Use of work-related communication technology outside regular working hours and work-family conflict (work interference with family and family interference with work): results from the 6th Korean working conditions survey

Background: Recently, use of work-related communication technology - smartphones, tablets, and laptops - is increasing rapidly by development of technology with the coronavirus disease 2019 pandemic. Some studies have suggested that work-related communication technology has a significant link with work-family conflict (WFC) but these studies included only limited number of participants and lacked essential covariates. Therefore, this study analyzes this association using large representative data sample and selected waged workers who were married-couples with children. Methods: This study was conducted based on data from the 6th Korean Working Conditions Surveys (KWCS). A total of 17,426 waged workers having a marriage partner and one or more children were selected. Logistic regression analysis was performed to determine whether WFC was associated with communication technology use. The odds ratios (ORs) for WFC were stratified by sex and working hours. Results: In fully adjusted model, WFC was higher those who used communication technology outside regular working hours compared with those who did not use it (OR: 1.66; 95% confidence interval [CI]: 1.39-1.97). When stratified by sex and working hours, the effect was greater in women than in men (OR: 1.79; 95% CI: 1.42-2.26 vs. OR: 1.52; 95% CI: 1.17-1.97) and women who worked over 52 hours per week had the highest OR (3.40; 95% CI: 1.25-9.26). Conclusions: This study revealed that the work-related communication technology use outside regular working hours was associated with WFC. The association were greater among those having longer working hours and female workers. These results suggest that appropriate policy should be implemented to reduce working hours and right to disconnect after work, particularly in female workers

Endoscopic treatment for rectal neuroendocrine tumor: which method is better?

Recently, research on rectal neuroendocrine tumors (NETs) has increased during the last few decades. Rectal NETs measuring 10 mm, suctioning is not possible due to fibrosis in the lesion, or when the snaring for modified endoscopic mucosal resection does not work well

Orthodontic treatment of gummy smile by maxillary total intrusion with a midpalatal absolute anchorage system

This article describes the orthodontic treatment of a 31-year-old Korean female patient with gummy smile and crowding. The patient showed excessive gingival display in both the anterior and posterior areas and a large difference in gingival heights between the anterior and posterior teeth in the maxilla. To correct the gummy smile, we elected to intrude the entire maxillary dentition instead of focusing only on the maxillary anterior teeth. Alignment and leveling were performed, and a midpalatal absolute anchorage system as well as a modified lingual arch was designed to achieve posterosuperior movement of the entire upper dentition. The active treatment period was 18 months. The gummy smile and crowding were corrected, and the results were stable at 21 months post-treatment.OAIID:oai:osos.snu.ac.kr:snu2013-01/102/0000004298/7SEQ:7PERF_CD:SNU2013-01EVAL_ITEM_CD:102USER_ID:0000004298ADJUST_YN:YEMP_ID:A072100DEPT_CD:852CITE_RATE:.537FILENAME:hongyk-maas-gummy0smile-kjo-2013.pdfDEPT_NM:치의과학과SCOPUS_YN:YCONFIRM:

부정교합이 성인 여자대학생의 자존감에 미치는 영향

Objective: The purpose of this study was to evaluate the effects of malocclusion on the self-esteem of female university students. Methods: The subjects were composed of 67 female university students who showed Class I molar relation, no missing or supernumerary teeth and has had no orthodontic treatment experience. Each subject was evaluated with Rosenberg`s Self-esteem Scale to measure the level of self-esteem and also evaluated the degree of anterior crowding and lip protrusion through model analysis and cephalometric soft tissue profile analysis. Results: The results showed that a protrusive profile and crowding of upper anterior teeth had significant reducing effects on the level of self-esteem. The protrusion and crowding groups showed no significant differences in self-esteem between groups. Conclusions: Malocclusion had significant negative effects on the self-esteem of female university students. Further research to investigate the negative psychological influence of malocclusion and the education of lay people about this influence is necessary.

Age group characteristics of clinical features and use of epinephrine in children with anaphylaxis who visited the emergency department

Purpose Diagnosis of anaphylaxis depends on clinical manifestations and a high index of suspicion, and a misdiagnosis can lead to a preventable death. We aimed to investigate age group characteristics of clinical features and epinephrine use in children with anaphylaxis who visited the emergency department (ED). Methods We performed a retrospective chart review of 138 children who visited a tertiary care hospital ED from January through December 2018, and were discharged with anaphylaxis as the diagnosis. Anaphylaxis was defined according to the National Institutes of Allergy and Infectious Disease criteria. The children were divided into 4 age groups; infants (< 1 year), preschoolers (1-5 years), schoolers (6-11 years), and adolescents (12-18 years). Clinical features and epinephrine use were compared among the age groups. Results Of the 138 children with presumed anaphylaxis, 108 met the criteria. The most common cause was food (74%), followed by drugs (10.2%). Epinephrine was used in 82 children (75.9%). The infants and preschoolers reported less frequent cardiovascular symptoms (0%-3.6% vs. 26.5%, P = 0.020) and epinephrine use (33.3%-70.9% vs. 91.2%, P = 0.037) compared to the adolescents. The former 2 age groups reported food as triggers more frequent, and often reported food-associated and respiratory or gastrointestinal symptoms. Conclusion Infants and preschoolers with anaphylaxis may undergo less frequent cardiovascular symptoms and epinephrine use compared to adolescents. This feature prompts to increased epinephrine use in the former age groups even without age-adjusted hypotension

Self-care use patterns in the UK, US, Australia, and Japan: a multinational web-based survey

AbstractBackgroundThe trend toward patient- or consumer-centered healthcare has been accelerated by advances in technology, consumer empowerment, and a shift from infectious to chronic diseases. The purpose of this study was to examine the growing self-care market by analyzing self-care patterns.MethodsWe conducted a cross-sectional, web-based survey involving adults from nine major cities in the UK, the USA, Australia, and Japan. This study examined the extent and frequency of self-care, self-care expenditure, sources of self-care information, and reasons for self-care in each country.ResultsThe results showed that the prevalence of self-care was highest in Japan (54.9%), followed by the UK (43.1%), the USA (42.5%), and Australia (40.4%). The primary reason for practicing self-care was “to manage my healthcare myself” (cited by 45.7%, 59.5%, 49.2%, and 4.1% of participants in Australia, Japan, the UK, and the USA, respectively). Significant linear associations were observed between age and the prevalence of self-care in all countries (p<0.05), indicating that self-care prevalence decreased with age in the UK, the USA, and Australia, and increased with age in Japan. The frequency with which self-care was practiced was positively correlated with age in the USA (p<0.05), Australia (p<0.01), and Japan (p<0.05). In addition to acquaintances, internet search engines and information obtained from pharmacies were considered reliable and widely used sources of self-care information.ConclusionWhen developing self-care products or services, healthcare providers and policymakers should consider self-care patterns

Non-thermal atmospheric pressure plasma-conditioned root dentin promotes attraction and attachment of primary human dental pulp stem cells in real-time Ex Vivo

This study investigated if non-thermal atmospheric pressure plasma (NTAPP) treatment of root dentin surfaces promotes human dental pulp stem cell (hDPSCs) adhesion. Freshly extracted human single-rooted teeth (n = 36) were decoronated and cut (first vertically, then horizontally) into root dentin slices (3 mm thick). Primary hDPSCs cultures were seeded onto slices randomly assigned to pretreatment groups (n = 9/group): NaOCl (1.5%), EDTA (17%) then NTAPP (Group I); NaOCl then NTAPP (Group II); NaOCl then EDTA (Group III); and NaOCl alone (Group IV). Cell viability and proliferation were measured using MTT assay with log-linear statistical analysis. Cell attachment and spreading morphologies on dentin slices (n = 3/group) were examined through scanning electron microscopy. Early cell adhesion events and subcellular activities were observed in real time by live-cell imaging through holotomographic microscopy. Cell viability and proliferation were significantly higher on NTAPP-treated dentin (p \u3c 0.05), without interactions with EDTA (p \u3e 0.05). The attachment, spreading, extensions and multiple layers of hDPSCs were heightened on NTAPP-treated dentin. Cell adhesion, spreading, and dentinal tubule penetration were hastened on NTAPP-treated dentin surfaces in real-time, with elevated subcellular activities and intracellular lipid droplet formation. NTAPP-treated root dentin surfaces support enhanced cellular responses, potentially promoting pulp-dentin regeneration
