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.

방사선은 의료, 연구, 산업 등 다양한 분야에서 활용되고 있어 방사선 이용기관 및 방사선작업종사자의 수가 증가하고 있으며, 방사선 관련 피폭 사고도 발생함에 따라 방사선방호 및 안전에 대한 관심이 증가하고 있다. 이에 원자력안전법에서는 방사선원을 이용하는 장소에 대해서는 선량한도를 초과하지 않도록 하기 위해 차폐물을 설치하도록 규정하고 있다. 특히, 고정 설치된 차폐시설이 없는 곳에서 방사선투과검사 작업 수행 시, 일정한 선량율을 기준으로 작업장 출입 및 일반인 접근 여부를 감시하고 있다. 하지만, 고정 설치된 차폐시설 없는 곳에서의 방사선투과검사 작업 허가 신청 시, 방사선관리구역 및 (일반인) 감시구역거리 및 해당 거리에서의 피폭선량 계산에 고려해야 할 인자들은 법적으로 규정되어 있지 않다. 이에 본 연구에서는 방사선방호용 도구(납 담요, Collimator)의 특성(규격, 두께 등), 사용 선원 등을 입력 시, 자동으로 방사선관리구역 및 (일반인) 감시구역 거리와 비용을 산정해 주는 Excel model을 개발하였다. 이후 특정 가정을 바탕으로 방사선방호용 도구 두께에 따른 피폭선량 및 거리 변화율을 분석한 결과, 방사선방어용 도구의 두께가 증가함에 따라 방사선관리구역의 거리는 감소하였으나, 납 담요 두께가 25 mm, Collimator의 두께가 21.5 mm 이상부터는 거리의 변화율이 낮았다. 따라서, 해당 두께 이상의 방사선방어용 도구를 사용하고도 방사선관리구역 및 (일반인) 감시구역에서의 피폭선량이 높은 경우, 방사선방어용 도구 이외의 요소를 변화시켜 피폭선량을 낮추어야 할 것으로 예상된다. 또한, 본 연구에서는 1) 피폭선량 계산 시, 산란성 및 Build up 등을 고려하지 않은 점, 2) 납 담요 및 Collimator의 실제 모양이 아닌 직육면체와 중심이 빈 원기둥 모양으로 가정 등으로 인해 실제 피폭선량과 차이가 있다는 한계점이 있었다. 따라서, 향후 앞선 한계점들을 고려하면서 실제 작업환경에 대한 자료를 활용하여 연구를 수행한다면, 실제 작업환경을 바탕으로 방사선관리구역 거리 및 피폭선량 등에 대한 Database 구축이 가능할 것으로 예상된다.

Our country has been consuming a huge amount of energy in the course of industrialization and its demand is expected to increase enormously in the future. However, the deposits of energy resources are so limited that the settlement of energy problem comes up the essential subject. To solve the energy problem, it is requested that new resources to gain energy stably should be developed and also energy should be economized and used effectively. The effective use of energy and an the wisdom of economy in energy are requested to everybody and these things should be habitualized from very young age through education. Nevertheless, almost every school in our country hasn’t been concerned about energy education. Even though they have a concern, they are very short of the energy education materials and the quality of the materials is not so good. Therefore it is very meaningful to the settlement of energy problem of the country to make the students who will lead our country to make the students who will lead our country in the future realize the seriousness of energy problem and to provide them the necessary knowledge and methods to solve this problem so that they practice those things in everyday life. Having these necessities, this research, supported by The Korea Energy Management Corporation(KEMCO), was performed for 8 months from April 17, 1994 to December 17, 1994. Many peoples participated in this study such as 30 staffs of researchers and authors, 5 staffs of photographers and illustrators, and 3 VCR program producers developing an energy education material set for middle school students that includes a printed material for student, a diskette for computer simulation, a teacher's guidebook, VCR material and its guidebook. The following main development direction was established : First, the material for student should be consisted of units that let students know the seriousness of energy problem. Second, the focus should be put on the necessary method and practice to economize energy actually in real life based on the basic knowledge learned in elementary school. Third, material for student should be consisted of modules to be student activity-oriented teaching-learning rather than lecture-oriented one. The activity, to maximize student's interests, should be presented in various forms such as experiments, investigation, play, data interpretation, computer simulation, visits, expression and appreciation, etc. To develop the energy education materials for middle school students, a research plan was made first. After literature review about domestic and foreign energy education materials, several research trips home and abroad, and discussion meetings, the basic theory of energy education such as the principle, objective, contents, teaching-learning method, and evaluation method was established. Material for student was developed through the following procedures : The activities in the existing energy education materials were analysed and were divided into four categories related to energy using places of home, school, community, and country, and which were again divided into three categories related to time of past, present, and future, Considering these division, nine modules which are structure units of material for student were chosen, Each module comprises 2-4 activities. Totally 31 activities were designed in this way. The syllabi were made out for each activity and writing was asked for to experts related to each activity after several discussions and revision. To complement the draft, another several discussions and revision were also made on it and then pictures and illustrations were asked for. All these procedures complete the material for student, titled ; Energy Inquiry of Middle School Students', which totals 129 pages and is all in color. As the manuscript of material for student was fixed, writing for teacher's guidebook was asked for to the same writers. The draft of teacher's guidebook was also complemented through the several concentrated works and discussions. Teacher's guidebook focused on the teaching-learning principle and methods of energy education and on the concrete instruction cases for effective instruction of material for student. It is organized with two parts : the one is 'general outline' which introduces theoretical contents and the other is 'details' which are practically helpful to teaching-learning. It is totally 131 pages including both 'general outline' and 'details'. The VCR material and its guidebook consist of contents that cultivate the good attitude trying to economize energy and raise student's interests with a purpose of strong motivation to recognize the necessity of economy and practice it. After establishing development direction of VCR material through discussion meetings and research trips, its script was made by relevant experts. Then the script was also reviewed two times. The drafted VCR material made by a video material developing expert was examined and modified by previews twice. After completion of VCR material, the VCR guidebook was made. All these procedures led to the development of VCR material which runs 20 minutes in VHS type. The VCR guidebook shows a production purpose of the program, structure of contents, evaluation methods, and contents of the program in detail to give help to instructors when they use this VCR material, When these energy education materials are used, it is desirable that the VCR material should be presented first to induce student's motive, and then material for student is introduced Since the material for student is composed of activity-oriented modules and each module is independent one another in general, and each activity is, too. the necessary module or activity can be chosen and utilized in any order according to school or class conditions. This energy education materials will contribute to the development of student's ability to solve energy problem in everyday life and teacher's ability to teach the fundamental knowledge and method in solving energy problem.

본 연구는 수삽을 이용한 'Fuji' 사과나무의 발아 특성 관찰을 통해 자연상태에서의 내재휴면 개시 및 타파 시점을 찾고, 이에 필요한 저온요구도를 파악하고자 하였다. 또한, 동시에 휴면과 발아와의 관계를 좀 더 명확히 하고자 내부적인 눈의 발달 양상을 관찰하여 휴면과 저온 및 눈 발달간의 상호연관성을 파악하여 기후변화에 따른 변화들을 예상하고 대처하는데 필요한 기초 자료를 제공하고자 수행하였다. 'Fuji' 사과나무의 내재휴면 기간은 발아 소요 일수 및 발아율 조사를 통해 만개 후 165일부터 255일 사이 즉, 10월말부터 이듬해 1월 초까지 약 70일 정도 지속됨을 알 수 있었으며, 최초 발아까지 20일 이내, 최종 발아율 60% 이상을 기준으로 외재휴면에서 내재휴면으로, 다시 내재휴면에서 환경휴면으로 전환되는 시점을 찾을 수 있었다. 이렇게 도출된 내재휴면기 동안 요구되는 저온을 산출한 결과, 내재 휴면타파기인 만개 후 255일까지 축적된 저온은 CH 모델의 경우 666h, Utah 모델은 517CU으로 조사되었다. 휴면기 및 휴면타파기 동안 눈의 내부적인 변화를 관찰한 결과, 7월 중순경부터 꽃눈분화가 시작되었으며, 9월에는 중심화의 화원기의 구분이 가능하였다. 이후 꽃눈의 발달은 휴면 기간 동안에도 느리지만 지속적으로 진행되어 이듬해 2월에는 각 기관들의 발육 단계가 좀 더 진전되어 있음이 관찰되었다. 또한 'Fuji' 사과의 눈은 휴면 기간 동안 대부분 건전하게 생존해 있었지만 일부에서 화원기의 괴사현상이 발견되었고, 이는 저온에 의한 직접적인 영향이기보다는 얼음결정 형성으로 인해 일부 조직의 세포가 피해를 입고, 이로부터 괴사가 진행되고 있음을 확인하였다. 이러한 꽃눈은 과대지의 액아와 단과지의 정아에서 모두 형성되었으나, 전체 꽃눈 중 약 65%의 비율로 단과지의 정아에서 더 많은 꽃눈이 분화되고 있었으며, 이는 눈의 크기 및 눈이 위치한 가지의 직경과 직접적인 연관이 있었다.

Despite prologed business stagnation of both international and domestic economy, hotel business as well as tourist industry has continuously been keeping growing, owing to increase of surplus income and world flowing population. During recent 4 years, growth rate of yearly mean in domestic hotels reached 9.9% and especially that of the superior class hotels 15.2%. In the composition of domestic tourist hotel's revenue, the earnings of guest rooms form 37.4%, on the other hand those of food & beverage 39.9%. This result is that our hotel business is concentrated on its interest in FOOD & BEVERAGE of which productivity per unit dimension can be increased to an unlimited extent and extent and superior class hotels strengthened in F&B are increasing in comparison with European or American hotels which are focused on guest rooms in their management. For value added rate of F&B is low as compared with increase of their earnings, they are interested in the management techniques which focus on rising the rate. As for the cost of Food & Beverage, personnel expenditure forms 36.5% and the direct materials 31.5%. Therefore how to manage personnel and materials costs which compose as much as 68% of total revenue will greatly affect net profit. We can say that an effective management technique in cost of Food & Beverage is one of the most important know-hows in hotel management. Especially management know-how for the Kitchen Department where the most of foods come out makes a great effects on various expenses, productivity and it is the achievement from hotel management. For the most of the hotel's top managers, they don't seriously take the fact that KITCHEN SYSTEM affects greatly total expenditure. This study starts from the point of recognizing the question of fundamental cause affecting tow largest cost elements incurred in Food & Beverage and trying to present an effective kitchen system. To settle the questions raised, I compared and analyzed productivity and cost of food & beverage and unit kitchen centered around superior class hotels in Seoul, which vary in Kitchen Systems. In order to attain the aforementioned study effectively purpose of this study, I compared Room-Service and Coffee-Shop Menu, flow of basic food in the kitchen, extent and result of division of labor and integration in the kitchen, scale of outlet kitchen, productivity, the turnover rate of food in store, food cost rate one another which all vary in Kitchen Systems. All these elements are compared and analyzed each other being divided into two main groups such as①. Main Production kitchen and Banquet Kitchen, and ②. coffee-shop kitchen and Room-service Kitchen. Therefore this study is to point out the problems in managing kitchens of superior class hotels which are different in systems. An effort was made to find out the better Kitchen System for superior deluxe hotels. I emphasize the followings on the proper scale of division of labor and integration of unit kitchen and a disposition plan for outlet kitchens of restaurant. First, KITCHEN SYSTEM as a sub-system of Hotel Management System is composed of sub-systems of outlet unit kitchen. Basic food materials are cooked and served for the guests while support kitchen and out restaurant kitchen interact organically each other. So Kitchen should be considered as a system composed of integrated sub-systems. Second, support and banquet kitchens should be integrated to be managed. And these unit kitchens have to be designed to be placed in the back of banquet rooms area. Third, coffee-shop kitchen and room-service kitchen should be integrated to be managed. Fourth, several unit business kitchens should be place on the same floor. Fifth, main production kitchens ought to be located near the loading duck, food store and large refrigerator. Sixth, considering the limits of supervision, duties should be adjusted as 12-20 cooks in two shifts a day for a sub-kitchen, and 18-30 cooks in three shifts a day so that labor division can be made. Last, I would like to two points for direction and task of future study. Firstly, I compare the effective income and increasing costs each other, which are incurred by increasing the use rate of the second processing materials for foods perched outside and through the results. I can find out the better points of the processing production and circulation system, and then I study this effects made on hotel kitchen system. Secondly, I can point out that more efficient kitchen system shall be established through comparing and analyzing the matter of amount of indirect costs and flow of food in different kitchen systems.

The purpose of this study was to examine the relationship between the Dentocult SM and LB scores of students and their DMF rate. The subjects in this study were 134 special school students in south Gyeong-sang province. After they were tested to find out their, they received tooth brushing education and preventive treatment. The test, education and treatment were all conducted from March 17 to April 9, 2008. Their oral state was checked and recorded by using a mirror and explorer, and then the data on oral state were analyzed to their DMFT, DT, FT and MT rates. All the collected data were analyzed with SPSS 15.0 for Windows program, and independent-samples t-test, one-way ANOVA and crosstabs analysis were implemented to see what differences their disability type, gender, Dentocult-SM scores and Dentocult-LB scores made. The findings of the study were as follows: 1. As for connections between disability type and DMFT rate, the students with mental retardation were similar to the other students in that regard. The mentally retarded students had higher DT and FT rates than the other students, and the MT rate of the latter was higher than that of the former. 2. Concerning the relationship of gender to DMFT and DT rates, the girls had larger DMFT and DT rates than the boys, and the FT and MT rates of the boys were higher than those of the girls. 3. As to links between Dentocult SM scores on the tongue and DMFT, the students whose bacteria was mildly activated had the highest DMFT rate, and the students who had a severely activated bacteria had the highest DT and FT rates. Those who had a moderately activated bacteria had the highest MT rate. 4.Regarding the connection of Dentocult SM scores on maxillyright molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates.
