This study explored factors influencing socialization of child care. Political ideology and age were found as major predicting factors of socialization of care. Age, especially, was confirmed as an important predicting factor of socialization of care. Also, those with more progressive political ideology had the higher level of socialization of care. This finding reassured that socialization of care were considered as political issues in Korea. Income did not predict socialization of care, although it is said that a tax increase provoked conflicts between socioeconomic classes. Issues of caring were shared among people regardless of income levels. Therefore, specific interventions are necessary for preventing caring issues from using as a political lever, overcoming value differences between generations, and promoting social integration.

The purpose of this study was to find out how diagnosis of hyperlipemia differed for according to BMI and %Fat. The included subjects were 224 adult women, they performed physical measurement and BMI measured %Fat by BIA. Blood pressure and lipid profiles were measured in the NPO state. The LDL calculated in using a formula of Friedwald and an atherogenic index was calculated using the serum TC lever divided by th HDL level As a results, HDL decreases so that BMI and %Fat increase and TC, TG, LDL, AI appeared by increasing. There was significant correlation(r=.585) between BMI and %Fat, and lipid profile correlation with BMI is higher than %Fat. In conclusion, diagnosis results of hyperlipemia according to BMI and %Fat could become different conclusively. In study it seems that BMI's diagnosis ability on hyperlipemia is high but the most desirable method uses BMI and %Fat together and evaluates lipid profile.

In this paper, we proposed a liver extracting procedure for computer aided liver diagnosis system. Extraction of liver region in an abdominal CT image is difficult due to interferences of other organs. For this reason, liver region is extracted in a region of interest(ROI). ROI is selected by the window which can measure the distribution of Hounsfield Unit(HU) value of liver region in an abdominal CT image. The distribution is measured by an existential probability of HU value of lever region in the window. If the probability of any window is over 50%, the center point of the window would be assigned to ROI. Actually, liver region is not clearly discerned from the adjacent organs like muscle, spleen, and pancreas in an abdominal CT image. Liver region is extracted by the watershed segmentation algorithm which is effective in this situation. Because it is very sensitive to the slight valiance of contrast, it generally produces over segmentation regions. Therefore these regions are required to merge into the significant regions for optimal segmentation. Finally, a liver region can be selected and extracted by prier information based on anatomic information.

Conjugated linoleic acid(CLA) is a naturally occuring group of derivatives of linoleic acid found in beef and dairy products. CLA has reported to reduce body fat. This study was designed to observe the effect of CLA supplementation on fat accumulation and degradation in male Sprague Dawley rats. Seventy two rats, weighing 150-180g, were divided into 2 groups according to the types of dietary fat(beef tallow or fish oil) and then each group was divided into 2 groups depending on CLA supplementation, i.e., BT, BT-CLA, FO, FO-CLA. All rats were fed experimental diet containing total fat at 12%(w/w) including CLA at 1% for 30 weeks. At 30 weeks, rats were sacrificed to measure TG, free fatty acid level in plasma, TG, lipogenic enzymes in lever and fat cell size, LPL and HSL activities in epididymal fat fad. Fish oil supplemented with CLA diet showed significant reduction in the food efficiency and weight in 30 weeks-fed rats. CLA supplement did not effect on plasma TG, hepatic TG levels and lipogenic enzymes activities in rats, but, fish oil significantly reduced, The LPL and HSL activities did not affected by CLA supplement and n-3 fatty acid rich fish oil. In conclusion, the results suggest that CLA supplement was not a proper way to reduce the fat accumulation in Sprague Dawley rats. Fish oil supplemented with CLA might better way to reduce the body fatness than fish oil itself. Therefore, It is recommended that further study be performed related to physiological and biochemical effects of CLA supplementation and n-3 fatty acid in rats for the reduction of body fatness.(Korean J Nutrition 34(4) : 367∼374, 2001)

Skin temperatures, heart rates and skin conductance levels were tested in order to extract the biological characteristics of the physical constitutional types in according to the Lee's 4 type physical constitutional theory. The subjects of this experiment were 14 ; 5 Macro-Negative subjects, 5 Micro-Negative subjects, 3 Micro-Positive subjects and 1 Macro-Positive subject. All subjects were stimulated with 2.5Hz 30V peak-peak pulses for 2 minutes. As the results, in normal prestimulation state the skin temperatures of the trunk in Micro-Positive and Macro-Positive subjects were higher than those of Macro-Negative and Micro-Negative subjects. In Macro-Negative subjects the reflected skin temperature of lever was the highest in the anterior trunk. In Micro-Negative subjects the reflected skin temperature of kidney was the highest in the trunk. In Micro-Positive subjects the reflected skin temperature of stomach was the highest in the trunk. In Macro-Positive subject the reflected skin temperature of lung was the highest in the trunk. In transient poststimulation state, heart rate was decreased in 7 cases among of 10 Macro-Negative and Micro-Negative subjects, but it was iscreased in 3 cases among of 4 Micro-Positive and Macro-Positive subjects. And the hand temperature was increased in 8 cases among of 10 Macro-Negative and Micro-Negative subjects, but it was decreased in 3 cases among of 4 Micro-Positive and Macro-Positive subjects.

In the middle of motorization, the traffic problems become serious social problems in Korea. The walking environment is not only a topic which restores the community spirit of a city or society but also a lever which renovates the future space of the city environment-friendly. Thus, the Purpose of this study is to suggest the new criteria of walkway level of service adopting the concepts of safety. convenience, comfort, environment, security, and continuity in addition to present pedestrian flow rate, and to provide basic data for walkway plan in Korea. In order to analyze the adequacy of the present walkway level of service criteria, the walkways of which service levels were A, C, E according to USHCM were selected as study walkways, and an interview surrey was conducted to compare the three service levels with those that pedestrians evaluate actually. Also, another interview survey was conducted to analyze the service conditions and satisfaction level at the walkways of high service levels(A and B). For the establishment of more reasonable walkway level of service criteria. the survey of pedestrian\`s consciousness for walkway service was conducted. Based on the survey results, the new criteria for the evaluation of walkway service were selected and the six levels of service for each criterion was analyzed: so the comprehensive criteria of walkway level of service were suggested.

In this paper, a simplified Cubature Kalman Filter (SCKF) is proposed to reduce the computation load of CKF, which is then used as a filter for transfer alignment of shipboard INS. CKF is an approximate Bayesian filter that can be applied to non-linear systems. When an initial estimation error is large, convergence characteristic of the CKF is more stable than that of the Extended Kalman Filter (EKF), and the reliability of the filter operation is more ensured than that of the Unscented Kalman Filter (UKF). However, when a system degree is large, the computation amount of CKF is also increased significantly, becoming a burden on real-time implementation in embedded systems. A simplified CKF is proposed to address this problem. This filter is applied to shipboard inertial navigation system (INS) transfer alignment. In the filter design for transfer alignment, measurement type and measurement update rate should be determined first, and if an application target is a ship, lever-arm problem, flexure of the hull, and asynchronous time problem between Master Inertial Navigation System (MINS) and Slave Inertial Navigation System (SINS) should be taken into consideration. In this paper, a transfer alignment filter based on SCKF is designed by considering these problems, and its performance is validated based on simulations.

This paper explores a real-time system implementation to couple tightly StrapDown Inertial Navigation System(SDINS) and Global Positioning System(GPS) mounted on the aircraft. When implementing the SDINS/GPS coupled system in real-time processor, we have to deliberate SDINS's unique characteristics based on the ring laser gyro, and besides, lever-arm, measurements, and error compensation method. The novel modeling method is applied to system the misalignment error term of gyro to estimate the cumulative heading attitude errors while the aircraft banking to turn repeatedly. Captive Flight Test results show that the proposed modeling strategy has good performance.
