  • The significant reason for studying computer science lies in the efficient resolution of various problems which can arise in actual life. Consequently, algorithm education is very important in the computer science and plays a great part in helping to enhance the creative ability to solve problems and to improve the programming ability. However, the current algorithm education at an computer science educational institute for the gifted has inadequate systematic quality and is only treated as a part of programming education. From this perspective, this paper carried out following studies in order to design the algorithm education for elementary computer science prodigies. First, the core educational contents was selected by extracting the common elements from existing books related to algorithm education, common study contents on algorithm lesson websites and the study area of ACM's computer algorithm. Second, using the development criteria and selected educational contents, the educational theme for the If weeks load was set. Additionally, the algorithm educational contents were designed for the elementary computer science prodigy based on such theme. Third, the activity site for the use of prodigy educational institute was developed with the background in the educational contents for the elementary computer science prodigy. Fourth, the Delphi analysis technique was used to verify the appropriateness of contents and activity site developed in this paper. It was carried out in 2 separate processes where the first process verified the design of educational contents, and the second process verified the appropriateness of developed activity site.

  • The main purpose of this research was to examine the EMG characteristics of driver's upper limb and driving performance for operating accelerator and brake pedal by using four types of left hand control devices(Push/Pull, Push/Right angle, Push/Rock, Push/Twist) during simulated driving. The persons with disabilities in the lower extremity have problems in operation of the vehicle because of functional impairments for controlling accelerator and brake pedal. Therefore, if hand control device is used for adaptive driving controls in persons with lower extremity loss, the disabled people could improve their quality of mobility life by driving a car. Twenty subjects were involved in this research to assess driving performance and EMG activities for operating accelerator and brake pedal by using four types of left hand controls in driving simulator. We measured EMG responses of six muscles(posterior deltoid, middle deltoid, biceps, triceps, extensor carpi radialis, and flexor carpi radialis) during pulling and pushing movement with four types of left hand controls for acceleration and braking. STISim Drive 3 program was used for evaluation test of four types of left hand control devices in straight lane course for time to reach target speed and brake reaction time. While operating the four types of left hand controls for acceleration, EMG activities of posterior deltoid in normal subjects were significantly increased(p < 0.05) compared to the disabled subjects. It was also found that EMG responses of triceps and posterior deltoid were significantly increased(p < 0.05) when using the Push/Right angle type than Push/Pull type. While operating the four types of left hand controls for braking, EMG activities of flexor carpi radialis and triceps in subjects with disability were significantly increased(p < 0.05) compared to the normal subjects. It was shown that muscle responses of posterior deltoid, middle deltoid and triceps were significantly increased when using the Push/Right angle type than Push/Rock type. Time to reach target speed and brake reaction time in subjects with disability was increased by 2.5% and 4.6% on average compared to normal subjects. The person with disabilities showed a tendency to relatively slow performance in acceleration at the straight lane course.

  • The purpose of this study is to look at the way that speech-to-text (STT) services are used at present, and to explore measures to institutionalize such services for ease of communication for the hearing impaired. The results of this study show the following: 1) 17.8% of those surveyed had experience of using STT services, with younger individuals showing a higher rate of use; and 2) In terms of organizations providing STT services, social welfare organizations followed by civic groups (18.3%) and public organizations (18.3%). The following institutional measures are needed for STT services. First, STT services should be actively promoted as one of the reasonable conveniences defined in the 'Act on the Prohibition of Discrimination Against Disabled Persons, Remedy Against Infringement of Their Rights, etc.' Second, STT services should be additionally listed as one of the clauses of the 'Act on Welfare of Persons with Disabilities'. In particular, establishing a communication system for those with hearing impairments should serve as a catalyst for integration with sign language interpretation and welfare services. If STT services for face-to-face contacts can be improved or further enhanced using ICT, it will not only open the way for a new influx of disabled workers to join vocational rehabilitation, but also help to improve quality of life for the hearing impaired.

  • Poultry industry is abounding day by day as it engrosses less cost of investment per bird as compared to large animals. Poultry have the most copious genomic tool box amongst domestic animals for the detection of quantitative trait loci (QTL) and marker assisted selection (MAS). Use of multiple markers and least square techniques for mapping of QTL affecting quality and production traits in poultry is in vogue. Examples of genetic tests that are available to or used in industry programs are documented and classified into causative mutations (direct markers), linked markers in population-wide linkage disequilibrium (LD) with the QTL (LD markers), and linked markers in population wide equilibrium with the QTL (LE markers). Development of genome-wide SNP assays, role of 42 K, 60 K (Illumina) and 600 K (Affymetrix$^{(R)}$ Axim$^{(R)}$) SNP chip with next generation sequencing for identification of single nucleotide polymorphism (SNP) has been documented. Hybridization based, PCR based, DNA chip and sequencing based are the major segments of DNA markers which help in conducting of MAS in poultry. Economic index-marker assisted selection (EI-MAS) provides platform for simultaneous selection for production traits while giving due weightage to their marginal economic values by calculating predicted breeding value, using information on DNA markers which are normally associated with relevant QTL. Understanding of linkage equilibrium, linkage dis-equilibrium, relation between the markers and gene of interest are quite important for success of MAS. This kind of selection is the most useful tool in enhancing disease resistance by identifying candidate genes to improve the immune response. The application of marker assisted selection in selection procedures would help in improvement of economic traits in poultry.

  • Objectives: This study was conducted to analyze the general properties of beauticians and to analyze correlation between their experiences of indigestion and relevant factors and thus to provide basic data to prevent obstacles to beautician's health. Methods: A self-administered survey on 257 female beauticians in Daegu from March 15 to May 30, 2005 was conducted. Cross-link analysis was used to examine indigestion in relation to the general properties of beauticians, and correlation analysis was used to determine the level of relationship between indigestion and relevant factors, and multiple regression analysis was used to determine the degree of effects of relevant factors on indigestion. Results: The results can be summarized as follows: 1. As for indigestion by general properties and beauty-related properties, there were significant differences in gender(p<0.01), age(p<0.05) and marriage status(p<0.05) among general properties and there were significant differences in the number of holiday(p<0.05), beauty culture career(p<0.01), and the degree of satisfaction on duty(p<0.001) among beauty-related properties. As for indigestion by eating habit and health-related properties, there were significant differences in the degrees of regular eating(p<0.001) and regular living habit(p<0.001), and eating speed(p<0.01). 2. Factors relevant to the eating habit showing significant correlation with indigestion were regular eating habit, taking well-balanced nutrition, and taking salty food. Among them, the regular eating habit was shown to be the most relevant with the correlation coefficient of -0.253(p<0.01). The general and beauty-related factors showing significant correlation with indigestion were beauty culture career, number of holiday, and regular living habit. And regular living habit was shown to be the most relevant with the correlation coefficient of -0.260(p<0.001). 3. Results from the regression analysis showed that relevant factors having significant effects on indigestion were gender, beauty culture career, satisfaction on duty, eating speed, regular eating habit and regular living habit. And satisfaction on duty was found to have the greatest effect on indigestion. Conclusions: The findings of this study could be effectively used to develop a practical management strategy to prevent $beauticia{\acute{n}}s$ indigestion, and to promote $beauticia{\acute{n}}s$ health, and ultimately to improve the $beauticia{\acute{n}}s$ quality of life.

  • In the era of the rapid development of a tremendous number of new technologies and products, the emotional communication between products and users has become an important research topic. However, the user's emotional measurement methods have not been widely used in the field of product design. Besides, as an important space that can improve people's life quality and urban entertainment at the emotional level, seaside space also creates an atmosphere of frequent emotional communication among tourists, landscape and environmental facilities. To deduce the applicability and advantages and disadvantages of the experiential emotional measurement method in product design, this paper took the seaside seat users of Haeundae as the object and carried out the Self-report of the experiential emotional measurement method. Specifically, the experiment of Self-report was divided into two stages: prior survey and subsequent main investigation. Then the hypothesis was verified by using Bivariate Regression and Multiple Regression through SPSS. Furthermore, through the experiment of the Self-report, the applicability and advantages and disadvantages of experiential emotional measurement method in product design were derived. In the future, based on the applicability, advantages and disadvantages of the experiential emotional measurement method derived in this study, it is expected to become the fundamental and reliable data for the development of emotional measurement methods that can be suitable for product design.

  • Nowadays, Data-Network-AI (DNA)-based intelligent services and applications have become a reality to provide a new dimension of services that improve the quality of life and productivity of businesses. Artificial intelligence (AI) can enhance the value of IoT data (data collected by IoT devices). The internet of things (IoT) promotes the learning and intelligence capability of AI. To extract insights from massive volume IoT data in real-time using deep learning, processing capability needs to happen in the IoT end devices where data is generated. However, deep learning requires a significant number of computational resources that may not be available at the IoT end devices. Such problems have been addressed by transporting bulks of data from the IoT end devices to the cloud datacenters for processing. But transferring IoT big data to the cloud incurs prohibitively high transmission delay and privacy issues which are a major concern. Edge computing, where distributed computing nodes are placed close to the IoT end devices, is a viable solution to meet the high computation and low-latency requirements and to preserve the privacy of users. This paper provides a comprehensive review of the current state of leveraging deep learning within edge computing to unleash the potential of IoT big data generated from IoT end devices. We believe that the revision will have a contribution to the development of DNA-based intelligent services and applications. It describes the different distributed training and inference architectures of deep learning models across multiple nodes of the edge computing platform. It also provides the different privacy-preserving approaches of deep learning on the edge computing environment and the various application domains where deep learning on the network edge can be useful. Finally, it discusses open issues and challenges leveraging deep learning within edge computing.

  • A patient who went through maxillectomy can have soft palate defects including oronasal fistulas and suffer from dysphagia and dysarthria due to velopharyngeal insufficiency. This defect causes the food to enter nasal cavity and creates hypernasal sound which debilitates a quality of life. An obturator can rehabilitate the substantial oral tissue defects. The maxillary obturator separates the nasopharynx from the oropharynx during speech and deglutition by closing of the defect. For edentulous obturator patient, it is difficult to obtain proper retention due to reduced peripheral sealing. Therefore, the contours of the defects must be used to maximize the retention, stability, and support. Hollow type obturator can improve physiologic function by reducing weight than the traditional obturator. This case report describes a patient with hemi-maxillectomy who recovers mastication, speech, deglutition, and appearance with a maxillary obturator using physiological border molding of the velopharyngeal area and double-processing method.

  • This paper explores into the potential contribution of welfare science and technology(WST) to meeting the challenges of ageing. Drawing on the literature about gerontechnology, this paper considers the application of scientific knowledge for welfare of an aging population. WST for the improvement of the daily functioning of the elderly people can not only prevent, delay or compensate for the declines or impairments of coginitive and physical functions (by assistive technology) but also enhance personal ability to overcome problems either by supporting the person's abilities (by supportive technology) or by changing the environment (by public welfare technology). This paper draws attention to a paradigm change in the conceptualization of disability and its ramifications for the role of technology and aging. A range of approaches such as Barrier-Free design, Universal Design points to new directions of WST in which products and services are devised to improve the quality of life for all people, and hence enhancing the socio-economic vitality. It is suggested that the future of welfare science and technology will be based in large measure on its goal to reduce or prevent individual and structural lag in the relationships between people and their environments. Addressing issues of the broader physical and social environment will emphasize the goal of prevention and the view that environmental needs for aging population are changing over time.

  • The purpose of this study was to analyze the effects of name attractiveness on self-efficacy and emotional awareness in adult men and women. The subjects of this study were 300 males and females in their 10s and 30s living in the metropolitan area. However, 250 copies, excluding missing questionnaires during the collection process and incomplete questionnaires, were used for the analysis. As a result of analyzing the difference in name attractiveness according to factors, the lower the age group and the lower the academic level, the more dissatisfied they were with their names. Besides, the regression analysis conducted to verify the effect of name attractiveness on self-efficacy showed that the model's fitness was R2=.382 and the model's explanatory power was somewhat inferior, but β=.322, t-value 9.276, p<.001 were shown to be statistically significant, so name attraction directly affects self-efficacy. And the results of the regression analysis conducted to verify the effect of name attractiveness on emotionality turned out to be R2=.412. The regression analysis, which controls demographic variables such as gender, age, and academic level, was statistically significant as β=.326, t-value 6.408, p<.001. In other words, the name attractiveness affects emotional awareness. There is no empirical study that the name attractiveness can improve happiness or the quality of life, but it seems often among athletes that names are enhanced by the past.
