The year 2018 is the $50^{th}$ anniversary of scientific ocean drilling. Nevertheless, we know more about the surface of the moon than the Earth's ocean floor. In other words, there are still no much informations about the Earth interior. Much of what we do know has come from the scientific ocean drilling, providing the systematic collection of core samples from the deep seabed. This revolutionary process began 50 years ago, when the drilling vessel Glomar Challenger sailed into the Gulf of Mexico on August 11, 1968 on the first expedition of the federally funded Deep Sea Drilling Project (DSDP). DSDP followed successively by Ocean Drilling Program (ODP), Integrated Ocean Drilling Program (old IODP), and International Ocean Discovery Program (new IODP). Concerning on the results of scientific ocean drilling, there are two technological innovations and various scientific research results. The one is a dynamic positioning system, enables the drilling vessel to stay fixed in place while drilling and recovering cores in the deep water. Another is the finding of re-entry cone to replace drill bit during the drilling. In addition to technological innovation, there are important scientific results such as confirmation of plate tectonics, reconstruction of earth's history, and finding of life within sediments. New IODP has begun in October, 2013 and will continue till 2023. IODP member countries are preparing for the IODP science plan beyond 2023 and future 50 years of scientific ocean drilling. We as IODP member also need to participate in keeping with the international trend.

With the 500th anniversary commemoration of Gerard Mercator's birth in 2012 now passed, there is the possibility that his name will fade back into obscurity. This would be both unfair and pitiful, because Gerard Mercator's name should be highly regarded as one of the principal contributors to navigational science and the promotion of marine safety. An accomplished cartographer, in 1569 Mercator published a remarkable 18-folio world map, depicting the then-known world in a new format with straight rhumb lines. While this distorted the size of land masses, particularly in higher latitudes, this new projection made navigation much easier for now all sailors had to do was to draw a straight line between two points to plot their course. Mercator clearly had this navigational benefit in mind, though his contemporaries did not immediately recognize its value. It wasn't until after Mercator's death, when Edward Wright (1599) and Henry Bond (1645) used and explained the new projection and demonstrated the use of straight rhumb lines in navigation that the Mercator projection became the standard for sea charts. Today, 450 years later of his death, electronic charts still rely on the projection Mercator invented and developed, confirming his position as a giant in the history of navigation. This paper introduces his life and work, detailing the importance of the 1569 world map and its contribution to navigational science and safety.

Although National Health Insurance(NHI) in the South Korea has guaranteed access to health insurance coverage to virtually all the people, a significant portion of out-of-pocket spending can create substantial financial burdens for some beneficiaries, particularly those with low incomes. Previous studies have estimated the magnitude of out-of-pocket spending by types of chronic illness or in- and out-patients. Prior estimates, however, have not given a complete picture of the impact of health care costs on lower-income populations. The result from this study shows that 20 percent of beneficiaries in the lowest-income quintile spent more than twelve percent of their household equivalent income out-of-pocket health services, whether they were enrolled in a Health care services or not. In comparison, the beneficiaries in the highest-income quintile level spent only 2 percent of their income out-of-pocket on health care. Also, the regression analysis suggests that age, household income, number of chronic illness, type of hospital in addition to the number of usage may affect the size of out-of-pocket spending.

This year of 2009 is the 420th anniversary for the high treason case in the year of ox (year 1589). Until now, there is an endless discussion still progressing about Jeong, Yeo Rip. The evaluation of such individual varies widely according to the viewpoint of each individual. However, the problem is that such confusion or issue is exaggerated under the pretense of his idea's progressivity. The true identity and ideology of Jeong, Yeo Rip will become clear once we review such fact from the origin. This article considered abstract and ideological evaluation of occasion and took its approach thoroughly based on the historical research of literature. Until now, some parts academic world have denied and argued about the fabrication about every details of Jeong, Yeo Rip and event of high treason in the year of ox while accepting the habitual sentence spoken by such individual without a doubt. They have exaggerated Jeong, Yeo Rip as an 'Incompleted Revolutionist' or 'Individual of Revolutionary Ideology'. However, it is imprecise to speak about the terminology of 'Revolutionary'. His ideology is simply elucidating the principal of original Confucianism or a new interpretation of the principle of Confucianism. Jeong, Yeo Rip wanted to contradict the system of national school based on the Zhu-xi's ideology and returned to the principle of original Confucianism. His idea of utopia based on the Confucianism arouse out of the intention of reviving the spirit of original Confucianism. His antagonistic propensity to Zhu-xi's ideology or political idea has transcended the principle of justification based on Sung Confucianism and was also logical and realistic. He was forced on to the deadly circumstance since the society of Joseon Dynasty couldn't accept such logical and progressive idea and deemed him to be nothing more than a disturbing element for the society.

We studied the fishing ground of a yellowtail and oceanographic conditions around Chujado and Marado around Jeju Island from autumn to winter. Also we investigate the forming mechanism of fishing ground around Marado, which shows the best catch of yellowtail near Jeju island. The obtained results are summarized as follow ; 1. When the high temperature water about 15.0∼19.0 in depth of 50m distributed around Chujado and Marado, the fishing ground of Yellowtail is shows a good catch. On the contrary, when the low temperature water about 11.0∼14.0 is shows a poor catch. 2. Fishing grounds of yellowtail by handline fishing are formed with a school of Yellowtail migrating southward from the coastal sea of Korea and slaying around Marado to winter and spawn due to following factors. Firstly, a front of temperature and salinity is formed between inshore water and oceanic water around Marado. Secondly, small-size eddies and excellent horizontal and vortical mix which is created by strong tide and geographical features including irregular underwater ground and an isolated island. An abundant school of yellow tails stays in front of the tide where a good fishing ground was made.

As government research and development projects become more important, such as the creation of future-oriented growth engines and expansion of budgets, the future vision of R&D is presented through paradigm shifts such as efficiency, investment direction and strategy. On the other hand, research and interest in sanctions are poor, and this paper examines legal grounds, comparative analysis of laws, and cases outside the country, draws implications for domestic applications, have. In addition, we will contribute to the prevention of damages caused by neglect, or the transparency of the execution of research funds. This study was conducted by comparing the characteristics of government R&D and sanctions with the sanctions for the top three R&D investment related SMEs. In Korea, starting with the introduction of sanctions in 2001, the moral hazard of research and development has been prevented through the cumulative violation of aggravation, expansion of the period of restriction of participation, and the introduction of a strikeout system. Nevertheless, fraudulent use of business expenses is constantly being detected. In order to ensure maximum autonomy and stronger responsibility than strong institutions, the willingness of the researchers to execute transparent business expenses, the moral approach to public resources, Precedence of recognition conversion is important.

This study aimed to analyze the usage behaviors of university students seeking and sharing everyday life information through an online community called Everytime. The study was designed based on everyday life information-seeking and activity theory models, and students from various universities were interviewed using a qualitative research method. Findings showed that Everytime users perceive Everytime as a valuable online community for pursuing and sharing everyday life information. It was primarily used to search for university life information, such as academic calendar, class, and graduation, and health, restaurants, and housing. In the case of the freshmen and sophomores who entered during the COVID-19 pandemic, their dependence on Everytime was high, and juniors and seniors who experienced university life before COVID-19 also responded that Everytime is one of the essential sources of information in university life. Although Everytime provides quick and valuable information, users mentioned the moral hazard as a major factor hindering the active use of Everytime. The results of this study are expected to be used as primary data for informatics research on the online community of college students and the development and operation of online communities for university students.

As the number of reported injuries has tended to increase over time, large hospitalization expenditure from excessive medical treatments and hospitalization, and insurance frauds associated with moral hazard in minor collisions have caused a global societal problem. Many occupants of rear-ended vehicles involved in rear-end collisions complain of whiplash injury, which is also known as neck injury, without any anatomical and radiological evidence. With only clinical symptoms, stating that a whiplash injury is a type of injury defined by the Abbreviated Injury Scale would be difficult. Therefore, this study focuses on minor rear-end collisions, where the rear-ender vehicle collides with the rear-ended vehicle at rest. The mathematics dynamic model is employed to simulate a total of 100 rear-end collision scenarios based on various weights and collision speeds and identify how the weights and speeds of both vehicles influence the risk of whiplash injury in occupants involved in minor rear-end collisions. The possibility of an injury is very high when the same-weight vehicles are involved in accidents at collision speeds of 15 km/h or higher. The possibilities are 36% and 84% with collision speeds of 15 km/h and 20 km/h, respectively, if weights are disregarded.

This year marks the 20th anniversary of the enactment of legislation related to records in Korea. The Public Records Management Act of Korea deals with the entire process from production to classification, transfer, and utilization for all records. Recently, the National Archives of Korea is in the process of discussing amending laws to implement records management innovations. It is necessary to take a look at the cases of advanced countries abroad, which have a long tradition of Archival management and focus on preservation records. In this study, Germany's "Federal Archives Act" was targeted. Germany is regarded as a country with a long tradition of managing preservation records. Especially, we have something in common that has experienced the history of division like our country. For the research results, each clause of Germany's "Federal Archives Act" was to be analyzed to understand Germany's Archival Management System. As a country that has experienced the division of Germany and unification, it maintains Archival management after unification. Therefore, we drew on the characteristics of Germany's Archival management law and system and studied what implications could be given to our country.

The purpose of this study is to examine the influence of the ownership structure of unlisted firms on KOSDAQ listing. There are few studies analyzing the characteristics of listing success based on ownership structure. For startup executives, there is not enough data to refer to the ownership structure that can increase the possibility of listing. This paper examines the effects of ownership structure on IPO success through comparison between listed successful and failed companies among the companies in application for KOSDAQ listing eligibility review. The major findings are as follows; (1) Venture capital investment and shareholding have a statistically positive effect on the success of KOSDAQ listing. This results indicate that the venture capital's investment alleviate the problem of information asymmetry, and it is a valid signal for market participants. The result means the role of venture capital seems to be important when companies are listed on the KOSDAQ. (2) The largest shareholder's stake has an inverted-U shape relationship with listing success. In other words, the ownership concentration mitigates moral hazard problem, which leads to listing success. However, if the ownership concentration exceeds a certain level, the chances of success in listing will decrease due to concerns over the pursuit of private interests. The result suggests that the largest shareholder's stake reduce agency problem. This study academically contributes to the existing literature by demonstrating the ownership structure affects IPOs, and explaining the results based on agent theory and signal theory. Our results provide practical implications for companies preparing for an IPO on the KOSDAQ.
