What is the relationship between city diplomacy and public diplomacy in the United States? Whilst this question is often raised among scholars and practitioners of public diplomacy, a concrete and systematic response to it seems difficult to locate. This paper addresses the question by relying on earlier research based on empirical analysis of data from semi-structured interviews with city officials with international purview in the United States as well as with current and former officials at the U.S. Department of State who have worked on topics related to city diplomacy. The research and analysis that informs this paper and the diagrams it offers are hinged on design principles and adopt an architecture studio style approach to data analysis. Further, multidimensional scaling and correspondence analysis are used to visualize the convergence and divergence between the functions of public diplomacy, as introduced by Nicholas Cull, and the functions of city diplomacy that this paper introduces. This is done to first, provide a framework for understanding the dynamics between city diplomacy and public diplomacy; and second, uncover the policy intervention space that could guide policies for making U.S. city diplomacy and public diplomacy more strategically aligned.

본 연구의 목적은 국내에서 아직 연구가 미진한 와해성 기술에 대한 이해를 돕기 위해 컴퓨터 저장장치 산업을 대상으로 사례를 선정하고 실증분석 했다. 분석결과, 와해성 기술을 처음 제시했던 Christensen(1992)이 제시한 와해성 기술의 조건에 기존 저장장치인 HDD를 위협하고 있는 SSD가 모두 해당되는 것으로 나타났다. SSD는 HDD보다 기술적으로 우월할 뿐만 아니라 소형화, 경량화, 안정성으로 인해 다른 제품군에 응용이 가능하여 대량 생산이 가능한 것으로 나타났다. 이런 응용분야의 다양성은 대량생산을 가능하게하고 이로 인해 단위당 제품가격이 지속적으로 하락할 수 있는 가능성이 존재하여 추구 지속적인 기술의 확산이 예상된다. 본 연구의 결과는 와해성 기술에 대한 이해를 돕기 위한 실증사례를 제시함으로써 학계뿐만 아니라 실무진에게도 공헌하는바가 크다고 판단된다.

The process-based XBeach model has numerous empirical parameters because of insufficient understanding of hydrodynamics and sediment transport on the nearshore; hence, it is necessary to calibrate parameters to apply to various study areas and wave conditions. Therefore, the calibration process of parameters is essential for the improvement of model performance. Generally, the trial-and-error method is widely used; however, this method is passive and limited to various and comprehensive parameter ranges. In this study, the Generalized Likelihood Uncertainty Estimation (GLUE) method was used to estimate the optimal range of three parameters (gamma, facua, and gamma2) using morphological field data collected in Maengbang beach during the four typhoons that struck from September to October 2019. The model performance and optimal range of empirical parameters were evaluated using Brier Skill Score (BSS) along with the baseline profiles, sensitivity, and likelihood density analysis of BSS in the GLUE tools. Accordingly, the optimal parameter combinations were derived when facua was less than 0.15 and simulated well the shifting shape, from crescentic sand bar to alongshore uniform sand bars in the surf zone of Maengbang beach after storm impact. However, the erosion and accretion patterns nearby in the surf zone and shoreline remain challenges in the XBeach model.

One of the biggest change in the distributive market recently is that the development of private brand is progress actively since consumers purchasing behavior is tend to shift to resonable and practical planned purchase from brand image or brand name. Once the development of private brands is done successfully, the independent merchandising distinguished from other distribution companies is established, store image through customer satisfaction is strengthen and volume of sales and profit are increased. However, the existing studies in this field have not dealt with this matter systematically. Therefore, the purpose of this study is to propose an integrated framework within which to view private brand proneness. Factors found to influence private brand proneness included perceived cost, with private brand, perceived value for money, store fame, perceived risk, perceived quality variation between national and private brand products. Foe empirical analysis, the data were collected from 211 consumers who purchased the private brands in discount store and department store. With the collected survey data, reliability test, factor analysis for validity test and regression analysis for hypotheses test were conducted. Most hypotheses were accepted but on hypotheses were rejected negative relation of perceived cost and private brand proneness. Research results indicate that private brand proneness is affected by perceived value, perceived fame and there are negative relation between private brand proneness and perceived quality variation.
