  • This study examined an effect of mother's smart device overdependence and short-term longitudinal mediation effect of mother's responsiveness on children's overindulgence tendency in smart devices. A total 144 children-mother dyads(male 73, female 71) participated in the study. The results of path analysis were as follows. The mother's smart phone overdependence and children's overindulgence tendency in smart devices were measured at time 1 and mother's responsiveness and children's overindulgence tendency were measured at time 2, six months later. When Time 1 children's overindulgence tendency in smart devices was controlled, Time 1 mother's smart phone overdependence significantly predicted time 2 children's overindulgence tendency. This study suggested empirical findings that caregiver's smart device were related with children's overindulgence tendency.

  • 전면안전조치 협정국인 이라크의 비밀 핵무기 계발과 핵 개발 의혹국인 북한의 특별사찰 거부로 야기된 IAEA의 안전조치강화방안(Strengthened Safeguards System, SSS)은 기존의 IAEA 안전조치에 대한 효과성과 효율성을 제고하기 위하여 마련된 방안이다. 이 중 안전조치의 효과성은 핵물질의 전용 방지를 정확하고 빠르게 탐지하는데 있으며 이러한 안전조치의 효과성은 기술적인 방법과 정치적인 방법이 조화를 이루면서 획득될 수 있다. 기술적인 면에서는 정보제공과 접근확대에 대한 IAEA의 하부구조 개발이 순조롭게 진행됨으로써 효과성을 기대할 수 있다. 반면 정치적인 면에서의 효과성은 전면안전조치 협정국으로서 원자력에 대한 기술력을 확보한 국가의 조기참여예상으로 긍정적인 면이 있으나 이라크 및 북한, 그리고 부분 안전조치협정국의 참여 불투명은 SSS의 효과성을 단기적으로 떨어뜨리는 요인으로 작용할 것으로 딘인다. 따라서 IAEA는 상기불투명국의 SSS에의 참여를 유도하는 것이 안전조치의 효과성을 확보하기 위한 남은 과제라 할 수 있다.

  • This study attempt to use secondary data from KIS-Value to understand how rapid globalization strategy affects BGF's performance defined five categories such as sales volume, return on investment, net profit per employee, increase in sales, and increase in net profit per employee. In particular, this research defines the BGF based on the export ratio within five years after the establishment and classifies BGF into three levels according to 25%, 50%, and 75% concentration of exports. The main results of this study were first, the rapid internationalization strategy was proven to have a sales effect in the short and long term, and in particular, the short term effect was more significantly compared to the long term effect. However, the impact on the return on investment(ROI) of BGF was found that the more stringent the BGF level, the more short-term effect on ROI, but the longer-term effect was diluted according to time. Third, the sales growth rate is significant in the short-term depending on the BGF level, but do not have long-term effects same as ROI. On the other hand, the growth rate of net profit has shown that the BGF strategy has a negative (-) effect over the long term. In particular, the higher the BGF level, the greater the negative impact on the increase in net profit.

  • The purpose of this study was to investigate the effects of short-term Maum Meditation and to compare effects according to the length of the training period on mental health of teachers. In this research, 2 types of design were used which were one-group pre-posttest design and descriptive study. In short-term Maum Meditation group, 2 times of surveys were carried out, 75 teachers in the faculty training filled out the structured questionnaire. In Long-term Maum Meditation group, 101 teachers who were attending Maum Meditation above one-year filled out the structured questionnaire. The data were analyzed by SPSS WIN 14.0 program. The results showed that there was a significant difference in mental health including 9 subscales for short-term Maum Meditation group. Also, in long-term Maum Meditation group, there were significant differences in mental health excepting paranoid ideation. It was founded that Maum Meditation is the way for the mental health promotion in short-term and long-term period. So it is necessary to develop program according to training period for not only clinical application but also to strengthen coping ability for stress.

  • The purpose of this study was to investigate the change of physical fitness, MDA, SOD after short-term weight reduction through exercise, food restriction and exhalation of sweat among Taekwondo players. The subjects ten male collage Taekwondo players with excellent practical skills, and more than seven years of experiences. They were asked to reduce about 5% of their body weight in seven days. Physical fitness levels were analyzed through grip strength, muscle endurance, flexibility, power, agility, balance, reaction time and MDA and SOD through blood test. The results of this study were as follows; First, there was no significant change in physical fitness due to short-term weight reduction in muscle strength, muscle endurance, flexibility, power, agility, balance and reaction time. Second, The change of MDA and SOD, resulting from short-term weight reduction did not show significant difference statistically. Therefore, the results of this study indicate that the Taekwondo players' short-term weight reduction of 5% of their body weight did not influence on their athletic performance and physiological capacity. Therefore athletes and coaches should endeavor to take exercise, dietary, and dehydration into consideration when conducting 5% of their body weight reduction in a week.

  • This study attempted to: (1) operate a Strengths-based case management program; (2) determine the effectiveness of strengths-based case management for the elderly; (3) evaluate the effect of the coordinating program on the capabilities of ADL, IADL, and life-satisfaction of the elderly. The subject of this study was 8 home-bound elderly in lowest income class in Gwang-ju City. The program was practiced from November 2008 to April 2009 for 6 months period. The outcome of study has shown that strengths-based case management has determined a fair of amount of effectiveness in carrying out their short-term tasks. The program tried to assess the strengths of the elderly, and evaluate the outcomes of the program using ADL, IADl items and life-satisfaction developed for the study. The data collected by pre-test and post-test of the program showed that the scores of life-satisfaction were improved statistically significantly. But capabilities of ADL, IADL items were slightly improved, but not statistically significant. Successive effort to operate strengths-based case management must be required for the improvement of capabilities of ADL, IADL, and quality of life of the elderly.

  • 환율의 과도한 변동이 무역량을 위축시키는지에 대하여 선진국을 대상으로 그 동안 많은 연구가 있어 왔다. 최근 한국은 1990년 이후 제한하여 오던 환율의 변동허용폭을 폐지함에 따라 환율의 과도한 변동을 경험하고 있다. 본 연구는 한국의 경우 환율의 변동성이 원유수입(原油輸入)에 미치는 효과를 장단기(長短期)로 구분하여 Johansen에 의하여 개발된 공적분기법으로 분석하였다. 분석결과에 의하면 단기에 있어서 환율의 변동성은 원유수입을 감소시키나 장기에는 원유수입에 큰 영향을 주지 않는 것으로 나타났다. 이는 단기에는 원유(原油)의 비축물량이 존재하여 가격의 불확실성이 원유수입을 감소시키나, 장기적으로는 원유수입이 비경쟁적 수입이고 수입기업이 환위험을 감소시키는 기법등을 사용한 결과로 환율의 변동성이 원유수입에 큰 영향을 주지 않았다고 할 수 있다.

  • The purpose of this study is to develope a forecasting model to implement short-term Congestion Management Program (CMP) based on TDM strategies in Seoul. The CMP is composed of three elements: 1) setting a goal of short-term traffic management. 2) developing a model to forecast the impacts of TDM alternatives, and 3) finding TDM measures to achieve the goal To Predict the impacts of TDM alternatives, a model called SECOMM (SEoul COngestion Management Model) is developed. The model assumes that trip generation and distribution are not changing in a short term, and that only mode split and traffic assignment are affected by TDM. The model includes the parameter values calibrated by a discrete mode choice model, and roadway and transit networks with 1,020 zones. As a TDM measure implement, it affects mode choice behavior first and then the speeds of roadway network. The chanced speed again affects the mode choice behavior and the roadway speeds. These steps continue until the network is equilibrated. The study recommends that CMP be introduced in Seoul, and that road way conditions be monitored regularly to secure the prediction accuracy of SECOMM. Also, TDM should be the major Policy tools in removing short-term congestion problems in a big city.
