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>

Background : In an era of increasing medical costs, safe reduction in postoperative stay has become a major focus to optimize utilization of healthcare resources. The authors aimed to evaluate the clinical significance of the critical pathway(CP) for gastrectomy patients by implementing standardized postoperative management and electronic medical records. Method : From August 2006 to April 2007, critical pathways were introduced to inpatients and outpatients with gastric cancer. 60 consecutive patients undergoing distal gastrectomy were randomly divided into two groups; 30 CP group(A) and 30 non-CP group(B). Simultaneously, we also retrospectively reviewed the records of 438 patients(C:control group) who were able to be enrolled in CP program. We compared group(A) with (B), (C) in terms of hospital stay, complication rate, use of antibiotics and hospital costs. Patient satisfaction was surveyed by questionnaires. Result : There was no significant demographic difference between group(A) and (B). Of 30 patients in group(A), 5 drop-outs and 14 variances occurred. The mean postoperative hospital stays(Laparoscopy-assisted distal gastrectomy: LADG/Open distal gastrectomy: ODG) were 7.6/10.5 days for the group(A), 8.9/12.7 days for the group(B) and 12.6/14.5 days for the group(C) (p=0.02 in LADG). The total hospital cost of group(A) had a tendency to be less than that of group(B) and the amount of hospital cost per day in group(A) was significantly higher than that in group(B). The usage rates of the first generation antibiotics were 73.33%, 63.33%, and 59.2% in group(A), (B), and (C), respectively. Patients’ satisfaction had a tendency to be higher in the CP group than non-CP group. Conclusion : The mean hospital stay in LADG patients was shortened meaningfully and hospital cost per day was enlarged after introduction of clinical pathway. It is necessary to apply a number of patients to the critical pathway and to make an effort to reduce the variation and drop-out rates.

This study was performed to provide the basic data necessary to prevent child abuse through an investigation of the current status of child abuse and an elucidation of its related affecting variables. Using a questionnaire, data were collected from 655 students, who were the second, fourth, and sixth graders attending at one primary school in Daegu city, and their parents from June 17 to July 19, 2002. The results obtained in this study are summarized as follows: On the recognition of abuse, both the children and their parents had a high recognition level in a severe physical abuse and a sexual abuse, whereas they had a low recognition level in a slight physical abuse, an emotional abuse, and a neglect. The parents had a higher recognition level than the children in a physical abuse. However, the children had a higher recognition level than the parents in an emotional abuse, a sexual abuse, and a neglect. On the frequency of abuse, male students were more experienced than female students (p<0.001), and low graders were more experienced than high graders (p<0.05), younger mother (p<0.01), parents having a high stress (p<0.01), parents having a nuclear family (p<0.05), parents having a low recognition on abuse (p<0.05), parents having a low conjugal affection (<0.05), parents having a bad foresting attitude (p<0.001), parents having more experience of abuse in childhood (p<0.001), and parents having a more experience of worrying about child's matters (p<0.001) had a high frequency of child abuse. A physical abuse had a high positive correlation with an emotional abuse (r=0.604), but had a low positive correlation with a neglect (r=0.285). And there was a moderately high positive correlation between a neglect and an emotional abuse (r=0.515).

Objectives: Posterior cervical microscopic laminoforaminotomy has been a preferred procedure for a posterolateral cervical disc or foraminal stenosis. However, neckpain from wide skin incision and muscle injury are some of disadvantages. The authors performed cervical microscopic laminoforaminotomy with METRx™ tubular dilator system and were compared the results with classical cervical microscopic foraminotomy. Methods: Six patients underwent posterior cervical microscopic laminoforaminotomy using the METRx™ during 6 months. We have selected 10 patients from our institution as a comparison group. Preoperative and postoperative pain score composed of the radicular and neck component was examined and disability score also recorded. Diameters and lengths of laminoforaminotomy on the postoperative CT also were compared with two methods Results: Postoperative pain scores to the radiculopathies were not different but postoperative pain scores to the neckpain on the follow up periods were significantly different. The average vertical and transverse diameters of the laminoforaminotomy defect on the postoperative CT scans were not different between two groups. Average hospital stay of the classical methods was 8.8±7.5 days comparison with 4.5±0.54days of new procedure. Conclusions: Posterior cervical microscopic laminoforaminotomy with METRx™ systems seems to provide similar decompression and clinical results as classical methods compared to classical methods and shows superior results for postoperative neckpain and hospital stays.

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.
