  • A majority of car crash is affected by careless driving that causes extensive economic and social costs, as well as injuries and fatalities. Thus, the research of precise crash detection systems is very significant issues in automotive safety. A lot of crash detection algorithms have been developed, but the coverage of these algorithms has been limited to few scenarios. Road scenes and situations need to be considered in order to expand the scope of a collision detection system to include a variety of collision modes. The proposed algorithm effectively handles the x, y, and z axes of the sensor, while considering time and suggests a method suitable for various real worlds. To reduce nuisance and false crash detection events, the algorithm discriminated between driving mode and parking mode. The performance of the suggested algorithm was evaluated under various scenarios, and it successfully discriminated between driving and parking modes, and it adjusted crash detection events depending on the real scenario. The proposed algorithm is expected to efficiently manage the space and lifespan of the storage device by allowing the vehicle's black box system to store only necessary crash event's videos.

  • The purpose of this study is to examine the impact of perceived sustainability management fit of SPA brands on consumer purchase intention. A survey was conducted targeting women in their 20s and 30s from April 27th to May 6th 2013, and a total of 350 questionnaires were used in the final analysis. Frequency analysis, reliability analysis, factor analysis, ANOVA, simple regression analysis and multiple regression analysis were carried out using SPSS ver 21.0. The results of this study are as follows. First, fit of all three areas- economic, ecological and social-of sustainability management activities have a significant impact on consumer perception on sustainability activities. Second, perceived sustainability activities by SPA brands are found to have a positive effect on brand attitude, brand trust and consumer satisfaction. Third, brand attitude and consumer satisfaction forged by perceived sustainability activities by SPA brands have a positive impact on consumers' purchase intention. Based on the result of this study, the following marketing implications can be suggested. First, SPA brands need to be more active in all three area of sustainability activities while coming up with measures for differentiated social sustainability activities. Second, SPA brands need to meet their primary obligation by providing consumers with quality products at a reasonable price. Third, SPA brands need to recognize the potential value of sustainability activities as a driver of a longstanding relationship with consumers as well as long-term profit and value creation, leading to a great financial performance.

  • 민간투자사업은 30~40년이라는 긴 기간동안 수익이 발생하는 특성을 가지며 시간이 흐름에 따라 수익과 비용에 변동요인이 발생하여 통계모형이나 현금흐름할인법보다는 시간 흐름에 따른 변수들의 상호작용에 대한 시뮬레이션이 가능한 시스템 다이내믹스 기법을 이용한다면 내외부 변수들에 대해 유의미한 시뮬레이션 결과를 도출해 낼 수 있을 것으로 판단된다. 즉, 이전에 시도된 적 없는 항만분야 민간투자사업에 시스템다이내믹스를 기반으로 한 재무적 타당성 비교·검증 모형 수립을 통해 기존 현금흐름할인법과의 차이를 비교해보고, 거시경제요인, 운영기간, 사회적 할인율 등 각 변수들의 상호관계 작용이 재무성에 변화에 어떤 영향을 미치는지 시뮬레이션해 봄으로써 기존에 시도해 보지 않은 차별화된 연구를 수행해 보고자 한다.

  • In 2003, "The National Land Use and Planning Act" (NLUP Act) was enacted unifying two old laws; "The Urban Planning Act" enacted in 1962 and "The National Land Use and Management Act" enacted in 1972. One of main reasons of unifying two acts was to extend urban planning-based development systems to rural areas for preventing uncontrolled urban sprawl in rural areas and enhancing or settlling plan-based land use system in rural areas. This paper is conducted with the following specific objectives: i) to critically review the contents of NLUP Act in terms of rational rural land use planning; ii) to evaluate plan-based land use practices in rural area by NLUP Act; iii) to appraise performance level for prevention against unplanned development activities in rural areas by NLUP Act. To accomplish these objectives, we surveyed actural state of rural land use and development system by the new act in two case study areas. Ansung city in Gyeongi province as an urban sprawl region and Hamyang county in Gyeongnam Province as a remote rural area. Study results ascertained that the new act can not effectively control rural land use and not prevent over-use of agricultural land in the positive and effective ways because of followering three points.

  • Purpose: The study aims to assess the current status of domestic public food delivery apps and analyze the process through which sellers choose between private delivery apps and public delivery apps. This involves exploring strategiesto achieve the original purpose of public food delivery apps, which is to enhance the small business owners income and promote consumer welfare by preventing the monopoly of private food delivery apps. Research design, data and methodology: the research methodology is based on a model that introduces adjustments for non-economic effects, considering the preferences of multi-homing consumers, to more realistically reflect the benefits of sellers' choices. For data analysis, real business performance data from 'Daeguro', 'Meokkaebi', and 'Somunnan Shop' were used. Results: The study revealed that if the market share of public delivery apps within a specific region increases beyond a certain level, the benefits for small-business sellers also increase. This leads to the strategic advantage of simultaneously using both delivery apps. Furthermore, the results exhibit a tendency similar to real social phenomena. Conclusions: This analysis confirmed the role of public food delivery apps in the domestic delivery app market and presents policy recommendations, including application integration and the implementation of exclusive public interest functions, to effectively fulfill this role.

  • 사회간접자본(SOC)은 국가 산업부문과 국민경제에 매우 큰 영향을 끼치는 생산요소로 이에 대한 투자는 경제성장에 있어 필수적이며, 국가 경쟁력을 결정하는 주요 요소이다. 이러한 중요성을 인식하여 정부에서는 지난 1999년부터 예비타당성조사 제도를 도입하여 SOC 사업시행 유 무를 검토하고 있으나 과학적 투자평가방법의 미비, 조사 결과의 신뢰성 저하 등 근본적인 문제가 끊임없이 제기되고 있다. 이를 개선하고자 수행된 주요기관의 선행연구는 대부분 수요추정 및 경제성 분석 중심으로 진행되었고, 예비타당성조사의 주요 단계인 정책적 분석에 대한 연구진행은 아직 미흡한 실정이다. 이에 본 논문에서는 관련 학문과의 적절한 융합과 조화가 요구되는 (예비)타당성조사의 정책적 분석단계에 대하여 현행 전문가의 경험과 관련 자료에 의한 정성적 평가를 개선하고자 가치공학(VE)의 성능평가기법을 활용한 정량적 의사결정모델을 개발 제안하여 분석결과의 정량화를 유도하고 체계적 분석절차에 의한 전략적 판단도구로의 활용과 신규투자사업 목표에 대한 정책적 측면의 가치향상에 기여하고자 한다.

  • In spite of the fact that the food group(Food, Drinks and Health foods & Agricultural and Marine products) occupies little position in total sales of Internet shopping mall, the food group's sales in cyber shopping mall in 2006 have increased 678.1% over 5 years. In addition to the fact that the food consumption pattern has changed from quality-oriented to convenience, health and safety-oriented, the need to decrease the opportunity cost created by housework is rising in the context of increase of women's work participation rate. The wind of change like these will become the foundation on which cyber food industry will be developed. The factors having an effect on consumer purchasing intentions when one buy foods through internet shopping malls are researched in this thesis. For the investigation, women of 697 were surveyed by a questionnaire, and the data were analyzed by the SPSS for WINDOW(Version 12.0). The result is as follows: Factors having an effect on food purchasing intentions are Convenience(Timesaving, Troublesomeness), Customer service(Responsiveness, Reliability, Empathy, Tangibility), Perceived Customer Risk(Economic, Social, Performance risk) and Shopping experience(Easy to find out, Easy process for payment) in order.
