  • 시청각정보를 통한 영상미디어의 실감향상에 대해서는 많은 진보가 이루어져 왔다. 반면 영상실감을 위한 후각정보의 제시는 기술적 구현과 통제가 어려워 관련연구를 찾아보기 힘들다. 본 연구는 영상실감을 위해 후각정보를 제시하고자 할 때 필요한 기초자료를 획득하기 위해, 영상에 존재하는 후각정보에 대한 사용자 지각을 조사한 후 이에 근거하여 다양한 영상을 분류한 것이다. 이를 위해 먼저 영상에 냄새가 존재하는지 (냄새존재여부), 영상과 함께 해당 냄새를 경험하고 싶은지 (냄새제시선호), 해당 냄새가 내가 좋아하는 냄새인지 (냄새자체선호), 해당 냄새가 제시된다면 강도는 어느 정도면 좋을지 (냄새제시강도), 그리고 영상 속의 냄새가 얼마나 구체적인지 (냄새의 구체성)라는 다섯 가지 질문을 선정하였다. 이 질문들에 대해 높은 혹은 낮은 평정을 받을 만한 다양한 장르의 영상을 수집한 다음, 참가자들에게 하나씩 시청하게 한 후 위의 다섯 가지 질문에 대해 7점 척도로 평정하게 하였다. 영상분류를 위해 위 다섯 가지 질문을 2개씩 쌍으로 묶은 후, 각 질문에 대한 평정값을 2차원 평면의 X-Y축으로 설정하여 영상산포도를 구성하였다. 산포도를 통해 드러난 영상군집과 그 형태는 해당 영상군집이 가진 특성에 대한 통찰을 제공함과 동시에 영상실감을 위한 후각정보 제시에 중요한 시사점을 줄 것으로 기대한다.

  • Purpose: This study aims to study the perception of merchants and customers about the odor problem of traditional markets in Wonju, Gangwon-do. Research design, data and methodology: A survey was conducted to investigate the perception. The survey consisted of 11 questions for merchants and 12 questions for customers. Results: In a survey of merchants - The question 'What kind of smell did you smell at the traditional market?' was investigated with multiple responses. Regarding the odor experience, unclean odor was the highest with 105 votes (36%), followed by rotting odor with 82 votes (28.1%) and other odors with 44 votes (15.1%). In a survey of customers - The question 'What kind of smell did you smell at the traditional market?' was investigated with multiple responses. As a result of the survey, filthy smell was the highest with 98 votes (43.2%). Next, rotten smell was found with 60 votes (26.4%) and others with 31 votes (13.7%). Conclusions: If the odor problem in the traditional market is solved, the economic and health damage to the merchants will be reduced. Further, it will help to revitalize traditional markets by increasing customer visits. As a solution, it is judged that it is good to study the direction of the establishment of a real-time monitoring system and the preparation and application of odor removal measures.

  • 후각은 가장 민감한 감각 기관으로 다른 감각에 비해 아직 많은 연구가 이루어져 있지 않다. 후각의 이론적 접근은 100년도 안되는 역사를 가지고 있고, 후각세포에서 일어나는 전기적 신호를 측정한 것은 50년 전의 일이었다. 최근들어 후각의 산업적 응용에 대한 관심으로 인해 많은 연구가 진행중이다. 본 고에서는 후각의 신호 전달 과정을 이해하기 위해 포유 동물과 곤충의 후각 기관의 구조를 비교하고 각각의 인지 과정을 분자 수준에서 살펴보았다. 또한 후각 기관의 냄새 인지 과정을 이해하여 후각 센서로의 이용 가능성에 대해 검토하고, 현재 후각 센서의 개발 현황을 알아보았다. 후각에 대한 연구는 앞으로 센서산업에 많은 기여를 할 것으로 기대된다.

  • This study analyzed the Food Neophobia Scale (FNS) and Korean food perception status of Southeast Asian workers living in South Korea in order to build up basic data to develop a desirable diet program. From our study, we found that FNS was higher in the order of Cambodian, Myanmar, Vietnamese, and Thai workers. Influential demographic factors for FNS were cooking possibility and place of residence. The mean scores of Cambodian workers ($3.46{\pm}0.63$) regarding "positive perception of cooking method, taste & color" about Korean food were the highest among the four countries, followed by Vietnam ($3.38{\pm}0.68$), Myanmar ($3.26{\pm}0.50$), Thailand ($3.09{\pm}0.64$)workers(p<0.01). The mean scores of Myanmar workers regarding perception of "difference in cooking method, smell & texture" and "difference in taste" were the highest among the four countries. FNS had a negative correlation with the factor "positive perception of cooking method, taste & color" regarding Korean food and a positive correlation with the factors "difference in cooking method, smell & texture".

  • To develop customized food products for gastric cancer patients, it is crucial to understand their dietary characteristics and changes in their perception of smell and taste due to their condition. This study conducted in-depth interviews and administered olfactory and gustatory tests on 20 patients with gastric cancer. A control group of 20 healthy, gender and age matched individuals, was included for comparison. Patients reported difficulties in sustaining their appetite, particularly during chemotherapy. This could be attributed to gastrointestinal discomfort and an altered perception of smell and taste. The olfactory test revealed that cancer patients were significantly less sensitive than the control group. Also, a smaller number of participants in the cancer group were reported to have a normal taste function, which enabled them to perceive umami, one of the five basic taste compared to those in the control group. These findings demonstrated that gastric cancer patients experience post-surgical digestive issues, chemotherapy-induced changes in smell and taste, and appetite loss. To improve the quality of life of these patients and the efficacy of the treatment, it is necessary to consider not only their nutritional requirements but also other factors such as appetite loss and discomfort when developing meals specifically for them.

  • We present a case report of a 52-year-old male patient who suffered head trauma in a car accident and subsequently experienced taste and smell disorders. Following the accident, the patient reported difficulty detecting salty and sour tastes and diminished olfactory perception. Neurosurgical evaluation revealed subarachnoid and subdural hemorrhages, while otolaryngology investigations revealed hyposmia-a decreased sense of smell. Upon referral to the Department of Oral Medicine, a comprehensive assessment revealed a general bilateral reduction in taste sensation, particularly ageusia for salty taste. Electric taste-detection thresholds significantly exceeded the normal ranges. Integrating our findings from neurosurgery, otolaryngology, and oral medicine resulted in a diagnosis of mixed chemosensory disorder attributed to head trauma. This case highlights the intricate interplay of alterations in taste and smell following head injury, emphasizing the significance of multidisciplinary evaluations in diagnosing mixed chemosensory disorders resulting from traumatic brain injury.

  • This study examined consumer perceptions and consumer responses of Halal cosmetics and compared them with vegan cosmetics, which is a term similarly used. Twitter API of Python 3.7 was used to collect the keywords '#halalcosmetics' and '#vegancosmetics'. First, the main perception of consumers on Halal cosmetics focused on the original concept, image, expected efficacy, and factors to consider before purchase, religious keywords, labels and packaging for Halal cosmetics. Second, the main consumer perception of vegan cosmetics was the product concept, expected efficacy, factors to consider before purchase, related vegan industry, image, and vegan cosmetic components. Third, the consumer perceptions of Halal cosmetics and vegan cosmetics were similar in multiple ways, and both concepts included the Cruelty-free concept. Fourth, consumer satisfaction factors included cosmetics color, brand's consumer service, efficacy, smell, packaging design, reasonable price, effects, and formulation of cosmetics as well as satisfaction with Halal certification, and satisfaction of Vegan consumers. Consumer dissatisfaction factors included smell, flavor, delay in shipping, dissatisfaction with formulation, discrepancy between actual color and computer screen, concern and distrust about the use of prohibited ingredients for Halal products. This study examined consumer perceptions and reactions to Halal and vegan cosmetics to create basic knowledge for niche markets that are emerging as an ethical beauty consumption trend.

  • In response to diverse external stimuli, sensory receptors generate spiking nerve signals. These generated signals are transmitted to the brain along the neural pathway to advance to the stage of recognition or perception, and then they reach the area of discrimination or judgment for remembering, assessing, and processing incoming information. We review research trends in neuromorphic sensory perception technology inspired by biological sensory perception functions. Among the various senses, we consider sensory nerve decoding technology based on sensory nerve pathways focusing on touch and smell, neuromorphic synapse elements that mimic biological neurons and synapses, and neuromorphic processors. Neuromorphic sensory devices, neuromorphic synapses, and artificial sensory memory devices that integrate storage components are being actively studied. However, various problems remain to be solved, such as learning methods to implement cognitive functions beyond simple detection. Considering applications such as virtual reality, medical welfare, neuroscience, and cranial nerve interfaces, neuromorphic sensory recognition technology is expected to be actively developed based on new technologies, including combinatorial neurocognitive cell technology.
