Objectives: The purpose of this scoping review is to suggest future treatment and research directions for adult ADHD by examining domestic trends in Korean research on adults with ADHD tendencies. Methods: The present review used Arksey and O'Malley's scoping review methodology. Eight domestic databases were used, and a search was conducted in July 2023 while targeting domestic papers that had been published within the last 20 years. Subject keywords included 'College student', 'Soldier', and 'Adult', and the subject-related terms that were searched for included 'ADHD'. Results: From 502 initially collected articles, 78 were ultimately selected for analysis in this work. Domestic research related to adult ADHD has been steadily conducted since 2000, and most such research has been done in psychology. Regarding the research participants, those in their 20s were the most common age group, and college students accounted for more than half of participants. In terms of study design, survey studies were the most common, while there was a lack of studies on intervention. The subject most closely dealt with in ADHD studies was interpersonal relationships, followed by depression and addiction. The main intervention used in this study was cognitive behavioral therapy, however it was limited in number. Conclusions: More multifaceted studies on adult ADHD need to be conducted using various research methodologies, and there is also a need for more studies using interventions. It is also important for such research to be expanded to broader geographic areas, ages, and occupations.

This review is aimed at the understanding of learning in field-trips relating to education in outdoor activities. The review specifically concerns what studies have been undertaken by seeking evidence from research published between 1950 and 2004. The review indicates three common arguments on learning during field-trips. First, the learning in an informal learning environment based on first-hand experiences is most significant when it has meaning for the learner from field-trips. Second, learning aims and strategies in field-trips have evolved along with world-wide concerns towards the environment. Third, the experiences from field-trips can impact significantly on students' cognitive and affective learning. However, the research of field-trip experiences from outdoor activities has focused on learning outcomes far more than on the learning characteristics which facilitate students' learning. Therefore, further study is required, which can provide clear evidence on how such learning characteristics through field-trips can help studentsto successfully attain educational goals.

Opinion mining involves the analysis of customer opinions using product reviews and provides meaningful information including the polarity of the opinions. In opinion mining, feature extraction is important since the customers do not normally express their product opinions holistically but separately according to its individual features. However, previous research on feature-based opinion mining has not had good results due to drawbacks, such as selecting a feature considering only syntactical grammar information or treating features with similar meanings as different. To solve these problems, this paper proposes an enhanced feature extraction and refinement method called FEROM that effectively extracts correct features from review data by exploiting both grammatical properties and semantic characteristics of feature words and refines the features by recognizing and merging similar ones. A series of experiments performed on actual online review data demonstrated that FEROM is highly effective at extracting and refining features for analyzing customer review data and eventually contributes to accurate and functional opinion mining.

Purpose: To develop the patient classification system based on the resource utilization for reimbursement of long-term care hospitals in Korea. Method: Health Insurance Review & Assessment Service (HIRA) conducted a survey in July 2006 that included 2,899 patients from 35 long-term care hospitals. To calculate resource utilization, we measured care time of direct care staff (physicians, nursing personnel, physical and occupational therapists, social workers). The survey of patient characteristics included ADL, cognitive and behavioral status, diseases and treatments. Major category criteria was developed by modified delphi method from 9 experts. Each category was divided into 2-3 groups by ADL using tree regression. Relative resource use was expressed as a case mix index (CMI) calculated as a proportion of mean resource use. Result: This patient classification system composed of 6 major categories (ultra high medical care, high medical care, medium medical care, behavioral problem, impaired cognition and reduced physical function) and 11 subgroups by ADL score. The differences of CMI between groups were statistically significant (p<.0001). Homogeneity of groups was examined by total coefficient of variation (CV) of CMI. The range of CV was 29.68-40.77%. Conclusions: This patient classification system is feasible for reimbursement of long-term care hospitals.

For years, research on the impact of students' attitudes on learning has maintained a spot amongst the most highly discussed topics in education. Particularly, over the past decades, researchers have made great strides in better understanding attitudes toward computers. This article presents a critical review of the current state of research by re-examining how attitudes toward computers have been studied. First, the review introduces an overview of the theoretical foundations and the origins of research on attitudes toward computers. Then, the article summarizes previous literature and knowledge about computer attitudes and provides a review of major findings from research on the effects of some factors affecting the formation of computer attitudes. The discussion reveals a number of major issues and challenges, which include unclear characterization of computer attitudes, problems with measurement tools, and the lack of studies using methods other than brief questionnaires. The unsolved problems cause conflicting, inconsistent and inconclusive results and affect interpretation in the study of computer attitudes. The article also suggests the main recent and future directions of research on attitudes toward computers. Finally, it concludes by providing implications for educators.

Purpose The impact of online reviews is widely acknowledged, with extensive research focused on text-based reviews. However, there's a lack of research regarding reviews in video format. To address this gap, this study aims to explore the connection between company-sponsored product review videos and the extent of directive speech within them. This article analyzed viewer sentiments expressed in video comments based on the level of directive speech used by the presenter. Design/methodology/approach This study involved analyzing speech acts in review videos based on sponsorship and examining consumer reactions through sentiment analysis of comments. We used Speech Act theory to perform the analysis. Findings YouTubers who receive company sponsorship for review videos tend to employ more directive speech. Furthermore, this increased use of directive speech is associated with a higher occurrence of negative consumer comments. This study's outcomes are valuable for the realm of user-generated content and natural language processing, offering practical insights for YouTube marketing strategies.

Objectives: This literature review was conducted to understand overall research trend and change in school health education during the past 20 years and to identify major outcomes and future directions of research. Methods: Descriptive literature review was conducted for school health education in Korea. A total of 117 peer-reviewed journal articles and thesis published between 1900 and 2008 (for 19 years) conducted in school were finally included in this review process. The research setting should be elementary, middle, or high schools and the major topic of the research should health education for students. Results: Research in elementary school was 38.0% which was greater than research in middle or high school setting. Surveyor intervention research was slightly increased in 2000s. General health and other review were the most frequently employed topics in 1990s' research and general health, smoking, and safety were in 2000's research, which implied that recently research specified its topics more than 1990s' research. Recently research was developed in intervention model comparing with 1990s' research. Research using experimental or quasi -experimental design seems having less intervention effects than the research using nonexperimental design. Conclusions: It is necessary that health education research in school focuses more in students' interest, participation, and factors related to intervention effects from now on.

Although service innovation is not a new concept, innovation research in general tends to focus on technological innovation by manufacturing firms. With this view, innovation studies focus on product(e.g., goods) and process(e.g., product systems) innovation, ignoring service innovation and its inherent opportunities. Since major economy has been transformed to service economy, service innovation is considered a new effective way to sustain and gain a competitive advantage. Service innovation is no longer regarded merely as a side activity to product innovation; it has become a main research topic in its own right, accompanied by an increasing focus on services. While the number of service innovation studies has increased dramatically in the past 30 years in international research, few studies have been performed in domestic studies because domestic service innovation research began from the middle of 2000. In addition, there are no comprehensive literature reviews describing the evolution of service innovation research in both international and domestic studies because of the heterogeneities of service industry and multidiscipline characteristics of service innovation studies. To bridge this research gap, the purpose of this paper is to perform an extensive literature review and synthesis to enable a critical review of extant research on service innovation and trace its evolution, which will establish a foundation for further studies. By reviewing 169 articles (136 international papers; 33 domestic papers) published between 2000 and 2014 (in past 15 years), primarily in leading service, innovation and management information systems journals, this study analyzes the progression of service innovation research according to the four aspects such as number of studies, topics, methodologies and target industries. Overall, the view of service innovation has evolved, from a complement of traditional product innovation to a multidimensional, all-encompassing concept that entails several functions, both within and outside the firms. The results showed that domestic research still stays at the formation phase of service innovation studies although international research is in the maturity or multidimensional phase. We found increasing recent activities pertaining to service innovation, resulting from the increasing interest in services innovation across various industries and the links of new topics to the service innovation concept in both international and domestic studies. However, the main focus of service innovation research showed a different propensity between international and domestic studies: the former mainly focuses on a much more diversified pattern, emphasizing the linkages between service innovation and business strategy while the latter mainly focuses on the service innovation process(system) and service design. In addition, there are many case studies in domestic studies while many empirical studies in international studies. Domestic studies should increases the understanding of the interplay between service innovation and product innovation within manufacturing firms. Furthermore, rather than focusing on intrinsic distinctions between service innovation and product innovation, researchers should strive to develop and conceptualize service innovation in domestics studies. The present research also provides useful implications for practitioners. First, this study contributes to expand the current understanding of service innovation research by performing an extensive literature review. Second, tracing and comparing the progression and trends of service innovation research between international and domestic studies, this study showed the similarities and differences between them, which provide practical guidance on future research directions and research agenda. Third, this study performed literature review establishing the analysis system in the initial stage and using them to analyze articles, which is leading to explain the research review of service innovation more systematically and objectively. Finally, this study suggests the domestic researchers their future interests and topics of service innovation research.
