Objectives : To maintain a healthy skin condition, the role of moisture in the stratum corneum is important. We use soap in our daily life, so we wanted to observe the changes of the skin moisture using herbal CP soap. Four kinds of herbal CP soaps were prepared and their effects on skin moisture were compared. Methods: We surveyed 39 students at A University to determine their subjective skin condition, lifestyle and washing habits. Then, a facial analysis test was performed. We made herbal CP soaps using Kyungohkgo, Hwangryunhaedoktang, Seosiokyongsan and Baeksoooh and distributed them to experiment participants. Prior to the experiment, their skin condition was checked and skin condition was assessed using Facial Diagnosis System three times in total. After the experiment, the change of skin was measured and analyzed. Results: As a result of examining the skin moisture according to the using of the herbal CP soap by the participants, the skin moisture was gradually increased compared with before use. The moisture content increased after 6 weeks of use compared to before using Seosiokyongsan, Hwangryunhaedoktang, Kyungohkgo CP soap compared to before use. But there was no significant difference between 3 weeks and 6 weeks of use compared to before use. As a result of using Baeksoo-oh CP soap, the skin moisture of the experimental participants was continuously increased. Conclusion: Natural CP soaps are believed to have a beneficial effect in increasing the moisture content of facial skin.

Objectives : Acne is a common disease that affects more than 70% of adolescents. Acne patients have a poor quality of life compared to patients with other skin diseases. We tried to demonstrate the effectiveness of acne treatment using cleansing soap which is easily used in daily life. Methods : We selected 20 students with acne symptoms on their facial skin. We made herbal Cp (Cold process) soaps using Seosiokyongsan, Kyungohkgo, Hwangryunhaedoktang and Baeksoooh and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal Cp soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. Acne status was classified into 6 stages according to KAGS and acne status was also measured 3 times in total. After the experiment, the changes of skin were analyzed through facial analysis test. Results : Based on the KAGS classification, the condition of acne has improved as a whole. The state of moisture was gradually increased and the state of skin oil was significantly decreased after 6 weeks of using soap compared to before using soap. Conclusions : Cp soaps made from four kinds of herbal medicine are believed to improve the condition of acne by increasing the moisture of the facial skin and decreasing the skin oil content.

무엇이 응급의학과 전문의들의 직무만족도에 영향을 주는가? 2020년 응급의학과 전문의 총조사 중심

Objective: This study aimed to find changes in the job satisfaction of emergency physicians (EP) and suggest ways to objectively measure indicators of satisfaction for future surveys. Methods: A total of 2,138 emergency physicians were surveyed, using email questionnaires from January to February of 2021. The factors related to their job satisfaction were analyzed. Results: Emergency physicians’ satisfaction was low. The average number of times they experienced violence per year was 4.3±4.9 per year. Work intensity and salary satisfaction improved than those in the 2010, and 2015 Korean Emergency Physician Survey (KEPS). Health status, such as drowsiness, and depression rates, were low. Forty-three percentage of EPs said they would reapply for the emergency specialty. Conclusion: Despite the increase in extrinsic indicators, job satisfaction remained low compared to those in the 2010, and 2015 KEPS. To improve job satisfaction, non-quantitative factors should be considered. It would be necessary to evolve a separate survey on job satisfaction and conduct regular surveys in this regard.

Objective : We have reported the effects of Seosiokyongsan (SSOOS) cp soap on increasing skin moisture, decreasing pore size, and reducing acne symptoms on previous studies. But in the case of SSOOS soap, many soap bases were used in the making process. So we could not determine whether the above test results were the effect of soap bases or SSOOS herb medicine. Therefore, We conducted this clinical test to find out the effect of SSOOS itself. Methods : We made two kinds of soap. One type was made of cp soap using only soap bases and gave them to 10 subjects. The other type was cp soap made by adding SSOOS to the soap base and gave them to 25 subjects. The other 10 subjects did not limit the soap. Subjects were asked to wash their face with soap in the morning and evening for six weeks. The test was conducted three times and the results were compared and analyzed. Results : In the test group using the SSOOS soap, the oil in the U zone was significantly decreased and the moisture was significantly increased compared to other two control groups. Pores size and pigmentation were decreased but not significant. There was a significant increase in moisture in the soap base group, but that was a slight increase compared to SSOOS soap. There was no significant results in the without soap control group. Conclusion : SSOOS soap was found to have a significant effect on facial skin as cleansing products.

Objectives : The pores are the openings of sebaceous glands or apocrine glands. They are enlarged by various factors such as sex, age, genetic influence, sebum secretion, acne and so on. When the pores are visually recognizable, they become aesthetically problematic. There are various methods of treating pores, but we have tried to develop a method to reduce pore size by using daily cleanser. Methods : Facial skin examination was performed on 104 students of A university. Among them, 10 persons with large pore size were selected. We surveyed 72 students to determine their subjective skin condition, lifestyle, and washing habits etc. We made herbal fermented soaps using Seosiokyongsan and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal fermented soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. After the experiment, the changes of skin were measured and analyzed through facial analysis test. Results : In our experiment, the early 20s, 9.6% of the students had slightly larger pores. For students with large pores, there was a high likelihood of side effects from using facial products. Using the fermented soap made of Seosiokyongsan, the average size of the pores and the number of large-sized pores were significantly reduced. Conclusion : Seosiokyongsan fermented soap can effectively reduce especially the large size of pores.

Divergences in the Theory of Cyclotron Resonance Lineshape

최상돈,고정대,최치규,홍성락,류재연 제주대학교 1990 논문집 Vol.31 No.-

불순물이나 포논과 상호작용하는 전자계에 대한 전기전도도템서와 사이클로트론 공명 선모양 함수를 도출하였다. 전기전도도텐서를 얻는 과정에서 Kubo공식을 이용하는데 타이론에서 무시한 보정항인 충돌항을 고려하고 이 항을 열적이완시간과 관련시켜 일반적인 형태를 얻었다. 섭동향을 계산하는데 Argyres와 Sigel의 사영연산자방법과 본 논문에서 정의한 사영연산자를 토대로 한 운동방정식방법을 다루었는데 이들은 서로 동일한 결과로 나타남을 알 수 있었다. 또한 최저차수에서 구한 선모양 함수를 타이론의 결과와 비교했고 고차항에서는 타이론에서 발산하는 것과는 달리 열적이완시간이 포함됨으로써 발산항이 존재하지 않음을 알 수 있다. A new theory of cyclotron resonance lineshape for the system of electrons in interaction with impurities of phonons is introduced. The collision term appearing in the Kubo formalism is dealt with in the relaxation tine approximation. The many body conductivity tensor is reduced to two different forms in the single particle formalism. But the two conductivity formulas give the same lineshape function, implying that the two techniques are identical. The thermal relaxation time included in the lineshape function is finite , resulting in the disappearance of any danger of divergence in some higher order terms usually excluded in the formula.

Objectives: The purpose of this study is to analyze the causes of short stature through a clinical review of factors related to childhood height growth. So we can find the way to meet the needs of the heightism which is widely spread among modern people. Methods: Among 160 patients who came to Andong B oriental clinic for the purpose of growth therapy, 112 children whose height was smaller than other normal children were analyzed. When the children first came to the clinic, we checked their height and weight. The parents' height was recorded through a questionnaire. The relationship between obesity index and height growth was examined through growth plate test and Inbody test. We want to identify the genetic factors related to parental factors based on the data of the parent height. Results: For short stature children, weight was often normal or low. When we examined the relationship between parental genetic factors and child growth, we found that they were more influenced by father’s height rather than mother’s. We investigated the correlation between skeletal maturity and the five viscera. There was no apparent correlation between skeletal maturity and the five viscera but we found that there was some degree of relevance. Conclusions: For short stature children, the weight was often normal or low and parental genetic factors were more influenced by father than by mother. In the case of bone maturity it did not show a direct correlation between the five viscera.

We realized CGH display of moving objects with an optical addressed spatial light modulator. CGH was calculated by the horizontal parallex method for saving a calculating time, and calculation speed was improved by making a lookup table of trigonometric function and root calculation. This lookup table was applied to a low resolution SLM, and succeeded in a simultaneous display of the three hologram images by the scanning method. 본 연구는 움직이는 물체의 컴퓨터 합성 홀로그래피(CGH)의 동영상 디스프레이를 액정형 공간광변조기(OASLM)에 의하여 시도하였다. CGH는 계산하는 시간을 줄이기 위해서 horizontal parallex 방법을 사용하였고, 또한 계산하는데 시간이 오래 걸리는 삼각함수 계산과 자승근 계산부분을 미리 lookup table로 만들어 놓음으로써 계산속도를 향상시키고 저해상도 SLM에 맞춰 lookup table을 적용시키는 방법을 개발하였다. 그리고 이미 성공한 정지영상을 연속 디스프레이하여 동영상으로 표현하였고 스캐너를 이용하여 3개의 동영상을 분리하여 동시에 디스프레이하는 데 성공하였다.
