The main purpose of this study is to examine the effect of patient-centered communication of doctor(facilitating factor, inhibition factor) on patient participation(behavioral participation, emotional participation, informational participation). Concretely, it is confirmed where there are effects of patient-centered communication of doctor to patient participation and whether there are moderating effects of trust between patient-centered communication of doctor and patient participation. In domestic general hospital, 301 samples were for this analysis collected and tested by factor analysis and moderating regression analysis. As a result of this study is as followings. First, it is confirmed that communication facilitating factor have influences on patient participation positively and communication inhibition factor have no influences on patient participation. Second, there are moderating effects of trust between facilitating factor and emotional participation, between facilitating factor and informational participation. Especially, in higher level group of trust, it is confirmed that facilitating factor more influence on emotional participation and informational participation. On the basis of these study results, I suggested theoretical and practical implication for the patient-centered communication and successful medical service.

We were investigated turf color and Normalized Difference Vegetation Index (NDVI) to affect greenup promotion of 38 cultivar in 5 species for spring season, most popularly used in Korea golf courses. Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb), creeping bentrgass (Agrostis palustris Huds), perennial ryegrass (Lolium parenne L.) and zoysiagrass (Zoysia spp.) cultivar had higher leaf color for greenup promotion in Ami, Amx and Oligo than Con treatment and there were also significantly difference among treatments. Turfgrass NDVI also showed significant difference among cultivars in species. Spray of Ami, Amx and Oligo has the higher value of turf NDVI than Con. Based on our results, green up fast during spring season may affected much more with application of Ami, Amx and Oligo than Con.

The effect of Group I alkali acetate promoters on vinyl acetate (VA) synthesis was evaluated. Catalyst product selectivity and ethylene conversion are compared to the unpromoted catalyst in the fixed-bed reactor with oxidation reaction of ethylene and acetic acid in gaseous phase over Pd-Au/$SiO_2$ catalyst. It was found that: a) the promoters were stabilized on the catalyst surface, b) common effect for the alkali promoted Pd-Au catalysts increaseed in product selectivity and ethylene conversion compared to unpromoted catalyst (these effects increase from top to the bottom of Group I). These promoting effect is due to the common-ion effect of acetate, present in the reaction, resulting in an increase in the activity of the catalyst. In addition a complementary theory for the effect of Au in the structure of the catalyst is proposed the imposition of distribution of palladium particles through decreasing the particle's diameter.

Dredging and reclamation which have been conducted steadily for creation of new coastal area have the demerit of taking a long time. Hence, a lot of researches on acceleration of self-weight consolidation have been proceeding continuously. In this paper, 30 cases of laboratory self-weight consolidation tests were conducted to understand the application of PDF method, one of the self-weight consolidation acceleration methods, to domestic dredged soils. Acceleration effect of self-weight consolidation was confirmed through comparison and analysis of completion times and settlements of self-weight consolidation for none installed case and 4 kinds of common used PBD installed cases. As a result of the tests, installation of PBD before filling is effective for time reduction of self-weight consolidation.

To investigate the stimulating effects of the low- dose radiation, the seeds of chinese cabbages (Brassica campestris L. cv. Hanyoreum and cv. Tropic emperor) were irradiated at the dose of 0.5 Gy~20 Gy with the ${\gamma}$-ray radition. In case of ‘Hanyoreum’cultivar, there were no significant promoting effects on the germination rate except the 0.5 Gy irradiated group. The increase in seedling height and fresh weight in 8 Gy and 12 Gy irradiated groups was 20% and 40%, respectively, which suggested the stimulating effect of the low-dose radiation on the early growth. In case of‘Tropic emperor’cultivar, the germination rate of 1 Gy irradiated group increased approximately 10% and the seedling height and fresh weight of 1 Gy and 12 Gy irradiated group in the greenhouse 20% on the average, and plant height and fresh weight of 0.5 Gy and 4 Gy irradiated group in the field increased 10% and 20% on the average, respectively.

신장 근위세뇨관세포들은 사구체에서 여과된 물질의 재흡수, 분비 및 대사에 관여하는 여러 호르몬들의 수용체들을 가지고 있다. 이들중에서 dopamine(DA)과 angiotensin II(ANG II)가 $Na^{+}/H^{+}$ 상호운반계 조절에 중요한 역할을 하고 있다. 본 연구는 초대배양한 토끼 신장 근위세뇨관세포의 $Na^+$ uptake에 있어서 DA과 ANG II의 상호관계를 알아보고자 실시하였다. DA은 농도의존적으로 $Na^+$ uptake를 유의성 있게 억제하였다($10^{-6}M$ ; $83.2{\pm}7.2%$, $10^{-3}M$ ; $67.2{\pm}3.8%$ vs. control)(p<0.05). $DA_1$ 작동제(SKF 38393, $10^{-6}M$)는 대조군의 $81.4{\pm}6.7%$ 까지 $Na^+$ uptake를 유의성 있게 억제하였으나(p < 0.05) $DA_2$ 작동제는 영향을 미치지 않았다. $DA_1$ 길항제(SCH 23390, $10^{-6}M$)에 의해 DA의 $Na^+$ uptake 억제효과는 차단되었으나 $DA_2$ 길항제(spiperone, $10^{-6}M$)에 의해서는 영향을 받지 않았다. DA과 대조적으로 $10^{-11}M$ ANG II는 $AT_1$ 수용체를 통하여 대조군의 $120.7{\pm}4.9%$까지 $Na^+$ uptake를 유의성 있게 촉진하였다. (p < 0.05). DA 및 $10^{-11}M$ ANG II를 병합처리하였을 때 DA은 농도의존적으로 ANG II에 유도된 $Na^+$ uptake 촉진효과를 유의성 있게 차단하였다(p<0.05). 한편 ANG II에 의해 유도된 $Na^+$ uptake촉진작용은 $DA_1$ 또는 $DA_2$ 작동제에 의해 차단되었으나 DA에 의한 차단 효과는 $DA_1$ 및 $DA_2$ 길항제를 병합처리하였을 때만 반전되었다. 결론적으로 DA은 $DA_1$ 수용체를 통하여 $Na^+$ uptake를 억제하였으나 ANG II에 의한 $Na^+$ uptake 촉진작용의 억제에는 $DA_1$ 및 $DA_2$ 수용체 모두가 관여하였다.

This study examines the effects of the "youth unemployment bonus" program implemented in 2004. We view this program through the lenz of search-matching models and apply a quasi-experimental approach to an administrative unemployment insurance database of Korea. This episode is particularly useful because the program aims at long-term unemployed youths and the size of public assistance is large enough to subsidize employers for a year with a monthly subsidy of about $600. The main effects are found to be as follows: (i) the search period gets shortened by 18 days, (ii) the subsequent wage has increased by about three percents, and (iii) a conservative benefit-cost analysis reveals the validity of this program. We interpret these results in the context of general equilibrium models.

In the present study, we investigated the effects of Rubus coreanus Miquel (RCM) on memory ability of senescence-accelerated mice (SAM). Prone 8 strains of SAM mice (SAMP8), which is a useful animal for investigating the mechanism of brain aging and senile dementia, were fed a diet containing 100 mg/kg body weight/day of RCM for 8 weeks. Memory ability of mice was examined by using passive avoidance test and Morris water maze test. SAMP8 mice showed remarkable memory impairment compared with senescence-resistant 1 strains of SAM (SAMR1). RCM significantly improved memory ability of SAMP8 mice. In addition, acetylcholineasterase activities decreased in the brain of SAMP8 mice treated with RCM. Taken together, these results suggest that RCM may act as an acetylcholineasterase inhibitor, thereby improving senescence-related memory impairment.

본 연구에서는 알콜계 물질인 1-propanol과 2-propanol이 가스 하이드레이트 형성과정에서 격자내로 포집됨과 열역학적 촉진제로서 작용함을 알아보기 위해 $CH_4$ (또는 $CO_2$) + 1-propanol (또는 2-propanol) + 물계의 가스 하이드레이트 3상 평형 (하이드레이트(H) - 물(Lw) - 기상(V))을 측정하였으며, $^{13}C$ NMR 분석을 하였다. 1.0, 5.6, 10 mol%의 농도 1-propanol (또는 2-propanol) 용액을 가스 하이드레이트 계에 첨가하여 3상 평형을 측정한 결과, $CH_4$ 하이드레이트의 경우 전반적으로 촉진현상을 보였으며 5.6 mol%에서 가장 큰 촉진효과가 나타났다. 하지만 $CO_2$ 하이드레이트의 경우 순수 $CO_2$ 하이드레이트에 비해 저해효과가 나타났으며 농도가 높아질수록 저해현상은 커짐을 확인할 수 있었다. $^{13}C$ NMR을 통한 동공점유 특성과 하이드레이트 구조 분석 결과 $CH_4$ + 1-propanol (또는 2-propanol)은 구조-II를 형성하며 1-propanol (또는 2-propanol)이 동공에 포집되어 있음을 확인할 수 있었다. 이상의 결과로부터 알콜계 물질이 단순히 저해제로만 작용하지 않고 가스 하이드레이트 형성에 참여하는 촉진제로 작용할 수 있다는 사실을 알 수 있었다.
