autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field.

We report highly bright and efficient inverted structure quantum dot (QD) based light-emitting diodes (QLEDs) by using solution-processed ZnO nanoparticles as the electron injection/transport layer and by optimizing energy levels with the organic hole transport layer. We have successfully demonstrated highly bright red, green, and blue QLEDs showing maximum luminances up to 23,040, 218,800, and 2250 cd/m(2), and external quantum efficiencies of 7.3, 5.8, and 1.7%, respectively. It is also noticeable that they showed turn-on voltages as low as the bandgap energy of each QD and long operational lifetime, mainly attributed to the direct exciton recombination within QDs through the inverted device structure. These results signify a remarkable progress in QLEDs and offer a practicable platform for the realization of QD-based full-color displays and lightings.

Fingertip skin-mimicking ferroelectric skins sensitively detect and discriminate static/dynamic pressure and temperature.

The rate of detection of thyroid nodules and carcinomas has increased with the widespread use of ultrasonography (US), which is the mainstay for the detection and risk stratification of thyroid nodules as well as for providing guidance for their biopsy and nonsurgical treatment. The Korean Society of Thyroid Radiology (KSThR) published their first recommendations for the US-based diagnosis and management of thyroid nodules in 2011. These recommendations have been used as the standard guidelines for the past several years in Korea. Lately, the application of US has been further emphasized for the personalized management of patients with thyroid nodules. The Task Force on Thyroid Nodules of the KSThR has revised the recommendations for the ultrasound diagnosis and imaging-based management of thyroid nodules. The review and recommendations in this report have been based on a comprehensive analysis of the current literature and the consensus of experts.

Composites of Si nanoparticles highly dispersed between graphene sheets, and supported by a 3-D network of graphite formed by reconstituting regions of graphene stacks exhibit high Li ion storage capacities and cycling stability. An electrode was prepared with a storage capacity >2200 mA h g(-1) after 50 cycles and >1500 mA h g(-1) after 200 cycles that decreased by <0.5% per cycle.

This research aims to examine the relationships among three components of the physical environment (i.e., décor and artifacts, spatial layout, and ambient conditions), price perception, customer satisfaction, and customer loyalty in the restaurant industry. A total of 279 cases from a survey were used to assess overall fit of the proposed model and test hypotheses using structural equation modeling. The three factors of the physical environment strongly influenced how customers perceived price, and this price perception, in turn, enhanced customer satisfaction level and directly/indirectly influenced customer loyalty. Décor and artifacts were the most significant predictors of price perception among the three components of the physical environment. Furthermore, both price perception and customer satisfaction played significant partial/complete mediating roles in the proposed model. The paper provides potential ways for restaurateurs to increase customer loyalty by improving their understanding of the roles of physical environment, price perception, and customer satisfaction.

As the public is increasingly concerned about environmental issues, green management is rapidly becoming a strategic tool that can enhance a hotel's competitive advantage. This study explores how to develop the image and branding of a green hotel using the concepts of cognitive, affective and overall images. The study, based on a survey of 416 hotel users, also investigates how a green hotel image can affect behavioural intentions (i.e. intention to revisit, intention to offer positive recommendations to others and willingness to pay a premium). The findings confirm that cognitive image components (namely value and quality attributes) can exert a positive influence on a green hotel's affective and overall images. The affective image is also found to positively affect a green hotel's overall image. A green hotel's overall image, in turn, can contribute to more favourable behavioural intentions. Quality attributes were found to be more powerful than value attributes. The importance of the concept of selfish altruism and obtaining a feeling of wellbeing from a purchase were shown to be very strong. A range of theoretical and practical implications are discussed.

In Brief Objective: The aim of this study was to evaluate the safety of this trial with respect to morbidity and mortality. Summary Background Data: Laparoscopic-assisted distal gastrectomy (LADG) is rapidly gaining popularity. However, there is limited evidence regarding its oncologic safety. We therefore conducted a phase III multicenter, prospective, randomized study comparing LADG with open gastrectomy (ODG). Methods: Patient eligibility criteria were pathologically-proven adenocarcinoma, 20 to 80 years of age, preoperative stage I, no history of other cancer, chemotherapy, or radiotherapy. The primary end point was to determine whether there is a difference in overall survival between 2 groups. The morbidity and mortality were compared to evaluate the safety of this trial. The time was decided on the hypothesis that the morbidity of this trial was not significantly different from that of previous reports on open gastric cancer surgeries (17%–20%). This study is registered at ClinicalTrials.gov and carries the following ID number: NCT00452751. Results: A total of 342 patients were randomized (LADG, 179 patients; ODG, 161 patients) between January 1, 2006 and July 19, 2007. There were no significant differences between the 2 groups in age, gender, and comorbidities. The postoperative complication rates of the LADG and ODG groups were 10.5% (17/179) and 14.7% (24/163), respectively (P = 0.137). Reoperations were required in 3 cases each group. The postoperative mortality was 1.1% (2/179) and 0% (0/163) in the LADG and ODG groups (P = 0.497), respectively. Conclusion: There was no significance difference in the morbidity and mortality between the 2 groups. Therefore, we conclude that this trial is safe and is thus ongoing.

This study examined the relationships between three determinants of quality dimensions (predictors: food, service, and physical environment), price (moderator), and satisfaction and behavioral intention (criterion) in quick-casual restaurants. Despite the importance of foodservice quality, academics and managers know relatively little about how the combined effects of quality (food, service, and physical environment) elicit customer satisfaction which, in turn, affects behavioral intention. Hierarchical multiple regression analysis with interactions showed that quality of food, service, and physical environment were all significant determinants of customer satisfaction. In addition, perceived price acted as a moderator in the satisfaction formation process. Finally, the results indicated that customer satisfaction is indeed a significant predictor of behavioral intention. The findings may provide restaurateurs with a guideline for enhancing customer satisfaction and behavioral intention level.

The development of the flat morphology of leaf blades is dependent on the control of cell proliferation as well as cell expansion. Each process has a polarity with respect to the longitudinal and transverse axes of the leaf blade. However, only a few regulatory components of these processes have been identified to date. We have characterized two genes from Arabidopsis thaliana: ANGUSTIFOLIA3 (AN3), which encodes a homolog of the human transcription coactivator SYT, and GROWTH-REGULATING FACTOR5 (AtGRF5), which encodes a putative transcription factor. AN3 is identical to GRF-INTERACTING FACTOR1 (AtGIF1). The an3 and atgrf5 mutants exhibit narrow-leaf phenotypes due to decreases in cell number. Conversely, cell proliferation in leaf primordia is enhanced and leaves grow larger than normal when AN3 or AtGRF5 is overexpressed. Both genes are expressed in leaf primordia, and in the yeast two-hybrid assay, the gene products were found to interact with each other through their N-terminal domains. These results suggest that AN3 and AtGRF5 act together and are required for the development of appropriate leaf size and shape through the promotion and/or maintenance of cell proliferation activity in leaf primordia.

Numerous studies have employed the theory of planned behavior (TPB) to understand customers’ behaviors in various fields, but none has tested and extended the theory to explain customers’ decision formation to pay comparable regular-hotel prices for a green hotel. This is the first study designed to test and modify the TPB by including environmental concerns, perceived customer effectiveness and environmentally conscious behaviors, which are critical in explaining eco-friendly consumer behaviors. Salient belief items were identified using an elicitation method (focus group and open-ended survey). A survey obtained 389 respondents. Confirmatory factor analysis indicated that measurement items for all study variables had an adequate level of reliability and validity. The findings from the structural equation modeling showed that the proposed model had a satisfactory fit to the data and better predicted hotel customers’ intention than the original TPB. The results also indicated that all antecedent variables of intention significantly contributed to forming the intention to pay conventional-hotel prices for a green hotel. Respondents were happy to have minor inconveniences, e.g. reusing towels and using recycled products, and were keen to learn about the positive environmental attributes of green hotels. Benefit awareness was shown to be important in customer decision-making.

OBJECTIVE: To determine the safety of laparoscopy-assisted distal gastrectomy (LADG) compared with open distal gastrectomy (ODG) in patients with clinical stage I gastric cancer in Korea. BACKGROUND: There is still a lack of large-scale, multicenter randomized trials regarding the safety of LADG. METHODS: A large-scale, phase 3, multicenter, prospective randomized controlled trial was conducted. The primary end point was 5-year overall survival. Morbidity within 30 postoperative days and surgical mortality were compared to evaluate the safety of LADG as a secondary end point RESULTS: : A total of 1416 patients were randomly assigned to the LADG group (n = 705) or the ODG group (n = 711) between February 1, 2006, and August 31, 2010, and 1384 patients were analyzed for modified intention-to-treat analysis (ITT) and 1256 were eligible for per protocol (PP) analysis (644 and 612, respectively). In the PP analysis, 6 patients (0.9%) needed open conversion in the LADG group. The overall complication rate was significantly lower in the LADG group (LADG vs ODG; 13.0% vs 19.9%, P = 0.001). In detail, the wound complication rate of the LADG group was significantly lower than that of the ODG group (3.1% vs 7.7%, P < 0.001). The major intra-abdominal complication (7.6% vs 10.3%, P = 0.095) and mortality rates (0.6% vs 0.3%, P = 0.687) were similar between the 2 groups. Modified ITT analysis showed similar results with PP analysis. CONCLUSIONS: LADG for patients with clinical stage I gastric cancer is safe and has a benefit of lower occurrence of wound complication compared with conventional ODG.

Purpose The paper aims to examine the relationships among hedonic and utilitarian values, customer satisfaction and behavioral intentions in the fast‐casual restaurant industry. Design/methodology/approach The measures were developed based on a thorough review of the previous literature. Questionnaires were collected in classroom settings at a mid‐western university in the USA. Anderson and Gerbing's two‐step approach was employed to assess the measurement and structural models. Findings The findings indicate that hedonic and utilitarian values significantly influence customer satisfaction, and customer satisfaction has a significant influence on behavioral intentions. Utilitarian value shows a greater influence on both customer satisfaction and behavioral intention than does hedonic value. This study also reveals that customer satisfaction acts as a partial mediator in the link between hedonic/utilitarian value and behavioral intentions. Research limitations/implications Study findings will greatly help hospitality researchers and practitioners understand the roles of hedonic and utilitarian values in customer satisfaction and behavioral intentions in the fast‐casual restaurant industry. Originality/value The paper is the first to explore the relationships among hedonic and utilitarian values and their effect on customer satisfaction and behavioral intentions in the fast‐casual restaurant industry using Babin et al. 's two‐dimensional measure of consumer value.

This paper presents a multiobjective genetic algorithm approach to the design of a water distribution network. The objectives considered are minimization of the network cost and maximization of a reliability measure. In this study, a new reliability measure, called network resilience, is introduced. This measure mimics a designer’s desire of providing excess head above the minimum allowable head at the nodes and of designing reliable loops with practicable pipe diameters. The proposed method produces a set of Pareto-optimal solutions in the search space of cost and network resilience. Genetic algorithms are observed to be poor in handling constraints. To handle constraints in a better way, a constraint handling technique that does not require a penalty coefficient and is applicable to water distribution systems is presented. The present model is applied to two example problems, which are widely reported. Comparison of the present method with other methods revealed that the network resilience based approach gave better results.

Previous research has found that interactional justice and distributive justice are critical factors influencing customer satisfaction after a service recovery. In addition, previous service recovery research has found that satisfaction is an important determinant of key outcome variables such as trust, commitment, and negative word‐of‐mouth. The current study extends previous research by investigating the role of service failure severity within the existing framework of service recovery research. The results indicate that service failure severity has a significant influence on satisfaction, trust, commitment, and negative word‐of‐mouth. The results also provide partial support for a moderating influence of service failure severity. Implications and areas for future research are discussed.

Arsenic is a ubiquitous, naturally occurring metalloid that may be a significant risk factor for cancer after exposure to contaminated drinking water, cigarettes, foods, industry, occupational environment, and air. Among the various routes of arsenic exposure, drinking water is the largest source of arsenic poisoning worldwide. Arsenic exposure from ingested foods usually comes from food crops grown in arsenic-contaminated soil and/or irrigated with arsenic-contaminated water. According to a recent World Health Organization report, arsenic from contaminated water can be quickly and easily absorbed and depending on its metabolic form, may adversely affect human health. Recently, the US Food and Drug Administration regulations for metals found in cosmetics to protect consumers against contaminations deemed deleterious to health; some cosmetics were found to contain a variety of chemicals including heavy metals, which are sometimes used as preservatives. Moreover, developing countries tend to have a growing number of industrial factories that unfortunately, harm the environment, especially in cities where industrial and vehicle emissions, as well as household activities, cause serious air pollution. Air is also an important source of arsenic exposure in areas with industrial activity. The presence of arsenic in airborne particulate matter is considered a risk for certain diseases. Taken together, various potential pathways of arsenic exposure seem to affect humans adversely, and future efforts to reduce arsenic exposure caused by environmental factors should be made.

Beyond hemostasis and thrombosis, an increasing number of studies indicate that platelets play an integral role in intercellular communication, mediating inflammatory and immunomodulatory activities. Our knowledge about how platelets modulate inflammatory and immunity has greatly improved in recent years. In this review, we discuss recent advances in the pathways of platelet activation and potential application of platelet activation biomarkers to diagnosis and prediction of disease states.

IMPORTANCE: Laparoscopic distal gastrectomy is gaining popularity over open distal gastrectomy for gastric cancer because of better early postoperative outcomes. However, to our knowledge, no studies have proved whether laparoscopic distal gastrectomy is oncologically equivalent to open distal gastrectomy. OBJECTIVE: To examine whether the long-term survival among patients with stage I gastric cancer undergoing laparoscopic distal gastrectomy is noninferior to that among patients undergoing open distal gastrectomy. DESIGN: The Korean Laparoendoscopic Gastrointestinal Surgery Study (KLASS) group, which includes 15 surgeons from 13 institutes, conducted a phase 3, multicenter, open-label, noninferiority, prospective randomized clinical trial (KLASS-01) of patients with histologically proven, preoperative clinical stage I gastric adenocarcinoma from January 5, 2006, to August 23, 2010. Survival and recurrence status of the patients was determined in December 2016. INTERVENTIONS: Patients were randomly assigned (1:1) to laparoscopic distal gastrectomy (n = 705) or open distal gastrectomy (n = 711). Of these patients, 85 received a surgical approach opposite the one to which they were randomized (63 randomized to the open surgery group and 22 to the laparoscopic group). MAIN OUTCOMES AND MEASURES: Difference in 5-year overall survival between the laparoscopic and open distal gastrectomy groups. The noninferiority margin was prespecified as -5% (corresponding hazard ratio of 1.54), with an assumed survival of 90% after 5 years in the open surgery group. RESULTS: Among the 1416 patients (mean [SD] age, 57.3 [11.1] years; 940 [66.4%] male) included in the study, the 5-year overall survival rates were 94.2% in the laparoscopic group and 93.3% in the open surgery group (log-rank P = .64). Intention-to-treat analysis confirmed the noninferiority of the laparoscopic approach compared with the open approach (difference, 0.9 percentage points; 1-sided 97.5% CI, -1.6 to infinity). The 5-year cancer-specific survival rates were similar between the 2 groups (97.1% in the laparoscopic group and 97.2% in the open surgery group, log-rank P = .91; difference, -0.03 percentage points; 1-sided 97.5% CI, -1.8 to infinity). Per-protocol analysis results were consistent with the intention-to-treat results for overall and cancer-specific survival rates. CONCLUSIONS AND RELEVANCE: The KLASS-01 trial revealed similar overall and cancer-specific survival rates between patients receiving laparoscopic and open distal gastrectomy. Laparoscopic distal gastrectomy is an oncologically safe alternative to open surgery for stage I gastric cancer. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00452751.

Free radicals, characterized by the presence of unpaired electrons, are highly reactive species that play a significant role in human health. These molecules can be generated through various endogenous processes, such as mitochondrial respiration and immune cell activation, as well as exogenous sources, including radiation, pollution, and smoking. While free radicals are essential for certain physiological processes, such as cell signaling and immune defense, their overproduction can disrupt the delicate balance between oxidants and antioxidants, leading to oxidative stress. Oxidative stress results in the damage of critical biomolecules like DNA, proteins, and lipids, contributing to the pathogenesis of various diseases. Chronic conditions such as cancer, cardiovascular diseases, neurodegenerative disorders, and inflammatory diseases have been strongly associated with the harmful effects of free radicals. This review provides a comprehensive overview of the characteristics and types of free radicals, their mechanisms of formation, and biological impacts. Additionally, we explore natural compounds and extracts studied for their antioxidant properties, offering potential therapeutic avenues for managing free radical-induced damage. Future research directions are also discussed to advance our understanding and treatment of free radical-associated diseases.
