This study conceptualized the factors affecting college students' consumer decision-making styles from the perspective of consumer socialization. A number of antecedent variables identified by preceding studies (age, gender, place where one grew up, job experience, main reason for working, amount of allowance, family income, socio-economic status) and socialization agents such as family, peers, mass media were included in the analysis. This study extends previous studies by examining a theoretical link between the antecedent variables and socialization agents. Three hundred and forty one undergraduate students in Daejeon were participated in this study. Stepwise multiple regression md path analysis were conducted. The results of this study are as follows: 1. Six consumer decision-making styles were identified. 2. The influence of the socialization agents, especially mass media and several antecedent variables, especially gender and main reason for working, played important roles in consumer decision-making styles. 3. Several antecedent variables, especially gender and family income, were related only with the influence of socialization agents. 4. Six path-analysis models that illustrate the relationships among the antecedent variables, the socialization agents and consumer decision-making styles were proposed.

We propoes a study on the dynamic characteristics analysis and position control of 5-degree multi-joint manipulators for untact remote working at construction sites and manufacturing plants. The main frame of freedom multi-joint manipulator consists of five elements, boom cylinder, boom cylinder, arm cylinder, bucket cylinder, and rotation joint and link. In addition, the main purpose of the proposed system is to realize the work of the manufacturing process or construction site by remote control. Motion control of the entire system is a servo valve control method by hydraulic servo cylinders for one to four joints, and a servo motor control method is applied for five joints. The reliability of the proposed method was verified through performance experiments by computer simulation.

This paper proposes the controller for biped robot using intelligent control algorithm. The main purpose of this paper is to design the robot controller using Hierarchical Mixture of Experts(HME). The neural network direct control method will be applied to the control scheme for the biped robot and neural network will learn the dynamics of biped robot. The teaming scheme using a intelligent controller to biped robot is developed. The teaming scheme uses a HME controller combined with a inverse biped robot model. The controller provides the control signals at each control time instant. Simulation results are reported for a seven-link biped robot.

The major problem at a branch point for point-to-multipoint available bit rate(ABR) services in asynchronous transfer mode (ATM) networks is how to consolidate backward resource management(BRM) cells from each branch for a multicast connection. In this paper, we propose an efficient feedback consolidation algorithm based on an adaptive dynamic threshold(ADT) to eliminate the consolidation noise and the reduce the consolidation delay. The main idea of the ADT algorithm lies in that each branch point estimates the ABR traffic condition of the network through the virtual queue estimation and the transmission threshold of the queue level in branch points is adaptively controlled according to the estimation. Simulation results show that the proposed ADT algorithm can achieve a faster response in congestion status and a higher link utilization compared with the previous works.

In this paper, the direct and indirect adaptive controller are combined based on the Lyapunov synthesis approach. The Proposed controller is constructed from RBF Neural Network and weighting parameters are adjusted on-line according to some adaptation law. In this scheme, fuzzy IF-THEN rules are used to decide the combined weighting factor. In the results, proposed controller has the main advantages of both the direct adaptive controller and the indirect adaptive controller. The effectiveness of the proposed control scheme is demonstrated through simulation results of control for one-link rigid robotics manipulator.

The main objective of this paper is to explore the feasibility and potential benefits of HFLC series compensator as a power flow controller in an ac power system. To accomplish this goal, the detailed 5 [KHz] model for EMTP simulation study is developed. Among the issues considered are analysis, tank circuit design, link frequency selection, harmonics and filter requirement, control and damping effect. The technical evaluation performed in this research can be used in future power network design and operation.

A novel digital control algorithms are developed for an active power filter (APF) using a pulse-width modulated (PWM) rectifier with current link. A main control algorithm compensating both the reactive power and harmonic currents with fast dynamic response is derived through a vector approach. A space vector modulation technique is developed for the PWM rectifier in order to generate the desired current vector of the APF. The system generates no acoustic noise and it is implemented with a minimal control hardware structure using the Intel 80196 single-chip microcomputer. Experimental results show that the proposed scheme gives good dynamic and static performance for the APF system.

Despite the advances in medical technology, there are limited therapeutic interventions for cancer. Currently, the main goal of treatment is to remove a tumor completely. However, recent studies have shown that mortality is highly influenced by symptoms such as depression and cachexia, not solely by cancer itself. Depression is caused by psychological stress, and cachexia involves extreme weight loss with skeletal muscle atrophy, which are widely observed in patients with cancer. Although those two appear completely different from each other, they have a common etiology: cytokines. The production of cytokines can lead to depression and cachexia, and it contributes greatly to the increase in mortality rate. A better understanding of depression and cachexia in patients with cancer will help establish efficient treatment strategies.
