This study has developed a design indicator required to promote green remodeling in school facilities. And, implemented the green remodeling pilot test on the school facilities that are planning actual remodeling. This pilot test suggested user participation design methodology such as verification of the developed design indicator, design goal setting, evaluation and adjustment of design proposal. The Green Remodeling Design Indicators were classified into 3 large categories of architectural performance, usability, and design through analysis of cases related to 'green buildings' and 'remodeling'. We have developed nine middle categories such as architectural and structural performance, facility performance, environmentally-friendly, circulation, space, amenity, harmony with surroundings, form and symbolization. In addition, 42 detailed indicators were developed for each category, including general, functional, and special indicators. For the verification of this study, two green remodeling design workshops were conducted for Gwangju J elementary school. The first design workshop presented the importance of the design indicator and set the goal of the design plan of green remodeling for project. And, the second Workshop presented the evaluation of the satisfaction with the design and the direction of future adjustment for project. The design indicator developed in this study can be utilized as a design indicator of design quality management and decision system for the school green remodeling in the future. In addition, by accumulating information on the Green Remodeling Project, it is necessary to spread green remodeling and construct a sustainable building environment.

Purpose: To evaluate the diagnostic value of the Vesikari Scoring System (VSS) as an early predictor of pathogens in children with acute gastroenteritis (AG). Methods: In this retrospective study, the VSS score, absolute neutrophil count (ANC), and C-reactive protein (CRP) levels were analyzed in 107 hospitalized children with AG, aged 6 months to 17 years. Patients were divided into nonspecific, viral, and bacterial groups according to the pathogens detected using a multiplex polymerase chain reaction (PCR) test. Results: Patients in the bacterial group had significantly higher CRP values and VSS scores compared to those in the viral group and significantly higher VSS scores compared to those in the nonspecific group (P<0.05). Patients in the viral group had significantly higher VSS scores than those in the nonspecific group (P<0.05). Logistic regression analysis revealed that VSS was the most effective diagnostic tool for predicting the type of pathogen (P<0.05). The area under the receiver operating characteristics curve of VSS was significantly greater than that for ANC and CRP (P<0.05). At a cutoff point of 10 in the VSS, an acceptable diagnostic accuracy could be achieved for distinguishing between bacterial and viral pathogens in AG. Conclusion: VSS can be considered a useful and reliable infectious marker for pediatric gastroenteritis. VSS may be a good early predictor of the type of pathogen, enabling development of a treatment plan before results from a stool culture or PCR test are available.

Regional differences between large cities and rural areas are observed in the Korean National Health and Nutrition Examination Survey (KNHANES). This present study was conducted to evaluate the effect of dietary factors on hypertension risk in Korean populations, especially residents of the Chungcheong province which was not in metropolitan area, using KNHANES III. A total of 544 adults aged ${\geq}$ 19 years were placed into either the normotensive or the hypertensive group. Subject characteristics, BMI, blood pressure, and nutrient intakes were compared between the two groups using a chi-square test and t-test. We estimated odds ratios (ORs) using multiple logistic regression, adjusted for energy intake and selected covariates. There were significant differences in age, education level, alcohol consumption, and BMI between the normotensive and hypertensive groups. We found decreased ORs for the medium versus lowest tertile of calcium intake (multivariate OR=0.43, 95% CI: 0.21-0.88), for the highest versus lowest tertile of calcium intake (multivariate OR=0.43, 95% CI: 0.20-0.90) with significant trends in risk (P=0.040), and for the medium versus lowest tertile of potassium intake (multivariate OR=0.43, 95% CI: 0.20-0.89). Subjects with the highest sodium/calcium ratio had a 2.10-fold greater risk of hypertension compared to the subject with the lowest, with significant trends in risk (P=0.002). Adequate calcium and potassium intake should be encouraged and regional differences should be considered in making a healthy plan for hypertension management.

The purpose of this study was to examine whether a gratitude training program for preservice dental hygienists affects their gratitude disposition, self-esteem, and happiness. Dental hygiene students were recruited from a college in D and administered a pretest. The 76 selected participants were primarily those who had never written a gratitude journal. Participants were then randomly divided into an experimental group and a control group. Three participants failed to complete the program, leaving 73 subjects in the final analysis. Data were analyzed using the ${\chi}^2$ test, independent sample t-test, and analysis of covariance. The mean gratitude disposition score improved from $31.11{\pm}5.55$ in the pretest to $34.41{\pm}4.38$ in the posttest in the experimental group and from $31.44{\pm}4.41$ to $32.06{\pm}4.63$ in the control group. The mean self-esteem score improved from $31.22{\pm}4.03$ to $33.16{\pm}3.44$ in the experimental group and from $30.53{\pm}4.42$ to $30.97{\pm}3.80$ in the control group. The mean happiness score improved from $19.54{\pm}2.64$ to $21.78{\pm}2.43$ in the experimental group and from $19.64{\pm}3.32$ to $20.08{\pm}2.91$ in the control group. All of the participants improved their gratitude disposition, self-esteem, and happiness scores while participating in the gratitude training program, and it is expected that if such positive emotions can be sustained, they will naturally acquire the basic requirements of dental hygienists and build a better vocational consciousness and a higher sense of duty, as well as have a further positive effect on the quality of dental medical service. Further studies should be conducted to propose a concrete plan to expand and operate this gratitude training program more effectively.
