開化期의 學術誌에 나타난 韓國政治思想에 관한 硏究

宋二朗 東亞大學校 1981 東亞論叢 Vol.18 No.1

The formation of modern Korean political thoughts may be said to have been established with, mainly, a view to self-defending and self-reformation against the impacts of the western material and technical civilization that had come into the nation since the nineteenth century. Therefore, the success of the formation of the modern poltical thoughts was possible only when the nation maintained both national identity and modernization that do not usually accord with each other characteristically. From this point of view, we may say that roles of academic journals published between 1905 to 1910 were very important because, Firstly, they served to create modern nationalism. The advocation of recovering sovereignty, such as they had done, served as the unifying point of the people that has homogeneous ideology rather than simply returning to the absolute monarchy we had in the past. Secondly, they contributed to forming modern democratic thoughts. These journals asserted that losing sovereignty meant not only collapse of the monarchy itself, but also the self-forfeit spirit of the people. Therefore, the journals emphasized education and industry as the only possible way to awaken people to reality. At the same time, these journals advocated adopting democratic political system into the nation by guaranteeing freedom and equality of the people. Thirdly, they contributed to popularizing modern political thoughts among people. They attempted forming political thoughts of the national identity and selfdetermination by gradual practices of modernizing people's way of thinking through education. Fourthly, they contributed to unifying national identity and modern progressivism. The movement of nationalism in Korea, like western one, influenced people with unifyed concerted idea of the people which gave an impetus to executing democracy. For these reasons, the roles and activities of these journals during the enlightenment period strongly influenced in forming modern political thoughts in the nation by arousing consensus among all the levels of people through overcoming limitation set on the traditional functions of the mass media and greatly influenced in forming the idea of 3·1 Independent Movement in 1919 finally.

北韓體制에 있어서 神話

송이랑,김경호 東亞大學校 2002 東亞論叢 Vol.39 No.-

This study is trying to detail things about North Korea through the legend of it. The legend is a kind of belief which is not based on the truth. The political legend is simply a fiction about things political. The system of North Korea has kept nervous since the beginning. As a result, it has focused on keeping the system rather than develops the country. This structural-character caused the legend. Especially the legend in the system of North Korea played the definite role in keeping the system of kim, IL-Sung and electing the successor.

조선후기의 사회구조적 변화와 대원군의 정책

송이랑,김경호 東亞大學校 2000 東亞論叢 Vol.37 No.-

The purpose of this paper is to analyze and evaluate changes in social structure in the latter period of Chos?n and Daewongun's policies. During his rule, externally, the World Powers were eager to expand their imperialistic policies. Internally it was time for Chos?n to choose a new direction in history, largely due to the changes in the social structure. From an integrative point of view on structure and act rather than dualistic point, the paper examined the structure of ideology, status, agriculture, and commerce in the later Chos?n and then examined the relations between Chosen and Chung, between Chos?n and Japan, and between Chos?n and Western powers, respectively. Under such circumstance, in 1863, King Kojong ascended the throne Cheoljong and, immediately, Daewongun took the reigns of government. He tried to clean up deep-rooted evils caused by royal-married families(Sedojunchi), and to rule over the nation flexibly enough to accommodate various social changes. Accordingly, he promoted various policies in order to establish a new domestic order by way of overall social reforms. politically, Daewongun solidified his power basis and adopted merit system to allow more opportunities for the talent. His policies may be evaluated by three criteria - the will of ruler, support base, and the atmosphere of the times. Daewongun met two necessary conditions: leader's will on reform and possession of supporter groups. Nonetheless, his reformative policies can be evaluated as an half success because of premature social atmosphere to accommodate his reformative will. Thus, we come to conclusion that for the successive promotion of Daewongun's policies the three conditions must be worked out on mutual balance.

The results of this Study are as follows:33.6% of all participants have insomnia; 22.5% of those who have insomnia are DIS(difficulty in initiating sleep), 17.3% are DMS(difficulty returning to sleep once awakened) and 7.0% awakened too early. 3 4.8% experience sleepiness during daytime. Type 1, experiencing insomnia and sleepi ness during daytime together, is 12.0%, Type 2, with insomnia only, is 21.6%, Type 3, with sleepiness during daytime only, is 22.8% and 43.5% experience no sleeping disturbances. After studying only those with 3 types of sleeping disturbances, it is found that the most common cause of such disturbance is stress 88.4%, anxiety 56.0%, no apparent reason 33.8%, anxiety/fear/terror 29.3%, hurry 23.6%, alcohol/caffeine 16.9%, bedroom tem perature 11.1%, urination during nighttime and persons living together 10.7%, noise from inside 8.9%, illumination 8.0%, and pain/itch 5.8%. The one group revealed significant differences in residential environment(p=0.003). Sex, age, education level, medicine, monthly earning revealed no meaningful differences. Of sleeping behavior, mean duration of sleep latency(p=0.000), whether or not feeling freshness(p=0.000), whether taking enough sleep(p=0.029), whether taking regular sleep(p=0.005) showed significant differences depending on whether or not having insomnia, and mean duration of sleep time, time to sleep, time of rising, whether taking naps did not reveal significant differences. Of sleep behavior, time to sleep(p=0.000), whether taking naps(p=0.000), indicated significant differences. Of sleeping behavior, mean duration of sleep latency(p=0.000), whether or not feeling freshness(p=0.000), and whether taking enough sleep(p=0.000), time of going to bed (p=0.002), whether or not taking nap(p=0.000), whether or not taking regular sleep(p=0.010) indicated significant differences among the sleeping disturbance types.

Estimating spatial patterns of air temperature at building‐resolving spatial resolution in Seoul, Korea

Yi, Chaeyeon,Kim, Kyu Rang,An, Seung Man,Choi, Young‐,Jean,Holtmann, Achim,Jä,nicke, Britta,Fehrenbach, Ute,Scherer, Dieter John Wiley Sons, Ltd 2016 International journal of climatology Vol.36 No.2

<P><B>ABSTRACT</B></P><P>The thermal environment in urban areas is substantially influenced by local surface properties and their modification through human activities. The effects of urban climate on human health are one of the motivations for the development of various urban climate analysis tools. Climate Analysis Seoul (CAS) is a tool that incorporates a meso‐scale atmospheric model and conceptual geographic information system (GIS)‐based models to provide gridded air temperature deviations based on high‐resolution land cover information. The CAS output was evaluated using air temperatures observed at 18 automatic weather stations (AWS) located in the detail region (DR) Eunpyeong. Correlation analyses were performed to reveal the influence of different land cover characteristics and CAS output variables on measured air temperature deviations. Based on the results of the correlation analyses in the study region (SR) Seoul, a regression model (total air temperature distribution, TD′) was developed. It predicts spatially distributed air temperatures based on morphological parameters and an observed reference temperature. Using the TD′ model, maps of daily maximum air temperatures were produced for the entire area of Seoul with a horizontal resolution of 25 m, and of 5 m for the DR, the latter allows to assess the impacts of different building and vegetation structures on air temperature by resolving buildings. The TD′ model was evaluated using measurements at eight AWS. The TD′ model slightly overestimated daily maximum air temperatures in 2007 and 2011, but performed better for 2011, mainly because land cover data represent the final state of the urban development. The TD′ model appears to be a suitable tool for estimating air temperature distributions at building‐resolving resolutions. It can be used to assess changes in the thermal environment and heat‐related hazards through urban development plans already ahead of their realization.</P>

Objectives : The purpose of the present study was to investigate the association between -1438A/G polymorphism of 5-HT2A receptor gene and schizophrenia in Korean and Han Chinese population. Methods : A sample of 184 Korean patients with schizophrenia and 96 Korean healthy normal controls and 96 Han Chinese patients with schizophrenia and 96 Han-Chinese healthy normal controls were genotyped for a single nucleotide polymorphism with in 5-HT2A receptor gene (promoter region, A-1438G) by Msp I Resthction Fragment Length Polymorphism (RFLP). Results : There was no difference in allelic frequencies and genotype frequencies of -1438A/G polymorphism between Korean schizophrenics and controls (p=0.13) and Han Chinese schizophrenics and controls (p=0.40). Also, -1438A/G Poly-morphism did not show ethnical difference between Korean and Han Chinese controls. The Scale for the Assessment of Negative Symptoms (SANS) scores showed no significant differences between genotypes of -1438A/G polymorphism in both of Korean and Han Chinese schizophrenics. Conclusion : These results suggest that -1438A/G polymorphism of the 5-HT2A receptor gene is not causally related to the development of schizophrenia in Korean and Han Chinese population, and there no ethnic difference between Korean and Han Chinese population.

Pro-oxidant 3,3`,4,4`,5-pentachlorinated biphenyls 126 (PCB126) is a global environmental contaminant that can induce cellular oxidative stress. Disruption from cellular oxidative stress can be blocked by several nutrient antioxidants like vitamin E. We used the fish model, zebrafish (Danio rerio), to determine if vitamin E can protect against toxicity from the aryl hydrocarbon receptor (AHR) ligand PCB126 during zebrafish development, and to show the mechanism by which PCB 126 induces toxic effects. We exposed zebrafish embryos at 8 hours post fertilization (hpf) to PCB126 at a concentration of 100 nM, and compared these fish with a second group that was co-exposed to 100-μM vitamin E and 100-nM PCB126 until 5 days post fertilization (dpf). PCB126 induced pericardial sac edema, yolk sac edema, heart malformation, hemorrhaging, failure of swim bladder inflation, growth retardation and mortality in developing zebrafish larvae. In contrast, 100-μM vitamin E co-exposure did not induce the gross changes seen in the PCB126 treatment group. We found that vitamin E can protect against PCB126 toxicity by inhibiting zebrafish heat shock protein 70 cognate (zfHsc70) down regulation. Also vitamin E inhibited the zebrafish aryl hydrocarbon receptor type-2 (zfAHR2), zebrafish cytochrome P450 1A (zfCYP1A), zebrafish superoxide dismutase-1 (zfSOD1) and upregulated zebrafish superoxide dismutase-2 (zfSOD2) mRNA expression. These data give insights into the use of vitamin E to reduce PCB126-mediated toxicity and into the use of zebrafish embryos for exploring mechanisms underlying the oxidative potential of AHR agonists.

Transcriptional repression of Type Ⅰ procollagen genes during adipocyte differentiation

Yi, TacGhee,Choi, Hee-Man,Park, Rang-Woon,Sohn, Kun-Young,Kim, In-San 경북대학교 병원 2002 경북대학교병원의학연구소논문집 Vol.6 No.1

Adipocyte differentiation is a very complex process in which whole-cell changes are accompanied.Among them, type I procollagen gene has been shown to specifically decrease during adipocyte differentiation; however, little is known about the molecular mechanism. To examine how type I procollagen gene expression is regulated at the level of transcription during adipocyte differentiation,3T3-L1 preadipocyte cell line was used as an in vitro model.Northern blot analysis demostrated that mRNA expression of type I procollagen gene was dramatically reduced during adipocyte differentiation. Time-course analysis indicated that decrease in mRNA expression occurred at early stage of differentiation. Studies on several stable cell lines showed that transcriptional activities of both α1 and α2 promoters decreased significantly during adipocyte differentiation.Despite extensive deletion-promoter analyses, however, we could not identify the cis-element responsible for the switch-off of type I procollagen bene during adipocyte differentiation, suggesting that the transcriptional repression of this gene occur through general transcriotion machinery rather than a specific cis-element. In conclusion, down-regulation of type I procollagen mRNA expression during adipocyte differentiation is due to repression of its promoter activity through general transcription machinery.
