홍다검ㆍ이희경ㆍ이정현(Da Geom HongㆍHee kyung LeeㆍJeong Hyun Lee) 한국인체미용예술학회 2016 한국인체미용예술학회지 Vol.17 No.1
Recently, nail industry trends have been shifting from polish nail to gel nail. Because of the popularity of gel nail, the criteria for customers to choose colors have significantly changed. Therefore, there has been a rising demand for a nail color which goes well with skin color, not with the color of clothes, makes the hand more beautiful. Unlike a face, hand skin color isn’t corrected through makeup. Therefore, it is more difficult to find a color which is well matched with the skin tone. In this sense, the accurate analysis and classification of hand skin color which is the first step in the selection of nail color are required. However, it’s still very hard to find studies on hand skin color. To figure out the characteristics of Koreans’ hand skin color by age, this study analyzed differences in hand skin color by age after measuring the tone of the back of the hand and conducting quantitative analysis against 300 women living in Busan, Ulsan and Gyeongnam. The results revealed statistically significant difference (p.001). As the respondents were younger, a bright skin tone was observed. According to analysis on the distribution by the rank, ‘20s’ was the highest with 46% among those with a bright skin tone within top 100 ranks. In top 300 ranks, in contrast, ‘50s’ was the highest with 46% while ‘20s (8%)’ was the lowest. In terms of a skin tone, there was a considerable difference between ‘20s’ and ‘50s.’ Even though no big difference was found between ‘30s’ and ‘40s,’ a skin tone was brighter in the latter.

The occurrence and time course of capacitation, acrosomal loss, and hyperactivated motility require quantitative definition in order to characterize fertile human sperm. Recently the method has been developed to estimate the quality of spermatozoa by using kinematic parameters such as curvilinear velocity(VCL), average path velocity(VAP), linearity(LIN), straightness(STR), amplitude of lateral head displacement(ALH), and beat cross frequence(BCF) from Computer Assisted Sperm Analysis (CASA). In this study, using the Hamilton Thorn motility analyzer HTM 2030(Hamilton Thorn Research, Beverly, MA), we attempted to identify the spermatozoa with hyperactivated motility (HA) objectively and to monitor hyperactivation of human spermatozoa during incubation in capacitating media and after treatment of calcium ionophore as compared with acrosome status. And we examined whether HA are related to the result of SPA. Semen samples obtained from 16 healthy men were prepared by swim up technique and preincubated in a capacitating media(modified BWW medium) for 5 hours and treated with calcium ionophore solution. The acrosome reaction was detected with PSA-FITC labelling of the acrosome and in vitro sperm ferilizing capacity was assessed by the zona free hamster ovum penetration assay (SPA). The incidence of hyperactivated sperm was 2.6% in fresh semen, 14.3% of the swim up population, 13.7% after 5h of incubation. Significant increase of percentage of hyperactivated sperm was observed after the incubation (p<0.05) but after treatment, no significant changes of percentage of hyperactivated sperm(l1.8%) in contrast to significant rise in the percentage of acrosome reacted cells. Correlation analysis failed to show any significant relationship between the percentage of sperm with HA and SPA score. In conclusion, although no direct correlations were found between the results of SPA and HA, hyperactivation of sperm is associated with capacitation and monitoring hyperactivated sperm will be expected as a method of evaluating the functional quality of sperm such as SPA.

Purpose: This study was conducted to corroborate factors affecting dental technicians recognition states of their job consciousness. Methods: Self-administering questionnaires were distributed directly to some 200 registered female dental technicians in metropolis, small & medium-sized cities, farming and fishing villages of whom 153(76.5%) female dental technicians and female students responded in December, 2009. Information on recognition states of female dental technicians and female students in department of dental technology possible occupational mind and other general characteristics was gathered. Analysis of data was processed by use of X2-test and multiple regression analysis. Results: The recognition states of occupational satisfaction were higher in female students than female dental technicians(p<.05). They were observed that between respondents with more than five years of work and less than five years of career(p<.05). Statistically significant differences were observed in recognition values of female dental technicians occupational satisfaction between high and low groups of internal characteristic of their position and all ceramic part(p<.05). Conclusion: For woman dental technicians, the most predictive variables for recognition values of occupational satisfaction were an age, between groups, which of part and career(p<.05). Finally, this result suggests the facts that in order to achieve self-realization through the work experience, women herself should get rid of the dichotomous diagram and should change the consciousness of traditional role normals.

This study was investigated the contents of total polyphenol, flavonoids and antioxidant and antimicrobial activities of Codonopsis lanceolata extracts according to different steaming times. The contents of total polyphenol and flavonoid proportionally increased from 6.45 mgGAE/g to 18.26 mgGAE/g and 2.01 mgRE/g to 6.12 mgRE/g according to ethanol extracts at EDS7. DPPH radical scavenging activity was found to have been 15.26~65.2% and showed the highest level of antioxidant activity at EDS7 was 65.2%. The activity of ABTS radical scavenging and SOD-like activity were also the same result. DPPH and ABTS radical scavenging activity was related to the number of steaming, and the scavenging activity was increased up to 7 times of steaming. The antimicrobial activity of EDS7 had strong antioxidant activity. Antimicrobial activities were examined against 5 microorganisms related to pathogens and food poisoning. The antimicrobial Activity was different depending on the bacteria, but it was effective at the concentration of 300 mg/mL rather than 150 mg/mL. These results showed that Codonopsis lanceolata extracts with a different number of steaming would be conducted to confirm the possibility of developing antimicrobial and antioxidant. It will be helpful in the study of component analysis of Codonopsis lanceolata extracts processed products.

이희경(Lee, Hee-Kyung)(李喜卿) 대한중국학회 2020 중국학 Vol.71 No.-
사상초유의 대통령 탄핵을 경험한 한국사회에서 인터넷은 소통의 새로운 방식이자 공간의 확장으로 여겨진다. 그러나 중국의 인터넷 공간은 한국과는 사뭇 다른 방향으로 발전하고 있다. 표현의 자유보다는 ‘인터넷 주권’이 우선시되기 때문에 국가 안보를 위협하는 요소들은 모두 검열과 차단의 대상이 되고 있다. 인터넷 만리장성(Great Firewall of China)의 구축, 구글·페이스북·트위터 등 글로벌 인터넷 기업들의 퇴출과 중국 IT 기업의 부상은 중국 내 인터넷 통제가 더욱 견고해지고 치밀해지는 과정을 여실히 보여준다. 이와 동시에 중국정부는 경제발전에 핵심적 역할을 담당하는 인터넷 산업을 발전시키기 위해 적극적인 지원을 아끼지 않고 있다. 정부의 지원에 힘입어 중국은 모바일 결제 시스템, 공유경제 시장에서 타의 추종을 불허하는 성장세를 보이고 있다. 본고는 중국의 사례를 통해 인터넷 공간이 국가권력에 의해 어떻게 재영토화되는지와 공간이론으로 설명하기 힘든 중국식 가상공간의 확장을 살펴보고, 중국을 포함한 전 세계적 가상공간이 보편성을 획득하기 위해 갖추어야 할 선행조건에 대해 고민해보고자 한다. 아울러 서구 철학사와 물리학사에서 논의되어온 절대적 공간 개념 및 상대적 공간 개념이 중국의 인터넷 공간에서도 적용 가능한지를 짚어봄으로써 중국의 인터넷 공간이 지니는 특성에 대해 논의하고자 한다. The internet is considered to be a novel method of communication as well as an extension of space in South Korean society, which has experienced an unprecedented impeachment of the president. On the other hand, China’s internet cyberspace is expanding in a much different direction. As internet sovereignty is prioritized over freedom of expression, any factors that threaten national security become targets of inspection and interception. The formation of the Great Firewall of China, the dismissals of global internet businesses such as Google, Facebook, and Twitter, along with the rise of Chinese IT businesses, clearly represents the process by which the internet control is solidified and tightened in China. At the same time, the Chinese government is providing active support to grow the internet industry, which plays a critical role in economic development. On account of governmental support, China has shown unparalleled growth in the mobile payments system and the sharing economy market. This paper looks at the reterritorialization of internet cyberspace by the government power and the Chinese expansion of cyberspace, which is challenging to explain with spatial theories, and considers the prerequisites for cyberspaces around the world, including China, to obtain universality. Furthermore, it aims to discuss the characteristics of the internet space in China by examining the possibility of applying the concepts of absolute space and relative space, which have been discussed in the Western histories of philosophy and physics, to the Chinese internet cyberspace.

In the past, violations of copyright did not cause damage on a large enough scale to be perceived as violations of the copyright holder’s personal rights, and even the violators were not conscious to a high degree of the illegality of their actions. However, as the rate of internet usage grew rapidly in recent years the digital industry has grown to the extent that the importance and property value of digital contents are being widely emphasized, and the economic value has increased as well. The property damage from copyright violation has grown as correspondingly, and such violations have come to be perceived, beyond violations of personal rights, as crimes of pubic concern. Reflecting these changes, though the Copyright Act has made penalties for crimes of copyright violation offenses subject to personal complaint by the victim, there are now calls to make them offenses not subject to personal complaint. The basis for this argument is that recent violations of copyright, instead of being transitory violations by individuals, are organized and repetitive in nature, and the amount of damage is immense, requiring efficient enforcement and imposition of penalties. There are further demands that copyright violations not be subject to personal complaint following the conclusion of FTAs with the EU and the United States. The practice of a few law firms, charged with settlement from copyright holders, abusing criminal complaints to extract settlements from copyright violators who fear a criminal record, also gives weight to abolishing the subjectivity to complaint principle in the Copyright Act. In response, this paper discusses whether to maintain or abolish the offense subjective to complaint principle in the Copyright Act, then examines each penalty provision in the Act to determine whether or not to it should be an offense subject to personal complaint. As a precondition to resolving the problems discussed herein, we also review the reasons the Copyright Act established the offense subject to personal complaint principle in relation to the characteristics of copyright protection. Copyright works, beyond being a subject of the copyright holder’s personal rights, has a public aspect in forming and developing human culture through the public’s use of such works and the resulting changes in ideas and opinions and the creation of new works. Therefore, the principle of offense subject to personal complaint is appropriate so that criminal penalties only apply when the copyright holder brings a criminal complaint with the intent to have such penalties applied, and not otherwise. However, the act of repeatedly violating copyright for the purpose of profit constitutes the acquisition by a third party of the economic benefit that the copyright holder is entitled to, when this third party contributed nothing to the creation of the copyright work. The policy considerations of cultural development behind making copyright violations offenses subject to personal complaint have no application to this latter case. We therefore conclude that the amended Act is correct in penalizing repeated violations of copyright for the purpose of profit regardless of the copyright holder’s bringing a complaint.
