  • 본 연구에서는 지진 예지 연구를 위하여 한반도에서 발생한 MMI 진도가 VIII 보다 큰 역사 지진들의 전진들에 대하여 지진활동도의 변화를 분석하였다. 한반도에서의 강진에 대하여 13년의 전진기간과 진앙을 중심으로 위도 $1.1^{\circ}$, 경도 $1.1^{\circ}$ 크기의 사각형 모양의 전진범위를 가정했을 경우 가장 안정적인 전진들의 b값을 도출할 수 있었다. 이 전진기간과 전진범위에 의해 결정된 11개의 MMI 진도 VIII 이상의 강진의 전체 전진들에 대한 b값은 전체 역사지진의 b값인 0.36에 비해 확연히 작은 0.27로 결정되었다. 또한 강진 발생을 앞두고 작은 b값을 가지는 지진들이 강진의 진앙 근처에서 집중적으로 발생하였다. 본 연구를 통해 십 수 년 동안의 b값의 변화를 자세히 관찰함으로써 강진의 예지가 가능하다는 것이 확인되었다.

  • This study aims to investigate the effects of fair value valuation of biological assets and bearer plants measured at historical cost on the cost of third-party capital. The study contributes to the agricultural sector and the International Accounting Standard - IAS 41, which has been modified to remove the requirement to apply fair value for bearer plants, one of the primary biological assets with no active market. For this, 182 companies from 39 countries were studied in the years 2020 and 2021, with information taken from the Thomson Reuters Eikon platform. The methodology involves regression by the ordinary least squares method based on the model of Daly and Skaife (2016). The results show that the biological asset at fair value does not influence the cost of debt and that the measurement of bearer plants at historical cost has no effect on the cost of debt. Fair value did not change the perceived cost of debt of the analyzed companies in the studied period, contrary to Daly and Skaife (2016). Finally, the cost of third-party capital can be influenced by other aspects related to profit quality, which were not examined in this paper, such as profit management.

  • The fuzzy time series is introduced by Song and Chissom([8]) to construct a pattern for time series with vague or linguistic value. Many methods using the interval and fuzzy logical relationship related with historical data have been suggested to enhance the forecasting accuracy. But they do not fully reflect the fluctuation of historical data. Therefore, we propose the interval rearranged method to reflect the fluctuation of historical data and to improve the forecasting accuracy of fuzzy time series. Using the well-known enrollment, the proposed method is discussed and the forecasting accuracy is evaluated. Empirical studies show that the proposed method in forecasting accuracy is superior to existing methods and it fully reflects the fluctuation of historical data.

  • Seoul is an ancient city with a long history but there is hesitancy over referring to as a historic city due to the lack of traceable historic urban landscape elements which resulted from numerous invasions and general destruction. From a diachronic perspective, the nature which was survived the influence of development, could be the key element that links the past with the city's radically changed image in modern times. Although "old big trees" may be not a dominant influence with regards to the historical authenticity of the city, they are objects which contribute towards the historical authenticity by providing a sense of place in terms of connected narratives, as well as their natural image. However, the protection policy for an "old big tree" would place too much emphasis on the aspect of the ecological value rather than its cultural value. Generally, trees have been protected by installing a fence and a signboard around them as well as receiving additional care. However, it is difficult to find that surrounding space around the "law-protected tree" is connected with its original historical and cultural values. Even though the space around trees are no longer utilized in the same way as was so in the past, they still have high-potential in terms of cultural utilization. Therefore, the subject of this study is the "old big tree" as a natural object which contributed to the historical authenticity of Seoul. The current status of these "old big trees", aged between 100 and 800 years old, currently indicate that there are 215 trees designated as "law-protected tree" by the Seoul metropolitan government. This study aims to investigate the status of protection and utilization of the existing "law-protected trees" in the city of Seoul and find a way to increase both ecological preservation and cultural utilization for the high-potential "law-protected trees" within the city itself. In order to achieve this, previously researched papers shall be reviewed and surveyed pertaining to present usage patterns of the 215 "law-protected trees". In addition, five cases have been reviewed which focus on a few of utilizing the "protected trees" and their surrounding spaces. The results of the research indicate that 21 "old big trees" have high-potential in terms of cultural utilization as well as ecological value. However, it was revealed that there are limitations to pursue the value of preservation and utilization simultaneously throughout current regimental management. In order to cope with the current situation, it is pointed out that management facilities should be designed and installed by creative and flexible methods of organizing with consideration to the surrounding space and context. Even though in the case where there may not be a connecting history or legendary stories, the "old big trees" can serve as the fundamental features of small scale parks -dependent on their location, condition and environment- which will be of value to the local communities. This study could serve as a practical reference for the management and utilization of "old big trees" nationwide with numbers reaching 12,300 besides the city of Seoul.

  • In fashion, there are various cultural aspects that exist in complexity, where according to the era, even fashion items newly develop and prevail into various designs in the organic function with reality of related cultural phenomenon and aesthetic aim. Among the fashion items, the shoe is historically considered as the shield from lust and also the provision of praise against the most emotional incitement. Mankind has started wearing shoes out of the functional purpose of protection since the ancient Egyptian times. Thereafter humankind has been creating shoes artistically in respect to shape, color, and quality of material, etc, as an expression of aesthetical awareness and introspective desire for beauty. As modern fashion increasingly regards the total fashion image much more important than each items consisting the whole outfit, the role of shoe became essential more than ever. Contrary to its relative importance, little academic attention was given to this area yet, while prestigious museums and galleries in Europe and the USA have held exhibitions of shoes in view of both historical and artistic aspects. This study aims to make a historical inquiry of western shoes. through which their aesthetic values can be drawn. Literature on this subject including aesthetics, history of costume and arts were referred. Fashion magazines and catalogues were investigated for additional information. The process and results of this study are meant to be a suggestion not only to further studies but also to artistic and creative shoe design. Originated for the functional purpose, shoes have evolved in various shapes with different meanings attached to it. When the technological development made the satisfaction for functional needs possible, the intrinsic attribute, the aesthetic value was pursued. The historical contemplations of shoes from Egyptian times to the 1990's led to the results that the intrinsic aesthetic value of shoes can be summarized as follows: 1) protection and extension of body, 2) need for decoration, 3) erotic expression, 4) symbol of dignity and class, 5) fashion.

  • This study aimed to present the possibilities that a variety of conversions can be made in terms of the spatial function through the situation analysis and in-depth case studies, focusing on the cases of the conversion of historic buildings. Literature analysis and case analysis technique were conducted as the research methods. For the literature analysis, the researcher selected 105 cases of conversion-type buildings by recombining and reanalyzing them to space functional changes; the SPSS PC+ 18.0 program was used as the analysis tool to conduct a frequency analysis and cross analysis. In-depth analysis was conducted to investigate the overview of the architecture, building history, spatial functional changes, space program, conservation value, and the conserved parts by selecting 9 cases in Korean and foreign countries that have been recently converted through literature analysis and the results of the study were as follows. 1) As a result of analyzing the changes in function, the highest percentage of the cases was conversion into the cultural function (63.8%). 2) There were cases for conversion into the commercial function, business function, accommodation function and educational function besides cultural function. 3) As a result of spatial program, the attempts to increase the utilization of the building generally by applying the complex space with more than two functions could be seen. 4) The buildings with historical and architectural value were conserved most of the outer wall and some portion of internal parts; the buildings with symbolic value were renovated largely, while preserving symbolic parts; and the buildings with practical value were renovated in a way that maintains the structural parts while changing the interior space to be suitable for their function.
