BLAST (Basic Local Alignment Search Tool) is a best well-known tool in a bioinformatics area. BLAST quickly compares input sequences with annotated huge sequence databases and predicts their functions. It helps biologists to make it easy to annotate newly found sequences with reduced experimental time, scope, and cost. However, as the amount of sequences is increasing remarkably with the advance of sequencing machines, performance of BLAST has been a critical issue and tried to solve it with several alternatives. In this paper, we propose a new PC-Based Cluster system (E-Cluster), a new physical data design methodology (logical partitioning technique) and a query routing technique (intra-query routing). To verify our system, we measure response time, speedup, and efficiency for various sizes of sequences in NR (Non-Redundancy) database. Experimental result shows that proposed system has better speedup and efficiency (maximum 600%) than those o( conventional approaches such as SMF machines, clusters, and grids.

디자이너에게 필요한 정보가 제품의 성격이 변함에 따라 변하면서 정보 수집의 흐름도 달라져가고 있다. 지금까 지의 디자인 정보 수집이 단순 설문조사에서 사용자의 사용상황을 관찰하는 보다 실질적인조사 혹은 컨텍스트 디 자인(Context Design: 사용환경을 고려한 디자인)으로 바뀌어 가고 있다. 그러나 기존의 조사분석방법들이 특정한 면(인지적 혹은 행위적)에 편중된 자료 수집에 초점이 맞추어져 있어서 다양한 정보의 수집과 이러한 정보의 통합 적 관리가 어려운 문제점을 가지고 있다. 정보의 수집과 통합적 관리의 어려움이 발생하게 되는 원인을 좀더 구체 적으로 살펴보면 첫째, 수잡되는 데이터의 문제이다. 데이터의 성격을 사용자인 개인의 조작행위에 중점을 두거나 또는 작업상황이나 사용자의 성격/선호도와 같은 부분에 중점을 두기 때문에 서로 상호작용하여 사용자 인터페이스에 큰 영향을 미치는 이 두 유형의 데이터에 관한 분석을 어렵게 하는 원인이 되고 있다. 둘째, 적당한 데이터 수집도구 (data logger)의 미비를 들 수 있다. 이것은 기존의 Data logger들은 정보를 문자나 숫자 또는 특수문자로서 정보를 추출하게 됨으로써 데이터를 뽑는 당시부터 정보가 추출자로인하여 1차적으로 가공이 된다는 점이다. 이것은 보다 실질적이고 분석단계에서 보다 면밀한 분석이 이루어 질 수 있는 중요한 데이터가 유출될 수도 있다는 것을 의미하는 것이다. 마지막으로 위에서 언급했던 두 유형의 데이터를 동시에 분석할 수 있는 방법의 부재와 실질적인 데이터를 분석하여 이를 디자인에 활용할 수 있는 정보로 가공할 수 있는 도구가 마련되어 있지 않다는 점이다. 디자인 작업은 종합적인 시각화 과정임에 비해 분석된 결과가 비시각적이며 위에서 언급했듯이 분절된 정보가 되기 쉽기 때문에 이를 디자인에 곧바로 적용시키기 어려운 점이 있다. 이에 본 연구는 기존의 바용성 평가를 위한 분석도구들이 갖는 문제 점들 해결하여 제품의 사용자 인터페이스 디자인 개발과정에서 활용할 수 있는 평가 분석도구를 개발하는 것을 목표로 한다. 이를 위해 첫째, 다양한 유형의 정보를 포함하는 비디오 정보를 선정하였따. 둘째, 데이터를 다양한 측면에서 추출할 수 있는 Data logger를 개발하였다. 셋째, 데이터를 시각적으로 정리하고 분석할 수 있는 도구를 제안한다. 마지막으로 인터페이스 디자인에서 여러 가지 디자인안을 도출해 내는 작업에 이용할 수 있는 종합화과정을 개발한다. 이러한 일련의 과정이 통합된 컴퓨터 시스템 안에서 이루어지도록 프로그램을 개발하여 정보의 유용성을 높일 수 있도록 한다.

Purpose: The purposes of this study were to identify the factors influencing service quality in nursing homes, and to develop an evaluation instrument for service quality. Methods: A three-phase process was employed for the study. 1) The important factors to evaluate the service quality in nursing homes were identified through a literature review, panel discussion and focus group interview, 2) the evaluation instrument was developed, and 3) validity and reliability of the study instrument were tested by factor analysis, Pearson correlation coefficient, Cronbach's ${\alpha}$ and Cohen's Kappa. Results: Factor analysis showed that the factors influencing service quality in nursing homes were healthcare, diet/assistance, therapy, environment and staff. To improve objectivity of the instrument, quantitative as well as qualitative evaluation approaches were adopted. The study instrument was developed with 30 items and showed acceptable construct validity. The criterion-related validity was a Pearson correlation coefficient of .85 in 151 care facilities. The internal consistency was Cronbach's ${\alpha}$=.95. Conclusion: The instrument has acceptable validity and a high degree of reliability. Staff in nursing homes can continuously improve and manage their services using the results of the evaluation instrument.

Purpose: Terminal cancer influences on patients as well as their family members. This research was performed to evaluate the quality of lift of primary family caregivers and to investigate the influencing factors. Methods: The results of survey were collected from 81 family caregivers who were taking care of hospitalized terminal cancer patients at an oncology department of university hospital in Daejeon from March 2005 to January 2006 with questionnaires. The questionnaires were consisted of the general characteristics of the subjects, and 36-items short-form Health Survey (SE-36) Korean version to evaluate the quality of life of family caregivers, the characteristics of patients and family caregivers' caring trait. Results: Family caregivers' mean (${\pm}SD$) SF-36 score was 47.9 (${\pm}20.7$). Influential factors on family caregivers' life quality were daily raring hours, economic burden, type of treatment; only supportive care, caring duration, sex, the numbers of ADLs (activity of daily livings) items that patients needed help in order by stepwised multiple logistic regression analysis (overall $R^2=0.639$, P=0.044). Conclusion: Daily raring hours and economic burden were two influential modifiable factors on family caregivers' quality of life. Therefore, social supportive systems are required to reduce family caregivers' daily caring hour and economic burden.

Over the past several decades, the assessment of quality of life (QoL) has increasingly played a prominent role in both clinical practice and research regardless of the medical field. Palliative care is defined as an approach that improves the QoL of patients and their families and optimizing their QoL is the primary goal of palliative care. However, it is difficult to compare related studies due to several obstacles such as discrepancies in definitions for palliative medicine, lack of consensus on the central domains and diverse instruments. In this paper, we examined the current status of and challenges in QoL studies and discussed possible solutions. We are convinced this review will be helpful for further palliative care studies.

The semantic web is taken as next generation standards of information exchange on the internet to overcome the limitations of the current web. To utilize the information on the semantic web, tools are required the functionality of query search and reasoning for the ontology. However, most of semantic web management tools cannot efficiently support the search for the complex query because they apply Triple-based storage structure about RDF metadata. We design the storage structure of the ontology in corresponding with the structure of ontology data and develop the search system(SMART-DLTriple) to support complex query search efficiently in this research. The performance of the system using new storage structure is evaluated to compare with the popular semantic web management systems. The proposed method and system make a contribution to enhancement of a practical ontology reasoning systems due to improved performance of the ontology search.

Purpose: A comprehensive evaluation item was developed to assess adolescent dietary habits and nutritional practices, considering food intake, eating behaviors, and food culture, such as social support and food environment. Methods: The 59 candidate items of the evaluation checklist were obtained based on the results of the eighth Korea National Health and Nutrition Examination Survey data, Korea Dietary Reference Intakes, dietary guidelines for adolescents, Youth Risk Behavior Survey data, national nutrition policies and dietary guidelines, and literature reviews. Four hundred and three middle and high school students residing in metropolitan areas participated in a survey using the 58-item checklist, which was selected through expert evaluation and content validity ratio analysis. The construct validity of the assessment tool for the quality of adolescent diets was assessed by exploratory factor analyses to determine if the checklist items were organized properly and whether the responses to each item were distributed adequately. Results: The Bartlett sphericity test was significant for each area (p <0.001), and the eigen values were greater than one. The Kaiser-Meyer-Olkin and cumulative proportions by areas were food intake (0.765 and 56.8%, respectively), eating behaviors (0.544 and 64.8%, respectively), and food environment (0.699 and 62.4%, respectively). Twenty-two checklists were determined for the final evaluation items for the adolescents' dietary habits and nutritional practices and were categorized into three distinct factors: food intake (10 items), eating behaviors (4 items), and food environment (8 items). Conclusion: The evaluation items for adolescent dietary habits and nutritional practices is a useful checklist for easily and quickly assessing the dietary qualities and reflecting Korean adolescents and their food environmental factors related to a sustainable diet.
