This experiment was conducted with four heads of castrated Landrace swine to compare the effects of ground, steamed and soaked barley on digestibility, nitrogen retention and rate of gain for 65 days. The results obtained in this study are as follows. 1. When the ground barley was fed, the digestibilities of crude protein and crude fiber were 58.35% and 39.72%. DCP and TDN calculated on this base were 8.40% and 58.35% These figures were statistically significant when compared to other treatments. However, there was no significant difference between the treatments when a Nretention was compared. 2. The average weight gains of pigs, during the test period, fed ground barley, steamed barley, soaked barley were 3.0, 2.8, 2.9 ㎏ respectively. They seemed to be paralleling with digestibility.

In this study, the panel whose thickness is satisfied with 2012 housing design standard was selected, and its Thermal Performance was evaluated in order to apply Structural Insulated Panels to house. Test result shows that Thermal Conductivity is satisfied with the 2012 standard (0.225W/㎡ · K) and is assessed as a suitable material to apply for houses.

In this study, the work attitude of flight attendants who were performing emotional labor, had been explored. The organizational support system had been analysed to test its effect as a moderator on increasing positive job attitudes. It was found emotional labor had influence on work attitude of flight attendants. Emotional labor consisted in this study deep acting and surface acting. First, deep acting found positively related with job satisfaction and organizational commitment, negatively related with intention to leave. Second, surface acting negatively related with job satisfaction and positively related with intention to leave. This study put organizational support systems as moderator. First, Training has moderating effect on the relationship between deep acting. Organizational support has moderating effect on the relationship between deep acting, intention to leave. Counselling has moderating effect on the relationship between deep acting, job satisfaction. Peer support has same effect on the relationship between deep acting and intention to leave.

To evaluate the effect of feeding level on daily gain, feed efficiency and carcass composition, high (H: DCP and TDN was supplied for 1.1㎏ daily gain × 1.1) and low (L: DCP and TDN was supplied for 0.6㎏ daily gain × 1.1) level nutrient were fed to each 12 heads of Korean native bulls (KNB) for the 1st period (body weight from about 120㎏ to 300㎏), and thereafter during 2nd period 12 heads were devided into two groups and fed with H and L-feeding level until animals weighted about 500㎏. 1. Daily gain was significantly increased (P$lt;0.05) and the feeding period was significantly decreased when fed with H level. Shifting feeding level (H→L or L→H) did not affect the daily gain during whole period although there was a trend that H level during 1st period was more efficient than L level. 2. Dry matter intake was higher with H level than with L level. 3. DCP efficiency was better when fed with L level. The efficiency of L→H level was lower than that of H→L level during whole period but was better than that of H→H level during the early phase of 2nd period. 4. TDN efficiency was not influenced by the feeding level. However, TDN efficiency of H group was slightly better than that of L group during the 1st period. 5. Dressing percentage was significantly increased when fed with H level during the 2nd period. Fat content was significantly increased when fed with H→H level, while there was no significant differences among H→L, L→H, L→L feeding levels. There was no significant differences in retailed cuts between the feeding levels. 6. Carcass price was higher and feed cost was lower when fed with L level during the 2nd period. The monthly income per head was higher when fed with H level during the 1st period, although there was no big differences between H→H and L→H feeding level.
