  • Real-time rainfall monitoring is of great practical importance over the highly populated Indochina area, which is prone to natural disasters, in particular in association with rainfall. With the goal of d etermining near real-time half-hourlyrain estimates from satellite, the three-layer, artificial neural networks (ANN) approach was used to train the brightness temperatures at 6.7, 11, and $12-{\mu}m$ channels of the Japanese geostationary satellite MTSAT against passive microwavebased rain rates from Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and TRMM Precipitation Radar (PR) data for the June-September 2005 period. The developed model was applied to the MTSAT data for the June-September 2006 period. The results demonstrate that the developed algorithm is comparable to the PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks) results and can be used for flood monitoring across the Indochina area on a half-hourly time scale.

  • This study analyzes the characteristics of Western North Pacific (WNP) tropical cyclone (TC) activity and large-scale environments according to the Western Pacific (WP) teleconnection pattern in summer. In the positive WP phase, an anomalous cyclone and an anomalous anticyclone develop in the low and middle latitudes of the East Asia, respectively. As a result, southeasterlies are reinforced in the northeast area of the East Asia including Korea and Japan which facilitates the movement of TC to this area, whereas northwesterlies are reinforced in the southwest area of the East Asia including South China and Indochina Peninsula which blocks the movement of TC to this area. Due to the spatial distribution of this reinforced pressure system, TCs develop, move, and turn more to the northeast of WNP than those in the negative WP phase. Consequently, the characteristics of this TC activity in the positive WP phase are associated with the location of upper tropospheric jet further to the northeast. Meanwhile, TCs in the negative WP phase mainly move to the west from Philippines toward south China and Indochina Peninsula. Furthermore, due to the terrain effect caused by the high passage frequency of TCs in the mainland China, the intensity of TCs are weaker than those in the positive WP phase.

  • The seasonal mean wind direction and wind speed in a greater coasting area are investigated using the ECMWF(European Centre for Medium-Range Weather Forecasts) data for 11 years from 1985 to 1995. In winter, the main wind direction in Korea and vicinity, Taiwan and vicinity, and the North Pacific Ocean of middle latitudes is a northwesterly wind, northeasterly wind, and westerly wind respectively. The wind speed is strongest in the East China Sea, the South China Sea, and the North Pacific Ocean of low latitudes(Beaufort wind scale 5-6). A distribution pattern of wind direction in spring and fall is similar to that in winter. Seasonal mean wind speed is strongest in winter and the next is fall. The wind speed in summer is generally weak. However, that in the Indochina and vicinity is strong by the influence of Asian monsoon.

  • GPS measurements from Feb. 2002 through Mar. 2004 were used to estimate recent crustal movement across the Lai Chau - Dien Bien fault system in North-West Vietnam. Four GPS campaign data were processed and combined with appropriate constraints using automatic GAMIT/GLOBK run in order to estimate ITRF2000 coordinates, local horizontal velocity and extensive/compressive strain rates. ITRF2000 velocities are consistent with east-southeastward movement of Sundaland i.e. Indochina. Local velocities show not much left-lateral strike-slip of the fault system and derived strain rates are insignificant from zero at $95\%$ confidence.

  • At different times in the 19th century, the Straits Settlements and Cochinchina were both colonies that the British and the French captured the earliest in their process of invasion of Malaya and Vietnam, respectively. This study examines the transitional stage from the traditional school system to colonial school system in the Straits Settlements and Cochinchina. This could also be considered an experimental stage for building later education systems in their expanded colonies, namely British Malaya and French Indochina, from the closing decades of the 19th century to the middle of the 20th century. This study, exploiting various sources and applying the comparative approach, identifies the factors that affected the different attitudes and choices of policy towards traditional education models of indigenous communities (the Malays and Vietnamese) pursued by the British in the Straits Settlements and the French in Cochinchina.

  • Nguyễn Huy Thiệp is a pillar in Vietnamese cultural life after the Second Indochina War, and the fates of men and women at the beginning of Đổi mới (Renovation) is one of the prominent themes in his short stories. To show off sexual power, seek glory, and maintain his dominant position, Thiệp's heroes engage in a game of oppressing the weak, hunting animals, and harassing women. However, due to the complex changes in social life, moral values, and gender inequality, men in the postwar period quickly experienced the feeling of humiliation, impotence, and failure. In turn, the sophisticated aspects of masculinity demonstrate the cultural and ethical concerns of contemporary Vietnamese society. By exploring the multidimensional nature of masculinity expressed in Thiệp's stories, this study aims to resolve misconceptions about gender and the relationship between men and women in his work.

  • Levels of platelets and other hematological values were monitored in 21 Saimiri and 12 Aotus monkeys over a period of three weeks post·infection with monkey·adapted Indochina CDC-1 strain of Plasmedium falciparum. In both Snlinoiri sciureus boliviensis and Aetus nancymai karyotype-1 monkeys the severest thrombocytopenia was observed at 14 days post-infection coinciding with peak parasitemia, neutropenia, Iynlphocytosis, and anemia associated with severe hemoglobinemia and elevated fibrinogen degeneration products(FDP's), MCH and MCV profiles in Aotus monkeys decreased with ascending parasitemia. In contrast, these parameters in Saimiri were characterized by a significant compensatory increase correlating with parasitemia. In general, thrombocytopenia was one of the earliest clinical manifestations of the infection with the platelets returning to normal levels shortly after peak parasitenlia at 14 days. Platelet kinetics had a strong correlation with hematologic and parasitologic values in the Aotus nlodel. No consistent associations were observed between platelet kinetics and other parameters in the Saimiri model. These data indicate that the Aotus model for malaria is more predictable than the Saimiri. Further, platelet turnover rates and recovery provide a useful prognostic parameter during malaria infection. The results are discussed in relation to the value of the two species of monkeys as models for the pathogenesis of human malaria.

Vietnamese Syncretism and the Characteristics of Caodaism's Chief Deity: Problematising Đức Cao Đài as a 'Monotheistic' God Within an East Asian Heavenly Milieu

  • Caodaism is a new religion from Vietnam which began in late 1925 and spread rapidly across the French colony of Indochina. With a broad syncretic aim, the new faith sought to revivify Vietnamese religious traditions whilst also incorporating religious, literary, and spiritist influences from France. Like Catholicism, Caodaism kept a strong focus on its monotheistic nature and today Caodaists are eager to label their religion a monotheism. It will be argued here, however, that the syncretic nature of this new faith complicates this claim to a significant degree. To make this argument, we will consider here the nature of God in Caodaism through two central texts from two important stages in the life of the religion. The first is the canonized Compilation of Divine Messages which collects a range of spirit messages from God and some other divine voices. These were received in the early years of the faith. The second is a collection of sermons from 1948/9 that takes Caodaist believers on a tour of heaven, and which is entitled The Divine Path to Eternal Life. It will be shown that in the first text, God speaks in the mode of a fully omnipotent and omniscient supreme being. In the second text, however, we are given a view of paradise that is much more akin to the court of a Jade Emperor within an East Asian milieu. In these realms, the personalities of other beings and redemptive mechanisms claim much of our attention, and seem to be a competing center of power to that of God. Furthermore, God's consort, the Divine Mother, takes on a range of sacred creative prerogatives that do something similar. Additionally, cadres of celestial administrators; buddhas, immortals, and saints help with the operation of a cosmos which spins on with guidance from its own laws. These laws form sacred mechanisms, such as cycles of reincarnation and judgement. These operate not in the purview of God, but as part of the very nature of the cosmos itself. In this context, the dualistic, polytheistic, and even automatic nature of Caodaism's cosmos will be considered in terms of the way in which they complicate this religion's monotheistic claims. To conclude, this article seeks to demonstrate the precise relevance of the term 'monotheism' for this religion.

  • This study shows that frequency of tropical cyclone (TC) around Korea in summer (June-September) has positive relation with Arctic Oscillation (AO) in the preceding April. In a positive AO phase, each of anomalous cyclone and anomalous anticyclone is developed in low latitude and middle latitude regions of East Asia from the preceding April to summer. As a result, while anomalous southeasterly around Korea serves as a steering flow that TCs move toward this area is strengthened, northwesterly that reinforced in southeastern area of East Asia plays a role in preventing TCs from moving toward this area. In addition, due to this distribution of pressure systems developed in this AO phase, TCs tend to occur, move and recurve in further northeastern region in the western North Pacific than TCs in a negative AO phase. On the contrary, TCs in a negative AO phase mainly move westward toward southern China or Indochina Peninsula from Philippines. Eventually, intensity of TCs is weaker than those in a positive AO phase due to the terrain effect caused by high passage frequency of TCs in mainland China.
