This study presents full vehicle dynamics model for the dynamic characteristic analysis of chassis parts which are suspension and brake system. This vehicle dynamics model is appled to kinematics and quasi-static analysis for each chassis part. In order to develop the vehicle dynamics model, the parameters of each chassis element part which are bush, spring and damper are measured by experiment. Also the wheel forces and moments of 6 DOF are measured at each wheel center. These data are applied to input parameter for vehicle dynamics model. And the verification of the developed model is achieved to comparison with the experimental force data of spring, trailing arm and assist arm by using the load response by strain gauge. These experimental force data are acquired by road test at event surfaces of P/G which are belgian and chuck holes roads.

A numerical study with Envi-met model is experimented to investigate the characteristics of wind pattern in Gangwon innovation city. In all case, most conditions such as wind speed, temperature, and surface are considered as the same, but wind direction is the only different factor. The wind directions considered in this study have a meaning of prevailing wind direction. When the prevailing wind with the direction of $247^{\circ}$ blows into the city, the ventilation passage toward the outside of city is formed and the stagnation of air is not expressed. In case of having the direction of $270^{\circ}$, most evident ventilation passages are composed. When the inflow wind direction is the north, $0^{\circ}$, there is some possibility of stagnation phenomenon. The case where the representative wind direction of three kind will flow with development, in compliance with the building is caused by with screening effect of some and shows a true stagnation phenomenon, wishes in the park and flowing water and the greens area to be for a long time formed and the wind direction is maintained.

The purpose of this study is to conceptualize the definition of school readiness specific to the context of the Republic of Korea. The school readiness test can be used as basic data to enable early childhood educational institutes to determine the general readiness of preschoolers and provide support to fit individual characteristics. For this purpose, six stages of the school readiness development process were considered, that is, draft development, primary preliminary survey, primary expert verification, secondary expert verification, secondary preliminary survey, and main survey. In the main survey, tests were conducted using the school readiness final draft targeting 344 preschoolers living in Seoul and Gyeonggi-do. The item discrimination power analysis and factor analysis for the examination area and question area were also conducted. Consequently, a test tool was developed on the basic of the results obtained, consisting of 129 items in the five areas of knowledge, function, adaptation, tendency, and attitude. The knowledge area was divided into general, linguistic, and mathematical knowledge, and the function area into fine motor function, basic living ability, expressive function, and gross motor function. The adaptation area was classified into adaptation activity, separation anxiety, maladaptive behavior, and environment adaptation; the tendency area into learning tendency; others understanding, and individual tendency, and the attitude area into rule compliance and life habits.

Purpose: To evaluate the effects of continuous self monitoring of blood glucose (SMBG) on glycemic control in diabetic patients. Methods: Among the diabetic patients who visited the department of internal medicine in H hospital from April 1 to October 27 2008, 76 patients were divided into the experimental group (n=39) and control group (n=36). The experimental group was required to measure blood glucose levels at least twice every other day using SMBG; their compliance was aided by weekly telephone reminders for 3 months after discharge. Glycated hemoglobin, fasting blood sugar and postprandial 2 hours glucose level, triglyceride and high density lipoprotein were measured before and after the study. Results: Baseline characteristics were not different between the experimental and control groups. Three months later, there was a significant difference in postprandial glucose between the two groups (t=-2.042, p=.045). Conclusion: There was significant improvement of glycemic control after the use of continuous SMBG, suggesting its value in strict glycemic control and the merit of an aggressive education program.

Dynamic as well as static and geometric design parameters such as inertia, tooth profile, backlash and clearance can be directly considered via multi-body dynamic analysis along with contact analysis. However, it is time consuming to use finite elements for the consideration of the tooth flexibility in the multi-body dynamic analysis of gears. A computationally efficient procedure, so called, Gear Stiffness Module, is suggested to resolve this calculation time issue. The characteristics of gear tooth compliance are discussed and rotational stiffness element concept for the Gear Stiffness Module is presented. Transmission error analyses for a spur gear system are carried out to validate the reliability and efficiency of the module. Compared with the finite element model, the Gear Stiffness Module yields considerably similar results and takes only 3% of calculation time.

The popularity of clear overlay retainers (CORs) has increased recently because of their advantages such as better esthetics, cost effectiveness, easy fabrication, and good compliance. However, a deficiency in posterior occlusal settling is a reported limitation of CORs. The aim of this study was to evaluate the posterior occlusal contact changes in a new type of clear orthodontic retainer called Oral-treaper (OTP), which consists of three layers and has stronger mechanical characteristics than do conventional retainers. Three patients who completed fixed orthodontic treatment received OTP as a removable retainer. Cast models were fabricated after the removal of fixed appliances (T1) and after 4 to 11 months of using the retainers (T2). We evaluated all the cast models to compare the post-orthodontic settling pattern during the use of the OTPs. The depth of occlusal contacts was evaluated using color maps. The OTP did not prevent vertical settling in all patients but resulted in an improvement in posterior occlusal contact points.

$M{\ddot{o}}nckeberg$ sclerosis is a disease of unknown etiology, characterized by dystrophic calcification within the arterial tunica media of the lower extremities leading to reduced arterial compliance. Medial calcinosis does not obstruct the lumina of the arteries, and therefore does not lead to symptoms or signs of limb or organ ischemia. $M{\ddot{o}}nckeberg$ sclerosis most commonly occurs in aged and diabetic individuals and in patients on dialysis. $M{\ddot{o}}nckeberg$ arteriosclerosis is frequently observed in the visceral arteries, and it can occur in the head and neck region as well. This report describes a remarkable case of $M{\ddot{o}}nckeberg$ arteriosclerosis in the head and neck region as detected on dental imaging studies. To the best of our knowledge, this is the first case that has been reported in which this condition presented in the facial vasculature. The aim of this report was to define the radiographic characteristics of $M{\ddot{o}}nckeberg$ arteriosclerosis in an effort to assist health care providers in diagnosing and managing this condition.

This paper is to examine some issues and policy direction of capital income taxation in Korea. Fundamental tax reform in US was reviewed to get some lessons for reforming the capital income taxation. One of main characteristics in Korea's capital income taxation is different treatment by corporation type, investment goods, and financial structures. Especially, the tax differential for debt and equity financing has been serious, as debt has been deducted as cost. We discuss that tax policy should try to satisfy the efficiency, equity, and simplicity under the structure of income based taxation for the time being. However, the changes of tax policies in advanced economies should be carefully examined, as Korea has the structure of small open economy. The current issue on the abolition of corporation income tax might be premature in logical structure and implementation. The US fundamental tax reform might be useful reference for determining the direction of capital income taxation in Korea, as it gives us some chances to discuss about tax base issue with income and consumption. Consumption based taxation is superior to income based taxation in the perspective of administrative and compliance costs. We should consider these tax costs for reforming capital income tax system in Korea.
