The exemption clause of recurring shipments refers to the insurer's exemption in Short-term Export Credit Insurance for the additional shipment which was shipped on board while any foregoing shipment was unpaid beyond its due date over 30 days. The recurring shipments are constituted with two factors: the due date of the foregoing shipment and the shipment date of the additional export. The exemption clause of recurring shipments has been eased by extending the grace period for payment up to 60 days from 30 days for the transactions between exporters and importers having the history of payments which were made customarily in delay. This research argues that the current grace period is for the buyers who customarily delay their payments, and that the insurer introduce a grace period for shipment in favor of exporters for the additional shipment which was delayed in on-boarding due to reasons beyond the control of exporters. In consideration of the waiting time and the on-boarding time at ports for container freight, shipments are frequently delayed, which entails those shipments to be indemnified by the exemption clause of recurring shipments. Roll-overs and Blank Sailings also cause the container freight to be delayed in on-boarding. This research is expected to contribute to further development of Short-term Export Credit Insurance in K-SURE.

The purpose of this study were 1) to identify the differences between homosexual and heterosexual men in clothing behaviors(fashion leadership, preference for up-to-date style and sexual attractiveness), lifestyle and sex-role attitudes, and 2) to investigate the relation- ships between clothing behaviors and lifestyle and sex-role attitudes. The data was collected via self-administered questionnaires from 183 adult men(88 homosexual, 95 heterosexual men) living in Seoul, and was analyzed by factor analysis, t-test, correlations and multiple regressions. The result of this study were as follows: 1. Two factors of fashion leadership. were identified: fashion opinion leadership and fashion innovativeness. Four factors of lifestyle were identified: appearance awareness, self-confidence, authoritativeness, and achievement. 2. The result of t-test between homosexual and heterosexual men in clothing behaviors and psychological characteristics, homosexual men showed higher scores in fashion innovativeness, fashion opinion leadership, preference for up-to-date style, and appearance awareness of lifestyle characteristics. 3. From the result of analyzing the effects of psychological characteristics on 4 variables of clothing behaviors, appearance awareness of lifestyle characteristics was found to be the most influential factor for all the clothing behavior variables in both groups.

At the outset, surrealism starts from pure art, but surrealism has greatly influenced commercial art and fashion circles, more so than any other genre of art. The critical thinking methods of surrealism and its mode of expression continues to influence fashion theory extensively. Even now, surrealism may be found in the designs presented in fashion circles and is still expected for future lines. Surrealism in modern fashion has been reborn, newly integrated and transformed, based on the features of Surrealism paintings. The characteristics of its forms can be found in a combination of modern material, modern design and new skills and the classical items : bodyform molding context of architecture, experimental and sex-appealing of body. Expression was made by borrowing natural motives and recreating natural fabrics while the existing typical idea about clothes was destructed, with the boundary of patterns changed. Expression was also made by mixing items, uniting future images, and using up-to-date functional techniques. This study is significant that up-to-date technological culture expands cyber-space and increases surrealistic expressions by combined heterogeneous materials, thus arousing much interest. The purpose of this study is to determine interrelationship between how surrealism developed and what formative properties those clothes affected by surrealism obtained in the 1990s.

Mungbean is used for not only seed but sprout, so, consumption of mungbean has been on the rise in Korea. Life cycle of mungbean tends to be short among Legume. For that reason, Mungbean can be harvested for various cropping system and season per regions and farmers regardless of sowing date and harvesting date. So, Prior research is needed about growth characters and life cycle of mungbean per sowing period. Mungebean cultivar 'Dahyun' and 'Sanpo' supplied by Korea Agriculture Technology Promotion Agency(KOAT) is cultivated in wagner pot. Sowing period is proper time of seeding in Jeollanam-do and Gyeongsangnam-do that is major cultivation region of mungbean in korea from early May to mid July every 2 weeks. Length at maturity stage tends to increase from early May(sowing date: 4^th May) to early July(sowing date: 5^th July), but after that, It tends to decrease from mid July(sowing date: 19^th July). Number of branches and nods shows a similar trend. Length of pod has no tendency and no difference per sowing date. Number of pod per plants has also no tendency per sowing date. Test plots sowing in late May has the most number of pods.(Sanpo 22.9pods, Dahyun 16.8) Number of seeds per pod tends to increase to late May and Test plots sowing in mid July has the most number of seed per pod. In case of sowing at early May, Days of emergence is 7d. its summation of temperature is 132.2℃. After that, it tends to decrease to mid June. After mid June, Days of emergence is fixed to 3d. Average temperature growing up in this season, Summation of temperature from sowing to emergence takes the lowest point in test plots sowing in mid June.(Sanpo 88.6℃, Dahyun 88.6) Days of flowering tends to fasten from early May to mid July. Two cultivar shows same level. Days of maturity tends to fasten to mid June, after that tends to slow. In case that many research results about growth characters and life cycle mungbean per sowing period are drawn, it is expected that it result in increase of cultivation area and income of farmer.

The digital map expresses natural topography and artificial things with 3D position coordinates in the computer such as the road, railway, building, river, mountain, paddy and dryland. Therefore, those should contribute to the information-oriented society by maintaining information and providing it to users quickly. However it is difficult to maintain the most recent topographic information all the time because of restricted budget and time. The purpose of this study is to investigate and analyze the updating area of the digital map using remotely sensed data, and to furnish the useful information reducing cost and time. To predict updating area of the digital map, we applied the urban changes analysis method to Landsat TM images from produced date of the digital map to up-to-date. Classification method for urban change analysis applied single band process algorithm. This study presents that updating area of the digital map is predicted by only the rate of 40% on total research area.

Sunrise and sunset times differ depending on location and date. Previous studies conveniently but monotonously applied day and night times set up. This research defined the daytime and nighttime while considering the time of twilight according to the date and the location of ship collision accidents. Classifying the frequency of ship collision accidents with this standard, we conducted a chi-squared test for the difference between daytime and nighttime. The frequencies of ship collision accidents according to daytime and nighttime was compared by season, month, and time, and all of them showed statistically significant differences. The highest number of daytime ship collisions was 11.6 %, in June, and nighttime collisions peaked at 13.7 %, in December. The most frequent hour for daytime ship collisions was 0700h-0800h, at 10.2 %, and nighttime collisions peaked between 0400h-0500h, at 16.9 %. It is clear that the criteria used in previous studies cited was applied without any theoretical basis and likely only for the convenience of the researchers. It was found that results depend on what criteria are applied to the same research data. This study shows that statistical analyses of marine accidents, traffic volume, and congestion density should be carried out quantitatively while considering daytime and nighttime hours for each particular location and date.

This experiment was conducted to determine optimal sowing date and method of Italian ryegrass(Lo1iuwr wzultiflorum. Tetrone) in paddy of Gyeong Nam area. Treatments given were four sowing dates(Sep. 30, Oct. 10, Oct. 20 and Oct. 30) and four sowing methods (broadcasting on tillage ridging, broadcasting on zerotillage ridging, boundless broadcasting and alternated drilling). The characteristics of growth, winter survival, yield(fresh and dry matter) and nutr~ent quality were observed. The results obtained are summarized as follows: 1. Winter survival and yield components such as plant height, and number of stem were the highest due to higher survival tillers at the sown time of Sep. 30(p<. 05). 2. Plants sown on Sep. 30 showed the highest fresh and dry matter yield. Yield was decreased as delaying the date of sowing. Fresh and dry matter yield sown on Oct. 10, were obtained 7600 and 1100 kg, respectively, aftenvardly sign~ficantly decreased(p< .05). 3. Effect of sowing time and method on chemical composition were not recognized. 4. Winter surviva: sown on boundless-broadcasting was lower(p<. 05) than those of sown on broadcasting on ridging and alternated-drilling. 5. Fresh and dry matter y~elds were the highest when sown on broadcasting on tillage ridging but that of sown on houndless-broadcasting was relatively low. 6. The growth and forage yield were enhanced by sowing up to Oct. 10 and by sown on broadcasting on ridging (tillage or zerotillage).

American options no doubt is invariably more popular than European options, due to the fact that it gives the owner the option to exercise a contract before and up to the expiration date, unlike an European option, which only allows the owner to exercise a contract on the date of expiration. Owing to its popularity, many methods like the binomial numerical method and the pseudo American method have been devised for computing of the value of the American options. The aim of this research is to develop an effective 3-dimensional visualization for American option portfolio based on the Geske-Roll-Whaley model. It is obvious that it is extremely tedious and unadvisable for researchers to interprte chunks of data by looking at graphs or pie charts, which are simple but not effective for analyzing important dta. Hence, the generation of the Geske-Roll-Whaley ...
