한국산(韓國産) 벼 20품종(品種)(주(主)로 도입(導入) 품종(品種)) 즉 수륙도(水陸稻) 찹쌀 및 멥쌀 각(各) 5품종(品種)씩에 대하여 그 조단백질량(粗蛋白質量)과 각획분(各劃分) 단백질의 량(量)을 분석 검토하였다. 멥쌀보다 찹쌀 그리고 수도(水稻)보다 육도(陸稻)가 평균으로 단백질함량이 많았으며 oryzenin 과 albumin의 각(各) 함량비(含量比)도 같은 경향을 보였다.

In the present study, we employed the confocal laser scanning microscopy (CLSM) system to visualize the blood flow field with $1{\times}1{\mu}m^2$ spatial resolution. Based on the confocal microscopic image of red blood cells (RBCs), we performed the velocity vector field measurement and evaluated characteristics of cell migration from the cell depleted layer thickness calculation. The rat and mouse's blood were supplied into a micro glass tubes in vitro. The line scanning rate of confocal microscopy was 15 kHz for a $500{\times}500$ pixels image. As a result, the red blood cell itself can be used as a tracer directly without any kind of invasive tracer particle to get the velocity vector field of blood flow by performing particle image velocimetry (PIV) technique.

Agricultural departmental curricular of the universities have been compared and analyzed with an exception of that of Chung Nam National University where agricultural chemistry department was established in 1979. The analysis reveals that major subjects covered by the undergraduate curricula of all the universities in agricultural cheimstry departments are in the fields of soil science, plant nutrition, agricultural chemicals, biochemistry, and fermentation technology or applied microbiology, although there are minor differences in curricula among universities. Besides, it must be pointed out that the ratio of students to teaching staffs, a significant index of the educational quality, is shown to be somewhat lower than expected for an appropriate college education. According to the analysis, the curricula of universities located in various areas in Korea do not show substantial differences among them, indicating that there is no locality. Thus, it may be recommendable to set up a unified curriculum of agricultural chemistry departments in Korea so as to achieve a balanced educational improvemet.

Johnson등 (1971)이 발표한 뷰렛법을 다소 개변하여 현미 중의 질소 함량 측정에 적용하여 보았다. 또한 고단백 품종의 선발에 이용할 수 있는지의 여부를 알기 위하여 염색법과 비교 검토하였다. 본 실험에 사용한 시료의 질소 함량은 $1.20{\sim}2.0%$이었고 뷰렛 흡광도와 질소 함량과의 관계는 고도의 상관 관계를 보였으며 상관 계수는 $+0.841^{**}$이었다. 그러나 염색법과는 달리 질소 함량이 높아 갈수록 상관계수는 떨어지는 경향을 보였다. 그러나 뷰렛법은 질소 함량이 2.0% 이상인 경우에도 정상관을 보이므로 적당한 조건하에서는 염색법보다 더 좋은 결과가 기대된다. 염색법 사용시 여과액의 희석시 완충액 대신에 증류수 사용 가능성을 아울러 검토하였다.

In this paper, we proposed a technique to recognize three states in stance phase of gait cycle. Walking assistive devices are used to help the elderly people walk or to monitor walking behavior of the disabled persons. For the effective assistance, they adopt an intelligent sensor system to understand user's current state in walking. There are three states in stance phase; Loading Response, Midstance, and Terminal Stance. We developed a foot pressure sensor using 24 FSRs (Force Sensing/Sensitive Resistors). The foot pressure patterns were integrated through the interpolation of FSR cell array. The pressure patterns were processed to get the trajectories of COM (Center of Mass). Using the trajectories of COM of foot pressure, we can recognize the three states of stance phase. The experimental results show the effective recognition of stance phase and the possibility of usage on the walking assistive device for better control and/or foot pressure monitoring.

혈류 유동 연구를 위해서는 심장의 맥동 유동을 만들어 내는 것이 중요하다. 본 연구에서는 동맥혈류의 유동 해석을 위해 새롭게 설계된 심장 박동 모사 맥동펌프의 제작 및 그 성능에 관하여 시험을 수행하였다. 피스톤 펌프를 이용한 기본몸체 설계를 수행하였고 직류모터와 엔코더를 사용하여 회전수와 가속비를 설정할 수 있도록 하였으며, 시험결과는 전 영역에서 맥동 유동의 분포를 잘 따르고, 반복되는 맥동 주기의 편차도 작게 나타남을 확인하였다.

In this study, static and dynamic stability estimations on the diecutter with finite element modelling were carried out to be creased and cut away printed sheet exactly. To cut away the sheet exactly, the large force should be pressured on diecutter. And which affects not only the quality of produced sheets but also the stability of diecutter. The analyses with and without the tare of diecutter were carried out with NASTRAN software on applying 400 ton force to its top and moving table respectively. It was known that maximum von-Mises stress of 221 Mpa in diecutter was occurred at the toggle, and it was smaller than the yield stress of 280 Mpa. And maximum deformation of 0.75 mm was occurred at the top table. The natural frequencies of 41, 102, 108, 115, and 134 Hz for the 1st, 2nd, 3rd, 4th and 5th mode, which had been determined by numerical simulation, were not coincided with the max. speeds of motor and moving table of 29 and 2 Hz. And which was verified by vibration test. Therefore it may be estimated that the structure of the diecutter is statically and dynamically stable.

This study was carried out to investigate the content of sulfur dioxide residues in the medicine prepared from crue drugs. Total 29 pills that contains salvia miltiorrhiza root, anemarrhena rhizome, fritillaria bulb, glehnia root, asparagus tuber, lycium fruit, moutan root bark, cimicifuga rhizome, pinellia tuber, dipsaci radix, codonopsis pilosula root, liriope tuber, achyranthes root, prepared aconite, aurantii fructus immaturus, corydalis tuber, dioscorea rhizome were examined by the modified Monier_Willams method. Sulfur dioxide were detectd in all the tested samples, and were found over MRLs (30 mg/ kg to medicinal herbs) in 8 samples (27.6%). Especilly, "i2" pills contains 132.46 mg/kg sulfur dioxide that is 4 times over than MRLs.

밀가루에 멥쌀(밀양 23호) 또는 통일찹쌀 가루를 10, 20 및 30% 대체한 복합분의 물리적 성질 및 제빵 적성을 검토하였다. 밀-밀양 복합분은 밀-찹쌀 복합분 보다 높은 점도를 보였다. 복합분의 파리노그라프 안정성은 밀가루 보다 짧았으나 최적 반죽발전 시간은 비슷하였다. 제빵 적성은 밀-밀양 복합분이 다소 좋은 결과를 보였고 대체로 밀가루(멥쌀 또는 찹쌀)를 20%수준까지는 대체할 수 있을 것으로 보인다. 10%수준으로는 밀가루 빵에 크게 손색이 없는 제품이 가능하였다.
