This excperiment was conducted to investigate relation on seed dormancy and vi-viparous germination with sucrose content, fatty acid composition and abscisic acid content of rice seeds. The following results were obtained by this experiment. Sucrose content of brown rice harvested at 20 and 40 days after heading was higher in Japonica and Sare type varieties than in Tongil and Indica type rices. Positive relationship was found be-tween sucrose content of brown rice and viviparous germination rate of rice varieties tested.J aponica and Sare type rice varieties showed low proportion of oleic acid and higher proportion of linoleic acid in brown rice harvested at 20 and 40 days after heading than Tongil and Indica rices tested. Viviparous germination was negatively correlated with the proportion oleic acid and positively with that of linoleic acid. Abscisic acid content in hull of rice seeds stored for 30 days at 25/15$^{\circ}C$ fluctuation temperature condition was decreased more rapidly than 4$^{\circ}C$, and Japonica varieties tested showed lower con-tent of abscisic acid in rice hull than Tongil and Indica varieties used.

This study was conducted to know how low temperature response of rice varieties is available for breeding lines adapted to cold weather. Some agronomic characters related to cold tolerance were evaluated for 188 varieties including three varietal types of Japonica, Tongil, and Indica. Cold tolerance of Japonica and Indica type varieties varied in leaf discoloration, heading delay, reduction of culm length, panicle number, spikelet number, panicle exsertion, spikelet fertility, and phenotypic acceptability at maturity, while Tongil type varieties were susceptible in most agronomic characters. In leaf discoloration, most Japonica type varieties were highly tolerant, while Indica type varieties showed various responses from tolerant to susceptibility. Not significant difference among three varietal types was observed on reduction of panicle number and spikelet number due to low temperature.

This article reviewed the status of military force on the DMZ(demilitarized zone) without any confidential problems after literature reviewing on a ceasefire agreement and these powerful military force is judged to be a very serious setback to peaceful reunification of the Korean Peninsula. Also it suggests the ways to reduce inter-korean military force based on the political and economic phenomenon to preparing for an era of reunification of the Korean Peninsula. The easing of tension on the inter-korean military force is an essential element in building infrastructure of peaceful reunification. From now on, both Seoul and Pyongyang might check inter-Korea exchange cooperation Project and reconcile their differences. Primarily, The troops of DMZ would be minimized by Modernization for Military confidence-building. Increasing North-South hotline as possible further, it could contributes to ease of tension in case of emergency. Political and economic plans should be presented that do not arise the military tension simultaneously with ensuring political and economic aspects in the North Korea's regime.

The present study aims at estimating the model of bus bunching duration along with its influential determinants in an attempt to understand the status of bus bunching being created by buses from various routes converging into one bus stop. To do so, the duration analysis, a well-known survival analysis, was adopted in order to capture the distribution of duration time as for 8 base lines, accordingly developing the model best fit for weibull distribution. Key attention to draw out the duration time model for bus bunching phenomena was laid, by analyzing 18 impact factors, on such criterion variables as number of berth, number of bus line in each berth and maximum capacity of on-and-off passengers in each line. Comparison in two typical types of bus lane was made between bus-only center lane(Dobong Mia-ro) and normal street-side lane(Tongil Euiju-ro). In this regard, the study, based on the model as above, suggested appropriate alternatives to improve the bus operation by effectively controlling bus bunching.

A regular aperture occurs between persons controlled and a person governing the society according to national formation and development. A ruler is subdivided into a king, the President, or the highest controller who can feel the uncertainty of ruler's position. To protect those people, it is called guard that used all possible means and ways to protect those people or remove the danger. An opening of guard was related to enhancement of royal authority or centralism. Firstly a military organization had acted for this, but the organization gradually became independent according to it's subdivision and systematization. During the period of the Three States and Unified Silla, the guard was needed new management system by enhancement of royal authority, expansion of the territory, and establishment of centralism. The new management system that organized the group of vassal and Siweebu take charge of guarding the king or serving as private soldiers. In the end of Silla, as a wide range of reformation of government organization, the organization of vassal like Jungsasung and Sunkyosung that developed as not only guard the king and prince but also hold the business writing.

Purpose of this study is to develop the proceeding strategies for establishing of the DMZ World Peace Park in Korea which is one of projects of the Park Geun-hye's Government. We basically dissolute the conflict between the South and North Korea, and we build the atmosphere reconciliations and cooperation between two Koreas, and go forward the peaceful unification. And thus we make ultimately the world peace and establish enduring peace in the Korean Peninsula. Through the analysis the 8 proceeding strategies. Results of this study, I verified possibility of proceeding for establishing of the DMZ World Peace Park, and urgent need of policy development and support by the local governments, and we need to start the project in the South first.

Is obtain cell lines showing high level of rice cold tolerance, direct in vitro selection through cold stress on primary pollen callus derived from anther culture was carried out Genotypic difference in callus formation and plant regeneration was recognized Rates of albino was increased along the duration of cold stress. Reciprocal effects were not noticed in anther culturability There was no variants related to rice leaf discoloration in pollen derived lines from parental varieties, regardless of days of cold stress. The regeneration and recombination of rice leaf discoloration in 146 pollen-derived lines, 70 pollen-derived lines from cold stress at $0^{\circ}C$ for 10 days, and 830 F$_2$ plants presented normal distribution curves with skewness in tolerance and no significant difference among 3 populations. Direct in vitro selection for rice cold tolerance through cold stress on primary pollen callus derived from anther culture, therefore, was revealed ineffective as a in vitro technology.

Since a declaration between North and South Korea was adopted, North and South Korea has strengthened the interchange and cooperation between each other in many fields. Especially, the interchange and cooperation in the field of industrial property right, such as patent and trademark, are required to keep up with the age of the knowledge industry. But, until a recent date, there has been little interchange or cooperation in the field of industrial property right, and a few major companies were attempt to apply for the patent in North Korea through the Third country The system of industrial property laws in North and South Korea are very different because of time and political ideology barriers. To unify the system of industrial property laws in North and South Korea, firstly, North and South Korea must try to recognize and understand the dissimilarity between them. In this article, I compared the system of industrial property law of South Korea with that of North Korea to search commonalities and dissimilarities. Furthermore, it is needed to establish systematic devices for understanding of between North and South Korea, for instance, conducting a interdisciplinary seminar or dispatching a judge mutually. Finally, it is necessary to phase in a practical plan for unification. In the short run, mutual application and registration have to be authorized, and in the long view, unifying the practice of industrial property law service is needed. At the conclusion, the industrial property laws in North and South Korea can be unified systematically. In other words , to unify system of industrial property laws in North and South Korea, it is prerequisite that mutual understanding of industrial property laws and performance of the unify plan. The interchange and cooperation in this field will not only promote technical development but also create common interests of North and South Korea by expanding an opportunity for creating and utilizing industrial property.

There have been many researches on the optimal military size of unified Korea. However, most studies have used qualitative evaluation methods using subjective data. In addition, two studies incorporating statistical methodologies fail to derive appropriate results due to errors in selection of variables and the use of subjective data. Therefore, in this study, we use the ratio data instead of the country specific defense related data for 30 major countries in the world. We applied the logic of demand and supply of economics. The supply equations were produced by regression linear equation of the active ratio and defense ratio. The demand equations were produced as an inverse curves using the same coordinate system as the supply equation. With such a method, we estimated the appropriate military size and defense ratio for each of conscript and recruit system in unified Korea about 20 - 30 years later.
