최근 고속도로 차선 위반으로 인한 교통사고 발생률이 증가하는 추세이다. 이러한 교통사고 비율의 감소를 위해 지정차로제와 다인승 전용차로제를 단속하는 법규가 존재하지만, 실질적인 단속 비율이 굉장히 낮아 유명무실한 법규로 작용하고 있으며 해당 법규 단속에 필요한 비용도 크게 발생하고 있다. 이러한 문제를 해결하기 위해 교통 법규의 효율적인 단속을 위한 저비용 고효율 단속시스템이 필요하다. 본 논문에서는 지정차로제 및 다인승 전용차로제의 효율적인 단속을 위한 인공지능 기반 차량 통합 단속시스템을 개발하고자 한다. 이를 위해 현재 시행 중인 지정차로제와 다인승 전용차로제의 교통법규 및 사고사례를 분석하고 적용하여 이에 적합한 교통법규 위반 단속 알고리즘을 설계하였다. 그리고 이를 통합한 교통단속 통합시스템의 설계 방안을 제시한다. 이를 통해 운전자의 교통 법규 위반 여부를 판별하고 웹서버를 구축하여 교통 법규 위반 여부를 판단하고 벌금을 부과하는 웹 기반의 교통단속 통합시스템을 제시하였다. Recently, the incidence of traffic accidents due to highway lane violations has been increasing. In order to reduce the rate of traffic accidents, there are laws that crack down on the designated lane system and the multi-seater exclusive lane system, but the actual crackdown rate is very low, acting as an ineffective law, and the cost of cracking down on the law is also high. In order to solve this problem, a low-cost, high-efficiency crackdown system is needed to efficiently crack down on traffic laws. In this paper, we would like to develop an artificial intelligence-based vehicle integrated crackdown system for efficient crackdown on designated lane systems and multi-seater lane systems. To this end, an appropriate traffic law violation control algorithm was designed by analyzing and applying traffic laws and accident cases of the designated lane system and multi-seater dedicated lane system currently in effect. It also presents a design plan for an integrated traffic control system that integrates it. Through this, a web-based integrated traffic control system was proposed to determine whether a driver violated traffic laws, establish a web server to determine whether he violated traffic laws, and impose fines.

제주 부동산업의 성장특성 분석

양영준(Young-Jun Yang) 한국콘텐츠학회 2020 한국콘텐츠학회논문지 Vol.20 No.5

2006년 제주특별자치도 출범 이후 여러 개발사업이 진행된 제주는 유입인구 증가 등의 영향으로 2011년 이후 여타 지역에 비해 부동산업이 성장하였다. 이러한 성장 이후에 2017년부터는 미분양주택 증가, 순유입인구 감소 등의 현상이 나타나고 있다. 본 연구에서는 2006년부터 2016년의 기간을 회복기(2006~2010년)와 확장기(2011~2016년)로 구분하여 변이할당분석과 성장률시차분석을 통해 제주 부동산업의 성장이 국가의 성장에 따른 영향인지, 지역의 산업구조와 경쟁력에 의한 것인지를 분석하였다. 분석결과 제주 부동산업의 매출액과 종사자수는 회복기에는 국가 성장의 영향에 의해 성장하였으나, 확장기에는 산업구조와 지역의 경쟁력에 의해 성장한 것으로 나타났다. 부동산업의 성장에 기여한 세부산업으로는 부동산 개발 및 공급업을 들 수 있으며, 경쟁력이 약화된 세부산업으로는 부동산관리업으로 나타났다. After the launch of Jeju Special Self-Governing Province in 2006, a number of real estate development projects were carried out; the real estate industry has relatively largely grown as compared with other regions since 2011. This growth has slowed down in 2017, along with the increase of unsold houses and the short of its incoming population, causing its real estate market recession. This study analyzed the source of real estate industry growth in Jeju: either affected by national growth power or its regional competitiveness. This study applied Shift-Share Analysis and Growth Differential Analysis, by dividing the recovery period (`06~`10) and expansion period (`11~`16). According to the result, sales amount and the number of employees in the real estate industry in Jeju had grown in the recovery period based on the national growth power. Its regional competitiveness and stable industrial structure grew in the growth period. Development and subdividing of real estate contributed to the growth of the real estate industry in Jeju. On the other hand, management of real estate weakened its market.

DiPasquale-Wheaton Four Quadrant Model(4QM) describes long term equilibrium in the real estate market under the division of the real estate market into two markets: the property market and the asset market. 4QM would be utilized as a decision-making tool for Seoul office investment and management, if we prove it is still reasonable for Seoul office market. Through the Granger`s casualty test under the 4QM hypothesis, it is proved that Seoul office rent level affects Seoul office price, and the latter affects the level of Seoul commercial construction. And the economic growth rate affects Seoul office rent level, and the market interest rate affects Seoul office price. As a result of proceeding impulse-response analysis and variance decomposition analysis with vector error correlation model, it proves that the impulse of Seoul office rent level has a positive effect on Seoul office price generally, and impulse of Seoul office price has a negative effect on the level of Seoul commercial construction contrary to 4QM. It also proves that the impulse of economic growth rate has a positive effect on Seoul office rent level, and the impulse of market interest rate has a negative effect on Seoul office price.
