A metal sheath provides a cable with electrostatic screening and a degree of magnetic screening. The presence of a screen on a cable also reduces the induction arising from the high-frequency components of transients caused by power-line switching and also induced transients from lightning strokes; such transient induced voltages are of increasing importance with the increasing use of miniaturized telecommunication equipment with very small thermal capacity. This paper describes electrostatic induction and electromagnetic induction caused by power interference. Also screening factors are proposed.

Background: Today, survival rate of patients with chronic renal failure/hemodialysis has increased so that chronic illnesses are more likely to occur. Cancer is the main cause of morbidity and mortality in such patients. Aim: In this study, physician attitudes were examined about cancer screening in patients with renal failure. Materials and Methods: This study was done by face to face questionnaire in the $27^{th}$ National Nephrology Congress to determine if the physicians dealing with chronic renal failure, hemodialysis or renal transplanted patients, recommend cancer screening or not and the methods of screening for cervix, prostate, breast and colon cancer. Results: One hundred and fifty six physicians were included in the survey. A total of 105 (67%) participants were male and the age of responders was $48{\pm}9$ years. About 29% were specialists in nephrology, 28% internal medicine, and 5% were other areas of expertise. Some 48% of participants were hemodialysis certified general practitioners. Patients were grouped as compensated chronic renal failure, hemodialysis or renal transplanted. Of the 156 responders, 128 (82%) physicians recommended breast cancer screening and the most recommended subgroup was hemodialysis patients (15%). The most preferred methods of screening were combinations of mammography, self breast examination and physicianbreast examination. 112 (72%) physicians recommended cervix cancer screening, and the most preferred method of screening was pap-smear. Colon cancer screening was recommended by 102 (65%) physicians and prostate screening by 109 (70%) physicians. The most preferred methods of screening were fecal occult blood test and PSA plus rectal digital test, respectively. Conclusions: It is not obvious whether cancer screening in renal failure patients is different from the rest of society. There is a variety of screening methods. An answer can be found to these questions as a result of studies by a common follow-up protocol and cooperation of nephrologists and oncologists.

Objective : To analyze the factors affecting the participation rate in the health screening program of medical insurance. Method : We investigated the factors associated with the participation rate in the health screening program in Korea. Data were collected at the aggregate level from 145 employee health insurance societies and 227 self-employed health insurance societies from 1995 to 1997 Data were also collected at the individual level from four health insurance societies. This study hypothesized that the participation rate of the health screening program was related to 1) the characteristics of its members and the size of the health insurance society; 2) the specifications of the health screening program; 3) the venue of the health screening institution and the interests of individuals in the health screening program; and 4) the activities of the health insurance society. We used bivariate and multiple regression models to examine the factors on the participation rate of the health screening program. Results : First, in the case of dependents of on employee health insurance society, the ratio of dependents 40 years old and over, the average monthly contribution per household, the interest and satisfaction level of individuals in health screening, and the level of refunds for over-payment were all associated with the participation rate in the health screening program, accounting for 54.4% of the participation rate. Second, in case of those insured by the self-employed health insurance society, the interest and satisfaction level of individuals in health screening, the level of refunds for over-payment, and the performance level of on-the-spot health screening were statistically significant, accounting for 40.1% of the participation rate. Conclusion : The factors concerning the participation rate in the health screening program of medical insurance, in both a health insurance society and for individuals, were closely related to the age and gender of individuals and household contributions.

The Antioxidant activity screening identification of five kind compounds in Artemisiae annuae herba with the on-line screening high performance liquid chromatography (HPLC) $ABTS^+$ assay. The various experimental variables such as the extraction time (h) and extraction solvent composition (%) of dipping method were investigated efficiently extraction at the room temperature $25^{\circ}C$. The results, the highest yield of total extract amount (0.458 g, 15.250%) was obtained by dipping method with 100% water and extraction time to 3 h. And the on-line screening HPLC-$ABTS^+$ assay method was rapid and efficient to search for bioactivity from natural products.
