본 연구는 시계열분석 모형을 이용하여 농지임대료의 단기 예측을 실시하였으며, 분석 자료는 통계청에서 제공하는 1966년부터 2008년까지의 쌀 생산비 자료를 이용하였다. 농지임대료의 추정은 지수평활모형과 ARIMA모형을 적용하였다. 그 결과 지수평활모형에 비해 ARIMA모형이 농지임대료를 추정하는데 더욱 적합한 것으로 나타났다. 그리고 ARIMA 모형을 이용하여 농지임대료를 추정한 결과 2009년 262,529원에서 2013년 243,561원으로 나타났다. 본 연구를 통해 추정된 농지임대료는 농촌노인이 농지연금제도와 관계없이 추가적으로 확보할 수 있는 소득의 규모를 파악할 수 있을 뿐 만 아니라, 2011년부터 도입될 농지연금제도에 필요한 기초자료를 제공하는데 기여할 수 있을 것이다.

We report a case of 15 year-old female patient with a ossified chronic epidural hematoma. She had had head trauma 10 weeks previously and conservative care for delayed onset epidural hematoma at other hospital. Ossification was identified about 4 weeks after head injury and then progressed rapidly. We removed the chronic epidural hematoma with thick capsule and newly formed bone. The mechanism of the ossification associated with cephalhematoma and chronic subdural hematoma is reviewed and discussed.
Examining Visitation to the Gyeryongsan National Park

Understanding visit motivation to parks is important when attempting to improve visitor satisfaction and their intentions to revisit and recommend. The objective of this study is to not only examine the impact of visitors’ motivations on their satisfaction, but also study the effect of their satisfaction on their behavioral intentions. This objective will be fulfilled using regression models populated with data from the Gyeryongsan National Park (GNP). Onsite surveys were collected during April and May 2017 at the Donghaksa, Gapsa, Cheonjeong, Sinwonsa, Sangsin, and Sutonggol information centers of the GNP (N=224). The results of this study indicate that the visitors’ motivations influenced their visit satisfaction, which, in turn, impacted their behavioral intentions. The study’s findings will help park managers and policy-makers establish effective park management strategies and enhance visitors’ experiences.
Congenital Cavernous Sinus Cystic Teratoma

Teratomas represent 0.5% of all intracranial tumors. These benign tumors contain tissue representative of the three germinal layers. Most teratomas are midline tumors located predominantly in the sellar and pineal regions. The presence of a teratoma in the cavernous sinus is very rare. Congenital teratomas are also rare, especially those of a cystic nature. To our knowledge, this would be the first case report of a congenital, rapidly growing cystic teratoma within the cavernous sinus. A three-month-old boy presented with a past medical history of easy irritability and poor oral intake. A magnetic resonance image (MRI) scan of the head disclosed a large expanding cystic tumor filling the right cavernous sinus and extending into the pterygopalatine fossa through the foramen rotundum. These scans also demonstrated a small area of mixed signal intensity, the result of the different tissue types conforming to the tumor. Heterogeneous enhancement was seen after the infusion of contrast medium. However, this was a cystic tumor with a large cystic portion. Thus, a presumptive diagnosis of cystic glioma was made. With the use of a right frontotemporal approach, extradural dissection of the tumor was performed. The lesion entirely occupied the cavernous sinus, medially displacing the Gasserian ganglion and trigeminal branches (predominantly V1 and V2). The lesion was composed of different tissues, including fat, muscle and mature, brain-like tissue. The tumor was completely removed, and the pathological report confirmed the diagnosis of a mature teratoma. There was no evidence of recurrence. Despite the location of the lesion in the cavernous sinus, total removal can be achieved with the use of standard microsurgical techniques.

Objective : To analyze the radiosurgical results of intracranial meningiomas after Gamma Knife radiosurgery (GKS) and to assess the possible factors related to the outcome and complications in treating meningiomas. Patients and Methods : We retrospectively reviewed the clinical and radiological data in 179 patients(194 lesions) treated with GKS for intracranial meningiomas between May 1992 and October 2000. Radiosurgical responses were categorized as shrinkage, stasis and enlargement, and we defined the shrunken and static group as a radio-logical control. A Cox proportional hazards model was used to evaluate the correlation between the radiosurgical outcomes and various factors such as location and size of tumor, age and gender of patients, relation to venous sinus, pre-GKS degree of edema, treatment modality, radiosurgical parameters, and pathologic findings. Results : Patients were grouped into skull base meningiomas(57.7%), non-skull base tumor including convexity, parasagittal, and falx meningiomas(37.1%), and others(5.2%) according to the location of tumors. The mean maximum dose and the margin dose of tumor was 30.0Gy(19-45Gy) and 15.1Gy(9.5-24.5Gy), respectively. The mean volume of the tumors was 9.4cc(0.003-45.0cc). The radiologic control rate was 97.1%. The radiation induced imaging change with or without neurologic deficit was the most common complication(23.6%). There were seen mostly in convexity, parasagittal, and falx meningiomas which were deeply embedded in cortex. Conclusion : GKS for intracranial meningioma seems to be safe and effective treatments. However, GKS should be considered very cautiously in non-skull base tumor such as convexity, parasagittal, or falx meningiomas with regards to patient's age and general condition, size and location of tumor, pattern of embedding into cortex, presenting symptoms and patient's preference.
