This experiment was carried out as a part of the studies on reasonable application of nitrogen in rice plant to determine: (Ⅰ) Nitrogen absorption. and rooting of rice seedlings as affected by urea foliar application at late seedling stage (Ⅱ) Effect of leaf prunning and foliar application of urea at late heading stage on the maturation and yield of rice (Ⅲ) Effect of foliar application of urea and its time during the stage of ear formation on yield of rice plant. Results obtained are summarized as follows. Exp.I: Nitrogen absorption and rooting of rice seedlings as affected be urea foliar application at late seedling stage. 1 : The foliar application of urea plots(T₁,T₂) snowed mare N-content than non-urea foliar application plot(T0) at lane seedling stage, being significant among treatments and foliar application of urea seemed more effective in increasing the N-content of seedlings. and promoted root settlement and early growth alter the transplanting. 2 : The carbon contents of the plants of T₁, and T₂ at late seedling stage increased than T_0, and the carbon contents. of T₁ and T₂ plots became higher in amount in proportion to the nitrogen absorption as compared with those of T0. 3 : C/N ratio appeared significant among soil application plots(N₁, N₂) and foliar application of urea plots (T₁, T₂ and T_0). C/N ratio was lower in case of increased amount of nitrogen. The higher contents of nitrogen and carbon and lower C/N ratio resulted in the increment of root numbers and root lengths. Exp.II: Effect of leaf prunning and foliar application of urea at late heading stage on the maturation and yield of rice. 1 : There was a highly significant decrease in the maturing rate by severe leaf prunning. In the mean time, significant increase in maturing rate was observed with urea foliar application and it was found the more frequent application the more effective for higher maturing rate with a moderate significance. A correlationship between the level of prunning and maturing rate was enumerated to 0.961 of correlation coefficient, which indicated an increased maturing rate by the increased number of remaining leaves. 2 : The 1.000 grain weight, grain weight and hulled rice yield increased by leaf prunning in order (plot a$lt;b$lt;c$lt;d$lt;e) at the plots where upper single(a), two(b), three(c), four(d) and five leaves(e) remained, respectively, as compared with control plot(f), thus the high significance were observed among the leaf prunning. Correlation coefficient(r) of 0.925, 0.971 and 0.989, respectively, showed highly significant corrlationship between the level of leaf prunning. In the mean time, the 1000 grain weight, gram weight and hulled rice yield increased in oder at one time urea foliar application plot(B) and two times foliar application plot (A) as compared with the .yield of control plot (C), and the high significance were observed among those treatments. Hulling ratio also showed the same tendency among those treatments(C,B and A plots in order). 3 : The nitrogen and carbon contents of both panicles and leaves in the foliar application of urea were increased. C/N ratio showed a higher level only in the leaves at the urea spray plot. In the mean time, it was found a higher degree of correlationship between the hulled rice yield(0.937),the contents of nitrogen(0.952) and carbon(0.946), and C/N ratio, indicating that the higher the contents of nitrogen and carbon, and C/N ratio the higher the yield of hulled rice. Exp. III: Effect of foliar application of urea and its time during the stage of ear formation on yield of rice plant. 1 : The difference in average number of grains per ear was significant between the time of ear fertilization, showing a tendency of increase of grain number in accordance with earlier treatments although no significance was seen between methods of ear fertilization. Number of grain of 2.0% urea solution foliar application plot, 10% urea solution soil application plot, 2.0% urea solution soil application plot and the control are 65.9, 65.6, 64.4 and 63.9 grains, respectively, indicating the largest grain number in the 2.0% urea foliar application plot among the others. 2 : Maturing rates showed a significance between time of ear fertilization, showing a tendency of increase in the rate with the time lagging until 7 days before Baring. Those of A₁, A₃, A₂ and A_0 were 89.8%. 89,4% 87.8% and 87.5% respectively, showing the highest of rate in A₁ and A₃ in methods of ear fertilization and being highly significant between its treatment. 3 : 1000 grain weights were highly significant between time of application, showing a tendency of increase of weights with the time lagging until days before earings as that of maturing rates. High significance was recognized between methods of ear fertilization, showing the highest in A₂ 23.18 gr. 4 : Yields per 3.3㎡ were not significant between time of ear fertilization, whereas were highly significant between methods of ear fertilization. Those of A₁, A₃, A₂ and A_0 were 1.486 ㎏, 1.491 ㎏, 1.381 ㎏ and 1.328 ㎏, respectively, showing the highest in A₁ and A₃. 5 : Hulling ratios showed significant different between time of ear fertilization, showing the highest in T₂, whereas those of methods of ear fertilization were highly significant between its treatment, Those of A₁, A₃, A₂ and A_0 were 84.72%, 84.06%, 83.29%, and 82.56% respectively, showing the highest m A₂ and A₃ among others. 6 : Yields of hulled rice per 3.3 ㎡ showed significant different between time of ear fertilization, showing the highest in T₁, 1.192 ㎏. Whereas, those were highly significant between methods of ear fertilization. Those of A₁, A₃, A₂ and A_0 were 1.259 ㎏, 1.254 ㎏, 1.149 ㎏ and 1.095 ㎏, respectively, showing the highest in A₁ and A₂. 7 : Contents of nitrogen on rice plant increased in case of nitrogen application as ear fertilizer and showed that the case of urea foliar application was more effective than that of soil application, showing the increased nitrogen content of rice plant was accompanied by carbon content.

Four kinds of barley beverages and two kinds of colas were studied for their relative cariogenicity. Enamel specimens were made from four first bicuspids of one teenager. They were immersed in the beverages for two hours at 37℃, and then enamel microhardness was tested by microhardness tester. Barley beverages showed lower demineralizing potential than colas. Synthetic hydroxyapatite was demineralized by same method, and dissolved calcium concentration was measured by ion analyzer with calcium electrode using direct calibration. There was no significant difference between two beverages. Demineralized hydroxyapatite was analyzed by X-ray diffractometer, and there was also no significant difference in half width of peaks between two beverages. Spearman's rank correlation coefficient was 0.986(p<0.01) between calcium dissolution and X-ray diffractogram data in six beverages.

Cancer is a life crisis which inflicts major psychiatric symptoms and psychosocial problems upon patients and their families. Therefore all distressed patients with cancer should be appropriately treated with psychotherapy and psychotropic medication and properly referred for psychosocial care. In reIation to Psycho-Oncology, Psychiatrists constitute the first line of defense for recognizing the distress of cancer patients and family members that accompanies the diagnoses and treatment of cancer. The early diagnosis and referral of cancer patients who are distressed will lead to better satisfaction with care, fewer serious psychiatric problems, and improved health-related quality of life (HRQOL). The multi-disciplinary team, comprised of oncologists, Psychiatrists, oncology nurses, social workers, Psychologists, and clergy all agreed that mental function is a critical component as patients fight cancer, cope with treatments and deal with the uncertainty of survival. Actually mental health professionals working in the psychiatric, Psychological, and psychosocial aspects of care back up the primary oncology team in this area. This article aims to provide the essential facts needed to psychiatrists to identily and diagnose the common psychiatric disorders, to know the optimal management for them, and to solve the common psychosocial problems of cancer patients and their families in the context of their total oncologic care.

Background: The energy flow at acupuncture point is important for understanding the mechanism of acupuncture treatment. However, there are few studies on energy at acupuncture point, and related stud-ies have limitation in explaining the energy flow in all meridians. Thus, we aimed to understand the properties of electrical energy at acupuncture point in twelve meridians by measuring the biopotential at acupuncture and non-acupuncture points. Methods: For each meridian, twenty subjects were participated, and biopotential was measured at five transport points and their adjacent non-acupuncture points. In each subject, both ‘non-stimulation’ and ‘stimulation’ experiments were conducted in random order. The data were analyzed in two parts: biopo-tential variability and biopotential difference between acupuncture and non-acupuncture points. Results: The biopotential variability at acupuncture point was increased by acupuncture stimulation, and it was related to the activation of Qi flow by acupuncture stimulation. The biopotential difference between acupuncture and non-acupuncture points was formed in the direction related to the Qi flow theory, and this biopotential difference tended to decrease by acupuncture stimulation. Conclusion: The study on biopotential can provide a foundation for research on energy flow mechanism of acupuncture stimulation, and it is expected to overcome limitation of qualitative explanation in traditional medicine.
