Given limited supply of approved vaccines and constrained medical resources, design of a vaccination strategy to control a pandemic is an economic problem. We use time-series and panel methods with real-world country-level data to estimate effects on COVID-19 cases and deaths of two key elements of mass vaccination - time between doses and vaccine type. We find that new infections and deaths are both significantly negatively associated with the fraction of the population vaccinated with at least

We estimated the economic burden of cancers attributable to metabolic syndrome in Korea and the efforts are necessary to reduce this burden.

There has been a recent increase in interest in NFTs, as the number of high-priced trades has risen. While some research attempts to identify the factors behind these value spikes using traditional market analysis and machine learning, few studies focus on the user-driven communities where vast amounts of information are shared. We aim to address the need for understanding the factors that influence NFT prices within user-driven communities, specifically within Discord, an influential platform f

최근의 사이버 공격은 내부 직원을 목표로 하거나 불특정 다수의 PC를 이용하는 등 지능화, 대규모화 되고 있어 기술적인 보안대책만으로 대응하는데 한계가 있으며, 관련 인력이 중심이 되는 종합적인 대책이 필요하다. 그러나 정보보호 전문 인력을 양성하는데 있어서 근간이 되는 국내의 정보보호 교육체계는 정보보호 교육 중장기 계획 부재, 교육 프로그램에 대한 검증 부족, 교육기관 간의 정보 교류 부재 등 여러 가지 문제점을 가지고 있다. 본 논문에서는 국내 정보보호 교육체계의 문제점을 해결하고 사이버 정보보호 환경을 개선하기 위한 정보보호 교육 발전 방안을 제안한다. 본 논문에서 제안하는 정보보호 교육체계 발전 방안은 국가 정보보호 교육 마스터플랜의 기획 및 추진, 정보보호 교육 프로그램 인증제도 도입, 정보보호 전문인력 DB 운영, 정보보호 전문 인력에 대한 다양한 혜택 개발 등의 세부 방안을 포함한다. There is a limitation on counteracting recent c

Constipation is a common disease that reduces life quality. Drugs of various mechanisms are being developed to resolve this affliction. Intestinal motility can be easily monitored in zebrafish, and so we selected this organism to develop a constipation model to measure drug-induced prokinetic effects. In this study, intestinal motility was monitored in zebrafish by tracking intestinal transit using fluorescence, after which an opioid-induced constipation model was established using loperamide. W

A majority of career teachers in Missouri defined benefit pension plan reach their pension wealth peak before their 31st year of service. The 2002 pension enhancement in Missouri generates a local gain in pension wealth that is lower than the peak and also creates an eligibility milestone at the 31st service year. To test whether the 31st year enhancement affects retirement timing decisions for mid- to late-career teachers, I use administrative data of Missouri teachers and employ difference-in-

This study investigates the impact of watching motives of parenting reality TV Program, (MBC), (KBS2) on user satisfaction and rewatching. Viewing motives of parenting reality TV Program are found as 'interest', 'charm of children characters', 'relief of loneliness' and 'express everyday feelings'. The result shows that there is significant difference in watching time according to the factor of 'charm of children characters'. Also 'interest' and 'expression of everyday feelings' affect viewing s

Objectives: Metabolic syndrome is an important etiologic factor in the development of certain types of cancers. The economic cost of the treatment of cancer has been steadily increasing. We therefore estimated the economic burden of cancers attributable to metabolic syndrome in Korea. Methods: We reviewed metabolic syndrome-related cancers and relative risk and then calculated population attributable fractions. We analyzed insurance claims data for metabolic syndrome-related cancers in 2012 in o

The extent of damage to a community from an earthquake depends on the existing road infrastructure and space for disaster response activities. The Bureau of Urban Development of the Tokyo Metropolitan Government has assessed the seismic vulnerability and risk to communities, and announced the results approximately every five years since 1975. The present study investigates the assessment methods used last three times by focusing on the emergency response difficulty coefficient. The methods are t

This paper examines the effects of neoliberalism in Mexico undertaken during the administration of Carlos Salinas leading to the North American Free Trade Agreement in 1994. The effects of neolibralist policy on common people as well as resistance to the administration’s policies are examined in depth.
