This paper considers the historicity and aesthetical implications of in the art world of Paul Ryan(1943-2013) who designed the aestheticization of relational circuit of society by realizing the value of social transformation being inherent in video with cultural practices and suggesting the interdisciplinary method of leaning and research in the early video art history. To do this, in Chapter II, I review the first artwork presented firstly in the art gallery exhibition "TV as a Creative Medium" in 1969, in which Ryan proposed a video medium as a communication system and experimented the concept of 'feedback' in Cybernetics. And Chapter III focuses Ryan's discursive activities contributed to magazine Radical Software and artist-collective Raindance Corporation with growing interest in communication technology. At this time, Ryan regarded video medium as the tool for cybernetic expansion. Finally Chapter IV deals with the development of ecological method based on "a shared perception of environmental realities" and verifies Ryan's vision that video medium would be most effective means of social change and communication.

The purpose of this study was to investigate the degree of mental health among nursing students in Korea and identify factors influencing the tendency to mental health. A self-report survey was conducted with South Korean nursing students who were from 19 to 23 years old. 269 nursing students were included in the study. The instruments utilized in the study were Symptom Checklist-90-Revision, Stress and multidimensional coping. Data were analyzed using descriptive statistics, Pearson correlation and Simultaneous multiple regression with SPSS WIN 20.0. The average mental health score of the participants was 0.57. Significant predictors for mental health 'College-level stress', 'Self-criticism', 'Passive withdrawal', 'Nursing satisfaction' and 'Health state'. The study findings suggest that nursing students require special concern regarding the risk of mental health. Multi and interdisciplinary mental health promotion program will enhance the mental health of nursing students.

유리 소재는 뛰어난 기계적, 화학적, 광학 특성으로 인해 다양한 영역에서 광범위하게 활용되어 왔으며, 최근에는 특정 물성이 강화된 기능성 유리 수요가 다양한 산업 영역에서 급속히 증가하고 있다. 유리 소재 분야에서의 연구 개발은 유리 특유의 비정질 구조 및 다원소 조성 특성에 의한 복합성 때문에 전통적으로 경험에 기반한 실험 기법에 의존하여 왔다. 그러나 적용 분야에 따른 맞춤형 물성 강화에 대한 필요성이 증대됨에 따라, 핵심 물성 발현 원리 등을 원자 단위에서 이해하고 이를 바탕으로 기능성 유리 소재를 설계하는 접근법이 주목받고 있다. 원자단위 시뮬레이션 및 이론 기반 모델링은 유리 소재의 다양한 물성과 조성 변화에 따른 원자 구조의 상관관계를 매우 효율적으로 분석할 수 있는 기법이다. 본 기고문 에서는 밀도범함수이론, 분자동역학 및 위상속박이론을 활용한 기능성 유리 소재 개발 및 연구 동향에 대해서 소개하고자 한다.

Because chronic pain disorder may has multiple causes or contributing factors, including physical, psychological, and socio-environmental variables, the treatment of patients with the disorder requires biopsychosocial approaches in a multidisciplinary setting. In treating chronic pain, it is important to address functioning as well as pain, and treatment should be to increase functional capacity and manage the pain as opposed to curing it. Therefore treatment goal should be adaptation to pain or minimizing pain with corresponding greater functioning. Treatment begins with the initial assessment, which includes evaluation of psychophysiologic mechanisms, operant mechanisms, and overt psychiatric comorbidity. Psychiatric treatment of the patients requires adherence to sound pharmacologic and behavioral principles. There are four categories of drugs useful to psychiatrist in the management of chronic pain patients : 1) narcotic analgesics, 2) nonsteroidal antiinflammatory drugs, 3) psychotropic medications, and 4) anticonvulsants, but antidepressants are the most valuable drugs in pharmnacotherpy for them. Psychological treatments tend to emphasize behavioral and cognitive-behavioral modalities, which are divided into self-management techniques and operant techniques. Psychodynamic and insight-oriented therapies are indicated to some patients with long-standing interpersonal dysfunction or a history of childhood abuse.

Background : The aim of this study was to confirm the risk factors for low back pain and injury to improve the prevention and treatment of lower back pain. Materials and Methods : An epidemiologic study of low back pain and injury was performed with questionnaires distributed to 471 women working at Yeungnam university hospital. The differences in low back pain and injuries among various hospital departments were analyzed by a one-way analysis of variance (ANOVA), and the relevant factors included in the questionnaire were determined by a factor analysis. Results : The frequency of low back pain in women in the department of diet and in the maintenance department was higher than among the other departments. The frequency of low back pain was mainly related to the frequency of psychosomatic symptoms. In addition, the low back pain was partially related to the frequency of psychosomatic symptoms and partially related to the frequency of pushing during the workday. The degree of disability from low back pain was increased by lifting and hard physical work and was related to the frequency of psychosomatic symptoms and the degree of work dissatisfaction. The frequency of low back injury was increased by increased standing time during work and hard physical work. The frequency of low back injury was related to advancing age and in part to psychosomatic symptoms. Conclusion : Lower back pain and its associated complications are related to psychosomatic factors and type of work. Lower back injury is related to physiological factors such as age. For the prevention and treatment of lower back pain, a multidisciplinary approach is required.

지반오염을 조사하기 위해서는 시추작업을 통하여 시료를 채취하는 방법이 일반적이지만, 실시간으로 원위치에서 다양한 오염물질들의 오염도 변화를 체계적으로 모니터링하는 것은 대단히 어렵다. 본 연구에서는 Frequency Domain Reflectometry(FDR) 장비를 고안하여 지반의 유류오염을 파악하기 위한 유전율 측정법의 실험적 접근을 시도하였다. 구체적으로 포화 및 불포화 매질에 대한 오염도의 측정 및 오염도와 체적함수비의 관계를 측정하여 유전율 반응으로부터 매질의 물성치를 파악할 수 있는 것을 확인하였다.

In recent years, the state of the water quality of Han river has been among the top public concerns. This paper measures economic value of multiple environmental impacts of improved water quality of Han river using a choice experiments approach. The choice works that take into account trade-offs between price and environmental attributes for a preferred option turned out to be within respondent' ability to reveal their preferences, and the willingness to pay estimates were statistically significant. This study allows policy-makers to provide useful quantitative information that can be referred to as a benchmark for upcoming water projects.

A probabilistic approach considering uncertainties was employed to investigate the effects on the material characteristics and strength of nuclear bio-logical shield concrete walls, when exposed to long-term radiation during the entire service life. Time-dependent compressive and tensile strengths were estimated by conducting the neutron fluence analysis. For the contaminated concrete, individual compressive and tensile failure probabilities can be possibly evaluated by not only establishing limit-state function withthe predefined critical values but also performing Monte Carlo Simulation. Nuclear power plant types similar to the Kori Unit 1, which was shut off permanently in 2017 after the 40-year operation, were herein selected for an illustrative purpose. Consequently, the probability-based performance assessment and prediction of contaminated concrete walls were well demonstrated.

This paper proposes a new visualization method based on cloud technique which uses internal relationship of user correlation and external relation of social network to visualize user relationship hierarchy. The visualization method of this paper can well represent user-focused relationship hierarchy on social networks by a correlation matrix. The importance of a access node reflects into user relationship hierarchy by exploiting external relation of social network. Users of the method can well understand user relationships on account of representing user relationship hierarchy from social networks. In addition, the method use hadoop and hive for distribution storing and parallel processing which the result of calculation visualizes hierarchy graph using D3.

이제 기업별로 분기이익을 발표하는 Earning Season이 돌아왔다. 분기보고에 나타난 실적을 기초자료로 하여 기업들은 내부적으로 자사의 성과를 평가하고 주식시장에서는 투자자들이 기업을 평가하는 기본 자료로 활용하여 온 것이 주지의 사실이라고 할 수 있다. 그러나 엔론사태를 시발로하여 현재까지 꼬리를 물고있는 미국 기업에 대한 회계조작 사건은 기업회계에 대한 신뢰성의 저하를 초래했다. 세계에서 가장 투명한 경영을 한다는 미국의 대기업들이 이러한 사건에 연류되면서 상대적으로 투명성이 의심되는 국가의 기업들은 회계조작과 관련이 없더라도 이러한 악재를 피해 가기는 힘든 것이 현실이다. 회계의 투명성에 대한 신뢰도는 단순한 문제라고 할 수만은 없다. 왜냐하면 회계의 신뢰성에 대한 문제는 기업의 펀드멘탈에 관련된 문제이기 때문이다. 이러한 연유로 자본주의 경제와 불가분의 관계인 회계에 대한 비판과 개혁론이 대두되고 있어 대안적인 방안들이 관심을 끌고 있다. 그 방안의 하나로 지목되는 것이 $''$기업 건전성 지수$''$이다. 기업 건전성 지수는 경영자의 기업관리 및 투자자의 기업평가에 동일하고 유용하게 쓰일 수 있는 재무적 접근법이다. 본 논고에서는 기업 건전성지수에 대한 개념, 활용방안, 회계조정 그리고 지표의 진정한 효과에 대하여 설명하고자 한다.
