With the rise of China, the power and hegemony is moving to China in East Asia. The foreign policy of the China government is directly or indirectly affecting Korea, neighboring countries and the world. China is advocating a new international policy, a new security system, silk road policy and a new paradigm. China is a newly emerging powerful nation in Asia, and it is clear that China has the economic power to reestablish the Asian order and take over the hegemony. In addition, we want to run the world supremacy with the United States in political, economic, military and diplomatic sectors. In order to overcome the crisis of the Korean peninsula, which is being triggered by North Korea's nuclear and missile development, we are in the position to do our best to cooperate with Korea, the United States and Japan and further improve relations with China. In this study, I analyzed the policy of Southeast Asia and China macroscopically.

This study is concerned with the estimation of daily instantaneous maximum wind velocity in the meteorological major cities (selected each 17 points) during the yearly 1973-2016. The purpose of this paper is to present the turbulence statistic characteristics (probability distribution, correlation coefficient, turbulency intensity, shear velocity, roughness length, turbulence integral length, skewness, and kurtosis) of the daily instantaneous maximum wind velocity. In the processes of analysis, used observations data obtained at Korea Meteorological Adminstration (KMA). The estimation of non-Gaussian load effects for design applications has often been treated tacitly by invoking a conventional wind design load on the basis of Gaussian processes. This assumption breaks down when the instantaneous wind velocity processes exhibits non-Gaussianity. From the analysis results, the probability distribution of the daily instantaneous maximum wind velocity shows a very closed with non-Gaussian in the ensemble population 748, the correlation coefficient shows larger at inland area more than coastal area.

Recently, safety issues in companies and public institutions are no longer a task that can be postponed, and when a major safety accident occurs, not only direct financial loss, but also indirect loss of social trust in the company and public institution is greatly increased. In particular, in the case of a fatal accident, the damage is even more serious. Accordingly, as companies and public institutions expand their investments in industrial safety education and prevention, open AI learning model creation technology that enables safety management services without being affected by user behavior in industrial sites where high-risk situations exist, edge terminals System development using inter-AI collaboration technology, cloud-edge terminal linkage technology, multi-modal risk situation determination technology, and AI model learning support technology is underway. In particular, with the development and spread of artificial intelligence technology, research to apply the technology to safety issues is becoming active. Therefore, in this paper, an open cloud platform design method that can support AI model learning for high-risk site safety management is presented.

The purpose of this study was to investigate whether Korean children's being addiction to computer game had an effect on physical health(headache, insomnia, indigestion, cardivascular). We considered both direct effects of that addiction and indirect effects which caused an negative emotion(anxiety). For this study, we collected data from 800 students of grades and 6 in Daejeon, Korea. Among them, we analyzed the data of 572 students[408 boys(71.3%) and 164 girls(28.7%) respectively] who had played computer games for a long period of time(two years or more). Reliability of the scale used on this study was a proper level by $.64{\sim}.91$ and we operated an analysis of structural equation pattern to make relationships of variable causes clear. As a result of examining an index of fitness of each model, it was proved for the fitness of every model(all GFI >.931, all CFI >.939, all NNFI >.929, all RMSEA <.046) to be acceptable. Not only the computer game addiction affected(all ps<.001) directly on physical symptoms(headache ${\beta}$=.211, insomnia ${\beta}$=.289, indigestion ${\beta}$ =.214, cardivascular ${\beta}$=.349), but also it affected(${\beta}$=.458, p<.001) on anxiety. In addition, the effect of anxiety on physical symptoms(headache ${\beta}$=.419, insomnia ${\beta}$=.375, indigestion ${\beta}$=.498, cardivascular ${\beta}$=.328) was significant. As a result of yielding the indirect effects of computer game abuse mediated by anxiety, headache was measured up ${\beta}$=.192, insomnia ${\beta}$=.172, indigestion ${\beta}$ =.228 and cardivascular ${\beta}$=.151. The computer game addiction caused 21% of anxiety and this mediate model proved that the computer game addiction caused 30% of headache, 32% of insomnia, 39% of indigestion, and 34% of cardivascular symptom. As a result of this study, the computer game addiction has a negative effect on physical health both directly and indirectly. Especially, cardivascular was influenced most extremely, then insomnia, indigestion, and headache in order. The implications gleaned from this study were discussed with considerations for future study and practical aspect.

The present study purposed to survey dental hygiene students who will play important roles in guidance and to utilize the data as basic information for setting the direction of dental hygienists' efficient guidance for antismoking and developing antismoking education programs. For this purpose, a survey was conducted with 400 students at the Department of Dental Hygiene in Daejeon, Jollabuk-do and Jollanam-do during the period from May 19 to June 14 in 2008, and drew conclusions as follows: As to correlations among self-efficacy, smoking knowledge, and perception on guidance for antismoking, positive correlation was observed between self-efficacy and smoking knowledge (r=0.102), between self-efficacy and perception on guidance for antismoking (r=0.272), and between smoking knowledge and perception on guidance for antismoking (r=0.352). As to factors affecting perception on guidance for antismoking, the effect was high in order of perception on smoking, smoking knowledge, and self-efficacy. That is, perception on guidance for antismoking was more positive in those who thought that smoking must not be allowed, those with high smoking knowledge, and those with high self-efficacy. For dental hygienists' clinical activities for efficient prevention of smoking and guidance for antismoking, it is necessary to develop curriculums containing various practical contents.

During the 2nd World War, several Coal-to-Liquid (CTL) plants were operated in Germany and England to convert coal to large volumes of liquid fuel. Big oil fields discovered in the Middle East after the war supplied crude oil at the low price and all CTL plants were forced to shut down. However, South Africa (Sasol) built a CTL plant in 1955 and 2 more plants afterward and the current production of coal-derived synfuel reached 150,000 bbl/day. Recently, the sustained high crude oil price and the fear of the "peak oil" rejuvenated the interest of CTL and several CTL projects are in progress. China established a plan to build CTL plants with the total capacity of 30 million tons of synfuel per year by 2030. China is building a direct coal liquefaction plant which is scheduled to produce 20,000bbl/day of synfuel in 2008. There are 8 CTL projects in USA either in the planning stage or in the ground-breaking stage. CTL projects are also carried out in Australia, Philippines, New Zealand, Indonesia and India. Korea needs to approach the CTL project in the perspective of the national energy security. In this paper, the history, the status, current activities and the prospect of CTL are described.

This study was intended to investigate the effect of life stress of university students on the suicidal ideation and to verify the mediating effect of personal mental health on a relationship between life stress and suicidal ideation. Therefore, this study collected data from 491 university students who are enrolled in 4 universities located in Daejeon Metropolitan City, Chungnam, and Chungbuk. According to the main findings of this research, life stress, suicidal ideation, and mental health had statistically significant correlation. Secondly, life stress not only makes direct effect on the suicidal ideation, but makes indirect effect through a mediating variable, the mental health, as well that mental health is verified to mediate a relationship between life stress and suicidal ideation. The research results suggest that mental health of university students is impoverished when life stress is higher, and can make effect on the suicidal ideation due to continual phenomenon of losing general function of life. This study investigated how counselors can intervene convergence policy approach with mental health of clients that affects the relationship between life stress and suicidal ideation of university students, and suggested implication and limitation of this study and suggestions for a follow-up study.

본 연구는 1990년대 밀리터리 패션에서 성적 이미 지의 표현양상을 살펴보고 각각의 미적 특성과 형성 요인을 분석하여 현대 여성의 다양한 미적 가치와 미의식을 이해하고자 한다. 1, 2차 세계대전을 계기로 자연스럽게 등장한 밀 리터리 패션은 20세기 초반에 여성의 사회참여와 지 위 향상으로 인해 실용성과 기능성을 추구하였고 중 반에 들어서면서 히피와 젊은 세대들에 의해 반전운 동의 일환으로 입혀져 안티패션의 의미를 내포하게 되었으며 후반에는 포스트모더 니즘으로 인해 다양성 을 추구하는 복고풍의 패션 트랜드로서 각종 컬혜션 에서 부각되었다. 그 결과 밀리터리 패션은 기존의 남성적 이미지뿐만 아니라 여성적 이미지도 표현하 게 되었다. 이러한 밀리터리 패션에 나타난 성적 이 미지는 권위적 이미지와 공격적 이미지의 남성적 이 미지와 보수적 이미지와 과시적 이미지, 관능적 이미 지의 여성적 이미지로 표현되어 나타났다. 남성적 이미지는 자유주의 페미니즘과 관련하여 남성 중심적 사고 방식에 도전하고자 하는 여성들의 자아의식이 한층 강하게 작용한 일종의 반 패션 현 상으로 권위적 이미지와 공격적 이미지로 특정지을 수 있다. 첫째, 권위적 이미지는 주로 고전적 군복과 제복의 이미지를 차용해 군복이 가지는 권위와 위엄을 표출 하였으며 남성 우월주의에 기초한 영웅주의를 가시 적으로 표현하였다. 이는 떳떳하게 자신의 위치를 세 우고자 하는 여성들의 욕구를 대변하였으며 영웅주 의와 가부장제도가 그 형성요인으로 작용하였다. 둘째, 공격적 이미지는 권위적 이미지에 대한 저 항과 기존의 성 정체성에 대한 저항으로써 전위적인 형태와 해체적인 표현으로 본래의 위엄있는 군복의 이미지를 무너뜨려 남성다웅의 표면적인 메시지를 약화시키고자 하였으며 반체제 정신, 성 정체성에 대 한 저항, 해체주의가 그 형성요인으로 작용하였다. 여성적 이미지는 급진주의 페미니즘과 관련하여 여성 본래의 성을 부각시키고 여성이 주체가 된 여 성중심적 사고로 여성의 감성적 심리를 패션을 통해 표현하고자 하였으며 보수적 이미지, 과시적 이미지, 관능적 이미지로 특징 지을 수 있다. 첫째, 보수적 이미지는 남성적 영역이라고 믿어왔 던 군복에 여성성을 강조하여 가늘고 유연한 실루엣 과 곡선적인 라인, 색채. 심플한 디테일만으로 밀리 터리 패션을 표현하여 남성중심의 이데올로기에서 벗어나 여성도 사회의 중심이 될 수 있음을 시사하 였으며 남성 권위의 추락이 그 형성요인으로 작용하 였다. 둘째, 과시적 이미지는 전통적 군복이 과거의 상 류층 엘리트들만의 아이템이었듯이 현대의 여성들은 신분과 매력의 과시를 표현하고자 금속 단추나 벨트 등 기타장식을 부각시킨 밀리터리 패션을 착용하였 으며 엘리트층에 대한 동경이 그 형성요인으로 작용하였다. 셋째, 관능적 이미지는 신체의 간접적인 노출과 직접적인 노출을 통해 여성의 신체에 의한 에로틱한 관능미를 부여하고자 하였으며 나르시시즘과 보이고 자 하는 욕구, 성적 유희가 그 형성요인으로 작용하였다. 그러므로 밀리터리 패션에 나타난 성적 이미지에 관한 연구는 패션을 통해 자아를 표현하고 미적으로 자기완성의 방편을 삼으려고 한 현대 여성들의 가치 관과 미의식을 이해하며 이를 충족시키고자 하는 패 션 트랜드와 디자인 개발에 도움이 될 것이다.
