  • Ninety three strains (4.2%) of Vibrio parahaemolyticus were isolated from 2,239 samples of commercial marine products during 2006-2008 in Seoul, Korea. We examined 16 antimicrobial susceptibilities of 93 V. parahaemolyticus isolates. Antibiotic resistance of V. parahaemolyticus was most frequently observed to ampicillin (93.5%), followed by cephalothin (90.3%), streptomycin (87.1%), ticarcillin (55.9%), and amikacin (40.9%). Antibiotic susceptibility was most frequently observed to nalidixic acid, chloramphenicol and ampicillin/sulbactam (100%), followed by trimethoprim/sulfamethoxazole (98.9%), gentamicin and tetracycline (82.8%), and ceftriaxone (63.4%). In addition, the isolates also displayed intermediate resistance to kanamycin (79.6%), ciprofloxacin (64.5%), amikacin (47.3%) and cefoxitin (43.0%). All isolates were resistant to more than two drugs. The most prominent multiple drug resistance was 3 drug resistance (37.6%), followed by 4 drug (24.7%), 5 drug (17.2%), and 6 drug resistance (11.8%). The most prominent multiple drug resistance pattern was the cephalothin-streptomycin-ampicillin resistance pattern (22.6%), followed by cephalothinticarcillin-streptomycin-ampicillin (18.3%) and cephalothin-ticarcillin-streptomycin-ampicillin-amikacin (9.7%). Multiple drug resistance patterns of V. parahaemolyticus from marine products require continuous monitoring.

  • The RSA public key encryption algorithm, a few, key generation, factoring, the Euler function, key setup, a joint expression law, the application process are serial indexes. The foundation of such algorithms are mathematical principles. The first concept from mathematics principle is applied from how to obtain a minority. It is to obtain a product of two very large prime numbers, but readily tracking station the original two prime number, the product are used in a very hard principles. If a very large prime numbers p and q to obtain, then the product is the two $n=p{\times}q$ easy station, a method for tracking the number of p and q from n synthesis and it is substantially impossible. The RSA encryption algorithm, the number of digits in order to implement the inverse calculation is difficult mathematical one-way function and uses the integer factorization problem of a large amount. Factoring the concept of the calculation of the mod is difficult to use in addition to the problem in the reverse direction. But the interests of the encryption algorithm implementation usually are focused on introducing the film the first time you use encryption algorithm but we have to know how to go through some process applied to the field work This study presents a field force applied encryption process scheme based on public key algorithms attribute diagnosis.

  • Many companies are trying to enter into overseas markets to overcome the limited size of domestic markets. However, there are many barriers to enter the overseas markets such as difficulty to find buyers and make contract with them, payment risks, unfriendly foreign policies, and etc. Companies have used to various strategies to get opportunities of overseas markets. One of them is UN public procurement. Despite many advantages, limited number of companies are participating in the procurement. Individual governments are providing policies to support local companies to participate in the UN public procurement. However it is not easy to encourage firms, especially SMEs to participate in the procurement. This study is designed to analyze firm and product determinants of participating in UN public procurement. Based on literature reviews and empirical findings, this study shows social responsibility and global orientation can play an important role regarding the participation. In addition, the positive relationship between UN public procurement participation and sustainability in a given firm could be empirically supported. Last, we suggest combining country- and industry-level data to investigate UN public procurement participation as an interesting topic for future research. This study represents various determinants to encourage UN public procurement participation. They may contribute to enhance firm performance such as sustainability.

  • Commonality strategy is a popular design practice in designing a product line as it enables the firm cost saving and simplification in design, manufacturing, and distribution processes. However the issue of commonality has been mostly analyzed from a profit maximizing firm's perspective and, to our knowledge, there is no literature that deals with the issue from a different perspective. in this paper, we consider the issue of commonality strategy from a social welfare maximization perspective, and argue that commonality strategy used in designing of public goods can bring certain benefits not just for a firm but also for consumers, i.e., for society as a whole. While we assume certain cost saving in production process due to economies of scale under commonality strategy, we conceptualize two different effects of commonality strategy, utility effect due to cost saving and weighted-averaging effect, and show how these two effects interplay to determine the design of common attribute and desirability of commonality strategy. We also discuss how the implementation of commonality strategy differs under different objectives of a product line designer : social welfare and firm's profit maximization.

  • The purpose of this research was to examine the extent of deontological (values) and teleological evaluation (considering consequences) used in arriving at an ethical judgment concerning intention to purchase a fashion counterfeit. In addition, the effect of psychographic (attitudes toward counterfeiting, risk taking, self-image, value consciousness, public self-consciousness, and materialism) and product attributes (perceived fashion content, physical appearance, and image) on intention to purchase a counterfeit product were investigated. Two alternatives and possible consequences as well as the scenario were given to the participants. The first alternative is persuading a friend not to buy a counterfeit and the second alternative is purchasing a counterfeit product with a friend. Participants (n = 245) were undergraduate volunteers enrolled in courses at a Midwestern university. Data were analyzed using confirmatory factory analysis and structural equation modeling. The proposed structural models fit the data adequately in both alternatives, and all paths were significant. Participants followed the decision making steps outlined by Hunt and Vitell (1986) in both alternatives. Personal characteristics exerted no influence on behavioral intentions concerning counterfeits. Two product-related characteristics (i.e., physical appearance of a counterfeit and projected image of a counterfeit) had direct effects on the behavioral intentions. The conclusions of this research are helpful in improving our understanding of variables that influence consumers' purchasing counterfeit luxury products.

  • Common Criteria(CC, ISO/IEC 15408) is an international standard for evaluation of Information Suity Systems(ISS). There need a suitable evidence of estimation of evaluation cost in an evaluation facility under the CC-based evaluation and assurance scheme. In this paper, we propose an evaluation effort model, which is based not only on assurance-level but also on product-type of ISS, by means of real experience of real evaluators, use-ratio concept and the Function Point of security function. The model is based not on a real evaluation environment of evaluation facility, but on CC, public PPs and product specific STs. Our result might be used as a basic model for estimation of evaluation cost and time of ISS in an CC-based evaluation and assurance scheme.

  • With the development of synthetic dyes, excellent dyeing properties and massive production became possible. On the other hand, natural dyeing technology has gradually disappeared. However, the international environmental and human safety requirements of the apparel and textile industry are increasing, and there is a growing interest in safer and more environmentally friendly products. Accordingly, the public's interest in natural dyeing is increasing. To meet these demands, it is first necessary to clarify the stages of production and distribution of natural dyes. It is necessary to evaluate whether the product is a natural dye product and study the suitability of the natural dye product through qualitative and quantitative assessment of the indicator components of the natural dye. Typical of three natural dyes did qualitative and quantitative analysis by HPLC-DAD and HPLC-MS. Products dyed using natural dye three products were analyzed, and the presence or absence of detection of each indicator components was confirmed to confirm whether the product was dyed using natural dyes.

  • A Product-Service Systems (PSS) is composed of service and product element to provide values for relevant stakeholders. A typical service interaction involves providers and receivers, and respective values are provided in a social interaction. In cases, more than one providers are interacting with a receiver. In others, service interaction is happening in a public manner where social issues amang peer receivers are important. When service channel is supported by physical touchpoints, receivers would interact with products, which may interact with providers. Thus, in PSS, a various kinds of interactions occur in diverse social contexts. A simple representation method for social contexts is introduced where service providers, receivers and products are represented as nodes and interaction between them are represented as directed edges. Social context of several PSS examples are described with this. In booth designing and operating PSS, social context representations could be used in analyzing and comparing key aspects of social interaction types to retrieve similar cases to exploit related interaction design strategies and operation know-hows.

  • The purpose of this study is to interpret the artistic nature of fashion from the point of view of George Dickie's Institutional theory of art, which defined art from a sociological context. Five notions to formulate the institutional definition of art were regarding the artist, work of art, public, artworld, and artworld system. These notions were applied to the fashion world, and they deduced the definitions of a fashion designer, a fashion product, a fashion consumer, and the fashion system, which indicated fashion's social status in the art system. Firstly, a fashion designer plays a collective role in the product with an understanding of the consumers, professional knowledge of the design, and knowledge of making images of fashion products. Secondly, a fashion product involves artifactuality in the form of clothes created by collaboration among producers and it is transformed into fashion by collective activity of distributors and consumers. Thirdly, a consumer is a set of people who play a leading role in the assessment and consumption of the fashion product, allow the fashion designer to read his or her taste and reflect it in the fashion product although they are not directly involved in its production. Fourthly, a fashion system is a social framework for the presentation of a fashion product by a fashion designer to a consumer, and a social institution which enables clothes to transform into fashion through design, production, display, distribution, and sales. As a result, fashion is defined as an artifact in the form of clothes created by a fashion designer and presented to a consumer by the fashion system.
