최일수 문학비평 연구 : 1950년대 비평담론의 장을 중심으로

정학재 한국언어문화학회 ( 구 한양어문학회 ) 2002 한국언어문화 Vol.22 No.-

Chung Hak jae. 2002. A study on Choi il-soo's literary criticism. The purpose o this paper is to clarify that Choi Il-Soo's criticisms sere the search for the literature of the Korean nation. The research method in this paper is Pierre Bourdieu's fields and symbolic struggles. I classified Choi's criticisms into three aspects ; (1) aspect of the literary generation (2) aspect of the attitude to the culture tradition (3) aspect of the attitude to the national literature. (1) About the literary generation, Choi used discourse strategy of inclusion and difference, distinct from other critics' strategy of exclusion and enhancement (2) About the culture tradition, Choi surpassed the strategy of concealment by the tradition negationists and abstract and ideal discourse by the tradition accessionist. His discourse included form and substance. (3) About the national literature, Chung Tae-Yong and Choi's discourses are superior to others. Because they re-defined the nationality through the historical view. (4) Choi's discourses about the national literature were continued to the concern about the third world's literature. (5) Choi's discourses about the national realism were on the basis of the confidence in the progress of history and he had the intenion to the methods of creation. finally, we could understand tat Choi's literary criticisms were superior to others'in the field of 1950's literary criticism about the aspect in the tradition and national literature and it could be more clear when compared with other critical subjects.

김종오,노권재,윤여헌,고영도,유재두,정준모,방한천,정재학 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목 적: 노령의 대퇴 전자간 골절에서 압박고 나사못의 안정성에 영향을 주는 인자들간의 상관 관계와 골절 양상에 따른 술후 고관절 기능을 평가 및 분석하였다. 대상 및 방법: 압박고 나사를 이용하여 수술적 치료를 시행한 231명의 환자 중 6개월 이상 추시가 가능하였던 60세 이상 84명의 환자들을 대상으로 했다. 방사선적 계측은 압박고 나사못의 활강 길이 및 내반각, 가압 나사 위치, 정복 상태, 원위 골편의 내측 전위를 측정하였으며 술후 기능은 Clawson의 기능 평가표로 하였고 골절 양상에 따라 방사선 계측과 기능 회복과의 상관 관계를 평가하였다. 결 과: 임상 결과는 불안정 골절에서 양호가 10례, 불량이 23례, 안정 골절에서는 양호 40례, 불량이 11례로 안정 골절에서 임상 결과가 좋았고(p<0.001), 압박고 나사 활강은 10 ㎜ 이상일 때 양호가 4례, 불량이 21례, 10 ㎜ 이하에서 양호가 46례, 불량이 13례로 10 ㎜ 이상 활강시에 술후 결과가 불량했다(p<0.001). 다르 방사선적 계측 요인은 결과에 의미있는 차이를 보이지 않았다. 또한, 불안정 골절 중에서 전위 양상 골절의 경우 10㎜ 이상 활강이 12례, 10㎜ 이하 활강이 8례, 분쇄 양상 골절의 경우는 10㎜ 이상이 11례, 10㎜ 이하가 2례로 분쇄 양상의 불안정 골절에서 10㎜ 이상 활강이 의미있게 많았다 (p<0.001). 결 론: 10㎜ 이상의 지연 나사 활강은 고관절 기능 회복 약화를 유발시킬 수 있으며 불안정 골절 분쇄 양상 골절은 이런 지연 나사의 활강이 과도하게 유발될 수 있으므로 불안정 분쇄 양상 골절에서 압박고 나사의 단독 사용은 재고해 보아야 할 것이다. Purpose: To evaluate the relationship between fracture stability and functional results, and analyze the correlation between stability factors and the outcome in intertrochanteric fracture of the elderly. Materials and Methods: Of the 231 patients, 84 patients with age above 60 were able to follow up for minimum 6 months. We measured the sliding length of the lag screw, varus degree, position of lag screw, reduction status and medialization of distal fragment radiologically. The functional outcome of the treatment was evaluated with the Clawson's result classification and we evaluated the correlation between the radiological results of measurement and the functional recovery depending on the Evans fracture classification. Results: There were good results in 40 cases out of 51 stable fractures, and in 10 cases out of 33 unstable fractures (p<0.001). In case of sliding of lag screw more than 10㎜, good results were obtained in 4 cases, and poor in 21. And in case of sliding less than 10㎜, good results were obtained in 46, and poor in 13. (p<0.001).But there was no relationship between other radiologic factors and clinical results. In unstable type, there were 12 cases with lag screw sliding more than 10㎜ and 10 cases with less than 10㎜. In comminuted type, there were 11 cases with lag screw sliding more than 10㎜ and 2 cases with less than 10㎜(p<0.001). Conclusion: The sliding of lag screw more than 10㎜ may result in poor outcome. As in comminuted unstable pattern, sliding of lag screw might be excessive, the use of compression hip screw alone is not good treatment option.

愼學宰 木浦海洋大學校 1995 論文集 Vol.3 No.1

Generally speaking, the characteristics with heavy fuel operation is different from that with marine diesel oil in diesel engines and the fuel viscosity exerts a great influence on the injection characteristics. In order to design the injection system suitably, the influence of the fuel viscosity on the injection characteristics should be understood. In response, a series of experiments and simulation calculations have been carried out. As a result, it is obtained that the decrease of leakage from plunger clearance and the decrease of flow coefficient at nozzle hole excert on influence on the injection characteristics at incleasing fuel viscosity. Moreover, it could be said that the optimum viscosity at the inlet of injection pump is less than 15∼20 cSt in the range of conventional injection system.

임재학 大田産業大學校 1997 論文集 Vol.5 No.-

In this Paper, we consider four redundant systems consisting of 2n identical components. We assume that the life times of all components are independently and exponentially distributed with the failure rate λ. Under these assumptions, we calculate the failure rate of each system in analytic way and obtain the ordering relationship between their failure rates.

잎담배 生産과 栽培環境과의 關係에 關한 解析的硏究 : 第13報. 環境要因 및 栽培方法이 잎의 形質에 미치는 影響(1) Part XIII. Effects of Some Environmental and Agronomic Factors on the Leaf Characteristics of Tobacco Plants

This experiment was conducted to study the effects of soil moisture, light condition, shading time, fertilization levels, topping time and depth and their interactions on the tobacco growth and characteristics of leaf. The results are abstracted as follows. Stem height, length and width of the largest leaf, ratio of leaf width to length, average leaf area, LAI, weight of a leaf and leaf weight of a plant decreased with insufficient soil moisture at early and middle stage of maximum growth, but thickness of leaf increased. Weight of a leaf and leaf weight of a plant decreased by shading. Stem height, length and area of the middle leaf, fresh weight and percentage of dry matter of unit leaf area and weight of a leaf were larger in the plot of shading for 20 days before topping than in that after topping, while the leaf thickness and midrib proportion of the middle leaf were just the opposite. In the case of low topping, stem height and number of harvested leaves decreased, while the percentage of dryed-up leaves, middle, upper and average leaf length, and weight of a leaf increased. But leaf weight per a plant showed little difference according to the topping depth. Length, width and area of the middle leaf, fresh weight per unit leaf area of the lower leaf, weight of a leaf and leaf, weight per a plant increased, and midrib proportion of the middle leaf decreased by early topping (50 days after transplanting). Length, width and area of a leaf increased by increased fertilization level. Consequently, weight of a leaf and leaf weight per a plant increased. Among the environmental factors treated in this experiment, the effect of soil moisture condition was more remarkable than those of light condition and shading time. And among agrononic factors, the effect of the fertilization level on the charateristics of leaf was most remarkable, that of topping depth the next, and that of topping time the least. Muddle leaves was influenced sensitively by the environmental. agronomic factors and their interaction.

국내 화물자동차운송업의 경쟁우위 결정요인에 관한 실증적 연구

이재학,송영태 한국물류학회 2005 물류학회지 Vol.15 No.1

화물자동차운송업은 국민경제에서 매우 중요한 역할을 담당하고 있는 산업으로 지난 30여년간 고용창출 및 수출증진에 많은 기여를 하여 왔다. 그러나 화물자동차운송업은 최근 유가상승, 급격한 인건비의 상승과 인력부족의 심화, 과당경쟁 등으로 심각한 경영난을 겪고 있다. 이러한 급속히 변모한 기업경영 환경속에서 화물자동차운송업은 생존을 위한 현실적 방안을 모색하지 않으면 안되게 되었다. 이에 본 논문은 물류산업의 중요한 역할을 수행하는 화물자동차운송업의 경쟁우위 요인을 파악하고, 이에 대한 분석을 토대로 화물자동차운송업의 나아갈 방향을 제시하고자 노력하였다. 본 연구를 통한 국내 화물자동차운송업의 시사점은 단순한 화물운송의 수준에서 벗어나 원스탑 물류서비스를 화주에게 제공할 수 있는 물류전문기업으로 발전해 나가야 할 것이다. 이를 위해 전문인력을 양성하고 부가서비스확대 및 강화를 위해 업계는 최선을 다해야 할 것이다. 한편, 정부차에서는 화물자동차운송업의 육성 및 발전을 위해 사회간접시설의 학충과 화물자동차운송업 관련법과 제도적 장치의 보완을 통해 보다 효율적으로 화물자동차운송업체가 기업을 운영할 수 있도록 환경조성을 위한 지원을 아끼지 말아야 할 것이다. The freight transport business has performed important role in the economic development of Korea, based on effect of big employment making and export increasing. But now the freight transport business experience hardships by a rapid rise of oil price and labor costs, manpower problems, overheated competitions between the companies etc. The freight transport business cannot find any other choice but to seek any realistic formula to win survival on such urgently changeable environment of business. Therefore this paper tries to figure out the determinate factors of competitive superiority in freight transport business that carry out an important part in logistics industry, and based on such analysis, to suggests the future pathway for freight transport business, And the suggestions for the freight transport companies through this paper are that such companies should not settle down with simple transport service, but they must turn themselves into more sophisticated professional logistics companies, which can provide one-stop logistics service to goods holders. To do so, they should trans experts and do therir best to expand and strengthen additional service. Besides, the government needs to continue to support to set up the product and the freight transport company-friendly environment by amplifying social overhead infrastructures and revising regulations and systems related to the freight transport business so that they can manage themselves more efficiently.
