The purpose of this study were to examine the effects of emotional dissonance on customer orientation and service delivery level, and to examine the mediating effects of the customer orientation. In order to verify the relationships and mediating effect, data were obtained from 199 nurses working in a general hospital in Changwon City were analyzed by using SPSS 12.0. and AMOS 5.0. The findings are as follows: Firstly, there was a negative relationship between emotional dissonance and customer orientation. Secondly, there was also a positive relationship between customer orientation and service delivery level. Thirdly, there was also a negative relationship between emotional dissonance and service delivery level. Finally, the customer orientation was a partial mediating effect on the relationship between emotional dissonance and service delivery level. Based on these findings, the implications and the limitations of the study were presented including some directions for future studies.

This study explores the partnership between government and human service nonprofits in the United States from the perspective of resource dependence theory and extends the theory with system dynamics in order to better explain government-nonprofit service delivery. The article is structured as follows. First, I introduce the historical development of the government-nonprofit partnership in service delivery in the United States. Second, I present an overview of resource dependence theory for government-nonprofit service delivery, including assumptions, key elements, claims, how well it explains the government-nonprofit service delivery, and limitations. Third, I highlight the advantages of system dynamics along with the limitations of resource dependence theory, as an attempt to revise the theory. Finally, I conclude with a summary and suggestions for the next steps in theoretical development and research.

The multilayered monolithic type transdermal delivery device has been designed and analyzed by a numerical analysis. The device consists of three layered polymer matrices which posess the different diffusion parameters, respectively. The purpose of this study was to design an ideal transdermal drug delivery device which is capable of initial burst and zero order release later on. Numerical modelings were simulated for a dispersed and a dissolved multilayered monolithic system. The results showed that the dispersed multilayered monolithic system could meet the requirements for an ideal transdermal delivery device.

In this paper we study the delivery policy of internet bookstores and recommend the improved policy to increase customer satisfaction and sales revenue. We classify customers into two, the price-sensitive and the delivery time-sensitive, and develop a new shipping method, the unhurried shipping, for the price-sensitive who are reluctant to pay shipping fee for the small purchase but willing to wait extra time for the ordered goods. The customers could get discount on shipping fee by the unhurried shipping but have to accept the longer delivery lead-time. We investigate the possible ways to reduce costs with the prolonged delivery time and show that some costs regarding shipmentand inventory could be saved in order to make up for additional shipping costs for the price-sensitive.

Agricultural products packaged for transportation are put in the various dangerous environments owing to the damage factors like vibration, shock, compression, climate etc. under the distribution process. On fruits packaging for transportation, especially, the shock and vibration is considered as the most important damage factors. A major cause of shock damage to fruits is drops during manual handling. Especially, the damages of fruits during the parcel delivery service are very serious. The parcel delivery services of fruits are increasing and contribute to increasing of farm house earning. Also, the freight vehicle is mostly used to transport the fruits. Shock and impact generated by the freight vehicle may give serious damage to fruits. The optimum packaging design of parcel delivery service of fruits during transportation is required to reduce the fruits damages. In order to design the packaging system for parcel delivery service of fruits considering the transportation environment, the comprehension of characteristics for vibration and shock generated by manual handling and acting on transportation vehicles under various road conditions and loading methods is required. This research was performed to analyze the shock characteristics, acceleration level and power spectral density (PSD) during the parcel delivery service of fruits. The overall level of recommended PSD profile in a specific transportation of parcel delivery service for fruits was $0.63G_{rms}$.

The data delivery confirmation method of MIL-STD-188-220C, which is a tactical wireless mobile Ad-Hoc communication protocol, is that a source node requires the end-to-end ack from all destination nodes and the data-link ack from 1-hop neighboring destination nodes and relaying nodes, regardless of the hop distance from a source node to destination nodes. This method has the problem to degrade the whole communication network performance because of excessive data traffic due to the duplicate use of end-to-end ack and data-link ack, and the collision among end-to-end acks on the wireless network in the case of confirming a data delivery within an 1-hop distance. In order to solve this problem, this paper has proposed the method to perform the data delivery confirmation with the improvement of communication network performance through the data traffic reduction by achieving the reliable data delivery confirmation requiring the only data-link ack within an 1-hop distance. The effects of the proposed method are analyzed in the two aspects of the data delivery confirmation delay time and the data delivery confirmation success ratio.

본 연구의 목적은 기업과 소비자간 전자상거래에서 물류운송체계의 물류비용을 상품운송 유형에 따라 분석하는 것이다. 먼저 물류운송체계를 3가지 유형 즉, 공급업체에서 소비자에게 직송하는 방법(유형 I), 자가물류업체를 통해 각 권역에 운송센타를 두어 운송하는 방법(유형 II), 3자 물류업체에게 운송에 관한 모든 일체를 위임하는 방법(유형 III)으로 분류하고 각 유형의 물류비 항목을 운송비, 보관비, 물류정보비로 구성하였다. 전자상거래에서의 물류는 다품종 소량 다빈도 특성을 가지고 있고, 주문특성 및 상황에 따라 소요물류비용이 변한다. 그러므로 본 연구에서는 대상권역의 주문에 대한 1일 주문건수 운송거리, 운송량, 그리고 1일 배정화물트럭대수에 따라 변하는 물류비용함수를 도출하였고, 가상네트웍을 구성하여 시뮬레이션 함으로서 각 운송유형의 주문특성에 따른 물류비용의 변화를 분석하였다. 하지만, 본 연구는 공급업체의 물류인프라와 운송서비스 시간에 대한 고려를 하지 않았기 때문에 현실에 적용하기에 한계가 있다. 만일 이에 대한 연구가 보충된다면 전자상거래에서 일정 단위기간 동안 상품운송에 소요되는 물류비를 좀더 정확히 추정하여 전자상거래에서의 효율적인 화물운송방안을 제시할 수 있을 것이다. 본 연구의 결과로 전자상거래에서의 1일 주문발생 빈도와 공급상품의 중량. 그리고 운송거리에 따라 변하는 물류비용을 추정할 수 있다.

The present business environment has been incurred much competition by oversupply so that customers have been to have more opportunities in selection of firms to produce required product. Under this circumstance, companies have to provide attractive proposal (for example, low price and on time delivery) to customers as considering their capacity and risk for their survival. Therefore this paper proposes a method to select customer and to propose price and due date for maximum profit in the restricted situation.

This paper considers a scheduling problem to minimize the sum of the associated scheduling (production/delivery times) cost and the delivery cost for an integrated system of a single production machine and various transportation vehicles with transportation mode selection allowed. Each transportation mode is provided with a fixed number of vehicles at the associated delivery time and cost. The proposed problem is characterized as being NP-hard. Some solution properties are also characterized. Therewith, three heuristic algorithms (called SPT-based, LWF-based and WSPT-based heuristic) and a branch-and-bound algorithm are derived. In order to evaluate the effectiveness and efficiency of the proposed algorithms, computational experiments are made with some numerical instances.

The wonderful new world of shopping - being able to order items you need by just one click. However, there is one factor that has not changed at all - customers, whether they are private individuals or public companies, want to have the product delivered to their address, and usually as fast as possible too. To achieve this, the operators of virtual shops must make use of a fully operational and efficient delivery service. The internet and its potential for creating a virtual market for millions of buyers and sellers, has generated a lot of excitement in the express delivery industry. Clearly e-commerce will cause greater growth in the business-to-residential package market. Korean express delivery industry is not an exception to this trend. Currently, while major three service providers enjoy a lion's share in Korea, a lot of small and medium companies are struggling to capture more shipments in express parcel market. Nevertheless, it will be forecasted that Korean parcel market will be consolidated and become an oligopoly market in the near future.
