Crocidolite quality control (QC) sampling created by the wet generation method has been validated by validation tests such as the accuracy, precision, and storage tests. For this study we designed and developed a manufacturing apparatus and standard operating procedure for making these QC samples. The most important step in the procedure of making QC samples was the stage eliminating static electricity in asbestos fibers. This static electricity hampers the fibers clog functioning. In accuracy and precision tests by phase contrast microscopy analysis, the difference between the reference values and the studied values was at maximum 17.8%. This satisfies the AIHA proficiency analytical test criteria for asbestos. We could confirm the nearly even distribution of crocidolite fibers on the membrane filter. Also, there was no loss of fibers in the storage test after the one month.

본 연구는 영아교사를 대상으로 보육헌신에 대하여 자아탄력성, 직무스트레스, 보육효능감이 어떠한 인과적인 관계로 영향을 미치는지를 구조방정식모형(SEM) 분석을 통하여 파악하는데 목적을 두었다. 이를 위하여 영아교사 337명을 대상으로 자아탄력성, 직무스트레스, 보육효능감, 보육헌신을 측정하고 수집된 자료는 Pearson의 적률상관분석과 구조방정식모형(SEM) 분석을 통하여 분석되었다. 그 결과 첫째, 영아교사의 보육헌신에 직무스트레스의 경우 직접적으로 부적인 영향을 미치며 보육효능감의 경우 직접적으로 정적인 영향을 미치는 것으로 나타났다. 둘째, 영아교사의 보육헌신에 자아탄력성은 직무스트레스와 보육효능감을 통하여 간접적인 영향을 미치는 것으로 나타났다. 셋째, 영아교사의 보육헌신에 보육효능감은 가장 큰 인과효과가 나타났다. 이러한 결과로써 직무스트레스는 보육헌신을 저하시키는 요인이며 보육효능감은 보육헌신을 강화하게 하는 요인이 됨을 알 수 있으며 이 중 보육효능감은 보육헌신의 가장 중요한 선행요인임을 알 수 있다. 더불어 영아교사의 자아탄력성이 보육헌신에 영향을 미치는 경로에서 직무스트레스와 보육효능감의 매개효과가 확인되어 자아탄력성이 직무스트레스는 완화하게 하고 보육효능감은 높이게 하여 보육헌신을 증진시키는 효과가 있음을 알 수 있다. 이는 영아교사의 보육헌신을 증진하기 위하여 직무스트레스의 감소와 자아탄력성의 증진이 효과적이며 무엇보다 보육효능감 증진의 중요성을 시사한다. This study examined the relationship of ego-resilience, job stress, efficacy of child care and teaching and infant teachers` child care commitment. Data were collected from 337 infant teachers. To collect the data, instruments such as ego-resilience, job stress, efficacy of child care and teaching and child care commitment of infant teachers were used. All research variables were measured using by self-reported questionnaires, and were analyzed Pearson`s correlation and structural equational modeling. The results were as follows: first, infant teacher`s job stress was found to have a direct negative effect on child care commitment and to have a mediating effect between ego-resilience and child care commitment. Second, infant teacher`s efficacy of child care and teaching was to have a direct positive effect on child care commitment and a mediating effect between ego-resilience and child care commitment. Third, infant teachers` ego-resilience was to have an indirect effect on infant teachers` child care commitment through job stress and efficacy of child care and teaching. Additionally, infant teachers` efficacy of child care and teaching was to be the most important variable predicting child care commitment. These results suggest that improving infant teachers` efficacy of child care and teaching and ego-resilience and reducing job stress could help facilitate child care commitment and subsequently the quality of child care and early childhood education.

수산물 가공 부산물로 여겨지는 미더덕 껍질을 소재로 한 식품을 개발하기 위하여 건조한 미더덕 껍질에 물을 가하여 끓인 추출물을 얻은 후, 이를 이용하여 미더덕 껍질 추출물 함유 곤약을 제조하였다. 미더덕 껍질 추출물은 농도가 증가할수록 ABTS 라디칼 소거능이 증가한 것으로 보아 항산화능을 보유하고 있었다. 미더덕 껍질 추출물 함유 곤약의 색도는 미더덕 껍질 추출물의 함량이 증가할수록 L값은 감소하지만 a값과 b값은 증가하였고, 갈색도도 증가하는 경향을 보였다. 또한, 미더덕 껍질 추출물의 함량이 증가할수록 곤약의 강도와 경도가 증가하였으며, 절곡검사 결과 모든 곤약에서 유연성과 탄력성이 우수하였다. 관능검사 결과, 맛과 향은 농도가 높아질수록 미더덕 특유의 맛과 향이 높게 나타났으며, 질감과 촉촉한 정도는 대조군을 포함한 모든 곤약에서 유의차를 보이지 않았고, 전체적인 선호도는 25% 농도의 미더덕 껍질 추출물을 함유한 곤약에서 가장 높았다. 이상의 결과는 적절한 농도의 미더덕 껍질 추출물을 이용하면 기존의 곤약과 비교하여 영양적, 물성적, 관능적으로 소비자들에게 긍정적인 반응을 보일 수 있는 제품이 제조될 수 있음을 시사한다. Styela (S.) clava (Korean name: miduduk) tunic is produced as a by-product after processing of S. clava. For utilizing this tunic, a konjac containing the tunic extracts was prepared and the qualities evaluated for their color, textural properties, and sensory attributes. The tunic extract was prepared by boiling tunic with water, followed by filtration through filter paper. Significant 2,2"-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activity was found in the tunic extract. Increasing the concentration of tunic extract in the konjac tended to decrease lightness (L) and increase the redness (a) and the yellowness (b) of the konjac. The strength and hardness of the konjac increased with increasing concentrations of the tunic extract. All test samples with a 3 mm thickness had good flexibility and did not break even after 4 times folds. In sensory evaluations, the konjac containing 25% S. clava tunic extracts acquired a relatively higher score. The results suggest that S. clava tunic can be applied to konjac products to improve their quality and functionality.

PURPOSE: This study aims to investigate the status of sexual intelligence, attitude and behavior of the army soldiers and to explore the relationship between sexual intelligence, attitude and behavior. This study focused on sex of the soldiers under the closed situation from the society where not only sex and culture are open, but the sexual values are distorted on the whole. METHODS: In this study, 500 army solders were selected by convenience sampling, currently in the service at the army unit in Daegu and Gwangju. The survey was performed from July to August 2009 with a questionnaire regarding sexual intelligence, attitude and behavior in terms of the sociology of population. The questionnaire was prepared based on the previous study. For analysis of the results, T-test was employed to analyze the difference of sexual intelligence, attitude and behavior according to the general characteristics of each. Also, the correlation between sexual intelligence, attitude and behavior was analyzed by Pearson's correlation. RESULTS: The sexual status of the subjects are calculated as percentage of the total: sexual intelligence is 39.43; sexual attitude 65.01; sexual behavior 55.21. In the level of sexual intelligence, the educational background has a significant difference from the level of sexual intelligence that the subjects think. In the level of sexual attitude, there revealed a significant difference between the rank of subjects and subjective level of sexual attitude realized by own. On the level of sexual behavior, the results reveal a significant difference between experiences having sexual education and the level of the subjective sexual attitude and sexual intelligence. The higher sexual intelligence is, the more desirable and positive sexual attitude was; the more desirable and positive sexual attitude was, The more sexual behavior was open. CONCLUSION: This study indicated that the sexual intelligence is significantly correlated with the sexual attitude while the sexual attitude is significantly correlated with the sexual behavior.
