In the early 2012, European Union proposed new legal framework, including the right to be forgotten, for the protection of personal data. The new Proposal articulates kind of sweeping new privacy right and there has been debates on its potential threat to free speech in the digital age. While the situation is similar in Korea, I want to introduce the right to be forgotten in the Proposal. Then, I will analyze current legal system in Korea regarding the new privacy right and suggest some guidelines in searching direction for the coming legislation with respect to the right to be forgotten. The right to be forgotten should not have been promulgated without considering fully its effect on the free speech, especially in the society where the voice toward direct democracy or movement toward participation of the citizen, mainly through cyber space or Social Network Services, has risen much higher in Korea. Especially, the new right seems not to cover the control of data subject on a third party where the third party expressing his opinion by posting himself other's personal data on his blog or others.

Since the resolution of the 2-D hole-to-hole seismic traveltime tomography is affected by the limited ray transmission angle, various methods were used to improve the resolution. Linear traveltime interpolation(LTI) ray tracing method was chosen for forward-modeling method. Inversion results using the LTI method were compared with those using the other ray tracing methods. As an inversion algorithm, SIRT method was used. In the iterative non-linear inversion method, the cost of ray tracing is quite expensive. To reduce the cost, each raypath was stored and the inversion was performed from this information. Using the proposed method, fast convergence was achieved. Inversion results are likely to be affected by the initial velocity guess, especially when the ray transmission angle was limited. To provide a good initial guess for the inversion, generalized regression neural network(GRNN) method was used. When the transmitted raypath angle is not limited or the geological model is very complex, the inversion results are not affected by initial velocity model very much. Since the raypath angles, however, are limited in most geophysical tomographic problems, the enhancement of resolution in tomography can be achieved by providing a proper initial velocity model by another inversion algorithm such as GRNN.

The purpose was to describe the state of healthcare-associated infection(HAI) control. Data were collected from 134 hospitals. The questionnaire developed by Kang[8] were modified. The mean of hospital beds was 556.4, 26.9% of hospitals were less than 300 beds. 99.3% of hospitals had infection control committee(ICC). ICC met 3.4 times a year. 54.5% of hospitals had one infection control practitioner(ICP). 95.5% of ICPs were nurse, 48.7% of ICPs had more than master's degree. Hospital experience of ICPs was 13.5 years. ICP experience was 3.2 years. 30.8% of ICPs worked for less than 1 year. All hospitals investigated HAI, 75.4% performed improvement activities. There are significant differences in existence of ICD, negative pressure room, computer program, numbers of ICPs according to hospital size. Manpower, organization, and facilities lacked in less than 300 beds. This conclusions will give baseline data to establish infection control system, manpower and practice in small-medium hospitals.

This paper studies the partial credibility application method by assuming the empirical prior or noninformative prior informations in auto insurnace business where intensive rating segmentation is expanded because of premium competition. Expanding of rating factor segmetation brings the increase of pricing cells, as a result, the number of cells for partial credibility application will increase correspondingly. This study is trying to suggest more accurate estimation method by considering the Bayesian framework. By using empirically well-known or noninformative information, inducing the proper posterior distribution and applying the Bayes estimate which is minimizing the error loss into the credibility method, we will show the advantage of Bayesian inference by comparison with current approaches. The comparison is implemented with square root rule which is a widely accepted method in insurance business. The convergence level towarding to the true risk will be compared among various approaches. This study introduces the alternative way of redcuing the error to the auto insurance business fields in need of various methods because of more segmentations.

This study analyzed the status and trend of gender wage gap among listed companies in KOPSI market over the 2000-2017 period. The main results of the study are as follows. First, the gender employment gap index for KOSPI listed companies stood at 39.81 in 2017, with 40 women per 100 men being employed. Although the absolute value of the proportion of female employment remains low, it has not only been higher than 33.74 in 2000 but has also increased steadily in recent years. In terms of the number of years of service, the average number of male employees in 2017 was 9.9 years, compared with 6.9 years for female employees, and the gender tenure gap decreased over the past few years. Finally, The gender wage gap index increased from 60.57 in 2000 to 67.87 in 2017. In addition, there are slight variations in the size of the company or industry, but consistent results have shown that the gender wage gap decreases in recent years. The findings suggest that our society is developing in a way that reduces the gender employment gap and the gender wage gap.

The present study was designed to investigate the chemopreventive effects of supercritical heat radish extracts with anti-constipation acitivity in loperamide-treated rats, on 1,2-dimethylhydrazine(DMH)-induced aberrant crypt foci(ACF) in rat colonic mucosa. Supercritical heat radish extracts was administered in the drinking water(3.2 mg/ml) during the initiation (for 12 weeks) or postinitiation phase(for 9 weeks) of DMH-induced carcicogenesis. Supercritical heat radish extracts coupled with DMH for 12 weeks decreased significantly total number of aberrant crypts(pre-neoplastic lesions) and the number of ACF to 35% and 30%, respectively. The number of ACF with more than four aberrant crypts (crypt multiplicity) was significantly reduced in the colon of rats receiving Supercritical heat radish extracts for 12 weeks. In the group receiving Supercritical heat radish extracts after post-initiation for 9 weeks, only the number of ACF with ${\geq}4$ abberant crypts significantly decreased. Supercritical heat radish extracts, given alone for 12 weeks, did not induced the development of ACF. These results indicate that Supercritical heat radish extracts possess chemopreventive effects on chemically induced rat colon carcinogenesis.

Recently, most online firms are trying to provide personalized services based on customer's data. However, customers are reluctant to give their information to online firm because of concerns about data breach. Online firms are seeking to increase their trust by ensuring the protection of personal information for customers through privacy seal (e.g. e-privacy) or data breach insurance. This research examines the effects of privacy assurance(i.e. privacy seal, data breach insurance) on consumer behavior in online environment. An experiment based on the hypothetical scenario was conducted using a between-subjects 2 (type of privacy assurance) + 1 (control) design. We found that both privacy seal and data breach insurance increased perceived privacy trust. In addition, privacy seal has a positive effect on the intention to provide personal information through perceived privacy trust. Finally, in the case of the group with a high (low) disposition to trust, higher perceived privacy trust is formed through privacy seal (data breach insurance). Theoretical and practical implications are discussed.

The purpose of this study is to investigate the burden of caring for the care-givers of the elderly in Korea by using an integrated literature review method. A total of 23 studies were analyzed using a search database. When care-givers had higher sense of filial and guilt or more than two diseases, they showed high level of feeling of burden. Also, they had high level of feeling of physical burden by their oldness, service period (especially at the period of 1-3 years). In the feeling of economic burden, they had high level of feeling of burden by their oldness, or elderly's disease periods. The feeling of burden by psychological condition was found in elderly in aged and the beginning of admission of nursing home. The feeling of burden by environment situation was found when the functional status of the elderly was bad. Therefore, we need to concern care-givers's feeling of burden with elderly people in the nursing home. In the future, I believe that the findings of this study will be helpful for development of the intervention program for alleviate burden for the care-giver.

The purpose of this study was to examine to identify factors affecting wellness of workers. This study collected questionnaire data from 172 workers from two large workplaces more than 1,000 workers are located in G city. Data were analyzed using descriptive statistics, Pearson correlation coefficient and Hierarchical regression with IBM SPSS statistics 20.0 program. Wellness of worker was correlated with exercise self-efficacy(r=.23, p<.05), autonomous motivation(r=.38, p<.001), exercise behavior(r=.61, p<.001). Hierarchical regression analysis showed that exercise self-efficacy(${\beta}=.34$, p<.001), exercise behavior(${\beta}=.30$, p<.001), subjective health status(${\beta}=-.23$, p<.001), subjective economic status(${\beta}=-.13$, p=.016) explained 57.3%(F=39.29, p<.001) of wellness of workers. Based on the finding, there is a need to develop an intervention program that consider exercise self-efficacy, exercise behavior, subjective health status and subjective economic status.
