Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.

Purpose: This study was to identify knowledge, perception and health behavior about metabolic syndrome for an at risk group in a rural community area. Methods: A descriptive cross-sectional survey design was used. A total of 575 adults with hypertension, diabetes mellitus, dyslipidemia, and/or abdominal obesity were recruited from 11 rural community health care centers. A questionnaire was developed for this study. Anthropometric measures were measured and blood data was reviewed from the health record. Results: Knowledge about the metabolic syndrome was low as evidenced by only a 47% correct answer rate. Only 9% of the subjects ever heard about the disease, and 87% answered they do not know the disease at all. 87% of the subjects were not performing regular exercise, 31% drank alcohol more than once a month, 12.5% were current smokers, and 33.6% are did not have a regular health check-up. Conclusion: Development of systematic public health care programs are needed to prevent future increases in cardiovascular complications and to decrease health care costs. These might include educational programs for the primary health care provider and an at risk group, a therapeutic lifestyle modification program, and a health screening program to identify potential groups.

We would like to suggest the guideline of use of materials of sexual education for adolescent in school by examining the status of use of materials and by evaluating the video materials frequently used. Survey was done by enquetes on status of use of materials of sexual education from school nurses in 190 primary, 44 middle and 50 high schools in Seoul, Kyonggi-do and Kangwon-do from August 1999 to February 2000. The frequently used 84 videotapes were evaluated on their contents. As for the status of use, 99.3% of subjected schools possessed the materials for sexual education. Decision of purchase was determined according to the review of contents (92.6%). Information about materials was received by the advertisement in newspapers or broadcasting (46.1%) or recommendation of peer teacher (32.4%). Videotape was most frequently used (64.1%) rather than books or CD. Teachers concerns on the materials were the educational content according to developmental stage of students (41.9%), content provoking interest (33.5%) and concrete guide for teacher (10.6%). As for the evaluation of the contents of videotapes, a subject of education was not described out of 46.6%. Videotape producer were mostly the Government-affiliated institutes or non-profit organizations (86.8%). The year of production was indicated from 41.7%. Running time range of 21-30 minutes was highest (55.9%). The price was marked in only one videotape. Subjects of contents were general sexual education (34.5%), sexual violence or sexual harassment (21.4%), pregnancy and contraception (14.2%) and AIDS and sexually transmitted diseases (8.3%) and dating and adolescent change (4. 8%), and etc (11.9 %). According to above results, we suggested that materials for sexual education should be completed with a description on the subjected group, summary of content, information on the tape producer, year of production, running time and sale price.

Objectives: To investigate the current status and challenges of research methodology for health promotion research (HPR), this study analyzed HPR funded by the Korea Health Promotion Foundation (KHPF) from 2005 to 2011. Methods: All of the research reports funded by the KHPF for the period were included in this study. From the literature reviewed, a framework of this study was developed. Results: Quantitative research was 67.7%. The most common quantitative research design was cross-sectional survey (46.6%). Only 7.3% of quantitative research employed theoretical frameworks, and more than a half (53.4%) used primary data. For qualitative research (2.8%), most cases were conducted together with quantitative research. No qualitative research employed a philosophical underpinning. Only 7.0% of research received consent form, and 2.1% was approved by institutional review board. The results of this study indicate that there is a need to employ various research methods to study key concepts of HPR more in-depth. Efforts should be made to reduce statistical errors and also employ newly introduced statistical methods. Conclusions: Overall, a lack of scientific evidence from the HPR reports analyzed in this study was observed. Therefore, the KHPF and the academia should work together to solve the problems indicated from this study.

The purpose of this study was to establish a conceptual management spectrum framework for integrated management of Baekdudaegan area. The conceptual model was developed through a literature survey that includes the concepts from existing relevant systems and other expert sources In conceptual Baekdudaegan management spectrum framework presented here, three different classes (preservation, buffer, and multiple-use) that specify potential management objectives for area functions were classified in order to pursue management flexibility Three primary management classes should be identified by evaluating Indicators of ecological, physical, and social.cultural environments. An application of the framework requires an explicit selection of indicators and their evaluation. For establishing reliability of the framework, it will be desirable to test it empirically in Baedudaegan areas in the future. In addition, systematic case study for selecting appropriate indicators and identifying evaluation standards must be done.

Wastewater treatment plants (WWTPs) with activated sludge system are widely used throughout the most common technologies in the world. Most treatment plants require optimization of certain treatment processes using dynamic modeling. A lot of examples of dynamic simulations require reliable data base of diurnal variation of the inflow and typical concentrations of parameters such as Chemical Oxygen Demand (COD), Total Kjeldahl Nitrogen (TKN), etc. Such detailed data are not available, which leads to problemsin the application of dynamic simulations. In many examples of plants, continuous flow measurements are only performed after the primary clarifier, whereas measurements from influent to the plant are missing, as is the case with the examples in this paper. In some cases, a simpler, faster and cheaper way can be applied to determine influent variations, such as the "HSG-Sim" method ("Hochschulgruppe Simulation"). "Hochschulgruppe Simulation" is a group of researchers from Germany, Austria, Switzerland, Luxembourg, Netherlands and Poland (see http://www.hsgsim.org). This paper presents a model for generating daily variations of inflow and concentration of municipal wastewater quality parameters, applied to several existing WWTPs in Bosnia and Herzegovina (B&H). The main goal of the applied method is to generate realistic influent data of the existing plants in B&H, in terms of flow and quality, without any prior comprehensive survey and measurements at the site. The examples of plants show the influence of overflow facilities on the dynamics of input flow and quality of wastewater, and a strong influence of the problems of the sewerage systems.

This study purposed to discover whether or not academic libraries reflect these changing roles. We selected K University as the research target and surveyed user satisfaction of materials, staff services, facilities, electronic devices, media, and so on. The research findings are as follows: 1) the frequency of library visits of University K was on the high side, 2) the primary purpose of using the academic library was associated with learning or reading, therefore, the most used library spaces were related to that, 3) the most used library materials were 'general books', the most unused were 'reference books', 4) the most preferred way to obtain needed materials when failing to find wanted materials was 'Contact librarian'. A similar phenomenon occurred in terms of facility use, 5) university K's users were usually satisfied with the loan policy, 6) the rate of users who don't know whether there is user education was very high, the rate of users who have no experience with user education was extremely low. These research findings can be referenced by library management to improve libraries' service quality and take advantage of complex spatial configurations.

Purpose: The aim of this study is to identify the types of gambling among adolescents and provide basic prevention information regarding adolescents' gambling problems. Methods: Secondary data from representative national survey on 2015 Youth Gambling Problems of Korea Center on Gambling Problems were used. Using latent class analysis (LCA), 13 gambling types such as offline and online games of 14,011 adolescents were classified, and gambling experiences and characteristics were analyzed. Results: The subgroups of adolescent gambling were identified as four latent classes: a rare group (84.5% of the sample), a risk group (1.0%), an offline group (11.9%), and an expanded group (2.6%). The types and characteristics of gambling among the latent classes differed. In the risk group, adolescents participated in online illegal sports betting and internet casino, and gambling time, gambling expenses, and the number of gambling types were higher than other groups. Conclusion: Gambling frequently occur among adolescent, and the subtypes of gambling did not reveal homogeneous characteristics. In order to prevent adolescent gambling problems, it is a necessary to develop tailored prevention intervention in the nursing field, which is appropriate to the characteristics of adolescent gambling group and can help with early identification.

Cleft lip and palate are most common congenital defomity to affect the orofacial region. Cleft lip and palate are caused by abnormal development of primary and secondary palate. Its causative mechanism is not completely understood, but genetic and environmental factors play important roles. Lots of epidemiologic surveys have been done extensively about incidence, racial influence, sex ratio, parent age, associated syndrome and genetic factors. These researches are useful to dissolve many problems in prevention and treatment of cleft lip and palate. We performed epidemiologic survey of cleft lip and palate who visited the department of Oral and Maxillofacial Surgery, Guro hospital of Korea University from 1995 to 2004.

The common-envelope process is a complicated phase in binary evolution. A lot of effort has been dedicated to study the common-envelope stage, but many questions related to this process are yet to be answered. If one member of the binary survives the common-envelope phase, the binary will emerge as a white dwarf accompanied by a low-mass main sequence star in close orbit, often referred as a post common-envelope binary (PCEB). SDSS J0745+2631 is among the list of newly found PCEBs from the Sloan Digital Sky Survey (SDSS). This star is proposed to be a strong eclipsing system candidate due to the ellipsoidal modulation in its light curve. In this work, we aim to confirm the eclipsing nature of SDSS J0745+2631 and to determine the stellar and orbital parameters using the software Binary Maker 3.0 (BM3.0). We detected the primary eclipse in the light curve of SDSS J0745+2631 in our follow-up observation from January 2014 using the ULTRASPEC instrument at the Thai National Observatory. The data obtained on 7th and 8th January 2014 in g filter show an evident drop in brightness during the eclipse of the white dwarf, but this eclipse is less prominent in the data taken on the next night using a clear filter. According to our preliminary model, we find that SDSS J0745+2631 hosts a rather hot white dwarf with an effective temperature of 11500K. The companion star is a red dwarf star with a temperature of 3800K and radius of 0.3100 $R_{\odot}$. The red dwarf star almost fills its Roche lobe, causing a large ellipsoidal modulation. The mass ratio of the binary given by the Binary Maker 3.0 (BM3.0) model is M2/M1 = 0.33.
