This study explored how high-school students perceived the work and life balance of biologists. In addition, this study examined the differences in this perception according to students’ gender and academic year. A total of 400 high-school students participated in this study. In the data collection, three open-ended questions about biologist’s enjoyment, concerns, and the weekend life in daily life were used. The collected response data were qualitatively analyzed and inductively categorized. All data were divided into the context of work and the context of personal life. Chi-square was conducted to examine differences in students’ perception in terms of gender and academic year. As a result of categorizing the responses, six themes in enjoyment, eight themes in concerns, and four themes of weekend life were revealed. Most of students perceived biologists’ usual enjoyments and concerns in daily life within the work context: nearly half of the students described the biologists’ weekends within the work context. It was found that female students tended to perceive biologists’ enjoyment and concerns in a work context more than male students. In sum, many students perceived biologists as workaholics who have difficulties with work-life balance. Based on these results, the workaholic image could be an obstacle to career exploration and decisions about a career as a biologist. Thus, this study suggested that career education regarding biology for future generations should consider the aspect of work-life balance. In particular, career educational programs should introduce the daily life of a biologist whose life both at work and personally is happy and satisfactory; this is necessary for students’ positive career exploration and aspiration toward a career as a biologist.

This research examined the influence of status and regulatory focus on go-around decision making. The result showed that there was no difference between captains and first offers on the go-around decision making about various landing situations. But there was significant relationships between regulatory focus and go-around decision making. Prevention focus was positively related with uncertain situation, and runway situation. Promotion focus has positive relationshipwith deficiency situation but has negartive relationshipwith runway situation.

This study explored the overconfidence bias and hard-easy effects of students biological concept levels and self-monitoring accuracy. To this end, 361 high school first and second grade students participated in the study. As a consequence of this study, there were differences between genders or years in the four types of knowledge-confidence and significant differences between genders in specificity. As a result of clustering model analysis, hard-easy effects were found in a large number of students, and there were many cases in which the tendency to overconfidence was noticeable. Based on these findings, it was suggested that students should be educated to recognize and reduce hard-easy effects and overconfidence bias through different educational strategy between student groups.

본 연구에서는 제 6기 국민건강영양조사 자료를 이용하여 우리나라 노년을 대상으로 아침식사 결식에 따른 영양소 섭취 및 식습관 행태를 조사하였다. 연구대상자는 만 65세 이상 3,966명을 분석하였으며, 아침식사섭취군 및 아침식사결식군으로 나누었다. 1일 탄수화물 및 비타민 B₁, 칼슘, 나트륨, 철분 섭취량은 아침식사섭취군이 높은 반면에, 1일 지방 섭취량 및 1일 콜레스테롤 섭취량은 아침식사결식군이 높았다. 영양소 적정 섭취 비율(NAR)은 비타민A를 제외한 8개 영양소에서 아침식사섭취군이 아침식사결식군에 비해 유의적으로 높게 나타났다. 추후 노년기의 건강한 생활습관 개선을 위해 아침 결식 이유를 고려한 다양한 연구가 진행되어야 한다. I investigated the nutrient intake and dietary habits based on the breakfast skipping in elderly Koreans using the 6th Korea National Health and Nutrition Examination Survey. The analysis included 3,966 elderly participants aged over 65 years and the subjects were divided into two groups. The breakfast eaters consumed significantly higher levels of carbohydrate, vitamin B1, calcium, sodium and iron whereas the breakfast skippers consumed more levels of fat and cholesterol. In addition, the nutrient adequacy ratio(NAR) of the breakfast eaters were significantly higher levels of 8 nutrients except for vitamin A than the breakfast skippers. Further investigation into the reasons for skipping breakfast may be useful for promoting healthy lifestyles of elderly.

This paper is foundation paper about national wind map verification using remote sensing, based on analysis of comparison between numerical simulation and remote sensing on complex coastal area of regional coast. As a result analysis using NCAR/NCEP, wind direction of numerical simulation and remote sensing is same. but, wind direction of some case is showed different. Such as this result, if it would be used without verification of analyzed data, present ability of occurring lots of error, and it will be verified based on using survey data or atmospheric data.

본 연구에서는 삼육식품이 당뇨병 조절을 위해 개발한 두유를 당뇨병 환자의 동의하에 섭취시켰으며, 삼육케어(당뇨관리식)의 효능을 입증하기 위한 임상시험을 실시하였다. 당뇨관리식 섭취 전과 후의 BMI는 18.88±1.16 kg/㎡, 20.74±1.06 kg/㎡였다. 당뇨관리식 섭취 후에 식사할 때, 음식에 소금이나 간장을 더 넣지 않는다는 비율과 식사는 매일 세끼를 규칙적으로 한다는 비율은 증가하였다. 당뇨관리식 섭취 후에 에너지 섭취량, 단백질, 지방, 비타민 B6, 비타민 B12, 엽산, 칼슘, 철, 셀레늄, 인 및 식이섬유 섭취가 증가하였다. 당뇨관리식 두유를 섭취시키기 전과 후의 혈중 콜레스테롤 수치는 144.00±8.02 mg/dL에서 142.46±7.49 mg/dL로 감소하는 경향을 보였으며, LDL-콜레스테롤 수치는 10.30±1.72 mg/dL에서 8.11±0.74 mg/dL로 유의하게 감소하였다(P<0.05). 따라서 당뇨관리식 두유 섭취는 당뇨환자의 영양상태 개선 및 LDL-콜레스테롤 수치 개선에 도움을 주는 것으로 사료되며, 앞으로 지속적인 임상 연구가 진행되어야 할 것으로 판단된다. This study evaluate the health improvement efficacy of Sahmyook Care (diabetic control diet) vegetable soymilk intake in elderly diabetic women. This randomized clinical trial was conducted by enrolling 18 elderly diabetic women aged 65 to 80 years, after obtaining their informed consent. Subjects were randomly assigned to consume a diet containing soy milk developed by Sahmyook Food for diabetes management for 4 weeks. The average BMI of the subjects before and after diabetic control diet intake were 18.88±1.16 kg/㎡ and 20.74±1.06 kg/㎡, respectively. Eating habits after consuming the diabetes control diet, showed an increase in the ratio of not adding salt or soy sauce to food and regularly eating three meals a day. Energy intake, protein, fat, vitamin B6, vitamin B12, folic acid, calcium, iron, selenium, phosphorus, and dietary fiber intakes were also increased after partaking in the diabetes control diet (P<0.05). The level of LDL-cholesterol in blood before and after intake of soymilk for diabetes management showed a significant decrease, from 210.30±1.72 mg/dL to 108.11±0.74 mg/dL (P<0.05). Therefore, the consumption of soymilk in a diabetes-controlled diet is considered helpful in improving the nutritional status and LDL-cholesterol levels in diabetic patients.
정량적인 해양환경패턴 분석을 위한 이변량 공간연관성 적용
황효정 ( Hyo Jung Hwang ),최현우 ( Hyun Woo Choi ),김태림 ( Tea Rim Kim ) 한국지리정보학회 2008 한국지리정보학회지 Vol.11 No.1
마산만의 해양 수질과 영양염에 대한 정량적인 이변량 공간패턴 분석을 수행하기 위하여 비공간 상관성 측정 방법으로 Pearson`s r, 공간적 연관성 측정 방법으로 Moran`s I 및 이 두 지수를 통합한 L 지수를 각각 적용하였다. L 지수에 내포된 비공간 상관성과 공간 연관성의 특성을 파악하기 위해 Pearson`s r와 Moran`s I 지수를 각각 3가지 유형으로 구분한 후, 이들을 조합하여 9가지 유형으로 정의하였다. 또한 L 지수의 사분위수를 이용하여 9가지 유형에 대해 중복되지 않는 L 지수의 범위를 도출한 결과 9가지 유형이 5개의 그룹으로 분류되었다. 이러한 L 지수를 마산만 해양환경패턴에 적용한 결과에 의하면 이변량의 해양수질과 영양염이 2월과 7월에는 공간적인 연관성과는 무관하게 비공간적으로 상관성이 없는 패턴을 보였지만, 5월과 11월에는 정적 또는 부적 상관성이 있으면서 공간적으로는 군집된 패턴을 보였다. L 지수로 이변량의 비공간 상관성과 공간적 연관성을 해석하기 위한 지침을 제시한 본 연구의 결과는 향후 정량적인 지수를 이용한 해양환경패턴 분석에 도움을 줄 것으로 기대한다. The quantitative bivariate spatial pattern analysis was applied for the water quality and nutrients data of Masan Bay, and for this analysis Pearson`s r as aspatial correlation measurement, Moran`s I as spatial association measurement and L index as integration of aspatial and spatial measurement methods were used. To understand the aspatial and spatial characteristics implicated in L index, Pearson`s r as well as Moran`s I were classified into 3 types respectively, and Pearson`s r and Moran`s I were combined with 9 types, and also quantile of L index value was used for each of those 9 types. Finally, these types were defined as 5 groups having not overlapped L index range. According to the application result of L index groups, bivariate water quality and nutrients showed no aspatial correlation regardless of spatial association in February and July, but they showed aspatial correlation having clustered spatial pattern in May and November. The result of this study providing the guideline for the interpretation of aspatial correlation and spatial association using L index is expected to be helpful for the marine environment pattern analysis using quantitative index for further study.
