The purpose of this study was to demonstrate the quality characteristics of Brassica juncea cultivated in Jeongseon (BJJ), South Korea. We analyzed the nutritional components and antioxidant activity of BJJ. As a result of the free sugar analysis, the contents of glucose and fructose in BJJ were $0.29{\pm}0.02g/100g$ and $0.10{\pm}0.00g/100g$, respectively. The major fatty acids were palmitic acid, octadecenoic acid and stearic acid. The palmitic acid was the highest at 31.22% of all fatty acids. The major minerals were identified as Ca, P, K, Mg and Na. The contents of vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, vitamin C and vitamin E in BJJ were $0.02{\pm}0.00mg/100g$, $0.087{\pm}0.01mg/100g$, $0.02{\pm}0.00mg/100g$, $0.56{\pm}0.06mg/100g$ and $0.20{\pm}0.03mg\;{\alpha}-TE/100g$, respectively. As a result of the free amino acid analysis, total amino acid contents in BJJ were $2,801.21{\pm}115.38mg/100g$. L-proline content was the highest ($744.30{\pm}119.06mg/100g$) in BJJ. BJJ extract inhibits reactive oxygen species production in 3T3-L1 adipocytes. Also, BJJ extract exhibits a protective effect on oxidative stress in $H_2O_2$-induced human dermal fibroblast.

황산화 미생물인 Genus Thiobacillus 중 몇 종류의 탈질균은 여러 종류의 황 화합물($S^{2-}$, So, $S_2O{_3}^{2-}$, $S_4O{_6}^{2-}$, $SO{_3}^{2-}$)을 황산염이온으로 산화시키면서 동시에 질산성질소를 질소 가스 형태로 전환시킨다. 이는 독립영양 미생물이므로 외부 탄소원이 필요치 않으며, C/N비가 낮은 폐수에 에탄올 대신 값이 싼 황 입자의 투입으로 경제적이며 효과적인 탈질화를 유도할 수 있다. 후탈질시 인위적인 유기물의 투입대신 값 싼 황입자를 사용하여 질소를 제거하며, 처리효율이 안정적이고, 운전이 쉬워, 최근 이 공정은 세계적으로 많이 연구되고 있다. 그러나 탈질시 알칼리도가 파괴되어 특히 알칼리도가 낮은 폐수의 경우 고농도 탈질시 pH가 떨어져 탈질이 더 이상 진행되지 않으며, 고농도의 질산성질소를 처리할 경우 부산물로서 고농도의 황산염이온이 생성된다는 부수적인 단점을 안고 있다. 본 연구에서는 MCR로부터 독립영양 미생물을 분리 characterization 및 미생물 동정을 하였다. MCR내에는 주로 Paracoccus denitrificans and Paracoccus versutus (formerly Thiobacillus versutus)가 주종을 이루었으며 이들 미생물들은 유기물도 에너지원으로 이용할 수 있는 facultative autotrophic denitrifier이었다. 이들 미생물을 탈질에 이용할 시 유기물이 있는 조건에서도 성장하기 때문에 유입 폐수 내 유기물 농도에 영향을 받지 않고 또는 인위적으로 소량의 유기물을 넣어 독립영양탈질과 종속영양탈질을 동시에 일어날 수 있도록 함으로서 독립영양탈질의 단점인 높은 황산염이온 생성 및 알칼리도 파괴를 막을 수 있을 것으로 사료된다.

A new Korean standard for the determination of Cr(VI) in soils has been officially published as ES 07408.1 in 2009. This analytical method is based on the hot alkaline digestion and colorimetric detection prescribed by U.S. EPA method 3060A and 7196A. The hot alkaline digestion accomplished using 0.28 M $Na_2CO_3$ and 0.5 M NaOH solution (pH 13.4) at $90{\sim}95^{\circ}C$ determines total Cr(VI) in soils extracting all forms of Cr(VI), including water-soluble, adsorbed, precipitated, and mineral-bound chromates. This aggressive alkaline digestion, however, proved to be problematic for certain soils which contain large amounts of soluble humic substances or active manganese oxides. Cr(III) could be oxidized to Cr(VI) by manganese oxides during the strong alkaline extraction, resulting in overestimation (positive error) of Cr(VI). In contrast, Cr(VI) reduction by dissolved humic matter or Fe(II) could occur during the neutralization and acidic colorimetric detection procedure, resulting in underestimation (negative error) of Cr(VI). Futhermore, dissolved humic matter hampered the colorimetric detection of Cr(VI) using UV/Vis spectrophotometer due to the strong coloration of the filtrate, resulting in overestimation (positive error) of Cr(VI). Without understanding the mechanisms of Cr(VI) and Cr(III) transformation during the analysis it could be difficult to operate the experiment in laboratory and to evaluate the Cr(VI) results. For this reason, in this paper we described the theoretical principles and limitations of Cr(VI) analysis and provided useful guidelines for laboratory work and Cr(VI) data analysis.

Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) lower extremity patterns combined with elastic bands applied to stroke patients diagnosed with hemiplegia through self-training using the non-paralyzed side approach and the paralyzed side approach, and to investigate the differences in the effects. Methods: Nine chronic stroke patients who were being treated not more than twice a week at H, K, R, and C hospitals located in Gangwon-do, performed self-training for 16 minutes, two times per day for four weeks between August and October 2015. The subjects' balance ability was measured using the Tetrax stability index, the weight distribution index, the Berg Balance Scale (BBS), and the Timed Up and Go (TUG) test before the experiment and four weeks later. Among the statistical methods, paired t-tests were conducted for intra-group comparison of the measurements taken before and after the experiment, and independent t-tests were conducted for inter-group comparison of the ex post facto values. The statistical significance level was set to 0.05. Results: When the lower extremity patterns were applied to the non-paralyzed side group and the paralyzed side group, significant intra-group differences were observed for the Tetrax stability index, the weight distribution index, the Berg Balance Scale (BBS), and Timed Up and Go (TUG) tests (p<0.05); however, the inter-group comparisons showed no significant differences. Conclusion: The non-paralyzed side approach was found to be easy for patients to participate in and it also affected the patients' paralyzed side. Although the paralyzed side approach produced good exercise effects in a short period of time, it could result in adverse effects, such as a decrease in motivation and self-confidence. Therefore, these approaches are considered to be more effective when they are selectively applied depending on the purpose of the intervention and the degree of a patients' participation.

This study is to stabilize insoluble and unstable active ingredient which is Idebenone (INCI name: hydroxydecyl ubiquinone) in a multi-lamellar vesicle (MLV) and to stabilize it in the skin care cosmetics. Idebenone is good effective raw material in the treatment of Alzheimer's disease in the medical field and a powerful antioxidant in dermatology. It is well known as a substance that inhibits the formation of melanin and cleans the skin pigment. However, it did not dissolve in any solvent and it was difficult to apply in cosmetic applications. Niosome vesicle was able to develop a nano-particle by making a multi-layer of idebenone encapsulated with a nonionic surfactant, hydrogenated lecithin and glycine soja (soybean) sterols and passing it through a high pressure microfluidizer. Idebenone niosome vesicle (INV) has been developed to have the ability to dissolve transparently in water and to promote transdermal penetration. The appearance of the INV was a yellowish liquid having specific odor, and the particle size distribution of INV was about 10~80 nm. The pH was 5~8 (mean=6.8). This capsulation with idebenone was stored in a $45^{\circ}C$ incubator for 3 months and its stability was observed and quantitatively measured by HPLC. As a result, the stability of the sample encapsulated in the niosome vesicle (97.5%) was about 66.3% higher than that of the non-capsule sample of 32.5%. Idebenone 1% INV was used for the efficacy test and clinical trial evaluation as follows. The anti-oxidative activity of INV was 38.2%, which was superior to that of 12.8% tocopherol (control). The melanin-reducing effect of B16 melanoma cells was better than INV (17.4%) and Albutin (control) (9.6%). Pro-collagen synthesis rate was 128.2% for INV and 89.3% for tocopherol (control). The skin moisturizing effect was 15.5% better than the placebo sample. The elasticity effect was 9.7% better than the placebo sample. As an application field, INV containing 1% of idebenone is expected to be able to develop various functional cosmetic formulations such as skin toner, ampoule essence, cream, eye cream and sunblock cream. In addition, it is expected that this encapsulated material will be widely applicable to emulsifying agents for skin use in the pharmaceutical industry as well as the cosmetics industry.

We present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a shortduration anomaly (~0.4 days) near the peak of the light curve, which is caused by the resonant caustic. The event has a severe degeneracy with ∆𝜒² = 0.9 between the close and the wide binary lens models both with planet-host mass ratio q ≃ 0.007. We measure the angular Einstein radius but not the microlens parallax, and thus we perform a Bayesian analysis to estimate the physical parameters of the lens. We find that the OGLE-2019-BLG-0362L system is a super-Jovian-mass planet $M_p=3.26^{+0.83}_{-0.58}M_J $ orbiting an M dwarf $M_h=0.42^{+0.34}_{-0.23}M_{\odot}$ at a distance $D_L=5.83^{+1.04}_{-1.55}kpc$. The projected star-planet separation is ${\alpha}_{\bot}= 2.18^{+0.58}_{-0.72}AU$, which indicates that the planet lies beyond the snow line of the host star.

주요 계란 난백 단백질과 그 가수분해물은 일부 금속 킬레이트 특성을 갖는 기능성 식품 성분으로 알려져 있다. 식이 oxalate를 제거하기 위해 계란 난백 단백질과 그 가수분해물을 이용할 경우 신장 결석을 예방하는데 도움이 될 것이다. 본 연구의 목적은 계란 난백 단백질인 ovalbumin, ovomucin, ovotransferrin과 이 단백질들의 효소처리를 통해 얻은 가수분해물의 biogenic oxalate chelating 활성을 측정하는 것이었다. 채소 중에서 시금치를 과일 중에서 스타푸르트(starfruit)를 선택하여 HCl처리를 거쳐 옥살레이트 추출물(oxalates extract)을 제조하였다. 계란의 난백 단백질 중, ovalbumin, ovomucin, ovotransferrin를 선택하여 이들의 가수분해물과 함께 옥살레이트 추출물과 별도로 혼합하여 3℃에서 24시간 반응을 위한 배양을 시켰다. 원심분리 후 상등액을 HPLC로 분석하여 단백질과 가수분해물의 biogenic oxalate chelating 활성을 비교 분석하였다. 사용된 모든 계란 난백 단백질과 그 가수분해물은 시금치의 oxalates에 대한 biogenic oxalate chelating 활성을 보였다. 그러나열대과일인 starfruit의 oxalates에 대한 킬레이트 활성에서는ovalbumin, hydrolyzed ovalbumin, ovomucin만이 활성을 보였다. 전반적으로, hydrolyzed ovalbumin은 시금치와 스타프루트 모두에서 oxalates chelating 효과가 가장 좋았다. 따라서 계란의 난백 단백질과 그 가수분해물의 옥살산 킬레이트 활성이 있었으며, 식이 옥살산에 대한 영양 개선을 위한 소재로 개발 가능성이 있다. 그러나, 다른 과일과 야채에 대한 옥살레이트 킬레이트 활성과 특정 생체 내 조건에서의 계란 단백질의 옥살레이트 킬레이팅 효과를 검증하기 위한 추가 연구가 필요하다.
