This study was performed to assess socioeconomic status and physical health status of middle-aged men ($40's{\sim}60's$) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthro-pometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p = 0.000) and most of them decreased according to age in educational levels (p =0.000) and family income (p =0.000), and prevalence of chronic diseases (p =0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in oder males (p =0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%. 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p =0.015). Waist-hip ratio (WHR) increased in older males (p = 0.028) and females (p= 0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.
In this study, we compared demographic anthropometric characteristic, health-related lifestyle and diet behavior among weight control behaviors of 1187 (555 male, 632 female) aged $40{\sim}69yrs$ in Ganghwa country. All the data were analyzed by chi-square test, trend test, student t-test using SPSS 12.0 version at p < 0.05. 'Attempting weight control (loss)' was more in women than that was found in men (36.6% vs 20.7%), and women attempting weight loss most were 40-50 yrs. The reasons of weight loss were 'health problem' and 'health promotion'. Physical activity and diet restriction were commonly employed as weight control methods. Both genders attempting weight loss had a higher education level, BMI, percentage of body fat, waist circumference and physical activity than those not attempting weight control (p < 0.05). In dietary habits like 'meal regularity', 'slow eating' and 'over eating', women attempting weight loss were superior than those who not attempting weight control group (p < 0.05). Eating pattern changes like 'decrease of fats and fatty foods intake', 'vegetable oil usage', 'increase of fruit and vegetables intake', 'decrease of sugar and salt intake' showed significant differences (p < 0.001) between the attempted weight control groups and nonattempted weight control groups. Salt taste was a preference in male non-attempted weight control group, while sour, hot and spicy taste were preference in female attempted weight control group (p < 0.05). Preference for processed foods, fried foods and snack were significant differences (p < 0.05) in women attempted weight control group. Those attempting weight loss tried to improve their eating patterns. However, those attempting weight loss were poorer than the others in health-related lifestyle and eating habit. Therefore, it is necessary to make an effort that improve healthrelated lifestyle and diet behavior in middle aged group.

This research was to develop Taekwondo trunk protector(Hogu) and head protector's sizing systems corresponding the regulations by World Taekwondo Association. These sizing systems were established using 2003-2004 Size Korea anthropometric data. The result can be summarized as follows: According to the analysis of correlation, most measurements had high relationship with weight for Hogu and head girth for head protector. Six sizes(47, 54, 59, 64, 70, 76) for Hogu and 4 sizes(52, 54, 56, 60) for head protector were suggested in this study. Hogu sizes indicate body weights and head protector sizes express head girth measurements. By the comparison between current Hogu sizes and new sizes, the smaller sizes of new Hogu were bigger than current sizes in bust girth, back fastening length, shoulder length. On the other hand, the bigger sizes of new Hogu were larger than current sizes in bust girth, back fastening length, shoulder length. In addition, new Hogu's lengths were shorter than current Hogu in all sizes. The lengths of Neck to collar bone in new Hogu sizes were longer than current Hogu. In case of the head protector, there were no measurements besides outer circumference of helmet in recognized specifications of WTF. Therefore some referable measurements such as head girth, head length, bitragion arc, sagital arc were suggested in new size specification. When helmet sizes were suggested, the thickness of the NBR foam also were considered.
Volcanic rocks including rhyolitic tuff, rhyolite and welded tuff in the Bupyeong silver mine area form a topographic circular structure known as a resurgent caldera. Granitic rocks are emplaced inside and outside area of the circular structure. K-Ar dating and Nd-Sr isotope studies were carried out to invesitigate the origin and petrogenetic evolution of the rhyolitic and granitic magma in the Bupeong silver mine area. Whole rock K-Ar age ranges from 208 to 131 Ma for rhyolitic rocks. Radiometric ages for the granitic rocks are 167.6 Ma for pink feldspar biotite granite from inside granitic pluton of the circular volcanic body, 178.8 Ma for the Kimpo hornblende biotite granite and 111.8 Ma for the Songdo foliated granite from outside granitic plutons of the volcanic body. The radiometric age data indicates that the volcanic activities which are partly overlapped by granite plutonic activities in the Bupyeong mine area had recorded early Jurassic and early Cretaceous in age. Initial Sr and Nd isotopic ratios of the rhyolitic rocks ($^{87}Sr/^{86}Sr$=0.710~0.719 and $^{143}Nd/^{144}Nd$=0.5115~0.5118) are similar to those of granitic rocks ($^{87}Sr/^{86}Sr$=0.709~0.716 and $^{143}Nd/^{144}Nd$=0.5115~0.5116) from inside granite stock. This means that similar source materials of felsic magma responsibles for the Bupyeong volcanic rocks and inside plutonic rocks. Based on the Nd and Sr isotopic compositions, rhyolitic and granitic magmas in the Bupyeong area originated from the partial melting of the old continental crust which has Nd model age ranging from 1500 to 2900 Ma. This is analogous to those of the other Jurassic granitoids in South Korea.

Since the existed Korean Web IR systems generally use boolean system, it is difficult to retrieve the information to be wanted at one time. Also, because of the feature that web documents have the frequent abbreviation and many links, the keyword extraction using the inverted document frequency extracts the improper keywords for adding ambiguous meaning problem. Therefore, users must repeat the modification of the queries until they get the proper information. In this paper, we design and implement the relevance feedback agent system for resolving the above problems. The relevance feedback agent system extracts the proper information in response to user's preferred keywords and stores these keywords in preference DB table. When users retrieve this information later, the relevance feedback agent system will search it adding relevant keywords to user's queries. As a result of this method, the system can reduce the number of modification of user's queries and improve the efficiency of the IR system.
Purpose : The purpose of this study was to examine the effects of a self-efficacy promotion program on obesity in elementary school students. Methods : Forty five obese children from a elementary school were select for an experimental group and 53 obese children from another elementary school were chosen for the control group. Both schools located in Kimpo area. Obesity was defined as children whose age-specific BMI was 85th percentile or higher. Pre and post test were conducted to examine the effects of the self-efficacy promotion program. Chi-square test, t-test, paired t-test were used for analyses. SPSS 10.0 was used. Results : The decrease of BMI was significantly greater in the experimental group than the control group. Students' knowledge about obesity was significantly increased in the experimental group compared to the control group. Self-efficacy score was significantly increased in the experimental group. In addition, self-care behavior score was significantly increased in the experimental group. Therefore, the experimental group showed significant improvement in their knowledge, self-efficacy and self-care behavior compared to the control group. Conclusion : The results of this study suggest that self-efficacy promotion programs may have significant effects on the management of obesity in elementary school children. Thus, the results strengthen further research to develop effective intervention programs focusing on self-efficacy for obesity in elementary school children.
Paper, once known and used only as a medium for printing or handicrafts, is now being used in new fields including artistic clothing, and an environment-friendly material for fashion, while the functionality of its formative characteristics and esthetics have been newly highlighted. On this basis, this study performed a content analysis of paper couture and categorization of types of paper modeling techniques based on 904 paper couture submitted to paper fashion shows, exhibitions and contest exhibits from 2001 to 2013. Analysis results showed that paper textile types were most common at 86.64%, while techniques using laminating, bonding, overlapping or paper as-is represented 62.17%. Expressive techniques in which paper was cut or torn and attached to paper clothing was 11.62%, paper folding was 5.75%, drawing and coloring 4.65%, and finally, paper cutting was 2.65%. Meanwhile, among paper modeling techniques using paper yarn textiles, a paper weaving technique was 6.75%. Moreover, other techniques in which paper modeling techniques or subsidiary clothing was blended were 3.65%, and Dak peeling textiles were 1.33%. Paper paste moulding textiles types represented 1.44%, above all papier $m{\hat{a}}ch{\acute{e}}$ techniques of 0.55% and creasing and holding techniques were 0.88%. Paper is sufficient to express the artists' creativity as well as having qualities as an artistic medium, such as variability through combined use with other materials, variation in form, suitability for reuse of waste paper, and environmental friendliness. Also, various paper modeling techniques can be blended with textiles for a generalized technology that overcomes the limits of paper and textiles.
This study was performed to determine the quality characteristics of Jeung-Pyun with the addition of red ginseng (0, 3, 5, $7\%$) which influences the prevention of atherosclerosis and the decrease of blood glucose levels. The quality characteristics of the sample were estimated in terms of general composition, color difference, volume, expansion, texture profile analysis and sensory evaluation. The water and lipid contents did not show any significant difference among the groups. In the groups with added red ginseng, protein and ash contents, and a and b values were significantly increased while L value (lightness) was significantly decreased (p<0.05). The height of the groups with added red ginseng was significant higher than that of the control group(p<0.05). The value of volume and specific volume were the highest in the group with $3\%$ added red ginseng. The degree of expansion was significantly decreased in the groups with $5\%\;and\;1\%$ added red ginseng (p<0.05). In texture profile analysis, cohesiveness was significantly increased in the groups with $7\%$ added red ginseng (p<0.05). According to sensory evaluation, surface color was a thick color in the groups with added red ginseng but flavor did not differ Taste was very good in the groups with $3\%$ added red ginseng and a bitter taste was very strong in the groups with $5\%\;and\;7\%$ added red ginseng. Appearance and overall quality were highest in the groups with $3\%\;and\;5\%$ added red ginseng (p<0.05). Therefore, Jeung-pyun containing $3\%\;or\;5\%$ red ginseng was most preferable.
This study was conducted to investigate the functional composition and antioxidant activity of Cirsium and Carduus genera based on different parts. Leaves of Cirsium setidens Nakai contained 23.66% protein and seeds of Carduus crispus L contained 25.30% lipid. Extraction yields of Cirsium and Carduus genera were higher in leaves than in any other parts of the plants. Total phenolics and total flavonoid content were abundant in extracts of leaves, steam and root of C. japonicum var. ussuriense, and the flower extract of C. setidens Nakai. Silymarin was not found in extracts of Cirsium and Carduus genera. Acacetin was identified in leaf or flower extracts of C. setidens Nakai, or in leaf and steam extracts of C. pendulum Fisch ex DC. Apigenin was identified in the flower extracts of Cirsium and Carduus genera and constituted 7.16 mg/g in C. japonicum var. ussuriense. Cynarin was present at 5.55 mg/g in the seed extract of C. setidens Nakai, and narirutin represented 19.56 mg/g and, 4.18 mg/g of the seed extracts of C. pendulum Fisch ex DC and, Carduus crispus L, respectively. 2,2-Diphenyl-1-2-picrylhydrazyl (DPPH) radical scavenger activity was higher in flower extracts of C. setidens Nakai than in the other genera. Photochemiluminescence activity was 2.3 nmol in leaves and flower extracts of C. setidens Nakai and flower extract of Carduus crispus L. Flowers and seeds of C. setidens Nakai shoe potential as new functional materials.
In this paper, we have studied the images which have been reconstructed by using combination of images acquired by the variation of operating frequency. When inner images have been reconstructed, they have been superposed by the surface state effect. In this case, the images of the phase object can be enhanced by the contrast of inner images. In this experiment, there are two kinds of specimens, one is a reference block haying 1/4T, 1/2T, 3/4T side drilled holes as main run piping material 111 the steam generator in NPP(Neuclear Power Plant)s and the another is a part of a hemisphere type specimen having about 1-2㎜ distance gap. It has been shown that the two results of defect shapes have better than before in this processing and phase contrast grow about twice. And we have constructed the acoustic microscope by using a quadrature detector that enables to acquire the amplitude and phase of the reflected signal simultaneously Further more ore have studied the reconstruction method of the amplitude and phase images and the enhancement method of the defect images contrast.
