This study investigated the agents for self-healing system that could be developed to prevent UST(underground storage tank) from leaking. The system involves short range wireless communication to locate a leakage. Four commercially available silicons are arbitrarily chosen to evaluate suitability as a self-healing agent through a series of laboratory experiments. finally the experiments are simulated using computational Fluid Dynamic Program.

Background: First-line drugs, if sensitive, are the most potent drugs in the treatment of multidrug-resistant tuberculosis (MDR-TB). This study examined the frequency and risk factors associated with acquired drug resistance to first-line drugs during a standardized treatment using first-line drugs in patients with MDR-TB. Methods: This study included patients who were diagnosed with MDR-TB at the National Masan Tuberculosis Hospital between January 2004 and May 2008, treated with standardized first-line drugs, and for whom the preand post-treatment results of the drug susceptibility test were available. Their medical records were reviewed retrospectively. Results: Of 41 MDR-TB patients, 14 (34.1%) acquired additional resistance to ethambutol (EMB) or pyrazinamide (PZA). Of 11 patients initially resistant to isoniazid (INH) and rifampicin (RFP), 3 (27.3%) acquired additional resistance to both EMB and PZA, and 3 (27.3%) to PZA. Of 18 patients initially resistant to INH, RFP and EMB, 6 (33.3%) acquired additional resistance to PZA. Of 6 patients initially resistant to INH, RFP and PZA, 2 (33.3%) acquired additional resistance to EMB. Ten of the 41 MDR-TB patients (24.4%) changed from resistant to susceptible. No statistically significant risk factors associated with acquired resistance could be found. Conclusion: First-line drugs should be used cautiously in the treatment of MDR-TB in Korea considering the potential acquisition of drug resistance.

reverse transcription은 AIDS를 일으킨다고 알려진 바이러스인 HIV-1의 번식에는 필수적이나 인체 세포에는 필수적이 아니기에 이 단계를 표적으로 하는 AIDS 치료제가 우선적으로 개발되었다. 그 단계에 필요한 효소가 바이러스에 의해 만들어진 RT이며 이 효소의 작용을 저해하는 nucleoside 유도체들인 AZT, DDC, DDI 들이 현재 AIDS 환자의 치료에 사용되고 있다. 이들 nucleoside 유도체들은 세포안으로 들어가 triphosphate 형태로 변화된 후 dNTP와 상경적으로 경쟁하며 합성 중인 바이러스의 DNA에 들어가 DNA의 합성을 정지시켜 바이러스의 증식을 억제한다. 그러나, 이들 nucleoside 유도체들은 치료용량에서 심한 독성을 나타낼 뿐만 아니라 장기 투여시 내성을 나타내는 바이러스가 생겨나 AIDS의 치료를 불가능하게 하고 있다.

The progression of aging and the increase in musculoskeletal diseases have led to an increase in invasive treatment methods, including various surgical methods, but conservative treatment should be attempted before surgical treatment in musculoskeletal diseases. Medication for pain control, such as acetaminophen, non-steroidal anti-inflammatory drugs, steroid, opioids, antidepressants, etc., is one of the most popular methods for pain control. If the pain receptors on peripheral organ are stimulated, pain is transmitted to the brain by the ascending pathway, and the brain then secretes endogenous opioids, such as endorphin, by the descending pathway for pain control. Opioids are substances that act on the opioid receptors, and there are three receptors for opioids. The affinity for each receptor varies according to the tissue and the patient's systemic status. Antidepressants work on the synapses in the central nervous system and its main mechanism is regulation of the ascending pathway. This is mainly effective in chronic pain and neuropathic pain, which is similar in effectiveness to opioids. This review focuses on the effectiveness, method of use, and side effects of opioids and antidepressants.

당뇨병 치료 방법은 식사조절, 운동, 교육, 약물치료, 인슐린 주사 등이다. 운동은 당뇨 치료의 기본이다. 성인 당뇨병환자의 대부분인 제 2형 당뇨병에서 운동은 혈당을 낮추며, 체중을 감소시키고, 체내 지방질을 좋아지게 하며, 심장.혈관.신경계 및 망막 합병증을 감소시킨다. 인슐린 주사를 반드시 맞아야 하는 제 1형 당뇨병환자가 운동을 하면 인슐린 주사를 줄이거나 맞지 않을 수 있다.

배경: 약물로 인한 Clostridium difficile-associated diarrhea (CDAD)는 널리 알려져 있으며 우리나라에서 항생제와 프로톤 펌프 억제제 소모량을 고려할 때 질환 치료과정에서의 CDAD 발생빈도 및 CDAD 유발 이전에 투여한 약물의 사용빈도와 CDAD의 치료방법을 조사할 필요성이 있다. 방법: 경상대학교 병원에서 2011년 1월부터 6월까지의 입원환자를 대상으로 대변 독소 검사에 의해 CDAD로 판명된 환자의 성별, 연령분포, 질환명, 입원병동, 재발률을 조사하였으며 CDAD 판명이전에 투여한 약제 및 CDAD 판명후 치료약제를 조사하였다. 결과: 연구기간 동안 CDAD 대변 독소 검사 의뢰된 환자수는 1,500명이었으며 CDAD 양성은 111명(9.3%)이었고, 재발은 29명(26.1%)이었다. CDAD를 주소로 입원한 환자는 17명 (15.3%)이었고, 나머지는 입원기간 중에 발생하였다. CDAD 양성인 환자의 연령대는 60대에서 32.4% (36/111명) 이었고, 내과병동에서 34.2%를 나타내었고, 재발률은 외과계 병동에서 41.4%로 가장 높게 나타났다. CDAD 환자의 17% (19/111명)은 항암제 투여 동안 발생하였으며 CDAD 발생 전 사용약물로는 세팔로스포린계 항생제가 162회로 가장 빈번하게 사용 되었으며, 히스타민2 수용체길항제 107회, 스테로이드 82회, 비 스테로이드 항염제 79회, 프로톤 펌프 억제제 77회, 하제 59회, 항암제가 33회 처방되었다. CDAD 치료약제로는 8종의 약제가 241회 처방 되었으며 metronidazole이 99회로 가장 빈번하게 사용되었고, vancomycin이 37회로 나타났다. 결론: 입원환자에 있어서 CDAD양성은 특히 고령의 암환자가 많아 항암제 투여 시에는 CDAD 발생에 주의해야 할것으로 보인다. CDAD의 치료약제로는 metronidazole이 vancomycin 보다 많이 사용되는 것으로 나타났다.

Toxic epidermal necrolysis (TEN) is a rare, acute and life-threatening cutaneous drug reaction. TEN is characterized by the sudden onset of extensive necrosis in the epidermis and frequent mucous membrane involvement. The pathogenesis has not yet been elucidated. In addition, no particular treatment for TEN has been established. We report a case of TEN in a 14-year-old-boy, which might have been caused by steroids with enalapril treatment for membranous nephropathy. He recovered after intravenous immunoglobulin therapy.

Recently a drama that features a lawyer with autism spectrum disorder has attracted a lot of attention, raising interest in the difficulties faced by people with autism spectrum disorders. If the Autism spectrum gets detected early and proper education and treatment, the prognosis can be improved, so the development of the treatment is urgently needed. Drugs currently used to treat autism spectrum often have side effects, so Digital Therapeutics that have no side effects and can be supplied in large quantities are drawing attention. In this paper, we introduce 'AEmotion', an application and a Digital Therapeutic that provides emotion and facial expression learning for toddlers with an autism spectrum disorder. This system is developed as an application for smartphones to increase interest in training autistic children and to test easily. Using machine learning, this system consists of three main stages: an 'emotion learning' step to learn emotions with facial expression cards, an 'emotion identification' step to check if the user understood emotions and facial expressions properly, and an 'expression training' step to make appropriate facial expressions. Through this system, it is expected that it will help autistic toddlers who have difficulties with social interactions by having problems recognizing facial expressions and emotions.

Eruptive disturbance of the permanent lower first molar is an uncommon condition caused by physical barriers on the eruption path or failure of the eruptive mechanism. Once eruptive disturbance of the permanent lower first molar is diagnosed. treatment should be started as soon as possible to establish a normal eruption pathway and to avoid any detrimental effects on the developing occlusion A case of primary retention of the mandibular first permanent molar treated with operculectomy and forced eruption which showed good treatment results and stability is described
