Graduate School of Public Health, Seoul National University The national health insurance system in Korea is characterized as relatively high out-of-pocket payments, which are the principal source of catastrophic health expenditure (CHE). The objectives of this study are to estimate the incidence of household CHE and to clarify the characteristics that affect the occurrence and recurrence of household CHE using the Seoul Welfare Panel Survey database for 2008 and 2010. Thresholds to estimate CHE were 10% and 20% of the total household income (T/X), and 25% and 40% of the income excluding food share (T/Y). Determinants of the occurrence and recurrence of CHE at the threshold of T/X=10% were analysed using multiple logistic regression models. Out of the 3,665 households that responded in 2008 survey, households with CHE were 12.07% (T/X${\geq}$10%), 5.34% (T/X${\geq}$20%), 6.84% (T/Y${\geq}$25%), and 4.44% (T/Y${\geq}$40%). Risk factors associated with household CHE included living with a spouse, non-Medicaid beneficiary, householder unemployment, low household income, the number of disabled members, poor subjective health, and the number of chronic diseases. A total of 41.78% of households with CHE in 2008 repeatedly experienced CHE in 2010. Risk factors of CHE recurrence included decreased household income and an increase in chronic diseases over the two time periods, the number of members with disability or chronic diseases, and the presence of cancer patients in 2008. Households with lower socioeconomic and health status had a higher financial burden on health care than do their counterpart households. There is a need to enhance society-wide financial protection from health spending among vulnerable citizens in Seoul, particularly, households with low income, disabled members or cancer patients.

Objectives: Describe out-of-pocket payment (OOP) and the proportion of Peruvian households with catastrophic health expenditure (CHE) and evaluate changes in socioeconomic inequalities in CHE between 2008 and 2017. Methods: We used data from the 2008 and 2017 National Household Surveys on Living and Poverty Conditions (ENAHO in Spanish), which are based on probabilistic stratified, multistage and independent sampling of areas. OOP was converted into constant dollars of 2017. A household with CHE was assumed when the proportion between OOP and payment capacity was ≥0.40. OOP was described by median and interquartile range while CHE was described by weighted proportions and 95% confidence intervals (CIs). To estimate the socioeconomic inequality in CHE we computed the Erreygers concentration index. Results: The median OOP reduced from 205.8 US dollars to 158.7 US dollars between 2008 and 2017. The proportion of CHE decreased from 4.9% (95% CI, 4.5 to 5.2) in 2008 to 3.7% (95% CI, 3.4 to 4.0) in 2017. Comparison of socioeconomic inequality of CHE showed no differences between 2008 and 2017, except for rural households in which CHE was less concentrated in richer households (p<0.05) and in households located on the rest of the coast, showing an increase in the concentration of CHE in richer households (p<0.05). Conclusions: Although OOP and CHE reduced between 2008 and 2017, there is still socioeconomic inequality in the burden of CHE across different subpopulations. To reverse this situation, access to health resources and health services should be promoted and guaranteed to all populations.

농경사회였던 조선시대에는 수리시설의 축조와 관리가 국가의 중대한 관심사였다. 제언은 축조와 관리에 많은 비용과 노동력, 그리고 기술이 투입되었고, 따라서 제언의 건설 및 유지 관리는 보통 국가가 담당하였다. 이 때문에 조선시대의 문헌에는 제언에 대한 기록이 적지 않게 등장한다. 이중에서도 지리지(地理誌)는 당시 각 군현의 제언의 숫자, 규모, 위치 등이 기재되어 있어 조선시대 제언의 상황을 가장 종합적으로 파악할 수 있게 해준다. 본 연구는 이러한 점에 착안해, 조선후기 간행된 "여지도서(與地圖書)"에 수록되어 있는 제언 관련 내용을 데이터베이스화하고, 이를 이용하여 제언의 지역적 특성을 규명하는 데 목적이 있다. 구체적으로 먼저 제언의 명칭, 관리, 수축 경위 등과 함께 규모의 지역적 특성을 전반적으로 살펴보았다. 그리고 제언의 전국적인 분포상황을 분석하여 그것이 기후 지형 등 자연조건, 그리고 인구규모, 경지면적, 농법 등과 어떤 관련성이 있는지 고찰하였다. 그 결과, 제언은 각 지역의 자연환경은 물론 사회경제적 조건, 문화적 조건까지 반영하고 있는 것으로 나타나, 제언의 특성에 대한 고찰은 궁극적으로 조선후기 각 지역의 지역성 파악의 실마리가 될 것으로 기대된다.

1. Objectives The pesent study purposed to examine Dongmu Lee Je-Ma's Sasang philosophy from the viewpoint of Che-Yong relation and to understand the effect of Che-Yong relation on Dongmu philosophy. 2. Methods First, we briefly compared the concept of Che-Yong relation in Jeongju philosophy, which has a dualistic philosophical structure, with the concept of Han Suk-Ji's harmonious Che-Yong relation, which has a monistic philosophical struaure and, based on rhe result, analyzed the characteristics of rhe concept of Che-Yong in Dongmu philosophy focused on Seongmyeong rheory, Sadan rheory and Hwakchung theory in ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$. 3 Results and Conclusions Jeongju philosophy is different from Dongmu philosophy in irs philosophical struaure characterized by Che-Yong relation, and the concept of Che-Yong in Dongmu philosophy forms the characteristics of Han Suk-ji's monistic harmonious Ole- Y ong relation. This produces results as follows. (1) Form a universal view of human beings centering of man's autonomous will and possibility. (2) Have a philosophical structure understood nor as a partial thought but as a total thought. (3) Assert that man has a good nature fundamentally and is obliged to practice goodness. (4) Assume that all human beings are equal. (5) It is assumed that the structural characteristics of harmonious Che-Yong relation in Dongmu philosophy can be the ground of definition of Silhak (practical science) in Oriental philosophy. It can be said that the realities of the universe and human beings can be discussed in philosophical structure with the logic of harmonious Che-Yong relation based on the unity of time and space. The philosophical logic based on the tealities can be defined as Silhak.

Traditional foods of Che Ju Do, an island located on south sea of Korean peninsula, were composed of moutaineous and coastal food. According to the review of historical records and evidences, ancestors of Che Ju Do island had consumed starchy root or marine food such as arrow root, bracken root, kelp, crab and so on. There are more than 500 kinds of traditional foods in Che Ju island, but most of them were poorly processed or cooked compared to that of the continent of the peninsula.

Background: The objective of this study was to examine the effect of occurrence and reoccurrence of catastrophic health expenditure (CHE) on transition to poverty and persistence of poverty in South Korea. Methods: The data of the year 2008-2011 from the Korea Health Panel were used. CHE was defined as the share of total health expenditure in a household out of a household's total income at various threshold levels (more than 5%, 10%, 15%, and 20%). The effect of catastrophic expenditure on transition to poverty and persistence of poverty was analyzed through multivariate logistic regression. Results: The shares of households facing CHE at various threshold levels have increased gradually with 37.7%, 21%, 13.1%, and 9.5% in 2011. Households facing CHE were more likely to experience transition to poverty at thresholds level of more than 5% and 20% in 2010 set. Households facing CHE seemed to experience persistence of poverty, but it was not statistically significant. About 40% of households facing CHE in 2009 encountered another shock of CHE in 2010. Households without CHE seemed to experience more transition to poverty and persistence of poverty, but it was not statistically significant. For household with multiple CHE, those with medical aid were more likely to experience transition to poverty with statistical significance, but the statistical significance disappeared in case of persistence of poverty. Conclusion: The Korean health system needs to be improved to serve as a social security net for addressing transition to poverty and persistence of poverty due to facing CHE.

In this report, the physical and chemical properties of Che-ju aggregates were stedued, and the properties of concrete using 5 types combinations of Che-ju aggreagtes were compared with those of concrete using Dag-jeon area aggreagtes. As a result of the properties of Che-ju aggregates are very different with Dae-jeon area aggregates in many aspects. Especially, entrained air content of aggregate is over 1.5% so that the freezing & thawing resistance of concrete was caused in decrease. And the texture properties of Che-ju aggregates and a little content of the entrained air in mortar increase bonding stress between mortar and aggregate, as a result in improving the compressive strength of concrete. Meanwhile, the relationship between cement water ratio(C/W) and 28days compressive strength of concrete(F28) is derived from the stastical regression using experimental data as $F_{28} = -99 + 276 *($(C/W), so this eqation is useful for mix-design of concrete in Che-ju area.

Purpose: To investigate whether changes in Medical Aid (MA) status are associated with unmet need and catastrophic health expenditure (CHE). Methods: Data from the 2010 to 2014 Korea Health Panel (KHP) were used. The impact of changes in annual MA status ('MA to MA,' 'MA to MA Exit,' 'MA Exit to MA,' and 'MA Exit to MA Exit') on unmet need (all-cause and financial) and CHE (10% and 40% of household capacity to pay) were examined using the generalized estimating equation (GEE) model. Analysis was conducted separately for MA type I and II individuals. Results: In 1,164 Medical Aid type I individuals, compared to the 'MA to MA' group, the 'MA to MA Exit' group had increased likelihoods of all-cause and financial unmet need. This group also showed higher likelihoods of CHE at the 10% standard. The 'MA Exit to MA Exit' group showed increased likelihoods at the 10% and 40% CHE standards. In 852 type II recipients, the 'MA to MA Exit' group had higher likelihoods of CHE at the 10% standard. Conclusions: Type 1 MA exit beneficiaries had higher likelihoods of all-cause and financial unmet need, along CHE at the 10% standard. Type I 'MA Exit to MA Exit' beneficiaries also showed higher likelihoods of CHE at the 10% and 40% standards. In type II recipients, MA exit beneficiaries had higher likelihoods of CHE at the 10% standard. The results infer the importance of monitoring MA exit beneficiaries as they may be vulnerable to unmet need and CHE.

이전의 연구에서 우리는 CheY-OmpR 융합단백질인 'Chp'을 제조하여 ompF와 ompC 유전자에 미치는 영향을 조사하였다(6). 본 연구에서는 Chp의 활성 및 작용기작을 in vivo와 in vitro 실험을 통해 알아보았다. 융합단백질 Chp은 OmpR과 마찬가지로 DNA에 염기서열 특이적인 결합을 하지만, 유전자의 전사 활성 기능은 나타내지 않았다. 따라서 Chp의 ompF/C 유전자의 발현에 대한 효과는 DNA 결합 부위에 대한 OmpR과의 경쟁에 의해 나타나는 것으로 결론지을 수 있다. 그러나, in vivo와 in vitro 실험에서 Chp의 인산화에 따른 DNA 결합력 변화는 관찰할 수 없었다. Chp이 ompR 유전자의 발현을 증가시키는 것이 관찰되었는데, OmpR도 이와 같은 효과를 나타내었으며, 배지의 삼투압을 변화시켰을 때와 EnvZ 돌연변이체에서도 ompR 유전자의 발현변화가 관찰되었다.
