This study examined the factors affecting allowance management and buying behaviors and their interrelationship. The data were collected from fourth, fifth and sixth grade students of elementary students in Kimhae-city by a self-administered questionnaire. Frequency distributions, Cronbach's Alpha, Pearson's correlation analysis, regression analyses, and path analysis were analyzed by SPSS Windows. According to the regression model for the allowance management behaviors, the significant variables were the child's sex, term of receiving allowances, recognition of the allowance amount before receipt, parents' guidance before using allowances, parent-child communication about consumption, and parents' mediation of mass media. On the other hand, in the regression model for the buying behaviors, the satisfaction of the allowance amount, parents' guidance before using allowances, the amount of watching TV, parent-child communication about consumption, and allowance management behaviors were significant. The path model showed the child's sex, term of receiving allowances, recognition of the allowance amount before receipt, and parents' mediation of mass media indirectly affected the buying behaviors. In addition, the satisfaction of the allowance amount and the amount of watching 1V directly affected the buying behaviors. Moreover, parents' guidance before using allowances and parent-child communication about consumption had a direct effect and an indirect effect through the allowance management behaviors on the buying behaviors. Finally, the allowance management behaviors showed a strong positive effect on the buying behaviors.

텔레매틱스의 주요 응용분야인 차량 항법 시스템은 CIS의 지도기술과 CPS의 측위 기술에 융합되어 탄생한 것이다. 기존의 시스템들은 정점과 정점간의 최단경로를 중심으로 한 경로 탐색을 제시하였지만 교통량의 변화와 교통사고 및 수시 병목 구간 등의 교통 변화에 대해서는 능동적인 대처를 할 수 없는 시스템이다. 바꿔 말하면 현실적으로 최단경로 탐색보다는 교통 정보를 파악하며 최단시간에 목적지로 도착하는 최적경로 탐색 시스템이 필요하다. 이 논문에서는 교통 정보를 기반으로 최적경로를 탐색하는 알고리즘을 제안한다. 구체적으로 최적 경로 탐색을 위한 시스템 구조를 제안하며 기존의 최단경로 탐색 알고리즘의 문제점을 살펴보고 수집되는 교통정보의 방향성을 활용하는 최적경로 탐색 알고리즘을 새롭게 제안한다.

Objectives: Among the Korean elderly (those 65 years of age and older), the suicide rate is 80.3/100 000 people, which is ten times higher than the Organization for Economic Cooperation and Development average. Because South Korea is rapidly becoming an aging population, this high elderly suicidal rate will only get worse. Although the size of the elderly suicide problem is quite large, previous research in South Korea has surveyed restricted areas and not the entire country. Even though the factors that affect elderly suicide are complicated, there has been little research into these influencing factors. Thus, this research uses the national survey data (Community Health Survey) that was obtained in 2009. Additionally, we analyze factors affecting elderly suicidal ideation and attempts as well as the paths of these effects. Methods: Community Health Survey data obtained by the Korea Centers for Disease Control and Prevention in 2009 was used for this study. We additionally examined the factors that affect suicide with chi-squared tests, t-tests, Pearson's correlation test, and path analysis. Results: Depressive symptoms and suicidal ideation are the only factors that directly affect suicidal attempts. Demographic, behavioral, and physical activity factors have indirect effects on suicidal attempts. Conclusions: Depression has the strongest influence on suicidal ideation and attempts. Demographic, behavioral, and physical activity factors affect suicidal attempts mostly through depressive symptoms. In addition, there is a path that suggests that demographic, behavioral, and physical activity factors affect suicidal attempts not through depression symptoms but only through suicidal ideation. This means that the elderly who do not have depression symptoms attempt suicide according to their own situations and characteristics.

창의성이 조직의 성장과 발전에 중요하다는 점에서, 많은 기업들이 조직원의 창의성을 높이기 위한 방안들을 모색하고 있다. Dual pathway to creativity model 에 관련된 기존 연구에 따르면, 창의성은 두 가지 경로(인지적 유연성 혹은 인지적 지속성)를 통해 향상된다고 알려져 있다. 그러나, 이 두 가지 경로가 어떻게 활성화 되는지 이해하는데 있어서 조직원의 개인적 특질이 고려되어야 함에도 불구하고, 유연성과 지속성 중 어느 경로가 특정 성격에 더 효과적 인지에 대해서는 거의 논의된 바가 없다. 본 논문에서는, 애착 이론에 근거하여, 개인이 가진 애착 유형이 두 가지 인지적 경로에 어떤 영향을 미치는지 살펴보았다. 구체적으로, 안정 애착을 가진 개인이 (인지적 지속성이 아닌) 인지적 유연성 경로를 사용했을 때, 창의성이 향상된다고 예측하였다. 미국 피험자를 대상으로 한 온라인 실험은 본 연구의 가설을 지지하고 있다. 본 연구의 결과는, 조직 내 창의성 향상에 있어서 안정 애착이 (인지적 지속성이 아닌) 인지적 유연성과 더 적합하다는 점을 시사하고 있다.

This paper considers a make-to-order inventory-production system in which customer orders are admitted only when the number of outstanding customer orders is below a value committed by the system. We deal with general distributions for the customer order Inter-arrival, production, and replenishment lead time processes. Monotonicities of the optimal average cost with respect to these distribution parameters are established using sample path coupling arguments. When distributions are given as an exponential one, we implement a sensitivity analysis on the optimal inventory policy and show that it has monotonicities with respect to system costs using dynamic programming.

Both knowledge management and BSC practices are in its inception in the tourism field, and the study explores the relationships between knowledge and BSC perspectives using correlations and path analysis. The purpose of this study was to explore the casual relationships among tourist destination knowledge and BSC performance perspectives. The study model added knowledge perspectives to the usual BSC model (with customer, growth and learning, internal process, and financial perspectives), in addition to the modification of the financial perspectives to economic, socio-cultual and physical impact. The study found out that knowledge supports learning and growth perspectives greatly, and less extent, internal processes and customer perspectives. Learning and growth affects internal processes and customer perspectives. Internal process supports customer perspectives. Both customer and, less extent, internal process have impact on the final results. The final analysis results were different by destination type. The study concludes with recommendations for further studies including rational BSC model for tourist destinations and relationships between BSC performance indicators.

Various risk factors affect construction projects. Due to the uncertainties created by risk factors, actual activity durations frequently deviate from the estimated durations in either favorable or adverse direction. For this reason, evaluation of schedule uncertainty is required to make decisions accurately when managing construction projects. In this regard, this paper presents a new computer simulation model - the Repetitive Schedule Risk Analysis Model (RSRAM) - to evaluate unit-based repetitive building project schedules under uncertainty when activity durations and risk factors are correlated. The proposed model utilizes Monte Carlo Simulation and a Critical Path Method based repetitive scheduling procedure. This new procedure concurrently provides the utilization of resources without interruption and the maintenance of network logic through successive units. Furthermore, it enables assigning variable production rates to the activities from one unit to another and any kind of relationship type with or without lag time. Details of the model are described and an example application is presented. The findings show that the model produces realistic results regarding the extent of uncertainty inherent in the schedule.

In this paper, a memory organization and its control method are proposed for the implementation of parallel Virterbi decoders. The design is mainly focused on lowering the hardware complexity of a parallel Viterbi decoder which is to reduce the decoding speed. The memories requeired in a Viterbi decoder are the SMM(State Metric Memory) and the TBM(Traceback Memory);the SMM for storing the path metrics of states and the TBM for storing the survial path information. A general parallel Viterbi decoder for high datarate usually consists of multiple ACS (Add-Compare-Select) units and their corresponding memeory modules.for parallel ACS units, SMMs and TBMs are partitioned into smaller independent pairs of memory modules which are separately interleaved to provide the maximum processing speed. In this design SMMs are controlled with addrss generators which can simultaneously compute addresses of the new path metrics. A bit shuffle technique is employed to provide a parallel access to the TBMs to store the survivor path informations from multiple ACS modules.

This study proposes a efficient technology to control the optimal trajectory planning and real-time implementation method which can perform autonomous travelling for unmaned factory automation. Online path planning should plan and execute alternately in a short time, and hence it enables the robot avoid unknown dynamic obstacles which suddenly appear on robot's path. Based on Route planning and control algorithm, we suggested representation of edge cost, heuristic function, and priority queue management, to make a modified Route planning algorithm. Performance of the proposed algorithm is verified by simulation test.
