This study has focused on geomorphological landscape resources analysis at the Dong-gang River Ecological and Landscape Conservation Area through literature review and field survey. Some appropriate maps have been created for this study. This study intends to examine the distribution characteristics of geomorphological landscape resources at the Dong-gang River Ecological and Landscape Conservation Area, and suggests a solution to manage and maintain the resources. The result has shown that the resources can be divided into four categories : The Dong-gang`s riverside geomorphological landscape resources, Pyeongchang-gun Hantan-ri`s plateau and karst area, limestone caves in various sizes throughout the entire study area, and the mountainous regions close to the study area boundaries. The study concluded that these geomorphological landscape resources are partially damaged or likely to be damaged due to tourist inflow and also the quality of resident lives needs to be improved. Therefore, limiting the number of tourists entering the area or installing guides who provide information about the academic importance of such resources are necessary in terms of maintenance. There is also a need for a customized solution according to geomorphological landscape resources in order to secure benefits for the residents as well.

During the condylar shaving procedure, the articular soft tissue cover can be removed. Author compaired the histological healing process of the articular soft tissue cover between the preservative and unpreservative group group with 45 New Zealand rabbits(Average wt. : about 2.5kg). In unpreservative group, the usual high condylar shave with the removal of soft tissue cover was performed. In the preservative group, the underlying bone, replaced in its original position and sutured. The animals were sacrified 1, 2, 3, 4, 6 weeks interval after operation. The specimens were fixed in 10% neutral formalin and decalcified, paraffin embedded and stained by Hematoxylin & Eosin, and Masson's trichrome. The obtained results were as follows. 1. The condyles of the both group were covered with an articular sop tissue layer. 2. The cartilage cells in subarticular layer has regular continuous patterns in the preservative group but frequently interrupted in the unpreservative group. 3. The incision made in the posterior part of the articular surface for the elevation of the articular soft tissue frequently caused a deformity such as the interruption of the subarticular layer of cartilage. 4. By the above findings, the preservation of articular sop tissue cover may be the effective operation method on concept of bone remodelling.

The crystallinity, crystallite sizes and orientation of hemp fibers treated in caustic soda of various concentration with and without constraint were measured by wide angle X-ray diffraction method. It was found that, 1) The crystallinity monotonously decreased with the increase of caustic soda in the samples treated with constraint, whereas it decreased and again increased with the increase of alkali concentrations in the samples treated without constraint. 2) Crystallite sizes of 002 plane decreased with increase of alkali concentrations, more remarkable decrease occured in the samples treated with constraint, And there were no significant changes on the crystallite sizes of 040 plane in the samples treated with and without constraint. 3) The orientation increased in the samples treated with constraint, whereas it decreased in the samples treated without constraint. The foregoing observations indicate that it is advisible to avoid high alkali concentration and excess tension.

This research was carried out to estimate annual erosion and retreat rates by using datum-point and to identify the characteristics and causes of seasonal variations of sea-cliff slope in Pado-ri, Taean-gun. In the result, the erosion and retreat rates of sea-cliff were increased from spring to summer. The rates were increased rapidly between August and October, caused by the effects of extreme weather events such as severe rainstorms and typhoons, etc. Since then, the erosion and retreat rates of sea-cliff were decreased gradually, but the rates were increased again in winter due to the storm surge and mechanical weathering resulting from the repeated freezing and thawing actions of bed rocks. The factors that affect erosion and retreat rates of seacliff include the number of days with antecedent participation and daily maximum wave height. In particular, it turned out that the erosion is accelerated by strong wave energy during storm surges and typhoons. The annual erosion and retreat rates of study area for the past two years(from May 2010 to May 2012) were approximately 44∼60cm/yr in condition of differences in geomorphological and geological characteristics at each point. These erosion and retreat rates were found to be higher than results of previous researches. This is caused by coastal erosion forces strengthened by extreme weather events. The erosion and retreat process of sea-cliff in the study area is composed by denudation of onshore areas in addition to marine erosion(wave energy).

후기산업사회 지역복지정책의 발달원인에 관한 이론적 고찰

장동호(Jang Dong-Ho) 한국사회복지학회 2007 한국사회복지학 Vol.59 No.3

최근 지역복지정책의 발달원인을 규명하기 위한 비교사회정책 연구들이 국ㆍ내외적으로 크게 증가하고 있다. 대부분 실증분석에 기초한 이 연구들은 방법론적 측면에서는 더욱 정교해지고 있지만, 이론적으로는 전통적인 거시 복지국가 발달이론의 틀을 그대로 적용하고 있는 상황이다. 그러나 초기산업사회라는 특정 상황을 바탕으로 발전한 복지국가 발달이론들로는 후기산업사회에서 이슈가 되고 있는 지역복지정책의 발달을 이해하는 데 한계가 있을 수 있다. 이러한 시각에서 본 연구는 지역복지정책 비교연구들이 무비판적으로 수용해온 대표적인 복지국가 발달이론들, 즉 산업화이론, 권력자원이론, 그리고 국가중심이론의 적용한계점을 논의한다. 그리고 그에 대한 대안으로서 신사회위험론, 신공공관리론 그리고 정부간 관계론의 이론적 유용성을 검토한다. 최종적으로, 지역복지정책 발달의 비교분석을 위한 새로운 이론적 틀을 제시한다. Traditional quantitative approaches to comparative social policy research in welfare state have mostly focused on cross-national variations in social policy. More recently, they have attempted to account for disparities in the local provision of social policy. However, heavily relying on traditional theories of welfare state development (e.g., industrialism theory, power resource approach, and state-centric thesis), most of them seem to have explained the local variation from a central or national perspective, thereby completely ignoring the local perspective. Furthermore, their theoretical bases have been exclusively derived from the social context of post-war era. In tackling these issues, this study aims at localizing and updating the theoretical framework of local welfare policy in the post-industrial age. The framework provided in this study calls for a shift in the theoretical perspective towards more local and new approaches (e.g., new social risks, new public management and intergovernmental relations).

자활사업 참여자 가구의 재무건전성 분석

장동호(Jang, Dong-Ho),손홍범(Son, Hong-Beom) 한국사회복지학회 2020 한국사회복지학 Vol.72 No.3

지난 10여 년간 빈곤층의 가계 재무역량강화를 위한 프로그램들이 자활사업 현장을 중심으로 확산되고 있다. 하지만, 정작 이들의 가계 재무건전성이 어떠한지를 알려주는 전국단위의 경험적 연구는 없다. 이에 이 연구는 소비자학에서 보편적으로 쓰이는 재무비율 지표를 이용하여 우리나라 자활사업 참여자 가구의 재무건전성을 탐색하였다. 분석자료는 2019년 전국의 자활사업 참여자 1,047명이 참여한 설문조사 결과였으며, 분석에 사용한 재무비율은 가계수지비율, 유동성비율, 총부채상환비율이었다. 주요 분석결과는 다음과 같다. 첫째, 가계수지비율의 가이드라인 1.0 미만과 0.9 미만을 충족한 가구는 각각 68.0%, 45.5%였다. 기혼, 다가구원, 채무불이행, 고학력, 중년 가구주 가구의 가계수지비율이 특히 좋지 않았다. 둘째, 유동성비율의 가이드라인 200% 이상과 300% 이상을 충족한 가구의 비율은 각각 12.4%, 9.0%였다. 평균적으로 모든 집단에서 유동성비율 충족률이 낮은 가운데, 특히 월세거주, 채무불이행, 남성가구주 가구의 유동성비율 충족률이 낮았다. 셋째, 총부채상환율 가이드라인 15% 미만(주택담보대출 제외)과 40% 미만(주택담보대출 포함)을 충족한 가구의 비율은 각각 88.4%와 95.9%였으며, 채무불이행, 이혼, 고학력가구의 총부채상환비율이 상대적으로 나빴다. 이상의 분석결과는 자활연구에서 재무건전성 개념의 적극적 활용, 그리고 자활현장에서 재무역량강화사업, 자산형성지원사업, 채무조정지원 사업의 확대, 자활사업 종사자의 재무역량 강화를 위한 효과적인 교육과정 개발이 필요함을 시사한다. Over the past decade, financial capability building programs for the poor have been spreading in the field of self-sufficiency. However, there has been no empirical study at the national level to describe what their household financial soundness is like. This study analyzed the financial soundness of households in self-sufficiency programs, using financial ratio indicators. The data used in this study were collected in 2019 with a nationwide survey in which 1,047 participants from self-sufficiency programs participated. The main results were as follows. First, 68.0% and 45.5% of the households met the guidelines of 1.0(or below) and 0.9(or below) respectively with the household income-expenditure ratios. The households with married couples, large family members, financial default, and higher education showed the worst ratios. Second, the proportion of households meeting the liquidity ratio guidelines of 200%(or higher) and 300%(or higher) were 12.4% and 9.0%, respectively. Overall, it was found that in all groups, the ratio of liquidity ratios was low, particularly in households with monthly rent, financial default, and male household heads. Third, the proportions of households that met the debt-to-income(DTI) guidelines 15(or below) if mortgage loans were excluded and 40(or below) if mortgage loans were included were 88.4% and 95.9% respectively. The ratios of DTI were especially low among households with financial default, divorce, and higher education. Based on these results mentioned above, this study suggests the wide use of the concept of financial soundness in poverty research, and the expansion of financial capability building, asset building, and debt reduction services, financial capability training for professionals in the field of self-sufficiency.

거주지역의 경제적 특성에 따른 대중의 불평등 인식수준과 빈곤관의 차이 분석

장동호(Jang, Dong-Ho) 한국지역사회복지학회 2011 한국지역사회복지학 Vol.0 No.37

본 연구는 거주지역의 경제적 특성에 따른 우리나라 대중의 불평등 인식수준과 빈곤관의 차이를 분석하였다. 실증분석을 위해 한국복지패널 2차년도 자료인 복지인식 설문조사 결과를 이용하였고, 기술통계와 일원ㆍ이원분산분석 그리고 공분산분석을 수행하였다. 주된 분석 결과는 다음과 같다. 첫째, 거주지역의 소득분배 구조가 불평등할 경우 우리사회에 대한 개인들의 경제적 불평등 인식이 강했다. 둘째, 거주지역에 비해 개인의 소득수준이 크게 낮을 경우에도 경제적 불평등 인식수준이 높았다. 셋째, 거주지역의 소득분배 구조가 불평등할수록 빈곤의 책임을 개인이 아닌 사회에서 찾는 구조주의적 빈곤관이 강했다. 이와 같은 결과들은 분석 대상의 연령, 교육 및 소득수준의 영향을 통제한 상태에서 도출된 것으로서 거주지역의 경제적 특성이 대중의 빈곤 및 불평등 관련 인식에 결정적인 영향을 미치고 있음을 시사한다. This paper investigates whether or not public perception of economic inequality and perspectives on poverty are affected by economic characteristics of residential district. More specifically, the paper examines the effects of individuals" financial status, economic characteristics of residential district and the interaction between the two on the public perception and perspectives, while controlling the influences of major socio-economic characteristics of individuals with ANCOVA. Using Korea Welfare Panel Survey, the major findings are as follows: First, the more the economic inequality of the district, the stronger the perception of economic inequality among residences. Secondly, individuals and districts(i.e., neighborhoods) interact with each other in perceiving economic inequality in society; the low-income group‘s perceived level of economic inequality among is higher in a rich and economically unequalized district than in a poor but economically equalized one. Lastly, economic characteristics of both individuals and districts have a large positive effect on the poverty perspective of individuals. In conclusion, the paper argues that both public perception of economic inequality and poverty perspectives are fundamentally determined by the economic characteristics of residential district; therefore neighborhoods matter.

지자체 복지지출 비교분석에서의 종속변수 문제 검토

장동호 ( Jang Dong Ho ) 한국보건사회연구원 2012 保健社會硏究 Vol.32 No.3

본 연구의 목적은 지자체 복지지출 비교연구에서 종속변수 문제를 확인하고 종속변수 조작의 중요성을 환기시키는 것이다. 이를 위해 한국보건사회연구원의 『복지재정DB』와 행정안전부의 『지방재정연감』을 활용하였고, 지자체의 복지노력을 대표할 수 있는 6개 의 복지지출 관련 종속변수(복지비비율, 1인당복지비, 욕구대비복지비, 수급자대비복지 비, 자체복지사업비율, 자체복지재원비율)를 선정하였으며, 이들 간의 상관관계와 이들 각각에 대한 5개의 독립변수(인구밀도, 영유아비율, 수급자비율, 재정자립도, 지자체 1 인당총지출)의 영향 등을 분석해보았다. 그 결과, 6개의 종속변수들 간에 약한 정적 또 는 강한 부적 상관관계가 상당부분 확인되었다. 또한 종속변수에 따라 각 독립변수의 영향력의 크기, 심지어 방향까지 달라지는 것으로 나타났다. 결론적으로, 이러한 결과들 은 복지지출 차원에서의 지자체 복지노력에 대한 평가와 그것의 결정요인에 대한 이해가 복지지출을 어떻게 정의하느냐에 따라 크게 달라짐을 알려준다. 그리고 각 종속변수 또 는 변수정의의 특성과 문제점에 대한 연구자의 충분한 이해와 세심한 주의를 요구한다. This study aims to identify the dependent variable problem in comparative analysis of municipal social spending and to emphasize the importance of operationally defining dependent variables. For empirical analysis, the author used Social Welfare Expenditure Database (Korea Institute for Health and Social Affairs) and the Local Finance Yearbook` by the Ministry of Public Administration and Security. Relationships were examined between five independent variables (i.e., population density, the ratio of children aged 0-4 years, the ratio of beneficiary of National Basic Livelihood Protection, local self-finance reliance ratio, local revenue per capita), and six dependent variables (i.e., social spending ratio, social spending per capita, social spending per capita on social services, social spending-to-needs ratio, social spending per beneficiary of National Basic Livelihood Protection, the ratio of social spending on municipal own business, and the ratio of municipal own source revenue for social welfare). The empirical results were striking. Some dependent variables had very weak positive or strong negative relationships with the other dependent variables, although in comparative analysis of municipal social spending every dependent variable is equally considered as a positive indicator of welfare effort made by municipal government. The explanatory power of independent variables and even its direction varied significantly from dependent variable to dependent variable. These results indicate that the entire findings of the comparative analysis of municipal social spending are pre-determined by the way of defining dependent variables and thus call attention to this matter.
