The purpose of this study is to investigate the revision of the western-styled court costume in the Daehan Empire. For this purpose, 1) historical documents were reviewed, 2) one set of the court costume of Chigimgwan and another set of the court costume of Juimgwan were probed, 3) the photos of people wearing court costume were analyzed. The results of this study are as follows. First, the $14^{th}$ Imperial order of "official costume statute" had been revised in 1904, 1905 and 1907 through official gazettes. The last version of official costume statute enacted the more detail than the first rule. Second, the $15^{th}$ Imperial order of "official costume rules" had been revised in 1904, 1905, and transformed into official costume rules reform on $12^{th}$ Dec., 1906. The revision in 1905 made gold embroidery of court costume more simple than the first rule. The form of court costume was totally revised by change of the shape of adjusting on the top in the revised rule of 1906. Third, the revision in 1905 was actually manufactured and worn by the people because it can be confirmed in the relics of the court costume of $2^{nd}$ Chigimgwan in Yonsei University Museum, and the court costume of juimgwan in Kwangju Municipal Folk Museum. The relics made by the revision in 1906 had not been reported until now, but they can be confirmed in the photos left. Fourth, the sovereignity of the Daehan Empire was actually lost by $22^{th}$ Imperial family order which urged the servant having the title of nobility of Japan to wear the court costume of Japan. Therefore, the endeavor of the Daehan Empire which wanted to establish and develop the costume system of modern independent nation was discontinued.

The purpose of this study is to develop conceptualization models of reading, information, ICT, and digital literacy through conceptual differences of these literacy by reviewing and defining the concepts of literacy as well as reading, information, ICT, and digital literacy. Computer literacy has emerged as a concept that explains the phenomenon of contemporary social, cultural, and information technology development, and since then, computer literacy has since changed to IT, ICT literacy, and digital literacy. As a result of the study, a conceptualization model of the reading, information, ICT, and digital literacy was developed. In this model, these literacy whose terms have changed according to the technological development of media, have been classified as medium-centered literacy. And reading and information literacy that focuses on the cognitive process of understanding, utilizing, and evaluating texts and information is categorized as process-oriented literacy. In the digital environment, reading and information literacy is a core competence to critically think and evaluate the texts that are on media, and further research is needed to reduce the reading and the information gap among readers.

This paper described a centrifuge study in order to investigate ground-underground hollow structure interaction-induced rocking behavior in liquefied ground. Uplift of the underground hollow structures is initiated due to liquefaction in sandy grounds when the ground is exposed to a strong shaking during earthquakes because the apparent unit weight of these structures is smaller than that of the liquefied soil. In order to evaluate the dynamic behavior of the underground hollow structure and the effects of original subsoil during the uplifting, model tests were performed by changing the relative density of the original subsoil and installing an acrylic box as a trench. The results of the present study show that rocking behavior of the underground hollow structure due to shear deformation of the surrounding subsoil or lateral movement from the original subsoil contributed to large magnitude of the uplift due to strong shaking.

Recently, as the COVID-19 has spread and prolonged worldwide, the 'Untact' society is becoming routinized, and various smart technologies are leading to the spread of the 'Ontact' culture. This is because the desire of consumers to purchase a product and use the service has increased while minimizing the direct contact. In order to quickly respond to this circumstance, the percentage of the companies which are adopting Chatbot in various fields such as orders, delivery, and inquiries is increasing and they are getting a positive result. However as the demand for building Chatbot increases dramatically, there are many confusions among the companies which want to introduce Chatbot to their system, due to the lack of professional technicians and difficulties in understanding AI technologies and how to build them effectively. I believe that in the post COVID-19 era, much more companies will adopt Chatbot, and this will intensify the problem. The purpose of this study was to derive the needs for a guide on the method of buiilding a Chatbot through considering the prior research on Chatbot and analysis of the recent surge in the use of Chatbot services related to COVID-19. There are implications to presenting 5 phases of universal Chatbot implementation methodology using the platform to the stakeholders who want to introduce Chatbot to their customer so that they can understand and build Chatbot more easily and use AI Chatbot actively in response to the POST COVID-19 era.

The purpose of this study is to analyze the items related to digital reading and information literacy which were measured by PIAAC and PISA, to examine the measurement contents and methods of these literacy items, and to derive the implications for providing reading and information services for librarians at public libraries and teacher librarians. In order to solve the questions measuring digital reading literacy and digital information literacy, respondents commonly needed ICT skills as well as cognitive strategies. However, in digital reading literacy measurement items, the ability to comprehend and critically think about texts was emphasized. And in digital information literacy measurement items, the ability to use ICT skills, navigate, and evaluate whether or not to read the retrieved text was emphasized. Librarians and teacher librarians need to encourage readers to read and provide a customized competencies improvement program to reflect the performance results and characteristics of a particular group. And It is also necessary to improve and develop the library environment so that library user can understand and use library search system and the Korean decimal classification.

The purpose of this study was to devise guidelines for the kitchen workspace of the aged by examining current usage. To achieve this objective, surveys were conducted and measurement were taken between June 15 and lune 30, 2005. The data were gathered from 50 women over 65- years-old who live in the downtown and suburbs of Seoul, Korea. The collected data were processed using SPSS 12.0 for Microsoft Windows and resulted in the following conclusions: The kitchen for the aged needs to be laid out in ㄱ-shape and the refrigerator needs to be positioned prominently. The height of the work counter is relative to the user's height (${\times}0.49{\sim}056$). and the length varies depending on the available space of the house and the type of work counter needed: however it was found that it should be at least 270cm Concerning the depth of the work counter, the standard sizes (60cm) currently on the market did not cause any inconvenience. It was found that the sink must be designed to allow for some space at the bottom so as to ensure comfortable sedentary work. Also, an electrical oven was preferred over a gas-fuelled one. Finally, the height of the upper cabinet should be relative to the user's height at ${\times}0.85{\sim}1.0$ from the floor to the bottom of the cabinet.

The purpose of this study is to identify the effects of school library personnel on students' reading behaviors and to identify differences between schools on it. For this purpose, this study surveyed 5,349 elementary, middle and high school students from 154 schools across Korea, and conducted a survey on reading environment, school library, and DLS. The results of the analysis showed that the students at the school where teacher librarians works are more likely to read books, participate in various reading programs, receive more help from teacher librarians in selecting books to read, lending more books, have more experience with DLS and satisfaction with it. The differences between the schools were in the order of 'classes which school library personnel took part in,' 'number of borrowed books,' 'help in selecting books,' 'average reading time per day,' 'number of home books,' 'reading in school library.' Therefore, it is necessary to expand the placement of school library personnel and develop their professionalism in order to prevent inequality in the educational environment between schools.

Purpose: Determining the spatial structure of data is important in understanding within-field variability for site-specific crop management. An understanding of the spatial structures present in the data may help illuminate interrelationships that are important in subsequent explanatory analyses, especially when site variables are correlated or are a combined response to multiple causative factors. Methods: In this study, correlation, principal component analysis, and single and nested variogram models were applied to soil electrical conductivity and chemical property data of two fields in central Missouri, USA. Results: Some variables that were highly correlated, or were strongly expressed in the same principal component, exhibited similar spatial ranges when fitted with a single variogram model. However, single variogram results were dependent on the active lag distance used, with short distances (30 m) required to fit short-range variability. Longer active lag distances only revealed long-range spatial components. Nested models generally yielded a better fit than single models for sensor-based conductivity data, where multiple scales of spatial structure were apparent. Gaussian-spherical nested models fit well to the data at both short (30 m) and long (300 m) active lag distances, generally capturing both short-range and long-range spatial components. As soil conductivity relates strongly to profile texture, we hypothesize that the short-range components may relate to the scale of erosion processes, while the long-range components are indicative of the scale of landscape morphology. Conclusion: In this study, we investigated the effect of changing active lag distance on the calculation of the range parameter. Future work investigating scale effects on other variogram parameters, including nugget and sill variances, may lead to better model selection and interpretation. Once this is achieved, separation of nested spatial components by factorial kriging may help to better define the correlations existing between spatial datasets.

Today's Virtual Reality(VR) technology has become considerably more affordable and sophisticated with rapidly advancing computer technology. Photo-realistic visual representations along with real-time interactivity are now achievable without special programing knowledge and expensive equipment. The purpose of this paper is to establish how simple, credible user testing methods based on VR simulations can be utilized to improve design decision making towards more sensible design solutions for end-users. Results of a case study demonstrate the value of potential user-testing feedback in a simulated 3D virtual service space, i.e., restaurant interior. User feedback from the VR simulation includes preferences in table location, privacy, and values of seating preferred tables. A new design framework incorporating an empirical testing method for service spaces is presented. The overall design process, the development of the VE, and the user testing method and findings are discussed. This study provides useful guidances for future efforts in the areas where such technology may benefit to understand end-user feedbacks in design process.
