The purport of this essay is to examine the possible compatibility of liberalism and perfectionism. Liberalism is typically considered as anti-perfectionism. So communitarian critique of liberalism focused on the effects of its anti-perfectionism. But liberalism could be interpreted as compatible with perfectionism. Joseph Raz attempts to develop and defend "perfectionist" liberalism. He rejects anti-perfectionist "neutrality" and claims that the goal of political action is to encourage pursuit of what is truly good and discourage pursuit of what is morally unworthy. Despite this strong perfectionist claim, Raz's political philosophy gives pride of place to individual liberty, or autonomy, which he considers to be intrinsically valuable. One exercises autonomy in choosing among a plurality of human goods. Nonetheless, Raz forthrightly denies the value of autonomy used to choose what is morally bad and says that society has no reason to protect worthless, much less morally evil, options. Raz is more conventionally liberal, however, in espousing a version of J. S. Mill's "harm principle", arguing that a due regard for autonomy rules out government use of coercive means to discourage "victimless" immoralities. However, there are some serious questions about whether Raz's strong perfectionism can support his principled rejection of "morals legislation". I think that if his strong perfectionism could be a little "weakened" and his autonomy could be interpreted as having only formal value rather than having intrinsic value, then his perfectionism could be compatible with liberalism.

The nutritional compositions and antioxidative activities of Korean commercial blueberry and raspberry were investigated. The proximate compositions were 10.47% and 22.67% in moisture, 2.66% and 2.64% in crude protein, 2.04% and 1.67% in crude fat, 81.36% and 70.19% in nitrogen free extracts, 1.48% and 0.85% in crude fiber, and 1.99% and 1.98% in ash of blueberry and raspberry, respectively. Total phenolics content were higher in blueberry (9.028 mg/g) than in raspberry (5.340 mg/g). Major elements of blueberry and raspberry were Ca (451.34 and 97.48 mg/100 g), K (355.40 and 215.20 mg/100 g), P (321.10 and 294.04 mg/100 g), and Na (137.58 and 137.67 mg/100 g). The total amino acid contents of blueberry and raspberry were 2,011.44 mg /100 g and 2,098.82 mg/100 g, respectively. Amino acid were mainly composed of glutamic acid, aspartic acid and leucine. The DPPH and ABTS radical scavenging activities of the 80% methanol extract from blueberry and raspberry were 88.67% and 62.77%, 76.34% and 30.53% at a concentration of 5 mg/mL. The 80% methanol extract from blueberry and raspberry showed considerable antioxidative activity against reducing power in dose-dependent manner. Antioxidative activities using $\beta$-carotene-linoleate and FTC method were twice higher in blueberry than raspberry.

Berry fruits are rich in phytochemicals, including polyphenols, anthocyanins, phenolic acids, and organic acids, which are known to have beneficial effects on health. The aim of this study was to investigate chemical composition, functional constituents, and antioxidant activities of mulberry, black raspberry, raspberry, and blueberry cultivated in Korea. Acidity of the four berries ranged from 0.26% to 1.10%, and pH ranged from 3.3 to 5.2. Total mineral contents of the four berries ranged from 92.9 to 256.0 mg/100 g. Among the berries, mulberry contained the most abundant total free sugars, and glucose and fructose were the major sugars in the berries. Mulberry contained more than three times as much ${\gamma}-aminobutyric$ acid as the content of the other berries. Blueberry contained more free phenolic acid than the other berries. Especially, chlorogenic acids were the major free phenolic acids in blueberry. Black raspberry had the highest amount of polyphenols, anthocyanins, and flavonoids among the berries and showed the highest antioxidant activity.

This study was performed to evaluate and compare the antioxidant and antimicrobial activities of various berry juices (cherry, grape, blueberry, aronia, cranberry, and raspberry). The cherry, aronia, and cranberry juices included higher levels of total polyphenol than the other berry juices. The DPPH radical scavenging activity of various berry juices increased according to the juices concentration. The scavenging activity of DPPH radicals by the aronia, cranberry, and raspberry juices was higher than those of other samples and was in the following order: aronia > cranberry > raspberry. The FRAP values of 100% aronia juice was the highest among the samples, which was more than five times higher than grape juice at a concentration of 25%. The cranberry and raspberry juices exhibited a strong inhibitory effect against important food-borne bacteria, and in general, the berry juices inhibited the growth of Gram-negative bacteria more than that of Gram-positive bacteria. The cranberry and raspberry juices exhibited high antimicrobial activities against important food-borne bacteria at a concentration of 100% and 75%, however, they did not affect food-borne bacteria at a concentration below 10%. These results suggest that aronia, cranberry, and raspberry may be used effectively as natural additives and as functional foods due to their high antioxidant and antimicrobial activities.

베리류 과수 가운데 블루베리, 아로니아, 복분자, 오디, 산딸기, 라즈베리 등 6종의 에탄올 추출물을 이용하여 총 폴리페놀 함량을 측정하고, DPPH법을 이용하여 항산화 활성을 측정하여 상호간 상관 관계를 분석하였다. 총 폴리페놀 함량은 아로니아> 복분자> 오디> 블루베리> 라즈베리> 산딸기 순으로 나타났으며, 항산화 활성은 아로니아> 라즈베리 >복분자> 블루베리> 오디> 산딸기 순으로 나타났다. 이러한 결과로 총폴리페놀 함량과 항산화 활성과의 상관관계가 있다는 것을 확인하였으며, 그 중에서도 아로니아와 복분자가 강력한 항산화 활성이 있는 것으로 나타났다. 그러나 라즈베리의 경우는 총폴리페놀 함량이 낮은데도 불구하고 항산화 활성이 높았다. 따라서 앞으로 라즈베리에 대한 선행연구가 필요하리라 생각된다. 이와 같은 결과들로 미루어 볼 때, 6종 베리류(블루베리, 아로니아, 복분자, 오디, 산딸기, 라즈베리) 에탄올 추출물은 농도 의존적으로 항산화 활성에 대한 효과가 양호하였으며, 이러한 연구결과들을 활용하여 트러블, 염증 억제제 및 항균활성으로 기능성 화장품의 신소재 개발이 가능하다고 판단된다.

Atmospheric icing may have significant effects not only on safety of aircraft in air, but also on performance of wind turbine and power networks on ground. Thus, ice protection measure should be developed to protect these systems from icing hazards. A very efficient method is the electro-thermal de-icing based on a process by which ice accretion is melted and blown away through aerodynamic forces. In this computational study, a state-of-the-art icing code, FENSAP-ICE, was used for the analysis of electro thermal de-icing system. Computational results including detailed conjugate heat transfer analysis were then validated with experimental data. Further, the computational model was applied to the DU21 airfoil section of NREL 5MW wind turbine with calculated heater parameters.

This article examines some important issues in films about new religious movements (NRMs) that express and represent NRMs in sensationalistic ways and criticize them as immoral and antisocial cults. I presented a typology to analyze films about NRMs from the perspective of marginalized religions separated from established religions and also as alternative religions that replace the established religions. In recent times, films about NRMs have changed from being social criticisms that represents NRMs as perpetrators of brainwashing and the need for deprogramming to that of faithful participation and empathetic reflection. Films about NRMs that utilize empathetic reflection, including Wild Wild Country (2018), go beyond the normative, single-perspective formula to enable insiders to conduct self-reflection and outsiders to empathize through openness, varied perspectives with multi-faceted composition and polyphony. In contrast, films about NRMs that adopt the perspective of faithful participation, including The Road to Peace (1984), present a new visual way to unravel the voices of silenced subalterns with alternative religious visions and those who needed relief from the marginalization due to alienation or exclusion from established religions. In the Korean context, these visions are expressed as 'the great transformation into the creation of a paradise of the Later World (後天開闢)' or as 'the resolution of grievances for mutual beneficence (解冤相生).'

Bulhwangeumjeonggisan (BHGJGS) is a traditional herbal formulation generally used in the treatment of cold and gastritis. BHGJGS consists of eight herbal plants; Atractylodis Rhizoma, Magnoliae Cortex, Citri Pericarpium, Glycyrrhizae Radix, Agastachis Herba, Pinelliae Rhizoma, Zingiberis Rhizoma and Zizyphi Fructus. Complete standardization of this formulation has not been done yet. So, a simple and accurate method was developed and validated using Ultra Performance Liquid Chromatography (UPLC) with Diode Array Detector (DAD) for the standardization of BHGJGS. UPLC conditions were optimized using a c18 RP-Amide column with mobile phase; 0.1% phosphate buffer and acetonitrile, detection wavelength; 210 and 325 nm. The linearities of calibration curves were acceptable ($R^2$>0.9994), and the limit of detection and quantification were within the ranges of 0.011-0.091 and $0.034-0.277{\mu}g/ml$ respectively. The relative standard deviation (RSD) of intra- and inter-day precisions were under 3.61%. The RSD of repeatability was under 0.68 %. The results of recovery test were 94.4-107.9%, and the RSD were under 4.6%. The developed method was used to find the contents of standard constituents in BHGJGS mix extract powder, and two commercial formulation (A and B). The data show that the developed method was specific, sensitive, accurate, and precise for analysis of BHGJGS components.
