In order to adapt to the economic change with the rapid world change, the wise consumers should have positive cognizance of their roles and are requested to fulfil their duties as a consummer. Such capability of the consumer could be acquired from home, mass media and school, and specially the role of mother at home would have a great influence on their early children's consummer activities. The purpose of this study was to investigate the interrelationship of the consumer behavior between mother and their children. As a result of this study, the mother with higher educational background could manage effectively the allowance of the children. The mother with older age had a great influence on the consumer's role of the children and high record of the execution. Employed mother had higher level of execution for the consumer's rights than their count part. Accordingly, the consumer behavior of the mother will have an influence on the children's consumer behavior. Such a result showed the meaningful statistic relations(r=3.6, p<.001) for the economy activity of the children the home management and economy life of the mother, and the purchasing activity of the children including the execution of the consumer's right. In their regard, there was the significant statistic relations(r=19, p<.05) between the children's pocket money and the housekeeping management of the mother. In the meantime, it showed that another changing factor concerned with the consumer behavior of the mother have little influence the children's allowance.

A novel approach to estimate the real time moving trajectory of an object is proposed in this paper. The object position is obtained from the image data of a CCD camera, while a state estimator predicts the linear and angular velocities of the moving object. To overcome the uncertainties and noises residing in the input data, a Kalman filter and neural networks are utilized. Since the Kalman filter needs to approximate a non-linear system into a linear model to estimate the states, there always exist errors as well as uncertainties again. To resolve this problem, the neural networks are adopted in this approach, which have high adaptability with the memory of the input-output relationship. Kohonen Network(Self-Organized Map) is selected to learn the motion trajectory since it is spatially oriented. The superiority of the proposed algorithm is demonstrated through the real experiments.

지필검사는 매우 제한적인 학생정보만 제공한다. 그래서 온라인상에서 웹기반으로 실시하는 컴퓨터이용검사가 개발되고 시도되어지고 있다. 그러나 이러한 기존의 시스템은 문항을 자유롭게 이동하며 시험을 치를 수 없다는 단점을 가지고 있다. 이러한 단점으로 인하여 각 문항에 소요된 시간, 답안 변경 내역, 각 문항의 방문 횟수등과 같은 심화된 정보를 얻어낼 수 없다. 이러한 심화된 정보는 교육평가 영역에서 매우 중요시되는 정보이다. 심화된 정보를 알기 위해서는 응시자가 문항을 자유롭게 이동하면서 시험을 치를 수 있어야 한다. 그래서 본 논문에서는 기존의 시스템이 제공하는 기본 정보 이외에 심화된 정보를 얻을 수 있는 시스템을 개발하였다. 개발된 시스템을 67명의 학생들에게 지필검사와 함께 각각 적용하고 설문 조사를 실시하였다.

In this paper, a high-performance, low-area gradient-magnitude calculator architecture is proposed, based on approximate image processing. To reduce the computational complexity of the gradient-magnitude calculation, vector properties, the symmetry axis, and common terms were applied in a hardware-resource-shared architec-ture. The proposed gradient-magnitude calculator was implemented using an Altera Cyclone IV FPGA (EP4CE115F29) and the Quartus II v.16 device software. It satisfied the output-data quality while reducing the logic elements by 23% and the embedded multipliers by 76%, compared with previous work.

A charge-trap flash (CTF) thin film transistor (TFT) memory is proposed at a low-temperature process (≤ 450℃). The memory cell consists of a sputtered oxide-nitride-oxide (ONO) gate dielectric and Schottky barrier (SB) source/drain (S/D) junctions using nickel silicide. These components enable the ultra-low-temperature process to be successfully achieved with the ONO gate stacks that have a substrate temperature of room temperature and S/D junctions that have an annealing temperature of 200℃. The silicidation process was optimized by measuring the electrical characteristics of the Ni-silicided Schottky diodes. As a result, the Ion/Ioff current ratio is about 1.4×10⁵ and the subthreshold swing and field effect mobility are 0.42 V/dec and 14 cm²/V·s at a drain voltage of −1 V, respectively.

Recently, convergence engineering is emerged technology to make a whole new conceptual methodology attractively more than we previously developed the distinct technology for engineering college students particularly. Based on convergence methodology, we utilize the open-source electronic prototyping platform named Arduino enabling users to create interactive electronic objects and the automata that is generally referred to a wooden moving, mechanical device or art of work in order to develop the creative convergence education program. We have confidence that our education program can lead the development of automata and information technology simultaneously and can nurture talented students who have creativity and originality in engineering college.

SPC와 EPC의 통합은 연속공정산업에서 성공적으로 사용되고 있다고 널리 인식되어 있다. 그러나, 이산적인 부품 제조공정의 모니터링과 연속 생산공정 모니터링 양쪽 모두를 포함하는 하이브리드(hybrid)산업에서의 이들 기법을 적용하기 위해서는 샘플링비율, 고장감지, 실시간 보정과 공정통제 등에 관한 연구가 필요하다. 본 연구에서는 SPC와 EPCD의 차이를 비교분석하고, 하이브리드 산업에서 SPC와 EPC를 성공적으로 통합하여 제품공정품질관리에 적용하는 사례연구를 제시하고자 한다.

Methods : The experimental group included 64 children in the fourth . fifth and sixth grades. from one elementary school. whose BMI was in the H5th percentile or more for their age groups. The control group had 6 1 students from a different one elementary school whose conditions were the same as those of the experimental group. Results: After the stage of change exercise intervention was applied, the BMI of the experimental group decreased by a significant enough degree to conclude that the program was effective in decreasing BMI. After the application of the program. the experimental group experienced a significant increase in their helping relationships. counter-conditioning . reinforcement management and stimulus control compared 10 the control group. After the program. self-efficacy in terms of exercise increased significantly in the experimental group. Conclusion: A stages of change exercise intervention program has been shown to engage individual students and encourage them 10 maintain a higher fitness level that promote s self-efficacy in exercise and therefore moves them towards healthier lifestyles.

Vertical forest distribution is one of the important factors to understand various ecological mechanism such as succession, disturbance and environmental effects. LiDAR data provide information, both the horizontal and vertical distribution of forest structure. The laser scanner survey provided a point cloud, in which the x, y, and z coordinates of the points are known. The objectives of this study were 1) to analyze factors of forest structure such as individual tree isolation, tree height, canopy closure and tree density using LiDAR data and 2) to compare the forest structure between outer and interior forest. The paper conducted to extract the individual tree using watershed algorithm and to interpolate using the first return of LiDAR data for yielding digital surface model (DSM). The results of the study show characters of edge such as more isolated individual trees, higher density, lower canopy closure, and lower tree height than those of interior forest. LiDAR data is to be useful for analyzing of forest structure. Further study should be undertaken with species for more accurate results.
