The current study investigated the fate of organic matter in piggery slurry under two different store systems(closed store system and open store system) in association with different temperature. Thirty days after storing in both systems at $20^{\circ}C$, it was observed that the content of organic matter remained in piggery slurry with closed store system was twice more than that with open store system implying more efficient degradation of organic matter with open store system. Temperature also influenced on the organic matter degradation in piggery slurry as shown decline in TS and VS contents as the temperature increased. With store at $35^{\circ}C$, 29% of initial organic matter was reduced while there was only 23% reduction of organic matter at $20^{\circ}C$. There was no difference in the type of organic fatty acids(VFAs) produced under the range of temperature(20, $35^{\circ}C$) simulating summer condition. Increases in organic fatty acids contents with hydrolysis and acid producing microbial was observed from 15 days after initiating store of the piggery slurry and the total organic acid amount produced 30 days after store was $2,829\;mg{\cdot}COD/L$ and $9,123\;mg{\cdot}COD/L$ at $20^{\circ}C$ and $35^{\circ}C$, respectively. These corresponded to 5.4% and 17.4% of the initial organic matter contents in piggery slurry, respectively.

This study proposes a research model that examines the impact of perceived technological innovativeness on curiosity and fun, which influence revisit and word-of-mouth intentions for an augmented reality store. Data was collected from 189 female consumers in their 20s and 30s living in the Seoul metropolitan area using a convenient sampling method. The results of the study were summarized as follows. First, perceived technological innovativeness was found to have positive effects on curiosity and fun. Second, curiosity had a positive relationship with fun. Third, curiosity had positive effects on revisit and word-of-mouth intention toward the augmented reality store, while fun had no effect on revisit and word-of-mouth intention. Fourth, curiosity mediated the relationship between perceived technological innovativeness and revisit intention, and between perceived technological innovativeness and word-of-mouth intention. The introduction of innovative technology in the offline store leads to a positive response through curiosity rather than fun; therefore, it is suggested that fashion companies develop and utilize augmented reality content that stimulates more curiosity.

In-store atmospherics involve quantified physical and social aspects; however, the social quality of a web-based retailing context has largely been under-examined. This study addressed some antecedents and consequences of social ambience in virtual shopping (or e-social ambience) within a web-based U.S. retailing fashion context. This study explored the role of social cues as a viable antecedent to e-social ambience and emotions as its consequence. A conceptual framework was built postulating the effect of social cue for web content, on e-social ambience, emotions, and e-shopping enjoyment. The experimental results (n=488) on a fictitious retail T-shirt website confirmed the positive correlation among the variables; in addition, the level of social cues included within the web content significantly increased the level of customer-perceived e-social ambience of the website and subsequent positive on-site emotions. On-site emotions positively influence purchase intentions. The results expand the current understanding of e-store management by providing novel insight relevant to fashion companies that wish to provide customers with a quality website shopping experience.

The research was conducted to provide basic information for store temperature which were low and room temperature and packing methods which were vacuum, packing and nitrogen of 3 year-old Platycodon grandiflorum. We investigated hardness and content of saponins, 1) platycodin D3, 2) polygalacin D and 3) deapioplatycodin D, in Platycodon grandiflorum and hardness of Platycodon grandiflorum, which were reduced by increasing storage period and decreased with increasing storing temperature, respectively. The packed storing method was better than others storing methods in low temperature. The high root hardness was significantly related with storing temperature and methods. The content of saponins in Platycodon grandiflorum, i.e., platycodin D3 and polygalacin D were reduced during storing period, however, the content of deapioplatycodin D was increased during storing period.

In various fields of information technology, it is growing up the needs about dynamic content management systems to store and manage SGML(Standard Generalized Markup language) documents in a database system. In this paper, we consider the issue of storing SGML documents that having complex hierarchical structure into a database system, and then propose a data model based on ODMG(Object Database Management Group) object model in order to store SGML documents without loss of information. Because the proposed data model reflects physical element structure and logical entity structure of SGML documents, it is able to store the SGML document in a database system at the system at the element- level granularity without any information loss. And also the proposed data model can be adapted among ODMG-compliant object database management systems. Finally, we will discuss on the implementation details of SGML repository system supports the functionality of automatic database schema creation for any DTD(Document Type Definition0, the functionality of storing the SGML document, the functionality of dynamic document assembly from stored database objects to SGML document, and the functionality of indexing and searching for database objects.

Recently, media platforms such as YouTube and Twitch provide services that can generate personal revenue by utilizing media content produced by individuals. In this regard, interest in the copyright of media content is increasing. In particular, in the case of an audio source, competition for securing audio source copyright is fierce because it is an essential element for almost all media content production. In this paper, we propose a method to store the audio source and its signature using a blockchain and distributed storage system to verify the copyright of music content. To identify the possibility of extracting the audio signature of the audio source and to include it as blockchain transaction data, we implement the audio source and its signature file upload system based on the proposed scheme. In addition, we show the effectiveness of the proposed method through experiments on uploading and retrieving audio files and identify future improvements.
