가람 이병기 박사께서 유명을 달리한지도 어언 1년이 가까워 온다. 가람의 문하에서 수업한 한 제자로서 스승의 평생 수적을 수집ㆍ정리하여 보고 싶은 한가닥 생각은 스승을 잃은 애통한 마음과 더불어 날이 갈수록 더해짐을 느낀다.

Background/Aims: The reappearance rates of hepatitis C virus (HCV) RNA after a sustained virological response (SVR) have been reported to be 1-2%. We investigated the reappearance rate of HCV RNA after SVR in chronic hepatitis C (CHC) patients treated with pegylated interferon (PEG-IFN) and ribavirin. Methods: In total, 292 CHC patients who achieved an SVR after PEG-IFN and ribavirin treatment were included. They were treated with subcutaneous injections of either PEG-IFN-α 2a or 2b plus ribavirin orally. Liver function tests and qualitative HCV RNA assays were performed every 6 months during the follow-up period after an SVR. Results: Among the 292 patients, 224 (genotype 1, 92; genotype non-1, 132) were followed up for more than 6 months after SVR. These 224 patients were aged 48.1±11.5 years (mean±SD), and 129 of them were male. The median follow-up duration was 18 months (range 6-60 months). The reappearance rate of HCV RNA during follow-up was 0%. Two patients who achieved an SVR developed hepatocellular carcinoma during the follow-up period. Conclusions: An SVR was maintained in all CHC patients treated with PEG-IFN plus ribavirin during a median follow-up of 18 months. However, a screening test for hepatocellular carcinoma is needed for patients with an SVR. (Korean J Hepatol 2011;17:183-188)

<P><B>Abstract</B></P> <P>Two-dimensional transition-metal dichalcogenides (TMDCs) are very promising for photovoltaic (PV) applications due to their excellent light absorption properties and appropriate bandgap energy, Although multifunctional applications of TMDCs in photovoltaic devices have been achieved, the photovoltaic conversion efficiency under 1 sun is still very low with small active area because of their inexpedient high sheet resistance and limitation of synthesis techniques. In this study, we demonstrate uniform synthesis of 4-in. wafer-scale MoS<SUB>2</SUB> thin films by thermal decomposition of solution precursors. The solar cells are fabricated by transferring n-MoS<SUB>2</SUB> thin films on p-Si substrates to form p-n heterojunctions and then transferring Au nanomeshes prepared in a novel surface treatment as transparent top electrodes onto MoS<SUB>2</SUB>. The circular n-MoS<SUB>2</SUB>/p-Si heterojunction solar cell exhibited a power conversion efficiency of 5.96% at a diameter of 0.3 in. and proved to be easily scalable to 1-in. diameter with 5.18% efficiency. To the best of our knowledge, the solar cells of this study are the most efficient and the largest in all types of solar cells based on TMDC reported so far. Finally, based on finite difference time-domain simulation, we proposed a strategy for implementing n-MoS<SUB>2</SUB>/p-Si heterojunction solar cell with efficiency higher than 15% by introducing optimal doping control of n-MoS<SUB>2</SUB> and efficient anti-reflection layers.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The large scale, uniform (4-in.)

The Inhalation of certain freshly formed metal oxides can cause metal fume fever, which is an acute, self-limiting, flu-like illness. The most common cause of this syndrome is the inhalation of zinc oxide. The inhalation of zinc oxide can lead to tracheobronchiolitis, chemical pulmonary edema or to respiratory failure and acute respiratory distress syndrome(ARDS). We encountered a 43-years-old man who developed severe dyspnea after inhaling of zinc oxide while working for 5 hours in a closed space. He was diagnosed with ARDS and was treated successfully with glucocorticoid. We report a case of ARDS caused by the inhalation of zinc fumes. (Tuberc Respir Dis 2007; 62: 314-317)

Up-to-date artificial insemination (AI) using frozen sperm consider as the most widely using technology for improvement of Korean Native Cow (Hanwoo) embryo production. However, it is time consuming, required at least 15~20 years to make more than 6 generations, and their offspring number is limited. To overcome such limitations, superovulation and in vitro fertilization have been developed. For superovulation, the number of produced embryos are not enough for commercialization and donor cows need rest period. This led to use of slaughterhouse ovary for in vitro fertilization, but it is impossible to repeat the collection from the same individual and it only can improve the genetic merits of offspring for one generation. Production of embryos using Ovum Pick-Up (OPU) technique, where oocytes can be repeatedly collected from living elite donor, might overcome these limitations. In this study, we investigated the possibility of using OPU technique from donors at different age and different session periods for mass-embryo-production. Oocytes were collected from 26 donor cows twice per week, 3 - 4 months per year, between 2013 and 2016. Results showed that, the average number of embryo produced in first year used donor was significantly higher than that in second year used donor ($3.89{\pm}2.85$ vs $3.29{\pm}2.70$), however, there was no significant difference between third year used donor ($3.51{\pm}3.32$) and other groups. Taken together, our data showed that repeated using of donor up to three years is possible for in vitro embryo mass-production. Moreover, OPU can be used as suitable embryo producing technique for livestock breed improvement.

본 연구에서는 상장기업을 대상으로 하여 감사인의 감사품질이 회계발생액에 영향을 미치는지에 대해 실증적으로 분석하였다. 기업의 회계발생액은 경영자의 재량권을 내포하거나 재무보고의 수단으로 사용될 수 있으므로 회계발생액이 높은 기업일수록 기업성과와 정보비대칭 정도가 높아진다고 볼 수 있다. 대규모 기업일수록 자본시장으로부터의 감시정도가 상대적으로 높기 때문에 경영자가 이익을 성공적으로 조작할 기회가 작다고 보도된 바 있다. 이를 근거로 본 연구에서는 주식시장에 상장되어 있는 상장기업을 대상으로 하여 외부감사인의 감사풍질과 이익조정의 관련성에 관하여 실증분석을 통해 알아보고자 한다. 연구결과, 단일변량분석과 다변량분석을 통해서 Big6와 Non -Big6 간의 감사품질의 차이가 있다고 볼 수 있었다. 이는 여러 선행연구와는 일치하지 않는 결과로서 미국과 우리나라의 주식상장 시장상황의 차이에 기인된 결과라고도 볼 수 있다. The purpose of this study is to investigate the relationship between audit quality and firms' accounting accruals. The firm's accounting accruals involves manager's discretion or used by means of financial information. So we can suppose that high firm's accruals leads high results of earnings and different accounting information between the issuer and the investors. Generally, there is the more monitoring in the market if it is more big firm than smaller. Therefore as previously reported the manager have less chance look out for the firm's interests successfully. We use the sample that consists of 159 firms between 1988 and 2006. The dependent variable of the research model is discretionary accruals estimated by the modified Jones model. According to our results, audit quality are significantly associated with the accounting accruals between Big6 and Non-Big6.
