To overcome the problems of classical pulmonary banding procedure, we developed a percutaneously adjustable pulmonary artery ba ding device. The banding device consists of banding portion of zig-zag shaped self-expandable stainless steel wire, shaft portion made by a polyvinyl catheter and a screw adjuster which includes a bolt and a nut. As the screw moves, the diameter of banding portion changes. Four Mongrel dogs ranging from 15 kg to 20 kg in weight underwent the banding of the mid portion of descending aorta with this devices through the left thoracotomy. One month after operation, we evaluated the pressure changes by controling the banding with the devices and then the dogs were sacrificed to study the microscopic changes in the aorta. The diameter and circumference of the band could be easily and finely adjustable by the screw control. The pressure recordings . revealed a linear increase and decrease in pressure gradient according to percutaneous ad;ustment of the banding device. Since the banding device can be easily placed and simply adjusted percutaneously, we hope the banding device may be applicab e clinically to improving the safety of pulmonary artery banding and debanding procedures in the future.

The growth accelerator period from a child's body into an adult body is a huge transition characterized by rapid growth in the near term. Body shape changes at this time of growth should be continually studied because they can result in different outcomes due to various variables. This study is basic study for the production of a junior brassiere patternmaking was conducted to separate the upper torso and breasts of adolescents by growth level. Analysis was conducted by age classification according to sales trends. In this study. 3D body shape data of Korean girls, Based on the 6th Size Korea data, analyzed statistically the upper body and breast according to the rate of growth. The results of this study represent the basis for the development of a junior brassiere to help lead a better life in regards to clothing. The study used 3D-data from girls aged 13 to 18. The analysis indicates that the upper body is in a different shape at age 15 with an increasing circumference, width and shoulder length of the chest; in addition, the sides are analyzed differently, suggesting that the brassiere configuration should be made differently at age 15. The breast form also showed different growth patterns at age 13 and the result was that the shape of the cup in brassiere should be configured differently depending on type.

The aim of this study was to develop a body type suitable for adult men aged from their 20s to their 40s and to present a method of drafting related patterns. To this end, the somatic surface pattern data from previous studies were used. The research method involved drafting torso patterns for each type by setting and distributing the ease to the somatic surface pattern. Appearance evaluation was performed with virtual clothing. Then, the torso pattern for each body type was completed and presented as a draft method. SPSS was used for data analysis in this study. The research results are as follows. Types 1, 2, and 3 were set to 7%, 6%, 5%; 7%, 6%, 4%; and 6.5%, 7%, and 6% for chest, waist, and hip circumference measurements, respectively. The ratio of front to back was 50%:50%, 50%:50%, and 50%:50% of the spare for each body part for Type 1; 70%:30%, 50%:50%, and 60%:40% for Type 2, and 60%:40%, 70%:30%, and 60%:40% for Type 3. A tight-fit torso pattern for each body type suitable for adult males in their 20s to 40s was drafted, which was modified and supplemented through the evaluation of the first and second virtual wear. Considering the practicality of this approach, for generalization of the patterns, the items of the pattern were converted into a drafting method and presented as a draft method.

This study aims to develop a fitted torso pattern suitable for males in their forties and fifties who are obese-a group that accounts for more than fifty percent of men in this age group-using a 3D virtual fitting program. Size Korea's 2022 data for obese males in their forties and fifties is utilized for this study. In terms of the research method, a 3D program (CLO 3D) is used to implement the target group's various body types and to apply fitted torsos that enable verification and evaluation of the pattern's fit and ease. The characteristics of fitted torso patterns for obese bodies are as follows: the front centerline is a profile line; shoulder darts are added by reflecting waist-abdominal protrusion in the front panel; and shoulder, arm, waist, and center-back darts are constructed for the back panel. For obese bodies, the minimum circumference ease amounts should be approximately 6-7cm for the chest, 6cm for the waist, and 6-7cm for the hips. Based on an evaluation of the virtual fit of the developed fitted torso pattern, the data shows that a pattern (foundation) such as this is well suited for obese body types with an average of 4.67/5 points for reverse triangular obesity, an average of 6.67/7 points for log obesity, and an average of 6.69 points for the ease amount.

In this study, the sizing systems of 40 unisex sweatshirt brands were analyzed to collect the size information needed to produce unisex clothing. Each size specification was compared with the body size distribution and percentiles of men and women aged 18 to 29. Depending on the brand, unisex sweatshirt sizes ranged from 1 to 8. Despite being unisex apparel, three brands offered only one or two sizes. Out of the brands surveyed, 50% were found to offer four or five sizes. Out of the 40 brands, 25 used letters such as "S," "M," and "L" to indicate the size designation. More than 92.5% of the brands included M and L, and the sizing system tended to focus on larger sizes such as XL and 2XL rather than smaller sizes such as XS and S. The size specifications of shoulder width, chest circumference, sleeve length, and total length were compared with the body size distribution and percentiles of men and women aged 18 to 29. The distribution of each size specification mostly appeared in a section larger than the men's body size. The size specifications of unisex sweatshirts were set close to or larger than men's sizes and hardly represented women's sizes. To increase consumer satisfaction with unisex clothing, establishing a size standard that could accurately reflect the body size distribution of men and women was found to be imperative. Such a size standard could also help each brand specify or diversify its target and differentiate itself with other brands.

Kojedo is the second largest island in Korea and a total population of 115,500 is living on the island of 394.69 sq. km. Under the direction of three nutrition professors, nutrition surveys in two villages in Kojedo, namely Siljun Ri in Hachung Myon and Soowol Ri in Shinhyun Myon, were carried by 30 college senior students majoring in nutrition from August to 20 August 1977. From a total of 176 households of the two villages, 67 households were randomly selected and 390 family members of the households were subjcets of the nutrition surveys. The precise weighing method was used in evaluating the kinds of foods and nutrient intakes of the subjects for three consecutive days. Thirty-seven pre-school children aged between 3 to 6 years and 27 fertile women were examined for biochemical findings and physical status. The main purposes of the surveys are to provide baseline data on nutrition in Kojedo Island for the Kojedo Community Development Project and to compare the nutritional status of the villages of Siljun Ri and Soowol Ri. Siljun Ri is located in the pilot project area of the Koiedo Community Health Project sponsored since December 1970 by the Christian Medical Commission of the World Council of Churches. While Soowol Ri is a control village for comparison. The results obtained are summarized as follows: Food Intake The average food intake per person per day in Siljun Ri, 1064 grams (91.7% in vegetable foods and 7.6% in animal foods) was 90 grams more than that of Soowol Ri, 974 grams (92.8% in vegetable foods and 5.9% in animal foods). However, the food intake per pre-school child in Siljun Ri, 485 grams (92.6% from vegetable foods and 6.4% from animal foods) was 21 grams lower than that of the Soowol Ri, 506 grams (88.5% from vegetable foods and 6.5% from animal foods). The average intake of beans was 16 grams(1.5% out of the total food intake) in Siljun Ri and 21 grams(2.2% of the total food intake)in Soowol Ri. The villagers should be guided for more consumption of soybeans to improve the quality of protein intake from vegetable foods. Nutrient Intake The adult intake in Siljun Ri and Soowol Ri were 2,529 kcal and 2,511 kcal respectively. The average energy intake of pre-school childen in Siljun Ri was 948 kcal and that for adult and 1,500 kcal for childen aged between 4 to 6 years-given by the Korea FAO Association, the diets in both villages were not adequate. Average daily protein intake of the subjected adult in Siljun Ri was 78.4 grams and that of Soowol Ri was 76.2 grams, while pre-school children took 30.7 grams in the former village and 31.7 grams in the latter village per child per day. The protein intake in both villages were lower than the recommended allowances, 80 grams for adult and 45 grams for $4{\sim}6$ years childen, and animal protein intake of the all subjects was very much lower than the RDA. The main charecter of the diet has been found low in quality of protein and high in carbohydrate. The calcium intakes of the pre-school children in both villages, 251.9 milligrams in Siljun Ri and 218.8 milligrams in Soowol Ri, were very much lower than the recommended allowance of 500 milligrams per day. It is apparent that the diet for children should be supplemented with calcium. Among the vitamin group, the daily average intakes of vitamin A and $B_{2}$(thiamine), $B_{2}$(riboflavin), C(ascorbic acid), and niacin were not adequate for the children in both villages. Especially the intake of riboflavin, 0.4 milligrams in both village children, was much lower than the RDA, 0.9 milligrams per day. Physical Characteristics Average height, weight, chest and head circumference of the pre-school children in both villages were similar to those of the Korean standard given by the Korean Paediatrics Association except that the average height of pre-school boys in Siljun Ri was 8 cm higher than the Korean standard of 105 cm. The mean values of upper arm circumference and skinfold thickness of pre-school boys in both villages were the same, 15.4 cm for upper arm circumference and 6.8 mm for skinfold thickness, but the mean values of those of the girls in Siljun Ri were higher than those of pre-school grils in Soowol Ri. Biochemical Findings Avera ge hemogobin value of boys and girls in both villages was the same, 11.1 grams per 100 ml of blood. The incidence of anemia (Hb value below 11g/100ml) was similar in both viltagesr 36.4% for boys and 50% for girls in Siljun Ri and 37.5% for boys and 50% for girls in Soowol Ri. Average hemoglobin values of fertile women were 10.7g% in Siljun Ri and 10.8% in Soowor Ri. The incidences of anemia(Hb valre brlow 12g/100ml) were 100% in Siljun Ri and 86.7% in Soowol Ri. The anemia of these subjects may be caused mainty low intake of good quality protein and iron intake from vegetable food. Recommendation In general, the nutritional status of a community health pilot village is not higher than that of control village due to the lack of nutrition improvement guldance services. Nutrition education should be delivered to the villagers as a main part of the health education artivities. The emphasis should be on building better health through bttter food habits and better food production as well as on preventing malnutrition and diseasrs. It can be an invaluable part of community developnent. Since nutrition is considered to be at least one-half of MCH care, no village or home visits should be made without careful provision for teaching and demoastrating something simple and practical on nutrition. The nurse, midwife, and village health worker should be the chief promoters of nutrition.

Background: It is very important to determine the surgical anatomy of the aortic root when performing spreading aortic root preserving heart surgery. This study focuses on the surgical aspect of the aortic root anatomy by performing dissection of Korean cadavers. Material and Method: The subjects were 62 cadavers. We measured the intercommissural distances, heights of the sinuses and the circumference of the sinotubular junction and the aortic annulus. Result: The mean age of death was 61.3 years. The intercommissural distance for the right coronary sinus was $0.73{\pm}2.23mm$, that for the non coronary sinus was $19.34{\pm}2.03mm$, and that for the left coronary sinus was $18.58{\pm}2.15mm$. The height of sinus was $20.59{\pm}2.48mm$ for the right coronary sinus, $18.61{\pm}2.26mm$ for the non coronary sinus and $17.95{\pm}19mm$ for the left coronary sinus. The circumference of the sinotubular junction was $70.73{\pm}5.94mm$ and that of the aortic annulus was $77.94{\pm}5.63mm$. There is no correlation between age and STJ, aortic annulus and the ratio of STJ of aortic annulus respectively (p=0.920, p=0.111, p=0.073). The tilting angle of the sinotubular junction and aortic annulus is from $2.03^{\circ}$ to $7.77^{\circ}$ $(mean=4.90^{\circ})$. Conclusion: The intercommissural distance and the height of the sinus were largest in the right coronary sinus, and the position of the sinotubular junction to the aortic annulus is obliquely tilted levo-posteriorly.
