김덕술,Kim, Ducksool 한국융합신호처리학회 2021 융합신호처리학회 논문지 (JISPS) Vol.22 No.1

본 연구는 오존화 올리브오일이 피부 질환에 우수한 치료효과를 가진다는 연구 결과가 알려지면서 오존을 피부 질환치료에 사용하려는 다양한 시도가 있어 왔지만, 적절한 계측 절차가 수립되지 않아 국내에서는 임상적으로 가치가 있는 양질의 데이터를 확보할 수 없었다. 일반적으로 화장품의 성능확인을 위한 목적으로 동물실험을 통해 실측 데이터 계측을 진행하는 경우는 많지 않지 않으나, 독성실험의 경우 피부의 반응을 정확히 계측하는 것이 반드시 필요한 사항으로 권고되고 있어 본 실험이 실시되었다. 본 실험에서는 실험 Rabbit에 대한 오존화오일(고농도)에 대한 피부자극 평가를 위하여 오존화오일(고농도)을 털을 제거하여 피부가 노출된 Rabbit의 등 부위에 도포한 후 24시간 동안 영상처리장치와 육안 검사를 통해 피부 반응을 관찰하여 피부자극 평가를 위한 데이터를 확보하고자 하였고 오존화오일(고농도)의 의한 일반적인 반응, 사망과 같은 반응을 함께 측정하는 과정을 진행하였다. 총 24시간 이내의 결과에서 실험에 사용된 동물들 모두에서 시험물질 처치 부위의 육안관찰, 영상촬영을 통한 이상 반응은 관찰되지 않았고 사망과 같은 돌발적인 이상반응 역시 확인되지 않아 오존화오일(고농도)의 생체 안전성을 확인할 수 있었다. This study has attempted to use ozone for the treatment of skin diseases as research results that ozonated olive oil has an excellent therapeutic effect on skin diseases are known. However, there is hardly any accurate data in Korea. Usually, animal tests related to cosmetics are not performed, but toxicity tests were conducted because they were absolutely necessary. In general, there are not many cases of measuring actual data through animal tests for the purpose of confirming the performance of cosmetics, but in the case of toxicity tests, it is recommended to accurately measure skin reactions, so this experiment was conducted. In this experiment, in order to evaluate the skin irritation of ozonated oil (high concentration) on the rabbit, the test substance was applied to the back of the rabbit for 24 hours, and then mortality, general symptoms and skin irritation were evaluated. Experimental Results As a result of evaluating the treatment site of the test substance after a certain period of time, no skin irritation was observed in all animals.

올리브 오일의 오존화 혼합비율을 높여주는 오존수 확산장치개발에 관한 연구

김덕술 한국유화학회 2014 한국응용과학기술학회지 Vol.31 No.4

본 연구는 생활주변에서 오존수를 쉽게 활용할 수 있도록 오존수 발생장치의 활용성을 증가시키고 한 동작으로 작동하는 시스템을 개발하고자 한다. 더 나아가 올리브 오일과 오존과 반응시켜 제조하는 기술에 적용하고자 한다. 기존의 경우 대부분이 오존수 시스템이 아닌 오존발생기 위주의 제품이 많다. 오존수기의 경우 펌프로 강제 흡입시키는 일반압력 방식으로 오존가스 누출 위험요소가 내포 되어 있으나, 본 과제의 경우 인젝터를 이용하여 물의 유입여부에 따른 오존의 발생과 흡입을 제한하고 있어 기존 제품의 오존 누출에 의한 위험을 최소화하였다. 인젝터 방식의 단점에도 불구하고 미생물 살균능을 유지하는 것으로 본 연구에서 사용된 인젝터 방식 오존수 제조 장치의 효용성을 알 수 있었다. This study is to increase the utilization of the ozonated water generator to make it easier to take advantage of the ozone water in the world today, there will be to develop a system that operates in one motion. Furthermore, olive oil and ozone is reacted with the wish to apply to the manufacturing technology. In the case of many existing products ozone generator driven mostly non-ozone system. In the case of ozone, but handwriting is implied general way pressure ozone gas leakage risks of suction force to the pump, it is the case of the challenge by using the injector, and limit the generation of ozone and ozone inhalation according to whether the water inlet leakage of existing products risk due to minimized. Despite the disadvantages of the injector system was found the effectiveness of the ozonated water production unit injector system used in this study to maintain the microbiological disinfection performance.

침전법을 이용한 이산화티탄 입자 제조에 알콜과 온도가 미치는 영향에 관한 연구

김덕술 한국유화학회 2012 한국응용과학기술학회지 Vol.29 No.3

본 연구에서는 TiO2 입자를 얻을 수 있는 침전법을 이용하여 TiO2 입자를 제조하였다. TiO2 입자 제조시 사용되는 알콜 용매의 종류와 온도 변화 등의 매개변수가 TiO2 입자의 결정 구조, 입자의 크기 및 형태에 미치는 영향을 조사하였다. TiO2 입자제조시 용매로 사용한 알콜 종류인 methyl alcohol, iso-propylalcohol, 그리고 tert-butylalcohol를 scanning electron microscope(SEM) 분석한 결과 iso-propylalcohol이 가장 좋은 결과를 가져왔다. 그리고 온도 변화를 열분석법을 사용한 결과 200℃에서 500℃까지는 아나타제 구조를 유지하였으나, 800℃에서는 루틸 구조로 전환되었다. Using the Sedimentation method it's possible to get TiO2 particle from which by this research, TiO2 particle was produced. The parameter in the kind of the temperature and the alcohol solvent used TiO2 particle production investigated crystal structure of TiO2 particle and the influence exerted on the size of the particle and the form. After scanning electron microscope (SEM) analyzed methyl alcohol, iso-propylalcohol and tert-butylalcohol used by a solvent at the TiO2 particle production, iso-propylalcohol was most effective. And after an thermogravimetric analyzer method was used, the anatase structure was maintained 500℃ by 200℃, but it was converted by the rutile structure by 800℃.

생체 적합성이 확보를 위한 오존화 올리브오일 제조 장치 구현

김덕술 한국융합신호처리학회 2023 융합신호처리학회 논문지 (JISPS) Vol.24 No.3

As research results showed that ozonated olive oil has excellent therapeutic effects on skin diseases, attempts were made to develop cosmetics manufacturing technology using ozone. Ozone is harmful to the human body, so a separate facility must be prepared to manufacture ozonated olive oil as a cosmetic raw material. The manufacturing device developed in this study was designed as an optimized process for manufacturing cosmetics while ensuring the safety of workers involved in production. To verify the ozonated olive oil produced from the implemented device, a toxicity test was conducted on animals. After applying ozonated oil (high concentration) to the rabbit's back for 24 hours, mortality, general symptoms and symptoms were measured. A skin irritation evaluation was performed. As a result of the experiment, as a result of evaluating the test substance treatment area after a certain period of time, it was confirmed that no skin irritation was observed in all animals, confirming the safety of the ozonated oil production process and the safety of the product.

근육의 전기자극에 의한 X선 회절 분석연구

김덕술,송주영 한국생명과학회 1998 생명과학회지 Vol.8 No.4

A considerable change observed in X-ray diffraction during the muscle contraction was that the movement of myosin head and conformational change of contractile monecules were occurred in the muscle contraction. Time slice requires tension peak after the onset of stimulation and the height of tension peak depends on the number of twitch cycle. The intensity of I$_{11}$, I$_{10}$, 143${\AA}$ reflection is measured with 5ms time resolution and is recorded in isometric tension. The peak height of I$_{11}$ and 143${\AA}$ intensity is changed after the onset of a stimulation I$_{i}$, and the length of twitch is shortened by successive twitches in the case of stimulation TI$_{i}$. On the other hand, the peak height of I$_{11}$ and 215${\AA}$ intensity starts to decrease at the 1st twitch and remains constant at low peak hight without appreciable recovery during the contraction term. In the case of uccessive twitch stimulation, the myosin heads of muscle are once moved from their resting position and never returned to their initial position.

온도 영향에 따른 Myosin Head의 SH 구조 변화 연구

김덕술,송주영 한국생명과학회 1999 생명과학회지 Vol.9 No.6

The effect of temperature on the structure change of the SH of myosin head have been investigated with improved resolution by x-ray diffraction using synchrotron radiation. The movement of myosin head and conformational change of contractile molecules were occurred in the muscle contraction. IASL (iodo acetamide) and MSL (maleimide) disordered the orderly helix arrangement of myosin in the rest state of spin level. The temperature effect on the structure change was great at the UL in the equatorial reflection. But those of IASL and MSL were minor. Equatorial reflection (10, 11) change inferred that myosin head was moved to the vicinity of actin filament by temperature change (from $25^{\circ}C$ to $0^{\circ}C$) at UL, but spin level was not changed. The intensity change of 143 $\AA$ and 72 $\AA$ could offer information of the mass profection of population of myosin heads along the filament axis. The slope of intensity profile of the mass profection of 143$\AA$ and reflection of MSL is appeared sharply and those of UL and IASL were not changed. The decrease of MSL actin reflection at 51 $\AA$ and 59 $\AA$ in the actin reflection change refers that the shifted myosin head binds a certain actin or changes an actin structure. From these results, we could conclude that IASL and MSL were spin labeled on SH of myosin head and disordered the helix arrangement of actin.
