According to the Security Services Industry Act security guards are not just workers but security-related service workers complementing the lack of police force and specializing in protecting of national important facilities, industrial facilities and apartment houses. Nevertheless, confusing or mixing the security service workers in "Security Services Industry Act" with the guards in the "Act on the Protection etc. of Temporary Agency Workers" lead to a constant debate about the scope of work of security guards. In the case of security service workers in "Security Services Industry Act" there is a strict limitations on security service worker's qualification such as strict reasons for disqualification, a need to pass training for new workers and qualification training, a need to report to the competent chief police officer if the security guard has placed or unplaced by the security service company. It distinguishes security service workers in "Security Services Industry Act" from the guards in the "Act on the Protection etc. of Temporary Agency Workers" and acknowledges the occupation of security service worker as a professional service worker. Therefore, security service workers in "Security Services Industry Act" shouldn't be obliged to do any other work than security work. If it is required to do other work than security work contract by the "Security Services Industry Act" doesn't apply but need to use a security guard according to "Act on the Protection etc. of Temporary Agency Workers" or hire a security guard on the employment contract. In this way, when security service workers in "Security Services Industry Act" are recognized as professional security related workers, the entire security industry can ultimately develop.

Reflex sympathetic dystrophy is a syndrome characterized by persistent, burning pain, hyperpathia, allodynia & hyperaesthesia in an extremity, with concurrent evidence of autonomic nervous system dysfunction. It generally develops after nerve injury, trauma, surgery, et al. The most successful therapies are directed towards blocking the sympathetic intervention to the affected extremity by regional sympathetic ganglion block or Bier block with sympathetic blocker; other traditional treatments include transcutaneous electrical stimulation, immobilization with cast & splint, physical therapy, psychotherapy, administration of sympathetic blocker, calcitonin, corticosteroid and analgesic agents. The purpose of this report is to evaluate and describe the effects of magnetic resonance following unsatisfactory results with traditional treatments of RSD. A 17 year old female patient, 1 year earlier, had received excision and drainage of pus at the right femoral triangle due to an injury caused by a stone. Afterwards, she experienced burning pain, knee joint stiffness, and muscle dystrophy of the right thigh, especially when standing and walking. Despite a year of number of traditional treatments such as: lumbar sympathetic block, continuous epidural analgesia, transcutaneous electrical stimulation, & administration of predisolone, her pain did not improve. Surprisingly, the patients was able to walk free from pain and difficulty after just one application of magnetic resonance. The patient has been successfully treated with further treatment of two to three times a week for approximately ten weeks. More recently, magnetic resonance has been demonstrated to produce effective results for the relief of pain in a variety of diseases. From our experiences we recognize magnetic resonance as a therapeutic modality which can provide excellent results for the treatment of RSD. It has been suggested that polysynaptic reflex which are disturbed in RSD may be modulated normally on the spinal cord level through the application of magnetic resonance.

Spinocerebellar Ataxia Type 3 (SCA 3) is a rare autosomal dominative disorder in which one of the neurodegenerative disorders is caused by a CAG repeat expansion on chromosome 14q32.1. The age at onset of disease is related to the size of the expanded CAG repeat. We present the prenatal diagnosis of SCA3 in a woman whose husband was known to carry an unstable CAG repeat expansion in the MJD gene. The diagnosis was made using PCR with a fluorescent probe for an expanded MJD allele. The normal ranges of (CAG)n of SCA3 are 14~38 repeats. The husband, who had a family history of SCA 3, has an expanded allele of 69 CAG repeats with a normal allele of 27 repeats. His wife had two normal alleles with 26 and 32 CAG repeats. The fetus had two normal alleles with 26 and 27 CAG repeats; consequently, the baby w as healthy. We report a case of prenatal diagnosis of SCA3 using a fluorescent PCR which is rapid and accurate.

Color rings have been commonly and widely used in many ecological and ornithological studies in the field, but color ring-induced injury in passerines is poorly documented. In this report, we describe the first case of toe loss caused by a dislocated split Darvic ring in a Pale Thrush (Turdus pallidus) that was recaptured 596 days after its initial capture and release on Hong-do Island, the Republic of Korea. We also found that a left hind toe of a Light-vented Bulbul (Pycnonotus sinensis) was entrapped by a split color ring when the bird was observed 135 days after the marking at Heuksan-do Island. Based on these two cases out of the 1,900 color ringed birds, we emphasize a precautionary approach following general guidelines in the application and use of color leg rings for future studies.

Altmetrics is an alternative impact evaluation index that evaluates the social interest in the research performance of individuals or institutions in universities, research institutions, and research fund support institutions. This study empirically analyzed what kind of attention a papers of domestic library and information science researchers published in an international academic journal was receiving in the international community using Altmetric explorer. As a result of the analysis, 230 papers were tracked. The average Altmetric Attention Score (AAS) was 6.63, but there were 2 papers that received overwhelming attention (over 170 points) as they were mentioned in news report and Twitter. Second, there was a tendency for high AAS to appear in cases where a domestic researcher participated as a co-author and the main author belonged to an overseas institution, and in the case where the research funds were supported by foreign government agencies. In addition to the field of the library information science or information system, the papers classified as the field of public health service and education showed high AAS, and it was confirmed that these papers were published in the journals of various fields such as life science. Finally, it was confirmed that there was a weak correlation of r =0.25 between the AAS and the number of citations of the analyzed paper, but a strong correlation of r =0.68 between the number of Mendeley readers and the number of citations.

A 1.6-year-old, intact male beagle dog was presented with three day history of odynophagia and anorexia. According to the history and radiographic findings, the patient was diagnosed with esophageal and gastric foreign body due to ingesting fishhooks. Gastroesophagoscopy revealed that one fishhook located in the thoracic esophagus cranial to the heart base and the other located in the cardia region were connected with a single fishing line. Gastrotomy was performed to remove the fishhook in the cardia region and to sever the connecting fishing line. After gastrotomy, endoscopic attempts to remove the esophageal fishhook with a three, five pronged endoscopic grasping forceps, and a biopsy were unsuccessful because the fishhook was embedded deeply in the mucosa membrane. A handmade cerclage wire(16G) shaped like a snare forceps was advanced into the esophagus while visualizing the fishhook endoscopically. The cerclage wire was used to hang and retract the foreign body. The fishhook was retracted orally, resulting in successful removal. Ten days after the operation, the patient fully recovered and was discharged.

A 74-year-old woman presented at our hospital with hemoptysis. Three months ago, she had endovascular stent-grafting done by a general surgeon for a saccular thoracic aneurysm that was found accidentally following an episode of fever and chills. Despite a lasting fever after the procedure, she was discharged without further treatment and follow-up. She was subsequently admitted to the hospital for evaluation and several exams were performed. Chest CT scans and an esophagoscopy identified an aorto-esophageal fistula at the level of the aorta that was covered by a previous stent-graft. After extensive administration of antibiotics, surgery was done - esophagectomy, cervical esophago-gastrostomy and replacement of the thoracic aorta. She was later discharged uneventfully.

Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin's B-cell lymphoma found primarily in the pediatric population. In the oral cavity, this tumor can grow rapidly and often brings about facial swelling or development of an exophytic mass involving the jaws. A 5-year-old boy was referred for swelling and pain in the left mandibular area. The patient showed diffuse swelling on the left side of the mandible and firm-moderate tenderness upon palpation. An intraoral examination showed moderate mobility and sensitivity to percussion on the left primary first and second molars, without severe caries. A radiographic examination revealed complete loss of the lamina dura on the left primary second molar and permanent first molar. There was a radiolucent osteolytic lesion and destruction of the cortical bone of the left mandibular body. Based on the clinical, radiographic, and immunohistochemical findings, the patient was diagnosed with BL, and was referred to a pediatrician for systemic evaluation and intensive chemotherapy. Even before the completion of chemotherapy, the swelling resolved and the displaced teeth were relocated to a normal position. This patient showed a good prognosis due to prompt diagnosis and intensive chemotherapy. Early diagnosis and referral for treatment can prevent the development of BL.

Dens evaginatus is a dental anomaly most commonly seen in premolar teeth in which a tubercle or protuberance projects from either the center of the occlusal surface or the buccal triangular ridge. These tubercles are easily fractured from mastication as the tooth erupts and frequently leads to pulp necrosis as a common complication. To prevent these sequelae, prophylactic treatment soon after the tooth starts erupting is essential. These preventive treatments include, selective grinding and protection of the tubercle by pit and fissure sealant. When the tooth does shows signs of pulp necrosis and apical periodontitis, endodontic procedures are needed. Apexification and apexogenesis are usually the treatment of choice for the affected teeth which have immature apices. Apexogenesis is a vital pulp therapy procedure performed to encourage continued physiological development and formation of the root end. It involves removal of the inflamed pulp and the placement of calcium hydroxide on the remaining healthy pulp tissue. This case report describes an atypical apexogenesis of a mandibular premolar which showed to be a dens evaginatus. The tooth which was treated with calcium hydroxide shows good results and is planned for permanent root canal filling.

Catamenial hemoptysis is a rare condition that's characterized by recurrent hemoptysis occurring in association with menstruation, and this is associated with the presence of intrapulmonary or endobronchial endometrial tissue. The diagnosis of pulmonary endometriosis can be made according to a typical clinical history and with exclusion of other causes of recurrent hemoptysis. Treatment of pulmonary endometriosis can be medical or surgical; however, the optimal management of this condition is still a matter of debate. Medical therapy may be problematic, due to recurrence of symptoms despite hormonal ablation, and adverse effects from long-term hormone therapy can also be a problem. We report here on a case of pulmonary endometriosis in a 23-year-old woman who presented with hemoptysis that occurred during the first 3 days of menstruation, and this happened over a 4 month period. She was successfully treated by video-assisted thoracoscopic surgery (VATS). No more hemoptysis was noted during 12 months of follow-up.
