In the current era of digital technology, and with the help of existing software, digital photo manipulation is becoming easier and faster. One example of this is the development of powerful image processing software that makes it easy for a digital image to be manipulated and edited. It is therefore very important to protect and maintain public trust in digital images. Several methods have been developed to detect image manipulation. In this paper, we compare two methods for detecting image duplication due to copy-move actions, namely the polar coordinate system and the histogram of oriented gradients methods. The former is a method based on the transfer of a Cartesian image to a polar form, making it easy to tell whether there are objects that have undergone a copy/move in an image, while the latter is a method for retrieving information related to the distribution, which uses a target in the local area as a tool to represent the shape of the target. We compare the accuracy, speed and memory usage of these two methods.

This paper studies the R&D network of the Zhongguancun Cluster, the most representative innovative cluster of the high-tech industry in China at present. For this study, Zhongguancun Cluster was the first high-tech cluster to have been created in China, the current Zhongguancun Cluster has played a leading role in the development of the high-tech industry in China. In addition, the Zhongguancun Cluster has at helped elevate China as a key region in terms of research development in relation to the high-tech industry. In particular, companies evaluate the research development network culture of Zhongguancun cluster positively and this increases their tendency to approach the research development network with an open mind. The main contents in research development network are as follows; (1) joint or consigned research development and technology transfer in the case of research development network between companies, (2) joint or consigned research development, human resource support and employment, technical advice and consultant and technology transfer in the case of industrial-educational relationships (3) joint or consigned research development, technical advice and consultant and technology transfer in the case of industrial-research relationships, (4) financial support and participation in joint research development project held by government in the case of industrial and governmental relationships (5) financing for research development, utilization of research human resources, purchase of research development and use of research development equipment for mediators. The main difficulties in creating a research development network are 'lack of mutual trust', 'financial problems of companies' and 'lack of information'. Especially, the main key obstacles for the most important research development network between industry and government in the case of the Zhongguancun Cluster are 'complicated and strict procedures. Therefore, more accurate and detailed understanding of the conditions and the following institutional measures from government are required for research development among companies.

This study reviews the literature related to the omni-channel and derived structural relationship between experiential perception of omni-channel brand and consumer-brand relational quality. A total of 250 questionnaires were distributed to university students, workers, and consumers in Busan, Korea, who had experience using SSG.com. 210 questionnaires were used for final validation of research model. The hypotheses set in this study was validated through SPSS18.0 and LISREL8.3 based on the research model. The results showed that all hypotheses were accepted, except for 2 hypotheses(Hypothesis 2-3, Hypothesis 2-4). Findings of this study suggest the following:First, the consumer's experience with the omni-channel brand was found to be an important factor influencing consumers' cognitive and emotional responses formed by the transfer effect of experiential factors through senses. Second, the relationship between consumers and the omni-channel brand was found to be an important factor in building attachment and psychological bond through experience and trust for the omni-channel brand. Thus, the results of this study provide the basis for overall understanding of the strategic experiential module (SEMs) for the omni-channel, which recently emerged as a new trend of distribution channel, as well as for managing the spatial environment. Finally, we present the theoretical and practical implications related to consumers' experience and relational perception.

The purpose of this study is to investigate 1) the types of knowledge students ask for in their reading comprehension of science textbooks using an online annotation system, 2) the accuracy of the knowledge provided by the students to their peers, 3) the frequency of knowledge sharing behaviors, 4) the evaluation of the effect of collaborative reading, and 5) the trust among peers as knowledge sharers. Questions made by 241 students in the second grade of middle school using an online annotation system in two chapters of the science textbook were analyzed using Bloom's revised taxonomy and their answers were grouped according to five accuracy categories. Also, questionnaires for the evaluation of the effectiveness of collaborative reading comprehension and of trust among the students were used. The students asked their peers 'understanding questions' which comprised almost 80% of the total questions they made and were similar with individual metacognitive strategies for reading comprehension. Of the total threads, 71% has scientifically correct threads shared by the students. The frequency of the knowledge sharing behaviors was high but this was affected by the rewards (point system). Students evaluated that collaborative reading comprehension conducted through an online annotation system were helpful in their learning. In addition, the ratio of students trusting their peers who did the knowledge sharing is over 80%. This study shows that when students use an online annotation system, they can fill one another's cognitive gaps in the reading process by sharing knowledge. Also, collaborative reading using an online annotation system has proved that cognitive individualization is possible through sharing knowledge interactively and dynamically, unlike reading hard copies of textbooks which are a one way information transfer.

The objective of this study was to investigate and analyze the problems on 'System for Author's Property Right Limitation' in the North Korean Copyright Law. The NK Copyright Law had applied the international standards superficially, it may not be considered to get out of the grand frame of NK system. Especially, it is different that there is lack or short of contents on transfer, disposition, succession, trust, and so on for Author's Property Right. For example, free usages of Literary Works upon the NK law of Author's Property Right were described as 9 cases including copy and translation for personal purpose; copy in the library, etc. However, there are many insufficient items in view of international standards among the cases, showing omissions of critical terminology such as publications of literary works, purpose of usage, scope of usage, etc. Therefore, the NK law of Author's Property Right is interpreted not to be satisfied with the requirements for the law of Author's Property Right but to be legalized in terms of external announcement, and it seems not to be considered as the Author's Property Right Law with general standards enough to demonstrate the creativity freely.

Capsular contracture is the most common complication following implant based breast surgery and is one of the most common reasons for reoperation. Therefore, it is important to try and understand why this happens, and what can be done to reduce its incidence. A literature search using the MEDLINE database was conducted including search terms 'capsular contracture breast augmentation', 'capsular contracture pathogenesis', 'capsular contracture incidence', and 'capsular contracture management', which yielded 82 results which met inclusion criteria. Capsular contracture is caused by an excessive fibrotic reaction to a foreign body (the implant) and has an overall incidence of 10.6%. Risk factors that were identified included the use of smooth (vs. textured) implants, a subglandular (vs. submuscular) placement, use of a silicone (vs. saline) filled implant and previous radiotherapy to the breast. The standard management of capsular contracture is surgical via a capsulectomy or capsulotomy. Medical treatment using the off-label leukotriene receptor antagonist Zafirlukast has been reported to reduce severity and help prevent capsular contracture from forming, as has the use of acellular dermal matrices, botox and neopocket formation. However, nearly all therapeutic approaches are associated with a significant rate of recurrence. Capsular contracture is a multifactorial fibrotic process the precise cause of which is still unknown. The incidence of contracture developing is lower with the use of textured implants, submuscular placement and the use of polyurethane coated implants. Symptomatic capsular contracture is usually managed surgically, however recent research has focussed on preventing capsular contracture from occurring, or treating it with autologous fat transfer.

The industrial community in a metropolis has played an essential role to keep business in a large city. This paper aims to analyze the realities of trade network among enterprises at Buksungro Tools Commercial Cooperative in Daegu. The urban style industrial community is found at Buksungro in Daegu. There are more than one hundred small-sized enterprises. Major trades among enterprises are occurred within and/or by the area. The long-term trade networks within the Buksungro Tools Commercial Cooperative have played the key role to maintain the industrial community. The trade relationship has depended on business networks based on social capital rather than commercial mechanism. The trade networks have been established through credit transactions as well as handling troublesome orders. The trade networks help to transfer technology and to learn the tacit knowledge among firms. The long-term trade networks are more influenced by the social accessibility than spatial accessibility.

The greatest mission of archival community lies in collecting records to document past and present Korean society and in safeguarding them to pass over to the next generation. For the last decade, Korean archival community has actively pursued this mission and accomplished it to the certain extent. A series of events occurred during the last year urged the community to regretfully accept that the so-called accomplishment was by no means satisfactory. The present study aims to review what has been achieved against what should be if the community is to be truthful to the fundamental mission. It begins with addressing attributes of electronic records. To be specific, attributes of electronic records as 'records' are compared against those as 'digital objects.' Current state of long-term preservation of electronic records is reviewed. Suggestions follow in terms of four directions: establishing a policy framework based on principles of electronic records management, building integrated electronic records management system, researching and developing functionalities for long-term preservation, and finally, knowledge transfer and coordination.
