The well defined prominent high cheek bones is classically a sign of beauty in western culture, since the ideal facial configuration is oval and persons with high cheek bones seem to retain their youghful appearance longer than average. But in our cultural background, the persons with prominent malar regions may be unlucky or unfortunate during her or his life andso want to reduce prominent malar regions. We performed reduction malarplasty with various approach methods in 6 patients who complained prominent malar regions with or without prominent zygomatic arch area, and after the operation the patients were satisfied with the results. This article present materials, preoperative check, operative method, result and discussion for the following malarplasty.
PHOTOMETRIC OBSERVATIONS OF BW VUL
Jung, Jae-Hoon,Lee, See-Woo The Korean Astronomical Society 1985 Journal of The Korean Astronomical Society Vol.18 No.1
We present the data of photoelectric photometric observations of BW Vul carried out for four nights during the period of $1982{\sim}1984$. The light curves with asymmetric shape show a stillstand on the ascending branch at phase of ${\phi}{\approx}0.85$ just before the maximum light, and also the ampitude and shape of light curves are changed from night to night. Using all the published data, a new ephemeris of maximum time is derived, in which the period of light variation is $P=0^d.20102977$ and its increasing rate is 2.2 see/century.

The purpose of this survey was to obtain information about the status. attitudes and values KNUPE' 1996 freshmen. A questionnaire was administered to 345 KNUPE freshmen. Data was analyzed by SPSS, a computer statistical package and the results of comparing the responses to each question with respect to sex and department were presented. The conclusions obtained from the results and discussions of this study are as follows: First, freshmen could be categorized into two groups having different views towards university life and in their plans for the future. Therefore the faculty and staff should take these into consideration when they establish university policies. Second, great concern was shared by many with regards to their career and systematic help is needed to develop mature occupational identity. therefore, the student guidance center is planning to introduce a group counseling program starting in the spring of 1997. This study is limited because the survey had a low response rate. It is imperative that the faculty and staff be more cooperative in this survey to better understand the interest of all students.

<P><B>Abstract</B></P> <P>In recent years, circulating fluidized bed combustor (CFBC) has been regarded as a viable alternative to the conventional pulverized coal combustor (PCC) for utility-scale coal power generation owing to its superior technology for fuel flexibility and supercritical (SC)/ultra supercritical (USC) steam circuit adaptability. The objective of this study is to analyze the economic feasibility of a 600MWe USC CFB boiler, in which coal or a mixture of coal and biomass would be used as fuel. After the demonstration and commercialization of SC CFBC units had succeeded up to 600MWe, USC CFBCs have been widely developed throughout the world. Although high capital costs, high auxiliary power use, and technology maturity have hindered the adoption of USC CFBC for utility power generation, the demand of cleaner environments and energy conversion have driven communities to develop and adopt USC CFBC. Its economic feasibility was evaluated in terms of net present value (NPV), benefit/cost ratio (B/C ratio), and internal rate of return (IRR). In particular, the effect of coal tax and domestic biomass co-combustion on economic efficiency was analyzed.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The economic feasibility of 600MWe USC CFB power plant were investigated. </LI> <LI> The economic efficiency of biomass co-combustion could be higher than that of coal combustion due to carbon trade exchange. </LI> <LI> The 600MWe USC CFB power plant with biomass co-combustion could be feasible in spite of coal tax or carbon tax. </LI> </UL> </P>
