가족 정책의 차이에 따른 주관적 건강 궤적의 성별 격차: 덴마크, 독일, 한국 중년을 중심으로
김민혜 ( Kim¸ Minhye ),강영호 ( Khang¸ Young-ho ) 한국보건사회연구원 2020 保健社會硏究 Vol.40 No.4
본 연구에서는 주관적 건강(self-rated health)의 잠재성장곡선(latent growth curves) 분석 방법을 활용하여 한국 중년 남성과 여성의 건강의 성별차 및 건강에 영향을 미치는 요인에서의 차이를 덴마크, 독일과 비교하여 비교사회학적인 통찰을 얻고자 한다. 덴마크는 젠더 정책의 맞벌이 모형을, 독일은 가족 중심 모형의 대표 국가 중 하나이다. 한국은 잔여적인 지지 모형에서 맞벌이 모형으로의 변화가 시작되는 시점에 있다고 할 수 있다. 덴마크와 독일 자료로는 유럽 건강・노화・은퇴조사의 2007년부터 2015년까지, 한국은 고령화연구패널조사의 2006년부터 2014년까지의 5개 차수가 사용되었다. 50세-64세의 중년 남성과 여성이 분석 대상이었다(덴마크 총 1,403명, 독일 총 1,245명, 한국 총 4,301명). 비제약 모형에서 한국 남성의 건강 궤적이 여성보다 양호하여 성별격차를 보였다. 덴마크의 경우 남성과 여성의 차이가 거의 없고, 독일의 경우 여성이 남성보다 약간 양호한 궤적을 보였다. 제약 모형에서 한국 여성은 덴마크, 독일과 다르게 남성에 비해 교육 수준이 낮은 경우의 건강상의 불리함이 크고, 덴마크와 다르게 남성에 비해 노동지위가 있을 경우의 건강상의 혜택이 적었다. 또한 덴마크, 독일과 비슷하게 남성에 비해 가구 소득이 높을 경우의 건강상의 긍정적 효과가 두드러지지 않았다. 한국 남성의 경우 덴마크, 독일과 다르게 여성에 비해 단순반복직일 경우의 건강상의 부정적 효과가 컸다. This study compares the gendered inequalities of longitudinal change of health (self-rated health, SRH) and the effects of socioeconomic status among the middle-aged men and women. Countries with greater (Denmark, dual-earner support), medium (Germany, general family support), and lower (South Korea, residual support) levels of support system for women were selected. The Survey of Health, Aging and Retirement in Europe (2007-2015) and the Korean Longitudinal Study of Ageing (2006-2014) were used (total 1,403 Danes, 1,245 Germans, and 4,301 Koreans). Multiple group latent growth curve models were employed. Unconditional models showed that Korean men had better health trajectories than their female counterparts. No gender difference was found among Danes and women was slightly better among Germans. Conditional models yielded that, unlike Denmark and Germany, Korean women were more disadvantaged in terms of lower education than Korean men. Unlike Denmark, Korean women with working status gained less benefit than Korean men. In addition, similar to Denmark and Germany, Korean women with more household income did not experience much increase in SRH than Korean men. Unlike Denmark and Germany, Korean men with routine jobs were more disadvantaged than Korean women.
Statistical Mechanics of One-Dimensional Charged Hard-Rod Systems
Minhye Heo,장새내,신기량,김순철 한국물리학회 2019 새물리 Vol.69 No.10
A one-dimensional Coulomb system, in which two charged colloids are neutralized by a collection of hard-rod counterions, was studied using isobaric and canonical ensembles. The exact isobaric and canonical partition functions were obtained. The explicit closed forms for the canonical particle density and the thermodynamic variables were obtained. The one-dimensional charged hard-rod system does not exhibit a phase transition. The charged hard-rod system also shows an attraction between like-charge particle, as well as the point-charged system [Phys. Rev. E 92, 042134 (2015)], even though the strong hard-core repulsion between two counterions enhances the screening effect between like charges.
The Safety Standards and ASIC Development for the Electronics Stability Control System
Minhye Yu,Kwan Seek Kim 한국자동차공학회 2010 한국자동차공학회 학술대회 및 전시회 Vol.2010 No.11
Functional safety is a key paradigm of next-generation electronic vehicle systems. ‘SIL3 capable micro-controllers’ are about to production. Continental received the SIL3 certification for a chipset, as the first company in the automotive industry in 2009. However, safety standards like IEC61508 and ISO26262 certify not only MCU, but the whole ECU system. In order to attain requirements to attain SIL3 certification, the hardware and software trade-offs are necessary. This paper intends to explain double ECU concepts for the safety standard. ASIC design will approach on IEC-61508 functional safety standard by multiple concepts. ESC system can satisfy SIL3 and at the same time, be evolved into the smarter and safer one.
Application of body composition zones in boys with nonalcoholic fatty liver disease

Purpose: Screening nonalcoholic fatty liver disease (NAFLD) by body mass index (BMI) as a single surrogate measure for obesity has limitations. We suggest considering body composition zones by drawing a body composition chart composed of body composition indices, including BMI and percent body fat (PBF), to visualize the risk of NAFLD in obese children and adolescents. Methods: Thirty-eight boys diagnosed with NAFLD were selected retrospectively from patients who visited Konkuk University Medical Center from 2006 to 2015. They had gone through body composition analysis by bioelectrical impedance analysis (BIA), and biochemical analyses, including a liver function test (LFT) and lipid panel, were performed. Fat-free mass index (FFMI) and fat mass index (FMI) were calculated from body composition analysis and height. We plotted FFMI and FMI of patients on a body composition chart and classified the patients into zones A to D. In addition, we analyzed the correlations between LFT, lipid panel, and body composition indices. Results: Thirty-three of 38 boys (86.8%) were located in zone C, corresponding to high BMI and PBF. Four boys (10.5%) were located in zone D, which correlates with sarcopenic obesity. One boy located in zone B was a muscular adolescent. Alanine aminotransferase level was positively correlated with PBF, FMI, and BMI z-score. Conclusion: Body composition zones on a body composition chart might be useful in risk assessment in obesity-related diseases such as NAFLD. Zones on a body composition chart could have practical applications, especially in sarcopenic obese children and adolescents.
