This study was conducted to examine the status of food consumption and nutrition intake of young adults according to food security using data from the Korea National Health and Nutrition Examination Survey (KNHANES) (2008~2018). A total of 10,655 young adults aged 19~34 years participated in the study. The subjects in the moderately/severely food insecure group consumed less fruits, vegetables, meat, nuts and seeds than those in food secure/mildly food insecure group after adjusting for confounding factors. The moderately/severely food insecure group significantly decreased mean adequacy ratio (MAR) and nutrient adequacy ratio (NAR) for protein, vitamin A, riboflavin, niacin, vitamin C, calcium, phosphorus and iron compared to the food secure/ mildly food insecure group. The percentages of the participants consuming a daily diet with carbohydrate, protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, phosphorus and iron less than the estimated average requirement (EAR) increased in the moderately/severely food insecure group compared with the food secure group. This study suggested that the nutrition intake of young adults was related to food security status. These findings can be used as basic data for developing nutritional policies for young adults.
There is little information on the nutrient intake according to the city size and small town in Korean elderly. This study analyzed the nutritional consumption of older people in metropolitan, middle and small cities, and rural areas according to four income levels. The recent data from the 2016~2018 Korean National Health and Nutrition Survey, Centers for Disease Control and Prevention were used. The final analysis included 4,325 individuals (Male: 1,856, Female: 2,469) over 65 years old. Multivariable regression with a complex sample design was conducted to compare the nutrient intake among the groups. In a comparison within regions, the nutrition status of the elderly in small towns was more vulnerable than metropolitan and middle & small cities. The energy intakes were similar between the groups. The carbohydrate intake of middle & small cities was significantly higher than the other regions. The intake of other nutrients in metropolitan and middle & small cities appeared to be higher than in rural areas. The number of nutrients with statistical significance between low and high-income levels were 19 in metropolitan, 11 in middle & small cities, and 5 in rural areas. Each contribution of carbohydrate, fat, and protein to the total energy intake was lower in the low-income level than the high-income level in metropolitan and middle & small cities. On the other hand, in rural areas, only the contribution of protein to energy intake was lower in the low-income level than the high-income level. Cities with higher levels of urbanization had more severe nutritional inequality in relation to the income level. There was also nutritional inequality present in rural areas but it was to a lesser extent. Moreover, the generally low level of nutrient intake was problematic in rural areas. These findings could be used as fundamental evidence for developing community nutritional policies for the elderly.
This study examined how teaching and learning activities in primary English textbooks include the components of creativity and character building. Three third and fourth grade level textbooks based on the 2015 revised curriculum were analyzed in order to find the proportions of the components of creativity and character building, and the types of learning activities that embody those components were analyzed by examining the teachers’ guides. The analysis revealed that all of the textbooks examined included diverse components that were intented to increase creativity, among which components stimulating divergent thinking and originality were a high proportion, while convergent thinking and dispositional aspects appeared less frequently. Among character building components, care-forgiveness and responsibility were two of the more popular components, while honesty and moral judgment were few and far between. From these findings, this study suggests that the components of creativity and character building should be more evenly distributed across textbook activities since they should be of equal importance in education.
Purpose: This study investigated the dietary patterns associated with Korean food and the level of proper eating habits according to recognition of the Kimchi cooking method, and aimed to suggest the necessity of dietary education of traditional foods such as Kimchi. Methods: Based on the results of the national dietary survey conducted in 2014 by Ministry of Agriculture, Food and Rural Affairs of Korea, a total of 1200 subjects were classified into two groups, one that knew how to make Kimchi (53.8%) and another that did not (46.2%). Results: The group that knew how to make Kimchi (FG) showed significantly higher scores in knowledge of how to cook most types of Korean foods and traditional fermented foods than the other group (NG). Moreover, FG showed significantly higher scores in regularity in meals and a higher frequency of Korean foods such as rice, Kimchi, and grilled or stewed food, while it showed significantly lower scores in dietary risk factors than NG. In addition, FG showed significantly higher scores in dietary education interest and number of meals with family during the week than NG. Finally, FG had significantly higher scores in the degrees of practice of all eight items related to proper eating habits. Conclusion: Since recognition of Kimchi cooking has a great influence on maintenance of dietary life, dietary education to improve the cooking ability of traditional foods should be further strengthened.
Ecological restoration is an eco-technology, which heals the nature damaged by human activity by imitating organization and function of the integrate nature and thereby provide an inhabitable space for diverse organisms. Such an ecological restoration has to be carried out by applying restoration plan prepared based on the results of diagnostic evaluation discussed in the diversified respects. This study aims to prepare an ecological restoration plan of the damaged forest ecosystem in Mt. Moodeung National Park. To arrive at the goal, first of all, we diagnosed quality of forest landscape established in Mt. Moodeung National Park based on natural (topography, climate, and distribution of vegetation) and artificial (land use, linear landscape element) factors. In addition, we evaluated the integrity of each zone divided by linear landscape element quantitatively based on geometric property and land use intensity. As the result of analysis, topography of Mt. Moodeung National Park tended to be depended on weathering property of parent rock and vegetation zones were divided to three vegetation zones. Based on land use pattern, deciduous broad-leaved forest, evergreen needle-leaved forest, and mixed forest occupied about 90% of Mt. Moodeung National Park. Mean score of forest landscape quality was shown in 69.86±11.41. As a result, forest landscape elements in Mt. Moodeung National Park were influenced greatly by human activity and the degree was depended on topographic condition. This study suggested the synthetic restoration plan to improve ecological quality of Mt. Moodeung National Park based on the results of diagnostic evaluation.
본 연구는 국립공원 탐방객 개인의 라이프스타일에 따른 만족도 차이가 존재하는지에 대한 파악을 위해 수행되었다. 북한산국립공원 탐방객 대상의 자기기입식 설문조사를 통해 라이프스타일을 분류하고, 집단별 만족도 차이를 검증하였다. 탐방객 라이프스타일은 탐색적 요인분석 결과 5개 요인으로 구분되었으며, 이들 5개 요인을 이용하여 군집분석을 실시하여 4개의 군집이 적합군집으로 분류되었다. 라이프스타일에 따른 군집별 만족도 차이분석 결과, 각 군집별 만족도는 통계적으 로 유의한 차이가 있는 것으로 나타났다. 군집유형 중에는 적극적인 성향집단에서 만족도가 가장 높게 나타났으며, 다음으 로 사회적 성향집단, 개인적 성향집단, 소극적 성향집단의 순으로 만족도가 높게 나타났다. 이러한 탐방객 사회문화적 변수로서 라이프스타일 유형별 만족도 차이는 국립공원에서의 탐방객 관련 시설 및 프로그램 운영에 있어 전체 탐방객 대상의 통합적 접근 보다는 탐방객 유형별 세분화 접근의 필요성을 시사한다.
질감, 모양, 색채 등 내용기반 영상검색(CBIR)의 기능을 이용하여 한국의 지리산 국립공원과 영국의 케이른고럼스 국립공원의 자연 경관에 있어서의 차이를 판별하는데 본 연구의 목적이 있다. 먼저 각 국립공원의 자연경관을 디지털 사진영상으로 촬영한 후, 전형적인 경관사진을 선별하였다. 사진영상의 저단계 기능(Low-level function)이 계량화되어 수직적으로 회전된 다섯 개의 요인으로 축약되었다. 이 중 유의한 차이를 보이지 않은 물 관련 요인이 제외된 나머지 네 개의 요인에 근거한 판별선이 케이른고럼스 경관과 지리산 경관 사이에서 도출되어, 판별함수가 두 그룹을 유의하게 분할하였다(2(4)=61.433; p〈0.001). 고유치 2.417과 월크스 람다 0.293에 의하여 전체 변이가 두 그룹의 판별함수 평균의 차이에서 대부분 산출되었음을 확인하였다. 또한, 네 개의 독립변수가 종속변수 전체 분산의 70.7%를 설명하는 것으로 추정되었다. 경관에 대하여 가장 큰 효과를 나타내는 변수는 원거리관련 변수(r=1.073)이며, 다음으로 근거리관련 변수(r=0.896)였으며, 전체적으로 90.7%가 타당하게 분류되었다. 이는 케이른고럼스 국립공원과 지리산 국립공원 자연경관 사이에서 사진영상의 근거리 요인뿐만 아니라, 원거리 요인이 보다 경관 차이에 유의한 판별력을 보이는 것으로 해석되므로, 국립공원의 경관정체성과 관련한 원거리 스카이라인의 시각적 중요성을 보여주는 것이라 하겠다.
The 7th national curriculum takes a strong stance for a student-centered curriculum as well as operating and management flexibility at the school level. This study explored the procedures of and the status on implementation of the 7th national English curriculum at the primary level. It examined the processes taken by the local boards of education in due course of facilitating the schools with the school level curriculum implementation, and the schools and teachers for the actual curriculum implementation. To achieve the goal of the study, it was conducted by questionnaires for teacher and supervisors, classroom observation, and teacher interviews. Results were interpreted by the core aspects of the 7th national curriculum: curriculum reconstruction, student-centeredness, and specialization of the curriculum. Three major elements were found in the process of curriculum modification: firstly, the local boards of education was not enough to support so that the schools developed and implemented the school-based curricula secondly, teachers did not exert autonomy in interpreting and applying curriculum to their classrooms, and finally, there was a high demand for teachers and experts with potential in the schools as well as in the board of education. For the successful settlement of curriculum, continuous efforts are needed to involve teachers in the process of curriculum implementation.
Daily intakes of 14 preservatives were evaluated by using their maximum permitted levels(MPL) and national food disappearance data in 1998. The estimated daily intake (EDI) of each preservatives were compared with corresponding acceptable daily intakes (ADIs). EDIs of dehydroacetic acid, sodium dehydroacetate, p-hydrobenzoic acid ester, propionic acid, sodium propionate and calcium propionate were leas than 2% of ADI and judged to be safe. However, EDI of sorbic acid and potassium sorbate were 76.61 mg/person/day and it reached 5% of its ADI. EDI of benzoic acid and sodium benzoate were 85.65 mg/person/day and it reached 31% of its ADI. The highest intake of benzoic acid came from carbonated drink.
This study evaluated the contamination levels of inland pollution sources flowing into Taeanhaean National Park. The nutritional status of influents was assessed by analyzing water quality and trophic status index (TRIX) at 52 stations, and the contamination levels of sediments were evaluated by analyzing eutrophication cleanup index (CIET) and heavy metals at 36 stations. The results of the TRIX analysis showed that 26 of the 52 stations had influents with a TRIX value of 6-10 (poor water quality/very high trophic level), indicating atrocious water quality and high eutrophication levels. The results of the CIET analysis showed that 4 out of the 36 stations were highly contaminated with organic matter. Analysis of heavy metals showed that the copper (Cu) and zinc (Zn) levels exceeded the threshold effects level (TEL) and probable effects levels (PEL) at several stations. In addition, the arsenic (As) level exceeded the threshold effects level at one station, and the levels of the other heavy metals (Cd, Cr6+, Ni, Pb, and Hg) were lower. Most inland pollution sources have been identified as small-scale, but long-term and continuous exposure can negatively affect the marine ecosystem; therefore, it necessary to prepare inland pollution source management standards and measures suitable for the characteristics of the coastal area.
