서울시의 식품 사막 사례 연구

이누리,김걸 한국도시지리학회 2017 한국도시지리학회지 Vol.20 No.3

All human has the right to take healthy foods. However, there are so many people who cannot have it in the areas called as food deserts or food swamps. They are classified into the social weak including the handicapped, the old and the underclasses. The locational characteristics in food deserts are constructed and differentiated by social and economic situation of nations and regions. The food deserts of the U.S.A., and Australia that have a huge land are usually created in the urban periphery and rural area. In contrast, those of the U. K., Japan, and Korea that have a small land are created in the zone in transition of urban core surroundings or the deprived area of urban periphery. Poverty, declined built environment, and aging are major components of food deserts creation. Seoul has a big potential for a new type of food deserts to be created due to high population density and overwhelming apartment based residential environment in contrast with the case of overseas. This study investigates the potential of food deserts in Seoul and looks into the residents’ fresh food consumption behaviors as two cases of Namyoung-dong categorized as a zone in transition and Deungchon-3 dong categorized as a residential area in the terms of the urban spatial structure of Seoul. 인간은 누구나 건강한 식품을 섭취할 권리를 가진다. 그러나 식품 사막 또는 식품 늪으로 불리는 지역에서는 이러한 권리를 누리지 못하는 상당수가 존재한다. 이들은 장애인·노인·빈곤층 등 사회적 약자에 해당된다. 식품사막은 국가와 지역의 사회·경제적 상황에 따라 입지 특성이 달리 나타난다. 미국과 호주 등의 넓은 국토 면적을가진 국가에서는 도시 외곽이나 농촌 지역에서 주로 일어나는 반면, 영국이나 일본, 한국과 같이 상대적으로 국토면적이 좁은 국가에서는 점이지대나 도시 외곽의 빈곤지역에서 나타난다. 빈곤과 불량한 거주환경을 비롯하여 최근 급속도로 진행된 고령화 등이 식품 사막의 중요한 발생요인이다. 서울의 높은 인구밀도와 아파트 중심의 주거환경은 외국의 사례에서는 나타나지 않는 새로운 유형의 식품 사막을 만들 가능성이 있다. 이 연구에서는 도시공간구조상 점이지대와 도시 외곽의 주거지역에 해당되는 서울시 남영동과 등촌3동 거주민의 신선식품 소비 행태를살펴보고, 서울시의 식품 사막 발생가능성에 대해 고찰한다.

The present study aims to identify the trajectory of changes in self-efficacy in the transition from adolescence to adulthood, and the antecedents influencing the pattern of change. We analyzed the Korea Educational Employment and Employment Panel Survey data by applying the latent growth model. Self-efficacy showed a nonlinear change that decreased and then alleviated over time. The performance-approach goal had a positive effect on the initial value of self-efficacy, a negative effect on the slope, and had no statistically significant effect on the quadratic slope. The performance-avoidance goal had a negative effect on the initial value of self-efficacy, a positive effect on the slope, and no statistically significant effect on the quadratic slope. Finally, external regulation had a negative effect on the initial value of self-efficacy, and no statistically significant effect on the slope and quadratic slope. Implications were discussed based on the findings.

이누리,엄현욱,조현숙 한국화재소방학회 2018 한국화재소방학회논문지 Vol.32 No.3

Extremely fine particles seriously affect people and are becoming a social problem. Conventional methods using the typeof beta ray absorption are difficult to have real-time measurements and miniaturization for the acquisition of fine dust. In thispaper, a light scattering method was used. The sensors were configured internally with semiconductor laser diodes forminiaturization, low cost and lightweight. The use of the FFT method makes it easier to separate fine dust according to sizecompared to conventional light scattering sensors. Bluetooth communication also allows the connection, monitoring and controlof devices using smart phones. 최근 초미세먼지는 사회적 재난으로 간주될만큼 국민건강에 심각하게 영향을 미쳐 사회문제가 되고 있다. 기존의미세먼지 측정 방식은 베타선 흡수방식을 사용하여 실시간 측정 및 소형화가 어려운 단점이 존재한다. 본 논문에서는 광산란 방식을 사용하여 소형화 및 저비용의 센싱 장치를 개발하였다. 광산란 방식을 적용한 센서는 내부에 반도체 레이저 다이오드를 사용하여 구성하였으며, 전압레벨의 신호를 주파수레벨로 변환하여 기존 방식의 한계를 극복하고 미세먼지 입자 크기별 분리가 가능하도록 구현하였다. 또한 개발 시스템은 블루투스 통신으로 스마트폰과 연결하여 미세먼지를 모니터링하고, 장치를 제어할 수 있다.

이누리,김창재,최원석,편무욱,김용일 대한토목학회 2017 KSCE JOURNAL OF CIVIL ENGINEERING Vol.21 No.1

Recently, an increasing interest in the Location-Based Services (LBS) has led to the needs for studies on indoor localization. Therefore, this study aims to propose an image-based indoor localization system, which can improve the practicality and efficiency for wider applications. In order to construct reference imagery database, an optical camera and a 2D laser scanner mounted on a mobile platform were utilized and the data acquired was registered to the real world coordinate system. The localization procedure was then conducted based on Bag of Words (BoW) algorithm which matches the images by evaluating the similarities of the histograms produced from them. In addition, the experiments to verify the optimal system design were carried out. Compared to manual construction, the mobile platform-based data acquisition and location registration can be carried out in an easier manner. The proposed localization method provided more than 80% of localization accuracy for the query images taken in various locations and points of view. The system proposed herein is a practical, efficient, and accurate means of constructing the reference images and determining the location of a user in the indoor environment. It was also found that the size of codebook and the number of reference images should be determined while considering the computational time and the purpose of the application. Reducing the difference of the spatial resolution between the reference and the query images also provided more accurate results.

This study examined the optical properties of nanofilament fabrics prepared from polyethylene terephthalate (PET)/modified-PET sea-island bicomponent fibers using an alkali treatment. The luster and anti-transparency properties of the fabrics before and after the alkali treatment were compared. The illuminance of the alkali-treated fabric relative to the position of an illuminometer was higher than that of untreated fabric, except for an illumination angle of approximately $270^{\circ}$, where much of the light was transmitted through the pores created by the removal of the sea materials. In addition, the alkali-treated fabric exhibited superior anti-transparency properties compared to the untreated fabric. Therefore, the outstanding optical performance of nanofilament fabrics was confirmed.

Skin Barrier Function Is Not Impaired and Kallikrein 7 Gene Polymorphism Is Frequently Observed in Korean X-linked Ichthyosis Patients Diagnosed by Fluorescence in Situ Hybridization and Array Comparative Genomic Hybridization

이누리,윤나영,정민영,김지윤,서성준,왕혜영,이혜영,손영배,최응호 대한의학회 2016 Journal of Korean medical science Vol.31 No.8

X-linked ichthyosis (XLI) is a recessively inherited ichthyosis. Skin barrier function of XLI patients reported in Western countries presented minimally abnormal or normal. Here, we evaluated the skin barrier properties and a skin barrier-related gene mutation in 16 Korean XLI patients who were diagnosed by fluorescence in situ hybridization and array comparative genomic hybridization analysis. Skin barrier properties were measured, cytokine expression levels in the stratum corneum (SC) were evaluated with the tape stripped specimen from skin surface, and a genetic test was done on blood. XLI patients showed significantly lower SC hydration, but normal basal trans-epidermal water loss and skin surface pH as compared to a healthy control group. Histopathology of ichthyosis epidermis showed no acanthosis, and levels of the pro-inflammatory cytokines in the corneal layer did not differ between control and lesional/non-lesional skin of XLI patients. Among the mutations in filaggrin (FLG), kallikrein 7 (KLK7), and SPINK5 genes, the prevalence of KLK7 gene mutations was significantly higher in XLI patients (50%) than in controls (0%), whereas FLG and SPINK5 prevalence was comparable. Korean XLI patients exhibited unimpaired skin barrier function and frequent association with the KLK7 gene polymorphism, which may differentiate them from Western XLI patients.
