  • 본 연구는 벤처중소기업의 조직여유와 기업성과간의 관계에서 기업명성의 매개효과를 분석하기 위한 실증분석 연구이다. 즉 기업규모, 기업연령, 사회적 자본, 환경불확실성을 통제한 뒤, 다음의 세 가지 가설을 검증하였다. 첫 번째 가설은 벤처중소기업의 조직여유(흡수된 여유, 흡수되지 않은 여유)가 기업명성에 유의한 긍정적인 영향을 미치는 지 여부이다. 두 번째 가설은 벤처중소기업의 기업명성이 기업성과에 유의한 긍정적인 영향을 미치는 지 여부이다. 세 번째 가설은 앞에서 분석한 두 가설을 바탕으로 벤처중소기업의 조직여유(흡수된 여유, 흡수되지 않은 여유)와 기업성과간의 관계에서 기업명성이 유의한 긍정적인 매개역할을 수행하는 지 여부이다. 이와 같은 가설을 검증하기 위해 설문지 조사법을 사용하여 유효한 250개의 기업수준 데이터를 확보하여 실증분석에 활용하였다. 실증분석은 SPSS 18.0을 통해 빈도분석, 타당도분석, 신뢰도분석, 상관관계분석, 다중회귀분석을 사용하였다. 이러한 실증분석 결과, 세 가지 의미 있는 결과를 도출하였다. 첫째, 벤처중소기업의 조직여유 유형 중 현금, 유가증권 등과 같은 흡수되지 않은 여유는 기업명성에 유의한 영향을 미쳤으나, 초과인력, 초과설비 등과 같은 흡수된 여유는 기업명성에 유의한 영향을 미치지 않았다. 이는 벤처기업의 특성상 급변하는 환경변화에 유연하게 대응하는 것이 매우 중요하므로, 현금, 유가증권과 같은 흡수되지 않은 여유가 유연하게 전략적으로 활용될 수 있음을 의미한다. 둘째, 벤처중소기업에서의 기업명성은 기업성과에 유의한 영향을 미친다, 이는 벤처중소기업에서도 제품품질, 윤리경영, 사회적 책임(CSR) 등과 같은 기업명성 관리가 기업성과와 기업생존에 영향을 미칠 수 있음을 시사한다. 셋째, 벤처중소기업에서의 기업명성은 조직여유의 유형 중 유연하게 활용가능한 흡수되지 않은 여유와 기업성과간의 관계를 긍정적으로 매개하는 반면, 이미 조직에 흡수되어 버린 흡수된 여유와 기업성과간의 관계는 매개하지 못함이 나타났다. 이는 벤처중소기업에서 흡수되지 않은 여유가 기업명성 관리를 통해 기업의 성과에 영향을 미칠 수 있는 선순환 비즈니스 모델을 제시하고 있다. 마지막으로 본 연구는 제한된 표본의 통계량 분석을 통한 실증분석 연구인만큼 일반화의 한계를 가지고 있지만, 벤처중소기업의 조직여유, 기업명성, 기업성과와 관련된 학문적이며 실무적인 본 연구결과는 후속 연구의 토대를 제공해 줄 수 있기를 기대한다.

  • In general, empowerment is defined as the motivational concept of autonomy and self-efficacy. Recently, the concept of empowerment is applied to improve organizational staff's job satisfaction and organizational commitment in many organizations. Empower-ment in service organizations, i.e., hospitals, has certainly generated more publicity than any other organizations. The objectives of this study are, first, to measure the degree of hospital employees' empowerment using Spreitzer(1995)'s empowerment theory, second, to analyze the causal relationship of organizational and job characteristics, a degree of empowerment, and organizational performance(job satisfaction and organizational commitment), and third, to offer the strategy for the improvement of job satisfaction and organizational commitment. Spreitzer insists that the empowerment is composed of 4 dimensions(meaning, competence, self-determination, and impact). And he argues that various work-related characteristics is a direct cause of empowerment and the indirect cause of job satisfaction and organizational commitment, mediated by the empowerment latent variable. In order to perform this study, data were collected by self-administered questionnaires from hospital employees working in administrative department of 3 university hospitals in Inchon and Kyunggi-Do region. The number of cases is 181(response rate; 86%). The Collected data were analyzed with SPSS Ver. 10.0 and AMOSV Ver. 4.0. First, to test validity of variables, the factor analysis was used. Second, to test reliability, Cronbach's alpha coefficients was calculated. Cronbach's alpha of empowerment variable is 0.8323 showing that there's no problem in regard to the internal consistency. Also the Cronbach's alpha of other variables are 0.8301 of the degree of perceived control, 0.6705 of job characteristics, O.8787 of compensation, 0.9254 of job satisfaction, and 0.8389 of organizational commitment, respectively. Among the questions of job characteristics, two survey questions are deleted due to lowering the reliability. Third, to test multicollinearity and correlation of variables, the correlation analysis was performed. There was no problem of multicollinearity. Finally structural equation modelling (SEM) analysis was conducted to find the causal relationship of organizational and job Characteristics, empowerment, job satisfaction and organizational commitment. The 16 variables are included for the SEM analysis. The major results of this study are as follows: First, in the case of model fitness, the condition of x$^2$ statistic(92.187) is not fully satisfied, but the indices of GFI(0.912), AGFI(0.863), NFI(0.917) and CFI(0.928) are partially satisfied, which needs to upper 0.90. Second, in the result of hypotheses testing, all hypotheses are accepted and have a positive effect in 95% or 99% confidence interval(P<0.05 or P<0.001) except the effect of compensation variable on empowerment(P=0.082). Third, in regard to the direct, indirect, and total effect of variables, the direct effect of perceived control, task characteristics, and compensation on job satisfaction are 0.728, 2.264, 0.328 and on organizational commitment are 0.094, 1.411, 0.418, respectively. Also the indirect effect of perceived control, task characteristics, and compensation on job satisfaction are 0.311, 0.196, 0.028 and on organizational commitment are 0.210, 0.132, 0.019, respectively. Thus, these findings imply that various work-related factors are direct effect of empowerment and indirect effect of result variables, job satisfaction and organizational commitment. Also These results showed that the workplace empowerment is significant mediating factor of employee's job satisfaction and organizational commitment.

  • The increase of the supply of medical service and the increase of hospitals have intensified the competition of hospitals, and the advancement towards internationalization in the opening of medical industry has triggered the infinite competition of medical profession. In addition, the high expectation of customers and quality improvement in the medical care in accordance with the improvement of overall income, and the change of active role of medical consumers according to the popularization and the improvement of rights awareness reflect the customer needs and choice in the medical service. Customers wanted to receive the kind and pleasant service under the up-to-date medical service. Therefore, as a solution, hospital coordinators were emerged for the purpose of smooth treatment and customer satisfaction by generalizing all service of hospital. Accordingly, this thesis attempted to investigate the effect of hospital coordinator education curriculum on the education satisfaction and the quality of medical service. In order to solve the purpose of this study, I, author reviewed the existing literatures, established hypothesis, and verified hypothesis by using the variety of statistics techniques such as reliability, validity, frequency analysis, and regression analysis. The verification of hypothesis is as followings: First, among education training factors of hospital coordinators, the quality of instructor significantly affects the satisfaction of hospital coordinator education training. Second, among training factors of hospital coordinator, the attitude of trainee significantly affects the training satisfaction of hospital coordinator. Third, among education training factors of hospital coordinator, education course significantly affects the training satisfaction of hospital coordinator education. As the qualities of instructor are better equipped, the satisfaction of education becomes higher. It indicates that the education method of instructors is important as an index to represent the qualities of instructor such as the appropriateness of education method, preparation, passion, visual materials, the adequacy of education procession, and specialized knowledge, and it has important effect on the satisfaction of education. In order to enhance the satisfaction of hospital coordinator education, the creation of education environment, making trainee concentrate on the education, is required by appropriately allocating programs, arousing interest in education, based on the attitude of trainee, discussion, and preliminary programs, preparation, ahead of enforcement of education. Fourth, the satisfaction of hospital coordinator education training significantly affects the reliability among the qualities of medical service. Fifth, satisfaction of hospital coordinator education training significantly affects hospitality I kindness among the qualities of medical service. If the education satisfaction of trainee is high, it is effective in the practical application such as dealing with complaints, the duty performance for the patients, and so on in offering the medical service, related to reliability and furthermore, we can find the positive change in the attitude change of medical professions related to the reliability of hospital coordinator. In addition, in the process of offering medical services such as the kind explanation on the duty, rapid response to the customers inquiry, and tidy uniform, practical effect was verified. Sixth, the education training factor of hospital coordinator significantly affects the reliability among the quality of medical service. Seventh, the education training factors of hospital coordinator significantly affect hospitality/kindness. In the education of hospital coordinator, the methods to attract the interest of trainee by emphasizing reliability should be sought and for gaining the practical effect of hospital coordinator education, the sufficient preparation and investigation on the education curriculum should be prerequisite and under this condition, intensified discussion on the instructor and education course is needed. In the design of education course, more education hours and subjects should be allocated in the part of hospitality in order to improve the practical application of hospitality. Therefore, it is meaningful in a sense that this study newly approached the components of hospital coordinator education and the need to modify the quality components of medical service in accordance with the study subjects was raised. This study also finds its meaning in that it provides basic materials for the study of future hospital coordinator education by suggesting the system development model of hospital coordinator education through preliminary study of education training. In addition, this study is meaningful in the aspect that it suggested the direction of education training by showing how the hospital coordinator education training would applied to the hospital coordinator course of the Continuing Education Center at Pusan and Kyungnam National University to some extent. Since all investigation of this study was approached from the side of hospital coordinator, the thoughts of patients who are beneficiaries of medical service, and care givers cannot be identified. Therefore, the satisfaction of patients and care givers through the experience of medical service, which is the essential prerequisite of medical service, should be importantly considered and investigated. Accordingly, The study of comparing and analyzing the views of both patients and care givers should be carried out in the future.

  • The objective of the study are two-fold: one is to explore the relationship between environment, organizational structure, and organizational effectiveness of public health centers in Korea, and the other is to examine the validity of contingency theory for improving the organizational structure of public health care agencies, with special emphasis on public health nursing administration. Accordingly, the conceptual model of the study consisted of three different concepts: environment, organizational structure, and organizational effectiveness, which were built up from the contingency theory. Data were collected during the period from 1st of May through 30th of June, 1990. From the total of 249 health centers in the country, one hundred and five centers were sampled non proportionally, according to the geopolitical distribution. Out of 105, 73 health centers responded to mailed questionnaire. The health centers were the unit of the study, and a various statistical analysis techniques were used: Reliability analysis(Cronbach's Alpha) for 4 measurement tools; Shapiro-Wilk statistic for normality test of measured scores of 6 variables: ANOVA, Pearson Correlaion analysis, regressional analysis, and canonical correlation analysis for the test of the relationships and differences between the variables. The results were. as follows : 1. No significant differences between forma lization, decision-making authority and environmental complexity were found(F=1.383, P=.24 ; F=.801, P=.37). 2. Negative relationships between formalization and decision-making authority for both urban and rural health centers were found(r=-.470, P=.002 ; r=-.348, P=.46). 3. No significant relationship between formalization and job satisfaction for both urban and rural health centers were found (r=-.242, P=.132, r=-.060, P=.739). 4. Significant positive relationship between decision - making authority and job satisfaction were found in urban health centers (r=.504, P=.0009), but no such relationship was observed in rural health centers. Regression coefficient between them was statistically significant($\beta=1.535$, P=.0002), and accuracy of regression line was accepted (W=.975, P= .420). 5. No significant relationships among formalization and family planning services, maternal health services, and tuberculosis control services for both urban and rural health centers were found. 6. Among decision-making authority and family planning services, maternal health services, and tuberculosis control services, significant positive relationship was found between de cision-making authority and family planning services(r=.286, P=.73). 7. A significant difference was found in maternal health services by the type of health centers (F=5.13, P=.026) but no difference was found in tuberculosis control services by the type of health centers, formalization, and decision-making authority. 8. A significant positive relationships were found between family planning services and maternal health services and tuberculosis control services, and between maternal health services and tuberculosis control services (r=-.499, P=.001 ; r=.457, P=.004 ; r=.495, P=.002) in case of urban health centers. In case of rural health centers, relationships between family planning services and tuberculosis control services, and between maternal health services and tuberculosis control services were statistically significant (r=.534, P=.002 ; r=.389, P=.027). No significant relationship was found between family planning and maternal health services. 9. A significant positive canonical correlation was found between the group of independent variables consisted of formalization and de cision-making authority and the group of dependent variables consisted of family planning services, maternal health services and tuberculosis control services(Rc=.455, P=.02). In case of urban health centers, no significant canonical correlation was found between them, but significant canoncial correlation was found in rural health centers(Rc=.578, P=.069), 10. Relationships between job satisfaction and health care productivity was not found significant. Through these results, the assumed relationship between environment and organizational structure was not supported in health centers. Therefore, the relationship between the organizational effectiveness and the congruence between environment and organizational structure that contingency theory proposes to exist was not able to be tested. However decision-making authority was found as an important variable of organizational structure affecting family planning services and job satisfaction in urban health centers. Thus it was suggested that decentralized decision making among health professionals would be a valuable strategy for improvement of organizational effectiveness in public health centers. It is also recommended that further studies to test contingency theory would use variability and uncertainty to define environment of public health centers instead of complexity.

  • The concept of parish nursing began in the late 1960s in the United States when increasing numbers of churches employed registered nurses (RNs) to provide holistic, preventive health care to the members of their congregations. Parish nursing role was developed in 1983 by Lutheran chaplain Granger Westberg, and provides care to a variety of church congregation of various denominations. The parish nurse functions as health educator, counselor, group facilitator, client advocate, and liaison to community resources. Since these activities are complementary to the population-focused practice of community health' CNSs, parish nurses either have a strong public health background or work directly with both baccalaureate-prepared public health nurses and CNSs. In a Midwest community in U.S.A., the Healthy People 2000(1991) objectives are being addressed in health ministries through a coalition between public health nurses and parish nurses. Parish nursing is in the beginning state in Korea and up untill now, there has been no research was conducted on concrete role of korean parish nurses. The main purpose of this study was to identify, classify and analyze activities of parish nurses. The other important objective of this study was to establish an effective approach and direction for parish nursing and provide a database for korean parish nursing model through analysis and' classification of the content of the nursing record which included nursing activities. This study was a descriptive survey research. The parish nurses were working in churches where the demonstration project developed on parish nursing. The study was done on all nursing records which were working in churches where the demonstration project developed on parish nursing. The study was done on all nursing records which were documented by parish nurses in three churches from March, 1995 to February, 1996. Namsan, Taegu Jeei and Nedang presbyterian churches in Taegu and Keimyung nursing college incooperated together for the parish nursing demonstration project. The data analysis procedure was as follows: First, a record analysis tool was developed and second, the data was collected, coded and analyzed, the classification for nursing activities was developed through a literature review, from which the basic analysis tool was produced and cotent validity review was also done. The classification of the activities of parish nurses showed 7 activitity categories. 7 activity categories consisted of visitation nursing, health check-ups, health education, referring, attending staff meetings, attending inservices and seminar, volunteers coordinating. The percentage of activities were as follows: Visitation nursing(A: 51.6%, B: 55%, C: 42.6%) Health check-ups(A: 13.5%, B: 12.1%, C: 22.3%) Health education(A: 13.5%, B: 13.2%, C: 18.2%) Referring(A: 1.4%, B: 4.2%, C: 2.4%) Attending staff meeting(A: 18.8%, B: 13.0%, C: 12.2%) Attending inservices and seminar(A: 1.5%, B: 2.2%, C: 2.1%) Volunteers coordinating(A: 0.3%, B: 0.4%, C: 0.0%) To establish and develope parish nursing delivery network in Korea, parish nurses role, activities and boundaries of practice should be continuously monitored and refined every 2 years. Also, It is needed to develope effective nursing recording system based on the need assessment research data of various congregation members. role, activities and boundaries of practice and arrangement of the working structure, continuing education, cooperation with community resources and structuring and organizing parish nursing delivery network. Also, It is needed to develope effective nursing recording system based on the need assessment research data of various congregation members.

  • 개념적 모델링(conceptual modeling)은 정보시스템 개발에 있어서 중요한 역할을 수행한다. 그럼에도 불구하고 이를 성공적으로 수행하기 위해 어떠한 방법을 채택해야 하고 그 결과를 어떻게 평가해야 할 것인지에 대한 이론적 성과는 충분하지 않다. 부분과 전체에 대한 개념적 모델링을 평가하기 위해 온톨로지 이론을 도입한 최근의 연구, "Representing Part-Whole Relations in Conceptual Modeling : An Empirical Evaluation"(Shanks et al., 2008)은 개념적 모델링 평가에 실험법을 도입했다는 긍정적인 측면에도 불구하고 비판에 직면했다. 또한 이에 대한 반대 의견이 제시되면서 개념적 모델링을 연구하거나 실무에 활용하려는 사람들에게 혼란을 초래하고 있다. 본 연구는 Bunge-Wand-Weber 온톨로지의 이론적 배경과 성과를 검토하고 논쟁에서 제외된 부분과 전체에 관한 이론적 논의를 추가하여 과연 Shanks et al.의 연구에 대한 비판이 타당한 것인지 살펴본다. 이들 연구에 대한 비판이 주로 실험적 방법의 오류를 지적한 것과 비교하여 본 연구는 Shanks et al.의 연구가 번지(Bunge) 온톨로지를 잘못 활용하고 있으며, 패러다임의 문제라는 지적은 그 근거가 확실하지 않으며, 부분과 전체에 관한 연구개념의 타당성을 확보하지 않았음을 밝혔다. 본 논문을 통해 우리는 Shanks et al.의 연구는 실증적 타당성에 대한 문제뿐만 아니라 기존의 온톨로지 개념들을 적절히 활용하지 않았고 결과적으로 부분-전체에 관한 개념적 모델링 이론에 기여하기보다는 서로 다른 모델링 패턴 간의 단순한 비교에 그쳤다는 점을 주장한다.

  • 블로그, 페이스북, 트위터와 같은 SNS(Social Network Service)는 유저와 포스트를 노드로, 유저와 포스트, 포스트와 포스트, 또는 유저와 유저 사이에 형성되는 다양한 관계를 링크로 하는 그래프로 표현될 수 있다. 본 논문은 이러한 그래프 구조를 분석하여 다른 유저들의 생각과 행동에 영향을 미치는 영향 유저를 선별하는 방법에 대해 논한다. 기본적인 패러다임으로 기존의 투표성 개념이 아닌, 다양한 시맨틱 웹 자원의 중요도를 평가하기 위해 제안된 상호작용성 개념을 초기 SNS의 하나인 블로고스피어의 영향력 평가에 적용함으로써, 여러 모의 실험을 통해 그 타당성과 적용 가능성을 입증하였다. 모의 실험은 각 대안이 제공하는 결과의 타당성 정도에 따라 성능을 비교 분석할 수 있는 네트워크 모형을 디자인하여 사용하였다. 또, 이러한 네트워크 모형에 대한 링크 가중치 튜닝의 결과 변화를 살펴봄으로써, 가중치 조합의 차이에서 발생하는 실험 오차를 줄이고, 실제 적용의 용이함을 비교 분석하였다. 부가적으로, 스팸 필터링 목적에서 포스트 컨텐츠 점수를 링크 구조 기반 방법 안에 포함시킬 수 있는 방법도 제안하였다. 본 연구는 SNS 영향유저 선별에 대한 연구의 출발점으로서, 다음과 같은 점에서 기존 연구와 구별된다. 첫째, 스크랩, 댓글, RSS, 친구 등 기존 연구에서 유의미한 속성으로 간주했지만, 그래프 기반 방법으로 함께 고려할 수 없었던 다양한 영향력 속성들을 종합적으로 반영할 수 있는 그래프 기반 영향력 평가 프레임웍을 제시한다. 둘째, 이 프레임웍은 영향력이 높은 개체들과 상호작용하는 개체가 영향력이 낮은 개체들과 상호작용하는 개체보다 높은 영향력을 갖게 되는 일반적인 현상을 구현할 수 있는 양방향성을 반영한다. 셋째, 영향력 평가 면에서 다른 사람들의 추종액션을 유발한 정도를 가장 중요한 요인으로 고려하여, 일련의 참조관계에 대해 기존의 페이지랭크나 HITS(Hypertext Induced Topic Selection)와는 다른 관점에서 접근하였다.

  • 국내 건설산업에서 생산성 정보의 필요성과 그 활용에 대한 중요성 인식에도 불구하고, 현장 단위의 공사계획 시 효과적인 피드백을 통한 생산성 정보관리가 미흡한 실정이다. 공사계획의 신뢰성을 향상하기 위해서는 생산성 정보의 효과적인 활용이 요구되지만, 현장에서는 공사계획을 관리자의 경험 및 직관에 의존하고 있다. 생산성 정보가 효과적으로 관리되지 못하는 이유는 생산성 정보의 관리를 위한 추가 인력투입이 어렵다는 점, 기존의 생산성 정보가 새로운 프로젝트에 적용되기 어렵다는 점 등 때문인 것으로 파악되었다. 이러한 문제의 해결방안을 제시하기 위해서 선행연구조사 및 면담조사를 하였고 그 결과 새로운 시스템이 필요하다는 사실을 확인하였다. 새로운 시스템의 요구사항으로는 최소화된 업무, 한정된 정보관리범위, 정보의 분류, 정보의 피드백, 생산성 저하요인의 고려 등이 있다. 본 연구에서는 상기 내용을 바탕으로 생산성 저하요인 및 생산성 정보의 관리가 가능한 시스템의 프레임워크를 제안하였다. 이 시스템은 사용자 접근성이 좋은 SketchUp 소프트웨어를 활용하여 프로그램의 활용에 따른 추가인력의 투입이나 업무량 증가를 최소화할 수 있도록 하였다. 제안한 시스템은 준비단계, 입력단계, 처리단계, 출력단계의 총 네 단계의 과정을 통해서 정보를 입력하여 처리하고 출력하도록 하였다. 입력한 시공정보는 건축공사 표준시방서에 기재된 내용을 참고로 구성한 Task Breakdown Structure (TBS)와 Material Breakdown Structure (MBS)를 통해서 분류되어 생산성 정보로 변환되도록 하고, 변환된 정보를 그래픽으로 화면에 출력하도록 하여 사용자는 이를 활용해 해당 현장에서의 생산성 정보를 활용할 수 있도록 하였다. 본 연구에서 제안한 생산성 정보관리 시스템을 K 사옥 공사현장에 대입하여 현장적용 가능성 및 정보 활용성 측면에서 검증하였고, 사용성 및 적용 가능성에서 매우 긍정적인 결과와 정보 활용에 따른 이득이 있을 것으로 예상되었다. 본 시스템을 활용할 경우 생산성 정보를 활용한 공사계획이 가능할 것이고 추후 정보가 지속해서 누적될 경우, 본 연구의 기대효과는 더욱 높아질 것으로 사료된다.

  • Numerous research reports have substantiated the role of stressful life events in relation to the onset of health changes. The relationship tends to hold across different age groups. Theoretically, adolescence has been considered a developmental crisis period of great stress, impoverished coping skills and high vulnerability to biological, social and psychological demands. The research problem addressed by this study was to examine the relationships between stressful life events and health symptom patterns, and the effect of two variables, coping and social, support, theoretically considered to mediate the relationship between stress and health symptoms in adolescents. The following five hypotheses were tested in this research : 1. Health symptoms are positively related to stressful life events in adolescents, 2. Health symptoms are negatively related to coping in adolescents, 3. Health symptoms are negatively related to social support in adolescents, 4. When coping is controlled, the relationship between health symptoms and stressful life events will decrease, and 5. When social support is controlled, the relationship between health symptoms and stressful life events will increase. The study subjects consisted of 1090 high school students of the metropolitan city of Seoul. The following sampling procedure was used : 1. Of the 169 high schools in nine school administrative districts in the city, a proportional sample of ten schools was selected. 2. One class from each of the freshman and sophomore was randomly selected and all the students who were in the sampled class were used as the study sample. The study was limited to freshman and sophomore adolescents, aged 15 to 18(mean=16.6). Of the 1090 subjects 688(63%) were boys and 402(37%) were girls. An Adolescent Inventory of Stressful Life Events, a Health Symptom Questionnaire and an Adolescent Coping Inventory were adapted for this study. The Norbeck Social Support questionnaire was utilized to collect the data on perceived social support. Five high school teachers in the areas of school health and counselling reviewed the items of each questionnaire for content validity. A pilot study was undertaken to ascertain reliability. Fifty three high school students responded to the questionnaires and gave their opinions on the items. For stressful life events, health symptoms, coping, and social support, the Cronbach's alpha's on the study were .70, .94, .77, and .76, respectively. Research assistants attended all the sampled classes with the school proctor to explain the purpose and procedures of the study to the students. The questionnaires along with a ballpoint pen were distributed to the students who were asked to complete each item. The research assistants left the ballpoint pen with the students as a gift for their cooperation. An average of 50 minutes was required to complete the questionnaires. Using an SPSS, the first, three hypotheses were tested using Gamma, a measure of association for ordinal variables. Partial gamma was used to test the fourth and fifth hypotheses. Patterns of elaboration described by Babbie were selected to interpret the relationship of the three variable analyses. The significance of gamma was determined by Chisquare at a .05 level of significance. There was a positive relationship between health symptoms and stressful life events(Gamma=.35, p=.000). Thus the first hypothesis was supported. Unexpectedly, coping was positively related with health symptoms(Gamma=.13, p=.000). That is, the higher the coping levels, the greater number of health problems. The third hypothesis, the higher the level of social support, the fewer the health symptoms, was not accepted in this adolescent study group. When coping was controlled, under the condition of low coping the association between health symptoms and stressful life events increased significantly to a partial gamma of .39, and under the condition of high coping it was .30. According to the elaboration model, when one partial relationship is the same or greater than the original and the other is smaller, the control variable should be considered to be specifying the conditions. When social support was controlled the relationship between stressful life events and health symptoms increased under the condition of low social support, but with high social support, the relationship decreased. Both partial gamma were statistically significant at .05 level(.43 and .26 relatively). It can be interpreted that stressful life events are strongly and positively related to health symptoms under the condition of low social support, however this relationship can not be expected with high social support. Thus, the last two hypotheses were conditionally sustained. In this study, the relationships between stressful life events and health symptoms, and the specified me diating roles of coping and social support were found to have statistical interaction. This finding supports the theoretical position of this study. It suggests that stressful life events would create high susceptability to biological social and psychological health symptoms and coping and social support buffering the relationship between stressful life events and health symptom. The findings of this study have implications for nursing practice. When adolescents are confronted with non-developmental life events that are perceived as stressful, nurses should recognize the evidence of the stress-buffering effect of coping and social support on health symptoms and utilize the diverse sources of social support that are readily available to adolescents.
