We present the results of using small telescopes in the United Arab Emirates (UAE) for observing variable stars and asteroids. Two telescopes, namely, 5" apochromatic refractor and 14" Schmidt-Cassegrain, at Al-Khatim Observatory (M44) were used for the observations. The targets were the three variable stars RR GEM, AG LMi, and DL CMi and the asteroid 22 Kalliope. We found a good consistency between our light curves and published ones for the calibration targets, i.e., the asteroid 22 Kalliope and the variable star RR GEM. According to previous studies, AG LMi has two suggested periods, 16.3 hours and 32.62 hours. Our results clearly confirm the second one, with a period of 32.6175 hours. The star DL CMi has several suggested periods as per previous studies, such as 4.0173 days, 1.9606 days, and 2.0086 days. Our observations confirm the first one, with a period of 4.0159 days. These results demonstrate the effectiveness of using small telescopes for observing variable stars and asteroids. This work provides some recommendations on using small telescopes for such observations.

The purpose of this study was to assess the nutrition education program for older adults at rural area. Eighty three adults (mean age ;55.6$\pm$11.9) participated in nutrition education program. Data collection includes serum and urine collections for health state. The impact of nutrition KAP (knowledge attitude and practice) and retention was examined among participants who were assessed at program entry 3 times of education and 1 month of follow-up. The results were as follows : The participants were composed 52 persons of under 60-year-old and 31 persons over 60 years. Of the 83 participants, 60 were females and 23 were males. Serum albumin and calcium content of females (3.5$\pm$1.2g/dl, 7.5$\pm$3.9mg/dl) were significantly lower than males(4.7$\pm$0.9g/dl, 11.2$\pm$4.6mg/dl). Serum TG and cholesterol contents of females (143$\pm$117mg/d1, 205$\pm$31mg/d1) were higher than males (101$\pm$86mg/dl, 192$\pm$19mg/dl) but not significantly different. The calcium (13.4$\pm$9.0mg/dl) and urea (743$\pm$440mg/dl) contents of urine excretion were also significantly lower in female than in males (19.7$\pm$11mg/dl, 1041 $\pm$535mg/dl). Via the question of nutrition attitude, the participants improved significantly between pre and post education (the score of pre, post and after 1 month, 6.7$\pm$1.8, 7.2$\pm$1.5, 7.2$\pm$1.8), and were also attributed to better personal feeling health by modified CMI test but food habit was not significantly improved. As the differences of age and gender groups were compared, under 60-year-old group had better nutrition practice score than over 60 years group.
