  • Supply chain in service sector has been established on the premise that firms need to manage their process uncertainties to satisfy customers in an efficient manner. Information sharing and synchronization play key roles in minimize uncertainties from their involved supply chain. The duality of customers being inputs providers as well as consumers, differentiates service supply chains from manufacturing and is a challenging issue to traditional supply chain management. The service supply chain is a structured network which should be managed with supply chain theory and principles. Various key operations need to be carried out through a highly integrated and collaborated service supply chain and supporting information hub. The purpose of this paper is to present the issues and key components in the service supply chain, where the repetitive service is provided along the value chain, such as tourism, restaurant, mega-sized hospital supply chain.

  • In the case of an extraction in the maxillary anterior region, immediate placement of implant-supported fixed prosthesis can be considered as a treatment option. Fewer surgical operations, reduced treatment time, and optimal availability of existing bone are obvious advantages of the method; however, when applied in the continuous maxillary anterior region, inter-implant distance must be carefully considered, as well as accurate diagnosis and treatment planning for predictable outcome. In this case report, immediate placement of two implants in the continuous maxillary anterior along with bone graft following the extraction of root rests, and the restoration of provisional and implant-supported fixed prosthesis on a 63-year-old patient had resulted in both esthetically and functionally satisfactory clinical outcomes.

  • Quality function deployment (QFD) is a widely adopted customer-oriented product development methodology by translating customer requirements (CRs) into technical attributes (TAs), and subsequently into parts characteristics, process plans, and manufacturing operations. A main activity in QFD planning process is the determination of the target levels of TAs of a product so as to achieve a high level of customer satisfaction using the data or information included in the houses of quality (HoQ). Gathering the information or data for a HoQ may involve various inputs in the form of linguistic data which are inherently vague, or human perception, judgement and evaluation for the information and data. This research focuses on how to deal with this kind of impreciseness in QFD optimization. In this paper, it is assumed as more realistic situation that the values of TAs are taken as discrete, which means each TA has a few alternatives, as well as the customer satisfaction level acquired by each alternative of TAs and related cost are determined based on subjective or imprecise information and/or data. To handle these imprecise information and/or data, an approach using some basic definitions of fuzzy sets and the signed distance method for ranking fuzzy numbers is proposed. An example of a washing machine under two-segment market is provided for illustrating the proposed approach, and in this example, the difference between the optimal solution from the fuzzy model and that from the crisp model is compared as well as the advantage of using the fuzzy model is drawn.

  • The purpose of this study was to know how helmet and armor was reinterpreted in historical play by considering general concept and type of old helmet and armor from the aspect of costume history and comparing the helmet and armor types of TV historical plays, Yeongaesomun and Taewangsasingi, whose historical backgrounds were based on the age of Goguryeo. The helmet and armor type shown in Yeongaesomun was reinterpreted as the one, which is close to historical investigation, by reappearing lamellar armor and jongjangpanju(helmet made of slim, long plate) shown in Goguryeo wall painting. The helmet and armor type shown in Taewangsasingi expresses fantastic helmet and armor by adding fantastic factor regardless of historical investigation. The study result reveals that there are several common characteristic factors between the helmet and armors of two historical plays. First, there was a classification in the display of character and story. The helmet and armor type shown in Yeongaesomun classified color and detail design depending on lamellar armor or character. In Taewangsasingi, the helmet and armor was manufactured depending on character's nature and the chain armors, which are lighter than existing helmet and armors, were usual. Second, they escaped from the historical investigation about traditional helmet and armor. In Yeongaesomun, myeonggwangae(a type of armor), which might be popular, was not expressed and Taewangsasingi is free from an imperative idea of historical investigation by manufacturing helmet and armor referring to that of ancient Rome age. The modern sense was reflected to increase dramatic effect. The helmet and armor of Yeongaesomun provides modern feeling by using stainless steel material and modern color arrangement and that of Taewangsasingi is designed in modern, splendid way as it aimed at game development from the planning step.

  • This study aims to seek knitting methods that can enhance the neck design of seamless knitwear and to find out how to improve the designs by comparing and analyzing the characteristics of the knitting methods used for v-neck pullovers. The investigator analyzed the characteristics of the knitting methods and assessed the wearing sensation by using six different pieces of clothing for the experiment. The results were analyzed based on a variance analysis (ANOVA). Among the items showing significant results, the Duncan-test was used for more intensive research. As a result, while using the basic pattern of knitting methods, Experiment Clothes A ended up binding on the back neckline, and not making the hem of back. Also, the neck was the widest. In the case of the special neck, Experimental Clothes B (1:1), which had the least number of the knitting course in relation to the knitting ratio, the bottom part of the back body had the most wrinkles. According to the result of wearing sensation, the front part, the side part, and the back part showed similar results (p<0.000) in all items. Specifically, the appearance of the Experiment Clothes A (normal) in both the front and rear aspects were evaluated as the best. In the case of the special neck, the Experimental Clothes F was ranked the highest, whereas the Experimental Clothes B (1:1) was ranked the lowest. Based on the results of the study, it seems possible to provide concrete and technical data for the planning of unique and productive designs. With regard to seamless knitwear neck designs, a comparative analysis of the knitting method of v-neck pullovers will be of practical use in the development and manufacturing of the product.
