  • An intracapsular and pericapsular infection of the temporomandibular joint (TMJ) is rare. The invasion of bacteria into the joint space can occur through several routes. Among them, hematogenous spread is most common. This report describes three cases of abscess formation in the TMJ (intracapsular and pericapsular infection). The patients were treated with supportive care and surgical intervention (incision and drainage) under hospitalization, and their symptoms had improved. Pain of the TMJ is a typical symptom of temporomandibular joint disorders (TMD). On the other hand, an infection of the TMJ can also cause pain on the affected side, and can be misdiagnosed as routine TMD. Therefore, the possibility of an infection of the TMJ cavity should be considered when treating TMD.

  • The importance of bronchial occlusion which occurs in the natural course of tuberculosis as an inconstant but very fortunate event became obscured with the popularity of resection therapy for pulmonary tuberculosis and the resectional surgery and thoracoplasty are the standard method of surgical procedure in the treatment of pulmonary tuberculosis. However in some cases of far advanced pulmonary tuberculosis, the need for another surgical methods arise when standard method is not indicated under the consideration of poor pulmonary function or operative and postoperative complications such as bronchial fistula. The ligation and division of bronchus draining the involved part of the lung is one of the applicable method among the another surgical procedures. The authors experienced one case of far advanced pulmonary tuberculosis who had a huge cavity in the right upper lobe and a small cavity in the superior segment accomanying with several nodular densities in the basal segment and contralateral left lung field, and treated with right upper lobectomy, ligation and division of the superior segmental bronchus and concomitant rib-resectional thoracoplasty in order to prevent postoperative bronchial fistula and to preserve maximal lung function. The postoperative course was smooth without complication regarding to bronchial ligation and division technique and the general condition has been excellent without symptoms. The postoperative sputum examination for AFB on smear and culture has been negative during the 11 month period of follow up, and X-ray of the chest including tomography demonstrated no evidence of residual cavity indicating succesful collapse of cavity.

  • The pressing need to mitigate greenhouse gas emissions has stimulated a renewed interest in nuclear energy worldwide. However, while numerous countries have shown interest in nuclear power over the course of history, many of them have not continued their pursuit and chosen to defer or abandon their peaceful nuclear power projects. Scrapping a national nuclear power program after making initial efforts implies significant challenges in such a course or a waste of national resources. Therefore, this study aims to identify the crucial factors that influence a country's decision to terminate or hold off its peaceful nuclear power programs. Our empirical analyses demonstrate that major nuclear accidents and leadership changes are significant factors that lead countries to terminate or defer their nuclear power programs. Additionally, we highlight that domestic politics (democracy), lack of military alliance with major nuclear suppliers, low electricity demand, and national energy security environments (energy import, crude oil price) can hamper a country's possibility of regaining interest in a nuclear power program after it has been scrapped, suspended, or deferred. The findings of this study have significant implications for policymakers and stakeholders in the energy sector as they strive to balance the competing demands of energy security, and environmental sustainability.

  • Purpose: Although glyphosate-surfactant herbicide intoxication is relatively mild toxic in humans, we encountered an atypical clinical presentation. We performed this study to understand the atypical clinical course and factors associated with severe intoxication after glyphosate ingestion. Methods: We conducted a retrospective study of 61 patients (male 43, mean age $54{\pm}18.8$ years) who were presented with glyphosate ingestion between March 1997 and March 2011. The severe intoxication group was defined as patients with systolic blood pressure less than 90 mmHg, respiratory distress needing intubation, or altered mental state. Results: Of the 61 patients, 22 patients (36.1%) had a severe clinical course, 1 patient (1.6%) had died and 1 patient (1.6%) had moribund discharge. The most common symptoms were nausea with or without vomiting which occurred in 30 patients (49.2%). Twenty-seven patients had metabolic acidosis that was the second most common medical complication. Advanced age, pH, base excess, $HCO_3$, Sat, creatinine, X-ray abnormalities and ECG abnormalities were significant factors. Hemoglobin, platelet, $pO_2$, $pCO_2$, BUN, sodium, potassium and AST levels were not different comparing the laboratory characteristics between the severe and mild intoxication groups. Conclusion: The results of this study showed that severe intoxication occurred in 22 patients (36.1%) after glyphosate intoxication. Advanced age, pH, base excess, $HCO_3$, Sat, creatinine, X-ray abnormality and ECG abnormalities were significant predictive factors for severe intoxication in patients with glyphosate surfactant herbicide poisoning.

  • ABEEK recommends convergent engineering projects to nurture creative problem-solving ability for 1st year engineering students through 'Creative Engineering Design' course. However, 1st year engineering students, who have not yet studied core subjects in engineering, have difficulties understanding and coping with the challenges posed by the engineering-related projects. For this reason, the educational objectives of this course are usually frustrating to achieve by the instructor. In this paper, by using the problem-solving process and skills of critico(-creative) thinking, we prepare guidelines for creative engineering design education that allow 1st-year students to effectively participate in engineering projects without a complete understanding of the design process which is to be studied. Also, we present a case study that applies the guidelines to an on-going creative engineering design course and discusses the outcomes by showing student-generated works. The results showed that the intuitive content and everyday expression of critico(-creative) thinking education enabled the instructor to effectively guide their students through the requirements of engineering projects without relying on advanced engineering design methods, and that the application of these guidelines also helped improve students' communication skills, including presentation. We show that the guidelines for creative engineering design education utilizing the problem-solving process and skills of critico(-creative) thinking is not only contributing to achieving the educational objectives of the creative engineering design course but can also be an educational paradigm that incorporates critico(-creative) thinking education into engineering education.

  • In this paper, a new positioning method with incoherence of white light is described and practically implemented to attach VCR heads on a drum very accurately. This method utilizes the Michelson Interferometer which uses white light with short coherence length as the light source to generate interference fringes only in case the optical path difference is shorter than about 2.mu.m. The course position of VCR heads and the fine are determined by appearance and visibility of interference fringes, respectively. The appearance are detected by an image processing technique using FFT(Fast Fourier Transform).
