Objectives: There is an increasing number of North Korean adolescents in South Korea. These adolescents need clinical attention as they experience a high risk of suicidal behavior because of the childhood adversity and acculturative challenges that they face before and after arriving in South Korea. This study assessed the risk of suicide attempts among North Korean adolescents compared to South Korean adolescents, and investigated the contributing factors for each group. Methods: We used data from the Korean Youth Risk Behavior Web-Based Survey (KYRBS) spanning 2011 to 2018, in which 404 adolescents had a father and/or mother who was a North Korean native. Data on 1,212 propensity-matched South Korean adolescents were extracted from the 2011 to 2018 KYRBS. Prevalence was calculated and compared by group. Separate odds ratios were calculated by group. Results: The North Korean group had a significantly higher suicide attempt rate [unadjusted odds ratio (OR)=8.27; adjusted OR=8.45]. Multivariate analysis indicated that having a low or high socioeconomic status and depressive symptoms were significantly associated with suicide attempts in North Korean adolescents, while being female, having a high socioeconomic status, alcohol use, and depressive symptoms were significantly related to suicide attempts in South Korean adolescents. Conclusion: The results found similarities and differences in the factors associated with the likelihood of suicide attempts in the two groups. From these results, different approaches are needed when planning interventions for each group.

SNe light curves have been used to understand the expansion history of the universe, and a lot of efforts have gone into understanding the overall shape of the radioactively powered light curve. However, we still have little direct observational evidence for the theorized SN progenitor systems. Recent studies suggest that the light curve of a supernova shortly after its explosion (< 1 day) contains valuable information about its progenitor system and can be used to set a limit on the progenitor size, R*. In order to catch the early light curve of SNe explosion and understand SNe progenitors, we are performing a ~8hr interval monitoring survey of nearby galaxies (d < 50 Mpc) with 1-m class telescopes around the world. Through this survey, we expect to catch the very early precursor emission as faint as R=21 mag (~0.1 Rsun for the progenitor). In this talk, we outline this project, and present a few scientific highlights, such as the early light curve of SN 2015F in NGC 2442.

The Korean Astronomical Society (KAS) Education & Public Outreach Committee has provided education services for children and school teachers in Cambodia over the past three years from 2016 to 2018. In the first year, 2016, one KAS member visited Pusat to teach astronomy to about 50 children, and in the following two years of 2017 and 2018, three and six KAS members, respectively, executed education workshops for ~ 20 (per each year) local school teachers in Sisophon. It turned out that it is desirable to include both teaching of astronomical knowledge and making experiments and observations in the education in order for the program to be more effective. Language barrier was the main obstacle in conveying concepts and knowledge, and having a good interpreter was very important. It happens that some languages, such as the Khmer of Cambodia, do not have astronomical terminologies, so that lecturers and even the education participants together are needed to communicate and create appropriate words. Handout hard-copies of the education materials (presentation files, lecture/experiment summaries, terminologies, etc.) are extremely helpful for the participants. Actual performing of assembling and using astronomical telescopes for night sky observations has been lifetime experience for some of the participants, which might promote zeal for knowledge and education. It is hoped that these education services for developing countries like Cambodia can be regularly continued in the future, and further extended to other countries such as Laos and Myanmar.

The progenitor of Type Ia supernovae is largely expected as a close binary system of a carbon/oxygen white dwarf (WD) primary and its secondary non-degenerate (single degenerate; SD) or degenerate companion (double degenerate; DD). Here we present a high-cadence monitoring observation of SN 2021hpr in a spiral galaxy, NGC 3147. SN 2021hpr shows typical characteristics as a normal type Ia supernova from its photometric (Δm₁₅(B)=1.01±0.03, dust free M_B,max=-19.45±0.02) and spectroscopic data. To investigate its progenitor system, we fit the early part of BVRI-band light curve simultaneously with a combined version of ejecta-companion and simple power-law model. As a result, we found a significant feature of an early excess possibly from a 7.63±0.52R_⊙-sized companion at the optimal viewing angle while the fit is not successful at the common viewing angle. No possible red sources brighter than F555W=-7.01 AB mag is detected at the SN location in Hubble Space Telescope (HST) pre-explosion images, excluding massive stars with initial mass of >16M_⊙ as companions. We suggest the progenitor system of SN 2021hpr can be a fairly large companion such as a main sequence, a low mass subgiant, and a helium giant star. In addition, a possibility of the ejecta-Disk Originated Matter (DOM) interaction for the DD scenario considering linearly-rising early flux still remains.

본 연구는 성남시 청년배당 지급조례를 기본소득 실현 사례로 설정하여 그 도입에 있어서 문화복지위원회 회의록을 규범과 경험의 정책기준으로 분석한 결과다. 주요 문장을 질적 코딩하여 재분류하는 분석방법을 응용하였다. 규범적 차원에서 찬성논의는 사회정의를 실현하는 목적으로 청년배당을 이해한다. 또한 원리적으로 기존정책을 대체할 수 있다고 본다. 반면 도덕적으로 정당하지 아니하며 정책의 비교 우위에 대한 모호성과 수단의 비효율성 등 원리적, 수단적 차원에서 반대 논의가 제기된다. 경험적 차원에서 찬성논의는 사회적 배려대책으로 이해하며 기존 대책의 기능부전에 따른 혁신적 정책 도입에 초점을 두고 있다. 반면 반대논의는 목표 효율성과 급여 내용에 대한 문제를 들고 있다. 양측이 너무 대조적이므로 합의는 어려우며 정치적 진영 논리가 중요 변수가 될 수 있다. 기본소득은 인간의 자기실현에 대한 새로운 사고실험이므로 생산주의 복지정책과는 다른 정책과학이다. 즉 총체적 생활지원을 요구하는 돌봄의 사회정책을 제한 조건으로 하는 실질적 자유를 위한 물질적 지원을 고려하는 비경험적 정책이다. 기존의 정책 과학적 평가 이전에 자율적인 삶의 실현을 지향하는 그 자체의 철학적 의미에 대한 이해와 복지 정치와 운동을 통한 정체성 알리기는 여전히 중요한 전략이 될 것이다.

The purpose of this paper is a case study on welfare QC circle which is considered as one of the management techniques to improve service quality among recently changing welfare environment. Futhermore this paper is also to suggest a new introduction of the welfare QC circle in korean social welfare agency. To accomplish these purpose, this study theoretically examines activity process and techniques of welfare QC circle. In practice, three social workers and one supervisor working at 'D' community welfare center in pusan are participated during six months. As a result, we founded the specific problems that is aroused from youth volunteer group within by fish bone chart, and proposed the alternative choices by 5W1H check sheet, and also certified to decrease turnover ratio in youth volunteering by pareto chart. This study, however, has its limitation in selection only one case study on welfare QC circle of youth volunteering. Welfare QC circle could be much contributed as one of the management techniques to enhance the quality of social welfare service from the viewpoint of the customer, If it is well developed korean welfare QC model which is suitable to social welfare organization and service. Therefore, in order to introduce welfare QC circle in korean social welfare organizations, I would like to suggest to find out a useful text of welfare QC and organize some welfare QC study groups including other suggestions.
