주상현 ( Ju¸ Sanghyeon ) 한국자치행정학회 2021 한국자치행정학보 Vol.35 No.3

최근 한국사회는 인구감소에 따른 지역 공동화와 마을소멸에 대한 대응이 국가적 화두가 되고 있다. 이 연구는 인구소멸의 특성을 고찰하기 위해 전라북도 14개 기초자치단체의 인구소멸 실태를 빅데이터 분석과 인구학적 요인을 중심으로 살펴봄으로써 지방정부 인구 소멸의 문제를 해결을 위한 정책적 시사점을 제시하는 데 연구목적을 두고 있다. 이 연구의 연구방법은 전북지역 언론 기사를 중심으로 ‘BIGKinds’를 활용한 빅데이타 분석을 통해 인구소멸 경향을 분석하고, 14개 시군에 대해 소멸위험지수, 전입 및 전출 인구 추이, 주민등록 인구 추이, 빈집 수, GRDP, 제조업 사업체 수, 혼인 건수 및 혼인율, 재정자립도 및 재정자주도 등의 지표 추이를 분석하였다. 분석결과를 보면 첫째, 14개 시군 중 장수군과 김제시, 순창군, 무주군이 인구소멸과 관련하여 핵심이슈가 되는 지역이고, 인구소멸과 관련성이 높은 이슈는 고령화, 저출산, 지역경제, 일자리, 지역균형발전 등이 전북지역에서 다루어야 할 중요한 키워드들로 나타났다. 둘째, 전북지역 14개 시군 인구소멸 요인별 경향분석을 보면 시군별 소멸위험 지수는 전라북도 14개 시군 중 전주, 군산, 익산, 완주는 소멸 주의단계에 해당하고, 나머지 시군은 소멸위험 진입단계에 접어든 것으로 분석되었다. 셋째, 시계열적인 경향을 보면 전입인구 감소, 전출인구 증가, 빈집 증가, GRDP의 정체, 제조업사업체 수의 소폭 증가, 혼인 건수 및 혼인율 감소, 재정자립도 및 재정자주도 감소에 따른 지방정부 재정능력 약화가 주요 특징으로 나타났다. 분석결과를 토대로 이 연구는 첫째, 인구소멸과 관련하여 지역에 대한 특화된 연구를 통해 지역 맞춤형의 대응방안 등이 모색되어야 하며, 둘째, 인구소멸과 관련해서는 14개 시군 및 각 시군의 읍면동 지역을 구체적으로 분석하여 시군별 차별화된 대응전략을 강구하는 것이 필요하고, 셋째, 인구소멸과 연관성이 높은 다양한 지표들을 발굴하고 이들의 데이터를 추적하는 등 인구소멸에 대한 심층적인 분석이 수행되어야 하며, 넷째, 강력하고 종합적인 출산장려정책 시행, 지역균형발전 정책 수행을 통한 지역의 자립적 성장 추진, 지역활력 정책 수립 및 시행, 지방정부-지역대학-공공기관 간 협력적 거버넌스 강화 등의 정책적 시사점을 제시하였다. In recent years, responding to population extinction has become a national topic in Korea. The purpose of this study is to present policy implications for overcoming the population extinction of local governments by examining the actual conditions of population extinction in the 14 local governments in Jeollabuk-do, focusing on big data analysis and demographic factors. In this study, big data analysis using ‘BIGKinds’ and trends in 8 major population indicators(extinction risk index, moving-in and moving-out population trends, resident registration population trends, vacant houses, GRDP, number of manufacturing businesses, number of marriages and marriage rate, financial independence and financial independence) were analyzed. The analysis results are as follows. First, issues highly related to population extinction were aging, low fertility, regional economy, jobs, and balanced regional development. Second, it was analyzed that Jeonju, Gunsan, Iksan, and Wanju among the 14 cities and counties in Jeollabuk-do were in the stage of extinction warning, and the remaining cities and counties entered the stage of entering the extinction risk. Third, the characteristics of the time series trend are a decrease in the moving-in population, an increase in the moving-out population, an increase in vacant houses, a stagnant GRDP, a slight increase in the number of manufacturing businesses, a decrease in the number of marriages and marriage rates, and a weakening of financial independence and financial independence. The implications of the study are as follows. First, in order to respond to population extinction, a specialized response strategy for each city and county is required. Second, it is necessary to discover various indicators highly related to population extinction and perform an in-depth analysis on population extinction. Third, policies such as strong fertility promotion policies, promotion of regional self-reliance growth through the implementation of balanced regional development policies, establishment and implementation of regional vitality policies, and strengthening of cooperative governance between local governments, local universities, and public institutions are necessary.

Sanghyeon Lee,In Park,Min-Su Kim,In-Woo Kim,Sang-Jin Shin 대한견주관절의학회 2021 대한견주관절학회 학술대회논문집 Vol.2021 No.3

Introduction and Background To evaluate the clinical manifestations of patients who required revision surgeries at early and late periods after failed arthroscopic rotator cuff repair, and to identify clinical and radiological differences related to the timing of revision surgery. Material and Method Sixty patients who underwent revision surgery due to symptomatic failed rotator cuff repair after arthroscopic repair were included. Patients were divided into two groups: patients who underwent revision surgeries within 1 year postoperatively (21 patients, group I) and patients who underwent revision surgeries more than 1 year postoperatively (39 patients, group II). Clinical and radiological characteristics were compared between the two groups before primary and revision surgery. Results VAS for pain (5.9±1.9 in group I, 3.9±1.4 in group II, P<0.001) and Constant score (50.7±9.9 in group I, 60.4±8.9 in group II, P<0.001) at the time of revision surgery were significantly different between the two groups. In group II, isometric muscle strength of forward flexion (74.1±21.1 to 63.9±15.1, P=0.020) and external rotation (73.0±23.5 to 61.2±15.0, P=0.032) were significantly deteriorated after primary surgery, even with significant improvement of pain and shoulder function (VAS: 5.7±1.9 to 3.9±1.4, P<0.001; Constant score: 50.3±11.0 to 60.4±8.9, P<0.001). On postoperative MRI, re-tear at the tendon-bone interface occurred significantly more in group I (81.0%) than group II (51.3%, P=0.024). Incidence of full-thickness tear of the subscapularis tendon was significantly different between the two groups (42.9% in group I, 12.8% in group II, P=0.012). Conclusions Patients who had early revision surgeries had significantly worse clinical outcomes after primary surgery than patients who had late revision surgeries. Healing failure at the tendon-bone interface and re-tear combined with full-thickness tear of subscapularis tendon were related to early revision. Conversely, patients of the late revision group had muscle weakness that considerably impacted daily activities, even with improved pain and shoulder function.

Deterioration of mechanical properties by the curing of phenolic resin during fabrication of porous PSZ ceramics under high temperatures and high humidities

Sanghyeon Yoon 한양대학교 세라믹연구소 2012 Journal of Ceramic Processing Research Vol.13 No.5

Mechanical and microstructural analyses of partially stabilized zirconia (PSZ) ceramics maintained under high temperature and a high relative humidity were investigated to elucidate the relation between the curing of the phenolic resin as a binder and the deterioration of the ceramics. The PSZ powders containing the binder were exposed to the high humidity (85%, 50 ο C) and the high temperature (25%, 100 ο C) atmospheres for 1 h before compaction. The green densities of the specimens decreased from 3.54 g/cm3 to 3.45 g/cm3 and to 3.35 g/cm3 , respectively. The flexural strengths decreased about 3% and 8% compared to the specimen exposed to a lower humidity and temperature condition (25%, 50 ο C). Rough surfaces and some agglomerated particles with a large volume of voids and internal spaces were observed in the fracture surfaces of the green bodies. These agglomerates were generated by the curing of the phenolic resin with the formation of methylene bridges. The reaction occurred by the decomposition of hexamine as a curing agent in the high temperature and the high humidity atmospheres.

Object Detection System for the Blind with Voice Command and Guidance

Sanghyeon Lee,Moonsik Kang 대한전자공학회 2019 IEIE Transactions on Smart Processing & Computing Vol.8 No.5

As object recognition technology has developed recently, various technologies have been applied to autonomous vehicles, robots, and industrial facilities. However, the benefits of these technologies are not reaching the visually impaired, who need it the most. In this paper, we proposed an object detection system for the blind using deep learning technologies. We use voice recognition technology in order to know what objects a blind person wants, and then to find the objects via object recognition. Furthermore, a voice guidance technique is used to inform sightimpaired persons as to the location of objects. The object recognition deep learning model utilizes the Single Shot Multibox Detector (SSD) neural network architecture, and voice recognition is designed through speech-to-text (STT) technology. In addition, a voice announcement is synthesized using text-to-speech (TTS) to make it easier for the blind to get information about objects. The control system is based on the Arduino microprocessor. As a result, we implement an efficient object-detection system that helps the blind find objects in a specific space without help from others, and the system is analyzed through experiments to verify performance.

Review of outcomes of using lower ethanol concentration (83%) in percutaneous ultrasound-guided renal cyst sclerotherapy in dogs

Sanghyeon Yoon,Jungmin Kwak,Deokho Im,Hakyoung Yoon 대한수의학회 2023 Journal of Veterinary Science Vol.24 No.5

Background: Percutaneous renal cyst sclerotherapy (PRCS) as a treatment for renal cysts is usually performed with a high concentration of ethanol (≥ 90%). This study reviewed cases in which a lower concentration of ethanol (83%) was used for the procedure in dogs. Methods: Records of cases of renal cysts treated by sclerotherapy using 83% ethanol in dogs were reviewed. Outcomes of the treatment were evaluated by comparing volumes of renal cysts before the procedure and the volumes after treatment, using ultrasound images with the volume reduction rates classified as follows: < 50% of initial volume (failed); ≥ 50% but < 80% of initial volume (partial success); ≥ 80% but < 95% of initial volume (great success); ≥ 95% of initial volume (complete success). Results: Out of nine dog kidneys, renal cysts sclerotherapy with 83% ethanol achieved partial success in one kidney, great success in four, and complete success in the other four. No side effect was observed. The mean of the volume-reduction rates was 90.00 ± 11.00 while the minimum and maximum reduction rates were 65% and 100%, respectively. Conclusions: The lower ethanol concentration (83%) is good for disinfecting kidneys in PRCS.
