A study of 426 rabbits from 3 cities in Jilin province (Changchun City and Jilin City) and Liaoning province (Shenyang City) was conducted between May and June 2015. The overall prevalence of E. bieneusi in rabbits was 0.94% (4/426), with 0% (0/116), 1.72% (3/174), and 0.74% (1/136) in Jilin, Changchun, and Shenyang City, respectively. Only 3 farms (farm 1 and farm 3 in Changchun City, farm 8 in Shenyang City) were PCR-positive for E. bieneusi. Moreover, rabbits of more than 6 months (1.72%) had the highest E. bieneusi prevalence, followed by rabbits of 4-6 months (1.26%), 2-3 months (0.58%), and less than 1 month (0%). Analysis of ITS gene of E. bieneusi suggested that all 4 E. bieneusi isolates were genotype D, and were classified as group 1a. The present results first demonstrated the existence of zoonotic E. bieneusi in domestic rabbits in China. Effective control measures should be implemented to prevent E. bieneusi infection in domestic rabbits, other animals, and humans.

Recently it is trend to increase wood use as carbon neutral materials, there is recognized to need necessarily durability improvement of wooden building. It is very rare to report existing on the identification of isolates causing discoloration in domestic weathered wooden building used for long period. The objective of this study was identification of fungi that cause discoloration on the exteriors of weathered domestic wooden buildings in the southern part of South Korea. Our findings can be helpful to establish protection technology for weather deterioration of domestic wooden buildings. Wood chip samples presumed to be contaminated with sapstain fungi were collected from the surface of wooden members used in wooden buildings at Jangheung, Jeollanam-do (two locations, #13 and #14), and Jeju Island (two locations, #31 and #33). The growth of microorganisms was confirmed by performing culture tests for the collected samples, and fungi were isolated, purified, and identified. The results indicated that the fungal strains isolated from wooden buildings #13 and #14 at Jangheung, Jeollanam-do, were 99.83% and 100% homologous to Aureobasidium melanogenum, respectively. For wooden building #31 at Jeju Island (two locations), the fungal strain isolated was 100% homologous to A. melanogenum, which is the same species isolated from the wooden buildings at Jangheung. The fungal strain isolated from wooden building #33 (Jeju Island) had 99.83% homology with A. pullulans, which is commonly found in wood degraded by weather or ultraviolet rays. Our findings can be utilized as a basis for establishing protection technology in domestic wooden buildings.

Modern military operations rely heavily on broadband communication and data transmission. Recently, the rising use of intelligent unmanned technology necessitates more frequencies. Free-space optical(FSO) communication can offer high-data-rate communications with high security and no need for licensing. Therefore, the FSO communication holds significant interest and potential in the defense industry. In this paper, we present design of a FSO communication terminal taking Korean domestic weather conditions into account. The domestic atmospheric attenuation is analyzed using several models and two-year meteorological information for a city in Korea, and this analysis is utilized to design the FSO communication terminal. The design results were verified using an FSO communication test bed, and we achieved an Ethernet bandwidth of approximately 1.86 Gbps at a distance of 1.3 km with the optical amplifier output power of the test bed set to about 20 dBm.

국내 시장에 유통 중인 국내 및 수입산 냉장$\cdot$냉동 삼겹살의 관능적 품질 특성을 조사하기 위하여 총 12종의 수입산 및 국내산 삼겹살을 구입, 연령 및 성별로 구분된 60명의 관능 검사 요원을 대상으로 조사하고 분석하였다. 냉동 삼겹살의 경우, 풍미, 맛 및 연도에서는 처리구별 유의적인 차이를 나타내지 않았으나, 다즙성 및 기호도에서는 국내산 냉동 삼겹살에 비해 수입산 냉동 삼겹살을 더욱 선호하였으며 (p<0.001) 특히, 북미산 냉동 삼겹살에 대한 기호도가 높은 것으로 조사되었다. 또한, 연령에 따른 조사 결과 역시, 국내산보다는 수입산 냉동 삼겹살에 대한 선호도가 높은 것으로 조사되었다. 국내산 냉장 삼겹살과 수입산 냉동 삼겹살의 검사결과의 경우, 국내산 D산의 냉장 삼겹살보다는 수입산 냉동 삼겹살을 더욱 선호하는 경향을 나타내었다(p<0.05). 그러나 국내산C사의 경우에는 기호도면에서 북미산과는 유의적인 차이를 나타내지 않았으나(p>0.05), EU산보다는 높은 기호도를 나타내는 것으로 조사되었다(p<0.05). 또한, 연령에 따른 조사 결과에 의하면 20대의 경우에는 국내산 C사의 냉장 삼겹살을, 30, 40대의 경우에는 북미산 냉동 삼겹살에 대한 선호도가 높은 것으로 조사되었다.

Purpose - Research on the ability of domestic public institutions to conduct business is being conducted. Research on government support policy for public technology projects, emphasizes technology creation. Public agencies are encouraging evolutionary barriers at the stage of realistic business. This paper presents the policy possibilities by presenting policies and strategies based on corporate public policy. Research design, data, and methodology - In this study, we surveyed the actual state of public technology commercialization based on the data on state of technology commercialization of public institutions. We collected and analyzed the literature data to enhance the competitiveness of technology commercialization by identifying success cases of public technology commercialization. In Korea, there are not many research papers that provide policy alternatives for technical commercialization of public research institutes. Therefore, in this paper, we review various government policies and check the status of technology commercialization to increase its value. Results - As a result of this study, it is suggested that various policy development is necessary for the commercialization of public technology, because it is important to increase the value of technology users, suppliers, investors and customers through various network activation. In particular, it is necessary to establish differentiated Korean public technology commercialization model for the proliferation of public technology commercialization by presenting methodical model of technical commercialization.

Korea successfully achieved energy independence in the shortest period of time from being the poorest country in terms of energy 50 years ago through steady development of nuclear technology. In the past, the nuclear industry has been driven through government-centered policy development, public institution-based research, and industrial facility and infrastructure construction. Consequently, South Korea became a nuclear energy powerhouse exporting nuclear power plants to the UAE, surpassing the level of domestic technological independence. However, in recent years, the nuclear industry in Korea has experienced a decline in new plant construction since the Fukushima accident in Japan, which caused changes in public perspectives regarding nuclear power plant operation, more stringent safety standards on the operation of nuclear power plants, and a shift in governmental energy policy. These changes are expected to change the domestic nuclear industry ecosystem. Therefore, in this study, we investigate the priority of technology development investment from the perspective of experts in private nuclear power companies, shifting the focus from government-led nuclear R&D policies. To establish a direction in nuclear technology development, a survey was conducted by applying an analytic hierarchy analysis to experts who have worked in nuclear power plants for more than 15 years. The analysis items of focus were the 3 attributes of strategic importance, urgency, and business feasibility of four major fields related to nuclear energy: nuclear safety, decommissioning, radioactive waste management, and strengthening industrial competitiveness.

국내 섬유산업은 디자인, 브랜드, 인지도 등에서는 선진국에 비해 떨어지고 있고, 중 저가 제품에서는 개발도상국에 비해 경쟁력이 떨어지는 상황이다. 또한 섬유산업 시장은 공급자 중심의 시장에서 소비자 중심의 시장으로 변하고 있다. 최근 이러한 환경변화에 대응하기 위한 핵심기술로 RFID가 주목받고 있다. RFID는 라디오 전파를 활용하여 인지된 사물 간 정보를 교환하는데 이용되는 기술로써 사물을 인식, 추적 그리고 식별을 가능하게 한다. 본 연구에서는 국내 섬유산업의 특징 및 현황과 RFID의 최신 기술동향을 검토하였다. 또한 국내 및 국외 섬유산업의 RFID 적용 사례를 분석하여 섬유산업의 RFID기술 적용 방안을 제시하였다.

본 연구에서는 국내 육종 양파[황색(맵시황, 신선황, 연신황, 영보황, 영풍황), 적색(엄지나라), 연녹색(스위트그린)]와 외국 육종 양파(황색, 선파워; 적색, 천주적) 간의 일반형질, 주요성분 및 항산화능을 비교하였다. 그 결과, 각 페놀성 화합물과 flavonoid의 성분별 총 함량 및 총 페놀성 화합물과 총 flavonoid 함량에 있어 외래품종인 썬파워를 포함한 6종의 황색양파들 중 영보황이 가장 우수한 값을 보였으며, 적색품종에 있어서는 천주적이 엄지나라보다 약간 높은 함량을 보였다. 총 anthocyan의 함량은 엄지나라가 천주적보다 낮았다. 반면 thiosulfate의 함량은 모든 품종들에 있어 유의차를 보이지 않았으며, pyruvic acid 함량은 황색양파들 중 영보황과 썬파워가 동일한 정도로 가장 높았고, 적색품종에 있어서는 엄지나라가 천주적보다 더 높은 함량을 보였다. 그러나 총 당함량에 있어서는 영신황이 썬파워를 제외한 모든 품종들 중 가장 높은 값을 보였다. 그리고 항산화능은 모든 평가항목에 있어 공통적으로 적색품종이 가장 우수하였으며, 환원력에 있어서는 천주적이 엄지나라보다 우수하였으나 DPPH radical scavenging 활성은 천주적보다 엄지나라가 다소 높은 경향을 보였고, ABTS⁺ radical scavenging 활성은 두 품종들 간에 유의차를 보이지 않았다. 황색품종들에 있어서는 신선황과 영보황이 우수한 DPPH radical scavenging 활성을 보였으며, 환원력은 국내산 품종들이 썬파워보다 약간 높은 경향을 보였고, ABTS⁺ radical scavenging 활성은 영신황이 썬파워보다 높았다. 이상의 결과로부터 국내 육성 품종인 영보황과 엄지나라의 성분학적 및 기능학적 우수성이 부분적으로 제시되어진 바, 본 연구결과가 국산 양파 품종의 우수성 홍보를 위한 유용 자료로 활용되기를 기대한다.
