Place of collection : Mt. Mi-ryong in Gun-san and son-un buddist temple in Ko-chang area, etc. A semi-indeciduous, perennial herb. Fragrant white flowers bloom from June through July, which get yellow gradually. Medicinal use : diuretic, stomachic, antifebrile and pleurisy cure and so on. Ornamental plant : in pots or in a garden. Propagation by ramification and cutting. It is observed that roots come out in june by hydroponic cutting. Interspecific hybridization and ecological species-breeding is needed for developing the horticulture of this herb. 2. Trachelospermum asisticum var. intermedium ?? Place of Collection : Mt. Paek-un in Chon-nam province (Nursery garden of seoul National University). A indeciduous, perennial herb with climbing stem. The leaves are glossy. White flowers, which are changed into yellow later, bloom from May through June. The circular corolla, which looks like a windmill, is so beautiful as to be paid attention to. Planting in pots or in a garden for ornamental use. This flower is very valuable as a medicinal herb in a antifebrile, a tonic, an anodyne and flower liquor. Propagation by cutting and seeding. Interspecific hybridization with mottled species is recommended. 3. Taraxacum platycarpum ??. Place of collection : Mt. Mi-ryong in Gun-san(the site of Gun-san University). A thick-rooted perennial herb. Yellow flowers come into cull bloom in sunny place from March through April in early spring. This was cultivated for horticulture in Japan at the ancient time. Its occidental species was raised for vegetable salad, but now it is a wild flower. Planting in pots or in a garden. This is very valuable as a medicinal herb in an antituberculosis drug, an edema cure, a stomach tonic and a diuretic. Propagation by seeding and root cutting. 4. Pulsatilla koreana ??

The leaf stalk is long. White fluffs are close together on the five pinnate leaflets. Flowers bloom in April and whit fluffs like silk thread are on their outer sides. But the inner sides have no fluffs and they are red-purple colored. Planting and cultivation in pots. Medicinal use : cure of dysentery, malaria and neuralgia. Propagation by seeding is more suitable than that by ramification, but both of them needs more investigation. 5. Adenophoratriphylla var. japonica ?? Place of collection : the summit of Mt. Mi-ryong in Gun-san. A thick-rooted perennial herb which can be easily found everywhere Leaves are of alternate phyllotaxis and heedle-shape. Both of their ends are narrow and lacerated. Bell-shaped purple flowers bloom from July through september with their heads down. Pot-plauting for ornamental use. Medicinal use : an antidote. Propagation by ramification and cutting. But Seeding is considered better. Good species must be found through study of interspecific hybridization, centering around it with this model species as a central one. 6. Iris ruthenica ??. This flower lives in dry place of mountainside Its rhizome spreads and it buds out. Leaves are line-shaped and grow up to 30cm high after the flowers fading. Purple flowers bloom from April through May. The scape is about 15cm high and one or two buds come out. Planting in pots for ornamental use. Medical use : cure of a soar throat, a styptic, a red spot on one's face, whooping cough, pneumonia and skin disease. Propagation by ramification and seeding. More investigation on line separation and interspecific hybridization about various similar species should be done.

ANISOTROPY OF THE DIURNAL VARIATION OF COSMIC RAY INTENSITY

RYU,J.Y. 群山大學校自然科學硏究所 1987 自然科學硏究 Vol.2 No.-

宇宙線變動의 非等方性은 高速太陽風과 行星間 磁場에 依하여 形成된다. 高速太陽風(HSS) 은 太陽表面의 北極과 南極의 코로나홀에서 끊임없이 불어내며 이와같은 太陽風은 再歸性型이다. 이 外에도 太陽풀레어에 依한 것도 있다. 行星間磁場(IMF)의 方向은 HSS에 隨伴되어 北極코로나홀(NCH)에서의 太陽風은 Away型 IMF, 南極코로나홀(SCH)에서의 太陽風은 Toward型 IMF을 形成한다. 本 論文은 HSS와 宇宙線 變動의 非等方性과의 關係를 探求한다. 太陽活動의 衰退期인 1974년은 코로나홀의 位置가 明確하고 比較的 太陽홀래어가 드문 해로써 太陽風의 27日 周期性이 明確한 해로 地球上 17개 宇宙線 中性子 모니타 觀測所의 資料를 써서 太陽風과 宇宙線의 非等方位性을 檢討한다. 宇宙線變動의 日日變化를 最適化方法을 써서 自由空間에서 非等方性을 決定하였다. HSS는 NCH, SCH마다 R, H, D, Q 4개의 부분으로 나누어서 각부분에서의 宇宙線의 非等方性의 振幅과 位相을 計算해냈다. 位相으로써 18hr LT의 非等方位가 確然하며 이는 宇宙線 强度의 對流-擴散의 理論의 强力한 뒷받침이 된다. 非等方性의 堅度스펙트럼은 양의 符號를 띄고 있다. 振幅은 HSS의 R, H部分의 특기할만한 區別은 볼 수 없고 D.Q部分에서만은 SCH에서의 값이 NCH에서의 값보다 작다. 大體的으로 振幅은 部分에 따른 特異할만한 區別은 없다고 하겠다. Solar diurnal anisotropy of cosmic rays associated with high-speed solarwind streams (HSS) are investigated. Characteristics of modulation of the solar diurnal anisotropy by HSS are examined mainly in 1974, using data from the worldwide network of cosmic-ray neutron monitors(17 stations). From a daily basis analysis based on best-fitting method, it is found that the amplitudes of anisotropy depend remarkably on the location of the coronal holes, from which HSSs are emitted.

Choi,Ho-Seop,Kim,Dong-Hee 群山大學校自然科學硏究所 1988 自然科學硏究 Vol.3 No.-

공통 좌표계로 표시된 4p 원자궤도 함수의 전자 파동 함수에 대한 초미세 상호작용(hyperfine interactions)중 ℓ.I적분의 지름부(radial part)와 각부분(angula part)을 계산하여 이들을 analytic form으로 나타내었다. 이 ℓ.I 적분은 4p 원자궤도 함수에 대한 NMR 화학이동을 계산하는데 이용할 수 있다. For the electronic wave functions for |4p> atomic orbitals expressed in common coordinate system, both the radial part and the spherical polynomial part of the ℓ.I integrals on hyperfine interactions have been evaluated and expressed in analytical form. The ℓ.I integrals may be used to calculate the NMR chemical shift for |4p> atomic orbital.

Amino acid은 共히 Aps., Glu.,이 비교적 많은 量이 있었고 반면 Val., Met., Tyr.등은 小量으로 존재하고 있음이 규명되었다. Amino acid의 組成은 Asp., Thr., Ser., Glu., Gly., Ala., Val., Met., Ile., Leu., Phe., His., Lys., Arg.등이 共通으로 존재하였고 Pro.는 쥐, 토끼, 붕어 에서만 나타났으며 닭과 개구리에는 존재하지 않았다. 그리고 Try.은 쥐, 토끼, 닭에서는 존재하고 있었으나 반면 개구리와 붕어에서는 나타나지 않았다. In order to investigate composition of soluble nervous protein from rat, rabbit, chicken, frog and fish, electrophoretic study were performed for protein patterns, molecular weight and composition of amino acids by SDS-PAGE gradient gel electrophoresis. The number of protein bands, mobility, density of staining and width of protein bands appeared to be specific species. The number of soluble nervous protein bands from rat, rabbit, chicken, frog and fish exhibited 28, 21, 24, 16 and 17 respectively. The distribution of soluble nervous protein bands according to molecular weight conform 17500 to 165000 daltons in rat, 15000 to 115000 daltons in rabbit, 15000 to 135000 daltons in chicken, 15000 to 115000 daltons in frog and 11500 to 105000 daltons in fish. The molecular weight of soluble nervous protein constituted 63% among the all experimental animals at 11500 to 49000 daltons in molecular weight, so it were knew protein of comparative low molecular weight. The most abundant amino acids was Aps. Glu. but exhibited less for Val. Met. Tyr. etc. The composition of amino acids were analysed commonly Asp. Thr. Ser. Glu. Gly. Ala. Val. Met. Ile. Leu. Phe. His. Lys. and Arg., and Pro. exhibited rat. rabbit and fish only but chicken and frog were not observed, also Try. exhibited in rat, rabbit and chicken only but frog and fish were not observed.

2성분 BaO-B₂O₃유리계의 B NMR 연구

차덕준,심문식 群山大學校自然科學硏究所 1989 自然科學硏究 Vol.4 No.-

Nuclear Magnetic Resonance(NMR) techniques have been employed to investigate the bonding structural environment of boron atoms as a function of composition of the binary BaO-B₂O₃glasses. It is found that the ?? NMR spectra consist of the superposition of a narrow line which is due to boron atoms tetrahedrally bonded to four oxygens(BO₄units) and a broad line which is produced by the planar BO₃units. The values of N₄, the fraction of four coordinated boron atoms(BO₄) to total boron atoms were measured and analyzed as a function of R, where R=mol.% BaO/mol.% B₂O₃. From the structural studies of the glasses in the system BaO-B₂O₃, it was confirmed that the structural units accorded with alkali borate glasses.

金愛順 群山大學校自然科學硏究所 1986 自然科學硏究 Vol.1 No.-

If Poly (ethylene Terephthalate) fibers are treated in a solution of sodium hydroxide, they dissolved successively from the their surface, so the handle of PET fibers is improved by the loss of weight. In this study, the effect of only sodium hydroxide treatment and pretreatment of accelerating agent on the hydrolysis of PET fibers were investigated. 1) According to the increase of treating sodium hydroxide concentration, time and temperature, weight loss is increased. 2) The PET fibers was pretreated with amines and organic solvents, the amines used in this experiment were 40% methyl amine, 70% ethyl amine and the organic solvents were 5% benzyl alcohol, 5% buthyl alcohol. The weight loss was remarkably increased in pretreatment of accelerating agent rather than in only sodium hydroxide. 3) The weight loss increased in the order, the PET fibers pretreated with 70% ethyl amine> 40% methyl amine > 5% benzyl alcohol > 5% buthyl alcohol > only sodium hydroxide. From this results, we can assume amorphous region is more selectively degraded than crystal region in PET fibers pretreated with amines and swellen structure of PET fibers formed during the pretreatment with organic solvent, so degradation reaction occurs in the surface as well as in the inferior region of PET fibers when it is treated with sodium hydroxide solution.

有機色素分子와 水容性 高分子 物質에 鹽 및 界面活性劑 添加效果에 관한 吸收分光 光學的 硏究

崔虎燮 群山大學校自然科學硏究所 1986 自然科學硏究 Vol.1 No.-

The structural effect of polyanions and anionic surfactant (AOT) on the binding type of Methylene Blue (MB) was investigated spectrophotometrically. MB was bound to poly (potassium strenesulfonate) (PSS) and poly (Sodium 4-vinyl phenylsulfate) (SVS) in the dimeric or slightly aggregated form and to poly (sodium vinylsulfonate) (SVF) and poly (potassium vinylsulfate) (PVS) in the highly aggregated polymeric form. The aggregation of MB-reversed micelles system is also similiar to the case of MB-poly-anion. In the case of reversed micelles the amount of water destroys MB aggregation.
