본 논문은 국산 배와 일본산 배에 대한 국내소비자의 무차별 선호를 가정한 가격격차 방법론을 적용하여 일본산 배의 수입금지 조치 해제 시 경제적 · 정량적 영향을 사전에 분석하는 방법론을 소개한다. 방법론을 이용하여 2018년 일본산 배의 수입허용 가정 시 시뮬레이션을 수행한 결과, 연평균 5만 톤의 일본산 배가 국내시장에 유입될 것으로 추정된다. 이 수입량은 국내 배 가격하락 뿐만 아니라 국산 배 생산량 감소를 야기하여 국내 배 생산 감소효과를 초래하여, 연평균 930억원 수준의 직접적인 피해가 예상된다. 국내 배 재배면적과 생산량은 베이스라인 대비 0.7%, 1.4% 감소할 것으로 예측된다. 또한, 생산 · 소비 대체재를 포함한 다른 품목 부문에 미치는 간접적인 영향을 합한 전체 농업분야의 연평균 감소액은 약 2,090억 원 수준으로 베이스라인 대비 0.4% 감소할 것으로 전망된다. 본 연구에서 제안한 SPS 수입금지 조치 해제 시나리오 영향평가는 기존에 수행해오던 양허안 중심의 시나리오 분석과 병행하여, 메가 FTA 참여 시 농업분야 파급영향의 사전분석 방법론을 개선할 것으로 기대된다. This paper proposed a methodology to analyze the economic and quantitative effects of lifting the import ban on Japanese pears by applying a price gap approach in the absence of any preference for either type of pear. Assuming that Korea will allow Japanese pear imports in 2018, the simulation results show that an annual average of 50,000 tons will flow into the domestic market from Japan. These imports will cause a decrease in the price and production of domestic pears, which would have a direct effect on the domestic pear industry, leading to an annual average reduction of 93 billion won. The cultivation area and production quantity are projected to be decreased by 0.7% and 1.4%, respectively, compared to the baseline. Also, the annual average reduction in the overall agriculture sector is predicted to be about 209 billion won, which is a 0.4% reduction compared to the baseline. This research is expected to improve the methodologies available for proactive analysis, with the existing analysis focused on customs tariffs when Korea considers joining mega-FTAs.

In this study investigated the effect of the chemical injection ratio on the drying rate of sewage sludge. Then the economic efficiency was evaluated by comparing the results of the NIR(near infrared ray) and microwave drying rate test. The near infrared ray device showed drying speed of 31.9 %, 28.1 %, and 27.1 % at polymer dose ratio of 8 %, 10 %, and 12 %, respectively. Compared to 8 % polymer dose ratio, polymer dose ratio of 10 % and 12 % showed differences of 8.0 % and 13.6 % respectively, suggesting that drying efficiency decreased as polymer dose ratio increased. The microwave device showed drying speed of 26.2 %, 24.3 %, 21.3 % at polymer dose ratio of 8 %, 10 %, and 12 %, respectively. Compared to 8 % polymer dose ratio, polymer dose ratio of 10 % and 12 % showed differences of 5.2 % and 13.4 % respectively, suggesting that drying efficiency decreased as polymer dose ratio increased. Drying evaluation estimated the treatment cost of near infrared ray device at optimal dose ratio(6 %) was 35,591 won/ton while that of actual dose ratio(8 %) was 38,928 won/ton. Drying evaluation estimated treatment cost of microwave device at optimal polymer dose ratio(6 %) and at 8 % to be 16,683 won/ton and 18,352 won/ton, respectively.

In each experimental unit with 5, 50㎍/g diet concentrations, every individuals of them differentiated to males. About the experimental unit of tributyltin, the females were 100%, 100%, 100%, 100% and 100% in 0.05㎍/g, 0.5,㎍/g, 5㎍/g and 50㎍/g diet concentrations, respectively. About the experimental unit of 2,4-dinitrophenol, the males were 100% tn 0.05, 0.5, 5, 50㎍/g diet concentrations, respectively.

InGaAs 와 InAlAs의 에너지 갭과 광발광 특성

한원석,오병성 충남대학교 기초과학연구소 1997 忠南科學硏究誌 Vol.24 No.1

The optical properties of InGaAs/InP and InAlAs/InP grown by MOCVD have been presented. The energy gap of InGaAs/InP epilayers was found to depend on the strain due to the lattice mismatch, which should be considered for the optical characteristics. From the PL data for a lattice-matched InAlAs/InP epilayer, Varshni equation may be the best expression for the temperature dependence of the energy gap, which was found to be E_g(T) = 1.549-3.16×10^(-4)T^2/(T + 162). The FWHM of the photoluminescence spectra was found to be related to lattice-vibrations. The temperature dependence of the photoluminescence emission could be characterized by two non-radiative recombination processes.

CMOS 연산 증폭기의 고장검출

한석붕,윤원효 慶尙大學校生産技術硏究所 1998 生産技術硏究所論文集 Vol.14 No.-

In this paper, a novel test method is proposed to detect hard and soft faults in CMOS operational amplifiers. Proposed test method makes use of the offset voltage, which is one of the op-amps specifications. During the test mode, CUT is implemented to unit gain op-amps with feedback loop. When the input is grounded, a good circuit has a small offset voltage, but a faulty circuit has a large offset voltage exceeding predefined range of tolerance. Using the proposed method, no test vector is required to be applied. Therefore the test vector generation problem is eliminated and the test time is reduced. The accuracy and effectiveness of the method is verified through HSPICE simulation.

For this study, potato starch, an easily accessible ingredient, was used to make the traditional pressed sweet, dasik, with honey, sirup and fructooligosaccharides as the binding material and green tea powder added to create“ green tea dasik.”Green tea dasik were then examined on their qualities such as sugar content, moisture, Aw, pH, color and mechanical measurements and the sensory acceptability was evaluated. To improve the texture of green tea dasik with 8% green tea powder, honey and fructooligosaccharides were respectively used in place of sirup as the binding material. As a result, the sugar content was the highest when honey was used, but it was also higher with fractooligosaccharides than with sirup. The moisture content was the highest with honey; Aw was the lowest with fractooligosaccharides; and pH was the highest with sirup. The chromaticity test results showed that the L value was the lowest with honey, revealing dark colors. Dasik with fractooligosaccharides showed the brightest colors. As for the a value, dasik using honey, sirup and oligosaccharide showed -5.93, -2.64 and -8.85, respectively. The b value for yellow chromaticity was the highest with fractooligosaccharides. The mechanical measurement test results showed that dasik with fructooligosaccharides have the highest values in elasticity, cohesiveness, chewiness and gumminess. In the sensory acceptability test, the scores for dasik with honey were high in color, sweetness and moistness while the scores for dasik with fructooligosaccharides were the highest in adhesiveness, chewiness, hardness and overall acceptability. As a result of investigating the characteristics in the making of green tea dasik, fructooligosaccharides are evaluated highly as a possible ingredient of dasik.

이원채,장윤환,김효진,이석종,정상립,이수경,배한익 대한피부과학회 2003 대한피부과학회지 Vol.41 No.8

Glomus tumor is a benign lesion characterized by vessels and glomus cells in the varying proportion and it classically presents as a solitary, painful papule or nodule. Occasionally it displays unusual histopathologic features diagnosed as "atypical" glomus tumor, including malignant glomus tumor, glomus tumor of uncertain malignant potential, glomangiomatosis, and symplastic glomus tumor. Glomangiomatosis and symplastic glomus tumor reveal benign biologic behavior. We report herein a typical case of symplastic glomus tumor showing marked nuclear atypia, its only unusual feature comparing with classical one, in addition to the typical clinical and pathological features.
