This paper describes the design and implementation of HNCP bundle in the OSGi framework targeted to the home network system. The developed home network system is composed of a home server and several networked home appliances, and is connected via residential gateway to the external access network. The developed HNCP bundle allows a user to control and monitor home appliances in HNCP domain. We show the feasibility of the implemented HNCP bundle in the OSGi framework.

본 논문에서는 단상 영구자석 전동기를 초고속으로 구동하면서 전력을 제어할 수 있는 방법을 제안한다. 일반적으로 단상 영구자석 전동기의 제어는 전류 센서 및 홀 위치 센서를 기반으로 전류 제어를 통하여 이루어진다. 그러나 초고속 구동에서 위치 측정의 정밀도는 떨어지게 되고, 평균 전류의 측정 또한 어렵게 된다. 또한, 가정용 단상 전원을 사용하는 경우, 전류 고조파 규제를 만족시키기 위하여 PFC회로의 추가가 필요하다. 본 논문에서는 하나의 홀 센서를 사용하여 위치를 추정하고, 전류 센서를 사용하지 않으면서 전류 고조파를 억제할 수 있는 초고속 구동 방법을 제안한다.

Etiology of temporomandibular disorders is multifactorial origin and complex. therefore, reversible and conservative treatment is recommended in the initial approach of TMD. oral appliances are widely used to manage TMDs, while their mechanisms of action and its effects remain controversial and unclear. The purpose of this paper was to review information regarding the types, designs, and materials of occlusal appliances and the rationale for the continued use of OS for the management of TMDs.

Internal heat given off by human beings, lightings and domestic appliances is an Important factor which must be taken Into account estimate of building heating loads. This study outlines the procedures for determining the internal heat from these source and calculates the amount of internal heat added to an heat Ing spaces. This investigation shows that a family of four has a typical hourly internal heat production which averages approximately 460 Kilo- calories an hour in our country.
