정보에 대한 정량적 평가방법으로 조건부 가치평가방법을 응용하여 정량화 하였다. 조건부 가치평가 법은 간단히 말해 직접적으로 사람들에게 비시장 재화에 대해 어느 정도 지불의사가 있는가를 설문지를 통해 사용자들에게 직접 묻는 것이다. 기존의 가치평가 법은 해당 정보 재화와 유사한 재화의 시장수요를 추정하여 평가하는 간접적 가치 평가법이 널리 사용되어 왔다. 그러나 정보는 유사한 재화의 명확한 정의가 곤란하므로 이러한 요인들을 고려하여 설문조사를 통한 정보의 가치평가 방법을 선택하여 정보제공 웹 사이트의 경영성과를 측정하였다.

Benomyl, one of the known endocrine disrupting chemicals, was analyzed to understand the its fate in water. Benomyl analysis process in water sample include the following sequential steps. Hydrolysis of benomyl into carbendazim, solvent extraction, concentration, and the concentration of final carbendazim solution was determined by LC/MS (TOF). Recoveries of the spiked samples were good with the range of 80.6 to 118.6% and the MDL was 1,600 times lower than that of LC/UVD method. The use of LC/MS (TOF) successfully eliminated the positive error incurred by interferencing materials in the matrix.

The value of the cell enzyme-linked immunosorbent assay as a possible replacement for the indirect immunofluorescence antibody test for the estimation of antibodies against BD virus was assessed in four animal models. The serum antibody response was measured by both assay systems;the variability of both tests was less than one diluent step, and correlation of the two tests was assessed using regression analysis. The study showed that the all four animal models gave satisfactory correlation of CELISA and IFA. There, CELISA is acceptable for use in mouse, rabbit, chicken and rat models.

Anthropometric data of the hand is one of the important issues for the product design related with hand and manual operation in terms of user-centered design. Direct measurement, which traditionally uses anthropometric measuring tool, has a few disadvantages in cumulation of measuring time, possible errors in raw data, doubtful reliability between inspectors. Newly introduced 3D scanning technology overcomes those disadvantages; however, another disadvantages, such as, hight cost and immovability, have been introduced. In this study, photogrammetric approach was introduced for the measurement of anthropometric data in hand. In order to minimize the possibility of error during direct and indirect measurement, a simulated object was used and effectiveness of photogrametric measurement was confirmed for the collection of anthropometric data in hand.

The exploration of the interaction effect among the components of attractiveness is impossible; therefore, this study uses an indirect estimates approach with multiple scale items that can measure the interaction effect among the components of attractiveness to solve the problem of direct estimates. Previous studies focused on intra-store type competition as their subjects; subsequently, this study dealt with intra-store type competition as well as inter-store type competition in the competing and selecting activities among fashion retailing stores with different business models (such as department stores, road brand stores, discount stores, outlets and internet shopping malls). This study suggests a generalized model for shopping attractiveness of stores and proposes a fashion retailing store type attractiveness (FaRSTA) model instead of a simple relative importance between store selection standards.

This study was to build the database by collecting the results of legal leak test and self-test conducted by the owners of soil contamination facilities at soil-related specialized agency to grip objective status on soil contamination facilities and evaluate classification results. The results of the study showed that the unsuitable rate of business unit is 53.6%, the business with leak that could cause actual pollution is 25.7%, the unsuitable rate of the voluntary self-test is 57.3%, that of the compulsory inspection is 17.2% depending on the test motivation, that of the direct-test is 58.9%, and that of the indirect-test is 22.5% depending on the test methods. There was a significant difference between the test motivation conducted and the test methods applied. From the results of the unsuitable reasons obtained we could assume that about 20% of the whole target tanks became potential sources with natural defects occurred when such tanks were made, and 2.2% of the whole tankers examined that persisting period was caused by progressing corrosion below the minimum thickness.

물발자국은 국가별 실제 물소비량을 파악하고 물 부족 상황에 효율적으로 대비하기 위하여 도입된 지표로서, 제품의 생산과 서비스 전 과정에서 직접 및 간접적으로 사용되는 물의 총량을 의미한다. 선진국에서는 물 사용 패턴에 대한 인식을 제고하고자 국가, 도시, 산업분야 등 다양한 물발자국 데이터베이스를 구축하여 활용하고 있다. 그러나 우리나라의 경우, 물 수입 의존도가 높지만 물발자국 산정에 대한 연구가 부족하여 효율적인 물 관리 및 안정적인 수자원 확보를 위한 국가전략 수립에 어려움을 겪고 있다. 물발자국 산정 연구는 국가적 차원의 정확한 물 수지 계산과 수자원계획 수립에 유용한 기초자료로서 활용이 가능하다. 이에 본 연구에서는 우리나라의 제1차 및 제2차 산업의 물발자국을 산정하였으며, 산정 방법으로는 상향식 접근법과 하향식 접근법을 적용하였다. 제1차 산업의 농업계 및 축산업계의 물발자국은 단위 물발자국에 기초한 상향식 접근법과 용수사용량에 기초한 하향식 접근법을 적용하여 산정하였다. 산업별 물발자국 산정결과는 다음과 같다. 주요 농작물 생산량 및 작물 품목별 단위 물발자국을 이용한 국내 농업계 물발자국 산정 결과, 1980년부터 2014년까지의 쌀 외 18개 농작물에서 연간 78억~109억 $m^3$로 산출되었다. 반면 농업용수 사용량에 기초한 하향식 접근법을 통해 산정한 농업계 물발자국은 118억 $m^3$으로 분석되었다. 다음으로 제1차 산업의 축산업계 물발자국을 산정하였다. 2011년부터 2015년까지 주요 가축 사육두수와 지육량, 사료작물의 단위 물발자국을 활용한 축산업계 물발자국은 평균 73억 $m^3$, 축산용수사용량을 활용한 물발자국은 평균 309억 $m^3$으로 나타났다. 축산용수사용량에 기초한 분석결과가 크게 나타난 것은 축산업분야에서 간접수의 비율이 높기 때문이다. 한편 제2차 산업의 공업계는 제품생산 공정의 물 사용량, 부품 및 원료의 단위 물발자국 등 세부사항의 파악이 곤란하여 하향식 접근법을 적용하였다. 공업용수 사용량과 공업용수 오염물질의 배출부하량에 따른 물발자국 산정 결과, 연간 26억 $m^3$으로 분석되었다. 이와 같은 산업별 물발자국 산정결과를 활용하여 산업별로 차별화되는 물 이용 패턴을 분석하고 산업별 용수 수요를 파악하면 국가적으로 효율적인 수자원 관리방안을 제시할 수 있다.

The applicability of indirect immunoftuorescent antibody test (IFAT) was compared with enzyme-linked immunosorbent assay (ELISA) in sera from 163 cases of confirmed neurocysticercosis, 101 other neurologic and parasitic diseases and 100 normal controls. As antigen, frozen sections of a Taenia solium metacestode from a human brain was used in IFAT and cystic fluid was used in ELISA. For the detection of specific IgG antibody, IFAT was equally sensitive (89.6%) and specific (85.1%) as ELISA. The antibody titers by IFAT were correspondingly increased with mean absorbance of ELISA. The corresponding rate of positivity in the two techniques was 90.8%. Except for the difficulty in detecting antibodies in cerebrospinal fluid (CSF), IFAT was concluded to be very useful for the serodiagnosis of human neurocysticercosis.

In order to develop an enzyme-linked immunosorbent assay(ELISA) for detecting aflatoxin $B_1(AFB_1)$, we produced and purified antibodies, thereafter established and evaluated methods of direct and indirect competitive ELISA. Anti-AFB, antisera, produced by immunizing rabbits with $AFB_1$-1-(0-carboxymethy1)oxime-bovine serum albumin conjugate ($AFB_1$-BSA), were removed of anti-BSA antibodies by quantitative precipitation reaction and further purified by ammonium sulfate precipitation and DEAE-Sephadex A-50 ion exchange chromatography. Purified IgG fractions were used as anti-$AFB_1$ antibodies. The antibodies, whose titer was deterrnined extremely high above $2 \times 10^6$, showed low cross-reactivity of 3~34% against $AFB_1$ analogues such as G2, B2, and GI. From the standard curves of direct and indirect competitive ELISA for AFBI, the detection ranges were found 0.2~20 and 1~10, 000 ng/ml(ppb) respectively. In their sensitivity, stability, simplicity, and rapidity, the direct method was more suitable than the indirect method for practical use.
