Percutaneous epidural neuroplasty (PEN) is a known interventional technique for the management of spinal pain. As with any procedures, PEN is associated with complications ranging from mild to more serious ones. We present a case of intracranial subdural hematoma after PEN requiring surgical evacuation. We review the relevant literature and discuss possible complications of PEN and patholophysiology of intracranial subdural hematoma after PEN.

Thoracoscopic esophagectomy for esophageal cancer can be performed in multiple positions, such as the lateral decubitus position or prone position, using various techniques. Each approach has its own advantages and disadvantages, and surgeons can select an appropriate approach based on their preferences. Except for the reduction of pulmonary complications, the benefits of thoracoscopic esophagectomy, including oncologic outcomes, have not been proven scientifically. This review describes the approaches and procedures of thoracoscopic esophagectomy and presents scientific evidence for this procedure.

Recent advances in bronchoscopy have led to changes in clinical diagnostics and therapeutics in pulmonary medicine. In diagnostic bronchoscopy, there have also been new developments in endobronchial ultrasound technology which may be incorporated into clinical practice in the near future. Functional bronchoscopy, which evaluates information such as airway pressure, airflow, or gas exchange, suggests promising clinical advances in the near future. In therapeutic bronchoscopy, bronchoscopic volume reduction is a novel approach for the treatment of severe emphysema. In this review, seven recently published articles representing current advances in bronchoscopy are summarized and discussed.

Purpose: The aim of this article is to review a group of lesions associated with periodontal ligament (PDL) widening. Materials and Methods: An electronic search was performed using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as "periodontium", "periodontal ligament", "periodontal ligament space", "widened periodontal ligament", and "periodontal ligament widening". Results: Out of nearly 200 articles, about 60 were broadly relevant to the topic. Ultimately, 47 articles closely related to the topic of interest were reviewed. When the relevant data were compiled, the following 10 entities were identified: occlusal/orthodontic trauma, periodontal disease/periodontitis, pulpo-periapical lesions, osteosarcoma, chondrosarcoma, non-Hodgkin lymphoma, progressive systemic sclerosis, radiation-induced bone defect, bisphosphonate-related osteonecrosis, and osteomyelitis. Conclusion: Although PDL widening may be encountered by many dentists during their routine daily procedures, the clinician should consider some serious related conditions as well.

Time series are used in many studies for model building and analysis. We must be very careful to understand the kind of time series data used in the analysis. In this review article, we will begin with some issues related to the use of aggregate and systematic sampling time series. Since several time series are often used in a study of the relationship of variables, we will also consider vector time series modeling and analysis. Although the basic procedures of model building between univariate time series and vector time series are the same, there are some important phenomena which are unique to vector time series. Therefore, we will also discuss some issues related to vector time models. Understanding these issues is important when we use time series data in modeling and analysis, regardless of whether it is a univariate or multivariate time series.

Although the prevalence of rotator cuff tears is dependent on the size, 11% to 94% of patients experience retear or healing failure after rotator cuff repair. Treatment of patients with failed rotator cuff repair ranges widely, from conservative treatment to arthroplasty. This review article attempts to summarize the most recent and relevant surgical options for failed rotator cuff repair patients, and the outcomes of each treatment, except arthroplasty.

The traveling purchaser problem(TPP) is a generalization of the well-known traveling salesman problem(TSP), which has many real-world applications such as purchasing the required raw materials for the manufacturing factories and the scheduling of a set of jobs over some machines, and many others. TPP also could be extended to the vehicle routing problem(VRP) by incorporating additional constraints such as multi-purchaser, capacity, distance and time restrictions. In the last decade, TPP has received some attention of the researchers in the operational research area. However it has not received the equivalent interest as much as TSP and VRP. Therefore, there does not exist a review of the TPP. The purpose of this paper is to review the TPP and to describe solution procedures proposed for this problem. We also introduce the ILP formulation for the multiple TPP(mTPP) which is generalized type of TPP. We compare the system performance according to change from TPP to mTPP.

The purpose of this study were to enhance the gender equality in rural area through develop Gender Equality Consciousness Improvement Education Program for rural couples. For these purposes, procedures conducted and results were as follows; 1) This study was conducted through the literature review and research data for gender equality of people in rural area. Based on the review and research data, It was developed gender equality consciousness improvement education program and evaluated sex-role complex through structured questionnaires. 2) This program was consisted of 4 sessions, namely, understanding on the concept and necessarity of gender equality, understanding on the man and woman, gender equality consciousness evaluation, and establishing on the equal man and woman role in rural community. Using program materials for educators, this program will be used effectively by professional worker in rural community.

Vancomycin-resistant enterococci[VRE] are rare cause of meningitis, occurring in immunocompromised patients, severely ill, hospitalized patient, and patients who have undergone neurosurgical procedures. Resistance to vancomycin has increased in frequency during the past few years. Limited therapeutic options are available for VRE infectionsandtheoptimumtherapy has not been established. We report a case of VRE meningitis that was successfully treated with administration of quinupristin-dalfopristin [Synercid] by both intravenous and intraventricular routes. A brief review of the literature is provided, which indicates that optimal management with Synercid should include daily intraventricular doses of at least 2mg and intravenous 0.5mg/kg every 8 hours. We also review the previously reported cases of VRE meningitis.

The aim of this paper is to review KORUS FTA Rules of Origin. Although there are some differences in terms of structure and contents, KORUS FTA Rules of Origin is not much different from the other FTA's texts that Korea has already concluded. Textile and Apparel chapter is also separately specified. For textile and apparel goods, Korea and the US agreed to adopt 'yam-forward rule', allowing exceptions for certain goods. Both sides also agreed to introduce procedures for permitting to use non-Party's materials when fibers ryarns rfabrics are not available in commercial quantities. Overall evaluation on KORUS FTA is considered to be positive. Economically, KORUS FTA is expected to provide good opportunities for Korean companies to access the US market. Politically, Korea and the US can take advantage of KORUS FTA to reinforce the relationship between the two countries.
