The purpose of this study is to estimate regional economic effects of spatial diffusion of wildfire using Cobb-Douglas production function of agriculture and forestry. The analysis is applied to Gangwon and Gyeongbuk provinces where are the most damaged of wildfire in Korea. The damaged areas are derived from multiplied by the occurrence probability of wildfire and diffusion areas of wildfire for micro-spatial unit level with ArcGIS techniques. The models of wildfire provides that the spatial diffusion of wildfire increases with the rising of highest temperature and average wind speed. Through the production function, value added of Agriculture and Forest sectors get damaged where the Cos-converted slope aspect of mountains are toward the South. The production model provides reductions of regional value added by increasing damaged areas of wildfire. It reveals that the most damaged region is Andong city in Gyeongbuk province, where value added loss is 1.25 billion Won, which is about 0.72% of total value added in agriculture and forestry of the city. As a view of policy makers, it needs to be considered to establish prevention policies against wildfires because regional economic losses from wildfire are depending on geographical conditions and performances of the major industry related to wildfire's diffusion such as agriculture or tourism sector according to the result of analysis.

Until now, research on inter-Korean economic cooperation and economic integration has been limited to the areas of the two Koreas. However, Korea is connected with many countries in Asia through the global value chain. Thus, if inter-Korean trade deepens, it may affect the trade structure of neighboring countries. In order to establish a specific inter-Korean economic integration policy when North Korea becomes a normal state in the future, an analysis that reflects the trade structure including Northeast Asia must be preceded. Therefore, in this paper, the impact of inter-Korean trade on Korea, China and Japan was analyzed using the international input and output table containing actual trade data. The scope of analysis was limited to agriculture, reflecting North Korea's demand for economic cooperation. The results show that trade in the agricultural sector between the two Koreas did not have a significant effect of production and value added. but when China and Japan participate in trade with North Korea, the production effect was calculated to be as high as 4 million dollars in Korea and up to 10 million dollars in Japan. And China showed up to 520 million dollars. In addition, the value-added effect was calculated up to $1 million in Korea, up to $4 million in Japan, and up to $250 million in China.

The purpose of this paper is to decide priorities of policy-objectives and support measures related to the $6^{th}$ industrialization of agriculture, and prepare policy-objectives and alternatives to contribute to maintaining and promoting the community through creation of more jobs and added value. We used the Analytic Hierarchy Process (AHP) to reflect the experts' opinions about objectives, means and priorities of the $6^{th}$ industrialization of agriculture. The important objectives of the 6th industrialization of agriculture were to create jobs, to increase added values, and to maintain and activate the community. The results showed that the most important objectives for the $6^{th}$ industrialization of agriculture were maintaining and activating the community, expanding added values and creating employment in order. Policy means to achieve these objectives were financial support, human resource training & consulting, research & development, and marketing. The decision-makers determined marketing as the most important among the policy means to achieve the objectives of the $6^{th}$ industrialization.

This paper approaches knowledge capital as social infrastructure and analyzes its impact on economic growth. To this end, we constructed a panel dataset for 120 countries for the years 2000-2014 and estimated the economic growth function using the panel analysis. As proxies for knowledge capital, we used the R&D expenditure per capita and the number of patent applications per thousand people in each country, both measured in stock. Economic growth was measured in terms of real GDP per capita and real value added per capita at the industry level. The empirical findings demonstrate that knowledge capital accumulated in a society significantly promotes economic growth. Especially R&D stock increases real value added per capita in all industries-not only manufacturing, but also services and agriculture-implying substantial inter-industry spillover effects. The findings of this study suggest that knowledge capital boosts economic growth as core social infrastructure.

전처리 방법을 달리한 마늘의 항산화 활성을 비교하고자 대두유에 생마늘, 찐마늘 및 흑마늘 분쇄물을 농도별로 가하여 $60^{\circ}C$에 저장하면서 유지의 산패 정도를 비교분석하였다. 저장기간이 경과할수록 유지의 색도가 높아졌으며, anisidine value는 저장 14일에 급격히 증가하여 저장 28일까지 지속적으로 증가하였다. 산가는 생마늘과 찐마늘 첨가구에서는 시료의 첨가 농도 따른 유의적인 차이가 없었으며, 흑마늘의 경우는 저장 14일 이후부터는 시료의 첨가 농도가 증가할수록 산가가 증가하는 경향이었다. 과산화물가는 ${\alpha}$-tocopherol이나 BHT 첨가군에 비하여 마늘 분쇄물 첨가군에서 더 낮아 마늘 분쇄물이 과산화물의 생성을 효과적으로 억제함을 확인할 수 있었다. TBA 값은 저장기간이 경과할수록 증가하였으며, 시료의 첨가 농도가 높을수록 생성억제 효과가 더 컸는데 저장 28일에 대조군(335.63)에 비해 찐마늘 5 g/100 g 농도(336.97)를 제외한 모든 시료의 TBA 값이 더 낮아 TBA 생성억제 효과를 확인할 수 있었으며, 40 g/100 g의 농도에서는 BHT보다 더 효과적으로 산패를 억제함을 확인할 수 있었다.

열풍건조 및 동결건조된 와송의 열수추출물을 대두유 및 돈지에 0.1, 0.5 및 1.0 g/100 mL의 농도로 첨가하고 $180^{\circ}C$에서 가열하는 동안 유지의 산화 안정성을 측정하였다. 유지의 색도는 가열시간이 경과될수록 증가되었으며, HWE 첨가구에서 색도가 다소 높았다. 아니시딘가는 가열시간이 경과될수록 유의적으로 증가되었으나, 48시간 가열 후 0.5 및 1.0 g/100 mL의 HWE 첨가구, 1.0 g/100 mL의 FWE 첨가구를 제외하면 모든 실험구에서 대조구보다 낮았다. 돈지에서는 시료의 첨가량에 관계없이 모든 실험구에서 대조구보다 낮았다. 산가는 가열시간이 길어짐에 따라 유의적으로 증가하였으나, 대두유에서 시료의 첨가량에 따른 유의차는 없었으며, 가열 48시간 이후 HWE 첨가구가 FWE 첨가구에 비해 다소 낮았다. 과산화물가도 HWE 첨가구가 FWE 첨가구보다 낮았다. TBA가는 대두유에서 가열 24시간 이후에 대조구보다 낮았으며, 돈지에서는 가열전기간 동안 대조구보다 낮았다. 따라서 와송 열풍건조시료는 동결건조 시료에 비해 항산화능이 우수하며, 돈지의 가열시 산화안정성에 효과가 있을 것으로 생각되었다.

This experiment examined the characteristics of fermented juice of epiphytic lactic acid bacteria (FJLB) prepared by the addition of glucose, sucrose and molasses as a fermentation substrate. The effect of FJLB on the fermentative quality and changes in chemical composition during fermentation of guineagrass silage were also investigated. The pH value of the silages treated with FJLB rapidly decreased, and reached to the lowest value within 7 days of start of fermentation, as compared to the control. The number of lactic acid bacteria (LAB) in the treated silages increased for the first 3 days, thereafter the number of LAB declined gradually up to the end of the experiment. Silages treated with FJLB had larger populations of LAB than the control. Ammonia-nitrogen production increased throughout the ensiling period, which in the control and no-sugar added FJLB silages were higher than the other treated silages. Lactic acid levels varied with the time of ensiling and among the silage treatments. For any sugar FJLB treated silages, the lactic acid increased initially, and then slightly reduced to less than 50 g/kg of dry matter until 49 days after ensiling, except the silage treated with glucose added FJLB. Nevertheless, lactic acid content of the control decreased constantly from the beginning of ensiling and was not found after 35 days. Moreover, acetic acid content increased throughout the ensiling period. All the FJLB treated silages had significantly (p<0.05) lower pH and ammonia-nitrogen content, while significantly (p<0.05) higher lactic acid content and V-score value compared with the control. This study confirmed that the applying of FJLB with any sugar substrate improved fermentative quality of silage.

In order to explore more efficient protein substitutes by improving the utilization of non-protein nitrogen compounds in ruminants, the experiment was undertaken. The effects of sulfur coated urea (SCU) and diuredio isobutane (DUIB) in the ruminal fluid on the concentration of $NH_3-N$, the total count of the ruminal ciliates and pH value were estimated in vitro. The results obtained from the experiment were as follows: 1. The pH of the media of the group added diuredio isobutane and sulfur costed urea tends to decrease slightly at 9 hours after the incubation, but no pH changes were observed in the media added urea alone. 2. The number of the ciliates in the ruminal fluid was slightly increased 9 hours after the incubation in all groups. 3. The concentrations of $NH_3-N$ in the ruminal fluid were gradually increased according to the incubation in vitro showing 418, 431 and $627{\mu}g/ml$ in the group added diuredio isobutane and 428, 569 and $792{\mu}g/ml$ in the group added sulfur coated urea at 0, 0.5 and 9 hours after the incubation, respectively.
