Uncertainty increases as a result of environment change and change of individual decision-making in extreme weather. This study consider individual decision-making which has been not covered until now. The purpose of this study is making Agent-Based Model to predict it more accurate that how much change travel demand in heavy rain and heavy snow. Through this model, it can be utilized to forecast travel demand, changes in travel behavior and traffic patterns. It will be also possible to predict discomfort index and risk of accidents.

현재 글로벌 환경은 빠르게 변화하는 4차 산업혁명의 도래로 산업구조는 물론 사회경제 전반에 걸쳐 거대한 변화에 직면하고 있으며, 미래에 대한 불확실성이 깊어져서 이에 대한 빠른 대응이 필요한 시대가 되었다. 또한 4차 산업의 주축인 디지털 혁명과 코로나 19 팬데믹 사태로 변화의 가속화가 진행되면서 이러한 변화에 얼마나 신속하게 대응하느냐가 생존과 성장의 핵심이 되었다. 본 연구는 기존의 선행 문헌연구를 바탕으로 기술기반 창업기업의 창업가 역량과 기업성과 간의 인과관계를 통합적으로 규명하는 것을 목적으로, 불확실한 경제 상황 속에서 기술창업과 창업가 역량의 중요성을 인식하여 기업성과에 영향을 주는 요소를 분석하고자 한다. 이와 같은 목적을 달성하기 위하여 창업가 역량을 독립변수로 하고, 정부지원활용을 매개로, 창업가 일반적 특성(업종, 업력, 창업경험, 특허보유, CTO인력보유 여부 등)을 조절변수로 하여 기업성과에 미치는 영향에 대한 연구모형을 설정하였다. 연구모형 검증을 위해 대전 대구 지역의 연구개발특구, 산업기술단지, 첨단산업단지, 창업보육센터, 테크노파크등, 기술집접화시설에 입주해 있는 217개 기업을 대상으로 온 오프라인 방식의 설문조사를 실시하였다.

본 연구의 목적은 한국의 글로벌에 따른 유명상표와 지적재산권의 관계를 살펴보고, 위조상품을 상표권적 측면과 국제통상문제의 시각에서 조망한 후 이에 따른 대응 방안을 제시하고자 한다. 연구방법은 문헌조사와 전문가 인터뷰를 실시하였다. 문헌 조사는 국내외 각종 문헌과 정부 자료 및 관련 법제에 대해 수집, 분석하였으며, 전문가 인터뷰는 관련 업체, 관련 분야 전문가를 중심으로 진행되었다. 연구 결과 첫째, 우리 정부는 공정한 경쟁 조건과 공통의 규칙 아래서 세계 경쟁을 펼치기 위해서 관련법제를 지속적으로 정비하고 둘째, 위조상품 추방을 위해서 제도의 실효성을 확보할 수 있도록 효율적이고, 강력한 법 집행이 선행되어야 하며 셋째. 유명상표와 관련한 타인의 신용에 편승하거나 부적절한 표현 등을 사용해서 품질과 관련하여 소비자를 현혹함으로써 부당한 이득을 얻으려는 상표 질서 문란 행위자를 견제하여 부정경쟁을 예방, 억제하는 방향으로 상표법이 운영되어야 하며 넷째. 시장에서 위조상품의 폐해가 어떠한 결과를 가져오는지 업계 및 일반인들에게 깊이 인식시켜야 하는 것으로 나타났다

국내외적으로 전자상거래 이용이 활성화됨에 따라 물류환경도 변화하고 있다. 또한 전자상거래 시대에 부합하는 물류서비스 경쟁도 가속화되고 있다. 업무환경이 현장에서 단순 반복 업무로 이뤄진다는 Logistics의 특성상 차별화 된 서비스를 위해 Mobile 기기를 도입한다는 것은 필수적인 추세가 되어 가고 있다. m-Logistics의 확산은 이제 시대의 흐름이되었으며, 따라서 모바일 환경에 대한 효과적인 대응전략은 기업의 수익과 비용감소에 직접적인 역할을 할 것이다. 물론 물류분야에 Mobile을 도입하여 그 효과를 최대화하기 위해서는 물류업무의 표준화, 모바일 기기의 기능강화, 무선통신 인프라의 확충, 기업투자비 경감등의 조건을 해결해야 한다는 선행과제가 있지만, 공차 운행으로 인한 물류비 절감과 유무선 통합 물류관리를 통한 업무 생산성 및 고객서비스 개선이라는 기대효과는 Mobile의 도입을 충분히 매력적으로 보이게 하는 요소인 것이다 이런 점에서 본 논문에서 제시하는m-Logistics환경에서 물류 서비스 중 가장 중요한 전자지불과 거래보안 서비스를 새롭게 제시하였다.

최근 대형고층건축물의 수적증가로 인해 화재 발생 시 재실자의 피난안전 확보가 매우 중요하게 되었다. 특히 지속적인 증가를 보이고 있는 고령자는 화재발생시 피난 및 대응이 부족해 많은 피해가 예상되기에 고층건축물의 피난계획 및 설계 시부터 재해약자인 고령자의 피난안전성 확보가 우선시 되어야한다. 이를 위해서는 고령자의 피난행동특성에 대한 연구 및 실험을 통한 기초적인 피난Data구축이 선행 되어야하기에 본 연구는 고령자를 대상으로 초고층건물의 상향과 하양의 이동피난실험을 진행했으면 노인들의 체력수준, 공간인지 수준, 화재발생시 피난 선호 방식 등에 대한 의견을 수렴하고자 피난실험 전과 후로 구분하여 설문을 실시 분석하였다.

Purpose: To identify the epidemiological characteristics and risk factors of coronavirus disease 19 (COVID-19) outbreaks depending on the type of educational facility by analyzing the COVID-19 cluster associated with educational facilities. Methods: This study is based on epidemiological investigation of COVID-19 cluster in Gangwon-do, Korea from December 10, 2020 to September 23, 2021 reported to the Korea Disease Control and Prevention Agency's Integrated Disease and Health Management System. Four hundred seven patients in 19 facilities, classified as cluster related to educational facilities, were the study population. The result of preliminary epidemiology survey report, in-depth epidemiological survey by phone and the result of risk assessment derived from the field epidemiology investigation were retrospectively analyzed to evaluate infectivity and the characteristics of the risk factors. Results: There were total of 407 confirmed patients related to 19 educational facilities, with 204 students under the age of 19 (50.1%). One hundred fifty-five preceding spreaders were from families (38.1%) and 125 were the teachers (30.7%). The place exposed to confirmed patients was the highest with 139 people (34.2%) at home. Conclusions: It was confirmed that the cause of the occurrence of clusters related to educational facilities was higher due to family transmission than the risk of facilities in schools. Nevertheless, continuous efforts should be made to control infection in educational facilities, and that teachers' implementation of principles for prevention of COVID-19 personal hygiene in their daily lives should be strengthened.

Two experiments were performed to investigate effects of background depth information on the judgment of two-dimensional shapes, using the Posner et al.'s(1969) physical match task. In both experiments, the focus was on whether the background depth information affects the decisions of physical shape sameness of two letters or figures presented successively. In Experiment 1, artificially constructed rues of linear perspective and texture gradient were used, whereas cues contained in a real road situation were used in Experiment 2. The results of both experiments showed that the depth cues affect the perception of two-dimensional shapes. That is, when two stimuli of the same physical shape were likely to be perceived differently due to the given depth cues, response accuracies('yet' in this case) decreased and reaction tines of physical match increased. And when two stimuli of the different physical shape were likely to be perceived the same due to the given depth cues, response accuracies('no' in this case) decreased and reaction times of physical match increased likewise. These results wert discussed in terms of some conceptual methodological problems of the previous studies on the shape constancy and the directions of future research.

Recently, a lot of effort has been made to reinforce the profitability of the company through successful overseas expansion as one of the major ways to secure the competitiveness and to increase the business value these days. So, this study aims to try to analyse of the status of the overseas expansion case for the recent power industry through the case of the Korea Western Power Co., Ltd. as a measure of the management efficiency strategy of the public sector organization, and to present the policy implications about the management efficiency in the future by drawing upon the management efficiency strategy. This paper suggests alternatives as follows: First, the competitiveness should be reinforced through continuous change and innovation and the management efficiency should be developed. Second, the governance system for public-private sector should be constructed. Third, the efficient management of the global human resources is needed. Fourth, the mutual confidence-building through the active contribution to the community activities is required.

This research is about local impacts of concentrated social disadvantage in a specific urban district, and is discussing these issues by focusing on previous research from Western countries. Further, by analyzing the results of a field survey conducted in this district, I am clarifying the reality of socially disadvantaged areas and the needs of their residents, while seeking results supporting a theory of inclusive area revitalization. With this survey I could verify that the aging of local residents and the concentration of low-income population is increasing, and in this district an unbalanced community mix is becoming apparent. Currently, insecurities concerning economic and health aspects are the most serious issues. In response to the residents' needs counseling on housing issues and social services, that become necessary with advancing age, like health services or housing support, are increasingly required. Since today laws for antidiscrimination (namely, Dowa) measures are outdated it is necessary to establish a community based approach or a neighborhood based governance model, in addition to the existing public support, as response to these local challenges and needs.

In this study, an imputation model using circular probability distribution was developed in order to overcome problems of missing data from a traffic survey. The existing ad-hoc or heuristic, model-based and algorithm-based imputation techniques were reviewed through previous studies, and then their limitations for imputing missing traffic volume data were revealed. The statistical computing language 'R' was employed for model construction, and a mixture of von Mises probability distribution, which is classified as symmetric, and unimodal circular probability were finally fitted on the basis of traffic volume data at survey stations in urban and rural areas, respectively. The circular probability distribution model largely proved to outperform a dummy variable regression model in regards to various evaluation conditions. It turned out that circular probability distribution models depict circularity of hourly volumes well and are very cost-effective and robust to changes in missing mechanisms.
