본 연구는 기업이 기술제품을 도입한 후에 내부에 확산시키려고 하는 실행단계에서 직면하는 혁신저항에 영향을 미치는 요인과 혁신저항을 줄이고 확산을 증진시키는 확산촉진활동을 설명하여 2B 마케팅 상황에서 기술제품의 조직내 혁신저항-확산모델을 도출하였다. 기업에서 기술제품을 조직내에 확산시킬 때는 구성원들의 혁신저항을 접하게 된다. 소비자 행동에서는 혁신저항에 영향을 주는 변수로 개인변수와 제품변수를 제시하고 있지만 2B 마케팅에서는 조직구조변수와 구매센터변수가 추가적으로 영향을 주게 된다. 중앙집권화, 공식화정도가 높은 기업에서는 구성원들이 혁신저항을 가지면서도 사용할 수 있다. 이러한 경우에는 판매기업과 구매기업의 관계가 단기적인 관계로만 그칠 수 있다. 또한 구매센터 참여정도가 적고 구매센터가 집중화되어 있으면 혁신저항이 커지고 단기적인 관계만 형성될 가능성이 커진다. 그리고 제품의 지각된 위험, 적합성에 따라 혁신저항의 정도가 달라질 것이다. 그리고 사용자 개인의 지각된 자기능력, 현 제품의 만족도 등이 의미있는 조절 변수 역할을 할 것이다. 그러므로 장기적인 관계로 이어지기 위해서는 혁신저항을 줄이는 교육훈련, 제품개선, 부서간 조정, 개인적 동기 부여와 같은 확산촉진활동이 있어야 한다. 따라서 본 연구를 통해 판매기업과 경영자들은 기술제품에 대한 혁신저항을 극복하고 제품을 확산시킬 수 있는 학문적, 관리적 시사점을 얻을 수 있을 것이다.

Since electrical resistivity of concrete can be measured in a more rapid and simple way than chloride diffusivity, it should be primarily regular quality control of the electrical resistivity of concrete which provides the basis for indirect of quality control of chloride diffusivity during concrete construction. If this is realized, the electrical resistivity of concrete can be a crucial parameter to establish maintenance strategy for marine concrete structures. The purpose of this study is to develop, design and test a surface electrical resistivity measurement protocol. Microstructural affecting factors such as capillary water, porosity, tourtousity, and so on, on the electrical resistivity of concrete were examined taking into account for mixing proportion properties, and hydration stage. This study can provide a non-destructive approach for durability design of marine concrete. From the relationship between electrical resistivity and chloride diffusivity, it is expected that the result is subsequently used as a calibration curve for an indirect control of the chloride diffusivity based on regular measurements of the electrical resistivity during concrete construction.

Studies were made on differences among types and varieties of rice in stomatal density and gas diffusion resistance, and on the relationship between these traits and photosynthetic rate. Significant differences among types and varieties were found stomatal density and gas diffusion resistance. Generally, stomatal density was higher in indica varieties than in Japonica varieties, gas diffusion resistance was lower in the former than in the later, in varieties developed through indica-japonica hybridization it was intermadiate. The stomatal density was closely positively correlated with the gas conductivity and the net photosynthetic rate, was not correlated with single leaf area, and had significant negative correlation with specific leaf weight. Higher photosynthetic rate of indica varieties mainly results from its high stomatal density and low gas diffusion resistance. The result also suggested that high photosynthetic rate might be obtained if the high stomatal density and low gas diffusion resistance in indica could be combined with the larger specific leaf weight in japonica through crossing between two.

반도체 소자의 고집적화에 따라 채널길이와 배선선 폭은 점차 줄어들고, 이에 따라 단채널효과, 소스/드레인에서의 기생저항 증가 및 게이트에서의 RC 시간지연 증가 등의 문제가 야기되었다. 이를 해결하기 위하여 자기정렬 실리사이드화(SADS) 공정을 통해 TiSi2, CoSi2 같은 금속 실리사이드를 접촉 및 게이트 전극으로 사용하려는 노력이 진행되고 있다. 그런데 TiSi2는 면저항의 선폭의존성 때문에, 그리고 CoSi2는 실리사이드 형성시 과도한 Si소모로 인해 차세대 MOSFET소자에 적용하기에는 한계가 있다. 반면, NiSi는 이러한 문제점을 나타내지 않고 저온 공정이 가능한 재료이다. 그러나, NiSi는 실리사이드 형성시 NiSi/Si 계면의 산화와 거침성(roughness) 때문에 높은 누설 전류와 면저항값, 그리고 열적 불안정성을 나타낸다. 한편, 초고집적 소자의 배선재료로는 비저항이 낮고 electro- 및 stress-migration에 대한 저항성이 높은 Cu가 사용될 전망이다. 그러나, Cu는 Si, SiO2, 실리사이드로 확산·반응하여 소자의 열적, 전기적, 기계적 특성을 저하시킨다. 따라서 Cu를 배선재료로 사용하기 위해서는 확산방지막이 필요하며, 확산방지재료로는 Ti, TiN, Ta, TaN 등이 많이 연구되고 있다.

This paper focuses on the systematic approach to handle possible resistance by the members of an organization which adopts ERP system. We also analyze various factors that affect the members' receptivity to the new system. The analytic result from the data of 169 universities shows that emotional factors such as fear and doubt play a significant role, while other factors such as relative advantages of efficiency, relative advantages of system and technology support does not. This research demonstrates both the psychological and behavioral aspects of resistance to technology, and then provides a new perspective on the adoption and diffusion of technological innovation in an organization by systematically analyzing the possible negative consequences while the majority of existing research emphasizes on the rosy prospects of the innovation.

Gas diffusion layer (GDL) compression is important parameter of polymer electrolyte membrane fuel cell (PEMFC) performance to have an effect on contact resistance, reactants transfer to electrode, water content in membrane and electrode assembly (MEA). In this study, the effect of GDL compression on fuel cell performance was investigated for commercial products, JNT20-A3. Polarization curve and electrochemical impedance spectroscopy was performed at different relative humidity and compression ratio using electrode area of 25 ㎠ unit cell. The contact resistance was reduced to 8, 30 mΩ·㎠ and membrane hydration was increased as GDL compression increase from 18.6% to 38.1% at relative humidity of 100 and 25%, respectively. It was identified through ohmic resistance change at relative humidity conditions that as GDL compression increased, water back-diffusion from cathode and electrolyte membrane hydration was increased because GDL porosity was decreased.

Leaf diffusive resistance (LDR), stomatal density, length of guard cell and hair density of leaves of 6 oak species were determined under withdrawal of water, and their strategies of drought stress were analyzed by principal component analysis. LDR of Quercus acutissima, Q. aliena and Q. serrata increased earlier than those of the other species at high leaf water potential $({\Psi}_{leaf})$ or low water saturation deficit (WSD), which was an avoidance mechanism reducing damage by water stress. Q. variabilis with low stomatal density, small stomatal size and high hair density had avoidance mechanisms increasing LDR at high $({\Psi}_{leaf})$ However, Q. mongolica and Q. dentata increased LDR at low $({\Psi}_{leaf})$ as xeric species do. Results from principal component analysis on the 15 variables related to strategies of drought stress indicated that the 6 oak species were divided into 2 groups: (1) Q. acutissima, Q. aliena and Q. serrata as mesic habitat species and (2) Q. variabilis, Q. mongolica and Q. dentata as xeric habitat species. Among three xeric species Q. acutissima differed from the other two species in the drought strategies such as high hair density, low stornatal density, high leaf area ratio, stomatal closing at low $({\Psi}_{leaf})$ and small cell wall elasticity. The results could reasonably explain their drought strategies in natural habitat.
