      • Highly sensitive, selective bioelectronics nose that mimics the human nose

        Ye Rim Mun,Oh Seok Kwon 한국진공학회 2021 한국진공학회 학술발표회초록집 Vol.2021 No.2

        Among various human sensory system, due to the complexity of olfactory sensory neurons, it is difficult to make achievement in mimicking human nose. Herein, we demonstrated an artificial multiplexed bioelectronic nose combining the olfactory receptor on uniform graphene micropatterns (GM). Utilizing the transistor, target odorants were monitored with high selectivity and sensitivity (minimum detectable level: 0.1 fM)

        Realtime PCR법에 의한 청소년의 치아우식 유발세균 감염률 조사

        문예림 ( Ye-rim Mun ),박지현 ( Ji-hyeon Park ),조자원 ( Ja-won Cho ),김우람 ( Woo-ram Kim ) 대한예방치과·구강보건학회 2020 大韓口腔保健學會誌 Vol.44 No.2

        Objectives: The aim of this study was to investigate the infection rates of bacteria associated with dental caries among children and adolescents in Korea. Methods: Oral examinations were conducted in 146 students. The numbers of bacteria associated with dental caries, such as Streptococcus mitis, Streptococcus mutans, Streptococcus sobrinus, and Lactobacillus casei, in the subjects’ oral cavity were counted by real-time PCR, and infection rates for those bacteria were additionally investigated. Results: The infection rate of Streptococcus mitis, Streptococcus mutans, Streptococcus sobrinus, and Lactobacillus casei was 99.3% (145/146), 63.0% (92/146), 1.4% (2/146), and 25.3% (37/146), respectively. The amounts of Streptococcus sobrinus and Lactobacillus casei did not differ with the participants’ age. However, the number of Streptococcus mutans was 537.6 for primary school students, 5698.2 for middle school students, and 19037.5 for high school students. The mean number of oral bacteria increased with age (P<0.05). The mean bacterial numbers of the infected subjects indicated significant differences in the numbers of Streptococcus mitis and Streptococcus mutans (P<0.05). Conclusions: The infection rates of Streptococcus mitis and Streptococcus mutans were distinct in children and adolescents. Efforts to control the bacteria associated with dental caries are needed to prevent dental caries.

        염화세틸피리디늄 및 아세트산 아연을 함유한 구강 양치액의 효과

        문예림 ( Ye-rim Mun ),최길복 ( Gil-bok Choi ),김다희 ( Da-hui Kim ),조자원 ( Ja-won Cho ),예재승 ( Jae-seung Yea ) 대한예방치과·구강보건학회 2023 大韓口腔保健學會誌 Vol.47 No.2

        Objectives: This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health. Methods: A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared. Results: Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P<0.05). Measurements of the PHP and Turesky plaque indices showed a significant difference in the experimental and control groups after 4 weeks (P<0.05). Compared to the PHP index before the experiment, that of the experimental group showed a significant index decrease after 2 weeks (P<0.05). Results of measuring bad breath through a BB checker showed a statistically significant difference between the experimental and control groups after 4 weeks (P<0.05). Conclusions: Oral mouthwash products containing cetylpyridinium chloride and zinc acetate relieves gingivitis, removes bacterial plaque, and reduces bad breath.

      • 아동 친화적인 놀이 특성을 고려한 ‘서울형 키즈카페’ 사례 연구

        문예림(Mun, Ye-Rim),노신웅(Noh, Shin-Woong),박소희(Park, So-Hee),황연숙(Hwang, Yeon-Sook) 한국실내디자인학회 2024 한국실내디자인학회 학술대회논문집 Vol.26 No.1

        As women’s opportunities for economic activities expand and the number of nuclear families increases, the burden of caring for children also grows. Consequently, there is a rising demand for indoor play spaces where children are able to develop in a safe and healthy environment, while their parents are at work. In response, the Seoul Metropolitan Government initiated the operation and support of the ‘City-Run Kids Cafe’ in 2022 to ensure that children’s fundamental ‘right to play’ is protected. However, there are no standards for the kids cafe created by Seoul City, and so this study aims to present insightful data and direction for improving public indoor play spaces. The method of this study is as follows: First, our study examined the differences between private and public types of play spaces using academic literature on indoor play spaces. Second, the characteristics of child-friendly indoor play spaces were derived through theoretical analysis of children’s play environments. Finally, a conclusion was drawn by presenting the space-specific characteristics of the ‘City-Run Kids Cafe’ through field research. As a result of this study, it was confirmed that among the five characteristics, ‘Amenity’, ‘Safety’, and ‘Playfulness’ were the most evident. However, ‘Diversity’ with play considering the age of children and ‘Physicality’, necessary for free movement, were found to be lacking, suggesting that improvements are needed.

      • 지역정체성을 고려한 도시재생 문화공간의 맥락적 디자인 특성에 관한 연구 - 서울시 비전2030, 근현대건축자산을 활용한 문화공간 조성을 중심으로 -

        강지연(Kang, Ji-Yeon),문예림(Mun, Ye-Rim),고홍국(Gao, Hong-Guo),황연숙(Hwang, Yeon-Sook) 한국실내디자인학회 2023 한국실내디자인학회 학술대회논문집 Vol.25 No.3

        The city of Seoul carried out Vision 2030, Culture Citizen City Seoul to rejuvenate old facilities and unused spaces and transform them into cultural venues. The city did so by leveraging modern and contemporary architectural assets to promote the cultural characteristics of the local area in urban revitalization. During this process, contextual design played a pivotal role. The objective of this study is to investigate cases of the regeneration of modern and contemporary architectural assets from a contextual design perspective and provide a design direction to enhance future value within the local community. The theoretical concepts related to regional identity and contextual design in urban revitalization were investigated and used to derive characteristics and analytical frameworks based on prior research. On-site investigations for selected case studies were used in order to draw conclusions. Our results are as follows. In the restoration and enhancement of modern and contemporary architectural landmarks, the preservation of historical significance achieved through the establishment of exhibition spaces, was prominently observed. The project effectively conveyed the unique stories of the local area through exhibitions or experiential programs, while providing an accessible cultural infrastructure. Further to this, the revitalization was achieved through a harmonious design that did not disrupt the surrounding environment. However, there was a need for spaces to enhance community engagement among local residents and visitors.
