Changing Relationships between Education and Marriage among Korean Women

박현준,이재경,조인경 한국사회학회 2013 韓國社會學 Vol.47 No.3

Using the data from the 1-percent microdata sample of 2010 Census (N = 107,741), we examine changing relationships between education and first marriage across Korean women of three birth cohorts born in 1951-60, 1961-70, and 1971-80. We apply discrete-time hazard models to the person-year data, allowing the effect of women’s educational attainment on the risk of marriage to fully vary across cohorts and over duration. Women of younger cohorts have increasingly delayed and forgone marriage regardless of educational levels. However, the trend toward later and less marriage has been particularly significant among the lowest educated. In the result, for the youngest cohort, the percentage of women who remained single by the age 39 is highest at both ends of educational attainment. This contrasts the pattern among the oldest cohort where there was a linearly negative relationship between education and marriage, consistent with the findings in other East Asian countries.

Growing Up in a Single-Parent Family in Korea

박현준,주동범 (토론자) 한국직업능력개발원 2005 한국교육고용패널 학술대회 Vol.2005 No.1

한국 교육고용패널의 1차년도 자료를 이용해, 본 논문은 한국 사회에서 가족구조가 청소년들의 교육열망 (educational aspiration)과 학교 태도 (school disengagement)에 미치는 영향을 알아본다. 한부모가족 (single-parent families)의 상이함을 염두에 두고 네가지 유형의 한부모가족을 구분하여 (이혼으로 인한 편부가족, 사별로 인한 편부가족, 이혼으로 인 한 편모가족, 사별로 인한 편모가족) 그러한 가족구조에 있는 청소년들과 두부모가족 (two-biological-parent families)의 청소년들의 4년제 대학 열망 정도와 학교태도를 비교한다. 분석결과, 한부모가족구조의 부정적인 효과를 확인할 수 있었으며 특히 이혼으로 인한 한부모가족 구조의 부정적인 효과가 두드러진다. 사별보다는 이혼으로 인한 한부모가족 형성이 더욱 부정적인 효과를 가진다는 사실은 편부와 편모가족 모두에게서 발견된다. 이러한 한부모가족의 효과의 상당 부분은 한부모가족의 낮은 가구임금에서 기인하며 부모의 양육태도 역시 일정한 부분을 설명한다 (하지만 양육태도는 편모가족의 효과를 전혀 설명하지 못한다). 최근의 이혼율의 급속한 증가는 한국 사회에서 가족구조가 불평등의 중요한 기제가 될 수 있음을 시사한다.

본 연구는 뇌-머리 구조를3차원 모델로 제작하고 충격 시뮬레이션을 통해 뇌손상을 예측하기 위한연구이다. 뇌척수액(CSF)부분을 유체로 설정하고 ALE(Arbitrary Lagrangian-Eulerian)방식으로 해석할 수 있도록 3차원 모델을 제작하였으며, 머리에 충돌하는 질량체(Impactor) 속도를 조절하여 충격발생 시 발생하는 충격력을 기준으로 입력 값을 설정하였다. 여러 방향에서 충격을 주어 뇌에서 측정되는 최대압력 데이터로 뇌손상을 예측한다. Nahum.A는 머리 충격시험을 사체를 대상으로 실험을 하였으며, 시뮬레이션의 객관성을 확보하기 위하여 사체실험 데이터를 활용하였다. Nahum.A의 사체실험 방법을 시뮬레이션으로 모사하여 Nahum.A가 실험한 사체실험 데이터와 해석 결과값인 시뮬레이션 데이터 비교를 통해 모델의 타당성을 검증하였다. 충격 방향에 따라 뇌의 위치별(Front, Parietal, Occipital, Fossa)압력 분포가 달라지는 경향을 확인하여, 동일한 충격이 외부로부터 가해질 때 뇌손상에 가장 위협적인 충격 방향을 예측하는 연구를 수행하였다.

In-situ and highly sensitive detection of epidermal growth factor receptor mutation using nano-porous quartz crystal microbalance

박현준,유준석,박찬호,장규환,나성수 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.4

Assessment of epidermal growth factor receptor (EGFR) exon 19 mutations is very important indicator for treating lung cancer patients. In this report, we propose in-situ and highly sensitive detection method of EGFR mutation using quartz crystal microbalance (QCM) and nano-porous structured QCM electrode. The detection is based on the resonance frequency shift of QCM electrode upon DNA hybridization between probe DNA and EGFR mutant DNA (746–750 (del ELREA) in EGFR exon 19). Nano-porous structure is produced on the QCM electrode through simple processes of electrochemical deposition and etching. By using QCM, in-situ detection of EGFR mutation is performed within 30 mins. High sensitivity is achieved by introducing nano-porous structure on a QCM electrode, and the limit of detection (LOD) is 1 nM.

전립선비대증으로 인한 하부요로증상 환자의생약제제 이용현황: 단일기관연구

박현준,박남철,김현우,최상민,김창훈 대한남성과학회 2011 The World Journal of Men's Health Vol.29 No.1

Purpose: Recently, the use of complementary and alternative medicine (CAM) is increasing among patients with low urinary tract symtoms (LUTS) caused by benign prostate hyperplasia (BPH). We assessed current usage and awareness of phytotherapy, the most ubiquitous CAM, in BPH/LUTS patients. Materials and Methods: A total of 204 patients with BPH who completed a questionnaire between January 2009 and December 2010 were enrolled. The questionnaire was composed of questions about age, education level, accompanying disease, type of phytotherapy, route of purchase, reason of taking medicine and whether the patient is using phytotherapy in combination with conventional medicine. Results: The mean age was 55.5±8.7 years. 56 of the total patients (27.5%) were using phytotherapy. The patients who were accompanied with erectile dysfunction used phytotherapy the most. The most commonly used phytotherapy for prescription and health functional food was Saw palmetto. The most common route of purchase was by clinician's prescription (46.4%). Most patients answered the dissatisfaction of present treatment's effect as the main reason for using phytotherapy. The number of patients who were taking combination therapy of BPH medication and phytotherapy was much more than using phytotherapy alone. Conclusions: 27.5% of patients who had BPH/LUTS were using phytotherapy. This is the point of time for many urologists to acquire the knowledge of studies and latest research of phytotherapy and use it in treating patients with BPH/LUTS.

특발성 음낭석회증

박현준,남형종,최만수,최경운,박남철 대한남성과학회 2008 The World Journal of Men's Health Vol.26 No.2

Idiopathic scrotal calcinosis is a rare benign disease of scrotal skin, characterized by multiple asymptomatic nodules on the scrotum. The lesions are asymptomatic, round, firm, and yellowish nodules with variable size. Herein, we report a case of idiopathic scrotal calcinosis and a short review of the literature. A 42-year old man presented multiple painless, firm, nodules on his scrotum for about ten years. After excision of the nodules, mixture of calcified material was observed as a typical histological feature of idiopathic scrotal calcinosis.

Controlling Legal Risk for Effective Hospital Management

박현준,조덕영,박용석,김선욱,박재홍,박남철 대한남성과학회 2016 The World Journal of Men's Health Vol.34 No.1

Purpose: To analyze the types of medical malpractice, medical errors, and medical disputes in a university hospital for the proposal of countermeasures that maximize the efficiency of hospital management, medical departments, and healthcare providers.Materials and Methods: This study retrospectively reviewed and analyzed 55 closed civil lawsuits among 64 medical lawsuit cases carried out in Pusan National University Hospital from January 2000 to April 2013 using medical records, petitions, briefs, and data from the Medical Dispute Mediation Committee.Results: Of 55 civil lawsuits, men were the main plaintiffs in 31 cases (56.4%). The average period from medical malpractice to malpractice proceeding was 16.5 months (range, 1 month to 6.4 years), and the average period from malpractice proceeding to the disposition of a lawsuit was 21.7 months (range, 1 month to 4 years and 11 months).Conclusions: Hospitals can effectively manage their legal risks by implementing a systematic medical system, eliminating risk factors in administrative service, educating all hospital employees on preventative strategies, and improving customer service. Furthermore, efforts should be made to establish standard coping strategies to manage medical disputes and malpractice lawsuits, operate alternative dispute resolution methods including the Medical Dispute Mediation Committee, create a compliance support center, deploy a specialized workforce including improved legal services for employees, and specialize the management-level tasks of the hospital.
