In this paper, a new two dimensional (2D) analytical model of a Dual Material Gate tunnel field effect transistor (DMG TFET) is presented. The parabolic approximation technique is used to solve the 2-D Poisson equation with suitable boundary conditions. The simple and accurate analytical expressions for surface potential and electric field are derived. The electric field distribution can be used to calculate the tunneling generation rate and numerically extract tunneling current. The results show a significant improvement of on-current and reduction in short channel effects. Effectiveness of the proposed method has been confirmed by comparing the analytical results with the TCAD simulation results.

This study tried to examine how interdependence, communication, and the exercise of power in cosmetics distribution channel would affect satisfaction. In this study we investigated the effects of their communication and the exercise of noncoercive power of department store (or mart). We conducted with managers of the shops which were entered to department store (or mart). 131 copies were collected and 119 copies were used for analysis after the exclusion of 12 copies. Brand image and sales policy influenced satisfaction, but customers were not statistically significant. In addition, communication in distribution path had the moderating effect on the relationship between interdependence and satisfaction, and on the relationship between interdependence and noncoercive power. Sales policy and brand image in the relationship between department store(or mart) and the shops opened inside are critical factors for satisfaction, but customers are highly likely to become a factor with different meaning.

An frequency modulated (FM) DANTE pulse sequence generates a quadratic phase toward the transverse of image by an FM RF pulse. In the image of a serious susceptibility effect, the phase due to the difference of the susceptibility in the pixel occurs susceptibility error which arise signal loss. But the signal loss due to the susceptibility effect in the pixel is reduced when the quadratic phase adds in the pixel. In this paper, we have generated a quadratic function toward the transverse (X-Y) using FM DANTE sequence and the susceptibility effect is reduced in the gradient echo (GE) imaging. Computer simulation and experimental results is obtained by using a whole-body KAIS 2.0T NMR system.

This paper reviewed the relationship between internal marketing(management support, education, pay system, internal communication, employment security) and food safety climate(prevention, superior attitude, work condition), and the moderating effect of employment type(permanent or temporary employees) in food service company. Based on the responses from 304 responses, the results of hierarchical multiple regression analysis showed that 4 factors(management support, education, internal communication, employment security) effect positively on food safety climate(prevention, superior attitude, work condition). The positive effect of internal communication on superior attitude and work condition appeared to be more positive in permanent employees than in temporary employees. And the results of t-test analysis showed that permanent employees perceived more positively all internal marketing factors(management support, education, pay system, internal communication, employment security) and food safety climate(precaution, superior attitude, work condition) than temporary employees.

The purpose of this study was to explore the effect of performance of living proprieties on family adaptability and self-esteem, centering on the married men and women residing in the city of Seoul. 220 respondents were randomly selected in July 2000 for the present research. The results of this study were as follows : First, the performance of living proprieties revealed a relatively high level and was shown a significant difference by sex, age, family type, religion, the number of children, experience of propriety education, value orientation, and the degree of communication. Second, family adaptability revealed a relatively high level and was shown a significant difference by family type, experience of propriety education, and the degree of communication. Self-esteem was shown a significant difference by the number of children and degree of communication. Third, background variable (age), the performance of living proprieties (communication manner, family decorum, social etiquette), and family adaptability had a significant effect on self-esteem. This implies that the performance of living proprieties rather than socio-demographic variables has a positive effect on self-esteem.

Despite the ubiquity of mobile phone, the medium has received far less scholarly attention than it should deserve. This study begin with the purpose of fair repositioning of mobile phone in Korean interpersonal communication. To accomplish this purpose, We examined the effect of communication values on perception of mobile phone as interpersonal communication medium, such as the appropriateness and effectiveness of mobile phone. The related raw data were collected from on-line survey process, and statistically analyzed. The result showed that the more effect the traditional communication values of our society have on the perception of mobile phone, the older users are. And Younger generations tend to have more positive attitude to mobile phone as interpersonal communication medium. Particularly when the seniors are interpersonal communication partner and impending task is advice or request, younger persons tend to perceive mobile phone more appropriate and effective than the elder persons do. Thus, it is plausible to predict that relative position of mobile phone will be gradually more important in Koreans' social communication when the younger generation become the mainstream of our society.

This study examined the structural relationships among 4- and 5-year-old children's playfulness, communication skills, and creative characteristics. This research analyzed the direct and indirect influence of child's playfulness on communication skills and creative characteristics. The study subjects were 249 children who attend kindergartens located in the Seoul and Gyeonggi-do area. A survey questionnaire was distributed to the children's mothers and teachers. The sample was analyzed using SPSS 21.0 and AMOS 21.0 program. The parameters were estimated by maximum likelihood method. The significance of indirect effect was tested by bootstrapping at .05 level. The results of this study were: (1) in both ages 4 and 5, playfulness had a direct and positive influence on communication skills, (2) in both ages, communication skills had a direct and positive effect on creative characteristics, and (3) the 5-year-old children's playfulness had a direct effect on creative characteristics, the 4-year-old children's playfulness did not exert direct influence onto creative characteristics. Communication skills 5-year-old children were seen to precipitate a partial mediation effect between playfulness and creative characteristics. At age 4, communication skills played a full mediation variable role between playfulness and creative characteristics. Discussions include suggestions to prosper creative characteristics through enhancing a child's playfulness and communication skills.

The purpose of this study was to objectively explore and discuss the effect of trainer's communication style on rehabilitation ability and rehabilitation satisfaction of elite athletes. we observed the relationship between rehabilitation trainers and injured athletes and found that communication between them plays an important role. In this study, we criticized that most of the studies related to rehabilitation were conducted from the point of view of natural science. The results of this study emphasized that rehabilitation-related research should broadly accept social science positions such as business administration. The main research findings are as follows. As a result of analyzing the relationship between trainer's communication style and rehabilitation ability, first, the trainer's cooperative and professional communication style affects emotional factors of injured players. Second, the trainer's cooperative and controlled communication style affects the cognitive factors of injured players. Third, the trainer's cooperative and professional communication style affects the behavioral factors of injured players. Fourth, the trainer's cooperative and professional communication style affects the rehabilitation satisfaction of injured players. Based on these results, this study was conducted to validate the necessity of discussing the trainer's communication style preference according to the individual background such as the injured player's gender, personality, and injury level, and the classification and composition of communication styles that match Korean culture and sentiment. As suggestions for follow-up research, active sharing of problems with adjacent disciplines such as sports sociology, sports education, and sports marketing, and parallel qualitative research centered on individual cases were suggested
