According to technology acceptance model(TAN) which is one of the most important research models for explaining IT users' behavior, on intention of using IT is determined by usefulness and ease of use of it. However, TAM wouldn't explain the performance of using IT while it has been considered as a very good model for prediction of the intention. Many people would not be confirmed in the performance of using IT until they can control it at their will, although they think it useful and easy to use. In other words, in addition to usefulness and ease of use as in TAM, controllability is also should be a factor to determine acceptance of IT. Especially, there is a very close relationship between controllability and ease of use, both of which explain the other sides of control over the performance of using IT, so called perceived behavioral control(PBC) in social psychology. The objective of this study is to identify the relationship between ease of use and controllability, and analyse the effects of both two beliefs over performance and intention in using IT. For this purpose, we review the issues related with PBC in information systems studies as well as social psychology, Based on a review of PBC, we suggest a research model which includes the relationship between control and performance in using IT, and prove its validity empirically. Since it was introduced as qa variable for explaining volitional control for actions in theory of planned behavior(TPB), there have been confusion about concept of PBC in spite of its important role in predicting so many kinds of actions. Some studies define PBC as self-efficacy that means actor's perception of difficulty or ease of actions, while others as controllability. However, this confusion dose not imply conceptual contradiction but a double-faced feature of PBC since the performance of actions is related with both self-efficacy and controllability. In other words, these two concepts are discriminated and correlated with each other. Therefore, PBC should be considered as a composite concept consisting of self-efficacy and controllability, Use of IT has been also one of important areas for predictions by PBC. Most of them have been studied by analysis of comparison in prediction power between TAM and TPB or modification of TAM by inclusion of PBC as another belief as like usefulness and ease of use. Interestingly, unlike the other applications in social psychology, it is hard to find such confusion in the concept of PBC in the studies for use of IT. In most of studies, controllability is adapted as PBC since the concept of self-efficacy is included in ease of use explicitly. Based on these discussions, we can suggest perceived use control(PUC) which is defined as perception of control over the performance of using IT and composed of controllability and ease of use as sub-concepts. We suggest a research model explaining acceptance of IT which includes the relationships of PUC with attitude and performance of using IT. For empirical test of our research model, two user groups are selected for surveying questionnaires. In the first group, there are freshmen who take a basic course for Microsoft Excel, and the second group consists of senior students who take a course for analysis of management information by Excel. Most of measurements are adapted ones that have been validated in the other studies, while performance is real score of mid-term in each class. In result, four hypotheses related with PUC are supported statistically with very low significance level. Main contribution of this study is suggestion of PUC through theoretical review of PBC. Specifically, a hierarchical model of PUC are derived from very rigorous studies in the relationship between self-efficacy and controllability with a view of PBC in social psychology. The relationship between PUC and performance is another main contribution.

본 연구는 팬데믹 시기 비대면 비만관리 프로그램의 개발하여 적용한 후 그 효과를 평가하고자 하였다. 근거기반 비대면 비만관리 프로그램 개발은 Intervention Mapping Protocol (IMP)를 이용하였다. 프로그램의 운영은 대구광역시 시민건강 놀이터 온라인 채널을 통해 참여를 신청한 과체중 및 비만 성인 48명을 대상으로 2020년 9월 14일부터 11월 13일까지 8주 동안 실시하였다. 효과평가는 프로그램 전·후 자가 신체 계측 측정, 건강행태 설문 및 만족도 설문 분석을 통해 평가하였다. IMP를 통한 중재 프로그램의 개발은 IMP 6단계의 과정을 적용하였고 1단계 요구사정은 간호·영양·운동 교육자 면담을 통해 대상자 선정 기준, 프로그램 운영 방법 등을 결정하였다. 2단계 목표 설정은 비만관리를 위한 행동 변화목표 3가지를 설정하였고 3단계에서는 건강·영양·운동 영역별 근거기반으로 건강행태 변화를 위한 중재 방법 및 수행 전략을 선택하였다. 4단계 프로그램 설계는 8주 동안 대상자의 수행 과제 및 인증방법 등 구체적으로 프로그램을 설계하였고 5단계에서는 개발된 프로그램의 실행 계획을 작성하고 실제 적용하였으며 6단계에서는 적용한 프로그램의 효과를 평가하였다. 비대면 비만관리 프로그램 참여 전·후 신체 계측 값을 통한 효과 평가 결과 평균 체중은 1.2kg이 감량되었고, 허리둘레는 3cm가 감소하였으며, 체질량지수(BMI)는 0.8kg/m² 감소하였다(p<0.05). 대상자의 건강행태 설문을 통한 효과 평가 결과는 프로그램 참여 전·후 1일 평균 섭취 열량, 과일 섭취, 걷기 운동 실천 등의 생활습관이 긍정적으로 개선되었고 통계적으로 유의한 차이가 있었다(p<0.05). 프로그램 과정 평가를 위한 만족도는 4.57±0.63점으로 높게 나타났다. 본 연구 결과에 근거하여 비대면 비만관리 프로그램은 팬데믹 시기에 시간과 장소의 제약 없이 전문가의 개별상담과 자가 신체 계측 측정 및 기록을 통한 대상자의 적극적인 참여가 가능한 프로그램으로 지역사회 성인 대상 비대면 비만 관리에 유용하게 활용될 수 있을 것이다. 그러나 비대면 비만관리 프로그램은 앱 사용 등 대상자의 나이에 따라 비대면 프로그램 참여에 일부 제약이 있다. 따라서 본 연구로 개발된 비대면 프로그램과 함께 필요시 대면 프로그램의 병행을 제언하며, 추후 장기적인 프로그램의 운영에 따른 효과 평가를 검증하기 위한 지속적인 연구들이 필요할 것으로 사료된다.

Every country in the world has been trying to expand the basic health right for the peoples as W.H.O has established the goal 'health for AU' by the year of 2000. Related to this goal, our government authority has establish the policy 'the insurance of health for all' into effect from July 198\). Recently hospitalshave been making a ceaseless effort for the plan for the rationalization of its management the academic World is making it a subject of discussion by doing the secure of manpower at a resonable level and the increase of productivity by the manpower. As a result of the efforts the study was established to secure the numbers of nursing manpower at a resonable level and use the unskilled persons at the utilizing field and seek the possible area of their activity for more efficient service through the investigation of ablity of simple nursing activities of regiestered nurses and nurse aides for rational function according to the educational levels and talents. The method of study was established by the registered nurses and nurse and nurse aides(R.N 229, N.A 226) who are working in 15 hospitals with over 200 beds. This surrey was conducted from Mar 29, 1989 to April 8, 1989. The method to test the degree of importance, difficulties, and the abillity of performance of a simple nursing activities was classified into 35 activities on the basis of references on this field. The degree of importance was composed from point l(Not so important) to 5(Very important). the degree of difficulties. was composed as follows; very easy - Point 1 very difficult and complicated - Point 5. and the ability of performance was composed from point 1 to 5. The materials gathered through the survey were analyzed with frequency, mean standard deviation, percentage. t-test, Anova, pearson's coefficient of correlation, stepwise multiple regression. factor analysis, discriminant analysis. The obtained results are summarized as follows: 1. The recognition values of the simple nursing activities of each group of registered nurse and nurse aides show; The degree of importance; 4.04 and 4.26 The degree of difficulties; 2.72 and 2.94 The ability of performance; 2.07 and 2.38 The brief summary shows there are little differences between who two groups the simple nursing activities turned out to be easy and simple work. 2. Regardless of the degree of importance, and difficulties, the ability of performance the important in fluencing of the degree of the simple nursing activities between the registered nurses and nurse aides was the order of educational level, hospital career, working career in wards and ages of the registered nurses and ages and hospital creer of nurse aides. The result was that the simple nursing activities could easily be familiar through the training of their working environment and period of experience. 3. Among the 35 simple nursing activities the items capable of resonable entrusting to the nurse aides are 5 that is helping bed-bathing, 8itz Bath, using bed pan, care while delivering patient, accompaying patient when visitor's check. There wasn't and differences between RN and nurse aides in performing the above 5 items. In anywhere. so we can say obviosuly that this nursing activities should be performed under the nursing system of which chief of nurse are supposed to supervise nurse aides as a possible function to be entrusted. In view of the above mentioned results, therefore, this partial functional job of the simple nursing activities can able be entrusted to the nurse aides through the regular training course. In case of these functional activities could be entrusted under, the responsibility of registered nurse, we can able suggest to for that there are the following advantages: 1.. In the nursing activities-affairs, the qualified guarantee of the nursing services can be kept and increased or promotoed with accommodation of the required nursing service and roles being expanded presently. 2. In the productivity of the hospital manpower, therefore, we have comt to view and consider in favourly that when an automational administration times would be come in the near future time to hospital affairs as a reality, to utilize the existing nures aides is better rather than investing so as to develop the other source manpowers or seek its for the efficient business management in the operational strategy or its policy.

A Library is the fundamental character of culture in a country and it is also a barometer of culture in its community. Every cultural reality, however, can hardly come to fruition in a short time and so, it will be effected through a long time and tradition. This study aims at catching up how the above-mentioned public libraries have an influence on culture of its community people. For this purpose, the actual conditions of the public libraries have been investigated and analyzed and as a result of it, the problems have been reilluminated from the nation-wide point of view. And in the new changes, developing improvement measures have been tried to find. How to study was on the basis of the actual materials of the on the-spot survey, the interviews with the working officials and the response by way of questionnaire. Summing up the investigated and analyzed contents are as followings. In the above mentioned province, therefore, number of the public libraries are very limited compared with number of the people. And so, it is very essential to increase the public libraries in the province. In terms of the actual conditions, the public libraries lags far behind the other provinces in Korea from this library field. The present chronic conditions are the budgetary deficit, the collections insufficient to the legal minimal standards, the lack of professional librarians ignorance of the people and library managements by unprofessionals, etc.. This hinders the progress of the public libraries and to seculate them from the people. The improvements and the solutions to the above-mentioned problems are as follows. 1. To recruit the personnel sufficient to the legal standards and to reorganize the offices and to turn upward the highest class of librarian's position above the 4th class. 2. To secure collections sufficient to the legal standards and to strang then the extension services. 3. To organize the council composed of the chief librarians of the public libraries including the working chiefs in the province and to develop the works-in-hand of the libraries from the level of decision-making. 4. To organize the librarian training group and to study the working problems and to seek the qualified improvement of librarians. 5. The management of the public libraries in the province are, at present, der the Ministry of Education and the local government takes the financial power. So both should be shortly unified. 6. To do regularly the course of how to use library materials for the community people and to seek the inducement measures for the people through the various cultural events. 7. The public libraries organize the mutual cooperation networks and to seek the system automatized plans of free use of library materials and every library works. 8. To enlarge book mobile system actively and to infiltrate into the daily living of people deeply. Finally, what the present writer would like to speak to the chief librarians of the public libraries the human aspects of librarians should not be ignored no mater how excellent a library organization may be. In addition to this, the present writter is sure that the far-reached future of our library organization will depend on the librarians.

Objectives : We conducted an epidemiologic survey to evaluate the effect of the aircraft noise exposure on the health of the residents near the military airbases in Pyeongtaek City. Methods : The evaluation of environmental noise level, questionnaire survey, and health examination were performed for 917 residents. The study population consisted of four groups: subjects who lived in the village close to the fighter airbase (high exposure), subjects who lived along the course of fighters (intermediate exposure), and subjects near a helicopter airbase, and the control group. Results : The prevalence of the aircraft noise related accident and irritable bowel syndrome in the exposure groups were higher than that of the control group. The risks of noise induced hearing loss, hypertension and diabetes mellitus were higher in the exposed groups than in the control group. The prevalence of anxiety disorder and primary insomnia were higher in the exposed groups than in the control group. Prevalence odd ratios of the risk for primary insomnia after adjusting age, sex, agricultural noise, and occupation were 4.03 [95% confidence interval (95% Cl) 1.56-10.47] for the subject near the helicopter airbase, 1.23 (95% Cl 0.40-3.76) for those intermediately exposed to fighter noise, and 4.99 (95% Cl 2.14-11.64) for those highly exposed to fighter noise. Conclusions : The results of the present study suggest that the aircraft noise may have adverse effects on hearing function, cardiovascular health and mental health. Therefore, it seems to be needed to take proper measures including the control of the aircraft noise and the management of the exposed people's health.

Various accidents and injuries are currently occurring in Korea at increasingly high rates. Good quality emergency care service is urgently needed to cope with these various forms of accidents and injuries. In order to develop a sound emergency care system, there need to be a plan to educate and train professionals specifically in emergency care. One solution for the on going problem would be to educate and train emergency clinical nurse specialists. This study on a strategy for curriculum development for emergency clinical nurse specialist was based on the following five content areas, developed from literature related to the curriculum of emergency nursing and emergency care situation : 1. Nurses working in the emergency rooms of three university hospitals were analyzed for six days to identify categories of nursing activities. 2. Two hundreds and eleven nurses working in the emergency rooms of 12 university hospitals were surveyed to identify needs for educational content that should be included in a curriculum for the clinical nurse specialist. 3. Examination of the environment in which emergency management was provided. 4. Identification of characteristics of patients in the emergency room. 5. The role of emergency clinical nurse specialist was identified through literature, recent data, and research materials. The following curriculum was formulated using the above mentioned process. 1. The philosophy of education for emergency clinical nurse specialist was established through a realistic philosophical framework. In this frame, client, environment, health, nursing, and learning have been defined. 2. The purpose of education is framed on individual development, social structure, nursing process and responsibility along with the role and function of the emergency clinical nurse specialist. 3. The central theme was based on human, environment, health and nursing. 4. The elements of structure in the curriculum content were divided to include two major threads, I, e., vertical and horizontal : The vertical thread to consist of the client, life cycle, education, research, leadership and consultation, and the horizontal thread to consist of level of nursing (prevention to rehabilitation), and health to illness based on the health care system developed by Betty Neuman system model. 5. Behavioral objectives for education were structured according to the emergency clinical nurse specialist role and function as a master degree prepared in various emergency settings. 6. The content of the curriculum consisted of three core courses(9 credits), five major courses(15 credits), six elective courses(12 credits) and six prerequisite courses (12 credits). Thus 48 credits are required. Recommendations : 1. To promote tile quality of the emergency care system, the number of emergency professionals, has to be expanded. Further the role and function of the emergency clinical nurse specialist needs to be specified in both the medical law and the Nursing Practice Act. 2. In order to upgrade the qualification of emergency clinical nurse specialists, the course should be given as part of the graduate Program. 3. Certification should be issued through the Korean Nurses Association.

As an essential means to the exploitation of new demands, the export of agri-food has the price-supporting effect on the domestic agri-food and its expansion can be a good way to increase farms' income. Of course, to enhance farms' income under the liberalization of the market, it is necessary to have countermeasures considering various factors. To this end, the study understood the experiences of farms doing exports and looked into ways to improve them by reviewing their motivations to export, difficulties, requirements, etc. In this context, the study conducted the purposive sampling among tomato export farmhouses in Jeongseon-gun in the export enforcement phase and executed the theme analysis. The research findings and suggestions are as follows. First, in order to enhance the level of commercialization of Jeongseon-gun tomatoes and reinforce the trade bargaining power, it is necessary to form the consensus on policy and make the scaling of the site based on the strong organization power. To this end, it requires the active role of agricultural cooperatives that take a big portion of distribution in the site and distribute its profits directly to farmhouses. Second, it is necessary to set clear target markets for Jeongseon-gun tomato export farms and set sales strategies for each target market. That is, in order to expand the export of Jeongseon-gun tomatoes, after clarifying local sales and export sales, export farmhouses should focus on quality management and secure the quantity for export. Third, to expand the export to Japan which already has the foundation for the export of Korean tomatoes, and to new export countries of China, Russia, etc., it is necessary to set the 'Two-Track Strategies for Export Market (particular item for focus and particular area for focus)' through the building of network of tomato export areas in Gangwon-do. In conclusion, to expand the export of Jeongseon-gun tomatoes, agricultural cooperatives and leaders together should build the strong organizational power with farmhouses and secure the quantities for export. And, according to the 'Two-Track Strategies for Export Market (particular item for focus and particular area for focus)', export infrastructure and export operational system should be built and to do so, the solidarity of tomato export farmhouses in Gangwon area should precede.
