본 연구는 ‘사회문화적 아픔이 유발한 이동(Sociocultural Illness-induced Displacement, IID)’이라는 새로운 개념을 제시하여, 최근 도시민들이 사회문화적 환경으로부터 아픔을 겪고 치유나 휴식이 될 만한 장소로 떠나는 이동 현상에 주목하였다. 그동안 선행연구에서는 치유가 되는 이동 자체에 중점을 두었지만, 치유가 되기 이전에 사회문화 적으로 아픔을 입고 치유가 될 만한 장소로 떠나는 미시적이고 단기적인 이동과정에 대해서는 상대적으로 관심이 적었다. 그리하여 본 논문은 ‘사회문화적 아픔이 유발한 이동’이라는 개념틀을 통해 “어떻게 사회문화적 아픔이 이동을 유발하는 데 기여하는가?”라는 핵심질문에 답하고자 하였다. 이와 같은 질문에 답하기 위해 본 연구는 치유를 목적으로 서울 한양도성을 걷고 있는 도시민들을 연구대상으로 설정하여 이들에게 어떤 사회문화적 아픔이 있었으며, 그아픔이 유발한 이동 양상이 무엇인지 파악하는데 연구목적이 있었다. 연구 결과, (1) 신체적 아픔을 지닌 도시민들은 생존전략으로서 이동, (2) 진로 스트레스를 가진 도시민들은 생활패턴의 전환으로서 이동, 그리고 (3) 직장 스트레스를 가진 도시민들은 바쁜 일상 속 틈새로의 이동을 하는 것으로 드러났다. 이와 같은 연구결과는 경쟁이 치열한 도시 속에서도 건강하게 살아가고자 하는 인간의 본능이 작용하여 도시민들의 아픔이 이동을 유발하고 있었음을 함축하 였다. : This paper focuses on citizens’ displacement of places for healing and relaxation, which is induced by sociocultural illness. The author proposes a new concept called sociocultural illness-induced displacement (sociocultural IID). The previous studies have looked into therapeutic mobilities, while relatively few have done into micro- and short-term processes of displacement induced by illness before therapeutic mobilities. Therefore, this paper attempts to answer a following research question with a frame of sociocultural IID: “How does sociocultural illness contribute to induce displacement?” The research purpose is to observe the illness of citizens walking along Seoul City Wall for healing, and the patterns of displacement induced by the illness. The research results can be summarized into three patterns of sociocultural IID: (1) displacement of citizens with physical pain as a surviving strategy, (2) displacement of citizens with career stress as a lifestyle shift, and (3) displacement of citizens with work-related stress as moving to niche in busy daily life. These results imply that illness induces displacement by stimulating citizens’ instincts in order to live a healthy life in a competitive city.

치유적 모빌리티로서 서울 한양도성길 걷기

박향기(Hyanggi Park) 대한지리학회 2016 대한지리학회지 Vol.51 No.1

인간의 삶에서 치유는 떼어낼 수 없는 관계에 있다. 최근 치유의 요구가 증가하면서 이를 위한 공간, 장소, 나아가 이동에 대한 지리적 연구가 필요한 시점이다. 본 연구는 서울 한양도성길 낙산구간 걷기를 사례로 걷기의 과정에서 어떠한 치유요소가 작용하며 그 지리적 함의가 무엇인지를 밝히는 데 목적을 두었다. ‘치유적 모빌리티’ 개념과 틀을 바탕으로 181건의 블로그 텍스트를 연구 자료로 활용하였고 치유요소들을 분류한 결과, ‘기상·기후’, ‘걷기·산책’, 그리고 ‘야경’이 주요 요소로 분석되었다. 또한, 치유의 걷기 과정을 주요 요소들을 다룬 블로그 내러티브 분석으로 살펴본 결과, 치유의 장소만들기, 제한요인으로서 시간, 야경 속 사회적 신체라는 지리학적 함의를 찾을 수 있었다. Human life has been inextricably linked with healing. Recently, as the demands of healing are higher, it is more necessary to study spaces, places and mobilities related to healing in geographical studies. This paper draws on a case study of urban peoples walks along Seoul City Wall to explore what healing factors affect the people walking along historical landscapes in urban center and understand geographical implications of the healing process. Based on the concept and analytical lens of ‘therapeutic mobilities’ introduced by Gatrell, this research analyzes texts written on 181 blogs. The results show the main factors that affect their healing are ‘weather·climate’, ‘walk·stroll’, and ‘nightscape’. Futhermore, the blogs’ narratives focusing on these main factors imply healing place-making, time as limiting factor, and the social body within nightscape in the healing process.

마이크로웨이브(MW)는 유전가열에 의한 열적, 비열적 그리고 이온성 전도 효과를 가지며 높은 에너지 효율을 보이므로 유기성 폐기물의 가용화에 대해 효과적인 방법이다. 본 연구는 고형물 함량이 높은 우분을 대상으로 MW를 이용하여 가용화 최적 조건을 도출하고 이를 토대로 MW의 유전가열 특성을 향상시키기 위해 화학적 촉매물질인 H2SO4과 NaCl을 첨가하여 우분의 가용화율과 가용화 방법에 따른 biochemical methane potential (BMP)을 평가하였다. 우분 고형물 농도 12%와 MW 출력 800 W 및 설정온도 40℃ 조건에서 70.5 mg SCODincreased/kJ로 에너지 대비 최대 가용화율을 보여주었으며, 이때의 SCOD 농도는 원시료 대비 53.2% 증가하였다. 가용화 최적 조건에서 화학적 촉매로 H2SO4를 주입하였을 경우 MW 단독 처리 대비 SCOD 농도는 36% 증가하였으며, NaCl을 주입하였을 경우 22.7% 증가하였다. BMP test에서도 우분 원시료 대비 MW를 이용한 가용화는 메탄 생성량이 6.7%, H2SO4를 주입한 MW 가용화는 13.3%, NaCl을 주입한 MW 가용화는 11.3% 증가하였다. 따라서 마이크로웨이브는 우분의 가용화 전처리에 효율적인 수단이며, 마이크로웨이브의 가용화 효율을 높이기 위해서는 화학적 촉매를 이용할 필요가 있다. Microwave (MW) is an effective method for solubilizing organic solids because it has thermal, non-thermal and ionic conduction effects by dielectric heating and high energy efficiency. In this study, we evaluated the application of MW to the solubilization of cattle manure and investigated the solubilization ratio of cattle manure by solid concentration, MW power and target temperature. And H2SO4 and NaCl were added to investigated the effects on the MW-assisted solubilization. Also, we evaluated the solubilization efficiency by biochemical methane potential(BMP) test according to the solubilization conditions. Maximum SCOD increment per energy supply was 70.5 mg SCODincreased/kJ at 12% of the solid concentration, MW power of 800 W and the target temperature of 40℃. And SCOD concentration went up 153.2% compared to the initial concentration. In the MW-assisted solubilization with H2SO4 and NaCl as chemical catalysts, SCOD concentration was increased by 36% and 22.7%, respectively, compared to the result of MW. The methane production was increased by 13.3% and 11.3% with the addition of H2SO4 and NaCl. Therefore, MW is an effective method for solubilization of cattle manure, and it is necessary to use chemical catalysts to increase the solubilzation efficiency.

The Korean Demilitarized Zone has caused not only the spatial division of the Korean Peninsula but also the underdevelopment and the alienation in its adjacent area(the border region) over the past 60 years. However, recently the growing importance of the regions domestically and globally requires more studies in cultural and historical geography on the border region, focusing on the border region of Gyeonggi province. Therefore, this study investigates geographic distribution of cultural relics in Gyeonggi province for the construction of basic spatial data which cultural and historical geographers can utilize. Regional scales are 9 administrative districts : Ongjin-gun, Ganghwa-gun, Gimpo-si, Paju-si, Yeoncheon-gun, Goyang-si, Yangju-si, Dongducheon-si, Pocheon-si. This study gathers data from the surveys of cultural remains distribution maps and HGIS which have been partially performed in each region. In addition, this study describes the geographic characteristic on the regions by understanding the geographic distribution of cultural relics classified as chronological, typological characteristics and designated cultural heritage. The results of this study indicate that the border region of Gyeonggi province is a cultural and historical landscape itself as well as the essential region historically in political, economical, cultural, and military fields. Furthermore, many of the cultural ruins have been damaged due to the Korean war, access difficulty, and development. Thus, it is necessary to optimize heritage geographic information service, diversify contents of the cultural heritage in the border region and introduce advanced exploration techniques for exploring the cultural relics.

Acne vulgaris is a common disease of the pilosebaceous unit. Hyperseborrhea, a follicular colonization by Cutibacterium acnes and a complex inflammatory state are pathogenic factors of acne vulgaris. In the present study we investigated the anti-acne efficacy of Castanea crenata bur extract (CBE) in vitro and searched active compound for mitigating hyperseborrhea. In sebocytes, CBE inhibited the sebum synthesis through downregulation of sterol response element-binding protein-1 and peroxisome proliferator-activated receptor γ expression. CBE also inhibited the 5-alpha reductase activity which is associated with androgen-induced sebum production. Moreover, CBE showed anti-inflammatory effect in C. acnes and free fatty acid-induced inflammatory condition through suppressing Toll-like receptor 2 activity. Anti-inflammatory effect was also observed in keratinocytes via inhibition of NF-κB translocation into nuclei. Finally, we identified the ellagic acid as an active compound for inhibiting sebum production in CBE. These findings suggest that CBE have potential to be a multi-target agent for acne vulgaris and a good source of ellagic acid as an anti-sebum compound.

프로폴리스는 식물에서 채취한 수지에 꿀벌의 분비물이 합쳐져 만들어진 아교성 물질로 세균이나 바이러스로부터 자신을 보호하는 기능을 한다. 본 연구에서는 한국, 중국, 브라질 유래 프로폴리스 추출물의 항산화, 항균, 미백, 항염 활성을 비교하고, 이들 추출물의 화장품소재로서의 응용가능성을 살펴보았다. 플라보노이드, 폴리페놀함량분석과 자유라디칼 소거능 시험을 통해 항산화 활성을 확인한 결과 한국, 중국, 브라질 프로폴리스 추출물 모두 유의한 항산화 효능을 보였다. 피부에 상재하는 미생물에 대한 항균효능을 MIC 시험법을 통해 측정한 결과 C. acnes 균에서 한국 프로폴리스 추출물이 다른 추출물에 비해 우수한 항균력을 보였다(KPE: 62.5 μg/mL, CPE: 250 μg/mL, BPE: 500 μg/mL). 또한, 한국 프로폴리스 추출물은 멜라닌 세포의 멜라닌 생성을 억제하였고, 마우스대식세포에서 리포폴리사카라이드로 유도된 염증인자인 산화질소와 PGE2 생성을 나머지 두 추출물보다 우수하게 억제하였다. 이들 결과를 종합하면 프로폴리스 추출물은 항산화, 항균, 항염 효능소재로 응용될 수 있으며, 특히 항균, 항염, 미백에서 우수한 효능을 보인 한국프로폴리스추출물의 응용가능성이 우수함을 확인할 수 있었다. Propolis is a sticky resinous substance that is formed by the combination of honeybee secretions and resin of plants, which serves to protect from bacteria and viruses. This study aims to evaluate the efficacy of propolis extract from Korea (KPE), China (CPE), and Brazil (BPE) through antioxidant, antibacterial, whitening, and anti-inflammatory tests, and to examine their potential as cosmetic materials. KPE, CPE, and BPE showed significant antioxidant activities on flavonoid/polyphenol content and free radical scavenging activity. The antibacterial effect of propolis on skin flora was determined by measuring the minimal inhibitory concentration (MIC). KPE showed better antibacterial efficacy than CPE and BPE in C. acnes (KPE, CPE, and BPE: (62.5, 250, and 500) μg/mL, respectively). Furthermore, KPE inhibited the melanin synthesis in human epidermal melanocytes and production of nitric oxide and PGE2 induced by lipopolysaccharide (LPS) in mouse macrophages, which showed better than did CPE or BPE. Taken together, the propolis extracts can be applied to antioxidant, antibacterial, and anti-inflammatory ingredient for cosmetics, while KPE showed superior potential in antibacterial, anti-inflammatory, and whitening efficacies.

Due to modern trends with postponing child-bearing and getting worse living environment in women, an ovarian aging increased pregnancy failure and other complications with menopause or premature ovarian failure. Although several theories have been suggested such as mitochondrial malfunction, DNA damage/repair/methylation, caloric restriction, studies regarding ovarian aging-related molecular mechanisms for development of therapeutic methods are insufficient so far. Our objective is to determine molecular pathways of ovarian aging that result in pregnancy failure and other complications in women health to develop treatment strategies. This study is consisted of two parts: in Phase I stage, we analyzed distinct gene expression profile between young and aged mouse ovaries, and in Phase II stage several preferentially expressed genes in both ovaries were selected and analyzed their physiological functions and involved molecular networks related to ovarian aging for development of diagnostic markers and therapeutic methods. Ovaries from 10 week and 11 month-old FVB/NJ female mice with synchronized estrus cycle were collected for this study. A half of each ovary was used for RNA preparation and the other half for histological analysis. Using the Illumina HiSeq 2000 System, preferentially expressed genes were identified. Functional annotation database-based gene-set enrichment analyses and Pathway Studio® were employed to evaluate aging-related molecular networks. These findings were confirmed through qRT-PCR and immunohistochemistry. To validate RNA-Seq data, we examined expression patterns of marker genes (Amh, Bmp15 and Nobox) that were wellknown to be decreased in ovarian aging process. In young or aged ovary, preferentially expressed 876 genes were identified and extracellular matrix (ECM; p<0.001) and chromatin/nucleosome-related (p<0.001) protein-coded genes have the majority in these genes by GOTERM analysis. Amongthem, we selected several candidate genes and confirmed their expression profiles by qRT-PCR and immunohistochemistry followed by molecular network analysis. Regarding molecular interactions in these genes, PathwayStudio® was employed to predict aging-involved molecular networks in mouse ovary. Here we report a couple of candidate molecular networks and medicines (chemicals) for targeting these preferentially expressed genes/proteins. Further analyses are scheduled to produce transgenic animal models and with human ovarian tissues/cell lines.
