This study investigated the effect of taste preference(sweet, sour, salty, hot) on anthropometric measurements and nutrient intakes of 256 primary school children in Kwangju. There was no significant difference in the anthropometric measurements according to the sweet taste preference. Height, weight, triceps, abdomen, and chest circumferences of the group preferring a sour taste, however, were significantly lower than those of the other groups. The height of the group preferring a salty taste was significantly shorter than that of the other groups and there was a tendency toward high systolic blood pressure and diastolic blood pressure. The waist circumference of the group not preferring the hot taste was larger than those of the other groups. There was no significant difference in the energy intake according to the sweet taste preference. The protein intake of the group preferring a sweet taste as significantly lower than that of the other groups. The fiber intake of the group preferring a sour taste was significantly higher than that of the other groups. There were no significant differences in the nutrient intakes according to the salty taste preference. The energy intake of the group preferring a hot taste was lower than that of the other groups. The results show that children's taste preferences influence anthropometric measurements and nutrient intakes. These results suggest that children's eating behaviors are in needs of correction. The findings of this study should be applied to nutrition education to ensure better physical fitness of children.

Distributed Autonomous Robotic System (DARS) is defined as a system that independent autonomous robots in the restricted environments infer their status from pre-assigned conditions and operate their jobs through the cooperation with each other. In the DARS, a robot contains sensor part to percept the situation around themselves, communication part to exchange information, and actuator part to do a work. Especially, in order to cooperate with other robots, communicating with other robots is one of the essential elements. Because Bluetooth has many advantages such as low power consumption, small size module package, and various standard protocols, Bluetooth is rated as one of the efficient communicating technologies which can apply to small-sized robot system. In this paper, we will develop Bluetooth communicating system for autonomous robots such as DARS robots. For this purpose, The Bluetooth communication system must have several features. The first, this system should be separated from other robot parts and operate spontaneously and independently. In other words, this communication system should have the ability to organize and maintain and reorganize a network scheme. The next, this system had better support any kinds of standard interfaces in order to guarantee flexible applicability to other embedded system. We will discuss how to construct and what kind of procedure to develop the network system.

In an attempt to take Comprehensive nursing care the author tested cognitive function and psychiatric disturbance produced by normal adults. Mini-mental state and simple reaction time were tested and general health questionnaire was conducted two hundred subjects. The data were analyzed statistically and the results follow: 1. The score of mini-mental state of the elderly group was less significant than that of the younger group in the tests of cognitive dysfunction. The score of MMS of the female group, the illiteracy group less significant than that of other groups in the test of cogntive dysfunction. 2. Reaction time of the elderly group was slower than that of the younger group. Reaction time of the female group was slower than that of the male group. Reaction time of the illiteracy group was the slowest & the unskilled group was slower than that of the other groups. 3. As a result of the results of psychiatric disturbance the score of general health questionnaire of the elderly group was significantly higher than that of the younger group in the tests of psychiatric disturbance. The test of psychiatric disturbance sho-wed that the score of general health questionnaire of the female group was significantly higher than that of the male group in the tests of psychiatric disturbance. The illiteracy group was the highest in the psychiatric disturbance among other groups and the unskilled group was significantly higher than the other groups. 4. Education had higher correlation to mini-men-tat state, while age negative correlation in comparison with other variables age had higher correlation to reaction time, while education had negative correlation in comparison with other variables. Sex had low correlation in these tests.

This studies were designed to know the contents of trace element and magnesium in cereals. Twenty two kinds of cereal, 104'samples, were analyzed by atomic absorption spectrophotometer for the determination of Manganese, Iron, Magnesium, Chrome, Cupper, Nickel, Zinc, Stannous, Lead and Cadmium. The results are as follows: 1) The contents of Mn and Fe in the sesame group show highest value and next is bean group. In the rice group its content shows lowest value than other cereals. 2) In the Cr content its value is lower than other elements in cereals respectively. Cr content of sesame and bean group show higher than rice and barley group. 3) The contents of Cu and Ni in the sesame and bean group show higher value than the value of rice and barley group. Its contents of rice and barley group is almost equal in Cu and Ni. 4) For the Zn content the value of sesame group is higher than other cereals and next is bean group. In the Sn content the value of bean group shows higher one than other cereals. The contents of Zn and Sn in rice and barley group are lower than other cereals. 5) The value of Pb is almost equal to each cereal. The content of Cd in bear group and barley group show higher than other cereals and its value of rice group is equal to the value of barley group.

A study was conducted to compare the quality characteristics among commercial broiler, Wangchoo (imported dual purpose breed) and Korean native chicken(KNC). Thigh and breast meat of the broiler(7-wk old), Wangchoo(15-wk old), and Korean native chicken(15-wk old) stored for 24 h at 5t were used to analyze chemical composition, physico-chemical characteristics, textural traits and sensory evaluation test. Crude fat and moisture contents in broiler meat and crude protein content in KNC were significantly(P<.05) higher than those in the other breeds regardless of parts of the body. Total collagen content in broiler meat was significantly higher than those of the other breeds, however, the heat-soluble and the acid-soluble collagen content in Wangchoo were significantly lower than those of the other breeds. Water-holding capacities of KNC in breast meat, and of broiler in leg meat were significantly higher than that of the other breeds, while the results of the water-holding capacity and the cooking loss were reversed. Myofibrillar fragmentation index in broiler meat was significantly higher than that in the other breeds regardless of body parts. Hardness, elasticity and cohesiveness in Wangchoo were significantly higher than those in the other breeds. The prominent fatty acids were oleic, palmitic and linoleic acids and run up to 79.03~83.82 %, regardless of breeds and parts. The sensory evaluation score of tenderness, taste and preference in Wangchoo were lower compared to the broiler and KNC, however, they were not significantly different between broiler and KNC. In conclusion, the quality characteristics of KNC were excellent compared to Wangchoo.

In this paper I investigate whether Korean-speaking children know the basic meaning of reciprocal anaphors like each other. I further examine whether they have knowledge of subtle differences in the interpretations of such anaphors depending on the two types of verbs. Fiengo and Lasnik (1973) pointed out a contrast between reciprocal sentences with active verbs and stative verbs. For example, a sentence with an active verb like The men in the room are hitting each other, has both a strong reciprocal reading (i.e., everyone of them in the room is hitting every other one) and a weak reciprocal reading (i.e., certain pairs of men are not engaged in the action of hitting each other). In contrast, a sentence with a stative verb like The men in the room know each other allows only a strong reciprocal reading (i.e., everyone of them know every other one). 16 Korean children and 15 Korean adults were tested using the Truth Value Judgment Task methodology. The results of the present study show that like English children, Korean children know the meaning of reciprocal anaphor, and that they also know the semantic difference of reciprocal sentences with active and stative verbs. Therefore, the present study strongly supports the claim that the semantic distinction of reciprocal sentences with active and stative verbs may be universal, and that children's ability of this semantic distinction might be innately given.

The purpose of this study is to examine the status quo of the networking between health promotion and other programs conducted by public health centers(PHCs), and to develop concrete strategies for improving the efficiency of the health promotion programs at PHCs. Data were collected from a questionnaire survey for 246 PHCs nationwide and 96 questionnaire were returned(response rate of 39%). A focus group study was also conducted to compliment the detail of the networking system between health promotion and other programs at PHCs. The results revealed that the current networking between health promotion and other programs conducted by public health centers is not working well. Especially, the communication networking between health promotion and other programs at planning stage is poorer than the stages of implementation, performance, and evaluation. The main reasons of the poor networking have been caused by an inadequate organizational structure, inefficient information system, low level of motivation for networking among the staff of PHCs, and no concrete guidelines for networking. This study also suggested several strategies to facilitate the cooperation between health promotion and other programs.

Objectives: This study aimed to examine how the relationship between socioeconomic factors at the macro level and suicide mortality rate of Korea was different from that of other OECD countries. Methods: We created OECD panel data of 29 OECD countries from 1985 to 2006 and analyzed the relationship between socioeconomic factors and suicide mortality rate for separate age and sex groups using a fixed-effect model. Economic factors included per capita GDP, per capita GDP growth rate, unemployment rate, and women's economic participation rate. Social factors included birth rate, alcohol consumption, and the percentage of population 65 and older. Results: Unemployment rate had a positive relationship with suicide in other countries but it had a negative relationship in some groups of Korea. Women's economic participation rate was both positively and negatively related with suicide in Korea but it did not relate to suicide in others. The negative relationship of birth rate and the positive relationship of alcohol consumption with suicide were evident in Korea, which were not found in other countries. The percentage of population 65 and older was negatively correlated in some female groups in Korea, while no significant relationship was found in other countries. Conclusions: Korea was substantially different from other OECD countries in the relationship between socioeconomic factors and suicide mortality rate.

Objectives: This study is aimed to illustrate the status of the occupational accident rate, fatality rate, and musculoskeletal disorder rate by safety and health management type in workplaces. Methods: In order to analyze the status of the occupational accident rate, fatality rate, and musculoskeletal disorder rate of different safety and health management types in workplaces, selected data from the Occupational Safety and Health Research Institute were used. Results: The occupational accident rate in workplaces where safety and health managers had been appointed was lower than in those where safety and health management was entrusted to other organizations, while the result was the opposite in regards to the fatality rate per 10,000 workers caused by accident. However, the occupational fatality rate per 10,000 workers in workplaces where safety and health managers have other roles was 426% higher than those where safety and health management was entrusted to other organizations. Moreover, the musculoskeletal disorder rate of the workplaces where safety and health managers have other roles was 15% higher than those where health management was entrusted to other organizations. Conclusions: It is necessary to review the effectiveness of systems in which safety and health managers can concurrently engage in other roles.

Objective: This study examined five- to six-year-old children's categorization of mixed-race faces and how it was affected by perceptual individuation training (PIT) for other-races. Methods: Sixty-five children attending classes for 5-year-olds in childcare centers were shown happy and angry faces of Korean and African American mixed-race people, along with neutral faces of Korean and African American monoracial people. They were asked to categorize the faces into same-race or other-race. After the pretest, participants received a PIT for either African American (other-race) or monkeys. Then the racial categorization task was administered again as a posttest. Results: Children showed no general tendency to categorize mixed-race faces as out-group in the pretest. Yet, the PITs further reduced children's categorization of mixed-race faces as out-group. In particular, the effect was clearly evident in children who received the PIT for other-race. Conclusion/Implications: The results suggest that the tendency to categorize mixed-race faces as an out-group may not be evident in early childhood and that experiences of perceptually identifying other-race individuals may help children view mixed-race individuals as being in the ingroup, at least perceptually.
