‘60년대 초부터 도시내 조성된 노후화된 산업단지 및 산업지역의 재정비가 국가적 과제 및 지역현안으로 대두되고 있다. 도시내 산업단지는 도심이라는 지리적 기반을 바탕으로 도시성장을 견인하고, 또한 새로운 미래사회에 부응하는 역할을 수행하기 위한 고부가가치형, 환경친화형 산업단지로의 변화를 요구받고 있다. 이러한 노후 산업단지의 재정비 및 재생의 필요성에도 불구하고 현실적으로 수익성과 복잡한 이해관계 때문에 현 제도 하에서 원활한 재정비 추진이 곤란한 실정이다. 노후산업단지에 대해서 업종구조의 고도화 및 기반시설 재정비 등을 통해 국가 및 지역경쟁력의 제고와 이를 위한 재생차원의 방안이 모색되기 위하여, 먼저 사업시행을 원활히 하기 위한 제도적 뒷받침이 먼저 강구되어야 한다. 따라서 본 연구는 노후 산업단지의 재정비 및 재생을 촉진하기 위한 구체적인 제도적 실행방안을 수립하기 위해 노후산업단지의 재생을 위한 주요 쟁점과제를 도출하고 국내외 선진사례검토를 통해 주요 쟁점과제에 대한 시사점을 제시하고자 한다. Reorganizations of aged industrial park and industrial area that was established in the early 1960s has been issued to the regional level of autonomous government as well as national level for vital economy. The old industrial park in the city has been leading the city development for the past, and are encountered to change the city development adopting the high-value and environment friendly industrial park for the future. Even we are fully understood that the reorganization and regeneration of aged industrial park are needed, the complexity and profitability of the project are not smoothly implemented. Therefore, the plan for the business type advanced of the aged industrial park and improvement of infrastructure will be reviewed and prepared to make the nation and region to have competitive edge for regional development. At the same time, a institutional strategy to implement the project are prepared and supported. This study is to conclude controversial issues on the regeneration of aged industrial park from the domestic and foreign experiences and case studies and suggest some lessons and implementing strategy for the successful regeneration of aged industrial park.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

제3분과 : 야생동물 ; 국립공원 산불통제구간내 야생동물 서식현황 분석 -지리산국립공원 노고단~피아골계곡을 중심으로-

강병선 ( Byung Seon Kahng ),박기연 ( Ki Yeon Park ),김은창 ( Eun Chang Kim ),이재윤 ( Jae Yoon Lee ),지기선 ( Ki Seon Ji ),최형진 ( Hyung Jin Choi ),오현경 ( Hyun Kyung Oh ) 한국환경생태학회 2013 한국환경생태학회 학술대회지 Vol.2013 No.1

우리나라 전 국토의 6.58%를 차지하고 있는 국립공원은 생태계 현황을 대표하는 지역으로 한국에 서식하는 생물종 39,150종 중 40%에 해당하는 15,727종이 서식하고 있다(국립공원관리공단, 2012). 특히 환경부에서 지정한 멸종위기종 221종 중에서 65%에 해당하는 144종이 서식하고 있어 인간의 간섭 및 개발압력으로부터 마지막 피난처의 중요한 역할 또한 수행하고 있다. 국립공원은 자연생태계와 자연 및 문화경관 등을 보전하고 지속가능한 이용을 도모함을 목적으로 하는 자연공원법에 의하여 지정되는 자연공원의 하나로서 자연생태계의 보전뿐만 아니라 지속가능한 이용 또한 고려되어야 한다. 즉, 생물종 서식처의 보존 뿐만 아니라 탐방객의 이용 또한 고려되어야 하며 이를 위해서는 생물종의 서식현황 분석은 반드시 선행되어야 할 과제이다. 그러나 생물종이 다양하고 서식처가 광범위하여 종의 전체적인 서식현황을 분석에는 많은 시간과 비용이 수반된다. 따라서 시간과 공간이 제한되는 산불조심기간 중 산불통제 구간을 대상으로 야생동물의 서식현황을 분석해 보고자 하였다. 아울러 구례군 지역에 서식하는 야생동물의 서식현황을 분석하여 보호지역 관리에 기초자료를 제공하고자 하였다. 월 1회 정기적으로 탐방로를 중심으로 야생동물의 식흔, 배설물 등 흔적을 2010년부터 2012년까지 최근 3년간 모니터링 하였으며, 모니터링 시 GPS 좌표 측점, 사진촬영, 주변환경조사 등을 병행하였다. 아울러 무인센서카메라를 10대 설치하여 실체를 확인하였으며, 조사된 자료는 GIS DB로 최근 3년간, 지리산국립공원 노고단~피아골계곡에서 조사된 야생동물 흔적은 124건으로 삵 59건, 담비 27건, 족제비 21건, 멧토끼 10건, 멧돼지 4건, 고라니 2건, 오소리 1건 등이었다. 이중 삵과 담비는 멸종위기종으로서 86건으로 발견종의 69%를 차지하고 있었다. 특히 봄과 가을철 산불통 제기간 중에는 월평균 19회 관찰되었는데 이는 다른 기간 평균 4회 보다 5배정도 많은 횟수로 탐방객의 출입이 제한되었을 때 위협요인이 감소됨으로서 서식여건이 보다 안정화되어 훨씬 많이 발견되고 있음을 알 수 있었다. 2010년부터 2012년 지리산국립공원 구례지역에서 조사된 야생동물 698건의 서식 분포특성을 분석한 결과 삵 286건, 담비 139건, 족제비 95건, 수달 53건, 오소리 30건, 멧돼지 30건, 멧토끼 29건, 너구리 16건, 고라니 13건, 노루 4건, 하늘다람쥐 3건 등이었다. 특히 멸종위기종인 삵, 담비, 수달, 하늘다람쥐 등이 481건으로 68%를 차지하고 있어 멸종위기 야생동물의 출현빈도가 매우 높음을 알 수 있었다. 최근 3년간 야생동물 서식현황을 분석한 결과 타기간 보다 산불방지기간에 출현빈도가 높아 탐방객의 출입에 따른 위협요인을 계량적으로 파악할 수 있었으며, 특히, 봄철 산불방지기간은 야생동물의 번식기라는 점에서 보다 안정된 서식처를 제공한다는 의의가 있을 수 있다. 또한 멸종위기종의 흔적이 전체종의 68%가 발견됨으로서 멸종위기종의 서식처를 제공하고 있음을 알 수 있었다. 향후 이러한 결과를 바탕으로 각 야생동물에 대한 서식처 분석과 더불어 이를 통한 관리방안이 수립될 필요성이 있다.

Adipose sirtuin 6 drives macrophage polarization toward M2 through IL-4 production and maintains systemic insulin sensitivity in mice and humans

Song, Mi-Young,Kim, Sang Hoon,Ryoo, Ga-Hee,Kim, Mi-Kyung,Cha, Hye-Na,Park, So-Young,Hwang, Hong Pil,Yu, Hee Chul,Bae, Eun Ju,Park, Byung-Hyun Nature Publishing Group UK 2019 Experimental and molecular medicine Vol.51 No.5

<▼1><P>Adipose tissue inflammation is a reproducible feature of obesity and obesity-linked insulin resistance. Although sirtuin 6 (Sirt6) deficiency has previously been implicated in diet-induced obesity and systemic insulin resistance, the adipocyte-specific role of Sirt6 in the regulation of adipose tissue inflammation and systemic metabolic dysfunction in mice fed normal chow and in humans remains elusive. Here, using <I>Adipoq-Cre</I>-mediated adipocyte-specific Sirt6 knockout (aS6KO) mice, we explored whether adipocyte Sirt6 inhibits adipose tissue inflammation and its underlying mechanism. aS6KO mice fed normal chow gained more body weight and fat mass than wild-type mice and exhibited glucose intolerance and systemic insulin resistance. Measurement of plasma and tissue cytokines and flow cytometric analysis of adipose stromal vascular cells indicated a decrease in alternatively activated M2 macrophages in the adipose tissue of aS6KO mice. Mechanistically, Sirt6 regulated the expression of the canonical type 2 cytokine IL-4 by adipocytes in a cell autonomous manner, which in turn affects M2 macrophage polarization. Consistent with animal experimental data, the degree of obesity and insulin resistance demonstrated by the body mass index, fasting blood glucose and HbA1c correlated negatively with the expression of Sirt6 in human visceral fat tissues. Collectively, these results suggest that adipocyte Sirt6 regulates body weight gain and insulin sensitivity independent of diet, and the increased IL-4 production by Sirt6 and resultant M2 polarization of adipose tissue macrophages may attenuate proinflammatory responses in adipose tissue.</P></▼1><▼2><P><B>Obesity and diabetes: A control protein in fat</B></P><P>A protein in adipose tissue (composed of fat cells) helps protect against inflammation and the development of resistance to insulin that develops in obesity and can lead to type 2 diabetes. Researchers in South Korea, led by Eun Ju Bae at Woosuk University, Wanju, and Byung-Hyun Park at Chonbuk National University, Jeonju, investigated the role of Sirt6 in mice and in human adipose tissue. Deleting the mouse gene that codes for Sirt6 in adipocytes promoted the impaired response to insulin and associated increase in blood glucose levels that are two key aspects of diabetes. Changes in biochemical signaling pathways controlling immune cells called macrophages were implicated in these effects and suggest an anti-inflammatory role for Sirt6. Analysis of human adipose tissue supported these findings. The research will help understand how obesity promotes type 2 diabetes.</P></▼2>

This study was conducted on 367 male workers to evaluate the change of vibration perception threshold(VPT) according to exposure degree to carbon disulfide. VPT was measured on both metacarpal bones of index and little fingers and on fibular malleoli by Vibrometer(Rion, on 125Hz). The exposure degree was classified by the name of department. Workers in department 2 had been exposed to carbon disulfide, those in department 3 had been exposed to undetectable concentration of carbon disulfide. The results were as follows: 1. The mean values of VDT of metacarpal(MC) bones showed dose-response pattern, i.e., the mean values of VPT at department 1 were highest, and those of VPT at department 3 were lowest with similar work duration or age. But the mean values of VPT of fibular malleoli(FM) showed dose-response patter only in workers having above 5 years of work duration or whose age were above 30. 2. The mean values of VPT of MC bone of workers increased by age. 3. There were statistically significant difference in mean values of VPT of MC bone only in workers having 5-10 year work duration. And there were statistically significant difference of mean values of VPT of left 2nd and 5th MC bone in workers whose age was 30's, of right 2nd MC bone in those whose age was 40's, and of left 2nd MC bone in those whose age was 50's. 4. The variables affecting VPT significantly were department and age(or age group) both in multiple regression and general linear model. The department showed to have more effect to VPT than age in multiple regression, but age group showed to have more effect to VPT than department in general linear model. 5. The variables were transformed to indicator variable to do logistic regression analysis. department 1, 2, 3 were classified into high exposure(spinning department) and low duration was classified into long(above 10 years) and short. The exposure and age were significant variables by logistic regression analysis. Odds rations of department and VPT on metacarpal bones or malleoli were 2.7-3.2 and VPT those were 2.6 or 2.7. Odds ratio of age and abnormality of VPT on any point was 3.3(1.59-6.8), and that of department and VPT was 2.8(1.5-5.5). We concluded that exposure of carbon disulfied was significantly associated with reduction of VPT regardless of age; and that the test of VPT would be useful tool for screening and early detection in neuropathy by carbon disulfide or other neurotoxic chemicals, even though it is simple and cheap.

Cadmium(Cd) is an ubiquitous, toxic and nonessential metal which is controversial about the association with a cardiovascular disease. In this study, we investigated the reference level of Cd in myocardium in Korean general population. The level of Cd and zinc(Zn) concentration in myocardium of 252 cases of "sudden and unexpected death" autopsies (male: 172, female : 60) aged 0 to 87 years was analyzed. The concentration of Cd and Zn was determined with atomic absorption spectrophotometer(Perkin-Elmer Model 5100) by flameless and flame method, respectively. The content of Cd and Zn in myocardium showed the log-normal distribution rather than normal distribution. Geometric mean concentration of Cd was 0.19 ㎍/g wet weight in myocardium. The level of Cd in myocardium was not significantly different between male (0.18㎍/g wet weight) and female (0.22㎍/g wet weight). Geometric mean concentration of Zn in myocardium was 25.25 ㎍/g wet weight. The level of Zn between male (25.13 ㎍/g wet weight) and female (25.57㎍/g wet weight) was not different. The deposit of Cd in myocardium was age-dependent of biphasic pattern, but the Zn level by age was not significantly different. The level of Cd in myocardium was increased to the fifties of age, thereafter a leveling-off was shown. The regression model of Cd deposit in myocardium by age was predicted as the following equation: Log Heart-Cd= -1.2726 + 0.0234 ·Age -0.0002 ·Age². The maximum Cd deposit in myocardium was estimated to be 0.26 ㎍/g wet weight at the age of 58.5 in Korean general population. In addition, the total Cd burden in heart by age was predicted as a following equation: Total Cd burden in Heart= -10.165+2.891 ·Age -0.0258 ·Age². The maximum heart burden of Cd was estimated to be 70.7㎍ at age of 55.4. The positive correlation between Cd and Zn was observed in myocardium. The linear regression equation was Log Heart-Zn = 1.4195+0.0262 ·Log Heart-Cd.

Rhabdomyolysis is a syndrome characterized by muscle necrosis and release of intracellular muscle constituents into the circulation. The spectrum of causes is quite broad and included disorders of traumatic, metabolic, infectious and toxic origin. However, rhabdomvolvsis and acute renal failure following bee sting is rare and its pathogenesis is not well known. We experienced a case of 63-year-old man with acute renal failure and rhabdomyolysis caused by bee sting. He was stung by bee on scalp and neck. Oliguria was developed within several hours. He has fully recovered after general supportive care including fluid therapy and diuretics. This case demonstrates that rhabdomvolysis with consequent acute renal failure are able to developed by bee sting.

치아이동 시 피질골 천공이 치조골 재형성에 미치는 영향을 알아보기 위해서 생후 15주된 자성백서를 사용하여 피질골 천공 후 치아이동을 실시한 실험군(Tooth movement with cortical punching: TMC group, n = 16)과 교정적 치아이동만 실시한 대조군(Tooth movement only group: TM group, n = 16)의 치아주위조직을 면역조직화학염색을 통하여 관찰하였다. 실험군과 대조군의 실험동물에 20 gm의 힘으로 상악 전치부 사이를 이개시키는 치아이동을 시행하였으며 실험군에서는 상악 전치부 구개부위에 피질골 천공을 실시하였다. 치아이동 후 1, 4, 7, 14일째에 실험군과 대조군의 실험동물을 희생시켰다. 면역조직화학염색법으로 OPG, RANK, RANKL의 발현을 비교한 결과, OPG의 발현은 양 군 모두에서 미처치 대조군에 비하여 감소되었으나, 실험군에서의 발현이 대조군보다 컸으며, RANK, RANKL은 피질골 천공을 시행한 경우에 더 강한 발현을 보이는 것이 관찰되었다. 따라서 피질골 천공이 치주조직의 OPG, RANK, RANKL의 발현에 영향을 미치며 치조골의 재형성을 향상시키는 것을 알 수 있었다. Objective: The purpose of this study was to investigate whether cortical punching could stimulate the expression of OPG, RANK, and RANKL during tooth movement by immunohistochemistry. Methods: 34 sprague-dawley rats (15 weeks old) were allocated into 3 groups: TMC group (experimental group; Tooth Movement with Corticotomy, n = 16), TM group (control group; Tooth Movement only group, n = 16), and non-treatment group (n = 2). 20 gm of orthodontic force was applied to rat incisors by inserting elastic bands. The duration of force application was 1, 4, 7 and 14 days. A microscrew (diameter 1.2 mm) was used for cortical punching of the palatal side of the upper incisors in the TMC group. Results: Distributions of OPG, RANK, and RANKL were evaluated by immunohistochemistry. OPG, RANK and RANKL were observed on experimental and control groups. On the compression side, the degree of the expression of OPG decreased in both groups. The expression of RANK was most prominent in the experimental group of day 4. The expression of RANKL was most intensive and extensive in the experimental group of day 7. However, the expression of OPG was decreased in the experimental and control groups compared to the non treatment group. The expression of OPG, RANK and RANKL after force application were decreased at day 14. Conclusions: These findings suggested that cortical punching might stimulate remodeling of alveolar bone during a 2 week period of tooth movement without any pathologic change.
