Tobacco Use: A Major Risk Factor of Intracerebral Hemorrhage

Sunjoo Cho,Ashish K. Rehni,Kunjan R. Dave 대한뇌졸중학회 2021 Journal of stroke Vol.23 No.1

Spontaneous intracerebral hemorrhage (sICH) is one of the deadliest subtypes of stroke, and no treatment is currently available. One of the major risk factors is tobacco use. In this article, we review literature on how tobacco use affects the risk of sICH and also summarize the known effects of tobacco use on outcomes following sICH. Several studies demonstrate that the risk of sICH is higher in current cigarette smokers compared to non-smokers. The literature also establishes that cigarette smoking not only increases the risk of sICH but also increases hematoma growth, results in worse outcomes, and increases the risk of death from sICH. This review also discusses potential mechanisms activated by tobacco use which result in an increase in risk and severity of sICH. Exploring the underlying mechanisms may help alleviate the risk of sICH in tobacco users as well as may help better manage tobacco user sICH patients

조선주(Cho, Sunjoo),오현경(Oh, Hyun Kyung) 한국비영리학회 2013 한국비영리연구 Vol.12 No.1

베이비붐 세대의 은퇴와 더불어 유산기부, 다양한 자산기부를 포함하여 여생의 자산관리와 기부를 함께 계획하는 계획기부에 대한 관심이 높아지고 있다. 이에 본 연구는 재정패널 1-4차 자료를 사용하여 베이비부머의 기부특성을 분석하고, 실증분석을 통해 베이비부머일수록 기부금이 증가하는 지, 기부에 어떤 요인들이 영향을 미치는 지를 분석하여 기부정책 개선의 근간을 제공하는 것을 목적으로 한다. 분석결과 베이비부머의 연평균 기부금은 195만원, 이외 가구는 156만원으로 베이비부머의 기부금이 약 40만원 높은 것을 알 수 있었다. 이는 4년 전(2008년) 비해 각각 22만원, 18만원이 증가한 금액이다. 아울러 실증분석 결과 베이비부머가 기부금을 증가시키는 확률이 높은 것으로 나타났다. 이외에 가구의 연간소득, 학력, 임금 근로자 여부, 성별이 기부금에 유의미한 영향을 미치는 것으로 나타났다. 자료의 제약 등으로 인한 한계를 감안하더라도 본 연구결과는 베이비부머가 기부영역에 중요한 영향을 미칠 수 있으며, 기부정책이 사회변화로 인한 특정 세대나 집단의 기부, 즉 기부자의 특성을 반영한 다원화, 맞춤형 정책으로 변화해야한다는 의미로 해석할 수 있다. The purpose of this study is to analyze the charitable giving patterns of Korean Baby Boom Generation and to identify factors affecting their donating behaviors using Korean National Survey of Tax and Benefit Data. To conduct the empirical analysis, we use ‘Control Function Estimator’ method. The findings reveal that the Baby Boom Generation donated ￦1.95million on average in 2012 which was ￦0.4million higher than that of other generations’ average donation amount(￦1.56million). The amounts of donation have increased by ￦0.22million in the Baby Boom Generation and ￦0.18million in other generations respectively compared to the year 2008. The fact that one belongs to the Baby Boom Generation increased the likelihood of charitable giving. Also household’s annual income, one’s education level, full-time employment, one’s sex turn out to have significant effects on one’s charitable giving. The results imply that the donation related policies need to reflect the characteristics of donors and to be more flexible accommodating such diversity among donors.

특수형태근로부문의 레미콘운송종사자와 골프장경기보조원의 소득결정요인에 관한 연구

조선주(SunJoo Cho),최윤영(YunYoung Choi) 한국노동연구원 2008 노동정책연구 Vol.8 No.4

본 연구는 특수형태근로종사자 중에서 종사상의 성별 특성이 뚜렷한 ‘레미콘운송종사자’, ‘골프장경기보조원’의 인적 특성, 소득실태 등을 분석하고, 소득결정요인을 분석하였다. 분석 결과 특수형태근로종사자(레미콘운송종사자, 골프장경기보조원)의 경우 성별이 소득에 영향을 미치는 것으로 나타났으며, 교육연수, 연령, 근무지 및 상해보험 가입 여부가 소득에 영향을 미치는 것으로 나타났다. 특히 레미콘운송종사자의 경우 근무지와 상해보험 가입유무만이 소득에 통계적으로 유의미한 영향을 미치는 것으로 나타났으며, 골프장경기보조원의 경우 근무지 이외에 연령, 교육연수, 자녀수가 소득에 영향을 미치는 것으로 나타났다. The aim of this paper is to provide an overview of worker's in special employment's income level and states with an emphasis on determinants of their income. Because of the Supreme Court does not recognize workers in special employments as those defined as workers by the Labor Standard Act, 'Measures to apply industrial accident compensation insurance to workers in special employment' need to be come up with. The empirical analysis in this paper shows the followings: It is estimated that private accident insured, young, high-educated people result in higher income. But, several questions merit discussion. This paper lays the foundation for future works on improving policies of worker's in special employments.

여성친화적 사회적기업 발전에 관한 소고 : 지방자치단체의 여성인력개발센터 사례를 중심으로

조선주(Sunjoo Cho),김영옥(Youngock Kim) 한국여성정책연구원(구 한국여성개발원) 2008 여성연구 Vol.75 No.-

본 논문은 2000년대 이후 학계를 중심으로 사회적기업 연구가 활발해지면서 사회적기업이 한국사회에 양질의 일자리를 제공할 수 있는 대안으로 대두되기 시작됨에 따라, 여성친화적 사회적기업이 정부의 사회적 일자리 제공의 측면과 경제발전의 주요한 여성인적자원의 제공이라는 측면에서 중요하다는 인식 하에 수행되었다. 구체적으로 우리나라 사회적기업의 인증 현황을 소개하고, 주요 대상 지자체의 여성인력개발센터에 대해 문헌 및 홈페이지 조사와 사례분석을 통하여 사회적기업의 여성영역에서의 함의를 제공하고, 지속가능한 여성친화적 사회적기업으로서 발전할 수 있도록 연구의 기반을 제공하고자 하였다. 주요 연구결과 사회적기업의 인증은 서울 및 경기지역에 편중 분포된 것으로 나타났으며, 환경(20개, 18.5%), 간병·가사지원(17개, 15.7%)이 많은 업종유형을 차지하고 있었다. 사회복지를 주업종으로 하는 기관의 수가 꾸준하게 증가하고 있었으며 사회적 목적 실현은 일자리제공형이 가장 많은 것으로 나타났다. 그럼에도 불구하고, 사회적기업을 준비하거나 전망하고 있는 주요한 여성인력개발센터들은 사회적기업 인증에 대해 관망 중이며, 사회적기업 인증을 신청하고자 하 는 의지는 많으나, 인증요건들을 충족시키는 것에 매우 큰 부담을 느끼고 있는 것으로 나타났다. Since year 2000, researches on social enterprise centered on academia have been actively carried out and gave emergence to social enterprise as an alternative way to creating fine quality jobs in Korean society. Especially, female-friendly social enterprises can offer social employment of government and also encourage growth of female human capital which is important for economic development. This paper was carried out based on the recognition that understanding the concept of social enterprise should come before anything else. Therefore, this paper starts with the introduction of the current certification system of social enterprises. Then it provides the implication of female sector within the social enterprises by using documents, online research and case studies about Women Resources Development Centers in major local authorities. In addition, it aimed to offer the basis of research in order to develop a sustainable female-friendly social enterprise environment. Main research results showed that certification of social enterprise is concentrated in Seoul and the Gyeonggi-Do region. Majority of the enterprises are environment (20, 18.5%) and nursing and supporting housework (17, 15.7%). There is a constant increase in the numbers of organizations whose objective is to improve social welfare. The most notable achievement of social objective has taken place in the business field of job provisions. Nevertheless, the major Women Resource Development Centers preparing or prospecting for social enterprise are currently in observation of the certification of social enterprise. They have a strong willingness to apply for the certification but meeting the requirements of the certification is a huge burden for them.

Purpose: De novo malignancy is common after liver transplantation (LT); however, there are limited reports on the clinical outcomes of gastric cancer surgery after LT. Our study aimed to investigate the feasibility and safety of gastric cancer surgery after LT. Methods: Seventeen patients underwent gastric cancer surgery after LT at a single institution between January 2013 and June 2021. We retrospectively collected data on surgical complications, survival, and recurrence status of these cases. Results: Fifteen patients (88.2%) underwent curative gastrectomy, with 10 open distal (66.7%) and 5 laparoscopic distal (33.3%) gastrectomies. Surgical and severe complication rates were 3 of 15 (20.0%) and 1 of 15 (6.7%), respectively. There were no significant differences between laparoscopic (33.3%) and open surgery (66.7%) in terms of operation time and complication rate. No surgery-related mortalities occurred. Immunosuppressants could be maintained without difficulty, and no suspicious acute rejection was identified during the perioperative period. There was 1 recurrence after curative surgery (recurrence rate, 6.7%), and the 5-year cancer-specific survival rate after curative surgery was 93.3%. Conclusion: Laparoscopic gastrectomy can be safely done even after LT in terms of postoperative complications and graft safety.

The DTI additive in a blend of PTB7-Th donor and P(NDI2HD-T) acceptor enhances the power conversion efficiency of all-PSCs from 5.9 to 6.8%. Based on the analyses of the electrical, optical, and structural properties of all-PSCs, it is suggested that DTI additives promote tighter π–π packing and larger sizes of crystalline domains. Such morphological changes of the PTB7-Th:P(NDI2HD-T) blend films upon the addition of DTI enhance the exciton lifetime and diffusion length, which are proved by static and femtosecond-transient absorption spectroscopies and time-resolved photoluminescence. As a result of improved exciton dissociation probability and charge transport, the short-circuit current density of all-PSCs is greatly increased. Importantly, we also show that the DTI additive can be applied to other all-PSC systems with different polymer donors and naphthalene diimide (NDI)-based polymer acceptors, where the efficiencies of all-PSCs are enhanced by 10–20%.</P></▼2>

Microbial Population Dynamics and Temperature Changes during Fermentation of Kimjang Kimchi

Dongyun Lee,Sunjoo Kim,Jinhee Cho,김정호 한국미생물학회 2008 The journal of microbiology Vol.46 No.5

A distinct subset of lactic acid bacteria that are greatly influenced by temperature play an important role during kimchi fermentation. However, microbial population dynamics and temperature control during kimjang kimchi fermentation, which is traditionally fermented underground, are not known. Here we show that Lactobacillus sakei predominates in kimjang kimchi, perhaps due to suitable fermentation (5~9°C) and storage (-2°C) temperatures. The temperature of this kimchi gradually decreased to 3.2°C during the first 20 days of fermentation (-0.3oC/day) and then was stably maintained around 1.6°C, indicating that this simple approach is very efficient both for fermentation and storage. These findings provide important information towards the development of temperature controlling systems for kimchi fermentation.
