고객의 만족을 극대화하기 위해서는 서비스 전달에서 발생할 수 있는 오류를 최소화하여 서비스 가치를 창출하는 것이 중요하다. 이에 다양한 직무경험은 고객의 서비스 극대화뿐만 아니라 개개인의 경력개발에도 큰 도움이 된다. 또한 기업들과 조직관리 측면에서도 우수인력 개발을 위한 주요 수단으로 사용되어지고 있다. 하지만 호텔종사원의 직무순환이 고용경쟁력과 주관적 경력만족에 미치는 영향의 구조적 관계에 관한 연구는 아직까지 미흡한 실정이다. 해서 본 연구를 위해 특 1,2급 호텔에 근무하는 직원을 대상으로 설문을 실시하였으며 총 370명의 자료가 실증분석에 사용되었다. 직무순환, 고용경쟁력, 주관적 경력만족의 구조적관계를 분석한 결과, 직무순환은 고용경쟁력 및 주관적 경력만족도에 유의한 영향을 미쳤다. 그리고 직무순환과 주관적 경력만족에서 고용경쟁력이 부분적으로 매개효과가 있는 것으로 나타났다. 따라서 호텔종사원의 지각된 직무순환을 통한 고용경쟁력의 효과로 개인과 조직 모두를 위한 올바른 경력개발 및 경력관리 프로그램을 활용하여 호텔을 포함한 환대산업에 실질적 도움이 되는 것이 본 연구의 주된 목적이다.

The purpose of this study was to determine the effect of Pilates Reformer training on gait improvement of subjects with asymmetric pelvic rotation. The seven subjects with greater pelvic rotation in right swing were assessed twice, 4 weeks apart, during which there was submitted to a Pilates Reformer training (three 40 min session per week). The kinematic data consisted of pelvic rotation and flexion angle of hip and knee joint was measured during gait. In comparison between both leg swings, max, min and range values of pelvic rotation was not significantly difference. After training, range of pelvic rotation in right swing was significantly decreased, but in left swing was not. In comparison between both leg swings, the values of max of hip and knee joint angle was significantly difference. After training, max values of angle of knee joint in right swing was significantly increased, but in left swing was not. The result of this study revealed that Pilates Reformer training was effective in improving gait to symmetric pelvic rotation.

Purpose : The purpose of this study was to investigate the effect of tensor fasciae latae length on the rotation of pelvis during one leg stance. Methods : 41 healthy adults participated in this study. The movement of the pelvis and trunk was measured using 3-dimensional motion analyzer, during one leg stance. The movement of the pelvis and trunk was collected lateral shift, rotation, side bending, and flexion-extension. Tensor fasciae latae length of subjects was measured in sidelying positon with neutral position of hip joint and flexion $90^{\circ}$ of knee. Also, the range of motion of hip exteral and interal rotaion were measured in prone position wih lexion $90^{\circ}$ of knee. The subjects were separated 2 groups that more pelvic rotation group(n=15) and less pelvic rotation group(n=15) according to the degree of pelvic rotation. Results : The more pelvic rotation group was showed significantly higher in the ROM of hip external rotation than less pelvic rotation group(p<0.05). The difference of tensor fasciae latae length not showed significant difference between groups. During one leg stance, The movement of the shifting and flexion-extension of trunk and pelvis were not showed significant difference. But the side bending and the rotation of pelvis and trunk showed significant difference between groups. Conclusion : The difference of tensor fasciae latae length not showed significantly in more pelvic rotation group and less pelvic rotation group. But, this study suggests that the pelvis instability brings the instability of the trunk during one leg stance.

Pulfrich 효과는 운동정보를 처리하는 기제가 깊이정보도 처리할 가능성을 시사하는데, 다양한 신경생리학적 결과들이 이러한 가능성을 지지한다. 대표적인 깊이정보인 양안부등을 처리하는 기제가 Pulfrich 효과도 처리할 것이라는 가능성이 제기되어 왔지만, 두 가지 정보원이 하나의 자극 내에 공존하는 경우에 두 정보원의 상호작용 특성을 규명하기 위한 정신물리학적 연구는 없었다. 본 연구는 양안부등과 Pulfrich 효과를 이용하여 회전하는 무선점 반투명 원통체의 회전반향과 깊이를 일관되게 (일치조건) 또는 일관되지 않게 정의하는 조건 (불일치 조건)에서의 원통체의 지각된 깊이와 회전방향을 측정하였다. 일치조건에서 지각된 원통체의 깊이는 양안부등 또는 Pulfrich효과 단독에 의하여 정의된 원통체의 지각된 깊이보다 컸다. 흥미롭게도 불일치 조건에서 원통체의 지각된 회전방향은 양안부둥과 Pulfrich효과의 상대적인 강도에 의하여 조절되었다. 이러한 실험결과는 양안부등과 Pulfrich효과가 하나의 처리기제를 공유함을 함의한다.

Objective: This study aims to analyze job satisfaction and accident prevention according to job rotation system types in a motor company. Background: The study of a motor company's job rotation system has come to attention with enhancing productivity, preventing musculoskeletal disorders, and improving quality. Method: In this study, a survey was conducted to show job satisfaction rates according to job rotation systems. Also an investigation was done regarding industrial accidents and previous workers who are receiving treatment for musculoskeletal disorder over the last five years. Results: The job rotation system in this study has been carried out by voluntary decision of workers. Out of the job rotation types, the medium rotation complexity type had high job satisfaction whereas in a high or low rotation complexity type, which many workers prefer, led to less number of accidents and days of sick leave. Application: The results of this study are expected to be a fundamental data to job design.

Background: The serratus posterior inferior (SPI) muscle originates from the spinous process of T11-L2 and inserts at the lower border of the 9-12th ribs. This muscle is involved in thoracolumbar rotation and stability. Several positions can be used to improve trunk stability; the quadruped position is a good position for easily maintaining a neutral spine. In particular, during one arm lifting, various muscles act to maintain a neutral trunk position, and the SPI is one of these muscles. If trunk stability is weakened, uncontrolled trunk rotation may occur at this time. Tape can be used to increase trunk stability. There have been no studies on the effect of taping applied to the SPI muscle on thoracolumbar junction (TLJ) stability. Objects: This study compared the TLJ rotation angle between three different conditions (without taping, transverse taping, and SPI muscle direction taping). Methods: Thirty subjects were recruited to the study (18 males and 12 females). The TLJ rotation angle was measured during one arm lifting in a quadruped position (ALQP). Two taping methods (transverse and SPI muscle direction taping) were applied, and the TLJ rotation angle was measured in the same movement. Results: SPI muscle direction taping significantly reduced TLJ rotation compared to that without taping (p < 0.001) and with transverse taping (p < 0.001). There was a significant difference in the TLJ rotation angle between transverse taping and SPI muscle direction taping (p < 0.017). Conclusion: SPI muscle direction taping reduces the TLJ rotation angle during ALQP. Therefore, SPI muscle direction taping is one method to improve TLJ stability and reduce uncontrolled TLJ rotation during ALQP.

A corona motor, as one of a powerful cooling means of microelectronic devices, has been employed because of its very simple structure of no coils and no brushes. In this paper, the effect of polarity of applied voltage and the number of blade corona electrodes on the fundamental properties of rotation of the motor was investigated. The I-V and rotation characteristics of the blade corona electrode were significantly different from the different polarities of applied voltages and the blade corona electrode numbers, due to the different space charge effect resulted by the different migration mobility of the positive and negative ions generated near the blade corona electrode tip of the rotor of the motor. The rotation speed of the motor was influenced significantly by the polarity of corona discharge, the number of blades, and mass of rotor. At the same corona current, an effective rotation can be obtained with the positive corona caused by the lower ion mobility. On the other hand, the higher rotation speed can be obtained with the negative corona resulted from its higher corona current. The highest rotation speed and energy efficiency can be obtained with the rotor having 4 blades.

Rotational motion in the atmosphere around a fire may have a profound influence on the fire plume. This process underlies the occurrence of fire whirls. Fire whirls are rare but highly destructive phenomenon which were observed in a large forest, urban and building fires. The present study aims to investigate of the effect of rotation Strength on the fire whirl characteristics expeimentally. Experiments are performed for various sizes of fire source with different rotation strength. From the experimental observations, it is noted that the mean centerline temperature is gradually increased and mean radial temperature is decreased as increases rotation strength. The characteristic mean flame height of fire based on the visible observation is increased as increases of dimensionless swirl parameter, $\Omega/\alpha$, represented by swirl induced motion to buoyancy driven motion.
