Human Astrovirus (HuAstV) is an important gastrointestinal pathogen that is frequently reported worldwide. Monitoring of contaminated groundwater has been suggested since HuAstV is transmitted through the fecal-oral route. This study developed a test method based on conventional reverse transcription (RT)-nested polymerase chain reaction (PCR) that involves SL^® non-specific reaction inhibitor for unknown non-specific amplification taking place in the groundwater environment. An optimal method for detecting HuAstV in groundwater sample through analysis and comparison against conventionally reported method was also suggested. The developed method enabled the production of nested PCR amplicon of 630 nt, which is a sufficient length for similarity analysis based on sequencing and genotyping. Amplicons suspected to be HuAstV were amplified in two out of the twenty groundwater samples collected in Korea, presenting 99.77% and 99.73% similarity against HuAstV 1 strain lhar/2011/kor (JN887820.1) in sequencing, respectively. These amplicons were identified as HuAstV 1.

Ontologies are knowledge containers in which information about a specified domain can be shared and reused. An event happens within a specific time and place and in which some actors engage and show specific action features. The fact is that several ontology models are based on events called Event-Based Models, where the event is an individual entity or concept connected with other entities to describe the underlying ontology because the event can be composed of spatiotemporal extents. However, current event-based ontologies are inadequate to bridge the gap between spatiotemporal extents and participants to describe a specific domain event. This paper reviews, describes and compares the existing event-based ontologies. The paper compares various ways of representing the events and how they have been modelled, constructed, and integrated with the ontologies. The primary criterion for comparison is based on the events' ability to represent spatial and temporal extent and the participants in the event.

Social reactions to body exposure in American leisure wear (bathing suits, shorts, and halters) in the 1930s were analyzed to provide an understanding of the process of adopting more abbreviated and less-occasion specific styles of garments in women's fashion. The research questions were as follow: How did women expose their bodies in leisure wear during the 1930s? How did the social reaction to women's body exposure in leisure wear change throughout the 1930s? How did the body exposure in women's leisure wear play a significant role in the history of women's fashion? Primary sources were collected from issues of The New York Times published in the 1930s. Topics including dress, fashion, ethics, social ethics, and sexual ethics, were reviewed in The New York Times indices. The findings were analyzed and interpreted with reference to secondary sources that included books and research papers. The results showed that the body exposure of the styles as well as the place where these styles were worn was a public issue. Women were criticized and regulated for body exposure as well as for wearing bathing suits, shorts, and halters on the streets. However, the social regulations that restricted bathing suit styles almost disappeared by the end of the decade. This represented the change of social expectations toward body exposure in the 1930s. In addition, reports of laws that forbade the wearing of bathing suits, halters, and shorts outside of beaches, pools, and parks indicated women's increased attempts to expose their bodies in public places. However, reactions to women's body exposure in leisure wear changed to accept more flexibility in the social customs throughout the decade. These phenomena were a partial step toward the popularization of less occasion-specific styles - sportswear - that took place in the 20th century.

This thesis explores the place and role of a performer's action from a perspective of a director and playwright David Mamet's concept for performer training. This thesis takes inspiration from the idea of Mamet's simple and practical investigation specifically in text-based approach with a performer's bodily function on stage. For Mamet, the writings and practices of many different body-centered training are not rooted in the principle and nature of acting/performance. Reconsidering complicated approaches particularly psychological-oriented theory, practice, and assumption draw on several practitioners takes us beyond the field of visible and/or outer appearance of a performer which in turn leads the performer's body to be as abstract therefore not to being in the moment on stage. Arming the points, we argue that whatever disciplines and/or methods necessarily need to meet the principles and demands of acting/performance/theatre to connect to the materials, an action/objective given by a specific playwright which the performer must inhabit through his/her body. Out of the context, any 'method' serves no purpose. That is, the mechanics of an action is an extension of addressing what a performer's specific needs which shifts his/her body to respond appropriately to the theatrical demands. Taking this argument further, we claim that the purpose of performer training should not be understood as learning and improving techniques or skills for his/her self-perfection. The research finding shows that this resembles to the phenomenon that the visible very often precedes the invisible where the performer's body lose a clarity with no more chance to happen and/or change the event(s). Rather, it is a process of learning what/how to learn which in turn brings us back to the central question of why we do training for what purpose in this contemporary era. Exploring and answering these questions is not only a way to employ the key materials applicable to the theatrical demands but also to achieve the identify as a professional performer/doer on stage.

Proteins interact with each other within a cell, and those interactions give rise to the biological function and dynamical behavior of cellular systems. Generally, the protein interactions are temporal, spatial, or condition dependent in a specific cell, where only a small part of interactions usually take place under certain conditions. Recently, although a large amount of protein interaction data have been collected by high-throughput technologies, the interactions are recorded or summarized under various or different conditions and therefore cannot be directly used to identify signaling pathways or active networks, which are believed to work in specific cells under specific conditions. However, protein interactions activated under specific conditions may give hints to the biological process underlying corresponding phenotypes. In particular, responsive functional modules consist of protein interactions activated under specific conditions can provide insight into the mechanism underlying biological systems, e.g. protein interaction subnetworks found for certain diseases rather than normal conditions may help to discover potential biomarkers. From computational viewpoint, identifying responsive functional modules can be formulated as an optimization problem. Therefore, efficient computational methods for extracting responsive functional modules are strongly demanded due to the NP-hard nature of such a combinatorial problem. In this review, we first report recent advances in development of computational methods for extracting responsive functional modules or active pathways from protein interaction network and microarray data. Then from computational aspect, we discuss remaining obstacles and perspectives for this attractive and challenging topic in the area of systems biology.

Even though place-marketingstrategies geared towards upgrading regional competitiveness have been brought to the forefront, due attention has not given to how to set up practical and viable strategies. Based on Geoff Coyle's ACTIFELD method, this study aims at formulating a series of implementation strategies of Jeungpyeong Place-Marketing. As the ACTIFELD technique contains intrinsic devices which would facilitate structural and systematic approach, it can easily encompass both qualitative and quantitative factors in reinterpreting complicated social phenomena and providing feasible alternatives. Furthermore, the study carries out additional public opinion surveys and expert brainstorming methods, as specific means to overcome relative weak points within the proposed ACTIFELD approach. The followings are major research findings. Firstly, in terms of maximizing existing strategies, Jeungpyeong should develop commercial items focused on Korean Ginseng and its byproducts. Secondly, among various festivals, Jeungpyeong should devise concrete processes to concurrently concentrate its support on Pork (Samgyupsal) and Korean Ginseng Festivals. Thirdly, as the majority of Jeungpyeong people prefers both do-it-your-self and traditional types, Jeungpyeong should prepare appropriate governance systems to deal with these issues. Fourthly, in order to contribute regional vitality, Jeungpyeong should strengthen public relation activities including guest-staying facilities. Lastly, Jeungpyeong should constantly improve the aggregate value of County Identity (CI)-based brands and it should also pursue production and public relation strategies actively applying the elderly.

The average increase in life expectancy obtained as a gift of modern science cannot hold itself responsible for extended life's happiness. It admits of no argument that the necessity of social preparation for minimizing bad health and longevity of unhappiness to aged people who are in the state of these continuous growth. Recently, because of an aging trend, targeting on elderly housing expected continuous increased demand in housing market, this study is to comprehend it's characteristic and offer implications. For the characteristic of elderly housing, firstly it needs scientific analysis of related theory and analysis of statistical data. Also this study aims to look through and suggest an alternative included the special matters of Korean society with advanced foreign country's analysis of an alternative. And judging from economic characteristics of elderly housing to be presented as an important factor, choices of housing according to economic level are anticipated to show different forms. In future, to supply elderly housing, therefore, the introduction of the concept of housing providing various opportunity of choice is necessary. If studies proceed through expanded alternative, it is judged to be able to draw more varied results in elderly housing. Also, if going along with political dimension study, it is expected to offer more specific and effective solutions of the problem of elderly housing.

The study examined the characteristics of internet shopping mall sites including on-line market places and integrated internet stores from a perspective of consumer protection. Specifically, the study investigated 1) whether sufficient information is provided on the internet shopping mall sites, 2) whether shopping mall sites abide by internet advertising principles, and 3) specific examples of consumer misleading potentialities from internet shopping sites. Further, on-line market places and integrated internet stores were compared based on their informativeness and potential consumer misleading factors. Total 50 shopping mall sites were analyzed for examining the types of information provided and consumer misleading factors. To verify study questions, descriptive statistics were used. For comparison between on-line market places and integrated internet stores, Chi-square test and independent-sample t-test were employed. The results of this study were as the following: First, not a few of the internet shopping mall sites did not provided important information such as safety and warrantees. Second, important disclosures were not noticeable on the web pages and distracting factors were frequently used. Third, integrated internet stores were desirable compared to on-line marketplaces based on informativeness and consumer misleading potentialities. As the result of this study, internet shopping malls need to advised to provide sufficient information and reduce potential misleading factors.
