Every service firm must find ways to attract new customers, retain existing customers, and remain competitive and profitable. As competition increases, delivering better service becomes more important. Service quality is considered as a vital aspect for the success of the firms. Restaurant cannot be separated from the service quality they have to deliver. The development of restaurant is supported with the reputation of the country where the food comes from. Recently, one of the most trending topic is Korean wave which affects the Korean cuisine. A fuzzy AHP was employed to evaluate the service quality. It is more preferable than traditional AHP which is criticized for its inability to handle the uncertainty of the decision maker's perception. Six attributes are used to evaluate five Korean restaurants in Semarang, Indonesia. The result shows that innovation is the most important attribute. It seems that decision makers viewed the food variation and new method service as main factors that the restaurants have to manage. This finding can provide the managers with valuable insights into the attribute that reflects customers' perceptions; also to position their service based on their competitors. Validating the scale in other culture-based restaurants is an interesting area to be pursued.

The purpose of this study was to propose an efficient management plan for purchased land considering the hydrological, watershed characteristics and ecological functions of the target land and surrounding area based on the result of monitoring the water quality improvement effect obtained by purchasing the land in the watershed area in the Geum river system. For this purpose, this study investigated through literature review, and examined ways to apply them to this research by deriving implications from a comprehensive analysis of previous research cases. After that, the components of assessment were derived to evaluate the ecological function of the purchase land, and the ecological function evaluation model for each land and area was proposed. In order to select purchase and restoration priorities of the land, this study analyzed the ecological status of the purchased land in main watersheds and tributaries using Arc GIS ver 10.1. Through this, a process to select restoration priorities was developed. And this study constructed the integrated management process with proposing a mid - to long - term plan by integrating the purchased land valuation and restoration priority selection process. Based on this process, this study suggested an effective management plan for purchased land through the integrated ecological management system of lands purchased. It can be used systematically in appraisal valuation, land purchase system, restoration project, and follow-up management of land purchase.

One of the widely accepted methods for evaluating the interior sound quality of automobiles is Articulation Index(AI). The AI actually measures the articulation level of the sound in the vehicle cabin as passengers talk to one another. In this study, the effect of two different absorption materials inside the cabin on AI has been investigated by ray-tracing method : one is firewall, the other is celling. It turns out that the back seat location is found to be strongly dependent on the type of absorption materials treated at the celling, since the sound absorbing area is different due to the location and the firewall is situated in the "Reverberation Radius". The proposed methdo could be used to improve the sound quality of automobiles at the design stge.sign stge.

This paper investigates and selects the areas that need to be improved in R&D and production management of small and medium size companies. The study on the capability of R&D and production management shows that the areas for evaluating of the R&D and production management levels are composed of 8 elements : R&D resource, R&D support and experience, long-term operations strategy, intermediate range planning, short-term planning, subcontractor management, logistics and inventory management, and quality management. The investigation of the gap between the importance of the areas and the capability of SMEs shows that the most important things are to consolidate supply chain, to improve product and process competitiveness using quality improvement, and to enhance production management through sophisticated short-term planning. The detailed analysis also shows that the areas that need to be improved depend on the size and sales of the company.

FM screening has been praised for its apparent resolution advantage over conventional AM screening. FM screening is also known for its criticalness of film output and difficulties in the proofing stage because of the microdot formation. However, FM screening is not a well understood process from press performance point of view. This study was carried out for the purposed of introduction the availability of hifi-offset printing to domestic printing industries and evaluating the print qualities between 300pli AM screen and FM screen with the equivalent sized microdots to 4-5% dot area of the 300lpi AM screen, together with comparing with the 175lpi AM screen representing a conventional printing. Solid density, dot gain, color gamut and some other quality properties were measured and discussed.

This study surveys the surface water environment in Southwest sea areas of Vietnam in order to evaluate the current environment. It collects and analyzes experimental results of programs, scientific subjects, and international projects relevant to ecological areas and coastlines of Kien Giang province. The methods analyzed and discussed by specialists are evaluated according to pollution coefficients established by the World Health Organization (WHO), sampling methods, and case study analyses. Comparison between the scale of pollution levels and the surface water quality in experimental areas of Long Xuyen Quadrangle shows a light-moderate pollution level. In Ca Mau Peninsula, the surface water source is only slightly polluted. Sea areas and islands are also light-moderately polluted. Computing results from water quality indices (WQI) show the level of pollution in experimental sites. Activities such as constructing infrastructures for tourism, exploiting minerals, and increasing population accelerate environmental pollution by deteriorating inherently sensitive ecosystems like corals, sea grass, mangrove swamps, and Melaleuca forests. Surveying and evaluating the present situation of surface water are fundamental solutions for environmental protection in the Southwest sea areas of Vietnam.

This paper describes a affine transform coding which is reducing long time to take on image encoding by using scaling method and limited search area technique. For evaluating its performance, the proposed algorithm compare with Jacquin's method using traditional affine transform coding methods. Simulation results, the proposed algorithm considerably reduces encoding time by using scaling method and limited search area method. Also, the proposed algorithm provides much shorter encoding time with a little degradation of the decoded image quality than Jacquin's method.

The quality of apartment houses has been gradually upgraded. However the changes in demographic composition of residents such as seniors, disabled persons, and etc. have not been considered in the process of planning. If apartment houses are designed on the base of the concept of universal design, their residents could live as long as they want to live in. This study evaluates the Korean standard-sized apartment housing units and the common spaces of those apartment buildings, and it's outdoor environments from the perspective of universal design. The observation and measuring was conducted with the questionnaire survey with 100 residents living in those housing units. 60 items were designed for evaluating them in relation to the principles of universal design. The results are as follows : 1) In general, the principles of universal design were relatively applied to the apartment houses. However their application needs to be broadened. 2) The number of parking lots needs to be increased and the width of individual parking lot to be increased. Also, the location of gazebo and senior center needs to be placed in easily accessible areas. 3) The shape, color, finishes of the ramp and the entrance area of the apartment building and housing unit should be made more homelike. Also, the entrance area of apartment building and housing unit needs to be made large enough for residents themselves and meeting with neighbors. 4) Among all of the rooms in a housing unit, bathroom should be improved immediately. Also, the width of doors should be at least 80cm wide and the floor should be made even.

The coast of Incheon reaches Incheon itself, Gimpo, Siheung, and Ansan of Gyunggi-do. Because this area has been seriously polluted, the Ministry of Oceans and Fisheries has established the Incheon Special Area Management Plan (SAMP) to preserve sea water quality as a marine environment asset. However, there is concern that actions taken in this area may change the surrounding marine ecology, being effected by farms, via a river that flows from waste lands, abandoned fishing activities and fishing nets, etc. Given this background, this study estimates the value of SAMP sea water quality using a choice experiment (CE). A CE survey of 1,000 households was undertaken, investigating trade-offs involving price and four attributes for selecting a preferred alternative to obtain a marginal willingness to pay (MWTP) estimate for each attribute. The estimation results showed that MWTP for a 1 %p improvement in sea water quality, the diversity of fauna species, the diversity of flora species, and a 1 %p reduction in marine litter as a result of conserving Incheon coastal sea water quality are estimated to be KRW 75, 135, 309 and 72 per household per year, respectively. All estimation results were statistically significant at the 1 % level. These findings can provide policy makers with useful information for evaluating and planning marine environmental management policies.

The rapid change in almost every area of science at the turn of the 21s1 century have also affected libraries and information centers. Whatever the change, from the library users' perspective, the functions provided by the library, is perceived as "service" and the satisfaction of the users can only be measured by the quality of the service. The study adopted the SERVQUAL model and five factors of SERVQUAL. Tangibles, Reliability, Responsiveness, Assurance. and Empathy are used as parameter values. In measuring the parameter variable, both the users' expectations and their perceived service level were measured. The difference between the expectations and the perceived level was used as users' assessment of service quality. According to the results. all but re-investment dependence level among the five SERVQUAL levels, were linked in one way or another.r another.
