The purpose of this study was to identity the relationship among emotional expression, emotional support, and psychosocial well-being, to analyze the factor affect the psychosocial well-being and to provide the data-based for effective development of emotional education program. The subjects for this study were 553 undergraduate college nursing students. The period of data collection was from 16 to 30, June, 2001. The instruments used for this study were emotional expressiveness scale (EES), ambivalence over emotional expressiveness questionnaire (AEQ), affect intensity measure (AIM), social support scale (SSS), and psychosocial well-being index (PWI). Data were analyzed by use of Descriptive Statistics, ANOVA, t-test, Stepwise multiple regression, Pearson's correlation coefficient with SPSS WIN program. The Major results were as follows: 1. The average score of items for the AIM, EES, AEQ were moderate at 3.8, 3.7 and 3.4. The level of SSS was high at 7.2 and PWI was low at 52.1. 2. Significant correlation were found between the AIM, EES, and AEQ. The EES was positively correlated with the SSS and negatively correlated with the PWI. On the other hand, the AEQ was positively associated with the PWI and negatively associated with the SSS. There was significantly negative correlation between the SSS and PWI. 3. In demographic characteristics, significant difference was shown only in the EES. The EES was significantly different according to grade. The difference in the SSS and PWI between 3groups were significant at the EES and AEQ. 4. Results from hierarchical multiple regression analysis indicated that the EES, AEQ, and AIM had influence on the SSS. And perceived the AEQ and SSS together explained 18.7% of variance in the PWI. The results of study provide evidence about the roles of emotion in psychosocial well-being. As a result, this study suggests that later study would be required to identify factors affect the psychosocial well-being and to develop the emotional education program to enhance emotional expression.

The aim of this study is to investigate the effects of intermittent ladder-climbing exercise training on mitochondrial biogenesis and ER stress of the cardiac muscle in high fat diet-induced obese middle-aged rats. We induced obesity over 6 weeks of period in 40 male Sprague-Dawley rats around 50 weeks old, and were randomly divided into four experimental groups: chow, HFD, exercise+HFD, and exercise+chow. The exercising groups underwent high-intensity intermittent training using a ladder-climbing and weight exercise 3 days/week for a total of 8 weeks. High-fat diet and concurrent exercise resulted in no significant reduction in body weight but caused a significant reduction in visceral fat weight (p<0.05). Expression of $PPAR{\delta}$ increased in the exercise groups and was significantly increased in the high-fat diet+exercise group (p<0.05). Among the ER stress-related proteins, the expression levels of p-PERK and CHOP, related to cardiac muscle damage, were significantly higher in the cardiac muscle of the high-fat diet group (p<0.05), and were significantly reduced by intermittent ladder-climbing exercise training (p<0.05). Specifically, this reduction was greater when the rats underwent exercise after switching back to the chow diet with a reduced caloric intake. Collectively, these results suggest that the combination of intermittent ladder-climbing exercise training and a reduced caloric intake can decrease the levels of ER stress-related proteins that contribute to cardiac muscle damage in obesity and aging. However, additional validation is required to understand the effects of these changes on mitochondrial biogenesis during exercise.

Glucose regulated protein 78 (GRP78) is frequently highly expressed in tumor cells, contributing to the acquisition of several phenotypic cancer hallmarks. GRP78 expression is also positively correlated with tumor metastasis, and promotes hepatocellular carcinoma cell invasion via increasing cell motility, however, other mechanisms involving the prometastatic roles of GRP78 remain to be elucidated. Here we report that forced GRP78 expression promotes colon cancer cell migration and invasion through upregulating MMP-2, MMP-9 and especially uPA production. These effects of GRP78 are mediated by enhancing the activation of ${\beta}$-catenin signaling. Interestingly, we identify that GRP78 interacts with uPA both in the cells and in the culture medium, suggesting that GRP78 protein is likely to directly facilitate uPA secretion via protein-protein interaction. Taken together, our findings demonstrate for the first time that besides stimulation of cell motility, GRP78 can act by increasing proteases production to promote tumor cell invasion.

2007년도 개정교육과정에서 비례 개념은 이전 교육 과정보다 하향조정되어 5학년에 도입된다. 비례 개념이 더 빠른 학년에 도입된다면 학생들이 비례문제를 해결하는 방법은 더 다양하고 비형식적인 전략이 사용될 가능성이 논다. 또한, 학생들이 비례문제에서 보이는 오류의 유형도 다양할 것이다. 따라서, 비례 개념을 더 이른 나이부터 강화하여 지도할 때 학생들의 비형식적 지식과 형식적 접근 사이의 간극을 없애려면 학생들이 비례 문제를 해결할 때 보이는 전략과 오류에 대한 연구가 필요하다. 본 연구에서는 비례 추론에 대한 선행연구들을 검토하여 비례 문제 해결의 전략과 오류를 정리하였다.

The department of education developed editing data of fisheries and shipping high school subject in 1987. But as change to informational society, the new term and predicate were built on a textbook of fisheries and shipping that was not in the past. Terms came into being in this way, it was used indiscreetly by spending a different expression on a textbook. In this study based on currently subject of fisheries and shipping high school 36books, examined an elementary school junior high school and a definition related term in order to solve these problems. Specialist on each field selected term and the predicate which is objective and proper. Especially field of fisheries and shipping uses a japanese term as it is. So there are a lot of the terms that is hard for students. Using these terms yet, the term that meaning delivery is uncertain and hard expression is going to carry out role to convert to a clear and easy term through this study.

Folded structure is widely applied in various engineering fields. Many of the Japanese folding fans in the Edo era (1603-1868) have been successfully blended with the processing technology of "natural materials" that is the origin of Japan's "Monodzukuri" (craftsmanship) and its application "artistic originality". The charm of a fan lies in the diversity of stereoscopic expression not born in plane representation. For example, the effects of folds, the expression of the front and back sides flowing from the front to the back by double-sided description, and the two-layer effect of raising the backside from the surface using the permeability of Japanese paper, the calculated depiction are also seen. Moreover, by handling the fan, it also produced an illusion effect which skillfully calculated the change due to movement of the viewpoint. Students experience the natural materials such as Japanese paper, bamboo and starch paste, which are the materials of paint and fan at the time, and processing method, and know the difference with the current one. This study is to verify the effectiveness of engineering education which gains experience by making concrete fans and to understand deeply this traditional technology with the artistry of a Japanese fan at the same time. And we can learn from the characteristics of the fan to Japan's history and culture.

This study examined how emotion regulation strategies specifically function in the interpersonal conflict coping strategies of engineering students. For this purpose, a interpersonal conflict coping strategies and emotion regulation strategies scale was used for 548 engineering students. Multiple regression analysis was conducted. Among the emotion regulation strategies, the "return to body" strategy was related to understanding, validation, focusing, and the "stop action" strategy. In particular, the "stop action" strategy was closely related only to the "return to body" strategy. Among interpersonal conflict coping strategies, the dominating strategy used both positive emotion regulation strategies, such as high refocus on planning, and negative emotion regulation strategies, such as other-blame. Additionally, among negative conflict coping strategies, it was confirmed that both aggression and negative emotional expression, which seem to have similar attributes, share a common feature of having high difficulty in emotional clarity. However, in the case of negative emotional expression, it is characterized by a lack of putting into perspective and high other-blame. On the other hand, the agression strategy seemed to have different characteristics, such as high self-blame and low return to body. By investigating the relationship between interpersonal conflict coping strategies and specific emotion regulation strategies, this study provides implications for education and intervention on which specific emotion regulation strategies need to be cultivated for engineering students to improve their interpersonal conflict resolution capabilities.

본 연구는 떡잎의 발달 동안 지방의 유동 및 대사와 관련된 오이 유전자들의 발현을 조사하여 유전자의 활성을 비교하고자 하였으며, 글라이옥시좀과 미토콘드리아 사이의 탄소원(아세틸 단위)의 가능한 경로를 탐색하고자 하였다. 네 곳의 세포 내 소기관인 글라이옥시좀(퍼옥시좀), 미토콘드리아, 엽록체 및 세포질에서 작동하는 중요 대사경로의 10개 유전자들이 조사되었다. 나아가 암소에서 발아한 유식물체의 발아 초기 반응과 이후 3일간 빛을 주었을 때의 반응을 조사하였다. 역전사-중합효소연쇄반응(RT-PCR)에 따르면, 유식물체의 발달 동안에 저장지방의 유동과 관련된 Thio2, ICL 및 MS 유전자는 항상 유사한 유전자 발현 양상을 나타냈다. 오이의 발아 초기에 BOU 유전자와 함께 ICL 및 MS 유전자의 공조된 발현은 퍼옥시좀과 미톤콘드리아 사이에 아세틸 단위의 2차 통로의 존재 가능성에 대한 강한 증거이다. 앞서 보고된 연구에서 보여준 BOU 활성에서처럼 BOU 유전자는 빛 의존성으로 암소에서는 세포막의 미약한 발달로 인하여 활성이 저하됨을 암시한다. 나머지의 유전자들은 떡잎이 초록색으로 발달하고 노쇠화 할 때까지 떡잎의 전 발달 기간 동안에 활성을 나타냈다. 본 연구에서는 아세틸 단위의 운반에 대한 새로운 추가적 제안으로써 지방 저장 종자의 발아와 오이 떡잎의 발달과 관련된 유전자의 발현을 통해 처음으로 확인하였다.
