Purpose: The purpose of this study was to compare the stroke risk factors between middle-aged and elderly people. Methods: The study used a retrospective and descriptive design with secondary data analysis. Data were abstracted from 450 medical records of stroke patients admitted a university hospital between July 1, 2005 and December 31, 2015. Results: The lifestyle risk factors for middle-aged stroke patients were smoking, alcohol, obesity, and lack of health examinations with follow-up care. The clinical risk factors for middle-aged stroke patients were high levels of alanine aminotransferase (ALT), total cholesterol, triglyceride, low density lipoprotein (LDL) cholesterol, and high systolic and diastolic blood pressure. The stroke triggers for ischemic stroke were uric acid for middle-aged patients and CRP for elders. Ischemic stroke among elders frequently occurred during periods of high daily temperatures. Conclusion: Findings indicate that for elderly patients, it is important to manage chronic diseases such as hypertension, diabetes, hyperlipidemia, and atrial fibrillation to prevent stroke. There are also sociocultural needs that are important to maintaining healthy life for these patients and should be addressed through targeted information. These study findings should be considered when developing prevention programs for Koreans at risk for stroke.

대학생이 지각한 부모-자녀관계와 진로결정수준 간의 관계에서 사회적 지지의 매개효과

석수진,김장회 한국교류분석상담학회 2018 교류분석상담연구 Vol.8 No.2

본 연구는 대학생의 부모-자녀관계와 진로결정수준 및 사회적 지지의 관계를 구조모형을 통해 살펴보고, 진로결정수준과 부모-자녀의 관계에서 사회적 지지의 매개효과를 확인하고자 시도되었다. 무선으로 표집 된 대학생 389명을 대상으로 조사한 자료를 분석한 결과, 대학생이 지각한 부모-자녀관계와 진로결정수준 및 사회적 지지의 세 변인은 모두 유의미한 관련성을 나타내었다. 한편, 아버지와의 관계는 사회적 지지와 진로결정에 영향을 주었고, 어머니와의 관계는 사회적 지지에만 영향을 주었다. 동시에 대학생이 지각한 부모-자녀관계와 진로결정 수준간의 관계에서 사회적 지지의 매개효과가 확인되었다. 이러한 결과를 토대로 대학생의 진로결정수준 증진을 위한 부모-자녀 간 긍정적인 관계 노력, 사회적 지지 차원의 개입 방안 등이 논의되었다. This study was conducted to explore the mediating effects of social support on the relationship between career decision making level and parent-child relationship based on the analysis of structural modeling. 389 survey conducted on college students. According to the analysis, the relationship among parent-child relationships, career decision level, and social support perceived by the university students showed significant results. Father-child relationship affected on the social support and the career decision level. Mother-child relationship affected on the social relationship only. Also, the mediated effect of social support was identified on the relationship between parent-child and career decision level. Based on the results, parent-child positive relationship efforts to enhance career decision level of college students, intervention strategies in terms of social support were discussed.

Production of NiO/N-doped carbon hybrid and its electrocatalytic performance for oxygen evolution reactions

석수진,장대운,김해주,박성진 한국탄소학회 2020 Carbon Letters Vol.30 No.5

Oxygen evolution reaction (OER) is an essential step at an anode in electrochemical water-splitting process and requires efcient electrocatalysts to reduce overpotentials. Although precious metal-based materials, such as RuO2, IrO2 and their hybrids with other components, performed excellently as OER electrocatalysts, their high cost has limited practical applica�tions. Consequently, earth-abundant metal components including Fe, Co, and Ni have been investigated as alternatives. In this work, the hybridization of Ni-containing species with conductive carbon-based materials was used to prevent aggregation of active species and improve electrochemical catalytic performance. A new hybrid material composed of NiO nanoparticles and N-doped carbon materials was prepared. The NiO particles with a narrow size distribution were well dispersed on the surface of carbon-based materials. The hybrid showed improved electrocatalytic performance for OER than single compo�nents of NiO and N-doped carbon materials.

보행 네트워크 활성화를 위한 도심부 오픈스페이스 연결성 분석

석수진,김승회 대한건축학회 2023 대한건축학회논문집 Vol.39 No.1

Since its self-declaration as a pedestrian-friendly city in 2013, Seoul has been conducting various pedestrian environment improvement projectsthroughout the downtown area. The ultimate goal of these efforts to improve the walking environment is to increase the quantity and qualityof walking in the city through the simultaneous installation of a public transport system and a pedestrian network. To encourage pedestrianwalking, the establishment of a network of external spaces linked with an open space was set as a guideline during the planning stage; thisurban environment maintenance zone was planned and developed in each zone. This study aims to analyze data focusing on the connectivityof open spaces in an urban environment maintenance area that prioritizes activating a pedestrian network. Open space is an auxiliary basethat enhances interaction between major bases; it is also a space where social activities occur, an everyday place located in the city centerand serves as a key factor in strengthening continuous and well-connected walking. To analyze open space connectivity, three networkconcepts were used: two-dimension, three-dimension and socio-Spatial. The results showed that two-dimension connectivity was high, whereasthree-dimension network and Socio-Spatial network connectivity was low. This was due to a Two-dimension formal plan being appliedwithout considering the purpose of the public space, which should be established based on contact amongst members of society. Based onour analytical findings, important factors for consideration was suggested when creating an external space for a pedestrian network in anurban environment improvement project to be carried out in the future. 2013년 보행친화도시 선포 이후 서울시는 10년간 도심부 전역에 다양한 보행환경개선 사업들을 진행해왔다. 이러한 보행환경 개선 시도와 노력의 궁극적인 목표는 도심부에 대중교통 활성화와 동시에 보행네트워크를 구축하여 도심부 보행의 양과 질을 높이는 것이다. 특히 구역단위로 계획, 개발되는 도시환경정비구역은 계획단계에서부터 보행활성화를 위해 오픈스페이스와 연계한 외부 공간의 네트워크 구축을 유도지침으로 설정하였고, 이를 바탕으로 사업이 진행되었다. 따라서 본 연구에서는 보행네트워크 활성화를 위한 도시환경정비구역 내의 오픈스페이스 연결성에 주목하여 분석을 진행하였다. 오픈스페이스는 주요 거점 간의 상호작용을 높이는 보조거점인 동시에 도심부에 위치한 일상적인 장소로서 사회적 활동이 일어나는 공간으로 보행의 지속적인 연결을 강화시키는 핵심적인 요소이다. 오픈스페이스의 연결성 분석은 평면, 입체, 사회-공간으로 구분된 세 가지의 네트워크 개념이 사용되었다. 분석 결과 평면적, 입체적 네트워크 연결성은 높은 반면, 사회-공간 네트워크의 연결성은 낮다고 분석되었다. 이는 사회 구성원들 간의 접촉을 기반으로 계획되어야 하는 공공공간의 목적에 관한 고려 없이 평면적이고 형태적인 계획이 적용되었기 때문이다. 결과적으로 본 연구는 도출된 분석결과를 통해 추후에 진행될 도시 환경 정비 사업시 보행 네트워크를 위한 외부 공간 조성에 고려요소를 제안하는 것에 의의가 있다.

The Time between Paraquat Ingestion and a Negative Dithionite Urine Test in an Independent Risk Factor for Death and Organ Failure in Acute Paraquat Intoxication

석수진,Young-hee Kim,길효욱,송호연,홍세용 대한의학회 2012 Journal of Korean medical science Vol.27 No.9

To identify a prognostic marker that is less sensitive to variations in the elapsed time since paraquat ingestion, we assessed the time between paraquat ingestion and a negative dithionite urine test as a prognostic parameter in patients with acute paraquat intoxication. Forty-one patients with acute paraquat intoxication were enrolled in this study and analyzed to verify significant determinants of mortality and organ dysfunction. The amount of paraquat ingested, paraquat plasma levels, and the time to a negative urine dithionite test were significant independent risk factors predicting mortality. The amount of paraquat ingestion, and the time to a negative urine dithionite test were independent risk factors predicting organ dysfunction. With a cut-off value of 34.5 hr for the time to negative conversion of the urine dithionite test, the sensitivity and specificity for mortality were 71.4% and 75.0%, respectively. The incidence of acute kidney injury and respiratory failure above 34.5 hr were 100% and 85.0%, respectively. In conclusion, the time to a negative urine dithionite test is the reliable marker for predicting mortality and/or essential organ failure in patients with acute paraquat intoxication, who survive 72 hr.

To investigate the effects of reactive oxygen species (ROS) on tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) plasma levels, and their possible implications on clinical outcome, we measured tPA and PAI-1 levels in 101 patients with acute paraquat (PQ) intoxication. The control group consisted of patients who ingested non-PQ pesticides during the same period. tPA and PAI-1 levels were higher in the PQ group than in the controls. PQ levels were significantly correlated with ingested amount,timelag to hospital, tPA level, and hospitalization duration. tPA levels were correlated with PAI-1, fibrin degradation product (FDP), and D-dimer. D-dimer levels were lower in the PQ group than in the controls. Univariate analysis indicated the following significant determinants of death: age, ingested amount, PQ level, timelag to hospital, serum creatinine, lipase, pH, pCO2, HCO3-, WBC, FDP, PAI-1, and tPA. However, multivariate analysis indicated that only PQ level was significant independent factor predicting death. In conclusion, tPA and PAI-1 levels were higher, while D-dimer levels were lower in the PQ group than in the controls, implying that ROS stimulate tPA and PAI-1, but PAI-1 activity overrides tPA activity in this setting. Decreased fibrinolytic activity appears to be one of the clinical characteristics of acute PQ intoxication.

석수진,최상천,길효욱,양종오,이은영,송호연,홍세용 대한의학회 2012 Journal of Korean medical science Vol.27 No.2

Chloracetanilide herbicides (alachlor, butachlor, metachlor) are used widely. Although there are much data about chronic low dose exposure to chloracetanilide in humans and animals, there are few data about acute chloracetanilide poisoning in humans. This study investigated the clinical feature of patients following acute oral exposure to chloracetanilide. We retrospectively reviewed the data on the patients who were admitted to two university hospitals from January 2006 to December 2010. Thirty-five patients were enrolled. Among them, 28, 5, and 2 cases of acute alachlor, metachlor, butachlor poisoning were included. The mean age was 49.8 ± 15.4 yr. The poison severity score (PSS)was 17 (48.6%), 10 (28.6%), 5 (14.3%), 2 (5.7%), and 1 (2.9%) patients with a PSS of 0,1, 2, 3, and 4, respectively. The age was higher for the symptomatic patients (1-4 PSS)than that for the asymptomatic patients (0 PSS) (43.6 ± 15.2 vs 55.7 ± 13.5). The arterial blood HCO3- was lower in the symptomatic patients (1-4 PSS) than that in the asymptomatic patients (0 PSS). Three patients were a comatous. One patient died 24 hr after the exposure. In conclusion, although chloracetanilide poisoning is usually of low toxicity, elder patients with central nervous system symptoms should be closely monitored and cared after oral exposure.
