Kodály hand signs are symbols that intuitively represent pitch and note names based on the shape and height of the hand. They are an excellent tool that can be easily expressed using the human body, making them highly engaging for children who are new to music. Traditional hand signs help beginners easily understand pitch and significantly aid in music learning and performance. However, Kodály hand signs have distinctive features, such as the ability to indicate key changes or chords using both hands and to clearly represent accidentals. These features enable the effective use of Kodály hand signs. In this paper, we aim to investigate the changes in recognition rates according to the complexity of scales by creating a device for learning Kodály hand signs, teaching simple Do-Re-Mi scales, and then gradually increasing the complexity of the scales and teaching complex scales and children's songs (such as "May Had A Little Lamb"). The learning device utilizes accelerometer and bending sensors. The accelerometer detects the tilt of the hand, while the bending sensor detects the degree of bending in the fingers. The utilized accelerometer is a 6-axis accelerometer that can also measure angular velocity, ensuring accurate data collection. The learning and performance evaluation of the Kodály learning device were conducted using Python.

Public bicycle system (PBS) is a new emerging and popular mode of public transportation. PBS data can be adopted to analyze human movement patterns. Previous work usually focused on specific scales, and the relationships between different levels of hierarchies are ignored. In this paper, we introduce a multi-scale and interactive visual analytics system to investigate human cycling movement and PBS usage condition. The system supports level-of-detail explorative analysis of spatio-temporal characteristics in PBS. Visual views are designed from global, regional and microcosmic scales. For the regional scale, a bicycle network is constructed to model PBS data, and an flow-based community detection algorithm is applied on the bicycle network to determine station clusters. In contrast to the previous used Louvain algorithm, our method avoids producing super-communities and generates better results. We provide two cases to demonstrate how our system can help analysts explore the overall cycling condition in the city and spatio-temporal aggregation of stations.

Objective : The purpose of the study was to investigate and compare the differences between Parkinson's disease rating, balance, fall and gait scales. Results : Parkinson's disease rating scales include the Hoehn-Yahr Scale and the Unified Parkinson's Disease Rating Scale (UPDRS). The Hoehn-Yahr Scale can measure disease rates easily; however it is not sensitive enough to evaluate the disease's process and management. UPDRS's advantage is in it's higher inter-reliability score; however it is more complicated to use. Parkinson's balance scales are comprised of the Berg Balance Scale (BBS) and the Activities-Specific Balance Confidence Scale (ABC). BBS has the advantage in that it is cheaper to measure and simple in use. ABC's advantage is especially in it's ability to measure higher functional levels; however it is more difficult measure responses due to scores appearing in both extremes. The Fall Efficacy Scale (FES) and The Survey of Activities and Fear of Falling in the Elderly (SAFE) are Parkinson's fall scales. FES's leverage over SAFE is that it is simpler to measure; however it does not coincide with responses which proves disadvantageous in measuring balance loss in high-level Parkinson's patients. SAFE's advantage is in it's simpler use and ability to be utilized without encountering the fear of fall; however it's at a disadvantage in regards to its use with multilateral aspects providing insufficient inspection. Lastly, the Dynamic Gait Index (DGI) and the Functional Gait Assessment (FGA) are Parkinson's gait scales. DGI is advantageous in its ability to test gait ability when exposed to a variety of external environments; however it is disadvantageous in that it registers higher scores with activities. FGA's advantage is in it's dynamic balance test; however it at a disadvantage with those unable to walk. Conclusion : A researcher of Parkinson's patients must choose each scale while considering their positive and negative characteristics.

This study examined the effects of employees' gender role attitudes, job involvement, and family involvement on their work-family conflicts, work-family facilitation, and utilization of family-friendly corporate policies. Data was collected from 377 full-time married workers from 262 large (more than 300 employees) and 100 small (fewer than 300 employees) private sector companies. The questionnaire's measurements were based on recommendations from the literature review. The questionnaire consisted of the gender role attitude scales, job and family involvement scales, work-family conflict and facilitation scales, and questions pertaining to the employee's utilization of family-friendly corporate policies. The SPSS 12.0 statistical package was used to analyze the collected data. The study found that employees showed more or less egalitarian gender role attitudes and that they were more involved in their family than their job. The employees' responses showed a low rate of utilizing family-friendly policies, but employees from large companies reported a higher utilization of family-friendly policies than those from small companies. There were also gender differences in employees' gender role attitudes, work and family involvement, and utilization of policies. Male workers held more traditional gender role attitudes, had higher levels of job involvement, and had higher rates of utilization of policies than female employees. Meanwhile, employees with children exhibited more traditional gender role attitudes and higher rates of utilization of policies than those without children. Finally, serial hierarchical regression analyses revealed that employees' more egalitarian gender role attitudes and higher job and family involvement predict higher work-family facilitation, while their gender role attitudes and job and family involvement have no significant influence on work-family conflicts. Also, employees from large companies with high job involvement will have significantly higher utilization rates of family-friendly corporate policies.

The study is to investigate mothers' parental beliefs about child development and the children's developmental tasks, and to explore the relationship between mother's parental beliefs and child-rearing behaviors. The subjects are 113 pairs of 4- to 5-year-old children and their mothers. For measuring maternal beliefs about child-development, 'beliefs about development scale' and 'child-rearing beliefs scales' were used. For mother's child-rearing behaviors, 'child rearing behavior observation scale' was used. The main results were: first, mothers value the cognitive theory and 'autonomous behavior' higher than 'conforming behavior' in developing their children. Second, there were no differences in mother's parenting beliefs in the factors of 'gender of their children' and 'maternal job status', while there were significant differences in maternal beliefs according to the levels of mother's education and family income. Third, sub-scales of their parenting beliefs were correlated with interactive behaviors between them and their children. The more mothers put importance on cognitive theory and children's autonomous behaviors, the more their supportive child-rearing behaviors during child-mother task solving situations were showed.

The purpose of this study was to explore the consumers' attitude and expectation-satisfaction on well-being products, Consumers' expectation, performance and disconfirmation scales were composed 7 items of 5-likert scales. Consumers' Satisfaction on well-being products was measured with one-item-measurement scale, The consumers' well-being attitudes were composed 4 dimensions such as (1)consuming the well-being products, (2)pursuit of mental well-being, (3)criticism about commercial fashion, (4) pursuit of harmony with natural life. The results were as follows: 1. The well-being attitudes were contrast with a positive attitude and negative attitude, Especially, criticism about commercial fashion was highly remarked. 2. There were statistic differences in the consumers' expectation and performance on well-being products, The Expectation was higher than the performance. It means that consumers' high expectation on the well-being products will bring about the lower satisfaction or dissatisfaction. 3. Consumers' Satisfaction on the well-being products was statistically different among groups by the well-being attitudes.

The purpose of this study was to analyze the trends, research methodology and findings of various researches on family resilience published in Korea over the past 13 years. A total of 93 publications related to family resilience between 1999 and June of 2012 were analyzed; 72 journal articles and 21 doctoral dissertations which had not been published in academic journals. The results are as follows; (1) There has been steady increase in the number of related researches since 1999, with a significant increase since the mid-2000s as various nontraditional families emerged and the perception of family problems began to change. (2) With regards to the methodology, the majority of the studies were empirical, using quantitative methods in both data collection and analysis. Most measurement scales employed were based on inventories developed by foreign researchers. (3) The research subjects encompass a wide range of individuals and groups from both vulnerable families and families from the general population. Additionally, some researches focused on special interest areas including program development & evaluation and scale development. Although research on family resilience has increased in quantity, there needs to be more qualitative, longitudinal and theory grounded studies on different families and individual types to better understand family resilience in depth. In addition, specific measurement scales reflecting the unique Korean family culture should be developed. Other challenges and suggestions for future research on family resilience are discussed.

Background: Previous research has suggested that single doses of a standardised Panax ginseng extract can decrease fasted blood-glucose levels and modulate cognitive performance in healthy young volunteers. The latter has generally been seen in terms of improved secondary memory performance. However, both the cognitive effects of chronic administration of ginseng and the potential modulation of working memory have received comparatively little research attention. Aims: The current double-blind, placebo-controlled, balanced cross-over study investigated the effects of 8-weeks administration of Korean ginseng extract (200 mg) on cognitive performance, gluco-regulatory parameters and ratings of subjective mood and 'quality of life'. Methods: 'Eighteen healthy young participants were assessed pre-dose and 3 hours post-dose on the mornings of Day 1, Day 29 and Day 57 of 8 week treatment regimens of both placebo and ginseng. A four-week placebo wash-out separated the treatment phases. Each assessment included the Cognitive Drug Research battery, computerised working memory tasks, and Bond-Lader mood scales. The WHO Quality of Life scale (WHOQOL-BREF) was completed once per visit. Gluco-regulatory parameters were assessed with assays of blood glucose, insulin and HbA1c. Results: Data from the 16 participants that completed the study showed that there were no significant, acute treatment related differences on Day 1 of treatment, or in gluco-regulatory parameters throughout the study. However, time related performance improvements were evident following chronic administration of ginseng on the '3-Back' and 'Corsi-block' computerised working memory tasks. Ginseng was also associated with an improved score on the 'social relations' subscale of the WHOQOL-100, and a significant shift on the 'calm' factor of the Bond-Lader mood scales (from calm/relaxed towards excited/tense). Conclusion: The results of the current study suggest that Korean ginseng extract can modulate working memory performance and subjective ratings of 'quality of life' and mood. Replication with a larger sample size may further elucidate the actions of this product.

Purpose: The purpose of this study is to evaluate the functional outcome and donor site morbidity of anterolateral thigh free flap(ALT) compared to Radial forearm free flap(RFFF) for the reconstruction of partial glossectomy defect. Methods: 5 ALT free flap (group I) were attempted for partial glossectomy patients. We compared patients undergone ALT flap with those(n=11) of similar size defect reconstructed with RFFF (Group II). Rating scales for articulation and swallowing function were applied and donor site morbidity have been evaluated. Results: The scales for speech function showed no difference between the two groups (average score; group I - 6.4, group II - 6.45). Swallowing function also showed no difference between the two groups(average score; Group I - 6.6, Group II - 6.27). ALT group had one patient with donor site morbidity(numbness). All of the RFFF patients(11/11) complained and suffered from hypertrophic scar, retraction, numbness or hyperpigmentation on forearm donor site. Based on our study, ALT free flap is comparable to that of RFFF in terms of functional assessment in tongue reconstruction. Conclusion: Considering the donor site morbidity, ALT flap is to be valuable to reconstruct partial glossectomy defect.
