Topographic parameter play an important role in determining the nature of water resources and related hydrological modelling.Recently, the research related in analyzing topographic parameter that which are required in hydrological analysis using GIS techniques is achieved.A watershed analysis tend to use a digital elevation model from LiDAR rater than that of extracted traditional map sheet.DEM quality and resolution affect the accuracy of any extracted hydrologic topographic parameters.Therefore, it is demonstrated that a LiDAR-derived DEM with high accuracy and high resolution offers the capability of improving the quality of watershed boundary extracted from DEMs. KeyWords : LiDAR, DEM, Topographic paramenter, Watershed

孟子의 性命思想

黃義東 淸州大學校 1984 論文集 Vol.17 No.1

This paper is to make a full discussion 'Sein-Prinzip' and 'Sollen-Prinzip' of human being through Nature and Decree thoughts of Mencius which succeed to Heaven-Decree thoughts of the old Confucianism. A writer tries to comprehend what is called Nature of Mencius as 'Sein-Prinzip' of human being and to grasp Decree as 'Sollen-Prinzip' of human being. And besides, Nature as 'Sein-Prinzip' of human being again is divided into the physiological nature and the justifiable nature, therefore Life and Righteousness are regulated as 'Sein-Prinzip' of human being. Of course, it is said that the physiological nature in Mencius is not the category of nature of human being, but the Nature in Mencius include apparently the physiological nature. Therefore, Mencius understands human being as the physical, physiological being as well as the justifiable, spritual being, here is apparently a distinguished mark of the old Confucianism. The justifiable nature also is what distinguish human being , from another animals, that is, it is the possible foundation of a ethical, moral being of human being. Then, what is 'Sollen-Prinzip'? It is known through 'Sein-Prinzip' of human being, and to live by 'Sein-Prinzip' of human being becomes 'Sollen-Prinzip' of human being. Thus, 'Sollen-Prinzip' of human being in Mencius can be separated into the physiological decree (Profit) and the justifiable decree (Righteousness). The physiological decree means to go toward the pragmatic value and the justifiable decree means to do the justifiable value. Although Mencius's Decree can be interpreted as the meaning of the fate, the writer intends to interpret it as the meaning of the mission and the duty. The fate and the mission are determined by the subjective consciousness of the human being. The real character of human being and the mission are not two, but one. We discover the curious theory of the life and the justice, the soul and the body of human being through Nature and Decree thoughts of Mencius and simultaneonsly know that for human being to live rightly is also the double-worthy uniformity of the justice and the practical profit. Thus, by my subjective consciousness, I understand the meaning of Heaven and know my real character and comprehend my mission. Therefore, with understanding and Practicing my mission, the life of Nature and Decree uniformity which realized my real character entirely is possible.

김동현,박신구,김환철,이의철,김정훈,임종한 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.2

목적: 국내외를 통해 직무스트레스와 감기 등과 같은 감염질환과의 관련성에 대한 연구는 많지 않으며, 특히 국내에서의 연구는 거의 전무한 실정이다. 이에 직무스트레스와 감기와의 관련성을 확인하고자 한다. 방법: 일개 대학병원의 산업의학과에서 보건관리대행을 이행하고 있는 83개의 사업장, 근로자 6,699명에 대해 한국형직무스트레스-단축형(KOSS-SF) 설문지를 배부하였고 회수된 4,637명의 설문지 중 부적절한 응답과 다른 호흡기와 관련한 폐질환을 앓고 있는 237명을 제외한 최종분석 근로자 4,400명(65.7%)의 설문자료를 근거로 연구를 시행하였다. 결과: 감기 경험과의 단변량분석에서 유의한 차이를 보인 요인들과 일상생활 스트레스를 보정한 후 시행한 직무스트레스와 감기 경험과의 로지스틱 희귀분석 결과 직무 자율성 결여를 제외한 직무스트레스 하부 영역 전반(직무요구, 관계갈등, 직무불안정, 조직체계, 보상부적절, 직장문화)에 걸쳐 통계적으로 유의한 차이를 보여주었다. 또한 직무스트레스와 감기 경협 첫수와의 관련성을 확인하기위한 다중회귀분석에서도 비슷한 양상을 보였다. 결론: 직무자율성 결여를 제의한 한국형 직무스트레스 요인 전체가 감기와 관련성을 나타내었다. Objectives: To investigate the relationship between job stress and the common cold which is one of the most common infectious disease. Methods: A KOSS (Korean Occupational Stress Scale)-based questionnaire survey was conducted targeting 6,699 workers, of which 4,637 questionnaires were returned and the data for 237 were excluded due to poor response and having pulmonary disease other than common cold. Consequently, 4,400 (65.7%) returned questionnaires were analyzed. Multiple logistic regression analysis and multiple linear regression, adjusted for daily life stress, confounding variables and both, were used to evaluate the relationship between job stress and the common cold. Results: After adjustment for confounding variables and daily life stress, most of the subscales of job stress contributed to an increased risk of common cold. Conclusions: These results indicated that job stress may play a significant role in increasing the risk of the common cold and that further preventive efforts and studies are needed to reduce job stress and address infectious disease caused by job stress among Korean employees.

안기동,황의환,이상래 대한구강악안면방사선학회 2004 Imaging Science in Dentistry Vol.34 No.2

Purpose : To investigate the histopathological changes in the temporomandibular joint in streptozotocin-induced diabetic rat following irradiation. Materials and Methods : Sprague-Dawley rats weighing about 250 gm were divided into three groups: control, diabetic, and diabetic-irradiated groups. Diabetes mellitus was induced in the rats by injecting streptozotocin. Rats in the control group were injected with citrate buffer only. After 5 days, the head and neck region of the rats in diabetic- irradiated group were irradiated with single absorbed dose of 10 Gy. The rats were killed at 1, 3, 7, 14, 21, and 28 days after irradiation. The specimen including the temporomandibular joint were sectioned and observed using a histopathological method. Results : In the diabetic group, severe bone resorption in the mandibular condyle was observed throughout the period of experiment. Necrosis of bone marrow and trabeculae was observed at 28 days after diabetic state. Atrophy and fibrosis in the retrodiscal tissue was gradually progressed during the time of the experiment. In the diabeticirradiated group, severe bone resorption in the mandibular condyle was observed during the early experimental phases, but regeneration of bone marrow was initiated at 14 days after diabetic state and irradiation. Also, calcification of abnormal trabeculae was observed at 28 days after diabetic state and irradiation. The retrodiscal tissue was degenerated in the early experimental phases, but it had been gradually regenerated during the experimental time. Conclusion : This experiment suggests that bone resorption and degeneration in the mandibular condyle are caused by the induction of diabetes, and abnormal bone formation is induced after irradiation in diabetic state.

高峰의 經世思想

黃義東 청주대학교 인문과학연구소 1991 人文科學論集 Vol.10 No.-

Ko-Bong is in a position to interlink Yi-Hwang(李滉) and Yul-Gok(栗谷) in the Neo-Confucianism of Yi dynasty. He held a controversy with Yi-Iiwang, and contributed greatly to the development of the Neo-Confucianism of Yi-dynasty. And then, He was Concerned about not only the theory of Neo-Confucianism but also the practice of that. Theretore, his Administration thought is very important. Firstly, he asserted the theory of Reformation by gradual progress. This means the preparation of inward-condition for the success of Reformation and the transformation of Human Being. Secondly, his Administration thought is the standard of common sense, but it is excellent considering the limit of times. Thirdly, he attempted to establish public order thought the distinction of truth-falsehood and that of a wise man- a foolish man. Lastly, he emphasised that the opinion of speech was the Key for the welfare of the state, and he maintained extensive opening of speech, which is of importance in our times.

Pearlite성장속도에 미치는 합금원소 첨가효과의 속도론적 고찰

南勝義,安東勳 弘益大學校 1982 弘大論叢 Vol.14 No.2

The addition of an alloying element results in remarkable reduction of the rate of pearlite growth. In this paper, the effects of alloying elements on the kinetics of pearlite growth are investigated for Ni, Mn, Si, Cr, Mo. The mechanism for the effect of alloying elements is studied with a data or growth velocity and interlamellar spacing. The most important results in this paper are as follows. Strong carbide forming elements change the boundary (interfacial) diffusion for volume diffusion of carbon in the range of low temperature(below the Tp temperature) because the carbides prevent a cargbon from diffusing by interfacial route. In the systems that involve the elements which are not strong carbide formers, it is thought that the reactions are proceeded by a interfacial diffusion model with an activation energy of about 24,000 cal/mol.

退溪哲學의 理에 관한 考察

黃義東 청주대학교 인문과학연구소 1987 人文科學論集 Vol.6 No.-

Yi-Hwang philosophy represents Korean philosophy in company with Yul-Gok(栗谷)philosophy. Yi-Hwang illustrates the form of Existence-structure of all things from I and Ki(氣)as well as the traditional Confucianists. But he attaches great importance to the I. Therefore, the writer intends to examine the I in Yi-Hwang philosophy multilaterally. 1. Yi-Hwang states the relative I in the structure of the profound harmony of I and Ki, in spite of it, he emphasizes the absolute I that can exist without the Ki. 2. Yi-Hwang explains the I as Being-principle and Ought-principle, but he rather puts a stress on the Ought-principle than Being-principle. 3. Yi-Hwang makes plain his I-Ki doctrine in Cosmology and the theory of Human Nature, but he concentrates upon the I in the theory of Human Nature. 4. Yi-Hwang claims the action of the I, in that stand point, he differs from Chutzu(朱子)and Yul-Gok(栗谷). It is the distinctive feature of Yi-Hwang philosophy. But it has some problems logically. Eventually the above things originates from the ethical viewpoint of Yi-Hwang philosophy. Besides, they have the meaning of supplement of Chu-tzu's in sufficiency.
