  • Trail is a main infrastructure for various forest recreational activities. In this study, the recreational supply (trail) and demand (trail program according to visitor characteristics, preferred forest activities) were studied. Through the application of a multiple correspondence analysis and cross tabulation analysis, 3 trails (Bukhansan trail, Uljin trail, Jirisan trail) were identified. On this study, visitor demands for trail program participation, preferred forest recreational activities, program contents and program operations. Visitors expressed positive attitude toward trail program participating and showed characteristics with the differences. Young visitors preferred active experience program and middle aged visitors more liked health program such as forest therapy. On site program and self guided interpretation were preferred for program operation. In Bukhansan trail, continuous health program (1~2 hours) would be proper and it needs to adapt various nature activities in the Uljin trail. For the Jirisan trail, self guided program would be developed in many ways.

  • The design of children's hospitals is highly dependent on color schemes. As a space shared together by both adults and children, the design of children's hospitals require color coordination that takes account of the users' characteristics. However, because the majority of prior research on color perception has focused overly on the emotional aspects, there is a necessity for more rational and scientific analyses to identify the characteristics of the visual perception of colors. Adopting this perspective in analyzing the characteristics of the visual perception of colors, this study aims to move beyond the abstract to focus on more objective methods, such as eye-tracking experiments, to examine the characteristics of hospital visitors' visual attention with respect to colors. Visual perception tracking experiment was conducted on the 2 chosen experimental images with a target group made up of adults and children, the following results were found. Firstly, spaces created with the preference colors of the different groups were found to develop a characteristic of developing higher attention. Secondly, observing the common tendencies for attention for adults and children, the highest region for visual concentration was formed towards the middle, as attention progresses to lower stages visually focused area changes in the order of upper-middle, left and right, and lower regions and edge regions show characteristics of not triggering attention Thirdly, it is understood that children's level of attention drops a lot faster than adults when identifying space therefore it is suspected that children need more elaborate color coordination than adults.

  • In complex buildings, Way-finding is the most important factor for safe evacuation. Recently, evacuation guidance systems using smartphones have been developed. However, smartphone evacuation guidance maps used in these studies appear different from those used in previous studies due to the lack of established standards. Therefore, in this study, we conducted a preference survey of evacuation guidance maps as a basic research for establishing evacuation guidance maps using smartphones. The components of smartphone evacuation guidance maps were selected using regulations and analyses conducted in previous studies, and preference surveys were conducted using the size of each component. Through this research, we suggested a method to create a high preference for each component of an evacuation guidance map.

  • The purpose of this study is to investigate the effects of task-oriented activities on hand functions in patients with hand injuries. From December 2011 to October 2012, sixteen patients with hand injuries at C Hospital in Changwon, Gyeongsangnam-do, Korea were randomly divided into two groups. One group was subjected to task-oriented activity and the other to general exercise. Two groups performed each activity once a day, three times a week, for four weeks. The group with the task-oriented activities was provided with the tasks according to subject-preference based on the result of Canadian Occupational Performance Measure (COPM). To verify the effect of intervention, the following hand function measures were used: grip strength, pinch strength, and the range of opposition and abduction, Purdue pegboard test and Disabilities of the Arm, Shoulder and Hand (DASH). Both groups showed significant increase in all of the hand function measures after 4-week activities(p<.05). The task-oriented activity group was significantly different from the control group in powers for tip pinch, lateral pinch and three-jaw chuck pinch, Purdue pegboard test and DASH(p<.05) except in grip strength and the range of opposition and abduction suggesting better improvement in hand functions. This study shows that task-oriented activities improve the hand functions more effectively in patients with hand injuries.

  • Purpose: The aim of the present study was to investigate toilet terms and pictograms recognized by elders living in Seoul and Incheon. Method: Data were collected from 308 elders by individual interviews using questionnaires. Result: As for the name of places for elimination, those elders responded Hwajangsil 88.3%, followed by Byeonso 49.3% and Dwitgan 44.4%. Most elders preferred Hwajangsil as the term indicating the place for elimination. The mean age of the group preferred Bunso was significantly higher than that of the group preferred Hwajangsil, whereas educational level was higher in the latter group. Of the 256 respondents, 55% preferred the pictogram of international toilet sign, while 34.8% preferred the pictogram of toilet stool. Those with no formal education tended to prefer the pictogram of toilet stool. Conclusion: The term Hwajangsil is suggested for indicating toilet for elders in general. Other terms familiar with residents need to be investigated in the facilities for elders and those terms should be used in combination with Hwajangsil. English toilet signs alone are not recommended for elders. Simple pictograms of toilet stool is suggested for elders with low educational level. Toilet signs for elders need to include both terms and pictograms.

  • 쌀은 전 세계에서 매년 약 4억 톤이 생산되어 세계인구의 약 45%에게 주식으로 제공되고 있다. 우리나라에서는 쌀 농사가 농업소득의 약 44%를 차지하는 농가의 주 소득원으로 경제적 비중이 크다. 또한 WTO 개방경제 체제에서는 쌀 생산농가가 생존하기 위해서는 생산비 절감을 통한 가격경쟁력 제고와 품질향상을 통한 소비자 선호도 확보가 가장 중요한 과제이다. 지금까지 우리나라의 벼농사는 생산비 절감이나 품질향상보다는 수량증대에 치중하여 쌀 산업의 국제경쟁력은 매우 취약한 실정이다. 손 모내기에서 중묘 기계이앙 기계기술이 확립되어 확대보급 되었고 이보다 육묘비용 및 노력을 절감할 수 있는 어린 모 재배 기술이 보급되기 시작하였으나, 미국 등 선진국의 벼농사 노동 투하시간 3.5시간/㏊에 비하여 우리나라는 328시간/㏊ 쌀 생산비는 미국의 2,018천원/㏊에 비하여 우리나라는 5,105/천원㏊로 월등히 높아 노동 투하시간을 획기적으로 줄일 수 있는 기계기술 개발이 요구되고 있다.
