Previous studies have found that the use or development of theory in library and information science (LIS) research is comparatively low and may be trending downward. LIS has also been criticized for relying on theories imported from other disciplines rather than applying or developing theories from within. The theory of information worlds, a social information behavior theory originally introduced in 2008, represents a newer LIS theory whose level of adoption is understudied. This study features a systematic literature review of peer-reviewed research articles which cited or used the theory of information worlds from 2008 to early 2022 to identify trends related to levels of theory use, publication venues, author affiliations, countries, and collaborations, as well as research methods, topics, and populations. Findings suggest that both awareness and use of the theory of information worlds are positively trending, though at slower rates for higher levels of theory use, such as full applications of the theory to guide the collection and analysis of empirical data. The theory has also been used by researchers from around the world and across disciplines, most often with mixed and qualitative methods. While the growth of a new LIS theory is promising, the authors echo calls for increased use and development of the theory of information worlds, and other LIS theories more broadly, and as more interdisciplinary collaboration.

This paper focuses on a sociologic approach, the theory of planned behavior (Ajzen 1991) and a sociolinguistic field, the language shift (Fishman 1991, Crystal 2000). It describes the theoretical background of language shift and briefly mentions the history of Hungarian language and Romanian language contacts. After presenting language use of the Hungarian minority students and explaining the theory of planned behavior, it turns to apply the theory of planned behavior to the language shift from the view of bilingual speaker(s). This paper wants to propose the application of the theory of planned behavior in language shift and open new perspective in bilingual research.

A conceptual framework, based on a curriculum model of family life education content, and on a schema for analyzing explicit use of theory, was developed to discern the substantive themes of programs and the role of theories in publications on programs for families in the Korean family studies literature. Seventy two journal articles published between 1990 and 2002 were analyzed. The results revealed that the Korean family life education programs dealt with the breadth of topics, but most particularly internal family dynamics and interpersonal relationships, and utilized theoretical concepts as input and output in a different level: explicit, implicit, or no use of theories. Implications for future research and practice in Korean family life education are discussed, including gaps in the substantive foci of programs, and aligning programs more closely with theory.

In this paper, we applied Sfard's reification theory to analyze the secondary students' level of conceptualization with regard to the formula of quadratic equation. Through the generation and development of mathematical concepts from a historical perspective, Sfard classified the formulation process into three stages of interiorization, condensation, and reification, and proposed levels of formulation. Based on this theory, we constructed a test tool reflecting the reversibility of the nature of manipulation of Piaget's theory as a criterion of content judgement in order to grasp students' conceptualization level of the formula of quadratic equation. By applying this tool, we analyzed the conceptualization level of the formula of quadratic equation of the $9^{th}$ and $10^{th}$ graders. The main results are as follows. First, approximately 45% of $9^{th}$ graders can not memorize the formula of quadratic equation, or even if they memorize, they do not have the ability of accurate calculation to apply for it. Second, high school curriculum requires for students to use the formula of the quadratic equation, but about 60% of $10^{th}$ graders have not reached at the level of reification that they can use the formula of quadratic equation. Third, as a result of imaginarily correcting the error of the previous concept, there was a change in the levels of $9^{th}$ graders, and there was no change in $10^{th}$ graders.

There are a number of studies about the impact of social games' social network. But because of conflicting results, the game's effect isn't ascertained. In this study, we defined that using social games makes increase the social capital with construal level theory. The survey results on construal level, social capital, game using time, etc, are used for the analysis of the correlation and interact. As a result, growing bridging social capital shows on the people who use high level of construal and more social game time use. This phenomenon did not appear in other online games, so that makes a social games' feature unique characteristic. And we discovered that high level construals is key point for defining the practical use of media.

Construal level theory (CLT) have been researched in wide range of disciplines such as marketing, organizational study, psychology, or education. Current study asserts that CLT would explain the effect of different devices of PC and smartphone on interaction between human-computer interfaces and information systems use. In CLT, those who are far from an object in terms of physical, temporal, social or psychological distance, they construe their understanding as abstract (high level) and vice versa. We hypothesized different size of digital device will increase psychological distance and result in behaviors that correspond to present construal level. The analysis result shows that users of PC recognized that they are socially distant from the device and those of smartphone felt that they are socially close to the device. However, the device did not have significant effect on attention to essential information, advertisement preference, and immediacy. The implication to academia, practice and future research and limitations are also discussed.

Based on a previous literature about hospital capital structure(Shyam- Sunder & Myers, 1999), this study attempted comparison and analysis on whether the forecast of trade-off and pecking order theory could be validated in hospital's capital structure. First, this study analyzed whether hospitals follow the priority for each capital source as suggested by pecking order theory under lack of capital running in hospital. Next, it analyzed whether debt level is regressed on the average to target debt level so as to verify the validity of trade-off theory. Finally, it also analyzed possible associations between debt level and determinants of capital structure as adopted in static trade-off theory, so as to verify relative advantages of these two theories about hospital capital structure. The analysis over whole period showed that both trade-off theory and pecking order theory isn't supported particularly. This mean that each hospital's financing behaviors is different and that has not dominant financing behaviors. In the midst of separation of dispensary from medical practice, medical institutions in Korea first finances funds required using retained earnings and then use liabilities. however pecking order theory is supported, the preference of long-term liabilities and short-term liabilities is not clear. In addition, considering that debt level is in no average regression to target debt ratio, it is found that hospital capital structure following trade-off theory turns into that subject to pecking order theory via the separation of dispensary from medical practice.

This study was conducted to explain airport users' acceptance intention for untact smart devices being introduced at Incheon Airport. Based on the technology acceptance model, perceived usefulness and ease of use influenced attitudes and intention to use. It was verified whether it was affecting the effect. In addition, variables proposed in innovation diffusion theory were selected to verify exogenous variables that affect perceived usefulness and ease of use, which serve as key independent variables in the technology acceptance model. Research results show that perceived usefulness has a high level of positive influence on attitude, whereas perceived ease of use has a low influence and does not show a statistically significant influence. In addition, it was confirmed that most variables of the innovation diffusion theory had no effect on usefulness and ease of use. This means that the key variable in the spread and use of untact smart devices at airports is the perception of usefulness, which means that resistance to accepting new technology is not high.

Purpose: This study was done to examine the level of use of essential oriental nursing terms and related characteristics among nurses in oriental medicine (OM) hospitals. Method: A cross-sectional survey design with convenience sampling was employed. Questionnaires were used to collect data from 315 nurses in seven university-affiliated OM hospitals. The questionnaire included 174 oriental nursing terms about actions, tests, drugs, and theories. Multiple regression analysis was performed to determine factors associated with the level of use. Results: The response rate was 98.1% (n=309). Overall mean score for use of essential oriental nursing terms was 2.7(${\pm}\;0.7$) on a five-point Likert scale. Significant factors associated with the level of use were workplace and knowledge of oriental nursing theory terms. Nurses who worked in nursing care wards and those who had a higher level of knowledge of oriental nursing theories had a higher level of use. Conclusions: These findings indicate that level of use of essential oriental nursing terms were below average. Educational programs to enhance knowledge of oriental nursing theories need to be implemented for nurses in OM hospitals, considering their workplace, in order to facilitate nursing data sharing and communication among healthcare providers.

This study identifies and tracks changes gender differences in adolescent users' problematic online behavior. This study used Korea Youth Panel Survey (KYPS), which has tracked respondents over 7 years, with self-control theory and social learning theory applied as a theoretical framework. The model included individual-level variables such as self-control and respondent's experience of problematic behavior (offline), as well as socialization variables such as the number close friends who engaged in problematic offline behavior, parent-child relationships, and parental monitoring. Dependent variables included problematic online behavior, unauthorized ID use (ID theft) and cyberbullying (cursing/insulting someone in a chat room or on a bulletin board). Control variables consisted of academic performance, time spent on a computer, monthly household income, and father's educational attainment. Random and fixed effects models were performed by gender. Results supported self-control theory even for the within-level analysis (fixed effects models) regardless of gender, while social learning theory was partially supported. Only peer effects were found significant (except for unauthorized ID use) among girls. Year dummy variables showed significant negative associations; however, academic performance and time spent using computers were significant in some models. Father's educational attainment and monthly household income were found insignificant, even in the random effects models. We also discuss implications and suggestions for future research and policy makers.
