The multi-disciplinary research project Strengthening Local Authorities in Risk Management (SLARIM), initiated by ITC, includes three case study cities in Asia. An important question is: what are the essential data for risk management and how to access such data. The role of common sources (e.g. census data), data derived from remote sensing (high-resolution satellite imagery, aerial photos), and data from close sensing (field observation, including mobile GIS) to acquire essential risk management data will be discussed. Special attention is given to the question of the minimum area and to disaggregating population data. A few examples are given of Kathmandu / Lalitpur, Nepal.

선박운항시스템은 첨단화 되고 있으며, 선박충돌회피시스템에 관한 연구가 활발히 진행되고 있다. 그럼에도 선박 충돌사고 빈도수는 줄어들지 않는 설정이다. 시스템에 의한 충돌회피 조종에도 불구하고 근접거리로 충돌위험이 계속 존재한다면, 충돌위험 결정 및 판단기준에 있어서 단순히 TCPA, DCPA만의 입력변수 사용은 근접상황에서 충돌위험회피에 도움을 주지 못한다. 최근 5년간 국내 선박충돌사고 상대선 초인거리 조사에 의하면 약 $45\%$가 2마일 이하 근거리 초인하는 것으로 분석된다. 이런 요소는 선박조종성능 특성과 행위결정을 위한 시간적 특성의 영향을 많이 받는 근접조우를 유발한다. 따라서 근접상황에서 선박충돌회피동작 결정에 관한 연구는 안전항해의 필수적인 요소라고 할 수 있을 것이다. 본 논문에서는 선박조종성능 특성에 따른 선회조종과 선박의 거동을 분석하여 근접상황에서 신속하고 올바른 충돌회피 조선을 지원할 수 있는 선박충돌회피지원 모델을 제시한다.

The purpose of this study was to investigate the effect of ILIB(Intravenous Laser Irradiation of blood) on Meridian-Heart Circulation CMP and Hyperlipidemia. Circulatory symptom of 20 patients was treated with ILIB. After 10 times' treatment, changes of total cholesterol, HDL-cholesterol, triglyceride and Meridian-Heart Circulation CMP value were observed. The results were as follows : 1. In observation of Meridian-Heart Circulation CMP value, significant increase was observed in both pre-ID generation and post-ID generation. So, distinctive observation between pre-ID generation and post-ID generation became not relatively significant. 2. In observation of Meridian-Heart Circulation CMP value, significant increase was observed in both left and right. So, distinctive observation between left and right became not relatively significant. 3. In observation of Meridian-Heart CMP value, significant increase was not observed in control group, but significant increase close to normal value was observed in treatment group after treatment of Intravenous He-Ne Laser Irradiation. 4. In observation of Meridian-Circulation CMP value, significant increase was not observed in control group, but significant increase close to normal value was observed in treatment group after treatment of Intravenous He-Ne Laser Irradiation. 5. In concentration of plasma total cholesterol and plasma triglyceride, significant decrease was not observed in control group, but significant increase was observed in treatment group after treatment of Intravenous He-Ne laser Irradiation. 6. Significant concentration change of plasma HDL-cholesterol was not observed in both control group and treatment group. From above results, it was thought that Intravenous He-Ne Laser Irradiation was significant effect on heart circulatory system in human body.

Objective : Chronic subdural hematoma (cSDH) is common condition in neurosurgical field. It is difficult to select the treatment modality between the surgical method and the conservative method when patients have no or mild symptoms. The purpose of this study is to provide a suggestion that the patients could be cured with conservative treatment modality. Methods : We enrolled 16 patients who had received conservative treatment for cSDH without special medications which could affect hematoma resolution such as mannitol, steroids, tranexamic acid and angiotensin converting enzyme inhibitors. The patients were classified according to the Markwalder's Grading Scale. Results : Among these 16 patients, 13 (81.3%) patients showed spontaneously resolved cSDH and 3 (18.7%) patients received surgery due to symptom aggravation and growing hematoma. They were categorized into two groups based on whether they were cured with conservative treatment or not. The first group was the spontaneous resolution group. The second group was the progression-surgery group. The mean hematoma volume in the spontaneous resolution group was 43.1 mL. The mean degree of midline shift in the spontaneous resolution group was 5.3 mm. The mean hematoma volume in the progression-surgery group was 62.0 mL. The mean degree of midline shift in the second group was 6 mm. Conclusion : We suggest that the treatment modality should be determined according to the patient's symptoms and clinical condition and close observation could be performed in patients who do not have any symptoms or in patients who have mild to moderate headache without neurological deterioration.

Forest fire happens every year at Yeongdong, Gangwon-do, due to the strong local wind during the spring time and it causes a huge damage. This wind is named "Yangganjipung" or "Yanggangjipung" that blows along Yeongdong. However, the occurrence conditions of the wind have been still unclear. To identify the occurrence mechanism of local strong wind through three-dimensional observation data, Gangwon Regional Meteorological Administration performed Joint Gangwon-Yeongdong 3D Observation Project in 2020. The special observation was carried out for 6 times from March to April. The observation data was analyzed by focusing on the structure of synoptic pressure distribution and inversion layer. The result showed that the strength of wind is different depending on the latitude of low pressure, intensity of inversion layer, and changes on height in the south-high and north-low pressure distribution. As the interval of the upper and lower parts of the inversion layer was narrow, the strength of the wind became stronger, which is one of the observational characteristics of the springtime wind pattern at Yeongdong, Gangwon-do. In future, the clear mechanism of the local wind in the Yeongdong during the spring time is expected to be verified based on the accumulative observation data and close analysis.

On March 6 2021, Apophis made a close approach to the Earth with a minimum distance of 0.11 AU when the apparent magnitude reached up to V~16. This was the most favorable condition to observe this asteroid until its 2029 encounter. The observations during this apparition were extremely important to determine major physical properties, such as size, rotational state, 3D shape model, surface mineral properties. So, we organized the observation campaign during the 2021 apparition. The main goals of our campaign are to refine the spin state and 3D shape model and check the surface composition variations. The campaign involved dozens of countries and included ground-based photometry and spectroscopy, and spacecraft observations. Our timely observation campaign will provide essential data in planning the operation scenario for the space mission. In this presentation, we will report the preliminary result of the Apophis observation campaign during the 2021 apparition.

This research, which has been planned to appreciate the features of continuous observation of space, has applied the procedure of acquiring continuous visual information when the act of watching takes place along the time to analyze the space characteristics through the scenes and time so that the features of attention shown in the process of acquiring visual information at the time of observing continuous scenes might be estimated. For analysis of the features of continuous observation was set up the premise that the features of observation and perception vary depending on gender, when the women shops in department stores were selected as research objects. The observation features found at the time of continuous observation of selling spaces in department stores were focused on two analysis methods in order to compare the differences and characteristics of the two. The followings are the findings. First, the area with predominant observation was found to be 87.1% in both methods. It was found that the analysis of observation features by "Analysis I" was useful for inter-sectional comparison of continuous images. Second, in case of extracting predominant sections, the ceiling or the structures which are the backgrounds rarely attracted any eyes. Depending on analysis method, there was the gap of 14.3%~25.0% between observed sections. Third, in case that the hall is curved, the eyes were found to be expanded from side to side and up and down. The review of observation numbers of predominant sections makes it possible to decide whether it should be regarded as (1) unstability or (2) expanding search, and when the images are enlarged from distant view to close-range view, the weakening vanishing point results in the increase of expanded search of surroundings. Accordingly, it was found that the characteristics of images has effects on the observation features when any space was continuously observed. Furthermore, the difference of analysis methods also was found to be likely to cause big differences in the results of analyzing observation features.
