Main control room(MCR) man-machine interface(MMI) design of advanced nuclear power plants(NPPs) such as APR(advanced power reactor)-1400 can be validated through performance-based tests to determine whether it acceptably supports safe operation of the plant. In this work, plant performance, personnel task, situation awareness, workload, teamwork, and anthropometric/physiological factor are considered as factors for the human performance evaluation. For development of measures in each of the factors, techniques generally used in various industries and empirically proven to be useful are adopted as main measures and some helpful techniques are developed in order to complement the main measures. Also the development of the measures is addressed based on the theoretical background. Finally we discuss the way in which the measures can be effectively integrated and then HUPESS(HUman Performance Evaluation Support System) which is in development based on the integrated way is briefly introduced.

The goats raised in the barn are usually fed on fresh grass. As dry forage can be stored for long periods in large amounts, dry forage feeding makes it possible to feed large numbers of goats in barns. This review explains the physiological factors involved in suppressing dry forage intake and the cause of drinking following dry forage feeding. Ruminants consume an enormous amount of dry forage in a short time. Eating rates of dry forage rapidly decreased in the first 40 min of feeding and subsequently declined gradually to low states in the remaining time of the feeding period. Saliva in large-type goats is secreted in large volume during the first hour after the commencement of dry forage feeding. It was elucidated that the marked suppression of dry forage intake during the first hour was caused by a feeding-induced hypovolemia and the loss of $NaHCO_3$ due to excessive salivation during the initial stages of dry forage feeding. On the other hand, it was indicated that the marked decrease in feed intake observed in the second hour of the 2 h feeding period was related to ruminal distension caused by the feed consumed and the copious amount of saliva secreted during dry forage feeding. In addition, results indicate that the marked decreases in dry forage intake after 40 min of feeding are caused by increases in plasma osmolality and subsequent thirst sensations produced by dry forage feeding. After 40 min of the 2 h dry forage feeding period, the feed salt content is absorbed into the rumen and plasma osmolality increases. The combined effects of ruminal distension and increased plasma osmolality accounted for 77.6% of the suppression of dry forage intake 40 min after the start of dry forage feeding. The results indicate that ruminal distension and increased plasma osmolality are the main physiological factors in suppression of dry forage intake in large-type goats. There was very little drinking behavior observed during the first hour of the 2 h feeding period most water consumption occurring in the second hour. The cause of this thirst sensation during the second hour of dry forage feeding period was not hypovolemia brought about by excessive salivation, but rather increases in plasma osmolality due to the ruminal absorption of salt from the consumed feed. This suggests the water intake following dry forage feeding is determined by the level of salt content in the feed.

This study was conducted to investigate the effect of temperature during transportation and continuing shelf-life on fruit quality and the occurrence of physiological disorder to set up the appropriate exportation temperature condition in Asian pear (Pyrus pyrifolia Nakai) 'Hanareum'. In the experiment of simulated exportation headed for USA, the fruits transported at $1^{\circ}C$ showed less weight loss than those of $5^{\circ}C$. Market temperature appeared as a key factor for keeping freshness of exported pear fruits rather than transportation temperature. Quality factors such as high flesh firmness and low incidence of fruit rot and physiological disorders including core breakdown and pithiness were attained at the fruits maintained at $18^{\circ}C$. Approximately two times higher incidence of physiological disorders and of fruit decay rates were observed in the fruits distributed at $25^{\circ}C$ than the those of $18^{\circ}C$. Therefore, temperature management during marketing resulted as an important factor for maintaining fruits quality in the process of pear fruit exportation.

Normal balance is defined as state in which the body is equlilibrium. It is complex motor control task, requring integration of sensory information, neural processing, and biomechanical factors. There are major two factors contribute to balance control, the neurological and the musculoskeletal. The neurological factor provides the sensory processing and motor output mechanisms that are the neurophysiological basis for response. The musculoskeletal factor provides the mechanical structure for response. When all components of two factors are operating effectively, the postural response should be appropriate and effective for good balance control. Therfore, balance can be influenced by above all factors. In addition, balance can be also influenced by muscle tone, hearing, physiological factors, and environmental factors. Physical therapists must understand factors of balance control so that we can accurately assess balance. Therefore, physical therapists have to develop useful balance measurement tools to evaluate balance.

A new quantitative method was developed for separation of three interactive physiological factors (hepatic glucose balance, peripheral tissue's insulin resistivity, and insulin secretion rate) influencing glucose intolerance in diabetic mellitus using an equivalent circuit model and the intravenous glucose tolerance test (IVGTT) in six dogs and twenty two humans. The results show that the estimated model parameters of the above three factors are useful for evaluating different glucose-insulin kinetics in normal and diabetic subjects.

The ultra-high definition TV system nicknamed "Super Hi-Vision" is a television system with 4000-scanning-line video and 22.2 multichannel sound. NHK has been developing it with the aim of creating a broadcasting system conveying a strong sensation of presence. We believe that it is important to design the system by taking into account human factors such as human visual system characteristics. This paper describes the psychological and physiological experiments on the visual effects of "Super Hi-Vision".

The Purpose of this study is to extend the understanding and knowledge of menopause by comparing menopausal symptoms of married women and nuns in order to improve health and the quality of life for women. In this study a questionnaires were distributed to 116 nuns and 121 married women, from forty to fifty nine years old in Daegu metropolitan city. This study used the measurement of menopausal symptoms (Cronbach's Alpha=0.96) corrected and complemented by this student with consideration of various literature centered around menopausal symptoms, suggested by Janette M. Perz as 51 questions including 4 realms; [mental psychological factors], [physical physiological factors], [eyesight factors], and [urinary generative factors] in order to measure the degree of menopausal symptoms. The results are as follows : 1. There was a significant difference between educational background, religion, occupation, leisure time, satisfaction of marriage or ascetic life, existence of hormonal treatment, name of medical operation, and existence of counselling about menstruation as general and physiological characteristics of the nuns' group and the married women's group. 2. The menopausal symptoms of the nuns' group and the married women's group according to order in which they were presented were; 'feeling tired and lacking in energy(1.71 points)' 'vision not clear or clouded(1.69 points)', and 'be forgetful (1.57 points)' in nuns' group. 'be forgetful (1.87 points)', 'vision not clear or clouded(1.83 points)' and 'feeling tired and lacking in energy(1.76 points)' in the married women's group. The symptoms which showed the highest rank of menopausal symptoms had a maximum score of 4 points. 3. There was a statistical a significance (t=-3.9807, p<.0001) between the two groups which showed, on an average, 57.92 points in the married women's group and 43.03 points in the nuns' group from 0 to 196 of the possible points of menopausal symptoms. In difference of menopausal symptoms by menstrual aspect of the nuns' group and the married women's group, there was statistically significant difference between the two groups, showing 44.81±26.07 score in the nuns' group and 72.33±35.29 score in the married women's group as the mean score of the groups with no menstruation(t=-4.1132, p=0.0001). 4. The differences in menopausal symptoms with respect to the general and physiological characteristics of the nuns' group and the married women's group were that the nuns' group showed less menopausal symptoms on all the items than that of the married women's group. Finally, in these results, the married women's group showed higher menopausal symptoms than that of the nuns' group. Especially as the score of menopausal symptoms since the climacteric was very high it is confirmed to be a new phenomenon. Accordingly, it is considered to be necessary to carry out an indepth study of the factors related to establishing a strategy for nursing service.
