Background: Human papillomavirus (HPV) is one of the most common sexually transmitted infectious agents, and the effectiveness of vaccine delivery programs will depend largely upon whether providers recommend vaccines. The objectives of this study were to examine pediatrician characteristics, knowledge, and attitudes associated with HPV and HPV immunization. Materials and Methods: Attendees of the national pediatric meeting in 2011, were asked to complete a questionnaire that, aside from demographic information, elicited level of agreement with statements regarding HPV, its related diseases, and HPV vaccination. It also documented attitudes and beliefs about HPV vaccination. Results: Of the 480 attendees, 226 (47%) filled in the questionnaire. The level of pediatrician HPV-related knowledge varied. The majority (78%) were aware that HPV infection is the most common sexually transmitted infection, while 51% were unaware that a condom is ineffective protection against HPV infection. Between 60-80% of respondents were aware of the effectiveness of HPV vaccination for women. On the other hand, only 10% were aware of reasons why men should be vaccinated against HPV. The majority (75%) of Turkish pediatricians were likely to recommend HPV vaccination to their daughter, if they had one. Seventy percent of pediatricians agreed that the HPV vaccination should be added to the National Immunization Program (NIP) in Turkey. However, the respondents documented concerns about the cost of the vaccination. Conclusions: Increasing pediatricians' knowledge and awareness of HPV and HPV vaccination may assist with the implementation of an effective NIP.

The antimicrobial activity of 70% ethanol extracts from Rosa multiflora Thunberg fruit against Helicobacter pylori was examined. The inhibitory activity of Rosa multiflora Thunberg fruit extracts against H. pylori was determined to clear a zone of 14 mm with 70% ethanol extracts. Purification of inhibitory compounds was carried on Sephadex LH-20 and $C_{18}$ cartridge column chromatography using a gradient procedure, with increasing ethanol ($0{\rightarrow}100%$) in $H_2O$. The chemical structure of the purified inhibitory compounds on H. pylori was identified to be protocatechuic acid, chlorogenic acid and quercetin by FAB-MS, NMR and IR spectrum.

This thesis develops a fuzzy-PID control algorithm for control the filament winding tension. It is developed by applying classical PID control technique to a fuzzy logic controller. It is composed of a fuzzy-PI controller and a fuzzy-D controller. The fuzzy-PI controller uses error and integrated error as inputs, and the fuzzy-D controller uses derivative of error as input. The fuzzy-PI controller uses Takagi-Sugeno fuzzy inference system, and the fuzzy-D controller uses Mamdani fuzzy inference system. The fuzzy rule base for the fuzzy-PI controller is designed using 19 rules, and the fuzzy rule base for the fuzzy-D controller is designed using 5 rules. A test-bed is set-up for verifying the effectiveness of the developing control algorithm in control the filament winding tension. It is composed of a mandrel, a carriage, a force sensor, a driving roller, nip rollers, a creel, and a real-time control system. Nip rollers apply a vertical force to a filament, and the driving roller drives it. The real-time control system is developed by using MATLAB/xPC Target. First, experiments for showing the inherent problems of an open-loop control scheme in a filament winding are performed. Then, experiments for showing the robustness of the developing fuzzy-PID control algorithm are performed under various working conditions occurring in a filament winding such as mandrel rotating speed change, carriage traversing, spool radius change, and reference input change.

The Committee on Infectious Diseases of the Korean Pediatric Society recommended immunization schedule for children and adolescents aged 18 years or younger in the 9th (2018) edition of Immunization guideline. This report provides the revised recommendations made by the committee and summarizes several changes from the 2015 guideline. National immunization program (NIP) launched a human papillomavirus (HPV) immunization for girls aged 12 years in 2016. NIP has also expanded age indication for inactivated influenza vaccine (IIV) to 12 years of age in the 2018-2019 season. Quadrivalent IIVs with a full dose (0.5 mL) are approved for all children of 6 months or older. Recommendations of live attenuated influenza vaccine were removed. For inactivated Japanese encephalitis vaccine, first 2 doses are considered as the primary series. Recommendations for use of newly introduced vaccines (diphtheria-tetanus-acellular pertussis/inactivated poliovirus/Haemophilus influenzae type b, 9-valent HPV, new varicella vaccine, new quadrivalent IIV, and attenuated oral typhoid vaccine) were added. Lastly, monitoring system for adverse events following immunization was updated. Other changes can be found in the 9th edition of Immunization guideline in detail.

The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studios middle school textbooks. Data were collected through national curriculum documents and social studies middle textbooks for 7-9 grades. We set up three questions for this studies; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) Photographs, illustrations, information maps, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, circle graphs, and stripe graphs nip often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not so good, especially in the curriculum steps of information mads scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics are needed for social studies teachers.

This study was carried out to analyze characteristics of water quality and correlation among water quality parameters in Idong reservoir used for agricultural water. The pH and concentrations of DO, SS, BOD, COD, TP, Chl-a in Idong reservoir almost met the water quality standards for agricultural water, but TN concentration exceeded the water quality standards for agricultural water. All of water quality items had no significant difference between horizontal points at 95% confidence level and the Idong reservoir was possible to be treated as the single water body. As NIP ratio of the Idong reservoir is 52, TP is a limiting nutrient salt. As TN exceeds the water quality standards, it is required to preserve TP below current state to prevent water bloom by eutrophication. Therefore, reduction of phosphorus from the watershed is necessary for controlling the eutrophication of Idong reservoir.

Biaxially oriented polyethylene terephthalate copolymer(BO - PET)film laminated aluminiums have been applied for chip condenser case. The BO PET film is characterized by high molecular which gives high corrosion resistance, good adhesion and high heat resistance. The higher orientation lowers formability of the film. So, optimum orientation has to be controlled during the laminating process. And to confirm the adhesion between BO PET and aluminium and to guarantee the formability of PET laminated aluminums, we have controlled the chromium oxides weight on the aluminium and laminating condition ( laminating temperature, soaking temperature and lag time after nip roll and quenching conditions) This paper discusses the effect of the laminating conditions on the formability of laminated aluminums. As results, it is clear that the orientation of the BO PET film decreased with an increase in the strip temperature. When the film temperature is over the melting point of the film, its orientation drastically decreased.
