본 연구는 우리나라의 민간의료보험 가입자의 인구·사회·경제학적 특성과 가입자와 미가입자간의 질병 유형, 예방 및 건강행태, 의료이용 양상 등을 비교하였다. 그리고 민간보험 가입의 영향을 파악하여 향후 국민건강보험 및 민간의료보험 관련제도의 바람직한 발전방향을 제시하기 위한 기초자료 활용에 그 목적이 있다. 연구의 결과는 민간의료보험 가입 요인은 인구?사회?경제적 요인이 유의하게 나타났으며, 국민건강 영양조사에서 이루어진 인플루엔자 예방접종율과 건강보험 건강검진은 민간의료보험 가입자에게서 더 낮았고, 지난 2년간 본인부담 건강검진비율과 지난 2년간 암검진비율은 민간의료보험 가입자의 검진율이 더 높았다. 그리고 건강행위 평균을 민간의료보험 가입여부별로 보면, 격렬한 신체활동을 실천하는 비율은 민간의료보험 가입자가 더 높았고, 평균 수면시간, 1주일간 격렬한 신체활동을 하는 일수, 1주일간 중등도 신체활동을 하는 일수, 1주일간 유연성 운동일수 및 1주일간 근력운동일수에서도 민간의료보험 가입자가 미가입자 보다 많았다. 걷기를 실천하는 비율과 1주일간 걷기일수는 민간의료보험 가입자가 미가입자보다 적었다. 의료이용에 민간의료보험이 어떤 영향을 미치고 있는가를 살펴본 결과에서는 외래이용이 있는 경우와 입원이용횟수에서 민간의료보험가입자가 미가입자보다 외래를 이용할 확률이 높았고, 더 많은 횟수의 입원이 관련 요인으로 나타났다. This study firstly examined the socioeconomic and health factors associated with infiltration of private health insurance. Secondly, we compared health behavior, outpatient and inpatient use of private health insured with uninsured. The method of this study is that secondary analysis of the 2008 Korea National Health and Nutrition Survey was conducted for 7178 respondents aged 19 over. We use the logistic regression and t-test for data analysis. The first dependent variable was dichotomy which is divided to private health insured or uninsured and the second dependent variable was the presence and frequency of outpatient and inpatient use. The descriptive variables was gender, age, marital status, income, education, occupation, type of national health insurance, residential area, self confidence of health, prevalence rate of common disease, activity limitation, drinking and smoking status. The result of the major findings are as follows. First, 59 under aged person, married person, people in the higher brackets of income, national employee insured were more likely to infiltrate private health insurance. The poor self confidence of health, activity limitation, person with hypertension or allergic rhinitis and smoker were negatively related in infiltrating private health insurance. Second, private health insured did more preventive behavior such as self-paid health examination, cancer screening, regular exercise than uninsured. Third, private health insured was positively related with the presence of outpatient use and frequency of inpatient use.

The increase of the number of smartphone applications has enforced the importance of new user interface emergence and has raised the interest of research in the convergence of multiple sensors. In this paper, we propose a method for the convergence of acceleration, magnetic and gyro sensors to recognize the gesture from motion of user smartphone. The proposed method first obtain the 3D orientation of smartphone and recognize the gesture of hand motion by using HMM(Hidden Markov Model). The proposed method for the representation for 3D orientation of smartphone in spherical coordinate was used for quantization of smartphone orientation to be more sensitive in rotation axis. The experimental result shows that the success rate of our method is 93%.

The purpose of this study is to observe the capital market reaction concerning designation as an unfaithful disclosure company and imposition of penalty points. For this purpose, two methodologies are used in the study. The first methodology is the event study method which analyzes the stock market return before and after unfaithful disclosure designation due to reasons such as disclosure failure, disclosure overturn and disclosure change. The second methodology is the regression analysis method where the dependent variable is set as the daily stock return of the unfaithful disclosure company and the explanatory variable is set as the unfaithful disclosure penalty point. Information disclosure to the capital market performs the function of enabling efficient allocation of resources by alleviating the information asymmetry problem that exists between the internal and external users of companies. If the reliability and accuracy of the information disclosure which performs these functions are not secured, the market participants will have doubts on the reliability of the information provided by the companies, and there will be difficulty in assessing the objective value of the companies. Being designated as an unfaithful disclosure company means there is an error in the speed, accuracy and reliability of the information disclosure of the company, and it can be said that the gravity of the violation is heavier when the penalty is higher. If market participants interpret unfaithful disclosure designation and imposition of a penalty as increased uncertainty of information disclosure and a decline in reliability, the resulting negative perception will be reflected in the stock prices. Therefore, if the designation of unfaithful disclosure has an additional information effect in the capital market, the corresponding company is expected to have a negative stock price reaction on the day of unfaithful disclosure designation. This expectation has been validated by Sohn(2001) and Choi et al.(2013). However, since there is a chance that the results of previous studies such as these are due to many other factors of unfaithful disclosure of a corporation, it cannot be concluded with certainty that the cause of the negative stock price reaction is only due to unfaithful disclosure. Therefore, in addition to the case studies of previous studies, this study conducts regression analysis on the profit rate of the date of unfaithful disclosure company designation and penalty points for unfaithful disclosure, to verify aspects previous studies failed to verify due to inadequate material on penalty points. The analysis result shows a drop in the stock market return from the day of the designation of unfaithful disclosure, and a statistically significant negative cumulative return. This result signifies that stock market participants perceive designation of unfaithful disclosure as a negative event that impacts stock prices. Meanwhile, though the negative response was expected to increase proportionally with the imposed penalty points during the quarter of penalty imposition, the penalty points and negative reaction of the capital market were found to be unrelated. On the other hand, the negative response of the capital market was found to increase according to the level of penalty accumulation through past designation of unfaithful disclosure. This study is differentiated from previous studies as it directly observes the effect of penalties through a short-term stock price reaction based on the date of unfaithful disclosure designation. In addition, the study presents an intuitive result that the expense of a firm may increase due to the designation of unfaithful disclosure. Furthermore, the result of this study that unfaithful disclosure penalties accumulated from the past is related to the capital market reaction on the day of unfaithful disclosure designation is expected to provide significant implications to information users such as executives,

Due to political problems in Korea and China in 2017 due to the political problem, the Korean tourism industry is experiencing a cold weather due to the collapse of the national image and the Han Hallyeong. Accordingly, it seems to be a time to make a positive and balanced approach to the unbalanced tourism flow between China and Korea The results of this study are as follows: First, the image of Korean tourists perceived by Chinese tourists is 'good', 'clean', 'expensive', 'good living and natural environment'. Second, in the type of reminders, the human and social image was most derived. Third, in the type-by-type evaluation, entertainment image and natural environmental image were positive. Finally, the evaluation of Korean tourism image according to sex and number of visits was generally positive, negative, and neutral. finally, it is considered that negative images should be prevented by emphasizing other positive image in order to alleviate the image of the country that has fallen due to political reasons between the two countries.

본 연구에서는 2014년부터 시행되고 있는 특별전형이 본래의 목적을 달성하고 있는지를 살펴보기 위하여 2014 ~ 2017년까지 해사에 지원하고 입교한 사관생도 510명을 대상으로 입학전형(특별전형과 일반전형)에 따 른 입교 및 자퇴율, 성취점, 그리고 성취점 구성요인에 어떤 차이가 있는지와 입학서열과 학과서열 간 상관이 없 다는 암묵적 통념이 옳은지를 살펴보았다. 전형집단별 입학률은 특별전형집단이 일반전형집단에 비하여 높았으 나, 입교 후 자퇴율에서는 두 집단 간 차이를 확인하지 못하였다. 입학시험 성적을 기준으로 전형집단 간 학습수 준에 차이가 있는지를 비교한 결과에서는 두 집단 간 유의한 차이가 없었던 반면, 입교 후 각 학기별 성취점을 비교한 결과에서는 특별전형집단이 일반전형집단에 비해 우수한 것으로 나타났으며, 전형별 10분위 누적 그래 프에서도 학년이 올라 갈수록 상위 1/2에 속하는 비율이 더욱 높은 것을 발견하였다. 성취점 구성요인에서는 학 과요인과 훈육요인이 특별전형집단에서 높게 나타났으나, 체육요인은 두 집단 간에 차이가 없는 것으로 나타났 다. 전형에 관계없이 입학시험성적과 학과성적과의 상관분석에서는 입학시험 성적과 학과성적은 통계적 상관이 없는 것으로 나타났으나 1학년 1학기 성적은 이후 학과성적 및 누적서열에 보통이상의 상관이 있는 것으로 나타 났다. 향후 특별전형 집단과 일반전형 집단의 성취도 차이는 어디에서 기인하는지와 현재의 전형집단별 차이가 졸업은 물론 군 생활을 통해서도 다른 차이를 보이는지에 관한 종단연구 그리고 입교 시 상위권 집단 및 1학년 1학기 학과성취도가 낮은 집단에 대한 동기부여 방안 등 다양한 연구가 병행 추진되어야 한다.
