최근 전기자동차와 관련된 콘텐츠 연구에서 사운드 디자인이 새로운 연구 주제로 부각되고 있다. 이 연구는 전기자동차 실내 주행음 디자인의 주요 가치들을 사용자 경험(User Experience) 측면에서 탐색하고 검증하는 것을 목적으로 진행되었다. 근거이론에 의한 탐색적 연구를 통해 맥락정보성과 정숙성을 독립변수로 도출하여 $2{\times}2$ 요인 설계로 유용성, 감성, 만족도에 대한 주효과 및 두 변인 간 상호작용 효과를 분석하였다. 실험연구를 통해 맥락정보성과 정숙성의 조합에 따라 전기 자동차의 사용자 경험에 미치는 영향이 달라진다는 점을 밝혔다. 연구 결과에 기반하여 실내 주행 사운드 가치의 개인별 선호를 고려한 사용자 니즈 최적화를 위한 후속 연구 방향을 제시하였다.

본 연구는 전기차를 렌트한 이용자의 만족도가 전기차 구매에 어떠한 영향을 미치는지에 대한 검증을 목적으로 한다. 연구 결과, 전기 렌터카 이용 후 만족도와 유의미한 상관관계를 가지는 요인으로 성별, 연령, 정숙성 및 승차감, 충전 인프라가 확인되었으며, 연령, 정숙성 및 승차감, 충전 인프라 요인은 전기 렌터카 이용 후 만족도를 통해 전기차 구매 관심 및 의도에 영향력을 미치는 것을 확인할 수 있었다. 연구의 차별성은 전기차 체험을 통한 전기차 보급 견인의 주요 수단으로서 전기 렌터카에 초점을 맞추어 실증연구를 통해 분석했다는 측면과 전기 렌터카를 통해 전기차를 처음 경험한 이용자들을 분석 대상으로 한정했다는 측면을 들 수 있다.

Recently, With the increase of income level, many people desire to have agreeable and quiet surrounding. However, the extent and time of the exposure to construction noise and vibration is increasing, which is a factor that ruins the quietness of the surrounding and increasingly raises interests in its effects. In this point, this study attempts to survey the characteristics of construction vibration by SD(Sand drain) method in construction field. In addition, the result of study is presumed to be usable as the fundamental materials for an efficient counter-plan in case of the public resentment in relations to the construction vibration occurring henceforth.

The purpose of this study was to identify structural patterns in the subjectivity of Taegyo in pregnant woman and to provide a basis for nursing interventions. Thirty pregrant women were the subjects of this study. They were in the gestation period of pregnancy between 12 weeks to five days post partum and they lived in the city of Taejon. The research method employed Q-methodology which is based on self-psychology and abductive logics. The results revealed three different types of the Taegyo ; 1) Peaceful mind type, listening to music and appreciation of art for quietness of mind and also the support and concern of husband. 2) Self control type, recognizes herself as a pregrant woman and trys to do her works spontaneously and also adapt herself to changing of circumstances. 3) Dependent oriented type, needs absolute help from the surroundings under the specific condition of pregnancy. This results show that investigating the specific experience, characteristic and structure of the Taegyo of a pregnant woman can be used as a part of the nursing assessment and also provides useful basic data of nursing interventions during pregnancy.

This study aimed to investigate the relationship between ideal images of women and women's clothing fashion England between 1820s and 1850s. The age was divided into two periods, which were 1820-1836 and 1837-1850. During the first period, the ideal images of women were those of fairy, spirit, and angels, which were expressed by tight waist belt, wider and shorter skirt, top expanded sleeve, wide and flat pelerine collar, feather decoration, elaborate and curly hair style, narrow and light ballerina shoes etc.. During the second period, the ideal images for women were those of lady with modesty, quietness, and weakness. They were expressed by long and full skirt, tight or bulge over the lower arm sleeve, dropped sleeve, poke bonnet, body wrapping large shawl and sober color etc.. The result shows that the ideal images of women in 19th century England were concretely expressed by various clothing fashion including hair style, shoes, and decoration. This study sheds light on psychological, historical, and theoretical approaches to clothing.

The method of promoing sound surroundings with the new concept named 'Soundscape' attracts the public attention. This new method is the way of active promoting acoustic surroundings to offer the vitality, comfort and identity of urban space and relative quietness by masking the noise with natural and signal sounds. Therefore, this research has the purpose of finding out the method of soundscape concept of urban public space for the comfort acoustic surroundings.

Pleasantness or quietness becomes one of the most important factors for residential designs recently. Especially for apartments, the noise generated by falling objects becomes a sensitive issue these days. To overcome the problem of the impact noise in apartments, the floor design has been changed. To reduce the transmissibility of the noise, composite floor structures are devised and implemented for the construction of apartments. In this paper, the noise reduction performance of a composite floor plate with holes is analyzed. Computational modelings for the structures are developed and its performance is evaluated by using the finite element method. The results show that the noise can be well reduced with the multi-layer composite floor plates with holes.

The comfort and quietness of vehicle has been improved greatly due to the development of technology in automobile industry. It is driven by reduction on the level of vibration and noise in powertrain system. However, the hidden problems in automobile parts become noticeable since the vehicle has been better in overall performance. One of them is related to the fuel pump system. Therefore, this study is focused on investigating the characteristics of fuel pump and fuel tank first, and then comparing the data before and after installation of fuel pump system in a testing vehicle. Additionally, the measured data will be analyzed to identify the problems and find a solution to improve the level of noise and vibration in fuel pump system.

More than 100 γ−ray pulsars have been discovered by the Fermi Gamma-ray Space Telescope. With a significantly enlarged sample size, it is possible to compare the properties of different classes. Radio-quiet (RQ) γ−ray pulsars form a distinct population, and various studies have shown that the properties of the RQ population can be intrinsically different from those of radio-loud (RL) pulsars. Utilizing these differences, it is possible to further classify the pulsar-like unidentified γ−ray sources into sub-groups. In this study, we suggest the possibility of distinguishing RQ/RL pulsars by their spectral shape. We compute the probabilities of a pulsar to be RQ or RL for a given spectral curvature. This can provide a key to the estimation of the intrinsic fraction of radio-quietness in the γ−ray pulsar population, which can place a tight constraint on the emission geometry.

The comfort and quietness of vehicle has been improved greatly due to the development of technology in automobile industry. Some of noise reductions, for example, are driven by the improvement in the power-train system. Due to better in all performance, it is required to reduce more noise in automobile components. One of them is related to the fuel pump system including a pump and a tank. Therefore, this study is focused on investigating the characteristics of fuel pump and fuel tank first, and then comparing the data before and after installation of fuel pump system in a testing vehicle. Additionally, the measured data will be analyzed to identify the problems and provide knowledge to reduce the level of noise and vibration in fuel pump system.
