VE, rather than just cost reduction tool, have established as a value enhancement tool of the construction industry. Value improvement types of VE proposal can show the effect of VE activities, also acts as an important element in which the owner adopts a proposal and confirms the results of the VE activities. However, problems in the process of quantification for VE proposal and ambiguous standards in classification of value improvement types is need to be supplemented. Accordingly, This study suggests the plan for establishing of numerical range criteria for classification of value improvement types of VE proposal. Implementing this plan will be able to improve the reliability and availability for VE activities.

The purpose of this study was to evaluate the effects of perceived value on the satisfaction and revisit intention of green tea farm visitors. The sample was obtained during the three month period from May 19th, 2006 to May 21st, 2006, and out of 800 copies of questionnaire, 597 copies responded with sincerity were analyzed. First, the perceived value of visitors in green tea farms seemed to have effective relations with satisfaction. Second, the perceived value of visitors in green tea farms seemed to have effective relations with revisit intention. Empirical evidence is obtained for both regional economy and industry and the development of tourism products. Specially, findings from this study suggest that perceived value are strong predictors of revisit intention to green tea farms in Hadong-gun. Several implications for the research result and actual application practices are discussed.

The purpose of this study is to measure the effects of behavioral intention. A total of 273 questionnaires were completed. The equation model was used to measure the causal effect. The results demonstrated that the confirmatory factor analysis model provided an excellent model fit. The comprehensive model yielded a significantly better fit to the data and accounted for a greater share of the variance in behavioral intentions than the five competing models. The effects of satisfaction, perceived value and service quality on behavioral intention were statistically significant. As expected, service quality and value had significant effects on satisfaction. Service quality and perceived sacrifice had significant effects on value. Moreover, service quality and value perceptions had an indirect influence on behavioral intentions. The overall findings offer strong empirical support for the intuitive notion that improving service quality can increase favorable behavioral intentions and decrease unfavorable intentions.

As the mobile Internet spreads around the globe, a cross-national difference in the use of mobile services has become an important issue. The goal of this study is to propose and verity cross-national differences in the effect of each value-type on user satisfaction with the mobile Internet. We propose an analytic framework of four different types of value and apply this model to the value structures of mobile Internet users in two different countries. Large-scale online surveys were conducted in Korea and Hong Kong simultaneously with the same questionnaire. Results show that the relationships between the value components and user satisfaction varied between the two countries.

The central issue in this particular research is the seemingly inadequate achievement of optimum performance in the construction process, either with respect to value for money for the client and the entire construction supply chain or value in terms of the utility derived from built assets in spite of efforts by government and governmental bodies such as the Construction Industry Development Board (cidb) to increase industry performance. Therefore, based upon an extensive review of related literature, the paper reports on effects and causes of non-value adding activities in the construction industry in general, and South African construction in particular. The research findings indicate that activities that can be referred to as non-value activities are not only prevalent, but they can also be held responsible for performance related issues in terms of cost, time, quality and health and safety (H&S) in construction; and the exploration of pluralism in the research methodology may result in a robust model based upon the system dynamics approach.

The purpose of this study was to find out the clothing values and meanings by material values. The researcher used the scales of Richins & Dawson (1992) for Materialism Scale. The scales of Prentice (1987) and Ricllins (1994a, 1994b) for privateand public meanings of clothing. The scales of Prentice (1987) and Richins (1994a, 1994b) for importance clothes of private and public meanings.. The scales of Creekmore (1968) for clothing values. The subjects of this study were 154 girl students in the university. The research materials was analyzed by Frequency, MANOVA and Scheffe test The results of this study were as follows; 1) Higher group of material values had an orientation that emphasizes enjoyment values of clothing in private moaning and seems expensive of clothing in public meaning. 2) All group set a high value on both suits and jeans in clothing of private meanie that meant both interpersonal and enjoyment values and put much worth on both suits and mustang that concerned both costly and brand. 3) Higher group had significantly difference in aesthetic value and political value, and lower had significantly differene ineconomic value and theoretical value.

A method to measure heating value of natural gas using sound velocity and thermal conductivity is proposed to solve the low heating value issues of imported natural gas in South Korea. Natural gas generally consists of methane, butane, ethane, and inert gases. Heating value changes as the gas material properties, such as density, wobbe index, etc., varies. It is highly important to measure heating values of natural gases accurately because measuring the heating value depends on the given natural gases' components. Therefore, sound velocity and thermal conductivity is measured to estimate indirectly heating value of Natural gas with their changed components.

There are many application areas of sensor networks, such as surveillance, hospital monitoring, and home network. These are dependent on the secure operation of networks, and will have serious outcome if the networks is injured. An adversary can inject false data into the network through the compromising node. Ye et al. proposed a statistical en-route filtering scheme (SEF) to detect such false data during forwarding process. In this scheme, it is important that the choice of the threshold value since it trades off security and overhead. This paper presents an adaptive threshold value determining method in the SEF using fuzzy logic. The fuzzy logic determines a security distance value by considering the situation of the network. The Sensor network is divided into several areas by the security distance value, it can each area to uses the different threshold value. The fuzzy based threshold value can reduce the energy consumption in transmitting.

When performing steering by an autopilot (automatic steering gear), a sensitivity adjustment is mainly determined by P value and D value. These values differ in the optimal combination by model of ship and external forces. This research was carried out simulation case studies and examined movement of Pure Car Carrier, which easily received ship by wind pressure influence in low speed We investigated the relation of horizontal migration(transfer) of ship's body and P-D value. Based on it, four parameters of P-D at approaching berth could be suggested Hence there were suggestions of parameters; Distance to maximum lee point, Time to maximum lee point, Time to return to original course and Time to 300th second. The correlation of these parameters and P-D value were also considered. As a result, we think that this index, like formulated P-D, leads to an easy and safe navigation by utilizing these indices.
