이 컴퓨터를 중심으로 융합하는 것이므로 교육 범위와 방법이 매우 상이하다. 따라서 교육 계획과 강의전략을 정형화하기 어렵기 때문에 개념적인 정보를 제한적으로 추천하는 문제점이 있다. 본 논문에서는 스피어만 상관 계수를 이용하여 교육 계획과 강의 전략을 제시하기 위한 시스템을 제안한다. 이 시스템은 학계와 산업계의 요구를 기반으로 한 정보로부터 강의 전략 연관성을 찾아 서열화하고, 사용자의 상황과 특성에 적합한 강의 전략 정보를 목록으로 제공하여, 제한적인 개념적 정보 추천의 단점을 해결한다. 성능 실험은 기존의 서비스 시스템들과 비교하여 효과성을 측정하여 정확도와 재현율로 표현하였으며, 성능 실험 결과 정확도는 90.4%, 재현율은 77.6%로 나타났다.

This study examines how teaching metacognitive strategies to students in a sixth-grade mathematics class affects their metacognitive awareness. Participants were 36 sixth-grade students in a middle school affiliated with the Ministry of National Education of Turkey in the 2020-2021 academic year. The students in the experimental group (n = 18) were taught a total of 40 mathematics lessons for eight weeks to improve their metacognitive awareness. The students in the control group (n=18) were taught mathematics in line with the regular mathematics curriculum. Using the Jr. Metacognitive Awareness Inventory, participants in both groups took a pre-test at the beginning and a post-test at the end of the study. To better interpret the data obtained, various statistical tests were performed. The pre-test and post-test averages of the groups were compared using the t-test for the normally distributed data for dependent and independent groups. The pre-test results showed no significant difference between the metacognitive awareness scores of the experimental and control groups (p>0.05). The comparison of post-test averages showed that students' metacognitive awareness differed significantly in favor of the experimental group (p<0.05). According to this, it was concluded that metacognitive strategy teaching in mathematics courses positively affected students' metacognitive awareness levels.

This paper presents simulated and experimental test results of optimal control algorithm for an encapsulated ice thermal storage system with full capacity chiller operation. The algorithm finds an optimal combination of a chiller and/or a storage tank operation for the minimum total operation cost through a cycle of charging and discharging. Dynamic programming is used to find the optimal control schedule. The conventional control strategy of chiller-priority is the baseline case for comparing with the optimal control strategy through simulation and experimental test. Simulation shows that operating cost for the optimal control with chiller on-off operation is not so different from that with chiller part load capacity control. As a result from the experimental test, the optimal control operation according to the simulated operation schedule showed about 14 % of cost saving compared with the chiller-priority control.

The purpose of this study is to investigate the effects of the job stresses perceived by R.O.K. naval crews on turnover intentions and job satisfactions. Especially, this study aims to derive the policy implication for the trait characteristics by comparing the job attitude between the surface naval ship and submarine crew. For this purpose, we surveyed 1,000 naval crews. Then, multiple regression analysis was performed. Next, a T-test was conducted to test statistical significance of group differences. First, the job stresses perceived by naval crews were higher in the order of physical environments, overworks, compensation incompetence, lacks of autonomy, and conflicts with people. Second, the job stresses perceived by submarine crews were higher than that of surface naval ship crews. It was also proved statistically significant by the T-test. Third, the physical environments, lacks of autonomy, conflicts of relativity, and inadequate compensation stress have a positive statistically significant effect on turnover intentions of naval crews. Fourth, lacks of autonomy, conflicts of relativity, and inadequate compensation factors have a statistically significant negative effect on the job satisfactions of naval crews. Finally, multiple regression analysis was performed between the independent and dependent variables of the naval crews, and the policy implications were derived.

Purpose: The purpose of this study is to examine effects of a multifactorial program for preventing the frailty of older adults and effects of a follow-up program applying a capacity building strategy. Methods: A quasi-experimental pretest-posttest design was used for the nonequivalent control group. The follow-up group (n=75) and non-follow-up group (n=68) received the same multifactorial program comprising muscle strength exercise, cognitive training, and psychosocial programs for 12 weeks. After completion of multifactorial program, the follow-up group took follow-up programs applying the capacity building strategy for following 12 weeks. The data of physical function, cognitive function, and psychological function, and self-rated health were collected from both groups three times: before intervention, after intervention, and 12 weeks after intervention. The data were analyzed using $x^2$ test and t-test. Results: In comparison with the non-follow-up group, the scores of Timed Up & Go Test, and physical activities energy expenditure were significantly improved in the follow-up group. Conclusion: These results indicate that a multifactorial program with follow-up adapting the strategies of capacity building for the older adults group is feasible to prevent the physical frailty in community.

This study examines the effects of two motivational orientations on the use of language learning strategies at overall, category, and specific-item levels. 184 students (males and females) from a Korean university responded to the following two questionnaires: the Motivational Orientation Questionnaire (MOQ) developed by the author and Oxford's Strategy Inventory for Language Learning (SILL). The results showed that both integratively- and instrumentally-oriented students were moderate strategy users overall. Integratively-oriented learners were found to use learning strategies more often and a broader spectrum of strategies than instrumentally-oriented learners. A noteworthy finding, however, is that strategy use was not motivation orientation-specific. In other words, the two motivational groups were found to share the similar patterns of strategy use. Independent samples t test results revealed that integratively-oriented students exhibited significantly greater use of overall strategy than instrumentally-oriented students. This phenomenon held true for the use of cognitive, metacognitive, and social categories. At the specific item levels, 13 of the total 50 individual strategies were shown to be employed significantly more often by integratively motivated learners than by their instrumentally motivated peers.
