선진 외국에서는 홍수예보 시스템 활용의 극대화를 위하여 홍수예 경보를 위한 정책적 가이드라인 및 홍수시 주민의 행동요령 등의 가이드라인을 제작하여 홍보를 하고 있는 실정이다. 그러나 국내에는 현재 홍수위험지도(홍수피해예상지도)의 홍보 및 주민 대피요령 등 홍수피해경감을 위한 정책적 대책이 매우 부족한 실정이다. 따라서 본 논문에서는 국내 외 홍수예 경보관련 법 제도의 변화과정 및 현행 홍수예보관련 법령의 내용을 분석하였으며, 홍수예 경보관련 기관의 구조체계를 분석하였다. 그 결과 우리나라의 홍수예보 정책은 통합된 홍수예보만을 위한 내용으로의 법적 편제가 필요하며, 정확하고 신속한 홍수예보를 위한 정책적 가이드라인이 필요함을 알 수 있었다. 또한 홍수예 경보 시스템의 활용을 극대화시키기 위해서 국가차원에서의 국민에 대한 홍수 예방 교육 및 홍보, 아울러 홍수위험지도를 이용한 홍수위험 지역의 주민에 대한 홍수대피요령 등의 내용을 포함한 가이드라인이 필요하다.

The purposes of this study were to analyze the effects of a marine leisure exhibition event(MLEE)'s appraisal attributes on visitors' satisfaction and repurchase behavior and thus provide fundamental information that facilitates developing effective marketing and operational strategies for a MLEE. In order to accomplish such purposes, this study employed a survey with a total of 300 visitors to a MLEE hosted by G Province. Questionnaires were developed on the basis of related studies and modified to reflect the study context. Then, such questionnaires were verified to be valid and reliable through content validity, exploratory factor analysis and internal consistency analysis. Valid 286 questionnaires were analyzed with correlation analysis and multiple regression analysis on significance level of .05. Following findings were derived from current study. First of all, the appraisal attributes of a MLEE had a significant effect on visitors' satisfaction and among them only the factor of event program had a unique relation with the levels of satisfaction. In addition, the appraisal attributes of the MLEE also had a significant effect on visitors' repurchase behavior and among them event program, transportation and employee factors had unique relations with the performance variable in order. In conclusion, all the research hypotheses that had been set up through previous studies were confirmed in this study.

Purpose. The objective of this study was to evaluate the behavioral response and assess the effectiveness of additional intranasal (IN) and submucosal (SM) administration of midazolam during pediatric sedation for dental procedure. Material and methods. Thirty-three cases of healthy (ASAⅠ), uncooperative children aged from 24 to 72 month old at pediatric dental clinic of Ewha Womans University Hospital were selected for this study. Children received oral chloral hydrate 50 mg/kg with hydroxyzine 1.0 mg/kg. After waiting for 45 minutes, midazolam 0.2 mg/kg was administrated via IN route and via SM route randomly maintaining 50% of $N_2O$. A pulse oximeter and a capnograph were used for measuring vital signs ($SpO_2$, PR, RR, $EtCO_2$) throughout the sedation. Behavioral response was evaluated as Quiet (Q), Crying (C), Movement (M) or Struggling (S) in every 2 minutes for 40 minutes. Results. There were also no statistically significant differences in vital signs of the two groups. The behavioral response for the first ten minutes during sedation was a statistically significant difference (P < 0.05) between the two groups. After the first ten minutes, it was revealed that there was no significant difference. Conclusion. This study demonstrated that the addition of IN midazolam to the combination of oral chloral hydrate with hydroxyzine and nitrous oxide/oxygen inhalation is as safe and effective as that of SM midazolam in pediatric sedation for dental procedure.

The purpose of this study was to examine how oral health literacy of mothers affect the oral health status of their preschool children. The subjects were 233 mothers and their preschool children who are between 5 and 6 years old. They were selected according to the convenience sampling method. The individual self-administered questionnaire was used for the mother's survey while the children were interviewed using structured questionnaire to examine their oral health status and behavior. According to study results, the number of decayed primary teeth and the number of decayed and filled primary teeth had a statistically significant negative correlation with the oral health literacy of the mother, the children's oral health knowledge, attitude and behavior (COHKAB), and the mother's oral health management behavior. Hierarchical multiple regression analysis was performed after including general characteristics variables, the COHKAB and the mother's oral health management behavior. Meanwhile, mother's oral health literacy had a statistically influence on children's oral health status. The higher the mother's oral health literacy level, the lower the number of decayed and filled primary teeth were. The findings suggest that efforts to improve the oral health status of preschool children should consider mother's oral health literacy as an important factor. Therefore, the effective intervention and education programs are necessary to enhance mother's oral health literacy.

Safety education delivered to construction workers in a lecture manner has limitations in concentration and immersion, so delivery power and interest are low. In order to improve unstable behavior through education and prevent safety accidents, it is necessary to change the paradigm to hands-on education. Purpose: Experiential safety education aims to contribute to preventing accidents for construction workers by quickly recognizing risks, improving emergency response skills, and verifying the effectiveness of pre- and post-learning. Method: Based on a survey of workers who experienced the same work environment as the actual construction site, an opinion survey on the pre- and post-safety experience education and a variable measurement tool were planned, and a research hypothesis was established. Results: The Bayesian theory and MC simulation analysis were used to analyze the structural equation model, and the change in construction worker behavior was confirmed through the intended safety (A), non-experiential education in the sub-area of anxiety (B), average, standard deviation, and minimum and maximum values. Conclusion: The effect of education and industrial accidents are reduced only when construction workers are motivated to participate.

Estrone such as estriol and estradiol can not be determined by votammetric methods, because these are electrochemically inactive in the potential windows for mercury drop electrode. Nitro-derivatives of estrone are electro active and nitration of estrone is accomplished by heating the solution involving estrone and sodium nitrite in a water-bath at $100^{\circ}C$ for 30 min. Such nitro-derivatives are determined directly by voltammetry. The electrochemical behavior for nitrated estrone was investigated by cyclic voltammetry. The trace estrone was determinated by differential pulse adsorptive cathodic stripping voltammetry. Nitrated estrone gives a well defined voltammetric wave at ca. - 0.61 V (vs. Ag/AgCl electrode). The electrochemical reaction was irreversible process in sodium borate buffer at pH 11 and nitrated estrone was strongly adsorbed on the surface of mercury electrode. The optimal experimental conditions for the determination of nitrated esterone were found to be 0.05 M sodium nitrate, 0.01 M sodium borate, pH 11.0, and an accumlation potential of 0.10 V (vs. Ag/AgCl). The detection limit was as low as $1{\times}10^{-9}M$ for estrone with 2 min accumulation time.

Pyrifluquinazon is classified with a quinazoline insecticide that regulates food intake by controling the feeding behavior acting on the endocrine or nervous system of pests such as aphids and white fly. To keep safety on pyrifluquinazon residues in agricultural commodities a simple, accurate and rapid analytical method was developed and validated using high performance liquid chromatograph (HPLC-UVD). The pyrifluquinazon residues acidified with 1% formic acid in samples were extracted with acetonitrile and partitioned with hexane subsequently to dichloromethane then purified with silica solid phase extraction (SPE) cartridge. The purified samples were detected using HPLC-UVD. The method was validated using apple and pear spiked with pyrifluquinazon at 0.02, 0.05 and 0.1 mg/kg and hulled rice, pepper, soybean at 0.05 and 0.1 mg/kg. Average recoveries were 70.5~107.9% with relative standard deviation less than 10%. The result of recoveries and overall coefficient of variation of a laboratory results in Gwangju regional FDA and Daejeon regional FDA was followed with Codex guideline (CODEX CAC/GL 40). This method is appropriated at pyrifluquinazon residues determination and will be used as official method of analysis.
