0이 팽창된 포아송 회귀모형을 이용한 기부회수 자료의 재분석
김인영,박태규,김병수,Kim, In-Young,Park, Tae-Kyu,Kim, Byung-Soo 한국통계학회 2009 응용통계연구 Vol.22 No.4
Kim et al. (2006) analyzed the donation data surveyed by Voluneteer 21 in year 2002 at South Korea using a Poisson regression based on the mixture of two Poissons and detected significant variables for affecting the number of donations. However, noting the large deviation between the predicted and the actual frequencies of zero, we developed in this note a Poisson regression model based on a distribution in which zero inflated Poisson was added to the mixture of two Poissons. Thus the population distribution is now a mixture of three Poissons in which one component is concentrated on zero mass. We used the EM algorithm for estimating the regression parameters and detected the same variables with Kim et al's for significantly affecting the response. However, we could estimate the proportion of the fixed zero group to be 0.201, which was the characteristic of this model. We also noted that among two significant variables, the income and the volunteer experience(yes, no), the second variable could be utilized as a strategric variable for promoting the donation. 김인영 등 (2006)은 두 개 포아송 분포의 혼합모형에 기초한 회귀모형으로써 2002년 (사)볼런티어 21에서 실시한 설문조사 자료를 분석하여 우리나라 개인들이 기부한 횟수에 영향을 미치는 유의적 변수들을 식별하였다. 본고에서는 김인영 등 (2006)에서도 언급하였듯이 기부횟수 0의 관찰 빈도와 예측 빈도간 차이가 유독 큰 점을 감안하여, 0이 팽창된 포아송(zero inflated Poisson: ZIP)을 기존의 두 개의 포아송 혼합분포에 추가하여 일종의 세 개 포아송 혼합분포 형태로 모집단 분포를 구성하며 동 모형의 회귀모형으로써 기부횟수 자료를 재분석하고자 한다. 회귀계수에 대한 추정은 두 단계 EM 알고리즘으로 이루어 졌고, 유의적 설명 변수의 검색은 김인영 등 (2006)과 같았으나 본 연구에서는 고정된 령(零)군의 비율을 0.201로 추정할 수 있었으며, 두 가지 유의적 설명변수인 소득과 자원봉사 중에서 자원봉사가 기부 횟수를 늘리는 안정적 도구 변수로써 작용할 수 있음을 보고하고 있다.
지속성 휴대용 복막투석(CAPD) 30 예에 관한 임상적 고찰
김인영,박진석,이시래,박요한,양상호,박상은,이승도 대한신장학회 1985 Kidney Research and Clinical Practice Vol.4 No.1
Clinical studies were carried out on the 30 cases of CAPD who had been treated from April 1983 to February 1984. The following results were obtained: 1) Twenty-two cases('73,3%) were male and eight cases(26. 7%) were female, with male to female ratio of 2. 75: 1. The age distribution disclosed the 4th decade in 8 cases(26.7%), Che 5th decade in 8 cases(26. 7%), and the 6th decade in 7 cases (23 3%) Indications for CAPD were: patients desire in 13 cases(43.3%), rural residence in 7 cases(23, 3%), diabetes mellitus in 7 cases(6 .7%) unstable hemodynamic state in 2 cases(6 .7%), and poor vascular access in one case(3 3%). 2) Peritonitis was the most common complicat- ion whose incidence was one episode/patient/4, 8 months. Other complications were bloody effluent in 4 cases, transient outflow obstruction in 3 cases, catheter malposition in 2 cases, catheter exit site infection in one case, leakage of dialysate around catheter in one case, scrotal swelling in one case and hearing difficulty in 3 cases. The peritonitis was manifested by cloudy dialysate effluent in 92.9%, abdominal pain in 85.7%, fever in 28.6%, and presence of more than 100 WBC/cmm in eff- .luent fluid in 100%. The culture positive rate of cffluent was 25. 0% CAPD catheters were removed Jue to persistent peritonitis in two cases, catheter malposition in one case, and inconvenience in one case. 3) In one case, intraperitoneal bleeding and cat- heter obstruction was treated with intraperitoneal urokinase administration, and in another case, poor drainage resulted from catheter displacement due to paralytic ileus was treated by Levine tube dec- ompression, which resulted in good catheter posi- tion and function.
『음향과 분노』의 주인공으로서 퀸틴이 보이는 인식론적 현실 탐색
김인영 서강영문학회 2000 서강영문학 Vol.9 No.-
음향과 분노에서 포크너는 미국 남부의 콤슨가가 겪는 비극적 몰락을 다루고 있다. 여전히 전통적 가치관을 지닌 남부사회가 현대사회의 변화를 맞아 기존의 가치 체계가 흔들리는 것을 보면서 포크너는 이 소설에서 콤슨가의 가족들이 어떻게 고통을 받고 있는가 하는 문제를 보여주고 았다. 뿐만 아니라 새로운 차원에서의 현실 인식 양상도 탐구하고 있다. 다시 말하면 작가는 현실인식에 대한 새로운 접근을 보여 주고 있다.
비무장지대(DMZ)의 평화적 이용방안 고찰 -노무현 정부와 이명박 정부를 중심으로
김인영 평화문제연구소 2008 統一問題硏究 Vol.20 No.1
Since 1953, the year of armistice of the Korean War, DMZ (Demilitarized Zone) has been the area of heavily armed confrontation between South Korea and North Korea. However politicians and scholars have proposed that the area of DMZ should be conserved environmentally and developed in the peaceful purpose. There are recently three proposals to use DMZ in order to increase peace between S. Korea and N. Korea and develop those areas as the industrial parks where two Koreas will cooperate peacefully and economically. The first proposal was to establish a "peace and economic cooperation zone" in the area around the West Sea and agreed between President Roh Moo-hyun and Kim Jong-il, the North Korean leader, during the second inter-Korean summit on Oct. 2-4, 2007. The second is a "DMZ Peace Park Project", proposed by Gyeeonggi Provincial Government and is still in the stage of design. The third proposal, socalled "Nadeul Island Project," was made by Lee Myung-bak, President Candidate of South Korea. The "Nadeul Island" will be built as a special industrial zone, meaning free passage in and out of people, information and capital between the South and North. President Candidate Lee proposed the government designate the area at the mouth of the Han River as an inter-Korean economic enclave. This paper intends to analyse the three recent proposals to use DMZ peacefully and economically in the perspectives of reality, conservation, and procedural democracy. In addition to the three perspectives, the perspectives of global community and practicability should also be considered in the stage of planning the above three projects of DMZ.
