The aim of this study was to measure effects of the following items to pain and pain behavior reaction in patients with chronic orofacial pain. Items that contribute to the first factor(Environmental Influences) measure environmental sources of information that may affect illness behavior; Second factro(Loss of Control) measure appraisals and attributions perceived to influence personal views aobut pain; Third factor(Health Care Avoidance) measures a variety of avoidant behaviors; Fouth factor(Past and Current Experiences) measures experiences with treatment); Fifth factor(Physiological Responsivity) measures physiological parameters that are experienced in association with pain; Sixth factor(Thoughts of Disease Progression) measures thoughts regarding the etiology and progression of disease in relation to pain. 150 patients that were consist of 40 male and 110 female were participated in this study. The obtained results of this study were as follows : 1. Environmental influences and loss of control scales were recorded high score in patients with chronic orofacial pain 2. "Physician's descriptions of what your pain will be like" and "Physician's facial expression when they ask about your pain" items from the environmental influences were recorded high score. These results indicated that responsibility of doctro is very important to the pain reaction behavior of patients. Also, items from thoughts regarding the etiology and progression of disease in relation to pain influenced to the pain reaction. 3. There were significant defferences on the "nurses' descriptions of what you pain will be like", "physician's and nurses' facial expression when they ask about your pain", "TV and radio", and "Literature" items from the environmental influences between male and female patients. 4. There were no significant differences on the each scale between arthrogenous and combitnation group and significant correlated with all 6 scales.

Various characteristics of the object being lifted are known to affect the biomechanical, physiological, and psychophysical stresses. The object characteristics to be considered in the design process of lifting tasks are weight, shape, stiffness, and availability of handles and similar coupling devices. In this study, a prototype Polypropylene laminated bag with carrying handles was designed to decrease the physical stress of people who handle these bags. Physiological and psychophysical approaches as well as subjective ratings were applied to evaluate the effects of handles provided on the designed PP laminated bag. Statistical analysis showed that the VO2, heart rate, blood pressure, and Borg-RPE score for PP laminated fertilizer bag with carrying handles were significantly lower than those bags without handles. Moreover, Maximum Acceptable Lifting Endurance Time(MALET) measure, newly developed in this study, for bags with handles was significantly higher than those for bags without handles. It is thus recommended that the various types of bags and boxes be equipped with handles to reduce the musculoskeletal, physiological, psychophysical, and subjective perceived stresses.

Several benefits provided by white clover (Tnifoliurn repens L.) can be elevated as relationship between its morphological and physiological characteristics is clarified. The experiment was done to analyze the relationship between them in the clover with different leaf size. Individual plants of Osceola (large leaf), Grasslands Huia (medium leaf) and Aberystwyth S184 (small leaf) were grown in 15m plastic pot containing a 1:2:1 soil:sand:Promix mixture for 55 days, and then clipped to remove all fully expanded leaves every 7, 14 or 28 days. To measure the cultivar response, plants were sampled for morphological and physiological parameters on the date (0) after final harvest and 1, 3, 7, 14 and 28 days after the final harvest and then their relationship was analyzed. Osceola had greater leaf area per trifoliolate but less no. of leaves per plant to result in similar total leaf area per plant of all cltivars. Stolon length and no. of growing tips per plant declined with smaller leaf size although the result in biomass was reverse. Stolon of all cultivars showed the greatest fluctuation in total nonstructud carbohydrate during the regrowing period but nitrogen concentrations of all their fractions and dinitrogen fixation did similar patterns. Stolon and root of Osceola, moreover, were the highest ones. Biomass, stolon length and total leaf area per plant of all cultivars were positively correlated to carbohydrate concentration of all frauions and dinitrogen fixation. In Osceola relationship between nitrogen concentration of stolon and the characters showed in Osceola was positively done.

Automated greenhouse production systems often require crop growth monitoring involving accurate quantification of plant physiological properties. Conventional methods are usually burdensome, inaccurate, and harmful to crops. A thermal image analysis system can accomplish rapid and accurate measurements of physiological-property changes of stressed crops. In this research a thermal imaging system was used to measure the leaf-temperature changes of several crops according to water deficit. Thermal images were obtained from lettuce, cucumber, pepper, and chinese cabbage plants. Results showed that there were significant differences in the temperature of stressed plants and non-stressed plants. The temperature differences between these two group of plants were 0.7 to 3$^{\circ}C$ according to species.

This paper is the study of the reflectance of light from biological tissue for red and Infrared wavelengths and relates the acquired reflectance data to expected physiological changes within the skin and muscle layers associated with heat and exercise. The instrument was disigned to collect data from the calf muscle in human subjects with probe located at the surface of skin. Rapid data acquisition method allowed monitoring of rapid changes in reflecttance due to a stimulus. This study demonstrates that changes in O2 saturation and blood fractional volume expected within the dermis and muscle layers were asserted by examining the slopes of the plotted index for heat and exercise. The results presented in thls study support the claim that reflectance can separately discriminate between changes of blood volume and oxygenation in muscle and in skin. The data demonstrate the ability to measure consistent changes In tissue optical properties during exercise and heat.

Hypocotyl segments of shade-grown soybean sprouts(var. Kumdo) were floated in solutions of various substances at physiological levels and grown for either 24 hours at 28$^{\circ}C$ or 72 hours at $25^{\circ}C$. Increased length of the segments beyond 20mm (the original length) was obtained as a measure of the present studies. At the room temperature, Ca and DNP strongly inhibited elongation of the hypocotyl segments, whereas K, IAA, GA and EDTA in general promoted it. There were, however, no such differences in the effects at relatiely low temperature. This indicated that the elongation process not only involves stretching of wall materials, but also does synthesis of the materials. Ca was found to be antagonistic to the promotive action of GA in the elongation, and the IAA action involves metabolic energy. EDTA seemed to act as a widely known chelator removing Ca already existed in the hypocotyl tissue, thus shwoed a promotion in the elongation.

A measurement of conduction veloctiy of the action potentials along the muscle fibres has been applied to various diagnosis. When we measure muscle fiber conduction velocity, it occurs that not only change of conduction velocity but alos inclusion of mipulse component by physiological and experimental reason. So, robuster time delay estimation algorithm than general methods[1] is needed to find correct time delay form these signals. In this paper we, propose new time delay estimation algorithms, robust in impulsive noise, by using characteristic of .alpha.-stable distribution whcih defines impulsive noise well. Then we apply proposed algorthms to measure muscle fiber conduction velocity and compare them with other studies.
