A meta-analysis of studies was conducted on the validity of the Structured Clinical Interview for DSM (SCID) as diagnostic tools for the detection of psychiatric disorders: Schizophrenia, Bipolar disorder, major depressive disorder and Substance-related disorders. Looking at sensitivity and specificity, the SCID is seen to perform well, with to high values for all four diagnosis included in the study. In general, SCID was better used in detecting thrue negatives or the non-cases, as shown in higher specificities as compared to sensitivities.

Nowadays, abdominal ultrasound (US) was used widely in the annually health checkup. It can detect some diseases in the presymptom period as effectively as looking for cancer early, e.g. the breast cancer US screening on over 30 year- old Asian women was very reliable. From January 1998 to November 1998, we performed the abdomen and breast US examination for 21,558 workers in 97 factories in the annually health checkup programs (included 17,547 cases of abdominal US and 4,111 cases of breast US). It concluded that the abdomen and breast ultrasonic screening examinations would be useful in the patients without symptoms

IAEA's guidance levels have been provided for western people to the end. Guidance levels lower than the IAEA'S will be necessary in view of Korean people's proportions. Therefore, we need to develope the standard doses for Korean people. And we conducted a nationwide survey of patient dose from x-ray examinations in Korea. In this study, the 278 institutions were selected from Members Book of Korean Hospital Association. The valid response rate was approximately 57.9%. Doses were calculated from the questionnaires by NDD method. We obtained the results were as follows; 1) General radiographic equipments were distributed for 42.0%, fluoroscopic equipments 29.4%, dental equipments 13.2%, CT units 8.1% and mamographic units 7.2%. 2) According to classification by rectification, three-phase equipments were 29.9%, inverter-type generators 29.5%, single-phase equipments 25.5%, constant voltage units 9.0% and unknown units 6.0%. 3) According to classification by receptor system, film-screen types were 46.8%, CR types 26.8%, DR types 17.7% and unknown types 8.9%. 4) The number of examinations were chest 49.2%, spine 16.8% and abdomen 12.7%. 5) Patient doses were head AP 3.44 mGy, abdomen AP 4.25 mGy and chest PA 0.39 mGy.
