  • March 19, 1999, the renovation qf the runway of the Bo-Fai ai1field in Hua Hin, Prachubk-erikhan, Thailand, unearthed chemicals which were left over from the project "anch Hand Operation" held during the Vietnam war era. The chemical mixtures were analyzed by the US EPA, the Department oj Medical Sciences (DMSc), Ministry oj Public Health (MoPH) and the Pollution Control Department (PCD), the Ministry oj Science Technology and Environment (MOSTE) of Thailand, The samples were found to contain several defoliants used in the operation. They were 2,4-D, 2,4,5-T, Dicamba, Cocydelic acid, and Dioxins. Due to the complexity of the issue, the multiplicity of possible health effects, and the socio-economic implications for imports and exports, the Thai Society of Toxicology submitted a proposal to request World Health Organization (WHO), Geneva. The assistance is for the area of chemical safety and called for immediate action to explore the magnitude qf risk involved with Dioxins. In this paper we present our approach to health risk assessment which takes into an account the epidemiological studies of high-risk group exposed to the Ranch Hand operation. Dioxins are endocrine disruption chemicals which public concerns are developed due to presumption that a hazard exists (www.eva.gov/dioxins/html) for which current methodologies are deemed insufficient. The recent concepts of how oxidative stress toxicants may affect health end points and biomarkers of exposure of exposed individuals are discussed. While research activities are undergoing, The Thai Society of Toxicology do not anticipate significant risk to local residents and the environment due to our concurrence with opinion from the international experts invited by the World Health Organization proposed to the local experts at a workshop in Bangkok.n Bangkok.

  • At least, there are intense pressures on the natural habitats from various disturbance, including urbanization, extension of industrial area, and road construction. These human land use result in fragmentation of landscape and natural habitat. The ecological consequences of habitat fragmentation include the direct effects of habitat loss and the indirect effects of reduced inter-patch dispersal. The decline of biological diversity has been rapidly declined by the habitat loss and fragmentation. Conservation strategists should consider not only the habitat amount of that must be preserved, but also the spatial configuration of habitat across the landscape. But, the paucity of available data for most species forces landscape ecologists to develop the concept, model, and theory. The developed theories are often misused in academic papers and practical applications. The development history, presumption of concept, model, theory is ignored. This tendency have leaded to failure of landscape restoration and the use of theory in conservation practice have come under increasing attacks. This paper will highlight the ecological theory that have proven the most influential in landscape ecology, restoration and conservation : the theory of island biogeography, the theory of nested subset analysis, minimum viable population(MVP), the theory of metapopulation dynamics. And, it find the problem and usefulness of four theory in application to real world. Consequently, the understanding of theoretical implication about landscape ecological theory is required. We must carefully apply the theory after examining the problem and availability of various theory because of no existence of only one general theory.

  • This study proposed the new method of discerning the assembled parts and presuming the position of central point in a Cowl Cross Bar (CCB) using a Charge-Couple Device (CCD) camera attached to a robot in the auto assembly line. Three control points of an ellipse were decided by three reference points, which were equally distanced. The radii of these reference points were determined by the size of the object, and the repeated presumption secured the precise determination. The comparison of the central point of ellipse presumed by Randomized Hough Transform (RHT) with the part information stored in a database was used for determining the faulty part in an assembly. The method proposed in this study was applied for the real-time inspection of elliptical parts, such as bolt, nut hole and so on, connected to a CCB using a CCD camera. The findings of this study showed that the precise decision on whether the parts are inferior or not can be made irrespective of the lighting condition of industrial site and the noises of the surface of the part. In addition, the defect decision on the individual elliptic parts assembled in a CCB showed more than 98% accuracy within a 500-millisecond period at most.

  • This study attempts to provide a comparative overview of the liability systems Korean law and the PELS adopt, that is, the approaches taken by Korean law and the PELS to deal with various irregularities of contractual performance. In addition, it examines in a comparative way the questions of what is the position of the seller's liability for his delivery of defective goods under the chosen liability system and what is the legal nature of the seller's liability. The study finds that the dual liability system taken by Korean law has caused some complexities as to the matter of which liability is applicable in some borderline cases. The problem in such complexities is originated in that the remedies available and the limitation period applicable are differentiated in accordance with one's different categorization among three types of default under the general liability and defective performance under the seller's guarantee liability. In this light, the study argues that the unified liability system under the PELS is superior because its concept of non-performance embraces in a unitary manner all the aspects of default including defects in quality, quantity and title. In addition, it finds that Korean law has suffered endless debates on the question of what are the true contents of the same remedies of rescission and damages provided under the seller's guarantee liability as under the general liability. The debates have been come along on the basis of the traditional presumption among some of civil law jurisdictions that two liabilities be different in terms of not only their legal nature but also their contents of remedies. The study argues that the problem may be circumvented, first, by another way of thinking that the unified liability in Korean law is inferred from the specification of the identical remedies for both the general liability and the seller's guarantee liability under the KCC, second, by the preposition that the requirement of fault be depended upon what remedy the buyer seeks to claim rather than what liability he does to rely on.

  • There are so many study on Heumheum Sinseo as a lawbook. But the study on Heumheum Sinseo as investigation and forensic manual is uncommon. So this study was performed to find the value of Heumheum Sinseo as investigation and forensic manual. In Heumheum Sinseo, we could find the basic ideology of a sense of justice on humanitarianism and rationalism, and democratic thoughts on criminal law such as the presumption of innocence, speedy investigation clause and Limiting the admissibility of the confession. And so many scientific method on crime investigation are described in Heumheum Sinseo. We expect that this study serve as moment for us to be able to find it have 'practical' value to us.

  • The objective of this study is analysis of Andong-Dam lake water quality with water quality model. Model parameters of the WASP applied to Lake Andong-Dam were estimated. The methodology is based on grouping water quality constituents and relevant parameters and successively estimating parameters by a trial-and-error procedure. Water qualify system for modeling consisted of BOD, DO, T-N, T-P. The results of water quality modelling using WASP. T-N was maximum affected by K71C(Organic nitrogen mineralization rate) parameter. T-P was maximum affected by K83C(Dissolved organic phosphorus mineralization) parameter, and It did not show a difference almost from the parameter of others and it omitted. BOD was maximum affected by Temperature parameter, it was visible of the reaction due to the KDC(Deoxygenation rate) in afterwords, and it did not show a difference from the parameter of others and it omitted. DO was maximum affect by Temperature parameter, and It did not show a difference almost from the parameter of others and it omitted. The parameter which it presumes from the this study uses a water quality modeling and Actual value and the result with which it compares, error rate the parameter presumption which is appropriate with 1% interior and exterior is investigated, It will reach and it uses and it will be able to apply to the suitable parameter in water quality modelling of the objective area which can be feeded by it becomes.

  • This study is examine the scales applied to buildings in the age of Unified Silla through construction sites excavated and its results are as follows; First, scales used in the age of Unified Silla were varied like Jucheok, Dangcheok and Hancheok, but it was generally accepted that Dangcheok was used in Yeongjocheok Since it was found that the scales applied to Dabotap at the Bulguksa temple and main building of the Gameunsa temple belonged to Goguryeo, Yeongjocheok scale used early in the age of Unified Silla was transitional and it was thought that Goguryeocheok and Dangcheok were used togethar. Second, according to actual rulers in Korea, china and Japan, the length of Dangcheok(ruler used in Chinese Tang era) mostly belonged to the extent of $29.25cm\;{\sim}\;30.5cm$(central value: 29,71cm). Third, plane features of main building of temple are assumed that it had five rooms in front compartment until the 7th century and then it was diversified to three, five and seven compartment. The size of compartment was same in the scale of front Eokan and Hyeopkan until late 7th century, but since then the dimension of Eokan tended to be wider than Hyeopkan. It was judged that the front Eokan used triple scales like 9, 12, 15, 18 cheok. Fourth, the length of residential structures was 17.5cheok${\sim}$36cheok and Bcheok was commonly used for front side of structure, The length of official structures was 8.4cheok${\sim}$36.3cheok which is similar to residential structures. However it has been confirmed that each of 9cheok, 12cheok, and 15cheok has been used for Eokan and Hyeopkan which gave presumption that triple scales was used for the measure.

  • This research has been made through analyzing clothes of human dresses and ornaments appeared in the Buddhist pictures which were drawn at the times of the koryo Dynasty. Clothes of the Korea Dynasty could be analyzed as below : First, as for Turban (Doogun), common people used Ogun, Doogun, Byunsangmo and Chaek. For clothes, the style of the era of the ear of the Three-Dynasty. That is , they wore long shirts with narrow sleeves and narrow trousers and skirts. However, around the years of 1320, shirts had no more belt but became to show a kind of ribbon which is called as Gorum , and length of shirts was a bit shortened between hip and waist lines. Second, as for officials clothes, a kind of Rhangkan was used through the Dynasty but after the years of 1300, Wonryukwan was also used. In the clothes, Bangshimkikryung was used and the royals wore full-dress attire which looks like a long gown. Under the full-dress , we can see two different which seems to be a kind of present under-water. Third, in public clothes, same type of Danryung. Holl, belt and shoes were used throughout the Korea Dynasty. In addition Line (Yeon) was remarkably used skirt was dressed under Danryung by middle of the Dynasty the skirt was replaced with trousers. For Bokdoo, Jeonkak bokdoo was mostly used at the beginning of the Dynasty , but in the end of the Dynaty a lowr-flap bokdoo was in the main current. Meanwhile , we can see that the Korea Dynasty had its own in dependence in the clothes although the Dynasty was much affected by the Chines Song Dynasty System. We can hardly find a Mogrian cloethes style in the Korea-Dynasty clothes. Fourth, in Queen's clothes, banbi and pyo were used and sleeves were decorated with birds feather throughout the Dynasty. Lastly , famer's clothes are quite similar to those of the Chinese Song and won Dynasties and a decorative line was used in official clothes. These facts make us have a presumption of our Dongii culture might be conveyed to the Chinese in the ancient times but much more research is needed to clarify.
