The author has measured the duration of occlusal sounds during centric occlusal tapping in 30 patients with TMD and 30 normal subjects as controls, and then correlated the duration of occlusal sounds with CMI, amount of centric slide, midline deviation, habitual side of mastication, and presence of occlusal interference. The results were as follows 1. The duration of occlusal sounds during centric occlusal tapping were 36.26 msec in TMD patients and 22.8 msec in normal subjects (p<0.01). 2. The correlation between duration of occlusal sounds and CMI was significant (p<0.01). 3. The correlations between duration of occlusal sounds with amount of centric slide, midline deviation, habitual side of mastication, and presence of occlusal interference were not significant (p<0.05).

The accuracy of CCD observations obtained at the Korean 1.8m telescope has been studied. Seventeen comparison stars in the vicinity of the cataclysmic variable BG CMi have been measured. The 'artificial' star has been used instead of the 'control' star, what made possible to increase accuracy estimates by a factor of 1.3-2.1 times for 'good' and 'cloudy' nights, respectively. The algorithm of iterative determination of accuracy and weights of few comparison stars contributing to the artificial star, has been presented. The accuracy estimates for 13-mag stars are around $0.^m002$ mag for exposure times of 30 sec.

This paper addresses the collusive bidding that functions as a potential obstacle to a fully competitive wholesale electricity market. Cooperative game is formulated and the equation of its Nash Equilibrium (NE) is derived on the basis of the supply function model. Gencos' willingness to selectively collude is expressed through a bargain theory. A Collusion Incentive Index(CII) for representing the willingness is defined through computing the Gencos' profits at NE. In order to keep the market non-cooperative, the market operator has to know the highest potentially collusive combination among the Gencos. Another index, which will be called the Collusion Monitoring Index(CMI), is suggested to detect the highest potential collusion and it is calculated using the marginal cost functions of the Gencos without any computation of NE. The effectiveness of CMI for detecting the highest potential collusion is verified through application on many test market cases.

This study was carried out to investigate nutrients intake and dietary environments of rural and asylum elderly in partial Kyunggi area. Results were as followes: (1) Educational level of 2 groups of rural and asylum elderly was only literacy, And rural elderly worked more than the aged of asylum. (2) The nutrients intake of rural elderly was very small quantity: Energy intake was 62% of RDA, that of protein 59%, calcium 56%, and iron 72% only. This nutrients intake state was lower than that of asylum elderly. (3) Health score CMI was selected 31 cases of items for aged. Ryal elderly received 11.7/31, but the scores of asylum elderly were 7.1 only. It means that asylum elderly felt more healthy than rural. (4) The correlation Serum TG was significant with protein fat and calcium, but serum calcium was not significant with intake of calcium. The nutrients intake was correlated with CMI score and dietary habit score.

The international business community has been seeking to change paper based bill of lading to electronic bill of lading for the recent years. The reasons for the need for electronic bill of lading are the benefits to international traders:they are fast to issue, transmit and process. These benefits are eliminate the crisis of bill of lading and come down the cost international business community have to charged. The purpose of this paper is to investigate and issue the problems of the present methods of the Electronic Bill of Lading and find implications to commercialized the Electronic Bill of Lading in the basis of the laws and practices of the international trade. Various attempts are offered to achieve this benefits for the last years such as SeaDocs Project, CMI Rules for Electronic Bills of Lading, and Bolero Project. But these methods are yet to be achieved the goals to substitute the paper-based Bill of Lading to Electronic Bill of Lading entirely.

This paper present in-wheel BLDC motor using parallel winding. The voltage of proposed motor is higher than Y-connection three phase BLDC motor in order to separated connection. When the stator resistance and inductance are stable, maximum phase current and maximum torque is increased by high injected voltage. The proposed motor is verified from experimental result of the 2[kW] in-wheel motor on electric vehicle drive.
