무제한 급수하면 저에너지 사료를 섭취하는 닭은 모자란 에너지의 보충을 위해 사료를 더 많이 섭취하여 에너지의 제한 효과가거의 없었고 제한급수하면 사료를 충분히 섭취할 수 없기 때문에 대조구의 약 70$\%$밖에 섭취못했다. 따라서 이것이 성성숙을 4$\~$4 1/2주 지연시킨 요인이었으며 체지방 축적도 감소시켰다. 성성숙 지연결과 성숙이 지연된 닭은 총 산란수가 훨씬 많고 비정상란의 수가 훨씬 적으며 대란율도 훨씬 높다. 육성중 폐사율은 더운 여름철에도 급수의 제한과 상관없었으며 산란중 폐사율은 오히려 성성숙시의 체중 혹은 체지방 축적과 정비례 했다. 이상으로 저에너지 사료를 급여하면서 급수제한(격일제 급수)하는 방법이 대추의 에너지 섭취를 제한시키는 간단하고 효과적인 방법임이 입증되었다.

The current study was undertaken to determine the prolinged effects of fasting-refecding on the lipoprotein lipase (LPL) activity and lipogenesis of adipose tissus in male Sprague-Dawley rals and to investigate the effects of various degrecs of food restriction during refeeding on the LPL activity and lipogenesis. The control group (n=5) was fed ad libitum and killed in the fed state at the beginning of the experiment. All rats except conteol group were fasted for 2 days (n=50). Five rats were killed at the end of fasting and others (n=45) were refed either ad libitum (ad libitum group) or mildly restricted (20% food restricted group), or esverely restricted diet (40% food restricted group). Rats were killed on the day of 7th, 14th, and 21st of refeeding. Lipogenesis was determined by the amount of glucose converted to the total lipid. Body weight and epididymal adipose tissue weight returned to control states by 5 days in ad libitym group and by 14 days in 20% food restricted group. As expected, in 40% food restriction during refeeding weight and epididymal adipose tissue weight did not rcturn to control states until day 21. On day 21 after refeeding, the serum total cholesterol concentration of ad libitum group was significantly (p<0.05) higher than that of control group. The serum HDL-C concentration of 40% food restricted group during refeeding was significantly (p<0.05) higher than that of control group. However, there were no significant dif-ferences in serum HDL-C/total cholesterol (TC) ratio and trigluceride concentration among the groups. Fasting for 2 days decreased lipogenesis and LPL activity (p<0.05). On day 21 after refecding, the lipogencsis of ad libitum group was significantly (p<0.05) lower than that of control group. The lipogenesis of 40% food restricted group during refeeding was significantly (p<0.05) higher than that of conrtol group. Ad libitum group and 20% food restricted group during refecding allowed heparin-releasable (HR) LPL or total extractable (TE) LPL activity to return to control states. 40% food restricted group during refeeding delayed the return of HR-LOL or TE-LPL activity to return to control states until day 21 of refeeding. These results suggest that food restriction during refeeding can partially or completely prevent the overshoot of LPL activity, and this may influence the rate of lipid accumulation in adipose tissue during refeeding.

Korea paid attention to the work injury insurance in the early economic development stage as other developed countries did. Thus "The industrial Accident Compensation Insurance Law" was legislated in 1963 and it is now expanded to apply to the workplace with five or more employees. Beside the low coverage of the number of employees, the scope of benefits are the problem of work injury insurance. The work injury insurance's main benefits are for the loss of income and the medical cost caused by occupational accidents. On the other hand, the investment on the prevention accident and the medical, social and employment rehabilitation is very low, even though the occupational accident pension is higher than that in other OECD countries. Practically lay-off benefits and survivor' benefit for some special workers are paid more than they need, therefore they want to remain under the benefit condition and the medical care days are longer. This paper indicates the problems of work injury insurance and suggest how to improve the functions of it.

This study analyzed the current status of MRI (frequency, amount of treatment) based on the history of application of the MRI health insurance benefit standard and health insurance claim data. MRI examinations began as a health insurance benefit in 2005. In 2005, the indications were restricted for some diseases, but coverage for benefits in 2010, 2013, 2016, and 2018 was expanded. In 2021, the Ministry of Health and Welfare decided to apply health insurance for all MRI examinations. From 2010 to 2017, the number of MRI examinations increased by 86.7% in 2017 compared to 2010, and the amount of treatment increased by 53.5%. According to general characteristics, the number of MRI examinations was higher in women than in men. By age, the number of examinations was the highest among ages 70-79. Outpatient examinations were more frequent than inpatient examinations, and the number of examinations in the tertiary hospitals was the highest among the types of hospitals. The number of brain MRI examinations was the highest in each exam site. In December 2013, the standard of MRI was expanded for heart disease and Crohn's disease, the number of cardiac MRI and abdominal MRI examinations increased in 2014 compared to 2013. However, the number of examinations is small and not associate with the disease, it would be difficult to say that it affected the increase in the total number of MRI examinations. To assess health insurance sustainability and policy effectiveness, monitoring will be necessary.

In order to investigate an effect of the feed restriction on the laying performance, 208 White Leghorn strain layer of 36 week-old were divided to 4 groups of 52 birds each and raised for 1 week of previous feeding and for the subsequent 3 weeks of experimental restricted feeding. The egg production, daily egg mass and feed efficiency of four groups of birds fed daily 100g, 95g, 90f and 85g of a commercial diet, respectively, which were compared with those of the original 2879 birds fed l13g of diet per day as control. During 3 weeks of experimental restricted feeding, period, daily body weight nam was decreased linearly as the degree of restriction increased in birds fed 100, 95, 90 and 85g of diet. Hen day egg production, egg weight and daily egg mass was linearly related to the diet intake level. then feed intake(x, g day$^{-1}$ ) showed a positive regression equations with the henday egg production(y, % ), egg weight(y, g egg$^{-1}$ ) and egg mass(y, g bird$^{-1}$ ) as y＝38.75＋0.3753$\times$(r＝0.503, n＝15), y＝48.2＋0.08868$\times$(r＝0.835, n＝ 15) and y＝15.69＋0.2786$\times$(r＝0.597, n＝15), respectively. Feed efficiency was increased to a plateau in birds fed 95g of diet. The estimated energy utilization for egg production was reached to a plateau in birds fed 95g of diet and the highst protein utilization was shown in birds fed 90g of diet anions birds fed graded levels of diet. And the feed restriction did not affect on the egg shell contents, while protein contents of egg were shown a trend to be increased and lipids and cholesterol contents of eggs was decreased according to the diet intake lowered. The results suggested that the improved feed efficiencies of birds restricted under 16% of diet(above 95g of diet) will be due to increased energy and protein utilization for egg production and feed restriction above 16% will be aboided. In the range from 113g to 95g of diet feeding, the crude profit was increased as the feed restricted in the case of egg price 600 won kg$^{-1}$ and feed price 200 won kg$^{-1}$ .

This study was conducted to investigate the effects of Aspergillus niger-derived multi-enzyme complex supplementation to feedrestricted lactating sows on performances, milk yield, blood profiles, and manure excretion as compared with ad libitum-fed sows without supplementation of enzyme. Fifty multiparous lactating Berkshire sows were allotted to 5 treatments of 10 sows per treatment during a 28-d lactation period and litter per sow was standardized to 9 suckling piglets. Treatments were ad libitum-fed sows without enzyme and feed-restricted sows supplemented with four increasing levels (0, 0.02, 0.04 and 0.08%) of multi-enzyme complex derived from Aspergillus niger. Blood samples from all sows were collected to determine serum metabolite concentrations before the morning feeding on d 27 of lactation. Litter body weight and a piglet weight at weaning, and litter weight gain significantly (P<0.05) increased with increasing levels of multi-enzyme complex, but there was no significant difference between ad libitum-fed sows without enzyme and feed-restricted sows supplemented with multi-enzyme complex. Body condition score and backfat depth at weaning significantly (P<0.05) increased as multi-enzyme complex level increased. Lactational backfat depth tended (P>0.05) to less decrease with increasing levels of enzyme complex. Serum inorganic phosphorus and non-esterified fatty acid concentrations significantly (P<0.05) increased with increasing levels of enzyme complex. Daily milk yield was not significantly different across treatments, but milk fat yield significantly (P<0.05) increased as multi-enzyme complex level increased. Manure output was significantly (P<0.01) higher for ad libitum-fed sows than for feed-restricted sows, but there was no significant difference among feed-restricted sows supplemented with increasing levels of multi-enzyme complex. Fecal phosphorus amount significantly (P<0.05) decreased with increasing levels of multi-enzyme complex. Feed costs of sows per litter weight gain were reduced by 1.25% to 9.67% with increasing levels of multi-enzyme complex as compared with ad libitum-fed sows without enzyme. The results indicated that multi-enzyme supplementation to feed-restricted lactating sows not only increased litter performances, but also was comparable to ad libitum-fed sows, resulting in reduced feed costs. Moreover, the reduction of fecal phosphorus amount with increasing levels of enzyme complex would contribute to the reduction of environmental pollution.

This study was conducted to evaluate the effects of feeding rye silage and feed restriction on both growth and reproductive performances in replacing gilts. Twenty four replacing gilts (Landrace×Yorkshire, 67.63±1.17kg initial BW) were used in 49 d growth assay. Dietary treatments were included 1) CON(basal diet), 2) S15(15% feed restriction + ad libitum rye silage) and 3) S30(30% feed restriction + ad libitum rye silage). In growth performance, average daily gain and average daily feed intake were the highest in CON among treatments(P<0.05). Average daily silage intake was not significantly different between S15 and S30 treatments(P>0.05). Feed conversion ratio was the lowest in CON among treatments(P<0.05). Average silage intake of S15 and S30 treatments was increased as time goes by(P<0.05). While all gilts of S15 and S30 treatments became pregnant, one gilt of CON became pregnant. Also, first estrus and mating were occured earlier in S15 and S30 than those of CON. In conclusion, 15% feed restriction and feeding rye silage reduced growth performance, reached earlier to first estrus and increased pregnancy rate in replacing gilts.
