Backgrounds: Deaths from pesticides poisoning has increased annually, but no studies have been reported. Especially paraquat is suspected to be a major material in pesticide poisoning deaths. In Korea, simple epidemiology of pesticides poisoning is not well known. So, there is no effective method to prevent pesticides poisoning. We tried to investigate the present status of pesticides poisoning with data from Korea National Statistical Office and suggest an effective counterplan. Methods: We analysed death cause data derived from Korean Statistical association, deaths causes being pesticides poisoning in the year 2002. Also, we investigated data from internet, mainly from Korea National Statistical Office home page. Results: Total 2,875 persons died after pesticides poisoning in 2002 year. Average age is 54.2 year, standard deviation being 17.7 year. Many victims (about $41\%$) died during the herbicides' non-necessary period (JanuaryMarch, October-December) Conclusion: Herbicides sale should be restricted only during herbicides' necessary period, and so called a pesticides safety supervisor system shall effectively prevent herbicides poisoning.

Objectives : Official Arisaematis Rhizoma is described only three species, Arisaema amurnse, Arisaema erubescens, and Arisaema heterophyllum, in national Pharmacopoeia. However, other Arisaema species, Arisaema ringens, Arisaema takesimense and Arisaema serratum, also have been distributed as an inauthentic Arisaematis Rhizoma in the herbal market. To develop a reliable molecular authentication method for Arisaematis Rhizoma in species level, we analyzed DNA barcode regions using six Arisaema species. Methods : Thirty-eight samples of six Arisaema plants species (A. amurense, A. amurense f. serratum, A. heterophyllum, A. takesimense, and A. serratum) were collected from different habitate and nucleotide sequences of DNA barcode regions (rDNA-ITS, matK, and rbcL gene) were analyzed after PCR amplification. The species-specific sequences and phylogenetic relations were estimated using entire sequences of three DNA barcodes based on the analysis of ClastalW and UPGMA, respectively. Results : The comparative analysis of DNA barcode sequences were revealed inter-species specific nucleotides to distinguish the medicinal plant of Arisaema Rhizoma in species levels excluding between A. amurense and its subspecies (A. amurense f. serratum) and A. takesimense and A. serratum, respectively. However, we obtained sequence differences enough to discriminate authentic and inauthentic Arisaematis Rhizoma. Therefore, we suggest that these SNP type molecular genetic markers were an reliable method avaliable to identify official herbal medicines. Conclusions : These marker nucleotides could be useful to identify the official herbal medicines by providing definitive information that can identify original medicinal plant and distinguish from inauthentic adulterants and substitutes.

Objectives : Due to the morphological similarity of the pericarp and description of multi-species in National Pharmacopoeia of Korea and China, the Zanthoxylum Pericarpium is difficult to authenticate adulterant in species levels. Therefore, we introduced the sequence analysis of DNA barcode and identification of single nucleotide polymorphism(SNP) to establish a reliable tool for the distinction of Zanthoxylum Pericarpium from its adulterants. Methods : To analyze DNA barcode region, genomic DNA was extracted from twenty-four specimens of authentic Zanthoxylum species and inauthentic adulterant and the individual internal transcribed spacer regions (rDNA-ITS and ITS2) of nuclear ribosomal RNA gene were amplified using ITS1, ITS2-S2F, and ITS4 primer. For identification of species-specific sequences, a comparative analysis was performed using entire DNA barcode sequences. Results : In comparison of four Zanthoxylum ITS2 sequences, we identified 16, 4, 6, and 4 distinct species-specific nucleotides enough to distinguish Z. schinifolium, Z. bungeanum, Z. piperitum, and Z. simulans, respectively. The sequence differences were available genetic marker to discriminate four species. Futhermore, phylogenetic relationship revealed a clear classification between different Zanthoxylum species showing 4 different clusters. These results indicated that comparative analysis of ITS2 DNA barcode was an useful genetic marker to authenticate Zanthoxylum Pericarpium in species levels. Conclusions : The marker nucleotides, enough to distinguish Z. schinifolium, Z. piperitum, Z. bungeanum, and Z. simulans, were obtained at 30 SNP marker nucleotides from ITS2 sequences. These differences could be used to authenticate official Zanthoxylum Pericarpium from its adulterants as well as discriminating each four species.

In this study, performance of R410A(50%R32/50%R125) and HFC32/HFC125 mixture is measured to examine the effect of composition shift of R410A used for various air-conditioners and heat pumps. The composition of HFC32/HFC125 mixture varies from the reference composition of R410A ±10% with 5% interval. Tests carried out in a heat pump bench tester at the evaporation and condensation temperatures of 7/45℃ and -7/41℃ for summer and winter conditions, respectively. Test results show that both the coefficient of performance (COP) and compressor power of the HFC32/HFC125 mixture have the maximum difference of 2.0% as compared to those of R410A. Compressor discharge temperatures of HFC32/HFC125 mixture are increased up to 6.7℃ as compared to that of R410A. The amount of charge for HFC32/HFC125 mixture vary within 5.6% as compared to that of R410A. Overall, performance of R410A is not appreciably affected by the composition shift of ±10% of R32 under both air-conditioning and heat pumping conditions.

복지의식과 자원봉사활동의 관계에 관한 종단연구

김욱진 ( Kim Wook-jin ) 한국사회복지정책학회 2017 사회복지정책 Vol.44 No.4

이 연구의 목적은 정부주도의 공공복지가 민간의 자선활동, 특히 자원봉사참여수준에 미치는 영향을 사회심리학적 관점에서 분석하는 데 있다. 이를 위해 사회복지 및 사회서비스 공급과 관련해 시민 개개인이 갖는 주관적인 복지의식에 초점을 맞춰 공공복지를 측정하였다. 그리고 복지의식의 시간적 변화가 자원봉사참여수준의 변화에 미치는 효과를 종단적 조사방식에 의거하여 분석하였다. 분석자료는 한국복지패널 2, 5, 8, 11차, 총 4개년도 자료에서 확보하였다. 분석방법으로는 시변요인과 시불변요인, 고정효과와 무선효과, 제1수준과 제2수준 자료의 동시추정이 가능한 다층성장모형, 구체적으로 음이항 로그연결함수에 기반한 일반화선형혼합모형을 활용하였다. 분석결과, 정부주도의 공공복지 확대에 대한 긍정적 인식은 자원봉사참여수준에 종단적으로 부정적인 영향을 미치는 것으로 나타났다. 구체적으로, 국가의 복지정책과 관련하여 성장보다 분배중심의 정책을 수립해야 한다고 생각할수록, 빈곤층, 노인, 장애인을 비롯한 취약계층의 생활안정을 위해 정부지출을 늘려야 한다고 생각할수록, 무상교육 및 무상보육 같은 보편적 복지프로그램 실시에 찬성할수록, 그리고 이와 같은 모든 주관적 인식들이 시간이 흘러 이전보다 강화될수록, 해당 개인의 자발적 봉사활동횟수는 줄어들었다. 연구결과를 토대로 구축효과의 사회심리적 부작용을 최소화하는 방안에 대해 논하고 해결책을 모색하였다. 사회심리학적 관점에서 사회복지의 책임주체와 관여수준을 탐색한 이 논문의 연구결과는 사회복지를 둘러싼 공공과 민간의 관계에 대한 우리 이해의 확장에 기여할 것이다. In this study, I investigate the effect of public welfare on private charities, specifically volunteering, from a socio-psychological perspective. To this end, I measure public welfare in terms of welfare consciousness - the citizen’s subjective thinking of social welfare system, including the delivery of social services. Then I analyze the longitudinal effect of welfare consciousness on volunteering. Data come from four waves of the Korea Welfare Panel Data - the 2nd, the 5th, the 8th, and the 11th. With the merged data, I employ a multilevel growth model, specifically generalized linear mixed model with negative binomial logit link function, to estimate time-varying and time-invariant factors, fixed and random effects, and the level-1 and level-2 data simultaneously. Results show that the more favorable toward public welfare, the more negative against volunteering. Specifically, it was found that the more positive for income distribution over economic growth, and the more friendly toward public assistance to the disadvantaged such as the poor, the disabled, and the elderly, and the more acceptable of universal welfare programs such as free education and free child care, the greater people’s level of participation in volunteering. Most importantly, the negative effects worsened over time. Based on the findings, I discuss the negative socio-psychological consequences of crowding out and provide measures to minimize them. I believe that the findings from the study - a study on the accountability and the involvement regarding social welfare - will contribute to broadening our understanding of the public-private relations surrounding social welfare and the supply of social services.

지역의 물리적 · 사회적 환경과 개인의 건강에 관한 연구

김욱진(Kim, Wook-Jin),김태연(Kim, Tae Yeun) 한국지역사회복지학회 2013 한국지역사회복지학 Vol.0 No.46

본 연구의 목적은 지역의 물리적?사회적 환경과 개인의 건강 간의 관계를 살펴보는 데 있다. 자료는 2011년도 서울서베이 원자료, 재해연보, 재난연보, 범죄분석레포트, 도로교통계획기초자료 등을 병합해 구성하였다. 분석 방법으로는 다층구조 자료에 흔히 쓰이는 선형혼합모형을 활용하였다. 분석 결과, 물리적?사회적으로 열악한 거주지에 사는 개인은 거주지 주변의 환경을 부정적으로 지각함으로써 불량한 건강상태를 나타냄이 확인되었다. 본 연구의 조사 결과는 거주지 주변의 물리적?사회적 환경을 개선하려는 지자체의 노력도 중요하지만, 그에 못지않게 개선된 환경에 대한 지역 주민들의 긍정적 인식 역시 건강의 중요한 결정요인이자 매개요인임을 보여준다. This study aims to examine the association between neighborhood physical and social environments and personal health. Data were obtained from various sources including the 2011 Seoul Survey and later merged for analysis. For multi-level analysis, a Linear Mixed Model approach was used. Results indicate that residing in physically and socially stressful environments is significantly positively associated with low self-rated health; the perception of residing in physically and socially stressful environments fully mediates the association between residing in physically and socially stressful environments and poor self-rated health. Findings suggest that while the local government‘s efforts to improve the physical and social conditions within its administrative district are worth pursuing, equally important is the local residents" positive perception of the outcomes from such efforts.
