Pesquisador Virtual: solución informática para la detección de casos sospechosos de COVID-19 / Pesquisador Virtual: IT solution for the detection of suspected COVID-19 cases

Se presenta el Pesquisador Virtual, solución informática desarrollada por la Universidad de las Ciencias Informáticas (UCI) en colaboración con el Ministerio de Salud Pública (MINSAP), que mediante encuestas permite captar información del estado de salud (síntomas y padecimientos) de la población, como complemento al proceso de pesquisa activa, en el marco del enfrentamiento epidemiológico a la pandemia COVID-19. Para la realización de la encuesta se cuenta con una solución móvil y una solución Web. El resultado de la encuesta (información estadística y nominal) es monitorizada en tiempo real mediante gráficos y estadísticas por las diferentes instancias del MINSAP, tanto a nivel nacional como provincial y municipal, mostrando reportes personalizados según el nivel de acceso en dependencia del nivel del organismo. Con esta información, diferentes instancias del sistema de Salud actúan de manera inmediata, sobre todo la atención primaria de salud (APS), para evitar la propagación de la epidemia y la atención temprana de posibles contagiados(AU)

A mobile and Web solutions are available for the presentation of the survey. The results of the survey (statistical and nominal information) are monitored in real time through graphics and statistics by the different MINSAP structures at the national, provincial and municipal levels, with variable access depending on the level of the structures. With this information, different departments of the health system act immediately, especially Primary Health Care (APS), to prevent the spread of the epidemic and to provide early care for those who may be infected(AU)

Development and Evaluation of a Web-based Computer-Assisted Personal Interview System (CAPIS) for Open-ended Dietary Assessments among Koreans

The accuracy of dietary assessments has emerged as a major concern in nutritional epidemiology and new dietary assessment tools using computer technology to increase accuracy have been developed in many countries. The purpose of this study was to develop a web-based computer-assisted personal interview system (CAPIS) for conducting dietary assessment and to evaluate its practical utilization among Koreans. The client software was developed using Microsoft's ClickOnce technology, which allows communication with a database system via an http server to add or retrieve data. The system consists of a tracking system for the subject and researcher, a data-input system during the interview, a calculation system for estimating food and nutrient intake, a data-output system for presenting the results, and an evaluation system for assessing the adequacy of nutrient and food intake. Databases of the nutrient composition of common food (n = 3,642), recipes for common dishes (n = 1,886), and photos of serving sizes for food and dishes (n = 4,152) were constructed, and logical processes for data collection, calculation, and output were developed. The functionality, on-site applicability, and efficiency of CAPIS were evaluated in a convenience sample of 181 participants (61 males, 120 females; aged 24 to 85) by comparing with manual 24 hour recall method with paper questionnaire. The CAPIS was functioned adequately in the field survey in terms of completeness of function, security, and compliance of researcher and subjects. Regarding on-site applicability, 23.2%, 32.6%, 35.4%, and 43.7% of subjects reported that CAPIS was easier to recall their diet, to estimate the amount consumed, to communicate with the interviewer, and to concentrate on the interview than the manual method with paper questionnaire, respectively. Although CAPIS required more interview time (9 min 42 sec) compared to the manual method (7 min 30 sec), it saved time and cost for data coding and entry (15 min 35 sec) and gave high satisfaction from the prompt feedback after interview to the subjects, which increase efficiency to apply on the field survey. Our results suggest that the newly developed CAPIS is suitable for conducting personal interviews for dietary assessment in Korean population.

Computer-aided Diagnosis for Lung Cancer

Lung cancer is a leading cause of cancer death in the developed countries and the key to improving cancer prognosis is diagnosis at an early stage. For this reason, lung cancer screening using low-dose, multi-channel computed tomography (LDCT screening) is becoming popular in theses days. LDCT screening causes large amount of datasets to be interpreted and CAD has an advantage for the interpretation of large amount of images without fatigue or variation. Therefore, CAD can be used for diagnosis of lung cancer as a second reader for the detection, characterization of pulmonary nodules, evaluation of volume and changes on follow-up examination. It is important to verify the performance of CAD program based on large and reliable datasets

The new approach to maxillary and mandibular anterior dental arch forms: The prediction to maxillary and mandibular anterior occlusal relationship by computer program / 대한치과교정학회지

When we deal with maxillary and mandibular anterior dental arches showing problems in occlusal relation and aesthetics caused by malformations of teeth and congenital missing, et al during the orthodontic treatment, we could not often decide the functional occlusion by only relying on the orthodontic treatment. If orthodontists can predict what kinds of treatments are needed for functional occlusion in maxillary and mandibular anterior dental arches, they can not only effectively treat patients but also facilitate the cooperation with other field during the treatment. Our previous research showed the correlation among intercanine width, segment depth and arch perimeter by using the Korean normal occlusion model. At this time, we produced the computer application program by taking advantage of this correlation. And then, we applied this program to setting up the treatment plans for 2 patients with the damaged maxillary and mandibular dentures. With the help of this program, we could not only easily acquire the information about the change of variables required by treatment plans but also understand the change of the anterior dental occlusion corresponding to the change of each variables such as the intercanine width, segment depth and arch perimeter. Later, if we can have the information about the relationship between the change of the angle of incisors depending on facial types and arch forms and, in addition, can acquire the appropriate intercanine width, we can have the ability to produce the 3 dimensional occlusogram for the anterior dental arch forms.
