Purpose: To develop a probability-based differential diagnosis for pediatric acute liver failure (PALF) based on age and socioeconomic status of the country of origin. Methods: Comprehensive literature search using PubMed, EMBASE, and SCOPUS databases was performed. Children 0-22 years of age who met PALF registry criteria were included. Articles included >10 children, and could not be a case report, review article, or editorial. No language filter was utilized, but an English abstract was required. Etiology of PALF, age of child, and country of origin was extracted from included articles. Results: 32 full text articles were reviewed in detail; 2,982 children were included. The top diagnosis of PALF in developed countries was acetaminophen toxicity (9.24%; 95% CredI 7.99-10.6), whereas in developing countries it was Hepatitis A (28.9%; 95% CredI 26.3-31.7). In developed countries, the leading diagnosis of PALF in children aged <1 year was metabolic disorder (17.2%; 95% CredI 10.3-25.5), whereas in developing countries it was unspecified infection (39.3%; CredI 27.6-51.8). In developed countries, the leading diagnosis in children aged >1 year was Non-A-B-C Hepatitis (8.18%; CredI 5.28-11.7), whereas in developing countries it was Hepatitis A (32.4%; CredI 28.6-36.3). Conclusion: The leading causes of PALF in children aged 0-22 years differ depending on the age and developmental status of their country of origin, suggesting that these factors must be considered in the evaluation of children with PALF.

Objectives: The aim of this review is to assess the clinical benefit of chuna for managing symptoms in chronic fatigue syndrome (CFS) Methods: We searched eligible studies from the following 11 databases with no language restriction: Pubmed, CENTRAL, Embase, CNKI, CQVIP, Wanfang, CiNii, OASIS, RISS and Koreamed. We selected randomized controlled trial (RCT), quasi-randomized controlled trial (Quasi-RCT) and controlled clinical trial (CCT) in which patients with chronic fatigue syndrome were treated with chuna. The results of the included studies were synthesized through meta-analysis, and their risk of bias were also assessed. Results: We searched 914 potentially relevant studies, and only 20 studies were selected for this systematic review. Meta-analysis showed that chuna was more effective in improving general symptoms (n=291, RR 0.19 [95% CI 0.11 to 0.32], Z=6.08, p<0.00001, I2=0%), fatigue (n=487, SMD -0.95 [95% CI -1.19 to -0.71], Z=7.76, p<0.00001, I2=37%) and sleep disorder (n=139, SMD -0.58 [95% CI -0.92 to -0.24], Z=3.36, p=0.0008, I2=0%) compared to health supplements or usual care. When chuna was used as an added intervention, it was more effective in improving general symptoms(n=729, RR 0.25 [95% CI 0.15 to 0.42], Z=5.19, p<0.00001, I2=0%) and fatigue severity alone(n=217, SMD -1.21 [95% CI -1.53 to -0.89], Z=7.45, p<0.00001, I2=15%) compared to control. Conclusion: We found that chuna was beneficial for improving severity of general symptoms and fatigue at post treatment in CFS patients.

Recently, there are cases where anterior esthetic prostheses are fabricated for better esthetics, but biologic, mechanical factors could be overlooked, too focusing on esthetic factor. This leads to changes in neutral zone, dentition, position of tongue and lips, occlusion and anterior guidance causing inaccurate pronunciation. Therefore, consideration of systematic diagnosis and treatment procedure are required. In this case, prosthesis was refabricated through a systematic diagnosis and treatment procedure using four factor (acoustic analysis, esthetic analysis, occlusion, neutral zone) for the patient who complained of inaccurate pronunciation and esthetics of the fixed prosthesis fabricated 10 years ago. Thus, by promoting functional, esthetic recovery, this case report demonstrates satisfying results to both the patient and dentist.

Personal image concerns a person's talent, expertise, as well as the internal and external image. It is a core value that differentiates one individual from another. As personal branding via personal image management has become more important, there is a fast-growing number of online systems that provide self-test programs to analyze one's style and habits and also provide expert advice for not only styles but lifestyles as well. This study develops a systematic and objective personal image consulting system and offers basic information for the research of personal image making. For that purpose, the study attempts to examine the present state of global companies that use online image consulting programs and analyze their digital content. The results are as follows: 1) two domestic companies, Colorz and Atzine, and seven foreign companies, notably Covet and Boutique, were brisk in business; 2) two types of personal image-diagnosis programs - Visual search and Virtual matching - are now in operation; and 3) mobile applications exist as an evolved personal image-diagnosis program. With an increased interest in such programs, various companies at home and abroad are establishing systematic and scientific analysis systems, which are needed for personal image-making online. Under these circumstances, domestic companies are also urged to enhance levels of image-diagnosis content and actual commercialization and utilization, to develop programs that enable objectified, systematic personal image-making. To this end, the results of this study may serve as a helpful tool to consider future directions.

FCM(Fuzzy Cognitive Map) is proposed for representing causal reasoning. Its structure allows systematic causal reasoning through a forward inference. By using the FCM, authors have proposed FCM-based fault diagnostic algorithm. However, it can offer multiple interpretations for a single fault. In process engineering, as experience accumulated, some form of quantitative process knowledge is available. If this information can be integrated into the FCM-based fault diagnosis, the diagnostic resolution can be further improved. The purpose of this paper is to propose an enhanced FCM-based fault diagnostic scheme. Firstly, the membership function of fuzzy set theory is used to integrate quantitative knowledge into the FCM-based diagnostic scheme. Secondly, modified TAM recall procedure is proposed. Considering that the integration of quantitative knowledge into FCM-based diagnosis requires a great deal of engineering efforts, thirdly, an automated procedure for fusing the quantitative knowledge into FCM-based diagnosis is proposed by utilizing self-learning feature of neural network. Finally, the proposed diagnostic scheme has been tested by simulation on the two-tank system.

A systematic way of failure diagnosis in a linear system with decentralized estimators is developed. The generalized likelihood ratio (G.L.R) approach to failure detection and identification is used for designing a diagnosis system in each subsystem based on the innovation analysis. For the simplicity of the theoretical formulation, a design scheme of failure diagnosis is developed for the system decomposed into two subsystems. To demonstrate the effectiveness of our approach, several simulation studies have been carried out on a third-order linear system which is constructed of a second-order damped oscillator and a first-order lag.

We proposed in this paper a systematic way for analyzing discrete event dynamic systems to classify faults and failures quantitatively and to find tolerable fault event sequences embedded in the system. An automated failure diagnosis scheme with respect to the nominal normal operating event sequences and the supervisory control problem for tolerable fault event sequences is presented. Moreover the supervisor failure diagnosis problem with respect to the tolerable fault event sequences is considered. Finally, a plasma etching system example is presented.

We are developing a shared remote control mobile robot for aerial work in nuclear power plants (NPPs); a robot consists of a mobile platform, a telescopic mast, and a dual-arm slave with a working tool. It is used at a high location operating the manual operation mechanism of a fuel changer of a heavy water NPP. The robot system can cut/weld a pipe remotely in the case of an emergency or during the dismantling of the NPP. Owing to the challenging control mission considering limited human operator cognitive capability, some remote tasks require a shared control scheme, which demands systematic software design and integration. Therefore, we designed the architecture of the software systematically.
