이 논문에서는 대규모 시위의 성격과 미국에서의 특정한 사례를 들어 이러한 사건들에 대한 경찰 대응에 대하여 검증해보고자 한다 보다 구체적으로 이 논문에서는 도시 경찰력의 규모와 시위 사이의 관계, 시위의 변화하는 성격과 공공의 질서 유지, (public order maintenance)의 관계, 그리고 미국의 두 관할구역에서 이른바 `시위 대응 경찰활동(protest policing)`이라 여겨지는 것의 본질과 법집행 기관이 조직문화라는 맥락 속에서 대규모 집회와 시위를 다루는데 적용한 특수한 접근법들 사이의 관계에 대해 검증하고자 한다. In this paper, we examine the nature of mass demonstrations and police responses to these events with specific examples from the United States. More specifically, we examine the relationship between the police size of cities and protests, changing nature of protests and public order maintenance, and the nature of what is commonly referred to as `protest policing` in two jurisdictions in the U.S. and the specific approaches they have adopted to handle these mass protests and demonstrations within the context of the organizational culture of the law enforcement departments.

Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent liver diseases associated with an altered lifestyle, besides genetic factors. The control and management of NAFLD mostly depend on lifestyle modifications, due to the lack of a specific therapeutic approach. In this context, we assessed the effect of carrot juice on the development of high fructose-induced hepatic steatosis. For this purpose, male weanling Wistar rats were divided into 4 groups, fed either a control (Con) or high fructose (HFr) diet of AIN93G composition, with or without carrot juice (CJ) for 8 weeks. At the end of the experimental period, plasma biochemical markers, such as triglycerides, alanine aminotransferase, and ${\beta}$-hydroxy butyrate levels were comparable among the 4 groups. Although, the liver injury marker, aspartate aminotransferase, levels in plasma showed a reduction, hepatic triglycerides levels were not significantly reduced by carrot juice ingestion in the HFr diet-fed rats (HFr-CJ). On the other hand, the key triglyceride synthesis pathway enzyme, hepatic stearoyl-CoA desaturase 1 (SCD1), expression at mRNA level was augmented by carrot juice ingestion, while their protein levels showed a significant reduction, which corroborated with decreased monounsaturated fatty acids (MUFA), particularly palmitoleic (C16:1) and oleic (C18:1) acids. Notably, it also improved the long chain n-3 polyunsaturated fatty acid, docosahexaenoic acid (DHA; C22:6) content of the liver in HFr-CJ. In conclusion, carrot juice ingestion decreased the SCD1-mediated production of MUFA and improved DHA levels in liver, under high fructose diet-fed conditions. However, these changes did not significantly lower the hepatic triglyceride levels.

Seven unrecorded species in the phylum Ascomycota, Emericellopsis pallida (KNU16-167), Scedosporium aurantiacum (KNU16-190), Duddingtonia flagrans (KNU16-279), Bionectria rossmaniae (KNU16-309), Exophiala xenobiotica (KNU16-79), Pseudocercosporella fraxini (KNU16-102), and Stachybotrys sansevieriae (KNU16-141), were isolated in 2016 from field soils collected from various locations in Korea. All of the species were identified and described based on morphological characteristics and rDNA internal transcribed spacer sequence data. Morphological features of these fungi were examined on potato dextrose agar, oatmeal agar, malt extract agar, Czapek yeast extract agar, and yeast extract sucrose agar. Full descriptions and illustrations of their morphological characteristics are provided.

This study evaluated the microbial conversion of coconut oil waste, a major agro-residue in tropical countries, into single cell oil (SCO) feedstock for biodiesel production. Copra cake was used as a low-cost renewable substrate without any prior chemical or enzymatic pretreatment for submerged growth of an oleaginous tropical mangrove fungus, Aspergillus terreus IBB M1. The SCO extracted from fermented biomass was converted into fatty acid methyl esters (FAMEs) by transesterification and evaluated on the basis of fatty acid profiles and key fuel properties for biodiesel. The fungus produced a biomass (8.2 g/l) yielding 257 mg/g copra cake SCO with ~98% FAMEs. The FAMEs were mainly composed of saturated methyl esters (61.2%) of medium-chain fatty acids (C12-C18) with methyl oleate (C18:1; 16.57%) and methyl linoleate (C18:2; 19.97%) making up the unsaturated content. A higher content of both saturated FAMEs and methyl oleate along with the absence of polyunsaturated FAMEs with ≥4 double bonds is expected to impart good fuel quality. This was evident from the predicted and experimentally determined key fuel properties of FAMEs (density, kinematic viscosity, iodine value, acid number, cetane number), which were in accordance with the international (ASTM D6751, EN 14214) and national (IS 15607) biodiesel standards, suggesting their suitability as a biodiesel fuel. The low cost, renewable nature, and easy availability of copra cake, its conversion into SCO without any thermochemical pretreatment, and pelleted fungal growth facilitating easier downstream processing by simple filtration make this process cost effective and environmentally favorable.
Private Police in Emerging Markets: South Korea
Mahesh K,Nalla,Eui-Gab Hwang 아시아경찰학회 2003 아시아경찰학회 국제학술회의 Vol.2003 No.-
The Republic of Korea (South Korea) has made significant progress in the market sector in the past four decades. Relative to its neighbors in Asia, South Korea has increased its market base both in terms of production and consumption. Along with economic growth, South Korea has also experienced an increase in the employment of private security personnel. Despite large increases in the growth of the private policing industry in the last four decades in the emerging markets, we know very little about how the public perceives agents of private policing. In this paper we examine South Korean youth perceptions of private security officers. Responses were received from 172 college students. The findings suggest that respondents generally held positive attitudes toward security work and security officers.
Alternative Methods for Testing Botulinum Toxin: Current Status and Future Perspectives
( Mahesh Raj Nepal ),( Tae Cheon Jeong ) 한국응용약물학회 2020 Biomolecules & Therapeutics(구 응용약물학회지) Vol.28 No.4
Botulinum toxins are neurotoxic modular proteins composed of a heavy chain and a light chain connected by a disulfide bond and are produced by Clostridium botulinum. Although lethally toxic, botulinum toxin in low doses is clinically effective in numerous medical conditions, including muscle spasticity, strabismus, hyperactive urinary bladder, excessive sweating, and migraine. Globally, several companies are now producing products containing botulinum toxin for medical and cosmetic purposes, including the reduction of facial wrinkles. To test the efficacy and toxicity of botulinum toxin, animal tests have been solely and widely used, resulting in the inevitable sacrifice of hundreds of animals. Hence, alternative methods are urgently required to replace animals in botulinum toxin testing. Here, the various alternative methods developed to test the toxicity and efficacy of botulinum toxins have been briefly reviewed and future perspectives have been detailed.

A unrecorded hyphomycete species of Phialocephala was isolated for the first time during the investigation of fungal community in the soil samples collected from different regions of Korea. The fungal isolate was identified as Phialocephala lagerbergii, based on the morphological characteristics and phylogenetic analysis of the ribosomal DNA sequence. In addition, cultural and micro-morphological features were described in detail.

Background/Aims: To evaluate patients with portal hypertension (PH) of varied etiologies for portal hypertensive enteropathy (PHE)using the PillCam SB3 capsule endoscopy (CE) system. Methods: Consecutive patients with PH presenting with unexplained anemia and/or occult gastrointestinal bleeding were evaluatedusing the PillCam SB3 CE system. Abnormal findings were categorized as vascular or non-vascular. The patients with ongoing bleedingcaused by PHE were treated. The correlation of the CE scores of PHE with the clinical, laboratory, and endoscopic features wasdetermined. Results: Of the 43 patients included in the study, 41 (95.3%) showed PHE findings. These included varices (67.4%), red spots (60.5%),erythema (44.2%), villous edema (46.5%), telangiectasia (16.3%), and polyps (16.3%). The CE scores varied from 0 to 8 (mean±standarddeviation, 4.09±1.8). Five patients (11.6%) showed evidence of ongoing or recent bleeding due to PHE. Three of these five patientsunderwent endotherapy, and one patient underwent radiological coil placement. Conclusions: The PillCam SB3 CE system revealed a high prevalence of PHE in the patients with PH. Using this system, evidence ofbleeding due to PHE was found in a small but definite proportion of the patients.
