This paper proposes a robot hand for a violin-playing robot and introduces a newly developed robot finger. The proposed robot hand acts as the left hand of the violin-playing robot system. The violin fingering plays an important role in determining the tone or sound when the violin is being played. Among the diverse types of violin fingering playing, it is not possible to produce vibrato with simple position control. Therefore, we newly designed a three-axis load cell for force control, which is mounted at the end of the robot finger. Noise is calculated through an analysis of the resistance difference across the strain gauge attached to the proposed three-axis load cell. In order to ensure the stability of the three-axis load cell by analyzing the stress distribution, the strain generated in the load cell is also verified through a finite element analysis. A sound rating quality system previously developed by the authors is used to compare and analyze the sound quality of the fourth-octave C-note played by a human violinist and the proposed robot finger.

Background: Progressive muscle weakness is aggravated not only in the skeletal muscles but also in the respiratory muscles in many patients with neuromuscular diseases (NMD). Inspiratory muscle training (IMT) has been reported as therapy for pulmonary rehabilitation to improve respiratory strength, endurance, exercise capacity, and quality of life, and to reduce dyspnea. Objects: The purpose of this study was to determine the effect of playing harmonica for 5 months on pulmonary function by assessing the force vital capacity (FVC), peak cough flow (PCF), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and maximal voluntary ventilation (MVV) in patients with NMD. Methods: Six subjects with NMD participated in this study. The subjects played harmonica once a week for 2 hours at a harmonica academy and twice a week for 1 hour at home. Thus, training was performed thrice a week for 23 weeks. The examiner assessed pulmonary function by measuring FVC in the sitting and supine positions and PCF, MIP, MEP, and MVV in the sitting position at the beginning of training and once a month for 5 months. Results: Both sitting and supine FVC significantly increased after playing harmonica (p=.042), as did MIP (p=.043) and MEP (p=.042). Conclusion: Playing harmonica can be used as an effective method to improve pulmonary function in patients with NMD.

The purposes of this study were to examine: (1) the extent to which school-age children used computer games; (2) whether there were differences between children who played computer games to a greater extent and children who played computer games to a normal extent in their levels of depression, anxiety, self-esteem, and social anxiety; and (3) whether children's social withdrawal, aggression, and mothers' psychological control explained the extent of children's computer game playing. The subject were 270 children in the 6th grade. It was found that $55.6\%$ of the children were normal users, $39.3\%$ of the children were somewhat heavy users, and $5.2\%$ of the children were heavy users of computer games. There was a gender difference in the proportions of heavy computer game playing. That is, there were more heavy users among boys than among girls. It was also found that social withdrawal, aggression, and mothers' psychological control were significant predictors of the extent of children's computer game playing. That is, the levels of children's social withdrawal, aggression, and their perceptions of mothers' psychological control predicted the degree to which children played computer games.

알고리즘의 추상적 속성은 학습자의 동기와 학습 증진을 저해하는 요소로 작용할 수 있다. 따라서 학습자의 내적 인지 부담을 감소시키고 동기를 유발하기 위한 교수 학습 방법에 관한 연구가 필요하다. 본 연구에서는 전문계 고등학생들의 동기와 성취수준 향상을 위해 놀이를 통한 알고리즘 교수 학습 프로그램을 개발하였다. 개발한 프로그램을 적용한 결과, 놀이 중심 알고리즘 학습 프로그램을 수행한 집단이 전통적인 알고리즘 학습을 수행한 집단에 비해 학습동기와 학업성취 면에서 유의한 차이를 나타냈다. 이는 놀이와 같은 구체적인 활동 수행이 추상적이고 어려운 개념 학습에 긍정적인 영향을 준 것으로 해석할 수 있다.

It is generally known that children's development of 'gender schema' and 'gender role stereotype' has a positive relationship with the notion of 'gender role preference'. This study analyzed an unusual case focusing on the role playing of two brothers'. The elder brother, Hyoung-Gyoo, always preferred to take the female role, and he had a preference for feminine names like "Cordelia" whilst engaging in role playing situations. The brothers can be said to have crossed the border into the realm of intersexual role playing. The results revealed Hyoung-Gyoo's clear discrepancy between gender-related perceptions and reality, and showed his younger sibling Je-Gyoo's high level of acceptance towards his brother's extraordinary gender role preference. The results of this study can serve as a useful reference point for detailing unusual development from early childhood regarding 'opposite-gender-role seeking' characteristics.

The purpose of this study is to investigate the children's different responses on the playground and facilities by the materials. For the study, the overall satisfaction on the playgrounds, the visiting frequency, the staying time, and olfactory and tactile responses were collected and analyzed by the materials. The materials for the playing facilities were categorized into 3 different groups ; steel, regular form wood and natural wood. The each group was also estimated and analyzed through the SD (sematic differential) scale which consisted of landscape adjectives. According the results, children liked and most highly scored the playground and playing facilities with natural wood in every items; overall satisfaction, visiting frequency, the staying time, and olfactory and tactile. On the other hand, the steel facilities were most negatively assessed in almost every items. Especially children felt the steel facilities were not environmentally friendly and very boring, comparing to the others. However, only 6 cases were analyzed in this study, because there were few playgrounds with natural wood facilities, so it is necessary to research on more cases to generalize these results.

Based on the love styles theory used in psychology, this paper classifies users(Passionate Love, Game-playing Love, Friendship Love, Practical Love, Possessive Love, Altruistic Love) and investigates satisfaction with the motivation for using TikTok love videos(Entertainment, Social Relationship, Love skills-learning, Self-verification, Problem-solving) according to the theory of use and satisfaction. First, 414 users were selected to conduct TikTok surveys to collect data. Then, through the analysis of the research results, among the six love types, game-playing type and possessive type have a positive (+) impact on entertainment motivation and love skill-learning motivation. Game-playing type also have a positive (+) impact on social relationship motivation and self-verification motivation. In addition, altruistic type and possessive type are also factors to strengthen the motivation of self-verification. The altruistic type, possessive type and practical type will improve the problem-solving motivation. Finally, through hierarchial multiple regression analysis, it is confirmed that game-playing love type, entertainment motivation, love skill-learning motivation and self-verification motivation can improve user satisfaction. The above results enrich the research of user classification as well as providing inspiration for improving the quality and communication efficiency of TikTok's video and enhancing user experience.
