This study examines the relationship between voluntary information disclosure and the effective tax rate using Investor Relation (IR) as the proxy for the level of the firm's voluntary information disclosure, and effective corporate tax rate as the proxy for the level of tax avoidance. This study considers sample data from 1,396 firms listed on the Korea Composite Stock Price Index (KOSPI) from 2011-2014. The results of this study are as follows: Investor Relation (IR) had a positive correlation with effective corporate tax rate. This result got on with the result of additional analysis using extra measurement of effective corporate tax rate. According to these results, we expect that firms featuring greater voluntary information disclosure report enhanced business performance. This study contributes understanding how Investor Relation (IR) affects tax avoidance. We hope that this study can promote the development of capital markets and provide good news to investors for firms that have greater information disclosure.
With advances in topic detection and tracking(TDT), automatic trend analysis from a collection of time-stamped documents, like patents, news papers, and blog pages, is a challenging research problem. Past research in this area has mainly focused on showing a trend line over time of a given concept by measuring the strength of trend-associated term frequency information. for detection of emerging trends, either a simple criterion such as frequency change was used, or an overall comparison was made against a training data. We note that in order to show most salient trends detected among many possibilities, it is critical to devise a ranking function. To this end, we define four properties(change, persistency, stability and volume) of trend lines drawn from frequency information, to quantify various aspects of trends, and propose a method by which trend lines can be ranked. The properties are examined individually and in combination in a series of experiments for their validity using the ranking algorithm. The results show that a judicious combination of the four properties is a better indicator for salient trends than any single criterion used in the past for ranking or detecting emerging trends.
Most of the North Korean defectors are the socially disadvantaged, and formed the lowest class in South Korean society. Their main objectives are to achieve economic wealth. In this process, North Korean defectors have often committed the crime or have been criminal victims. The purpose of this study was to propose the effective preventive measures after analyzing the actual situation of North Korean defectors in criminal behaviors and criminal damages. This research has studied of the literature on the criminal behavior and the criminal damage by North Korean defectors, utilized the relevant statistical data, cited the news for the relevant cases, and proposed the effective preventive measures of criminal behaviors and criminal damages of North Korean defectors by doing in-depth interviews with personal protection officer First, in order to prevent criminal activity by North Korean defectors, we should uplift the identity as the members of Korean society, systemize the initial adapt education, enlarge the employment protection and the resettlement helper system, manage North Korean defectors according to adaptive type, develop the network, establish the management department for the defectors, strengthen the training of prison inmates, and strengthen the management of unprotected people. Next, in order to prevent the criminal damages of North Korean refugees, we should manage vulnerable North Korean defectors effectively, maintain the liaison between the personal protection officer and North Korean defector, arrange the personal safety measures in advance when traveling abroad, enhance the legal education for usual living in Korean society, and perform the re-education for the female socialization.
For the past 20 years, expert groups and citizens in Korea have debated on the usefulness of personalized medicine. These debates were mainly focussed on the possibility of the promise - people mainly discussed whether it was a probable future or if it was just a hype. Following Hedgecoe and Tutton(2002) who argue that it is only a 'rhetorial device', we will analyze about 9,000 news media coverages that deal with personalized medicine. With these data, we will show that the same terminology of personalized medicine have been used very differently according to the time and people who use it. Our research will show that this term has both diachronic heterogeneity and synchronic equivocality. This has happened because of the innate lack that exists in our symbolic system. Policy and governance regarding new technology is important because they provide quilting point to those slippery term/signifiant. Also we would like to carefully suggest that we might be able to call this phenomena as signifiant-politics.
In this study, the case of OO corporation was based on to examine the business performance and method of OO corporation and the competitive advantage and success factors were considered. For the progress of this study, references and advanced researches related to entrepreneurship, authentic leadership, and organizational effectiveness, which were suggested as the core competence of non-profit organizations, were examined and textual information was secured through the homepage of the targeted organization and news articles. Lastly, data needed for the research was collected through an interview with the Chief Executive Officer (CEO) of the organization. Through the process and analysis, the following findings were identified. First, the entrepreneurship of the CEO can apply as a core competence for the operation of the non-profit organization. Second, the proposition was derived that the roles of the CEO and leadership can apply as a key competence in the operation of the non-profit organization. This study implies that the many theories and strategies which were only targeted on companies can also be applied for the research of non-profit organizations. Moreover, concerning modern corporate management, strategic approach of non-profit organization characteristics like a sense of mission, fairness, and ethics can promote the creation of sustainable competitive advantage.
Recently, there is a growing body of literature that suggests that information inefficiency is one of the causes of the asymmetric volatility. If this explanation for the asymmetric volatility is appropriate, then innovations, such as the introduction of futures, may be expected to impact the asymmetric volatility of stock market. As transaction costs and margin requirements in the futures market are lower than those in the spot market, new information is transmitted to futures prices more quickly and affects spot prices through arbitrage trading with spots. Also, the merit of the futures market may attract noise traders away from the spot market to the futures market. This study examines the impact of futures on the asymmetry of stock market volatility. If the asymmetric volatility is significant lower post-futures and exist in the futures market, it has validity that the asymmetric volatility is caused by information inefficiency in the spot market. The data examined are daily logarithmic returns on KOSPI 200 stock price index from January 4, 1993 to December 26, 2000. To examine the existence of the asymmetric volatility in the futures market, logarithmic returns on KOSPI 200 futures are used from May 4, 1996 to December 26, 2000. We used a conditional mode of TGARCH(threshold GARCH) of Glosten, Jagannathan and Runkel(1993). Pre-futures the spot market exhibits significant asymmetric responses of volatility to news and post-futures asymmetries are significantly lower, irrespective of bear market and bull market. The results suggest that the introduction of stock index futures has an effect on the asymmetric volatility of the spot market and are inconsistent with leverage being the sole explanation of asymmetry. However, it is found that the volatility of futures is not so asymmetric as expected.

Objectives: This study was conducted to examine the preferences and needs of typical Korean females adults for food and nutrition information provided by the mass media. Methods: A total of 343 females (77 in their 20s, 85 in their 30s, 88 in their 40s and 93 in their 50s) residing in the Seoul/Gyeonggido area was surveyed on general characteristics, main sources of food and nutrition information and needs for sources and contents of nutrition information. Results: The survey showed that typical Korean females obtained knowledge of food and nutrition mainly through the Internet (30.4%) and broadcasting (29.0%). Typical Korean females were interested in 'dietary management for weight control' (21.9%), 'the prevention and treatment of disease' (20.0%), 'food safety' (16.8%), 'proper dietary habits' (14.6%), 'cookery' (11.8%), 'functional foods' (9.6%), 'restaurant details' (3.5%) and 'life-cycle-specific dietary guideline' (1.6%). Needs for food and nutrition program forms on TV were 'educational programs' (34.3%), 'documentaries' (20.8), 'expert lecture-style' (13.0%), 'entertainment programs' (11.9%), 'expert conversation' (11.4%), 'news-style' (4.6%) and 'public campaign advertisements' (4.0%). On the Internet, 38.6% of the respondents preferred to get information provided by food and nutrition-related institutions (38.6%) while 26.1% preferred webtoons for nutritional information. The favored forms in mobile applications were 'monitoring their diets' (29.5%), 'data-based texts information' (21.4%), 'experts feedback' (20.6%), 'communities' (15.1%) and 'games' (13.1%). The rates of the preference to obtain information from experts such as nutritionists and dietitians and doctorsor dietitian turned reporters increased markedly with older ages. Conclusions: Since the mass media is a main source of food and nutrition information for the general public, the effectiveness and accuracy of the information provided should be enhanced by taking the needs of the public into account. The quality of information should be improved by involving more nutrition experts.
This paper describes the incidence and some epidemiological features of drowning accident out of a series of our study on the epidemiology of various accidents in Korea. By the daily press it is apparent from the frequent reporting of swimming accidents that the incidence would be high. In the rural areas, there are, at present, about 1,250 artificial lakes and farm ponds to be utlized for rice production. The reservoirs, irrigation ditches and riversides are also used for recreation. In most places facilities for aquatic activities is meager, and safety measures for the prevention of drowning is not sufficiently enforced. In the survey crude data on drownings were collected from the concerned governmental statistic books for the period 1955 to 1967 which were compiled not in a uniform way. Drownings were classfied into two categories, one is accidental drowning, E 929 and the other is due to cataclysm, E 934, according to the WHO international classification of diseases. Epidemiological variables in relation to drowning accident were obtained through qualitative analysis of informations from the popular news papers. The following summary may be drawn; 1. The average number of deaths due to accidental drowning totaled 1,088 annually and the mortality rate per 100,000 population was 3.4, The 42.0% of all drownings were rescued and the remaining were not saved. 2. The sex ratio (M/F) of the victims for all ages was 5 to 1, which had a wide range of difference among the age groups. The young ages less than 20 years occupied 68.0% of all deaths. 3. The percentage distribution of the causes of accidents revealed 31.9% for careless swimming, 45.5% for unskilled, 10.6% for swimmer's cramp and 6.0% for drunked. The distribution of places where accidents occurred showed 88.0% for rivers, water reservoirs, irrigation ditches and 12.0% for regular swimming pools. The seasonal distribution of cases indicated 85.0% of the total were seen during the summer months, June-August, and 50.0% of them occurred on Sundays, 4. The average annual deaths due to cataclysm were 402 and mortality rate per 100,000 population was 1.6, but the number of victims due to cataclysm varied greatly each year. 5. The accident cases due to cataclysm were classified into 60.0% for injuries, 40.0% for deaths. The 26.8% of all deaths were missing cases. 6. The deaths due to either accidental drowning or cataclysm totaled 1,490, and the death rate per 100,000 for the whole country was 5.0.

The purpose of this study is to investigate the directions of information and communication technology(ICT) education in K-12 based on the analysis of ICT accessibility and utilization levels of Korean students. To this end, we analyzed the trends of Korea and OECD countries by survey period, focusing on the OECD PISA 'ICT familiarity survey' conducted in 2009, 2012 and 2015. The surveyed subjects were 15 year-old students and the analysis method was calculated based on the sampling weights. The results of the analysis of Korean students are as follows: First, ICT accessibility at home increased from 2009 to 2015, but was consistently lower than the OECD average. Second, the overall Internet usage time was lower than the OECD average. The Internet usage time on weekdays increased from 2012 to 2015, but on weekends decreased. Third, the ICT accessibility in schools decreased from 2009 to 2012, and increased in 2015, but was lower than the OECD average in 2015. Fourth, the student age ratio of first time computer usage increased from 2012 to 2015 and the average age for computer usage began before age 6, but was below the OECD average. Lastly, student use of digital devices for items such as Internet searches for entertainment and SNS activity has increased from 2012 to 2015, but the level of everyday use such as e-mail, online chat, program downloading, and reading Internet news has decreased. Based on these results, this study suggested policy plans for the improvement of ICT education for elementary and secondary school students in Korea.
