It this paper we have imputed the possible outward investment patterns toward mainland China for Taiwan's apparel industry during the period from 1983 to 1991. An empirical model is then established to explicitly examine its possible impact on Taiwan apparel industry's export. This study found that outward investment by Taiwan's apparel industry in mainland China will adversely affect the Taiwanese apparel industry's own export competitiveness. In addition, the growing outward investment of Taiwan's apparel industry in mainland China is an important factor in encouraging the indirect trading activities across the Taiwan Strait.

[연구목적] 우리나라는 새로운 성장 동력을 위해 중견기업지원에 법적인 토대를 마련하였고 관련 정책들을 만들어 내기 시작하였다. 그러나 우리나라의 중견기업이라 개념이 도입 된 것은 역사가 짧아 많은 연구들이 이루어지지 못했다. [연구방법] 본 연구에서는 중견기업의 지배구조를 실증적으로 분석하여 중견기업의 지속적인 발전을 위한 시사점을 제공하고자 한다. [연구결과] 실증 분석 결과 기업 대주주 지분율은 5% 범위 내에서 음(-)의 유의한 영향을 미치는 것으로 나타났으며. 외국인 지분율의 경우 1% 범위 내에서 양(+)의 유의한 영향을 미치는 것으로 나타났다. 그리고 상장시장을 분리한 분석 결과는 대주주 지분율 코스닥 시장의 경우에는 음(-)의 값을 나타냈지만 유의한 않았으나, 유가증권 시장의 중견기업은 1% 범위 내에서 음(-)의 유의한 영향을 미치는 것으로 나타났다. 외국인 지분율의 경우에는 유의한 영향을 미치는 것으로 나타나, 중견기업의 경우에도 시장에 상관없이 외국인 지분율이 높으면 기업가치는 증가한다는 것을 실증분석을 통해서 확인했다. 시장별 연구개발집약도의 경우에는 상장시장 모두 1% 범위 내에서 양(+)의 유의한 영향을 미치는 것으로 나타나 모든 중견기업이 R&D 개발을 통해 기업의 수익 창출을 수단으로 활용하고 있는 것을 확인 했다. [연구의 시사점] 본 연구의 특징은 중견기업를 한정하여 기업지배구조와 기업 가치 간의 관련성을 실증 분석하여 우리나라의 중견기업 정책을 만들어 내는데 있어 정책방향을 결정하는데 중요한 시사점을 제공 한다고 할 수 있다. The purpose of this study is to investigate the relationship between non - linear value of advertising expenditure and contribution of Korean manufacturing industry. To do this, the empirical analysis was conducted to verify whether the firm value relevance was a nonlinear model for the period from 2006 to 2015. The results of the analysis are as follows. Advertising expenditure and donations in Korean manufacturing industries have proved to be nonlinear corporate value relevance. In addition, we found that advertising costs and donations have a non-linear U-shaped relationship among non-linear corporate value relevance. This means that advertising expenses and donations can have a positive impact on firm value, but too much advertising or donation expenditure can be translated into negative (-) effects on firm value. This implies that if the cost items of donations and advertising expenses are above a certain amount, the influence on the firm value will not only have a positive (+) influence but also will have the opposite effect. Therefore, the wise judgment of the internal decision makers including the management of the enterprise is important. The implication is that the company has proven the nonlinear relevance of presenting the necessity of accurately grasping the decision to make a donation or advertising expenses, not increasing the enterprise value or negatively affecting the enterprise value. Although the form of the curve is presented, it is necessary to study the specific cause.

<P><B>Abstract</B></P><P>A chemically modified heparin–DOCA (HD) conjugate was developed as a drug carrier for cancer therapy. HD conjugate was found to have markedly low anticoagulant activity and to form self-assembled nanoparticles in aqueous condition. We observed that HD conjugate prevented squamous cell carcinoma (SCC) and human umbilical vascular endothelial cell (HUVEC) proliferation during BrdU incorporation assays. Here, we prepared doxorubicin-loaded heparin nanoparticles by entrapping doxorubicin into the amphiphilic HD conjugate by physical interaction and characterized the properties of these nanoparticles using Dynamic Light Scattering (DLS) and Atomic Force Microscope (AFM). In this study, doxorubicin-loaded heparin nanoparticles were designed to improve the antitumor effects of nano-sized particles (range of 180 to 210?nm) at high drug-loading efficiencies in the range 64% to 96%. These doxorubicin-loaded heparin nanoparticles displayed sustained drug release patterns. It was confirmed in vivo toxicity studies that HD conjugate did not induce unexpected side effects and that DHN 20 was safer than free DOX. An in vivo study showed that HD conjugate, doxorubicin and DHN 20 (one of doxorubicin-loaded heparin nanoparticles) induced tumor volume reductions of 43%, 56% and 74%, respectively, relative to the saline treated control. These results suggest that the drug-entrapped with heparin nanoparticles might provide a novel therapy for SCC.</P>

In this study, Experimental analysis on submarine cable tension was performed for the safe and efficient laying and recovery of a submarine cable. The tension analysis was done through the analyzed data using the cable dynamic theory and the measured data using the experiment. The analyzed cable tension was able to decide requirements for the purpose of laying and recovery of the submarine cable. As the result of tension analysis for a Submarine cable, it was shown a proper feasibility to determine the laying and recovery conditions of the submarine cable.
