Manjae Kwon,Young-Chul Jung,Deokjong Lee,Jaeun Ahn 대한신경정신의학회 2023 PSYCHIATRY INVESTIGATION Vol.20 No.1
Objective We aimed to elucidate public mental health problems and associated factors during the coronavirus disease-2019 (COVID-19). Furthermore, we evaluated people’s attitudes toward digital therapeutics during the pandemic. Methods Data was collected online from participants, aged between 20–50 without any history of mental illness, from June 1st to June 30th 2021. The survey consisted of questions regarding demographics, changes during pandemic and attitude towards digital therapeutics, and mental health measures. Results Among the total of 445 participants, 49.2% reported significant level of stress and 13.5% and 7.0% met the screening criteria for major depressive disorder and generalized anxiety disorder, respectively. Significant predictive factors for mental health problems were-younger age group, female sex, currently being treated for medical or surgical disease, change in the amount of time spent on mobile device or computer after pandemic, change in household income, and change in work environment due to pandemic. Furthermore, 35.1% of participants, considered psychiatric consultation, at least slightly, but were hesitant to receive it due to the fear of contacting COVID-19 at the clinics. Instead, 54.4% of them preferred using digital therapeutics as an alternative to visiting offline clinics. Conclusion We demonstrated that COVID-19 increased mental health problems along with access problems and identified their predictive factors. Digital therapeutics emerged as a viable solution to mental health problems and it was well-received by those in need of psychiatric consultation. Therefore, development and implementation of digital therapeutics should be considered to improve the mental health of people.
COMPARING HOUSING POLICIES IN TOKYO AND SEOUL
KIM, MANJAE Institute for Social Development and Policy Resear 1995 Korea Journal of Population and Development Vol.24 No.1
This paper analyses housing policies in Tokyo and Seoul from comparative perspectives. First, unlike production, the state in Japan and Korea has not played an active and effective role in the housing sector. Second, the state in the West has been more concerned about housing than Japanese and Korean states, and the local state in the West has also pursued more independent housing policies than the Tokyo and Seoul Metropolitan Governments. Third, in spite of their similarities at the macro level, Japanese housing policies have been more quality and equality oriented than Korean housing policies.

Purpose: Lead has been widely used in radiation shielding for its low price and high workability. Recently in several europe countries, use of lead was banned for environmental issues. Also lead can cause health problems like alergies. Alternative materials for lead are highly required. The purpose of this study was to propose lead free radiation shielding material. Methods: Research of radiation shielding in Korea is not easy for certain limits such as radiation materials, experimental facilities and places. The collected data through the research were simulated using MCNPX. The simulation tools used for this study were utilized Monte Carlo method. Results: we suggest new design of lead free radiation shielding material using MCNPX code comparing shielding performance of new composite materials to lead. Conclusion: This newly introduced nano-scale composite of metal and polymer makes new chance for highly lightened radiation protective garments with endurable shielding performance.
CR X-선 영상기법을 이용한 DPF 파손여부에 대한 비파괴 측정 타당성 연구

Diesel vehicles are equipped with after-treatment devices, such as DPF. Meanwhile, DPF is damaged by a combination of regenerative processes and unclear factors. If the DPF substrate is damaged, the filtration performance will deteriorate, thereby resulting in excessive levels of fine dust being emitted while driving. In this study, CR X-ray techniques were used in order to determine whether a DPF was damaged without prior removal. In order to verify the technological feasibility, an X-ray imaging of the DPF removed from the driving vehicle was conducted by using an X-ray generator, as well as an IP reader and a CR reader. Optimal irradiation conditions were established for each DPF size. Verification of images acquired under optimal irradiation conditions confirmed the possibility of diagnosis for damages, such as crack, melting, and hollow damage.
