The purpose of this study is to seek the methods of constructing a cultural information system based on GIS. It is impossible for regional culture to be formed apart from its surrounding space, so a study of culture should be based on realizing the features of its space. It is important to note that the elements composing a culture complicatedly interact with each other in their function and continuously change. Also they are interrelated in space and plentiful in their amount. Nevertheless, those studies practised so far in relation to culture and constructing cultural database are too limited in establishing cultural area or community life area required to recognize the regional identity So it is now essential that we should study the methods of cultural expression surpassing objective historical and cultural site maps instead of simple maps depicting historical remains or sites. From this viewpoint, this study tries to find various cultural phenomena in relation to their space through seeking the methods of constructing the cultural database model using XML. In addition, this study tries to construct a base for increasing the utilization of information in making the cultural contents.

Content used in mashups is typically obtained from a third party source through a public interface or API (web services). Other methods of obtaining content for mashups include Web feeds (e.g. RSS or Atom), and screen scraping. A mashup or meshup Web application has two parts: A new service delivered through a Web page, using its own data and data from other sources. The blended data, made available across the Web through an API or other protocols such as HlTP, RSS, REST, etc. There are many types of mashups, such as consumer mashups, data mashups, and Business Mashups. The most common mashup is the consumer mashup, which are aimed at the general public. Examples include Google Maps, iGuide, and RadioClouds. 4D Wall-map display is data mashups combine similar types of media and information from multiple sources into a single representation. This technology focus data into a single presentation and allow for collaborative action among ITS-related information sources.

This study measured the effect of PPL(Product Placement: PPL) in OTT(Over The Top) to search a new advertising revenue model according to the change of viewers' video content consumption patterns. On the first, by two research steps, the experiment was carried out using an eye-tracker and then a survey as the second step was administered asking subjects about their attitude about advertising messages, attitude about brand, and intention to purchase the brands used in the experiments. Specifically, the PPL materials used in the experiments were classified with three parts. This study has the meaning as approaching to the PPL research with new methodology by quantitatively access through the eye tracking of the subjects beyond the conventional qualitative measure that depends only on the memory of them. This research aims to find the possibility of indirect advertising as a new revenue model in the OTT environment.

As the e-learning market expands, interest in customized education for learners based on artificial intelligence is increasing. Customized education for learners requires essential components such as a large amount of data and learning contents for learner analysis, and it requires time and cost efforts to collect such data. In this paper, to enable efficient learner-tailored learning even in small learning groups, unstructured learner data was analyzed using python modules, and a learning algorithm was presented based on this. Through the analysis of the unstructured learning data presented in this paper, it is possible to quantify and measure the unstructured data related to learning, and the accuracy of more than 80% was confirmed when analyzing keywords for providing customized education for learners.

The lifestyle of the new consumer class of people with diversified social structures and tastes is affecting society as a whole. As of now, emerging lots of complex cultural space with unique sensibility and individuality, this paper is about proposing the branding of a complex cultural space. I selected Sounds Hannam as a cultural complex and conducted in-depth interviews about brand experience and Ethnography. The study found that Sounds Hannam needs sense of hearing and smell because the sensory factors of the Sounds Hannam are concentrated in the visual field, and also, there is a need to create an appropriate communication channel through SNS. The Sounds Hannam had the characteristic factors of sensibility, relaxation and content based on a diversity different from the existing one. Throughout research, it was derived that planning space as a place to inspire people through spatial composition that triggers behavior and creative thinking is the goal of a complex cultural space and at the same time, an effective way to reflect the lifestyle of those in 20s.

B2B registries provide spaces to register and retrieve information which is necessary to support B2B transactions among business partners or potential business partners. Business process specifications are one of important contents in B2B registries, and there is high complexity of representation due to complex and dynamic characteristics of business processes. Also, currently there exist several competing specification frameworks such as ebXML BPSS, WSBPEL, BPMN, and so on. This paper proposes a metadata schema to register business process specifications which are represented by different specification frameworks. The proposed schema has extensibility to register business process specifications which are represented by various different specification frameworks. Also, it extends reuse level from whole business specification processes to their components. To show the usefulness of the proposed schema, this paper demonstrates metadata extraction from business process specifications which are represented by two representative XML-based business process specification languages, ebXML BPSS and WSBPEL.

The purpose of this study is to analyze ego state types of teacher librarians by using egogram of the Transactional Analysis. It is the ideal ego state types for teachers that NP (Nurturing Parent), A (Adult) and FC (Free Child) are much higher than CP (Critical Parent) and AC (Adapted Child). But the teacher librarians are under higher CP and AC rather than A and FC. It means that the teacher librarians consider their values and belief as right things. Also it seams that they have not a conciliatory attitude but a hardened attitude that emphasize rules and standards. These ego state may be obstacle to their instructors role under the constructivist learning environment highlighting self directed learning of students. So, in the training course for the teacher librarians, informational and educational service course and development programs of education contents and instructional materials should be reinforced in order to strengthen their teaching competence and partnerships.

In this paper, we propose gesture recognition based 3D Serious Games to prevent dementia. These games are designed to enhance the effect of preventing dementia by helping increase brain usage and physical activities of users by the entire body gesture recognition. The existing cameras used for gesture recognition technology are limited in terms of recognition ratio and operation range. For more stable recognition of the body gestures, we recognized users with a 3D depth camera, obtained joint data of users, and analyzed joint motions to recognize gestures of the body. Game contents were designed to practice memory, reasoning, calculation, and spatial recognition focusing on the atrophy of brain cells as a major cause of dementia. Game results of each user were saved and analyzed to measure how their recognition skills improved.

Industrial IoT has much interested in wireless mesh networks (WMNs) due to cost effectiveness and coverage. According to the advance in caching technology, WMNs have been researched to overcome the throughput degradation of multihop environment. However, there is few researches of cache power consumption models for WMNs. In particular, a wired line based cache power consumption model in content-centric networks is not still proper to WMNs. In this paper, we split the amount of cache power from the idle power consumption of CPU, and then the cache hit ratio proportional power consumption model (CHR-model) is proposed. The proposed CHR-model provides more accurate power consumption in WMNs, compared with the conventional cache power efficiency based consumption model (CPE-model). The proposed CHR-model can provide a reference model to improve energy-efficient cache operation for Industrial IoT.
