The influence of COVID 19 has a direct impact on the education field. In the situation where non-face-to-face classes are inevitably required, interest in the learning satisfaction and intention to use real-time video conferencing is increasing. This study analyzed the effects of learner-teacher interaction, social presence, availability, self-efficacy and academic engagement as video conferencing characteristics and learner's characteristics on perceived usefulness, perceived ease of use, learning satisfaction and intention to use video conferencing. The results of this study showed that learner-teacher interaction, availability, and self-efficacy had a positive effect on perceived ease of use, and all variables except availability had a positive effect on perceived usefulness. Also, perceived usefulness and ease of use were factors that increased learning satisfaction and video conferencing use intention, and learning satisfaction was identified as variables that increased video conferencing use intention. This study has significance in that it provided various theoretical and practical implications for real-time video conferencing which will be used in many educational fields in the future through empirical analysis.

This study examined whether there was a difference in the attitude toward the recommended product and the effect on the choice deferral according to information sources. Experiment 1 examined the relationship between trust in information and product attitude, and between uncertainty and choice deferral according to information sources (AI chatbot vs. human). Experiment 2 examined the impact of social presence, perceived personalization, and choice deferral according to whether anthropomorphism of AI chatbots or not. The research results are as follows. First, consumers were found to have a more positive attitude toward products recommended by AI chatbots (vs. human). Second, consumers were more choice deferral whether to purchase products recommended by AI chatbots (vs. human). Third, it was found that consumers' selection of products recommended by anthropomorphic AI chatbots (vs. impersonated AI chatbots) increased. Also, the implications of this study and future research directions were discussed.

This is a study on the military costumes of Hunryeondogam, which was the center of Five Military Camps in the mid and the late Joseon dynasty. I confirmed the characteristics and system of military costumes of Hunryeondogam by document research and positive research. The military organization of Hunryeondogam was comprised of the high-ranking military officers such as Hunryeondaejang, Junggun, Cheonchong, Byeoljang and Gukbyeoljang, the mid and low ranking military officers such as Pachong, Chogwa and soldiers. And the military costume of Hunryeondogam included Gapju, Yoongbok and Goonbok for military officers and all kinds of military uniforms for soldiers. Imjin war and ritualized military ceremonies in the era of peace had influence on the military costume. Officers, for example, were wearing Dangap and soldiers were wearing Cheolgap or Pigap that depended on the branch of the army. Politically, kings in the mid and the late Joseon had organized military organizations to strengthen their royal authority. I think that the policy can be effectively seen by observing the military costume system. The qualitative differences in cloth materials and the presence or absence of patterns of Goonbok, the qualitative differences in the decoration of Jeonrip and the presence or absence of Yodae were able to distinguish the identity and the rank. An assumption can be made that these things could have been affected by social causes, such as frequent trips of the King and stable society. This cause could be influence on substitute Yoongbok with Goonbok that from the low ranking military officers to the high ranking military officers of Hunryeondogam. The societal changes in the mid and the late Joseon dynasty are reflected on the military costumes system of Hunryeondogam.

The main purpose of this study is to evaluate the awareness survey on the experience of fire fighting safety education and living safety consciousness of college students in the department of noncommissioned officer. Additionally, making provision of basic references and the effective fire fighting safety education is another important purpose of this study. In order to evaluate the awareness, the survey consist of 43 queries based on 6 queries for general characters, 9 queries for experiences of fire fighting safety education and 30 queries for living safety consciousness. The collected data from survey was analyzed using SPSS 20.0 win program. The interrelationship for general characters was confirmed using analysis of frequency, percentage, independent T-tset, ANONVA analysis, and regression analysis. The results show that the experience of fire fighting safety education and living safety consciousness of students from the combatant branch and ordnance corps are higher than those students from quartermaster corps. This may be attributed to the presence or absence of safety relevant courses on a curriculum. Therefore, the presence of safety courses on a curriculum should be one of important points for improving the experience of fire fighting safety education and living safety consciousness of these college students.

To accept the doctor's professional negligence in the medical malpractice, the mistakes, by which the doctor did not foresee the production of the results in spite of the possibility of foresight and did not avoid the production of the results in spite of the possibility of avoidance, must be considered, and to decide the presence of the doctor's professional negligence, the standard must be the attention standard of general-common doctor engaged in the same business and the same function, and the medical enviornments, the conditions, the extraordinary nature of medical behavior, and etc should be considered by the general level of medical science at the time of accident. This principlel must be applied to the medical malpractice case occurred being on duty without exception. But, because of the extraordinary nature of duty work, it is difficult for any doctor to do one's best technical practice by making all diagnosis, medical treatment with all the equipment on the same plane as the ordinary times. That cannot be also expected for any doctor to do one's best technical practice in the terms of a social idea. From this point of view looking into The Precedent case related to Medical-service person being on duty sentenced by The Supreme Court, unlike the general medical malpractice case, the presence of the professional negligence in the medical malpractice occurred being on duty seems to be decided with more consideration on the general level of medical science, the medical enviornments and the conditions, particularities of medical practice at the time of accident. Especially, the extraordinary nature of medical behavior of the medical service person being on duty in the emergency room seems to be admitted compared to that of the medical service person being on duty in ward.

In this paper, we analyze household overdue loans in Korea which has been causing serious social and economical problems. We consider customers of Bank A in Korea and focus on overdue cash services which have been snowballing in the past few years. From analysis of overdue loans, one can predict possible delays for current customers as well as build a credit evaluation and risk management system for future customers. As a statistical analytical tool, we propose a two-stage Generalized Linear regression Model (GLM) which assumes a logistic model for presence/non-presence of overdue and a gamma model for the amount of overdue in the case of overdue. We perform goodness of fit test for the two-stage model and select significant explanatory variables in each stage of the model. It turns out that age, the amount of credit loans from other financial companies, the amount of cash service from other companies, debit balance, the average amount of cash service, and net profit are important explanatory variables relevant to overdue credit card cash service in Korea.

Objective: The purpose of this study is to apply exercise learning effect to various subjects through training effect and information accumulation based on verification of the effect on dumbbell curl exercises applied with virtual reality. Method: To analyze the effect on the dumbbell curl exercise in the virtual environment, a total of 20 persons with 10 males and 10 females who does not have orthopedics diseases were selected. The dumbbell weight of the subjects was set to a weight of 70% strength of 1RM. At this time, the virtual environment situation was set to four types; presence/absence of virtual environment, preferred colors, and unfavorable colors to perform dumbbell curl exercise. The anaysis of muscle activity was conducted by adhering four surface electrodes (Biceps Brachii, Triceps Brachii, Brachioradialis Muscle, Extensor Carpi Radialis Longus Muscle) on the right upper limbs. Independent sample t-test using SPSS (24.0) program was carried out to analyze average values and standard deviations for each variable depending on the presence/absence of virtual environments and changes in color (preferred colors, unfavorable colors) and the level of significance was set to a=.05. Results: In the eccentric contraction, males showed high muscle activity in the Biceps Brachii under virtual reality. On the other hand, females had high muscle activity in the Biceps Brachii in the absence of virtual reality. Also, in case of a change of colors in the virtual environment, females had the high muscle activity in the unfavorable color in the eccentric contraction. Conclusion: During the dumbbell curl exercise, results of different exercises present depending on gender. When males put VR on and performs a basic dumbbell curl exercise, the effect of Biceps presents Brachii for them while exercising in unfavorable colors. However, since it is the basic research data of muscle exercise using virtual reality, it is necessary to verify whether or not it is effective for myopachynsis through long-term training rather than unity.

The purpose of this study is to understand the history of nursing and present a new direction of nursing by elucidating the role of nurses in the process of social meaning and change of infectious diseases in modern (1876-1945) Korean society. In the past history, epidemics have caused many problems in society and have tried their best to manage them. The role and presence of the nurse began to emerge during the past time. The concept of hygiene began to be recognized for the management of epidemics, and the role and presence of nurses began to emerge at the center. It was recognized that the role of nurses in modern Korean society was an auxiliary role in the early stages. However, through specialized education and training, recognition as an expert began to spread based on specialized knowledge rather than simple care. In this study, it is significant that we have historically searched for infectious diseases causing various problems while coexisting past and present. In addition, it is significant that the new role and sense of mission of the nurses were newly illuminated.

Background: Many scientists have reported Candida species to be of great concern because of the high frequency that they colonize and infect human hosts, particularly cancer patients. Moreover, in the last decades Candida species have developed resistance to many antifungal agents. Based on this, we aimed to identify and determine the prevalence of Candida spp from blood culture bottles among cancer patients and their antifungal resistance pattern. Materials and Methods: From the blood culture bottles isolation and identification of the Candida spp were performed by conventional microbiological techniques. The in vitro antibiotic resistance pattern of the isolates was determined by CLSI guidelines. Genomic DNA was isolated and amplified. Each gene was separated by agar gel electrophoresis. Results: Identification of Candida spp was based on the presence of yeast cells in direct examination, culture and DNA extraction. Of the 68 blood samples collected during the study period (April 2013 to October 2013), five (7.35%) were positive for the presence of Candida spp, 2 (40%) of which were identified as Candida albicans and 3 (60%) were Candida non-albicans. Conclusions: High resistance to amphotricin B was observed among all the Candida non-albicans isolates. Regular investigations into antifungal resistance will help us to get an updated knowledge about their antibiotic resistance pattern which may help the physician in selecting the antibiotics for empirical therapy.

Standard makers in both private and public sectors have been increasingly mandating security standards upon organizations to protect organizational digital assets. A major issue in security standardization is that standards often cannot regulate all possible security efforts by the standard maker because some efforts are unverifiable by nature. This paper studies from an analytical perspective how a standard maker should design the standard using a verifiable security control in the presence of another related unverifiable one. We compare it with two benchmark standards; $na{\ddot{i}}ve$-standard which refers to the standard maker who ignores the existence of the unverifiable control, and complete-information standard which refers to the maker sets standards on both controls. Optimal standard and benchmark standard depend critically on how the two controls are configured. Under parallel configuration, the existence of the unverifiable control induces the policy maker to set a higher standard (the complete-information standard is optimal); under serial configuration, a lower standard is applied (neither benchmark works). Under best-shot configuration and if the verifiable control is more cost-efficient, the existence of the unverifiable control has no impact on the optimal standard (the $na{\ddot{i}}ve$ standard is optimal).
