  • Objective : This study compares Video laryngoscope and Direct laryngoscope in tracheal Intubation on rapidity and accuracy by paramedic and aims to improve efficiency of airway management and survival rate in pre-hospital treatment for the patients with severe trauma, cardiac arrest or dyspnea caused by acute diseases. Methods : 60 paramedics were recruited from 13 fire stations located in C province. With the consent of the paramedics, likelihood ratio test was carried out and they were divided into two different groups; DL group (30) and GVL group (30). Regarding intubation conditions, difficult airway grade I, grade II and grade III as well as sniffing position and neutral position were examined. This study also compared between ambulance in motion and in stand still. Frequency, average and standard deviation were analyzed with statistics program, SPSS WIN 17.0 and repeated measure design was introduced to examine inter-relations between position, grade and groups. Results : Intubation was performed more rapidly in neutral position and GVL than in sniffing position and DL(F = 15.260, p = .000). Rapidity value was better with grade I and grade II than grade III and better with GVL than DL(F = 32.629, p = .000). Accuracy value was higher with neutral position and GVL than sniffing position and DL(F = 5.008, p = .011). grade III was less accurate than grade I, grade II and GVL was more accurate than DL(F = 10.966, p = .000). Ambulance motion status did not show any statistically significant differences in accuracy and rapidity. Conclusion : Given this study results, neutral position is better for the patient with severe trauma. For a better survival, GVL intubation can be considered since GVL can enhance accuracy as well as rapidity regarding difficult airway. Since there is no significant differences in ambulance motion factors, intubation can be recommended even in moving ambulance for shortening traveling time to a hospital.

  • Rapidity and flexibility are very important in the electronic components industry. The laser process provides the industry with more rapidity and flexibility. For this reason, the laser process is considered as an acceptable method in terms of rapidity and flexibility. In this study, a wide range of experiments have been carried out on the gold wire-to-nickel thin film joining using the continuous wave fiber laser. In particular, changes in the shape of joint depending on the changes of a target point have been observed.

  • Rapidity and accuracy are important considerations when a drone is employed in a wide surveillance area to detect a target. They are more important when the scope of application is a search and rescue operation or the monitoring of natural disasters, which may require prompt warnings and response. During the actual operation of a drone, rapidity and accuracy are associated with the change in the altitude of the drone. The aim of this study is to analyze the characteristics of drones at varying altitudes and prove that altitude is a relevant factor in the performance of drones. Herein, the characteristics of the drone at varying altitudes were analyzed through several search simulations. The results suggest that a high-altitude drone is relatively advantageous compared to a low-altitude drone in a probability-based target search, and that the search altitude is also a very important and fundamental factor in target search by drones.

  • This study investigates the characteristics of local arbitration committees in China based on arbitration institution evaluation model. Most of the literature on Chinese arbitration committees only focuses on CIETAC. However, the promulgation of 1994 Chinese arbitration act allows local arbitration committees to deal the arbitration cases related with foreign element. Before 1994, only CIETAC and CMAC handle the arbitration cases related with foreign element. For the evaluation of the local arbitration committees, this study establishes the arbitration institution evaluation model. This model has seven evaluation criteria: accessability, independence, neutrality, rapidity, economy, professionality, and extent of enforcement. Our findings are as follows. First, Chinese local arbitration committees have the strengths in the fields of accessability, economy and rapidity. However, they are deficient in the area of neutrality, professionality, and independence. Second, the spatial distribution of Chinese local arbitration committees is not equal in China. The number of local arbitration committees is big in the high growth region such as Shandong province. On the other hand, the number of local arbitration committees is small in the economically stagnant area. Third, the size and activity of local arbitration committees are various. Some of them are very active in dispute resolution through arbitration in China. For example, Beijing Arbitration Committee(BAC), Wuhan, Quangzou Arbitration Committee play the important role in dispute resolution through arbitration. However, the large part of local arbitration committees is financially weak and depend on the local government's financial support.

  • This study analyzed the effects of smart phone using for business on work performance in the field. We classified functional and practical aspects of smart phone affecting employee's work performance through former studies. As independent variables, we selected portability of equipment, rapidity of information and ease of use for functional side, and selected fit to work and subjective norms for practical side. And dependent variable was work performance. We also suggested that innovation resistance would be a moderator. The results showed that the effect of work performance was influenced by portability of equipment and fit to work. However, hypotheses on moderating effects of innovation resistance were not supported. This study made a discrimination in terms of an application phase of smart phone as against former studies. The results of this study will provide practical implications for related enterprises in the field to develop ways of using smart phone as an effective strategy.
