研究室紹介
Professor Jeong-Eun Park's research lab specializes in food science, cosmetic safety, and environmental microbiology, with a focus on functional food development, the optimization of food formulations, and the safe use of preservatives in personal care products. The lab investigates bioactive compounds in natural sources—such as Stevia and Hwangdo peach—for their health-promoting effects, while also advancing analytical methods for trace contaminant detection in cosmetics and food systems. Additionally, the lab explores the ecological and physiological parameters of microalgae used in aquaculture, contributing to sustainable seafood production. These interdisciplinary efforts reflect a strong commitment to health, safety, and sustainability in food and cosmetic science.

15This study investigated the effects of Stevia rebaudian bertoni leaf extract on lipid profiles in C57BL/6J mice, as compared to stevioside. Fourty mice were divided into four groups: NC (normal diet and DW), HC (high fat diet and DW), HLSV (high fat diet and stevia leaf extract, 1 mL/kg/day), and HSS (high fat diet and stevioside, 1 mL/kg/day). Serum triglyceride concentrations were significantly lower in the HLSV and HSS groups than in the HC group. Epididymal fat pad weights were significantly
본 연구의 목적은 한국 사회에서 캠핑활동에 관한 담론들이 기존의 가족담론을 어떻게 강화, 유지, 변화시키는 지를 이해하는 것이다. 이를 위해 캠핑에 관한 기획기사를 대상으로 비판적 담론분석을 실시하고, 실제 캠핑활동 참여자들을 대상으로 하는 수용자 조사를 통해 담론분석의 정합성을 높이고자 하였다. 분석결과, 캠핑에 관한 기획기사의 에피소드들은 가족위기 담론과의 결합을 통해 가족문제와 현대가족의 현실에 대한 대안으로 제시되고 있으며, 이러한 담론의 구성은 가족여가에 대한 이상화된 시각과 가족신화 이데올로기가 함께 반영된 것이다. 또한 캠핑문화에 내재되어 있는 가족담론들은 돈과 시간이라는 물적 조건을 확보한 중산층 가족을 전제하며, 동시에 남성성과 성 역할 고정관념에 관한 젠더 이데올로기가 내재되어 있어 ‘남성’이 부재하는 가족을 배제시키고 정상가족 이데올로기를 지지하게 된다. 실제 수용자들 역시 캠핑활동에는 ‘남자’가 필요하며, ‘남자의 역할이 크다’는 전형적 이미지로서 여가고정관념을
The purpose of this study was to demonstrate the changes in structure and contents of different functional genre of science writing during high school using the argumentation structure. For this thesis, seven students of a girls' high school in the national capital region took the argumentation structure instruction for 40 hours for a month. As a result, considerable changes had occurred amid the Explanation genre, the Experiment-recount genre and the Exposition genre. In the Explanation genre a
미생물의 오염을 통해 화장품이 변질되거나 분해되는 것을 방지하여 소비자를 보호하기 위해 화장품에 보존제가 사용된다. 파라벤류는 제형화하기 쉽고, 활성 범위가 넓으며, pH에 화학적으로 안정하면서 저렴하여 거의 모든 종류의 화장품에 널리 사용된다. 페녹시에탄올과 클로페네신 역시 화장품에 일반적으로 사용되는 보존제로 보통 파라벤과 함께 사용된다. 파라벤의 독성은 일반적으로 낮지만, 손상된 피부에는 자극을 유발할 수 있으며, estrogenic 잠재성, 마취 효과 및 생식 독성의 가능성에 대한 논란이 있어 왔다. 따라서 파라벤은 배합한도 원료로 지정 관리되고 있으며, 페녹시에탄올과 클로페네신도 마찬가지로 최대 허용량이 지정되어 있다. 그러므로 제품 중 보존제의 함량을 관리하는 것은 중요하다. 그러나 일반적으로 사용되는 역상 액체크로마토그래프법으로는 이성질체를 포함한 6종의 파라벤과 페녹시에탄올 및 클로페네신을 동시에 분리 분석하기 어려웠다. 용출 시간이 길어져, 피크 모양이 나쁘고 분리능
Optima for temperature, salinity and light intensity for Nitzschia closterium, Chlorella saline Isochrysis galbana and Tetraselmis subcordiformis, which are widely used in bivalve hatcheries of Shandong Province in China, were estimated. The temperaure optimum was 23℃ for N. closterium and I. galbana, and 25 and 27℃ for C. salina and T. subcordiformis, respectively. That for salinity was 23‰ for N. closterium and T. subcordiformis, but was 33‰ for C. salina and I. galbana. In general, all the fo
This study is aimed at grasping the actual status of education site in preparation for the change in the educational environment by ubiquitous computing and subsequent attitudes of teacher and student who are the actual users. Questionnaire survey was conducted against teachers and students who are the users as well as site survey through the visit to u-School Research School. The results are as follows; (1) In case of frequency for the teacher’s use of the equipment during lesson, the ratio of
This study was conducted for the optimization of ingredients in salad dressing using Hwangdo peach (Prunus persica L. Batsch). The experiment was designed according to the D-optimal design of mixture design, which included 14 experimental points with 4 replicates for three independent variables (olive oil 40~65%, peach puree 27~50%, vinegar 8~20%). The linear regression models for pH, viscosity and color value and the quadratic regression models for emulsion stability, all sensory evaluation of
This study aimed at investigating heritage language competence of missionary kids(MK) and variables influencing competence. Data came from 93 students of two missionary schools in Philippines: One is Korean Academy(KA), and the other is International Academy(IA). To meet the goal, the study examined grammatical and pragmatic competence by grammatical judgment test(GJT) and acceptability judgment test(AJT). The study found out that there was no difference in pragmatic competence, but meaningful d
