Graph databases have been developed to efficiently store and query graph data composed of vertices and edges to express relationships between objects. Since the query types of graph database show very different characteristics from traditional NoSQL databases, benchmarking tools suitable for graph databases to verify the performance of the graph database are needed. In this paper, we propose an efficient graph database benchmarking system that supports diversity in graph inputs and queries. The proposed system utilizes OrientDB to conduct benchmarking for graph databases. In order to support the diversity of input graphs and query graphs, we use LDBC that is an existing graph data generation tool. We demonstrate the feasibility and effectiveness of the proposed scheme through analysis of benchmarking results. As a result of performance evaluation, it has been shown that the proposed system can generate customizable synthetic graph data, and benchmarking can be performed based on the generated graph data.

This experimental study examines whether paralinguistic behavior is a deception cue in an interrogation. 92 college students participated in an experiment and were randomly assigned to two conditions. Participant were then asked to take the money or not to take the money according to the condition they were assigned. Then participants had a face-to-face interrogation. During the interrogation, participants' paralinguistic behavior was recorded and used for coding and analysis. Results reveal that participants' paralinguistic behaviors differ depending on question types and deceptive paralinguistic cues are speech speed and fillers for the closed critical question and response latency, response length, and fillers for the open critical question. These findings implicate that part of paralinguistic behavior could be a deception cue and thus these cues might be applicable to deception detection in real world criminal investigations.

The aim of this study was to develop a list of nursing competency for nurses' continuing education, and to propose a competency-based continuing education system according to nurses' clinical ladder. The definition of nursing competency was extracted by analyzing 10 studies. Also, the knowledge base of each nursing competency was confirmed through Carper and Chinn & Kramer's research. Nurses' clinical ladder and preliminary items of nursing competency behavior indicators were verified by seven experts for content validity. The results of this study were as follows; Nursing competencies were defined as 'evidence-based patient care', 'education and counseling', 'nursing management and leadership', 'law and ethics', 'professional value and development', 'research and policy development'. In addition, the validity of the 4 stages of clinical ladder and the 24 indicators of nursing competency were confirmed by experts. These findings suggest that the competency-based continuing education system according to the clinical ladder will be utilized as an effective human resource development strategy for improving the professionalism of nurses.

At present, in the field of design research, the systematic research on Without Thought design is still insufficient, and it is used in conjunction with the concept of Affordance. Therefore, based on Naoto Fukasawa's design ideas of 'Without Thought' and related unconscious theory, this study will define the concept of 'Without Thought design'. Briefly, Without Thought design is to enable users to complete the unconscious interaction with objects and give users a feeling of "just right". Besides, by reviewing Naoto Fukasawa's works, papers, speeches and related literature, this study derives five Without Thought design principles: continuity of behavior, clarity of semantics, commonality of cognition, design for living situations and design for natural needs. Then, the content this study could be an origin that be helpful to define the concept of Without Thought in a more systematic way, looking forward to serving as the basic data for the process development of Without Thought design.

Problem-Based Learning (PBL) is a student-centered pedagogy that integrates nursing knowledge, skills, and attitudes into clinical nursing practice. This pilot aims to apply a PBL module on preschoolers' growth and development in the nursing curriculum. This quantitative study was performed to develop a PBL module following Dick and Carye's program development process (planning, development, application, and evaluation phases), and to evaluate its effects using structured questionnaires among sophomore nursing students. These students formed teams of four or five people each and spent 40 minutes participating in the PBL module. Data were analyzed using descriptive statistics, t-tests, and content analysis. Metacognition level increased significantly. There was no significant difference in team efficacy between pre-test and post-test. Post-test learning satisfaction was high. Students reported obtaining knowledge and problem-solving ability with respect to preschoolers' growth and development and were satisfied with teamwork. This finding offers fundamental knowledge concerning the application of a PBL module in nursing curricula.
