한국헌,김진호,이종식,이정택,조재영,윤광식 한국환경농학회 2005 한국환경농학회지 Vol.24 No.1

한정된 수질자료를 이용 오염부하 산정시 집중적으로 많은 샘플을 채취한 경우에 비해 어느 정도 차이를 갖는지를 규명하는 것은 모니터링에 따른 오염부하량 산정결과의 신뢰 범위 파악뿐만 아니라 경제적인 수질 샘플 채수빈도 수립에 곡 필요한 것으로 사료된다. 그 결과를 요약하면 다음과 같다. 논에서의 강우-유출시 채수 빈도가 오염부하 산정에 미치는 영향을 파악하기 위해 9개의 강우사상에 대해 2시간 간격으로 연속 수질샘플을 실시하여 분석한 결과 전체적으로 강우-유출과정 중 T-N, T-P, SS 농도는 시간별로 증·감변동을 하였으나 유량과의 상관성은 나타나지 않았다. 수질샘플 횟수에 의한 영향은 강우-유출과정 중 5회 정도 샘플을 실시하면 많은 수의 샘플을 채수한 경우에 비해 T-N ±15.2%, T-P는 -20.0~26.2%, SS는 -28.6~35.7% 범위안에서 오염부하를 추정할 수 있는 것으로 나타났으며, 차이범위가 ±10% 내에 들어가기 위한 샘플수는 일주기 조사시 T-N, T-P의 경우는 6회, SS의 경우는 단기유출시는 4회 정도 실시하면 되고, 장기 유출시에는 11회 정도 실시하면 되는 것으로 조사되었다. 유량-유하부하량 관계식으로 ±10%내의 차이를 보일 샘플횟수는 T-N의 경우는 6회 이상, T-P와 SS는 9회 이상 정도 실시하면 되는 것으로 조사되었다. In order to examine effects of sampling frequency during rainfall-runoff process from paddy field on the estimation of pollution load, EMCs of several water sampling frequencies were examined. Water quality samples were conducted by every two hours interval for each event. It was found that difference of load estimation between five times sampling and two hours consecutive sampling during rainfall-runoff showed 15.2~-15.2% for T-N, 20.0~-26.2% for T-P, 28.6~-35.7% for the SS, respectively. In the same way, the effects of number of sampling data on estimation of pollution load using runoff-mass load(L-Q) method were investigated. L-Q equation made of five times sampling data provided 10% differences in estimation of mass loads of T-N, T-P, and SS when compared to those by L-Q equation using entire two hours consecutive sampling data during runoff process.

Chitosan과 Chitooligosaccharides의 응집성

박헌국 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.6

Chitosan을 Bacillus pumilus BN-262 유래의 chitosanase로 처리한 경우에는 tnmer, tetramer, pentamer가 전체 올리고당 중 64.3%에 달하는 비교적 저분자의 chitooligosaccharides로 구성된 chitooligosaccharidesⅠ을 얻을 수 있었다 그러나 Trichoderma viride 유래의 chellulase로 처리한 경우에는 중합도 7 이상의 것이 전체 올리고당 중 49.3%에 달하는 상대적으로 분자량이 큰 chitooligosaccharides로 구성된 chitooligosaccharideⅡ를 얻을 수 있었다. 따라서 생리적 기능성이 높은 hexamer 이상의 chitooligosaccharides를 얻기 위해서는 chitosanase의 처리 조건을 달리하여 분해가 덜 일어나도록 하거나 cellulase와 같은 효소를 처리함으로써 chitosan의 부분적인 분해를 유도하는 것이 필요하다고 판단되었다. Chitin과 chitooligosaccharides의 응집성에 대하여 조사하였다 고분자의 chitosan은 2가 음이온을 함유하는 무기화합물 및 고분자의 유기화합물과 반응하여 응집이 일어났다. 분해가 많이 일어난 chitooligosaccharideⅠ은 무기물질과는 침전하지 않았으나 고분자화합물을 함유하는 유기화합물과는 반응하여 침전이 일어났다. 분해가 적게 일어난 chitooligosaccharideⅡ는 2가 음이온을 함유하는 무기화합물 및 고분자의 유기화합물과 반응하여 침전이 일어났다 Chitooligosaccharides were prepared by enzymatic hydrolyzing of crab shell chitosan. Low molecular weight chitoohgosaccharide Ⅰ, 64.3% of which was composed of trimer, tetramer, and pentamer, was obtained by hydrolyzing chitosan with the chitosanase originated Bacillus pumilus BN-262. High molecular weight chitooligosaccharideⅡ, 49.3% of which was composed of chitooligosaccharides over heptamer, was obtained by hydrolyzing chitosan with the cellulase originated Trichoderma viride, Aggregation property of chitosan and chitooligosaccharides was tested. Chitosan was aggregated with inorganic compounds containing divalent negative ions or organic compounds containing negatively charged polymer compounds such as proteins and nucleic acids. ChitooligosaccharideⅠ which was hydrolyzed moderately was not precipitated with inorganic compounds but was precipitated with organic compounds containing polymer compounds. ChitooligosaccharideⅡ which was hydrolyzed slightly was precipitated with inorganic compounds containing divalent negative ions or organic compounds containing negatively charged polymer compounds such as proteins and nucleic acids.

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

Historical-Dialectical Understanding of Christian Eschatology in Modern Theology

( Kuk Heon Lee ) 삼육대학교 선교와사회문제연구소 2022 Asia-Africa Journal of Mission and Ministry(AAMM) Vol.25 No.-

Since the ultimate aim of Christianity is the second coming of Jesus and the arrival of the Kingdom of God, the delaying issue of the second coming of Jesus is one of the most important issues to be solved by Christian theology. Modern theologians have made a theoretical effort to solve the problem of the delay of Jesus’ second coming. Theologians of the Liberal Theology (19’s), which emerged as an antithesis for Orthodox Theology, tried to solve this problem by culturalizating the Christian eschatology. However, they removed the objective characteristic of Christian eschatology by limiting Christ's second coming and the Kingdom of God to its intrinsic value. Emerging as an antithesis against the liberal theology, Neo-orthodox Theology transcended the Kingdom of God. But they also lost the objectivity of Jesus’ Second Coming and hope for the Kingdom of God by the Christian eschatology as it is. Such Theologians of Hope as Moltmann appeared in the middle of the 20th century, and they sought synthesis in the area of the Christian eschatology. The Theology of Hope has completely futurized the Christian eschatology. By emphasizing the future nature of the Kingdom of God, the historicity of Christian eschatology was challenged. In this study, I analyzed the understanding of Christian eschatology in modern theology with a historical dialectic method, and proposed the historical understanding of the Kingdom of God as a synthesis of Christian eschatology. That is, to understand Christian eschatology as the correct Christian theology, we should pursue the historical understanding that the Kingdom of God was presented in the past as the Crucifixion of Christ, and is realized today in the lives of Christians, and will be completed in the future through the Second Coming of Jesus Christ.

Discussion on Women`s Ordination in the History of Korean Protestant Churches

( Kuk Heon Lee ),( Han Bong John ) 삼육대학교 선교와사회문제연구소 2014 Asia-Africa Journal of Mission and Ministry(AAMM) Vol.9 No.-

This paper considers the discussion on women`s ordination in the Korean Protestant Churches. Because of the cultural situation, most Korean Protestant denominations have struggled with this issue for a long time. Nowadays, some denominations, such as the Korean Methodist Church, the Presbyterian Church of the Republic of Korea, the Presbyterian Church of Korea, the Korea Assemblies of God, the Pentecostal Church, Jesus Korea Holiness Church, and Korea Evangelical Holiness Church, have decided to allow women to be ordained ministers. Nevertheless, the other denominations, such as the General Assembly of Presbyterian Church in Korea, the Korea Baptist Convention, and Seventh-day Adventists, are still discussing this issue seriously. In history, there are some issues in this discussion. Women`s ordination has been related to biblical, cultural and social factors in Korean protestant churches. With the changing situation, expansion in women`s involvement in actual ministry is urgent. From the missionary point of view, in particular, this issue is very important and a primary task of Christian

A Study of the Biblical Infallibility in Contemporary Theology

( Kuk Heon Lee ) 글로벌기독교세계관학회 2011 학문과기독교세계관 Vol.3 No.-

Inerrancy or infallibility is one of the most important topics on Bible authority in the twentieth century. With the beginning of the fundamental movement in 1910 it became a major issue. The nineteenth century had been an era of the historical-critical method. Liberalists used the same methods as literary criticism to criticize the Bibl. The theory of infallibility of the Scriptures emerged in Christian theology in order to cope with the context. There are critical hypotheses which do charge the Bible with historical, moral, and theological deceptions. In this paper we will study the issues involved in defending biblical inspiration; and the ways contemporary theologians have dealt with these inspiration issues. Evangelicals have developed responses to historical blunders and errors in the sources, and to the moral blemishes and scientific mistakes in the Bible. Through these answers, we can understand the biblical basis of infallibility. A doctrine of infallibility leads to the issue of verbal inspiration. This becomes a rallying point for Christian fundamentalism. Infallibility of revelation is a strong position to support the authority of the Bible. The infallibility of inspiration and revelation is a core doctrine of reformed Protestantism.
