Clinically, the fit of fixed prosthesis is an essential element for successful restoration. The fit of prosthesis is largely classified into marginal fit and internal fit, and various methods to assess these have been introduced including microscopic margin measurement, cross-sectional measurement, silicone replica technique, 3-dimensional scanning data superposition, weight technique and micro CT scanning. Thus, this study is aimed at proposing a more convenient and accurate measurement method of fits in a digital environment by comparatively analyzing the advantages and disadvantages of each known method based on existing literature.

Interest in conformance and the issues related to conformance and interoperability testing in ebXML products are rapidly gaining momentum among standards developers, implementers, and users. The goal is to obtain implementations of the standard that correctly perform the functionality specified in the standard. Conformance testing helps to achieve correct implementation. In this paper, we design and implement the CPP(Collaboration Protocol Profile)/CPA(Collaboration Protocol Agreement) and registry for ebXML conformance and interoperability testing tools that observe the standard specification in conformity with ebXML Message Service v2.0, ebXML Registry Service v2.0 and ebXML CPP/A v2.0.

To achieve this study, this study divide career orientations of AIS user into technology and management and group job characteristics into variety and autonomy and is to verify an effect of two factors on system performance (AIS satisfaction and use). The results of this study are as follows. First, there is a positive effect of the relevance between technology orientation and autonomy on AIS satisfaction. Second, there is a positive effect of the relevance between management orientation and job variety on AIS satisfaction. Third, there is a positive effect of the relevance between technology orientation and autonomy on AIS use, and finally, there is no positive effect of the relevance between management orientation and job variety on AIS use.

In this paper, how fast and accurate the companies provides exponentially increasing information to the users is the most important in the corporate competitiveness. The enhancement of the retrieval relevance became the important element in enhancing company competitiveness and it is required to provide the services that are beyond simple retrieval service for good quality search service. This paper proposes the effective scheme that enhances retrieval relevance by utilizing registered tag information. By proposed scheme, we can overcome the limitations of retrieval relevance that usual search engines provide. And we compare the proposed scheme with existing web retrieval service on retrieval relevance evaluation and related search keyword.

지구적 차원의 물부족 현상은 우리에게도 심각한 사회적 문제로 대두되고 있으며, 이에 대처하기 위한 방안의 하나로 지표수-지하수 연계이용이 거론되고 있다. 지표수와 지하수 연계이용은 유역의 지표 및 지하수자원을 수문학적 순환 사이클의 통합적 관점에서 파악하는 것으로부터 시작한다. 본 연구는 국내에서 지금까지 이렇다 할 사례가 없는 지표수-지하수 연계이용의 첫 단계로서 연계이용 가능지역을 선정하기 위한 체계적인 적지분석 방법론에 관한 것이다. 복잡한 의사결정 문제를 계층적으로 나누어 분석하는 기법(AHP)이 채택되었고, 분석에 필요한 의사결정인자가 도출되었다. 각 인자의 상대적 중요도가 정량화 된 후, 이를 바탕으로 특정 지역의 지표수-지하수 연계이용 적합도가 산정될 수 있다. 개발된 방법론을 국내 두 개 지역에 적용하여 그 적용성을 예시하였다 개발된 방법론에 의한 적합도 분석은 중앙정부나 지자체가 특정 지역의 연계이용 사업의 추진과 관련된 의사결정을 내릴 수 있도록 판단근거를 제공할 것이며, 지역 간 연계이용 우선순위를 평가하는데도 활용될 수 있을 것이다.

본 논문에서는 유전자 알고리즘과 피라미드(다단계 또는 다 해상도)를 결합한 새로운 영상분할 방법을 제안하다. 먼저, 영상을 피라미드의 해상도가 낮은 상위 단계로 분할하고 좋은 적합도를 가진 염색체의 개체군을 얻는다. 둘째, 해상도를 높인 다음 단계의 입력으로 앞 단계에서 얻은 염색체들을 사용하며, 더욱 세분화된 분할이 이루어지도록 염색체를 진화시키다. 유전자 알고리즘의 적합함수는 각 영역의 규질성과 peakiness를 이용하여 정의하였다. 교차는 교차점을 중심으로 영상을 2분하여 서로 교환하는 1점 교환법을 사용하였으며, 돌연변이는 병합과 분할이 이루어지도록 설계하였다. 본 논문은 저 해상도에서 가능성(적합성)이 큰 유전자를 신속히 구한 훙 단계적으로고 해상도에서 적합한 유전자로 진화시켜 나가는 방법으로 처음부터 최고 해상도에 유전자 알고리즘을 적용하는 종전의 방법보다 훨씬 더 효율적이며 유전자 알고리즘과 다단계 기법의 이상적인 결합이라 할 수 있다. 분할 결과에서도 타 알고리즘에 비하여 우수하거나 비슷한 결과를 얻었다.

In this paper, we propose a hybrid approach of combining $A^*$ and Genetic algorithm in the path search problem. In $A^*$, the cost from a start node to the intermediate node is optimized in principle but the path from that intermediate node to the goal node is generated and tested based on the cumulated cost and the next node in a priority queue is chosen to be tested. In that process, we adopt the genetic algorithm principle in that the group of nodes to generate the next node from an intermediate node is tested by its fitness function. Top two nodes are selected to use crossover or mutation operation to generate the next generation. If generated nodes are qualified, those nodes are inserted to the priority queue. The proposed method is compared with the original sequential selection and the random selection of the next searching path in $A^*$ algorithm and the result verifies the superiority of the proposed method.

A web-based model for implementation of mobile compliance analysis system for software contents is proposed. It is said that the content is compliant if the content can be executed properly in mobile environment. The mobile compliance analysis of contents is very important because contents can't be serviced if they arc not proper for mobile environment. The categories of mobile compliance analysis for software contents are proposed. The model of this paper uses the Factory Method pattern and the Facade pattern. The workflow of the s${\gamma}$stem is described through collaborations of classes in the model. As a case study, core Java APIs for implementation of the model arc represented and the mobile compliance analysis system for HDML contents has been built. The model is flexible so that it is easy to add new modules or remove some modules for contents analysis. Although the model is based on the JSP and Java beans, it can be expanded to support any other programming technique such as EJB.

The current study aims to address the relationships among conflict, person-organization fit, and workers' turnover intention. Specifically, it aims to examine whether person-organization fit mediates the relationship between conflict in team and turnover intention, also trust in leader moderates the relationship between person-organization fit and turnover intention. The empirical analysis shows that conflict is positively associated with turnover intention and have a negative impact on objective-value fit. The relationship between conflict and turnover intention is mediated by the person-organization fit. Trust in leader moderates the relationship between person-organization fit and turnover intention. The findings address the issue in terms of the mechanisms between conflict-turnover intention and the importance of trust in leader for an effective management of conflict in work teams.

This descriptive study is aimed at examining the effects of the person-environment fit of general hospital nurses on organizational commitment and career commitment. Data was collected by conducting a questionnaire survey of nurses in four general hospitals in Gyeongnam from February to March 2023, and 210 responses were analyzed using the statistical software SPSS 21. The research results are as follows: Person-job fit and person-organization fit were found to be significant influencing factors on organizational commitment, with an explanatory power of 48.5%. For career commitment, person-job fit, person-organization fit, and person-supervisor fit of the person-environment fit all emerged as significant influencing factors, with an explanatory power of 57.5%. Since person-organization fit has the highest impact on both organizational commitment and career commitment, nursing managers should prioritize the consideration of relevant factors in personnel management.
