대학교육력 강화와 질 제고에 대한 관심이 증대되면서 학습자의 학업성취와 학습과정, 다양한 학습활동이 대학교육의 주요한 성과변인으로 작용하고 있다. 이러한 맥락에서 공학교육의 질적 제고를 위해서 학습성과, 교육여건, 교육환경 뿐 아니라 공학교육에 참여하는 학습자 중심으로 그들이 어떠한 학습을 하고 있는지 관심을 기울일 필요가 있다. 본 논문에서는 공과대학 학생들의 전반적인 수업 내 활동은 어떠한지 살펴보고, 수업 내 학습활동 촉진을 위한 교수-학습지원 방안을 제안하고자 하였다. 연구결과 공과대학 학생들은 수업에서 교수들이 요구하는 활동에는 활발히 참여하나 그에 반해 자기주도적인 학습 참여는 덜한 편이었다. 과제수행에 관한 사고력 증진 활동은 자주 수행하였으나, 일상생활에 응용하거나 비판적 사고 활동은 많이 하지 않는 것으로 나타났다. 수업내 수강생들과 활발한 협력이 이루어졌고, 수업에 대한 태도가 성실한 편이었다. 이러한 결과를 바탕으로 공과대 수업내 학습활동을 촉진하기 위해서는 학습자의 자기주도적 학습 및 사고력 증진을 위한 교수-학습지원이 필요하다.

Since the release of safety standard IEC 61508 which defines functional safety of electronic safety-related systems, SIL(Safety Integrity Level) certification for railway systems has gained lots of attention lately. In this paper, we propose a new design technique of the computer board for train control systems with high reliability and safety. The board is designed with TMR(Triple Modular Redundancy) using a certified SIL3 Texas Instrument(TI)'s TMS570 MCU(Micro-Controller Unit) to guarantee safety and reliability. TMR for the control device is implemented on FPGA(Field Programmable Gate Array) which integrates a comparator, a CAN(Controller Area Network) communication module, built-in self-error checking, error discriminant function to improve the reliability of the board. Even if a malfunction of a processing module occurs, the safety control function based on the proposed technique lets the system operate properly by detecting and masking the malfunction. An RTOS (Real Time Operation System) called FreeRTOS is ported on the board so that reliable and stable operation and convenient software development can be provided.

The Profile of Mood States (POMS) is the most widely used self-report instrument for the measurement of affect or mood in clinical and nonclinical populations. This paper reports on the translation and testing of a Korean version of the POMS. The translation involved three steps: translation, checking agreement, and panel discussions to arrive at consensus. Then, the Korean version of the POMS was tested with a sample of 47 healthy Koreans who lived in the U.S.; they completed the instrument in the morning, at the beginning of work and in the evening, at the end of work. Internal consistencies for the total scale and subscales were high (alphas ＝ .93 and .94). Face and content validity and the cultural relevance of the Korean version of the POMS were tested through review by five bilingual Korean nursing scholars who were familiar with Korean culture and with the current literature on affect, feeling or mood in both English and Korean. The Korean version of the POMS was then compared with the Haeok Fatigue Behavior Check-list and demonstrated with concurrent validity (r ＝ .87, p ＜ .001). Construct validity was established by demonstrating significant differences between the scores on the Fatigue and Vigor subscales (p ＜ .001) at the beginning work and at the end of work.

Purpose: This study was done to investigate the relationship of knowledge related to disease, awareness and practice of inhaler use in asthmatic patients. Method: The participants in this research were 124 patients with asthma who used inhalers, and were admitted to hospital or attended outpatient asthmatic clinics. Data were collected using a self-administered questionnaire which consisted of demographic characteristics, illness-related characteristics, and tools to measure knowledge of disease, awareness and practice related to inhaler use. Results: Knowledge related to disease was statistically significantly different for age (p<.001) and marital status (p=.017). The mean score for awareness of inhaler use was significantly higher than the mean score for practice in inhaler use (p<.001). There were significant correlations between awareness and practice of inhaler use (p<.001), knowledge related to disease and awareness of inhaler use (p<.001), and knowledge related to disease and practice of inhaler use (p<.001). Conclusion: Results indicate that due to the variation in degree of illness in patients with asthma, there is a need to develop appropriate education programs for people of different ages and also precise ${\alpha}$ II content for use of inhalers method of checking capacity washing and storing as well as directions about different kinds of the inhalers.

In order to investigate psychological and behavioral characteristics of homosexuals and to present evidence that homosexuals are in danger of HIV infection in Korea, this study was done by self-administered questionnaire and then direct interview with the 28 (35%) HIV infected homosexual/bisexuals of 79 HIV infected persons reported in 1992. Homosexuals without heterosexual activity were 9 and the others were bisexuals. Sixty-five percent of respondents had a guilty conscience for their homosexual activty. Twenty (71%) were in twenties and 5 (18%) in thirties. Twelve(43%) were detected via health card checking by health office, 21% by blood donation, 18% by hospital visit, and 7% by partner notification. Motivations for homosexual activity were curiosity (36%), temptation or recommendation (14%) and compulsion (11%). Eighteen (72%) never used condom on anal sex. Nine of 26 respondents had experience for anal sex with foreigners. Fourteen (54%) of 26 respondents had history for sexually transmitted diseases. Fighty percent did not have sexual contact after HIV infection and the others usually used condom. It was confirmed that over 57% of the respondents were infected within 1 year before HIV diagnosis and over 82% within 2 years. These data suggest that HTV infection among homosexual group is rapidly spreading.

Purpose: Military maintenance involves corrective and preventive actions carried out to keep a system in or restore it to a predetermined condition. This research develops an optimal maintenance cycle for aviation oil testing equipment with acceptable reliability level and minimum maintenance cost. Methods: The optimal maintenance policy in this research aims to satisfy the desired reliability level at the lowest cost. We assume that the failure process of equipment follows the power law non-homogeneous Poisson process model and the maintenance system is a minimal repair policy. Estimation and other statistical procedures (trend test and goodness of fit test) are given for this model. Results: With time varying failure rate, we developed reliability-based maintenance cost optimization model. This model will reduce the ownership cost through adopting a proactive reliability focused maintenance system. Conclusion: Based on the analysis, it is recommended to increase the current maintenance cycle by three times which is 0.5 year to 1.5 years. Because of the system's built-in self-checking features, it is not expected to have any problems of preventative maintenance cycle.
