Purpose: The purpose of this study was to identify the effects of CD-ROM education on anxiety and self-care compliance in patients undergoing spinal surgery. Method: This study used a nonequivalent control time difference design. A sample of 51 participants received both CD-ROM education (n=25) or booklet education (n=26) regarding spinal surgery procedure and postoperative self-care. The data were collected using a self-administered questionnaire containing State-Trait Anxiety Inventory (STAI Form Y-2), Visual analog scale, and self-care compliance. Result: The level of trait anxiety in the experimental group was not significantly different from that in the control group (t=-6.44, p=.523). The level of state anxiety in the experimental group was significantly lower than in that the control group according to time changes (F=4.17, p=.018). State anxiety showed significantly negative correlation to self-care compliance (r=-.30, p=.034). Conclusion: The education program using CD-ROM for spinal surgery patients can be applied to nursing practice for relieving state anxiety and promoting self-care compliance.

무기안료는 우수한 열적, 화학적 안정성으로 인해 페인트, 고화도 세라믹 잉크, 아트 타일, 건물의 외장재 등의 다양한 응용 분야에 적용될 수 있어 큰 관심을 받고 있다. 기존에는 $PbCrO_4$, CdS, CdSe 등의 조성이 노란색 무기 안료로 널리 사용되어 왔으나 Cd, Cr, Pb, Se 같은 유해물질을 포함하고 있어 최근에는 사용에 제한되고 있다. 따라서 본 연구에서는 ceria 기반의 조성을 이용하여 고상법으로 친환경 노란색 무기안료를 합성하였다. XRD와 SEM을 통해 합성된 $Ce_{1-x}Zr_xBi_yO_{2-y/2}$ 노란색 무기안료의 결정구조와 형상을 확인하였고, UV-vis. spectrophotometer와 CIE $L^*a^*b^*$ 분석으로 Zr과 Bi함량에 따른 노란색 무기안료의 발색 특성 변화를 확인하였다. 노란색 무기안료의 결정구조는 주로 하소온도의 변화에 의존하는 것으로 확인되었고, 발색 특성과 흡수단은 하소온도와 Zr, Bi 함량이 모두 영향을 미치는 것으로 나타났다. 결과적으로 합성된 모든 무기안료는 자외선과 500 nm 이하의 가시광선을 효율적으로 흡수하였고, $Ce_{0.44}Zr_{0.36}Bi_{0.20}O_{0.19}$(x = 0.36, y = 0.20) 조성의 무기안료에서 가장 선명한 노란색 색조를 확인할 수 있었다.

This study was carried out to investigate the inhibitory effect of Angelicae Dahuricae Radix (ADR) extract on chronic obstructive pulmonary disease (COPD) induced by cigarette smoke condensate (CSC) and lipopolysaccharide (LPS) in mice. COPD was induced by intratracheal instillation of LPS and CSC 5 times for 12 days; this increased airway hyperresoponsiveness (AHR) and inflammatory cells in bronchoalveolar lavage fluid (BALF). ADR extract was administered orally at a dose of 50 and 200 mg/kg. The concentration of imperatorin, a major component of ADR and therefore used as a measure of quality control, was $0.098%{\pm}0.018%$. Treatment of the mice with ADR extract (50 and 200 mg/kg) alleviated AHR and reduced inflammatory cell counts. Treatment with cyclosporin A (CSA; 10 mg/kg) also modulated AHR and reduced inflammatory cells effectively. Compared with CSA treatment, treatment with ADR (50 mg/kg) extract reduced neutrophil and $CD4^+/CD3^+$ cell counts by 22.67% and 44.92%, respectively. In addition, compared with CSA treatment, treatment ADR 200 mg/kg reduced neutrophils, $CD4^+/CD3^+$ cells and $CD8^+/CD3^+$ cells, by 32.10%, 83.17% and 82.11%, respectively. These results indicate that ADR extract may have an inhibitory effect on COPD induced by LPS and CSC in mice.

This study was carried out to investigate the amounts of voluntary intake, digestibility and nitrogen retention in Korean native goats (KNG) fed agricultural by-products containing rice straw (RS) and apple pomace (AP) and to obtain a basic information for establishing the feeding system of KNG. The result are as follows. 1. Among the chemical composition of experimental diets, the highest values in crude protein (CP ; 18.6%) and crude ash contents (10.7%) were observed in alfalfa hay. Those of RS+AP treatment were significantly low 6.0 and 4.8%, respecitively. Acid detergent fiber (ADF), ether extract and non-structural carbohydrate (NSC) contents were shown an adverse tendency. 2. Dry matter (DM) intakes per day in KNG fed RS+commercial diet (CD), RS+AP and RS+AP+CD were significantly lower (P<0.05) 210.3, 228.3, respectively than 358.1g in alfalfa hay. 3. DM intakes per basal weight expressed as DM g/kg of BW0.75 and DM g/kg of BW(%) were highest (P<0.05) 60.5g and 3.3%, respectively in KNG fed alfalfa hay, any other treatments showed 35.6 to 42.5g and 2.0 to 2.3%, respectively and this result was similar to those of DM intake per day. 4. Digestibilities of DM, organic matter, CP, ADF, neutral detergent fiber (NDF). crude ash and ether extract in alfalfa hay and RS+AP+CD treatment were significantly higher (P<0.05) than RS+CD treatment. Those of CP, ADF and NDF of RS+AP treatment in not significantly different with these treatments. 5. NSC digestibility was higher in alfalfa hay (66.7%) than those of other treatments (44.2~52.0% ; P<0.05). 6. Nitrogen retentions expressed as N retention(g) and N retention (%) in KNG were highest (P<0.05) 0.6g and 15.6%, respectively in RS+AP+CD treatment and RS+CD treatment was lowest (P<0.05) -06g and -21.4%, respectively.
