The Republic of Korea Army predicted that the continuous decline in fertility rate and the low birth rate, one of the biggest issues in our society, would lead to a security crisis due to a lack of military personnel, and revised the Military Service Act in 2010 to prevent enlistment of 'clearly mixed races', which had previously restricted enlistment. made it compulsory As a result, 50 children from multicultural families enlisted in the military in 2011, and the Military Manpower Administration at the time predicted that more than 8,000 people would enlist every year after 2020. This poses another challenge for the Army. A lack of understanding and respect for different languages, religions, and eating habits can lead to conflict among members, which will lead to weakening of combat power. Therefore, through a case study of multicultural application by world powers, the history of success and failure of respect for multiculturalism and the current policy of respecting multiculturalism of the U.S. Army are studied to examine the direction of our army.

The purpose of this study was to identify the contents that students want to learn the most on Home-Economics. Participants were 710 middle school students(359 boys and 351 girls) from 9 schools located in 4 cities and 5 counties in CholaBukDo. The results are as follows: 1. Of 32 contents on Family life, boys were interested in 'the puberty', 'pregnancy and the ethics on sex', 'social needs', 'the importance of family relationship', and 'adolescents' physical development'. On the other hand, girls were more intered in 'pregnancy' and 'the ethics on sex', 'the puberty', 'development of career consciousness' and 'career preparation', 'the adolescents' physiolosical and physical development', and 'the importance of family relationship'. 2. Of 37 contents of Managing home resource and Consumer life subarea, boys showed their interests on 'environmental problems', 'environmental conservation', 'environmental pollution', 'management of time and work', 'knowledge', 'management of their abilities'. And girls were more interested in 'environmental conservation', 'environmental pollution', 'environmental problems', 'adolescents life', and 'management of time and work'. 3. Of 49 contents on Dietary life, boys were more interested in 'puberty and the development', 'importance of nutriment', 'nutrition and health' and 'smoking and the health'. However, girls were more interested in 'smoking and health', 'puberty and the development', 'the importance of nutriment', 'nutrition and health', 'a realistic plan to reduce the food-based environmental pollution'. 4. Of 40 contents on Clothing life subarea, while boys were interested in 'the suitable cloths on oneself', 'clothing design', 'regulation of temparature', physical protection' 'merchandising for ready-made clothing'. On the other hand, girls were mostly interested in 'the suitable cloths on oneself', and next 'the clothing design', 'merchandising for ready-made clothes','physical protection', and 'the appropriate posture and physical adornment'. 5. Of 18 contents on Residence life subarea, teachers emphasized the importance of ventilation for adjusting the room environment and students were more interested in the effective use of the residing space. In general, those middle school students in Cheolabukdo showed the biggest interest on 'Clothing life', 'Residence life' the second, 'Eating life' the third, 'Human development and Family relationship' the fourth, and Management of family resource and Consuming life' was their fifth interest. Such result was consistent with Ⅱ-Rok Park's previous research(1997). Since the participants for this study were sampled form 9 schools located in CheolaBukDo, it is not suitable to apply the results nationwide. The restricted sampling must be considered and further studies are needed to make comparisons among areas.

Studies were carried out at the National Institute of Animal Nutrition and Physiology, India to determine the effect of feeding chopped paddy straw (Oryza sativa) on the energy expenditure in crossbred cattle. Four crossbred cattle male, aged 5-6 years and weighing about 450 kg were used for this study. Three experimental trials, one each for the feeding of un-chopped paddy straw offered ad libitum (UCA), chopped paddy straw fed at restricted level (CR) and chopped paddy straw offered ad libitum (CA) were conducted. The quantity of un-chopped paddy straw consumed during UCA was assumed as the voluntary intake by the cattle and the same quantity was offered after chopping during CR. Each trial comprised of 21 d preliminary feeding period and 5 d of observation recording period. Expired gas was collected in Douglas bags using a face-mask and three-way valve at 6 hourly intervals i.e., at 09.30, 15.30, 21.30, and 03.30 h throughout the observation period. Expired gas and ambient air inspired by the animals were analyzed for the oxygen content through paramagnetic oxygen analyzer. Energy expenditure (EE) by the animals was calculated by determining the volume of oxygen consumed per minute (STP) and multiplying by 4.825. Paddy straw used in all the three trials contained (g/kg DM) 90.0 CP, 786 OM, 700 NDF, 489 ADF, 357 Cellulose and 60.0 ADL. Metabolizable energy (ME) was 6.9 MJ/kg DM. Dry matter intake (DMI) both in UCA and CR was about 6.8 kg, except that it was chopped in CR. Chopping has resulted in 32% improvement (9 kg) in DMI of CA as compared to that of UCA. Although ME intake was similar in UCA and CR (47.2 MJ/day), energy expenditure (EE) was higher in UCA (23.3 MJ) when compared to that of CR (19.5 MJ). The ME intake (63.3 MJ) as well as EE (27.1 MJ) was highest in CA. Energy expenditure when expressed as MJ/kg DMI was 3.48, 2.90 and 3.12; whereas as per cent of ME intake it was 50, 41 and 44 in UCA, CR and CA respectively. Our study has unequivocally confirmed that chopping of poor quality roughages like paddy straw has definite advantages not only in terms of improving the intake by decreasing the time taken for ingestion but also in reducing the energy cost of eating.
