스칼라 곱셈은 정수 $textsc{k}$와 타원곡선 상의 한 점 P가 주어졌을 때 $textsc{k}$P를 계산하는 연산이다. 스칼라 곱셈을 빠르게 하기 위한 일반적인 방법으로 Agnew Mullin, Vanstone은 고정된 값의 해밍 웨이트를 갖는 스칼라 $textsc{k}$를 이용하는 방법을 제안하였다. 본 논문에서는 고정된 값의 부호화 해밍 웨이트를 갖는 $textsc{k}$를 이용하는 방법을 제안하고, 이 방법이 더 안전함을 보인다.

유전자변형 장미 개발에 이용된 형질전환 벡터 pSPB130을 검출할 있는 duplex PCR이 개발되었다. 유전자변형 장미를 검출하기 위해 anthocyanin synthase($ANS$)가 장미 내 재유전자로 PCR 검사법에 이용하였다. 107bp의 PCR 산물을 얻을 수 있는 RHANS-KF/KR primer가 ANS 유전자를 증폭시키는데 이용되었고, 이것을 이용하여 9개의 다른 식물에 대해서 PCR한 결과 장미에서만 특이적인 증폭산물이 확인되었다. GMRH-KF/KR primer가 형질전환 벡터 pSPB130에 삽입된 35S promoter와 flavonoid 3',5'-hydroxylase($F3^{\prime}5^{\prime}H$) 사이의 염기서열을 확인할 수 있도록 제작되었다. 본 연구에서 개발된 duplex PCR의 검정한계치는 약 0.5%이며, 이러한 duplex PCR이 우리나라 미승인 유전자변형 장미를 모니터링 하는데 유용하게 사용될 수 있을 것이다.

When certain general single or multiple hypergeometric functions were introduced, their reduction formulas have naturally been investigated. Here, in this paper, we aim at presenting a very interesting reduction formula for the Srivastava's triple hypergeometric function $F^{(3)}[x,y,z]$ by applying the so-called Beta integral method to the Henrici's triple product formula for hypergeometric series.

Purpose: This study was conducted to verify the effects of an education program of restraints use on nurses' knowledge, attitude and nursing performance related to restraints use. Method: A quasi experimental study with a pre and post non-equivalent design was used. The subjects were nurses who met the selection criteria and worked in intensive care units of two university hospitals located at K-city, Gyeongbuk. Twenty nurses in A hospital were designated as the experimental group and 20 nurses in B hospital as the control group. Result: The first hypothesis which assumed that the experimental group would have higher scores of knowledge than the control group was supported(F=62.66, p=0.000). The second hypothesis which assumed that the experimental group would have lower scores of attitude toward using restraints than the control group was supported(F=23.77, p=0.000). The third hypothesis which assumed that the experimental group would have higher scores of nursing performance than the control group was supported(F=3.28, p=0.032). Conclusion: An education program for nurses' on the use of restraints needs to be introduced to decrease inappropriate use of restraints.

The purpose of this study was to evaluate the abrasion-resistance of root surface after NaF iontophoresis, Nd:YAG laser irradiation and combined treatment 50 anterior teeth with flat interproximal root surface that had been extracted due to periodontal destruction were selected. All teeth were treated by the same procedure as conventional periodontal root treatment, such as scaling and root planing, root conditioning with tetracycline HCI(lOOmg/ml, 5min). The pre-treatment weight of each tooth was measured by a dial scale(SHIMADEU Co, LIBROR EB-220HU, capacity 220.000 g, Japan). All teeth were divided into 5 groups as follows: Nd:YAG laser irradiation(group 1, 1 W, 100 mJ, 10Hz, fiberoptic-root surface distance=5mm, $10\;sec.{\times}6times$, EL.EN.EN060, Italy): NaF iontophoresis(group 2, $150{\mu}A$, 4 min}: Nd:YAG laser irradiation following NaF iontophoresis(group 3): NaF iontophoresis following Nd:YAG laser irradiation(group 4): No treatment(control group). Electric toothbrushing (Oral-B, Brown Co, Germany) was conducted during 1 hour($lO\;min.{\times}6\;times$). Subsequently post-treatment weight was remeasured by the same method as pre-treatment weight measurement. The difference of abrasion rate among all groups was statistically analyzed by ANOVA(SAS program). Following results were obtained: 1. The abrasion rate was significantly lower in Nd:YAG laser irradiation group than NaF iontophoresis group(p < 0.001). 2. The abrasion rate was significantly lower in combined groups of Nd:YAG laser irradiation and NaF iontophoresis than either Nd:YAG laser irradiation group or NaF iontophoresis group(p < 0.001). 3. There was no significant difference in abrasion rate according to application order in the combined groups(p > 0.05). 4. The abrasion rate was significantly lower in all experimental groups than control group(p < 0.001). The results suggest that combined treatment of Nd:YAG laser irradiation and NaF iontophoresis on exposed root surface after periodontal therapy can enhance the abrasion-resistance of root surface and may inhibit the root caries development.

Wool has excellent properties, such as heat retention, absorbency, and elasticity, but it has a disadvantage in washability because the fabric will felt and shrink greatly. Felting causes the interlocking of the fiber surface scales with one another. Therefore, the studies on wool finishing have been focused on shrink proofing. Precedent researches on wool shrink proofing are mostly on eco-friendly method. using enzyme. The purpose of this study is to examine the effect of L-cysteine, EDTA in papain treatment of wool fabrics. The specific contents of study are as follows. Depending on pH, temperature, treatment time, enzyme concentration and L-cysteine, EDTA concentration, weight loss, tensile strength, whiteness, SEM were examined. Each papain treatment conditions depending on L-cysteine, EDTA were optimized from these properties. Papain had very low activation without activators. The optimum conditions of papain treatment were pH 7.5, temperature $75^{\circ}C$, time 30minutes(L-cysteine), 180minutes(EDTA) and papain concentration 5%(o.w.f.). In the use of papain 5%(o.w.f.), the activators optimum concentration was L-cysteine 2%(o.w.f.), EDTA 7%(o.w.f.)

Methyl hydro-peroxide의 methyl group과 O-H에 F를 치환 시킨 fluoromethyl fluoroperoxide($CH_nF_{3-n}OOF$)의 안정한 conformers와 isomers에 대하여 MP2/6-311G(d,p) 방법과 B3LYP/6-311++G(d,p) 방법으로 최적화 계산을 수행하였고 vibrational frequencies를 구하였다. $CH_3OOF$와 $CH_2FOOF$, $CHF_2OOF$, $CF_3OOF$ 분자 모두 가장 안정한 형태는 skew 구조로 나타났으며 $CH_3OOH$와 비교할 때 대단히 짧은 O-O 결합길이를 갖는다. Trans, cis conformers의 경우 skew 형태보다 8-12 kcal/mol 정도 높은 에너지를 갖으며 O-O 결합길이는 훨씬 길어진다. $CH_2FOOF$, $CHF_2OOF$, $CF_3OOF$ 분자들은 methyl group의 F에 의한 induction 효과로 짧은 C-O 결합길이를 갖고 O-F 결합길이는 길어지나 치환된 F 원자의 수에 따른 구조변화는 그리 크지 않다.
