홍삼 물 추출물이 효소활성에 미치는 영향을 조사하기 위하여 먼저 홍삼분말에 methyl alcohol을 가하여 지용성 성분과 사포닌 성분을 추출하여 제거하였다. 그 잔사에 정제수를 가하여 추출한 뒤 추출물을 제조하였고, 투석막을 이용하여 분자량 크기별로 분획한 뒤 trypsin의 활성에 미치는 영향을 조사하였다. 몇 가지 분획 중에서 분자량 1,000∼12,000 사이의 분획이 trypsin 활성을 가장 강하게 증가시켰다. 분자량 1,000∼12,000 사이의 분획을 여러 가지 농도별로 첨가하여 trypsin 활성에 미치는 영향을 조사한 결과 2.9${\times}$$10^{-3}$%에서 15% 정도 촉진되었으며, 농도가 높아질수록 trypsin 활성도 증가하여 9${\times}$$10^{-2}$%에서 최고의 활성을 보이다가 그 이상의 농도에서는 감소하였다. Trypsin의 casein 분해에 있어서 물 추출물은 Km 값을 낮게하고 Vmax 값은 증가기켰다. 물 추출물을 부분 정제하여 몇 가지 특성을 조사한 겨로가 ninhydrin, DNS 및 Folin시약에 양성반응을 나타내는 것으로 보아 함질소 화합물이라고 판단된다.

Global warming is regarded as one of the most critical issues that should be taken care of by the entire global community as it threatens the survival of mankind. South Korea, in particular, undergoes faster warming than the average rate of global warming. South Korea has revealed various warming rates and trends being surrounded by sea on three sides and having complex terrains dominated by mountains. The rates vary according to regions and their urbanization and industrialization. Differences also derive from seasons and weather elements. Changes to the highest, mean, and lowest temperature are also different according to the characteristics of regions and observatories, which is more apparent where the force of artificial weather applies. In an urban area, temperature gaps tend to decrease as the lowest temperature rises more than the highest temperature. Meanwhile, temperature gaps grow further in a coastal or country region where the force of artificial weather is small and the force of natural weather prevails. In this study, the investigator analyzed the changes to the weather elements of 11 observation spots that had gone through no changes in terms of observation environment since 1961, were consecutively observed, and had the quality of their observation data monitored on an ongoing basis. Using the results, I tried to identify natural and artificial causes affecting certain spots. Located on the east coast of the Asian Continent, South Korea sees weather changing very dynamically. Having huge influences on our weather, China has achieved very rapid industrialization for the last 30 years and produced more and more greenhouse gases and air pollution due to large-size development projects. All those phenomena affect our weather system in significant ways. Global warming continues due to various reasons with regional change differences. Thus the analysis results of the study will hopefully serve as basic data of weather statistics with which to set up countermeasures against climate changes.

Objectives : Saam acupuncture has evident principles of prescription based on acupuncture tonification and purgation of Nan-gyeong but many prescriptions of Saam acupuncture are not typical patterns. This paper studies principles of prescriptions of the king fire and the premier fire. Methods : Through investigation of many medical documents concerning king fire and the premier fire, the author explained of physiological and pathological principle of king and the premier fire, also explained of interacting mechanism through five element. And The theoretical authorities of analysis are Nan-gyeong, works of Joo dan-gye and Li dong-won. Results & Conclusion : 1. The sufficiency and the control of the water is the key to treat the disease by fire. Considering the attack and the treatment of disease, heart and liver give rise to fire in its early stage and kidney and lung are the key to treatment. 2. Consequently the pathology of the disease from fire is corresponding to the theory- Yang Sufficient, Yin Deficient- of Joo dan-gye. It seems that the theory of Joo dan-gye influenced on the medical theory of Saam Acupuncture. 3. On that account I believe that the study of medical theories of the Geum and Won Dynasty that various medical theories had appeared is very available for Saam Acupuncture. At present global warming is accelerating because environmental pollution has been increasing. Therefore the damage of fire to human body will be more and more severe and extensive. Because in the future medical plants will not be free from environmental pollution, acupuncture will be very confidential treatment.

오래 전부터 생물학적 폐수처리 방법에 대한 다양한 연구들이 꾸준히 진행되고 있으나, 전통적인 염료 염색 폐수처리 방법들은 다소 비효율적이다. 최근 들어 이를 극복하기 위하여 특정 미생물이나 효소를 이용한 연구들이 활발히 진행되고 있다. 본 연구에서는 백색부후균이 생산하는 리그닌 효소에 의한 생물처리 방법으로, 아조계(azo) 염료인 Reactive black 5를 적용하였으며, 다양한 농도에 따른 분해경향을 확인하였다. 미생물 재이용과 장기간 운전, 효율적인 유기물 제거의 가능성을 확인하기 위해 i)생물학적 처리와 ii)분리막 처리공정과 iii)이 두 가지를 결합한 공정의 처리 효율을 비교하였다. 결합공정을 사용하였을 때 색도제거율이 100%였으며, 총유기물(TOC) 제거율은 70% 이상으로 각 단위공정만으로 처리하였을 때보다 더 효율적인 결과를 보였다. 또한, 생물반응에서 배양말기까지 유지된 효소활성(40 U/ml laccase and 300-600 U/ml MnP)을 통해 미생물 재이용의 가능성을 확인하였다.

Liquid crystal known as a rheological barrier to coaleseence of oil dorplets. increases. emulsion stability, water-holding capacity and promotes active material penetration to skin. Some investigation for its rheological characteristics have been reported but its relations to consumer perception have been rarely published. In this study oil/water emulsion and oil/liquid crystal/water systems were manufactured using the same composition of Behenyltrimethylammonium chloride/Cetostearyl alcohol/Lanolin oil. and rheological properties of each system were investigated with Cone and Plate rheometer. The formation of liquid crystalline phase was observed with polarized microscope and Differential Scanning Calorimeter. Continuous shear experiment, creep yield and water holding capacity were measured for oil/water and oil/liquid crystal/water systems. The results were compared with sensory evaluations. Oil/liquid crystal/water system showed higher viscosity at the same shear rate, higher viscoelasticity and higher yield stress than oil/water system. These properties were expected to show good spreadability and excellent richness without waxiness I hair care products of creme type. This expectation was consistent with the results of sensory experiments. Water-holding capacity was evaluated by measuring residual water of specimens at specific temperature and relative humidity, Oil/liquid crystal/water system was proved to have ability to hold water in comparison with oil/water system. The results indicated that oil/liquid crystal/water system was of benefit to rheological properties creme type hair care products.
