This paper evaluates the governance of the Andong International Mask Dance Festival. The evaluation focuses on mutual cross-assessment of agents engaging in governance relating to four elements: social justification, reliability, professionalism and transparency. Governance based on co-operative partnership was the essential factor leading to the mask festival's success. Governance of the Andong International Mask Dance Festival in 2011 was privately initiated governance having horizontal and open partnership among festival specialists, civil society organizations, regional business organizations, volunteers and local government, with the Andong Festival Tourism Foundation as the central figure. Three of governance elements were successfully carried through; the exception was transparency. The agents who gave more positive evaluations were those who played leading roles in planning and conducting events, as well as in assessing those events. The reasons for positively assessing the elements are the significance of the festival and the guarantee of agents' participation in social justification; the ability of agents, as well as cognitional and institutional trust in reliability; expert knowledge, capacity to suggest alternatives and duality of business in professionalism; and effective communication, the guarantee of opening of information and information sharing in transparency. To improve the effectiveness of governance, the system for allowing passive agents to contribute usefully should be strengthened. Mutual communication and sharing of information among agents, as well as between agents and residents, also should be more strongly reinforced.

Query by visual example is the principal query paradigm for expressing queries in a content-based image retrieval environment. Query by image and query by sketch have long been purported as being viable methods of query formulation yet there is little empirical evidence to support their efficacy in facilitating query formulation. The ability of the searcher to express their information problem to an information retrieval system is fundamental to the retrieval process. The aim of this research was to investigate the query by image and query by sketch methods in supporting a range of information problems through a usability experiment in order to contribute to the gap in knowledge regarding the relationship between searchers' information problems and the query methods required to support efficient and effective visual query formulation. The results of the experiment suggest that query by image is a viable approach to visual query formulation. In contrast, the results strongly suggest that there is a significant mismatch between the searchers information problems and the expressive power of the query by sketch paradigm in supporting visual query formulation. The results of a usability experiment focusing on efficiency (time), effectiveness (errors) and user satisfaction show that there was a significant difference, p<0.001, between the two query methods on all three measures: time (Z=-3.597, p<0.001), errors (Z=-3.317, p<0.001), and satisfaction (Z=-10.223, p<0.001). The results also show that there was a significant difference in participants perceived usefulness of the query tools Z=-4.672, p<0.001.

Values can be regarded as an important factor which acts as an indicator showing each person's individual path of life. many researchers have suggested that values function as standards that guide thought and action. Values lead us to take particular positions on social issues and they predispose us to favor one perspective over another. Adolescence is an important period for the establishment of one's values. The values established during such a period become an important factor determining one's right personality and contents of life. In particular, it is important to take a study about the values possessed by gifted and talented children in Korea. There have been several researches regarding the cognitive and affective characteristics of gifted and talented learners in Korea. However, there has not been any research regarding their values in life. This study investigates the characteristics of values shown by 468 high-school students from two special schools for gifted students by using Schwartz's Value Survey Scale which is consisted of 57 value categories and 10 value types. According to the results of this study, the students from the special high-school for gifted children tend to promote such value types as 'autonomy' and 'stimulation' the most. Conversely, the same students tend to deny or ignore such value types as 'power' and 'tradition'. This study provides basic data regarding the values of gifted and talented students as the first research of its kind targeting gifted students in Korea. It has an important meaning for the research related to the characteristics shown by gifted students in Korea.

The purpose of this study was to empirically analyze relations between color changes in the product specification and demand changes with price elasticity in the Chinese mobile phone market. In previous studies on price elasticity, the usual analysis units were product categories or SBU within a given product category. Unlike them, the this study set an analysis unit of price elasticity to focus on colors, which are investigated in the research fields of experiential marketing, aesthetic marketing, and cognitive psychology. Actual sales data according to the mobile phone price changes by the color were based on the sales volume of a sales agency at China's largest B2C site. The findings were as follows: first, price elasticity according to the six colors was higher than the absolute value of 1, which means that demands made flexible reactions to price changes. Secondly, there were differences in price elasticity according to the colors. Aroma white color made the smallest increase in sales volume at the same price discount, whereas diamond color made the biggest increase in sales in the same price discount scope. These findings indicate that more profit can be generated in mobile phone sales in China by setting different price discount or increase rates according to colors or producing different amounts of mobile phones according to colors. Distributors or sales agents can have a chance for higher profit by ordering and selling mobile phones in certain colors than others from mobile phone manufacturers. The academic findings indicates that there are differences in preference and price elasticity according to colors under the mobile phone category in the Chinese market, which means that the present study made an academic contribution by proposing a microscopic analysis unit for product price elasticity and expanding its concept.

This study examined the consumer response of the current O2O service between service types. Previous studies mainly focused on the quality factor of O2O service or Technology Acceptance Model or extended TAM, This study is different from the fact that there are differences in factors that consumers consider important and consumer reactions by service type. It is also significant that we compared between representative food delivery services and car sharing services that are actively used among O2O services. As O2O service is closely related to consumer's life, this study chose three factors that the issue of personal information security and trust of intermediary platform companies, and finally subjective norm based on individuals and groups who are aware of new O2O service. To test hypotheses, data were collected and analyzed for 301 samples, focusing on delivery and car sharing service, As a result, the delivery service among the O2O services was more positive to attitude toward service in the consumer group with lower personal information security, trust in platform, and subjective norm than car sharing service. Based on these results, implications and future research directions were presented.

In spite of dramatic change of environmental condition since Cambrian big-bang (explosion occurred ca.540 mya, the phylum Arthropoda retains a great diversity, and it is estimated approximately that 1-10 million arthropod species are extant on the earth. Except for an extinct arthopod subphylum Trilobita, extant arthropods could be divided into five subphyla: Hexapoda, Crustacea, Myriapoda, Chelicerata, and Pycnosonida. During the last century, systematists have disputed about interrealtionships among Arthropoda and its relatives (Onychophora, Tardigrada, and Pentastomida), arthropod phylogenetic position within protostome animals, monophyly or polyphyly of the phylum Arthropods, and interrelationships among five arthropod subgroups (subphyla) etc. Recently, new animal phylogeny was reported that protostomes could be clustered into two groups, Lophotrochozoa and Ecdysozoa, and molting animals such as Nematoda and Arthropoda were included within the Ecdysozoa. On the basis of the new animal phylogeny, first of all, I would mention phylogenetic positions and relationships of Arthropods and its relatives to introduce controversies of arthropod phylogeny in phylum level of animals. After that, I focused mainly on the controveries related to arthropod monophyly and phylogenetic relationships among four major arthropod groups except Pycnogonida. In this work, Pycnogonida which is a relatively small group and one of the five arthropod subphyla was not handled significantly although there are some controversies if it is a sister taxon of chelicerates or the most primitive arthropod group (namely, a sister of four remains arthropod groups).

In addition to emphasizing practicality, as in some academic disciplines, LIS is also interested in the research activities and journal publishing of librarians. Despite the high interest, there are few Korean studies on librarian authors' publishing. This study focuses on analyzing the status of librarians' publishing and finding ways to activate their journal publishing. This study analyzed the papers of the librarian authors published from 2014 to 2018 in Journal of the Korean Biblia Society for Library and Information Science and identified the characteristics of librarians who are publishing. As a result, librarians accounted for 15.56% of all authors. However, it is encouraging that the number of librarians' authorship stabilized, and that many librarians are the main authors. Librarians who were energetically publishing were public or school librarians, and academic librarians were slightly behind. There were graduate student librarians who collaborated with the advisor. In order to increase the librarian's publishing, it seemed to be necessary to improve not only the librarian's efforts but also the recognition and assistance of his/her library. Both the librarian and his/her library should be aware of the importance of publishing the journals, and should establish concrete plans such as resilience, compensation, and support. In this way, the librarian's valuable practical experience will be published in research papers and widely shared among researchers and practitioners.

Currently Welfare is emphasized and the trend of SOC investment shows downwards slopping. The pattern of SOC investment also changes focusing on railroad as environmental issues are critical. This study analyzes and compares the effects of sectoral SOC investments based on Input-Output Tables published by BOK (Bank of Korea). The production inducement, value-added inducement, and employment inducement effects of each sector SOC, which consist of road, railroad, port, and airport, are investigated. First, in view production inducement, sectoral SOC investments have stronger economic effects than manufacture sector. The investment of port and road show the highest value-added inducement in construction process. The investment of road records the highest employment inducement in construction and operation process. The empirical ananlysis of regional economic effects, using Regional Input-Output Tables, supports these explanation showing almost same results. As synthesizing these results, the SOC stocks have to be invested consistently for long periods. Especially the road investment is inevitable for employment. Which sector of SOC is invested depends on circumstances. If government emphasizes production inducement, railroad is invested. If focuses on value-added inducement, port.

With the proliferation of digital devices, the devices have generated considerable additive white Gaussian noise while acquiring digital images. The most well-known denoising methods focused on eliminating the noise, so detailed components that include image information were removed proportionally while eliminating the image noise. The proposed algorithm provides a method that preserves the details and effectively removes the noise. In this proposed method, the goal is to separate meaningful detail information in image noise environment using the edge strength and edge connectivity. Consequently, even as the noise level increases, it shows denoising results better than the other benchmark methods because proposed method extracts the connected detail component information. In addition, the proposed method effectively eliminated the noise for various noise levels; compared to the benchmark algorithms, the proposed algorithm shows a highly structural similarity index(SSIM) value and peak signal-to-noise ratio(PSNR) value, respectively. As shown the result of high SSIMs, it was confirmed that the SSIMs of the denoising results includes a human visual system(HVS).

Objective : Due to a better understanding of the pathophysiology of posttraumatic stress disorder (PTSD) and the relative limitations in the treatment of patients with PTSD, a variety of medications and treatment algorithms for PTSD have been investigated. This study was conducted to investigate the trends in the pharmacotherapy used in the treatment of inpatients with PTSD at a single university hospital in Korea. Methods : Data from 75 patients diagnosed with PTSD according to the DSM-IV criteria from January 1998 to December 2007 were collected. Demographic data and clinical data, including medications prescribed, were investigated. Results : Thirty-three of the 75 subjects included in this study were male, and 42 were female. Considering psychiatric comorbidity, depressive disorder, cognitive disorder, psychotic disorder and anxiety disorder were reported in order. Approximately 97% of the subjects were treated with antidepressants, including paroxetine in 54.7%, and 24% of the subjects were treated with two different kinds of antidepressants. In addition, atypical antipsychotics were prescribed in 33.3% of patients, mood stabilizers in 17.3%, and anxiolytics in 94.7% of the subjects. Conclusion : In our study, various kinds of antidepressants were prescribed for most patients with PTSD. Antipsychotics and mood stabilizers were added to the treatment regimens of some subjects, and anxiolytics were added to the treatment regimens of most subjects. Despite its many limitations, this study shows the prescription pattern and trends in PTSD treatment in Korea. We hope that these preliminary data would be helpful for the development and integration of a practical guideline for the treatment of PTSD in Korea.
