A sanitary quality of a university foodservice establishment was assessed in terms of time and temperature, pH and Aw, and microbiological evaluation. Critical control points during various phases in product flow of fried fish cake soup were identified using hazard analysis concept. The results are summarized as follows : 1) Time and temperature data indicated that phases of holding ingredients at room temperature after cooking, and hot - holding of soup before assembly were critical. 2) pH and Aw values were in favorable for microbial growth. 3) Microbiological data indicated that microbial quality of ingredients was in poor condition. A holding practice of cooked ingredients at room temperature might provide the chance for microbial contamination and multiplication. Hot - holding time and temperature of soup should be strictly controlled to assure the food safety, since the microbial quality of serving food can be directly influenced by the hot - holding temperature of soup. 4) Microbiological test results for food containers, equipments, working surfaces, and supplies indicated that sanitary conditions of earthenware, gloves, wiping cloths and cutting board should be improved promptly. 5) Critical control points identified were : ingredients, pre - preparation, post - preparation, and holding before assembly and service. 6) Guidelines for the effective quality control program for this operation were suggested.

As transit networks are becoming more multimodal, the concept of connectivity of transit networks becomes important. This study aims to develop a quantitative model for measuring the connectivity of multimodal transit networks. To that end, we select, as evaluation measures of a transit line, its length, capacity, and speed. We then define the connecting power of a transit line as the product of those measures. The degree centrality of a node, which is a widely used centrality measure in social network analysis, is employed with appropriate modifications suited for transit networks. Using the degree centrality of a transit stop and the connecting powers of transit lines serving the transit stop, we develop an index quantifying the level of connectivity of the transit stop. From the connectivity indexes of transit stops, we derive the connectivity index of a transit line as well as an area of a multimodal transit network. In addition, we present a method to evaluate the connectivity of a transfer center using the connectivity indexes of transit stops and passenger acceptance rate functions. A case study shows that the connectivity evaluation model developed in this study takes well into consideration characteristics of multimodal transit networks, adequately measures the connectivity of transit stops, lines, and areas, and furthermore can be used in determining the level of service of transfer centers.

As automobile drivers' desires become ever diversified with the spreading phenomenon of 'characteristic automobile decorations', it is feared that the design quality may be deteriorated, while the safety be retarded in terms of performance and function. In Korea, the 'Dress-up tuning' becomes the source of the social criticism because of lack of relevant codes and professional tuning services, while automobile drivers are excessively having their automobiles overdressed ignoring the overall aesthetic aspect and functions. Under such a circumstance, this study was aimed at reviewing the practices and dress-up accessories by each automobile part of those foreign automobile makers and professional tuners who have introduced the concept of 'customizing' and developed dress-up accessories and various tuning parts only to satisfy their customers' tuning needs. It is anticipated that automobile styling would tend more to pursue a 'coordination' featuring ordinary consumers' individualistic senses, while customers' needs reflecting their life styles be more refined. Meanwhile, Korean automobile consumers have accommodated the product designs : presented within the producers' frameworks, but they are expected to pursue the design values varying according to changing structures of production, society and industry as well as the resultant design activities. In all, makers and designers are requested to be aware of such changing environment structures and thereby, explore other alternatives, or reflect seriously on the socio-cultural implications inherent in the products, namely on the production and consumption of people's favorites.

Although many PCR-based assays have been developed, the majority of rapid detection of Toxoplasma gondii in animal and their meat product has been dependent on immunogenic assays. Thus, there is still a need for more reliable PCR based detection method for T. gondii in retail meats. Recently, a 529-bp repeat element that exists in 200-300 copies per genome of T. gondii genome had been spotlighted for its usefulness as potential detection targers. In this study, the 529-bp repeat element was selected for real-time PCR to detect three types of T. gondii (type I, II and III). A primer pair targeting 82-bp of the 529-bp element detected all three types of T. gondii and showed high level of specificity against 14 different food-borne pathogens as well as 3 protozoan parasites such as Giardia lamblia, Cryptosporidium parvum and Entamoeba histolytica. Application of the new real-time PCR assay in meat samples showed improved detection sensitivity compared to the B1-gene targeted method suggesting potential new target for Toxoplasma gondii screening in retail meats.

The remark by Andy Clark that the cleverer our world is, the more difficult we perceive our world and ourselves, is very significant to us living in digital world. As the huge power of Technology are dominating the world, the people are drifting with their body fragmented in diverse kinds of chaos, being are faced with the situation that they should reorganize themselves about personal life and ways of thinking in a new technological environment. This paper approach some characteristics of contemporary society through 'Cyborg' which is the product of limitless human desire and technology. The characteristics in modern times, such as boundary disjoint, hybridity, transformation, fusion, communication with image, digital sensitivity, womanness correspond to those of the Cyborg. This paper also investigates the history of modern Cyborg through animation, one of the remarkable medium in digital age and analyze the cyber punk animation, and by Oshii Mamoru, which provoked the extension of the concept of Cyborg. This paper will give a moment to diagnose what this age is like and to present a reference line of our contemporaries exposed to the surplus images and technology.

A process-centric simulation modeling method has been proposed to define a shipbuilding simulation model. Existing modeling methods have limitations for expressing various production information for a shipyard. The advanced process-centric modeling method proposed in this paper offers an improvement, effectively representing production information and constraints for a shipyard. To achieve this, a method and diagram components to define a process-centric simulation model in detail have been suggested. The modeling method can assign priorities when multiple products and facilities are assigned to the process. And layer concept was applied to express simulation model with hierarchical structure. To verify the effectiveness of the modeling method, comparative analysis has been performed and the actual shipbuilding process has been modeled using the proposed method. When a single facility was used for various purposes, we found that the proposed method was more advantageous than existing methods. As a result, it was possible to express constraints and flows that were difficult to identify with existing process-centric simulation modeling methods, and the methods were improved for use in shipyard production planning verification simulations.

The purpose of this article is to delve into the problems of originality of the artwork by examining issues of reproduction within the contemporary art market. In contemporary arts, especially in terms of art production and consumption, we can't overlook society and its economic structure and its connection with of capitalism. As the purity of art creation has turned into an exchange value, art, especially an object as artwork, has fallen into the status of production in an economic marketing system. Walter Benjamin mainly referred to that point in his thesis Das Kunstwerk im Zeitalter seiner technischen Reproduzierbarkeit, which originated the sociology of plastic arts. This thesis, published in 1936, traced how the artistic functions of photograph and movie had been changed through the social development. His main concerns were movie and photograph but what I am concentrating from his point of view, is that even in the field of plastic arts, the manufacture of reproduction has been practiced as a primary method within the social and political contexts and development. Though I am referring to this in the main body of this article, reproduction in contemporary art strongly needs a new definition since it has been spread all over like a newest virus, not only by collector's personal taste or hut also by commercial circulations of these reproductions to the public. This relates to Benjamin's argument about the value of an exhibition at a museum(Ausstellungswert). Since the function of an artwork has been one of cultural industry, the manufacturing of reproduction raises unexpected problems, such as, the originality of the artwork, the value of an exhibition at a museum, its achievement as documentary and as a territory of art criticism. In this point of view, I want to inquire into the value and criteria of an exhibition in contemporary art through the review of the definitions and the intrinsic attributes of reproduction. Somehow in a broad sense, the reproduction is a product coming out of representation or copy (replica) of an original art work or an model. Therefore, the problems it presents differ from the Simulacre, which is an image without an original one. In terms of the Meanings of reproduction, we can distinguish it as reproductions, copies, and productions. These types of reproductions are not the original artworks reflected by the creative intention of the artists. For example, a publishing company reproduced some of lithographs of Salvador Dali in the 1960s. They are commercial copies in the form of representation or reproduction with no artistic and creative intention of the artist. However, In despite of this theoretical basis, reproductions of the famous artists are still displayed without any verification for of the public's quest for the artworks. Moreover, many commercial companies that are planning to exhibit art works of the world-famous artists only for their profits keep trying to speak ill of and judging by the law the honest art critics' articles which discuss the true values of exhibition. If freedom of expression is one of the ideals of democracy, even the judgment of the originality of the artworks should be freely expressed.

A chemical ranking and scoring (CRS-Korea) system was developed and proposed to use as the first step to prioritize the toxic chemicals for the purpose of monitoring and detailed risk assessment that might follow as necessary. The CRS-Korea system takes a basic concept of risk assessment (both human health risk and ecological risk) in that risk score is determined by the product of toxicity score and exposure score. Included in the toxicity category are acute toxicity, chronic/sub -chronic toxicity, carcinogenicity, and other toxicity. The exposure category consists of quantity released to the environment, bioconcentration, and persistence. A consistent scheme and a comprehensive chemical data base are offered in the CRS-Korea system to calculate a score for the each component in the two categories by using specific physicochemical, fate, and toxic properties and the quantity of the chemical used. The toxicity score is obtained by adding up all the individual scores for the components in the toxicity category. The exposure score is determined by multiplication of the score of the quantity released with the sum of persistent score and bioconcentration score. Equal weight is given to the toxicity score and the exposure score. As the CRS-Korea system was applied to identify 50 national priority chemicals, it was found that significant data gap exists on toxicity and fate properties and that the uncertainty associated with estimating the quantify released to the environment is notably high. The proposed CRS system is only a screening tool in the first step toward the priority setting and should be used with expert judgement and other considerations necessary.

Common law makes a distinction between partial breach and material breach. Attempted definitions of material breach are notoriously unsatisfactory, and the concept of partial breach does not necessarily bear an inverse relationship to substantial performance. This study will review the basic structure of common law contract remedies together with how these remedies are reflected in UCC Article 2 for sale of goods contracts. The matter is complicated because availability of remedy depends on the seriousness of the breach, and the right to cure, and (for sale of goods) these in turn depend on whether the contract is an installment contract or a single performance contract. Common law jurisdictions relegate specific performance of contracts to a last place in the hierarchy of contract remedies. Common law lawyers should recognize that this is the result of historical accident and not the product of some kind of superior intellectual effort. Not only is the attitude of civil law systems toward specific performance quite different, but for international sales contracts in developing nations, a remedy system based on the notion that substitute contracts are readily available(and therefore damage remedies are appropriate) is unrealistic. English common law courts were largely restricted to remedies in the form of monetary damages. For that reason the primary contract remedy at common law has never been specific performance. Rather, common law courts have struggled to develop an appropriate measure of monetary damages for breach of contract. Today, specific performance is viewed as an equitable remedy rather than common law. In the United States the dual court system has been abolished by a merger of law and equity courts into a single court structure. However some historical distinction linger on. The most important is that jury trials are generally not available in actions that seek equitable relief. If a plaintiff seeks in personam relief, such as specific performance of a contract, the action will be viewed as equitable and there will be no entitlement to a jury. Further, equitable relief will be granted only in those situations where the plaintiff pleads and proves that the remedy at law is inadequate. The purpose of this study aims to analyze the remedy system of breach of contract of U.K. and U.S. in the international commercial transactions with criterion of commercial rationality.

Due to the growing popularity of mobile information technology, more people, especially in the general public, have access to computerized geospatial information systems for wayfinding tasks or urban navigation. One of the problems with the current services is that, whether the users are exploring or navigating, whether they are travelers who are totally new to a region or long-term residents who have a fair amount of regional knowledge, the same method is applied and the direction are given in the same way. However, spatial knowledge for a given urban region expands in proportion to residency. Urban navigation is highly dependent on cognitive mental images, which is developed through spatial experience and social communication. Thus, the wayfinding service for a regional community can be highly supported, using well-known regional places. This research is to develop the framework for urban navigation within a regional community. The concept of communal ontology is proposed to aid in urban regional navigation. The experimental work was implemented with case study to collect regional landmarks, develop the ontological model and represent it with formal structure. The final product of this study will provide the geographical information of a region to the other agent and be the fundamental information structure for cognitive urban regional navigation.
