The basic goal of urban safety is to support citizens' quality of life and city competitiveness, and its importance is increasing. Since the risk of disasters is growing, there is a growing demand from society for minimizing the damage by preventing and responding to them in advance. In case of urban governments, securing safety emerges as one of the most important policy tasks due to natural disasters such as heavy rain and heavy snow and human disasters such as various accidents. Recently, it is emphasized the necessity to increase the prevention effect through disaster analysis using Big Data. This study examined paradigm change of disaster safety management using big data centering on Seoul city. In particular, the study tried case analysis from the viewpoint of maximizing effective government services for disaster safety management, and sought the strategic meaning in connection with the ordinance.

Because bridges can cause more significant damage than other infrastructure a certain level of safety shall necessarily be secured for users. As most of bridges' service life become 20-30 years there will be a dramatic increase in the maintenance and repair cost but the budget and human resource will be limited. Asset management technique can help the efficiency in maintenance and budget management with the limited resource. For its application, there must be a way to evaluate how bridges provide service to users. The level of service can be quantified by a performance measure. This study introduces performance measures and an evaluation process for the determination of level of service. The evaluation results will be used as a fundamental information in the determination of maintenance/repair/management targets and in the decision making process of the bridge asset management.

The saving of time, which is defined as the demand from passengers and the supply from the urban railway, must be balanced. The selected factors influencing on the balance are the traffic, customer contact facilities, the number of failures, customer complaints(VOC), passenger moving time and transfer stations. Also, the overall ratio of SMRT's 4 lines is generated by differentiating the rate of each attribute in each factor. This is not only to differentiate the stations with peculiar factors but also to standardize criteria of the personalized services. Furthermore, as part of standardization, standard drawings of facility management are prepared for the improvement on the management of human resource and material. The drawings include passenger moving lines, location of safety incidents and also indicate the rating of the factors in each station and overall evaluation rating. In conclusion, this thesis aims to improve customer satisfaction constantly by reducing passenger moving time, through the differentiated management of each station.

The International Maritime Organization is developing a maritime safety system called eNavigation in order to effectively respond to accidents occurring on board vessels. Korea is actively participating in the development of eNavigation and is developing Korean eNavigation by adding its own concept to eNavigation of the IMO. eNavigation is designed to provide various functions for marine safety. The data required for each function is various such as spatial data, relational data, file, weather grid. Therefore, there is a need for a system that can appropriately provide heterogeneous data suitable for eNavigation to each eNavigation's service system. In this paper, we analyzed the kinds of data needed for e-Navigation and designed the architecture of heterogeneous data service system that could provide these data properly.

As of 2022, the number of Internet sites for public institutions registered on the 'Government 24' website (www.gov.kr) of the Ministry of the Interior and Safety is 17,000. The direct transfer takes a lot of human and material resources and time between the records-producing institution and the records-management institution that manages websites as records. In addition, it is practically difficult for records management institutions to migrate and operate various software and application technologies required to run each website. A method of automatically collecting websites from a remote location using web crawler software is used domestically and abroad to overcome these practical limitations. This study compared the performance of the web crawler required to collect and manage public Internet websites as records remotely. The most suitable web crawler was selected through a step-by-step review of several web crawlers from previous studies and other literature. Several public agency websites were applied to compare the actual performance of the crawlers in the evaluation process. The study provides empirical and specific performance comparison information for organizations that need to choose a web crawler.

Since Korea experienced a 'jobless growth' in 2003, creating jobs in the service sector has been considered as a top priority employment agenda. However, despite high employment outcomes in services, labor productivity remains stagnant in the service sector in recent years. A great deal of concern has been raised regarding newly created service jobs. Critics say low productivity in the service sector will harm the engine of economic growth in our country. This paper investigates the side of the demand for quality of labor, namely, the demand for skills as one of the main source of low productivity in the service sector. To analyze the changes of skills demand, this paper suggests the concept of job-based skills instead of worker-based skills and presents the way of constructing measures of job-based skills. By means of common factor analysis using job information in the Korean Dictionary of Occupational Titles, I extract 4 direct measures of job-based skills, such as cognitive skills, physical skills, fine skills, interactive skills. These skill measures are used to explore and to test how the skill structure changed in the service sector during 2002-2006. Empirical Results show that whereas the goods sector makes progress toward upskilling being represented by increased cognitive elements and softenization of tasks, the service sector, although high-educated workers increased, exhibits trends of deskilling in the sense of job-based skills during 2002-2006 in Korea. The trend of deskilling however does not seem a general aspect in the overall service sector. Rather, it seems a compound process that high-skilled jobs are created, but, on the other hand low-skilled jobs requiring physical labor are produced at the same time.

The purpose of this research is to understand the effects of environmental uncertainty on transaction characteristics, industry factors, and performance in Korean franchising markets. This research tried to investigate both the characteristics of B-to-C service factors and B-to-B industry factors of franchising industry from the perspectives of CLalt, trust, communication, and other important variables. Hypothetical research model was proposed and, by using SPSS and AMOS, research hypotheses and structural equation models were empirically tested and supported. The results showed that environmental uncertainty has negative effects on relationship characteristics and industry characteristics of franchise. Trust showed positive impact on the performance. Managerial implications and limitations of the study results were also discussed. Future research direction was suggested.

In this study we surveyed service satisfaction for the start-up support program and measured the relative importance of the factors that influence service satisfaction. The five service factors(physical facilities, finance and accounting, human resources, marketing, product development) were used to measure service satisfaction. Typically, the relative importance of predictors is assessed by simply comparing their standardized regression coefficients. However, when the predictors are correlated, regression coefficients cannot be used to explain variance shared by two or more predictors. The dominance analysis used by many researchers in recent years to measure the relative importance of predictor variables. In this article, we applied it in satisfaction research for the start-up support program. The results obtained by the dominance analysis are compared with the results obtained by multiple regression analysis. And satisfaction and relative importance of the five factors are analyzed by entrepreneurship motivation. These findings will contribute to the marketing research field relating to service satisfaction. Service satisfaction for the start-up support program can improve based on this study.

The light rail transit (LRT) having bus lines as subsystem is being constructed or planned in the suburban area of metropolitans and medium size cities. However, there is difficulty in establishing the service coverage (SC) of the LRT because the LRT is a completely new transit mode in Korea. The purpose of this study is to provide the basic data and techniques to be used for establishing the SC of the future LRT by understanding the SC characteristics of buses and subways and building models to estimate the walking distances of their users. Busan City is selected as the study city and the SC's of buses and subways are surveyed simultaneously. A total of 9 variables for 82 stations are collected and the cluster analysis is conducted about the variables. The station areas are divided to three types of CBD (Central Business District), sub-CBD and regional center based on the analysis. A station in each area is selected as the study station. At the walking distance (WD) analysis for each mode, the 80 percentile WD of the subway is 672 m and that of the bus is 472 m. In comparing the SC's of both modes by the type of station areas, there are not significant differences between the SC's of sub-CBD and regional center except CBD. At analysis of the relationship between the personal attributes and the WD, for subway users the WD of female is longer than that of male and apartment residents use subway more positively than single house residents do. For the models to estimate the walking distances, the simple regression models were built employing the income as independent variable by dividing the stations into CBD abd non-CBD stations.

The purpose of this study is to provide basic data in order to improve service quality based on empirical analyses about a relationship among positive psychological capitals, service quality, and job satisfaction of professional care workers under the Long-Term Care Insurance in South Korea. In this study, total 430 numbers of the workers who were currently working in nursing homes for the elderly at the cities of Ansan, Anyang, Bucheon, and Kwangmyeong in Gyeonggi Province, South Korea, participated in self-report questionnaires. Only 393 questionnaires were used for the final analyses after excluding the ones that neither were not returned nor didn't completed it all. These are major results. First, positive psychological capitals affect positively on service quality. Second, job satisfaction works as a mediating effect in the process of positive psychological capitals affect on service quality. Based on above results, it is possible to suggest it as down below. First, it is required to have policies that will be helpful for both positive psychological capitals and capacity building through human resource management in systematic approaches. Second, it is also required to acknowledge that having positive psychological capitals is effective to improve both their job satisfaction and service quality. Therefore, it is necessary to change environmental circumstances in relevant institutions where this acknowledgement will be applied.
