  • Objectives This scoping review aimed to investigate the domestic clinical research trends of motion-style acupuncture treatment (MSAT), identify diseases and symptoms for which MSAT is used, summarize specific methods of MSAT, and suggest the direction of future studies. Methods The study was conducted in accordance with a previously specified methodology, using the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) checklist. We searched nine electronic databases for studies on MSAT reported till March 21, 2022. The search terms were 'kinematic acupuncture,' 'MSAT,' 'motion style acupuncture,' and 'motion style treatment.' Results A total of 29 studies were included in our analyses; of them, 23 (79.3%) were before-after studies. Lumbosacral disease was the most common for which MSAT was applied (n=16). The frequency and duration of treatments differed depending on the researchers, and local acupoints (including ashi points) were used in 22 (75.9%) studies. In most cases, the method of mobilizing the joint or stretching the muscle in the disease area was used after inserting the acupuncture; however, in 7 studies, gait exercise was used. Most studies used MSAT in combination with other treatments. Conclusions This study supports the direction of future research by presenting the methodological applications of MSAT. To increase its clinical applicability, studies with a high level of evidence investigating the application to various body part, standardization and safety of MSAT are necessary.

  • With the development of virtual and augmented reality technologies, the metaverse, a digital world that provides an immersive feeling like the real world, is overgrowing. Many IT companies such as Naver, Facebook (Meta), and NVIDIA are developing innovative technologies and launching the Metaverse platform and related products on the market. However, even though it is a new business in which many global big tech companies are aggressively investing, the results are not yet precise compared to the market expectations, and the rate of increase in the number of users is gradually slowing down. This can be attributed to the lack of consideration and understanding about how to grow the metaverse ecosystem and operate & harmonize various users/components from the time the metaverse platform was designed. In order to propose a better solution to these problems, this study adopts the yin-yang and five elements theory, which was created to understand the operation logic and logic of the human world for thousands of years. This research would like to propose a theory of double lines-five elements by defining two essential spaces of the metaverse platform, online and offline, and five essential elements constituting the metaverse platform. This study intends to provide a theoretical lens on how to design and operate a platform through the double lines and five elements theory and the concept of coexistence and polarity between the five elements.

  • Objectives : This study aims to assess the impact of acupotomy on migraine through an examination of clinical studies conducted since 2015. Methods : We conducted a comprehensive search for randomized controlled trials (RCTs) and non-randomized controlled trials (nRCTs) related to acupotomy treatment for migraine, utilizing five Korean online databases (OASIS, Science ON, DBPIA, KISS, RISS), as well as four foreign online databases (CNKI, PubMed, EMBASE, Cochrane Library). We identified a total of 10 relevant studies for analysis. Participants characteristics, treatment points, combination treatments, treatment cycles or frequencies, evaluation indices, efficacy, and adverse events were analyzed. The risk of bias in the 10 RCTs was assessed using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0). Results : A total of 931 participants were included in 10 studies. In the intervention group, the average duration of migraine morbidity ranged from 15.5±4.5 months to 15.9±4.2 years. Six studies based their diagnoses on the International Classification of Headache Disorders (ICHD), while five studies relied on Chinese diagnostic criteria. All studies specified the treatment area as the region exhibiting tenderness or induration on the head and neck. Treatment cycles ranged from a minimum of 2 days to a maximum of 1 week, with the number of days per treatment course varied from 5 days to 4 weeks. The diameter of acupuncture needles used varied between 0.3 mm and 1 mm. Of the eight studies specifying needle length, the shortest was 20 mm, and the longest was 40 mm. A total of eight evaluation indices were employed, with total efficacy rate (TER) and visual analogue scale (VAS) being the most frequently used. Statistically, all intervention groups showed more significant results compared to the control groups. Adverse events were reported in only two studies within the intervention group. Overall, the risk of bias assessment for the selected RCTs ranged from 'some concerns' to 'high risk of bias.' Conclusions : This study showed that acupotomy treatments for migraine were effective.

Methods: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) Group's key questions (PICO) for systematic reviews, a literature search was conducted from January 1, 2020 to June 30, 2023 using the "AND" search formula. The databases used were Korea DB: RISS, SCIENCEON, and KoreaMed, and International DB: PubMed, CINAHL, and Embase. Results: Among a total of 22 selected articles, 4 studies were published in korea journals: 3 were survey studies (75.0%), 1 was an analysis study (25.0%), and 18 studies were published in international journals. Through a literature review, we confirmed the differences in difficulties between PwD (People with Disability) and PwoD (People without Disability) in the COVID-19 situation, differences by disability type, and post-COVID-19 impact. In order to examine this systematically and objectively, the results were examined by dividing them, which are components based on the International Classification of Functioning, Disability and Health (ICF). Conclusion: In order to respond well to crises and establish effective health policies in similar pandemic situations in the future, understanding and exploration of more diverse types and areas of disability are necessary. In addition, the development and application of appropriate health education and health promotion programs for disability type and ICF component area are required. In addition, it is necessary to develop and apply appropriate health education and health promotion programs tailored to the type of disability and ICF component area.

  • Software as a Service (SaaS) has become one of the fastest-growing software business models in recent years. Even during the economic downturn following the pandemic, the SaaS business has emerged as a crucial model for IT companies. The revenue structure of SaaS, which is based on the subscription economy model, ensures that users pay only for the services used. In other words, SaaS operates on a subscription-based billing model, thus providing subscribers access to software uploaded to cloud computers via the Internet. This study aimed to explore the manner by which software-solution firms have to counteract the decline in profit and loss sales caused by changing their business-model orientation from on-premise deployment software to subscription-based software. Additionally it analyzes a method for selecting a subscription-based pricing model and rapidly recovering the investment costs via quantitative business-viability assessment. By calculating subscription fees via a more quantitative business-viability evaluation instead of focusing on conventional business-planning methods that rely on qualitative methods, companies are expected to be equipped in providing services to customers at reasonable costs. This strategy will facilitate them in leading emerging growth sectors.

  • The present study examines the global pitch characteristics in Mandarin and Korean produced by twenty-two bilingual speakers of the two languages. An acoustic experiment was conducted in which a script of the story Northern Wind and the Sun was produced in both Korean and Mandarin at self-controlled fast and slow rates. It finds that Mandarin, a tonal language, is produced with neither wider pitch range nor overall higher pitch and therefore suggests that tonal languages may not necessarily be produced with wider or higher global pitch than non-tonal languages. A comparison of L1 and L2 speech reveals that significant pitch range reduction and global pitch lowering are observed only in the female native Mandarin speakers' L2 Korean. In contrast, a pitch range remains comparable in L1 and L2 speech produced by the male native Mandarin speakers as well as in L1 and L2 speech produced by the male and female native Korean speakers. It further finds gender effect but no speaking rate effect on pitch peak and valley manipulation in changing global pitch ranges. Findings of this study are not in total agreement with previous studies that claim an overall narrow pitch range to be the most essential characteristics of L2 intonation patterns. The observation that the native Korean speakers produced neither pitch range reduction nor overall pitch lowering in L2 Mandarin may be due to their meta-linguistic awareness of the importance of pitch production in a tonal language. L2 fluency seems to play a role in such a way that advanced-level L2 speakers tend to produce more native-like global pitch patterns.

  • It is well-known that a meta-stable fcc bulk Fe has an antiferromagnetic (AFM) ground state and could be synthesized by growing Fe on a proper fcc metal substrate. In this study magnetism of Fe monolayers on nonmagnetic fcc transition metal (Cu, Rh, Pd, and Ag) (001) surfaces has been investigated using the all-electron full-potential linearized augmented plane wave method. The Fe monolayers on Rh(001) and Pd(001) surfaces were calculated to be stabilized in an AFM state, whereas the Fe monlayers on Cu(001) and Ag(001) surfaces are stabilized in a ferromagnetic (FM) state. Noting that Cu and Ag have the smallest and largest lattice constants and the fcc bulk Fe with a larger lattice constant is getting stabilized in a ferromagnetic state, it is unexpectable and interesting. The calculated magnetic moments of the Fe atoms on Cu, Rh, Pd, and Ag(001) surfaces are 2.811, 2.945, 2.987, and 2.990 $_{{\mu}B}$ in FM states and 2.624, 2.879, 2.922, and 3.001 $_{{\mu}B}$ in AFM states.

  • This study examined the possibility to extract potential alteration zones and lithologic information based on ASTER band ratio techniques for mineralized area located in ${\ddot{O}}v{\ddot{o}}rkhangai$ province, Mongolia, and the effectiveness of remote sensing as a preliminary exploration tool for mineral exploration was tested. The results of ABRLO, PBRLO, and PrBRLO models indicated that the detection of argillic zone requires the verification of the samples to verify hydrothermal alteration minerals as clay minerals can formed by weathering process, whereas phyllic-propylitic zones were considerably related to the spatial distribution of the intrusive bodies, geological structures, and ore distribution. QI and MI results showed that QI is more useful for sedimentary rocks such as conglomerate and sandstone than meta-sedimentary like quartzite, and MI faced relatively uncertain in detection of felsic or mafic silicate rocks. QI and MI may require additional geologic information such as the characteristics of samples and geological survey data to improve extraction of lithologic information, and, if so, it is expected that remote sensing technique would contribute significantly as a preliminary geological survey method.

  • Objective : The aim of this study was to review systemically clinical trials on the effectiveness and safety of herbal medicines in the treatment of osteoarthritis. Methods : Computerized literature searches were carried out on seven electronic databases, and hand-searching on some chinese medical journals in library of Kyung Hee Medical Center. Trial data were extracted in a standardized, predefined manner and assessed independently. Results : 1. Thirty reports of clinical trials and two reports of meta-analyses concerning herbal medicine were collected and reviewed. Among these reports three medical herbs were applied as topical medicine and others as internal medicine. 2. The western studies established NSAIDs or placebo as their control group. Five chinese reports established formulated herb pill(Ruanshnagshenjin pill) as their control group and Six did not establish a control group at all. 3. ACR was the most highly used diagnostic criteria in the western studies while the Chinese used their official criteria established by their government or the criteria of their text books. 4. 20 reports chose the Lequesne functional index, SHAQ, WOMAC OA index, AIMS, and their own unique scoring system as the criteria of analysing the effect. Others chose clinical symptoms, articular functions, and lab finding as their criteria. 5. 7 single herbs and 19 formulated herbs were studied. Among the formulated herbs, Achyranthes japonica was studied in 10 of the studies and Angelica gigantis Radix in 8, making them the most often studied herbs among the studies.
