안희경(Hee Kyung Ahn),하영원(Young Won Ha) 한국마케팅학회 2001 마케팅연구 Vol.16 No.1

본 연구에서는 첫째, 기업브랜드(corporate brand) 스테레오타입에 일치하지 않는 정보의 제시패턴에 따라서 스테레오타입의 변화가 어떻게 달라지는지를 살펴보고, 둘째, 기업브랜드 스테레오타입에 일치하지않는 정보의 제시패턴이 스테레오타입의 변화에 영향을 미치는데 있어서 기업브랜드의 시장지위와 기업브랜드 내 개별제품들간 적합성의 조절적 역할을 규명하여 이 변수들간의 상호작용을 검증하고자 하였다. 본 연구에서 발견한 것들을 요약하면, 첫째, 선행연구들에서 나타난 바와 같이 스테레오타입에 일치하지않는 정보를 단일의 제품에 집중하여 제시하는 경우보다 다수의 제품에 각각 분산하여 제시하는 경우가 기업브랜드 스테레오타입이 더 많이 변한다는 결과가 나타났다. 둘째, 우위기업브랜드의 경우에는 스테레오타입에 일치하지 않는 정보가 집중되어 있는 경우보다 분산되어 있는 경우에 기업브랜드 스테레오타입의 변화가 더 많이 일어났고, 열위 기업브랜드인 경우에는 스테레오타입에 일치하지 않는 정보의 제시패턴에 따른 유의한 차이가 나타나지 않았다. 셋째, 적합성이 높은 경우는 분산하여 제시할 때가 집중하여 제시할 때보다 더 많이 변했고, 적합성이 낮은 경우는 제시패턴에 따른 유의한 차이가 나타나지 않았다. 이 같은 결과가 갖는 이론적 및 실무적 시사점이 논의되었다. This research investigated (1) how stereotypic beliefs about corporate brands are influenced by the pattern of stereotype-incongruent information (concentrated vs. dispersed) and (2) how the market standing of the corporate brand and the fit among the products with the same corporate brand might moderate the corporate brand stereotype change. An experiment was conducted to examine these issues. The results show that the corporate brand`s stereotype change was greater when the stereotype-incongruent information was dispersed across several products with the same corporate brand than when it was concentrated in a single product. The corporate brand`s market standing played a moderating role in the corporate brand`s stereotype change. That is, there was a greater stereotype change for a topdog brand for the `dispersed` condition compared to the `concentrated` condition; but there was no statistically significant difference in the stereotypic belief change between the two conditions (concentrated vs. dispersed) for an underdog brand. There was statistically significant interaction effect between the pattern of incongruent attribute information and the fit among the products with the same corporate brand; the effect of pattern of stereotype-incongruent information emerged only when the fit was high. Theoretical as well as marketing implications of these results are discussed.

안희경(Hee Kyung An),박성직(Seong Jik Park) 大韓環境工學會 2014 대한환경공학회지 Vol.36 No.12

본 연구에서는 박테리아 제거를 위한 완속모래여과에서 탄소나노튜브(Carbon Nanotube, CNT)의 적용성을 검토하기 위해서 전자현미경 분석 및 칼럼 실험을 수행하였다. CNT의 형태적 특성을 분석하기 위하여, 주사전자현미경으로 분석한 결과 CNT는 박테리아 부착이 용이한 섬유형태로 응집되어 있었다. CNT의 충진 두께, pH, 이온강도를 달리하며 칼럼 실험을 수행하였다. CNT의 충진 두께가 1 cm, 3 cm, 5 cm로 증가할수록 박테리아 제거율이 44.15%에서 99.95%로 증가하는 것으로 나타났다. 반면, pH가 5.5에서 8.5로 증가할 경우 정전기적 반발력에 의해 박테리아 제거율이 감소하는 경향을 보였다. 이온강도를 0 mM에서 50 mM로 증가하여 칼럼 실험을 수행한 경우 박테리아 제거율이 97.25%에서 70.90%로 감소하였다. 본 연구를 통해 CNT가 오염된 물에 함유되어 있는 박테리아를 처리하는 완속모래여과에 적용 가능한 것으로 나타났다. The applicability of carbon nanotube (CNT) to slow sand filtration for the removal of bacteria was studied using scanning electron microscope and column experiments. The morphology of CNT were investigated using scanning electron microscope and the CNT looked like a skein serving bacteria favorable site for adhesion. Column experiments were performed over a range of CNT filter depth, pH, and ionic strength. Bacteria removal efficiency was found to increase from 44.15% to 99.95% as the CNT filter depth increased from 1 cm to 5 cm, and 3 cm of CNT filter depth was required for significant removal of bacteria. pH increase from 5.5 to 8.5 decreased the bacteria removal efficiency, due to the electrostatic repulsion between bacteria and CNT at higher pH. Bacteria removal efficiency decreased from 97.25% to 70.90% as the ionic strength increased from 0 mM to 50 mM. This study demonstrated that the CNT can be applied to slow sand filtration for treating microbially contaminated water.

본 연구에서는 소비자들이 숫자로 표현된 정보를 처리할 때 비율정보가 미치는 효과를 고찰하였다. 소비자들이 공공재를 소비하는데 있어서 비율에 더욱 초점을 두면서 소비하기 때문에 나타날 수 있는 현상을 실험실 상황에서 검증하였다. 세 개의 실험을 통해서 소비자들은 공공재를 소비함에 있어 절대양보다는 그 양이 전체에서 차지하는 비중이나 비율에 의해 소비 행동이나 절약하려는 의도에 영향을 받는다는 것을 알 수 있었다. 즉, 소비하려는 양의 비율이 전체에서 차지하는 정도가 크면 절대양이 같아도 적은 비율일 때보다 공공재를 소비하는데 있어서 절약을 덜 하려는 경향을 보인 것이다. 이를 바탕으로 공공 자원 절약을 유도하기 위한 정책이나 캠페인을 실행할 때, 효과적인 자원 절약을 유도하는 설득 메시지에 관련된 시사점을 이끌어 낼 수 있었다. The current research investigates the effects of numeric information (i.e., proportion information) on individual`s judgment and decision making, Based on the review of previous literature, we examine whether consumers` public resource saving behavior can be influenced by the differential numeric information processing In the domain of resource saving, we expect that individuals tend to focus more on proportion (vs. absolute amount) information of the resource they can consume immediately. As a result, this tendency seems to influence consumers` resource saving behavior. Across three laboratory experiments, we find that when the proportion of the total amount is low consumers` willingness to save the public resources is higher than when the proportion is high. We provide implications for conducting public policy campaigns and designing effective persuasin messages that can induce individuals` public resource saving prosocial behavior.

액상 비료를 유도 용액으로 사용하는 정삼투 기반의 해수 담수화

박성직,안희경,Park, Seong-Jik,An, Hee-Kyung 한국농공학회 2013 한국농공학회논문집 Vol.55 No.2

The present study explored the way to desalinate seawater for agricultural irrigation using forward osmosis (FO) process using liquid fertilizer as draw solution. FO experiments were performed in a cross flow mode using flat sheet FO membrane. The effect of membrane orientation, flow rate, and draw solution concentration on the performance of forward osmosis was investigated by measuring water flux of forward osmosis membrane. The water flux when the draw solution was placed against the membrane active layer was lower than the water flux when the feed solution was placed against the membrane active layer. This results indicated that the decrease of effective osmotic pressure by dilutive internal concentration polarization was less than that by concentrative internal concentration polarization. Increasing flow rate from 66.7 to 133.1 $cm^3$/min resulted in increase of the water flux when the membrane active layer orient to draw solution and feed solution, respectively. The reduction of resistance to water flow increased water flux at higher flow rate. The water flux of FO membrane increased with increasing draw solution concentration from 10000 to 30000 mg/L. The water flux for $KH_2PO_4$ draw solution was similar to that for commercial fertilizer. Optimization of FO process would contribute to economically desalinate brackish water for agricultural use.

목적: 암환자에서는 비타민 D 결핍이 흔하지만, 생애 말기암환자에서 비타민 D 결핍 현황에 대한 자료는 드물다. 저자는 말기암환자를 대상으로 비타민 D 결핍 현황 및 그와 관련된 인자를 파악하고자 하였다. 방법: 일개 호스피스 병동에 입원하였던 말기암환자 133명을 대상으로 후향적 의무기록 관찰을 토대로 진행되었다. 환자의 나이, 성별, 혈중 비타민 D 수치, 암 종류, 신체기능, 약물, 그리고 혈액검사에 대한 자료를 수집하였다. 잠재적인 혼란변수를 보정한 후, 다변량 분석을 통해 혈청 비타민 D 결핍과 연관된 유의한 변수를 확인하였다. 혈청 비타민 D 수치 20 ng/mL 미만을 결핍, 10 ng/mL 미만을 중증 결핍으로 간주하였다. 결과: 대상자의 95%는 혈청 비타민 D 결핍증 상태였다. 남성, 비폐암 환자, $H_2$ 차단제 사용자, 항경련제 미사용자에서 중증 비타민 D 결핍이 더 흔하였다. 혈중 alanine aminotransferase (ALT) 상승 또한 낮은 비타민 D 수치와 관련이 있었다. 다변량 분석에서 중증 비타민 D 결핍이 있을 가능성은, 남성이 여성에 비해 3.82배(95% CI: 1.50~9.72, P=0.005), $H_2$ 차단제를 사용한 환자가 그렇지 않은 환자에 비해 3.94배(95% CI: 1.61~9.65, P=0.003), ALT상승이 있는 환자는 그렇지 않은 환자에 비해 4.52배(95% CI: 1.35~15.19, P=0.015)였다. 결론: 말기암환자에서 비타민 D 결핍 상태는 매우 흔했다. 남성, $H_2$ 차단제의 사용, 그리고 ALT의 상승이 중증 비타민 D 결핍과 관련이 있었다. Purpose: Although vitamin D deficiency is more commonly found in cancer patient than in non-cancer patients, there have been little data regarding the prevalence of vitamin D deficiency in cancer patients at the very end of life. We examined vitamin D deficiency in terminally ill cancer patients and related factors. Methods: This study was based on a retrospective chart review of 133 patients in a hospice ward. We collected data regarding age, sex, serum 25-hydroxyvitamin D level, cancer type, physical performance, current medications and various laboratory findings. We investigated factors related to serum vitamin D levels after multivariate adjustment for potential confounders. Serum 25-hydroxyvitamin D<20 ng/mL was considered deficient and <10 ng/mL severely deficient. Results: Ninety-five percent of the patients were serum vitamin D deficient. Severe vitamin D deficiency was more common in male patients, non-lung cancer patients, $H_2$ blocker users and non-anticonvulsant users. Elevated levels of serum alanine aminotransferase (ALT) were also associated with low serum vitamin D levels. Multiple regression analysis showed that severe vitamin D deficiency was associated with male gender (aOR 3.82, 95% CI: 1.50~9.72, P=0.005), $H_2$ blocker users (aOR 3.94, 95% CI: 1.61~9.65, P=0.003) and elevated serum ALT levels (aOR 4.52, 95% CI: 1.35~15.19, P=0.015). Conclusion: Vitamin D deficiency was highly prevalent among terminally ill cancer patients. Severe vitamin D deficiency was more common in male patients, $H_2$ blocker users, and patients with elevated ALT levels.
