This study explored the meaning and essential structure of the life of 12 older wage earners who are 65 years old or older residing in Seoul. For the in-depth analysis of the qualitative interviews, Giorgi(2012)'s phenomenological research method was used. Results presented a total of 349 meaning units, 35 core meanings, 16 emerging themes, and 6 essential themes. These essential themes consisted of a life tolerating contempt and prejudice, the hungry belly in the later years, a yoke of the subordinate, an unclimbable vertical wall, reviving the hours of youth through working, and labor pride. These six essential themes led to the essential structure of'small happiness that is felt at times out of the weary working life in later years. The research participants felt worn out by the social discrimination and unfair working conditions against older wage earners, but they felt relieved that they were able to work in old age and had a sense of self-esteem through their work. Working was the important tools for older wage earners to experience happiness in later years because it not only relieved their financial burden but also brought a sense of self-esteem and labor pride. Based on the results, we suggested as following: 1) with respect to social discrimination and unfair working conditions against older workers, the whole society should discuss it as the protection of human rights and take legal actions; 2) various service jobs need to be created so that older workers can contribute to the society by utilizing their experiences; and 3) educational programs of computer or internet use must be expanded through which older wage earners can improve their job skills.

Purpose: The purpose of this study was to identify the knowledge, attitude and preventive behaviors of tuberculosis in male high school students and to identify the factors influencing preventive behaviors and to provide basic data for the development of prevention programs for tuberculosis of male high school students. Methods: This study was conducted from May 1, 2018 to May 30, 2018, and six high school students in S city and Y city of Jeonnam were selected. 465 male high school students in the first grade were selected. Collected data were analyzed using t-test, ANOVA, pearsons's correlation and Multiple regression analysis by SPSS/WIN 21.0 program Results: As a result, the knowledge score was 11.92, the attitude score was 28.32 and the prevention behavior score was 30.07. All of these correlations were statistically correlated. In addition, factors influencing preventive actions against tuberculosis were attitude toward tuberculosis, exercise, health status, and sleep time Conclusion: Based on the above results, it is thought that to improve the preventive behavior of tuberculosis in male high school students, it is necessary to develop a practice-oriented program for forming healthy lifestyle as well as to change the attitude toward tuberculosis positively.

The purpose of this study was to explain, using Jacques Lacan's theory of desire, how Ellen Olenska functions as the object petit a in her relationship with Newland Archer and to connect the impossibility of Newland and Ellen's love with the impossibility of desire, in Edith Wharton's The Age of Innocence. In New York society in the 1870s, the unpleasant truth was avoided, personal opinions were excluded, no room for imagination existed, and other-ness was expelled. In that society, Newland realized that true love and true emotions were lacking in his life. For Newland, Ellen was the gap in New York society and the object that could fill that gap. Ellen functioned as the object petit a. But the romance between Newland and Ellen was forbidden in New York society, where everything was dominated by strict social codes, and especially because Newland was engaged to Ellen's cousin, May Welland. Ellen became inaccessible to Newland and this set Newland's desire for Ellen in motion. He idealized Ellen as the objet petit a, based on the fantasy that she would fill the void in his life. However, at every critical moment, Newland delayed unification with Ellen by resorting to social codes. His actions betrayed that the goal of his desire was not the fulfillment, but the reproduction of desire, with its circular movement. His decision not to see Ellen in Paris again at the end of the novel can be interpreted as Newland's effort to maintain Ellen as the inaccessible object, objet petit a, forever. It is this impossibility of desire that the romance of Newland and Ellen is predicated upon. Another purpose of this study was to expand this impossibility of desire to the relationship between man and woman and to interpret The Age of Innocence as a story showing the characteristics of the relationship between the sexes. The relationship between Newland and Ellen shows that there is no harmonious relationship between the sexes and that woman exists only as a fantasy object, objet petit a for man.

Marine accidents and legal violations result from mistakes and negligences of ship officers, deck officers and engine officers, during the ship navigation and lay days. Due to these accidents and violations, these officers are subjected to disciplinary actions for certification. The disciplinary action, namely certificate punishment is carried out by right rules, processes and equity. However, it is revealed that present situations are different from the principles. For the purpose of finding current states relating to certificate punishment, this study examines and analyses 737 punishment cases, accomplished in 'B' regional office of oceans & fisheries for 5 years from 2014 to 2018. The contents to be analyzed are reprimand agencies, certificate kinds, officers ranks at that time, disciplinary level, violated acts, annual reprimand state, punishment rule and it process, and disciplinary reduction levels. From such valuations various problems, such as disciplinary level deviations among laws, insufficient punishments rules, disciplinary certificate deviation, insufficient reprimand reduction rules, and lack function of crew administrative disciplinary council, are identified. Finally, methods to alleviate the problems identified will be proposed. This study, for the first time analyses the actual administrative disciplinary cases for ship officers'certificates and proposes improvement plans for its incorporation in Korea, This analysis will be useful in the examination of the study for the ship officers and making a plan for them.

The growth of mobile devices in Internet of Things (IoT) leads to a number of intelligent buildings related IoT applications. For instance, home automation controlling system uses client system such web apps on smartphone or web service to access the home server by sending control commands. The home server receives the command, then controls for instance the light system. The gateway based RESTful technology responsible for handling clients' requests attests an internet latency in case a large number of clients' requests submit toward the gateway increases. In this paper, we propose the design tasks of the IoT gateway for handling concurrency events. In the procedure of designing tasks, concurrency is best understood by employing multiple levels of abstraction. The way that is eminently to accomplish concurrency is to build an object-oriented environment with support for messages passing between concurrent objects. We also investigate the performance of event-driven architecture for building IoT gateway using node.js on one side and communication protocol based message-oriented middleware known as XMPP to handle communications of intelligent building control devices connected to the gateway through a centralized hub. The Node.JS is 40% faster than the traditional web server side features thread-based approach. The use of Node.js server-side handles a large number of clients' requests, then therefore, reduces delay in performing predefined actions automatically in intelligent building IoT environment.

As we live a life increasingly mediated by computers, we often outsource our critical judgments to artificial intelligence(AI)-based algorithms. Most of us have become quite dependent upon algorithms: computers are now recommending what we see, what we buy, and who we befriend with. What happens to our lives and identities when we use statistical models, algorithms, AI, to make a decision for us? This paper is a preliminary attempt to chronicle a historical trajectory of judging people's economic and moral worth, namely the history of credit-rating within the context of the history of capitalism. More importantly this paper will critically review the history of credit-rating from its earlier conception to the age of big data and algorithmic evaluation, in order to ask questions about what the political implications of outsourcing our judgments to computer models and artificial intelligence would be. Some of the questions I would like to ask in this paper are: by whom and for what purposes is the computer and artificial intelligence encroached into the area of judging people's economic and moral worth? In what ways does the evolution of capitalism constitute a new mode of judging people's financial and personal identity, namely the rated self? What happens in our self-conception and identity when we are increasingly classified, evaluated, and judged by computer models and artificial intelligence? This paper ends with a brief discussion on the political implications of the outsourcing of human judgment to artificial intelligence, and some of the analytic frameworks for further political actions.

When using a distributed system, it is very important to know the intention of a target ship in order to prevent collisions. The action taken by a certain ship for collision avoidance and the action of the target ship it intends to avoid influence each other. However, it is difficult to establish a collision avoidance plan in consideration of multiple-ship situations for this reason. To solve this problem, a Distributed Stochastic Search Algorithm (DSSA) has been proposed. A DSSA searches for a course that can most reduce cost through repeated information exchange with target ships, and then indicates whether the current course should be maintained or a new course should be chosen according to probability and constraints. However, it has not been proven how the parameters used in DSSA affect collision avoidance actions. Therefore, in this paper, I have investigated the effect of the parameters and weight factors of DSSA. Experiments were conducted by combining parameters (time window, safe domain, detection range) and weight factors for encounters of two ships in head-on, crossing, and overtaking situations. A total of 24,000 experiments were conducted: 8,000 iterations for each situation. As a result, no collision occurred in any experiment conducted using DSSA. Costs have been shown to increase if a ship gives a large weight to its destination, i.e., takes selfish behavior. The more lasting the expected position of the target ship, the smaller the sailing distance and the number of message exchanges. The larger the detection range, the safer the interaction.

This paper confirms whether the movement or specific operation of the muscles in the process of transferring a person from the brain can find a signal showing an essential feature of a certain part of the brain. As a rule, the occurrence of EEG(Electroencephalogram) changes when a signal is received from a specific action or from an induced action. These signals are very vague and difficult to distinguish from the naked eye. Therefore, it is necessary to define a signal for analysis before classification. The EEG form can be divided into the alpha, beta, delta, theta and gamma regions in the frequency ranges. The specific size of these signals does not reflect the exact behavior or intention, since the band or energy difference of the activated frequencies varies depending on the EEG measurement domain. However, if different actions are performed in a specific method, it is possible to classify the movement based on EEG activity and to determine the EEG tendency affecting the movement. Therefore, in this article, we first study the EEG expression pattern based on the activation of the left and right biceps EMG, and then we determine whether there is a significant difference between the EEG due to the activation of the left and right muscles through EEG. If we can find the EEG classification criteria in accordance with the EMG activation, it can help to understand the form of the transmitted signal in the process of transmitting signals from the brain to each muscle. In addition, we can use a lot of unknown EEG information through more complex types of brain signal generation in the future.

Empathy has been observed to be pivotal in enhancing both social relations and the efficiency of task performance. Empathetic interaction has been shown to begin with individuals mirroring each other's facial expressions, vocal tone, actions, and so on. The internal responses of the cardiovascular activity of people engaged in empathetic interaction are also known to be synchronized. This study attempted to objectively and quantitatively define the rules of empathy with regard to the synchronization of cardiac rhythm between persons. Seventy-four subjects participated in the investigation and were paired to imitate the facial expressions of their partner. An electrocardiogram (ECG) measurement was taken as the participants conducted the task. Quantitative indicators were extracted from the heart rhythm pattern (HRP) and the heart rhythm coherence (HRC) to determine the difference of synchronization of heart rhythms between two individuals as they pertained to empathy. Statistical significance was confirmed by an independent sample t-test. The HRP and HRC correlation(r) between persons increased significantly with empathy in comparison to an interaction that was not empathetic. A difference of the standard deviation of NN intervals (SDNN) and the dominant peak frequency decreased. Therefore, significant parameters to evaluate empathy have been proposed through a step-wise discrimination analysis. Empathic interactions may thus be managed and monitored for high quality social interaction and communication.

Objectives: This study surveyed the application of Comprehensive Dental Hygiene Care (CDHC), based on non-surgical periodontal therapy within the educational curricula of Korean universities and examined whether they recognized the need for CDHC. Methods: This study analyzed data from professors of dental hygiene practicum related subjects in 75 Korean universities. The collected data were analyzed using a Chi-square test, a Mann-Whitney U-test, and a Kruskal Wallis test via SPSS (Ver. 21.0). Results: First, the application scope of CDHC was higher in four-year universities than three-year ones with the scope of several characteristics increasing along with enrollment quota. The application scope of dental hygiene plans and actions increased with the number of patient practices in terms of periodontal evaluations. Second, the needs of the dental hygiene courses were more than 4 points in all characteristics. Although four-year universities exhibited higher points than three-year ones, there was no significant difference found except other test. Finally, all universities based their dental hygiene courses on case histories, oral and maxillofacial information, hard tissue modules, periodontal issues, and other tests, with needs also being high. Meanwhile, the application scope of the dental hygiene course evaluations was lowest in all characteristics. Conclusions: There were no significant differences in dental hygiene curricula among the universities. However, highly qualified and standardized educational courses and lectures should be developed by the Korean evaluation center for dental hygiene curricula using various studies as the basis of theory and practical classes, the total number of terms, number of case studies used, number of students per class, ratio of students to professor, and so on.
