최재일,전용균 한국웰니스학회 2024 한국웰니스학회지 Vol.19 No.3

이 연구는 비만 유·무의 차이가 유산소운동 시 Irisin, Myonectin의 일시적, 장기적 변화에 미치는 영향을 규명하기 위해 실시되었다. 20대 성인 남성을 대상으로 실시되었으며 일반집단(NOG, n=16)의 경우 체지방률 20% 이하인 남성 16명, 비만집단(OG, n=16)의 경우 체지방률 25% 이상인 남성 16명을 선정하였다. 반복측정 분산분석을 실시한 결과 일시적 유산소운동(70% VO2R)시 irisin과 myonectin 발현 수준이 NOG에서 안정시에 비해 운동종료 30분 후 유의하게 증가하였지만 OG에서는 유의한 차이가 나타나지 않았다. 일시적 유산소 운동 실험 종료 후 모든 대상자들을 일반운동집단(NOAG, n=8), 일반통제집단(NOCG, n=8), 비만운동집단(OAG, n=8), 비만통제집단(OCG, n=8)으로 재분류하여 8주간 유산소 운동을 실시하였다. 8주 후 일반집단에서는 체지방률이 NOAG에서 유의하게 감소한 것으로 나타났다. 또한 NOAG에서 안정시 irisin 및 myonectin 수준이 8주 후 유의하게 증가한 것으로 나타났다. 비만집단의 경우 체중과 체지방률이 OAG에서 8주 후 유의하게 감소한 것으로 나타났고, 근육량은 유의하게 증가한 것으로 나타났다. 또한 OAG에서 안정시 irisin 및 myonectin 수준이 8주 후 유의하게 증가한 것으로 나타났다. 종합해보면 장기적인 유산소운동을 통해 irisin 및 myonectin 발현 수준이 증가한 것으로 나타났는데, 이는 체중, 체지방률 감소 및 근육량 증가에 기인한 것으로 판단된다. This study was conducted to investigate the effects of obesity on the short-term and long-term changes in Irisin and Myonectin levels during aerobic exercise. The study involved adult men in their 20s, with 16 men selected for the non-obese men group (NOG, n=16) having a body fat percentage of 20% or less, and 16 men selected for the obese men group (OG, n=16) having a body fat percentage of 25% or more. The results of repeated measures ANOVA showed that during short-term aerobic exercise (70% VO2R), the levels of Irisin and Myonectin significantly increased 30 minutes after exercise in the NOG compared to the resting state, while no significant differences were observed in the OG.. After the short-term aerobic exercise experiment, all participants were reclassified into a normal-weight exercise group (NOAG, n=8), a non-obese men control group (NOCG, n=8), an obese men exercise group (OAG, n=8), and an obese men control group (OCG, n=8), and they underwent an 8-week aerobic exercise program. After 8 weeks, there was a significant reduction in body fat percentage in the NOAG within the normal-weight group. Additionally, the levels of Irisin and Myonectin at rest significantly increased in the NOAG after 8 weeks. In the obese group, both body weight and body fat percentage significantly decreased in the OAG after 8 weeks, while muscle mass significantly increased. Furthermore, the levels of Irisin and Myonectin at rest significantly increased in the OAG after 8 weeks. In summary, the study found that long-term aerobic exercise led to increased levels of Irisin and Myonectin, which is believed to be due to the reduction in body weight and body fat percentage, as well as the increase in muscle mass.

Purpose: In accordance with the increasing number of accidents caused by various reasons and recently developed fine diagnostic skills, the incidence of orbital blow-out fracture cases is increasing. As it causes complications,such as diplopia and enophthalmos, surgical reduction is commonly required. This article reports a retrospective series of 5 blow-out fracture cases that had unusual nerve injuries after reduction operations. We represents the clinical experiences about treatment process and follow-up. Methods: From January 2000 to August 2009, we treated total 705 blow-out fracture patients. Among them, there were 5 patients (0.71%) who suffered from postoperative neurologic complications. In all patients, the surgery was performed with open reduction with insertion of Medpor . Clinical symptoms and signs were a little different from each other. Results: In case 1, the diagnosis was oculomotor nerve palsy. The diagnosis of the case 2 was superior orbital fissure syndrome, case 3 was abducens nerve palsy, and case 4 was idiopathic supraorbital nerve injury. The last case 5 was diagnosed as optic neuropathy. Most of the causes were extended fracture, especially accompanied with medial and inferomedial orbital blow-out fracture. Extensive dissection and eyeball swelling, and over-retraction by assistants were also one of the causes. Immediately,we performed reexploration procedure to remove hematomas, decompress and check the incarceration. After that, we checked VEP (visual evoked potential), visual field test, electromyogram. With ophthalmologic test and followup CT, we can rule out the orbital apex syndrome. We gave Salon (methylprednisolone, Hanlim pharmaceuticals) 500mg twice a day for 3 days and let them bed rest. After that, we were tapering the high dose steroid with Methylon (methylprednisolon 4 mg, Kunwha pharmaceuticals) 20 mg three times a day. Usually, it takes 1.2 months to recover from the nerve injury. Conclusion: According to the extent of nerve injury after the surgery of orbital blow-out fracture, the clinical symptoms were different. The most important point is to decide quickly whether the optic nerve injury occurred or not. Therefore,it is necess is to diagnose the nerve injury immediately,perform reexploration for decompression and use corticosteroid adequately. In other words, the early diagnosis and treatment is most important. (J Korean Cleft Palate Craniofac Assoc 11: 28, 2010)

In the 21st century, the concept of food is showing different pattern from that of the past. If there was a time when it was understood as a physiological desire to fill one's stomach, now, it is approaching the area of nutrition, health, beauty, culture and art. Cooking, which started as humans discovered fire, has been developed in various methods and sorts according to time and space with the development of agriculture and bowls. Also, as the economy grew, it became to regard taste as important, and the factors such as joy for the food choice, the passion of the people preparing and decorating cuisine, and the artistic sublimation of table combined, unique cooking and tableware developed in each country. Japanese people talk about food as "Look with eyes and eat the eyes." The eating culture of Japan orients the best food as making use of unique taste, scent and color of each ingredient, and have used the utensils, cuisines, bowls. They have developed food as an art work and it has been placed as a culture. They are to place the food in the bowl nicely and attach importance to seasonal sense in taste and decoration. Japanese epicures talk about the eating culture as the same expressionist art with music. That is, like the music, many notes of sound are coordinated and a song is completed as melody, rhythm, and harmony, they think eating culture as an art culture that moves the people by creating and producing tasty cuisines and eating life as coordinating ingredients, cooking skill and utensils. 1)Food has 3 kinds of functions. Influential function, physiological control function and sensory function are those. These 3 functions have been attached importance to different functions in proportion to the economic level of that country and among them, sensory function is talking about the visible taste. It has been placed as a culture called tableware by creating food as an artistic work. The action eating seems similar but the quality of life differs according to when, where, with whom and how one eats. Even if it's the same food, according to what kind of bowl do they eat with differs the situation greatly. The table with much devotion changes and pleases people. 21세기 식(食)에 대한 개념은 과거의 것과는 다른 양상을 띠고 있다. 단순히 배를 채우기 위한 생리적 욕구로서의 이해되던 시절이 있었다면 현재는 영양소, 건강, 미용, 문화, 예술의 영역까지 포함하고 있다. 인류가 불을 발견하면서 시작된 조리는 농업과 그릇의 개발과 더불어 때와 장소에 따라 매우 다양한 방법과 종류로 발달되어왔다. 또한 경제가 성장하면서 미각을 중시하였고, 음식 선택에 대한 기쁨, 요리를 꾸미고 준비하는 사람들의 열정, 식탁에 대한 예술적 승화 등의 요인들이 조합되어 각 나라마다 독특한 조리방법과 테이블웨어가 발전되어왔다. 본 논고에서는 일본의 예를 들어 테이블웨어의 현황을 살펴보고자한다. 일본인(日本人)들은 흔히 음식을 빗대어 “눈으로 보고 눈으로 먹는다.”라고 이야기한다. 일본의 식문화는 각 재료의 고유한 맛과 향, 색을 살리는 것을 최고의 음식으로 지향하며, 조리기구와 조리법, 식기를 이용해 하나의 작품으로서 음식을 창조 발달시켜 문화로 자리 잡았다. 음식을 그릇에 보기 좋게 담고, 맛과 장식에 있어서 계절감을 중요하게 여기는 특징이 있다. 일본의 미식가들은 음식 문화를 음악과 동일한 표현예술이라고 이야기한다. 즉, 음악에서 여러 가지 음색의 소리를 코디네이터 하여 멜로디, 리듬, 하모니로써 하나의 곡이 완성되는 것처럼, 식문화는 식재료와 조리기술, 도구를 코디네이션(Coordination) 하여 맛있는 요리와 식생활을 창작, 연출함으로써 사람들의 감동을 이끌어내는 예술문화의 하나라고 생각하는 것이다. 음식은 세 가지 기능을 가지고 있다. 영양적 기능, 생체조절기능, 감각적기능이 그것이다. 이 세 가지 기능은 그 나라의 경제수준에 비례하여 각각 다른 기능을 중시하고 있으며 그중 감각적 기능은 보이는 맛을 이야기하는 것이다. 하나의 작품으로서 음식을 창조 발달시켜 테이블웨어(Tableware)라는 문화로 자리 잡아온 것이다. 먹는다는 행위는 비슷하게 보여도 언제 어디서 누구와 어떻게 먹느냐에 따라 달라진다. 같은 음식이라도 어떠한 용기에 담아 먹느냐에 따라서 그 차이는 더욱 크다. 정성이 들어간 식탁은 사람들을 감동시키고 변화하게 만든다.

최재일,손대구 대한미용성형외과학회 2021 Archives of Aesthetic Plastic Surgery Vol.27 No.2

Background The objective of this study was to determine the outcome of serial excisions of congenital nevi involving the face and extremities and to calculate changes in the area and length of the nevi. Methods Data from 18 patients with congenital nevi who underwent serial excisions from 2005 to 2017 were retrospectively reviewed. There were 12 congenital nevi involving the face and six involving the extremities. Two serial excisions were performed in all cases. The final diagnosis was confirmed by histology. Postoperative outcomes were analyzed photogrammetrically. The clinical outcomes were analyzed through ordinary scales. Results The mean age of patients and the median area, length, and width of congenital nevi on the face and extremities were 9.4 and 15.2 years, 189.8 and 487.8 mm2 , 21.1 and 35.0 mm, and 13.2 and 19.6 mm, respectively. After the first operation, photogrammetric analysis showed a 64.6% reduction in the area of facial nevi and a 68.1% reduction for nevi on the extremities. The final scar length increased by 62.8% for the face and 73% for the extremities compared to before surgery. A clinical assessment demonstrated excellent results for the removal of the congenital nevi, without any deformation of the surrounding structures, and good final scar quality. Conclusions This study will contribute to the prediction of results of each stage when serial excision is required.

Purpose: Many facial burn patients suffer from hyperpigmentation and its treatment has been challenging. Vitamin C (ascorbic acid) has important physiologic effects on skin, including inhibition of melanogenesis, promotion of collagen biosynthesis, prevention of free radical formation,and acceleration on wound healing. The purpose of this study is to evaluate the effectiveness of Vitamin C iontophoresis for the treatment of postburn hyperpigmentation. Methods: The authors performed a retrospective analysis of 93 patients who were admitted for the treatment of facial burn from February 2008 through February 2010. Among them, 51 patients were treated with Vitamin C iontophoresis to control postburn hyperpigmentation and 42patients were not. Experimental group was chosen 20 of 51 patients who had been treated with Vitamin C iontophoresis and had normal facial skin on the comparable contralateral aesthetic unit. Control group was chosen 20 of 42patients who were not treated with Vitamin C iontophoresis and had also contralateral normal aesthetic unit. The resulting color of 20 patients who were treated with Vitamin C iontophoresis was compared with the color of the contralateral normal facial skin using a digital scale color analysis. Results were analyzed with Wilcoxon signed rank test. Results: The analysis revealed significant improvement of hyperpigmentation in the experimental group compared to control group. The difference of intial value and the value in 6 months showed significant change. Mean (Δ^initial-Δ^6month) of experimental group was 11.61 and control group was 7.23. Thus, the difference between the experimental group and the control group was 4.38. Therefore, Vitamin C iontophoresis revealed significant improvement of hyperpigmentation in the experimental group compared with control group. Conclusion: Vitamin C iontophoresis is an effective treatment modality for postburn hyperpigmentation.
