In this paper, a wind speed & direction module and the DSP(Digital Signal Processor) sensor interface circuit board are proposed. This DSP system accepts and process the informations from a wind speed & direction module, the atmospheric pressure sensor, the ambient air temperature sensor and transfers it to the PC monitering system. Especially, a wind speed & direction module and a DSP hardware are directly designed and applied. A wind speed & direction module have a construction that it have four film type RTD(Resistive Temperature Detectors) or film type Piezo sensors adhered around the circular metal body for obtaining vector informations about wind. By this structure, the module is enabled precise measurement having a robustness about vibration, humidity, corrosion. A sensor signal processing circuit is using TMS320F2812 TI(Texas Instrument) Corporation high speed DSP.

아건강상태(亞健康狀態)에 처하여 있는 환자는 양의학적으로 뚜렷한 병리적 변화를 찾아보기가 쉽지 않다. 그러나 중의학의 병기이론을 근거로 하면 아건강상태(亞健康狀態)는 일정한 병리적 상태에 처한 것으로 인식된다. 즉 인체의 음양과 기혈이 편파(偏頗)되어 있으며 단지 그 변화가 초기단계에 있기 때문에 병태(病態)적 요인에 비하여 정도(程度)적인 차이가 있는 것으로 인식된다. 중의학이 건강에 대한 인식은 ‘천인상응(天人相應)’과 ‘음평양비(陰平陽秘)’, ‘정신내치(精神乃治)’란 관념이다. 주로 사람과 자연환경 및 외부사회간의 상호관계, 그리고 체내의 음양조화를 이룬 동태평형(動態平衝)을 중요시한다. 즉 인체의 기혈평형과 장부기능의 협조(協調)를 강조하고 기기(氣機)의 조창(調暢)이 건강의 근본(根本)이라고 인식한다. 시대적인 관계로 중의학에는 아건강상태(亞健康狀態)란 용어가 없지만 2000여년 전(前)에 성서(成書)된 중의학의 경전거작(經典巨作)인 ${\ulcorner}$내경(內經)${\lrcorner}$ 속에 일찍이 ‘미병(未病)’이란 개념(槪念)과 치미병(治未病)의 관념을 제출하였다. 이는 중의학이 미병선방(未病先防)의 의학사상을 나타내었고 주로 치병지미성(治病之未成), ‘치기미전(治其未傳)’, ‘차후방복’등 세 가지 방면의 내용을 제시된다. 또한 중의학은 양생학(養生學)에 대하여 특별히 중시하였고,${\ulcorner}$내경(內經)${\lrcorner}$에 대량(大量)의 편폭(篇福)으로 어떻게 양생하고 정기(正氣)를 보호해야 한다는 방법이 소개 되어 있다. 후세(後世) 역대의가(歷代醫家)는 그 내용을 더욱 충실(充實)케 하고 발전시켰다. 근대(近代)에 이르러서 중의학술(中醫學術)에 특유한 내용인 '미병학(未病學)'이 형성되었고, 그 이론체계 속에 아건강상태(亞健康狀態)의 예방과 치료에 관한 내용이 포함되어 있다.

We present here a new PCR-based cloning technique that allows the different PCR products during mouse embryogenesis. Recently, mRNA differential display described by Liang & Pardee (Science 257, 1992) and re-confirmed by Zimermann & Schultz (PNAS 91,1994). This method will detect the appropriate changes in the temporal patterns of expression or in the transition from maternal control to zygotic control as well as the functional difference of embryo with polyspermy or monospermy, the difference of expression between successfully hatched blastocyst and blastocyst failed to hatching, response to agents, and cell cycle regulation. By this methods, we have cloned an eDNA, which showed mouse 2 cell specific expression. Genomic DNA digested with EcoRI showed approximately 15 kb and then showed higher expression in fetal liver rather than adult liver. Furthermore, this gene is likely to have 2 mRNA by alternative splicing.

Unlike domestic railway transportation system in which majority of station are equipped with gate access controller and ticket office, it has been a very common practice in overseas railway transit or railway station that they use a pressure door mat, infrared-sensors or CCTV cameras so as to automatically determine the number of passenger onboard and alight and to reflect the information to their business (i.e., deployment of vehicles and human resources). The data collected by the automatic passenger counting (APC) system provides methods how to obtain the information about the number of passenger using the vehicles on the basis of date, time and stop(station) which enables large-scaled transit company to create profits through effective vehicle deployment and management of their employees. This paper addresses the basic features of the automatic passenger counting system using infrared sensor and describes those of the extended APC system in conjunction with wireless technologies such as GPS, WLAN or Cellular network.

Spline curve scheme is the most valuable tool for the CAD of industrial products. Hence, the development of a new, effective curve scheme can have immediate impact on the current design industries. This paper develops and implements a new methodology for the implementation of the visually continuous class of splines which can produce a more flexible and diverse curve shapes. This class of splines has advantaged over existing splines in that it can accommodate wider range of shapes while maintaining the interpolators property of the ordinary cardinal splines. Most importantly, we avoid using the previous method of implementing G$^1$ curves, where users must specify scalar values for the control of curve shapes. We derive and implement an easy-to -use transformation between the user-specified graphical tangent vectors and the actual parameters for the resulting curve. Since the resulting curve shape reflects original tangential direction faithfully, CAD users can simply represent approximate curve shapes with proper tangents. Consequently, a simple user interface device such as a mouse can effectively produce a various spline curves using the proposed spline tool.

It requires long time and high cost for an apprentice engineer to reach the level of getting various experiences of engine space machinery and preparing for emergency situations. Therefore reducing the time and cost, several types of simulator that give the very similar surroundings to the ship engine room, relevant to STCW-95 are used for systematic education and training to get many experiences and good judgement in emergency. Since most simulators that are operated in Korea were imported from foreign countries, it is difficult to directly implant the amendments of STCW Convention and reflect International Maritime Organization (IMO) model courses. This study describe a development of marine auxiliary boiler simulator that makes the apprentice engineer easier to understand the relationship between equipments in steam system such as auxiliary boiler, exhaust gas boiler, and steam turbine.

Max-plus algebra is a nonlinear system comprised of two operations, maximization (max) and addition (Plus), which are corresponding to the addition and the multiplication in conventional algebra, respectively. This methodology is applicable to many discrete event systems containing the state transition with the maximization and addition operation. Timetable with connection is one of such systems. We present the method based on max-plus algebra, which can make up timetable considering transfer and analyse its stability and robustness. In this study, it will be shown how to make up the timetable of the urban train and analyse its stability using Max-Plus algebra.

The purpose of this study is to understand the context of mental hospital admission and discharge related with the stakeholder and to find out issues about public management on mental health disabilities. To this process, the more effecive alternative policies for mental health will be offered. As a research tool, the qualitative study was used, and the 6 case were analyzed. Through this study, we find 5 theme such as admission type occurred outside public management, uneffective public management in mental hospital treatment, long-term treatment mechanism occured in mental hospital, helplessness and role distortion of public follow-up system. According to the mental health law, mental hospital admission and discharge on mental health disabilities is to managed public system. But public management with mental health disabilities did not work on. In this results, we are find infringement on mental health disabilities. According to these findings, several suggestions are offered for better policies about admission and discharge procedures managed by public system.
