The eyes are the first sensory organs to perceive the environment. We become accustomed to the environment with our eyes. When we contact the environment, we perceive the appearance of an object with our eyes. Then we recognize our position, and perceive the shape surrounding the object interacting with space. The perception of seeing constructs experiences which control most of our recognition, and the experiences are images of the environment surrounding it. So they are significantly expressed into sensitive and mental elements of material and non-material world. Gibson's ecological perception theory analyzes and information system, which helps man to move effectively, and its component stimulus'. The important thing is that we should understand the combination of systems gathering stimulus not as an individual system but as one whole system.

One of the problems we frequently face during the ROK and US Combined operations is the English Military abbreviations because they often causes a lot of confusion. Many military abbreviations we generated, changed, and disappeared, so it is very hard to figure out their meaning sometimes. This system is designed to make it easier to register, alter, and find out English abbreviations through hypermedia techniques, which is utilizing nonsequential and direct search system similar to human sensory organs. So this enables us to keep up with the latest abbreviations. It is also designed to overcome mutual communications barriers by audio-visual aids through the graphic and phonetic functions of the program, and to test users via a random selection of questions.

Maintaining internal homeostasis and regulating innate behaviors are essential for animal survival. In various animal species, a highly conserved neuroendocrine system integrates sensory inputs and regulates physiological responses to environmental and internal changes. Diuretic hormones 44 and 31, which are homologs of mammalian corticotropin-releasing factor (CRF) and calcitonin gene-related peptide (CGRP), respectively, control body fluid secretion in Drosophila. These neuropeptides and their receptors have multiple physiological roles, including the regulation of body-fluid secretion, sleep:wake cycle, internal nutrient-sensing, and CO₂-dependent response. This review discusses the physiological and behavioral roles of DH44 and DH31 signaling pathways, consisting of neuroendocrine cells that secrete DH44 or DH31 peptides and their receptor-expressing organs. Further research is needed to understand the regulatory mechanisms of the behavioral processes mediated by these neuroendocrine systems.

This study developed a method to minimize rice damages and enhance timely control by accurately classifying Whitebacked Planthopper (WBPH). The body size of the 1st-3rd instar was 1.5-2 mm, and the body size of the 4-5 instar was 2.5-3.5 mm. In the third instar, the ratio of the front wing bud and the back wing-bud was 1:1. The fourth instar occupied 3/4 of the front wing-bud, and the 5th instar showed that the front wing-bud covers the back wing-bud. It was confirmed that the 1st instar does not have a sensory plate, the 2nd instar has 2-3, the 3rd instar has 4-5, the 4th instar has 6-9, the 5th instar has 10-15, and the adult instar has 15-20 sensory plates. The female spawning organs were reddish when the spawning horn was inserted. WBPH showed that the larvae of 2-3 larvae most actively feed on rice, and the damaged area was the stem of rice near the ground. In addition, a partial black wound was observed after the feeding. WBPH-susceptible 'Chucheong' was yellowish, and early growth was slower than that of 'Cheongcheong', which was resistant; moreover, a difference between susceptibility and resistance was observed. The identification of the number of such wounds in the bioassay will be a better basis for understanding the difference in susceptibility between WBPH strains and cultivars. These results will be used as basic data for cultivating the WBPH-resistant varieties of rice.

Objectives : Acupuncture is expected to have somewhat like the efficacy parallel increasing activity of immune system in Western modem medicine. There, already, are many animal researches on activating effect of acupuncture for the immune system in peripheral organs. So, we carried out this experiment to see whether acupuncture has controlling effect on interleukin-6(IL-6) activity in rat's brain. Methods and Results : We had topical application of IL-6(1U=lpg, $10{\mu}l$) on brain of rat. It reduced afferent sensory transmission to the primary somatosensory(SI) cortex from periphery. Whereas, electrical stimulation(ES, 2Hz, 1.5V, 15min) of ST36(足三里) with application of IL-6 prominently activated afferent sensory transmission. ES of non-acupoint(proximal tail) with IL-6 showed suppression of afferent transmission. ES of ST36 without IL-6 application also exerted facilitation of afferent transmission to the SI cortex. Conclusions : Electoacupuncture(EA) on ST36 has noticeable influences on modulating activation of IL-6 in central nervous system, which do major role in immune system.

This experiment was planned to develop a functional supplements by food resources to prevent and lessen the bad effects caused by the environmental pollution such as bad food, air, water and heavy metals exposed to people these days. As for Its primary stage, the nutrient profile and sensory characteristics of the duck-extract were evaluated in this study. The duck-extract was formulated by the mixture of bone and internal organs of ducks and 6 medicinal herbs which were able to be used as foods and known to help the excretion and the repression of the poison inside the body for a long time. As we compared the six medicinal herbs mentioned above to the vegetable herbs, the nutrient profile of the medicinal herbs were superior to the vegetable herbs. The duck-extract was composed of protein 49.92%, carbohydrate 37.02%, dietary fiber 20.99%, lipid 7.60% and ash 5.46%. The ratio of Ca to P was 1 : 1.4, which was a suitable ratio for absorption, the contents of Na and K were low and those of micro-elements such as Fe, Mn, Zn and Cu high compared to other meat extracts. The essential amino acids accounted for 30.91% of total amino acids. The result of sensory evaluation was better in overall preferences than the ones which are already in the market. From these results, the nutrient profile of the duck-extract was estimated to be able to supply enough nutrients to the people whose nutritional balance was destroyed these days. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

The purpose of this study was to analyze the understanding of the sighting and hearing elementary school students have through drawing. For this purpose, we conducted a questionnaire survey of 602 elementary school students. The questionnaire was composed with open-ended question developed by West et al.(2008). This questionnaire was presented only appearance of face. And let them express the sensory pathway by drawing and writing. The students' responses for questionnaire were classified by 5 levels. Inner-researcher consistency was 0.89, inter-researcher consistency was 0.83. The data analyzed were ${\chi}^2$ by using SPSS. The result of this study were as following: First, elementary school students have misconception of sighting and hearing. There were no difference among the grade. In spite of becoming upper grade, students have still misconception. Second, scientific concept that male students have were significantly more than female. Third, the concepts of the anatomically organs are more exposed in real-life situations, students known better. Within these results, it would be used for developing teaching-learning strategies which can use misconceptions students have.

Although past design developments that emphasized only the outer appearances of products were mostly concentrated on the areas of forms and colors in an attempt to satisfy humans' visual needs, it is expected that future designs to come will go in the direction to stimulate more diversified human senses. This means expansions to the five senses including the auditory sense, the sense of smell, the tactile sense and the taste and even to the area of synesthesia where two or more senses are stimulated or coexist. Although the dictionary definition of synesthesia is a concept of arousing another sense through a sense, studies of synesthesia in design go one step further from here to mean compound senses, that is, the synesthesia in an expanded meaning to feel an object (thing) through many sensory organs simultaneously. The synesthesia in the expanded meaning is applying multiple senses simultaneously in recognizing one thing to comprehensively judge and feel the thing. Recent design trends are going in a direction to basically satisfy humans' visual needs through controlled forms and colors while inducing another new feeling through expressions of diverse feels of materials within existing forms. In this change of the times, studies on furniture designs are conducted through factors of in synesthesia linked with other senses and have an important meaning that can enhance the value of designs.

This paper presents a capacity estimation of a storage system accumulating all data sensed during the lifetime of an individual human being. The calculation assumes modern data compression and data collection schemes based on wearable or implanted devices under ubiquitous environment. More than 76% of the storage area is found to be used for video data storage of common TV image quality. The remaining storage area is for data from other sensing organs including audio, taste, olfactory and tactual systems in addition to indexing information. Total storage area of around 600 tera bytes is needed to cover 100 years of human life including his fetal period.

The nation is turning into aging society, and safety accidents among elderly people are on the rise. When death roll caused by safety accidents was investigated, senior citizens who died from safety accidents outnumbered the other age groups who died for the same reason. The most common cause of death was traffic accidents, followed by suicide and a hurt from a fall, and Korea rated first among OECD member nations in death roll by traffic accidents. Aging brings a lot of physical changes to elderly people, and they are often likely to be involved in accidents such as a hurt from a fall due to degenerated sensory organs like hearing and eyesight and deteriorated motor skills. Unsafe social facilities also have them face a lot of accidents, including fracture and death, and such accidents take place even at home that is usually considered safe, or are triggered by things of daily use. As a result of comparing every age group's death roll by safety accidents, the number of senior citizens who died from safety accidents was far higher than that of the other age groups who died for the same reason in every accident field. In aging society, a sharp increase in the elderly population and ensuing safety accidents are expected to pose a serious threat to national economy, and diverse efforts should be put into tacking this problem. For instance, safety education should be provided to people in general including senior citizens on a regular basis, and more safety facilities should be prepared. Besides, safety equipment should be developed.
