본 논문에서는 신뢰성 기반 최적설계(RBDO)에서 성능함수의 비선형성을 고려한 효율적인 차원감소법(DRM)을 제안한다. 차원감 소법은 적분직교점과 가중치를 사용하여 1차 신뢰도법(FORM) 보다 더 정확하게 신뢰도를 평가하는 반면 성능함수를 추가로 해석해 야하기 때문에 적분직교점의 개수가 증가하면 효율성이 저해된다. 본 논문에서는 신뢰성 기반 최적설계에서 성능함수의 비선형도를 평가하고, 비선형도에 따라 적분직교점의 수를 결정하는 기준을 제안한다. 이를 통해 신뢰성 기반 최적설계가 진행될 때 반복마다 적 분직교점의 수를 조절하여 차원감소법의 정확도는 유지하면서 계산의 효율성은 개선하는 방안을 제안한다. 성능함수의 비선형도 평 가는 최대가능목표점(MPTP) 탐색에 사용한 벡터 사이의 각도를 통해 이루어지며, 수치 테스트를 통해 비선형도에 따른 적절한 적분 직교점의 수를 도출하였다. 2차원 수치예제를 통해 개발된 방법이 차원감소법이나 몬테카를로 시뮬레이션(MCS)의 정확도는 유지하 면서 효율성이 향상된다는 것을 확인하였다.

Engineering design primarily focuses on product improvement through enhancing existing functionalities, integrating features, or adding new capabilities. In other words, it can be said that more design(adaptive design) changes to existing products based on benchmarking with competing products, differentiation strategies, changes in customer needs, etc. are actually performed rather than developing new products that did not exist before. Especially in the case of custom production, such as ships or buildings, a significant portion of actual design work involves modifying and adjusting past performance data according to the current customer's requirements. Therefore, design methods should be developed in a way that effectively supports these processes. Therefore, in this study, as QFD (Quality Function Deployment) ‘analysis of existing products’ and ‘creation of new alternatives’ is supported in Marine Concept Design with AHP (Analytic Hierarchy Process) techniques such as ‘Value Evaluation in Analysis Work’ and ‘Design Alternative Evaluation’, as a result, basic research was conducted on whether it could be used as a tool to effectively support the flow of the design process.

Taguchi method is one of the most popular approaches for design optimization such that performance characteristics become robust to uncontrollable noise variables. However, most previous Taguchi method applications have addressed a single-characteristic problem. Problems with multiple characteristics are more common in practice. The multi-criteria decision making(MCDM) problem is to select the optimal one among multiple alternatives by integrating a number of criteria that may conflict with each other. Representative MCDM methods include TOPSIS(Technique for Order of Preference by Similarity to Ideal Solution), GRA(Grey Relational Analysis), PCA(Principal Component Analysis), fuzzy logic system, and so on. Therefore, numerous approaches have been conducted to deal with the multi-characteristic design problem by combining original Taguchi method and MCDM methods. In the MCDM problem, multiple criteria generally have different measurement units, which means that there may be a large difference in the physical value of the criteria and ultimately makes it difficult to integrate the measurements for the criteria. Therefore, the normalization technique is usually utilized to convert different units of criteria into one identical unit. There are four normalization techniques commonly used in MCDM problems, including vector normalization, linear scale transformation( max-min, max, or sum). However, the normalization techniques have several shortcomings and do not adequately incorporate the practical matters. For example, if certain alternative has maximum value of data for certain criterion, this alternative is considered as the solution in original process. However, if the maximum value of data does not satisfy the required degree of fulfillment of designer or customer, the alternative may not be considered as the solution. To solve this problem, this paper employs the desirability function that has been proposed in our previous research. The desirability function uses upper limit and lower limit in normalization process. The threshold points for establishing upper or lower limits let us know what degree of fulfillment of designer or customer is. This paper proposes a new design optimization technique for multi-characteristic design problem by integrating the Taguchi method and our desirability functions. Finally, the proposed technique is able to obtain the optimal solution that is robust to multi-characteristic performances.

Reinforcement learning (RL) is widely applied to various engineering fields. Especially, RL has shown successful performance for control problems, such as vehicles, robotics, and active structural control system. However, little research on application of RL to optimal structural design has conducted to date. In this study, the possibility of application of RL to structural design of reinforced concrete (RC) beam was investigated. The example of RC beam structural design problem introduced in previous study was used for comparative study. Deep q-network (DQN) is a famous RL algorithm presenting good performance in the discrete action space and thus it was used in this study. The action of DQN agent is required to represent design variables of RC beam. However, the number of design variables of RC beam is too many to represent by the action of conventional DQN. To solve this problem, multi-agent DQN was used in this study. For more effective reinforcement learning process, DDQN (Double Q-Learning) that is an advanced version of a conventional DQN was employed. The multi-agent of DDQN was trained for optimal structural design of RC beam to satisfy American Concrete Institute (318) without any hand-labeled dataset. Five agents of DDQN provides actions for beam with, beam depth, main rebar size, number of main rebar, and shear stirrup size, respectively. Five agents of DDQN were trained for 10,000 episodes and the performance of the multi-agent of DDQN was evaluated with 100 test design cases. This study shows that the multi-agent DDQN algorithm can provide successfully structural design results of RC beam.

The purpose of this study is to understand the concept of zero-waste design and to apply Sophia Vyzoviti’s folding techniques to develop a zero-waste fashion design method that contributes to sustainable fashion design. In this study, we explore the method and characteristics of zero-waste fashion design based on the concept of folding described in Sophia Vyzoviti’s book on folding techniques. Using the autonomy of Sophia Vyzoviti’s folding technique, four changeable folding fashion designs were developed and produced, demonstrating zero-waste fashion design. The results were as follows. First, the development of fashion designs using Sophia Vyzoviti’s folding techniques enabled the development and production of free and creative zero-waste fashion designs that were three-dimensional, continuous, fluid, and full of potential. Second, the production of zero-waste patterns was further developed into a transformable fashion design that can be used with geometric patterns. These folding techniques produced a fashion design method that could transform one piece of clothing, demonstration the potential for maintenance of creativity using a zero-waste design based on these folding techniques. Third, the double-faced fabric, Neoprene, was chosen as an appropriate material as it emphasizes the depth of folding with application of two colors and its cotton/polyester blend that is suitable for folding.

현재 국내외적으로 다양한 강재 댐퍼의 형상에 대한 연구가 이뤄지고 있다. 강재 댐퍼는 제진장치 중 하나로 항복을 통해 지진에너지를 흡수 및 소산하여 본 구조물을 보호한다. 최근 적용되고 있는 면내 전단 변형에 의해 작동하는 댐퍼는 응력이 특정 부위에 집중되어 재료의 대부분이 본래의 역량을 발휘하지 못하는 한계가 있었다. 따라서, 본 연구에서는 이 한계를 극 복하고자 전역 최적화 기법 중 하나인 뻐꾸기 탐색을 적용해 최적 형상을 설계하였다. 탐색된 최적 형상을 토대로 수치해석과 실제 실험을 통한 성능검증을 수행했다. 최적 형상으로 설계된 댐퍼는 안정적인 이력거동을 보이고, 높은 에너지 소산능력을 확 보하는 것으로 나타났다. 본 연구에서는 전역 최적화 기법을 적용한 최적 설계 방법을 제시하고 그 결과를 검증함으로써, 다양한 형태의 공학적 문제 해결에 대한 적용 가능성을 제시하였다.

Electronic document communication based on a digital channel is becoming increasingly important with the advent of the paperless age. The electronic document based on PDF format does not provide a powerful customer experience for a mobile device user despite replacing a paper document by providing the content integrity and the independence of various devices and software. On the other hand, the electronic document based on HTML5 format has weakness in the content integrity as there is no HTML5 specification for the content integrity despite its enhanced customer experience such as a responsive web technology for a mobile device user. In this paper, we design the Document-HTML, which provides the content integrity and the powerful customer experience by declaring the HTML5 constraint rules and the extended tags to contain the digital signature based on PKI. We analyze the existing electronic document that has been used in the major financial enterprise to develop a sample. We also verify the Document-HTML by experimenting with the sample of HTML electronic communication documents and analyze the PKI equation. The Document-HTML document can be used as an authorized electronic document communication and provide a powerful customer experience in the mobile environment between an enterprise and a user in the future.

본 연구에서는 철골편심가새골조 시스템을 대상으로 다목적최적화기법을 통해 설계를 수행하고 그 결과를 분석하였다. 최적화 설 계를 위해 유전 알고리즘의 일종인 NSGA-II를 활용하였다. 여기서, 목적함수는 이율배반적 관계를 갖는 구조물량과 층간변위로 하여 최소화되고, 제약조건에는 구조기준에서 요구하는 내력비, 링크의 회전각 등을 포함하였다. 제약조건은 최적화 알고리즘 내에서 각 항목을 위반할수록 목적함수 값을 크게 증가시키는 벌금함수의 형태를 가지고 있다. 설계기준에서 EBF 시스템의 설계규정은 링크 부재만 항복이 허용되며 나머지 부재는 링크 항복 시 발생되는 부재력을 탄성상태에서 견디도록 의도한 역량설계법에 기초한다. 그러나 최적화를 통해 도출된 결과 중 일부는 구조기준의 설계조항은 만족하지만 특정층 링크에 소성변형이 집중되어 연약층을 형성함 으로써 기준에서 의도하는 역량설계의 원칙을 위배하는 결과가 나타났다. 이를 해결하기 위해 모든 링크의 전단 초과강도계수 중 최 대값이 최소값의 1.25배를 넘지 않도록 하는 제약식을 추가하였다. 새로운 제약식을 추가한 경우 모든 최적해는 설계기준과 역량설계의 원칙을 준수하는 것으로 나타났다. 모든 설계안에서 보 경간에 대한 링크의 길이비는 전단링크의 범주에 해당하는 10% ~ 14%였다. 전체적으로 설계안들은 링크의 초과강도 계수비가 가장 지배적인 제약으로 작용하였으며, 구조기준의 요구사항 중 층간변위와 내력비 등의 항목에서 허용치에 비해 매우 보수적으로 설계되었다.

Currently, the commercialization of the 5th Generation (5G) service is becoming more prevalent in domestic communication network technology. This has reduced communication delay time and enabled large-capacity data transmission and video streaming services in real-time. In order to keep pace with these developments, K-water has introduced a smart process control system in water purification plants to monitor the status of the water purification process. However, since wireless networks are based on the public Long Term Evolution (LTE) network, communication delay time remains high, and high-resolution video services are limited. This is because communication networks still have a closed structure due to expense and security issues. Therefore, with 5G in its current form, it is very difficult to accommodate future services without improving the infrastructure of its communication networks. In recognition of these problems, this study implemented the authentication and management function of wireless networks on a wired network management system in the K-water Bansong water purification plant. The results confirmed that wired Local Area Network (LAN) services give a higher security performance than an expensive commercial wireless LAN system. This was achieved by using an Internet Protocol (IP) address management system of wired networks and the packet filtering function of the Layer2 (L2) switch. This study also confirmed that it is possible to create a wireless LAN service that is 3.7 times faster than the existing LTE communication network.

This research was conducted to elucidate the optimum conditions for the antibacterial activity of konjak jelly using the evolutionary operation-factorial design technique. In the first set of experiments, concentration of a coagulation agent, soaking liquid, and temperature of water were set to 0.4%, 0.6×10－2 N, and 65℃ as a central point, respectively. The highest antibacterial activity was acquired at E21, in which the number of bacteria was 1.25 log cfu/g. Because the code of changes in the main effect was (-), it could be decided that the central point of the first set was not the optimum point. Although antibacterial activity in the second set was improved, the values of the main effect were higher than that of changes in the mean effect. The central point of third set was concentration of coagulation agent 0.8%, concentration of soaking liquid 1.0×10－2 N, and temperature of water 65℃. It was found that the antibacterial activity of central point in the third set was highest among all the tested set. Further, all the necessary conditions were appropriate to reach the optimum condition. The antibacterial activity of the central point in third set was more than 1,000 times higher than that of E11, in first set.

This study considers the modern expression of oriental esthetics by analyzing the fashion design with the Chinese ink technique based on the concept of Chi-Yun- Sheng-Tung, which was regarded as the best rule of art creation in oriental history. This study was performed by conducting a literature review of related books and advanced studies, and then, collection analysis was done with photos derived from fashion websites (seoulfashionweek.org, chinafashionweek.org, vogue.com, firstview. com) from 2010 S/S to 2016 S/S. A total of 317 fashion photos of designs created using the Chinese ink technique by Korean designers at Seoul Fashion Week and Chinese designers at China Fashion Week were analyzed. The contemporary fashions created with the Chinese ink technique were characterized by, first, the bold brush strokes and natural spreading effects of Chinese ink, second, the emphasis of empty space by taking essential elements, and third, the coexistence of deep Chinese ink colors with modern primary colors. The formativeness of the contemporary fashions created with Chinese ink technique based on Chi-Yun-Sheng-Tung were as follows: first, temperance, pursuing spiritual and minimal expression, second, empty space, making design elements interact and pursue harmony, third, changeable rhythm, symbolizing the growth and variation revealing the power of life, and fourth, vitality, represented in the rhythmical movement of the brush. This study was based on the oriental esthetics inherent in Chi-Yun-Sheng-Tung, and it attempted to analyze contemporary fashion design. The aim was to show the possibility of modern applications to traditional values, and it can be a meaningful case in design planning based on culture.

In the age of hybrid, the fashion industry has created multiple patterns of hybrid fashion due to mixed styles and genres. Fashion mixed with tradition and future and various cultures is emerging as a trend so that Asian cultures are reinterpreted in a modern way(Samsung Design Net. 2014). Korean images also change every year into a new type of cultural hybrid. This study aims to present esthetic and trendy hybrid outer wear designs applicable to the fusion of tradition and present and the west and the east as well as diverse life styles for the major target of consumption, the senior generation with young sense. This study conducted both theoretical and empirical study. The theoretical study looked into the characteristics of digital fashion illustrations using Sumuk technique and of senior outer wear through the precedent study and literature. In the empirical study, fashion illustrations were made according to the characteristics of digital fashion illustrations with Sumuk technique, and then fabric was made through digital printing. By doing so, hybrid outer wear designs for the senior generation were developed based on the characteristics of senior outer wear, and the real artwork was made. The findings are as follows. First, the characteristics of digital fashion illustrations using Sumuk technique are the hybrid expression where the spirit of inner feeling of oriental thinking, implications of symbolism and metaphor through blanks and lines, and fortuity of ink blurs and lines are recreated in a modern way through digital fashion illustration characteristics such as hybridity of multi-cultures and heterogeneous factors, expandability of blurring boundary, human-oriented playfulness, and sensibility of inner expression. Second, outer wear for the senior generation puts the most emphasis on aesthetic factors including designs, styles, youth, and complement of figure, followed by symbolism such as convenience of dressing or undressing, comfort, functionality of flexible size, trend, express of individuality, and dignity. In addition, this generation prefers outdoor wear for social, cultural, and casual activities and demand hybrid city wear designs adding the characteristics of outdoor wear that is highly worn for various city life styles. Third, the design motifs of fabric made by digital printing of Sumuk technique-based digital fashion illustrations include traditional ornaments of Joseon Dynasty such as norigae(Korean traditional ornaments worn by women), binyeo(Korean traditional ornamental hairpin), and ddeoljam(ornamental hairpin), mix traditional and Korean spirit with modern sensibility, and connote esthetic beauty of ornamental effects for women’s beauty and symbolism of lucky signs and wishes. Fourth, senior outer wear was designed using the made fabric. Work 1 arranged prints with the motif of traditional norigae in a spaced pattern. Hybrid outer was designed with comfortable, light, and reversible functions by using A line silhouette considering the senior generation’s figure, single buttons for easy clothing change, and outdoor wear materials and highlighted the utilization of city wear. Work 2 used border pattern of fashion illustration prints that use binyeo as its motif, and it was designed for social and cultural life styles with the fusion of tradition, which uses tent silhouette durumagi(traditional Korean outer coat) and composition lines that are plane and straight lines, and modernism. It highlighted functionality by using zippers and single buttons for each clothing changing and outdoor materials. Work 3 arranged fashion illustrations made by the motif of ddeoljam in a spaced pattern. This is a balloon silhouette considering the senior generation’s figure and a urban, modern design with unbalanced hem line with asymmetry of light and left. A zipper was attached, and a light and flexible outdoor material was used to emphasize its functionality. Work 1, 2, and 3 made the fabric of cultural hybrid sense using Sumuk technique-based digital fashion illustrations and used the design considering the senior generation’s figure and an outdoor material, and expressed easy clothing change and design of city wear. This is a hybrid senior fashion design expressing the fusion and coexistence of traditional and modern beauty, Korea’s oriental beauty and modern western beauty, and outdoor wear’s functionality and city life styles. This study will contribute to the invigoration of the senior fashion market that is newly emerging and the development of high-value added products as it presents hybrid outer wear adding functionality applicable to various life styles for the senior generation with the young sense.
