  • 본 연구에서는 건조방법에 따른 고춧가루의 품질 변화를 비교하기 위하여 한 가지 품종의 고추를 PE House 건조, 열풍건조, 원적외선 방법을 이용하여 건조한 다음, 건조조건별로 고춧가루의 수분함량 변화, pH, ASTA value 및 capsaicinoids와 vitamin C의 함량을 조사하였다. 건조 후 고춧가루의 수분함량은 12.05~14.01% 함유한 것으로 나타났으며, pH는 건조 전 생고추인 4.93보다 다소 높은 5.00~5.54를 나타내었다. 고춧가루의 매운맛을 나타내는 총 capsaicinoids의 capsaicinoids의 함량은 PE House 건조에서 224.40 mg/100 g으로 가장 높게 나타났으며, 열풍 $70^{\circ}C$ 건조에서 191.87 mg/100g으로 가장 낮게 나타났다. 하지만 건조방법에 따른 capsaicinoids 함량이 유의적 차이를 보이지 않았기 때문에, 매운맛 함량의 변화는 큰 차이를 나타내지 않았다. 고춧가루의 대표적 항산화제인 vitamin C 함량은 다른 건조방법 및 조건에 비해 PE House, 열풍 $60^{\circ}C$과 원적외선 $60^{\circ}C$에서 596.60~648.31 mg/100 g으로 높은 수준의 함량을 나타내었다. 소비자가 고춧가루를 선택하는데 중요한 요소로 작용하는 ASTA value는 126.68~156.77로 건조방법 및 조건에 따른 유의적 차이를 나타내지 않았다. 따라서 고추의 건조방법 및 조건을 낮은 온도 조건에서의 열풍, 원적외선 건조방법으로 결정한다면 고춧가루의 vitamin C의 손실을 최소화하고 PE House 건조에 비해 신속하며 오염을 예방하는 고품질의 고춧가루 제품을 생산할 수 있을 것으로 생각된다.

  • Indoor air quality is the dominant contributor to total personal exposure because most people spend a majority of their time indoors. The purposes of this study were to evaluate the alternative method for improvement of indoor air quality in house after coating titanium dioxide ($TiO_2$) photocatalyst for interior part of the house using nitrogen dioxide ($NO_2$) multiple measurements. To evaluate the alternative method in indoor environment, daily indoor and outdoor $NO_2$ concentrations of an apartment and a detached house were daily measured for consecutive 21 days in winter and summer, respectively, Another daily 21 measurements were carried out after $TiO_2$ coating on wall paper of interior part in houses. All $NO_2$ concentrations were measured by passive filter badges. Indoor air quality models using mass balance are useful tool to quantify the relationship between indoor air pollution levels, ambient concentrations, and explanatory variables. Using a mass balance model and linear regression analysis, penetration factor (ventilation rate divided by sum of ventilation rate and decay rate) and source strength factor (emission rate divided by sum of ventilation rate and decay rate) were calculated. Subsequently, the decay constants were estimated. In this study. magnitude of improvement of indoor air quality could be evaluated by decay constant.

  • For the past years, Korean Housing policy have been focused on quantity rather then quality, when they provide housing. Focusing great quantity on housing led monolithic and standardized house forms in limited area. Most of our traditional residental environment, which made Koreans to communicate with neighbors, disappeared from the result of providing great quantity on housing. However, the increase of the income and standard of living, changed people's view. People start to demand for the place which is commodious and comfortable to live. Moreover, more leisure time caused people to communicate with their neighbors. To meet the demands of new forms of housing, they started to provide a community space to increase sense of belonging and community spirit for the residents in apartment house. The forms of past house which is defined by uniformity is delivered from rational thoughts. People can get emotional satisfaction from Community space because it provides opportunity of communicating and increase community spirit. This research is to classify the emotional expression in Community space and analyze the elements that is expressed in community space of apartment house.

  • In order to produce the high quality of dried-ear mushroom, various drying methods such as hot-air drying at $40{\sim}80^{\circ}C$, freeze drying and drying in vinyl house were carried out. Drying hours of hot-air drying, freeze drying and drying in vinyl house were 12.5~21.5, 36.0 and 72.0 hrs, respectively. Vitamin $D_2$ content of sample was the highest as $6.77{\mu}g/g$ DW in drying in vinyl house and then followed by freeze drying as $5.90{\mu}g/g$ DW and hot-air drying as $1.89{\sim}5.01{\mu}g/g$ DW. After dry, external appearance and color of mushrooms applied hot-air drying and drying in vinyl house were better than freeze-dried one. After rehydration, water uptake of sample in drying in vinyl house and hot-air drying at $50{\sim}60^{\circ}C$ were 17.8 and 19.3~21.0 times, respectively. The methods of drying in vinyl house and hot-air drying at $50{\sim}60^{\circ}C$ also led to high hardness, good shape and resilience. As the results of production of dried-ear mushroom with high quality, we suggest that the best method for drying is the drying in vinyl house due to not only high vitamin $D_2$ content, good external appearance and color after drying but also high hardness and good shape after rehydration.

  • The purpose of this study was to analyze the general characteristics of coffee house consumers as well as the importance and satisfaction of selection attributes of specialty coffee houses according to length of coffee education period. Applicants in the Gwangju and Jeonnam area who had finished their Barista 2 grade certificate examination participated in a survey on March 12, 2011. Further, university students living in Gwangju participated as subjects who had never experienced coffee education from March 15 to March 31, 2011. Two-hundred and one subjects participated in the survey, and 184 questionnaires were used for analysis. Regardless of coffee education experience, quality of coffee was important, but higher educated subjects showed the lowest satisfaction of coffee from a coffee house (p<0.01) in terms of attributes such as freshness of coffee beans (p<0.01) and overall taste (p<0.01). Further, subjects who received no or little education demonstrated high correlation between importance/satisfaction of 'brand' and 'employee' compared to subjects who studied more than 2 semesters. These results provide future coffee house entrepreneurs and baristas with market information and marketing strategies for understanding customers' coffee house selection attributes.
