This paper analyzed the effects the regional competitiveness index on the characteristics of the regional growth. This study divides the regions in the US based on the static and dynamic standard of income for the characteristics of the regional growth. The results of the analysis are as follows. First some regions such as Alaska, Connecticut, Maryland, Massachusetts, Virginia, Washington and Wyoming have higher levels of SCI and both the rate of growth and per capita income than the national average. These are considered prosperous regions based on their high level of SCI. Second, in regards to the relation between the income level and regional competitiveness index for the regional growth, the variables such as human resource, science technology, business incubation, openness, safety and environmental policy are significant. Third, infrastructure, human resource, science technology and openness are the significant variables concerning the relation between the rate of income growth and regional competitiveness index for the regional growth.

도시화에 따른 도시문제발생이라는 결과로 미루어 볼 때, 지속적인 도시 성장을 위한 도시 성장 관리는 필수적이며, 이것을 위해서 도시지역을 추출하는 것은 도시의 성장 추이를 파악할 수 있게 한다는 점에서 매우 의미 있는 일이다. 본 연구에서는 도시 성장 모니터링에 있어서 정규식생지수(NDVI)와 정규시가지화지수(NDBI)를 결합한 방법의 활용성을 규명하는데 목적을 두었다. 이를 위해 토지피복분류에 일반적으로 사용되는 감독 분류기법과 도시지역추출에 이용되는 NDVI와 NDBI를 결합한 방법(식생지수결합법)으로 1988년과 2000년 두 시기의 Landsat TM 영상을 이용하여 도시지역을 추출하고 일치도를 분석하였다. 분석 결과, 1988년 식생지수결합법과 감독분류기법으로 추출한 도시지역의 일치도는 98%, 식생지수결합법 비도시지역으로 추출된 지역이 감독분류기법으로는 도시지역으로 추출될 확률은 37.35%로 나타났고, 같은 경우 2000년은 각각 99.3%와 7.7%로 나타났다. 이를 통해 식생지수결합법을 사용한 도시지역 추출 결과와 감독분류기법을 사용한 도시지역 추출 결과의 일치도가 비교적 높게 나타남을 알 수 있었다. 또, 각 기법을 통한 도시지역 추출 결과와 실제 도시 검사점과의 일치도의 분석을 통해서도 도시지역 추출 결과의 일치도가 비교적 높게 나타났다. 따라서 분류를 통한 도시지역 추출 방법에 비해 식생지수결합법을 이용한 도시지역 추출이 절차상 수월한 점을 감안하면 도시지역 추출에 있어서 식생지수결합법의 효율성을 입증할 수 있었다.

This paper aims at developing a new index that represents the Korean new growth industries, which is named the Korea Future Technology Index(KOFTI). The KOFTI is designed to provide a reliable and econometric index based on which the Korean government searches for new growth engines. The KOFTI is composed of three individual indexes such as the Economic Impact Index, the Future Strategy Index, and the Technological Influence Index. The KOFTI is applied for 62 star brands, which have been promoted by the Korean government for the korean future industrial competitiveness. The top 13 leading industries are drawn from the calculation of the KOFTI for 62 star brands.

The purpose of this study is to compare traditional productivity and environmental productivity of Chinese 28 provinces for 1997-2005. The Eastern, the Central and the Western regions show higher M productivity indices than ML productivity indices before 2000 year, but two productivity indices of three regions report almost similar levels after 2000 year. The M productivity indices were higher than the ML productivity indices in the most provinces for 1997-2005. It implies that the Chinese regional economies have difficulties in the production activity reducing pollutants and increasing desirable outputs simultaneously. In the future, the Chinese 28 provinces need to change the direction of economic growth in the way that pursuits economic growth restraining pollution emission quantities thoroughly and should improve the concrete investment for clean technology of pollutant treatment, reinforcement of environmental regulation, and effectiveness of enforcement law.

Subcritical crack growth in rock material can occur under monotonic and cyclic loading. Subcritical crack growth plays an important role in evaluating the long-term stability of structures in rocks. This paper presents the results of studies conducted to determine subcritical crack growth parameters under monotonic and cyclic loading in rock-like material. The constant stress rate method was employed for monotonic loading. The subcritical crack growth parameter of n under cyclic loading was determined by the relation between the rate of crack growth per cycle and stress intensity factor range. The specimens contained pre-existing flaws with 45 and 60 degrees of inclination angle and flaws spacing and continuity were varied to arrange crack growth in shear or tensile manner. The results show that the parameter of n is almost constant regardless of the applied load conditions such as monotonic and cyclic or shear and tension.

기후변화나 인위적인 요인 등에 의해 수문 자료에 비정상성(nonstationarity)이 나타나면서 정상성 가정 하에서 수행되는 빈도해석으로는 정확한 확률수문량 산정이 어려운 실정이다. 최근 이를 보완하기 위한 비정상성 빈도해석에 대한 연구가 진행되고 있고, 이와 더불어 비정상성 지역빈도 해석에 대한 관심도 높아지고 있다. 비정상성 지역빈도해석은 대개 홍수지수법(index flood method)을 기반으로 진행되고 있는데, 홍수지수와 성장곡선(growth curve)에 시간에 따른 변화를 고려하느냐의 여부에 따라 다양한 형태의 홍수지수모형이 적용되고 있다. 본 연구는 다양한 형태의 홍수지수모형의 성능을 평가하여 비정상성 자료에 적합한 형태를 선정하는 것을 목적으로 한다. 이를 위해 위치 매개변수가 시간에 따라 변화하는 비정상성 GEV 분포(GEV100)를 모분포로 하는 지점들로 지역들을 구성하고, Monte Carlo 모의를 통해 발생시킨 자료에 여러 형태의 홍수지수모형을 적용하여 각 모형의 성능을 평가하였다. 모의실험 결과 홍수 지수는 시간에 따른 변화가 없고, 성장곡선은 시간에 따라 변화하는 형태인 홍수지수모형이 다른 형태의 모형에 비해 대체로 더 정확한 확률수문량을 산정할 수 있는 것으로 나타났다. 또한 우리나라 기상청 관할 강우 관측 지점들 중 GEV100 분포가 적합한 것으로 선정된 지점들을 하나의 지역으로 구성하여 모의실험에서 적용한 것과 동일한, 여러 형태의 홍수지수모형을 적용한 결과 모의실험 결과와 일치하게 성장곡선에만 비정상성 고려된 홍수지수모형이 상대적으로 정확한 확률강우량을 산정하는 것으로 나타났다. 따라서 GEV100 모형 기반의 비정상성 지역빈도해석을 수행하기 위해서는 성장곡선만 시간에 따라 변화하는 홍수지수모형이 적합할 것으로 판단된다.

The smoke hazard assessment of building materials focusing on smoke performance index-II (SPI-II) and smoke growth index-II (SGI-II) was investigated. The test species used were Japanese cedar, spruce, lauan, and red pine. The smoke characteristics of wood specimen were investigated using a cone calorimeter (ISO 5660-1). SPI-II was measured after the combustion reaction increased by 1.31~2.15 times based on red pine. The fire risk by SPI-II increased in the order of spruce, lauan, Japanese ceda, and red pine. SGI-II increased by 1.18~2.55 times compared to that of Japnese ceda. The fire risk caused by SGI-II increased in the order of Japanese ceda, spruce, lauan, and red pine. CO_mean concentrations were ranged from 58 to 133 ppm, which was higher than permissible exposure limits of the occupational safety and health administration (OSHA), 50 ppm. Therefore, woods such as red pine containing various volatile organic substances, were considered to be highly smoke hazardous due to low SPI-II and high SGI-II.

The importance of startups and ventures in the Korean economy is growing. This study measured whether the start-up and venture ecosystem is growing, including the growth of startups and ventures. The startup and venture ecosystem consists of startups and ventures, investors, and government, which are the main actors of the 'ecosystem', and their movements were measured with 25 quantitative indicators. Based on the original data of the time series from 2010 to 2020, the startup and venture ecosystem index was calculated by applying weights through the comprehensive stock index method and AHP. In 2020, the startup and venture ecosystem grew 2.9 times compared to 2010, and the increase in the government index had a significant impact on growth. Also, the individual indicators that make up each index in 2020, the corporate index had the greatest impact on the growth of the number of 100-billion ventures, while the investment index had a recovery amount and the government index had a significant impact. Based on the original data, the startup and venture ecosystem index was analyzed by dividing it into ecosystems (startup ecosystem and venture ecosystem), industry by industry (all industries and manufacturing industry), and region (Korea and Busan). As a result, the growth of the startup ecosystem over the past decade has been slightly larger than that of the venture ecosystem. The manufacturing was lower than that of all industries, and Busan was lower than that of the nation. This study was intended to use it for the establishment and implementation of support policies by developing, measuring, and monitoring the startup and venture ecosystem index. This index has the advantage of being able to research the interrelationships between major actors, and anyone can calculate the index using the results of official statistical surveys. In the future, it is necessary to continuously update this content to understand how economic and social events or policy support have affected the startup and venture ecosystem.
