On-arrival duty free will prevent Korean outbound passengers from keeping the duty free items they purchased at the departure during their travel. Most Korean tourists have requested the airport authority to install on-arrival duty free since the grand-opening of Incheon int'l airport. Considering the fierce hub airport competition in the North East Asian region, the Korean government's decision to install on-arrival duty free is regarded as a well-timed intervention. The purpose of the research was to analyze sales correlation based on a comparison of sales of both departure and on-arrival duty free and to propose an administrative implication. Compared to business conglomerates running departure duty free, on-arrival duty free operators, who are small or medium companies, have weakness in product composition, marketing, and merchandising capabilities. According to the analysis, outbound passengers, who purchased fashion accessories and leather products at the departure duty free, tended to purchase cosmetics/perfume or liquor on the arrival duty free. Such complementary purchasing behavior of passengers showed there is barely a negative correlation between departure and on-arrival duty free.

We evaluated two herbal plants, basil (Ocimum basilicum) and lemon balm (Melissa officinalis), for their potential as repellent plants in the management of striped flea beetle (Phyllotreta striolata), in organic production of chinese cabbage. It was confirmed that striped flea beetle avoided these two herbal plants in olfactometer experiment. We conducted field experiment in which the suppressive effect of the two selected herbal plants and cruciferous crops preferred by striped flea beetle were evaluated through cultivating as inter crops and border crops, respectively. In inter-cropping experiment, unlike in vitro test, the density of striped flea beetle was low in basil- or mustard-intercropping cultivation plot, but high in lemon balm-intercropping cultivation plot. In border cropping experiment, the density of striped flea beetle on chinese cabbage in lemon balm or basil cultivation plot were approximately zero. As a result of this study, we think that border cropping of lemon balm or basil can be used to reduce preventively striped flea beetle of chinese cabbage under organic farming system.

This research aims to examine Korean regional innovation governance, find structural problems, and explore alternative strategies of regional innovation governance. Especially the alternative governance was searched through the case study of Daegu-Kyungbuk mobile cluster, of which formulation Samsung is the anchor institution. Regional innovation governance in this research is defined as a policy system to link knowledge generation & diffusion subsystem and knowledge application & exploitation subsystem, and institutional conditions to steer the system. "Social Capital Assessment Tool (SOCAT)" of the World Bank was utilized for the appreciation of cluster governance. The regional innovation governance of Daegu-Kyungbuk mobile cluster is characterized as production networks dominated by one-to-one relationship between Samsung and hardware/software developers, decentralized R&D networks and policy networks with multiple hubs. Major policy agents have not developed networks with local companies, and rare are interactions between the policy agents. Local companies, especially software developers, responded they have had experiences to cooperate for local problem solving and shared their community goal, however, the degree of trust in major local project leaders is not high. Local hardware/software developers with core technologies need to be cooperative to develop similar technologies or products in Daegu-Kyungbuk mobile cluster. Regional administrative actors, such as the City of Daegu and Kyungsangbuk-do, and diverse innovation-related institutes should build cooperative environment where diverse project-based cooperation units are incessantly created, taken apart, and recreated.

In this study, it is purpose that value-added-logistics strategy plan for cooperation and coexistence in northeast asia.. Because of the change of domestic industrial structure, Japan's super hub port plan, Yangshan Deepwater port open of china and domestic port logistics industries are faced with competition among northeast asia countries. Decreasing export volume of changed domestic industrial structure and two countries: japan, china, make a new port policy and build new ports will affect domestic port logistics industries because these industries depend on container throughput at Busan port. Now, we cannot get a lot of profit from container throughput more than before and in the future China has more ports most ships direct calling in china's port to handle china's cargo volume to get more profit at that time our plans to become a hub port in northeast need revision. Finally, we need a new strategy which is value-added-logistics strategy. But it considers cooperation and coexistence among northeast countries. So this paper suggests that value-added-logistics strategy plan for cooperation and coexistence to live in affluence together in the future.

This experiment was carried out to investigate watering with relation to growth, quality and yield of essential oil in sweet basil. The degree of water stress was taken as amount of watering. D1 was watered with 25mL for 2 weeks and 30mL from 4 to 5 weeks after planting in Wagner pot (1/20000a, ${\phi}24cm$). As this, 75mL and 90mL, 225mL and 270mL, and 675mL and 810mL were watered in D2, D3, and D4 treatment respectively. DFT was set up as water stress was not inflicted. The growth of basil in D3 and D4 was better than that of others, in which root activity was as much twice as that of D1. Essential oil of D1 was recorded the lowest content as 0.33%. The result of proline content, peroxidase activity, photosynthesis, stomatal conductance and stomatal resistance were proved D1 to be stressed. This treatment consequently increased the content of essential oil. In consideration of growth and essential oil content, D3 treatment was highest as 47.37mg in oil production per plant. Finally, D3 watered with 225mL for 2 weeks and 275mL from 4 to 5 weeks after planting could be selected on the purpose of both plant growth and essential oil production. Essential oil content of sweet basil was increased in response to water stress. For increase of essential oil yield, oil synthesis could be raised by giving water stress just before harvesting.

참취(Aster scaber)는 국화과에 속하는 여러해살이식물로 취나물로 분류되어 전국에서 재배되고 있으며 주로 남부지역에서 조기재배 작형으로 많이 재배하고 있다. 참취의 잎과 줄기는 맛과 향기가 독특하여 예로부터 생채, 묵나물 등으로 이용되어 왔으며 칼슘, 철분, 비타민 A 등이 풍부하여 건강식품으로서도 가치가 높고 한약재로도 사용되기도 한다. 최근에는 항암효과와 더불어 콜레스트롤을 저하시키는 약리적 효능이 있는 것으로 밝혀져 기능성 식품으로도 각광 받고 있다. 참취 시설재배 시 통상 3년 마다 갱신이 이루어지고 있는데 그 이유로는 시설재배지 특성상 양분의 과다투입에 의한 염류집적과 잦은 관수로 물리성이 악화되어 참취의 생육이 저하되어 수량이 감소하는 결과를 초래한다. 본 연구는 토양개량제 처리에 따른 참취의 생육과 토양 물리화학성에 미치는 영향을 검토하여 참취 시설재배 농가에 활용할 수 있는 방안을 개발하고자 시험을 수행하였다. 2018년 4월부터 2019년 9월까지 전라북도 농업기술원 허브산채시험장에서 참취 시설재배를 대상으로 하고 무처리, 볏짚 1,000 kg/10 a, 왕겨 숯 1,000 kg/10 a, 야자섬유 1,000 kg/10 a, 4처리구로 하여 시기별 생육 및 토양특성을 조사하였다. 수확기 참취 생육특성은 초장은 25.6~27.2 cm, 엽장은 8.5~9.7 cm, 엽폭은 6.3~7.0 cm, 경직경은 4.3~4.6 cm, 및 수량은 $3.3{\sim}4.0kg/3.3m^2$으로 볏짚 처리구에서 대조구에 비해 좋은 생육 상황을 보였으며 수량성 또한 많았다. 시험 후 토양화학적 특성을 조사한 결과 토양 pH는 7.4~7.5, 토양유기물 함량은 34~36 g/kg, 유효인산 함량은 386~415 mg/kg 이었으며 처리 전 토양에 비하여 유기물 함량은 증가하고 유효인산은 낮아지는 경향을 보였다. 치환성 양이온 K, Ca, Mg는 K는 $0.8{\sim}1.0cmol_c/kg$로 낮아졌고, Ca와 $8.9{\sim}10.1cmol_c/kg$, Mg는 $3.1{\sim}3.4cmol_c/kg$로 증가하였다. 토양물리성의 변화는 왕겨숯 시용에서 대조구에 비해 가장 낮은 용적밀도 $1.22g/cm^3$와 가장 높은 공극률 54.09%을 보였다. 토양 삼상은 고상은 볏짚에서 51.98%로, 액상은 야자섬유에서 28.64%로, 기상은 왕겨숯에서 29.35%로 가장 높았다. 참취 시설재배지 토양개량제 시용함으로써 토양의 유기물함량 증가와 토양의 용적밀도 감소와 토양양 공극율 증가 등 토양의 물리 화학성을 개선할 수 있을 것으로 기대된다. 본 연구는 2년차 시험 결과로서 3년차에 재검토할 계획이다.

This study was carried out to investigate the effect of a beverage that contained Bulnesia sarmienti(BSP, 2.5%) on rats to which alcohol was administered. The treatment of the BSP group reduced the serum alcohol concentration to 52%, compared to 47% in the positive control(PC) group. Similar pattell1s were observed in the enhancement of alcohol dehydrogenase(ADH), acetaldehyde dehydrogenase(ALDH), alkaline phosphate(ALP), alanine aminotransferase(ALT), asparate aminotransferase(AST), total cholesterol(CHOL), ${\gamma}$-glutamyltrasferase(GGT), glucose(GLU), total bilirubin, and total protein(TP) in the serum. Also, in the BSP group, the lipoxidase(LPO), glutathion-S-transferase(GST), XO, catalase(CAT), and superoxide dismutase(SOD) were significantly reduced, compared to the CO and PC groups in the liver. The glutathione(GSH) activity increased in the BSP group, though. These results indicate that Bulnesia sarmienti extract can enhance alcohol metabolization activity.
