The study conducted Comparative Analysis on the difference of College Scholastic Ability Data divided by type of admission process through the mileage program. Analysis result in following sequence. Leadership and relationships : CSAT(CSAT) > TOSR(subject), CSAT(CSAT+TOSR) is lower than each types ; mainly TOSR(total), TOSR(subject), CSAT(CSAT). Global : CSAT(CSAT+TOSR) & CSAT(CSAT) is higher than mainly TOSR(total) & TOSR(subject). Career and job search : TOSR(total) & TOSR(subject) is higher than mainly CSAT(CSAT+TOSR). Sum of mileage score : CSAT(CSAT) is higher than TOSR(subject) & CSAT(CSAT). Given this as a result, If you look simply at the activities of joint participation of leadership and relationships, student of mainly TOSR(total) admission do well college life with existing research. But with analysis results of K-Leader mileage this research shows that students of mainly CSAT(CSAT) admission do well college life. * CSAT(College Scholastic Ability Test), TOSR(a transcript of school records)

The purpose of this study was to investigate older people's planning for estate distribution by examining the factors associated with their will-holding status. This study used data from the 1994 Assets and Health Dynamics among the Oldest Old (AHEAD) Survey, Wave One. The objectives of this study were (a) to establish profiles of older people who have a written will and to compare their financial portfolios across will-holding status; (b) to identify factors that influence the decision to make a will, and (c) to draw implications for family economists, financial educators, planners, and policy makers. The results suggested that a household's financial resources (i.e., liquid and illiquid assets, housing equity, and household income) positively influence the probability of having a will. Older people who resided in a community property state and who were in poor health were less likely to be will-holders than their counterparts, holding financial resources and other variables constant. Demographic characteristics such as age, education, and race, and behavioral characteristic also were significant determinants of the likelihood of having a will. Volunteer participation and charitable contribution, which are proxies for altruism, increased the likelihood of having a will. The probability of having a will also was higher among those who had life insurance and had gwen inter-vivos gifts of more than $\$5,000$ to their children or grandchildren in the past 10 years. On the other hand, the likelihood of having a will declined with increasing number of biological children. From the findings, implications for financial planners and educators were suggested along with directions for future research.

In this paper, we describe a compensation method of diurnal effect which is one of the factors giving large effect on the performance when using ground-wave signals like Loran-C for a backup and substitute navigation system of global satellite navigation system such as GPS, and currently many researches of the topics are doing in USA and in Europe. In order to compensate diurnal effect, we find periodic frequency components by using the Least Square Spectral Analysis (LSSA) method at first and then compensate the effect by subtracting the estimated compensation signal, obtained by using the estimated amplitude and phase of the individual frequency component, from the original signal. In this paper, we propose a simple compensation algorithm and analysis the performance through simulations. From the results, it is observed that the amplitude and phase can be estimated with under 5 % and 0.17 % in a somewhat poor receiving situation with 0 dB Signal to Noise Ratio (SNR). Also, we analyze the obtainable performance improvement after compensation by using the measured Loran-C data. From the results, it is observed that we can get about 22 % performance improvement when a moving average with 5 minutes interval is employed.

Ship detection from satellite remote sensing is a crucial application for global monitoring for the purpose of protecting the marine environment and ensuring marine security. It permits to monitor sea traffic including fisheries, and to associate ships with oil discharge. An automatic ship detection approach for RADARSAT Fine Synthetic Aperture Radar (SAR) image is described and assessed using in situ ship validation information collected during field experiments conducted on August 6, 2004. Ship detection algorithms developed here consist of five stages: calibration, land masking, prescreening, point positioning, and discrimination. The fine image was acquired of Ulsan Port, located in southeast Korea, and during the acquisition, wind speeds between 0 m/s and 0.4 m/s were reported. The detection approach is applied to anchoring ships in the anchorage area of the port and its results are compared with validation data based on Vessel Traffic Service (VTS) radar. Our analysis for anchoring ships, above 68 m in length (LOA), indicates a 100% ship detection rate for the RADARSAT single beam mode. It is shown that the ship detection performance of SAR for smaller ships like barge could be higher than the land-based radar. The proposed method is also applied to estimate the ship's dimensions of length and breadth from SAR radar cross section(RCS), but those values were comparatively higher than the actual sizes because of layover and shadow effects of SAR.

The ship's chart system was changed from the use of paper chart to the ENC (Electronic Navigational Chart) using ECDIS (Electronic Chart Display and Information System). The introduction of ENC in ships is necessary for ship automation and for the digitalizing of data and integration of information, but unexpected various problems have occurred and are posing a great threat to safe navigation in the transitional period when the new system has been applied to the sea. In this paper, to assess whether ECDIS contributes to the safety of navigation for its intended purposes as new navigation equipment, a usability test of ECDIS was conducted on masters and crew who have used ECDIS on ocean-going vessels. The result was verified with a paired sample T-test, and it was significantly analyzed with the effectiveness of a simplified task; cost efficiency was decreased since ECDIS was used. By analyzing 'MSC.1/Circ.1503 ECDIS - Guidance for good practice', we found that the effects of the maintenance of ECDIS software, operating anomalies identified within ECDIS, differences between raster chart display system (RCDS) and ECDIS, and matters of identification were compounded by the overlapping information on the safety of ships. The anomalies were also grouped according to their characteristics, and we proposed suitable improvements accordingly. The reason for the reduction in efficiency in the usability test was that the problems with ECDIS were intended to be solved only with the careful use of navigational officers who did not have systematic solutions. To solve these problems, the maintenance of software, the improvement of ECDIS anomalies, the reliable ENC issuance including the global oceans, and S-mode development are a priority.

This study attempts to analyze the effect of level of education on the attitudes toward immigrants or foreign workers. More specifically, we examine whether there is significant difference in the effects of the level of education and global mind on the attitude among three East Asian countries (South Korea, Japan, and Taiwan), controlling other socio-demographic factors in relation to increase in immigrants and foreign workers. Using EASS data, we employs sequential logit model to the general attitudes toward immigrant workers into the weighted sum of transition probability within each educational level. One major finding is that there is clear and significant difference in the relationship between the level of education and the attitudes toward foreign workers among three countries. In general, while Japanese and Taiwanese tend to have more open-minded attitudes toward foreign workers as they have higher level of education, Koreans are opposite case that they are little bit more hostile toward to foreign workers with higher level of education. Especially, there is strong positive effect of education on the attitude in Taiwanese case. Another finding is that while there is strong resistance against increase in migrant population in Korea and Taiwan, Japanese respondents want current level of foreign population to remain in the similar level. Our findings imply that there is no one converging pattern of relationship between the level of education and the positive attitudes toward foreign workers which can be applied to any country. Therefore, this paper suggests that unique political, social, and cultural characteristics of each country should be considered to better understand the effect of education on the attitude toward immigrants and foreign workers. Also, we conclude that systematic comparative-demographic analyses should be utilized to provide more comprehensive picture of how difference in educational level affects the attitude toward immigrants and foreign workers.

CHIME (chemical Th-U-total Pb isochron) geochronology were made for Precambrian rocks from Goseong-Ganseong area, northeastern part of the Gyeonggi massif. Zircon and/or monazite grains from orthogneisses give $1672{\pm}69\;to\;1414{\pm}36Ma$ ages, and monazite grains from paragneisses yield similar ages ranging from $1703{\pm}70\;to\;1395{\pm}97Ma$ suggesting that $1.7{\sim}1.4Ga$ igneous intrusions and coeval metamorphisms were occurred over the area. Together with reported prevailing $1.9{\sim}1.8Ga$ igneous activities and regional metamorphism from the Cyeonggi massif, our age data from Goseong-Ganseong area would be potentially correlated with long-lived $(1.8{\sim}1.3Ga)$ global tectonotermal events in marginal outgrowth of supercontinent Columbia which was finally assembled by collisional orogenies at ${\sim}1.8Ga$. Petrological and geochmical studies, however, should be followed to confirm this tectonic interpretation.

Open economy tightly works with foreign economy. This paper investigates the effect of the shock of foreign bond yield on the credit spreads of domestic corporate bonds in Korea. Foreign bond is referred to as US treasury bond. Credit spreads are defined with the difference between log yields of domestic corporate bonds and log yield of Korea treasury bond. With the data of monthly three-year AA- and BBB- corporate bond yields- ratings, monthly three-year Korean treasury bond yields, monthly US dollar foreign exchange rates, and monthly three-year US Treasury bond yields during the period from October 2000 to September 2014 including global financial crisis period, the paper documents the results as follow. First of all, the yield of Korean treasury and the credit spreads are very sensitive to the increase in the level and the volatility of the yield of the US treasury bond. Changes in the level and the volatility little affect the change of the exchange rate. Second, the change in the level and the volatility negatively affect the level of Korean treasury bond yields but lead to the increase in the level of Korean treasury bond yields at the same time. Third, there exist time lags of the increases of credit spreads by the increase in the level and the volatility. These imply that credit spreads and bond yields are very sensitive to the change in the yields of foreign bonds such as US treasury bond.

Open banking, the global trend of the financial industry, is the driving force behind various innovations in the financial market in the future. The right policy direction and detailed tasks are important for triggering the differentiation and reunion of the financial industry. The purpose of this study is to investigate and analyze the background of open banking, domestic and international trends, and Korea's open banking policy. The policy directions and tasks for successful settlement and activation of open banking system are carefully suggested. Open banking is a policy to allow third party provider(TPP) access to bank accounts and open payment functions under the explicit consent of the customer. The opening of the open banking era is expected to begin competition and cooperation between banks and fintech companies in earnest, thus enhancing the competitiveness of the financial industry and contributing to the utility of financial consumers. To this end, policymakers should make every effort to advance open-ended financial settlement infrastructure, open banking legal grounds, and minimize side effects such as customer data leakage and poor financial system stability. Banks and fintech companies will need to focus on scattered customer financial information on a single platform and develop it into a convergence and discrimination of true financial services.

Social enterprises can be identified roughly as social purpose-oriented business ventures. They often fill the gaps left by governmental and commercial ventures in providing for certain vulnerable sectors of society. Though social enterprises often adopt market mechanisms in their organizational structures, their emphasis on particular social outcomes means that they intentionally pursue double/triple-bottom lines, thus distinguishing them from many traditional for-profit businesses. Among the Korean laborers, women have been hardest hit by the global economic crisis. As the movements have substantially been taken to strengthen women's economic activities in the recent years, many policies are formulated with these trends, connecting women's employment with social enterprises. This study focused on analyzing social enterprises to be friendly and to provide decent work to women. Data were collected from 491 social enterprises and 830 workers. The main results are as follows. First, the women's employment in social enterprises has accounted for a relatively high rate and the women's wage also is similar to men's one. Second, as for work conditions and types, most women have preferred irregular and non-managerial work. Thus, social enterprises have showed a positive response for the women's job opportunities, while social enterprises have had a negative one for enhancing the women's status at the labor market. In conclusion, social enterprises should institutionalize how to provide more stable working condition to women and to improve their's capacity.
