홍수피해 발생 시 각 지역의 특성에 따라 피해의 정도가 다르게 나타나고 있다. 도시지역의 경우 포장도로로 인하여 불투수 면적이 넓어 배제 시설의 허용 용량을 초과하는 강우 발생 시 지표면 위로 유량이 누적된다. 특히 농촌지역에 비해 도시지역에서 국지적으로 기습적인 강우에 빈번히 침수피해가 발생한다. 우리나라 도시지역은 인구와 건물이 밀집되어 재산과 인명피해 및 교통체증 등으로 인한 간접피해 등 농촌지역에 비해 더 큰 피해가 발생할 수 있다. 도시 지역의 침수 피해 저감을 위해 우수 유출 저감시설과 내수배제 시설을 설치하여 우수의 유출을 지연시키거나 인위적으로 방류부 하천으로 방류시키는 방법이 있지만 이러한 시설의 설치에는 막대한 비용이 필요하며, 내수배제시설이 설치된 장소에 따라 침수현상이 다르게 나타나 저감시설 설치 전 공간적, 효율적으로 설치 가능한 장소와 침수 저감 효율에 대한 분석이 필요하다. 본 연구는 도림1 배수분구를 대상으로 XP-SWMM모델을 이용하였으며, 2010년 09월 21일 침수 발생 당시의 강우를 적용하여, 연구대상지역의 도시유출해석을 진행하였다. 또한, 어린이 공원과 학교운동장에 가상지하저류조를 설치하였을 시 침수저감 효과에 대하여 연구를 진행하였으며, 다양한 지하저류조 설치 시나리오에 따른 침수저감효과를 수심별 침수면적으로 나타내어 분석을 실시하였다. 본 연구를 통해, 도심지 지하 저류시설 도입의 기초자료로 활용될 수 있을 것으로 판단된다.

This study researched the spawning sites of Kaloula borealis in a large number of wetlands in Jeju Island between May and August from 2007 to 2010. Based on the surveys, we discovered the locations of their habitats by investigating their calls from a rainy night to the next day and where their spawning sites were by ascertaining the existence of their eggs and tadpoles. According to the results, 83 wetlands were used as spawning sites across Jeju Island. A large number of wetlands were found to be permanent wetlands for Kaloula borealis. In addition, 81.9% of the wetlands in Jeju Island were found to be at an altitude of 150m or lower, and they spawned in shallow water not more than 50cm in depth. By region, 54 wetlands were in Jeju-island 29 wetlands were in Seogwipo-si. One of the reasons that Seogwipo-si has less wetlands than Jeju-si is that there are more orchards in Seogwipo-si than Jeju-si; accordingly, wetlands in Seogwipo-si were found to be more destroyed by farming. In the case of Seongsan-eup, a reedy marsh stretches out widely so that spawning sites were well preserved compared to other regions. This research will provide useful data for sustaining the population of Kaloula borealis by protecting their spawning sites from development, by offering habitats, and restoring spawning sites, which have become severely damaged and destroyed.

In this study, we classified word problems related to real life presented in elementary mathematics textbooks into five types of context problems(location, story, project, scrap, theme) suggested by Freudenthal(1991), and applied context problems to mathematics class to analyze the influence on students' mathematical belief and attitude. Also, we examined the types of context problems preferred according to academic performance and the reasons of preference within a group experiencing context problems. The results of the study are as follows. First, almost lessons in the mathematics textbook presents word problems related to real life, but the presenting method is inclined to a story type. Also, the problems with a story type are presented fragmentarily. Therefore, although these word problems are familiar to the students, they don't include contextual meanings and cannot induce enough mathematical motives and interests. Second, a lesson using context problems give a positive influence on their mathematics belief and attitude. It is also expected to give a positive influence on students' mathematics learning in the long run. Third, the preferred types of context problems and the reasons of preference are different according to the level of academic performance within the experimental group.

The purpose of this study was to analyze the patients hospitalized with damage by injury code based on data for two years in 2020 and 2021 of A institution located in Gangneung, Gangwon-do. Analyzed the injury codes with a large number of occurrences per year, and analyzed the injury codes of external causes accordingly. The cause of the injury code was analyzed by analyzing the frequency of the injury code of external causes. Injury code S0650 had the highest frequency of injury code of external causes W189 and X5999, which was judged to be the cause of traumatic subdural hemorrhage without open intracranial wounds when falling in an unspecified place or toilet. Injury code S72120 had the highest frequency of injury code of external causes W010 and W180, and it was judged to be the cause of obstructive femoral intertrochanteric fracture that occurs when falling in the residence. The injury code S32090 had a high frequency of X5999, and it was analyzed that it caused the obstructive fracture of the lumbar region due to an accident caused by exposure in an unspecified place, and the injury code S72.090 had a high frequency of W010 and W180. It was confirmed that the cause of the obstructive fracture of the femoral neck was mainly caused by slipping or slipping in the residence, and the injury code S0220 had a high frequency of the injury code of external causes Y049, and it was confirmed that the fibula was fractured mainly by the force or fist. As such, the cause of the injury code was analyzed by analyzing the frequency of the injury code for each injury code of external causes.

This study explores the transfer of defunct school records (by preservation period, type, and place of transfer) in South Korea since the Public Records Management Act was enacted in 1999 and suggests improvements. Metropolitan and provincial offices of education, totaling 17, were asked to disclose information about the status of defunct school records. Since 1999, 1,411 schools nationwide have closed permanently, predominantly elementary schools, followed by high then middle schools. By preservation period, there were more records in the 1 to 10-year category than in the 30-year to permanent category. By record type, most were electronic records, followed by paper records, archival objects, and audiovisual records. By place of transfer, most nonelectronic records were transferred to integrated schools, and most electronic records were transferred to the Records Management System. In-depth interviews with 10 record managers from local education offices found that the management of defunct school records varies widely by region and institution because of the lack of specified manuals. Participants also reported difficulties in transferring web-based records, archival objects, and audiovisual records, as well as insufficient archival space and computer systems. This study also provides suggestions to improve the management of defunct school records, such as establishing specified manuals, creating a dedicated government department for managing defunct school records, deploying workforces, and improving computer systems.

Purpose: This study examined whether there was a difference in the nutrients and food intake of young children depending on their lunch places. Methods: The dietary survey data of the fifth Korea National Health and Nutrition Examination Survey (2010 ~ 2012) were used. The children were grouped into either a child care center lunch group (n = 728) or home lunch group (n = 592) and their nutrients and food intakes were compared. Results: No differences in the 24-hr energy intake and energy intakes from lunch and dinner according to the lunch places were observed. The percentage of breakfast energy was lower in the child care center lunch group, whereas the percentage of snack energy was higher. In children aged 3 ~ 5 years, the sodium, potassium, and vitamin C intakes were high in the child care center lunch group. The 1 ~ 2 years and 3 ~ 5 year old children's vegetable intake from lunch was significantly higher in the child care center lunch group than in the home lunch group. Children aged 3 ~ 5 years in the child care center lunch group consumed more beans and fish at lunch. The adequacy of nutrients and food diversity of child care center lunch appear better than home lunch. Conclusion: Parents and care providers need to make efforts to use diverse foods, such as vegetables and fish, in children's meals to provide balanced diets and promote healthy eating behaviors to their children.

B2B registries are information systems to register B2B related business information such as companies' profiles, business documents, business processes, and services and to provide query facilities to find information about potential business partners. Focusing on the design of the registry for B2B business processes, in this paper, a metadata ontology is designed to register B2B business processes. In practice, there are several competitive business process definition languages such as ebXML BPSS (Business Process Specification Schema), WSBPEL (Web Service Business Process Execution Language), BPMN (Business Process Modeling Notation), and so on. In order to register heterogeneous business processes based on different representation frameworks, the proposed metadata ontology consists of three layers, common metadata, language-specific metadata, and interrelationship metadata. To show the usefulness of the proposed metadata ontology, two examples which are represented by ebXML BPSS and WSBPEL respectively are described in order to show how the proposed metadata ontology is used to registry B2B business processes. To implement the proposed metadata ontology using ebXML registry, metadata mapping scheme to ebRIM (ebXML Registry Information Model) is also suggested.

The microbiological examinations were conducted for the hygienic evaluation on three Korean restaurants during summer season in Busan, Korea. Total one hundred and sixty swabbed samples using sponge were collected from the surface of facilities and utensils at restaurants and total and coliform counts were measured. Also thirty- six air samples were collected at inside of three restaurants for measuring total, coliform, Staphy-lococcus and mold and yeast counts. All collected samples kept in an ice-packed box were transported to the laboratory and analyzed. The results demonstrated that most swabbed samples were highly contaminated with microorganisms and coliforms. The degree of contamination depended on the sampling sites. Averages of total counts of surface swab samples were ranged from not detectable to 2.14$\times\10^{9}$/200 $cm^{2}$, while those of coliforms from not detectable to 8.34$\times\10^{7}$/200 $cm^{2}$/200 $cm^{2}$. Microorganisms also detected from most agar strips of air samples for total, coliform, Staphylococcus and mold and yeast counts. The severely contaminated sites were floor, trench, water bottle, plastic drainer, rubber gloves, shelves, and unsealed wet towel. Those sites should be focused and controlled according to control Points of sanitation standard operating Procedures. Also, periodic microbiological examination in addition to visual examination should be applied on those highly contaminated sites for reducing risk of foodborne disease outbreak at restaurants
