The study examined how changes in time invested in private tutoring and academic achievement influenced each other through a multivariate latent growth model by using the data from the first to the third year presented in the KYPS. This study identifies not only how changes in the private tutoring experience exerted a direct influence on changes in academic achievement, but also measures what kind of changes in private tutoring and academic achievement had emerged over time. The detailed study results are as follows. First, the analysis of time invested in private tutoring showed that the higher the grades, the greater were the amount of time invested in private tutoring in the case of Korean language study. On the other hand, the results showed that in the case of English and mathematics, the higher the grades, the lesser was the amount of time invested in private tutoring. Second, private tutoring and academic achievement were all in a linear relationship. Third, it was shown that the time invested in private tutoring and academic achievement exerted a negative influence on each other according to the passage of time.

As a current popular technology, the blockchain has a serious issue: the private key cannot be retrieved due to force majeure. Since the outcome of the blockchain-based Bitcoin, there have been many occurrences of the users who lost or forgot their private keys and could not retrieve their token wallets, and it may cause the permanent loss of their corresponding blockchain accounts, resulting in irreparable losses for the users. We propose a recoverable private key scheme for consortium blockchain based on the verifiable secret sharing which can enable the user's private key in the consortium blockchain to be securely recovered through a verifiable secret sharing method. In our secret sharing scheme, users use the biometric keys to encrypt shares, and the preset committer peers in the consortium blockchain act as the participants to store the users' private key shares. Due to the particularity of the biometric key, only the user can complete the correct secret recovery. Our comparisons with the existing mnemonic systems or the multi-signature schemes have shown that our scheme can allow users to recover their private keys without storing the passwords accurately. Hence, our scheme can improve the account security and recoverability of the data-sharing systems across physical and virtual platforms that use blockchain technology.

This study attempted to investigate household's private educational expenditure that aggravates a burden on households by using the data from the 2014 Private Education Survey published by Statistics Korea. The effects of purposes of private education and participation in an after school program that is pushed by the government on household's private educational expenditure were analyzed. The major findings were as follows. First, the major purposes of private education lean toward preparing to enroll in school and relieving parents'uneasiness rather than prior learning Second, according to the purposes of private education, the differences of the private educational expenditure were verified. Households spend the highest level of private educational expenditure for the purpose of preparing to enroll in school contrary to the lowest level, which was for the purpose of compensatory learning. Third, participation in an after school program that is regarded as a method of moderating households' private education burden, had a positive effect on reducing private educational expenditure. Forth, private educational expenditure was influenced by the purposes of private education and participation in an after school program. In 2014, the Korean government enforced a law that prohibits schools'education in advance (prior learning) and regulates private educational institutes'advertisement about prior learning. Regarding this regulation, this study aimed to investigate the purposes and expenditure of private education to provide an empirical reference to determine the improvement of related policies.

The purpose of this study was to determine the effect of expenditure on private education and stress caused by private education on the parental efficacy of mothers of junior and senior high school students. The subjects were 300 mothers of students who were enrolled in the junior and senior high school in Seoul and its suburbs. The results were as follows: First, the level of stress from private education was found to be higher than the degree of parental efficacy. Second, a hierarchical regression analysis was performed by using expenditure on private education and stress caused by private education as independent variables and the socio-demographic characteristics of mothers as control variables in order to identify their effect on the parental efficacy of mothers of junior and senior high school students. The results show that stress from private education and monthly income were significantly related to parental efficacy. That is, the lower the level of stress from private education and the higher the monthly income, the higher was the degree of parental efficacy. These findings suggest that expenditure on private education seems to be determined by the household income level; thus, income may affect psychological stress and parental efficacy of mothers with respect to the process of providing private education.

Background: As coverage of public insurance is not sufficient to cover diagnosis or treatment of cancer, having private health insurance is important to prepare for unexpected expenses of cancer. The purpose of this study was to assess factors associated with having private cancer insurance, considering gender among the socio-demographic factors and health behavior. Materials and Methods: We used data from the 2011 Korea Health Panel, which included 10,871 participants aged 20 years and older. Socio-demographics, health behavior, and perceived cancer risk were the independent variables and having private cancer insurance was the dependent variable. Multivariable logistic regression analysis was used to identify factors associated with having private cancer insurance. Results: The variables relating to middle age, higher education, higher household income, married men, and the perceived cancer risk groups of 1-10% and 11-30% were significantly associated with having private cancer insurance. Additionally, females who had private non-cancer health insurance were positively associated with the dependent variables (OR=1.36; 95% CI=1.17-1.57). Education, smoking status, exercise, and perceived cancer risk possibility were significantly associated with having private cancer insurance only among women. The men lowered the overall percentages of those having private cancer insurance (OR=0.53, 95% CI=0.45-0.63). Conclusions: We found that there were significant differences between men and women who had private cancer insurance. Women with private cancer insurance are more likely to follow precautionary health behavior than men. This could be interpreted as resulting from masculine ideologies. It is important to make males recognize the seriousness of the cancer risk. In general, household income was highly associated with private cancer insurance. These results reveal an inequity among the buyers of private cancer insurance in terms of economic status level, education level, and health condition.

The Port Development has been achieved by the Government because it needs large scale of funds. However, since 1994, the Govenment has been implemeting private investments for constructing and operating the ports and so on. Although the Government had high expectation that it could expedite the expansion of the port facilities, there were many problems in view of construction, management, financial and social environment. This study figure out that most of the important reasons are the uncertainty of risk allocation between private investors and the Government, using with Analytic Hierarchy Process. It is expected that the results of this study will encourage more private investors to participate in port private investments in the future.

Objectives : This study was conducted to verify the influence organizational health has on customer orientation by hospital ownership. Methods : This survey was conducted on a public hospital, private hospital, and religious hospital, respectively, during March 2014 and a total of 210 questionnaires were used in the analysis. ANOVA and regression analysis were used to analyze the collected data. Results : The management environment factor of organizational health was statistically significant in the public hospital compared to the private hospital. The reliability factor of customer organization was statistically significant in the public hospital and religious hospital respectively compared to the private hospital. For reactivity, the religious hospital was statistically significant compared to private hospital. A positive influence was shown in the vitality factor at the public hospital, and community orientation at the private hospital, while both community orientation and career showed effects at the religious hospital. ICU had a negative influence on customer orientation at the private hospital. Conclusions : The reason vitality had a relatively more important effect on customer orientation in the public hospital was due that age group of 20~29 was the dominant socio-demographic factor. Furthermore, the influence of community orientation on customer orientation in the private hospital and religious hospital may be related to the nurses' career.

According to the current record of Private Security in Korea, more than 110,231 private security guards and around 2,213 security guard associations are engaged in the private security industries. However, there is no a professional license for the private security. In order to be provided a high quality service from private security industries, the security guard should be required his/her professional qualification which can be upgraded by establishing a professional license system. For introducing the license system the government and security guard associations need to support the suitable training program including curriculum and method, and all associations related to the private security have to require people involved in any kinds of private security matters to complete obligatorily some educational training programs. And also, to complete a college should be the minimum requirement.

The paper aims to investigate the impact of foreign direct investment (FDI) on private investment with a sample having 49 developing countries in Asia (17 countries) and Africa (32 countries) during the period of 1990-2017. Unlike previous studies, we split the data into three groups for further analysis, including the Asian, African and the full-panel samples. The results confirm a crowding-in effect which shows that foreign direct investment promotes private investment on all three research samples. Besides, the lagged private investment has a positive and significant effect on itself in the next period which reflects the inertia in the trend of private investment in recipient countries. In the full-panel sample, there are some macro factors such as GDP per capita, trade openness, and electricity that also have a positive and statistically significant impact on private investment. Besides, when more deeply estimate with smaller samples, we find that trade openness and labour force have a positive and significant in Africa, on the other hand, not in Asia. However, the domestic credit variable has a negative and significant effect on private investment only in Asian developing countries. Furthermore, there is only a positive and significant impact of the electricity variable on private investment in Asia.
