The objectives of this study were to identify the roles of local government for developing community lifelong education, and to suggest desirable directions for upbringing human resource for the future in local community. The roles of local governments have become a more difficult challenge in the context of the ever increasing trends of rural population's moving toward urban areas mainly for the better education for their children. Even though there are regional differences in income level, educational environment, and budgetary constraints. local governments can play an important role in helping community people to build strong community in terms of economic development and enhancing the level of quality of life, and upbringing community leaders. Local governments' priority should be given to provide the better educational opportunities for students as well as community people through community lifelong educational programs.

Objectives: By analysing the recent trends of published papers in the Korean Journal of Health Education and Promotion, this study aims to identify and discuss some challenging issues, and to provide recommendations for quality improvement of the research papers. Methods: One hundred and sixty five papers published between 2009 and 2011 were examined and categorized according to selected standards. Results are displayed in frequencies and percentages. Results: The volume of articles published has increased by two-folds in three decades since the publication of the first issue. More than 90% of the papers were original articles. Cross-sectional research design was most frequently applied, while only 11.5 % of the articles were intervention studies. For cross-sectional research articles, limitation in generalizability of the study findings was mentioned as one of the major issues, in relation with the frequent use of convenient sampling methods and lack of theoretical evidence in inclusion of variables. Consideration of internal and external validity of the study, utilization of scientific evaluation design and mixed evaluation methods were recommended for intervention research to improve the quality of the research results. Conclusion: To serve as a key resource for evidence-based practices in health promotion, more strict scientific research criteria should be applied to the articles published in the Korean Journal of Health Education and Promotion.

Objectives : This study was conducted to evaluate the effect of fixed critical pathway with emr (electronic medical record) on the length of hospital stay, the cost and quality of care provided to gastrectomy patients in a university hospital and to develop flexible critical pathway with emr which can be used excluded or drop-out patients. Methods : Thirty-eight patients with gastrectomy were included as case group and Thirty-four patients included as control group. The comparison between control and case with using fixed critical pathway were done. To develop and to evaluate usefulness of flexible critical pathway with flexible data base, simulation was done for flexible critical pathway with drop-out patients. Result : The major results of this study were as follows: There were no significant differences in patient clinical conditions and no sign of deterioration of quality from critical pathway. The length of hospital stay was 11 days in control group, 8 days in path group(P<0.01). The total costs during the hospital stay were reduced in path group. However the cost per day was significantly increased from reduction of hospital stay(554,352 won in control, 645,669 won in path group). One hundred percentage of drop out patients(60) in the simulation of flexible critical pathway was successful. Conclusion : Computerized critical pathway reduced the length of hospital stay, total hospital costs and resource utilization without harming quality of patient care. The flexible critical pathway program can be used as one of the powerful management tools for reducing the practice variations and increasing the efficiency of care process and decreasing the workload of doctors and nurses in Korean hospital settings.

Objectives: The purpose of this pilot study was to examine the effects of a mindfulness-based Body-Mind Intervention Program using marine resources on the improvement of quality of sleep, mood symptoms, and cognitive function in Korean female emotional labor workers. Methods: Twelve female workers who experienced excess emotional labor participated at the training camp program for five days in Danghangpo-ocean park, Goseung-gun, Gyeongnam Province in South Korea. Participant sleep quality, mood symptoms, and cognitive functioning before, after, and 1.5 months later were evaluated and analyzed. Results: After participating in the marine resource program, participants reported significantly decreased sleep latency. Global sleep quality, cognitive functions (attention, flexibility, and inhibition control), and mood states, including depression, tension, anger, fatigue, were also improved. These effects were generally maintained after 1. 5 months (PSQI t = 2.63, p = 0.02 ; HAM-D t = 5.92, p < 0.001). Conclusion: A Body-Mind Intervention Program using marine resources was effective in relaxing emotion-related tension and improving cognitive function. To advance this pilot study, it is necessary to carry out further research to investigate the use of marine resources in mental health interventions.

This paper proposes an interference avoidance approach for Constraint-Based Routing (CBR) algorithm in the Multi-Protocol Label Switching (MPLS) network. The MPLS network itself has a capability of integrating among any layer-3 protocols and any layer-2 protocols of the OSI model. It is based on the label switching technology, which is fast and flexible switching technique using pre-defined Label Switching Paths (LSPs). The MPLS network is a solution for the Traffic Engineering(TE), Quality of Service (QoS), Virtual Private Network (VPN), and Constraint-Based Routing (CBR) issues. According to the MPLS CBR, routing performance requirements are capability for on-line routing, high network throughput, high network utilization, high network scalability, fast rerouting performance, low percentage of call-setup request blocking, and low calculation complexity. There are many previously proposed algorithms such as minimum hop (MH) algorithm, widest shortest path (WSP) algorithm, and minimum interference routing algorithm (MIRA). The MIRA algorithm is currently seemed to be the best solution for the MPLS routing problem in case of selecting a path with minimum interference level. It achieves lower call-setup request blocking, lower interference level, higher network utilization and higher network throughput. However, it suffers from routing calculation complexity which makes it difficult to real task implementation. In this paper, there are three objectives for routing algorithm design, which are minimizing interference levels with other source-destination node pairs, minimizing resource usage by selecting a minimum hop path first, and reducing calculation complexity. The proposed CBR algorithm is based on power factor calculation of total amount of possible path per link and the residual bandwidth in the network. A path with high power factor should be considered as minimum interference path and should be selected for path setup. With the proposed algorithm, all of the three objectives are attained and the approach of selection of a high power factor path could minimize interference level among all source-destination node pairs. The approach of selection of a shortest path from many equal power factor paths approach could minimize the usage of network resource. Then the network has higher resource reservation for future call-setup request. Moreover, the calculation of possible path per link (or interference level indicator) is run only whenever the network topology has been changed. Hence, this approach could reduce routing calculation complexity. The simulation results show that the proposed algorithm has good performance over high network utilization, low call-setup blocking percentage and low routing computation complexity.

Background : It is a primary goal for hospital personnel to improve the quality of patient care. In Korea the concept of quality assurance has been spread over the last five years. Many hospitals have implemented quality assurance programs that fit their own philosophy and needs. As a result, they are supposed to have different experiences and attitudes toward quality assurance. To investigate their diversity will be helpful to have a direction to the future and to enhance the quality assurance activities in Korean hospitals. Objectives : The aim of this study is to obtain information about hospital personnel's attitude and opinion toward quality assurance in hospitals. Methods : A questionnaire was developed which consisted of five parts; the general characteristics of respondent, the concepts of quality assurance, need for quality assurance program, current status of quality improvement activities, and participation in programs. Using the registry of Korean hospitals, 102 hospitals with more than 400 beds were selected. Questionnaires were mailed to hospital staffs of each hospital; top managers, clinical department heads, registered nurses, medical recorders, and administrators. Results : Of 2038 questionnaires sent, 877 were returned, giving response rate of 44%. Most respondents(70%) regarded quality assurance as efforts to provide patient with care in highest quality and to improve effectiveness or resource utilization. Ninety-nine percent of respondents agreed to need for quality assurance in their hospitals. There were current quality improvement programs implemented in the department of 553 respondents(62%), and most of the(85%) have participated in at least one program. Lack of motivation was pointed out as a barrier to implement the programs. Conclusion : Although most respondents have known of the concept and need for quality assurance, this study suggests that education and motivation of hospital personnel be needed to activate the quality assurance programs in hospitals.

Agricultural reservoirs in Korea have been recognized as an emerging resource for recreational and cultural activities for residents. However, most of the reservoirs are eutrophic and showing high level of contamination with nuisance algal bloom and offensive odor during the summer. For better management and restoration of the reservoirs' water quality, scientific modeling approaches could be used to diagnose the problems and evaluate the efficacy of alternative control measures. The objectives of this study were to validate the performance of a three-dimensional (3D) hydrodynamic and water quality model (Environmental Fluid Dynamics Code, EFDC) for a eutrophic agricultural reservoir and assess the effect of bypassing of the effluent from a wastewater treatment plant on the reservoir water quality. The 3D model successfully simulated the temporal variations of water temperature, DO, TOC, nitrogen and phosphorus species and Chl-a observed in 2014 and also captured their spatial heterogeneity in the reservoir. The simulation results indicated that the point source bypassing may reduce the T-N and T-P concentrations of the reservoir by 6.6 ~ 8.2 %, and 1.7 ~ 16.8 %, respectively. The bypassing, however, showed a marginal effect on the control of TOC due to the increased algal biomass associated with the increased water retention time after bypassing as well as the lower TOC level of the effluent compared to the ambient reservoir water.

The objectives of this study were to manufacture the red ginseng vinegar based on rice wine and red ginseng concentrate (RGC) using $Acetobacter$ $aceti$ and to evaluate its quality with remaining crude saponin contents and sensory score. The maximum prosapogenin (ginsenoside-Rh1, Rh2, Rg2, and Rg3) content in RGC regarding ginseng was obtained from such processes as steaming, drying, and extraction. When RGC was added into a rice wine in the range of 0-1% before acetic fermentation, pH decreased slowly during 20 days depending on RGC contents, but total acidity was not dependent on RGC contents. Compared to the crude saponin content (71.75 mg/g) of ginseng vinegar added RGC after acetic fermentation, the fermentation with RGC produced a lower crude saponin content (16.95 mg/g) in red ginseng vinegar. Sensory scores such as odor, taste, and overall preference, however, vinegar fermented with RGC were higher than those of vinegar added RGC after acetic fermentation.

The objectives of this study were to estimate leaf area index (LAI) as a function of image-derived vegetation indices, and to compare measured and estimated LAI to the results of crop model simulation. Soil moisture, crop phenology, and LAI data were obtained several times during the 2001 growing season at monitoring sites established in two central Missouri experimental fields, one planted to com (Zea mays L.) and the other planted to soybean (Glycine max L.). Hyper- and multi-spectral images at varying spatial. and spectral resolutions were acquired from both airborne and satellite platforms, and data were extracted to calculate standard vegetative indices (normalized difference vegetative index, NDVI; ratio vegetative index, RVI; and soil-adjusted vegetative index, SAVI). When comparing these three indices, regressions for measured LAI were of similar quality $(r^2$ =0.59 to 0.61 for com; $r^2$ =0.66 to 0.68 for soybean) in this single-year dataset. CERES(Crop Environment Resource Synthesis)-Maize and CROPGRO-Soybean models were calibrated to measured soil moisture and yield data and used to simulate LAI over the growing season. The CERES-Maize model over-predicted LAI at all corn monitoring sites. Simulated LAI from CROPGRO-Soybean was similar to observed and image-estimated LA! for most soybean monitoring sites. These results suggest crop growth model predictions might be improved by incorporating image-estimated LAI. Greater improvements might be expected with com than with soybean.
