연구논문 : 행복과 영성에 관한 사회학적 고찰: 한국 청년 세대연구를 향한 시론

오세일 ( Se Il Oh ) 아시아문화학술원 2015 인문사회 21 Vol.6 No.2

한국사회에서 행복에 대한 논의는 심리학계에서 주로 논의되어 왔다. 본 논문은 한국 사회에서 행복의 다차원적인 함의를 사회과학적으로 살펴보되 영성사회학의 관점에서 접근할 것이다. 본 논문은 신자유주의 체제의 노동 시장으로부터 강한 압박을 받으며 ‘실존적 불안’이 증대하고 있는 한국 사회의 청년 (대학생) 세대를 ‘사회실존적 취약층’으로 인식하고, 특히 대학생들의 행복과 영성에 관한 연구를 향한 시론의 성격을 담는다. 본 연구는 기존 문헌에서 행복에 영향을 미치는 제 요인들을 개인, 관계, 공동체, 사회구조 등의 다양한 차원에서 검토해 본다. 특히 대학생 세대의 행복에 영향을 미치는 중요한 요인들로 개인의 건강, 자기존중 (효능감), 소셜 네트웍크와 공동체, 학력 및 직업·성취의 기회구조, 사회적 질 등을 추출하게 된다. 그리고, 현대사회에서 영성의 함의를 검토하고 한국 대학생 세대에게 ‘영성’의 보편적 함의를 긍정심리학과 종교·영성사회학의 주된 관심인, 사회실존적 차원에서의 ‘삶의 의미와 가치’에서 찾는다. 끝으로 한국 대학생 세대의 행복 연구를 위해서 행복의 다차원성과 보편성, 역동성, 균형성을 전제로 하고, 영성 담론으로서 성찰성, 진정성, 상호관계성을 제안한다. Academic research on happiness has been accomplished mainly in the area of psychology. This article discusses the various implications of happiness from the perspective of the sociology of spirituality in the social sciences; however, it is a preliminary study of the generation of youth (university students) in Korea, regarding them as being ‘socio-existentially vulnerable’ under the pressure of labor market inthe neo-liberal regime. This study reviews empirically significant factors affecting on happiness at individual, relational, communal, socio-demograpic, and structural levels. In particular, this preliminary study finds individual health, self-respect (or efficacy), social network, community, education, and the opportunity structure of occupation or achievement, etc. as main factors affecting university students’ happiness in Korea. This study, then, finds the ‘meaning of life and values,’ in particular, as the universal implication of spirituality that is applicable to university students at a socio-existential dimension. In order to accelerate spiritual discourses on university students’ happiness, this study suggests three presuppositions about happiness such as 1) multi-dimension and commonality, 2) dynamics, and 3) balance, and the main factors of spiritual discourses such as 1) reflexivity, 2) authenticity, and 3) interdependence.

민간용 드론활용 연구

군사용으로 먼저 개발되어 시장을 형성했지만, 드론의 제작이 많아지면서 소비자 시장이 급속도로 확대되고 있다. 최근 중국의 DJI는 기업가치 100억 달러 이상을 넘볼 정도로 급성장 하였고, 드론용 소프트웨어나 플랫폼을 확보한 스타트업 기업들에 대한 투자도 활발하게 진행중이다. 구글이나 페이스북, 아마존 등 자사의 서비스 강화를 위한 목적으로 드론 기술을 적극적으로 활용하고 있으며, 드론의 시장 확대에 따른 드론 시장 생태계도 크게 확장하고 있다. 향후 민간용 드론 시대가 도래 할 것이라고 예상하고 있다. 이에 맞춰, 본 논문에서는 민간용 드론의 국내·외 활용사례 중심으로 살펴보고, 민간용 드론 시대를 대비하여 국내 대응 방안을 제시해보고자 한다.

보이스 포탈(Voice Portal) 서비스란 알고자 하는 정보를 음성으로 전화를 통해 명령하면 원하는 정보를 음성으로 서비스이다. 본 논문에서 구현된 시스템은 원하는 주식 정보를 음성으로 명령하면 Voice XML 서버가 찾고자 하는 주식 종목을 검색하여 다시 음성으로 알려주는 시스템이다. 인증의 절차를 수행하는 SMS (Short Message Service) 서버 모듈, PSTN망과 Database 서버사이의 인터페이스를 제공하는 CTI (Computer Telephony Integration) 모듈, CTI 서버와 WWW (World Wide Web) 사이의 Voice XML 모듈, 정보를 검색하기 위한 Searching 모듈들이 필요하다. 음성 인식 기술을 기반으로 한 CTI 모듈 설계를 구현하였다. 또한 인정 방식으로 Random한 일회용 패스워드를 기반으로 한 SMS 인증을 택하므로 더욱더 안정된 서비스 제공을 목적으로 하였다.

N/A Background : Heart transplantation is a definite treatment modality of the patients with end-stage heart failure. Heart transplantation has been performed in Korea since 1992, and currently it is an established procedure for the management of terminal heart failure. The purpose of this study is to clarify the Korean status of heart transplantation. Methods : Six major heart transplantation centers' 137 cases during the period November 1992 through May 1999 are analyzed to evaluate the general demographics, underlying heart diseases, postoperative management, complications, and survival. Results : The mean age of the patients is 37 years old, and the mean follow-up period is 25 months (1 day - 80 months, median 20 months). Most common underlying disease related to heart failure is cardiomyopathy (86%). Total 16% of patients underwent cellular rejection of ISHLT (International Society of Heart and Lung Transplantation) grade 3A or more within 1 year after transplantation. The most common type of clinical infection is bacterial (18%), and the most common organism is Herpes zoster virus (6.4%). Graft coronary artery disease examined by coronary angiography detected in 3.7% of recipients within 12 months after transplantation. One, 2, 3, and 5-year overall survival rates of recipients are 81% , 72%, 71%, and 62%, respectively. Conclusion : Distribution of underlying heart diseases and the frequency of graft coronary artery disease of Korean heart transplantation recipients were different from those of the western patients. Although the history of heart transplantation in Korea is relatively short, the early and long-term results are comparable with well-established centers.(Korean J Med 60:228-233, 2001)

The Courier Logistics Industry is expanding rapidly with the growth of e-commerce, and the competition is intensifying due to the existing logistics companies and newly participating non-logistic companies (distribution and E-commerce). Smart mobilities for courier delivery are Drones, Autonomous Vehicles, and Delivery Robots, and a combination of these services is emerging. In addition, core technologies of the 4th Industrial Revolution, such as advanced warehouse management using IoT and AI technologies, and logistics platforms using big data and cloud technologies, are expected to create new services by integrating into the parcelcourier delivery industry. Recently demand for lower prices and labor is growing due to the rapid growth of the parcelcourier delivery industry. This paper will propose the Last Mile Delivery improving method to replace labor and to improve profitability by using the core technology of the 4th Industrial Revolution, and expect the innovation of courier logistics industry through this.

Atrial fibrillation is the most common and most complex sustained arrhythmia. However, its pathophysiology has not been completely elucidated, therefore various approaches have been applied to its therapeutics. The management including pharmacological treatment is still evolving, and guidelines of atrial fibrillation have been updated frequently. This review article will introduce the principles and practical information on the pharmacological management in patients with atrial fibrillation based on the recently updated guidelines.

N/A Objectives: Percutaneous mitral commissurotomy (PMC) has been known as an effective palliative therapeutic modality for moderate to severe mitral stenosis, however, long-term changes of the mitral valve area and possible predictors affecting the long-term results after PMC has to be elucidated. Methods: 168 patients who were followed up at least 3 months (mean 18.7±13.9 months, range: 3-60 months) after PMC (double balloon technique) at Seoul National University Hospital between August 1988 and April 1993 (total 265 cases), were enrolled in the study. Mitral valve area (MVA) by pressure half-time method and the grade of mitral regurgitation (0-4) were evaluated by Doppler echo- cardiography at 1 day, 3, 6, 12, 24, 36, 48, and 60 months after PMC. The criteria of successful PMC were defined as mitral valve area ≥1.5cm² and mitral regurgitation with grade 2 or less. Results: Pre-PLIC mean MVA was 0.84±0.25 cm², immediate post-PMC MVA 1.64±0.49 cm², and mean MVA at the last follow-up was 1.54±0.43 cm. Relative MVA comparing to immediate post- PMC MVA at each follow-up time were 97.84±22.0, 96.5±24.9, 98.0±28.7, and 99.0±21.9% at 3, 6, 12, and 24 months after VMC, respectively. There were no significant differences between the groups with and without reduced MVA during follow-up period (defined as 15% or more reduction compared to that of immediate post-PMC). PMC resulted in increased grade of mitral regurgitation compared to that of pre-PMC (p=0.001), however, the severity of mitral regurgitation remained stationary in most patients during follow-up period. 86 patients (51.2%) remained in the criterior of successful results at long-term follow-up evaluation. Univariate analysis demonstrated that long-term successful PMC was related to sinus rhythm (p=0.002), low echocardio-graphic score (p=0.031, especially calcification, p=0.024), pre-PMC MVA (p<0.001), and immediate post-PMC MVA (p<0.001), but immediate post- PMC MVA was the only independent predictor of long-term successful PMC by multivariate analysis. Conclusion: Percutaneous mitral commissurotomy results in long-term relief of moderate to severe mitral stenosis in most patients, and the mitral valve area and the extent of mitral regurgitation remains stationary during long-term follow-up period.
