Analysis of multifrequency impedance of biologic active points using a dry electrode system.

Objectives: A system is being developed for measurement of biologic active points (BAPs) in humans using a modified dry electrode. The BAPs measuring system analyzed the electrical characteristics and searched for the position of BAPs using modified dry electrodes.

Subjects: Skin electrical resistance at BAPs and non-BAPs was examined with a modified electrode system for healthy male subjects (ages 21-40).

A hybrid decision support model to discover informative knowledge in diagnosing acute appendicitis.

Background: The aim of this study is to develop a simple and reliable hybrid decision support model by combining statistical analysis and decision tree algorithms to ensure high accuracy of early diagnosis in patients with suspected acute appendicitis and to identify useful decision rules.

Methods: We enrolled 326 patients who attended an emergency medical center complaining mainly of acute abdominal pain. Statistical analysis approaches were used as a feature selection process in the design of decision support models, including the Chi-square test, Fisher's exact test, the Mann-Whitney U-test (p < 0.

Implementation of Chest X-ray Observation Report Entry System.

Objectives: X-rays are widely used in medical examinations. In particular, chest X-rays are the most frequent imaging test. However, observations are usually recorded in a free-text format.

Support Vector Regression-based Model to Analyze Prognosis of Infants with Congenital Muscular Torticollis.

Objectives: Congenital muscular torticollis, a common disorder that refers to the shortening of the sternocleidomastoid in infants, is sensitive to correction through physical therapy when treated early. If physical therapy is unsuccessful, surgery is required. In this study, we developed a support vector regression model for congenital muscular torticollis to investigate the prognosis of the physical therapy treatent in infants.

A new method for non-invasive measurement of skin in the low frequency range.

Objectives: The purpose of our study was to estimate skin structure and conductivity distribution in a cross section of local tissue using non-invasive measurement of impedance data. The present study was designed to evaluate the efficiency of skin depth information through computer simulations. The multilayer tissue model was composed of epidermis, dermis tissues, and subcutaneous.
