This study was intended to investigate the generalized future expectancies for personal life success and failure in a sample of elemantary students and to determine the association between optimism and pessimism and two other variables; self-concept and academic achievement. For this purpose, 418 of 3rd and 6th grade children were measured on their future expectancy and self-concept by two kinds of questionnaires used after Suh Young Sook(1988) and Kim Ki-Jeong(1984) perspectively. Children's academic achievement were measured by class record(transcripts) of children's grade. The results were appeared that children's future expectancies were quite optimistic regardless of their gender and grade. There was strong positive association between optimism and self-concept, while pessimism appeared different association in accordance with the lower domain of the self-concept. Children's pessimism showed a negative association with academic achievement. It was concluded that children has strong optimistic bias about their adult life in future, and it is influenced by the current self-concept and academic achievement.

The purpose of this study is to propose a method for development of Sport for the Disabled in Korea by analyzing the system of the Rehabilitation sport in Germany. Sport for the Disabled in Germany developed from sport for disabled veterans which trace their beginning to the early part of the 20th century. The experience with physical activities for disabled soldiers and the knowledge of their therapeutic value made its biggest impact in W II. At that time people also discovered significant aspects of sport for disabled besides the medical one, such as the psychological and social benefits. 1956 was the sport for disabled recognized as one method of medical rehabilitation with such aspects. In Germany sport for disabied is conducted on four levels with different goals and tasks: 1) Rehabilitation sport 2) Leisure-time sport 3) Performance sport 4) Special school sport. Rehabilitation sport is used at the last phase of medical treatment and plays an important role as a bridge to the leisure-time sport in which one takes part spontaneously. Rehabilitation sport has following specialities: 1) Rehabiltation sport requires medical prescription and supervision. 2) Rehabilitation sport is carried out in a group in a sport club by a special training supervisor. 3) Types of Rehabilitation sport are gymnastics, athietics, swimming and movement games in groups. Sport for disabled in Korea will also develop rapidly, if rehabilitation sport system is realized in Korea by experts' verifying its value in financial support of government organization, rehabiltation-related organizations etc.

花盆의 水分蒸發이 盆植花卉類의 生育에 미치는 影響

徐榮敎 충남대학교 농업과학연구소 1977 農業技術硏究報告 Vol.4 No.2

This study was carried out to obtain the informations about evaporation from pot, soil temperature and soil atmosphere composition in pot, and the effect on the growth of nine ornamental species using seven different containers. The investigated containers were clay pot(CP), clay pot painted in green(CP-P), varnished clay pot (CP-V), polyethylene film inserting in clay pot(CP-PI), clay pot mulched with black polyethylene film (CP-PM), porcelain pot(POP), and plastic pot(PLP). Nine ornamental species were balsam(Impatiens balsamina), chrysanthemum(Chrysanthemum morifolium), cosmos(Cosmos bipinatus), English ivy(Hedera helix), geranium(Pelargonium zonale), kochia(Kochia scoparia var. trichophila), marigold(Tagetes patula), ornamental kale(Brassica oleraceae var. acephala), and salvia (Salvia splendens). The results obtained are summarized as follows: 1. Dry weight of all tested species grown in PLP, POP, CP-P, CP-V and CP-PI was heavier than that of CP. 2. Plant height in nine tested species grown in PLP, POP, CP-P, CP-V, and CP-PI was taller than that of CP. 3. Geranium grown in PLP, POP, CP-P, and CP-V gave more number of leaf than that of CP. 4. The number of flower in balsam grown in PLP, POP, CP-P, CP-V and CP-PI was more than that of CP. The result from marigold was very similar to this tendency. Spike length and floret number in salvia gave the same tendency, but its spike number was not different among containers used. 5. The average diurnal evaporation from PLP and POP was about 43% of that of CP. About two third of total evaporation from CP was through pot wall. 6. The evaporation rate from the slowest to the highest was PLP, POP, CP-P, CP-V, CP-PI, CP-PM and CP. Containers inhibiting evaporation through pot wall hold more soil moisture than CP from one day after water supply. 7. The more evaporative water-loss from containers gave the lower soil temperature. The variation of soil temperature among containers was higher during the day than the night. 8. The O_2 concentration of soil atmosphere in CP was higher than that of nonporous containers, and the difference between them was 0.40-1.12%. The range of the O_2 concentration was 17.95∼19.62%. The CO_2 concentration of soil atmosphere in CP was lower than that of nonporous containers, and its range was 0.59-1.76%. This deviation in soil atmosphere composition did not influenced on the growth of plants. 9. There was a possitive correlation between the amount of soil water and the plant growth. 10. Plant grown on CP gave more total nitrogen content in top growth than that on PLP. C/N ratio was somewhat low in plant on CP. From the above results, O_2 and CO_2 concentration in soil atmosphere did not gave enough deviation to the extent which affect the plant growth. The effect of soil moisture on the plant growth using different containers was the far-most significant factor from this investigation. Therefore, it was obious that the utilization of the nonporous container might save the cost for water supply and reduce the production cost of the pot-grown ornamental plant in Korea eventually.

박윤관,정용구,정흥섭,서중근,이훈갑,주정화,이기찬 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.8

Two modifications of the Masserman method for the measurement of cerebrospinal fluid (CSF) formation have been designed and compared with the Pappenheimer technique, the Masserman method and its old form of modification in animal experiment. Among the theoretical limitations of the Masserman method, resorption of CSF during the period of measurement was taken into account with two modifications of its integration in this study. The first one was calculated by reduced formula for a simple integration and the second one was produced by Simpson's formula of integration. Twenty adult cats were used for the experiment. Mean CSF production rate calculated by the Pappenheimer method, the Masserman method, the modified Masserman method and newly designed two modifications were 0.0207±0.0018㎖/min, 0.0128±0.0031㎖/min, 0.0166±0.0027㎖/min, 0.0183±0.003㎖/min and 0.0197±0.0033㎖/min respectively. When compared with the Pappenheimer method, data obtained from the Masserman method were significantly underestimated(p<0.01). All modifications have well correlated with the Pappenheimer method, and newly modified Masserman methods showed better cerrespondence.

初·中·高 世界地理 單元 分析

朴潤子,徐贊基 慶北大學校 師範大學 地理敎育科 1994 地理敎育 Vol.7 No.-

The important of world regional geography education increases in the new and open g1obalization society. So, this thesis focuses on clarifying the characteristics of the unit structure, learning content and learning materials of world regional geography in the current geography textbooks in elementary and secondary schools. The result of unit analysis of world regional geography in elementary and secondary school suggest that the scope and intensity of geography be expanding and deepending in terms of the system of unit learing content and learning materials in advanced school. This means the systematic development of world regional geography according to levels of school is basically possible. However most textbooks simply show flat array of geographical information, from which we can see that world regional geography education still emphasize the past static encyclopedic facts. And yet, unit development in middle school seems more appropriate for learners. In high school, the most important step on the geography education, the point of issue is that most textbooks are a simple array of regional facts, so they cannot embody the spirit of the curriculum which emphasizes thematic approach in the regional geography learning. For the sake of geography education development in modern information society, the writers of textbook must have a thorough knowledge on curriculum and take careful notice on writing textbook. Moreover high teachers must to understand that the choice of textbook has an important effect on the geography education and need to take prudent attitude in selecting textbook.

두 종류의 Precision Lingual Arch(PLA)로 구치부 교차교합 치료시 발생할 동적인 치아이동 양상의 차이를 Calorific Machine으로 실험한 연구

전윤식,노준,서문석,박인권 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.1

교정치료란 동적인(dynamic) 진료행위 임에도 불구하고 치료를 위해 사용하는 교정장치의 효과를 평가하는데 있어서는 정적인(static)방법이 주로 이용되어 왔다. 대부분의 교정의들은 동일한 치료목표를 위해 여러종류의 장치가 제시될 때 과연 어떠한 장치가 상대적으로 치료결과 및 치료기간 면에서 상대적으로 더 우수한가를 알고 싶어한다. 이에 본 저자들은 구치부 교차교합 해결을 위해 사용하고 있는 PLA중 Burstone식 PLA(single force응용)와 구치직립식 PLA(couple 기전 응용)간의 치아이동 기전과 치아이동 시간의 상대적 차이를 규명하고 얻어진 결과를 임상에 적용하기 위하여 본 교실에서 개발, 제작한 Calorfic machine을 이용하여 실험한 후 정상치와 경사치의 이동양상과 치아이동시간을 계측하여 paired t-test를 한 결과 다음과 같은 결론를 얻었다. 1. 구치직립식 PLA가 Burstone식 PLA보다 경사치의 정출량과 치근의 수평이동량이 더 큰것으로 나타났다(p=0.0000). 2. 구치직립식 PLA 사용시 정상치(upright molar)의 치아이동은 없는 것으로 나타났으나(p=0.3475) Burstone식 PLA는 미미한 양(0.2mm)이지만 있는 것으로 관찰되었다.(p=0.0001). 3. 경사치의 치아이동시간이 Burstone식 PLA의 경우 약 17.8분정도 소요되었으나 구치직립식 PLA는 3.8분으로 나타났다(p=0.0001). Despite orthodontic treatment(tooth moving) is dynamic act, many orthodontists have used mainly static evaluation method for evaluating effectiveness of the orthodontic appliances. They want to find which is better appliance, especially in the treatment results and treatment period, when they chose one appliance from sugessted appliances for obtaining same treatment goal. The author and colleagues invented and manufactured new machine for getting information about the relative effectiveness from many suggested orthodontic appliances and we named it Calorific machine. We used this Calorific machine to find the relative differences about tooth moving mechanism and tooth moving time between the Burstone' s PLA(single force mechanism) and Molar-up's PLA(couple mechanism)for correcting the posterior cross bite. We measured the distance of tooth moving on the occlusal X-ray film and recorded the moving time of the anchored(control elctro-thermal tooth)and lingually tipped lower second molars(experimental electro-thermal tooth)and then processed paired t-est by SAS program. The results were as follows. 1. Molar-up's PLA showed more extrusive and horizontal movement than Burstone's PLA at the lingually tipped molar(p=0.0000). 2. There is no finding of tooth movement by Molar-up's PLA at the uprighted molar(p=0.3475) but Burstone's PLA showed a little change(0.2mm) at the same molar(p=0.0001). 3. Bustone's PLA took 17.8 minutes for tooth moving but Molar-up's PLA took only 3.8 minutes(p=0.0001).
