This research was to develop Taekwondo trunk protector(Hogu) and head protector's sizing systems corresponding the regulations by World Taekwondo Association. These sizing systems were established using 2003-2004 Size Korea anthropometric data. The result can be summarized as follows: According to the analysis of correlation, most measurements had high relationship with weight for Hogu and head girth for head protector. Six sizes(47, 54, 59, 64, 70, 76) for Hogu and 4 sizes(52, 54, 56, 60) for head protector were suggested in this study. Hogu sizes indicate body weights and head protector sizes express head girth measurements. By the comparison between current Hogu sizes and new sizes, the smaller sizes of new Hogu were bigger than current sizes in bust girth, back fastening length, shoulder length. On the other hand, the bigger sizes of new Hogu were larger than current sizes in bust girth, back fastening length, shoulder length. In addition, new Hogu's lengths were shorter than current Hogu in all sizes. The lengths of Neck to collar bone in new Hogu sizes were longer than current Hogu. In case of the head protector, there were no measurements besides outer circumference of helmet in recognized specifications of WTF. Therefore some referable measurements such as head girth, head length, bitragion arc, sagital arc were suggested in new size specification. When helmet sizes were suggested, the thickness of the NBR foam also were considered.

The development of foundation garment pattern on the typical adult women's body was carried out. By means of the flatted body surface shell, the foundation garment pattern was developed. And its fitting test also performed. The results of this study can be summarized as follows; 1. The investigated Foundation basic pattern was made by the allowing the maximum bust size without any surplus since it was based on the tight-fitted model drawing technique. The investigated the completed pattern was designed in three parts of front and back body, including bust. 2. The result showed by overlapping the torso basic pattern foundation and body surface development selected from body almost the same except for the shift of dart position. 3. The result by overlapping basic pattern 3 existing basic patterns. On the basis of top-bust line showed that the setting up the volume of dart of bust and its waist affect the appearance of model. Especially, it was found that the above result was related to the bust and under bust line. 4. The result of the wearing test of 3 existing basic patterns and basic pattern of this study revealed that the mean values of whole items were higher than average in type P and type E. The fitting & position of under-bust line and extent of wrapping bust showed the high points in the current study and type of P. The result of evaluating the whole appearance in three points(front, side, back) showed different according to the every basic foundation garment pattern.

We have developed a software package for the analysis of electric field distribution in human body. It includes the graphical finite element mesh generator, linear system of equations solver using sparse matrix and vector technique, and post-processor for the display of the results. This software package can be used in various research areas of biomedical engineering where we inject current or apply voltage to human body. The software package was developed on Macintosh II computer and the size of the model is only limited by the main memory.

Optimization of the protocorm-like body (PLB) formation of Phalaenopsis and Dendrobium hybrids was performed by determining the effects of plant growth regulators (PGRs) and different parts and division sizes of the PLB. For both genera, the base part was the best for the proliferation of PLBs, yielding the highest number of PLBs on a PGR-free medium for Phalaenopsis and medium containing $0.1{\mu}M$ NAA and $10.0{\mu}M$ BAP for Dendrobium. As regards the division size, four-division sections resulted in a higher PLB formation efficiency for Phalaenopsis, while two-division sections produced a higher PLB formation efficiency for Dendrobium. It is expected that these findings will be applicable to efficient PLB formation of other Phalaenopsis and Dendrobium orchids.

Protective clothing for riot policewomen is worn by policewomen to protect their body at suppressing a riot. Plastic guards of Nylon 66 material are attached to the base of E.V.A. Foam material. Protective clothing for riot policewomen consists of a jacket, guards for arms and legs, upper arm braces, and thigh pads. This study was aimed to develop the base pattern of the jacket to protect the torso and to improve the body suitability and the adaptability to movements of protective clothing for riot policewomen. Since current protective clothing worn by riot policewomen is manufactured with the same design of protective clothing for riot policemen, the body suitability and the adaptability to movements are not very satisfactory for policewomen who has different body structure than from riot policemen. Therefore, the purpose of this study is to reflect the body size and characteristics of riot policewomen and develop the base pattern of protective clothing with better body suitability and adaptability to movements. In this respect, amount and place of dots on the jacket were differently designed, made and evaluated by fitting test. The base with the best evaluation was selected as the final experiment clothing to demonstrate its superiority compared with the existing protective clothing.

Background: Geladas (Theropithecus gelada), endemic to Ethiopia, are distributed closely related to the escarpments and gorge systems of the country, and large populations are found in the Simien Mountain National Park. This study was conducted in Eastern Tigray, Northern Ethiopia, from February 2018 to August 2019 in order to determine population size and composition of geladas. Total count method was used to estimate the population structure of geladas. Observations of the group of geladas based on body size and morphological characteristics were used to classify age and sex categories of the population. SPSS Version 20 was used to analyze the data. Chi-square test was used to compare sex ratio of geladas and population size among the counting sites between wet and dry seasons. Results: A total of 112 and 99 individual of geladas were counted during wet and dry seasons, respectively. Of the average gelada population recorded in this study, 11.4% were adult males, 30.3% were adult females, 12.8% were sub-adult males, 25.6% were sub-adult females, and 19.9% were unidentified juveniles. However, there was no statistically significant difference among the various age and sex groups of geladas counted during wet and dry season (χ² = 2.6, DF = 4, P > 0.05). Variations of group size along seasons were observed in this study. Sex ratio of adult male to adult female was 1:2.6 and 1:2.7 during the dry and wet seasons, respectively. Conclusion: Very small gelada population size was recorded in the current study. An average of 105.5 geladas was recorded during the study period. As this is the first report of gelada population in escarpments of Eastern Tigray, population trend of the geladas cannot decide based on the current study.

선망 어업은 우리나라 연안 어업에 있어서 매우 중요하며, 그 주 대상 어종은 고등어류이고 주 어장은 쓰시마 난류역이다. 이들의 어장과 해황과의 관계를 조사하기 위하여 크기별 고등어 어획량의 평균 분포(1974~1982)를 파악하고, 주요 어장인 제주도 동쪽 및 서쪽에 대한 해양 관측을 1983년 7월과 10월에 각각 실시하였다. 그 결과, 고등어류의 주요 어장은 역시 한국 남해의 쓰시마 난류역이었으며, 주어기는 5월과 9~10월이었다. 또 고등어류의 어획량은 체장 27~31cm(2~3세)인 소.중 고등어가 약 90%를 차지하였으나, 2~3월에는 체장 22cm (1세)의 콩 고등어가 약 40~70% 이었다. 계절적인 어장의 위치를 쓰시마 난류의 지표수인 15$^{\circ}C$ 등온선의 북상 또는 남하 위치로 알 수 있었다. 제주도 동쪽 및 서쪽의 주어장은 쓰시마 난류수와 한국 연안수 혹은 황해 저층 냉수와의 사이에 형성되는 조경역 이었다. 또 이들 어장의 투명도 및 수색, 태양광의 투과율의 분포는 수온과 염분의 분포 및 플랑크톤 습증량의 분포와 비슷하였다.
