With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

단체행위모형에 관한 고찰

We have developed a formal model of collective action which brings together features associated in particular with the work of Elster, Schelling and Akerlof. We would argue that the model is capable of application to a wide range of empirical contexts involving issues of collective action where the free-rider problem renders conventional economic analysis inadequate. The approach offers insights into the historical development of such groups as trade unions and could be empirically tested against such processes. As Hardin(1982) has shown the results obtained here can carry over from the issue of collective action to that of the multi-person prisoner's dilemma. A number of aspects of the model deserve further development. Here we indicate two such aspects. First, we have treated the ε^1 distribution as determined exogenously. Alternatively, we could follow Jones(1984) and make our ε^1 parameter endogenous within the model. One way of doint this would be to make ε^1 itself dependent upon the individual's decision with respect to membership of collective action. Or we could think of the individual as influenced by a vector of social norms with his/her attitude to each affected throughεi by his/her behavior with respect to the others. Second, we have abstracted from the economic structure or game in which the collective action is, or is not, taking place. Clearly, a complete model needs to specify the interactions between the economic parameters and social custom inuluences on collective action. We have tried this elsewhere for the issue of trade union membership and wage determination(see Naylor(1989)) but do not pursue this here as any particularisation is likely to be context-specific.

In this paper, we propose a remote controller for robot manipulators using local area network(LAN) and internet. To do this, we develop a sever-client system as used in the network field. The client system is an any computer in a remote place for the user to log-in the server and manage the remote factory. The sever system is a computer which controls the manipultor and waits for an access from a client. The server system consists of several control algorithms which is needed to drive the manipulator and networking system to transfer images that show the states of work place, and to receive a job data to run the manipulator. The client system consists of a 3D(dimension) graphic user interface for the teaching and off-line tasks like simulations, and external hardware interface which makes iy easier for the user to teach it. Using this server-client system, the user who is in remote place can edit the work schedule of the manipulator, then run the machine after it is transferred and monitor the results of the task.

Background : Cardiac arrest is a potent stimulus for the release of endogenous catecholamine and high plasma catecholamine concentration has been reported during cardiopulmonary resuscitation(CPR). Few data were present about the clinical effect of high plasma catecholamine and endogenous catecholamine response to exogenous epinephrine administration during CPR. Purpose : This study was designed to evaluate endogenous catecholamine response to cardiac arrest and exogenously administered epinephrine during CPR. Method : In 21 cardiac arrest victims, blood sample for epinephrine and norepinephrine was drawn before and 1 minute after each epinephrine administration during CPR. 1mg of epinephrine was administered immediately after intravenous access and 3 minute interval during CPR. Plasma catecholamines were quantitated by high-performance liquid chromatography. Result : Baseline plasma epinephrine concentraqtion was higher in patients with cardiac arrest than normal controls (985±1627 vs 194±173 pg/ml, p<0.05). Baseline plasma norepinephrine concentration was also elevated in patients with cardiac arrest than normal controls, although statistically insignificnat(1965±4915 vs 360±250 pg/ml). Plasma epinephrine concentration in cardiac arrest patients was significantly elevated after exogenous administration of epinephrine, but its response was blunted after the third does of epinephrine. Plasma norepinephrine concentration in cardiac arrest patients was also elevated, but its response was observed only after the first epinephrine administration. Plasma epinephrine concentration was persistently higher in patients with return of spontaneous circulation (ROSC) than patients without ROSC. there was no significant difference of plasma norepinephrine concentration whether spontaneous circulation was restored or not. Endogenous epinephrine response to exogenous epinephrine was not observed in patients having prolonged arrest time over 20 minutes. Conclusion : Results of this study suggests that significant amount of catecholamine is released by exogenous epinephrine administration in spite of high plasma catecholamine concentration, and degree of endogenous catecholamine response influences resuscitation outcome.

쑥 양침액의 투여와 관련된 변화를 관찰한 결과, 전 시험기간을 통해 단회투여 후 14일 동안 일반증상, 치사율, 체중변화, 부검소견, 장기중량변화, 혈청생화학적 분석등의 각종 지표에 의한 안전성을 평가했을 때 1× 실험군에서는 대조군에 비해 유의한 변화를 관찰할 수 없었으며 10×쑥약침액 투여 후 관찰된 체중의 감소, 혈정생화학적 수치의 유의한 변화는 과용량의 시험물질에 의한 영향으로 생각된다. 한편, 5×, 10×의 쑥약침액을 투여한 실험군에서 활동력 저하, 호흡수 감소, 졸음 및 무기력등의 임상증상이 관찰되었는데 이는 중추신경계 억압에 의한 증상으로 보고??되어 있다. 또한, 혈액내 혈청을 분리하여 간세포 이상의 지표로 사용하고 있는 GOT, GPT를 측정하였고 혈청 중의 total enzyme을 측정하여 LDH의 활성치를 계산, 이것을 심폐질환, 혈액질환, 간질환의 유무를 알아내는 지표로 사용하였으며 간염, 간경변, 골질환의 유무를 알아내는 지표로 사용하는 ALP-s를 측정하였다. 농도에 따른 쑥 약침액의 영향을 알아본 결과 쑥 약침액을 대조군에 비하여 단회투여시 1×의 농도에서는 대조군에 비해 유의한 차이를 나타내지 않았으나 5×, 10×의 농도의 실험군에서는 상당히 유의한 차이를 나타냄으로써 쑥 약침액의 과용량의 투여는 마우스의 간세포, 골세포, 심폐기관 등에 유해작용을 일으킬수 있음을 알 수 있었다. 본 실험을 통해 1×의 쑥 약침액의 용량은 급성 독성시험 결과 무해한 용량으로 판단되며, 5×이하의 용량군을 세밀히 나누어 검토할 필요가 있다고 판단된다. Acute toxicity of Artemisia Nakai Aqua-acupuncture Solution(ANAS) as studied in ICR mice. Mice were injected inrtapeitoneally with single dose of 1×, 5×, 10× ANAS and toxicological responeses were observed for consecutive 14 days. Mortality, clinical signs, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with 1× and 5× ANAS were not affected during the experimental periods. With the 10? ANAS treatment, dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. There results suggest that 1× ANAS causes no toxicity that 10× ANAS causes toxicity in acute toxicity test.

A new dynamic control algorithm for the position control of robot manipulators is proposed. This algorithm consists of an open loop control and a closed loop control. The former is a recursive Newton-Euler algorithm of the desired trajectory, and the latter is a VSS type control. The important role of an open loop control is the compensation of nonlinear dynamic couplings among joints in order to reduce the lower bound of gains of a closed loop control. This algorithm is robust to the modelling inaccuracies, parameter errors and the change of payload. Moreover, this algorithm requires very short calculation time. Numerical Simulation of a three-link manipulator is presented to show the robustness and applicability.

기업 총리스크지수(TRI) 모델의 개발과 측정

김경수,김종년 成均館大學校 韓國産業硏究所 2002 韓國經濟 Vol.29 No.-

As economic uncertainty increases, the financial risk for enterprises is spreading. Based upon these economic situations, this paper proposes a model for measuring the enterprise risk. This model is named TRI(Total Risk Index), which consists of six sectors; financial indicator risk, real price risk, competition risk, customer risk, finance policy risk, and operation risk. The risk of financial institutions can be measured through VaR(Value-at-Risk). But non-financial institutions such as manufacturing companies can possess various types of risk, so this risk can be measured through TRI. The result of measuring TRI for Korea representative enterprises shows that their TRI comprises half of their own capital. This result signifies that the enterprise risk is high. This model can be utilized as Early Warning System for non-financial companies through historically measuring TRI.
