Purpose - The purpose of this study is to provide practical implications for Korean companies searching for new market opportunities. From the experimental analysis, the impact of country image on product-country image and purchase intention of Korean products are measured. In addition, this study disaggregates the impacts of country image and product-country image and purchase intention among ethnic groups in South Africa for searching further useful implications. Design/methodology - To examine South African consumers' country image and product-country image towards Korean products, data were collected between June and July 2019 through an online questionnaire, and 335 questionnaires were used for analysis. Firstly, the multivariate analysis was conducted to examine the general tendency of South African consumers' perceptions of country image to Korea, product-country image, and purchase intention among three ethnic group consumers. Then in order to verify the country image model and hypotheses of the study, we analyzed the structural models for each of the three ethnic groups and compared the sizes of the path coefficients for each groups. To compare the difference of path coefficients across ethnic groups, configural invariance, metric invariance, and scalar invariance tests were conducted sequentially. Findings - In the black and white ethnic groups, the country image had a statistically significant impact on product-country image, but it did not affect the purchase intention to Korean products. The product-country image showed a statistically significant impact on the purchase intention to Korean products in both ethnic group. However, in the coloured ethnic group consumer, the country image had a significant effect on the product-country image, but it did not affect the purchase intention of Korean products. In addition, the product-country image did not have a significant influence on the purchase intention of coloured ethnic group consumers unlike black and white ethnic group consumers. The results of this study suggest that even though differences in terms of the impact of CoI on PCI and PI were investigated for the sample of white, coloured, and black respondents, the groups seemed to respond in a reasonably comparable manner. Originality/value - South Africa occupies more than 20% of Africa's total GDP in sub-Saharan Africa and is a hub for Southern African logistics as a hub for Korean companies to enter Africa. However, it is rare to find a study focused on the determinants of consumer behavior in South Africa. In particular, this study disaggregates the impacts of country image and product-country image on consumer behavior across ethnic groups in South Africa. Therefore, this study could provide practical implications for Korean firms which desire to diversify their export markets and pioneer future markets.

Our country's coast is vulnerable area to natural disaster which the repetitive damages occur every year including a loss of lives, the damage of facilities and erosion mostly except for the east coast because of a typhoon, tidal waves, sea water overflowing by topographic structure of low-lying gentle slope and shallow sea. However, as for prevention of natural disaster occurring every year, the situation is that it's centered on the restorationcentered measures and the general disaster prevention research to minimize damages at the time of disaster occurrence is insufficient. This study intendedlop t to devehe techniques possible for real time sampling of damage prediction areas on Web in order to support decision making for damage prevention and establishment of disaster prevention policy. For this, the thematic map was produced related to disaster based on high-resolution satellite picture, and the environmental DB similar to real world was constructed through topographic construction of three-dimension integrating the parts of land and the sea. In addition, the system was developed possible for the expression of damageable regions by real time grasp of dangerous regions at the time of disaster occurrence through over flowing simulation of three-dimension, and it's intended to prepare a basis to minimize damages to disaster situations through it.

우리나라에서는 삼면이 바다와 접해있는 반도형태의 국가로 과거부터 해양수산물에 대한 양식이 이루어져 왔다. 최근에는 양식시설물들을 체계적으로 관리하기 위해 생산량에 대한 조사하고 있으며, 조사된 자료를 기반으로 생산물에 대한 가격책정을 수행하여 내수 어족자원을 안정화하고 어민생활권을 보장하고 있다. 이러한 양식시설물의 조사는 매년 항공사진 기반의 수동 디지타이징을 기반으로 하고 있다. 고해상도의 항공사진을 활용한 수동 디지타이징은 양식시설물 별 종류에 따른 특징과 시설물 운용 여부 등을 알고 있는 전문가의 지식을 기반으로 하여 정확한 구획이 수행된다. 그러나 항공사진의 활용은 생육주기가 다른 양식자원들을 모니터링하기에는 경제적, 시간적 한계가 있으며, 전문가의 지식기반 구획 역시 다수의 전문 인력 등이 투입되어야 한다. 그러므로 본 연구에서는 관측 대상지에 대한 대단위 모니터링이 가능한 위성영상을 바탕으로 양식장에 대한 외곽정보 자동으로 검출하는 프로토타입 시스템 개발에 대해 연구하였다. 연구에 사용되는 위성영상은 국내 고해상 위성인 KOMPSAT-3 위성영상 13 Scene을 양식시설이 주로 이용되는 10월에서 4월 사이에 신규 촬영하여 사용하였다. 양식시설의 검출은 가두리식, 연승식, 부류식 양식시설을 검출하였으며 검출 방법은 영상 처리를 통한 ANN 분류기법 및 Polygon 생성기법을 사용하였다. 개발된 프로토타입 시스템의 양식시설 검출율은 약 93% 정도로 나타났다. 위성영상 기반의 양식시설물 외곽정보 검출은 기존 항공사진이 가지는 모니터링의 한계를 개선할 수 있을 뿐만 아니라, 전문가가 양식시설을 탐지하고 판독하는 데 있어 유용하게 지원될 수 있을 것이다. 향후 양식장 시설물별 분류 및 영상 처리 기법의 적용을 통해 양식장 시설물 검출 시스템이 개발되어야 할 것이며, 해당 시스템을 통해 양식시설물 모니터링을 수행하여 관련 의사결정 지원에 도움이 될 수 있을 것으로 판단된다.
