Objective: This study investigated the effect of fermented biogas residue (FBR) of wheat on the performance, serum biochemical parameters, and meat quality in pigs. Methods: We selected 128 pigs (the mean initial body weight was $40.24{\pm}3.08kg$) and randomly allocated them to 4 groups (1 control group and 3 treatment groups) with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received a corn-soybean meal-based diet, the treatment group fed diets containing 5%, 10%, and 15% FBR, respectively (abbreviated as FBR5, FBR10, and FBR15, respectively). Every group received equivalent-energy and nitrogen diets. The test lasted 60 days and was divided into early and late stages. Blood and carcass samples were obtained on 60 d. Meat quality was collected from two pigs per pen. Results: During the late stage, the average daily feed intake and average daily gain of the treatment groups was greater than that of the control group (p<0.05). During the entire experiment, the average daily gain of the treatment groups was higher than that of the control group (p<0.05). Fermented biomass residue did not significantly affect serum biochemical parameters or meat quality, but did affect amino acid profiles in pork. The contents of Asp, Arg, Tyr, Phe, Leu, Thr, Ser, Lys, Pro, Ala, essential amino acids, non-essential amino acids, and total amino acids in pork of FBR5 and FBR10 were greater than those of the control group (p<0.05). Conclusion: These combined results suggest that feeding FBR could increase the average daily gain and average daily feed intake in pigs and the content of several flavor-promoting amino acids.

Oxytetracycline, tetracycline, chlortetracycline and doxycycline in honey were separated by solid phase extraction (SPE) and determined with high performance liquid chromatography (HPLC) with UV/Visible detector. Analysis was carried out using following conditions: XTerra $C_8$ column $(3.9\times150mm\;i.d. 5{\mu}m)$, mobile phase composed of 0.01M oxalic acid : methanol : acetonitrile (820 : 80 : 100, v/v/v), isocratic pump at a flow rate of 0.9 ml/min. and $50{\mu}l$ of injection volume, UV/Visible detector with wavelength of 360nm. The calibration curves of four tetracyclines showed linearity $(\gamma^2>0.999)$ at concentration range of $100\~1,000 ng/ml$. The recoveries in fortified honey represented more than $70\%$ with low coefficient of variation $(<10\%)$ for concentration range of four tetracyclines. The detection limits for oxytetracycline, tetracycline, chlortetracycline and doxycycline were 13.8, 14.6, 26.2 and 24.9ng/g in acacia honey. respectively. We also monitored tetracyclines residue in domestic honey [n : 38, acacia (20), wild flower (18) ] and foreign honey [n=22, legally distributed (13), illegally distributed (9)] using modified Charm II screening and HPLC confirmation methods. Seven of the 60 samples $(11.7\%)$ were suspect positive using modified Charm II screening test. Chlortetracycline residue was found in one foreign honey (illegally distributed) tested at concentrations of 0.22 ppm. Conclusively, for more effective control of tetracyclines used in beekeeping should be further survey for residues in honey and also national guidelines (maximum residue limit : MRL) and methods should be obligatory.

국내 유망 수출 식품 중 잔류농약으로 인하여 수출 장애가 있는 식품을 대상으로 문제가 되는 농약에 대해 CAC 및 수출국의 농약잔류 허용기준 제안을 위한 작물잔류 시험을 수행하였다. 대상 작물은 수출용 단감이었고, difenoconazole과 thiamethoxam을 대상으로 시험을 수행하였다. Difenoconazole의 잔류량 범위는 0.2~0.56 mg/kg였고, thiamethoxam의 잔류량 범위는 0.08~0.28 mg/kg으로 두 약제 모두 수확 1일차 시료부터 MRL 농도 이하로 잔류량이 감소하였다. 따라서 안전사용기준에 따라 약제를 살포하고 수확한다면 국내에 설정된 MRL 기준을 충분히 만족시키는 것으로 확인되었다. Difenoconazole의 각 포장별 반감기는 각각 13.6, 19.4, 16.3일 이었고, thiamethoxam의 각 포장별 반감기는 각각 10.0, 15.3, 14.0일 이었다. Clothianidin의 잔류농도는 1개 지역에서 14, 28일 시료에서 검출되었으나, 농도는 0.03 mg/kg 이하였다.

The possibility of simultaneous analysis of 24 pesticides out of 30 residual pesticides which are subjected to test in the golf courses was examined. The utility of the simultaneous analysis of multi-residue pesticides was evaluated by recovery test through a standard addition method of pesticides in water, soil, and lawn grass. The experimental results of the recovery rates for individual pesticides are as follows : The number of pesticide of which average recovery was over 70% regardless of medium was 16 pesticides. These pesticides were composed of 8 organophosphorus pesticides(Chlorpyrifos, Chlorpyrifos-methyl, Diazinon, EPN, Fenitrothion, Phenthoate, Phosalone, and Toclofos-methyl). 4 organochlorinated pesticides(Daconil, Captan, Endosulfan, and Tetradifon), 2 pyrethroid pesticides(Fepropathrin, Lambda-cyhalothrin) and 2 other pesticides(Bromopropylate, Pendimethalin). On the other hand, in case of Dicofol, average recovery by medium was over 70% for water and lawn grass but was only 53.3% for soil. Therefore, the simultaneous analytical method applied in this experiment is not appropriate for analysis of Dicofol in soil. Furthermore, among 7 pesticides, 2 pesticides(Amitraz and Pyraclofos) showed that theirs average recovery rates deviated from criteria(70~130%) at almost all media, while 5 pesticides(Bensulide, Deltamethrin, Iprodione, Phosphamidon and Tralomethlin) were not detected from all media by selected GC detector(NPD or ECD).

Benzimidazole is an widely used anthelmintics in livestock clinics. The aim of present study was to investigate benzimidazole residues in the meat in Sejong City. A total of 338 samples of meat(beef 287, pork 37, chicken 14) were selected from the laboratory meat(Korean beef genetic test, hygiene test) supplied to school in Sejong City. Representative benzimidazole class drug such as thiabendazole, 2-amino albendazole sulfone, fenbendazole, oxfendazole, and oxfendazole sulfone were monitored in samples by using lc-ms/ms and the analysis was preformed based on the Korea Food Code guideline. Limit of quantitation (LOQ) was ranged from 0.56 to 3.02 ppb for target drugs and the accuracy was within the acceptance criteria. Among the sample analyzed only one case, the pork meat was found to have drug levels that exceed LOQ. However, the overall residue concentration was 2.17 ppb, which was lower than the maximum residue levels (100 ppb).

In this paper, we adopt a position specific scoring matrix as an abstraction of amino acid type to derive two new statistical potentials for protein structure prediction, and investigated its effect on the quality of the potentials compared to that derived using residue specific amino acid identity. For stringent test of the potential quality, we carried out folding simulations of 91 residue A chain of protein 2gpi, and found unexpectedly that the abstract amino acid type improved the quality of the one-body type statistical potential, but not for the two-body type statistical potential which describes long range interactions. This observation could be effectively used when one develops more accurate potentials for structure prediction, which are usually involved in merging various one-body and many-body potentials.

A method is proposed to predict the distances between given residue pairs (between C$\sub$${\alpha}$/ atoms) of a protein using a sequence to structure mapping by indefinite quadratic approximation. The prediction technique requires a data fitting in three dimensional space with coordinates of the residues of known structured proteins and leads to a numerical ref resentation of 20 amino acids by minimizing a large least norm iteratively. These approximations are used in distance prediction for given residue pairs. Some computational experience on a test set of small proteins from Brookhaven Protein Data Bank are given.
