자동차 운전자는 자신의 안전을 위해 항상 차량의 상태를 점검하여 차량의 상태를 파악하는 것이 필수이다. 만약 운전자가 차량의 상태를 알고자 한다면 전문 업체에게 의뢰하기 때문에 운전자는 많은 시간과 금전적 비용이 지불되어야 한다. 현재 IT의 발달로 인해 스마트폰의 다양한 기능을 이용하여 차량의 상태를 점검 할 수 있게 되었다. 그렇지만 기존의 스마트폰 자동차 진단 시스템은 자동차의 전문적인 지식이 학습해야 차량 상태를 알 수 있는 상태라 사용자들에게 진단기의 필요성이 부각되지 않는다. 이러한 불편한 점을 반영하여 스마트폰을 이용해 사용자들이 손쉽게 사용할 수 있으면서 자신의 차량 상태를 한 번에 파악할 수 있는 시스템이 요구된다. 본 논문에서는 OBD-II 프로토콜 변환 블루투스 커넥터를 통해 받아오는 OBD-II 정보를 이용해 자동차 운전자에게 필요한 차량 소모품 교체 주기의 점검, 차량 문제점 진단, 그리고 에코 드라이빙 판단 정보를 사용자에게 실시간으로 보여주며 손쉽게 사용할 수 있는 자동차 진단 시스템을 안드로이드 기반 스마트폰에서 구현 하였다.

Since 2016 when the regulations related to vehicle structure and device modification were drastically revised, the car tuning market has been growing rapidly. Particularly, many drivers are showing interest in changing the interior and exterior according to their preference, or improving the specifications of their cars by changing the engine and powertrain, among others. Also, as the initial engine settings such as horse power and torque of the vehicle are made for stable driving of the vehicle, it is possible to change the engine performance, via Engine Control Unit (ECU) mapping, to the driver's preference. However, traditionally, ECU mapping could be only performed by professional car engineers and the settings were also decided by them. Therefore, this study proposed a system that collects data related to the driver's driving habits for a certain period and sends them to a cloud server in order to analyze them and recommend ECU mapping values. The traditional mapping method only aimed to improve the car's performance and, therefore, if the changes were not compatible with the driver's driving habits, could cause problems such as incomplete combustion or low fuel efficiency. However, the proposed system allows drivers to set legally permitted ECU mapping based on analysis of their driving habits, and, therefore, different drivers can set it differently according to the vehicle specifications and driving habits. As a result, the system can optimize the car performance by improving output, fuel efficiency, etc. within the range that is legally permitted.

자동차에 대한 사용자의 욕구 다양화와 개성화가 '차량 꾸미기'로 표출되는 현상이 심화되고, 그에 따른 디자인 측면의 질적 저하와 성능과 기능 측면에서의 안정성에 우려가 발생되고 있다. 한국에 있어서의 튜닝은 관련 법규 및 전문 업의 미비상태와 무절제한 튜니으올 인해 전체적인 조형성과 기능적인 측면이 무시된 덧 대기식 작업이라는 지적과 함께 사회적 문제까지 비화되고 있는 현실이다. 본 연구에서는 커스터마이징을 도입하여 드레스업 용품과 다양한 튜닝 부품을 개발하여 고객 만족에 접근하고 있는 해외 양산 차 메이커와 전문 튜너(tuner)들을 중심으로 튜닝 사례와 드레스 업 용품 류를 차량의 부위별로 고찰해 보았다. 향후 자동차 스타일링의 방향설정에 있어서의 과제는 일반 소비자의 의식이 개인의 특성이 강조된 코디네이션에 대한 개념추구가 더욱 심화될 것이며, 라이프 스타일에 보다 밀착된 형태로의 소비자 니즈의 세련 화는 한층 진전될 것이다. 그 동안 국내 자동차시장의 소비자는 제품디자인을 생사자 중심에서 제시된 틀 안에서 수용하여 왔으나, 생산구조, 사회구조, 산업형태의 변화와 그에 따른 디자인 행위 그리고 디자인 가치의 변화를 초래할 것이다. 그에 따라 메이커와 디자이너는 이러한 환경 구조의 전환을 인지하고 또 다른 가능성을 모색하는 관계로써 상품 이면에 내재한 사회 문화적 의미, 즉 기호의 생산과 소비에 대해 진지하게 성찰할 필요가 있으리라 사료된다.

Information Technology (IT) and the internet have been major drivers the changes in all aspects of the business processes and activities. They have brought major changes to the financial statements audit environment as well, which in turn has required modifications in audit procedures. There exist, however, certain difficulties with current audit procedures especially for the assessment of the level of control risk. This assessment is primarily based on the auditors' professional judgment and experiences, not based on the objective hies or criteria. To overcome these difficulties, this paper proposes a prototype decision support model named CRAS-CBR using case based reasoning (CBR) to support auditors in making their professional judgment on the assessment of the level of control risk of the general accounting system in the manufacturing industry. To validate the performance, we compare our proposed model with benchmark performances in terms of classification accuracy for the level of control risk. Our experimental results showed CRAS-CBR outperforms a statistical model (MDA) and staff auditor performance in average hit ratio.

우리나라는 2000년 고령화 사회에 진입한 이후 2019년 현재 고령사회로 분류되고 있다. 이에 따라 고령선원의 수는 해를 거듭할수록 증가하는 추세이고, 고령선원의 해양사고 건수도 해마다 증가하고 있다. 도로 교통분야에서도 운전자의 고령화가 해운분야와 동일하게 나타나고 있다. 하지만, 도로 교통분야에서는 이러한 문제를 해결하려는 연구와 정책 등이 해운분야에 비해 활발하게 진행되었다. 이에 본 연구에서는 도로 교통분야에서 고령운전자에 의한 교통사고 발생원인을 줄이기 위한 노력 중 교육분야에 한정하여 살펴보고 이를 해기교육에 벤치마킹하였다. 국내·외 도로 교통분야에서는 인적요인 등의 발생원인을 줄이기 위한 방안의 하나로 고령운전자 교통안전교육을 시행하고 있다. 고령화에 따른 교육분야 문제 현황을 분석하고 도로 교통분야의 해결방안과 접목하였으며, 그에 따른 해기교육 개선방안은 다음과 같다. 첫째, 전문적인 면허취득교육을 시행하는 방안이다. 둘째, 고령선원의 면허갱신 시 직무 보수교육을 시행하는 방안이다. 마지막으로 고령선원 연령전환 교육을 시행하는 방안이다. 다만, 본 연구는 선원고령화에 따른 해기교육분야의 개선방안에 한정된 연구인 만큼 향후 다양한 분야에서의 연구가 필요할 것으로 판단된다.

The data was collected from the public health center, which was operated for one year, 1997. This case is evaluated and reoriented according to five elements of public health care system; system of resources for public health, organization and administration, health care delivery system of financing, management. In resources for public health, available health personnels are 15 physicians, 17 nurses, 11 nurse aides and 2 other persons. One professional health personnel take care of 609 clients, The equipments used for elderly and the disabled are 6 wheelchairs, 4 walkers, 1 hairwashers and 30 viberations. But these equipments are not enough to deal all clients. In organization and administration, planning and setting goals for community home care are made by the director, supervisor of family department and public health nurse. So there is no regular commitee for home care services in this community. The form of delivery of health care is focused on preventive health care. The important works of public health nurse are health education, preventive care for hypertension, D.M. and vaccination of communicable desease. In finaning system, funds come from central government(8.3%), local goverment(16.7%) and health center itself(3.8%), The services consist of health education, vaccination, clinical test and equipment. There are several local volunteers, which are local hospitals, a college, a christian association, a catholic association, a drivers association and a disabled association. The volunteer groups give physical and mental support to the clients. In management, this health center has three evaluation methods. One is done by local government, one is done by health center itself, and the other is done by clients with questionair. But the evaluation tools are deferent between agency. Home care services must be planned and evaluated. This public health center has to have more personnel, equipments, education for professional kowledge and meetings with community volunteer agencies.

Purpose: This study was aimed to examine the prevalence of metabolic syndrome (MetS) and cardiovascular risk factors among workers at small-sized companies having fewer than 50employees in Korea. Methods: A descriptive cross-sectional study was conducted using a secondary data analysis on workers' health examination data. Data from 21,784 employed workers were analyzed, including 16,488 males (mean age 38.7years)and 5,296 females (mean age 40.5 years). Participants were newly enrolled in annual health check-ups at a professional health clinic from 2009 to 2011. Logistic regression analysis was performed to identify age-adjusted gender specific predicting factors of MetS incidence. Results: The prevalence of MetS was 13.4% in male and 7.7% in female workers. Logistic regression analysis showed that, when age was adjusted for, family history of cardiovascular disease (CVD) was a predicting factor in both male and female workers. For male workers, heavy alcohol drinking and non-manual occupation (office workers/drivers) predicted MetS. Conclusion: Health care providers should screen for MetS periodically in small work places especially for those with a family history of CVD. Educational counseling needs to be given to male workers with sedentary occupations with an aim to reduce heavy drinking and encourage lifestyle modification.
