  • Information Technology (IT) makes a great contribution towards improvement of productivity in construction industry. Because most of researches of construction industry's IT are focused on the whole field of the industry or development of information system, however, these have no regard for conditions in fields. Thus, this study proposes the requirements in order to improve the productivity and efficiency of field execution of construction industry. To achieve this aim, the surveys are conducted of the problems and conditions of IT application on site workers and managers. As a result, the followings are suggested: (1) user training should be exercised continuously, (2) infrastructure of IT constructed, (3) total management system of field execution developed, and (4) the development of IT system focused on fields. Therefore, this study provides meaningful proposal that can be set up basic direction toward IT investment and IT system development.

  • This study is to develop cultural products based on 'Jeju Choga', which means the traditional houses in Jeju. For the product development, old literature review, field surveys, and consumer surveys were employed. Through old literatures and field surveys, the unique and visual characteristics of Jeju Choga were confirmed: A thatched roof with lattice pattern, a side wall and fences with porous stones, a 'Jungnang' serving as a gate, and a 'Pungchai' preventing strong sola radiation and 'Ollai' meaning a narrow street in front of the Choga. As a results of consumer survey conducted before the development of products, consumers highly recognized and associated Jeju Choga as Jeju representative image. The six basic patterns of Jeju Choga were drawn and eight textile designs were created through the repeated arrangements of the basic patterns. Using the created textile designs and digital printing method, the eleven new fabrics with the patterns of Jeju Choga were developed. The various kinds of ten bags and tow wallets made with the new fabrics. As a result of consumer evaluation for the twelve products made in this study, the scores of preference and purchase intention were above the average work for the most products of them. In particular, the preference and purchase intention of the square shoulder bag, the big-size shopper bag, and the small-size cross bag were very positively evaluated. Therefore, it is confirmed that Jeju Choga could be very useful as a motif for the development of cultural products focusing on Jeju tourism souvenir market.

  • As Gangwon-do Province needs an environmental-friendly alternative tourism according to low carbon green growth, this study analyzes specialized fields in green health industry, selects seven specialized fields in green health industry that is fit to Gangwon-do Province, and suggests a development strategy by conducting recognition surveys on preference and impotence of the specialized fields. Surveys and interviews are conducted of 106 students at Green Health Industry Education Center which is operating by Kwandong University and 84 persons who work at medical institutions and tourism related companies in Ganwondo. The surveys and interviews were completed from November 5 to November 19 in 2010, determined factors through a factor analysis when they have many questions, and analyzed by using SPSS 14.0. Out of the seven specialized fields, rest & recuperation field is highly recognized. In order to have competitive edge compared to other self-governing provinces, Ganwon-do Province should prioritize rest and recuperation field. A healthcare program in the green health industry specific to Ganwon-do Province includes hot springs and spa programs as a priority. Gangwon-do's hot springs are deemed to be competitive resources as global medical tourists prefer spa and sauna healthcare programs, while the province promotes its spring resources and builds medical tourism infrastructures. Gangwon-do Province can promote a medical tourism industry that is well suitable for the strength and characteristics of the province. It might pursue oriental medicine therapy tourism, which is related to a recuperating medical service that uses both oriental and western medicine. It can also run such programs as forest bathing (oxygen road), spring and spa, and sea water treatment, which are the specialized fields in green health industry with respect to recreation and healthcare.

  • The purposes of this study were to determine the actual state of the indoor thermal environment in apartment units and to analyze the relationship between the living factors and indoor thermal elements. The field surveys consisted of measurements of physical elements and observations of living factors. In addition, the residents of 20 apartment units were interviewed to survey their subjective response. Field surveys were carried out from January to March 2007. Measuring elements were air temperature, globe temperature, and relative humidity. The results showed that the average of indoor temperature for the houses was $21.2{\sim}27.2^{\circ}C$, while 4 houses exceeded the comfort zone. The average of globe temperature for the houses was $21.3{\sim}27.5^{\circ}C$, while 6 houses exceeded the comfort zone. The mean relative humidity was $19.5{\sim}58.8%$, which is a relatively dry condition. The residents' average clothing value was $0.39{\sim}0.89$ clo(average 0.68 clo). The average thermal sensation vote on each room was $4.2{\sim}4.8$, which is 'neutral' to 'slightly warm'. Living factors had significant effect on indoor temperature in regression analysis were ventilation time(outdoor air exchange), opening time of door through balcony, and gas cooker use time.

  • This study was carried out to investigate the causes of fish kills in the Yudeung Stream in Daejeon, Korea using literature reviews, governmental and our water quality monitoring data of the study site, rainfall data, intensive water quality monitoring during rainfall events, sediment pollutant contents and laboratory bioassay tests. Fish kill in urban streams can be caused by combined effect of reduction in dissolved oxygen concentration, increase in toxic material or increase in turbidity in waterbody due to introduction of surface runoff or effluent of combined sewer overflows after rainfall from the watershed areas. Despite of extensive and intensive field surveys and laboratory tests, it was found that those conventional methods have limitations to identify causes of fish kills in urban streams. It would be necessary to use dynamic water quality modeling to predetermine the range and level of water pollution in the stream and automatic water quality monitoring system that can collect water samples and detect water quality continuously.
