Those making decisions are no longer located in the same workplace. Wireless technology appears promising as a method to promote group performance in circumstances dependent on time, but not member proximity. However, the success of wireless technology in group decision-making situations has not yet been proven. This paper seeks to learn whether wireless technology affects the performance of group decision-making tasks that should be resolved urgently and/or sources of idea are disconnected with on-line network.

The transmission line effects of IC interconnects have a substantial effect on a hish-speed VLSI circuit performance. The effective transmission lime parameters are changed with the increase of the operation frequency because of the skin of the skin effect, proximity effect, and silicon substrate. A new signal delay estimation methodology based on the RLC-distributed circuit model is presented ［2］. The methodology is demonstrated by using SPICE simulation and a high-frequency experiment technique.

I use panel data of sales by the foreign subsidiaries of the U.S. MNCs to examine whether trading blocs create more or less FDI and the impacts on FDI of the extended market size created by forming blocs. By employing a region-fixed effects model, I find that countries forming trading blocs attract more FDI, particularly from non-member countries, but that FDI does not always increase with the market size of the blocs. As the market size increases, FDI increases only for large blocs. However, these findings are sensitive to model specifications. A policy implication is that a country considering forming or joining a trading bloc with a view to attract FDI may want to form a trading bloc with a country or countries with a large market size.

본 연구는 세대간 애정적 결속의 양상과 결정요인을 부계와 모계로 구분하여 분석하고자 하였다. 세대간의 경제적, 도구적 정서적 지원을 통한 기능적 결속이나 잦은 만남 내지 연락을 통한 교류적 결속 거주지의 근접성을 바탕으로 한 구조적 결속의 양상과 변화에 대한 연구들과 달리 세대간 친밀감을 나타내는 애정적 결속에 대한 연구는 부족한 편이었다. 본 연구에서는 손자녀가 조부모에 대해 느끼는 정서적 친밀감을 종속변수로 하여 애정적 결속이 어떻게 나타나는지 살펴보고자 하였다. 또한 앞서 언급한 기능적, 교류적, 구조적 결속같은 요인들이 어떻게 애정적 결속에 영향을 미치는지를 살펴보고자 하였다. 이를 위하여 2011년 7월에 조사된 세대별 문화경험과 문화인식에 관한 설문조사에서 자녀가 있는 기혼이면서 양가 부모중 적어도 한분씩은 생존해 있는 30~59세 응답자 330명을 대상으로 분석하였다. 방법론으로는 '양가 조부모에게 느끼는 친밀감이 같다'라는 응답을 준거집단으로 삼은 다항로짓회귀분석을 사용하여 부계와 모계간에 변수별 영향력이 어떻게 다르게 나타나는지 보았다. 그 결과 부계에서는 경제적 지원 관계가 애정적 결속을 높이는 주요한 요인으로 드러난 반면, 모계에서는 경제적 지원뿐 아니라 도구적, 정서적 지원도 주요한 요인으로 작용하고 있음을 확인할 수 있었다.

서비스전달과정에서 고객과 서비스제공자 사이의 인적 상호작용으로 정의되는 고객접촉은 다차원적 구조물로, 서비스품질에 강한 영향을 미치는 것으로 인식되고 있다. 고객접촉의 구성차원을 탐색하고, 이들이 서비스품질평가에 미치는 영향을 검증하기 위하여 강원도 설악권 호텔고객으로부터 설문조사를 통해 수집된 자료 분석결과는 다음과 같다. 첫째, 고객접촉은 고객과 서비스종업원 사이에 이루어진 접촉의 질적 측면을 반영하는 접촉근접성과 물리적인 커뮤니케이션의 지속정도에 관련되는 커뮤니케이션시간 등 두 차원적 구조물로 나타났다. 둘째, 선행연구결과에서와 같이 고객접촉은 전반적인 서비스품질에 긍정적인 영향을 미치는 것으로 확인되었다. 셋째, 고객접촉 구성차원은 독립적으로 또 동시에 네 차원으로 밝혀진 서비스품질 차원에 전반적으로 유의한 영향을 미치는 것으로 나타났다.

The hydrodynamic interaction forces and moments induced by the vicinity of bank on a passing vessel are known as wall effects. In this paper, the characteristics of interaction acting on a passing vessel in the proximity of a semi-circle bank wall are described and illustrated, and the effects of ship velocity, water depth and the lateral distance between vessel and semi-circle bank wall are discussed. For spacing between ship and semi-circle bank wall (SP) less than about 0.2 L and depth to ship's draft ratio (h/d) less than around 2.0, the ship-bank interaction effects increase steeply as h/d decreases. However, for spacing between ship and semi-circle bank wall (SP) more than about 0.3 L, the ship-bank interaction effects increase slowly as h/d decreases, regardless of the water depth. Also, for spacing between ship and semi-circle bank wall (SP) less than about 0.2 L, the hydrodynamic interaction effects acting on large vessel increase largely as ship velocity increases. In the meantime, for spacing between ship and semi-circle bank wall ($S_P$) more than 0.3 L, the interaction effects increase slowly as ship velocity increases.

There are two methods to model the plastification of members comprising lumped and distributed plasticity. When a reinforced concrete member experiences inelastic deformations, cracks tend to spread from the joint interface resulting in a curvature distribution; therefore, the lumped plasticity methods assuming plasticity is concentrated at a zero-length plastic hinge section at the ends of the elements, cannot model the actual behavior of reinforced concrete members. Some spread plasticity models including uniform, linear and recently power have been developed to take extended inelastic zone into account. In the aforementioned models, the extended inelastic zones in proximity of critical sections assumed close to connections are considered. Although the mentioned assumption is proper for the buildings simply imposed lateral loads, it is not appropriate for the gravity load effects. The gravity load effects can influence the inelastic zones in structural elements; therefore, the plasticity models presenting the flexibility distribution along the member merely based on lateral loads apart from the gravity load effects can bring about incorrect stiffness matrix for structure. In this study, the linear flexibility distribution model is improved to account for the distributed plasticity of members subjected to both gravity and lateral load effects. To do so, a new model in which, each member is taken as one structural element into account is proposed. Some numerical examples from previous studies are assessed and outcomes confirm the accuracy of proposed model. Also comparing the results of the proposed model with other spread plasticity models illustrates glaring error produced due to neglecting the gravity load effects.

Indoor air quality at classrooms is of special concern since students are susceptible and indoor air problems can be so subtle that it does not always produce easily recognizable health effects. The main objectives of the study were to investigate the time-activity pattern of school students, to determine the sources of poor indoor air quality in schools, and to demonstrate how indoor air quality in schools causes adverse health effects such as headache, upper airway irritation, fatigue, and lethargy. Recent articles ranging from 1987-2009 related to school indoor air quality were systematically reviewed. Building-associated health effects can increase student absences from school and degrade the performance of children while in school. The reduced ventilation rate was associated with a decreased ability to concentrate along with increased adverse health symptoms. There was an association between residential proximity to busy roads and a variety of adverse respiratory health outcomes in children. Consequently, the current findings suggest the need for control strategy for school indoor air pollutants with multidisciplinary approach methods because Korea has no other natural resources except manpower especially.
