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.

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.

비디오 기반 화염 감지 기법은 입력 비디오 영상에서 화염과 비슷한 색상을 가지고 움직임이 있는 영역에 대해서 화소 단위로 화염의 특성을 가지고 있는지를 시간적, 공간적 특징 분석을 통하여 확인한다. 비디오 기반 화염 감지 기법 연구의 가장 중요한 부분 중 하나는 화염 감지 성능이 저하되지 않고 어떻게 거짓 경보의 빈도를 줄일 수 있는가 하는 것이다. 기존의 방법들은 전기 장치로 만들어진 불빛들 중에서 자동차 전조등과 같은 일반적인 움직임을 가진 전기 불빛에 의한 거짓 경보는 쉽게 제거하고 있다. 그러나 경광등, 경고등 그리고 네온사인과 같이 깜빡거림이 있는 전기 불빛은 색상과 시간적, 공간적인 특징이 실제 화염과 비슷할 경우 거짓 경보를 발생시키는 요인이 되고 있다. 본 논문에서는 경광등, 경고등 그리고 네온사인과 같이 깜빡거림이 있는 전기 불빛 화소들의 주기 신호 검출을 통하여 진짜 화염이 아님을 확인하는 거짓 경보 제거 기능을 갖춘 비디오 화염 감지 기법을 제안한다. 실험 결과 화재 감지 성능은 기존의 방법과 비슷하였으나 기존의 방법이 거짓 경보를 발생시키는 시험 비디오에서 거짓 경보가 발생되지 않음을 볼 수 있었다.

국내 사면안정성 설계기준은 우기 건기시로 제안되어 사용되고 있지만, 한계평형해석의 결과로 산출되는 안전율이 외부조건에 의해 변화되며, 특정한 변곡점이 없기 때문에 사전에 안전을 확보하기 어렵다는 점에 착안하여 경보발령, 서행 및 열차정지 등과 같은 안전규정의 설정이 가능한 대안을 검토하였다. 이를 위하여 본 연구에서는 불포화토질역학과 신뢰성해석에 기초하여 현행 안전율을 보조할 수 있는 부가적인 지표를 도입하였다. 강우침투에 따라 안전율과 신뢰지수는 지수함수형태로 감소하는 특징을 보이며, 파괴확률은 누적확률분포함수 형태로 증가함을 확인할 수 있었다. 본 연구에서 검토한 부가지표인 파괴확률 변화속도는 현재의 기준 안전율 부근에서 명백한 변곡점을 갖는 특징이 있다. 이를 이용하면 사면의 안전관리와 모니터링 시스템에 대한 적정 규정으로 적용이 가능할 것으로 판단된다.
