The Weolyu gold-silver deposits at Hwanggan, Chungcheongbukdo, is of a late Cretaceous $(74.24{\pm}1.63Ma)$ epithermal vein-type, and is hosted in the quartz porphyry of late Cretaceous age. Based on mineral paragenetic sequence interpreted from vein structure and mineral assemblages, three stages mineralization were distinguished. A variety of ore minerals occurs including pyrite, sphalerite, chalcopyrite, galena with small amount of electrum, native silver, argentite, pearceite, sb-pearceite, argyrotite. The gangue minerals are quartz, rutile, calcite, apatite, fluorite and rhodochrocite. Wall-rock alteration such as pyritization, chloritization, sericitization, silicification is observed near the quartz veins. Au-Ag minerals were crystallized at middle and late stage of the two mineralization sequences. Results from the analysis of fluid inclusion and thermodynamic calculation indicate that Au-Ag mineral deposits were formed primarily by cooling and dilution of hydrothermal fluids($165{\sim}313^{\circ}C$, 0.4~2.4wt.% equivalent NaCl) with some degree mixing of meteoric water.

Purpose: This descriptive study was to explore the factors relating to Social Physique Anxiety(SPA) in the adolescent girls(N=700). These factors included the biological(level of school[age], period of menstruation, and BMI), the sociocultural(Influence of Mass Media, [IMM], Stereotype of Ideal Female Body[SIFB], type of school, perceived figure, and ideal figure) and the BW control-related factors(experience of bodyweight [BW] control, satisfaction at the result of BW control, and motive of BW control). Method: The sample was 700 girls of the middle and high schools in Jeju-do. The data was collected by the self-reported questionnaire and processed with the SPSS Win 12.0 program. Result: 26% of the variance in SPA was explained by the biological factors(level of school) and the sociocultural factors (perceived figure, ideal figure, type of school, and IMM). SPA, IMM, and SIFB were significantly correlated with each others(r=1,65-2.92, p<.05). The mean SPA scores according to BW control-related factors were significantly different. Conclusion: This results suggest that media education is necessary to reduce or eliminate the adolescent girl's SPA. In addition, SPA needs to be considered as the important concept for the future nursing researches and interventions related to BW control.

In terms of junior high school girls' growth patterns during early adolescence, unlike childhood when relatively balanced growth patterns are found and high school years in which the normal adult body type is almost reached, junior high school girls display imbalanced and rapid growth. In fact, diverse size changes by body part occur with a significant difference among individuals. Therefore, it has been difficult for junior high school students to select their exact size when buying a school uniform. This study attempted to develop winter blouse and skirt patterns reflecting the latest comfortable and active school uniform trends, using middle school girl avatars of various body shapes. Skirt and blouse pattern-drawing methods and margins differed. Based on such results, research prototypes were prepared. Then, virtual wear prospective drawings, clothing pressure, and appearance were assessed by body shape. Skirts were assessed with 22 factors while blouses were analyzed with 25 factors. Then, correlations between skirts and blouses were analyzed. According to the analysis, the reason why the dart & pleats position and margin were rated low was confirmed. In a virtual wear assessment on skirt patterns by body shape, a significant difference was found in all categories except for position of the hip circumference, margin of the hips, width of the skirt, and appropriateness of waist line position. The virtual wear assessment on the blouse patterns by body shape also revealed a significant difference in all categories but fit and shape pf the back part. In blouses, a significant difference was observed around shoulders and waist in type 1 and around the belly in type 2. On the contrary, for skirts, a significant difference was found around the hips and waists in type 1 and type 2. Therefore, these factors should be considered in making blouses and skirts. The above results suggested that skirt and blouse patterns should vary by body shape. It is anticipated that there should be further studies comparing brand-name school uniforms for high school girls and school uniforms by body shape.

The purpose of this study were to identify the effect of thesis-writing activity based project method on the ability of girl's middle school student's self directed learning(SDL) and learning attitude. To achieve above study purpose, the subject of this study were selected 60 from second-grade students of reading club(thesis-writing activities participants 30, non-participants 30), applied a program based project method to experimental group, to carry out a pre-post examined targeting two-group with early making a SDL ability and learning attitude inventory, and the results of the data were analyzed by t-test using the SPSS(Ver. 18). The results were as follows: In the aspect of SDL ability development by thesis-writing activity, the student participant showed somewhat significant differences compared to the non-participants. First, a openess, inner-motivation, autonomy, self-conception of SDL ability was significantly higher than those non-participants. Second, confidence, success expert, attention, effectiveness, affection of learning attitude was significantly higher than those non-participants. These results represent that various programs, which can develop SDL ability and learning attitude, can be provided for youth when they join any thesis-writing activity based project method in general and those programs are also very effective in developing SDL ability and learning attitude of juveniles. Furthermore, It is suggested that thesis-writing activity based project method are a necessary element at the school education fields.

We study the conditions under which a given intuitionistic fuzzy subgroup of a given group can or can not be realized as a union of two proper intuitionistic fuzzy subgroups. Moreover, we provide a simple necessary and sufficient condition for the union of an arbitrary family of intuitionistic fuzzy subgroups to be an intuitionistic fuzzy subgroup. Also we formulate the concept of intuitionistic fuzzy subgroup generated by a given intuitionistic fuzzy set by level subgroups. Furthermore we give characterizations of intuitionistic fuzzy conjugate subgroups and intuitionistic fuzzy characteristic subgroups by their level subgroups. Also we investigate the level subgroups of the homomorphic image of a given intuitionistic fuzzy subgroup.

The purpose of this study was to develop and validate regression models to estimate maximal oxygen uptake (VO₂max) from the 20 m Progressive Shuttle Run Test (20 m PSRT) in Korean middle-school girls aged 13-15 years. The 20 m PSRT and VO₂max were assessed in a sample of 194 participants. The sample was randomly split into validation (n=127) and test-retest reliability (n=99, 32 out of 127 participants also performed validity test) groups. 127 participants performed a graded exercise test (GXT, stationary gas analyser) and the 20 m PSRT (portable gas analyser) once to develop a VO₂max prediction model and to analyze the validity of the modified 20 m PSRT protocol (starting at 7.5 km/h and increasing by 0.5 km/h every 1 min). 99 participants performed the 20 m PSRT twice for test-retest reliability purpose. Mean measured VO₂max (39.2±5.1 ml/kg/min) from the potable gas analyzer was significantly increased from that measured during the GXT from stationary gas analyzer (37.7±5.7 ml/kg/min, p=.001) using the modified 20 m PSRT protocol. But it was a narrow range (1.5 ml/kg/min). The measured VO₂max from the potable and stationary gas analyzers correlated at r=.88(p<.001). Test-retest of the 20 m PSRT yielded comparable results (Laps r=.88 & final speed r=.85). New regression equations were developed from present data to predict VO₂max for middle-school girls: y=.231×Laps-.311×weight(in kg)+46.201 (r=.74, SEE=4.29 ml/kg/min). It is concluded that (a) the modified 20 m PSRT protocol is a valid and reliable test and (b) this equation developed in this study provides valid estimates of VO₂max of Korean middle-school girl aged 13-15 years.

The Purpose of this study is to provide the basic data for the improvement or the contents or clothing curriculum in the 7th technology home economics of middle school. The standard of satisfaction of students' according to the detail domains and the standard of necessity and practical use and learners' patterns of activity task suggested in textbooks were evaluated. The ninth grade 169 boy students and 336 girl students in the national capital region were participated in this survey. According to the survey results, firstly, a dress domain got the highest relative importance(28.56%) while a clothes material domain took the lowest relative importance(8.07%) among various detail domains. Secondly, the standard of satisfaction according to each detail domain fell below the average. Generally girls' satisfaction for teaching was higher than boys'. Thirdly, a clothes material domain showed the lowest necessity for textbook contents according to detail domain and other domains showed above the average. The necessity for textbook contents appeared high for boy students rather than girl students. In addition, boy and girl students did not have interest in content relevance in textbook. Especially, they could not do well and understand experiments and practices in clothing section. Finally, The degree of utilization of the activity task ill textbooks was very low. Among various activity tasks, the learning by discovering and exploring were more utilized than cooperating learning.

This study examined the relationships between clothing values, wearing behaviors and the attitudes toward underwear for female students. A survey of female middle and high school students was conducted. 584 questionnaires, collected from April to May, 2009, were analyzed using descriptive statistics, cross tabulation analysis, t-test, factor analysis, and Pearson's correlation coefficient. Economic and aesthetic value were found to be significantly higher than other clothing values amongst older students while students in coeducational schools regarded aesthetic properties of clothing as being more important (p<.05). Girl students' most pursued attitudes toward underwear was modesty. According to age of students and the type of school they attended there were significant differences in students' underwear wearing behaviors. A high level of correlation between clothing values and attitudes toward underwear was found. Aesthetic value out of the clothing values showed a high correlation with esthetics/sexual attractiveness out of the attitudes toward underwear. Aesthetics/sexual attractiveness out of the attitudes toward underwear was shown to be most influential on underwear wearing behaviors. There would be a necessity for emphasizing the wearing of girdle and slip.
