노숙인 생활시설 종사자와 같은 휴먼 서비스직은 감정노동의 강도가 높으며, 감정노동은 종사자의 소진과 이차외상스트레스에 영향을 미치는 것으로 알려져 있다. 본 연구의 목적은 노숙인 생활시설 종사자의 감정노동이 소진, 이차외상스트레스에 미치는 영향과 보호 요인으로서 슈퍼비전의 조절 효과를 검증하는 것이다. 연구 대상자는 전국32개 노숙인 생활시설 종사자로서, 218명의 자기 보고식 설문조사 결과를 자료 분석에 사용하였다. 위계적 회귀분석을 통한 주요 연구 결과는 다음과 같다. 노숙인 생활시설 종사자의 감정노동은 소진과 이차외상스트레스에 유의미한 영향을 미쳤으며, 슈퍼비전의 조절 효과가 검증되었다. 즉, 슈퍼비전은 노숙인 생활시설 종사자의 감정노동이 소진과 이차외상스트레스에 미치는 영향을 완충하는 것을 알 수 있다. 주요 결과를 토대로 노숙인 생활시설에서 슈퍼비전 체계의 필요성 및 안정적인 운영을 위한 논의를 하였다. Human service workers working at homeless shelters have been known to experience a high level of emotional labor, which could have effect on the burnout and secondary traumatic stress (STS) of them. This study examined (1) emotional labor affecting on the burnout and STS, and (2) the moderating effect of supervision as a protective factor. We collected data from homeless shelter workers (n=218) at 32 agencies using a self-reported paper-pencil survey. Hierarchical regression analysis were conducted to verify the moderating effect of supervision, Major results were as follows. We found a significant effect of emotional labor on the burnout and STS (β=.484, p<.01, β=.544, p<.01) and a significant moderating effect of supervision (β=-.216, p<.01, β=-.103, p<.05). The results suggest that supervision is an important modifiable variable for burnout and STS especially in homeless shelter workers with high level of emotional labor. Based on the results, we discussed the necessity of supervision system and its successful management in homeless shelters.

III급 부정교합을 지닌 6-14세 아동의 중두개저각에 따른 안면두개골의 형태적 특징 : 측두방사선규격사진을 이용한 횡단누년적 연구

최영철,박수배 大韓小兒齒科學會 2000 大韓小兒齒科學會誌 Vol.27 No.1

부정교합의 분류가 치아의 위치적 관계에 의해 구분되면, 동일한 집단에 속하더라도 이들의 안면두개골은 서로 다른 구조적 관계를 지니고 있어 이들을 동일시 할 수 없으며 안면 두개골의 형태적 특징에 의한 분류가 필요하다. 저자는 6-14세사이의 Ⅲ급 부정교합 아동 135명의 측두방사선 규격 사진을 7,9,11,13세의 연령으로 구분한 후, 중두개저각 40.3˚를 기준으로 이보다 작은 집단 (하악전돌효과군)과 큰 집단(하악후퇴효과군)으로 분류하여 각 집단의 안면두개골의 형태적 특징을 횡단 누년적으로 비교 평가하였다. 모집단의 39.3%가 하악전돌효과군으로, 60,7%가 하악후퇴효과군으로 나타났으며, 두개저, 비상악복합체, 상악골 및 하악골의 전후방적 길이 그리고 전안면 높이와 후안면높이 등의 수직적 길이가 하악후퇴효과군에서 크게 나타난 것으로 미루어 Ⅲ급 부정교합 아동의 많은 수가 좁고 긴 얼굴형(leptoprosopic faceform)에서 찾아볼 수 있는 형태적 특징을 많이 지니고 있으며, 두 군간에는 형태적, 구조적인 차이와 함께 시기적으로도 각기 다름 성장양태를 보이는 것으로 가늠된다.. It is well known that there are different craniofacial skeletal groups in the same malocclusion types. The present study was performed to determine morphologic sub-groups in Korean children with Class Ⅲ malocclusions, and to find out morphological differences between subgroups by means of a cross-sectional longitudinal cephalometric study. In this study, 135 children aged 6 to 14 year-old with untreated Class Ⅲ malocclusions were selected. The samples were divided into two groups depending on the angulation of middle cranial fossa(MCF). That is, when the MCF of an individual was measured smaller than 40.3, he/she was tossed into mandibular protrusive-effect group(MREG), while when an individual was measured larger than 40.3, he/she was tossed into mandibular retrusive-effect group(MREG). There after, the grouped samples were divided into 4 age groups (7,9,11 and 13 year-old). Thirty four linear and angular measurements on the tracings of lateral cephaloradiographs were measured, and the morphological characteristics and differences were compared and analysed by means of Wilcoxon test. It was found that Korean children with Class Ⅲ malocclusions were divided into two groups, in which 39.3% were belonged in the MREG and 60.7% were in the MREG. In the MREG, anterior-posterior length of cranial base, nasomaxillary complex, maxilla and mandible were larger than the MREG. And although there wass mo difference in the total length of mandible (Co-Gn), mandibular body length (Go-Gn) was larger in the MREG during the majority of the observed periods. These results would suggest that a majority of the samples, 60.7%, demonstrated many of configurations of craniofacial skeletal relationships that can be found in the leptoprosopic faceform.

A technical refinement for oral commissure reconstruction is presented. The oral commissure has an important role in oral sphincteric function. Once lost, the oral commissure is very difficult to restore and therefore, reconstruction of the oral commissure requires prevention of this function as well as prevention of microstomia. Trauma and tumor excisions are the most frequent reasons that will necessitate reconstruction of the oral commissure. Direct approximation of the wound margins after resection of the corrner of the mouth could easily induce microstmia and difficulty in opening. Thus case presented here deals with distortion of noraml mouth angle and acquired microstomia due to burn and tissue deface following shotgun and explosive wounds. The a mucosal flap approach was used to rehabilitate a natural looking mouth angle showing satisfactory results function and esthetic wise.

Malaria is the world's most important parasitic infection. Although it has been erw5cated from temperate zones including Korea, increasing numbers of travellers visit tropical malarious countries and imported malaria becomes important medical problem in the developed countries. In Korea with increasing travellers to malaria-endemic area, the incidence of imported malaria shows rising tendency same as the developed countries. It becomes important to personal general personal protective measures and chemoprophylaxis to trevellers, when employed in appropriate manner, that can be highly effective in preventing malaria. We recently experienced a case of in Plasmodium vivax malaria with delayed manifestations due to inadequate chemoprophylaxis. A 53-year-old woman with history of trevel to East Africa 4 months ago and chief complaint of fever was diagnosed as tertian malaria. She had irregularly taken prophylatic antimalarial during travel and had not taken it after return but should have taken it at least 4 weeks after return.

고온·알칼리성 cellulase 및 hemicellulase 생성 미생물을 분리할 목적으로 pH 10.3의 PY-CMC배지에서 55℃로 3회 연속 직접배양하여 효소 생성능이 우수한 20여균주를 분리하였고, 그 중에서 2개균주를 최종 선정하여 균학적 성상을 조사한 결과 고온·알칼리성 Bacillus속과 거의 일치하였다. 선정, 동정된 고온·알칼리성 Bacillus sp. F204와 F1020은 α-1, 4-glucose 등에서는 효소 생합성이 왕성하였으나, glucose와 같은 단당류에서는 효소가 전혀 유도되지 않았는데, 이 두 균주는 carbon catabolote repression을 받고 있었다. 2-deoxy glucose는 야생주에서는 강력한 repressor로 작용하였고, 야생주의 catabolite repression을 해제 시키는데 antimetabolite로 작용한다는 것이 밝혀졌다. NTG(500㎍/㎖, 50℃, 20∼60분)와 UV(2분) 처리후 2-DG(20mM)에 직접배양하여 강력한 catabolite repression resistant strain인 M-211과 M-367을 분리하였다. M-211과 M-367은 2-DG를 energy원으로 이용하였으며, glucose에 대하여 CMCase는 1.5%, avicelase 및 xylanase는 약 1.0%까지 저항성을 보였다. 또한 두개의 변이주의 효소 활성은 CMCase 2배, avicelase 1.5배 및 xylanase3배의 증가를 보였으며, 각 효소생합성을 위한 gene expression은 cAMP-independent transcription을 하는 것으로 나타났다. Cellulase and xylanase synthesis of thermophilic alkalophilic Bacillus sp. F204 and F1020 isolated in our lab, were repressed by glucose and induced by compounds structurally related to α-1,4 linkage (avicel cellulose and xylan et. al.). Catabolite repression-resistant mutants were obtained through treatment of NTG(500㎍./㎖), UV(2 min) and enrichment culture in 2-deoxy glucose (20 mM) containing PY-glucose on the wild type strain. T재 catabolite repression resistant mutants were not repressed by glucose and produced cellulase complex and xylansase when in grown in the presence of 1.0% glucose and 30mM 2-DC, which were repressors in wild type. Enzyme production was greater with the mutants (CMCase of 2 times, avicelase of 1.5 times, xylanase of 3 times) than with the wild type strains under various test conditions. T재 mutants M-211 and M-367 were potential catabolite repression resistant mutants and their gene expression was cAMP independent transcription.

The purpose of this experiment is an experimental study on recycling of waste concrete and suggest a possibility of the Recycled Aggregate Concrete after establishing some kinds of experimental properties of concrete. Therefore, this study compared and investigated properties of natural aggregate concrete and recycled aggregate concrete by replacing the ratio of recycled aggregates under the absorptions, compressive strengths and chemical resistances. As the result, the compressive strength and the chemical resistance of Recycled Aggregate Concrete is lower than the natural aggregate concrete. If was concluded that the properties of the recycled aggregates and lower than natural aggregates.
