The first priority of sedation for incorporative children in pediatric dentistry is a safety. Therefore, evidence-based practices in health care are needed for preventing medical accidents. In accordance with the rise of the evidence based medicine, the interest in Evidence-Based Dentistry is increasing in the field of dentistry. However, systematic research about Evidence-Based sedation in Korea has rarely been done. As such, the purpose of this systematic review is to critically analyze the available scientific literature regarding dental sedation and to seek the next developmental strategies about evidence based pediatric dental sedation. A broad search of the 5 databases of the systematic reviews manual of the National Evidence-based Healthcare Collaborating Agency in Korea were referenced: 1) Core search database- KMbase, KISS; 2) Academic information and portal; 3) the National Assembly Library; 4) DBpia, and 5) RISS. Of a total 470 themes limited to the search term of "dental sedation", in accordance with the PRISMA statement for reporting systematic reviews of health sciences interventions, a literature selection process, which includes the removal of overlapping down the flow chart, was performed. Of the remaining 31 articles, two authors read through articles independently and added or removed articles using the exclusion criteria. Finally, twenty published papers of acceptable quality were identified and reviewed. This systemic review of Korean pediatric dental sedation practices for the last twenty-five years was based on the objective criteria defined in the GRADE process and identified consistent evidence. The results were evidence of moderate quality. Therefore, more systemically well-designed clinical studies are needed about the safe use of a sedative medicines (drugs).

Despite to the reality that the outbreaks from flood poisoning in Korea have been continuously increasing in the last two decades, it was very much neglected even in the public health field in Korea. Food poisoning outbreaks resulted in many cases not only in the damage of health but also in the death of many lives. However, this problem can be effectively solved by effects through health education activities, but not solely by the legal measures. This study was carried out to provide information that can be used in planning health education programs and proposing new rules to prevent any possible outbreaks from flood poisoning. The main problems contributing to flood poisoning outbreaks in an institutional setting or school catering and at home were reviewed and analyzed through the epidemiological investigations and articles related to flood poisoning in the last a decade (1991 ∼ 2000). Accordingly, the data presented in this study are sufficient to show and prove the significant trends in food poisoning accidents in Korea. The major findings investigated in this study are as follows. The frequency of food poisoning accidents as well as the number of victims have continuously increased in Korea. The number of victims per food poisoning accident is also increased from 20 persons in 1990 to 69.8 persons in 2000. Therefore, we should realize that the group poisoning outbreaks occur more frequently and the size of group poisoning accidents is getting larger. Among four seasons, the food poisoning accidents occurred more frequently in the summer (May ∼September) until 1997, However, after 1997, the food poisoning accidents occurred evenly in three seasons except the winter. The most important bacteria that cause food poisoning in Korea were Salmonella spp., Vibrio spp. and Staphylococcus aureus. They occupied 85∼90% of the rates of accidents and the number of victims.

Objective : The purpose of this study was to investigate the quality of life and it's related factors in caregivers of attention deficit hyperactivity disorder patients. Methods : The subjects were 38 attention deficit hyperactivity disorder patients' caregivers(mean age : $37.5{\pm}6.5$, 38 women). Patients were diagnosed with DSM-IV-TR ADHD criteria. Korean version of WHOQOL-BREF(World Health Organization Quality of Life assessment instrument Abbreviated Version) was used for assessment. Results : 1) No significant differences were found in the score of WHOQOL-BREF, overall QOL, physical health domain, psychological domain, social relationships domain and environmental domain between caregiver and control group. 2) The score of Activity of daily living facet$(3.0{\pm}0.7\;vs.\;3.6{\pm}0.7)(p=0.008)$ and self-esteem facet $(2.8{\pm}0.7\;vs.\;3.3{\pm}0.7)(p=0.049)$ were significantly decreased in caregivers of ADHD. 3) Total score of WHOQOL-BREF(r=0.437, p=0.007) and physical health domain(r=0.370, p=0.024) were correlated with caregiver's educational age. 4) In the psychological domain, the score of self-esteem facet(r=-0.337, p=0.039) and thinking, learning, memory & concentration facet(r=-.341, p=0.036) were decreased with caregiver's age. 5) The score of environmental domain were significantly increased with caregiver's educational age (r=0.482, p=0.003), but decreased with patient's age(r=0.328, p=0.044). Conclusion : Although the quality of life in caregivers of ADHD patient had not significantly decreased than control, the quality of lift were positively correlated with educational age of caregives, and negatively correlated with chronological age of caregivers and children. Above results suggest that physicians should consider integrated approaches for caregiver's subjective quality of life in the management of ADHD.

To determine the contents of sodium and potassium in side dishes, 92 samples from 22 different kinds of side dishes that can be classified into 3 groups were collected in Seoul area and analysed using ICP-OES. The highest sodium content was detected in pepper doenjang muchim, while potassium content was the highest in kong jorim. When comparing the content of sodium and potassium in 3 groups, namely namul, muchim, and jorim, the sodium content of namul group was significantly different from those of jorim and muchim (p-value < 0.05). Sodium intake per serving size was the highest in parae muchim among the samples as estimated to 20.2% of WHO recommendation that is 2,000 mg/day. The amount of sodium by simultaneously intake of soybean sprouts namul, anchovy jorim and parae muchim per one serving size was estimated to 1,000 mg. The potassim/sodium ratios of spinach namul and kong jorim were 1.70 and 0.81, respectively, while that of bracken namul was very low as about 0.1. Food-borne pathogens were not detected out of 92 side dishes.

This study is aimed to provide the primary data about safety of cosmetics products using indirect preference of korean cosmetics customer and numerical comparison of applied area. For this study, we collected 9,879 cosmetics products which were inspected in cosmetics research team from January, 2010 to December, 2012. The domestic cosmetics was 645 cases (6.5%) and Imported cosmetics was 9,234 cases (93.5%). As manufacturing country, the France has 4,342 cases (44.0%) and the next ranking were like those, Germany 1,637 cases (16.6%), U.S.A 1,476 cases (14.9%), Republic of Korea 645 cases (6.5%), Italy 557 cases (5.6%), and etc 1,222 cases (12.4%). By the year, the cases of test cosmetics have decreased from 3,784 cases (2010), 3,394 cases (2011) to 2,701 cases (2012), the relative ratio of common cosmetics part was drop in but the other group (functional cosmetics and hair dye related products) was increased. The largest market share product was Skin care 5,470 cases (55.4%) and the next order was like those, Make up 1,908 cases (19.3%), Hand & Foot 1,026 cases (10.4%), Hair Care 616 cases (6.2%), Bath 361 cases (3.7%), and etc 498 cases (5.0%). In domestic cosmetics, the greatest proportion was Skin care and the others were Hair Care > Makeup > Hand & Foot > Bath, but the proportion was evidently changed in imported cosmetics, Skin care > Makeup > Hand & Foot > Hair Care > Bath. It is necessary to set the priority of the international quality standards to identify trends from domestic consumers directly or indirectly. Compare the ratio of category and human application parts from domestic and imported cosmetics, we utilize leverage as the basis for future-oriented cosmetic safety.

The prevalence rate for chronic diseases such as obesity, diabetes, hypertension etc. caused by the increment of national income and the change of food life according to the globalization in Korea have been increased. Especially excess sodium intake may contribute to the development of hypertension, increasing cardiovascular disease risk. The objective of this study was to investigate sodium intake of nursery school meals in Gyeonggi-Do, and to construct database for lesser sodium intake policy. Survey consisted of 601 sample intakes of sodium in summer and in winter. A food weighed record method was used for measuring food intakes. Average intakes of ten children per nursery school were measured. The sodium contents of meals were analyzed by ICP-OES (inductively coupled plasma-optical emission spectrometer) after acid digestion by microwave. The sodium contents on food groups showed that sources (693 mg/100 g), grilled foods (689 mg/100 g) and kimchies (643 mg/100 g) had respectively higher sodium contents and the average sodium intake per meal was $582\pm204$ mg. The sodium contents of soups & hot soups and kimchies had 37.5% and 15.8% of total sodium intakes per meal, respectively. Sodium intakes per meal in summer and winter showed 572.3 mg and 592.3 mg, respectively. Regional ranking of sodium intakes showed the ascending order of apartment (514.3 mg/meal), rural region (540.5 mg/meal), multiplex house (635.9 mg/meal) and industrial complex (696.4 mg/ meal). A habit of excessive sodium intakes in childhood will threaten their health when they grow up to be adults; thus lesser intake of sodium per meal is needed for children in nursery school.

In order to study the occurrence of symptoms of musculoskeletal disorders of radio-technologists employed at metropolitan general hospitals and the factors that influence such occurrence, standardized questionnaire by NIOSH that was modified and supplemented to be suitable for conditions in Korea was used. Answers collected from 143 radio-technologists in two weeks from June 13, 2007 were analyzed and the results are as follows. Factor that influence symptoms of musculoskeletal disorders by area were analyzed through multiple logistic regression analysis and the results found that in the neck area, risk increased as the burdening work category 2(Korea ministry of labor)(OR=3.94) and burdening work category 9(Korea ministry of labor)(OR=4.72) increased. In the shoulder region, risk increased as burdening work category 2(Korea ministry of labor)(OR=5.36), burdening work category 7(Korea ministry of labor)(OR=3.90), and burdening work category 9 (Korea ministry of labor)(OR=5.76) increased. In the arm/hand/wrist regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=6.91), and burdening work category 9 (Korea ministry of labor)(OR=3.76) increased. In the lower back region, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.06), and burdening work category 8 (Korea ministry of labor)(OR=8.14) increased. In the leg/knees/foot regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.63), and burdening work category 9 (Korea ministry of labor)(OR=2.96) increased. Conclusively, in factors that influence musculoskeletal disorder symptoms in radio-technologists, influence of subjective health conditions, total work experience, experience in current division, and burdening work category 2, 7, 8, and 9 (Korea ministry of labor) were most significant. Therefore, for preventive management, in addition to ergonomic and educational intervention for correcting improper posture during work, efforts for break time adjustment and stress reduction is needed, and encouragement and support for regular exercise is needed.

Vibrio is a genus of Gram-negative, curved, halophilic, and non-spore-forming bacteria. Some of the Vibrio species, such as V. cholerae and V. parahaemolyticus, often contaminate seafood products and occasionally cause human diseases when the seafood products are ingested. A total of 24 Vibrio strains were isolated from shrimp samples on Thiosulphate citrate bile salt sucrose (TCBS) media in this study. All of the 24 isolates were confirmed to belong to the genus Vibrio by using 16S rRNA gene sequence analyses. Vitek 2 system and species-specific polymerase chain reaction (PCR) methods were used to further identify a total of 29 Vibrio strains at the species level, including the 24 shrimp Vibrio isolates and five Vibrio reference strains. The specificities of the two methods to identify Vibrio strains at the species level were compared in this study. The species-specific PCR method was designed to detect five different Vibrio species, such as Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio alginolyticus, and Vibrio mimicus. From the 24 Vibrio shrimp isolates, the Vitek 2 system method could identify 15 (62.5%) strains as Vibrio species and 7 (29.2%) strains as non-Vibrio species, but could not identify the rest 2 (8.3%) strains. But species-specific PCR method could identify 16 (66.7%) strains as Vibrio species and could not identify the rest 8 (33.3%) strains. Among the 24 Vibrio shrimp strains, these two methods could unanimously identify 7 (7/24, 29.2%) strains (2 V. parahaemolyticus, 4 V. alginolyticus, and 1 V. mimicus). Considering that such different identification results were obtained using the two different methods in this study, identification method for Vibrio species must be carefully chosen.

Safety and health related information for the proper use and handing of pesticides is usually printed on the surface of the pesticide products in the form of texts. But, the guidelines or standards for the appropriate presentation of the texts for the pesticide products are most vague or not practical. Thus, this study aimed to provide the preliminary guidelines for the text sizes based on the legibility experiments. To achieve the objective legibility evaluation experiments were conducted to test the effects of different near vision (0.6, ${\geq}0.8$), gender, font type(thick gothic-type and fine gothic-type), thickness of font(plain and bold), and number of syllables(2 and 3 syllables) in the same age group of 20s. The results showed that legibility was different according to the visual acuity (p<0.05), and no other main effects showed statistically significant effects. The 'maximum illegible size' to read at least one word correctly in all the text conditions was 2 pt when the near vision was ${\geq}0.8$, and 2 pt or 3 pt when the near vision was 0.6. The 'minimum legible size' for 100% correct answer was 9 pt for the near vision of 0.6, and 5.3 pt for ${\geq}0.8$, respectively. Mean character size does not read any discomfort in 0.6 was 15.5 pt in both male and female but male was mean 8.5 pt, female was 10 pt in ${\geq}0.8$. Considering these experimental results, it was recommended that the 16 pt or larger characters should be used the important information such as 'Pesticides' or toxicity, and the minimum character size was 9 pt for the less important information.

Salmonella spp. are one of major pathogens for zoonosis in worldwide, and can replicate within host cells and generally cause enterocolitis and foodborne poisoning which represents a considerable public health burden. The present study was designated to investigate the safty for host cells, antibacterial effects of Saururus chinensis Baill water extract (SCWE) on pure culture and infection with Salmonella enterica serovar Typhimurium (S. typhimurium) in murine derived macrophage RAW 264.7 cells. The different treatment of SCWE concentration (1, 10 or $100{\mu}g/ml$) did not show any cytotoxic effect to RAW 264.7 cells for 24 h incubation. In determination of antibacterial activity of SCWE against S. typhimurium, bacterial viability was markedly decreased compared to SCWE-untreated control. In RAW 264.7 cells, SCWE significantly induced morphological change (p<0.05). In infection assay of S. typhimurium in RAW 264.7 cells pretreated with $100{\mu}g/ml$ of SCWE, which are non-cytotoxic concentration, bacterial uptake ability of macrophage was increased corresponding with morphological change, whereas bacterial survival rates within macrophage was markedly reduced comparing to that of SCWE-untreated control. Furthermore, nitric oxide (NO) production in SCWE-treated cells was slightly decreased until 24 h post infection. Taken together, these findings demonstrated that SCWE have the antibacterial activity for S. typhimurium and the protective effects against S. typhimurium infection through activating murine macrophage independent on NO, suggesting that SCWE were beneficial on the disease caused by intracellularly replicating pathogens as a safe alternatives of conventional chemotherapies.
