Objectives: This study examined associations among social capital indicators (social participation and generalized trust) at the individual level and alcohol use, which was quantified using Alcohol Use Disorders Identification Test (AUDIT) scores. Methods: In total, there were 8800 participants in community health interviews, including 220 adults sampled systematically from a resident registration database of each of 40 sub-municipal administrative units of local (city or county) governments. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated using polychotomous logistic regression. Results: The aORs for abstainers versus people with AUDIT scores of 0-7, based on 3 questions on generalized trust, in comparison to those with no positive responses, were 1.15 (95% CI, 0.99 to 1.34) for 1 positive response, 1.16 (95% CI, 0.98 to 1.37) for 2 positive responses; and 1.39 (95% CI, 1.20 to 1.61) for 3 positive responses. The aORs for abstainers versus people with AUDIT scores of 0-7, in comparison to participation in no organizations, were 0.61 (95% CI, 0.54 to 0.69) for participation only in informal organizations; 2.16 (95% CI, 1.57 to 2.99) for participation only in religious organizations; 2.41 (95% CI, 1.10 to 5.29) for participation only in volunteer organizations; and 0.65 (95% CI, 0.57 to 0.74) for participation in formal organizations. Participants in formal social organizations, regardless of their participation in informal organizations, were more likely to have AUDIT scores of 8-15 (aOR, 1.29; 95% CI, 1.04 to 1.60) or ≥16 (aOR, 1.65; 95% CI, 1.22 to 2.23) than to have scores of 0-7. Conclusions: Our findings may have implications for health policy to reduce alcohol problems.

Background: This study uses the relevance index to understand the condition of regional medical service use for cardiovascular surgery and to identify the medical service use imbalance between regions. Methods: This study calculated the relevance index of 16 metropolitan cities and provinces using resident registration address data from the Ministry of Government Administration and Home Affairs and the 2010-2014 health insurance, medical care assistance, and medical benefits claims data from the Health Insurance Review and Assessment Service. We identified developments over the 5-year time period and analyzed the level of regional imbalance regarding cardiovascular surgery through the relative comparison of relevance indexes between cardiovascular and other types of surgery. Results: The relevance index was high in large cities such as Seoul, Daegu, and Gwangju, but low in regions that were geographically far from the capital area, such as the Gangwon and Jeju areas. Relevance indexes also fell as the years passed. Cardiovascular surgery has a relatively low relevance index compared to key types of surgery of other fields, such as neurosurgery and colorectal surgery. Conclusion: This study identified medical service use imbalance between regions for cardiovascular surgery. Results of this study demonstrate the need for political intervention to enhance the accessibility of necessary special treatment, such as cardiovascular surgery.

Objectives: To compare the health behaviors of widowed women with those of currently married women. Methods: We randomly sampled the subjects from the Jeollanamdo Resident Registration Data and we then selected 2,331 widowed women and 4,775 married women. Well-trained examiners measured the height, weight, blood pressure and abdomen circumference, and the women were interviewed with using a questionnaire. Logistic regression analysis was used to estimate the odds ratios(OR) of the two groups. Results: The smoking rate (OR=2.46; 95% confidence interval [CI]1.65, 3.66) was significantly higher for the widowed women. On the contrary, the awareness rate of a smoking cessation campaign (OR=0.80; 95% CI=0.70, 0.92), a quit tobacco telephone line (OR=0.73; 95% CI =0.61, 0.88) and a quit smoking clinic (OR=0.74; 95% CI=0.62, 0.89) were lower for the widowed women. The rate of receiving a health exam (OR=0.80; 95% CI=0.70, 0.91), the rate of undergoing gastric cancer screening (OR=0.77; 95% CI=0.68, 0.88), breast cancer screening (OR=0.79; 95% CI=0.69, 0.89), cervix cancer screening in the last 2 years (OR=0.81; 95% CI=0.71, 0.92), colon cancer screening in the last 5 years (OR=0.74; 95% CI=0.63, 0.87) were significantly lower for the widowed women. Conclusions: This study revealed that the health behaviors are significantly different between the widowed women and the married women. To improve the health behaviors of the widowed women, further study and research that will investigate the socioeconomic and environmental factors that affect the health behaviors of widowed women will be needed.

Although the majority of elderly are residentially stable, many western studies have recently reported that there has been a gradual growth of retirement migration. However, little is known about that in Korea. Therefore, this study intended to examine the trend and nature of elderly migration. For this purpose, inter- and intra-province migration among the aged 65 and over were analyzed, using the migration data of the Korea National Statistical Office, compiled from the 2000 and 2006 resident registration records. The results were as follows. First, there was an increase of elderly migrants to 531 thousand persons in 2006 from 383 thousand persons in 2000. Secondly, the migration rate of elderly has steadily grown with a 11.7% in 2000 and 12% in 2006. Also, the move of female among old population was active but this trend tended to decrease in 2006. Thirdly, the number of provinces which showed a positive net inter-province migration of old population increased from 7 provinces in 2000 to 8 provinces in 2006. Fourthly, we found that the destinations of elderly migrants were mostly neighboring province except the Chungnam, Jeonbuk, and Jeju. These results suggested that elderly migration would be expected to increase gradually and be important in the future of Korea.

This paper presents the findings of a study in which students at a four-year university were surveyed in an effort to analyze and verify the differences in perceived security awareness, security-related activities, and security damage experiences when using smartphones, based on demographic variables such as gender, academic year, and college major. Moreover, the perceived security awareness items and security-related activities were tested to verify whether they affect the students' security damage experience. Based on survey data obtained from 592 participants, the findings indicate that demographic differences exist for some of the survey question items. The majority of the male students replied "affirmative" to some of the questions related to perceived security awareness and "enthusiastic" to questions about security-related activities. Some academic year differences exist in the responses to perceived security awareness and security-related activities. On the whole, freshmen had the lowest level of security awareness. Security alert seems to be very high in sophomores, but it decreases as the students become older. While the difference in perceived security awareness based on college major was not significant, the difference in some security-related activities based on that variable was significant. No significant difference was found in some items such as storing private information in smartphones and frequency of implementation of security applications based on the college major variable. However, differences among the college majors were verified in clicking hyperlinks in unknown SMS messages and in the number of security applications in smartphones. No differences were found in security damage experiences based on gender, academic year, and college major. Security awareness items had no impact on the experience of security damage in smartphones. However, some security activities, such as storing resident registration numbers in a smartphone, clicking hyperlinks in unknown SMS messages, the number of security apps in a smartphone, and the frequency of implementation of security apps did have an impact on security damage.

Objectives： To examine the regional mortality differences in The Republic of Korea according to geographic location. Methods： All 232 administrative districts of the Republic of Korea in 1998 were studied according to their geographic locations by dividing each district into three categories； "metropolis," "urban," and "rural". Crude mortality rates for doth sexes from total deaths as well as the three major causes of death in Korea (cardiovascular disease, cancer, and external causes) were calculated with raw data from the "1998 report on the causes of death statistics" and resident registration data. Standardized mortality ratios (SMR) were calculated using the indirect standardization method. Poisson regression analyses were performed to examine the effects of geographic locations on the risk of death. To correct for the socioeconomic differences of each region, the percentage of old ($\geq$ 65 years old) population, the number of privately owned cars per 100 population, and per capita manufacturing production industries were included in the model. Results： Most SMRs were the lowest in the metropolis and the highest in the rural areas. These differences were more prominent in men and in deaths from external causes. In deaths from cancer in women, the rural region showed the lowest SMR. In Poisson regression analysis after correcting for regional socioeconomic differences, the risk of death from all causes significantly increased in both urban (OR＝1.111) and rural (OR＝1.100) regions, except for rural women, compared to the metropolis region. In men, the rural region showed higher risk (OR＝1.180) than the urban region (OR＝1.l51). For cardiovascular disease and cancer, significant differences were not found between geographic locations, except in urban women for cardiovascular disease (OR＝1.151) and in rural women for cancer (OR＝0.887), compared to metropolis women. In deaths from external causes, the risk ratios significantly increased in both urban and rural regions and an increasing tendency from the metropolis to the rural region was clearly observed in both sexes. Conclusions： Regional mortality differences according to geographic location exist in The Republic of Korea and further research and policy approaches to reduce these differences are needed. to reduce these differences are needed.

The cases of identification forgery and counterfeiting are increasing under the current identification system, which was established based on social conditions and administrative environments over 20 years ago. This leads to an increase of various criminal acts including illegal loan using fake ID and a number of damages caused out of good intentions that result in interference with the operations of public organizations. In addition, according to the advancement of information society, privacy protection has emerged as an important issue. However, ID card exposes individuals' personal information, such as names, resident registration numbers, photos, addresses and fingerprints, and thus the incidents associated with illegal use of personal information are increasing continuously. Accordingly, this study aimed at examining the issues of ID card forgery/counterfeiting and privacy protection and at proposing a next-generation identification system to supplement such weaknesses. The top priority has been set as prevention of forgery/counterfeiting and privacy protection in order to ensure the most important function of national identification system, which is user identification.

The value and importance of personal information are increasing due to the increasing number of fields where the Internet environment and computing environment are used, and user authentication technology is also changing. Until now, accredited certificates, which are mainly used in the financial sector, are being replaced with biometric authentication technology due to the problem of revocation. However, another problem is that biometric information cannot be modified once it is leaked. Recently, with the advent of blockchain technology, research on user authentication methods has actively progressed. In this paper, both public certificate and blockchain-based user authentication can be used without system change, and a new DID issuance and reissuance method that can replace the resident registration number is presented. The proposed system can be used without restrictions in a blockchain. However, the currently used DID requires installation of an application at the Interworking Support Center for verification. Since a DID can be authenticated without registering as a member, indiscriminate information collection can be prevented. Security, convenience, and determinism are compared with the existing system, and excellence is proven based on various attack methods, its portability, and proxy use.
