The purpose of this study is to evaluate by experiments and 3-D finite element predictions of strain-hardening cementitious composite(SHCC) structural walls. The specimen of concrete wall used shear reinforcements to satisfy with design shear strength, while the specimen of a SHCC wall used minimum shear reinforcement. The finite element prediction is based on the total strain crack model, and appropriate tensile models were applied according to the material characteristics of concrete and SHCC. The accuracy of the finite element prediction was verified by comparison with experimental results, and the SHCC wall showed superior structural performances in overall load-carrying capacity as well as in reductions of damages caused by crack localizations, even with minimum use of shear reinforcements.

이 연구의 목적은 감성 마케팅의 대표적 성공사례로 손꼽히는 스타벅스 배경음악의 음악적 특징 을 분석하여 고객에게 긍정적 영향을 주는 음악적 요소들을 밝혀내고, 기존 연구와의 차이점을 통해 배경음악의 트렌드 변화를 알아보는 것에 있다. 분석을 위해 연구자는 스타벅스 매장을 방문 하여 표본으로 사용할 91곡의 음악을 수집하였고, 선행연구를 기반으로 배경음악 분석에 필요하 다고 여겨지는 조성, 템포, 장르, 악기 구성, 가사 유무, 발매연도 등의 음악적 요소를 분석항목 으로 설정하였다. 각 항목의 분석 결과 스타벅스의 플레이리스트는 모호한 조성과 중간 템포 이상 의 빠르기를 가진 최신 팝 음악 그리고 가사가 있는 음악들의 비율이 높았다. 이러한 결과는 장조, 느린 템포, 가사가 없는 음악과 같이 고객에게 긍정적 영향을 미친다고 알려져 있는 기존 배경음 악의 이론과 배치된다. 또한 올드 팝, 오래된 재즈 음악을 주로 사용한다는 과거의 스타벅스 배경 음악에 관한 선행연구와도 차이가 있다. 따라서 스타벅스 매장 음악에 변화가 있었음을 알 수 있 었으며, 이는 세대교체에 따른 고객의 매장 방문목적, 연령대, 음악적 취향 등을 반영한 것으로 판단된다. 본 연구는 다양한 음악적 요소들을 통해 스타벅스 배경음악의 특징을 구체적으로 분석 하고, 이를 토대로 배경음악의 트렌드 변화를 살펴본 첫 시도임에 그 의미가 있다. 또한 분석에 사용된 음악적 요소들은 배경음악 연구의 새로운 이론적 기준을 제시할 것이다.

Nacre of abalone shell features a “brick-and-mortar” microstructure, in which micro-plates of calcium carbonate are bonded by nanometers-thick layers of chitin and proteins. Due to the microstructure and its unique toughening mechanisms, nacre possesses an excellent combination of specific strength, stiffness and toughness. This study deals with the possibility of using nacre fragments obtained from abalone shell for making a bulletproof armor system. A composite plate laminated with abalone shell fragments is made and compression and bend tests are carried out. In addition, a bulletproof test is performed with hybrid armor systems which are composed of an alumina plate, a composite plate, and aramid woven fabric to verify the ballistic performance of nacre. The compressive strength of the composite plate is around 258.3MPa. The bend strength and modulus of the composite plate decrease according to the plate thickness and are about 149.2MPa and 50.3 GPa, respectively, for a 4.85 mm thick plate. The hybrid armor system with a planar density of 45.2 kg/m2, which is composed of an 8 mm thick alumina plate, a 2.4 mm thick composite plate, and 18 layers of aramid woven fabric, satisfy the NIJ Standard 0101.06 : 2008 Armor Type IV. These results show that a composite plate laminated with abalone shell fragments can be used for a bulletproof armor system as an interlayer between ceramic and fabric to decrease the armor system’s weight.

Semiconductor manufacturing has suffered from the complex process behavior of the technology oriented control in the production line. While the technological processes are in charge of the quality and the yield of the product, the operational management is also critical for the productivity of the manufacturing line. The fabrication line in the semiconductor manufacturing is considered as the most complex part because of various kinds of the equipment, re-entrant process routing and various product devices. The efficiency and the productivity of the fabrication line may give a significant impact on the subsequent processes such as the probe line, the assembly line and final test line. In the management of the re-entrant process such as semiconductor fabrication, it is important to keep balanced fabrication line. The Performance measures in the fabrication line are throughput, cycle time, inventory, shortage, etc. In the fabrication, throughput and cycle time are the conflicting performance measures. It is very difficult to achieve two conflicting goal simultaneously in the manufacturing line. The capacity of equipment is important factor in the production planning and scheduling. The production planning consideration of capacity can make the scheduling more realistic. In this paper, an input and scheduling rule are to achieve the balanced operation in semiconductor fabrication line through equipment capacity and workload are proposed and evaluated. New backward projection and scheduling rule consideration of facility capacity are suggested. Scheduling wafers on the appropriate facilities are controlled by available capacity, which are determined by the workload in terms of the meet the production target.

Kim, Jung-woo. 2006. A Study on the Aspects of Expression of Identity in E-mail IDs. The Sociolinguistic Journal of Korea, 14(1). The aim of this study is to uncover the characteristics of expression of identity in e-mail identification (ID). At the present, people live in two societies. One is the real society and the other is virtual society. To live in each society, people must have their own unique identity. A person's identity in real society is ascribed by his/her social status. However, in virtual society, one can create an identity in his/her individual way. Name and e-mail ID are very effective ways to distinguish one from others in each society. Therefore, in this study, the ways of creating an e-mail ID are researched and nine aspects of making an identity by using language is examined. As a result of this research, it is concluded that an e-mail ID has distinctive characteristics that a family name does not, which stem from spontaneity and creativity.

The purpose of this study is to examine the changing trends of language usage in radio advertisements. Radio has made efforts to compete with other mass media. This study proposes to divide the changing trends of radio advertisements into five periods according to competing relationships between radio and the other media. Diverse aspects of language usage were found in each period; they relate to the radio's efforts to solidify its position against other competing media such as newspaper and television. This paper suggests, in conclusion, that the trends of language usage in radio advertisements have reflected the radio's efforts to fortify its communication efficiency in communicating to the masses.

한반도 동해에서 Topex/Poseidon위성 고도레이더로부터 관측된 해수면과 울릉도, 포항, 속초의 조위계에서 관측된 해수면을 비교하여 두 자료의 연계성을 분석하고 위성에서 관측된 해수면자료의 객관성을 검증하였다. 1992년부터 1997년 사이에 관측된 T/P MGDR 관측자료로부터 해수면을 추출하기 위하여 대기보정 및 지구물리학적인 보정을 실시하였다. 조위계로부터 관측된 해수면과의 비교를 위해 조위관측소로부터 반경 약 55km내에 위치하는 관측값들을 평균하였다. 위성 해수면과 조위계 해수면을 비교한 결과 내해역에 위치한 포항 및 속초가 외해역에 위치한 울릉도에비해서 낮은 연관성을 보였다. 200일을 기준으로 저역통과필터를 처리했을 때 외해역에 위치한 울릉도는 상관값이 0.91로 매우 높은 유의성을 보였고, 내해역에 위치한 포항 및 속초는 각각 0.58 및 0.65로서 울릉도에 비해서 상대적으로 낮은 유의성을 보였다. 이러한 큰 차이는 M2, S2, K1 분조 등에 의한 조석변형 때문에 발생하는 현상으로 볼 수 있고, 이는 주로 T/P 자료처리에 사용된 조석모델의 오차로 볼 수 있고, 이를 저역통과필터를 적용하여 효과적으로 제거하였다. 대체로 외해역의 경우는 60, 120, 180, 200일의 필터를 순차적으로 처리함에 따라 상호 두 자료간의 유의성이 점차적으로 개선되는 것을 확인할 수 있었으나 내해역의 경우에는 거의 유의성이 개선되지 않는 것으로 확인되었다.
