최슬기,최재원,양민호 한국분말재료학회 2023 한국분말재료학회지 (KPMI) Vol.30 No.2

Li1.3Al0.3Ti1.7(PO4)3(LATP) is considered a promising material for all-solid-state lithium batteries owing to its high moisture stability, wide potential window (~6 V), and relatively high ion conductivity (10-3–10-4 S/cm). Solid electrolytes based on LATP are manufactured via sintering, using LATP powder as the starting material. The properties of the starting materials depend on the synthesis conditions, which affect the microstructure and ionic conductivity of the solid electrolytes. In this study, we synthesize the LATP powder using sol-gel and co-precipitation methods and characterize the physical properties of powder, such as size, shape, and crystallinity. In addition, we have prepared a disc-shaped LATP solid electrolyte using LATP powder as the starting material. In addition, X-ray diffraction, scanning electron microscopy, and electrochemical impedance spectroscopic measurements are conducted to analyze the grain size, microstructures, and ion conduction properties. These results indicate that the synthesis conditions of the powder are a crucial factor in creating microstructures and affecting the conduction properties of lithium ions in solid electrolytes.

사회통합 역량으로 바라본 터키 사회의 질

최슬기 서울대학교 국제학연구소 2013 국제지역연구 Vol.22 No.2

According to the World Bank, the GDP per capita in Turkey in 2011 is $10,524 whereas it is $22,424 in South Korea. Does this mean that the social quality of Turkey is roughly half of South Korea’s? This paper tries to show that we may need to look into not only economic facts but also social facts in order to evaluate the social quality. Using a comparative sociological perspective, four domains related with social cohesion were analyzed. Specifically, they are trust, network, integrated norms/values, and identity. The main data is Life and Society Survey, conducted in Turkey and South Korea in 2012. The results show that Turks have higher social cohesion compared to South Korean. Turks are more likely to trust outgroups and institutions. They have more contacts with families, neighbors, and friends. They are especially active in charity work and community volunteering. Their opinions on welfare were relatively in the same direction to welfare extension regardless of generation and class. They are very proud of their country. These results originate from Islamic traditional culture. A good example is the Hizmet movement. It shows that social integration in Turkey society is stronger than it is in South Korea. 2011년 기준 터키의 일인당 국민소득은 10,524불로 한국의 22,424불에 비교하여 절반 정도의 크기이다. 그렇다면 터키의 사회의 질도 대략 한국의 절반 수준이라고 말할 수 있을까? 이 글은 경제적 측면뿐 아니라 사회적 측면에서도 사회의 질을 평가하는 것이 필요하다는 것을 보여주고자 한다. 이를 위하여 이 논문은 비교사회학적 시각에서 터키 사회를 한국 사회와 비교 분석해보았다. 구체적으로 한 사회의 유지 발전 능력을 의미하는 사회응집성을 신뢰, 공동체 참여, 통합된 규범 내지 가치, 정체성이라는 네가지 영역으로 나누어 살펴보였다. 분석자료로는 2012년도에 한국과 터키에서 동시에 실시된 '삶과 사회에 관한 조사'를 활용하였다. 분석결과, 터키의 사회응집성은 한국보다 더 높게 나타났다. 터키인들은 외집단과 기관에 대한 신뢰도가 한국인보다 높았다. 터키인들의 가족, 친구, 이웃과 접촉빈도도 더 높았고, 정치적 모임이나 시민단체 같은 공공의 성격을 갖는 모임에 참여빈도도 더 높았다. 특히 봉사나 자선활동에 참여도가 한국보다 훨씬 활발했다. 통합된 규범/가치 차원에서도 터키인들은 복지증대와 이를 위한 증세, 보편복지에 대한 지향이 다수를 차지하였다. 연령 계층별 의견차이도 크지 않았다. 마지막으로 정체성 측면에서도 소속감, 국가 자긍심 두 영역 모두에서 터키가 한국보다 강하게 나타나고 있는 것이 확인되었다. 이러한 결과는 경제적 소득수준으로는 파악되지 않았던 사회적 측면에서 터키 사회의 질이 발달되어 있음을 보여준다. 히즈멧운동의 사례에서 나타나듯이 이슬람 전통사회가 갖고 있는 상호 부조 문화의 힘이라고 해석될 수 있다.

TRPV1 in Salivary Gland Epithelial Cells Is Not Involved in Salivary Secretion via Transcellular Pathwa

최슬기,신용환,남궁은,황성민,Xin Cong,Guangyan Yu,박경표 대한약리학회 2014 The Korean Journal of Physiology & Pharmacology Vol.18 No.6

Transient receptor potential vanilloid subtype 1 (TRPV1) was originally found in sensory neurons. Recently, it has been reported that TRPV1 is expressed in salivary gland epithelial cells (SGEC). However, the physiological role of TRPV1 in salivary secretion remains to be elucidated. We foundthat TRPV1 is expressed in mouse and human submandibular glands (SMG) and HSG cells, originatedfrom human submandibular gland ducts at both mRNA and protein levels. However, capsaicin (CAP),TRPV1 agonist, had little effect on intracellular free calcium concentration ([Ca2+]i) in these cells,although carbachol consistently increased [Ca2+]i. Exposure of cells to high temperature (>43oC) oracidic bath solution (pH5.4) did not increase [Ca2+]i, either. We further examined the role of TRPV1in salivary secretion using TRPV1 knock-out mice. There was no significant difference in the pilocarpine(PILO)-induced salivary flow rate between wild-type and TRPV1 knock-out mice. Saliva flow rate alsoshowed insignificant change in the mice treated with PILO plus CAP compared with that in micetreated with PILO alone. Taken together, our results suggest that although TRPV1 is expressed inSGEC, it appears not to play any direct roles in saliva secretion via transcellular pathway.

국민건강보험 재정전망의 품질통제 개선방안에 관한 연구: 미국 메디케어 및 한국 국민연금과의 사례비교

최슬기 한국행정학회 2022 韓國行政學報 Vol.56 No.4

This study compared the quality control of the financial forecast of Korea’s National Health Insurance (NHI) with US Medicare and Korea’s National Pension Service (NPS). Comparative analysis showed that, first, NHI differed from Medicare and NPS in its transparency in that it presented only the forecast results and did not disclose any information on the process by which the results were derived. Second, in relation to validation, while NHI mainly relied on the internal developer test, Medicare detected and corrected errors in the forecast model by the overlapped validation system inside and outside of forecast governance. Korea’s National Pension Service is similar in that it mainly relies on the internal developer test for validation, but it differs in that the subject of the developer test is a special committee composed of external experts, and the process and results are disclosed. 본 연구는 국가재정법과 국민건강보험법에 따른 국민건강보험 재정전망에 대한 품질통제를미국 메디케어 및 한국 국민연금의 재정전망 사례와 비교분석하였다. 주요 분석결과로는 첫째, 건강보험 재정전망은 전망결과만을 공개할 뿐, 전망모형 및 방법론 등 전망결과의 도출과정에관한 정보를 전혀 공개하고 있지 않다는 점에서 투명성에 기반한 메디케어 및 국민연금 사례와큰 차이를 보였다. 둘째, 국민건강보험 재정전망이 내부 전문가에 의한 검토에만 타당성 검증을주로 의존한 반면, 국민연금은 내부검토를 민간위원회에서 주도하고 그 내용을 외부에 공개하고 있었으며, 메디케어의 경우 내외부의 중첩적인 타당성 검증체계를 통해 모형의 오류를 발견하고 모형의 지속적인 보완・개선을 도모하였다. 본 연구는 시사점으로서 재정전망 과정의 투명성과 타당성 검증체계라는 두 가지 차원에서 품질통제의 개선을 통해 재정전망의 결과가 합리적 보험정책 결정과 향후 제도개혁을 위한 지적 근거로 활용될 수 있어야 한다는 점을 강조하고있다.

Motherhood and Wage Discrimination, Evidences from NLSY 1982-2006, United States

최슬기 한국사회학회 2011 韓國社會學 Vol.45 No.3

This article explores the wage gap between mothers and non-mothers, which is called the motherhood wage penalty. Previous researches have focused on the loss of job experience due to motherhood as a key reason of the penalty. On the contrary, this paper focuses on discrimination against motherhood. Using data from the 1982-2006 National Longitudinal Study of Youth with residual analysis, I find that women are experiencing 2% of motherhood wage discrimination per child. It is roughly one-third of the gross motherhood wage penalty. I also find that sizes of the discrimination are different by the location in the occupational hierarchy. Managers/professionals are not suffering from wage discrimination. Whereas, manual workers are suffering from the discrimination, 3% per child. The 69% of the wage gap persists after controlling for productivity measures. Even among laborers and service workers, their penalties are 6% per child and more than 90% of wage gap is attributed to discriminatory factors. It implies that motherhood discrimination persists in spite of the declined gender wage discrimination, especially mothers who does not have authorities nor skills. The discrimination may just be modified or happen at a different boundary, from women vs. men, to mothers vs. non-mothers.

Women’s Wage and Childbearing

최슬기 한국인구학회 2012 한국인구학 Vol.35 No.2

This research studies how women’s hourly wages affect childbearing using data from the National Longitudinal Survey of Youth. The results of discrete time hazard model show that the relationship between women’s hourly wage and fertility is dynamic. Overall relationship looks negative, but they are not consistent across education levels. Women who have a high school diploma or less have a tendency to decrease childbearing when their wages increase. But women who have some college experience or a college degree are likely to have children when their wages increase. It means that only for highly educated women who are likely to be in high paying decent jobs, the rise of income can be used as a resource for reconciling the mother’s and worker’s roles. Or, for less educated women who are likely to be in the low paying jobs, the rise of income is not large enough to lessen role incompatibility.

최슬기,박영애 한국무용예술학회 2018 무용예술학연구 Vol.69 No.2

The purpose of this study is to propose a Gospel-centered integrated educational program for children. With the features of child development as well as character, creativity, and aspects of physical expression, a patchwork ESA teaching model was selected to design an integrated arts program that included dance/movement, music, art, and play. The age of children, the number of participants in class, the classroom environment, and etcetera were also taken into consideration. The program was implemented with each session in 50 minute segments and detailed plans set twice a week for a total of 12 sessions. This Gospel-centered integrated arts program for children increased their interest and participation. I suggest that is was effective for drawing out creative expression through education and dance/movement. Ultimately this can be seen as an educational program that promotes the holistic growth of children.

최슬기,장주영,김규웅,박상민,이기헌 대한암학회 2018 Cancer Research and Treatment Vol.50 No.4

Purpose The purpose of this study was to investigate the effect of smoking habit change on the risk of cancer. Materials and Methods From the Korean National Health Insurance Service database, we determined the change in smoking habit between the first (2002 and 2003) and second (2004 and 2005) health examination periods. A total of 143,071 men were categorized into baseline heavy ( 20 cigarettes per day), moderate (10-19 cigarettes per day), light (< 10 cigarettes per day) smokers, quitters, and never smokers, after which the change in smoking status was determined during the second health examination. The participants were then followed up from 2006 to 2013 for all cancer, smoking related cancer, and lung cancer. Results Compared to heavy continual smokers, heavy smokers who quit had reduced risk of smoking related cancer (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.56 to 0.97) and tended to have reduced risk of all cancer (HR, 0.87; 95% CI, 0.75 to 1.00). Moderate smokers who reduced the amount of smoking to light levels had decreased risk of all cancer (HR, 0.82; 95% CI, 0.72 to 0.94), smoking related cancer (HR, 0.74; 95% CI, 0.59 to 0.93), and lung cancer (HR, 0.55; 95% CI, 0.38 to 0.79) compared to heavy continual smokers. Conclusion Smoking reduction decreases the risk of all cancer, smoking related cancer, and lung cancer. While smoking cessation should be the treatment of choice for smokers, smoking reduction may serve as an alternative strategy for those who cannot quit.
