Immigrant workers in Korea who have a multi-cultural background are increasing a need is arising to support them with housing that considers their housing culture. The purpose of this study is to gather information to formulate a plan of ChoSun-Tribe Immigrant Workers in Korea. For this purpose, we investigated to the usage of domestic space and the seating style of ChoSun-Tribe members in China and Korea. Ethnographic research with a questionnaire was used to analyze 16 households in China and 17 in Korea. The study results were as follows. 1. Most of the ChoSun-Tribe members in China and Korea thought that the kitchen had to be separated from other areas and also they wanted to have a large kitchen in which they can work comfortably. 2. ChoSun-Tribe members in China used a bathroom as a laundry normally while and ChoSun-Tribe members in China and Korea didn't think that a bathtub was indispensable in the bathroom. 3. The most uncomfortable feature for ChoSun-Tribe members in Korea was having to use a toilet outside so a toilet should be considered inside of the house. 4. ChoSun-Tribe members in China and Korea were accustomed to sitting on the floor for their living usually and ChoSun-Tribe members in China used the living room as a multi-purpose room for the family. 5. A modified Ondol system using water pipes under the floor was gaining popularity in China and was the most desirable heating system for ChoSun-Tribe members in China and Korea also. 6. ChoSun-Tribe members in China and Korea all took off their shoes inside of the house for hygienic reasons so the space for taking on-off shoes was indispensable. 7. Housing for ChoSun-Tribe immigrant workers in Korea needs to be planned with a good environment lots of sunshine and better ventilation.

This study aimed to verify the effects of estrogen on the onset and development of adolescent idiopathic scoliosis and the mechanisms associated with these effects by constructing a pubescent bipedal rat model. Experiments were conducted to investigate whether scoliosis progression was prevented by a Triptorelin treatment. One hundred twenty bipedal rats were divided into female, OVX (ovariectomy), OVX + E2, Triptorelin, sham, and male groups. According to a spinal radiographic analysis, the scoliosis rates and curve severity of the female and OVX + E2 groups were higher than those in the OVX, Triptorelin, and male groups. The measurements obtained from the sagittal plane of thoracic vertebrae CT confirmed a relatively slower growth of the anterior elements and a faster growth of the posterior elements between T11 and T13 in the female and OVX + E2 groups than in the OVX and Triptorelin groups. Histomorphometry and immunohistochemistry revealed a significantly longer hypertrophic zone of the vertebral cartilage growth plates that expressed more type X collagen and less type II collagen in the OVX and Triptorelin groups than in the female and OVX + E2 groups. Ki67 immunostaining confirmed an increase in the proliferation of vertebral growth plate chondrocytes in the OVX group compared with the female and OVX + E2 groups. In conclusion, estrogen obviously increased the incidence of scoliosis and curve severity in pubescent bipedal rats. The underlying mechanism may be a loss of coupling of the endochondral ossification between the anterior and posterior columns. Triptorelin decreased the incidence of scoliosis and curve magnitudes in bipedal female rats.

This paper addresses development of the ultra-light analog sun sensors for small satellite applications. The sun sensor is suitable for attitude determination for small satellite because of its small, light, low-cost, and low power consumption characteristics. The sun sensor is designed, manufactured and characteristic-tested with the target requirements of ${\pm}60^{\circ}$ FOV (Field of View) and pointing accuracy of ${\pm}2^{\circ}$. Since the sun sensor has nonlinear characteristics between output measurement voltage and incident angle of sunlight, a higher order calibration equation is required for error correction. The error was calculated by using a polynomial calibration equation that was computed by the least square method obtained from the measured voltages vs. angles characteristics. Finally, the accuracies of 1-axis and 2-axes sun sensors, which consist of 2 detectors, are compared.

Daylighting systems can improve the luminous quality of indoor environment and reduce the building's electric lighting energy consumption. For designing good daylighting, place the light where it is desired and avoid excessive contrasts, glare and high light levels. Sun scoop, light scoop and sun catcher systems have been used for alternative systems compared to other natural lighting systems. This study aims to evaluate daylighting performance of sun scoop, light scoop and sun catcher systems using scale model experiments. For the purpose, the 1/10 scale models of the systems were made as the same areas of glazing(10 percent of floor area) on the top of the center roof. Totally 15 measuring points of illuminance on the horizontal work plane were monitored from 09:30 to 12:30 on October 29, 2007. Agilent data logger and photometric sensors Li-cor were used. As the results, the topside lighting systems can improve the illumination uniformity than side lighting and top lighting. However, the appropriated shading system should be integrated to prevent the direct sunlight.

Heliostat, as a mirror system tracking the sun's movement, is the most important subsystem determining the efficiency of solar thermal power plant. Thus the accurate sun tracking performance under the various hazardous operating condition, is required. This study presents a methodology of development of the solar ray tracing technique and the application of it in the analysis of sun tracking error due to the heliostat geometrical errors. The geometrical errors considered here are the azimuth axis tilting error and the elevation axis tilting error. We first analyze the geometry of solar ray reflected from the heliostat. Then the point on the receiver, where the solar ray reflected from the heliostat is landed, is computed and compared with the original intended point, which represents the sun tracking error. The result obtained shows that the effect of geometrical error on the sun tracking performance is varying with time(season) and the heliostat location. It also shows that the heliostat located near the solar tower has larger sun tracking error than that of the heliostat located farther.

Diabetic ketoacidosis (DKA), a fatal acute diabetic complication, is characterized by severe metabolic decompensation and intravascular volume depletion. These conditions may result in hypercoagulability and prothrombic state. Pulmonary thromboembolism (PTE) could be presented as an uncommon and life-threatening complication of DKA. Reported herein is a case involving a 54-year-old male patient who was admitted with DKA due to chronic alcohol consumption and stopping the intake of oral antidiabetic drugs. After low-molecular-weight heparin and warfarin treatment because of PTE during the DKA treatment, the patient's condition improved over the week that he was discharged on insulin and warfarin.

The feasibility of reduction of sodium intake using sun-dried salt and monosodium glutamate (MSG) was studied. Preference test was performed to evaluate the sensory properties of bean-sprout soup and vegetable rice porridge soup. Sun-dried salt and MSG might be a partial substitute for refined salt. There was a significant difference in salt taste strength between sun-dried salt and refined salt. Sun-dried salts 0.45% with MSG 0.07% resulted in the highest taste preference compared to that of sun-dried salts 0.60% without MSG in bean-sprout soup, which resulted in 23.9% reduction of sodium intake. Sun-dried salts 0.38% with MSG 0.04% resulted in the highest taste preference compared to sun-dried salts 0.53% without MSG in vegetable rice porridge soup, which resulted in 25.4% reduction of sodium intake. There seemed to be a synergistic effect on reduced usage of sodium salt when MSG was used in vegetable rice porridge and bean-sprout soup with sun-dried salt.

Background and Aims: Hepatitis B virus (HBV) reactivation was reported to be induced by transcatheter arterial chemoembolization (TACE) in HBV-related hepatocellular carcinonma (HCC) patients with a high incidence. The effective strategy to reduce hepatitis flares due to HBV reactivation in this specific group of patients was limited to lamivudine. This retrospective study was aimed to investigate the efficacy of prophylactic entecavir in HCC patients receiving TACE. Methods: A consecutive series of 191 HBV-related HCC patients receiving TACE were analyzed including 44 patients received prophylactic entecavir. Virologic events, defined as an increase in serum HBV DNA level to more than 1 log10 copies/ml higher than nadir the level, and hepatitis flares due to HBV reactivation were the main endpoints. Results: Patients with or without prophylactic were similar in host factors and the majorities of characteristics regarding to tumor factors, HBV status, liver function and LMR. Notably, cycles of TACE were parallel between the groups. Ten (22.7%) patients receiving prophylactic entecavir reached virologic response. The patients receiving prophylactic entecavir presented significantly reduced virologic events (6.8% vs 54.4%, p=0.000) and hepatitis flares due to HBV reactivation (0.0% vs 11.6%, p=0.039) compared with patients without prophylaxis. Kaplan-Meier analysis illustrated that the patients in the entecavir group presented significantly improved virologic events free survival (p=0.000) and hepatitis flare free survival (p=0.017). Female and Eastern Cooperative Oncology Group (ECOG) performance status 2 was the only significant predictors for virological events in patients without prophylactic antiviral. Rescue antiviral therapy did not reduce the incidence of hepatitis flares due to HBV reactivation. Conclusion: Prophylactic entecavir presented promising efficacy in HBV-related cancer patients receiving TACE. Lower performance status and female gender might be the predictors for HBV reactivation in these patients.
