  • Purpose: The purpose of this study was to identify the entity of critical care nursing practices through analyzing nursing statements described by electronic nursing records in a MICU. Methods: 176,459 nursing statements of 188 patients during a 6 month-stay were analyzed statement by statement according to the nursing process(nursing phenomena, nursing diagnosis, & nursing activity) and 21 nursing components of Saba's Clinical Care Classification. Results: Among 176,459 single statements, the statements of nursing activity ranked first in number. The contents of the statements were analyzed and categorized by main themes. Among 489 categorized themes, the number of themes of nursing phenomena statements was the highest. When analyzed by Saba's clinical Care Classification, the nursing statements mainly included a physiological component. Among 21 components, the respiratory component ranked in the first position in nursing phenomena, nursing diagnosis and nursing activity. The extra statements not included in the 21 components were 9,294(15.1%) in nursing phenomena and 21,949(22.7%) in nursing activity. Most are statements related to tests and the doctor. Conclusion: The entity of MICU nursing practice expressed by electronic nursing records was mainly focused on physiological components and more precisely on respiratory components.

  • Even one embryonic myocardial cell exhibits a spontaneous, periodic beating phenomena. When these cells come in contact with each other, they beat synchronously with a certain period. In this paper, the mechanism of this phenomena is investigated, and the synchronization model is presented. The physiological experimental results are compared with the simulated results of the model.

  • Currently, the signal of the human body is measured with various methods, and a noninvasive investigation of various methods is useful diagnosis method. PTT(Pulse Transit Time) which is noninvasive investigation make use of to estimate the physiological phenomena. PTT has a latent information of cardiovascular system. So we have the experiments for analysis of the relations between PTT and physiological parameters. We examine to correlate to the physiological parameters, an age and degree of paralysis on the ultrasound therapy. The 40 patients who has a such paralysis join our experiment, and we obtain the PTT data that normal condition and states after ultrasound therapy. We study that PTT after the ultrasound therapy for patients who have a paralysis was related to an age and degree of paralysis.

  • 본 시험은 신품종인 유신을 공시하여 실소와 가리의 시비수준을 달리하고 출수후 차광처리를 하여 급성위고현상의 발생을 재현시고, 위고현상의 발생과 식물체내 무기성분의 함양 및 근의 생리적 활역과의 관련성을 명백히 함과 동시에 1976년에 전국적으로 .유신품종에 대발생한 위고현상과 1977년에 전혀 발생이 없었던 기상적인 요인을 비교 검토하여 위고현상의 발생요인을 구명코자 실시하였다. 그 결과를 요약하면 다음과 같다. 1. 유신품종은 실소증비에 의해 엽신중당 영화수 (Sink/source)가 현저히 증가하고, 상위절간에 비해 하위절간의 신장률이 뚜렷한 품종적인 특징이 있다. 2. 유신품종은 실업증비에 따라 엽신의 호흡양이 타품종에 비해 현저히 증대하는 특성이 있음을 인정 할 수 있었다. 3. 위고극다비( $N_{30}$, $K_{10)}$ 하에서 근발육과 근의 생리적 활력이 저하했으며, 실소극다비+차광처리에서 더욱 현저한 저하를 보였다. 4. 또한 실고극다비+차광처리는 도체내 엽초와 간내의 K_2 O함량을 저하시키고, 특히 간내 K_2O/N 비 및 탄수화물의 함량을 명백히 저하시켰다. 5. 유신의 위고현상은 실소극다비구에서 경미하게 발생하였고, 실고극다비+차광에서 50 % 처리구에서 격심한 발생을 유발 재현시킬 수 있었다. 6. 본 시험결과로 미루어 1976년에 대발생한 유신의 급성위고현상은 도작기간 일사양이 현저히 부족했던 기상적인 요인이 주요인이며, 농민의 실소과잉시용이 위고현상을 조장하는 부요인으로 해석되었다.

  • The periodicity of the physiological flow has been the major interest of analytic research in this field up to now Among the mechanical forces stimulating the biochemical reaction of endothelial cells on the wall, the wall shear stresses show the strongest effect to the biochemical product. The objective of present study is to find the effects of velocity waveform on the wall shear stresses and pressure distribution along the artery and to present some correlation of the velocity waveform with the clinical observations. In order to investigate the complex flow phenomena in the bifurcated tube, constitutive equations, which are suitable to describe the rheological properties of the non-Newtonian fluids, are determined, and pulsatile momemtum equations are solved by the finite volume prediction. The results show that pressure and wall shear stresses are related to the velocity waveform of the physiological flow and the blood viscosity. And the variational tendency of the wall shear stresses along the flow direction is very similar to the applied sinusoidal and physiological velocity waveforms, but the stress values are quite different depending on the local region. Under the sinusoidal velocity waveform, a Newtonian fluid and blood show big differences in velocity. pressure, and wall shear stress as a function of time, but the differences under the physiological velocity waveform are negligibly small.

  • Common usage of the concept of juvenility implies that there is one physiological phase, the juvenile phase, which manifests itself in the various morphological and physiological phenomena observed in juvenile higher plants. The juvenile phase is often defined as that time from seed germination until the plant attains the ability to flower regulating such behaviour. This definition precludes plants from flowering in the juvenile phase. It is of major interest, therefore, to identify the physiological controls(Bluehreife) regulating such behavior. The length of the juvenile period in higher plants ranges from one year to over 60 years in different species. The long juvenile period of seedling is the main cause of the long duration of the breeding process. I determined the length of the juvenile period in various plants and its control of phase changes in natural system in relation to factors such as plant size and age, shoot morphology, apex size, root system and phytohormonal and nutritional status is reviewed. From the own experimental and observational evidence available it appears that both hormonal and nutritional factors can be involved in control of juvenility but that a specific juvenile or flowering hormone is not involved. Grafting, ringing, scoring, root pruning and fertilization have been used to accelerate flowering, but in most cases these cultured treatments are only successful on plants that were passed the juvenile phase. It is suggested that there are intrinsic difference between the meristematic cells of the apieces of juvenile and adult shoot, which are thus determined with respect to there development potentialities. The problems associated with the maintenance of the determined state through mitosis are discussed. The properties of transitional forms of Ribes nigrum L. intermediate between the juvenile and adult phase, are descrived and there implications discussed. Analogies are drawn between juvenile phenomena in woody perennials and in herbaceous species.

  • Physiological observations reported and the perceptual phenomena that some simple arrays of discrete dots are perceived as a continuous curve, and others are perceived as an angular contour or as consisting of separate goups of dots. The perception of continuous curves versus discondinuous angles is mainly determined by the relative orientations of the dots, i.e., by the angles between sucessive virtual lines, whereas the length of the virtual lines gives little influence. It is important that the perception of dot stimuli is presented by vitual lines between dots in visual information processing. In this paper, on the basis of these facts of physiological observations, some experimental results on the perception of visual lines form dot stimuli are shown. Triples of the dots used in the experiment are similar to those of smith & Vos' physiological experiments.

  • Formation of nutrient qi is one of the most important functions in the human body. In medical classic such as "Hwangdineijing", it is described through several chapters. However, it is just focused on the first formation of the nutrient qi from water and food by digestion. I will mention how to get nutrient qi in human body and how to circulate and act in physiological phenomena through "Hwangdineijing". Human body should get nutrient qi from essense not only from water and food. Human body, because it is a live, must have had a nutrient material before he or she gets water and food by formation of nutrient qi. So he or she can have physiological functions.

  • Managerial intuition is a well-recognized cognitive ability but still poorly understood for the purpose of developing effective decision support systems. this research investigates whether the differences in accuracy of "time series forecasting" are related to the differences in one's cognitive style, using statistical test The hypotheses established in the research model did not have positive correlation The lack of correlation between "cognitive style and physiological measures" and accuracy in forecasting may be caused by uncontrolled external variable. Thus, further analyses on physiological characteristics and brainwaves are needed. The approaches such as neural network and data mining are proposed.

  • This research aims is to study physiolgy and pathology of lung on Suenbal-Sukkang action occuring with the exchang of Metal and Fire of nature. The exchange of Metal and Fire(金火交易) represents differience of temperature inside and outside of the atmosphere in according to Sun-heat on earth descended in passing Hazi(夏至). On the above fact, the Suenbal-Sukkang( action representing the Exchang of Metal and Fire happens in lung of body with properties of metal. too. These phenomena are physiological phenomenas of Pulmonary series(肺系). Accordingly, the action of Suenbal-Sukkang radiates heat and converge water with the properties of Autumn-Metals in change actions of nature. In order To interpret physiology action of Pulmonary energy(肺氣), I have studied Metal-glass theory(金鏡說) of Muk Za(墨子), and made a comparative study of a climatic change passing from summer to autumn in four season caused by the revolution of earth Thus, to interpret the action of Suenbal-Sukkang can be inferred by the phenomena of physiology and pathology of Pulmonary series. From the result of this study, I know that functions representing of the Suenbal-Sukkang take place in processing the exchange of Metal become phenomena in physiology of Pulmonary series(大腸, 皮膚, 鼻, …), and abnormal functions functions representing the Suenbal-Sukkang become pathological phenomenas of Pulmonary series.
