Purpose: This study’s aim was to confirm the importance and performance of the clinical practice of nurses working in the general wards of a tertiary hospital and to analyze their educational needs.Methods: The study employed a descriptive research design, and a self-reported questionnaire was developed and used for nurses in a tertiary hospital. Data were collected from July 22 to July 29, 2022, analyzed by an independent t-test, paired t-test, and one-way ANOVA for the importance and performance of each clinical nursing practice according to general characteristics, and then a post hoc verification was performed by Scheffé’s test. An Importance-Performance Analysis and Borich needs assessment model were used to analyze clinical nursing education needs.Results: Clinical nursing practice performance showed a significant difference according to length of total clinical career, time working in current department, and preceptor experience. According to the results of the Importance-Performance Analysis, neurological evaluation, and nursing intervention, artificial respirator and high-flow oxygen inhalation nursing, chemotherapy, emergency nursing, and cardiopulmonary resuscitation were identified as belonging to the “concentrate here” quadrant. All these items ranked in the top 10 in the Borich needs assessment model.Conclusion: Based on these results, the current education system should be reviewed, and short and long term education strategies based on educational needs should be established to strengthen the competence of nurses.

Purpose: The aim of this study was to determine burnout and its related factors among nurses working at a tertiary hospital, who had experienced caring for patients with confirmed and suspected coronavirus disease 2019 (COVID-19), including those with severe and critical conditions during the outbreak.Methods: Responses of 129 nurses, who worked in a tertiary hospital in Daegu, which was designated as a special control area for infectious disease in Korea, were analyzed. Data were collected from November 1, 2020 to December 14, 2020 using self-report questionnaires. Analysis was performed using t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression.Results: Burnout did not show any statistically significant differences in age, sex, marital status, total length of clinical experience, and the department at the time of caring for COVID-19 patients. Compassion fatigue, stress, depression, and anxiety were positively related with burnout, and compassion satisfaction was negatively related with burnout. In regression analysis, compassion satisfaction, compassion fatigue, and stress were confirmed as the predictive factors of burnout.Conclusion: The study results suggest that compassion satisfaction, compassion fatigue, and stress could play an important role in reducing burnout among tertiary hospital nurses during infectious disease outbreaks.

Background: Compared with conventional closed therapy, acupotomy has the advantages of lower cost, convenient application, and better single and long-term effects. The aim of this study was to explore the clinical effect of acupotomy in the treatment of Tarsal Tunnel syndrome.Methods: There were 80 patients enrolled into the study who were randomly assigned to either the acupotomy or closed therapy group, with 40 patients in each group. The acupotomy group was treated once every 6 days, on 3 occasions for the duration of treatment, and the closed therapy group was treated twice a week, for 3 weeks as the course of treatment. The effects of treatment were analyzed and evaluated according to the standard of curative effect.Results: The “cure rate” of the number of patients in the acupotomy group whose symptoms had completely disappeared (13 patient out of 39) was higher than the closed therapy group (1 patient out of 39), and this difference was significant (p < 0.01). The number of patients in the acupotomy group who did not benefit from the therapy (5 patients) was significantly lower than the closed therapy group (15 patients; p < 0.05). The total number of patients in the acupotomy group who benefitted from the therapy (34 patients) resulted in an effective rate of 87.18%, which was higher than the closed therapy group (24 patients; 61.53%). The difference was statistically significant (p < 0.05).Conclusion: Acupotomy is effective in the treatment of Tarsal Tunnel syndrome, was superior to traditional closed therapy, and is worthy of clinical application.

Purpose This study examined both American and Korean consumers’ motivation to share marketer-generated content (MGC) on Facebook and how these motives are related to the frequency of various types of sharing activities and the frequency of sharing various types of MGC. Design/methodology/approach An online survey was conducted in the US and Korea. Findings The findings demonstrated that both American and Korean consumers share MGC for several reasons: liking/helping the brand, self-presentation/social interaction, economic rewards, and entertainment. In addition to these four motivations, Korean consumers also share MGC with others to offer information that may be of use to them. These different types of motivations were associated with the frequency of sharing MGC directly from Facebook brand pages, of re-sharing what Facebook friends shared first, of adding comments when sharing, and of sharing different types of MGC differently. We found similarities and differences in the patterns of these relationships between the US and Korea. Originality/value Although many studies on electronic word of mouth (eWOM) have examined consumers’ motivations for providing consumer-generated content, research on consumer motivations to forward marketer-generated content is scarce. Additionally, earlier work examined the influences of motivation on sharing in general and on a certain type of MGC. Our findings that focused on various types of motivations to share MGC, and their influences on various types of MGC and specific types of sharing activities can provide a more complete picture than what was previously available in the eWOM literature. Further, by comparing American consumers’ motivations to share MGC on SNSs and their influences on sharing activities with those of Korean consumers, this study contributes to building a body of cross-cultural studies on consumer sharing of MGC.

Occult residual disease in remnant tissues could be the cause of tumor relapse. To identify signal molecules and target cells that may be indicative of occult residual disease within a remnant microenvironment, proximal resection margin tissues of gastric cancers were used, as these correspond to the nearest remnant tissues after gastrectomy. Increased miR-146b-5p in the remnant microenvironment was determined to be a strong risk factor for tumor relapse and poor survival rate. NOVA1, a target gene of miR-146b-5p, was decreased in remnant tissues of patients with a poor prognosis. NOVA1 was enriched in stromal spindle cells such as fibroblasts within normal tissues. In non-neoplastic inflammation, such as gastritis, NOVA1 was highly enriched in T lymphocytes and stromal spindle cells, while expression of this protein was frequently decreased in those types of cells within gastric cancer tissues. Particularly, decreased NOVA1 in T cells within the gastric cancer tissues was correlated with decreased FOXP3-positive regulatory T cells and was associated with poor patient prognosis. In vitro analysis showed that the NOVA1 gene was inhibited by miR-146b-5p. In immune cells as well as stromal spindle cells, decreased NOVA1, possibly inhibited by miR-146b-5p, is a candidate biomarker predicting poor prognosis of gastric cancer patients and is also a biomarker of occult residual disease in remnant tissues after gastric cancer removal.

Employing regulatory focus theory, we explored how consumer regulatory focus interacts with 2 characteristics of a consumer review—review valence and claim type—to influence consumers' perceived usefulness of the review. To this end, we conducted an experiment with 126 college students as participants. The results showed that promotion-focused consumers perceived a positive review to be more useful than did prevention-focused consumers, whereas prevention-focused consumers perceived a negative review as more useful than did promotion-focused consumers. We also found that promotion-focused consumers perceived an evaluative review as more useful than did prevention-focused consumers. Unexpectedly, however, both promotion- and prevention-focused consumers perceived a factual review to be highly useful.

A slew-rate control method of LCD driver ICs is introduced to increase uniformity between adjacent driver ICs and reduce power consumption. The slew rate of every voltage follower is calibrated by a feedback algorithm during the non-displaying period. Under normal operation mode, the slew rate is dynamically controlled for improving power efficiency. Experimental results show that the power consumption is reduced by 16% with a white pattern and by 10% with a black pattern, and display defects are successfully eliminated.

DNA methylation change is known to play a crucial role in early gastric carcinogenesis. The present study aimed to identify and validate the correlation between differentially methylated regions (DMRs) and the subtypes of early gastric cancers (EGCs). Illumina Infinium methylation assay (IIMA; 450K BeadChip kit) was performed on fresh tumor and non‑tumor tissues of 12 EGCs to screen the methylation status of 450,000 CpG sites. To evaluate the significance of DNA methylation in each histologic subtype, pyrosequencing assay (PA) was performed on 38 EGCs (18 intestinal-, 12 mixed- and 8 diffuse-type) using 12 genes selected from the screening. Between tumors of the intestinal-type (n=6), and diffuse- (n=4) plus mixed-types (n=2), 169 regions showed significant differences (intensity>3,000, Δβ>0.2) in IIMA. Hierarchical clustering using the 169 DMRs revealed distinct separation between the two groups. In PA using 12 selected genes from the IIMA results, the aberrant methylation statuses of DVL2 (p=0.0186) and ETS1 (p=0.0222) were significantly related to diffuse- and mixed-types rather than the intestinal-type, while C19orf35 (p=0.019) and CNRIP1 (p=0.0473) were related to the diffuse‑type rather than intestinal‑type, and GAL3ST2 (p=0.0158) and ITGA3 (p=0.0273) were related to the mixed-type rather than the other two types. The methylation of other genes, CLIP4, XKR6, CCDC57, MAML3 and SDC2, was related with age, tumor location, or Helicobacter infection rather than the histologic subtype. Aberrant DNA methylation of certain genes may be independently involved in each histologic subtype of EGC. Furthermore, mixed-type EGCs may be a distinctive histologic subtype based on the different subset of DMRs compared to those of other subtypes.

Purpose – The purpose of this paper is to investigate the content of food advergames and the nutritional quality of foods promoted in those advergames with the presence of child visitors. Design/methodology/approach – This study integrates three different sources of data, first, characteristics of the audience from internet audience measurement metrics; second, an analysis of food advergame content; and third, an analysis of the dietary quality of the foods in advergames. Findings – The results show that 83.2 percent of the total 143 advergames are sponsored by CFBAI participating companies and 79.5 percent of the total 44 advergames reaching children are sponsored by those companies. About 87 percent of the advergames reaching children do not include age limit specification. By contrast, about 71 percent of the advergames reaching children include ad breaks and about half of the advergames reaching children include healthy lifestyle information. Compared to the total, advergames reaching children seem to have a higher level of brand integration. Moreover, most foods that the advergames promote are classified as unhealthy. Finally, the results show that ad breaks and number of brand identifiers are the two significant predictors of food advergames with child unique visitors. Originality/value – Despite the increased attention to and scrutiny of innovative and interactive food marketing targeting children, little is known about the extent to which such techniques actually reach children, nor about the content and nutritional quality of foods they promote. This study attempts to fill in the gap by focussing on food advergames.

This paper describes a voltage-mode transmitter with an AC-/DC-coupled equalizer. A dual-loop regulator controls the tap-weight coefficient for the DC-coupled equalizer while maintaining the output matching condition. An AC-coupling technique is employed to enhance the edge rate and reduce the burden of the DC-coupled equalizer. The transmitter also supports the ability to add a DC differential voltage offset into the output signal so that the voltage margin of the link can be measured. The transmitter was fabricated using a 0.13-um CMOS technology. When 240- mVPP, 5.2-Gb/s data are sent over 20-inch FR4 channels, the eye of the received data has a voltage margin of 60 mV and a peak-to-peak jitter of 40 ps. The proposed transmitter consumes 5.86 mW from a 1.2-V supply while operating at 5.2 Gb/s.

Given a simple rectilinear polygon P in the xy-plane, a roof over P is a terrain over P whose faces are supported by planes through edges of P that make a dihedral angle @p/4 with the xy-plane. According to this definition, some roofs may have faces isolated from the boundary of P or even local minima, which are undesirable for several practical reasons. In this paper, we introduce realistic roofs by imposing a few additional constraints. We investigate the geometric and combinatorial properties of realistic roofs and show that the straight skeleton induces a realistic roof with maximum height and volume. We also show that the maximum possible number of distinct realistic roofs over P is ((n-4)/2@?(n-4)/4@?) when P has n vertices. We present an algorithm that enumerates a combinatorial representation of each such roof in O(1) time per roof without repetition, after O(n^4) preprocessing time. We also present an O(n^5)-time algorithm for computing a realistic roof with minimum height or volume.

Drawing on the impression management theory, this study examined the effect of online media platforms, social network sites (SNSs) versus non-SNSs, on the intention to join a cause. The online experimental study discovered that the SNS was more effective in increasing the intention to join a cause than the non-SNS. The findings also demonstrated the mediating role of the perceived visibility of joining the cause and the moderating role of public self-consciousness on this effect. Further, self-cause image congruence positively influenced the intention to join the cause, while it did not moderate the effect of online media platforms.

Objective This study aimed to examine the distribution of working hours and the association between working hours and depressive symptomatology using representative data from a national, population-based survey. Method Data came from the fourth Korean National Health and Nutrition Examination Survey (2007–2009), which employed a systematic, stratified cluster-sampling method. We used logistic regression procedures to estimate the importance of weekly working hours as a predictor of depressive symptomatology. Results The prevalence of depressive symptomatology was 10.2%. The work week, which averaged 48.3 hours for the sample as a whole, was longer for men (49.8 hours) than women (45.3 hours), and 12.1% of respondents were engaged in shift work. In logistic regression analyses, compared to those working

PurposeThe purpose of this paper is to explore how the facial expression of the reviewer's avatar interacts with the valence of the consumer review to influence consumer purchase decisions.Design/methodology/approachA 2 (facial expression of the reviewer's avatar)× 2 (valence of the consumer review) between‐subjects online experimental design was used.FindingsIt was found that when the consumer review was positive, participants exposed to the reviewer's angry‐looking avatar were more likely to attribute the review to the product's performance than those exposed to the happy‐looking avatar. The causal attribution toward product performance, in turn, influenced the strength of intention to purchase the brand positively. When the consumer review was negative, however, there were no differential effects between the happy‐looking and the angry‐looking avatars.Originality/valueThis study contributes to the literature on consumer reviews by identifying an important source characteristic that consumers consider when processing consumer reviews – the facial expression of the reviewer's avatar.

Drawing on the theoretical framework of consumer inferences of marketer motives, we explore consumer responses to different types of product recommendation provided by an e-commerce website (i.e. recommendation systems, RS). The findings demonstrate that RS for alternative brands only are most likely to lead to the consumer inference of a consumer-serving motive, followed by RS for both alternative brands and additional products, and RS for additional products only. In turn, the consumer inference of a consumer-serving motive has a positive influence on attitude towards the website. However, the consumer inference of a firm-serving motive does not mediate the effect of RS type on attitude towards the website. Further, the effect of RS type on attitude towards the website occurs only for consumers low in interpersonal trust. Theoretical and managerial implications are also discussed.

Background Periodontitis is a chronic and long-lasting low-grade inflammatory disease. Numerous studies have shown that the severity of periodontitis rose when there was an increase in the amount of smoking or alcohol consumption. However, as periodontitis known as a chronic disease, it is important to consider not only the amount but “duration” with frequency i.e., rates, of smoking or drinking. This study assessed impacts of the amount and duration of smoking and drinking on periodontal health in Korean adults. We also investigated whether or not there is an interactive effect of smoking and drinking on periodontal health. Methods Under a cross-sectional study design, we used data from the fourth and fifth the Korean National Health and Nutrition Examination Survey (KNHANES) sessions (2008–2010). A total of 18,488 subjects (over 19 years) answered both smoking and drinking status and were given the periodontal examination. Periodontal health status was determined by the community periodontal index (CPI) developed by the World Health Organization (WHO). According to the WHO guidelines, if a participant’s CPI was 3 or larger, we classified the person as a case of periodontitis. Participants with a CPI

This paper describes a 4-Gb/s receiver circuit for a low-swing ground-referenced differential signaling system. The receiver employs a common-gate level-shifter and a continuous linear equalizer which compensates inter-symbol-interference (ISI) and improves voltage and timing margins. A bias circuit maintains the bias current of the level-shifter when the common level of the input signal changes. The receiver is implemented with a low-power 65-nm CMOS technology. When 4-Gb/s 400mVp-p signals are transmitted to the receiver through the channel with the attenuation of -19.7dB, the timing margin based on bit error rate (BER) of is 0.48UI and the power consumption is as low as 0.30mW/Gb/s.
