The purpose of this study is to investigate the housing behavior through the code's housing history. The data were collected by open descriptive answering of 28 students in Y.University. The major findings are as follows: The characteristics of code's housing history were changed by stages of family life. The greastes changes are in the stage of elementary school(3rd stage). Before the 3rd stage, living in out of town, detached house, rental house is to superior than town(Dae Gu). Apt.. own house. And housing adaptation is to superior than housing adjustment. After 3rd stage go by contraies.

The aim of this paper is to mainly establish the sufficient and necessary conditions for the boundedness of the commutator ����Ω,b which is generated by the parameter Marcinkiwicz integral ����Ω and the Lipschitz function b on generalized Orlicz-Morrey space L��,��(Rd) in the sense of the Adams type result (or Spanne type result). Moreover, the necessary conditions for the parameter Marcinkiewizcz integral ����Ω on the L��,��(Rd), and the commutator [b,����Ω] generated by the ����Ω and the space BMO on the L��,��(Rd), are also obtained, respectively.

Road Deposited Sediment (RDS) is the solids formed from the wear of road, wear of vehicles, exhausts, and the input of the emissions from various sources out of the roads. RDS is seriously polluted by organic matter, nutrients, and metals. RDS plays an important role as the sink and the transport medium of the associated pollutants because RDS can be carried to the adjacent water system via stormwater runoff. In this regard, the heavy metals in RDS were investigated based on the publications. The contents of the metals in RDS were highly variable. The concentration of Cr, Ni, Cu, Fe, Zn, As, Cd, and Pb in urban RDS in various regions was in a range of 3.16-3,410, 1.15-1,382, 20.2-9,069, 2,980-124,853, 81-2,550, 2.3-214, 0.19-21.3, and 15.21-1,125 mg/kg, respectively. The anthropogenic enrichment of the metals in RDS was confirmed by the high concentration of Cu, Zn, Cd, and Pb. The contents of the metals were higher in industrial and traffic areas than in residential areas, while they were generally increased with decreasing particle size. It is believed that this study's results would contribute to quantifying the metals' load via RDS and establishing control strategies.

Electro_optical characteristics in AC-PDP are confined by a lots of parameters. especially driving pulse shape is very important to improve AC-PDP's luminosity and efficiency. In that experiment measure the luminosity, IR(Infra Red) peak value and response time as the increase of 1st, 2rd sustain pulse width. The VDS(Versatile Driving Simulator -developed by kwangwoon university-) was used to make driving pulse shape. It is found that IR response time after displacement current, Luminosity and IR peak value are changed on account of 1st,2rd sustain pulse width.

Purpose: This study was to identify health needs of the elderly at nursing homes by long-term care grade. Methods: The health needs of 116 elders at two nursing homes in Seoul were measured with resident assessment protocols (RAPs), activities of daily living (ADL), and cognitive performance scale (CPS), and pain and depression were measured by resident assessment instrument (RAI). Results: With regard to RAPs, 11 out of 18 items had different distribution in the 3 groups significantly. The 1st-grade elders had a higher percentage of 9 items than the 2nd- and 3rd-grade ones but the 3rd-grade ones had the highest health needs related with activity. The 2nd-grade elders had similar health needs to the 1st-grade ones. In terms of functional level, the 1st-grade elders had the highest percentage of CPS and ADL but the 3rd-grade ones had the highest score of pain and depression out of the 3 groups. The standardized assessment instrument to identify specific health needs by the 3 groups should be developed. Therefore, care plans to meet health needs of the 3 groups will be made. Conclusion: It is suggested that nursing care is required to the elderly of the 1st- and 2nd-grade and safe activity and environment to the 3rd-graded ones.

The issues in polysemy with respect to the verbs in WordNet will be discussed in this paper. The hypernymy/hyponymy structure of the multiple senses is observed when we try to build a bilingual network for Chinese and English. There are several types of polysemic patterns and a co-hypernym may have the same word form as its subordinates. Fellbaum (2000) dubbed autotroponymy that the verbs linked by mailer relation share the same verb form. However, her syntactic criteria seem not compatible to the hierarchies in WN. Either the criteria or the network should be reconducted. For most verbs in WN 1.7, polysemous relations are unlikely to extend over 3 levels of IS-A relation. Highly polysemous verbs are more complicated and may be involved in certain semantic structures. Semi-automatic sense grouping may be helpful for multimlinguital information retrieveal.

The rubber materials are widely used in automobile industry due to their capability of a large amount of elastic deformation under a force. Current trend of design process requires prediction of functional properties of parts at early stage. The behavior of rubber material can be modeled using strain energy density function. In this study, five different strain energy density functions - Neo-Hookean model, Reduced Polynomial $2^{nd}$ model, Ogden $3^{rd}$ model, Arruda Boyce model and Van der Waals model - were used to estimate the behavior of carbon black added natural rubber under uniaxial load. Two kinds of tests - uniaxial tension test and biaxial tension test - were performed and used to correlate the coefficients of the strain energy density function. Numerical simulations were carried out using finite element analysis and compared with experimental results. Simulation revealed that Ogden $3^{rd}$ model predicted the behavior of carbon added natural rubber under uniaxial load regardless of experimental data selection for coefficient correlation. However, Reduced Polynomial $2^{nd}$, Ogden $3^{rd}$, and Van der Waals with uniaxial tension test and biaxial tension test data selected for coefficient correlation showed close estimation of behavior of biaxial tension test. Reduced Polynomial $2^{nd}$ model predicted the behavior of biaxial tension test most closely.

This investigation was carried out to study the influence of pH and heat treatment on the ginsenosides in the white ginseng extract. Changes in ginsenosides (Rb1, Rb2, ,Rc, Rd) and free sugar were measured by the peak area variation of HPLC chromatogram during 25 hours heat treatment at the various level of pH. It was found that :(1) The peak areas of Rb1. Rb2, Rc and Rd on the HPLC chromatogram were decreased remarkably below pH 4.0 and more decrease was found as the temperature and heating time increased. (2) Those of glucose and arabinose were increased remarkably. It is considrered that the increase of glucose and the formation of arabinose result from the hydrolysis of ginsenoside( Rb1, Rb2, Rc, Rd) linked with sugars.

The selective migration, attachment and proliferation of periodontal ligament cells are the desired goal of periodontal regeneration therapy. Fibronectin is well known for an attachment protein for dentin surface. Also, Fibroblast growth factor (FGF) is well known to enhance the periodontal regeneration. The purpose of this study was to evaluation the effect of fibronection and FGF on the attachment rate and the cellular activity. Human gingival fibroblast and periodontal ligament cells were cultured from the teeth extracted for non-periodontal reson. Cultured human gingival fibroblast and periodontal ligament cells in vitro were treated with fibronectin and FGF a various dosage and culture times. Cellular activity was examined by MTT assay. The results of this study was demonstrated that cell attachment rate of experimental group was under the control value at 1st, 2nd, 3rd incubation day. But, at 3rd incubation day, attchment value tended to return to the control value. In case of fibronectin alone application, cellular activity was decreased than that of control at 1st, 2nd incubation day. But 3rd day, cellular activity was returned to the control value. The activity of gingival fibroblast in FGF alone application was decreased thatn that of control at each incubation day. But activity of periodontal cell group was increased cell activities at 2nd, 3rd day. Additionally cellular activity of fibronectin & FGF combined application on gingival fibroblast group was similar to control value at incubation day. But activity of periodontal ligament cell group was increased at 2nd, 3rd day compared with control group.This study demonstrated that combined application of fibronectin & FGF induced the selective chemotaxis for periodontal ligament cell in vitro.
