This study describes measurements of fast ice recorded on May 23, 2009, in Kongsfjorden (translated as ‘Kongs Fjord’), an inlet on the west coast of Spitsbergen in the Svalbard Archipelago. Seasonal fast ice is an important feature for Svalbard fjords, both in relation to their physical environment and also the local ecosystem, since it grows seaward from the coast and remains in place throughout the winter. Ice thickness, snow, ice properties, and wind speed were measured, while SAR (Synthetic Aperture Radar) data was observed simultaneously observed two times from ALOS-PALSAR (L-band). Measured ice thickness was about 25-35 cm while the thickness of ice floe broken from fast ice was measured as 10-15 cm. Average salinity was 1.9-2.0 ppt during the melting period. Polarimetric data was used to extract H/A/alpha-angle parameters of fast ice, ice floe, snow and glacier, which was classified into 18 classes based on these parameters. It was established that the area of fast ice represents surface scattering which indicates low and medium entropy surface scatters such as Bragg and random surfaces, while fast ice covered with snow belongs to a zone of low entropy surface scattering similar to snow-covered land surfaces. The results of this study will contribute to various interpretations of interrelationships between H/A/alpha parameters and the wave scattering Phenomenon of sea ice.

This experiment was conducted to compare the nutritive values of locally produced oil meals for egg-type growers from 6 weeks to 21 weeks of age. Six hundred White Leghorn chickens of Hisex strain were devided into two groups, i.e. group A (partial substitution for soybean oil meal) and group B (complete substitution for soybean oil meal). The group A and B were splited into 5 treatments, namely, soybean oil meal (SBOM), perilla oil meal (POM), sesame oil meal (SOM), rapeseed oil meal (ROM) and corn gluent meal(CGM), respectively. The results obtained are summarized as follows. 1. There were no differences in body weight gain, feed intake and feed efficiency during the growing period of 6-21 weeks among treatments. The body weight gains obtained during the total growing period including the starter period (Exp` 5) of CGM, SBOM, POM, SOW and RoM fed chicks were 1604.0, 1603.0, 1582.7, 1542.6 and 1513.6g in the group A and 1578.8, 1568.3, 1518.8, 1476.2 and 1484.6g in the group B, respectively. The mean values of body weight gains during the total growing period in the group A and B were 1569.1g, 1525.3g and of feed efficiency in the group A and B were 7.08, 7.25, respectively. 2. No differences in nutrients utilizability during the growing period of 6-21 weeks was observed among treatments. It was found that the rate of nitrogen retention was somewhat decreased gradually toward the maturity of chicks progressed.

The current study was undertaken to evaluate the effects of a locally-produced recombinant porcine somatotropin (pST) on growth perfermance and pork quality of finishing pigs. A total of 32 barrows weighing average 61kg were employed for the 6-week growth trial : 8 barrows were allocated into the control group (CONT): 8 barrows into the slow release-low dose pST group (SR-L); 8 barrows into the solve release - high dose pST group (SR-H); 8 barrows into the daily pST group(DAILY). CONT pigs received no pST. SR-L and SR-H pigs were treated with pST twice during 6 week trial(Each dose contained the pST equavalent to 50 ㎍ and 100 ㎍ per day, respectively). DAILY pigs received 100 ㎍ pST/㎏ B W daily. All pigs were fed a commercial feed containing 0.87% lysine ad lib. There was no significant difference in average daily gain among treatments. Feed/gain was reduced by 20% in DAILY (3.09 vs 3.85; p$lt;0.05) and 11% in SR-H (3.43 vs 3.84; p$lt;0.05) compared to the CONT. Backfat of the DAILY group was 20% thinner than that of the CONT and loin eye area was wider by 17% (p$lt;0.05) in DAILY group, compared to the CONT. The extent of the improvement in growth perfermance of SR groups was less (p$lt;0.05) than that of DAILY group. There were no significant differences in the color, juiciness, flavor and texture of pork among treatments, with the tenderness of DAILY group being less desirable compared to that of CONT group. Moisture content of DAILY group was higher (p$lt;0.05) than that of CONT group, while lipid content was reduced in DAILY group. SR group showed the middle values between CONT and DAILY group in most criteria on growth performance and pork quality investigated. These results indicated that the recombinant pST produced by LG Chem., Ltd., Korea stimulated growth performance in growing pigs and did not show any major negative effects on pork quility, suggesting that slow release pST could be used as a growth stimulant for growing pigs.
