세기(counting)와 같은 일상 경험에서 비롯되는 수와 연산에 관한 비형식적 지식은 이후의 학교 교육에 영향을 주며, 문제에 기술된 행위나 관계 유형에 따른 여러 가지 문장제를 해결할 때 문제해결 전략에도 영향을 준다. 이에 본 연구에서는 덧셈과 뺄셈의 문장제를 15가지 유형으로 구분하여 교과서에 제시된 문장제를 분석하였다. 또한 115명의 초등학교 2학년 학생을 대상으로 각각의 문장제에 대한 풀이 결과를 분석하였다. 교과서를 분석한 결과, 덧셈의 경우에 전체적으로 합병 상황의 문장제가 첨가 상황의 문장제보다 많았다. 또한 뺄셈의 경우에 구잔 상황의 문장제가 구차 상황이나 등화 상황의 문장제보다 많았다. 학생들의 문장제 풀이 결과를 분석한 결과, 덧셈 상황에서는 첨가 상황의 문제와 합병 상황의 문제에서 정답률의 차이가 거의 없는 것으로 나타났다. 그리고 뺄셈 상황에서는 구잔 상황의 문제에서 다른 두 상황의 문제보다 정답률이 높게 나타났다.

The purpose of this study was to examine the change of couple relationship factors predicting marital satisfaction and divorce intention over time tv comparing the couples' first year with their present year of marriage. The couple relationship factors consisted of affection, ambivalence, affectional expression, the expression of negativity. The study subjects 355 married women having preschool children aged 7 years old and elementary school students in the 6th grade. Data were analyzed by SPSSWIN with the method of MANOVA. The results of this study showed that couples in happy groups without divorce intention became less affectionate and demonstrated less affectional expression, and more ambivalence and expression of negativity over time. However, the amount of change was not as large as that of the unhappy groups. The findings of this research indicated that the decline of affection and affectional expression and the increase of ambivalence and expression of negativity were probably, as normative, a natural consequence of the transition from the first year of marriage to a more mature relationship. Therefore, the change over time was not important. However, the amount and aspects of change were the main points which researchers and practitioners should pal attention to in the future.

This study is designed to positively transform a teacher's emotional state whilst teaching their classes and be able to create happier lessons for preschool children. To do this, a teacher needs to reflect upon current problems and take steps to deal with them. The data for this study was collected from participatory observation and in-depth interviews, making use of photos, a reflective teacher's journal and interview records from Mar. 28, 2011 through Oct. 7, 2011. The problems identified were, (1) teacher centered classes, (2) a daily routine filled with large group activities, (3) disruptive students, and (4) repetitiveness. The routes to greater classroom "happiness" are (1) rearranging seats, (2) "story sharing activities" in small groups, (3) making a separate "story sharing activity" area, (4) using small groups instead of large groups, (5) changing the daily routine. The role of the teacher in finding greater "happiness" are (1) meaningful, 'real observation', (2) discovering genuine change from small points, (3) power sharing, and (4) growing and developing with children.

This study was performed to analyse some rick ffactors for chronic degenerative diseases of the Korean dict. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classfied to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. The dietary risks for chronic degenerative disease such as food sources of fat consumption, high cholesterol intake, low dietary fiber intake, and low calcium intake and high protein intake were analyzed. Younger subjects had more animal fat proportion than older subjects did. HS and CS had the least fat proportion from fishes and shellfishes. Each mean cholesterol intake of PC, EC, HS, and CS was over 300mg/day, and HS load the highest level of 415mg/day. Cholesterol density of the diet of PC was the highest of 175mg/1000kcal and the level decreased when the age increased. The subjects consuming cholesterol over 100 mg/1000kca1 were about 70% of PC and HS. More than 20% of PC, EC, and HS consumed calcium under 75% of RDA with protein consumption over 125% of RDA. Dietary fiber intakes were 18g for HS, CS, 30-49 years, and 50 ∼ 69 years, 14g for EC and over 70 years, and 12g for PC. Ninety percent of PC and EC, 80% of HS and CS, and 70% of tole subjccts over 30years consumed dietary fiber under the level of 10g/1000kca1. The major food sources of dietary fiber were vegetables and grains. From these results, children and adolescents had ricks for chronic degenerative diseases on all the analyzed items. The results of this study would provide the basic information for development of dietary interventions to improve diet find health.

Objectives: An outbreak of shigellosis occurred among students and staff of S primary and middle school, Seongju-gun, in 2003. This investigation was carried out to institute an effective counterplan, and study the infection source and transmission of the shigellosis. Methods: The authors conducted a questionnaire survey among 235 students and staff from S preschool, primary and middle school relating to the ingestion of school lunch and the manifestation of symptoms. Also, the author investigated the drinking water, feeding facility and reconstructed cooking process of the food presumed to be the cause of the shigellosis. The diarrhea cases were defined as confirmed cases and those cases who had had diarrhea more than one time, accompanied with symptoms such as fever, vomiting and tenesmus. Results: From rectal swabs 20 people, between June 28 and July 4, 2003, were confirmed with shigellosis. The diarrhea attack rate was 40.0%. Those who had ingested tomatoes and cubed radish kimchi had significantly higher diarrhea attack rates (p<0.05), with the relative risk of tomatoes being 2.69 (95% CI: 0.98-7.42). The major cause of shigellosis was presumed to be from contaminated tomatoes due to cooking with rubber gloves containing holes. Conclusion: The cooks in charge of school lunches must make doubly sure to not only attend to their sanitation, but also to manage the table wear and items used in providing school lunches. The health care authority should introduce higher-leveled criteria for health care among cooks, so that they cannot cook when the have a case of any infectious disease.

This study was performed to develop an index assessing the overall diet quality for Korean. The study subjects consisted of preschool children (PC), elementary school children (EC), high school students (HS), college students (CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 people. Newly developed Korean diet quality index (KDQI) was an index assessing the overall diet quality from the view point of balance. KDQI was based on the nutritional problems of Koreans, dietary risk factors for chronic degenerative diseases, 5 major food groups, and dietary guidelines. The ten components of KDQI were vegetables, fruits, dairy products, dietary variety score, calcium intake, iron intake, energy intake, fat intake, and cholesterol intake. The full score of each component was 10 points and the score of KDQI was calculated by summing the scores of the 10 components. When the KDQI was applied to this study subjects, the distribution of subjects KDQI scores was similar to normal distribution. Mean score of KDQI was 56.0 and the range of the mean by age was from 45.7 for the subjects over 70 years old to 60.7 for the elementary school children. The components which composed the lowest three means were dairy intake, fruit intake, Ca intake in most age groups. Mean score of DVS was one of the highest three but not for the subjects over 50 years old. After subjects with KDQI score over 70 were classified to higher poop and those with KDQI score under 40, to lower group, nutritional characteristics were compared. Energy contributions of carbohydrate, proteins, and fit, percentages of RDA for major nutrients, and dietary diversity scores were more adequate in the higher poop than in the lower group. The lower poop had more risks for chronic degenerative diseases. According to the results, KDQI was valid index to assess the overall diet quality and it could be used to detect risk group for malnutrition and chronic degenerative diseases.

It is necessary to compare the dietary characteristics among different age groups because different nutritional problems require different dietary applications. This study was performed to identify the nutritional characteristics of Korean diet among different age groups. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Energy intake was as much as 1771kcal for PC, 2139kcal for EC, 2475kcal for HS, 2276kcal for CS, 1860kcal for 30-49 years, 1715kcal for 50-69 years, 1326kcal for over 70 years. The subjects of PC, EC, HS, and CS groups got about 25% of energy from fat, but the subjects in 30-49 years, 16%, those in 50-69 years, 15%, and those over 70 years, 13%. The energy consumption from protein was about 15% in each age group. Percent of energy intake as Korean RDA was greater than 100% for PC, EC, HS, and male CS groups. The percent intake for RDA of calcium, iron, vitamin A, and vitamin B$_2$was low in most age group. Iron intake was inadequate in female of PC and CS groups, and subjects in 30-49 years and over 70 years. Mean adequacy ratio(MAR) was 0.9 in PC, and decreased with increase of age. Therefore MAR did not reach to 0.7 among subjects over 70 years. Index of nutritional quality(INQ) for calcium, iron, vitamin A, and vitamin B was below 1 in most age groups. From these results, major nutritional problems of each age group were overall inadequate intakes of calcium and iron, excess consumption of protein and fat for PC, EC, HS, and CS groups, and inadequate nutrients intake of subjects over 70 years old. According to these results, each age group seems to need specific nutritional intervention. (Korean J Nutrition 34(5) : 554~567, 2001)

This study was conducted to identify the characteristics of Korean diet in the view of food and food group intakes. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Rice was a major contributor to many nutrients intake because of the amount of consumption. Vegetable oil made great contribution to fat intakes and eggs, squid, and anchovy supplied much cholesterol compared to other foods in all the age groups. Milk was major contributor of fat and cholesterol as well as calcium in younger age group, and seasoning gave much contribution to iron intakes. Mean dietary variety score(DVS) was 32 for EC group and 17 for subjects over 70 years, and tended to decrease along the increasing age. EC group consumed most variable number of foods of all groups but they consumed many junk foods, therefore the MAR value was low despite their high DVS value. Mean dietary diversity score(DDS) of each age group from PC group to subjects over 70 years was 4.34, 4.28, 3.79, 3.89, 3.76, 3.56, and 3.25, respectively. Food group, which was consumed below the minimum amount, was mainly fruits in all the age groups, and many subjects in HS group and over 30 years consumed dairy products below the minimum amount. From these results, age specific nutritional problems were found. PC group and subjects over 50 years seemed to need more diverse food intake than now, EC group did nutrient dense food, and HS group and subjects over 30 years did dairy products. Also, subjects took various nutrients from rice and seasoning contributed to some nutrients intakes. (Korean J Nutrition 34(5) : 568∼579, 2001)
