The purpose of this study was to analyze the status of environment-related teaching in elementary and secondary schools. A questionnaire survey was conducted for the study. Items in the questionnaire were developed based on the theory of environmental education and integrated education. The questionnaire was responded to 501 elementary school teachers, 273 middle school teachers, and 210 high school teachers in the city of Seoul and Kyunggi Province. The survey analysis revealed that elementary and secondary school teachers recognized 'environmental action skills' as the most important objective for school environmental education. Contrary to the teachers' expectations, it was found that there is insufficient teaching and learning materials for teaching in the domain of 'environmental action skills' and they could not confidently teach the skills in environment-related classes. For professional development of teachers in integrated environmental education, pre- and in-service programs will be developed systematically in a workshop to give teachers an opportunity to analyze teaching materials, design instruction plan, perform class trial, and evaluate the class situation for feedback. The results of this study can serve as a basic reference for improvement of environment-related subject education.

The study was a descriptive cross-sectional survey which investigated the reading preferences of secondary school students in Nigeria during the lockdown occasioned by COVID-19 pandemic. A hundred secondary school students in Ile- Ife and Ilesa in Osun State, Nigeria were the study respondents. Close ended self-administered questionnaire was used to obtain data. Of the one hundred questionnaire which were applied to the study respondents, ninety-three were retrieved. Data obtained were analyzed using simple frequencies and percentages. The study established that majority of respondents were not pressured to read but read for pleasure. Preference for a wide range of fiction and non-fiction books which was read for purposes ranging from academic, social, relaxation and information was indicated by respondents. Availability of reading materials determined reading preference of majority of respondents as many could not afford to access electronic books whether free or not. The researchers recommended that different types of reading materials that suit the reading preferences and meet the diverse purpose of reading should be provided for the secondary school students during lockdown to improve their reading habits. Public libraries should function during this lock down period within the guidelines of the appropriate health authorities, while school libraries should be equipped to offer virtual services during the lockdown and the students should be exposed to e-books for their reading pleasure.

조사비용과 시간과 같은 현실적인 제약하에서 관측단위 (observation unit)의 집합인 집락(cluster)율 추출하는 집락추출법은 대부분의 대형조사(large scale survey) 에서 흔히 사용된다. 특별히 집락내의 관측단위가 매우 유사한 경우, 집락 내의 모든 관측치를 조사하는 대신 일부를 추출하여 조사하는 이단계 집락 추출법이 선호된다. 이단계 집락추출법의 적용시 집락인 1차추출단위 (Primary Sampling Unit; PSU)와 관측단위인 2차추출단위(Secondary Sampling Unit; SSU)의 표본수 결정은 주어진 비용과 표본으로부터 계산되어지는 통계량의 정도에 의존한다. 본 연구에서는 기존의 1차추출단위의 크기가 동일하다는 가정하에서 유도된 최적 PSU와 SSU 표본크기 산출과정을 일반화하여 1차추출단위의 크기가 같지 않을 경우의 최적 표본크기를 유도하고 그 결과를 제 4차 퇴원환자조사를 위한 표본추출 방안에 적용하여 기존방법과 비교하였으며 이를 바탕으로 제 7차 퇴원환자조사를 위한 표본크기를 제안하였다.

For estimating a net removal of carbon dioxides from a forest carbon offset project, it is necessary to consider secondary emissions occurred from the use of machineries or vehicles. According to the forest carbon standard in Korea, a default rate (5%) could be applied for estimating secondary emissions of small projects, which provide annual net removals less than or equal to $600tCO_2$, while secondary emissions should be estimated for larger projects with field survey. In this study, we intended to develop a methodology for estimating the secondary emission of a forest carbon project. For this purpose, we analyzed the working process and the carbon emissions of the forest management activities for major tree species in Korea. Based on the developed methodology, we estimated the secondary carbon emission of a reforestation project. The result showed that the secondary carbon emission of a reforestation project was estimated between 0.42% and 1.19 % compared to net removals, that is to say that the current default rate in the forest carbon standard could give an overestimated secondary emission.

Purpose: Lactose intolerance (LI) is perceived to be frequent in Asia and has been reported to have considerable impact on dietary intake, nutritional status and the quality of life. We aimed to gather information from healthcare professionals on the perceived incidence, diagnosis and management of LI in 1 to 5 year old children in Southeast Asia. Methods: An anonymous electronic survey was sent randomly among healthcare professionals registered in the database of the pediatric societies in Thailand, Indonesia, and Singapore between June and October 2016. Results: In total, 259 health care professionals responded of which 45.5% (n=118) were from Thailand, 37.4% (n=97) from Indonesia and 16.9% (n=44) from Singapore. Of the participants who responded (n=248), primary LI prevalence among children 1 to 3 years of age was estimated to be less than 5% by 56.8%. However, about 18.9% (n=47) answered they did not know/unsure. Regarding secondary LI, 61.6% of respondents (n=153) estimated the prevalence to be less than 15%. But again, 10.8% (n=27) answered they did not know or unsure. Rotavirus gastroenteritis was ranked as the top cause for secondary LI. There was considerable heterogeneity in the diagnostic methods used. The majority of respondents (75%) recommended lactose-free milk to manage primary and secondary LI. Conclusion: More education/training of pediatricians on this topic and further epidemiological studies using a more systematic approach are required.

The primary and secondary survey was designed to identify all of a patient's injuries and prioritize their management. However 15 to 22.3% of patient with missed injuries had clinically significant missed injuries. To reduce missed injury, special attention should be focused on patients with severe anatomical injury or obtunded. Victims of blunt trauma commonly had multiple system involvement. Some reports indicate that inexperience, breakdown of estalished protocol, clinical error, and restriction of imaging studies may be responsible for presence of missed injury. The best way of reducing clinical significant of missed injuries was repeated clinical assessment. Here we report a case of severe blunt hepatic injury patient and pericardial injury that was missed in primary and secondary survey. After damage control surgery of hepatic injury, she remained hemodynamically unstable. Further investigation found cardiac tamponade during intensive care. This was managed by pericardial window operation through previous abdominal incision and abdominal wound closure was performed.

The purpose of this study is to conceptualize the definition of school readiness specific to the context of the Republic of Korea. The school readiness test can be used as basic data to enable early childhood educational institutes to determine the general readiness of preschoolers and provide support to fit individual characteristics. For this purpose, six stages of the school readiness development process were considered, that is, draft development, primary preliminary survey, primary expert verification, secondary expert verification, secondary preliminary survey, and main survey. In the main survey, tests were conducted using the school readiness final draft targeting 344 preschoolers living in Seoul and Gyeonggi-do. The item discrimination power analysis and factor analysis for the examination area and question area were also conducted. Consequently, a test tool was developed on the basic of the results obtained, consisting of 129 items in the five areas of knowledge, function, adaptation, tendency, and attitude. The knowledge area was divided into general, linguistic, and mathematical knowledge, and the function area into fine motor function, basic living ability, expressive function, and gross motor function. The adaptation area was classified into adaptation activity, separation anxiety, maladaptive behavior, and environment adaptation; the tendency area into learning tendency; others understanding, and individual tendency, and the attitude area into rule compliance and life habits.
