관비재배와 저면관수인 ebb & flow, C-형강의 재배방식에 따른 고품질분화 생산을 위한 재배농가의 경제성을 분석하였다. 이를 위해 화훼농가의 비용구조를 분석하였고 자본 회수기간 및 내부수익률의 추정, 관수에 따른 인건비 절감 효과를 분석하여 재배방식에 따른 경제성을 비교하였다. 10a(991.7m²) 규모의 자동온실에 대해 관비재배방식을 선택한 시클라멘 재배농가의 총 비용은 9,993.8만원으로 추정되며, 이 중 시설비는 74%(7,410만원)를 점하고 연간 2,583.8만원의 경영비를 지출할 것으로 예상된다. 반면, C-형강방식을 선택한 재배농가는 초기 시설비용으로 약 8,520.0만원(총비용의 약 70%)을 지출하고, 매년 경영비로 3,597.0만원을 지출할 것으로 추정된다. 한편, 투자자금에 대한 자본회수 기간을 분석한 결과 10a 규모의 자동온실에서 시클라멘을 재배하는 농가에서 관비재배방식 혹은 C-형강방식을 선택할 경우에는 초기시설투자비 회수기간이 약 4 년 정도 소요될 것으로 예측되며, ebb & flow 방식을 선택할 경우에는 약 5년 정도의 시간이 소요될 것으로 예상된다. 또한, 내부 수익률을 추정한 결과 ebb & flow시설과 C-형강시설을 5년과 6년씩 사용한다고 가정할 경우, ebb & flow시설의 내부 수익률은 각각 9%와 14%로 나타났고, C-형강시설의 경우에는 각각 13%와 17%로 나타나 시중의 저축성예금 수신금리 4.82%와 비교하여 경제성이 높은 것으로 분석되었다. Economical efficiency for production of high quality-potted plants was analyzed by types of irrigation system such as conventional fertigation, ebb & flow, and C-channel as subirrigation systems. After cost structure was analyzed, payback period of capital, internal rate return (IRR), and effects of reduced labor cost were estimated. The gross cost of cyclamen-producing farmers using hydroponic systems in automated greenhouses (10a) was about 100 million won. Of the gross cost, installation and operation costs occupied 74% and 25%, respectively. In the C-channel subirrigation system, gross cost was 120 million won approximately. Installation and operation costs occupied 70% and 30%, respectively. Payback period of capital was 4 years for fertigated irrigation and C-channel subirrigation system, whereas it was 5 years for ebb & flow. IRR of ebb & flow and C-channel subirrigation systems was higher than the interest rates of 4.82%, indicating economic efficiency.

Aims: Chronic Hepatitis C Virus (HCV) infection increases the risk for progressive liver disease, hepatocellular carcinoma and negatively impacts the patient’s quality of life. HCV treatment is evolving with direct acting antivirals but IFN based therapy has been the standard of care for many years and remains available in some countries. The MOSAIC study aims to characterize patients with chronic HCV infection and assess the impact of IFN-containing treatment on health-related quality of life, work related productivity and health care utilization. Methods: MOSAIC is an international prospective multicenter observational study that has been conducted in 20 countries. Consecutive patients with chronic HCV infection were enrolled and those who initiated an IFN based regimen were prospectively followed for 48 weeks. We report results from the Korean cohort Results: 100 patients were enrolled: 86 were treatment naïve and 14 were treatment experienced. 33 patients initiated an IFN based regimen: 6 patients started IFN + RBV, 26 patients started Peg-IFN + RBV, none started Peg-IFN + RBV + DAA and 1 patient received other treatment. Among the treated cohort, demographic and disease characteristics were the following: the mean age was 54.5 years; 14 patients were male. 14 had minimal or no fibrosis, 2 portal fibrosis, 3 bridging fibrosis and 6 patients suffered from cirrhosis. HCV Genotype distribution was as follows: genotype 1: 11; genotype 2: 19 and genotype 3: 3. Table 1 describes the results at baseline and changes over 4, 12 and 48 weeks and end-of-treatment (EOT) for the quality of life and work productivity outcome measures (EQ-5D-5L, HCV-PRO and WPAI). Conclusions: Results from the Korean cohort of the MOSAIC study show a moderate trend for deterioration of health-related quality of life and work productivity associated with IFN based treatment for patients with chronic HCV infection during treatment period.

<P>In the previous COREA-TAXUS trial, a 6-month adjunctive use of celecoxib reduced target-lesion revascularization (TLR) without increased thrombotic risk. We aimed to confirm the effects of 3-month celecoxib in patients receiving drug-eluting stent (DES) implantation in the larger prospective, randomized trial.</P>

Purpose: The purpose of this study is to identify the effects of interaction between middle and high school golfers and sponsors on performance and stress. Method: Collected data was analyzed using SPSS and AMOS program. Exploratory and Confirmatory factor analysis were performed to verify the viability and reliability of questionnaire. Descriptive statistics analysis and frequency analysis were conducted to examine the personal characteristics of golfers. Independent t-test was conducted to analyze the influences to performance and stress of middle and high school golfers. The relation of parents interaction, coach interaction, performance and stress were analyzed and pearson correlation among subitems was analyzed. Multiple regression analysis was performed to analyze the effects of interaction between middle and high school golfers and sponsors on performance and stress. Statistical significance level was set as p<.05. Result: The results from this study are as follows. First, Statistically significant difference of stress level was found between male and female golfers. Second, family affection, support, communica-tion, technique guidance, encouragement, conversation and trust factors were statistically sig-nificant in terms of the effects of interaction between middle and high school golfers and sponsors on performance. Third, communication, family affection, support, trust, encouragement, technique guidance and obsession factor were statistically significant regarding the effects of interaction be-tween middle and high school golfers and sponsors on stress. Fourth, interaction between middle and high school golfers and sponsors affects performance and stress. Conclusion: The result shows that the interaction between golfers and sponsors enhanced game performance and reduced player``s stress. Performance and stress are important factor for golfers to continue their career. Therefore, the importance of interaction between middle and high school golfers and sponsors should be emphasized to interact more effectively. Development of inter-action program is needed to enhance their performance and reduce stress.

<P><B>Aims</B></P><P>DJ-1/park7, a multifunctional protein, may play essential roles in the vascular system. However, the function of DJ-1/park7 in vascular contractility has remained unclear. The present study was designed to investigate whether the DJ-1/park7 is involved in the regulation of vascular contractility and systolic blood pressure (SBP).</P><P><B>Methods and results</B></P><P>Norepinephrine (NE) elevated contraction in endothelium-intact vessels in a dose-dependent manner, to a greater extent in DJ-1/park7 knockout (DJ-1/park7<SUP>−/−</SUP>) mice than in wild-type (DJ-1/park7<SUP>+/+</SUP>) mice. Acetylcholine inhibited NE-evoked contraction in endothelium-intact vessels, and this was markedly impaired in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP>.

Histone deacetylase (HDAC)-1 recruitment and H3 histone acetylation at the eNOS promoter were elevated and diminished, respectively, in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP> controls. Moreover, SBP was significantly elevated in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP> controls, but this elevation was inhibited in mice treated with valproic acid, an inhibitor of Class I HDACs including HDAC-1.</P><P><B>Conclusion</B></P><P>These results demonstrate that DJ-1/park7 protein may be implicated in the regulation of vascular contractility and blood pressure, probably by the impairment of NO production through H<SUB>2</SUB>O<SUB>2</SUB>-mediated epigenetic inhibition of eNOS expression.</P>
