River-water quality has been greatly improved during past several decades with the extraordinary expansion for the wastewater treatment capacities by the government. Research aims to select the priority restoration streams based on the chronicle data for tributaries in Geumgang watershed as the main stream area in the Chungchungnamdo province. The quality of BOD, phosphorus and percent of sewered population on 15 branch streams were compared by the grouping methods. The results of group D streams by category I that exceed 3.0 mg/L for BOD and 0.1 mg/L for phosphorus were Seuksung, Ganggyung and Bangchuk stream. The results of group D streams by category II that exceed 3.0 mg/L for BOD and less than 63.5 % of average percent of sewered population were Ganggyung, Gilsan, Bangchuk and Seuksung stream. The final results of selected streams drawn by the chronicle data which exceeded the standard quality and lower than the average percent of sewered population were Seoksung, Gangeyung and Bangchuk stream. The pollution of rivers in the down streams were more serious than in the upper streams. Their watersheds have to be improved river water quality, especially to extend sewer systems as well as wastewater treatment facilities.

This study analyzed the temporal and spatial characteristics of water quality for five hydropower dam reservoirs in South Korea. Water temperature, pH, dissolved oxygen, and chlorophyll-a (Chl-a) showed high fluctuations in summer and autumn at all reservoirs, indicating the existence of seasonal effects. At all five reservoirs, the concentrations of suspended solids (SS) and total nitrogen (TN) fell under the "slightly bad" category and those of total organic carbon (TOC) fell under the "slightly good" category or higher, according to "the standard for living environment of lake water quality." Variations in the concentration ranges and degrees of change in SS, TN, and TOC among reservoirs were observed, indicating the influences of rainfall, surrounding environments, and seasonal changes. Daecheong and Namgang Dam showed high Chl-a concentrations in summer, indicating that the metabolism of microbial communities, such as algae, was active.

Chungcheongnam-do has been measuring the flow rate and water quality of streams in the province once a month since 2011 in order to water environment policies. Based on the results, after evaluating the coefficient of variation and the tendency of the water quality trend by using the Mann-Kendall test and Sen's Slope for each stream, the streams subject to priority introduction of Total Pollution Load Management at Tributaries were selected through the Stream Grouping Method. The water quality trend analysis results for 125 streams using the Mann-Kendall test and Sen's Slope were evaluated as streams showing a tendency of deteriorating water quality Biochemical oxygen demand (BOD): 13 streams, Total Phosphorus (T-P): 16 streams). Streams with deteriorating water quality were classified into A-D groups using the Stream Grouping Method. Group A, which has a high flow rate and high water quality, is a stream that requires priority management, and was selected as a stream for introduction of Total Pollution Load Management at Tributaries. There are 7 streams that need to be introduced into the BOD category, and there are 7 streams that need to be introduced into the T-P category. In this study, based on flow and water quality monitoring data accumulated over a long period of time (2011-2022), statistical techniques are used to select watersheds in which water quality is deteriorating. Accordingly, it is expected that it will be useful in establishing a water quality improvement plan in the future.

The purposes of this study were to investigate preference and images of Korean traditional motifs, and to identify the relationship between them. The subjects consisted of 369 male and 356 female undergraduate students. The experimental materials used in this study were 48 stimuli and a questionnaire composed of 7-point semantic differential scales of 26 adjectives. Twelve motifs selected from 3 groups of Korean motifs were used as pattern design stimuli. Twelve repeated patterns were constructed from them to be applied on a CAD-simulated dress. The data were analyzed by ANOVA, Duncan's multiple range test, and regression. The major findings were as follows : 1. Category, composition type, and application object had a significant effect on the preference. Interpretation type has no significant effects on the preference independently, but it had interaction effects when combined with composition type, and category. Especially the composition type had a greater effect than the other variables on the preference. Cloud motif and its abstract and decorative type were found to be more related to the preference than the other category and interpretation type. On the basis of the analysis results, image charts and preference charts were developed. By combining information from the image chart and preference chart, motifs and images preferred by consumers may be selected and developed into new valuable designs. 2. The preference was affected mainly by 'quality'image followed by 'simplicity', 'interest', and 'modernity'image. The preference on pattern design was affected by 'quality', 'simplicity', 'interest', and 'interest', 'simplicity', and 'modernity'image in the order. The relationship between the preference and sensibility images has been represented by equations.

The purpose of this study was to use the Kano model to compare and analyze the educational service quality attributes of domestic and foreign culinary arts schools. For this purpose, a questionnaire-based survey was completed by 312 students who were studying in domestic and foreign culinary schools. The results of the study indicated that 23 of the total 25 attributes were significantly different between domestic and foreign culinary arts school.; the "minium 4 hour-kitchen class" and "mandatory internship program" were classified into "indifferent quality" for domestic schools and a "must-be quality" for foreign schools; "well-organized internship guidebook", "kitchen class limited to 20 students", "introducing the latest food or restaurant trends", "library with the latest publications related to major", "objective instructor's evaluation", "detailed instructor's evaluation", "instructor's field experience", and "decent communication skills on the part of the instructor" attributes were classified into "attractive quality" for domestic schools and "must-be quality" for foreign schools; and "kitchen classes operated by block system", and "foreign instructors for each ethnic cuisine" attributes were classified into "indifferent" and "attractive quality" for both domestic and foreign schools, respectively. Also, according to the Better and Worse quotient designed by Timko, there were more attributes for domestic school than for foreign school that scored over 0.5 in the Better category and fewer attributes for domestic than the foreign scored over 0.5 in the Worse category. The results also indicate that, students in foreign schools receive an educational service of better quality than students in a domestic school. As a result, this research suggests significant implications to develop culinary educational services.

Purpose : This study aimed to evaluate the relationship between self-esteem and quality of life according to the job satisfaction occupational therapists, and to contribute to wards providing positive directions to improve the quality of work performed by the occupational therapists and their quality of life. Methods : A total of 118 occupational therapists working on site were surveyed during the study period, from April 8, 2019, to May 10, 2019. The collected data were expressed as frequency and percentage and were subjected to Pearson's correlation analysis and multiple regression analysis using SPSS (Windows ver. 20.0). Results : First, the occupational therapists' job satisfaction job satisfaction averaged 3.20 points, with the highest chance of promotion among the lower factors, followed by the conservative level, the work itself, and interpersonal relationships. Second, the analysis of job satisfaction according to the general characteristics of the subjects revealed statistically significant differences with respect to age, marital status, highest education level, service period, average pay, and average working hours of the occupational therapists. Third, the sub-category of job satisfaction and self-respect showed the most positive correlation with the person-in-charge, and the sub-category of job satisfaction and the quality of life showed the most positive correlation with interpersonal relationships. This shows that higher job satisfaction increases the self-esteem and quality of life. Fourth, the significant task satisfaction sub-factor predictor for the self-esteem of the occupational therapists was the job itself, and the significant job satisfaction sub-factor predictor for quality of life was interpersonal relationships. Conclusion : The results of this study showed that among the sub-categories of job satisfaction of the occupational therapists, work itself and interpersonal relationships had the greatest effect on the self-esteem and quality of life of the occupational therapists.

The purpose of this study is a proposal about the flexibility of the performance category to revitalize the "Housing Performance Grading Indication System". This system consists of 5 main performance parts, 14 performance categories and 20 detailed performance lists. 5 main performance parts are Noise and Acoustics(Light-weight impact sound control, heavy-weight impact sound control, sound control of toilet, sound control of party wall), Long-life(flexibility, remodeling & maintenance, durability), Landscape & Indoor Environment(landscape, formaldehyde control& ventilation, daylighting, thermal environment), Welfare & Barrier-free(playground and community center, welfare space, barrier-free design), Fire Safety(fire safety, safe place, fire-resisting quality). The flexibility of the performance category is conformed to Long-life housing related grading and can realize the Long-life housing in response to resident needs about the space rearrangement. Now, The flexibility of the performance category is limited to the evaluation of the private space, that is, the Skeleton evaluation. This study would suggest alternatives to improve uppermost limits through analyzing 60 examples from January 9th 2009 to October 30th 2008. The flexibility of the performance category is possible to estimate not only the Skeleton evaluation but also the Infill evaluation in response to social changes.
