Esophageal diverticulum is a rare entity, the true incidence of which is unknown, mainly because there are usually no clinical symptoms. Most esophageal diverticulum are found incidentally during an endoscopic or radiologic examination. Their classification is based on anatomical location; namely, upper third(Zenker or pharyngoesophageal), middle third(thoracic), or lower third(epiphrenic). Here we report a 52-years-old female presenting with dysphagia and regurgitation. Esophagogram showed esophageal diveticulum at lower cervical esophagus. Its positional aspect, it is different from Zenker's diveticulum. Treatment is surgical via an endoscopic or external approach. In view of the patient's age and anatomical location, various surgical approaches were considered as a therapeutic option for the management. This paper presents our experience in the management of esophageal diverticulum which was unusual location and stapled open resection without sternotomy.

Sinonasal malignant tumors comprise less than 1% of all cancers and 3% of all malignant tumors of the head and neck, which explains a lack of large series addressing the clinical characteristics and management of these tumors. Neck node metastasis occurs in only about 7% to 15% of malignant tumors compared with other head and neck cancers. A 90-yr-old woman presented with left palpable neck mass and right nasal mass occupying nasal cav-ity. Fine needle aspiration biopsy of left neck mass results in metastatic squamous cell carcinoma(SCC). PET/CT shows intense FDG uptake in right nasal cavity with bone invasion. Histopathologic examination of excised lesion in the right nasal cavity revealed SCC. We report here on a primary sinonasal SCC with contralateral lymph node metastasis.

This study aims to estimate spatial dependence for rice production yield among eight provinces in South Korea. Student’s T copula is used to estimate the spatial dependence and tail dependence. Yearly historical rice production yield data(1960-2016) for eight provinces are de-trended and normalized as year 2016 to estimate spatial dependence and tail dependence. The result shows that rice production yields for most provinces are strongly correlated to each other. Also, tail dependence shows a strong relationship for each other except some provinces. This implies that crop insurance programs should be partly supported by government due to the possibility of high systemic risk. In addition, regional production yield risk modelling imposing the spatial dependence is proper than an unified aggregate risk modelling.

The price of fresh meats have been severely fluctuated with the increased incidents caused by livestock diseases in these days. Many consumers suffered from unfavorable economic condition recognize the price fluctuation of fresh meats as a main source of the increase in general price. However, the general price are affected by the interaction of all products within an economic system. This study aims to examine the effect of a price change in fresh meats on the general price level and consumer price index (CPI) using Input-Output (IO) model that shows the interaction among industries in a country. The results show that the price change in fresh meats has a limited effect on the general price level and CPI. In addition, its effects are trivial compared to that of public sector.

본 구현의 배경은 도어록을 이용한 범죄에 사람들이 노출되어 있다는 점에 주목했다. 기존 도어록들은 숫자 키 패드, 카드 인식, 열쇠로 이루어져 있다. 이러한 시제품들은 지속적인 범죄의 노출로 인해 보안성이 우수하지 못하다. 또한 기존 시제품인 얼굴인식 도어록은 일반 사용자들이 구매하기에는 고가에 판매되고 있기 때문에 접근성이 떨어진다는 단점이 있다. 따라서 본 구현에서는 사용자들이 라즈베리파이 모듈, 카메라 모듈, 라즈베리파이 터치스크린, 서보모터로만 구성되어 있는 얼굴인식 기반 자동 도어록을 통해 소비자의 접근성을 높이고 개인 고유의 얼굴인식 키(Key)를 통해 보안성의 이점을 동시에 가져갈 수 있는 얼굴 인식을 이용한 자동 도어록을 제작하였다.
