As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

The measuring system controlled by microcomputer was constructed in order to measure the three dimensional flow field behind an axial flow compressor rotor. Detailed measurements were made of the flow field behind an axial flow rotating blade row using this system and a 45°single slanted hot wire. The interaction of the wake with the annulus wall boundary layer, the secondary flow and the tip leakage flow results in slower decay and larger width of the wake. By the mixing of the wake with the strong secondary flow at the corner between the hub wall and the suction side, the wake near the hub wall has the largest width and the largest axial velocity defect. The reduction of the mass flow rate entails separation, stall and larger tangential velocity. In particular, as leakage flow become strong, it absorbs the wake and affects the flow at the full passage near the casing wall.

Blends of new thermotropic liquid crystalline polymer(TLCP) with poly(ethylene terephthalate)(PET) were prepared by the coprecipitation from a common solvent. The thermal, mechanical properties and morphology of the blends(2wt%, 5wt%, lOwt% and 20wt% TLCP/PET) were examined. In the blends, liquid crystalline phase did not reveal any significant macrophase separation and thermal degradation at the processing temperature. According to the scanning electron micrograps, the TLCP domains in matrix were found to be more or less finely dispersed with 0.2㎛ to 0.4㎛ in size and interfacial adhesion between the TLCP and matrix polymer was excellent. Results of mechanical property measurement show that modulus of TLCP/PET blend was enhanced with increasing TLCP content.

This study investigated that the effect of rewetting agent on dentinal microtensile bond strength (μTBS). Human molars were sectioned to expose the superficial dentin surfaces. Samples were divided into two groups according to type of adhesives-Single Bond (S) and One-Step (0)], and again subdivided into five groups by different dentin surface treatment-dry for 15s (D) , blot dry (BD) or dry for 15s, and rewet with different rewetting agents[distil1ed water (DW), Gluma Desensitizer (GD) and Aqua-Prep (AP)]for 30s. After application of adhesive, composite resin was built up on the bonding surface. Each tooth was sectioned to obtain stick with 1mm^(2) cross sectional area and the μTBS was determined by EZ test. In the S group, the mean μTBS of GD, AP and BD group was significantly higher than that of DW and D group (p < 0.05). In the 0 group, the mean μTBS of AP, GD, BD and DW group was significantly higher than that of D group (p < 0.05). The data suggested that Gluma Desensitizer and Aqua-Prep could be successfully used as rewetting agents, and Distilled water could be acceptable in aceton based adhesive system only.

조진호,강희동 경북대학교 센서기술연구소 1997 연차보고서 Vol.1997 No.-

본 연구에서는 향후 중요한 의료 복지시스템으로 국내외에서 널리 쓰이게 될 MSGC형 온라인 X선 촬영 사진 촬영 장치를 개발하고자 하였다. MSGC형 은라인 X선 촬영장치는 기존의 X선 필름에 비해 조사선량을 크게 낮출 수 있으며 계조도(gray level)및 범위가 디지털 x-ray 시스템에 비해 훨씬 넓다. 그리고 MSGC형 센서는 비슷한 메카니즘으로 작동되는 MWPC형 위치검출센서 보다 높은 해상도를 얻을 수 있으며 센서제작에 대량화와 간편성을 동시에 제공할 수 있는 잇점이 있다. 본 연구는 MSGC센서를 제작하여 이로부터 X선 조사선량에 관계되는 기체 증폭펄스를 얻기 위한 연구 분야와, 이 센서를 이용하여 영상이 얻어질 수 있도록 시스템을 제어하고 영상을 재구성 및 처리하는 두 가지 연구 분야로 나누어 진행된다. MSGC형 센서개발에서는 해상도가 높고 기체증폭이 안정적으로 일어날수 있는 센서를 설계 제작하였고 다양한 실험자료를 수집하였다. MSGC형 센서 개발에서 핵심부분은 기판의 재질과 마이크로스트립형 전극 그리고 챔버 및 기체 증폭이 일어났을 때의 펄스를 샤프하게 분리시켜 계수할 수 있는 기술이다. 디지털 X선 장치 제어 및 영상처리 연구에서는 1차 년도에 제작된 제어 컴퓨터와 X-ray 인터페이스 회로가 가진 수동 조작의 불편함, 타이밍 제어시 오차 발생 및 X-선 Expose속도의 한계 등의 문제점을 개선시킨 인터페이스 보드를 개발하였다. We have developed the MSGC type on-line digital radiography system that will used widely in medical welfare system in future. The MSGC type can reduce the X-ray exposure to the object significantly as compared with X-ray film and its the dynamic range of gray level is more wide than the conventional digital X-ray system. And the MSGC type sensor can obtain much higher resolution than the position detecting sensor of MWPC type which has a similar mechanism to MSGC type and also it can provide an advantage of mass-production and a simplicity to produce the sensors. We divided into two research fields. One is the field of implementing the MSGC sensor and measuring pulses produced by gas multiplication related with the X-ray. The other field is developing the method of controlling digital image acquisition part, image reconstructing, and processing. In the development of MSGC type sensor, we designed and implemented the sensor with a high resolution and a stable gas multiplication. And we collected various experimental data. In the development of MSGC type sensor, the core parts are the materials of substrate, microstrip type electrode and chamber, and technique to split the pulses of gas multiplication sharply and count them. In the field of system controlling and image processing, we developed the new-interface board which has been improved some problems in the first research step, i.e. inconvenient operations of control computer and X-ray interface circuit, error occurrence in timing control, and the limitation of X-ray expose velocity.

강남미,유경희,김성재,조남옥,최희정 서울대학교 간호대학 간호과학연구소 1996 간호학 논문집 Vol.10 No.1

This study was conducted by critical review analyzing literatures of theories focused on changes of health behaviors. 5 theories-TRA, HBM, Self-Efficacy, Social Support, and Locus of Control-were selected among many theories of health behaviors. Theories were summarized, and models and concepts of theories were described. The results of this study were follows : 1. health behaviors could be classified into preventive behaviors and curative behaviors. 2. Most conceran of previous studies in this field was on health behavior execution itself or on its outcome. 3. the focus of previous studies was on initiation, maintenance, facilitation, and change of preventive and curative behaviors. 4. Factors affecting on health behaviors were demographic factors as exogenous variables and intrapsychic and extrapsychic factors as endogenous variables. 5. Previous studies tested predictability and explicability of these theories onhealth behaviors and identified factors affecting health behaviors most. 6. concepts of TRA, SELF-Efficacy, and Social support had higher explicability on health behaviors than concepts of HBM and Locus of control. From results of this study, we suggested the direction and considerations for futher nursing studies related with these theories. And we derived testable propositions from relationship between concepts and each others.

강희동,조진호,박정병 경북대학교 센서기술연구소 1995 연차보고서 Vol.1995 No.-

Digital Radiography 장치로 응용하기 위한 1차원 MWPC를 이용하여 X-선 위치검출기를 설계 및 제작하였다. 위치검출 방법은 병렬판독법으로 얻으며 스캐닝장치를 이용해 X-선 영상을 얻는다. 제작한 검출기의 위치분해능은 0.8㎜이고, 동시성 선택회로를 고안하여 위치분해능을 0.4㎜로 향상시켰다. 실제 얻은 디지탈 값에서 각 채널에 대한 보정인자를 곱함으로써 영상의 균일성을 증가시켰다. 디지탈 X-선 영상은 0.4㎜의 scanning 간격으로 각종 피사체에 대하여 320×320 화소의 영상을 얻었다. X-ray position detector was designed and fabricated. The detector was applied to digital radiography system. One-dimensional MWPC(Multiwire Propotional Chamber) is the main component of this system. The way of detecting the position of incident x-ray is the parallel readout method. Digital image data are acquired by using fan beam x-ray and a scanning system. The spatial resolution of the detector is 0.8㎜. Spatial resolution was improved by a factor of two(0.4㎜) with help of the coincidence selection circuit. Uniformity was improved by converting data with calibration factor for each channel. With help of scanning system which has 0.4㎜ scanning pitch, x-ray digital images of 320×320 pixels were obtained for a fish and a chicken's foot. Bone image is appeared clearly in these images.
