This study was performed to prepare the Korean unification on the basis of analyzing systematically the relationship between the psychological and economic indices after the unification in Germany. Germany, though 17 years passed since the unification, still has unification sequelae in psychological aspects and its major causes is supposed as economic problems. So we focused on the psychological indices and economic indices measured in Germany for 11 years from 1991 to 2001, and analyzed the relationship between them variously. At first, as economic indices, GDP growth rate, unemployment rate, income, pension benefit, consumer prices, tax-bearing rate, budget transfer to the East Germany, and cumulated budget transfer to the East Germany were selected, and as psychological indices, life satisfaction and income satisfaction were chosen. Then we analyzed the trends of these indices and performed the correlation analysis between the economic and psychological indices. The results are followed. That is, life satisfaction and income satisfaction are not significantly correlated with GDP growth rate, but they are significantly correlated with unemployment rate, income, pension benefit, and consumer prices. So we can conclude from these results that the national entire economic magnitude itself does not increase psychological well-being such as life satisfaction and income satisfaction, but other economic indices connected closely with people's daily life are more important in psychological satisfaction and well-fare. Finally, we were able to identify that life satisfaction and income satisfaction of the West Germans and the East Germans were influenced by different factors 본 연구는 독일이 통일된 후 17년이 경과된 시점인데도 아직까지 심리적 인 측면에서 통일 후유증을 앓고 있다는 점과 그 주된 원인이 경제적 문제 이라는 지적에 착안하여 이들의 관계를 체계적으로 분석하여 향후 통일 한 국을 위한 준비를 제대로 하려는 관점에서 이루어졌다. 이를 위해 통일 이 듬 해인 1991년부터 2001년까지의 11개년에 걸쳐 측정되거나 작성된 경 제 지표와 심리 지표를 활용하여 분석하였다. 먼저, 경제 지표로는 GDP(Gross Domestic Product) 성장률, 실업률, 소득액, 연금액, 소비자 물가 변동 률, 담세율, 동독으로 재정 순이전액, 동독으로 누적 재정 순이전액 변수를 선택하였고, 심리 지표로는 생활만족도와 소득만족도를 선택하였다. 이들 각 지표들에 대해 변화 추이를 파악하는 것을 1단계로 실시하고, 경제 지표들 과 심리 지표들 간의 상관분석을 2단계로 실시하였다 연구 결과, 전체 독일인에서는 생활만족도와 소득만족도 간에 상관관계가 유의미하지 않았으나, 서독출신자와 동독출신자 각각에서는 이들이 유의미 하게 높은 정적 상관을 보였다. 그리고 전체 독일인에서는 생활만족도는 GDP 성장률과 상관관계가 유의미하지 않았고, 실업률, 소득액, 연금액, 소 비자 물가상승률과의 상관관계가 유의미함을 알 수 있었다. 이러한 결과는 통일 국가에서 단순히 국가 경제 규모가 증가하는 것만이 국민들의 심리적 만족을 증가시키는 것이 아니라 국민들의 피부에 와 닿는 경제지표가 더 중 요함을 의미한다. 마지막으로, 서독 출신자와 동독 출신자는 각각 상이한 요인에 의해 생활만족도가 영향받았음을 확인하였다. 따라서 국가 경제 규 모와 같은 거시적 지표만으로 통일의 효과를 호도하는 일이 없어야 하고, 국민 개개인의 입장에서 통일의 효과를 논해야 한다는 점이 무엇보다도 중 요하다는 것을 알 수 있다.

LB-9, Novel Probiotic Lactic Acid Bacteria, Ameliorates Dextran Sodium Sulfate-Induced Colitis in Mice by Inhibiting TNF-α-Mediated Apoptosis of Intestinal Epithelial Cells

채정민,장문한,허완,조형택,이동훈,황보별,김진우,윤석민,양시영,이진협,김영준 한국식품영양과학회 2019 Journal of medicinal food Vol.22 No.3

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease, is a group of chronic and relapsing inflammatory conditions within the gastrointestinal tract. An increase in intestinal epithelial cell (IEC) apoptosis is a major characteristic of UC. Tumor necrosis factor-α (TNF-α) plays an essential role in the regulation of apoptosis. Aberrant activation of the immune response to resident microflora contributes to overproduction of TNF-α in the mucosal tissue of the gastrointestinal tract; a hallmark of UC. There are no curative medications for IBD. Thus, establishment of novel strategies for the treatment of this disease is imperative. Lactic acid bacteria (LAB) have been characterized as probiotics that can alleviate imbalances in indigenous microflora in UC, exhibiting beneficial effects for the treatment and prevention of IBD. In this study, we elucidate the potential of LB-9, a novel probiotic LAB, to protect against colitis development using a dextran sodium sulfate (DSS)-induced mouse model of UC. Treatment using LB-9 reduced clinical symptoms of colitis. In addition, both colitis-induced and NF-κB-mediated IEC apoptosis was markedly reduced in mice treated with LB-9. Moreover, these results were closely associated with reduced TNF-α levels. Our study demonstrates that the LB-9 probiotic exhibits therapeutic potential for UC through suppression of TNF-α-mediated IEC apoptosis in a murine DSS-induced colitis model, with important biological implications for treatment of IBD in humans.

대장폐색을 유발한 식물위석 1예

채정민,차재명,이정일,주광로,김선용,조욱,김민경,유정선 대한소화기내시경학회 2011 Clinical Endoscopy Vol.42 No.1

Colonic phytobezoars are defined as conglomerate masses of fruit or vegetable matter in the colon, and these have rarely reported as a cause of colon obstruction. Because it is extremely rare, its correct diagnosis might be delayed even with the aid of abdominal computed tomography. We report here on a case of diagnosed colonic obstruction due to colonic phytobezoars in a 67-year-old female with diabetic end stage renal disease and chronic constipation. Although abdomino-pelvic computed tomography did not demonstrate the presence of phytobezoars, multiple phytobezoars impacted in the colon were found and these were removed by colonoscopy. This is a rare case in that colonic obstruction due to phytobezoar was diagnosed early and it was treated by colonoscopy. 과일이나 식물 덩어리들이 뭉쳐서 종괴를 형성하는 식물위석은 대장폐색의 매우 드문 원인이다. 대장 식물위석이 매우 드물고 분변 종괴로 오인할 수 있기 때문에, 복부 전산화단층촬영의 도움에도 불구하고 정확한 진단이 지연되어 심각한 합병증이 유발 될 수 있다. 저자들은 당뇨병성 말기신부전과 만성 변비를 가진 67세 여자에서 식물위석으로 인한 대장폐색을 대장내시경으로 진단한 증례를 보고한다. 본 증례는 복부 전산화단층촬영에서 식물위석을 진단할 수 없었지만, 대장내시경을 이용하여 대장에 박혀있는 다발성 식물위석을 진단하고 제거할 수 있었다. 식물위석에 의한 대장폐색을 대장내시경 검사를 통해 조기에 진단하고 치료하여 수술적 치료를 피할 수 있었던 증례를 문헌고찰과 함께 보고한다.

ZrB2-SiC 세라믹스의 미세구조와 기계적 물성에 미치는 B4C 첨가효과

채정민,이성민,오윤석,김형태,김경자,남산,김성원 한국세라믹학회 2010 한국세라믹학회지 Vol.47 No.6

ZrB2 has a melting point of 3245oC and a relatively low density of 6.1 g/cm3, which makes this a candidate for application to ultrahigh temperature environments over 2000oC. Beside these properties, ZrB2 is known to have excellent resistance to thermal shock and oxidation compared with other non-oxide engineering ceramics. In order to enhance such oxidation resistance, SiC was frequently added to ZrB2–based systems. Due to nonsinterability of ZrB2–based ceramics, research on the sintering aids such as B4C or MoSi2 becomes popular recently. In this study, densification and high-temperature properties of ZrB2-SiC ceramics especially with B4C are investigated. ZrB2-20 vol% SiC system was selected as a basic composition and B4C or C was added to this system in some extents. Mixed powders were sintered using hot pressing (HP). With sintered bodies, densification behavior and high-temperature (up to 1400oC) properties such as flexural strength, hardness, and so on were examined.

Preparing the unification of Korean penisula that would come up to unexpectedly, it is important to search the conflicts of political community come to existence and its solution methods in Unified Korea. After unification, North Koreans will drop in severe ideological conflicts by problems of recognition and adaptation about the system of liberal democracy and market economy, and it will be assumed that South Korea will take the leadership of unification, needless to say, the sense of superiority and inferiority of South and North Koreans and inequal distribution of human and material resources will bring about conflicts between South and North Korean territories. Also after unification, former industrialists, laborers and the middle classes of South Korea and executive members of the party, higher officials and the general public of North Korea will bring about class conflicts one other according to their interests. And in the political and economic situations pursuited by Unified Korea, there would be conflicts between young and accomplished generation in accordance with the degree of accepting its situations. By the political plans to be dissolved such various conflicts of political community, the form of goverment of Unified Korea will have to be parliamentary cabinet system and its parliamentarism will take bicameral system. As electoral system, it would be better that the majority system keeps pace with proportional system. Also political elite recruitment system of Unified Korea must be open and impartial. Unified Korea have to practice political education about fundamental ideas and principles of liberal democracy to North Korea inhabitants. So participant civic culture will fix soon in their political life. So, to minimize the various conflicts between south and North Korea, interchanges and cooperations have to be frequent before unification each other. And in the process preparing the unification, South Korea must exclude authoritarianism, foul, spoiling and regional complications, and North Korea also must pursuit the reformation and opening system and come to the place of dialogue with South Korea soon.

탈냉전 시대의 핵확산 가능성과 한국의 핵정책

채정민 대구효성가톨릭대학교 1996 연구논문집 Vol.53 No.1

Korea, being the interesecting region of the strategic interest of nuclear armed nations United states, China and Russia and of potential nuclear nation Japan, and also standing face to face with nuclear suspicious North Korea recognition of nuclear and its policy are the problems of connecting directly with the fate of our race and nation. There are primary factors of nuclear proliferation contantly because of insurance of self-help for the national security in spite of subsistance for the factors of nuclear non-proliferation after the Cold War. Beside United States, France, Great Britain, Russia and China, those are nuclear powerful countries, Israel, India and Pakistan and so on are recognized nuclear armed nations powerful coutries could not arrest those denuclear nations become nuclear nations. Japan arrived at the phase that could product the nuclear weapons already if he intend to, North Korea entread the process of succeeding performance of United States and North Korea nuclear agreement playing the nuclear game with United States after North Korea gave clinged to exploit the nuclear weapon. But it is the situation that many issues about nuclear can be protruded by Not고 Korea according to his past behaviors so far. And NPT system contracted 1968, could not have been performed the rolls of effective nuclear non-proliferation because, there are structual inequalities that nuclear powerful coutries are permitted to have nuclear weapons only and nuclear potential nations evade to enter the NPT system. In these tendencies of nuclear proliferation, Russia and Japan admitted the United States nuclear policy to North Korea that takes no notice of its past nuclear, and China support still North Korea. Now, South Korea must reexamine the denuclearized policy that has been pursued up to date and estavlish resolute and new nuclear policy. Joint Declaration of Denuclearization of the Korean Penisula proved a dead letter already as a fabrication, because North Korea had been possessed nuclear reprocessing and uranium enrichment facilities. So South Korean nuclear poicy have to ve like that he shall not possess nuclear weapon but shall extend the right of usage of nuclear energy for peaceful purposes and possess nuclear option. At last South Korea must assert a Nuclear-Warpon-Free-Zone in Northest Asia as long period nuclear policy of it.
