Software reliability prediction is a statistical method to put in place a timely software development practice useful for objective assessment of bidders. The current study suggests one research method that enables reliability assessment of such previous projects by studying user satisfaction and project management history. If incorporated into the existing acquisition process, the reliability assessment method will further enhance objectivity and accuracy in bidder selection process. The GQM(Goal Question Metric) paradigm was used to identify assessment metrics for bidder evaluation and questionnaires were collected from users to create user satisfaction indexes. In addition, 'weight of evidence', the most appropriate categorical method, was used to isolate attributes of each variable that may contribute to reliability assessment.

This study was carried out to construct accurate and scientific system of assessment indicators in selection of National Trust conservation areas, which was new concept of domestic environment movement and offer the raw data of new analytic method by introducing the fuzzy theory and weight for overcoming the uncertainty of ranking decision. To transform the Likert's scale granted to assessment indicators into the type of triangular fuzzy number(a, b, c), there was conversion to each minimum(a), median(b), and maximum(c) in applying membership function, and in using the center of gravity and eigenvalue, there was to decide the ranking. The rankings of converted values applied a mean importance and weight were confirmed that they were generally changed. Therefore, the ranking decision was better to accomplish objective and rational ranking decision by applying weight that was calculated in grouping of indicator than to judge the singular concept and to be useful in assessment of diverse National Trust site. In the future, because AHP, which was general method of calculating weight, was lacked, there was to understand the critical point to fix a pertinent weight, and to carry out the study applying engineering concept like fuzzy integral using $\lambda-measure$.

This study creates the LCP (Landscape Control Point) through the survey of spot sites for the quality of landscape assessment, which is based on an objective and departmentalized data base; the landscape assessment was achieved by production of weight value with the AHP (Analytic Hierarchy Process) technique, selection of requisites for the landscape assessment with the IVERSON method and visual area analysis with GIS (Geographic Information System). Futhermore, validity of the landscape assessment was verified by analysis of the correlation between physical amount and aesthetic amount. The purpose of this study is to suggest the basic essential data for landscape assessment and landscape planning by the characteristics of landscape based on verification of the suggested landscape assessment methods. The results of this study are summarized below. 1. In the adaptation of landscape assessment using GIS, the landscape assessment points of LCP 18, 17 and 16, which have more visible elements such as hill area, mountain area, and forest and farm land, were indicated to be higher than the others. In contrast, the landscape assessment points of LCP 13, 6 and 10, which have less visible elements, were relatively lower than the others. 2. In the visible preference measuring method, LCP 4, 14, and 16 showed high points of landscape assessment with 3.46, 3.4, and 3.18 each. With the more natural environments such as hill area, mountain area, and forest and farm land, higher results were shown. In contrast, LCP 7, 1, and 9 showed low points of landscape assessment with 2.24, 2.36, and 2.53 each. 3. In this study, a coefficient of 0.746 was gained by the analysis of correlation between the points of landscape assessment method and the points of visual preference from a slide show. This has 99 percent of probability in statistical data. 4. In conclusion, with the demonstration of the correlation between the landscape assessment method based on the AHP technique and the aesthetic amount (preference proportion), the practical use of landscape assessment can be demonstrated by the suggested landscape assessment method.

Purpose: The incidence of chronic diseases is increasing and the age of onset is decreasing in South Korea. Healthy eating habits to prevent chronic diseases are established in adolescence. This study verified the identified factors and dynamics that affect diet self-assessment for sustainable adolescent health and the prevention of chronic diseases. Methods: Data were collected from 492 middle and high school students in South Korea from June to July 2018, and the participants answered a questionnaire on dietary safety management competency for sustainable health. Results: The healthy dietary self-assessment scores of overweight/obese adolescents and adolescents who perceived their health as normal were significantly lower than those of other groups. Factor analysis verified the validity of the items that comprised each study area before a multiple regression analysis was used to investigate the factors affecting healthy dietary self-assessment. Sweet and salty diets, anxiety, food and nutrition knowledge, weight management knowledge, stress management, exercise, basic eating habits, and healthy eating habits significantly affected healthy dietary assessment among adolescents. A higher perception of one's health indicated a higher healthy dietary self-assessment, dietary safety knowledge, and health management practice scores (p < 0.01). Factors like healthy dietary self-assessment, food and nutrition knowledge, and weight management knowledge appear to have a significant correlation with other identified factors, except overeating. The adolescents' awareness, knowledge, and dietary safety practices influenced healthy dietary self-assessment, which can prevent chronic diseases and achieve sustainable health. Conclusion: This study illustrated how the adolescents' awareness, knowledge, and practices of dietary safety influenced their healthy diet self-assessment. The results indicate that diet-based health management competency education relative to the adolescents' self-perception and weight levels should be implemented.

The aim of this study was to examine whether administration of glutamine are able to prevent the methotrexate induced gut barrier damage, bacterial translocation, and weight changes. The animals with glutamine were fed with L-glutamine (1.2 and 2.4 mg/kg/day) for 7 days before methotrexate administration (20 mg/kg orally). 48 hour after methotrexate administration, intestinal permeability were measured for an assessment of the gut barrier dysfunction. Also, enteric aerobic bacterial counts, number of gram-negatives in mesenteric lymph node (MLN), liver spleen, kidney and heart were measured for an assessment of the enteric bacterial number and bacterial translocation. Amounts of food intake, body weight changes and organ weight changes of liver spleen, kidney and heart were measured. Methotrexate administration caused body and liver weight loss regardless amounts of food intakes. Methotrexate induced increasing intestinal permeability, enteric bacterial undergrowth and bacterial translocation to MLN, liver and spleen, but not kidney and heart. The supplements with glutamine reduced the intestinal permeability bacterial translocation, and not influences enteric bacterial number, and body and liver weight changes. This study suggested that glutamine might effectively reduce methotrexate induced intestinal damage and bacterial translocation, but not influence body and organ weight loss.

The purpose of this study was to determine the incidence of malnutrition among patients on admission to hospital, to monitor changes in their nutritional status during hospitalization, and to determine the factors which might affect changes in nutritional status. The subjects for the study were patients who were admitted to general medicine for more than one week. Patients suffering from cardiovascular. renal disease, or dehydration were excluded. Nutritional assessment of the patients was performed on admission and nutritional status was reassessed one week and two weeks after admission. The nutritional assessment tool consisted of subjective history taking and anthropometric measurements. Biochemical measurements were performed only on admission. For anthropometric assessment : patients' body weight, subcutaneous skinfolds thickness, % of body fat, body mass index, and lean body mass were measured using caliper or Bio impedance Analyzer. Factors which might influence current nutritional status, like dietary intake, anorexia, nausea, vomiting, diarrhea, sleep disturbance, and number of days of NPO for diagnostic examinations were analyzed. The results are as follows : 1. Of the 59 patients who were studied, 61% were male and 39% female. The nutritional status of all of the 59 subjects was reassessed one week after admission, but it was only done for 22 subjects at two weeks. 2. The anthropometric measurements. including weight body mass index, lean body mass, body fat. and skin fold thickness. were all significantly decreased at one week after admission compared to the values at admission. On the other hand, two weeks after admission, only body weight and abdominal skinfolds thickness were decreased. 3. The subjects reported anorexia for an average of two days, sleep disturbance for two days, and no food intake due to diagnostic test for one day. In the second week of hospitalization, almost none of the patients complained of gastrointestinal symptoms or sleep disturbance except anorexia. Food consumption which was measured based on rice intake was 60% of the food served during the first week of hospitalization, and 66% during the second week of hospitalization. 4. There was no correlation between the subjective nutritional assessment and anthropometric assessment. 5. There was no statistical significance in anthropometric measurements among the patients with various diseases whereas sleep disturbance and no food intake due to various diagnostic test was prominent in patients with gastrointestinal diseases.
