中華經濟圈 對頭에 따른 우리나라의 中華資本 誘致政策 樹立에 관한 硏究
장동식(蔣東植) 법무부 국제법무정책과 2003 통상법률 Vol.- No.53
This study deals with the Korean foreign investment policy measures to induce Chinese capital in line with formation of Chinese Economic Community in East Asia. In this paper, Chinese capital is defined as capital including both capital in China and Chinese capital from the Chinese society in East Asia. Three policy measures that help induce Chinese capital are proposed as follows. First, the inducement policy of Chinese capital must link with economic policies to develop korea into an economic hub in northeast Asia. Second, Korea must establish the national office for foreign investment, thus helping induce Chinese capital. Third, Korea must host capital from Chinese Economic community in East Asia into financial industry, IT industry, hotel and tourism industry. An important implication in this paper is that economic cooperation with Chinese Economic Community will be successfully established with inducement of Chinese capital into korea.

반복회수에 대한 하중-변형률 선도로부터 구산 잔류변형률의 비교 결과에서 피로하중하의 GFRP관의 강성은 GFRP관의 유리섬유의 적층수가 클수록 크게 나타났으며, 이러한 현상은 피로파괴 직전까지 나타났다. 아울러 본 피로실험 결과를 회귀분석하여 구한 S-N선도에 의하면 정적극한강도 백분율에 대한 피로강도는 GFRP관의 유리섬유 적층수가 증가할수록 증가하였으며, 유리섬유의 적층수가 15, 25, 35층인 GFRP관의 반복회수 200만회에 대한 피로강도는 정적극한강도는 각각 약 75.2%, 79.5%, 84.2%로 나타났다. In the comparison result of residual strain calculated from the load-strain curve under the repeated loading cycles, it was found that the larger the laminates is, the larger the stiffness of GFRP pipes under fatigue load is. This phenomenon is true until the fatigue failure. According to the S-N curves drawn by the regression analysis on the fatigue test results, the fatigue strength for percentage of the static ultimate strength increases by increasing the laminates of GFRP pipes. The fatigue strength for 2, 000, 000 repeated loading cycles In GFRP pipes with the laminates varing 15, 25, 35 shows 75.2%, 79.5%, 84.2% on the static ultimate strength, respectively.

Myopia is a major public health problem and its prevalence is increasing over time in Korea. The main treatment options of myopia correction are spectacle lenses, contact lenses,refractive surgeries such as photorefractive keratec-tomy (PRK), laser in situ keratomileusis (LASIK), and laser epithelial keratomileusis (LASEK), phakic intraocular lenses and clear lens extraction. Each treatment option has its own indications and contraindications, and not only has some advantages over the others but also some disadvantages. The evidence shows that most therapies for myopia have stable and safe results, although some do not. Customized therapy,real time tracking and sensing, and femtosecond laser-assisted surgeries might be ubiquitous in the near future. This review will discuss current treatment options for myopia and will introduce possible future therapies.
