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.

This study attempted to find out how much stress Dental Technicians of working in Dental Laboratory have built up in the midst of their daily lives are according to their sex, age, duration of work and their kinds of positions. After self-administered questionnaire were distributed by direct to 230 technicians samplely selected from dental laboratories in Seoul and Pusan of whom 163 technicians responded from october 1 through october 13, 1994. Analysis of the data was processed by t-test, $X^2$-test, ANOVA. This results are as follows. 1. Levels of Stress of the total 163 respondents by sex is not higher among male than female(p>.05). 2. Levels of stress - 36.2%(74 Dental technicians) of all Dental technicians were in stress on the whole and 9.2%(15 Dental technicians) of them were in a serious situation by accumulated stress. 3. Realization of stress - 10.1%(16 Dental technicians) of the dental technicians and 89.9%(143 Dental technicians) were found out to be in a dangerous sign or in a situation by accumulated stress. Further studies which a big size and a delicate method of measuring their general characteristics are needed.

Computerized Sperm Motility Analyzer를 이용한 Human Sperm의 Hyperactivated Motility의 객관적 관찰에 관한 연구
이희경,이찬,김현숙,김영태,김선행,구병삼,Lee, Hee-Kyung,Lee, Chan,Kim, Hyun-Sook,Kim, Young-Tae,Kim, Sun-Haeng,Ku, Pyoung-Sahm 대한생식의학회 1994 Clinical and Experimental Reproductive Medicine Vol.21 No.1
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.

도시 문명에 갇힌 인간 소외와 상실감 : 최인호의 「타인의 방」을 중심으로
이희경(Hee Kyung Lee) 동서언론학회 2012 동서언론 Vol.15 No.-
The 1970s, which is the background for Choi Inho's novels, was when the Korean economy started making visible progress after it was totally crumbled by the Korean War. The new generation's pursuit of material values ended up with conflicts with the older generations that believe the mental values, such as the traditional customs and the proprieties certainly outweigh the material ones. The 1970's literature that emerged during this transition period was focused on describing the contemporary people dealing with the contradictory realities attributed to the abrupt modernization, implying both positive and negative outlooks. Choi Inho's literature was a literary correspondence to this contradictory period. This study reviewed Choi Inho's "The Room of a Stranger (1971)", compared to Park Wanseo's "Resembled Rooms (1971)" and Lee Dongha's "Hongso (1974)", to look into the changes in people's way of life that were influenced by the emergence of the apartment, considered as a modernized, private dwelling space. The reasons for choosing these books were to see how the 70's economic growth and its consequential modernization and urbanization influenced people's way of life. It also aimed to find out how the contemporary writers touched those issues in their works. The three books well portray the inner struggles of man against isolation, alienation, competitive ambition, and deviant desire that were undergone in the process of joining the "world" symbolized by the apartment. All three books commonly talk about city people's weariness, anxiety, sense of being different from others, loneliness, loss of personality, blind faith in material values, and criticism of consumer culture, and the description of a family that unveils the changes in traditional values and the collapse of patriarchy. Overall, these books criticize the modern life and long for the traditional values and old-day culture represented by patriarchy. The early 70s was when the construction of apartment complexes, initiated in the 60s, was beginning to boom and becoming popular. In his "The Room of a Stranger," Choi Inho talks about the isolation in relationships, loneliness, and the confusion with regards to one's identity as represented by the "apartment life." Although Choi Inho's book seems less realistic compared to Park Wanseo's "Resembled Rooms" that describes the lack of individuality, which is a typical phenomenon in the modern life, and the consumption desires that resulted from the blind faith in material civilization from a female perspective and Lee Dongha's "Hongso" that shows the antagonism to uniform culture and isolation, the awareness of collapsed patriarchy, and the criticism of a family being addicted to consumption in the apartment life, his book rather appears to take one step closer to the intrinsic problems of the urban life. That is, "The Room of a Stranger" is a book that comprehensively shows ongoing alienation and loneliness along with its inherent boredom caused by urbanization.
