Many works have been reported in various fields on the subject of controlling a robot with high-level robot languages. This paper presents one such effort and explains the development of an automatic robot programming system which utilizes the concept of the task level language. This system is expected to act as an intelligent supporting tool in robot programming and be put into practical use. Emphasis is placed on the role of the programming system as a tool that generates the executable robot program according to the user specified tasks. Several task level commands are used in the developed system, and the resulting inflexibility is complemented by the motion level commands of the motion level robot languages. Thus, the advantages of both task and motion level languages are utilized, and no knowledge of specific language grammer is needed even when using motion level commands. To increase the usability of the developed system, various methods are provided for supplementing the programming system using taught data.

Practicality and value of mathematics can be verified when different problems that we face in life are resolved through mathematical knowledge. This study intends to identify whether the fraction teaching is being taught and learned at current elementary schools for students to recognize practicality and value of mathematical knowledge and to have the ability to apply the concept when solving problems in the real world. Accordingly, contextual problems and noncontextual problems are proposed around fractional arithmetic area, and compared and analyze the achievement level and problem solving processes of them. Analysis showed that there was significant difference in achievement level and solving process between contextual problems and noncontextual problems. To instruct more meaningful learning for student, contextual problems including historical context or practical situation should be presented for students to experience mathematics of creating mathematical knowledge on their own.

This study was conducted with the goal to identify the degree to which elementary school students' knowledge about personal information protection practices impacted their actual behavior with regard to privacy protection. To fulfill this goal, knowledge about personal information protection was set as (1) knowledge about concepts of personal information, (2) knowledge of the rights of information holders, (3) knowledge about the code of conduct for information protection, and (4) awareness of the value of personal information. As for students' behaviors to ensure their personal information protection those were set as their habits to comply with the personal in-formation protection code of conduct and their efforts to respond and recover from any personal information violation. This study was conducted targeting 510 elementary students. The degree of the students' knowledge and their behaviors was measured by first distributing a self-report survey to the students and then analyzing their responses. The results of the analysis revealed the following: First, it was found that there are no differences among the four factors of knowledge and behavior according to the status of their education. Second, the two factors that primarily affected their personal information protection behavior were found to be their awareness of the information protection code of conduct and awareness of the value of personal information.

Listening comprehension can be defined as a process of an integrative, positive and creative activity through which listeners get the message of speakers' production using linguistic or non-linguistic redundancy as well as linguistic or non-linguistic knowledge. Compared with reading comprehension, it has many difficulties especially for foreigners. while it can be transferred to the other skills: speaking, reading, writing. With this said, listening comprehension can be taught effectively using the following teaching strategies. First. systematic and intensive instruction of segmental phonemes, suprasegmental phonemes and sound changes must be given to remove the difficulties of listening comprehension concerned with the identification of sounds. Second, vocabulary drill through various games and other activities is absolutely needed until words can be unconsciously recognized. Without this, comprehension is almost impossible. Third, instruction of sentence structures is thought to be essential considering grammar is supplementary to listening comprehension and reading comprehension for academic purpose. So grammar translation drills, mechanical drills, meaningful drills and communicative drills should be performed in succession with common or frequently used structures. Fourth, listening activities for overall comprehension should teach how to receive overall meaning of intended messages intact. Linguists and literatures have listed some specific activities as follows: Total Physical Response, dictation, role playing, singing songs, selective listening, picture recognition, list activities, completion, prediction, true or false choice, multiple choice, seeking of specific information, summarizing, problem-solving and decision-making, recognization of relationships between speakers, recognition of mood, attitude and behavior of speakers.

The purpose of this study was to find out how much they have several aspects of food related knowledge and eating behaviors of high school students in Sungnam area. The self-administrated questionnaire was used. The result were as follows: 1. The average height of boys and girls was $172.6{\pm}0.7$ cm and $156.3{\pm}1.5$ cm respectively. The average weights of them were $62.4{\pm}0.5$ kg (male) and $47.2{\pm}0.8$ kg (female). BMI (Body Mass Index) of them were $20.74{\pm}0.14$ (male), $18.82{\pm}0.28$ (female). The average age is 16.7 years old. 2. The 66.5% of the subjects were spent more than one-third of their pocket money in buying on light meals during three times a week. There were significant differences between income level of family. Boys spent more money on each meal than girls. And significant differences were also obserbed by their residence area and Bundang residences spent more in buying snacks. 3. The rate of skipping meals was 51.2% in boys compared with 68.0% in girls. The frequencies of buying snacks instead of main meal were high in girls. Time limits in eating may possibly be the main reason for skipping meals (59.8%), especially in the morning. Skipping a breakfast becomes general eating habits in high school students, because of pressure for time to go to school. 4. It is required that parents should be taught to prepare balanced lunch box for their children because the rate of students who prepared two lunch boxes are 49.4%. 5. The students took snacks once or twice a day. They usually bought snacks in school concessions (51.8%) and they selected items of snack instinctivly. The girls ate snacks during lunch break time (31.7%) and after dinner (23.6%). Boys ate snacks after dinner (29.1%). Preference of foods were different by sex. Boys preferred bread (31.7%), milk and otherdairy products (80.8%), cola and soda (42.0%) as their snacks between meals. Girls selected biscuit, chip, beverage, coffee as their snacks, frequently. 6. BMI value of the group who ate between meals more than three times a day was lower $(18.78{\pm}0.65)$ than that of the group who ate nothing between meals $(20.71{\pm}3.79)$. 7. As for the nutritional knowledge, the students generally had higher correct rate of answer about which nutritive components of food has (76.6%). But they had lower knowledge on questions of nutritive values in food (10.6%). There was a meaningful relation between favorite food and nutritional knowledge. In conclusion, there were some problems on nutritional knowledge and eating habits among the high school students. Therefore, it was required that girls should be learned to recognize the importance of breakfast and needed to select balanced meals and snacks. And it was required that the nutrition education should be complemented to motivate and improve practical eating behaviors.
