        알로에는 여러 가지 약리성분을 함유하고 있으며 특히 당단백 분획에서 효과적인 항염증 기작을 나타냄이 보고되었다. 이에 알로에로부터 보다 높은 활성의 항알러지 물질을 분리하고 분리된 성분을 이용하여 정보를 얻어 Aloe cDNA library로부터 유전자를 동정해내고, 동정된 유전자를 이용하여 재조합 단백질을 대량생산하고자 실험을 수행하였다. DEAE 이온 교환수지, Phenyl Sepharose 소수성 결합수지, MonoQ 이온 교환수지, Superdex 75 겔 여과수지 등의 일련의 크로마토그래피를 통해 염증 매개체의 분비 억제 효과를 나타내는 단일성분의 Alprogen을 분리했다. 이상의 단계를 거쳐 정제된 Alprogen 은 약 7 KDa로 예측되며 히스타민 분비억제 효과에서의 IC50 값은 2 ug으로 측정되었으며, 아미노 말단 아미노산 서열을 확인하였다. Alprogen이 함유된 NY945은 항원항체반응에 의해 야기된 MAP kinase, Erk, 의 인산화뿐 아니라 PKC activator 인 PMA와 ionophore에 의한 인산화도 저해하며, LAT의 인산화도 저해한다. 또한 Alprogen 단독으로도 MAFA와 gp49B의 activation 을 유도하여 MAFA와 SHP-1, gp49B와 SHP-2의 결합을 야기하고 이로인한 전반적인 dephosphorylation이 야기된다. 이런 일련의 기작들은 Alprogen의 히스타민 분비억제 기작을 잘 설명할 수 있다. 이러한 일련의 정보를 바탕으로 Aloe cDNA library로부터 2개의 유전자를 동정하였다. 또한 동정된단백질정보를 이용하여 재조합단백질을 디자인하여 합성하였고 이들 또한 활성을 가짐을 확인할수 있었다. Aloe vera has been reported to contain many pharmacological activities such as anti-inflammation. I focused to purify the active component expressing anti-allergic property to develop anti-allergic drug. NY945, alprogen containing fraction, inhibits the phosphoryIation of ERK by FcεRI-mediated activation and by PMA/Ionomycin activation, and inhibit negatively the phosphoryIation level of LAT. Alprogen can activate inhibitory receptor such as MAFA and gp49B, and stimulates recruiting SHP-1 to ITIM motif of MAFA and SHP-2 to gp49B. Its activity is related, presumably, with the immediate allergic response of the mast cell to FcεRI cross-linking by alprogen. Alprogen expressing anti-allergic effect has been purified as a single compound from aloe extracts by using a series of column chromatographies such as DEAE Sephacel, Phenyl Sepharose CL-4B, Mono Q anion exchange chromatography, and Superdex 75 Gel filtration chromatography. It’s molecular weight has been determined to be 7 kDa, and It’s IC50 value was approximately 2 ug for anti-histamine release activity. The N-terminal 15 amino acid sequences of alprogen have been determined. Based on this N-terminal amino acid sequences, two putative genes for alprogen have been cloned by using PCR method from cDNA library of Aloe Because of limitation to obtain enough amount of alprogen for the study from aloe, N-terminal region of alprogen was synthesized artificially. This synthetic peptide also showed inhibitory activity of mediator release. The construction of recombinant alprogen was designed to produce and purify considerable amounts of an active-form of alprogen and this recombinant alprogen was made. The purified rAlprogen has effective in histamine-release inhibitory activity compared to the synthetic Alprogen peptide

        The increase of the old people's population which is rapidly increasing is the worldwide trend. The research of it is settled through a lot of researches and experiences in advanced countries, but the measures of the aging are not prepared in developing countries and other countries because of the economic problems. It will be very important that the conditions of the aging in Korea are examined under such a condition. although the domestic researchers have examined it, it, in fact, remains in the level of accommodation or consideration of facilities. Solving the old people's problem should be done by national and social project, but in advanced countries, it seems to be desirable that it is solves at home. Or position in the post-industrialization society results in a great change in the position of old people due to the women's participation in social activities and early retirement. Moreover, it is very obvious that such trend will bring about the domestic problems. This study regards the consideration of old people at home among the various methods and researches of old people as the most important method and makes the residential space for the old people which focuses on the planning and design of urban houses according to the urbanization the theme of the research, Architectural behaviors such new construction of reconstruction have no consideration for the aged and disabled persons. But it is time not to neglect such a consideration for the aged and disabled persons. Therefore, first this study investigates the matters to be checked in designing the urban houses which consider the aged and disabled persons in future with the cses of the literature related because of a difficult sample selection and then plans a concrete stage of the research according to the sample selection for substantial matters. There are of course many problems to be considered such as establishment of a proper standard, consideration of legal regulations, the development of personal security equipment and the necessaries of life for the aged and disabled persons, the education and cultivation of the professionals and the consideration of organic and systematic communication system. Accordingly, this study approached with such a background and necessity investigates the problems for designing the residential space for the aged and disabled persons in urban houses. Chapter 2 deals with the property of users and chapter 3 the consideration and conditions of residential life. In concrete, it examines the detailed space and equipments for the condition, planning and design of comfortable residential life and space. Chapter 4 divides the key points in planning and designing the residential space for the aged and disables persons into three stages. The first is for the construction of space for self-support, the second for enhancing the spatial construction for high frequency residence and the third for classifying the behaviors in facility space in planning and designing the houses. Consequently, it is thought that the living space of the aged in urban district should be considered in equal conditions to the disabled persons in planning and designing it. And it is judged that the planning and design considering variable residential space, structure and equipments which can be changed at any time are required.

        This study was conducted for overturning angle simulation model of the self-propelled pulling-type radish harvester. The load measurement system and a finite element analysis model of the pulling-type harvesting part were developed using simulation software. Simulation results show that the maximum overturning angle of the self-propelled pulling-type radish harvester was 63.3° when the driving direction was 45°, and the minimum overturning angle was 28.6° when the driving direction was 180°. According to the overturning angle testing foundation of agricultural technology commercialization and transfer (FACT), the overturning angle of the self-propelled agricultural machine is safe at more than 30°. The overturning angle was less than 30° at the driving direction between 165° and 195°, and it is considered that improvement of the overturning angle of the self-propelled pulling-type radish harvester is necessary. Therefore, ballast, a method of improving the overturning angle, was applied to the self-propelled pulling-type radish harvester and the overturning angle simulation was performed according to the position and weight. As a result, the simulation results show that when the weights were mounted on the right front of the self-propelled pulling-type radish harvester, the overturning angle exceeded 30° in all driving directions. Analysis results of the load data, the maximum pump input torque during harvesting was 20.38 Nm. As a result of the finite element analysis theoretical method of the pulling-type harvesting part, the maximum deformation was -0.01513 mm and the maximum stress was 18.84 MPa. As a result of the finite element analysis simulation method for pulling-type the harvesting part, the maximum deformation was 0.011716 mm at the top of the driving shaft and the maximum stress was 16.846 MPa at the middle of the driving shaft. As a result of the analysis for the theoretical method and the simulation method, the failure load of the pulling-type harvesting part was 7.14% and the stress was –4.17%. Therefore, it is considered that the overturing angle can be improved by adding a weight on the front right side of the self-propelled pulling-type radish harvester used in this study, and the deformation during the harvesting operation was enough elasticity to resist the deformation.
