The purpose of this study is to develop the argumentation program to build scientific concepts on natural selection for science-gifted elementary students and to know how to implement this program. For this study, nine key concepts about natural selection such as the overproduction of offspring, limited resources, population stability, competition, variation, heredity of variation, differential survival, change of the population and speciation were selected through the literature study. The programs were developed by learning cycle instructional model. Argument writings and discourses have been collected, analyzed and compared before and after the program. Two questionnaires to compare pre and post concept change consist of multiple choice questionnaire and open-ended response question were developed and applied to 19 science-gifted elementary students. Sufficiency of the explanation and conceptual quality of the explanation were used to assess the quality of their arguments before and after the program. Discourse and visual models collected from the highest and lowest group about score improvement were compared. The scores of the gifted statistically improved significantly in multiple choice questionnaire. Students' alternative conceptions about natural selection at the beginning of the program decreased and changed scientifically after the program. Visual models drawn by the students supported the results as well. This study asserts that elementary science-gifted students are able to explain evolutionary perspectives about organism change and use the key concepts of natural selection. The study means that evolutionary perspective is possible to be reflected in elementary science curriculum for the gifted.

Present study confirmed the influential relationships among menus choices, IMC activities, customer satisfaction and revisit intention as perceived by Italian restaurant consumers to establish the marketing strategy. The results are as follows: The menu choice traits of the Italian restaurants have proved that menu quality, menu composition, and physical offer have significant influences on the customer satisfaction. In addition, all the factors of menu choice traits except physical offer have significant effect on the customer's revisit intention. Furthermore, the IMC activities of the Italian restaurants have been proved that the advertisement and the public relations have significant influence on the customer satisfaction and revisit intention, but there was no signigicant impact with personal selling. Last, the customer satisfaction has been identified as a critical antecedent of revisit intention in this study.

1994년도부터 새로 실시된 대학입시 본고사를 위한 고려대학교 출제관리위원회의 활동을 통계적 측면에서 보고한다. 특히 모의고사의 문항분석과 선택과목 등화(표준점수제)에 관한 통계적 방법론을 중점적으로 다루고 그 성과에 대하여 논의한다. 이 실증적 사례 연구가 새로 대학입시 본고사를 실시하는 타 대학에 실질적 도움이 되기를 희망한다.

The concept of evolution is one of the most important concepts in the learning biology. However lots of students have difficulties in understanding its mechanism because their preexisted alternative concepts interrupt in gaining the correct idea of evolution. Students usually have the Larmarkian or teleological ideas of evolution. The purpose of this study is to investigate the effectiveness of an activity-centered instruction on the learner's conceptual change from misconception into the scientific concept, Darwinian one, and achievement. For the study, 162 students were sampled from a high school: 81 students for the activity-centered instruction and 81 students for traditional instruction. The result is as follows; 1) The activity-centered instruction is more effective than the traditional one in understanding the concept of Darwinian natural selection(p<.05) and in changing the students' various misconceptions of evolution into Darwinian one. 2) The activity-centered instruction concerning natural selection is more effective in their achievement(p<.01). 3) However, after both of the instructions, some students still kept the Lamarkian thoughts.

This study aims to investigate how labour time pressure is associated with leisure selection and managing leisure hours, especially focusing on health related behavior issues. I have employed Time Diary data of 9,891 Korean respondents who were married and living in the cities and metropolitan area (female 51.8%, age range 20-69, average age=45.7). Leisure activities, as dependent variable, which were introduced in time diary data and the amount of time spent for such leisure were estimated. Results show that in time pressing situations(having long labour hours), leisure activities, and the hours spent for leisure tend to suffer. Especially, solitary leisure, like exercise or walking was very likely to sacrifice under time pressure. Moreover, in terms of sports or exercise, results suggest that not only time resource but also social and economic resources seemed to required for actually initiating the activity. Therefore, simply having more time (less tiome for work) may not be enough for promoting exercise for this population. Strategies and social policies that are aiming for promoting healthy behavior needs more closer look on leisure situation and people's desire for optimizing their time.

The purpose of this study is to explore four-year old children's peer culture. During free choice play time, various activities and interaction patterns were observed and analyzed to understand the characteristics of peer culture. The results of this study showed two main peer culture patterns. First of all, peaceful peer culture in which children maintained close relationships based on mutual respect were found. Also conflictive peer culture in which children had negative relationships with other children, such as vertical, discriminative and neglected relationships were observed.

The purpose of this study was to find out the feature of children's play according to a player number restriction rule in the free choice activities. And it is expected that the result of this study will contribute to improving the management of free choice activities. The participants of this study were a homeroom teacher, professor as a co-researcher and 25 4-year-old children of a private kindergarten. The data were collected by observation, children interview and reflective journal of the teacher from July to October in 2014. The results indicated that the children were stressed out with using name cards for presenting center selection, showed overcompetitive behaviors, and frequently violated the rules. The researchers found that the restriction rule had some dysfunctions, which were interferences of moral development, social-emotional development, self-regulation development, preventing safety-accident and free choice behavior. The researcher as a teacher abandoned the player number restriction rule, and observed the children's play. As a result, children's self-regulation abilities on physical space, play and conflicts improved and the teacher changed her strategy when managing free choice activities. Based on the results, the needs of various restriction rules and appropriate methods for applying the rules in free choice activities were further discussed.

최근의 기업 환경은 글로벌화의 진전과 산업문명의 발달, 정보 습득이 용이 등으로 급속도로 소비자 중심의 시장으로 전환되었으며 이로 인해 기업 간의 경쟁은 급격히 가속되고 있는 상황이다. 이러한 상황 아래 고객에게 제공하는 가치가 유사한 기업들은 자사의 제품과 서비스를 차별화하여 기업의 경쟁력을 강화하기 위해 다양한 방법을 시도하고 있다. 이 다양한 방법들 중 대표적인 한 가지가 자사의 브랜드를 강력하게 만들어 관리하는 것이다. 현대의 소비자들은 단지 제품이나 서비스의 품질, 또는 가격들 중 하나로 제품을 선택하는 것이 아니라 종합적 경험으로 자신에게 각인되어 있는 브랜드의 선택을 통하여 제품이나 서비스를 구매하게 된다. 또 하나의 대표적인 방법이 경영혁신 활동이다. 기업은 기존의 업무 방법을 재현해서만은 지속적인 경쟁력을 유지할 수 없다. 변화하는 기업 환경에 맞춰 기업의 가장 중요한 부분을 본질적으로 변화 시켜야만 기업의 경쟁력을 지속적으로 유지, 향상 시킬 수 있다. 이에 본 연구에서는 기존에 연구된 문헌자료를 토대로 이론적 배경을 고찰하고 기업들의 경영혁신 추진 실태 조사와 K기관의 NBCI모델 통하여 산출된 브랜드 경쟁력 지수간의 상관관계를 분석함으로써 경영혁신 활동이 기업의 브랜드 자산 가치에 어떤 영향을 미치고 있는지 살펴보고자 한다.

Current discussions on productive aging are going towards the direction to sustain a social productivity and lessen a social burden, and this becomes distinct as it gives a strong value to the activity and independence of older people. This study highlights complex situations of productive activities in the group of older people by analyzing the survey of Among the productive activities of older people, two areas of activities - paid labor and social support - were interpreted differently according to their economic stability, spontaneity and family relations. This difference becomes more remarkable in the analysis on life satisfaction of older people. In paid work, which is the most common productive activity, there was a big difference in life satisfaction between those who work spontaneously and those who work inevitably to make a living. And in the comparison of life satisfaction for those who participate in homemaking and care working according to their economic situations and family relations, those who were unsatisfied with family relations showed lower life satisfaction.
