The social welfare institutions and activities and its service delivery systems have been changed by the many contextual factors. These days, the reform of social welfare organization and the scope of activities is needed due to privatization. The purpose of this study is to search for the desirable pattern in social welfare administration in the presumption that the service deliverly systems of social welfare are closely related to the reform of social welfare. In terms of the result of this study, the desirabl social welfare organization in the future is designed by having the balance system among such principles as selectivism and universalism. In other words, the integration of social welfare organization should be considered in order to meet the expansion and multiplication of the social welfare need.

이용만,안규동,이성수,함정오,김화성,리갑수,이병국 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.2

근접작업이 시력약화의 원인이 될 수 있는가를 알아보기 위하여 전자부품을 제조하는 2개 사업장에서 1991년에서 1993년까지 입사한 근로자들 중에서 근접작업으로 인정되는 마이크로칩을 조립하는 근접작업자 306명을 조사군으로, 대조군은 세탁기 타이머 및 일반 기계기구를 조립하는 작업자 154명, 계 460명을 선정하였다. 이들 대상자는 1991년 입사자는 1993, 1994, 1995년 시력을 조사하였으며, 1992년 입사자는 1993, 1994, 1995년 3년동안 조사를 하였으며, 1993년 입사자는 1994, 1995년 2년간 시력을 조사하였다. 대상자 중에서 입사시 안경을 착용한 근로자는 82명(17.8%)이었다. 따라서 남자 근로자와 안경착용자를 제외한 여성 근로자들 335명만을 추적 조사하여 다음과 같은 결론을 얻었다. 조사군에서 입사시 시력 1.0 이상이었던 근로자의 분포는 취업 1년 후 약 25-35% 정도 감소하였으며, 2년후에는 약 40-60% 정도의 감소를 나타내었고, 3년 후 약 50-65% 정도로 감소하였고 4년후에는 약 65% 이상 감소하였다. 그러나 대조군에서는 1.0 이상의 시력을 보였던 근로자들의 비율이 취업 1년 또는 2년 후 15-30%의 감소를 보이고 있으나 그 이후에는 큰 변동이 없었다. 이들의 시력변화를 근무년수에 따라 알아보기 위하여 조사된 시력을 순위변수로 하여 Kruskall-Wallis 검정을 시행한 결과 조사군, 대조군 모두에서 근속년수에 따른 순위의 합의 평균이 년차적으로 유의하게 감소하였으나, 입사시부터 근속년수에 따른 조사군과 대조군과의 순위합의 평균에 의한 시력차 비교에서 입사시 조사군의 순위합의 평균이 유의하게 높았던 것이 근무기간에 따라 대조군의 평균이 높아지면서 통계적 유의성이 없고 대체적으로 1년 이후부터 변화가 적은 것으로 나타나 근접작업으로 인한 시력약화를 추정할 수 있었다. This study was carried out to investigate that the close distance works were associated with decreased visual acuity. 306 workers were subjects who had been recruited from 1991 to 1993 in two electronic parts manufacturing factories, and 154 workers were controls who had been employed from 1991 to 1993 in launder machine timer and general machine assembly factories. Subjects who had been employed in 1991 and 1992 were follow up from 1993 to 1995, and subjects who had been employed in 1993 were from 1994 to 1995. The male workers as well as glasses wearing workers were excluded. Only 335 female workers were followed up to study the change of visual acuity. The results were as follows; The rate of workers with visual acuity over 1.0 at recruit year in subjects group was decreased about 25-35% after 1 year, 40-60% after 2 years, 50-65% after 3 years, and 65% after 4 years. While, the rate of workers with visual acuity over 1.0 at recruit year in control group was decreased about 15-30% after 1 or 2 years, and there was no more additional visual acuity reduction after then. Kruskall-Wallis test was performed to investigate the change of visual acuity in subject and control group by work duration. The means scores of ranks in both group were significantly decreased by work duration. The mean scores of ranks in subject group at recruit year were significantly higher than those in control group at recruit year, but these differences were disappeared after 1 year work. Therefore, this suggest that close distance workers may be affected their visual acuity.

주영철,임갑준,한상욱,박중수,조영철,김순재 한국농림기상학회 2000 한국농림기상학회지 Vol.2 No.1

The objectives of this study were to investigate weather conditions which induced discolored grains and viviparous germination, and to evaluate yield responses following viviparous germination during mid- and late- ripening stage, the submergence during reproductive growth stage, and lodging in the yellow ripe stage. Weather conditions which caused glume discoloration at heading stage were 21.3-26.4℃ in average temperature, 75.2-98.4% in relative humidity, 19.3 in transpiration coefficient and 10.8-13.8 m/sec. in wind speed. Yield reduction was 26-27% and 10∼17%, respectively, when the glume discoloration rates were 63.2-65.7% and 38.3-45.2%, obviously due to the decrease in percent of fertile grain and ripening ratio. Weather conditions during continuous rain for 7 days were 96% in relative humidity, 18.9℃ in average temperature, 21.9℃ in maximum temperature, and 16.8℃ in minimum temperature, causing the most viviparous germination in Juanbyeo(45.5%), followed by Jinbubyeo(14.5%), Bongkwangbyeo(14.2%), and Obongbyeo(12.6%). Lateral tillers started to occur when the submergence at the depth of 1.5-2 m lasted one day during the reproductive growth stage. The submergence for 2-3 days at 3-4 m of water depth induced 269-571 lateral tillers/㎡, supporting 32-52% of the total yield. The rice yield in the paddy fields which were left under the lodging conditions until harvesting was not different compared to that of the paddy fields which were kept upright by tieing them together after lodging, but perfect grain ratio decreased about 9.1% in the transplanting culture and 12.5% in the direct seeding culture on dry paddy field because of the increase in immature grains.

This study compares the usefulness of remote sensing with that of aerial photography as a main data source for urban land analysis and development planning. The data was collected over inland districts under the administrative control of Mokpo city, but the results of the study are easily generalized. The main environmental factors considered were annual changes in vegetative ground covering, categorized into sectors according to the type of surface soil supporting it. Remote sensing techniques facilitated the collection of large amounts of data over a wide area in a relatively short time. Remote sensing data was also easy to collect repeatedly on an ongoing basis, making it useful as a fundamental data source for town planning and urban land development. On the other hand, aerial photographs offer a superior spatial perspective on urban lands, making them very useful as data for detailed planning in specific areas slated for intensive development.

최종갑,김태효,박영석 慶南大學校 附設 工業技術硏究所 2002 硏究論文集 Vol.20 No.-

본 논문에서는 스테레오 카메라로 입력된 영상을 3차원 모델링과 깊이정보 추출과 계측알고리즘을 제안하였다. 본 알고리즘은 스테레오 카메라에서 얻어진 2개의 영상으로부터 에지검출을 하고, 특이점들을 추출한다, 이로부터 좌·우 영상간의 대응점을 찾아서 정합시킨다. 영상정합시에 발생되는 폐색영역(occlusion region), 윤곽선잡음(boundary noise) 및 모호성(ambiguity)과 같은 오차성분을 제안한 알고리즘으로 오차를 줄일 수 있다. 실험 결과, 물체의 3차원 정합은 안정적인 정합을 보였으나 정밀한 부분은 1.97%이상의 오차가 발생하였고 전체구간에 대해서는 평균 1.308% 오차가 발생하였다. 이는 입력된 영상들에 대한 폐색, 잡음과 같은 오류성분으로 판단된다. 개선 방법으로 더 많은 각도에서 획득한 영상을 이용함으로써 해결할 수 있으리라 판단된다. In this paper, it is intended to be measured by extracting depth data and three-dimensional modeling of objects about images acquired from stereo cameras. In this algorithm, the edge detection is performed from the two images obtained by stereo cameras, then the features in the two images are extracted. The corresponding points are searched and matched from the left and right images. The proposed algorithm can be reduced the error components such as occluded region, boundary noise and ambiguity of the image feature points occurring when the two images are matched each other. In experimental results, 3D matching was stabilized. But, the errors occurred on detail parts by more than 1.97% and entire domain by 1.308% on the average. It determined to be occluded region, noises from camera images. It will be improved as many as images obtained from various angles.

이영근,장화형,한갑진,고동규,이기성 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.4

rDNA의 ITS2(internal transcribed spacer 2)부위에 대한 이온화방사선(gamma-ray)의 영향을 알아보기 위해서 감마선을 조사한 느타리버섯(Pleurotus ostreatus)의 5종의 변이중에서 ITS2의 염기서열을 결정하였다. ITS2의 염기서열은 1 kGy 조사군(PO-5, PO-6, PO-15와 PO-16)에서 변화되지 않았으나, 2kGy 조사군(PO-14)에서는 1개의 염기가 치환되었다. RAPD(ramdomly amplified polymorphic DNA) 양상에 의한 유전유사도의 변화가 다양하였고 섬유소성 고체검정 배지에서도 다양한 생장특성을 나타내었다. 본 연구결과는 ITS염기서열이 이온화 방사선에 의해 선량의존적으로 변화될 수 있음을 시사해 주었다.

이갑용,김하영,송영대 대구효성가톨릭대학교 자연과학연구소 1997 基礎科學硏究論集 Vol.11 No.2

The correlation was investigated between the obseved heat of ligation and calculated bond energy for octahedral Co(Ⅱ) coHplexes by EHMO(Extended H?ckel Molecular Orbital) and ZINDO/1(Zerner's Intermediate Neglecte of Differential Overlap)method. The net charge of Co2+ion of octahedral [ Co(H2O)6-x(NH3)x]2+ complexes( x= 0, 1‥‥6) is decreased with substituting NH3 for H2O molecule. It was found that a good retationship exists between the observed heat of ligation and the calculated quantum chemical quantities, net charge of central atom, enthalpy of formation, and total dissociation energy. From this fact, we can obtain a linear equation ΔHabs = -0.7728qco +1.2917, ΔHabs =0.0085H?+0.5556, ΔHabs = 0.1279Ediss+0.7510,theoretical equation.

협동학습에서 집단 구성 방법이 학습 동기에 미치는 효과

이영준,조갑선 부산교육대학교 교육대학원 2004 논문집 Vol.6 No.-

It is difficult to divide a class into differentiated groups- although teachers should organize students into small groups considering their abilities and differences to operate differentiated curriculum systems. The purpose of this study is to examine the effect of cooperative learning which can influence student's learning motivation affectively through dividing a class into homogeneous and heterogeneous groups by their accomplishment level. For this study, the questions were formulated as follows: First, does a learning method affect on learning motivation? Secondly, does a group organization affect learning motivation in a cooperative learning class? The following two hypotheses were assumed, based on preceding studies of co-operative learning, to solve above questions. <Assumption 1> Cooperative learning groups have higher motivation than controlled groups. <Assumption 2> In Cooperative learning, a homogeneous group has higher motivation than a heterogeneous group in learning ability. To test the above assumptions, 3 classes of fifth grade at one elementary school in Busan were selected, where a controlled group was taught by traditional learning and another two groups were taught by cooperative learning, where each group consisted of homogeneous and heterogeneous groups. Experiment intervention was for 25 lessons on the fifth grade's subject of Society. A STAD(Student Teams Achievement Divisions) model was applied. The same paper was used for prior and posterior tests with the School Learning Motivation Scale, and score differences on a test of learning motivation was verified by T-test. The result is as follows: First, cooperative learning is good to enhance student's learning motivation(p=.009). Second, dividing a class by student's ability level is not meaningful for differences in learning motivation. There is no difference in other motivations, however a heterogeneously consisted group was very effective to enhance essential motivation. (p=.095) These results of the study show that cooperative learning is better to enhance learning motivation than traditional learning and group organization gives students a way to learn as well as opportunities to communicate. Though cooperative learning is not an effect in learning motivation of a homogeneous group and a heterogeneous group, a homogeneous group organization is effective to enhance intrinsic motivation that makes students learn by themselves without external reward. For students' holistic development, teachers could plan and organize groups properly in class considering the objectives, learning environment and students' differences.
