On the whole, the major impetus for the institutionalization of public hygiene in Korea came from two directions. On one hand, the self-enlightened intellectuals had introduced a variety of Western ideas and theories on public hygiene since the mid-eighteenth century. On the other hand, Japan strongly influenced the modern systems of Korean health care and medical education, especially through Japanese efforts at the sanitary control of infectious diseases such as smallpox and cholera. The institutionalization of Korea's public hygiene in this period corresponded not to the high ideas of the progressive intellectuals but to the larger social and institutional changes caused by the major political events. Ideas of public hygiene were institutionalized as a powerful strategy of linking the imperial capital and colonial domains.

To investigate MR artifacts induced by metallic implants, scans were obtained using both the ferromagnetic Drake lip and the non ferromagnetic Yasargil clip. Scan were taken through the area of clips using geometrical phantom. The MRI was performed by spin echo technique and gradient echo technique on both 2.0T and 0.5T MR unit. The luthors evaluated the nature and differences of artifacts in each sequence and parameter. Artifacts induced by both lips were noted in the direction of frequency encoding gradient, and consisted of region of signal loss abutted in one side by survilinear region of bright signal. Geometric distortion of image was marked in the Drake clip, out was minimal in the Yasargil clip under both 2.0T and 0.5T. Artifacts were more pronounced in the gradient echo technique than those of the spin echo technique on both 2.0T and 0.5T. Although there were no differences n the nature of artifacts induced by the Drake clip among each parameter in the spin echo technique under 2.0T, artifacts were slightly more pronounced on T2 weighted image under the 0.5T field, but no differences were found in the nature of artifacts induced by the Yasargil clip in the spin echo technique under, both the 2.0T and 0.5T fields. Marked artifacts were induced through the small area of the Drake clip which were included in the scan plane, but induced artifacts were small when a small area of the Yasargil clip was included in the scan plane. It seemed likely hat artifacts were slightly more pronounced in the 2.0T than the 0.5T field in both clips, but objective evaluation of the difference was difficult, In conclusion, these results can be an essential basis for the interpretation of MR images or patents with metallic inplants.

2 Cases of primary lymphoma of brain are reported with brief review of literatures. Preoperative CT scans were performed and the correct diagnoses were made by operative biopsy. Initially the tumor masses were located in the periventricular white matter, in both cases. CT scans showed slightly high density areas with homogenous contrast enhancement. After local irradiation, these lesions disappeared completely. But soon after, well circumscribed homogenous contrast enhancing mass lesions recurred in the cerebellum.

Thirty-six patients (24 with oral cavity or oropharynx cancers and 12 larynx cancers) were prospectively examined with computed tomography (CT) to determine its value in staging the primary tumor and to compare with the clinical staging. The CT staging agreed with the clinical staging in 50% (12/24) of the oral cavity or oropharynx cancers and in 67% (8/12) of the larynx cancers. The CT upgraded the clinical staging in 29% (7/24) of the oral cavity or oropharynx tumors and in 33% (4/12) of the larynx cancers, whereas the CT downgraded the clinical staging in 21 % (5/24) of the oral cavity or oropharynx cancers. There is no downgrade on CT in larynx cancer. The post-surgical confirmation was not made in most of the cases. The possible causes of disagreement between the CT and the clinical staging, and the diagnostic value of the CT in evaluation of the primary tumor in oral cavity, oropharynx and larynx were discussed.

Eighty-eight patients who presented with a variety of head and neck symptoms were examined with intravenous oritraarterial digital subtraction angiography (IV or IA DSA), using the DSA equipment developed by Seoul NationalUniversity Hospital. A grading system was used to evaluate the ability of DSA to answer specific diagnsoticquestions. Diagnostic information without need of further study was obtained in 71% with IV DSA, in 86% withaortic arch DSA and in 81% with selective arterial DSA, showing a total of 79% of diagnostic accuracy with DSA. Itis concluded that IV DSA is useful in the evaluation of the cervical carotid and vertebral arterial disease, andpituitary mass lesion, while IA DSA is useful in the evaluation of the cervical carotid and vertebral arterialdisease, and pituitary mass lesion, while IA DSA is useful in the evaluation of most of the intracranial lesions,spinal arteriography and intra-arterial embolization. DSA is both an accurate and safe imaging modality in thestudy of head and neck diseases.

From August, 1981 to November, 19S5, the Hoffmann and Monofixateur apparatus were employed in the treatment of thirty five open tibial fractures that we considered to have a poor prognosis with more conventional forms of treatment. The results were obtained as follows; l. Application of Monofixateur was minimum iatrogenic soft tissue injuries and easier, simpler than Hoffmann and two external fixators were favorable device with rigidity in wound management. 2. Two external fixators could obtained sufficient stability when 3 or more pins were applied at each fragment of fracture in Hoffmann and 2 or more pins in Monofixateur. Monofixateur could obtained high stability with small number of fixation components and more stronger against anterior-posterior bending and in Hoffmann more stronger against lateral bending. 3. External components of Monofixteur was located in anterior surface, therefore dynamization converted tensile force of anterior surface of tibia to compression force and then bone union was activated. 4. After operation, in Hoffmann correction of compression, distraction and angular, rotational deformity were possible and in Monofixateur correction of compression distraction, and anterior or posterior angulation was possible. 5. Because of rigid stability of two external Bxators, these allowed early movement, avoiding joint stiffness and duration ambulation unilateral assembly of device in position biomechanically favorable. 6. The lateral view of fracture site could not be confirmed accurately due to overlapping of Hoffmann's adjustable connecting rod and bony shadow. In Monofixateur A-P and lateral view of Fx. site could be confirmed. 7. Accurate reduction and compression played a important role in bone union. 8. The time to fixation for all of the fractures averaged 20 weeks in Hoffmann and 16 weeks in Monofixateur. The time to union averaged 24 weeks in Hoffmann and 20 weeks in Monofixateur.
