  • Background: There have been no large-scale population-based studies to estimate the subsequent risk of primary liver cancer (PLC) among patients with pyogenic liver abscess (PLA). This study aimed to provide relevant data. Materials and Methods: The Taiwan Longitudinal Health Insurance Database for the years 2000 and 2005 was used. The PLA group were adult inpatients who were newly diagnosed with PLA from 2000 to 2008. The control group was randomly selected and matched with the PLA group in terms of age, sex, and date in which medical treatment was sought other than for PLA. Results: There were 1,987 patients each in the PLA and control groups. In total, 56 had PLC, 48 (2.4%, 601.5 per 100,000 person-years) from the PLA group, and 8 from the control group. After adjusting for potential covariates, the hazard ratio of PLC for the PLA group was 3.4 times that of the control group (95% confidence interval = 1.6-7.3, p <0.001). The PLC risk for the PLA group was significantly higher within the first year after PLA diagnosis (hazard ratio: 35.4) as compared with the control group and became insignificant (hazard ratio: 2.0, 95% confidence interval = 0.8-4.9) more than one year after PLA diagnosis. Conclusions: Patients with PLA have a higher rate of PLC than matched controls, especially within the first year after the diagnosis of PLA, suggesting PLA is a warning sign for PLC.

  • In modern society, the amount of alcohol ingestion is increasing at a dangerous level, especially among women. One of reason for increased alcohol consumption is stress caused by social pressures. Alcohol is a kind of depressant of centric nervous system, so it can induce relaxation of body and decrease the stress. The evidence on the effects of alcohol on the fetus is somewhat hazy, whereas that of smoking is quite clear. The literature on the ingestion of alcohol strongly suggests that drinking during pregnancy is associated with teratogenic effect and low birth weight. Therefore, the adverse effect of alcohol ingestion during pregnancy must be informed to public. More remarkable warning sign about alcohol ingestion must be attached on the top of bottles. This can be an effective measure for public education. Also legal sanction or tax imposition for the production of liquor be required. First of all, drinking habit or drinking culture must be changed. In fact, the strongest motivation of drinking in adolescent is a peer pressure which is related to drinking habit or culture. Secondly, early detection and treatment must be required to prevent from fetal alcohol syndrome. Accordingly, drinking history of pregnant women must be assessed as early as possible and health professional should give a warning about the abstinence of alcohol to drinking women. Thirdly, to minimize the adverse effects for mother, withdrawal syndrome by alcohol ingestion must be treated. to correct the malformation by fetal alcohol syndrome(FAS) can be corrected. Sometimes surgical intervention may be required for this purpose.

  • Objectives : Severe mental illness is a major risk factor for suicide. This study aimed to identify characteristics of patients who died by suicide among subjects who had been received service from a community mental health center. Methods : We searched individuals who had committed suicide in Gwangju Bukgu Community Mental Health Center since 2006. Sociodemographic and clinical data were gathered from medical records and their case managers and they were compared with those of general members in the center. Characteristics of schizophrenia patients who died by suicide were particularly summarized. Results : Twelve person committed suicide between 2006 and 2016. The characteristics of those who died by suicide were male (67%), diagnosis of schizophrenia (75%), aged below 50 (83%), unemployed (92%), past history of psychiatric hospitalization (100%), recent admission within 3 months (67%), past history of suicidal attempt (78%), family history of schizophrenia (58%), poor adherence to medication (58%), and use of daily rehabilitation program (42%). Ten out of twelve (83%) showed warning sign for suicide. All identified method of suicide in patients with schizophrenia was jumping from high building. Many patients with schizophrenia, who committed suicide, suffered from comorbid depressive symptoms (67%) and auditory hallucination (78%). Conclusion : Case managers should pay attention to and carefully manage individuals who showed suicidal warning, particularly with risk factors for suicide, such as unemployment, admission state or recent discharge from psychiatric hospital, poor adherence to medication, family history of schizophrenia, and a history of suicidal attempt.

  • Ictal tachycardia and bradycardia are common arrhythmias; however, ictal sinus pause and asystole are rare. Ictal arrhythmia is mostly reported in adults with temporal lobe epilepsy. Recently, ictal arrhythmia was recognized as a major warning sign of sudden unexpected death in epilepsy. We present an interesting case of a child with ictal sinus pause and asystole. A 27-month-old girl was hospitalized due to 5 episodes of convulsions during the past 2 days. Results of routine electroencephalography (EEG) were normal, but she experienced brief generalized tonic seizure for 3 days. During video-monitored EEG and echocardiography (ECG), she showed multiple myoclonic seizures simultaneously or independently, as well as frequent sinus pauses. After treatment with valproic acid, myoclonus and generalized tonic seizures were well controlled and only 2 sinus pauses were seen on 24-hour Holter ECG monitoring. Sinus dysfunction should be recognized on EEG, and it can sometimes be treated successfully with only antiepileptic medication.

  • In this experiment, we investigated 82 patients who suffered adverse reactions due to contrast medium. We selected the subjects out of 21,178 people who had an intravenous injection of contrast medium to undergo MDCT examination at one university hospital in Busan in 2007. As a result, the largest groups of the patients were as follows. 52.4% of the patients were male when classify by gender; 28.0% of the patients were 50's by age; 45% of the patients got when it was spring(April and March); 75.6% of the patients had a side effects when the speed of injection is 2.5mL/sec; 58.5% of the patients were suffered when the volume of injected contrast medium is over 130mL. Urticaria was the main symptom of side effect as 26.8%. And the main treatment for the effect was alleviating the symptoms before making patients to return home. Thus, practical preventive measures are needed as follows : use the OCS system to observe warning signs at risky patients, secure warming spaces for patients to cope with season changing, prepare enough emergency kits for the patients in danger, and establish CPR call systems, explain the risk of contrast medium and get agree about using contrast medium.

  • Emergencies and disasters can happen any time without any warning, and things can change and escalate very quickly, and often it is swift and decisive actions that make all the difference. It is a responsibility of the building facility management to ensure that a proven evacuation plan in place to cover various worst scenario to handled automatically inside the facility. To mapping out optimal safe escape routes is a straightforward undertaking, but does not necessarily guarantee residents the highest level of protection. The emergency evacuation navigation approach is a state-of-the-art that designed to evacuate human livings during an emergencies based on real-time decisions using live sensory data with pre-defined optimum path finding algorithm. The poor decision on causalities and guidance may apparently end the evacuation process and cannot then be remedied. This paper propose a cloud connected emergency evacuation system model to react dynamically to changes in the environment in emergency for safest emergency evacuation using IoT based emergency exit sign system. In the previous researches shows that the performance of optimal routing algorithms for evacuation purposes are more sensitive to the initial distribution of evacuees, the occupancy levels, and the type and level of emergency situations. The heuristic-based evacuees routing algorithms have a problem with the choice of certain parameters which causes evacuation process in real-time. Therefore, this paper proposes an evacuee routing algorithm that optimizes evacuation by making using high computational power of cloud servers. The proposed algorithm is evaluated via a cloud-based simulator with different "simulated casualties" are then re-routed using a Dijkstra's algorithm to obtain new safe emergency evacuation paths against guiding evacuees with a predetermined routing algorithm for them to emergency exits. The performance of proposed approach can be iterated as long as corrective action is still possible and give safe evacuation paths and dynamically configure the emergency exit signs to react for real-time instantaneous safe evacuation guidance.

  • The allergenic food labeling system for 12 foods has been operated in Korean school food service since 2012. This study was conducted to evaluate the food allergy status of Korean elementary school children's and their parents' perceptions of allergenic food labeling system. The parents of school aged(6-9yr olds) children in Gyeongbuk area were recruited to assist in this survey. Surveys were conducted by 404 parents. The prevalence of food allergy was 18.1%(73 students) and about one-half of the food allergic children had a family history of allergies, in particular, maternal family history. The major symptoms were related to skin and the major allergenic foods were mackerel, eggs, milk, wheat, crab and tomatoes. The parents eliminated the allergenic food from diet of 43.8% of the children with food allergy. Participants had an average knowledge score of 68% correct. The average knowledge score was higher for parents with food allergic children than for parents with intact children(p<.05). Over 61% of the respondents were not satisfied with allergenic food labeling system operated in school food service. The requirements for the allergenic food labeling system were the front-of-package labeling, conspicuous description and insert of warning sign. The parents estimated that the most important effect of the allergenic food labeling system was the improvement of psychological and physical health in children with food allergy. Because the only prevention method for food allergy is the restriction of allergenic food, the institutional device to expand the food labeling to unpackaged food as well as packaged food and to make people trust the food labeling should be prepared.

  • A video flame detection method analyze the temporal and spatial characteristics of the regions which have the flame-like color and moving objects in the input video. The video flame detector should be able to reduce a false alarm rate without the degradation of flame detection capability. The conventional methods can reject the false alarm caused by the car lights and some electric lights. However they make the false alarm caused by the warning lights, neon sign, and some periodic flickering lights which have the flame-like color and temporal features. This paper propose the video flame detection method with periodicity analysis based false alarm rejection. The proposed method can detect the periodicity of the flickering electric lights and can reject the false alarm caused by the periodic electric lights. The computer simulation showed that the proposed method did not make the false alarm in the test video with the periodic electric lights. But the conventional methods made a false alarm in the same test video.

  • Safety regulation of railway embankment is restricted by safety factor in dry season or rainy season in Korea. Safety factor which is results from the limit equilibrium analysis is varied by various external conditions. And because it has no reflection point, it is very difficult to manage the safety of trains. Safety regulation such like warning sign, reduce speed and train stop is the best choice to reduce the damage of embankments where it is worried about occurrence of disasters. In this study, additional index is proposed to support present safety standards based on unsaturated soil mechanics and reliability analysis. It is velocity of failure probability. It has an apparent reflection point near present safety regulation. It is possible to modify the regulation for safety management and monitoring system of embankments by using this index.
