In the GORRAM, the estimation of resource requirements for wartime equipment is based on the ELCON of the USA. The number of vulnerability groups of ELCON are 22, but unfortunately it is hard to determine how the 22 groups are classified. Thus, in this research we collected 505 types of basic items used in wartime and classified those items into new vulnerability groups using AHP and cluster analysis methods. We selected 11 variables through AHP to classify those items with cluster analysis. Next, we decided the number of vulnerability groups through hierarchical clustering and then we classified 505 types of basic items into the new vulnerability groups through K-means clustering.This paper presents new vulnerability groups of 505 types of basic items fitted to Korean weapon systems. Furthermore, our approach can be applied to a new weapon system which needs to be classified into a vulnerability group. We believe that our approach will provide practitioners in the military with a reliable and rational method for classifying wartime equipment and thus consequentially predict the exact estimation of resource requirements in wartime.

With the real museum changing from a center of viewing to a center of experience and communication, virtual museums have become independent as well as auxiliary and alternative roles for real museums. Therefore, it is necessary to review the concept and meaning of virtual museums and analyze the attributes of each exhibition type. This paper categorizes the exhibition types of virtual museums into four categories and analyzes the interaction methods of each exhibition type. The essential characteristics of interaction subjects affect all four types, but the method of virtual expression is distinguished, and the exhibition type that actively utilizes the virtuality of exhibition space and work expands the user's experience and communication. In this study, various forms and methods of construction of virtual museums can be explored by providing characteristics and considerations for each type of exhibition during the planning and construction of virtual museums.

This study shows the process of designing and directly developing an online archives exhibition platform using AR (AR online archives exhibition platform) as a method for effectively providing online archives exhibition. Furthermore, the usability of the platform developed for actual users was evaluated. Related literature analysis was conducted to derive the functional requirements of the online archives exhibition platform to be guaranteed by the archives exhibition platform. Based on the derived functional requirements, six development strategies were established for the development of an AR online archives exhibition platform. The specific development of the platform was carried out using the Unity Engine and was based on the development strategy. After that, using the developed platform, 'June Democratic Struggle History Exhibition' was planned based on the collection of the Busan Democratic Park. Based on this, this study attempted to specifically evaluate the possibility of applying the actual exhibition service of the platform. Based on this, this study specifically evaluated the possibility of applying the actual exhibition service of the platform, and the usability of the AR online archives exhibition platform based on user experience (UX) was evaluated through platform demonstration for 35 actual users. According to the evaluation results, there were requirements for supplementation due to the use of advanced technology, but the main opinion was that it will be very positive at this time when untact services are being activated due to the Corona Pandemic.

The first objective of this study was to investigate the current status of the display of traditional costumes by observing museums in Seoul ; the National Folk Museum and the Royal Museum. The second objective was to investigate the satisfaction and need of their visitors by a survey method. To collect the data, several observations were made by the author, interviews were conducted to the students whose major is related to clothing and a survey using questionaires was conducted to the consumers who visited the museum in the fall of 2000. To analyze the data, both qualitative and quantitative methods were utilized. The major results were as follows; Two museums were differentiated in the contents of display, but some of costumes displayed were overlapped. In both museums, there were few visual explanations. The visitors were highly interested in the costume display in the museum. The most dissatisfactory area was the way and contents of costume explanation. The preferred contents, method, explanation and environment of the display of traditional costumes were partially different according to visitors’, characteristics. The reforming of the display of costumes reflecting the results will increase the visitors’satisfaction and therefore strengthen the competitiveness of the museums.

The Presidential Archives collects and manages both the presidential records and historical archives related to the president which it subsequent provides to the people. Regardless of these special duties that meet the people's right to know, its awareness and study on the Presidential Archives has not been thoroughly satisfied. It is time to focus on providing service to share and utilize records and archives, as well as for preservation and management purposes. Therefore, this study proposes exhibition methods through storytelling, which is well-known, as it pursues the importance of developing various services for a more efficient usage and promotion of the Presidential Archives. This helps raise awareness about the Presidential Archives, attract group visits of children, and provides a good example for collecting archives and planing exhibitions.

차량 축계의 비틀림진동은 엔진 공회전시와 정속주행시(완만한 가감속) 및 가속페달 급조작에 따른 급격한 가감속에 대해 각각 고유한 동특성을 나타내면서 차체의 진동과 소음을 유발시킨다. 공회전시의 진동해석 및 가속페달 급조작에 따른 차량 전후 진동에 대해서는 지금까지 많은 연구가 진행되어 상당한 발전을 이룩한 반면 완만한 가감속시 차량의 전속도 구간에서의 진동해석에 대해서는 해석상의 어려움으로 인해 주로 실험에 의한 접근 방법에 의존하고 있는 실정이다. 본 연구에서는 수동변속기가 장착된 전륜구동 승용차를 대상으로 차량 전속도 구간에서 축계의 비틀림진동 해석을 할 수 있는 방법을 개발하였으며, 개발된 방법을 트랜스미션 축진동 저감을 위한 클러치 비선형특성 튜닝에 적용하였다. 본 연구에서 개발한 강제진동해석방법은 수동변속기가 장착된 모든 종류의 차량에 적용할 수 있을 것으로 기대되며 자동변속기의 댐퍼클러치 설계에도 응용될 수 있을 것이다.

The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.

Recent exhibition's paradigm is changing from the existing unidirectional oriented exhibition form to a form of interactive hands-on exhibits that viewers can get and realistically feel a variety of information. Hands-on exhibit embodies the human interface by utilizing light, sound, pressure, etc. in time and space. In this paper, we have studied the creation of fractal image by the Mandelbrot technique and proposed the interaction method for it to be converted into a variety of forms. By using the proposed method, a variety of image transformation such as printmaking effect, sketch effect, Pop Art effect can be performed, according to clicking a certain fraction on the created fractal image screen by a user mouse. Interactive image generated in this study are expected to be used for trade shows, promotional products, media art design.
