Q+P Esto는 정보가전용 RTOS인 Q+P를 위한 원격 개발 환경이다. 타겟에이전트는 타겟에서 실행되면서 호스트에 있는 디버거와 원격쉘, 그리고 자원모니터 같은 Q+P Esto 도구들이 원격 개발을 하는데 필요한 기본적인 기능들을 제공한다. 본 논문은 GNU gdb 5.0에 있는 gdbserver를 이용하여 타겟에서 실행 중인 응용 프로세스를 감시 및 제어하는 구조를 제안한다. 디버깅을 위하여 정지점(breakpoint)에 걸린 응용 프로세스를 continue 시켰을 때 응용 프로세스가 무한 루프에 빠지더라도 타겟에이전트는 다른 도구의 요청을 계속 처리할 수 있다. 응용 프로세스를 제어하는 자세한 메커니즘은 gdbserver가 담당한다. 따라서, 타겟에이전트는 단지 gdb remote protocol만 사용하여 gdbserver와 통신하면 되므로 구현이 용이하다.

In recent years, the numbers of the orthodontic dental patients have been rapidly increased in adolescent or young adult aged generation. It has been well known that it would be very hard to control the oral hygiene cares for orthodontic applied dental patient because of the complexity of the appliance. So the caries prevalence of the orthodontic dental patients would be higher than non-appliance persons, and it might be easy to cause the dental caries especially on the labial or buccal surface of the tooth through equipping the fixed type appliance with a long period, even though the alignment of the teeth would be arranged well. So, the massive preventive program for preventive dentistry should be needed for the dental patients for orthodontic treatment, in order to protect the dental caries and the periodontal disease for them. But, lots of the dentists or dental hygienists sometimes neglect of this point for preventive dental cares orthodontic dental patients, or do not know the importance and how to manage the skill for the preventive dental works in clinical. In this article, it will be introduced the basic theories and skills for preventive cares as tooth-brushing instruction, fluoride topical application and pit and fissure sealant, scaling and professional mechanical tooth cleansing and the diet control, for the dental patients with the fixed type of the orthodontic appliance, in case by case.

As the Hydrogen law was enacted, 4 types of hydrogen appliances were designated as inspection products. The types of hydrogen appliances are water electrolysis equipment, hydrogen extraction equipment, stationary fuel cells, and mobile fuel cells. The establishment fo safety standards for hydrogen appliance inspection defines risk factors for each hydrogen appliance and stipulates safety standards to prevent risk factors. The main safety standards for each hydrogen appliance are hydrogen quality and safety control for water electrolysis, toxic substances emission prevention and carbon monoxide emission prevention for hydrogen extraction facilities, vibration safety for mobile fuel cells.

Occlusal stabilization appliance is one of the most common treatment option for management of temporomandibular disorders. It acts in oral cavity for several hours per day, and usually it will take at least 6 months to 2 years of total wearing periods to take a treatment goal. In the oral cavity, occlusal stabilization appliance, unintentional manner, is able to acts as a reservoir of bacteria and protect bacteria from saliva and oxygen. This condition is so favorable to many bacteria such as S. mutans and other anaerobes, usually have been reported as causative factors of dental caries, periodontal disease and oral malodor. In this study, we investigated anaerobic bacteria and S. mutans count before and after occlusal stabilization appliance use to evaluate the possible role of occlusal stabilization appliance as protector of these bacteria. Four men(average 27.5 years) wore maxillary occlusal stabilization appliance at each night(average 9 hours) for 5 days. we swabbed saliva-plaque mixed sample at 3 different site(maxillary left 2nd molar, maxillary left central incisor, mandibular left 2nd molar) before and after occlusal stabilization appliance use. Each samples were plated in (1) anaerobic blood agar medium, (2) selective S. mutans medium(MS-MUTV) and incubated in anaerobic chamber($CO^2$ 10%, $37^{\circ}C$) for 72 hours. Each bacterial colony forming unit(CFU) were counted with naked eyes. From obtained data, we can conclude as follows: 1. There was some changes about anaerobic bacteria and S. mutans count in oral cavity after occlusal stabilization appliance use. 2. The number of anaerobic bacteria was significantly increased at maxillary 2nd molar(P=0.003), maxillary central incisor(P=0.020) after occlusal stabilization appliance use compared with before. 3. Occlusal stabilization appliance use itself had indirect effect to increase the number of anaerobic bacteria at other uncovered opponent tooth site. 4. The number of S. mutans was significantly increased at maxillary 2nd molar(P=0.043), maxillary central incisor (P=0.049) after occlusal stabilization appliance use compared with before. 5. Occlusal stabilization appliance use itself had not any effect on the number of S. mutans at other uncovered opponent tooth site.

To date, induction motors have mainly been used for heating, ventilation, and air conditioning (HVAC) applications, however, there is significant research being done world-wide on the use of switched reluctance motor(SRM) in household home appliances. This papers proposes three phase SRM for the air-conditioner blower that has cost merit and good performance respectively compared with conventional induction motor.

Recently, we are living in environment which various electrical appliance help our life. But the meanwhile, we had not researched how far the electromagnetic waves of electrical appliance affected the human's life. In accordance with, this paper will find out how far the human are weighed with electromagnetic waves of electrical appliance. And we will demonstrate the method that humans are failed under minimum effect from the harmful electromagnetic waves.

There are microwave hyperthermia, microwave surgical knife, and microwave tissue coagulator etc. as the cure-appliance using microwave. The object of this paper is to develope the multipurpose cure-appliance which has the functions that can be used intestinal tumor as well as the existing superficial tumor. And this also have the function of surgical knife and tissue coagulator with endoscope. And then ascertain its functions through the experiments, and to suggest the direction for reserch hereafter.

In patients with moderate crowding, the use of Pendulum appliance can be considered as one of intra-arch appliances. Its resolves the crowding by moving molars distally in the maxillary arch. The most important advantage of Pendulum appliance does not require patient cooperation at all. In this case we used a Pendulum appliane to resolve anterior crowding with a single-arch treatment in the maxillary arch.
