광학활성 1-${\alpha}$-methylbenzylphenylurea 유도체의 bensulfuron-methyl, pyribenzoxim에 대한 약해경감효과를 조사하였다. 대부분의 유도체가 담수토양처리시험에서도 제초제 bensulfuron-methyl에 의한 벼의 근부신장 저해에 대하여 높은 약해경감효과를 나타내었다. 특히, S-이성체의 2,3-diCl 치환체와 2-F-4-Me 치환체는 dymuron 보다 4배 높은 약해경감효과를 나타내었으며 두 치환체들은 동시 혼합처리뿐만 아니라 4일 후의 지연처리에서도 bensulfuron-methyl의 약해를 효과적으로 경감하였다. S-이성체의 2-F-4-Me치환체는 벤조산계 제초제 pyribenzoxim에 대해서도 지상부, 근부 모두 95%의 높은 약해경감효과를 나타내었다.

The constant .DELTA.K fatigue tests are performed in SS41 and its weldments to investigate crack opening behavior and fatigue crack propagation behavior at each parts of weldment and its boundary layer. The weldments were annealed after welding for the purpose of relieving residual stress. Every weldments has notch at weld metal zone, and fatigue crack propagates from weld metal zone to vase metal zone perpendicular to weld line. The Laser ISDG method is used in order to determine the crack opening ratio, this method is more precise than indirect measurement method, and faster and easier than other direct measurement method.

Tic disorder which is purposeless, repeated, unexpected, involuntary behavior and voice can be divided into motor, vocal tic. Tic disorder belongs to pediatic psychosomatic disease. In four clinical cases, patients between the age of 6 to 15 consisted of three males and one females. They all are the eldest or only son and have the parental behavioral, home background and studing problem. The patients appealed to eye blinking in tic early stage and belong to chronic motor or vocal tic disorder or transient tic disorder without tourette's disorder. When estimated by an appraisal standard of Yale Global Tic Severity Scale(YGTSS). Four patients administered Bosimgeunatang known to invigorating the heart, relieving mental stress improved.

We prepared orthorhombic $LiMnO_2$ by emulsion drying method. The thermo-gravimetric measurement and X-ray diffraction studies indicated that the orthorhombic $LiMnO_2$ phase was formed above $800^{\circ}C$ by oxygen evaporation process from $LiMn_2O_4$ and $Li_2MnO_3$. In this process, we could control the ordering of $LiMnO_2$ with heating rate. It was observed that electrochemical properties depended on the ordering of this material; the ordered one exhibited good capacity retention, whereas the disordered one suffered capacity fading upon cycling, especially in the 3 V region. Transmission electron microscopic (TEM) study showed that this difference is related with difference in the stress relieving effects in the samples.

Purpose: This study was done to analyze subjectivity of smoking among adult smokers. Method: Q-methodology which provides a scientific method on subjectivity, was used. Result: Five types of smoking among adult smoker were identified Type I, Concerning Significant Others; Type II, Pursuing Psychological Comfort; Type III, Habitual Craving; Type IV, Pursuing Social Relations and Type V, Maintaining Self Control. Stage of change and methods of stress relieving were revealed to be factors influencing the smoking modes among the adult smokers. Conclusion: The five types of smoking and factors influencing them as revealed in this study provide a better understanding of smokers. Smoking styles and subjective values about smoking provide insight for nursing interventions for smoking.

The procedure on the design of a new tungsten cabide throw-away cutting tool system for deep grooving or cut-off machining is suggested. For relieving the maximum stress level at the corner radius of the blade holder, the finite element method is used. Also the pulling test device is proposed for measuring the holding force of the insert between the blade holder and the insert considering the materials in contact and configuration parameters of the holder.

Non-alloyed and 1.0%Ni alloyed ductile cast iron were cast into the sand mold and metal mold, and finer graphite size was obtained in case of metal mold casting. Direct tempering after casting showed the slight increase of absorbed energy, which is largely due to the relieving of residual stress that is developed during casting. After austempering heat treatment, higher impact energy was obtained in case of metal mold casting than sand mold casting, which is due to the finer graphite size.

A literature study was progressed for oriental medical diagnosis and treatment for Jianwang(健忘) : forgetfulness(amnesia). In orental medicine, the reason of Jianwang(健忘) was congenital insufficiency(稟賦不足), meditational excessiveness(思慮過多), deficiency of heart(心虛), phlegm retention(痰飮), deficiency of kidney(腎裏), breakdown of the normal physiological coordination between the heart and the kidney(心腎不交), blood stasis(瘀血). The method of medical treatment was invigorating vital energy and enriching the blood(大補氣血), invigorating the heart and nourishing blood(補心養血), dissipating phlegm and relieving mental stress(化痰寧神), regulating the spleen corresponds to earth(理脾土), invigorating the heart and the kidney(補心腎), reinforcing the liver and the kidney(培肝腎), promoting blood circulation to remove blood stasis(活血祛瘀) and etc. Herbal medication was followed as those method. The prescription was commonly used as Guibitang(歸脾湯), Insuksan(仁熟散), Chunwangbosimdan(天王補心丹), Susunghwan(壽星丸), Samjohwan(蔘棗丸) and etc.

Innovative SMC with low iron loss was made from iron powders with evaporated MgO insulation coating. The coating had greater heat-resistance than conventional phosphatic insulation coating, which enabled stress relieving annealing at higher temperature. Magnetic properties of toroidal samples (OD35mm,ID25mm, t5) were examined. The iron loss at 50Hz for Bm = 1.5T was lower 50% of conventional SMC and was almost the same with silicon iron laminations(t0.35). It became clear that MgO insulation coating has enough heat resistance and adhesiveness to powdersurface to obtain innovative SMC with low iron loss.

Steroid and local anesthetics were injected into the epidural space through the posterior sacral foramen or lumbar approach in 4 patients for the purposes of relieving severe low back pain and radiculopathy. These patients were referred from other sections dealing with low back pain and radiculopathy, because one could not tolerate the surgical stress due to a heart problem, another two did not want the operation and the last had post-laminectomy status. All patients were satisfied with the results subjectively.
