The On-Line Analytical Processing (OLAP) tools access data from the data warehouse for complex data analysis, such as multidimensional data analysis, and decision support activities. Current research has lead to new developments in all aspects of data warehousing, however, there are still a number of problems that need to be solved for making data warehousing effective. View maintenance, one of them, is to maintain view in response to updates in source data. Keeping the view consistent with updates to the base relations, however, can be expensive, since it may involve querying external sources where the base relations reside. In order to reduce maintenance costs, it is possible to maintain the views using information that is strictly local to the data warehouse. This process is usually referred to as "self-maintenance of views". A number of algorithm have been proposed for self maintenance of views where they keep some additional information in data warehouse in the form of auxiliary views. But those algorithms did not consider a consistency of materialized views using view self-maintenance. The purpose of this paper is to research consistency problem when self-maintenance of views is implemented. The proposed "conveyor algorithm" will resolved a complete consistency of materialized view using self-maintenance with considering network delay. The rationale for conveyor algorithm and performance characteristics are described in detail.

화상회의 시스템 사용자 증가 및 기술 발전으로 인해, 화상회의 사용맥락과 화상회의 인터페이스 레이아웃이 다양해졌다. 사회불안은 화상회의 소통상황에도 영향을 주는데, 대면소통과 구별되는 요소인 비디오 피드백과 밀접한 관련성이 있는 것으로 나타났다. 비디오 피드백은 상대방에게 보이는 본인의 모습을 화상회의 시스템 인터페이스에 표시해주는 기능이다. 비디오 피드백은 업무 성과를 저해하고 피로감을 유발하는 것으로 알려졌으나, 화상회의 시스템에서 기본 기능으로 설정되어 있고 사용자들에게 보편적으로 선호된다. 본 연구는 과업지향정도, 비디오 피드백 화면크기, 사회불안이 비디오 피드백 선호도에 미치는 영향을 보기 위해 실시되었다. 연구는 온라인 설문으로 진행되었고, 설문 참가자는 화상회의 중 과업지향정도, 사회불안수준, 선호하는 비디오 피드백 화면크기, 비디오 피드백 기능 선호도를 평가하는 문항에 응답하였다. 연구 결과, 비디오 피드백 화면크기는 과업지향정도와 비디오 피드백 선호도를 매개하는 것으로 나타났다. 구체적으로 과업지향정도가 높을수록 작은 비디오 피드백 화면크기를 선호하였고, 이는 비디오 피드백 선호도 감소로 이어졌다. 한편, 사회불안수준에 따른 비디오 피드백 화면크기의 매개효과 차이는 유의미하지 않았다. 이러한 결과는 사용자와 화상회의 시스템의 상호작용에 대한 이해에 도움을 주어 화상회의 시스템 디자인에 활용될 수 있는 정보를 제공한다.

The purpose of this study is to apprehend college women's views on marriage in order to systematize the view theoretically, and to investigate the relationship between the self-actualization and their marriage perspective. Futhermore, it is my hope to provide some basic materials for making an desirable view on marriage. The measuring tools used for preparing this study are self-actualization test, which were designed originally by Shostrom and standardized to be suitable for Korean society by Kim Jae Ean and Lee Kwang Ja and a questionnaire about one's view on marriage. Statistical methods such as frequency, percentile, arithmetic mean, analysis of variances(X2 and F values)were used for data analysis. The results of this study are as follows; 1) It is revealed that more than half(59.7%) of the college women achieve normal or above normal degree of self-actualization. 2)It is revealed that most college women's attitude toward matrimony is positive and they have a large acquaintance with the opposite sex. Especially, they are eager to became employed after entering into matrimony. 3) It is revealed that the more satisfaction a college woman's mother feels about her own matrimony, the more positive attitude her daughter has toward marriage. some college women who do not want to have a child have a positive attitude toward divorce. This means that their matrimony depends upon their view of marriage. 4) It is revealed that the more self-actualization college women feel, the more negative attitude they have toward selecting their husband. 5)It is revealed that the less self-actualization college women feel, the more negative attitude they have toward having a large acquaintance with the opposite sex and they have a dependent attitude toward living with their parents 6) It is revealed that most college women want their husband to have higher academic career than hers regardless of her own self-actualization degree and they want have a job after entering into matrimony. It seems to be dispassionate reflection of contemporary thought.

The purpose of this paper is to compare and analyze the two different teaching methods of elementary mathematics in the traditional method and in the constructive view. To do so, the actual class in the constructive view has been made for about four months using a class of 45 students in the second grade of an elementary school. After the class was finished, we collected diverse data from the class, such as the responses from the children(self-evaluation, mathematics diary, observation by the investigator, daily report), class evaluation report by other teacher and so on. The results of this research are as follows: First, the traditional class reaches at the goal of learning in a unit time because the class is guided by the teacher but the class in the constructive view is a little flexible because it is contextual. Second, in the constructive process of mathematical knowledge we knew that small group activities or discussion without intervention of teacher was often ended in exhaustive argument without arriving at valid social consensus. Third, the attitude in mathematics was changed from the passive one to the self-regulated ones. Fourth, the class in the constructive view could extend not only the ability of mathematical communication but also the ability of self-directed learning of children. Fifth, it was a considerable change the role of teacher, that is, guide of instruction instead of unique specialist in the classroom. Sixth, finally, the evaluation was made after finishing a unit class in the traditional instruction but it was integrated in a class in a constructive view.

The purpose of this study is to investigate the relationship between self-esteem and the view of the afterlife of the elderly by focusing on mediating effects of positive satisfaction and death preparation. Therefore, this study emphasizes the importance of the rest of life and contributes as exploratory research toward strengthening the psychological and emotional well-being of the elderly. After using a structural equation model, we found that self-esteem influenced their view of the afterlife through mediating effects such as positive satisfaction and the level of death preparation. The results of this study will present not only in recovering from death anxiety through an understanding of the level of death preparation and, the view of the afterlife but also in the development of practical intervention materials, which can be useful in social work for the elderly. The elderly's view of the afterlife should be strengthened according to the educational programs on death preparation that deal with the existence of the afterlife and life after death. However, this study has the limitation that only people living in Seoul and Gyeonggi Province and not in the other areas of the country were considered in this research. Nevertheless, within its limitation, this study's findings are promising, as they contribute to our understanding of the view of life and death of the elderly; further, the study has academic meaning with respect to helping the elderly successfully carry out their life development tasks and significantly prepare for the rest of their life.

The Maa speaking Torobo people inhabiting the southern portion of the Mau Escarpment in Kenya approach both individual and community survival from a relational orientation focused on ethnic identity and responsibility. This social responsibility to the tribe is in stark contrast to Torobo relationships with other ethnic groups. The purpose of the research is twofold. First, the paper explores how folkloric language through a trickster image reflects important cultural and social ideals, understandings, and patterns of thought in Torobo world view. A second purpose is to offer ethnographic information to scholars and students' alike necessary for world view studies of eastern Africa specifically focused on the interplay between anthropomorphic tales and the social context in which these stories are utilized. The key research question for this analysis asks how the trickster image in Torobo folklore conceptualize the life experience. A Torobo folktale entitled, The Clever Hare, is the text chosen for analysis with the hare character as the protagonist. A second query explores the importance of the trickster image in understanding Torobo world view categories of Self and Other. The analysis contributes an ethnographic perspective for the world view categories of Self and Other as well as trickster folklore by examining the nature of Torobo-ness using the tale of the cunning hare as a research tool.

The present study aimed to examine the relationships between work-related support factors and attitude towards teleworking and explore the moderating effect of self-identity on that relationship. The present study collected data from 343 IT professionals in South Korea through a survey method and used hierarchical multiple regression analyses. In the results, first, the more supervisory or work-related supports participants perceive in teleworking platforms, the more favorable their attitudes towards teleworking. Second, the positive relationship between supervisory support and attitude towards teleworking is stronger for participants high rather than low in interdependent self-view. However, interdependent self-view was found to have no significance on the relationship between work colleague support and attitude towards teleworking. This study is the first to examine the integral model of work-related support factors of attitude towards teleworking and explore the moderating effect of self-identity in the teleworking process.

The purposes of this study were to examine the relationship among vanity, selfconsciousness, and brand consciousness. The subjects used for this study were three hundred and eighty-four female college students who live at Seoul and its suburb. For data analysis, descriptive statistics, Cronbach's alpha, Pearson's correlations, and t-test were used. All instruments which were used for this study showed over 0.85 for Cronbach's alpha values. As the results, first, there were significant correlation relationships among vanity, self-consciousness, and brand consciousness in female college students. Second, there were significant differences between high self-consciousness group and low selfconsciousness group on vanity and two vanity variables such as physical view vanity and physical concern vanity. High self-consciousness group had higher scores on total vanity as expected. Also high self-consciousness group had higher scores on physical view vanity and physical concern vanity than low self-consciousness group. Finally, there were significant differences between high self-consciousness group and low self- consciousness group on brand consciousness. That is, compared to low self-c onsciousness group, high self-consciousness group showed higher brand consciousness significantly. Based on these results of this study, fashion brand management marketing strategies such as consumer-brand relationship marketing would be provided to fashion marketers or fashion retailers.

Objective: The purpose of this study is to present a detailed view of the self-regulation of 5-year-old children based on parental attitudes and consistency. Methods: The research was conducted among 144 pairs of parents (288 people) of 5-year-old children residing in Seoul. Results: The resultsare as follows. First, with regards to self-regulation based on a child'sgenderand mother's parental attitudes, sub-factors such as parental attitudes and parental interaction were found to have significant effects on self-determination. Also,parental attitudes and parental interaction were found to have significant effects on the sub-factors of self-monitoring, such as self-evaluation and self-determination and the sub-factors of self-regulation, such as behavioral inhibition and emotionality. Second, the percentage of parents whose parental attitude was consistent at 58.3%, which is higher than the percentage of parents whose parenting attitude was inconsistent at 41.7%. The results of self-regulation were significantly higher when parental attitudes were consistent than when they were inconsistent. Conclusion/Implications: This research is significant in that it offered a concrete view of parental attitudes and consistency status that affect child's self-regulation.
