When therapeutic irradiation is indicated for the orbital tumors, the greatest concern is the risk of radiation-induced cataract. Conjunctival lymphoma is one of the good examples. We would like to report the procedure of the lens shielding device(L.S.D) and the result of irradiated dose to the lens. L.S.D. consistes of two parts : load alloy to attenuate electron beam, and dental acryl which completely covers the lead alloy to avoid discomfort of cornea from contacting directly with cerrobend and side scattering by cerrobend. And for easy location and removal, side bars were made on each side. Radiation doses were meaured with TLD(TLD 3500 Hawshaw). Markus chamber in a polystyrene phantom. The phantom was irradiated with 9MeV electron beams from Clinac 2100C with $6{\times}6cm$ electron cone. The relative dose at 6mm depth where the lens is located was $4.2\%$ with TLD and $5.1\%$ with Markus chamber clinically when 2600 cGy are irradiated to the eyeball, the mapinary dose to the lens will be 109 cGy or 132 cGy, which will significently reduce the cataract.

Fungus ball of the paranasal sinuses is usually found in only one sinus, most frequently in the maxillary sinus. It may produce symptoms of chronic rhinosinusitis, such as purulent rhinorrhea, nasal obstruction, headaches, and sensation of pressure. However, cases involving bilateral paranasal sinuses are rarely reported. Herein we report two cases of fungus ball in bilateral paranasal sinuses with a review of this disease entity.

The algorithms and guidelines are a synthesis of current scientific evidences with clinical issues of safety and tolerability. It is inevitable that pharmacological strategies of psychiatric treatment have to be based on evidence-based medicine. The first Korean Medication Algorithm for Bipolar Disorder was developed from the information and opinions gathered by wide surveys to Korean psychiatrists and then, in the first time, its feasibility study was done. The problems on appropriateness of the shift of step, full education of algorithm administration and procedure before implementation, and easy applicability of measuring scales were found. These problems must be fully considered for algorithm implementation in the near future. Rapid updates on new evidences of therapeutic effects of drugs and recent trends of diagnostic concepts about bipolar disorder may justify revision of the medication algorithm. Especially, addition of widespread use of novel antipsychotics in all phases of illness, evidences of new anticonvulsants' effects, and change of strategies in the acute depression and maintenance treatments will have to be considered. Moreover, modification of questionnaire for algorithm revision will be needed in the aspect of easy implementation.
