Background: Thoracoscopic R3 sympathicotomy can effectively treat palmar hyperhidrosis. Here, we evaluated post-operative outcomes of patients receiving a thoracoscopic R3 sympathicotomy due to palmar hyperhidrosis. Material and Method: From January 2001 to December 2006, 225 patients were treated with a R3 sympathicotomy, and follow up was completed for 200 patients, with an average follow up period of 51.7 ($11{\sim}80$) months. We measured postoperative hand sweating according to four grades; dry (grade 1), proper (grade 2), light sweating (grade 3), heavy sweating (grade 4) and evaluated patient satisfaction using 4 grades: very good (grade 0), good (grade1), regular (grade 2), and deficient (grade 3). Result: There were no differences in clinical parameters between the compensatory sweating group and the non-compensatory sweating group. There was a 83.5% compensatory sweating rate. The degree of compensatory sweating related to the patient's body mass index and was influenced by the season, environmental temperature, and emotional stress. Conclusion: The satisfaction rate was 61.5%, and the degree of satisfaction related to the development of compensatory sweating. Therefore, reducing compensatory sweating would increase patient satisfaction with R3 sympathicotomies.

In this study, the influence of classroom smells (foot odor, hair smell, sour smell, and sweat smell) of male high school and sweat smell and the offensive odor substance (ammonia and butyric acid) on the electroencephalography (EEG) activities of 20 female volunteers, ranging in age from 30 to 50 were studied. The representative response of brainwave index by these smells stimuli was most pronounced on temporal lobes among the brain lobes. By comparison with background EEG activities on temporal lobes, the smells reduced the relative alpha band power (0.04~0.13) and increased the relative beta band power (0.02~0.06) and the relative gamma band power (0.03~0.09). The alpha wave was deactivated, high beta (18~30Hz) and gamma (30~50Hz) waves were remarkably activated. The order of EEG fluctuation caused by the smell stimulus is as follows; hair smell > butyric acid > foot odor, sour smell > ammonia > sweat smell. It means that the classroom smells cause an excessive brain arousal and straining and may be reducing one's attention and learning ability.

We identify the enhancement effects of zinc chloride and liquid nitrogen on low quality ninhydrin-developed fingerprint and we wanted to find out another cooling methods available for ninhydrin/Zn fingerprint enhancement besides the liquid nitrogen, which is hard to access. Artificial sweat was used to make the same level of fingerprints, and fingerprints developed by each technique were evaluated by SWGFAST standard and compared the average score and standard deviation. As a result of the experiment, ninhydrin/Zn-liquid nitrogen got 3.2 and 3.3 as average scores that enough to identify an individual such as 1,2-IND/Zn or DFO. Also, experiments using dry ice instead of liquid nitrogen as a way of the ninhydrin/Zn-developed fingerprints enhancement resulted in 3.0 and 2.9 as average scores, therefore, it was confirmed that dry ice is also a sufficient cooling method to be considered in practice in the field of forensic science.

Once powder base makeup products are applied to the skin, the products are formed a film and attached on the skin for 8 to 12 hours. The makeup film is deformed by secretions such as sweat and sebum secreted from the skin. Thus, durability of the film is an important quality factor in the makeup and its evaluation is also important. In this study, characteristics of the semi-finished powder products such as water absorption, oil absorption, water repellent and oil repellent were evaluated in a number of ways. Also, simple methods, which are not affected by evaluation conditions such as a difference between sweat and sebum secretion, temperature and humidity, were examined to predict the durability of the products. We measured water absorption, oil absorption, water repellent and oil-repellent properties of semifinished product by tablet, capillary and dipping method and then compared with the data of color difference meter and ROBO skin analyzer. Results showed that the durability of powder base makeup products was associated with more oil absorption and water-repellent characteristics than water absorption and oil-repellent. Oil absorption characteristics by tablet and capillary method and water-repellent characteristics by dipping method provides a simple and quick method to precdict the durability of the makeup products.

Sensor and optical properties have become critical features in powder foundation. The flaky barium sulfate powder shows good smooth texture, adhesion and natural looking characteristics. However, it has limitations abilities in UV shielding, hiding and blooming effect. Thus we adopt TiO$_2$ that has excellent hiding power and blooming effect as well as UV shielding ability, but TiO$_2$ has still intrinsic problems in dispersion and texture. To overcome this disadvantages, the barium sulfate/TiO$_2$/dimethicone composite powder was prepared. The flaky barium sulfate powder was coated with TiO$_2$ in nanoscale and followed by coated with dimethicone. When this surface-modified powder was applied for make-up cosmetics, especially in powder foundation, the powder gave powder foundation more good characteristics than the original flaky barium sulfate, Ti02 powder, dimethicone in abovementioned optical and sensory properties. To characterize the distinctive features of this surface-modified powder, we measured its characteristics with UV in vitro tester, hiding powder test method, goniophotometer, consumer panel test and so on.

배경: 다한증의 치료에 있어서 흉강경을 이용한 교감신경절제술의 시술 빈도가 급증하고 있다. 그러나 액와부 다한증의 경우 수장부나 안면 두부다한증에 비하여 절제범위가 광범위하여 이에 따른 보상성 다한증 및 기타 합병증의 발생의 높고 액취증이 동반되어있는 경우 장기적인 만족도가 낮아서 크게 각광 받지 못해왔다. 대상 및 방법: 본 교실에서는 1997년 3월부터 1999년 4월까지 45례의 액와부 다한증 환자에서 2 mm 흉강내시경을 이용하여 흉부교감신경절제술 또는 잘단술을 시행하였다. 남자 28례 여자 17례로 평균연령은 28(13-46세) 였고 평균추적기간은 10개월(1-24)이었다. 24례가 액와부에만 국한된 과도발한을 호소 하였고 2례에서 수술 전 심한 액취증이 동반되어있었다. 21례의 T3,4 교감신경절제술, 20례의 T2,4 교감신경단술 그리고 4례의 T4 교감신경절제수을 시행하여 즉각적인 증상치유효과 보상성 다한증 및 장기적 만족도를 비교 분석하였다. 중등도 이상의 흉막유착으로 5mm 내시경이 필요했던 2례을 제외한 전 환자에서 2mm 트로카 2개를 사용하여 수술을 하였다 결과: 평균수술시간은 T3,4 교감신경절제술이 46.2$\pm$11분 T2, 4 교감신경절단술이 32.5$\pm$23분 T4 교감신경절제술이 53.8$\pm$18분이 소요되었고 수술직후의 효과는 T3,4 교감신경절제술과 T2,4 교감신경절단술에서 '전혀땀이 나지 않는다'가 17례(81%) 와 12례(60%) '수술전보다 감소했으나 약간땀이 난다'가 4례(19%) 와 8례(40%) 로 모든 환자에서 효과가 있었으나 T4 교감신경절제술은 4례중3례(75%)에서 전혀 효과가 없었다. 보상성 다한증은 T3,4교감신경절제술과 T2,4 교감신경절단술에서 각각 67%, 60%로 나타났고 생활에 불편을 줄 정도의 심한경우는 10% 5%에 불과했으며 장기적인 만족도는 T3,4 교감신경절제술이 86% T2,4 교감신경절단술이 89%로 나타나 높은 성공률을 보았다 결론 : 액와부다한증의 치료에 있어서 T3,4 교감신경절제술과 T2,4교감신경절단술은 증상치유효과가 높고 절제범위의 제한에 따른 보상성 다한증의 감소로 장기적 만족도가 우수한 효과적인 방법이다. 액취증이 동반된 경우 이에대한 충분한사전 설명과 원인 감별후 적절한 보조요법을 병행함으로써 환자의 만족도를 높힐수 있다고 본다.

발수가공은 섬유표면에 낮은 표면에너지 물질을 도포하여 섬유제품에 적심 저항성을 부여하는 것으로 일반적인 방법으로는 불소계 고분자 물질을 포함한 가공제액을 부여하고 열에너지원을 사용하여 섬유 표면에 경화하여 고착시키고 처리온도는 $150{\sim}170^{\circ}C$의 범위에서 수 분 처리하지만 처리시간을 증가하면 섬유에 황변을 일으킬 수 있고 직물의 한 면에만 발수성을 구현하기가 어렵다. 피부와 접촉하는 부위에서의 불필요한 발수성은 땀 흡수저하, 알러지 발생 우려 등 쾌적성 저하 요인이 될수 있어 스포츠, 레저 의류 분야에서는 섬유제품의 일면만을 발수처리 하는 가공이 필요되어진다. 편면 발수가공을 위한 선행기술로는 상하 중 하나의 롤러에만 발수제를 묻혀 섬유제품의 일면에만 발수가공을 하는 것과 분사기로 발수제를 섬유제품의 일면에 도포하는 것 등이 있다. 하지만 일면에 처리된 발수제가 반대면으로 침투하거나 균일한 발수처리가 되지 않는 등의 문제점이 있고 발수제의 농도증가 및 증점제를 사용하여 점도를 증가시켜야하기 때문에 발수처리의 균일성 및 내구성 있는 편면발수공정이 어려운 단점이 있다. 본 연구에서는 UV경화가 가능한 불소계 발수제와 물에 용해되는 광개시제가 첨가된 수용액을 PET직물에 패딩하고 UV로 경화하여 양면 모두 발수성을 부여한 후 UV조사로 표면개질하여 표면친수성을 증가시켜 양 면의 발수성을 조절하였다.

운동화 안감으로 사용되는 부드러운 천연 가죽의 내부 구조 및 쾌적성과 유사하게 개발한 3종류의 편성포에 관하여 수분 전달 능력을 비교 측정하였다. 편성포 표면에 이면으로 땀액의 이동성을 측정하기 위하여 새로운 실험 절차를 고안하여 측정한 결과, 편성포에 가한 압력은 수분 이동 능력에 영향을 미치지 않았다. 그러나 편성포의 기모가 있는 표면과 기모가 없는 이면의 수분 이동 능력이 달랐고, 3종류중 한 편성포에서는 표면의 기모는 수분전달을 저하시켰다. 표면은 기모, 이면은 평편조직으로 두껍고 무거운 편성포의 수분전달이 가장 좋았고 이 편성포와 같은 조직이면서 두께와 중량이 적은 편성포는 수분전달이 감소되었다. 수분이동 능력을 향상시키기 위하여 편성포의 섬유와 구조를 고려할 때 기모량은 중간 정도이고 기모된 표면을 수분에 접하도록 하는 것이 바람직하다. 이렇게 함으로서 더 효과적인 수분 이동이 이루어져서 피부 표면에서 땀증발이 좋았다. 이 연구에 사용된 실험 방법은 편성포의 수분 이동 체계에 관한 이해 증진에 기여할 수 있다고 본다.
