The purpose of this study is to develop a plan to improve the status of local autonomous body ordinances applying disability grades according to welfare law for people with disabilities. The results are that First, 215 of the total municipalities applied the disability grade, and 1,071 cases were applied to the disability welfare law. Among them, 60.04% (643 cases) of the ordinance that can be divided into severe (1-3 grade) and mild (4-6 grade) were found, and 39.96% (428 cases). A new service eligibility standard that reflects factors such as the needs of persons with disabilities, social environment, etc. needs to be developed. Second, since the exemption reduction service accounts for more than 40% of all projects, it is necessary to set the standards considering the other standards within the scope of not decreasing the total service amount when revising the ordinance. Based on these results, We will provide important basic data for establishing new service provision criteria to replace the disability level at the local government level.

In this study the natural colorant was extracted from black bean seed coat in aqueous solution and used to dye silk and cotton fabrics. To obtain the optimal dyeing conditions it was examined at various dyeing condition (temperature, pH, time and liquor ratio). The dyeing behavior and the depths of shade which were evaluated in terms of K/S and CIELAB color difference values of the dyed and mordanted fabrics were also investigated. The dyeing fastness evaluated standard light and wash fastness tests. The obtained results were as follows ; The most K/S value of silk and cotton fabrics were obtained when the pH was 4.0 and 4.8, respectively and it increased slightly with dyeing time passes when the dyeing temperatures were at $40^{\circ}C$ and $60^{\circ}C$ but, it increased at $80^{\circ}C$. The color of silk fabrics changed from yellowish red to yellow at only Fe mordanting among various mordanting. Sn and Ti mordanting of silk fabric and only Ni mordanting of cotton fabric increased the $L^*$ values, but the others decreased. The light fastness of silk fabrics showed 4-6 grade without mordant, 4-5 grade with Al, 3-4 grade with Cu and Sn, and 2-3 grade with Fe as mordant, and that of cotton fabrics showed 1-2 grade without mordant, 2-3 grade with Fe, 2 grade with Cu, 1-2 grade with Al and Sn as mordants. All mordanting coluld not improve the light fastness of fabrics. Washing fastness(fade) of silk fabrics showed 2 grade without mordants and 2-3 grade with mordants and those of cotton fabrics showed 4 grade with Cu, 3 grade without mordant and with Al, Sn and Fe. All of the washing fastness(stain) of both fabrics showed 4-5 grade.

본 연구는 한우 근내 지방 축적 기작을 구명하고 고급육과 저급육에서 차등 발현되는 유전자를 발굴 동정하여 한우 육질 진단을 위한 분자 표지 마커로 활용하기 위해 GeneFishing PCR 기법을 이용하여 한우 육질등급에 따른 등심조직에서 차등적으로 발현되는 유전자를 분석하였다. 한우 육질 등급($1^+$ 등급 vs 3 등급)간에 총 10개의 차등 발현 유전자가 확인되었고 이 가운데 고급육 한우 등심에서 발현량이 높은 유전자가 4개 그리고 저급육 등심에서 발현량이 높은 유전자 6개가 각각 검출되었다. 발현량 차이 유전자를 cloning하여 염기서열을 분석하고 상동성 검색을 실시한 결과 고급육에서 발현량이 높은 DEG는 주로 EST(expressed sequence tag) 유전자들로 밝혀졌고 저급육에서 발현량이 높은 DEG는 malate dehydrogenase 2(MDH2), myosin heavy chain 2a, triosephosphate isomerase 1(TPI 1), actin, alpha 1, skeletal muscle(ACTA1 ) 유전자들로 동정 되었다. 본 연구를 통해 한우 육질간 차등 발현되는 유전자들은 한우 육질 및 등급판정을 위한 표지인자(marker)로 활용할 수 있어 유전자 마커를 이용한 고급육 생산 한우의 육질 조기진단이 가능할 것이다.

This study analyzed the vocabulary level in the 'Water' unit of chemistry I textbook. It also analyzed its relevance to the 11th graders' vocabulary level. The main tool for analyzing vocabulary level was SWA(Science Word Analysis) program which was referenced the Standard Korean Dictionary and Graduated Vocabulary of Korean Language Education. The results in this study turned out to be as follows: The distribution of scientific vocabulary level increased from Level-1 to Level-3 and showed a tendency to decrease from Level-3 until Level-5. The average percentage of Out of level is the largest as 37%. The highest percentage of non-scientific vocabulary was Level-1. The distribution of non-scientific vocabulary level decreased progressively. The Level-5 and Out of level are used 18% averagely. So, there are 6 vocabularies of Level-5 and 82 vocabularies of extra-level inappropriate in scientific vocabularies. And there are 53 vocabularies of Level-5 and 145 vocabularies of Out of level inappropriate in non-scientific vocabularies. Therefore, the overall state of textbooks for grade 11 students are reasonable. But there are a great many vocabularies inappropriate for them. Those should be used minimum, and to be changed to the 1-4 of level vocabulary as stated in the student's level of understanding of appropriate vocabulary.

This study aims to develop eco-friendly propellant that reduce the generation of harmful gases such as HCl gas and increase the emmision of nitrogen gas emissions. For this purpose, GUDN(N-Guanylurea dinitramide) and BTATz(3,6-bis(1H-1,2,3,4-tetrazol-5-ylamino)-1,2,4,5-tetrazine), which are low carbon high nitrogen materials, were used instead of AP(Ammonium Perchlorate) and Al(Aluminium), which are gernerally used in solid propellant. The prepared propellants were analyzed for mechanical properties and combustion characteristics, performance and AGARD smoke classification. Compared with AP/Al propellant, GUDN/BTATz propellant tended to decrease mechanical and combustion rate. Also, as a result of the static test after the production of the 4-inch motor, the performance of combustion of the GUDN/BTATz propellant decreased, but it was confirmed that the secondary smoke was improved by reducing harmful gases such as HCl gas.

The fatty acid composition of Hanwoo beef was investigated by different quality grades and cuts. Five cuts (strip loin, loin, chuck roll, top round, brisket) were obtained from 15 Hanwoo beef cattle [bulls and steers, 24-30 mon old]. For each quality grade of $1^{++}$, $1^+$, 1, 2, 3, three animals were selected. The contents of C18:0 in chuck roll, strip loin, brisket, top round and loin were significantly higher in 3 quality grades than those of the other grades respectively (p<0.05). The C18:1n9 content in the chuck roll was not significantly different among the different grades, but those of strip loin, top round, brisket, and loin were significantly higher in $1^{++}$ quality grade than those of 3 quality grade (p<0.05). The C18:3n3 content was significantly higher in brisket of $1^{++}$ quality grade and loin of 3 quality grade than the other grades for the same cut (p<0.05). However, those of strip loin, top round and chuck roll were not significantly different (p>0.05) among the different grades. The C18:3n6 content in chuck roll and loin was significantly higher for 2 quality grade than in those of the other grades (p<0.05). For five cuts, total SFA contents for 3 quality grade were significantly higher than in other cuts. The total MUFA content of $1^{++}$ quality grade was significantly higher than in 3 quality grade (p<0.05). The total n-3 PUFA content was not significantly different in chuck roll, strip loin and top round; however, those of brisket were significantly higher in $1^{++}$ quality grade (0.15%) and those of loin were significantly higher in 3 quality grade than in the other grades (p<0.05). The total n-6 PUFA content was significantly higher in 3 quality grade than in those of the other grades (p<0.05).

To clarify the distribution of vascular plants and their usefulness in Heoninlleung, Ecological Landscape Conservation Areas of Seoul, we investigated it from April, 2006 to June, 2009. Total 313 taxa; 68 families, 191 genera, 264 species, 41 varieties and 8 forma were distributed in Heoninlleung. Among them, 37 taxa were highly abundant everywhere (3A), 16 taxa were highly abundant locally (3B), 70 taxa were moderately abundant everywhere (2A), 96 taxa were common in certain regions locally (2B), 9 taxa were rare but observed everywhere with low frequency (2A) and 85 taxa were rare and observed locally (1B). The economic plants were 293 taxa. There were 156 taxa of edible source, 223 taxa of medicinal source, 141 taxa of ornamental source, 69 taxa of pastoral source, 12 taxa of industrial, and 8 taxa of timber source. Twelve Korean endemic plants were collected. Based on the list of rare plants by the Korea National Arboretum and Ministry of Environment, 2 rare species were found. The specific species of I~V grades by phytogeography were 19 taxa. And twentyfour taxa of naturalized plant species were distributed. Naturalization Index was 7.7% and Urbanization Index was 8.4% in the investigated area.
