Based on the Minimalist Program (Chomsky, 1995) as a method for mental wellness, this study integrates aroma, flavor, and sound into <iColour(internalized colour)>, which develops from the human cognitive system. This study further systematizes aroma, flavor, and sound language to create <iColour Sensory Lexicon>. Visual images are connected with shapes, sounds, touches, and flavors, enabling high-level interactions in human cognitive processes (Kim, 2020; Olivetti Belardinelli et al. , 2004). <iColour Sensory Lexicon> approaches the sensory characteristics of aroma, flavor, and sound using universal language of internalized colour, and presents a new standard for visual sensory lexicon. The language of aroma, flavor, and sound can be expressed in the language of thought presented in <iColour Sensory Lexicon>, and their properties and essences can be easily understood through clarified language. 본 연구는 정신적 웰니스(mental wellness)를 위한 방안으로 촘스키 최소주의(The Minimalist Program(Chomsky, 1995)) 접근법에 근거하여, 인간의 인지체계(cognitive system)에서 발생하는 내면화된 색상(internalized colour)으로, 아로마・향미・소리를 ‘iColour(internalized colour)’로 통합하였으며, 아로마・향미 언어와 소리 언어를 체계화하여 <iColour(internalized colour) 센서리 렉시콘>을 제작하였다. 시각적 이미지는 형태(shapes), 소리(sounds), 촉각(touches), 향미(flavors) 등과 연결되어, 인간의 인지 과정에서 높은 수준의 상호 작용을 가능하게 한다(김성헌, 2020; Olivetti Belardinelli et al., 2004). <iColour 센서리 렉시콘>은 아로마・향미・소리의 감각적 특성을 보편적 언어인 내면화된 색상(internalized colour)을 활용하여 시각적으로 접근하였으며, 새로운 시각적 감각 어휘의 기준을 제시한다. 또한 아로마・향미 언어와 소리 언어를 표현(description)함에 있어 <iColour 센서리 렉시콘>에서 제시하고 있는 사유의 언어로 표현할 수 있으며, 명료화된 <iColour 센서리 렉시콘> 언어를 통해 향미와 소리의 속성과 본질을 쉽게 이해할 수 있다.

Objective: To compare the detection performance of the automated whole breast ultrasound (AWUS) with that of the handheld breast ultrasound (HHUS) and to evaluate the interobserver variability in the interpretation of the AWUS. Materials and Methods: AWUS was performed in 38 breast cancer patients. A total of 66 lesions were included: 38 breast cancers, 12 additional malignancies and 16 benign lesions. Three breast radiologists independently reviewed the AWUS data and analyzed the breast lesions according to the BI-RADS classification. Results: The detection rate of malignancies was 98.0% for HHUS and 90.0%, 88.0% and 96.0% for the three readers of the AWUS. The sensitivity and the specificity were 98.0% and 62.5% in HHUS, 90.0% and 87.5% for reader 1, 88.0% and 81.3% for reader 2, and 96.0% and 93.8% for reader 3, in AWUS. There was no significant difference in the radiologists’ detection performance, sensitivity and specificity (p > 0.05) between the two modalities. The interobserver agreement was fair to good for the ultrasonographic features, categorization, size, and the location of breast masses. Conclusion: AWUS is thought to be useful for detecting breast lesions. In comparison with HHUS, AWUS shows no significant difference in the detection rate, sensitivity and the specificity, with high degrees of interobserver agreement.

Benign paroxysmal positional vertigo (BPPV) is a most common cause of vertigo. Although endolymphatic flow which is caused by movement of detached-otoconia from otolithic organs has been suggested as a cause of positional vertigo, none has proved it in the human inner ear. Therefore, there were many trials to explain the anatomical characteristics of cupula, physiology of cupula deviation, pathologic mechanisms of BPPV, and clinical characteristics of BPPV using animal membranous labyrinth. In this review, results of basic animal experimental studies to understand anatomical structures and pathological mechanisms related to BPPV are introduced. In addition, future directions for experimental studies to elucidate the mechanism of BPPV will be suggested.

Na+ homeostasis in the inner ear is important to maintain normal hearing and balance. Na+transport in the inner ear is reported to be occurred in non-sensory epithelium of inner ear which forms a barrier between endolymphatic space and perilymphatic space. Functionally identified and constitutively active Na+ absorption sites in the inner ear are Reissner’s membrane, outer sulcus cells, vestibular transitional cells, saccular nonsensory epithelial cells, and endolymphatic sac epithelial cells. Na+ transport in these epithelial cells is mediated by apically located epithelial Na+ channels (ENaC), nonselective cation channels and basolaterally located Na+, K+-ATPase. Na+ absorption is increased by glucocorticoid through glucocorticoid receptor or ATP through purinergic receptors depending on cell types. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:399-407
