In this study, the beauty industry was identified as a strategic sector with potential to lead the growth of the global economy in the 21st century. Therefore, Medical Aesthetic and Beauty Fashion have prospects to drive the long-term development and growth of the tourism industry into the next generation. Combining the two sectors as a strategy for generating growth of the tourism industry is presently being suggested. The results of the current study suggests various implications. The age classification factor of 20, 30, 40, 50 and 60 was identified as relevant to medical aesthetic and beauty fashion because of differences in perception among these age groups. Appropriate marketing strategies are therefore needed for each target segment. Furthermore, the selection or expenditure on beauty products was based on monthly income categories of 1,000,000 won, 1,000,000-2,000,000 won, 4,000,000-5,000,000 won or less. These groups were found to differ in their selection of beauty products. In addition, under 2,000,000-3,000,000 won, 3,000,000-4,000,000 won, and less than 5,000,000 won monthly income groups were included as another factor in the study. The price of a variety of configurable options, such as product development and effective marketing strategies, are therefore necessary to derive expected returns. The two factors influencing participation in the beauty and tourism industries showed positive (+) effects.

새집증후군 유발 벤젠가스 흡착에 미치는 활성탄소섬유의 함산소불소화 영향
임형순 ( Hyung Soon Lim ),김민지 ( Min-ji Kim ),공은영 ( Eun Young Kong ),정진도 ( Jin-do Jeong ),이영석 ( Young-seak Lee ) 한국공업화학회 2018 공업화학 Vol.29 No.3
본 연구에서는 새집증후군 원인가스 중 하나인 벤젠 가스 흡착특성을 향상시키기 위하여 활성탄소섬유에 함산소불소화 처리를 실시하였다. 함산소불소화 처리된 활성탄소섬유 표면특성 및 기공특성은 X-선광전자분광기(XPS)와 Brunauer-Emmett-Teller (BET) 분석을 통해 확인하였으며, 벤젠 가스 흡착 특성은 가스크로마토그래피(GC)로 평가하였다. XPS 결과로부터 불소분압이 증가함에 따라 활성탄소섬유 표면의 불소관능기가 증가함을 알 수 있었다. 함산소불소화 처리 후 모든 샘플의 비표면적은 감소하였으나, 불소 분압이 0.1 bar일 때 그 미세기공 부피비가 증가하였다. 함산소불소화 처리된 활성탄소섬유는 11 h 동안 100 ppm의 벤젠 가스를 모두 흡착하였으며, 이는 미처리 활성탄소섬유와 비교하여 벤젠 가스 흡착효율이 약 2배 향상됨을 알 수 있었다. In this study, activated carbon fibers (ACFs) were treated by oxy-fluorination to improve the adsorption property of benzene gas, one of the gases causing sick house syndrome. Surface properties and pore characteristics of oxyfluorinated activated carbon fibers were confirmed by X-ray photoelectron Spectroscopy (XPS) and Brunauer-Emmett-Teller (BET), and adsorption properties of benzene gas were evaluated by gas chromatography (GC). As a result of XPS data, it was confirmed that the fluorine functional groups on activated carbon fibers surface increased with increasing the fluorine partial pressure. The specific surface area of all samples decreased after the oxyfluorination treatment, but the micropore volume ratio increased when the fluorine partial pressure was at 0.1 bar. The oxyfluorinated activated carbon fibers adsorbed 100 ppm benzene gas for an 11 h, it was found that the adsorption efficiency of benzene gas was improved about twice as much as that of untreated ones.
