  • This paper concerns automatic hardware synthesis from data flow graph (DFG) specification for fast HW/SW cosynthesis. A node in BFG represents a coarse grain block such as FIR and DCT and a port in a block may consume multiple data samples per invocation, which distinguishes our approach from behavioral synthesis and complicates the problem. In the presented design methodology, a dataflow graph with specified algorithm can be mapped to various hardware structures according to the resource allocation and schedule information. This simplifies the management of the area/performance tradeoff in hardware design and widens the design space of hardware implementation of a dataflow graph compared with the previous approaches. Through experiments with some examples, the usefulness of the proposed technique is demonstrated.

  • Technological innovation depends on the quality of workers, whose ability is the key component to raise business competitiveness. Our study evaluates how satisfactory is the training of workers at small and medium sized firms, and suggest how to improve upon it. We show the theoretical framework for the relation between customer satisfaction and their behavioral intent on the one side, and factors of training service quality. Our result show: (1) Factors affecting customer satisfaction are, in descending order of importance, expertise, policy, follow-up service, attitude and behavior, and convenience. (2) Contrary to established views on the service quality, satisfaction for training would not be the prerequisite variable for intent to act, in case of training service quality. (3) Satisfaction level for training depends on the type of organization in charge of training (government, university, or private sector.) It also varied among different types of business (L-type, A-type, and J-type.) Small and medium sized firms find it difficult to commit to training education due to lack of money and manpower. The recent expansion of free training service would address part of this problem. On the other hand, the outfit in charge of training could boost service quality by customizing their training program to the type of business they cater to.

  • With the increasing population of companion dogs, the social cost derived from their behavioral problems is increasing. Therefore, it is important to understand the environment to provide experience for dogs via interactions with their owners to prevent and solve these problems. The parenting behavior of dog owners as an environmental factor has a profound impact on the behavior development of dogs, as does the parenting behavior on children. Therefore, this study aimed to develop a scale to assess the dog owner's parenting behavior. Exploratory factor analysis involving 300 participants resulted in a scale with four subscales, Positive Education, Involvement of Socialization, Intimacy, and Stable Responses, and 19 items. Confirmatory factor analysis was then performed to verify its reliability and validity. The result of parenting behaviors assessed by this scale was significantly different between a group with dogs with problematic behavior (n = 141) and those without (n = 159). Overall, a dog owner's parenting behavior involves affection and control aspects, but the role required specifically in the control aspect is distinguished from the parenting behavior with children. The findings in the present study will provide dog owners with effective education that will help prevent dogs from developing behavioral problems.

  • An approach for game bot detection in massively multiplayer online role-playing games (MMORPGs) based on the analysis of game playing behavior is proposed. Since MMORPGs are large-scale games, users can play in various ways. This variety in playing behavior makes it hard to detect game bots based on play behaviors. To cope with this problem, the proposed approach observes game playing behaviors of users and groups them by their behavioral similarities. Then, it develops a local bot detection model for each player group. Since the locally optimized models can more accurately detect game bots within each player group, the combination of those models brings about overall improvement. Behavioral features are selected and developed to accurately detect game bots with the low resolution data, considering common aspects of MMORPG playing. Through the experiment with the real data from a game currently in service, it is shown that the proposed local model approach yields more accurate results.

  • Objectives : This study aims to investigate the effectiveness of an internet-based anger management program for school-aged children. Methods : Forty-eight elementary school students took part in an anger management training program; subsequently, participants, their parents, and their teachers answered questionnaires assessing the participants' anger, aggressiveness, and other emotional/behavioral problems, pre- and post-training. Results : At the post-training self-assessment, the participants showed significant reductions in their "anger-out" tendencies and physical aggressiveness. In addition, the effects of the program on "anger-out" tendencies, aggressiveness, anger and peer relational problem were found to be more significant in participants who reported depressive symptoms. Teachers rated the participants' peer-relational problems as having decreased after the training. Conclusion : The proposed internet-based anger management program had a significant effect on the school-aged children's abilities to control their anger.

  • In ASIP design, compiler is required for performance evaluation of processors being designed. The design of machine specific compiler is time consuming. This paper presents the system which generates C compiler from MDL descriptions. Compiler generation using MDL can support user retargetability and concurrency between compiler design and processor design. However, it must overcome semantics gap between compiler and machine. To handle this problem, the proposed system maps behavioral descriptions to library which contains abstract behavior for each tree pattern. Using mapped instructions and information on register file usage, the proposed system generates back-end interface function of the compiler. Generated compilers, for MIPS R3000, ARM9 cores, have been proved by application programs written in C code.

  • This study was designed to examine the relations of home environment, locus of control, social support and behavior problems of fourth-grade Korean-Chinese children in Yanbian in China. The subjects were 190 children who completed the locus of control and social support scale and their parents who completed the Child Behavior Checklist. T-test, correlation analysis, and multiple regression analyses were conducted. Mother's education level, and psychological and physical environment at home were negatively related to children's behavior problems. The scores of internal locus of control and support from the teacher were negatively related to children's behavioral disturbances. The factors with the greatest contribution to explaining behavior problems of Korean-Chinese children in Yanbian were found to be physical environment at home, internal locus of control, and teacher's social support.

  • Purpose: The study was done to investigate behavioral problems in toddlers who were born prematurely and to analyze related factors. Methods: A cross-sectional explorative study was conducted with 72 preterm birth (PTB) children at 24 to 41 months of corrected age who were born at 28 to 37 weeks' gestation. During home visits, behavior problems were assessed using the Behavior Rating Index for Children (BRIC). Using a BRIC score of ${\geq}30$, children with suspected behavior problems were grouped in the non-regular behavior group. Results: Of the children, 38.9% belong to the non-regular behavior group. The mental development index score for the Korean-Bayley Scale of Infant Development- II was higher for the non-regular behavior group compared to the regular behavior group (t=2.26, p=.027). Logistic regression analysis showed that lower maternal attachment (<96, OR=3.4, 95% CI[1.1, 10.4]) and higher parenting stress (${\geq}97$, OR=4.8, 95% CI[1.3, 17.3]) were independently related to non-regular behavior. Conclusion: PTB Toddlers are at risk for behavior problems which are associated with low cognitive performance. Maternal-child attachment and maternal parenting stress were strongly related to behavior problems in these children. More attention is needed to understand possible behavior problems in young children with PTB, particularly focusing on maternal-child interaction and maternal mental well-being.

  • Purpose: The purpose of this study was to investigate the patterns of smoking relapse and to identify risk factors related to smoking relapse among those successful in smoking cessation at the smoking cessation clinics of public health centers. Methods: Data were collected from 1,705 six-month quitters and analyzed by the Kaplan-Meier analysis and the Cox proportional hazard model. Results: The rate of smoking relapse was 38.2% in 1 year, 44.4% in 2 years, and 47.8% in 5 years. The vast majority of relapse (62.3%) occurred within the first six months after quitting. The risk factors related to smoking relapse were age (HR 1.964: 95% CI 1.545, to 2.497), nicotine dependence (HR 1.293: 95% CI 1.087 to 1.539), problem drinking (HR 1.497: 95% CI 1.116 to 2.008), behavioral therapy type (HR 1.398: 95% CI 1.193 to 1.638), and nicotine replacement therapy type (HR 1.363: 95% CI 1.077 to 1.724). Conclusion: For reducing smoking relapse, it is necessary to develop a smoking relapse prevention program for the first six months after quitting and to strengthen behavioral therapy in the course of smoking cessations clinics.
