문화재의 범죄예방환경에서 중요한 요인 중의 하나인 감시강화는 현장평가와 진단에 어려움이 있다. 이로 인해 감시강화는 문화재 형상, 지형, 수목 등을 디지털로 모델링하여 컴퓨팅 기술로 평가하는 접근이 이루어진다. 본 연구는 입체형상으로 감시강화를 정량적으로 평가할 수 있는 3차원 시각노출도 지표(3DVE, 3D Visual Exposure)를 이용하여 문화재 범죄예방환경의 평가기법을 개발하는 것을 목적으로 하였다. 연구를 위해 평가요인을 자연적 감시, 조직적 감시, 기계적 감시 그리고 통합적 감시로 세분하여 분석을 수행하였다. 분석을 위해서 건물, 지형, 담장, 수목 등의 형상을 입체적으로 모델링하였으며, Unity 3D를 이용하여 분석 프로그램을 제작하였다. 사람의 작업영역을 고려하여 머리위치와 허리위치로 구분하여 감시지점을 분석할 수 있도록 하였다. 분석 프로그램으로 3DVE의 활용 가능성을 검증하기 위해 논산에 소재한 돈암서원(사적 제383호)을 디지털로 모델링하여 범죄예방환경을 평가하였다. 연구결과 돈암서원의 자연적 감시, 기계적 감시, 조직적 감시에서 취약지점, 사각지대, 순찰동선의 문제점 등의 발견이 가능하였다. 3DVE 분석결과를 3차원 도면으로 제작함으로써 위치와 대상을 명확하게 표현할 수 있었다. 주간 감시성은 자연적 감시, 기계적 감시, 조직적 감시 순으로 높지만, 야간 감시성은 조직적 감시, 기계적 감시, 자연적 감시 순으로 높게 나타났다. 작업영역의 위치가 낮을수록 차폐되기 용이하므로, 허리위치에 대한 평가가 이루어질 필요가 있는 것으로 파악되었다. CCTV의 제원과 설치 위치, 높이에 따른 감시범위를 산출하게 됨으로써 사각지대의 발견과 표시가 가능하게 되었다. 기계적 감시의 보완효과가 있는 것으로 밝혀진 조직적 감시는 범죄취약 시간대에 분석이 요구된다. 또한 보안등, CCTV, 순찰동선 등의 설정을 검토하는데 통합적 감시도 분석이 효과적일 수 있다. 본 연구는 실제를 시뮬레이션으로 제작하여 범죄예방환경을 진단할 수 있는 성과를 거두었다. 본 연구를 기반으로 범죄예방환경설계의 대안을 평가하고 비교할 수 있는 연구가 수행되어야 한다.

Just before the Korean War, the total number of the North Korean troops was 198,380, while that of the ROK(Republic of Korea) army troops 105,752. That is, the total number of the ROK army troops at that time was 53.3% of the total number of the North Korean army. As of December 2008, the total number of the North Korean troops is estimated to be 1,190,000, while that of the ROK troops is 655,000, so the ROK army maintains 55.04% of the total number of the North Korean troops. If the ROK army continues to reduce its troops according to [Military Reform Plan 2020], the total number of its troops will be 517,000 m 2020. If North Korea maintains the current status(l,190,000 troops), the number of the ROK troops will be 43.4% of the North Korean army. In terms of units, just before the Korean War, the number of the ROK army divisions and regiments was 80% and 44.8% of North Korean army. As of December 2008, North Korea maintains 86 divisions and 69 regiments. Compared to the North Korean army, the ROK army maintains 46 Divisions (53.4% of North Korean army) and 15 regiments (21.3% of North Korean army). If the ROK army continue to reduce the military units according to [Military Reform Plan 2020], the number of ROK army divisions will be 28(13 Active Division, 4 Mobilization Divisions and 11 Local Reserve Divisions), while that of the North Korean army will be 86 in 2020. In that case, the number of divisions of the ROK army will be 32.5% of North Korean army. During the Korean war, North Korea suddenly invaded the Republic of Korea and occupied its capital 3 days after the war began. At that time, the ROK army maintained 80% of army divisions, compared to the North Korean army. The lesson to be learned from this is that, if the ROK army is forced to disperse its divisions because of the simultaneous invasion of North Korea and attack of guerrillas in home front areas, the Republic of Korea can be in a serious military danger, even though it maintains 80% of military divisions of North Korea. If the ROK army promotes the plans in [Military Reform Plan 2020], the number of military units of the ROK army will be 32.5% of that of the North Korean army. This ratio is 2.4 times lower than that of the time when the Korean war began, and in this case, 90% of total military power should be placed in the DMZ area. If 90% of military power is placed in the DMZ area, few troops will be left for the defense of home front. In addition, if the ROK army continues to reduce the troops, it can allow North Korea to have asymmetrical superiority in military force and it will eventually exert negative influence on the stability and peace of the Korean peninsular. On the other hand, it should be reminded that, during the Korean War, the Republic of Korea was attacked by North Korea, though it kept 53.3% of troops, compared to North Korea. It should also be reminded that, as of 2008, the ROK army is defending its territory with the troops 55.04% of North Korea. Moreover, the national defense is assisted by 25,120 troops of the US Forces in Korea. In case the total number of the ROK troops falls below 43.4% of the North Korean army, it may cause social unrest about the national security and may lead North Korea's misjudgement. Besides, according to Lanchester strategy, the party with weaker military power (60% compared to the party with stronger military power) has the 4.1% of winning possibility. Therefore, if we consider the fact that the total number of the ROK army troops is 55.04% of that of the North Korean army, the winning possibility of the ROK army is not higher than 4.1%. If the total number of ROK troops is reduced to 43.4% of that of North Korea, the winning possibility will be lower and the military operations will be in critically difficult situation. [Military Reform Plan 2020] rums at the reduction of troops and units of the ground forces under the policy of 'select few'. However, the problem is that the financial support to achieve this goal is not secured. Therefore, the promotion of [Military Reform Plan 2020] may cause the weakening of military defence power in 2020. Some advanced countries such as Japan, UK, Germany, and France have promoted the policy of 'select few'. However, what is to be noted is that the national security situation of those countries is much different from that of Korea. With the collapse of the Soviet Unions and European communist countries, the military threat of those European advanced countries has almost disappeared. In addition, the threats those advanced countries are facing are not wars in national level, but terrorism in international level. To cope with the threats like terrorism, large scaled army trops would not be necessary. So those advanced European countries can promote the policy of 'select few'. In line with this, those European countries put their focuses on the development of military sections that deal with non-military operations and protection from unspecified enemies. That is, those countries are promoting the policy of 'select few', because they found that the policy is suitable for their national security environment. Moreover, since they are pursuing common interest under the European Union(EU) and they can form an allied force under NATO, it is natural that they are pursing the 'select few' policy. At present, NATO maintains the larger number of troops(2,446,000) than Russia(l,027,000) to prepare for the potential threat of Russia. The situation of japan is also much different from that of Korea. As a country composed of islands, its prime military focus is put on the maritime defense. Accordingly, the development of ground force is given secondary focus. The japanese government promotes the policy to develop technology-concentrated small size navy and air-forces, instead of maintaining large-scaled ground force. In addition, because of the 'Peace Constitution' that was enacted just after the end of World War II, japan cannot maintain troops more than 240,000. With the limited number of troops (240,000), japan has no choice but to promote the policy of 'select few'. However, the situation of Korea is much different from the situations of those countries. The Republic of Korea is facing the threat of the North Korean Army that aims at keeping a large-scale military force. In addition, the countries surrounding Korea are also super powers containing strong military forces. Therefore, to cope with the actual threat of present and unspecified threat of future, the importance of maintaining a carefully calculated large-scale military force cannot be denied. Furthermore, when considering the fact that Korea is in a peninsular, the Republic of Korea must take it into consideration the tradition of continental countries' to maintain large-scale military powers. Since the Korean War, the ROK army has developed the technology-force combined military system, maintaining proper number of troops and units and pursuing 'select few' policy at the same time. This has been promoted with the consideration of military situation in the Koran peninsular and the cooperation of ROK-US combined forces. This kind of unique military system that cannot be found in other countries can be said to be an insightful one for the preparation for the actual threat of North Korea and the conflicts between continental countries and maritime countries. In addition, this kind of technology-force combined military system has enabled us to keep peace in Korea. Therefore, it would be desirable to maintain this technology-force combined military system until the reunification of the Korean peninsular. Furthermore, it is to be pointed out that blindly following the 'select few' policy of advanced countries is not a good option, because it is ignoring the military strategic situation of the Korean peninsular. If the Republic of Korea pursues the reduction of troops and units radically without consideration of the threat of North Korea and surrounding countries, it could be a significant strategic mistake. In addition, the ROK army should keep an eye on the fact the European advanced countries and Japan that are not facing direct military threats are spending more defense expenditures than Korea. If the ROK army reduces military power without proper alternatives, it would exert a negative effect on the stable economic development of Korea and peaceful reunification of the Korean peninsular. Therefore, the desirable option would be to focus on the development of quality of forces, maintaining proper size and number of troops and units under the technology-force combined military system. The tableau above shows that the advanced countries like the UK, Germany, Italy, and Austria spend more defense expenditure per person than the Republic of Korea, although they do not face actual military threats, and that they keep achieving better economic progress than the countries that spend less defense expenditure. Therefore, it would be necessary to adopt the merits of the defense systems of those advanced countries. As we have examined, it would be desirable to maintain the current size and number of troops and units, to promote 'select few' policy with increased defense expenditure, and to strengthen the technology-force combined military system. On the basis of firm national security, the Republic of Korea can develop efficient policies for reunification and prosperity, and jump into the status of advanced countries. Therefore, the plans to reduce troops and units in [Military Reform Plan 2020] should be reexamined. If it is difficult for the ROK army to maintain its size of 655,000 troops because of low birth rate, the plans to establish the prompt mobilization force or to adopt drafting system should be considered for the maintenance of proper number of troops and units. From now on, the Republic of Korean government should develop plans to keep peace as well as to prepare unexpected changes in the Korean peninsular. For the achievement of these missions, some options can be considered. The first one is to maintain the same size of military troops and units as North Korea. The second one is to maintain the same level of military power as North Korea in terms of military force index. The third one is to maintain the same level of military power as North Korea, with the combination of the prompt mobilization force and the troops in active service under the system of technology-force combined military system. At present, it would be not possible for the ROK army to maintain such a large-size military force as North Korea (1,190,000 troops and 86 units). So it would be rational to maintain almost the same level of military force as North Korea with the combination of the troops on the active list and the prompt mobilization forces. In other words, with the combination of the troops in active service (60%) and the prompt mobilization force (40%), the ROK army should develop the strategies to harmonize technology and forces. The Korean government should also be prepared for the strategic flexibility of USFK, the possibility of American policy change about the location of foreign army, radical unexpected changes in North Korea, the emergence of potential threat, surrounding countries' demand for Korean force for the maintenance of regional stability, and demand for international cooperation against terrorism. For this, it is necessary to develop new approaches toward the proper number and size of troops and units. For instance, to prepare for radical unexpected political or military changes in North Korea, the Republic of Korea should have plans to protect a large number of refugees, to control arms and people, to maintain social security, and to keep orders in North Korea. From the experiences of other countries, it is estimated that 115,000 to 230,000 troops, plus ten thousands of police are required to stabilize the North Korean society, in the case radical unexpected military or political change happens in North Korea. In addition, if the Republic of Korea should perform the release of hostages, control of mass destruction weapons, and suppress the internal wars in North Korea, it should send 460,000 troops to North Korea. Moreover, if the Republic of Korea wants to stop the attack of North Korea and flow of refugees in DMZ area, at least 600,000 troops would be required. In sum, even if the ROK army maintains 600,000 troops, it may need additional 460,000 troops to prepare for unexpected radical changes in North Korea. For this, it is necessary to establish the prompt mobilization force whose size and number are almost the same as the troops in active service. In case the ROK army keeps 650,000 troops, the proper number of the prompt mobilization force would be 460,000 to 500,000.

2000년대 후반 이후 북중 접경지역에 입지한 한국 투자기업은 북한의 핵실험 및 미사일 도발 행위에 대한 국제 사회 및 우리나라 독자적 대북 제재 조치로 인해 위탁가공 거래 단절과 탈입지를 경험하고 있다. 그러나 2013년 북중 접경지역에 출경가공무역 제도의 도입은 중국 내수 시장 기반의 대북 위탁가공 생산의 활성화를 가져왔다. 그 결과, 그동안 대북 위탁가공 거래에서 우리나라가 차지했던 역할을 중국기업들이 대신하면서 북중 접경지역의 대북위탁가공 네트워크의 지리는 더욱 복잡하게 형성되었다. 따라서 본 논문은 북중 접경지역 랴오닝성 단둥시에 입지하고 있는 대북 위탁가공 업체들을 사례로 이들의 대북 위탁가공 생산 네트워크의 특성을 분석함으로써 접경지역이 갖는 예외적 성격을 분석하였다. 기본적으로 대북 위탁가공 생산 네트워크의 형성은 북한의 양질의 저임금 노동력 활용하기 위해서이다. 이와 같은 네트워크 형성을 가능하게 한 요인은 크게 두 가지 측면에서 바라볼 수 있다. 첫째, 북중간 경제교류 강화와 북한을 개발의 대상으로 바라본 지경학적 요인이다. 예를 들어, 출경가공무역의 도입은 제3국 수출보다는 중국 내수 시장을 기반으로 하는 접경지역 기업에게 대북 위탁가공무역을 허용함으로써 이들 기업이 제도적으로 북한의 풍부한 양질의 저임금 노동력에 접근 가능하게 하였다. 둘째, 지경학적 수단을 통한 북한 체제 안정을 위한 지정학적 요인이다. 대북 위탁가공 생산 네트워크의 활성화는 북한의 외화벌이를 보장하기 때문에 북한이 체제의 완충국으로서 역할을 지속 가능하게 한다. 이는 체제의 완충국으로서 북한의 경제 및 체제 안정을 적극적으로 관리하기 위한 중국의 지전략적 의도가 반영된 것이라 할 수 있다. 다시 말해, 대북 위탁가공 네트워크는 지경학과 지정학이라는 두 가지 대비되는 담론적 실천에 의해 영향을 받고, 더 나아가 북중 접경지역의 공간경제 특성을 우연적이면서 다채로운 모습으로 그려낸다. 결론적으로 북중 접경지역은 각종 변경무역제도와 출경가공무역제도와 같이 자본과 노동의 이동성을 높여주는 예외적인 법률과 제도가 작동하는 공간이며, 대북 위탁가공을 통해서 북한의 양질의 노동력을 매우 낮은 비용으로 활용함으로써 잉여가치가 창출되는 착취의 공간적 특성이 나타난다.

The major objective of this research is to identify those hospital characteristics that best explain cost variation among hospitals and to formulate linear models that can predict hospital costs. Specific emphasis is placed on hospital output, that is, the identification of diagnosis related patient groups (DRGs) which are medically meaningful and demonstrate similar patterns of hospital resource consumption. A casemix index is developed based on the DRGs identified. Considering the common problems encountered in previous hospital cost research, the following study requirements are estab-lished for fulfilling the objectives of this research: 1. Selection of hospitals that exercise similar medical and fiscal practices. 2. Identification of an appropriate data collection mechanism in which demographic and medical characteristics of individual patients as well as accurate and comparable cost information can be derived. 3. Development of a patient classification system in which all the patients treated in hospitals are able to be split into mutually exclusive categories with consistent and stable patterns of resource consumption. 4. Development of a cost finding mechanism through which patient groups' costs can be made comparable across hospitals. A data set of Medicare patients prepared by the Social Security Administration was selected for the study analysis. The data set contained 27,229 record abstracts of Medicare patients discharged from all but one short-term general hospital in Connecticut during the period from January 1, 1971, to December 31, 1972. Each record abstract contained demographic and diagnostic information, as well as charges for specific medical services received. The 'AUT-OGRP System' was used to generate 198 DRGs in which the entire range of Medicare patients were split into mutually exclusive categories, each of which shows a consistent and stable pattern of resource consumption. The 'Departmental Method' was used to generate cost information for the groups of Medicare patients that would be comparable across hospitals. To fulfill the study objectives, an extensive analysis was conducted in the following areas: 1. Analysis of DRGs: in which the level of resource use of each DRG was determined, the length of stay or death rate of each DRG in relation to resource use was characterized, and underlying patterns of the relationships among DRG costs were explained. 2. Exploration of resource use profiles of hospitals; in which the magnitude of differences in the resource uses or death rates incurred in the treatment of Medicare patients among the study hospitals was explored. 3. Casemix analysis; in which four types of casemix-related indices were generated, and the significance of these indices in the explanation of hospital costs was examined. 4. Formulation of linear models to predict hospital costs of Medicare patients; in which nine independent variables (i. e., casemix index, hospital size, complexity of service, teaching activity, location, casemix-adjusted death. rate index, occupancy rate, and casemix-adjusted length of stay index) were used for determining factors in hospital costs. Results from the study analysis indicated that: 1. The system of 198 DRGs for Medicare patient classification was demonstrated not only as a strong tool for determining the pattern of hospital resource utilization of Medicare patients, but also for categorizing patients by their severity of illness. 2. The wei틴fed mean total case cost (TOTC) of the study hospitals for Medicare patients during the study years was $11,27.02 with a standard deviation of $117.20. The hospital with the highest average TOTC ($1538.15) was 2.08 times more expensive than the hospital with the lowest average TOTC ($743.45). The weighted mean per diem total cost (DTOC) of the study hospitals for Medicare patients during the sutdy years was $107.98 with a standard deviation of $15.18. The hospital with the highest average DTOC ($147.23) was 1.87 times more expensive than the hospital with the lowest average DTOC ($78.49). 3. The linear models for each of the six types of hospital costs were formulated using the casemix index and the eight other hospital variables as the determinants. These models explained variance to the extent of 68.7 percent of total case cost (TOTC), 63.5 percent of room and board cost (RMC), 66.2 percent of total ancillary service cost (TANC), 66.3 percent of per diem total cost (DTOC), 56.9 percent of per diem room and board cost (DRMC), and 65.5 percent of per diem ancillary service cost (DTANC). The casemix index alone explained approximately one half of interhospital cost variation: 59.1 percent for TOTC and 44.3 percent for DTOC. Thsee results demonstrate that the casemix index is the most importand determinant of interhospital cost variation Future research and policy implications in regard to the results of this study is envisioned in the following three areas: 1. Utilization of casemix related indices in the Medicare data systems. 2. Refinement of data for hospital cost evaluation. 3. Development of a system for reimbursement and cost control in hospitals.

본 연구는 현재까지 수행된 독도 화산체 정상부 해역의 정밀수심 및 지구물리 조사 자료를 종합하고 분석하여 정상부 해역의 정밀해저지형 및 지구물리학적 특성을 연구하였다. 독도 연안역 동도와 서도 사이 연결 수로는 약 10 m 이내의 얕은 수심을 이루고 있다. 독도 화산체 정상부해역의 전체적인 수심은 동도와 서도의 육지부부터 수면 아래 약 30 m 까지는 불규칙하며 급한 경사면을 가지고, 그 후 수심 약 30 m부터 수심 약 80 m 까지는 경사가 점차 낮아지다가 수심 약 80 m 이하로 완만한 경사를 보이면서 외해역으로 깊어진다. 독도 육지부와 그 북동쪽 및 북서쪽으로 연장되는 암반들은 독도를 생성시킨 화구륜의 잔해로 판단되며 동도와 서도는 화구륜의 남쪽 한부분일 가능성이 큰 것으로 생각된다. 또한 정상부 해역의 해저지형에서는 소규모의 움푹 패인 지형들이 나타나는데 이는 독도 형성 후 나중에 생성된 소규모 분화구의 흔적들로 추정된다. 독도 정상부 해역은 주로 암반이 많이 분포하지만 곳곳에서는 모래 퇴적층들도 나타나는 것을 볼 수 있다. 독도 화산체 정상부에는 계단형의 경사면들이 나타나는데 이는 제4 기에 나타난 해침, 해퇴 등 해수면변화에 의해 만들어진 해저단구로 유추되며, 지역별로 차이가 있기는 하지만 주로 약 30 m, 60 m, 80 m 및 약 100 m의 수심대를 위주로 하여 몇 개의 주요 해저단구가 나타나는 것으로 판단된다. 자기이상도 및 아날니틱신호도를 살펴보면 수면 위 독도에서 연장되는 북동 및 북서쪽의 이상대들은 화구륜의 잔해로 예상되는 암반들의 위치와 유사하게 나타난다.

무인항공기는 새로운 형태의 무기체계 또는 군용항공기로 발전하고 있다. 특히, 미국은 지난 2001년 9.11테러 이후 테러와의 전쟁을 선포하고 무인항공기를 이용하여 테러집단에 대한 공격을 함으로써 전쟁의 효율성과 효과성을 높이고 있다. 이같은 무인항공기가 '비용없는 전쟁' 이라는 목적에 부합할 수 있으나, 한편으로는 국제법 또는 전쟁법에 합치하는가 하는 문제에 대해서는 많은 논란이 일고 있다. 앞에서 무인항공기의 개념과 전쟁법에 합치여부 그리고 영공침범문제 등에 대해서 쟁점별로 검토하였다. 검토결과 무인항공기는 무기가 아닌 항공기로 분류가 가능하다고 판단된다. 무인기 사용과 관련하여 문제가 되는 것은 관습 전쟁법과 성문 전쟁법에 기초한 군사적 필요성, 차별의 원칙, 비례의 원칙, 인도적 원칙 등이다. 특히, 무인기 사용과 관련하여 가장 크게 논란이 되는 부분은 비례의 원칙이다. 비례의 원칙은 기대되는 군사적 목표달성과 이에 따라 야기될 손해간의 균형을 요구한다. 이는 기본적으로 재산이나 시민에게 부가적인 손해를 발생시키는 군사력 사용을 금지하는 것이다. 즉, 비군사적 목표 또는 비전투원에 미치는 부수적 효과가 기대되는 군사적 이익을 명백히 초과하는 때에는 공격이 금지된다는 점이다. 이러한 원칙에 비추어 볼 때 무인기에 대한 비례성의 원칙의 합치여부에 대한 조금 더 신중하고 세밀한 검토가 이루어져야 할 것이다. 그리고 무인항공기에 의한 영공침범시 대응과 관련하여 조종지 타격이 전쟁법에 합치하는가 하는 데 대해 논란이 있는 바, 현재에는 무인항공기가 감시, 정찰 임무수행과 공격임무 수행에 대해서 구분하는 경향이 있다. 따라서 감시, 정찰 임무를 주로 하는 무인항공기에 대해서는 조종지 타격을 하는 것은 많은 제한점이 있으나, 공격임무를 띄는 무인항공기에 대해서는 조종지 타격이 가능하다는 것이 다수설이다. 앞으로 전쟁은 제4세대 전쟁 또는 사이버 전쟁이라고 불리어지는 새로운 형태의 양상이 될 것이다. 특히, 무인항공기와 같은 '최소 비용'으로 '최대의 효과'를 달성하려는 전쟁형태가 될 것이다. 따라서 여기에 대한 인도주의적, 전쟁범적인 연구가 필수적으로 이루어짐으로써 인류의 평화적인 발전에 기여해야 할 것이다.

Clinical practice in nursing education provides an opportunity for students, through the process of ap-plying theoretical knowledge to practice, and to learn nursing skills as well as being socialized into nursing and as such decrease the reality shock of actual nursing practice. Because of a shortage of nursing faculty, the job of achieving the objectives of the clinical practice had been turned over to the head nurses. This resulted in many problems, such as, unclear location of responsibilities and inadequate feedback from head nurses. Therefore this study was done to introduce and evaluate the use of preceptors as a way to minimize the above problems, and to maximize the achievement of the clinical practice objectives. Using an adaptation of Zerbe's (1991) three-tiered team model, clinical practice was done using a preceptor, a head nurse and a clinical instructor, each with different and well defined roles. The subjects of this study were 67 senior students of the College of Nursing of Y University in Seoul whose clinical practice in adult nursing was carried out between May 1, 1994 and December 8, 1994. There were 22 preceptors who had at least two years of clinical experience and who were recommended by their head nurses. They were given additional education on the philosophy and objectives of the College of Nursing, on communication skills, on the theory and practice of education, and on nursing diagnosis and education evaluation. The role of the preceptor was to work one-to-one with students in their practice. The role of the head nurse was to supervise and evaluate the preceptors. The role of the clinical instructor was to provide the education program for the preceptors, to provide ad-vice and suggestions to the preceptors and to maintain lines of communication with the college. With each of these roles in place, it was thought that the effectiveness and efficiency of the clinical practice could be increased significantly. To evaluate the effectiveness of the preceptorship, the three - tiered model, Lowery's Teacher Evaluation Opinion Form translated and adapted to Korea was used to measure student statisfaction. The Clinical Practice Compentency Evaluation Tool developed by Lee et ai was also used to measure student competencies. The results of this study are as follows 1. The satisfaction with clinical practice was higher with the introduction of the perceptors than it was before they were used. (t=-5.96, p=<.005) 2. The clinical practice competencies were higher with the introduction of the preceptors than it was before they were used(t=-5.l3, p<.005) 3. In order to analyze areas not measured by the quantitative tools additional analysis of the open questions was done. The results of this analysis showed that : 1) The students felt positive about their sense of security, confidence, handling of responsbility, and being systematic. They also felt positive about improvements in knowledge, opportunities for direct care, and socialization. 2) The students felt negative about the technical part of their role, lack of knowledge by the preceptor, unprofessional attitudes on the part of the preceptor, difficulty in the role of the professional nurse(student). 3) The preceptors felt positive about their responsibility, motivation, and relationship with the college. 4) The preceptors felt negative about their bur-den. Introduction of the preceptorship model will lead to change and improvement in the negative factors discussed above, solve problems in the present clinical education system, increase continuity in the education of the students, help with socialization of the students and motivation of the preceptors to up-grade their education and increase their confidence. These objectives must be obtained to further the development of professional nursing, and thus, making the preceptorship a reality is our job for the future.

This study was conducted to examine beauty shop workers' views of job. Data were collected from the workers in Seoul, Daegu, Pohang, Junjoo, and Kimhae from June 1, 2000 to August 31, 2000. The results of this study are summarized as follows. 1. According to general characteristics of the subjects, 28,7% of them was female; 94.2% 'specialized in hair'; 46.4% 'below twenty nine years old'; 47.1% 'married'; 59.7% 'highschool graduate'; 33.9% 'worked for below three years'; 28.5% 'monthly income of five hundred thousand to nine hundred ninety thousand won'; 62.3% 'working for above twelve hours a day' ; 41.0% 'above five workers' ; 40.6% 'working in city'. 2. 54.8% of the respondents thought that they were in good health. 76.3% of them smoked and 54.8% drank. 62.8% of them did not exercise and 78.7% was under stress. 61.5% responded that they chose the job because of its possibility of professional vocation. 91.0% of them obtained the beauty skill from beauty schools. 3. Among the factors which influenced job satisfaction, 'stable job and life security' was highest(43.9%), while 'interest in the job and amount of pay' was lowest(3.2%). 'Personal ability and use of originality' was 19.4% and 'harmonious relationship with fellow workers' was 18.1%. 'Job environment' was 7.1% and 'harmonious relationship with higher workers' was 4.5%. 4. The level workers' view of job was $113.8{\pm}17.3$ points on the basis of 150 points. On the basis of 75 points, each item showed it points in order of self-development($22.3{\pm}3.8$), service for customers($20.1{\pm}3.1$), vocational mission($15.6{\pm}3.1$), harmony with the others($18.9{\pm}3.5$), working environment($18.6{\pm}3.6$), and working condition($14.3{\pm}5.1$). 5. Among the reasons why they considered leaving the job, 24.0% of them considered it because they could not free time, while 15.4% considered it because undesirable living environment or long distance from home. 15.0% thought it because they could not receive proper treatment as much as they worked and 12.8% thought they overworked. 6. When they move into new working places, they consider such factors as good working environment(24.1%), good place to open their own beauty shops(16.7%), good beauty shop to learn beauty skill(15.6%), chance to have job training(9.5%), and close place from home(9.0%). 7. 40.6% of the respondents wanted to leave the job, while 32.3% of them did not want to leave the job. The intention of leaving the displayed significant difference in the variables of age, working period, monthly income, marital status, the number of workers, location of the shop, rank, and reason of selecting the job. 8.

해상에서 발생하는 유출유 사고는 피해 최소화를 위해서 신속한 현황 정보 수집이 필수적이며, 인공위성은 해상에 유출된 기름을 탐지하는데 매우 유용한 도구이다. 최근에 활용 가능한 인공위성 수가 급속하게 증가함에 따라, 사고발생 이후 준실시간 수준의 해상 유출유 현황 정보 생성이 가능해졌다. 본 연구에서는 2021년 4월 27일 중국 칭다오항 앞바다에서 발생한 심포니호 기름 유출사고를 대상으로 다종 인공위성 영상을 이용하여 기름 유출 면적을 산출하였다. 특히, 2 m 공간해상도 정보 획득이 가능한 고해상도 상용 인공위성 영상을 이용하여 기름유출 면적 산출의 정확도 향상 가능성을 평가하였다. 4월 27일부터 5월 13일까지 Sentinel-1, Sentinel-2, LANDSAT-8, GEO-KOMPSAT-2B (GOCI-II) 및 Skysat 위성영상을 수집하였으며, 기상조건을 고려하여 탐지 가능한 5장의 영상을 대상으로 유출유 탐지를 수행하였다. 유출된 기름은 사고발생 지점으로부터 남서-북동 방향으로 확산하면서, 외해에서 육지 쪽으로 이동하였다. 이러한 이동 경향은 Skysat 영상에서 확인이 가능하였으며, 사고 위치로부터 기름 입자의 이동예측을 수행한 결과와 유사하게 나타났다. 고해상도 인공위성 영상 탐지결과 및 이동예측 결과를 이용하여, 5월 1일 Sentinel-1A 영상에서 사고지점 북쪽 해역의 패치는 유사 기름으로 추정하였다. 이러한 오탐지를 제거한 결과 유출유 면적은 사고발생 후 선형적으로 증가하는 경향을 나타냈다. 본 연구 결과는 향후 고해상도 광학위성의 사용이 유출유의 분포 면적을 더욱 정확하게 산출함을 보여주었으며, 해상유출유 대응 과정에서 효율적인 방제계획 수립에 기여할 것으로 판단된다.
