The objective of this research was to develop a relational database management system(RDBMS) to collect, manage and analyze data on agricultural non-point source(NPS) pollution. The system consists of the relational database for agricultural NPS data and data process modules. The data process modules were composed of four sub-modules for data input, management, analysis, and output. The data collected from the watershed of the upper Cheongmi stream and Geunsam-Ri were used in this study. The database was constructed using Apache Derby with meteorological, hydrological, water quality, and soil characteristics. Agricultural NPS-Data Management System(ANPS-DMS) was developed using Oracle Java. The system developed in this study can deal with a variety of agricultural NPS data and is expected to provide an appropriate data management tool for agricultural NPS studies.

웹2.0 환경의 발달과 함께 XML 데이터의 사용도 증가하였는데, 특히 블로그나 뉴스 피드의 정보 전달을 위한 RSS나 ATOM 포맷의 기반 기술로 사용되면서 그 장점과 가치를 인정받고 있다. XML 데이터의 인덱싱을 위한 여러 기법들 중 빠른 검색성능을 보인 비트맵 클러스터링은 관계형 DBMS를 기반으로 메모리에 인덱스를 유지하는 기법이다. 기존의 비트맵 클러스터링 기법을 이용하여 XML 데이터를 인덱싱할 때 너무 많은 클러스터가 생성되어 오히려 검색 효율과 결과의 품질이 저하되는 문제점이 있었다. 본 논문에서는 이 문제점을 해결하기 위해 사용자가 제시하는 k개의 클러스터를 생성하는 k-비트맵 클러스터링 기법과 대표비트를 생성할 때 배제된 단어를 검색하기 위한 역인덱스를 함께 유지하는 방법을 제안한다. 성능평가를 수행한 결과 제안하는 기법은 생성되는 클러스터의 수를 임의로 설정할 수 있을 뿐만 아니라 단일 단어 검색에서 높은 재현율을 보였고, 2개의 인덱스를 함께 유지할 때에는 질의에 대해 모든 관련된 문서의 반환을 보장하였다.

This study is aiming to present administrative guiding principles and suggestions to find methods to improve and bring up the ethic code of business of aligned companies, by examining how the factors of union of relations depending on characteristics of business, influence outcome of aligned companies, under the circumstances where efforts to improve outcome of aligned company through dealing relation between a mother company and the aligned company. First of all, as a result of analyzing how the characteristics of business have an influence on the relational union, it is shown that characteristics of product, peculiar assets of business, and opportunistic dispositive factors have an influence on reliance and devotion which are relation uniting factors. Under the actively changing circumstances, in order that the manufacturing companies can have a competitiveness, it can be said that shortening of developing period of new products, reduction of manufacturing and operating cost, and improvement of quality and productivity are compulsory factors. This can be achieved by having close relations with aligned companies which provide with parts and materials. As a result of analyzing how relational uniting factors like reliance and devotion influence business outcome of aligned companies. it is found that both reliance and devotion influence administrative outcome, although it is shown that they do not influence economic results such as reduction of cost. Therefore, it can be said that the mutual cooperation is required to increase mutual reliance and devotion, since increase of reliance and devotion are compulsory factors for efficient development of companies where a mother company and the aligned companies coexist, since they ease uncertainty in dealings, and devise administrative outcome.

Purpose: The aim of the study was to explore nurses' experience of person-centered relational care in the context of critical care. Methods: Key interview questions were developed based on the human-to-human relationship model suggested by Travelbee. Data were collected through indepth interviews with a purposive sample of 11 nurses having more than 2 years of working experience in intensive care units. An interpretative phenomenological analysis was conducted to analyze the data. Results: Four super-ordinate and nine sub-ordinate themes were identified. Emerged super-ordinate themes were as follows: (1) encountering a live person via patient monitoring systems; (2) deep empathic connection; (3) humanistic and compassionate care, and (4) accompanying the journey to the end. Study findings revealed that nurses in intensive care units experienced 'balancing emotions' and 'authenticity' in caring when entering human-to-human relationships with dying patients. The phenomenon of person-centered relational care in intensive care units was found to subsume intrinsic attributes of empathy, compassion, and trust, similar to the central concepts of Travelbee's theory. Conclusion: The interpretative findings in this study provide deeper understanding of Travelbee's human-to-human relationship model. The technological environment in intensive care units did not hinder experienced nurses from forming human-to-human relationships. These themes need to be emphasized in critical care nursing education as well as in nursing management. The results of this study will contribute to understanding nurse-patient caring relationships in depth, and help improve the quality of nursing care in intensive care units.

Nowadays an information exchange on XML such as B2B electronic commerce is spreading. Therefore the systematic and stable management mechanism for storing the exchanged Information is needed. For this goal there are many research activities for connection between XML application and relational database. But because XML data have hierarchical structures and relational database can store only flat-structured data, we need to store XML data in object-oriented database that support hierarchical structure. Accordingly the modeling methodology for storing XML data in object-oriented database is needed. In order to build good quality application systems, modeling is an important first step. In 1997, the OMG adopted the UML as its standard modeling language. Since industry has warmly embraced UML, its popularity should become more important in the future. So a design methodology based on UML is need to develop efficiently XML applications. In this paper, we propose a unified design methodology for XML applications based on object- oriented database using UML. To this goal, first we introduce a XML modeling methodology to design W3C XML schema using UML and second we propose data modeling methodology for object-oriented database schema to store efficiently XML data in object-oriented databases.

Recently, the engine calibration technique has been much more complicated than that of the past engine case in order to satisfy the strict emission regulations. The current calibration method for the diesel engine which has an increasing market is both costly and time-consuming. New engine calibration method is required to develop for high-quality diesel engines with low cost and release it at the appropriate time. This study provides the optimal calibrating technique for complex engine systems using statistical modeling and numerical optimization. Firstly, it design a test plan based on Design of Experiments, a V-optimality methodology which is suitable looking for set-points, and determine the shape of test engine response. Secondly, it uses functions to make linear regression model for data analysis and optimization to fit the models of engines behavior. Finally, it generates the optimal calibrations obtained directly from empirical engine models using Grey Relational Analysis and compares the calibrations with data. This method can develop a process for systematically identifying the optimal balance of engine emissions.

사회네트워킹 사이트(SNS)의 성공은 많은 요소에 의존한다. SNS의 지속적인 이용은 그 중 하나이다. 특히, 이용자가 손쉽게 다른 서비스로 전환할 수 있는 웹 환경에서는 기존 이용자들을 관리하는데 많은 시간과 노력이 소요된다. 이런 점에서, SNS의 지속적인 이용 없이는 SNS를 기반으로 하는 서비스는 가치창출에 실패하게 될 것이다. 본 연구는 SNS 이용자 지속의도에 영향을 미치는 요인들을 발굴하는데 목적이 있다. 초기단계로서, 관련 문헌연구를 통해서 여섯 개의 영향요인을 발굴하였다. 이들은 평판도, 관계적 가치, 지식품질, 적합성, 개인화, 만족도 이다. 미국 대학 및 대학원생을 대상으로 웹 설문조사를 수행하여 총 325개의 활용 가능한 데이터를 수집하였다. 신뢰도 검사와 두 차례의 탐험적 요인분석을 수행하여 다섯 개의 최종 영향요인을 발굴하였다. 영향요인들과 지속의도의 관계를 밝히기 위해서 회귀분석을 또한 수행하였다. 만족도가 가장 유효한 요인이었으며 지식품질과 관계적 가치도 유효한 요인이었다. 그러나 평판도와 개인화는 지속의도에 유효한 영향을 미치지 않았다. 대신에 이들의 만족도에 대한 영향은 유효하였다.
