To study the effect of moisture content of the diet on drinking behaviour and the amount of water drunk, observations were made on 8 Holstein steers fed either fresh cut forage or first cut hay. The observations were made in a barn with a mean temperature of about $13^{\circ}C$. Drinking occurred mainly within 3 hours after feeding for the steers fed hay, while those fed soilage drank casually. Frequency of drinking (F) was related to the dry-matter concentration (DMC, %) of herbage: F = 0.47 (${\pm}0.09$) DMC - 6.5, $SE={\pm}0.4$, r = 0.86, P<0.01. Intake of drinking water for each 100 kg of live weight (IDW/100kg) for steers fed soilage was related to the dry-matter concentration: IDW/100kg = 0.55 (${\pm}0.06$) DMC - 8.7, $SE={\pm}0.3$, r = 0.94, P<0.01. The intake of water in each drinking period for animals fed fresh forage was curvilinearly related to the drinking frequency; for the hay-fed steers there was a negative linear relationship. When the drinking frequency for steers fed the fresh forage increased to the same as that observed for the hay, water intake in each drinking period was the same as found for the hay-fed steers.

Acylation of an intermediate tetrahydroxoplatinum(IV) complex, $[Pt(OH)_4(dach)]$ (dach = $trans-(\pm)-12-di-aminocyclohexane)$, with one or two kinds of carboxylic anhydrides in stepwise manner afforded various car-boxylatoplatinum(IV) complexes, $[Pt(O_2CR)\chi(OR’)4-\chi(dach)]$ (R = $(CH_2)_3CH_3$ or $C(CH_3)_3$, R’ = H or $OCCH_3$, and $\chi$ = 1-4) with a wide range of lipophilicity. The title complexes were subjected to bioassay using the murine leukemia L1210 cell line, and in particular, their in vivo oral antitumor activity was attempted to correlate with their lipophilicity and water solubility. The most orally active complex exhibited intermediate lipophilicity and water solubility, but it has been found that an exact relationship between the lipophilicity and oral anticancer activity could not be established, since the lipophilicity of the complexes is not the sole parameter to determine the oral activity. One of the important intermediate complexes partially substituted was subjected to X-ray anal-ysis for positit of the substituted group: $[Pt(OPiv)_3(OH)(dach)]$ crystallizes in the tetragonal sys-tem, space group $P42_1c$ with a = 21.161(3) $\AA$, b = 21.161(6) $\AA$, c = 12.816(3) $\AA$, $\alpha=\beta=$ r $=90^{\circ}$, V = 5739(2) $\AA^3$ and Z = 8.

The properties of bright galaxies are closely related to those neighbors and satellite galaxies. However, the effects of nearby companion are known to be very weak in a galaxy cluster, when the companions are bright galaxies. On the other hand, until now, it has not been clear whether the properties of bright galaxies are affected by their faint satellites in a galaxy cluster. Recently, J. H. Lee et al. (in preparation) have found that the colors of bright galaxies in WHL J085910.0+294957, a galaxy cluster at z = 0.3, show a measurable correlation with the mean colors of faint galaxies around them. To confirm that result and to investigate the host-satellite relationship depending on cluster properties, we carry out follow-up studies of a few galaxy clusters, beginning with Abell 3659 (z ~ 0.0907) imaged in the g' and r' bands using IMACS on the Magellan (Baade) 6.5m telescope. Cluster members are selected based on the distributions of color, size and concentration along magnitude and spatial distribution. In this poster, we present some preliminary results: marginal correlations in color between bright galaxies and their faint companions are found at the central region of Abell 3659. The implication of these results is discussed.

To investigate weathering and surface characteristics of coating film on lumbers coated with Hwangchil(varnish of Dendropanax morbifera), we carried out to investigate the resistance against discoloration, value of crack and surface characteristics of coating films on seven domestic lumbers and those of four introduced tropical lumbers. There was investigated to evaluate the properties of coating films by the varnish of Dendropanax morbifera. There was insignificant correlations between the hardness and moisture contents of each lumber treated by the varnish. There was no significant correlations between the thickness of coating film and the hardness, either. Although we investigated 11 wood species, we found only three species as resistance wood species against discoloration; Diospysos spp., Abies holophylla and Ulmus davidiana. The crack of coaing films was the largest on Zelkova serrata followed by Juglans sinensis, Cercidiphum japonicum, Tectona grands, Ulmus davidiana, Guibourtia tessmannii, Diospysos spp. and Dalbergia latifolia. However, there was no crack of coating films on the lumbers of Juniperus rigida, Prunus serrulata var. spontanea and Abies holophylla. The crack of coating film showed positive correlations with the thickness of coating film and hardness. The surface characteristics of the coating films evaluated on the basis of $R_{a}$ values indicated the lumbers of Ulmus davidiana($0.14{\;}{\mu}m$), Juniperus rigida($0.1 5{\;}{\mu}m$), Guibourtia tessmannii($0.19{\;}{\mu}m$), Dalvergia latifolia($0.20{\;}{\mu}m$) and Diospysos spp.($0.20{\;}{\mu}m$), Cercidiphum japonicum($0.24{\;}{\mu}m$) as good species while there was insignificant differences between softwoods and hardwoods. Tectona grands, Prunus serrulata var. spontanea and Abies holophylla showed rough surface with $1.53~2.63{\;}{\mu}m$ of $R_a$ values. The four kinds of rough indices($R_a,{\;}R_z,{\;}R_{max}{\;}and{\;}R_q$) showed very low correlations with moisture contents with the correlation coefficients. The $R_a{\;}and{\;}R_{max}$ also showed slight relationship with hardness.

Purpose: The purpose of this study was to assess the relationship between cognitive function impairment and quality of life (QoL) among patients with breast cancer. Specifically, the intention was to verify the mediating effects for promoting behaviors leading to better health and QoL. Methods: A purposive sample of 152 patients undergoing chemotherapy was recruited. A cross-sectional survey design was used. Data were collected using four instruments: Everyday Cognition Scale, Korean Mini-Mental State Examination, Functional Assessment of Cancer Therapy-Breast Cancer Version 4, and Health Promoting Lifestyle Profile. Results: The mean score for subjective cognitive decline was 65.84; the health promotion behavior was 95.89, and 83.34 for QoL. Health promotion behavior was directly affected by cognitive decline ($R^2=6.0%$) as was QoL ($R^2=43%$). Subjective cognitive decline (${\beta}=-.57$ p<.001) and health promotion behavior (${\beta}=.37$, p<.001) were seen as predicting factors in QoL and explained 56% ($R^2=56%$). Health promotion behavior had a partial mediating effect in the relationship between self-reported cognitive decline and QoL (Sobel test: Z=-3.37, p<.001). Conclusion: Based on the findings of this study, nursing intervention programs focusing on managing cognitive decline and promoting health promotion behavior are highly recommended to improve QoL in cancer patients.

Purpose: This study aims to investigate the mediating effect of grit in the relationship between body image and health promotion lifestyle for nursing students. It was implemented to present basic data for the development of educational programs to establish the health promotion lifestyle of nursing students. Methods: The participants of this study were 169 nursing students in three universities in G City, J Province. Data were descriptive statistics, t-test, ANOVA, Pearson correlation analysis. Also mediation analysis was performed according to the Baron and Kenny method and Sobel test. Results: Health promotion lifestyle is positively correlated with body image(r=.53, p<.001), grit (r=.37, p<.001), and body image is positively correlated with grit(r=.33, p<.001). The grit showed a partial mediating effect between the body image and the health promotion lifestyle(Z=3.21, p<.001), the positive the body image(β=.46, p<.001), the higher the grit(β=.22, p<.001), the healthier the health. The level of health promotion lifestyle increased, and the explanatory power to explain the health promotion lifestyle was 33%. Conclusion: Therefore, in order to improve the health promoting lifestyle level of nursing students, it is important to change their perception so that they can view their body image positively. In addition, it suggests that nursing students need to cultivate grit so that they can continuously pay attention to and strive for their health promotion lifestyle.

Purpose: This study explored the mediating role of resilience between post-traumatic stress and emotional exhaustion in nurses during the COVID-19 pandemic. Methods: The data were collected from 193 nurses working at a hospital in Daegu from October 16 to 30, 2020, in the middle of the COVID-19 pandemic. Participants conducted self-reported surveys of post-traumatic stress (Impact of Event Scale-Revised Korean version), emotional exhaustion (Maslach Burnout Inventory), and resilience (Korean Resilience Quotient Test). The data were analyzed using descriptive statistics, frequency, t-tests, Mann-Whitney U tests, Kruskal-Wallis tests, Pearson correlation coefficients, and multiple regression. Mediation analysis was performed using the Baron and Kenny method and Sobel test. Results: The mean scores for post-traumatic stress, resilience, and emotional exhaustion were 16.18±16.18, 183.41±18.29, and 32.64±9.66, respectively. A higher level of post-traumatic stress was associated with lower resilience (r=-.20, p=.004) and with higher emotional exhaustion (r=.33, p<.001). A higher level of resilience was associated with lower emotional exhaustion (r=-.35, p<.001). The resilience was confirmed to have a partial mediating effect in the relationship between post-traumatic stress and emotional exhaustion, verified by the Sobel test (Z=2.31, p=.02). Conclusion: Resilience had a partial mediating effect in the relationship between post-traumatic stress and emotional exhaustion. Thus, nurses should develop individual strengths to reduce emotional exhaustion, and managers should also make efforts to increase the nurses' resilience. It is also necessary to develop and apply a program to strengthen nurses' resilience.

본 연구는 화력발전소 배출로 인한 지표면 오염물질 농도의 시·공간적 영향을 실측 자료를 바탕으로 정량적으로 분석하려는 목적으로 수행되었다. 배출과 농도 관계의 정량적 분석을 위해 우선 기상 조건과 주변 배출원의 영향을 고려하였다. 이를 위해 자료의 선택과 관측지점 선정 과정을 제안하였고, 선정된 지표면 시·공간 자료에 K-Z 필터와 경험직교함수(EOF) 분석 기법을 적용하였다. 사용된 자료는 2014-2017년 4년의 기간 동안 당진과 태안 화력발전소 굴뚝 자동측정기기의 농도값을 이용하여 산출한 한 시간 평균 배출량 자료와 지표면 대기오염농도 측정망 자료이다. 기상 자료로는 최근 배포 중인 ERA5 재분석자료와 기상청 종관기상관측소 한 시간 평균 자료가 사용되었다. 발전소만의 영향이 최대한 보이도록 기상 효과와 지리적인 요인을 고려하여 선택한 시간대의 선정된 관측소 자료만을 이용하여 분석한 결과, 지표면 대기오염물질의 EOF 첫 번째 모드는 SO₂, NO₂, PM₁₀ 모두에 대해 97% 이상의 변동성을 설명하였다. 또한 지표면 농도장의 EOF 첫 번째 모드의 시계열은 화력발전소 배출과 유의미한 상관성을 보였다. 결과적으로 당진화력발전소 SO₂, NO₂, TSP 시간 당 배출량이 각각 10%가 감소하면, 남서풍 계열의 바람에 의해 직접 영향을 받는 서울 수도권 지표면 평균 SO₂ 농도는 0.468 ppb (R=0.384), NO₂는 1.050 ppb (R=0.572), PM₁₀은 2.045 ㎍ m^-3 (R=0.343) 정도가 감소한다고 판단할 수 있다. 태안화력발전소의 경우, SO₂, NO₂, TSP 배출량을 각각 시간당 10% 씩 감축하면, SO₂는 0.284 ppb (R=0.648), NO₂는 0.842 ppb (R=0.683), PM₁₀은 1.230 ㎍ m^-3 (R=0.575) 정도가 감소될 수 있음을 확인하였다. 태안화력발전소는 당진화력발전소에 비해 수도권지역 농도에 미치는 영향은 작았으나, 상관관계는 더 높았다.
