최근 시스템 개발 환경이 싱글프로세서 기반의 환경에서 멀티프로세서 기반의 환경으로 변화됨에 따라 개발된 시스템 프로그램들이 멀티프로세서 기반과 싱글프로세서 기반에서 호환이 가능하도록 설계 및 구현의 중요성이 부각되고 있다. 특히, 실시간성이 중요시 되는 내장형 소프트웨어 분야 및 측정 장비와 같이 정밀성을 요구하는 분야의 경우 멀티프로세서 기반의 실시간성을 제공하기 위한 연구가 필요하다. 운영체제에 종속적인 실시간성은 운영체제에 따라 지원여부를 결정하는데, 범용 운영체제인 윈도우즈의 경우 실시간성을 지원하기 위해 RTX나 INtime과 같은 고가의 서드파티를 사용해야 한다. 그러나 서드파티를 사용함으로써 제품 개발 시 고가의 구입비용 및 유지보수 비용으로 인한 개발 비용의 증가를 초래하는 문제점이 발생한다. 이러한 문제점을 해결하기 위해서, 본 논문에서는 멀티프로세서 기반의 윈도우즈에 실시간성을 제공하기 위해 x86 아키텍처의 Local APIC를 이용하여 윈도우즈에 실시간성을 제공하는 RTiK-MP(Real-Time implant Kernel-Multi Processor)를 설계 및 구현하였고, RTiK-MP의 성능 검증 및 평가를 위하여 휴대용 점검장비를 이용한 성능 측정 결과를 분석한다. As the system development environment moves from single core to multi core-based platforms, it becomes more important to maintain compatibility between single core-based implementations and multi core-based implementations. Moreover, it is very important to support real-time on multi core platforms especially in cases of embedded software or test equipments which need real-time as well as correctness. Since Windows operating system dopes not support real-time in itself, it has been supporting real-time using expensive third-party solutions such as RTX or INtime. So as to reduce this kind of development expenses, in this paper, we propose RTiK-MP(Real-Time implant Kernel-Multi Processor) which supports real-time on Windows using the Local APIC of x86 architectures, and evaluate the performance of the proposed RTiK-MP after deploying it on portable missile test equipments.

송창해(Chang-Hae Song),도현욱(Hyun-Wook Do) 한국외식경영학회 2023 외식경영연구 Vol.26 No.5

본 연구는 식품 주구매자의 식생활 역량에 초점을 맞춰 김치 구매율과 어떠한 영향관계를 맺고 있는지, 또한 품질민감도가 매개효과를 갖는지 분석하였다. 그 결과 첫째, 식생활 역량의 3가지 하위 요인인 건강한 식생활 역량, 안전한 식생활 역량, 전통 식생활 역량은 모두 김치 구매율에 유의한 영향을 미쳤다. 이 중 건강한 식생활 역량과 전통 식생활 역량은 부(-)적 영향을 미쳤고, 안전한 식생활 역량은 정(+)적 영향을 미쳤다. 둘째, 식생활 역량의 3가지 하위 요인과 김치 구매율 간 관계에서 품질민감도의 매개효과는 모두 유의하게 나타났다. 결론적으로 식품 주구매자의 식생활 역량은 김치 구매율에 영향을 미치고, 품질민감도의 매개효과도 영향을 미치는 것으로 나타났다. This study focused on the dietary life competency of the main food purchaser and analyzed the relationship between the purchase rate of kimchi and the mediating effect of quality sensitivity. As a result, first, the three sub-factors of dietary competency, healthy eating, safe eating, and traditional eating, all had a significant effect on the kimchi purchase rate. Among them, healthy eating competencies and traditional eating competencies had a negative (-) effect, and safe eating habits had a positive (+) effect. Second, the mediating effect of quality sensitivity was found to be significant in the relationship between the three sub-factors of dietary life competency and the kimchi purchase rate. In conclusion, it was found that the dietary life competency of the main food purchaser affected the kimchi purchase rate, and the mediating effect of quality sensitivity also affected.

실시간성(Real-Time)이란 정확한 주기에 정확한 결과 값의 반환, 혹은 일정한 주기마다 정해진 일을 수행하는 것으로써, 내장형 소프트웨어 분야에서 갖추어야할 가장 중요한 요건이다. 최근 이러한 내장형 시스템의 사양이 싱글프로세서에서 멀티프로세서로 변화됨에 따라 멀티프로세서 상에서의 실시간성을 제공하기 위한 연구가 중요시 되고 있다. 실시간성은 운영체제에 종속적으로 운영체제에 따라 제공여부가 결정되는데, 범용 운영체제인 리눅스의 경우 운영체제에 패치(Patch)를 통해 실시간성을 제공하고 있다. 그러나 다른 범용 운영체제인 윈도우즈의 경우 고가의 구입비용을 가지는 서드파티를 구매하여 실시간성을 제공해야한다. 이에 따라 실시간성을 제공하는 윈도우즈 기반의 제품을 개발 시 개발 비용의 증가를 초래하는 문제점이 발생한다. 따라서 이러한 문제점을 해결하기 위해 범용 운영체제인 멀티프로세서 기반의 윈도우즈 XP 환경에서 실시간성을 제공하기 위한 연구가 필요하다.

Cricopharyngeal dysphagia(CPD), a common condition in the dysphagic patient, refers to the dysfunction of the upper esophageal sphincter complex(UESC), which is composed of the cricopharyngeus, inferior pharyngeal constrictor and the upper segment of the cervical esophagus. Primary CPD is the disease entity solely confined to dysfunctional UESC, while secondary CPD encompasses various conditions that accompany UESC dysfunction. For proper diagnosis and treatment of such entity, a thorough understanding of the complex anatomy and physiology of the upper esophageal sphincter. Adequate relaxation of the cricopharyngeal muscle in conjunction with anterosuperior excursion of the larynx by suprahyoid muscles and propulsion of food bolus are prerequisite for normal swallow, mechanisms of which if altered result in cricopharyngeal dysfunction. Of the various methods used for the diagnosis of cricopharyngeal dysphagia, videofluoroscopy remains the method of choice. Mechanical dilatation of the cricopharayngeus, cricopharyngeal myotomy and botulinum toxin injection and head-lift exercise have been used in clinical practice to relieve dysphagia in such patients. Such procedures have therapeutic effect in primary CPD, but so often fail to relieve swallowing dysfunction in patient with secondary CPD. We herein explain ancillary procedures that support these primary treatment options, which lead to successful treatment of dysphagia.

첨단 군사 체계를 위한 측정 장치의 필요성에 따라 낮은 지연을 추구하는 실시간 특성인 시간 결정성과 수행의 정확성은 매우 중요해 졌으며, 이러한 이유로 리눅스와 같은 범용 운영체제에 실시간 기능을 추가하는 시장 요구가 증대하게 되었다. 따라서 RTLinux와 RTAI가 리눅스기반의 이중 커널로 개발되었다. RT-Linux의 경우 경성 실시간성을 제공하지만 어셈블러를 사용해야함으로 개발자가 다루기 어려운 단점이 존재한다. 또한 RTAI의 경우 연성 실시간성만을 제공하는 단점이 있다. 이러한 단점을 해결하기위해 RTiK-Linux를 개발하였다. 본 논문에서는 리눅스에 경성 실시간 특징을 가지며 새로운 이중 커널 구조인 실시간 이식 커널인 RTiK-Linux를 제안한다. 먼저 관련 연구에 대한 소개를 하고, 타이머 설정 값과 거의 일치하는 분해능을 보장하는 설계 방법론을 기술한다. 그리고 경험적 측정으로 얻어진 결과를 보이고, 제안 하는 RTiK-Linux를 검증 및 평가하기 위하여 그 결과를 분석한다. According to the necessity of measuring equipments for advanced military systems, real-time characteristics such as time determinism and execution accuracy pursuing low-latencies have become very important. With this reason, the market demand for real-time features in the general purpose operating system such as Linux has been enlarging. To meet these requirements, RTLinux and RTAI has been developed as dual-kernels based on Linux. However, developers should use assembler languages to facilitate real-time in RT-Linux, it is very difficult to deal with it. RTAI has disadvantage that it only provides soft real-time. To solve these problems, RTiK-Linux was developed. In this paper, we propose a new dual-kernel with hard real-time capabilities in Linux, called RTiK-Linux(Real-Time implemented Kernel for Linux). We first introduce related researches and then describe the design methodologies to guarantee the resolution which almost accords with the timer settings. Finally, we present the results of experimental measurements and analyze them in order to validate and evaluate the proposed RTiK-Linux.
