The objective of this study was to develop and investigate the effects of flipped learning class model on aviation tourism-majored college students. For this study, the flipped learning class model was developed and twenty-one tourism-majored college students who were 15 women and 6 men in their second grade chosen as the participants. They were asked to study learning material in advance and participate in the classroom activities including group work and presentation for 15 weeks, except mid term and final term period. The data collected consisted of pre and post TOEIC reading practice test results with 100 questionnaires, academic attitude questionnaires and students’ learning logs. The results of this study have been obtained as follows; First, there was academic improvements in 21 students’ reading comprehension ability after 15 weeks. Second, there were significant changes in academic attitude such as confidence and learning motivation as shown in questionnaire responses. In particular, flipped learning class model contributed to boosting the students’ self-confidence. Further studies are needed to look into the effects of flipped learning class model based on the students’s need analysis.

The purpose of this study is to look into the effects of presenting learning portfolios on college students’ academic achievement and academic efficacy. For this study, twelve college students were chosen as the participants and asked to make learning portfolios and to present every other week for one semester. The data collected consisted of pre-and post-TOEIC test results, and academic efficacy questionnaires. The following results have been obtained in this study. First, there was academical improvement in students’ listening and reading comprehension ability after presenting learning portfolios. Second, there were positive changes in academic efficacy as shown in questionnaire responses. In particular, presenting learning portfolios contributed to raising the students’ task difficulty preference, self-regulatory efficacy, and self-confidence toward academic achievement. Further studies are needed to investigate the effect of presenting learning portfolios on larger numbers of participants and over longer periods.

외이도염을 악화시키거나 주위로 파급시킬 수 있는 요인으로는 습기가 많은 환경, 땀을 많이 흘리는 경우, 고온, 피부의 잦은손상, 알레르기, 스트레스, 외상, 세균오염, 피부의 지방제거, 피부의 알칼리성화 등이 있으므로 이러한 원인이 생기지 않도록 주의해야 한다.

Objectives: This study was performed to analyze the trend of acne-relatedexperimental studies in Korean medicine. Methods: We searched 17 articles related with experimental study of acne, publishedKorean medical journals from 2005 to 2014. We classified all articles according tothe journal and checked on the kind of herbs. All articles were categorized intotwo types: cell experimental study and animal experimental study. Results:1. Total 17 papers were searched; 7 articles (41.2%) were published in the Journalof Korean Medical Ophthalmology, Otolaryngology, Dermatology, 4 articles (23.5%)were published in the Journal of Korean Institute of Pharmacopuncture, 3 articles(17.6%) were published in Korean Journal of Oriental Physiology and Pathology,2 articles (11.8%) were published in Korean Journal of Herbology, and 1 article(5.9%) was published in the Journal of Korean Medicine. 2. Total 17 kind of herbs were used in the studies; 10 articles (58.8%) used singleherb, 7 articles (41.2%) used complex herbs. 3. Total 17 articles were categorized 2 types; 16 cell experimental studies (94.1%),1 animal experimental study (5.9%). 4. Experimental researches were mainly investigated using Raw 264.7 cell line andP. acnes. The levels of NO, iNOS, TNF-α, PGE, COX-2, IL-1β, IL-6, NF-kB wereanalyzed to confirm of herbs’ antibacterial, anti-inflammatory, antioxidant activity. Conclusions: Searching for natural antibiotics, it is needed to do experimentalstudies continuously, and also needed to diversify the kind herbs and experimentalbacteria.

Multi-sensory design results from sensory design paradigm and image centricism, which stimulates 5 sensation; visual, auditory, haptic, smell and taste sensation when we experience environment. This is helpful for designing outdoor space considering integrated sensation not only visual and auditory sensation as well as for improving visitor's satisfaction. Therefore, this study mainly intended to analyse the multi-sensory preference and the image influence of outdoor leisure space. For these purpose, this study selected 3 leisure spaces around Seoul city; Gwan-ak mountain(the type oriented natural resource), Insa-dong(the type oriented cultural resource) and Seoul land as theme park(the type oriented facility) and a survey was performed with a total of 204 visitors at the above spaces in winter and summer. The results of this study indicate that visual sensation was evaluated most high at 3 outdoor leisure spaces in both winter and summer. Visitors at Gwan-ak mountain and Seoul land prefer visual and haptic sensation, but visitors at Insa-dong prefer visual and haptic sensation in summer, visual and taste sensation in winter. Above all, this study led the designer to consider diverse sensation to access leisure space, especially haptic sense, which can be an effective design strategy to satisfy visitors.

Amenities including natural and sociocultural resources have affected to regional economy development and income distribution. This study intends to analyze the correlation of natural amenities and sociocultural amenities, and clarify the influence between regional economy indicators and diverse amenities using OLS, SLM and SEM. For these purposes, this study chooses 17 natural and sociocultural amenities based on the literature reviews, and collects the statistical data of these amenities. The spatial analysis unit of this study is nationwide 146 Si and Gun except Gu areas of metropolitan city. The main results of this study show that the of SLM and SEM are higher than OLS because natural and sociocultural amenities are relevant to regional spaces and have spatial autocorrelation. In addition, both natural and sociocultural amenities have affected to the regional economy, therefore the policy makers of regions should adopt both amenities in order to boost the regional economy. In conclusion, it is suggested that further researches need to use additional spatial regression models considering diverse amenity resources.

개인적 거리는 동시대 도시민들의 개인적 공간과 영역성, 사회심리적 수용력에 영향을 미치는 환경심리학의 기초개념 중 하나이다. 따라서 본 연구는 대표 조경공간 중 하나인 도시공원을 대상으로, 국내 최초로 벤치이용자들의 이용행태 및 개인적 거리를 분석하고자 한다. 이를 위해 본 연구는 여의도 공원의 벤치 이용자들을 대상으로 Blind observation과 Pictorial analysis를 도입하여 연구를 진행하였다. 주요 연구결과, 남성과 여성그룹의 경우 평균 개인적 거리가 47.5cm로 가장 짧았고, 여성 집단의 경우 53.2cm, 남성집단의 경우 70.3cm로 나타났다. 이러한 연구결과는 이전 서양인들을 대상으로 한 개인적 거리 연구들을 대부분 지지하지만, 일부의 경우 한국인이 개인적 공간과 영역성이 더 좁을 수 있음을 시사한다. Personal distance is one of the basic and important concepts in the field of Environmental Psychology in influencing personal space, visible or invisible territoriality and psychological carrying capacity of contemporary urban dwellers. This study aims to analyze the bench users' behaviour and personal distances in urban parks for the first time in Korea, one of the representative landscape spaces in urban areas. For these purposes, this study has adopted a blind observation and pictorial analysis for bench users in Yeouido Park in Seoul. The main results of this study show that the average interpersonal distance between female and male(intimate relationship) is 47.5cm, the distance between female and female is 53.2cm, and the distance between male and male is 70.3cm. These results mostly support the previous western study results, but the interpersonal space and territoriality of Koreans in urban parks may be smaller than that for western societies.

Graphene, charcoal, ZnO, and ZnS/BiOX (X = Cl, Br, and I) hybrid microspheres for photocatalytic simulated real mixed dye treatments

윤희정,손영구,최영인,장의순 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.32 No.-

Graphene, charcoal, ZnO, and ZnS/BiOX (X = Cl, Br, and I) hybrid microspheres were synthesized for usein the photocatalytic treatment of a mixed dye of MO (methyl orange), RhB (rhodamine B), and MB(methylene blue) solution. The dye degradation rate was generally observed in the order ofRhB < MB < MO. The order became MB < RhB < MO for ZnO/BiOI and ZnS/BiOI. The catalysts hybridizedwith BiOI generally showed superior adsorption capacity to those of the materials hybridized with BiOClor BiOBr. The 10 mol% ZnO/BiOI and ZnS/BiOI showed selectivity for MB adsorption in the mixed dye.
