This thesis focuses on the study of costume and ornaments of Shilla which had been severely affected by Uighur, and those of Uighur in Uighur self-governing district located in Shin Kang. East Turkestan, in Centrals Asia. This study aims to identifty the way of intergration of Uighur's costume and ornaments into Shilla, and orgins of Shill's costume and ornaments which had amix of internationl elelemnts thoursh cross exchanges, by comparing the differences between the two, and at the same time to clarify the pedigree of Korean costume and ornaments which are said to be udner a severe Chinese influence, by highlingting its uniqueness and originality . The result of the study demonstrates and originality of SHilla by melting foreign cultures into its own style in the process of accepting them. This means that the Shilla has recreated them in t도 form of simplification, and added naturalistic abstratness which is an element of Norther culture. The costume and ornaments are divided into coronets men's costuem, women's costume, and accessories 1. Coroncts A horse-riding man, and the costume type of 유고제 착유지체형 tell the Northern culture's influence on 백화수피기마인물채화담립 and patterns of a lotus flowr and arabesque show the 백화수피기마인물채색답립 has an influence of Buddhism with cluture of bordering countries of Western China , The origin of 뱍회수피제안형건(원정형, 방정형) lies in Northern cultures which can be found in ancient tombs of the Huns in noin-Ila , and stone caves of Jizil in Kochang. The wall paintings in Alexandropol, Murutuk and 돈황 No. 409 cave show that 초화형입식계금관 is under the influence of Northern culture, and Bezerkrick No, 25 cave and 회 번 in Kocho also show 수목녹각형입식관 is under the influence of Northern culture, with its origin in Novecherkaask. In this regard, the transformed coroncts of Shilla has shows a blended culture of Shilla with Nothern, Chinese, and Western cultures. 2. Men's Costume 반령포 derives from cultures of bordering countries of Western China centering around Uighur and Turkey. 연주문 in Uighur prince's costume and in Uighur paintings of Central Asia were reflected into the arts of Shilla in a direct way, and the motive of Uighur was deviatelly expressed at Shilla's arts in the form of simplicity , and naturalistic abstract paintings as in shown at 입수쌍조문 in tiles and brick. Along with this , 고착지체형 costume originates from Eurasia's Northern horseriding costumes as was shown in a golden man in B.C.4-5C which is now possessed by Kazakstan Republic Academy Archelogy Center Museum, and a golden figure from Skitai ancient caves, an the origin is carried away into wall paintings of Kizil No.14. cave in 8c and Astana's early period ancient tomb. No.6. 3. Women's Costume The hair styles of Shilla people are either 변발 or up -style with a lot of hair around it whose origin can be seen in Astana No.216 and No.187 caves of Kochang and Uighur's wall paintings of royal princess's hair style. Astana's middle period No. 206 and No.230 tombs reveal the its origin of 고착장군 while Astana early period No. 6 tomb shows that of 광유풍만형. 4. Accessories The earrings with small golden beads is seen at earring of figure holding a sword in wall painting of figure holding a sword in wall painting of Kizil in about 5 C. and those of a offering people in Sorchuk wall paintings. The earrings with small golden beads originates from a golden pendant of Shivargan, Afganistan, and golden pendants and other golden and metal accessories from Chrioba ancient tombs in Skiti Critia peninsula. Shilla's costume derives from the costume style of horse-ridding man, which proves the fact that Shilla people are horse-ridding peoplewith excellent horse-ridding techniques, and traditions. The people of Shilla are from horse-ridding people of local mounted momads in Northern part of Siberia steppe and this origin of Northern culture had been carried into Uighur in East Turkestan. At the same time , Shilla has a wealth and power since it was rich in gold and iron , thus producing lots of materials made of them. The results of this study emphasizes Shilla's identity and self-control by creating an independent an innovative heterogeneous culture since Shill's active exchanges with East Asia allowed it to accept the most civilized Uighur culture in East Turkestan among Altai languate which had frequent cross contacts with India and Europe.

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.

본 연구에서는 부처꽃 에탄올 추출물(ELM)에 대한 항암효능을 알아보기 위하여 인체백혈병 U937 세포의 증식에 미치는 영향과 이와 연관된 apoptosis 유발 여부와 함께 그에 따른 분자생물학적 기전에 대해서 조사하였다. 먼저 ELM 처리에 따른 증식 억제 정도를 조사한 결과, ELM 처리 농도 의존적으로 생존율 및 증식억제 현상이 나타났으며, 핵의 형태 변화, DNA 단편화 및 apoptosis 유발에 관하여 조사한 결과 역시 ELM 처리 농도 의존적으로 증가됨을 확인할 수 있었다. ELM 처리에 따른 U937 세포에서의 apoptosis 유발에 있어서 미토콘드리아 막의 기능 손상이 관여하는 지를 확인하기 위하여 MMP의 변화 정도를 확인한 결과, ELM 처리 농도 증가에 따라 MMP의 소실이 증가하는 것을 관찰할 수 있었다. 이러한 MMP의 소실에 가 관여하는 지를 확인하기 위하여 사멸수용체(DR4, 5, Fas) 및 사멸수용체에 결합하는 리간드(FasL, TRAIL)의 발현 변화를 확인한 결과, DR4 및 DR5의 발현이 증가하는 것으로 관찰되었다. 또한 내인적 경로에 관여하는 Bcl-2 family 유전자들의 발현변화를 확인한 결과, Bcl-2 발현 감소 및 Bax의 발현 증가의 변화를 보였으며, Bid 단백질의 발현감소가 나타났으므로 상대적으로 tBid의 생성이 증가되었음을 추측할 수 있었다. 한편apoptosis 유발에 직접적으로 관여하는 것으로 알려진 caspase-3, -8 및 -9의 발현에 미치는 ELM의 영향에 대해서 조사하였다. 결과에서 알 수 있듯이 ELM은 death receptor에 의하여 활성화 되는 것으로 알려진 caspase-8 및 세포질로 방출된 cytochrome c에 의하여 활성화 되는 것으로 알려진 caspase-9의 활성화를 유발하였으며, caspase cascade에 의하여 apoptosis에 직접적으로 관여하는 caspase-3의 발현도 증가시키는 것으로 나타났다. 또한 활성화된 caspase-3에 의하여 분해가 일어나는 기질 단백질인 PARP의 경우 ELM 처리에 의하여 모두 단편화가 유발되는 것으로 나타났다. 이상의 결과를 종합해 보면 인체 백혈병 U937 세포에 ELM을 처리하였을 경우에 유발되는 apoptosis는 외인적 경로인 DR4 및 DR5의 발현 증가를 통한 caspase-8의 활성화와 이로 인한 Bid 단백질의 단편화와 함께 내인적 경로의 미토콘드리아 기능 손실에 의하여 caspase-9 및 -3의 활성화 유발과 기질단백질들의 분해가 중요한 역할을 하는 것으로 생각되며, IAP family의 발현 감소로 인하여 caspase의 활성이 억제되지 못하는 것도 apoptosis 유도에 어느 정도 관여했을 것으로 생각된다. 따라서 ELM 처리에 의하여 유발되는 apoptosis는 외인적 경로 및 내인적 경로를 모두 경유하는 multiple apoptotic pathway에 의하여 조절되며, 이때 caspases가 중요한 역할을 한다는 것을 알 수 있었다.

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.

The present study conducted a survey on the correlation between job satisfaction of dental hygienists and their workplace satisfaction and quality of life. A total of 249 surveys eligible among all the collected surveys were used in the analysis. The survey consisted of 61 items; 35 items were about self-evaluations of their satisfaction with their tasks, occupation, and workplace, as well as the degree of self-affirmation and their family-related satisfaction; the rests were 26 WHOQOL-BREF items investigating the quality of life. Collected data were processed using the SPSS Ver. 10.0 calculating the reliability with the frequency, percentage, and Cronbach's ${\alpha}$. Besides, one-way ANOVA and linear regression analysis examined the correlation between the variables. The conclusion is as follows: 1. By Age: Job satisfaction and family-related satisfaction were highest in the subjects aged 30 or older($3.5377{\pm}0.6891$ at pF0.05 and $4.1789{\pm}0.5431$ at pF0.05, respectively), though the differences were not statistically significant). Workplace satisfaction and self-affirmation were also highest in those aged 30 or order($3.5753{\pm}0.4210$ at pE0.05 and $3.9695{\pm}0.4616$ at pE0.05, respectively). The differences were statistically significant. Quality of life was also highest in those aged 30 or older($3.4095{\pm}0.3529$, pF0.05). 2. By Types of Dental Institutions: Job satisfaction and workplace satisfaction were highest in the subjects who worked at the dental department in a general hospital($3.7431{\pm}0.5940$ at pF0.05 and $3.6615{\pm}0.4602$ at pF0.05. respectively), though without statistical significance. Self-affirmation was highest in those working in university hospitals($3.773{\pm}0.7151$, pF0.05), while family-related satisfaction was highest, though without statistical significance, in those working at the dental department in general hospitals($4.2500{\pm}0.5528$, pF0.05), who also showed highest quality of life with statistical significance($3.4046{\pm}0.4155$, pE0.05). 3. By Years at Work: The subjects who had worked as a dental hygienist for 12 years or more showed highest satisfaction or scores in all the variables investigated: job satisfaction($3.9326{\pm}0.6673$, pE0.05): workplace satisfaction($3.8316{\pm}0.4342$, pE0.05): self-affirmation($4.2000{\pm}0.4551$, pE0.05); family-related satisfaction($4.3778{\pm}0.4692$, pF0.5): and quality of life($3.5235{\pm}0.4323$, pF0.05). All but quality of life showed a difference with statistical significance. 4.
