Value Engineering(VE) is an organized effort to create the most value through a functional analysis and creation of alternatives. Depending on the VE job plan, a VE Workshop must be performed in a certain place within a certain period of time. A VE Workshop, which is an organized activity that aims to create the best value through functional analysis and creation of alternatives, should be held in a certain place and at a scheduled time according to the VE job plan. In the Pre-Study, VE Study and Post-Study phases of VE, functional assessments, performance evaluations and idea evaluations are driven by variable management techniques and analysis methods, respectively. Generally, VE is executed for about 3 to 5 days in a particular place to create value. However, there are many problems associated with limiting all VE processes to a specific place and schedule. Moreover, in Korea, VE teams are required to finish all VE processes in a limited time because of the short duration of VE workshops, the necessity of which has been overlooked. Therefore, an efficient VE support system is required to resolve the problem of time and space limitations. In this study, a VE support system based on the Mobile environment was developed to support the VE Workshop process. This VE support system enables participants to review design documents, drawing sheets and all VE-related documents using mobile devices. After the Workshop, participants can conveniently rearrange the result(evaluation of function and ideas) at the workshop. Not only can the members of VE team can review the design documents, drawing sheet and all VE-related documents in the step before the workshop, but also the result(evaluation of function and ideas) of the workshop can be easily rearranged in the phase after the workshop under the developed supporting system using mobile devices.

The purpose of this study is to design an effective innovation model for communication-centered public services, based on the case of Korea Midland Power Co., Ltd (KOMIPO). This study analyzed customer and employee participation activities at KOMIPO, focusing on communication activities to derive the best practices. The study comprised of the following stages: (1) Preparation stage to assess the current situation and promote change management; (2) Problem-solving stage for improving public services; (3) Problem-solving stage for improving work processes; (4) Problem-solving stage for strengthening collaboration, and (5) Design stage for an innovation model. Based on the results of this study, an innovation model was developed for public services by applying the double-diamond design process. The proposed model presents a process structure, which is derived through an iterative process of primary divergence (discovery) and convergence (definition), and secondary divergence (development) and convergence (delivery). This study also proposed the possibility of applying the Idea-Power-Plant activities of KOMIPO's best practices to the proposed model. While this study proposed an innovation model for communication-centered public services through the analysis of a specific public company, the results of the study provide broad insights for effective operations management through efficient communication based on the participation of customers and employees in public institutions.

In this paper, we introduce the concept of the cube satellite Chungnam National University Laser Unity Bus (CLUB), which can provide an integrated infrastructure for various ground-space laser applications. With the advent of the new space era, the rapid expansion of space utilization has begun to reveal the limitations of conventional radio frequencies. As space missions diversify, lasers are garnering attention as a viable alternative. Between ground and space, lasers are applied in various fields including satellite laser ranging (SLR), laser weapons, and laser communication. However, laser used between the ground and space are significantly influenced by the Earth's atmosphere. Consequently, understanding the atmospheric effects on laser propagation is crucial. In particular, atmospheric turbulence, which refracts and distorts laser beams, intensifies closer to the Earth's surface, exerting a greater impact on the uplink than on the downlink. While downlink verification is facilitated by ground detection, verifying the uplink poses challenges due to the necessity of space-based detection. In response to these challenges, we propose the idea of cube satellite as a means to enhance understanding and verification of laser propagation in the uplink. Additionally, we present the results of conceptual design by analyzing requirements, focusing on mission design of the CLUB cube satellite, following the stages of systems engineering for systematic cube satellite development.

The Seoul metropolitan government announced an open design competition for reconfiguring the annex building of the National Tax Service Building site on Sejong-daero as a space for citizens to commemorate the 70th anniversary of Korea's liberation. The site, built during the Japanese colonial period, has been in use ever since. This study, as one of the entries for the competition, described the strategy and design contents by drawing the concept and main points of the design through an analysis of the historical context of the site. As the guidelines instructed to consider the value of the Sejong-daero area and the cultural heritage through a comprehensive analysis, this study specified the site as a place connecting the past, present and future. Since the foundation of the Joseon dynasty, the Korean Empire and the Japanese colonial period, Sejong-daero has been a main site for important events and activities along with the change of the city structure. Jungdong, to the rear of the site, was a place for adopting new culture during the beginnings of modern Korea, while adjacent places like Duksugung, the Anglican church, and the Seoul City Council building have also been historic urban landscapes of the historical layers of time as the city has changed. When Gojong announced the Korean Empire, the city structure was remodeled with this site as the center along with Sogong-ro, Wongudan and so forth. In this study, public interest stated in the guidelines was focused and the relevance of the road and the plaza was considered from the view of an historic urban landscape by a comprehensive analysis with Sejong-daero as the center. The restoration of public interest was to be drawn as the concept of the object site by considering the current status and the change around the site and Jungdong at the rear. Returning the site to the public is ambiguous with the relevance of the restoration of public interest and as the symbol of the idea of the Korean Empire by Gojong's announcement. The object site, having the characteristic of being returned to the public, must ensure public interest and therefore the design strategy has been established with the keywords of openness, connection and void. As a result of a review of the alternatives, a plan for a square has an 8% slope, just as the original site does, and provides ramps for convenient access for all, including the disabled and the elderly, and is connected to the grounds adjacent. No construction is allowed at the terrace square of the Anglican church level and the main square connected to the pedestrian street, so a variety of modern city utilization can be done. The value of the site at which this design is aimed shall be given back to the public with the concepts of modern democracy, independence, and the vision of Gojong by reinterpreting the space from a modern viewpoint. This study focused on the processes of establishing a main concept and strategy rather than the content of the design details, and the suggestion is meaningful in that the design for the object site with historic backgrounds and the layers of time can continue to be grown.

The purpose of this study is to interpret the elegant dressing visualized in modem fashion on the basis of the concept of elegance in dress and its aesthetic characteristics from the holistic viewpoint. Elegance in dress is based upon the idea of aristocratic taste cultivated by good breeding, considering from the documentary study. It is expressed visually through not only the carefully contrived dress but also a sort of aura of dressed body with skillful ease. The aesthetic values of elegance consist of luxury, nobility, refinement, femininity, harmony. To grasp the trends of elegant styles since 1990s, contents analysis of the articles related to elegance in Vogue has been done. As a result, they have been classified into four groups of elegant styles which are Classic, Elaborate Couture, Soft Minimalism, Kitsch Elegance. Classic Elegance and Elaborate Couture Elegance represent traditional ones with conservative viewpoint. Soft Minimalism Elegance is a modem version of elegance. According to postmodernism as a open system, even kitsch has been refined to keep accompany with elegance fur aristocratic taste of high class. As a result of this study, in fashion from the 16th century to the first half of 16th century, elegance has been one of the significant aesthetic categories, resulting from the absolute domination of taste of high society. However in the end of 20th century it seems to start to fade in fashion trends such as mass fashion, youth culture, casual fashion etc. Rather, it can be thought that elegance has been expressed as one of the aesthetic values in dress, by virtue of its value of high class as well as its conservative stability.

As fashion is a visual symbol that reflects age and culture, cosmetics and beauty are other products of fashion that move the time. A dominant designer of 20th century Chanel does not merely stand for a design innovation of fashion industry that created a vogue. With liberation from corsets that cruelly exaggerated and suppressed female body, meaning of style in modern fashion could be found not only in clothing but also in make-up and hair style. Simplest possible comfort was aimed for, and philosophical concepts of minimalism, modernism and dandyism were incorporated with clothing, cosmetics, perfume, make-up and hair style to establish aesthetical concept of total fashion. Chanel thought of cosmetics as an accessory with essential role and although her philosophy on cosmetics and beauty is not as well known as her clothing style, the authors believe that understanding such philosophy will become an important stepping stone for accurately understanding Chanel style. The purpose of this study is to firstly illuminate the idea that cosmetic beauty can be studied with artistic and philosophical background in addition to its functional side and to secondly investigate the reason why Chanel style is being loved by women with such durability over time and space and with what tempo fashion is connected with cosmetic beauty culture and develops. Third, by studying the ways in which characteristics of Chanel's fashion philosophy are expressed in cosmetics and beauty culture, this study aims to accurately understand Chanel's philosophy on cosmetics and beauty. The meaning of this study can be found by showing the evidence that globalization of Korean fashion beauty culture can be achieved only when cosmetics and beauty culture moves with an intimate connection to clothing culture.

The purpose of this study was to identify egonomy tendency on their self-makeup and appearance management behavior of university women in Jeonbuk province. A self-administered questionnaire was used for data collection. Frequency analyses, reliability analyses, cross-tabulations and multiple regression analyses were used. Factors of university women's egonomy tendency were individuality, value, luxury good, style, design, appearance, and economic feasibility. University women were classified into the egonomy retarde group(G1), the value pursuing group(G2), the economic feasibility pursuing group(G3), and the highly egonomy pursuing group(G4). G1 were indifferent to their makeup methods and appearance management, had the least experience in buying recommended cosmetics or idea cosmetics. G2 invested time and efforts in makeup and managed their appearance with cosmetics or folk remedies, had less experience in buying artist brand cosmetics. G3 performed makeup frequently, were not much interested in appearances while showing the most frequent appearance management behaviors using cosmetics of folk remedies, and spent small amount of money to buy cosmetics. G4 showed high frequencies of all factors of self-makeup and appearance management behaviors, had the most experience in buying artist brand cosmetics and spent much amounts of money to buy cosmetics. Self-makeup behavior was affected by their tendencies to pursue individuality, values, appearance and appearance management behavior was affected by their tendencies to pursue luxury goods, appearance, and economic feasibility.

This paper suggest an effective idea to implement an low area multi-mode one dimension transform block of HEVC(High Efficiency Video Coding). The time consuming multiplier path is designed to operate on low frequency. Normal multipliers dealing with variable operands are replaced with smaller constant multipliers which do the product with constant coefficient and variable only using shifters and adders. This scheme increases total multiplier counts but entire areas are reduced owing to smaller area of constant multiplier. Idle cycles caused by doubled multipliers enable to use multi-cycle paths on the cycle eating multiplier data path. Operating frequency is lowered by multi-cycle path but total throughput is maintained. This structure is implemented with TSMC 0.18 CMOS process library, and operated on 186MHz frequency to process a 4k($3840{\times}2160$) image. Max operating frequency is 300MHz.

Computer programming in computer education draws much attention recently. Encouraged by the increased tendency of acquiring logical ability and creativity through learning, various attempts have been made to develop them through learning computer programming in the area of computer education as well. The fact that a computer program is the representation of a computer algorithm expressed in a computer language makes us realize that the devise of a logical method for a solution - i.e., the design of an algorithm - is the key to the solution of a problem. Recognizing the importance of computer algorithm would lead us to such a point that systematic investigations for directional establishment for algorithm education are necessary. We observe that researches on teaching computer algorithm have concentrated mostly on specific problems such as sorting and searching, which can be characterized as problem-dependent and individual. In this paper, the idea of conceptual algorithm is stated from the standpoint of conceptual types of problem-solving methods which are considered as problem-independent and collective. A novice approach to algorithm education based on the characteristics of types of conceptual algorithms is proposed for the purpose of developing systematic, problem-independent, algorithmic problem-solving capabilities of learners, which is widely different from the current methods of individual and problem-dependent algorithm education.
