In this letter, we propose the use of tunneling field effect transistors (TFET) as a biosensor that detects bio-molecules on the gate oxide. In TFET sensors, the charges of target molecules accumulated at the surface of the gate oxide bend the energy band of p-i-n structure and thus tunneling current varies with the band bending. Sensing parameters of TFET sensors such as threshold voltage ($V_t$) shift and on-current ($I_D$) change are extracted as a function of the charge variation. As a result, it is found that the performances of TFET sensors can surpass those of conventional FET (cFET) based sensors in terms of sensitivity. Furthermore, it is verified that the simultaneous sensing of two different target molecules in a TFET sensor can be performed by using the ambipolar behavior of TFET sensors. Consequently, it is revealed that two different molecules can be sensed simultaneously in a read-out circuit since the multi-sensing is carried out at equivalent current level by the ambipolar behavior.

The purpose of this study was to examine the consumers' purchasing behavior of budget-priced cosmetics according to the shopping orientation. Questionnaires used for this study were composed of 57 questions including 21 questions about cosmetic shopping orientation, 32 questions about budget-priced cosmetic purchasing behavior and four questions about demographic variables. Questionnaires were administrated to 20 to 49 aged 317 women who have shopping experience on budget-priced cosmetics. Data were analyzed by using factor analysis, cluster analysis, ANOVA, ${\chi}^2$-test, correlation, crosstabulation analysis, and scheffe test utilizing SPSS/WIN. The results were as follows. First, shopping orientation of cosmetics were classified into 5 factors: 'interest and impulsive purchasing tendency', 'price-oriented purchasing tendency', 'ration-oriented purchasing tendency', 'famous brand-oriented purchasing tendency' and 'brand royalty- oriented purchasing tendency'. According to the shopping orientation of cosmetics, the respondents were classified into 4 groups: 'passive shopping group', 'rational shopping group', 'active shopping group', 'neutral shopping group'. Second, when comparing each group's purchasing behavior of budget-priced cosmetics with shopping orientation of cosmetics, there was not significant difference in one time purchasing cost and the number of shop visits. In case of demographic variables concerning purchasing behavior of budget-priced cosmetics, there was significant differences in one time purchasing cost according to age, level of education and employment status. The number of shop visits had also difference according to age, level of education and monthly family income. Based on these results, marketing strategies for demographic characteristics of target market rather than the shopping orientation are needed.

In China, the phenomenon called 'Korean Wave' has boosted the interest in Korean pop culture, such as TV drama, music and films, and even in the general culture and society. As Korean singers, movie actors and talents become popular beyond acceptance of public culture, those who learn Korean, buy Korean products and visit Korea have emerged. Especially, most Chinese women have used Korean hair cosmetics and the interests in Korean hair cosmetics are increasing, since cosmetic companies entered China early due to Korean wave. Thus, the status of purchase of Korean hair cosmetics is growing day by day in China. In particular, since the environment is established to buy hair cosmetics easily in Myeong-dong which is one of the shopping tourism special districts, many Chinese tourists are crowded there. Based on such phenomenon, this study explored the differences in perceptions towards 'Korean Wave' among Chinese tourists who purchased Korean hair cosmetics in Myeong-dong, and analyzed the factors that largely determine the interest in Korean hair cosmetics and their purchase behavior. Therefore, this study is aimed at contributing to the development of hair cosmetics products and the market amid Korean Wave. As the research methods, 100 answered questionnaires were collected with target of Chinese tourists at 20s and 40s who purchased Korean hair cosmetics in Myeong-dong once 120 questionnaires were distributed. In-depth analysis was conducted and final research data were used. It was confirmed that Korean fever positively affected the Chinese tourists' purchase behavior and satisfaction of hair cosmetics, and the interests in Korean hair cosmetics at 20s were higher than at 40s. People at 20s had higher awareness, satisfaction and intention of repurchase of hair cosmetics compared rather than people at 40s. The research confirmed that Chinese tourists are very interested in Korean hair cosmetics as the pop music craze has led to the general Korean Wave, and differences in such perceptions have led to significant differences in the product purchase behavior.

Purpose : The purpose of this study was to systematically review the studies on the effects of social story intervention on the individuals with autism spectrum disorders(ASD) to provide the basis for evidence-based practice. Methods : In order to find out the studies on the effect of social story intervention on individuals with ASD, studies published from 2011 to December 2020 were searched on Google Academic Search. The keywords used were "autism spectrum disorder AND social story". A total of 16,900 studies were searched, and from these, 12 studies were selected based on the application of the selection and exclusion criteria. The included studies comprised of 10 single subject design studies and 2 randomized controlled trials design studies. The included studies were analyzed in accordance to population, intervention, outcome measures and results. Results : As a result of analysing the subjects of the included studies, we found out that pre-school children and adolescents were the most common groups of individuals diagnozsed with ASD. In addition to ASD, the diagnosis of the subjects included intellectual disability, Asperger, and Prader-willi. We found out that there were more interventions that were mixed with other interventions, than just the pure social story interventions. In particular, video modeling was found to be the most frequent intervention. This was followed by photo-based social stories. For outcome measure, autism social skills profile was found to be the most often used standardized assessment. For a non-standardized assessment, social desired behavior was found to be the most frequently evaluated behavior, followed by personal problem behavior. Of all the dependent variables, the dependent variable reported as "effective" was the most, followed by "some effective". Conclusion : This study is organized to help the individuals with ASD, families, researchers, and therapists understand the effects of social story intervention on the individuals with ASD in an easy fashion. Further, therapists can use this study as the basic data for evidence-based practice.
