Purpose: The aim of this study was to evaluate the efficiency of the Humpty Dumpty Falls Scale as one of the falls risk assessment tools, and also to evaluate risk factors as predictors of falls in pediatric patient populations. Methods: In a retrospective, case-control design with data from the electronic medical records of 13 pediatric patients who fell and 1,941 who did not fall before matching and 429 who did not fall after matching by gender, age, diagnosis, and length of stay. Results: All the variables showed no significant differences after matching. At the cutoff score of 13, sensitivity, specificity, negative and positive predictive values were 92.3%, 37.1%, 99.9%, and 0.01%, respectively. The area under the Receiver Operating Characteristics was 0.597. The results from the logistic regression showed that the pediatric inpatient population who had higher risk scores was significantly associated with falls. The odds ratios ranged from 1.31 to 4.71 with 90% confidence interval. Conclusion: The saturation impairments criterion as one of the diagnostic parameter was negatively associated with falls, but the relative risk score was higher than the other criteria. Therefore, it seems that the diagnostic parameter seems to be required to verify results through large sample studies.

Recently, the number of cases of fire spreading due to exterior materials of buildings is increasing. Due to the nature of modern architecture, which emphasizes the aesthetics of buildings, because buildings pursue a splendid appearance, they are inexpensive and have relatively good insulation performance, but an increasing number of buildings are adopting insulation materials that have poor fire safety performance. The risk of spread is also greatly increased. Since the exterior wall of a building is made of a variety of materials and structures, it is composed of a combination of several elements, including materials such as insulation and finishing materials. Therefore, it was determined that it was necessary to introduce a more systematic evaluation method for building exterior materials, and to improve the system reflecting this, away from the existing evaluation method that only checked the fire safety performance of finishing materials.

우리나라는 서울지역과 수도권 위성도시의 인구분포가 집중되어있으며, 도시지역에 대한 관거 우선 확충에 따라 하수처리구역의 비율이 점차 늘어나고 있다. 초기우수월류에 의한 오염은 비점오염원의 경우로, 발생 및 배출경로가 다양하고 불특정하게 발생한다. 비점 오염원의 유출 농도는 강우 초기에 높게 나타나고, 점차 농도가 낮아지는데, 이러한 강우 특성을 고려하여 오염발생량을 규명하는 것이 필요하다. 이에 따라 본 연구에서는 중랑천 의정부 지역을 대상지역으로 선정하여, 합류식 하수관거 월류부하를 하수도법 관리수준으로 제어하기 위한 초기우수 처리대상 강우량을 산정하고 강우분포형 및 토지이용도 현황별로 초기월류유량 및 부하특성을 검토하였다. 본 연구에서는 SWMM(Strom Water Management Moder)모형을 적용하여, 매년 홍수기에 발생할 수 있는 다양한 강우분포를 고려하여 대상유역의 토지용도별 합류식 처리구역에 대하여 SWMM 모형의 검·보정 절차를 통해 예측값과 측정값 사이의 상관관계를 분석하였고, 의정부 지역의 초기우수월류 오염부하량의 토지용도에 따른 경향성과, 강우량 및 강우분포, 배수면적에 따른 경향성을 비교하였다.

Background: The aim of this study was to comparatively evaluate the bactericidal effects of copper, brass (copper 78%, tin 22%), and stainless steel against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium (VREFM), and multidrug-resistant Pseudomonas aeruginosa (MRPA). Methods: The isolates (MRSA, VREFM, MRPA) used in this study were mixed wild type 3 strains isolated from patients treated at Uijeongbu St. Mary's Hospital in 2017. These strains showed patterns of multidrug resistance. The lyophilized strains were inoculated into and incubated for 24 hr in tryptic soy broth at $35^{\circ}C$. The initial bacterial inoculum concentration was adjusted to $10^5CFU/mL$. A 100-mL bacterial suspension was incubated in containers made of brass (copper 78%, tin 22%), copper (above 99% purity), and stainless steel at $35^{\circ}C$. Viable counts of bacteria strains were measured for 9 days. Results: In this study, the bactericidal effects of copper and brass on MRSA, VREFM, and MRPA were verified. The bactericidal effect of stainless steel was much weaker than those of copper and brass. The bactericidal effect was stronger on MRPA than on MRSA or VREFM. Conclusion: To prevent cross infection of multidrug resistant bacteria in hospitals, further studies of longer duration are needed for testing of copper materials on objects such as door knobs, faucets, and bed rails.

The author has arrived at the following result after having carried out multilateral study based on a total of 282 maxillofacial fracture patients who have receive treatment at the Euijeongbu general hospital and Shinchun general hospital in the northern district of Kyunggido from march 1988 to august 1990. 1. Sex distribution of Mx. facial fx. patient was higher in male by 4.6:1 and was predominant in the 3rd decade with 40.4% followed in decreasing order by the 2nd decade and the 4th. 2. A majority were in the Mn. with 40.2% followed in decreasing order by zygoma. nasal bone and maxilla. 3. For the sex distribution according to anatomy, make to female ratio was 6.2:1 in the mandible, followed in decreasing order by zygoma, and nasal bone with predominance in male. 4. Car accident with 42.8% was the most common cause of fx. followed in decreasing order by violence, workmen's accident, and fall down. 5. The involvement of other trauma areas are head. 79.0%, abdomen-thorax, and the extremities in decreasing order. 6. In the mandibular fx. a majority were in the symphysis with 73.9% followed in decreasing order by angle, Condyle, and body. 7. Maxillary fx. of the type LeFort II was estimated to be 41.2% 8. Fracture in the zygoma including zygomatic arch was estimated to be 72.5%

지난2001년출범한한국과학기술정보연구원(KISTI)은현재국내외적으로가장주목받는과학기술정보유통분야의연구기관이다. 출범1년만에공공기술분야의정부출연기관중경영성과1위에오른것을비롯해 과학기술정보유통분야의선진국이라고자부하는일본에서도이기관이구축한시스템을벤치마킹하기도했다. 불과5년이라는짧은기간에정상에올라설수있었던것은KISTI 구성원들의열정과노력이있었기때문. 그런데 KISTI 에서는 유독‘ 독종’, ‘ 불도저’등으로 불리는 인물이 있다. 주인공은 지난달 퇴임한 조영화 전KISTI 원장이다. 업무추진력이뛰어나고, 일단시작한일은반드시마무리를해야하는성격탓에붙은별명. ‘ 용장밑에약졸없다’는고사는조전원장과KISTI 직원들에게딱어울리는말이다.

The purpose of this study was to investigate the semantic network analysis to understand image contents and to examine the degree to which words, word clusters contributed to the formation of semantic map within image contents. For this research, from 1993 until 2016 the field of the image contents were collected for a total of 2,624 cases papers. The word appeared in Title analyzed the social network by using the R program of Big Data. The results were as follows: First, The field of image contents is based on researches related to 'image', 'media' and 'contents'. Second, there is a three-step flow ('education' -> 'media' -> 'contents') of research in the field of image contents. Third, researches related to 'broadcasting', 'digital', 'technology', and 'production' were continuously carried out. Finally, There were new research subjects for each regime.

Pilotis are support columns that lift a building above the ground. Thus, they can elevate the lowest floor to the secondfloor level and, in Korea, are used to leav a parking area below multifamily housing. However, if there is a fire in the piloti area, the cars and main entrance door are wrapped in flames. Due to the inflammability of the materials, the combustion of the cars and insulation at the ceiling of the pilotis, having a high heat release rate, can quickly destroy the front entrance of the building and spread heat, flames and a poisonous gas to the stairs and elevator pit. Therefore, the fire can quickly spread to the whole building, putting the lives of the residents in danger. This study was an in-depth accidental case study of the "Uijeongbu Fire Accident" that killed 5 residents and injured 139 others. The study identified the relationships between the fire at the piloti structure of multifamily housing and the vulnerability of this structure and its inherent weaknesses.

The Jurassic granites, commercially called Yangu stone in the Pocheon-Euijeongbu area, have generally compact and coarse-grained textures, which could be classified into two types; grey granite(Gg) and light pink granite(Gp). Specific gravity, absorption ratio and prosity of Gg and Gp in physical property are 2.64 and 2.61, 0.32 % and 0.44 %, 0.86% and 1.13 %, respectively. These higher values of two latters of Gp than those of Gg are due to the more abundant microcracks in Gp. Compressive strength og Gg than those of Gg are due to more abundant microcracks in Gp. Compressive strength og Gg and Gp are 1,726 kg/cm2 and 1,717 kg/cm, respectively and bestrength has a positive proportion with Qz+Af+Pl(quartz+alkali feldspar+plagioclase) modes without trending with Bt+Ac(biotite+accessories). Tensile strength has the positive proportions with Qz+Af+Pl and Bt+Ac. While Bt+Ac has a negative trend with abrasive hardness, Qz+A+Pl shows a positive one. These may suggest Qz+Af+Pl mainly affects on strenghts potentional dimension stone than Gp.
