  • Objective: This study was conducted to evaluate the effect of offering (OSF) or not (NSF) supplemental feed at milking on temperament (TS), udder hygiene (UHS) and body condition (BCS) scores, and milk yield per milking (MYM), milk quality traits, and profitability of primiparous Anatolian buffalo cows at 90 days of lactation confined in closed-tied (CB) or semi-open free-stall (OB) barns. Methods: In Experiment I, 108 cows were selected to encompass four treatments (OBOSF, OB-NSF, CB-OSF, and CB-NSF) of 27 cows, considering barn type (OB and CB) and supplementary feed (OSF and NSF) at milking. In Experiment II, 60 OB cows were selected to encompass one of five groups of 12 cows each: i) no supplemental feed (CON), ii) commercial concentrate (CC), iii) CC + corn silage (CCS), iv) CCS + alfalfa hay (CSA), or v) CC + ryegrass silage (CRS) at milking. Results: The TS and UHS of the OB and OSF cows were lower (better) than those of the CB and NSF cows, respectively. The OSF increased milk protein, lactose, and solids-not-fat but decreased milk freezing point and electrical conductivity compared with the NSF. The MYM and milk fat of the OB-OSF cows were higher than those of the OB-NSF and CBNSF cows. The TS and UHS of the cows negatively correlated with MYM and some milk chemicals (fat, protein, and solids-not-fat), but BCS correlated positively. The TS and milk electrical conductivity of the CCS, CSA, and CRS cows were lower than those of the CON and CC cows, but BCS, MYM, and milk fat were higher. Partial budget analysis identified a higher net profit for supplemental feed-offered groups (OB-OSF, CCS, CSA, and CRS). Conclusion: Offering roughage with concentrates at milking for indoor primiparous buffalo cows is more conducive to well-being, milk yield, milk quality, and economy.

  • Silk fibroin scaffolds were examined as a biomaterial option for tissue-engineered cartilage-like tissue. In tissue engineering for cartilage repair using a scaffold, initial chondrocyte-material interactions are important for the following cell behaviors. In this study, the surface of nanofibrous silk fibroin (NSF) meshes was modified by a microwave-induced argon plasma treatment in order to improve the cytocompatibility of the meshes used as cartilaginous grafts. In addition, the effects of a plasma treatment on the cellular behavior of chondrocytes on NSF were examined. The plasma treatment resulted in an increase in the hydrophilicity of NSF meshes suggesting that the cytocompatibility of the mesh might be improved. Furthermore, the human articular chondrocytes showed higher viability on the surface-modified NSF meshes. These results suggest that the surface modification of NSF meshes by plasma can enhance the cellular behavior of chondrocytes and may be used in tissue engineering.

  • This study was conducted to compare the sensory and enzymatic properties of Israeli carp Cyprinus carpio muscle (ICM) according to size [normal large (NLF) and small fish (NSF)], part [ventral (VM) and dorsal muscles (DM)], and commercial value [NLF, recessive (RF), or deformed fish (DF)]. There was not difference in salty of all samples. The sourness was stronger in NLF and DM than in NSF, RF, and DF, and VM, respectively. The umami of ICM showed no size-associated differences; however, those of DM, and DF and RF, were superior to those of the VM and NLF, respectively. The sweetness was also stronger in NLF than in NSF and RF, and in DM than VM. The sweetness of DF didn't differ compared to those of NLF and RF. The intensity of fish odor was weaker in NSF or DF than that in NLF, and was higher in DM than in VM. The color of ICM was bright in NSF and DF compared to NLF. Enzyme activity was very low in the muscles and high in viscera. Therefore, ICM could be used as a material for seafood products, regardless of size, part, and commercial value; however, the issue of lipid oxidation must be considered.

  • Background: Korean Red Ginseng (KRG) is an ethnopharmacological plant that is traditionally used to improve the body's immune functions and ameliorate the symptoms of various diseases. However, the antitumorigenic effects of KRG and its underlying molecular and cellular mechanisms are not fully understood in terms of its individual components. In this study, in vitro and in vivo antitumorigenic activities of KRG were explored in water extract (WE), saponin fraction (SF), and nonsaponin fraction (NSF). Methods: In vitro antitumorigenic activities of WE, SF, and NSF of KRG were investigated in the C6 glioma cell line using cytotoxicity, migration, and proliferation assays. The underlying molecular mechanisms of KRG fractions were determined by examining the signaling cascades of apoptotic cell death by semiquantitative reverse transcriptase polymerase chain reaction and Western blot analysis. The in vivo antitumorigenic activities of WE, SF, and NSF were investigated in a xenograft mouse model. Results: SF induced apoptotic death of C6 glioma cells and suppressed migration and proliferation of C6 glioma cells, whereas WE and NSF neither induced apoptosis nor suppressed migration of C6 glioma cells. SF downregulated the expression of the anti-apoptotic gene B-cell lymphoma-2 (Bcl-2) and upregulated the expression of the pro-apoptotic gene Bcl-2-associated X protein (BAX) in C6 glioma cells but had no effect on the expression of the p53 tumor-suppressor gene. Moreover, SF treatment resulted in activation of caspase-3 as evidenced by increased levels of cleaved caspase-3. Finally, WE, SF, and NSF exhibited in vivo antitumorigenic activities in the xenograft mouse model by suppressing the growth of grafted CT-26 carcinoma cells without decreasing the animal body weight. Conclusion: These results suggest that WE, SF, and NSF of KRG are able to suppress tumor growth via different molecular and cellular mechanisms, including induction of apoptosis and activation of immune cells.

  • 본 연구는 전국체육대회에 참가하는 재외동포의 세대 간 참가동기, 참가경험 및 정체성교섭에 대한 차이를 실증적으로 분석하는데 그 목적이 있다. 이와 같은 연구의 목적을 달성하기 위해서 본 연구는 2019년 제 100회 전국체육대회에 참가한 재외동포를 모집단으로 설정하고, 실제 360명의 자료를 수집해 분석하였다. 이러한 연구의 목적과 연구방법을 토대로 얻어진 결과는 다음과 같다. 첫째, 전국체육대회에 참가하는 재외동포의 세대 간 참가동기 중 이주 1세대의 경우 가족방문과 정체성유지가 1.5세대나 2세대보다 높다. 하지만, 자아실현을 추구하기 위한 참가동기의 경우 이주 1.5세대나 2세대가 1세대보다 높다. 둘째, 전국체육대회에 참가하는 재외동포의 세대 간 참가경험은 두 집단 모두 긍정경험에서는 통계적으로 유의한 차이가 없었으나, 이주 1.5세대나 2세대가 1세대보다 전국체육대회 동안 부정적인 경험이 높다. 셋째, 전국체육대회에 참가하는 재외동포의 세대 간 정체성교섭은 이주 1세대의 경우 모국정체성이 1.5세대와 2세대는 거주국 정체성이 높다.

  • Spin finish(NSFs) for synthetic fiber were prepared. NSF-3 was proved to be the best spin finish by testing the properties and emulsion stability, etc. of NSFs. NSF-3 prepared by blending of spindle oil 70g, paraffin wax 10g, glyceryl mono-oleate 5g, POE(10) nonylphenyl ether 4g, POE(20) sorbitan tri-oleate 4g, Na-dioctyl sulfosuccinate 4g, antistatic agent 2g and water 1g was excellent in its characteristics. Optimum physical conditions of nylon filament treated with NSF-3 according to the number of revolution of oil roller were obtained at conditions of 5.5rpm in the number of revolution of oil roller, 1.21% of oil pick up, and denier 69.2D.
