Hollow fiber membranes with chemical and thermal resistances were preapared via themally-induced phase separation process followed by stretching process from the semicrystalline polymers. Isotactic polypropylene was selected as a membrane material and soybeam oil was as a diluent. Various operating parameters were examined in terms of their effects on the structure variation of the membrane, and were optimized. Melt viscosity of polymer-diluent solution influenced stretching of the membrane to affect the porosity and pore size of membrane. Lower coagulation bath temperature accelerated the formation of spherulite, and more stretching was performed. Draw ratio directly affected the stretching of the membrane and membrane prepared at higher draw ratio showed the higher flux and bigger pore size.

The practice of oral surgery or other dentistry possesses the danger of causing the loss of foreign bodies used within the oral cavity. If such foreign bodies would be lost, they could enter the viscera through the esophagus or tracheobroncheal tree. Ingestion is four times as frequent as aspiration and 80% to 90% of ingested foreign bodies will pass through the body spontaneously. Once the aspiration or ingestion of foreign bodies is happened, a dental procedure should be discontinued immediately. If symptoms of respiratory distress, including coughing, wheezing, or stridor, are present, a patent airway should be maintained, oxygen administered, and ventilation supported if necessary. The PA chest radiograph will identify the objects in the lung, esophagus, or stomach. Ingested gastrointestinal foreign bodies may be managed by observation, endoscopy, and or surgical intervention and aspirated tracheobroncheal foreign bodies may be managed by bronchoscopy, and or surgical intervention. This case report describes the management of ingested or aspirated foreign bodies happened to the three patients during intraoral treatment. we recommend that the preventive method of ingestion or aspiration of the dental foreign bodies should be performed prior to intraoraltreatment and the immedieate measures should be carried out after ingestion or asipiration of it.

Currently, as mordants, heavy metals are being used in dyeing process in order to improve dye uptake and dye fastness. These chemicals, however, are mostly harmful to human body and the environment along with the pollution by effluent. Traditionally, rice straw ash solution, lime, etc. have been used as mordants in order to improve the effects on dye uptake and color fastness of dyestuffs. The study of natural mordants would, therefore, be vital to the development and succession of our traditional dyeing methods. In this study, as a preliminary step toward the use of rice straw ash solution for the nautral dyeing using Caesalpinia sappan, several aluminum compounds were employed as mordants. When the purified aluminum compounds were used, on the basis of unmordanted cotton fabric, the WS values of the pre-mordanted and simultaneously mordanted fabrics increased by 2 or 3 times, while those of the post-mordanted fabrics decreased.

Objectives: The purpose of this study was to identify the influence of equality perception and organizational commitment on turnover intention of jobs among psychiatric hospital nurses. Method: Data were collected by questionnaire survey among 158 nurses working in 10 psychiatric hospitals from August 1st to September 30th. 2004. Results: The degree of turnover intention of jobs was significantly different by marital status, religion, qualification of psychiatric specialized nursing, monthly income and the location of hospitals. The correlation analysis showed that the turnover intention of jobs decreased as the equality perception and the organizational commitment increased. The hierachical multiple regression analysis showed that significantly related variables with turnover intention of jobs were religion, monthly income, equality perception and organizational commitment. The model explanation power was 53.1%. Conclusion: Because the equality perception explained 53.1% of variance of turnover intention among psychiatric nurses and organizational commitment was related with the turnover intention of nurses at psychiatric hospitals, activation strategy of organization must include the promotion strategy of equality perception and organizational commitment to decrease turnover intention of jobs among nurses.

저자들은 폐결핵 추정하에 치료를 받았던 Sarcoidosis 환자 1례를 경험했기에 문헌적 고찰과 함께 보고하는 바이다. Sarcoidosis is a granulomatous disease of unknown etiology In which pulmonary manifestations typically predominate with protean extrapulmonary and systemic manifestations. In sarcoidosis, pulmonary symptoms include dyspnea on exertion, non-productive cough and wheezing. Typical radiologic finding is a diffuse infiltration with or without bilateral symmetric hilar lymphadenopathy. Sarcoidosis should be differentiated with pulmonary tuberculosis because of its clincal and radiological slmilarity in Korea, an endemic area of pulmonary tuberculosis. We report a case of sarcoidosis patient whose symptoms were not improved by treatment with anti-tuberculous medication, but by steroid therapy following the diagnosis of sarcoidosis made by biopsy.

의무고용제도 재설계 방안

김종진,장창엽,유완식,김언아,이정주,류정진,강필수,최종철,남용현,김윤삼 한국장애인고용촉진공단 고용개발원 2008 연구개발 Vol.- No.2

현행 우리나라 의무고용제도는 장애인구의 급격한 증가, 장애인차별금지 및 권리구제 등에 관한 법률의 도입 등 외부환경변화에 신축적으로 대처하지 못하고, 경증장애인 중심으로 의무고용제도가 운영됨으로써 중증장애인의 고용배제가 우려되고 있다. 본 보고서는 이러한 문제점을 해결하기 위해 의무고용제도의 일자리 확대와 고용증가를 통해 중증장애인의 고용기회를 확대할 수 있는 정책방안을 제시하기 위한 것이다. 본 보고서는 (1)의무고용 사업체의 의무고용 산정인원에서 자립장애인 제외 (2)현행 2% 의무고용률을 3%로 상향 조정 (3)사업체가 고용하는 중증장애인에 대한 더블카운트(2배) 가산제도 도입 (4)의무고용률 미달 사업주에 대한 부담금 차등징수의 4가지 정책방안, 제도 합리화 차원에서 장려금 지급방식의 개선과 사업주의 장애인에 대한 인식개선 방안을 제시하였다. 정책방안에 대한 영향분석 결과 의무고용 적용대상자에서 비장애인과 고용상 차별되지 않는 자립장애인(6등급)을 의무고용 산정인원에서 제외하는 경우 의무고용 사업체의 고용인원은 23,296명이 감소해 고용률은 1.35%에서 0.88%로 감소하였고, 의무고용 사업체의 장애인 일자리 수는 미고용인원의 증가로 15,152개가 증가하였다. 그리고 기금은 부담금이 631억원 증가하고, 장려금이 352억원 감소해 983억원의 수지개선 효과가 발생하는 것으로 나타났다. 의무고용 사업주의 의무고용률 3% 인상 방안은 의무고용률 상향 조정에 따른 미고용인원의 증가로 장애인의 일자리 수는 43,101개가 증가하고, 기금은 부담금이 1,709억원 증가하는 반면, 장려금은 293억원이 감소해 2,002억원의 수지개선 효과가 발생하는 것으로 나타났다. 의무고용 사업주가 고용하는 중증장애인을 2인으로 더블카운트 하는 중증장애인 가산제도의 도입은 의무고용 사업체의 장애인근로자가 67,261명에서 79,685명(1,2등급만 포함시 75,685명)으로 증가하여 고용률은 1.35%에서 1.60%(1.2등급만 포함시 1.52%)로 증가하고, 의무고용률 미달 사업체의 미고용 인원이 감소하여 2,745개의 일자리가 감소하였다. 그리고 기금은 부담금이 118억원 감소하는 반면, 장려금은 418억원이 증가해 536억원의 수지악화가 발생하는 것으로 나타났다. 의무고용률 미달 사업체의 고용유인을 위해 고용률 1.0%미만, 1.0-1.5%, 1.6-2.0% 미만에 대해 각각 20%, 10%, 5%의 할증률을 순차적으로 가중하여 부과하는 부담금 차등징수 방안(3차년까지의 효과임)은 1.0% 미만 사업주는 86만원, 1.0-1.5% 사업주는 64만원, 1.6-2.0% 미만 사업주는 58만원의 부담기초액을 부과할 때 고용률은 1.35%에서 1.53%로 증가(1.6-2.0% 미만 사업주는 의무고용률 2%를 달성)하고, 미고용인원의 감소로 장애인의 일자리는 8,836개가 감소하는 것으로 나타났다. 그리고 기금은 부담금이 58억원 감소하여 수지는 악화되었다. 이상의 네 가지 방안은 모두 장애인의 고용증대를 가져온다는 측면에서는 유효하지만, 장애인의 일자리 확대를 통한 중증장애인의 고용을 증대한다는 정책목표를 달성하는 데에는 한계점을 안고 있기 때문에 어느 한 정책만을 선택하기보다는 정책효과를 극대화하기 위해 정책결합(policy mix)을 이용하는 것이 바람직함을 제시해주었다. 즉, 의무고용 적용대상자 조정방안/의무고용률 상향조정 방안과 중증장애인 가산제도/부담금 차등징수 방안을 조합 또는 모두 동시에 선택하는 경우 의무고용 사업체의 장애인 일자리 수의 확대와 중증장애인 고용을 동시에 달성하고, 기금의 수지균형도 달성 가능한 것으로 나타났다. The mandatory employment quota system of Korea does not reflect the changing external factors such as the growing population of people with disabilities(PWDs) and the enactment of the Anti-discrimination Law for People with Disabilities. The current employment quota system focuses on people with mild disabilities thus excluding people with severe disabilities from employment. The purpose of this report is to propose a plan in order to increase employment opportunity for the severely disabled through the reform of the employment quota system. This report analyzes the following : (1) exclude grade 6 disability from mandatory employment quota (2) raise the employment quota from 2% to 3% (3) implement the double counting for employers that employ the severely disabled (4) differentiate the amount of levy collected from corporations that are unable to meet the quota. The aforementioned plans are useful in that they increase employment for people with disabilities. However, there are limitation to reaching the policy objectives by increasing jobs for people with severe disabilities. Therefore, to maximize the effects we should consider policy mix of these four policies. In other words, by mixing the policies of adjusting the employment quota target/raising the quota ratio and implementing the double count/differentiating the amount of levy, we can achieve the goal of increasing jobs for the severely disabled and maintain equilibrium between incomings and outcomings.
