University ranking models, though they consider multiple indicators to evaluate universities, determine the overall score of each university based on their own normalization and aggregation methods. Thus, the rankings provided by such models primarily depend on actual scores of evaluation indicators, but they are also significantly affected by the normalization and aggregation methods. We examine the normalization methods of four university ranking models used in South Korea, China, and United Kingdom. We discuss a possible unintended consequence of these methods, i.e., some universities who want to improve their rankings may focus on unnecessary indicators, contrary to the evaluator's intension, due to the normalization methods. We suggest a new normalization method based on the statistical characteristics of the distribution of each evaluation indicator so that the new method can motivate the universities to move into the desirable directions intended by the evaluator.

The 37 indicators for performance evaluation of public sewage management agencies are divided into four major categories (agency manpower management ability, wastewater treatment plant operation and management, sludge and water reuse, service quality) in the first stage, and the necessity and score acquisition for the detailed indicators by each major category in the second stages. Priority was investigated through the Analytic Hierarchy Process (AHP) analysis technique for ease and relevance of company efforts. Also, based on the results of this analysis, integrated type weighting and relative importance were analyzed. As a result of the analysis, the weight and relative importance of the first stage classification were in the order of wastewater treatment plant operation and maintenance, operation agency manpower management ability, sludge and water reuse, and service quality. As a result of analyzing the weights and priorities of the detailed performance indicators in the second stage, it was found that operator's career years, the percentage of certification holding rate in operators, compliance with the effluent water quality standards, training times for operators, and efforts to manage hazardous chemicals were important. Some of the indicators of operation agency performance evaluation may include indicators in which the performance of the company's efforts is underestimated or overestimated. In order to improve this, it is necessary to give weights in consideration of the necessity of the indicator, the relevance of the company's efforts, and the ease of obtaining scores.

Perceived air quality (PAQ) is defined as evaluation of indoor air satisfaction and comfortable sensory by occupants. However, there are differences between criteria of indoor pollutants and lowest sensory thresholds. In this study, we compared indoor PAQ by questionnaire with measured benzene, toluene and nitrogen dioxide ($NO_2$) concentrations in home indoors. The $NO_2$ concentration was the highest in Seoul, while benzene and toluene were the highest in Asan. Average PAQ score in winter was higher than that in summer. Significant correlations between PAQs of home indoor air pollution and measured pollutant concentrations were not shown and correlation coefficients (r) ranged between -0.453

Objectives: This study was conducted to assess environmental health status on a local scale using environmental health-related indicators. It demonstrated the possibility of using a structural equation model, a methodological approach to provide synthesized information. Methods: Eighteen indicators were selected from official statistical data published by local governments. Each environmental health-related indicator was classified according to the PSR (pressure-state-response) model. Aggregation methods were performed using principal component analysis and fuzzy sets. Results: The five principal components were classified through principal component analysis (PCA) and obtained eigenvalues >1.0 from the initial 18 indicators. The aggregated index was obtained by condensing the original information into two broad and simple categories through fuzzy sets. Conclusion: This could be useful in that the aggregation procedure may provide a basis for establishing environmental health policies and a decision-making process. However, the availability and quality of indicators, assessment of aggregation method bias, choice of weighted scores for indicators, and other factors should be examined in future studies.

The purpose of this study was to measure pH, trimethylamine (TMA), and total volatile basic nitrogen (TVB-N) as indicators of freshness during largehead hairtail Trichiurus lepturus storage, and to compare these indicators with those obtained by the sensory evaluation of quality index method (QIM) sensory evaluation. Largehead hairtail samples were stored at 4℃ and evaluated every 3 days until decay. The QIM sensory evaluation indicated scores of 0, 8.9, and 20 on storage days 0, 6, and 20, respectively. By day 15, the samples were completely decayed. The pH slowly increased during the storage period, reaching a maximum of 7.4. In the day 6, TMA and TVB-N contents were 2.97 and 15.57 mg/100 g, respectively. Thus, at 4℃, the largehead hairtail starts to decay after 6 days and, after 9 days, cannot be consumed safely

PURPOSES: The purpose of this study is to develop a methodology to prioritize sidewalk construction on rural national highways. METHODS : In order to determine an appropriate prioritization for sidewalk construction, we developed a specific methodology. The proposed methodology includes three main steps: 1) Analytic Hierarchy Process (AHP) methods, 2) Subjective evaluation of relevant road agencies for the candidate sidewalks along rural national highways, and 3) Field study conduction. Each step has four phases. The primary feature of this methodology is the addition of expert consultation and survey data, as well as a field study. In addition, the method could guarantee flexibility in selection for evaluation criteria. As a result, the proposed methodology could be used as a general procedure for application to other roadway classifications when considering sidewalk construction. RESULTS: In order to demonstrate the reasonableness of the proposed methodology, a case study was performed for exactly 100 candidate sites for sidewalk construction on rural national highways. All required evaluation scores were properly produced for each candidate site. By doing so, decision-makers can determine the priority for sidewalk construction at these sites by reviewing quantitatively and qualitatively considered data. CONCLUSIONS: The results of the case study can be applied to a long-term fundamental plan for sidewalk construction on rural national highways. Furthermore, this methodology could be employed to prioritize a small-scale SOC project(e. g. bicycle or pedestrian roads).

Objectives: This study evaluated the diagnostic values of measuring the number of fungiform papillae in patients with burning mouth syndrome (BMS). Methods: Seventy participants (35 BMS patients and 35 Healthy control) participated in this study. The number of fungiform papillae (FP) was measured on the anterior part of the tongue within an area of $9mm^2$ using a digital camera. The subjects were evaluated on their yin deficiency and blood stasis conditions using the Yin-Deficiency Questionnaire (YDQ) and Blood Stasis Questionnaire (BSQ). Moreover, the severities of subjective tongue pain in the BMS patients were assessed using Visual Analog Scale. Results: There were significant differences in the number of FP and the YDQ and BSQ scores between the two groups. The number of FP and the YDQ scores in the BMS group showed statistically significant correlations with the VAS score of tongue pain. In the bivariate logistic regression analysis, the factor that most strongly contributed to BMS was the number of FP. The optimal cut-off value of the number of fungiform papillae was calculated as 5.5 with 71.4% sensitivity and 82.9% specificity. There was no statistically significant correlation between the number of FP and the YDQ or BSQ score. Conclusions: According to these findings, measuring the number of FP could be a valuable evaluation indicator of BMS.

The purpose of the study was to examine health status and mini nutritional assessment (MNA) according to self-esteem status of elderly in care hospital. The survey was carried out from $13^{th}$ to $31^{st}$ of September, 2014 in five care hospitals. Analysis was performed for 226 subjects. Evaluation criteria included demographics, clinical status, MNA, health-related quality of life (EQ-5D) and self-esteem. The SE I, SE II and SE III groups were divided by self-esteem scores. Data were analyzed one-way ANOVA, Duncan' multiple range test and Pearson's correlation using SPSS 15.0. Education level, religion, dental condition and medical endurance type were significantly different in all groups. Many elderly people were normal BMI ($20.94{\sim}21.67kg/m^2$). Self-esteem significantly increased in order of SE I, SE II and SE III. Mobility, usual activity and anxiety or depression were significantly different in all groups, and EQ-5D of SE II and SE III groups were significantly higher than that of SE I group. Comparison of MNA screening score in elderly patients was as follows : Score for food intake, psychological stress or acute disease, neuropsychological problems, pressure scores or skin ulcer, protein intake, mode of feeding, nutritional status and health status in SE I group were significantly lower than those of SE II and SE III groups. Mobility and drug intake of SE I group were significantly lower than those of SE III groups. Fruit and vegetable intake SE I group were significantly higher than those of SE II and SE III groups. MIS (Malnutrition Indicator Score) was significantly different among the SE I, SE II and SE III groups. We conclude that self-esteem score is positively correlated with protein intake, nutrition status, health status and MIS in elderly care hospital. To improve nutritional status of elderly in care hospitals, systematic nutrition management and self-esteem education program should be implemented.
