  • Goat milk production and processing is a dynamic and growing industry that is fundamental to the health of hundreds of millions of people worldwide and is recognized as an important contributor to many national economies. Goat milk has contributed significantly to the economic and nutritional quality of life in developing countries, particularly in the Mediterranean, the Middle East, Eastern Europe, and Latin America. Goat milk has played an important role in the health and nutrition of infants and the elderly, and is also known to be beneficial and therapeutic for people with milk allergies. The potential and value of the nutritional, health, and therapeutic effects of goat milk and specialized goat milk products are now attracting attention. Various products can be made from goat milk based on its chemical properties. In addition, special products such as hair, skin care, products, and cosmetics produced using goat milk have garnered more attention in recent years. Nevertheless, high quality products can only be made from good quality goat milk. Advanced technical treatments are necessary to produce high quality goat milk that meets consumer expectation of nutritional, hygienic, and good sensory products. Good taste has been a critical criterion when deciding to buy and consume goat milk and associated products. However, it may be possible to produce more value-added products that cater to the new trends in consumer needs and thus maintain economic sustainability of goat milk industry.

  • Objective: An experiment was conducted to investigate the effects of different diet formulations: F1 (Two complicated basal diets containing different crude protein levels plus tested feedstuff) vs F2 (A simple corn soybean meal [SBM] basal diet plus tested feedstuff) combined with total collection (TC) or chromic oxide ($Cr_2O_3$) marker or acid-insoluble ash (AIA) marker method, and freeze-dry or oven-dry (OD) technique on estimation of nutrient digestibility in diets fed to growing pigs. Methods: In F1, twelve barrows were allocated to two $6{\times}4$ Youden Squares. The treatment diets included a high protein basal (HPB) diet, a low protein basal (LPB) diet, a corn diet and a wheat bran (WB) diet formulated based on the HPB diet, and a SBM diet and a rapeseed meal (RSM) diet formulated based on the LPB diet. In F2, eight barrows were allocated to two $4{\times}4$ Latin Squares. The treatment diets included a corn basal diet, a SBM basal diet formulated based on the corn diet, and a WB diet and a RSM diet formulated based on the SBM diet. Results: Concentration of digestible (DE) and metabolizable energy (ME), and the apparent total tract digestibility of gross energy, ash, neutral detergent fibre, and acid detergent fibre determined by $Cr_2O_3$ marker method were greater than those determined by TC and AIA marker methods in HPB, LPB, and RSM diets formulated by F1 and in corn diet formulated by F2 (p<0.05). The DE values in WB and both DE and ME values in SBM and RSM estimated using F1 were greater than those estimated using F2 (p<0.05). Conclusion: From the accuracy aspect, the AIA marker or TC method combined with OD technique is recommended for determining the energy concentration and nutrient digestibility of components in diets fed to growing pigs.

  • Objective: Two experiments were conducted to determine the effects of feeding level on nutrient digestibility and enteric methane ($CH_4$) emissions in growing goats and Sika deer. Methods: Three growing male goats (initial body weight [BW] of $22.4{\pm}0.9kg$) and three growing male deer (initial BW of $20.2{\pm}4.8kg$) were each allotted to a respiration-metabolism chamber for an adaptation period of 7 d and a data collection period of 3 d. An experimental diet was offered to each animal at one of three feeding levels (1.5%, 2.0%, and 2.5% of BW) in a $3{\times}3$ Latin square design. The chambers were used for measuring enteric $CH_4$ emission. Results: Nutrient digestibility decreased linearly in goats as feeding level increased, whereas Sika deer digestibility was not affected by feeding level. The enteric production of $CH_4$ expressed as g/kg dry matter intake (DMI), g/kg organic matter intake, and % of gross energy intake decreased linearly with increased feeding level in goats; however, that of Sika deer was not affected by feeding level. Six equations were estimated for predicting the enteric $CH_4$ emission from goats and Sika deer. For goat, equation 1 was found to be of the highest accuracy: $CH_4(g/d)=6.2({\pm}14.1)+10.2({\pm}7.01){\times}DMI(kg/d)+0.0048({\pm}0.0275){\times}dry$ matter digestibility (DMD, g/kg)-0.0070 (${\pm}0.0187$)${\times}$neutral detergent fiber digestibility (NDFD; g/kg). For Sika deer, equation 4 was found to be of the highest accuracy: $CH_4(g/d)=-13.0({\pm}30.8)+29.4({\pm}3.93){\times}DMI(kg/d)+0.046(0.094){\times}DMD(g/kg)-0.0363({\pm}0.0636){\times}NDFD(g/kg)$. Conclusion: Increasing the feeding level increased $CH_4$ production in both goats and Sika deer, and predictive models of enteric $CH_4$ production by goats and Sika deer were estimated.

  • Objective: Two experiments were conducted to determine the effects of forage-to-concentrate (F:C) ratio on the nutrient digestibility and enteric methane ($CH_4$) emission in growing goats and Sika deer. Methods: Three male growing goats (body weight $[BW]=19.0{\pm}0.7kg$) and three male growing deer ($BW=19.3{\pm}1.2kg$) were respectively allotted to a $3{\times}3$ Latin square design with an adaptation period of 7 d and a data collection period of 3 d. Respiration-metabolism chambers were used for measuring the enteric $CH_4$ emission. Treatments of low (25:75), moderate (50:50), and high (73:27) F:C ratios were given to both goats and Sika deer. Results: Dry matter (DM) and organic matter (OM) digestibility decreased linearly with increasing F:C ratio in both goats and Sika deer. In both goats and Sika deer, the $CH_4$ emissions expressed as g/d, g/kg $BW^{0.75}$, % of gross energy intake, g/kg DM intake (DMI), and g/kg OM intake (OMI) decreased linearly as the F:C ratio increased, however, the $CH_4$ emissions expressed as g/kg digested DMI and OMI were not affected by the F:C ratio. Eight equations were derived for predicting the enteric $CH_4$ emission from goats and Sika deer. For goat, equation 1 was found to be of the highest accuracy: $CH_4(g/d)=3.36+4.71{\times}DMI(kg/d)-0.0036{\times}neutral$ detergent fiber concentrate (NDFC,g/kg)+$0.01563{\times}dry$ matter digestibility (DMD,g/kg)-$0.0108{\times}neutral$ detergent fiber digestibility (NDFD, g/kg). For Sika deer, equation 5 was found to be of the highest accuracy: $CH_4(g/d)=66.3+27.7{\times}DMI(kg/d)-5.91{\times}NDFC(g/kg)-7.11{\times}DMD(g/kg)+0.0809{\times}NDFD(g/kg)$. Conclusion: Digested nutrient intake could be considered when determining the $CH_4$ generation factor in goats and Sika deer. Finally, the enteric $CH_4$ prediction model for goats and Sika deer were estimated.

  • South Korea started to actively participate in the ODA project across Asia, Africa, the Middle East, CIS countries, and Latin America as it transitioned from a country receiving developmental aid to a donor country. As more and more recipient countries are looking into the e-government model of South Korea, a new approach to the Korean model is being investigated. Various promotions were made, ranging from the implementation of the e-government ODA project, review of its feasibility to evaluation of the results. In order to improve and maximize performance management OD projects, it is necessary to look into the analysis of its follow-up results. In this study, practical performance management and policy implications were explored, focusing on the e-government ODA project. In particular, a case study analysis was attempted with focus on the Nigerian e-government project promoted as part of the project. It focused on Korea's e-government linkage process, implementation procedures and strategies applied when establishing the e-government master plan and suggested the necessity of an approach suitable for new environmental changes. In terms of sustainability of the ODA project, it is necessary to build a Korean e-government model that reflects the new intelligence information technology.

  • Domestric Construction & Engineering market has been long in recession due to the global economic crisis. Domestic construction industries consequently looks at overseas construction markets where relatively more construction projects are constantly required. In order to provide meaningful information for Korean engineering companies to keep the pace with the changes in the construction industry, various construction related date and statistics are analyzed. In addition, previous research from the related organizations and construction engineering companies are closely reviewed. Investigation of preliminary data and research have been conducted to draw remedies for their overseas expansion. Moreover, it is attempted to classify foreign markets as the Asia, Africa and etc. (Europe, North America/the Pacific and Latin America) to provide the list of first target countries and its regional market information focusing on their bidding system. This study had tried to show comparative analysis of different bidding procedures between Korea and the selected countries to suggest measures of improvements for the domestic bidding system. Finally, this study suggested policy recommendations to meet the requirement of bid qualification to advance the global market that was suggested with validated clustering bidding data.

  • 본 연구는 육성돈에 있어 인분해효소인 phytase의 첨가가 환경친화성사료개발을 위한 기초자료로 사용하기 위해 영양소 이용률을 측정하였다. 대조구는 옥수수-대두박의 육성돈 사료이고, 처리구는 대조구 사료에 Phytase의 첨가 수준을 500 unit 및 1,000 unit을 첨가한 구로 3×3 Latin Square 방법으로 실시하였다. 건물과 질소에 대한 소화율에서는 각 처리구간에 유의적인 차이가 없었다(P>0.05). 회분, 칼슘 및 인의 소화율의 경우 phytase 첨가구가 대조구에 비해 높은 수준을 보였다(P<0.05). 돼지가 섭취한 인의 양은 phytase 첨가구가 대조구에 비해 증가하였다. 또한 인의 흡수량에서 phytase 첨가구가 대조구에 비해 높았다(P<0.05) 분과 뇨의 총 인 배설량은 유의적인 차이를 나타내지 않았다. 칼슘의 섭취량은 처리구가 대조구에 비해 높았다. 칼슘의 분 배설량은 각 처리구간에 별 다른 차이를 보이지 않았으나(P>0.05), 뇨의 배설량은 처리구가 대조구보다 적은 양이 배설되었다. 소화된 아미노산 중 cystine, isoleucine, tyrosine, phenylalanine은 처리구가 대조구에 비해 소화율이 현저히 증가된 것을 알 수 있었다(P<0.05). Asparagine, threonine, serine, methionine, leucine의 경우 phytase를 500 unit 첨가한 구가 높은 소화율을 나타내었다(P<0.05). 한편 lysine, histidine, arginine 등의 다른 아미노산은 처리구가 대조구보다 약간의 소화율 증가를 보였으나 통계적 유의차는 나타나지 않았다(P>0.05). 결론적으로 인분해효소 phytase를 사료내 첨가하므로서 분중 영양소를 줄일 수 있는 환경친화성 사료를 개발 가능하다고 사료된다. 체결홈이 형성된 체결부를 갖는 안경집과 이것에 결합되는 체결구가 마련되어 개폐되는 커버가 형성된 케이스로 구성된다.로 금형설계 및 제작기간을 단축하고자 한다.ere demonstrated in rats after i.c.v., intraperitoneally and orally administration, respectively. The antiepileptical effects by the combination of compounds from ginseng; were compared with the iuluence of Rg1, Rb1, Rc and with the well known antiepileptical drugs such as carbamazepine, valproic acid. The base for the research is obtained by using the WAG/Rij strain (Luijtelaar, Coenen, Kuznetcova), an excellent genetic model for human generalized absence epilepsy. The improving action of gensinosides was effectively demonstrated on the model of electrical kindling of amygdala of WAG/Rij rats with genetically determined absences, and the influences of ginsenosides on the slow wave discharges have also been being investigated. The different characteristics of a kindling process exerted in the sex-dif

  • The bioequivalence of two omeprazole enteric-coated products was evaluated in 16 normal male volunteers (age 26-32 yr, body weight 57-75 kg) following single oral administration. Test product was enteric-coated KD-182 tablet (Chong Kun Dang Corp., Korea) and reference product was $Rosec^{\circledR}$ capsule containing enteric-coated pellets of omeprazole (Yuhan Corp., Korea). Both products contain 20 mg of omeprazole. One tablet or capsule of the test or the reference product was administered to the volunteers, respectively, by randomized two period cross-over study ($2\;{\times}\;2$ Latin square method). Average drug concetrations at each sampling time and pharmacokinetic parameters calculated were not significantly different between two products(p>0.05); the area under the concentrationtime curve to last sampling time (8 hr) $(AUC_{0-8hr})$ $(1946.5{\pm}675.3\;vs\;2018.3{\pm}761.6\;ng{\cdot}hr/ml)$, AUC from time zero to infinite $(AUC_{o-\infty})$ $(2288.6{\pm}1212.8\;vs\;2264.9{\pm}1001.3\;ng{\cdot}hr/ml)$, maximum plasma concentration $(C_{max})$ $(772.5{\pm}283.3\;vs\;925.8{\pm}187.7\;ng/ml)$, time to maximum plasma concentration $(T_{max})$ $(2.38{\pm}1.06\;vs\;2.34{\pm}1.09\;hr)$, apparent elimination rate constant $(k_{\ell})$ $(0.5339{\pm}0.2687\;vs\;0.5769 {\pm}0.2184\;hr^{-I})$, apparent absorption rate constant $(k_a)$ $(1.1536{\pm}0.5278\;vs\;0.9739{\pm}0.9507 hr^{-1})$ and mean residence time (MRT) $(3.13{\pm}0.73\;vs \;3.41{\pm}1.04\;hr)$. The differences of mean $(AUC_{0-8hr})$, $C_{max}$, $T_{max}$ and MRT between the two products (3.69, 19.83, 1.32 and 8.99%, respectively) were less than 20%. The power $(1-{\beta})$ and treatment difference $(\triangle)$ for $AUC_{o-8hr}$ $C_{max}$ and MRT were more than 0.8 and less than 0.2, respectively. Although the power for $T_{max}$ was under 0.8, $T_{max}$ of the two products was not significantly different each other(p>0.05). These results suggest that the bioavailability of KD-182 tablet is not significantly different from that of $Rosec^{\circledR}$ capsule. Therefore, two products are bioequivalent based on the current results.

  • This experiment were conducted to determine the formation of fatty acid soaps, digestibility and ruminal characteristics when vegetable oils were added. Three Corriedale${\times}$ 3 Latin square design. Sheep were fed one of three diets consisting of alfalfa hay and concentrates in a ratio of 70:30. Dietary treatments were 1) no oil, 2) 7% soybean oil and 3) 7% corn oil. At the end of each experimental period, rumen contents from each sheep were collected before feeding and at 1, 3, 6 and 9h after feeding. pH decreased up to the 3 hour after feeding and increased until the end of the collection(p<0.0001). Whereas the concentration of $NH_3$-N showed inverse changes to pH(p<0.0001). Type of oil did not affect the molar concentration of total VFA, acetate, propionate and butyrate. Acetic/propionic acid (A/P) ratio decreased with increasing time(P<0.0001), but the ratio at the end of the experiment became similar to the initial value. No effects were found in the digestibility of dry matter, total-N, crude fiber, ash, NFE, NDF and ADF. The formation of fatty acid soaps(FAS) increased after feeding than 1 hour before feeding(P<0.05) and increased in 7% oils than no oil addition(P<0.05). Long chain fatty acids formed mainly FAS. ince the formation of FAS might decrease negative effects on ruminal haracteristics and total tract digestibility.

  • A novel in situ-gelling and mucoadhesive acetaminophen liquid suppository was developed to improve the patient compliance of conventional solid suppository. In this study, acetaminophen liquid suppository, Likipe $n_{R}$, [aminophen/Poloxamer 407/Poloxamer 188/so4ium alginate (5/15/19/0.6%)] with relation temperature at 30-36 "C and suitable gel strength and bioadhesive force, dissolution pattern similar to conventional solid type suppository, Suspe $n_{R}$, was developed. Furthermore, the bioequivalence of two acetaminophen products was evaluated in 16 normal male volunteers (age 22-27 yr, body weight 56-72 kg) following sidle rectal administration. Test product was Likipe $n_{R}$ suppository (Dong-Wha Pharm. Corp., Korea)and reference product was Suspe $n_{R}$204-212 suppository (Hanmi Pharm. Corp., Korea). Both products contain 125 mg of acetaminophen. Four Suppositories of the test and the reference product were administered to the volunteers, respectively, by randomized two period cross-over study (2$\times$2 Latin square method). The determination of acetaminophen was accomplished using HPLC. Average drug concentrations at each sampling time and pharmacokinetic parameters calculated were not significantly different between two products (p>0.05); the area under the curve to last sampling time (24 hr) (AU $Co_{-2}$4h/) (30.14$\pm$8.64 vs 27.98$\pm$ 6.53 $\mu$g .h/ml), maximum plasma concentration ( $C_{max}$) (3.29$\pm$0.87 vs 3.60$\pm$0.66 $\mu$g/ml) and time to maximum plasma concentration ( $T_{max}$) (2.91 $\pm$0.55 vs 2.69$\pm$0.60 h). The differences of mean AUCo $_{24h}$, C-a. and T-between the two products (7.18%, 9.58% and 7.53%, respectively) were less than 20%. The power (1-7) and treatment difference ($\Delta$) for AU $Co_{24h}$, $C_{max}$ and $T_{max}$ were more than 0.8 and less than 0.2, respectively at $\alpha$=0.1. The confidence limits for AU $Co_{24h}$, $C_{max}$ and $T_{max}$ (-0.81 ~13.55%, -1.56~ 17.60 and -3.81 ~18.87%, respectively) were less than $\pm$ 20% at $\alpha$=0.1. These results suggest that the bioavailability of Likipe $n_{R}$ suppository is not significantly different from that of Suspe $n_{R}$ suppsitory. Therefore, two products are bio-equivalent based on the current results.results.lts.sults.results.lts.
