  • Almost all companies have paid much attention to the safety management ranging from maintenance to operation even at the stage of designing in order to prevent accidents, but fatal accidents continue to increase throughout the world. In particular, it is essential to systematically prevent such fatal accidents as fire, explosion or leakage of toxic gas at factories in order to not only protect the workers and neighbors but also prevent economic losses and environmental pollution. Though it is well known that accident probability is very low in NPP(Nuclear Power Plants), the reason why many researches are still being performed about the accidents is the results may be so severe. HRA is the main process to make preparation for possibility of human error in designing of the NPP. But those techniques have some problems and limitation as follows; the evaluation sensitivity of those techniques are out of date. And the evaluation of human error is not coupled with the design process. Additionally, the scope of the human error which has to be included in reliability assessment should be expanded. This work focuses on the coincidence of human error and mechanical failure for some important performance shaping factors to propose a method for improving safety effectively of the process industries. In order to apply in these purposes into the thesis, I found 63 critical Performance Shaping Factors of the eight dimensions throughout studies that I executed earlier. In this study, various analysis of opinion of specialists(Personal Factors, Training, Knowledge or Experience, Procedures and Documentation, Information, Communications, HMI, Workplace Design, Quality of Environment, Team Factors) and the guideline for construction of PSF were accomplished. The selected method was AHP which simplifies objective conclusions by maintaining consistency. This research focused on the implementation process of PSF to evaluate the process of PSF at each phase. As a result, we propose an evaluation model of PSF as a tool to find critical problem at each phase and improve on how to resolve the problems found at each phase. This evaluation model makes it possible to extraction of PSF succesfully by presenting the basis of assessment which will be used by enterprises to minimize the trial and error of construction process of PSF.

  • This essay examines the motivations, goals, and assumptions of those who are participating in the appropriate technology movement in contemporary South Korea. In addition to analyzing books, articles, presentation materials, and media reports written by or about the "appropriate technologists," I have interviewed a few of them to hear their thoughts on appropriate technologies as well as inappropriate technologies. They choose to work on appropriate technology out of their good will for people in need, their Christian faith, and their pride in Korea's rapid and successful development. As a result, the appropriate technology movement in Korea does not engage in a critical evaluation of current sociotechnical systems, but instead takes an ethical and paternalistic stance in accepting and improving the given situation. Its apolitical character is effective in drawing a large number of participants, but it also limits their imagination and the movement's potential influence. Moreover, the movement's focus on "the other 90%" leads the participants to frame appropriate technology as something for "them" or "locals" rather than as something for "all of us." This essay concludes by suggesting that the appropriate technology movement in Korea should expand its scope from an ethical pursuit of technology to a political engagement with technology.

  • Semicurrent records are documents that are stored and managed in a separate section because they are infrequently referred to in work. The semicurrent records management stage is when records from the processing department are collected for the first time, serving as a bridge between the current and noncurrent records. For systematic records management, records management at the semicurrent stage is vital. Although Korea has established numerous records centers, various problems remain in the records management environment. In response, this study examines the United States' semicurrent records management system and discusses the features that are different from that of Korea. For this purpose, the records management system of the United States was selected as the scope of research and is analyzed through its records schedule, transfer, and appraisal. The data for the research were obtained through the relevant records management law, guidelines compiled by related agencies, and written inquiries for the records management officer. Through these methods, this study was able to identify the relationship between the federal agency and the Federal Records Center, the introduction of new technology in the aspect of transfers, the privatization of records preservation, and the status of the Federal Records Center as a passive appraisal entity.

  • In general, seafarer's human error is considered to be the preponderant muse for the majority of maritime transportation accidents in a merchant ship. The implementation techniques for Human Error Model (HEM) to assess possible accident risk by deck officers including captain, chief officer, second mate and third mate are described in this study. The scope of this work is focused to 642 deck officers in the ship management company with 130 vessels. At first, HEM can be constructed through the statistical analysis and expert's brainstorming process with human data to 642 deck officers. Then the variables $\upsilon$ for the human factors, the evaluation level EP($\upsilon$) for $\upsilon$, the weight $\alpha$ of $\upsilon$, and the title weight $\beta$ of each deck officers can be decided. In addition, through the analysis of ship's accident history, the accident causation ratios by human error ${\gamma}_H$ and by external error ${\gamma}_B$ can be found as 0.517(51.7%) and 0.483(48.3%), respectively. The correlation coefficients to $\upsilon$ are also shown significant for a 95% confidence interval (p < 0.05) for each coefficient. And the validity of HEM is also surveyed by the analysis of normal probability distribution of risk level RL to each deck officer.

  • Recently as return farmers has been increased rapidly, the introduction of a system of rental housing is being considerated in order to induce regional fixation. It was examined organizational management, business scope of rural type rental housing, management role, through the analysis about the management realities of the business of similar form Rural-Fishing New Town project. Jangseonggun and Hwasungun have maneged rental housing 280ho in Rural-Fishing New Town project. It is large village among Rural Rental Housing. And these counties have organized the complex on a large scale among the rental housing. Local governments have managed and operated directly, also these governments have two different methods for the co-management, and the way of making payment. Rental housing management services are divided into rental management, housing management, tenant management. Rental management services such as residents of recruitment, tenants and retreat, rent collection and the storage, management and leasing promotion of the cantilever, surveys of residents. Housing management services such as check of various facilities, maintenance and maintenance work, security and cleaning and daily facility management. Tenant management is life management in connection with housing welfare. In the rural type of rental housing, there are few cases to operate a management office. It is often supplied by rental housing to buy a house or vacant land within the existing village. In this case, by utilizing community facilities within the existing village instead of establishment of extra facilities,It doesn't need to make payment for maintenance fee. In the smaller complex than No. 20, it is self-managed by the tenants in order to reduce the administrative costs and specify the necessary municipal manager. Organization form can be maneged directly from local governments and part of for the management of the building can be employed a mixed management system to delegate management to private organizations such as non-profit organizations or neighborhood association. Tenant management helps people who move in a rental house live on stable circumstance in there area by connection with the program of life support.

  • Process mining in big data environment utilize a number of data were generated from the business process. It generates lots of knowledge and insights regarding implementation and improvement of the process through the event log of the company's enterprise resource planning (ERP) system. In recent years, various research activities engaged with the audit work of company organizations are trying actively by using the maximum strength of the mining process. However, domestic studies on applicable sales auditing system for the process mining are insufficient under big data environment. Therefore, we propose process-mining methods that can be optimally applied to online and traditional auditing system. In advance, we propose continuous monitoring information system that can early detect and prevent the risk under the big data environment by monitoring risk factors in the organizations of enterprise. The scope of the research of this paper is to design a pre-verification system for risk factor via practical examples in sales auditing. Furthermore, realizations of preventive audit, continuous monitoring for high risk, reduction of fraud, and timely action for violation of rules are enhanced by proposed sales auditing system. According to the simulation results, avoidance of financial risks, reduction of audit period, and improvement of audit quality are represented.

  • The purposes of the study were to establish HACCP-based standards and guidelines for conducting a plan review to build, or renovate, hospital food service establishments, and ensure the safety of foodservice and reduce the risk of food borne illness. The scope of the study included suggestion for the planning of hospital foodservice facilities: layout, design, equipment and modeling. The results of this study can be summarized as follows: 1) The development of a foodservice facility plan based on the results of a survey, literature reviews and the results of interviews with foodservice managers from 9 general hospitals. This was composed of operational policies in foodservices, layout characteristics, space allocation, selection, design, specification standards for equipment and the construction principles of foodservice facilities. 2) Two foodservice facility models were developed, one for general hospitals with 900 beds (2,000 patients and 2,500 employee meals per day) and the other for general hospitals with 300 beds (600 patients and 650 employees meals per day). 3) The suggested kitchen space requirements for the foodservice facility models were 341.2 ㎡ (W 17,100mm x L 23,700mm) and 998.8㎡ (W 35,600mm x L 32,800mm) for the 300 and 900 beds hospitals, respectively, with both designs being rectangular. The space requirements for the equipment, in relation to the total operational area, in terms of ratios were 1:3.5 and 1:3.8 for the 300 and 900 beds hospitals, respectively. The recommended space allowances per bed for the developed foodservice facility models were 1.15 ㎡ and 1.11 ㎡ for the 300 and 900 beds hospitals, respectively, which were increased by more than 30% compared to those suggested in the precedent study, and considered appropriate for the implementation of the HACCP system. 4) The hospital foodservice facilities plans and models were developed based on the general sanitation standards, guidelines and the HACCP system, and included foodservice facility layout, product flow, physical separation between contaminated and sanitary areas, foodservice facility specifications with a 1/300 scale for a 300 bed, and a 1/400 scale for a 900 beds blueprint. 5) The main features of the developed foodservice facility plans and models were; physical separation between contaminated and sanitary areas to prevent cross contamination, product flow in one direction from the arrival of the raw material to the finished product, and separation of different work areas and the process of receiving & preparation of products, refrigeration & storage, cooking, assembly, cleaning & disinfection, employee areas and janitorial facilities. The proposed models from this study were presented as examples for those wanting to build, or renovate, their facility for the production of foods.

  • Purpose: This study aims to examine the research output in the field of nursing at the global level during the last two decades, viz., for the period 1996-2015, with special reference to India. Some of the aspects examined include the research growth in nursing literature during the period of study, leading nursing research countries at the regional and global level, and citation analysis. Scope and Methodology: This study is global in nature, but emphasis has also been laid on India's research contribution in nursing at the global level. Aspects like regional contribution to the nursing research output have also been assessed. This study is purely based on secondary data retrieved from SCImago Journal and Country Rankings. The figures in the study are based on one particular database and are not exhaustive; hence they simply reflect a trend in nursing research at the global level. Findings: During the period 1996 through 2015, a total of 550,490 research articles were published across the world by 212 nation states at an average of 2,596 articles from each individual country. On average, during the period of study, the number of nursing research publications grew at the rate of 7.36% each year. North America has emerged as one of the leading nursing research continents of the world by publishing 218,614 research articles, constituting 39.71% of the global nursing research output. The U.S. and U.K. are the world's two leading nursing research countries, which contributed 193,819 and 61,730 research articles respectively, comprising a 35.21% and 11.21% share of global nursing research output. India and China, apart from being the two fastest growing nursing research countries, have the potential to meet the global human resource demand in the field of nursing, given the skilled and trained human resource both these countries possess in nursing. Social Implication: There is always a need to share working knowledge in some professions and nursing is one of them. There cannot be a better medium than linking practice with theory through the research medium. Metric studies in turn help to get a better idea about the amount of work done in any given field at the national and international level, thus identifying the need thereof to improve upon those areas where there is research lag.

  • In the absence of a research study on meta-analysis in terms of program development, the purpose of the study is to analyze the contents of the meta-analysis research studies which has been conducted for 18 years, and is to identify the level of program component evidence for the development of social work program. In order to achieve these purposes, the study analyzed the feature and usefulness of the 110 meta-analysis studies(5,781 program evaluation studies)published from 2010 to June 2017 in major academic journals related to the areas of the social welfare, psychology, counseling and health. The major findings are as follows. The 110 meta-analysis studies tended to narrow down the scope of the population, problems, and program types, but they also included a lot of heterogeneous types. In the statistical methods, there were relatively few studies to explain the factors behind the heterogeneity of program effectiveness. In addition, researchers tended to select program components arbitrarily with bias on specific components. The important program components with the statistical validity are as follows; the age of the subjects, the severity of the problem, the expertise of the providers, and the strength and activities of the intervention, The academic meanings of the study results was discussed, and the direction of future research was presented to increase the usefulness of the metaanalysis for program development.

  • In 97hu2200, the Supreme Court of Korea suggested five requirements to apply the doctrine of equivalents, i.e. identity of problem-solving principles, interchangeability, ease of interchangeability, exception of known arts and file-wrapper estoppel. There have been arguments on whether the standard of ease of interchangeability could be regarded as the same as the obviousness standard in deciding patentability. The side who thinks that they are different (hereinafter, the side of difference) considers that the standard of ease of interchangeability is narrower than the obviousness standard. This side criticizes the side who thinks that they are the same each other (hereinafter, the side of the same) on the reason that doctrine of equivalents can be overly expanded. On the other hand, 'the side of the same' argues that every accused invention having no inventive step from the perspective of the patented invention should be considered to infringe. 'The side of the same' points that if the standard of ease of interchangeability is considered as narrower than the obviousness standard, 'grey area' should exist where the patent law cannot work. The difference between the two side may cause contradictory results in the decision of infringement under the doctrine of equivalents. Because 'the side of difference' construes claims narrowly than 'the side of the same,' an accused invention in the grey area is not regarded to infringe. 'The side of the same,' however, considers the accused invention to fall into the scope of the patent under the doctrine of equivalents. This paper concludes that the standard of ease of interchangeability should be regarded as the same as the obviousness standard from the perspective of economics of innovation.
