Soil Classification of 70 golf courses in Korea was identified according to the detailed soil map from Rural Development Administration. Golf courses (GL) soils were included 6 great soil groups(by the old system) and 8 great groups (by the new system) and 17 soil series. Most abundant great soil groups by old system were Red yellow soils(50% of GL) and Lithosols (44%) and by new systems, Dystrochrepts(74%), Eutrochrepts(8.6%) and Hapludults(7.1%) were main great soil groups. Major soil series were indentified as Osan(27.1% G.F), Samgag(18.6%), Yesan(11.4%), Songsan(8.6%) and Daegu(7.1%). Characteristics of great soil groups and soil series were summaried or tabled for golf course management.

Basically the dynamics of the fixed-wing aircraft is based on the airspeed which is relative to the wind, but when it comes to the track guidance and control, ground speed is the factor to be considered. Especially in the case of low-speed fixed-wing unmanned aerial vehicles the difference between the airspeed and the ground speed is significant depending on wind conditions, so that the heading control and the course control have to be designed separately. This paper represents the course control method using the pre-designed heading control gains which meet the desired characteristics. Also, waypoint guidance and control algorithms are suggested applying this control method. Finally the robustness of the proposed method is confirmed by 6-DoF nonlinear simulation.

Offshore oil production faces several difficulties caused by oil price decline and unexpected changes in the global petroleum logistics. This paper suggests a stochastic model for optimizing the offshore oil production under uncertainty. The proposed model incorporates robust optimization and restricted recourse framework, and uses the lower partial mean as the measure of variability of the recourse profit. Some computational experiments and results based on the proposed model using scenario-based data on the crude oil price and demand under uncertainty are examined and presented. This study would be meaningful in decision-making for the offshore oil production problem considering risks under uncertainty.

Alkyl polyglucosides (APG), so called natural nonionic surfactants, are prepared with glucose from corn starch and fatty alcohol from palm and/or coconut oil. When we studied on interfacial properties of APG, surface and interfacial tension, cmc, foaming and effectiveness, according to degree of polymerization of glucose unit (D.P.=1.2~1.8) and alkyl chain length, the former hardly affects but the latter greatly affects on them. The order of detergency for fatty acid soils decreased as followings ; APG 0814> APG 1214> APG 10> APG 0810> APG 08, and the samples with lowest interfacial tension and maximum adsorption had a better detergency.

This study reports water-resistant oil-in-water (O/W) emulsion-based sunscreening formulations prepared using a poly(ethylene glycol)-poly(${\varepsilon}$-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG) triblock polymeric surfactant. As a result of a variety of outdoor recreational activities such as swimming and hiking, consumer needs for development of advanced water-resistant sunscreen formulations are increasing. Water-resistant sunscreens are mostly based on water-in-oil (W/O) emulsions, because they should not be wiped off by water or sweat. However, the W/O emulsion formulations have a disadvantage in that the feeling of use is oily and difficult to remove. On the other hand, the O/W emulsion formulations are excellent in achieving the better skin feel as well as the easier removal. However, it is difficult to provide the O/W emulsion formulations with the water-repelling performance, since re-emulsification likely occurs upon getting touch with water. To solve this problem, this study proposes a O/W emulsion-based sunscreen formulation, a triblock polymeric surfactant having relatively high interfacial tension HLB value (~ 10). This allows the sunscreen formulations to exhibit the improved water repellence function by preventing their re-emulsification. The sunscreen formation system prepared in this study would be useful for diversification of functional sunscreen products, taking advantages of its excellent emulsion stability, UV protection performance, long lasting water-resistant function and selective cleansing effect with only foam cleanser.

유니콘기업을 목표로 하고 있는 국내 스타트업들이 아직까지 국내 투자유치와 코스닥시장 IPO를 목표로 삼고 있고, 해외 판로개척, 해외투자 유치 및 M&A를 통한 글로벌 진출이 활성화 되어 있지 않기 때문에 현재까지의 제2벤처붐은 절반의 성공이라 볼 수 있다. 현 정부에서도 스타트업의 글로벌 진출을 중요한 정책 아젠다로 보고 있는 바, 중소벤처기업들의 글로벌 진출 및 사업화 성공 요인을 분석하기 위한 연구가 필요한 시점이라 할 수 있다. 본 논문은 중소벤처기업의 글로벌 경영성과에 미치는 요인들을 살펴보기 위해 국제경영이론 중, 글로벌진출 성공요인과 관련된 자원기반관점과 동적역량관점의 선행연구를 검토해보고, 기업의 혁신역량과 개방형 혁신활동이 기업의 글로벌 성과에 미치는 영향을 실증분석을 통해 살펴보고자 한다. 아직까지 스타트업 또는 벤처기업들을 대상으로 글로벌 진출 성공요인을 도출한 연구가 부족하다는 측면에서 본 연구는 기존 연구들과 차별성이 있음을 밝힌다.

The purpose of this study was to examine differences in motivation of the tourists, who visited the Daegu Ole Palgong mountain courses, according to the slow tourism tourists' demographic characteristics and use-behavior, and to examine the relationships between motivation and the degree of satisfaction of tourists and behavioral intention. Also, it was to present motivations and characteristics of slow tourism tourists and the accompanying managerial implications. In order to achieve this research purpose, a survey was conducted from May 8, 2010 to May 23, 2010 on the tourists who visited Daegu Ole Palgong mountain courses. The results of testing the hypotheses through empirical analysis were as follows. First, differences in motivations according to demographic characteristics and demographic characteristics and the use behavior of the tourists were partially adopted. Second, there were significantly positive (+) relationships between the motivations of visitors to the Daegu Ole Palgong mountain courses and the overall degree of satisfaction. Finally, the overall degree of satisfaction with the visits to Daegu Ole Palgong mountain courses had significantly positive (+) relationships with revisit intentions. These imply that it is necessary to provide differentiated strategies and programs and inducing strategies in accordance with the results presented. as well, marketing strategies to enhance the degree of satisfaction of the tourists should be considered.

The goal of the study is to analyze aggressive attempts of China and Japan to construct the Siberia oil pipeline in a direction to its advantage from the political economic perspective. The pipeline is to affect significantly energy Policies in the Northeast Asia in the future. First this Paper reviews the ongoing Processes of the Pipeline construction thus far. Next, domestic and foreign factors in Russia which are related to the laying of the pipeline, were taken into consideration. Applicability of the mercantilist and liberalist approaches to the energy supply of Russia were examined in the situation. As a result, the dualistic approach in energy supply was found to be limited in its real applicabilities and the political economic approach proved to be more suitable in that Russia currently seeks economic security in Northeast Asia. Finally the implications of the Siberia oil pipeline construction were suggested for the current energy situation in Korea.
