Semantic network analysis of conflict in Korean society regarding the WHO classification of gaming disorder (disease code 6C51)

Background: In 2018, the World Health Organization (WHO), in its 11th revision of the International Classification of Diseases (ICD-11), classified ‘gaming disorder’ as a disease. As a result, countries are witnessing conflicts among stakeholders with regard to the introduction of the classification. The objective of this analysis is to identify trends of coverage made by major media outlets in Korea concerning the controversy over the introduction of ‘gaming disorder’ like a disease and, through such an analysis, examine how social perceptions have been formulated in Korea. Methods: Semantic network analysis was deployed to examine the semantic structure of messages delivered by the media. The analysis was conducted to identify what semantic structure and issues were pursued by the media with regard to the introduction of ‘gaming disorder’ as a disease in the context of social debates, by looking at the prominent of words in messages delivered by news media, and the interactive structure among these words. Results: In terms of their prevalence, the main keywords in major media reports were ‘addiction’, ‘WHO’, ‘classification’, ‘industry’, ‘code’, ‘domestic’, ‘objection’, ‘gaming industry’, ‘introduce’, ‘gaming disorder’, and ‘Ministry of Culture, Sports and Tourism/MCST’. The structural characteristics of the entire network of media reports were formed around keywords such as ‘addiction’, ‘WHO’, ‘classification’, ‘objection’, ‘industry’, ‘code’, ‘mental disorder’, and ‘backlash’. Words with high eigenvector centrality were ‘addiction’, ‘WHO’, ‘classification’, ‘industry’, ‘domestic’, ‘code’, ‘objection’, ‘introduce’, ‘controversy’, and ‘Ministry of Culture, Sports and Tourism/MCST’. Following CONCOR analysis, a total of four clusters were formed: Cluster 1 for objection, Cluster 2 for consent, Cluster 3 for expected problems, and Cluster 4 for factors for efforts towards conflict resolution. Conclusions: This research explored social perceptions in Korea regarding the issue of the WHO introducing gaming disorder as a disease, by identifying trends of the media coverage through a semantic network analysis of the media’s asymmetrical data. Through this, despite the inevitable introduction of the system to promote public health, it was shown that there is a sharp conflict between the medical and the game industry and related public organizations in Korea.

In addition, this study examines the moderating effect of an environmental worldview regarding green hotel attributes and image, and visit intention. A self-administrated survey will be conducted to collect data. For data analysis, simple descriptive statistics, factor analysis, and SEM will be utilized to confirm causal relationships among projected constructs. The results of this study will help hoteliers and hotel developers to understand what green hotel attributes are important and necessary to build favorable hotel images, and help researchers to develop future research projects relating to environmental hotel attributes and consumer behaviors.&nbsp

Comparison of volume-controlled and pressure-controlled ventilation using a laryngeal mask airway during gynecological laparoscopy

Background: Several publications have reported the successful, safe use of Laryngeal Mask Airway (LMA)-Classic devices in patients undergoing laparoscopic surgery. However, there have been no studies that have examined the application of volume-controlled ventilation (VCV) or pressure-controlled ventilation (PCV) using a LMA during gynecological laparoscopy. The aim of this study is to compare how the VCV and PCV modes and using a LMA affect the pulmonary mechanics, the gas exchange and the cardiovascular responses in patients who are undergoing gynecological laparoscopy. Methods: Sixty female patients were randomly allocated to one of two groups, (the VCV or PCV groups). In the VCV group, baseline ventilation of the lung was performed with volume-controlled ventilation and a tidal volume of 10 ml/kg ideal body weight (IBW). In the PCV group, baseline ventilation of the lung using pressure-controlled ventilation was initiated with a peak airway pressure that provided a tidal volume of 10 ml/kg IBW and an upper limit of 35 cmH2O. The end-tidal CO2, the peak airway pressures (Ppeak), the compliance, the airway resistance and the arterial oxygen saturation were recorded at T1: 5 minutes after insertion of the laryngeal airway, and at T2 and T3: 5 and 15 minutes, respectively, after CO2 insufflation. Results: The Ppeak at 5 minutes and 15 minutes after CO2 insufflation were significantly increased compared to the baseline values in both groups. Also, at 5 minutes and 15 minutes after CO2 insufflation, there were significant differences of the Ppeak between the two groups. The compliance decreased in both groups after creating the pneumopertoneim (P < 0.05). Conclusions: Our results demonstrate that PCV may be an effective method of ventilation during gynecological laparoscopy, and it ensures oxygenation while minimizing the increases of the peak airway pressure after CO2 insufflation. ��� the Korean Society of Anesthesiologists, 2011

High-fidelity 3D Human Digitization from Single 2K Resolution Images

High-quality 3D human body reconstruction requires high-fidelity and large-scale training data and appropriate network design that effectively exploits the high-resolution input images. To tackle these problems, we propose a simple yet effective 3D human digitization method called 2K2K, which constructs a large-scale 2K human dataset and infers 3D human models from 2K resolution images. The proposed method separately recovers the global shape of a human and its details. The low-resolution depth network predicts the global structure from a low-resolution image, and the part-wise image-to-normal network predicts the details of the 3D human body structure. The high-resolution depth network merges the global 3D shape and the detailed structures to infer the high-resolution front and back side depth maps. Finally, an off-the-shelf mesh generator reconstructs the full 3D human model, which are available at https://github.com/SangHunHan92/2K2K. In addition, we also provide 2,050 3D human models, including texture maps, 3D joints, and SMPL parameters for research purposes. In experiments, we demonstrate competitive performance over the recent works on various datasets.Comment: code page : https://github.com/SangHunHan92/2K2K, Accepted to CVPR 2023 (Highlight

Association between Obesity and Physical Fitness, and Hemoglobin A1c Level and Metabolic Syndrome in Korean Adults

BACKGROUND: The purpose of the current study was to investigate the association of obesity level, physical fitness level, hemoglobin A1c (HbA1c) level and metabolic syndrome (MetS) risk factors among Korean adults. METHODS: A total of 557 adults (272 males and 285 females) who underwent medical check-up at local hospital were recruited. In addition to regular health check-up, cardiopulmonary fitness, muscular endurance were measured and their association were analyzed. RESULTS: The prevalence of MetS was 31.7% for males and 23.7% for females. Females with the higher muscular endurance had lower waist circumference, triglyceride level, and HbA1c level than those with the lower muscular endurance. Males with the higher level of cardiopulmonary fitness had lower diastolic blood pressure, lower high-sensitivity C-reactive protein level and higher high density lipoprotein cholesterol level than males with the lower level of cardiopulmonary fitness. Females with the higher level of cardiopulmonary fitness had lower body weight, body mass index, systolic blood pressure, and fasting blood glucose level than females with the lower level of cardiopulmonary fitness. Participants with the higher level of adiposity and the lower level of physical fitness were 5.26 times (95% confidence interval [CI], 2.19 to 12.62), 5.71 times (95% CI, 2.23 to 14.60) more likely to have MetS, respectively, in male and female compared to participants who were neither obese nor have the lower level of fitness. CONCLUSION: This study suggests that maintaining a healthy body weight as well as a certain level of fitness is important for the prevention of MetS.ope

A randomized prospective trial of the postoperative quality of life between laparoscopic uterine artery ligation and laparoscopy-assisted vaginal hysterectomy for the treatment of symptomatic uterine fibroids: clinical trial design

<p>Abstract</p> <p>Background</p> <p>Laparoscopy-assisted vaginal hysterectomy is one of the definite methods for the treatment of symptomatic uterine fibroids with lesser intraoperative bleeding and shorter hospitalization compared with abdominal hysterectomy. However, laparoscopy-assisted vaginal hysterectomy cannot preserve uterus and can show postoperative complications by the change of pelvic structure. Thus, laparoscopic uterine artery ligation has been introduced for relieving the symptoms caused by uterine fibroids in place of hysterectomy. The current study was designed to compare postoperative quality of life between laparoscopic uterine artery ligation and laparoscopy-assisted vaginal hysterectomy, and to evaluate the efficacy of laparoscopic uterine artery ligation which can treat symptomatic uterine fibroids with the preservation of uterus.</p> <p>Methods and design</p> <p>Patients enrolled the current study are randomized to laparoscopic uterine artery ligation or laparoscopy-assisted vaginal hysterectomy. The primary outcome is to compare postoperative quality of life between laparoscopic uterine artery ligation and laparoscopy-assisted vaginal hysterectomy using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer patients version 3.0. Secondary outcomes are to evaluate the volume reduction of uterus, uterine fibroids and ovaries by the 2 treatments, to compare the improvement of subjective symptoms using 11-point symptom score and postoperative clinical outcomes between laparoscopic uterine artery ligation and laparoscopy-assisted vaginal hysterectomy, and to investigate the improvement of postoperative vaginal bleeding by laparoscopic uterine artery ligation.</p> <p>Discussion</p> <p>Among treatment methods for symptomatic uterine fibroids with the preservation of uterus, laparoscopic uterine artery ligation is expected to have the efficacy like uterine artery embolization, which appeared to be safe for routine use with symptomatic relief. The current study fully recruited in June 2008 and the results will be available in June 2009. If there is no difference of postoperative QOL between laparoscopic uterine artery ligation and laparoscopy-assisted vaginal hysterectomy for the treatment of symptomatic uterine fibroids, the comparison of quality of life between laparoscopic uterine artery ligation and uterine artery embolization will be also needed as a surgical treatment for preserving uterus.</p> <p>Trial registration</p> <p>Current Controlled Trials ISRCTN76790866</p

In situ rumen degradability characteristics of rice straw, soybean curd residue and peppermint (Mentha piperita) in Hanwoo steer (Bos Taurus coreanae)

This study was intended to evaluate in situ rumen degradability characteristic of soybean curd residue (SCR) and peppermint compared to rice straw, which are used as a functional feed source for beef cattle for high quality beef production. Two steers were fitted with rumen and duodenum cannulae and in situ degradable and nylon bags were used to assess digestion of rice straw, SCR and peppermint in three replicated experiments. The highly effective dry matter (DM) degradability of peppermint was attributable to the high rate of the a and b fractions. Dry matter disappearance rate of SCR after 48 h was higher (p &lt; 0.05) than that of peppermint. Based on DM disappearance, SCR showed the highest digestibility (p &lt; 0.05). Crude protein disappearance (%) was higher for SCR and peppermint than rice straw (p &lt; 0.05), and neutral detergent fibre disappearance (%) was higher for SCR (p &lt; 0.05). Soybean curd residue and peppermint have great nutritive values as feed sources for ruminants, and using SCR and peppermint would have possibilities for efficient and functional livestock production.Keywords: Beef cattle, digestibility, effective degradability, soybean curd residue, peppermintAfrican Journal of Biotechnology Vol. 12(14), pp. 1710-171

Avian influenza virus transmission is suppressed in chickens fed Lactobacillus paracasei expressing the 3D8 single-chain variable fragment protein

The 3D8 single-chain variable fragment (scFv) is a mini-antibody sequence with independent nuclease activity that shows antiviral effects against all types of viruses in chickens and mice. In this study, chickens were treated daily with an oral dose of 109 CFU Lactobacillus paracasei (L. paracasei) expressing either a secreted or anchored 3D8 scFv for three weeks. After L. paracasei administration, the chickens were challenged with avian influenza virus (AIV). From each experimental group, three chickens were directly infected with 100 µL of 107.5 EID50/mL H9N2 AIV and seven chickens were indirectly challenged through contact transmission. oropharyngeal and cloacal swab samples were collected at 3, 5, 7, and 9 days post-inoculation (dpi) from AIV-challenged chickens, AIV Shedding titres were measured by quantitative real-time PCR. Contact transmission in the chickens that were fed 3D8 scFv-secreting L. paracasei showed a significant reduction in viral shedding when compared with other groups. These results suggest that L. paracasei secreting 3D8 provides a basis for the development of ingestible antiviral probiotics with activity against AIV
