알루민산나트륨과 알루민산칼륨 용액에 $CO_2$가스 吹入法에 의해 $NaAlCO_3(OH)_2\;(Dawsonite)와\;KAlCO_3(OH)_2$를 合成하였다. 이 反應은 80 ∼ $90^{\circ}C$에서 $Na_2O/Al_2O_3,\;K_2O/Al_2O_3$의 몰比가 各 各 6∼8, 8∼10인 알루민산알칼리 용액중에 $CO_2$가스를 吹?하여 達成되었다. 알루민산알칼리 용액중에 $HCO_3^-$이 多量 存在하며 알루미나가 平衡固相으로서 Boehmite로 存在할 때 高純度의 Dawsonate와 $KAlCO_3(OH)_2$가 生成된다는 것을 알았다. 이런 條件下에서 合成된 Dawsonite와 $KAlCO_3(OH)_2$의 示性式은 赤外線吸收스펙트럼 分析結果 各各 $NaAlO(OH)HCO_3와\;KAlO(OH)HCO_3$로 나타내는 것이 妥當하다고 생각된다. 또 電子顯微鏡觀察로부터 Dawsonite는 纖維狀結晶, $KAlCO_3(OH)_2$는 針狀結晶으로 되어 있다는 것을 알았다. A method of synthesizing $NaAlCO_3(OH)_2$ (Dawsonite) and $KAlCO_3(OH)_2$, was investigated by blowing $CO_2$ gas into sodium and potassium aluminate solutions. The reactions were accomplished at a temperature of 80 to $90^{\circ}C$, while $CO_2$ gas was blowing into the solutions which the molar ratios of $Na_2O/Al_2O_3,\;and\;K_2O/Al_2O_3$ were 6 to 8 and 8 to 10, respectively. It was observed that highly purified Dawsonite and $KAlCO_3(OH)_2$ are produced when Alumina is present in Boehmite at an equilibrium solid phase with a large amount of $HCO_3^-$ in the solutions. The rational formulas of Dawsonite and $KAlCO_3(OH)_2$synthesized under the conditions should be expressed as $NaAlO(OH)HCO_3\;and\;KAlO(OH)HCO_3$, respectively, by IR analysis. In addition, electron microscopic observation also indicated that Dawsonite in a fibrous crystal and $KAlCO_3(OH)_2$ in a needleshaped crystal.

오픈소스는 소스 코드를 볼 수 있고 수정할 수 있다는 점에서 기존 코드의 버그 수정이나 새로운 아이디어의 추가가 가능하다. 오픈소스는 이를 이용한 상업용 소프트웨어 개발은 물론 교육용으로도 그 활용 범위가 매우 넓다. 교육용 블록 프로그래밍 환경의 하나인 앱인벤터는 앱인벤터 오픈소스를 통해 자체 로컬 서버의 구축은 물론 플랫폼 자체도 수정할 수 있다. 본 논문에서는 앱인벤터 오픈소스를 로컬 서버에 구현한다. 특히 교육기관의 특성을 반영한 로컬 서버 구축을 위해 앱인벤터 오픈소스 플랫폼을 수정하고 그 과정에 대하여 기술한다. 이를 통해 학생들에게 보다 친숙한 교육 환경을 제공할 수 있고 나아가 학생들의 요구를 반영한 나만의 프로그래밍 블록 추가와 같은 능동적인 대처를 통해 교육 만족도도 높일 수 있다. Open source software allows revising and adding a new idea on them as well as debugging themselves. The open source software can be utilized as various educational programs as well as development of a commercial software products using them. MIT App Inventor, one of the block-based visual programming environments for education, supports building a local server and even revision of the platform itself by providing its own source codes. In this paper we implement App Inventor open sources on the local server. Especially we present how to revise and implement a new App Inventor platform reflecting their own requirements in schools or educational institutes and how to build a local server operating the revised App Inventor platform. They can provide more interactive educational environments to students and improve educational satisfaction through the active customizing of the platform itself such as adding new programming block components requested by students.

To develop some plants utilized as honey plants, oil and/or feed resources this survey was carried out concerning the distribution and production and oil content of seed in Evodia danielli Hemsley. Zanthoxylum schinifolium S. et Z, Zanthoxylum piperritum D.C., Laurus obtusiloba Blume, Styrax japonicus Sieb et Zucc., Camellic japonica L. and Torreya nucifera Sieb et Zucc. distributed in Gyeong Nam district. The results obtained were as follows; 1) Vertical and horizontal distributions over the whole country and Gyeong Nam district of the plants utilized as honey plant. oil and feed resources were described in the text. 2) The seed production of Evodia danielli H. averaged 2.4㎏, 4.0㎏, 9.0㎏ and 14.6㎏ per tree in 6∼10 years old, 11∼20 years, 21∼30 years and over 31 years, respectively, Zanthoxylum schinifolium S. et Z., Zanthoxylum piperitum D.C., Laurus obtusiloba Blame and Styrax japonicus Sieb. et Zucc. produced 63.9g of seed per tree in 4 years old, 76.4g in 5 years, 56.7g in 5 years, and 1.0㎏ in 18 years, respectively. 3) The oil content and oil production of seed averaged 39.24% and 29.5% in Evodia danielli H, 28.97% and 23.5% in Zanthoxylum schinifolium S. et Z., 21.22% and 15.5% in Zanthoxylum piperitum D.C., 28.26% and 25.0% in Laurus obtusiloba Blutm, 24.10% and 17.9% in Styrax japonicus Sieb. et Zucc., 37.50% anti 20.9% in Camellia japonica L. and 21.35% and 10.0% in Torreya nucifera Sieb. et Zucc., respectively. 4) The protein content of seed averaged 15.28% in Evodia danielli H. and 19.01% in Styrax japonicus Sieb. et Zucc. respectively. These trees were found to contain higher protein in seed than other trees surveyed. From the. above results it was concluded that Evodia danielli H. had the most yield, oil content and oil production of seed among some plants surveyed.

This experiment was carried out to investigate the effect of the level of nigroten, phosphate and potash on the grass height, yield and chemical composition of Coix lacryma L.. The results obtained were as follows; 1. Grass height was affected only by the nitrogen fertilization both 1st and 2nd cutting state and not affected by the fertilization of phosphate and potash and by the interaction of N, P and K. In the nitrogen fertilization, grass height was significantly (P$lt;0.05) higher in the treatment (201㎝) applied to 20㎏ per 10a than in the treatment (194㎝) applied to 15㎏ per 10a. However, there were no differences between treatment applied to 20㎏ per 10a treatment applied to 25㎏ per 10a. 2. Yield of Coix lacryma L. on the green basis was significantly (P$lt;0.01) increased only by the nitrogen fertilization among N, P and K. Treatments applied to 20㎏ and 15㎏ of nitrogen per 10a produced 7315㎏ ad 6190㎏ of green grass, respectively, and treatment applied to 20㎏ of nitrogen per 10a was significantly (P$lt;0.01) higher in the yield of green brass than the treatment applied to 15㎏ of nitrogen per 10a. However, there were no significant differences between treatment applied to 20㎏ of nitrogen and treatment applied to 20㎏ of nitrogen per 10a. 3. In the chemical composition of Coix lacryma L. dry matter was not affected by the fertilization level of N, P and K. However, content of crude protein was progressively increased by the increase of fertilization level of N, P and K. On the other band, other chemical composition except dry matter and crude protein also were not affected by the fertilization level of N, P and K. 4. According to the results of this experiment, it may be concluded that the moderate level of N, P and K per 10a. was 20㎏, respectively, for the increase of yield and nutritive value of Coix lacryma L.
