The study analyzed 343 government-authorized and officially approved textbooks of the Seventh Curriculum's specialized subjects in high school from March to September, 2007. The textbooks were categorized into the area of agriculture, industry, commerce, household and business, science, foreign languages and physical exercise and analyzed in terms of the target and content areas of marine education. And the findings were as follows: First, among the textbooks in the seven groups serving as the focus of this study, 19.8% have oceanic-related information but pages including ocean contents occupy only 0.8%. Consequently ocean-related contents are scarcely included. The ocean-related contents are necessary to be treated goals. Second, the goals of school oceanic education are focused in vocational subjects. In order of commonality, information & knowledge are most frequent, then functionality, followed by activity & participation. There was no education provided focusing on value & attitude. Given that school oceanic educations were selected for promoting the importance of the ocean and highlighting the problems of the ocean, the lack of information & knowledge is of concern. The goals of oceanic education should be augmented to actively and positively participate in the solutions of the problems with knowledge, ocean-friendly value & attitude, and increased activity & participation. Third, the contents of school oceanic education commonly focuses on the relationships of oceans and humans, oceans and ecology, and artificial oceanic environments and facilities. Less common but still introduced are ocean resources, sea pollution, sea preservation and measures. Yet, in contrast there is a lack of education in the ethics of sea preservation.

Purpose: As of July 31, there were 14,336 confirmed cases of COVID-19 in South Korea, including 301 deaths. Since the daily confirmed number of cases hit 909 on February 29, the spread of the disease had gradually decreased due to the active implementation of preventive control interventions, and the daily confirmed number had finally recorded a single digit on April 19. Since May, however, the disease has re-emerged and retaining after June. In order to eradicate the disease, it is necessary to suggest suitable forward preventive strategies by predicting future infectivity of the disease based on the cases so far. Therefore, in this study, we aim to evaluate the transmission potential of the disease in early phases by estimating basic reproduction number and assess the preventive control measures through effective reproduction number. Methods: We used publicly available cases and deaths data regarding COVID-19 in South Korea as of July 31. Using ensemble model integrated stochastic linear birth model and deterministic linear growth model, the basic reproduction number and the effective reproduction number were estimated. Results: Estimated basic reproduction number is 3.1 (95% CI: 3.0-3.2). Effective reproduction number was the highest with 7 on February 15, decreased as of April 20. Since then, the value is gradually increased to more than unity. Conclusion: Preventive policy such as wearing a mask and physical distancing campaigns in the early phase of the outbreak was fairly implemented. However, the infection potential increased due to weakening government policy on May 6. Our results suggest that it seems necessary to implement a stronger policy than the current level.

Purpose: To analyze the data of patients who suffered trauma in a cultivator accident and visited the trauma center in rural Gyeongbuk Province. Methods: We retrospectively reviewed the medical records and Korean Trauma Data Bank data of 120 patients who suffered cultivator-related traumas and visited the rural regional trauma center in Gyeongbuk Province from January to December 2015. Results: The age of the patients ranged from 35 to 96 years (mean, 70 years). Ninety-one (75.8%) patients were men, and twenty-nine (24.2%) were women. Most of the patients were in their 70s (46 men [50.5%] and 13 women [44.8%]). In total, 113 patients (94.1%) arrived at the regional trauma center by ground transport and 7 (5.9%) arrived by air transport. Ninety-eight patients (81.7%) were transported to the regional trauma center directly from the scene of the accident, and twenty-two (18.3%) were transferred from another medical institute. The mean time from the accident to arrival at the emergency department was 139 minutes, and only 46 patients (38.3%) arrived within 1 hour. Twelve (10.0%) patients died, including two deaths on arrival and two post- cardiopulmonary resuscitation deaths in the emergency department. All deaths were of male cultivator operators. The causes of death were shock (hypovolemic, traumatic, or septic), subdural hematoma (open), hemothorax, rhabdomyolysis, and pneumonia. Conclusions: As the government - led regional trauma center project is on process, it would be clinically important to summarize the initial outcome of cultivator injuries, which are characteristically found more in regional trauma centers in the rural area, and have high mortality. Based on this study, in the future, it will be necessary to follow up and analyze more number of patients and to construct accurate database about trauma cases related to cultivator in Gyeongbuk region.

Korea is one of the countries with a large veterinary antibiotics market, although antimicrobial resistance in bacteria is becoming a serious issue in many countries. The Korean government started to take interest in estimating the effects of livestock manure on rivers and agricultural soils and in monitoring of heavy metals, organic pollutants and antibiotics in the ambient water and soil. In this paper, pre-treatment methods to separate the selected antibiotics from solid samples were reviewed. It is essential to select an efficient and appropriate procedure for pre-treatment due to the high proportion of proteins and organics in biosolid samples. Pre-treatment consists of extraction followed by clean-up. Initially, homogenized samples were extracted by sonication, mechanical agitation or pressurized liquid extraction with methanol/acetonitrile/water mixture under acidic/basic conditions depending on the compound. However, aminoglycosides and colistin were extracted with 5% trichloroacetic acid and HCl, respectively. Since the ${\beta}-lactams$ are easily decomposed in acidic and basic conditions, they were extracted in neutral pH. Filtration with a membrane (pore size, $0.2{\mu}m$) or solid phase extraction with HLB and methanol, as eluents, was normally applied for the clean-up. At least, three different pre-treatment procedures should be adopted to screen all the selected antibiotics in solid samples.

Purpose: This study was aimed to identify the status of utilization of healthcare services and self-care behaviors, knowledge level and influencing choice factors of non-prescription drugs (OTCs) on consumers since sales of OTCs at the outside of pharmacy in Korea, and to confirm the changes in perception of consumers for OTCs policy through check of perception level for current OTCs policy. Methods: Data was collected from April 2014 to May 2014 from questionnaires by 418 adults who are in university located in Seoul or live in Seoul Metropolitan area but not health science major and healthcare providers. Results: The female gender was 56.6% and University students were 73.9%. The ratio by age was as follows: below 25 (60.9%), 26-30 (18.2%), 30-40s (14.9%) and 50-60s (6.0%). The knowledge level of OTCs for use of medicine, dose and side effects was generally low and especially they knew little how to deal with side effects after taking OTCs on sale at the outside of pharmacy, even though over one year has passed since the policy. The proportion of those who thought the current OTCs policy has problems regarding safety issues since the policy was very high and it was also high that the study group thought there are problems with the current way to sale OTCs and educate employees. Conclusion: After selling OTCs at the outside of pharmacy, the consumers still lacked knowledge of OTCs and did not get correct information properly. Especially, they had little information about the way to deal with side effects after taking OTCs. Public policy should be based on the health of the people and the public health is a national health priority. When all these things are taken into consideration, the government has to strengthen the OTCs policy and provide a safer environment with the accurate drug information for people than developing OTCs policy in the future.

Purpose: Smoking has more injurious impacts on teenagers compare to adults in that they are in the growing stage with incomplete cells, tissues, and organs. Usually smoking among adolescent group is closely related to illegal drug uses. Also, smoking in the youth drives them to ill health in adulthood, so that they will pay future national health cost. The purpose of this study was to evaluate the impacts of school life and home surroundings on adolescent's smoking. The result of this study will be utilized to promote antismoking moods in schools and homes. Method: Samples of the study are all middle and high school students in one community. The surveys were conducted from May 13th to October 29th, 2004 using the questionnaire developed by researchers. T-test, ANOVA test, Chi-square test and logistic regression analysis were performed to identify the differences of teenagers' school life and their home surroundings between smoking and non-smoking groups using SPSS 12.0 English version. Results: The findings were that there was a significant difference between smoking groups and non-smoking groups related to school life and home surroundings. Smokers were less satisfied with their school work and had poor school record and poor relationships with their friends. Smokers had more smoking parents and don't set along with and less satisfied with their parents. Conclusion: In conclusion, the teenagers' school lives and home surroundings have impacts on adolescent's smoking. Therefore, it is very important to include the factors related to the teenagers' school lives and home surroundings in the smoking prohibition program in order to promote antismoking.

In recent, occupational diseases in harmful working places become a social issue. It is the well-known fact that a respiration in polluted working places exert a serious effect on health of workers. Accordingly, the cutting off contaminants air originally is the best way to improve working environments. In these cases, ventilation systems should be essentially installed to dilute or exhaust the contaminated indoor air. In this study, we investigated the characteristics of ventilation system of the noxious gas in working indoor places with natural ventilation by using COMET. The numerical simulations were carried out the natural ventilation with two phase(air, dust). For turbulent flow, Reynolds stresses were closed by the standard $\kappa$-$\varepsilon$ model. The results are as follows ; 1) In the natural exhaust in the working place, the flows of the central region have a more rapid velocity vector than the right and left one. 2) Numerical results show that the distribution of contaminants concentration have greater influence on convection than the case of diffusion by government of velocity vectors. 3) To observe the velocity variation with distance, three location of distance are considered. As results, it shows that the velocity are 0.075(m/s) at y=5(m), 10(m) and mean concentration are raised 10.6% at y=5(m), 10(m). 4) We have presented the useful data for the adequate counterplan in the harmful working places by carrying out the various investigation of the natural ventilation.

Objectives : The records of 447 pesticide poisoning deaths from the National Forensic Service (NFS) headquarters located in Seoul of Korea from 2005 to 2009 were retrospectively reviewed. Methods : The data of each case were analyzed by using the SPSS program. Results : The mean age was $57.8{\pm}14.8$ years and the range was 16-92 years. The numbers of deaths of males and females were 301 and 134, respectively. The largest number of cases occurred in people aged 50-59 years (n=92, 20.6%) followed by the age groups 40-49 years (n=91, 20.4%), 60-69 years (n=88, 19.7%), and 70-79 years (n=75, 16.8%). The total number of deaths among other age groups (10-19, 20-29, 30-39, 80-89, and 90-99 years) was 73, representing only 16.3%. Of all pesticide poisoning deaths, 96.2% were due to suicide, and 28.4% of the total number who died received medical treatment. The mostfrequent site of ingestion was the person's own residence (n=279, 62.4%). The most common classes of pesticide were bipyridylium herbicide (paraquat, 31.1%), organophosphate insecticide (21.7%), and carbamate insecticide (15.4%). The major pesticides having a high proportion of fatalities were paraquat (31.1%), methomyl (11.4%), glyphosate (9.1%), dichlorvos (5.6%), phosphamidon (4.6%), and methidathion (4.0%). Conclusions : This study showed that poisoning deaths due to pesticides are one of the major public health problems in Korea. Enforcement of regulations and safety education to prevent pesticide poisoning should be carried out by the government.

This research involved a survey on the dietary patterns of children and adolescents living in group homes, to find out their wrong eating habits and to devise measures for correcting their problems. The BMIs of the subject children and adolescents in group homes were measured, and the result showed that although many of them appeared to have normal weights, about 42.2% were actually underweight. Most of them had meals regularly, three times a day at fixed times. However, half of them frequently skipped breakfast because of the lack of time in the morning. In addition, more than half of them had the habit of having imbalanced diets, especially with low vegetable intake. The score for their satisfaction toward meals at group homes were highest (3.97) with the taste of food, while it was relatively lower (3.61) with the variety of food than with the other items. The average score for their snack intake was 3.47, showing that the majority of them had the habit of eating snacks, while the largest portion (26.0%) of them preferred bread and cookies. According to the result of the analysis on their food intake, overall calorie intake was about 82~96% of estimated energy requirements, while that of the male subjects aged 12 or older was about 82% of the standard energy requirements. Their overall intake of calcium and potassium was lower than recommended nutrition intake, but sodium intake was higher than 3 times recommended intake. Especially, in addition to calcium and potassium, the male subjects aged 15 or older showed low intake of dietary fiber, iron, zinc, riboflavin, niacin, vitamin C and folate also; whereas the female subjects aged 15 or older showed low intake of iron, zinc, riboflavin and folate also. Taken together, it was concluded that government level of dietary life-related support and management would be necessary for the healthy growth and development of children and adolescents in group homes.

This study was carried out to evaluate meal management behavior of housewives and to improve their behavior by determining what problems exist. The survey was conducted using a questionnaire in Jinju from October to November in 1999. It was shown that 29.1% of housewives didn't plan food budget, whereas only 5.6% of them did. The reasons for not planning food budget were mostly due to not forming a habit(38.8%), irregularity of prices(19.9%) or irregularity of income(13.8%). The characters of planning food budget and the reasons for not planning were not affected by age, education, monthly income, family size or monthly flood cost. Only 17.8% of meal managers recorded their housekeeping in detail and 47.4% of them wrote only the important things. Recording housekeeping records was affected by age and education. It was found that most meal managers(90.8%) didn't set menu planning and they didn't fuel the need for menu planning. The frequency of food shopping was every two days(36.2%), twice a week(20.9%) or randomly(27.4%), and the places for food shopping were supermarket(49.0%) and traditional market(41.3%). Both were affected by education or age. The quality of food was the main reason(54.6%) far the selection of food shopping place. Important consideration for selection of food and meals was preference of family(47.4%) and this character was affected by education. It was shown that the score of nutrition knowledge was 7.36, and it was affected by education. The results of this study suggest that the government, educators and scientists in nutrition make efforts to develop various levels of practical education programs for meal management and nutrition depending on age, education and community using mass media.
