We investigated 'Song of the Sky Pacers, Adopted to the New Methods'(新法步天歌), the latest version of Joseon's 'Song of the Sky Pacers'(步天歌). Due to the influence of new knowledge on Chinese asterisms imported from the Ching dynasty, 'Song of the Sky Pacers with New Star-Charts' was written in the eighteenth century. However, the disagreement between song and star-charts was causing confusion in practical applications such as Joseon's national examination for selecting astronomers. In order to improve this situation, Royal Observatory of the Joseon dynasty (觀象監) published 'Song of the Sky Pacers, Adopted to the New Methods' based upon star-charts and song in the Sequel of I-Hsiang-K'ao-ch'eng (欽定儀象考成續編). The New Song was edited by a middle-class professional astronomer Yi Jun-yang (李俊養), and corrected by a nobleman Nam Byeong-gil (南秉吉). We establish a brief biography of Yi Jun-yang. The New Song preserves the genuine characteristics of previous Joseon's Song including the format of title of each lunar mansion and description on the location of the Milky Way in the asterisms. The description of the Milky Way was newly written based on the data in volume 31 and 32 of the Sequel of I-Hsiang-K'ao-ch'eng.

This study aimed to investigate the current uses of subheadings that appear in medical science journal abstracts and to discuss its potential implications for medical science from the perspectives of library and information science. To conduct this study, the following nine sub-fields in medical science were selected: cancer, ethics, genetics, infectious disease, neurology, pediatrics, immunology, psychiatry, and cardiology. Random sample data were drawn based on the years 2010 to 2015 from the PubMed database. This study investigated the extent of the uses of subheadings, variants of subheadings, and common formation of subheadings with the help of a frequency analysis. The specific findings of this study are summarized as the following: 1) more traditional abstracts are used across almost all sub-fields of medical science; 2) on average, 4.1 subheadings were used in the sample dataset; and 3) the most frequently used set of subheadings is OBJECTIVES, METHODS, RESULTS, and CONCLUSIONS. This subheading set appears to be the de facto standard across all medical science journals. The analysis of subheadings in structured abstracts and the issues raised in this study can be beneficial for journal editors and other academics in medical science as well as library and information science.

Human has noticed a beautiful natural scenery and appreciated it as a scenic site by giving meaning to it and evaluating it. How the beautiful natural scenery was appreciated as a scenic site depends on natural features, social and cultural environments, and the current of the times. Mt. Jiri is the highest mountain in inland South Korea and keeps ancestors' history and culture intact. Joseon Dynasty literary men frequently mentioned Mt. Jiri as a tourist attraction where they could pursue and share their studies against its beautiful natural scenery. The countless literary men visited Mt. Jiri and some of them left their journeys as travelling records. This research aimed at apprehending travel routes of Chunwang Peak of Mt. Jiri based on the contents of travelling records and investigating the scenic site value of scenic resources as the literary men in Joseon Dynasty recognized. The scenic resources of Mt. Jiri were related to the change of the reason or motivation of person who climbed and it should be noted that there was a change of reason or motivation in climbing Mt. Jiri from a following of master's paths to discovery of a new trails. Thus, even if there was a difference in reason or purpose of natural scenic beauty, the concept of scenic sites of the past and the present day should be included into the extended meaning of scenic sites. This research aimed the routes of well-known literary men need to be developed as programs utilizing "the concept of ancient sages' footprints" and the development of these contents shall be used for vitalization and self-support of a regional economy.

Among the seven taxa of the genus Vigna, Leguminosae vegetated in Korea peninsula, only two taxa, V. unguiculata subsp. unguiculata and V. vexillata var. tsusimensis, are recognized in Vigna. The rests are still remained in the genus Phaseolus in many floras and illustrations of Korea although they were placed into the genus Vigna by Verdcourt in 1970. There has been misidentification between V. angularis var. nipponensis and V. nakashimae because of their similar morphological characters and habit. It was also found that V. nakashimae has not been recorded in many floras. Objectives of this study are 1) to discuss the taxonomic differences between Vigna and Phaseolus, 2) to have a recommendation for using correct scientific names of Vigna taxa, 3) to discuss the taxonomic characteristics of the subgenus Ceratotropis, and 4) to provide a simple taxonomic key of V. angularis var. nipponensis and V. nakashimae.

It is well known that the improved methods of the estimation of the service power margin is necessary to design a optimum ship and to operate economically a ship. Unfortunately, most conventional methods of the predicting of the service power margin are not so accurate that attention should be payed to improve this. From this overview, it is importance with. the effects of waves, as recommended by the 15th and 16th International Towing Tank Conference in 1978 and l981. However the progress of research in this field is very slow mainly since it is taken so long time to take data about hull roughness according to ship ages. For instance, it would be taken 17 or 25 years to measure ideally the data for a ship. Moreover it would be also necessary to take data for many types of ships to lead a general solution. A relationship between roughness and ship age are studied in this paper considering full scale data. A comparison is also made between the effects of hull roughness and of weather at sea for the ship.

The social demands to conserve the geological outcrops with important scientific values are increasing. Accordingly public programs such as national geopark are recently established. In this study, outcrops with geological values in the Dusong Peninsula geosite of the Busan National Geopark are investigated in details with a discussion in the aspects of geoheritage values. The Dusong Peninsula is located in the late Cretaceous Dadaepo Basin interpreted as an intra-arc pull-apart basin extended in the Cretaceous Yucheon Subbasin. In this area, a number of noticeable geological records, such as andesitic sills, lower Dadaepo Formation, paleo-seismites, clastic dikes, compound calcrete deposits, syn-depositional normal faults, and unconformity between basin-fill and basements, are observed. Considering their unique geological significance, the strategic plans for their conservation and management should be urgently provided.

Researchers have continuously investigated the issues of customer satisfaction, customer loyalty, and repurchase intention of customers in Internet shopping malls, a fast growing e-bisiness model in Korea. At present, most Internet shopping malls in Korea offer similar services to their customers. This has caused intense industry competition, and the Internet shopping malls have made significant investments into their websites in order to remain attractive to their customers. This research examines the relationships among website charateristics, customer satisfaction, loyalty, and repurchase intention. Website characteristics include context, commerce, connection, communication, contents, community, and customization. We have used data from a field study of 662 individuals to test the proposed model. The results of this research show that among the 7 website characteristics, context, communication, content, and commerce are the significant determinants of customer satisfaction. In turn, customer satisfaction increases customer loyalty and repurchase intention. These findings have important theoretical and practical implications, which are discussed in the paper.

Recent research on organizational innovation, such as. new managerial processes, practices, suggests it can be an important source of firm's competitive advantage. The challenge is not only offering new products and services, but also changing the nature of management within organizations. In this study, we focus on management innovation at the organization level and investigate the role of transformational leadership behavior as a key antecedent. Transformational leadership may complement an organization''s increasing rigidity by maintaining a sense of meaningfulness in members of the organization, which may be more flourishing to organizational innovation. Due to its prominent role within organizations, CEO has the ability to greatly influence management innovation. In particular, we focus on leadership behavior and examine transformational leadership of CEO. Additionally, as contextual variables like organizational structure(complexity, formalization, centralization) may influence the impact of transformational leadership, we investigate its moderating role. Findings show that transformational leadership behaviors positively contribute to organizational innovation. In addition, our study indicate that less complex, less formal and less central, organizations have benefit more from transactional leadership in strengthening organizational innovation.

As radiation therapy is one of three major cancer treatment methods, many cancer patients get radiation therapy. Because of the invisible and scattering characteristics of radiation, it is impossible to identify the quality and the amount of radiation and secondary cancer could be induced by scattered radiation. Because of advanced technique of radiation therapy and the reasons mentioned above, quality assurance of radiotherapy machine should be performed completely. International organizations such as International Atomic Energy Agency (IAEA), American Association of Physicists in Medicine (AAPM) suggest report of quality assurance to recommend united method of radiotherapy machine quality assurance. Domestic society of medical physics, however, is too small to make such a report, domestic hospitals selectively choose some of contents in global suggestions. As there are no suggestions for domestic hospitals and global suggestions are being updated, we did a survey about quality assurance for radiotherapy machine. The questionnaire is composed of possession of radiotherapy machine, items performed for quality assurance and manpower, etc. 37 of 72 hospitals answered to survey. These results could be used for making domestic standard quality assurance procedure.

This paper is to analyse empirically using the data collected from Korea portal Naver's ad management system and show online ad platform may not be two-sided market. It is aim of this study to propose the appropriate approach to define the market, based on the empirical result. Here are two research questions to be reviewed. First, is there any consistency between business model of search advertising and definition of two-sided market which Rochet-Tirole proposed in 2006? Second, do indirect network externalities exist significantly in search advertising market? if so, this study is going to estimate the level of it through empirical measurement. Based on Luchetta's paper which suggested that google may be one-sided market, it performed the correlation & regression analysis to prove his suggestion. The result is that online search advertising costs increased by more than 50 won when advertisers increased by one unit. However, there was no significant correlation and regression between the search frequency and online search advertising cost. It means that there is little possibility to identify two-sidedness in online search advertising service(market) because of no(or little) indirect network externalities which are a necessary condition for two-sided market. This result has three implications, such as the availability to adapt traditional market definition tools to online search advertising market, the possibility enhancement to find the fundamental competition elements in defined market and promotion of the powers of persuasion in competitive market reality. It is significant that the gap between legal scholars including regulatory practitioners and economists can be overcome to some extent. who have shown the different perspective on the two-sided market.
