최근 환경오염으로 인한 날씨의 변화, 자원 고갈에 따른 국제 유가의 상승 등 날씨 및 에너지 문제가 기업이나 국가 심지어 개인의 일상생활, 경제활동에 크나큰 영향을 미치고 있다. 이와 같은 이유로 대체에니지 중 태양 에너지 개발에 필요한 일사량 관리와 기후 데이터의 변화 특성 등을 근거로 지역성 규명에 관한 연구가 많이 이루어지고 있다. 그리나, 아직까지는 데이터 마이닝을 통한 지역적 특성에 따른 군집 및 체계적인 분석 데이터 검색 서비스가 효과적으로 제공되지 않고 있다. 이 논문에서는 국내에서 측정된 기후데이터를 저장 및 관리하기 위한 데이터를 모델링하고, κ-means 기법을 이용하여 국내 기후 데이터를 지역적 특성에 따라 군집함으로써 체계적인 데이터 정보를 제공한다. 그리고 이 정보를 날씨 마케팅에 적용될 수 있는 방법을 제시한다. 제안 시스템은 기업의 날씨 마케팅 연구 및 이에 영항을 미치는 요소와 분석 정보를 제공할 수 있는 기본 데이터베이스 구축에 유용하게 활용될 것이다. Recently, the weather is influenced by the environmental pollution and the oil price is rising because of the lack of resources. So, the weather and energy are influencing not only enterprise or nation, but also individual daily life and economic activity very much. Because of these reasons, there are so many researches about management of solar radiation needed to develope solar energy as alternative energy. And many researchers are also interested in identifying the area according to changing characteristics of climate data. However, so far, the researches have not been developed how to apply the cluster analysis, retrieval and analytical results according to the characteristics of the area through data mining. In this paper, we modeled the data for storing and managing the climate data tested in twenty cities in the domestic area. And we provided the information according to the characteristics of the area after clustering the domestic climate data, using κ-means clustering algorithm. And we suggest the way how to apply to the department store and amusement park as an applied weather marketing. The proposed system is useful for constructing the database about the weather marketing and for providing the elements and analysis information, influencing to the weather change.

In many cases, acute cerebrovascular disease is accompanied by abnormal electocardiograms. Also, though rather uncommon, acute myocardial infraction is also seen. The mechanism of its occurance is uncertain but it is thought to be related to coronary artery spasms, an abnormal autonomic nervous system, and a catecholamine increase. A female patient of 34 years of age came to the hospital because of sudden headache accompanied by substernal chest pain. A subarachnoid hemorrhage due to a cerebral aneurysm rupture had occured, and there was ST segment elevation in lead II, III, and aVF of the electrocardiogram. A cardiac enzyme test, an echocardiography, and a coronary angiography were performed, and she was diagnosed to have acute myocardial infarction due to coronary artery spasm. Clipping of the aneurysm was performed. With the use of nitrate and an angiotension converting enzyme inhibitor, the condition of the patient improved.

It is prerequisite of orthodontists to diagnose malocclusion correctly and make treatment plans accurately for treating maloccluded patients efficiently and earning more stable and better results. Recently computers were introduced in orthodontic diagnosis steps, which enabled orthodontists to get more precise diagnosis, to make more accurate treatment planning and to provide better orthodontic cares for more patients. The authors studied on the diagnostic analysis methods which have been used frequently in Korea and made a diagnostic computer program including the horizontal and/or vertical measurement of length, degrees and proportions in lateral cephalometric radiographs, the analysis of the skeletal and soft-tissue features and the evaluation of the treatment results. We also made a scheduling program for arrangement and management of patients. 40 skeletal and 24 soft-tissue landmarks were selected in a lateral cephalometric radiographs. The available analysis methods in this program are Angular analysis, Linear analysis, Ricketts analysis, Profilogram, Steiner analysis, Tweed analysis, MacNamara analysis, Open bite analysis, Kim's diagnosis, Skeleto-dental cephalometric analysis and Height& weight analysis. We suggested that this diagnostic computer program make it possible for orthodontists to get more rapid and accurate diagnostic analysis and treatment planning and for patient to earn better and more efficient orthodontic service.

This research studied the characteristics and applicability of electrocoagulation using aluminium electrode for the color and COD removal in textile wastewater. Electrocoagulation reactor used two different electrode, Fe and Al, since in the general chemical wastewater treatment, aluminium and ferrous salts were used as coagulants. Aluminium electrode showed higher removal efficiency of color and COD than ferrous electrode did. The COD and color removal efficiency improved at the 0.192A/dm^2 current density. Thus, the electrocoagulation process with bipolar aluminium electrode showed better efficiency in the decolorization and COD removal rate of textile wastewater effluent than custom coagulants did.

Sperm-mediated gene transfer (SMGT) can be used to transfer exogenous DNA into the oocyte at fertilization. The main objective of this study was to assess efficiency of transferring mitochondrial DNA (mtDNA) fragment into boar spermatozoa in either presence or absence of liposome and quality of transfected spermatozoa. The mtDNA of chicken liver was isolated and purified by phenol and alkaline lysis extraction, and it was inserted to plasmid. The genome of transfected spermatozoa treated with DNase Ⅰ was purified by alkaline lysis, and then amplified by the PCR analysis. After electrophoresis, DNA quantitation of each well was calculated by comparison of the band intensity with standard. As a result, exogenous DNA was composed of mtDNA fragment (1.2 kb) and plasmid (2.7 kb). On the other hand, efficiency of transfection by liposome (9.0±0.34 ng/l) in SMGT was higher than that by DNA solution (6.9±0.53 ng/l). However, there was no significant difference. Transfering exogenous DNA into spermatozoa was completed within 90 min of incubation. In another experiment, there were significant (p<0.05) differences between transfected spermatozoa using both DNA solution and DNA/liposome complexes with untreated spermatozoa for viability (70.8±1.80 and 68.0±2.16% vs. 83.3±1.69%, respectively) and motility (78.7±1.59 and 79.3±2.14% vs. 86.7±1.59%, respectively). This study indicates that exogenous mtDNA can be efficiently transferred into boar spermatozoa regardless of the presence of liposome, and transfected spermatozoa can also use insemination and in vitro fertilization to generate transgenic pig.

Restless legs syndrome (RLS) is associated with dopaminergic dysfunction, and iron de ciency, manifesting as low ferritin. However, ferritin levels do not correlate well with demographic data. Based on the hypothesis that very low ferritin can accurately re ect clinical information, we herein described characteristics and treatment e cacy of RLS patients with ferritin levels under 15 ng/mL. We retrospectively reviewed 196 patients and collected clinical data. Twenty-one patients had ferritin levels under 15 ng/mL and were compared with those having ferritin levels over 15 ng/mL. e pa- tients with very low ferritin levels were predominantly female, had earlier onset of symptoms, and showed a superior response to iron therapy. In conclusion, RLS patients with ferritin levels under 15 ng/mL showed distinct demographic features and treatment e cacy. Further studies on more patients with long-term follow-up are warranted to support this observation.

Cloning and Characterization of Carboxylesterase (est2R) Gene from Cow Rumen Metagenomic Library

Tae-Ho Kang,Min-Keun Kim,Tae-Yang Kim,Gi-Hwan Kim,Jung-Ho Kim,Hoon Kim,Han-Dae Yun 경상대학교 농업생명과학연구원 2012 농업생명과학연구 Vol.46 No.3

The gene encoding an esterase enzyme was cloned from a metagenomic library of cow rumen bacteria. The esterase gene (est2R) was 2,120 bp in length, encoding a protein of 516 amino acid residues with a calculated molecular weight of 57,286 Da. The molecular weight of the enzyme was estimated to be 57,000 Da by SDS-PAGE. Est2R shared 35.6% amino acid identity with esterase (CAH19079) of uncultured prokaryote. The Est2R was most active at 20-40°C, and showed optimum at 30°C and pH 8.0. The most activity of Est2R for the different chain length of p-nitrophenyl ester group as substrate was p-nitrophenyl acetate. Moreover, the enzyme was found to be most active without organic solvent, followed by 98% active with ethanol, and the enzyme activity was highly affected by the acetonitrile. The enzyme was significantly inhibited by Zn2+ but stimulated by Ca2+. So, novel esterase gene est2R is likely to obtain from cow rumen metagenome and supposed to use for industrial purpose.

1970년대 대만 ‘향토문학(鄉土文學)'의 중층적 의의 구조를 통해 본 포스트 현대(後現代)와 포스트 식민(後殖民)

서로 다른 이해의 공간 컨텍스트(context) 아래에서 과연 이해한다는 것, 1930년대 『중국철학사』 심사에서도 등장했던 陳寅恪 의 '동정적 이해(理解之同情)'는 가능할까? 우리는 과연 대만이라는 일본의 식민지배와 국민당(KMT) 독재 통치하에서 성장한 역사, 문화 그리고 문학 공간에서 '정체성(identity)'을 찾아가려는 그들의 기나긴 노력을 제대로 이해할 수 있을까? 이러한 문제의식에도 불구하고 우리가 할 수 있는 것은 더욱 깊이 더욱 자세히 문제의 본질에 다가가려고 노력하는 것이며 그 과정에서 조금이나마 연구자인 우리의 노력이 한국 사회에서도 대만에 대한 진정한 이해를 조금은 돕게 될 것이라고 희망하는 것뿐일지도 모른다. 본 논문은 대만 문학 세계의 가장 중요한 이론적 충돌의 발화지점이라고 할 수 있는 1970년대 '향토문학' 논전 전후 드러나는 독특한 중층적 언어지표와 언어상징 구조를 자세하게 들여다보려고 한다. 특히 '향토문학' 관련 논전이 가지는 1930년대 일본 식민지배와 저항으로서의 탈식민(de-colonization) 그리고 1960~70년대 새롭게 제기된 모더니티 현대주의 문학과 이에 대한 현실주의 리얼리즘의 비판 그리고 이러한 중층적 의의 속에서 포스트 모더니티를 향한 '대만문학'의 가능성을 추적해보려고 한다. 또한 '향토문학논전'의 참여자들이 보여주는 복잡한 관계들의 문학사적 맥락에 주의하면서 대만문학의 일본 식민지배 시기 추구했던 탈식민 전통이 1970년대 '향토문학'과 어떠한 관계를 맺고 향후 '일본 신식민지배'에 대해 어떻게 포스트 현대와 포스트 식민을 향해 나아가는지 등의 문제들에 대해 그 이론적 지형을 확인해 볼 것이다. 이러한 접근을 통해 다른 문학적 상상과 목소리를 가지고 있는 '대만문학'의 정체성은 어디를 향해 가고 있는지를 이해할 수 있기를 바라며 또한, 동정적 이해가 조금이나마 가능하기를 바라본다. Is Chen Yin Ke 's idea roughly translated as 'understanding of compassion' appearing in the review report of the first volume of Feng You Lan's History of Chinese Philosophy in the 1930s still valid in different academic or cultural field contexts? Can we rationally, emotionally, or partially understand how important Taiwan's persistent endeavor is to find its own identity in the historical, cultural, and literary sphere that has grown up under the Japanese colonization and the Kuomintang dictatorship for a long time? Despite the awareness of this issue, maybe all we can do is get closer to the essence in a deeper and more detailed approach. In the process, we hope that our efforts and intentions as researchers can help Korean academic society a compassionate understanding of Taiwan identity pursuing and its difficult situation. This thesis attempts to grasp the unique multi-level linguistic indicators and language code structures that emerged before and after the Taiwan Nativist Literature debate in the 1970s. This debate can be the Taiwan literature core discourse struggles expanded to the cultural, social, and political levels and became the fuse of literary theoretical conflict. We should pay attention that the Japanese colonialism and de-colonization discourses in the Taiwan Nativist Literature debate in the 1930s were not only activated realistic criticisms to modernism in the 1960s but even in the literary and historical context of the complicated relationships shown by the participants of the Taiwan Nativist Literature debate in the 1970s. The tradition of de-colonization pursued by Taiwanese literature during the Japanese colonial period in the 1930s and the Taiwan Nativist Literature debate of the 1970s intricate complicate relations the multi-layered interpretative discourse struggles and theoretical conflicts between Taiwanese nationalism, left-wing nationalism, and right-wing nationalism directly affected whether Taiwan corrupted by the neo-colonial rule of the United States and Japan in the 1970s. With this self-reflection, these fierce debates and arguments have conducted a very rigorous test on how Taiwan literature and culture will move towards postmodernity and overcome postcolonialism in the future. Through this comprehensive understanding, surrounding the three main participants, Yeh Shyr-Tau, Chen Yingzhen, and Yu Guangzhong, we will hope that Korean academic circles can also be understanding with compassion the identity of Taiwan Literature, which has a different literary imagination and voice.
