  • Environmental design pattern of the nine Small Urban Spaces at C.B.D. in City of Seoul are surveyed and analyzed for user's satisfaction and behavior under the environmental design evaluation by using Chrisopher Alexander's Pattern Language. Small Urban Spaces as a part of streetscape are formed by physical factors as well as visual environment and interacting user's behavior. Therefore, user's satisfacuion and behavior at the nine Urban Small Spaces were investigated under the further search for some possibilities of a pplication of those Pattern Languages. A pattern language has a structure of a network. It is used in sequence, going through the patterns, moving always from large patterns to smaller, always from the ones which create comes simply from the obsernation that most of the wonderful places of the city were not made by architects but by the people. It defines the limited number of arrangements of spaces that make sense in any given culture. And it actually gives us the power to generate these coherent arrangement of space. As a results, 'Plazl', 'Seats' and 'Accessibility' related design patterns are highly evaluated by Pattern Frequency, Pattern Interaction and their Composition ranks, thus reconfirm Whyte's Praise of urban Small Spaces in our inner city design environments. According to the multiple regression analysis of user's evaluation, the environmental functins related to the satisfaction were 'Plaza', 'Accessibility' and 'Paving'. According to the free response, user's prefer such visually pleasing environmental design object as 'Waterscape' and 'Setting'. In addition to, the basic needs in Urban Small Spaces are amenity facilities as bench, drinking water and shade for rest.

  • This study investigated the ecology and growth of Monostroma nitidum Wittrock in both its natural habitat and the laboratory. The maximum length, width, and weight of M. nitidum in March were 9.0$\pm$4.7 cm, 9.6$\pm$3.6 cm, and 1.52$\pm$1.13 g, respectively. Yellowish-green or yellowish-brown reproductive thalli began to appear in January, and over 80% of the thalli matured by March. The male and female spores were ca. 6 $\mu$m long, and elongate and ovoid in shape. The spores had two flagella and one-eye spot, and tended to swim toward light. Maximum number of spores released from matured thalli was 236 cells/mL after 70 minutes at a light intensity of 100 $\mu$mol/m$^2$/s. The zygote diameter ranged from 3.4-6.0 $\mu$m (mean 4.2 $$m) and increased to 69.8 $\mu$m 14 weeks after culture. The mass release of zoospores was observed from thalli in the dark (3 to 12 days), after 30 min under dry conditions in the shade, at 25$^{\circ}C$, and a light intensity of 100 $\mu$mol/m$^2$/s. The maximum number of zoospores released was 109.8 cells/mL after 60 min of induction. M. nitidum fronds on the net increased to 6.8-7.2 cm in length, and 6.6-8.9 cm in width during the winter.

  • Now many sustitution and false articles is used in korea instead of chenpi. To use chenpi correctly, we will make a quilitative certificational plan of chenpi to investigate all of lieraturea, records and documents. And we could reach conclusions as folloews. 1) Source In china source of Chen-pi is pericarp of citrus reticula Blanco(Family;rutaceae)and in korea source of Chen-pi is pericarp of citrus unshiu Markovich(Family;rutaceae). Though source of both countries are not same, it has no problems because of containing family plants and culture variants. 2) Harvesting and processing After the peel attained full growth, wash cleanly in water. And dry in shade or in low temporature at state of eliminating pericarp. 3) Quality (1) Functional standards Exocarp is soft and clear yellow with numerous oil sports. The less white mesocarp is the better. (2) Physicochemical standards We need to suggest new standards about hesperidin to various conditions by processing methods and storing time. The loss on drying is less than 13.5%. Ash content is less than 4.0%. A standard capacity of hesperidin is more than 4.0%. The content of heavy metal is less than 30 ppm. We can not detect reminding agricultural medicines.

  • Physiological response of Panax ginseng var. atropurpureacaulo (purple stem variety, Pg) to light was reviewed through old literatures and recent experiments. Canopy structure, growth, pigment, leaf anatomy, disease occurence, transpiration, photosynthesis (PS), leaf saponin, photoperiodism and nutrient uptake were concerned. P. ginseng var. xanthocarpus (yellow berry variety, Px) and Panax quinquefolius(Pq) were compared with Pg if possible. Compensation point(Cp) increased with increase of light and ranged from 110 to 150 at $20^{\circ}C$ but from 140 to 220 at $30^{\circ}C$ with 4 to 15 Klux indicating occurence of light and temperature-dependent high photorespiration. Characteristics of Korea ginseng to hate high temperature was well accordance with an observation 2000 years ago. Korea ginseng showed lower Cp and appeared to be more tolerant to high light intensity and temperature than American sheng although the latter showed greater PS, stomata frequency and conductance, chlorophyll and carotenoids. Px showed lower PS than Pg probably due to higher Cp. Total leaf saponin was higher in leaves grown under high light. Ratio or diol saponin and triol saponin(PT/PD) decreased with increase of light intensity during growing mainly due to decrease of ginsenoside $Rg_1$ but increase of ginsenoside Rd. Leaves of Pg and Px had $Rg_1$ but no $Rb_3$ which was only found as much as $20\%$ of total in Pq leaves, and decreased with increase of light intensity. Re increased in Pg and Px but decreased in Pq with increase of light. PT/PD in leaf ranged 1.0-1.5 in Pg and Px but around 0.5 in Pq. Korea ginseng has Yang characteristics(tolerant to high light and temperature), cultured under Eum(shade) condition and long been used for Yang efficacy (to build up energy) while Pq was quite contrary. Traditional low light $intensity(3-8\%)$ for Korea ginseng culture appeared to be strongly related to historical unique quality. Effect of light quality and photoperiodism was not well known. Experiences are long but scientific knowledge is short for production and quality assessment of ginseng. Recent scientific knowledge of ginseng should learn wisdom from old experiences.

  • The effect of varied light intensities on the growth of daughter plants during propagation and after transplant to raised beds were examined in 'Sulhyang' strawberry. To this end, four treatments in controlling solar radiation inside a plastic house were made: 55% retractable shading and 35, 55, and 75% fixed shading. The plastic house was shaded only from 11:00 to 16:00 in June and 10:00 to 16:00 in July to September for the treatment of 55% retractable shading. The mean solar radiation inside the plastic house in the retractable 55% shading treatment was 317 W·m-2 and those in the 35, 55, and 75% fixed shading treatments were 183, 165, and 116 W·m-2, respectively, at 10 o'clock in the morning. The 55% and 75% fixed shading resulted in taller daughter plants with wider leaf areas than 55% retractable shading. The retractable shading also showed higher leaf numbers, crown diameters, root weights, and fresh weights compared to fixed shading treatments. Regarding the inorganic element contents, daughter plants grown under 75% fixed shading had 1.35% total nitrogen content followed by 1.19% in 35% fixed shading, 1.14% in 55% fixed shading, 1.14% in open culture, and 1.10% in 55% fixed shading. After 54 days following the transplant of daughter plants to a raised bed, the fresh weight of the aboveground part was the heaviest in the 55% retractable shading and non-shading treatments. The 75% fixed shading treatment had the lowest fresh weight of the aboveground plant parts. The results of this study could be used for the production of high-quality daughter strawberry plants.

  • Rhododendron mucronulatum for. albiflorum, native species is a shrub that has white flowers on May to June, and rare species endangered by people's rash digging or cutting. But its physiological ecological characteristics and propagation method are not being known at all. Therefore, this study was executed to utilize this species as the planting material for landscaping by analysing its habitat environment and growth form, and also experimenting its seed and vegetative propagation, and it field culture and utilization. The results are as follows; 1. The elevation, gradient and direction of this species were 295-1,350m, 10-36$^{\circ}$, northwest respectively. It was found that the species is shade-liking plant that grows under forest cover of average 51.33%. 2. The soil pH and water content of its habitat were 5.4, 25.41% respectively. The organic matter content was 6.29% that was higher than 3.2%, the average organic matter content of forest soil in Korea. 3. Representative plant community within which this species was living was Quercus mongolica community, and its main neighboring species were Lindea obtusiloba, Fraxinus sieboldiana, Rhus trichocarpa, Rhododendron Schlippenbachii, Rododendron mucronulatum. 4. The leaf length and width of this species were 39.18mm, 12.60mm respectively. This result showed that generally its leaf size was larger than that of R. micranthum, R. yedoense var. poukhanense and R. mucronulatum var. ciliatum and smaller than that of R. mucronulatum and R. schlippenbachii. 5. The whole size of its pollen was, as 59${\times}$61$\mu\textrm{m}$, the largest of plants of Rhododendron family including R. mucronulatum and R. mucronulatum var. ciliatum. 6. The result of seed germination experiment at intervals of 5$^{\circ}C$ from 15$^{\circ}C$ to 30$^{\circ}C$ presented the highest germination rate of 94.7% at 20$^{\circ}C$ numerically, but high percent germination at all temperature levels without significant difference. And the seed of this plant proved to be sun-liking seed at requiring dormancy in germination. 7. Through seed germination experiment by treatment of growth regulators such as GA. Thiourea and Kinetin under dark condition, it was found that the effect of GA treatment on germination increase and acceleration was the highest. 8. In greenwood cutting, rooted rate by treatment of various concentration of IBA and NAA on clay and vermiculite bed was not wholly high, but 100ppm plots of both IBA and NAA of clay bed showed relatively good rooted rate. 9. As result of field culture experiment for finding out optimum growth temperature and light intensity, growth conditions such as height, number of leaves, fresh weight and chlorophyll contents were the best at night/day temperature of 20/25$^{\circ}C$ and under 1/2sun. Also, the photosynthetic rate was the highest at 25$^{\circ}C$. Accordingly, it was found that optimum temperature and light intensity for growth of this plant are 25$^{\circ}C$ (day temperature), 50% of natural light respectively.

  • 수직정원은 식물이 생육하는데 있어 여러 가지 제한이 있는 환경이다. 특히, 기반의 상부와 하부에는 불균형한 수분분포가 나타나는 특징이 있다. 그리고 조명의 설치위치에 따라 다를 수 있지만, 일반적으로 기반의 하부에는 그늘이 발생하여 식물이 생육하기에는 절절하지 않다. 본연구에서는 Felt를 기반으로 하는 수직정원의 위치(상부, 하부 등)에 따른 물리적 특성(함수율, 조도 등)을 실증실험을 통하여 파악하고, 식재가반의 위치적 특성을 분류한 후, 기반의 위치적 특성에 맞는 관수량과 관수주기, 조명설치 방법을 제안하는 것을 목적으로 하였다. 그 결과, 수직정원용으로는 4mm의 기반을 사용하고, 6시간에 한번 약 10분간의 관수를 하는 것이 가장 적절한 것으로 파악되었다. 그리고 식물이 충분히 생육하기 위한 빛 조건을 조성하기 위해서는 기반의 상부와 하부에 보광등을 설치하여야 하는 것으로 나타났다. 관수실험, 조명실험을 실시한 결과, 기반의 상부는 하부에 비해 함수율이 낮고, 빛이 강한 것이 일반적인 결과이고, 하부는 상부에 비해 함수율이 높고, 빛이 약한 것으로 나타났으므로 수직정원에 도입하는 식물을 선정할 때에는 상기의 결과를 참고할 필요가 있다. 향후에는 본 연구에서 밝혀진 기반의 특성을 활용한 식재실험을 실시함으로써, 보다 정확한 식물의 선정과 유지관리 방법을 제시하고자 한다.

  • 사람 사이에 생각을 전달하고 의견을 공유하는 가장 기본적인 방법 중 하나는 이야기이다. 인간은 이야기를 통해 세계를 경험하고 자신의 생각과 경험을 표현한다. 스토리텔링은 이야기 혹은 이야기하기를 의미하는데, 사건, 인물과 배경이라는 구성 요소를 가지고 시작과 끝이 있으며, 시간적 공간적으로 연결되어 표현된 서사를 의미한다. 이러한 스토리텔링에서 스토리는 문화와 역사를 전달하는 수단인데 문자를 비롯한 다양한 매체의 발달에 힘입어 다양한 방식으로 전달 교환된다. 최근에는 컴퓨터들 비롯한 다양한 디지털 매제의 발달로 스토리텔링 방식도 변화하고 있는데, 이를 디지털 스토리텔링이라고 한다. 디지털 스토리텔링은 디디털 매체인 디지털 영상, 텍스트, 음성, 사운드, 음악, 비디오, 애니메이션을 통해 서로 의미를 공유하는 과정이다. 이 스토리텔링은 교육의 영역에서 가장 기본적으로 활용되어 온 방식이다. 즉 교사는 자신의 생각을 학생들에게 전달할 때 스토리를 활용하고 학생들은 스토리를 통해 의미의 형성과 언어의 역할을 이해하며, 의미 있는 사건들 속에서 중요한 요소들을 재조직한다. 그러나 교육의 현장에서 교사는 일방적으로 이야기를 하는 사람, 학생은 수동적으로 듣는 사람이 되어 의미 있는 상호작용이 활발하게 일어나지 못하여 학생들의 실천적 능력을 향상시키지 못하는 한계가 있다. 그런데 가정과 교육은 실천적 지식의 확대와 삶의 총체성의 맥락 인에서 지식을 통합하며 실천적인 행위 속에 수행할 수 있는 능력으로 드러나는 절차적 지식을 목표로 하고 있다. 따라서 이 연구에서는 학습자의 적극적인 참여와 그로 인한 학습 과정 및 결과에 대한 학습자의 자신감과 책임감을 증진할 수 있는 가정교과에서의 스토리텔링을 활용한 수업 설계 방안을 제시하였다. 이 수업 모형은 고정되고 확정된 교수-학습 틀이 아니며 이를 토대로 더 효과적인 수업 모형을 위한 기초석이 될 젓이다. 따라서 후속 연구에서는 다양한 스토리텔링을 적용한 교육과정 개발과 수업 방법이 개발되어야 할 것이다.
