It has been common since ancient times to use fashion accessories to make a positive impression on others and develop personal brands. For this manuscript, I've designed a range of personalized electronic sounds and perfume accessories that use personalized scents and sounds to create memorable experiences. These have built-in auditory and olfactory actuators that can generate unique sound and fragrance signatures from the wearer and the other party. Based on the design explorations, I also discussed the issues of design and implementation of personalized electronic sound and fragrance accessories, as well as issues and additional business opportunities for the use of these personalized electronic sound and odor accessories in everyday life.

본 연구에서는 시각장애인이 시각 외의 잔존감각인 촉각, 청각, 후각을 활용하여 미술 작품을 감상하고 이해할 수 있도록 도울 수 있는 다중감각 인터랙션 기술을 제안한다. 나아가, 다중감각 인터랙션의 설계 적합성을 평가하기 위해 실제 시각장애인을 대상으로 다중감각 인터랙션 기술이 적용된 시스템을 통해 미술 작품을 감상한 경험에 대한 질적 인터뷰 기반의 사용자 테스트를 수행하였다. 사용자 테스트 결과, 미술 작품에 적용한 다중감각 인터랙션 요소들은 전반적으로 시각장애인으로 하여금 미술 작품 감상 및 이해를 도왔으며, 나아가 다중감각 인터랙션을 통해 미술 작품을 감상한 경험이 만족스러웠다는 긍정적인 평가 결과가 나타났다. 반면, 일부 다중감각 인터랙션 요소는 미술 작품을 감상하는 동안 전혀 인지하지 못하였거나 오히려 미술 작품 감상에 있어서 혼란을 야기했다는 부정적인 평가 결과도 나타났다. 본 연구는 시각장애인의 문화예술 작품 감상의 접근성을 증진할 수 있는 기술적 대안으로서 비시각 다중감각 인터랙션의 구체적인 개발 방향성 및 가이드라인을 제공하는 데 기여하였다. 나아가, 시각장애인뿐만 아니라 아동이나 노인과 같은 비시각장애인도 유니버설 인터랙션 기술을 통해 기존의 시각 위주의 단편적 경험을 넘어선 종합적인 감각적 경험을 할 수 있는 기술 기반을 구축하는데 기여할 수 있을 것으로 기대된다.

의료 분야는 가상현실 (VR, Virtual Reality)의 주요한 응용 분야 중의 하나이다. 가상현실을 의료 분야에 응용하는 연구는 학제간 연구의 대표적인 사례로 간주되며, 컴퓨터 과학자나 공학자, 내과 및 외과의사, 의학 교육자나 학생, 군사 의료 전문가들이나 의생명과학 전문가들이 참여하고 있다. 사용자들이 인지하는 물입감의 경험을 기준으로 하여 사람과 컴퓨터의 상호 작용(HCI, Human Computer Interaction)을 향상시키기 위해서는, 햅틱(Haptic), 음성, 냄새 등 비전통적 상호 작용 방법이 탐구되어야 한다. 특히, 햅틱 피드백은 전통적 상호작용 방식인 시각 정보와 서로 긴밀하게 관계가 맺어진다. 시각 정보와 햅틱 피드백을 결합하게 되면, 사용자들은 몰입감을 좀더 강하게 느끼게 된다. 전세계적으로 햅틱 피드백은 오랫동안 연구되어 왔고, 햅틱 기반의 시스템도 많이 개발이 되었다. 본 논문에서는 해틱 피드백이 의료 분야에 적용된 사례들에 집중하였다. 즉, 햅틱 피드백과 이들이 의료 분야에 응용된 사례들을 정리하여 발표하였다.

Itajahya rosea was found growing in association with Leucaena leucocephala plants at Savitribai Phule Pune University campus in India. The species identity was confirmed by phylogenetic analysis based on ITS and LSU regions of rDNA, wherein, our fugus was placed along with I. rosea in phylogenetic tree. It represents first record of I. rosea from India. Frequent visitation by Drosophila species on I. rosea fruiting body particularly on gleba was observed. The Drosophila got attracted to the detached gleba under the laboratory conditions and even sometimes, they prefer to sit over the gleba as compare to their food banana. It suggested that I. rosea gleba or pseudostipe produces some compounds for attraction and feeding behavior of Drosophila species. Therefore, we characterized the volatile attractants produced by gleba and pseudostipe of I. rosea by GC-MS analysis. Nineteen compounds were identified from gleba while nine compounds were recovered from the pseudostipe. Out of them, blends of three abundant odor producing volatile compounds were reported namely, Hexadecane, Pentadecane and Nonadecane, which are responsible for attraction of Drosophila toward the gleba. Three fatty acids namely 9,12-octadecadienoic acid (Z,Z), hexadecanoic acid and benzoic acid ethyl ester produced are served as an appetitive signal through olfactory response of Drosophila, so the flies were feed on the gleba. Two pheromones' compounds, heneicosane and (+)-(5S,9S)-5,9-dimethylpentadecane, were also reported in pseudostipe and gleba, respectively, which play a role in Drosophila for breeding. Our study highlights an intriguing chemical ecology of fungus-Drosophila interaction.

Background: Pollinators help plants to reproduce and support economically valuable food for humans and entire ecosystems. However, declines of pollinators along with population growth and increasing agricultural activities hamper this mutual interaction. Nectar and pollen are the major reward for pollinators and flower morphology and volatiles mediate the specialized plant-pollinator interactions. Limited information is available on the volatile profiles attractive to honey bees and bumblebees. In this study we analyzed the volatile organic compounds of the flowers of 9 different plant species that are predominantly visited by honey bees and bumblebees. The chemical compositions of the volatiles were determined using a head space gas chromatography-mass spectrometry (GC-MS) method, designed to understand the plant-pollinator chemical interaction. Results: Results showed the monoterpene 1,3,6-octatriene, 3,7-dimethyl-, (E) (E-𝞫-ocimene) was the dominating compound in most flowers analyzed, e.g., in proportion of 60.3% in Lonicera japonica, 48.8% in Diospyros lotus, 38.4% Amorpha fruticosa and 23.7% in Robinia pseudoacacia. Ailanthus altissima exhibited other monoterpenes such as 3,7-dimethyl-1,6-octadien-3-ol (𝞫-linalool) (39.1%) and (5E)-3,5-dimethylocta-1,5,7-trien-3-ol (hotrienol) (32.1%) as predominant compounds. Nitrogen containing volatile organic compounds (VOCs) were occurring principally in Corydalis speciosa; 1H-pyrrole, 2,3-dimethyl- (50.0%) and pyrimidine, 2-methyl- (40.2%), and in Diospyros kaki; 1-triazene, 3,3-dimethyl-1-phenyl (40.5%). Ligustrum obtusifolium flower scent contains isopropoxycarbamic acid, ethyl ester (21.1%) and n-octane (13.4%) as major compounds. In Castanea crenata the preeminent compound is 1-phenylethanone (acetophenone) (46.7%). Conclusions: Olfactory cues are important for pollinators to locate their floral resources. Based on our results we conclude monoterpenes might be used as major chemical mediators attractive to both honey bees and bumblebees to their host flowers. However, the mode of action of these chemicals and possible synergistic effects for olfaction need further investigation.

The enhancement of inquiry skills has been emphasized as a important objective of science education for a long time. Of these, the observation is not only a simple and basic skill, but also a very important skill, in aspect of gathering informations about the nature of all things around us, through interaction between the sense organs of body and objectives. The purpose of this study is to investigate the results of observations about the grasshopper(Oxya chinesis), made by the elementary student from the 3rd to the 6th grade, and to make use of them as the basic materials for the observative teaming and the evaluation of the observation ability. Through this study, the collected items of observation are as follows For grasshopper, a total of observation items is 95, 70 using the sight sense, 13 using the tactile sense,7 using the olfactory sense. 3 using the palate sense and 2 using the auditory sense. In this study, the findings of elementary student's observation are as follows. 1. On the whole, most of students have observed mainly by the sight and the tactile sense, when observing the grasshopper. 2. It is showed a tendency that the observation ability of student is increased with the higher grade in elementary school. 3. As the grade ascends. the observations with operating are increased, also the quantitative expression and interpretation about them are increased. 4. In the case of same grade, there is no significant difference between students' gender, though girls' ability of the observation showed somewhat higher than boys' 5. Occasionally, the interpretations on the observative facts made by student, are inaccurate. Basis on the above results, we suggested some directions for the improvement of the observative learning program in science classroom of elementary school. First, the teacher have to serve as a guide and encouragement in the observative learning class, to be accomplished the various observation, which all the sensory organ can be used by student than the sight sense. Second, to get elevated the ability of observation, it is necessary that some experimental tools(magnifying lens, stereoscope, auxiliary implements etc.) are utilized. Third, the teacher have to make often endeavors showing an example of operation, to be activated the atmosphere of operative observation.

자율주행 기술의 발달로 자율주행형 공유 차량에 대한 기대감이 확산하고 있지만, 공유 차량에서 '소유 만족감'을 느끼기 힘든 것이 사실이다. 본 논문에서는 자율주행형 공유 차량 탑승 단계에서의 커스터마이징을 통해 이러한 소유 만족감이 충족될 수 있는지에 대해 연구하였다. 이를 위해 선행연구 조사와 현재 공유 차량 이용상에서 만족/불편 요소에 사전조사를 진행했다. 이후, 커스터마이징 요소에 대한 선호도와 각 요소가 소유 만족도에 미치는 영향을 CVT를 통해 검증하였다. 사전조사 결과 후각적 요소와 인터랙션 요소가 소유 만족도에 더 큰 만족도를 주며, CVT 결과 탑승 요소의 커스터마이징을 통해 소유 만족도 충족이 가능할 것으로 나타났다. 본 연구를 향후 자율주행 차량의 인터랙션 디자인과 공유 차량의 서비스 디자인 연구를 위한 기초 자료로서 제시하였다.
