The National Institute of Environmental Research (3rd KONEHs) conducted a survey of 280 residents in Ulsan, Suwon and Asan, and the concentration of heavy metals in the blood and urine were also analyzed. In case of blood lead concentration, Ulsan 2.27 ㎍/㎗, Suwon 2.08 ㎍/㎗, and Asan 1.75 ㎍/㎗, the high peak in Ulsan, and the low peak in Asan. In case of cotinine concentration, Ulsan smoking(609.16 ㎍/g_ct) is higher than nonsmoking(74.07 ㎍/g_ct), as Suwon and Asan smoking(416.72 ㎍/g_ct, 903.21 ㎍/g_ct) is higher than nonsmoking(72.72 ㎍/g_ct, 18.06 ㎍/g_ct), smoking group is higher than nonsmoking group in all areas revealed statistically significant correlation(p<0.01). In considering results synthetically, these study results are an aid to constructing environmental health science-side heavy metal management measure education programs for normal residents.

Background: Camellia sinensis L.(CS) is a perennial evergreen species of plant whose leaves are used to produce tea. In this plant species, the parts used are the leaves, sub-branch parts are thrown out. Methods and Results: Ethanol extract of sub-branch parts was used for isolation of major compounds by column chromatography. Structures were identified as caffeine (1), (-)-epicatechin (2) and (-)-epicatechin gallate (3) by interpretation of spectroscopic analysis, including 1H- and 13C-NMR. High-performance liquid chromatography (HPLC) method was used to compare the quantitative level of marker compounds in various extraction solvents of sub-branch parts of CS. The content of caffeine, (-)-epicatechin, and (-)- epicatechin gallate in 30% ethanol extract showed higher value with 3.28 ± 0.57 ㎎/g, 5.53 ± 0.88 ㎎/g, and 1.29 ± 0.24 ㎎/g, respectively. Conclusions: These results indicated that not only leaves parts but also sub-branch, could be a good source for the functional material and pharmaceutical industry.

Purpose: The purpose of this study was to test a 2×2 model of perfectionism among dancers. Methods: Dancers(N=538, male=95, female=443) completed measures of multidimensional perfectionism(self oriented and socially prescribed perfectionism), cognitive appraisals(challenge and threat), emotion regulations(reappraisal and suppression). Results: Moderated hierarchical regression and simple slope analysis indicated that dance majors with pure self oriented perfectionism were related to higher emotion regulation(reappraisal and suppression) than dance majors with non perfectionism. Dance majors of mixed perfectionism were related to higher challenge(cognitive evaluation), emotion regulation(reappraisal and suppression) than dance majors of pure socially prescribed perfectionism. Furthermore, dance majors of were associated with higher levels of threat(cognitive evaluation) than dance majors with pure self oriented perfectionism. Conclusion: The results of this study partially support the predictions of the 2×2 model of perfectionism in dance.

연구의 목적은 교사와 동료의 자율성 지지와 무용전공 중고등학생들의 무용 내적동기의 관계에서 기본 심리적 욕구의 매개효과를 검증하고, 학교급 간 경로 동일성을 비교하는데 있다. 국내의 예술중고등학교에서 무용을 전공하는 425명의 학생들을 대상으로 구조방정식모델과 다집단 분석을 실시하였다. 구조방정식모델 분석의 결과, 교사와 동료의 자율성 지지는 세 가지 기본욕구를 예측하였지만 유능성 욕구만이 교사의 자율성 지지와 내적동기와의 관계를 부분적으로, 동료의 자율성 지지와 내적동기와의 관계를 완전 매개하는 것으로 나타났다. 다집단 분석의 결과, 지각된 동료의 자율성 지지가 자율성 욕구에미치는 영향력은 고등학생보다 중학생에게서 더 강하게 나타났다. 본 결과는 무용 맥락에서 중고등학생들이 지각한 교사와 동료의 자율성 지지는 유능성 욕구만족에, 유능성은 내적동기에 크게 기여하며, 중학생일수록 동료에게 자율성을 지지받을 때 자율성 욕구만족이 더 크다는 사실을 시사한다.
