The interest of version management is increasing in electronic commerce requiring data mining and documents processing system related to digital governmentapplications. In this paper, we define a change set that is to manage historicalinformation and to maintain XML documents during a long period of time and propose several storage policies of XML documents using a change set. A change set includes a change oper-ation set and temporal dimensions and a change operation set is composed with schema change operations and data change operations. We pro-pose three storage policies using a change set. Three storage policies are (1) storing all the change sets, (2) storing the change sets and the versions periodically. (3) storing the aggregation of change sets and the versions at a point of proper time. Also, we compare the performance between the existing storage policy and the proposed storage policies. Though the performance evaluation, we show that the method to store the aggregation of change sets and the versions at a point of proper time outperforms others.

This study closely examines domestic supplementary measures implemented for Free Trade Agreements (FTA) concerning the agriculture and livestock industry and finds out their problems and put forward improvement measures in terms of their system and contents. The systematic problems with previously established supplementary measures are as follows. First, the existing short and long term measures does not comply with each FTA's special and unique economical, political and legislative purpose. Secondly, they focus on improvements for individual FTAs. They must be holistic and integrative considering all FTAs, thus producing synergy to reach better policy overall. Lastly, FTA policies and the measures must reflect the expanding size and scope of regional economic integration. Problems or concerns in existing supplementary measures include first, flexible financing. The government hands out loans to players in the industry based on assets but these loans must be flexible to market interest changes and must include reduced mortgage rate options. Secondly, rigid standards that trigger direct loss prevention, establishing maximum and minimum loan limits, and developing a comprehensive standard for identifying crops to support are all problems that need to be addressed. Thirdly, education of next and future agricultural generation is paramount in building a competitive workforce. Fourthly, the government must identify industries lacking in performance or short in supply to cease or reducing funding. Last but not least, the government should actively search for new markets for export and produce long term road maps for export growth.

The concept of workers' participation in occupational health was introduced to Korea recently in relation to primary health care in occupational health. But there is confusion and debate about workers' participation concept. The purpose of this study was to review the concepts of workers' participation and to conduct evaluation the workers' participation status in occupational health and safety, 394 workers and 54 employers (5.6%) in north area of Kyunggi-Do, were selected and interviewed with a questionnaire by a trained interviewer from August to September 1990. In general, the concept of workers' participation is based on industrial domocratisation and Declaration of Human Rights which had been powerful ideologies in labor movement. Contrary to workers' participation, community participation is rooted in the Health Rights. So, it is necessary to consider concept of workers' participation to improve participation. The results of survey were as follows. 1. Most of companies (71.75) carried out occupational health education to workers in study area. 2. The Occupational Safety and Health Committee (OSHC) were set up in 24.1% among the study companies, and 72.7% of workers among respondents thought that OSHC was helpful to workers health. 3. The workers signed his name to personal health report in 43.1% and the rate of participation in occupational environment examination was 54.9%. 4. The workers prefer the OSHC (39.3%), owner (35.1%) and union (25.8%) as a occupation health organisation, but owners prefer OSHC (54.5%), manager (43.2%) and union (2.3%). 5. Among the factors of the general characteristics, the existence of labor union was a major determinant of workers' attitude and level of workers' participation. As we have seen, most levels of workers' participation are low in occupational health. The variable of existence of labor union among the factors was a ma determinant of workers attitude and level of workers' participation. Therefore, in order to promote workers health, it is necessary to ponder long deeply on occupational health care system under the viewpoint of workers' participation.

Purpose: Expecting a new system of nursing security for elderly in operation in 2007, a substantial expansion of nursing facilities for elderly and quality management of those facilities are imperative now. Therefore. specific quality management measures or schemes which could be used for the operation of small-scale nursing homes are in urgent need. The purpose of this study was to develop a Quality Management Index(QMI) to guide Nursing Home management. Method: This study developed a QMI for small-scale nursing homes, which focused on quality management in structural dimensions such as environment, staffs, local community network, atmosphere, and quality management in process dimensions such as nursing, communication, resident satisfaction. The QMI developed in this study is based on extensive review of literature and the actual experiences of nursing home operation. It consists of 7 dimensions, 39 components and 148 indexes, which have been verified by three times validity tests of experts group. Then the QMI was used to evaluate the quality management levels of nursing homes in Korea. Result: In sum, after analyzing all nursing homes in Korea operated by nurses, this study found that there were significant differences of quality management level among facilities in several dimensions such as environment, staffs, local community connections, communication. In dimensions such as nursing, atmosphere, resident satisfaction, however, little differences of quality management level among facilities were reported. It is considered that this result has to do with several factors like the size of facilities, operation expenses, operation forms, the disposition of professional human resources, and philosophy and management policy of the owners. As far as generalization is concerned, however, it needs to be noted here that the sample size for this study is not statistically big enough to generalize the results. Conclusion: Having Developed a QMI for small-scale nursing home with 7 dimensions, 39 components and 148 indexes, this study is expected to be used in developing more elaborated quality evaluation tools for nursing homes, and also function as a practical guide of quality management for those who are opening and managing nursing homes. I hope this quality index could lead to further development of a standardized quality management index, and eventually contribute to quality improvement of nursing homes.

The concept of 'Cleaner Production(CP)' and various activities aiming at promoting CP are investigated along with the applicabilities of CP to marine environment. Although the conventional approaches dealing with the marine pollutions can be absorbed in CP, the whole activities of Production and conservation in the ocean must be projected into a new Paradigm, 'Sustainable Development.' Renewable energy is the first key to a complete CP and the ocean can provide us with the clew. In order to introduce CP system more effectively to marine environment opinion collection, environment monitoring, problem identification, resolution proposition, state-of-the-art evaluation, policy development, communication, education and public information are to be Planned and followed up systematically KOSMEE is believed to be a good structure to stand at the center of the upcoming CP activities in the ocean.

The government has promoted the local fishing port construction project since 1972 for conquest of the crisis of the fishing village by withering of a fishery, the improvement in fishermen's living environment and quality of life, and promotion of fisheries. In order to estimate the local fishing port construction project objective and synthetically, and to grope for the method proposal of system establishment of the project, the monitoring survey was carried out. The monitoring survey was classified into the program and the performance monitoring. The program monitoring was carried out in order to investigate the project fit for the inhabitants of a fishing village. The performance monitoring was carried out in order to investigate the development latent powers, fishery latent powers, tourism latent powers of a fishing village, rural settlement conditions, etc. using various statistical materials. Since investigating the measured value before executing a policy was not completed, the project effect was compared with the measured value of other areas. According to the local fishing port construction project, the development latent powers, fishery latent powers, and tourism latent powers of the fishing village where the project was undertaken improved greatly, and income of the fishing village increased greatly. As a result of comparing project fit in order to evaluate the project, the project fit of the local fishing port construction project area was higher than the non-project area. Desirable method proposal of monitoring survey was established and the method for raising the efficiency of monitoring survey was extracted.

Objective : From an analysis of a community outbreak of measles in Youngju, Gyeongbuk, in March 2000, the authors evaluated the effectiveness of the measles vaccination and its determinants to Provide an epidemiologic basis for the establishment of a vaccination policy. Methods : Information was collected regarding the vaccinations from the health records of four primary schools and through a questionnaire surrey of the parents of students in two middle and two high schools (N=4638). Measles cases were surveyed from the patient list of each school and from case reports in the public health center. The attack rate and vaccine effectiveness of measles was evaluated by school; grade; frequency, region, and institution of vaccination. Results : The attack rate cf measles, 6.3% among the total subjects, was higher in middle school students (15.8%) than in primary (2.0%, p<0.05) and high school students (8.9%, p<0.05). The attack rate of the unvaccinated group was 4.6-fold higher than the vaccinated group in primary schools (p<0.05). Vaccine effectiveness was 83.2% among lower graders of primary schools, 34.0% among higher graders of primary schools,26.1% in middle schools, and -7.0% in high schools. In multiple logistic regression analysis, grade in school (odds ratio, 0.77; 95% CI=0.67-0.87) and frequency of vaccination (odds ratio, 0.57: 95% CI=0.37-0.58) were significant predictors of the outcome. Conclusions : We concluded that the explosive outbreak of measles in this area resulted from both inadequate vaccination coverage and secondary failure of vaccination. There was no evidence of any effect of the cold chain system on the vaccine failure.

Recently in the field of IT, cloud computing technology has been deployed rapidly in the current society because of its flexibility, efficiency and cost savings features. However, cloud computing system has a big problem of vulnerability in security. In order to solve the vulnerability of cloud computing systems security in this study, impact types of virtual machine about the vulnerability were determined and the priorities were determined according to the risk evaluation of virtual machine's vulnerability. For analyzing the vulnerability, risk measurement standards about the vulnerability were defined based on CVSS2.0, which is an open frame work; and the risk measurement was systematized by scoring for relevant vulnerabilities. Vulnerability risk standards are considered to suggest fundamental characteristics of vulnerability and to provide the degree of risks and consequently to be applicable to technical guides to minimize the vulnerability. Additionally, suggested risk standard of vulnerability is meaningful as the study content itself and could be used in technology policy project which is to be conducted in the future.

Stow net fishery is one of the fishery with high fishing work accidents in southwestern sea of Korea. We conducted to serve as basic data for improving the healthy and safe working environment of fisher using risk assessment process (ISO45001) with fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) from 2016 to 2018. The average occurrence rate of victim in this fishery was 9.04%, 16.7 times more than such rate in all industries. In addition, the average fatality rate was found to have a very serious level management to 31.06‱, 27.7 times more than such rate in all industries. The safety hazards of stow net fishery was more likely to occur by other general industrial groups, with more severe consequences after the accident. According to 4M analysis, 58.6% of all accidents were caused by human factors, 24.0% by environmental factors, 16.0% by mechanical factors, and 1.5% by managerial factors, respectively. The occurrence frequency by accident type was the highest in 187 cases (32.2%) for struck by object, 158 cases (27.2%) for slipping, and 94 cases (16.2%) for being in contact with machinery. Severity is the highest for others such as diseases etc., in the order of being struck by object, being in contact with machinery, falling from above slipping, collapsing, bumping, and burning. Being struck by object, being in contact with machinery, and slipping are high-risk groups, falling from above others, bumping, and burning are medium-risk groups based on the risk assessment using the occurrence frequency and severity of accident. The obtained results are expected to contribute to the safe operation environment subsidy for fishing crews on the stow net fishing vessel.
