        농업용수 수질기준의 문제점 및 개선대책 : 외국사례와의 비교를 통해

        김진호,이종식,정구복,윤순강,고문환,심재천,권순국 한국국제농업개발학회 2003 韓國國際農業開發學會誌 Vol.15 No.3

        우리나라 농업용수 수질기준과 다른 국가 또는 농업관련 국제기구의 수질기준에 대한 비교분석을 통해 우리나라 농업용수 수질기준의 문제점 도출과 해결방안을 모색코자 본 연구를 수행하게 되었으며, 그 결과를 요약하면 다음과 같다. 1. 우리나라 농업용수 수질기준은 관개용수 수질기준이 아니고, 수원보호측면의 수질기준이라 할 수 있다. 2. 우리나라 수질기준중 유기물지표가 하천과 호소에 따라 BOD와 COD로 이원화되어 있고, 특히 COD의 경우 산화제로 KMnO4를 사용함으로써 효과적인 유기물지표로 활용할 수 없는 실정이다. 농업용수로의 활용측면에서는 K₂Cr₂O_(7)을 이용한 COD를 기준으로 도입하는 것이 유기물 분해능 및 수중의 유기물지표로 활용하고 있는 국제적 데이터 일치를 위해서도 타당하다. 3. 우리나라 농업용수 수질기준은 캐나다와 FAO에서 제시하고 있는 염류에 대한 기준은 거의 없는 실정이다. 또한 양이온에 대한 기준도 없다. 염류의 기준이 모든 이온 존재의 가능성을 의미하므로, 실험치 및 외국문헌에 의한 1.0dS/m수준을 한계농도로 선정해야 한다. 4. FAO와 캐나다에서 사용하고 있는 축산용수에 대한 수질기준이 없다. 5. 관개용 농업용수가 농업(작물)에 미칠 수 있는 영향을 평가하기 위해서는 수원별로 수질기준이 다른 것이 큰 모순이다. 따라서 관계부처에서는 부처간의 이해를 떠난 수질기준을 설정해야 한다. 6. 우리나라 농업용수 수질기준의 모순점을 극복하기 위해서는 농업의 안전성확보측면 위해 관개용수 수질기준과 축산용수 수질기준을 조속히 제정해야 할 것이다. Present problems and possible solutions on the Water Quality Standards for Agriculture in Korea, were identified in the study. Because the Ministry of Environment made the laws and standards without consulting the agri-scientists, among others, the water quality standards formulated were not suitable standards of FAO, Japan, Canada, and the likes. The BOD and COD are the organic materials indicators. In case of rivers, BOD are set for the indicator. And at reservoirs. COD are set. Especially. COD was analysed using KMnO₄It is not suitable oxidizing agent for COD. Because the oxidic capacity is very low. So, in most developed country, K₂Cr₂O_(7) is usually used to analyze COD. And the salts and cations are not belonged to the Korean Water Quality Standards for Agriculture. The water quality standards for agriculture have big differences among lakes, rivers and groundwater. To apply different standards by resources to evaluate the relationship between water and crops is conflicting. So, to overcome the these problems, the suitable water quality standards for irrigation and livestock should be set.

      • 머리염색이 인체에 미치는 영향

        윤형식,황성호,이현륭,김수호,박연석,권낙현,정호진,김동훈,노현주,홍성호,박병찬,이관,정해관 東國大學校醫學硏究所 2002 東國醫學 Vol.9 No.1

        일상생활에서 모발염색은 흔히 접할 수 있는 미용의 한 종류로 특히 젊은층을 중심으로 폭발적으로 유행하고 있다. 염색을 위항 사용하는 약제는 표백제와 발색제 등 각종 화학약품이 사용되고 있으나 이로 인한 건강장해에 대한 연구는 그리 많지 않다. 저자들은 염색이 인체의 모발건강에 미치는 영향을 파악하기 위하여 염색과 관련된 주관적 증상과 모발의 변화에 대한 실험적 연구를 시행하였다. 동국대학교 경주 캠퍼스 재학생 80명을 대상으로 설문조사를 시행하여 염색 유 ·무 및 염색 후에 경험한 증상에 대해 설문 조사하였고, 의과대학 재학생 46명을 대상으로 피부 반응 테스트를 실시하였다. 또한 염색 전후의 모발 탄성도를 측정하였고 모발의 상태를 파악하기 위해 전자 현미경검사를 실시하였다. 설문조사 결과 염색 전에 비하여 염색 후 안구혼탁, 안구건조, 시력저하, 발진 및 접촉성 피부염, 모발손상, 모근손상 등의 증상을 더 많이 경험한다고 호소하였다(p<0.05). 모발손상과 모근손상은 헤어드라이어 사용 빈도에 따라 증가하는 것으로 조사되었다(p<0.05). 피부반응검사에서 가려움증이 가장 많은 증상이었으며 이는 여성보다는 남성에서 높은 것으로 조사되었다. 염색 전후의 모발장력은 염색 전 134.5±10.37g, 염색 128.0±30.69g, 염색 이틀 후 112.5±19.69g으로 나타났다. 염색 전후의 모발의 전자현미경 케라틴 층이 현저히 감소하고 모발이 가늘어지는 차이를 보였다. 염색은 모발손상, 모발 케라틴 손상 및 모근 손상, 발진 및 접촉성 피부반응, 안구혼탁, 안구건조, 시력 저하를 유발한다. 따라서 염색약으로 인한 손상에 대한 주의와 예방이 필요하다고 생각한다. 예방대책으로 염색 전 피부테스트를 통한 적합성 여부를 판단하는 것이 필요하며 가급적 염색을 피하는 것이 좋을 것이다. 염색약에 발암물질이 포함되어있다는 보고도 있어 염색 제조사의 철저한 실험과 염색 물질의 선별이 염색으로 인한 부작용을 최소화하는데 중요한 역할을 할 것이다. Hair coloring has became one of the most popular cosmetic activities to younger generations during last decade. However, there are few studies on the health effect of widespread use of chemical dyes. This study was conducted to study the effects of hair coloring dye on hair and other systems. We conducted a questionnaire survey of 80 persons in Kyongju campus, Dongguk University. We have done open patch skin test on 46 medical students. We also conducted scanning electron microscopy to examine the hair strength and structure before and after hair coloring process. Injury of hair and hair bulb, contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity were the main symptoms complained after hair coloring (p<0.05). Injury of hair and hair bulb were increased by frequency of hair-dryer use(p<0.05). In open patch test, pruritus was complanined by more than half of the subjects. Mean strength of hairs before and after hair coloring was as follows; 134.5 (SD 10.37)g before hair coloring, 128.0 (SD 30.69)g immediately after hair coloring, and 112.5 (SD 19.69)g after two days. The scanning electron microscopic findings of hair surface before and after hair coloring showed decreased keratin layer and thinning of the hair. Hair coloring induces injury to hair, its keratin layer, and hair bulb as well as contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity. Therefore, we think that precaution is needed in use of hair coloring dye. To prevent complications induced by hair coloring dye, it is necessary, especially to those with allergy or skin disorders, to perform skin test before action and avoid hair coloring whenever possible. Longterm health effects of hairdye should be studied and manufacturing companies should try to minimize complications induced by hair coloring dye.

      • 내용기반 분류에 의한 비디오 검색 시스템 설계

        배종식,남윤성,양동일,최형진 강원대학교 정보통신연구소 2006 정보통신논문지 Vol.10 No.-

        We suggest how to search news data by dividing structurely, by classifying meaningly, and by itemizing them by contents. The structural division divides the scene using correlative information between frames such as the distribution of the space brightness and the irregularity of brightness, and time relation etc. The meaning classification means to classify the detailed contents of news video as articles comparing special information extracted frame key frame with previous knowledge information. This study classifies the articles as the anchor's scene and the non-anchor's scene using the character that the progress of news is repeated centering around the anchor frames by periods. We get the non-anchor's scene to search the news data itemizing speech scene, interview scene and general scene, and classifying as articles. Also, we use the function of searching for summary by news icons and search the caption by processing the integration of caption, and design them to be able to search the news video quickly classifying news video as contents and indexing them.

        신라화랑의 신체활동에 관한 연구

        김진범,이인희,윤동식 대한무도학회 2000 대한무도학회지 Vol.2 No.1

        This study aims to examine the background and die concrete physical activities of hwarang("flower of youth") of Silla for the purpose of deducing modem significance from a standpoint of the martial arts history. I have reached the following conclusions. First, the religious aspect of the hwarang was characterized by the factors of shamanism, taoism, and Buddhism. The actions of the hwarang as manifested in their physical activities originated from the ideological groundwork of the hwarangdo(hwarangship). The hwarangdo seems to have been based upon the racial tradition and belief for the express purpose of defending national territory and sovereignty by closely uniting and specially training the elite youth so that they could be of great use to the country not only militarily but socic-politically as well. When in perfect alignment with this supreme policy of the state, the hwarangdo seems to have functioned as the strongest internal movement - national movement. The central ideology of the hwarangdo were loyalty, filial piety, and mutual trust. Second, the physical activities of the hwarang may be classified into three categories - hunting, singing and dancing, and martial art. Hunting includes political and military methodology. Some hunting pictures of the Silla dynasty, however, showed scenes akin to recreation. Third, the physical activities of the hwarang had a close relation with education. It is worth notice that in training the hwarang not merely physical education but also moral and musical education were placed great importance on. On of the educational objectives in training the hwarang was apparently to produce Hercules or warriors that were m great demand in the country and society. The hwarng was supposed to be a youth of perfect health and undaunted courage and one who boldly stood up to an injustice. In short, the ideal the hwarang sought was to become a balanced personality with sufficient intellectual and emotional cultivation as well as being a master of martial arts by constantly practicing physical training.

        As a result of using such methods of study and analyzing the data collected, the fellowing conclusions could be drawn; First, the status of a boxer affects the extent of stress caused by his school life. Namely, the status of a boxer determines the extent of his school life stress, and non-boxers are more stressed by their school life. Second, the status of a boxer affects the extent of stress caused by his human relationship. Namely, the status of a boxer determines the extent of his social life stress. and non-boxers more stressed by their human relationship. Third, the status of a boxer the extent of the stress caused by his own problems. Namely, the status of a boxer determines the extent of his private life stress, and non-boxers are more stressed by their own problems. Fourth, the status of a boxer affects the extent of the stress caused by his living environment. Fifth, the status of a boxer affects the extent of the stress caused by his family life. Namely, the status of a boxer determines the extent of his family life stress, and boxers are more stressed by their family life. Sixth, the status of a boxer affects his self-respect at school partially. Namely, the higher the stresses caused by living environment and family life are, their self-respect at school tends to be lower. Seventh, the status of a boxer affects his self-respect amid peer group partially. Namely, the higher the stresses caused by school life, human relationship, living environment or family life are, their self-respect amid peer group tends to be lower. Eighth, the status of a boxer affects his self-respect at home partially. Namely, the higher the stresses caused by family life is, their self-respect at home tends to be lower.

        골아세포 MC₃T₃-E₁의 증식과 기능에 Insulin Like Growth Factor Ⅰ, Ⅱ 및 부갑상선 호르몬이 미치는 영향

        윤현구,정호연,양인명,김성운,김진우,김광원,김영설,최영길,서광식 대한내과학회 1992 대한내과학회지 Vol.42 No.1

        MC₃T₃-E₁골아세포군을 이용하여 IGF-Ⅰ과 Ⅱ를 투여하고 DNA합성과 골아세포기능을 측정하기 위해 PTH에 대한 C-AMP반응정도, alkaline phosphatase 활성도를 측정하여 다음과 같은 결과를 얻었다. 1) IGF-Ⅰ과 Ⅱ는 모두 DNA합성이 어느 농도까지는 증식효과를 나타내지만 그 이후에는 억제되는 양상을 보였다. 2) PTH에 대한 골아세포의 C-AMP반응으로 증가되었지만 IGF-Ⅰ과 Ⅱ의 투여시 농도변화에 따른 의미있는 변화는 없었다. 3) 본 실험의 조건에서 alkaline phosphatase 활성도는 증가되지 않았다. 이상의 결과로 MC₃T₃-E₁ 골아세포에 IGF-Ⅰ과 Ⅱ는 세포의 증식을 자극하여 PTH는 C-AMP생성을 촉진하는 효과가 있었다. The effect of insulin-like growth factor (IGF) Ⅰ and Ⅱ on cloned MC₃T₃-E₁ cells that had osteoblastic activity was examined by [³H] thymidine incorporation into DNA, cyclic AMP responsiveness to parathyroid hormone (PTH), and alkaline phosphatase activity. IGF Ⅰ and Ⅱ stimulated the growth and proliferation of osteoblastic cells at 20ng/㎖ and 50ng/㎖, respectively. We next examined the effect of IGF-Ⅰ and Ⅱ on the expression of osteoblastic activity. Adenylate cyclase response of PTH to IGF-Ⅰ and Ⅱ-treated cells showed maximal stimulation at 10 and 50㎚PTH, respectively, but IGF Ⅰ and Ⅱ induced limited activity of osteoblastic function. In conclusion, IGF-Ⅰ and Ⅱ were potent stimulators to the growth of osteoblastic cells but did not have an immediate effect on expression of osteoblastic function in this experiment.

        중증 외상환자에서 염기 결핍수치의 유용성

        문준동,김수진,문철규,최성혁,전정민,이성우,홍윤식 대한응급의학회 2001 대한응급의학회지 Vol.12 No.3

        Background: This study's objective was to determine the prognostic value of the base deficit measured in the emergency department(ED) and to determine whether base deficit can provide information not provided by advanced injury scoring system. Methods: This study was a retrospective analysis of data collected for two years. Thirty-two severe trauma patients who were admitted to the Emergency Department of Korea University Hospital were included in this study. The patients were divided into two groups: the normal base deficit group(-3 mmol/L to 3 mmol/L) and the elevated base deficit group(>3 mmol/L). The base-deficit value, age, sex, head injury, organ failure rate, and survival were considered, and the also Revised Trauma Score(RTS), Acute Physiology And Chronic Health Evaluation(APACHE II), and Injury Severity Score(ISS) were measured. Result: The elevated base-deficit group showed a lower survival rate and a higher organ failure rate compared to the normal base deficit group. Logistic Regression showed a strong association between base deficit and mortality rate. Among the previous injury scoring Systems(RTS, APACHE II, ISS), base deficit had the strongest correlation with RTS. By using base deficit value and the RTS together, we obtained a higher positive predictive value than that obtained by using base deficit or RTS alone. Conclusion: The admission value of the base deficit in the ED is a useful tool in predicting the outcome in severe trauma patients, and it can be an adjunct to previous injury scoring systems. As an advanced injury scoring System is developed in the future, the base deficit may have some significant role.
