네티즌은 인터넷을 통해서 상품을 구매하고 상품에 대한 감정을 긍정 혹은 부정으로 상품평에 표현한다. 상품평에 대한 분석은 잠재적 소비자뿐만 아니라 기업의 의사결정에 중요한 자료가 된다. 따라서 인터넷의 대량 리뷰에서 의미 있는 정보를 분석하여 의견을 도출하는 오피니언 마이닝 기술의 중요성이 증대되고 있다. 기존의 연구는 대부분이 영어를 기반으로 진행되었고 아직 한글에 대한 상품평 분석은 활발히 이루어 지지 않고 있다. 또한 한글은 영어와 달라 꾸미는 말과 어미가 복잡한 특성을 갖고 있다. 그리고 기존의 연구는 통계적 기법, 사전 기법, 기계학습 기법 등을 사용하여 연구되었으나 인터넷 언어의 특성을 감안하지는 못하였다. 본 연구에서는 감정이 포함된 인터넷 언어의 특성을 분석하여 감정분석의 정확률을 높이는 감정분류 방법을 제안한다. 이를 통해 데이터에 독립적인 인터넷 감정기호를 이용해서 자동으로 긍정 및 부정 상품평을 분류할 수 있었고 높은 정확률, 재현율, Coverage 결과를 통해서 제안 알고리즘의 유효성을 확인할 수 있었다.

The purpose of this study was to provide basic data for nursing intervention in patient undergoing angiocardiography. Method: The subjects of this study were 60 patients undergoing angiocardiography. The data were analyzed using mean, percentage and pearson correlation Coefficient. Result 1) The mean score of the affective stress(anxiety) was $48.00{\pm}12.24$ and behavioral stress was $1.98{\pm}1.97$. The mean score of the physiologic stress(vital sign) was systolic pressure $124.10{\pm}17.72$, diastolic pressure $79.71{\pm}12.68$, pulse: $81.03{\pm}12.16$, respiration: $21.21{\pm}1.40$ 2) The mean score of the pain was $1.40{\pm}0.67.$ 3) There was a significant positive correlation between stress and pain. Conclusion : The result of this study show that stress is very important factor that effect on the pain therefore it will be considered stress in patient undergoing angiocardiography.

Consider a class of p(x)-Kirchhoff type equations of the form $$\left\{-M\left({\int}_{\Omega}\;\frac{1}{p(x)}{\mid}{\nabla}u{\mid}^{p(x)}\;dx\right)\;div\;({\mid}{\nabla}u{\mid}^{p(x)-2}{\nabla}u)={\lambda}V(x){\mid}u{\mid}^{q(x)-2}u\;in\;{\Omega},\\u=0\;on\;{\partial}{\Omega},$$ where p(x), $q(x){\in}C({\bar{\Omega}})$ with 1 < $p^-\;:=inf_{\Omega}\;p(x){\leq}p^+\;:=sup_{\Omega}p(x)$ < N, $M:{\mathbb{R}}^+{\rightarrow}{\mathbb{R}}^+$ is a continuous function that may be degenerate at zero, ${\lambda}$ is a positive parameter. Using variational method, we obtain some existence and multiplicity results for such problem in two cases when the weight function V (x) may change sign or not.

An 8-year-old, female lionhead rabbit with clinical sign of hematuria and vaginal discharge with/without blood was submitted to a local animal hospital. On exploratory laparotomy, three round to oval masses were observed in both uterine horns. The lumen of uterus was severely obstructed and distorted because of massive neoplastic proliferation. Histopathologically, the uterine masses revealed papillary projections along with irregular glandular structures into the lumen. The neoplastic foci were composed of numerous irregular sized neoplastic glands originated from uterine glands. These neoplastic cells showed very strong invasive tendency to muscle layer, therefore emboli of neoplastic cells were located in lymphatics. According to immunohistochemistry, the tumor cells in uterine masses demonstrated strong positive signals for cytokeratin, but negative for vimentin. Based on the gross, histopathologic and immunohistochemical features, this case was diagnosed as uterine adenocarcinoma in lionhead rabbit.

The forces acting on tractor three-point linkage were analyzed including the rear cover action of a rotary tiller which is ignored usually. The relation of link force and tillage resistance is expressed as a linear form. The link forces vary with tilling torque from negative force to positive in the free-link, though in the fixed-link they increase without change of force sign. The effects of the rear cover resistance appeared in the link forces in the fixed-link.

In the business environment which enclosed the domestic small and d medium distribution industry, and a business sign of recovery, reduction of income, job insecurity, and a national pension an aging society - positive exhibition of the large-sized store in comparison with the low personal consumption depended uneasy and deregulation, and consumer needs progress of individualization diversification it is ultimately faced with a difficult situation. Therefore the seen research examine the various range of a circulation policy through precedence research. It is going to consider and see the influence which the circulation regulation means of the purpose of large-sized store regulation and a major power is compared, and regulation.

A 4 years old male mixed breed dog, which weighed 25.5 kg, referred to Veterinary Teaching Hospital at College of Veterinary Medicine in Chonnam National University, because of chronic hindleg lameness. Click sound by flexion and extension of stifle joint, positive reaction by cranial drawer movement, fat pad sign and tibial position in cranial drawer position on the lateral radiographic view, medial patellar luxation (grade II), and lameness score 2.5 at standing and 2 at walking in right hindleg were showed. Under general anesthesia with enflurane, after medial arthrotomy, it was performed to remove remnants of cranial cruciate ligament and torn medial menisci and joint closed. In modified retinacular imbrication technique, one lateral fabellar/tuberosity suture, one medial fabellar/tuberosity suture, and one imbrication suture adjacent to the patella were placed. At 9 days after operation, lameness score 0 was observed and general condition was excellent.

End-milling is intermittent cutting process performed by a tool with a number of teeth. Its cutting forces are commonly measured by the tool dynamometer which has rectangular coordinates. In this case, the pattern of cutting forces is different according to cutting conditions. At a certain cutting condition, the sign of cutting force changes from positive to negative during a revolution of one tooth. The change of force direction excites a cutting tool and severe vibration arises when radial depth of cut increases. In this study, cutting experiments and simulations were carried out in order to explain the cause of the change of the cutting force direction. In addition, the effect of the cutting force change was discussed in terms of chatter vibration in end milling.

1989년 1월부터 1990년 2월까지 2년간 건강진단을 목적으로 본병원의 성인병예방센타를 방문했던 경상남북도 거주자 5,978명중 간흡충증 환자 528명을 대상으로 하여 낙동강유역 거주자와 나머지 지역 거주자의 감염율을 비교하였고, 같은 기간동안 본병원의 외래 또는 입원환자 중 간흡충증으로 진단된 206명의 복부초음파 소견을 분석하여 다음과 같은 결과를 얻었다. 1) 낙동강유역 거주자의 감염율이 나머지 지역 거주자에서 보다 3.8배 높았으며, 남녀의 비가 2 : 1이었고, 30세에서 59세 사이가 86%를 차지하였다. 2) 간내담관의 미만성 확장 및 여러정도의 간내담관벽의 에코증가와 아울러 담낭내의 떠다니는 뚜렷한 에코소견들이 간흡충증의 특징적 초음파 소견이며, 이중 간내담관의 확장으로 인한 parallel channel sign은 활동성 감염증이거나 또는 후유증일 수 있지만 담낭내에 떠도는 에코소견은 활동성 감염증을 나타내는 소견이다.
