박은주 ( Park¸ Eunjoo ) 한국사회보장학회 2021 사회보장연구 Vol.37 No.3

본 연구는 일시적 노동능력상실에 대한 소득보장제도인 산재보험 휴업급여와 상병수당 제도를 OECD 국가를 중심으로 비교 분석하였다. 여기서는 제도형태, 적용대상, 급여 수준, 대기기간, 지급기간 등을 중심으로 두 제도를 비교 분석하였다. 제도형태에 있어서는 두 제도 모두 사회보험으로 운영하는 것이 일반적이었으며, 적용대상에 있어서는 근로자의 경우 적용범위가 거의 유사하나 자영업자의 경우 적용여부가 매우 다양하게 나타나고 있었다. 급여수준에 있어서는 휴업급여가 상병수당보다 더 높게 나타나는 것이 일반적이었으며, 대기기간에 있어서는 상병수당은 대기기간을 두는 것이 일반적이나 휴업 급여는 대기기간을 두지 않는 국가가 많은 편이었다. 그리고 지급기간에 있어서는 상병 수당은 대부분의 국가에서 제한을 두는 것으로 나타나지만, 휴업급여는 제한을 두는 국가와 두지 않는 국가가 유사하게 나타나고 있다. 이러한 분석결과를 바탕으로 우리나라 상병수당제도 도입에서의 시사점을 도출하였다. This study compares the temporary disability benefit of workers' compensation and sickness benefit, which are income guarantee systems for temporary incapacity for work, focusing on OECD countries. This study compares the two systems with a focus on the types of programs, coverage, benefit level, waiting period, and payment period. First, both systems are generally operated by social insurance system. Second, the coverage for workers is almost similar, but the coverage for the self-employed is very diverse in both systems. Third, sickness benefit mainly has a waiting period, and temporary disability benefit mainly does not have it. Fourth, payment period for sickness benefit is generally limited, but there are many cases in which temporary disability benefit has no limitation on payment period. Based on these analysis results, implications for the introduction of the sickness benefit in Korea are drawn.

The purpose of this study is to examine educational needs for mothers of premature infants and to develop educational multimedia for mothers of premature and high risk infants. This research was designed as a descriptive study. Data were collected for four months from April 2002 to July 2002. One hundred and one subjects in one general hospital in Seoul participated in the study. Measurement tools used in this study was educational needs scale developed by Cho. Kyoul Ja et at. It asks mothers to rate each item on a four-point Likert type scale. The collected data were analyzed using SPSS win 8.0. All variables were listed as frequency, mean, standard deviation and percentiles. The results were as follows : The educational needs of the mothers of primi pregnancy were higher than the mothers of multi pregnancy. The educational needs on management of diseases such as prevention of infection, symptoms of disease, mental development, attachment promotion, congenital metabolism test, management of convulsion, care of vomiting and fever were higher than general care of infants such as immunization, measurement of temperature, hiccough care, follow up care. From the results above, I developed the educational multimedia for premature and high risk infant care. I think it will help to increase understanding of parents and to reduce stress level of mothers of premature and high risk infants.

The Effect of Hair Beauty Shop Customers' Perception of General Risks and Beauty Shop Risks on Consumer Sentiment

Juyeun Park(Juyeun Park),Eunjoo Choi(Eunjoo Choi),Kihun Han(Kihun Han) J-INSTITUTE 2023 Protection Convergence Vol.8 No.1

Purpose: As the COVID-19 pandemic began, the concepts that have been used in Korean society are “With Corona” and “Post Corona.” In Korea, social distancing and mask wearing were mostly lifted, but the sense of crisis did not disappear. As consumer sentiment shrank, productivity decreased, and the entire industry was af-fected, the beauty industry (mainly face-to-face services) is also subject to many negative effects. Consumer sen-timent appears irrational and rationally regulates consumption habits. The general risk perception and beauty shop risk perception of COVID-19 were set as factors that affect consumer sentiment of hair beauty service con-sumers. This study aims to provide basic data to present a differentiated strategy that is different from other service fields for the development of the beauty industry. Method: The data of this study were statistically analyzed using SPSS 25.0, and first, an exploratory factor analysis was performed to analyze the validity of the measurement tool. Reliability was analyzed using Cronbach's alpha coefficient. Frequency analysis and descriptive statistical analysis were performed, and chi-square test and multiple regression analysis were performed. Results: Social and environmental risk and economic risk, sub-factors of general risk perception, appeared to have a significant positive (+) effect on consumer sentiment, and human risk, a sub-factor of beauty shop risk perception, had a significant negative (-) effect on consumer sentiment. Was found to have an effect on In other words, it can be said that the higher the social and environmental risk and economic risk, sub-factors of general risk perception, the higher consumer sentiment, and the higher the human risk, the sub-factor of beauty shop risk perception, the lower consumer sentiment. Economic risk (β=.290, p<.001), human risk (β=-.231, p<.01), and social and environmental risk (β=.118, p<.05) affects consumer sentiment in the order has been shown to affect. Conclusion: ‘Presence of regular beauty shops’, ‘Beauty shop selection criteria’, and ‘Reason for reduction in beauty expenditure and items after COVID-19’ according to the age and gender of research subjects differ. There-fore, different marketing methods should be sought for each generation or gender. Since the relationship be-tween risk perception and consumer sentiment has been revealed, it can be utilized to help recover and improve hair beauty shop business in the future.

Xylitol stimulates saliva secretion via muscarinic receptor signaling pathway

Eunjoo Park,Hee Sam Na,Sunghee Jeong,Jin Chung 대한구강생물학회 2019 International Journal of Oral Biology Vol.44 No.2

Xylitol is well-known to have an anti-caries effect by inhibiting the replication of cariogenic bacteria. In addition, xylitol enhances saliva secretion. However, the precise molecular mechanism of xylitol on saliva secretion is yet to be elucidated. Thus, in this study, we aimed to investigate the stimulatory effect of xylitol on saliva secretion and to further evaluate the involvement of xylitol in muscarinic type 3 receptor (M3R) signaling. For determining these effects, we measured the saliva flow rate following xylitol treatment in healthy individuals and patients with dry mouth. We further tested the effects of xylitol on M3R signaling in human salivary gland (HSG) cells using real-time quantitative reverse-transcriptase polymerase chain reaction, immunoblotting, and immunostaining. Xylitol candy significantly increased the salivary flow rate and intracellular calcium release in HSG cells via the M3R signaling pathway. In addition, the expressions of M3R and aquaporin 5 were induced by xylitol treatment. Lastly, we investigated the distribution of M3R and aquaporin 5 in HSG cells. Xylitol was found to activate M3R, thereby inducing increases in Ca 2+ concentration. Stimulation of the muscarinic receptor induced by xylitol activated the internalization of M3R and subsequent trafficking of aquaporin 5. Taken together, these findings suggest a molecular mechanism for secretory effects of xylitol on salivary epithelial cells.

Activation of NLRP3 and AIM2 Inflammasomes by <i>Porphyromonas gingivalis</i> Infection

Park, Eunjoo,Na, Hee Sam,Song, Yu-Ri,Shin, Seong Yeol,Kim, You-Me,Chung, Jin American Society for Microbiology 2014 Infection and immunity Vol.82 No.1

<P><I>Porphyromonas gingivalis</I>, a major periodontopathogen, is involved in the pathogenesis of periodontitis. Interleukin-1β (IL-1β), a proinflammatory cytokine, regulates innate immune responses and is critical for the host defense against bacterial infection. However, excessive IL-1β is linked to periodontal destruction. IL-1β synthesis, maturation, and secretion are tightly regulated by Toll-like receptor (TLR) signaling and inflammasome activation. We found much higher levels of inflammasome components in the gingival tissues from patients with chronic periodontitis than in those from healthy controls. To investigate the molecular mechanisms by which <I>P. gingivalis</I> infection causes IL-1β secretion, we examined the characteristics of <I>P. gingivalis</I>-induced signaling in differentiated THP-1 cells. We found that <I>P. gingivalis</I> induces IL-1β secretion and inflammatory cell death via caspase-1 activation. We also found that <I>P. gingivalis</I>-induced IL-1β secretion and pyroptic cell death required both NLRP3 and AIM2 inflammasome activation. The activation of the NLRP3 inflammasome was mediated by ATP release, the P2X<SUB>7</SUB> receptor, and lysosomal damage. In addition, we found that the priming signal via TLR2 and TLR4 activation precedes <I>P. gingivalis</I>-induced IL-1β release. Our study provides novel insight into the innate immune response against <I>P. gingivalis</I> infection which could potentially be used for the prevention and therapy of periodontitis.</P>

Effect of Chemical Stabilizers in Silver Nanoparticle Suspensions on Nanotoxicity

Eunjoo Bae,Hee-Jin Park,Junsu Park,윤제용,이종협,김영훈,최경희 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.2

Colloidal silver nanoparticles (AgNPs) have been commercialized as the typically stabilized form via the addition of a variety of surfactants or polymers. Herein, to examine the effects of stabilizing AgNPs in suspension, we modified the surface of bare AgNPs with four type of surfactants (NaDDBS, SDS, TW80, CTAB) and polymers (PVP, PAA, PAH, CMC). The modified AgNPs was applied to compare suspension stability and nanotoxicity test using Escherichia coli (E. coli) as a model organism. Modification of AgNPs surface using chemical stabilizer may be not related with molecular weight, but chemical structure such as ionic state and functional group of stabilizer. In this study, it is noteworthy that AgNPs modified with a cationic stabilizer (CTAB, PAH) were importantly toxic to E. coli, rather than anionic stabilizers (NaDDBS, SDS). Comparing similar anionic stabilizer, i.e., NaDDBS and SDS, the result showed that lipophilicity of chemical structure can affect on E. coli, because NaDDBS, which contains a lipophilic benzene ring, accelerated the cytotoxicity of AgNPs. Interestingly, none of the stabilizers tested, including biocompatible nonionic stabilizers (i.e.,TW80 and cellulose) caused a reduction in AgNP toxicity. This showed that toxicity of AgNPs cannot be reduced using stabilizers.

Eunjoo Park 한국초등영어교육학회 2018 초등영어교육 Vol.24 No.3

The 2015 revised national English curriculum emphasizes developing English communicative competence. This study investigates effective teaching methods to improve English speaking skills and lower foreign language anxiety. For this purpose, 95 Korean sixth grade students were divided into two groups. In the experimental group, 47 students were taught through collaborative learning strategies and sentence frames while in the control group 48 students had classes of textbook contents and activities based on the national curriculum. Sentence frames are one of the scaffolding tools for language learners, and they are employed to help the participants in the experimental group engage in key expression practice. For 13 weeks, the students had two 40 minute classes per week. To determine the effect of the method, pre and post-data were collected through the English Speaking Proficiency Test (ESPT) Junior Level 2 and the Foreign Language Classroom Anxiety Scale translated into Korean. Additionally, participants’ opinions about effectiveness of the method were collected after the post-test by using a questionnaire. The results indicate that collaborative interaction using sentence frames had a positive effect on developing students’ speaking ability while also lowering learning anxiety in the elementary classroom. Participants also found the method useful in their language learning process.

The germination of the buds in'Hongisul' grapes is poor and especially the high ratio of shoots where the flowers failed to emerge it was difficult to secure a sufficient amount of harvest. Thus in this study the necrosis and the periodical change in the buds were observed morphologically and also the cause of necrosis of the bud was investigated in order to understand what was causing the low germination and flowering. There was no change in the size of the bud after June and based upon external observation there wasn't any retrogression or withering. However based on a microscopic examination the ratio of whole bud and main bud necrosis of the'Hongisul' grapes continued to increase after August and specially the ratio of the main bud necrosis continued to increase up to October. As for the size of the buds on the shoots the buds located on the 1st-3rd nodes from the basal part were small whereas the buds located on the 4-10th nodes were comparatively larger in its size. The ratio of necrosis of the bud was the highest at the 1st and 2nd bud meaning that the buds located at the basal part of the shoot were defective compared to those located at the end of the shoot. It was also found that when the growth of the shoot is active and the shoot diameter is thick it hindered the development of the buds. Therefore it was judged that long pruning of'Hongisul' grapes would help the emergence of the flowers as you could use the buds that have comparatively developed better. '홍이슬' 포도는 눈의 발아가 불량하고 특히 꽃송이가 출현하지 않는 신초의 발생이 많아 충분한 양의 결실 확보가 어려운 문제점이 발생하고 있다. 따라서 본 연구에서는 신초의 발아 및 개화가 불량한 원인을 파악하고자 눈의 시기적 변화와 눈의 괴사를 형태적으로 관찰하고 괴사원인을 조사하였다. 6월 이후에는 눈의 크기에 큰 변화가 없었으며 이후 외형적으로 관찰했을 때에는 퇴화나 고사가 나타나지 않았다. 반면에 현미경 검경 결과'홍이슬' 포도의 눈 및 주아 괴사율은 8월 이후에 계속 증가하였으며 특히 주아 괴사율은 10월까지 계속 증가하였다. 신초 내 눈의 크기는 기부로부터 1-3번째 마디의 눈의 크기가 작았으며 4-10번째 마디의 눈의 크기는 상대적으로 큰 것으로 조사되었다. 1번째 눈과 2번째 눈에서 눈 괴사율이 가장 높게 발생하여 기부의 눈이 가지의 끝에 있는 눈에 비해 불량하였다. 또한 신초의 생육이 활발해 가지가 굵으면 눈의 발달이 저해되는 것으로 나타났다. 따라서'홍이슬' 포도는 장초전정을 실시하는 것이 상대적으로 발달이 양호한 눈을 이용할 수 있어 꽃송이 출현에 유리할 것으로 생각되었다.

박은주 ( Eunjoo Park ) 현대영미어문학회 2018 현대영미어문학회 춘계학술대회 발표논문집 Vol.2018 No.-

This study investigates effective ways to develop English speaking skills. For this purpose, 95 6th grade students were divided into two groups. 47 students in the experimental group were taught through collaborative interaction using sentence frames while 48 students in the control group had regular classes based on the national curriculum. The collaborative interaction experimental group practiced key expressions with their peers employing collaborative learning strategies. They also used sentence frames when they practiced the key expressions. For 13 weeks, the students had two 40 minute classes per week. To see the effect of the method, a mock test of the English Speaking Proficiency Test (ESPT) Junior Level 2 was administered and the data of pre- and post- were analyzed. The results of the study indicate that collaborative interaction using sentence frames had a positive effect on developing students’ speaking ability in terms of fluency and comprehension.
