The purpose of this study was to lay emphasis on the importance of a restaurateur's role and qualities as well as to provide the restaurateur information necessary to effectively run a restaurant. To address the purpose, this study analyzed the qualities of a restaurateur and determined the influence they have on the business results, via conducting a survey with 117 restaurateurs from June 11th to June 26th 2011. In summary, male restaurateurs were higher in the vision directivity, desire to learn, accomplishment, challenge and pro-activity than their female counterparts, with a significant difference of p<0.05. According to their ages, the surveyees showed significant differences in the vision directivity (p<0.05), desire to learn (p<0.01), challenge (p<0.01) and pro-activity (p<0.01). In addition, also the survey revealed that the qualities of a restaurateur had a significant influence on financial performance, a sense of satisfaction and business results (p<0.001). The questionnaire resulted in the following: first, the vision directivity (p<0.05) and the challenge (p<0.05) affected the financial performance; second, the challenge had influence on the sense of satisfaction; and last, the vision directivity (p<0.05) and the challenge (p<0.05) had an effect on the business results. Thus, the study concluded that restaurateurs need two qualities: (i) the vision directivity in order to meet their goals and to have a higher business results and (ii) the challenge to try new managing methods in order to cope with the ever-changing environment.

In this paper, we present an analytical model for the first eigen energy level ($E_0$) of the carriers in the inversion layer in present generation MOSFETs, having ultrathin gate oxides and high substrate doping concentrations. Commonly used approaches to evaluate $E_0$ make either or both of the following two assumptions: one is that the barrier height at the oxide-semiconductor interface is infinite (with the consequence that the wave function at this interface is forced to zero), while the other is the triangular potential well approximation within the semiconductor (resulting in a constant electric field throughout the semiconductor, equal to the surface electric field). Obviously, both these assumptions are wrong, however, in order to correctly account for these two effects, one needs to solve Schrodinger and Poisson equations simultaneously, with the approach turning numerical and computationally intensive. In this work, we have derived a closed-form analytical expression for $E_0$, with due considerations for both the assumptions mentioned above. In order to account for the finite barrier height at the oxide-semiconductor interface, we have used the asymptotic approximations of the Airy function integrals to find the wave functions at the oxide and the semiconductor. Then, by applying the boundary condition at the oxide-semiconductor interface, we developed the model for $E_0$. With regard to the second assumption, we proposed the inclusion of a fitting parameter in the wellknown effective electric field model. The results matched very well with those obtained from Li's model. Another unique contribution of this work is to explicitly account for the finite oxide-semiconductor barrier height, which none of the reported works considered.

Purpose: The ultimate purpose of this work is to investigate gender differences in the relationships between product quality cues and perceived values at a food select shop. Specifically, this study examines the effects of internal and external cues, which are indicators of product quality, on emotional and social values based on gender differences. Research design, data and methodology: In this study, a questionnaire technique was used to collect the data necessary to test the proposed model. 183 data were collected through this technique. PLS SEM (Partial Least Squares Structured Equation Model) was used to test the research model. Results: First, there is no gender difference between intrinsic cue and emotional value. When using male and female data, there was no significant causal relationship between intrinsic cues and emotional values. Second, we found no gender difference between intrinsic cue and social value. When analyzed with female data, there was no significant causal relationship between intrinsic cue and social value. On the other hand, in the case of men, it was found that a weak causal relationship exists. Third, this study found gender difference between extrinsic cue and emotional value. In the case of men, it was found that a weak causal relationship exists, whereas in the case of women, a strong causal relationship exists between extrinsic cue and emotional value. Fourth, we found gender difference between extrinsic cue and social value. In the case of men, there was no causal relationship, whereas in the case of women, there was a strong causal relationship between extrinsic cue and social value. Finally, we found that there are moderating roles of gender in the relationship between external cues and perceived quality. Conclusions: As a result of analysis, it is necessary to focus on extrinsic clues of product in order to increase the perceived emotional and social values of women. On the other hand, in order to improve the perceived emotional and social values of men, it is necessary to pay attention to both intrinsic and extrinsic cues of product. Therefore, it is necessary to consider what clues and values are important to core customers.

Purposes: This study was to analyze the effects of organizational culture attributes on organizational effectiveness in newly established general hospital. Method: For this purpose, this study sampled 981 hospital employees working for E hospital opened on Apr. 1, 2019 in Seoul. A total of 981 questionnaires were distributed to them, and 888 ones responded to the survey, which had been conducted from Oct. 17, through Oct. 25, 2019. 793 responses were used for the final analysis. The data collected were processed using the SPSS 19.0K for descriptive statistics, T-test, ANOVA, Pearson's correlation coefficient and regression analysis. Findings: First, The type of organizational culture perceived most by hospital employees was 'hierarchy-oriented' (3.53) followed by 'relation-oriented'(3.33), 'task-oriented'(3.23), 'innovation-oriented'(3.19) and job satisfaction scored 3.13, organizational commitment scored 3.28 on their order. Second, 'Relation-oriented', 'task-oriented' and 'innovation-oriented' was positively correlated with job satisfaction and organizational commitment. hierarchy-oriented' was negatively correlated with job satisfaction and organizational commitment. Third, Factors that significantly influencing on organizational effectiveness in a newly established general hospital were as follows. Factors influencing job satisfaction included 'innovation-oriented', 'relation-oriented' and factors influencing organizational commitment included 'relation-oriented', 'innovation-oriented' and age. Practical Implications: In order to increase the organizational effectiveness of the E-General Hospital, it is necessary to gradually move from a hierarchica l-oriented culture to an innovation-oriented and relationship-oriented culture. Since age also affects organizational commitment, it is necessary to promote stability and growth by promoting the mentor-menti system for new members with a low level of experience and experience.
