윤숙영,김홍열,--,우태양 한국화훼연구회 2002 화훼연구 Vol.10 No.1

본 연구는 대구광역시에 위치한 <햇빛치매어르신주간보호센터>에 있는 치매노인을 대상으로 꽃장식이 치매노인의 인지기능에 미치는 영향을 알아보고 꽃장식에서 꽃의 색과 크기의 선호도를 조사하기 위해서 치매노인 6명을 대상으로 2002년 2월 14일부터 2002년 5월 9일까지 주 1회씩 총 12회 원예치료 프로그램을 실시하였다. 대상자는 모두 여성이었다. 평가결과는 다음과 같다. MMSE-K 평가결과 대상자 A는 원예치료 실시 전 13점에서 실시 후 18점으로, 대상자 D는 원예치료 실시 전 5점에서 13점으로 유의하게 향상되는 것을 볼 수 있었다. 대상자 B는 7점에서 8점으로, 대상자 E는 3점에서 7점으로 향상되었으나 유의차가 없었다. 대상자 C는 원예치료 실시 전 15점에서 실시 후에는 14점으로 오히려 낮아졌으나 유의차는 없었다. 대상자 F는 인지능력이 없는 대상자로서 실시 전후 큰 변화가 없었다. 꽃의 선호도 조사결과 색은 적색과 황색 그리고 분홍색 순으로 선호하였고 크기는 중간형보다는 크거나 작지만 풍성한 꽃을 선호하였다. 이상의 결과로부터 꽃장식은 치매노인의 인지기능 향상에 효과적이었다. 재료는 매회 달랐지만 작품을 구사하여 다듬고, 자르고, 꽂고 하는 반복적인 활동을 통해 흥미를 유발하여 적극적으로 자신감을 갖게 되었으며, 또한 결과물을 가족들과 함께 공유하게 함으로써 가족관계도 개선되었다. Abstract. This study set out to research preference of flowers, to analyze the impacts of floral decoration on the improvement of recognition ability in the demented old adults in order to develop an more effective horticultural therapy program for the demented old adults. The subjects were made out of the demented old adults who were taken care of at <HABIT Demented Old Adults Day Care Center> located in Icheon-dong, Nam-gu, Daegu Metropolitan City. Total six subjects were included in experiment. They were all female, and their average age was 76. The experiment was conducted once a week from February 14 to May 9, 2002, total in 12 times. The experiment was only focused on floral decorations. The color and size of flowers were considered to decide the subjects preference. The subjects preferred red and yellow flowers. They also liked big flowers or small but opulent ones. As for floral decoration, the material flowers were different each session. But the subjects were aroused into interest via repetitive activities such as designing their works and arranging, cutting, and putting in flowers. Their active and confident attitudes became evident, and their relationships with their family grew better as they shared their works with them.

와전류센서를 이용한 펜슬가공시 볼엔드밀의 가공궤적 해석

윤경석,왕덕현 경남대학교 신소재연구소 1997 論文集 Vol.9 No.-

펜슬가공시 절삭조건을 변화시켰을 경우 발생하는 공구변형 특성을 머시닝센터의 주축부에 설치한 와전류센서로 측정하여 최빈도(median)필터를 거쳐 해석하였다. 펜슬가공중 코너에서 이송속도를 줄이는 것이 공구변형을 감소시키는데 효과적인 것으로 나타났다. 공구변형을 하향절삭에서 절삭력이 작게 작용하기 때문에 상향절삭보다 하향절삭에서 줄일 수 있었으며, 금형제작에서 펜슬가공할 때 하향절삭으로 상방향 경사면가공을 하였을 경우 가장 양호한 가공상태를 얻을 수 있었다. Tool deflection of ball-end mill in pencil cutting for free-form surface according to cutting condition was measured by eddy-current sensor attached to the spindle of machining center, and analyzed by median filter. The best way to minimize the tool deflection in corner when pencil cutting is to decrease feedrate during cutting. Tool deflection was decreased for down-cutting rather than up-cutting due to the smaller cutting force. The method of upward ramp cutting with down-cutting represents the optimum machining strategy for pencil cutting in the die and mould making industry.

As a part of forestry utilization for livestock feed resources the feeding value ague of shrub leaf by growth stage and grazing behabiour of the native cattle at shrubby grassland in function of seasons were investigated and the following results were obtained. 1. The crude protein content of oak leaf declined as the growth stage increased whereas the contents of crude fiber and crude fat showed the opposite tendency. 2. The intake of oak leaf paralleled with the amount given while the intake of the mixed grass leas remarkable increased and the body weight gain was also remarkably increased. 3. The average number of oak leaf intake was 70.5 times for spring, 148.7 for summer, and 395.7 for autumn. 4. The grazing time by the native cattle was decreased in the order of spring, autumn, and summer. As for the grazing behaviour, the intake activity was most active during morning, mid-day and late afternoon or three times a day. 5. The duration of rumination was found to be in the decreasing order or summer, autumn and spring, cattles ruminated more when the grasses were more abundant. 6. As for the inactive period of animal, it was short during spring when the animals spent more time for eating but it was about 5 times longer during both summer and autumn.

The characteristics of these Si-schottky barrier type and Heterojunction type solar cells are as follows; 1. SnO_2/n-Si Heterojunction Solar Cells Fabricated by Spray Pyrolysis Method SnO_2 film were deposited on the (100) or (111) surface of Si single crystal by the spray pyrolysis method. The best SnO_2/n-Si solar cell has a good performance, with an open-circult voltage: Voc.=0.45V, short circuit current: Isc.=35.5㎃, fill factor: FF.=0.64, and conversion efficiency: η=10.2% under 98㎽/㎠ irradiation of AMl. The spray pyrolysis described in this paper is simple and suitable for mass production. One possibility for cost reduction lies in this method of junction fabrication, and the idea of simply deposited SnO_2/n-Si junction is, at first sight, very attractive. Hence the SnO_2/n-Si Solar Cell and the effectiveness of this method may be of great value in some future production of low-cost solar cells. 2. In_2O_3: Sn Heterojunction Solar Cells Fabricated by Spray Pyrolitic Method Highly conductive and transparent thin films of In_2O_3: Sn (ITO) are fabricated by spray pyrolytic method.

These thin films have simple cubic system with lattice constant 10.2Å. In_2O_3: Sn/n-Si heterojunction solar cells are fabricated, depositing In_2O_3: Sn (ITO) thin films on n-Si substrates with orientation(100) and resistively 2-3Ω, ㎝ by spray pyrolitic method. Under AMl sunlight simulator, the parameters of the excellent cell obtained has open-circuit voltage Voc=0.52V, short-circuit current I_sc=39.0㎃, fill factor: F.F=0.60 and conversion efficiencyη=12.1%. 3. Al/p-Si MOS Solar Cells Fabricated by Vacuum Evaporation Method Al/p-Si MOS solar cells, consisting of Al on P-tupe silicon with a thin interfacial layer of SiO_2 have been found to have good light conversion efficiency for solar radiation. The effects of the oxide layer thickness between metal and substrate were investigated.

쑥 분말 사료를 암돼지 및 거세돈에 첨가하여 그 수준에 따라 0%(T1, 암돼지, T2; 거세돈)와 1.5%(T3; 암돼지, T4, 거세돈)로 각 구별 45두씩 배치, 42일간 급여하여 생산된 돈육의 육질특성은 다음과 같다. 도체중량과 등지방두께는 73가 가장 낮았으며, 도체등급에서는 처리구간 유의차가 없었다(P>0.05). 쑥 분말 급여시 암돼지간(T1과 T3)에서는 조회분, 거세돈간(T2와 T4)에는 조지방 및 조회분 함량이 유의적으로 증가하였다(P<0.05). pH는 저장기간에 증가함에 따라 모든 처리구에서 감소하였으며, 쑥 분말 급여 처리구(T3와 T4)에서다소 높은 pH값을 나타내었다 드립감량은 처리구간에 일정한㎏/㎠경향을 나타내지 않았지만 저장기간이 경과함에 따라 높아졌다. 전단가(shear force, ㎏/㎠)는 T1을 제외한 모든 처리구에서 저장기간이 길어짐에 따라 감소하였다. 명도와 적색도는T3가 T1 보다 다소 높은 수치를 보였으나, 거세돈간(T2와 T4)에서는 오히려 낫게 나타났다. 저장기간이 증가함에 따라 TBARS와 VBN값은 공히 유의적으로 증가하였으며(P<0.05),쑥 분말 급여 처리구(T3 및 T4)에서 유의적으로 더 높게 나타났다(P<0.05). 지방산 분석결과, 포화지방산(saturated fatty acids)은 대조구에 비해 쑥 분말 첨가수준 증가에 따라 포화지방산은 높아지고 상대적으로 불포화지방산(unsaturated fatty acids)은 낮아지는 경향이 있었으나 유의차는 없고, 콜레스테롤의 경우에도 동일하게 유의적인 차이가 없었다. 전체적인 기호도는 신선육 및 조리육 공히 처리구가 낮은 점수를 얻었다. 향후 쑥 분말 급여에 대한 보다 많은 연구가 진행되어야 할 것으로 판단된다. This study was carried out to investigate the feeding effects of mugwort powder on meat quality characteristics for 42 days. The results obtained were as follows; Carcass weight(㎏) and backfat thickness(㎜) of T3 showed the lowest compared with other treatments. Grade scores were not significantly differ among the all treatments. In the proximate composition, crude ash content was higher(P<0.05) in the T3 than that of T1, while, crude fat and crude ash contents in T4 were higher(P<0.05) than those of T2. pH values were tended to low as storage period extended, in particular, those values slightly higher in the T3 and T4. Drip loss(%) was tended to increase during storage. Shear force(㎏/㎠) in all samples showed the decreased during the storage, except for Ti. L^(*) and a^(*) of T3 were slightly higher than those of T1, while, T4 was lower than T3. TBARS and VBN of all samples were significantly increased(P<0.05) as storage period extended, those values significantly higher(P<0.05) in the T3 and T4. There were no differences in saturated fatty acids, unsaturated fatty acids and cholesterol of pork meat between control(T1 and T2) and treatments(T3 and T4). The sensory score of pork samples fed with mugwort power were lower than that of control(T1 and T2) in both fresh and cooked meat. Further studied are needs on the pigs fed with mugwort powder.
