  • Sensory and consumer science is one of the four core sciences in food science training. In early years, this field of studies are focused on providing food technologists information of sensory attributes of food for quality control and product optimization, and referred as sensory evaluation or sensory science interchangeably. Yet, during the last decades, its scope has been much broadened looking at sensory properties of food not just as product attributes but consumer-perceived properties, emphasizing human experience. Attentions are increased for sensory fundamentals(sensory psychology and physiology) and multidisciplinary integration of theories and measurement methods for improving satisfaction of consumers' sensory experience and promoting healthy eating and wellbeing. The Sensory Evaluation(SE) division of Korean Society of Food Science and Technology(KoSFoST) has recently changed its name to Sensory and Consumer Science(SCS) division in order to address such evolution of the field and sensory professional's role.

  • Purpose: Oral and facial sensation is affected by various factors, including trauma and disease. This study assessed the clinical profile of patients diagnosed with sensory dysfunction and investigated their sensory perception using simple qualitative sensory tests. Methods: Based on a retrospective review of the medical records, we analyzed a total of 68 trigeminal nerve branches associated with sensory dysfunction in 52 subjects. We analyzed the frequency and etiology of sensory dysfunction, and the frequency of different types of sensory perception in response to qualitative sensory testing using tactile and pin-prick stimuli. Results: The inferior alveolar nerve branch was the most frequently involved in sensory dysfunction (88.5%). Third molar extraction (36.5%) and implant surgery (36.5%) were the most frequent etiological factors associated with sensory dysfunction. Hypoesthesia was the most frequent sensory response to tactile stimuli (60.3%). Pin-prick stimuli elicited hyperalgesia, hypoalgesia, and analgesia in 32.4%, 27.9%, and 36.8%, respectively. A significant association was found between the two kinds of stimuli (p=0.260). Conclusions: Sensory dysfunction frequently occurs in the branches of the trigeminal nerve, including the inferior alveolar nerve, mainly due to trauma associated with dental treatment. Simple qualitative sensory testing can be conveniently used to screen sensory dysfunction in patients with altered sensation involving oral and facial regions.

  • This systematic review compared Korean and international researches on sensory integration therapy in patients with autism spectrum disorder (ASD). We targeted studies on sensory integration therapy for patients with ASD published from January 2000 through July 2016. Specifically, we analyzed the papers that used the phrase 'sensory integration, autism' as keywords. There were fewer Korean studies of sensory integration therapy, and the diversity of research topics were limited, focusing mainly on case studies. There was no difference between the internal/external validity of Korean and those of international studies targeting the clinical environment and patients. Further study of a variety of aspects of sensory integration therapy is needed to gain high internal/external validity.

  • The person's behaviors are interactive with sensory processing ability. So sensory processing ability is very important. Most of tools which evaluate sensory processing are developed for the child. But sensory integrated problems are not restricted to the child. It is possible for sensory integrative problems to happen independent of the intellectual level and the social stratum. And sensory integrative problems are distributed in all age. Adults who have a sensory defensiveness use various coping strategies. But it does not solve a basic sensory defensive problem. Previous studies reported the fact that the sensory integrative treatment has a high treatment effect in these people. In this paper, we present the necessity for adult's sensory processing evaluating tool. We introduces Adolescent/Adult Sensory profile to be translated into Korean. It will discriminate adults who have sensory defensiveness from adult. It will provide these people with the suitable help.

  • The present study was performed to assess peripheral neural involvement by exposure to hand-arm vibration. Segmental sensory nerve conduction in the median and ulnar nerves were measured in shipyard workers exposed to vibration. The subjects were 47 male adults exposed to hand-arm vibration and 7 healthy male controls. The subjects underwent an extensive bilateral neurophysiological examination. Sensory compound nerve action potential (SNAP) of the median and ulnar nerves in palm-finger and wrist-palm segments were measured by antidromic method. And SNAP of the median and ulnar nerves in wrist-proximal finger and wrist-distal finger segments were measured by orthodromic method. Result of sensory nerve conduction study was abnormal in 31 patients $(66\%)$ and normal in 16 patients $(34\%)$ of subjects. The pathological pattern in the hand-arm vibration exposed group was 13 patients $(28\%)$ of carpal tunnel syndrome, 18 patients $(38\%)$ of distal sensory neuropathy, 7 patients $(15\%)$ of multifocal and 1 patient $(2\%)$ of Guyon syndrome. The present study indicates that vibration-induced nerve impairments exist both in the finger-palm and palm-wrist segment of median and ulnar sensory nerves. The results suggest that segmental sensory nerve conduction study would be useful as objective indication of peripheral nerve impairment induced by the hand-arm vibration.

  • Sensory quality variations of jajang sauce were monitored by the $\bar{X}-chart$ and capability analysis based on specifications of each sensory attributes. For sensory quality control (QC) of the sauce which has a strong sweetness and sourness, the ratio of sourness/sweetness was examined as a necessary QC factor to maintain the balance of sweetness and sourness. For the sensory QC factors, all the sensory data were divided into individual sensory score of reference which was a pack of sauce manufactured a week ago. The ratio form of sensory data was useful for decreasing individual variations and for increasing normality of data measured by category scale. The overall proportion of out-spec products under normal manufacturing conditions was obtained by capability analysis of sensory data with normal distribution. Out-spec samples were monitored by the $\bar{X}-chart$ of each sensory attributes.

  • Various sensory technologies have been used at different stages of product development. In this paper, the examples of sensory studies in teas and cosmetics were shown, and these could help to increase the contribution of sensory sciences to the development of products in the industry. In classical approach, descriptive analysis with trained panel and consumer acceptability test are very important to identify the sensorycharacteristicsthatdriveconsumeracceptability of products. Recently, some quick and easy sensory evaluation methods were introduced such as CATA (check-all-that-apply), sorting, and $Napping^{(R)}$, etc. to gather information about consumers' perception of the sensory characteristics of products. Although there are many sensory methodologies available in the product development phase, the most important thing is that these have to be correctly selected and designed for target consumers, products, and research purposes in order to develop a successful product.

  • Objective: This study was to provide a standard for the evaluation of The Korean version of Adolescent/Adult Sensory Profile(K-ASP) for University students and to investigate the difference of the subjective sense recognition regarding the characteristics of sensory processing. Method: The subjects consisted of 84 University students. A researcher examined subjective sense recognition and K-ASP for subjects. Visual Analog Scale used to evaluate subjective sense recognition and K-ASP was utilized to evaluate the characteristics of sensory processing. Results: 1. The average scores and standard deviation of K-ASP were $32.93{\pm}7.88$ for low registration group, $39.39{\pm}6.55$ for sensory seeking group, $38.94{\pm}9.13$ for sensory sensitivity group, and $34.24{\pm}7.85$ for sensory avoiding group. 2. The correlation between the total score on an each quadrant and the subjective sense recognition are -.27 for low registration group, .11 for sensory seeking group, .09 for sensory sensitivity group and .12 for sensory avoiding group. It showed the statistically significant correlation between the total score of low registration and the subjective sense recognition group(p<.05). 3. The average scores and standard deviation of the subjective sense recognition were $5.22{\pm}1.56$ for high threshold and $7.28{\pm}1.70$ for low threshold. The subjective sense recognition according to the characteristics of sensory processing showed the statistically significant difference. Conclusions: This study supports the theory that there is the difference of sensory recognition according to each individual and we found that people with difficulties of sensory processing acknowledge their characteristics of sensory processing well. Evaluation of sensory processing ability through interview or questionnaire supports the fact which it is reliable.

  • To confirm the influence of modified starch on frozen storage stability, the microstructure and sensory characteristics of fish cakes, called Eomuk in Korea, by using seven varieties of starch, including native starch (NS), physically treated corn starch (MS) and modified starch [treatment with acetate (SA-1, SA-2 and SA-3), hydroxypropyl (HS), and acetylated distarch adipate (ADA)] were evaluated. Scanning electron microscopy (SEM) photographs showed fish cakes with NS had a finer and denser network structure than those made with modified starches. During frozen storage, fish cakes with HS and ADA exhibited a stable structure, as evaluated by porosity and rough surface. The results of the sensory evaluation showed that modified starch, including HS, SA-2 and ADA, increased the taste and firmness of the fish cakes, while NS, MS and the modified starch SA-3 resulted a decrease in the sensory properties during storage. Therefore, HS, SA-2 and ADA are suitable additives to improve the sensory quality of frozen fish cakes.
