This paper proposes a ontology of tree structure approach for adaptive object recognition in a situation-variant environment. In this paper, we introduce a new concept, ontology of tree structure ontology, for context sensitivity, as we found that many developed systems work in a context-invariant environment. Due to the effects of illumination on a supreme obstinate designing context-sensitive recognition system, we have focused on designing such a context-variant system using ontology of tree structure. Ontology can be defined as an explicit specification of conceptualization of a domain typically captured in an abstract model of how people think about things in the domain. People produce ontologies to understand and explain underlying principles and environmental factors. In this research, we have proposed context ontology, context modeling, context adaptation, and context categorization to design ontology of tree structure based on illumination criteria. After selecting the proper light-ontology domain, we benefit from selecting a set of actions that produces better performance on that domain. We have carried out extensive experiments on these concepts in the area of object recognition in a dynamic changing environment, and we have achieved enormous success, which will enable us to proceed on our basic concepts.

This study was designed to examine the degree of empathic ability, gratitude disposition, and job satisfaction, and identify that the impact on job satisfaction of psychiatric nurses. Participants were 196 psychiatric nurses from 8 psychiatric hospitals in Korea. Data were collected from October 8 to 20, 2016 and were analyzed using independent t-test, one-way ANOVA, Pearson correlation coefficients and hierarchical multiple regression with the SPSS WIN 22.0 program. The mean score of job satisfaction was $3.3{\pm}0.34$, empathic ability was $3.5{\pm}0.28$, and gratitude disposition was $4.0{\pm}0.59$. The psychiatric nurses' empathic ability and gratitude disposition affected their job satisfaction, accounting for 18.5% of the total variance. Empathic ability influenced job satisfaction significantly (B=0.52, p<.001) for 17.0% of the variance. This study suggested that the development of training programs for improving job satisfaction needs to consider their empathic ability and gratitude disposition of psychiatric nurses.

This paper aims to examine the contribution that the ERVET System, composed of ERVET and real service centers, has made to both governing and enhancing regional innovation system in Emilia Romagna, Italy. ERVET and real service centers both establish and perform plans for regional development and innovation. But they also try to provide varieties of real services for local firms, mostly small and medium-sized firms. Attempting to promote innovation networks between industries, universities and administrative bodies, the ERVET System has become a core intermediary agency of Emilia Romagna in both governing regional innovation system and enhancing regional innovation capabilities. Based on the case of the ERVET System, we propose a policy recommendation. As local governments in Korea have still been less autonomous but hierarchical, it would be difficult for them to make the decision effectively on regional innovation and development initiatives. In this context, we suggest that regional development agencies need to be established on the basis of benchmarking advanced cases in Europe and North America such as the ERVET System.

The purpose of this study is to examine the effects of park type and inner elements of parks on the number of walking days of walking out of Ulsan Metropolitan City, And to make policy suggestions for them. The elderly people aged 65 and 1,274 persons or over in Ulsan Metropolitan City were selected as the subjects using the raw data of the 2015 community health survey. A multilevel analysis was conducted using a hierarchical linear model to find out the factors affecting the number of days of walking according to the level of regional level factor according to the five wards of Ulsan Metropolitan City. The number of walking days increased with the number of sports facilities and the number of walking days decreased with the number of amusement facilities mainly used by children. In the case of Jung-gu in Ulsan, the number of walking days was low even though the number of parks and the area of the park were large, In the case of Buk-gu, the number of walking was high even though the number of parks and the area of the park were small. Elderly people in Jung - gu, Ulsan metropolitan city are expected to need a health promotion project to promote walking, and it is necessary for seniors in Buk - gu, Ulsan Metropolitan City to make a good walking environment.

We tried to get useful information from social network analysis on the transaction network for the companies in Busan, Ulsan, Kyong-nam region using more than 80 thousand company transaction data obtained from Korean enterprise data (KED). We found that there are 282 clusters having more than 3 companies when we made clusters composed of the companies having the transactions with each other as the first transaction partners in the region. Most of clusters have a major big company with most of sales in the clusters and have the member companies without the transaction with other cluster's member companies so that they have closed and hierarchical transaction pattern. Analysing the transaction network using the network index, we know that there are small medium size companies playing the central role in the regional transaction network and a few clusters have many transactions with other clusters. Also we found that there are very rare sale transactions to the companies outside the region and many purchasing transactions from the companies outside the region. Policy makers need to try to diversify the transaction patterns and to use the exceptional companies and clusters as the levers.

This study analyzes the influence of the construction of a high-speed railroad on territorial organization in France. After development of a new transportation network, the French territorial organization has been largely modified. Many economic urban areas are modified by their position in the territorial hierarchy according to their condition of connection with the TGV network. At first, spatial convergence is the most important effect of the TGV network construction. Second, the development of a transportation network concentrated in the Paris area has influence as an intensified factor on metropolitan areas and as a weakening factor on middle- and small-sized cities. Thus, this system has risk in increasing territorial imbalance in France. Third, to implant an economic activity zone around new TGV stations, a new town or a new economic center starts to develop. This is going to grow into a second core outside of the old city center so that regional spatial organization is transformed from a mono-polarized(mono-centric) organization to a multi-polarized(polycentric) one. Lastly, the integration of the EU railroad system enhances the concentration of economic activity in European metropolitan areas as each metropolitan area tries to develop more competitive space for its rising position in the global urban hierarchical system.

The purpose of this study was to examine the attitude toward own aging among community-residing elderly and the predictors of the attitude focusing on personal resources, social support, and social participation. Data were collected from 198 elders aged 60+ with the cooperation of several social service center for the aged, senior centers, and senior citizen associations in Daejeon Metropolitan City. SPSS 22.0 software was used for descriptive analysis, correlation analysis, and hierarchical regression analysis. The results showed that (1) the research participant elderly's attitude toward own aging indicated fairly negative perception of their own aging; (2) self-esteem and economic status were statistically significant factors indicating the higher levels of self-esteem and economic status predicting the positive attitude of their own aging; (3) emotional support from family was statistically significant factor that predicted the positive attitude of their own aging; (4) the level of social participation was also statistically significantly associated with the positive attitude; (5) In the full model of all independent variables, the significance of emotional support from family and social participation disappeared, but self-esteem and economic status among personal resources remained statistically significant influential factors. Based on the findings, suggestions for social welfare policy and practice to improve community-residing elderly's positive attitude toward their own aging were discussed.

This study was conducted to investigate the factors that affect the length of stay in hospital for schizophrenic patients. Of the data from the in-depth injury patient surveillance system, the final subject included 2,239 patients with schizophrenia in their final diagnosis. Using SPSS 18.0, a hierarchical regression analysis was performed by sequentially entering the explanatory variables by setting sociodemographic characteristics, discharge characteristics and hospital characteristics as explanatory variables and the length of stay in hospital as a dependent variable. The findings showed that the sociodemographic characteristics had the highest explanatory power and the explanatory power changed when the explanatory variable of the hospital characteristics was added, as opposed to the discharge characteristics. Male, type-1 medicaid, Chungcheong-do and the number of beds were found to be the factors that mostly affect the length of stay. Since this study used the secondary data, it has a limitation in terms of additional variables that could better explain the length of stay for schizophrenic patients. Nevertheless, it has an implication in that it investigated a large scale of data on a national level. For the effort of reducing the length of stay, it is suggested that an effort should be made at the national level, by focusing more on the hospital characteristics as well as the individual characteristics of patients.

This study is executed to investigate convergent factors to job burnout(MBI-GS: Maslach Bunout Inventory-General Survey) among hospital administrative staff. The survey was administered to 201 staff from 9 general hospitals located in J area from Jul. 3rd, 2017 to Jul. 29th, 2017. The structured self-administered questionaries were used. The hierarchical multiple regression analysis shows the following results. The MBI-GS of respondents turned out to be significantly higher in following groups: a group in which Organizational Commitment Questionnaire(OCQ) is lower, a group in which Type A Behavior Pattern(TABP) is higher, a group in which depression(CES-D: Center for Epidemiologic Studies Depression scale) are higher. The results show explanatory power of 52.1%. The results of the study indicate that the efforts, to increase OCQ, and to decrease TABP and CES-D, are required to improve the MBI-GS among hospital administrative staff. The results are expected to be useful for the program and human resource management to related to the MBI-GS among HAS. In the following study, the analysis of structural equation modeling about additional factors of the MBI-GS among hospital administrative staff will be needed.
