MPEG Audio compression algorithm is the international standard for the digital compression of high quality audio using mechanism of the perceptual coding based on psychoacoustic masking. It is necessary to discuss the constraints on designing of common filter banks for MPEG-2 BC and MPEG-2 AAC decoder system, which is not Down yet, mapping audio signals from the time domain into the frequency domain. In this paper, we present an architecture of common synthesis filter whcih can be used for MPEG-2 BC and MPEG-2 AAC decoder using recursive structure. The proposed algorithm is based on recursive architecture that effectively performs common compulsion.

The purpose of the study is to propose the plans promoting IS acceptances under the circumstances where the IS usage is semi-mandatory. Since the IS usage is critical to secure the organization's competitiveness, many researchers have endeavored to investigate the factors in promoting IS acceptance. While TAM(Technology Acceptance Model) has been generally applied under the voluntary circumstance, under the mandatory circumstance did many researchers come to realized the limit of applying the TAM on IS acceptance. This resulted in various research trials to identify the IS acceptance under the mandatory circumstance. However, no research to promoting IS acceptance under the recommend circumstance where the corresponding users are recommend to the IS rather than alternative systems exits. The study applied the concept of switching costs to the research model, identified users' acceptance variations, and finally proposed the promotion plans for IS acceptance. The findings illustrate that IS dependence levels tend to be increased when both user satisfactions from a psychological perspective and monetary benefits from an economic perspective make the switching costs higher. The study stresses that organizations should provide information systems which reduce users' time, costs, and endeavors in performing their tasks, rather than require to use them by compulsion.

Though modern banking organs were established in Korea with the Kanghwa Treaty as a momentum, the benefit of financing at that time, which was mainly given to merchants and industrialists and traders, was extremely limited to the fishermen. The fishermen who were out of favor with the benefit of financing of modern banking organs were forced to rely on high interest loans, a category of usury capital, issued by the middlemen (the Kaekju) who lent them the deficit of their necessary funds. The fact was that in the field of fisheries the middlemen who issued usury capital played the leading part in fisheries financing of the Late Yi Dynasty. The middlemen, however, sqeezed a part or all of surplus products and on occasion even necessary products out of the fishermen by means of outward compulsion of economy. Moreover they put the fishermen further in trouble by putting-out system. In order to keep on with the production of aquatic products, the fishermen with little capital and no property established the antinomic rotations with the middlemen whose disadvantageous terms they were inevitably to accept. Thus the middlemen who did business with the fishermen exercised their authority over them, securing a strong activity foundation in the field of fisheries. But the traditional form of the Kaekiu was transformed and gradually declined in the field of fisheries according as the market rules were proclaimed in 1914.

The police have a responsibility to exercise the police authority in the sphere of peril prevention. Such right may be decided at their discretion. So, as a management according to the police's discretion is based on order and compulsion, it can not help infringing the rights of the people. Therefore, the exercise of the police authority has to be accompanied by a legal management policy according to the principle of legal reservation based on the principle of constitutionalism. This study is to find proper directions of the police function through preparing reasonable plans to guarantee freedom and rights of the people at its maximum while maintaining the public peace and order.

This paper covers improvement of the humanoid robot platform HUBO2, known as the HUBO2+. As a necessity of the growth of the humanoid platform, a robust, reliable and user friendly platform is needed. From this standpoint, HUBO2+ is the most improved humanoid robot platform in the HUBO series. The mechanical design has been changed to increase the movable range and to stop joint compulsion. Additionally, all of the electrical parts are re-designed to be un-breakable in an unexpected situation. A smart power controller with robot status check panel is attached on the back. Additionally, a diagnosis tool, the HUBO-i, has been developed. Moreover, each joint motor controller of HUBO2+ has a Protection Function and a PODO system is provided for handling the robot easily.

This study was attempted to investigate the relationship between the academic achievement and the internal and external motivation of academic achievement. Here, the internal motivation of academic achievement refers to the case that a student feels the necessity of study and h satisfaction, expects rewards, or has interest in his study; external motivation of academic achievement means that a student has outward motivation such as other's recognition, rewards, or compulsion. As the result of this study, there showed significant difference in the academic achievement in proportion as the level of internal and external academic achievement motivation (P<.001). the students with the higher internal motivation and the lower external motivation turned out to have the highest effect of academic achievement; on the other hand, the students with the lower internal motivation and the higher external motivation showed the least academic achievement. There was 11.60 points-difference on the average between those two groups in terms of grade. The academic achievement and the internal motivation shows significant correlation(r=.25, P<.001) while academic achievement and the external motivation presents negative tendency (r=-.10). Through the results of regression analysis, the estimation of the academic achievement by the two variables to academic achievement motivation was 6.22%(P=.0001)

Objective : The objective of this study was to examine the mental health status and its correlates of the marriage-migrant women in Seoul, Korea. Methods : One hundred and seventy marriage-migrant women and one hundred and sixteen married Korean women were recruited from community to complete Symptom Check List-90-Revision (SCL-90-R). Marriage-migrant women were also asked for their socio-demographic factors, acculturative stress, family-relationship stress, and social support. The scores on the SCL-90-R were compared between marriage-migrant women and married Korean women, and the correlates of marriage-migrant women's mental health were investigated. Results : Compared to married Korean women, marriage-migrant women showed lower levels of mental health problems including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, paranoid ideation, and psychoticism. Longer length of residence in Korea, lower family income, social support, higher acculturation stress, and family relationship stress were all associated with mental health problems of marriage-migrant women Results : Our results suggest that mental health of marriage-migrant women is not necessarily bad, and several factors may affect their mental health. However, further studies are required in a larger representative sample to confirm the study findings.
