In this paper I examined trades of general bank In KTB212 Futures for patterns which are best described by the behavioral finance literature. I reported the statistics for traders of profit or loss traders, number of traders, total trader gross trading income, revenue per contract. Thess results are acquired from the revenue scale and the trade contract scale. When traders are ranked on the basis of performance, successful winning traders are short positions in the KTB212. This result appears more faithful to large scale traders. The evidence suggests that large traders are able to act on the information flow. The measure of success is as total income, and the relationship between position holding and success is clear.

Plastic injection mould have two kinds of trouble, one is in mould another in injection parts. Most of defects of the former take the cause in a design like in structure and working, the later weld line, transforming, sink mark, burning, flow mark, scratching, shading, black hole and so on. Most of problems of the later is difficult for making a clear definitely the reason of defects because of complexible. The purpose of this paper is to improve the quality of plastic injection mould and parts with inquiring the counter plan and rouble of the part of Flat TV Front Cover by flow control method and gas- assisted injection moulding. For minimizing defects from injection moulding parts, this paper was investigated with using computer aided injection mold filling simulations. Based on these numerical results, I established guidelines mould design and injection processing condition. As a results I got the improve of quality, minimizing surface defects moulded parts and troubles in mould.

In germinating pea, contents of enodgenous polyamine in the leaf and stem were determined, and protein content, peroxidase activity and pattern of isozymes were examined in the leaf treated with polyamines. During growth of the pea for 14 days in light condition, the polyamines in leaf and stem showed the highest level at the 5th day, and were decreased rapidly at the 7th day, kept almost constant level since then. The putrescine level was relatively higher than those of spermidine and spermine, and cadaverine was also detected. On the other hand, in the leaf treated with spermine (0.01 mM) protein content increased about 250% than that of the control, the peroxidase activity increased ore than 100% in spermine of 0.01 mM and 0.1 mM. In treating with putrescine of 0.1 mM the pattern of peroxidase isozyme appeared 4 new cathodic bands (pI 4.8, 5.6, 5.9 and 6.8) compared with the control, the clear cathodic bands (pI 5.6, 5.9, 6.4 and 6.6) were also observed in spermine of 0.1 mM. These results suggest that polyamines were important factor in the differentiation of pea at the early stage of germination.

The displacement of the prepositional object from PP (DPO) was strictly prohibited in Old English (OE). No matter how such a prohibition is theoretically analyzed, it seems clear that OE had some sort of constraint against DPO. In this paper, I address the issue of what motivated the constraint by explaining what made DPO so difficult in OE. In particular, on the basis of the discussion about relative obliqueness among OE NP arguments, I propose that what was behind the constraint is both a high degree of obliqueness of OE prepositional arguments, which was rigidly marked and represented by the preposition as an obliqueness marker, and the representation and maintenance of relative obliqueness among OE NP arguments.

A study of the property of Indolene-Methanol Plus High Alcolhols (MPHA) has been completed. The study invested the measurement of fuel properties. The fuel properties investigated are distillation characteristics, heating value, flash point, specific gravity and water tolerance. The alcohol concentration was varied from 0 to 100 percent by volume in clear Indolene. The measurement of fuel properties indicated that, in general, Indolene-MPHA blends have higher water tolerance, similar specific gravity, similar flash point and different distillation characteristics compared to Indolene-Methanol blends.

To improve the blood compatibility of cellulose membrane, 2-(methacryloyloxy)ethyl-2-(trimethylammonium)ethyl phosphate(MTP), which is a methacrylate with phospholipid polar group, and glycidyl methacrylate(GMA) were grafted simultaneously on the surface of membrane and the biocompatibility of grafted membrane was investigated. There was no difference of permeability between the MTP and GMA-grafted and the original cellulose membrane. The permeation pathway for a solute whose molecular weight was above 10$^{4}$ is maintained after grafting on the surface of membrane. The cellulose membrane grafted with MTP and GMA effectively suppressed thrombogenicity for the rabbit blood. This effect became more clear with increasing the surface distribution of phospholipid polar groups.

Mutual compensating concept between SIL(Solid Immersion Lens) and OL(Objective Lens) of NFR(Near Field Recording) is proposed, designed and manufactured to achieve a high NA and obtain a wider manufacturing tolerance. Tolerance information is present in article. An effective NA of Advanced SIL is 1.7 and adjustment between OL and SIL is carried out using our interferometer. We measured very clear RF signal using 3-axis actuator at Test bed.

Polarimetric measurements of the sky radiation by the PSR-I000, which is the multi-spectral polarimeter developed by the Opt Research Corporation and has the same wavelength regions (443nm, 490nm, 565nm, 670nm, 765nm and 865nm) as the ADEOSII/POLDER sensor, have been carried out at the ground station in Kanazawa city, Japan from March to May. First of all, the wavelength dependency of degrees of polarization is examined and it is shown that degrees of polarization measured under the hazy dust cloud are lower than those measured in the clear sky and decrease as the wavelength increases. Next, a new method for estimating optical properties, such as the optical thickness, the number size distribution and the refractive index, of the Asian dust and the ground reflectance from degrees of polarization measured by PSR-I000 is described. Finally, this method is applied to polarization data acquired on April 15,2002. As a result, it is shown that our estimation algorithm provides a good result.

The scale and the extent of a aging of population of a rural are more serious than those of a urban in China. However, the welfare policy and the service for the aged in the rural are inferior. China established the different systems of social welfare policy for the city and the rural and has administered it since the china was established. Owing to an open-door policy(opening of a reform) the gap between the two got more deeply distinguished. Accordingly. the striking difference is shown in a living environment and a quality of life of the cities and the rural. I made clear the difference of services for the aged in the rural and the urban examining daily lives, medical industry, recreation systems and so on and analyzing their sources. In addition, I proposed the ways to establish synthetic social welfare policy of the urban and the rural.

The purpose of this study is to make clear the identity of Korean traditional housing. And I'm trying to search characteristics of boundary in Korean traditional housing. In this study, I have analyzed boundary of ‘Gwan-gajung’. It is constructed on a square shaped plan, there is an elegant middle court, and a counter-roofed shrine house in the rear of the inner building. In this study, the definition of boundary is made based on what has been perceived as the proper structure, whose characteristics can be described in terms of openness, inside and outside parts and orientation. As a critical factor to spatial qualities, boundary is closely related with the connection and disconnection, background and atmosphere, and inferior and superior relations and hierarchical order from the view of space. The result of study is like followings. The characteristics of boundary in Korean traditional housing is 1. one way direction of penetrability, 2. having the face and the back 3. orientation 4. duplication.
