Korea and the U.S. come to a settlement on Free Trade Agreement. The FTA will include investment chapter which is similar to the NAFTA investment chapter. The NAFTA investment chapter provides investors with strong investment protection and an arbitration mechanism to resolve disputes between an investor and the state. Since it was combined with FTA in the NAFTA, it has construed one of the most powerful mechanism to enforce provisions of investment agreements and to protect transnational capitals. This paper studies on the NAFTA investment dispute cases and considers their policy implications for Korea. Korea government has to increase its ability to manage the investor-state disputes effectively.

The author observed 68 cases of the tympanic membrane perforation, who visited at the Department of Otolaryngology of Capital Armed Forces General Hospital in 1983. The results obtained were as follows; 1. The symptoms were hearing loss 56 cases(82.4%), tinnitus 50 cases(73.5%), otalgia 48 cases(70.6%), autophonia 40 cases (58.8%) in order. 2. The duration from tympanic membrane perforation to confirmation at OPD was usually within 3 days(44 cases, 64.8%). 3. The side of tympanic membrane perforated ear was usually left side in 50 cases(73.5%). 4. The location of tympanic membrane perforation was usually seen in the anteroinferior quadrant(28 cases, 41.2%) and intermediate portion (36 cases, 53.0%), and the shape of tympanic membrane perforation usually showed triangular shape(43 cases, 63.2%), and the triangular shape was about 25.5 ㏈ in air-bone gap. 5. The air-bone gap after tympanic membrane perforation was usually about 11-20 ㏈(30cases, 44.1%). 6. As nonhealing 5 cases of nonhealing tympanic membrane perforation 6 cases (8.8%) occurred within the patients of the nasal problem (12 cases) in relationship between Eustachian tube and the neighboring organs, the Eustachian tube was influenced by the diseases of the neighboring organs with symptoms (maxillary sinus and intranasal structures), and the function of Eustachian tube was disturbed, thereby the healing of tympanic membrane perforation was delayed. 7. In 44 cases visited at out patient department in 3rd day from tympanic membrane perforation, it usually occurred the transformation for the shape of tympanic membrane perforation that the triangular shape was transformed to irregular round, and the irregular round was changed to round. And the healing duration of tympanic membrane perforation was mostly closed in 10 weeks.

It is essential to operate chemical lasers with supersonic ejector system as the laser output power goes up. In this research, ejector design parameter study was carried out for optimal ejector design through understanding the ejector characteristics and design requirements for chemical lasers operating. Designed ejector was 3D annular type with 2$^{nd}$ -throat geometry and pressurized air was used for primary flow. Ejector design was carried out with two steps, quasi-1D gas dynamics was used for first design and commercial code was used to verify the first design. In this study, to get the effect of ejector geometry on its performance, three cases of primary nozzle area ratio and 2$^{nd}$ -throat cross sectional area and two cases of 2$^{nd}$ -throat L/D ratio experiments were carried out. Primary and secondary pressures were measured to get the mass flow rate ratio, minimum secondary pressure, ejector starting pressure and unstarting pressure at every case. In the result, better performance than design level was shown and optimal ejector design method for chemical lasers was obtained.

Spontaneous intracerebral hemorrhage is one of the most devastating forms of cerebrovascular disease in the field of neurosurgery, and is most frequently associated with the hypertension in the distribution of the penetrating yessels, or can be secondary to other factors, like aneurysm, arteriovenous malformation, glial tumor, metastasis, infarction, anticoagulation therapy, coagulation disorders such as leukemia or thrombocytopenia. Although many cases of recurrent hypertensive intracerebral hemorrhage have been reported, bilateral simultaneous hemorrhage has not been reported. The authors report a case of bilateral simultaneous hypertensive intracerebral hemorrhage in a 62-year-old male, which was treated by conservative management.

It has been well known that respiratory status has affected the intracranial pressure by' changing the brain blood flow, and also ethanol has affected the respiratory system by inhibiting the respiratory center and has affected cardiovascular system by inhibiting the cardiac performance and decreasing the total peripheral resistance. However, effect of ethanol on intracranial pressure has not been studied satisfactorily. Thus, following experiment was performed to examine the change of the intracranial pressure after ethanol administration in the cats. Ethanol was infused intravenously by lg ethanol per kg body weight for 15 minutes. Intracranial pressure was measured through balloon inserted between epidura and skull. Arterial blood pH, Po_2, Pco_2, ethanol concentration were measured. The results obtained are surnmerized as follows. Blood ethanol concentration increased by linear and peaked at 15 minutes(blood ethanol concentration was 409±31 mg%). Po_2, Pco_2. and pH at 15 minutes were 80. 3±5. lmmHg, 49.2±3.3mmHg and 7.24 =0.015 respectively. Blood pressure began to decrease and arterial pulse pressure began to increase at 10 minutes and more and more at 15 minutes respectively. Intracranial pressure began to increase at 10 minutes (blood ethanol concentration was 316±33 mg%) and peaked as 168.7±11.4% contrast to control at 15 minutes and also amplitude of intracranial pulse wave was increased. From the above results, it was suggested that intracranial presssure and amplitude of intracranial pulse wave were increased significantly by inhibiting respiratory center and thereby dilatating cerebral blood vessels with intravenous ethanol administration.
