Patients with gingival overgrowth are easily seen in dental clinics. Cyclosporin-A (CsA), a widely prescribed immunosuppressant induces gingival overgrowth in up to 35% of patients with medical history of organ transplantation. The immunosuppressant CsA can transform genetic expression of gingival fibroblasts, resulting in gingival overgrowth. Meticulous plaque control is recommended for treatment of gingival overgrowth. Substitution of the drug or surgical procedures such as gingivectomy and periodontal flaps should be considered after re-evaluation. Azithromycin is often recommended as a supplementary drug to reduce this side effect. Recent studies show that tacrolimus can be a more economic, efficient and safe substitute for CsA.

The main target to do this analysis is to find out the competitiveness between 2 countries(Korea and USA) in the ship business industry. Ever since free from Japanese empire domination of modern history in Korean peninsular, Korea has been strong relationship with USA almost every fields. The purpose of this research is to realize which country is more competitive between 2 country's trade structure. This research conducted for period from 2000 to 2016. Expecting effect is to learn how to improve ship industry for 2 countries. Research method is used by comparative advantage trade theory. Even though Koran government has been accomplishing trade stimulus environment against USA ship industry, it is research limitation that overseas productions both Korean & USA are not available due to company business strategy. From early 50's, every USA industries hold a dominant position so far. Now, Korea is comparative advantage against that of USA in the field of ship industry. Sound competition relationship is good for both 2 countries for mutual benefits. The future prospect is Korea needs export market diversification to enlarge economic growth in the long run.

Objectives : It is known that the prevalence of diabetes mellitus(DM) appears to be rapidly increasing in recent times in Korea, presumably due to a westernized diet and change of life style followed by rapid economic growth. Based on the Seoul male cohort which was constructed in 1993, this study was conducted to estimate the annual incidence rates of DM through 4 years' follow up and to determine which factors are associated with DM risk in Korean middle-aged men. Methods : Among 14,533 men recruited at baseline, 559 were excluded because they reported a history of diabetes or were found to be diabetes at 1992 routine health examination. During 4 years' follow-up, 237 incident DM cases were ascertained through chart reviews and telephone contacts for those who have ever visited hospitals or clinics under suspicion of DM during 1993-1996 and the biennial routine health examinations in 1994 and 1996. Results : In this study the annual incidence of DM among the study population was estimated to be 0.5 per 100. This study showed that fasting glucose level at initial baseline examination was a powerful predictor of risk for diabetes several years later(fasting blood glucose of $\geq$ 110 mg/dl compared with $\leq$ 80 mg/dl, Hazard Ratio[HR]:15.6, 95% Confidence interval[CI]=9.1-26.6) after considering potential covariates such as age, family history, smoking and alcohol history, body mass index, physical activity, total energy intake, and total fiber intake. Adjusted hazard ratios of family history of diabetes was 1.95(95% CI=1.38-2.75); of obesity as measured by BMI(BMI $\geq$ 25.3 compared with $\leq$ 21.3) was 7.19(95% CI=3,75-13.8); of weight change during middle life(>10kg compared with $\leq$ 5) was 1.77(95% CI=1.16-2.69); of smoking(current vs none) was 1.93(95% CI=1.06-3.51); and fat intake(upper fertile compared with lower fertile) was 1.88(95% CI=1.01-3.49), while fiber intake was associated with the reduced risk(HR=0.36, 95% CI=0.19-0.67). Conclusion : The factors identified in this study indicate that the greatest reduction in risk of diabetes might be achieved through population-based efforts that promote fiber intake and reduce obesity, smoking, and fat intake.

Peste des petits ruminants (PPR) is considered to be one of the main constraints to enhancing the productivity of goats and sheep in regions where it is present and becoming endemic. PPR was recognized in Pakistan in early 1990s but got importance during the Participatory Disease Surveillance (PDS) of Rinderpest Eradication Campaign. Lot of research work has been initiated during last decade towards disease epidemiology, risk factor recognition, laboratory diagnosis, vaccination and demonstration of control strategies. Although there are ongoing projects working towards the progressive control of the disease in country yet there is need to have a national level control program for PPR. Also there is need to have comprehensive social economic surveys, disease hot spot recognition and identification of role of other species in disease transmission. With combined efforts of local and national authorities and political will, there is high likelihood that this devastating disease can be controlled and eventually eradicated in near future.

Rockfall mitigation methods have been widely constructed along railway lines but aren't estimated with any economic analysis methods up to now. Therefore, this study applied a benefit-cost analysis to rockfall mitigation method to determine whether it is indeed an economically efficient construction. The Benefits were estimated based on data collected from disaster history, and included three types of benefits that are originated by reduction of train accident, train delay and rockfall removing cost. The costs included both construction cost and the maintenance cost of the selected method. This analysis could clarify the investment effect of rockfall mitigation method that would be built at rockfall prone slope.

The American ginseng is getting popular in the world market with cooling effects. This paper study history of the cooling effect of American ginseng. Most references include one's assertion on the cooling effect of American ginseng based on the old chinese believe. However, American ginseng was discovered in 1716 and export to China from mid 18 century. Concerning on the time period for clinical demonstration to get people's believe, it is not sufficient to conform the cooling effects of American ginseng. That is why the American ginseng was sold as an inferior goods compare oriental ginseng until mid 1970s. United State FDA also does not certify any effectiveness of Ginseng yet. However, it is important to study on the American ginseng because of rapid growth in the world ginseng market.

Capacitor switching is essential for the economic operation, and proper voltage control of KOREA electric utility distribution system. Voltage transients produced by capacitor switching (around 2.0 per unit at substation and 2.5 or less per unit at customer site, and lasting less then 1ms) do not have the magnitude or duration to interfere with the operation of computers, but they do disrupt the operation of adjustable speed drivers. The result of our research, ASD manufacturers should team from the computer industry and design products that will operate satisfactory in the electrical envelopment in which they will be placed. In this case history, the inductors on the input to ADSs in order to prevent nuisance tripping from capacitor switching(and other causes within the apartment) proved to be an effective, low-cost solution.
