This study analyzes Korea's Free Economic Zone (FEZ), by particularly focusing on Incheon and Busan-Jinhae zones, using the Analytic Hierarchy Process (AHP) method and a questionnaire survey analysis. The study compares important selection criteria and satisfaction of resident companies in Incheon and Busan-Jinhae FEZs. The findings are as follows. First, the AHP method results suggest that companies in both Incheon and Busan-Jinhae FEZs are affected by location, economic society, and policy. In subordinate determining factor for land, it is ordered by ease of gaining land, inexpensive rental fee in Incheon and by convenient access to close markets and inexpensive rental fee in Busan-Jinhae. Second, the questionnaire survey results suggest high adjacent market size and easy access in Incheon FEZ and sound logistics infrastructure in Busan-Jinhae FEZ. For this reason, Incheon has a high value of logistics infrastructure and potential market near metropolitan area and Busan-Jinhae, has a high value of transportation Infrastructure near industrial district. These findings will contribute to policy data for activating and promoting the Free Economic Zone.

A and 2SM-5 type zeoli tic crystal films were synthesized on porous supports from the reaction mixture of 1.9 ${SiO}_2$1.5 $Na_20-Al_2O_3-40$ $H_20$ and $Si0_2$-0.l3 $Na_2O$-52 $H_20$-O.l2 TPAOH composition, respectively. The zeolite films were characterized by XRD and SEM. The 2SM -5 crystals grown on the porous matrix were very closely bound together. It was so difficult to obtain the perfectly intergrown crystals in the case of A-type zeolite and this crystal was transformed into P-type zeolite membrane with a prolonged reaction time. The densely intergrown A type zeolite crystal membrane could be also synthesized by the hydrothermal treatment at 100$^{\cirt}C$ after pressing the reaction mixture without addition of water. The pervaporation performance of the synthesized porous inorganic membranes was investigated for alcohol and water mixtures. A-type zeolite membrane crystallized as a thin film showed the selective \'Jermeability of water from the mixtures through the molecular sieving activity of micropores.

Based on Monte-Carlo simulation results we propose a robust analysis of variance procedure by utilizing trimmed mean and Winsorized variance. We deal with mainly the one-way classification case. We evaluate the empirical distribution of a pseudo-F statistic based on symmetrically Winsorized sum of squares when the population is normally distributed.

The purpose of this study is to identify the differences of argumentation discourses for Socio-Scientific Issues in the types of decision-making and personality traits of pre-service biology teachers. For this study, SSI discussion topics were selected according to four types of decision making: logical reasoning, suggestion of complement, emotional base, and internal conflict. Three groups were constructed based on personality traits such as extroversion, acceptability, and integrity. Each three group used the workbook specially developed and freely used the smart device for discussion. A recorder and a camcorder were used to record each group, their behavior was recorded and the written materials during the discussion were collected for the results. Using Walton's analysis framework, the collected data analyzed in terms of the source of utterance, the process of dialogue shift, and the critical movements that can judge the reasoning of utterance. As a result of the study, it was confirmed that the decision-making type of SSI topics and learners' personalities were influential in the decision-making process of SSI small group discussions. This research shows that there is a need to develop instructional materials considering decision-making types and learners' personality types of students as well as pre-service teachers for SSI discussion.

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.

본 논문은 마이크로웨이브 플라즈마 프로세스에 의하여 사이클로헥산을 이용한 다이아몬드 박막 제작에 관한 산소유량 변화 및 파라메타 변화에 따른 분광분석 결과에 대하여 논하였다. 인가전력을 증가시킴에 따라서 수소원자의 $H_{\alpha}$ 및 $H_{\beta}$의 발광강도는 증가되는 반면에 CH(B-X) 발광강도는 일정하였으며, 헥산 유량을 증가시킴에 따라 CH(B-X) 라디칼의 발광강도가 증가되고, 산소유량을 증가시킴에 따라 CH(B-X) 라디칼이 산소원자와의 결합에 의해 밀도가 감소하여 발광강도가 감소되었다. 그리고, 산소가 공급되지 않은 경우에는 비정질 또는 DLC 성분이 많이 함유된 결정성이 거의 없는 다이아몬드 박막이 성장되었으며, 산소유량을 증가시킴에 따라서 결정 표면에 잔존하는 미결합 탄소성분들이 제거되면서 결정성이 향상됨을 알 수 있었다. 본 연구를 통하여 유기용매인 사이클로헥산을 이용하여 다이아몬드 박막이 성장됨을 확인할 수 있었다.

Geodetic Satellite Positioning Techniques (NNSS, Transit, Doppler, VLBI, SLR etc.) still have much difficulty in surveying and necessity of point positions is being amplified in korea. Therefore some research institutes have being investigated point positioning using the GPS. In this study, 1 arranged the theory deal with point positioning using GPS carrier beat phase of dual frequency and estimated corrections of errors that be included in GPS observable. Also, 1 determined point position by the differencing scheme of GPS carrier phase, and analyzed the accuracy of point position. 1 suggested potentiality of geodetic point positioning using GPS carrier phase by comparing result of relative positioning with result of point positioning and analyzing result of network adjustment fixed any point position.

구리는 탄성이방성이 큰 재료로 Si 박막상에 성장시키면 (111) 방향으로 우선 배향된 박막을 얻을 수 있다. 본 연구는 이러한 (111) 우선 방위를 갖는 Cu 박막의 전기도금층의 재결정 후의 매우 평탄한 표면을 갖는 박막에서 에칭에 따른 박막의 단차와 표면형상을 통해 결정방위별 에칭 특성을 비교 분석한 결과이다. 10 vol% 질산용액에서 에칭한 결과는 구리의 용해에 따라 각 결정면에 대한 고유의 facetted surface morphology를 나타내며, 대표적인 결정 방위인 (111), (110), (100)에 대해 triangular flake, ridge and rectangular pyramidal shapes을 나타내는 것을 알 수 있었다. 에칭속도의 정량적 측정을 위해 120초간 2.2M 농도의 질산용액으로 에칭을 실시하였고, nanosize의 as-plated initial region, (111), (110), (100) oriented regions의 각각에서 383, 270, 276, 317 nm/min의 에칭속도를 갖는 것을 확인하였다. Facet surface의 관찰을 통해 에칭반응이 (111) front surface를 갖는 열역학적 평형상태에서 일어나며, 이러한 결정방위별 에칭속도 차이는 각 결정S면이 갖는 Kink or ledge의 밀도의 차이에 기인할 것으로 판단된다. 즉, 에칭이 평형상태에서 step flow mechanism에 의해 열역학적 평형상태를 유지하면서 진행이 된다. 본 연구는 향후 다양한 에칭관련 용액 효과, 구리 박막의 응력 및 불순물에 의한 효과를 볼 수 있는 기본 방법을 제공해 줄 것으로 기대한다.
