  • 덩굴차의 차로서 맛에 관계되는 성분과 약리 효과를 타나내는 saponin에 대해서 알아보고, 또한 이들 성분이 산지에 따라 차이가 있는지를 알아보고자 실시된 실험 결과 다음과 같은 결론을 얻었다. 1. 일반성분의 함량중 조지방은 거창산에 1.62%로 가장 많았고, 수원산 1.56%, 및 울릉도산 1.00%의 순이었다. 조단백은 거창산이 17.83%. 수원산 15.83%, 및 울릉도산 12.28%로 나타났으며, 회분의 함량은 거창산이 14.80%, 울릉도산이 10.17%, 및 수원산이 9.34%로 조지방, 조단백질, 회분이 모두 거창산에 가장 많은 것으로 나타났다. 2. 환원당의 함량은 수원산이 3.3%로 가장 높았고, 거창산이 1.3%, 울릉도산이 0.5%로 나타났다. 각각의 유리당의 함량은 수원산과 거창산 모두에서 과당과 포도당의 양이 가장 높았다. 3. 아미노산의 함량은 수원산이 1.41%로 가장 높았고, 거창산이 1.37%. 울릉도산이 0.53%로 가장 낮았다. Asp. Thr. Ser. Glu. Gly. Ala. Val. Met. Ileu. Leu. Tyr. Phe. Lys. His. Arg.및 Try.외 16종의 아미노산이 검출되었는데 glutamic acid와 methionine을 제외하고는 수원산의 아미노산 함량이 거창산이나 울릉도산에 비해 모두 높았으며, glutamic acid는 울릉도산에서, methionine은 거창산에서 가장 높았다. 공통적으로 함량이 많은 아미노산의 순은 Gly. Asp. 및 Glu였고, 가장 적은 아미노산의 순은 Lys. Ser. 및 Try. 이었다. 4. 무기질은 칼슘, 망간. 카드뮴, 칼륨, 나트륨, 납, 마그네슘, 철, 아연, 구리 등 10종이 검출되었는데 카드뮴, 나트륨, 마그네슘, 아연, 구리의 함량은 울릉도산에서 가장 높았고, 칼슘, 망간. 철은 거창산에서 가장 높게 나타났으며. 칼륨은 수원산에서 가장 높았다. 5. Tannin은 거창산이 6.3%로써 수원산 2.5%. 이나 울릉도산 2.6%에 비해 월등히 많은 양을 함유하고 있다. Caffeine과 vitamin C는 수원, 거창 및 울릉도산이 1.77%, 수원산이 1.49%로 나타났으며, 덩굴차에는 인삼 saponin성분과 동일한 saponin은 존재하지 않는 것으로 나타났다. 위 실험 결과에 나타난 것과 같이 산지에 따라서 그 성분의 차이가 있으므로 그 맛이나 향기, 색깔 또한 차이가 있을 것으로 사료된다. 그러므로 앞으로 관능검사나 독특한 향기성분, 색소성분등을 분석연구한다면 좀더 우리 입맛에 맞는 맛을 가진 보편성을 가진 차로 한층 더 개발될 수 있으리라 생각된다.

  • 본 연구는 저토심 옥상녹화모듈의 빗물유출 및 도시열섬 저감효과를 정량적으로 평가하기 위해, 저토심 경사 평지붕 녹화모듈의 저류 및 증발산 특성을 규명한 것이다. 이를 위해 기린초를 식재한 라이시미터(깊이 100mm)를 4방향(동, 서, 남, 북)의 50% 경사 지붕과 평지붕 위에 구축하였다. 그리고 저토심 경사지붕 및 평지붕 녹화모듈을 대상으로 연간 수분보유량 및 저류량과 증발산량 그리고 옥상과 평지붕 녹화모듈의 표면온도를 2012년 9월 1일부터 2013년 8월 31일까지 1년간 연속적으로 측정하였다. 측정된 자료를 근거로 분석한 녹화모듈의 저류 및 증발산 특성은 다음과 같다. 경사지붕 녹화모듈의 수분보유량은 눈이 오는 겨울철을 제외하면 강우 직후 8.7~28.4mm까지 상승하였으며, 무강우 지속 시 3.3mm까지 저하하는 것으로 나타났다. 경사지붕 녹화모듈은 최대 22.2mm까지 강우를 저류했던 것으로 나타났다. 녹화모듈의 강우량 대비 강우 저류율 예측식은 경사지붕의 경우 [강우 저류율(%)=-18.37 ln(강우량(mm))+107.75, $R^2$=0.79], 평지붕의 경우 [강우 저류율(%)=-22.64 ln강우량(mm))+130.8, $R^2$=0.81]였다. 경사지붕 녹화모듈의 증발산량은 강우 후 경과일수에 따라 급격히 감소하였으며, 봄철과 가을철에는 로그함수형으로, 여름철에는 거듭제곱함수형으로 감소하였다. 그리고 경사지붕 녹화모듈의 강우 후 일증발산량은 여름 > 봄 > 가을 > 겨울 순으로 높게 나타났다. 이는 일사량 및 기온의 차이에 의한 것으로 사료된다. 녹화모듈의 증발산량은 강우 후 3~5일간 2~7mm/day에서부터 1mm/day 미만으로 급격히 감소하였으며, 이후 완만하게 감소하였다. 이는 녹화모듈에 식재된 기린초는 수분이 충분할 경우에는 수분을 급격히 소비하고, 수분이 부족할 때는 수분을 보존한다는 것을 시사한다. 여름철 알베도는 옥상면이 0.151, 옥상녹화면이 0.137 그리고 겨울철 알베도는 옥상면이 0.165, 옥상녹화면이 0.165로 나타나, 옥상면과 옥상녹화면의 알베도에는 큰 차이가 없었다. 여름철 녹화에 의한 표면온도의 저감효과는 일평균표면온도가 $1.6{\sim}13.8^{\circ}C$(평균 $9.7^{\circ}C$), 일최고표면온도가 $6.2{\sim}17.6^{\circ}C$(평균 $11.2^{\circ}C$)로 나타났다. 겨울철 녹화에 의한 온도 차이는 일평균 표면온도가 $-2.4{\sim}1.3^{\circ}C$(평균 $-0.4^{\circ}C$), 일최고표면온도가 $-4.2{\sim}2.6^{\circ}C$(평균 $0.0^{\circ}C$)로 크게 나타나지 않았다. 증발산량이 증가함에 따라 녹화에 의한 저감온도가 선형함수형으로 커지는 것으로 나타났으며, 증발산량에 따른 저감온도의 예측식은 [저감온도($^{\circ}C$)=$1.4361{\times}$증발산량(mm)+8.83, $R^2$=0.59]였다. 무강우 지속 시 녹화에 의한 표면온도 저감은 세덤 수관에 의한 차양효과에 의한 것으로 판단되었다. 본 연구 결과, 녹화모듈에 의한 저토심 옥상녹화는 저류와 증발산 작용에 의해 빗물 유출 및 도시열섬 관리에 긍정적인 효과를 준다는 것을 규명하였다. 또한 기린초는 무관수 저토심 옥상녹화용 수종으로 이상적 식물재료이며, 장기적인 도시열섬 완화라는 측면에서는 기린초의 증발산효과뿐 아니라 차양효과를 고려해야 한다는 것을 제시하였다.

  • The intention of this study is to apprehend the con. tents and methods of herb remedies that are commonly conducted when there are health-problem cases of ENT, eyes, teeth and skin. Methods of this study are divided into two stages : 1) For a period of six months from December 1994 to June 1995, some 40 persons who are believed to be well versed with herb remedies have been randomly chosen, and we made a survey on herb remedies by symptoms: and 2) we have endeavored to make their grounds evident through the studies on literatures with the focus on the basic data collected. Their results are as follows: 1) When one feels a pain in ears, such herb remedies are employed as pouring the vapor into ears, which is made by steaming Alaska pollack, or as applying or wiping with the juices of radish or the ginkgo, or' alum. Applying the radish juice is effective for sterilization and fever removal: and applying the ginkgo juice is effective for cleanliness. But, plastering alum, sesame oil or castor oil, or pouring the vapor of Alaska pollack into ears are perhaps effective but do not have any pharmacologic grounds. 2) When one bleeds at the nose, such kinds of herb remedies are applied as stimulating nose or head with cold water, pressing nose or ridge of nose, or filling up nares with mashed mugworts. In addition, they have utilized garlic or leeks. Such methods as stimulating with cold water or just pressing nose and ridge of nose is based on reasonable grounds, i.e. vasoconstriction and vascular compression ; and applying mashed garlic on the sole of foot is good for the circulation of Qui ; and the use of mugworts and leeks is based upon the pharmacological function of hemostasis. 3) When one feels a sore throat such kinds of herb remedies are employed as gargling or rinsing throat with brine, drinking hot gruel or water, or drinking the juice of mugwort, radish, ginger or Chinese quince. Gargling with brine or drinking the juice of mugwort, radish or ginger is based upon the pharmacological function of pain alleviation, fever removal, and detoxication. 4) When a boil is formed in mouth, such herb remedies are applied as spreading honey, brine or alum water, and taking gall nut, Chinese matrimony vine, lotus root, etc, for drugs. Spreading honey, brine or water that is made by infusing gallnut, Chinese matrimony vine, lotus root is based upon such functions as hematosis, astriction, antibacterial, and antiphlogistic, Alum, eggplant and licorice are said to be effective, but their pharmacological effects have no grounds. 5) When one has conjunctivitis such herb remedies are commonly applied as irrigation with brine and dropping breast milk in eyes. Moreover, such other drugs are used as plantain. shepherd's purse, and purslane, etc. The use of brine, breast milk, plantain, shepherd's purse and purslane is based upon such functions as sterilization, antiphlogistic, disinfection and pain relieving. Eriocaulon sieboldianum, bean stem, bean pod and narcissus leaves are said to be effective, but their pharmacological action have no basis. When one has a stye, such herb remedies are applied as extracting eyelashes, stimulating by a massage of middle finger, third finger or big toe, as well as sear ing with a heated bamboo comb that is fine-toothed. Other than these, plantain and nightshade's nuts are used as drugs for it. Extracting eyelashes corresponds with exclusing suppurative node and draining the stye of pus ; and the use of plantain is based upon disinfection: and nightshade's nuts are said to be effective, however, their pharmacological action has no grounds. 6) For a treatment of toothache, such herb remedies are commonly employed as rinsing mouth with brine and holding cold water or gasoline in the mouth ; and as the drugs that are believed to be effective have been Welsh onion, ginger and castor-oil, plant, etc. The use of Welsh onion is based upon pain killing, antiinflammatory actions, and the use of ginger is based upon detoxication and disinfection ; and seeds of castor-oil plants are said to be effective, but they have no pharmacological basis. 7) When one has hives, such herb remedies are commonly applied as rubbing burned straw in affected parts, exposing to its smoke, rubbing with salt, sweeping down with a broom, and spreading and drinking boiled water of trifoliate orange. The use of cassia tora seeds, walnut, aloe and radish is said to be effective. The use of cassia tor a seeds has the functions of intestinal order, anti-paralysis, etc. The use of walnut has resulted in an increase of blood by invigorating spirits ; and the use of aloe is based upon disinfection, antibiotic, anti-salt, antihistamine and detoxication action. But, the effects of radish juice and straw's smoke have no pharmacological grounds. 8) When one gets a boil, such herb remedies are commonly used as applying a plaster, paste of flour mixed with yolk, soy sauce or honey, as well as spreading pounded elm tree. Other remedies that have been said to be effective are ; heating with mugwort, brine, wild rocambole, aloe, onion, squid's bone, etc. The use of mugwort is based upon pain killing, astringent antiinflammatory and tranquility. Wild rocambole is based upon the generation and maintenance functions of cell-joining textures ; elm tree upon antiphlogistic ; aloe upon fever removal and antiphlogistic ; onion on pain killing, fever removal, antiphlogistic and tranquility ; squid's bone on astriction: and brine or vinegar on sterilization. Pine resin and gardenia seed are said to be effective, but they have no pharmacological basis. 9) When one cuts his skin, such herb remedies are commonly employed as spreading mugwort's juice or squid's bone powder, or pressing the wounds. In addition, kalopanax, onion and fine soil are employed. The use of mugwort, kalopanax and squid's bone is based upon such functions as hemostasis, sedation, pain killing, antibacterial ; and fine soil is said to be effective, but it has no pharmacological basis. 10) When one suffers from whitlow, such herb remedies are commonly utilized as heating with boiled soy sauce, spreading soybean paste, or dipping into eggs, etc. Other drugs that have been employed are onion root, brine, eggplant, potato, loach, etc. The use of onion is based upon pain killing and antiphlogistic functions ; and that of brine upon antiphlogistic function. The use of soy sauce or soybean paste, fomentation, eggplant, potato and loach is said to be effective, but it has no pharmacblogic ground. 11) For the treatment of frostbite, such herb remedies are commonly used as dipping the affected part into frozen soybean sack, using boiled water of eggplant stem, garlic caulis, onion, hot pepper, caulis. Onion is based upon antiphlogistic and tranquility actions garlic upon disintection, metabolic exacerbation, tonic and aphrodisiac actions and the use of eggplant and hot pepper is based upon help blood circulation, dissolution and excretion of waste matters in vein. 12) For the treatment of burn, such herb remedies or drugs are commonly used as cleansing with Korean gin, spreading eggs, cleansing with cold water and soap water ; and as brine, cactus, moss, soybean paste, oil, etc. The cleansing with Korean gin, cold water, soap water, brine, vinegar is based upon cleaning and sterilizing functions ; and the use of cucumber is based upon nu. trition provision, and strengthening of resisting power by adjustment of metabolism. The use of potato, cactus, moss, oil and eggs is said to be effective, but their phamacological functions are not clarified. In view of the above results, we can realize that the drugs that have been employed in herb remedies are quite diverse. However, in regard to majority of herb remedies that have been employed by symptoms, the pharmacological functions of their drugs have not been clarified, and they are merely known as effective. Furthermore, they have not been recorded in the literature as yet ; and we confirm that there have been many herb remedies that were executed without the proper knowlege of their effects. It is now our view that the results of this survey may be utilized for consulting data in regard to the use of herb remedies.
