The purpose of this study was to investigate foodservice satisfaction in high school boarding students in Busan. To achieve the research objectives, a questionnaire was distributed to 357 students at four high schools in Busan. From the results, 83.8% of students ate breakfast every day, and more female students ate breakfast daily compared to male students (P<0.05). However, 53.2% of students ate 'almost-all' amounts of breakfast compared to lunch (86.6%) and dinner (87.5%). The average students' foodservice satisfaction score was 4.04/5.00. The highest satisfaction category was sanitation, followed by the service and food categories. Freshmen showed significantly higher foodservice satisfaction than junior students in terms of service (P<0.05), sanitation (P<0.05), and food categories (P<0.01). As for satisfaction of each meal, breakfast scored 3.15, lunch scored 4.04 and dinner scored 4.12, whereas male students showed significantly higher satisfaction than female students in breakfast (P<0.05) and dinner (P<0.05). Freshmen showed significantly higher satisfaction than juniors in breakfast (P<0.001), lunch (P<0.001), and dinner (P<0.001). As for meal type preference of each meal, female students strongly preferred Korean food for breakfast (P<0.01). This research suggests that it is necessary to improve breakfast satisfaction by developing a variety of menu items.

This study aims to present a fundamental data base to figure out the mental and the physical conditions that the dental technicians are facing and ultimately to develop a health care program to deal with their health related problems. To this end, we took an analysis on the health status among the subjects of 895 dental technicians currently working at the dental lab around the nation from January 15 to March 31, 2009 by way or Todai Health Index(THI). Of the average scale point in accordance with 12 scale scores of the physical and the mental subjective symptom, the results revealed that the physical appeals (21.10) were higher than the mental appeals (18.49) and the multiple subjective symptom was marked as 38.44 followed by the mental irritability (25.92). In gender differences, the females proved to be higher than the males in both physical appeals and mental appeals while the physical appeals were dominant in both genders. The physical appeals were higher than the mental appeals with regard to the general characteristics. In the case or the group or age twenties as shown in the physical and mental average scale point, the other groups showed 21.55% of the physical appeals among the married whereas the mental appeals showed the highest point as 18.70 in the unmarried group. In job position, the other groups marked the highest, in working condition, below average group marked the highest, in frequency of break time, none group marked the highest. We drew a conclusion form this study that the dental technicians gained the higher points in the item or the multiple subjective symptom, the menial irritability, and the irregular life. More research on th is phenomena should be followed along with the development of various and practical health care programs to promote the health or dental technicians.

An experiment was conducted to evaluate a ventilation system, which was devised to encourage farmers to use the enclosed growing and finishing pig housing system. A roof-air-entry ventilation system in winter and a side-wall-air-entry system in summer were evaluated. Air flow rate on the floor level which is the low part of pen and the living area of pigs in the enclosed growing and finishing pig house during winter was measured at 0 to 0.19 m/s at the minimum ventilation efficiency of 1,440 $m^{3}/h$. During summer the air flow rate was detected at 0.07 to 0.42 m/s at the maximum ventilation efficiency of 24,000 $m^{3}/h$. Therefore, it is concluded that the side-wall ventilation system is suitable for growing and finishing pigs in the enclosed house during the days of mid-summer and the roof-ventilation system was suitable during the coldest days of mid-winter. In addition, although the enclosed pig house has the system in which air exhausts through only one side wall, air should enter through both-side walls for the better ventilation performance.

The more growing on home automation system at automatic control, the more efficiency required for energy consumption and for recycling energy in near future. Heating is essential in general apartment. Heating method is two types in apartment. One uses electricity, and other one uses warm water. If use electricity, is not efficient by rise of electric charges. But, It can reduce much in expense aspect, if use warm water. When use warm water, temperature of warm water is not equal from all pipe parts. Therefore, indoor tempera can be unequal with set point. Solution of these problems is as following. Temperature sensor in warm water attach pipe. The measured temperature transmits by real time. Temperature of warm water controls in receiver side. In this paper, we propose an automatic temperature transmission system for the heating pipe at home, that is a low-power based, and supply the energy source from a small AC motor resided in bottom cement mortal. The proposed system is used in power mechanism from a collision process of water-jet using propeller water-difference and also designed a CPU module by Atmega8 at ATMEL co., Inc. and a communication module by CC1020 at Chipcon co., Inc.
