The purpose of this study was to compare the 5 OEs of Korean gifted elementary and middle school students and non-gifted, and to find out the gender differences and level of school differences to clarify the possibility of identification instrument of giftedness based on the 5 OEs as the affective factor of giftedness. Total subjects were 270 in this study. Among them, gifted group were 74, and non-gifted group were 196. Boys were 202, and girls were 168. Elementary students were 34, middle school students were 40 within the gifted group. OEQII (Kim, 2008) were modified and used for elementary students. The result of this study were as follows. First, the level of 5 OEs of gifted students was significantly higher than non-gifted students. Second, gender differences were found. Total OEs and sensory OE and emotional OE of girls were significantly higher than boys'. Third, there were significant interaction effects among gifted and non-gifted and gender factor in total OEs and psychomotor OE and sensory OE. Fourth, there was no significantly differences of 5 OEs between elementary and middle school gifted students, which may be interpreted that OEs were consistent affective factors of giftedness. OEs were discussed as the possibility of identification instrument of giftedness.

In covering the controversies surrounding the so-called cyber defamation laws, the Korean press offered competitive frames in terms of values (security vs. freedom of speech) and attributional patterns (episodic vs. thematic attribution). By attending to core values and attributional patterns as two essential components of news frames, this study explored the cognitive and affective processes of value and attributional framing and their effects on issue opinion. According to a 3-group online experiment, first, it was found that core values increased the perceived importance of relevant beliefs, which further affected individuals' attitudes toward the laws. The affective effects of core values were also found marginally significant. The value of security increased the intensity of anger toward deviant netizens (so-called defamatory repliers), and it further increased individuals' support for the laws. It was not substantiated, however, that individualistic attribution, than social attribution, would provoke stronger anger toward defamatory repliers. Instead, episodic frames appeared to be more effective in driving issue opinion as indicated by the value frame.

The primary objective of this paper investigates whether asymmetric volatility phenomenon is caused by differences of opinion among investors and analyses information availability has an effect on asymmetric volatility. The empirical test period covers recent 6 years from January 4, 2000 to December 29, 2005. Five portfolios have been formed according to information availability(volume and market value). For the purpose of this study, We use TGARCH model, TGARCH-M model and adjusted model which include trading volume as a proxy differences of opinion among investors. The results are summarized as follows ; First, adjusted model analysis shows that asymmetric volatility phenomenon is disappeared or asymmetric coefficient and ratio is decreased than basis model. Second, portfolio analysis shows that the higher volume and market value, the more prominent asymmetric volatility phenomenon. And adjusted model analysis shows the higher volume and market value, the more decrease asymmetric ratio. Over all, assertion that differences of opinion among investors has caused asymmetric volatility phenomenon is regarded as reasonable. And, We see that information availability have great effect on asymmetric volatility phenomenon. We think that theses results can also occur opinion adjustment of optimistic investors. Namely, asymmetric volatility phenomenon can occur difference of information authenticity.

Recently the first stage qf construction for Busan new port emerged over the sea surface at the north container terminal site. With this, there are lot of discussions and debates on increasing the water depth at the approaching channel and mooring basin from the existing 15m to 18m by dredging work in order to be able to serve 12,000TEU containership, and at the same time, correction to the reclamation plan of hinterland at the part of Undong Bay qf the new port site. Since the attack of typhoon 'Maemi' in 2003, it is expected that the design wave parameters for coastal and harbor structures in this area would be somewhat changed and so the extreme wave condition at each terminal and tranquility of berthing area does, and therefore, it is necessary to analyze the tranquility at each berth Hence in this study, we constructed a wave model for these conditions and performed simulation together with the circulation model simulation, compared with the field data collected The result showed the increase of the harbor response throughout the basin but not severe condition However, a certain location needs to be prepared for the rough sea condition when a severe typhoon hit the site.

Effects of conjugated linoleic acid (CLA), known as an effective anticarcinogen in several animal models, on the tilapia were investigated. The CLA was made from safflower oil by alkaline isomerization method. Isomers in CLA such as cis-9, trans-11 and trans-10, cis-12 occupied over $80\%$, and other isomers was below $20\%$. In experiment, 250 fishes (average weight is 32 g) were divided into 15 fishes per five treatment and triplicate group for 8 weeks: control, $1\%$ CLA, $2.5\%$ CLA, $5.0\%$ CLA, and $10\%$ CLA diets. Daily growth rate and feed coefficiency were measured every week. The most effective diet for the growth rate and feed coefficiency of tilapia was $1.0\%$ CLA diet group. Every two weeks, sampled and determined the contents of CLA in the muscle and liver, After 8 weeks, $1.0\%$ and $10.0\%$ of CLA fed group accumulated the CLA as 41.3 and 180.9 mg/g of fat in their muscle respectively, Also, n-9 and n-3 fatty acid (FA) compositions were almost not changed in the muscle and liver. But n-6 fatty acid was changed according to the contents of fed CLA. The $1.0\%$ CLA fed group was shown the highest contents of n-6 FA and the $10.0\%$ CLA group was shown the lowest contents of n-6 FA.

KVN simulation, which is focused on evaluating the impacts of KVN to geodetic VLBI network, was performed. The KVN is under construction with three radio telescopes VLBI system for radio astronomy and space geodesy. To distinguish the impacts of KVN on global and local scale networks, we designed two different sizes of VLBI networks, namely, KVN-Asia and KVN-Pacific. While the former consisted of Far East Asia region VLBI stations, the latter consisted of pacific region VLBT stations. The primary purpose of our simulation is quantitative evaluation of KVN impacts before and after the participation of KVN in the previous two virtual networks. We selected two different sets of parameters to be estimated in the simulation as indices of evaluating estimation precision: station coordinates and EOPs. The station coordinates are evaluating index for KVN-Asia and the EOPs are another evaluating index for KVN-Pacific. From the simulation results of comparisons between evaluating indexes, 50% and 20% of maximum improvements for KVN-Asia and KVN-Pacific were anticipated respectively. We expect that the space geodetic use of KVN will be focused on the several promising research fields which are proposed through the simulation results.

WSN has been utilized in various directions from basic infrastructure of environment composition to business models including corporate inventory, production and distribution management. However, as energy organizations' private information, which should be protected safely, has been integrated with ICT such as WSN to be informatization, it is placed at potential risk of leaking out with ease. Accordingly, it is time to need secure sensor node deployment strategies for stable enterprise business. Establishment of fragmentary security enhancement strategies without considering energy organizations' security status has a great effect on energy organizations' business sustainability in the event of a security accident. However, most of the existing security level evaluation models for diagnosing energy organizations' security use technology-centered measurement methods, and there are very insufficient studies on managerial and environmental factors. Therefore, this study would like to diagnose energy organizations' security and to look into how to accordingly establish strategies for planning secure sensor node deployment strategies.

Our country is defenseless against the aging population in society that is suddenly and rapidly increasing. This is expressed as the aging shock and aged society earthquake, warning us of the crisis in the future society. Senior citizens of Korea are a group that does not receive proper education due to various social factors, and it is a group that requires lifelong education more than any other group, and therefore, senior citizens have become a priority target for lifelong education. Thus, the need for lifelong education for seniors can be said to be in establishing a new senior citizen image so that they may live a fuller retirement by improving their abilities to appropriately adapt to the rapidly changing modern society due to the digital times. Furthermore, with the enhanced cultural level and personal desire for a fuller life in the modern society, the necessity for leisure activities has been emphasized. Instead of simply relieving stress through leisure activities, it aims at being provided with educational opportunities through leisure activities. Therefore, senior leisure activity education should be an important method for establishing the senior citizen identity of a self-oriented senior, productive senior, volunteering senior, informed senior, and a well-rounded senior, which are all the image of senior citizens in the 21st century. In addition, a specialized leisure activity program that systematically provides education for leisure activities should be performed from the perspective of lifelong education. Hence, the significance of senior citizen leisure activities as lifelong education is in improving health, enhancing sociability and realizing one's self, while improving the quality of life for senior citizens. It will be greatly meaningful for establishing the new senior citizen image in which they independently live their own lives, while not being dependent on others, as required in the 21st century.

The study aims to suggest the direction of improvement in presenting the exhibition space by examining the current status quo of children's science exhibitions in order to enhance the educational effectiveness Children's Science Museum. For this purpose, the children's science museum exhibition and exhibition space were categorized into three themes largely according to the exhibition contents, and an analysis framework was developed to analyze exhibition media and exhibition space. For the research subjects, we selected 7 exhibition halls targeted at children in Korea, collected data via video-taping, and analyzed based on the framework of analysis. When analyzing the display situation in which the exhibits have the contents of 'body', 'peripheral things', and 'natural phenomena', we found that the exhibits are composed of too difficult contents to understand, which do not fit the children's developmental level, and the major media used are observational and explaining media. Additionally, concerning the exhibition space, there is a tendency to rely on the installation elements and color effect. It is also difficult to deduce the contents of the exhibits and the entire story. We suggest that the entire exhibition planning be carefully made from the beginning to improve the current status and enhance the educational effectiveness of the Children's Science Museum with the help of experts.
