Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

국가장기생태사업(LTER)의 일환으로 한라산 아고산대 구상나무림의 물질생산과 탄소분포의 특성을 밝히고자 2009년부터 2013년까지 현존량, 유기탄소분포, 낙엽생산, 임상낙엽량과 토양 유기탄소 축척량을 조사하였다. 식물현존량은 상대생장법에 의해 보고된 물질생산 식을 이용하여 측정하고 이를 이산화탄소의 고정량으로 환산하였다. 2009, 2010, 2011, 2012 와 2013년의 현존량은 각각 98.88, 106.42, 107.67, 108.31 와 91.48 ton ha-1 였다. 이 기간 동안의 유기탄소는 지상부 생물량에 35.95, 38.69, 38.96, 39.46, 33.2 ton C ha-1, 지하부 생물량에 8.54, 9.2, 9.49, 9.28, 7.97 ton C ha-1 이 각각 분포하였다. 5년 동안 낙엽 생산을 통해 1.09, 1.80, 1.32, 2.46 와 1.20 ton C ha-1 의 유기탄소가 생태계로 유입되었다. 2010, 2011, 2012와 2013년의 임상낙엽층의 유기탄소량은 2.74, 2.43, 2.00 와 1.16 ton Cha-1였고, 토양 20cm깊이까지의 유기탄소 축적량은 55.77, 54.90, 50.69, 44.42 와 41.87 ton C ha-120cm-1였다. 이와 같이 현존량과 유기탄소량이 2009~2012년까지 매년 증가하였지만 태풍이 있었던 2013년에는 감소하였다. 이러한 현상은 자연적 교란이 한국의 아고산대 생태계에 크게 영향을 미친다는 것을 의미한다. Annual biomass production and amount of organic carbon in Abies koreana forest at Mt. Halla were conducted as a part of Korea National Long-Term Ecological Research (KNLTER). We measured standing biomass change of litter, soil production and organic carbon amounts of the forest floor and soil layer of A. koreana forest in Mt. Halla from 2009 to 2013 in permanent plots. Standing biomass, which was determined by allometric method, was converted into CO2. The standing biomass in A. koreana forest was 98.88, 106.42, 107.67, 108.31, 91.48 ton ha-1 in 2009, 2010, 2011, 2012 and 2013 year, respectively. The amount of annual carbon allocated to above ground was 35.95, 38.69, 38.96, 39.46, 33.2 ton C ha-1 and below ground biomass was 8.54, 9.2, 9.49, 9.28, 7.97 ton C ha-1 in 2009, 2010, 2011, 2012 and 2013 year, respectively. Amount of organic carbon returned to the forest via litterfall was 1.09, 1.80, 1.32, 2.46 and 1.20 ton C ha-1 in 2009, 2010, 2011, 2012 and 2013. Amount of organic carbon in annual litter layer on forest floor was 2.74, 2.43, 2.00 and 1.16 ton C ha-1 in 2010, 2011, 2012 and 2013 year, respectively. Amount of organic carbon within 20cm soil depth was 55.77, 54.9, 50.69, 44.42 and 41.87 ton C ha-120cm-1 in 2009, 2010, 2011, 2012 and 2013 year, respectively. Then standing biomass and organic carbon distribution increased steadily until 2012. But there declined in 2013 because of the typhoon Bolaven. Thus, standing biomass and organic carbon distribution of this subalpine forest were largely affected by natural disturbance factor.

목적: 만성 바이러스간질환에서 병의 경과와 예후를 평가하고 치료반응을 예측함에 있어 간섬유화의 진단은 중요하다. 최근 간섬유화 평가에 표준방법이지만 침습적 간생검을 대신하여 여러 가지 비침습적 진단법이 이용되고 있고, 또한 새로운 검사법들이 개발되고 있다. 저자들은 만성 B형 및 C형간염 환자를 대상으로 임상에서 광범위하게 흔히 시행하는 혈액검사와 임상 소견을 이용한 아래와 같은 진단법들만으로 간섬유화를 얼마나 정확하게 평가할 수 있는지 알아보고, 단일 검사로 간섬유화를 평가하는 데 유용하다고 알려져 있는 hyaluronic acid(HA)와 IV형 콜라겐 농도와 비교하여 그 임상적 유용성을 평가하였다. 대상과 방법: 2002년 3월부터 2007년 2월까지 만성 바이러스간 질환으로 간생검을 시행받은 225명의 환자(HBV 180명, HCV 43명, HBV+HCV 2명)를 대상으로 분석하였다. 간생검을 시행하는 날에 말초혈액검사, 혈액응고검사, 혈청생화학검사를 시행하고, 혈중 HA, IV형 콜라겐 농도를 측정하였다. 간섬유화의 정도는 F0(섬유화가 없음), F1(문맥역 섬유화), F2(문맥주변부 섬유화), F3(섬유성 격막) 및 F4(간경변증)의 4단계로 구분하였다. 대상 환자를 F0-1, F2-4 혹은 F0-2, F3-4의 두 집단으로 분류하여 두 집단을 구분하고자 할 때 AAR(AST/ALT ratio), API(age-platelet index), APRI(AST to platelet index), CDS(cirrhosis discriminant score), platelet count, HA, IV형 콜라겐의 예측능을 area under the receiver operating characteristic curve (AUROC)값을 이용하여 비교하였다. 결과: 대상환자의 섬유화의 단계는 F0 집단은 17명, F1 집단은 40명, F2 집단은 61명, F3 집단은 74명, F4 집단은 33명이었다. 의미 있는 간섬유화를 F2 이상으로 판단할 때, 의미 있는 섬유화의 예측에 대한 AUROC 값은 APRI=0.822, CDS=0.776, platelet count=0.773, API=0.756, HA=0.749, IV형 콜라겐=0.718, AAR=0.642 순이었고, F3 이상의 광범위한 섬유화 예측에 대한 AUROC값은 CDS=0.835, platelet count=0.795, API=0.794, HA=0.766, AAR=0.711, IV형 콜라겐=0.697, APRI=0.691 순으로 관찰되었다. 결론: 만성 바이러스간질환에서 간섬유화를 평가하는 데 임상 소견 및 혈액검사를 이용한 방법들이 비침습적 진단법 중 단독 검사로도 유용한 것으로 알려져 있는 혈중 HA와 IV형 콜라겐 농도와 비교하여 우월하거나 대등하였다. 특히 APRI는 다른 인자들에 비해 F2 이상의 의미 있는 섬유화를 예측하는 데 가장 유용하였고, CDS는 F3 이상의 광범위한 섬유화를 예측하는 데 가장 유용하였다. Background/Aims: The aim of this study was to determine the clinical performances of noninvasive serum markers for the prediction of liver fibrosis in chronic viral liver diseases. Methods: We analyzed a total of 225 patients with chronic viral liver diseases (180 with hepatitis B virus, 43 with hepatitis C virus, and 2 with hepatitis B+C virus) who underwent a liver biopsy procedure at the Hanyang University Guri Hospital between March 2002 and February 2007. Serum was also obtained at the time of liver biopsy. Liver fibrosis was staged according to the scoring system proposed by the Korean Study Group for the Pathology of Digestive Diseases. Various noninvasive serum markers were evaluated, including the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR), age-platelet (AP) index, AST/platelet ratio index (APRI), cirrhosis discriminant score (CDS), platelet count, hyaluronic acid (HA), and type IV collagen. Results: There were 17, 40, 61, 74, and 33 patients at stages F0, F1, F2, F3, and F4, respectively. The overall diagnostic accuracies of each marker, as determined by the area under receiver operating characteristics curves, were APRI=0.822, CDS=0.776, platelet count=0.773, AP index=0.756, HA=0.749, type IV collagen=0.718, and AAR=0.642 for predicting significant fibrosis (≥F2); and CDS=0.835, platelet count=0.795, AP index=0.794, HA=0.766, AAR=0.711, type IV collagen=0.697, and APRI=0.691 for predicting extensive fibrosis (≥F3). Conclusions: Conclusions: All noninvasive serum markers evaluated in this study were useful for predicting significant or extensive liver fibrosis in chronic viral liver diseases. In particular, APRI was most useful for the prediction of significant fibrosis, and CDS was most useful for the prediction of extensive fibrosis. (Korean J Hepatol 2009;15:454-463)

This experiment was carried out to evaluate the agronomic stability of North Korean rice varieties using the statistical model developed by Grafius, Finlay, and Ever hart. The lowest yearly variation based on coefficients of variation was found in Hannam 29 for number of panicles per hill, in Sijoong 9 for number of grains per panicle, in Pyeongyang 3 for ripened grain ratio, in Sijoong 16 for 1,000 grain weight, and in Yeomju 1 for grain yield. By Grafius's model, Pyeongbook 3, Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups show stable for 3 years. Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups were found to be highly stable as analyzed by both Finlay and Wilkinson's model and Everhart & Russell's model. With reference to three models, Weonsan 66 was highly stable for 3 years with showing more yield than Odaebyeo in early maturing groups while Seohaechalbyeo was highly stable for 3 years with showing high yield than Hwaseongbyeo in medium maturing groups above 5~;t~;ha-1 of milled rice respectively.

Woo Tae Ha1,Hyun Jung Park,Won-Young Lee,Ha Yeon Jeong,Hyuk Song 한국동물생명공학회(구 한국동물번식학회) 2017 Reproductive & Developmental Biology(Supplement) Vol.41 No.2

With the global demand for dairy protein for consumption growing annually, there has been increasing activity in the research field of dairy protein synthesis and production. From a manipulation perspective, it is more difficult to use live cattle for laboratory studies on the production of milk as well as of dairy protein such as casein, as compared with using laboratory animals like rodents. Therefore, we aimed to develop a mouse model of bovine mammary alveolar ducts for laboratory-scale studies. We studied the formation of the bovine mammary gland ductal structure by transplanting the MAC-T bovine alveolar cell line into mice. MAC-T cells (1×107) were suspended in Matrigel and injected into the dorsal tissue of 8-week-old male BALB/C nude mice. Histological analysis of tissue dissected from the MAC-T cell-transplanted mice after 6 weeks showed the typical morphology of the tubuloalveolar female gland, as well as glands made up of branching ducts that were surrounded by smooth muscle with small alveoli budding off the ducts. In addition, the epithelial markers CK14 and CK18 were expressed within the duct-like structure. Prolactin was detected in the duct interior in these CK14+ and CK18+ cells but not in the non-transplanted MAC-T cells. These results showed that duct-like tissue had been successfully formed after 6 weeks of transplantation of the CK14+ and CK18+ MAC-T cells into mice dorsal tissue. This mouse model will be a useful tool for further research on the bovine mammary gland.

변호사시험 문제 문장론 비판 -2020년 제9회 형사법 선택형·사례형-

하태영 ( Ha Tae Young ) 한국비교형사법학회 2021 비교형사법연구 Vol.22 No.4

내부 문제를 논문으로 쓴다니 고통이다. 그러나 외부에서 지적하기 전에 내부에서 정리가 되었으면 한다. 그래서 많은 비판을 감수하고 몇 가지 지적을 하려고 한다. 변호사시험 문제는 단서가 있다. ‘다툼이 있는 경우 판례에 따름’이다. 논란을 줄이기 위한 방편이다. 그러다 보니 ‘판례 문장’을 그대로 옮겨 오는 경우가 대부분이다. 이해는 가지만, 문장이 너무 길다. 「∼고, ∼데, ∼만, ∼서, ∼로, ∼면, ∼하는바, ∼경우」 등 여러 접속사를 줄여 붙여 쓴다. 그래서 주어와 목적어(목적절) 그리고 동사가 문장 어순에서 상당히 분리되어 있다. 전문가들만 아는 문체가 되어 버렸다. 여기에 익숙하다 보면, 문장도 이런 문장이 법문장으로 고정되어 버린다. 무의식과 의식으로 법률가 머리에 고착된다. 당연하다고 생각한다. 그러나 이것은 아니다. 이제 무엇이 문제인지 하나씩 살펴보려고 한다. 문제은행 출제위원과 변호사시험 출제위원이 의식을 가지고, 고쳐 가면, 바꿀 수 있다. 여기에 하나의 기준점을 제안하려고 한다. 국어학자도 변호사시험출제 현장에 있지만, 출제자의 의도에 따를 수밖에 없는 구조다. 작은 변화가 판결 문체를 바꾸고, 예비 법조인 문체를 바꿀 수 있다면, 이 논문이 소망하는 의도는 완성된 것이다. 먼저 2020년 제9회 변호사시험 선택형과 사례형 문장을 살펴보고자 한다(II). 논문 분량 때문에 전부 소개할 수 없다. 그래서 임의로 20개 문장만 선정하였다. 이어서 변호사시험 문장을 분석하고자 한다(III). 다음으로 2020년에 시행된 변호사시험 문제와 의사 국가고시 시험문제와 비교하여 문장의 문제점을 선명하게 부각하고자 한다(IV). 결론에서 대한민국 변호사시험 문제가 가야 할 문체 정비를 강조하고자 한다(V). 법률가에게 주어진 덕목 중에서 가장 소중한 것이 모국어를 탁마하는 일이다. 국어를 갈고 닦아서 아름답게 꾸미는 것은 국민들의 마음을 아름답게 하는 일이다. 그런 소임은 국어학자에게만 주어진 것이 아니라, 법률가들에게 주어진 의무이자 권리이다. 독일 국가시험 사례 문제를 보면, 문장은 모두 단문이다. 나의 출제 경험이다. 몇 년 전 국가시험 출제를 다녀왔다. 형사소송법 사례 문제를 공동으로 출제했다. 나는 문장을 단문으로 다듬고, 주어와 술어를 분명하게 출제하고 싶었다. 그러나 실무가 출신 교수는 이러한 내 생각과 달랐다. 한 문장으로 물 흐르듯이 몇 개의 상황을 멋지게 엮었다. 그분은 이러한 문장에 익숙했다. 시간 촉박과 배려로 그의 생각을 전면 수용했다. 변호사시험 시험문제문체 철학이 출제위원들에게 부족했다. 이 논문이 변호사시험 문제 문체론을 성찰하는 기회가 되기를 원한다. 언론인 조지프 퓰리처(Joseph Pulitzer, 1847∼1911) 말이다. “무엇이든 짧게 써라. 그러면 읽힐 것이다. 명료하게 써라. 그러면 이해될 것이다. 그림같이 써라. 그러면 기억 속에 머물 것이다.” 시인 나태규 말이다. “제발 세종대왕을 생각하면서 문장을 쓰자. 한글 창제의 정신을 더 올리면서 문장을 쓰자. 좀 더 쉽게 쓰고, 단순하게 쓰고, 짧게 쓰자. 그러면 수험생은 문장을 즐겨 읽어 줄 것이다. 그 문장은 다시 법조인을 통해 각종 문서로 표현될 것이다.” 법률가들은 세종대왕을 늘 생각하길 바란다. 아름다운 문장을 쓰는 법률가가 점점 많아지기를 소망한다. 국민과 함께하는 법조인이다. It's painful to write an essay on internal issues. However, it is hoped that it will be cleaned up internally before being pointed out from the outside. So I'm going to risk a lot of criticism and make some points. As a result, most of them carry the "judgment sentence” as it is. I understand, but the sentence is too long. 「∼고, ∼데, ∼만, ∼서, ∼로, ∼면, ∼하는바, and, but, because, by the way, so, if, what one does, in case of, and so on, etc」. It is abbreviated and pasted with multiple accessors. Thus, subject, object (purpose clause) and verb are quite separated from sentence word order. It has become a style that only experts know. If you get used to it, the sentence is also fixed as a legal sentence. Law is stuck in the head by unconsciousness and consciousness. I take it for granted. But this is not. Now I'm going to take a look at what the problem is one by one. Question bank examiners and bar exam examiners can change it if they are conscious and correct it. I would like to propose one reference point here. Korean linguists are also present at the bar exam, but they have no choice but to follow the intentions of the test takers. If a small change can change the sentence style, and a preliminary legal style, the intention this paper desires is complete. First of all, we would like to examine the elective and case-type sentences of the 9th Bar Examination in 2020 (II). I can't introduce everything because of the volume of the thesis. Therefore, only 20 sentences were selected at random. Subsequently, an analysis of the bar exam sentences is made (III). Next, we would like to highlight the problems in sentences clearly compared to the bar exam questions and the doctor's national exam questions in 2020 (IV). In conclusion, I would like to emphasize the reform of the style of the Korean bar exam. Among the virtues given to a lawyer, the most precious is the bashing of one's native language. To polish and polish the Korean language and decorate it beautifully is to beautify the hearts of the people. Such responsibilities are not only given to Korean linguists, but also to lawyers. When you look at the question of the German national examination case, the sentences are all short. It's my experience on the test. I went to the national exam a few years ago. The case of the Criminal Procedure Act was jointly presented. I wanted to refine the sentence into short sentences, and set the subject and predicate clearly. But the professor from the working class was different from what I thought. A few situations were beautifully woven into one sentence. He was used to these sentences. He fully embraced his ideas with time and consideration. The written philosophy of the bar exam questions was insufficient for the examiners. I want this paper to be an opportunity to reflect on the written theory of the bar exam question. Joseph Pulitzer (1847-1911), a journalist. "Write anything short. Then it will be read. Write clearly. Then you'll understand. Write like a picture. Then I'll stay in my memory.” Poet Na, Tae-Kyu. "Please write a sentence thinking of King Sejong. Let's write a sentence while raising the spirit of Hangeul creation. Let's write more easily, write simply, and write short. Then the examinee will enjoy reading the sentences. The sentence will again be expressed in various documents through legal personnel.” The lawyers want to think of King Sejong all the time. I hope there will be more and more lawyers writing beautiful sentences. He is a lawyer with the people.

The Comparisional Analysis of Colostrum Protein between the First and Third Days after Calving using Proteomic Analysis

Woo Tae Ha1,Hyun Jung Park,Won-Young Lee,Ha Yeon Jeong,Hyuk Song 한국동물생명공학회(구 한국동물번식학회) 2017 Reproductive & Developmental Biology(Supplement) Vol.41 No.2

The colostrum proteins are an important energy source for newborns and improves their innate immune system. Recently, there are many interest about beneficial factors in colostrum to health and many products using colostrum are attentive into dietary supplements in global industry. The aim of this study was to compare the enriched proteins between the colostrum from the first and the third day after calving using proteomic analysis and to analyze which enriched protein will be useful to industry of dietary supplements. In this study, cows in the experimental group were fed a standard composition of feed for 12 months, after which we collected the colostrum on the first and the third day after calving. By comparison between the first and the third day colostrum, several factors, including beta-lactoglobulin, fibrinogen gamma-B chain, complement C3, zinc-alpha-2 glycoprotein, bP47 protein, beta casein, and alpha-S2 casein were enriched in the third day colostrum, whereas immunoglobulin gamma 1 and beta- casein A2 were enriched in the first day colostrum. The results suggest that the colostrum composition depends on time and the first day colostrum is important to establish the primary specific immune system, whereas the third day colostrum might regulate the non-specific immune system and increase nutrition using casein and the third day colostrum might be useful dietary products for supporting the immune system.

The soybean cultivar, ‘Saegeum’, has been developed for preparing soy-paste and tofu. The soybean cultivars ‘Daepung’ and ‘SS98207-3SSD-168’ were crossed in 2003 to obtain ‘Saegeum’. Single seed descent method was used to advance the generation from F3 to F5, and the plant lines with promising traits were selected from F6 to F7 by pedigree method. The preliminary yield (PYT) and advanced yield trials (AYT) were conducted from 2009 to 2010, and the regional yield trial (RYT) was conducted in 12 regions between 2011 and 2013. The morphological characteristics of ‘Saegeum’ were as follows: determinate plant type, white flower, tawny pubescence color, and brown pod color. Flowering and maturity dates were August 2, XXXX and October 17, XXXX, respectively. Plant height, first pod height, number of nodes, number of branches, and number of pods were 79 cm, 18 cm, 16, 2.3, and 44, respectively. The seed characteristics of ‘Saegeum’ were as follows: yellow spherical shape, yellow hilum, and the 100-seed weight was 25.4 g. ‘Saegeum’ was resistant to bacterial pustule and SMV in the field test, and its lodging resistance was mildly strong, whereas its shattering resistance was excellent. The ability of this cultivar to be processed into tofu, soybean malt, and other fermented products was comparable with that of ‘Daewonkong’. The yield of ‘Saegeum’ in the adaptable regions was 3.02 ton ha-1. Thus, ‘Saegeum’ is adaptable to mechanized harvesting because of its high first pod height, as well as lodging and shattering resistance. (Registration number: 5929)

Jang, Rae-Ha,Jeong, Heon-Mo,Lee, Eung-Pill,Cho, Kyu-Tae,You, Young-Han The Ecological Society of Korea 2017 Journal of Ecology and Environment Vol.41 No.1

Background: In order to investigate organic carbon distribution, carbon budget, and cycling of the subalpine forest, we studied biomass, organic carbon distribution, litter production, forest floor litter, accumulated soil organic carbon, and soil respiration in Taxus cuspidata forest in Halla National Park from February 2012 to November 2013. Biomass was calculated by using allometric equation and the value was converted to $CO_2$ stocks. Results: The amount of plant organic carbon was $13.60ton\;C\;ha^{-1}year^{-1}$ in 2012 and $14.29ton\;C\;ha^{-1}year^{-1}$ in 2013. And average organic carbon introduced to forest floor through litter production was $0.71ton\;C\;ha^{-1}year^{-1}$. Organic carbon distributed in forest floor litter layer was $0.73ton\;C\;ha^{-1}year^{-1}$ on average and accumulated organic carbon in soil was $51.13ton\;C\;ha^{-1}year^{-1}$ on average. In 2012, Amount of released $CO_2$ from soil to atmosphere was 10.93 ton $CO_2ha^{-1}year^{-1}$. Conclusions: The net ecosystem production based on the difference between net primary production of organic carbon and soil respiration was $-1.74ton\;C\;ha^{-1}year^{-1}$ releasing more carbon than it absorbed.
