The growing concern for poor dietary habits among adolescents has prompted many researcher to study the adolescents' knowledge and beliefs on a number of nutrition-related issues. Following that precedent, this study was conducted to evaluate the nutrition knowledge of a sample of adolescents in a middle school in Ohio. The participants were 532 students in the sixth, seventh, and eighth grades between the ages of 11 and 13 from Shawnee Middle School in Lima, Ohio. The students were asked to answer a questionnaire CANKAP (Comprehensive Assessment of Nutrition Knowledge, Attitudes, and Practices), which measured their nutrition knowledge. The CANKAP questionnaire consisted of 20 questions for sixth grade students and 25 questions for seventh and eighth grade students. Also, the participants were asked to identify their gender. According to the result, nutrition knowledge of middle school children was weak. The findings indicated that females had higher mean nutrition knowledge scores than boys in the seventh and eighth grades. There was no significant difference in the mean value of nutrition knowledge between sixth grade boys and girls.

The objectives of the thesis were to investigate the general trends of clothing conformity and clothing attitudes and to figure out the relationships between clothing conformity and clothing attitudes, and differences of clothing conformity and clothing attitudes between different genders and ages. The conformity includes clothing conformity by informational influence, by identificational influence, and by normative influence. And the clothing attitudes are fashion interests, pursuit of individuality, clothing importance. It was turned out that three types clothing conformity were closely related with variables of clothing attitudes(fashion interests, pursuit of individuality, clothing importance). Particularly, the clothing conformity by normative influence was negatively correlated with pursuit of individuality. And other clothing conformities were positively correlated with the variables of clothing attitudes. It was also turned out that school girls marked high points on the clothing conformity by informational influence and by identificational influence. Middle school students were influenced by identification idol. Most of middle and high school students were believed to recognize the importance of clothing, and they were pursueing both fashion and individuality simultaneously.

Recent color plans in school buildings are made by experts through public offerings for prizes for designs etc in relatively many cases. But it is necessary to review if such color plans are actually well conform to students' emotions and what trend the color plans made as such have. Therefore, this study examined and analyzed the exterior colors of the school buildings planned by public offerings for prizes for designs and reviewed the result comparing to the color preferences of students that had already been studied to figure out the differences between existing theories and the realities. And it was examined what differences were existing in the trends of color plans and color images examined between each of school levels. The result of the study compared to theories is as follows. First, when the color distributions were reviewed for each school level, it could be confirmed that the overall distributions moved from Y category to B category and whereas warm colors were more widely distributed and the number of colors were greater compared to cold colors in case of elementary schools, the distributions of warm colors gradually decreased as school level moves to high schools. Second, the color use distributions of elementary school students were revealed to be more diversified than middle and high school students and also the number of colors used was 9.5 in average in elementary school and middle schools and high schools were similar to each other with average 5.86 colors in middle schools and 6.33 colors in high schools showing a little differences in color use distributions among school levels of elementary schools, middle schools and high schools. Third, in case of elementary schools, except main colors, both of subsidiary colors and emphasizing colors had the distributions of warm colors of R, YR, Y categories and cold colors of B, PB categories and this is also consistent with the results of existing research results indicating that low grade students prefor for warm colors and high grade students prefer for cold colors. Fourth, in case of middle schools and high schools, although the distributions of warm colors decreased, the distributions of warm colors and cold colors were revealed to be similar. This is considered to be consistent with the existing research results indicating that girl students prefer for warm colors even if their ages go up. Fifth, as for the images of main colors, subsidiary colors and emphasizing colors resulted from the comparisons by solid color Image Scales and adjective Image Scales, first, in case of main colors, natural images or clear images appeared the most in all of elementary schools, middle schools and high schools indicating that basically calmness is emphasized with soft images rather than hard images and static images rather than dynamic images. Also, in case of subsidiary colors or emphasizing colors, cheerful images or splendid images are also seen to decrease as school level goes from elementary schools to high schools in adjective Image Scales and this is considered to reflect the color sentiment differences between children and juveniles based on ages.

CHIME ages were obtained from monazites in metamorphic rocks from the Seosan and Siheung Groups in the Gyeonggi gneiss complex, Korean peninsula. Monazite CHIME ages range from 234 to 257 Ma, corresponding to the late Permian to middle Triassic Songrim disturbance due to the collision event between the North and South China blocks within the Gyeonggi gneiss complex in the Korean peninsula. The CHIME ages are consistent with the metamorphic ages from the Hongseong area (231 Ma, Kim et al., 2006) and the Odesan area (245-248 Ma, Oh et al., 2006b) in the Gyeonggi gneiss complex and are older than those from the Dabie-Sulu collision belt (220${\sim}$242 Ma, Yang or of., 2003; Liu et al., 2003, 2004) suggesting that the collision between the North and South China blocks had occurred earlier in Korea than China.

This study was performed to determine the voluntary range of joint mobility for middle-aged Korean adults. One hundred and eighty-eight subjects(99 males and 89 females) at the age range of 40 to 60 participated for this study. Thirty body movements at various joints were conducted to measure the range of joint mobility. Subjects were grouped by Rohrer's into four based on 25th percentile. The data were analyzed to see the differences of range of joint mobility between sexes and Rohrer's index groups. The results of this study and previous studies were compared to see the differences of range of joint mobility due to the aging. Results of this study indicate that females are generally more flexible than males. Significant differences were found to exist in fourteen movement between sexes and in ten movements, females have larger range of joint mobility than males. There were no significant differences in range of joint mobility may have a tendency to decrease with ages. The results of this study provide important information in dynamic dimensions for middle-aged Korean and can be used to design the various and work places for the middle-aged.

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.

The purpose of this study was to enhance the marital relationships of middle-aged couples in their 50s who either had retired or were approaching retirement and to develop marriage-enrichment program that would help them maintain a happy and satisfactory family relationship. In-depth interviews were conducted with middle-aged couples in their 50s who had enrolled in the program. Developed based on the relevant literature and our own needs analyses the program was organized into three areas, family relationship, life management(time, leisure), and life plan for old ages. The program consisted of five sessions of 120 minutes each. Participants attended the program's lectures and activities. Pre and post-tests were conducted to examine the program's effectiveness. The post-test results showed improvement over the pre-test results, so we can conclude that this program would appropriate for improving the marital relationships of middle- aged couples in their 50s both before or after their retirement.

This paper studied why middle-aged group is using active wear as casual wear. First, we can think of 'comfort', 'ideal body shape', 'trend', 'functionality', 'economy' for the reasons. We categorized the incentives as 'comfort/functionality pursuits', 'trend/economy pursuits', and 'ideal body shape pursuits'. Studies showed that statistically significant number of men pursue comfort and functionality, and statically significant number of women pursue trend and economy. Second, this study shows that the number of consumers who use the active wear in daily lives is greater than that of those who use it only for outdoor activities. The difference was statistically significant in T-shirts and pants. The most frequent usage was in social activities, and the next frequent usage was in cultural activities. The reason is that currently, middle-aged consumers are actively participating in social gatherings than any other activities. Especially, considering that the men wear active wear more than the women do, development of the product as men's casual wear that is compatible with other apparels will be necessary. We expect this study will be used as the preliminary data for a marketing strategy targeting the middle-ages.

It is known that human saliva includes various kinds of salivaru proteins that show genetic polymorphism. Withrespect to salivary protein polymorphism, this study was conducted on 160 healthy Koreans between the ages of 20 and 29 chosen randomly : their parotid slaiva was collected, freeze-dried, and horizontally electrophoresed over acid-urea starch gel. Aluminum lactate-lactic acid was also used as buffer solution. The gel was stained with amidoblack 10B/1% acetic acid solution, and then destained with 0.5M H2SO4 solution. Accordingly, the parotid middle-band protein(Pm) identified, and its phenotypes and gene frequency were obtained. The obtined results were as follows : 1. The phenotypes of parotid middle band protein(Pm) observed in parotid saliva of the 160 Koreans were Pm(+) in 91 people (56.9%) and Pm(-) in 69 people (43.1%) 2. The gene frequency of Pm+ was 0.343, and that of Pm-waw 0.657. 3. The gene frequency of parotid middle band protein (Pm) obtained from Korean's parotid saliva was midway between that of Japanese and Chinese.
