        본 연구는 멕시코에 진출한 국내 다국적기업 해외자회사의 기업의 사회적 책임(corporate social responsibility; 이하 CSR) 활동이 현지 근로자들의 정서적 몰입을 통해 창의적 행동에 미치는 영향을 고찰하였다. 더불어 정서적 몰입이 창의적 행동에 미치는 긍정적인 효과를 촉진시키는 상황조건으로서 평가 공정성 및 직무 자율성을 제시하 였다. 선행연구들은 기업의 CSR 전략이 기업수준의 성과변수에 미치는 영향에 주로 초점을 맞춘 반면, 기업의 해외 진출 경쟁이 치열함에도 불구하고 해외자회사의 CSR 활동에 대한 현지 직원들의 실제 인지 수준을 측정하여 개인수준에서 매우 중요한 변수인 창의적 행동으로 연결되기까지의 메커니즘과 상황조건에 대해 심도있게 고찰한 연구는 상당히 미비하다. 이에 본 연구에서는 현지 경영활동에서 외국인 비용을 극복하는데 중요한 전략이 될 수 있는 현지 CSR 활동과 조직 내부의 제도적 요인들이 현지 근로자들의 창의적 행동에 미치는 효과를 개인수준에 서 통합적인 관점으로 살펴보는데 주목하였다. 멕시코 현지 근로자 192명을 대상으로 분석을 실시한 결과, 현지 직원들이 인지하는 해외자회사의 CSR 활동은 그들의 정서적 몰입과 정의 관계를 나타냈으며, 정서적 몰입은 창의적 행동과 정의 관계를 보였다. 더불어 인지된 해외자회사의 CSR 활동과 창의적 행동 간의 관계에서 정서적 몰입의 매개효과 역시도 통계적으로 유의하였다. 또한, 정서적 몰입에 대한 인지된 평가 공정성 및 인지된 직무 자율성의 조절효과는 창의적 행동에 각각 유의한 것으로 나타났다. 구체적으로 인지된 평가 공정성 및 인지된 직무 자율성이 높은 그룹에서만 정서적 몰입과 창의 적 행동이 강한 정의 관계를 나타냈다. 이러한 연구결과를 토대로 다국적기업 해외자회사의 현지화 전략에 대한 의미있는 이론적 및 실무적 시사점을 제공한다.

        자기공명영상(MRI) 장비의 조영제로 흔히 사용되는 가돌리늄(Gd)은 매우 안정된 상태로 하수처리과정에서 거의 제거되지 않고 수환경으로 유입된다고 알려져 있다. 따라서 본 연구에서는 세 가지의 공법으로 하수처리를 하는 부산 수영 하수처리장에서 채취한 하수 시료의 공정별 용존 희토류 원소의 제거율 및 수환경으로 배출되는 인위적 기원 Gd (Gdanth)의 배출량을 평가하고자 하였다. 용존 희토류 원소는 공정별 처리 단계에 따라 무거운 희토류 원소(Tb-Lu)에 비 해 가벼운 희토류 원소(La-Eu)에서 농도가 감소하는 경향을 보였다. 또한 일부 시료에서 나타난 음의(negative) Sm anomaly (<1)는 생물학적 제거 과정에서 Sm이 입자나 인산염과 흡착되어 함께 제거되었을 가능성을 시사한다. 모든 시 료에서 양의(positive) Gd anomaly (149±50, n=9)를 보였으며, 공정별로 측정된 Gd의 총 농도 중 Gdanth은 약 97% 이 상을 차지하는 것으로 나타났다. 이는 하수처리과정에서 Gdanth 이 거의 제거되지 않고 수영강 하류로 배출된다는 것을 의미한다. 일별 처리용량을 고려하여 각 공정에서 배출되는 Gdanth의 배출량은 259 mmol/day로 추정할 수 있다. 본 연 구의 결과는 하수처리장을 통해 수영만 연안으로 Gdanth이 지속적으로 배출될 것으로 예상되며, 향후 Gd의 중장기적인 관측이 필요함을 시사한다.

        혈관육종은 연부조직에서 기원하는 매우 드문 종양인데 간담도계에서 발생하는 혈관육종은 더욱 드물다. 혈관육종은 증상이 비특이적이고 진단도 어렵기 때문에 발견 당시 이미 병기가 진행된 경우가 많으며 예후도 나쁘다. 저자들은 우측 상복부 통증으로 내원하여 총담관 혈관육종으로 진단 된 증례를 경험하였다. 총담관에서 기원한 혈관육종은 현재 까지 보고된 바가 없기에 문헌고찰과 함께 보고하는 바이다.

        There is no doubt that global warming and climate change affect animal production and sustainability of livestock systems. High ambient temperature and humidity have detrimental effects on the performance of laying hens. The aim of this study was to evaluate the influence of cyclic temperatures on the performance and egg quality of laying hens during the summer in Korea. A total of 1028 Hy-Line Brown layers were reared in the open floor house and exposed to a 24 hr linear temperature cycle ranging from 21.7 to 33.0℃. Feed intake significantly decreased and cracked eggs increased under high ambient temperature or high THI (Temperature Humidity Index). Egg production was decreased gradually from 21 to 29℃ or from 21 to 26 THI. On the other hens, it was increased above 30℃ or 27 THI rather than decreased. High ambient temperature has no important impact on dirty eggs and mortality in this study. We believe that present data contribute to predict the effect of thermal conditions on the performance of laying hens by using ambient temperature or THI

        This study was conducted to investigate the effect of dietary sericite(SC) on laying performance, feed conversion ratio, egg quality and fecal ammonium nitrogen. Three hundreds and sixty 92-wk-old, Lohman Lite layers were randomly divided into 20 groups of 18 birds each and assigned to five experiment for 4 weeks (72 birds per treatment). Dietary treatments were Control (control diet), SC 0.5 (control diet +0.5% sericite), SC 1.0 (control diet +1.0% sericite), SC 1.5 (control diet +1.5% sericite), and SC 2.0 (control diet +2.0% sericite). Hen-day egg production tended to increase by the SC 1.0%, SC 1.5% and SC 2.0% supplementation in the diets. Egg weight also tended to increase by the SC 1.0% addition in the diets. Feed intake was increased (p<0.05) in SC 1.5 and SC 2.0 but feed conversion was improved (p<0.05) only in SC 1.0 (p<0.05). Digestibility of nutrients were not linearly affected by dietary supplementation of sericite although there was an inconsistent difference. Egg shell strength, albumin height, yolk color, and egg shell thickness were not affected (p<0.05) by treatments. Fecal NH3-N concentration was decreased (p<0.05) by dietary sericite supplementation compared to control. This study showed that dietary 1.0% sericite supplementation can be beneficial to improve egg production, egg weight and feed conversion and to decrease fecal NH3-N concentration.

        This study was conducted to investgate the effect of gamma irradiation on the lipid oxidation, olfactory properties, fatty acid isomer and volatile compound profiles of five different oil sources. Three plant oils, canola oil, corn oil and soy oil, and two animal fat, tallow and fish oil, were irradiated with 0, 5, 10, and 20 kGy level of dose by Co-60 as a radiation source. Lipid oxidation parameters, FFA, POV and TBARS, were determined according to the AACC and AOCS method. Olfactory property of irradiated oil sources was analyzed using electronic nose (FOX3000, AlphaMOS Co., France) with 12 metal oxide sensors and the result was interpreted using principle component analysis program. Fatty acid isomer profiles and volatile compound profiles of irradiated oils were also measured by GC and GC-MS, respectively. Although the free fatty acid level of oil were the highest by high dose level (20 kGy) of irradiation, changes of both TBARS and POV values by gamma irradiation were varied between oil sources and irradiation level of dose. Electronic nose analysis showed a distinct difference among dose levels of irradiation. Although there was no new volatile compound produced by gamma irradiation, amounts of each volatile compounds were increased by irradiation. Only cis isomer, 9c12c15c of linolenic acid was dose-dependently decreased as irradiation level increased but there was no difference among other isomer profiles of linoleic acid and linolenic acid by gamma irradiation. This study showed that changes in physico-chemical properties of both plant and animal oil were remarkable by gamma irradiation. Therefore, a further study should be needed to scrutinize the interaction among lipid oxidation, production of volatile compounds and off-flavor, and isomerization of fatty acid by gamma-irradiation.

        This study was conducted to evaluate the effect of dietary Yanggu original white kaolin supplementation on the growth performances, nutrients utilizability and meat composition of broiler. A total of 260 broiler chicks was alloted to 5 treatments with 4 replications and 13 chicks per replication. In addition to control group that fed diet without any kaolin supplementation, the treatments are designated by dietary supplementation as follows; white kaolin 400 mesh 1%(T1), white kaolin 10,000 mesh 1%(T2), white kaolin 400 mesh 0.8% + probiotics 0.2%(T3) and kaolin rizen(T4). The specific volume of 10,000 mesh white kaolin was higher than that of 400 mesh white kaolin (p<0.05) with no difference in pH between two different size white kaolins. Pellet durability of kaolins supplemented diet was improved, regardless of fat addition, compared to that of no kaolin supplemented diet. Both weight gain and feed intake of broilers in all the kaolin supplemented treatments were higher than that of control during d 0~21 period (p<0.05) but with no differences during d 22~40, On the other hand, kaolin supplementation into the control diet did not affect F/G of young broiler during d 1~21. Overall F/G of broiler was decreased by kaolin supplementation. Although there was no difference on ether extract, crude ash, total CHO and dry matter utilizabilities among all treatments, both crude protein and energy utilizabilities were improved by kaolin supplementation. Crude protein content of both broiler thigh and breast was the lowest in the kaolin and probiotics combined supplemented group(T3). In conclusion, the supplementation of physico-chemically treated white kaolin does affect growth performances, nutrients utilizability and meat composition of broilers. Therefore, the kaolin can be considered as a beneficial feed additive to improve broiler productivity.
