The present experiments differning from that conducted by agriculturists with the first consideration of food or seed production were performed in order to investigate the density effect on dry matter production in the artified population of maize. Three experimental plots were established and one seed was sown in the first plot, 2 seeds in the second plot and 3 seeds in the third plot, respectively. The space of each ridge was designed with 30cm in width and 50cm in length. The space of each seed was 4cm and the growth amount by density was measured through three times. The results obtained are as follows: 1) The total growth amount per unit area was in the order of the third, second and first plots until the second sampling. At the third sampling the whole plots showed almost the same growth amount except the first plot which showed a slightly smaller amount. 2) The growth amount per individual plant was in the order of the third, second and first plots until the second sampling, while the first plot showed drastic growth compared with the other two plots at the third sampling. 3) The growth amount by each organ(leaf, stem and root) of the plant body was markedly abundant in the stem of the non-productive part compared with that in the leaf of the productive part. Especially the root was affected remarkably by density and the first plot showed an abundant growth in comparison with the other plots which were too poor to resist the gound surface.

Purpose: This study was investigated basic data for verifying the effect of rope skipping exercise by comparing and analyzing the effects on the body composition of female students. Method: The subjects of this study were 12 female college students and the rope-skipping exercise program was conducted after the purpose and process of this study were explained and the consent of the subjects was obtained. And we used the body composition analyzer (Inbody 520, Korea) to measure before and after exercise of Body Mass Index (BMI), Percentage Body Fat (PBF) and Waist Hip Ratio (WHR). Result: First, the daily living group and the rope-skipping exercise group showed a significant difference in the BMI according to the period and there was no significant difference between the groups. Second, in the PBF, there were no significant differences in the duration, interaction between duration and group and differences between the groups. Third, in the WHR, there were no significant differences in the duration, interaction between duration and group and differences between the groups. Conclusion: BMI of each group according to the period was significantly different between before exercise and 6 weeks after exercise.

This study aimed to investigate the effects of somatotypes and body-related variables such as body exposure and body satisfaction on underwear evaluative criteria. Usable questionnaires were obtained from a total of 250 male and female students in their 20s. The data were mainly analyzed by t-test, ANOVA and analysis of variance using SPSS ver. 21.0. The results of this study are as follows: First, differences between underwear and outerwear evaluative criteria were found. For example, size, comfort and washing were important for the underwear but design, brand and fashionability were meaningful for outerwear. Price, color, material, and sewing were important for both outerwear and underwear. Second, the groups divided by somatotypes, a thin person group, a moderate person group and a fat person group, showed no difference in underwear evaluative criteria. Members of all the somatotype groups evaluated underwear similarly. Third, the groups divided by body image distortion showed different evaluative criteria for underwear. The negative discordance group emphasized the importance of the practicality factor, but the positive discordance group stressed the significance of the symbolism factor. Finally, the groups divided by body exposure and body satisfaction showed different evaluative criteria for underwear, too. The effects of socio-cultural variables on the underwear evaluative criteria proved to be significant.

This study investigates the effects of sociocultural influences and body image on appearance enhancement behaviors (facial management, clothing selection, and weight/figure management). For data collection, a questionnaire was administrated to 562 female college students in Gwangju City, Chonnam area and Chonbuk area, Korea, from May 23 to June 10, 2011. To analyze the data, a SPSS 18.0 statistics package was used, and descriptive statistical analysis, frequency analysis, factor analysis, reliability analysis, and regression analysis were conducted. The results were as follows. First, sociocultural influences were divided into three factors: parental influence, media influence, and peer influence. Overall sociocultural influences had positive effects on appearance enhancement behavior. Second, body image was divided into two factors: weight-concern and appearance-concern. Sociocultural influences had significant effects on overall body image. Third, body image appeared to have positive effects on overall appearance enhancement behavior.

In this paper, we tried to find out what makes the students feel anxious to mathematics and the ways to decrease their anxiety by comparing two learning types, self-directed-learning and learning in a body, by means of continuous observation and interviews. To perform this study, two classes of self-directed-learning and other two classes of learning-in a body were chosen from the third year-students in Wando Middle School in Chollanamdo. In this study, we obtained the following results: 1. In high group in math grade, students in self-directed-learning are less anxious than students in learning-in a body. 2. In average group in math grade, students in self-directed-learning are much more anxious than students in learning-in a body. 3. In low group in math grade, both students in self-directed-learning and students in teaming-in a body feel anxious about math and there is no difference between them. 4. Anxiety about math hove positive influence on high group in math grade. 5. Anxiety about math have negative influence on average and low groups in math grade. Especially, low group students had no interests about mathematics because of their math anxiety. We observed that some students got over the math anxiety to some meaningful extent by means of interviews or appropriate advices, and became to have confidence and interests in mathematics.

Second, there are some differences in adolescents' body esteem according to the sociocultural attitude toward appearance. Receptive group had the lower level on body esteem than unreceptive group. Third, there are significant differences in adolescents' clothing behaviors according to the sociocultural attitude toward appearance. Receptive group had the highest psychological dependency of clothing, clothing interest, clothing individuality, and clothing conformity among 4 groups.

The purpose of this study is to categorize and analyze the body shape of obese Korean men that are needed for industrial design. Using the anthropometric data that were surveyed through the 5^th Size Korea project, this study was conducted in four steps mostly through the multivariate statistical analysis. In the first step, Broca, BMI, WHR indices are used to define obesity and select obese men from Korean adults and teens. After 34 human anthropometric variables are supposed to be related to obesity were extracted through an expect survey. In the second step, a factor analysis was executed for those human anthropometric variables. Through this analysis, we obtained the human body factors that are related to the representation of obesity. Then the third step, we used a cluster analysis from the result of the factor analysis. And ANOVA analysis was also conducted to obtain the critical obese human anthropometric variables. In the final step, we found the characteristics of the body types of obese men according to clusters and ages. The body types of obese men classified in the study are expected to be applied to product design for clothing, furniture, automobile packaging, etc.
