생태복지는 인간의 복지와 건강한 생태계의 상호관계성에 대한 국제적 담론에서 시작되었다. 본 연구는 국립공원이 생태복지의 최대 실현가능 지역이라는 점에서 국립공원에 적합한 ‘국립공원 생태복지’ 개념을 정립하고 정책방향을 설정함으로써 향후 국립공원에서의 생태복지 실현을 도모하기 위한 기초자료를 제공하는데 그 목적이 있다. 이를 위해 사전워크숍과 총 2회에 걸친 델파이 조사를 수행하였다. 본 연구를 통해 ‘국립공원 생태복지’는 국립공원에서 생태계의 지속가능성과 생물다양성을 유지하며, ‘국립공원 인간복지’와 ‘국립공원 생태계복지’의 조화를 지향하는 복지로 정의되었다. 2차 델파이 결과 모든 항목에서 평균 4.00 이상, 내용 타당도(CVR) 0.37 이상, 변이계수(CV)0.5 미만으로 타당한 내용으로 확인되었다. 국립공원 생태복지의 정책방향을 설정하기 위해 생태복지의 바탕이 되는 생태계서비스의 요소들 중 국립공원에 적합한 주요 요소를 도출한 결과 공급서비스에서 먹이·식량, 물, 유전자원 3항목, 조절서비스와 기반(서식지)서비스의 모든 항목, 문화서비스에서 미적정보, 휴양관광, 심신치유, 지식체계ㆍ교육적가치 4항목이 최종 도출되었다. 또한 본 연구에서는 국립공원 생태복지의 개념과 향후 국립공원 생태복지 정책이 어떻게 나아가야할지 방향성을 제시하였다. 그러나 이를 실현하기 위해서는 향후 이에 대한 구체적인 단위사업에 대한 실행계획이 수반되어야 하며 이를 위한 추가적인 연구가 필요할 것이다. The concept of Eco-welfare emerged in the process of discovering the relationship between a healthy ecosystem and human wellbeing. The objective of this study is to offer basic data for eco-welfare policy realization by conceptualizing the ‘National Park Eco-welfare’ since national parks are appropriate places for eco-welfare to be optimally implemented. A pre-workshop and two rounds of Delphi surveys were conducted to determine the concept of the ‘National Park Eco-welfare ’ and the main elements to be included in ecosystem service. Through this study, the concept of ‘National Park Eco-welfare’ was defined as efforts to conserve the biodiversity and sustainability of the ecosystem and create harmony between ‘National Park Ecosystem Welfare’ and ‘National Park Human Welfare’. To establish the direction of the National Park Eco-welfare policy, we identified the main elements of ecosystem services which are appropriate for the National Park. These are comprised of 3 elements (food, fresh water and genetic resources) from supply service, all elements from regulating service and supporting/habitat service and 4 elements (aesthetic information, recreation-based ecotourism, healing, and knowledge systems with educational values) from culture service. In this study, the concept of National Park Eco-welfare was established, and its policy objectives and scope were suggested. However, further studies are necessary to develop action plans areand thereby realize the policy.

Background GBA1 mutations are the most common genetic risk factor for development of Parkinson’s disease (PD). The loss of catalytic activity in GBA1, as well as the reduction of the GBA1 protein in certain cellular compartment, may increase disease progression. However, the mechanisms underlying cellular dysfunction caused by GBA1 deficiency are still mostly unknown. Objective In this study, we focus on the genetic interaction between GBA1 deficiency and PD-causing genes, such as DJ-1, in mitochondrial dysfunction. Methods GBA1 knockout (KO) SH-SY5Y cells were used to assess DJ-1 functions against oxidative stress in vitro. The levels of cellular reactive oxygen species were monitored with MitoSOX reagent. The expression of the PARK7 gene was analyzed using the quantitative real-time PCR (qRT-PCR). To understand the mechanism underlying DJ-1 upregulation in GBA1 KO cells, we assess ROS levels, antioxidant protein, and cell viability in GBA1 KO cells with treatment of ROS inhibitor N-acetyl-cysteine or miglustat, which is an inhibitor of glucosylceramide synthase. Dopaminergic degeneration was assessed from Gba1 L444P heterozygous mice mated with Park7 knockout mice. Results We find that DJ-1 is significantly upregulated in GBA1 KO cells. Elevated levels of DJ-1 are attributed to the transcriptional expression of PARK7 mRNA, but not the inhibition of DJ-1 protein degradation. Because DJ-1 expression is highly linked to oxidative stress, we observe cellular reactive oxygen species (ROS) in GBA1 KO cells. Moreover, several antioxidant gene expressions and protein levels are increased in GBA1 KO cells. To this end, GBA1 KO cells are more susceptible to H2O2-induced cell death. Importantly, there is a significant reduction in dopaminergic neurons in the midbrain from Gba1 L444P heterozygous mice mated with Park7 knockout mice, followed by mild motor dysfunction. Conclusion Taken together, our results suggest that DJ-1 upregulation due to GBA1 deficiency has a protective role against oxidative stress. It may be supposed that mutations or malfunctions in the DJ-1 protein may have disadvantages in the survival of dopaminergic neurons in the brains of patients harboring GBA1 mutations.

The purpose of this study is to categorize the store attributes as a valuation basis and to suggest the order of priority by Importance-Performance Analysis when new or improving plan about Urban Entertainment Center(UEC) is under consideration. The literature was reviewed based on the previous studies and survey was conducted. The questionnaire was conducted for users of four UECs in Seoul and 126 copies were analyzed by SPSS windows. The results were summarized as follows: First, 'transportation connection', 'tenant composition', 'wayfinding to destination', 'air quality', and 'public transportation' which have high mean of importance will be considered first when new UEC will be planned from now on. Second, the order of priority for the improvement plan was deducted by Importance-Performance Analysis. It is the most necessary to effort for the improvement of the 'location of dining facility', 'entrance discernment', 'change of direction at node', 'wayfinding to destination', 'vertical shifter', 'indoors air quality', and 'price'. The continuing status quo is required for 'tenant composition', 'tenant arrangement', 'various retail facility', 'various entertainment facility', 'location of entertainment facility', 'transportation connection', 'surrounding facilities connection', 'passageway width', 'rest place', 'indoor temperature', 'convenient parking', 'public transportation', 'security', 'safe against accident', 'quality', 'promotion', and 'personal service'. On the other hands, 'landmark', 'visual openness', 'interior design', 'delight ambience', 'retail kiosk', dining kiosk', 'play implement', 'play experience', 'performances experience', 'event experience', and 'approach distance' are low priority on the effort to improve the customer demand.

The rs196952262 Polymorphism of the AGPAT5 Gene is Associated with Meat Quality in Berkshire Pigs

Woo Bum Park,Sang Mi An,Go Eun Yu,Seulgi Kwon,Jung Hye Hwang,Da Hye Park,Deok Gyeong Kang,Tae Wan Kim. Hwa Chun Park1. Jeongim Ha*.,Chul Wook Kim* 한국축산식품학회 2017 한국축산식품학회지 Vol.37 No.6

High-quality meat is of great economic importance to the pig industry. The 1-acylglycerol-3- phosphate-O-acyltransferase 5 (AGPAT5) enzyme converts lysophosphatidic acid to phosphatidic acid in the mitochondrial membrane. In this study, we found that the porcine AGPAT5 gene was highly expressed in muscle tissue, influencing meat characteristics, and we also identified a non-synonymous single-nucleotide polymorphism (nsSNP) (rs196952262, c.673 A>G) in the gene, associated with a change of isoleucine 225 to valine. The presence of this nsSNP was significantly associated with meat color (lightness), lower cooking loss, and lower carcass temperatures 1, 4, and 12 h after slaughter (items T1, T4, and T12 on the recognized quality scale, respectively), and tended to increase backfat thickness and the waterholding capacity. These results suggest that nsSNP (c.673A>G) of the AGPAT5 gene is a potential genetic marker of high meat quality in pigs.

Interaction between Brain-Derived Neurotrophic Factor Val66Met Polymorphism and Recent Negative Stressor in Harm Avoidance

Kim, Seog Ju,Cho, Seong-Jin,Jang, Ha Min,Shin, Jonghan,Park, Pil-Whan,Lee, Yu Jin,Cho, In Hee,Choi, Jung-Eun,Lee, Heon-Jeong S. Karger AG 2009 Neuropsychobiology Vol.61 No.1

<P>There have been controversial results regarding the association between brain-derived neurotrophic factor (BDNF) Val66Met polymorphism and anxiety-related traits such as harm avoidance (HA). We aimed to investigate the interaction between <I>BDNF</I> Val66Met polymorphism and negative life stressors in HA. <I>BDNF</I> Val66Met polymorphism was genotyped in 391 community-dwelling Koreans (152 males, 239 females; 43.2 ± 14.1 years old). The Temperament and Character Inventory (TCI) and the Center for Epidemiological Studies for Depression Scale (CES-D) were self applied. The Structured Clinical Interview for DSM-IV axis I disorders and face-to-face interviews investigating negative life stressors within the last 6 months were also performed. There was no significant difference in TCI score, major depressive disorder prevalence and CES-D score among the 3 genotypes (94 Met/Met, 188 Val/Met and 109 Val/Val subjects). There was no significant difference in TCI scores between subjects with stressors and those without stressors, while more common major depressive episodes (p = 0.03) and higher CES-D scores (p < 0.001) were found in subjects with stressors. However, there was a significant interaction between the <I>BDNF</I> genotype and negative life stressors in HA (p = 0.02). Only subjects with the Val/Val genotype showed higher HA with recent negative stressors. Our finding suggests that <I>BDNF</I> Val66Met polymorphism might influence HA by interacting with recent negative stress experience.</P><P>Copyright © 2009 S. Karger AG, Basel</P>

하배진,남천석,박은경,강금석 신라대학교 자연과학연구소 2006 自然科學論文集 Vol.15 No.-

In the present study the hepatoprotective and antioxidative effects of Epimedium koreanum (EK) and Salicornia herbacea (SH) were investigated against carbon tetrachloride (CCl_(4))-induced liver damage in rats. EK and SH (100 mg/kg) were administered into rats intraperitoneally (i.p) for 2 weeks. After CCl_(4) a dose of 3.3ml/kg was administered to induce hepatotoxicity. This antioxidative effects of EK and SH on CCl_(4) -treated rats were measured through the activity of Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) in serum and Superoxide dismutase (SOD), Catalase (CAT) in liver tissue. EK or SH-administered and CCl_(4) -treated (ECT or SCT) groups showed inhibitory effects in AST and ALT activities compared to CCl_(4) -treated control (CTC) group. SOD and CAT in ECT and SCT groups were increased compared to those of CTC group.

박은하,도연실,양정채,강미라,서현주,정숙인,손준성,기현균,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

박광하,권영두,정영진,장은경 한국공업화학회 2004 공업화학 Vol.15 No.1

본 연구에서는 동해안 해조류인 구멍갈파래를 아크릴아미드에 고정하여, Cd(Ⅱ) 및 Pb(Ⅱ) 중금속 이온의 흡착 특성을 살펴보았다. 수순한 Ulva pertusa 및 Si-Ulva pertusa 흡착제보다는 아크릴아미드에 고정화된 Ulva pertusa의 경우 많은 양의 중금속이 흡착되었으며, Pb(Ⅱ) 이온이 Cu(Ⅱ) 이온보다 더 잘 흡착되는 것으로 나타났다. 흡착제의 농도가 작은 경우 중금속 이온의 흡착량은 pH에 큰 영향이 없었으나, 흡착제의 농도가 클 경우 중금속 이온의 흡착량은 pH에 큰 영향을 받았다. pH에 따른 중금속 이온의 흡착량은 pH 10.5 > 8.5 > 7.0 > 5.5 > 3.5 순으로 나타났다. 아크릴아미드에 고정화된 Ulva pertusa의 단위 질량에 대해 Cd(Ⅱ) 및 Pb(Ⅱ) 이온의 최대 흡착량은 각각 최대 8.73 ㎎과 13.20 ㎎으로 나타났다. 또한 Cd(Ⅱ) 및 Pb(Ⅱ) 이온의 회수율은 pH에 따라 다소 차이가 있었으나, 각각 61.3~75.5% 및 61.4~54.1%로 나타났다. 중금속 이온의 회수에 있어서 산성 조건이 알칼리성 조건보다 효율적이었으며, 본 실험에 의한 중금속 이온의 흡착 특성은 Freundlich 흡착 특성과 잘 일치하는 것으로 나타났다. Adsoprtion characteristics of Cd(II) and Pb(II: heavy metal ions onto the Acrylamide-immobilized Ulva pertusa, and algae of the eastern coastal area. was examined in this work. Much amounts of heavy metal ions were adsorbed onto the Acrylamide-immobilized than either bare Ulva pertusa or Si-Ulva pertusa. It was also observed that Pb(II) was more readily adsorbed on the algae that Cu(II). The adsorption amounts of heavy metal ions showed no great dependence on the pH value at low adsorbent concentration, but those were high dependent on pH value at high adsorbent concentration. The adsorption amounts of heavy metal ions were in the following order; pH 10.5 > 8.5 > 7.0 > 5.5 > 3.5. The maximum adsorption amounts of Cd(II) and PB(II) onto Ig of Acrylamide-immobilized Ulva pertusa were 8.73 mg and 13.20 mg, respectively. It was found that recovery yields of Cd(II) and Pb(II) ions were in the range of 61.3∼75.5% and 61.4∼54.1% depending on the pH level. In the heavy metal recovery, acidic condition was more efficient that alkaline condition. The adsorption behavior of these heavy metal ions was well matched with the Freundlich adsorption isotherm.
