The purpose of this study was to investigate information source of the choice of select dental medical institution and the relationship between socioeconomic characteristics and information searching pattern. This study was conducted for residents adults and teens living in Gwangju and rural communities of Jellanam-do province including. The study shows that 61.0 % of the information of selecting dental medical institutes had been introduced by the acquaintance and the rest of the information(37.0%) had been gotten from the internet. The purpose of this study is to develop an information search method that can influence the choice of medical consumers in dental clinics, and to establish a new dental clinic management strategy based on this research. Plus, we want to develop an information search source that can have a convergence effect on the selection of medical consumers in dental medical institutions.

업무중심이었던 HCI가 인간의 모든 생활 접점에 존재하게 됨에 따라, 과업완료 중심의 HCI의 목표가 사용자 감성 만족, 심리적 만족 등으로 조정되고 있다. 이로 인해 다양한 사용자중심의 디자인 방법론들이 개발/제안되고 있다. 하지만 아직도 대다수의 사용자 중심 HCI관련 연구가 인간을 하나의 도구적 프로세스 관점으로 인식한 개인 특성연구에 치우쳐있다. 본 연구는 위에서 제기된 문제점을 해결하고자 인간의 타고난 성정에 대한 인간의 유형화 방법인 한국사상 사상체질을 제안함과 동시에 SNS상에서의 자기표현 전략에 대해 탐색적인 기초실험연구를 진행하였다. 이 연구는 향후 카카오톡에서의 사상체질에 따른 자기표현방식을 연구하기 위한 실험 모델을 제안하여, 이 두 연구의 비교를 통해 각 미디어가 지닌 특성과 개인적 특성에 따른 자기표현전략을 제안 할 수 있다.

The purpose of this study is to examine women's propensity to consume cosmetics and to investigate the effects of the consumption propensity on product selection attributes and information search behaviors. The purpose of this study is to propose practical implications for corporate management and to provide useful information for setting the marketing direction in the cosmetics industry by identifying differentiated marketing strategy for the cosmetics market. The results of the study are as follows. When the factors of each variable are extracted, the shopping propensity was derived from trend pursuit, pleasure pursuit, show-off pursuit, and economic benefit pursuit propensities, while product selection attributes were derived from brand factor, service factor, marketing factor, and quality factor. To examine the relationship between variables, three hypotheses were set based on previous studies. As a result of the verification the followings were found; first, the consumption propensity has a partial effect on the product selection attributes. Second, consumption propensity has a partial effect on information search behavior. Product selection attributes were found to have a partial effect on information search behavior.

유전자 알고리즘(Genetic Algorithms)은 우수형질이 계속 번식하고 열성형질은 도태하는 자연의 진화 메커니즘을 모방한 탐색 알고리즘으로 전형적인 조합 최적화 문제에 많이 적용되고 있다. 유전자 알고리즘의 성능을 향상시키기 위해 알고리즘 실행과정에 적용할 수많은 이론과 경험적인 유전자 조작 기법이 제시되고 있는데, 이러한 기법들은 대부분 우수형질을 확보함으로써 최적의 값을 효과적으로 탐색하기 위한 것이다. 그러나, 적절하지 못한 유전자 조작의 경우 탐색지점의 제한등으로 인한 Local Optimum에 빠질 위험이 있으므로, 유전자 조작에 대한 평가가 이루어져야 한다. 본 연구에서는 유전자 알고리즘의 유전자 조작기법중 적응도 비례전략을 개선한 유전자조작이 적절한 선택기법들로 유전자 알고리즘에 응용될수 있는지를 밝히기 위해, 냅색문제를 대상으로 세대수의 변화에 따른 탐색 결과를 평가하였다.

Due to the recent technological improvements, the environments of e-books and its contents have been changed and the users of e-books have drastically increased. This study aimed to propose a model on how children access and search e-books in this digital era. For this study, a potential model was proposed based on the analyses on various information-seeking behavior models. For analyzing children's access and search processes on e-books, 30 children in five public libraries or school media centers in Seoul and Kyoungi-do areas were recruited for the in-depth interviews. As a potential model on children's access and search on e-books was re-visited and revised based on the results, a cyclic model of children's access and search on e-books was proposed containing six factors.

This study is intends to analyze achievements of the Literacy-computer education for the illiterates and to develop more efficient implementation strategies. For this purpose, we collected data of the costomer's satisfaction Ievels and its achievements of this program and analyzed its achievements perception by institutes variables, educational method variables, and individual character variables. Based on this results, we suggest specific strategies of this program for better effectiveness of literacy-computer education for the illeterate.

Genetic Algorithms are optimization algorithm that mimics biological evolution to solve optimization problems. Genetic algorithms provide an alternative to traditional optimization techniques by using directed random searches to locate optimal solutions in complex fitness landscapes. Hybrid genetic algorithm that is combined with local search called learning can sustain the balance between exploration and exploitation. The genetic traits that each individual in the population learns through evolution are transferred back to the next generation, and when this learning is combined with genetic algorithm we can expect the improvement of the search speed. This paper proposes a genetic algorithm based Cellular Learning with accelerated learning capability for function optimization. Proposed Cellular Learning strategy is based on periodic and convergent behaviors in cellular automata, and on the theory of transmitting to offspring the knowledge and experience that organisms acquire in their lifetime. We compared the search efficiency of Cellular Learning strategy with those of Lamarckian and Baldwin Effect in hybrid genetic algorithm. We showed that the local improvement by cellular learning could enhance the global performance higher by evaluating their performance through the experiment of various test bed functions and also showed that proposed learning strategy could find out the better global optima than conventional method.
