The word P2P implies significant changes in current business dynamics. The P2P service enables individuals to be connected to the Internet for the direct provision of information and even downloads from one another without the conventional method of passing through search engines. This can be utilized to extend the path of retrieving information from limited web sites to personal and enterprise databases. That is, it is now possible for individuals to manage their own information on a national or global scope, share various information with other members, form communities of users interested in sharing homogeneous information, and utilize remote conference and remote education using groupware.

As smartphone usage increases, the number of consumers who refer to review data of e-commercial products using web sites and SNS is also explosively multiplying. However, reading review data using traditional websites and SNS is time consuming. Also, it is impossible for consumers to read all the reviews. Therefore, a system that collects review data of products and conducts sentiment word analysis of the review is required to provide useful information. The majority of systems that provide such information inadequately reflect the properties of the product. In this study, we described a system that provides analysis and evaluation of e-commerce products through review sentiment words as reflected properties of the product. Furthermore, the system enables consumers to access processed information about reviews quickly and in visual format.

Communication log data consist of communication events such as sending and receiving e-mail or instance message and visiting web sites, etc. Many countries including USA and EU enforce the retention of these data on the communication service providers for the purpose of investigating or detecting criminals through the Internet. Because size of the retained data is very large, the efficient method for extracting valuable information from the data is needed for Law Enforcement Authorities to use the retained data. This paper defines the Interactive Communication Sequence Patterns(ICSPs) that is the important information when each communication event in communication log data consists of sender, receiver, and timestamp of this event. We also define a Mining(FDICSP) problem to discover such patterns and propose a method called Fast Discovering Interactive Communication Sequence Pattern(FDICSP) to solve this problem. FDICSP focuses on the characteristics of ICS to reduce the search space when it finds longer sequences by using shorter sequences. Thus, FDICSP can find Interactive Communication Sequence Patterns efficiently.

The purpose of this study is to link the Yi tribe's traditional patterns to bag design. Yi tribe is a minor ethic group in China, whose traditional pattern has a high artistic value in that its shapes are diverse and each one has peculiar elegance. Traditional patterns are also indicative of spiritual dept or symbolic stories, rather than being indicative of simple formative beauty. Thus, reorganizing these patterns and applying them artistically to design- in terms of resource utilization- would be significant. Out of all of the Yi tribe's traditional patterns, the cherry blossom_(马樱花), water wave_(水波), sky father and earth mother_(天父地母), pomegranate blossom, triangle, sheep' horn, wisteria vine_(藤条), square and diaper_(四角菱形) and the zigzag_(曲折) patterns were chosen for use during the development of a bag design. This study is based upon document study, including research papers and internet web sites, the point of which was to investigate the form of the traditional patterns, and the creative design process. The design procedure includes these sub-processes: selection, arrangement and color-scheme. In the selection process, the form of the pattern was edited using Adobe Photoshop. The pattern was freely arranged to reflect various emotions. In terms of the color-scheme of the patterns, the colors used by Henri Matisse(1869-1954) in his work were selected and adapted when dyeing the patterns. Subsequently, the final design resulting from these design development processes was applied to the actual production of the bag by using canvas fabric and leather, after which the bag image was proposed using computer simulation. In conclusion, six bag designs were created using traditional patterns from the Yi tribe. Through the processes explained above, this study confirmed that traditional patterns could be widely applied as design motifs and that more sophisticated, modern, and creative designs could be developed based on traditional patterns.

It's getting popularized to collect information connecting web sites with massive information through the internet and advanced search engines. Users can handle digital materials like E-book wherever the internet is available and they will demand digital information increasingly. This study analyzes literature investigation, statistics analyses of the attached library of Kyushu University, drawings and field investigation to suggest a new model of a library which handles traditional paper-formed materials and digital-formed materials at one place with growing importance of digital materials. It results that a library performs a important role like a learning space and functions as a sociocultural communication space. Also it shows that it is required to basically reinvestigate the role of 'space' in the library with a great importance of digital materials. In the hybrid library combined with subjects and reorganized at one place, One-stop services like library materials and manpower can be provided for users staying at the same area.

Background: Dental sedation reduces fear and phobia during dental treatment and helps patients get quality treatment by inducing adequate consciousness control. Propofol has recently grabbed the spotlight, but no meta-analysis for efficacy and safety of propofol in dentistry has yet been performed. Thus, the purpose of this study was to perform meta-analysis to verify the efficacy and safety of propofol for use in dental sedation. Methods: Articles published between 1980 and 2010 were searched in the web sites, journals and medical database including The Cochrane Library, MEDLINE and EMBASE. And a total of 22 studies were selected among the randomized controlled trials (RCTs) that compared the use of propofol with other sedatives (control group). The data was collected from these studies and meta-analysis for efficacy and safety was performed using Comprehensive Meta-Analysis 5.0 (CMA 5.0). Results: The patient recovered significantly faster and discharged significantly earlier in the propofol group (SMD = -1.442, P < 0.001). The satisfaction of patient and that of operator was higher in the propofol group (P < 0.05). The incidence of arrhythmia and apnea/ hypoventilation was significantly lower in the propofol group (OR = 0.071, P < 0.05), and there was no significant difference in the other side effects. On the level of sedation, although the sedation score was significantly lower in the propofol group (SMD = -0.430, P < 0.05). Conclusions: The present analysis showed that the use of propofol resulted in high satisfaction levels on the part of the patients and operators, a shorter recovery time, and faster hospital discharge. The incidence of complications, however, was lower in the propofol groups or not much different between the propofol and control groups. Thus, the adequate use of propofol in dentistry is believed to be helpful for the effective and safe sedation of the patients.

In this paper, we present the Mont-Saint-Michel virtual reality system designed to create the virtual heritage environment, which is enriched with personalized tour guide service. The tour guide system allows users to travel in the virtual heritage site and get more information about the sites or items of user's interests. It also allows users to make their own tour guidebook with the pictures they have taken during the virtual tour and more detail descriptions from the tour guide database. It then generates the web-based tour guidebook for users to utilize it for the actual site visit or share it with others over the Internet. The components of this system are designed with the consideration of reusability to be used for other interactive tour guide systems. This paper describes the motivation the development and a preliminary user study of Mont-Saint-Michel virtual reality personalized tour guide system.

The study aims to examine how exposure to phonography on the internet affects adolescents' behaviour toward sexual assault and the sex trade industry based on the social learning theory. A nationwide survey was conducted on adolescents between the ages of 14 to 19. Responses from a total of 2,829 adolescents were obtained and utilized in the analysis. The analytic findings showed that Korean adolescents are heavily exposed to phonography on the internet. Students use the internet to search for pornographic web sites, and they periodically look for updated materials. The study showed that between 1.8% to 16.5% of adolescents, who were exposed to or watched pornographic materials, committed sexual assault and were guilty of sexually harassing others. 3.5%(95) of those who were surveyed experienced sex trade. Internet chat rooms are considered to be a contributing factor. The results show that adolescents who were exposed to phonography are more prone to committing the acts of sexual assault and sexual harrassment, and tend to be more influenced toward sexual violence.

Purpose: The purpose of this study was to review sexual abuse prevention education program for Korean elementary school students. Methods: Whittemore and Knafl's integrative review methods were used and Gough's weight of evidence was employed as a quality appraisal tool. Articles published in Korean or English were identified through electronic search engines and scholarly web sites using three keywords: "elementary school student", "sexual abuse", and "prevention education". Peer-reviewed articles published between 2000 and 2018 were included in this review. Results: Twelve articles met the inclusion criteria and were appraised as being high-quality. Among the 12 selected studies, seven were descriptive, while five were intervention studies. Sexual abuse prevention education programs were effective in improving perceptions, knowledge, attitudes, and preventive behaviors among elementary school students. However, deficiencies were found in the variety of educational methods, utilization of experts, and standardization of the content of sexual abuse prevention education. Conclusion: We need to provide various educational methods that are appropriate for specific developmental stages, and the sexual abuse prevention content should draw upon the current sexual education program administered to this population. Furthermore, parents and trained teachers or school health teachers should be included to provide effective education programs for elementary students.

The purpose of this study is to suggest the development of interactive services and technologies in the media industry. Through the analysis of domestic two-way broadcasting contents service, this study analyzed platform and services type according to service type of terrestrial broadcasting, SO operator and Telco. Also, by identifying the characteristics of interactive programs(open, interactive, personalized, stereoscopic), this study propose important convergence possibilities of the future providers and development plans through supporting technologies and services for each characteristic. In the case of terrestrial broadcasters, ARS, web sites and mobile apps were mostly provided in both directions, and SO and satellite broadcasting operators were found to provide diversity in interactive service operation using data domain. In the case of IPTV companies, most of them provide interactive services with additional video or information service through adjustment button or app, and cable TV operators had more adjustment data broadcasting than exclusive use data broadcasts. Therefore, domestic interactive broadcasting service type needs convergence type of revenue model needs and needs to be converted into new competitive interactive broadcasting program service environment.
