Background and Objectives : Cigarette smoking is a major factor and the most modifiable risk factor for atherosclerosis. Endothelial dysfunction is an early event in atherosclerosis, before the structural change of the systemic arteries. We hypothesized that endothelial dysfunction might be present in the systemic arteries of young adult smokers and that this might be dose-dependent phenomenon. Therefore, we try to certify that smoking is associated with endothelial dysfunction in healthy young adults without other risk factor of atherosclerosis. Subjects and Methods : we studied noninvasively 29 subjects aged 3 to 4 decades without other risk factor of atherosclerosis, they were composed of the two groups, current smokers(n=15) and nonsmokers(n=14). Smoking history varied from 3 to 20 pack years. Using high-resolution ultrasound, vessel diameter and mean flow rate were measured at rest, during reactive hyperemia(with flow-mediated endothelium-dependent dilation), and after sublingual nitroglycerin(NG-induced endothelium-independent vasodilation). Result : Flow mediated endothelium dependent dilation was observed in the control subjects (9.4±3.44%) but was impaired in the smokers(5.8±2.51%)(p=0.004). NG-induced endothelium independent dilation is no difference in all subjects. Conclusion : Cigarette smoking is associated with endothelial dysfunction in healthy young adults.

Background : Patients with chronic renal fialure have a substantially elevated risk of death from cardiovascular diseases than do the general population. the patients with chronic renal failure are at significantly increased freqeuncy of hypertension, hyperlipidemia, and diabetes mellitus which are known to the risk factors of the coronary artery diseases, and the prevalence of the coronary artery diseases in chronic renal failure patients is highly associated with the hemodynamic disorder and metabolic abnormalities. therefore we expected that the coronary angiographic findings in patients with chronic renal failure should be different from the general population (control groups) and investigated the risk factors contributing to coronary artery diseases. Method : we have retrospectively compared the coronary angiographic findings of 44 patients with chronic renal failure on hemodialysis with that of 88 patients in the general population and investigated the factors contributing to the development and acceleration of coronary artery diseases in patients with chronic renal failure Result : Hypertension and diabetes mellitus which is risk factors for coronary artery disease is significantly increased in patients with chronic renal failure, in coronary angiographic finding the severity of the lesion is worse. the incidence of PCI or CABG of patients with chronic renal failure is more than that of control group but statistically no difference between patients with chronic renal failure and control group. the sex, the duration of disease, the duration of dialysis, serum creatinine in patients with chronic renal failure have no correlation to the prevalence of coronary artery disease and severity of lesion. hyperglycemic patients with chronic renal failure have high incidence of coronary artery disease and are worse in the severity of lesion Conclusions : There is significantly increased the pevalence and severity of involving multiple coronary artery diseses in hyperglycemic patients with CRF.

Incontinentia pigmenti achromians(IPA) or Hypomelanosis of Ito is a very rare neurocutaneous syndrome which is often associated with cutaneous, cerebral, musculoskeletal and ocular abnormalities. It is assumed that it is autosomal dominant of inheritance in character. There is also a relationship between IPA and incontinentia pigmenti(IP). However, the etiology of IPA is not known. We describe a 4-year-old girl with myopia, esotropia and retinal pigmentary degeneration in addition to the hypopigmented skin lesion of IPA, and reviewed clinically the cases of IPA in this article.

The antibacterial effect amino acid-copper(Ⅱ) surfactant on fish pathogens was studied. Fish pathogens of Edwardsiella tarda, Vibrio anguillarum, Aeromonas hydrophila and Streptococcus sp. were selected, cultured in nutrient agar and adjusted at 2 × 10 exp (5)∼10 exp (6) CFU/㎖ in phosphate buffer saline before the addtion of amino acid-copper(Ⅱ) surfactant with different concentrations. All tested pathogens died within 1 hour with 1 ppm of amino acid-copper(Ⅱ) surfactant. In comparison with formalin and ET, amino acid-copper(Ⅱ) surfactnat was more effective in antibacterial capacity.

강릉남대천의 BOD를 1990년 4월부터 1993년 12월까지 모니터하였다. 강릉수력발전소의 발전수 방류 결과, 방수구와 홍제보의 BOD는 증가하는 경향을 보였으나, 하구의 BOD는 감소하는 경향을 나타내었다. 회귀분석에의하면 방수구와 홍제보의 매월 BOD 증가율은 공히 0.031mg/l이었으며, 하구에서의 매월 BOD 감소율은 0.071mg/l였다. The BODs of Namdaecheon Stream, Kangnung were monitored from April, 1990 to December, 1993. BODs at water outlet and Hongjebo were gradually increased, while BOD at estuary was decreased due to water discharged from Kangnung hydropower plant. The increasing rates in BOD at water outlet and Hongjebo were both 0.031mg/l month and the decreasing rate at esturary was 0.071mg/l month by linear regression analysis.

According to the increasement of the large web application development, there have been proposed some methodologies that help proper development and maintenance. We classified application into three domains and proposed an application developing method. This component-based developing method can improve sharing and reusability. Each developing phases are composed of application design, navigation design, display design, implementation and maintenance.
