This study examined the social perceptions on the women work force in Korean service industries. 100 questionnaires per each of five service industries, hotel, PCS, department store, general hospital and bank (500 altogether) were distributed to general consumers to measure perceived service quality and perceptions on the women employees in the those service industries. It was found that consumers were not very satisfied with the service quality of the industries. They felt the necessity of women workforce in service industry and agreed to that women employees posessed management quality and had potential to develop.

Crime has become one of the major problems in modern society. Even though visual surveillances through closed-circuit television (CCTV) is extensively used for solving crime, the number of crimes has not decreased. This is because there is insufficient workforce for performing 24-hour surveillance. In addition, CCTV surveillance by humans is not efficient for detecting dangerous situations owing to accuracy issues. In this paper, we propose the autonomous detection of dangerous situations in CCTV scenes using a deep learning model with relational inference. The main feature of the proposed method is that it can simultaneously perform object detection and relational inference to determine the danger of the situations captured by CCTV. This enables us to efficiently classify dangerous situations by inferring the relationship between detected objects (i.e., distance and position). Experimental results demonstrate that the proposed method outperforms existing methods in terms of the accuracy of image classification and the false alarm rate even when object detection accuracy is low.

Sweden has one of the world's most progressive and comprehensive childcare systems; synonymous with quality, it is the envy of many other countries. The purpose of this study was to investigate background factors important to the development of the Swedish childcare system and the current childcare policy and system. This study found that underpinning the Swedish childcare system is not only the expectation that men and women will participate equally in the workforce, child rearing, and domestic life but also an awareness of the right of children to development and education. Implementation of the Swedish childcare policy has provided for easy access and affordable childcare centers following principles of childcare universalism. This provides practical suggestions for the Korean childcare policy and system.

The Korean government has implemented various policies such as establishing new major/department and operating a variety of education programs related with cybersecurity. However, it has not yet been constructed virtuous cycle that can provide appropriate education and training to professionals with the high level and quality. In this study, by surveying and analyzing satisfaction about education and training program aimed at employees in public sector who are in charge of cybersecurity, we suggest the direction of education and training for cybersecurity experts required at the national level.

This study aims to explore field cases of social farming programs for the youth's rural in-migration and to suggest the political and practical directions of the initiative of social farming in Korea. Two cases of social farm were selected and one operators and two participants of each farm were interviewed. The results are as follows. First, the participants had a firm priority that social farming is based on farming activities and places, and recognized it as the practice of embracing socially vulnerable groups. Second, the hosts were running their social farms based on their own understanding of social farming, which turns out to show different characteristics of the program. Third, the participants joined the program with the motivation of having an experience of rural life, exploration of career paths, and a need a need of community settlement, restructuring their experiences. Based on these results, the direction of social farming for youth's rural in-migration was suggested.

In this paper, we analyze an N-design call center with skill-based routing, in which one pool of agents handles two types of calls and another pool of agents handles only one type of calls. The approximate analysis is motivated by a computational complexity that has been observed in the direct stochastic approach and numerical method for finding performance measures. The workforce staffing policy is very important to the successful management of call centers. So the allocation scheduling of the agents can be considered as the optimization problem of the corresponding queueing system to the call center. We use a decomposition algorithm which divides the state space of the queueing system into the subspaces for the approximate analysis of the N-design call center with two different types of agents. We also represent some numerical examples and show the impact of the system parameters on the performance measures.

This study aims to conceptually identify the circular causal-relationship which is structured between downsizing and technological innovation in organization. First, through the literature review concerning downsizing and (technological) innovations, we have outlined the conceptual building blocks and research boundaries in this field. Second, we used system thinking method to accomplish our research purpose. The research findings are as follows. First, the promotion of financial resources by downsizing have trade-off relations that have negative of effects in short terms, but positive effects in long time. Second, workforce reduction by downsizing usually has negative influence on employees. Third, capital reduction by downsizing generates not only the climates of cost-cut but also the fact that although the climates may increase economic performance in short terms, it may interrupt technological innovations in long terms. In conclusion, this theses suggests that the relationship of downsizing and technological innovations have complex causal and feedback structures. Therefore, the results of this thesis propose that the argument or practices of downsizing with partial emphasis is very dangerous. Finally some limitations are also discussed.

The production, storage, processing and distribution of information is fast becoming a major economic activity for many nations of the world. The basic idea of this study is that knowledge and information are becoming the strategic resources and transforming agents in the information society. Therefore, in order to cope with successfully the transition toward the information society, the development of measurement tools and social indicators is essential. The purpose of this study is to fulfill three major objectives with regard to the analysis of the information sector in the information society. (1) This study suggests the theoretical definitions and social indicators of the information society. (2) This study investigates an empirical study of the information sector consisting of information industry, information workforce, and information indicator of the selected nations. (3) It advances theoretical explanations of the major factors of the growth of the information sector, and develops theoretical hypothesis and explanations of the information society.

Namhae chemical is one of the largest fertilizer manufacturing company in Korea which company has operating 4 unit agitator gear boxes and producing variety kinds of fertilizer production. The gearbox operating temperature of agitator is approximated in $55^{\circ}C{\sim}90^{\circ}C$ and required to keep operating continuous without stopping. The system required high performance oil and longer oil drain interval as limited workforce in maintenance team. It was lubricated by mineral gear oil of ISO VG 320 and also need to change to new oil frequently. Namhae Chemical would expect to keep stable operating condition without shut down and consider, lower cost of operation and equipment protection.

The risk of facilities in catenary is increasing because the railway section extension and high-speed train service. And visual check of workforce is not enough time to maintain the extensive railway facilities. Accordingly, The technical development trend of maintenance of railway facilities can be seen by automation and application of IT technology, especially the mechanization work and the information technology are spreading in the maintenance work of the train line solved by manpower. In this paper, we describe the method by obtaining the cantilever image using acquisition device and pole inspection system in high speed vehicle, to check the variation of the cantilever component using image processing.
