This article examines the origin and growth of Jecheon Herbal Market(JHM). JHM was established in 1928 at the Jecheon Market Main causes of the growth of JHM is widely considered as the fact that it was located to the sources of herbal product, domestic or wild, and its convenient access in transportation aspect. Since the Independence of Korea, the control of the import of herbal medications from abroad served for the main factor of JHM's growth. Nowadays JHM is estimated as second to Gyungdong Herbal Market in total. However, among production-oriented markets it has been ranked first.

Assuming that the Capability Maturity Model Integration for Development v1.2 (CMMI) could be applied to an organization more effectively if the content similarities among practices were improved in terms of structure and composition, this paper presents the analysis of the correlations between the CMMI Specific Practices (SP) and Generic Practices (GP) for the Maturity Level 2 and 3 Process Areas using the Chi-square independence test. According to the analysis, a 22.2% correlation was observed. To minimize the problem of repeatedly applying similarities, 6 GPs that are highly correlated with the SPs were grouped together. Then, three different improvement plans: 1) development of a standard template-based project plan, 2) establishment of a configuration management system based on open source software to control work products and leverage experience, and 3) establishment of project assurance through an independent quality assurance-based organization and intensive review by higher-level management - were defined.

In this paper, finite impulse response (FIR) smoothers are proposed for discrete-time systems. The proposed FIR smoother is designed under the constraints of linearity, unbiasedness, FIR structure, and independence of the initial state information. It is also obtained by directly minimizing the performance criterion with unbiased constraints. The approach to the MVF smoother proposed in this paper is logical and systematic, while existing results have heuristic assumption, such as infinite covariance of the initial state. Additionally, the proposed MVF smoother is based on the general system model that may have the singular system matrix and has both system and measurement noises. Thorough simulation studies, it is shown that the proposed MVF smoother is more robust against modeling uncertainties numerical errors than fixed-lag Kalman smoother which is infinite impulse response (IIR) type estimator.

The characteristics of image quality of a color CRT (cathode ray tube) monitor are studied by changing the contrast and brightness levels. The resolution is assessed by SQRI (square root integral) measured at 9 different combinations of the contrast and brightness levels. The chromaticity coordinates and luminances of red-green-blue channels as a function of the digital value are measured at these combinations and the relationships among the constant-channel chromaticity, color gamut, maximum luminance of a white point with the channel independence are analyzed. From the results, the optimized combination of levels is obtained.

The following study to enhance children's creativity in the context of diverse cultures and ethnic groups, and utilizes various programs from different countries aimed at 5 year old children with the Nuri framework. The study also seeks to measure pre and post play behaviors, creativity levels, and thinking capabilities of the children, then compare these results with those from a control group. Analysis of the results indicates that children who experienced programs from various countries through a multicultural approach had much higher levels of fluency, adaptability, originality, and imaginative capabilities than children who had not experienced such programs. Among the children's creative play behaviors, intrinsic motive-magination, sensitivity-curiosity, longetivity-concentration, various forms of interest-challenge, and leadership-independence were all found to be significantly higher.

The separation of scintillation phenomena concurrent with rain attenuation phenomena can be accomplished by filtering. Based on the analysis of satellite signal fading during rain, scintillation and rain attenuation phenomena are examined and extracting from raw data by using adaptive IIR high-pass filter and adaptive IIR low-pass filter. Adaptive IIR filter are designed by using the algorithm of Least Mean p-Power (LMP) Error Criterion which have been modified by Quantizing Gradient technique. This algorithm reduces amount of multiplication computational equal to the length of input data. It is prove here that the convergence speed, variance, bias independence on p values. For this application, p=1 is chosen. The procedure of application ...

Bo-Back-N ARQ is widely used in packet networks for error and flow control methanisms. This paper analyzes the network throughput under the go-back-N schem. Contrast to other analytic methods which assume independent frame losses or the first order Markov frame analytic methods which assume independent frame losses or the first order Markov frame losses concoptually, the proposed method takes into account the correlation between successive frame losses in a congested node. Computer simulation shows that our method generates more accurate performance results that independent assumption method. We apply the proposed method to analyze the performance of BWM in high speed networs. Our results show that BWM maintains the independence between traffic streams.

This paper is aimed at comparing the attitudes of parents and the psycho-sociogenic aspects of the children of Korean and Japan. The data for the analysis were derived from questionnaires administered to the 4th, 5th, and 6th-grade children in Korean and Japan. The questionnaires were designed to survey children's perception of their parents'child-rearing and the psycho-sociogenic aspects of the children's personality in Korea and Japan. The child-parent relationships identified by the children were measured by the items indicating the degree and the extent to which they felt their parents' dissatisfaction, complaints, strictness, expectation, interference, worry, indulgence, blind obedience, contradiction and disagreement. The psycho-sociogenic aspects of the children's personalities were measured by the items indicating the degree and extent of how they felt about their own sociablility, independence, aggressiveness, extent of how they felt about their own sociability, independencem aggressiveness, participation in groups. Spontaneity, self-control and public spirit.

Field orientation of rotating field machines is influenced by various machine parameters. Most unpleasant are those parameters which vary during machine operation, such as the stator and rotor resistances. Permanent influences of resistance variation in steady state operation could have serious consequences. Also transitory influences are often disturbing. In this paper a control method for a current-fed synchronous machine is presented in which both permanent and transitory parameter influences are suppressed as much as possible.

Physical therapy for patients with Multiple sclerosis, Parkinson's disease, Spinal cord injury. Osteoporosis, CVA and Cerebral Palsy often includes the evaluating and teaching of rolling movements. Motor abilities such as rolling from a supine to a prone position, moving to sitting. getting up on all fours and ultimately standing up from a supine position. represents progression toward physical independence. Rolling is important functional abilities for need to dressing, decubit prevent. bed mobility, neck control, crawling, creeping, sitting, standing and walking. The purposes of this study were to describe motor development concept and rolling task patterns and to approach the therapeutic exercises.
