The purpose of this study is to understand the characteristics of intergenerational consumption-oriented attitude and consumer role performance. Major findings are as follows; 1) There is significant difference between the consumption-oriented attitudes of respective generations. The means of New generation are higher than the other generations especially in amusemental consumption-oriented attitude and tenacious consumption-oriented attitude. Baby-boomer generation is more interested in consumption than any other generation and has a rational consumption-oriented attitude. The older generation is passive to consumption and their consumption-oriented attitudes are those of amusement. 2) There is also the significant gap between the consumer role performance of generations. The means of new generation and older generation are higher in consumer role performances than other generations and are especially doing better in the roles of estimator and manager. 3) consumption-oriented attitudes illustrate the variation of consumer role performance and the stronger the rational or tenacious consumption-oriented attitude, the higher the consumer role performance and the higher the rational or tenacious consumption-oriented attitude, and the lower the passive consumption-oriented attitude, the higher the consumer performance. In purchaser and manager role, the more positive the consumption and the higher the rational consumption-oriented attitudes, the better the consumer role performance.

The assignment of exploration on individuals provides challenging work environments, while it generates high levels of complexity. On the other hand, the assignment of exploitation on individuals offers less challenging work environments, while it makes low levels of complexity. Give the characteristics of exploration and exploitation, I argue that the assignments of both exploration and exploitation create the favorable work environments to individuals. Developed hypotheses were tested using a logit regression from a sample of 168 project managers in a R&D center. I found that a manager who experienced exploitation project(s) is positively related to higher performance in exploitation project(s). In addition, a manager who experienced both exploitation and exploration projects are found to be positively associated with higher project performance.

This study classified the study subjects as apartment residents and managers, and conducted the descriptive statistics of research questions related to the effectiveness of the lightweight partition walls and the evacuation space. This study also conducted T-test and Anova to find the different perceptions of the lightweight partition walls and the evacuation space, and the different perceptions of related laws according to the characteristics of the residents and managers. The findings and suggestions were as follows. Firstly, strengthening of the Senior Fire Safety Manager system to prevent the insolvency of fire safety management due to the affiliate. Secondly, implementing enhanced penalties in accordance with not implementing residents education, in order to prevent not smoothly delivering manager trained education to residents. Thirdly, adjusting hands-on training time according to the gender of the managers to supplement women's relatively low perceptions of lightweight partition. Fourthly, mandating evacuation guidance stickers on the evacuation space for residents to remove obstacles in the evacuation space. Finally, establishing regular residents education system in order to improve the awareness of the related laws for residents residing over 16th floors.

The study was conducted with 27 health mangers working in manufacturing industries. The purpose of this study was to analyze the health manager's employment status, health examination, and it's follow. up health management level(about the industrial type). The results are as follows: 1. Characteristics of Manufacturing Industries: The ratio of nurse to employees is 1 : 552.6 and the percentage of physician employed was 51.9% All of the physicians were part time except one. 2. Health Examination and Follow Up ; 1) Periodic screening examinations were provided to 92.39% of the employees. Of these 11.56% required a detailed examination. Follow up on routine cases were done for 51.69%. Follow up on intensive cases were done 13.97%. 2) 62% of all employees working in hazardous conditions(noise, artificial light 74.1%) are required to receive a special health examination bi annually. Of these 96.66% were examined. 11.24% of these employees required a detailed follow up examination. 3. Relevancy between health management level, industrial type, and health manager's status 1) Health clinic operated separately except one case. Nursing activity level :. health diagnosis(0.27) Occupational condition (0.97) Health education(0.81) Health assessment(0.74) Health education level is higher at the industries working in environmental technician(P=0.017).

Leadership is a critical factor for success or failure of an organization. Project managers in construction projects are 'field CEO' so their leadership affects performance of the projects. The objectives of this study is to evaluate the leadership of project managers and to analyse its major characteristics. The LBDQ(Leader Behavior Description Questionnaire) technique was used to evaluate and identify types of leadership of project managers from 'heaven' and 'hell'. Relationships between leadership and performance of the projects were also discussed.

In this paper presents the method of the Optimal Mobile Router Designation (OMRD) using QM(Quality of service Manager) in the nested mobile network. QM is positioned on TLMR (Top Level Mobile Router) in the nested mobile network and manages the information of all MRs in the mobile network. When MN (Mobile Node) moves to a new MR, OMRD (Optimal Mobile Router Designation) selects the candidate MRs group and decides an optimal MR considering the mobile characteristics. OMRD reduces maximally the production of handover and removes the transmission delay of a new call and a handover call resulted from the wireless insufficient resource. Also, it prevents the concentration in a specific MR and maintains equally the load of the whole network.

In this paper, we discuss the design and implementation of a concurrency control manager for a main memory DBMS(MMDBMS). Since an MMDBMS, unlike a disk-based DBMS, performs all of data update or retrieval operations by accessing main memory only, the portion of the cost for concurrency control in the total cost for a data update or retrieval is fairly high. Thus, the development of an efficient concurrency control manager highly accelerates the performance of the entire system. Our concurrency control manager employs the 2-phase locking protocol, and has the following characteristics. First, it adapts the partition, an allocation unit of main memory, as a locking granule, and thus, effectively adjusts the trade-off between the system concurrency and locking cost through the analysis of applications. Second, it enjoys low locking costs by maintaining the lock information directly in the partition itself. Third, it provides the latch as a mechanism for physical consistency of system data. Our latch supports both of the shared and exclusive modes, and maximizes the CPU utilization by combining the Bakery algorithm and Unix semaphore facility. Fourth, for solving the deadlock problem, it periodically examines whether a system is in a deadlock state using lock waiting information. In addition, we discuss various issues arising in development such as mutual exclusion of a transaction table, mutual exclusion of indexes and system catalogs, and realtime application supports.
