2007년 4월 이전까지 10~15년 동안 규격시설로 운영되어 오던 농가지도형 단동하우스에서의 보강지주 설치효과를 분석하였다. 이전의 연구로 적설하중에 대한 수식 계산을 통해 보강지주 설치 단동하우스의 추가적설심이 제시된 바 있으나 모델이 농가지도형 단동하우스 규격과 상이해 연구 결과를 농가지도형 단동하우스에 그대로 적용하기에 무리가 따랐다. 본 연구에서는 농가지도형 단동하우스를 3차원 강뼈대 구조물로 모델링 하여 보강지주 설치 효과를 분석하였으며 재하시험을 통해 해석결과를 검증하였다. 구조해석 결과, 단동하우스에 보강지주 설치 시 안전적설심은 오히려 줄어드는 것으로 나타났는데 파이프 체결 부에서의 집중 하중으로 지붕도리에 큰 응력이 걸리기 때문으로 보강지주 설치 시에는 지붕도리의 규격도 함께 강화되어야 할 것으로 판단되었다. 지붕도리를 강화하고 보강지주를 3~4m 간격으로 설치할 경우, 안전적설심은 기본모델에서 보다 2배 이상 높아지는 것으로 나타났다. 보강지주 규격별 농가지도형 단동하우스 5종의 안전적설심을 제시하였다.

Congenital hereditary disease is in devided into Infantile type and Adult type, Adult type is hidden for many years and keeps normal renal function till middle age. Cyst is stimultaneously made in both sides and becomes lowered in renal function in 30's to 40's. Infantile type is generally born with the big kidneys, renal failure, undergrowth of intrahepatic bile duct. Both infantile and childhood type have ureteral dilatation and portal hypertension In infantile type, it is mostly developed into renal failure, but generally faces death as a result of hepatic disease. The reason of death is that an abnormal condition of recessive autosome affects the liver and kidneys. While the incidence of infantile type is rare as $0.017{\sim}0.07%$ and it is autosomal recessive heredity, Adult type can rarely exist in infantile period. Though it exists in middle period, 50% of patients can live for 2-4 years after the first symptom incidence and 25% can less than 2 years. It is hard to cure completely in medicine and surgery. Three difficulties in familial incidence are comparative decrease of the donor who have no affection on renal transplantation. For another consideration it is to show the family history for several generations. We, the Med. Dept. of Dae Han Kyouk Life Insurance Co. Ltd., used the ultrasonic apparatus in diagnosing the one case of adult type bilateral polycystic kidney and then doubted the family history. As a result of inspecting the family we experienced bilateral polycystic kidney from 3 persons out of 4 who can be inspected. The results are as follows: 1) We could confirm the polycystic kidney from 3 persons out of 4(75%). 2) Then when they came for check up, chief complaint was the pain in all 3 cases(100%). 3) Accompanying disease was hypertension in 2 cases(67%). 4) In early disease incidence, we couldn't observe the specific change in pathological opinion. 5) All 3 cases are not accompanied with cystic lesion in liver, spleen, pancreas.

Background: Oral cancers account for approximately 2% of all cancers diagnosed each year; however, the vast majority (80%) of the affected individuals are smokers whose risk of developing a lesion is five to nine times greater than that of non-smokers. Tobacco smoke contains numerous carcinogens that cause DNA damage, including oxidative lesions that are removed effectively by the base-excision repair (BER) pathway, in which poly (ADP-ribose) polymerase 1 (PARP-1), plays key roles. Genetic variations in the genes encoding DNA repair enzymes may alter their functions. Several studies reported mixed effects on the association between PARP-1 variants and the risk of cancer development. Till now no reported studies have investigated the association between PARP-1 variants and oral squamous cell carcinoma (OSCC) risk in an Indian population. Materials and Methods: In the present case control study 100 OSCC patients and 100 matched controls were genotyped using PARP1 single nucleotide peptides (SNP's) rs1136410 and rs3219090 using TaqMan assays. Results: The results indicated significantly higher risk with PARP1 rs1136410 minor allele "C" (OR=1.909; p=0.02942; CI, 1.060-3.439). SNP rs1136410 also showed significantly increased risk in patients with smoking habit at C/C genotype and at minor allele C. Conclusions: The PAPR-1 Ala762Val polymorphism may play a role in progression of OSCC. Larger studies with a greater number of samples are needed to verify these findings.

Purpose: This research is performed through the analysis of the dental technology students' life-style factors of their daily lives that have a close relation with health, and the self-reported symptoms which are related to psychosomatic diseases, for the production of basic data for the change of life-styles and the development of educational programmes. Methods: This research has been performed through questionnaires from the beginning of October of 2014 till the end of November through the Dental Technology students of G-do, chosen by random sampling method after informed consent, where out of the 270 papers, 258 results were used for the analysis. Results: Firstly, the results of the research was as follows: Non-smokers accounted for 61.2%, student who did not do regular physical activities accounted for 50.4%, students who had sleeping hours of 6 to 7 hours accounted for 35.7%, students who eat snacks accounted for 63.2%, students who eat breakfast once to twice a week accounted for 30.6%, students who had an average number of drinks of once to twice a week accounted for 39.9%, and students with BMI of '$18.5^{\circ}{{\neq}}22.9$' accounted for 56.2%, being the highest. Secondly, in gender, smoking (p<.001), regular physical activity (p<.001), BMI (p<.001), eat snacks (p<.05), average number of drinks (p<.05), and of the health check-up, eat breakfast (p<.05), of the year level, eat snack (p<.01), BMI (p<.01), hours of sleep (p<.05), of major satisfaction, regular physical activity (p<.01), and BMI (p<.05), and there was a significant statistical difference, but there were no significant statistical difference in religion. Thirdly, of the bodily self-reported symptoms of the correlation analysis within the life-style variables and the self-reported symptoms, multiple subjective symptoms (I), respiratory (A), eye and skin (B), and digestive organs (C) were the highest in the correlation analysis with regular physical activity (p<.01), and of mental health, impulsiveness (H), mental instability (J), and depression (K) showed highest results in correlation analysis with regular physical activity (p<.01, p<.05), lie scale (L) and irregular and life (G) with eat breakfast (p<.01), and aggressiveness (F) with BMI (p<.01), showed highest results in correlation analysis. Fourthly of the Dental technology students' bodily self-reported symptoms, life-style factors which had a statistically significant effect appeared to be regular physical activity (p<.001) and BMI (p<.05), and of the mental self-reported symptoms, causes that did not have statistically significant effect appeared to be regular physical activity (p<.05) and eat breakfast (p<.05). Conclusion: This research concludes that in order to develop correct life-style habits for health promotion and reduce self-reported symptoms related to the Dental Technology students' diseases, education for the recognition of the necessity of self health promotion must be conducted, and a education programme scheme for the Dental technology curriculum for practicing the correct life-style habits in daily life is required.

It is well known that discard of seminal plasma from the semen and separation of motile sperm should be preceded before insemination for IUI or IVF. Till now, more than ten kinds of semen treatment methods have been developed. Of those, swim-up and Percoll methods have been used widely in ART laboratories as a routine semen treatment methods because of its advantages. However, there are reports that Percoll can make a genetic trouble because of its chemical structure and therefore the necessity has been arisen to substitute Percoll for other equivalent materials. This study was performed to evaluate the effects of three different sperm preparation methods (swim-up, Percoll and Sil-Select) on sperm motility, sperm recovery rate and fertilization rate. Also, the feasibility of using Sil-Select instead of Percoll in ART was evaluated. Each semen samples were divided into three fractions and motile sperm were recovered by swim-up, Percoll and Sil-Select gradient centrifugation methods. Normal and sub-normal criteria of fifteen semen samples and seventeen IVF cycles were included in these study. As results, no significant difference was found in sperm recovery rate in normal semen treated by a Swim-up, Percoll and Sil-Select method ($13.2{\times}10^6,\;17.5{\times}10^6\;and\;17.7{\times}10^6$ respectively). The initial sperm motility was 61.9% and this increased to 87.1%, 92.6% and 89.5% through Swim-up, Percoll and Sil-Select treatment, respectively. Higher motility was observed in Percoll and Sil-Select treated groups (81.5%, 79.2%, respectively) than swim-up group (66.8%) after incubation for 24hrs. In sub-normal group, sperm recovery rates were higher in Sil-Select group $(2.9{\times}10^6)$ than Percoll gradients group $(1.8{\times}10^6)$. In IVF cycles, the outcomes of fertilization using sperm treated by swim-up and Sil-Select group were similar (82.2%, 79.7% respectively). In conclusion, our results indicate that Sil-Select can be used as a substitute material for sperm preparation instead of Percoll.

Control of white rot which is one of the most serious apple diseases in Korea has mainly relied on periodical spray of protective fungicides. As the main inoculum source of the disease is pycnidiospores produced in the warts formed on affected stems of apple tree, it can be conceivable that inhibition of spore production might be an effective means for controlling the disease. Inhibitory efficacy of eight selected fungicides against sporulation of the fungus was assessed by counting the number of spores produced at detached warts treated with the fungicides of recommended dilution. They showed diverse effect on sporulation. Carbendazim and azoxystrobin suppressed sporulation almost completely, the former irreversively. Thiram and folpet promoted sporulation as producing much more number of spores than untreated control. Others showed almost no effect on sporulation. Effects of suppression and promotion in the sporulation shown by the fungicides on the control of white rot were examined by incidences of disease and infection at the plots adopted the spray programs of which the fungicide at late May was substituted by carbendazim, azoxystrobin, folpet and thiram, respectively. Disease incidence and infection frequency at the plots sprayed former two chemicals which suppressed sporulation were much lower than those of the plots adopted latter two chemicals and untreated plot at which the fungicide spray was skipped at that time. These facts were reconfirmed in the experiments conducted with carbendazim and thiram, in which 100 fruits were bagged just prior to each spray from late May to late July for elucidating the effect of the two fungicides on the action of subsequent ones. Disease incidence and infection frequency on the fruit bagged just prior to each spray were gradually increased as the seasons going on. The increase rate at the carbendazim plot was much lower than that of thiram. Especially, the fruit infected till late July at the carbendazim plot were almost completely cured by the three fungicides, iminoctadine-triacetate, tebuconazole and samzinwang, a combined formular of iminoctadine-triacetate and difenoconazole, sprayed at late July and hence. In thiram plot, infected fruit were also cured by the 3 fungicides but not remarkable. From these results, it can be concluded that control efficiency of white rot can be greatly enhanced by selecting the fungicide capable of suppress the sporulation of white rot fungus at the season when the mass dispersal of spores is not initiated.
