All vehicles need the good quality of riding. Especially shifting shock is very important in the evaluation of the riding. Shifting shock is caused by transmission operation that one part and other part of gem are contacting together. This shock affect the feeling of driving. It is clear from these results that the shifting shock is affected by clutch pressure, pressure mode, inertia etc.

방송용 문자발생 장비는TV방송의 역사와 함께 많은 변화를 겪어 왔다. 70년대 스캐너를 거친 문자를 방송에 이용하던 시절에 이어, 한국방송(KBS)에서는 자체 기술연구소에서 초기의 'DATAVIX'와 'Vidi-master'를 거쳐 '프리즘'시리즈 등을 연이어 개발하여 방송에 활용하였고, 디지털 방송시대를 맞아 근래에는 디지털 문자발생기 '다빈치'와 '다빈치젬' (daVinci GEM)을 개발하였다. 여기에서는 가장 최근에 개발하여 현업 활용을 앞두고 있는 '다빈치젬' 에 대해 소프트웨어 구조를 소개한다.

혁신에 관한 많은 연구들이 혁신의 공급 측면에 초점을 맞춰 진행되어 왔으나, 본 연구에서는 혁신의 공급측면 대신 수요 측면에 초점을 맞춰 혁신 신뢰성에 영향을 미치는 요인을 탐색하고자 하였다. 문헌 연구를 통해 혁신 신뢰성에 영향을 미치는 요인으로 소비자의 연령과 소득수준, 개인적 네트워크, 기회인식, 역량 자신감을 선정하였다. 가설 검증을 위해 국내 2,000명의 설문 응답자를 기반으로 한 창업 분야의 글로벌 데이터베이스인 GEM 데이터를 이용하였다. 본 연구의 결과는 기업의 마케팅 활동의 효과성을 제고하는 데 실질적으로 활용될 수 있을 것이다.

This study projected the future ocean wave climate changes based on global climate change scenario using the coupled climate model HadGEM2-AO according to the emission scenarios and using regional wave model. Annual mean significant wave height (SWH) is linked closely to annual mean wind speed during the forthcoming 21st Century. Because annual mean speed decreased in the western North Pacific, annual mean SWH is projected to decrease in the future. The annual mean SWH decreases for the last 30 years of the 21st century relative to the period 1971-2000 are 2~7% for RCP4.5 and 4~11% for RCP8.5, respectively. Also, extreme SWH and wind speed are projected to decrease in the future. In terms of seasonal mean, winter extreme SWH shows similar trend with annual extreme SWH; however, that of summer shows large increasing tendency compared with current climate in the western North Pacific. Therefore, typhoon intensity in the future might be more severe in the future climate.

Generally speaking, because of complexity of engineering process, the systems engineering may be not easy to understand clearly and not easy to perform also. The status of systems engineering infrastructure of the some Korean industry is not matured yet, i.e., the systems engineering process, method, tool and environment is not implemented consistently within the steel making industry. These difficulties are more severe at the concept and basic design phase than the detail design phase relatively. Korean industry has lots of development project for the precedented systems and usually has matured domain knowledge for the precedented systems. Even though there is a mature domain knowledge of the precedented systems, the development project will lead to failure under the condition of engineering system is not well equipped. For the project success, it is very important to have a proper engineering execution system especially for the concept design and basic phase, which has a high abstraction and a large influence on the whole project. This paper proposes a minimized design process that can be easily applied to the concept and basic design phase of the precedented systems, instead of complex system engineering processes. This paper also proposes the application case of the minimized design process and methods for a Blast Furnace System.

Fifty three varieties of potatoes were planted at Alpine Potato Research station at Takwalyong Kangwando Province since in 1962. The varieties planted were introduced front Japan, the United States and Germany. The varietal reaction was divided into five classes, and the results were following. Immune : Kennebec, Isola, Cherokee, Merrimack, Yoraku, Lisili. Cosima. Highly Resistant : Antze, Ragis Isola, Hessenkrone, Plymouth, Sebago, Pungo, Sieglinde, Anco, Essex. Resistant : Tawa, B-605-10, Sequoia, Grata, Concordia, Onaway, Holing 1. Nisego. Susceptible: Nordak, Pontiac, Benimaru, Early Gem, Chippewa, Chitose, Ohjiro, Red Bake, Norland, Katahdin. Highly Susceptible: Russet Burbunk, May Queen, Earlaine, Irish Cobbler, Feldeslohn, Red Warba, Chisago, Osseo, Paunee. Warba, Norgleam, Red Beauty, Red Burt, Danshaku, Namchak (Native variety), In general the verieties introduced from the United States and Germany were more resistant to late blight than those introduced from Japan. Especially the German varieties were immune or highly resistant to the disease except Feldeslohn. Early maturing varieties were more susceptible to late blight than the late maturing varieties in southern Korea.

This study attempts to identify the relationship between inequality and entrepreneurship activities and to provide theoretical and policy implications. To do this, we use the Global Entrepreneurship Monitor (GEM), which is a survey of entrepreneurial activities at the national level, the World Income Inequality Database (WIID), and the World Bank survey data. The analysis shows entrepreneurial activities are relatively high in countries with high level of inequality. We also find GDP moderates the relationship between inequality and entrepreneurial activity. In addition, as expected, necessity entrepreneurship prevails in low income group while opportunity entrepreneurship is dominant in high income group. The study illustrates potential venue for research of entrepreneurship and inequality, whiles calls for broader studies and scrutiny.

In this study, we tried to predict the change of future land-cover and relationships between land-cover change and geo-spatial information in the Gongju area by using fuzzy logic operation. Quantitative evaluation of prediction models was carried out using a prediction rate curve using. Based on the analysis of correlations between the geo-spatial information and land-cover change, the class with the highest correlation was extracted. Fuzzy operations were used to predict land-cover change and determine the land-cover prediction maps that were the most suitable. It was predicted that in urban areas, the urban expansion of old and new towns would occur centering on the Gem-river, and that urbanization of areas along the interchange and national roads would also expand. Among agricultural areas, areas adjacent to national roads connected to small tributaries of the Gem-river and neighboring areas would likely experience changes. Most of the forest areas are located in southeast and from this result we can guess why the wide chestnut-tree cultivation complex is located in these areas and the possibility of forest damage is very high. As a result of validation using the prediction rate curve, it was indicated that among fuzzy operators, the maximum fuzzy operator was the most suitable for analyzing land-cover change in urban and agricultural areas. Other fuzzy operators resulted in the similar prediction capabilities. However, in the prediction rate curve of integrated models for land-cover prediction in the forest areas, most fuzzy operators resulted in poorer prediction capabilities. Thus, it is necessary to apply new thematic maps or prediction models in connection with the effective prediction of changes in the forest areas.
