It is important to know the impacts of acid rain because of soil acidification, reduced biological productivity. Many researchers were interested in regional acid problems, and former research were focued in short-term trends of acid rain. It is not easy to evaluate acid rain problems because of many parameters relating to meteorological factors, which are wind, temperature, humidity and other factors. Rainfall sampling for this study was done from September 1933 to December 2000 in Dong-A University, Busan. All Samples were collected in separately to early fraction and succeeding fraction. Also, the samples were measured for pH, and EC, cations and anions were analysed by ion Chromatography.

The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

Background: For effective education of social medicine, new and more efficient means of education are needed because social medicine consist of diverse background academics . Metohods: Workshop based lecture was carried out twice in social medicine class for medical students and was assessed with questionnaires survey. Results: Half of the students were satisfied with workshop-based learning and required more discussion time and pre-information. Conclusions: With some improvements, workshop-based adult learning method is expected to bring effectiveness in social medicine education.

Background : The amount of pesticide to be produced and consumed have rapidly growed in Korea and the evidences for pesticide intoxication to human body, natural environment and consumers have evoked. But the studies concerned to pesticide intoxication are inactive. So, we conducted this study about the determinants of awareness and performance for prevention of pesticide intoxication. Methods : The study conduced during the period from July to August 2007 with population consisted of 111 farmers. The toolkit was produced through referencing previous studies. Data analysis was performed with t-test, ANOVA and multiple linear regression analysis using SPSS 14.0K program. Results : The mean awareness score was 3.07 ± 0.75, the mean of total performance score was 2.72 ± 0.69, mean of subtotal performance score for keeping safety guideline was 2.72 ± 0.69 and mean of subtotal performance score for wearing protective equipments was 2.43 ± 0.83. Awareness score was associated with sex, age and family income. Female, older people and people with high income were tend to show low awareness score. Performance score was associated with sex, family income and educational level. Female, people with low education and high income were tend to show low performance score. Conclusion : We concluded that educational effort for noticing the harmful affects of pesticide, the importance of keeping safety guideline and wearing protective equipments to farmers especially female, older people, people with low education and high income were significant factors for prevention of pesticide intoxication.

Objectives : This study was conducted to estimate the comorbidity rate of ADHD in a group of patients with alcohol dependency and to find out the characteristics of alcoholic patients with ADHD using the diverse clinical and genetic variables. Methods : Eighty five patients with alcohol dependency were recruited from 4 mental hospitals in Kyoung-Nam and Kyoung-Ki province. For the evaluation of ADHD symptoms in both childhood and adulthood, the highly structured Diagnostic Interview Schedule for Children-IV (DISC-FV)-ADHD module was used. The various standardized scales and questionnaires were also applied to evaluate the comorbid conditions and psychopathological status. All the subjects' blood was collected and genetic study for the polymorphism of DRD2, TH, 5-HTTLPR, COMT, ALDH2 was performed. Results : 1) The comorbid rate of definite ADHD in alcoholic patients was 38% (28/85). 2) The frequency of unmarried status was significantly higher in ADHD group compared non-ADHD group. 3) The onset of pathologic drinking and auditory hallucination was significantly earlier in ADHD group than non-ADHD alcholic group. 4) In ADHD alcoholic group, antisocial behavior was more frequently reported, and the score of co-dependency scale, depression/anxiety, aggression and obsessive compulsive drinking scales were significantly higher compared to non-ADHD alcoholic group. 5) No signficant difference was found in the frequency of polymorphic alleles in COMT, DRD2, 5-HTTLPR, ALDH2, TH between ADHD and non-ADHD alcoholic group. Conclusion : In alcoholic patients, the rate of adult type ADHD was higher than expected rate in general population. The alcoholic patients with ADHD suffered from more sever degree of alcohol dependency and earlier alcohol related problems. ADHD-alcoholic group showed higher diverse comorbid psychopathology and lower marital status compared to non-ADHD-alcoholic group. No difference, however, was found in genetic data between two groups.
정상면역을 가진 환자에서 발생한 복부대동맥의 진균 감염성동맥류 1예

감염성동맥류는 드물지만, 치명적인 질환이다. 진성 진균성 감염성동맥류는 더 드물게 발생한다. 진균감염은 사망률과 이환율이 매우 높다. 그러나 증상이 비특이적이고 일반적인 진단방법으로는 민감하게 진단이 되지 않기 때문에 종종 진단이 어렵다. 저자들은 면역이 정상이고 다른 위험인자가 없는 환자에서 복부대동맥에 발생한 진균성 감염성동맥류를 경험하여 이를 보고한다. 컴퓨터 단층촬영과 혈관 수술에 기초하여 진단하였으며, 수술 후 조직배양에서 균이 동정되지는 않았으나 절제한 혈관조직에서 칸디다 감염을 시사하는 발아가 있는 효모균이 관찰되었다. 한국에서 1988년에서 2007년까지 복부에 발생한 감염성동맥류 17증례를 고찰하였을 때 진성 진균성 감염성동맥류는 없었으며, 저자들이 경험한 것이 복부에서 발생한 진균감염성 동맥류로는 첫 증례이다. Infected aneurysms are uncommon, frequently fatal lesions. "True" fungus-infected aneurysms are even rarer. Fungal infections have high morbidity and mortality. However, diagnosis is frequently difficult, since the symptoms are non-specific and standard diagnostic procedures are often insensitive. We experienced a patient with persistent fever and negative blood cultures. The patient was immunocompetent and had no risk factors, and was diagnosed with a fungus-infected aneurysm based on computed tomography and vascular surgery. The vascular tissue revealed some narrow-based budding yeast within the thrombus, suggesting Candida infection. Seventeen cases of infected aneurysm of the abdomen were reported in Korea from 1988 to 2007, although none were "true" fungus-infected aneurysms, making this the first fungus-infected aneurysm of the abdomen in Korea. Prompt diagnostic procedures and aggressive treatment modalities are necessary for patients with occult infection and negative blood cultures, regardless of their immunocompetence, because of the high morbidity and mortality of this condition.

The spectroscopic properties of 9 pads in a urine strip were studied to develop a urine analysis system. From the present work, we determined the wavelength range which could accurately distinguish the degrees of 9 test items. A computer simulation was performed to distinguish the primary color reaction in the urine strips by using the reflectance of the urine strips, the iuminous intensity of light-emitting diodes, and the spectral sensitivity of photodiodes. The simulation results agree well with the experimental results obtained by using a UV-Visible spectrophotometer.
