  • The main purposes of this study were (a) to analyze the research trend of educational use of tangible technology, (b) to identify tangible learning mechanisms, and potential benefits of learning with tangible technology, and (c) to provide references and future research directions. We conducted a systematic literature review to search for academic papers published in recent five years (from 2013 to 2017) in the major databases. Forty papers were coded and analyzed by the established coding framework in four dimensions: (a) basic publication information, (b) learning context, (c) learning mechanism, and (d) learning benefits. Overall, the results show that tangible technology has been used more for young learners in the kindergarten and primary school contexts mainly for science learning, to achieve both cognitive and affective learning outcomes, by coupling tangible objects with tabletops and desktop computers. From the synthesis of the review findings, this study suggests that the affordances of tangible technology useful for learning include embodied interaction, physical manipulations, and the physical-digital representational mapping. With such technical affordances, tangible technologies have the great potential in three particular areas in education: (a) learning spatial relationships, (b) making the invisible visible, and (c) reinforcing abstract concepts through the correspondence of representations. In conclusion, we suggest some areas for future research endeavors.

  • Sustainability is considered to be one of the most important social and environmental requirements of modern companies located in global supply chains, since the strong worldwide regulation on carbon emission due to global warming has been emphasized. Sustainable Supply Chain Management(SSCM) could be one of the great alternatives for global companies to maintain a pleasant business environment while fulfilling their social and environmental responsibilities. This paper aims to provide research trends and future directions on SSCM through a systematic literature review. From January of 2004 to May of 2021, 185 English-written and peer-reviewed articles published in eminent journals were selected for the review. The all reviewed papers have been published in SSCI, SCI and SCIE indexed journals and should have accredited by WOS and JCR. A descriptive analysis was followed by a content analysis with regard to research design and methods, and data analysis techniques. We found that the number of research in the field of SSCM have been recently increasing and researchers and their affiliation have been expanding to all over the world, especially to emerging countries. We also found that the rate of the empirical studies and relevant research methodologies applied to the selected papers were relatively high. In the future, it is desirable to be increased the number of the specific industry-oriented research and the quantitative research pursuing the optimality.

  • Margin inclusion or exclusion remains the most critical and controversial aspect of stereotactic radiosurgery (SRS) for metastatic brain tumors. This review aimed to examine the available literature on the impact of margins in SRS of brain metastasis and to assess the response of some medical physicists on the use of these margins. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was used to review articles published in PubMed, Embase, and Science Direct databases from January 2012 to December 2022 using the following keywords: planning target volume, brain metastasis, margin, and stereotactic radiosurgery. A simple survey consisting of five questions was completed by ten medical physicists with experience in SRS treatment planning. The results were analyzed using IBM SPSS Statistics version 26.0. Of the 1,445 articles identified, only 38 articles were chosen. Of these, eight papers were deemed relevant to the focus of this review. These papers showed an increase in the risk of radionecrosis, whereas differences in local control were variable as the margin increased. In the survey, the response rate to whether or not to use margins in SRS, a critical question, was 50%. Margin addition increases the risk of radio necrosis. The local control rate varies among treatment modalities and cannot be generalized. From the survey, no consensus was reached regarding the use of these margins. This calls for further deliberations among professionals directly involved in SRS.

  • Anxiety disorder is a prevalent psychiatric issue that affects 4.05% of the global population. As complementary and alternative medicine gains popularity, many individuals with anxiety symptoms seek herbal remedies. This systematic review aims to explore the sedative efficacy of chamomile as an herbal medicine for anxiety treatment. Our search was conducted in PubMed, Google Scholar, and Scopus databases until August 2023. Among 389 papers found, after removing duplicates and irrelevant papers, 10 clinical trials investigating the effect of oral consumption of chamomile on anxiety were included. Two researchers independently completed all steps, including the screening process and data extraction. Out of the 10 articles selected, 9 studies have concluded that chamomile is effective in reducing anxiety. Even though, the exact mechanism of chamomile's anxiolytic action is not well understood, evidence suggests that its active compounds, including apigenin, may modulate the function of the hypothalamic-pituitary-adrenocortical axis by affecting neurotransmitter pathways. This systematic review showed that chamomile potentially has an anxiolytic effect. In addition, due to the side effects of drugs used to treat anxiety disorders, the use of chamomile seems to be effective and less dangerous.

  • Objectives : The purpose of this study is to analyze the treatment mechanism of Thread-embedding acupuncture, which is used in Korean medicine beauty treatment. Methods : After searching papers published up to January 1, 2023 using the keyword "Thread-embedding" through the OASIS site, we selected beauty papers that mentioned the treatment mechanism of Thread-embedding acupuncture. Results : A total of 60 papers were retrieved: 19 papers on the topic of cosmetic diseases, 35 papers on the theme of other diseases, and 6 papers written unrelated to diseases. Among the 19 papers on the topic of cosmetic diseases, one unreadable paper was excluded. Among the 18 papers, we finally selected 6 papers that mentioned treatment mechanisms: 2 on facial wrinkles, 2 on obesity, 1 on breast enlargement, and 1 on transdermal hydration. The treatment mechanism of Thread-embedding acupuncture is that in the case of facial wrinkles, polydioxanone(PDO) is embedded to fill the volume, and as it decomposes, it causes a tissue reaction around the area. In obesity, it promotes fat decomposition by improving circulation, and promotes breast enlargement and elasticity through collagen formation. In transdermal hydration, it induces the production of surrounding fibers to increase skin elasticity and moisture. Conclusions : Thread-embedding acupuncture appears to have a cosmetic effect through a mechanism that promotes the production of collagen and elastic fibers in the subepidermal dermal layer and increases the activity of skin moisturizing factors during the absorption process after the PDO suture is embedded.

  • Xerostomia is usually caused by a reduced salivary flow or by changes in the biochemical composition of saliva. Halitosis or oral malodor is an offensive odor usually originating from the oral cavity. Halitosis can lead to anxiety and psychosocial embarrassment. The occurrence of halitosis closely related with intraoral conditions including the presence of xerostomia. Especially, the relationship between xerostomia and halitosis is prominent in elderly patients receiving polypharmacy with at least two systemic diseases. This study is a review of the update literature of xerostomia and halitosis. A large number of papers have been searched and identified using the words , , , , , , and . Papers not relevant to the issue were removed reducing the entries to 79 only. Most of identified papers were systematic reviews, non-systematic reviews, and observational studies. With a proper diagnosis, identification of the etiology and timely referrals certain steps are taken to create a successful individualized therapeutic approach. It is significant to highlight the necessity of an interdisciplinary method for the treatment of xerostomia and halitosis to prevent misdiagnosis or unnecessary treatment. This article concisely focuses on the development of a systemic flow of events to come to the proper treatment of the xerostomia and halitosis.
