The analysis of the customers' mind is crucial in the modern society where marketing strategy is very important for the satisfaction of the customers. the purpose of this study was investigating the relationship between lifestyle characteristics and service satisfaction of sports center customer. To achieve this purpose, the population of this study are the participants of the swimming pool, bowling center, fitness club and golf club among the commercial sports center in Jeonju, Jeollabugdo. They are chosen by the multi-stage stratified random sampling considering the events and region. The valid samples are 420 persons at last among 500 persons except the 80 persons whose validity are determined low. To analyze the data, frequency analysis, factor analysis, t-test, ANOVA, regression analysis and covariance structural analysis are used in this study. In this study, those following results are gathered by analysing the data through above approaches. First, According to the background variation of the sports participator; material service to income, personal service to educational level and occupation, systematic service to sex and educational level, there are significant service satisfactions. Second, Lifestyle characteristics of the sports participator influence on service satisfactions significantly; persuit of the trend, social contact, nervousness and individualism influence on personal service social contact, persuit of the trend, nervousness and sentimentalism on systematic service and the other variations on material service.

We developed a dietary supplement using natural herbs and nutrients for the growth and exercise performance improvement. It called JR-22 supplement containing distilled extracts of natural herbs to remove bitterness and the addition of Vitamin B1, B6, Ca and xylitol. We investigated on the effect of JR-22 supplementation on the maximal exercise performance, IGF-1 (insulin like growth factor-1) concentration and antioxidant activity in SD rat model. In result, JR-22 supplement group was better than control group about 10% in exercise performance test and increased about 63% of IGF-1 concentration in blood. In addition, the oxidative damage induced by exercise was reduced by JR- 22 supplementation. Therefore, we suggested that JR-22 supplementation enhanced effectively exercise performance and IGF-1 concentration and reduced to oxidative stress in muscles. Also, we analysed biochemical factors in blood for the safety of JR-22 supplement. We known that there is no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity.

In this paper, we propose a system to predict the GPS trajectory of a pedestrian based on a deep learning model. Pedestrian trajectory prediction is a study that can prevent pedestrian danger and collision situations through notifications, and has an impact on business such as various marketing. In addition, it can be used not only for pedestrians but also for path prediction of unmanned transportation, which is receiving a lot of spotlight. Among various trajectory prediction methods, this paper is a study of trajectory prediction using GPS data. It is a deep learning model-based study that predicts the next route by learning the GPS trajectory of pedestrians, which is time series data. In this paper, we presented a data set construction method that allows the deep learning model to learn the GPS route of pedestrians, and proposes a trajectory prediction deep learning model that does not have large restrictions on the prediction range. The parameters suitable for the trajectory prediction deep learning model of this study are presented, and the model’s test performance are presented. 본 논문에서는 딥러닝 모델 기반 보행자의 GPS 경로를 예측하는 시스템을 제안한다. 보행자 경로 예측은 보행자의 위험 및 충돌 상황들을 알림을 통해 방지할 수 있으며, 다양한 마케팅 등 비즈니스 면에서도 영향을 끼치는 연구이다. 또한 보행자 뿐 아니라 많은 각광을 받고 있는 무인이동수단의 경로 예측에도 활용될 수 있다. 다양한 경로 예측 방식들 중 본 논문은 GPS 데이터를활용하여 경로를 예측하는 연구이다. 시계열 데이터인 보행자의 GPS 경로를 학습하여 다음 경로를 예측하도록 하는 딥러닝 모델 기반 연구이다. 본 논문에서는 보행자의 GPS 경로를 딥러닝 모델이 학습할 수 있도록하는 데이터 셋 구성 방식을 제시하였으며, 예측 범위에 큰 제약이 없는경로 예측 딥러닝 모델을 제안한다. 본 연구의 경로 예측 딥러닝 모델에 적합한 파라메터들을 제시하였으며, 우수한 예측 성능을 보이는 결과를 제시한다.

Brake judder caused by disc runout and disc thickness variation was investigated. Experimental data shows that disc runout and disc thickness variation are influential source of so called cold judder. Judder amplitude is proportional to vehicle speed and brake pedal operation speed. Judder frequency is directly related to rotational speed of brake disc and the number of poles of periodic distribution of disc runout and disc thickness variation, but there is no relationship between judder frequency and natural frequency of brake disc.

EU and CARB demand more stringent emissions regulations and OBD functions of components emitted harmful emission. It also demands that MIL is light-on to inform the failure to the driver when the converter is failed in its function. Usually dual oxygen sensor method is used for converter OBD monitoring. However, introduced methods for converter monitoring are applied higher temperature than light-off temperature and give poor resolution between OBD index and emissions to meet LEV II programs.<br/> In this study, OSCs of aged and fresh converters are investigated with an absolute measuring method and dual oxygen sensor methods at lower temperature than light-off temperature. As dual oxygen sensor methods, amplitude ratio method and time delay method were examined. The relationship between absolute OSC and amplitude ratio is evaluated as a function of converter inlet temperature. The temperature which can give a good resolution for converter monitoring is suggested. Also, the relationship between absolute OSC and time delay is represented.<br/>

The components affecting the extrinsic transconductance (g<sub>m_ext</sub>) in In<sub>0.7</sub>Ga<sub>0.3</sub>As quantum-well (QW) high-electron-mobility transistors (HEMTs) on an InP substrate were investigated. First, comprehensive modeling, which only requires physical parameters, was used to explain both the intrinsic transconductance (g<sub>m_int</sub>) and the g<sub>m_ext</sub> of the devices. Two types of In<sub>0.7</sub>Ga<sub>0.3</sub>As QW HEMT were fabricated with gate lengths ranging from 10 μm to sub-100 nm. These measured results were correlated with the modeling to describe the device behavior using analytical expressions. To study the effects of the components affecting g<sub>m_int</sub>, the proposed approach was extended to projection by changing the values of physical parameters, such as series resistances (R<sub>S</sub> and R<sub>D</sub>), apparent mobility (μ<sub>n_app</sub>), and saturation velocity (v<sub>sat</sub>).
