고분자 분리막을 이용한 이산화탄소 포집공정은 최근들어 분리막 소재기술의 발전과 함께 관심이 급격하게 높아지고 있다. 미국의 경우는 MTR사가 DOE의 지원을 받아 1MWe 규모의 발전소 배가스 중의 이산화탄소를 포집하는 실증연구를 진행하고 있다. 또한 유럽에서는 노르웨이의 NTNU가 미국 Airproducts사와 협력하여 시멘트제조공정에서 발생하는 이산화탄소를 포집하는 연구를 수행하는 중이다. 본 연구는 (주)에어레인이 미래부산하 KCRC 센터의 지원을 받아 50 Nm3/hr 규모의 배가스를 처리하는 단위 모듈을 이용하여 150 Nm3/hr 규모연소배가스 포집공정을 설계하는 과정을 언급하고자 한다. 또한 이 플랜트의 시운전 과정에서 얻어진 데이터와 공급기체중의 산소농도의 영향등이 다뤄질 것이다. 최종적인 주요결과는 CO2 회수율 93%, 회수농도 85%이었다.

This study investigates dynamic characteristics of a 2MW wind turbine structure by long-term response monitoring with accelerometers, tiltmeter and strain gauges. The object wind turbine structure is located in Jeju Island, Korea. The natural frequency and damping ratio were evaluated by least-square frequency domain decomposition and random decrement technique using acceleration response data. As a result, it was found that natural frequencies with 1st, 2nd and 3rd modes, and blade passing frequencies with 1P, 2P and 3P were clearly showed from power spectral densities of acceleration reponses. Furthermore, 1st model frequencies were almost constant with increase in standard deviations of acceleration responses. Another notable observation was that when standard deviations of acceleration responses were small, damping ratios showed to diverge. However, when standard deviations of acceleration responses had large values, damping ratios were converged to about 0.5%.

In order to distribute agricultural robots to the fields, based on the review of Japanese trends, three preliminary tasks and implications for the development of agricultural robots in Korea are derived as followings. The first result is that farmers are small-scale, agricultural robot is necessary to standardize through the public-private partnerships and reduce the supply price through the utilization of existing technologies and components. Secondly, the car-based robots are GPS-based system, and it is necessary to construct a nation-wide regional base stations that can trensmit the GPS correction signals free of charge in real time. Third, additional research is needed to cope with the unexpected situation in the fields, such as obstacle avoidance technology, robot safety evaluation technology, and safety standard development. In addition, although agricultural robots are being developed in Korea, a step-by-step approach is necessary for solving the above-mentioned pre-requisites for field distribution. In the first stage, it is necessary to supply an autonomous straight guidance system that assists the worker. The second stage is the spread of cooperation system between human and robot. The third stage is a complete robot system, in which the robot works on its own. Therefore, the supply of agricultural robots needs to be approached sequentially.

We have constructed a wide-field photometric survey system called as the Korea Microlensing Telescope Network (KMTNet) in 2015. It consists of three 1.6 m optical telescopes equipped with mosaic CCD cameras. Four 9k CCDs were installed on the focal plane of each telescope. In this paper, we present the crosstalk analysis of the KMTNet mosaic CCD images. The crosstalk victims caused by bright sources were visible at eight sub-images obtained through different readout ports of each CCD. The crosstalk coefficients were estimated to be several tens of 10-4 in maximum, differing from sub-image to sub-image, and the non-linearity effect certainly appeared at the victims made from saturated sources. We developed software functions to correct the crosstalk effect of the KMTNet CCD images. The software functions showed satisfying results to remove clearly most of the crosstalk victims and have been implemented in the KMTNet image processing pipeline since 2015 September.

Asparagus cochinchinensis is known to ameliorate respiratory disease. We evaluated the antimicrobial activity of non-fermented and fermented A. cochinchinensis using lactic acid bacteria and investigated the physicochemical characteristics of the fermented A.cochinchinensis. Non-fermented A.cochinchinensis showed lower levels of antimicrobial activity than the fermented A.cochinchinensis. Ethyl acetate (EtOAc) extracts of the fermented A. cochinchinensis showed antimicrobial activities against the indicator strains at lower minimum inhibitory concentration (MIC). The MIC of the EtOAc extract of non-fermented A. cochinchinensis against Escherichia coli, Staphylococcus epidermidis, and Stphylococcus aureus were 100, 75, and 100 mg/ml. In contrast, the MIC of the EtOAc extract of ACLM was 25 mg/mL against E. coli. The MIC of the EtOAc extract of ACLS was 12.5 mg/mL against S.epidermidis, and the MIC of the EtOAc extract ofACLP was 12.5 mg/mL against S.aureus. The viable cell number, pH, and acidity of A. cochinchinensis fermented by Lactobacillussakei 383 were similar to those of A. cochinchinensis fermented by Leuconostocmesenteroides 4395, but were different from those of A. cochinchinensis fermented by Lactobacillus.plantarum KCCM 11322. These results suggested that the fermented A. cochinchinensis by lactic acid bacteria may be a good candidate for application to ameliorate respiratory disease.

우리나라의 시설원예 산업은 농업용 필름이 생산되고 보급되면서 우리나라의 시설원예는 급속도로 발 전하였다. 그 후에 골조는 아연도금 파이프, 피복재는 연질필름을 이용하여 보온재배 위주의 시설이 전 국적으로 설치되었다. 바이오가스에 포함된 황화수소 및 메탄은 온실 자재나 작물에 악영향을 유발하는 요소로 작용될 수 있다. 그리하여 본 연구에서는 유기성폐기물인 바이오가스에서 막 분리법을 이용하여 CO2 가스를 정제, 포집하였다. 그리고 정제된 CO2를 온실에 공급하여 바이오가스에 포함된 성분들이 온실의 자재에 미치는 영향을 분석하였다. 실험은 세가지 실험구를 설정하여 시행하였으며, 실험 1은 일반적으로 온실 시용에 판매되고 있는 온실용 액화 CO2를 시비한 경우(온실-1), 실험 2는 바이오가스 에서 분리한 CO2를 시비한 경우(온실-2), 실험 3은 CO2를 공급하지 않은 일반적인 경우인 대조구로 실 험을 행하였다. 실험 결과, 시중에는 판매되고 있는 CO2를 시비한 온실과 대조 실험구와 비교하였을 때, 피복자재의 투과도, 인장강도는 세 실험구에서 모두 유사하게 측정되었다. SEM, EDS 분석 결과, 세 실험구에서 산화철의 결정이 나타났으며, 파이프 자재 표면의 O와 S의 함유량은 두 번째 온실에서 높게 나타났다.

The Agriculture, Forestry and Fisheries Research Council within the Ministry of Agriculture, Forestry and Fisheries looks over the Agriculture, Forestry, and Fisheries Research and Development Project. Every five years, it revises the Agriculture, Forestry and Fisheries Research Basic Plan. Based on the information above, the following suggestions are made to implement domestic research projects. First, the strategic planning and promotion of research and development projects are needed to achieve the goals of the country and agricultural policy. Second, it is necessary to break up and diversify research assignments so that the project implementation reflects the trend of the time. Third, there is a need to develop a research partnership that strengthens cooperation among industry, academia, government, and research institutes to utilize technology seeds from fields other than agriculture. Fourth, it is necessary to improve field demonstration research projects where central and local research institutes, universities, private companies, agricultural cooperation, and farmers can participate. Fifth, follow-ups should be conducted at the end of research to advance research implementation systems. Finally, there is a need to build a new dissemination system which includes research results and policy.

2015년 12월 한국과 중국간의 자유무역협정(Free Trade Agreement) 이 발효되었다. 중국은 2015년 7월 현재 우리나라의 제1의 수출국이면 서, 제2의 수입국으로 전체 교역국 중 1위를 차지하고 있는 우리나라의 최대 무역대상국이다. 중국과의 교역이 늘어날수록 우리나라의 지식재산 권을 침해하는 물품의 수출입도 늘어날 가능성이 충분히 존재하고 있으 며 우리나라의 지식재산권을 침해하는 물품이 중국의 세관에서 적발되는 사례도 증가하고 있는 추세이다. 지식재산권의 침해가 의심되는 물품의 국내 유통을 막기 위하여 국경 에서 통관중인 물품을 세관에서 통관을 저지하는 방법인 이른바 국경조 치(Border Measures)를 취하고 있는 나라가 많다. 우리나라의 경우 세 관이 지식재산권을 침해하는 물품을 세관에서 통관보류나 유치할 수 있 는 제도를 시행하고 있으며 그 근거가 되는 법률은 「관세법」이며, 「관세법 시행령」과 「지식재산권보호를 위한 수출입통관사무처리에 관 한 고시」에서 구체적인 절차를 규율하고 있다. 중국의 경우에도 지식재산권을 침해하는 물품을 세관에서 압류할 수 있는 제도를 시행하고 있으며 그 근거가 되는 법규는 《중화인민공화국 지식재산권세관보호조례》와 《중화인민공화국세관의 지식재산권보호조 례에관한실시방법》이다. 세관에 의한 국경조치는 지식재산권을 침해한 물품이 국내에 반입되기 전에 세관에 의해 통관을 저지할 수 있다는 점에서 지식재산권을 효율적 으로 보호할 수 있는 방법의 하나로 판단된다. 중국이 우리나라의 최대 교역대상국이 된 상황에서 중국내에서 제조된 지식재산권침해물품의 국 내유입을 막을 수 있는 효과적인 방법이라 할 것이다. 한국과 중국의 세관에 의한 지식재산권보호제도의 구체적인 절차를 비 교·고찰하고 우리나라의 세관에 의한 지식재산권보호제도의 문제점을 고찰하였다.

Recently, companies and organizations are becoming increasingly dependent on external resources to keep their competitive advantages under the turbulence of global business environmental changes. Therefore, they focus on the paradigm ‘Open Innovation (OI)’ which is reported as a convincing strategy to improve competitive advantage in terms of budget and time-to-market. The management of Incheon International Airport Corporation (IIAC) also considers the introduction of Open Innovation not only to adapt the business environmental changes but also to be devoted its social role as a public corporation. In this paper, we describe how we derived the promotion tasks for the introduction of OI and prioritized the tasks, performing our research on the IIAC Open Innovation. For these purposes, this research conducted the following three steps; the first stage for the analysis of current situation on the IIAC Open Innovation, the second stage for the elicitation of promotion tasks, and the last stage for the prioritization of the promotion tasks. In the first stage, critical success factors (CSFs) for open innovation introduction were derived from different research papers and case studies. In the following stage, promotion tasks were elicited from the IIAC based on the CSFs. In the last stage, the promotion tasks were evaluated on the base of criteria by using Analytic Hierarchy Process (AHP). And then the promotion tasks were grouped by the result of the evaluation. In this case, thirteen promotion tasks were derived for open innovation, ten promotion tasks except three inevitable promotion tasks were evaluated, and then they were grouped into four categories based on the importance-possibility analysis.

가축 사육형태가 규모화 됨에 따라 가축분뇨 발생량은 지속적으로 증가하고 있으며, 가축분뇨를 에 너지로 이용하고자 하는 자원화에 대한 요구가 점차 증가되고 있다. 국내에서 발생하는 가축분뇨 에너 지화의 경제적 효과는 4,777억원으로 기대되고 있다. 따라서, 축산분뇨를 원료로 하는 바이오가스 플 랜트에서 발생하는 가스의 이용에 관한 연구는 활발히 연구되고 있다. 본 연구에서는 가축분뇨를 원료 로 한 바이오가스 플랜트에서 발생하는 가스의 이용에 대한 다양화를 모색하고자, 바이오가스 내 개별 성분의 분리 및 정제 방법을 구명하였다. 그리고 바이오가스 내 대표적인 성분이 CH4, CO2가스의 분 리를 통하여 독립적인 활용 방안을 제시하고자 한다. 이를 위해 발생하는 가스의 분리를 행하였으며, 분리된 가스의 적정 이용을 위한 정밀분석을 하였다. 그 결과, CH4가스는 약 95%, CO2가스는 약 93.2%로 정제되었으며, 분리된 가스 속에는 황화수소의 경우 1ppm이하로 포함되어 있는 것을 확인하 였다. 정제 CO2가스의 정밀 분석 결과, 도시가스 품질 기준표와 비교하였을 때, 정제 CH4에 포함된 성분들이 품질 기준표에 적합한 농도를 나타내었다. 정제 CO2의 정밀 분석 결과, 농업시설 내의 작업 자와 작물에게 유해한 성분들의 함량이 매우 미세하게 나타났다.

가스생산기지의 탱크보수와 가스배관 기밀시험 및 가스치완에 사용되는 질소는 액화질소를 기화시켜 공급하고 있으며, 불활성 가스인 질소의 용도는 천연가스 설비에서 선박용까지 그 사용처가 다양하다. 질소발생기술은 극저온증류식(Cryogenic distillation), 흡착식(Pressure Swing Adsorption), 분리막식(Membrane)이 있으며 극저온증류식은 장치비가 높아 대형플랜트에 적합하고 흡착식 및 분리막식은 중소규모에 적합하다. 특히, 분리막식은 장치가 간단하고 진동에 대한 성능저하가 없어 이동식 질소발생에 적합한 기술이다. 분리막 방식의 이동식 질소발생플랜트의 설계기술은 분리막모듈, 장비, 배관, 전기, 진동, 에너지 관리 등의 최적화를 통해 이루어진다.

Recent growing about global warming has led to increase the need for low-carbon, green growth policy at the agricultural sectors and interest in the environmental-friendly and organic products. Therefore, Korea government has decided to reduce the use of chemical fertilizer at the farm field up to 40% and in order to attain this goal, promoting to grow green manure crops has been taken into positive consideration in terms of maintaining soil fertility and preventing soil loss. To this result, the acreage to cultivate green manure crops has been sharply increased from 4,000ha in 1998 to 225,000ha in 2012. Regarding environment-friendly agriculture, bulk of rice straw should be incorporated into the paddy just after harvest as soil cover materials and also green manure crops, such as chinese milk vetch, rye, Hairy vetch and so on have been recommended to be grown annually as soil cover crops. General sowing process of a certain seed crop at the farm field consists of plowing, harrowing, seeding, covering up seeds with soil in order. This process at the field has been known to take relatively long time and even not to be equal at the seeding depth. For this reasons, new seeding technology has been continuously required by farmers. Partial-tillage seeder consisting of dressing furrow and seeding parts enable to overcome germination barriers. Two soybean cultivars, ‘Taekwang’ and ‘Shingi’ were used to test the performance of newly-developed seeder and its establishment rate showed around 70 ~ 90% with given interval of embedded soybeans. Furthermore, the partial tillage technology applicable to the soybean field could reduce labor cost by 69% as well as 22% of the fuel consumption and also promote soybean productivity per unit area.

This study is about implementing an job matching web service system based on the Job seeker’s company assessment model proposed by the researchers. Basically, the Job seekers’ company assessment model is based on the concept that each job seeker can evaluate the recruitment company candidates using job seekers’s own major consideration factors. Using the implemented information system, each job seeker’s main considerations in job searching process are evaluated and stored and compared to those of other job seekers’ or groups’ characterized by sex, job experience residential area and etc. by finding out and listing up the companies in the order of the preference of job seeker own or belonging groups, job seekers can be helped to find suitable companies which fit well to themselves.

Flaring gas에서 CO2 제거를 위해 폴리술폰 고분자를 이용한 중공사막을 제조하였다. 제조된 중공사막은 1단과 2단 공정의 전산모사와 실제 공정을 통해서 CH4 농도 99% 이상 CO2 농도 1% 미만의 운전조건과 성능을 확인하였다. 또한 25 Nm3/h 급 bench scale CO2 분리막 연속공정에서 100시간의 운전시간 동안 CO2의 농도를 1% 미만으로 안정적으로 운전 하였고 이때의 CH4 회수율은 약 98%였다.

This study is conducted to suggest ways to mitigate the mismatch phenomenon between job seekers who want to find right company for themselves and companies looking for appropriate new employees. For this purpose, this study improves the company assessment framework reflecting job seekers interests by using fuzzy analytic hierarchy process. The improved evaluation framework is a three-level hierarchical structure, where there are 4 groups at the top level, 12 factors at the intermediate level and 36 indexes at the bottom level. For the empirical analysis of the applicants preferences based on the improved model, a survey for F-AHP analysis is carried out to university students and then priorities of components in the evaluation model are calculated. Moreover, the differences of priority of the company assessment framework are analyzed for different genders, college years, and major divisions. The results show that job seekers’ most concerning factors are wages, stability, working environments, and labor deal, which are ranked highly in this order and the differences in preferences for each type of job seekers (genders, college years, and major divisions) are obvious. The results also show that the male prefers wages to environment, on the other hand female does working environment to wages.
