In this study and design, I explore the visual communication design process related to wayfinding in Wonkwang University Hospital in Iksan City. The purpose for designing an integrated is to graphically communicate the complex information. I have designed a graphic information system combining graphic elements such as typography, color, image and text layout, and graphic image to present interpretive and communicative processes. As a result of designing, the wayfinding is s term used to describe the program of applying environmental graphics and or architectural sign systems. In other words, wayfinding is the art of helping people find their way by utilizing visual communications such as signs, directories, landmarks, edges, paths and so on. Wayfinding can also be explained as the ability to know where one is in space and how to find one's way through space. Wayfinding design then becomes a systematic arrangement of the variables that allows patients and visitors to successfully find their desired destinations, especially in a hospital.

In this letter, we propose a one-way ranging algorithm that is based on wireless synchronization with measured timestamps and clock frequency offsets. In our proposed algorithm, an active mobile node initiates a ranging procedure by transmitting a ranging frame, and the anchor nodes report their timestamps for the received ranging frame to a reference anchor node. The synchronization of a pair of nodes is provided with instantaneous time information, and the corresponding difference of distances can be calculated.

This study was conducted to determine the relationship between nursing students' empathy, communication skills, and major immersion, and to identify factors that affect major immersion. The subjects of the study were 247 nursing students from one university in the G province, and data collection was conducted from November 20 to December 1, 2023. Data analysis was performed using SPSS 22.0 using descriptive statistics, t-test, one-way ANOVA, Scheffe test, Pearson correlation coefficient, and multiple regression analysis. The subject's empathy ability was 3.49 points, communication ability was 3.64 points, and major immersion was 3.61 points. Major immersion has a positive correlation with empathy and communication ability, and the factors affecting major immersion are major satisfaction and communication ability, with an explanatory power of 42.9%. To improve nursing students' immersion in their major, it is necessary to set the direction of learning activities and develop and apply various extracurricular programs.

On Korean websites, people often use several Korean vowels or consonants solely, which is the way to express emotion. This way of expression has scarcely been examined seriously, though it is one of the most popular online slangs. This is an exploratory study that reveals how and how much these expressions are used on social media. Data crawling technique was used as a way to examine the usage of vowels and consonants in ordinary situations. 6 'Facebook pages' popular among Korean users are selected, and about 2.5 million comments are collected from posts in those pages. 10 expressions, including 'ㅋ(K)', 'ㅎ(H)', 'ㅜ(U)', are counted and analyzed from the collected texts of comments. As a result, several patterns of using vowels and consonants are found. Especially, 'ㅋ(K)' is used much more frequently than other vowels or consonants, and used more continually. It is also found that the patterns of using vowels or consonants in writing comments changes as the mood of posts or the characteristics of Facebook pages.

In the early 1990s, IETF(Internet Engineering TaskForce) had started the discussion on new address protocol that can modify and supplement various drawbacks of existing IPv4 address protocol with the introduction of CIDR(Classless Inter-Domain Routing) which is a temporary solution for IPv4 address depletion, NAT, private IP address. While various standards related to new address protocol has been proposed, the SIPP(Simple Internet Protocol Plus) was adopted among them because it is regarded as the most promising solution. And this protocol has been developed into current IPv6. The new concepts are introduced with modifying a lot of deficiencies in the exisitng IPv4 such as real-time data processing, performance on QoS, security and the efficiency of routing. Since many security threats in IPv6 environment still exist, the necessity of stable data communication environment has been brought up continuously. This paper deveopled one-way communication algorithm in IPv6 based on the high possibility of protecting the system from uncertain and potential risk factors if the data is transmitted in one way. After the analysis of existing IPv6 and ICMPv6, this paper suggests one-way communication algorithm as a solution for existing IPv6 and ICMPv6 environment.

This study examined the relationship between marital cohesion adaptability and marital communication and especially tested the linear versus curvilinear hypothese with Circumplex Model. The subjects were 142 couples living in Pusan./ The data were analyzed using frequency one-way ANOVA and Pearson's correlation coefficient The major finding of this study were as follows: The relationship between the dimensions of cohesion adaptability and communica-tion was linear than curvilinear. High cohesion and high adaptability spouses were more effective communication than low cohesion and low adaptability.

In this paper, we maximize the lifetime of a multi-hop path through a cooperative wireless energy sharing scheme between constituent nodes in a wireless multi-hop communication. Considering a bidirectional multi-hop communication environment, we present an optimization problem to maximize path lifetime by adjusting the amount of energy each node needs to share with its neighboring nodes. On the basis of solidarity property, i.e., the lifetime of the multi-hop path is maximized when the lifetimes of all nodes are the same, we convert the considered optimization problem into a linear programming problem and solve it easily. Simulation result shows that the proposed two-way wireless energy sharing method maximizes the path lifetime of multi-hop communications and approximately doubles the path lifetime compared with the one-way energy sharing method.

Purpose: The objective of this study was to investigate the influence of hospital nurses' self-leadership, communication skill, and self-esteem on the quality of nursing service. Methods: The participants, 230 nurses working at a general hospital in Seoul, completed a cross-sectional descriptive questionnaire survey between January 17 and 28, 2014. The collected data were analyzed using the SPSS 19.0 program for descriptive statistics, t-test, one way & two way ANOVA, correlation, and multiple regression analysis. Results: Nurses' self-esteem and communication skill had significant main effects on self-leadership and the quality of nursing service, but the interaction effect of the two independent variables was not significant. Variables that significantly influenced the quality of nursing service were self-leadership, communication skill, self-esteem, and career longevity. The explanatory power of these variables for the quality of nursing service was 54.4%. Conclusion: Findings indicate a need for education programs for nurses which are designed to promote communication skill and enhance self-esteem and self-leadership skills which will in turn enhance the quality of nursing service.

One of the reasons that debugging distributed programs is much more difficult than sequential programs is the communication among processes. Even though there are many debuggers constructed on distributed system environment, no available debugger provides an efficient way to debug communication events.. In this paper, we show the way to debug RPC communication, which is regarded as one of the most popular communication protocol in distributed system development. This paper presents the implementation of the RPC event trace function based on the RPC event model, which is proposed to accommodate communication events into debugging objects. Analyzing conventional RPC protocols, we formalized library function calls as corresponding actions to sending and receiving of messages. B recognizing the locations of library calls the debugger can detect all occurrences of communication events, This RPC event trace function is implemented on the on-line distributed debugger UniVIEW system.

This study tried to identify hospital internal marketing, organizational communication, and the degree of organizational performance targeted at nurses working in university hospitals, and apprehend factors affecting organizational performance. A structured questionnaire, where 239 nurses answered, was used to figure out general features, hospital internal marketing, organizational communication, and organizational performance. Descriptive statistics, Indepented t-test, one-way ANOVA, correlation, and multiple regression analyses were used to analyze the data. The analyzing tool was IBM SPSS 21.0 program. The result of this study was as follows: hospital internal marketing 3.13±0.58 points, organizational communication 3.23±0.48 points, and organizational performance 3.34±0.51 points. Organizational performance showed a positive correlation with hospital internal marketing and organizational communication, and those two explained 61.0% of organizational performance. Therefore, hospital internal marketing strategy - encouraging nurses in individual aspect - and integrated strategy - establishing various communication channels in organizational aspect - are required to increase the organizational performance of nurses.
