Objective : This study was carried out to investigate the effects of Jisildochehwan extract on indomethacin-induced gastric mucosal lesions of mice. as compared with misoprostol. Methods : Experimental mice were classified into four groups. No gastro-inflammation elicited mice were the normal group(NOR). Gastro-inflammation elicited mice were the control group (CON). Misoprostol-administered mice after gastro-inflammation elicitation were the misoprostol-administered group (MA). Jisildochehwan-administered mice after gastro-inflammation elicitation were the Jisildochehwan-administered group(JA). In this study, we examined superoxide dismutase(SOD) ability, anti-inflammatory ability arrangement of mucous-secreted cells. distribution of mucosal neck cells, mucosal surface cells. neutral mucous-secreted cells. PAS reaction. COX-1, $TNF-{\alpha}$, $NF-{\kappa}B$ p65 and iNOS. Results : The SOD ability of the Jisildochehwan group increased dose-dependently. The hemorrhagic erosion and the damage of arrangement of mucous-secreted cells increased in the CON group. but decreased in the MA and JA groups. The COX-1 positive were decreased in the CON group, but increased in the MA and JA groups. The distribution of mucosal neck cells and mucosal surface cells. PAS positive reaction of surface mucous cells were decreased in CON group, but increased in MA and JA group. $TNF-{\alpha}$, $NF-{\kappa}B$ p65 and iNOS increased in the CON group, but decreased in the MA and JA groups. In all the results, the effects were better in the JA group than in the MA group. Conclusion : Jisildochehwan extract was more effective than Misoprostol. Jisildochehwan has excellent protective effects on indomethacin-induced gastric mucosal lesions.

The purpose of this study was to investigate the dietary effects of persimmon peel (PP) and PP ethanol extract (PPE) on egg production, egg quality, and liver lipids in the late stage of egg production in laying hens. One hundred and twenty 50-wk-old Hy-Line Brown layers (n = 120) were fed different diets. Four replicate groups of 6 hens each were randomly assigned to 5 dietary treatments. The 5 dietary treatments were as follows: i) CON, basal diet; ii) PP 0.15, CON+0.15% PP (0.035% tannin); iii) PP 0.5, CON +0.5% PP (0.117% tannin); iv) PPE 0.075, CON+0.075% PPE (0.03% tannin); and v) PPE 0.25, CON+0.25% PPE (0.11% tannin). The total tannin concentration of PPE was higher (p<0.05) than that of PP. Egg production in the PP 0.5 group was higher than in the other groups. Egg production and mass of hens in the PPE 0.25 group showed a greater decrease than that in the other groups (p<0.05). Eggshell color in the PP 0.15, PP 0.5, and PPE 0.075 groups was lighter than that of the control group (p<0.05). The Haugh unit for the groups that were fed PP and PPE were significantly higher than that in the other groups after 7 d of storage (p<0.05). Therefore, PP seems an effective feed additive for improving the production performance and egg quality in late stage laying hens.

In this study, we aimed to investigate the effect of GamiChungYi-tang(GCY-t) on caerulein-induced acute pancreatitis (AP). It is performed by detecting oxidative stress markers and observing histopathological examination. Thirty adult male rats(Sprague-Dawley) were divided into six groups as follows: normal (NOR,n=5), caerulein-induced (CON,n=5), caerulein+Cefotaxime Sodium(CT,n=5), caerulein+GCY-t (130 mg/kg, CHA,n=5), caerulein+GCY-t (260 mg/kg, CHB,n=5) and caerulein+GCY-t (520 mg/kg, CHC,n=5) groups. Pancreatic tissues of rats from all groups were removed for apoptosis and light, and electron microscopic examination. Blood of rats from all groups were collected for oxidative stress markers inspection and pathological examination. Pancreatic oxidative stress markers were evaluated by the measurements of leukocyte, serum amylase and platelet activating factor (PAF), Interleukin-6 (IL-6) levels were determined spectrophotometrically. CON group has a significant increase (p<0.05) in amylase compared with NOR, but CT and CHA, CHB, CHC groups reduced the levels of these enzyme. The levels of Platelet activating factor (PAF) were increased in CON compared with NOR, but decreased in CT and CHA, CHB, CHC groups compared with CON. Interleukin-6 (IL-6) levels were increased significantly in CON compared with NOR, but reduced in CT and CHA, CHB, CHC groups. In the observations of Optical microscopy and electron microscopy, The experimental groups showed the significant decreases in pancreatic tissue inflammation, edema, vacuolization, necrosis compared to the control group. After all, GCY-t is potentially capable of limiting pancreatic damage produced during AP by restoring the fine structure of acinar cells and tissue.

PURPOSE: The purpose of this study was to investigate and evaluate muscle activity and foot pressure during gait, and isokinetic strength and balance in persons with functional ankle instability (FAI). METHODS: Nine healthy subjects (CON, n=9) without FAI and 11 patients (FAI, n=11) with FAI participated in the study after having been screened with an ankle instability instrument and a balance error scoring system. In addition, FAI was classified as non-involved (FAI-N) or involved (FAI-I), and CON was classified as dominant or non-dominant. All subjects were evaluated for isokinetic strength (plantar flexion, dorsiflexion, inversion and eversion of $30^{\circ}/sec$ and $60^{\circ}/sec$), balance (static and dynamic), muscle activity (tibialis anterior, peroneus longus and gastrocnemius) and foot pressure (static and dynamic) during gait. RESULTS: Results showed that plantar flexion (p<.05), dorsiflexion (p<.05), inversion (p<.01) and eversion (p<.00) of $60^{\circ}/sec$ were significantly decreased in FAI-I compared to those in FAI-N and CON. C 90 of static balance with eyes open (p<.01) and closed (p<.00) were significantly increased in FAI compared to those in CON. Forward position of dynamic balance (p<.01) was significantly decreased in FAI compared to that in CON. Gastrocnemius and peroneus longus of dynamic muscle activity (p<.01), left and right weight distribution of static foot pressure (p<.00) and pressure distribution of dynamic foot pressure (p<.00) were significantly decreased in FAI-I compared to those in FAI-N. CONCLUSION: We demonstrated that ankle strength, balance, muscle activity and foot pressure were significantly correlated with FAI.

우주시스템 개발은 많은 이해당사자(stakeholder)의 다양한 기대조건(expectations)을 효율적으로 반영하여 개발 요구조건을 확정하는 것은 매우 중요하다. 나로호 개발에서 이해당 사자의 기대조건의 반영여부를 분석하고 현재 진행 중인 한국형발사체 사업의 기획도 분석하였다. 나로호 개발은 조기 개발을 원하는 정부의 의지가 일방적으로 반영되었으며 연구기관, 대학교, 참여업체 등이 제시할 수 있는 기술적 제한요소, 활용가능성, 발전계획 등의 주제가 제외되었다. 또한 개발이 완료된 후에 발사체를 어떻게 운영할 것인가를 정의하는 운영개념(ConOps)도 확정되지 않았다. 한국형 우주발사체(KSLV-II )개발 기획도 정부와 항공우주연구원을 비롯한 이해당사자 기대조건을 함께 반영하고 기술적 제한조건과 비-기술적 요소들을 고려하는 과정이 부족했던 것으로 보인다. 한편 KSLV-II 사업의 최근 정부 개발 방안은 개발 목표의 불확실성과 이해당사자들의 의견 불일치 등이 예상되어 시급한 보완이 필요하며. 개발 초기에 설계 요건을 재검토하고 운영개념(ConOps)을 정립할 수 있는 방안이 요구된다.

Objectives : The aim of this study was to investigate the effects of licorice supplementation on muscle injury, plasma cortisol, testosterone and insulin sensitivity after high intensity resistance exercise. Methods : The fourteen health college male students were voluntarily participated in this study and were randomly divided into 2 groups: Control group (CON, n=7), Licorice group (LR, n=7). LR group ingested 2 g/time of licorice extract (mixed with 100 ml of water) two times/day for 10 days while the CON group ingested 100 ml of water. All subjects performed a high intensity resistance exercise (half-squat, 8 RM at 80% one-repetition maximum, 5 sets, 1min rest). Blood samples were collect before (-7) and after (0) licorice supplementation, and then 1 day, 2 day and 3 day post exercise. After 10 day treatment, plasma creatine kinase, cortisol, testosterone, glucose, insulin were measured. To determine the insulin sensitivity, HOMA-IR was calculated. Results : Plasma creatine kinase activities were significantly elevated after exercise, but there was not different between two groups. The plasma cortisol and testosterone levels were not significantly different between two groups. Plasma glucose levels were increased at 1 day and 2 day after exercise in the LR comparing with CON group (P<0.05) but plasma insulin levels were significantly lower in comparison with CON. HOMA-IR were significantly lower in the LR than CON group at 0 day to 3 day (P<0.05). Conclusions : The results of the current study suggest that licorice supplementation for 10 days might not attenuate the high-intensity exercise-induce muscle injury but may enhance the whole-body insulin sensitivity.

Ketosis is associated with high milk yield during lactating or insufficient feed intake in lactating dairy cows. However, few studies have been conducted on the metabolomics of ketosis in Korean lactating dairy cows. The present study aimed to investigate the serum and urine metabolites profiling of lactating dairy cows through proton nuclear magnetic resonance (¹H-NMR) spectroscopy and comparing those between healthy (CON) and subclinical ketosis (SCK) groups. Six lactating dairy cows were categorized into CON and SCK groups. All experimental Holstein cows were fed total mixed ration. Serum and urine samples were collected from the jugular vein of the neck and by hand sweeping the perineum, respectively. The metabolites in the serum and urine were determined using ¹H-NMR spectroscopy. Identification and quantification of metabolites was performed by Chenomx NMR Suite 8.4 software. Metabolites statistical analysis was performed by Metaboanalyst version 5.0 program. In the serum, the acetoacetate level was significantly (p < 0.05) higher in the SCK group than in the CON group, and whereas acetate, galactose and pyruvate levels tended to be higher. CON group had significantly (p < 0.05) higher levels of 5-aminolevulinate and betaine. Indole-3-acetate, theophylline, p-cresol, 3-hydroxymandelate, gentisate, N-acetylglucosamine, N-nitrosodimethylamine, xanthine and pyridoxine levels were significantly (p < 0.05) higher in the urine of the SCK group than that in the CON group, which had higher levels of homogentisate, ribose, gluconate, ethylene glycol, maltose, 3-methyl-2-oxovalerate and glycocholate. Some significantly (p < 0.05) different metabolites in the serum and urine were associated with ketosis diseases, inflammation, energy balance and body weight. This study will be contributed useful a future ketosis metabolomics studies in Korea.

Objective: Three experiments were conducted to evaluate the effects of Saccharomyces yeast postbiotics (SYP) in feeds for sows on the growth of offspring (Exp. 1), for nursery pigs on their growth (Exp. 2), and for nursery and finishing pigs on their growth (Exp. 3). Methods: Exp. 1 had 80 sows at breeding assigned to 4 groups with SYP at 0, 0.050, 0.175, and 0.500 g/kg. Offspring were fed a common diet for 126 d. Exp. 2 had 144 barrows at 8 kg body weight (BW) allotted to CON (no SYP); YPC (SYP at 0.175 g/kg; d 0 to 42); and YPD (SYP at 1.25, 0.75, and 0 g/kg; d 0 to 7, d 8 to 21, and d 22 to 42, respectively) with 8 pens/treatment (6 pigs/pen). Exp. 3 had 96 barrows at 8 kg BW allotted to CON (no SYP); YPN (SYP at 0.175 g/kg; d 0 to 42); YPF (SYP at 0.100 g/kg; d 43 to 119); and YPA (SYP at 0.175 and 0.100 g/kg; d 0 to 42 and d 43 to 119, respectively) with 8 pens/treatment (3 pigs/pen). Results: In Exp. 1, increasing SYP increased (p<0.05, quadratic) the sow body score (maximum at 0.30% SYP), reduced (p<0.05, quadratic) the days-wean-to-estrus (minimum at 0.27% SYP), and increased (p<0.05) offspring BW at weaning and their average daily gain (ADG) and feed efficiency (G:F) at d 126. In Exp. 2, ADG, average daily feed intake (ADFI), and G:F of YPC were the greatest (p<0.05). The ADG and ADFI of YPD were greater (p<0.05) than CON. Fecal score of YPC and YPD was smaller (p<0.05) than CON. In Exp. 3, YPA had the greatest (p<0.05) ADG and YPN and YPF had greater (p<0.05) ADG than CON. Conclusion: SYP enhanced sow performance, offspring growth, growth of nursery and growing pigs with the greater efficacy at 0.27 to 0.32 g/kg feed.

Bakery waste (BW) is much cheaper than barley (20 to 40% the price of barley). Bakery waste and barley grain have similar chemical composition; they contain 99 and 97% organic matter (OM), 1.1 and 1.8% fat, 18 and 15% neutral detergent fibre (NDF) and 14.0 and 14.5% crude protein (CP), respectively (DM basis). The objectives of this study were to determine the effect of substituting BW for barley grain in high concentrate fattening diets for lambs on nutrient intake, growth and carcass characteristics. Forty Awassi lambs (21.75${\pm}$1 kg) weaned at the age of 65 days were assigned randomly to four experimental fattening diets differing in BW ratio in a completely randomized design. The control diet (CON) contained 20, 60, 11, 7, and 2% (DM basis) wheat straw, barley grain, soybean meal, corn grain, and minerals and vitamin mix, respectively. Bakery waste substituted barley grain by 10, 20 and 30% of the diet DM in the LBW, MBW and HBW diets, respectively. The experiment lasted for 56 days. Dry matter intake (DMI) decreased (p<0.05) in LBW diet compared to the CON diet by approximately 10%. No further reduction in DMI was observed with the higher substitution levels. Metabolizable energy intake for the CON diet (3.6 Mcal/d) was also reduced (p<0.05) compared with LBW, MBW and HBW diets (3.4, 3.4 and 3.3 Mcal/d, respectively). Final body weight for lambs fed the CON diet (34.8 kg) was higher (p<0.05) compared with lambs fed the LBW, MBW and HBW diets (30.6, 32.0 and 31.1 kg, respectively). Growth rate for lambs fed the CON diet (232 g/d) was also higher (p<0.05) compared to lambs fed the LBW, MBW and HBW diets (170, 189, and 167 g/d, respectively). Feed to gain ratio was higher (p<0.05) for lambs fed the LBW, MBW and HBW diets (7.2, 6.6 and 7.3, respectively) compared with lambs that consumed the CON diet (5.7). Body weight gain cost was reduced by approximately 8% by the MBW and HBW diets as compared with the CON diet. Dressing percentage, full gut weight, empty gut weight and liver weights were all unaffected by the BW addition to the diets and averaged 48.9%, 6.8 kg, 2.8 kg and 0.444 kg, respectively. However, fat tail weight was increased (p<0.05) with the higher levels of the BW inclusion. In conclusion, substituting BW for barley grain reduced DMI and growth performance. However, when BW substituted barley grain at the 20 and 30% of the diet DM, body weight gain cost was reduced by approximately 8%.
