The purpose of this study was to identify and compare Health Promoting Behavior and its affecting factors between Normal and Over weight industrial middle manager. The subjects were 163 workers employed in factories in Taegu and Kyung-book were convenient sampling data the period for May 22th-26th, 2000 through self report methodby structured questionnaires. Collected data were analyzed by t, x2, Kendal tau, Pearson correlation, Stepwise Multiple Regression. The results of this study were as follows. 1. There were a significant difference in shift pattern(x2=7.89, P=0.005) and career. (x2=12.99, P=0.005) between normal weight and overweight group. 2. The average score of performance in health promoting behavior among overweight group(2.55) was higher than that of normal weight group(2.46), but not significant. 3. The average score of health status in overweight group(3.07) was lower than that of normal weight group(3.21), but not significant. 4. The average score of self-efficacy in overweight group(3.63) was significant lower than that of normal group(3.71). 5. The average score of the perceived barrier of in overweight group(2.44) was significant higher than that of normal group(2.24). 6. Health promoting behaviors in overweight group was significantly correlated with health status(r=.384, P<.05), health Concept(r= 458, P<.01) self-efficacy ( r=352, P< 01), perceived benefit(r=.386, P< .05), perceived barrier(r= -245, P< .05) Health promoting behavior in normal weight group was significantly correlated with health concept( r= .307, P< .050 and perceived benefit. 7. In consideration of variables that have an influence on Health promoting behavior among Normal weight group, health concept and perceived benefit account for 28.8% of health promoting behavior. In overweight group. The perceived benefit account for 13.7% of health promoting behavior. The suggestions are as follows on the basis of the results of this study. 1. It is required to develop health promoting program to improve health promoting behavior. In addition, there are special demands on developing nursing strategies for health promoting behavior of overweight industrial supervisors. 2. It is necessary to support exercise facility in occupational field for improving supervisor's health promoting behavior.

An equation is developed to estimate potential groundwater resources available for development. This equation is useful for planning generally conducted prior to detailed design. The equation is a function of major factors such as aquifer characteristics, saltwater intrusion length, coastalgroundwater discharge and location of proposed pumping wells. Therefore, the equation is quite comprehensive. The equations are derived using well-known analytical solutions. Thus, the basis is scientifically sound. Use of the equation is quite simple since it is an explicit function of variables. A logical method is proposed to assess a radius of influence of a pumping well considering aquifer characteristics and pumping rate. Applications to a hypothetical problem and comparison with results from a more rigorous numerical simulation model indicatethat results obtained from the proposed equation are conservative.

The solvent extraction to separate and recover cobalt and nickel from sulfuric acid solution was studied using Cyanex 272 in kerosene. The solution processed was equivalent to that expected from leaching of a matte, intermediate product of manganese nodules. The extraction of both metals increased with increasing equilibrium pH and extractant concentration. However, cobalt was preferentially extracted over nickel. The extraction efficiencies of cobalt and nickel were 80% and 1.9% respectively with 0.2M Cyanex and O/A of 1 at equilibrium pH 5.0. The separation factor of Co/Ni increased with raising the extraction temperature (205 at 20℃, and at 441 at 50℃). The saponification of Cynanex 272 increased the extraction of cobalt due to the increase of equilibrium pH. Nickel (0.40 g/l) loaded in an organic phase could be scrubbed with a solution containing 10 g/l Co at equilibrium pH of 6.0. The stage numbers and cobalt recoveries in extraction and stripping processes required for the counter current operations are predicted using the equilibrium isotherm plots. (Received May 19, 2004)

당뇨병환자에서 자율신경 기능장애를 알아내기 위한 검사로서 심호기 심흡기율이 건강인에 비해 떨어져 있음을 심전도를 이용하여 검사하므로서 환자 침대에서 간단하게 그리고 정확하게 검사할 수 있었다. 당뇨병환자는 안정시 정상인에 비해 빈맥이 있으며, 심박수의 감소 또한 유의하게 적었다. 특히 건반사가 이상이 있는 당뇨병환자에서 건반사가 정상인 환자에 비해 심박수의 변화가 유의하게 적었으며 건반사가 이상인 환자에서 심흡기 심호기율이 1.10 이하는 56명중 49명으로 88%나 되었다. Retinopathy가 있는 환자에서 역시 심박수의 변화는 유의하게 적었고 심흡기 심호기 율이 1.10 이하인 예가 47명중 38명으로 78%나 되었다. 또한 단백뇨가 있는 환자에서도 심박수의 변화는 그 정도는 낮았으나 유의하게 적었다. 당뇨병의 병력기간이 길수록 심흡기 심호기율은 더 작아지는 경향은 확실하며 저자의 예에서는 병력기간이 1년이상 5년이하까지는 1.11±0.21 이였고, 5년이 넘어서서 10년 이하에서 1.07±0.03으로 1.10을 하회(下廻)하였다. 이와 같은 성적으로 미루어 보아 심호흡시 흡기 호기의 율을 계산함으로써 외과수술환자의 급성심폐부전에 의한 높은 사망율을 줄이는 데는 많은 도움이 될 것이다. To find a simple and accurate test of autonomic nervous dysfunction in diabetes mellitus, we performed maximal deep breathing procedures while undergoing electrocardiographic recording at bed side. Normal indivisuals at rest show variation in heart rate induced by respiration. During maximal deep breathing these changes are accelltuated and electrocardiographic recording will show the increase in heart rate during inspiration and the decrease during expiration. This variation is reduced or abscent in diabetics with autonomic neuropathy. Forty eight of the 56 with sensory neuropathy(88%) had an DE/Dl ratio below of 1.10. Diabetics with retinopathy also had significantly smallest variation and thirthy eight of the 47 with retinopathy(78%) had an DE/DI ratio below of 1.10. Also diabetics with proteinuria had significantly smaller variation. Relation between duration of diabetics and DE/DI ratio was inverse proportion accurately. For example in diabeticc of duration which above 1 year and below 5 years DE/DI ratio was 1.11±0.21 and in diabtiecs with below 10 years duration was 1.07±0.03. Our study cleary shows that diabetics with sensory neuropathy have a high prevalence of autonomic dysfunction, with may be important clinically. Since sudden cardiorespiratory deaths are common in diabetics with autonomic neuropathy during and after sugery, the determination of the DE/DI ratio might be a suitable preoperative test for those diabetics at risk. Patients with an abnormal ratio should probably be closely monitered in an intensive care unit after operation.

The purpose of this study was to evaluate the bone age and hand anomaly in Down syndrome patients. We reviewed radiographs in 52 children and youths with Down syndrome, aged from 2 to 23 years. The characteristic findings of hand anomaly were observed in the middle phalanx of the fifth finger, with the following incidence; brachymesophalangia(44%), clinodactyly(48%), and dysmesophalangia(15%). Pseudoepiphysis(21%) was found typically at the distal end of the first metacarpal bone and proximal end of the second metacarpal bone. Up to 8.5 years of age, bone maturation was retarded and thereafter bone age accelarated in advance of chronologic age. These findings may provide valuable information relative to the diagnosis and treatment of hand anomaly in Down syndrome.

We had a result of the treatment as below when is devided Korean medicine Tx.. Western medical Tx., Cooperative Tx.. 1) At the improvement of BP control, an average in Korean medicine Tx. (from 170㎜Hg/100㎜Hg to 150㎜Hg/90㎜Hg), an average in Western medical Tr. (from 170㎜Hg/100㎜Hg to 130㎜Hg/80㎜Hg), an average in Cooperative Tx.(from 180㎜Hg/110㎜Hg to 130㎜Hg/90㎜Hg), generally all pars had improvements of BP control. But it is not significant of each case. 2) At the improvement of symptoms by the apologetics, Cooperative Tx. is profitable in cases of 'GanHwa',' DamEum', 'EumYangYangHer', 'EumHer'. Korean medicine Tx. is superior in case of 'GiChe'. 3) At the improvement of symptoms by a questionnaire, Korean medical Tx., Western medical Tx., Cooperative Tx. groups had improvements, but each practice group didn't have specific significance. Only it was somewhat profitable to Korean medical Tx. in the 210㎜Hg/110㎜Hg, Western medical Tx. in the 180㎜Hg/110㎜Hg, Cooperative Tx, in the 170㎜Hg/90㎜ Hg. 4) There are the apparent improvements in patients whose BP are over 200㎜Hg of Korean medical Tx. group, whose BP are over 190㎜Hg of Western medical Tx. group and whose BP are over 170㎜Mg of Cooperative Tx. group. There are the improvement of diastolic BP in 110㎜Mg(Korean medical Tx., Western medical Tx.) and 90㎜Hg(Cooperative Tx.). 5) At the improvement of Pulse pressure, generally Pulse pressure are decreased. There are similar improvements in all of Korean medical Tx., Western medical Tx., and Cooperative Tx.. 6) At the Symptomatic approvement according to ages, Korean medical Tx., Cooperative Tx. are somewhat good for his twentieth, and Western medical Tx. is somewhat good for his forties. 7) the correlation of Obesity-grade and BP, as Obesity-grade is higher as BP is higher, but there are no similarity in the improvement. 8) At the EAV improvements, as examination into correlation with the point of 1~3th, we could get results as below. There are high improvements of DRHTM, DRALM, DLLYM, DLLIM in Cooperative Tx. There are high improvements of DRPASI, DLLARI in the Korean medical Tx. group. There are high improvements of DRFADM in Western medical Tx. group.
