The adsorption configurations of S-proline on Ge(100) were studied using scanning tunneling microscopy (STM), density functional theory (DFT) calculations, and high-resolution core-level photoemission spectroscopy (HRCLPES). We identified three adsorption structures of S-proline on Ge(100) through analysis of the STM images, DFT calculations, and HRCLPES results: (i) an 'intrarow O - H dissociated and N dative bonded structure', (ii) an 'O - H dissociation structure', and (iii) an 'N dative bonded structure'. Moreover, because adsorption through the N atom of S-proline produces a new chiral center due to symmetry reduction by N dative bonding, the adsorption configurations have either (R,S) or (S,S) chirality, yielding an (R,S)-'intrarow O - H dissociated and N dative bonded structure' and an (R,S)-'N dative bonded structure', with a preference for reaction at the Re face. This work presents a novel method for generating stereoselective attachment using S-proline molecules adsorbed onto a Ge(100) surface.

This study examines the effects of celebrity endorsed advertising from a new perspective of the prior research that emphasizes the matchup between the brand and the celebrity. Due to the recent sharing experiences of the celebrity and their fans on SNS, it is hypothesized that the shared stories would impact viewers' responses that are often expressed in their likes, dislikes, shares and comments on SNS. In this study, the episodic type of advertising is hypothesized to have more favorable and active responses from viewers than the typical celebrity image-focused ads would have. By crawling and analyzing viewers' responses on YouTube toward 12 BTS endorsed ads, the hypotheses are confirmed as higher ratio of likes, lower ratio of dislikes and significantly higher ratio of comments over both total views and total likes were found. For the rationale behind, total 1800 comments were categorized into 4 major content types such as attached, experiential, empathic and self-related ones that are all considered as important factors influencing the strong ad effect. The results showed that the episodic ads have marginally more emotional comments than the celeb image ads. The difference was only found in experiential and empathic responses but not in self-related responses. Contrary to the hypothesis, the comments expressing attachment were found more for the celebrity image-focused ads than the episodic ones. It does not seem to suggest that the celebrity image focused ads are better to capture viewers' attachment towards the celebrity and the ad endorsed, but that the episodic ads draw viewers into relatively deeper level of attachment such as empathy by perceiving the authenticity of the celebrity and the brand. In conclusion, the shared stories on SNS can be a factor in the match-up theory on celebrity endorsed ad effects.

In this paper, it is to identify the effects of differences in interpretation levels depending on the type of brand association and the brain psychological distance on the evaluation of the product of that brand through two experiments. To test our hypotheses empirically, we conducted online survey. We addressed the hypotheses involving the general and relative impact of actual and ideal self-congruence on emotional brand attachment (H1) and explored the effect of product involvement as the moderating variable (H1-1 and H1-2). The goal of this research was to validate the results from involving our basic model and to explore the impact of two additional moderating variables (self-esteem and public self-consciousness: H2). We followed the same procedure. This finding is theoretical to the extent of the interpretation level theory in brand association research by applying the interpretation level theory to the brand association, and provides the meaning that, in practice, it is necessary to utilize the message of different types of brain psychological distance depending on the brand association characteristics that the brand has in defining the brand. In particular, it was confirmed that functional brand associations and symbolic brand annals have representational harmonization, respectively, depending on the low and high levels of interpretation levels.

Purpose: This research was conducted to explore the experience of middle-aged women parting with their children and to develop a grounded theory. Method: The participants were 11 women in their 50's who had experienced parting with their children due to schooling, military service and marriage. The grounded theory methodology based on symbolic interactionism was used. Results: 106 concepts, 30 subcategories and 14 categories were derived from the analysis through processes of open coding, axial coding and selective coding. The central phenomenon was 'happy but sad' and the core category was a process of 'independence that is sorrowful yet delightful'. Four types were identified; the independent-type; submissive -type; family-reliant-type ; and fragile-type; based on the attachment to the child, state of mind, satisfaction of the situation, family support system and self-achievement. Conclusion: This research identified that the modern Korean middle-aged women who are considered to be the 'sandwich generation' since they have experienced a turbulent history and the change from a confucian parent-child lifestyle to a couple-oriented one, moved away from an attitude dependent on children in parting with them and started preparing for an independent late life. Based on the results, the verification research is advised on the variables that affect the experience of parting with children.

Purpose: This study was done to provide a basis for future theory development by analyzing the phenomenon of parent-child relationships based on the 4 areas described by Kim (2000). Methods: A descriptive research design was used to identify research trends in nursing related to the phenomenon of parent-child relationships. Results: Before 1990, the trend in research design was quantitative designs, but since 1990, qualitative research has also been done. Mothers were the most popular research target for these studies followed by mothers and children together. In analyzing the 4 areas outlined by Kim (2000), it was found that most of the research was done on client domain and parents. The research concepts relevant to the essentialistic concept of research target, were 'child rearing', 'breast-feeding' and 'attachment'. For problematic concepts, the concept of 'stress' was continuously dealt with over the period and for the health-care experiential concept, 'adjustment' and 'coping' by parents were the main focus of research. Conclusion: The results show that parent-child relationship research was mainly concentrated on research participants and concepts. In the future, improvements should be made in research development of nursing practice programs and development of theory, to address the complete phenomenon of parent-child relationships.

The purpose of study was to analyze the process of accepting by BTS fans. The methodology used in this study was qualitative research using grounded theory and the results of the study follow. As a result of open coding, 47 concepts, 23 subcategories, and 14 categories were derived. In the axis coding stage, the casual conditions were "Recognition of BTS image," "Fascinated by BTS image," "Simple consumption of BTS image," and "Arising and expansion of curiosity about BTS image." The contextual conditions were "Accessibility of BTS image" and "Abundance of BTS image searching paths." The central phenomenon appeared to be "Immersing and studying BTS image." The arbitration conditions were "Capabilities required to reproduce BTS image" and "Motivation for contributing BTS image." The actions/interactions were "Presenting BTS image," "Contribution to the spread of BTS image," and "Involved in forming new BTS image." The result was "Emergence and expansion of new BTS image meaning" and "Strengthening attachment to BTS." Through process analysis, it was found that acceptance of BTS images consisted of five stages: "Recognition of BTS image," "Becoming curious about BTS image," "Searching BTS image," "Intervention of BTS image." and "Reproduction of BTS image." As a result of deriving the core categories through selective coding, the core category was "Forming a bond while participating in the BTS image."
