The purpose of this study was to evaluate the obesity and weight control prevalence according to the gender and weight control attempt among middle school students in Seoul and Gyeonggi-do, Korea. The mean age of subjects were 14.4 years old. The mean height, weight and BMI value of boy students were 164.0 cm, 53.0 kg, and $19.7kg/m^2$, respectively, and the mean height, weight and BMI value of girl students were 159.4 cm, 49.8kg, and $19.6kg/m^2$, respectively. Both weight and BMI value of the weight loss attempt groups were significantly heavier and higher than those of the other groups (p < 0.01). In the perception on the body image, the girls perceived themselves to be more fat compared to boys, and the weight loss attempt group perceived their body image to be more fat compared to the other groups (p < 0.001). As for the interest degree of weight control, the interest degree of girls was higher than that of boys (p < 0.01). According to weight control attempt, in the order of the weight loss attempt group, the weight gain attempt group and the no weight control attempt group, the interest degree was significantly higher (p < 0.001). In the frequency and hours of exercise, there was significant difference by gender (p < 0.001). According to weight control attempt, the weight gain attempt group exercised more frequently than the other attempt groups (p < 0.01).

This study aims to improve the situation in which accurate job information for small and medium-sized enterprises is not known and it is difficult to identify jobs that meet the preference criteria from the perspective of the 'employer brand'. To this end, through a hierarchical regression analysis of 700 young job seekers, the factors affecting the intention to get a job centered on five value factors (Interest Value, Social Value, Economic Value, Development Value and Application Value) were identified by reflecting the brand categorization theory. As a result of the analysis, it was confirmed that young job seekers are more interested in work culture, environment, and utilization of their majors, which directly affect job seekers, rather than characteristics of companies such as talent development, products, services, and management, and are influenced by their intention to work. This suggests that the job policy for SMEs needs to be changed from the existing quantitative support-centered to a qualitative improvement that strengthens the use of platform-centered job information.

High school 'science' in the 2009 revised curriculum in Korea was developed for the purpose of enhancing students' scientific literacy needed for citizenship in a democratic society. For this analysis, 'science' includes a variety of scientific topics from the origin of the universe to the birth of life, and the relationship between technology and modern society. It aims to make students understand the process of scientific inquiry and foster interest and curiosity about science. On the other hand, interest has been studied as a psychological construct to affect academic achievement and career selection of students. In this study, the authors investigated students' interest in high school 'science' in view of the 2009 revised curriculum. To carry this out, a survey tool was developed according to previous research, with 997 high school students' responses analyzed with descriptive statistics and factor analysis. The result showed that the students' interest in high school 'science' in view of the 2009 revised curriculum can be interpreted into three dimensions such as motivation, activity, and topic, which has several sub-dimensions. Students' interest in motivation dimension was higher than in activity or topic dimension, while the average value was slightly higher than the middle value. They showed different distribution of interest by gender and job orientation, especially in activity and topic dimensions. From this study, the authors can infer the multi-dimensional property of students' interest in high school 'Science' and the different distribution of interest by dimensions.

The modern convenient life formed by industrial development becomes lack of exercise and takes an interest in diet. Specially, professional walking shoes is developed as people take an interest in jogging, Those shoes, professional walking shoes or Dietshoes, increase exercise effects by change of heel types. Therefore, this study investigated motility effects by EMG experiment in order to measure Muscle Activities (MA) while wearing diet shoes (backless). Experiment was conducted by EMG measurement, from calf (gastrocnemius muscle), thigh (vastus muscle) and waist (erector spinae muscle), of 12 high school students. Exercise effects between the two shoes were analyzed by EMG (MF; Median Frequency, MPF; Mean Power Frequency, ZCR; Zero Crossing Rate). Results showed that the Dietshoes(MF: 48.21Hz, MPF: 65.0Hz, ZCR: 100.6Hz) had larger EMG value than that of Normal shoes(MF: 40.47Hz, MPF: 58.04Hz, ZCR: 82.09Hz). Also, in MA, the highest activities are showed in the calf, the second one is in waist, and last one is in thigh during gate. ANOVA between shoes in measurement parts showed significant effects in MF (gastrocnemius: p-value=.022, vastus laterals: p-value=.037, erector spinae: p-value=.082), MPF (gastrocnemius: p-value=.032, vastus laterals: p-value=.046, erector spinae: p-value=.090), and ZCR (gastrocnemius: p-value=.000, vastus laterals: p-value=.004, erector spinae: p-value=.134). And MA of Dietshoes is higher than that of Normal shoes, and decreasing rate of MA in Dietshoes is less than that of Normal shoes. Thus, this study validates exercise effects of Dietshoes.

This study aimed to identify factors influencing awareness and interest in male nail care and nail art among people in their 20s and 30s, using a survey that included 390 men and women. The survey consisted of sub-factors, including awareness of appearance management, interest in nails, perception of male nail care and nail art, behavioral factors in nail care, and image factors in nail care. The results showed that the overall average interest in male nail care and nail art was 3.76, which fell between "average" and "yes". Women showed higher interest in male nail care than men did. While there was no statistically significant difference in the average value, interest in male nail care and nail art was higher among those in their 30s than those in their 20s. Unmarried individuals showed more interest in male nail care than married ones, and higher levels of education were associated with higher interest. In terms of occupation, service workers showed the highest interest in male nail care and nail art. In conclusion, the findings suggest the need for marketing research that caters to the development of services and programs targeting the male nail industry. The study also highlights the importance of segmenting and differentiating marketing strategies that target male and female customers with a high interest in male nail care and nail art. Based on these findings, this study aims to provide direction for the male nail care industry and serve as a basis for the development of customized programs. Additionally, it aims to provide basic data to aid in the development of the nail industry in Gyeongnam.

This paper proposes a new algorithm of clustering similar nodes defined as nodes having similar characteristic values in pure P2P environment. To compare similarity between nodes, we introduce a fitness function whose return value depends only on the two nodes' characteristic values. The higher the return value is, the more similar the two nodes are. We propose a GORGFM algorithm newly in conjunction with the fitness function to recommend and exchange nodes' characteristic values for an interest group formation and maintenance. With the GORGFM algorithm, the interest groups are formed dynamically based on the similarity of users, and all nodes will highly satisfy with the information recommended and received from nodes of the interest group. To evaluate of performance of the GORGFM algorithm, we simulated a matching rate by the total number of nodes of network and the number of iterations of the algorithm to find similar nodes accurately. The result shows that the matching rate is highly accurate. The GORGFM algorithm proposed in this paper is highly flexible to be applied for any searching system on the web.

The purpose of this study was to determine the optimum chemical composition, color value, salinity, pH, total acidity, and texture for the production of short-term Green Gochujang using Cheongyang pepper powder and Meju powder. The results were as follows. The moisture content for Green Gochujang made from Cheongyang pepper powder was 33.50% for CON, and 27.21% for GG1. Crude fat and crude protein contents increased as the amount of added Meju powder increased (p<0.001). GG1 and CON contained 9.47% and 9.05% crude ash contents. Water activity was between 0.89 to 0.90. A higher amount of added Meju powder resulted in an increased color L value (p<0.001). CON showed the highest a value and b value compared to GG4, which had the lowest a and b values. Salinity was between 5.10% to 5.83%, which was lower compared to a former study. CON had a pH of 5.25, and GG4 had a pH of 6.06. Regarding total acidity, CON had a total acidity of 0.85, and GG4 had a total acidity of 0.44. Hardness value was highest in GG1 (1535.63), and lowest in CON (422.07) (p<0.001). GG1 showed the highest value in the adhesiveness property test, whereas CON showed the lowest value. GG1, which contained the highest amount of Cheongyang pepper powder showed the highest gumminess value (698.47). In an acceptance test, CON and GG3 showed the best appearance and scent value. GG3 received the highest interest in taste, texture, and overall quality. Through these results, GG3 made with 150 g of Chengyang Green pepper powder, 200 g of Meju powder, 600 g of starch syrup, 500 g of water, and 75 g of salt showed fine overall sensory interest, and therefore can be used for the production of fine Green Gochujang and Gochujang sauce.

This paper investigates the effects of inflation on real estate prices, particularly the discrepancy between the sales and chonsei prices of housing, in an economy in which real interest rates are secularly declining due to the fall in capital productivity. When real interest rates fall, real estate prices rise relative to chonsei prices, and thus the well-known adverse effect of inflation, or the discrepancy between the value of financial assets (or chonsei principal) and the value of real assets (or real estate), is aggravated although the monetary authority maintains the same rate of inflation. This theoretical prediction can help explain the trend of the ratio of apartment sales prices to chonsei prices. That is, the stabilization of inflation relative to real interest rates appears to have contributed to the secular stabilization of this ratio in the 1990s, while the fall in real interest rates appears to have led to the rise of this ratio since 2001.

This research investigated the purchasing behaviors of fur clothing consumers to verify fur clothing consumption and to establish marketing strategies for the fur clothing market. Since fur clothing has clear characteristics distinguishing it from other clothes, there are many differences in customers' interest. Therefore, it is needed to identify some differences in the customers' interest by their own buying habits. A survey was conducted with a questionnaire and revised by using a theoretical background. Questionnaires were given to 322 ladies in their over 20s. SPSS 12.0 was used to analyse the result with analysis of frequency, a primary factor, crossing, cluster and ANOVA. There were several results as follows. First, purchase behaviors of fur clothing were significantly different between groups divided by demographic variables such as marital status, age, and income level of household. Second, factor analysis on sought clothing benefits resulted in 4 dimensions such as symbolic value, brand value, economical value and practical value. Cluster analysis on the 4 factors of clothing benefits being sought resulted in 3 groups such as one group pursuing symbolism, one group pursuing practicism/economism and a group pursuing brand. Third, purchase behaviors of fur clothing and demographic variables were significantly different between the groups divided by clothing benefits being sought.
