The Primary goal of this research is to verify the usefulness of Aster Koraiensis as a garden plant and to figure out the appropriate planting space which would bring the most effective results in terms of scenery and cost. For these purpose, we gathered the saplings of the wild grown Aster koraiensis in August and maintained them for winter. The following spring, we planted them in flat bare land with 3 different panting spaces of 50 x 50Cm, 40x30Cm, 30x30Cm. 2nd years after planting, we observed and compared the 3 different columns on the status of growth, number and size of leaves and conditions of flowering. The results are as follows : The number of leaves, stalks and roots of individual plants were increased by the wider planting density. But the ratio of leaf area per unit area appeared to be the highest in the 40X30cm sector which showed 366.9%, while the 50x50cm column showed 294.1% and 360.4% in the 30X30cm column. As for the conditions of flowering, such as the size of flowers, the number of petals per blossom and the length of flowerstalks, the best results were observed in the 50x50cm column. On the other hand, the 40x30cm column yielded the largest number of blossoms per unit area. On the basis of these results, we could induce that the 30x30cm column had already passed the peak point for the best scenery within 2 years after planting, while the 50x50cm column had not yet reached the peak point. Naturally, this leads to the conclusion that the 40x40cm planting space could be most effective when we assume the peak period for scenery to be 2nd years after planting. According to our investigation, the blooming period of Aster Koraiensis in the central region of the Korean peninsular lasts about 70 days from 15th June to 25th August. And the peak blooming time is 30 days from 5th July to 5th August. On the basis of these findings, we can reach the final conclusion that Aster Koraiensis has many merits and is useful as ornamental flavor of garden.

Thunderclap headache is a hyperacute, severe headache that is so named because the pain strikes suddenly and severely, and is sometimes a sign of a medical emergency. We report a case of pheochromocytoma in the urinary bladder in a 48-year-old woman who presented with recurrent thunderclap headache after voiding and exercise. So we think thunderclap headache during or immediately after micturition may be an important diagnostic clue of bladder pheochromocytoma.

The author made calvarial defects of different sizes in rat to study the effect of defect size on healing process. Experimental animals were sacrified at 3 days, 1 week, 2, 4, 6 weeks. The specimens were examed under light microscope with Hematoxlin-Eosin and modified Gomori's trichrome stain, and under fluorescent microscope after glinding the specimens. The results were as follows. 1. 4㎜-diameter calvarial defects healed about 70% after 6 weeks. 2. Lamellated bone trabecules were seen in 6㎜-diameter calvarial defects after 4 weeks, and the small specules of bone and marrows were observed after 6 weeks. 3. 10㎜-diameters calvarial defects healed about 50% and incomplete interconnection of the lamellated bone trabecules were observed after 6 weeks. 4. Under fluorescent microscope, about 4㎜-long bone regeneration could be seen in most of the defects.

The author investigated the 9693 medico-legal autopsied cases that performed at National Institute of Scientific Investigation from 1975 to 1984 to provide the basic statistical problems of infectious diseases as cause of death. So, the following conclusions were obtained from 700 cases of infectious diseases. 1. 700 deaths (9.6%) of the total 9693 medico-legal autopsied cases were occured by infectious diseases. 2. Male to female ratio of death from infectous diseases was about 2 : 1. 3. The highest incidence of age was less than 9 years old, and then 3rd, 4th, 5th, 2nd and 6th decades in frequency. 4. The highest incidence of system involvement of infectious diseases was respiratory tract (55.7%), and then gastrointestinal tract (19.4%), cardiovascular system (8.5%), septicemia (8.1%) and central nervous system (6.9%) in order. 5. Peneumonia, pulmonary tuberculosis, panperitonitis, septicemia, interstitial myocarditis and meningitis in frequency were the common causes of death from infectious diseases.

As crops recently can be cultivated all the year in greenhouses, we need to improve the environment in which crops are able to grow in the summer. Therefore, in this study, we quantitatively got the cooling effects of 4 single span plastic greenhouses in the following ways : by spraying mist or sprinkler, or by opening the side window. and with those variables, we simultaneously did experiments at 4 greenhouses under equivalent conditions to reduce the temperature of the greenhouses in the summer. The results of the experiments are as following : 1) The temperatures of the greenhouses were effectively reduced by both spraying mist and sprinkler. 2) When the mist is intermittently sprayed. the indoor temperature has decreased by 4 degrees centigrade, meanwhile, in the greenhouse to make experiments using sprinkler, the temperature of that has been reduced by 2 degrees centigrade. Therefore, we can see the cooling effects of smaller mist in size as more effective than those of sprinkler. 3) When the greenhouse is naturally ventilated by opening the side window, we have to apply another cooling system because the indoor temperature is higher than the outdoor one.

Consolidated financial statements are drawn out for reporting the result of operations and the fiancial postion of a parent company and its subsidiaries to their users. The requirements of consolidated financial statements are as follows; (1) They can aquire a vertical accounting information about the parent company and its subsidiaries. (2) They can protect the manipulation occurred by using the internal transaction between the parent company and its subsidiaries. (3) They can be possible for the adaptation of the consolidated income tax return. In the decision of the area of consoldation in consolidated financial statements equity standards and substantial control standards are generally being used. From the theoritical point of view the latter is more appropriate. But actually equity satandards must be applied unless the objective criteria are provided. Among the regulations about the unconsolidated subsidiaries in our own rule of consolidated financial statements foreign subsidiaries, small scale subsidiaries, and business of character different will have to be flexible rather than an uniform rule. In the valuation of the investment accounts, cost method and epuity method are generally applied. In the case of consolidated company, no probleme will occur because of the same results form any methods. But in the case of the unconsolidated company and the associated company, the application of the equity method would be effective.

Estimation problems of parameters of the failure process and the repair effect in repairable systems are considered. We propose estimation procedures in repairable systems without preventive maintenances. The fallure process is modeled by a proportional age reduction model (Brown. Mahoney, Sivazlian [5]) which is able to consider both aging and repair effects. Maximum likelihood method is used to estimate the repair effect and parameters of intensity function simultaneously. Simulations are performed to evaluate the accuracy of estimators. A numerical example is also presented.

There is nothing to sermon the S'u-nya except the Buddhism in the world thoughts. In this point Buddhism has its original character any other thoughts nerver have not. Therefore we can say that S'u-onya makes Buddhism more Buddhism. This paper deals with the problem of 'Reality' from early Buddhism to early Maha-ya-na Buddism through the S'u-nya. That is, S'u-nyata- and ana-tmava-das(Naira-tmyava-da) of early Buddhism is transformed into the theory of elements in the Sarva-stiva-da. That is deviated from the fundamental teachings of Buddha. Opposite to this position some criticism is araised. This is very the Pudgala Naira-tmya·Dharma Naira-tmya of prajna-paramit-su-tra. S'u-nyata- as above thoughts is systematically established by Na-ga-rjuna. This paper is developing historically the series of thoughts as above through the ReaUty(Being) and S'u-nya.
