The purpose of this study is to investigate the similarities and differences of disability contents in elementary school social studies and moral textbooks of 2007․2009 revised curriculum. Specific research problems are as follows. First, what are the similarities and differences between the frequency of disability-related content in the 2007․2009 revised textbooks of elementary schools? Second, what are the similarities and differences between the types of disabilities shown in the 2007․2009 revised textbooks of elementary schools? Third, what are the similarities and differences between the disabled and the disabled in the textbooks of the 2007 revised and 2009 revised elementary schools? Fourth, what are the similarities and differences in the types of presentation of learning contents related to the disability understanding education presented in the 2007․2009 revised textbooks of elementary school? The subjects of this study are 37books of social studies and moral textbooks applied in 2007․2009 revision curriculum. Based on the results of analyzing the artwork, photographs, disability - related illustrations and language data in textbooks, the conclusions are as follows. First, the frequency of disability-related contents in the 2007․2009 revised elementary school social studies and moral textbooks is not much different, but the frequency of 'human rights' related exposures in the revised textbooks in 2009 is considerable part of the revised textbooks. It is easy to teach contents. Secondly, there are only five types of disabilities that are common in the 2007․2009 revised elementary school social studies and moral textbooks: vision, hearing, delay, health, and other disabilities. In fact, intellectual disability, which is the most common type of special education students in the community, appears only twice (2.5%) in the 2009 revised elementary school moral textbooks. Third, although the content of disability-related contents as a beneficiary still occupies much in social studies and moral textbooks of 2009 revised elementary school, the figure of people with disabilities as citizens or neighbors who make a community life together with people with disabilities than 2007 revision, It is analyzed that it has improved positively in education. Fourth, there is no difference in the type of disability understanding learning presented in the 2007․2009 revised elementary school social studies and moral textbooks. However, unlike the 2007 revised elementary school moral textbooks, 2009 revised elementary school moral textbooks did not show any role play. In order to correct the problems revealed in the study, the revised curriculum textbook of 2015 should deal more with disability - related illustrations and language data in order to instill proper awareness and attitude toward disability. In addition, various types of disabilities that can be actually encountered in the education field are described and should be used as basic data for understanding the disability. Key-words : contents related to disabilities, view of disabled person

申命記 歷史의 다윗

박기영 연세대학교 연합신학대학원 2000 국내석사

This thesis is an attempt to rediscover the Anti-Davidic descriptions in the Deuteronomistic history and its own Kerygma. That is, to reveal how and why the Deuteronomistic historians had described or compiled(621/ 550 BC) the Anti-Davidic & David dynastic descriptions as the most prominent characteristics in the Deuteronomistic history as compared with the Chronicler's history in relation to the fall of the Israelites and the historical context of the community of the Israelites. The Old Testament (□) is the collection of theological constitutive documents of the progression of Israel's faith (□) in YHWH which spanned more than a millenium. It is also that which had historical meaning to the nation of Israel. Therefore, an account of the history of Israel has a special teaching, that is, Kerygma, which is a significant is sue to explore and seize in history. A definition of the Kerygma in the history of Israel should never exclude the Deuteronomistic history in conjunction with the Anti-Davidic & David dynastic descriptions. The Deuteronomistic history had been written by the theological viewpoint of YHWH's will and His reign which is theocracy. It is the same opinions used by biblical scholars for a hypothetical work composed in ANE times that consisted of the book of Deuteronomy and a variant form of the Deuteronomistic history. The Deuteronomistic historians compiled already existing traditions with the covenants (□) of YHWH and supplied their own theological framework in order to shape the materials into a specific paradigm(e.g., Exod. 20; Deut. 5-z6;8;28;31; Josh. 24; Judg. 8; I Sam. 8;12;15;16; Jer. 2:13). The Anti-Davidic descriptions in the Deuteronomistic history have the purpose of showing the exiles that their situation was the result of infidelity to the covenant of YHWH as set forth in the Torah (□). Here there is a wide difference between the Deuteronomistic history and the Chronicler's history. Each history views the accounts of David from different angles. These“angles”are different theological paradigms. The Deuteronomistic historians reannounce to their community YHWH's Torah and theocratic reign which YHWH instituted in order to conquer all difficulties Israel community has, also Israel's enemies and secure their place. The community of Israel is confronted with their fall. There are no hope, no future, and anyother expectation. Martin Noth asserts that undoubtedly. But, the Deuteronomistic historians have to present a new covenant of YHWH to give a new hope and future by the Anti-Davidic voice. Therefore, the Anti-Davidic description in the DtrH is not a negative voice, but rather has a strongly affirmative tone. It can be described, then, as a paradoxical Kerygma. The Deuteronomistic historians let Israel see that “restoration”and“hope” come only from YHWH's reign (□), covenant and forgiveness as expressed through their own history which contains the Anti-Davidic descriptions. Through these Anti-Davidic descriptions the Deuteronomistic historians expose the hope of the history of Israel and YHWH's unfailing deliverance. Two important theological focuses are found inductively : 1. Disobedience of YHWH and His covenant causes judgement. 2. The Gospel of the Davidic covenant is YHWH's forgiveness, the fulfillment of the salvation of Israel, and eternal hope. In this connection, David's problems and crimes, the Anti-Davidic accounts that come to conclusions of obedience and repentance(□) to YHWH, are the most important theological focuses that the Deuteronomistic historians tried to show with their history. The Deuteronomistic history's ground of interpretation and historical focus is Israel's faith and existence as the holy people of YHWH(Deut. 7:6;14:2)□, who has entrusted Torah to them as evidence of the covenant made with him. The Anti-Davidic aspect is recorded as a historical teaching model that breaks off the covenant between YHWH and Israel. So it is clear that there is no future or hope for Israel separate from YHWH who acts in history. There is no other way for Israel to live, get forgiveness, or salvation from YHWH except by repentance. Consequently, the Deuteronomistic historians’historical mission is projected on the Anti-Davidic record in the Deuteronomistic history. It is to present a renewed covenant that corresponds to YHWH's covenant. Finally, David in the Deuteronomistic history is regarded in the same light as the contemporary Israelites who were to receive this history. It shows the necessity and probability that Israel is judged because it refused YHWH's covenant, reign, salvation, and love. It has a great Kerygma based on confidence and emphasis of YHWH's renewed covenant and YHWH's perpetual reign which shows historical hope through YHWH's love to the holy people. Deuteronomistic theology's merit and limit is focused on Israel as YHWH's holy people and YHWH as the master of the history of Israel. To mirror this requires obedience to Torah and complete faith in YHWH as the Deuteronomistic historians proclaim a reality of an eternal hope for the kingdom of God(□). These are left to us if we recognize the Anti-Davidic descriptions in the Deuteronomistic history.

Claude Achille Debussy의 <Douze Études>에 관한 분석 연구

박기영 신라대학교 일반대학원 2022 국내석사

피아노 연습곡(Étude)은 피아노 연주법의 습득과 연주 기교를 증진시키기 위해 작곡된 곡으로 19세기 초 피아노의 발달과 함께 연주 기교의 습득을 위한 단순한 연습곡에서부터 쇼팽, 리스트 등의 화려한 기교와 높은 예술성을 가진 연습곡들까지 많은 발전을 거듭하였다. 드뷔시(Claude Achille Debussy, 1862~1918)는 19세기 말에서 20세기 초 인상주의 음악을 확립하고 발전시켜 낭만주의 음악과 20세기 현대음악의 가교적인 역할을 한 프랑스의 대표적인 작곡가이자 피아니스트이다. 그는 당시 프랑스에서 유행하던 인상주의 회화와 상징주의 문학의 영향을 받아 독일 중심의 전통적 낭만주의 음악 사조에서 벗어난 독창적이고 새로운 인상주의 음악을 만들었다. 드뷔시는 프랑스적인 간결하고 세련된 음악을 추구하였고 그의 음악 세계를 피아노를 통해 구현하고자 하였다. 그는 피아노의 음색, 테크닉, 작곡기법에 있어서 색다른 개념인 색채와 음향의 효과를 탐구하였으며 이러한 드뷔시의 피아노 음악은 20세기 피아노 문헌에서 가장 중요한 작품 중 하나라고 볼 수 있다. 드뷔시는 쇼팽 피아노 연습곡의 형식을 따르면서 그만의 독창적이며 새로운 음악적 기법들을 모두 담고 있는 새로운 개념의 연습곡을 작곡하였다. 드뷔시의 피아노를 위한 <12개의 연습곡(Douze Études)>은 6곡씩 2권으로 나누어져 작곡되었다. 12개의 곡들은 각각 하나의 제목을 가지고 있으며 각 연습곡들은 한가지씩의 기교적인 과제와 음악적 기법을 다루고 있다. 1권의 6곡은 전통적 연습곡의 특징인 손가락 기능 향상을 위한 곡으로 3도, 4도, 6도 등의 음정 관계를 중심으로 작곡되었다. 나머지 2권의 6곡에서는 드뷔시 피아노 음악의 특징인 색채적인 음색과 다양한 음향의 효과를 꾸밈음, 반복음, 아르페지오 등의 보다 세분화된 요소를 통해 실험하고 있다. 드뷔시의 마지막 독주 피아노곡인 <Douze Étude>는 과감하고 혁신적인 그의 작곡기법들을 모두 포함하고 있으며 이 곡에 나와 있는 실험적인 기법들은 20세기 현대음악 작곡가들에게 많은 영향을 주었다. 또한 연습곡의 장르로서 작곡된 <Douze Études>는 드뷔시 피아노 작품을 연주하는데 필요한 다양한 음색, 터치, 페달링 등에 있어 테크닉적인 어려움을 해결하는 데에도 도움을 줄 수 있다. 따라서 <Douze Études>는 드뷔시 피아노 음악과 현대음악 작품을 연주하고자 한다면 반드시 다루어 보아야 할 중요한 작품이다. The piano practice song(Étude) is a song composed to improve piano performance and performance skills, and has developed a lot from simple practice songs to colorful artistry such as Chopin and List along with the development of piano in the early 19th century. Claude Achille Debussy (1862~1918) is a representative French composer and pianist who established and developed impressionist music in the late 19th to early 20th centuries and played a bridging role in romantic music and contem porary music in the 20th century. He created original and new impressionist music that deviated from the traditional German-centered romantic music trend under the influence of impressionist painting and symbolic literature that were popular in France at the time. Debussy pursued French concise and sophisticated music and tried to embody his world of music through piano. He explored the effects of colors and sounds, which are different concepts in piano tone, technique, and composition techniques, and the Debussy’s piano music can be seen as one of the most important works in piano literature in the 20th century. Debussy followed the form of a Chopin piano practice song and composed a new concept of practice song that contained all of his original and new musical techniques. “Douze Études” for Debussy’s piano was composed in two volumes, six songs each. Each of the 12songs has a single title, and each practice song deals with one technical task and musical technique. Six songs in the first volume are songs to improve finger function, which are characteristics of traditional practice songs, and are composed around pitch relationships such as 3 degrees, 4 degrees, and 6 degrees. In the remaining two volumes and six songs, the effects of colorful tones and various sounds, which are characteristics of Debussy piano music, are tested through more subdivided elements such as decorating, repeating, and arpeggio. Debussy’s last solo piano song, “Douze Études”, contains all of his bold and innovative composition techniques, and the experimental techniques in this song have had a great influence on contemporary 20th century music composers. Composed as a genre of practice songs, “Douze Études” can also help solve technical difficulties in various tones, touches, and pedaling necessary to play Debussy piano works. Therefore, “Douze Études” is an important work that must be dealt with if you want to play Debussy piano music and contemporary music.

This study is to improve reasonable consumption as a consumer and interests of the consumers through analyzing the consumer satisfaction degree on product information provided on Internet, and to present basic information to contribute in protecting consumers through preventing harms on them due to insufficient or unnecessary information. The specific subjects of this study are as followings: 1) It is to analyze understanding of consumers on characteristics of information regarding electric home appliances provided on Internet. 2) It is to analyze the degree of consumer satisfaction on information regarding electric home appliances provided on Internet. 3) It is to analyze whether there is any differences in consumer satisfaction on information focusing on electric home appliances provided on Internet depending on demographic variables and information related variables. 4) It is to analyze how the consumer satisfaction on information regarding electric home appliances provided on Internet is influenced depending on relevant variables. 5) It is to present a current point based on the factual analysis, which can be reflected on basic information provided for resonable decision making by the consumers, policy making for consumer protection and information provided for the consumers, and plans designed by companies regarding information provide for the consumers. The subject of this study is adults who have searched information regarding electric home appliances on Internet. To select sample group of the subject through Internet, it was employed P Consulting, a professional Internet research company, and 500 sample questionnaires have been collected through mail on Internet to the consumers aged over 20 among the panel registered as a member. The research methods were used according to the purpose of analysis of each research questions as followings. It used frequency, percentage, mean, standard deviation, etc. to find out demographic variables, information related variables, consumer satisfaction degree, and degree of significance in information provided for the consumers. It used One-way-ANOVA to analyze differences in relevant variables regarding the satisfaction degree on information provided for the consumers and Duncan's Multiple Range Test to analyze differences from the lower groups. It also used multiple regression analysis to analyze influences by the relevant variables regarding the satisfaction degree on information provided for the consumers, and used the variance inflation factor (VIF) for multicollinearity verification among independent variables to perform the multiple regression analysis. The major results of the study are summarized as followings: 1) The degree of understanding characteristics in information focus on electric home appliances provided for the consumers on Internet found to be 'average'. The easiness and utility of information showed the highest degree, but reliability showed the lowest degree. Accordingly, it found that the consumers were able to acquire information regarding electric home appliances on Internet if needed, and believe the information was helpful for purchase a product. 2) For the degree of understanding by contents, understanding product information among other information showed the highest degree, but understanding services showed the lowest degree. 3) In the degree of significancy for information of the electric home appliances, consumers recognized information regarding services most important. But for the degree of satisfaction by contents regarding electric home appliances, it showed the highest degree for information regarding product quality, but showed the lowest degree for information regarding products. 4) In the difference of satisfaction by information contents depending on relevant variables, it found a difference in monthly average income among social and populational variables, and the satisfaction degree of a group ,which the monthly average incomes of the members is over 4 million won, showed lower degree of satisfaction than other groups. For information related variables, it found the similar degree in accuracy, variability, utility, up-to-dateness, reliability, and easiness, and the satisfaction degree recognized by the servant group was lower than the merchant group. Accordingly, it found that each satisfaction degrees recognized by the consumers were different depending on a degree of recognition of information. 5) The overall satisfaction degree on information regarding electric home appliances on Internet was evaluated through giving a weight to the degree of significancy for the products and adding the satisfaction degree by information contents, and it found to be average. For the overall satisfaction degree depending on relevant variables, the information specific variables were all similar for its accuracy, variability, utility, up-to-dateness, and easiness. That is, the satisfaction degree of the servant group was lower than the merchant group for information specific variables. 6) The variables, which influence on the overall satisfaction degree on information regarding electric home appliances on Internet, were accuracy, variability, utility, reliability of information. Therefore, it found that the satisfaction was higher as the consumers recognized the information more accurate and various. Based on the results of the study described above, the recommendations for policy making for the relevant information provided for consumers, developing programs, and designing plans for provision of information to the consumers by a company can be suggested as follows: 1) Reliability showed the lowest score among the degrees of understanding electric home appliances on Internet. Different from the past, the consumers today are able to distinguish between simple advertisements and useful information through consumption practices, various broadcasting media, etc. They are also able to fairly request necessary information. Low reliability for information provided on Internet, called as sea of information, means lack of information required for judging the information objectively, also means that consumers realize the point. Accordingly, companies or sellers need to make continuous efforts to provide useful information for the consumers as well as information, which the consumers are able to judge objectively with trust in the information provided on Internet. 2) Contradictory results are found that the satisfaction degree showed that lowest for information regarding services among information regarding electric home appliances on Internet, while consumers consider information regarding services most important. Accordingly, consumers are more interested in services after purchasing products in addition to the quality and demand more information regarding the matter. Therefore, companies need to provide more thorough after services to induce re-purchase by the consumers in addition to advertising products and satisfy consumers as a information provider. 3) The information provider through Internet needs to consider every aspects as the satisfaction degree depends on level of understanding characteristics of information, such as, accuracy, variability, utility, up-to-dateness, easiness, etc. It is believed that consumers ask for more complete information provided through Internet rather than through other information sources since Internet provides information through the computer. That means, information should be accurate, objective, diversified, helpful in reasonable decision making, furthermore, credible so consumers can trust on. In addition, consumers need to put more efforts in information searching by themselves to properly evaluate and purchase products in the flow of information. The consumer price in the future can be lowered as the expense spent for information search, and it will accordingly influence interests of consumers. Therefore, it will be more important that companies provide more reliable information, and the government plays a role as information provider, while each consumers make active efforts in information searching. 4) The variables, which influence on the satisfaction degree on information provided on Internet, are accuracy, variability, up-to-dateness, reliability, utility of information etc. In reality, companies or sellers are the information providers for the products displayed on Internet. As it is seen on the study, consumers demand more accurate, various, updated, and reliable information so the information can be usefully utilized in their purchasing. Therefore, companies need to provide information which can be actually used for reasonable decision making fist, rather than exaggerative advertising of products. 5) Internet has brought great changes and impacts on the daily life as a consumer as information orientation and technology have developed. In addition, a gap between the rich and the poor for individual information will be increased as a result of various and prompt gathering of information through Internet on daily life in terms of purchase, credit transactions, reservation oriented culture, education, etc. Accordingly, utilization of information by consumers needs to be more activated in the aspect of policy on information provided for consumers. It can be also achieved through presenting compulsory regulations or reasonable standards regarding responsibility on information provided on Internet, maintaining its clarity, etc. 6) The consumers in the information society, who use Internet to utilize great amount of information for their sakes, need to improve proper judgement ability on information so it can be usefully utilized in their consumption. Furthermore, they should put away passive attitude simply receiving information as their needs and actively utilize information through active efforts in obtaining of information or knowledge. Therefore, it is recommended in the educational aspect for the consumers that consumers organizations or government need to put more attention in developing programs regarding information provided for the consumers and providing education programs regarding information orientation as well as Internet so the consumers can become true information consumers, who are properly able to achieve information or demand for in various aspects.

This experiment was conducted to find out the effect of three useful microorganisms, Photosynthetic bacteria, Bacillus subtilis, and Lactobacillus plantarum, on the plant growth and pot plant quality of Cyclamen persicum Mill. 'Tianis' by drenching 7 times at two week intervals of these microorganisms. The results were as follows. 1. Changes in chemical characteristics of pot media K, Ca, Mg, Na, P2O5, and NO3-N contents in pot media of Cyclamen persicum Mill. 'Tianis' were reduced by three microorganisms. This is considered to be the plant's vigorous growth affecting more a mineral uptake from the media at microorganism treatments. Besides, water retention ability in media was also improved. 2. Promotion of growth of cyclamen pot plants Drenching of L. plantarum as a effective microorganism promoted the growth of the above-ground part of cyclamen pot plants by increase in T/R ratio and plant biomass. Meanwhile, B. subtilis treatment was effective to the chlorophyll contents in leaves. The under-ground part of cyclamen pot plants, composed of roots and bulbs, was growing well at both P. bacteria and L. plantarum treatments. Also, the mineral contents of leaves, CaO, MgO and B, were highest at B. subtilis treatment which induced effective uptake of exchangeable cations in media to the plants. This is considered due to the plant's active uptake of various photosynthate and bioactive materials synthesized by a fungus body. 3. Improvement of pot quality of cyclamen pot plants Both of P. bacteria and L. plantarum were effective to the pot plant balance defined by the ratio of plant height to its width and leaf number to its area. The ornamental value of cyclamen pot plants as best at both P. bacteria and B. subtilis treatments with increase of flowers per plant and the volume of flowers to the whole plant. The vivid color of the flowers was found in all microorganism treatments compared to non-treated control, especially highest at P. bacteria treatment. Unlike the vegetables recommended by microorganisms of 2 to 3 mL·L-1, this study showed that the range of 10 to 20 mL·L-1 in microorganisms was optimal for those drenching in media of pot flower plants, Cyclamen persicum Mill. 'Tianis'. In order to apply the above-mentioned microorganisms to flower production, therefore, further more researches of effective microorganisms are needed on diverse ornamental pot plants. 본 연구에서는 유용미생물로 알려진 광합성균(Photosynthetic bacteria), 바실러스균(Bacillus subtilis), 유산균(Lactobacillus plantarum)을 분화용 시클라멘(Cyclamen persicum Mill. 'Tianis')에 2주 간격으로 7회 관주 처리하여 생육 및 분화품질에 미치는 영향을 알아보았다. 그 결과를 요약하면 다음과 같다. 1. 유용미생물 처리에 따른 배양토 화학적 특성 변화 세 가지 유용미생물을 처리한 분화용 시클라멘 배양토에서 K, Ca, Mg, Na, P2O5, NO3-N 함량이 무처리구에 비해 다소 감소하는 경향을 보였다. 이는 식물체 지상부 생육과 밀접한 관계가 있으며, 왕성한 생육으로 무기성분의 흡수가 원활히 이루어진 결과라고 판단된다. 또한 배양토의 보습력이 향상된 것으로 확인되었다. 2. 유용미생물 처리에 따른 시클라멘의 생육촉진 무처리구보다 세 가지 유용미생물 처리구에서 생육촉진 효과가 있었다. 지상부 생육의 경우 다른 처리구보다 유산균 처리구가 T/R률과 엽무게 증가에 도움을 주며, 바실러스균 처리는 엽록소 함량, 꽃을 포함한 식물체 무게 증가에 도움을 줘 지상부 생육이 촉진되었다. 지하부 생육의 경우 광합성균과 유산균 처리가 뿌리와 구근 발달에 도움을 주었다. 이는 균체에 의해 합성된 다양한 광합성물질 및 생리활성 물질을 식물체가 흡수해 생육이 촉진된 것으로 판단된다. 식물체 내 무기성분 변화에서 다른 처리구보다 바실러스균 처리구에서 CaO, MgO, B 함량 증가 효과가 있었다. 이는 배양토 내 유용 무기성분, 즉 치환성 양이온의 흡수가 증가됨에 따른 식물체 전반의 생육이 촉진된 것으로 판단된다. 3. 유용미생물 처리에 따른 시클라멘의 분화품질 향상 무처리구보다 세 가지 유용미생물 처리구에서 분화품질에 효과가 있었다. 다른 처리구보다 광합성균과 유산균 처리가 엽수, 엽 높이, 식물체 폭, 엽면적 증가에 도움을 주었다. 이는 유용미생물 처리가 식물체에 안정적이면서 풍성한 느낌을 주는 것으로 판단된다. 또한 합성균과 바실러스균 처리가 꽃수, 꽃 무게, 식물체 높이 증가에 도움을 주어 관상가치에 효과적이었다. 식물체 화색은 무처리구보다 세가지 유용미생물 처리구에서 진하게 나타났으며, 특히 광합성균 처리구에서 가장 효과적이었다. 일반적으로, 화훼분야에서 유용미생물 처리에 관한 연구가 미흡한 실정으로 채소분야에서 유용미생물의 권장 사용 농도가 2~3mL·L-1인 것과는 달리 본 연구에서는 광합성균, 바실러스균, 유산균의 경우 10~20mL·L-1에서 시클라멘의 생육과 분화품질이 우수하였다. 한편 미생물의 종류와 처리농도에 따라 식물체 생육 및 분화품질 효과가 달라지므로 유용미생물들의 혼용처리도 고려할 필요가 있을 것으로 판단된다.
