This study was carried out to investigate the effect of three different growth retardants for applying pot or bedding plant with 'Rialto', 'Elodie', and 'Raizan'. Ancymidol, uniconazole, and paclobutrazol were applied as a drench at various concentrations. In Oriental hybrid lily 'Rialto', no changes were observed not only plant height but also leaves and flowers in paclobutrazol treatment. But the growth of plant treated with ancymidol was inhibited above 30% compare to control regardless of concentrations. However, numbers of leaf and flower per plant were similar to those of controls. Plant height was similar to nontreated control in $1mg{\cdot}L^{-1}$ uniconazole treatment but that reduced about 30% in drench application of 5 and $10mg{\cdot}L^{-1}$ uniconazole. Asiatic hybrid lily 'Elodie' was not different in growth between application of paclobutrazol and nontreatment as 'Rialto'. While, in all ancymidol treatments, plant height was 50~60% shorter than that of control. Also, numbers of leaves were reduced and days to flowering were slightly delayed in $30mg{\cdot}L^{-1}$ ancymidol treatment as compared with the control. All traits except plant height of $1mg{\cdot}L^{-1}$ uniconazole were similar to control but there were differences of statistical significance between 5, $10mg{\cdot}L^{-1}$ uniconazole drench and nontreated control. Lilium ${\times}$ formolongi 'Raizan' like above two cultivars had no dwarf effect on height in paclobutrazol treatment. In drench application of ancymidol, plant height reduced over 60% than that of control regardless of concentrations. Especially, days to flowering were a little delayed with $30mg{\cdot}L^{-1}$ paclobutrazol treatment. Plant height of $10mg{\cdot}L^{-1}$ uniconazole was about 26% shorter than that of control, but other traits were no differences between uniconazole treatment and control. In result, the drench application of ancymidol and uniconazole was pretty effective for usage as pot lily without great changes of quantitative traits.

The experiment investigated effect of duration, temperature, and light condition during chilling treatment on growth and flowering of four Campanula species in a factorial experiment. Two parent species, Campanula punctata Lam. var. rubriflora Mak. and C. Punctata Lam., and their two $F_1$ hybrids, C. punctata Lam. ${\times}$ C. punctata Lam. var. rubriflora Mak. ('Jiknyeo') and C. punctata Lam. var. rubriflora Mak. ${\times}$ C. punctata Lam. ('Gyeonu'), were used. Plants were cultured in vitro for five weeks at $25^{\circ}C$ under about $75{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD before being chilled at 4 or $25^{\circ}C$ for 3, 6, or 9 weeks under a darkened or lighted (about $10{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD) condition. After chilling treatment, plants were transplanted to 10 cm pots filled with a commercial growing medium and were transferred to environment-controlled growth chambers and subsequently to a greenhouse to observe their reproductive growth. Growth of all species and flowering of a $F_1$ hybrid 'Jiknyeo' were affected by duration, temperature, and light condition during chilling treatment. The greatest growth and survival percentage were observed in C. punctata Lam. var. rubriflora Mak. The survival percentage was greater when plants were chilled in a lighted than darkened condition, whereas it decreased when plants were chilled more than six weeks in vitro. Among the four species tested, flowering was observed only in a $F_1$ hybrid 'Jiknyeo' with 62.5% flowering plants when it was chilled at $25^{\circ}C$ for three weeks under a lighted condition. Percent flowering plant was affected by duration, temperature, and light condition during chilling treatment. Three-week chilling at $4^{\circ}C$ under a darkened condition significantly reduced days to flowering. These results suggest that the low temperature requirement for flowering is not qualitative but quantitative in Campanula species. Further experiment with more number of plants is necessary to ascertain this conclusion.

To have a basic idea on the spectral reflectance signature in paddy rice canopy, we measured spectral reflectance from paddy rice canopy(Ilpumbyeo) using spectroradiometer (GER Inc. SFOV : 0.35~2.50 ${\mu}{\textrm}{m}$) in situ weekly or biweekly from transplanting to ripening stage. Spectral reflectance of the visible range (0.4~0.7 ${\mu}{\textrm}{m}$) was decreased to below 5% and then slightly increased again after heading stage in rice canopy. Meanwhile spectral reflectance of the near-infrared range (0.7~1.1 ${\mu}{\textrm}{m}$) was increased to 40~50% and then decreased a great deal after panicle initiation stage in rice canopy. Landsat TM equivalent band set ($\bar{p}$$_{TMi}$) was created by averaging spectral reflectance values to the real TM bands. Correlation analysis between the rice crop variables (LAI, total dry matter) and TM equivalent band set ($\bar{p}$$_{TMi}$) showed that LAI and total dry matter of rice were highly correlated with visible bands such as $\bar{p}$$_{TM1}$, $\bar{p}$$_{TM2}$, and $\bar{p}$$_{TM3}$. Ratio values ($\bar{p}$$_{TMi}$/$\bar{p}$$_{TMi}$) such as $\bar{p}$$_{TM4}$/$\bar{p}$$_{TM2}$ were also highly correlated with rice crop variables such as LAI and total dry matter.

Recently, the aspect of regulating the legal system in North Korea has increased in quantity and shows the improvement of the evaluation of the lack of systematic consistency in the past. North Korean legislation has been negatively criticized for its lack of function and role of the legislative body and ambiguity of the legal system. In particular, the newly adopted "Legislation Law" in relation to the revision of the legislative system of North Korea contains important and clear contents to understand the legislative system and procedures of North Korea. The contents of the "Legislation Law" can be found a glimpse of the process by which the framework and procedures of the North Korean legislative process are organized more systematically. The North Korean legislation provides legal and institutional grounds for promoting internal and external policies under the Kim jong-un's regime. North Korea is focused on the nuclear issue, so there is limited information on other areas. In light of this, the purpose of this study is to examine the legislative theory and system of North Korea, and outline the theoretical basis of North Korea's emphasis on strengthening socialist judicial life, the socialist legal system, and the state theory of socialist rule of law. In addition, it can be analysed the content of actual legal reform in light of North Korea's legislative theory and system. In the study, it will examine the legislative system of North Korea and its characteristics by examining the legislative process and legislative process of North Korea. Moreover, it can be compared the contents of the Legislative Law of China with the legislative process of the DPRK and examine its characteristics. We will look at the challenges to the legislative system in North Korea and look into the future direction of the legislation. Kim jong-un's announcement of the revised legislation until recently through the publication of the 2016 Supplementary Codes is an important data for the current state of the North Korean legislation. This is because it confirms the content of the laws and regulations already known through "Democratic Chosun(a newspaper issued by North Korea Cabinet)'s statutory interpretation." However, in the case of laws and regulations related to the North Korean political system, it is still a remnant of the lagging legislation that the announcement is delayed, or it remains undisclosed or confidential. North Korean laws are developed and changed according to the changes of the times. In particular, the contents of the maintenance of foreign investment and the foreign economic law system and related internal legal system are found to change in accordance with the development direction of the socioeconomic system. If the direction of Kim jong-un's regime is to be expanded to the path of reform and opening up in the economic sector, the revision of the related laws and regulations will accelerate. Securing the transparency and objectivity of the North Korean legislative process and procedures will help to broaden the understanding of the inter-Korean legal system and to seek institutional measures for inter-Korean integration. In the future, in-depth research on the North Korean legal system will be emphasized as a basis for ultimately forming a unified Korea's legal system.

This paper focuses on the integration aspect of operators to determine an improvement strategy for the operating system to enhance competitiveness of Busan Port. This Study proposes the following alternatives: valuation standards for the integration of operators, the road map for the integration period, the scope and role setting of integrated operators' participation of Busan Port Authority(BPA), and the separation and linkage North Port and the New Port operators. First, the valuation standards for operator integration should be based on international standards. Additionally quantitative factors such as financial situation, business performance and participating companies' profitability, and the qualitative factors such as management ability, technology, and labor relations should be considered. Second, the timing of North Port's operator integration should be prioritized in the short term in conjunction with the commencement of its phase 2-4, 2-5, and 2-6. The integration of New Port operators should provide a road map for a relatively long-term perspective. Third, the participation of BPA' integrated operators should be considered in terms of publicity as a policy coordinator between terminals and by pursuing the profitability of entering into overseas business by fostering Korean global terminal operators. The scope and role of participation ensures that the experience and technology of the terminal operation business is maximized. Fourth, because physically intergrating the North Port' operator into a single corporate form is difficult, initially establishing a special purpose company to maximize the effect of the integrated operation is necessary. Then, the operators decided to convert to a holding company given the termination of the lease term contract with the State or BPA, and ultimately proposed a merger into a single corporation.

Insurer's duty of declaration is based on reciprocity of principle of the highest good, and recently it is widely recognized in the British and American insurance circles. The conception of fiduciary relationship is no longer equity or the legal theory which is only confined to the nations with Anglo-American laws. Therefore, recognizing the fiduciary relationship as the essence of insurance contract, which is more closely related to public interest than any other fields. will serve an efficient measure to seek fair and reasonable relationship with contractor, and provide legal foundation which permits contractor to bring an action for damage against violation of insurer's duty of declaration. In the future, only when the fiduciary relationship is approved as the essence of insurance contract, the business performance and quality of insurance industry is expected to increase. Therefore, to keep well this fiduciary relationship, or increase the fiduciary relationship persistency rates seems to be the bottom line in the insurance industry. In this paper, we developed a fiduciary relationship maintenance ratio based on comparison by case, which is represented with usually maintained contract months to paid months, based on each contract of the basis point. In this paper we have developed a new business model seeking the maximum profit with low cost and high efficiency, management policy of putting its priority on its substantiality, as an improvement measure to break away from the vicious circle of high cost and low efficiency, and management policy of putting its priority on its external growth(expansion of market share).

External morphology, principal component analysis, cluster analysis, and vegetation were investigated to understand the taxonomic relationships and native environmental characters of Megaleranthis saniculifolia populations in four different habitats. Morphological characters such as calyx length and width, calyx index, presence or absence of serrate in calyx lobe, length of peduncle, branch of peduncle and fruit characters were useful for the identification of four different habitats. But, characters of plant height, bract and seed in four habitats were similar. The results obtained based on the principal component(PC) analysis of treated 96 OTU were divided into two groups by PC 1, 2, 3, and the sums of contributions for the total variance were 66.79%(PC1 31.3%, PC2 20.7%, PC3 15.8%, respectively), and only Mt. Taeki population was distinctly different from populations of other three habitats. In cluster analysis based on average linkage cluster analysis and Ward's method, there were similarities in the composition of clustered taxa, and each populations were not identified. Importance value by relative coverage and frequency appeared in M. saniculifolia(50.81%), Aruncus dioicus(12.64%), Corydalus turtschanovii(11.62%), Veratrum oxysepalum(11.45%), Anemone koraiensis(8.96%), Meehania urticifolia(8.76%), Filipendula palmata(7.06%), Aconitum pseudo-laeve(5.66%), Pseudostellaria palibiniana(5.45%) and Smilacina japonica(5.25%), respectively. These species were considered to be highly similar with M. saniculifolia. The highest importance value in all investigated sites was M. saniculifolia, but specific composition of high level different from each habitat. Average diversity of species was 1.40, and the highest in Mt. Kwangdeok(1.31), lowest in Mt. Jumbong(1.17). Average soil pH was 5.25 and similar in each habitat. Although the lowest content of K ion, but the highest the EC, water capacity, organic compound, Ca content were found in soil of Mt. Sobaek. Soils in Mt. Kwangdeok had the lowest content of EC, organic compound, Ca. Soils of Mt. Jumbong showed the highest of Mg content, but the lowest of water capacity, $P_2O_5$, and K contents.

On the seventh day of mounting male and feamale cocoons are distinguished. A part of those male and female pupae is irradiated for 40 min. with 1,000r-ray irradiation. Those eggs obtained from the irradiated pupae are divided into six groups of 5, 15, 45, 90, 720 and 2,400 minutes after laying. The cahanges of accid soluble phosphorus in the each group of eggs are as follows. 1. In the control group of the maximum quantity in acid soluble phosphorus was 1,456r/100mg D.P. in the 2,400 minutes group, while the minimum quantity was 1,233r/100mg D.P. in the 720 minutes group. 2. In the mated group of ＊irradiated female moths and control male moths, the quantity of acid soluble phoshorus was small as compared with the control group in the five minute group of 1,288r/100mg D.P. and in the 15 minutes group of 1,299r/100mg D.P. while the quantity increased to 1,484r/100mg D.P. in the 45 minutes group. The quantity began to decrease again to 1,400r/100mg D.P. in the 2,400 minutes group which was smaller than that of the control group. The quantity was slightly small in the silkworm eggs laid in the early stage when compared with that of mated group of ＊irradiated male moths and control female moths. Both groups showed the larger quantity in the 720 minutes group than that of the control group. The quantity of acid soluble phosphorus in the mated group of control female moths .and ＊irradiated male moths was larger in variation than in the mated group of control male moths and ＊irradiated female moths. 3. In the mated group of ＊irradiated male and female moths the largerst quantity was 1,760r/100ms D.P. in 2,400 minutes group and second was 1,736r/100mg D.P. in 90 minutes group, and third was 1,288r/100mg D. P., in 5 minutes group. Generally the quantity was small in silkworm eggs laid by the irradiated one in the early stage than the control group, but in the later period of egg the quantity began to increase more than that of control group.

The objective of this study is to increase awareness and interest regarding polar science and thereby aid in establishing the concept and future direction of polar literacy. To analyze the current status, textbooks based on the common school curriculum pertaining to polar topics were reviewed. Six countries that actively conduct polar science, namely Korea, France, Japan, Germany, the United States, and the United Kingdom, were chosen. Subsequently, 402 cases in 110 science and social studies (geography) textbooks of these countries were analyzed through both quantitative and qualitative methods. Based on the obtained results, the importance of polar research in geoscience education and the need for spreading awareness regarding polar research as an indicator of global environmental changes were examined. It was found that the primary polar topics described in the textbooks are polar glaciers, polar volcanism, solid geophysics, polar infrastructure, and preservation of geological resources and heritage. This demonstrates that the polar region is a field of research with important clues to Earth's past, present, and future environments and is also a good teaching subject for geological education. However, an educational approach is needed for systematically laying emphasis on polar research. The implications of this study are manifold, such as the establishment of a cooperative system between polar scientists and educators, extraction of core concepts for polar literacy and content reconstruction, discovery of new polar topics associated with the curriculum, diversification of forms of presentation in textbooks, and development of an affective image that is based on correct cognitive understanding. Furthermore, through the continuance of polar topics in textbooks, students can improve their awareness regarding polar literacy and polar science culture, which in turn will serve as the driving force for sustainable polar research in the future.

This article is an analysis of the status of the modern Korean novels translated into Chinese over the past five years and how they are perceived by readers. Translation of modern Korean novels over the past five years has a few important characteristics as the following. The first characteristic is diversity. Books written by the most representative modern Korean writers, like Lee Gwang-soo, Kim Yu-jung, Kim Dong-ri, and books of the authors with very unique ideas, such as Park Kyung-ri, Lee Mun-yeol, Shin Kyung-suk, Gong Ji-young, Kim Young-ha, Park Min-kyu, Cheon Myung-gwan, and Kim Ae-ran have been translated and introduced to the Chinese population. Secondly, there are active translation of the books written by female writers. Lastly, without the support of the Literature Translation Institute of Korea or the Daesan Foundation, the number of works translated and published is slowly increasing. As a result of the increasing number of translations, the quality of translation is improving. However, interest on the part of Chinese readers in the modern Korean novel is not very high. But, the works of authors like Kim Young-ha, Cheon Myung-gwan, Kim Ae-ran, and Park Min-kyu, who began their literary careers after the mid-90s, are drawing relatively more attention. The common features of such works are the novelty of the narrative methods, attachment to reality, and readability. The interest shown by Chinese readers is significant in explaining the two following factors. First, it is true that many modern Korean novels are available in China, but only those that have been read will continue to be read. Second, the indifference of Chinese readers to modern Korean novels is because they are not yet aware of the existence of such works. It is important to train professional translators who can properly translate literature and also to focus on introducing the differences in modern Korean novels through canonical translation. To achieve this aim, not only supportive policies, but also cooperation between researchers in the field of modern Korean literature, translators, and publishers is essential.
