The purpose of this study was to investigate the effect of nutritional education on the knowledge and the practice & Perception of diet therapy, and on the level of FBG and HBAlc. The subjects were selected among the patients treated in the Inha University Hospital from June of 1996 until April of 1998. Educated group consisted of 20 patients who visited the diet-counseling department as a part of diabetic treatment. Non-educated group consisted of 20 patients who visited the diet-counseling department ignoring doctors prescription purpose. The knowledge and the practice & perception of diet therapy drinking & smoking habits, regular exercise, and general characteristics including family history were analyzed by questionnaires. FBG and HbAlc were measured before and 4 months after the treatment. The results were as follows : Both groups were composed of 12(60%) male and 8(40%) female respectively. The mean age of subjects was 51.4 years in educated group and 51.9 tears in non-educated group. The duration and %IBW were 5.9 years and 109.8 % in educated group and 5.5 years and 111% non-educated group respectively. There were no significant differences in drinking & smoking habits and regular exercise between groups. The diet therapy knowledge score was significantly higher in educated group(p<0.001, 5.8$\pm$2.3/10.0 vs 3.4$\pm$2.0/10.0). The diet therapy practice & perception score was also significantly higher in educated group(p<0.001, 5.6$\pm$2.3/10.0 vs 2.8$\pm$2.2/10.0). Levels of FBG and HbAlc in both group were reduced at 4 month after the treatment(-74.2 mg/dl and -1.4% in educated group vs -58.7 mg/dl and -2.0% in non-educated group). However, the reduced amounts of them were not significantly different. Therefore, nutritional education seems to be very important in improving the knowledge and the practice & perception of the diet therapy. However, it appears no direct influence in reducing FBG and HbAlc levels. Further studies on diabetic management by using more efficient, consecutive and intensive nutritional education methods are needed. (Korean J Nutrition 34(1):69-78, 2001)

The purpose of this study are to evaluate the dwelling quality of rural houses constructed with industrialized wall structures(ALC; Autoclaved Light weight Concrete, SRC; Steel Fiber Reinforced Concrete, ST'L; Steel Framed Insulating Panel), and to establish a method of dwelling quality evaluation. The questionnaire survey by mail was done, for investigating the residents' responses to indoor environment, durability, and economic aspect. The respondents are 118 residents living in rural houses constructed with industrialized wall structures. Physical elements of indoor environment(temperature, humidity, air quality, and noise level) were measured in three sample houses, which were selected considering of architectural characteristics. The findings are as follows; 1) As a result of questionnaire survey, residents' responses to dwelling quality are generally positive. 2) As a result of measurement, indoor environments of sample houses are in relatively comfortable condition. 3) As a summary of research, ALC and ST'L are evaluated as recommendable structures for a rural house.

This study is investigated the strength properties of ALC(Autocalved Lightweight Concrete) using SPS(Stone Powder Sludge), to develop recycling technique of SPS. At a given replacement percent of SPS and addition percent of foam, the results show that its the strength properties are equal or higher than the quartz used in a raw material of ALC, and it is also found that the addition percent of the foam and the strength properties have a certain relation of linear.

Porous materials were manufactured by hydrothermal treatment of waste bottle glass without foam agent. Factorial design was applied to analyze data by statistical methods and deal with the important factors for a process. The largest effect for porosity was for temperature of hydrothermal treatment. Amount of water and temperature-water interaction appeared to have little effect. The particle size of raw material was also identified as a major factor by one-way ANOVA and the porosity decreased as the size increased. The sintering temperature was not statistically significant for the porosity but was significant for the pore size. The porous material had compressive strength and thermal conductivity comparing with those of ALC (autoclaved lightweight concrete), although it has higher porosity than for ALC.

본 논문에서는 개인용 컴퓨터와 CCD 카메라를 이용하여 실시간처리에 의해 생산 공정에서 자동으로 경량기포 콘크리트 블록의 각종 치수 측정을 할 수 있는 시스템 설계방법을 제안하였다. 또한 제안한 치수측정 자동화 알고리즘은 실제 작업환경을 고려하여 이중에지를 고려한 경계결정방법, 작업공정내의 피사체의 진동을 고려한 단위길이 결정방법, 카메라의 곡률보정에 의한 치수오차 보정 방법 등을 적용함으로써, 고성능의 하드웨어 장비를 이용하지 않고서도 실제공정에서의 실험결과를 통해 모든 경량기포 콘크리트 블록의 치수에 대해 1mm이내의 오차를 보장하므로, 설계한 시스템이 적합한 치수측정 시스템임을 확인할 수 있었다.

커튼월의 단열성이 가장 취약한 패스닝 유닛 부분의 단열성을 향상시키기 위한 연구이다. 멀리온과 연결부위가 최소화 되도록 고안하여 제작하였고, 중간에 방진고무 및 실리콘으로 단열층을 형성하여 그 성능을 평가하였다. 무단열에 비해 방진고무 단열은 2.6℃~4.0℃의 온도차를 보였으며, 실리콘 단열은 2.4℃의 온도차를 보였다. 따라서 패스닝 유닛에는 단열층이 필요하다고 판단된다.

PLL is a key item of power converter for power quality compensation and power flow control. This paper proposes a novel 3-phase PLL that is composed of ALC and PI controller. The operational principle was investigated through theoretical approach, and the performance was verified through computer simulations with MATLAB and experimental works with TMS320VC33 DSP board. The proposed 3-phase PLL shows accurate performance under the voltage disturbances such as sag, harmonics. phase-angle jump, and frequency change.

경량기포콘크리트(ALC : Autoclaved Lightweight Concrete)의 내구성을 개선하기 위하여 투숩 및 투수, 편면동결융해 특성과 탄산화 특성을 실험하였다. 국산 ALC전용마감재는 방수용 도장재에 가까운 투습 및 투수성질을 갖고 있어 특성의 개선이 요구된다. 편면동결융해시험에서 마감재의 투습도에 따른 열화위치는 투습도가 클수록 외측에서 발생하였으나 투수에 의한 외부의 박리열화는 관찰되자 않았다. 탄산화는 수분의 함량이 작을수록 빠르게 진행되었으며 탄산화가 진행됨에 따라 기공량은 감소하였다. 탄산화가 완전히 진행되면 부피의 팽창으로 균열이 발생하였다.
