  • In this study, we analyzed typhoon affecting Korean Peninsula and runoff characteristic changes according to the typhoon based on Sumjin river dam, a representative multi-purpose dam. We quantified typhoon flow by applying the typhoon domain, and will provide base data for climate change adaptation and counterstrategy through correlation analysis of the change of typhoon statistical data and Indicators of Hydrologic Alterations (IHA). Korean Peninsula impact typhoon has a great effect on the scale of peak flow and the change of occurrence time. The occurrence frequency and duration of the peak flow were analyzed to be relatively unrelated to the typhoon affected by the Korean peninsula. These changes were also confirmed in the correlation analysis results. Correlation coefficient between the peak flow (0.41) and peak flow occurrence time (correlation coefficient = 0.83) was positively correlated with the Korean peninsula influenced typhoon.

  • Because most applications of vision-based object tracking demonstrate satisfactory operations only under very constrained environments that have simplifying assumptions or specific visual attributes, these approaches can't track target objects for the highly variable, unstructured, and dynamic environments like a traffic scene. An adaptive fusion framework is essential that takes advantage of the richness of visual information such as color, appearance shape and so on, especially at cluttered and dynamically changing scenes with partial occlusion[1]. This paper develops a particle filter based adaptive fusion framework and improves the robustness and adaptation of this framework by adding a new distinctive visual attribute, an image feature descriptor using SIFT (Scale Invariant Feature Transform)[2] and adding an automatic teaming scheme of the SIFT feature library according to viewpoint, illumination, and background change. The proposed algorithm is applied to track various traffic objects like vehicles, pedestrians, and bikes in a driver assistance system as an important component of the Intelligent Transportation System.

  • Objective : Doctors who treat women in childbed have to pay attention to postpartum blues and depression which women in childbed can suffer from, as well as recovery of physical function. Methods : Subjects were 107 females who admitted in Woosuk Hospital of Oriental Medicine from September, 2000 to October, 2001 and made out the question paper within 10 days after delivery. The paper included EPDS(Edinburgh Postnatal Depression Scale) and many items known to be the factors related to postpartum blues and depression. Results : The rate of postpartum depression assessed by EPDS was 16.8%. As the result of analysis, there were significant statistic corelations between each group assessed by EPDS and age parity relation with husband yes or no living with parents-in-law. But there were no significant corelations between each group assessed by EPDS and education religion yes or no occupation delivery method sex of infant marriage type yes or no rearing the infant. Conclusions : We recognized that insufficiency- of delivery experience and stress due to bad adaptation after delivery are possible to be risk factors of postpartum blues and depression. More research should be taken on the corelation between postpartum depression and yes or no living with parents-in-law, because this result is opposite to the trouble between mother-in-law and daughter-in-law. In addition, more research is needed on corelation between physical condition, oriental-diagnosis of women in childbed and postpartum depression.

  • Alberti's De re aedificatoria is the earliest case in the history of Italian Renaissance architectural treatises dealing with recovery of antiquity through textual and archaeological pursuits. The key source of the Renaissance theoreticians was Vitruvius' De architectura. However, Alberti was keenly aware of inaccuracy and Hellenization of Latinity in this classical text, and tried to compensate them in his own treatise. Furthermore he claimed a reformed discipline of the architects as well as the patrons, and prescribed how future buildings and cities should be built, based on the proper authority of ancient architecture in proper and intelligible Latin. Such an adaptation of classical usage in order to reestablish a modern norm preceded in his earlier work Momus, a satire on the contemporary Italian society of his own by following the model of Lucian. Alberti's suggestion of proper government in Momus's phrase was expanded in De re aedificatoria, for he consider the buildings are subject to the rules of morality and public interests. He proclaimed that the nature of beauty is the reasoned harmony of every part within a body, and architectural beauty also lies on the harmonized arrangement of all the elements within an individual building and of all individual buildings and facilities within a city. For the architects to execute this task, he formulated the concept of lineanenta, the form derived from the mind in order to prescribe the proper place, numbers, scale, and orders for whole building structure. It is the future oriented city-plans and building designs to serve the public interest and the good of all the individual citizens who make up the City-State that Alberti pursued in his treatise.

  • Studies on vulnerability of cultural heritage and adaptation strategy to worldwide climate change have been actively carried out in advanced countries since the late 20th century, and this established a valid research methodology and piled up climate and deterioration dataset in the field of climate change. Meanwhile, we still have tasks to acquire related scientific data despite referencing political researches in Korea. Applying Korean future climate to impact analysis, deterioration of Korean stone heritage is likely prospected to change into complexity in terms of physical, chemical and biological weathering that may bring impacts on conservation business and administrative field of cultural heritage. Further studies will ensure detailed implication of climate change impact on Korean stone heritage by means of down-scaling analysis of areas to local scale and dataset frequency to an hour. It is important to sort out capability and vulnerability of the stone heritage to future environment, and to make an adaption and prevention strategies.

  • The rapid increase in the number of climate disasters combined with the scale of change and the diversification of natural disasters require a radical solution. In particular, the urban space is more complex, therefore we need to establish measures for disaster response and how to react to damaged infrastructure based on the phenomenon of an increase in the urban population and the impermeable layer being extended. The social problems related to the economic burden of land purchase and the securing of a disaster prevention system can be solved simultaneously by introducing the park system for disaster reduction into the public land of the green space in the city. The local government has recently adapted diverse systems of disaster mitigation and carried out pioneer projects according to the guidelines for the construction of the urban park for disaster prevention published by the Ministry of Land, Infrastructure and Transport. The purpose of this study is to propose a composition model for neighborhood parks to prevent disaster through urban green spaces which has the functions of water management and biotope conservation. The result of this study will contribute to utilize the climate change adaptation model for living area neighborhood parks in the existing urban structure.

  • The purpose of this study was to validate abuse outcomes included Nursing Outcomes Classification(NOC) developed by Johnson and Maas at the University of Iowa. A sample of 71 nurse experts working in university affiliated hospitals participated in this study. They were asked to rate indicators that examplified the outcomes on a scale of 1 (indicator is not at all characteristic) to 5(indicator is very characteristic). A questionnaire with an adaptation of Fehring's methodology was used to establish the content validity of outcomes. The results were as follows: 1. All indicators were considered to be 'supporting' and no indicators were considered to be 'nonsupporting'. 2. 'Abuse Recovery : Emotional' attained an OCV score of 0.780 and was the highest OCV score among abuse outcomes. The highest indicator was 'demonstration of positive interpersonal relationship'. 3. 'Abuse cessation' attained an OCV score of 0.739 and was the lowest OCV score among abuse outcomes. The highest indicator was 'physical abuse has ceased'. 4. 'Abuse Protection' attained an OCV score of 0.743 and the highest indicator was 'plans for avoiding abuse'. 5. 'Abuse Recovery: Financial' attained an OCV score of 0.762 and the highest indicator was 'court-ordered benefits received'. 6. 'Abuse Recovery: Physical' attained an OCV score of 0.767 and the highest indicator was 'resolution of physical health problem'. 7. 'Abuse Recovery: Sexual' attained an OCV score of 0.768 and the highest indicator was 'expression of confidence with gender identity'. More outcomes need to be validated and outcomes sensitive to Korean culture need to be developed.

  • The purpose of this study was to identify the superior exercise on the reduction of low back pain, between the Mckenzie exercise and the williams exercise. 24 chronic low back pain patients were randomly divided into 3 groups (Mckenzie exercise group = 8, williams exercise group = 8, control group = 8). Each group examined using the Borg scale in a reduction of low back pain, the EMG amplitude in a stationary sit-up position and in a stationary 1000 back extension position. The Results are as follow. 1. After the training period, the Mckenzie exercise group and the williams exercise group revealed reduction of low back pain, but the control group does not revealed it. 2. After the training period, there were no significant differences on the reduction of low back pain between the Mckenzie exercise group and the williams exercise group. 3. After the training period, no groups decreased on the abdominal muscle EMG amplitude. 4. After the training period, all groups revealed no significant differences on the abdominal muscle EMG amplitude. 5. After the training period, all groups decreased on the low back muscle EMG amplitude. 6. After the training period, all groups revealed no significant differences on the low back muscle EMG amplitude. Overall, the study suggested that the Mckenzie exercise and the williams exercise achieve the same effect on the reduction of low back pain, and the fact seems to be influenced by other factors without muscular adaptation.

  • Loblolly pine (Pinus taeda L.) is widely distributed in the southern part of the United States and it has been used as a major economic species in the region due to its excellent growth and stem straightness. The tree also grows only in the southern part of Korea because it is susceptible to cold. Recently climate changes have had widespread impacts on forest trees. Thus, the use of good quality seeds is prerequisite for assessing assisted migration adaptation trial. In this study, we conducted to investigate its cone and seed characteristics of each family, which is expected to improve seeds productivity for planting valuable timber trees. A total of 14 families were selected from the experimental forest in Boseong, Jeonnam province in 1981. The seed production capacity was estimated to range from 87.2 to 129.4 among families and the average was 111.3. The number of aborted ovules was investigated in the range of 11.4 to 29.5 for the first test and 7.4 to 22.2 for the second test. The average number of empty and filled seeds was 1.4 and 79.2 per cone, respectively. Based on the results, we can conclude that there is a strong correlation between the number of fertile scale and the seed production ability.
