This study was intended to academically redefine the art of seal engraving of the Joseon Dynasty through seal analysis related to Kim Jeong-hui and to widely promote its excellence. Previous studies on seals were examined, and comparative studies were conducted focusing on the seals engraved by Kim Jeong-hui and the related seals. The importance of the real seal study, not the stamp, was confirmed. If there was a byeongwan on the side of the seal, it was possible to understand that Kim Jeong-hui directly carved the seal. Also, it was possible to confirm the stone quality of the seal, the method of writing, the method of layout, and the method of holding graver. The imitation seal engraved with a tool rather than hand made it easy to grasp the uncertain production intent. All were analyzed by actual tensile, so it was a possible study result. The results of this study will serve as an indicator to judge the authenticity of the seal when evaluating an ancient painting in the future.

With advances in technology, many researchers have made an effort to find out educational methods with customized instruction. The purpose of the research is to investigate i) if flipped learning is beneficial for the students taking intermediate-level English grammar and writing class compared with the traditional class, ii) if the flipped learning class is advantageous for all the score level students in terms of student achievement and iii) if the students feel motivated with the flipped learning class. T-test was utilized to determine any differences between pretest and posttest in student achievement. The result in terms of the academic achievement revealed that the flipped classroom approach for the low score group was found to be the least effective among others. In the case of flipped learning teaching method, the instructor should develop contents according to the level of learners. The development of customized contents tailored to the level of learners will enhance learners' learning achievement.

There are many problems caused by data sharing between general heterogeneous digital devices due to various interfaces. To solve this problem, this paper proposes heterogeneous data sharing with cloud service and mobile through D2D communication that supports communication between different devices. The proposed technique is used to reduce the load on the server to perform data synchronization. Also, in order to minimize data latency caused by data replication between different devices, a technique to enhance the speed of data writing with copying only the modified parts in the chunk list is adopted and cloud service model integrated with mobile environment is realized in order to minimize the network bandwidth consumed for synchronization for data sharing. Therefore, it is possible to share data in different spaces efficiently with maintaining data integrity and minimizing latency in data.

Seal is a tool to prove an individual or group. Guk-Sae and Eo-Bo uses typeface to represent their names or titles, which change from tensile to tensile and have varied from time to time. Although the Korean alphabet currently uses Hangul, it had used Chinese characters before Hun-Min-Jeong-Um was created in 1443. All seals and royal seal before the Korean Seal of State were made in Chinese characters. This thesis analyzes the concept of typography through the royal seal, and the subject of this study is 'Sugang Emperor' which is the only eight-letter version seal of the Joseon Dynasty's various royal seal. Bo-Yeong, which is shown in Bo-Myeon has artistic value with beautiful typeface and proportions, which is worth research. It examines the features of the Korean seal, analyzes and studies the typeface shape and features from the typographic perspective of the "Sugang Emperor Bo-Yeong," or writing.

The purpose of this study was to suggest qualitative improvement through various student-centered curriculum's teaching experiences focusing on physical education. For this, class diaries, memos, lesson plans, student reviews, and videos for the past four years (2017-2020) were collected and analyzed from four high schools in kyonggi-do, and six students were interviewed. The common features between each student-centered curriculum were to have many students with the purpose of entrance examination and with concern about time conflicts between class and their dinner. In contrast, the differences between each student-centered curriculum were the required level of writing lesson plan, the level of interest and role of a class supervisor, and educational expected effect of students under a given condition. In summary, pre-education experience should be required and class activity support and various evaluation methods should be also needed.

This study examined how four domains of corporate social responsibility (CSR) affect the trust and distrust of corporations and contribute to their reputation. In particular, this study examined the mediation role of trust and distrust between CSR domains and reputation. The results showed that ethical responsibility and philanthropic responsibility had influence on trust. Legal responsibility had a significant effect on the distrust. Companies that did not fulfill legal responsibilities were more likely to be distrusted. The influence of trust on corporate reputation was significant. The results of this study indicated that trust was a mediator between ethical responsibility, philanthropic responsibility, and reputation. Economic responsibility had a direct influence on reputation. Theoretical and practical implications for strategic approach in each CSR domain are discussed.

This study classifies review attributes into ratings, number of comments and image information in online shopping mall to verify their impact on brand attitude and purchase decision and e-WOM intention. Use SPSS 23.0 for frequency analysis, factor analysis and regression analysis. The results showed that review attributes have a positive effect on brand attitudes, purchase decision and e-WOM intention, but the number of comments has not affect on purchase decision. Brand attitude has a positive effect on purchase decision and e-WOM intention. Brand attitude has media effect in the relationship between ratings, image information and purchase decision, and in the relationship between review attributes and e-WOM intention. As these results, consumers don't always like to have a lot of comments. and should allow to focus on high ratings and photo reviews as much as possible when writing reviews.

This scoping review aimed to identify and categorize the available measurement options for vaginal laxity (VL), their indications of use, and whether these measurements can sufficiently provide objective clinical judgment for cases indicated for vaginal rejuvenation with many treatment options nowadays. Systematic searches were conducted on five electronic databases, manually searching articles' bibliographies and predetermined key journals with no date or study design limitations. We included all studies involving VL in their inclusion criteria, treatment indications, and outcome parameters. We used the Arksey and O'Malley frameworks as the guideline in writing this scoping review. Of the 9,464 articles identified, 66 articles and 11,258 subjects were included in the final analysis. The majority of studies were conducted in obstetrics and gynecology (73%), followed by plastic surgery (10%), medical rehabilitation (4.5%), dermatology (4.5%), and others (8%). Most studies originated from the North American region (30%). The following measurement tools were used: (1) interviews, (2) questionnaires, (3) physical/digital examinations, (4) perineometers, and (5) others. Our results suggested that subjective perception of laxity confirmed by directed interview or questionnaire is sufficient to confirm VL. Additional evaluation of pelvic floor muscle through digital examination or perineometer or other preferred tools and evaluation of sexual function through validated questionnaire (Female Sexual Function Index, Female Sexual Distress Scale-Revised, etc.) should follow to ensure holistic care to patients. Future research on the psychometric properties (reliability and validity) of commonly used measurements and the correlation in between subjective and objective measurements should be initiated before their clinical applications.

Flexible tactile sensors can provide valuable feedback to intelligent robots regarding the environment around them. This is especially important when robots such as, service robots share a workspace with humans. This paper presents a contact force measurement algorithm of a flexible tactile sensor. This sensor is manufactured by a direct-writing technique, which is one 3D printing method, using multi-walled carbon nano-tubes. An analog signal processing circuit has been designed and implemented to reduce noise contained in the sensor output. In addition, a digital version of the Butterworth filter was implemented by software running on a microcontroller. Through various experiments, characteristics of the sensor system have been identified. Based on three traits, an algorithm to detect the contact and measure the contact force has been developed. The entire system showed a promising prospect to detect the contact over a large and curved area.
