This study was performed to compare the shear strength of the bondings between stainless steel crown/direct type composite resin and stainless steel crown/indirect type composite resin. Four groups of bonding conditions were prepared. Two groups of bonding conditions were made by the indirect type composite resin system and the other two groups were made by the direct type composite resin system. The shear strength tests were carried out using universal testing machine, Model 4465 of Instron Co.. It was indicated that the bond strength values of the indirect type composite resins were higher than those of the direct type composite resins. TE-SE group was superior to the TE-ONE in indirect type resin system. These results were thought to be the high degree of the polymerization accompanied with temperature and pressure of the resin of indirect type resin. It was also found that indirect composite resin contains less amount of porosity in resin.

The purpose of this study is to provide basic data for more functional and more fitting clothing construction. The subjects were college women aged from 18 to 25 in June, 1997. Data were collected by anthropometry and photometry and analyzed by the characteristic of the upper body- The results are as follows: 1. After analyzing direct anthropometric data, 1 have analyzed the data by the characteristic in each somatotype, classified them and I have had 5 groups. Group 1 with middle height and standard type, group 2 with great height and standard type, group 3 with low height and slim type, group 4 with middle height and fat type, and group 5 with low height and a little fat type. 2. After analyzing indirect photometric data, 1 have analyzed them by the characteristic and I have had 4 groups. Group 1 with lean back type, group 2 with sway back type, group 3 with straight type and group 4 with bend forward type. 3. Through the mutual corresponding relation in the 5 groups classified with direct anthropometric measurement and the 4 groups classified with indirect photometric mea- surement, direct-group 1 comes the most corresponding to indirect-group 2, comes second to indirect-group 4, and comes third to indirect-group 1. Direct-group 2 comes the most corresponding to indirect-group 4, direct-group 3 comes the most corresponding to indirect- group 1, direct-group 4 comes the most corresponding to indirect-group 3, and direct-group 5 comes the most corresponding to indirect-group 1.

The purpose of this study is to investigate the relationship between behavior patterns(DISC) and direct indirect of social support from dental hygienists. The data used in this study were obtained from 171 dental hygienists who have been working on dental hospital or clinic in Pusan and Gyeongsangnam-do from 1st July to 30th August in 2011. In the level of direct indirect of social support according to subjects' general characteristics, higher educational level and non-religion was related with higher in direct of social support(p<0.05), and hygienists who worked in general hospital was related with higher indirect of social support(p<0.01). According to between behavior patterns(DISC) and indirect social support, these score were that I-type 3.55, D-type 3.53, C-type 3.41, and S-type 3.36. All behavior patterns(DISC) were similar with the indirect support. In direct support these score were that S-type 2.98 I-type 2.95, D-type and C-type 2.91. In frequency of behavior patterns(DISC), these were that I-type 56.7%, S-type 16.4%, C-type 14%, and D-type 12.9%. In correlation between factors, direction social support was correlated with I-type(p<.01) and C-type(p<.01) of behavior patterns(DISC). On based on these results, if the change of working environment, working condition will improve social support of dental hygienists. And education program have to developed for dental hygienists.

This study held human measurement for 200 male subjects in their twenties in full age living in Ningbo City, Zhejiang Province in China. Their lower body types were classified and grouped according to shapes and sizes. Consequently, representative body type reflecting shapes, sizes, and characteristics were chosen and presented with their measurement values to be used as the basic data for slacks pattern making and fitness evaluation. The following are the results of the analysis: 1. Homogeneity analysis was given to determine the correspondence relationships among index types, indirect types, and size types. Index Type 1 (H-Round), Indirect Type 2 (Adjacent Straight Legs & Slight Slant of Lateral Lower Body), and Size Type 1 (Medium-Thick) were correlated; Index Type 2 (A-Trapezoid), Indirect Type 1 (Bow Legs & Slight Slant of Lateral Lower Body), and Size Type 3 (Small-Slim) were corresponded; Index Type 3 (A-Balance), Indirect Type 3 (Balance Legs & Large Slant of Lateral Lower Body), and Size Type 2 (Tall-Normal) were mutually related. 2. Mahalanobis distance based on each shape factor (index or indirect) and size factor (absolute) was obtained, while an index-absolute representative body type group (47 people, 24.4%) and an indirect-absolute representative body type group (45 people, 23.7%) were chosen, each reflecting shapes, sizes, and characteristics. 3. The representative body type group of lower body shapes of Chinese males in their 20s had average measurement values, such as 169.15cm (stature), 73.32cm (waist circumference), 75.76cm (omphalion waist circumference), 91.08cm (hip circumference), 106.02cm (outside leg length), 53.96cm (thigh circumference), and 74.42cm (crotch length).

In general, speed control method of the elevator system has used motor pole change type or motor primary voltage control type. But it will change to vector control type in order to increase it's reliability, riding comfort and decrease material cost. It is the conception of vector control type in order to increase it's reliability, riding comfort and decrease material cost. It is the conception of vector control that primary current of the induction motor be controlled independently with magnetizing current(field current of DC motor) and torque current(armature current of DC motor). In this paper, by analyzing the effect of the time constant variation of rotor of the induction motor on the slip frequency type indirect vector control, a drive system for the motor will be constructed using a fuzzy slip frequency type indirect vector controller with fuzzy control method for estimating the vector time constant in the slip frequency type indirect vector control. The goal of this study is to enabling even more efficient speed control by constructing on elevator driver based on the newly developed drive system.

The purpose of a tracking control system is to track a moving target and to find the exact information of the target. If the platform of the tracking control system is equipped on a moving vehicle such as a ship, the tracking control system will treat even the additional platform motion. In order to avoid the complexity comprising the tracking control system, a process to treat the platform motion, named stabilizing system, must be separated from the tracking control system. In this paper, a method to comprise an attitude control system for the platform stabilization is proposed using an adaptive fuzzy control which is applicable to the system with structural and parametric uncertainty. The suggested adaptive fuzzy control algorithm is the 2nd/1st-type indirect adaptive fuzzy control algorithm using the advantages of 1st-type and 2nd-type indirect adaptive fuzzy control algorithm. Several experiments using the implemented stabilizing system are executed for verifying the effectiveness of the suggested method.

Backgrounds : Recently, commercial indirect moxibustion has been widely used as a substitute for traditional indirect moxibustion by clinicians due to its convenience in using. But, there has been lack of studies about the similarity of thermal stimulation between commercial indirect moxibustion and traditional indirect moxibustion. Objectives : To demonstrate commercial indirect moxibustion can substitute for traditional indirect moxibustion by comparing thermal stimulation between the two. Methods : We measured bottom temperature of commercial indirect moxibustion and traditional indirect moxibustion with various thicknesses of ginger and garlic. A clinical trial was performed on 18 healthy subjects to evaluate thermal stimualtion. The subjects were randomly assigned into two groups, traditional indirect moxibustion with ginger and garlic. The skin temperature and heating time were measured. They received moxibustion therapy with commercial indirect moxibustion and traditional indirect moxibustion according to their groups. Acupoint Chogcoe($LU_6$), Zusanli($ST_{36}$) and Tianshu($ST_{25}$) were used in each group for 3 times. Results : There was no difference in bottom temperature among commercial indirect moxibustion, traditional indirect moxibustion with 2mm ginger and 3mm garlic. No major difference was detected in the subjects' baseline data. There was no difference in skin temperature and heating time among these 3 type of moxibustions. Also, No major difference was detected in VAS score of thermal stimulation and frequency of burns among these 3 type of moxibustions. But, most subjects regarded their sensation weren't identical because of its own distinct characteristics. Conclusions : Commercial indirect moxibustion, traditional indirect moxibustion with 2mm ginger and 3mm garlic have same thermal stimulation. Thus, commercial indirect moxibustion can substitute for traditional indirect moxibustion.

The exploration of the interaction effect among the components of attractiveness is impossible; therefore, this study uses an indirect estimates approach with multiple scale items that can measure the interaction effect among the components of attractiveness to solve the problem of direct estimates. Previous studies focused on intra-store type competition as their subjects; subsequently, this study dealt with intra-store type competition as well as inter-store type competition in the competing and selecting activities among fashion retailing stores with different business models (such as department stores, road brand stores, discount stores, outlets and internet shopping malls). This study suggests a generalized model for shopping attractiveness of stores and proposes a fashion retailing store type attractiveness (FaRSTA) model instead of a simple relative importance between store selection standards.
