  • Purpose: Guided by Newman's theory of health as expanding consciousness, this study was done to explore the health experience of adolescents having depression. Methods: The researcher engaged in six to eight in-depth interviews with six adolescents. To begin the dialog, the researcher asked each participant to recount the first important memory he/ she had. All the narrative and diagram sharing between the researcher and participants were summarized according to recognized patterns and later elaborated in following interviews based on Newman's praxis methodology. Results: The significant individual pattern of early health experience was during the binding stage. At the turning point, individual patterns for participants revealed a personal journey of self-discovery and then emergence of reflecting behaviors. After the turning point, the participants changed as they evolved from the initial period of disruption and disorganization to organization at a higher level. The results suggest that adolescents who are depressive find new ways of relating to friends, family, healthcare providers, and the community by expanding their consciousness. Conclusion: Newman's praxis methodology is a good way of helping and studying adolescents with depression because it emphasizes participant-nurse/researcher partnership and pattern recognition as nursing practice.

  • 점차 복잡화되고, 다양화되고 있는 고객들의 수요를 만족시키기 위해 많은 인터넷 회사에서는 고객관계관리를 통하여 마케팅 활동을 벌이고 있다. 단기간 판매실적을 극대화하기 보다는 고객서비스와 장기간의 고객만족도를 더 많이 강화하기 위해서는 마케팅 계량지표로서 고객생애가치를 활용하는 것이 바람직하다. 이러한 고객생애가치는 인터넷 비즈니스 분야에서 경쟁적인 힘을 증진시킬 수 있는 고객가치를 발견할 수 있는 핵심이며, 많은 인터넷 기업들이 고객생애가치에 관심을 가지고 있다. 본 논문에서는 회원 유형별로 인터넷 사이트의 회원 수명을 분석하기 위해 생명표 기법을 활용함으로써 여러 형태의 인터넷 회사에 다양한 생명표를 이용할 수 있는 기회를 마련하고자 한다.

  • 디자인 패턴의 사용은 시스템을 좀 더 유연하고, 이해하기 쉽고, 재사용 가능하게 만든다. 개발이 완료된 시스템이 명확하게 문서화가 되어 있으면, 시스템의 내부 구조를 이해하기 쉽고, 향후 유지 보수의 비용이 적게 든다. 하지만, 대부분 시스템의 경우 개발된 시스템의 문서화가 잘 되어 있지 않기 때문에, 시스템에 문제가 생겨 수정 하고자 하거나, 새로운 모듈을 추가하여 시스템의 기능을 확장하고자 할 때, 전체 소스코드를 분석하여 시스템을 이해해야 하는 어려움이 있다. 이러한 문제점을 해결하기 위해서 소스코드에서 자동적으로 디자인 패턴을 인식하여 문서화를 증진시킬 수 있다. 따라서 신뢰할 만한 디자인 패턴 인식 시스템이 중요하다. 지금까지 디자인 패턴 인식 방법은 시스템의 구조적인 특징만을 이용하여 패턴을 인식하여 왔다. 그래서 본 논문은 구조적인 특징뿐만 아니라 동적인 분석, 그리고 자동학습(machine learning)에 기반하여 소스코드로부터 디자인 패턴을 인식하는 방법을 제안하고자 한다. 그리고 전 작업에서 만든 자바로 쓰여진 에이전트 개발 툴을 대상으로 실시하여 인식한 디자인 패턴에 대한 평가를 하였다.

  • Data mining is the method to find useful information for large amounts of data in database. It is used to find hidden knowledge by massive data, unexpectedly pattern, relation to new rule. The methods of data mining are association rules, decision tree, clustering, neural network and so on. Association rule mining searches for interesting relationships among items in a riven large data set. Association rules are frequently used by retail stores to assist in marketing, advertising, floor placement, and inventory control. There are three primary quality measures for association rule, support and confidence and lift. We analyze Gyeongnam social indicator survey data using association rule technique for environmental information discovery. We can use to environmental preservation and environmental improvement by association rule outputs.

  • Customers' needs change every moment. Profitability of stores can't be increased anymore with an existing standardized chain store management. Accordingly, a personalized store management tool needs through prediction of customers' preference. In this study, we propose a recommending procedure using dynamic customers' preference by analyzing the transaction database. We utilize self-organizing map algorithm and association rule mining which are applied to cluster the chain stores and explore purchase sequence of customers. We demonstrate that the proposed methodology makes an effect on recommendation of products in the market which is characterized by a fast fashion and a short product life cycle.

  • Stall inception means the phenomena of rotating stall initiation. The initiation mechanism of rotating stall, the existence of stall precursor, the behavior of stall precursor, stall warning scheme and control scheme are the main interests in stall inception research. Compared to the studies on rotating stall which has long history, the stall inception has been studied for about recent 20 years. After the first discovery of stall precursor in about 20 years ago, many studies were reported on stall inception phenomena. The inception pattern of 'mode' and 'spike' were found, and some of its characteristics are known. And now the stall inception has become one of the fascinating fields in turbomachinery. The development stall control scheme which apply the reliable stall warning scheme will play a great role in future compressor and aeroengine. This paper reviews the results and analysis methods on stall inception studies.

  • Clustering for gene expression data without filtering out noise genes may be distorted or derived inappropriate inference. Identifying significant genes and deleting noise before major analysis is necessary fur meaningful discovery from genes expression pattern. We proposed a new method of finding significant genes using factor analysis which is done on transposed data matrix. We construct significance score that is sum of factor loadings for declared significant number of factor, and set threshold through replication. Our proposed method works well for simulated time-course data for finding significant genes even though variance level gets larger.

  • The genome sequencing project has generated and will continue to generate enormous amounts of sequence data including 5 eukaryotic and about 60 prokaryotic genomes. Given this ever-increasing amounts of sequence information, new strategies are necessary to efficiently pursue the next phase of the genome project-the elucidation of gene expression patterns and gene product function on a whole genome scale. In order to assign functional information to the genome sequence, DNA chip(or gene microarray) technology was developed to efficiently identify the differential expression pattern of independent biological samples. DNA chip provides a new tool for genome expression analysis that may revolutionize many aspects of biotechnology including new drug discovery and disease diagnostics.
