This study is on the early historical background and the process of development of modern architecture in Thai, during the period from 1782(King Rama 1) to 1934(King Rama 7). Thai started tn form a connection with western nations from the late 18C, founded the Bangkok Dynasty. Since then, Thai was increasingly influenced by western civilization and this trend included an increasing influence of western architecture. In this paper, the centeral objective is to observe the architectural change during the period from King Rama 1(1782-1809) to King Rama 7(1925-1934). This can be divided into three period. During the first period, from King Rama 1 to King Rama 3(1824-1851), Thai architecture showed a tendency to follow the preceding traditional example and to imitate Chinese architecture. The second period is from King Rama 4(1851-1868) to King Rama 5(1868-1910). During this period, Thai architectural design was increasingly influenced by western concepts, specially European Neo-classicism Style. During the third period, from King Rama 6(1910-1925) to King Rama 7(1925-1934), Thu had been enjoying extensive commerce with western nations. The great developments in the field of architecture during this reign were apparent in the construction of public utilities and facilities. These buildings were designed by western architects. At this time, modern architectural concept of western was introduced.

The purpose of this study were to evaluate and compare the balance ability at different conditions in normal 20 to 29 years old on unstable platform, KAT 2000(Breg, Inc., Vista, CA. 1994). Static and dynamic BI(balance index) were measured 3psi and 5psi surface conditions. Static tests were done on right and left leg separately, then both legs together with the feet apart 20cm with the eyes opened and closed. Dynamic tests were done on both legs together with apart 20cm with the eyes opened. A dynamic test was performed in which the subject moved platform in a circular manner to chase a moving object on a computer screen. Seventy healthy students(average 21.6 years, male, female) were tested. In this study applied the paired t-test and correlation to determine the statistical significance of result. The results were as follow: 1) The mean static balance index of the Rt leg was on 3psi surface condition with the eyes opened, and that of the Lt leg was . 2) The mean static balance index of the Rt leg was on 5psi surface condition with the eyes opened, and that of the Lt leg was . 3) The mean static and dynamic balance index of both legs were , on 3psi with the eyes opened, and , on 5psi respectively. 4) The mean static balance index of the Rt leg was on 3psi surface condition with the eyes closed, and that of the Lt leg was . 5) The mean static balance index of the Rt leg was on 5psi surface condition with the eyes closed, and that of the Lt leg was . 6) The mean static balance index of both legs was on 3psi surface condition with the eyes closed, and that of the 5psi was . 7) The balance index on 3psi surface condition was significantly higher than that of 5psi (p<0.05, p<0.01). 8) The balance index with the eyes closed was significantly higher than that of the eyes opened (p<0.05). 9) The balance index on the left leg was significantly higher than that of the right leg (p<0.05, p<0.01). 10) There was no correlation between static balance index and dynamic balance index. 11) Therewas no correlation between weight or height and balance index.

조성 변조된 비정질 Fe80Zr20박막의 자기적 성질과 기계적 성질 변화를 전해적 방법에 의한 수소 취입 시간의 함수로 측정하여, 그 상관 관계를 연구하였다. 박막의 Young's modulus는 진동 cantilever 시료의 공명 주파수를 , 10-4nm의 측정 감도를 지닌 laser heterodyne interferometer를 써서 측정하였다. 농도 2N의 인산 전해액에 침적된 시료에 26.3mA/cm2의 전류를 흘려 이루어진 수소취입에 의해, Fe80Zr20 박막의 포화자화 정도는 8배, Young's modulus는 18배 가량 증가하였다. Fe80Zr20박막의 자기적 성질의 변화가 원자적 scale의 미세 구조 변화에 의한 것이라는 간접적인 증거를 제공하였으며, cantilever 시료의 공명주파수 측정을 통하여 박막재료의 기계적 성질을 연구할 수 있는 새로운 가능성을 제시하였다.

미국흰불나방(Hyphantria cunea Drury) 번데기의 휴면 종료에 미치는 탈피호르몬 20-hydroxyecdysone (20-HE)의 처리효과와 또한 호르몬처리로 유기된 휴면 후 성충발육 모습을 정상적인 성충발육과 비교하기 위하여 본실험을 수행하였으며, 그 결과 다음고 같다. 광주기 16L.8D와 에서 여러가지 다른 기간동안 저장했던 휴면번데기에 20-HE를 처리했을 때 가장 높은 휴면 종료율은 가장 오랫동안 처리된 군에서 나타났고 45일 동안 저장했던 휴면번데기에서 가장 낮은 종료율을 보였다. 우화에 필요한 기간은 저온()처리가간에 반비례하였고, 또한 저온처리기간이 길어질 수록 20-HE에 대한 민감도는 높아졌다. 번데기 휴면기간은 그들이 16L.8D 광조건에 처리되었건 혹은 지속적이 암조건에 저장되었건 간에 거의 같았고, 또한 저온처리없이도 성공적으로 성충이 출현하였다. 정상적으로 무화(휴면없이)하는 번데기의 산소소모율은 전형적인 U자 모양을 보였지만 20-HE에 처리된 휴면 번데기의 산소흡수량은 천천히 증가하다가 처리 후 14일에 급격히 증가하였다. 번데기 휴면은 성충조직을 형성하기 이전에 들어갔으며, 정상적으로 발육하는 번데기나 또는 20-HE에 처리되어 발육하기 시작하는 휴면 번데기 모두에서 성충조직 형성시기와 대사율이 증가하기 시작하는 시기는 일치하였다. 탈피호르몬처리로 발육을 시작한 휴면 번데기의 혈림프와 지방체에서 분리된 단백질종류는 모두 정상적으로 발육하는 번데기의 조직에서와 같았다.

고출력 IC회로의 방열재료 및 전기접점재료로 이용되고 있는 W-Cu복합재료를 기계적합금화법으로 제조하였다. 기계적합금화한 분말을 300MPa로 폭 16mm, 높이 4mm의 원반형으로 제조하였다. 소결은 1200˚C에서 1400˚C까지 수소분위기에서 행하였다. 이렇게 제조된 시편의 절단된 면을 연마하여 SEM으로 관찰하였다. 균질한 W-Cu복합재료를 10시간 기계적합금화를 행한 후에 얻을 수 있었고, 1330˚C에서 1시간 소결한 시편의 경우 거의 99%에 가까운 치밀한 조직을 얻을 수 있었다. 또한 기계적합금화시간이 증가함에 따라서 Fe의 혼입은 직선적으로 증가하였으며, 이로 인한 금속간화합물상의 형성은 W입자 성장을 방해하고 경도를 증가시켰다.

This study was done to determine a new qualitative base for educating and evaluating patients by comparing a 60 or over age group with a 20-30 age group when rising from supine to erect stance. Sixty normal adults were devided into 60 or over and 20-30 aged groups. Each persons was asked to standing from the supine position. This process was recorded by two video cameras. The results was classified into the three existing movement categories. And then they were analyzed by percent rate. The results showed that each group had its own different and special characteristics. This means that physical therapists need to select the best motor patterns according to age in teaching functional tasks such as rising from supine to erect stance.

This study was designed to develop an objective method of strength measurement of muscles controlling the wrist joint in normal subjects. Forty subjects (20 male, 20 female) with a mean age of 22 years, were tested isokinetically at and . Results were as follows, 1) Peak torque for wrist flexors, extensors were significantly different for both speeds, but wrist ulnar deviator, radial deviator peak torques were not, 2) Mean values for all muscle groups controlling the wrist were not significantly different for both speeds in the female group, 3) All mean values at both and were significantly different between males and females, 4) Means and standard deviations of wrist joint angle of movement at peak torque were determined.
