  • A 12-w feeding trial was conducted with 600 38-wk-old layers to evaluate the nutritive value of high oil corn(HOC) in layer diets. For the control, a commercial corn-soybean meal basal diet was used. An iso-calorie diet(HOC-ISO) was prepared replacing corn with HOC in the control diet. In addition a third diet was prepared by simply replacing corn with HOC on 1:1 basis to give a high energy diet(HOC-1:1). There were 5 replicates per treatment, and 40 birds per replicate. Birds were housed in an open-sided layer house equipped with wire cages. Feed and water were provided ad libitum, and 17L:7D lighting program was adopted. No significant difference (P>0.05) was found among dietary treatments in laying performance. Also physical qualities of eggs were not significantly affected by the feeding of HOC. Although not significant, HOC-ISO tended to improve the laying rate during the summer. The HOC feeding significantly increased the polyunsaturated fatty acids contents in egg yolk, especially the linoleic acid The AME contents of Chinese yellow corn, U.S. corn, and HOC were 3177, 3158 and 3387 kcal/kg respectively.

  • The aim of this study is to evaluate the microbial safety and physical qualities of Korean jerky, and the effect of nisin during storage. Jerky processed packages with or without nisin (100 IU or 500 IU) were stored at room temperature (25 $^{\circ}C$) for 60 days, and samples measured for quality at regular intervals throughout this storage period. In the case of 25$^{\circ}C$ storage, the number of mesophilic microorganisms in seasonedbeef packages without nisin increased markedly, but with nisin there was no observed increase. B. cereus cells showed similar trends, although coliform was not detected in all samples. At 25$^{\circ}C$ storage, changes in the cutting force of packages containing nisin showed no significant change, packages without nisin decreased markedly.

  • Purpose - Could blood type provide the key to wellness and affect our personality? The theory that blood type is linked to personality (and other mental and physical qualities) is popular mostly in Japan, although it has carried over to Taiwan and South Korea. Research Design, Data, and Methodology - Questionnaires were distributed to 380 production line company employees. The reliability and validity of the questionnaires were examined through independence testing and the average ratio comparison of the two populations. Additionally, using Pearson's chi-square formula, the relationship between the blood group (independent variable) and general group participation (dependent variable) was tested along with the Schuprow coefficient. Result - The prioritization of blood groups over the general group participation was identified and the following results were obtained: Individual group participation is affected by personality features derived from temperament, mood, and other characteristics. Conclusion - The study showed that individual blood groups have an effect on their group cooperation, and among blood groups, blood group A had the greatest tendency to group participation, followed by blood groups O, AB, B, respectively.

  • This study was objected to provide suggestions for best management practices to restore the cultural and historical values of the wells in Palaces as well as their water qualities. Water resources in the five Palaces in Seoul Metropolitan, including Gyeongbokgung, Changdeokgung, Changgyeonggung, Jongmyo Shrine, and Deoksugung, were surveyed for their physical flows and chemical compositions from April to July in 2010. Ground waters in most wells were found at depths within 5 m from the ground surface, showing typical water-table aquifer systems. Hydraulic gradients indicate water resources in Gyeongbokgung, Changdeokgung, and Changgyeonggung flowing toward south, and toward east in Deoksugung area. Especially, water-level fluctuation data at S-10 in Deoksugung implied the influence of groundwater discharge facility. In Jongmyo Shrine, water was not detected in wells, indicating the water level was lower than the well depth. Based on the water chemistry and stable isotope analyses, water resources and their qualities appeared to be formed by the water-rock interaction along the groundwater paths. S-10 (Deoksugung) and S-14 (Changgyeonggung) samples were contaminated with nitrate ($NO_3$) in levels of higher than Korean drinking water standard, 10 mg/L as $NO_3$-N, but once in four sampling campaigns. In the situation that water resources in Palaces still maintain natural characteristics, the materials that will be used for the restoration and improvement of the Palace water supplies should be carefully selected not to disturb the natural integrity. In addition, because the wells are located in the center of metropolitan area, a systematic monitoring should be applied to detect and to manage the potential impacts of underground construction and various pollution sources.

  • 이 연구는 놀도프-로빈스 음악치료사 1단계 훈련과정에서 치료사의 내담자였던 15q 염색체중복 증후군(Chromosome 15q Duplication Syndrome)을 가진 E와의 치료사례에 대한 놀도프-로빈스 훈련과정에서 요구되는 형식의 임상사례연구로, 그 주요 내용은 내담자의 변화와 성장뿐만 아니라 치료과정 전반에 걸친 치료사의 경험과 이를 통한 치료사의 변화와 성장도 포함한다. E는 정신적, 신체적 영역에서 도움이 필요한 내담자였고 치료사는 E와의 치료과정에서 많은 시행착오를 겪었다. 이러한 경험을 통해 치료사는 내담자를 더욱 깊이 이해하게 되었고 음악치료사의 역할에 대한 새로운 시각을 얻을 수 있었다. 매 회기마다 상이하고 다양한 반응을 보였던 E와의 치료를 진행하면서 치료의 조직화(organization)에 대한 많은 고민이 있었고, 이에 대한 적절한 설명을 위해 놀도프-로빈스 음악치료의 다양한 이론들 중 Aigen(1996)의 '임상적-음악적 상호작용의 질'을 채용하였다.

  • Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demo-sociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder. Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study. Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The elderly with physical debilities experienced less limitation in food chewing and swallowing, and pronunciation than ones capable of living at home. On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition. By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years, and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city. Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type. Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly's current status, age, living area, medical security type.
