Forfaiting is a trade finance facility whereby financial institution purchases accounts receivable from exporters on a without recourse basis to resolve exporters' credit risk. Since the effectuation of Uniform Rules for Forfaiting(URF 800), exporting companies have been interested in forfaiting and foreign exchange banks in South Korea have expanded products related to forfaiting. However, the risk management for dealing with forfaiting needs improvement. In this paper, we will compare current forfaiting risk managements between foreign exchange banks and foreign banks in South Korea by studying the agreements for each bank and standard forfaiting agreements of the ICC. There is a significant gap for risks covered and points of reserve(points of recourse) between each bank. This work suggests the need for unification for these gaps in order to enhance risk management for exporting companies and foreign exchange banks in South Korea.

The Directional sign system in Korean high speed railway stations has a lot of problems. For an example, It lacks of consistency in the shape or allocation. Also, the signs do not match with the actual directions sometimes. Last but not least, the view is blocked by the other signs such as advertisement or other barriers. We suggested the methods to standardize the sign systems that include visibility, accuracy, consistency, and simplicity. First, we categorized signs into directional signs, locational signs, and infomational signs. Then, we examined the actual high speed railway stations in Korea to learn the real situation. Finally, we suggested the methods to standardize the sign systems considering the factors that are visibility, accuracy, consistency, and simplicity.

This study was conducted on the premise of the development of cultural products using relic assets of traditional culture in a knowledge and information society led by culture and soft power. It was conducted in the context of exploring the possibility of cultural content products of Wa-Dang relics excavated from traditional architecture in the Unified Silla Period and expanding the scalability of commercialization motifs that are highly useful in jewelry design. First, the original form, material, use, size, meaning, and formative aesthetics of Wa-Dang were identified through literature and media research. Among the considered Wa-Dang, 10 types of Wa-Dang which represent the category and have values in modules and patterns were selected, and, then, circular images were extracted and modularized with a "formal simplification technique." Based on the "mathematical symmetry analysis technique," which is a method of systematizing pattern composition arrangement format. we derived a planar formative element that can be used in the development of the cultural content industry and jewelry design. In order to expand its usability in the jewelry industry in the future, it was presented as a 2D digital image. In the future, we hope more studies on the various cultural content industry utilizing the traditional culture will be carried out.

The experiment was studied to know the competitive ability of rice against weeds as affected by rice maturity and plant spacing. For both cultivars, Tongil (12 days later) and Yeongnamjosaeng, the least amount of weed was obtained from the 10 ${\times}$ 10cm plant spacing while no difference between 40 ${\times}$ (10 ${\times}$ 10cm) and 30 ${\times}$ 15cm plant spacings was observed. When weed was nor pulled out by hand, significant yield loss was resulted in 30 ${\times}$ 15cm and 40 ${\times}$ (10 ${\times}$ 10cm) plant spacings while no difference between weeding regime was observed at the 10 ${\times}$ 10cm plant spacing in both cultivars. Rice grain yield was unaffected by plant spacing for hand weeded plot in both rice cultivars. For noweeding plot, however, the highest grain yield was obtained from 10 ${\times}$10cm plant spacing and also this yield was not significantly different from the yield of hand weeded plot while significant yield loss was recognized at the 30 ${\times}$ 15cm and 40 ${\times}$ (10 ${\times}$ 10cm) plant spacings in noweeding plot. There was also a good relationship between weed weight and grain yield for both cultivars (Tongil; Y = 5.68 - 0.0127 X, r = -0.814$^*$; Yeongnamjosaengv Y = 5.04 - 0.0314 X, r =-0.9704$^{**}$). Based on these relationship, weed weight of 188.2g/sq.m for Yeongnamjosaeng and 223.6g/sq.m for Tongil was needed to reduce rice yield by 50%, respectively. This result implied that Tongil compete more efficiently against weed than Yeongnamjosaeng and hence, could be concluded that late maturing cultivar was more competitive against weed compared to early maturing cultivar.

This study speculates on responses to the nuclear threats of North Korea and mutual assistance and cooperation between South Korea, the U.S. and China for the unification of the Korean Peninsula. As for the North Koreas nuclear issue and unification of the Korean Peninsula, South Korea is the subject of national division, the U.S. is a responsible country in international issues and does not have diplomatic ties with North Korea. China is a traditional socialist nation and a supporter of North Korea. As North Korea's strategic weapons including nuclear weapons and ballistic missiles are international issues, to defend against Kim Jung-Eun's unexpected acts, the three countries should actively cooperate with each other and develop countermeasures. However, with respect to the road map of the North Koreas issue, there are subtle differences between the U.S. and China in recognition of and sanctions against North Korea as a resolution of the U..N. Security Council. The U.S. has continued a deterrence policy and sanctions against North Korea based on joint threats between South Korea and the U.S. while China has showed a negative position in the process of solving the North Korean nuclear issue because of the unstable security derived from the U.S. 's intervention in the Korean peninsula. North Korea should change its diplomatic policy in a more concrete way towards world peace although it has continued trade of strategic weapons with Middle Eastern countries to maintain its political system. For example, to restart the summit talks and open multilateral security channels. Although the issue of unification of the Korean peninsula should be resolved by South and North Korea themselves, it is strange that South and North Korea depend on the logic of powerful countries for the resolution of a national problem. As for North Koreas nuclear and the Unification issues, peaceful solutions presented by South Korea seem more persuasive than the solution presented by North Korea which did not secure any international support. However, South Korea, the U.S. and China need to develop uni-directional two-tract strategies for sanctions against North Korea and talks with North Korea for peace on the Korean peninsula, and should continue to support the economic independence of North Korea.

In order to investigate histopathologically the nature of varietal resistance and infection process of the rice bast fungus, Pyricularia oryzae. this experiment was undertaken by using the resistant cultivar Tongil and susceptible cultivars Norin No.6 and Jinheung in 1973 to 1974. 1) It was found that appressorium of the fungus forms not only at 4 hours after incubation under the favorable conditions but also peak of appressorial formation is at 48 hours treatment. Physical stimulus known to be a definite factor for appressorial formation. The optimum temperature range for appressorial infection was at $24^{\circ}C$ to $28^{\circ}C$, and pH was between 4.8 to 8.0 with 6.8 as the optimum. 2) Although percent of appressorial formation on the leaves of resistant Tongil and susceptiible Norin No.6 were only slightly different, there was a remarkable difference between resistant and susceptible cultivars with regard to percent of hyphal infection and index for hyphal extension. Index of hyphal extension was 1.6-2.7 in Tonyil. while in susceptible cultivar was 3.4-6.6. The rate of discoloration of infected cells, a indication of hypersensitivity, was greater in the resistant than in susceptible cultvar. 3) Therefore, it could be concluded that resistance of Tongil cultivar may be attributable to a higher degree of mechanical barriers as well as a higher level of antifungal substance accumulation.

This research is designed to evaluate perception of "the role of broadcasting in the process of unification" among South Korean propaganda broadcasting experts. This research used Q-methodology for in-depth evaluation of the experts' perception towards propaganda broadcasts. Total sixteen experts who work at the propaganda broadcasting company domestically or internationally as well as conduct related researches were selected as P-samples. This research listed sixty Q statements covering issues such as Perception of Unification, General Propaganda Broadcasts, Private Propaganda Broadcasts, Communication between North and South Korea. According to traditional way of Q-analysis, it drew two types of perception; Type 1: North Korean Liberal Broadcasts, Type2: Inter-Korean Exchange and Cooperation Broadcasts. For in-depth analysis, positive and negative statements were analyzed based on its tendency. As a result, positive statements tend to follow 'the Role of Unification Broadcasts' and negative statements followed 'the regulation of Private Broadcasts' When further researches were conducted on positive statements based on its axis of tendencies, Type 1 and Type 2 were categorized as follows; the Role of Unification Broadcasts- North Korean Liberal Broadcasts and Inter-Korean Exchange and Cooperation Broadcasts. On the other hand, when negative statements were analyzed based on its tendencies, the result of Type 1 and Type 2 were as follows; the Improvement of Private Broadcasts- Redeeming the Private Propaganda Broadcasts and Criticizing Private Propaganda Broadcasts. Regardless such differences, experts do agree on the idea which emphasize the role of broadcasts in the process of unification and also they share the same thought on the need to improve the private propaganda broadcasts. This research expected to contribute to society by making differences in analyzing propaganda broadcasting experts' perception in an objective and positive way compare to other existing researches. Therefore, it proposes several suggestions to consider when producing propaganda broadcasts.

In order to establish fertilizing technique for the increase of grain yield and its stability, the total absorbed amount of nutrients and nutritional status of rice plants at different growth stages were studied with respect to the nutrient contents and its relation to grain yield and yield components. This experiment was carried at three different level of nitrogen fertilization; two different seeding and transplanting times, and eight cultivars including both Japonica-and Tongil-type. The results of a part of these experiments are summarized as fallows: 1. The culm length tended to Increase with increasing fertilizer amount, but no significant difference between ordinary and heavy fertilization was observed in Tongil-type cultivars. 2. The panicle length was some what longer in ordinary and heavy fertilization than non-fertilization. 3. As the N-fertilizer level increases, the number of panicles per plant increased with higher response in Japonica-type cultivars than in Tongil-type cultivars. 4. The number of grains per panicle increased significantly in ordinary and heavy fertilization, compared to non-fertilization, but the difference in grain number per panicle among fertilizer treatment was smaller in Japonica-type cultivars than Tongil-type. 5. The 1,000 grains weight showed no significant difference among fertilization levels in ordinary transplanting, but indicated gradual decreasing tendency as the transplanting delayed. 6. In percentage of ripeness, there was no significant difference in ordinary transplanting, but hightly significant in late transplanting among N-fertilization levels and cultivars. 7. In yield, highly significant difference was shown among N-fertilizer levels and cultivars In Tongil-type variety, higher yield was obtained in ordinary fertilization than heavy fertilization. 8. The straw weight showed the tendency to increase in higher nitrogen level, but no significant difference between ordinaly and heavy fertilization was observed in Tonsil-type cultivars.

This study examines the state of archeological research on Silla and Unified Silla conducted in North Korea and identifies its characteristics. In South Korea, most research has focused on prehistoric times in North Korea, and little research has been done on Silla and Unified Silla. Noting this, we attempted to examine the history of archaeological research in North Korea to provide foundations upon which to go forward. The research was examined in terms of general archaeological themes including tombs, fortresses, the capital city, earthenware, roof tiles, ornaments, weapons, and horse harnesses, and we identified four characteristics from the examination. First, Juche ideology had a great influence on interpretation of the unification of the three kingdoms. The Juche ideology was first proposed in 1955, and at the time, it was not fully established as an ideology but rather seen as constituting opposition to toadyism. Accordingly, the unification of the three kingdoms led by Silla was seen as amounting to collusion with foreign forces and was not acknowledged. A piece of evidence shows that this change took place around 1962. Second, an inclination to testify to the 'uniqueness' of the cultures of the three kingdoms is observed. The argument is that culture in the Korean peninsula has unique characteristics that set it apart from Chinese culture, and that the cultures of the three kingdoms share much in common. This inclination was not mentioned in research until the 1950s, and it can be seen as an effort to comply with Juche ideology and prove the principle of unity as stated in the national leader's instructions in the 1960s. Third, the influence of Goguryeo on the formation of Silla culture is emphasized. Related research explains that Baekje, Silla, and Gaya adopted the 'superior' culture of Goguryeo, and could establish 'uniqueness' of culture accordingly. It is claimed that an advanced Goguryeo culture was disseminated throughout Balhae and Unified Silla, and then to Goryeo, resulting in a true unification of the ethnic culture. Fourth, researchers in North Korea presume the Silla tombs and other relics to be far older than South Korean researchers' estimate. From a standpoint of highlighting the long history of Korea, they estimate the Silla Dynasty was founded in the early or mid-first century. Accordingly, archeological evidence that demonstrates the establishment of the state is dated as far back. Such an estimate is also indispensable in justifying the explanation that the chamber tombs of Goguryeo had a direct influence on Silla. These research characteristics which arose during the 1960s continue to be basic guidelines for North Korean researchers.

In order to confirm the effect of climatic consumption index (C C I) on the number of spikelets and yield of rice, 3 levels of shading rates such as 0, 25, 50% of full light were treated during the tillering stage, reproductive growth stage and ripening period, respectively, in a phytotron controlled with day/ night temperature of 20/10$^{\circ}C$ and 30/20$^{\circ}C$, and field at Crop Experiment Station, Suwon, Korea. The results are as follows: 1. As solar radiation decreased during the reproductive growth stage in 30/20$^{\circ}C$ or field condition, the number of spikelets per panicle was decreased due to the decrease of the number of differentiated secondary rachis branches and spikelets as well as the increase of the number of degenerated secondary rachis branches and spikelets. 2. Our results showed slight negative correlation between C C I of the reproductive growth stage and number of panicles per square meter and number of differentiated secondary rachis branches. On the other hand, there was highly significant positive correlation between C C I of the reproductive growth stage and the number of degenerated secondary rachis branches and spikelets, and negative correlation in number of differentiated spikelets. 3. The shading during the reproductive growth stage did not affect on the percentage of ripened grains and 1000 grains weight of hulled rice, whereas those were decreased with shading during the ripened period. 4. Influence of shading in each growing stage on the yield was severe in the order of ripened period, reproductive growth stage, tillering stage. 5. Respiration rate in Jinheung was higher than that of Tongil at low temperature, but reversed above 30$^{\circ}C$. Respiratory coefficients (Q$\sub$10/) of Tongil and Jinheung were 2.74 and 1.96, respectively. Respiration/ photosynthesis ratio in Jinheung was higher than that of Tongil at low temperature, while higher in Tongil above 32$^{\circ}C$. 6. Transportation of $\^$14/C was restricted at 20/10$^{\circ}C$ in Tongil, however, there was no differences at 30/20$^{\circ}C$ in both Tongil and Jinheung. The influence of shading on the transportation of $\^$14/C did not affect at 20/10$^{\circ}C$, but it was hampered with shading at 30/20$^{\circ}C$ in both varieties.
