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.

This study was conducted at a Terminal, a Parking Lot, an Underground shopping center, a Funeral hall and a Hospital waiting room of Cheon An area in August 2008 to examine the concentration level of HCHO(formaldehyde). The concentration level of the remodeled sites were 39.4 ± 12.0 ㎍/㎥ in the terminal, 32.7 ± 7.3 ㎍/㎥ in the parking, and 97.8 ± 29.4 ㎍/㎥ in the underground shopping center. The underground shopping center had the highest level and followed by the terminal and the parking. On the contrary, the site remodeling had the level of 17.7 ± 12.4 ㎍/㎥ in the funeral hall and 17.9 ± 0.6 ㎍/㎥ in the hospital waiting room. The funeral hall had highest level than that of the hospital waiting room. Both the remodeled sites and the not remodeled site had concentration level of HCHO below the standard level, but it was higher in the remodeled sites. There were no relations among the HCHO, the temperature and the humidity in facilities of Cheon An area.

Wernicke encephalopathy is an acute neurologic disorder attributable to thiamine (vitamin B1) deficiency. We report the case of a 61-year-old female patient who presented Wernicke encephalopathy after surgery for pancreatic head cancer. From the ninth postoperative day, she had suffered from nausea and vomiting and had difficulties ingesting food, she was given total parenteral nutrition (TPN), but lacked adequate vitamin (thiamine) supplementation. After 28 days, she developed ataxia, ophthalmoplegia, and mental confusion. The magnetic resonance image showed pathologic changes in the medial thalamus,periaqueductal gray matter, medulla and mamillary bodies. The blood level of thiamine was very low. After intravenous and oral supplementation of thiamine (200 mg/day), consciousness was soon normalized and neurologic symptoms have gradually been improving. Nausea and vomiting disappeared after administration of a low dose of mirtazapine (7.5 mg/day). We emphasize the importance of thiamine supplementation to the patients who suffer from vomiting which hinders them from taking food and who require prolonged TPN.

A symbiotic bacteria associated with Galleria mellonella larva was isolated and identified as Xanthomonas maltophilia sp. by using the BioLog Automated Microbial Identification System. Also three other strains of bacteria were isolated from Galleria mellonella larvae and identified as CDC group DF-3, Enterobacter agglomerans biogroup 5, and Serratia marcescens sp., respectively. Several biochemical and physiological tests were performed to determine the strain characters. X. maltophilia did not adsorb neutral red of bromothymol blue and grew below 37℃. Xanthomonas maltophilia and three other strains were pathogenic against the insect host when they were injected into hemolymph of the insect. X. maltophilia was rod-shaped and its cell size was ranged from 1㎛ to 2㎛.

Farm price and income instability will reemerge as a major problem of agriculture in the post Uruguay Round period. The Korean government attempts to introduce the various types of direct payment allowed by WTO, and the farm income stabilization program is one of those. The objective of this study is to examine necessities for and devices of farm income stabilization program. The major findings of the study are summarized as follows: 1. Considering Agreement on Agriculture of UR, foreign examples and characteristics of korean agriculture, it is desirable to introduce a whole-farm income stabilization program like Canadian NISA(Net Income Stabilization Account) rather than programs by commodity. 2. The farm income stabilization program recommended in this study is a voluntary program that helps producers save money in good times to stabilize their incomes when farm revenues drop. In the program, producers deposit funds(1.5% of gross receipts) into their own account and receive a matching contribution(3% of gross receipts) from the government. 3. By introducing this program, stabilization and support of the farm income, increase of food production and maintenance of regional society are expected. Opinion survey showed that 80 percent of regional experts were in favor of this program. 4. The problems to be solved in the process of the program include conflicts with other programs, low participation rate of farmers, moral hazard in investigating eligible gross receipts, and administrative and technical difficulties.

This paper is a method to maintain the right of possesion for color images. previous method used an binary data, image, or binary pattern etc. So watermarked image was declined in image quality. But the information for insertion was limited. This paper proposed the method which will change RGB mode of original image to YIQ, at first, we will insert the watermark in the Low frequency cofficient of wavelet transform domain. The watermark use the owner's photo of a digital contents. which is 256 gray-level watermark, and it's size can be changed by the size of original image. As the result of simulation, our method can provide the rightful1 ownership against Rotation, Cropping, JPEG, and Scaling attacks.

활동이론의 관점에서 바라본 박물관, 커뮤니케이션, 그리고 학습

박지연,이수민,이병준 한국문화교육학회 2011 문화예술교육연구 Vol.6 No.4

Museum is a medium which communicates with previous generation's experiential memories and present generation's cultural memories. Therefore, the communication is a core task in museum. Museum needs mediums like exhibition and education and we have to discuss how to structuralize these things. The museum communication could be explained through the Cultural-Historical Activity Theory(CHAT). The CHAT has been developed by several theorists like Vygotsky. Especially, the third generation's CHAT has been developing by Engeström. It is a worthy theoretical structure that can show museum as a messenger of communication in society and its communication problems. This study is based on the CHAT and analyzes museum in a social activity system and activity system in a museum from micro/macro-scopic view. Also, it produces practical models that connect museum with community art field and museum with schools. 박물관은 앞선 세대의 체험적 기억을 현 세대에게 문화적 기억의 형태로 커뮤니케이션하는 매개체이다. 따라서 박물관에서 소통(communication)이라는 개념은 핵심적인 과제일수 밖에 없다. 박물관은 그 자체로 전시와 교육과 같은 매체(medium)를 필요로 하며 이를 어떻게 구조화할 것인가의 문제가 박물관커뮤니케이션의 측면에서 논의될 필요가 있다. 이러한 거시적, 미시적 차원의 박물관커뮤니케이션의 과제는 비고츠키와 여러 이론가들의 연구성과를 정리하고 발전시킨 활동이론에 의해 잘 설명될 수 있을 것으로 보인다. 특히 Y. Engeström에 의해 발전된 제3세대 활동이론은 사회속에서의 커뮤니케이션의 전달자로서의 박물관과 박물관내에서의 커뮤니케이션의 문제를 잘 드러낼 수 있는 이론체계라고 생각된다. 본 연구는 활동이론에 근거하여 거시적·미시적 관점에서 사회활동시스템 속에서의 박물관과 박물관 내에서의 활동시스템을 분석하고 이를 통해 박물관의 커뮤니케이션을 박물관 내부 활동시스템 간의 네트워크 실천, 박물관과 지역의 예술장(藝術場)이 연계된 네트워크 실천과 박물관과 학교가 연계된 네트워크 실천 모형을 구조화하여 제시하려 한다.

β-lactamase를 생성하는 Xanthomonas maltophilia의 배지조정과 배양조건의 최적화

박선호,유연수 啓明大學校 産業技術硏究所 1998 産業技術硏究所 論文報告集 Vol.21 No.1

Xanthomonas maltophilia, which can produce β-lactamase, were isolated from Galleria mellonella larvae. Medium composition for bacteria growth was optimized. As a result, the best nitrogen source was found to be yeast extract. The medium composition consisted of 5% yeast extract, 0.5% NaCl, and 0.5% KH₂PO₄. The optimum temperature for cell growth was 28℃. The culture pH approached to about 9.0 during the cell growth period regardless of initial pH ranging from 6 to 10. Meanwhile, the carbon sources such as glucose or fructose showed as decreasing trend of pH and thus inhibited the further cell growth. The specific growth rate of X. maltophilia in a 5L-fermentor was 2.6 times greater than that in a flask culture, presumably due to enhanced aeration and agitation conditions.
