Chemical industry, as one of the basis industries of the country, is characterized by converged high-end technology and large scale capital investment. In 2018, the government announced "The Strategy for Chemical Industry Development" with the vision of 'An Upgrade to the Advanced Chemical Industry'. In the meantime, the advanced chemical industry in Korea has been developed not by its own R&D, but by the upgrading of technologies and processes through the technology transfer from developed countries. The method of technology transfer was mainly achieved with international joint ventures (hereafter IJV) linked with technology transferors from developed countries. As it is necessary to grasp the determinants of the technology transfer and their importance to promote the transfers through IJVs, this relative importance analysis study was conducted by using the method of quantifying experts' opinions (AHP) on the determinants of the technology transfer of both parties. As a result of the analysis, in the Hierarchy1(PEST factors), the technology transferees focus on economic factors such as 'profitability of technology transfer' and 'cost efficiency', while technology transferors considered technical factors such as 'operational excellence (abilities to continuously improve technology process)'. In addition, transferors and transferees have different priorities for technology transfer determinants in all areas of Hierarchy 2 (sub-determinants). This suggests that Korean government or enterprise should shift the policy direction toward 'technology-oriented' when they promote advanced-technology transfer through IJVs.

REACH는 지속가능한 화학물질관리의 기본 축이 되는 법령으로서 현재 및 미래 세대의 건강과 환경을 보존하는 동시에 화학산업의 경쟁력을 높이기 위해 제정된 유럽연합의 신 화학물질 통합관리 제도이다. 신화학물질 관리정책의 핵심인 REACH 제도는 2003년 10월 EU지뱅위원회(안)이 발표된 후 3년여 간의 토론을 거친 수정안이 2006년 12월 18일 EU이사회에서 만장일치로 최종 채택되었다. 2006년 11월~12월 2차 독회와 표결을 거쳐 REACH 최종법령은 2007년 6월부터 시행됨에 따라 EU와 주요 국가의 산업체가 긴박하게 움직이고 있는 상황이다. 본 고에서는 REACH 제도 도입 배경 및 최근 국제 동향에 대해 살펴보도록 한다.

The direct reactions of titanium tetrachloride with piperidine and diphenylamine in dichloromethane have been studied by examining the isolated reaction products. In the reaction with piperidine, titanium tetrachloride undergoes both addition and substitution reactions as in the following: $TiCl_4+C_5H_{10}NH{\to}TiCl_4{\cdot}C_5H_{10}NH$$TiCl_4+C_5H_{10}{\to}TiCl_3{\cdot}NC_5H_{10}+HCl$ The addition reaction is relatively fast and completed in minutes whereas the substitution reaction is very slow. The both reaction products coprecipitated with piperidine hydrochloride formed during the substitution reaction were isolated and characterized. The reaction with diphenylamine resembles to the above reaction but the addition compound could be obtained in pure crystal form.

Organic solvent resistant hollow fiber membranes were fabricated via a thermally induced phase separation (TIPS) method using Polyketone polymer, a material with excellent resistance to organic solvents. The PEG300, DMSO₂ and Glycerine called the "green solvents" were used as diluents for TIPS method. The spherulite structure was formed with DMSO₂ by S-L phase separation behavior whereas the bicontinuous structures were formed with PEG300 and Glycerine, respectively. The morphology of the PK hollow fiber membranes was investigated using SEM. The pure water permeability and the durability test were conducted to understand the permeation properties of PK hollow fiber membranes. The tensile strength test was conducted for the property of mechanical strength. In this study, the fabrication of PK hollow fiber membranes with various diluents was discussed to understand the correlation between diluent and polymer in detail.
