As the "Guidelines for GHG Environmental Assessment" was revised, it pointed out that the developers should evaluate GHG sequestration and storage of the developing site. However, the current guidelines only taking into account the quantitative reduction lost within the development site, and did not consider the qualitative decrease in the carbon sequestration capacity of forest edge produced by developments. In order to assess the quantitative and qualitative effects of vegetation carbon uptake, the CASA-NPP model and satellite image spatial-temporal fusion were used to estimate the annual net primary production in 2005 and 2015. The development projects between 2006 and 2014 were examined for evaluate quantitative changes in development site and qualitative changes in surroundings by development types. The RMSE value of the satellite image fusion results is less than 0.1 and approaches 0, and the correlation coefficient is more than 0.6, which shows relatively high prediction accuracy. The NPP estimation results range from 0 to $1335.53g\;C/m^2$ year before development and from 0 to $1333.77g\;C/m^2$ year after development. As a result of analyzing NPP reduction amount within the development area by type of forest development, the difference is not significant by type of development but it shows the lowest change in the sports facilities development. It was also found that the vegetation was most affected by the edge vegetation of industrial development. This suggests that the industrial development causes additional development in the surrounding area and indirectly influences the carbon sequestration function of edge vegetaion due to the increase of the edge and influx of disturbed species. The NPP calculation method and results presented in this study can be applied to quantitative and qualitative impact assessment of before and after development, and it can be applied to policies related to greenhouse gas in environmental impact assessment.

Natural stream work has been implemented recently to improve the urban stream environment in Korean cities. Many plants planted in the early work have not survived because they were not suited to the site and therefore failed to adapt to the riparian environment. The objective of this study is to investigate the floral change at the riparian environment after completion of the natural stream work by comparing the differences between planted species during the work and the current species at the study site. The study site was the stream area between Yeongdohng 2 bridge and Yeongdohng 3 bridge at Yangjae-cheon Stream, Gangnam-ku, Seoul, which was the prototype site of G-7 project of the Ministry of Environment in Korea. The following conclusions were derived after doing this study: Among the 50 species planted during the work, 23 species survived in the stream zone, while 27 species did not. The species that did not survive were ornamental plants that were not appropriate for the riparian environment. Among the 144 species which appeared naturally, 77 species(53.5%) were annuals and perennials, which means the study site is still in ecological disturbance and does not have a stable status ecologically. Thus, it is necessary to select the plant species that can survive in the disturbed riparian environment.

This study was conducted to investigate methods to overcome serious problems in hedge making. The growth response of Enonymus japonica was investigated, using different sizes of nonwoven fabric containers. Changes of shoot length, fresh weight and chlorophyll contents were measured a period of growth in each size of container. The results of this study are as follows; 1) The maximum growth of shoot length in all treatments was observed in May and August. The significant difference was found in the smaller size of container containing a less amount of soil than the control. 2) The soil amount of rhizosphere for the production of a standardized hedge seemed to be over 2,400-3,600㎤ per plant. 3) The depth of containers had a greater influence on growth of shoot length than the width of containers. 4) The fresh weight in 40cm width containers and 30$\times$20cm containers was similar to the control, but the rest of the containers showed significant difference compared with the control. 5) A significant difference of chlorophyll content was found in A, B, C, D and G treatment but I treatment did not show significant difference at the 5% level.

This research analyzes the involvement of hermeneutics in architectural history and theory studies and its pedagogy in the West after the 1950s. The research focuses on representative architectural schools in the West. In particular, this paper examines from the curricula of Joseph Rykwert and Dalibor Vesely at the University of Essex to their former students who played a significant role in expanding the history and theory courses in the late 20th century in the North America such as Alberto $P{\acute{e}}rez-G{\acute{o}}mez^{\prime}s$ (McGill University) and David Leatherbarrow (University of Pennsylvania). Through their leadership and other related architectural historians' efforts: 1) hermeneutics have been applied in architectural history studies from the critical perspectives of post-modern philosophy; 2) hermeneutics help stimulate discussions of thoughtful architectural design, enabling strong interactions between design theories and the embodied meanings of buildings; 3) these schools have produced and involved many prominent scholars who actively practice and develop the discourse of architectural history and theory from the perspectives of hermeneutics; 4) Finally, the hermeneutic approach in architectural history studies has enlightened many achieved architects' thoughtful design practice and theories within the emerging context of regional criticism and international cross-cultural architecture.

Artistic font design has become an integral part of visual media. However, without prior knowledge of the font domain, it is difficult to create distinct font styles. When the number of characters is limited, this task becomes easier (e.g., only Latin characters). However, designing CJK (Chinese, Japanese, and Korean) characters presents a challenge due to the large number of character sets and complexity of the glyph components in these languages. Numerous studies have been conducted on automating the font design process using generative adversarial networks (GANs). Existing methods rely heavily on reference fonts and perform font style conversions between different fonts. Additionally, rather than capturing style information for a target font via multiple style images, most methods do so via a single font image. In this paper, we propose a network architecture for generating multilingual font sets that makes use of geometric structures as content. Additionally, to acquire sufficient style information, we employ multiple style images belonging to a single font style simultaneously to extract global font style-specific information. By utilizing the geometric structural information of content and a few stylized images, our model can generate an entire font set while maintaining the style. Extensive experiments were conducted to demonstrate the proposed model's superiority over several baseline methods. Additionally, we conducted ablation studies to validate our proposed network architecture.

This paper presents some of the results of a project whose aim has been to produce a full simulation model which would determine the efficacy of pesticides for use by both farmers and the bio-chemical industry. The work presented here describes how crop architecture can be mathematically modelled and how the mechanics of pesticide droplet capture can be simulated so that if a wind assisted droplet-trajectory model is assumed then droplet deposition patterns on crop surfaces can be predicted. This achievement, when combined with biological response models, will then enable the efficacy of pesticide use to be predicted.
