The purpose of this study was to analyze the change of body temperature and pain by application of Gaussian magnetic for the elderly delayed muscle pain. For the purpose, we selected 15 elderly women(age;$69.47{\pm}1.60$) and conducted repeated experiments. The Gaussian magnetic field area was divided into three areas (1000G, 1500G, 2000G). The applying arbitrarily manufactured magnetic field wristbands changes of body heat and pain before and after wearing Gaussian magnetic were measured and collected data were analyzed using SPSS 19.0. To examine the pre-and post-treatment differences by treatment areas, we conducted paired t-test. Group differences and interaction effects were analyzed using two-way ANOVA and Duncan post hoc tests. The significance level was set to ${\alpha}=.05$. The results are as follows. The change of body heat by the Gaussian magnetic field area showed significant differences in all three groups(P<.05). There were also significant differences in the results of group interactions and in the delayed muscle pain scale between groups(P<.05). The area with the largest difference appeared in the area of 1500G field. The 1000G-1500G Gauss field is considered to be the most ideal magnetic field for body heat and muscle pain changes. In conclusion, the Gaussian magnetic field of 1000G-1500G may affect body temperature and muscle pain in the elderly, and may have a significant impact on the quality of life in old age.

In an Ad-hoc network, a method of time synchronizing all the nodes in a network centering on one reference node can be used. A representative algorithm based on a reference node is Flooding Time Synchronization Protocol (FTSP). In the process of sending and receiving messages, predictable and unpredictable delays occur, which should be removed because it hinders accurate time synchronization. In multi-hop communications, hop delays occur when a packet traverses a number of hops. These hop delays significantly degrade the synchronization performance among nodes. Therefore, we need to find a method to reduce these hop delays and increase synchronization performance. In the FTSP scheme, hop delays can be greatly increased depending on the position of a reference node. In addition, in FTSP, a node with the smallest node ID is elected as a reference node, hence, the position of a reference node is actually arbitrarily determined. In this paper, we propose an optimal reference node election algorithm to reduce hop delays, and compare the performance of the proposed scheme with FTSP using the network simulator OPNET. In addition, we verify that the proposed scheme has an improved synchronization performance, which is robust to topology changes.

Royal tombs in Neungsan-ri had been studied several times during the Japanese Colonial era. But, conceiving the general complexion of them is difficult for lack of data and analysis of previous studies are still insufficient. Thus, necessity of new approach and understanding in Royal tombs in Neungsan-ri are emphasized by the reviewing existing studies and conservation history. The Serial numbers of the Royal tombs in Neungsan-ri has been registered arbitrarily without clear guidelines from Japanese Colonial era until present time. It means previous studies were devoid of consideration for serial number changes. And, research has shown that Royal tombs in Neungsan-ri counts at least twenty, taking No.8 tomb of recent study into consideration. Moreover, in case of eastern tombs it needs changes in the existing perception that Royal tombs in Neungsan-ri consist of only six-tombs because there was no difference between eastern tombs and central sixtombs considering the burial chamber and lacquered wooden(koyamaki) Coffin. Ultimately, current state of Royal tombs in Neungsan-ri doesn't have authenticity because they had been found and regulated in the Japanese Colonial era. Consequently, it is required to overall study into entrance to burial chamber and covered burial stone marker and exaggerated mounds, ignored another tombs other than six-tombs in the center.

Machine translation (MT) system, especially Korean-Mongolian MT system, has recently attracted much attention due to its necessary for the globalization generation. Korean and Mongolian have the same sentence structure SOV and the arbitrarily changing of their words order does not change the meaning of sentences due to postpositional particles. The particles that are attached behind words to indicate their grammatical relationship to the clause or make them more specific in meaning. Hence, the particles play an important role in the translation between Korean and Mongolian. However, one Korean particle can be translated into several Mongolian particles. This is a major issue of the Korean-Mongolian MT systems. In this paper, to address this issue, we propose a method to use the combination of UTagger and a Korean-Mongolian particles table. UTagger is a system that can analyze morphologies, tag POS, and disambiguate homographs for Korean texts. The Korean-Mongolian particles table was manually constructed for matching Korean particles with those of Mongolian. The experiment on the test set extracted from the National Institute of Korean Language's Korean-Mongolian Learner's Dictionary shows that our method achieved the accuracy of 88.38% and it improved the result of using only UTagger by 41.48%.

This paper investigated convergent factors to turnover intention among some Administrative Staff in Medical Institutions(ASMI). The survey used self-administered questionnaires for 320 administrative staffs of 27 medical institutions in the J region, selected arbitrarily from July 2, 2018 to July 27, 2018. The hierarchical multiple regression analysis shows the following results. The turnover intention of respondents turned out to be significantly higher in following groups: a group in which organizational commitment is lower, a group in which organizational loyalty is higher, a group in which exhaustion, cynicism, reduced professional efficacy, sub-areas of job burnout are higher. The results show explanatory power of 50.9%. The results of the study indicate that the efforts, to increase organizational commitment and organizational loyalty, and to decrease exhaustion, cynicism, reduced professional efficacy, sub-areas of job burnout, are required to improve the turnover intention among ASMI. These results could be used in hospital organization personnel management and industrial health education to lower the level of turnover intention in ASMI, vocational aptitude education of health care college students. In following studies, it is necessary to present and analyze the structural model affecting the turnover intention of ASMI.

Memoirs of Hadrian is a representative historical novel of Yourcenar which focuses on the personal history of the Emperor Hadrian of Rome and on his inner side. This study focuses on the love story of Hadrian and Antinous, and examines the specificity of their love in relation to the homosexual culture of ancient Greece, especially pedophilia. Through this topic, we have analyzed the causes of the tragic death of Antinous by capturing the progression of a cycle of pedophilia, a young boy (Eromenos), that grows into manhood as Erastes. This study defines the emperor's efforts to restore Antinous in his own way after a failed love, as a passion toward totality. Therefore, we see the two figures as a process of mythology in which the pie of tragic destiny is transferred to the myth of androgyny that becomes one body and one unity in pedophilia. We see this ancient myth as a concept contrasting with the sense of pedophilia of the emperor, who arbitrarily distinguished between love and pleasure, and believed that the affection calculated with calmness and indifference was a harmony of love. This study explains the intention of Yourcenar in her work to present the value of empathic love, especially sacredness and sublime, which should be a part of sensual love. It also reminds us of the importance of sagacity that a person with power must hold in the happiest and most loving moments of life.

The purpose of this study is to discuss the implicit meaning of advertising content with highly persuasive language formats from a communication perspective and its interpretation process in relation to communication education, while simultaneously developing interpretative codes for media literacy education in modern society. For a successful discussion, I assumed the narrative content of advertising content that implements a special purpose as a general conversational act, and raised the issue anew that regularity exists for implicit semantic expressions. It also said that in order for media literacy education in the present society to proceed correctly, linguistic interpretations of implicit meaning cannot be guided as a principle of communication in prior research. As a solution, we confirm that socio-cultural sharing knowledge and recognition are essential interpretation codes. For further discussion, the analysis of advertising media languages with special purposes in terms of language usage was conducted to verify the process of interpreting the implicit meaning shown in them. After analyzing the implicit advertising language that I arbitrarily typified, I found that the linguistic meaning implicit with the intention of persuading the speaker can be provided mostly as media literacy education as a framework for analysis by various information and cognitive effects. In other words, acceptors should not perform only literal interpretations in the process of interpreting the implicit meaning inherent in the media language. If guided by including native language materials and background knowledge, socio-cultural customs, and general common knowledge, efficient media literacy education can be expected.

Recently, data-driven decision-making technology has become a key technology leading the data industry, and machine learning technology for this requires high-quality training datasets. However, real-world data contains missing values for various reasons, which degrades the performance of prediction models learned from the poor training data. Therefore, in order to build a high-performance model from real-world datasets, many studies on automatically imputing missing values in initial training data have been actively conducted. Many of conventional machine learning-based imputation techniques for handling missing data involve very time-consuming and cumbersome work because they are applied only to numeric type of columns or create individual predictive models for each columns. Therefore, this paper proposes a new data imputation technique called 'Denoising Self-Attention Network (DSAN)', which can be applied to mixed-type dataset containing both numerical and categorical columns. DSAN can learn robust feature expression vectors by combining self-attention and denoising techniques, and can automatically interpolate multiple missing variables in parallel through multi-task learning. To verify the validity of the proposed technique, data imputation experiments has been performed after arbitrarily generating missing values for several mixed-type training data. Then we show the validity of the proposed technique by comparing the performance of the binary classification models trained on imputed data together with the errors between the original and imputed values.

The purpose of this study was that HPV prevention education based on the planned behavioral theory was designed to provide college students with HPV vaccine knowledge, cervical cancer knowledge, attitude toward HPV vaccination, subjective norms for HPV vaccination, perceived behavioral control for HPV vaccination, and HPV vaccination. This is an experimental study to confirm the effect on the intention to vaccinate and the behavior of HPV vaccination. The subjects were arbitrarily expressed as 32 subjects in the experimental group and 34 subjects in the control group. The collected data were analyzed by descriptive statistics, t-test, χ²-test, Fisher's exact test and repeated Measures ANOVA. As a result, the experimental group participating in HPV prevention education was compared to the control group who did not participate in HPV vaccine knowledge (t=5.66, p<.001), cervical cancer knowledge (t=4.13, p<.001), attitude (t=2.24, p=) .032 ), subjective norm (t=2.83, p=.008), perceived behavioral control (t=2.65, p=.013), and intention (t=3.91, p<.001) were significantly different. After 4 weeks of HPV prevention education intervention, there was a significant difference in the interaction between group and time course of HPV vaccination intention (F=6.95, p=.002). Therefore, it was confirmed that HPV prevention education is an educational program that can be applied to college students.

This study aims to present implications for the appropriate establishment and development of a science-authorized textbook system through an understanding of the process of selecting science-authorized textbooks and analyzing the perception of teachers. Toward this end, this study conducted interviews with five elementary school teachers who participated in the science textbook selection process, surveys on 32 teachers, and analysis on the authors of the textbooks. The result demonstrated, first, that the "opinion gathering" stage was the most important one, and a council was formed in consideration of career and major. Moreover, the evaluation standard was reorganized and used according to the situation of the school. Second, in the process of opinion gathering, the teachers used a method for reviewing the entire textbook for each teacher. Inquiry activities and textbook composition (readability) were crucially considered as internal factors, and teaching and learning materials, such as videos, were deemed extremely important as external factors. The variable of the author, which is an indicator of the reliability and expertise of textbooks, was also recognized as vital. Third, the deliberation by the School Committee and the report by the principal were recognized as the administrative final step after selection. Finally, selecting the most suitable textbooks for each grade group was recognized as more important than arbitrarily unifying textbooks for the third and fourth grades and for the fifth and sixth grades.
