The objective of the present study is to induct the regression equation for the hardness prediction of cellulose acetate filter which was manufactured by the domestic cellulose acetate tow manufacturer. As a result of our study, the hardness of filter was increased with increasing the plasticizer content and packing density as major factors affecting to the filter hardness. As a result which was obtained by the three dimensional response surface methodology in STATISTIC A program, the hardness prediction value well fitted with experiment result on the high plasticizer content. To make up for the this equation, the new modified fraction of solid factors which was contained the mono denier factor was introduced to the hardness prediction equation, and this third regression equation which was sufficient for the wide plasticizer content, was obtained by the three dimensional response surface methodology in STATISTICA. This results indicated that the third regression equation which was obtained this study was applicable for the hardness prediction of cellulose acetate filter which was manufactured by the domestic cellulose acetate tow manufacturer.

1. The purpose To know the characteristics of Sasang Constitutional Medicine treatment for cronic rhinitis patients. 2. The method We analyzed statistically 104 patients who had consulted for cronic rhinitis in Iksan Wonkwang Oriental Medicine for three years from 1999 to 2001, using electronic chart developed by Kim Jong-Yeol. 3. The results 1) The efficiency rate of treatment was 73.8% and the recurrence rate was 51.1 %. the recurrence period was within 6 months in 76.0%, so we could consider the group not recurred within 6 months as successfully treated. 2) The number of Taeumin was 64.4% of total patients, which was higher than the rate of Taeumin to all patients during same period in Iksan Wonkwang Oriental Medicine. 3) The sufficiency rate of treatment was high when the treatment period was 30-60 days. 4) The prescriptions especially efficient for treatment were those treating exterior syndrom of each constitution.

Objectives : To evaluate the properness and effectiveness of the question categories concerning 'total physiognomy', used in Iksan Wonkwang Oriental Medicine. Methods: We statistically analyzed data from those 1335 patients focussing on 'relative discrimination ability' to sasang constructions and 'response ratio'. Patients included in this research are only those who had been well treated in Iksan Wonkwang Oriental Medicine during the Period of three years from 2000 to 2002. The data are obtained through the electronic chart developed by Kim Jong-Yeol, and analyzed using the statistical Package SPSS. Results: The first category for discriminating Taeum type, 'heavy and looking steady', has more discriminating power and effectiveness among women than men, and especially in wemen with an age of 21 or more. The second category for discriminating Soeum type, 'delicate and modest', is more discriminating and effective among men than women, and mostly among men with ages 21-40. The third category for Soyang type, 'fast and brave', is almost equally discriminating and effective to both women and men, especially among women with ages 40 or less and among men with ages 21 or more. Finally, the forth category for discriminating Taeyang type, 'progressive', is neither discriminating nor effective among most the women than men in all age groups. Conclusions: The definition of 'relative discriminating power of constitution' and 'response ratio' are well evaluating the properness and effectiveness of the question categories regarding 'total physiognomy'. The first category is most discriminating and effective among women with ages 20 or less, and the second among 21-40 year old men, the third among women with ages 40 or less and among men with ages 21 or over. The forth category is neither discriminating nor effective.

본 논문에서는 KrF 레이저를 이용한 격자 공정 후 고온 어닐링 온도조건에 따른 감마방사선 영향을 분석하였다. 제작된 광섬유 브래그 격자는 게르마늄(Ge)이 첨가된 동일한 광섬유에 어닐링 온도를 달리하여 제작하였으며, $Co^{60}$ 감마선원을 이용하여 약 115 Gy/min의 선량률로 총선량 약 31 kGy 감마선을 조사하였다. 격자의 안정화를 위한 고온 어닐링 공정은 광섬유 브래그 격자의 방사선 민감도 변화에 영향을 주는 것으로 나타났다. 실험결과를 통하여, 각각 다른 온도(100, 150, $200^{\circ}C$)로 안정화시킨 광섬유 브래그 격자들은 고온에 노출될수록 방사선 민감도가 증가했으며, 어닐링 온도조건에 따라서 방사선에 의한 브래그 파장 변화는 2배 이상의 차이를 보였다. In this study, we studied the gamma-radiation effect of fiber Bragg gratings (FBGs) on the high temperature annealing condition after grating inscription using a KrF UV laser (248 nm). The FBGs were fabricated in a different annealing temperature using the same commercial Ge-doped silica core fiber (SMF-28e) and exposed to gamma-radiation up to a dose of 31 kGy at the dose rate of 115 Gy/min. The high temperature annealing procedure for grating stabilization was applied to change the radiation sensitivity of the FBGs. According to the experimental data and analysis results, the gratings that were stabilized at different temperatures at 100, 150 and $200^{\circ}C$ have clearly shown that exposure to higher temperatures increases their radiation sensitivity. The radiation-induced Bragg wavelength shift (BWS) was shown a difference of up to about a factor of two depending on the annealing temperature conditions of the gratings.

본 논문에서는 격자 공정 중에 KrF 엑시머 UV 레이저 노출시간에 따른 광섬유 브래그 격자의 $Co^{60}$ 감마방사선 영향을 연구하였다. 광섬유 브래그 격자는 게르마늄이 첨가된 일반 광섬유를 이용하였으며, UV KrF 엑시머 레이저 노출시간(30, 60, 90, 120초)을 달리하여 제작하였다. 제작된 광섬유 브래그 격자에 106 Gy/min 선량률로 총 선량 34.3 kGy 감마선을 조사한 후 방사선에 의한 온도감도 계수와 브래그 파장 변화를 분석하였다. 실험결과를 통하여, 격자 공정을 위한 UV 레이저 노출시간이 광섬유 브래그 격자의 방사선 민감도에 큰 영향을 줄 수 있다는 것을 확인하였다. 레이저 노출조건 변화에 따른 방사선에 의한 광섬유 브래그 파장의 변화는 최대 50 % 이상의 차이를 보였다. We studied the effect of $Co^{60}$ gamma-radiation on the fiber Bragg gratings (FBGs) by irradiation time of UV Krypton fluoride (KrF) excimer laser among grating processing parameters. The FBGs were fabricated in a different UV laser irradiation time at 30, 60, 90, and 120 seconds using the same commercial Ge-doped silica core fiber (SMF-28e). It was exposed to gamma-radiation up to a high dose of 34.3 kGy at the dose rate of 106 Gy/min, and then it was analyzed radiation effects by measuring the radiation-induced change in the temperature sensitivity coefficient and Bragg wavelength shift. According to the experimental results, We confirmed that the UV laser irradiation period for grating inscription has a highly effect on the radiation sensitivity of the FBGs. The radiation-induced Bragg wavelength shift by the change of laser irradiation conditions showed a difference more than about 50 %.
