장신재 서울장신대학교 출판부 2022 서울長神論壇 Vol.- No.30

본 연구의 목적은 우리나라 청소년의 스마트폰 의존과 학교적응 간의 관계에서 직업결정의 조절효과를 분석하는 데 있다. 이를 위해 2019년 한국청소년패널조사 데이터를 활용하였으며, 이 중에서 중1패널 2,590명을 최종 분석에 활용하였다. 본 연구의 주요한 분석결과는 다음과 같다. 첫째, 청소년의 스마트폰 의존이 심할수록 학교적응의 수준은 높아졌다. 둘째, 스마트폰 의존과 청소년의 학교적응 간의 관계에 있어 직업결정이 조절효과를 보이는 것으로 나타났다. 즉, 장래 직업결정이 높을수록 스마트폰 의존이 학교적응에 미치는 영향을 완화시키는 것으로 나타났다. 연구결과를 토대로, 청소년의 학교적응과 같은 가족관계의 질을 향상시키기 위한 주요한 요인으로서 직업결정 등과 같은 진로지도, 장래 계획 등에 대한 점검,관리 및 체계화가 요구됨을 제언하였다. The purpose of this study is to analyze the moderating effect of job decisions on the relationship between smartphone dependence and school adaptation among Korean adolescents. For this purpose, data from the 2019 Korean Youth Panel Survey were used, and among them, 2,590 middle school panelists were used for the final analysis. The main analysis results of this study are as follows. First, as adolescents' smartphone dependence increased, the level of school adaptation increased. Second, it was found that occupational decision had a moderating effect on the relationship between smartphone dependence and adolescents' school adaptation. In other words, it was found that the higher the future career decision, the less the influence of smartphone dependence on school adaptation. Based on the results of the study, it was suggested that the examination, management and systematization of career guidance and future plans such as career decisions are required as major factors to improve the quality of family relationships such as school adjustment.

장신이,김수진,이창관,조은정,조수진,이상철 대한심장학회 2016 Korean Circulation Journal Vol.46 No.4

Background and Objectives: Left ventricular diastolic dysfunction is known to be a marker of myocardial damage, in particular myocardial fibrosis resulting from hypertension (HT). However, few studies have shown an association between the grade of diastolic dysfunction and blood pressure classification. We investigated the association between diastolic dysfunction and prehypertension (preHT) in apparently healthy adults who underwent routine health examinations. Subjects and Methods: The study sample included 4261 Koreans, 45 to 64 years of age with no previous history of HT, diabetes mellitus, malignancy, proven coronary artery disease, or valvular heart disease based on echocardiography, who underwent routine health examinations including echocardiography. The subjects were classified into three groups based on resting blood pressure: prehypertensive, hypertensive, and normotensive. Results: The prevalence of preHT in our study was 42.1%. After adjusting for age, gender, smoking status, alcohol consumption, fasting blood sugar, serum lipid profile, and body mass index, left ventricular diastolic dysfunction grades 1 and 2 were significantly more frequent in subjects with preHT (odds ratio [OR] 1.66 [95% confidence interval {CI} 1.40-1.96] and 1.37 [95% CI 0.95-1.97], respectively). When analyzed according to gender, the increased OR was especially notable in males. Conclusion: Left ventricular diastolic dysfunction appears to be significantly associated with preHT in Korean middle-aged males.

장신이,주은영,허은희,Jung Hyun Kim,김덕경 대한의학회 2014 Journal of Korean medical science Vol.29 No.6

The aim of this study was to determine the normal value of brachial-ankle pulse wavevelocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group,gender, and the presence of cardiovascular risk factors in healthy Koreans, and toinvestigate the association between PWV and risk factors such as prehypertension,dyslipidemia, smoking, and obesity. We measured an arterial stiffness in 110 normalsubjects who were 20 to 69 yr-old with no evidence of cardiovascular disease,cerebrovascular accident or diabetes mellitus. The mean values of baPWV and cfPWV were12.6 ( ± 2.27) m/sec (13.1 ± 1.85 in men, 12.1 ± 2.51 in women; P = 0.019) and 8.70( ± 1.99) m/sec (9.34 ± 2.13 in men, 8.15 ± 1.69 in women; P = 0.001), respectively. Thedistribution of baPWV (P < 0.001) and cfPWV (P = 0.006) by age group and gendershowed an increase in the mean value with age. Men had higher baPWV and cfPWV thanwomen (P < 0.001). There was a difference in baPWV and cfPWV by age group onprehypertension, dyslipidemia, current smoking, or obesity (P < 0.001). In multiple linearregression, age and prehypertension were highly associated with baPWV and cfPWV afteradjustment for confounding factors (P < 0.001). The present study showed that baPWVand cfPWV are associated with age, gender, and prehypertension in healthy Koreans.

장신이,주은영,조성일,이승욱,김덕경 대한심장학회 2013 Korean Circulation Journal Vol.43 No.5

Background and Objectives: The objective of this study was to analyze and compare risk factors for peripheral artery disease (PAD) and coronary artery disease (CAD). Subjects and Methods: The sample included 7936 Korean patients aged ≥20 years who were hospitalized from 1994 to 2004. Of the 7936 subjects, PAD (n=415), CAD (n=3686), and normal controls (Control) (n=3835) were examined at the Health Promotion Center, Sam-sung Medical Center. Results: The mean age (years) of PAD subjects was 64.4 (±9.3), while CAD subjects was 61.2 (±9.9), and Control subjects was 59.9 (±9.1)(p<0.01). The proportion of males was 90.6% for PAD, 71.4% for CAD, and 75.5% for Control subjects (p<0.01). The adjusted odds ratios (ORs) for hypertension, diabetes mellitus, hypercholesterolemia, smoking, metabolic syndrome and chronic kidney disease were significantly higher in subjects with PAD or CAD compared to those in Control. However, the ORs for high density lipoprotein, being overweight, and be-ing obese were significantly lower in PAD subjects compared to those in Control. Conclusion: We found that cardiovascular risk factors were in fact risk factors for both PAD and CAD.

노인의 가족관계가 문제음주를 매개로 하여 생활만족도에 미치는 영향

장신재 서울장신대학교 2019 서울長神論壇 Vol.27 No.-

본 연구는 노인의 가족관계가 문제음주를 매개로 하여 생활만족도에 미치는 영향을 확인하고, 가족관계가 생활만족도에 미치는 효과를 보다 구체적으로 검증함으로써 실천적인 함의를 제시하고자 한다. 2017년 한국은 2000년 고령화 사회 진입 후 65세 이상의 노인 인구가 전체 인구의 14.3%로 17년만에 고령사회로 초고속 진입하였다(통계청, 2018). 고령화 사회에서 고령사회로 진입하는 데 24년이 걸린 일본과 비교하여도 유례없는 고령화 속도를 보이고 있다. 2026년 경에는 전체 인구의 20.8%로 초고령 사회에 도달할 것으로 전망된다(보건복지부, 2018). 고령화로 인한 노인 인구의 증가는 가장 큰 사회적 문제로 인식되고 있으며, 이와 관련하여 건강한 노후에 대한 관심이 그 어느 때보다 증대되고 있다(장신재, 2017).

장신이,서수라,박승우,김덕경 대한의학회 2017 Journal of Korean medical science Vol.32 No.4

The aim of this study was to assess the prevalence of Marfan syndrome (MFS) in Korean adults. Data were collected from the National Health Insurance Service in Korea from 2006 through 2013. The data consisted of primary diagnoses related to MFS (Q87.4) diagnosed according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems. The age-standardized prevalence of MFS in adults was calculated using the estimated Korean population in 2010 as a reference. Overall, the prevalence of MFS was 0.90 per 100,000 persons in 2006 and 2.27 in 2013. For males in 2013, the prevalence per 100,000 persons was 2.61 in overall and 4.32 in 15–19 years-old. For females in 2013, the prevalence per 100,000 persons was 1.92 in overall and 3.02 in 10–14 years-old. In conclusion, currently, the age-standardized overall prevalence of MFS was 2.27 persons per 100,000 persons. And the overall age-standardized prevalence of MFS increased between 2006 and 2013 especially in 15–19 years-old males and 10–14 years-old females.

장신이,주은영,조성일,이승욱,김덕경 한국자료분석학회 2011 Journal of the Korean Data Analysis Society Vol.13 No.4

The aim of this study was to investigate the risk for metabolic syndrome (MetS) in subjects with a positive family history (FHx) of hypertension/cerebrovascular accident, cardiovascular disease, and/or type 2 diabetes mellitus. The sample population included 5,742 Korean men and women aged ≥20 years. A numeric score of 1 was assigned to study subjects with positive FHx. The MetS group showed a higher score for FHx of cardiovascular risk factors (FHx scores). After adjusting for age, gender, and socioeconomic position, the odds ratio of MetS classification varied by FHx score: 1.47 (95% CI 1.27- 1.71), 1.54 (95% CI 1.13-2.09) and 3.98 (95% CI 1.33-11.9) for FHx scores 1, 2, and 3, respectively. This study suggests that subjects with higher FHx cardiovascular disease scores have a higher risk for MetS.

중국 커뮤니티 서비스 센터의 공간요소에 대한 사용자 인식 연구

장신이,한태권 한국공간디자인학회 2023 한국공간디자인학회논문집 Vol.18 No.3

(Background and Purpose) In modern Chinese society, urbanization has progressed rapidly due to the increase in the level of economic development and rapid industrialization. Economic and social development brought about major changes in the living environment and industrial structure, and material abundance caused various social problems in cities due to space consisting of relationships and spaces between people. The purpose of this study is to empirically analyze the space components and satisfaction of users visiting community service centers in China's first-line urban areas and give implications to these spatial design and operators to plan the space inside the community service center according to the characteristics and types of users. (Method) the purpose and motivation of users visiting the service center were analyzed based on preceding research, and metrics to classify user type and space composition were derived through research on user satisfaction. In addition, preceding research related to the definition and characteristics of the community service center were utilized and identified, the analysis of the interior design elements of spaces expanded the scope of research, and metrics for the spatial elements inside the community service center were derived. As an empirical research method, a survey on Tianjin and Shanghai community service centers and local residents was conducted on the users who visited the place from mid-October to the end of October 2022 and analyzed after the data were collected. SPSS Statistic Version 20.0 was used for the collected data, and the analysis on the importance and satisfaction was conducted by applying the IPA (Importance-Performance Analysis) method. (Conclusion) The study found that intensive management was needed due to its high importance but low satisfaction. In terms of comfort element, it includes exhibition rooms, Danggeon activity rooms, auditoriums, calligraphy classes, elderly and infant facilities, and cooking rooms. With regard to the element of functionality, it contains information desks, and educational activity rooms. comprehensive management rooms, work rooms, waiting rooms, and comprehensive art activity rooms were found. And in terms of accessibility, social welfare centers, health spaces were found. Finally, in terms of safety, residential committees, bath rooms, conference rooms, and complex culture centers were found to be the spaces that needed intensive management. Based on the research results, I would like to propose an improvement plan for the Chinese community service center as follows. In the case of China, since it is necessary to handle party-related tasks within the community center, it is desirable to consider design elements that care for the socially disadvantaged and eliminate inconvenience in using administrative tasks, including party tasks. In particular, administrative affairs related to the affairs of the party should be handled quickly, administrative services and information sharing for the convenience of residents through the establishment of various systems, and prompt feedback response. Spaces, such as fitness spaces, swimming pools, table tennis rooms, and tennis rooms, should be kept open in a location that is easy to access by various residents and should enable mutual communication. In other words, it is necessary to induce accessibility between various exercise spaces so that smoother mutual communication can be formed based on the positive experiences of residents of exercise.
