Outlier detection is an imperative task to identify the occurrence of abnormal events before the structures are suffered from sudden failure during their service lives. This paper proposes a two-phase method for the outlier detection of Global Positioning System (GPS) monitoring data. Prompt judgment of the occurrence of abnormal data is firstly carried out by use of the relational analysis as the relationship among the data obtained from the adjacent locations following a certain rule. Then, a negative selection algorithm (NSA) is adopted for further accurate localization of the abnormal data. To reduce the computation cost in the NSA, an improved scheme by integrating the adjustable radius into the training stage is designed and implemented. Numerical simulations and experimental verifications demonstrate that the proposed method is encouraging compared with the original method in the aspects of efficiency and reliability. This method is only based on the monitoring data without the requirement of the engineer expertise on the structural operational characteristics, which can be easily embedded in a software system for the continuous and reliable monitoring of civil infrastructure.

This study identified the present state of store and selection criteria of supplier from the regional fashion buyer point of view and examined the effects of the factors of relative impact between buyer and supplier on the relational bond. The interviews and questionnaires were administered to the owners or the sellers of 85 fashion retail stores in Gwangju. For analysis of data, frequency, means, factor analysis, Cronbach's ${\alpha}$ and regression analysis were applied. The results were as follows. First, in the results of examining the actual conditions of store managers for fashion buyers, fashion buyers complained about lengthy travelling and time consumption inconvenience. They also reported decrease in margin and monthly mean sales over last year. Second, the most important selection the criteria for the supplier were product power, followed by a convenient store layout. Finally, higher quality communication, more compromises, and higher dependence were affected with higher satisfaction, trust, and commitment in suppliers; conversely, the trust and commitment of the buyers decreased relative to the increased power of the suppliers.

During adolescence, youths may experience many unexpected changes due to sudden variances. At that time, youths were found to show rebellious or abnormal behaviors due to psychological wounds. These are often caused by psychological wounds oriented at home or at school, which may make some problems in adolescents' self-respect and attachment. In this study, we plan to conduct an analysis of the case of the interior therapy of educational facilities through TBRI (Trust-Based Relational Intervention) to discover how psychological therapy for youths is applied to an interior environment. The cases analysis are conducted based on the three principles of TBRI and the twenty seven detailed keywords within each principle. The research method is oriented on the research of literature focusing on TBRI-related external studies and domestic/external studies of interior therapy. The ranges of the case study are studied in six educational facilities retrieved and extracted from the website 'Archdaily' and from the 2019 Journal of the Korean Institute of Educational Facilities. The research article are concluded that TBRI's principles were applied to shape, finish material, color, lighting, furniture layout, plan layout, sculpture, and built-in-furniture by analyzing the interior therapy of educational facilities according to the elements of TBRI.

The purpose of this study is to identify elements of job crafting impacts on work engagement and individual work performance in Vietnamese commercial banks. The research data, collected from 226 bank officers, uses the quantitative research tools as: Cronbach's Alpha Analysis, Explanatory Factor Analysis, Confirmatory Factor Analysis as well as Structural Equation Modeling. The results of the hypothesis test show that only two hypotheses (H2, H3) are accepted: the impact of cognitive crafting on work engagement of bank officers (H2) and the impact of work engagement on individual work performance (H3). However, three remaining relationships (H1, H4, H5) are not accepted in the study: the impact of relational crafting on work engagement of bank officers (H1), the impact of relational crafting on individual work performance of bank officers (H4) and the impact of cognitive crafting on individual work performance of bank officers (H5). The study results indicate that cognition on job crafting leaves positive impacts on work engagement, leading to individual work performance enhancement. On the other hand, the relational crafting element implies contribution on neither collective nor individual working performances. Furthermore, no direct effect of cognition on job crafting to individual performance has been identified.

In recent years, an increase in deaths and injuries of port cargo handling workers, has raised the need for more effective accident management. The purpose of this study was to evaluate the accident risk for port cargo handling workers and assess ports with high accident risk within the Korean alternative ports using the Entropy & GRA (Grey Relational Analysis). To achieve this purpose, first, 11 Korean ports were selected and the evaluative factors for their outranking evaluation by brainstorming were extracted. Second, the Grey Relational Coefficient of 11 alternative ports was calculated using the GRA. This paper, finally, determined the priority orders of accident risk through calculation of the Grey Relational Grade as the link Grey Relational Coefficient method and the weights of the evaluative factors were calculated by using the Entropy method. In the proposed model, eight criteria such as cargo worker, old cargo worker, work hours, facilities environment, steel cargo volumes, cargo volumes, injury numbers, and death numbers were collected. Busan port was identified as highest accident risk port, and so it should be a top priority to develop a plan to mitigate the risk.

This study analyzes the impact of the experiences of elderly using social welfare organizations in socio-economic deprivation on their relational aggression damage experiences, and verifies the mediating effects of rejection sensitivity. For data collection, 275 of 290 questionnaires, excluding 15 questionnaires with inadequate responses, were used for the final analysis. The SPSS and AMOS programs were used for data analysis through the following procedures. The analysis showed that socio-economic deprivation experiences, relational aggression damage experiences, and rejection sensitivity were higher for the groups of male elderly, higher age, education above college, absence of spouse, and longer institutionalization. The size of indirect effect (${\beta}=.32$) was larger than that of direct effect (${\beta}=.14$), signifying that the indirect impact through rejection sensitivity was larger than the impact of socio-economic deprivation on the experiences of damage by relational aggression. With the above findings, this study makes practical suggestions for institutional measures to reduce the elderly's relational aggression damage experiences and rejection sensitivity and programs on socio-economic deprivation, etc.

The complex documentation involved in power system analysis software require a well-defined and friendly database system. We have developed an object-oriented database management system for power system analysis, and have described load flow analysis and transient stability analysis using object-oriented database(OODB). Database management systems are widely used and achieve high reliability of data management in the engineering fields. However relational database system have shortcomings in application to power system analysis. ill relational database, the data model is too simple for modeling complex data and database languages are very different from programming languages. Object-oriented techniques are sufficiently powerful to support data-modeling requirements of GUI applications. The GUI is implemented using C++ on a MS windows platform. The OODB supports data modeling requirements of GUI applications and the performance is well acceptable for Gill applications.

The hotel industry needs to make the competitive advantage difficult to be imitated in order to remain sustainable in competitive business circumstances. Front-line employees' service-oriented citizenship behaviors(OCBs) can be such a strength from the perspective of organizational system. With an aim of investigating the antecedents of the hotel front-line employees' service-oriented OCBs, this study proposed a theoretical framework linking authentic leadership to service-oriented OCBs with goal commitment as a mediator. A total of 260 cases without missing values have been used for the final analysis and structural equation modeling (SEM) is employed using the SPSS and AMOS 7. It was first found that self-awareness and relational transparency of authentic leadership made a significant impact on their goal commitment while balanced processing and moral perspective failed to influence them. Second. goal commitment influenced all sub-factors of service-oriented OCBs. Third, moral perspective and relational transparency of authentic leadership significantly influenced service-oriented OCBs while self-awareness and relational transparency failed to make it. Finally, goal commitment significantly makes an intervening effect for the relationship between self-awareness & service-oriented OCBs and relational transparency & service-oriented OCBs but failed to intervene the other relationships. The results provide theoretical and practical implications regarding directions of leadership styles and HR management in the hotel industry and suggestions for the further extended studies.

Two component analysis methods based on the fuzzy relational calculus are proposed in the setting of the ordered structure. First component analysis is based on a decomposition of fuzzy relation into fuzzy bases, using gradient method. Second one is a component analysis based on the eigen fuzzy sets of fuzzy relation. Through experiments using the test images extracted from SIDBA and View Sphere Database, the effectiveness of the proposed component analysis methods is confirmed. Furthermore, improvements of the image compression/reconstruction and image retrieval based on ordered structure are also indicated.

This study analyzed the effects of the relational norm factor of food service franchising on the intention to remain, in view of the importance of relational norms, as antecedent variables, to franchisees' perceived fairness to enhance the competitiveness by formation of long-term relationship between interested parties to food service franchising, the franchiser and the franchisee. According to a questionnaire survey, more than 100 franchisees that recorded three business years in Seoul, Incheon and Gyeonggi area were selected for convenience sampling. Then, among them, 515 effective samples were analyzed. For statistical data, detailed types of analysis were performed by using AMOS 17.0, such as factor analysis, exploratory factor analysis, confirmatory analysis and frequency analysis. The purpose of this study was to examine the relationship between the franchiser and the franchisee by arranging relational norm factors for the relationship to be suitable for the current situation of Korea, instead of Western-style theory-based relationship marketing, and by understanding a connection between perceived fairness and management achievement-related variables, and to make a conceptual framework for building a positive relationship between the franchiser and the franchise in future food service franchising industry. Moreover, it aimed to increase franchisee satisfaction and results including re-contract according to perceived positive relationship value on the franchiser and to make contribution to find and show the proper direction for development of the Korean-style food service franchising system.
