Although the human body is a biological subject with definite and distinctive physical features, its actualization and perception differs among societies. The aesthetics of the human body are based on diverse cultural perceptions that must be considered prior to design development. This study establishes the foundations of newly adopted concepts of beauty that are presumed to have been established in the first half of the twentieth century that continue to affect our mindset even now. The research includes human figures in the articles of women's magazines and cosmetic advertisements in the early $20^{th}$ century. The results are as follows: First, the change of perception in the human body: Instead of being a subject of preservation, the body has become a subject of sculpture with emphasis on health in the 1920's and on beauty in the 1930's. The recognition of the importance of the body has created intensive attention on physical training and an increased sense of hygiene. The body exposed to the public perceives itself through the eyes of others that alter one's own perception of oneself as well as become a target of evaluation. There is an additional emphasis on the exotic eroticism of a passive subordinate. Western culture became the standard for modernization along with the dissociation of traditional standards and values. Through the effect of education and western thinking, the awareness of women's rights and self-appreciation was developed. Second, ideal beauty can be summarized as follows: Unprocessed natural beauty was extolled as ideal in the 1920's, but the 1930's, it highlighted big eyes and an aquiline nose that are the characteristics of western women. Taking care of one's appearance was recognized as an important value for every social class. Cosmetics and skin care treatments promised soft and white skin. In contrast to western cosmetics, dark and shiny hair was highly favored. Exercising and traveling, differing seasonal and regional skin treatments were also widely accepted. In its initial stages, the research had originally assumed that the beginning of the twentieth century would be a time in which traditional concepts of beauty and new, westernized aesthetics coexisted. However, as the research progressed, it was clear that the idea of beauty had already adopted occidental ideals by that time. Thus, it seems necessary to continue the study on the shifting paradigms of beauty that must have occurred in the nineteenth and late twentieth century.

Although digital hearing aid algorithms have been developed to compensate hearing loss and to help hearing impaired people to communicate with others, digital hearing aid user still complain about difficulty of hearing the speech. The reason could be the quality of speech through digital hearing aid is insufficient to understand the speech caused by feedback, residual noise and etc. And another thing is masking effect among formants that makes sound quality low. In this study, we measured the masking characteristics of normal listeners and hearing impaired listeners having presbyacusis to confirm masking effect in speech itself. The experiment is composed of 5 tests; pure tone test, speech reception threshold (SRT) test, word recognition score (WRS) test, puretone masking test and speech masking test. In speech masking test, there are 25 speeches in each speech set. And log likelihood ratio (LLR) is introduced to evaluate the distortion of each speech objectively. As a result, the speech perception became lower by increasing the quantity of formant enhancement. And each enhanced speech in a speech set has statistically similar LLR, however speech perception is not. It means that acoustic masking effect rather than distortion influences speech perception. In actuality, according to the result of frequency analysis of the speech that people can not answer correctly, level difference between first formant and second formant is about 35dB, and it is similar to result of pure tone masking test(normal hearing subject:36.36dB, hearing impaired subject:32.86dB). Characteristics of masking effect is not similar between normal listeners and hearing impaired listeners. So it is required to check the characteristics of masking effect before wearing a hearing aid and to apply this characteristics to fitting.

The purpose of this study is to analyze the perception of non-face-to-face online undergraduate lectures experienced by foreign learners, to identify problems of online lectures, and to suggest improvements. For this study, the perception of online lectures was investigated and analyzed by foreign undergraduate students who took online lectures at A and B universities. Through this, I explored the design direction, complementary measures, and direction of online lectures to be held at Korean universities in the future. As a result of this study, non-real-time lectures through E campus were recognized as advantages in that they could learn repeatedly and listen to lectures at home., Real-time lectures using Zoom were recognized as an advantage of being able to communicate between professors and learners. Both types of online lectures had many tasks and had difficulty in focusing on the lecture until the end. In the future, it was found that the amount of lecture contents and the amount of tasks should be reduced and the condition and sound quality of the lecture image should be improved. As for the evaluation method, they preferred online evaluation rather than offline evaluation, and they preferred relative evaluation rather than absolute evaluation. The results of this study were able to closely understand how learners perceive online lectures. Also, when conducting online lectures, I was able to know the points that need to be improved in the future. The results of this study are expected to contribute to the design direction of online lectures and the development of online contents at each university.

The purpose of this study is to suggest directions for enhancing competitiveness of corporate management by examining how individual creativity and organizational members' value innovation culture perception affect innovation behavior and knowledge sharing, and how innovation behavior and knowledge sharing affect organizational innovation performance and management outcomes In order to achieve these research objectives, the measurement variables of each variable were extracted through previous research and 423 valid samples were analyzed using SPSS 22.0 statistical package program and LISREL 9.1 to verify a hypothesis. As a result of this study, it was found that the creative thinking skills of the individual creativity, the meaningful tasks of the value innovation culture recognition, and the risk - taking culture have a significant influence on the innovation behavior. Only the meaningful tasks of organizational members' value innovation culture perception affect knowledge sharing. Innovation behavior has a significant effect on knowledge sharing and innovation performance, but not on business outcome. In addition, knowledge sharing has no significant effect on innovation performance but has a significant effect on business performance. Finally, we confirmed that innovation performance has a significant effect on management outcome.

In this study, we investigated the change in science core competency perception of high school students and the reason for change when science inquiry classes were conducted using eight 'skills' of the 2015 revised science curriculum. Fifteen first-year high school students in Jeollanam-do participated in the science inquiry class of this study, and the class was conducted for 20 hours (5 hours a day for four days). The inquiry activities used in the class consisted of four activity stages (research problems, research methods, research results, and conclusions) and each stage was constructed to include at least one 'skill (Problem Recognition, Model Development and Use, Inquiry Design and Performance, Data Collection, Analysis and Interpretation, Mathematical Thinking and Computer Application, Conclusion and Evaluation, Evidence-based Discussion and Demonstration, and Communication)'. As a result of the study, students' perception of the five science core competencies increased statistically significantly at the significance level of 0.01 through inquiry classes and more than 93% of students recognized that their science core competencies improved through the classes. However, since the class of this study was conducted for a small number of students, it is difficult to generalize the effect of the class, and so it is necessary to conduct a quantitative study for many students.

The purpose of this study was to examine the influence of the disaster perception and satisfaction level of volunteer fire-fighters on the continuity of their volunteering. The 163 subjects in this study were selected from male and female volunteer fire-fighters who resided in urban and rural regions in Gangwon Province. After a this survey was conducted, the collected data were analyzed by a statistical package SPSS WIN 20.0, and frequency analysis, correlation analysis and multiple regression analysis were made. The level of statistical significance was all set at p<.05. The findings of the study were as follows: First, as for the correlation of disaster perception, satisfaction and volunteering continuity, perception of disaster countermeasures, satisfaction and the level of participation were negatively correlated with one another, and there was a positive correlation among disaster training, disaster preparation, regional disaster, the period of volunteering, and will of persistent volunteering. Second, as for perception of disaster, the volunteer fire-fighters were asked a question about disaster countermeasures, and the largest group replied they were partially aware of the countermeasures. Concerning questions about disaster training/education experience and triage, the biggest group replied they underwent the training and knew about triage on the whole. Regarding questions on the emergency contact system and emergency work schedule, they knew about the two in general. As to a question on the occurrence of human disaster, the greatest group answered that they knew about it yet not well. Third, in regard to the impact of satisfaction level on volunteering continuity, the period of volunteering was affected by needs for experience, social contact and social recognition among the subfactors of satisfaction level, and will of persistent volunteering was under the influence of social contact and achievement needs. The level of persistent volunteering was affected only by needs for experience and achievement needs.

The present study explored the agenda setting effects of replies called "Daet-Gul", and perception of the news replies. This study has established three research questions: 1) the recognition of the online communication 2) the degree of the reading and writing on online spare 3) the amount of the effects on the online communication. This study is performed using survey method. The survey results indicated in that the participants are very passive readers and writers on the online spare. In addition, the survey repliers evaluated that replies' mechanical device and antigravitational speed have high score, whereas they marked low store in the content and credibility of 'the replies. Therefore, they did not estimate the effects of the replies highly. All the results indicate that 'the replies' is not the fundamental factors of the deliberative democracy. It's because online communication with 'the replies' are thought to be fated the abuse and slander. Therefore, it's essential to improve the online communication with 'the replies', through the introduction of the 'trackback', which is a sort of the 'remote replies'

The usage status of trousers as school uniform for girl's middle and high school students in Seoul and the perception on trousers as school uniform were analyzed. Students who wore 'skirts only' were the greatest and students who wore 'trousers only' were higher in the case of winter uniform than in summer uniform. The most popular reason to wear skirts was 'because most of their fellow students wore skirts' in both winter and summer. The main reason for wearing trousers was 'because it was easy to cope with changes in temperature' in winter and 'because it allowed more comfortable movements' in summer. Students who wore trousers were generally satisfied with wearing trousers as school uniforms. However, they showed a low degree of satisfaction about design and color of trousers. The students preferred slim and straight trousers, and black col or with beige and blue being the next color. Students in general had low level of recognition for the need to wear trousers. Students perceived trousers as being cold-proof and comfortable for physical activities. But they also perceived that trousers were not suitable for improving their appearances and expressing their characteristics. Especially, the students who wore trousers tended to think that trousers reduced their cares for their personal attire and that trousers were good for wearing after school, but the students who did not wear trousers were found to think contrary.

The purpose of this study was to be used as basic data for the development of future-type curriculum in health. The awareness and preparation of the forth industrial revolution were surveyed on 280 college students in health departments preparing medical technicians. A self-written structured questionnaire was used for data collection, and the recognition of the forth industry revolution was 2.74, 3D printing (3.59) was high, and neural network machine learning(2.33) was the lowest. Students majoring in Physiotherapy (3.00) had the highest perception, and those majored in Dental engineering(2.37) had the lowest perception, and there was a difference in the degree of perception of IoT by major (p=0.024). For the forth industrial revolution, 54.5% of students are preparing, and lack of interest (42.9%) is the most difficult reason to prepare, and 50.6% of educational experience and 60.9% of VR&AR game experience have experience. In the era of the forth industrial revolution, job loss (38.7%) was high, and the required competency was creative capacity (50.6%). Therefore, it is necessary to develop a curriculum related to the fourth industrial revolution and apply teaching methods that can increase the awareness and preparation of health college students in the era of the fourth industrial revolution.
