The previous study about self-propulsion test with synthetic ice for the Canadian Coast Guard icebreaker should that there were some difference between the tests with a synthetic ice and a refrigerated ice. In the present study, the density of synthetic ice is varied to have more interactive between the hull and ices which might make a more towing force than the previous case. The experimental work with refrigerated ice for the present model ship is expected to be conducted to compare in near future.

개인별 지원계획의 바우처 조정방식에 관한 고찰 : 발달장애인지원법을 중심으로

이승기,김진우 사회복지법제학회 2015 사회복지법제연구 Vol.6 No.-

본 연구는 발달장애인의 권리보장 및 지원에 관한 법률에서 규정하고 있는 개인별지원계획의 변경·수정 사항 중에서, 동 계획에 포함되는 장애인활동지원제도, 발달재활서비스, 장애아가족양육지원서비스 그리고 발달장애인부모심리상담서비스 등 4개 바우처 간에 서비스 양을 상호간 어떻게 이전하고 조정할 것인지에 관해 고찰하는 것이다. 4가지 바우처는 각각의 제공목적에 따라 발달장애인 및 그 가족에게 주어진 기준에 따라 제공되지만, 개별 단위 수준에서의 합리성이 반드시 전체 총합에서의 만족도의 극대화를 가져오지 않을 수 있기 때문에 보다 높은 만족도 수준을 이룰 수 있는 바우처 간 조정방식을 고찰할 필요가 있다. 이를 위해, 본 연구에서는 바우처 수혜 주체의 문제, 적격성의 문제, 조정수준의 문제, 조정시기의 문제, 조정절차의 문제, 조정환원의 문제 및 조정액 부담의 문제 에 대해 검토하고 대안을 논의하였다. 또한, 현재의 발달장애인지원법은 발달장애인의 서비스 지원 방식의 발전뿐만 아니라 전체 장애인복지서비스의 방향을 이용자 중심적으로 전환하는 기반이 될 것이라는 점을 강조하고, 동 법이 실효성 있게 시행되기 위해서 바우처 조정방식에 대해 보다 구체적이고 정교한 설계 및 명문화 작업이 필요함을 제시하였다. The purpose of this article is to explore optimal points through transferring service amount among 4 kinds of vouchers - personal assistance service, rehabilitation service, supporting nurture service and psychological counselling service - provided in the personal support plan, which is included in the Act for rights and support for persons with developmental disabilities. These vouchers are offered by the criteria of their own eligibilities, which does not necessarily means the optimal satisfaction of persons with developmental disabilities in terms of service users. It says that the satisfaction of users may be enhanced when the amount of vouchers is transferred among them according to their needs and situations. In order to do so, this article deals with 7 controversial points: subjects, eligibility, amount, period, process, restoration and charge, and presents that these points will be regulated concretely in the Act to make it more effective and enhance the satisfaction of persons with developmental disabilities as users.

The welded metal bellows is commonly manufactured by welding pairs of washer-shaped discs of thin sheet metal stamped from strip stock in thickness from 0.025 to 0.254 mm. The discs, or diaphragms, are formed with mating circumferential corrugations. In this study, the diaphragms were welded by using a CW Nd: YAG laser to form metal bellows. The bellows was fixed on a jig and compressed axially, while Cu-rings were installed between belows edges for intimate contact of edges. The difference between the inner diameter of bellows and jig shaft causes an eccentricity, while the tolerance between motor shaft and jig shaft causes a wobble type motion. A vision sensor which is based on the optical triangulation was used for seam tracking. An image processing algorithm which can distinguish the image by bellows edge from that by Cu-ring was developed. The geometric relationship which describes the eccentricity and wobble type motion was modeled. The seam tracking using the image processing algorithm and the geometric modeling was performed successfully.

Micro zigzag-type springs have been fabricated and characterized using shape memory alloy wires. Zigzag- type shape memory allloy springs, which are functional material applicable as actuator material, have planar structure. Coil-type springs, however, have three-dimensional structure, so zig zag-type spring has advantages of small dead volume over coil-type spring. The proposed fabrication method of zigzag-type spring is very simple and can be applied for thin-tube type actuator.

We have previously reported that the abstinence syndrom of narcotic addicts was relieved by the protein extracts of animal hard tissue (from Manis pentadactyla). The protein extracts of the hard tissue were found to be a sort of keratin. Keratins were extracted from three species of animal horns (bovine horn, water buffalo horn and rhinoceros horn) with 0.1 M-Thioglycolate at 40℃ and S-carboxymethyl derivatives (SCMK) of the keratin were synthesized by the method of Gillespie and his co-workers. The yields of the keratin derivatives were in the range of 16% to 30% of the dryweight of the horns. In an attempt to elucidate and compare the compositions of the keratin derivatives, the analysis for amino acids, monosaccharides, hexosamines, uronic acids, sialic acids among bovine horn, water buffalo horn, and rhinoceros horn, were performed. Eighteen kinds of amino acids were found in the three keratin derivatives and there were no differences in the composition among them, with the exception of lysine contents of bovine horn protein extracts(2.67%), which was distinctively lower than those of water buffalo horn protein extracts(5.57%) and those of rhinoceros horn protein extracts (4.99%). The amounts of carboxymethyl cysteine of bovine horn are twice of those of water buffalo horn and those of rhinoceros horn. In view of these results, it is presumed that the crosslinking rate of bovine horn keratin by cystine disulfide bridge is higher than those of water buffalo horn and Rhinoceros horn. The conjugated components of the keratin derivatives, such as monosaccharides, sialic acids, hexosamines, and uronic acids were totally contained 1.38% in bovine horn keratin, 0.47% in water buffalo horn keratin and 1.04 in rhinoceros horn keratin. There are some similarities among the keratin derivatives of the three species, such as these keratins do not contain galactosamine but glucosamine, and also the existance of glucuronic acid in these keratins is not detected but galacturonic acid. The sugar moieties of these proteins consisted of glucose, galactose, xylose, fucose in bovine horn protein extracts; glucose, galactose, xylose, fucose in water buffalo horn protein extracts; glucose, galactose, mannose, ribose in rhinoceros horn protein extracts.

탈곡기의 선별 성능을 측정하는 방법의 개발에 관한 연구

이승기,정창주 한국농공학회 1975 한국농공학회논문집 Vol.17 No.1

This study was intended to develop a method for measuring the grain separating performance of threshers. The grain separating apparatus used for the experiment was designed and constructed, the function of which was to separate pneumatically mature and immature grain, chaff, straw, dust, and other impurities from the products of threshing. The apparatus has five material outlets where grains and impurities are fallen down by separation depending upon the specific gravity of the material white it moves above the outlets. The principle of design was to separate the mixture of mature grain, immature grain and chaff as distinct as possible, and to induce the mature grains onto the first outlet, the immature grains onto the second and the third, and the straw wastes onto the forth and the fifth outlets. The developed apparatus was tested to evaluate its separating performance with two rice varieties (Tongil and Mine-hikari) at different moisture levels and air velocities. The optimum conditions for operating the apparatus were found from experiment. The results are summarized as follows; 1. The degrees of separation, especially the amount of immature grain contained in the mature paddy, were dependent upon air speed delivered. The optimum air velocities for this apparatus for each levels of grain moisture contents were found from a series of experiments as follows; 14.7-15.3m/sec. for grain of 16 percent moisture content in wet basis, 15.3-16.0m/sec. for 20 percent, and 16.0-16.4m/sec for 24 percent. 2. Composition ratios determined based on the brine separating method was fairly well acted upon the developed apparatus, indicating its recollecting rate of the mature grains as 97.6 to 99.9 percent. The developed separatus acted similarly upon the two rice varieties which had different composition of immature paddy grain. In other words, the separating performance by the apparatus had a good correlation with the one by the brine separating method. 3. As immature grains were separated out unsatisfactory in these experiments than the brine separating method, further investigation may be needed to improve a separating performance of these materials. But the results obtained suggested a possibility of using the tester to replace the current hand separating method, ther eby enabling more consistent test results and also eliminating nearly all costly hand seperating operations.

동물 경조직 단백에 관한 연구의 일환으로 3종의 동물의 각질(우각, 수우각, 서각)을 각각 채취하여 Gillespie 등의 방법에 의하여 0.1 M-thioglycolate로 $400^{\circ}C$에서 keratin을 추출한 후 S-carboxymethyl (SCMK) 유도체를 합성하였고 $\frac{1}{10}$ N-HCl 로 등전점 (pI 4.7~5.05)의 범위에서 침전된 단백을 각각 분리하였다. 추출된 경단백의 수득량은 건조 중량으로 16~30%이었다. 추출된 keratin의 아미노산 조성은 3종 공히 18종이었으며, 그 조성비의 차이는 별로 없었으나 단 우각에서 추출된 단백질의 Lysine 함량은 2.67%로 수우각 5.57%, 서각 4.99%에 비하여 현저한 차이가 있었으며, 우각의 S-carboxymethyl cysteine의 함량은 9.41%로 수우각 6.06%, 서각 5.96%에 비해 크므로 우각 keratin의 disulfide bridge에 의한 cross-linking 정도가 수우각, 서각에 비해 크다는 것 을 나타내고 있다. 추출 단백의 monosaccharide, sialic acid, hexosamine, 및 uronic acid의 조성을 분석한 결과 이들 총 함량을 표시하면 추출 단백질의 건조중량에 대하여 우각은 1.38%, 수우각 0.47%, 서각 1.04%이었다. Sialic acid의 함량은 추출 단백의 건조중량에 대하여 gm 당 우각 $1.26{\mu}mol$, 수우각 $0.29{\mu}mol$, 서각 $0.96{\mu}mol$로 나타났다. Hexosamine 분석에서 3종 공히 galactosamine은 검출 되지 않고 glucosamine만이 검출?瑛만? 또한 uronic acid 분석결과 glucuronic acid는 3종 공히 검출되지 않았고 galacturonic acid만이 검출되었다. 또한 중성당의 조성은 우각 및 수우각에는 glucose, galactose, xylose, fucose가 서각에는 glucose, mannose, ribose가 각각 검출되었다.

직접지불제도와 개인예산제도 도입을 위한 탐색적 연구 - 영국 사례를 중심으로 -

이승기,이성규 한국장애인복지학회 2014 한국장애인복지학 Vol.- No.26

This article explores possibilities of introduction of direct payments and individual budgets to Korean welfare system for people with disabilities, through a study on experiences of United Kingdom. Though direct payments and individual budgets have differences between origination and objects, they have in common that they tryed to achieve choice and control over services for people with disabilities by offering cash for services. Through analysing the process of setting up of the two systems in U.K. as well as comparisons of U.K. and Korean situation, this article presents agendas and alternatives to introducing to Korean welfare system. It analyses cases of U.K in terms of service providers, and users. Based on this analysis, it discusses necessities of delivery systems for cooperations between service providers and government. In addition, in the light of experiences of U.K, it presents necessities of disability movement, which played key roles in the establishment of direct payment of U.K. 본 연구의 목적은 영국의 직접지불제도와 개인예산제도에 대한 고찰을 통해 우리나라에의 도입가능성을 탐색하는 것이다. 직접지불제도와 개인예산제도는 기원과 대상에서 차이가 있으나, 장애인의 서비스에 대한 선택과 통제를 강화하고자 서비스에 해당하는 비용을 장애인에게 현금으로 직접 지불한다는 측면에서 동일한 방향성을 가지고 있다. 본 연구를 위해 제도도입 과정을 분석할 수 있는 과정연구 방법을 채택하였으며, 특히 이해관계자의 입장을 분석하는 데에 초점을 두었다. 직접지불제도와 개인예산제도가 공급자가 아닌 이용자의 권한을 강화하는 제도라는 점을 중시하여, 이해관계자를 공급자와 이용자로 나누었으며, 공급자는 정부와 서비스제공기관으로, 이용자는 장애인당사자로 설정하였다. 분석 결과 우리나라는 영국과 달리 서비스제공체계에 있어서 정부와 서비스제공기관의 단절적 관계가 뚜렷하여, 이를 극복하기 위한 제도적 장치마련이 선행되어야 하며, 또한 양 제도가 장애계의 지속적인 노력을 통해 제도화되었다는 점에 비추어, 장애인당사자의 인식 공유와 장애운동 차원에서의 접근이 필요함을 제시하였다.
