This study was conducted to classify quality attributes for quality elements of public service targeting Gochang Jayeonmadang and analyze their impact on resident satisfaction and dissatisfaction by each service quality element by using the Kano model and the customer satisfaction coefficient and dissatisfaction coefficient of Timko(1993). As a result of the study, all 20 quality elements of public service were classified as one-dimensional attributes. Since the Jayeonmadang project restores the damaged natural environment and restores the ecosystem, it is judged that satisfaction is proportionately satisfied as the natural environment has been restored and the ecosystem has been restored. According to Timko (1993)'s analysis of customer satisfaction coefficient, it is believed that the most effective way to improve residents' satisfaction is to carefully establish and implement maintenance plans and to create a good environment to ensure that plants have settled.

The Korean three-way stop contrast (lenis, aspirated, fortis) is currently undergoing a sound change, such that the primary cue distinguishing lenis and aspirated stops is shifting from voice onset time (VOT) to F0. Despite recent discussions of this shift, research on voice quality, traditionally considered an additional cue signaling the contrast, remains sparse. This study investigated the extent to which the associated voice quality [as reflected in the acoustic measurements of H1^*-H2^*, H1^*- A1^*, and cepstral peak prominence (CPP)] contributes to the three-way stop contrast, and how the realization is conditioned by prominence- vs. boundary-induced prosodic strengthening amid the ongoing sound change. Results for 12 native Korean speakers indicate that there was a substantial distinction in voice quality among the three stop categories with the breathiness of the vowel being the greatest after the lenis, intermediate after the aspirated, and least after the fortis stops, indicating the role of voice quality in the maintenance of the three-way stop contrast. Furthermore, prosodic strengthening has different effects on the contrast and contributes to the enhancement of the phonological contrast contingent on whether it is induced by prominence or boundary.

Purpose: This study was designed to measure patient satisfaction and oral health-related quality of life and to assess an association between patients' satisfaction and oral health-related quality of life after implant surgery by using structural equation modeling. Materials and methods: A total of 257 participants who visited 6 dental clinics located in Daegu city for the purpose of implant treatment participated in this study. Six months after completion of implant surgery, the patients' satisfaction and oral health-related quality of life were surveyed. The effect of factors associated with patients' satisfaction such as functions and aesthetics, maintenance and cost on oral health-related quality of life after implant surgery was analyzed using AMOS 4.0. Results: Oral health-related quality of life was improved in all dimensions of OHIP-14 after implant surgery. Functions and aesthetics as well as maintenance had a significant effect on oral health-related quality of life (P<.05), while cost was not a critical factor influencing oral health-related quality of life. Conclusion: High satisfaction with functional aspects and maintenance aspects significantly affected good quality of life. The result of this study supported the fact that education and management for patients after implant therapy were positively related to good quality of life based on a theoretical model.

This article delves into the current status of various packaging technologies, which are currently being applied or are under development for the shelf-life extension and quality improvement of fresh and processed meat products. Traditional packaging methods include vacuum packaging, modified atmosphere packaging, and air-permeable packaging. Recently, innovative packaging methods have been introduced that utilize technologies such as barrier-films, active packaging, nanotechnology, microperforated films, far-infrared radiations, and plasma treatment. All of these packaging methods have their own merits and drawbacks in terms of shelf-life and quality maintenance. A right choice of packaging system for fresh and processed meat products must be made in accordance with the conditions of the raw material, storage, and distribution in the market and household, and while considering the environmental sustainability and consumer's expectations.

The waterproofing systems of concrete bridge deck are installed under the complex circumstances, such as traffic loading, weather, and the condition of the deck concrete. For assuring the effectiveness of waterproofing system, the materials and the construction method and timing ought to be suitably selected with the procedures of waterproofing and the system has to ensure the economical performances. First of all, we discussed whether the quality and performance criteria for highway bridge deck are resonable or not through the investigation of domestic and foreign criteria. The basic properties of waterproofing membranes on market and the performance of waterproofing systems of concrete bridge deck have also been investigated in the view of the damages frequently reported from job site. In this way, the causes and measures of damages, the guidelines of design, construction, quality control, and maintenance, the test methods and criteria of membranes and waterproofing system, are proposed.

This study has been conducted to provide data that contribute to increasing efficiency of 'Private Security', which is cooperated by customer, security companies and the police which carried out 'Public Law Enforcement' and controls security companies. To reach this purpose, we investigated the status of the 'Security Alarm Systems' operated by security service companied in Korea, analyzed arising problems, considered the polices for improving the operational quality. 'Electronic Security Systems' will increase working efficiency in performing 'Private Security'. There can be no two opinions on this matter. Therefore, it can be supposed that the improvement of operational quality of 'Electronic Security System' is an important factor to accomplish security services. 'Security Alarm System' is one of the 'Electronic Security System'. The critical problems in operating 'Security Alarm system' are unnecessary response by false alarm and nuisance alarm. To reduce the problems, it is suggested that security specialist officially licensed should improve security planning, installation and maintenance, and the 'Alarm Verification System' should be introduced with appropriate facilities.

The Sido.Saeol system, a local government information system cost too much for having been designed and developed during last four years but the effectiveness of this system is still open to doubt. Also maintenance cost is still too high and become increasing year by year. To find out the reasons and to suggest how to solve these problems, a service quality of an Sido Saeol system and the public servant's job satisfaction were investigated based on the Delone and McLean's updated IS success Model(2003). To investigate of the effectiveness of the Sido Saeol system, 8 variables are analyzed to test 3 main hypothesis. After all the analysis, we found that Sido.Saeol systems have many aspects to be improved for system use and job satisfaction and have to be revise in the aspects of system qualities.

우리나라의 승강기 기술은 유럽, 미국, 캐나다의 기술표준을 도입함으로써 선진화를 꾀해오고 있으나, 초기의 틀에서 크게 벗어나지 못하고 있을 뿐만 아니라 품질서비스가 아직도 취약한 실정이다. 그 동안 서비스 품질의 정확한 구성요인을 파악하기 위한 연구가 다양하게 이루어져 왔지만, 대부분 서비스품질의 구성요인들 중 기능적 품질에만 국한된 연구가 주류를 이루어 왔으며, 서비스품질 구성요소를 통합한 승강기 유지보수산업에 대한 실증적인 연구는 거의 이루어지지 않은 실정이다. 이에 본 연구에서는 승강기 유지보수산업의 서비스 품질속성에 대한 고유속성과 척도 도출을 통해 경영성과 요인으로서의 고객만족도와 재무 비재무적 성과에 어떠한 영향을 미치는지에 대하여 실증분석하였다. 본 연구의 결과는 우리나라 중소벤처승강기 유지보수 산업의 서비스 품질 제고를 전략의 수립에 기초적인 자료로 활용될 수 있을 것이다.

In this paper, we introduce IEC 60300(Dependability program management) into urban transit system, and propose effective method to apply IEC 60300 to Subway Corporation. The dependability is the collective term used to describe the availability performance and its influencing factors such as reliability performance, maintainability performance and maintenance support performance. A dependability program covers all phases of a system's life cycle from planning to operation and possibly disposal, and is composed of program elements divided into tasks.
