  • This study reviews and compares the selection procedures for science and technology topics to predict mid- and long-term trends in science and technology development in Korea, Japan, and the United Kingdom. It then identifies science and technology topics and future technologies for the third science and technology foresight of Korea. In Japan and the United Kingdom, non-technological topics that reflect socioeconomic needs are also select-ed along with technological ones. This study provides the following policy implications to enhance reliability and effectiveness of the third science and technology foresight of Korea. First, selection of science and technology topics should coincide with the national goal, taking into account development trends in science and technology and socioeconomic needs. Second, the current prediction methodologies such as "delphi" do not fully consider future uncertainties in science and technology development. A scenario method is, for example, needed to present coherent pictures of alternative futures. finally, the third technology foresight should select and include topics that reflect domestic conditions and global trend in technological progress. This study suggests 117 topics for the third science and technology foresight.foresight.

  • Purpose - There are numerous theories for retail trade area analysis which are designed to select candidate locations for new stores. In this study, comparative analysis on the characteristics from those of the theories are shown, and the explanation for the power in consumers' store-choice behaviors and their limitations are examined. Also, plans for improving commercial sphere analysis are explored. Research design, data, and methodology - This study is based on literature reviews with normative research methodology. Among many researches regarding the analysis on the location and commercial sphere for launching a new store, researches relying on statistics are excluded in this study since they belong to the marketing research area,. Results - In the Law of retail gravitation, Huff's model multinomial logit model and etc. are mutual complementary mathematical techniques for analyzing commercial spheres and each of them has its own characteristics. These theories rely on the same hypothesis in which consumers are all believed to be behaving rationally under a similar behavioral system. However, the trial in explaining or estimating behavior of choosing a store with only a select size of the population that is objectively estimated by some major properties has limits in its credibility. Conclusion - Research on consumer's spatial behaviors can be fully illustrative and explainable when it has both quantitative approaches such as 'law of retail gravitation', 'logit model' and etc., and qualitative approaches like consumer's 'cognitive structure', 'learning status', 'image formation', 'attitude' and etc.

  • Maintaining efficient energy consumption and elongating network lifetime are the key issues in wireless sensor networks. Existing routing protocols usually select the cluster heads based on the proximity to the sensor nodes. In this case the cluster heads can be placed farther to the base station, than the distance between the sensor nodes and the base station, which yields inefficient energy consumption. In this work we propose a novel algorithm that select the nodes in a cluster and the cluster heads based on the locations of related nodes. We verify that the proposed algorithm gives better performance in terms of network life time than existing solutions.

  • Character customization means a series of processes to build a characters. Mobile character customizing system is very scarce than Online RPG system qualitatively or quantitatively. In this paper, I will propose some effective elements about A DIY character system that must be suitable for the mobile environment system. The reasons why Select System is mainly used as the customizing system in RPG are as follows; First, the screen of a mobile device is small; Second, it is due to the space-time characteristics with which mobile games are played. In the middle of playing a game, a customizing system should be adopted in order for players not to feel bored. In addition, avatar's costumes should be continually updated.

  • The purpose of this study was to examine the awareness of racial features, racial in-group classification and preference by Korean children. The study participants comprised 89 children aged 3-5 years. The children performed photograph description and choice tasks. The major findings were as follows: First, older children were significantly more likely than younger children to use racial feature and less likely to use general physical feature to describe the stimuli. Second, children tended to select the South-Asian person speaking in Korean language as a Korean, rather than the Korean person speaking in English. Third, children tended to select the person of Korean appearance speaking in English as a playmate. The result revealed the developmental features of racial awareness. Furthermore the correspondence of language plays an important role on the children's in-group classification whereas the correspondence of appearance plays an important role on the children's preference.

  • This study was intended to develop food and nutrition cyberclass contents for nonmajor students at university. We investigated universities which offered food and nutrition related courses in 1998 by a telephone survey in order to select the most appropriate lecture contents for the nonmajor university students. We investigated to select the most needed lecture contents for the students, 15 questions on evaluation of cyberclasses which they took. The number of subjects were 140 students of ‘C’university who registered for nonmajor food and nutrition course in 1998. Among 140 students, 80 were cyberclass students and 60 were non cyberclass students. The results of the survey were as following : Fifty-five universities out of 62 had curriculums on food and nutrition in 1998 and 36,802 students attended the non major food and nutrition lectures. 84.9% of the respondents had their own computes and the main application mostly used was word processing. Additionally, 33.3% of them used on-line communications and 81.4% of them used internet. The most interesting subject of the respondents was ‘disease and nutrition management’. The male respondents were concerned more about ‘alcohol and health’, whereas the females were concerned about ‘obesity and weight control’.

  • The number of abnormal operation procedures (AOPs) for mitigating a plant abnormal status amounts to about one hundreds for the most of 1000MWe optimized power plant (OPR1000) and it is expected that the number of AOPs would be increased to cope with an abnormal status occurred newly. However, it is not well organized for operators to select a proper AOP from alarms occurred in main control room (MCR) during a plant abnormal status. It may be a burden to operators since the selection of AOP to respond an abnormal status is authorized by operators. When multiple alarms occur in MCR, it would take more time to respond them than a single alarm. To reduce the efforts, various MCR operation support systems have been developed. The purpose of this study was to develop a multi-alarm pattern card to select an appropriate AOP effectively when multiple alarms occurs in a single upper layout (UL) of MCR. It can be applied for an operation support tool as well as an education tool.
