In a sensory evaluation, the data obtained by a result of evaluation have a wide dispersion and fuzziness because human sense organ is used as a means of measuring sensation instead of measuring instruments. These dispersion and fuzziness are caused by all kinds of time error and have a great influence on a sensory evaluation, but most of previous papers don't deal with these time errors. In this study, a comparative judgement capacity of an evaluator is discriminated by means of the eigen-structure analysis on the premise that evaluation value of sensory evaluators obtained by a paired-comparison become different by the order of sample presentation

한국 고유종 돌마자 Microphysogobio yaluensis의 후각기관과 서식처 및 생태와의 연관성을 알아보기 위해 실체 현미경과 광학현미경을 이용하여 구조 및 조직학적 특징을 조사하였다. 후각기관은 외부적으로 전비공, 후비공 그리고 비경계판으로 구성되어 있으며, 내부는 22~24개의 후판들과 비선으로 구성되었다. 후판은 감각상피와 비감각상피로 이루어져 있는데, 감각상피는 후감각신경, 지지세포, 기저세포들로 구성되었으며, 비감각상피는 층상상피세포, 비감각섬모세포, 산성과 중성을 갖는 황점액소의 점액세포들로 구성되어 있다. 이러한 후각기관들의 특징들은 돌마자의 높은 후각능력과 의존성 그리고 서식처 환경에 밀접한 관계가 있을 것으로 생각되며 분류학적 연구에도 활용될 수 있을 것으로 생각된다.

The histology and anatomy of the olfactory organ in Luciogobius guttatus was investigated using a light microscopy and scanning electron microscopy. The paired olfactory organs in the dorsal part of the snout are situated in between the upper lip and the eyes. They consist of two nostrils, one anterior and the other posterior openings, and a single olfactory cavity. The anterior nostril, an incurrent opening, forms a short tubular structure from the skin. The posterior nostril, an excurrent opening, forms a circular structure opened to the exterior. The distributional pattern of the sensory epithelium is a continuous type. The sensory epithelium with numerous-motile cilia is made up of receptor cells, supporting cells, basal cells, and mucous cells. In contrast, the non-sensory epithelium is comprised of stratified epithelial cells and two types of mucous cells, acidic and neutral cells. The cilia number of the receptor cell is in range of 3 to 4 units. Such results in L. guttatus may reflect its ecological habit and microhabitat in the tidal zone with a periodic tide.

The vomeronasal organ (VNO) is a sensory organ that influences social and/or reproductive behavior and, in many cases, the survival of an organism. The VNO is believed to mediate responses to pheromones; however, many mechanisms of signal transduction in the VNO remain elusive. Here, we examined the expression of proteins involved in signal transduction that are found in the main olfactory system in the VNO. The localization of many signaling molecules in the VNO is quite different from those in the main olfactory system, suggesting differences in signal transduction mechanisms between these two chemosensory organs. Various signaling molecules are expressed in distinct areas of VNO sensory epithelium. Interestingly, we found the expressions of groups of these signaling molecules in glandular tissues adjacent to VNO, supporting the physiological significance of these glandular tissues. Our finding of high expression of signaling proteins in glandular tissues suggests that neurohumoral factors influence glandular tissues to modulate signaling cascades that in turn alter the responses of the VNO to hormonal status.

The present condition of study on the wave-resonance for the bio-KI is observed. And the probroms of reception attendent on the stimulation of wave is observed centering around the sensory organ. The results is as follows: In the wave-resonant stand point, the tendency of studying on KI is showed in the several field all over the world. Because it is originated radionics, the wave-resonant tools of MRA insistenting minute-magnetism-resonance-apparatus need the more severe data in the side of electric circuit. The wave resonance apparatus according to the frequency occurance transmits low-frequency's vibration ratio to the electric stimulating aspect. The wave-water is considered on the application of wave-resonance transcription on the water, and needs the comprehension of torsion-field level. The wave-stimulation of the bio-KI and the reception of the sensory-organ is observed the connection of the sensory-organ and it's corresponding wave. The informations recorded in the wave are distinguished patternly. And the several shaping waves transmit the informations each other through the resonnance. The wave theory is explained the LEE(理) as the wave-pattern and the KI(氣) as the revelation of the patterned-wave in the LEE-KI theory(理氣論), moreover the SHIN(神) as the information of the wave-pattern and the KI as the energy of the wave and the JEUNG(精) as the material of the wave in the JEUNG-KI-SHIN theory(精氣神論). In this point, the study on the wave-resonance of bio-KI is thought that it is significantly in the study method for oriental medicine. The sum of the wave makes the moving body and forms the universe. It means that the several wave patterns gather and form new field. The pattern is a kind of the information and the information is not materially. The information of wave-pattern is the arrangement and the combination of the material source.

한국 고유종 각시붕어 Rhodeus uyekii의 후각기관과 서식처의 물리 및 화학적 특성 그리고 생태적 습성과의 연관성을 알아보기 위해 실체현미경, 광학현미경, 주사전자현미경을 이용하여 해부 및 조직, 세포화학적 특성을 조사하였다. 후각기관의 외부형태는 반원의 전비공과 후비공, 비경계판으로 구성되는데, 특히 전비공의 앞쪽에는 아치형의 조직이 돌출되어 있다. 비강 내에는 14~15개의 후판으로 구성되는 로제트 구조를 보유하며 후판은 감각상피와 비감각상피로 구분된다. 감각상피는 후감각뉴런, 지지세포, 기저세포, 림프구, 형질세포로 구성되는 반면에 비감각세포는 층상상피세포, 점액세포, 비감각섬모세포, 미확인세포가 1종류 확인된다. 점액세포의 세포화학적 특성은 산성 및 중성의 황점액소(sulfomucine)로 나타났다.

The olfactory anatomy and histology of Lethenteron reissneri were researched using a stereo microscope, a light microscope, and a scanning electron microscope. As in other lampreys, it shows same characters as follows: i) a single olfactory organ, ii) a single tubular nostril, iii) a single olfactory chamber with gourd-like form, iv) a nasal valve, v) a nasopharyngeal pouch, vi) a sensory epithelium (SE) of continuous distribution, vii) a supporting cells with numerous long cilia, viii) an accessory olfactory organ. However, the description of a pseudostratified columnar layer in the SE and Non SE is a first record, not reported in sea lamprey Petromyzon marinus. In particular, both 19 to 20 lamellae in number and olfactory receptor neuron's quarter ciliary length of the knob diameter differ from those of P. marinus. From these results, it might be considered that the olfactory organ of L. reissneri shows well adaptive structure of a primitive fish to slow flowing water with gravel, pebbles, and sand and a hiding habit into sand bottom at daytime. The lamellar number and neuron's ciliary length may be a meaningful taxonomic character for the class Petromyzonida.

Optimum preparation conditions for chicken head soup base were determined in terms of the effects of amount of chicken head and cooking time using response surface methodology based on sensory properties. Sensory properties that were evaluated were yellowness, turbidity, bloody, chicken-brothy, organ meat-like, and fat-like flavor. All values of sensory characteristics increased remarkably with an increase in the amount of chicken head and cooking time. The optimum amount of chicken head and cooking time were determined to be 1800 g and 150 minutes, respectively. Chicken head soup base had less fat, free amino acids, nucleotides, and its derivatives, but had significantly more cholesterol, sodium, and iron than whole chicken soup base. In flavor compound analysis, the amount of hexanal of the chicken head soup base, which is related to fat rancidity flavor, was 11-fold higher than that of the whole chicken soup base.

Gulgastrura reticulosa, first described by Yosii (1966) as a monotypic new genus from a Korean limestone cave, was reviewed for its systematic position by c1adistic analysis of morphological characteristics, investigation of its intermaulting period and reproductive cycle as well as allozyme and 18S rDNA analysis. The great extent of divergence was strongly suggested by its combined lack of sensory organs (third antennal organ, postantennal organ, eyes, pseudocelli) with simultaneous development of an 'apical organ'at the tip of the antennae. The obvious divergence from any existing Collembola families was additionally supported by the extremely prolonged intermoulting period as well as by the low strap value it showed with Onychiuridae as obtained by 18S DNA sequence analysis. All these were considered Justifying the creation of a new family, Gulgastruridae, but still revealing more allied to Onychiuvidae rather than to Hypogastruridae.
