Zigbee, which was a representative standard technology for dealing low energy and mesh networks in large deployment area such as smart home, smart building, and massive sensor networks, has been developed and deployed for increasing communication area by using Ad hoc method. It has been originally developed based on IEEE 802.15.4 standard so every node needs 48bit unique address defined by IEEE. However, it is absolutely inefficient to assign an unique address to every communication node where it would be deployed through large-scale network area, e.g., smart lighting and massive sensor networks, because there could be variously multiple companies to deploy network infrastructure and they could have different policy to assign node ID. To prevent the problem, this paper proposes a method of dynamic PANID assignment in overall Personal Coordinators, and also proposes a method for addressing PANID conflict problem which could be derived from dynamic PANID assignment.

This paper is to analyse conflict between the US and China over the South China Sea and Korea's responses. To this end the paper is composed of 6 chapters titled instruction; the current status of South China Sea sovereignty disputes; changes in US and Chinese maritime security strategies and the strategic values of the South China Sea; key issues and future prospects for US-China conflicts in the South China Sea; South Korea's security and diplomatic responses; and conclusion. The recent East Asian maritime security issue has evolved into a global issue of supremacy between the US and China, beyond conflicts over territorial disputes and demarcation among the countries in the region. China is pursuing offensive ocean policy to expand economic growth. The core of the maritime order that the United States intends to pursue is the freedom of navigation in the oceans and the maintenance of maritime access. China is making artificial islands in the South China Sea, claiming the sovereignty of these islands, building strategic bases in East Asia, and securing routes. The United States has developed several "Freedom of Navigation Operations" to neutralize the declaration of the territorial sea surrounding Chinese artificial islands. We can not be free from marine conflicts in the South China Sea and the East China Sea. Regarding the South China Sea dispute, it is expected that the strategic competition and conflict between the two countries will intensify due to China's failure to make concessions of core interests and adherence to the US compliance with international norms. In the midst of conflict over the South China Sea, we need a harmonious balance between our alliance security and economic diplomacy. We must continue our efforts to strengthen the ROK-US alliance but not to make China an enemy. Considering the significant impacts of the oceans on the survival and prosperity of the nation, we must continue to develop our interest in the oceans, appropriate investments and tactical strategies.

Recent marine territorial disputes in the East China Sea and the South China Sea have come to us as a great threat. China, which has recently established the China Coast Guard and has rapidly developed maritime security forces, is trying to overcome the various conflict countries with its power. Japan is also strengthening intensively its maritime security forces. Since Korea, China, and Japan are geographically neighboring and sharing maritime space in Northeast Asia, there is no conflict between maritime jurisdiction and territorial rights among the countries. The struggle for initiative in the ocean is fierce among the three coastal nations in Northeast Asia. therefore, Korea needs more thorough preparation and response to protect the marine sovereignty. As the superpowers of China and Japan are confronted and the United States is involved in the balance of power in strategic purposes, the East Asian sea area is a place where tension and conflict environment exist. China's illegal fishing boats are constantly invading our waters, and they even threaten the lives of our police officers. The issue of delimiting maritime boundaries between Korea and China has yet to be solved, and is underway in both countries, and there is a possibility that the exploration activities of the continental shelf resources may collide as the agreement on the continental shelf will expire between Korea and Japan. On the other hand, conflicts in the maritime jurisdictions of the three countries in Korea, China and Japan are leading to the enhancement of maritime security forces to secure deterrence rather than military confrontation. In the situation where the unresolved sovereignty and jurisdiction conflicts of Korea, China and Japan continue, and the competition for the strengthening of the maritime powers of China and Japan becomes fierce, there is a urgent need for stabilization and enhancement of the maritime forces in our country. It is necessary to establish a new long-term strategy for enhancing the maritime security force and to carry out it. It is expected that the Korean Coast Guard, which once said that it was a model for the establishment of China's Coast Guard as a powerful force for the enforcement of the maritime law, firmly establishes itself as a key force to protect our oceans with the Navy and keeps our maritime sovereignty firmly.

This study was attempted to provide nurse students with basic materials to improve their clinical practices, and to investigate changes in their views on Nursing Professionalism, Job satisfaction, and role conflicts. After experiencing clinical practices, their nursing professionalism(t=-2.184, p=.031) and job satisfaction (t=-2.068, p>.001) increased but role conflict (t=-3.729, p>.001) increased as well. They were satisfied with their jobs, building up nursing professionalism through clinical practices. However, they had also acquired time on thinking about their future jobs more deeply than before practices and realizing their roles in real sense. In particular, they felt stress in some of subcategories, personal inner conflicts (t=-3.729, p>.001), role obscurity (t=-5.720, p>.001) so it is necessary to review standards on their job and task in nurse education and clinical practices.

This study tries to figure out the communication types between a mother-in-law and a foreign daughter-in-law through their 'confrontational conversation.' For this, three episodes of 'Multicultural Mother-in-law and Daughter-in-law Biography' aired by EBS (Education Broadcasting System) were monitored. The dialogues between the mother-in-law and the foreign daughter-in-law were written down and analyzed. According to the result, there were 'dysfunctional communication' styles during their conversation. Theses styles deepened their conflict. Thus, to abate the conflict between the mother-in-law and the foreign daughter-in-law, this study suggested that it was necessary to develop the convergence counseling program and the family therapy for their functional communication.

This study aimed to identify the effects of infection control nurses' role conflict and job satisfaction on their turnover intention. Data were collected from 122 infection control nurses in January 2019. Data were analyzed by descriptive statistics, independent t-test, One-way ANOVA, Scheffé test, Pearson's correlation, and Multiple regression in SPSS/WIN 23.0. Participants' turnover intention was positively correlated with their role conflict (r=.46, p<.001), and negatively with job satisfaction r=-.21, p=.021). The role conflict (β=.43, p=.003), level of education (β=.29, p=.040), and job satisfaction (β=-.20, p=.013) was a significant predictor of the turnover intention (R²=.27). Therefore, it will have to be accompanied by institutional efforts to minimize role conflicts and improve job satisfaction. In addition, differentiated turnover strategies based on academic level should be developed.

Purpose: The purpose of the study >was to examine the prevalence of work-related musculoskeletal disorders(WMSDs) and to identify the relationship between work-related psychosocial and acculturative factors and WMSDs among Korean-Chinese workers living in Korea. Methods: A cross-sectional survey was conducted with 195 Korean-Chinese workers who have worked full-time for the past 6 months. A structured questionnaire, including measures for musculoskeletal symptoms, physical demand, work-related psychosocial(job demand, job control, interpersonal conflict), acculturative (acculturation strategy and acculturative stress), and personal factors, was used. Descriptive statistics and logistic regression analysis were conducted using the SPSS WIN 17.0. Results: The prevalence of WMSDs was 64.1%. In comparison to Korean workers, job demand of this group was lower while both interpersonal conflict and lack of job control were higher among them. Integration was the most commonly used acculturation strategy and mean scores of acculturative stress were below the median. Acculturative stress was positively correlated with integration and assimilation while negatively correlated with separation and marginalization. Interpersonal conflict and integration appeared to be related to WMSDs among male and female Korean-Chinese workers, respectively. Conclusion: The WMSD interventions need to be planned in consideration of different influences of work-related psychosocial and acculturative factors on WMSDs by gender.

The paper will investigate the chances of progress in the peace process in Middle East. Robert Hazo's 1993 article mainly argued the Palestinians and Syrian problems. He saw that these two problems are one of the key issue that current Middle East problem which involves Israel. The key tenants of his argument will be dissected to assess whether this view holds true in the light of developments in the Middle East in the intervening years. The Arab-Israeli struggle remains one of the most intractable in history. In 1993 Robert Hazo concluded that 'the conflict is a terminal struggle'. This paper investigates his analysis in light of progress or lack of in the intervening period and against the contemporary strategic environment. It uses information presented in academic, government, newspaper and world wide web articles to conclude that Hazo's assessment remains valid. While the various talks since 1993 combined with the potential benefits the United States, Israel and Syria could gain from a settlement proffer hope, the issue of 'right of return, borders and Jerusalem are unlikely to be bridged in the near future.

Purpose: This study examined the effect of hospitals' family-friendly management on married female nurses' retention intention. The focus was the mediating effects of the work-family interface (work-family conflict, work-family enrichment and work-family balance). Methods: This study was a cross-sectional study. The participants were 307 nurses working at five public and five private hospitals with more than 200 beds in Seoul. Data were collected using structured questionnaires from September 10 to September 17, 2018 and analyzed with SPSS 24.0. Data were analyzed using an independent t-test, a one-way ANOVA, Pearson's correlation coefficients, and multiple regression following the Baron and Kenny method and Sobel test for mediation. Results: There were significant correlations among family-friendly management, the work-family interface, and retention intention. Work-family conflict showed a partial mediating effect on the relationship between family-friendly management and retention intention. Work-family enrichment showed a partial mediating effect on the relationship between family-friendly management and retention intention. Work-family balance showed a partial mediating effect on the relationship between family-friendly management and retention intention. Conclusion: These findings indicate that both hospitals' family-friendly management and nurses' work-family interface are important factors associated with nurses' retention intention. Therefore, hospitals should actively implement family-friendly management for nurses and establish strategies to enhance nurses' work-family interface for effective human resource management.

The purpose of this study is to examine pathways of factors that influence job satisfaction for full-time and part-time married female employees with children of 18 or under and to compare path coefficients for two groups. Simultaneously analyzing multiple populations, we found that the path model was appropriate for both groups with significant differences in path coefficients. Income, workplace size, husband's support for wife's work, and work-to-family conflict had direct effects on job satisfaction for both groups whereas health had a direct effect only among full-time workers. Family-to-work conflict had an indirect effect for both types of workers, while health had an indirect effect among full-time employees only, and income and having children under school age among part-time employees only. The results indicate that differentiated approaches to increase job satisfaction for full- and part-time employees are needed.
