This paper describes that the improved effects on the ignition limit are studied by parallel safety components for propane-air 5.25vol.% mixture gas in low voltage inductive circuits. The experimental devices are used in the IEC type spark ignition test apparatus. The improved effects on the ignition limit are respectively obtained as the maximum rising rate of 650%, 1,080% by composing parallel circuits between inductance and safety components (condenser and diode) as compared with disconnecting inductance with the safety components. The more values of inductance the higher improved effects of ignition limit rise. This improving method for the ignition limit is not concerned with the safety components. Diode appears to effect greatly better than condenser. It is considered that the result can be used for not only data for researches and development of intrinsically safe explosion-proof machines which are applied equipment and detectors used in hazardous areas but also for data for its equipment tests.

This paper describes the minimum ignition limits for propane-air 5.25 Vol.% mixture gases in low voltage inductive circiuts. The improved effects on the ignition limit are studied by parallel safety components(resistors) for propane-air 5.25 Vol.% mixture gas in low voltage inductive circuits. The experimental devices used in this test are the IEC type spark ignition test apparatus. The minimum ignition limits are controlled by the values of current in inductive circuit. Energy supplied from electric source is first accumulated at the inductance, it's extra energy is working as ignition source of the explosive gas. The improved effects on the ignition limit are respectively obtained as the maximum rising rate of 330% by composing parallel circuits between inductance and resistor as compared with disconnecting inductance with the safety components. The more values of inductance increase the higher improved effects of ignition limit rise. The less values of resistor the higher improved effects of ignition limit rise. It is considered that the result can be used for not only data for researches and development of intrinsically safe explosion-proof machines which are applied equipment and detectors used in dangerous areas but also for datum for its equipment tests.

I estimate the non-market effects of implementing five-day workweek controlling for the individual-job fixed effect. I find that the implementation of five-day workweek has improved an individual's subjective health status, increased the frequency of exercises, increased the probability to get education or training other than job training, improved subjective quality of life, increased spending for leisure and cultural activities, and improved an individual's satisfaction with the job and the employer. Much of the effects are due to reduction not of working hours but of working days.

Application of growth promoters by means of implantation or supplementation to the diets has been routine in the beef cattle industry of many countries for the better performance in growth and improvement of feed efficiency. Anabolic implants (zeranol, trenbolone acetate, and estradiol with testosterone or progesterone) have generated various positive effects. Zeranol implantation, in general, improved average daily gain (ADG), feed conversion (FC), dressing percentage (DP) and yield grade (YG) of cattle, and increased dry matter intake (DMI). Trenbolone acetate with or without estradiol also increased mean values of ADG and loin eye area (LEA) but reduced DMI and improved FC of cattle. Estradiol with testosterone or progesterone increased ADG and DMI. Anabolic implants, however, had minimal or negative effects on marbling or quality grade. The magnitude of the response to these anabolic implants in performance of beef cattle has varied depending on the type of implants, amount and duration of exposure, age of animals and combination of implants. Administration of bovine somatotropin improved ADG and FC, and decreased fat deposition. Ionophores improved FC in cattle from reduced DMI without great response to ADG. Supplementation of monensin and lasalocid reduced molar proportion of propionate. Monensin and lysocellin increased apparent absorption and retention of some minerals in cattle. Despite the improved cattle performance in growth and FC, results in beef quality from the application of the growth promoters appeared to vary or in conflict under a variety of environmental conditions.

The purpose of this study was to investigate the effects of home exercise program on the improvement of balance in the elderly. Subjects were twenty members living in Daegu (10 males, 10 females), between 65 and 81 years of age. The subjects for the experimental group were participated in the home exercise program for 8 weeks, between April 2001 and June 2001. The results of this study were as follows: After the exercise program, balance ability by CTSIB in the experiment group improved with no statistical significance. On the other hand, balance ability by OLST was significantly improved in the condition with open eyes than dosed eyes. Balance ability by OLSTR was improved 37.2% (p<0.001) on the hard surface with open eyes and improved 41.1% (p<0.01) on the soft surface with open eyes. Balance ability by OLSTL improved 37.1% (p<0.001) on the hard surface with open eyes and improved 72.5% (p<0.001) on the soft surface with open eyes. Balance ability by BBT also improved 1.7% (p<0.05).

Background: This study aimed to investigate the effects of Oenanthe javanica (OJ) extracts on rats with potassium oxonate (PO)-induced hyperuricemia. Methods: The effects of OJ extract on rats with PO-induced hyperuricemia-induced were monitored. Changes in the body weight and organ indices of hyperuricemic rats were calculated to detect anti-hyperuricemic effects. Blood samples were collected to observe the effect of reducing serum uric acid concentration. Kidney tissues were stained to observe histopathological changes under a microscope. The activity of xanthine oxidase (XO), which catalyzes xanthine to uric acid in the liver, was assessed to observe the inhibitory effect of XO. Results: 1. The body weight of hyperuricemic rats showed no considerable differences between the control group and the treatment group. The OJ group had significantly improved liver index, whereas the allopurinol group had improved liver and kidney indices. 2. Serum uric acid levels increased significantly after PO injection, and the OJ and allopurinol groups showed a significant reduction effect. 3. PO injection led to the inflammation of kidney tissues, and OJ improved it significantly. 4. The activity of XO after PO injection was significantly increased, and allopurinol significantly inhibited XO activity in the liver. Conclusion: In the hyperuricemia rat model, OJ extract reduced uric acid concentration and demonstrated its anti-inflammatory effects. Thus, OJ extracts can be used to lower uric acid levels.

Purpose: The major side effects of treatment with oxcarbazepine (OXC) are skin rash and hyponatremia. Hematologic side effects are reported rarely. The aim of this study was to investigate the rate and types of the hematologic side effects of OXC. Methods: The medical records of 184 patients diagnosed with epilepsy or movement disorder and on OXC monotherapy, at the Department of Pediatrics of Inje University Sanggye Paik Hospital from July 2001 to July 2018, were retrospectively reviewed. Results: Of the 184 patients, 10 (5.4%) developed leukopenia in addition to pancytopenia and 2 (1.0%) developed pancytopenia. Leukopenia developed in 11 days to 14 years after OXC administration and was more frequent in males than in females (male vs. female, 9 vs. 1; Fisher exact test, P<0.05). Of the eight patients with leukopenia alone, 7 continued OXC treatment; 6 improved without intervention; 1 was lost to follow-up; and 1 received a reduced OXC dose, who improved after intervention. Pancytopenia developed within 2 months of initiation of OXC treatment. Both patients initially continued OXC. One improved within 1 month and continued treatment with OXC, but the other showed progression of the side effect, leading to the discontinuation of OXC and subsequent improvement within 1 month. There were no significant differences in the ages of the patients, OXC dose, and duration of OXC treatment between patients with and without these side effects of OXC (P>0.05, t-test). Conclusion: OXC-induced leukopenia is not rare and may result in pancytopenia. Patients being treated with OXC should be regularly monitored for abnormal complete blood count profiles.
