We investigate the effect of preharvest spray of aminoethoxyvinylglycine (AVG), an inhibitor of ACC synthase activity, on fruit quality of ‘Wonhwang’ pear (Pyrus pyrifolia Nakai). And the effects were compared with ethephon which releasing ethylene to elucidate treatment efficacy of ethylene biosynthesis inhibitor on Asian pears. Chemicals were sprayed on 30 days before harvest with AVG (75 and 150 mg/L) and ethephon (100 mg/L), respectively. Highest flesh firmness during 21 days of shelf-life at 25℃ after 30 days of cold storage was attained in the fruit treated with 150 mg/L AVG (26.5N) when compared with untreated control (16.7N), while the fruits treated with 100 mg/L ethephon completely lost their marketability within 14 days of shelf-life by mass drop of firmness down to 11.6N. Low incidence of physiological disorders including pithiness and core browning were attained at the fruits treated with 150 mg/L AVG when we compared with untreated control. No occurrence of mealiness found in the fruits treated with AVG but ethephon treated fruits showed 36.4% during 14 days of shelf-life. Consequently, AVG spray at the concentration of 150mg/L on Asian pear ‘Wonhwang’ fruit regarded as useful preharvest management approach for keeping quality during marketing period after simulated exportation.

『테스』의 포스트모던적 관점 : 「순결한 여성」의 재현과 재현 불가능에 대하여 Paying attention to Representation and Misrepresentation of the Subtitle. ' A Pure Woman'

안진수 단국대학교 1998 論文集 Vol.32 No.-

The aim of this study is to answer the following questions from a postmodernist's view : Is Hardy's 'Pure woman' faithfully presented by Thomas Hardy? Does the subtitle suggest just how ironically conscious Hardy was of representation as a potent source, precisely, of misrepresentation? Had the image already substantively replaced 'the thing itself' for Hardy? Was already discrediting the notion there is an ultimate reality, or true essence, outside of history and discourse - such as human nature of pure woman? To achieve the above - mentioned aim, in chapter Ⅰ, I sought the general character of Hardy's imagination in his power of visualization. I concluded that Hardy's novels are visual novels. It is in his ability to make us see that his greatest strength lies. In Ⅱ, I reflected briefly on the general state of the last two decades of Hardy criticism from realism to postmodernism. In Ⅲ, I tried to define the meaning of 'Vision' and 'Moment', but only to find their ambiguity. In Ⅳ, I knew that Hardy's subtitle. "A Pure Woman" could only be presented as visualizations, only as she appeared, but that the basic realities of her existence were unknowable, unrepresentable. Conclusively, in chapter Ⅴ, I certified the absence of 'A pure woman', Hardy's novel, then, well ahead of its time, seems to be dismantling the bourgeois - humanist notion of the unified and unitary human subject.

DNA 수준에서의 형별법 확립이 시급한 HLA-Cw

안수진,전태연,김태규,한훈 대한조혈모세포이식학회 1999 대한조혈모세포이식학회지 Vol.4 No.1

조혈모세포 이식시 HLA 대립유전자 형벌이 갖는 중요성은 주지의 사실이고, 최근에는 타인간 조혈모세포이식이 활발히 진행되고 있어 더욱 정확한 HLA 대립유전자 형벌이 요구되고 있는 실정이다. 특히 HLA-Cw 항원은 자연살해세포와 상호 작용할 뿐만 아니라, HLA -A,B 항원과 마찬가지로 항원성 펩타이드를 세포용해성 T 림프구에 제시하여 면역 반응에 관여하고, 한가지 항원만이 검출되는 비율이 약50%나 되므로, HLA-Cw 대립유전자 형별은 필수적이라 하겠다. 그러나 HLA-Cw 항원은 HLA-A,B 항원과 비교하여 10%정도가 세포 표면에 표현되므로, 동종항체 형성률이 낮아 35종류 이상의 대립유전자가 존재하여도, 8종류 (Cw1-8) 의 표현형에 대한 항체만이 사용되고 있는 실정이다. 본 연구에 의하면 한국인에 존재하나 혈청학적인 방법으로 검출할 수 없었던 대립유전자가 약 20%에 달하고, 50%이상의 출현빈도를 보이는 Cw3 대립 유전자는 서로 다른 아형을 갖고 있다. 다시 말해, 현재의 HLA-Cw 대립유전자 형별법은 위음성률이 높고 부정확하므로 면역세포인 조혈모세포의 이식성공률을 놓이기 위해서는 DNA 수준에서의 형별법이 시급히 요청된다. In hemopoietic stem cell transplantation(HPSCT), the identification of HLA allele is very important. Recently, the unrelated hemopoietic stem cell transplantation (UHPSCT) is briskly progressed, and more accurate identification of HLA allele is required. By means of conventional serology, HLA-Cw cannot be phenotyped precisely. And in approximately 50% of the case, only one HLA-Cw molecule can be determined, so the accurate identification is very indispensible in HLA-Cw alleles. Especially, HLA-Cw molecules are interacted with class I receptors expressed on natural kill cells. Like HLA-A and -B, HLA-Cw molecules can present the fragmented antigens to cytotoxic T lymphocytes, which can be participated in immune response Therefore, the typing of HLA-Cw allele is indispensable in immune response. But HLA-Cw molecules are expressed to a low molecules (10%) compared to HLA-A, -B antigens. Although over 35 types of HLA-Cw allele are present, only 8 types (Cw1-Cw8) of HLA-Cw antibody have been used because evaluated rates of alloantibody are low. In this study, with the ARMs-PCR method, we identify 18 HLA-Cw alleles and over 20% of HLA-Cw alleles have not been identified by serology in normal Koreans (n=241). The most frequent HLA-Cw allele is HLA-Cw*03 which consists of different subtypes. And among them two subtypes, Cw*0303 and Cw*0304, comprise more than 50%. In conclusion, the conventional serology method may not detect an additional allele or may determine the allele incorrectly. It is suggested that DNA-based method is an urgently required step to increase the success rate of hemopoietic stem cell transplantation.

NaOH 첨가에 따른 음식물찌꺼기 고온 혐기성 산발효

안철우,이철승,서종환,박진식,문추연,장성호,김수생 한국환경농학회 2004 한국환경농학회지 Vol.23 No.4

본 연구는 음식물찌꺼기의 혐기성 산발효에 있어 여러 조건들 중 온도가 효율적인 가수분해와 산발효에 미치는 영향을 검토하기 위해 고온(55℃)과 중온(35℃)에서 각각 실험을 수행하여 다음과 같은 결론을 얻을 수 있었다. 음식물찌꺼기의 혐기성 산발효시 산생성 효율을 높이기 위한 전처리 과정으로 음식물찌꺼기에 NaOH를 투입한 결과 가수분해효율을 표현한 가용화 정도(Solubilization)가 0.01 g NaOH/g TS이하로 투입된 경우 0.01 mgSCOD_(prod)/mgICOD_(inf)이하를 나타내었으나, 0.05 g NaOH/g TS이상을 투입했을 때는 0.07~0.09 mgSCOD_(prod)/mgICOD_(inf)로 나타났다. 따라서 음식물찌꺼기에 NaOH를 투입하여 효율적인 가수분해가 이루어지기 위해서는 g TS당 0.05 g이상의 NaOH가 투입되어야 할 것으로 판단된다. 음식물찌꺼기를 NaOH로 전처리한 후 고온(55℃) 산발효를 실시했을 때 0.05 g NaOH/g TS 투입시 SCOD의 증가치 3,800 mg/L로 최대의 가용화와 산생성에 효과적인 pH 5.95를 얻을 수 있었다. 0.05 g NaOH/g TS를 투입하여 중온(35℃)에서 산발효를 실시한 경우와 비교하여 SCOD 증가치가 약 5배 정도 높았고, 최대 가용화에 이르는 시간도 중온의 2/3 정도로 짧아 음식물찌꺼기의 가용화에는 고온이 효과적인 것으로 나타났다. NaOH 0.05 g NaOH/g TS로 전처리된 음식물찌꺼기의 산발효 결과 고온(55℃) 및 중온(35℃)에서 각각 반응시작 후 72시간에 12,600 mg/L, 120tlrksdp 9,800 mg/L의 VFA농도를 나타내어 동일기질을 이용하여 산발효를 실시했을 때 중온보다는 고온에서 미생물의 활성증대와 유기물의 가수분해가 촉진되어 VFA생성이 효율적인 것으로 판단되었다. 고온에서 NaOH에 전처리된 음식물찌꺼기를 산발효 시켰을 때 VFA가 가장 높았던 시점을 기준으로 VFA의 조성을 조사한 결과 acetic acid가 45.9%, butyric acid가 26.7%, propionic acid가 13.9% 등으로 총 유기산 발생량의 86.5%를 차지하였다. This study showed that thermophilic anaerobic acid fermentation of food wastes had an enhanced hydrolysis capability and improvement of acidification efficiency. Influence of pH on the anaerobic hydrolysis and acidogenesis was investigated to determine the proper alkalinity in the thermophilic fermentation of food wastes. The results of putting NaOH as alkali to evaluate hydrolysis and acid fermentation efficiency in acid fermentation process of food wastes showed that the food wastes pretreated with 0.05 g NaOH/g TS had the maximum 12,600 mg/L of VFAs concentration during HRT 3 days in 55℃ hermophilic condition and the maximum 9,700 mg/L of VFAs concentration during HRT 5 days in 35℃ mesophilic condition. The accomplishment of high VFAs concentration resulted from that the main component of food wastes such as cellulose, lignin and etc. is performed active chemical decomposition by alkali in thermophilic condition. The major components of VFAs produced from the thermophilic acid fermentation process of food wastes were the short chain fatty acids such as acetic acid, butyric acid, and propionic acid.

Jude the Obscure의 自然主義的 觀點 : 주로 形式, 素材, 方法面을 中心으로 Chiefly paying attention to Form, Subject Matter, Mathod

安鎭洙 단국대학교 1984 論文集 Vol.18 No.-

In this paper, I've observed the process that Thomas Hardy traces Jude's dream, frustration and conflict in terms of a naturalistic form, subject matter and method in Jude the Obscure. In every respect, Jude the Obscure meets the theoretical requirements of naturalism. As for the form, Jude's marriage-failure is thought to be due to his origin (blood, heredity) and the effects of milieu and cricumstances (unreasonable ready-made ethics, social convention), through which the desire to trace the evolution of a human being is the characteristically drawn-out form of the naturalist novel. In the subject matter, Jude the Obscure is based on the realistic description of the problems of poverty, exploiting, dirtiness which naturalists treat willingly. Hardy expresses his will to reform social institution in Jude. Accordingly he is called a meliorist. In other words, owing to the unreasonable man-made institutions, even the normal sexual drive is distorted and the cursed married life is compared to a trap in which man and wife are caught. (Chapter Ⅱ Part Fourth) Jude and Sue are trapped in a maze of unhappiness, from which there is no escape except death. Therefore, Hardy argues that we should straighten the distorted human nature by renovating the old-fashioned institutions and coventions. Realistically describing the various irrational social systems and delivering attacks against them seem to be Hardy's intention to stress on the recognition that if there is a better way, it is to see the worst. Jude the Obscure deals forcibly, often critically and sometimes bitterly, with a variety of themes: education, marriage, sex, religion, ethics, blood, modern man's hypochondria. Speaking of the method, he describes the social environment scientifically and too far minutely. The structure is stone-mason's geometry which consists of parallelism and symmetry. Marcel attributes this trait to Hardy's training and professional experience as an architect. Finally, the resume of the story is as follows: Part One is primarily an account of Jude's youth up to the moment he departs for Christminster in search of learning. Part Two (at Christminster) brings Hardy's spiritual Whittington to his London where he is taught that his desire for learning had been only "a social unrest which had no foundation in the nobler instincts; which was purely an artificial product of civilization." In Part Three Jude, having realized that learning is vain and that only his "altruistic feeling" had any "foundation in the nobler instincts," goes to Melchester. In Part Four Jude's education is almost lost sight of in the welter of narrative detail. There follows in Part Five a period when "the twain were happy―between their times of sadness―"Hardy shows them as devoted lovers at the Great Wessex Agricultural show. In Part Six, it is here at Christminster that Hardy makes the most extreme use of his one completely symbolic character, Father Time. All through Part Five he has been used to strike the ominous note which remind us that Sue and Jude's moderate happiness is a snare and a delusion. Jude the Obscure is Hardy's bleakest, most pessimistic, most depressing novel without any happy and pastoral atmosphere from the beginning to the end. On the assumption that we should renovate the various irrational social systems, Hardy is convinced that the melancholy and depressed atmosphere can be converted into a bright one.

Aluminum 合金材 Frame을 利用한 壁體거푸집工法의 實用化를 위한 工事費 分析에 관한 硏究

안재철,안진봉,정민수,강병희 동아대학교 건설기술연구소 2000 硏究報告 Vol.24 No.2

This study is to investigate economical efficiency of using ALWOOD Form compared with that of EURO Form. ALWOOD Form is improved in the capacity in the wall-concrete structure in stead of using the existing form which has problems such as, the loss of labor when it is constructed or disjointed, and it's economical efficiency compared with that of EURO Form. The price of ALWOOD Form is more expensive than that of EURO Form due to its main material, aluminum-compound metal, composing frames. In a consequence, the cost of materials per unit area is increased. However, labor cost of ALWOOD Form based on the result of mobilization of manpower in construction field is saved due to the reduction of labor in using ALWOOD Form compared with that of EURO Form. As a result, using ALWOOD Form is more economical than that of EURO Form because saving labor cost which plays a major part in cost saving in formwork is more effective in retrenching total cost than increment of material cost.

Thomas Hardy와 D. H. Lawrence의 비극관 비교 연구

안진수 단국대학교 1999 論文集 Vol.34 No.-

The aim of this study is to clarify the characteristics of the tragic vision of Thomas Hardy and D. H. lawrence through their literary world, especially some of their novels. Both Hardy and Lawrence admired tragedies. Hardy's admiration was also accompanied by what is called his pessimistic philosophy of life.He frankly believed and proclaimed that we live on a "blighted star" and that it is natural for things to go wrong, for hopes to be frustrated, for brave rebels to be defeated and for his protagonists to spend their life in an unfruitful quest of fulfilment. Hardly mostly presents drama on a smaller scale-as enacted in the lives of ordinary people, in small place and comprising the stuff of our sympathies than the tales of the great heroes of the past ages. Lawrence admired Hardy's art, but not his philosophy. Lawrence appreciated tragedies but believed that an artist's work should be a "kick at misery". But the beliefs of Lawrence the man have very little to do with Lawrence the artist. His philosophy of life as presented in his letters and dogmatic essays has very little in common with vision of life and the plight of man as presented in his works of art. His artistic experiences were similar to Hardy's. His perceptions of life was not very different from Hardy's. So, in spite of all the obvious differences, there is a fundamantal similarity in his vision of life as preaented by the two writers. To a casual reader Lawrende's works may seem to affirm optimism and to preaent a happy vision of life. but Lawrence's very dogmatic optimis shows that he protests too much. Lawrence the artist could not but see that we live in a blighted world and that there is no other world for us to escape to, but Lawrence the prophet refused to accept the authenticity of his vision and proclaimed ways of escape. But on careful analysis the ways prove to be impracticable-and Lawrence the artist was aware of this and was always in conflict with Lawrence the philosopher. Lawrence's novels owe a great debt to Hardy in their ideas, characterization, and certain subtleties of technique. Both Hardy and Lawrence dislike city life and find beauty and happiness for man in the quiet countryside. Both Hardy and Lawrence reject modern mechanized life. Hardy shows the unhappiness of men and women under the artificial system. One step more, Lawrence shows the happiness of people freedfrom the bondages of the system. Here he differs from Hardy. Unlike Hardy's, Lawrence's main concern was not the presentation of the tragic vision of life, but the search for solutions to the problems of life. But his novels give us the actual process of the search - and that in itself is full of tragic qualities. Considering the modern age, we find ourselves echoing lawrence: "Ours is essentially a tragic age".(LCL. 5)

Film dosimetry as a part of patient specific intensity modulated radiation therapy quality assurance (IMRT QA) has been accomplished to develop the new optimization method of film isocenter offset and to suggest the new quantitative criteria for film doimetry after optimization. Five patients with head and neck cancers were measured in IMRT dosimetry by film method. Optimization method with the local minimum was developed to adjust the film isocenter offset error, which is the biggest part of systemic errors. The mean ratios were 5.33% and 7.09% for 5mm and 1 mm resolution dose data optimization respectively.
