An enzyme-linked immunosorbent assay (ELISA) with two Novirhabdovirus antigens (viral hemorrhagic septicemia virus, VHSV and infectious hematopoietic necrosis virus, IHNV) was used to detect specific antibodies against VHSV from olive flounder (Paralichthys olivaceus) sera. In ELISA plates with VHSV culture supernatants (VHSV-Ag plate), optical density (OD) values for sera from olive flounder with VHS history (VHS sera) ranged from 0.64±0.36, and those of sera from fish without VHS history (non-VHS sera) ranged from 0.26±0.26. In IHNV-Ag plate, the OD values (0.43±0.28) for VHS sera were quite low compared to those in VHSV-Ag plates, while the OD values for non-VHS sera were almost similar. When the OD values for each serum were calculated by subtracting the OD values in the IHNV-Ag plate from those in the VHSV-Ag plate, the corrected OD values were significantly different between VHS sera and non-VHS sera. The results were completely in line with fish histories of VHS epizootics. It was considered that the corrected OD values may represent the true values recognized by VHSV-specific antibodies.

Parry Romberg Syndrome (PRS), also known as idiopathic progressive hemifacial atrophy, is a rare neurocutaneous disorder characterized by loss of skin and subcutaneous fat of face, muscles, and bones causing unilateral atrophy. Most patients require only soft tissue augmentation although syndrome has varying grades of severity. In the majority of reported cases, it has been treated with surgical flap or autologous fat transplantation. However, these treatments need complicated surgical skills which take a lot of time and cost. Herein we report the first case of PRS augmented by hyaluronic acid (HA) filler in a 42-year-old female patient to suggest that HA filler could be a safe, simple, and even rational economic alternative to surgical treatment.

In this report, a case of a 70-year-old man with a large ganglion cyst formed after anterior transposition of the left ulnar nerve is presented. Three months after the index surgery, the patient presented with a painless superficial ovoid, soft mass measuring $5{\times}4{\times}2cm$ in size located at the posteromedial aspect of the left elbow, the previously operated site. Magnetic resonance imaging showed a well demarcated cystic mass with a stalk connecting to the elbow joint. Excisional biopsy was performed and pathologic findings showed that the cystic wall had no definite lining cells with myxoid degeneration compatible with findings of ganglion cyst.

In order to evaluate the relative significance of tolerance management of various elements in a VHS VTR tape transport system, the effect of geometric variations of the elements from standard design values on the tape traveling path is studied. The tape is modeled as a string and each element in the tape transport system is modeled as a cylinder whose radius, position vector and orientation vector are specified. An numerical algorithm is proposed to find the coordinates of tape entry points and tape exit points for the elements from which the tape traveling path can be completely described. By using the suggested algorithm, an error sensitivity analysis of tape traveling path due to the geometric variations of tape transport elements is performed for a particular model in the market and the elements demanding relatively strict tolerance management are identified.

The present study investigates the characteristics of fire-driven heat flows and gas concentration in a compartment fire by using the modified VHS model (MVHS). The main idea of this model is to add some source terms for combustion products and oxygen consumption to the original VHS model for providing more accurate and useful information on gas concentration distributions as well as thermal fields. It is found that the present MVHS model shows fairly good agreement with the experimental data and the eddy breakup combustion model. The tilting angle of fire plume calculated by MVHS is larger than that of EBU model because the fire source of VHS is affected by ventilating flow less than EBU. However, this discrepancy is apparently reduced in the downstream region of fire source.

Objectives: This study aimed to identify agreement between smartphone addiction (SA) and perceived SA among adolescents. Methods: This survey was done with 394 subjects conveniently sampled from elementary school (ES), middle school (MS), academic (AHS) and vocational (VHS) high school. The data were collected from June 20 to July 20, 2013 with self-administered questionnaire and analyzed by descriptive statistics, chi-square test and Cohen's kappa (${\kappa}$). Results: High risk of SA showed 2.8% in total, 1.0% in ES, 2.1% in MS, 4.1% in AHS, and 4.0% in VHS, which was statistically different by type of school (p<0.001). Perceived SA showed 22.6% in total, 9.0% in ES, 21.9% in MS, 33.7% in AHS, and 26.0% in VHS, which was statistically different by type of school (p=0.003). The agreement between SA and perceived SA was 82.0% (${\kappa}$=0.54) in total, 91.8% (${\kappa}$=0.53) in ES, 75.0% (${\kappa}$=0.33) in MS, 77.5% (${\kappa}$=0.53) in AHS, and 84.8% (${\kappa}$=0.65) in VHS. Conclusion: The agreement between SA and perceived SA showed moderate in general, but fair in MS. It is suggested to develop step-by-step activities to reduce the gap between SA and perceived SA among adolescen, in particular, middle school students.

Warthin's tumor is the second most common tumor of the parotid gland after pleomorphic adenoma. It is well known to occur as bilateral and multiple patterns. The incidence of extraparotid Warthin's tumor (EPWT) is about 2.7% to 12%, peri-parotid and upper cervical area are the most common sites. Warthin's tumor with synchronous intraparotid and extraparotid area is extremely rare, only a few cases have been reported. We report a-71-year old man with unilateral swelling of the parotid area and upper neck, pathologically confirmed Warthin's tumor with literature review.

Some clinical diseases, such as granulomatous thyroiditis, tuberculosis, and sarcoidosis can cause granulomatous inflammation in thyroid, and theses have various clinical presentations. Granulomatous thyroiditis is an inflammation of thyroid gland, and may be painful and tender in case of infection, radiation, or trauma. Otherwise, autoimmune conditions, medications, or an idiopathic fibrosis may cause to be a painless thyroididtis. It is self-limited, possibly viral, inflammatory thyroid disorder usually presented with thyroid pain and systemic symptoms. Tuberculosis of the thyroid occurs only rarely and the patient may be asymptomatic. In thyroid sarcoidosis, most common findings are painless, progressive enlargement of the thyroid with normal function. We have experienced a case of chronic granulomatous inflammation of thyroid gland presenting as a painless thyroid nodule and report it with a review of literature.

반월상 연골의 탈출은 슬관절 반월상 연골이 자기공명영상(magnetic resonance imaging, MRI) 사진의 관상면상 경골외측연에 대해 3 mm 이상의 전위를 보이는 경우이다. 그러나 이 소견을 관절경 하에서는 관찰하기는 어려운데 외측 반월상 연골의 관찰이 관절경 검사 시 슬관절 굴곡 상태에서 관찰되는 반면 자기공명영상(MRI)은 슬관전 신전 상태에서 촬영되는 차이점이 이유 중 하나이다. 이에 저자들은 관절경을 이용한 반월상 연골 탈출의 확인하는 방법에 대해 기술하고자 한다.

We examined the cause of a disease outbreak in adult olive flounder Paralichthys olivaceus, which occurred at a Korean aquaculture farm in Korea in 2011. The principal signs included an expanded abdomen and congested liver, with persistent mortality (a little over two months). At the beginning of the outbreak, farm administrators misjudged the disease as bacterial in origin, because of the aforementioned signs, persistent mortality, and the detection of bacterial species, including Vibrio spp. and Streptococcus spp. Moreover, the detection of viral hemorrhagic septicemia virus (VHSV) by reverse trasnscription-PCR analysis was complicated by use of the VHS-VN primer set, which has been in general use recently, because it produced weak bands in some samples. Therefore, we recommend the use of at least two different primer sets in the diagnosis of VHSV. Our histopathological findings indicate that necrotizing myocarditis could be considered a pathogenic sign of VHSV infection.
