The underground method can be divided into Top-Down, Semi-Top-Down, Up-Up and Down-Up methods according to the construction order of the upper and lower structures. Among them, the Down-Up method proceeds with the construction of the first floor and its lower floors, and when the foundation is completed, the vertical members of the basement are sequentially completed from the foundation and the above-ground floor is constructed. In this paper, the crack reduction method around the open section of the Down-Up method affected by earth pressure was analyzed and divided into design and construction parts.

Tilt-up construction is the method that the wall structures are fabricated horizontally on site and placed at specified location using heavy lifting equipment. Tilt-up method generally has several advantages, such as of productivity improvement, labor savings, shortened the construction period the and cost savings. In this study, Tilt-up method is used for wall construction of detached house. Result shores the substantial improvement on construction period. The use of Tilt-up method led construction period reduction of 20%.

Glass wool filtration and swim-up method resulted in inreasing to 58.3% and 62.7% of the progressive motility in frozen-thawed boar sperm, compared to 34.2% in the untreated sperm. Glass wool filtration tended to be more successful than swim-up method for the survival sfter incubation of 38.5$^{\circ}C$ for 3h. Sperm recovered by both the swim-up method and the glass wool filtration method were tested in an in vitro fertilization to determine which of the two techniques would yield sperm with high fertilizing capacity. The results indicated that there was a significantly(p

Fashion is the second most polluting industry. We must strive to transition to a form of industry that does not cause environmental pollution. These efforts drive may fashion brands to produce and sell products with redesigned methods that delight the inventory flow. Accordingly, it is necessary to develop creative apparel up-cycling design using the creative thinking method. This study aims to produce clothing redesign works by introducing design idea types for systematic redesign creation. In this research, we conducted a literature review on the concept of up-cycling design and employed heterotopa spacial concept reflected fashion design creation methodology types. The RE;CODE, a leading domestic up-cycling design brand, was used in case analysis. According to the command of shape transformation, it is spreading, stacking, dropping, inverting and crossing, from the creative thinking method reflecting heterotopia spacial concepts, showing designers a concrete way to transform form into new apparel. Seven works of apparel up-cycling design were developed by conducting process of RE;CODE. Also, to establish an apparel up-cycling design creation process for creating works. In this study, we proposed a systematic method for apparel up-cycling design, including a method for reorganizing two or more different materials to create something new and ultimately reversing the structure. The value and significance of this study is that it proposes a systematic method for apparel up-cycling design to make it new.

The purpose of this study is to investigate the visual elements for effectively conveying the make-up method of the Korean history. We will do basic research on language visualization through visual poetry by using a make-up method as a visual expression element. Our research methods consisted of a related literature research, an internet search, and case study methods. The make-up methods of Korean classical make-up through visual poetry consisted of a through literature review. First, make-up methods, cosmetics, jewelry, and hair styles are shown in the classic make-up style of each age. Second, classical make-up visual poetry shows the identity, gender, and character depictions. Third, there were many visual metaphors about the hair types, figures, and hair among the classical make-up methods of each age. I think that this topic is worth researching as an appropriate medium to increase attractiveness. This research is with visual expression elements of the Korea make-up method. This study analyzed the Korean traditional make-up method that expresses and reinterprets visual metaphors. The results of this study can be applied for basic research.

In this paper, we propose an optimum design method for optical pick-up actuators. Using this method, we can design an optimal pick-up actuator having the required tracking/focusing performances. Also, the designed actuator has the small mass, force constant for small size of magnetic circuit and large resistance for reduction of heat generation. Simulation results show that this method can be potentially implemented in all the pick-up actuators.

재난방송의 효과를 높이기 위해서는 수신기에 자동인지(wake-up) 기능이 반드시 포함되어야 한다. 자동인지란 단말이 항상 재난여부를 확인하고 재난이 확인되면 단말이 활성화되어 즉시 사용자에게 재난정보를 알리는 기능이다. 법에 지정된 재난방송 매체 중 하나인 지상파 DMB는 표준에서 이 기능을 기술적으로 구현할 수 있도록 되어 있으나 배터리 효율 등의 문제로 실제 자동인지 기능을 가진 단말은 출시되지 않고 있다. 본 논문에서는 자동인지 문제를 해결하기 위한 방안으로 T-DMB 수신 기능을 가진 안드로이드 스마트폰 환경에서 구글 C2DM을 이용하였다. 이 방법을 이용하여 재난시 단말을 깨우고(wake-up), 사용자의 선택에 따라 T-DMB를 통해 추가적인 멀티미디어 재난정보를 확인할 수 있다.

액정 구동 IC에서 발생하는 기생 p-n-p-n 회로의 래치업 문제를 개선하기 위해 power-up 순서상에 순차 스위치를 삽입하는 방법을 제안하였다. 제안된 순차 스위치는 2차-승압회로와 3차-승압회로 내에 삽입되며, power-up 순서상에서 해당 승압회로가 동작하기 전에 기생 p-n-p-n 회로의 분리된 에미터-베이스 단자를 순차적으로 연결하게 된다. 제안된 구조의 성능을 검증하기 위해 0.13-um CMOS 공정을 이용하여 테스트 IC를 설계 제작하였다 측정 결과, 기존의 경우 $50^{\circ}C$에서 액정 구동 전압이 VSS로 수렴하면서 과전류를 동반하며 래치업 모드로 진입하였으나, 제안 회로를 삽입한 경우는 고온($100^{\circ}C$)에서도 정상 전류 0.9mA와 정상 액정 구동 전압을 나타내어 래치업이 방지되고 있음을 확인하였다.

Purpose: With the development of digital dental technology, we are manufacturing prosthetic crown in various ways. However, the wax-up method that makes existing prosthetic crown is also used steadily. Thus, we will compare the shape of the crown designed with wax-up and the crown designed with CAD. Methods: Sculpt the crown with wax-up on the model to 10 dental technicians. The same model was used to design the crown CAD. Measure the size of the sculpted crown. The shapes were compared in three dimensions. Results: As a result, we could observe a difference in size and shape in crown designed with wax - up crown and crown. Conclusion: These results suggest that there are differences according to the method of carving crown and the method of processing.

This paper describes research results for the measurement and analysis method of magnetic signatures generated from the ship's magnetic mock-up model. In this paper, we present the theoretical and experimental techniques for the separation of the permanent and the induced magnetic field from the measured magnetic signature of the mock-up model. Also, we describe the prediction method of the induced magnetic field generated from mock-up model using the Magnet s/w, one of the FEM analysis tools for the electro-magnetic field and the magnetic dipole modelling method based on the least square techniques. The proposed modelling and analysis methods can be used for the prediction and the analysis of the static magnetic field generated from the real naval ship as well as the mock-up model.
