Objectives : To compare the degree of achievement of Universal Health Coverage (UHC) among 39 developing countries in Africa and to investigate the correlation between health care financing and the UHC index. Methods : For data, 14 UHC indexes were used in 2015 supplied by the World Health Organization (WHO). In addition, this study used a 10% of threshold point corresponding to the catastrophic health expenditures and a 25% of threshold points as a health care financing index. Results : It was found that there were significant difference among Least Low Developed Countries (LLDCs), Other Low Income Countries (Other LICs), Lower Middle Income Countiies (LMICs), Upper Middle Income Countires (UMICs) to compare the average value by nation on the UHC index. This study showed that the UHC index of LLDCs was lowest, but the average value was higher as it moved towards LMICs and UMICs. In addition, it was found that there was an average value difference among the groups like LLDCs, Other LICs, LMICs and UMICs. As a result of comparison, it was found that the spending of household health expenditure increased as LLDCs moved towards UMICs when the burden of household health expenditure was 25%. Conclusions : This study aimed to compare the UHC indexes of African nations and to investigate the correlation between the degree of spending of total expenditure on health and burden of household health expenditure and UHC, and its effect.

Objectives: No systematic review has explored the challenges related to worldwide universal health coverage (UHC). This study reviewed challenges on the road to UHC. Methods: A systematic electronic search of all studies that identified the challenges of worldwide UHC was conducted, without any restrictions related to the publication date or language. A hand search and a bibliographic search were also conducted to identify which texts to include in this study. These sources and citations yielded a total of 2500 articles, only 26 of which met the inclusion criteria. Relevant data from these papers were extracted, summarized, grouped, and reported in tables. Results: Of the 26 included studies, 7 (27%) were reviews, 6 (23%) were reports, and 13 (50%) had another type of study design. The publication dates of the included studies ranged from 2011 to 2020. Nine studies (35%) were published in 2019. Using the World Health Organization conceptual model, data on all of the challenges related to UHC in terms of the 4 functions of health systems (stewardship, creating resource, financing, and delivering services) were extracted from the included studies and reported. Conclusions: This study provides a straightforward summary of previous studies that explored the challenges related to UHC and conducted an in-depth analysis of viable solutions.

The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized a Roundtable Discussion as part of the official program of the UICC World Cancer Congress 2014 in Melbourne, Australia. The theme for the Roundtable Discussion was "Looking Toward the Realization of Universal Health Care 'UHC' for Cancer in Asia" and it was held on December 5, 2014. The meeting was held based on the recognition that although each country may take a different path towards the realization of UHC, one point that is common to all is that cancer is projected to be the most difficult disease to address under the goals of UHC and that there is, therefore, an urgent and pressing need to come to a common understanding and awareness with regard to UHC concepts that are a priority component of a post-MDG development agenda. The presenters and participants addressed the issue of UHC for cancer in Asia from their various perspectives in academia and international organizations. Discussions covered the challenges to UHC in Asia, collaborative approaches by international organizations, the need for uniform and relevant data, ways to create an Asia Cancer Barometer that could be applied to all countries in Asia. The session concluded with the recognition that research on UHC in Asia should continue to be used as a tool for cancer cooperation in Asia and that the achievement of UHC would require research and input not only from the medical community, but from a broad sector of society in a multidisciplinary approach. Discussions on this issue will continue towards the Asia-Pacific Cancer Conference in Indonesia in August 2015.

As the United Nations announced Sustainable Development Goals (SDGs) in 2015, the world changed its development goals from focusing on efficiency to equity. As a result, in the health sector, universal health coverage (UHC) has become one of the main issues. This paper reviews and discusses on future direction and issue of official development assistance program for developing countries. Korea International Cooperation Agency under the Ministry of Foreign Affairs published on Korea International Cooperation Agency's mid-term health strategy 2016-2020 developed on participation program with stakeholder including governments, civil society partner organizations, and educational institutions. The SDGs expands non-communicable diseases, UHC, and global health security from the existing Millenium Development Goals health sector. Progress toward UHC underpins the achievement of all other targets under SDG Goal 3. Progress in reducing health inequality across the life course is drawing on overall data and from specific target. In order to achieve SDG 3, a multi-disciplinary approach, convergence between IT and u-health of this development, is desirable.

A cylindrical constant volume combustion bomb is used to investigate the combustion characteristics and to analyze the heat quantity of homogeneous charge methane-air mixture under various initial pressures, excess air ratios and ignition times. As the overall pressure increase, the values of maximum combustion pressure, maximum heat release rate and cumulative heat release have been increased. But it is not very meaningful to compare with some values such as maximum combustion pressure, maximum heat release rate and cumulative heat release for different overall pressure due to the different heat energy of supplied fuel. So the each value is needed to be compared with normalized value, which is divided by the entered fuel energy. To analyze the heat quantity, some definitions including the CHR ratio, the UHC ratio and the HL ratio are needed and are calculated. As the overall pressure increase, the CHR ratios and the UHC ratios have been decreased, while the HL ratios have been increased. The CHR ratio of 300 ms has the higher value than that of 10000ms, and the HL ratios of 300 ms have a lower value.

A cylindrical constant volume combustion chamber was used to investigate the exhaust emission characteristics of homogeneous charge, stratified pattern and inhomogeneous charge under various conditions using gas chromatography. In the case of homogeneous charge condition, the $CO_2$ concentration is proportional to excess air ratio and overall charge pressure, the $CO_2$ concentration is proportional to excess air ratio and the UHC concentration is inversely proportional to ignition time and overall charge pressure. In the case of stratified pattern, the RI(rich injection) condition shows better exhaust emission characteristics, especially $CO_2$, than that of HI (homogeneous injection) or LI (lean injection) conditions. In inhomogeneous charge conditions, when initial charge pressure is increased, $CO_2$ and UHC concentration is reduced but $O_2$ concentration is increased. And when the excess air ratio of initial charge mixture is 3.0, UHC and $CO_2$concentration show lowest values.

This paper is the second part of several companion papers which compare the method of Air-fuel ratio(AFR) determination. In the previous paper, Eltinge chart was applied to the arbitrary fuel composition and the charts for gasoline, diesel, methanol, M85, liquefied petroleum gas(LPG), natural gas(NG), propane and butane were illustrated. In Eltinge chart, however, unburned hydrocarbon (UHC) is not used for determination of AFR. For improving accuracy, Eltinge suggested UHC compensation after the AFR reading in the chart. This compensation reduced the difference between real and reading value. In the compensation, however, the correction of oxygen and carbon dioxide is uncertain and there might be a mistake in conversion of UHC reading value. Therefore, the error is overestimated comparing with Spindt one which is most widely used. In addition, there is no comparison of the value with other useful methods. In this paper, the compensation of unburned HC was performed in Eltinge chart and the compensated value was compared with Spindts formula over wide range of AFR. The objects of investigating fuel are gasoline, methanol, NG and LPG. The result shows that Eltinge and Spindt method is flawlessly compatible and the difference between the two methods is under 0.3% in a λrange from 0.9 to 1.7. The method fur debugging instrumentation error is also presented.

This study focuses on the healthcare sector in Vietnam which is promoting universal health insurance for the achievement of Universal Health Coverage (UHC) under Sustainable Development Goals (SDGs). The purpose of this study is to examine the characteristics of the reform process of the health care system and the law on health insurance through the historical and cultural contexts and its implications from the perspective of development. Based on the three dimensions of UHC - extension of protection for population, provision of various medical services, and financial protection, the current status of the Vietnam healthcare sector is summarized respectively as follows. First, according to the revised Health Insurance law which came into effect in 2015, the mandatory health insurance premiums are calculated based on household units. Second, there is a medical network that can provide preventive and healthcare services centered on primary health care facilities, for example commune health stations (trạm y $t{\hat{e}}$ $X{\tilde{a}}$). Third, out-of-pocket expenditure is still a large proportion although public spending has increased and private spending has decreased since the enforcement of the health insurance law and various schemes. Vietnam is currently striving towards a universal health care system. The development of institutions and systems should be designed in a way that is appropriate for the members of the society rather than efficiency. This article findings shed light on the role of social values, family culture, and informal institutions.

A cylindrical constant volume combustion bomb is used to investigate the combustion characteristics and to analyzer the heat quantity of inhomogeneous charge methane-air mixture. To analyze the heat quantity, some definitions including the CHR ratio, the UHC ratio and the HL ratio are needed and are calculated. It is shown that the effect of stratification is not significant in case of the overall excess air ratio of 1.1, mainly due to the higher heat loss and lower thermal efficiency compared to those of homogeneous condition. In the case of the overall excess air ratio of 1.4, as the initial charge pressure decreases, the CHR ratio has been decreased while the HL ratio has been increased, Generally, as the initial charge pressure increases, the amount of injection mixture has been decreased and has resulted in lower mean velocity and turbulence intensity for injection mixture. Also, the injected mixture is too rich to result in mixing deficiency in combustion chamber. From these results, it could be possible to acquire the improvement of thermal efficiency and the reduction of heat loss simultaneously through the 2-stage injection in CNG direct injection engine.
