UCP 600 will now come into effect on 1 July 2007, giving practitioners more than six months to prepare for the change. The vote on the UCP was also a favourable vote on eUCP Version 1.1 which was amended to bring it into conformity with the new rules. ICC Banking commission unanimeusly approved the revised UCP 600 on 26 October 2006 in paris convention. The most important revision of UCP600 have altered the technical and difficult to understand wording of UCP500 into plain simple precise and concise language, The singuler achievement of UCP600 is its elimination of phrase like "reasonable care" "reasonable time" and "an it's face" from the rule. The introduction of separate articles 2 and 3 on "Definitions" and "Interpretation" which contain the concept of "honour" along with the inclusion of certain ISBP wording in UCP, should bring about far greater clarity and precision than in many of the contentions articles in UCP500. The definition of negotiation should help lay to rest the controversies surrounding the terms of negotiation. The removal of reasonable time and the replacement by five banking days should speed the process and make L/Cs more attractive in the market, nevertheless UCP600 have many problems in appling it in practical field. For example the definition of credit, negotiation and purchase it's accepted or undertaken payment draft by accepting bank or deferred payment bank, the second advising bark's position etc. so, I will introduce in this thesis the important revised articles of UCP600 and investigate the problems in applying it in practicle field with reference to the specialist's opinion of the practical field and ICC opinions of drafting Group.

Formation of filaments and subsequent dense cores in ISM is one of the essential questions to address in star formation. To investigate this scenario in detail, we recently started a molecular line survey namely 'Filaments, the Universal Nursery of Stars (FUNS)' toward nearby filamentary clouds in Gould Belt using TRAO 14m single dish telescope equipped with a 16 multi-beam array. In the present work, we report the first look results of kinematics of a low mass star forming region L1478 of California molecular cloud. This region is found to be consisting of long filaments with a hub-filament structure. We performed On-The-Fly mapping observations covering ~1.1 square degree area of this region using C18O(1-0) as a low density tracer and 0.13 square degree area using N2H+(1-0) as a high density tracer, respectively. CS (2-1) and SO (32-21) were also used simultaneously to map ~290 square arcminute area of this region. We identified 10 filaments applying Dendrogram technique to C18O data-cube and 13 dense cores using FellWalker and N2H+ data set. Basic physical properties of filaments such as mass, length, width, velocity field, and velocity dispersion are derived. It is found that filaments in L~1478 are velocity coherent and supercritical. Especially the filaments which are highly supercritical are found to have dense cores detected in N2H+. Non-thermal velocity dispersions derived from C18O and N2H+ suggest that most of the dense cores are subsonic or transonic while the surrounding filaments are transonic or supersonic. We concluded that filaments in L~1478 are gravitationally unstable which might collapse to form dense cores and stars. We also suggest that formation mechanism can be different in individual filament depending on its morphology and environment.

In Honam province, the cultural prototype are largely unknown to the people, also the research on this subject are scarce, the artistic excellence, somewhat under evaluated, both in our country and internationally. It is imperative that we develop the modern design using this prototype. thereby apply it to many areas of cultural products. We should extend the dimension not only to the local festival but also to the mass production resulting in the commercial gains. The Unjusa Buddha festival for promoting the public relation would be greatly benefited by using the concept of the temple, the local prototype, by which we expect to create a ingenious textile design pattern, coinciding with the main purpose of this study. The ancient material around Unjusa come to be the subject of our textile design by way of selecting the most remarkable ones of heritage among the materials of Unjusa. In the long run, the harmonious contrast of both traditional and modern image were sought in this study. Designed patterns were edited using Adobe Photoshop CS3, a multi-purpose graphic program and were simulated in the towel for visual presentation. The design is of two kinds, the one is of the free style using combinations of reclining Buddha, stone Buddha, stone pagoda, and geometric patterns freely not to be standardized. The other one is mixing of lotus pattern, reclining Buddha, and geometric patterns. These designs were applied delicately on the towel, necktie and handkerchief, and the various colors were suggested by the 6 color ways. The brilliance of our traditional cultural property should be noted by these designs and I hope that this study would be a help to develop our cultural prototype and make a product of using the outstanding heritage.

The purpose of this study was to observe corrosion characteristics of six dental amalgams and was to analyse corrosion products electrochemically. After each amalgam alloy and Hg was triturated as the direction of the manufacturer by using mechanical amalgamator, the triturated mass was inserted into the cylinderical metal mold ($12{\times}10mm$) and was condensed with 160kg/$cm^2$ by using the hydrolic press. The specimen was removed from the mold and was stored at room temperature for 1 week, and was polished with amalgam polishing kit. The anodic and cathodic polarization curve was obtained by using cyclic voltammetric method with 3-electrode potentiostat in saline for each amalgam and Ag, Sn, Cu plate specimen at $37{\pm}0.5^{\circ}C$. The potential sweep range was -1.7V~0. 4V(vs SCE) in working electrode and scan rate was 50mV/s and the exposed surface area of each specimen to the electrolytic solution was $0.79cm^2$. The results were as follows. 1. In anodic-cathodic polarization curve of amalgam specimens, two anodic current rising areas and two cathodic current peaks were obtained at the low Cu amalgam(CF, CS) specimen and three anodic current rising areas and three cathodic current peaks were obtained at the high Cu amalgam (TY, DS, HV) specimen. 2. As this compared with the anodic and cathodic current peak potentials of Sn, Cu and Ag specimen, the first cathodic current peak I c was caused by the reduction of divalent tin salt, second cathodic current peak IIIc results from the reduction of quadravalent tin salt, and third cathodic current peak me results from the reduction of copper salt. 3. As reverse potential sweeping was done repeatedly, anodic current was decreased slightly in all amalgam specimens.

Purpose: The purpose of this study was to assess the association of vocational interest and personality with temporomandibular disorders (TMD). Methods: Four hundred and fourteen college students in Gyeonggi-do completed Vocational Preference Inventory L form and a questionnaire and collected data were analyzed by R program. Results: The percentage of subjects who responded that they had at least one contributing factor for TMD was significantly different among 27 two-letter Holland codes (p<0.05). The two-letter Holland codes of which the first-letter was social (S) (S artistic [A], S investigative [I], S realistic [R], S conventional [C], S enterprising [E]) or C (CE, CS, CA, CI) had tendency of having the relatively higher prevalence of symptoms and contributing factors for TMD. Among 6 one-letter Holland codes, the prevalence of a symptom of frequent fatigue in the jaw and a habit of gum chewing showed the significant difference (p<0.05). E code seemed to have lower prevalence of a symptom of frequent fatigue in the jaw than other codes. S code appeared to use chewing gum more frequently than other codes. High scorers on emotional instability showed the significantly higher prevalence of TMD symptoms (p<0.05) and contributing factors for TMD (p<0.001) than low scorers. Furthermore, high scorers on emotional instability had significantly higher mean scales of the number of positive answers of TMD symptoms (p<0.01) and of contributing factors for TMD (p<0.001) than low scorers. Conclusions: Symptoms and contributing factors for TMD were related to emotional instability. Vocational Preference Inventory L form might be utilized in assessing emotional factors of persons with TMD symptoms.
