Hydrogen peroxide has been used in cleaning the piping of an advanced high-purity water system that supplies ultra-high purity water (UHPW) for 16 megabyte DRAM semiconductor manufacturing. The level of hydrogen peroxide-resistant bacteria in UHPW water was monitored prior to and after disinfecting the piping with hydrogen peroxide. Most of the bacteria isolated after hydrogen peroxide disinfection were highly resistant to hydrogen peroxide. However, the percentage of resistant bacteria decreased with time. The hydrogen peroxide-resistant bacteria were identified as Micrococcus luteus, Bacillus cereus, Alcaligenes latus, Xanthomonas sp. and Flavobacterium indologenes. The susceptibility of the bacteria to hydrogen peroxide was tested as either planktonic cells or attached cells on glass. Attached bacteria as the biofilm on glass exhibited increased hydrogen peroxide resistnace, with the resistance increasing with respect to the age of the biofilm regrowth on piping after hydrogen peroxide treatment. In order to optimize the cleaning strategy for piping of the high-purity water system, the disinfecting effect of hydrogen preoxide and peracetic acid on the bacteria was evaluated. The combined use of hydrogen peroxide and peracetic acid was very effective in killing attached bacteria as well as planktonic bacteria.

본 연구에서는 라즈베리파이에 부착된 카메라로 사람을 얼굴을 인식하는 영상처리기법을 활용하여 가정용 로봇을 제작하였다. 라즈베리파이에 부착된 카메라를 통해 실시간으로 영상을 입력받아서 사람의 얼굴을 인식하게 한 후 결과에 따라 스마트냉온풍기의 동작을 구분한다. 이는 로봇이 사람이 없는 곳에 냉온풍기를 동작하지 않고, 사람이 있는 곳에만 냉온풍 동작을 하게 함으로써 에너지 활용 효율을 높일 수 있을 것으로 기대된다.

Objectives: This study examines the foodservice status of kindergartens attached to elementary schools in Seoul. We further determine the perception of elementary school principals and kindergarten assistant principals on the foodservice management for kindergartens. Methods: This survey was conducted from July 17 to 23, 2019, enrolling 207 kindergartens attached to elementary schools in Seoul. Questionnaires were sent to principals of elementary schools and assistant principals of kindergartens, and the data obtained from 89 kindergartens were included in the analysis. The questionnaire consisted of four parts: general information on subjects, foodservice management status, foodservice management status during elementary school vacations, and the perception of principals of elementary schools and assistant principals of kindergartens on foodservice management. Data are presented as frequency and percentage or mean and standard deviation. Statistical comparison between principals of elementary schools and assistant principals of kindergartens was conducted by paired t-test, chi-square test, and Pearson's correlation analysis. Results: A separate menu (10.1%) or recipe (20.2%) that considers preschooler characteristics was rarely used for foodservice at kindergartens attached to elementary schools. Most kindergartens did not have a separate dining space (3.4%) or a dedicated cook (93.3%). Although most kindergartens (92.1%) had operational foodservice during elementary school vacations, non-professional staff and non-nutrition teacher were mainly in charge of organizing the menu and purchasing ingredients (34.1% and 41.5%, respectively). The rate of using a contract catering company (28.0%, 23.2%) was also high. Both elementary school principals and assistant principals of kindergartens showed a high perception of the necessity for providing responsibility allowances for nutrition teachers and improving the cooking environment for kindergartens during elementary school vacations. Conclusions: There is a need for policies and administrative support measures to improve the quality of foodservices for kindergartens attached to elementary schools.

In this study, we investigated whether the theorem is established even if we replace a 'square' element in the Euclidean proof of the Pythagorean theorem with different figures. At this time, we used different figures as equilateral, isosceles triangle, (mutant) a right triangle, a rectangle, a parallelogram, and any similar figures. Pythagorean theorem implies a relationship between the three sides of a right triangle. However, the procedure of Euclidean proof is discussed in relation between the areas of the square, which each edge is the length of each side of a right triangle. In this study, according to the attached figures, we found that the Pythagorean theorem appears in the following three cases, that is, the relationship between the sides, the relationship between the areas, and one case that do not appear in the previous two cases directly. In addition, we recognized the efficiency of Euclidean proof attached the square. This proving activity requires a mathematical process, and a generalization of this process is a good material that can experience the diversity and rigor at the same time.
