The purposes of this study were: 1) to classify and describe causes of producing wasted furniture and household electric appliances by consumers, 2) to identify the influence of variables on causes of producing wasted furniture and household electric appliances and experience of consumer`s recycling behaviors, and 3) to introduce the ways of activating recycling in wasted furniture and household electric appliances which suggested by consumers. 1,132 housewives living in Seoul, Sungnam, and Choongjoo were used as a final sample of the analysis. Data were collected using a self-administered survey. The result of the study indicated the major variable which affects producing wasted furniture and household electric appliances was the perception of recycling. Also, the level of consumers' recycling behavior in furniture and household electric appliances was very low and age and housing type were the major variables which affect consumers' recycling behavior. Finally, the implications and recommendations for consumers, enterprises, and society were suggested.

권오련,이정선,나은심,김훈 한국의료QA학회 2009 한국의료질향상학회지 Vol.15 No.1

문제: 소화기병검사실에서 대장내시경 검사의 부도건수가 최근 월 200명 정도로 예약인원의 16%에 달한다. 이는 본원 외래진료 부도율이 평균 10%인 것과 비교할 때 상당히 높은 결과이므로 대장내시경 예약환자를 대상으로 부도율 관리를 위한 활동이 필요하였다. 목적: 외래 및 입원환자의 부도건수 및 부도환자의 특성을 분석하고, 개선활동을 통하여 대장내시경 검사의 부도율을 줄인다. 의료기관: 서울 아산병원 질 향상 활동: 부도관리를 위한 개선활동으로 SMS 횟수를 2주전, 4일전, 1일전 3회로 변경하고, 내용도 각 시기마다 차별화하였다. 대장내시경 검사 예약을 하고 기다리는 환자를 대상으로 처방일 순, 예약 날짜순서 등 필요한 항목 순으로 볼 수 있는 리스트가 필요하여 예약대기 프로그램을 개발하였고, 처방일로부터 2주 이내 자동예약을 금지하였다.(7월 10일부터 시작) 예약대기명단에 있는 환자를 대상으로 전화로 예약 변경을 하여 2주 이내에는 예약의 빈자리가 없도록 하였다. 미리 부도를 예측하여 추가로 예약하던 방법에서 정원조정을 하여 정원 외 추가 예약을 하지 않았다. 입원환자 일정관리를 위하여 일정관리 프로그램을 개발하여 타과의뢰 회신을 하는 전임의가 직접 날짜를 전산에 입력하여 회신과 동시에 검사실, 담당주치의, 담당 간호사가 모두 일정을 확인할 수 있도록 하였으나 프로그램이 늦어져 9월 12일부터 시행하였다. 개선효과: 부도건수가 개선 전 8주 동안 385건(예약인원 대비 16%) 에서 개선 후 6주의 평가기간 동안 256건(예약인원대비 14.1%)으로 129건이 감소하였으며, 검사 1-2일전 일정 변경 연락 환자 감소 및 검사 비용 수납 환자의 부도건수가 감소하였다. 대장내시경 검사 예약대기 프로그램 운영 및 예약 변경 전화 활동으로 2달씩 기다리던 환자의 예약일을 약 한 달 정도 단축하여 줄 수 있었다. 검사 정원 관리의 결과로 검사 예약 시 예약기준이 명확해지고, 부적절한 예약으로 인한 검사지연 등이 확실히 줄었다. 또한 입원환자 일정관리 프로그램 적용으로 입원환자의 검사일정과 관련된 전화업무는 확실히 줄어들 것으로 예상된다.

Objectives : This study is to investigate the hypothesis that schizophrenic patients have difficulty in inferring mental state of others. Methods : Twenty schizophrenic patients and twenty normal subjects were administered to the Cartoon Task required inferring the character's intention in a given context. Results : The schizophrenic patients showed a statistically significant impairment in the Cartoon Task. Both groups chose the card depicting a frequent everyday action significantly more rather than the similar card to the last picture in each story for wrong answers. Conclusion : These preliminary results suggest that schizophrenia is associated with a specific deficit of the cognitive ability referred to as social cognition, and this deficit can be detected not only in the acute phase as found in previous research studies, but also in remission. Also when subjects fail to appreciate what is going on in the minds of other people, they seem to rely on a socially familiar experience.

The purpose of this study is to substitute water-based painting materials for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters. This study assessed the exposure of organic solvents to the painters using water-based and solvent-based painting materials and compared compositions, painting processes and the health hazards of the application of these alternative painting materials. The results of this study are as follows. 1. solvent-based painting materials used in motor-repairing process consist of various organic solvents, which consist primarily of toluene, xylene, ethyl benzene, ethyl methyl bezene, trimethyl bezene, ethyl acetate, butyl acetate, methyl isobutyl ketone, 2-ethoxy ethanol, 2-ethoxy ethyl acetate and toluene-2.4-diisocianate and the others. These organic solvents are know as health-hazardous substances. But water-based painting materials are high-solid, low-solvent ones and consist of such two organic solvents as 2-butoxy ethanol and 2-heptanone and the others. 2. The painters using solvent-based painting materials in motor-repairing process are exposed to various organic acetate, methyl isobutyl ketone, trimethyl benzene, 2-ethoxy ethanol, and 2-ethoxy ethyl acetate. But the painters using solvent-based ones are only exposed to 2-butoxy ethanol and 2-heptanone. 3. By using water-based painting materials in stead of solvent-based painting materials containing health-hazardous organic solvents, the exposure of such organic solvents in the painter's breathing zone can be largely prevented. 4. This study recommends water-based painting materials as substitutes for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters.

동부(Vigna sinensis King) 자엽에서 α-amylase 활성에 미치는 식물 생장 조절의 효과

權義貞,權五溶 충남대학교 기초과학연구소 1997 忠南科學硏究誌 Vol.24 No.1

The effects of plant growth regulators on α-amylase activities in the embryonic axis-attached and detached cotyledons of Vigna sinensis King have been studied. In the absence of plant growth regulators, α-amylase activities in the embryonic axis-attached and detached cotyledons developing for 3 days have been generally increased, and than gradually decreased. When the 10 ^6M solution of gibberelli acid (GA_3), kinetin, indole-3-acetic acid (IAA), and 2,4-dichlorophenoxyacetic acid (2,4-D), have been exogenously supplied in the detached cotyledons for 3 days, α-amylase activities have occurred with about 2.4-fold in GA_3, 2.8-fold in kinetin, 1.8-fold in IAA, and 3.7-fold in 2,4-D, rather than the control. In the detached cotyledons treated with the 10 ^7M solution of zeatin, and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), α-amylase activities have been orderly increased with about 2-fold in zeatin, and 3.3-fold in 2,4,5-T. Consequently, it has been recently suggested that the 10 ^6M solution of 2,4-D besides the 10 ^7M solution of 2,4,5-T, which is a sort of synthetic auxin, has been obviously induced the development of α-amylase occurred in the embryonic axis-detached cotyledons of Vigna sinensis King.

폐쇄성 수면 무호흡 환자의 측모 두부방사선계측사진 및 치아모형 연구

폐쇄성 수면 무호흡증이란 수면도중 주기적으로 호흡이 멈추는 증상을 말한다. 상악과 하악이 후퇴되어 있거나 하악이 작으며 수평적으로 기도 폭경이 좁고 혀가 후방에 위치하는 등 폐쇄성 수면 무호흡 환자의 전후방적인 악골 및 연조직 특성에 대한 평가는 많았으나 치열 및 악궁에 대한 평가가 부족하여 폐쇄성 수면 무호흡증 환자의 골격적 특징과 악궁의 폭경과 구개깊이와 수면무호흡지수와의 상관관계를 알아보고자 하였다. 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원한 환자 중 수면다원검사와 측모 두부방사선계측사진과 치아모형이 갖추어진 38명의 남자를 대상으로 하여 치아모형과 측모 두부방사선계측사진, 수면무호흡지수와 체질량지수를 비교하였다. 수면무호흡지수와 악궁의 횡폭경, 구개깊이, 수직피개량 및 수평피개량과는 상관관계가 없었으며 수면무호흡군에서 상기도 폭경은 좁고, 하기도 폭경은 넓은 경향이 있었다. 수면무호흡지수와 상기도 폭경은 미약한 음의 상관관계를 가졌으나 하기도 폭경은 미약한 양의 상관관계를 가졌고, 수면무호흡지수가 클수록 하악 하연으로터 설골까지의 거리도 멀었다. To evaluate the cephalometric and dental characteristics of obstructive sleep apnea (OSA) patients, 23 OSA patients and 15 control, non-OSA, patients who visited the Sleep Disorder Clinic Center, Keimyung University were investigated. Patients who suffered from apnea-hypopnea episodes over 10 times per hour were diagnosed as having OSA after polysomnograph testing. Impressions were taken with alginate. Cephalometric radiographs were taken at maximum intercuspation. The dental cast measurements, including transpalatal width, intercanine width, intermolar width and palatal depth did not differ between the control and OAS groups and did not have a positive correlation with the apnea-hypopnea index (AHI). Upper airway width was statistically narrower than the control group. Upper airway width had a low negative correlation with AHI, but, lower airway width had a low positive correlation, and, the higher the AHI score, the longer the mandibular border to hyoid distance.

The study of the herbaceous species association in the larch forest of Mt. Chungkyeu was carried out from April to October, 1980. 1. The herbaceous ground association was consist of 43 species, Oplismenus undulatifolius, Festuca ovina, Oalamagrostis arundinaceae var. brachytricha and Carex pediformis var. rhizina were dominant species. 2. The major herbaceous species, of which important value was above 10, were Oplismenus undulatifolius(28.2%), Festuca ovina(26.7%), Miscanthus purpurascens(26.5%), Calamagrostis arundinaceae var. brachytricha(21.2%), Carex nanella(17.5%), Carex lanceolata(15.4%), Carex pediformis var. rhizina(14.1%), Carex siderosticta(12.7%), Potentilla fragarioides(11.7%) and Artemisia keiskeana(10.5%). 3. Classifying the herbaceous ground association by partial ordination, it was divided into two kinds of association ; Carex-Oplismenus association and Calamagrostis-Oplismenus association. 4. The results of the species association analysis was the same as the ordination. The coefficients of species exhibited the positive value in the same association, on the contrary, it was negative value in the different association.
