        이 연구의 목적은 중학교 2학년 물의 순환과 일기의 변화 단원에 대해 STS의 한 방법인NIE 수업자료를 개발하여 학생들에게 처치한 후, NIE가 학업 성취도와 과학 관련 태도에 미치는 효과를 조사하고 학습 방법과 학생들의 학업 능력 수준간의 상호 작용 효과를 알아보고자 하는 것이다. 연구대상은 서울시 동작구에 소재한 여자 중학교 2학년 4개 반을 임의로 선정했고, 학급별로 실험집단과 통제집단에 2학급씩 무작위로 배치하였다. 실험 집단에서는 교사가 관련 개념을 6차시동안 간략하게 강의하고 나머지 7차시동안 개발한 NIE 수업자료로 수업하였고, 통제 집단에서는 전통적인 교과서 위주의 강의식 수업을 하였다. NIE 수업은 Iowa Chautauqua Program에서 활용한 문제로의 초대, 탐색 , 설명, 해결방안의 제시 단계에 따라 진행하였고, STS 학습 지도 전략 중 과학에서 출발하는 접근법으로 프로젝트학습, 토픽학습, 낱말 맞추기 퍼즐 등의 NIE 수업자료를 개발 활용하였다. 학업 성취도 검사 도구는 차시별 수업 목표를 고려하여 연구자가 개발하였고, 과학 관련 태도 검사 도구는 TOSRA의 7가지 영역 중 두 영역, 즉 과학의 사회적 의미와 과학에 대한 흥미적 관심에 해당하는 20문항을 사용하였다. 연구 결과에 의하면, NIE 자료를 활용한 수업이 교과서 위주의 전통적인 수업에 비해 학생들의 학업 성취도를 향상시키는데 효과적이었다(P〈.01). 또한, 과학과 관련된 학생들의 태도 변화에 있어서도 실험집단이 통제집단보다 통계적으로 유의미한 성취도의 우위를 보이는 것으로 나타났다(P〈.01). 학습 방법과 학생들의 성취 수준간의 상호 작용 효과를 알아본 결과 학업 성취도와 과학에 대한 흥미적 관심의 경우에는 주목할 만한 상호 작용 효과는 나타나지 않았으나, 과학의 사회적 의미에 대한 태도에 있어서는 NIE 수업 방법이 전통적인 수업 방법에 비해 하위 집단의 태도를 보다 더 긍정적으로 함양시킨 결과를 유도했다.

        This research was designed to develop a computer program and evaluate the nutritional balances especially the balance of fatty acids, amino acids and antioxidant vitamins for convenience foods. The Korean convenience food, Kimbab purchased from markets was evaluated by using the self-developed computer program. Contents of calories, protein and calcium were lower(1/3˚+1/2) than the recommended levels of Korean adult woman, and the carbohydrate/ protein/ fat(CPF) energy ratio was 70: 13: 17. The mean P/ M/ S ratio was 2.2/ 1.4/ 1 and that of Ω6/ Ω3 fatty acids was 17.9/ 1, which was higher than the desirable ratio of 4~8/ 1. Average essential amino acid balance of market-Kimbab samples was within the desirable range even though the absolute amount of protein was lower than the recommended level. Contents of antioxidant vitamins (A, C &E) were lower than recommended levels. Two kinds of nutritionally adjusted Kimbab menu were established by self-developed computer program. Some of major changes was adding food ingredients such as tuna fish and perilla leaf cooked with sesame oil and soybean oil to increase Ω3 series fatty acids. Some fruits and milk were also added to the menu. The adjusted CPF ratios was 63: 15: 22 and the new values for P/ M/ S and Ω6/ Ω3 fatty acids ratios were 1.0/ 1.2/ 1/0 and 6.1/ 1 respectively. In sensory evaluation of two kinds of adjusted Kimbab, the taste and overall estimation scores were higher than unadjusted Kimbab. The computer program developed in this study might be used as a tool for the evaluation of nutritional balance of other convenience foods and menu planning.

        The purpose of the study was to develop computer-based menu planning program for day-care centers maximizing food preference score among children and satisfying such constraints as expense, nutrients, and season. Children's preference about 142 menu items was surveyed among 382 children of day-care centers. A 16-bit personal computer compatible with IBM-PC/AT was used. The data base files were created by dBASE III Plus, and processing programs were created by using FORTRAN language. Children preferred bread or a la carte menu items to cooked rice in main dish category. Deep fat fried or stir-fried menu items were more preferred than kimchi or cooked vegetables in side dish category. Preference scores for menu items were influenced by cooking methods or main ingredients. The contents of the computerized system show that when the program runs, the user should type inputs of cycle, season, and menu pattern, then the computer lists a series of menu satisfying the criteria of constraints. The user can examine and select a set of menu from the menu lists. Menus are generated seasonally. Menu lists are generated weekly and monthly basis with the contents of menu items, preference scores and price. Nutrient reports are also generated on a weekly and monthly basis with the contents of calories, 12 nutrients and price. Recipes for each menu items are also generated.

        This study was carried out to find out the effect of dietary intake on cognitive function retardation in old age using dietary survey and cognitive function test. The subjects were 332 men of 50-94 years old and their activities of daily living were very similar. The cognitive function was tested by Mini Mental State Examination (MMSE)-K which was translated from MMSE, and the 24-hour recall method was used for dietary survey. Scoring of MMSE-K was a little different from MMSE, that is, in case of no education, one to four points were added to exclude the effect of education which has been considered as a confounder by many researchers. The number of subjects belonging to below 23 of MMSE-K score was increased by increasing age. Even though points were added in case of no education, the ratio of below 23 MMSE-K score group was diminished by increasing education. Therefore, education seems not to be a confounder but a independent variable on cognitive function. Income, past occupation, family type, self-evaluated health status did not play any effect on cognitive function significantly. On the other hand, the correlation between each nutrients and the score of cognitive function test showed that the more consumption of vitamin A and protein, the higher cognitive function score was obtained. In case of iron and Ca, even though it was not statistically significant, there was a tendency of increasing cognitive function score by increasing the intake of those nutrients. This study suggests that micronutrient intakes might be more related to cognitive function than macronutrients.

        양념의 섭취는 고대 에집트 시절부터 시작되어서 현재에까지 인류의 식탁을 지켜 오고 있다. 양념의 용도는 시대에 따라서 다양화되고 있다. 고대에는 양념의 용도는 단순히 음식의 풍미를 돋구기 위해서 사용하였지만, 현대 사회로 올수록, 다양한 음식과 음료수의 맛과 향, 식품저장, 의학적 생리학적인 용도, 및 화장품 및 향수 제조를 위해서 사용한다. 세계적으로 이용되고 있는 양념의 수는 약 70여종에 이르고 있으나, 우리나라 식탁을 오르내리는 상용하는 양념의 수는 10종 내외로 본다. 그러므로 우리나라 음식 향과 맛의 단조로움을 느끼기 때문에 보다 다양한 양념의 개발이 요청된다. 최근 들어와서 고추와 마늘의 생리학적 기능이 재평가되고 있어서, 현대인의 고민인 고혈압과 이와 관련된 순환계 계통의 질병 및 암의 발병 방지 및 치료에도 효과가 있다는 보고가 되고 있다. 위궤양 및 위산분비 비정상인은 자극적인 양념인 고추나 마늘의 섭취를 금지하여 왔으나, 특별히 고추의 섭취가 이러한 상태에 있는 사람들에게 반듯이 위액분비를 자극하지 않는다는 보고도 되어 있다. 양념에 함유된 영양소의 함량으로 미루어 보면 열량 무기질의 일부 및 비타민의 일부 공급원으로 중요하다. 한국인에게 중요한 양념으로 여겨지는 고추와 마늘의 섭취량은 한국 경제가 성장함에 따라 그 섭취량이 증가되는 경향을 나타낸다.

        This treatise deals with chronic state of famine and exploitation of famine relief food in the later half of Chosun Period and especially in relation with socio-economic changes. There with the impact of socio-economic factors on the chronic state of famine and exploitation of famine relief food is studied mainly with a literary approach. The influential factors which lead to the chronic state of famine were not only climatic restrictions such as flood and drought but socio-economic factors such as foreign invasion (Japanease invasion and Ching's invasion), frequent breaking out of revolt and technological development of agriculture (rice transplantation). And disorder of land system and cultivation of cash crops by the richer peasantry, lowering the economic status of the poorer peasantry who were a major constituents of the population, aggravated the famine state. Because the poorer peasantry were under the shortage of food, they had to seek something edible in the fields and mountains. In this process various kinds of famine relief foods were exploited by the poorer peasantry. The majority of famine relief foods were wild vegetables. Consequently the Chronic state of famine was a cause to introduce various edible wild vegetables into Korean food, which influenced modern vegetarian food habits and firmed the Korean's favorite taste to be hot and salty. These wild vegetables couldn't have a marvelous effect on the relief of starved people. Potatoes and sweet potatoes, which were newly introduced foreign crops, were encouraged to be cultivated for famine relief. But these tubers, unable to be staple food, didn't contribute to an increase in population.

        This study was conducted over a 3-year period from 2013 to 2015 in the mid-northern inland, Cheolweon, Korea, to investigate changes in flowering date, daily mean temperature during grain filling, and yield characteristics affected by transplanting date in an early-maturing rice variety, ‘Joun’. Thirty-day-old seedlings were transplanted at four different dates at 15-day interval from May 5 to June 19. Flowering dates were July 16, July 21, July 31, and August 14 when transplanting was performed on May 5, May 20, June 4, and June 19, respectively. Late transplanting resulted in higher daily mean temperature before flowering but late-transplanted rice required fewer days and lower cumulative temperature to reach flowering from transplanting. As transplanting was delayed, daily mean temperature for 40 days after flowering decreased, whereas daily sunshine hours for the same period increased, with a temperature of 24.8°C and sunshine for 5.8 hours being recorded at the transplanting on May 5, and with a temperature of 21.0°C and sunshine for 7.7 hours at the transplanting on June 19. With late transplanting, panicles per square meter significantly decreased, whereas spikelets per panicle showed an increasing trend. Regression analysis showed that maximum head rice yield was attained from the transplanting on May 18, for which the flowering date was July 21, and daily mean temperature for 40 days from that flowering date was 24.6°C. A decrease in head rice yield by 5% and 10% of the maximum was observed for rice transplanted on June 6 and June 15, which resulted in flowering dates of August 2 and August 11, respectively, and the daily mean temperatures for 40 days from flowering were 23.2 and 21.7°C, respectively. Therefore, in mid-northern inland, it is recommended to transplant ‘Joun’ on May 18 to induce flowering on July 21, when grain filling is subjected to a daily mean temperature of 24.6°C during active filling stage.

        The sacrocolpopexy has been the gold standard surgery for POP (pelvic organ prolapse). Though the rates of mesh-related complications after sacrocolpopexy are relatively low, the complications should be considered. This case report describes the clinical cases of removal of mesh eroding following hysterectomy, laparoscopic sacrocolpopexy and posterior vaginal repair. The surgery for complete mesh excision was performed at laparotomy or laparoscopy. Although any complications haven't been yet reported in two cases, careful follow-up management should be needed. Successful sacrocolpopexy without complications requires technically experienced pelvic surgeons, the most suitable surgical methods and the best graft material.

        This study was carried out in 2014 and 2015 to investigate the effect of transplanting density on panicle production and to analyze the relationship of panicle production with yield traits in the mid-maturing quality rice cultivar ‘Haiami’ in the mid-plain area of Korea. Number of tillers per square meter increased by reducing planting distance and increasing seedling number per hill. These effects were maintained until maturity and were reflected in the final number of panicles per square meter, although the effect of planting density decreased as rice growth progressed. However, increased panicle number per square meter following dense planting did not improve head rice yield. Panicle number per square meter was negatively associated with spikelet number per panicle and was not correlated with other yield components or head rice yield. Head rice yield was not correlated with head rice percentage but was closely and positively correlated with milled rice yield. Milled rice yield did not increase with grain filling percentage but increased with spikelet number per square meter. Spikelet number per square meter increased with both spikelet number per panicle and panicle number per square meter, although the former had a greater influence. Therefore, we conclude that head rice yield of the ‘Haiami’ cultivar grown in the mid-plain area of Korea is not improved with an increased panicle number following high planting density but it could be improved with high milled rice yield by increasing spikelet number per unit area.
