  • The purpose of this study was to get a data which can provide a basis for future direction in nutritional education and to build up right eating habit and to find the way how to improve food life and the nutritional supply by evaluating the current nutritional intake of average middle school girls through the survey study of their daily food intakes and physical status. The survey of nutritional intakes and physical status in two girls middle schools, namely Jang'hung girls middle school at Jang'hung Up and Bo'song girls middle school at Bo'song Up, were carried by teachers majoring in Home Economics and nurse-teachers from 5 July to 7 July 1983. From a total of 1080 subjects of two girls middle schools, 887 subjects were surveyed. The results obtained from survey are summarized as follow: 1) Physical Status Average height, weight and chest girth of subjects in both middle schools were much lower than the Korean average standard (p<0.005${\sim}$p<0.001) and t-score of differences between two middle school girls were not significant. Rohrer index, nutrition rate and physique rate were also lower than Korean averag standard through all the ages in both girls middle schools. Menarche appeared mainly between the age of 13 to 15 (91.55 %), with a mean age of 14 (35. 01 %) and which was experienced by the subjects of 51.52 percentage among total surveyed Iniddlf school girls. 2) Nutritional Intakes The average daily intakes of all nutrient except iron, vitamin A, thiamin, ascorbic acid and niacin was lower than Korean Recommanded Dietary Allowances (RDA) . Especially average intake of calorie and calcium were much lower than Korean RDA(p<0.001) while average intake of thiamine and ascorbic acid were much higher than Korean RDA (p<0.001). T-score of differences of iron, thiamin, riboflavin between two middle school girls were very significant (p<0.001). Generally iron and riboflavin were the highest rate of intakes through three meals and breakfast took charge of considerable amount of all nutrient intake without omitting anything (about 30 % of daily nutrient intake). The nutrients of which ratio of nutrient intake by snack was more than 16.7 % were vitamin A, thiamin, riboflavin, ascorbic acid etc. and snack foods which were intake frequently in both middle school girls commonly were fruits, milk and milk products, bread and biscuits in sequence. 3) Correlations and t-score between physical status, menarche and nutrient intakes. Average intake of calorie at Jang'hung area was positively correlated with height, weight, nutrition rate and physique rate and this correlation was very significant (p<0.005). Average intake of calorie was also correlated with chest girth and Rohrer index (P<0.05). At Bo'song area, averse intake of riboflavin was negatively correlated with all the items of physical status (p<0.05-p<0.005), vitamin A was negatively correlated with chest girth and Rohrer index (p<0.05 respectively) and thiamin was also negatively correlated with chest girth, Rohrer index and nutrition rate (p<0.05 respectively). Especially niacin showed a negative cor-relation with all the items of physical status very significantly (p<0.005).The time of menarche showed a positive correlation with iron in both middle school girls commonly P<0.05 at Jang'hung, p<0.10 at Bo'song).

  • This study analyzed the present uniform satisfaction, uniform satisfaction followed by physical satisfaction, attitude for uniform, purchase attitude for uniform, satisfaction for design, preference for design, and attitude for uniform alteration behavior by distributing questionnaires to high school girl students in Daejeon City. The results of the study are as follows. The study distributed questionnaires to 319 high school girl students in Daejeon City and analyzed the satisfaction factors for their uniforms. As the result, this study induced four factors. The average value of each factor appeared in order of symbolic satisfaction, management satisfaction, activity satisfaction, and aesthetic satisfaction to show that high school girl students were the most dissatisfactory in aesthetic satisfaction. When the study examined the realities of uniform alteration, it showed that 71.2% of them altered their uniforms. In the alteration of a jacket and a skirt, they altered their jackets shortly and tightly in the mass in the order of: waist measurement, jacket length, breast width, shoulder width, and girth of the chest in a jacket. For a skirt, they altered their skirts tightly as a jacket in the order of: skirt length, waist measurement, and the girth of hip.

  • The purpose of this study is to measure middle aged men's bodies around the ages of thirty-five through filly-five, whose age-group undergoes drastic changes on their body shapes. Further, body shapes are grouped based on the measurements, and pattern making methods are presented in order to effectively make up for the undesirable body features of middle-aged men. In order to develop patterns fit for middle aged men's body shapes, the regression which reflects physical characteristics was applied for the experimental shirts pattern, instead of comparative patterns which applies the same equation. For the two body types classified above(Bend-forward Type and Lean-back Type), correlation among the factors necessary for pattern design was considered and the regression was formularized accordingly. To validate the regression, the same amount of ease as in the comparative patterns was applied to the chest girth, and reasonable ease to the armhole depth and neck girth. In this way, experimental shirts patterns fit for the body types were developed. After the modification through the wearing test, the experimental shirts pattern was completed as herein.

  • Phenotypic characterization and body biometric in 13 traits (height at withers, body length, chest girth, paunch girth, ear length, tail length, length of tail up to switch, face length, face width, horn length, circumference of horn at base, distances between pin bone and hip bone) were recorded in 233 adult Gojri buffaloes from Punjab and Himachal Pradesh states of India. Traits were analysed by using varimax rotated principal component analysis (PCA) with Kaiser Normalization to explain body conformation. PCA revealed four components which explained about 70.9% of the total variation. First component described the general body conformation and explained 31.5% of total variation. It was represented by significant positive high loading of height at wither, body length, heart girth, face length and face width. The communality ranged from 0.83 (hip bone distance) to 0.45 (horn length) and unique factors ranged from 0.16 to 0.55 for all these 13 different biometric traits. Present study suggests that first principal component can be used in the evaluation and comparison of body conformation in buffaloes and thus provides an opportunity to distinguish between early and late maturing to adult, based on a small group of biometric traits to explain body conformation in adult buffaloes.

  • This study investigates the body satisfaction and fitness apparel depending on age and silhouette. The subjects were 254 females 20~50 years of age living in Chungju South Korea. There are various body types in women over the age of 35, the lower part of the body-development type, regular type, the upper part of the body-development type, and the rectangular body type. In addition, there is a lower satisfaction level in circumferences related with apparel fit, especially in the sleeve length, armhole, and crotch length. Therefore, a size system is needed that considers various body types in ready-to-wear clothing for middle-aged women. Design, color, and pattern are most important in clothing purchases by unmarried women, but the ease of laundry management and price discounts are the most significant for clothing purchases by married women. The upper part of the body-development type is unsatisfactory in the size-fit of sleeve length and shoulder width, but the lower part of the body-development type is unsatisfactory in the circumference of the waist, hip, abdominal, girth of skirt, and crotch length. The rectangular body type and the lower part of the body-development type are unsatisfactory in movement comfort, especially in hip girth and crotch length. The upper part of the body-development type is unsatisfactory in the movement comfort of the chest and elbow girth.

  • This study were to grasp the present situation of the pet wear market and the problem of pet wear, and to develop the pet wear pattern which agrees well to dog's shape and movements. We carried out survey research to analyze the actual pet wear market condition for a dog-lover, and movement analysis and sensory test to develop a pattern for Maltese which was the favorite dog among Korean. For data analysis, ANOVA with duncan test, T-test were conducted using SPSS statistic program(ver. 10.0). The results are as follows: 1. The results of the survey research, 75% of dog-lover had a pet wear and favorite was T-shirts. The problems of wearing T-shirts were 'too tight seam sleeve and bodice(front legs hole)', 'the clothes easily hang down' and 'easily taken off due to large neck size'. 2. The ease amount of the developed pattern was given according to the results of dog's shape and movement analysis, and the results of sensory test, there is a significant difference in the following items: depth of front neck line, front chest${\to}$abdomen curve, ease amount of sleeve, comfort level of leg parts. 3. The size of each parts of the developed pattern in this study were as follows : neck girth 27.0cm, body girth 40.0cm, back length 26.0cm, front leg girth 23.0cm, sleeve length 20.7cm, sleeve width 14.4cm. But, there exists some limits to generalize these results since dog's body size and shapes are various according to dog species. Therefore, further studies are needed to develop each pet wear pattern for each dog species.
