가정폭력 피해여성의 사회적 배제 경험에 대한 현상학적 연구

이희연,박태정 한국여성정책연구원 2010 여성연구 Vol.82 No.-

본 연구는 가정폭력 피해여성들이 경험하는 사회적 배제의 본질을 밝히는 데 목적이 있다. 이를 위해 연구자들은 가정폭력 피해경험이 있는 9명의 여성을 대상으로 심층면접을 실시하였고, 결과분석을 위해 지오르기(Giorgi)의 현상학적 연구방법이 적용되었다. 분석결과, 가정폭력 피해여성들은 전 생애 삶에서 사회적 배제에 노출되어 있었으며 특히 가정폭력상황에서 극도의 사회적 배제를 경험하고 있었다. 그들이 경험해 온 사회적 배제의 본질적 주제는 6가지로서 나타났다. 6가지의 본질적 주제는 [불평등한 부부권력관계], [홀로 견뎌야하는 폭력], [폭력의 악순환, 용서의 딜레마], [가정이라는 폐쇄적 성역], [‘나’를 잃어버린, 예속된 삶], [뿌리 깊은 가부장적 폭력문화]이다. 즉 사회구조적 차원에서 가정폭력 피해여성들은 몰성적 사회와 가부장적 가치관에 의해 조작된 여성성을 강요당한 채, 주류사회의 뿌리깊은 가부장적 사회구조 속에서 심각한 사회적 배제를 경험하여 왔다. 또한 이러한 다차원적인 불이익과 차별속에서 여성의 인격과 주체성이 훼손되는 경험을 하고 있었다. This paper examines how abused women's experience of social exclusion is structured. A research using the qualitative methodology of phenomenology is conducted on abused women's experiences with social exclusion. Nine women who had experiences of domestic violence participated as interviewees. Here, direction for analysis was taken from the specific steps outlined by Giorgi. Data analysis revealed that all of them were living in exposure of social exclusion and great fear for their safety. Battered women's experience of social exclusion was structured as six components : (1) Unequal power relationship (2) To endure domestic violence alone (3) Repeated violence, dilemma of forgiveness (4) Untouchable taboo space : Home. (5) Bounded lives without oneself (6) Deep-seated patriarchism of domestic violence. As those components of social exclusion interacted with domestic violence, abused and battered women were continuously exposed to more severe-ongoing suffering.

지식창출활동의 공간적 집적과 지역간 격차요인 분석

이희연 한국지식재산연구원 2010 지식재산연구 Vol.5 No.1

In the last decade, there has been a widespread interest in knowledge production activities as a new engine of endogenous growth. Also there has been a growing importance of the patent as the index of knowledge production. Much literature suggests that knowledge production activities tend to be spatially concentrated and formed the clusters. The purposes of this paper are to analyze spatial patterns of knowledge production activities in Korea based on a data set of patents from 1981-2008, and to analyze its determinants of regional disparity in 2008. Through this research, it was found that knowledge production activities were unevenly distributed. The Knowledge production activity measured by patent counts is highly concentrated in a limited number of cities. The Capital region accounted for 75% of the total number of patents in the period of 1981-2008, suggesting the existence of a strong concentration of knowledge production activities in Korea. The locations of knowledge production activities by themselves represented a strong spatial positive autocorrelation. The location of knowledge production activities is not free from a spatial context and spillover of knowledge production activities are heavily bounded within geographic limits, forming a spatial cluster. This paper uses the spatial statistical model to explore the determinants of regional disparity of knowledge production activities. From the results of the spatial lag model, it was found that the number of graduate students as an input for knowledge production activities, and the ratio of large-scale establishments have been statistically significant. Also the specialization and the diversity of knowledge-based manufacturing industries have a significant effect on regional knowledge production. Such results give some implications for regional economic development policies 지난 10여년 동안 새로이 내생적 경제성장의 동력으로 지식창출활동에 대한관심이 크게 고조되면서, 지식창출활동을 측정하는 지표로서 특허의 중요성이 더욱 부각되고 있다. 지식창출활동은 공간상에 특정지역으로 집중되거나 클러스터를 형성하는 것으로 분석되고 있다. 본 연구는 1981~2008년 동안 국내 특허데이터를 토대로 하여 지식창출활동의 성장에 따른 공간분포패턴을 분석하였으며, 그러한 분포패턴 형성에 영향을 미친 요인을 분석하는 데 목적을 두었다. 우리나라의 경우 지식창출량의 약 75%가 수도권에 집중되어 있을 정도로 매우 불균등하게 지식창출활동이 이루어지고 있는 것으로 나타났다. 특히 지식창출활동의 공간분포패턴은 매우 높은 정적인 공간적 자기상관을 보이며, 해당 지역의 지식창출은 인접한 주변지역의 영향을 받는 공간적 파급효과가 나타나고 있었다. 공간계량모형을 사용하여 지역간 지식창출활동에 영향을 미친 요인을 추출한 결과대학원 재학생수, 대기업의 비율, 지식기반제조업과 주력기반 제조업의 특화도 및지식기반제조업의 다양성 지수가 유의미하게 나타났다. 이러한 분석결과는 지방의 우수 인력 양성과 대기업 유치를 위한 제반 생활환경을 구축하는 정책이 향후지방의 경제발전을 수립하는 데 있어서 시급함을 시사해준다.

GIS의 공간분석기법을 활용한 서비스업의 입지분석

李喜演 誠信女子大學校 韓國地理硏究所 1996 應用地理 Vol.- No.19

GIS was initially developed as tools for the storage, retrieval, manipulation and display of geographical information. However capabilities for spatial analysis of geographical data have been improved in 1990s. There are advantages to linking statistical methods and mathematical models to the database and display capabilities in a GIS. GIS may be seen as a tool that can assist in the development of location theory through facilitating empirical works. The purpose of this study is to show the possibility of application of spatial analytical function in GIS and to explore how GIS can assist locational analysis of service industries, especially franchised fastfood stores and bank branch offices. This paper is structured in four section. The first section is to extract the locational factors which affect the spatial variations of fastfood stores in Dong districts of Seoul, using statistical analysis(multiple regression analysis). Based on locational factors, the second section is to extract potential locational zones for fastfood stores. In other words, overlay function in GIS is used to extract the potential locational zones, based on the demand and supply side of factors which affecte the location of fastfood stores. It can be identified that over 80% of fastfood stores are located in the potential locational zones. The third section of this paper is to apply location-allocation model which is embedded within network module in Arc/Info to analyze optimal location of bank branch offices in Kangnam-Gu, Seoul. The pattern of optimal locations which are proposed by minimizing total distance model(P-median model) is shown the regular distribution of bank offices over Kangnam-Gu. The actual locational pattern of banks in Kangnam-Gu is similar to the ideal locational. pattern proposed by the function of min-distance in location-allocation models in Arc/Info. However, the location-allocation model embedded in Arc/Info should be improved in order to take into account for various objective functions and constraints in locational problems. In the fourth section, the grid module is used in creating the potential surface mapping of the bank branch offices. The distance-decay function based on the gravity model is applied in computing interaction taking place at a location since the distance between customers and the bank office affects the amount of interaction. Also the use of cell-based demand and supply surfaces can facilitate the substraction of from each other. The resultant surface(demand surface - supply surface) may indicates the new potential locational sites for bank offices. In conclusion, this study shows that the location analysis of service industries may potentially be improved using spatial analytical functions embedded in GIS. There is in need academic research towards the integration of spatial analysis and GIS in geography and regional science.

The purpose of this study are to review the concept of spatial structure, in reflection of the development of geographical thought and to explore dynamic mechanism of changes in spatial structure. The arguments of this paper can be summarized as follows: First, the concept and the meanings of spatial structure have developed several different perspectives based on different geographic thought. Logical positivist approach emphasized on the interaction between spatial structure and the process which produce this structure. In other words, relationship between spatial process and spatial structure is reflexive and crucially casual. On the other hand, structuralist approach regarded spatial structure as a product of social structure and social relations in the mode of production based on the notion that space is a social construct. They argued that the spatial structure are important in the construction, functioning, reproduction and change of societies as a whole and of elements of society. Second, three theories and models which would try to explain the dynamic mechanism of changes in spatial structure were reviewed: Janelle's spatial restructure model, Lee's concentrated spatial dispersion model, and Kim's systematic model for analysis of Korean spatial structure. Third, the dynamic mechanism of changes in spatial structure was explored. The evolution of spatial structure depends on the interdependencies that themselves derive from the spatial interaction pattern. Changes in spatial structure clearly relies on varying characteristics of regions and on interaction between regions including migration, financial flows, diffusion of innovations, political linkages and trade. Spatial interdependence via dynamic interaction is a key concept explaining the change in spatial structure over territorial space that can be found at any point in time. Growth in space implies a change in the relative importance of concentration and dispersion forces over space and through time. These two forces pulling in opposite directions always present. An increase in one set of forces leads to a decline in the importance of the other. Thus, changes in relative weights would represent the evolution of spatial structure.

전이성 위암의 새로운 치료 요법

Despite advances in cancer therapy, gastric cancer has a poor prognosis and high cancer-related mortality. Based on the molecular characteristics of cancer, specific targeted therapies have shown clinical benefits for various tumors. In addition, immunotherapy using immune checkpoint inhibitors has led to a paradigm shift in cancer treatment and shown remarkable results in some solid tumors. Although immunotherapy has been actively applied to gastric cancer, the efficacy is unsatisfactory compared with other solid tumors, such as melanoma and lung cancers. This is because of the complex mechanism of gastric cancer, tumor heterogeneity, heterogeneity among patients, and the absence of appropriate biomarkers to predict response. An effective new cancer treatment strategy that combines targeted therapies and various immunotherapies based on biological markers such as tumor mutation burden and microsatellite instability is urgently needed. Furthermore, customized treatment is necessary to overcome tumor heterogeneity.
