줄눈 콘크리트 포장에서 다웰바는 하중을 전달해주는 역할과 단차를 감소시켜줌으로써 궁극적으로 포장의 공용성을 높여주는 역할을 수행한다. 그러나 다엘바의 시공상태가 불량할 경우에는 오히려 줄눈잠김 등을 유발하여 스폴링이나 균열을 초래하여 공용성을 떨어뜨릴 수 있다. 다웰바의 시공방법은 다웰바 어셈블리 시공방법과 다웰바자동삽입기를 이용한 시공방법이 있는데 국내에서는 어셈블리를 이용한 시공방법만이 사용되고 있다. 본 연구에서는 비파괴 조사장비인 MIT-SCAN2를 이용하여 한국도로공사 시험도로에 시공된 다웰바자동삽입 시공구간과 다웰바 어셈블리 시공구간에 대한 다웰바 시공상태 및 Joint Score와 Running Ave. Joint Score를 산출하여 비교 분석해 보았다. 그 결과, 다웰바자동삽입 시공방법이 다웰바 어셈블리 시공방법에 비해 깊이변화, 수평/수직엇갈림에서 매우 우수한 시공상태를 보이는 것으로 나타났으며 줄눈잠김의 위험 또한 다웰바 어셈블리 시공방법에 비해 매우 낮다는 점을 발견했다. 또한 국내 다웰바 어셈블리 시공방법의 문제점을 다웰바 어셈블리의 생산, 보관, 시공 측면에서 분석하였다. 문제점 분석을 토대로 다웰바의 체어형태, 고정방법을 개선하여 시험시공을 수행한 결과, 모든 시공상태 항목이 개선되었음을 알 수 있었으며, 특히 수평/수직엇갈림이 크게 개선되어 줄눈잠김에 대한 위험성이 줄어듦을 알 수 있었다.

Examining how the CCP operated social services in Shanghai neighborhood[linong] in early 1950s, this article reveals the hidden relation between social service and rectification of neighborhood organizations in 1954. One of the main purpose of 1954 rectification was to guarantee provision of grassroots level of the city by recruiting local cadres, the implementers of social services. Though series of social service, such as night patrol, cleaning and public charity were indispensable for residents' life and welfare(fuli)[福利] of neighborhood, the social services was the something most of the Shanghai residents were reluctant to do. The result was the shortage of human resource for social service, triggering the "nominal position(gua ming)[掛名] " phenomenon. During political rectification of neighborhood organizations in 1954 Shanghai Municipal government tried to solve this 'decline of human resource in social services' problem by attracting the unemployed to the position of basic level cadre. To be specific, it demanded jobless person in neighborhood to be registered in time if they want a job placement. And it used that registration as the nominee of cadre in re-election process of the rectification campaign. The government measures were closely related to Shanghai people's inclination to rely on party-state when they try to get a job. Hence political rectification in neighborhood organizations become the strategic tool of city governance to mobilize residents in operating social services. So this article suggests that the CCP's urban governance was a complex and nuanced process to induce urban residents' interest and voluntarism beyond the suppression-oriented totalitarian perspective.

BIM-based Cloud platform gained popularity coupled with the convergence of Fourth Industrial Revolution technology. However, most of the previous work has not guaranteed sufficient efficiency to meet user requirements according to BIM service. Furthermore, the Cloud environment is only used as a server and it does not consider cloud characteristics. For the processing of High Capacity Data like BIM and using seamless BIM service, Resource management technology is required in the cloud environment. In this paper, to solve the problems, we propose a BIM platform for BaaS and an efficient resource allocation scheme. We also proved the efficiency of resource for the proposed scheme by using existing schemes. By doing this, the proposed scheme looks forward to accelerating the growth of the BaaS through improving the user experience and resource efficiency.

The number of unmanned light rail train operators is continuously increasing in Korea. In a failure event during an operation due to the nature of the unmanned operation, recovery is performed based on the remote control. However, if remote recovery is not feasible, safety personnel arrive at the train to resume the train operation. There are regulations on safety personnel and the suspension time of the train operation. However, there is currently no rule for safety personnel deployment. Currently, railway operating organizations operate in three scenarios: safety personnel on board trains, stationed at stations, and deployed at major stations. Four major factors influence the downtime for each emergency response scenario. However, these four influencing factors vary too much to predict results with simple calculations. In this study, four influencing factors were considered as random variables with high uncertainty. In addition, the Monte Carlo method was applied to each scenario for the safety personnel deployment to predict train service downtime. This study found a 17% difference in train service suspension by safety personnel deployment scenario. The results of this study can be used in setting service goals, such as standards for future safety personnel placement and frequency of service interruptions.

Cancer is a devastating disease, and the treatment of related pain is an extremely challenging task. Providing adequate analgesia while avoiding unnecessary drug effects often requires a polypharmacologic approach in cancer pain management. A 36-year old woman with breast cancer metastatic to the axial skeleton and bilateral hip joints was admitted to hemato-oncology service with complaints of intractable abdominal and hip pain. Despite rapidly increasing doses of intravenous morphine up to 350 mg per day; transdermal fentanyl; midazolam; ketorolac; lorazepam; dexamethasone, the patient continued to describe her pain as 10 of 10, refusing all surgical/diagnostic interventions not directly related to pain control. She did, however, consent to lumbar epidural catheter placement. The patient was sedated with titrating doses of propofol to assist with positioning. Even though the procedure was not successful due to significant thoracolumbar scoliosis, the patient admitted feeling better than she has in months during attempted placement. After continuous infusion of propofol was initiated at subhypnotic dose, the patient's analgesic demand was drastically reduced and described her pain as "1 to 3" of "10". Approximately 96 hours after the propofol infusion was started, the patient expired comfortably. There had been no change in her medical regimen during fecal 48 hours. In the case described, propofol was extremely advantageous as an adjuvant in the management of cancer related pain.

With the limited frequency spectrum and an increasing demand for cellular communication services, the problem of channel assignment becomes increasingly important. However, finding a conflict free channel assignment with the minimum channel span is NP hard. As demand for services has expanded in the cellular segment, sever innovations have been made in order to increase the utilization of bandwidth. The innovations are cellular concept, dynamic channel assignment and hierarchical network design. Hierarchical network design holds the public eye because of increasing demand and quality of service to mobile users. We consider the frequency assignment problem and the base station placement simultaneously. Our model takes the candidate locations emanating from this process and the cost of assigning a frequency, operating and maintaining equipment as an input. In addition, we know the avenue and demand as an assumption. We propose the network about the profit maximization. This study can apply to GSM(Global System for Mobile Communication) which has 70% portion in the world. Hierarchical network design using GA(Genetic Algorithm) is the first three-tier (Macro, Micro, Pico) model, We increase the reality through applying to EMC (Electromagnetic Compatibility Constraints). Computational experiments on 72 problem instances which have 15${\sim}$40 candidate locations demonstrate the computational viability of our procedure. The result of experiments increases the reality and covers more than 90% of the demand.
