Investigations of distribution status and extinction threat evaluation of the Korean endemic species, Iksookimia yongdokensis were undertaken from 2017 to 2018. Among the 22 streams and 97 sampling sites investigated during the study period, samples of I. yongdokensis were collected from 9 streams at 37 sites (from Daejongcheon Stream of Gyeongju-si to Songcheon Stream of Yeongdeok-gun). The appearance of I. yongdokensis was relatively common in streams such as Hyeongsangang River (15 stations), Yeongdeok Oshipcheon Stream (4 stations), Gokgangcheon Stream (4 stations), Chuksancheon Stream (3 stations) and Daejongcheon Stream (3 stations). The main habitat of I. yongdokensis was in pools on flat-land in streams of clean water with slow velocity, and with pebble, gravel and sand bottoms. Previous records of the appearance of I. yongdokensis, indicate they were first seen at seven stations including Jangsacheon Stream, but they were not present in Songcheon Stream. Compared to our results there is evidence as noted for a 38.9% reduction in occupancy within 3 generations (10.5 years), and a decline inhabitat quality. Therefore, I. yongdokensis is now considered vulnerable (VU A2ace) based on the IUCN Red List categories and criteria. The main reasons for the decline were assumed to be dry weathering in the river, the introduction and diffusion of exotic fish species Micropterus salmoides, and river refurbishment project.

To evaluate the storage characteristics of Korean soups for the utilization of the Ready-Prepared Foodservice System, Yukkaejang(spicy beef and vegetable soup), Sagol-woogeojitang (bone soup with young cabbage), Kalbitang(beef short-ribs soup) and Seolleongtang(beef and bone soup) were prepared and their physico-chemical characteristics were investigated according to storage time and temperature$(4^{\circ}\;to\;20^{\circ}C)$ through analysis of pH, TBA values, Hunter color values, microbial counts, and sensory evaluation. No significant difference in pH was shown among the 4 kinds of soup while TBA values were significantly increased with storage time and temperature. Hunter color values(L, a and b values) of the Korean soups were significantly increased except Yukkaejang. In the sensory evaluation, appearance, color, flavor, taste, texture and overall acceptability of the soups decreased significantly with increasing storage time and temperature. Through correlation analysis between quality factors of treatments stored at $4^{\circ}$, the overall acceptability in Yukkaejang and Seolleongtang showed significant positive correlation with appearance, color, flavor and texture. The evaluated shelf-life of all four Korean soups was within 3 days at $10^{\circ}$, suggesting that Korean soups are applicable to ready-prepared foodservice system.

The distribution aspect and extinction threat evaluation of the endangered species, Rhodeus pseudosericeus were investigated from 2012 to 2017 in Korea for the subject of this study. The number of appearance sites in the past literature of available and identified R. pseudosericeus was 26. During the study period, the samples of R. pseudosericeus were collected in 44 sites (Hangang River 35 sites, Sapgyocheon Stream 4 sites, Daecheoncheon Stream 5 sites) among the noted 214 sampling stations investigated. Among these, the newly appearance streams were Ilricheon Stream, Samsancheon Stream, Bangyecheon Stream and Hanpocheon Stream in the Hangang River. In addition, the habitats and populations in the upper Seomgang River (Hoengseong Dam), lower Heukcheon Stream, Muhancheon Stream and Daecheoncheon Stream decreased due to dam construction, river work, water pollution, and the spread of the exotic species Micropterus salmoides. The main habitat of R. pseudosericeus was the middle-upper stream of clean water with slow water velocity, sand-pebble bottoms and lots of aquatic plants. Given this evidence as noted for the 30.2% reduction in occupancy within 10 years, due to the qualitative decline of habitat, the overfishing risk of ornamental fish and the spread of M. salmoides, in this case R. pseudosericeus is considered to be Vulnerable (VU A2cde) based on the IUCN Red List categories and criteria.

The purpose of this study was to suggest the skirt grading rule for different somatotypes. For this study 9 subjects were classified three types according to the shape of front hips such as diamond, standard, heart. Skirts pattern were made by Moonwha grading method for traditional grading rule. For each somatotypes, skirt pattern were graded by new grading rule. The sensory evaluations were practiced for appearance and function. At the result, comparing between the new grading rule and traditional grading rule, new grading rule was fitter than the traditional grading rule. And diamond type was distinctively better than the other somatotype at sensory evaluation appearance. For pattern making of diamond type it had better use the new grading rule that was considered the characteristics of body shape.

This study compared the work environment colors and the colors of working clothes by conducting a field survey of domestic machinery manufacturers who are playing a central role in Korean industries so as to develop and evaluate working clothes based on the safety of workers and environmental harmony. For the study method, after the color-related requirements were collected through interviews and field surveys, the fabrics for working clothes were woven and the colors were selected using the requirements. The designs of working clothes were developed with an emphasis on color design. The colors of the working clothes were also analyzed in their relationship to the working environment. The evaluations were separately performed for the appearance and the colors with workers of D machinery manufacturing company. The appearance and color satisfaction, safety, psychology, and harmony with environment were evaluated on a 5-point scale by workers and their safety managers. Furthermore, pictures of the workers in their existing working clothes and the newly developed working clothes were taken with a digital camera while they were working in the field. The RGB values of the pictures were extracted using Photoshop ver. 7.01, which were converted to HVC values using Munsell Conversion ver. 4.0.1. This study found that higher satisfaction levels were shown for the newly developed working clothes compared to the existing ones. The actual measurements also showed that the newly developed had higher brightness and clearer chromatic contrast than the existing ones, indicating higher explicitness and attention for safety of workers. These types of studies can contribute to the integrated working environment plan of machinery manufacturers.

The aim of this study is to develop upper bodice pattern for obese girls aged 10~12 by using 3D virtual garment simulation system. The criteria for subjects in this study were girls who had over 1.46 of the R$\ddot{o}$hrer Index. A total of 229 schoolgirls who met these criteria were enrolled. The results of this study are as follows: First, by using 3D virtual garment simulation, new upper bodice pattern considered obese-schoolgirls was development. The basic numerical formula were as follows ; bust girth B/2+4.5, armhole depth B/4-1, waist girth W/4+0.5+dart amount, front chest width B/6+2, back width B/6+2, neck width B/12-0.5 and neck depth B/12+0.5. Second, armhole darts were added to compensate the loose amount of front armhole and dart manipulation was used to ensure a better appearance on armhole in the design. The dart side line was modified concavely to help cover the protruding stomach. Curved lines on the armhole were significantly relieved using dart manipulation and the darts side line was modified concavely to reduce the tightness around the front waist darts. Third, according to the results of the new upper bodice pattern's appearance evaluation, it estimated more highly than existing pattern in silhouette and ease amount, confirming that new upper bodice pattern was appropriate for the obese-schoolgirls. This study is expected to serve as one of important basic data for ensuing studies that may utilize 3D virtual garment simulation system with 2D patterns.

A scientific and systematic approach for digitally representing colours is essential for improving image quality. Therefore, there is a need for objectively analysing such approaches. Studies regarding display systems, which can reflect human visual characteristics in the digital media environment, and associated international standards at the forefront, have already caused significant impact. Colour is one of the most important factors employed for evaluating the overall image quality of displays. The proposed study focusses on colour properties which are based on the characteristics of the human peripheral vision area, with the primary objective of reproducing digital colours which can simulate human visual characteristics in the digital media environment. The proposed study aims at identifying digital colour characteristics which can vary according to the level of background lightness and the size of colour stimuli. Based on the evaluation results obtained through psychophysical experiments, a method has been proposed for determining peripheral vision characteristics which vary according to the increasing size of a colour stimulus, thereby digitally reproducing them on displays.

Identifying quality attributes with the greatest value to the residents is important if the Continuing Care Retirement Community (CCRC) is to increase the frequency of residents' dining. However, it is not known which specific attribute is relatively more important than others to evaluate foodservice. The purpose of this study is to identify the relative importance of food and service quality attributes in the evaluation of foodservice in CCRe. This study surveyed the independent living residents of three CCRCs in the Midwestern states. Respondents placed great importance on taste and flavor of food which has the highest percentage of utility range ($28.28\%$) and the second greatest on appearance of the server ($23.46\%$) . The important attributes were ultimately used to predict the most preferred choice of food-service for residents. Knowledge of the importance of the attributes would enable the foodservice managers in CCRCs to manipulate those attributes to enhance the residents' perceptions of quality and identify strategies for continuous improvement.
