  • This research examined how pilots perceive risks when faced with emergency flight situations. We had 116 commercial airline pilots evaluate riskiness of 39 non-routine flight situations. The pilots' risk perception was analyzed as a function of their position (captain vs. first officer), expertise (expert vs. novice), and military flight experience (with vs. without military experience). Results showed that captains evaluated potential-risk situations and low-risk situations more dangerous than first officers. However, there were no differences between experts and novices, and between pilots having military flight experience and pilots not having military flight experience in risk perception. The analysis of multi-dimensional scaling revealed that the pilots used controllability as a key dimension for evaluating riskiness, though the other dimensions they used varied with their position, expertise, and military flight experience.

  • For the purpose of decreasing the chair time in implant cases, the time needed to loosening and fastening the screw must be shortened. Nowadays, the two typical designs of screw head are slot and hexa form. This study aimed at the shortening of loosening and fastening time by modifying the slot and hexa form. Total of twelve dentists participate in these experiments, four of them were experienced and eight of them were novice dentists. 1. There were many differences in the speeds of screw loosening and fastening between personal experiences. Experienced dentists are faster than novice dentists. 2. There were many differences in the speeds by angulation of the implant, by the conditions of the muscle tonicity. 3. Revised slot and hexa Heads show the slightly shortened time for acrew looseing and fastening.

  • This study intends to develop a fixture planning module as a part of the planning system for cutting. The fixture module uses machine learning method to reuse previous failure results so that the system can reduce the repeated failures. Machine learning is one of efforts to incorporate human reasoning ability into a computerized system. A human expert designs better than a novice does because he has a wide experience in a specific area. This study implements the machine learning algorithm to have a wide experience in the fixture planning area as a human expert does. When the fixture planner finds a setup failure for the suggested operations by a process planner, it makes the process planner store its attributes and other information for the failed setup. Then the process planner applies the learned knowledge when it meets a similar case so that the planner can reduce possibility of setup failure. Also the system can teach a novice user by showing a failed setup with a modified setup.

  • The purpose of this study was to apply the instruction consulting model for elementary science lesson with novice teacher. In this study the PIE(Preparation, Implementation and Evaluation stage) instruction consulting model was used. This model was introduced and offered during the electromagnet unit for sixth graders. The results of this study were as follows. First, in the assessment of the teacher's satisfaction with the instruction consulting the client teacher was found to be very satisfied. Second, the inquiry and scientific achievement for the students of the client's class were to increase in the experimental group, which demonstrated a statistically significant difference. Given the above results, the instruction consulting applied with the PIE model for novice teachers, who desire to raise the success rate of the experiment for students in the electromagnet unit of the elementary science class, helped the teachers to teach the students.

  • This paper investigates the three main functions of a typical visual app programming environment for Novice Programming developers, and compares the features. The Scratch is a visual programming environment for education, anyone can create a story easy as possible variously interaction, games, animations and more. App inventor provides precise and professional application development capabilities as compared with scratch. App Inventor in runs independently of the computer platform, and has a feature that must be constantly connected to the server over the internet, while the Inventor app runs. M-Bizmaker is suitable for commercial application development, consists of m-BizBuilder, m-BizEngine, m-BizServer or the like, provides a cross-platform visual programming environment.

  • The data in tables are accurate and rich in information, which facilitates the performance of information extraction and question answering (QA) tasks. TableQA, which is based on tables, solves problems by understanding the table structure and searching for answers to questions. In this paper, we introduce both novice and intermediate Korean TableQA tasks that involve deducing the answer to a question from structured tabular data and using it to build a question answering pair. To solve Korean TableQA tasks, we use S3-NET, which has shown a good performance in machine reading comprehension (MRC), and propose a method of converting structured tabular data into a record format suitable for MRC. Our experimental results show that the proposed method outperforms a baseline in both the novice task (exact match (EM) 96.48% and F1 97.06%) and intermediate task (EM 99.30% and F1 99.55%).

  • Objective: Identification of meaningful patterns and trends in large volumes of unstructured data is an important task in various research areas. In the present study, we gathered golf swing image data and did quantitative analysis of swing image. Method: We collected golf swing images of 30 novice players and 30 professional players in this study. Results: We selected important features of swing posture and employed data mining algorithm to classify whether a player is an expert or a novice. Moreover, our proposed method could offer quantitative advices for golf beginners for correcting their swing. Conclusion: Finally, we found a possibility that our proposed method can be expanded to golf swing correction system

  • A 30-year-old male novice golfer was diagnosed with a clay-shoveler's fracture. During golf practice, he experienced persistent posterior neck and upper back pain for a month. Cervical radiographs and computed tomography revealed a series of sequential spinous process fractures from C7 to T3. The patient was prescribed analgesic medication and fitted with a cervical brace alongside extracorporeal shockwave therapy (ESWT) directed explicitly toward the upper back region, subsequently leading to a notable reduction in pain. Therefore, ESWT could be considered an additional method for pain management in patients with clay-shoveler's fractures.

  • Since a variety of factors are associated with crash occurrence, the analysis of causes of crash is a hard task for traffic researchers and engineers. Among contributing factors leading to crash, the characteristics of driver is of keen interest. This study attempted to identify factors affecting the severity of pedestrian in the collision between pedestrian and vehicle. In particular, our analyses were focused on the novice driver. A binary logistic regression technique was adopted for the analyses. The results showed that driver's age, crash location, and the frequency of violations were dominant factors for the severity. Findings are expected to be useful information for deffective policy- and education-based countermeasures.

  • The purpose of this study is to analysis the horizontal distance of COM and COP and the movement patterns of COM and COP during the badminton high-clear of woman middle school student. The select variables used in the statistical analyses(independent sample T-test) were the horizontal distance of COM and COP at (E4), and the maximum COM displacement of the back-, forward-, whole-swing phases between expert and novice groups. Based on the results in this study, it was concluded that: First, expert group showed the shorter horizontal distance between COM and COP in anteroposterior axis (X-axis) at Event 4 compared to the novice group. Second, expert group dominantly used COM vertical movement while novice group actively used COM horizontal movement during the badminton high-clear stroke.
