조건부수급자의 자활사업 참여와 불참간 의사결정 요인분석

이성희,원종욱 한국사회복지정책학회 2004 사회복지정책 Vol.20 No.-

본 연구는 조건부수급자증 자활사업 불참자의 특성을 자활사업 참여자와 비교하여 분석함으로써 어떠한 요인들이 이 두 집단을 구분짓게 마는지 실증적으로 규명하는데 그 목적이 있다. 조건부수급자중 정당한 사유 없이 자활사업에 불참한 사람들의 특성에 대한 과학적인 분석은 자활사업이 안고 있는 참여율 저조 문제에 대한 원인을 이해하고, 향후 성공적인 자활사업 시행을 위한 정책수립에 기초자료가 될 것으로 사료된다. 이를 위해 『2003 자활정책평가와 개선과제 실태조사』 의 자료를 이용하여 조건 부수급자증 자활사업 참여자와 불참자에 대찬 설문분석과 함께 자활사업 참여결정에 영향을 미치는 요인을 계량적으로 분석하였다. 설문분석 결과 자활사업 불참자는 참여자에 비해 상대적으로 남성의 비율이 높고, 연령은 낮고, 동거 가구원수가 많으며, 학력이 높고, 소득수준이 놓으며, 담당공무원이 자신의 소득수준을 정확히 파악하지 못한다고 생각하는 편으로 나타났다. 자활사업 참여결정에 영창을 미치는 요인을 probit model로 추정한 결과 역시 설문분석 결과의 타당성을 뒷받침하였다. 그리고 자활사업 불참자의 소득 추정식을 분석한 결과 수급자 가구가 근근이 생활하는데 필요하다고 생각하는 금액이 클수록, 즉 기본적인 생활수준을 높이고 싶은 욕구가 강할수록 민간 노동시장에서 얻는 소득수준도 높아지는 것으로 나타났다. The main purpose of the study is to identify the differences in socio-economic variables between participants and non-participants of the public self-reliant program. Under the 『Law of the Guaranteeing Basic Livelihood』, those who are physically fit to work, are classified as conditional recipients. One of the condition applied to them is to participate in the public self-reliant program when they can't find job. By analyzing the survey data of 2003, we found out that there are differences in socio-economic variables between two groups. Other things controlled, men are more likely to not to participate in public self-reliant program rather they chose to work in private labor market. Age is another factor influencing decision on participation of the program. The younger recipients are more likely to work in private labor market rather than public self-reliance program. We also found out that those who believe that real incomes are less likely to be revealed by government social workers are more likely to participate private labor market rather than government program. Finally, we predicted income level that non-participants could earn in the private labor market by utilizing Heckman selection model(two-stage). Even though average income of the non-participants' of the public program was about to 420,000 Won the predicted private market income of the total conditional recipients are close to only 200,000 Won. It implies that public self-reliant program is vital source of income for the recipients who possess labor capacity but are unfit to competitive private labor market.

러프집합과 계층적 분류구조를 이용한 데이터마이닝에서 분류지식발견

이철희,최상철 강원대학교 정보통신연구소 2001 정보통신논문지 Vol.5 No.-

This paper deals with simplification of classification rules for data mining and rule bases for control systems, Data mining that extracts useful information from such a large amount of data is one of important issues. There are various ways in classification methodologies for data mining such as the decision trees and neural networks, but the result should be explicit and understandable and the classification rules be short and clear. The rough sets theory is an effective technique in extracting knowledge from incomplete and inconsistent data and provides a good solution for classification and approximation by using various attributes effectively. This paper investigates granularity of knowledge for reasoning of uncertain concepts by using rough set approximations and uses a hierarchical classification structure that is more effective technique for classification by applying core to upper level. The proposed classification methodology makes analysis of an information system easy and generates minimal classification rules.

비선형 시스템 제어를 위한 퍼지 PID 제어기의 설계 및 해석

이철희,김성호 강원대학교 산업기술연구소 2000 産業技術硏究 Vol.20 No.B

Although Fuzzy Logic Controller(FLC) adopted three terms as input gives better performance, FLC is in general composed of two-term control because of the difficulty in the construction of fuzzy rule base. In this paper, a three-term FLC which is similar to PID control but acts as a nonlinear controller is proposed. To reduce the complexity of the rule base design and to increase efficiency. a simplified fuzzy PID control is induced from a hybrid velocity/position type PID algorithm by sharing a common rule base for both fuzzy PI and fuzzy PD parts. It is simple in structure, easy in implementation, and fast in calculation. The phase plane technique is applied to obtain the rule base for fuzzy two-term control and the resultant rule base is Macvicar-Whelan type. And the membership function is a Gaussian function. The frequency response information is used in tuning of the membership functions. Also a tuning strategy for the scaling factors is proposed based on the relationship between PID gain and the scaling factors. Simulation results show better performance and the effectiveness of the proposed method.

Postweaning multisystemic wasting syndrome (PMWS) is a new emerging disease in swine herds world wide, and porcine circovirus type 2 (PCV2) is known as a major cause of PMWS. In this study, the prevalence of PCV2 Rep gene was examined for the serum, nasal swabs and feces collected from 30 heads of piglets affected with PMWS and 10 heads of normal healthy piglets using polymerase chain reaction (PCR). The diagnostic efficiency of the PCR was evaluated for different types of samples. Rep gene of the isolate (PCV2 S1) was then sequenced. In the group of PMWS-affected piglets, the prevalence of PCR-positive were 70.0% in sera, 33.3% in nasal swabs and 0% in feces. In the normal healthy group, the PCR-positive rates of sera, nasal swabs and feces were 30%, 20% and 0%, respectively. Seven piglets (17.5%) out of 40 showed the simultaneously positive results in both of sera and nasal swabs. The nucleotide sequence homology of Rep gene of PCV2 S1 as compared with the reference strain of PCV2 (GenBank accesson no.AF027217) was 99.3%.

Although architects design and equip same floor plan of the internal medicine ward and surgical ward of a hospital, through the ethnographic field study. I discovered that patients and nurses use two spaces quits differently by the curing method. At surgical ward, operating room has a role of main curing place, and word has merely a role of recovering room. On the other hand, at the medical ward, ward itself becomes main curing place. Nurse station of the medical ward becomes more crowed than that of surgical ward. Patients at medical ward are more sensitive psychologically due to long disease history then have trend to keep territory. Surgical ward becomes crowded by equipment like wheelchairs and stretchers. And front corridor of surgical ward becomes exercise field for rehabilitation. For design for user, suggestions of different design guideline through the field study, for distinctively different characteristic of two wards.

종합병원 병동부의 사용자 중심 계획을 위한 현장연구

이희봉,오상희 中央大學校 建設環境硏究所 2002 環境科學硏究 Vol.13 No.2

종합병원 병동부 중 중심적인 내과와 외과는, 서로 동일한 평면의 설계로 지어져 사용되고 있으나, 본 문화인류학에 바탕을 둔 현장연구를 통하여, 치료 성격과 방법이 서로 다른 두 병동은 질적으로 아주 다르게 사용되고 있음을 보여준다. 즉 외과의 주된 치료실은 수술실이며 병실은 반면 회복실의 역할을 하는 반면, 내과의 주 치료장소는 병동이 된다. 간호 스테이션도 내과가 더 붐비게 된다. 또한 내과 환자의 투병으로 인한 예민한 성격에 의하여 영역확보가 강하게 나타나며 외과는 대신 휠체어 같은 보조 도구들이 많기 때문에 병실이 협소해 진다. 또 외과는 병실은 물론 복도 공간이 회복운동 공간화 된다. 현장연구를 통하여 발견한 차별성을 바탕으로 종합병원의 일반병동부의 내과와 외과병동의 차별적 건축 지침을 제안하는 것이 본 논문의 주제이다.
