This study was aimed at knowing the recognition of teachers' nutrition knowledge and nutrition education at day-care centers in Seong-nam. Teachers were all female, most of whom were in the 20, and their careers were less than 3 years. And $76.2\%$ of the teachers graduated from high school and junior college. The score of the nutrition knowledge was average $14.3\pm2.2$ (out of 20). It shows that they are lack of general information of nutrition. As the teachers had higher education, they scored higher nutrition knowledge levels (p < 0.01). It also says that there was meaningful interrelationship between the nutrition knowledge and the number of children they had (p < 0.05). $93\%$ of the teachers said that nutrition education should be given when children are three years old, at least and most of the teachers thought that nutrition education is necessary and should be taught in a separate course. $50.4\%$ of the teachers thought that nutrition education for early childhood should be taught by a nutritionist, but $35.2\%$ of them thought that the teachers themselves should be in charge of it. About $60\%$ of the teachers thought that 'Cooking Activity for Early Childhood' course should be established and it is desirable that the nutrition education should be in the area of cooking activity for childhood at day-care centers. The teachers thought that dietary habit is the most important subject in nutrition education and they got more information from the internet rather than in the class related to nutrition.

This experimental study was executed to obtain basic data for actual engine operation using radical induced ignition method (RI) which can achieve emission reduction and high efficiency due to the rapid bulk combustion. In this study, a direct injection diesel engine was converted into SI type engine with a sparkplug. The modified SI type engine can be divided into two classes. One is the SI engine with a sparkplug only at the cylinder head, and the other is the SI engine with the sparkplug which is enveloped in a sub-chamber. Also, a basic experimental was conducted in order to investigate combustion mechanism of radical induced injection before the experiment execution for actual engine using the modified SI engine. The bulk combustion phenomenon of radical induced ignition method was analyzed from the basic experiment by using a constant volume chamber. Volume value of sub-chamber used in this experiment is approximately $0.2\%$ of one of the main combustion chamber. In this paper, combustion characteristics using radical induced injection method was compared with that of using spark ignition method according to change in the engine speed and equivalence ratio. As a result, in the case of the radical induced injection engine, the combustion duration and cycle variation were respectively reduced ranged from $\Phi$(equivalence ratio)=0.8 (lean mixture ratio) to $\Phi$=1.0 (stoichiometric ratio).

본 연구에서는 문맥 정보를 함께 고려해야만 인식할 수 있는 단어 오류에 대하여 오류 인식 방법과 수정 후보 생성 방법을 제안한다. 이 문제는 기존의 영어권에서 이미 많이 다룬 연구 주제이다. 본 연구에서는 영어 자동채점 시스템에서 사용하도록 특화된 방법을 제안한다. 문맥 정보를 고려한 단어 오류 검사에서는 자주 혼동되어 사용되는 단어집합(confusion set)을 활용한다. 비영어권 사용자의 작문 특성을 반영하기 위해 기존의 영어권에서 구축한 혼동집합 이외에 자동으로 혼동집합을 구축하여 실험해 보았다. 또한 품사 중의성으로 인해 기존의 구문오류 검사기가 다루지 못하는 오류를 정의하고 오류 인식과 오류수정 후보를 생성하는 방법을 제안한다. 실제 한국어가 모국어이면서 초/중급 작문 수준의 수험생들이 작성한 영어 문장에 대해 평가해 본 결과, 약 70.48%의 f1 값을 얻어 기존의 영어권 결과에 비해 뒤지지 않는 성능을 보였다.

The objective of this research was to explore the influences of 'having a meal with someone' on individuals' eating pattern. Eating is not a simple matter of energy intake but also serves to anchor daily routines being cultivated by people and society. This study was conducted using a cross-sectional eating behavior survey of university students (N = 893, 380 men, 513 women) aged 20 to 24 years. Results were analyzed and presented as frequencies, means and ${\chi}^2$-test with SPSS 14.0. Differences in dietary habits by commensality and solo-eating were observed; Students who ate alone, spent 15 min for a meal and ate convenience food items when they didn't feel hungry. Compared to students who ate alone, those who ate together with someone spent 30 min for a meal and ate more amount of food. Eighty percent of respondents ate more various menus in commensality than solo-eating. They felt lonely when they ate alone and preferred to eat together. In conclusion, university students start to decide and select their own meals by themselves after junior and high school food services which are fixed with regard to menu and the amount. Dietary habits of Koreans rapidly changed concomitant with social changes over the past half century. Governments and health experts recognize that unbalanced meals cause lifestyle-related diseases, in particular obesity. Our research findings will contribute to more comprehensive efficient nutrition education programs in order to prevent obesity and other lifestyle-related diseases in early stages of adulthood.

There has been a rapid growth in Korea since 1962 because of the success of the 5-year Economic Plan. The number of industrial work and workers has also made had a rapid increase. Consequently, the management of occupational health for the purpose of promoting health in industrial workers is needed especially in the health examination program. The purpose of this study was to analyze the Knowledge, and Attitude among industrial workers of health examination programs. The target population was 402 industrial workers from 4 factories in Kangwon province. A survey was conducted to collect data by a self administered questionnaire from October 29 to November 5. A sixty four item questionnaire was designed to collect data concerning Knowledge, and Attitude of health examination of industrial workers. The data was analyzed by means of percentage, mean, T-test, ANOVA, Pearson's correlation coefficient. The major findings were as follows : 1. The respondents presented the following picture : The male population was 88%. 57% of respondents were age 25-34 years old. 69.4% of respondents were married. 73.4% of respondents were high school graduates. 80.8% of the respondents were working over 48 hours per week. The respondents with over 10 years on the job were 31.9% of the respondents. Health examination were given to the respondents as: pre-employment health examination 90.5%, general health examination 91.5%, and special health examination 31.5%. 2. The Knowledge level was different in health examination items. 80.5% of respondents had knowledge about hearing test, body weight, visually, chest X-ray like simple things. Below 50% of respondents had knowledge of urine test, liver function test, and career history. 3. Attitude status about health examination showed an average score 36.5(median 33) of satisfaction, 26.93(median 21) of importance, 13.84 (median 21) of content, 10.46(median 12 of reliability on health examination results. 4. The level of Attitude on health examination was significantly different than the Knowledge level. 5. The relationship among stated variables such as satisfaction, the perceptions of importance on health, health examination, the result and follow up after health examination were shown to reflect neither positively nor negatively on each other.
