Objective: This study was conducted for one-hand users including hemiplegic clients currently using general folding manual wheelchairs, so as to analyze their specific problems and recommend solutions regarding usage. Background: Traditional manual wheelchairs require considerable use and control of both hands for operation, thus adaptations become necessary for individuals with asymmetrical use of hands. Method: Thirty hemiplegic clients who were admitted to rehabilitation and convalescent hospitals participated as subjects. The research tools were general folding manual wheelchairs commonly used by people with impaired gait, and the Wheelchair Skills Tests (WST) WST-M/WCU 4.1 version was adopted as the assessment tool. All participants were asked to fill out questionnaires on demographics and wheelchair usage characteristics. Assessment procedures were performed with currently used manual wheelchairs and with/without the use of foot to control the wheelchair. Results: When the participants drove folding manual wheelchairs without the use of foot, even the lowest failure rate among the WST items tested recorded 96.7%. On the contrary, with the use of foot in maneuvering the wheelchairs, failure rates dropped noticeably and success rate among the WST items tested was as high as 86.7%. Conclusion: These findings imply that the use of one-arm (hand) propellable (drivable) wheelchair can be an active and effective solution in resolving problems for hemiplegic clients using existing manual wheelchairs. As such, the government should provide institutional support to further develop and distribute this device or technology, and promote relative research in tandem. For now, the supply of commercially available device to hemiplegic clients is deemed urgent and also a mechanism to provide the devices and relevant services. Application: This study offers viable solutions for hemiplegic clients who rely on existing manual wheelchairs to increase their mobility and occupational performance.

Background The reconstruction of volar surface defects is difficult because of the special histologic nature of the tissue involved. The plantar surface is the most homologous in shape and function and could be considered the most ideal of reconstructive options in select cases of volar surface defects. In this paper, we evaluate a single institutional case series of volar tissue defects managed with second toe plantar free flaps. Methods A single-institution retrospective review was performed on 12 cases of reconstruction using a second toe plantar free flap. The mean age was 33 years (range, 9 to 54 years) with a male-to-female ratio of 5-to-1. The predominant mechanism was crush injury (8 cases) followed by amputations (3 cases) and a single case of burn injury. Half of the indications (6 cases) were for soft-tissue defects with the other half for scar contracture. Results All of the flaps survived through the follow-up period. Sensory recovery was related to the time interval between injury and reconstruction-with delayed operations portending worse outcomes. There were no postoperative complications in this series. Conclusions Flexion contracture is the key functional deficit of volar tissue defects. The second toe plantar free flap is the singular flap whose histology most closely matches those of the original volar tissue. In our experience, this flap is the superior reconstructive option within the specific indications dictated by the defect size and location.

Purpose: Injuries are the most important cause of morbidity and mortality in the childhood population worldwide. Thus, this study was down to investigate the type and the severity of injuries according to the age group in childhood. Methods: A survey of injury information and a chart review were done on 378 children (257 boys, 121 girls) who visited the Emergency Departments of Asan Medical Center from March 1, 2009, to March 31, 2009. To determine differences in injury mechanism, accident place, injury site, New Injury Severity Score (NISS) and Pediatric Trauma Score (PTS), we divided the 378 patients into 4 group: under 1 year, 1 to 4 years, 5 to 9 years, and 10 to 15 years. Results: The mean (${\pm}SD$) age of the study group was 5.1 (${\pm}4.4$) years. Two year olds formed the largest group of injured children, with 77 cases (20.4% of the total). The most common cause of injury in childhood was being hit by an object (26.2%). Falls were frequent in the under-1-year group (22.2%) and slip downs (30.1%) were more frequent in 1-to-4-year group. More than half (53.4%) of the injuries occurred in the home, and the most common places of home-related injuries were the living room (41.1%) and the bedroom (31.2%). The mean (${\pm}SD$) NISS was 1.5 (${\pm}1.8$), and traffic accidents had the highest NISS ($2.8{\pm}5.1$). Injuries occurred most frequently during the evening. The peak period was 4:00 PM to 8:00 PM (33.7%). Conclusion: Patterns of childhood injury by age group were considerably different, and less severe and nonhospitalized injuries were common. Thus, need to improve surveillance of a variety of injuries, promote intersectional collaboration, build institutional capacities and mobilize community support and policy as an investment in prevention.

As a leading nation of ubiquitous technology, South Korea has been promoting u-City pilot projects throughout the country. According to 'Fundamental Construction Law of u-City,' u-City projects are classified into old-town and new-town types. However, most projects have focused only on the new-town type. Pushing forward large-scale land development projects, Korea Land and Housing Corporation (LH Co.) under Ministry of Land Transport and Maritime Affairs (MLTM) has gained a development profit out of the u-City infrastructure and then donated the infrastructure to a local government without making any plan for operations. In the process of u-City pilot projects, old-towns have been relatively ignored and various of unexpected problems have emerged. Building the u-City of an old-town is not easy due to many constraints such as huge initial investment, long validity and verification procedures, lack of useful services for citizens, lack of professional outsourcing methods for business promotion, high operating costs of the integrated control center, inadequate law related, insufficient institutional requirements and so on. This paper introduces a case study on u-City development for an old-town, Ansan City, as a private investment project. The case will help boost u-City projects for old-towns by solving their problems and providing an effective operational mechanism. As the first BTL (Build-Transfer-Lease) project for constructing u-City, 'Broadband Information Network Development Project' of Ansan City will provide a reference model of expanding u-City projects for other cities.

국가지리정보체계의 구축 및 활용 등에 관한 법률(구법/NGIS Act, 2000)이 폐지되고 국가공간정보에 관한 법률(신법/NSDI Act, 2009)이 제정되면서 국가 공간정보 정책 평가시스템에는 많은 변화가 발생되었다. 구법과 비교할 경우 신법은 국가 공간정보 정책의 추진체계가 일원화되었다는 장점은 있으나 예산 요구권의 약화로 공간정보 정책의 법적 실현가능성은 약화되었다는 논의가 있다. 이러한 문제의식 하에 구법에서 신법으로 법률이 새롭게 제 개정되면서 나타난 평가체계의 변화를 분석하는 것은 매우 중요한 의미를 갖는다고 할 것이다. 따라서 본 연구의 목적은 구법과 신법에서 규정한 국가공간정보 정책 평가체계를 비교 분석하여 평가 제도에서 나타난 변화가 무엇인지를 분석하는데 있다. 주된 연구방법은 구법과 신법의 비교분석 방법을 활용하였다. 비교 분석대상은 평가추진체계, 평가주체, 평가대상 및 범위, 평가결과의 활용, 평가전담기관 등이다. 분석결과를 토대로 할 경우 국가 공간정보 정책 평가시스템의 개선방안으로는 평가목적의 명확화, 평가 전담기관 제도의 활성화, 평가결과와 인센티브 및 예산 연계성의 강화, 공간정보정책의 사전 사후 연계성 강화 방법론 모색, 상향식과 하향식 접근이 결합된 평가지표의 개발 방안 등이 필요하다는 것을 제안하였다.

촛불의 분노는 부패한 박근혜 정부를 무너뜨리고 문재인 정부를 탄생시켰다. 촛불의 거시적 배경은 세계화와 신자유주의가 조성한 사회적 부조리와 불평등이며 촛불은 광범한 사회개혁과 복지국가를 요구한다. 문재인 정부가 촛불의 요구를 실현하려면 정치제도를 개혁해야 한다. 개혁의 핵심은 촛불의 요구를수용하는 것이며 이를 위해서는 비례대표제와 의회중심제가 절대적이다. 그러나 현실은 제도 개혁에 대해 수동적이고 미온적이다. 이런 점은 기득권 엘리트가 촛불이 웅변하는 변혁보다는 현상유지를 바라기 때문이다. 왜 비례대표제와 의회중심제가 민심을 반영하는가에 대한 지식과 정보가 광범위하게 확산되어야 한다. 학자는 정부형태와 사회적 요구 사이의 관계에 대해 논쟁하여 문제를 제기하고 미디어는 학문적 논의가 헌법개혁과 정치제도로 나타나도록 기여해야 한다. 비례대표제와 다당제 하에서 다양한 사회적 이해가 반영되며 이는 연합정부를 매개로 정책으로 실현된다. 중산층 정당과 진보정당은 보편복지를통해 연합정부에 참여하고 복지국가재정에 필요한 증세를 추진한다. 강력한정당기능에 기초한 의회중심제는 정당의 대표기능이 상대적으로 취약한 대통령제에 비해 강력한 사회정책을 제공한다.

Yeongdong has frequently suffered from severe snowstorms, which generally give rise to societal and economic damages to the region in winter. In order to understand its mechanism, there has been a long-term measurement campaign, based on the rawinsonde measurements for every snowfall event at Gangneung since 2014. The previous observations showed that a typical heavy snowfall is generally accompanied with northerly or northeasterly flow below the snow clouds, generated by cold air outbreak over the relatively warmer East Sea. An intensive and multi-institutional measurement campaign has been launched in 2019 mainly in collaboration with Gangwon Regional Office of Meteorology and National Institute of Meteorological Studies of Korean Meteorological Administration, with a special emphasis on winter snowfall and spring windstorm altogether. The experiment spanned largely from February to April with comprehensive measurements of frequent rawinsonde measurements at a super site (Gangneung) with continuous remote sensings of wind profiler, microwave radiometers and weather radar etc. Additional measurements were added to the campaign, such as aircraft dropsonde measurements and shipboard rawinsonde soundings. One of the fruitful outcomes is, so far, to identify a couple of cold air damming occurrences, featuring lowest temperature below 1 km, which hamper the convergence zone and snow clouds from penetrating inland, and eventually make it harder to forecast snowfall in terms of its location and timing. This kind of comprehensive observation campaign with continuous remote sensings and intensive additional measurement platforms should be conducted to understand various orographic precipitation in the complex terrain like Yeongdong.

Background: In Korea, the length of stay and medical expenses incurred by medical aid patients are increasing at a rate faster than the national health insurance. Therefore, there is a need to create a management strategy for each type of hospitalization to manage the length of stay of medical aid patients. Methods: The study used data from the 2019 National Health Insurance Claims. We analyzed the factors that affect the length of stay for 186,576 medical aid patients who were hospitalized for more than 31 days, with a focus on the type of hospitalization in long-term care hospitals. Results: The study found a significant correlation between gender, age, medical aid type, chronic disease ratio, long-term care hospital patient classification, and hospitalization type variables as factors that affect the length of hospital stay. The analysis of the differences in the length of stay for each type of hospitalization showed that the average length of stay is 291.4 days for type 1, 192.9 days for type 2, and 157.0 days for type 3, and that the difference is significant (p<0.0001). When type 3 was 0, type 1 significantly increased by 99.4 days, and type 2 by 36.6 days (p<0.0001). Conclusion: A model that can comprehensively view factors, such as provider factors and institutional factors, needs to be designed. In addition, to reduce long stays for medical aid patients, a mechanism to establish an early discharge plan should be prepared and concerns about underutilization should be simultaneously addressed.
