Purpose: The purpose of study was to identify problems in disaster recovery resource management and operation through on-site investigation and utilize them as improvement proposal for disaster recovery resources management by local governments. Method: Areas with high natural and social disasters recorded in historical and yearly records of natural and social disasters, related books, and annual reports for 20 years were selected. The DRSS data of the selected local governments were analyzed and the reserve warehouse were selected for field survey. Result: It is analyzed that the current situation in the city hall and district offices is somewhat insufficient due to heavy work by the working-level officials of local governments on the storage of disaster recovery resources. The actual amount of stockpiles and DRSS data are somewhat different or missing because the input method and criteria are not clear at present when inputting the current data. Conclusion: To improve the management of the disaster recovery resource reserve, it is deemed that education of DRSS and training of best practices for the operation of disaster management resources are urgently needed, and that a systematic management of stockpiles using disaster prevention experts will be required.

Construction Research and Development (R & D) projects have been begun with the investment of 1.2 billions in 1994 and have been reached to 30 billions in 2004. During this ten-year period, a total of investment for construction R&D amounts to 125.7 billions (Total 418 construction R&D projects). However, the results of each R&D project could not apply to real construction site because each project has been performed by a small size (0.5 billions). In addition to those, the social interest on the construction R&D projects has not been received and those importance has not been recognized. Especially, there aren't still standardized methodologies or weighted measurement data for evaluating research performance of the construction R&D projects up to now. The construction R&D projects has been Invested on the basis of an annual technology demand survey rather than the research performance outcome. Therefore, it is important to establish a qualitative performance measurement model for evaluating construction R&D projects. This paper proposes a new research methodology for analyzing the performance measurement of the construction R&D projects. First of all, the Balanced Score Card (BSC) is used to evaluate the construction STAR technologies selected in this research. The performance items of BSC has been modified as four criteria such as "productivity, "knowledge accumulation," "training of students," and "welfare." The new research methodology developed in this paper is expected to use in establishing resonable construction R&D budget in the future.

The main purpose of this study was to find out the actual status of safety and heal th education activities in the manufacturing industries through survey of 136 plants in Seoul City and Gyunggi- Province Area which employ nurses being charged in the safety and health care services to the employees. A questionaire was mailed to the employees on the Mar. 2, 1987. Total 634 responds from 87 industries were collected by Apr. 20, 1987. Among the total, 618 responds from 80 industries were included in the analysis. The major findings obtainded from this study are summarized as follows; 1. Safety and health education activities in each industry: 1) The $67.6\%$ of safety directors surveyed were performing the education to the employees. And in case of medical directors, it was $18.8\%$ of them. 2) Periodically, annual safety' and health education programs were being drawn up in the $65.0\%$ of the industries (52 companies). And the $60.6\%$ of the planners were safety directors of safety staffs in charge. 3) It was only $27.5\%$ of the companies surveyed in which the safety and health education were performed more than an hour every month. In the $22.5\%$ of the companies, neither safety programs nor health education activities were performed. 4) In the $47.5\%$ of them, safety and health educations were performed in cooperation with related agencies such as health center. 2. The rate of employees participated in safety and health educations; 1) The received rates by subjects of the educations when labors were newly employed to their companies were as follows; education regarding danger and profer handling method of machinery and appliances: $64.2\%$, education regarding noxiousness and handling method of raw materials: $42.2\%$, etc. 2) The $63.6\%$ of the labors received educations on safety and health when they changed their work places. 3) The $74.8\%$ of the labors received specific safety and health educations. 4) The general safety and health educations were received by the $47.2\%$ of management and clerical personnel and $50.0\%$ of labors pre and post physical examination. 3. The main reasons of inactive performance of the educations were as follows; lack of knowledge and inexperience of the occupational safety and health staffs, lack of cooperations between themselves and low need of workers for safety and health education, etc. 4. The preferable subjects of educations for workers; (1) pre and post education of physical examination, (2) education regarding the prevention of accidents. (3) general health care, sex education and family planning, etc. As a result of this study, we can conclude that the safety and health education work in industries as the subject of this study is on the incipient stage. Appropriate measures are to be taken for the activation of safety and health education work such as; continuous public relations, financial and technical supports of the government, training of professional/occupational safety and health staffs, efforts of workers to receive the education and collaborations of the employers.

The issue presented in this paper are as follows: 1. Legislative actions of welfare-related law for the exceptional children. The legislative base for the evolution has been yet weak and ambigous at best for a formalization of what should be considered accepted practice and effective action in providing handicapped child and their parents educational rights and equal protection of the law. And they are under remote control of partial factor subject to social welfare law for children, and public law for education, promotion law for the exceptional child education, protection law for public aids. 2. Organization of government for the welfare services for the exceptional children. There is no sing of a push toward consolidation of effort for the welfare service of the exceptional children in this country that seeks to recapture a sense of unity, of coherence, of completeness from a reality made up of discontinuous fragments of humanitarian effora This presently that. as for the education of the exceptional child, by the section of the exceptional education in MOE (Ministry of Education), and/or as for welfare services and promotion actions, by the section of child welfare in MHSA (Ministry of Health and Social Affairs). One door type operation rooted in the specialization, and limited resources to evolve multi-purpose agencies that undertake to provide a broad range of tangible and concrete services, as well as supportive counselling and assessment, under a single management which plans and directs the allocations of resources, should be followed. 3. Facilities and recruitment of teachers for the exceptional children. In this country there are 54 facilities for special services, 56 schools for the exceptional education, and 3 colleges and equavalents that provide teacher training services leading to certification with IIO annual graduates. However, curriculum for exceptional children should be rearranged and reconstructed. Conclusion; Only as for social welfare institutions in community, this country produced a succession of specific purpose activities, over period of time, that accumulated to form the present network of hundreds of social welfare organizations and facilities Periodically major efforts were launched to revitalize or to improve the help-giving system. But they lack specialization to be effective, and the nature of multi-purpose center tends to be vague for the classified handicapped. Therefore, there, should be linkage between policy maker and community services to maintain some coherenty in preventive care, treatment, and after cares. At last, the effects of the current concept "the exceptional child" involved with their families, and their neighborhood should be considered in view of the people who consist about 25% of the total population.

This study evaluated the composition and distribution of marine litters on the sea-bed of the East China Sea. Surveys have been conducted by a benthic trawlnet of Dong-baek training ship of Yosu national university during the cruise of 2002-2004. Distribution density showed high value in C5 (north-western area of Jeju Island) with $110.3kg/km^2$ and those of annual mean were about $31-43kg/km^2$. Fishing gears such as nets, pots, octopus jars and etc. were about 42-72% of debris collected in the East China Sea. Composition ratio of rubber, vinyl. metal, plastic, glass, wood, cloth and etc. were within 25% except C5. Rope and drum showed strong fluctuations with 0-30% according to the trawling sites. Some vinyls and nets made in Korea, China and Japan were much collected. It is estimated that fishing gears were discarded to the sea by fishing operation, deliberately or not. An comprehensive program including continuous research, monitoring for marine litters in the Korean sea were necessary.

In this study, the artificial neural network model is applied for real-time dam inflow prediction and then evaluated for the prediction lead times (1, 3, 6 hr) in dam basins in Korea. For the training and testing the model, hourly precipitation and inflow are used as input data according to average annual inflow. The results show that the model performance for up to 6 hour is acceptable because the NSE is 0.57 to 0.79 or higher. Totally, the predictive performance of the model in dry seasons is weaker than the performance in wet seasons, and this difference in performance increases in the larger basin. For the 6 hour prediction lead time, the model performance changes as the sequence length increases. These changes are significant for the dry season with increasing sequence length compared to the wet season. Also, with increasing the sequence length, the prediction performance of the model improved during the dry season. Comparison of observed and predicted hydrographs for flood events showed that although the shape of the prediction hydrograph is similar to the observed hydrograph, the peak flow tends to be underestimated and the peak time is delayed depending on the prediction lead time.

Objective : Since less invasive endovascular treatment was introduced to South Korea in 1994, a considerable proportion of endovascular treatments have been performed by neuroradiology doctors, and endovascular treatments by vascular neurosurgeons have recently increased. However, few specific statistics are known regarding how many endovascular treatments are performed by neurosurgeons. Thus, authors compared endovascular treatments collaboratively performed by vascular neurosurgeons with all cases throughout South Korea from 2013 to 2017 to elucidate the role of neurosurgeons in the field of endovascular treatment in South Korea. Methods : The Society of Korean Endovascular Neurosurgeons (SKEN) has issued annual reports every year since 2014. These reports cover statistics on endovascular treatments collaboratively or individually performed by SKEN members from 2013 to 2017. The data was requested and collected from vascular neurosurgeons in various hospitals. The study involved 77 hospitals in its first year, and 100 in its last. National statistics on endovascular treatment from all over South Korea were obtained from the Healthcare Bigdata Hub website of the Health Insurance Review & Assessment Service based on the Electronic Data Interchange (EDI) codes (in the case of intra-arterial (IA) thrombolysis, however, statistics were based on a combination of the EDI and I63 codes, a cerebral infarction disease code) from 2013 to 2017. These two data sets were directly compared and the ratios were obtained. Results : Regionally, during the entire study period, endovascular treatments by SKEN members were most common in Gyeonggido, followed by Seoul and Busan. Among the endovascular treatments, conventional cerebral angiography was the most common, followed by cerebral aneurysmal coiling, endovascular treatments for ischemic stroke, and finally endovascular treatments for vascular malformation and tumor embolization. The number of endovascular treatments performed by SKEN members increased every year. Conclusion : The SKEN members have been responsible for the major role of endovascular treatments in South Korea for the recent 5 years. This was achieved through the perseverance of senior members who started out in the midst of hardship, the establishment of standards for the training/certification of endovascular neurosurgery, and the enthusiasm of current SKEN members who followed. To provide better treatment to patients, we will have to make further progress in SKEN.

The unsupervised domain adaptation can solve the impractical issue of repeatedly collecting high-quality training data every year for annual crop classification. This study evaluates the applicability of deep learning-based unsupervised domain adaptation models for crop classification. Three unsupervised domain adaptation models including a deep adaptation network (DAN), a deep reconstruction-classification network, and a domain adversarial neural network (DANN) are quantitatively compared via a crop classification experiment using unmanned aerial vehicle images in Hapcheon-gun and Changnyeong-gun, the major garlic and onion cultivation areas in Korea. As source baseline and target baseline models, convolutional neural networks (CNNs) are additionally applied to evaluate the classification performance of the unsupervised domain adaptation models. The three unsupervised domain adaptation models outperformed the source baseline CNN, but the different classification performances were observed depending on the degree of inconsistency between data distributions in source and target images. The classification accuracy of DAN was higher than that of the other two models when the inconsistency between source and target images was low, whereas DANN has the best classification performance when the inconsistency between source and target images was high. Therefore, the extent to which data distributions of the source and target images match should be considered to select the best unsupervised domain adaptation model to generate reliable classification results.

In this study, the purpose of this study was to conduct a basic study on the effectiveness and feasibility of the regulation of the Nuclear Safety Act for the department of radiology by examining the questionnaire on the satisfaction of on-campus practice while attending the department of radiology and the current status of radiation workers and radiation related workers. As for the satisfaction of the workers who were designated as frequent visitors while attending the department of radiology and did not handle and operate the radiation generator during on-campus training, 34.62% of the workers answered 'not satisfied'. On the other hand, 50% of workers who were designated as radiation workers while attending school or who were enrolled in school before the regulation of the nuclear safety act and handled and operated radiation generators were 'satisfied' at 50%. In addition, the annual exposure dose of radiation workers in educational institutions was found to be less than 0.05 mSv. If you look at the trends of radiation workers and radiation workers, it can be seen that students who graduate from the Department of Radiology find the most employment in the field dealing with diagnostic radiation generators registered as radiation workers among medical institutions. Therefore, by easing the regulations of the current Nuclear Safety Act or by amending the medical act and the rules on the safety management of diagnostic radiation generating devices, etc. It is presumed that something is necessary.

Flood frequency analysis commonly used to design the hydraulic structures to minimize flood damage includes uncertainty. Therefore, the most appropriate design flood within a uncertainty should be selected in the final stage of a hydraulic structure, but related studies were rarely carried out. The total expected cost function introduced into the flood frequency analysis is a new approach for determining the optimal design flood. This procedure has been used as UNCODE (UNcertainty COmpliant DEsign), but the application has not yet been introduced in South Korea. This study introduced the mathematical procedure of UNCODE and calculated the optimal design flood using the annual maximum inflow of hydroelectric dams located in the Bukhan River system and results were compared with that of the existing flood frequency. The parameter uncertainty was considered in the total expected cost function using the Gumbel and the GEV distribution, and the Metropolis-Hastings algorithm was used to sample the parameters. In this study, cost function and damage function were assumed to be a first-order linear function. It was found that the medians of the optimal design flood for 4 Hydroelectric dams, 2 probability distributions, and 2 return periods were calculated to be somewhat larger than the design flood by the existing flood frequency analysis. In the future, it is needed to develop the practical approximated procedure to UNCODE.
