The world has witnessed a phenomenal growth in information and communication technologies (ICT). The development of new broadband communication services convergence of telecommunication with computers and recent developments in the field of communication protocol have fostered challenges as well as offerings in the wide-ranging use of ICT to support the creation of dynamic and interactive teaching and learning environment. By emergence of ICT, most of education and training institutions are struggling to integrate ICT and education and training systems. It is so important to apply proper delivery systems for utilization of the computerized teaching and learning contents in the classrooms. It will be a preliminary activity for building open and flexible distance teaching and learning systems in developing countries. In this paper, we would like to suggest and recommend the proper delivery systems for utilization of the computerized teaching and learning contents in the classrooms for education sector reform in developing countries.

미디어 컨버전스 환경 속에서 디지털 영화는 주요한 콘텐츠 공급원이자 강력한 문화적 파급력을 지닌 콘텐츠로 각광받고 있다. 이에 디지털 영화는 극장 이외에도 공중파 방송, 케이블 TV, 인터넷, 모바일 등으로 그 상영 플랫폼을 확장해 가고 있다. 본 연구는 위의 미디어들을 1차 플랫폼으로 하여 제작, 상영된 디지털 영화의 현황을 다양한 사례를 중심으로 살펴보고 그 형식적, 내용적 특징들을 분석한다. 이를 통해 상영 플랫폼 분화에 따른 디지털 영화의 특징변화를 연구하고 급변하는 환경 속에서 디지털 영화 콘텐츠가 나아갈 방안을 모색한다.

The purpose of this study was to investigate differences of Ca, Mg and Zn utilization in young and adult rats fed standard diet for 3 weeks. Feed intake and body weight gain in young rats were significantly higher than in adult. There were no significant differences in serum levels of Ca and Zn across age and sex. In liver of young or male groups, Ca and Zn contents were significantly higher than in adult or female. There were no significant differences in tibia contents of Ca and Mg, but Zn content was increased when young or female groups was compared with the other groups. In mineral balances, daily intakes and retentions of Ca, Mg and Zn in young or male groups were significantly higher than those in adult or female. According to this results, it could be suggested that in growth period must be increased dietary intake of Ca, Mg and Zn to compromise the requirement for growth.

This study was conducted to examine the effects of dietary cellulose levels on growth, nitrogen utilization, the retention time of diets in the digestive tract, and caecal microflora of 2-month-old Single Comb White Leghorn male chickens fed 3 purified diets that contained 0, 3.5% and 10% cellulose in equal amount of nutrients for 7 days. Body weight gain and nitrogen utilization were significantly higher (p<0.05), while total microflora counts in the caecal contents and retention time of the diet in the digestive tract were significantly lower (p<0.05) in the group fed 3.5% dietary cellulose compared with the group fed 10% dietary cellulose. Body weight gain, nitrogen utilization and retention time of the diet in the digestive tract decreased significantly while the total microflora count in the caecal contents increased significantly in the group fed 10% dietary cellulose compared to the group fed 0% dietary cellulose (p<0.05). Chickens fed 10% dietary cellulose had significantly increased counts of uric acid-degradative bacteria such as Peptococcaceae and Eubacterium, including Peptostreptococcus (p<0.05). The results suggest that cellulose in purified diets is an effective ingredient and the effects on growth, nitrogen utilization, caecal microflora counts and diet retention time in the digestive tract are dependent on the inclusion rate. Positive or negative effects of dietary cellulose are displayed by growth, nitrogen utilization, caecal microflora counts and retention time of the diet in the digestive tract. Positive effects were displayed when the inclusion rate is 3.5% and negative effects were displayed when that is greater than 3.5% of the diet, and the phenomenon is without reference to the age of the chickens.

의약품을 사용할 때 나타나는 부작용은 국민의 건강을 크게 위협할 수 있다. 현재 의약품 부작용에 대한 보고가 매우 미흡한 것이 현실이다. 이에 현재 약국에서 사용하고 있는 의약품 사용평가(DUR:Drug Utilization Review)에 의약품 부작용 보고를 연계하게 된다면 활성화될 수 있다. 의약품 사용평가가 활성화되어 있는 미국 의약품 관리 체계 연구를 통해 의약품 부작용 보고 활성화 방안을 찾을 수 있다. 약국에서 의약품 관리 프로그램으로 사용되는 'Pharm IT 3000'에서 의약품 부작용 보고의 활성화 방안을 연구해 보았다. 문헌연구와 실제 프로그램 운영 방식 연구를 통해 Pharm IT 3000 처방 조제 현황 항목에 의약품 사용평가를 연동시켜 부작용 보고가 편리하게 되는 방안을 찾게 되었다.

본 연구는 국내에서 최고의 고급육으로 유통되는 한우고기의 부위별 성분조성 및 육질특성을 조사하고자 $1^{++}$ 육질등급을 받은 거세한우 10두에서 10부위(업진, 보섭, 채끝, 등심, 꾸리, 홍두깨, 목심, 설깃, 양지, 우둔)를 선정하여 성분조성 및 육질특성을 분석하였다. 10부위간에 칼로리 함량은 $2,205{\sim}3713.20\;cal/g$ 범위였으며 특히 등심, 채끝 및 업진부위가 다른 부위들과 비교하여 유의적으로 높은 것으로 나타났다(p<0.05). 콜레스테롤 함량도 $38.86{\sim}44.69\;mg/100g$ 수준으로 10부위 중에서 목심부위가 유의적으로 가장 높았고 홍두깨와 우둔부위가 다른 부위와 비교하여 유의적으로 가장 낮은 것으로 분석되었다(p<0.05). 가용성 및 불용성 콜라겐 함량에 있어서는 부위별로 유의적인 차이가 없었으나 총 콜라겐 함량은 꾸리, 목심 및 설깃부위가 가장 높았고 등심 및 채끝부위가 가장 낮은 것으로 나타났다(p<0.05). 맛과 관련이 있는 유리아미노산함량을 부위별로 비교한 결과 모든 부위에 glutamate와 alanine 함량이 각각 $275.99{\sim}536.04\;mg/100g$, $130.63{\sim}175.23\;mg/100g$으로 가장 높은 수준이었고 다음으로 arginine($7.00{\sim}10.49\;mg/100g$), phenylalanine($4.70{\sim}13.88\;mg/100g$), leucine ($5.98{\sim}10.26\;mg/100g$) 순으로 나타났다. 부위별 adenine diphosphate(ADP) 함량은 유의적인 차이가 없는 것으로 나타났으나(p>0.05). Adenine mono phosphate(AMP)는 보섭과 목심 부위에서 모두 1.09%로 다른 부위보다 유의적으로 가장 높게 나타났다(p<0.05). Inosine monophosphate(IMP)는 흥두깨 및 우둔부위가 각각 30.04, 33.44%로 다른 부위보다 유의적으로 가장 많았으며(p<0.05), inosine 함량은 보섭, 흥두깨 및 우둔부위가 각각 6.19, 6.25, 6.28%로 가장 많았고 반면에 hypoxanthine은 4.27%인 꾸리부위에서 가장 높게 나타났다(p<0.05). $1^{++}$ 등급 거세한우의 부위별 지방산 조성을 분석한 결과 C16:1n7, C20:3n6, C20:4n6을 제외한 부위별 지방산 조성은 유의적으로 차이가 없는 것으로 분석되었다(p>0.05).
