Two experiments were conducted to studs the effects of early-life feed restriction, ages and duration on compensatory growth, feed efficiency, and abdominal fat pad deposition in broilers. The chicks were randomly assigned to four treatments (experiment 1) or seven treatments (experiment 2) . Each dietary treatment was replicated with three floor pens in both experiments, and twenty chicks were assigned to each pen. In experiment 1, birds in control group (C) were full-fed throughout the study. For treatments 1, 2, and 3, bards were fed diets containing 0.75 kcal ME/gB $W^{o.67}$/d for 3 d(T1), 1.5 ㎉ ME/gB $W^{o.67}$/d for 5 d (T2), and 2.25 local ME/gB $W^{0.67}$/d for 7 d (T3), all imposed beginning at 7 d of age. The selected value seems appropriate for maintenance feeding because the feed restriction at T1 resulted no growth in virtually. Although the birds previously subjected with restricted feeding significantly (P<0.05) enhanced growth partly (in 22~49 d), the weight gain over the entire growth period (7-49 d) was not influenced by the restricted feeding Programs. Whereas, the restricted feedings had effects with significant (P<0.75) increase in feed intake not only in 22~49 d, but in overall period (7-49 d). The feed conversion for the birds previously subjected with restricted feeding was significantly (P<0.05) improved after 21 d. The birds with restricted feedings (T1,T2,T3) showed better (P<0.05) feed conversion ratio than C both in 22-49 d and in 7-49 d. The restricted feeding programs did not show effects in reducing for abdominal fat pad deposition or mortality In experiment 2, the birds of C were full-fed in overall period. But for treatments 1, 2, 3, 4, 5, and 6 (T1-T6),the birds were fed diets containing 0.75 ㎉ ME/gB $W^{0.67}$/d for 3 or 5 d, starting at either 4, 7 or 10 d of age. The selected value seems appropriate for maintenance feeding because the feed restriction resulted no growth in virtually; which was same as experiment.

The Korean government's recent large-scale termination and modification of welfare benefits revealed a procedural problem under the National Basic Living Security Act. Under the Act, welfare recipients have a legal right to make complaints only after the termination or modification is enforced; the Act fails to provide the recipients with an opportunity for a hearing before termination or modification, and this creates serious threats to the recipients, whose livelihoods are dependent on welfare benefits. Korean jurisprudence has adopted the due process of law principle. The principle originated from the due process in US jurisprudence, and Korea has applied it broadly to any government actions that restrict individuals' constitutional or legal rights. This paper reviews the termination or modification procedure under the Act with the lens of the due process principle and criticizes that the current law is not in compliance with the principle. In supporting that such termination and modification procedure infringes on welfare recipients' protected rights, this paper discusses two theories as to what rights are protected. First, termination or modification of welfare benefits can be considered as deprivation of property. The 'property' theory may be weak under Korean jurisprudence, because the concept of property under the Korean Constitution is narrowly construed. Second, this paper relies on the constitutional provision that recognizes "the right to a life worthy of human beings," which requires the State to guarantee minimum standard of living for all. As welfare recipients are deemed to receive benefits as a right under the Constitution, any deviation from the minimum requirement would constitute a violation of constitutional rights. In any case, termination or modification of welfare benefits that are concretized under the Act should be protected under the due process principle, because the principle would cover any government actions that restrict established legal rights. This paper argues that the procedural due process requires the recipients be guaranteed an opportunity to have a hearing before the termination or modification is enforced. An independent decision-maker should hear the proceedings, and the recipients should have an option to orally present their opinions in front of the decision-maker. The hearing process under the Administrative Procedures Act of Korea offers elements that would satisfy these procedural requirements. Thus, this paper concludes that the National Basic Living Security Act should be amended to adopt the hearing process under the Administrative Procedures Act in its termination and modification procedure.

This experiment was conducted to evaluate effects of various periods of rye silage feeding on the growth performance, blood characteristics, and carcass quality of finishing pigs. A total of sixteen [($Landrace{\times}Yorkshire{\times}Duroc$)] pigs (90.26 kg in average initial body weight) were tested in individual cages for a 30 day period. Dietary treatments included 1) CON (basal diet), 2) S10 (basal diet for 20 days and 3% rye silage for 10 days) 3) S20 (basal diet for 10 days and 3% rye silage for 20 days) and 4) S30 (3% rye silage for 30 days). There were no significant differences in the ADG and gain/feed ratio among the treatments(p>0.05), however the ADFI was higher in pigs fed the CON diet than with pigs fed diets with rye silage (p<0.05). The DM digestibility was higher with the S20 diet than with the S30 diet (p<0.05). With regard to blood characteristics, pigs fed rye silage had a significantly reduced cortisol concentration compared to pigs fed the CON diet (p<0.05). The backfat thickness was higher with the CON diet than with the S20 or S30 diets (p<0.05). Regarding the fatty acid contents of the leans, the C18:0 and total SFA were significantly higher with the CON diet than with the other diets (p<0.05). However, the C18:1n9, total MUFA and UFA/SFA levels were significantly lower with the CON diet than the other diets (p<0.05). Regarding the fatty acid contents of fat, the levels of C18:1n9 and MUFA were similar with the S20 and S30 diets, however, these levels were higher than with the CON or S10 diets (p<0.05). In conclusion, feed intake and DM digestibility were affected by rye silage, and the cortisol concentration, backfat thickness and fatty acid composition of pork were positively affected by feeding pigs rye silage.

Since a 13% dietary protein level is generally accepted as a standard in evaluating net protein utilization values of protein sources in chicks, limiting amino acids a 13% protein basal diet containing 15% isolated soy-protein as the only source of dietary protein, were identified. Of such amino acids as methionine, lysine, threonine and tryptophan added to the basal diet singly or as a combination, methionine appeared as the only limiting amino acid for optimum growth of the chicks. When the requirement of total sulfur-containing acids (TSAA) was estimated as the point at which the dose-response curve intersected a line representing the plateau for maximum performance, the TSAA requirements for maximum growth and feed intake were 4.73% and 3.73% of dietary protein, respectively. The values, expressed in terms of TSAA intake, required for maximum weight gain, feed intake and gain/feed ratio were 167.1, 136.8 and 159.1 mg/bird/day, respectively.

This experiment was conducted to investigate the feed value of Phellinus linteus meal. The chemical composition and particle size of Phellinus linteus meal was determined, and investigated the effect of partial substitution(0, 5, 10 and 20%) of dried Phellinus linteus meal on metabolizability and serum IgG concentration of layers. Crude fiber content of Phellinus linteus meal was higher, and crude protein and crude fat contents were similar level compare to corn, barley, and wheat. Dry matter metabolizability of Phellinus linteus meal was lower in 10 and 20% treatment than those of 0 and 5% treatment significantly(p<0.05). But, Phellinus linteus meal did not affect concentration of serum IgG.

This experiment was conducted to investigate the effect of restricted feeding to pullet on growth and laying Performance, egg qualify and endocrine Profile in brown layers. 1,080 brown-layer chicks divided to three diet treatments, conventional diet and two restricted diets, for 70 weeks. Conventional diets(C) was formulated by NRC recommendation, and one of restricted diet started from seven to seventeen week of age(T1), and another started from twelve to seventeen(T2) with adjusted eighty percentage amount of conventional diet. Body weight decreased with starting restriction of feeding comparing to the C(P＜0.05), but reached to similar weight in all treatments at twenty week regardless restriction. All of birds started to lay egg around 1,400 to 1,450gram of body weight though the age was in order of C, T2 and T1. Overall e99 Production was the highest in T1 (P＜0.05) and there were not difference in C and T2. Average egg weight also showed similar to the tendency of egg production. Feed intake was higher in T1 during maximum production(P＜0.05), but there were not difference in all treatments after the peak. Overall feed conversion ratio improved in T1 compared to C and T1(p＜0.05). Restriction feeding in rearing period could be beneficial to improve egg productivity and to decrease feed cost.

The objective of this study was to investigate the effect of restricted feeding to pullet on growth and endocrine profile in layers(Isa brown). One thousand eighty brown-layer chicks were divided into three treatments; conventional feeding(ad libitum) and two restricted feedings(80% of conventional diet) for 70 weeks. One of restricted feeding started from seven to seventeen weeks of age, and the other started from twelve to seventeen weeks of age. Diets were formulated by NRC(1994) recommendation. Body weight and feed intake were measured every two weeks, and body composition and organ weight analyzed every week in rearing period and every eight weeks in laying period. Blood was collected at weighing body weight and was analyzed for the concentration of insulin-like growth factor-Ⅰand estradiol. Body weight and feed intake decreased as restriction of feeding begins comparing to ad libitum group(P<0.05), but reached to similar body weight and feed intake at 20 wk of age regardless of restriction. There were no significant differences in development of digestive tract and attached organs among the treatment groups. During rearing period, however, they were slightly higher in restricted group which was low in body weight. In terms of body composition, fat contents of restricted group were significantly lower(P<0.05) than that of ad libitum group around 1,000 grams of body weight. High concentration of IGF-Ⅰwas observed.

This paper review about the relationship between the prohibition against medical refusal and the principle of private autonomy in medical contracts. The obligation to this Prohibition in Medical Law does not restrict the liberty of contracting a medical contract. On the other hand, the prohibition limits the freedom to terminate medical contracts. Medical contracts can be terminated if the trust between doctors and patients is vanished. However certain restrictions should be placed on termination of the medical contract, because termination of the contract should not be detrimental to patients' health. According to the current medical law the medical contract is to be enforced in principle and can be revoked only with justifiable reason. At the Civil Code on Medical Contracts the freedom to terminate the medical contract is permitted, but this paper suggests the restrictions of the revocation under certain conditions. The Criminal Punishment Regulations against medical refusal should be removed. Refusal the provide medical service should be regulated by administrative sanctions under the National Health Insurance Act's obligation.
