  • The objective of this study is to set urban ecosystem assessment indicators, assess the status of the urban ecosystems in 31 cities & counties in the capital region and based on which, to examine an improvement plan to resolve problems and raise quality and quantity of urban ecosystems. The study showed that the ecological base of 31 cities & counties was 48% on average, which indicates that their ecological property is the middle class. Their natural-ecological function was 63% and environmental-control function was 25%, showing that environment-control function was poor. Therefore, going forward, urban ecological base should be further improved. When securing an ecological base, creation techniques should be able to further enhance environmental-control function along with natural-ecological function. Also, additional effort should be made to conserve areas with high ecological value as much as possible and increase vegetation vitality by replacing tree species.

  • Some researcher started studies of natural capital from 1980's. But many researches are going along with the theme lately. Most assessment of ecosystem services are approaching a general assessment using a land-cover map. Therefore they have some problems such as overestimate, underestimate, and double counting, and so on. This study suggested a detailed typology for quantitative assessment about ecosystem services. It compared land-cover map and forest type map to select a based map and made criteria with reference to the literature and field survey. It subdivided a forest typology using ecological feature (natural forest, artifical forest), forest type (coniferous forest, mixed forest, hardwood forest) and age of stand in forest type map. Each forest type is widely distributed 21~40 ages of forests and biggest area is 21~40 ages of mixed forest in all forest typology. Further researches have to progress consistently assessment using detailed typology and function of forest ecosystem services.

  • The remittances play a major and a very critical role in promoting economic growth and development activities in the developing countries. In this study, the relationship between per capita gross domestic product (GDP) and remittances paid has been investigated based on the case studies in Malaysia from 1987 to 2018. Data was collected from various sources namely statistical yearbook by World Bank and Asian Development Bank. All variables are expressed in natural logarithm form. The technique utilized is the nonlinear autoregressive distributed lags (hereafter NARDL) approach which was introduced by Shin et al.(2014) to examine both short run and long run relationships, as well as the direction of causality, due to the asymmetric relationship between GDP and remittances. The bound test verifies asymmetric cointegration among the variables. The empirical results show that the remittances paid has a momentous short-run and long-run effect towards capital accumulation in Malaysia. Remittances also increase a positive relationship with capital accumulation for Malaysia. We found that remittances form a significant source of external capital and investment for developing countries especially Malaysia which helps in promoting economic development. Furthermore, as a developing country, foreign workers are a source of income to the receiving countries and an indicator to boost sender countries.

  • Background: Most studies of human papilloma virus (HPV) are aimed at the natural history of the infection and its relation to cancer; however, there are few studies to assess knowledge of the general population. Our aim was analyze the degree of knowledge of Argentinians about HPV infection and its prevention. Materials and Methods: We conducted a voluntary, anonymous and non-binding survey with 27 multiple-choice items, in twelve private and public establishments, selected to include a broad population in terms of education, age and gender. The survey consisted of three sections: individual characteristics of the volunteer, HPV infection basic knowledge, its prevention and the virus relationship with other cancers. Results: One thousand two hundred ninety seven volunteers aged 18 to 80 participated. The total number of correct answers was 45.1%. The correct answers for relationship HPV and cervical cancer was 62.1%. Almost 55% did not know about types of HPV that the vaccines for protection. Statistical analysis showed that women, single people, workers, the better educated, those who have had a STDs or HPV and receiving information through medical or educational establishments had greater knowledge of the topic. Only 0.2% of participants answered all questions correctly. Conclusions: Knowledge plays an important role in health care and the deficiency found in our population could influence the success of the measures taken in the fight against cervical cancer. In this regard, we believe it would be appropriate, not only to emphasize early diagnosis and vaccine implementation, but also incorporate new communication strategies, facilitating reception of accurate and precise information by all strata of society.

  • The research described in this report was conducted to find out how elements of the natural environment contributed to the formation of Chang'an, how its water system reinforced its status as the capital city, and what role it took for its urban function based on studies of the canal constructions. During the period of Sui and Tang, Chang'an built a sophisticated water system using Qu(渠), the irrigation facilities. In the water system, hills are called Yuan(原), and rivers with the proper environment to be developed plan into urban infrastructure facilities for irrigation water, urban living water, the composition of garden-based facility, reservoirs, and others. They improve agricultural productivity and, consequently, increase the city's competitiveness as well as contributing to the urban infrastructure, serving as a convenient source and ensuring the quality of life was abundant. So, the urban effects of the water system have raised the capital's status. With the contribution of its pragmatic water system, Chang'an not only performed its urban function brilliantly, but also established itself more firmly as a capital city.

  • Generally, aggregate may limit the workability, strength and durability of concrete, and good concrete cannot be made with aggregate of bad property including low strength, bad shape and grading. But recently, it has been insufficient in quantity to collect good natural aggregate because of exhaustion of aggregate resources. In case of Korea, the using ratio of crushed stone occupies about 97 percent of total coarse aggregate, and ratio of crushed sand occupies about 18.3 percent of total fine aggregate. This is an experimental study to compare and analyze the properties of crushed sand for concrete in capital region and concrete according to the replacement ratio of crushed sand to improve quality and mix design of concrete using crushed sand. According to test results, it was found that nearly all the properties of crushed sand satisfied with the value recommended by KS. And it is recommended that FM of crushed sand should be lowered by improvement of manufacture system or grading adjustment should be used because FM of crushed sand was a bit higher.

  • Generally, aggregate may limit the strength of concrete, and aggregate with undesirable properties including strength, shape and grading etc. cannot produce good concrete. Also, the properties of aggregate greatly affect the durability and structural performance of concrete. Recently, it has increased the using of crushed aggregate for concrete due to the exhaustion of good natural aggregate. In case of Korea, the using ratio of crushed stone occupies about 97% of whole coarse aggregate, and ratio of crushed sand occupies about 18.3% of whole fine aggregate. This is an experimental study to compare and analyze the properties of crushed sand for concrete in capital region and concrete according to the replacement ratio of crushed sand to do suitable mix design and improve the concrete quality. According to results, it was found that nearly all the properties of crushed sand satisfied with the value recommended by KS.

  • For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

  • The Environmental Kuznets Curve Hypothesis postulates an inverted-U shaped relationship between GDP per capita and various pollutants. Pollutants emission increases up to a certain level as income goes up; after that, it decreases. This paper investigates the relationship between industry pollutants taking industrial sulfur dioxide omission as example, and economic growth by using province-panel data set from 1989 to 2004 in 28 provinces of P. R. China. The result shows that the EKC hypothesis may be supported in the case of industrial sulfur dioxide, and the GDP per capital of turning point is about RMB 13,548 (at 1978 price). Except Shanghai, all the provinces GDP per capital in this study are less than RMB 13,548, indicating the amount of industrial sulfur dioxide emission will be increasing in the near future. To realize sustainable development and pollutants abatement, the central and local government should adopt an integrated strategy to protect environment.
