Atmospheric aerosols play a crucial role for changing climate, resulting in a wide range of uncertainty for future climate prediction. In this paper we review current international research status and trend of climate-related aerosol science. There have been carried out a number of campaigns (including ACE-Asia, TRACE-P, ABC, and so on) and special experiments with some modeling studies over Korea, East Asia, and the Northwestern Pacific to characterize the various properties (physical, chemical, optical, and radiative) of Asian aerosols and evaluate their climate forcing impacts. But some parts of the aerosol research may need to be improved, advanced, or newly launched. Especially, a chemical transport model (CTM) embedded by a general circulation model (GCM) should be developed by the national scientific community with a high research priority, actively collaborating with international community in order to estimate direct and indirect global radiative forcing due to anthropogenic and natural aerosols.

Recently, ordinary mail is decreasing continuously by the development of ICT (Information and Communications Technology) including E-mail, messenger service, and etc. On the contrary, parcel post is increasing by the increase of online shopping, home shopping, and etc. Aside from these changes, the demand for various mail acceptance and delivery means is increasing with the increase of single households and dual-income couples. To overcome these environmental changes, Korea Post installs unmanned post offices which are composed of various unmanned mail acceptance and delivery postal systems. In this paper, we propose the methodological approach for the site selection of unmanned post office among the existing post offices and the installation standard of unmanned postal system considering the operation cost by the mail volume.

The rapid development of information technology has affected many industries, and made consumers receive new services that are completely different from those of the past. In the financial industry, various changes are taking place, such as providing the payment system which is easy to use and offering differentiated services. This study examined the factors affecting the intention to use mobile payment system. In particular, we considered both practical and emotional factors that affect the intentions. The mobile payment system, which is a new form of payment, is rapidly developing in China. In Korea, it is still in the beginning stage due to the legal regulations and the activation of alternative payment methods. This study, therefore, compared the differences in factors that affect the intention to use mobile payment system between Korea and China.

This study aims at exploring the characteristics of the Usonian houses of Frank Lloyd Wright from an ecological viewpoint. After considering the definition and application of ecological architecture through literature review, 28 Usonian houses were selected and analyzed for the study. Also, nine Usonian houses, which clearly have ecological and historical importance, were visited and more thoroughly analyzed. The result shows that Usonian houses are ecological in terms of 1) the relationship among nature, landscape and house, 2) the orientation, natural light and natural ventilation, 3) the use of natural local materials including wood, stones and bricks, 4) the use of floor heating (the On-dol system inKorea), 5) the human scale, 6) the use of the board and batten unit (an early system of prefabrication), and 7) the openness and flexibility of floor plans.

This paper focuses on recovering systematic biases during LIDAR calibration, particularly using natural surfaces as control features. Many previous approaches have utilized all the points overlapping with the control features and often experienced with an inaccurate value converged with a poor rate due to wrong correspondence in pairing a point and the corresponding control features. To overcome these shortcomings, we establish a preventive scheme to select the pairs of high confidence, where the confidence value is based on the error budget associated with the point measurement and the linearity and roughness of the control feature. This approach was then applied to calibraring the LIDAR data simulated with the given systematic biases. The parameters were successfully recovered using the proposed approach with the accuracy and convergence rate superior to those using the previous approaches.

Two spaniel dogs were presented with a history of lethargy, weakness, refractory hypoglycemia, and episodic seizure. A pancreatic mass on the distal end of the left limb was identified through screening tests including dualphase CT angiography in each patient. Canine insulinoma was suspected with low blood glucose, low fructosamine, and normal to high serum insulin levels. Exploratory laparotomies were performed, and partial pancreatectomy using an ultrasonic-activated scalpel was achieved without enzyme leakage or fistula formation after surgery. The lesions were definitively diagnosed as insulinoma via histopathologic examination. One dog has been doing well until POD 870 with medication; in the other dog, diffuse hepatic nodules noted during surgery were confirmed as a liver metastasis. This dog died at POD 45. This case report addresses the utility of the ultrasonic scalpel in partial pancreatectomy for the treatment of canine insulinoma and differences in prognosis according to disease stage.

This report describes a case of postpartum uterine rupture associated with retained placenta and sequential acute metritis, not dystocia. A 14-month-old Bichon Frise bitch presented with continuous vaginal bleeding. She delivered five puppies 3 days ago and expelled four placentas on the next day. After then, anorexia, acute depression with continuous vaginal haemorrhage developed. Plain radiography showed decreased serosal detail, and ultrasonography showed irregularly thickened uterine wall and ascites. Blood-tinged peritoneal fluid was an exudate with bacteria. Ovariohysterectomy was curative for the patient, and four full-thickness perforated holes were identified on both sides of the uterine horns.

As a nanotechnology has been actively applied to the overall areas of scientific fields, it is necessary to understand the characteristic features, physical behaviors and the potential effects of exposure to nanomaterials and their toxicity. In this article we review the immunological influences induced by several nanomaterials and emphasize establishment of the animal models to estimate the impact of these nanomaterials on development of immunological diseases.
