Operational risk is defined as the risk of loss resulting from inadequate or failed internal processes, people and systems, or external events. The advanced measurement approach proposed by Basel committee uses loss distribution approach(LDA) which quantifies operational loss based on bank's own historical data and measurement system. LDA involves two distribution fittings(frequency and severity) and then generates aggregate loss distribution by employing mathematical convolution. An objective validation for the operational risk measurement is essential because the operational risk measurement allows flexibility and subjective judgement to calculate regulatory capital. However, the methodology to verify the soundness of the operational risk measurement was not fully developed because the internal operational loss data had been extremely sparse and the modeling of extreme tail was very difficult. In this paper, we propose a methodology for the validation of operational risk measurement based on bootstrap confidence intervals of operational VaR(value at risk). We derived two methods to generate confidence intervals of operational VaR.

While opportunities for international construction firms have been growing with globalization, the risk of international construction projects is significantly increasing in severity and complexity. However, the traditional risk management approach in the construction industry has maintained a profit focus. In addition, this approach has not considered the overall risk at the corporate level, but rather has focused only on the risk of individuals at the project level. Corporate risk management should be implemented from the initial stages of new project selection. This paper suggests the Multi-criteria Integrated Systematic Analysis as a strategic decision-making tool for international construction contractors. The model integrates the multi-criteria of risk, return, and efficiency to choose the optimal set of new portfolios at the corporate level. This model also introduces the Value at Risk (VaR) concept to the international construction industry to present the total risk at the corporate level. To validate this model, this paper tested an experimental case study using the historical data of a global general contractor.

In order to satisfy customers' desire that is becoming more diverse, and to create the unique character of a product in the fast changing social structure and living environment, today's designers have to make efforts to provide new ideas continuously. In the twentieth century, the development of design in various aspects could be possible through an epoch-making progress of technology and industrialization, and thus the meaning and style of design has changed differently according to the current of the times. The retro design, which borrows the designs and styles which were popular in the past and recreates the design of modern meaning and concept, is widely applied now and in the spotlight as a latest design trend. This phenomenon of revival style appears as an image that makes us recollect the past in various fields while being recognized as an another value of new sense. Considered from the history of style changes for the past 100 years, the automobile design, the most representative in product design fields, has gradually changed in its types according to continuous historical, social, and cultural changes and technological progress, while a variety of designs have been continuously presented. The recent current of automobile styles, according to the rapid progress of advanced scientific technology, shows the fast and various changes and the retro style is becoming a new trend arousing people's interests and reintroducing the past designs. The revival trend in automobile designs is expected to stimulate human sensitivity and restore humanity on a different level before the trend, and also expected to be recreated as a new design trend in modern sense, connecting us with the past culture and expanding the realms of future designs.

'Waiting for a Thousand Years & Mingling with World People-Gangneung Danoje Festival 2017 as an Important Intangible Cultural Property' is the festival with the longest history in Korea. In spite of its historical value, however, there are not many academic researches on the value of festival brand equity. Thus, the objective of this study is to empirically analyze the influence relationship between selection attributes of festival storytelling, brand equity, brand attitude, and brand loyalty through the structural equation model. Regarding the spatial scope of thesis material, a survey was conducted focusing on 657 tourists visiting the Gangneung Danoje Festival. In the results of verifying the hypotheses in accordance with the structural equation model, the selection attributes of festival storytelling had effects on the brand equity, and the brand equity had effects on the brand attitude and brand loyalty while the brand attitude had effects on the brand loyalty. Based on such results of this study, the implications could be suggested as follows. First, the local contents culture should be developed together with local experts and residents by finding its local custom. Second, the brand equity that could prioritize the strategy of characteristics should be increased by emphasizing the selection attributes of storytelling. Third, the phased development should be achieved through local residents' open participation by dividing roles of experts and non-experts as festival manpower.

Climate change causes changes in rainfall patterns, temperature and drought frequency. Climate change impact influences on water management and crop production. It is critical issue in agricultural industry. Rice is a staple cereal crop in South Korea and Korea uses a ponding system for its paddy fields which requires a significant amount of water. In addition, water supply has inter-relationship with crop production which indicates water productivity. Therefore, it is important to assess overall impacts of climate change on water resource and crop production. A water footprint concept is an indicator which shows relationship between water use and crop yield. In addition, it generally composed of three components depending on water resources: green, blue, grey water. This study analyzed the change trend of water footprint of paddy rice under the climate change. The downscaled climate data from HadGEM3-RA based on RCP 8.5 scenario was applied as future periods (2020s, 2050s, 2080s), and historical climate data was set to base line (1990s). Depending on agro-climatic zones, Suwon and Jeonju were selected for study area. A yield of paddy rice was simulated by using FAO-AquaCrop 5.0, which is a water-driven crop model. Model was calibrated by adjusting parameters and was validated by Mann-Whitney U test statistically. The means of water footprint were projected increase by 55 % (2020s), 51 % (2050s) and 48 % (2080s), respectively, from the baseline value of $767m^2/ton$ in Suwon. In case of Jeonju, total water footprint was projected to increase by 46 % (2020s), 45 % (2050s), 12 % (2080s), respectively, from the baseline value of $765m^2/ton$. The results are expected to be useful for paddy water management and operation of water supply system and apply in establishing long-term policies for agricultural water resources.

A city is an ordinary space and a place of living that is directly related to our lives. An ordinary space is the total products of culture and the target of cultural representation. An aging residential area of a city reflects the ordinary lives of ordinary people along with its unique history; therefore, this place should not be seen only from an economic and political perspective. The Wausan area is a place that best maintains the characteristics and scenery of an aging urban residential area within Gwangju metropolitan city. Through research into this area, it is possible to discover the meaning and true value of an aging urban residential area such as the close relationship between ordinary culture and placeness, the creation factors and process of placeness of an aging urban residential area, and the authenticity of a particular place. This area is a modern residential area of today's ordinary people, created on a topography of hills and hilly areas along with a historical value of 400 years. It is based on the Gyeongyangyeok of the Joseon period. This place may be described as a space where the dailiness of ordinary people is alive based on its alleys and the unique scenery formed by its alleys and vegetable gardens. The authenticity deduced from such placeness is that an aging urban residential area is a place where communicative and considerate human life and a cultural diversity of an atypical nature are alive, a place where an environment and humans coexist in harmony, and a place where the communal dailiness of residents still exists.

The article examines the main problems of land market formation in Ukraine. The article is devoted to the study of problems and prospects of land market introduction after the abolition of the ban on alienation. The advantages and disadvantages of lifting the moratorium on the purchase and sale of agricultural land are highlighted. The experience of such European countries as France, Germany, Latvia, Romania and Poland in regulating the market of agricultural lands is analyzed. The historical stages of market formation, features of state policy in this area are considered. The authors found that in these countries the market for agricultural land is well developed and works effectively, which has positive consequences for the economy of these countries. After analyzing the experience, we identified common elements of an effective mechanism for regulating the land market in European countries, which can be implemented in Ukraine. It is emphasized that after the opening of the land market it is necessary to prevent the concentration of a large number of agricultural lands in the hands of one person or close persons and it is necessary to create an effective supervisory body, whose main functions will be supervising sales prevention of speculation in the land market. Emphasis is placed on the need to improve legislation in the field of land, organizational and informational conditions for land reform. The Law of Ukraine "On Amendments to Certain Legislative Acts of Ukraine Concerning the Circulation of Agricultural Land" was analyzed, the adoption of which put an end to the systematic extension of the moratorium on the sale of agricultural land. The positive aspects of such reservations are noted, such as the gradual introduction of the land market, quantitative restrictions, the lower limit of the value equivalent, which can not be less than the normative monetary value. At the same time, the problem is that the lack of an imperative norm on termination of the lease agreement in case of refusal of the lessee to purchase such land at a price not lower than expert assessment, will negatively affect its price formation and actually make the landlord hostage.
