  • Based on an ecological monitoring in a Korean stream (Gapyeong), Habitat Suitability Index (HSI) of nine fish species was developed for three physical habitat factors : current velocity, water depth and substrate. The species were chosen based on their abundance and frequency in the fish community of the Gapyeong stream. The Weibull model was used as the probability density function to analyze the distribution and number of each fish species according to the three identified physical factors, which showed good results. This HSI equation has advantages because it statistically expresses habitat preferences of fish species simply and clearly. From that, we can quantitatively deduce the central tendency and variation of environmental factors for fish distribution. The selected fish species showed different preferences for each habitat factor respectively. Although there are some exceptions, the distribution and abundance of individual species of nektonic fish (Zacco koreanus, Zacco platypus, Microphysogobio longidorsalis and Pungtungia herzi) were positively skewed to deep water and fine substrate while riffle-benthic fish (Koreocobitis rotundicaudata and Coreoleuciscus splendidus) were normally distributed at the shallow and coarse substrate zone. It seems that the species showing the positively skewed distribution to the current, Z. koreanus, Z. platypus, M. longidorsalis and P. herzi have adapted themselves to the fast current and have expanded their niche.

  • The purpose of this research is to empirically validate the IIPS (Interior Image Preference Scale) which is a newly developed visual instrument for evaluating the environmental disposition inherent to individuals especially one's interior image preferences. The questionnaire survey was used. The data were collected from Oct. 10th 1997 to Nov. 14th 1997. The subjects were 399 undergraduate students and 30 professor of Dep. of Interior Design. With respect to content validity and construct validity of IIPS discrimination and similarity structure of scales and characteristics of 12 prototype interior images were examined in comparison with the originals. 429 questionnaires were analyzed using frequency percentage mean and Multi-Dimensional Scales. The major results were as follows (1) All 80 items of IIPS were discriminated by 3 criteria such as Traditionalism·Modernity(TM) Masculinity·Femininty (MF) and Simplicity·Complexity (SC) as expected at the time of the instrument development stage.(2) 12 prototype interior images of the IIPS showed tendency to be accord with descriptors to express them in comparison with the originals (3) All 90 items of IIPS showed a cluster distribution according to the similarity structure of scales. Three subscales of IIPS(e . g. TM MF and SC) were structured pretty well by those 3 dimensions. This research revealed the IIPS to have content validity and construct validity for evaluating of preference of three properties of interior image in empirical research. The IIPS was found to be potential objective tool to measure the interior image preferences.

  • This study investigated residents' preferences for spatial features of sitting areas in assisted living facilities, and provides recommendations for planning sitting areas to support residents' spatial preferences and social interaction. The study participants were 69 residents of eight assisted living facilities (30+ resident capacity), located in south central Texas. A photographic comparison method was used, in which residents were shown 20 matched pairs of photos, with a single feature digitally modified in each pair, and asked to select which environmental representation they preferred. The hypothesized spatial characteristics were identified in practice based literature as those that may encourage usage of sitting areas: viewability, variety, homelikeness, and privacy. Most of the hypothesized features were preferred by participants, with the highest preference found for non-institutional furniture arrangements and naturalness, followed by increasing enclosure and variety of seating. Preference was less significant for domestic cues such as carpeted floors, divided light windows, and boundaries defined by different colored material or columns, possibly due to their physical impairments or preference for visual openness. Participants' level of mobility assistance was significantly related to their preference for some features, such as seating with people-watching capability, and carpeted floors. The findings have implications for facility architects and administrators engaged in resident-oriented spatial planning.

  • With the development of cognitive science and environmental psychology, there have been growing researches and discussions on the relationship between the residential design preferences and personality types. MBTI personality types have been earning popular credibility. MBTI means Myers-Briggs Type Indicator. It is based on Carl Jung's theory of psychological type. This study is based on Myers-Briggs theory to explain residential furnishing preference and explores the relationship between the four bi-polar personality types-Extroversion/Introversion, Sensing/Intuition, Thinking/Perceiving and residential furnishing preference. These tests were conducted to two hundred and twelve adult residents who live in Seoul, Korea. These tests were analyzed several significances by Chi-Square with SPSS for windows software. (E) Extroverted residents prefer layouts for interaction with guests. (I) Introverted residents prefer centripetal layout around the bed. (S) Sensing residents prefer practical and functional layouts. (N) Intuitive residents prefer personal and conceiving layouts. (T) Thinking residents prefer for attribute of space. (F) Feeling residents for familiar conversation. (J) Judging residents prefer systematic and complete layouts. (P) Perceiving residents prefer adaptable and flexible layouts. In conclusion, personality types can have a determining role in preference of residential furnishing layouts. This study suggests that residential designers should take into account clients' personality types prefer effective designing and should provide a variety of alternatives reflecting clients' preferences. This will promote clients' pleasantness and satisfaction in dwelling at home.

  • 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.

  • This research investigates and characterizes lifestyles and housing preferences of Korean-American Baby Boomers in the USA, and proposes future housing design and planning directions to meet their needs. A questionnaire survey was conducted from June to September 2012 examining lifestyles and preferred characteristics of postretirement homes. We targeted Korean-Americans born from 1955 to 1963 in either Korea or the USA who currently reside in New York, Washington DC, Chicago, Dallas, Detroit, Lansing, Grand Rapids, and San Francisco. To analyze the 247 responses, we employed factor analysis, cluster analysis, one-way ANOVA, and crosstabs. Respondents preferred three-bedroom, singlefamily housing types with a size of 26-35 pyong, favoring city outskirts or suburbs over urban areas. Four groups having different lifestyle types were identified: innovators, believers, fashion experiencers, and makers. Housing preference differed depending on lifestyle types. The 'innovator' group desired homes 56 pyong or larger, while the other groups preferred 26-36 pyong. The four lifestyle groups did not show statistically significant differences in most of preferred housing features, community facilities, or indoor environmental characteristics. Each group still showed slightly different preferences in some housing planning characteristics, which future planners can refer to when providing postretirement homes for them.

  • The number of vegans has increased rapidly due to religious and ethical beliefs, environmental concerns, health, etc. Also, as interest in healthy and safe food increases, the demand for organic products or nutrition-enhanced products is increasing. Therefore, this study aimed to investigate the selection attributes and purchasing behavior for protein-fortified and vegan snacks. It is anticipated that the results would find use as basic data for developing protein-fortified snacks for vegans that can meet consumer needs and derive marketing strategies. A survey was conducted on 140 consumers. According to the analysis of their purchase behavior, the number of people who had purchased high-protein snacks and vegan snacks was higher than those who did not have prior experience. The reasons for the purchase of protein fortified snacks included 'meal replacement' at 'offline-convenient store/supermarket'. Vegan snacks were purchased for 'ethical beliefs, health, environment' at 'offline-vegan restaurant, bakery'. Both snacks showed above-normal preferences. However, it is necessary to improve taste and flavor when developing these products as these were the factors that negatively impacted the preferences. The attributes were factorized into the 'showing off factor', 'sensory factor', 'credence factor', and 'functional factor' and the 'sensory factor' was considered the most important.
