Purpose: This study was conducted to review physiological mechanisms of internet addiction and to construct a theoretical framework for cognitive behavioral therapy for internet addicts. Methods: We searched for relevant literature in the PubMed and RISS databases using the terms "internet addiction", "internet game addiction", "internet abuser", and "online game". Only English, full-text articles published from 2000 to 2015 were included in this review of physiological indicators of internet addiction. Finally, 12 articles were selected for review. Results: The theoretical framework developed based on the review proposes that excessive internet use itself may induce physiological stress responses with an increase of stress-related hormones and neurotransmitters. Prolonged abnormal responses of these physiological features produce negative structural and functional changes in the prefrontal cortex, which is mainly involved in cognitive and executive functions. These changes may result in decreased cognitive function. As a stressor, excessive internet use leads to transforming voluntary use into involuntary, habitual use and thus promotes the development of internet addiction. Conclusion: The proposed theoretical framework encompasses cognitive processes that may contribute to the effects of internet use-induced physiological stress on internet addiction. We believe that this framework has important implications for developing cognitive behavioral strategies for internet addicts.

Environmental quality(EQ) is one of the most important components of the assessment of "Quality of Life(QOL)". Most EQ related research dealt with overall built environmental quality issues as represented by several clusters of factors related to occupants' satisfaction. This paper aims to identify and understand the theoretical background and the occupants' comparative standards of response to conditions of the built environment related to environmental quality(EQ). Therefore, this paper have reviewed the theoretical framework and empirical research for environmental quality in built environment. the concept of environmental quality if elaborated from diverse perspectives. Different ways of interpreting environmental quality have led to a variety of ways to conduct evaluations. A review of the theories and methods used for the analysis of perceived environmental quality provides a strong foundation for new research frameworks and environmental quality in built environment.

This study aims to review the research trends concerning environmental psychology. The scope of review is limited to the papers that dealt with theoretical and case-directed investigation research about the relationship between socio-physical environments and human beings. The relationship has been investigated by diverse human reactions such as cognitive, emotional, analytical, behavioral, and comprehensive. 219 papers were reviewed in two steps. In the first step, the ratio of the papers in the field of environmental psychology to the total papers published in the Journal from 1973 to 2004 was analyzed. Second, all the 219 papers were classified by such three criteria as the type of the paper(theoretical, review, case investigation), the methodology taken, and the main theme of the paper. The main findings from the review are summarized as follows; 1. Out of the 219 papers, the number of the theoretical papers was 4 (1.8%), whereas the number of the case investigation papers was 185 (84.5%). 2. Out of the 30 review papers, the main methodology used was simple introduction (15 papers, 50%) and the main theme was research methodology (36%), whereas analytic comparison was used only in 10 papers (33%) and theory review was only found in 6 papers (20%). 3. Out of the 185 case investigation papers, experimental method was found in 34 papers (18%), whereas 99 papers used correlational method (54%). Based on the findings, it was suggested that both theoretical and case-directed research should be performed in order to enhance the state of art in environmental psychology. Theoretical research as a framework to understand the empirical findings are as important as the case-investigation research peformed by scientific experimental method.

Purpose: The underdog effect refers to a positive attitude towards the underdog who lacks resources and opportunities but has passion and determination. Extensive research has been investigated how the underdog effect affects distributing consumer preference and purchase intention. The purpose of this study is to identify the theoretical basis on which the underdog effect is grounded by analysing the prior research in the underdog literature. Research design, data and methodology: This study organizes the literature on the underdog effect by analyzing a total of 33 journals published in the past 16 years. Constructs and variables were extracted from the selected articles through the content analysis on a systematic literature review. Results: This literature review reveals that identity theories served as an overarching theoretical lens when examining the underdog effect. Additionally, the underdog effect was rooted in theories of justice and equity to explain the relationship between underdog brand positioning and consumer preference. Conclusions: This paper paves the way for future research based on prior research and trend analysis of underdog brand positioning. This article also provides an insightful interpretation and synthesis of the theoretical underpinnings of the impact of underdog effects on consumers' overall brand evaluations.

Can we use the open innovation paradigm in Korean economy? Can Korea move from imitative national innovation system to Creative national innovation system without open innovation paradigm? We are looking for preliminary answers about these questions. In this paper, first of all, we review the theoretical factors of open innovation originated from professor Chesbrough, try to find out the limit of the theory, and propose the possibility of extending of open innovation from company to industrial sector, region and cluster, and national innovation system. We also review the user innovation models from Von Hippel and open business models. Second, we review the Korea open innovation cases according to the categories like as company, sector, cluster and regional innovation system, and national innovation system. Third, we prepose the theoretical and realistic implications, and next research agenda about Korea open innovation.

Purpose: This study reviewed the pathophysiological mechanisms of cellular aging caused by psychological stress and aimed to establish a biobehavioral theoretical framework for nursing interventions to promote autonomic balance based on these mechanisms. Methods: A comprehensive literature review was conducted. Results: A review of the literature showed that the stress response increases the secretion of catecholamines and glucocorticoids, resulting in a greater allostatic load. This load induces inflammatory reactions and oxidative stress, shortening telomere length and damaging mitochondrial DNA, which can lead to cellular aging. Based on this mechanism, a biobehavioral theoretical framework for nursing interventions was established. This framework focuses on delaying or inhibiting the cellular aging process by acting on the stress response stage and improving autonomic balance. Conclusion: According to the proposed biobehavioral theoretical framework, stress-relieving nursing interventions may act on the mechanism of cellular aging caused by stress responses. We believe that this framework could expand our understanding of the biobehavioral aspects of stress and would facilitate efforts to use biomarkers to evaluate the effectiveness of stress-related nursing interventions at the cellular level.

This literature review was undertaken to explore theoretical models of depression for their potential usefulness in nursing research and practice. Depression has bean accounted for by numerous theories or models of causation ; 11 theories selected from psychology, medicine and psychoanalysis and supported by empirical or experimental research were reviewed. These theories identify a variety of precipitating and predisposing factors that may affect the individual's depression. Aggression - turned - inward theory, object loss theory, ego functioning theory, personality organization theory, behavioral theory, learned helplessness theory, cognitive theory, genetic factors, and biological theories conceptualize predisposing factors. Only life stressors theory identifies precipitating facotrs. Each of these theories contributes to an understanding of depression, but many of them use overlapping and interrelated factors. It is also evident from recent. research that there are multiple causes for depression involving an interactive effect among predisposing and precipitating factors that are both biological and psychological in origin. That is, a single theory is not useful, but perhaps a unified theory could be developed that would be helpful to nursing. This review points to the need for continuing development and testing of theories that would integrate the multiple conceptualizations of depression.
