The importance of project performance management as an alternative for solving problems is rising, which are followed by the difficulties of managing construction project in the construction industry. This research classifies and applies the potential improvement made by the construction practitioners. In order to apply influential factors for success on the construction project, the research identifies the relationship between the factors and performance management practices. In addition, in order to predict the results reflecting the project characteristics which are un-improvable by the construction managers in the initial stage of construction, the effect of project characteristics to the identified management practices have been drawn by performance area. Finally, in order to improve the predicted performance, this research provides a framework in setting valid best practices according to the performance areas through a statistical analysis between the best practices and project characteristics through the industry survey.

The present study was undertaken to examine the relationship between time required for each step in the treatment process for pedodontic patients. and age of the patients, and experience of special training for pedodontics and career of dental practitioners. Information of these matters was gained from 580 questionnaires collected from 69 practitioners (62 male and 7 female). The questionnaires included questions about the patients' sex(303 male and 207 female) and age. The patients were categorized into 5 different age groups : Group 1, age $1{\sim}3$-year ; Group 2, $4{\sim}6$-year ; Group 3, $7{\sim}9$-year ; Group 4, $10{\sim}12$-year ; Group 5, $13{\sim}15$-year. The questions about the dental practitioners were the years of experience in private dental practice(5 years or more than 5 years) and whether or not they took the special training for pedodontics in the authorized institutes. The practitioners were asked to answer the questions about Frankl scale of the patients' behavior during the treatment, and time spent for managing the patients to be subjected to local anesthetic injection (the first behavior control), time for the injection, and time for the subsequent treatment. The results obtained by analyzing the information collected from the questionnaires were as follows : 1. The younger the patients, the lower the Frankl scale was counted at the time of the first behavior control, injection, and the subsequent treatment(p<0.001). 2. The lowest Frankl scale was scored during the injection regardless of the age of the patients. 3. Time for management and treatment was decreased in the order of age Groups 1 and 2< Group 3 < Groups 4 and 5. 4. The patients showed a more positive frankl scale in response to the treatment performed by those who were more-experienced in dental practice as compared with those were less-experienced. 5. Pedodontic training experience of the practitioners did not appear to influence the patients with respect to the treatment time and Frankl scale.

This study empirically investigates the antecedents and outcomes of choice satisfaction in the context of choosing and using the broadband Internet network services. Hypotheses are tested with regression models analyzing a survey data of 481 consumers of the broadband Internet network services in Korea. Our results show that choice satisfaction is affected by choice contexts while service satisfaction is not. Choice satisfaction is as important as service satisfaction for formation of switching intentions whereas it is less important for formation of recommendation intentions. Also, consumers characteristics are reported for those whose service satisfaction and choice satisfaction are not consistent. Choice satisfaction is a distinctive concept different from service satisfaction. Marketers can make consumers more satisfied not only managing delivery of services but also by managing their choice contexts. That will increase the loyalty of their consumers. This study finds unique determinants of choice satisfaction. Further studies are needed to clarify boundary conditions regarding the effects of choice contexts on choice satisfaction.

The purpose of this research was to find out attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Pusan, Daegu, and Daejeon. The survey had been conducted in 414 respondents with questionnaire during May to June, 2003. Frequency, Crosstabs, T-test and ANOVA were obtained from the collected data using SPSS/WIN program. The results of this study were as follows. First, most respondents were preparing toward work in later life somewhat actively and the level of preparation differed by individual characteristics. Those who have higher level of education and subjective economic power were more active. The most preferred work item in later life were raising animals and plants, managing institution and training center and running shop. Those who have higher level of education and asset preferred managing institution and training center. Second, nearly three fourths of middle-aged have chosen leisure activities in consideration of later life and two thirds were preparing economically for leisure in later life. They have strong intention to participate in the leisure activity in later life and they also wanted to take part in various kinds of leisure activities. Those who have higher levels of education, subjective economic power, health and asset were more active in preparing leisure in later life. Third, over two thirds preferred to live and work in later life together with others rather than to live and work alone. Nearly half had intention to move to the senior community where work was available. The intention to move were differed by attitudes to work and leisure in later life. Those who were active in work and leisure in later life presented higher intention to move to senior community available work.

Collecting and managing the sensor information through the Internet is critical to effectively manage and utilize the sensor information. The interworking technique of the sensor network and internet is required to realize the desirable condition for managing and utilizing the sensor information. Among many interworking techniques, the translation technique using the gateway had been widely studied. However, the technique which mounts IP-based Internet protocols directly on the sensor node is getting more attention recently. Particularly, IPv6 is suitable for the communication protocol for the sensor network, because its features, such as abundant address space or address auto-configuration, are well matched with the sensor network. In this paper, we design the tiny UDP/IPv6 protocol functions which are suitable for the sensor network environment, and we implemented the functions with TinyOS based nesC. After we examined the simulation results of by using TOSSIM and TinyViz, we carried out the experimental performance evaluation for the program by mounting the tiny UDP/IPv6 on the sensor node (Mote).

As science and technology infiltrates every aspects of modern society in terms of economic and social growth and development, funding for research and development (R&D) is growing rapidly. Republic of Korea is not an exception in this trend and the R&D funding in Korea has been grown about 10% every year, recently. However, as the scope and size of funding grows exponentially, need for monitoring and managing these R&D projects becoming more and more imminent. Though different types of project management systems were developed by a variety of agencies and departments and used in monitoring and managing, these systems were developed as standalone silo type systems. These systems are not connected to each other while the same researchers may involved in different projects across agencies and department. Also, these management systems are not linked to the banking systems in which real transactions of funding occurs, such as cost reimbursement and financial audit of each R&D accounts. Historically, a few fraud and malappropriation cases were found and indicted. However, as the number of these incidents grows along with the growth of R&D funding, a large scale integration/linking of project management systems and banking systems. Realizing the importance of systems integration among agencies as well as with the banking systems, situational requirements analyses were conducted concerning the current state of R&D management system. As a results, a Real-time Case Management System (RCMS) was proposed as a solution to current problems. In this paper, the collected systems requirements were documents with analyses of the situation, the architecture of the integrated systems with more user-friendly technological alternatives. This large scale linkage requires interface standardization as well as modularization of interfaces. Proposed systems architecture is introduced here with technical details of Jex Framework used,, followed by resulting technical and economic performance of the Realtime Cashflow Management System (RCMS).

This study is designed to evaluate the service quality of public libraries according to managing entities by LibQUAL+ and to devise ways to improve problems based on comparison and analysis of the differences in the service qualities. To achieve this, four public libraries in Seoul according to the managing entities were investigated. They consisted of libraries of public corporations, cultural centers, foundations and universities. Minimum service quality level, desired service quality level and perceived service quality was analyzed based on nine-point Lickertis scale. A survey was employed and consisted of twenty-two items. The results showed that current level of service met the minimum level, yet failed to reach their desired service level. The study suggested that public libraries contracting out to private sector need to actively apply users' demands and the changing environment of libraries, and continue to strive to provide public library users with high quality service through efforts of evaluating and improving the services for their users.

This study was performed to assess socioeconomic status and physical health status of middle-aged men ($40's{\sim}60's$) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthro-pometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p = 0.000) and most of them decreased according to age in educational levels (p =0.000) and family income (p =0.000), and prevalence of chronic diseases (p =0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in oder males (p =0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%. 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p =0.015). Waist-hip ratio (WHR) increased in older males (p = 0.028) and females (p= 0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.

The Waikato River is New Zealand's longest River, though relatively small on international scales. It drains the central North Island and has New Zealand's largest lake (Lake Taupo) at its headwaters. The upper reaches have sustained flows fed by large aquifers which are recharged by rainfall events providing relatively constant river flows, whereas the lower reaches respond more directly to rainfall events having more peaky flows after rainfall and extreme low flows during dry periods. Consumptive allocation from the river is relatively low with only about 3% of the mean annual flow being allocated. However, more than seven times the river's flow is allocated for non-consumptive purposes before discharging to the Tasman Sea. The majority of this non-consumptive allocation is for hydro power generation and as cooling water at both thermal and geothermal power stations which produce up to 25% of New Zealand's electricity. The upper half of the river has been heavily modified with the construction of eight dams for power generation. This has resulted in a succession of cascading dams replacing the previously uncontrolled river. The Waikato River also provides drinking water for Auckland City (NZ's largest city) and Hamilton City (NZ's 4th largest city). In recent years there has also been considerable growth in water requirements for pasture irrigation to support the intensification of dairy farming in the catchment. Operators of the power stations are concerned that any further consumptive allocation will further reduce their ability to generate electricity. The Waikato Regional Council, who is charged with managing the river and allocation of water, has recently set new rules for managing the conflicting allocation demands on the Waikato River. This has resulted in an end to further allocation of water where it results in a loss of water for electricity generation from renewable resources (fresh water and geothermal water). The exception to this is the prioritisation of water for municipal supplies ahead of other consumptive uses such as industries and irrigators.

Using hybrid channel affords the benefits of achieving control through the direct channel and achieving flexibility through the indirect channel. However, using a hybrid channel also poses special challenges to a manufacturer, including the problem of managing multiple channel members with disparate goals and priorities. The purpose of this study is to enhance our understanding on the management of hybrid channel. We study marketing channels for fashion apparel to examine governance challenges and solutions of a hybrid channel. We have two objectives to fulfill that purpose. First, we aim to tie two largely separate research streams of salesforce management and marketing channel management together by examining both intrafrim governance and interfirm governance issues under one conceptual framework. Second, we aim to lay a ground work for rigorous further research on this topic by tying two major theoretical approaches of governance together under one conceptual framework. Our predictions were tested with data from the survey of apparel manufacturers and retailers. The analysis results support the predictions moderately.
