The purpose of this study is to extract the key words from the list of research subjects related to 'hotel workers' published in recent 10 years(2009~2018) by using the language network analysis method and to confirm the relation between the key words. In this paper, we propose a semantic network analysis that can overcome limitations of longitudinal study, analyze the recent research trends, and widely use as a research model. The results of this study are as follows ; First, in analyzing major key words in the title of 'Hotel Employer' in recent 10 years, the major keyword of job satisfaction(40), special grade(26), organizational commitment(20), emotional labor(19), service(12), restaurant(10), and turnover intention(9). Second, we analyzed the relation of language network among major key words extracted from the study title of 'hotel workers'. Such a research process is expected to grasp the trends of research related to 'hotel workers' and give implications for the future direction of related research.

The earthquake test Procedures specified in three international codes were reviewed and compared for the network equipments. As technical level on the electronics and networking is growing in Korea, many related equipments are required to export to abroad. The network equipments are now essential tools for communication among individuals as well as societies, especially at the hazard situation such as earthquake strike. The Korean network companies are trying to improve the earthquake resistance performance for their products to expand domestic and international markets. In this paper it is reviewed that most codes related on the earthquake tests can be performed with the facilities provided in Korea for the network equipments. However new facility is required to prepare for more performance and higher regulating codes expected.

This research aims to analyze the trend of subhealth and meebyung(未病) research as a method of network analysis from 2007 to 2011 in China. A total of 3,933 papers were involved in analysis from 5,465 searched papers, which title have '未病', '亞健康' in CNKI (China National Knowledge Infrastructure). It is carried out that counts annual paper number, authors' publicized papers, and journals paper number related to subhealth. Network analysis was performed to reveal collaboration research trend and relations between Authors, Affiliations, and Regions. As a result, Number of related studies have increased for the last 5 years. East and south regions of China, which include Beijing, Guangxi, and Zhejiang have participated most in their studies, and also as collaborated researches. As affiliations, Researches done by College of Traditional Chinese medicine and their hospital's collaborations are most counted. Because of distance limit, many colleges or institutes seem to make contacts with nearby affiliations. This study is the first attempt to perform network analysis on subhealth research trend in CNKI. This study would contribute to related studies in case of network analysis method.

네트워크 공격 대응에 관한 보안기술의 기존 연구들은 하드웨어적 네트워크 보안 기술을 이용하여 네트워크의 보안성을 높이는 방법이나 바이러스 방역 백신과 바이러스 방역 시스템이 주로 제안 설계되어왔다. 많은 사용자는 라우터의 보안 기능을 충분히 활용하지 못하고 있어 이러한 문제점을 극복하기 위해 네트워크 보안 수준에 따라 분리함으로써 계층화된 보안 관리를 통하여 외부에서의 공격을 차단할 수 있음을 계층별 실험을 통해 분류하였다. 연구의 범위는 Edge 라우터의 보안기술 동향을 살펴봄으로 Edge 라우터 기반의 네트워크 공격에 관한 위협으로부터 보호하는 방법과 구현 사례를 제시한다.

This study delved into the effects of labor union members' social media utilization for the formation of labor union social capital. Specifically, this study aimed to identify the effects of labor union-related social media use and participation on the labor union's social capital formation through quantitative and qualitative research. It set up trust, network, and participation as social capital components and as dependent variables. Network, in particular, was divided into bonding and bridging aspect. There is the correlation between labor union-related social media use and the formation of labor union social capital. As participation in the group type social media operated by a labor union becomes more active, evaluation on labor union social capital throughout trust, network, and participation is higher. Especially, the correlation between bonding network and bridging network was high. This proves that a labor union's bond enhancement does not result in the labor union's selfishness, but it can build a cooperative system with an external network.

본 연구에서는 인구고령화에 따라 관심이 높아진 고령친화산업의 현황과 특성을 살펴보기 위해, 고령친화용품산업체를 대상으로 품목별 분류와 입지 특성, 기업 유형 등을 분석하였다. 특허수를 이용한 혁신수행력과 고령친화산업 관련 네트워크참여도를 기준으로 $3\times3$행렬의 9가지로 업체들을 분류하였고, 이에 덧붙어 다른 기관과의 협력, 제조 및 유통 여부 등에 따라 최종적으로 5가지 유형으로 정리하였다. 5가지 유형은 혁신수행력이 높고 네트워크참여도도 높은 유형(HPHC), 중 저기술 제조업체로 네트워크 리더의 역할을 하는 유형(NL-LTM), 유통업체로 네트워크 리더의 역할을 하는 유형(NL-D), 혁신수행력은 높지만 네트워크참여도가 낮은 유형(HP-NO), 혁신수행력이 낮고 네트워크참여도도 낮은 유형(LPI)이다. 이러한 분석결과를 바탕으로 고령친화산업을 발전시키기 위한 산업 및 공간 정책에의 시사점을 제시하였다.

This study investigates how adolescents' smartphone attachment, social anxiety, and offline and smartphone network sizes are related to their friendship in regards to maintaining either a strong or weak bond. Based on an online survey involving 402 adolescent smartphone users in South Korea, this study found that smartphone attachment was positively related to a strong ties friendship maintenance and negatively related to weak ties friendships. Similarly, social anxiety was found to be negatively associated with friendship maintenance for both strong and weak - tie relationships. More importantly, this study revealed that the types and size of social networks moderated the relationships among adolescents with smartphone attachment, social anxiety, and friendship maintenance through smartphones.

Text mining techniques provide valuable insights into research information across various fields. In this study, text mining was used to identify research trends in wood science from 2012 to 2022, with a focus on representative journals published in Korea and Japan. Abstracts from Journal of the Korean Wood Science and Technology (JKWST, 785 articles) and Journal of Wood Science (JWS, 812 articles) obtained from the SCOPUS database were analyzed in terms of the word frequency (specifically, term frequency-inverse document frequency) and co-occurrence network analysis. Both journals showed a significant occurrence of words related to the physical and mechanical properties of wood. Furthermore, words related to wood species native to each country and their respective timber industries frequently appeared in both journals. CLT was a common keyword in engineering wood materials in Korea and Japan. In addition, the keywords "MDF," "MUF," and "GFRP" were ranked in the top 50 in Korea. Research on wood anatomy was inferred to be more active in Japan than in Korea. Co-occurrence network analysis showed that words related to the physical and structural characteristics of wood were organically related to wood materials.

The purpose of this paper is to find the most vital arc in the minimum cost flow problem. The most vital arc is the arc whose removal results in the greatest influence in the costs or the amount of demands in a given minimum cost flow network. This problem can be well applied to the conflict situations such as military logistics network or communications network. In this situation, network user wants to know which arcs are the most vital to him so that he can reinforce these arcs against attack, while interdictor wants to destroy these arcs which increase the distance of the shortest path most through the network. When one of arcs is removed from the network of the minimum cost flow problem, two kinds of situations can be occurred ; breaking feasibility and increasing cost. In case of breaking feasibility, the rank of arcs are determined using the amount of modified flow in a related network which is made of modifying the optimal alternative of the minimum cost flow problem. The rank of arcs with the increased costs are determined by using a method which finds the directed cycle with the minimum cost in a related network.
