Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

Today human needs for health promotion and maintenance are increasing. The nursing progression has a great responsibility for helping clients to practice good health behavior. self efficacy was found to be potent predictor in initiating and maintaining the health-related behavior. Therefore, the concept is important in nursig intervention for change of health behavior. The purpose of this paper was to analyze and clarify the meaning of the concept, self efficacy. This study used Walder & Avant's process of concept analysis. Critical attributes of self efficacy were : 1) positive perception of his won capability; 2) intrapersonal strength; 3) possibility of being learned; 4) individuality; 5) specificity; 6) generalizability. Antecedents of self efficacy consist of those facts that 1) new situation occurs; 2) individuals have needs to change the new situation; 3) there are some required actions in new situation. Consequences occurring as a result of self efficacy consist of those facts that 1) individual initiates the of failure; 5) cope with the situation; 6) controls the situation; 7) the level of self efficacy is enhanced; 8) the level of self-esteem is enhanced.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.

In this paper, we have implemented the new protocol, LB_UDP, that can be used for multimedia data transmission. The implemented LB_UDP can control a burst multimedia data and regulate traffic having a constant rate at regular intervals. LB_UDP protocol maintains the basic actions of UDP and controls bursty data using the Leaky Bucket algorithm. We have test a implemented LB_UDP in Linux Kernel. When traditional UDP was used, we could find that the data transmission rate changes variably. But when LB_UDP was used, we could find that the change of data transmission rate is a little. The designed LB_UDP can be used to transmit a multimedia data without network congestion.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

백혈구에 존재하는 과산화 효소를 이용하여 뇨 중 백혈구의 수를 간접적으로 측정하는 새로운 방법의 뇨 검사지를 개발하였다. 과산화 수소원으로서 포도당 산화효소와 포도당을, 색원체로서 tetramethylbenzidine을 처리하여 백혈구 측정용 뇨 검사지를 제조하였으며 검출한계는 10cells/㎕ (5 cells/hpf)이었다. 개발된 백혈구 측정용 뇨 검사지로 뇨를 분석하였을 때 뇨 1/㎕당 10-25cells의 백혈구가 존재할 경우에는 2분내에 연녹색을, 75-250 cells/㎕에서는 녹색을 보였고 500 cells/㎕ 이상에서는 녹청색을 보였다. 172명의 환자뇨를 대상으로 뇨중 백혈구 수치를 현미경 측정 결과와 본 연구에서 개발한 백혈구 측정용 뇨 검사지와 현재 수입 시판 중인 미국의 A사 제품과 B사 제품으로 분석 비교한 결과 좋은 상관관계를 보였다. 이와 같은 평가분석을 통하여 볼 때 본 연구에서 개발한 백혈구 측정용 뇨 검사지는 에스테라아제를 이용한 백혈구 측정용 뇨 검사지와 함께 뇨중 백혈구를 스크리닝 하는데 효과적임을 알 수 있었다. A new test strip to detect leukocytes using the myeloperoxidase in urine was developed. The reagent strip contains tetramethylbenzine, glucose and glucose oxidase. The detection limit was between 10 cells per 1㎕ urine(5 cells/hpf), showing greenish yellow color in the range of 10-25 cells/㎕, green color in the range of 75-250 cells/㎕, greenish blue color in the range of 500 cells/㎕. The result can be obtained within two minute. The performance of the new method was evaluated by comparing the results of microscopic examination and other commercial products. Good correlations were shown between the values obtained by our urine strip and those by other commercial products with 172 urine samples. The results were proven that new methods were useful as primary screening reagents to detect leukocytes in urine.

4 multinucleate and 7 mononuclear fungi were investigated for screening of high protease productive strains. The protease activity of mononuclear strains was generally greater than that of multinucleate strains. For acid proteinase, Aspergillus awamori AOK 1007 and Asp. oryzae shoyu 2 as mononuclear strains were selected in glucose-polypeptnoe medium. For acid carboxypeptidase, two mononuclear strains were screened as Asp. awamori AOK 1007 and Asp. usamii mut. shirousami AOK 1011 in glusose-sodium glutanate medium. In this result, mononuclear fungi appeared higher protease production than that of multinuclear fungi. So, mononuclear fungi may gave many merits to improve protease activity by using of mutation or cell fusion technology.
