The purpose of this study was to analyze the kinematic variables when Uchi-mata(inner thigh reaping throw) performing by Kumi-kata(engagement position, basic hold) types A, B(A: grasping part-behind neck lapel, B: chest lapel) in Judo with three dimensional analysis technique DLT method by videography. The subjects were four male judokas who have been training in Yong-In University(YIU), on Korean Representative level and Uchi-mata is their tokui-nage(favorite technique), the throwing form was filmed on two S-VHS 16mm video camera( 30frame/sec. Panasonic). Kinematic variables were temporal, posture, and COG. The data collection was performing by Uchi-mata. Six good trials were collected for each condition (type A, B) among over 10 trials. The mean values and the standard deviation for each variable were obtained and used as basic factors for examining characteristics of Uchi-mata by Kumi-kata types. The results of this analysis were as follows : 1) Temporal variables The total time elapsed(TE) by Uchi-mata of types A, B were 1.45, 1.56 sec. respectively. Types A shorter than B. 2) Posture variables In performing of Uchi-mata, the range of flexion in type A, left elbow was $45^{\circ}$ and B was $89^{\circ}$ from Event 2(E2) to Event 6(E6). Type A and B were quite different in right elbow angle in Event1(E1). Left shoulder angle of type A was extended and type B was flexed in E4. Both types right shoulder angles were showed similar pattern. Also both hip angles(right/left) were showed similar pattern. When type A performed Uchi-mata the knee-angle of supporting foot showed $142^{\circ}$in the 1st stage of kake phase[KP], and extended to $147^{\circ}$in the 2nd stage of KP. And the foot-ankle angle of supporting foot showed $83^{\circ}$in the 1st stage of KP, and extended to $86^{\circ}$in the 2nd stage of KP. moreover, The knee angle of attacking foot showed $126^{\circ}$in the 1st stage of KP, and extended to $132^{\circ}$in the 2nd stage of KP, and the foot-ankle angle of attacking foot showed $106^{\circ}$in the 1st stage of KP, and extended to $121^{\circ}$in the 2nd stage of KP. When type B performed Uchi-mata the knee-angle of supporting foot showed $144^{\circ}$in the 1st stage of KP, and extended to $154^{\circ}$in the 2nd stage of KP. And the foot-ankle angle of supporting foot showed $83^{\circ}$in the 1st stage of KP, and extended to $92^{\circ}$in the 2nd stage of KP. moreover, The knee angle of attacking foot showed $132^{\circ}$in the 1st stage of KP, and extended to $140^{\circ}$in the 2nd stage of KP, and the foot-ankle angle of attacking foot showed $103^{\circ}$in the 1st stage of KP, and extended to $115^{\circ}$in the 2nd stage of KP. During Uchi-mata performing, type A showed pulling pattern and type B showed lift-pulling pattern. As Kumi-kata types, it were different to upper body(elbow, shoulder angle), but mostly similar to lower body(hip, knee, ankle angle) on both types. 3) C. O. G. variables When the subjects performed Uchi-mata, COG of type A, B up and down in vertical aspect was 71cm, 73.8cm in height from the foot in the 2nd stage of KP. As Kumi-kata types, it were different on medial-lateral direction aspect but weren't different in Kuzushi phase on vertical direction aspect.

In the present age dominate by both cer-taingty of 1% and uncertainty of 99% 'Fuzzy thinking' of Bart Kosko that is the way to solve the problems by the scientific way through a worldview of Buddhism or Taoism greatly prevails around the world over 'Lateral greatly prevails around the world over 'Lateral thinking' and the authenticity or the right and-wrong of the uncertainty which is the thinking way to find the answer of the problems of illogical way of Edward de Beno against the western vertical thinking were Concurrently fashion designers over the world also adopt the oriental elements. But there exist differences of thoughts between the orient and the occident. And they have dif-ferent thinking way of aestheticism and references of the value on the beauty. Not only beauty but the view through the mind as intuitional thought in which not only the rec-ognition of sense but also the rationalism and the naturalness play key role. The aesthetic sense in the orient contains both the truth and virtue. 2) The beauty of the mean It's from the thought of neutralization of Confucius. The mean or moderation state which in harmony with ethical virtue and aes-thetic beauty is the ideal and is the ultimate. Therefore the thought of Confucian is the creativity in which the balance and the har-mony is most important. Fashion design is also one of the representation of the mean because the spirit of the designer is harmonized for-mlessly with the object of the model of the fashion design. 2) The beauty of skillfulness It indicates the Taoism of Lao-tzu and Chuangtzu. It takes a super-artistic declar-ation that human can feel and recognize the color of colorlessness the sound of sound-lessness and the taste of tastelessness. The thought of arts affected by Taoism is 'ad-vanced age' called the beauty of skillfulness. The view of arts of lao-tzu takes the beauty of cosmos and the nature as a standard. Es-pecially the beauty of inactivity is recognized by the linkage between the beauty and the ugliness. And these things appear in fashion design as a design element such as humor or exaggeration. 3) The beauty of non-dualism It is thought of Buddhism that all evil passions of worry occur form the opposition in dualism. Finally this thought leads to that everything is consistent and truth is only one from the point of view that virtue and vice has on linkage that is 'no virtues no vices' and 'one with two, two, with one, one is not two' A big tendency like this became the root forma-tion of the thought of the oriental arts. 3. Characteristics of the oriental aesthetic sense on the present fashion design 1) The formation of the fashion design on the oriental elements In the picture-incantation which was a representation of an era when the thought of 'cosmic dual forces' dominated the basic polygons of 'a circle square triangle' means both 'one two three' and 'the negative positive mean' of cosmic elements. From this point of view the was of planner cutting in the Orient is dif-ferent from that of the Occidental which is in three-dimensional. The planner polygon type of the cut-pieces comes to have the meaning of the three-dimension when they consist of a suit that has the combination of each cut-piece. This shows the consistency with the principle of cosmos creation of Taoism that one is two two is three and three is every-thing. 2) The coloring and the symbolic represen-tation of the fashion design on the orien-tal elements The sense on the colors in the Orient from the thought of 'the cosmic dual forces and the five elements' is not the experi-enced from the knowledge but contains the consideration of philosophy Five-primary-color representing compass directions Blue(East) Red(South) Yellow(Center) White (West) and Black (North) is called ' the posi-tive' for this five-primary-color secondary-color which comes from the compound of the primary colors is called 'the negative' The thought of 'the cosmic dual forces and the five elements' is also an theory containing the natural order of the cos-mos and this shows the perceptional differ-ence that they are not conceptual but to be recognized and fell directly. A thought of Buddhism which is 'Colors are colorlessness and Clolorlessness are color's proves that. 3) The pattern and symbolic representation of the fashion design on the oriental elements The pattern as a visual style is a figure of symbolic representation which adopt the mental and physical world of human and are the compo-sition of artistic revelation of the human nature and the religous thought of incantation. Es-pecially the symbolic representation of the oriental thought of Confusion. Buddhism and Taoism There are patterns such as plants aminals the oriental four gods and geometry. From the above it's the time toward the 21'th century when the world is constructing one global area and one historical zone. And the exotic mood of the Orient represented in the fashion which doesn't make the common feeling in general does not cease to develop only to express the visual modeling but also adopts the thought religion and the art which are the root of the Orientail and contains inherent willing of modeling.

INSTRODUCTION Service quality is, unlike goods quality, an abstract and elusive constuct. Service quality and its requirements are not easily understood by consumers, and also present some critical research problems. However, quality is very important to marketers and consumers in that it has many strategic benefits in contributing to profitability of marketing activities and consumers' problem-solving activities. Moreover, despite the phenomenal growth of medical service sector, few researchers have attempted to define and model medical service quality. Especially, little research has focused on the evaluation of medical service quality and patient satisfaction from the perspectives of both the provider and the patient. As competition intensifies and patients are demanding higher quality of medical service, medical service quality and patient satisfaction has emerged as a critical research topic. The major purpose of this article is to explore the concept of medical service quality and its evaluation from both nurse and patient perspectives. This article attempts to achieve its purpose by (1)classfying critical service attibutes into threecategories(satisfiers, hygiene factors, and performance factors). (2)measuring the relative importance of need criteria, (3)evaluating SERVPERF model and SERVQUAL model in medical service sector, and (4)identifying the relationship between perceived quality and overall patient satisfaction. METHOD Data were gathered from a sample of 217 patients and 179 nurses in Seoul-area general hospitals. From the review of previous literature, 50 survey items representing various facets of the medical service quality were developed to form a questionnaire. A five-point scale ranging from "Strongly Agree"(5) to "Strongly Disagree"(1) accompanied each statement(expectation statements, perception statements, and importance statements). To measure overall satisfaction, a seven-point scale was used, ranging from "Very Satisfied"(7) to "Very Dissatisfied"(1) with no verbal labels for scale points 2 through 6 RESULTS In explaining the relationship between perceived performance and overall satisfaction, only 31 variables out of original 50 survey items were proven to be statistically significant. Hence, a penalty-reward analysis was performed on theses 31 critical attributes to find out 17 satisfiers, 8 hygiene factors, and 4 performance factors in patient perspective. The role(category) of each service quality attribute in relation to patient satisfaction was com pared across two groups, that is, patients and nurses. They were little overlapped, suggesting that two groups had different sets of 'perceived quality' attributes. Principal components factor analyses of the patients' and nurses' responses were performed to identify the underlying dimensions for the set of performance(experience) statements. 28 variables were analyzed by using a varimax rotation after deleting three obscure variables. The number of factors to be extracted was determined by evaluating the eigenvalue scores. Six factors wereextracted, accounting for 57.1% of the total variance. Reliability analysis was performed to refine the factors further. Using coefficient alpha, scores of .84 to .65 were obtained. Individual-item analysis indicated that all statements in each of the factors should remain. On 26 attributes of 31 critical service quality attributes, there were gaps between actual patient's importance of need criteria and nurse perceptions of them. Those critical attributes could be classified into four categories based on the relative importance of need criteria and perceived performance from the perspective of patient. This analysis is useful in developing strategic plans for performance improvement. (1) top priorities(high importance and low performance) (in this study)- more health-related information -accuracy in billing - quality of food - appointments at my convenience - information about tests and treatments - prompt service of business office -adequacy of accommodations(elevators, etc) (2) current strengths(high importance and high performance) (3)unnecessary strengths(low importance and high performance) (4) low priorities(low importance and low performance) While 26 service quality attributes of SERPERF model were significantly related to patient satisfation, only 13 attributes of SERVQUAL model were significantly related. This result suggested that only experience-based norms(SERVPERF model) were more appropriate than expectations to serve as a benchmark against which service experiences were compared(SERVQUAL model). However, it must be noted that the degree of association to overall satisfaction was not consistent. There were some gaps between nurse percetions and patient perception of medical service performance. From the patient's viewpoint, "personal likability", "technical skill/trust", and "cares about me" were most significant positioning factors that contributed patient satisfaction. DISCUSSION This study shows that there are inconsistencies between nurse perceptions and patient perceptions of medical service attributes. Also, for service quality improvement, it is most important for nurses to understand what satisfiers, hygiene factors, and performance factors are through two-way communications. Patient satisfaction should be measured, and problems identified should be resolved for survival in intense competitive market conditions. Hence, patient satisfaction monitoring is now becoming a standard marketing tool for healthcare providers and its role is expected to increase.

Nowerdays, the increase of traffic accidents and old age population make the Femoral Neck Fracture(FNF) patients increase. By the improvement of education and standard of living the patients demand better medical service than before. This study is designed to give practical help for the FNF patients by observing their hospital life and establish practical nursing strategies for the FNF patients. For these purposes the Ethnographic Participant Observation was adopted. By this study is focused on the hospital life patient's view. For this end, the field study adopted orthopedic ward in the C University Hospital with 400 beds in Seoul. The object patients of the study were twelve patients. The patients experienced five stages : Embarrassment, Conflict, Stability, Independent, and Extension Stage. The findings and prepared nursing strategies are stated as follows. First, in the Embarrassment Stage they suffered embarrassment, anxiety, pain, they could not do ordinary things. The patients who accidental fractures had anxiety from unfamiliar tests and from hospitalization itself. They lamented that they could not ordinary things, and do nothing but obeying the hospital, and endure the pain. They recognized the changed environment and resigned themselves to life in the ward. In this stage, full openness by the nurses is needed. Second, the attribute of the Conflict Stage were conflict, fear, curiosity, belief, reflection. When they sign the consentment form, they experience conflicts about the possibility of complication, fear of recovery from anesthesia, curiosity about the operation procedure, post - operation state, reflection on their past life, and promise to care for their family members after discharge and keep their religious life faithfully. And they accepted the operation depending on God, believing in modern medicine, and the surgeon. Asking for their changed informations, they expected positive results from the operation. In this stage, an empathic attitude by the nurses is needed. Third, the attribute of the Stability Stage were relief, gratitude, difficulty with excretion, and pain. When they awoke from anesthesia, they felt relief because of a the end of the operation, but they experienced extreme pain, difficulty of excretion in bed. They accepted the changed environment and expected recovery. In this stage, support by the nurses is needed. Fourth, the attributes of the Independence Stage were freedom, exercise, nurturing, anxiety, and discomfort. When they ambulated and exercised, they experienced freedom. They showed exhibited weakness of the digestive organs and discomfort hospital's space, structure, and facilities, the delay of medical certificate issue the lack of prompt response by the medical agents. They ate nurturious food and felt anxiety on the end of hospital life and returning to their ordinary life. They showed the independence of overcoming their environment by increasing exercise and expected their discharges. In this stage, respect by the nurses is needed for the patients to, overcome their environment and prepare for their independence. Fifth, the attributes of the Extension Stage were pessimism, isolation, dissatisfaction, and pain. Accompanied injury and old age made their ward life extend to over seven weeks. They exhibited weariness, melancholy, skeptisis, general pessimistic feeling, and desperation caused by their isolated life. They experienced the digestive discomfort caused by the prolonged medication and psycological pain caused by long-time hospitalization. As a, result, their dissatisfaction on the human, physical, and systematic environments had been increased. They acquired critical power and sought for something to do spending their time. They expected vaguely about the returning of their ordinary life. In this stage, counseling is needed by the nurse to overcome positively their psychological, social, and physical problems. The process of the FNF patient's ward life starts from the dependent state, when they are hospitalized, and gradually progresses to self-fulfillment in order to keep independent life. As a result, the FNF patients showed "Response in Challenge" or "Adaptation in Conflict" through their experiences of social, physical, and psychological difficulties.

본 연구는 소면적 재배작물인 산마늘을 대상으로 tebuconazole 및 fludioxonil의 잔류특성을 조사하여 잔류허용기준(MRL) 및 안전사용기준 설정을 위한 자료로 활용하고자 수행하였다. Tebuconazole 20% 액상수화제 및 fludioxonil 20% 액상수화제 농약을 기준량과 배량의 농도로 토양관주처리한 후, 15, 30, 45일차에 시료를 채취하여 분석하였다. 두 약제 모두 dichloromethane을 이용하여 분배하였으며, SPE-Silica cartridge와 SPE-$NH_2$ cartridge를 사용하여 정제한 후, GC/NPD를 이용하여 분석하였다. Tebuconazole과 fludioxonil의 회수율은 각각 108.8~119.5%, 91.3~104.8%였으며, 이 때의 분석검출한계는 모두 $0.01mg\;kg^{-1}$이었다. 산마늘 중 tebuconazole의 잔류량은 <$0.01{\sim}0.12mg\;kg^{-1}$이었으며, fludioxonil의 경우 $0.01{\sim}0.09mg\;kg^{-1}$이었다. 두 약제의 잔류량으로부터 산출한 ADI 대비 식이섭취율(% ADI)은 각각 17.44%, 25.75%로 산마늘 중 tebuconazole 및 fludioxonil에 대한 ADI 대비 식이섭취율(% ADI)은 80%를 초과하지 않으며, 식이를 통한 두 약제의 노출 위험도는 안전한 수준인 것으로 판단된다. 이에 따라 tebuconazole 20% 액상수화제 및 fludioxonil 20% 액상수화제는 산마늘의 병해를 방제하는데 활용할 수 있으며, 잔류농약 문제를 효율적으로 관리할 수 있을 것이라 판단된다.

목 적: 용적변조회전 방사선치료는 겐트리 회전과 다엽콜리메이터, 선량률이 연동되어 진행되며 치료 중 선량 전달의 중단이 발생한 경우 겐트리와 다엽콜리메이터가 최초위치부터 다시 동작하여 정지된 지점부터 선량전달이 재개된다. 본 연구는 용적 변조회전 방사선치료의 치료 중단과 재 진행에 따른 선량전달의 오차를 분석하고자 하였다. 대상 및 방법: 10명의 환자를 대상으로 전산화치료계획시스템(Eclipse V10.0, Varian, USA)을 이용하여 용적변조회전 방사선 치료 계획을 수립하였다. TRILOGY (Varian, USA)의 6 MV 선속을 이용하여 계획된 선량을 이차원 배열 검출기와 CUBE (IBA dosimetry, Germany)팬텀에 조사하였다. OmniPro I'mRT system (V1.7b, IBA dosimetry, Germany)을 통해 4회에 걸쳐 일반적인 선량전달의 일관성을 평가 하고 선량 전달의 중단 또는 도어 인터락 발생으로 인해 선량 전달이 중단되고 최초지점부터 다시 시작되어 조사되는 경우와 비교하여 감마지수(Gamma index)의 변화를 분석하였다. 결 과: 선량 전달이 정상적으로 이루어진 경우에 각각의 감마 평균 신호 값의 차이는 0.1로 나타났고, 선량 전달의 중단이 발생한 경우 0.128로 나타났으며 도어 인터락의 경우 0.141로 나타났다. 각각의 경우 감마 표준편차 값의 차이는 0.071, 0.091, 0.099로 나타났고, 감마 최대값의 차이는 0.286, 0.379, 0.413으로 나타났다. Gamma pass rate (3%, 3 mm)는 허용 오차 범위를 만족하였고, T검증 결과 95% 신뢰구간에서 P-value가 0.05 미만으로 유의한 차이를 보였다. 결 론: 본 실험에서 치료 중 선량 전달의 중단 및 재시작에 관한 정확성을 평가해 본 결과 통계적으로는 차이가 있으나 임상적으로 허용 오차 범위이내로 문제가 없다는 것을 알 수 있었다. 그러나 겐트리와 다엽콜리메이터, 선량률의 연동으로 정확성이 요구되는 치료방법인 만큼 선량적인 측면에서 치료 중단에 따른 차이는 간과할 수 없다. 그러므로 갑작스러운 치료 중단 상황이 발생한 경우 추가적인 정도관리 절차를 통해 정확한 선량평가가 이루어져야 할 것으로 사료된다.

만화가 아동에게 미치는 접근성과 영향은 크다. 만화는 글과 그림으로 정보를 전달하는 매체이기에 어느 매체보다도 쉽게 아동에게 다가가는 특성이 있다. 특히 이야기를 들려주거나 읽어주는 방식에서 나아가 보여주는 방식이라는 점에서 아동들에게의 접근성은 어느 매체보다 뛰어날 수밖에 없는 것이다. <만화로 보는 그리스 로마 신화>는 주 독자층이 아동이다. 글로 읽는 신화가 아닌 만화로 보는 신화이기 때문에 아동에게 쉽게 수용되는 특징이 있다. 하지만 신들이 보여 주는 형태는 비윤리적인 표현들로 가득하다. 모자의 근친혼, 남매의 근친혼, 조카와의 근친혼 및 혼외정사의 성적 표현은 비윤리적인 경향이 강하여 아동에게 부정적인 영향을 미칠 수 있다. 제우스는 바람피우는 행위를 자주하며, 혼외정사에 의하여 생긴 제우스 자녀에 관한 이야기들이 자주 등장한다. 독자가 성인이라면 이성적 판단에 의한 가치 기준이 서 있지만, 아동은 옳고 그름의 이성적 판단이 부족하기 때문에 의문이 있더라도 그대로 수용하기 쉽다. 아동의 무비판적인 관찰학습에 대한 대안으로서, 작가의 개입을 통해 아동이 올바른 가치관 형성을 할 수 있게 연출할 필요가 있다. 아동을 독자로 하는 교양만화나 학습만화에서 비윤리적이거나 성적 표현을 사용할 수밖에 없는 경우에는 몇 가지를 기준으로 삼아 만화의 스토리와 연출을 할 수 있을 것이다. (1) 이야기를 들려주는 등장인물을 통해 비윤리적인 내용이나 성적 표현의 경우, 현재에는 수용할 수 없는 것이라는 분명한 표현을 보이는 것이 중요하다. 아동의 관찰학습에 있어서 벌은 즉각 주어지는 것이 효과적이므로 교양 학습만화에서 학습효과를 높이기 위하여 아동에게 잘못된 학습이 될 수 있는 표현에는 작가가 적극적으로 개입할 필요가 있다. (2) 이야기를 들려주는 등장인물과 질문하는 아동의 대화를 통해 올바른 가치관 형성을 할 수 있게 연출하여야 한다. 본 연구는 현 시점에서 아동에게 부정적 영향을 미칠 수 있는 신들의 비윤리적인 표현을 분석하였으며, <만화로 보는 그리스 로마 신화>에서 아동의 사회학습에 미칠 수 있는 제우스와 신들의 성적 표현을 분석하는 것이 목적이다.

불균일 $CoO_x/TiO_2$ 촉매가 충진된 연속 흐름식 고정층 반응기 내에서 ppm 수준으로 수중에 존재하는 trichloroethylene (TCE) 제거반응을 수행하였으며, 가장 우수한 반응활성을 갖는 촉매의 결정구조와 표면화학적 특성을 분석함으로써 반응시간에 따라 분해활성이 전이영역을 보이는 원인을 규명하고자 하였다. $36^{\circ}C$의 반응온도에서 모델반응의 내부확산저항은 없었으며, $TiO_2$ 표면에 흡착에 의한 액상 TCE 제거정도는 무시할 수 있었다. 5% $CoO_x/TiO_2$ 촉매는 본 대상반응에 대하여 가장 우수한 활성을 갖는 것으로 나타났으며, 반응시간의 경과정도에 따라 TCE 분해효율이 점진적으로 증가하여 안정화되는 전이영역의 존재를 확인할 수 있었다. 반응 전 5% $CoO_x$ 촉매에 대한 XRD 패턴에서 담지체로 사용된 $TiO_2$에 의한 피크들 외에 새로운 피크가 관찰되었고, 5시간 이상 동안 반응한 후에 건조된 촉매의 경우에도 반응 전 촉매의 XRD 피크와 매우 유사하였다. $Co_3O_4$의 XRD 패턴들과 대조한 결과, 5% $CoO_x$ 촉매상에서 Co 화합물에 의해 야기되는 XRD 피크들은 $Co_3O_4$에 의한 것임을 알 수 있었다. 반응물에 노출되지 않은 5% $CoO_x/TiO_2$ 촉매에 대한 XPS 측정은 797.1 eV에서 Co $2p_{1/2}$에 대한 주피크와 함께 781.3 eV에서 Co $2p_{3/2}$에 대한 주피크가 관찰되어졌다. 반응 후 촉매의 경우에는 Co $2p_{3/2}$ 및 Co $2p_{1/2}$의 binding energy들은 각각 780.3과 795.8 eV에서 나타났다. 반응 전 후 촉매상에서 Co $2p_{3/2}$의 binding energy 차이는 1.0 eV이고, Co $2p_{1/2}$의 binding energy 차이는 1.3 eV이다. 표준 $Co_3O_4$에 대한 XPS 측정결과, 반응 후 촉매상에 존재하는 $CoO_x$는 $Co_3O_4$로 존재하고, 반응 전의 경우에는 이와는 다른 chemical state를 보여주었다. XRD 및 XPS 결과를 바탕으로, 촉매표면에 존재하는 $Co_3O_4$의 외부표면이 $Co_2TiO_4$와 $CoTiO_3$ 같은 $CoTiO_x$로 encapsulation되어 있는 모델구조를 제안할 수 있고, 이는 반응시간의 함수로 나타나는 촉매활성에 있어서 전이영역의 존재를 잘 설명할 수 있을 뿐만 아니라, XRD와 XPS에서 얻어진 촉매의 물리화학적인 특성을 잘 반영할 수 있다.
