  • This study is a descriptive research to identify lifestyle for health promotion, health condition, and degree of life satisfaction based on Korean elderly's physical constitution. The interviewee of this research was 53 outpatients of Oriental herbal medicine hospitals who are the residents either in Seoul or Taegu city. The data collection was performed during the March to the November of 1999. The research tools used for the measurement of the lifestyle for health promotion was "The Health Promoting Lifestyle Profile" developed by Walker, Sechrist and Pender. Measurement of the health condition was carried out using CMI(Cornell Medical Index) developed by Brodman, Erdmann, Lorge and Wolff. The Index for degree of the life satisfaction of elderly developed by Yun Jin was utilized to measure the degree of life satisfaction. Data analysis was performed using SPSSWin 9.0 software. In some cases, frequency, percentile, t-test, ANOVA or Pearson Correlation was also used to meet the specific research purposes when necessary. Tukey test was done for the post test. The conclusions are as follows. 1) The ANOVA test showed a significant difference in the lifestyle for the health promotion depending on physical constitutions of the interviewee. According to the Tukey test, 태음인 ($103.67{\pm}16.81$) performed better lifestyle for the health promotion than SOEMIN(少陰人, $85.34{\pm}12.69$) and 소양인($88.47{\pm}16.81$) (F=6.72, p=.003). 2) The result of the Pearson Correlation showed a positive correlation between the lifestyle for health promotion and health condition. As a result, the group practicing lifestyle for health promotion maintained a good health condition. Result of the Pearson Correlation also showed a proportional correlation between the lifestyle for health promotion and life satisfaction. Accordingly, the group practicing lifestyle for health promotion maintained a high degree of life satisfaction. Finally, the result of the Pearson Correlation showed a proportional correlation between the health condition and the degree of life satisfaction. Consequently, the group in a good health condition showed the high degree of life satisfaction.

  • To develop a scouring method for the high-grade quality and the high value added of flax for spinning, it was measured and analyzed weight loss and degree of injury with change of scouring concentration, time, temperature and pH. We got the f ollowing results; Firstly, in case that flax was scoured at a fixed condition, the weight loss and degree of injury of scoured flax under the no-cutting condition were lower than that of scoured flax under the cutting condition. Secondly, when flax was scoured with $Na_{2}CO_{3}$, it was obtained that the higher weight loss and degree of injury and weight loss with the increase of scouring time and condition. The degree of injury was lower than any other under the treatment condition of 4% $Na_{2}CO_{3}$concentraion for 2 hours. Finally, when alkaline scoured flax was rescoured by pectinase, enzyme activation effect was the most active under the treatment condition of pH 4 for 2 hours. The scouring effect was better than that of alkaline scouring only.

  • In order to reject the steady-state tracking error, it is common to introduce integral compensators in servosystems for constant reference signals. However, if the mathematical model of the plant is exact and no disturbance input exists, the integral compensation is not necessary. From this point of view, a two-degree-of-freedom(2DOF) servosystem has been proposed, in which the integral compensation is effective only when there is a modeling error or a disturbance input. The present paper considers a robust stability of this 2DOF servosystem with nonlinear type uncertainty in the system, and a robust stability condition for the servosystem is introduced. This result guarantees that if the plant uncertainty is in the permissible set defined by the condition, gain tuning can be carried out to suppress the influence of the plant uncertainties and disturbance inputs.

  • 본 연구에서는 한강유역에 위치한 축분퇴비공장의 작업환경 조사를 위한 현장 평가로서, 설문조사 및 악취물질 측정을 통해 근로자들의 작업환경 만족 수준과 이에 영향을 주는 요인들을 규명하였다. 연구결과, 축분퇴비공장 근로자들의 작업환경 만족도에 영향을 주는 요인들로 일반 건강수준, 악취, 작업량, 분진, 흡연으로 조사되었으며, 이 중 일반 건강수준, 악취, 작업량이 전체 작업환경 만족도의 61.3%를 대변하는 것으로 나타났다. 통계적 유의성을 나타낸 작업환경변수로는 일반 건강수준(p$<$0.01), 악취 작업량 분진(p$<$0.05) 등 이었다. 결론적으로 일반 건강수준이 높은 근로자일수록 작업환경 만족도가 높았으며, 작업량이 상대적으로 많고 악취와 분진에 쉽게 노출된 공장의 근로자일수록 작업환경 만족도가 낮은 것으로 분석되었다. 흡연을 하는 근로자는 작업환경 만족도가 낮게 나타냈으나, 통계적 유의성은 없는 것으로 분석되었다. 따라서 한강유역 축분퇴비공장 근로자들의 작업환경 만족도를 제고시키기 위해서는 공정 중 악취와 분진농도의 발생을 저감시켜야 할 것으로 판단된다. 그러므로 축분퇴비공장의 악취 및 분진농도의 발생을 최소화할 수 있는 처리공정 및 관리체계 정립이 시급하며, 이는 궁극적으로 축분퇴비공장 작업자의 건강 뿐만 아니라 주변 마을 정주민의 생활환경개선효과를 유발할 수 있다.

  • The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

  • A theoretical equation was proposed to consider the effect of ponding for the excess pore water pressure in agricultural reservoir on soft clay ground. The value of excess pore water pressure predicted using the proposed equation was compared to those predicted with the Terzaghi's method and the finite difference method(FDM), respectively, for the purpose of verification. The degree of consolidation according to ponding predicted by applying the proposed equation was close to the observed degree of consolidation on the double drainage condition(at DP-3) but it was less than the observed degree of consolidation on the single drainage condition(at DP-5). The equation was very applicable to practice because the analysis result by the equation was close to the observed data.
