We propose a new channel reservation protocol which can reduce message delay by using a counter for detection of d source conflict in a WDM single-hop network with non-equivalent propagation delay. A source convict occurs when a source node has the right to transmit more than or equal to two messages simultaneously, which are transmitted using different wavelengths. In such a case, the source node has to newly obtain the right to transmit the message. In the proposed protocol, by using a source conflict counter a source node can detect a source conflict before a wave-length assignment is performed. Therefore, the source node can start a procedure to newly obtain the right to transmit the message which cannot be transmitted due to a source conflict. We analyse the throughput performance by taking the effect of a source conflict into account, and show that the approximate analysis and the computer simulated results are close. Also, from computer simulated results, we show that our proposed protocol can reduce mean message delay dramatically without degrading throughput performance as the offered load becomes large.

Users' norms, expectations and recreation motives are major influential factors on perceived conflict in recreation settings. This study was conducted to examine how information affects users' norms and expectations, and subsequently, the extent of perceived conflict. Data was collected at the Second Campground in Chirisan National Park in 1994. Of two hundred eighty on-site survey questionnaires distributed, 253(90.4%) were used for analysis. According to the result of the study, information changed users' normative standards in accord with the content of information and increased the extent of norm convergence. However, it did not change users' expectations and didn't reduce the degree of perceived canflict. The possible reasons were discussed. Some directions for more effective use of information to reduce perceived conflict were also suggested.

The ultimate aim of this work is to explore the antecedents that affect the loneliness felt by users who actively communicate through smartphones apps. To do this, three characteristics including individual, relational, and communication characteristics that can affect loneliness and the effects of these characteristics on loneliness are empirically analyzed. The research results are as follows. First, we found that conflict resolution ability had a significant effect on interpersonal conflict and loneliness. Second, social stress was found to have a significant effect on interpersonal conflict, communication fatigue, and loneliness. Third, lack of communication was found to have a significant effect on conflict resolution ability and loneliness. Finally, we found that communication fatigue had a significant effect on loneliness. These results are interpreted that in order to reduce the loneliness, it is necessary to continuously improve the ability to wisely resolve conflicts that may arise in the relationship between oneself and others. In addition, it is necessary to reduce the fear or burden of building relationships with others.

The attribute grammar is a grammar for static semantic rules to overcome the difficulties of type checking. But this attribute grammar is difficult to write and understand by its additional rules. A grammar would be preferable if it has simple and small size of an attribute grammar. This paper shows how to decrease the size of an attribute grammar for an expression using LH method. This approach considers the types of an expression. That is, the construction of a semantic relation between the types of the expression can make it possible that an attribute grammar be written with its simpler and smaller size.

Visible Light Communication (VLC) using Light Emitting Diodes (LEDs) within the existing lighting infrastructure can reduce the implementation cost and may gain higher throughput than radio frequency (RF) or Infrared (IR) based wireless systems. Current indoor VLC systems may suffer from poor downlink resource allocation problems and small system throughput. To address these two issues, we propose an algorithm called a conflict graph scheduling (CGS) algorithm, including a conflict graph and a scheme that is based on the conflict graph. The conflict graph can ensure that users are able to transmit data without interference. The scheme considers the user fairness and system throughput, so that they both can get optimum values. Simulation results show that the proposed algorithm can guarantee significant improvement of system throughput under the premise of fairness.

The rapid adoption of smartphones and tablets among employees has recently forced organizations to proactively embrace bring your own device (BYOD). The situation of COVID-19 makes the concept of BYOD even paramount. Allowing employees to bring their own mobile devices to the workplace has helped companies realize productivity gains and cost benefits. However, BYOD has also blurred the boundaries between work and personal life, thereby creating a stressful environment for employees (Doargajudbur and Hosanoo, 2023). This study explores the relationships between several BYOD attributes and investigates the effects of these attributes on work-to-life conflict. It contributes by introducing workplace connectivity after hours as a new dimension of BYOD attribute to influence work-to-life conflict. Based on boundary theory, a theoretical model is developed and tested with an online survey. The results reveal that flexibility and workplace connectivity after hours positively influence productivity, and flexibility helps to relieve instead of increase work overload. Meanwhile, a higher level of flexibility and productivity can help reduce work-to-life conflict, and a higher level of work overload induces a higher level of work-to-life conflict.

Purpose: This study aimed to identify the influence of marital conflict and family function on fatigue in mothers of young children hospitalized for acute diseases. Method: Via a cross-sectional design utilizing structured questionnaires, fatigue, marital conflict, and family function data of 120 South Korea mothers of such hospitalized children were collected and surveyed. The data were analyzed via t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS Statistics. Results: Fatigue level was found to positively correlate with marital conflict and negatively correlate with family function. Overall, marital conflict, was significant predictor of maternal fatigue, explaining 33.0% of the model, with physical fatigue level being the highest type of fatigue. Conclusion: Therefore, a family-centered care program for families of hospitalized children needs to be developed. Comprehensive family nursing interventions that reduce fatigue levels and help reinforce marital relationships in families of hospitalized children are essential.

Objectives: This study was conducted to confirm the relationship between role conflict, positive psychological capital, and the psychological well-being of dental hygienists and to provide data for improving professionalism by increasing the psychological well-being of dental hygienists. Methods: From May 21 to June 22, 2023, 190 data were collected through an online community of dental hygienists. The collected data were analyzed IBM SPSS program ver. 23.0 and AMOS ver. 26.0. Statistical analysis methods, convergent validity test, structural equation model analysis, and model fit were performed using independent sample t-test, one-way ANOVA, confirmatory factor analysis, structural model fit test, and path analysis. Results: The lower the role conflict of dental hygienists and the higher the positive psychological capital, the higher the psychological well-being. The lower the role conflict, the higher the positive psychological capital. However, there was no mediating effect between positive psychological capital and role conflict, as it was not statistically significant. Analysis of the total effect of role conflict and positive psychological capital on psychological well-being revealed that positive psychological capital had a greater influence on psychological well-being than role conflict. Conclusions: Psychological well-being was related to positive psychological capital and role conflict. Future efforts are needed to improve positive psychological capital and psychological well-being of dental hygienists and reduce role conflict.

The state adopts the policies based on the goals pursued by the state and provides a basic policy for administrative activities related to early childhood education. Therefore, early childhood education policy should be established organically in consultant with the social consent in advance. In most countries will bear the costs of child care and early childhood education can reduce the financial burden of parents and early childhood education consumers are able to understand the will of the government to support the child care services, which they need in a variety of way. The conflict is deepening - among policy officials, front-line institutions participating in policy implementation, and parents - surrounding the infant and early childhood education. And the conflict has caused the difference between this policy and claims that cannot find hardly a solution. In this study, we argue how the policy differences between groups involved in the policy to analyze the influence, to find the policy conflict resolution strategies.

Purposes: The purpose of this study was to investigate the relationship between male nurse's gender stereotype, role conflict and organizational commitment. Methodology: Data were collected from 169 male hospital nurses from August, 2016 until September. The Male nurse's gender stereotype, role conflict and organizational commitment were measured using a structured questionnaire. Collected data were analyzed using SPSS/win 23.0 for windows. Descriptive statistics, t-test, ANOVA and Pearson's correlation were used. Findings: There were statistically significant differences in the gender stereotype by general characteristics such as age and military duty. There were statistically significant differences in the role conflict by general characteristics such as education level and position. There were statistically significant differences in the organizational commitment by general characteristics such as the hospital's location and hospital type. Gender stereotype and role conflict had no significant correlation (r=-0.050, p=.516). A statistically significant positive correlation was detected between male nurse's gender stereotype and 'continuance commitment' (r=0.272, p<.001). A statistically significant positive correlation was detected between male nurse's role conflict and 'continuance commitment' (r=0.178, p=.021). Practical implications: The result of this study indicate that to reduce role conflict of workplace environment and induce the affective commitment of male nurses within a female-centered nursing organization should be sought.
