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.

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.

Lovastatin(LV), one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid (Lovastatin acid. LVA). In order to optimize the assay procedure of LVA by high performance liquid chromatography(HPLC). solid phase extraction(SPE) method and protein precipitation method were employed for the pretreatment of plasma sample containing LV and LVA, and plasma sample was hydrolyzed under alkaline condition to transform all LV to LVA. Following pretreatment of plasma sample. 100ul of sample was injected onto a reversed-phase C_18 column and eluted with a acetonitrile-pH 3.0 phosphate buffer mixture(45:55 v/v) at a flow rate of 2.0ml/min. Ultraviolet detection was carried out at 238nm. It has been shown that all of LV in plasma was converted to LVA in vitro under alkaline condition. On SPE method, elution with acetonitrile-methanol mixture(75:25 v/v) indicated the highest recovery of LVA, but acid treatment of plasma sample before loading on SPE cartridge revealed little effect on recovery of LVA. Compared with two different pretreatment of plasma sample, SPE indicated better sensitivity and recovery.

본 연구는 자기자신의 대인관계특성을 이해하기 위하여 대인관계성향검사를 제작하는 것을 목적으로 한다. 이를 위하여 주로 남녀 대학생들을 지역별로 표집하여 수집된 자료를 예비검사(N=343) 하였다. 본 검사는 전국의 10개지역의 4년제 대학교와 전문대학의 남녀 대학생을 대상으로 하였고 최종 분석대상은 1531명이었다. 본 연구는 예비연구를 통하여 대인관계성향의 개념을 형성하는 차원을 요인분석을 통한 구인타당도와 내용타당도를 검증함으로써 대인관계성향 검사를 제작하였다. 최종검사의 문항은 요인분석 결과 8개 차원 91문항으로 나타났다. The purpose of this study was to investigate the construct validity of the interpersonal relations scale developed by factor analysis. The subjects of the pre- study were 343 college or university student randomly sampled and assigned. The subjects of main study were 1531 female and male college students and junior college students the 10 regions through out the country. Interpersonal Relations Disposition (IRDS) consists of 8 areas, there are Role disposition ares and Expressive areas - These major areas are further divided into eight sub-areas there are : Initiative - comformative, independant - non independant, responsibility - non responsibility, superiority - inferiority, agressive - non agressive, empathy - non empathy, mis trust - trust, competition - non competition.

기존의 학습자 평가 시스템은 교수자의 주관적인 관점과 견해에 의해 각 문항의 난이도가 결정되는 단점을 가지고 있다. 본 논문에서는 학습자의 개별 능력 평가가 가능하고 개인별 학습 수준에 적합한 문항을 난이도, 변별도 및 추측도를 이용하여 학습자에게 제공함으로써 개인별 문항 평가가 가능한 학습자 평가 시스템을 개발하고자 한다. 본 연구의 학습자 평가 시스템은 CAT 기법의 문항 반응 이론 중 3-모수 로지스틱 모델을 이용하여 개발한다. In existing the learner testing system, it has a weak point to determine differently the difficulty of each question which has been estimated by teacher's view and the subjective stand point. In this paper, we develops the learner testing system which supports the estimation of the individual ability of learner, provides the questions for suitable to the individual learner level, and able to estimate the question of individual that used by three parameters such as the difficulty parameter, discrimination parameter, and guessing parameter. Also, it is applied to three-parameters logistic model of IRT(Item Response Theory) for using CAT(Computer Adaptive Testing) technique.

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.
