Hanna Jung(정한나),Hyunju Choi(최현주) 한국생명과학회 2012 생명과학회지 Vol.22 No.2

본 연구는 라벤더(Lavandula angustifolia)향이 뇌기능에 미치는 효능을 객관적인 관점에서 살펴보고자 함에 의의를 두고 뇌파 변화를 살펴보았다. 신체적으로 건강한 20대 여자 성인(28명)을 대상으로 검증된 수면장애 조사를 통하여 수면질을 조사하여 수면에 문제를 가진 대상자를 선별하고 라벤더 향기요법을 실행하여 뇌파의 변화를 분석하였다. 뇌파 전극은 10-20 국제법에 의하여 전부두(F3, F4), 측두부(T3, T4), 후두부(O1, O2), 두정부(P3, P4)에 부착하였다. 향기요법을 시행하기 전 3분, 시행 중 3분, 그리고 시행 후 3분씩 나누어서 뇌파 검사를 시행하였다. 라벤더향은 수면질이 좋은 사람(15명)에서 후두부와 두정부에서 알파파를 감소시키고, 전두부에서는 세타파와 후두부에서 베타파를 증가시켰다. 그러나 수면질이 나쁜 사람(13명)에서는 대뇌 모든 영역에서 수면 입면파인 세타파만을 증가시키는 효능이 나타났다. 따라서 라벤더향은 수면질이 나쁜 사람에게 수면을 유도하는 긍정적인 뇌기능 효능이 있음을 확인하였다. This study investigated the effects of Lavandula angustifolia (L. angustifolia) aroma on the brain electrical activity evaluated by electroencephalogram (EEG) in female adults with sleep disorders. The subjects were 28 healthy female adults and their sleep disorders were classified by the Pittsburgh Sleep Quality Index. EEG electrodes were attached at the frontal (F3, F4), temporal (T3, T4), occipital (O1, O2), parietal (P3, P4), reference, and ground regions according to the International 10-20 system. Subjects were exposed to the L. angustifolia aroma for 3 min. Results showed that L. angustifolia aroma decreased the occipital and parietal alpha powers, and increased the frontal theta power and occipital beta power in subjects with good sleep quality. On the other hand, L. angustifolia aroma increased the theta power in the all cranial regions after aroma treatment in subjects with poor sleep quality. In conclusion, L. angustifolia aroma diminishes a state of wakefulness in the brain and helps individuals to fall asleep. Therefore, L. angustifolia aroma may have beneficial effect for female adults with sleep disorders.

The Structural Equation Modeling on Health Promotion Behavior in Migrant Workers : Multi- group Analysis by Period of Residence and Nationality

Hanna Jung,Youngsuk Kim 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10

Aim(s): This study aims to verify the structural relationship among relevant variables to forecast health promotion behavior of migrant workers, and the moderating effects of residence period and nationality were investigated through multi-group analysis. Method(s): The data were collected from 298 migrant workers in 9 regions all over the country from December 2020 to March 2021. E-Health literacy, occupational stress, acculturation and social support were exogenous variables, and perceived benefits of action, self-efficacy and health promotion behavior were endogenous variables for analysis of structural model. The data were analyzed using SPSS Version 25.0, AMOS Version 20.0, and R-4.0.3. programs. Result(s): The model fit indices for the hypothetical model were appropriate: χ2=234.94(p<.001), χ2/df=3.22, GFI=.91, NFI=.88, IFI=.91, TLI=.87, CFI=.91, and RMR=.03. The twelve of total forty-two research hypotheses were statistically significant and explained health promotion behavior 58.9%. Social support was the direct biggest influence on health promotion behavior of migrant worker. Perceived benefits of action and self-efficacy played a mediating effect in the relationship among e-health literacy, social support and health promotion behavior. According to multi-group analysis, the group of migrant workers with less than 5 years had a more statistically significant effect than the group of those with over 5 years in the route from perceived benefits of action to health promotion behavior. Also, the Nepal group had a more statistically significant effect than other groups in the route from social support to health promotion behavior. Conclusion(s): To enhance the health promotion behavior of migrant workers, providing social support should be considered on the preferential basis as an important administrative strategy. Additionally, online health information should be searched, understood, and utilized to stimulate motivation so that health promotion behaviors are perceived as beneficial behaviors, and motivational strategy that can enhance self-efficacy about personal achievements by boosting social support should be applied onto intervention programs. Moreover, migrant workers with short-term residence of less than 5 years should be educated about the benefits of health behaviors so that they can continuously apply it during long-term residence and prevent a decline in the health promotion behavior. In addition, when developing mediation by utilizing social support, it is necessary to consider the cultural backgrounds of each nationality, and through this, the differences in the health promotion behavior of multinational workers can be narrowed down.

( Jung Min Bae ),( Yu Seok Jung ),( Hanna Lee ),( Ji Hun Park ),( Seung-kyung Hann ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.2

Background: Vitiligo has substantial negative impacts on quality of life in affected patients, especially with involvement of face. Special attention should be paid to facial vitiligo. Objectives: To classify facial vitiligo. Methods: A cluster analysis was performed based on the face topography with Ward’s linkage of the Euclidean distance. A total of 473 patients with non-segmental facial vitiligo were enrolled. Whole face was divided into 8 compartments including forehead, hairline, temple, right and left cheeks, periorbital area, nose, and perioral area. In addition, age of onset, involvement of other body parts, and treatment response were compared among the clusters. Results: Four clusters were identified: Cluster 1 with involvement of almost all compartments (panfacial vitiligo, n=85); Cluster 2 with involvement of mainly periorbital area, nose, and perioral area, called (centrofacial vitiligo, n=277); Cluster 3 with involvement of hairline exclusively (hairline vitiligo, n=43); and Cluster 4 with mixed involvement (mixed type, n=68). The centrofacial vitiligo was associated with the earliest onset age and the highest response rate, while the hairline vitiligo showed the oldest onset age and the lowest response rate. Conclusion: Our classification would help to identify distinctive subtypes of facial vitiligo with different etiologies.

The COVID-19 Pandemic Response System at University Level : The Case of Safe Campus Model at Ewha Womans University

Kyunghee Jung-Choi,Nackmoon Sung,Sun Hwa Lee,Misun Chang,Hee Jung Choi,Chung-Jong Kim,Nam-Kyong Choi,Hanna Kim,Yi-Jun Kim,Whanhee Lee,Hyesook Park,Eunhee Ha Ewha Womans University School of Medicine 2022 EMJ (Ewha medical journal) Vol.45 No.4

In response to the changes in the Coronavirus disease 2019 (COVID-19) epidemic situation, Ewha Womans University established Ewha Safe Campus (ESC), an on-campus infection outbreak management system, to allow students and faculty members to safely resume face-to face classes in 2022. The COVID-19 testing station, Ewha Safe Station, is the core element of ESC. Symptomatic students and faculty members perform a combo swab self-PCR test or receive a nasopharyngeal swab PCR test from experts to prevent the spread of COVID-19 through early detection and management. ESC is significant in that it detects infection risks and proactively implements preemptive measures in a university. The COVID-19 health response system model at the university level was applied for the first time in South Korea, reaching a milestone in the history of university health in South Korea. In particular, it is highly valuable that the test was free of charge, as it enabled all of the examinees to have easy access to the test through joint cooperation with the Seegene Medical Foundation. This is a successful example of cooperation between schools and private institutions for public health improvement. In the future, the direct and indirect effects of the establishment and implementation of ESC need to be evaluated and confirmed, and areas requiring improvements need to be identified in preparation for another infectious disease outbreak in the future.

여성근로자의 출산 후 휴직 사용과 이후 직장복귀에 대한 연구: 일자리특성을 중심으로

정한나 ( Hanna Jung ),윤정혜 ( Jeong-hye Yoon ) 한국여성경제학회 2020 여성경제연구 Vol.16 No.4

본 연구는 한국 여성 근로자의 출산에 따른 휴직사용과 사용 후 직장복귀 특성을 분석한다. 한국 노동시장의 구조적 특성을 반영하는 기업규모와 임금수준을 중심으로 고용보험 DB를 활용하여 분석한 결과 대기업 근로자의 출산전후휴가 및 육아휴직 사용률은 높지만 복직률은 낮았다. 제도는 갖추어져 있더라도 일-가정 양립하기 어려운 사내문화, 그로 인해 수반되는 육아문제 등을 이유로 육아휴직 사용 이후 복직이 어려운 현실을 보여주는 결과이다. 한편 고임금 근로자는 육아휴직 사용 확률은 낮지만 복직 확률은 높았다. 한편 중소기업 근로자는 휴직 사용률은 낮지만 사용을 한 경우 복직률이 높게 나타났다. 이는 출산 이전에 일을 그만 둔 근로자를 포함하고 있지 않기 때문에 이를 고려한 해석이 요구된다. 한국 출산휴가 및 육아휴직 제도의 실효성을 높이기 위해서는 한국 노동시장의 구조적 특성을 고려한 정책 설계와 집행이 요구된다. This study analyzes the use of maternity leave and the return to work after childbirth focus on the firm size and wage level using the Korean Unemployment Insurance data. The results showed that the probability of maternity and parental leave was high in the large firm workers. On the other hand, SME workers had a low rate of maternity leave and parental leave, but the return to work was high. If SME workers receive the benefits, there is a high probability that they will be reinstated without a career interruption, so it is necessary to encourage SME workers to use their leave. On the other hand, large companies seem to have difficulty in return to work because of the competitive atmosphere, the accompanying childcare problems, and the opportunity cost due to the difficulty of reinstating the place due to the place being replaced. In other words, the policy structure and execution based on the dual labor market structure of Korea will enhance the effectiveness of the maternity protection policy.

맞벌이 및 일자리 질에 따른 부모 됨과 삶의 만족에 대한 분석

정한나(Jung, Hanna) 한국교육재정경제학회 2021 敎育財政 經濟硏究 Vol.30 No.1

본 연구는 한국노동패널 20~45세 남녀 기혼자표본을 대상으로 부모 됨(parenthood)이 삶의 만족에 미치는 영향을 분석하고 자녀지출가설(cost-of-children hypothesis) 혹은 자녀보상관점(demand-reward perspective) 중 어느 것에 더 가까운 결과가 도출되는지 확인한다. 분석 결과 부모 됨은 삶의 만족을 유의하게 낮췄으며 교육수준이 높은 그룹에서 부모 됨에 따른 삶의 만족 감소 정도가 컸다. 맞벌이 가구의 부모 됨은 외벌이 가구에 비해 삶의 만족에 부의 효과를 가졌지만, 맞벌이·유자녀 가구가 외벌이·유자녀 가구가 되는 경우 삶의 만족에 부의 효과를 가졌다. 여성의 경우 무자녀였을 때는 맞벌이가 낫지만, 유자녀시 맞벌이의 삶의 만족에 미치는 부의 효과가 나타났다. 또한 남성 비정규직 근로자 및 여성 중소기업 근로자의 부모 됨에 따른 삶의 만족 감소가 컸다. 전반적으로 부모 됨은 삶의 만족에 부의 영향을 미쳤으나 가구소득구조, 일자리 질에 따라 삶의 만족을 낮추는 정도는 차이가 있음을 확인하였다. This study examines the effect of parenthood on life satisfaction of married men and women aged 20 to 45, using the Korean Labor and Income Panel Study (KLIPS). The empirical results of this paper suggest that parenthood reduces life satisfaction, especially in the group with a high level of education, the reduction is more severe. In addition, the parenthood of dual-earner households has more negative effect on life satisfaction compared to single-earner households. When dual-earner households become both single-earner households and child-children households, it also has a negative effect on life satisfaction. For women without children, dual earner households has positive effect. For women, however, the parenthood of dual-earner has negative effect. In addition, there is a significant reduction in life satisfaction of male non-regular workers or female small and medium-sized workers as they become parents. Overall, parenthood has a negative effect on life satisfaction. The result also shows that the negative effect of parenthood on life satisfaction considerably depends on the household income structure and job quality.

Activation of PPARδ counteracts angiotensin II-induced ROS generation by inhibiting rac1 translocation in vascular smooth muscle cells

Lee, Hanna,Ham, Sun Ah,Kim, Min Young,Kim, Jae-Hwan,Paek, Kyung Shin,Kang, Eun Sil,Kim, Hyo Jung,Hwang, Jung Seok,Yoo, Taesik,Park, Chankyu,Kim, Jin-Hoi,Lim, Dae-Seog,Han, Chang Woo,Seo, Han Geuk Informa Healthcare 2012 Free radical research Vol.46 No.7

<P>Angiotensin II (Ang II)-mediated modification of the redox milieu of vascular smooth muscle cells (VSMCs) has been implicated in several pathophysiological processes, including cell proliferation, migration and differentiation. In this study, we demonstrate that the peroxisome proliferator-activated receptor (PPAR) δ counteracts Ang II-induced production of reactive oxygen species (ROS) in VSMCs. Activation of PPARδ by GW501516, a specific ligand for PPARδ, significantly reduced Ang II-induced ROS generation in VSMCs. This effect was, however, reversed in the presence of small interfering (si)RNA against PPARδ. The marked increase in ROS levels induced by Ang II was also eliminated by the inhibition of phosphatidylinositol 3-kinase (PI3K) but not of protein kinase C, suggesting the involvement of the PI3K/Akt signalling pathway in this process. Accordingly, ablation of Akt with siRNA further enhanced the inhibitory effects of GW501516 in Ang II-induced superoxide production. Ligand-activated PPARδ also blocked Ang II-induced translocation of Rac1 to the cell membrane, inhibiting the activation of NADPH oxidases and consequently ROS generation. These results indicate that ligand-activated PPARδ plays an important role in the cellular response to oxidative stress by decreasing ROS generated by Ang II in vascular cells.</P>
