  • Behcet's disease (BD) is a systemic vasculitis characterized by recurrent oral and genital ulcers, and ocular inflammation, and which may involve the joints, skin, central nervous system and gastrointestinal tract. Although the exact pathogenesis for BD is not completely understood, it has been suggested that the disease is triggered in genetically susceptible individuals by environmental factors, such as microbial agents. It is noted that multiple genes, including MHC (major histocompatibility complex) and non-MHC genes, are implicated in the pathogenesis of BD. This study tries to determine whether IL-6 gene polymorphisms are associated with susceptibility to Behcet's disease in Koreans. Gene polymorphisms were typed by VNTR (variable number of tandem repeat), RFLP (restriction fragment length polymorphism), DHPLC (denaturing high performance liquid chromatography).There were no evidences for genetic association conferred by the IL-6prom polymorphism. However, significant differences in the IL-6vntr genotype and allele frequencies were found between patients with BD and controls. The IL-6vntr*C allele appeared to be an additional susceptibility gene to Korean BD. Further studies in other populations and gene are required to confirm these results.

  • In the azoospermic patients, there are many of undiagnosed factors related to genetic bases. Among them, Klinefelter's syndrome (47,XXY; KS) and Y-chromosomal microdeletion with normal karyotype(46,XY; YMNK) are the most frequent causes of male infertility. This research focused on the comparative analysis of YMNK (n = 66) and K5 (n = 30) patients suffered from male infertility in Korean population. We used the polymerase chain reaction (PCR) approach including 19 pairs of sequence-tagged site (STS) primers for detecting the Y-chromosomal microdeletion on AZFa, b, c regions, indicating that Y chromosomal microdeletions were almost evenly occurred in AZF all regions in Korean population. Comparative analysis indicated that 34.9% YMNK and 73.4% KS patients harbored the microdeleted Y-chromosome. It seems to be high instability of Y-chromosome in KS patients than that of YMNK infertility patients. Taken together, genome instability containing microdeletion could bring male infertility with the disturbance of normal spermatogenesis.

  • This study aims to verify the effects of the sewing practice class, developed for the cultivation of creativity and personality, the two qualities that the Korean Department of Education tried to emphasize in 2009 national curriculum. We conducted a single-group pretest-posttest experiment with the developed sewing practice class as a treatment. Results are as follows. First, the comparison results of before and after the developed sewing practice class showed that there were meaningful differences in creativity and its subfactors such as divergent thinking skill, problem solving ability, open-mindedness and patience. This is because in-class activities such as coming up with ideas by group discussion, creative activities and problem-solving experiences make the students be aware that they are the hosts of the class. It also affected their abilities of producing creative ideas and solving problems proactively. Second, the developed sewing practice class had an impact on students' personality and its subfactors like responsibility, diligence, consideration, communication skill, and collaborative ability. This practice class is based on personal activities which lead to the completion of the group assignment. This has not only emphasized individual responsibilities, but also highlighted the completion of group work and encouraged the flow of communication and cooperation among students. As a result, we concluded that this practice class helped nourish the participating students' personality.

  • A strength of BitTorrent, which is widely used for file sharing today, is due to its peer selection mechanism which is designed to encourage peers to contribute data. In the peer selection phase in BitTorrent, peers to upload the file in a swarm are selected by determining which peers upload the most to themselves. However, the number of peers to upload (i.e., number of unchoked peers) is fixed to four in its peer selection mechanism of BitTorrent, which yields inefficiency because the situation of the swarm may vary frequently (e.g., number of peers in the swarm, download rates, and upload rates). In this paper, we analyze the swarming system performance when the number of unchoked in BitTorrents is not static, but dynamic. For empirical investigation, we established a testbed in Seoul National University by modifying an open-source BitTorrent client, which is popular. Through our experiments, we show that an adaptive mechanism to adjust the number of unchoked peers considering the situation of the swarm is needed to improve the performance of BitTorrent.

  • In general, distribution board, panel board and motor control center can be installed over a wide area such as residence of group, building, schools, factories, ports, airports, water service and sewerage, substation and heavy industries that are used to supply converts the voltages extra high voltage into optimal voltage. There are electrical accidents due to rise of contact temperature, loose contact between busbar, deterioration of the contact resistance, over temperature of the busbars. In this paper, we designed and implemented the busbar joint and temperature measurement system, which can measure the joint resistance of busbar and loose connection between busbar using potentiometer and non-contact infrared sensor. The experimental results show that tightening the bolt and nut is fully engaged, resistance was decreased and maximum error range was 0.1mm. Also, the experimental result showed that the temperature at the contact area is increased from $27.3^{\circ}C$ to $69.3^{\circ}C$by the contact resistance.

  • The purpose of this study is to confirm how keeping a educational diary in which no feedback is given in the teaching practice in kindergartens affects a teacher efficacy and the educational belief of preschool teachers-to-be as well as the organizational health of kindergartens to practice according to the way teachers feel. With this aim, the study aimed at 34 seniors at the Department of Early Childhood Education in the four-year college in Chungnam. The study conducted this experiment using the nonequivalent control group pretest-posttest design, and carried out a $x^2$ analysis and a t-test according to the data. Concerning the research results, first, keeping a educational diary of teaching practice affirmatively affected a teacher efficacy. Second, it did not significantly affect a teacher's educational belief. Third, it did not significantly affect the organizational health of the kindergarten to practice according to the ways teachers-to-be feel. This study is meaningful in that keeping a reflective journal in which feedback by a guidance teacher for practice becomes the basic proposition may be replaced with the keeping of a diary of practice at the level of practicality. This means that a teacher's sense of efficacy may improve simply by keeping a educational diary of teaching practice without feedback by a guidance teacher.

  • COSPAS-SARSAT 시스템은 위성체와 지상 설비를 이용하여 항공기 또는 선박 등이 조난 시에 탐색구조(SAR: Search and Rescue) 활동을 도울 수 있도록 조난경보와 위치정보를 제공하는 시스템이다. COSPAS-SARSAT 서비스의 경우, 조난신호 접수에서 조난위치확정까지 평균 1시간 이상이 소요되고, 위치정확도가 수 Km 정도로 범위가 넓은 편이다. 이러한 문제점을 개선하기 위해서 중궤도 위성을 이용한 차세대 탐색구조 시스템 개발이 추진 중에 있으며 EU에서 2011년 FOC(Full Operation Capability)를 목표로 개발중인 갈릴레오 항법위성 프로젝트의 경우 SAR 중계기를 탑재하여 탐색구조 서비스를 제공할 계획에 있다. 갈릴레오 탐색구조(SAR/Galileo) 서비스는 수 m급의 위치정확도, 10분 이내의 조난신호 접수에서 구조까지 소요시간, 및 조난자에게 회신링크 서비스 제공 등 보다 향상된 탐색구조 성능을 제공하기 위해 개발 중에 있으므로, 갈릴레오 위성 서비스가 시작되면 탐색구조시스템 체계에 보다 신속하고 정확한 구조가 가능할 것으로 예상된다. 우리나라에서는 COSPAS-SARSAT 회원국으로 가입하여 현재 송도 해양경찰청 내에 LEOLUT와 MCC가 설치되어 운용되고 있다. 날로 더해가는 다양한 재난에 대한 인명구조를 신속하고 효과적으로 대처하기 위해 차세대 갈릴레오 탐색구조 지상국 도입이 절실하다고 할 수 있다. 따라서, 탐색구조 단말기를 포함한 지상국 인프라의 구축 등 갈릴레오 탐색구조 지상시스템 개발의 참여 방안에 관한 연구는 매우 시기적절하고 중요한 연구이다. 본 논문은 갈릴레오 사업에 참여하여 SAR/Galileo 개발을 주관하고 있는 중국의 사례를 분석함으로 우리나라가 차세대 갈릴레오 탐색구조 지상시스템 개발에 참여하기 위해서 필요한 참여방법 및 절차 등을 도출하고, 참여 가능한 개발범위, 참여전략 및 추진체계에 대해서 제안한다.법의 성능을 평가를 위하여 원본 여권에서 얼굴 부분을 위조한 여권과 기울어진 여권 영상을 대상으로 실험한 결과, 제안된 방법이 여권의 코드 인식 및 얼굴 인증에 있어서 우수한 성능이 있음을 확인하였다.진행하고 있다.태도와 유아의 창의성간에는 상관이 없는 것으로 나타났고, 일반 유아의 아버지 양육태도와 유아의 창의성간의 상관에서는 아버지 양육태도의 성취-비성취 요인에서와 창의성제목의 추상성요인에서 상관이 있는 것으로 나타났다. 따라서 창의성이 높은 아동의 아버지의 양육태도는 일반 유아의 아버지와 보다 더 애정적이며 자율성이 높지만 창의성이 높은 아동의 집단내에서 창의성에 특별한 영향을 더 미치는 아버지의 양육방식은 발견되지 않았다. 반면 일반 유아의 경우 아버지의 성취지향성이 낮을 때 자녀의 창의성을 향상시킬 수 있는 것으로 나타났다. 이상에서 자녀의 창의성을 향상시키는 중요한 양육차원은 애정성이나 비성취지향성으로 나타나고 있어 정서적인 측면의 지원인 것으로 밝혀졌다.징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타 자료를 데이터베이스화했으며 이를 통해 학생들이 원하는 실시간 자료를 검색하여 찾을 수 있고 홈페이지를 방분했을 때 이해하기 어려운 그래프나 각 홈페이지가 제공하는 자료들에 대한 처리 방법을 도움말로 제공받을 수 있게 했다. 실시간 자료들을 이용한 학습은 학생들의 학습 의욕과 탐구 능력을 향상시켰으며 컴퓨터 활용 능력과 외국어 자료 활용 능력을 향상 시키는데도 도움을 주었다.지역산업 발전을 위한 기술역량이 강화될 것이다.정 ${\rightarrow}$ 분배 ${\rightarrow}$ 최대다수의 최대행복이다.는 역할을 한다. 따라

  • Sex steroids are generally considered as natural sex inducers in fish, and aromatase (cytochrome P450 aromatase) that catalyzes androgens into estrogens in the steroidogenic pathway is also known to be involved in sex differentiation. The timing of aromatase action is, thus, of central importance in the study of fish sex differentiation. We treated sexually undifferentiated tilapia (Oreochromis niloticus) larvae with $Fadrozole^{TM}$, a non-steroidal aromatase inhibitor (AI), by immersing the fish in a solution containing AI during the sex differentiation period to narrow down the critical period of aromatase action. Fish were treated once at 11 or 13 days post fertilization (dpf), or twice at 11 and 13 dpf. The concentrations of AI at each time of the treatment were 0 mg/L (control), 50 mg/L or 100 mg/L. Survival rate was not statistically associated with AI immersion treatment (p>0.25). However, sex ratio was significantly altered by the treatment, with higher concentration and double immersion being more effective in masculinizing genetic females (p<0.05). These results suggest that aromatase action for sex differentiation in this fish species would begin at least from 11 dpf which is much earlier than previously expected, and that only 3 hours of brief immersion in AI solution is powerful enough to alter genetically programed sex.

  • This study used a quasi-experimental method to investigate if both travel involvement and the degree of recall of a traumatic event affect subjective well-being. For this, independent variables such as positive affect, negative affect, and life satisfaction were established. Four waves of data collection were performed with two to three weeks intervals, then the collected longitudinal data were analysed by repeated measure ANOVA. The study results indicated that travel involvement increases positive affect and life satisfaction, with the effect lasting four weeks or more, which means that travel is an effective tool to boost subjective well-being. Respondents who thought about a traumatic event more frequently had a much higher negative affect following the disaster, and such increased negative affect was maintained over seven weeks or longer. Therefore, this study finds that negative events produce larger, more consistent, or more lasting effects than positive events. As well as travel participation, visiting an urban park is a pleasurable experience. Therefore, the study also finds that urban parks could be utilized for increasing and maintaining subjective well-being in the middle and long term as well as lessening personal stress.
