One view in the study of attitudes towards immigration is that public reactions depend on who the immigrants are. Using a survey experiment, we confirm that group cues matter: South Koreans are more likely to support liberal immigration policies, when immigrants are framed as North Korean defectors (coethnic group). When other groups cues—Korean Chinese (semi-coethnic group) or guest-workers from Indonesia (non-coethnic group)—are given, the level of support becomes significantly lower. Apparent

When cultural tastes are not neutral but hierarchically matched to social status, people assimilate themselves to higher status by consuming cultural goods while distinguishing themselves from lower status by developing new tastes. Extending the Cucker-Smale model for mutual influence among agents, we examine when and how many cultural classes emerge from continuous distributions of tastes and what conditions those classes satisfy, through the assimilation-distinction mechanism. We simulate the

McDonald and Moffitt's (1980) decomposition method for Tobit coefficients disaggregates the total changes in a censored outcome variable into the changes in the probability of attaining noncensored values and the changes in the noncensored values themselves. McDonald and Moffitt, however, did not highlight two limitations of this decomposition, and sociological applications of the Tobit decomposition that do not acknowledge these limitations have been misleading. First, the decomposition ratio o

본 연구는 장애인 실업자의 어떤 구직 노력이 취업 확률을 높이는지, 취업 장애인의경우 어떤 취업경로가 더 높은 임금과 연결되는지를 사회적 연결망의 유형별 효과에 초점을 두고 살펴 보았다. 사회적 연결망의 유형을 크게 친밀 연결망과 지인 연결망으로구분하고, 전자는 결속된 연결망 구조를 바탕으로 하는 후원효과를 통해 취업에, 후자는열린 구조를 바탕으로 하는 정보효과를 통해 임금수준에 긍정적 영향을 미칠 것으로 보았다. 한국장애인고용공단의 장애인 고용패널조사 2008년 1차부터 2011년 4차까지의데이터를 이용해 종단분석한 결과, 구직자의 취업 여부에는 사회적 연결망의 효과가 미미했고, 취업자의 임금 수준에는 기대한대로 후원 효과보다는 정보 효과가 나타났다. 상술하자면, 취업여부에는 친밀 연결망과 지인 연결망 모두 효과가 유의하지 않고 주로 장애등급의 효과가 압도적이었으며, 취업자의 경우 가족, 친척, 선후배 등 친밀 연결망의소개를 통해 취업한 경우보다 업무상 지인 연결망을 통해 취업한

In what traits do people interact with others who are similar to them in completely anonymous online communication? Can those traits contribute to greater exchange of opinion and information across the sociodemographic boundaries that often limit interaction between social strata? To answer this question concerning online homophily, we combined survey data on 7,287 users (aged 18 and above) of a Korean online dating advice platform with their behavioral data from June 2015 to August 2015 and exp

Our data shows that MVD may be a good treatment modality for HFS caused by VBD but care must be taken to avoid adverse effects from the procedure. It is important to detach the dolichoectatic artery from its surrounding structures sufficiently to allow it to be easily movable. In addition, attempts should be made to lessen the retraction of the cerebellum during release of the dolichoectatic artery.

Although having a variety of roles is generally beneficial for mental health, little is known about the relationships between work-family role combinations and depressive symptoms among married women in Korea, where child rearing is strongly considered a mother's responsibility. This study examines how the four types of work-family role combinations may be associated with depressive symptoms among married Korean women younger than 50 years old. Data were collected from 2012 through 2020 in five

The extent of resection and release of the trachea is important for successful anastomosis. Bilateral bronchial dissection is one of the release techniques for resection of the lower trachea. We present the experience of cervical video-assisted mediastinoscopic bilateral bronchial release for long segmental resection and anastomosis of the lower trachea.

This study explores how digital technologies can benefit older adults’ cognitive health. The need for cognition (NFC) refers to an individual’s tendency to engage in and enjoy cognitive endeavors and is an explanatory variable for behavioral outcomes. To date, little scholarly literature has examined how NFC can be affected by our behavior; therefore, this study explored whether practicing digital skills can help to improve or maintain NFC. Utilizing age as an instrumental variable, we analyzed

We report on an unusual case with infiltrating extradural spinal angiolipoma. Most spinal angiolipomas involve the thoracic spine and infiltrating ones are also located mainly at the thoracic levels rather than lumbar lesion. In particular, there are few cases of lumbar extradural infiltrating type spinal angiolipoma. One case is that of a 52-year-old female with infiltrating extradural spinal angiolipoma involving lumbar 4 (L4) vertebra, who underwent a L4−5 laminectomy and surgical removal of

Abstract This study examines how citizens' attitudes toward government are affected by verifying or correcting their prior knowledge of governmental policy concerning the COVID‐19 pandemic. Using a survey experiment, we asked respondents about their knowledge of the stimulus check provided by local governments in South Korea. We then provided the correct answer to half of the respondents at random. For outcome variables, we measured satisfaction with the stimulus check, trust in the government,

This study investigated whether and how classroom-level bullies' friendship networks, which reflect the popularity of bullies, were associated with the self-esteem of middle school students in the classroom. We analyzed survey data from 2,444 students in 101 classrooms from 22 middle schools in Korea. Respondents reported their friends' and bullies' names from their classroom. For each student, we generated the number of close friends that a respondent reported (outdegree) and the number of clas

Web 2.0 시대의 도래와 SNS 서비스를 통한 교류의 폭발적 증가는 온라인 데이터를 이용해 사람 간 상호작용이나 관계에 대한 통찰을 넓힐 수 있는 기회를 가져다주었다. 그러나 이러한 온라인 네트워크 데이터의 폭발적 증가는 네트워크 연구를 계산능력에 의존한 속도경쟁으로 이끈 측면이 있으며, 가상세계의 인간관계에 대한 이론적 통찰보다는 대규모 데이터의 효율적 지표화, 다양한 네트워크 구조를 가로지르는 공통의 패턴이나 연관관계, 즉 법칙의 발견에 주목해온 면이 있다. 이러한 흐름 속에서 온라인 인간관계에 대한 사회과학적 연구는 다소 혼란스런 모습을 보이고 있는데, 본 연구는 멱함수 법칙으로 대변되는 연결 분포의 불평등성을 중심으로 사회과학적 이론화 작업을 세 가지 학제적 측면에서 제안한다. 우선, 면대면 관계와 온라인 관계의 형성원리에 대한 통합적 이해는 멱함수 분포의 이면에 있는 정규분포적인 상호작용의 차원을 밝히는 것과 연관되어 있음을 보이고 경험적 예를 제시한다. 이를 위해 파레
