This study is to check up weather a brand of accreditation program for healthcare organizations recognized by the consumers as users of the healthcare organizations has effects for healthcare organizations' brand trust, attitude, and loyalty. This study suggests the hypothesis that a brand value of accreditation program for healthcare organizations gives the positive effect for the brand trust, attitude and loyalty, and that the brand trust and attitude of healthcare organizations which gain a brand of accreditation program for healthcare organizations cause the brand loyalty. To verify the hypothesis, this study made a questionnaire by using a measuring instrument for the brand value, trust, attitude and loyalty which come from the former study. This study carried out an analyzing method such as frequency analysis, reliability analysis, confirmed factor analysis and structural equation model to verify the hypothesis. From hypothesis verification, emotional and social brand values of accreditation program for healthcare organizations gave a positive effect to the brand trust and attitude on healthcare organizations. Its functional value did not give an effect to a brand attitude but gave a positive effect to healthcare organizations' brand loyalty. Emotional and social brand values of accreditation program for healthcare organizations did not give an effect to the brand loyalty. The brand trust and attitude of the healthcare organizations which gained accreditation program for healthcare organizations gave a positive effect to the brand loyalty on healthcare organizations.

In this thesis, we created a Fuzzy rule in a Fuzzy logic that are fuzzy logic which is composed of linguistic rules and Fuzzy inference engine for effective traffic control in ATM networks. The parameters of the Fuzzy rules are adapted to minimize the given performance index in both cases. In other words, the difuzzification value controls the service rate in the server to total traffic arrival ratio and buffer occupancy ratio using fuzzy set theory for traffic connected after reasoning. Also, show experiment result about rule by MATLAB6.5 and on-line bulid-up to verify validity of created Fuzzy rule. As a result, we can verify that service ratio in server is efficiently controlled by the total traffic arrival ratio and buffer occupancy ratio.

In this paper, an efficient hardware architecture of Lempel-Ziv compressor for real time data compression is proposed. The accumulated shift operations in the Lempel-Ziv algorithm are the major problem, because many shift operations are needed to prepare a dictionary buffer and matching symbols. A new efficient architecture for the fast processing of Lempel-Ziv algorithm is presented in this paper. In this architecture, the optimization technique for dictionary size, a new comparing method of multi symbol and a rotational FIFO structure are used to control shift operations easily. For the functional verification, this architecture was modeled by C programming language, and its operation was verified by running on commercial DSP processor. Also, the design of overall architecture in VHDL was synthesized on commercial FPGA chip. The result of critical path analysis shows that this architecture runs well at the input bit rate of 256kbps with 33MHz clock frequency.

Objectives: The objective of this study was to test the feasibility and acceptability of a new workers' health surveillance (WHS) for fire fighters in a Dutch pilot-implementation project. Methods: In three fire departments, between November 2007 and February 2009, feasibility was tested with respect to i) worker intent to change health and behavior; ii) the quality of instructions for testing teams; iii) the planned procedure in the field; and iv) future WHS organisation. Acceptability involved i) satisfaction with WHS and ii) verification of the job-specificity of the content of two physical tests of WHS. Fire fighters were surveyed after completing WHS, three testing teams were interviewed, and the content of the two tests was studied by experts. Results: Feasibility: nearly all of the 275 fire fighters intended to improve their health when recommended by the occupational physician. The testing teams found the instructions to be clear, and they were mostly positive about the organisation of WHS. Acceptability: the fire fighters rated WHS at eight points (out of a maximum of ten). The experts also reached a consensus about the optimal job-specific content of the future functional physical tests. Conclusion: Overall, it is feasible and acceptable to implement WHS in a definitive form in the Dutch fire-fighting sector.

In this paper, we implemented a VLC(Visible Light Communication) system capable of transmitting/receiving data on a 30MHz clock based on On/Off keying modulation/demodulation. The data rate of the implemented system can be verified by functional verification of VLC channel composed of LED/photodiode driver and VLC transmitting/receiving signal of Tx/Rx platform. But, In the experimental results with the VLC transmitting/receiving for combined module, the maximum transmission rate was measured at 15 MHz. Therefore, we describe the problems that can occur when implement the VLC system using the LED module with output power of 15W or more and propose ways to improve it.

This paper describes an optimal design of electric snow melting mat on vulnerable walk zone. In order to design an optimal electric power of snow melting mat and protect pedestrians with a nonslip mat, with considering protection of environmental pollution from abusing of the de-icing salts added calcium chloride. We analyzed nine snow melting mats through verification experiment in the condition of $-5^{\circ}C$, depending on three different kinds of heating material, electric heating cable, carbon heating film and carbon textile film. As a consequence, the $150W/m^2$ carbon textile film mat for snow melting was identified as an optimal power input and functional performance for pedestrians' safety on vulnerable walk zone. It is expected that the $150W/m^2$ carbon textile film mat would be useful to reduce slip down accidents by human error.

Since the beginning of the twentieth century, the progressive and rapid spread of reinforced concrete (RC) has led to the adoption of mixed masonry-RC solutions, such as the confined masonry. However, together with structures conceived with a definite role for earthquake behaviour, the spreading of RC technology has caused the birth of mixed solutions inspired more by functional aspects than by structural ones, such as: internal masonry walls replaced by RC frames, RC walls inserted to build staircases or raising made from RC frames. Usually, since these interventions rise from a spontaneous build-up, any capacity design or ductility concepts are neglected being designed only to bear vertical loads: thus, the vulnerability assessment of this class becomes crucial. To investigate the non-linear seismic response of these structures, suitable models and effective numerical tools are needed. Among the various modelling approaches proposed in the literature and codes, the authors focus their attention on the equivalent frame model. After a brief description of the adopted model and its numerical validation, the authors aim to point out some specific peculiarities of the seismic response of mixed masonry-RC structures and their repercussions on safety verification procedures (referring in particular way to the non-linear static ones). In particular, the results of non-linear static analyses performed parametrically to various configurations representative of different interventions are discussed.

Purpose - This study aimed to identify the impact of consumers' perception of the value of discount store PB products on brand loyalty and repurchase intention and simultaneously check whether consumers showed a different position depending on gender difference and age. Research design, data, and methodology - For data collection, total of 174 valid copies of questionnaire were obtained for analysis. And simple regression, multiple regression and hierarchical moderated regression analysis was conducted for hypothesis verification and implication Results - It was found that functional, social and emotional value perceived by consumers had a positive impact on brand loyalty and repurchase intention. And it was found that consumers who were in a relatively lower age group were positive, in the relation between emotional value and repurchase intention only. Conclusions - It was suggested that consumers accept discount store PB products positively overall. Therefore, discount stores must not only need to develop their strengths in various parts of PB product beyond consumer's positive perception but also make efforts to raise the social awareness of the use of PB products. And they have to promote consumer decision making by concentrating on emotional factors take a different approach to consumers in a higher age group.

In a software development process, it is necessary to have a method which verifies and satisfies users' requirements in their point of view. This allows the system developer to design a high qualify software system and have it developed and used in an effective way since users' requirements have well been shown through it. In this paper, we propose the RV-UI model system that can verify users' requirements a step ahead of system implementation step. This RV-UI model system has standardized user interface which is in practical use into functional model for each process and it is designed to satisfy users' requirements and manage configuration of them through the interface which has the Kano model.

Purpose: The main objective of this paper is to propose an RD method by developing a neural network (NN)-based estimation approach in order to provide an alternative aspect of response surface methodology (RSM). Methods: A specific modeling procedure for integrating NN principles into response function estimations is identified in order to estimate functional relationships between input factors and output responses. Finally, a comparative study based on simulation is performed as verification purposes. Results: This simulation study demonstrates that the proposed NN-based RD method provides better optimal solutions than RSM. Conclusion: The proposed NN-based RD approach can be a potential alternative method to utilize many RD problems in competitive manufacturing nowadays.
