The purpose of this study was to investigate snacking behavior in adolescents. We selected one middle school and one high school in 11 school districts in Seoul. The subjects were 1,813 students (904 boys and 909 girls) in 21 schools (11 middle schools and 10 high schools). Subjects reported their snacking behavior: snack frequency, snack type, snack time, with whom to eat snack, place to purchase snack. The subjects were classified into four groups by gender and schooling. The mean snack frequency was 2.8. Girls ate snacks more frequently than boys (p<0.001). More than half of subjects ate 1 to 3 snacks a day. Only 9.3% of them did not eat any snack. Tangerine was highly ranked in snack type. Each subject groups had different snack time (p<0.01) and type of snack (p<0.001). Most snack was consumed alone (46.6%), however they mainly ate fruits and other foods with family. 46.9% of snacks were purchased outside. A typical snack time was ``before dinner`` for most snacks except fruits. Unhealthy foods like soft drinks, cookies, chips, candies, chocolates, ice creams had relatively high proportion in snack consumption with friends. In conclusion, adolescents had different snacking behaviors by their age and gender. These results indicate necessities of multi-dimensional efforts at home, school, media and government level considering adolescents` age and gender for their healthy snacking behavior.

한국의료패널을 통해 본 건강증진 활동과 관련 비용

최슬기 ( Seul Ki Choi ),송은솔 ( Eunsol Song ) 한국보건사회연구원 2021 보건복지포럼 Vol.302 No.-

이 글에서는 한국의료패널 제2기 1차 연도(2019) 자료를 이용하여 성인의 건강증진을 위한 활동(금연, 신체활동) 실천 현황과 이를 위해 지출한 비용을 살펴보았다. 흡연자 중 19.4%가 담배를 끊고자 하루 이상 금연한 적이 있는 금연 시도자였다. 금연 시도자 중 13.7%만이 담배를 끊기 위해 지출한 비용이 있었으며, 연간 총지출 비용은 평균 5만 4천 원이었다. 신체활동을 위해 비용을 지출한 사람은 전체의 21.3%였으며, 연간 총지출 비용은 평균 79만 7천 원이었다. 인구사회학적 특성과 규칙적인 신체활동 실천 여부에 따라 신체활동을 위한 지출 비용에 차이가 있었다. 건강증진행동의 실천율과 이를 실천하기 위한 비용에 대한 이해는 건강증진 사업 및 정책의 기획에 기초 자료로 활용할 수 있다. 건강행동 실천을 위한 비용이 건강행동의 장애물이 되지 않도록 하기 위한 정책적 고려가 필요하다. This paper examines the current status of health promoting behaviors and smoking cessation and physical activity and related costs among adults using data from the Korea Health Panel Study 2019. Among current smokers as of 2019, 19.4% tried to quit smoking at least for a day in 2019. Only 13.7% of those who had tried to quit smoking spent on average 54 thousand won a year on smoking cessation. About 21.3% of the subjects spent money for physical activity, and their annual expenditure was an average of 797 thousand won. The amount spent on physical activity varied according to socio-demographic characteristics and whether or not the physical activity was performed on a regular basis. An understanding of the status of health promoting behaviors and related costs could be used to develop health promotion programs and policies. Policy considerations should be made so that the cost of practicing health behaviors does not become a barrier to health behavior.

장래인구추계의 확실성과 불확실성

최슬기(Seulki Choi) 한국인구학회 2013 한국인구학 Vol.36 No.4

장래인구추계 정보는 미래를 대비함에 있어 활용되는 가장 기본이 되는 자료임에도 불구하고 불확실성에 대한 이해 및 평가는 부족한 경우가 많았다. 이 연구에서는 2011년도 통계청 장래인구추계를 대상으로 추계의 방법 및 결과를 분석함으로써 추계 결과의 불확실성을 평가해보고자 하였다. 연구결과, 인구추계 정보는 추계대상이 되는 미래 연도와 특정 연령대에 따라 불확실성이 크게 달라지는 것으로 나타났다. 우선 출산율 가정이 영향을 미치는 영역은 가까운 미래의 경우에도 불확실성이 상당히 존재했다. 출산율 가정이 영향을 미치지 않는 영역에서는 50년 후인 2060년까지도 남자는 64세, 여자는 74세까지 불확실성이 5% 이내에 불과할 것으로 기대되었다. 즉 장래인구추계는 장래시기 및 연령에 따라 불확실성이 나타나는 정도가 크게 다르고, 일정 연령대에서는 한 세대를 넘어선 미래까지도 신뢰할 수 있는 수치를 제공할 수 있다는 점이 확인되었다. 추계정보의 이용자들은 이처럼 불확실성이 영역에 따라 다름을 고려하여 추계정보를 활용해야 할 것이다. Although the future population projection is the fundamental resource that is commonly used to predict the future, there was lack of understanding regarding its credibility. This research tried to evaluate the credibility of the population projection by analyzing the projection methodology and the results from 2011 future population projection published by Statistics Korea. The results showed that the uncertainty in the population projection altered drastically depending on the estimating year and age. First, in the area where the fertility rate assumption affects, there existed significant uncertainties even in the foreseeable future. In the area where the fertility rate assumption does not affect, the uncertainty was expected to be within 5 percent until 74-year-old for women and 64-year-old for men by 2060. Thus, users of the population projection are advised to consider that the uncertainty differs depending on year and age and to take advantage of this information.

As online education increases, the field of AI in Education (AIEd), where artificial intelligence is used for education, is being actively studied. Knowledge Tracing (KT), which predicts a students knowledge level based on each students learning record, is a basic task in the AIEd field. However, there is a lack of utilization of the dataset and research on the KT model architecture. In this paper, we propose to use a total of 11 features, after trying various features related to the problems, and present a new model based on the self-attention mechanism with new query, key, and values, Self-Attentive Knowledge Tracking Extended (SANTE). In experiments, we confirm that the proposed method with the selected features outperforms the previous KT models in terms of the AUC value.

여성의 생애주기별 식생활 문제

최슬기 ( Seul Ki Choi ) 한국보건사회연구원 2021 보건복지포럼 Vol.299 No.-

이 글에서는 우리나라 여성의 식생활 문제를 살펴보고 여성의 건강한 식생활을 위한 과제를 모색했다. 출생 전의 영양상태를 포함한 전 생애 과정의 식생활은 여성의 건강에 영향을 미치므로 전 생애주기 동안 최적의 영양소를 섭취하기 위한 식생활 관리가 필요하다. 우리나라 여성은 남성에 비해 영양 부족 문제가 더욱 심각하다. 여자 청소년은 신체 이미지 왜곡과 편의식 섭취로 인한 영양 불균형, 청년층 여성은 식생활 관리의 어려움, 성인 여성은 영양 불균형, 노인 여성은 낮은 식사 질이 식생활 문제로 나타났다. 여성의 영양 수준을 향상시키기 위하여 여성의 생애주기에 따른 특징적인 영양 문제를 정책의 대상으로 포함할 것을 제안했다. This paper examines the dietary problems of Korean women and suggests policy actions for women's healthy diets. Dietary intake during the entire life, including nutritional status before birth, affects a woman's health. Thus dietary management is necessary for optimal nutrient intake throughout the life course. Inadequate nutrient intake is more prevalent in Korean women than in men. Korean women's dietary problems are: nutritional imbalance due to body image perception and consumption of convenience foods among female adolescents, difficulties in managing the diet of young women, nutritional imbalance in adult women, and poor dietary quality in elderly women. In order to improve the nutritional status of women, it is suggested to consider women’s life-course nutritional problems as a policy target.

This study was aimed to identify the marine acoustic environment characteristics around Naro-island in summer. Regarding marine environment, water temperature, salinity, and depth of sea and underwater noises were measured and sound speed was calculated from measured element. The depth of sea was measured by using echo sounder set on a research vessel in the study area. Water temperature and salinity were measured by TS-METER (YSI-30, YSI), and sound speed was calculated by Mackenzie (1981) formula. Underwater noise was measured by Hydrophone, and also sediment was measured by sounding lead. The depth of sea was 7~24 m in the study area, also sediment was composed of mud mostly. Water temperature was about 24.1℃, Salinity was about 31.6 psu. And the sound speed of surface layer was about 1531.2 m/s and the bottom layer was 1525.7 m/s. Underwater noise was about 110~135 dB/μPa and it showed lower values as the water depth became deep.
