  • This study tried to analyze the factors affecting consumers' vehicle selection for the spread of eco-friendly vehicles. We used the energy census data for this purpose, and although the energy census collects useful information from a large number of samples, it has been limitedly used to create simple statistics in many cases. Based on 2,771 transport sector microdata from the 2017 Energy Census, we collected vehicle price, fuel efficiency, and number of vehicle models, which are alternative characteristic variables that change according to consumers' choice, and converted and analyzed data to enable conjoint analysis. The analysis results in two-folds. First, it was confirmed that the official fuel efficiency of a vehicle and the fuel cost, which is affected by changes in the relative price of each fuel, are important variables in selecting an eco-friendly vehicle. In order to achieve the goal of spread of eco-friendly vehicles, it is necessary to develop technologies to improve fuel efficiency and set appropriate electric rates for charging electric vehicles. Second, an increase in the number of vehicle models through the expansion of the eco-friendly car industry and market also affects consumers' choice of eco-friendly vehicles, so efforts to expand the supply of eco-friendly vehicles will be an important factor. In addition, it is also significant that this study showed that the use of the energy census can be diversified by deriving meaningful policy implications using the results of the energy census periodically conducted in the country without a separate survey.

  • The energy band method for NaI spectrum calculates only the exposure rate due to natural radiation because it calculates exposure rate using energy spectrum of $1300{\sim}3000keV$. However, the total energy method includes in its calculation the exposure rate due to man-made radiation because it uses the energy spectrum of $150{\sim}3400keV$. Therefore, the resulting difference of extracting the exposure rate calculated by the energy band method from the exposure rate calculated by the total energy method is apparently the exposure rate due to man-made radiation. In this study, we measured the NaI spectrum during the period of significant changes of the exposure rate in the area without a man-made radiation. As the results, we found the exposure rates calculated by those two methods are equal within the statistical variation of ${\pm}0.3{\mu}R\;h^{-1}$. Consequently, if the difference between the exposure rates calculated by the two methods exists, it may be due to the man-made radiation exposure rate.

  • 21세기의 에너지 문제는 핵융합과 태양에너지 이외에는 다른 해결방법이 없고 환경오염문제 등을 생각하면 오히려 태양에너지 이용쪽이 실현가능성이 크다는 견지에서 서독연구기술성은 베를린 공과대학, AEG테레프겐회사, 도르니에 ㆍ시스팀회사에 인공위성에 의한 태양에너지 이용의 가능성에 대하여 조사연구를 위촉하였다. 그 결과에 대하여 AEG테레프겐회사의 하르트밤박사는 한 강연에서 2020년경에는 태양에너지 위성에 의하여 세계에너지 부족이 해소될 것이라고 다음과 같이 말하고 있다.

  • 인류의 생존위기 의식이 날로 고조돼 가고 있다.에너지 및 인구폭발에 기인한 식량난과 대기 해양 오염에 따른 공해로 진통을 겪고 있다. 특히 석유석탄 등 에너지 자원의 매장량은 불원한 미래에 고갈될 것으로 예견하고 있다. 이의 타개를 위해 세계각국은 새로운 에너지원 개발을 서두르고 있다. 과학기술처는 소계곡을 개발,영구순환에너지원을 얻고져 소수력발전에너지원 입지조사를 실시했다. 개발계획이 실현될 때 적어도 100만kw의 전력과 새로운 소로를 관개수리사업에 이용할 수 있으며 공수재난을 막을수 있게 된다는 것 전국에 산재한 소계곡이 우리의 손으로 하루속히 개발되어 부족한 에너지 확보와 국토보존에 크게 이용되기를 갈망하며 그 내용을 샆펴보기로 한다.

  • Purpose: This study evaluated the accuracy of the 24-hour diet recall method for estimating energy intakes in elderly women using the doubly labeled water (DLW) method. Methods: The subjects were 23 elderly women with a mean age of 70.3 ± 3.3 years and body mass index (BMI) of 23.9 ± 2.8 kg/㎡. The total energy expenditure (TEEDLW) was determined by using the DLW and used to validate the 24-hour diet recall method. The total energy intake (TEI) was calculated from the 24-hour diet recall method for three days. Results: TEI (1,489.6 ± 211.1 kcal/day) was significantly lower than TEEDLW (2,023.5 ± 234.9 kcal/day) and was largely under-reported by -533.9 ± 228.0 kcal/day (-25.9%). The accurate prediction rate of elderly women in this study was 8.7%. The Bland-Altman plot, which was used to evaluate the TEI and the TEEDLW, showed that the agreement between them was negatively skewed, ranging from -980.8 kcal/day to -86.9 kcal/day. Conclusion: This study showed that the energy intake of elderly women was underreported. Strategies to increase the accuracy of the 24-hour diet recall methods in the elderly women should be studied through analysis of factors that affect underreporting rate. Further studies will be needed to assess the validity of the 24-hour diet recall method in other population groups.
