A modeling method for the impact analysis of plate structures employing Hertzian contact theory is presented in this paper. Since local deformation as well as bending deflection of the plate occurs due to the collision, it has to be considered for the impact analysis. When the coefficient of restitution is employed for the impact analysis, the local deformation is not considered. For more accurate and reliable impact analysis, however, the local deformation should be considered. The effects of the location of collision and the collision mass on the impact duration time and the contact force magnitude are investigated through numerical studies employing Hertzian contact theory.

This study identified the impact of the service quality of local food stores on customer satisfaction and revisiting intention of the customers as the interest into local foods is increasing. The main outcomes are as follows: First, many of the respondents said that they use the local food stores based on the trust in the origin of the products and good quality. Second, reliability and validity were suitable for factor analysis and the correlation had a positive (+) directivity. Third, reliability, assurance, empathy and tangibles were analyzed to have a positive (+) impact among the 5 aspects of service quality except for responsiveness. Fourth, customer satisfaction had a positive (+) impact on the intention to revisit the local food stores, and reliability, assurance and empathy had a positive (+) impact on revisiting intention at the statistical significance level except for responsiveness and tangibles among the 5 service quality aspects. Therefore, it is thought to be required to keep having interests into service quality to gain a competitive edge as a sustainable management system since the service quality of local food stores has impacts on customer satisfaction and intention to revisit.

본 연구는 그동안 지자체에서 시행해오던 환경영향평가 제도 현황 및 운영실태에 대한 분석을 통해 지자체 환경영향평가 운영체계의 성과와 한계를 파악하고 이를 개선하기 위한 정책 방안을 제시하는 것을 목적으로 한다. 연구 과제 수행 방법으로는 행정분권화에 따른 지자체 환경영향평가의 긍정적·부정적 영향에 대한 선행 연구 고찰을 바탕으로 서울시, 제주도, 부산시, 대전시 등 주요 지자체들의 환경영향평가 조례 현황을 분석하고 해당 지자체 담당 공무원들과의 심층 인터뷰를 통해 협의 및 운영실태, 그리고 제반 문제점들을 파악하고자 하였다. 분석 결과, 지자체 환경영향평가제도 시행의 주요 성과는 지역 특성에 부합하는 평가대상 및 항목의 선정과 지속적 평가관리가 가능하고, 자체적인 사후조사 관리 등을 통해 평가 협의 후 지자체의 모니터링 및 관리 감독 기능이 강화될 수 있다는 것이었다. 주요 문제점으로는 지자체의 장이 사업 승인권과 환경영향평가 협의권을 동시에 갖게 됨으로써 발생하는 의사결정과정의 문제, 환경평가 부서와 타 부서와의 업무협력 시스템이 유기적으로 작동하지 못하는 문제, 평가담당 부서의 조직과 인력의 열악함, 그리고 심의위원 전문인력 풀 확보의 어려움과 비효율적 운영시스템 등이 도출되었다. 또한, 평가 대상사업 및 범위의 조율 과정에서 중복규제 가능성의 문제가 빈번하게 제기된다는 것도 지자체 환경영향평가 제도 이행상의 주요 문제로 제기되었다.

This study aims to survey whether local governments have legislated laws and regulations on environment impact assessment system, to compare and analyze specific projects and their scale, assessment items, and procedures & discussion process, to identify issues and generate improvement plans, and to suggest a direction for future legislation to local governments that plan to legislate laws and regulations in the future. Major outcome of the study are as follows. First, terminologies used for environment impact assessment by local governments need to be unified. Also, laws and regulations need to be legislated soon. Second, in "urban development project" areas, a total of nine project areas including "quarrying of soil and stone, sand, gravel, and minerals" was essential common projects. A total of six project types were added or newly established compared to national systems. Among them, four project types were added within national-level project areas and two project types were not available under the national-level project areas and newly added due to the nature of local governments. Third, in terms of project scale, scale enhancement of "urban development project" was most common. Analysis showed that in case of clean natural environment such as Cheju Island, it is necessary to consider reinforcing project areas where development activities take place directly in forests or rivers such as "industrial base and complex development", "water resource development", and "development of tourism complex." Fourth, the discussion and review procedures of assessment reports were similar to those at government level. However, in case of Seoul city, it is required to write a "preparation plan" before drafting an assessment report. The city features partial introduction of scoping and screening, which allows to exempt discussion procedures if impact on environment is found to be minimal after drafting the assessment report. In case of national-level, it has a dual system that is split between Ministry of Construction and Transportation and Ministry of Environment. However, in case of environment impact assessment of local governments, it is a single system where city mayors and provincial governors are in charge of both project execution and environmental assessment. Therefore, the most important task is how to satisfy objectiveness and accountability.

RC 슬래브에 배근되는 철근비와 충격체의 충돌속도가 국부손상에 미치는 영향을 평가하기 위하여 일련의 충돌해석을 수행하였다. 해석결과, 철근비는 관입깊이 및 관통두께에 별 다른 영향을 미치지 않았으며, 후면 콘크리트의 탈락면적에는 큰 영향을 미치는 것으로 나타났다. 충격체의 충돌속도가 증가할수록 철근콘크리트 슬래브의 국부손상 정도는 증가하는 경향을 보였다. 이상의 해석결과는 격납건물 및 구조물의 내충격설계시 유용한 자료로 활용될 수 있을 것으로 기대된다.

In the present study, the water impact loads on two-dimensional symmetric and asymmetric wedges were mainly studied. The impact pressure and force were measured during a vertical drop of the symmetric and asymmetric wedges. The measured pressure was compared with analytic solutions. The measured force at a local area of the wedge was compared with the integrated pressures and analytic solutions. Some findings on symmetric and asymmetrical wedge drops are presented, and the reliability of the force sensor used for the measurement of the local impact force is discussed.

Purpose This study aims to analyse the impact of the development of fintech and the emergence of internet primary banks due to the increasing use of smartphones on the performance of traditional local banks from both financial and non-financial perspectives. Return on equity (ROE) and return on assets (ROA) are used to assess the performance differences between the two types of banks and how these differences are affected by their financial characteristics. Design/methodology/approach Using return on equity (ROE) and return on assets (ROA) as indicators, we identified the differences in operating performance between the two types of banks. In addition, this study analysed the impact of financial characteristics on profitability through regression analysis with various control variables. We further studied the impact of non-financial characteristics (customer reviews, social media reactions, etc.) on operating performance. Findings The net interest margin ratio of local banks had a positive impact, while the marketable securities ratio of Internet primary banks had a negative impact. The non-financial analysis shows that the number of customer reviews and social media reactions have a significant impact on the performance of Internet primary banks, suggesting that customer satisfaction and positive market perception are important factors in the performance of Internet primary banks.

To analyse the impact of recognition for local food on frequency of visiting for local food restaurants, we surveyed 333 residents in the Kyungsangdo areas. The findings are summarized as follows. On interest of native foods, 'much' scored 40.6% and 'taste' scored 32.9%, in requirement of development. The criteria of selection of local foods was 62.3% in 'taste'. 'Institute(municipal government)' scored 31.3% as the main responsible body for the succession of local foods. The most significant criterion for tourism product of local foods was 'taste'(34.5%). The most effective way to popularize the local foods was to 'hold various kinds of cultural events'(27.5%). The necessity score on tourism product of local foods was 3.55 points. The highest recognition on native local foods was 'succession to next generation'(3.96 points). The most influential variable affecting the visit frequency toward local food restaurants was 'health factor'.

High velocity impact of projectile generate local failure such as penetration, scabbing, perforation on concrete. It has been reported that local failure is affected by such as nose shape, mass of projectile. In this study, comparing and weighing the impact failure properties of concrete by high velocity impact test that using spherical nose and flat nose type projectile. As a result, It was considered that scabbing of Flat nose projectile reduced more than spherical nose projectile by dispersion of impact force.
