This paper tried to examine the relationship between social network patterns and physical health statuses among junior high school students in Korea with three distinctive characteristics with compared to many previous studies. First, based on two-year panel data of Korean Youth Panel Survey, it tried to control for unobserved heterogeneity that might have been exerting effects on students’ health but could not have been included in the survey. Furthermore, instead of typical random model of anel data, it employed a modified random model that examined each coefficient to decide if we could treat ‘between’ effect same as ‘within’ effect. Thanks to this modified model, we could detect getting along with friends at school had only ‘between’ effect without statistically significant ‘within’ effect. Lastly, by including self-perceived psychological problem in the regression, we examined the possibility of direct network effects on physical health. The results revealed that in each of three social dimensions (school, family, and friends) direct effects of network existed on physical health of junior high school students. Especially, cohesive and frequent interacting with friends rather than simple popularity among friends was closely related with physical health.

5,728 bills were proposed by cosponsoring legislators during 17<SUP>th</SUP> Korean National Assembly. Based on the score for broker position of each legislator is calculated from co-sponsorship networks, this paper examines the effects of brokerage on the adoption of bills. Unlike many studies that confirmed consistent benefits of brokers in economic situation, we find it was not always the case in political sphere. The benefit of brokers is dependent on both broker types and the extent of political tension. Depending on these two factors, brokers sometimes even got penalty not benefit. First, the effect of each brokerage is biggest when the political confrontation is medium. In other words, if political confrontation is too weak or too strong, the change in brokerage score does not change the adoption rate a lot. When political conflict is too low or too high, there is little room for brokers. Brokers need moderate level of confrontation in order to obtain benefit from brokerage acts. If confrontation is too weak, parties do not need brokers. They can persuade other legislators to adopt bills they want without brokers’ help. If confrontation is too strong, parties do not want brokers: brokers are treated as opportunistic. Second, when we compare the size of the effects between different types of brokerage, inside and in-and-out brokerage produces the best results. We can conclude that in order to get maximum benefit out of broker positions, you need to bridge two legislators at least one of whose party membership is identical to yours.

Systematic review of Barth and colleagues on the studies of social support and coronary heart diseases(CHD)(Barth, Schneider & Von Känel, 2010) have examined the effects of two types of social supports: functional and structural. The authors have concluded that functional social support was proved to be effective while there was no robust evidence for the influence of structural social support. The goals of this study were: 1) to re-examine Barth’s analysis for structural social support with more refined types of structural social supports - marital status, living alone, social network size, social engagement and composite index of structural social support - and 2) to review more recent articles about social support and CHD. Meta-analyses were performed by each type of structural social support from the total of 44 prospective studies - 25 from Barth’s review, and 19 new studies on social support and CHD. The results showed enough evidence for the effects of functional social support on CHD but not in the case of structural social support, which confirmed previous conclusion of Barth. This conclusion does not override the effects of structural social support, and more elaborated measures of social network structure are waiting to be tested in future studies.

This paper reviews the topics and methodologies of the 334 papers published in the journal, “Health and Social Science” for the last 20 years. We conducted classical quantitative content analysis and topic modeling using Structural Topic Model (STM) to identify the topics. The findings of this study were summarized as follows: (1) the social epidemiology research has steadily been increased while the studies on the health-related institutions and policies has been dropped, (2) the quantitative research had grown and consisted of 84% of the total studies by 2012 and dropped to 65%. Throughout the period, the researches on physicians, patients, and hospitals were rarely conducted. The lack of studies on the diseases and the limitations of data collection were remained as one of the major problems to be solved. 이 글에서는 지난 20년간 [보건과 사회과학]에 게재된 논문 334편을 분석하여 시기별 연구주제 및연구방법론의 동향에 대해 알아보았다. 고전적 내용 분석 방법을 사용해 분석한 결과 ‘사회역학’ 분야의 논문들은 지속적으로 증가하고 있는데 비해 ‘의료 제도와 정책’ 분야의 논문들은 점차 그 비중이줄어들고 있으며, ‘의사, 병원, 환자’에 관한 연구는 지속적으로 적은 사례만을 보여주었다. 구조적 토픽 모델(STM)을 이용하여 논문 전문(全文)을 분석한 결과에서는 ‘의료인력, 건강보험, 보건소, 보건관련 집단과 기관 그리고 프로그램’, ‘음주 및 흡연’노, 동‘ 자와 정신건강’, ‘청소년 및 대학생’ 등 네 가지 토픽 네트워크들을 확인할 수 있었다. 두 가지 분석방법을 활용해 도출한 결과는 상호보완적인 것으로 판단된다. 연구방법론에 있어서는 지속적으로 증가하여 84%까지 차지하였던 양적연구방법을사용한 논문들이 2013년 이후 65%까지 줄어들면서, 비실증연구나 질적연구방법을 사용한 연구가 증가세를 보이고 있다. 분석 결과 최근 보건사회학 분야가 독립적인 연구주제를 확립해 가는 과정에 있음을 추론할 수 있었다. 반면, 전문성이 필요한 신체질환에 대한 연구나 종단연구의 부족 등은 아직해결해야 할 과제로 해볼 수 있다.

The steering committee of the Korean Academy of Medical Sciences Guideline for Physical Impairment was fully aware of the social processes of disability evaluation from the beginning and thus, developed a series of strategies to examine and incorporate social property of the evaluation into the evaluation guide. Although those strategies could not be implemented to full extent because of lack of budget and time, we believe it worthwhile to share those in this paper as an example of general framework for developing disability evaluation. A series of strategies will be introduced and discussed that views the evaluation process as social per se, and propose a scheme that is designed to obtain growing legitimacy starting from core experts to expanded experts to general public. Also preliminary analyses on surveys of public attitude and experts’ opinion with regard to the relative importance of each possible disability revealed the following three facts: 1) Public had difficulty weighing relative importance of many impairments. 2) Regarding some impairments including complex regional pain syndrome many doctors had varied opinions. 3) Public attitude did not always consistent with doctor’s opinion. All these findings strongly suggest the need for developing strategies to draw consensus for legitimate and effective evaluation.
