The purposes of the study is to examine the relationship between developmental assets, stress and risk behaviors of university students. The subject of the study is 1023 university students. Questionnaire organized by scales of developmental assets, stress and risk behaviors was used. The major findings were as follows; First, internal assets made direct effects on stress and risk behaviors. External assets made direct effects on stress. Second, mediating effects of stress were statistically significant in relations between developmental assets and risk behaviors. External assets were complete mediating effects by making effects indirectly on risk behaviors through the stress. Internal assets showed partial mediating effects.

Objective : The purpose of the study is to propose the treatment methods for problem of handwriting, micrographia in Parkinsons disease. Methods : For this purpose, foreign literatures on the subjects with Parkinsons disease was researched. Results : The results of this review is summarized as follows. The treatment methods for micrographia were applied to external cue and feedback among motor learning strategies in order to improve motor initiation. The external cues included visual, auditory, and verbal stimulations, and feedback strategy was visual stimulation. For writing with external cue or visual feedback, result in expanding the size of the letters in addition, writing task performance is maintained for a short period without those. Conclusion : Further studies are needed to examine the strategy maintained effect for long periods.

물발자국은 개인이나 지역, 집단 등이 소비하는 재화와 서비스를 생산하는데 필요한 물의 총량을 나타낸다. 물발자국은 실제 눈에 보이지 않지만 생산품에 내포되는 수자원으로서 농 축산물의 국가간 교역시 가상수의 흐름이 내포되어 있고, 이에 따라 국가별, 품목별로 농 축산물 수출입에 따른 물발자국이 산정될 수 있다. 농 축산물의 물발자국은 농업용수와 관계가 있기 때문에 수출입 정책과 농업용수 수자원 확보를 동시에 고려하기 위하여 주요 농 축산물에 대한 국가간 가상수의 흐름을 분석하고, 이에 따른 국내의 물발자국의 영향을 살펴볼 필요가 있다. 이에 본 연구에서는 농 축산물 교역을 통하여 이동되는 가상수의 흐름과 양을 산정하고 국내의 내적, 외적 물발자국의 변화를 분석하고자 하였다. 먼저 과거 5년 이상의 국가간 농 축산물의 교역량을 조사하고, 주요 농 축산물에 대한 가상수량을 적용하여 국가별, 품목별 Green, Blue, Grey 물발자국을 각각 산정하고 비교하였다. 특히 Blue water는 인위적으로 공급되는 용수이므로 수자원 절약의 측면에서 중요한 의미를 지니고 있다. 다음으로 주요 농 축산물의 국가간 물발자국 산정결과를 통하여 우리나라의 내적, 외적 물발자국을 산정하였다. 내적 물발자국은 자국내에서 생산되는 농 축산물의 가상수를 의미하고, 외적 물발자국은 수입되는 농 축산물에 대한 가상수를 의미한다. 내적, 외적 물 발자국의 비교를 통하여 품목별로 우리나라의 수자원 의존도 등을 평가할 수 있다. 본 연구결과는 단순히 농 축산물의 교역이 물품의 흐름이 뿐만 아니라 물품에 포함되는 가상수의 흐름을 동시에 고려한 것으로서 향후 농 축산물 수출입 정책과 수자원 정책을 동시에 고려하는 농축산업 관련 정책 수립시 중요한 기초자료로서 활용될 수 있을 것으로 판단된다.

It's now time for adopting u-Health according to development of internet. It is judged that it needs to research on effect of using internet health information targeting University students who are the most sensitive of internet health information. So we analyzed effect of using internet health information according to internal and external health control materials with 300 University students. As a result, If a rate of investment to the health is high, an effect of internet health information also increases as B=.004, rate of internal health control is high, it decreases as B=-.027 and rate of external health control is high, it increases as B=.037. For a University student who has steady faith about health and can control their internal health more easily, the effect of using internet health information has decreased. And for a University student who has high inclination of external dependence about health and can control their external health more easily, the effect of using internet health information has increased. So it needs to raise credibility, accuracy and accessibility of internet health information.

This study divided video content of current representative YouTube channels on Chinese language education into internal and external elements for analysis. By examining these channels, this study found that they have various external and internal elements. In addition, YouTube classes also have certain distinct characteristics that are non-existent in traditional classroom or face-to-face classes, and show potential to serve as a new educational medium that can fill the gaps in existing classroom classes. However, a large number of these channels still have problems with their internal and external elements, which seem to require not only the effort and attention of the instructors creating the videos, but also considerable time and human and material resources.

본 (本) 연구(硏究)는 문헌적(文獻的) 고찰(考察)을 통하여 이직에 영향을 미치는 요인을 규명하고 이들 요인이 기업규모(企業規模)에 따라서 이직에 미치는 영향력(影響力)과 영향경로(影響經路)가 어떻게 다른가를 보여주고자 한다. 특히 이직(離職) 결정요인(決定要因)의 선정에 있어서는 선행연구가 주로 조직(組織) 외적요인(外的要因)을 중심으로 이루어진 결과 이직에 대한 설명력이 낮게 나타나고 있음에 비추어 조직(組織) 외적요인(外的要因)과 개인적(個人的) 요인(要因)을 추가함으로써 이직에 대한 설명력을 높이고자 하였다. 이에 따른 구체적인 연구절차는 먼저 문헌연구를 통하여 이직에 영향을 미치는 것으로 나타난 요인들을 추출하였으며, 선정된 변수들을 대상으로 Price&Mueller(1981)의 이직과정(離職過程)모델에 입각하여 기업규모별(企業規模別)로 대중회귀분석(多重回歸分析)과 경로분석(經路分析)을 실시하여 이직결정요인들이 이직에 미치는 직 간접 효과(直 間接 效果)와 경로(經路)를 살펴보았다. 경로분석(經路分析)의 결과는 조직외적요인(組織外的要因)과 개인적요인(個入的要因)인 생계책임(生計責任)과 태도(態度)가 규모에 관계없이 이직의도(離職意圖)에 미치는 효과가 상당히 큰 것으로 나타났으며, 이외에 성, 이직기회(性, 離職 機會), 공정성(公正性) 또한 규모에 관계없이 이직의도에 어느 정도의 영향을 미치는 것으로 나타났다. 다만 승진가능성(昇進可能性)의 경우는 중규모기업이 대 소규모기업에 비하여 효과가 낮은 것으로 분석되었다. 그러나 모델의 설명력은 기존의 연구에서와 같이 여전히 낮은 것으로 나타났다.

The external quality factor ($Q_e$) is controlled by coupling condition between resonator and input/output ports in design of microwave filter. In this paper, we represent extracting method of external quality factor using phase response for resonator with input/output ports according to position of feed line from microstrip line resonator. The results regarding to position, coupling gap and line width for tapped line and coupled line structure are represented, and we got the exact $Q_e$ value from the this method. This results will be applied to coupled resonator filter design.

According to the research, Personal Interaction is defined that players are solving several problem to achieve goals. And if Personal Interaction is effectively done, players can get optimal experience as fun. This study analyze what kinds of extrinsic and intrinsic reward affect player's flow experience. In the result of this study, the state of flow was felt when players were aware of opportunities for personal interaction. And the personal interaction could be motivated either to achieve the high cognitive performance or by providing the equity of distribution of the objective performance in order to examine players' cognitive performance.

This study was attained to examine the relationship between the videogame players' motivation and loyalty, and to investigate the mediator effect of flow. We conducted a survey based on former researches and verified outcomes through empirical analysis. The results proposed that intrinsic and extrinsic motivation have positive influence on game loyalty, and flow has the mediating effect of this relationship. Additionally, extrinsic motivation has less impact on game loyalty and flow than intrinsic motivation does. The inherent value of game players from this paper will promote the development of VR(virtual reality) games or serious games.

This study utilized longitudinal data from the 2013 year (Secondary Middle School) to 2017 year (Secondary High School) of the Seoul Education Termination Study. Using the latent growth model and the piecewise growth model, we investigated the changes in mathematics academic achievement, internal factors(self-concept, self-control, self-assessment of life satisfaction), and external factors(school climate, guardians) as students' grades increased, and examined whether internal factors and external factors influence the changes in mathematics academic achievement. We examined whether internal and external factors influence the change in academic achievement. As a result of analysis, it was found that mathematics academic achievement remained unchanged from the first grade of middle school to the second grade of middle school, and steadily increased from the second grade of middle school to the first grade of high school, and then decreased slightly in the second grade of high school. The internal and external factors had little change. It has been found that self-concept, self-control as internal factors, and school climate as external factors influence changes in mathematics academic achievement.
