Hotel consumers tend to rely on online reviews to reduce the risk to hotel products when they book hotel rooms because hotel products are high-risk products due to their intangibility. However, the development of ICT has caused information load, and it is an important issue to be perceived as useful information to consumer because a large amount of information complicates the decision making process of consumers. Drawn from Heuristic-Systematic Model(HSM), the present study explored the role of heuristic and systematic cues composing an online review influencing consumers' perception of hotel online reviews. More specifically, this study identified reviewers' identity, level of the reviewer, review star ratings, and attached hotel photo as heuristic cue, while review length, cognitive level of review and negativity in review as systematic cues. The binary logistic regression was adopted for analysis. This study found that only systematic cues of online review were found to affect the usefulness of it. Moreover, we preceded further study examining the moderating effect of seasonality in the relationships between systematic cues and usefulness.

BACKGROUND/OBJECTIVES: The Dietary Reference Intakes for Koreans (KDRIs), a set of reference intake values, have served as a basis for guiding a balanced diet that promotes health and prevents disease in the general Korean population. In the process of developing DRIs, a systematic review has played an important role in helping the DRI committees make evidence-based and transparent decisions for updating the next DRIs. Thus, the 2015 KDRI steering committee applied the systematic review framework to the revision process of the KDRIs. The purpose of this article is to summarize the revision process for the 2015 KDRIs by focusing on the systematic review framework. MATERIALS/METHODS: The methods used to develop the systematic review framework for 2015 KDRIs followed the Agency for Healthcare Research and Quality and the Tufts Evidence-based Practice Center. The framework for systematic review of the 2015 KDRIs comprised of the 3 following steps: (1) development of an analytic framework and refinement of key questions and search terms; (2) literature search and data extraction; and, (3) appraisal of the literature and summarizing the results. RESULTS: A total of 203,237 studies were retrieved through the above procedure, with 2,324 of these studies included in the analysis. General information, main results, comments of reviewers, and results of quality assessment were extracted and organized by study design. The average points of quality appraisals were 3.0 (range, 0-5) points for intervention, 6.1 (0-9) points for cohort, 6.0 (3-9) points for nested case-control, 5.4 (1-8) points for case-control, 14.6 (0-22) points for cross-sectional studies, and 7.0 (0-11) points for reviews. CONCLUSIONS: Systematic review helped to establish the 2015 KDRIs as a useful tool for evidence-based approach. Collaborative efforts to improve the framework for systematic review should be continued for future KDRIs.

Purpose: The aims of this study were to identify the psychosocial interventions for patients with alcohol use disorder and to assess the effects of those interventions. Methods: A systematic literature search was conducted using PubMed, the Cochrane Library, Embase, CINAHL, PsycINFO, KoreaMed, KMBASE, RISS, KISS, Science ON, and DBpia to identify studies reported in English or Korean from 2012 to 2021. Results: From the 4,051 studies extracted, 14 studies were selected for review. The majority of the psychosocial interventions were focused on cognitive therapy or cognitive-behavior therapy. Most of the studies reported that the interventions made positive effects on alcohol consumptions. In addition, the psychosocial interventions for patients with alcohol use disorder were effective on coping, support, alcohol avoidance behavior, and hostility bias. Most of the studies reporting positive effects of psychosocial intervention programs applied computers, mobile phones, or similar electronic devices. Conclusion: The findings of this systematic review suggest that the use of computers or mobile devices in psychosocial intervention programs will be effective. It can be said that this systematic review reflects the current trends involving the development of information and communication technology. This systematic review can provide basic data for establishing evidence and suggesting future directions for psychosocial interventions for patients with alcohol use disorder.

Objective: The purpose of this study was to systematically review the trunk impairment scale that are used to assess the trunk control of stroke patients. Design: A systematic review Methods: Stroke subjects were categorized as acute, subacute, chronic. In this systematic review, the studies published between 2000 and 2020 were selected. A literature search using the keywords 'QUADAS', 'stroke', 'trunk impairment scale'. Data sources included RISS, GOOGLE Scholar and DBpia. We assessed the quality of assessment tools using Quality Assessment of Diagnostic Accuracy Studies tool. Results: We reviewed 18 studies. 7 of the 18 studies reported reliability results, 10 reported validity results. The QUADAS tool quality evaluation of 17 literatures extracted except for one randomized control test among 18 literatures showed a range of 3 to 13 points. 5 of the 18 studies are presented with the Cronbach alpha coefficient indicating reliability using internal consistency, all of which are more than 0.8. All studies that presented test-retest reliability, intra-rater reliability, and inter-rater reliability showed high agreement with an intra-class correlation coefficient of 0.75 or more. Conclusions: A systematic review of the study of the application of the trunk impairment scale for stroke patients will help provide criteria for future studies and application of the trunk impairment scale in clinical practice.

Purpose: The aim of this study was to analyze the cause of alcoholism based on a systematic review of previous studies published from 2009 to 2014. Methods: The study design was a systematic review of the literature in which factors constituting causes of alcoholism were analyzed. Search words used to retrieve foreign studies were "alcoholism" or a combination of "alcohol dependency" and "etiology" or "predictor. Research Information Sharing Service (RISS) of the Korea Education and Research Information Service and Dbpia, a database for domestic academic studies, were used as search engines for retrieving domestic papers. Results: The systematic literature review found that for emotional and psychological factors as etiology of alcoholism, abuse-related factors had the largest proportion with a total of 63%. Conclusions: In this study factors related to alcoholism were examined in terms of emotions, psychology, environments, families and others. As a result, it was found that alcohol consumption at an early age and experience of abuse were major causes for alcoholism.

The earlier literature widely documented the role of natural resources in economic development and confined their findings either in support of resource blessing growth or resource curse hypothesis. The ample research on the stated theme has available in the relevant databases, supported with empirical data, while a few studies used a case study or mixed-method approach. The study identified plenty of room on a given topic by conducting a systematic literature review and synthesizing the literature in more meaningful inferences. After a thorough investigation of the literature review through systematic intervention, the study concludes that natural resource management is imperative for a country's sustained growth. Simultaneously, it is desirable to reduce resource conflicts, improve institutional performance, decrease corruption, and stabilize the political environment to get maximum natural resource management potential globally.

Purpose: This study aimed to review recent findings from birth cohort studies on maternal and child environmental health. Methods: Birth cohort studies regarding environmental health outcomes for mothers and their children were investigated through a systematic review. A literature search was conducted in PubMed, CINAHL, the Cochrane Library, Embase, and RISS to identify published studies using the keywords using a combination of the following keywords: maternal exposure, environmental exposure, health, cohort, and birth cohort. Articles were searched and a quality appraisal using the Newcastle-Ottawa Scale for cohort studies was done. Results: A review of the 14 selected studies revealed that prenatal and early life exposure to environmental pollutants had negative impacts on physical, cognitive, and behavioral development among mothers and children up to 12 years later. Environmental pollutants included endocrine disruptors, air pollution (e.g., particulate matter), and heavy metals. Conclusion: This systematic review demonstrated that exposure to environmental pollutants negatively influences maternal and children's environmental health outcomes from pregnancy to the early years of life. Therefore, maternal health care professionals should take steps to reduce mothers' and children's exposure to environmental pollutants.
