  • Some problems are presented that Korean restaurants in jeonju area don't keep ancient fame, taste and tradition. Therefore, this thesis intends to positively analyse the evaluation of Korean restaurants' menu quality to activate Han brand, centering on Jeonju area. The findings of the study are as follows: First, this thesis named the items of analysis menu quality factor, menu quality evaluation factor, Han brand activating factor. Second, it analysed confirmative factor of menu quality evaluation and found that conformity was $x^2=67.143$, df=14, GFI=0.968, AGFI=0.917, RMR=0.056, NFI=0.902, CFI=0.962. It means that the measure of item variables was selected appropriately. Third, it constructed a menu quality evaluation model of Korean restaurants in Jeonju area and verified hypotheses, such as menu quality factors and their influences on menu quality evaluation, menu quality evaluation factors and their influences on activating of Han brand, and menu quality factors and their influences on activating Han brand. It verified the relations, and, as a result, found them to be positive(+) and selected all of the hypotheses.

  • In the resent years, the early evaluation of concrete quality, construction and maintenance has been considered as all is of major concern due to the increase of loading and the degradation of structures related with time. This paper presents evaluation of structural safety performance using measured data of construction, on the basis of a field measurements for the prevention of unreliable concrete works. Measurements analyzed in this paper are early quality condition and performance assessment, serviceability performance by cracks and deflection, rating performance by loading, durability performance by chloride attack and carbonation. Thus, a quantitative assessment model of resistance capacity was developed here to meet the requirement for deteriorated concrete structures. The model focuses on damage mechanical of concrete structures deteriorated by initial damage factors for concrete quality and environment factors such as chloride and carbonation attacks. These results could provide useful information for concrete structures interested in design, construction and maintenance.

  • 개방형 소프트웨어의 사용은 하루가 다르게 증가하고 있는 추세이다. 이렇게 개방형 소프트웨어의 사용이 증가함에도 불구하고 개방형 소프트웨어의 품질에 관한 문제의 중요성은 충분히 고려되지 못하고 있다. 그리고 기존 개방형 소프트웨어의 평가모델로 사용되고 있는 기존 평가모델을 살펴보면 정량화 수준이 미흡하고 평가자의 주관이 개입될 수 있는 소지가 있고 명확한 평가방법이 공개되지 않아 실질적으로 적용하기에 많은 문제점이 있다. 따라서 본 논문에서는 평가자에 의해 좌우되지 않는 일관성 있는 정량화된 기준과 평가정보 획득의 자동화를 고려한 신속한 평가 가능성 제고 할 수 있는 평가기준을 구축하였다. 구축된 품질평가 모델은 개방형 소프트웨어의 품질을 평가하고 향상시키는데 중요한 역할을 하게 된다.

  • Purpose: This paper provides a method to identify cost-effective standards by analyzing the relationships between certified company and standards. It also aims to provide a evaluation model to establish a certification portfolio strategy of institutions. Methods: By analysing the networks of certified company and certification standards, this paper developed an evaluation model of standards. The evaluation model uses an index(Certificated Standard Evaluation Index; CSEI) to assess the value of standards. Results: To verify the applicability of the evaluation model, the proposed model and the CSEL index have been applied to certification standards of Korean Standard Association. The results show that the evaluation model can effectively identify potential customers and thereby establish a certification portfolio strategy. Conclusion: The main contribution of this study is a provision of a new approach to certification portfolio strategy by evaluating the value of standards. The proposed model is expected to provide implications for the certification portfolio strategy.

  • We propose a new method that specifies objective image quality factors by evaluating an image quality measurement model using random images. In other words, No-Reference variables are used to evaluate the quality of an original image without using any reference for comparison. 1000 portrait images were collected from a web gallery with votes constituting over 30 recommendation values. The bottom-up data collecting process was used to calculate the following image quality factors: total range, average, standard deviation, normalized distribution, z-score, preference percentage. A final grade is awarded out of 100 points, and this method ranks and grades the final estimated image quality preference in terms of total image quality factors. The results of the proposed image quality evaluation model consist of the specific dynamic range, skin tone R, G, B, L, A, B, and RSC contrast. We can present the total for the expected preference points as the average of the objective image qualities. Our proposed image quality evaluation model can measure the preferences for an actual image using a statistical analysis. The results indicate that this is a practical image quality measurement model that can extract a subject's preferred image quality.

  • RFID applied in many area. I think that RFID enlarge for our life more and more. The application technology of RFID change the Mobile RFID using mobile phone and PDF etc. I think, Mobile RFID enlarge application technology gradually. In this paper, we propose the quality measurement metrics for mobile RFID middleware. I propose the quality testing model for interoperability and security of mobile RFID middleware. We examine the international standard for mobile RFID and software testing. In this paper, I proposed the evaluation model of mobile RFID middleware on the basis of international standard ISO/IEC 9126-2 and ISO/IEC 25000 series.

  • One of the important components of this administrative reform is customer satisfaction. Every public enterprises introduced the Service Charter and Korean government took Customer satisfaction as the key index of public sector performance assessment. Most public enterprises introduced customer satisfaction management in an attempt to improve the quality of customer service. The government granted high incentives to excellent business innovative enterprises and developed additional indices, which are related to CS. From now on, every Korean enterprises must embody feasible customer satisfaction management and improve the quality of customer service In this research, we proposed a quality evaluation standard model which is suitable for the public enterprise based on the Service Quality Criteria, and examined the model. A 7-Point Likert Scale was used based on the five categories within the Service Quality: responsiveness, convenience, tangibility, sympathy and reliability, we analysed the validity and causal relationship among the factors within the model.

  • Rising healthcare cost is a global phenomenon that justifies governments' introduction of 'incentive regulation' plan for the improvement of hospital efficiency. A number of previous studies tried to evaluate the efficiency of healthcare organization by using Data Envelopment Analysis(DEA), a common efficiency benchmarking method. However, there is a concern that this kind of efficiency evaluation could induce "quantity-quality trade-off". Moreover, as quality aspect is especially important in terms of 'effectiveness' of health care, it should be considered in efficiency evaluation of healthcare organization. A number of different models were tried so far to incorporate quality aspect into DEA, however, none is universally recognized as a standard. Thus, in this study, previous quality-incorporating DEA models were categorized into 6 types according to the way of incorporating quality aspect, and strengths and limitations of each type were reviewed with a set of artificial data as an example. Based on this review, a new quality-incorporating efficiency evaluation model, named Quality-adjusted output DEA(QAO-DEA), was suggested. As an exploratory empirical analysis, technical efficiency of human resource were measured with different quality-incorporating DEA models, using 2004 data from National University Hospitals. In conclusion, Quality-adjusted output DEA(QAO-DEA) model seems to be one of the most desirable alternatives to incorporate quality aspect in efficiency evaluation of hospital, and deserves the consideration as a policy tool to induce simultaneous improvement of both efficiency and quality.
