A network-based robot [1] is a robot that explores service servers in the network environment for analyzing sensor data and making decision. Since network-based robot architecture was proposed, it's possible to reduce costs of robots. We hope robots would be all around at home environment. Therefore, normal users who are not experts need to be able to control those robots by using easy commands. We developed a scripting language, named CCSLR, to help users and developers who control various robots in ubiquitous environment. We focused on how to design the common language for various robots and how to translate a CCSLR script into a sequence of low-level commands of the target robot. In this paper, we propose scripting methods, with three layers. The CCSLR system reads the profile information from the knowledge representation database. Users don't have to know all about kinematical and mechanical details of a robot. Then again, the CCSLR system will use the profile information to translate the script into separated executable library commands. The CCSLR system manages robot's changing state every time a robot executes a command.

Ventilation of the marine engine room is very important for the health of the workers as well as the normal operation of machines. To find proper ventilation conditions of this engine room, numerical simulation with standard k-${\epsilon}$ model was carried out. In the present study, the marine engine room is separated to two floors with porus horizontal partition and considered as a closed space with a heat source and forced ventilation ducts. The porosity of horizontal partition is found to be important. For the engine room with 2 supply ports & 2 exhaust ports, the increasing of the porosity of horizontal partition is effective to reduce the recirculation flow zone in the second floor. When the engine room is ventilated with three supply air ports & one exhaust port, the increasing of the porosity of horizontal partition is effective to reduce the recirculating flow zone in the exhaust air area, but there is a possibility of local extreme heating at the lower side of engine near bottom.

Personality characteristics of third decade female TMD patients was studied by means of SCL-90-R test. 112 TMD patients and 96 dental controls were subjected at the department of Oral medicine, Kyungpook National University Hospital. All the patients were divided into 3 groups according to their pain profile namely, MPDS, ID with Pain and ID with out Pain, and dental controls were divided into 2 groups manely, Dental Controls with Pain and Dental Controls without Pain for comparison. The obtained results were as follows : 1. Mean T-scores of SCL-90-R primary scales and global indexes in the patient and control group were within normal range. 2. When compared between groups with pain, MPDS group were significantly higher in scales of SOM, 0-C, I-S, HOS and PHOB than ID with Pain group and in scales of SOM, I-S. DEP, HOS and PHOM than Dental Controls with Pain group. 3. When compared with ID and Control groups in same pain condition, there were no significant differences between ID without pain and Dental Controls without Pain group. 4. When compared between groups with pain and groups without pain, there were significant differences in scales of SOM and O-C between Dental Controls with Pain and Dental controls without Pain group.

The present study was designed to determine the antitumor and antioxidant properties of methanol extract from the root of Galega purpurea (Papilionaceae) (MEGP) against Ehrlich Ascites Carcinoma (EAC) bearing Swiss albino mice. Acute and short-term toxicity studies were performed initially in order to ascertain the safety of MEGP. The effect of MEGP on the growth of transplantable murine tumor, life span of EAC bearing hosts and simultaneous alterations in the hematological profile and liver biochemical parameters (lipid peroxidation, antioxidant enzymes) were estimated. The MEGP showed decrease in tumor volume, packed cell volume and viable cell count and increases the nonviable cell count and mean survival time thereby increasing life span of EAC tumor bearing mice. Hematological profile reverted to more or less normal levels in extract treated mice. Treatment with MEGP decreased the levels of lipid peroxidation and increased the levels of glutathione, superoxide dismutase and catalase. The results suggested that the methanol extract of Galega purpurea root exhibited antitumor effect by modulating lipid peroxidation and augmenting antioxidant defense system in EAC bearing mice.

Retinoic acid (RA) evokes pattern duplication in the regenerating salamander limb. Interestingly, it also enhances dedifferentiation in the regenerate by the morphological, histological and biochemical criteria. To examine whether there is any correlation between the RA-evoked pattern duplication and de novo protein synthetic profile in the regenerating salamander limb, especially during dedifferentiation, we analyzed stage-specific protein synthesis pattern in the normal and RA-treated regenerating limbs by metabolic labeling followed by two-dimensional gel electrophoresis. In the regenerating limbs without RA treatment, a few hundred kinds of proteins were found to be synthesized at the stage of wound healing and the total number of protein synthesized increased greatly as regeneration proceeded. The same trend was also observed in the RA-treated regenerating limbs. Interestingly, some protein spots were noted to be either newly synthesized or highly expressed by the RA treatment especially at the stage of dedifferentiation. The results shows that the enhancement of dedifferentiation state after the RA treatment correlates well with the protein synthesis profile, and suggest that those proteins are important for the RA-evoked pattern duplication in the regenerating limbs of salamander.

The objective of this study was to assess the metabolic profiles and diet quality in college women by their mother's diabetes mellitus status. The study subjects, all college women, were classified into two groups based on the their mother's diabetes mellitus status: the offspring group (OG) and the control group (CG). The OG exhibited significantly higher body mass indices (p < 0.01), percentages of ideal body weight (p < 0.05) and high density lipoprotein cholesterol (p < 0.05) values than the CG. Additionally, the OG showed significantly higher daily average intakes of total energy (p < 0.05). fat (p < 0.001), riboflavin (p < 0.01) and calcium (0.01) than the CG. The indices of nutritional quality of protein (p < 0.05) and Na (p < 0.05) in the CG were significantly higher than those of the OG. However. we noted no significant differences in the mean adequacy ratio between the CG and OG. Overall, our results demonstrated that this factor appears to potentially be related to the subjects' mother's diabetes status. However, CG and OG were significantly different within normal range. Furthermore, nutrient adequacy indices in the CG were not assessed well in regard to energy, riboflavin, vitamin C, and calcium. Therefore, it appears that ideal body weight and diet quality should be controlled in order to prevent diabetes and diet-related problems, both in the CG and the OG.

Hexane, chloroform, methanol and water extracts of Paeoniae Radix were tested on the experimentally induced hypercholesterolemia in rats for lowering effect of serum lipoprotein contents. Hyperlipidemia was induced on male Wistar rats by feeding high cholestetrol diet for 7 days. Serum lipid profile was verified on these rats by measuring total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL), and low density lipoprotein cholesterol (LDL). Then, the diet was changed to normal. At the same time, hexane, chloroform, methanol and water extract of Paeoniae Radix were given orally on daily basis, and the changes in the serum lipid profile were assessed for 4 weeks. Methanol extract of Paeoniae radix decreased TC level at 1, 2, and 4 week point significantly, and water extract decreased TC level at 4 week point significantly comparing with the control group.

Solar-terrestrial links in short-time scales(daily ~monthly) are extensively explored in recent years: such as a response of low cloud amounts to the Forbush decrease, a response of Northern Atlantic oscillation index to sudden increase in electric field intensity of solar wind and so on (e.g., Svensmark et al., 2009; Boberg & Lundstedt, 2002). In this study, we perform the superposed epoch analysis to see any possible response of the sea-level pressure over Korean peninsula to the fast solar wind stream. Data sets are daily values, and zero days are determined to be days when the solar wind velocity exceeds 800km/s. Average profile of superposed sea-level pressure shows a gradual increase during the first 2 days and a decrease afterward below the normal level with a low pressure condition maintained for a few days. This result indicates that the sea-level pressure may respond to the fast solar wind stream. In other words, the average profile of sea-level pressure mimics the average velocity profiles. The correlation coefficient between two average profiles is 0.80, with 2 day lag.

The letters of the automobile tire are usually engraved on the side-wall. The shape of the side-wall is a sculptured surface generated by the rotational sweeping of a profile curve. The letters laid on the side-wall are usually designed by a 2-dimensional CAD. It is impossible to machine the letters on the surface accurately by 3-axis NC machining, because the axis of cutter should be tilted to align with the normal vector of the surface. In this case. the degree of freedom for the machine is at least four. This paper describes an idea for tool path generation of a 4-axis machine by using the 2-dimensional CAD data of the letters and the surface of the side-wall. This study includes the following procedures; (1) measuring the profile of the side-wall surface and curve-fitting of the measured points. (2) the 'non-parallel projection' of the letters on the side-wall, and (3) an inverse kinematics of the 4-axis lettering machine. Procedures in this paper are programmed in C-language on Windows95 environment. With a PC based CNC controller and a 4-axis lettering machine. these are tested sucessfully for the practical use.

Potential yield of micro wind turbine on the roof of urban high rise buildings is estimated. Urban wind profile is modeled as logarithmic profile above the mean building height with roughness length 0.8, displacement 7.5 m. Mean wind velocity from the meteorological agency data at the hight of 50m is used. Wind velocity changes are simulated on the rectangular roof of 26, 45, 53 degree pitch and the circular roof by computational fluid dynamics and RNG k-$\varepsilon$ turbulence models. Wind velocity increased approximately by a factor of the order of 270 % on the 26 degree pitched roof. In the 100 m and 200 m high buildings, wind enhancement is greater at the front side than at the center of the building. In the building arrangement model wind velocity changes abruptly and it becomes wind gusts. When commercial wind turbines are installed on the building roof, average power and annual power generation enhanced by 3~4 times than normal wind velocity at 50m and 6 kw wind turbine can generate 1053 kwh per month on the 26 degree pitched roof at 50m height and sufficiently supply electrical power with 15 household for common electrical use and food waste disposer. However, power output will vary significantly by the wind conditions in the order of $\pm$ 20 %.
