Surgical intervention in the posterior maxillary region requires detailed knowledge of maxillary sinus anatomy and the possible anatomical variations. This study evaluated the incidence, location of maxillary sinus septa by using radiographic (panoramic radiography and computed tomography) findings and comparison of panoramic radography with CT in antral anatomical variation. This study was based on data from 70 sinuses in partial dentate maxilla. The sample consisted of 61 patients(25 women and 36 men, with ages ranging between 19 and 77 years and a mean age of $49.4{\pm}11.3$ years) who were being treatment-planned to receive implant-supported restorations. First, the panoramic images were examined for the presence of antral septa by radiologist and examiner who don't know about CT findings. And incidence of antral septa was evaluated using an axial plane of CT image. The incidence of septa was compared between panoramic radiography and CT. The accuracy of the incidence was compared between radiologists and dentists. A total of 20 septa were found in 70 sinuses on CT image and the prevalence of one or more septa per sinus was found to be 28.6%. The assumed incidence of septa on panoramic radiography was $27.6%{\pm}2.2%$ in radiologist and $31.9%{\pm}5.8%$ in dentists. Erroneous diagnosis rate was 11.42% in radiologist and 15.96% in dentists. 40% of antral septa were located in the anterior(premolar) region, 30% of septa were located in the middle(first molar) and posterior(second molar) region separately. Prior to implant placement, it seems appropriate to consider panoramic radiography as a standard radiographic examination and periapical radiographs may be used to complete the findings in regions not sharply depicted in the panoramic radiograph. And cross-sectional imaging should be used in sites with severe bone loss and close proximity of the maxillary sinus.

Cultivation of competent manpower is recognized as one of the important factors in the development of fisheries as well as of other industries. For reference to the development of education of fisheries high schools in the Republic of Korea, the author carried out a study on the education in Japan. The reason is why the education on fisheries had been initiated in Japan and her educational system has played the role of a model for neighboring countries. Even though the education on fisheries tends to shrink a little in recent years by diffusing the unwilling tendency to engage in 3D (dirty, difficult and dangerous) jobs, there are fifty-one high schools educating fisheries in Japan. Thirty-eight of them are specialized fisheries high schools and the others are comprehensive high schools to put common course and fisheries course together. In the first step of study, the goal of education on fisheries, organization of department and arrangement of curriculum are analysed. 1. In the newly arranged curriculum which will come into effect from 1994, the goal of education on fisheries is set up as "By educating fundamental knowledge and technology on the production and circulation in the field of fisheries, have students understand the significance and role of fisheries, and so cultivate ability and active attitude to the development of fisheries". The goal means that the circulation of fishery products are regarded as important as the production itself, and active attitude to the development of fisheries is also stressed, different from the present goal. 2. Standard departments directed by the Government are set up as five-Departments of Marine Fishing, of Fisheries Engineering, of Information Communication, of Fish Culture, of Sea Foods. But they are actually organized and named by the founders of schools-local government. Then there are many unique-named departments and the management of schools are somewhat flexible according to the situation of local district. 3. Special subjects are revised to twenty-four in the new curriculum from twenty-two in the present curriculum. Among them the contents are widely revised in the subjects such as Introduction to Fisheries, Fisheries Engineering, Communication Engineering, Communication Technology, Fish Culture. On the other hand, five subjects such as Information Treatment on Fisheries, Information Technology on Fisheries, Subjective Study, Fisheries Economics, Circulation of Sea Foods are newly set up to meet the changing phase of the time.

대용량(High-throughput) 형태로 얻어진 cDNA 마이크로어레이 데이터에 다양한 데이터 마이닝 기법을 적용하면 서로 다른 조직에서 추출한 유전자의 발현정도를 비교할 수 있고 정상세포와 암세포에서 발현량의 차이를 보이는 DEG(Differently Expression Gene) 유전자를 추출할 수 있다. 이들을 이용하여 병을 진단할 수 있을 뿐만 아니라, 암의 진행 단계(Cancer Stage)에 따른 치료 방법을 결정할 수 있다. 마이크로어레이를 기반으로 한 대부분의 암 분류자는 기계학습 기법을 이용하여 암 관련 유전자를 추출하여, 이들 유전자를 총체적으로 이용하여 독립 샘플의 클래스(암, 정상)를 판정한다. 하지만 유전자의 발현량의 차이뿐만 아니라 유전자와 유전자의 상관관계의 변화가 질병 진단에 활용될 수 있다. 대부분의 질병은 단독 유전자의 변이에 의한 것이 아니라 유전자의 모듈로 이루어진 유전자조절네트워크의 변이에 의한 것이기 때문이다. 본 논문에서는 조건에 따라 특이적 관계를 나타내는 유전자 쌍을 식별하여, 이들 유전자 쌍을 이용한 유전자 분류 모듈을 생성한다. 분류 모듈을 이용한 암 분류 방법이 기존의 암 분류 방법보다 높은 정확도로 암과정상 샘플을 분류함을 보여주고 있다. 분류 모듈을 구성하는 유전자의 수가 상대적으로 적으므로 임상키트로의 개발도 고려할 수 있다. 향후 분류 모듈에 속하는 유전자의 기능적 검증을, GO(Gene Ontology)를 활용함으로서, 밝혀지지 않은 새로운 암 관련 유전자를 식별하고, 분류 모듈을 확대하여 암 특이적 유전자조절네트워크 구성에 활용할 계획이다.

This study was undertaken to identify the musculotendinous problems and contributing factors to those problems In students majoring in musical instruments in Korea. The data were collected from March 2, 1996 to March 31, 1996 from 261 music students in various geographical areas. The data were analyzed for descriptive statistics, t-test, chi-square using SPSS $PC^+$ program. The results of this study were as follows : 1. In a questionnaire survey of 261 music students, one hundred twenty five(47.9%) reported having had various musculotendinous symptoms. Twenty seven students among the those who had previous symptoms(21.9%) reported the present symptoms. 2. The experience rates of musculotendinous problems in keyboard players, string players and woodwind players were 50.3%, 48.2%, 33.3% respectively. 3. Most of the students practiced most intensively during their high school years and the musculotendinous symptoms began at the same period. 4. Pain, tenderness and stiffness were the most common symptoms, while paresthesia and motor dysfunction were rare. This indicates that most players had muscle tendinous overuse, while small number had nerve entrapment and motor dysfunction. 5. In past and present symptoms, string players experienced musculotendinous symptoms mainly in both sides of shoulders, lumbar area, left finger, and left wrist, while keyboard players experienced more symptoms in the right wrist, shoulder, fingers than left side. 6. The major contributing factors to the symptoms were weight of instrument, types of instruments, types of daily activities, duration of practice, and playing technique. 7 The most frequent treatment modalities for the symptoms were acupuncture or moxibustion, other alternative therapy such as heat compress and massage. Through this study it was found that the musculotendinous problems might be increased along with their career, due to lack of knowledge about preventive measures and patterns of health behavior seeking alternative modalities rather than professional consultation. Therefore, preventive measures that focus on playing habits such as duration of practice, frequency of rest and position while playing should be developed and taught to the students, their parents, and music educators. Doctors who are interested in this area should attempt to correct the position and posture while playing of the posture. And measures for reduction of loading of instrument weight should also be developed.

These days, the environment of hospital marketing is changing rapidly. The level of expectation and demand of patients have become greater and more diversified, and patients have more alternatives in selecting hospitals. The standard of hospital selection and the type of using hospital have been changed, and competition among hospitals has been accelerated due to the opening of the medical market through globalization. Accordingly, differentiation strategies are critical in hospital marketing. The quality of medical service oriented toward patient satisfaction becomes a strong strategic weapon to secure a hospital's competitive advantage. Therefore, marketing and communication strategies should be focused on patient-oriented, rather than hospital-oriented. Considering the changes in the hospital environment and the increase in the patients' expectation level, this study categorizes doctors' communication styles into four different ones: trust-type, professional-type, cooperation-type, and control-type. The effects of these communication styles on patient satisfaction were empirically examined. The moderating roles of the patient's characteristics and clinical characteristics between the doctors' communication styles and patient satisfaction were also investigated to find out managerial implications for hospital management. To achieve such goals, data were collected from patients of 12 general hospitals in Busan. The data were analyzed to test research hypotheses that examine 1) the relationships between doctors' communication styles and patient satisfaction, 2) the moderating roles of the patient characteristics and clinical characteristics in the research model, and 3) the impact of patient satisfaction on positive word-of-mouth and repurchase. The following summarizes the major results of this research. First, the data showed that patient satisfaction varied across doctors' communication styles. Trust-type style had the strongest impact on patient satisfaction while control-type style had the weakest influence on patient satisfaction. Professional-type style and cooperation-type style also had positive effects on patient satisfaction but the impact of the two are not statistically different. Second, significant differences in terms of patient satisfaction were found depending upon demographic variables such as gender, marital status, age, occupation, and education. Patient satisfaction, however, was consistent across varying income groups. Third, patients' medical insurance types were also related to patient satisfaction. It implies that a doctor may need to use different communication styles depending on a patient's medical insurance type. Fourth, out-patient and in-patient showed a different level of satisfaction with varying communication styles. Fifth, highly professional knowledge and strong control can influence patient satisfaction depending on the characteristics of the patient treatment field. Sixth, patient satisfaction were proved to have significantly positive effects on word-of-mouth and repurchase. The implications drawn from this study must be tempered by its limitations. First of all, the subjects used in this study were patients in Busan and small- and medium-size hospitals were excluded from the research. Therefore, future research should examine the research model by using a variety of hospitals and clinics throughout Korea. Another research agenda has to do with finding more determinant and moderating variables which will increase an explanatory power of the model. In short, this study may be the first empirical research that investigates the effects of doctors' communication styles on patient satisfaction. Interestingly enough, the results showed that each communication style had a unique impact on patient satisfaction. The findings from this research can be very useful in developing hospital marketing strategies.
