Prior studies on child development have focused mainly on environmental variables including mother variations. However, several studies proved that child variables, especially inherited temperament, influence or change the environment. The current study investigates the temperament of 5 - to 8 - month - old infants. One hundred and forty-three mothers of the infants responded to the RITQ that was devised by Carey and McDevitt (1978). The RITQ examined 9 temperamental categories. Based on the score, the subjects were divided into five subgroups-Difficult, Slow-to-Warm-Up, Intermediate High, Intermediate-Low, and Easy. The important findings are as following : (1) There were significant sex differences. Females appeared to have significantly more representation in the slow-to-warm-up, intermediate-high, and intermediate-low groups. There were more males in the easy group. In the comparison of the two sexes as to the mean score in the nine categories males were found to be more approaching, less intensive, positive mood, and highly distractible. (2) Infants' temperament was not related to the mothers' education level and their work status. (3) The mothers' global ratings were consistent with subgroup temperament characteristics.

The purpose of this research is to develop and evaluate an emotional intervention program for maladaptive preschoolers. The emotional intervention program focused on nurturing the ability to express emotions in healthy ways and how to empathize with others while the preschoolers perceives negative emotions. The participants in this study were nineteen preschoolers, residing in S city. Nineteen subjects were assigned to an experimental group practicing an emotional intervention program. The preschoolers participated in 8-session programs once a week over the course of eight weeks. Descriptive statistics, paired t-test and hierarchical cluster analysis were performed. The results of this study were as follows. First, there were significant differences between posttests and pretests results. The results showed a decrease in maladaptive preschooler's problematic behaviors and aggressive strategies. The maladaptive preschoolers showed more representations of anxiety, avoidance/withdrawal, and deregulated/aggression. In addition the results also showed a decrease in preschooler's representations of anxiety, avoidance/withdrawal, and deregulated/aggression.

A new linkage framework between elastic shell element with finite rotation and computar-aided geometric design (CAGD) (or surface is developed in the present study. The framework of shell finite element is based on the generalized curved two-parametric coordinate system. To represent free-form surface, cubic B-spline tensor-product functions are used. Thus the present finite element can be directly linked into the geometric modeling produced by surface generation tool in CAD software. The efficiency and accuracy of the Previously developed linear elements hold for the nonlinear element with finite rotations. To handle the finite rotation behavior of shells, exponential mapping in the SO(3) group is employed to allow the large incremental step size. The integrated frameworks of shell geometric design and nonlinear computational analysis can serve as an efficient tool in shape and topological design of surfaces with large deformations.

In reverse engineering area, it is rapidly developing reconstruction of surfaces from scanning or digitizing data, but geometric models of existing objects unavailable many industries. This paper describes new methodology of reverse engineering area, good strategies and important algorithms in reverse engineering area. Furthermore, proposing reconstruction of surface technique is presented. A method find base geometry and blending surface between them. Each based geometry is divided by triangular patch which are compared their normal vector for face grouping. Each group is categorized analytical surface such as a part of the cylinder, the sphere, the cone, and the plane that mean each based geometry surface. And then, each based geometry surface is implemented infinitive surface. Infinitive average surface's intersections are trimmed boundary representation model reconstruction. This method has several benefits such as the time efficiency and automatic functional modeling system in reverse engineering. Especially, it can be applied 3D scanner and 3D copier.

This study explored age and sex differences in preschoolers' narrative representations of their mothers. Subjects were 120 3-, 4-, 5- and 6-year-old children, with 15 boys and 15 girls in each age group. Using the MacArthur Story Stem Battery(Bretherton et al., 1990), observations were made to obtain children's narrative representations of their mothers. content themes and emotional responses. Boys' representations were more negative and less positive than girls' regardless of their age. Boys talked about more aggressive themes and showed more anxiety and less joy. Five and 6-year-old children had less negative and disciplinary representations of their mothers than 3- and 4-year-olds. Six-year-olds showed less prosocial themes than 3- and 5-years, and fewer aggressive themes than 3-and 4-year while they showed less joy, distress and concern responses than 3-years.

In reverse engineering area, the reconstruction of surfaces from scanned or digitized data is being developed, but geometric model of existing objects is not available in industries. This paper presents the new approach to the reconstruction of surface technique. A proposed methodology finds base geometry and blends surface between them. Each based geometry is divided by tri-angular patches which are compared with their normal vector for face grouping. Each group is categorized analytical surface such as a part of cylinder, sphere and cone, and plane shapes to represent the based geometry surface. And then, each based geometry surface is implemented to the infinitive surface. Infinitive surface's intersections are trimmed by boundary representation model reconstruction. This method has several benefits such as time efficiency and automatic functional modeling system in reverse engineering. Especially, it can be directly applied 3D fax and 3D copier.

This paper suggests a multimedia educational system which has the ability to extract intelligent instruction on the distributed environment. The proposed system is designed for supporting individual instruction and real time user interaction. As the system based on CORBA, we put group managing module on it for multi user environment, so it has ability for distributed computing facilities. Using MHEG standard, we can provide multimedia courseware and real time user interaction. To diagnose students' responses and generate evaluations, we use several linguistic variables of fuzzy theory. There are two major advantages for using this system. This system can provide dynamic generation of problems and the ability to provide a dynamic instruction strategy. And it can increase reusability of courseware material for using standard of multimedia representation and communication. We use CORBA and MHEG to overcome the disadvantage of the Web, passive protocol and poor interactivity, HTTP.

This paper presents a bitwidth optimization algorithm for efficient hardware sharing in digital signal processing system. The proposed algorithm determines the fixed-point representation for each signal through bitwidth optimization to generate the hardware requiring less area. To reduce the operator area, the algorithm partitions the abstract operations in the design description into several groups, such that the operations in the same group can share an operator. The partitioning result are fed to a high-level synthesis system to generate the pipelined fixed-point datapaths. The proposed algorithm has been implemented in SODAS-DSP an automatic synthesis system for fixed-point DSP hardware. Accepting the models of DSP algorithms in schematics, the system automatically generates the fixed-point datapath and controller satisfying the design constraints in area, speed, and SNR(Signal-to-Noise Ratio). Experimental results show that the efficiency of the proposed algorithm by generates the area-efficient DSP hardwares satisfying performance constraints.

There appears to be an increased incidence of anxiety symptoms in association with certain medical illness. It is usually assumed that certain medical disorders are directly associated with anxiety symptoms in that the pathophysilolgy of the medical illness somehow causes the anxiety symptoms. However, the pathophysilolgies of many such medical illnesses as well as anxiety are not known and no discrete group of medical illnesses is clearly more likely to produce anxiety symptoms than any other Moreover, anxiety symptoms may be the representation of other psychiatric symptoms, like depression and delirium. Though it is important to differentiate primary and other causes(secondary) of anxiety clinically, the clear differentiation is somewhat arbitrary, as the confusion of mind-body dichotomy. for the purpose of accurate treatment of anxiety symptoms relating medical illness, this review article focuses on those clinical features and mechanisms of anxiety that are potentially useful in differential diagnosis.

We propose an end-to-end neural coreference resolution for the Korean language that uses an attention mechanism to point to the same entity. Because Korean is a head-final language, we focused on a method that uses a pointer network based on the head. The key idea is to consider all nouns in the document as candidates based on the head-final characteristics of the Korean language and learn distributions over the referenced entity positions for each noun. Given the recent success of applications using bidirectional encoder representation from transformer (BERT) in natural language-processing tasks, we employed BERT in the proposed model to create word representations based on contextual information. The experimental results indicated that the proposed model achieved state-of-the-art performance in Korean language coreference resolution.
