The energy band structure of the quaternary material lattice matched to InP is calculated by the empirical pseudopotential metod(EPM) with another virtual crystal approximation(VCA). The calculated results are consistent with experimental values, where the dependence of the direct band gap of the lattice-matched to InP on Y is =0.83 + 0.777Y at X+Y=0.47.

Energy band structure of GaAs is calculated by the empirical pseudopotential method. The Lowdin-Brust perturbation theory is considered to reduce matrix size of the secular equation. For these calculations the matrix size(~15×15)is smaller than in the CB(~20×20) case and J.R.Chelikowsky et al. case(~30×30). Form factors are decided from reflectivity spectra, ultraviolet photoemission spectra(UPS) and x-ray photoemission spectra(XPS) data. Reflectivity data is well explained by these calcultions. When we extend the early calculations to lower energies into the valence bands, comparisons with UPS and XPS data show discrepancies. This discrepancies are considerably removed by replacing the free electron mass in the Hamiltonian with an effective mass.

The energy band structure of ternary compound semiconductor InAs1-xSbx is calculated by the empirical pseudopotential metod(EPM) with another virtual crystal approximation(VCA). The calculated results are consistent with experimental values, where the dependence of the direct band gap of the alloy InAs1-xSbx on X is Eg(X)=0.42-0.634X+0.464X².

환자의 x-ray 사진을 비롯한 각종 영상자료와 기타 진료 자료는 날로 그 量이 방대해져서 보관과 관리에 많은 문제점이 따르고 있다. 이에 경이적인 기억용량을 갖는 光 디스크 저장기술과 영상처리 기술, 근거리 네크워크 등이 통합된 영상 시스템을 이용하여 환자 정보를 좁은 공간에 보관하고 네트워크를 통해 필요한곳으로 전송할 수 있는 방법에 대해 고찰하였다. There has been many difficulties to store and transfer images and other data of patients. Because the amount of X-ray films and other data is so much and increasing day after day. Optical store would function similarly to a facility's film library, with the added benefits of reduced stored space, faster access time, and no loss of films. The entire imaging system could coexist on the network with the facility's hospital information system, allowing a complete integration of patient images, patient data records, and administrative functions.
