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.

$Che{\breve{o}}n$ (提堰) refers to the irrigation facilities used to provide water to the land on which rice is farmed. As the maintenance of $Che{\breve{o}}n$ required great amounts of capital, labor, and technology, the construction and maintenance of such facilities was controlled by the government. $Che{\breve{o}}n$ was perceived as being of particular importance during the $Che{\breve{o}}n$ era, which adopted agriculture as the basis of state management. Therefore, the management of $Che{\breve{o}}n$ was considered to be one of the main state policies. This is why $Che{\breve{o}}n$-related records can often be found in the historical documents written during the $Che{\breve{o}}n$ era. As such historical documents in the form of Jiriji (地理誌, geographical descriptions) include detailed descriptions of the number, size, and location of $Che{\breve{o}}n$ in individual counties($kunby{\breve{o}}n$), these help to conduct comprehensive analysis of the state of $Che{\breve{o}}n$ during the $Che{\breve{o}}n$ era. Based on these facts, this study attempts to establish a database of the $Che{\breve{o}}n$-related contents included in the <$Y{\breve{o}}jitos{\breve{o}}$(與地圖書)> published during the latter period of $Che{\breve{o}}n$, and using the established database, to identify the regional characteristics of $Che{\breve{o}}n$. More precisely, by analyzing the state of the distribution of $Che{\breve{o}}n$ at the national level, an effort was made to review the regional characteristics of $Che{\breve{o}}n$ in terms of their distribution and of the natural geographical conditions found in the locales where $Che{\breve{o}}n$ were located, as well as of the interrelation between such $Che{\breve{o}}n$ and socioeconomic factors such as the scale of the population and the size of the area under cultivation. Other factors which were delved into included matters related to the size of $Che{\breve{o}}n$ such as their perimeter, length, and scale of the area which they irrigated, the characteristics of the locales where $Che{\breve{o}}n$ were located, and the regional differences in the characteristics of $Che{\breve{o}}n$.

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.

In the previous study(6), we constructed the CheY-OmpR hybrid, Chp, which affects the expressions of ompF and om pC genes. Here we further characterize these effects and present the regulatory mechanism based on in vivo and in vitro data. Although Chp retained the sequence-specific DNA-binding ability, it was not possible to enhance transcriptional activity, suggesting that it may act as a competitive inhibitor to OmpR. The DNA-binding affinity of Chp was not modulated by phosphorylation of its Che Y portion. Chp was able to increase ompR transcription. FurthemlOre, it was found that the wild-type OmpR also exerts the same effect, which is also eOlltrolled by changes in medium osmolarity and in EnvZ activity.
