矯正組織管理의 效果性에 관한 比較硏究

이영근 한국교정학회 2002 矯正硏究 Vol.- No.17

This study attempts to find ways to develop more effective correctional management in Korea, by comparing crime situation, prison conditions, and the structure of correctional agencies among four different countries, the U.S., China, Japan and Germany. Based on the notion that the primary goal of the correctional institution is to prevent criminals from committing further crimes, the foremost important job of the correctional management lies in developing more efficient operation of in-prison treatment programs. According to this understanding, this article examines the aspects of correctional education, work programs within facilities and the reward-punishment system, healthcare, devices for protecting inmates' human rights in Korea and compares them with those of four other counties. And then the study derives some weak points that the Korean correctional organizations faces and suggests how to improve the current situation.

참기름 특유향기성분의 유래에 관한 연구

이영근 密陽産業大學校 農業技術開發硏究所 1999 農業技術開發硏究所報 Vol.3 No.1

참기름의 특유향기성분의 유래를 찾고자 참깨의 특유성분인 sesamol을 가열하고 여기에서 생성하는 휘발성화합물을 Tenax trap으로 포집한 후 GC-MS로 분석한 결과 16화합물들로 분리 되었으며, 이들중 1,2-dimethyl bezene, ethyl benzwne 및 methoxy methyl acetate의 3종이 참기름의 향기성분과 동일한 화합물로 확인 되었다. 특히 methoxy methyl acetate는 참기름 특유의 향기성분으로 추정되는 화합물이어서 참기름 특유의 향기 성분이 sesamol, sesamin, sesamolin 등의 가열시 형성 되는 것으로 추정할수 있었다. Sesamol was roasted at 300℃ and its volatile compounds were absorbed in Tenax trap. The ether extact of Tenax tarp was analyzed by GC-MS for identification of the formation of sesame oil odor from sesamol. The 16 compounds were isolated from the volatile compounds of roasted sesamol, among these, 1,2-dimethyl benzene and ethyl benzene were identified as same compounds as in sesame oil odor. Furthermore, methoxy methyl acetate, presumed as the native odor of sesame oil, was also produced from the roasted sesamol.

돼지여포의 퇴화과정 중 여포액 내 스테로이드 호르몬 양의 변화

이영근,윤용달,Lee, Young-Keun,Yoon, Yong-Dal 대한생식의학회 1985 Clinical and Experimental Reproductive Medicine Vol.12 No.1

In order to study the mechanism of follicular atresia, the follicles of the porcine ovary were isolated according to the presence or absence of the corpus luteum and their size, and then classified to the normal? or atretic?follicle on the morphological observation such as the transparency, the vascularization of follicle, the nuclear phase of oocyte, and the homogeneity of the granulosa cell layer. The viability of granulosa cells was examined. The concentrations of progesterone ($P_4$), testosterone (T), and estradiol-17 beta ($E_2$) in each follicular fluid were estimated by the radioimmunoassay. The viability of granulosa cells in the atretic follicle was much lower than that of the normal one. The concentration of each steroid hormone increased as the follicular size was increased, was not different in quantity between the normal- and the atretic follicle of which diameter was below 3mm, and were much higher in the atretic follicle than those in the normal one of which diameter was above 7mm. The ratio of the concentration of E2 to T in the large atretic follicle valued higher than that in the normal one, but smaller in the small and medium atretic follicle than that in the normal one. The present study suggests that the mechanism of atresia of the large follicle may be different from that of the small and the medium follicle and that the amount of steroid hormones regarded as the one of the criteria for the atretic follicles.

遠心噴霧法으로 製造한 Al系 合金粉末 壓出材의 加工性에 미치는 溫度의 影響

李榮根 忠州大學校 1998 한국교통대학교 논문집 Vol.33 No.1

Hyper-eutectic Al-Si alloy powders are considered for high strength and abrasive resistance application, and have been produced by centrifugal atomization process, a sort of rapid solidification processes, in order to prevent coarse Si primary crystal formation which usually causes poor workability and formability, and consolidated by hot extrusion. Finely distributed Si primary crystals, which are far smaller than those in conventional casting materials, have been observed in the as-extruded bar stock. Extruded specimens were subsequently tested in compression and tensile modes at various deformation rates in the temperature range from room temperature to 500℃, in order to investigate the effect of temperature on the deformation resistance and the fracture deformation. Deformation conditions are also investigated to optimize the workability limit with a minimum working pressure in this study.

온천수로부터 분리한 항진균세균의 특성 및 감마선$(Co^{60})$ 조사를 이용한 돌연변이체 유기

이영근,김재성,송인근,정혜영,장화형 한국미생물학회 2001 미생물학회지 Vol.37 No.4

다양한 식물병원성 진균을 방제하기 위하여 온천수로부터 1종의 동물병원성 진균과 12종의 식물병원성 진균에 항진균 활성을 갖는 고온성 세균을 분리하였으며 Bacillus subtilis YS1으로 동정되었다. 분리 균주의 감마선($Co^{60}$)에 대한 감수성 조사 결과, $D_{10}$ value는 2.08 kGy로 20 kGy 의 방사선량에서도 생존 가능한 방사선 저항성 균주였다. 방사선 조사를 이용하여 5종의 돌연변이체를 유기하였으며, 이 중 B. subtilis YS1-1009 돌연변이체는 Botryoshaeria dothidea에 대한 항진균 활성의 증가 및 4종의 식물병원성 진균에 대하여 항진균 활성이 감소하는 종특이적 항진균 활성 변화를 나타내었다. 또한 상용농약인 tebuconazole에 대하여 저항성을 나타내었으며 17종의 다른 농약에 대해서도 전체적으로 야생형 균주에 비해 저항성이 증가하였다. B. subtilis YS1-1006 돌연변이체는 copper hydroxide에 저항성을 나타내었으며, B. subtilis YS67 돌연변이체는 항진균 활성이 소실된 tryptophan 및 proline 또는 uracil 및 arginine 영양요구성 돌연변이체였다. 이러한 결과로부터 극한 환경에서 분리한 본 분리균주는 환경친화적으로 진균에 의한 식물병을 방제할 수 있으며 방사선을 이용한 돌연변이체 유기는 기능성 균주의 개량이나 작용기작 연구를 위한 돌연변이체의 획득에 매우 효과적인 방법이라 사료된다. Antifungal bacterium, Bacillus subtilis YS1 was isolated from Yusong hot spring showed broad antifungal spectrum against 12 kinds of plant pathogenic fungi and Candida albicans, animal pathogen. From the gamma($Co^{60}$) radiation sensitivity test, $D_10$ value was 2.08 kGy and it survived above 20 kGy of radiation dose. Several mutants were induced by gamma radiation. Among them, YS1-1009 mutant showed resistance against tebuconazole of herbicide, increased activity against Botryoshaeria dothidea and ligninase activity. YS67 mutant was antifungal deficient auxotrophic mutants(trp-pro-or arg-ura-). From this results, it suggested that gamma irradiation could be useful method for mutant induction.

1962년 이후 한국의 식물세균병학 연구동향

이영근 安東大學校 農業科學技術硏究所 1994 農業科學技術 硏究論文集 Vol.1 No.-

1962년부터 1994년까지 한국에서 발표된 식물세균병 연구결과를 정리하였다. 모두 약 140편의 논문이 발표되었으며, 그 중 대부분이 1970년 이후에 발표된 것이었다. 이 기간 중에 23종의 식물에 발생하는 30종의 세균병이 한국에서 처음 보고되었다. 1980년대 중반까지는 벼횐잎마름병(Xanthomonas oryzae pv. oryzae)을 대상으로한 논문이 많았고, 그 후 다른 작물의 병해를 다룬 논문이 증가되는 경향이었다. 한국의 식물세균병학 연구는 아직 소수의 학자에 의해서 주도되고 있으며, 특히 이러한 경향은 병원세균 동정, 생물적 방제, 빙핵세균, 마이코프라스마유사체에 의한 병에 관한 분야에서 두드러졌다. 1990년 이후 분자생물학이나 유전공학적 기법을 이용한 접근이 많이 시도되고 있다. 한국 식물 세균병학계는 학자의 수, 발표된 논문편수에서 빠른 속도로 양적 성장을 하여 왔다. 이러한 양적 성장은 앞으로 더욱 빨라질 것으로 생각된다. The studies on plant bacterial diseases in Korea from 1962 to 1994 were reviewed. During this period, over one hundred forty papers have been published and most of them after 1970. Thirty kinds of new bacterial diseases originally reported from twenty three kinds of host plants in Korea. Many research works had been done on the rice bacterial blight Xanthomonas oryzae pv. oryzae) until about middle 1980s, but thereafter the studies on the other diseases increased. Plant bacterial pathology in Korea have been conducted by a relatively small number of researchers, particularly on the identification of pathogenic bacteria, on the biological control tactics, on the characterization of ice nucleation bacteria, and on the diseases by mycoplasma-like organisms. Since 1990, the approaches using molecular biology and genetic engineering techniques have been reported, and numbers of the researchers and papers have increased rapidly, This suggests that the scientific growth in this field be accelerated more rapidly than that of past thirty years.
