Coronoid impingement can cause limitation of mouth opening. In many cases, it appears to be related to the coronoid hyperplasia. We present a case of mouth opening limitation caused by coronoid impingement on the posterior surface of the zygomatic bone without coronoid hyperplasia. The bony changes in coronoid and zygoma including surface irregularity and discontinuity of the cortex and sclerotic change of inner medullary space were noted on computed tomography (CT) scans in different level of axial planes. Through another CT scans in open mouth position could demonstrate that those bony changes were caused by the contact of both surfaces against each other. In case coronoid impingement is suspected of the many possible causes, the open mouth CT scans will be needed to reveal the direct impingement of coronoid on zygoma even without coronoid hyperplasia.

Background and Objectives : Digital rectal examination (DRE) and uroflowmetry have been usually together in the BPH management. The aim of this study was to determine whether DRE would affect uroflowmetry measurement. Materials and methods : A total of 80 male patients were included in this study. First uroflowmetry was done after DRE, second uroflowmetry was done without DRE. Third uroflowmetry was done after DRE, and fourth was done without DRE. Results : The mean Qmax on uroflowmetry after DRE was 15.2±8.7㎖/sec and 14.9±9.8㎖/sec. The mean Qmax on only uroflowmetry was 15.3±8.9㎖/sec and 15.4±8.4㎖/sec. There was statistically no difference between the mean Qmax(P> 0.05). And effect of digital rectal examination on uroflowmetry measurement with age was statistically no difference between the mean Qmax(P)0.05). Conclusions : We could not find and effect of DRE on uroflowmetry parameters, In this study, uroflowmetry test would be appropiate for recommending DRE before or after.

The purposes of this study were 1) to investigate the effect of blood lactate disappearance during maximal exercise load and recovery; 2) to deteermine changes of blood lactate concentrations during incremental maximal exercise for the training and non-training groups; 3) to estimate changes of chrdiopulmonary function during exercise and recovery; 4) to analyze changes of plasma epinephrine, and norepinephrine during exercise and recovery. The subjects of this study consist of a total of 16 young adult women with a mean age of 22.1 year (7 basketball athletes and 9 women students) who are following at Physical Education department in S womens universilty. Incremental maximal exercise load test and active recovery (Vo2max40%) and passive recovery after Vo2max 100% were conducted on the treadmill three times at a week interval. 1.The results of this study indicated that with increasing time of exercise during the same intensity of exercises oxygen uptake was significanatly「(P<.05) higher in non-training group than training group. However, oxygen uptake was high in training group(52.34±9.87ml/kg/min) compare to non-training group(46.07±7.01ml/kg/min) at the level of all-out exorcise. 2.Respiratory exchange ratio at 10min absolute maximal exercise load was significantly high(P<.05) in non-training group(0.95 ±0.05) compare to training group(0.90± 0.05). 3.Hear rate at rest, during exercise, and recovery was high in non-training group compare to training group. Especially significant difference(p<.05) could be observde in heart rate between training(148.6±18.3beats/min, 175.0± 12.7beats/min) and non-training groups(164.1 ± 18.3bents/min. 189± 10. 1beats/min) at 6 and 10 min exercise. 4.Ventilation volume increased with increasing title and intensity of exercise and there was no difference between training and non-training groups. 5.Blood lactate concentrations during 6,8, 10, and 12 min of incremental maximal exercise load were significantly (p<.05) low in training group(1.51 ±0.41mM/l, 1.830mM/l. 1.84±0.37mM/l, 3.11 ± 0.33mM/l) compare to non-training group(2.28±0.51mM/l, 3.09±0.50mM/l. 4.85± 1.16mM/l. 6.09 ±0.99mM/1). 6.Blood lacate concentrations at recovery after a brief period of maximal exertcise load was found to be significantly low (p<.01) in trainging group compare to non-training group. 7.Recove rate of blood lactate aftar a brief period of maximal exercise load was significantly high(p<.05) in active recovery method(88.25± 10.85%. 76.30± 14.67%) compare to passive recovery method(42.41 ±8.93%, 46.69± 13.50%). 8.There was no significant change in plasma epinephrine for training 76.27±14.67pg/ml, 60.76±34.53pg/ml and non-training 72.37±23.46pg/ml, 77.10±28.58pg/ml groups at passive and active recovery after a brief period of maximal exercise load. However, plasma epinephring was significantly low(p<.05) in training group compare to non-training group. 9.There was no significant change in plasma norepinephrine for training (232.34±33.16pg/ml, 263.51±93.25pg/ml) and non-training(244.37±91.87pg/ml, 244.97±47.44pg/ml) groups at passive and active recovery after a brief of period of maximal exercise load. However, no significant difference was found in plasma norepinephrine between training antral non-training groups. 10.There were no differences in epinephrine and norepinephrine after a brief period of maximal exercise load for active(271.48±72.16pg/ml, 297.96± 101.21pg/ml) and passive recovery(271.70±81.28pg/ml, 311.69±109.38pg/ml) respectively. 11.No relationships could be observed between epinephrine and norepinephrine concentrations and maximal capillary blood locate values after a brief period of maximal exercise load. In conclusion, blood lactate concentrations were significantly low in training group after maximal exercise load compare to non-training group. Recovery of blood lactate concentration after exercise was also faster in training group compared to non-training group. Especially, active recovery at rest was found to be more effective blood lactate disappearance. There were no changes in catecholamine after a brief period of maximal exercise load. Catecholamine concentrations were not affected by recovery method and it did not show to be influenced by blood lactate concentrations.

Korea has made great progress in anthracite producing capacity since past decade. Neverthless its promotion is critically desired and has become one of the great concerns of the government in carrying out the present national economic development plan because of shortage in our energy resources. Increase of anthracite production results from cooperation between management and labor instead of useless and excessive labor disputes. In this article has been dealt with real conditions and improvement ways of Labor-Management cooperation of coal mining corporations in Yong Dong Area only. To point out some of them to be considered and examined, are as follows. Firstly, in Collective Bargaining, labor union's organization being prerequisite to it should be induced to all the coal mining enterprise, its organization activity should be trained and the operative labor union law needs to be amended so that employees may have the right to reqire nationwide collective bargainning. Furthermore, it is desirable to adopt minimum wage system and widen span of collective barginning to workers' participation in management. Secondly, in Consultation of Labor-Management, even the labor union unformed enterprise should have the duty to organize a consultation instrument between employers and empoyees, moreover the existing consultation meeting should be strengthened effectively to actualize workers' participation in management. Lastly, in view of social welfare for workers. prompt enforcement of minimum wage system, investment inducement to welfare facilities by the government and the enterprise concerned, and widening application of existing workers' compensation insurance will be needed. The true labor-management harmony is contribute not only to increase of coal production capacity, but to just distribution of business performance through democratization of industry.
