The purpose of this study was to develop the Empathy Rating Scale by a third party and examine the validity of the scale. Based on the results of the pilot study, the study 1 focused on developing Empathy Rating Scale by a third party. From the exploratory factor analysis on a total of 15 preliminary items, three fators had been derived: 'Beginning of empathy', 'Process of empathy', 'Result of empathy'. The study 2 identified its validity by confirmatory factor analysis, correlation analysis, and discriminant analysis. Those three factors indicated the reasonable fit index by confirmatory factor addition, this scale identified a significant positive relation with authenticity, emotional clarity, and intimacy. On the other hand, it indicated a negative relation with anxiety attachment and rejection attachment. Therefore, the results indicated that this scale on a total of 11 item has a reliable convergent validity. Finally, implication and limitation of this study were discussed in relation with future studies.

In this paper, we try to criticize a bias that liberal arts are not practical. First, I introduce holistic models of knowledge and constructivism in education. Second, I suggest 'linguistic turn' as another noticeable phenomenon. Language is an element of culture, but a priviledged one because culture, in itself, is linguistic. So culture is a sort of a text. We can see that liberal arts or humanities to deal with texts, contexts and languages can have an important role to read, understand and construct a world. So the rediscovery of the traditional model of the education of liberal arts like processes of graduating studies of liberal arts or humanities, is relevant to a new 'practical' model of reading and leading recent social transformations. An important point is academic contribution. And current situation called 'Knowledge-Based Society' also supports my point in another way. The situation of rapidly changing knowledge requires an education of problem-solving ability by unifying and reconstructing knowledge supporting with constructivism in education rather than the cramming system of education.

Since COVID-19's 1st pandemic came in February 2020, the demand for telemedicine grew greatly that in most countries the deregulation for telemedicine policy have been implemented in more countries. Also in Korea, with the name of 'Non-face-to-face Treatment' telemedicine began to be approved. Telemedicine having strength in chronic disease management has been effective in more and more specialties along with the recent development of ICT that it is expected to contribute to the improvement of the quality of healthcare service and creation of new treatment model. On the contrary it may also exacerbate the distortion in the hospital healthcare service industry in Korea, which is the excessive tipping toward large hospitals. So the dual promotion policy approach in which the settlement of family doctors system extensively utilizing telemedicine for chronic disease management and the support for tertiary hospitals and hospitals focusing on treating foreign patients to provide quality service using telemedicine technology are pursued simultaneously are recommended.

It is debated whether the time value of bulk cargo should be reflected in the economic assessment of SOC investments. The purpose of this study is to present the basic considerations that should be addressed to reflect the time value of bulk cargo. The study first tried to understand the status of foreign countries, related research cases, and the limitations of applying findings to the domestic situation. Further, the method of reflecting the time value of bulk cargo, as well as the extent to which it is reflected, varies across countries. Furthermore, the reflection of the time value derived from the transport selection model remains a controversial issue. To overcome these limitations, this study suggests basic environment considerations to reflect time. Although the need to reflect the time value of bulk cargo is fully recognized, it seems that there are issues that need to be reviewed and solved before its actual implementation. To complement this, further research needs to be conducted, and it is expected that more clear guidelines will emerge.

This paper presents the design of a JPEG-LS codec for lossless image compression from AR/VR device. The proposed JPEG-LS(: LosSless) codec is mainly composed of a context modeling block, a context update block, a pixel prediction block, a prediction error coding block, a data packetizer block, and a memory block. All operations are organized in a fully pipelined architecture for real time image processing and the LOCO-I compression algorithm using improved 2D approach to compliant with the SBT coding. Compared with a similar study in JPEG-LS, the Block-RAM size of proposed STB-FLC architecture is reduced to 1/3 compact and the parallel design of the predication block could improved the processing speed.

The number of domestic e-commerce transactions has been breaking its own record by an annual average growth rate of over 20% based on volume for the past 5 years. Due to the rapid increase in e-commerce market, retail companies that have difficulty meeting consumers in person are in fierce competition to take the lead in the last mile service, which is the only point of contact with customers. Especially in the delivery area, where competition is most intense, the role of the fulfillment center is very important for service differentiation. It must be capable of fast product preparation ordered by consumers in accordance with the delivery service level. This study focuses on the order picking system for rapid order processing in the fulfillment center as an alternative for companies to gain competitive advantage in the e-commerce market. A mixed integer programming model was developed and implemented to optimize the stock replenishment in order picking facilities. The effectiveness was scientifically and objectively verified by simulation using the actual operation process and data.

This paper presents an on-line finite element model updating method for in-service structures using measured data. Conventional updating methods, which are based on numerical optimization, are not efficient for on-line updating because they generally require repeated eigenvalue analyses until convergence criteria are met. The proposed method enables fully automated on-line finite element model updating, almost simultaneously with vibration measurement, without any user intervention or off-line procedures. The automated covariance-driven stochastic subspace identification (Cov-SSI) method is utilized to identify modal frequencies and vectors, and the identified modal data is fed to the neural network of the inverse eigenvalue function to produce the updated finite element model parameters. Numerical examples for a wind excited 20-story building structure shows that the proposed method can update the series of finite element model parameters automatically. It is also shown that sudden changes in the structural parameters can be detected and traced successfully.

This study examined the factors affecting the intention of the public to share electronic medical records(EMR) based on the theory of reasoned action and the privacy calculus model. It also investigated whether the purpose of EMR sharing varies depending on personal characteristics, such as the degree of interest in health and personal medical history. According to an online survey of 145 people, altruistic enjoyment, awareness of personal information protection, recognition of legal and institutional roles, and interest in health had a positive impact on the level of EMR sharing, and trust in hospitals positively adjusted the relationship between recognition of legal and institutional roles and sharing intentions. Accordingly, we confirmed that the public recognized the role of the government and hospitals in the sharing process as necessary. The public interest benefits of sharing are critical to activating public participation in the sharing of EMR, and it is also essential to prepare guidelines that legally guarantee the security and proper use of EMR.
