  • This paper shows that you can achieve high quality N+ emitter layers using a screen printable phosphorous diffusion paste and firing in an infrared belt furnace. Spreading resistance measurement from a beveled sample is used to measure carrier concentration as a function of depth for different phosphorous concentrations. Contours of estimated sheet resistance are shown for different processing conditions. This paper describes newly developed low cost phosphorous pastes. It shows the characterization of the newly developed phosphorous paste (DP99-038). This low cost pastes can easily be printed and make 16% efficiency.

  • The editorial department of Journal of Korean Neurosurgical Society[JKNS] polled more than 1,210 members of the Korean Neurosurgical Society[KNS] to evaluate the present status of JKNS from a viewpoint of readers or authors. The survey form includes questions about the impressions and opinions of JKNS regarding to its contents, style, and service. There responses were collected by means of e-mail and a total of 107 replies could be gathered during 2 months. Analysis of the responses revealed that majority of members of the KNS recognized the efforts to improve the quality of JKNS during recent years. However, there was also apprehensions and discontent about the quality of articles and review process in some KNS members.

  • It is generally recommended to use EVM as an efficient means for measuring project performance and progress so that the EVMS user could manage his project successfully. In spite of it's favorable intention, most project participants think it as a heavy load or a sub practiced job with low responsibility. Even though there are lots of variables triggering unpredictable troubles in EVM application, EVM still could be a valuable project health indicator. In this paper we introduce a performing method for EVM based on system engineering process.

  • The influence of the notch length on the stress distribution of mid-bondline and adherend was investigated using elasto-plastic finite element method. The results from the simulation showed that peak stress of mid-bondline decreased markedly as adherend with notch in the middle of lap zone, and the stress in the middle of joint with low stress originally increased evidently. All the peak stresses decreased firstly and increased again as the length of notch increased. The relative higher peak stress appeared at the point near the notch of adherend where might be failed previously during the loading procedure.

  • Recently new materials, such as fiber reinforced polymer(FRP) and other composite materials are being applied in reinforcing plate or plate or prestressing cables of concrete structures. Although these new materials themselves show the excellent durability and high strength, the bond behaviour between concrete surface and FRP is not well recognized. Therefore, this paper propose a evaluation method for effective bond length between fiber reinforced polymer(FRP) and concrete. To develop the evaluation method, this paper presents a review of current evaluation methods for effective bond length. These methods are compared by single face test, expose merits and demerits. And based on them, new evaluation method was developed. Finally, the new method was compared with existing methods to verify a adequateness for evaluation of effective bond length.

  • A new model and resultant equation for the coagulation of acrylonitrile monomers in precipitation polymerization are suggested in consideration of the surface tension (${\gamma}$) and cohesive energy density ($E_{CED}$). The equation was proven to be quite favorable by considering figure fittings from known surface tensions and cohesive energy densities of certain organic solvents. The relationship between scale value of surface tension (${\gamma}$/M) and cohesive energy density of monomers can be obtained by changing the coagulation bath component for effective precipitation polymerization of acrylonitrile in wet spinning.

  • Stibenequinone(SQ) derivative which was electronic transportation materials in Poly(N-vinylcarbazole) (PVK)-based on organic EL and an optical characteristic of organic EL which is mentioned previously was investigated. The Photoluminescence highest pick with blending TBSQ with PVK was shifted from 439nm to 517nm. This result indicates that an energy gap of a PVK/TBSQ blended sample is less than an energy gap of PVK. According to the electrochemistry characteristic, the ionization energy(Ip) and the electro affinity(Ea) decreased from 5.79eV to 5.63eV and 2.23eV to 2.63eV, respectively.
