In the current research, a manganese and cobalt oxides-based nanocatalyst was developed which was used to make an efficient cathode electrode for fuel cells. The nano MnOx/ MnCo2O4 was synthesized through a hydrothermal procedure followed by sintering at 500–600 °C. X-ray diffraction and scanning electron microscopy besides electrochemical techniques were applied for the characterization of the synthesized nanocatalyst. The carbon black type Vulcan (XC-72R) and PTFE were used to prepare the active reaction material of the cathode electrode named carbon paste (CP). Loading of the synthesized nano MnOx/ MnCo2O4 on CP was optimized in a weight ratio of 10–90% for the oxygen reduction process in neutral conditions. The best performance was gained for the 50 W% MnOx/ MnCo2O4 loaded CP, whose active surface area was twice the bare CP. The values of the exchange current density of the ORR obtained by electrode containing 50 W% MnOx/ MnCo2O4 was calculated as 0.12 mA/cm2. The low price, good catalytic efficiency, and cyclic stability of the MnOx/ MnCo2O4 nanocatalyst compared to the commercial platinum-based catalysts confirm its ability to develop fuel cell electrodes.

Recently, the government has provided support such as entering new markets, expanding sales channels, and supporting manpower, not just in the form of funding, to efficiently and effectively support limited national resources to improve corporate performance. In this study, we tried to find out the effect of government support for companies that have benefited from the Excellent Technology Research Center Project (ATC Project) and the World Class 300 project using propensity score matching. As a result of the analysis, the effect of government support for the ATC project became visible after the appointment period, while the effect of the World Class 300 project was insignificant. This means that when the size of the company is small, the effect of government support is more pronounced. This suggests that in order to maximize the effectiveness of government support, appropriate national policy interventions such as government innovation funding are needed when the size of the company is small. In this study, differences in the timing, performance indicators, and company size of policy support effects were found in the growth stage of a company from a mid- to long-term time series perspective, suggesting that support policies based on this need to be adjusted and redesigned.

한반도는 중국과 러시아 등 주변국의 잠재적 위협과 북한의 직접적인 안보위협이 상존해 있다. 징병제를 시행하는 한국군은 20세 연령대의 병역 자원 대상자 급감과 병 복무기간 18개월 단축은 초급장교의 73%를 차지하 는 학군사관후보생 지원율 저조로 이어져 우수인력 확보에 어려움이 있다. 따라서 본 연구에서는 우수한 학군사관 후보생을 선발하기 위한 지원자격 보완, 병 복무기간 단축에 따라 징병제에 부합한 초급장교의 복무기간 현 실화, 가산복무 지원금과 단기복무 장려금에 대한 법령개정으로 경제적 혜 택 확대, 병 급여 200만원 시대에 부합한 초급장교의 복지대책 등을 제시 하였다. 우수한 학군사관 후보생 모집하여 4차 산업혁명 시대의 MZ세대를 지휘할 수 있는 능력과 역량을 갖춘 우수한 초급장교를 양성해야 한다. 이 를 통해 소부대의 안정적 관리와 전투력을 창출하여 적의 도발을 억제 및 군사대비태세를 유지하고 전역 후에는 사회의 다양한 영역에서 중추적인 역할을 하도록 해야 한다.

A new strawberry cultivar ‘Misohyang’ was originated from the cross between ‘Darselect’ and ‘Wongyo 3111’ in 2009. Among hybrids, ‘Misohyang’, a superior individual possessing vigorous growth, capacity to early differentiate flower buds, and excellent physiological characteristics, was selected. Several tests conducted from 2012 to 2014 revealed that this cultivar was suitable for forcing culture due to its faster flowering and harvest time than ‘Seolhyang’. Fruits of ‘Misohyang’ were conical in shape with a red color, which turned dark red color when fruits were fully ripened. Although sugar contents in ‘Misohyang’ fruits were lower than those in ‘Seolhyang’, their aromatic properties were excellent in terms of synergy effect on perception of sweet flavor. In addition, ‘Misohyang’ fruits could maintain high hardness despite a warm temperature during spring. These physiological characteristics of fruits contribute to its high yields in spring, with an average fruit weight of 20 g. Regarding disease resistance, ‘Misohyang’ showed sensitivity to powdery mildew during nursery period and fruit ripening stage. Since the cultivar ‘Misohyang’ has an excellent flavor with attractive red color, sustainable hardness, and high yields in spring, it is expected to be popularly consumed not only for its fresh fruits, but also for its processed fruits.

The purpose of this study was to breed a variety of stable productivity and high storage characteristics of white Hypsizygus marmoreus, which has high demand at domestic and global market due to a low bitter taste and the preference for white species. Accordingly, ‘Baekmaru’ was bred by hybridizing brown and white cap color species and backcrossing with white species. The ‘Baekmaru’ variety was bred by crossbreeding the brown and white species and backcrossing the white species. Through repeated cultivation of ‘Baekmaru’, a variety with a low contamination rate was selected when culturing the spawn for stable cultivation. As a results of demonstration test, the yield of ‘Baekmaru’ was 14% higher than that of the commercial variety. In addition, among the fruiting body characteristics of ‘Baekmaru’, diameter and thickness of the pileus were 16.43±15.27mm and 6.46±0.58mm, which were slightly higher than the commercial variety, and the hardness was 2.69±0.89N for the pileus and 3.09±0.89N for the stipe. The shelf life showed less change in thickness and color of pileus compared to commercial variety. The hardness of pileus of 'Baekmaru' was maintained in the range of 3.5 to 4.0N in the 4oC and 4oC and 20oC mixed treatment until 30 days of storage, and was higher than that of the commercial variety. Therefore, it was suggested to be excellent in storability.

연중생산이 가능하고 특히, 저온에서 화색발현이 우수하며 볼륨감 있는 스프레이국화 신품종을 개발하기 위하여 충청남 도농업기술원 화훼연구소에서 2010년에 모본으로 황색의 홑꽃 ‘SP09-251-01’를 부본으로 ‘SP08-010-16’계통을 인공수분 하였다. 종자 파종은 2011년에 실시하였고, 실생개체 중 화색과 화형이 우수한 281번째 개체를 선발하여 ‘SP11-103-05’로 계통명을 부여하였다. 주년생산성 검정을 위하여 2011년부터 2013년까지 자연일장, 전조재배, 차광재배를 각각 실시하였고, ‘Yes Holic’과 화형, 화색, 초형이 비슷한 ‘Jazz’ 품종을 대조품 종으로 사용하였다. ‘Yes Holic’ 품종은 2013년에 국립종자원에 품종보호 출원을 하였다. ‘Yes Holic’은 황색(Yellow 7A)의 꽃잎과 녹색(Green 1B)의 화심색으로 조사되었고 자연일장 작형의 개화기는 10월 25일로 ‘Jazz’의 10월 26일에 비해 빨랐다. ‘Yes Holic’의 초장과 줄기굵기는 각각 80.2cm와 6.1mm 로 ‘Jazz’의 78.6cm와 5.3mm보다 컸다. ‘Yes Holic’의 꽃 직경은 4.4cm로 ‘Jazz’의 4.1cm보다 컸으며, 착화수도 ‘Yes Holic’ 가 29.4개로 ‘Jazz’의 22.1개보다 많았다. 흰녹병저항성은 ‘Yes Holic’이 10%이하의 발병율인 3단계로 흰녹병이 저항성이 높은 것으로 확인되었다. 재배상 유의사항은 ‘Yes Holic’은 소등 후 야간온도를 18℃로 가온하면 고유화색 발현과 적당한 착화수 확보 및 균일한 개화가 가능하다. 그리고 여름철 고온기에는 ‘Yea Holic’의 총포에 잿빛곰팡이병이 주로 발생되므로 스크린과 포그를 활용하여 주간온도를 낮추고 봉오리 착색기에 전용 농약을 살포해 주어야 한다.
