2006년 5월부터 2007년 5월까지 동강의 어류상과 생태학적 군집분석을 조사한 결과는 다음과 같다. 조사된 어종은 총 10과 31종이었다. 총 31종의 어종 중 일차담수어가 26종, 주연성 담수어가 5종으로 나타나 일차담수어의 구성비가 매우 높았다. 우점종은 참갈겨니(Zacco koreanus) 55.73%, 아우점종은 쉬리(Coreoleuciscus splendidus) 7.15%였으며, 우세종은 배가시리(Microphysogobio longidorsalis) 6.12%, 어름치(Hemibarbus mylodon) 4.87%, 참종개(Iksookimia koreensis) 4.49% 등이었다. 한국고유종은 묵납자루(Acheilognathus signifer), 줄납자루(A. yamatsutae), 가는돌고기(Pseudopungtungia tenuicorpus), 쉬리(C. splendidus), 긴몰개(Squalidus gracilis majimae) 그리고 어름치(H. mylodon) 등 19종(61.29%)으로 고유종의 빈도가 매우 높았으며, 천연기념물이 1종, 환경부지정 멸종위기 야생동물 II급 종이 5종으로 각각 확인되었다. 예상되는 종수(기대종)의 분석 결과, 동강의 전 조사지점에서는 18(지점 4, 5)∼22종(지점 3)이 서식하고 있을 것으로 나타났으며, 유사도 분석은 62.28%(지점 1과 2)∼84.13%(지점 1과 5)의 범위로 나타났다. 따라서 동강유역은 어류가 서식하기에 매우 적합한 수환경을 유지하고 있으며, 각 조사지점별 수환경도 매우 유사한 것으로 판단된다. The ichthyofauna and ecological community analysis in the Dong River, Korea, were investigated from May, 2006 to May, 2007. During the surveyed period, 31 species belonging 9 families were collected. Total of 31 species(primary freshwater: 26 species, peripheral freshwater: 5 species) were found with the primary freshwater fishes being highest. Dominant species was Zacco koreanus(55.73%), and subdominant species was Coreoleuciscus splendidus(7.15%). Also, Microphysogobio longidorsalis (6.12%), Hemibarbus mylodon(4.87%), Iksookimia koreensis(4.49%) were numerous. There were 19 Korean endemic species(61.29%), including Acheilognathus signifer, A. yamatsutae, Pseudopungtungia tenuicorpus, C. splendidus, Squalidus gracilis majimae, H. mylodon. Among them, 1 species was identified as qualifying for possible desigantion as a natural monument catergory, and 5 species were identified for designation required to protect under a wildlife category. As result of expected number of species according to rarefaction curve, the expected species of the Dong-river ranged from 19(St. 4, 5) to 22(St. 3) and result of similarity analysis ranged from 62.28%(St. 1 and 2) to 84.13%(St. 1 and 5). In conclusions, we could define that the Dong-river has a very good water conditions as habitat of fish, and habitat conditions also are very similar in every survey sites.

김준우(Kim Jun Woo),김용구(Kim Yong Gu),전동진(Jeon Dong Jin) 인천대학교 인천학연구원 2018 인천학연구 Vol.29 No.-

본 연구는 신포동 젠트리피케이션 현상에 관한 연구이다. 인천의 중심지였던 신포동 지역은 1985년 시청 및 공공시설이 구월동으로 이전하고 인천시의 대규모 도시개발정착에 따라 낙후된 지역으로 변해갔다. 그러나 2008년부터 교육서비스업종, 창작 및 예술, 협회 및 단체 업종의 종사자 수를 보면 신포동이 다른 주변지역(연안동, 동인천동, 북성동)보다 크게 증가하고 있다. 같은 시기 신포동의 인구의 수는 계속 감소하는 반면에 부동산업, 교육서비스업종, 창작예술업종, 문화예술인들이 카페 등으로 등록하는 휴게음식점 종사자는 증가하고 있다. 중구지역 지가변동은 2008년부터 2012년 까지 감소하다가 2013년부터 증가한다. 2013년부터 지가변동율이 증가하자 휴게음식점업종 및 창작예술업종이 감소하고 있다. 연구 결과를 종합해보면 신포동의 인구의 수는 계속 감소하는 반면에 부동산업, 교육서비스업종, 창작예술업종, 휴게음식점 종사자의 증가하고 있으며, 2013년부터 지가변동율이 증가하자 휴게음식점업종 및 창작예술업종이 감소한다. 신포동은 2013년을 기점으로 젠트리피케이션 단계로 진입한 것으로 파악된다. This study is a study on the phenomenon of gentrification phenomena in Shinpo - dong. The Shinpodong area, which was the center of Incheon, was moved to Guwol-dong in 1985 when the city and public facilities were moved to Incheon. However, since 2008, the number of employees in the education service industry, creative arts, arts, associations and organizations has increased sharply compared to other surrounding areas (coastal dong, Dongchun-dong, and north-east). At the same time, the number of population in Shinpo - dong continues to decline, while the number of resting restaurants that real estate, educational service, creative arts, and cultural artists are registered as cafes is increasing. The fluctuation of Jungang area land prices will decrease from 2008 to 2012, but it will increase from 2013. As the land price volatility has increased since 2013, the rest restaurants and creative arts industries are declining. According to the results of the study, the number of population in Shinpo - dong continues to decrease, while the number of real estate, educational service, creative arts and resting restaurants are increasing, and the rate of change in land prices has increased since 2013. Shinpodong appears to have entered the gentrification phase starting in 2013.

Dong‑Jun Kwon,Sung‑Min Park,Il‑Jun Kwon,Joung‑Man Park,Euigyung Jeong 한국탄소학회 2019 Carbon Letters Vol.29 No.2

This study provides an economical and effective method to improve the interlaminar properties of carbon fiber-reinforced polymers (CFRPs) using aluminum trihydroxide (ATH) microparticles. ATH microparticles are cheap and are expected to show good affinity to epoxies in the matrix and sizing agents of the carbon fibers owing to the presence of three hydroxyl groups. In addition, ATH particles are reported to improve the mechanical properties of polymers when used as the reinforcement. In this study, ATH microparticles of various sizes, 1.5, 10, and 20 μm, were used to improve the interlaminar properties of the CFRPs. ATH particles with a size of 1.5 μm improved the tensile properties of the ATH/epoxy resin and did not significantly alter the curing behavior. The interfacial adhesion between the carbon fiber and the epoxy resin was also improved, and the impregnation of the resin mixture remained similar to that of the neat resin, resulting in no significant void and defect formation. Considering the above results, the resulting 1.5 μm ATH-reinforced CFRP showed improved interlaminar properties compared to CFRP without ATH. However, 10 and 20 μm ATH-reinforced CFRPs showed deteriorated interlaminar properties due to the diminished tensile properties of the resin itself and resin impregnation, which resulted in more voids and defects, despite the interfacial adhesion between the fiber and the matrix resin.

Background Sequence variations such as single nucleotide polymorphisms are markers for genetic diseases and breeding. Therefore, identifying sequence variations is one of the main objectives of several genome projects. Although most genomeproject consortiums provide standard operation procedures for sequence variation detection methods, there may be differencesin the results because of human selection or error. Objective To standardize the procedure for sequence variation detection and help researchers who are not formally trainedin bioinformatics, we developed the NGS_SNPAnalyzer, a desktop software and fully automated graphical pipeline. Methods The NGS_SNPAnalyzer is implemented using JavaFX (version 1.8); therefore, it is not limited to any operatingsystem (OS). The tools employed in the NGS_SNPAnalyzer were compiled on Microsoft Windows (version 7, 10) andUbuntu Linux (version 16.04, 17.0.4). Results The NGS_SNPAnalyzer not only includes the functionalities for variant calling and annotation but also providesquality control, mapping, and filtering details to support all procedures from next-generation sequencing (NGS) data to variantvisualization. It can be executed using pre-set pipelines and options and customized via user-specified options. Additionally,the NGS_SNPAnalyzer provides a user-friendly graphical interface and can be installed on any OS that supports JAVA. Conclusions Although there are several pipelines and visualization tools available for NGS data analysis, we developedthe NGS_SNPAnalyzer to provide the user with an easy-to-use interface. The benchmark test results indicate that theNGS_SNPAnayzer achieves better performance than other open source tools.

近代 韓國私學의 起源과 그 發展方向에 關한 硏究 : 政治文化的 側面을 中心으로

康東俊 건국대학교 1979 論文集 Vol.9 No.1

This study has relations with the history of the Yi dynasty, and of the modern education in Korea. But, it is neither the history of the Yi dynasty itself nor the history of the modern education in Korea. This study makes use the present results of the above·mentioned two disciplines, tries, to find out the aspect of political culture of the modern private schools, in terms of it's initial stage. In the first place, we understand the ertablishment of modern private schools in Korea, as the fourth attempt for the modernization of the Old Korea, The first attempt, before the open door policy of Korea, was taken by the progressive doctrinal movement within the framework of the confucian scholars based on the empiricism and pragmatism (the Sil-hak). The second, after the open door to the Japan, was the movement for the modernization of the Old Korea. The third attempt was the Revolt of Korean farmers (the Dong-hak) in 1894, before the war between China and Japan. Therefore, we consider the above-mentioned three movements as ideological background of the Korean modern private schools in terms of it's initial stage. In regard to the origins of the Korea modern private schools, Koreans have founded the schools, by their own fortunes, to fight in defense of their country, against the Japanese aggression by means of educating the people, whereas the mission schools have faunded by foreign missionary funds for the missionary works, based on the Christianism. In the meanwhile, the government of the Empire o Korea promulgated the Ordinance of the private schools in order to limit and control the private schools, while the students who learned the Japanese was increased, in the public schools, in great number. As for the development-orientation, reflected in the contents of teaching, the text books, the students' activities and, the popular songs for students, the major characteristics are as follows; First, such feeling as "I am the master of the country" is advocated intensively, but previously the king or the noble was the master, not the people; this is the radical change of idea. We find here a very sincere reflection of the relation between the individuals and the state. Second, the teachers and the students reproached openly the Japan for it's aggression and the government for it's powerlessness. Therefore, the Japaneses blamed the Korean private schools for being confused. the education with the politics and for the penetration of the "seditious idea" into the private schools. Hereafter, this anti-Japan orientation, changed in the anti-government orientation, became the resistance-orientation against the political power. Third, the establishment of the girls schools proved the break down of the traditional inequality of two sexes, the children of the noble and the common people learn together to approve the abolishment of the carte system. Moreover, the school for deaf and mute was founded. Here, we find the orientation for the equality among people. These political orientations, without a doubt, are found to be the efforts of criticing and overcoming the confucian tradition by which the Korean political tradition can be characterizel by it's authoritarian political culture, in which people were made subservient to the state through the requirement of loyalty. Certainly, the activities of the Korean modern private schools belong to the same category of the efforts put out by Sil-hak philosophy, Dong-hak philosophy, Modernization Movement and Independence Association Movement, and these efforts are considered to be the movements by the people to establish national identity and to promote equality within the society. In spite of the political and social visissitude, it is to be remembered that the originality of the aspect of the political culture, in the Korean modern private schools, consists in it's institutional continuity, that is, the continual development of the Korean private schools.

Objectives: The purpose of this study is to investigate interaction and safety in administering herb-medicine with warfarin. Methods :For this study, we selected 19 patients who have been taking warfarin, from the ones that have been transferred from western hospital to oriental hospital. During their stay in the oriental hospital, we gave herb-medicine in addition to warfarin. Then we gathered informations and data on sex, age, main indications, and International Normalized Ratio(INR) values of selected patients through Electronic Medical Records(EMR) of Dong-Guk university hospital. Accordingly, we compiled all of the above data for a period of 10 days prior and 10 days post admission(western hospital period and oriental hospital period, respectively)Results and Conclusions :The statistical analysis of the data have revealed that there was no significant change of INR values after giving herb-medicine with warfarin(p=0.586). The result shows that administration of herb-medicine with warfarin is safe and has little drug interaction. However, this study was carried out on small sample size and the interaction with other drugs and various kinds of herb-medicine was not considered. Although we attained a restrictive result from this study, we are able to suggest the safety about co-administration of herb-medicine and warfarin.

The critical power(CP) is the highest intensity to sustain for a long time without a fatigue. The anaerobic work capacity(AWC) is the highest anaerobic capacity to be provided by anaerobic energy system without the infection of hypoxia. The purpose of this study was to determine the relationship between AWC and AnP and to verify the validity of AWC. The subjects were consisted of 10 elementary and 10 middle school male students(12.8±1.3yrs, 159.3±12.1㎝, 49.4±11.8㎏). The critical power and anaerobic work capacity were calculated by work-time relationship after four cycle ergometry test to fatigue from 1 to 10 minute. The anaerobic power included Margaria-Kalmen test, Sargent jump and Wingate test. The main finding were as follows. The AWC of elementary and middle school students. were 6.47±2.63KJ and 11.10±3.01KJ. The AWC of elementary students was 58.3% of the middle school students's one. The AnP of elementary students were 47.2∼66.5% of the middle school students's one. And there were high correlation between AWC and AnP(0.64∼0.87, P<0.01). This study showed that AWC is useful index on AnP both elementary and middle school students.

DNA 포렌식에 의한 DNA 증거의 증거능력에 관한 고찰

김동준(Kim, Dong­Jun),오경식(Oh, Kyung­Sik) 한국피해자학회 2018 被害者學硏究 Vol.26 No.1

Advances in forensic DNA analysis have led to tremendous improvements in identifying and confirming perpetrators and victims. This has added credibility to DNA evidence, resulting in cases where criminals are more likely to be forced to own up to their criminality and culpability. This paper addresses scientific and technical theories the DNA analytical technologies are founded on as well as the suitability of individual analytical procedures. Beyond these issues, it went on to discuss the requirements that need to be met in order for DNA evidence, collected through forensic DNA testing, to be admissible in court in Korea. DNA testing results are presented in court in the form of certified expert testimony. And according to Article 313, “Statement, etc.” of the Criminal Procedure Act, as long as the DNA evidence offered is free from errors in laboratory procedures and concluding interpretations of the person responsible for producing the expert opinion recording, such procedures and outcomes will be admissible as legitimate evidence in court. In other words, the aforementioned expert testimony is nothing short of legislative intent at acknowledging the testimony as admissible in court, thus should not be understood as standards with which the scientific evidence concerned is admissible and tried at court. For this reason, admissibility in court of DNA evidence from DNA forensic analysis should not only be based on whether it meets the requirements as expert testimony, but also whether its theories of reasoning and analyses are founded on acceptable scientific principles. Furthermore, the tools and methods used in DNAprofiling need to be validated, allowing the analyzed result in question to be assessed for admissibility in criminal court. Trends of precedents regarding DNA evidence seem to require that the relevancy of DNA analytical theories, suitability of DNA analytical methods that have implemented these theories, and maintenance of the chain of custody of evidence by applying scientific procedures to the targets concerned, be met for the evidence to be admissible in court. Furthermore, it may be fair to say that within the structure of Korea’s criminal prosecution, the processes involved in determining whether or not DNA evidence is credible may be part of what is needed to assess its probative value. At the moment, theoretical foundations of DNA analysis are deemed reliable with the overall approval of scientific circles, however there are improvements made all the time in standard analytical methodologies and procedures regarding their implementation and analytical techniques. This has created an unbridgeable gap between common knowledge and the outcomes of scientific research activities that legal experts, particularly trial judges, are left with no choice but to be more and more dependent on expert testimony when they assess the credibility of DNA evidence. Still, the more weight DNA analysis carries, the more likely serious errors in laboratory testing occur; thus, there is increased emphasis on how to keep the chain of custody in determining the admissibility of DNA evidence, for example, the qualification of those involved in testing, sample collection and preservation, stability of the testing methods that have been utilized, and conformance to analytical procedures. Therefore, if there is evidence that is crucial in determining guilt in crime, and the continuity of its preservation is closely related to the presence and integrity of the evidence concerned, namely DNA evidence, the defendant should be afforded the opportunity for the credibility of evidence to be tried in court during the entire processes of such evidence being collected, stored and analyzed to: prevent wrongful accusations; to make court proceedings more impartial; and to comply with appropriate procedures. To this end, cross examination of witnesses, disclosure of extensive evidence of the parties involved, and cross examinat

자연농지로 30년간 휴농되었던 장단군 장단면 반정리, 간사지였던 화성군 장안면 수촌리 및 독정리, 또한 간사지를 1976년 개간한 팽택군 청북면 삼계리에 2개처, 계 5개처를 택하여 각각 5개의 논들을 2~3년간 대상으로 삼았고, 데조로 한 관행농지로는 전기 반정리 외에 팔당댐 상류인 양주군 와부면 능내리 및 하류인 팔당리, 안양천 물로 관개하는 서울특별시 강서구 목동, 한강물로 관개하는 김포군 고촌면 신곡면 등에 있는 각각 5개의 논에서 2~3년간 계속 현미를 취하였다. 이들 현미 중에 함유되어 있는 수은, 카드뮴, 연 등 중금속을 공해공정시험법에 따라 분석한 결과는 다음과 같다. 1) 일반적으로 자연농 현미의 수은 검출치가 관행농의 그것보다도 낮아서 자연농 평균 0.0008ppm, 관행농 평균 0.013 Since 1977 the heavy metals, i.e. mercury, cadmiyn and lead, have been analyzed for 3 suc-cessive years in the borwn rice on the organic farming in Ban Jung_1, Soo Chon, Dok Jung, Sam Ke_1 and Sam Ke_2 as well as on the conventional farming in Ban Jung, Nung Nae, Pal Dang, Mok Dong and Shin Kok. The results of the invesrigation are summairzed as follow: 1. The mercury content on the organic farming, average 0.0008SE±0.0002ppm, is significantly lower than the conventional farming, average o.013±0.002ppm. The mercury has the tendency of lowering every year in both the organic farming and the conventional farming. 2. The cadmium on the organic forming is average 0.217 ppm, and the conventional farming average 0.257 ppm. The cadmium in Mok Dong on the conventional farming shows higher level than elswhere, over 1 ppm. 3. The lead on the organic farming is average 0.579 ppm and average 0.535 ppm on the conventional farming also shows higher level, over 2 ppm. It is supposed that the acceptible tolerance of mercury in brown rice is to be 0.043 ppm; while, the cadmium and lead are temporality 1 ppm.
