In order to investigate the generation of carbon monoxide and heat loss of incomplete combustion in compartment fires, an experiment was conducted in a small scale compartment by using methanol as a fuel. The concentration of carbon monoxide and the toxicity parameter showed high values when the mass air - to - fuel stoichiometric ratio is under 1.0. The constitution of the combustion gas was showed to estimate it from the . The heat loss due to incompleteness of combustion is about one third of heat of combustion in case of under 1.0.

현대인들의 불규칙한 생활과 서구화된 식습관에 의해 대장 및 직장 질환이 증가하고 있는 추세로, 특히 직장암은 전체 대장암의 50%를 차지하고 있다. 초기 직장암의 경우 표면으로 돌출되는 부분이 없으므로 초음파로 조직 내부를 보지 않으면 직장 농양으로 오진하는 오류를 범하기도 한다. 그러나 초음파 진단을 하더라도 직장암의 병기에 따라 농양과 육안으로 구별이 어려운 경우가 있기 때문에 보다 정확한 진단이 필요하다. 그러므로 본 연구에서는 직장암과 농양 영상에 대한 컴퓨터 알고리즘을 이용하여 정량적인 분석을 하였다. GLCM을 적용하여 정상 20증례와 농양, 직장암 각 20증례를 분석영역($50{\times}50$ 픽셀)으로 설정하고, 각 영상에서 Autocorrelation, Max probability, Sum average, Sum variance 4가지 파라미터를 비교하여 분석하였다. 결과적으로 Autocorrelation, Max probability, Sum variance 3개의 파라미터에서는 100%, Sum average 파라미터에서는 암 95%, 농양에서 90% 이상의 높은 병변 질감 검출 효율이 나타났다. 이러한 파라미터들이 직장에서의 정상조직, 농양조직, 암조직 간의 판별의 기준으로 가치가 있다고 사료된다. 임상에서의 활용정도에 따라 컴퓨터 보조진단으로서의 충분한 유용성을 볼 수 있을 것이다.

This study examined those problems noticed under the Asymptotically Generalized Least Squares estimator in evaluating a structural model of physical health. The problems were highly correlated parameter estimates and high standard errors of some parameter estimates. Separate analyses of the endogenous part of the model and of the metric of a latent factor revealed a highly skewed and kurtotic measurement indicator as the focal point of the manifested problems. Since the sample sizes are far below that needed to produce adequate AGLS estimates in the given modeling conditions, the adequacy of the Maximum Likelihood estimator is further examined with the robust statistics and the bootstrap method. These methods demonstrated that the ML methods were unbiased and statistical decisions based upon the ML standard errors remained almost the same. Suggestions are made for future studies adopting structural equation modeling technique in terms of selecting of a reference indicator and adopting those statistics corrected for nonormality.

In this paper, we derive the approximate maximum likelihood estimators of the scale parameter and location parameter in an exponentiated logistic distribution based on multiply Type-II censored samples. We compare the proposed estimators in the sense of the mean squared error for various censored samples. We also propose and compare the estimators of the reliability function by using the proposed estimators of the parameters.

These were two main purposes of this study. The first was to research the relevance between gross motor function measurement (GMFM) and the spatiotemporal parameters of gait in children with cerebral palsy. The second was to research the relevance between gross motor performance measure (GMPM) and the spatiotemporal gait parameters. Twelve children ($6.0{\pm}1.8$ years) with cerebral palsy participated in this study. GMFM and GMPM were performed and the spatiotemporal parameters of gait were measured by using WalkWay MG-1000. There were no significant correlations between the GMFM score and the stride length, step length, step width, cadence, and velocity (p>.05). The GMPM score also had no significant correlation with the spatiotemporal gait parameter (p>.05).

본 논문은 신체의 운동 이후에 자세의 움직임 변화를 주고, 다중파라미터를 이용하여 자세균형의 변화를 나타내는 시스템이다. 신체에 동작을 주어 자세 균형의 변화된 신호를 시스템에서 측정하고, 이를 분석하여 자세균형의 변화상태를 나타냈다. 신체의 자세변화는 머리와 상체를 움직여서 변화를 주었고, 자세 변화로 발생된 신호는 파라미터의 형태로 구성하여 측정할 수 있도록 하는 시스템으로 구성하였다. 데이터 신호는 데이터 획득 장치를 통하여 얻고, 신호 전달 과정에서 신호를 분석하여 논리적으로 분석하여 자세에 대한 평가를 할 수 있도록 조정하였다. 측정파라미터의 항목은 시각(Vision), 전정기관(Vestibular), 체성감각(Somatosensory), 중추신경계(CNS)이고, 측정파라미터의 평가는 안정성(Stability)으로 확인하였다. 본연구의 결과로 운동부하에 따른 인체의 자세변화에 따른 신체의 변화 상태를 분석할 수 있는 시스템을 구성 할 수 있음을 확인하고, 다양한 신체적 파라미터를 통한 모니터링 기능을 갖춘 시스템관리가 형성 될 것으로 예상한다.

Objectives : Cancer is the leading cause of death in Korea. Therefore, a National Cancer Screening Program (NCSP) was launched in 1999. This study planned to evaluate the performance of the NCSP to identifying the influencing factors in relation to characteristic public health centers. Methods : To analyze the performance, the database of the NCSP records for 2002 was used. The performance index was measured by the goal achievement rate, which was defined by the real number of screenees against the expected number of screenees. Also, a survey was conducted by a self-administered questionnaire to identify the factors associated with the goal achievement rate. The questionnaire was divided into two sections. In the first section, the individual characteristics of the program coordinator in each public health center were measured, and second section was comprised of questions about the organizational characteristics associated with the NCSP. A total of 121 subjects from 241 public health centers completed the questionnaire. Results : Of the 121 public health centers (50.2% response rate), the average goal achievement rate was 72.8%. The results of the regression model showed that public health centers located in rural area (parameter estimates=38.2) and had great support from a head of center or province (parameter estimates=0.20) and tended to have higher goal achievement rates. However, the characteristics of the program coordinator, especially their knowledge of and attitude toward cancer screening, were not significantly related to the goal achievement rates. Conclusions : It appears that the most important associated factors to the goal achievement rate in the NSCP were the location of the public health center and the support for the NCSP from the head of the center or province.

The present study was performed in order to clarify the significance of serum amyloid A(SAA) estimation for the diagnosis of bovine amyloidosis and SAA as a useful parameter for the health status in herds. Twelve dutch dairy cows with final diagnosis(2 with amyloidosis, 3 with acute inflammatory disease and 7 with chronic inflammatory disease) were used to charify the significance of SAA determination for the diagnosis of bovine amyloidosis. The SAA concentration in the group of inflammatory disease was higher than that of amyloldotic group. Further the SAA value in the group of acute inflammatory disease was higher than that of chronic ones. To clarify the significance of SAA estimation as a useful parameter for the health status in herds, two Korean dairy farms(A and B) were selected and the SAA concentration was determined in total 76 cows(49 from A farm and 27 from B farm). The SAA concentration in cows from A farm was ranged with 0～169%. The cows with high level of SAA(31～169%) had the disease histories(1 with retained placenta, 3 with chronic mastitis, 2 with acute mastitis, 1 with abortion and acute mastitis, 1 with ovarian dysfunction, 1 with downer cow syndrome and 1 with laceration of the teat). The SAA value in the cows from B farm was ranged with 0～29% and disease history was not detected. In conclusion the SAA determination only is thought to be difficult for the diagnosis of bovine amyloidosis. Furthermore SAA estimation is thought to be a useful parameter for the health status in herds.

The purpose of this study is to find out the effects of taping therapy on muscle activities between the group of taping therapy treatment and control group before or after exercises. The subjects are 18 S college's healthy male students who do not have any problems in the legs and could bend the knee joint normally. Considering physique, condition of health and capacity for locomotion, 3 groups of each 6 persons for the experimentation were classified. Three groups composed of control group without taping therapy treatment for control group, group I with taping therapy treatment only before the experimentation and group II with taping therapy treatment during 24 hour. before and after the experimentation. EMG MP150 was used to evaluate the parameter of the lower leg's muscle activities the exercise before 5 min. after 10 min. and after 24 hour. for the experimentation. Compared with control group, group I and group II had more increased muscle activities in vastus lateralis and rectus femoris and was statistically significant. And group I and group II also had more increase in muscle activities than control group in vastus medialis, although there was no statistically significant. We found that taping therapy increased muscle activity positively. The application of taping therapy could be used not only for preventive effects for sports man but also therapeutic effects for general people.
