Social network service is defined as an online service or communication service based on social relations among people applied the concept of social network. Social collaborative service included in social network service is characterized by the new value of modified content or recreated content made through collaborative creation process between members of the group. It has the remarkable merits such as sharing and collaboration. But, at the same time, it has the latent problems such as content reuse or copy that is not allowed for members to use. It has been emerged that UCC which is a typical example of recreated or modified content has the copyright issues in both creation and publishing step. To resolve this matter, we don't have many appropriate methods except CCL so far. So, in this paper, we define the problem and implement the UCC metadata manager to control metadata reflecting the feature of UCC. We draw the reference metadata element to identify original content utilized re-creation process. After that we define the R.Metadata Loader module based on the use case. Finally, the proposed UCC metadata manager provides the information of referenced content and lets us to identify the relationship between reference contents. So as to implement prototype, we use Kaltura which is CMS using open source and obtain functional extensibility of metadata manager by using open API.

According to the study of Jik-Ryoung(直領) consulting chronicles of the Chosun Era, Jik-Ryoung had been worn for various uses as official outfit, ordinary attire or clothes for the celebration of their coming of age, wedding ceremonies, funeral rites, and religious ceremonies, etc. from the beginning to the end of the Chosun Era. The conclusions are shown briefly as follows. 1. There are several terms of Po(袍) related to Jik-Ryoung in the chronicles under the name of Jik-Ryoung Ui(直領衣), Ui-Sal Jik-Ryoung(衣撒直領), and Jik-shin(直身). Jik-Ryoung Ui is the other name of Jik-Ryoung that they called it when it was used for funeral rites and religious ceremonies. The chinese Ye-Sal(曳撒) was called the Ui-Sal Jik-Ryoung in Korea, but this is different with Jik-Ryoung regarding its divided up and bottom style. Jik-Shin is almost same as Jik-Ryoung. 2. During the latter period of the Chosun Era, we can find diferent frequency in use of the Jik-Ryoung. Jik-Ryoung was shown constantly in the cases of that ding, Chinese Prince and lower-level constantly in the cases of that king, Crown Prince and lower-level officials wore it for funeral rites and lower-level officials, artisans, merchants, humbles and slaves wore it for official outfit. Uses of the Jik-Ryoung increased for military officers'outfits, in contrast to decreasing of uses for ordinary attires of king, Crown Prince, and the commons, and official outfits of civil officials. 3. These different aspects mean the change of estate and role. For the basic four ceremonial occasions the ceremonies of coming of age, marriage, funeral, and ancestor memorial-, it appeared constantly. Therefore the social role had been maintained also by then. As an official garb, the role for official uniform of petty official maintained by the end of the Dynasty. But from the latter 1600's to the former 1700's, the roles for official garbs of civil officials and military officers decreased and increased respectively. Before the Hideyoshi's Invasion of Korea in 1592, ordinary social clothes had orders by people's social status who wore them ; those were Dan Ryoung(團領), Hong Jik Ryoung(紅直領), Jik Ryoung(直領), Cho'l Rick(철릭) in the order named. After the war, various Po(袍), Shim Ui(深衣), Jung Chi Mak(中致莫), Chang Ui(　衣), Jang Ui(長衣), Ju Ui(周衣) and so on had been worn until the King Young Jo(英祖)·Jung Jo(正祖) period. In result, the social role of Jik-Ryoung was reduced as the uses decreased more and more. For a mourning dress, it had a same aspect as the case of ordinary social wear. 4. Considering the color, they used blue for the clothes for doing-up-the-hair ceremony, white for mourning clothes, and white, black for ancestor memorial ceremony clothes. On the official outfits of officials, dark blue and black were used mostly. And lower-level officials'clothes had white, red, and green on them. They used red and green for the plain dresses. 5. Examining the materials, clothes for the celebration of one's coming of age were made of high quality silks, Kwang Hwa Dan(廣禾緞). Also, they made clothes for funeral rites of rough and thick linen, and made clothes for religious ceremonies of linen and hemp. The official outfits were made of practical materials like cotton, hemp and ramie. Cotton, pongee and satin were used to make ordinary attire.

This study aimed to analyze open access features of 1,890 Korean scientific journals registered in the Korea Citation Index (KCI). To this end, this study classified open access features of the target scientific journals into two main aspects, free access and free redistribution. The analysis results indicated that the target scientific journals had strong free access aspects. Based on websites, 67% of the target scientific journals allowed for free access without a login process and based on free database, 48% provided free access. On the other hand, the target scientific journals had weaker free redistribution aspects compared to their free access aspects. Only 14% of them offered the CC (creative commons) license. Another finding was that there were clear differences in open access aspects by academic field. Medicine, pharmacy, natural science, agriculture, fisheries, oceanography, and engineering had stronger open access aspects than humanities, sociology, arts, physical education, and interdisciplinary science. It appears that the difference was caused by the presence or absence of organizations supporting distribution of scientific journals of the fields concerned. To narrow the gap, it is recommended that the open access governance system is established to set up open access policies for Korean scientific journals regardless of academic fields and to support them.

In early 2019, Korea passed the law that introduced data management plan policy similar to those adopted by national funding agencies in other countries. In anticipation of developing research data infrastructure and support services, this study analyzed Australia's relevant policies and policy instruments. A number of face-to-face interviews with the experts at the national funding agency, a national research data agency and a number of research libraries, along with focused literature analysis. In Australia, the 2015 Public Data Policy is applied to research data from publicly funded research. Research data management and sharing is recommended but not required by the national funding agency it its policy documents. Australian National Data Service(ANDS), Australia's national research data agency, is an important component of the national research infrastructure. ANDS plays a wide range of roles including research data platform development, education and training, policy support, and funding agency for small-scale R&D. Some of the Australian research libraries have developed in-house systems for research data storage and publishing. However, there is no significant demand for research data service as yet. Lessons learned include the following: ensuring transparency and predictability of research data policies, establishing a dedicated agency responsible for research data platform development and training, and cultivating data capabilities at research libraries.

Streptococcus spp. of bacterial pathogen of fish were isolated from the cultured flounder (Paralichthys olivaceus) in fish farm of Jeju Island. Clinical signs of the infected flounder which are the most commons symptoms are as follows: erratic swimming, darkening of the body colour, unilateral or bilateral exophthalmia, corneal opacity, hemorrhages in the opercular and the bases of the fins, and the ulceration of the body surface. Biochemical characteristics of pathogenic fish Streptococcus spp, were gram positive, spherical form, catalase negative, oxidase negative and $\beta$-haemolytic, respectively, The viable cells counted from the tissue of the diseased flounder were the largest in the order of the ulcer, the kidney, the blood and the brain, The drugs used were ampicillin, ciprofloxacin, doxycycline, gentamycin, tetracycline, erythromycin, streptomycin and oxytetracycline, Streptococcus spp. were found to be sensitive to ampicillin, ciprofloxacin, doxycycline and gentamycin, but were resistant to tetracycline, erythromycin, streptomycin and oxytetracycline. The pathogenicity of Streptococcus spp. on the cultured flounder with an abdominal cavity injection was high. The haemolytic activity of the toxin against the sheep red blood cells reached the maximum after 30 min incubation at $37^{\circ}C$ or $50^{\circ}C$. The toxin showed highest activity at pH $5.5\sim6.5$.

This study explores the influence of cognitive and affective trust on IT service project performance. Technology and Business expertise are posited as antecedents for cognitive trust which social bonding and relationship conflict as over for affective trust. Communication is posited as the commons antecedent for both kind of trust. A study was administered among IT Project leading in different projects. Analysis of 169 data point in general supports the research model. For building cognitive trust, Communication is formal to be must important while business expertise the second and technical expertise the third. For affective trust, the influence of antecedent are relatively smaller than the case of cognitive trust. For project performance, Cognitive trust seem to have stronger impact as IT may have direct impact as well as indirect impact via affective trust. Findings trust though the impact is smaller than the cognitive trust. In practice, this means to maintain Balanced approach in fostering trust-cognitive and affective.

This study was conducted to evaluate the effects of Platycarya strobilacea S. et Z. (PSE) extract on mouse hair growth and to determine the mechanism of action of PSE. PSE was purchased and its antioxidant activities, such as electron donating ability, total polyphenol content, and flavonoid content were tested. Toxicity during topical treatment was determined by the CCK-8 assay, a cell viability test. Fifteen 4-week-old male C57BL/6 mice were assigned to receive one of three treatments: dimethyl sulfoxide (negative control), minoxidil (positive control) or PSE. Test materials were topically applied to the shaved dorsal skin of each mouse daily for 3 weeks. After 21 days, we observed skin tissue hair follicle morphology and length, mast cell number, and stem cell factor (SCF) expression using hematoxylin and eosin (H&E), toluidine blue, and immunohistochemical staining, respectively. Furthermore, the expression of cytokines involved in hair growth [i.e., insulin-like growth factor (IGF)-1, keratinocyte growth factor (KGF), and transforming growth factor (TGF)-${\beta}1$] was determined by PCR. PSE was found to have very high antioxidant activity. The cell viability rate of PSE-treated mice was markedly higher than that of mice in the control group. We also observed an increase in hair follicle length, strong SCF staining, and a decrease in mast cell number in the PSE group. In addition, PSE-treated mice had higher IGF-1 and KGF expression and lower TGF-${\beta}1$ expression than mice in the minoxidil-treated group. These results suggest that topical application of PSE promotes hair growth by intensifying SCF, suppressing mast cell production, and increasing hair growth-promoting cytokine expression.

This paper is to consider the development process of conflict between Daegu and Gumi which has been arisen from Daegu city's plan of relocation of water intake plant. It first argues that water is a major common and public resource which is circulated through the social process as well as the natural one, and hence that conflicts within or between regions due to its allocation should be resolved or managed by construction of collaborative governance in which all stake-holders participate. In particular, it is pointed out that collaborative governance would be not only oriented to a normative goal, but also be mobilized as a strategic means. On the basis of this conceptual consideration, this paper explores the development process of conflict caused by Daegu city's plan of relocation of water intake plant, and analyze the starting conditions and deliberation process of the public-private committee which has been constituted through a consensus between Daegu and Gumi city government. It concludes that the current interruption of the committee has happened, because it has been mobilized politically as a strategic means for regional hegemony, not as a normative one to resolve the conflict.

This paper aims to clarify the process of institutionalization of customary land ownership along with the expansion of coffee plantation in Dak Lak Province, Vietnam. Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production. The expansion of coffee plantation in Dak Lak have brought a severe competition of land resources, and resulted in the transition of land ownership scheme from customary commons by ethnic minorities to those of exculsive private assets which is secured by the state. Institutionalization of customary land ownership in Dak Lak, however, was differently happened according to the geography from the center of state power as well as the value of land resources. In this paper, the authors argue that institutionalization of customary land ownership in Dak Lak was a result of compromising between statemaking process in the frontiers and "everyday resistance" of ethnic minorities, comparing 3 geographically different ethnic minorities' communities.

Different from the traditional client-server model, it is possible for participants in a cooperative distributed system to get quality services regardless of the number of participants in the system since they voluntarily pool or share their resources in order to achieve their common goal. However, some selfish participants try to avoid providing their resources while still enjoying the benefits offered by the system, which is termed free-riding. The results of free-riding in cooperative distributed systems lead to system collapse because the system capacity (per participant) decreases as the number of free-riders increases, widely known as the tragedy of commons. As a consequence, designing an efficient incentive mechanism to prevent free-riding is mandatory for a successful cooperative distributed system. Because of the importance of incentive mechanisms in cooperative distributed system, a myriad of incentives mechanisms have been proposed without a standard for performance evaluation. This paper draws general incentive design considerations which can be used as performance metrics through an extensive survey on this literature, providing future researchers with guidelines for the effective incentive design in cooperative distributed systems.
