It is generally recognized that monitering of bio-molecules, which are related to the ocean environment, becomes more important. So far, for the detection of the bio-molecules, ocean samples were brought to laboratory to be analyzed using a complicate and expensive measuring system The "ship and dip" method takes a relatively long time to complete a analysis cycle and causes significant errors due to the time difference between the analysis processes. In order to overcome the drawbacks, developments of sensors for the detection of bio-molecules were suggested using nano-technology, such as nano-spintronic device, carbon nano tube device, and nano-semiconductors. The pros and cons of the technology were examined and reinvestigated to overcome the technical problems in the application to real sensors.

저성장 어린이들을 대상으로 하는 성장호르몬 치료는 다양한 부작용과 투여과정의 스트레스로 인한 환자 순응도 감소, 고가의 치료 비용 등의 단점을 가지고 있다. 이러한 이유로 부작용 발생의 위험성이 작고 낮은 비용으로 어린이의 성장에 도움을 줄 수 있는 천연물 유래 기능성 소재 개발에 대한 관심이 증가하고 있다. 그러나 성적으로 미성숙 상태인 어린이를 대상으로 한다는 점, 에스트로겐에 의한 뼈 성장과 성조숙증 발병기전 연관성, 천연물에 존재하는 다양한 식물성 에스트로겐의 영향으로 안전성에 대한 우려가 존재하는 것이 사실이다. 따라서 본 연구에서는 앞선 연구를 통하여 뼈 성장 촉진 효과가 확인된 시험물질의 안전성을 확인하기 위하여 난소를 절제한 실험동물에 시험물질을 4주간 투여한 후 시험물질이 식물성 에스트로겐으로 작용하여 성조숙증과 성장호르몬 이상을 일으킬 가능성을 확인하고자 하였다. 실험 결과 난소 절제로 인한 체중증가, 혈중 지질 농도의 증가, 자궁 벽 두께의 감소 등이 나타남을 확인하였으며 시험물질의 4주 투여가 이러한 변화에 영향을 끼치지 않음을 확인할 수 있었다. 또한 혈중 에스트로겐 농도, 혈중 성장호르몬 농도를 분석한 결과 시험물질 투여가 아무런 영향을 주지 않음을 확인하였다. 이러한 결과는 백수오와 한속단 동량 혼합물이 생체 내에서 식물성 에스트로겐으로 작용하지 않는다는 것을 의미하며 반복투여에 의한 성장호르몬 이상을 일으키지 않는 것으로 판단된다. Cynanchum wilfordii and Phlomis umbrosa Turcz. are known to contain isoflavone, a representative phytoestrogen. This study was performed to determine whether the extract mixture of C. wilfordii and P. umbrosa Turcz. would induce an estrogenic effect in ovariectomized rats. The extracts were administered to the ovariectomized rats at 30, 60, 120 mg/kg per day for 4 weeks, respectively. They showed no estrogenic effect, which was indicated by the decrease in uterus wall thickness as well as the increase in body weight and the level of cholesterol and triglyceride. The extracts also had no effect on the concentrations of estrogen and growth hormone in the serum. However, the increase in alkaline phosphatase activity, which leads to protection against the bone loss caused by ovariectomy, was noted on administration of the extract. Therefore, it seemed that the extracts of C. wilfordii and P. umbrosa Turcz. had no estrogenic effect in rats.

한송희(Han, Song-Hee),장인성(Chang, In-Soung),채기웅(Chae, Ki-Woong),정선용(Chung, Son-Young),이철구(Lee, Chul-Ku) 한국산학기술학회 2011 한국산학기술학회논문지 Vol.12 No.6
본 연구에서는 소규모 수도시설에서 수질기준을 자주 초과하는 항목으로 지적되고 있는 불소와 질산성질소 를 효과적으로 제거하기 위하여, 탄소나노튜브를 이용한 전극을 제작하여 전기흡착 공정에 적용함으로써 두 종류의 무기이온 제거 가능성을 평가하였다. 탄소나노튜브를 활용한 전극을 제작하기 위해 코팅 (coating)법과 소결(sintering) 법을 이용하여 전극을 제작하였다. 코팅전극은 바인더의 종류, 소결전극은 소결온도를 변화시켜 각각의 전극을 제작 하였다. 제작된 전극을 이용하여 전류밀도 및 반응시간 등을 변화시켜가며 전기흡착 실험을 진행한 결과 유기바인더 를 이용해 제작된 전극의 이온제거율은 불소 46%, 질산성질소 99.9%로 무기바인더를 이용하여 제작된 전극보다 제거 효율이 우수하였다. 또한 소결하여 제작된 탄소나노튜브 중 1000℃ 고온에서 제작한 전극은 불소 77%, 질산성질소 87%의 제거율을 보여 850℃ 저온에서 제작한 전극보다 더 높은 제거효율을 보임을 확인하였다. 적당한 전류밀도 및 반응시간 하에서 모두 먹는 물 수질 기준에 적합한 농도로 처리될 수 있음을 보임으로써, 탄소나노튜브를 활용하여 제작한 전극을 채택한 전기흡착 공정이 소규모 수도시설에 적합한 공정으로 평가받을 수 있을 것으로 판단된다. Water qualities in the decentralized water treatment plants do not frequently satisfy the water standard limit, in particular, fluoride and nitrate are notorious for the poor removal. In this study, an electro-adsorption equipped with carbon nonotube (CNT) electrodes were carried out to effectively remove the nitrate and fluoride in the decentralized water treatment plants. Two types of CNT electrodes, coating and sintering electrodes were applied. Coating electrodes were made based on different kinds of binder and sintering electrodes were made based on different sintering temperature. Removal of fluoride and nitrate when the coated electrodes with organic binder were used for electro-adsorption were 46 and 99.9% respectively, which were better performances than the coated electrodes with inorganic binder were used. On the other hand, removal of fluoride and nitrate when the electrodes sintered at higher temperature (1,000℃) were 77 and 87% respectively, which were better performances than the electrodes sintered at lower temperature (850℃). As a consequences, the electro-adsorption equipped with a CNT electrodes could be an potential alternative process for the removal of fluoride and nitrate in a decentralized water treatment plants if proper current density and contact time were applied.

Rural tourism village experience is proceeded quantitatively without distinct characteristic. This research aimed at analyzing the experience and utilizing in the establishment of differentiation and contents development. Type of experience activity was classified as 10 types in Level 1 and 0~4 types in Level 2. As the result of analyzing 3,007 experiences in 168 villages, types of experience activity implemented per 1 village was 17.9. Among them, ecological experience type appeared to be the most, and appeared in order of food, agriculture farming experience. In respect of agriculture farming experience, ‘harvest and utilization’ was analyzed to be the highest, and regarding rural farmhouse living experience displayed ‘farmhouse living’experience the highest. Tradition courtesy experience displayed‘traditional culture’ experience the highest, and rural food experience was analyzed to implement ‘food making’ experience the most. Ecological experience mainly consisted of ‘hunting and collecting’ and ‘observation/learning’, in case of play experience,‘traditional play’experience activity was analyzed to be performed the most. Considering utilization material, it appeared in order of ‘rice’, ‘sweet potato’,‘potato’, ‘corn’, ‘chili’, ‘agricultural implement’, ‘farmhouse’, ‘animal’, ‘culture’, ‘history’, ‘rice cake’, ‘alcoholic drink’, ‘tofu’, ‘kimchi’, etc. The place of ecological experience was performed in the forest the most, and lots of experience was performed in stream, valley, and river. The researcher expects that characteristic experience activity will be developed based on this result, by avoiding doubleness of the experience activity among the regions and the villages.

한국 재난영화의 정치적 무의식 : 2010년대를 중심으로
한송희(Songhee Han) 사단법인 언론과 사회 2019 언론과 사회 Vol.27 No.2
이 연구는 2010년대 한국 재난영화의 등장 및 흥행을 하나의 문화현상으로 간주하고 사회와의 긴밀한 연관 속에서 분석한 글이다. 최근에 일었던 한국 재난영화의 강세는 ‘글로벌 위험사회’가 핵심 키워드가 된 보편의 역사와 재난영화를 더 이상 오락적 대상으로 소비할 수 없는 한국의 특수한 맥락이 교차하는 지점에서 생겨난 문화현상이다. 또한 동시에 이들 영화는 스펙터클 이미지를 전면에 배치하고 할리우드 전통의 재난 관습을 따르면서도, 한국 사회라는 구체적인 현실을 압축적으로 표상해 지정학적 특수성을 깊이 새기고 있는 징후적 텍스트다. 따라서 재난 서사의 흥행이라는 문화현상을 총체적으로 이해하기 위해서는 한국 재난영화를 동시대 한국 사회라는 역사적 지평 속에 위치시키고 그 재현체계를 맥락적으로 재구성할 필요가 있다. 이러한 인식을 바탕으로 이 연구는 2010년대에 개봉한 일곱 편의 한국 재난영화-<연가시>(2012), <타워>(2012), <더 테러 라이브>(2013), <감기>(2013), <부산행>(2016), <터널>(2016), <판도라>(2016) 등-를 알레고리적으로 독해하고 이들 영화의 정치적 무의식을 탐구한다. 한국 재난영화는 여러 종류의 유토피아적 충동을 드러냄으로써 다양한 논의를 이끌 수 있는 정치적 무의식을 지닌다. 그러나 이런 소원 충족적 판타지는 텍스트의 억압에 의해 표면에 드러나지 못한 채 단지 무의식의 형태로서만 존재할 뿐이며 이를 비판의식으로 변환시키기 위해서는 텍스트에 개입해 적극적으로 해석할 관객의 존재가 선행되어야 한다. 이 연구는 최종적으로 한국 재난영화가 시대적·사회적 상흔을 새기고 있는 문화 텍스트로 간주되어 다층적인 해석이 활발히 이루어질 때 새로운 논의가 시작될 수 있음을 주장한다. This study considered the appearance and success of Korean Disaster Films in the 2010s as a cultural phenomenon and analyzed them in close relation to society. The popularity of Korean Disaster Films in the 2010s is a cultural phenomenon arising from the intersection of the global context in which the ‘Global Risk Society’ has become a keyword in terms of Liquid Modernity and late capitalism, and of the specific local condition that can no longer consume disaster movies as entertainment. Also these films are a symptomatic text that place the spectacle images at the front and follows the style of Hollywood’s Disaster films, and are engraved with the geopolitical specificity by presenting a reality of Korean society compressively at the same time. To fully understand the cultural phenomenon of the disaster themes’ hit, we need to take places Korean Disaster Films in the historical horizon of recent Korean society and reconstructs the representation systems contextually. Based on this perception, this study analyzes seven disaster films released in the 2010sᐨDeranged(2012), Tower(2012), The Terror Live(2013), The Flu(2013), Train to Busan(2016), Tunnel(2016), Pandora(2016)ᐨallegorically and then explores ‘the Political Unconscious’ of these films. Korean Disaster Films have ‘the Political Unconscious’ that can lead to various discussions by revealing different kinds of utopian impulses. However, such wishᐨfulfilling fantasies exist only as a form of unconscious without being exposed to the surface by the suppression of the text. Therefore to transform it into criticism by drawing it out to the surface, the presence of the audience to intervene in the text and interpret it actively should be preceded. This study ultimately suggest that new discussion can be initiated only when Korean disaster films are regarded as a cultural text that engraved with historical and social scars and a multiᐨlayered interpretation is active.
