This study was conducted to monitor the irrigation water qualities along Dong-Jin river watershed. The water quality was surveyed at 6 sites from April to september during 1994∼1998. And the results were as follows : In July and August, water quality was better than that of any other months due to dilution with rainwater. Whereas, it became worse in April but it involved lower contents than limitted contents affected to the crop damage. Content of inorganic components was higher at Jeong-up and Won-pyeong stream. The reason for it that Jeong-up stream was deteriorated with sewage water from Jeong-up city, and Won-pyeong stream has narrow width. Water quality in upstream of Dong-Jin river, was evaluated best conditions in all sampling sites. For investigated period, water quality got worse from 1994 to 1995 but it was getting better to 1998 after 1995, especially at Jeong-up stream. The total equivalent of cation and anion was the highest at April through all months and at Jeong-up stream in sampling sites. Equivalent ratio of cation to anions(∑C/∑A) was higher at May than any other months and lower at Won-pyeong streams than any other sites. The value of most inorganic components was highly correlated with those of other components. But the value of NO₃^--N was not correlated with that of most components, and PO₄^(3-)-P was not correlated with COD, NH₄^+-N, NO₃^--N, SO₄^(2-_.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

한민족공동체 형성과제와 민족정체성 문제

정영훈 在外韓人學會 2002 在外韓人硏究 Vol.12 No.2

한민족공동체란 전세계에 흩어져서 살고 있는 한민족 성원들을 공동 번영을 위하여 서로 돕고 협조하는 하나의 공동체로 결속시키자는 취지 하에 제기되고 있는 용어로서, 지금 무한경쟁의 세계화 시대를 헤쳐갈 수 있는 민족적 생존발전 전략의 하나로 그 의의가 부각되어 가고 있다. 한민족공동체란 현실적으로 볼 때, 한민족이라는 민족적 정체성을 공유한 사람들로 구성된 상호협조의 연결망 또는 유대체제를 가리킨다. 따라서 성원들에게 공유된 민족정체성의 내용과 강도에 의해 그 성패와 방향이 결정된다고 해도 과언이 아니다. 이 연구는 한민족공동체를 형성하는 과제와 관련하여 제기되는 민족정체성 문제를 검토해본 것이다. 여기에서는 (1) 한민족공동체의 아이디어가 추구하는 이상과 과제에 대해 개략적으로 설명한 뒤, (2) 민족정체성의 개념과 의의 및 그것의 유지·소멸에 관여하는 요인들에 대해 살피고, (3) 한민족공동체 구성원으로서의 정체성은 지금 어떤 상황에 놓여 있는지의 문제와, (4) 한민족공동체의 민족정체성 형성을 위해서는 어떤 방향 설정과 노력이 필요한가라는 물음들을 중심으로 살피고 있다. 결론적으로 이 연구에서는 지구촌에 거주하는 다양한 한민족 성원들이 공유할 수 있는, 그리하여 모두를 하나의 공동체로 결속시킬 수 있는 민족정체성 내용을 채우는 작업이 시급하다는 점을 강조하였다. The idea of Global Korean Community is raising with the belief that the globally dispersed Korean people must be unified and seek the common benifit and prosperity. It is being watched especially as a strategy of national survival and development in the age of globalization and borderless struggles. The idea of Global Korean Community demands national solidarity and cooperation to the Korean people. And it also urges the positive national identity based on national homogeneity and we-feeling. This paper discusses the problem of national identity in reference to the idea of Global Korean Community which is raised actively since 1990. The idea of Global Korean Community requires nation members to love each other, to concede each other, and to stand together. But these virtues can only spring up when there are strong community spirit and national homogeneity. This paper considers the condition of Korean people's national identity and discusses the contents of it, and will inquire how can we make it strong.

강영구,김정훈 한국안전학회 2004 한국안전학회지 Vol.19 No.2

The formation of rust on metallic substrate is known to cause the damages and destructions of raw materials, which is one of the leading reasons of structural collapses and many kind of hazards in modem industry. Polymer gels with rust removing effects were compounded in this study by employing various kinds of acids like hydrochloric acid, phosphoric acid, gluconic acid, oxalic acid as the rust removing ingredients. TEA(Triethanolamine) as dispersant and hydrophilic chemical were used for effective gelation of acids. Also corrosion inhibitor was added to enable the coating effect and to improve rust removing effect on metallic surface. In order to investigate the rust properties on metallic substrate, artificial rusts were prepared in salt solution, using iron, copper, aluminium and brass as the base metals. The properties of gel compounds were checked by gelation, pH, viscosity, morphology property and rust removing test. Developed gel compounds in this study have a good rust removing property, showing a strong adhesion on horizontal and vertical metallic surface, and can be easily rinsed off by water.

Macrophge에서 IL-1과 heat shock protein의 상관관계

이정범,민영기,양훈모 순천향대학교 교수학습개발센터 2004 Journal of Soonchunhyang Medical Science Vol.10 No.3

The macrophage plays an important role in lipopolysaccharide (LPS)-induced fever. Fever formation is attributed to macrophage activity. The purpose of this study is to examine whether induced fever has the charateristics of self-restriction during the process of a fever response. The result of methy-[^(3)H]-thymidine incorporation in RAW 246.7 cells showed that the proliferation of the macrohage was suppressed by a heat load of 39℃ for 2 hr. Enzyme-linked immunosorbent assay (ELISA) showed that the activity of IL-1 secretion induced by LPS was also suppressed by heat load. Suppression of activities of the macrophage including proliferation and secretion suggest that negative feedback loops exist where the end product, heat, may act back on the macrophage and finally result in the subsiding of a fever. The induction of heat shock protein (hsp70) by heat shock in the macrophage was detected by Western blot and Northern blot analysis. In U-937 cells, the increase of hsp70 band appears to be related to the extent of inhibition of IL-1 secretion. It is assumed that IL-1 secretion from the macrophage which effects the induction of fever, has a close relationship to the induction of hsp70.

Background and Objectives : Recently, the incidence of breast cancer is gradually increasing in korea. Many patients visit the hospital with a fear of breast cancer, if she had the pain in her breast. But Breast pain is not a cardinal sign of breast cancer. Only 7% of patient in breast cancer has breast pain. Materials and Method : To know the clinical effects of gamma-linolenic acid(GLA), we analyzed the medical records of 55 cases with breast pain, who visited the outpatient clinic of Chosun university hospital, between July of 1999 to December of 1999. Of the 55cases of breast pain, we analyzed 26 cases of patient with breast pain who was treated with GLA for 2 month and we excluded patients of breast pain who had breast mass or were treated with other drug. Results : 2 Patients we are dropped out because nausea and vomiting were developed, 4 Patient with breast pain were treated with GLA for 1 month, and relieved completely from mastalgia and 8 patients with breast pain were treated with GLA for 2 months and breast pain was relieved completelys. 4 patient had treatment for 2 months, were relieved slightly. But 8 patients with breast pain didn't reveal the relief of symptom after the intake of GLA. Conclusion : We conclude that GLA could be considered a first line drug in patients with mastalgia.
