Idiopathic hypertrophic pachymeningitis (IHP) is a rare disease involving localized inflammatory thickening of the intracranial or spinal dura mater without an identified cause. Seizure is a very unusual presentation of IHP. We present a 58-year-old-female patient with seizures caused by IHP. This case indicates that although IHP is rare, it has the potential to cause seizures.

소아의 폐쇄성 수면 무호흡증은 흔히 편도 아데노이드 비대증으로 인해 발생하는 것으로 알려져 있으나 비만, 두개 악안면 기형 등 다양한 원인에 의해서도 발생할 수 있다. 소아의 폐쇄성 수면 무호흡증은 야뇨증, 사건 수면, 행동 장애 등과 같은 다양한 합병증을 동반할 수 있다. 그 원인이 편도 아데노이드 비대증이면 수술적인 제거를 통해 증상 호전을 기대할 수 있으나 비만 등 다른 원인에 의한 것이라면 지속성 상기도양압술과 체중 감량 및 생활습관 변화를 통한 치료가 필요하다. 저자들은 편도 아데노이드 절제술 시행 후에도 심한 폐쇄성 수면 무호흡증이 지속되고 다양한 합병증이 나타난 환아에서 상기도양압술로 무호흡 관련 증상 및 동반된 합병증의 호전을 보인 1례를 경험하였기에 보고한다.

Acute osteomyelitis caused by Klebsiella pneumoniae is rare in the oral and maxillofacial region. Klebsiella pneumoniae is a Gram-negative bacillus and the normal flora of the human body, but it can cause pneumonia, urinary tract infection, meningitis, and osteomyelitis in patient with compromised immune systems. These infections are mainly caused by nosocomial infection. Microbacterial osteomyelitis was developed by clinical cause such as tooth extraction, fracture, and surgical history, which requires long-term antibiotic administration and surgical treatment. This report describes that a 56-year-old male patient with acute osteomyelitis caused by Klebsiella pneumoniae infection after implant placement was treated with intravenous administration of ertapenem without open surgery treatment. Through this case, we report that antibiotic susceptibility test is essential for the treatment of acute osteomyelitis caused by a bacterial infection resistant to empirical antibiotics, and early administration of appropriate antibiotics can reduce the possibility of extensive bone destruction or additional open surgery.

본 논문은 부산 실내사격장 화재와 관련하여 불과 수 초 이내에 급격하게 연소 확대된 원인에 대하여 연구하였다. 급속한 연소 확대 원인 분석을 위하여 실내사격장에 광범위하게 사용되는 스펀지형 흡음재의 연소실험을 수행하였다. 흡음재 연소 실험결과, 일반형의 경우, 착화와 동시에 급속히 연소되는 특징을 나타내었다. 난연 처리된 흡음재는 착화와 동시에 자체 소화되는 특성을 나타내었으나, 화약잔사를 난연 흡음재에 부착시키는 경우, 착화와 동시에 급격히 연소되는 결과를 나타내었다. 발화원인에 대한 분석을 위하여 총기사용 과정에서 발생되는 유탄의 비산거리 및 크기를 실측하였으며, 화약잔사에 대한 충격 강도 실험 결과를 바탕으로 최소 착화 에너지를 계산하였다. 유탄의 충격 후, 탄속 감소 및 유탄의 크기에 따른 운동에너지 계산을 통하여 유탄이 화약잔사에 충격하는 경우, 충분한 발화 가능성이 있음을 확인하였다.

Congenital aortic stenosis, a relatively uncommon congenital heart disease, may cause heart failure and may be fatal. In recent years, increased clinical awareness and improved diagnostic and operative technique has made accurate diagnosis and successful treatment possible. Recently we experienced 2 cases of congenital aortic stenosis, and which was corrected surgically. The first case was 9 years old boy, and second case was 16 years male. Preoperative diagnosis was entertained by angiography and cardiac catheterization in both cases. In each case, aortic valve opening was widened by incision along the fused commissure between the combined left and right coronary cusp on one side, and the noncoronary cusp on the other side. Post-op. pressure gradient between the aorta and left ventricle markedly reduced, in the first case, 50mmHg, and in the 2nd case, 55mmHg.Both patients discharged with good results 2 weeks after open heart surgery.

Objective : The purpose of this study was to report the improvements of patients with globus pharyngeus treated with herbal medication from Shanghanlun. Methods : Each patient was diagnosed with Greater-yang disease 29th provision of Shanghanlun, and Gamchogungang-tang was used to treat. The result was evaluated by Glasgow-Edinburgh Throat Scale(GETS). Results : The GETS score decreased from 23 to 4 after 40 days of administration in case 1 and from 31 to 1 after 15 days of administration in case 2. Conclusions : Globus pharyngeus improved in each case. This case report suggests that '急' based on the 29th provision of Shanghanlun, can be a direct psychological cause of globus pharyngeus.

A flare from an Air Force fighter was abnormally dispensed during the landing. To determine the cause of the abnormal dispensing, fracture analysis, signal analysis and reproduction experiments based on physics of failures were performed. The primary cause of the failure was analyzed to be due to an intermittent fault of an internal circuit card in the AN/ALE-40 chaff/flare dispenser by a broken lid of a capacitor, and the root cause which had derived the primary cause was considered to be an improper handling during the domestic maintenance which were changed from the overseas maintenance due to the DMSMS problem. Therefore, the overall process of the maintenance capability development system was reviewed and alternative ways that considers maintenance error decision aid(MEDA) for system improvement were suggested to prevent further failures.

The conventional computerized numerical controller (CNC) of machine tools has been increasingly replaced by a PC-based open architecture CNC (OAC) which is independent of the CNC vendor. The OAC and machine tools with OAC led the convenient environment where it is possible to implement user-defined application programs efficiently within CNC. Tis paper proposes a method of operational fault cause diagnosis which is based on the status of programmable logic controller (PLC) in machine tools with OAC. The operational fault is defined as a disability state occurring during normal operation of machine tools. The faults are occupied by over 70% of all faults and are also unpredictable as most of them occur without any warning. Two diagnosis models, the switching function (SF) and the step switching function (SSF), are propose in order to diagnose the fault cause quickly and exactly. The cause of an occurring fault is logically diagnosed through a fault diagnosis system (FDS) using the diagnosis models. A suitable interface environment between CNC and develope application modules is constructed in order to implement the diagnostic functions in the CNC domain. The diagnosed results were displayed on a CNC monitor for machine operators and provided to a remote site through a web browser. The result of his research could be a model of the fault cause diagnosis and the remote monitoring for machine tools with OAC.

Purpose: In this study, the goal is to analyze this case to prevent the same accidents when using one-shot rifle. Methods: Detailed analysis of damaged parts must first be made in order to determine the cause of the abnormal explosion. The cause of abnormal operation can be determined by analyzing the information of damaged components and the firing mechanism of the weapon step by step. Also we can refer to a statement of shooter, witness and accident scene situation. Based on this theory, cause of abnormal firing can be narrow down. Results: Fracture of pin for fixing firing and latch is cause of abnormal operation of firing. Conclusion: It is deemed that periodic inspection and fundamental improvement of the structure are required to prevent the same accident as this.

CISG articles 34 and 37 clearly allow the seller to cure any nonconformity in documents of sale or performance prior to the date for delivery if it does not cause the buyer unreasonable inconvenience or unreasonable expense. CISG article 48 allows a seller to cure the performance even after the date for delivery if it does not cause the buyer unreasonable delay, unreasonable inconvenience or unreasonable uncertainty of reimbursement by the seller of expenses advanced by the buyer. The wording any failure to perform is broad enough to include a delay. The seller's right to cure relates to all his obligations. The seller may remedy 'any failure to perform his obligations'. This language is broad enough to include a defect in documents. In some cases the fact that the seller is able and willing to remedy the non-conformity of the goods without inconvenience to the buyer, may mean that there would be no fundamental breach unless the seller failed to remedy the non-conformity within an appropriate time. It cannot generally be said what unreasonable inconvenience means. This can only be decided on a case-by-case basis. The seller must bear the costs involved in remedying a failure to perform. The curing of a failure to perform may have influence on the amount of the damage claimed. Insofar as the seller has the right to cure, the buyer is in that case obliged to accept the cure. If he refuses to do so, he can neither avoid the contract nor declare a reduction in price. This rule clearly shows the underlying concept of the CISG, to keep to the contract, if possible. Should the buyer requires delivery of substitute goods and the seller offers repair, it depends on the expense each case. The buyer must receive the request or notice by the seller. The relationship between the seller's right to cure and the buyer's right to avoid the contract is unclear. The buyer's right to avoid the contract should not nullify the seller's right to cure if the offer is reasonable. In addition, whether a breach is fundamental should be decided in the right of the seller's offer to cure.
