  • Cloud vehicular networks are a promising paradigm to improve vehicular through distributing computation tasks between remote clouds and local vehicular terminals. Software-Defined Network(SDN) can bring advantages to Intelligent Transportation System(ITS) through its ability to provide flexibility and programmability through a logically centralized controlled cluster that has a full comprehension of view of the network. However, as the SDN paradigm is currently studied in vehicular ad hoc networks(VANETs), adapting it to work on cloud-based vehicular network requires some changes to address particular computation features such as task computation of applications of cloud-based vehicular networks. There has been initial work on briging SDN concepts to vehicular networks to reduce the latency by using the fog computing technology, but most of these studies do not directly tackle the issue of task computation. This paper proposes a Software-Defined Cloud-based vehicular Network called SDCVN framework. In this framework, we study the effectiveness of task computation of applications of cloud-based vehicular networks with vehicular cloud and roadside edge cloud. Considering the edge cloud service migration due to the vehicle mobility, we present an efficient roadside cloud based controller entity scheme where the tasks are adaptively computed through vehicular cloud mode or roadside computing predictive trajectory decision mode. Simulation results show that our proposal demonstrates a stable and low route setup time in case of installing the forwarding rules of the routing applications because the source node needs to contact the controller once to setup the route.

  • Work related musculoskeletal disorders(WMSDs) was a leading cause of sick leave and injuries in the industries of our country. Posture was an important consideration in the design of work method and workplaces, because it affected the ability of workers to use various equipments and influenced how long they could perform their job without feeling discomfort, fatigue, and musculoskeletal disorders. Imbalanced lower limb postures such as a squatting posture were awkward working postures common to the shipbuilding shops, farms, automobiles assembly lines in our country. Different awkward working postures were known to be associated with specific musculoskeletal disorders. Eight postures in lower limb postures divided into balanced and imbalanced postures were evaluated by electromyographic(EMG) activity for lower limb muscles. Twelve male subjects participated in this study. This paper was to analyze the effects of lower limb muscles workload according to lower limb postures(knee angle) and working time. The ANOVA results showed that most EMG root mean square(RMS) values were statistically significant effect according to lower limb postures(knee angle) and working time. Therefore, the results of this study will provide the basis to evaluate workload of lower limb postures correctly adopted by workers in various jobs and the ergonomic reference to prevent WMSDs.

  • In most persons with disabilities had poor oral hygiene because of less attention and ability to perform a dental care. So the increased prevalence and severity of dental disease were common oral state. Although most persons with disabilities need a adequate dental treatment, it is often very difficult to treat because of noncooperativity and involuntary muscle movements. Dental treatments under sedation and general anesthesia were make to provide a high-quality dental service because of decreased anxiety and fear associated dental treatment in persons with disabilities. The dental professionals must be able to select and apply the proper sedation methods in agreement with the characteristics of the disabilities, general conditions, sedation experience and capacity of dentist, type and time of dental treatment, equipments of dental clinic, consent of patient's protector. The proshodontic treatment procedures, such as abutment preparation, dental impression taking process, try-in process of prosthesis and adjustment of occlusion, are difficult even for patients without disabilities. Those procedures are more difficult to patients with disability because it's too hard to control breathing and muscle. In this report, we performed prosthetic dentistry procedures to three patients with disabilities under dental sedation and general anesthesia.

  • Condition monitoring technologies allow achieving this goal by minimizing downtime through the integrated planning and scheduling of repairs indicated by condition monitoring techniques. Thermal runaways induced by conduction problems deteriorate insulating material and cause disruptive dielectric discharges resulting in arcing faults. Therefore, having the ability to directly measure the temperature of the contacts while in service will provide more information to determine the true condition of the equipment. It allows connective measures to be taken to prevent upcoming failure. Continuous temperature monitoring and event recording provides information on the energized equipment's response to normal and emergency conditions. On-line temperature monitoring helps to coordinate equipment specifications and ratings, determine the real limits of the monitored equipment and optimize facility operations. Using wireless technique eliminates any need for special cables and wires with lower installation costs if compared to other types of online condition monitoring equipment. In addition, wireless temperature monitoring works well under difficult conditions in strategically important locations. Wireless technology for on -line condition monitoring of energized equipment is applicable both as stand alone system and with an interface for power quality monitoring system. The paper presents the results of wireless temperature monitoring: of electrical equipment at a power plant.

  • Live Commerce is rapidly emerging as a new paradigm for the digital economy and consumption activities in the post-COVID era. Many prior studies have been conducted on Live Commerce, but studies focusing on the characteristics of sources of Live Commerce are insufficient. This study aimed to investigate the human factors of sources that affect consumers' intention to use Live Commerce. For this purpose, based on an expanded TAM (Technology Acceptance Model) through literature research, variables were set, and a survey was conducted targeting Korean consumers who have experienced purchasing products through Live Commerce. Excluding unreliable data, 201 responses were utilized in the analysis of this study. At first, the measurement tools were checked through validity and reliability verification, and correlation analysis was conducted to identify the relationships between variables. Then, the proposed hypotheses were verified through multiple regression analysis. As a result, firstly, the human factors of sources had a positive effect on PU (Perceived Usefulness). Secondly, the PEOU (perceived ease of use) had a positive effect on both PU and CS (Consumer Satisfaction). Thirdly, PU had a positive effect on CS and ITU (Intention to Use). Finally, CS with Live Commerce had a positive effect on the ITU. Through this study, we try to provide an understanding of consumer behavior in the Live Commerce environment and contribute to enhancing the service provider's ability to offer high-quality Live Commerce content.

  • 본 연구는 지적장애인은 의사소통능력이 부족하고 진술에의 진실성을 담보하기 어렵기 때문에 연구과정에 이들을 포함시키는데 소극적인 입장에서 탈피, 지적장애인의 적극적인 참여 패러다임으로의 변화를 강조한다. 이와 관련하여 '언어를 매개로 한 의사소통능력의 부족'은 지적장애인의 특성을 고려한 면접도구 개발과 대화분석방법을 도입함으로써, '진술의 진실성'에 대해서는 사회적 실재의 재현(representation)을 둘러싼 다양한 질적연구방법을 개발하고 진술 의미를 재구조화함으로써, 그리고 무지에 따른 배제와 억압의 메커니즘은 지적장애인의 삶 드러내기를 통해 극복될 수 있음을 보여주고 있다. 동 연구결과는 앞으로 장애정도별로 다양한 자료 수집 및 분석방법이 개발되어야 하며 아울러 각종 정부연구용역에서 지적장애인이 연구과정에 포함되도록 하는 연구방법론의 변혁이 필요하다는 함의를 제공해 준다.
