This study suggests basic data on optimum thermal insulation for spring wear through an investigation of subjective thermal sensation, self-health image and actual wearing conditions. A survey of university students using a self-administered questionnaire was conducted to collect data on subjective thermal sensation, self-health image, wearing conditions, demographics and physical characteristics. The variable of wearing conditions was measured as the response to the clothing they were wearing. Garment items (26 types for males and 41 types for females) were suggested and the items worn by the students were converted into the thermal insulation values for clothing. The main results are as follows. As for the body type perception, males perceived themselves as not fat while females perceived themselves as not thin. As for the health perception, males perceived themselves healthier than females. As for the climate adaptability perception, females were more sensitive to cold than males. The average thermal insulation of clothing was 0.97clo (0.34-1.95clo) with higher insulation for males than females. Students were more sensitive to the cold when their BMI was lower, their body surface area per body weight was larger, and the more they perceived themselves as not healthy. There was a significant correlation between the self-health image of sensitiveness to cold and the thermal insulation of clothing. The results were synthetically discussed in terms of environmental physiology.

This research was thereby made to study and analysis ecological, landscape, and stability qualities of roadside cut Slopes in expressways and national highways that went through revegetation works. Also, evaluation items and framework for integrated assessment of plant structure and restored state for the maintenance were suggested. Following is the summary of the result. firstly, for stabilization of introduced native plant species on roadside cut slops, assessment on the post-project environmental management through long-term monitoring and maintenance works must be made. It signifies a form of authentic recovery and restoration by the native plants. second, current evaluation framework on the test beds is well managed with clear evaluation standards and table while its method of assessing the post management with only test bed results lacks conformity with this study site. Newly developed evaluation framework on the post construction sites is estimated to be used as assessment standards on any roadside construction sites. Third, after site investigation distinction was observed among different revegetating construction types in the long-term perspective. Due to the different duration time of vegetation state between seed-spray measures(degraded in time) and layer-spray measure(maintained), the use of coarse straw-mat mulching work or Coir net was suggested in long term maintenance of cut slopes. forth, segmentation of post environmental assessment is organized into three large categories of "ecological", "stabile", and "landscape" qualities regarding post restoration quality and stability of slope through native plants with which categories marks 50, 30, 20 points of rates. fifth, components of the post environmental assessment were segmented in twelve categories driving results from former experimental construction and newly focused items on site. In the future, it is possible to propose a customized assessment method considering the location and location of construction work if the research on the application of post-environment assessment methods for road construction surface recording is conducted systematically.

This study was conducted to investigate the eating habits and food preferences of elementary school children belong to multi-cultural families and ordinary families. The data were obtained by interview based on questionnaire from November to December in 2012. The subjects of multi-cultural families and ordinary families were 99 and 376 children, respectively. In comparison with eating habits, the ordinary children showed higher scoring in the items of eating proteins, green and yellow vegetables, and fruits or fruit juice than those of multi-cultural children. The ordinary children ate less midnight-meals than those of multi-cultural children (p<0.05). Furthermore, the ordinary children ate kimchi more frequently than the multi-cultural children. It was significantly different (p<0.05) on the items of 'eating-out types' dietary habits between two groups. Education of mothers correlated with the ordinary children's eating habits more than multi-cultural families. In the investigation of the food preference to Korean foods, 'beef and radish soup', 'pumpkin porridge', and 'wheat flakes noodles' were more preferred by children of ordinary families than by those of multi-cultural families (p<0.05). To conclude, nutritional education for their parents should be done and maintained to keep a right eating habit of children of multi-cultural families even at home.

The performance of projects has always been an area of interest in the construction industry. Roles of all construction supply chain partners are necessary; however the role of a contractor firm in the construction project is pivotal. So, this research intended to explore a Construction Firm's performance criteria which could measure the level of performance of that firm in an ongoing project. Data was collected from construction professionals working in three principal project participant organizations, namely Owner, Consultant and Contractor. A total of 113 nos. of performance measuring items were sorted from literature review and used to collect data. Statistical tools processed by SPSS program was employed to analyze the data. Out of total 113 items, only 65 nos. of variables were found to be acceptable to every population group of this study. Factor analysis revealed 12 key performance predicting factors (KPPF) with 53 predictive indicators. 12 KPPFS with index weight are: work progress and smoothening (9.3%), change order management and work accuracy (9.1%), business relationship building (8.1%), adequacy of construction work procedure (8.6%), quality performance (8.0%), health and site safety adequacy (8.8%), Innovative contractor (8.0%), adequacy of construction site information (6.8%), compliance with contract plan/specification requirements (8.9%), creditworthiness and financial capability (8.3%), intra-agency relationship and responsiveness (7.0%) and resource management (9.2%). These results could be useful to project management body to evaluate performance of its contractor firm on site as well as the contractor itself to assess own performance and its subcontractors on-site.

The investigation of the surface areas, volumes and sizes (circumference, length, breadth) changes has been performed on women during menstruation, non-menstruation, pregnancy and post-pregnancy periods. (1) During menstruation and non-menstruation periods: The subjects were 30 healthy women from 19 to 24 years of age. The changes of lower leg areas were measured using the paper replacement method, showing an increase of 0.71% in surface during the menstruation period. The changes of lower 1g volumes were measured by the water replacement method, showing an increase of 1,74% in volume during the menstruation period. The correlation between the surface area changes and the volume changes was of r=0.45. The greatest change among the four parts of the leg was found at the ankle in both experiments. We measured also the foot length(1), the ball of foot girth(2), the foot breadth(3), the instep height (4), the instep girth(5), the ankle girth(6), the calf circumference(7) and we found the greatest changes in(4)=3,92% in(5)=0.79% and in (7) =0.84%. (2) During pregnancy and post-pregnancy periods: The subjects were 3 women, two pregnants(both from the 24th to the 36th week of pregnancy during the experiment) and one post-pregnant(from the second week to the eighth week during the expriment). For the first two subjects, we measured only the last 6 items of the preceding experiments(foot length(1),ball of foot girth(2), (3), (5), (6), (7)), Showing the greatest changes in the instep girth(5) and the calf circumference(7). In the case of the post-pregnant subject, these two items (5) and(7) decreased sharply during the second, third and fourth week and remain approximately the same afterwards.

This research intended to estimate the damage information from torrential rainfalls using airphotos and spatial data which have been rapidly increasing their applicability recently. The study area was Bonghwagun of Gyungsangbukdo where the large amount of damages were occurred from torrential rainfall in July, 2008. For this study, the database was constructed for the study area by collecting usable data. The interpretable items from the airphotos of 40cm spatial resolution were selected. Also, the useful GIS layers such as road were selected in the digital map to extract the damage information more accurately and rapidly. The damaged area was easily identified through the comparison of pre- and post-disaster airphotos. The recovery cost was estimated by applying unit cost to the damaged area. GIS's overlay function was used to extract the damage information of for individual items damaged. The method for extracting damages information using GIS and airphotos could be more efficient and cost effective in case of relatively wide and unapproachable damaged areas. It is also expected that the method using high resolution imagery would lead to minimize the secondary damages as well since it can facilitate the damage estimation within short period of time thereby supporting early securing budget for recovery.

TThis study was undertaken to make trial costumes of ball jointed dolls for promoting the beauty of Korean cultural product with historical research of upper class ladie's costume from late Goryeo to early Joseon, the very unknown period in the Korean costume history. The ladies' costume from late Goryeo to early Joseon are characterized by their full silhouette, fusion with clothings of Yuan and Ming, revival of early Goryeo styles, well-developed weaving skill of ramie, a showy costume from Buddhist civilization. After investigation of researcher with literature, painting, and relics in 13-14C, 8 clothing items were outsourced totally. Items were formed as a set concept, but consumer can choose each costume as an single item and can make varied mix also. Dart, small ties, and thick fabrics were used in doll costumes partly because ball jointed doll's body has different characteristics from that of human beings. Developing research of manufacturing company's system for ready-made product remains to be considered in the future.
