        한국 지역사회영양의 현황과 전망

        채범석,한정호 대한지역사회영양학회 1996 대한지역사회영양학회지 Vol.1 No.1

        The nutritional status is strictly related with flood production, flood processing, and distribution along with habits, education and technological achievement, adapted and adjusted to socio-economic conditions. All these factors are independently affecting the nutritional status of populations. In addition to the above mentioned factors launch of it is useful to consider two points ; unification of the South and the North Korea and WTO. The present study gives and overview of basic knowledge about nutritional status of Korean by using availab1e data in relation to nutrition. The basic characteristics of Korean diet with proportions high in carbohydrate and low in fat, have been relatively constant for the past two decades. The average daily flood intake in terms of weight of flood per person is relatively constant throughout the years. Although the proportion of animal food intake tends to increase recently, the Korean diet is still insufficient in meat, eggs, milk, and fish. Moreover because milk has not been accustomed flood with the general population and not much used in traditional flood preparation in Korea, milk consumption was especially low in comparison with western countries. The total energy intake was relatively constant throughout the years from 1969 to 1993. However, changes in the composition have occurred in the past two decades. The amount and proportions of fat have been s1ightly increasing while the total amount of carbohydrate has been decreasing. The nutrition preblems of Korea have changed over the past severa1 decades. The general adequacy of protein and energy existing after Korean War(1950) was resolved now. Since then the average diet appears to be nearly desirable in terms of rapid rates of growth during childhood and attainment of progressively stature and body weight at maturity. The dietary habits of some young people in these days seem to be taking a more western style diets. This trends if established by habit may lead to a marked change in the traditional diet and health. I think Korean nutritional experiences have potential values for tole other countries in Asia and in western countries. Korean diet illustrates a high level of nutritional status and health attainable will a largely vegetable diet : high in complex carbohydrates, and dietary fibre, and low in tat, and reasonable amount of total protein. This is significant for developing and developed countries that must select specific goals fir adequate nutrition for the people. Compared to the western countries, Koreas different incidence of coronary heart disease and malignancy demonstrates the significance of environment and probably the prominent role of diet in the development of these diseases. The changes occurring in the Korean diet of fir the unusual opportunity to assess the effect of diet upon chronic degenerative disease. In the future, the Korean diet might be continue to change significantly These changes are being influenced by socioeconomic factors that have been emerging and growing stronger since mid-l980 and that probably continue to be potent. The expanded purchasing power of the consumer results in increased discretionary purchases. In the case of foodstuffs, the consumer demands appear to be directed toward items of higher protein content, which, being primarily animal products, are inevitably accompanied by an increased consumption of fat. The continued availability of these more expensive flood items depends upon the balance of foreign trade favouring their importation and domestic production. A regression of foreign trade could result in a decreased supply for the consumer, whereas continued growth of trade iou]d provide freedom for increasing availability to the consumer. In this latter situation the exact choice of foodstuffs is depending upon comsumer tastes and the pressures that may influence it.

        오픈 소스 기반의 정찰 및 탐색용 드론 프로그램 개발

        채범석,김정환 대한임베디드공학회 2022 대한임베디드공학회논문지 Vol.17 No.1

        With the recent increase in the development of military drones, they are adopted and used as the combat system of battalion level or higher. However, it is difficult to use drones that can be used in battles below the platoon level due to the current conditions for the formation of units in the Korean military. In this paper, therefore, we developed a program drones equipped with a thermal imaging camera and LiDAR sensor for reconnaissance and exploration that can be applied in battles below the platoon level. Using these drones, we studied the possibility and feasibility of drones for small-scale combats that can find hidden enemies, search for an appropriate detour through image processing and conduct reconnaissance and search for battlefields, hiding and cover-up through image processing. In addition to the purpose of using the proposed drone to search for an enemies lying in ambush in the battlefield, it can be used as a function to check the optimal movement path when a combat unit is moving, or as a function to check the optimal place for cover-up or hiding. In particular, it is possible to check another route other than the route recommended by the program because the features of the terrain can be checked from various viewpoints through 3D modeling. We verified the possiblity of flying by designing and assembling in a form of adding LiDAR and thermal imaging camera module to a drone assembled based on racing drone parts, which are open source hardware, and developed autonomous flight and search functions which can be used even by non-professional drone operators based on open source software, and then installed them to verify their feasibility.

        시계열 예측 모델을 이용한 식물생장 환경에서의 LED 수명예측 방안

        채범석,김영진,김형진 한국지능시스템학회 2023 한국지능시스템학회논문지 Vol.33 No.2

        As interest in the smart farming market increases, various academic approaches arebeing attempted to predict the lifespan of LEDs that supply light for plant growth,but the experimental method is complicated and the time and cost are quiteexpensive, so it is difficult to apply to smart farm environment that requiresreal-time management. This paper shows the illuminance and PPFD(PhotosyntheticPhoton Flux Density) data necessary for plant growth using a spectrophotometerand uses the ARIMA(Auto-regressive Integrated Moving Average) model, which isone of the time series prediction approaches, to collect the data accumulated after acertain period of time in the future. By estimating the data of the LED, we proposea method to predict the lifespan of the LEDs with less time and cost. Finally, basedon the data calculated as an approximate equation representing the temporal changeof light output in the LED degradation model, the predicted data is compared andanalyzed using the ARIMA model. 스마트팜 시장의 관심이 증가함에 따라 식물생장에 필요한 빛을 공급하는 LED의 수명예측을 위해 다양한 학문적 접근이 시도되고 있으나 실험 방법이 복잡하고 소요 시간과 비용이상당히 높아 실시간 관리가 필요한 스마트팜 환경에 적용하기 어려운 문제를 가지고 있다. 본 논문은 분광조도계를 이용하여 식물생장에 필요한 조도와 광합성유효량 광량자속밀도 데이터를 수집하고 일정기간 이후 누적된 데이터를 시계열 예측 접근 방법 하나인 ARIMA(자동회귀누적이동평균) 모델을 활용하여 미래 시점의 데이터를 예상함으로써 적은 시간과 비용으로 LED의 수명을 예측할 수 있는 방안을 제시한다. 마지막으로, LED 열화모델에서 광출력의 시간변화를 나타내는 근사식으로 산출한 데이터를 기반으로 ARIMA 모델을 활용하여 예측된 데이터를 비교 분석한다.
