MTJ devices are fabricated using metal shadow masks and switching characteristics are investigated under 2 dimensional magnetic field. When the hard axis field is less than $\pm$ 16 Oe, switching behavior is similar to that based on the Stoner-Wohlfarth model. As the hard axis field is larger than $\pm$ 16 Oe, deviation from the expectation by Stoner-Wohlfarth model is observed. These phenomena are induced by the generation of multi-domain and inhomogeneous magnetization reversal.

This study aimed to investigate the influence of consumers' innovativeness, perceived benefits of home shopping mobile apps, and satisfaction with telephone orders on switching to and satisfaction with such apps (for those who have used these apps). This study also investigated the influence of the aforementioned factors on the intention to switch to home shopping mobile apps (for those who have not used these apps). Data were collected from 546 customers ranging in age from 18 to 59 with experience purchasing fashion goods from home shopping networks, and 502 of the questionnaires were used in the statistical analyses. Structure equation models were employed using AMOS 23.0. The results were as follows: for consumers experienced with home shopping mobile apps, their innovativeness and perceived benefits of such apps (convenience, usefulness) influenced their switching behavior. Additionally, consumers' innovativeness and perceived benefits of these apps (usefulness, accessibility, interactiveness) affected their satisfaction with the apps. For those not experienced with home shopping mobile apps, consumers' innovativeness and perceived benefits of the apps (interactiveness, security, enjoyment) influenced their intention to switch to these apps. These results indicate that different strategies should be developed for home shopping consumers experienced and inexperienced with these apps for the improvement of app satisfaction.

We proposed amorphous GeSe-based ReRAM device of metal-insulator-metal (M-I-M) structure. The operation characteristics of memory device occured unipolar switching characteristics. By introducing the concepts of valance-alternation-pairs (VAPs) and chalcogen vacancies, the unipolar resistive switching operation had been explained. In addition, the current transport behavior were analyzed with space charge effect of VAPs, Schottky emission in metal/GeSe interface and P-F emission by GeSe bulk trap in mind. The GeSe ReRAM device of M-I-M structure indicated the stable memory switching characteristics. Furthermore, excellent stability, endurance and retention characteristics were also verified.

Variable structure control (VSC) systems control the state vectors using sliding regime (SR) constructed switching logic, switching plane and control law. Saturation function switching logic is used to improve the drawback which occurs in traditional sign function switching logic. Switching plane with time-varying parameter is proposed to improve the drawback which occurs in switching plane with constant parameter and it is suggested the control law which has time-varying parameter. The stability of VSC system controlled by proposed time-varying SR is discussed, and the good control behavior was shown through computer simulation using proposed SR.

This study obtains information required for a comprehensive understanding of the brand-switching behavior by cosmetics consumers and for the establishment of effective strategies to make customers more loyal to the company. The study examines the relationships between customer shopping orientation and brand switching motives with respect to cosmeceuticals. A descriptive survey method using a self-administered questionnaire was employed. The sample consisted of 1,258 females between the ages of 20's and 30's residing in Seoul and the Gyeonggi area who use whitening products, sunscreen, or other anti-aging cosmetics. The results showed that shopping orientation influenced brand-switching motives in regards to purchasing cosmeceuticals. The orientation of depending on information and seeking fashion trend were the major factors to induce brand-switching behavior in purchasing whitening products, sunscreen, and anti-aging treatments. However, there were differences in the type of factors of shopping orientation and in their intensity of affecting brand-switching motives depending on the specific cosmeceuticals. In particular, in the case of sunscreen, as compared to other products, the customer shopping orientation should be considered from more diverse perspectives in order to formulate effective marketing strategies related to brand switching. In light of these results, customer shopping orientation with respect to cosmeceuticals is a variable that influences the cause brand switching. Therefore, differentiated marketing strategies that reflect the different characteristics of shopping orientation according to each item of cosmeceuticals are recommended to improve the satisfaction level of the companies' target market. Current consumer needs for practical benefits and for new products should be simultaneously reflected in the plans for new product development of each type of cosmeceutical.

The purpose of this study was to investigate the The effect of fashion consumer's need for uniqueness in their clothing purchase behavior and switching intention. A total of 332 cases were included as the subjects of this study and a survey method was used. The data were analyzed by factor analysis, reliability analysis, t-test and multiple regression analysis using the SPSS 22.0 statistical program. The results were as follows. 1. The 3 dimensions (creative choice, unpopular choice, and avoidance of similarity) were extracted from the consumer's need for uniqueness and consumer divided high uniqueness group, middle uniqueness group, low uniqueness group. 2. The 3 factor (esthetic, functional, practical) were extracted from the clothing selection criteria. The three group had a significant difference in clothing selection and switching intention. Aesthetic factor and practical factor were the highest in high uniqueness group. 3. The need for uniqueness has influence on the aesthetic factor and practical factor. The creative choice factor had positive effect on the aesthetic and practical factor, yet unpopular choice factor had negative effect on the practical factor. The need for uniqueness and aesthetic factor has positive influence on brand switching intentions. 4. There was difference in unpopular choices factor by gender. A monthly average expenditure on fashion products had a significant difference in three kind of need for uniqueness. Results of this study provide a basis understand need for uniqueness and their effect on consumer behavior.

The purpose of this study is to highlight the importance of relationship marketing which has been developed as an alternative way of handling marketing in family restaurants. This study focused on the consumers' behavior - mainly their switching behavior and loyalty toward relationship marketing activities exercised by from family restaurants. 269 usable questionnaires were collected from customers patronizing three family style restaurants in Seoul. Several statistical methods were used including descriptive analysis, reliability test, covariance analysis, confirmatory factor analysis, and covariance structural analysis. The result drawn from empirical test proved that relationship marketing activities actually are the significant determinants of relationship quality and thus to the customers' behaviors toward the restaurants they patronize. Managerial implications can be drawn from the result findings that restaurant companies can identify the activities of relationship marketing to continue the long-term relationship with their customers. Also restaurant companies can use the activities of relationship marketing as differentiating strategies, and allocate their resources into the activities of relationship marketing.

We investigated electrical conduction and resistance switching behavior of the Ag/ZnO/Ti structures for random access memory devices. These films were prepared on glass substrate by dc sputtering technique at room temperature. The resistance switching follows unipolar switching mode with small switching voltages (0.4 V - 0.6 V). Two electrical conduction mechanisms dominating the LRS and HRS are Ohmic and trap-controlled space charge limited current, respectively. These both conductions are consistent with the filamentary model. Based on the filamentary model, the switching mechanism was also interpreted.
