This paper aims to examine the status of sizing specifications for disposable sanitary pads on the market and to offer information on product design that reflect the requests of consumer by gathering opinion through the practical experience of consumers. Seventy-six varieties of sanitary pads on market are measured and the evaluations of wearing comfort were investigated by the questionnaire and interview for sixty three varieties of sanitary pads. As a result, they were classified into five sizes related with length but vaguely related with thickness and width. Thickness is distinguished by the compressibility that is marked as slim or ultra slim by the same brand. However, there is no sizing consistency for all products. The result shows that there is some confusion for consumers to choose desired sizes, In addition, the perception of wearing is categorized into four factors that are product performance, size and fit, wearing feeling and margin of action, and adhesive property and wrapping. The manufacturing specifications for the sanitary pads on domestic market, the requests of consumers for sanitary pad design modifications, and proposals for follow-up studies were figured out through this research.

The government has defined domestic violence as one of the four major social evils and tried to prepare laws and systems to prevent it. Nevertheless, domestic violence has emerged as a serious social issue, and compare to the number of domestic violence cases that are constantly increasing, the report rate of domestic violence is significantly lower. This suggests the need to improve citizens' perception of domestic violence as the issue to solve it together in society, not as a private matter at home. Most of existing contents for preventing domestic violence and improving awareness are simple viewing forms of video contents, which have little effect on recognition. We aim to confirm the possibility of improving social awareness about domestic violence by producing Virtual Reality (VR) contents that have great features of user's immersion and empathy. In this VR content, the user can interact with various objects in the virtual reality of domestic violence and directly or indirectly experience the victim's position. Users who view the violent environment from the victim's point of view can have a subjective empathy for the problem, which is expected to induce more active awareness about domestic violence.

This study aimed to investigate the impact of pavement design changes on user perceptions, with the objective of enhancing safety in urban streetscape. A total of 72 participants were recruited, and the study focused on alleyways in areas with a high risk of crime. Employing the Semantic Differential (SD) methodology, an assessment was conducted to gauge participants' perceptions of three different pavement types (A-type, B-type, C-type) as well as the existing pavement. The results indicated that the C-type pavement, characterized by vibrant and harmonious color palettes and patterns, elicited the highest levels of perceived safety, comfort, and openness among users. This signifies that physical environmental improvements through color design can mitigate the feelings of insecurity and foster emotional stability. Therefore it is recommended to implement various color schemes and pattern designs to road surface for enhancing user safety in high-risk urban areas.

Laundry has traditionally been regarded as one of the most demanding household chores, but the introduction of smart washing machines is changing this perception. Although smart washing machines have been on the market for several years and consumers' perceptions of washing machines have changed, little is known about consumers' perceptions of smart washing machines. The purpose of this study is to determine what users expect from smart washing machines. We conducted two focus group interviews with sixteen participants who had used smart home appliances to acquire qualitative data. Stimuli created by the interviewees were applied in the focus group interviews to collect more insightful data. We analyzed the data using the three-step method and QSR NVivo. Analysis revealed ten categories of predictive expectations, including seven utilitarian attributes (i.e., smart functionality, smart user interface, reliability, controllability, interactivity, functional value, and economic value) and three hedonic attributes (i.e., fashionable value, psychological value, and social value). The results of this study have implications for the development of smart washing machines that would satisfy consumers by taking user expectations into account.

Today many owners of Web sites are looking to user's satisfaction survey as a key means of measuring the usability of a Web site. While it is preferred for it simplicity and ease of use, this survey method is not without potential risks. This paper focuses on showing that the existing practice of questionnaire-based usability measurement is subject to human recall errors, and that such flaws can be reduced when the questionnaire survey is followed by the users hands-on experience of the site. An empirical study was conducted, and the results indicate that the above speculation holds true. Even if respondents felt highly confident about their responses on a recall survey, a hands-on experience with a focal Web site increased the extent to which the respondents were satisfied with the shopping mall site. This indicates that a user's perception of the quality of a Web site may be distorted or lost as time goes by. In addition, the findings have shown that the use of the verbal protocol analysis method can reveal critical information that can help track the root causes of Web site usability problems, thereby helping to develop site enhancement strategies. The paper concludes with directions for future research.

최근 플로팅 방식의 홀로그램이 전시, 교육, 광고 등에 많이 활용되고 있다. 그중에 하프 미러 방식은 플로팅 홀로그램 중 가장 널리 쓰이는 방식 중 하나이다. 하지만 하프 미러 방식은 완벽한 3차원 홀로그램의 경험을 주지는 못한다. 이미지가 공중에 떠 있는 것처럼 보이기는 하나, 홀로그램의 궁극적 목표인 공간상에 가상 이미지를 표현하지는 못한다. 더욱이 하프 미러 후면에 실제 오브젝트를 두고 가상의 이미지와 결합하여 함께 보여주고자 할 때, 두 객체가 공간상에서 불일치되는 현상이 발생한다. 본 논문에서는 스테레오 증강현실 홀로그래피에서의 삼차원 공간감 비교를 위한 연구를 진행하였다. 3차원 공간에서의 정확하고 효율적인 증강현실 구현을 위하여 하프 미러 기반 홀로그래픽 시스템에 입체 영상기법을 적용하였다. 이는 하프 미러 필름 후면에 위치한 실제 오브젝트와 하프 미러를 통해 반사된 가상 이미지가 같은 공간상에 함께 어우러져 있는 것처럼 표현할 수 있다. 또한, 뎁스 카메라를 사용하여 사용자의 움직임에 맞게 가상 카메라를 조절함으로써 자연스러운 패러럭스 표현이 가능하도록 하였다. 본 연구에서 제안하는 방법은 별도의 추가 장치 없이, 단지 하프 미러 필름을 통해서 비교적 간단하고 정확하게 실제 객체의 위치와 같은 공간상에 증강된 시각 정보를 표현한다. 제안한 증강현실 홀로그래피에서의 삼차원 공간감에 대해 비교 실험을 한 결과, 2D 이미지를 적용한 경우 보다 3D 이미지 혹은, 3D 이미지와 사용자 인터랙션을 함께 적용한 경우, 사용자에게 3차원 공간감, 현실감(realism)을 더 정확하고 효과적으로 제공할 수 있음을 확인하였다.
