It is very important to explore new management theories that are better in line with the modern service economy era in order to cement the foundation of the service industry in this rapidly changing business environment. This study examined the relationship between service essentials and job performance by service industry, and verified and discussed in depth whether there is difference between service essentials and job performance by demographic characteristics. The results of this study are as follows: First, an analysis of the effect of service essentials on job performance found the interaction, horizontality and harmony of service essentials had positive effects on performance, but the relationship didn't. Next, an analysis of the effect of service essentials on job performance by representative service industry showed that in the transportation industry, interaction and harmony had positive effects on performance, but relationship and horizontality didn't affect performance. In the financial and insurance industries, horizontality and interaction had positive effects on performance, but harmony and relationship didn't affect performance. Accommodation and food industries, interaction, horizontality and harmony had positive effects on performance, but relationship didn't affect performance. In the medical and health industries, interaction and horizontality had positive effects on performance, but relationship and harmony didn't affect performance. In terms of demographic characteristics, in the financial and insurance industries, interaction and harmony showed a significant difference by age, but only horizontality showed a difference by the number of years of service. In the accommodation and food industries, only horizontality showed a difference depending on the number of years of service. In the medical and health industries, relationship, horizontality and harmony showed a difference depending on the number of years of service, but only horizontality showed a significant difference by marital status. In the future, comparative national studies are needed for all industrial groups.

In ultra precision machining, it is necessary to adjust the horizontality and reference position of a workpiece in a noncontact manner. For this, a simple process by measuring impedance between a tool tip and a workpiece which are connected to impedance analyzer is proposed. As the distance between the tool and the workpiece gets closer, the reduction rate of impedance becomes higher over all frequency ranges. By setting threshold value of impedance reduction rate at specific frequencies through preliminary experiments, the distance between the tool and the workpiece can be predicted and it directly enables us to horizontalize the workpiece and to set the tool to the desired reference position.

The purpose of this study is to evaluate the differences of visual effects by variations in the location and width of the waist band of one-piece dress. The stimuli are 24 samples: 8 variations of the location of the waist band and 3 variations of the width of the waist band. The data has been obtained from 50 fashion design majors. The data has analyzed by Factor Analysis, Anova, Scheffe's Test and the MCA method. The results of the study are as follows: According to the result of factor analysis of the visual effects based on the changes in the location and width of waist bands for one-piece dress, four factors were identified - verticality of whole-body, horizontality of upper-body, curves of lower-body and shape of breast. Whole-body verticality and upper-body horizontality were found to be the most important factor among them. In all of the four factors of the visual effects, significant differences were observed according to the location of the waist bands for one-piece dress. The visual effects were evaluated positively when the waist bands were positioned above the natural waist line and negatively when the waist bands were positioned below the natural waist line. In addition, significant differences were observed in the visual effects according to the width of waist bands when the waist bands were positioned above the natural waist line, and visual effects were better when the band width was 3.5cm and 4.5cm than the others. The interaction of the visual effect showed significant differences in horizontality of upper-body, curves of lower-body and shape of breast.

Casing Oscillator is a construction machine that used to insert casings which is based on construction of a building or bridge into the ground. The purpose of using casing supports a pile or in case when heavy loads and moments happens. It is very important that the casings are retaining perpendicular to sea level regardless of the slope of the ground. So it requires that Casing Oscillator keep horizontality. But, it was useless a horizontal control without another heavy equipment. Tornado is a type of Casing Oscillator to advance. It controls horizontality with 4 cylinders. Those cylinders controlled by high-speed solenoid valves. This paper represents horizontal control of the Tornado using Kinematics. First. the horizontal control simulated by AMESim, which is simulation tool. then it compared with experimental results.

The Spring framework including the MVC design concept is the standard in web development in the JAVA environment. The programming style of the structure must be kept strictly, so every web program is able to employ the same structure. It is convenient to distribute jobs, but there are some side effects, like duplication of code, deterioration of professionalization, and deterioration of program performance. To ameliorate those problems, we propose the horizontality development method(HDM) on Spring MVC. We proved that the HDM can solve the problems through the experiment to keep the MVC structure.

This study investigates the kinetic characteristics of the Driggs motion in horse vaulting by stages through the three-dimensional video analysis of YTY and TABARA who won a high score and a low score respectively from the Driggs motion in horse vaulting during the Daegu Universiade 2003, which involves putting one's hands on the horse vaulting rotating sideways, stretching and rotating backward in the air, and twisting 900 degrees, so as to help develop the techniques of Korean gymnastic athletes. From the analyses of the duration of body center, horizontality, vertical position and horizontality, vertical speed and angle factors for each of four phases from the contact of the board to the takeoff from the horse vaulting. I arrived at the following conclusions: 1. It was found that the motion of bending oneself forward while rapidly stretching the knee joint when taking off from the board increases the horizontal speed of body center and shortens the time of the first jump. 2. It was found that S1 who won a high score shortened the time of the contact and takeoff from the horse vaulting and enlarged the shoulder joint angle for full blocking motion. It was also found that horizontal speed decreased while vertical speed increased when you rapidly stretch the right elbow joint while taking off from the horse vaulting. 3. It was found that horizontal distance was shortened to increase the height and time of staying in the air during the second jump.
