The purpose of this study was to investigate(1) the effects of clothing cues of 20s young man in business suits on the perception of occupational suitability in an office setting and (2) the effect of Perceiver's self-monitoring and sex on the perception of occupational suitability formed by the function of clothing cues. The experimental design of this study was between-subjects 23 factorial design. The experimental materials developed for the study were a set of stimuli and a response scale. The stimuli consisted of 8 color photographs of a young man wearing business suits which were manipulated at two levels for each of three clothing cues (suit color, suit style, necktie color). Each one of eight sub-samples included 14 subjects from 2 perceiver groups by sex. The questionaires used to measure perceivers' responses to the stimuli were constructed in 12 five-point likert scale representing occupational suitability and self-Monitoring was measured by the self-Monitoring Scale by Gangestad adn Snyder. The subjects consisted of 224 male and female college students in Seoul. The data was processed by ANOVA and MCA(Multiple Classification Analysis). The result were as follows: (1) The Clothing cues of young man in business suits(suit color, suit style) partially influenced the occupational suitability. (2) The perception of occupational suitability formed by the clothing cues of a young man in business suits was partially influenced by the perceiver's self-monitoring and sex. Female high self-monitoring group were more affected by the clothing cues than any other groups.

With the rapid change of rural communities and increasing desire for social welfare, the demand for the quality of public spaces and facilities is increasing. However, inefficient location of rural public space and facility has caused problems such as economic inefficiency, inconvenient accessibility, environmental pollution, unsustainable energy use, and disturbance of visual landscape. This study aims to evaluate suitability of public spaces and facilities in three types of rural village: rural downtown village, rural clustered village, and individual village. As a way to measure the suitability of public spaces and facilities, we assessed indicators of suitability in terms of accessibility, usability, biophysical environment, and sustainable management. To evaluate the accessibility, we applied indicators such as distance from residential areas, public transit, market and public facilities. For the evaluation of biophysical environment, we applied indicators such as slope, elevation, aspect, and occurrence of natural disasters. We analyzed digital maps representing the indicators listed above using GIS. We also conducted a survey and face-to-face interviews to evaluate usability and sustainability of management which are not possible to understand through maps. As a result, we identified that suitability of public spaces and facilities in downtown villages is higher than clustered and individual villages. In particular, suitability of infrastructure facilities, social welfare facilities, and income generation facilities in downtown village are higher than those in clustered and individual villages. The suitability of tourism facilities is generally lower than other types of public facility across the three types of villages. Tourism facilities in clustered village have been identified especially unsuitable compared to other types of villages. We expect the outcome of the research is helpful to improve allocation of public spaces and facilities in rural villages.

Background: Safety data sheets (SDSs) are hazard communication materials that accompany chemicals/hazardous products in the workplace. Many SDSs contain dense, technical text, which places considerable comprehension demands on workers, especially those with lower literacy skills. The goal of this study was to assess SDSs for readability, comprehensibility, and suitability (i.e., fit to the target audience). Methods: The Suitability Assessment of Materials (SAM) tool assessed SDSs for suitability and readability. We then amended the SAM tool to further assess SDSs for comprehensibility factors. Both the original and amended SAM tool were used to score 45 randomly selected SDSs for content, literacy demand, graphics, and layout/typography. Results: SDSs performed poorly in terms of readability, suitability, and comprehensibility. The mean readability scores were Flesch-Kincaid Grade Level (9.6), Gunning Fog index (11.0), Coleman-Liau index (13.7), and Simple Measure of Gobbledygook index (10.7), all above the recommended reading level. The original SAM graded SDSs as "not suitable" for suitability and readability. When the amended SAM was used, the mean total SAM score increased, but the SDSs were still considered "not suitable" when adding comprehensibility considerations. The amended SAM tool better identified content-related issues specific to SDSs that make it difficult for a reader to understand the material. Conclusions: In terms of readability, comprehensibility, and suitability, SDSs perform poorly in their primary role as a hazard communication tool, therefore, putting workers at risk. The amended SAM tool could be used when writing SDSs to ensure that the information is more easily understandable for all audiences.

In this study, a method that can objectively and systematically design the layout of user interface components was developed. In order to explain its application method, the method was applied to the layout design of facsimile. In particular, in order to validate the suitability of the method, comparison tests were performed for the case of facsimile. Computer simulators for layout design were made using Micromedia Flash and comparison evaluation for an existing layout and a new layout was performed in three aspects. The first comparison method was to measure and compare its movement distance when carrying out a task in two layout models. The second one was to measure and compare users' performance. The last one was to measure and compare users' subjective satisfaction after using two models. As the result, new layout design was better than the existing design in all comparison tests. The movement distance of the new layout design model was shorter than the existing model. And, its performance including task completion time and error frequency was better and users' satisfaction was higher than the existing. In conclusion, the method that was developed in this study can be very effectively used in the layout design of user interface components.

토지적성평가는 토지가 가진 물리적 특성, 공간입지적 특성, 주변환경 특성들을 토대로 토지의 이용가능성과 보전 필요성에 따라 등급을 평가$\cdot$구분하는 것이다. 따라서 적성값의 산정과 등급 부여 기준 등의 평가방법이 얼마나 합리적인가에 따라서 평가결과의 신뢰성이 좌우된다고 볼 수 있다. 본 연구는 현행 토지적성평가의 평가방법을 비평적으로 검토하여 평가방법의 문제점을 도출하고, 보다 적정한 종합적성값 산정방법과 적성등급 부여방법에 대한 개선방안을 모색하는 데 목적을 두었다. 각 평가지표에 대한 임계치 설정과 가중치를 적용하는 대신에 선형변환법을 적용하여 지표들을 점수화하고, 모든 평가지표 점수를 합산하여 종합적성값을 산정한 후, 이를 서열화하여 면적비율을 기준으로 적성등급을 구분하는 방법을 대안으로 제시하였다. 사례지역을 대상으로 현행 지침에 따른 평가방법과 대안에 따른 평가방법 결과를 비교해 본 결과 대안에 따른 결과가 현행 지침에 의한 결과보다 평가지표 의 측정치 분포패턴을 보다 잘 반영해주는 점수로 변환하며, 종합적성값 산정 결과도 현실성을 더 잘 나타내는 것으로 검증되었다. 무엇보다도 위성영상을 통해 판독된 현지의 토지이용 현황을 참조해본 결과 대안적 평가방법에 따른 적성등급 부여가 칠씬 더 적정한 것으로 판정되었다. 뿐만 아니라 대안에 따른 적성등급 부여방식이 표준화지수로 변환시켜서 등급을 부여하는 현행 지침의 문제점을 개선해주고 보다 유연성을 부여해주는 합리적인 방법이라고 평가될 수 있다.

본 논문에서는 반응변수가 이진형인 분류모형에 대한 평가측도들의 특성을 파악하고 사용하기 적합한 평가측도인가를 살펴보았다. 고려한 측도는 정분류율, 민감도, 특이도, 정밀도, F-measure, HSS (Heidke's skill score)의 6개이다. 각 측도들은 이원분할표에서 x(실제로 1인 비율), y(1로 예측되는 비율), z(실제와 예측이 모두 1인 비율)을 사용하여 표현하였다. 본 연구는 평가측도가 사용하기 적합한 측도가 되기 위한 조건으로 두 가지를 제안하였다. 제1조건은 랜덤모형인 경우에 평가측도는 x와 y에 대해 상수이고, 제2조건은 평가측도의 식이 세 변수들(x, y, z) 모두로 이루어지고 z에 대해서 증가함수이고 x와 y에 대해서 감소함수이어야 한다는 것이다. HSS는 두 조건을 모두 만족하므로 이진형 반응변수의 분류모형에 대한 평가측도로 항상 사용이 적합하고, 다른 측도들은 제한된 범위 내에서만 사용하는 것이 좋다.

The purpose of this study is to investigate the sin satisfaction and fitness of Chinese women for Korean-made women's suits. The study methodology was questionnaire survey and the subjects were randomly chosen, 20 to 49-year-old female shoppers at department stores in Beijing, China. The data analyses were performed with SPSS 12.0 through descriptive analysis, t-test, and crosstab analysis. The findings were as follows. Chinese women assessed both the fit satisfaction and fit suitability levels of Korean-made women's suits available in China to be higher than that of Chinese-made women's suits. Paticularly, in the tan of slacks showing the lowest suitability level among Chinese-made women's wear, Korean-made women's suits in China had outstandingly high suitability level. In the case of jackets, however, the Korean-made women's suits went through more fixings, on average, than Chinese-made women's suits. In addition, more fixings were done for enlargement than for contraction, which necessitated the measure changes.

The conservation of stream habitats has been gaining more public attention and fish habitat suitability index (HSI) is an important measure for ecological stream habitat assessment. The fish habitat preference is affected not only by physical stream conditions but also by water quality of which HSI was not available due to the lack of field data. The purpose of this study is to estimate the HSI of Zacco platypus for water quality parameters of water temperature, dissolved oxygen (DO), and biochemical oxygen demand (BOD) using the water environment monitoring data provided by the Ministry of Environment (ME). Fish population data merged with water quality were constructed by spatio-temporal matching of nationwide water quality monitoring data with bio-monitoring data of the ME. Two types of the HSI were calculated by the Instream Flow and Aquatic Systems Group (IFASG) method and probability distribution (Weibull) fitting for the four major river basins. Both the HSIs by the IFASG and Weibull fitting appeared to represent the overall distribution and magnitude of fish population and this can be used in stream fish habitat evaluation considering water quality.

One of the most time consuming issues in a city development is the identification of suitable areas for urban infrastructures and proper land uses. Suitability analysis is the process and procedures to find the best available land in given area -that is, the ability of a system to select the needs of users in land use. This paper studied the usage of Geographic Information System technique and methods for the selection of the most appropriate sites for public park in the city of Gwangju. GIS was used as a standard technique to find the best available sites for development in urban areas. For this cause, digital elevation model and spatial data were used to produce different thematic layers by using software Idrisi. Criteria for finding the suitable site for park development were decided to evaluate the land and the followings 4 criteria were selected: on land with less than 3 degrees in slope, outside a 200m buffer around lakes, on land currently designated as forests, and 20ha or greater in size. To meet and measure each criterion, distance and context operators were applied to reclassify the importance of certain weight and Boolean images were generated to meet the criteria. These weights and maps has been combined using ArcGIS tools and the final map was prepared showing the most suitable sites. We may assist city planners and government officials in future development of public facilities including parks and related land use plans at urban level and act as to ensure proper land use planning and management of the urban areas.
