In this study, a survey was conducted with managers of small-size skin care salons regarding awareness of emotional marketing, which contributed to booming of the coffee industry, in order to find a way to activate the small-size skin care market. Awareness and importance of emotional marketing and five-sense (sight, smell, hearing, tasting, emotion) marketing was surveyed and compared by 178 managers of skin care salons in Seoul, Daegu, Gwangju, and Jeju, and frequency analysis was performed according to the highest educational attainment, management experience, size of salons, and monthly income. The result shows that, among the five senses in the emotional marketing, visual marketing showed the highest awareness (77%), and emotional marketing had the highest influence on the revenue (83.7%). In terms of awareness of emotional marketing according to the educational background and management experience, subjects with higher education and longer management experienced were more aware of emotional marketing, and people who were more aware of emotional marketing had higher monthly income. Longer management experience and larger size of the salon was correlated to higher awareness of visual marketing. In conclusion, this study suggests that higher awareness of emotional marketing and visual, olfactory, auditory, gustatory, and emotional marketing can improve revenue and generally help the managers of skin care salons. The author hopes that this study will provide solution to problems experienced by small-size skin care salons and foundation to activate the skin care industry.

Effects of Basil and Majoram Essential Oils with or without Ascorbic Acid on Color and Oxidative and Microbial Stability of Beef Patties

정해정 한국식품영양과학회 2004 Preventive Nutrition and Food Science Vol.9 No.1

Fresh ground beef was mixed with ascorbic acid, basil essential oil, majoram essential oil, or each essential oil combined with ascorbic acid and stored at 1±1oC for 7 days. Color, lipid oxidation (TBARS formation), aerobic bacterial counts and pH were determined. Basil and majoram essential oils were effective in inhibiting color deterioration, lipid oxidation and bacterial growth. The combined addition of basil and ascorbic acid showed the highest protection against color fading, followed by majoram+ascorbic acid, and ascorbic acid alone. Basil and majoram essential oils were most effective in delaying TBARS formation (p<0.01). Ascorbic acid did not exert an antioxidative effect and even exhibited a pro-oxidant effect. The pH values of all samples increased slightly, but no significant differences were observed, either among treatments or throughout the storage time (p>0.05).

사드(THAAD)의 한국배치와 美中 우주군사 전략과의 상관성 연구

정해정 한국중국문화학회 2018 中國學論叢 Vol.0 No.60

This paper aims to verify that the space race between the U.S. and China, which has been intensified since 2000s, is one of main reasons which caused two nations’ confrontation on the deployment of THAAD in Korea. Previous researches conducted after the deployment of THAAD in Korea are mainly focused on the military utility of THAAD in defending North Korea’s missile attack, or South Korea’s effective diplomatic strategies based on the analysis of the development process of the U.S.-China hegemonic competition. On the other hand, this paper, on the basis of critical analysis and assessment of existing research results, expands the research scope for the deployment of THAAD in Korea into outer space and suggests a more three-dimensional cause analysis and future prospect for the THAAD conflict among South Korea, the U.S., and China. Therefore, this paper eventually contributes to South Korea devising more effective strategic measures to resolve the THAAD conflict. 본 논문의 목적은 2000년대 이후 강화되고 있는 미국과 중국의 우주군사 개발과 상호 경쟁이 사드의 한국배치에 대한 美中간 대립의 핵심적인 원인임을 증명하는 것이다. 사드의 한국배치를 전후하여 현재까지 이루어진 연구들은 주로 사드의 북한 미사일 방어에 대한 군사적 효용성 여부에 집중하거나, 혹은 美中간 패권경쟁의 원인과 이의 심화 과정을 분석한 후, 이 과정에서 향후 한국이 지향해야 하는 효과적인 외교전략을 도출하는데 주력하고 있다. 그러나 본 논문은 이러한 기존의 연구성과들에 대한 비판적 분석을 바탕으로 하여, 사드의 한국 배치에 대한 연구視野를 우주공간으로까지 확대시킴으로써, 韓美中간의 사드 갈등에 대한 보다 입체적인 원인분석과 향후 전망을 제시하는데 기여할 것이다.

정해정,이기열,유석종,심재찬,이기재,김호균 대한영상의학회 2002 대한영상의학회지 Vol.46 No.4

엽외 폐분리증은 기관지폐 분리증의 드문 유형으로, 기능을 할 수 없는 폐실질의 일부가 자신만의 늑막으로 둘러싸여 있고, 체동맥으로부터 혈류공급을 받는 선천성 기형이다. 저자들은 비정형적 양상을 보인 엽외 폐분리증 1예를 보고하고자 한다. 전산화단층촬영상 종괴는 우측주엽간열 내에 위치하는 조영증강이 되지 않는 고밀도 병소로 관찰되었다. 수술소견상 폐동맥분지로부터 혈액공급을 받고 좌심방으로 유출되는 정맥을 갖는 종괴로, 병리소견상 엽외 폐분리증으로 확진되었다. Extralobar pulmonary sequestration, a rare form of bronchopulmonary sequestration, is a congenital anomaly in which a portion of nonfunctioning lung tissue is surrounded by its own pleura and is supplied by a systemic artery. We describe a case of extralobar pulmonary sequestration with unusual features. CT scanning of the chest demonstrated a non-enhancing, hyperdense mass within the right major fissure, and thoracotomy revealed that the mass received blood from a branch of the right pulmonary artery and drained into the left atrium. The pathologic diagnosis was extralobar pulmonary sequestration.

손바닥 선인장의 항산화 및 항균특성

정해정 한국조리과학회 2000 한국식품조리과학회지 Vol.16 No.2

손바닥 선인장 열매를 극성을 달리하는 여러 용매로 추출하여 항산화력과 항균력을 측정한 결과 95% ethanol과 methanol을 사용하였을 때 우수하게 나타났고 ethanol 추출물의 항균활성은 그람음성균보다 그람양성균에서 효과적이었다. 농도별 항균력시험 결과 추출물의 농도가 증가할수록 비례하여 저해율도 크게 증가하였고 열에 대한 안정성 시험에서는 40∼120℃의 범위에서는 안정하여 동일한 항균력을 유지하였으나 160℃ 이상에서는 그 활성이 상실된 것으로 나타났다. 추출물의 첨가농도를 달리하여 미생물의 생육도를 측정한 결과, 그람양성균은 3.0∼4.5㎎/㎎의 첨가 범위에서 증식이 억제되었으나 그람음성균은 본 실험에서 사용한 첨가농도로는 완전한 증식억제효과가 나타나지 않았다. 손바닥 선인장 ethanole 추출물을 hexane, chloroform, ethyl acetate, butanol 및 water 등의 용매로 순차 분획하여 항균활성을 측정한 결과 ethyl acetate분획이 효과가 가장 큰 것으로 검색되었다. The extracts of Opuntia ficus indica var. saboten were obtained by using seven solvents of increasing polarity and their antioxidative and antimicrobial activities were investigated along with thermal stability. The highest antioxidative activity expressed as electron donating ability and antimicrobial activity were observed in the 95% ethanol extract. Cell growth inhibition was not apparent on Escherichia coli, Pesudomonas aeruginosa and Salmonella typhimurium, but was great on Bacillus subtilis, Micrococcus luteus and staphylococcus aureus at the level of 4.5 ㎎/㎎ medium. The ethanol extract of Opuntia ficus indica var. saboten showed the thermal stability in the range of 40∼120℃. It was re-extracted sequentially with hexane, chloroform. ethyl acetate, butanol, and water, among which ethyl acetate fraction showed the highest inhibitory effect against Bacillus subtilis, Micrococcus luteus and Escherichia coli.

추출용매에 따른 아사이 베리의 생리활성

정해정 한국식생활문화학회 2012 韓國食生活文化學會誌 Vol.27 No.1

This study was conducted to investigate the physiological activity of acai berry (Euterpe oleracea Mart.) extracts from three different solvents (water, methanol, and ethanol). We measured total polyphenol and total flavonoid content, DPPH radical scavenging activity, nitrite scavenging activity, metal chelating effect, and reducing power. The extraction yield from water,methanol, and ethanol was 17.10, 9.50, and 37.51%, respectively. The highest total polyphenol content (10.54 mg/100 g)and total flavonoid contents (1.88 mg/100 g) was observed in water extract. DPPH radical scavenging activity was the highest in both water extract (72.03%) and methanol extract (74.79%) at levels of 5 mg/mL, which was similar to that of BHT (78.90%). Water extract yielded the highest metal chelating effect (92.54%) and reducing power (1.09) at levels of 5mg/mL. Taken together, these findings suggest that extracts of acai berry can be used as functional food materials with antioxidative and nitrite scavenging activities.

Influence of Purple Sweet Potato Powder Addition on the Quality Characteristics and Oxidative Stability of Cookies

정해정 한국식품영양과학회 2009 Preventive Nutrition and Food Science Vol.14 No.1

Cookies were prepared by adding different levels (0, 5, 10, 15, and 20%) of purple sweet potato powder (PSPP) and their physicochemical and sensory characteristics were examined. With increase of the PSPP level, moisture content decreased and ash content increased (p<0.05). The spread factor of control cookies was higher than that of cookies containing PSPP. The incorporation of PSPP in cookies lowered the lightness and yellowness but increased redness (p<0.05). Texture measurement showed that the addition of PSPP did not affect the hardness of cookies. Results of acceptance test revealed that overall acceptability score was not significantly different between the control and the PSPP added cookies. Therefore, it is suggested that PSPP can be incorporated into cookies up to 20% without affecting the cookie quality. Total polyphenol content and antioxidant activity were assessed to examine the functionality of cookies. In addition, substitution of wheat flour with PSPP yielded cookies with higher polyphenol content and antioxidative activity (p<0.05). The peroxide value (POV) and acid value increased during storage at 60oC for 80 days. The POV was significantly lower in cookies containing PSPP than the control cookies, suggesting that the addition of PSPP deterred the lipid oxidation (p<0.05).
