  • 국제통상을 하는 기업은 위험 선호도에 따라 금융시장을 통해 외화자산 혹은 외화부채의 헷징(hedging)을 목적으로 파생금융상품을 쉽게 구매할 수 있다. 파생금융상품 시장은 투자와 헷지의 필요에 따라 급속도로 성장해왔다. 기업은 금융 파생금융상품을 통해 환위험 관리를 하면서 위험을 헷징한다. 기초자산을 헷징할 때는 환노출 완화전략으로 헷징이 효과적일 수 있다. 하지만 파생상품을 통한 이익에 대한 욕심과 예상치 못한 환율 변동이 발생할 때 기업에 상당한 위험을 초래할 수도 있다. 본 논문은 환위험을 다루는 파생상품에 내재된 구조적인 위험을 시스템다이내믹스 관점에서 분석하고 있다. 대표적인 파생금융상품인 KIKO는 구조적인 위험 요인 때문에 금융위기에 크나 큰 손실을 끼쳤다. 본 논문에서는 KIKO의 구조적 위험 요인을 모델링하고 실제 사례를 통해 검증하여 파생금융상품의 시스템 구조를 파악하고 내재되어 있는 구조적 위험을 밝혔다.

  • The purposes of this study were to provide evidence concerning the effects of Emotional Leadership and examine the impacts of Emotional Leadership on employee-related variables which were 'job satisfaction', 'organizational commitment', 'organizational performance', 'turnover intention'. A survey was conducted from August 23 to November 3, 2005 to collect data from kitchen staff(N=611). Statistical analyses were completed using SPSS Win(12.0) for descriptive analysis, reliability analysis, factor analysis, t-test, correlation analysis, cluster analysis and AMOS(5.0) for structural equation modeling. Kitchen staffs gave high point to their leader in the Emotional Leadership competence 'Optimism: seeing the upside in events' and 'Adaptability: flexibility in handing change' and gave lower point in the Emotional Leadership competence 'Inspirational leadership: guiding and motivating with compelling vision'. Employees' job satisfaction on 'coworker' were relatively high. However, the extents of satisfaction on 'payroll', 'promotion', 'work environment' were relatively low. The organizational commitment score was higher at 'loyalty' factor than 'commitment' factor. the test of hypothesis using structural equation modeling found that Emotional Leadership produced positive effects on job attitude and job performance. In conclusion, this study has identified that the Emotional Leadership effects on their organizational performance and attitudes toward their job.

  • The application of Big Data has been introduced to the Korean fashion industry; however, the literature has not yet investigated how well high technologies are being perceived and adopted by the practitioners of fashion companies. Recognizing the lack of research, the current research explores how big data analysis has been adopted by fashion practitioners based on the Technology Acceptance Model (TAM) that considers the effect of organizational characteristics (i.e., innovation, slack, and IS infra maturity). First, all TAM relationships were accepted as significant; however, the effect of perceived ease of use on the attitude toward big data was greater than perceived usefulness. Regarding organizational characteristics, while organization innovation had positive impacts on perceived usefulness as well as perceived ease of use, organization slack did not show significant and positive influence on perceived ease of use only. On the other hand, IS infra maturity had a negative effect on perceived usefulness while it did not have any significant impact on perceived ease of use. Finally, the level of perceived usefulness is decreasing as the IS infra of the fashion organization becomes more mature. With the results, the study suggested that fashion industry needs more education on the usage of big data analysis systems and development in related analysis tools.

  • Koreans have emphasized education as the primary means to reconstruct our country means to reconstruct our country after two catastrophic events-the Japanese occupation and the Korean War(1950-1953). A Strong belief- in education coupled with sheer deter-mination spurred the period of industrial and eeonomic development that started in the early 1970-'s. The "can-do" attitude of the general public was matched and aided by small S & T communities. Scientists and engineers provided the neeessary expertise to manufacture goods and process the many raw materials imported from overseas. After nearly three decades of reconst-ructing our completely devastated country, Korea has become a modern, cosmo-politan, fast-paced and dynamic country. In order to further increaser our manufac- turing capabilities and double the per-capita income by the beginning of the 21st century, we must improve productivitiy and encourage creatitivity in all sectors of our country. The S & T community's efforts in research and development. education, and interna-tional cooperation will be invaluable in determining our direction and reaching these goals. The general public is eager to peacefully unite our foreign powers since 1945. Toward that end. members of the S & T community are willing to coope-rate with our north Korean counterparts in all areas of S & T with the exception of defense related endeavors. Establi-shing scientific ties with north Korea will result in mutual economic benefit and greater regional stability in East Asia. In particular. scientists and manu-facturers in each province are eager to initiate cordial and professional relation-ships with north Korea in the hopes of securing these benefits. The Korean Federation of Science and Technology Societies(KOFST) has played an important role both in developing S & T policies, and in gostering the frowty of S & T societies. A non-governmental umbrella organization composed of over 251 professional societies, KOFST facili-tates the transfer of research outcomes and technology from research institutions to the various industries. KOFST also seeks to increase cooperation between the countries of the Pacific Rim. As evidence of that, we have pursued joint research and industrial ventures with China. Established projects include those on environmental conditions in the Yellow Sea, and improvement of aircraft manufacturing, telecommunica-tion equipment, and agricultural produ-cts. Increased cooperation between the Pacific Rim countries, particularly in S & T, would foster social and economic development for the region as a whole.

  • Stroke is known as a detrimental disease that leaves serious sequelae. The stroke patients suffer from limitations of physical and social activities. The patients try to adapt themselves to the limitations in order to achieve rehabilitation. This study was performed to clarify the lived experience of rehabilitation from the stroke patients. In collecting data for this study, in-depth personal interviews were made by a researcher from February to April in 2001 at rehabilitation clinics and physical therapy centers locate in Iksan city. The methodological approach was van Manen's hermeneutic phenomenological methodology in order to understand the meaning and nature of stroke patients' experiences in rehabilitating their physical limitations. Collected data were analyzed with phenomenological way of study that was develope by van Manen. The 8 patients who agreed to participate in this research were inter viewed by researcher under the private and comfortable environment. Personal interviews were done three or five times per each patients and each interview took 70 to 90 minutes. The statements were analyzed and finally revealed three essential themes : Theme 1 - Desperateness to achieve freedom again Theme 2 - Seizing hope of recovering Theme 3 - Seeking support from family members, relatives and friends Based on these themes, stroke patients' rehabilitation experience are described as following. The stroke patients have strong desire to achieve freedom again in order to escape from social isolation. The stroke patients want to go back to the state of their previous health state. The stroke patients strongly try to do anything for their recovering and also to have positive thinking. In the other hand, they feel pity for themselves through desperation, fear, sorrow, and self-pity. The stroke patients have dissatisfaction about neighbors' rumor and attitude toward themselves. The stroke patients have experiences to rely on neighbors' support seeking a warm word of consolation. This research showed us that van Manen's hermeneutic phenomenological methodology leads us to understand stroke patients' rehabilitation process more comprehensibly. Based on this research, it is suggested that further studies provide a foundation for the development of a rehabilitation theory for Korean stroke patients.

  • Objectives: The purpose of the study was to test the applicability of the Theory of Planned Behavior(TPB) to Korean adult smokers in order to obtain an enhanced understanding of their smoking-cessation intention and to establish strategies for effective smoking-cessation interventions at the community clinic. Methods: The data came from a survey that was conducted on adult male smokers who visited the smoking-cessation clinic at H community clinic in Korea from January to November in 2006 (N=434). Included in the survey were questions asking core variables and salient belief variables dictated by TPB. A structural equation model was established using TPB and data were analyzed to examine the applicability of the theory to the understanding of the structure of variables leading to intention. Results: The analysis of the structural model revealed that the study model was statistically significant(p<.001), suggesting the high validity of TPB in explaining the structure of the data. Among the relationships in the model, negative behavioral beliefs were not significant(p>.05), and negative control beliefs and subjective norm were significant(p<.05) but not as highly as other variables in the model(p<.001). Conclusion: TPB was useful in understanding smoking-cessation intention of smokers who visited community clinic to stop smoking. More specific strategies for counseling and education need to be developed to enhance attitude and perceived behavioral control (self-efficacy) toward smoking-cessation intention, such as emphasizing health benefits of quitting smoking, and eliciting values and life principles that can help increase the intention to stop smoking.

  • 환경오염이라는 인류의 총체적 위기는 인간 중심적 패러다임을 인간과 자연의 공존을 목표로 하는 생태학적 패러다임으로 변화시켰고, 이에 따라 디자이너 역시 인류의 과제인 환경문제 해결에 동참하지 않을 수 없게 되었다. 이러한 사회적 책임과 디자이너 자신의 윤리적 책임은 디자인 방향을 환경을 위한 디자인(Design For Environment)으로 전환하게 하였다. 본 연구는 디자인을 통한 환경 문제 해결이라는 측면에서 그 하나의 실마리를 제공하는 것에 그 목적이 있다. 즉, 제품의 조형에서 내구적 속성을 파악하여 이를 제품에 부가함으로써, 경제적 손실과 환경오염을 줄이는데 기여할 수 있을 것이라는 것이다. 제품의 형태를 결정짓는 디자이너의 입장에서 제품 조형의 내구적 속성을 파악하여 이를 제품에 부여한다는 것은 제품의 수명(Product Life Cycle)을 연장시키는 데 도움을 줌으로써, 제품의 폐기를 유보시킬 수 있을 뿐 아니라 제품이 제 수명을 다하기도 전에 새로운 형태의 제품에 밀려 폐기되는 일을 감소시켜 과잉 생산에서 오는 에너지 낭비와 자원의 소모를 막고, 오염물질의 방출과 쓰레기를 줄여 환경오염을 최소화시킬 수 있는 것이다. 이것은 기본적으로 기업의 과도한 경쟁 의식에 의한 무분별한 제품개발과 소비자의 소비 지향적인 태도에 반발하는 것이다. 이 가정 위에서 제품 조형의 내구적 속성을 밝히는 것이 이 논문의 궁극적 목표라 하겠다.

  • Purpose : The purpose of this study was to investigate the effects of stresses to female university students and their habits of dealing with stresses through drinking alcohol and smoking. Methods : Subjects, 313 students, were selected through convenience sampling method from the 2 four-year universities in Chonbuk and Chonnam province from May to June, 2005. Data were collected through the structured questionnaires that include general characteristics, Quantity Frequency methods, the number of cigarette per day, campus stress scale, and stress coping style scale, and they were analyzed by Cronbach' alpha, descriptive statistics, ANOVA and t-test by using SPSS/PC+ program. Results: In this study, 80% of subjects have drunk alcohol. The mean frequency of drinking alcohol per month was 4.68 times and the mean number of alcohol consumption amount per drinking 6.16 glasses. The rate of smoking was 13.7%, and the mean number smoking cigarette per day in the previous month was 12.4. The mean score of stress was 2.20. Among 8 sub-factors of stress, study related stress scored highest among the sub-factors. The mean score of coping styles was 2.50. Among 4 coping styles, hopeful thought was mostly used. Among stresses, the concern of one's future affected her drinking habits. Faculty relationship, academic problem, and value affected smoking habits. Hopeful thought comes out to affect smoking, while drinking, perceived health status, and practice time showed no relationship with coping style. Conclusion: Based on the results, developing a life stress counseling program and effective coping program for women's university students is imperative, especially for those of who show passive attitude toward stress and solve it emotionally instead of using problem-oriented methods. Also, it will be necessary to study further nursing intervention to curb university females' drinking alcohol and smoking.

  • Objectives: To investigate how dental hygienists who have never used a digital oral scanner perceive the impression acquisition and evidence needed for prosthesis planning by using a digital oral scanner. Methods: From July 1, 2017 to December 31, 2017, subjects from Daegu, Gyeongsangbuk-do, Korea, were selected. The purpose of the study was described to dental hygienists who had never used a digital intraoral scanner. Questionnaires were distributed to the students selected. Of the 137 questionnaires distributed, 93 were used in the analysis after excluding 44 completed questionnaires that had errors or missing answers. Results: Of the respondents, 33.7% (36/93) were aged ${\geq}30$ years, 68.8% graduated from a 3-year vocational college course, 33.5% were aged ${\geq}33$ years, and 61.3%. At present, our center has the largest number of clinics (92.5%). The difficulty of impression taking using the digital oral scanner significantly differed (p<0.05) according to age and current occupation (p<0.05). Impression taking using a digital oral scanner significantly affected the present workflow of dental hygienists and their interest in sharing information about future use of digital oral scanner (p<0.01). Conclusions: If more routes are available to access digital intraoral scanners and more systems are developed for clinical use, the digital intraoral scanner could become digitized in the dental system; thereby, the existing impressions could be replaced with digitized impressions. With digital intraoral scanners, the expansion of the business of dental hygiene can be expected.
