Background: Several coastal regions in Vietnam have been suffered from salinity intrusion as a consequence of global climate change. However, there are limited studies on saline intrusion in Vietnam. This paper aimed to investigate the salinity intrusion of water and soil samples in paddy fields along Tam Giang lagoon, Thua Thien Hue province and clarify the factors affecting the salinity level. Methods: We measured the salinity concentrations (EC, Electrical conductivity) of water and soil samples in paddy fields at different distances (400, 600, 800, 1000 and 1200 m) from Tam Giang lagoon. The multiple regression analysis was performed to figure out the factors affecting the salinity concentrations. Result: The salinity concentrations of water were assessed as 48% high saline (10-25 dS m-1), 34% moderately saline (2-10 dS m-1), 2% slightly saline (0.7-2 dS m-1) and 15% non-saline ( less than 0.7 dS m-1). As for surface soil in paddy field, 14.3% moderately saline (4-8 dS m-1), 35.4% slightly saline (2-4 dS m-1) and 50.3% non-saline (0-2 dS m-1) were measured. A significantly positive correlation was found between salinity concentrations of water and soil (n = 175, r = 0.886, p less than 0.01). The distances from salinity sources, Tam Giang lagoon and shrimp pond, were major factors affecting the salinity concentrations. The paddy fields near Tam Giang lagoon and shrimp pond have higher salinity concentrations compared to those areas close to the residential area. The surface water in the paddy field within 1000 m from the salinity source was assessed as saline that might harm the paddy soil and rice production. The results of this study provide highly useful information for local policymakers and farmers about the status of salinity intrusion in paddy land.

The objectives of this research are: (1) to investigate the trend of paddy fields on Timor Islandand (2) to know the determinants of the conversion of paddy fields on Timor Island. TimorIsland consists of several districts such as Kupang District, South Central Timor District(TTS), North Central Timor District (TTU), Belu District and Kupang City. In fact, theyare the main rice-producing areas in the Timor Island, so they have an important role in thesupplying sufficient for locals. However, the regions are slowly started to be converted tonon-paddy-field use such as new settlements and other infrastructure development along withthe current economic development. The basic method used in this research was descriptiveanalysis and the location of research was determined purposively because this locationwas based on the consideration that there was a high growth of non-agricultural sectors inTimor Island; making it vulnerable to the reduction of paddy field area. The data used wassecondary data (2005-2014). The results showed that (1) the trend of rice field in Timor Islandis not significant with time variable. (2) The analysis of determinants of paddy field area inTimor Island using multiple linear regression with Ordinary Least Square (OLS) methodindicated that the factors affecting the conversion of wetland in Timor Island significantlyare the variable of building area and the number of industries.

AbstractWith changing time and lifestyle, general health of population has been drastically affected, and deteriorating quality of life. The transition from a traditional to modern lifestyle and consumption of diets rich in fat and calories combined with a high level of mental stress has compounded the problem further. Diabetes is one of the consequences of such a lifestyle change. Over the past 30 years, the status of diabetes has changed from being considered a mild disorder of the elderly to one of the major causes of morbidity and mortality affecting the youth and middle-aged people. This paper aims to present review of association between diabetes and quality of life as quality of life is considered to be one of the major factors affecting diabetes.

Soils collected from paddy fields were kept in a waterlogged condition in glass cylinders with and without drainage. After about 2 months of waterlogging soil samples were collected from each cm. depths of the cylinders, both from the bright and dark sides of the cylinders. The soil samples were analysed for iron, manganese and phosphorus. At the beginning these elements were uniformly distributed throughout the entire soil depth, but as a result of waterlogging a distribution pattern developed. More of these elements concentrated on the surface and illuminated sides of the cylinders. It is assumed that such a phenomenon also occurs in the paddy field. These elements by concentrating on the soil surface limit the feeding zones to the top 3–5 cm. of the soil.

The protection of agricultural land is very important to be studied scientifically considering the rapid growth of the population so that the possibility of land use conflict is very high. The main purpose of this research is to identify and inventory agricultural land of food especially existing rice-paddy fields to find zonasi agricultural land for sustainable foodcrops (ALSF) and agricultural reserved land for sustainable foodcrops (ARLSF)) with the level of threat from the transfer function in Gowa Regency area of hinterland Mamminasata, South Sulawesi. This study used a multiple criteria decision making approach with purpose mapping function of ALSF and ARLSF. The generic attributes, from: the biophysical aspects of the land (altitude, sizes of soil cracking, length of rice-field in slope landscape unit, proportion of paddy field area, top soil thickness), and socio-economic aspects (population density, population growth rate, demand for paddy field, productivity of paddy fields, equilibrium of paddy field), and policy aspects (local regulations status, detailed spatial plan status, type of irrigation networks). While the scenario of zonation of ALSF and ARLSF is used the criteria of distance from the provincial capital (Makassar) and the district capital (Sombaopu), the status of the rice-paddy field equilibrium and the trend pattern of percentage of space requirement. The results of the research shows that the existing position of paddy field is identified as ALSF and ARLSF zonation currently 24,210 Ha. The level of vulnerability of land conversion, which is in a "safe" position of 15,407 Ha (63.64%), and "threatened" of 8,803 Ha (36.36%). The prediction of productivity potential is related to the area of land that can be managed optimally in the vulnerable time up to the year 2020 covering 19,499 Ha (80.54%), and subsequently, by 2040 the area will shrink to only 10,173 Ha (42.02%).

Paddy field conversion occurs along with population growth followed by increased need for non-agricultural land. This research aims to formulate the direction control of paddy field conversion in Solok. Therefore it is necessary to analyze, they are scalogram analysis, and stepwise regression analysis. Paddy fields conversion in period of 2004-2014 in the Solok city 32,28 ha, mostly in the Lubuk Sikarah District. The threat of paddy fields conversion based of RTRW Solok city 2012-2031 is 403,60 ha (41,55%). Most of the villages in Solok belong to Hierarchy 1 except IX Korong with hierarchy 2 and Laing with hierarchy 3. The factors affecting of paddy field conversion in Solok city is land and building tax, land tittling, and the allocation of land for industrial, low density residential, high density residential, worship, and paddy fields allocation in the RTRW. Control direction of paddy field conversion in Solok city is to raise taxes on non-agriculture land, increasing the role of traditional institutions, community leaders and agricultural extension, zoning by setting RDTR of  Solok city, determination of food sustainable agricultural land (LP2B) and repair damaged irrigation networks.

The Comparative Study

This chapter adds a Chinese perspective to the comparative study of how national courts treat international law. The chapter finds that the application of international law in Chinese courts is influenced by several major factors, including China’s ambivalence toward international law, the role that the judiciary plays in China’s national governance, and the professional competence of Chinese judges. In particular, the failure of China’s Constitution to specify the status of international law makes secondary laws less likely to embrace international law: many secondary laws do not mention international law at all; only a modest number of secondary laws automatically incorporate international law. This also means that Chinese judges are discouraged from invoking international law in adjudicating disputes. However, in line with and in support of China’s economic opening policy since the late 1970s, Chinese judges regularly apply those treaties that deal with commercial relations between private actors. A major development is that, as China rises as a great power, Chinese courts have begun to prudently become more involved in foreign relations by applying international law.
