A statistical method was developed to examine the US navy women's sizing system. Subjects including 906 navy female personnels were classified into seven groups based on the body type. Regression analyses were performed within seven groups to determine the sizing system maximizing the fitness of clothing in each group. New parameters were developed and used to statistically investigate the fitness level based upon boty navy sizing system and regression based system in this study. A customizef SAS program was used to compute the fitness levels. Results indicated that the navy sizing system showed lower fitness level in most groups except Juniour than the regression based system. It was concluded that the current method with new parameters could be used as an objective tool to evaluate the existing or new sizing system. This method can be further validated in other sample populations.

This study was conducted in order to analyze draping and flat pattern according to jacket design, and provide basic materials for developing a jacket pattern that can enhance fitness, functionality, and aesthetic expression of clothes by reflecting esthetic expression of draping and efficiency of flat pattern at the same time. For the experimental jacket designs of a one-piece sleeve jacket and a two-piece sleeve jacket were selected among the entries of the designer Rubina for 2014 F/W Seoul Fashion Week. Designer brand Rubina usually produced clothes using draping and the designer brand company provided the experimental patterns for the study. We also had flat patterns of the same design and size specifications designed by a flat patternmaker who has 30 year-experience in flat pattern like Rubina. The test apparel jacket was made of 20's cotton yarns. Three models wore the jackets and evaluation on appearance fitness was conducted by 7 members in an expert panel group from August 10, 2015 to September 10, 2015. As a result of appearance fitness analysis on one-piece sleeve jacket, there were significant difference in 4 items among 17 items in terms of overall appearance. The appearance of jackets by draping had higher score than those using flat pattern. As for two-piece sleeve jacket, there were significant differences in 7 items among 17 items related to overall appearance. As for the items related to sleeve, 5 items out of 13 showed significant differences. Except for one item, appearance of jackets using draping had higher score than flat pattern. As for motion fitness, draping was evaluated to be more comfortable. Applying the items with high scores in appearance and motion fitness in draping to flat pattern, The study suggests a new jacket pattern development that would increase the satisfaction of consumers for future research.

The Purpose of this study was to evaluate the marginal fit of ceramo-metal crown according to the different ceramo-metal alloy types and the curvature of labio-cervical margin. Degudent $G^{(R)}$ as precious and $Verabond^{(R)}$ as non-precious ceramo-metal alloy were used. The abutment was preparaed with two different curvature types : a normal curvature type and a pronounced curvature type. 20 crowns were farbricated using four different combinations and their marginal fits were measured at 3 consecutive stages (before degassing, after degassing, after glazing) using microscope under 200 magnification. The results were as follows: 1 . Marginal fitness before degassing. The groups of precious ceramo-metal exhibited better marginal fit than the groups of non-precious ceramo-metal with significant difference(P<0.05) . In the same ceramo-metal groups, the normal curvature group exhibited better marginal fit than the pronounced curvature group but without significant difference(P>0.05). 2. Marginal fitness after degassing. By degassing, the group of pronounced curvature and non-precious ceramo-metal was deformed the most, and the degree of margin fitness of each group was the same as before degassing. 3. Marginal fitness after glazing The group of normal curvature and precious ceramo-metal exhibited better marginal fit than the group of pronounced curvature and non-precious ceramo-metal with significant difference(P>0.05), and the degree of margin fitness of each group was the same as before degassing.

In order to evaluate the fitness and the degree of rounding of porcelain margins in collarless metal cermic restorations, collarless metal ceramic restorations were fabricated with shoulder margins of 90 and 120 degress, each consisting of ten specimens, on master dies through the direct lift technique. And ten metal ceramic restorations with a shoulder 90 degrees were fabricated. All specimens were embedded in resin and sectioned longitudinally. The sections were observed under a stereomicroscope and photographed(${\times}$200). The labial marginal gap between the die and the porcelain margin were measured with a scale. The space between the porcelain margin and the die, that is formed from marginal rounding and cementation were calculated with a computer coordinating area curvimeter. The following results were obtained. 1. There was no statistical difference between the fitness of porcelain margin of collarless metal ceramic restorations and marginal fitness of metal ceramic restoration. 2. There was no statistical difference between a shoulder of 90 and 120 degrees in the fitness of porcelain margin of collarless metal ceramic resorations. 3. Collarless metal ceramic restorations with a shoulder of 90 degrees and 120 degrees showed significantly more labial marginal rounding than metal ceramic restorations. 4. There was no statistical difference between a shoulder of 90 and 120 degrees in rounding of porcelain margin of collarless metal ceramic restorations. According to the results, rounding of porcelain margins can be observed in collarless metal ceramic restorations. Thus, there is a need for improvement in dental materials and techniques to minimize this problem, Furthermore, care should be exercised during the clinical procedure.

Proper nutrient intakes and physical fitness focus one's attention on health promotion. This study was conducted to investigate nutrient intakes and physical fitness by BMI in middle school students. Health-related questionnaire, dietary intakes, food frequency questionnaire and physical fitness were studied. There were no significant differences in health-related questionnaire, food frequency questionnaire and physical fitness by BMI, but several nutrition intakes, preference of salty tastes and the proportion of iron deficiency of female students were significantly different by BMI. Although the female obese group (BMI 85 - 100 percentile) had decreased the proportion of iron deficiency and increased fish intake frequency than other groups, obese females did not show better physical fitmess than other groups. And the average Ca intake was below $75\%$ of Korean RDA in both male and female students. Significantly positive correlation was found between calorie intake and push-up of normal (BMI 15 - 84 percentile) male students (r = 0.29), also significantly negative correlation was found between protein intake and 50m dash of normal female students (r = 0.22). And significantly positive correlation was found between beans and bent knee sit-up of normal male students (r = 0.25), and significantly positive correlations were found between beans, meat, eggs, green & yellow vegetable and sit and reach (r = 0.20, r = 0.28, r = 0.21, r = 0.19) and significantly negative correlation was found between beans and long distance race of normal female students. Therefore, this study suggests that proper nutrition and non-obese states should be achieved for health promotion in middle school students.

Aging is associated with decreased energy expenditure, thermogenesis and energy requirements. Maintenance of physical fitness of the elderly has been reported to reduce the rate at which the basal metabolic rate, muscle strength, skeletal muscle mass and bone density deteriorate. Skeletal muscle disease is known to increase the risk of physical disability and psychological problems. This study was conducted to investigate changes in disability, emotional problems, body compositions, obesity indices and nutrient intake levels according to physical fitness with the elderly in rural areas. According to the results, physical fitness was negatively related with Activities of Daily Living(ADL, p<0.05), Instrumental Activities of Daily Living(IADL, p<0.001), Body Mass Index(BMI, p<0.001) and abdominal obesity(p<0.05), while it showed a positive correlation with the General Self Efficacy Scale(GSES)(p<0.001) and nutrient intake(p<0.05). When changes in these factors were compared according to the range of quartile of the Fullerton Advanced Balance Scale(FAB Scale), GSES(Q1=35.3, Q2=43.5, Q3=53.2, Q4=51.9, p<0.001), BMI(Q1=36.1%, Q2=34.7%, Q3=33.2%, Q4=28.6%, p<0.01), abdominal obesity(Q1=1.02, Q2=0.99, Q3=0.97, Q4=0.94, p<0.001) and nutrient intake(Q1=71.1%, Q2=75.4%, Q3=80.6%, Q4=80.2%, p<0.05) differed significantly. Taken together, these results suggested that better physical fitness would lead to a reduction in negative factors including physical disability and obesity indices, but to an increase in positive factors such as GSES and nutrient intake. The results of this study are expected to be used as basic data for the development of programs to promote the health of the elderly in a local society.

유전자 알고리즘은 원하는 최적해를 찾기 위해서 개체 집단의 크기를 가능한 크게 유지하여야 한다. 하지만 실제 문제에서 개체의 적합도를 평가하는 것이 어려운 경우가 많기 때문에 큰 집단의 모든 개체에 대하여 적합도를 평가하는 것은 많은 시간과 비용을 요구한다. 이에 본 논문에서는 집단의 크기를 크게 유지하되 클러스터링에 의해 대표 개체만을 평가함으로써 효율을 높이는 퍼지 글러스터링 기반의 국소 평가 유전자 알고리즘을 제안한다. 나머지 개체들은 대표 개체로부터 간접적으로 적합도를 분배받는다. 다수의 집단에 소속되는 개체들의 경우, 하드 클러스터링 방법으로는 정확한 적합도 분배를 하기 어렵기 때문에 퍼지 c-means 알고리즘을 사용하였고, 클러스터 결과인 퍼지 소속 행렬에 의해 적합도를 배분하였다. 9개의 벤치마크 적합도 함수에 대하여 6가지 하드 클러스터링 알고리즘을 적용한 유클리디안 거리와 피어슨 상관계수에 의한 적합도 배분 방법과 본 논문에서 제안하는 방법을 비교 실천한 결과, 제안한 방법의 우수한 성능을 확인할 수 있었다.
