Although human-sized bipedal humanoid robots have been developed as the ideal form of human-friendly robots, studies of humanoid robots from the user perspective and of actual interaction between humanoid robots and the public in daily environments are few. This paper presents a long-term public demonstration that encouraged interaction between a humanoid robot and unspecified individuals. We have collected a significant amount of subjective evaluation data from the public by performing a storytelling demonstration that enhanced people's empathy towards the robot. The evaluation model consists of the robot's human friendliness, which involves its impression on humans, interaction with humans, and imitation of human motions and the robot's human appearance which involves gender, age, height, and body type. This study shows that there is no significant difference in human-friendliness between gender groups (male and female), while there is a significant difference between age groups (children and adults). In human appearance, it appears that there is no significant difference between either gender groups or age groups, except for the case of the robot's height.

A mobile tour-guide robot is a very attractive tour-guide in the exhibition hall of science museums and the necessity of tour-guide robots for museums is gradually increasing. Two kinds of robots have served as tour-guide robots in an exhibition hall of the Korea National Science Museum which is a very densely populated museum of many people and exhibits. The robots move around the large exhibition area and provide guide services to lots of visitors. A robot leads the way to the exhibit that a visitor wants to find and it takes the shortest route. Robots were operated for four months from January to April 2011, and we observed behavior of visitors and collected subjective evaluation of users. The result shows that there are four stages of using a mobile tour-guide robot and some differences of subjective evaluations depending on the gender and the age of the user and we suggest several improvements on the mobile tour-guide robot.

Detailed characteristics of the mean flow field inside the rotor of a multiblade fan with scroll are presented in this paper by measurements and visualizations. The measurements were taken with a five-hole probe and conformed by smoke test. How field is distinguished clearly in 3 regions with respect to the flow directions. The first region is near the exit of scroll where the fluid flows the opposite direction to the rotation of rotor. The second is opposite side of the scroll exit where the fluid flows the same direction to the rotation of rotor. The third is the region where the fluid flows toward the blades directly with the largest values comparatively. The strongest recirculation is happened in the second region, and the weakest one is in the third region. This complex configuration makes the flow field highly non-uniform and may cause to generate a noise and ineffective flow efficiency.

Pancreatic cancer is commonly presented with distant metastasis. However metastasis to central nervous system (CNS) of pancreatic cancer was rarely reported. 79-years-old man was hospitalized with sudden onset right arm dysesthesia and weakness. In brain magnetic resonance imaging, multifocal high signal intensity lesions in cerebral and cerebellar cortices were observed. Leptomeningeal and parenchymal enhanced lesions were also noted in contrast-enhanced T1 images suggesting a metastasis from the pancreatic cancer. Stroke like manifestation of CNS metastasis of pancreatic cancer is extremely rare. Careful history taking and evaluation should be performed to find the origin of the sudden neurologic deficit.

A 59-year old man was admitted for drowsiness and stiff neck. CSF examination showed lymphocytic pleocytosis and PCR for herpes simplex virus (HSV)-1 was positive in CSF. Brain MRI revealed enhanced lesions in left temporal lobe. His symptom improved with acyclovir. Follow-up studies showed red blood cells in CSF and a hematoma in the left temporal lobe. There was no additional symptom related to the hematoma. He was discharged after conservative care. Although rare, hematoma can develop in HSV-1 meningoencephalitis.

Assessment regarding the nutritional status of Parkinson's disease (PD) patients is important because their nutritional status influences the outcome of disease. The purpose of this study investigated the dietary habits, dietary quality, and quality of life for Korean PD patients according to their nutritional status. Seventy PD patients were recruited from K University Hospital (KMC IRB#0918-07) from February 2010 to October 2011. To diagnose PD, the United Kingdom Parkinson's Society Brain Bank standards were used by a neurology physician. The participants were interviewed and assessed using various tools, including a general questionnaire, anthropometrics, questionnaires for dietary habits, dietary diversity score (DVS), dietary variety score (DVS), diet quality index-international (DQI-I), beck depression inventory (BDI), the Korean version of mini mental state examination (K-MMSE), and 36-item short-form health survey (SF-36). The results of the study were as follows: 1) Most of the PD patients (69.0%) were at risk of malnutrition, and 8.5% and 22.5% of the subjects were malnourished and well-nourished, respectively. 2) Clinical symptoms (swallowing and chewing difficulties) were obvious, and the quality of diet (DDS, DVS, DQI-I) was low in the malnourished group (p < 0.01). 3) The malnourished group had significantly lower scores regarding SF-36 (quality of life) as well as that of cognitive function (p < 0.05). 4) The nutritional status of PD patients was significantly correlated with their depression (p < 0.05) and quality of life (p < 0.01). These results indicate that appropriate nutritional management will improve the nutritional status and quality of life as well as the cognitive function in Parkinson's disease patients.

Ovarian hyperstimulation syndrome (OHSS) is a potentially serious complication occurring in ovarian induction therapy. We report a case of ischemic stroke with OHSS. Previously healthy 33-year-old woman underwented In vitro fertilization-Embryo transfer (IVF-ET) 6 days ago. She admitted for dyspnea and abdominal distension. Chest X-ray arid simple abdomen showed massive pleural effusion and ascites. Left hemiparesis and sensory extinction were developed suddenly 2days after admission. She was administrated with recombinant tissue-plasminogen activator (rt-PA) intravenously witin 3hours of symptom onset. Hemiparesis was improved remarkably after rt-PA infusion. Magnetic resonance imaging showed acute ischemic infarction on the right basal ganglia, corona radiata, temporal lobe and parietal lobe, and left frontal lobe, and parietal lobe. Laboratory studies showed Hemoconcentration (hematocrit: 50.4%), elevated D-dimer and fibrinogen (5.03 μg/mL and 406 mg/dL respectively) and decreased protein S activity (51%). 20 days after admission, she discharged without neurologic sequelae. Screening test for hypercoagulable state should be considered before ovulation induction therapy to prevent cerebrovascular complication with OHSS.
