Flipped learning is necessary for modern education but quite difficult to implement. In pedagogical science, the question remains to what extent the practical work of the teacher in combination with the technologies of flipped learning will improve the quality of higher education. The aim of this article is to study the effectiveness and feasibility of using flipped learning technologies, assessing their perception by students (advantages and problems), identified an algorithm for introducing flipped learning technology in higher education institutions. Research methods. The main method is an experiment. An evaluation of the effectiveness of the study was conducted using a questionnaire and observation method. Statistical methods were used to evaluate the results of the experiment. The research hypothesis is that flipped learning allows the teacher to spend more time on an individual approach, to understand the real needs of students, and provide effective feedback, thereby improving the quality of learning and motivation of students, especially while studying complex material. The results of the study are to prove the effectiveness of the technology of flipped education in the study of complex disciplines, courses, topics. The use of flipped learning strategies improves the self-regulation of the educational process, group work skills, improves students' ability to learn, overcome difficulties. The technology of flipped learning in the presence of modern technical means and constant work on improving the level of digital literacy is an effective means for students to master complex topics and problematic issues that require additional consideration and discussion. The perspective of further research is the consideration of integrated approaches to the application of flipped learning technologies to the principles of STEAM-education, multilingual and multicultural programs, etc. It is also worth continuing to develop a set of methods aimed at enhancing the student's learning activities, the formation of group work skills, direct participation in creating the foundations of higher education.
The value of tangible assets depreciates over their useful life and this depreciation should be adequately reflected in any tax or financial reports. However, the method used to calculate depreciation can impact the financial performance of solar projects due to the time value of money. Korean tax law stipulates only one method for calculating the depreciation of solar photovoltaic facilities: the straight-line method. Conversely, USA's tax law accepts other depreciation methods as solar incentives, including the modified accelerated cost recovery system (MACRS) and Bonus depreciation method. This paper compares different depreciation methods in the financial analysis of a 10 MW solar system to determine their effect on the financial results. When depreciation was calculated utilizing the MACRS and Bonus depreciation method, the internal rate of return (IRR) was 10.9% and 16.4% higher, respectively, than when the Korean straight-line depreciation method was used. Additionally, the increased IRR resulting from the use of the two US methods resulted in a 20.5% and 27.4% higher net present value, respectively. This shows that changing the depreciation calculation method can redistribute the tax amount during the project period, thereby increasing the discounted cash flow of the solar project. In addition to increasing profitability, USA's depreciation methods alleviate the uncertainty of solar projects and provide more flexibility in project financing than the Korean method. These results strongly suggest that Korean tax law could greatly benefit from adopting USA's depreciation methods as an effective incentive scheme.

The traditional roles of leaders are to influence members and motivate them to achieve shared goals in organizations. However, leaders such as top managers and chief executive officers, in practice, do not always directly meet or influence other company members. In fact, they tend to have the greatest impact on their members through formal speeches, company procedures, and the like. As such, official speech is directly related to the motivation of company employees. In an official speech, not only the contents of the speech, but also the voice characteristics of the speaker have an important influence on listeners, as the different vocal characteristics of a person can have different effects on the listener. Therefore, according to the voice characteristics of a leader, the cognition of the members may change, and, the degree to which the members are influenced and motivated will be different. This study identifies how members may perceive a speech differently according to the different voice characteristics of leaders in formal speeches. Further, different perceptions about voices will influence members' cognition of the leader, for example, in how trustworthy they appear. The study analyzed recorded speeches of leaders, and extracted features of their speaking style through digital speech signal analysis. Then, parameters were extracted and analyzed by the time domain, frequency domain, and spectrogram domain methods. We also analyzed the parameters for use in Natural Language Processing. We investigated which leader's voice characteristics had more influence on members or were more effective on them. A person's voice characteristics can be changed. Therefore, leaders who seek to influence members in formal speeches should have effective voice characteristics to motivate followers.
The purpose of this study was to examine the perception of dental hygiene freshmen about their major and their occupational consciousness. The subjects in this study were 361 dental hygiene freshmen at three different colleges in Gyeonggi province. After a survey was conducted, the collected data were analyzed with SPSS WIN 11.5 program. The findings of the study were as follows: 1. As for their view of occupation, the students made a well-paying job a priority(M = 2.97), and looked upon an occupation as a means of living(M = 1.60). Regarding the use of the profits of dental hospitals and clinics, they believed that they should reinvest their profits in a purchase of machinery, an expansion of facilities or technical development(M = 2.00). 2. Concerning relations between their motivation of college entrance and their satisfaction with their major, 96.6 percent of those who found their major satisfactory or quite satisfactory considered it to right up with their alley. 82.6 percent of them chose their major to get a stable job, and 62.8 percent of them did it through the advice of their families, relatives or regular teachers. 59.1 percent of them did it in consideration of their college entrance examination scores. Every student who were pressed for economic reasons to choose their major were unsatisfied with it. Thus, their motivation of college entrance made a statistically significantly wide difference to their satisfaction with major(p < 0.01). 3. They got a mean of 3.10 in occupational consciousness. By sub- category, they scored highest in interpersonal and work ethics(3.19 respectively). They got a mean of 3.04 in academic ethics, and got a mean of 2.99 in professional ethics, which was the lowest mark. 4. As to connections between their general characteristics and occupational consciousness, their occupational awareness was significantly different according to their motivation of college entrance and information they acquired at the time of college entrance(p < 0.05). In regard to the relationship of their satisfaction with major to their occupational awareness, their occupational consciousness statistically significantly varied with their department, their willingness of staying as a dental hygienist, the future prospect of dental hygienist (p < 0.01).

The primary responsibility for the oral hygiene of the disabled is usually the parents. Dental care of the disabled is early detection and recovery of lesions and continuous management. For this to be successful it is necessary to use diagnostic tool that can detect the early stages of dental caries which is difficult to detect with the naked eye. It is also important to educate and motivate the caregivers on oral hygiene management. Quantitative Light-induced Fluorescence-Digital (Billuminator, Inspektor Researh Systems BV, Amsterdam, The Netherlands), which provides overall caries inspection and visual information, can be useful for caregiver education. A 3-year-old girl who was hospitalized with Pallister-Killian syndrome, Hypothyroidism visited our clinic with chief complaint of rugged upper incisors. This girl had multiple dental caries and oral hygiene was very poor. Periodic QLF-D images were taken to provide caregiver education and oral hygiene management was improved. A 13-year-old girl with cerebral palsy visited our clinic for regular check up. Using QLF-D, we explained to the parents that there is a need for treatment of dental caries, and education of oral hygiene management was conducted. Improvement of oral hygiene in the disabled can be achieved through caregiver education. QLF-D is a diagnostic device that can detects early caries by irradiating light in the visible ray area to the teeth. It can also detects microleakage of restoration, plaque and calculus without disclosing agent. Clinicians can use the QLF-D to perform a general oral examination for the disabled. Also, QLF-D can be used to store visual information and educate caregivers. The accumulation of information using QLF-D makes it possible to provide feedback on oral care of parents, which is more advantageous for caregivers education.
Cerebrovascular diseases in Korea is an important health problem since mortality and mobidity have been increased rapidly. It marked the 2nd cause of specific death rates in 1993. The subjects of the study were seventeen citizens who are using to the Oriental Medicine. The data were collected from Apr. to Oct. 1996. The researcher as a caregiver and volunteer made confidence of them and asked for their agreement on the purpose of the study. The subjects expressed their experience as openheartedly as possible. The researcher described closely the experiences of using to the Oriental Medicine with there words themselves and under the observation of the reseacher. A tape-recorder was used under the permission of the subjects to prevent the leakage of the spoken information and communication. The analysis of the data was made through the phenomenological analytic method suggested by Van Kaam, which is as follows; as an unit of description which include the subject' expressions and the researcher's observation.

The purpose of this study is to present data on the human activities responding to the physical environment of ‘Ulsan’s Grand Parks by evaluating user behavior and activity, visiting motivations, and user satisfaction. This study was conducted using multi-methods such as interviews and questionnaires surveys. The main findings of this study can be summarized in six parts as follows: \circled1 Behavior patterns showed that the users visited the park left within 30 minutes and the frequency of visits was 1 or 2 times per week. They spent their time mostly on ‘walking’ and ‘picnicking’. The users visited regardless of the seasons or the day of the week. \circled2 The priorities for improvements were analyzed as follows: the users expressed their demands for ‘shadowing facilities’ like shelters and pergolas because they used these facilities frequently. Also, the users would like an ‘event program’, ‘sign system’ and ‘guide program’. \circled3 Analysis of the the user’s perception of the park showed that they perceive the park as ‘representative source of the landscape and open space in Ulsan and place for making contact with nature. \circled4 In examining the visiting motivations of the users of Ulsan Grand Park, it was revealed that people use the park for ‘time with family and friends’, ‘to escape from city life’, ‘to relieve fatigue. As a result of factor analysis, 4 factors were identified such as ‘physical motive(MF1)’, ‘exploratory motive(MF2)’, ‘social motive(MF3)’ and ‘emotional motive(MF4). \circled5 Park users’ evaluation for park facilities showed that people are satisfied with most of the facilities and especially, they have high level of satisfaction for ‘footpaths’, ‘squares’ and ‘picnicspace’. The evaluation of the park user’s of activity reveals that they are content with nearly all the variables. Especially, they have high level of satisfaction for the variables of ‘convenience for dynamic activities’, ‘making of a beautiful atmosphere, ‘accessibility from the outside’ and, ‘convenience in group activitie. Factor analysis of the park user’s of activity revealed 5 factors such as ‘convenience and interest factor (AF1)’, ‘park maintenance, management and use program(AF2)’, ‘visual beauty(AF3)’, ‘safety and accessibility(AF4)’ and ‘crowding(AF5)’. \circled6 Regression analysis was employed to get the predictor factors of overall satisfaction with a result of 60.0%($R^2$). The variance was explained as ‘quality of the picnic space’, ‘convenience and interest factor while using the park’, ‘park program for maintain and management in the park’, ‘visually beauty while using the park’, ‘safety and accessibility of the parks’, ‘quality of the pond’, ‘crowding’, ‘quality of the square’.

When automatic speech recognition (ASR) is provided as a cloud service, it is easy to collect voice and application domain data from users. Harnessing these data will facilitate the provision of more personalized services. In this paper, we demonstrate our transfer learning-based knowledge service that built with the user-generated data collected through our novel system that deliveries personalized ASR service. First, we discuss the motivation, challenges, and prospects of building up such a knowledge-based service-oriented system. Second, we present a Quadruple Transfer Learning (QTL) method that can learn a classification model from a source domain and transfer it to a target domain. Third, we provide an overview architecture of our novel system that collects voice data from mobile users, labels the data via crowdsourcing, utilises these collected user-generated data to train different machine learning models, and delivers the personalised real-time cloud services. Finally, we use the E-Book data collected from our system to train classification models and apply them in the smart TV domain, and the experimental results show that our QTL method is effective in two classification tasks, which confirms that the knowledge transfer provides a value-added service for the upper-layer mobile applications in different domains.
