The aim of this study is to develop new wedding dress designs by blending the traditional female Korean upper garment of Han-bok, known as dang-ui, with Western-style wedding dress designs. For this research, the author considered the various types of wedding dresses and their historical development based on literary resources and previous studies of the subject. The results are as follows: first, this study featured the use of different types of fabric for the dang-ui, selected from the various fabrics available for wedding dresses. Starting from the basic design of a sleeveless and strapless princess-line tight top, three different styles of A-line dresses were created: a tiered long dress, an unbalanced tiered midi dress, and a spangled and pleated mini dress. The study also resulted in a tight H-line mini dress with a bustle. In this way, the author was able to suggest new wedding dress styles that are well suited to the cultural trend of the Korean wave. Second, the traditional Korean dang-ui is an elegant ceremonial garment that harmonizes well with Western-style wedding dresses. Satisfaction can be found from combining these creative fusion gowns with traditional Korean aesthetics. Third, the traditional Korean ceremonial coronet jokduri and veil, which go well with dang-ui wedding dresses, are suitable accessories for contemporary wedding dresses. The dang-ui wedding dress, a result of merging the Korean dang-ui and the Western style, will help enhance business for both the Korean and the international wedding industry thanks to an aesthetic that has global appeal.

In this theoretical study, a design and performance analysis theory of a micro flowrate and high pressure air-compressor is developed. The governing equations are from the gas state equation and fluid dynamic theories because the working fluid in the air compressor is in a gas phase. A case study was conducted to design a reciprocating type of air compressor which the target performance was 0.6liter/min in the volume flowrate with 5atg in air pressure at 1,600rpm rotational speed. Geometrical size of the model air compressor designed is 10mm in stroke, 20mm in bore with 4.79 compression ratio. From the performance analysis of the model compressor, it was found that the air volume flowrate produced was 0.6liter/min with 5.81atg in pressure. The design theory of a micro-size high-pressure air compressor developed in this study is expected to be very useful design tools in NANO technology industry.

The design and analysis of the rigidity and deformation of the vehicle body are basically performed in two forms. First, the relative response of components separated from a parent system or connected as a model of a subsystem is examined. Second, the entire model is used to consider the absolute response of the components to the externally transmitted vehicle service load, which is defined as that of the entire vehicle body system. In this paper, we propose the finite element modeling for the structural design of the car body. First, we will explain the simple finite element modeling of the car body, explain the method of formulating the stiffness of the joint, and finally the shell element. The proposed finite element modeling is proposed. By applying the proposal, it is possible to propose finite element modeling of all medium and large passenger cars less than 3 tons.

Robot manipulators are highly nonlinear system with multi-inputs multi-outputs, and various control methods for the robot manipulators have been developed to acquire good trajectory tracking performance and improve the system stability lately. The computed torque controller has nonlinear feedforward control elements and so it is very effective to control robot manipulators. If the control gains of the computed torque controller is adjusted according the payload, then more precise control performance is attained. This paper extends the conventional computed torque controller in the joint space to the Cartesian space, and optimize the control gains for some specified payloads in both joint and Cartesian spaces using genetic algorithms. Also a neural network is employed to have proper control gains for arbitrary payloads using generalization properties of the neural network. Computer simulation results show that the proposed control system for robot manipulators has excellent performance in various conditions.

백두산에서는 밀레니엄 대분화 이후로도 수차례의 화산활동이 계속되어 마그마 거동 감시 연구의 필요성이 지속적으로 제기되고 있다. 마그마방의 깊이 및 규모를 파악하기 위해서는 다양한 지구물리학적 접근이 필요하며, 본 연구에서는 전기비저항 탐사의 적용성을 검토하고자 한다. 국경으로 인해 공간적 제한이 있는 백두산에서 심부에 위치한 마그마를 탐사하기 위해서는 측선의 길이가 수십 킬로미터 이상이 되는 대규모 전기탐사가 이루어져야 하며, 이를 위해 서는 분산계측 시스템의 도입과 이에 최적화된 탐사 설계가 필수적으로 요구된다. 따라서 자체 개발된 분산계측 시스템을 활용하는 탐사설계안을 제시하고 전산실험을 통해 적용 가능성을 분석하였다. 단일 측선과 비동일선상 송신원 배열을 사용한 탐사설계안을 이용하여 다수의 측선 설치가 필요한 일반적인 3차원 탐사에 준하는 역산 해석 결과를 얻을 수 있음을 확인하였으며, 이 탐사설계안이 백두산 심부 물리탐사에 유용하게 적용될 수 있을 것으로 기대된다.

PURPOSES : In Korea, asphalt overlay has been used as a typical alternative rehabilitation method for deteriorated pavements. However, asphalt overlay has problems due to poor bonding of the asphalt overlay and the old concrete. Recently, concrete overlays, which have advantages such as long-term durability and high structural capacity to carry heavy traffic, have been considered for rehabilitation construction. However, concrete overlays have limitations such as difficulty in opening to traffic and pavement noise. Recently, an appropriate fine-size exposed aggregate concrete pavement technique was reported to solve these problems. Therefore, this study aims to suggest an optimum mixture design of fine-size exposed aggregate concrete overlay (EACO) that can ensure low noise and early strength. METHODS : The optimum mixture design of fine-size EACO is determined to ensure adequate structural performance for early traffic opening and good functional performances such as low noise. Therefore, the optimum mixture proportion is determined based on the optimum design of aggregate content to produce a low-noise pavement texture by controlling the exposed aggregate number (EAN) and mean texture depth (MTD). RESULTS : The water-cement ratio and unit cement ratio were used to determine the mixture designs to achieve workability and adequate strength for early traffic opening. The texture was determined by selecting the maximum size of coarse aggregate smaller than 10 mm with an S/a ratio of less than 30% for low noise. With these mixture proportions, the EAN and MTD were 50±5 / 25cm2 and 1.0±0.2 mm. Respectively, which meet the criteria for EACO. CONCLUSIONS: In this study, an optimum mixture design of EACO for early traffic opening and low noise is suggested by using earlyhigh strength cement, and the pavement texture is implemented considering EAN and MTD. In addition, a pavement surface texture criterion is suggested for the quality control of EACO.

The purposes of this study are first to identify the core competences of design leadership and second to propose the characteristic and effective leadership capabilities required in the design field. To propose the capabilities of reliable and meaningful core competency of design leadership, we identified core competencies through a group of experts from the top group of design leaders (Design executives, head of the design institute) rather than using a survey study based on unspecified designers. In addition, the unique interview method, AI (Appreciated Inquiry) was also used to share the actual experiences and philosophies of the interviewers, regardless of the core competencies. This study revealed that the core competences of design leadership were different from those of conventional general leadership and MOT (Management of Technology) leadership capabilities. Besides, it provided opportunities for leaders in other fields to understand and collaborate on characteristics of the design field, while demonstrating the necessity and justification of unique leadership traits in the field of design.

A wireless sensor network is emerging technology and intelligent wireless communication paradigm that is dynamically aware of its surrounding environment. It is also able to respond to it in order to achieve reliable and efficient communication. The dynamical cognition capability and environmental adaptability rely on organizing dynamical networks effectively. However, optimally clustering the cognitive wireless sensor networks is an NP-complete problem. The objective of this paper is to develop an optimal sensor network design for maximizing the performance. This proposed Ranking Artificial Bee Colony (RABC) is developed based on Artificial Bee Colony (ABC) with ranking strategy. The ranking strategy can make the much better solutions by combining the best solutions so far and add these solutions in the solution population when applying ABC. RABC is designed to adapt to topological changes to any network graph in a time. We can minimize the total energy dissipation of sensors to prolong the lifetime of a network to balance the energy consumption of all nodes with robust optimal solution. Simulation results show that the performance of our proposed RABC is better than those of previous methods (LEACH, LEACH-C, and etc.) in wireless sensor networks. Our proposed method is the best for the 100 node-network example when the Sink node is centrally located.
