Archival science is prior to explore meaning and role of record management in given environments rather than developing record management methodology. Electronic record environments don't merely mean to exchange record management medium from paper to digital. The most important point exploring in electronic record environments is not management skills or methods, but meaning of records and role of record management in contemporary society. All these days, however, the theories and methodologies has been developed focusing on written records and public records mainly in the deep-rooted influence of positivism. In such situations, the discussions of social memories can explore meanings and roles of record management in pluralistic society. Meanwhile, many articles in archival science has been widespread recognition that records will soon be just memories in terms of objective and neutral evidence. In recently, however, conviction on objectivity and neutrality of records has broken down by the influence of postmodernism on archival science. Therefore this article intends to explore the relationship between record and memory and to argue the roles of archival science for building social memories.

Recently, each country has been moving to introduce an LCA (Life Cycle Assessment) to regulate greenhouse gas emissions. The LCA is a mean of measuring and evaluating greenhouse gas emissions generated over the entire life cycle of a vehicle. Reliable data for each electric vehicle component is needed to increase the reliability of the LCA results. To this end, studies on life cycle evaluation models using blockchain technology have been conducted. However, in the existing model, key product information is exposed to other participants. And each time parts data information is updated, it must be recorded in the blockchain ledger in the form of a transaction, which is inefficient. In this paper, we proposed a DID(Decentralized Identity)-based data collection model for LCA to collect vehicle component data and verify its validity effectively. The proposed model increases the reliability of the LCA by ensuring the validity and integrity of the collected data and verifying the source of the data. The proposed model guarantees the validity and integrity of collected data. As only user authentication information is shared on the blockchain ledger, the model prevents indiscriminate exposure of data and efficiently verifies and updates the source of data.

Local culture is a cultural heritage that has come down from generation to generation in the natural environment of a region. It includes history, tradition, natural features, art, and historic relics. The Academy of Korean Studies has complied "The Encyclopedia of Korean Local Culture" using those local culture contents. Local culture content shave the features of documentary, such as authenticating the source, and managing hierarchy structure. Thus, to deal with local culture contents, a "circular knowledge information management system" is sought for that helps basic, fragmentary, and high-level information to circulate to create new knowledge information within the system. A user of this circular knowledge information management system is able not only to collect data directly in it, but also to fetch data from other database. Besides, processing the collected data helps to create new knowledge information. But, it's very difficult to sustain the features of the original hierarchy bearing meaning contained in the various kinds of local culture contents when building a new database. Moreover, this kind of work needs many times of correction over a long period of time. Therefore, a system in which compilation, correction, and service can be done simultaneously is needed. Therefore, in this study, focusing on the case of "The Encyclopedia of Korean Local Culture", I propose a XML-based digital compilation management system that can express hierarchy information and sustain the semantic features of the local culture contents containing lots of ancient documents, and introduce the expanded functions developed to manage contents in the system.

This study examined the satisfaction difference in the aspects of awareness, information quality, and availability in healthcare applications according to smartphone user's characteristics. Data collection was conducted between September 17th and September 21st 2014 on the 193 people who had used healthcare applications, and the data collected were analyzed with descriptive statistics, t-test, One-way ANOVA, and Kruskal-Wallis test using SPSS WIN 20.0. Differences in satisfaction of healthcare application were observed according to the general characteristics, and according to age, education level, and income, as well as for healthcare application use characteristics, according to operation system, total use period, the number of installed healthcare applications, the sources of main information, use frequency, and reasons of no use. To establish strategies for the effective spread of mobile healthcare and development and distribution of healthcare applications, it will be necessary to confirm smartphone users' characteristics and it is important to reflect them in the strategies. In addition, it is necessary to develop and implement a range of strategies to ceaselessly induce the users' motives of use and to improve their degree of satisfaction to secure the constant use of developed health care applications.

A study of the sanitary quality of Pacific oysters (Crassostrea gigas) and growing waters associated with raft culture in Burley Lagoon, Washington was conducted. The study was sponsored by the Agency for International Development of the U.S. Department of State. The results obtained in this study are as follows: The average values of temperature, salinity and turbidity in the water showed that the values of bottom sample were slightly higher than top samples. The difference was about $0.3^{\circ}C$ for temperature, $0.5\%_{\circ}$ for salinity and 0.1 JTU for turbidity. The changes of temperature and salinity by tide generally followed the tide cycle pattern. Sanitary indicator microorganism concentrations in top water were generally higher than those in bottom water. In general, the levels of mean coliform and fecal coliform MPN's varied inversely with tide level indicating that the sources of these groups of microorganisms are the fresh water streams flowing into the estuary. The $35^{\circ}C$ plate counts were more stable at different tide levels. Mean values of coliform and fecal coliform MPN's in oysters demonstrated that levels in top oysters were generally higher than those in bottom oysters. However, mean values of $35^{\circ}C$ Plate count in oysters did not show this pattern. The mean levels of both coliform and fecal coliform MPN's in oysters also correlated inversely with tidal level. The accumulation ratios of oysters obtained during the study period ranged from 8.6 to 19.7 for mean coliform MPN and 16.9 to 44.3 for fecal coliform MPN. According to the results obtained from present study, one suggestion could be of considerable importance for the sanitary operation in hanging culture of pacific oysters. The results indicate that harvest of the oysters at high tide would result in lower levels of indicator organisms in the shellfish.

In this study, open inquiry reports of 165 eighth graders in Daegu were analyzed in terms of content area, the types of inquiry hypothesis, and the types of inquiry variables. Before summer vacation, students learned about inquiry process and explored their own inquiry topic for two class hours. During summer vacation, students performed open inquiry including problem selection, designing and performing experiment, data collection, data analysis, and writing report. After the vacation, students submitted their reports, and answered to additional survey regarding the source of inquiry idea, the definition of hypothesis, and the most difficult step of inquiry process. As a result, chemistry was the most dominant content area of the reports and biology and life science were the next. 130 out of 165 reports included inquiry hypotheses, and most of them were predictive hypotheses. In many reports, dependent and independent variables could not be identified because of their ambiguity. However, inquiry variables described in experimental design, which were mostly categorical variables, were clearer than those described in inquiry subject and inquiry hypothesis. The most difficult step of inquiry process for students was to generate an idea for open inquiry.

A lab-scale vertical flow subsurface (VFS) wetland composed of three parallel columns with polypropylene synthetic fiber as main substrate was operated. Piggery stormwater diluted from swine excreta was fed to the wetland on the basis of three different hydraulic regimes or hydraulic retention time (HRT) of 2, 4, and 8 days with daily internal recirculation. Then, monitoring of common water quality parameters was carried out. Unexpectedly, an increase of effluent COD concentration accompanying the appearance of foams was observed during a distinct period in the wetland with HRT 2, 4, and 8 days, successively. Subsequently, a series of experiments was conducted to investigate the origin of the foams. Foams and the increase of COD concentration were found to be induced by the release of organic matter from the synthetic polypropylene fiber which was fed with piggery stormwater. Meanwhile, nitrogen removal was found to be enhanced during a period which overlapped the distinct foaming period signifying that foaming played two important functions in biological nitrogen removal. Foams which form rapidly and then burst easily could hold up and then release oxygen for nitrification. Foams which contain organic surfactants could serve as carbon sources for denitrification as well. Hence, nitrogen removal was enhanced during the foaming stage. After that, COD concentration decreased slowly to a level prior to the foaming stage, and nitrogen removal efficiency declined as well.

The purpose of this study is to investigate the determinants of the quality of Web-based legal information services and their significant influences on the user continuance intentions. Based on the main dimensions of the SERVQUAL, this study conceptualizes five dimensions of reliability, assurance, design, empathy, and responsiveness. It measures the level of expectation and satisfaction on the basis of these five dimensions. Regression analysis was conducted to extract and analyze the determinants of the service quality and the factors affecting continuous intention. The level of legal information service quality is superior in empathy, responsiveness, and design category, but it is relatively insufficient in reliability and assurance category. In the reliability category, the relevance of the search results was an issue. The problems related to the authority and information sources were recognized as important. Reliability implies that there is a relatively close relationship between empathy and responsiveness, and that it is necessary to improve the quality of contents such as empathy and responsiveness in order to increase reliability. In order to increase the ongoing use of legal information services in the future, it is more effective to make sure that assurance is top priority.

Many countries have established eBook standards adequate to their environments. In USA, OEB PS is announced for distribution and display of eBooks, in Japan, JepaX is announced for storage and exchange, and in Korea, EBKS is made for clear exchange of eBook contents. These diverse objectives lead to different content structures. These variety of content structure will cause a problem in exchanging them. To correctly exchange eBook contents, the content structure should be considered. So, In this paper, we study conversion methods of standard eBooks contents based on Korean eBook standard, with contemplating content structure. To convert contents properly, the mapping relations should be clearly defined. For this, we consider standard's structure and extension mechanisms, and use path notations and namespaces for precise description. Moreover, through analysis of each mapping relationships, we classify conversion cases into automatic, semi-automatic, and manual conversions. Finally we write up conversion scripts and experiment with them.

This study traced the origin and transformation of word library linked with archives in the ancient Near East, and Greece and Rome. First, the word library has two origins. One is derived from the Latin bibliothēkē from the ancient Greek βιβλιοθήκη. The first trace is Pollux's Onomasticon in the second half of the 2nd century, and if considered as a set of literature texts, it is Lipsius's De Bibliothecis Syntagma in 1602. The other was established as an library in the early 14th century after Latin libraria (or librarium) was translated into Old French librairie (or librarie). The word library was coined by Chaucer in 1374. Second, the clay tablet repository that existed in the ancient Near East is close to an archive, but the official name is unknown. However, the Ashurbanipal clay tablet archive is far from the principle of respect for original order and origins emphasized by the archivists, so it is not a royal archive, but a prototype of the royal library. And the official name of the Library of Alexandria was 'Βιβλιοθήκη της Αλεξάνδρειας', and then it was changed to 'ALEXANDRINA BYBLIOTHECE'. Third, In ancient Greece and Rome, archives and libraries were separated. Greece libraries were at the level of a small libraries attached to gymnasiums, and had few independent titles. The names of the Roman libraries often attached to the public baths were mixed with βιβλιοθήκη and Bibliotheca. Finally, the ancient library was succeeded to the cathedral bibliothek, and was transformed into 'bayt al-hikmah' in the Islamic Empire. In Japan, China, and Korea, Japanese-Chinese word library was accepted at the end of the 19th century, but there are many issues that require follow-up research.
