Objective: The Back Mapper is one type of Rasterstereography and it can be used in the clinic without radiation exposure. The purpose of our study was to prove the reliability and validity of the Back Mapper and to compare it with the Spinal Mouse, which is an assessment tool for spinal curvatures using a wheeled mouse, and the Cobb angle by X-ray. Design: Cross-sectional study. Methods: Twenty healthy adults participated in the test to investigate for the inter-rater reliability, intra-rater reliability, and concurrent validity. The tests were performed with assessment devices for scoliosis such as the Back Mapper, Spinal Mouse and Cobb's angle. Data was analyzed by an intraclass correlation coefficient (ICC) value and a standard error of measurement for reliability and correlation analysis for validity. Results: Intra-rater reliability of the Back Mapper was good (Cronbach's ${\alpha}$=0.821-0.984, ICC=0.696-0.969) except for assessing the lordotic angle. Inter-rater reliability was good (Cronbach's ${\alpha}$=0.870-0.958, ICC=0.770-0.919) in assessment for trunk imbalance, rotation of scapulae, thoracic angle, lumbar angle, and kyphotic angle. The kyphotic angle in the Spinal Mouse had a significant correlation icompared with the Back Mapper (r=0.510, p<0.05), and the Cobb's angle from an X-ray had a significant correlation with trunk inclination (r=0.532, p<0.05). Conclusions: These findings provide good intra-reliability of the Back Mapper in healthy subjects, but the Back Mapper requires more experienced practice to have good inter-reliability. Also, the variables of the Back Mapper does not seem as appropriate compared with the Cobb angle by X-ray.

Parts of damaged trees are being transplanted in accordance with the Environmental Impact Assessment Manual. Problems such as death or poor growth are constantly being addressed in the process of transplanting trees from the forest they originally inhabited to temporary and final transplant sites. The purpose of this study is to analyze the differences in soil properties in the surrounding forest, the temporary transplant site, and the construction site and to suggest methods for improving the soil to make it suitable for the growth of transplanted trees. For 10 development projects, 2 soil samples were sampled from the surrounding forest, temporary transplant site, and construction site. A total of 60 soil samples were analyzed for physical and chemical properties. Among the physical properties such as coefficient of permeability, available moisture, and hardness, and chemical properties such as acidity, organic matter content, total nitrogen, and available P showed significant differences among groups. The soil of the construction site is harder than the surrounding forest because of construction equipments, the coefficient of permeability is higherthan the surrounding forest because of high sand content, and the available moisture was low. It does not retain the moisture necessary for plants in the soil and drains immediately. It is necessary to implement tillage to improve the physical properties and structure of the soil. In addition, it is necessary to cover the surface with wood chips or fallen leaves after adding mature organic matter to improve the physical and chemical properties of the soil together.

To assess premenstrual changes in adolescents, a self rating retrospective premenstrual assessment from(PAF) and a prospective daily rating form(DRF) were administered to 230 high school students who reported premenstrual changes. The results were as follows 1) According to typological categories of retrospective premenstrual assessment form, the most commonly reported changes in mood and behavior were major depressive syndrome(40.0%), impulsive syndrome(20.9%). Especially among the subtype of depressive syndrome, hostility feature and withdrawal feature were most frequent. The most commonly reported changes in physical condition were general discomfort(73.5%), fatigue(33.9%). 50.9% of all subjects reported impaired social function. 2) 41.2% of the subjects who met the criteria for typological categories of retrospective premenstrual assessment form were confirmed by prospective daily rating form. 3) According to different criteria of percent change method of assessing symptom change, 38.7% of all subjects had at least one mild premenstrual change and 23.5% had at least one moderate premenstrual change. 4) Using prospective daily rating form, overall psychological changes were confirmed more frequently than physical changes. Of the mild premenstrual changes, 'low energy, tired & weak', 'less or impaired work' were most common changes. Of the moderate premenstrual changes, the most common change was 'low energy, tired & weak'. 5) As attitude toward menstruation, 44.9% of the subjects with confirmed premenstrual changes had more negative attitude(disgusted) toward menstruation. 6) The subjects with confirmed mild or moderate premenstrual changes had only dysphoric mood changes or both physical and dysphoric mood changes, but did not have only physical changes. These results suggest that retrospective reports of premenstrual changes were partially confirmed by daily prospective ratings. A substantial number of adolescents appeared to experience premenstrual changes, and the most common confimed premenstrual change of mild or moderate severity was 'low energy, tired and weak'.

Purpose: We defined osteoarthritis of the knee as knee pain and crepitus in over 40 years old. The usual clinical manifestation include pain, stiffness, crepitus and loss of function. Methods: We studied 40 cases of the degenerative arthritis of knee clinically. The body mass index(BMI, weight(kg)/height($m^2$) was used as a measure of obesity. Pain self assessment scale by Million Index in according to age, occupation, BMI. Results: Gender by pain self assessment scale was 6.5 in male and 6.6 in female(P<0.05). The prevalence rates obese was 40%. Occupation by pain self assessment scale was 7.0 in Sitting and 5.7 in Standing(P<0.05). Prevalence was increased with age by pain self assessment scale in aged 40-69 years. Conclusion: It has been known that the obesity is one of the predispsing factors of the primary degenerative arthritis of knee. A flexion weight bearing view of the knee obtained at $30^{\circ}$ to $40^{\circ}$ of the joint flexion may be more sensitive in assessing damages to hyaline cartilage because the knee flexion is an important component of the stance phase.

This study conducted a vulnerability assessment on Korea's physical infrastructure to provide base data for developing strategies to strengthen Korea's ability to adapt to climate change. The assessment was conducted by surveying professionals in the field of infrastructure and climate change science. A vulnerability assessment was carried out for seven climate change events: average temperature increases, sea level rise, typhoons and storm surges, floods and heavy rain, drought, severe cold, and heat waves. The survey asked respondents questions with respect to the consequences of each climate change event, the urgency of adaptation to climate change, and the scale of investment for adaptation to each climate change event. Thereafter, management priorities for infrastructure were devised and implications for policy development were suggested. The results showed that respondents expected the possibility of "typhoons and storm surges" and "floods and heavy rain" to be the most high. Respondents indicated that infrastructure related to water, transportation, and the built environment were more vulnerable to climate change. The most vulnerable facilities included river related facilities such as dams and riverbanks in the "water" category and seaports and roads in the "transport and communication" category. The results found were consistent with the history of natural disasters in Korea.

Purpose: This study analyzes the predictive power of upper extremity activity and the activities of daily living in patients with stroke using an easy-to-use evaluation tool. Methods: The Fugl-Meyer assessment (FMA) of the upper extremity and action research arm test (ARAT) are performed, and the Korean modified Barthel index (K-MBI) is measured. The predictive power of the upper extremity activity level and the daily activity level are analyzed using regression analysis. The statistical significance level is 0.05. Results: The coefficient of determination, R2, for predicting the ARAT using FMA was high at 0.88, but the regression equation for predicting the K-MBI using the FMA and ARAT did not show a statistically significant difference. Conclusion: The assessment of the upper extremity should be performed at the activity level, as well as the impairment level. The assessment for predicting the activities of daily living should be carried out for each level of the international classification of functioning (ICF), disability, and health, which can be linked to daily life, in addition to the assessment of the upper arm. Future research should conduct more diverse analyses using the ICF assessment tools at various levels.

The objective of this study is to suggest a planning direction for the management and conservation of a rural landscape. For suggesting the planning direction, this study was classified rural landscape resources based on spatial type to understand the assessment of rural landscape. This study examined literature reviews and site investigations for collecting the data on the resources of a rural landscape to maintain rurality. First above all, it was classified into physical and non-physical resources. Non-Physical resources include elements such as inhabitants' will, leaders' will and the software. It is also to reflect all these factors on the planning. Next, this study classified the resources of a landscape into artificial and natural resources and applied these resources to rural areas which were divided into five types: industry area, life area, natural landscape area, program area and human behavior area. The pictures obtained from this field survey were used for a questionnaire survey to understand the value of a rural landscape. The contents of questionnaire survey were divided into two parts: the presentation condition of a rural land-scape and assessment of a rural landscape. Especially, the value of a rural landscape was divided into the ecological value, socio-cultural value and holistic value.

Service life of water pipes buried in the underground is considerably affected from various factors such as environmental characteristics, pipe characteristics, operation and maintenance, etc. Therefore it is difficult to determine their service life as uniformly the same value assigned by related laws and ordinances. As a result, the service life should be determined by the technical judgement based on the assessment for the condition of water pipes. In this study, It was established that the methodology could predict present and future failure risk, and plan short and long-term strategies for replacement/rehabilitation through the assessment for the physical deterioration and economical values of buried water pipe. The methodology was applied for the verification and reliability to several sites selected in multi-regional transmission pipelines. The proposed method could helps to support reasonable and economical decision of rehabilitation/replacement in the present and future. To improve conventional assessment method of aged water pipes, affecting factors are simplified based on the statistical analysis results from the measured data in the field and the physical deterioration mechanism for better reliability. Also, the guide-line is developed to carry out the reasonal rehabilitation planning through water pipe condition assessment.
