사료 내 유기태 미네랄, carnitine 및 taurine의 첨가에 의한 산란계의 생산성 및 계란 내 이행에 관한 연구
Three experiments were conducted to develop dietary regimes for transference of dietary trace minerals and bioactive substances into chicken egg by supplementing Cu, Se, carnitine and taurine into laying hen feeds. Experiment 1 was conducted using 350 Lohmann Brown layers (67 week of age) to evaluate the dietary effect of organic or inorganic Se and Cu on their contents in chicken eggs. The layers were divided into seven groups and fed a commercial diet or one of the six experimental diets containing different levels of Se and Cu (T1, organic Se 0.3ppm; T2, organic Se 1.0ppm; T3, inorganic Se 1.0ppm; T4, organic Cu 125ppm; T5, organic Cu 250ppm, and T6, inorganic Cu 250ppm) for 5 weeks. No significant differences were observed among the groups in egg production and its qualities. The contents of blood cholesterol of the birds fed various levels of Se and Cu were not significantly different as compared to that of the control. The Se contents of eggs were linearly increased as dietary Se level increased for both sources, but Se content from the groups fed organic Se were slightly higher than that fed inorganic Se. The sensory characteristics of eggs were not influenced by the dietary treatments. Experiment 2 was conducted using 120 Hy-Line Brown layers (50 week of age) to evaluate the effect of supplemented carnitine with different levels on its transfer into eggs. The layers were divided into four treatment groups and fed commercial diet or experimental diets containing synthetic carnitine(0.04%, 0.1% and 0.2%) for 6 weeks. Egg production and egg mass in the groups fed the diet containing 0.1% synthetic carnitine were significantly increased more than those of control(p<0.05). No significant differences in eggshell qualities and egg yolk cholesterol content were observed among the groups. The triacylglycerol contents of egg yolks in groups fed the diets containing carnitine were reduced as compared to that of control, but not significantly. The carnitine contents of egg yolk were linearly increased as dietary carnitine levels increased. The sensory characteristics of eggs were not influenced by the dietary treatments. Experiment 3 was conducted using 150 Hy-Line Brown layers (50 week of age) to evaluate the dietary effect of various supplemental levels from squid liver powder (SLP) and synthetic taurine on their transfer into eggs. The layers were divided into five treatment groups and fed commercial diet or experimental diets containing 2% SLP, 2% SLP+0.02% synthetic taurine, 0.04% synthetic taurine or 0.2% synthetic taurine for 6 weeks. The egg weights in groups fed diets containing SLP or synthetic taurine tended to be reduced. No significant differences in eggshell qualities were observed among the groups. Egg production and egg mass in the groups fed diets containing SLP and synthetic taurine, except T2 group, were significantly increased as compared with those of control(p<0.05). The contents of taurine in the groups fed diet containing synthetic taurine above 0.04% were significantly increased compared to the control group. No significant differences were observed among the groups in egg cholesterol. But, the triacylglycerol contents of egg yolks in the groups fed the diet containing taurine tended to be reduced compared to the control. The sensory characteristics of eggs were not influenced by the dietary treatments. In conclusion, Se content of eggs were linearly increased as dietary levels of organic or inorganic Se increased, but eggs in layers fed containing organic Se had slightly more Se than those of groups fed inorganic Se. The contents of synthetic carnitine levels of egg yolk were linearly increased as dietary carnitine level increased. The results from this study indicated that the use of synthetic taurine in layer diets was more effective for increasing the taurine contents of egg. 본 연구는 셀레늄, 구리, 카르니틴과 타우린을 이용하여 미량광물질 및 생리활성물질을 계란 내에 축적하는 연구를 목적으로 수행하였다. 실험 1에서는 산란계 사료에 셀레늄과 구리의 첨가가 난 생산성과 이들 성분의 계란 내 이행에 미치는 영향을 조사하기 위해 수행하였다. 대조구와 유기태 셀레늄 0.3 ppm을 첨가한 T1, 유기태 셀레늄을 1.0 ppm 첨가한 T2, 무기태 셀레늄을 1.0 ppm을 첨가한 T3, 유기태 구리 125 ppm을 첨가한 T4, 유기태 구리 250 ppm을 첨가한 T5 및 무기태 구리 250 ppm 첨가한 T6 처리구로 구성하였고 67주령의 Lohmann Brown 산란계 암컷 350수를 공시하여 5주간 실험을 실시하였다. 생산성과 난각질은 처리 간에 큰 차이가 없는 것으로 나타났다. 혈액 콜레스테롤 수준은 셀레늄과 구리의 첨가에 따라 대조구에 비해서 큰 차이가 없었다. 셀레늄는 사료 내 첨가 수준이 증가함에 따라 계란 내 이행량도 비례하여 증가한 것으로 나타났다. 또한 유기태 셀레늄과 무기태 셀레늄 처리구에서는 유의한 차이는 없었으나, 유기태 셀레늄 처리구에서 무기태 셀레늄 처리구에 비해 다소 높았다. 기타 관능검사는 유의한 차이를 발견할 수 없었다. 실험 2에서는 산란계 사료에 합성 카르니틴의 첨가수준에 따른 급여가 산란계 생산성과 계란 내 이행에 미치는 영향을 조사하기 위해 수행하였다. 대조구와 합성 카르니틴을 다양한 수준(0.04%, 0.1%과 0.2%)으로 첨가 급여하는 실험구로 구성하였고 50주령의 Hy-Line Brown 산란계 암컷 120수를 공시하여 6주간 실험을 실시하였다. 산란율은 합성 카르니틴을 0.1%를 첨가하여 급여한 처리구에서 가장 높았고, 대조구에서 가장 낮은 결과가 관찰되었다. 일산란량은 합성 카르니틴 0.1% 이상 첨가 급여한 처리구에서 대조구 및 합성 카르니틴 0.04%를 첨가하여 급여한 처리구에 비해 유의하게 증가하는 결과가 관찰되었다. 난각질은 처리 간에 차이가 없는 것으로 나타났다. 난황 내 중성지방은 카르니틴의 첨가구에서 대조구에 비해 유의차 없이 감소하였다. 대조구에 비해 합성 카르니틴을 첨가 급여한 모든 처리구에서 난황 내 카르니틴 함량이 비례하여 증가한 것으로 나타났다. 계란의 관능적 특성에는 부정적인 영향이 없는 것으로 나타났다. 실험 3에서는 타우린의 첨가형태(squid liver powder, SLP와 합성 타우린)와 첨가수준에 따른 산란계의 생산성과 계란 내 이행에 미치는 영향을 조사하기 위하여 수행하였다. 대조구와 SLP를 2.0%, SLP 2.0%+합성 타우린을 0.02%, 합성 타우린 0,04%, 합성 타우린 0.20%를 첨가 급여하는 실험구로 구성하였고 50주령의 Hy-Line Brown 산란계 암컷 150수를 공시하여 6주간 실험을 실시하였다. 사료섭취량에서는 처리 간에 차이가 없었으나, 산란율과 일산란량은 합성 타우린 0.04%를 첨가급여한 처리구를 제외하고 타우린을 첨가한 모든 처리구에서 대조구에 비해 유의하게 증가하였다. 대조적으로 난중은 대조구에 비해 SLP나 합성 타우린을 급여한 처리구에서 감소하는 경향이 관찰되었다. 난황 내 타우린의 함량은 합성타우린을 0.04% 이상 첨가한 처리구(합성 타우린 0.04%와 0.2%)에서 유의하게 증가하는 결과가 관찰되었다. 난황 내 총 콜레스테롤 함량에서는 처리 간에 큰 차이가 없었으나 중성지질 함량은 대조구에 비해 모든 처리구에서 감소하거나 감소하는 경향을 보여주었다. 인지질 함량에서는 처리 간에 변화는 없었다. 타우린의 첨가에 따른 계란의 관능적 특성에서는 처리 간에 큰 차이가 없는 것으로 나타났다. 이상에서와 같이 계란 내 셀레늄 수준은 산란계 사료 내 셀레늄 첨가 수준이 증가함에 따라 비례하여 증가하였으며, 유기태 셀레늄의 첨가 급여가 무기태 셀레늄에 비해 계란 내 이행에 비교적 유리하다는 결과가 관찰되었다. 합성 카르니틴 또한 계란 내 이행이 가능한 영양소로서, 첨가 수준에 비례하여 계란 내 함량이 증가하였다. 타우린 강화계란의 생산에는 타우린이 함유된 천연 원료의 공급보다 합성 타우린의 공급이 계란 내 이행에 더 효과적이라는 결과가 관찰되었다. 이러한 연구결과는 셀레늄, 카르니틴 및 타우린을 함유한 기능성 계란은 사람에게 이들 성분의 유용한 공급원으로서 제공될 수 있을 것이다. 또한 산란계에서 생산성에 부정적인 영향이 없다는 결과와 관능적 특징에 영향이 부정적인 영향이 없다는 결과는 계란 내 유효성분을 이행시켜 고부가가치 계란을 생산하는 산업적 기능성 계란에 중요한 자료가 되리라 판단 되었다.

It is being thought that the background of regular discussion for the introduction of the domestically new real estate financial systems like ABS, MBS and REITs has been under the biggest influence of the assets deflation caused from post-IMF chaos. In order to block the link to combined depression after the IMF's managing system, the government had come to introduce the real estate stock system and liquidization system as one of stable measures. Real estate investment trust system, particularly, initiated to build up the bill set to be enforced in the year 2001 is about to bring an enormous effect on the real estate market nationally when practicing the comparative analyzing to the cases of the US., Australia and Japan. REITs is a great product to allow the opportunity for small time investors to participate in big scale real estate investment but the problems such as price increase and speculation on real estate, lack of producing cost in manufacturing sector, shortage of professional personnel institution and investors' loss rising up and finally worries over excessive heat of early market would arise in introducing the system. The methods to minimize the problems and effectively introduce the REITs system is as, The first, to strengthen the protective tool for investors and to minimize the side effects expected from introducing the system. By strengthening the authorities of general meeting of shareholders and committee for investors to securely invest, it is to protect the right and interest of small amount shareholders and to minimize the expected side effects, gradual and conservative introduction of the system and gradual inducement of being activated later on is advised. Secondly, within the range of not infringing the security of management of real estate company, to permit the development business to a certain extent. Even if the law is enacted, it would have to be operated without a hitch by enacting the regulations Korean-wise. Thirdly, the atmosphere for the right function of the real estate stock market is necessary and the government must establish fairly and clearly the applying rules within the real estate finance market. Considering that the real estate finance market is the currently new one, in early days, active taxation support is requested. And to promote the atmosphere of the economical subject and object in possible kind of diversity who can act in the real estate finance market. And finally, to encourage the REITs system in the nation, introducing the UP REITs and to training to develop the professional real estate investment company personnel is indispensable. Besides, appropriate supplementary plans to cultivate the real estate related business along with associated systems improvement should be followed. Hopefully, there would be continual study on taxation support and the volition to early settlement of the government to introduce the system suitable to our conditions to which one desperately request. The REITs system promotes in the long run the structure adjustment and enlightens the capital market and simultaneously bring advancement to the real estate market to greatly contribute to uplift the efficiency of the nation's economy as we would all wish to be accomplished.
Debussy의 <Estampes>에 나타난 인상주의 음악의 특징과 표현에 관한 연구 : 2011. 4. 26 렉쳐 리싸이틀을 중심으로
본 논문은 프랑스의 인상주의 작곡가 드뷔시(1862-1918)의 피아노 작품 <Estampes(판화)>가 가지고 있는 인상주의적 특징과 표현 방법들을 연구하여 2011년 4월 26일 렉처 리사이틀을 통해 피아노 연주와 함께 발표하였던 내용을 수정 보완한 것이다. <Pagodes(탑)>, <La Soiree dans Grenade(그라나다의 황혼)>, <Jardins Sous La Pluie(비 오는 날의 정원)>의 총 3곡으로 구성된 <Estampes(판화)>는 3곡이 각각 다른 나라를 배경으로 하고 있는데, 첫 번째 곡은 동남아시아의 안개 낀 사원을, 두 번째 곡은 스페인 골목의 저무는 황혼을, 세 번째 곡은 프랑스 정원에 내리는 비의 다양한 모습을 떠올리게 한다. 이러한 <판화>의 작곡배경과 함께 음악적 영향에 바탕을 둔 드뷔시의 생애와 드뷔시의 인상주의적 특징들에 관해 살펴보았고, 각 곡 마다 개성이 잘 드러날 수 있도록 각각의 곡이 가지고 있는 독특한 특징들을 연구하였다. 또한 인상주의적 색채를 효과적으로 표현하기 위해 페달 사용 방법에 대해 연구하였고 이러한 연구 결과를 통해 피아노 연주자들이 작품의 음악적 특징, 인상주의적 색채를 표현하는데 있어 보다 효과적으로 연주를 하는데 도움을 주고자 하였다. This study comprises the research results on the impressionism features and expression methods of <Estampes>, a piano piece of French impressionism composer Debussy. This study is based on research, the contents of a lecture recital from April 26 2011, along with other piano performance that helped to supplement the study. <Estampes> consists of 3 pieces in total: <Pagodes>, <La Soiree dans Grendade> and <Jardins Sous La Pluie>. Each piece was set in different country. The first one brings an image of a temple in a foggy southeastern Asian country. The second is reminiscent of twilight in a Spanish alley whilst the third one arouses various looks of rain drops falling on a French garden. For this study, evaluating the background of <Estampes> and Debussy’s life and his impressionism features based on musical effect were studied. Additionally, research on the unique characteristics of these pieces was conducted to see their individual distinct features. Pedal usage was examined for effective expression of impressionism overtones as well. Based on all the results above, this study aimed to help piano players express the musical features and impressionism color in these pieces more effectively.

ABSTRACT The Development and Effects of the Program for Promoting Young Children's Participation Rights Based on Decision-Making Learning Model Name: Park Tae-Soon Academic Advisor: Kim Seung-Hee Department of Early Childhood Education Graduate School of Gwangju University The purpose of this study was to develop the program for promoting young children's participation rights based on decision-making learning model and analyze its effectiveness. For this purpose, two questions were set and the details of these questions are as follows: [Question 1〕What is the composition of the program for promoting young children's participation rights based on decision-making learning model? [Question 2〕What are the effects of the program for promoting young children's participation rights based on decision-making learning model? The procedure and methods of this study are as follows: To answer the first question, the objective and goals, teaching contents, and teaching-learning methods of the program for promoting young children's participation rights based on decision-making learning model were chosen through literature review regarding young children's participation rights and decision-making learning model as well as through a survey on the requirements for promoting young children's participation rights in professionals and incumbent teachers. On the basis of the chosen objective and goals, teaching contents, and teaching-learning methods, 20-session activity was designed and a method of evaluating the program was developed. The draft program was examined for applicability to early childhood education before the final plan for the program was developed. To answer the second question, the effects of the program for promoting young children's participation rights based on decision-making learning model on young children's participation rights and decision-making ability were analyzed. The 20-session activity was performed in an average of two sessions a week for 12 weeks from November 12, 2018 to February 15, 2019 in the experimental group of 15 five-year-old children at S Nursery and the control group of 15 five-year-old children at N Nursery in G City. The program for promoting young children's participation rights based on decision-making learning model was run in the experimental group and the general Nuri curriculum was performed in the control group. The adaptations of the contents related to children's human rights education in the Young Children's Attitude Regarding Human Rights Inventory developed by Kim, Kim, and Jang (2008) and the Daily Kindergarten Teaching Plan developed by Kim, Park, and Cho (2009) were used to measure young children's participation rights and Park's (2012) Young Children's Decision-Making ability Inventory in three- to five-year-old children was used to measure decision-making ability. With the scores in the pretest of the experimental and control groups as covariates and those in the post-test as dependent variables, ANCOVA was carried out to test the effects of the program for promoting young children's participation rights based on decision-making learning model on young children's participation rights and decision-making ablity. The results of this study can be summarized as follows: First, the objective of the program for promoting young children's participation rights based on decision-making learning model was to allow young children to 'perceive themselves as the subject of their own life, understand the roles as the subject of rights in many different situations, and improve the ability to participate personally in decision-making processes and make a choice and decision' and the specific goals were to 'express their own thinking and feelings clearly and freely,' 'recognize many different problem situations and participate spontaneously in a decision-making process to solve a problem,' and 'realize a life exerting their own right completely in work and activity.' The teaching contents of this program were six provisions related to the participation right in the UN Convention on the Rights of the Child: 'expression of intention,' 'freedom of expression,' 'freedom of thought, conscience, and religion,' 'freedom of gathering,' 'privacy,' and 'information access.' The teaching-learning principles of the program for promoting young children's participation rights based on decision-making learning model were 'spontaneous participation,' 'mutual respect,' 'practice,' and 'rational decision-making.' The teaching-learning of the program was in the cycle of 'motivation' in the 1st phase, 'problem-setting' in the 2nd phase, 'problem-solving' in the 3rd phase, 'alternative-setting' in the 4th phase, 'alternative evaluation' in the 5th phase, 'decision-making' in the 6th phase, and 'presentation and consolidation' in the 7th phase. Teachers' roles were chosen, focusing on an 'empathic supporter,' a 'participation right promotion facilitator,' a 'decision-making facilitator,' and an 'advocate of children's right.' Assessment was developed in such areas as the goals, contents, and methods of the program. Second, as for the effects of the program for promoting young children's participation rights based on decision-making learning model, the children in the experimental group showed statistically significantly better attitude toward their participation rights in general and some of its sub-areas, such as 'expression of intention,' 'freedom of expression,' 'freedom of thought, conscience, and religion,' 'freedom of gathering,' 'privacy,' and 'information access,' than those in the control group. The children in the experimental group were statistically significantly better at decision-making in general and all of its sub-areas, such as 'self-regulation,' 'situation analysis,' 'emotional utilization,' 'problem-coping,' and 'referential communication,' than those in the control group. In conclusion, the program for promoting young children's participation rights based on decision-making learning model contributed to the improvement in young children's participation rights and decision-making ability. These results demonstrate that the program for promoting young children's participation rights based on decision-making learning model can present systematic and specific roles of participating in many different problem situations or decision-making processes for young children and be run as an effective on-site program.

건설산업에 IT(Information Technology)를 접목시킨 BIM(Building Information Modeling) 기술은 건설산업에서 전 생애주기 동안 생성되는 정보와 업무 등을 통합·관리 할 수 있는 기술이다. BIM 기술의 적용은 선진국을 중심으로 적극적으로 이루어지고 있는 상황이다. 다양한 성공 사례를 통해 효과가 입증되었다. 국내에서도 건축분야에 BIM 기술을 도입하여 장기적인 계획을 세워 활용하기 위해 다양한 연구들이 활발히 이루어지고 있다. 그러나, 토목분야의 경우 건축분야와는 달리 작업체계의 차이점으로 인해 BIM기술의 활성화가 이루어지지 않고 있다. 이에, 본 연구는 실무자를 대상으로 토목분야의 BIM 기술 현황과 활성화를 위한 방안을 제시하였다. 토목분야와 건축분야를 비교하여 건설산업의 BIM 적용 현황에 대해 알아보았다. BIM 기술의 실무자 인식 조사 결과 BIM 활성화 저해요인, 단계별 업무에 따른 BIM기술 필요성, BIM기술 적용 시 효과 등과 향후 BIM의 발전 가능성에 대한 질문들은 비슷한 경향을 나타냈다. 그리고 토목분야는 건축분야에 비해 BIM기술의 활용 현황, 기술 교육 정도 등 현재 BIM 기술 활용 및 교육에 대해 낮은 것으로 나타났다. AHP(Analytic Hierarchy Process)분석 시에는 BIM기술의 활성화에 미치는 요인으로 재무적, 운영적, 투자적, 기술적, 제도적인 부문별로 중요도에 따라 순위를 분석한 결과 5가지의 요인 중 기술적인 부문이 가장 중요하게 나타났다. 또한 BIM 활성화를 위한 각 부문의 대안에 대한 가중치의 평균을 통해 중요도 순위를 제시하였다. 본 연구는 BIM기술의 활성화를 위한 각 요인들의 분석된 결과를 기반으로 효율적인 방안을 제시함으로써 향후 토목분야에 BIM 적용 시 기본방향을 제시할 수 있을 것으로 기대한다. Combining construction industry and IT(Information Technology), BIM(Building Information Modeling) is a technology which can consolidate and manage the information and tasks generated during a whole time in construction industry. The application of BIM technology has actively been achieved globally already, and its effects are proved through various successful cases. Domestically, various researchs have actively been carried out in order to utilize the BIM technology for a long-term planning by introducing it to the architectural field. However, unlike in the architectural field, the activation of the BIM technology is not successful in the civil engineering due to the differences in working system. Therefore, in this research, the current state of the BIM technology in the civil engineering field and plan for its activation will be presented for the practicing professionals. First, we found out the application of the BIM technology to the civil engineering field by comparing the civil engineering field and construction industry in analysis. As a result of the perceptual research of the practicing professionals of the technology, the answers to questions about the developmental possibility of the technology are nearly the same in the assumption of debilitative factors of the activation, the need of the technology according to work steps, and its effects. However, the degree in the questions about the current state of the technology in civil engineering field including its present condition and technical training is lower compared to those of the architecture industry. The analysis of AHP(Analytic Hierarchy Process) is carried out according to the degree of importance in financial, operational, investment, technical, and institutional sections as its activating factors. As a result of this, among the five factors, the technical factor marks the highest degree in both the civil engineering field and architecture industry. In addition to this, the rank of importance about each factor in the activation is derived. This research suggests the effective plans based on the results of the factors about the activation of BIM technology, and present fundamental direction in civil engineering field when applying the BIM technology.
