A gene (xynA) encoding the endo-xylanase (E.C.3.2.1.8) from Bacillus stearothermophilus was cloned in E. coli, and its complete nucleotide sequence was determined. The xynA gene consists of a 636 base pairs open reading frame coding for a protein of 212 amino acids with a deduced molecular weight of 23, 283 Da. A putative signal sequence of 27 amino acid residues shows the features comparable with the Bacillus signal sequences; namely, the signal contains a positively charged region close to the N-terminus followed by a long hydrophobic string. The coding sequence is preceded by a possible ribosome binding site with a free energy value of -16.6 kcal/mol and the transcription initiation signals are located further upstream. The translation termination codon (TAA) at the 3 end of the coding sequence is followed by two palindrome sequences, one of which is thought to act as a terminator. The xynA gene has a high GC content, especially in the wobble position of codons (64%). Comparison of the primary protein sequence with those of other xylanases shows a high homology to the xylanases belonging to family G.

Purpose The purpose of this study is to investigate the nature of temporal non-use, namely, the type of temporal non-use and the dynamic relationships between temporary non-use and use by expanding the model of dynamic state transition of non-use which is proposed by the previous study. Design/methodology/approach This study adopted grounded theory methodology as a research methodology. Fifteen university students were interviewed for open coding and for selected coding which leads the research model ten students were interviewed. Findings Based on the coding, the types of use were divided into interactive use and one-way use, and the types of temporal use were classified into temporal non-use in which use is intended and temporal non-use in which use is not intended. The dynamic transition model is presented for each type of use and temporalnon-use, and an integrated model that combines them is presented. This study found the following four things: First, all non-use can be temporal Second, there are different types of temporal non-use. Third, the pattern of use is not just one, but new patterns will continue to emerge. Fourth, we found a change in the function of SNS.

This study conducted a qualitative study on 23 seniors over 55 years old to understand the digital behavior of seniors in the online education acceptance environment. Grounded Theory methodology was applied to the initial enrollment behavior, login behavior, and utilization behavior of online education program. Through the process of open coding, axis coding, and selective coding, the framework in the online education environment of the senior generation was finally derived. As a causal conditions for the senior generation to participate in the online education environment, goal orientation, relationship orientation, leisure orientation and external compulsory were derived, and shadow work appeared as the central phenomenon. Also, contextual conditions resulted in social change, physical and cognitive aging, and psychological atrophy. The intervening conditions included digital device acceptance, educational attitudes, environmental factors, and self-efficacy. Based on this, the action/interactions strategy formed a positive and negative attitude toward shadow work. As a result, positive response behavior, compromising behavior, and shadow work avoidance behavior were shown. It is hoped that this study will be reflected in future researches for the use of digital devices of the elderly and the expansion of online education participation and government policy.

The purpose of this study was to figure out the procedure of learning Korean for international students. A research question was set up as follows: What is the procedure of leaning Korean for international students in Korean universities? To achieve the research purpose, this study implemented a method of semi-constructed interviews. Nineteen international students participated in the interview. The collected data for this study included transcripts from each interview. The transcripts of 60 minutes of interviews with all the participants was audio-taped recorded. This study investigated the research question based on the grounded theory. The analysis of open coding, axial-coding, and selective coding was used in the study. Results indicated that international students learned Korean in a daily basis, and then they adapted to academic Korean in their majored fields. Both personality and mother tongue influenced Korean language learning positively and negatively. International students' improvement of Korean was related in studying with Korean mass media such as TV soap dramas, talk shows, and songs. International students think that TOPIK(Test Of Proficiency In Korean) is not much related with their Korean language fluency. In conclusion, the researchers suggested to give more emphasis on academic training courses for Korean language and to improve the TOPIK in general academic Korean.

In this study, we tried to understand preschooler clothing trends and identify the purchase behaviors of various consumers, such as grandparents, aunts, uncles, and parents, who are the main consumers of the preschooler clothing market. We conducted in-depth interviews with consumers who were interested in preschooler clothing, purchased it frequently, and bought preschooler clothing within the last three months. Their purchase motivations and purchase behaviors were analyzed through exploratory and inductive analysis. The analysis was conducted by integrating categories into one process centered on core categories through open coding, axial coding, and selective coding. The results of this study included that 1) a variety of clothing purchase behaviors appeared as a central phenomenon, 2) the causal conditions that contributed to this phenomenon were the buyers' childcare experiences, purchase experiences, the personal consumption values of individuals, and income levels, 3) in response to the central phenomenon, the parents' action/interaction strategies were acceptance and rejection of purchased clothing, 4) contextual and Intervening conditions affecting action/interaction strategy were family environment changes, the VIB (Very Important Baby) phenomenon, parents' clothing involvement, and the relationship with the buyers, and acceptance by the users, and 5) as a result of the strategy expressed as acceptance and rejection, various clothing behaviors emerged. In this study, we identified that there are various influencers, apart from parents, involved in children's clothing consumption. Therefore, we need to keep in mind that various purchase behaviors and clothing trends that appear during one's childhood may affect the individual's clothing behavior in the future.

This study presents a conceptual framework for the growth process as a manager based on data gathered from the sales experiences and careers of fashion brand managers. The study participants were seven managers with over 15 years of sales experience in a women's clothing brand in Gwangju. Data were collected through in-depth interviews from January 2018 to September 2018 and analyzed using open coding, axis coding, and selective coding according to Strauss and Corbin's grounded theory method. The study results are as follows. First, this study found six categories and 17 sub-categories based on the shop manager's sales experiences and careers. Second, we found the central job category as well as categories with causality, interaction, moderating and outcome relationships. Third, we developed a paradigm model that links the main phenomena, causal conditions, contextual conditions, intervening conditions, action/interaction strategies, and consequence categories. Fourth, the process of growing as a fashion brand manager was described by an integrated story.

Purpose This study is to phenomenologically discover key antecedents and outcomes of behavioral process of SNS users who have multiple SNS sub-accounts. Unlike previous studies that focused on user behavior in the context of a specific SNS platform, this study attempts to describe how and why individual manages their multiple sub-accounts across a variety of SNS platforms. Design/methodology/approach By applying the grounded theory methodology (GTM) to elucidate the unique behavior in SNS platforms, this study has conducted in-depth interview with 14 respondents who handle multiple accounts across the SNS platforms. As a results of analyzing the interview manuscripts, this study has extracted 47 concepts, 10 sub-categories and 6 main categories by conducting open coding, axis coding, and selective coding. Findings By analyzing interview data, this study has derived main categories such as account management, impression management, self-categorization, authority to determine the relationship, digital shadow work, and portfolio SNS accounts from qualitative interview data. This study has also conducted a process analysis that represents how main categories could be inter-related. Based on findings, this study provides a new phenomenological perspective to understand the behavioral process of SNS users' sub-account usage experience.

Purpose The purpose of this study is to analize a psychological and behavioral mechanism for using profile picture management in digital service such as social network service. Profile picture management falls under metadata management and is performed only by those who want it. This means that it, is one of the typical makeup-type digital shadow works (DSWs) which have not been studied yet. Design/methodology/approach This study adopts ground theory method(GTM) as research methodology. GTM, which is one of qualitative methodologies, is for developing theories while most survey based methodologies, which are well adopted in much research for information systems, are for validation of theories. By interviewing ten users, the data are collected and analyzed by open coding, axis coding with paradigm model, and selective coding. Findings In result, 39 codes are found and classified into 29 sub classes and 15 classes. These 15 classes are organized by paradigm model which derives core code of profile picture management as 'voluntary management tasks to experience small pleasures with intermittent attention'. Finally, based on the paradigm model and the core code, the story line, which can explain profile picture management, is suggested.

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."

Purpose The purpose of this study is to identify the role of digital shadow work(DSW) in the psychological mechanism that controls using and purchasing digital device accessories. More specifically, it is to reveal how the digital device user's perception of DSW is formed and how the formed DSW affects purchase and what results it will bring. Design/methodology/approach Ground theory method(GTM), one of qualitative appoaches, is adopted as research methodology. By interviewing total twenty five users, the data are analyzed by open coding amd axis coding. Two core codes are selected by selective coding and interpreted by DSW theory. Findings We find concern for potential DSW and generation of new DSW. Concern for potential DSW lead to the purchase of accessorie which would be supposed to reduce potential DSW. During purchasing accessories, quest type DSW, which provices flow experience and expertise, could be genterated. This means that there would be dynamics of DSW in the purchase process of digital device accessories.
