A survey of physical inputs was conducted on the total population of dairy farms supplying milk to the Rewa cooperative dairy company in Fiji. The critical inputs associated with total farm milk production were determined using multiple regression, with analyses being conducted for each of the three identified supplier groups, bulk milk, canned milk and cream. Mean annual milk production per cow averaged 1460 (s.d. = 319), 889 (s.d. = 321) and 800 (s.d. = 451) litres for the bulk milk, canned milk and cream suppliers respectively. Stocking rate averaged 1.37 (s.d. = 1.18) cows per hectare over all farms. Inputs to pasture were universally low and Navua sedge (Cyperus aromaticus) was identified as a major weed. The average amount of supplement fed annually on a grain equivalent basis was 700 (s.d. = 984) kg per cow for bulk milk, 84 (s.d. = 198) kg per cow for canned milk and 146 (s.d. = 542) kg per cow for cream suppliers. The analysis of data from a small group of farms using nitrogen fertiliser indicated that their production levels were higher than the general population. This suggests that there is potential for the Fijian dairy industry to increase milk production through the use of higher inputs to cows and pastures. The regression models relating annual milk production from farms to the two key inputs of number of cows milked and the amount of supplement fed were all significant (p < 0.001). The coefficients of determination for these models ranged from 56.9 to 89.4 percent.
Objective: To observe and compare the effects of multi-patch biopsy under conventional white light imaging endoscopy (C-WLI) and precise targeted biopsy under magnifying narrow-band imaging endoscopy (M-NBI) on the endoscopic submucosal dissection (ESD) of early gastric cancers and intraepithelial neoplasias. Methods: According to the way of selecting biopsy specimens, patients were divided into C-WLI and M-NBI groups, 20 cases. The ESD operations of the 2 groups were compared quantitively. Results: The mean frequency of biopsy in M-NBI group was ($1.00{\pm}0.00$), obviously lower than in the C-WLI group ($4.78{\pm}1.02$) (P<0.01).The average total number of selected biopsy specimens was also fewer ($1.45{\pm}0.12$ and $7.82{\pm}2.22$, respectively, P<0.01). There was no significant difference in the time of determining excision extension, marking time and the time of specimen excision of 2 groups during the ESD (P>0.05), whereas submucosal injection time, mucosal dissection time, stopping bleeding time, wound processing time in the M-NBI group were significantly shorter than in the C-WLI group (P<0.01). Conclusion: Precise targeted biopsy under M-NBI can obviously shorten the time of ESD operation, with small quantity of tissues but high pathological positive rate.

Background: Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. Materials and Methods: The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. Results: The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (p<0.05). There was no significant survival difference between patients with unilateral and bilateral hydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (p<0.05). Conclusions: Hydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.
Background: Radiofrequency ablation (RFA) is the most widely used and studied method internationally for the local treatment of liver tumors. However, the extension of coagulation necrosis in one RFA procedure is limited and incomplete coverage of the damaged area can lead to a high local recurrence rate. Objective: In this study, we compared the effects of different solutions in enhancing hepatic radiofrequency by establishing a rabbit VX2 liver cancer model. We also determined the optimal solution to maximise effects on the extent of RFA-induced coagulation necrosis. Methods: Thirty VX2 tumor rabbits were randomly assigned to five groups: group A, RFA alone; group B, RFA with anhydrous ethanol injection; group C, RFA with 5% hypertonic saline injection; group D, RFA with lidocaine injection; and group E, RFA with a mixed solution. Routine ultrasound examinations and contrast-enhanced ultrasound (CEUS) of the ablation areas were performed after RFA. Then, we measured the major axis and transverse diameter and compared the areas of coagulation necrosis induced by RFA. Results: The mean ablation area range increased in groups B, C and especially E, and the scopes were greater compared with group A. Preoperative application of anhydrous ethanol, hypertonic saline, lidocaine and the mixed solution (groups B, C, D and E, respectively) resulted in larger coagulation necrosis areas than in group A (p<0.05). Among the groups, the coagulation necrosis areas in group E was largest, and the difference was statistically significant compared with other groups (p<0.05). Pathological findings were consistent with imaging results. Conclusions: A mixture of dehydrated alcohol, hypertonic saline and lidocaine injected with RFA increases the extent of coagulation necrosis in the liver with a single application, and the mixed solution is more effective than any other injection alone.

To develop technique for the production of P. tenuipes stromata on a large scale, the infection of P. tenuipes and the growth of stroma were investigated by silkworm (Bombyx mori) variety. Also, studied about biological activites of fruiting body formed on silkworm. Infection rate of the 5th instar larvae of the silkworm with P. tenuipes was the highest in Yangwonjam, followed by Hachojam, Baegokjam and Chilbojam in that order. Also, as the inoculation times was increased, infection rate tended to be raised. The rate of fruiting body formation of the silkworm pupae infected with P. tenuipes was the highest in Baegokjam, followed by Yangwonjam and Chilbojam in the order. But, actually the fruiting body formation of the 5th instar larvae of the silkworm tested was good in Chilbojam, followed by Yangwonjam and Baegokjam in that order in 3 times spraying inoculation. The fruiting bodies of Yangwonjam and Chilbojam infected with P. tenuipes had high amount of Mannitol, but Baegokjam and Hachojam had high concentration of Glucose on a dry weight basis. The mean content of total amino acid in the fruiting bodies of P. tenuipes was 1.03 ${\mu}mole/g$. The distribution rate of amino acid components decreased in the order of Arginine (12.2%)>Glycine (10.5%)> Proline (9.6)>Tyrosine (8.9%)>Serine>Leucine>Threonine. The most abundant amino acid in the fruiting bodies of the Baegokjam, Chilbojam and Hachojam infected with P. tenuipes was arginine, while Yangwonjam was Glycine. The most abundant fatty acid in P.tenuipes was Oleic acid on a dry weight basis. The unsaturated fatty acids such as Oleic acid, Linoleic acid and Linolenic acid accounted for more than 78% of the total fatty acids.
Wet hill seeding (WHS) is one of the more famous labor and money saving methods technology used for rice cultivation. In WHS, rice standing percentage and weedy rice occurrence are the most important factors considered to secure a rice yield. We investigated the optimum seeding date of WHS in the Southern Plain area of South Korea. Weedy rice needed two weeks at $15^{\circ}C$ to show over 80% emergence. Germinated rice seed grown at $20^{\circ}C$ needed over for 10 days to achieve a shoot length over 3 cm. In field cultivation, the mean temperature for ten days after seeding showed a highly positive correlation with rice standing rate, spikelet number per square meter and yield index that favorably compared to machine transplanting. With these data, we suggest that the optimum seeding date of WHS that can secure over 98% of yield index of machine transplanting in Southern part of Korea is May. 21~Jun. 5 in Honam and May. 16~Jun. 5 in Yeongnam area.
Background: Despite the rapid expansion of percutaneous endovascular repair, open surgical repair is still recognized as an option to achieve a cure. We retrospectively analyzed over a 6 year period the surgical outcomes, the complications and the mortality-related factors for patients with abdominal aortic aneurysms. Material and Method: We analyzed 36 patients who underwent surgery for abdominal aortic aneurysms between May 2001 and June 2005, and between April 2007 and November 2009. The indications for surgery were rupture, a maximal aortic diameter > 50 mm, and medically intractable hypertension or pain. Result: The mean patient age was $69.67{\pm}6.97$ years (range: 57 to 84 years). Thirty two patients (88.9%) were males and 4 patients (11.1%) were females. Extension to the iliac artery existed in 28 patients (77.8%). Thirteen patients (36.1%) had ruptured aortic aneurysms. The mean maximal diameter of the aorta was $73.7{\pm}13.3$ mm (60 to 100 mm). Surgery was performed by a midline laparotomy and 10 patients (27.8%) underwent emergency surgery. The mortality rate was 8.3%; the mortality rate for the patients with ruptured aneurysms was 23.1 % and the mortality rate for patients with unruptured aneurysms was 0%. The postoperative complications included wound infection (3 cases), sepsis (2 cases), renal failure (2 cases) and pneumonia (1 case). Unstable vital signs, pre-operative transfusion, ruptured aneurysm, emergency surgery, comorbidity (DM and syncope) and complications (sepsis and renal failure) were the statistically significant mortality-related factors (p < 0.05). Conclusion: Emergency surgery for ruptured aortic aneurysms continues to have high mortality, but the unruptured cases are repaired with relative safety. Even though endovascular aortic repair is the trend for abdominal aortic aneurysms, an elective operation of the unruptured aneurysms could decrease the procedure's morbidity and the inconvenient for repeat evaluation with good surgical results.
The cultivation situation of Korean wheat of 175 farmers in nationwide for two years, 2010/2011 and 2011/2012, was analyzed to obtain basic data for extension cultivated area and enhancing the self-sufficiency ratio of Korean wheat. Compared to the mean temperature and precipitation in the normal year, the mean temperature was lower before the heading stage and higher amount of precipitation after the heading stage in 2010/2011 and higher the mean temperature and lower amount of precipitation after the heading stage in 2011/2012. Average cultivation career and area were 7.7years and 2.4~3.3ha, Keumkang cv. was mainly cultivated for two years and Jokyung and Baekjoong cvs. were increased cultivation areas in southern part of Korea, Gyeongsangnam-do, Jeolllanambuk-do and Kwangju metropolitan city, including in 2011/2012. Most farmers (144) sown wheat seeds from late October to the beginning November with broadcasting method and the other famers were sown using the drill method. Average amount for basal fertilizer was 29.7 kg/10a with complex fertilizer mixed for wheat and barley cultivation, which was higher amount compared to recommended rate of fertilizer amount by rural development administration. Top dressing using nitrogen fertilizer was applied from in the late February to the beginning March. Heading date was the beginning May in 2011 and the late April in 2012, which the mean temperature from regeneration stage to tillering stage in 2011 was higher than that of 2012. Most farmers harvested wheat in mid-June and Pre-harvest sprouting and Fusarium head blight were occurred in 2011 due to the high amount precipitation during grain filling period.
A new naked oat cultivar Daeyang (Avena sativa L.) was developed by Department of Rice and Winter Cereal Crop, NICS, RDA in 2007. It was derived from a cross between 'FLX446-1-84-Q1'. and 'SO92004-B-3-3-5-7'. The FLX446-1-84-Q1, a naked oat cultivar from USA, is early heading and has good seed quality, while the SO92004-B-3-3-5-7, a covered oat breeding line, has a high yield with large grain. Subsequent generations were handled in a bulk method and pedigree selection program, and the SO97013-B-16-4 was selected based on agronomic performance in 2001. The line showed both high yield and good husking rate of seed in the yield trial tested at Suwon from 2002 to 2003, being designated as Gwiri51. The Gwiri51 was subsequently evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup, and Jinju, from 2004 to 2007 and was designated as "Daeyang" and released. Its heading date was May 8 and maturing time was June 14 in a paddy field condition. The new cultivar Daeyang had 97 cm of culm length and 25.2 cm of spike length, 644 spikes per $m^2$, 65 grains per spike, 30.3 g of 1,000-grain weight, and 635 g of test weight. Daeyang showed better winter hardiness than that of the check cultivar 'Sunyang', and similar seed quality to the check cultivar in respect to percent content crude protein and $\beta$-glucan. However, it showed higher husking rate than the check cultivar. Grain yield of Daeyang in the regional yield trial for 4 years were averaged 4.18 MT $ha^{-1}$, which was 20% higher than that of the check cultivar Sunyang. Fall sowing cropping is recommended only in a south area where daily minimum mean temperatures are averaged higher than $-4^{\circ}C$ in January, and should be excluded in mountain area where frost damage is presumable.
A new naked oat cultivar 'Choyang' (Avena sativa L.) was developed by the breeding team at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2007. It was derived from a cross between 'Sikyonggwiri' and 'Gwiri23'. The cultivar, Sikyonggwiri is early heading while the breeding line Gwiri23 has a high yielding potential with large-size grain. Bulk method combined with pedigree selection program was employed in subsequent generations, and the promising line SO96025-B-303-44-2-5 was selected for agronomic performance in 2002. The line showed both high yield and good husking rate of seed in the Yield Trial tested at Suwon in 2003 to 2004, and was subsequently designated as 'Gwiri57'. Gwiri57 was evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup and Jinju from 2005 to 2007 and was released as Choyang. Choyang headed 11 days earlier and matured 5 days earlier than the check cultivar 'Sunyang' in the paddy field condition. The new cultivar Choyang had 97 cm of culm length and 23.4 cm of spike length, 658 spikes per $m^2$, 75 grains per spike, 28.8 g of 1,000-grain weight, and 636 g of test weight. Choyang showed better winter hardiness than that of the check cultivar Sunyang, and similar seed quality to the check cultivar in respect to crude protein (12.9%) and ${\beta}$-glucan content (4.7%). However, it showed higher husking rate than the check cultivar. The grain yield of Choyang in the regional yield trial for 3 consecutive years was averaged $4.67MT\;ha^{-1}$, which was 38% higher than that of the check cultivar Sunyang. Choyang is recommended for the fall sowing cropping only in the southern area where daily minimum mean temperatures are averaged higher than $-4^{\circ}C$ in January, and is not recommended the in mountain area where frost damage is presumable.
