A multilevel analysis of social capital and self-reported health: evidence from Seoul, South Korea
No full textAbstract Background This study aims to resolve two limitations of previous studies. First, as only a few studies examining social capital have been conducted in non-western countries, it is inconclusive that the concept, which has been developed in Western societies, applies similarly to an Asian context. Second, this study considers social capital at the individual-level, area-level and cross-levels of interaction and examines its associations with health while simultaneously controlling for various confounders at both the individual-level and area-level, whereas previous studies only considered one of the two levels. The purpose of this study is therefore to examine the associations between social capital and health by using multilevel analysis after controlling for various confounders both at the individual and area-levels (i.e., concentrated disadvantage) in non-western countries. Methods We conducted a cross-sectional survey from December 2010 to April 2011 in Seoul, South Korea. The target population included respondents aged 25 years and older who have resided in the same administrative area since 2008. The final sample for this study consisted of 4,730 respondents within all 25 of Seoul's administrative areas. Results In our final model, individual-level social capital, including network sources (OR = 1.23; 95% CI = 1.11-1.37) and organizational participation (OR = 2.55; 95% CI = 2.11-3.08) was positively associated with good/very good health. Interestingly, the individual × area organizational participation cross-level interaction was negatively associated with good/very good health (OR = 0.40; 95% CI = 0.32-0.50), indicating that in areas with higher organizational participation, individuals with high organizational participation were less likely to report good/very good health when compared to low organizational participation individuals. Conclusion Our study provides evidence that individual-level social capital is associated with self-reported health, even after controlling for both individual and area-level confounders. Although this study did not find significant relationships between area-level organizational participation and self-reported health, this study found the cross-level interaction for social capital. Hence, in areas with lower organizational participation, the probability of reporting good/very good health is higher for individuals with high organizational participation than individuals with low organizational participation. This study, albeit tentatively, suggests that policy makers should focus upon social capital when making policies which aim to enhance one's health.</p
Design of Physically Unclonable Function Using Ferroelectric FET With Auto Write-Back Technique for Resource-Limited IoT Security
No full textPhysically unclonable function (PUF) is a lightweight encryption technique that generates random digital keys (responses) using intrinsic process variations of devices, which is a promising solution for Internet of Things (IoT) security due to its compatibility with constrained resources. Recent attempts to adopt nonvolatile memory (NVM) into PUFs have enhanced stability through a write-back technique that maintains consistent responses from the enrollment phase even under wide environmental variations by storing the response in the NVM device. However, the stability of the previous NVM PUFs is limited by the low-on/off ratio of the NVMs. In addition, the circuit required to implement the write-back technique poses challenges of increased area and energy consumption. Considering the hardware limitations and power constraints of IoT devices, this article proposes a ferroelectric field-effect transistor (FeFET) PUF as a suitable security solution. The high-on/off ratio of FeFET and the proposed auto write-back technique that does not require additional circuitry realize the stability improvement (a bit error rate of <0.0001%) under wide environmental variations without incurring area and energy overheads. The negligible off current of FeFET prevents static power consumption, which leads to the lowest energy consumption of 6.70e(-15 )J during the response generation of the FeFET PUF. In addition, the compact PUF cell composed of two FeFETs achieves a high density of 87.37 F-2.

The Impact of Covid-19 and its policy response on Korea's export
No full textThesis(Master) -- KDI School: Master of Public Policy, 2021The lockdown policies, which are composed of various measures like workplace closing, cancel public events, stay-at-home requirements, are adopted to block the transmission of COVID-19. It may succeed in blocking the infections, but it has negative impacts on the global economy in terms of production and consumption. In this research, the author tries to focus on the impacts of COVID-19 and its policy responses on Korea’s exports by using COVID-19 case and death data, policy response data from OxCGRT, immobility data from Google. The importing countries’ COVID-19 and the policy responses have negative impacts on Korea’s exports even though some of the indicators are not statistically significant. Also the country groups such as OECD, EU, ASEAN, and OPEC have shown the mitigation of negative impacts of COVID-19 and its policy responses and immobility. Korea’s COVID-19 situation, its policy responses and immobility in the workplace have positive impacts on Korea''s exports. The author also tries to check the baseline’s results by doing the estimation with product division, adding time-lag variables, and dividing the region by capital and non-capital area and confirms that the direction of coefficients except medical industries. This study contributes to suggest rough ideas about the impact of lockdown measures on Korea’s exports.I. Introduction

SOCIAL CAPITAL AND MENTAL HEALTH IN SEOUL, SOUTH KOREA: A MULTILEVEL ANALYSIS OF 4,734 PEOPLE IN 25 ADMINISTRATIVE AREAS
No full textAnat as a precursor of Lady Wisdom in Proverbs 8:22–31
No full textThis dissertation investigates the identity of Lady Wisdom, the enigmatic figure in Proverbs 8:22–31. The presupposition of this investigation is a widely shared expert interpretation, namely, that Lady Wisdom is a multifaceted female divine figure whose origin and characteristics are interwoven with those of a number of ancient Near Eastern goddesses. The main contribution of this project is to argue that the Ugaritic goddess Anat be considered a possible precursor of Lady Wisdom. According to the author, a fluid and complementary relationship exists between Lady Wisdom’s depiction in the Hebrew Bible and Anat’s depiction in ancient Near Eastern religions, especially since certain aspects of their origin, status, and function are similar. The project also sheds light on the pivotal role of Lady Wisdom as a co-creator and mediator of the heavens and the earth. She should be regarded as a co-creator who is an active and mobile participant in God’s creative work; she is found not only in Proverbs but also in other biblical and deuterocanonical traditions. Moreover, she is a perfect mediator not only between the creation traditions and wisdom literature but also between the divine and human realms. Her mysterious identity is manifested in her own words and in others’ descriptions of her. Humans can either accept or reject Lady Wisdom, but only those who recognize and appreciate her divine knowledge are able to embrace truth in their lives
Familiarity with Big Data, Privacy Concerns, and Self-disclosure Accuracy in Social Networking Websites: An APCO Model
No full textSocial networking websites have not only become the most prevalent communication tools in today’s digital age but also one of the top big data sources. Big data advocates promote the promising benefits of big data applications to both users and practitioners. However, public polls show evidence of heightened privacy concerns among Internet and social media users. We review the privacy literature based on protection motivation theory and the theory of planned behavior to develop an APCO model that incorporates novel factors that reflect users’ familiarity with big data. Our results, which we obtained from using a cross-sectional survey design and structural equation modeling (SEM) techniques, support most of our proposed hypotheses. Specifically, we found that that awareness of big data had a negative impact on and awareness of big data implications had a positive impact on privacy concerns. In turn, privacy concerns impacted self-disclosure concerns positively and self-disclosure accuracy negatively. We also considered other antecedents of privacy concerns and tested other alternative models to examine the mediating role of privacy concerns, to control for demographic variables, and to investigate different roles of the trust construct. Finally, we discuss the results of our findings and the theoretical and practical implications
