Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

This Study was intended to present a fundamental materials for the self-evaluation of the Inchon Teachers College. Among the six areas which were divided by the Korean Counil for University Education (KCUE), this study tried to analyze the educational goal and objectives the curriculum, and the administration and finance of the college. The results of the study are the followings; 1. The goal and objectives a. It can be said that pursuit for realizing the general ideal, and the public relation for the goal belong to the low level. b. The goal and objectives are made by no consent of the whole members, and by no proper procedures. c. There is a tendency of no systematic relationship betweeh the goal and the objectives of the College. 2. The curriculum a. The curriculum of the College can be evaluated that it fairly well reflects the goal and objectives of the College, but the total credits, especially the credits of general course, are heavier than those of other teacher training institutes. b. according to the survey of the student they want the faculties (1) to prepare for the content of the lectures more intensively, (2) to lecture the content in accordence with the objectives of the instruction (3) and they also indicated that the questions and the discussions are not active during the lectures. c. The sequence of the intensive courese can be maintained, but there are some intensive courses where the characteristics of the elementary teacher training institute have not been considered. The administration and the finance a.No functional connection between the line and the staff organization seems to exist. b. The planning for the College development can be recognized, but the efficiency of its implementation seems to be low. c. The budget of the College seems to be managed unilaterally, and the criteria of the budget allocation are not clear.

This survey measured the levels of risk behaviors in six categories in high school students in Taegu, to collect basic data to develop school health policy and health promotion programs. The target population was high school students in Taegu. Out of 136,973 students, 1,853 were sampled through stratification of gender, class and grade. We used a 1999 version of the Youth Risk Behavior Survey of CDC, which was translated. Many high school students engaged in behaviors that will increase the likelihood of death or illness. Vocational high school students and male students were significantly more likely than general high sachool and female students respectively, to have risk behaviors in most categories except, physical inactivity. First graders were significantly more likely to have violence-related risk behaviors(<0.05) and second graders were significantly more likely to have depression (<0.05). Third graders were significantly more likely to be physically inactive(<0.01). Almost 70% of students rarely or never wore seat belt. Lack of safety practice was prevalent and significantly undiffered by gender, class and grade. 62.3% had recently drank alcohol, 31.8% had ever tried cigarrette smoking, 67.7% had unhealthy diets behaviors, 62.5% had a low level of physical activity and 5.4% had had sexual intercourse. Conclusion; A High percentage of high school students engaged in risk behaviors and some subgroups were exposed to significantly more risks. Particularly, vocational high school and male students were high risk subgroups.

Guidance is one of the most difficult of all educational subjects to discuss because of the past and continuing confusion and uncertainty concerning its nature and function. Our increasingly complex environment and awareness of individual differences make an attempt at guidance in the school inevitable. Ideally conceived, guidance enables each individual to know his abilities, interests, and personality traits, to develop them as well as possible, to keep them flexible in order to meet the demands of a fluid environment, to relate them his life goals and to clarify these goals, and finally to reach a state of complete and mature self-guidance as a desirable citizen of our democratic social order and of the world. In this context, the researchers attempt to investigate the problems of guidance in the elementary, secondary schools and university in Korea ever since guidance was introduced in Korea in 1957. And We tried to find out proper solutions to develop potentiality of each individual by way of guidance program from each school authorities. The contents of the study was summarized as follows: 1.to find out the theoretical background of guidance services in general 2.to investigate the actual condition of professional counselors in the each schools 3.to analize problems of guidance in the each school 4.to suggest the solutions of the problems in the each school 5.to illustrate the present status of counseling and method in elementary, secondary school and university. 6.to suggest the zele and duty of the counselor in school 7.to show the suggestions of policy making to promote the execution of guidance The findings and suggestions of this study were summarized as following items. 1.It is necessary to systematize professional counselor system for actualizing counseling activity and career guidance in the elementary school 2.It is required to assist administrative function and financial help for establishing counseling room in the elementary school 3.It is necessary to dis patch professional counselor in each school and required to utilize the counseling room for all students 4.It is required to regulate the system of counselor certificate and to be changed into inservice training for the temporary counseling training course employed so far. 5.It is suggested to install career information center to the each school and to advise to use them effectively. 6.It is necessary to execute standardized test such as intelligence, aptitude, personality test, interest, creativity, scholastic aptitude test, and vocational interest test in the school and to utilize them positively. 7.It is suggested to utilize the student guidance center in the university and to emphasize counseling service function by counselor. 8.It is necessary to establish student's suggestion box to each school and suggest to solve the problems which students ask for.

CORBA, which is a standard base of distributed object in distributed computing environment, suggests the method for clearly creating the demand for object defined on OMG and receiving it. Although CORBA appeared as the standard of distributed object and has played an important role in operating distributed object between different computer systems, distributed object computing has such fundamental problem as great demand by many clients an3 Server and the overload of network. CORBA is middle-ware technology to develop one distributed application program by connecting separately-developed distributed object in various platforms which are connected in, open communication network. With expansion of distributed application software scale and complex interface between distributed objects, this study defines object as group in the concept of aggregate in order to control efficiently and to be controlled as group by grouping multi-arranged object and suggests group object model in the side of controller for efficient control of distributed object.
