Malfunction of gutter systems in the slope area accelerate to percolate surface flow into underground and to cause the decrease of soil strength, Overflowing from gutter causes soil erosion from slope surface, secondary it is one of the main reasons to cause disaster in the hillside area. Much researches were reported and are undergoing about flood disaster in the down stream area, but rare in the upper reach(hillside). It is considered that improving function of gutter in the hillside is very important to prevent the disaster caused by rainfall. In this paper, After analyzing relationship between rainfall and disaster on the hillside in Busan, researches about having surface flow run into gutter effectively and preventing from overflowing outside of gutter on the hillside in Busan were carried out. Improved design methods of gutter are suggested to mitigate disaster in the sloping area by analysis of collected data and hydraulic model test.

To find out influence of water fluoridation program on the economic benefit effect, this study analyzed comparatively dental treatment indicators obtained from dental clinics at Sangdang-gu in Chenongju City, fluoridated community and Manan-gu in Anyang City, non-fluoridated community, from January 1, 2003 to the end of June, and the results are as follows: 1. If water fluoridation program is carried out in Anyang, non-fluoridated community, the number of treatment from caries and disease of tissues around dental pulp and root apex from age 6 to 18 for the first half of year 2003 is expected to decrease by 1,272, 636 for low estimation, and 1,908 for high estimation. And the treatment cost is expected to decrease by 40,888,000 Wons, 20,444,000 Wons for low estimation, and 61,333,000 Wons for high estimation. 2. Assuming that water fluoridation program is spread to all over the country, the number of treatment per year is expected to decrease by 2,492,018, 1,246,009 for low estimation, and 3,738,027 for high estimation. And the treatment cost is expected to decrease by 80,105,075,000 Wons, 40,052,537,000 Wons for low estimation and 120, 157,612,000 Wons for high estimation respectively. 3. For Yeong-un water supply management office which has 48,925 water supply personnel, the benefit/cost rate was 2.9 times, and for Jibuk water supply management office which has 239,751 water supply personnel, the benefit/cost rate was 9.0 times. As the water supply personnel increased, the cost increase of water fluoridation program was little and as the scale got large, the economic effect was very large. Improving national oral health is thought to be associated with expense retrenchment of oral health insurance financial. So it may need to extend using tap water to all the area of the country and additionally establish confidence through an active public relations and education of water fluoridation program.

Background: The leg length discrepancy (LLD) have been implicated with degenerative diseases since the early 1970s, which also causes musculoskeletal asymmetry problems. The LLD appears due to factors such as balance ability, response time, and muscle strength between the shorter and longer leg. In this study, the effect of manual therapy to LLD has been studied. Methods: Manual therapy has been applied on shorter leg of 30 patients with LLD. The manual therapy was conducted for 2~3 minutes 3 times a week for 4 weeks. Results: The leg length of shorter leg were measured at initial baseline and after 4 weeks. the average leg length of shorter leg increased from 94.10 cm to 94.33 cm. Conclusion: This paper reports that the manual therapy has positive effects on LLD. It was studied by conducting manual therapy on muscles and joints related to shorter leg. In the future, the muscles and joints of the longer leg should be considered and various age group should be studied to develop the understanding of the effect of manual therapy on LLD.

Purpose : Neck pain is commonly experienced by both adolescents and adults. The purpose of this study was to measure neck disability index(NDI) and the cervical range of motion(CROM) following spinal manipulation and mobilization techniques. Methods : Thirty participants(manipulation=15, mobilization=15) with mild neck disability volunteered for this study. It was used to measure NDI with NDI questionnaire and six motions(neck flexion and extension, left and right lateral flexion, left and right rotation) with the CROM instrument. Independent t-test and paired t-test were used to estimate NDI and CROM, and compared left with right motions. Results : A significant decrease in NDI were found after spinal manipulation and mobilization treatment(p<.05). A trend toward increase in all cervical motions(flexion, extension, left and right lateral flexion, left and right rotation), after interventions, were revealed(p<.05). The significant differences were not found on NDI and CROM between the group(p<.05). It was presented asymmetric motions in cervical lateral flexion(p<.05) before and after treatment. Conclusions : Our results suggest that manipulation and mobilization probably provide at least short-term benefits for patients with mild neck pain. It is needed to be studied the factors and preventive methods influencing the asymmetric cervical motion.

Background: In the present study, we examined gender roles, job satisfaction, and the relationship between the two among orthopedic manual physical therapists (OMT). Methods: The subject of this study was 208 physical therapists working in the general hospital and rehabilitation in Daejeon. In order to examine the nature of the subject, we calculated the ratio of second finger length for fourth finger of predominant hand and completed the questionnaire to determine the general characteristics and job satisfaction. Results: The OMT and NOMT (non OMT) digit ratio results were not significantly different (p>.05). Digit ratio based on gender was also not significantly different between groups (p>.05). Among the job satisfaction survey items, OMT was significantly higher than NOMT in terms of Pride, Reflection of opinions, aptitude match, and field satisfaction (p<.05); however, there were no significant differences between groups for the remaining items. Digit ratio was not significantly related to any of the job satisfaction items (p>.05). Conclusions: We determined that gender roles had a limited influence on selecting and continuing with orthopedic physical therapy.
