An experiment was conducted to investigate the effects of mineral extract from granite on the performance, ammonia production from the litter, components of blood, Newcastle Disease (ND) titer and intestinal microflora in broiler chickens. Nine hundred sixty one-day-old broiler chickens (Ross) were assigned to five treatments: C; control, Zeolite; control + zeolite 1$\%$, AM10: control + active mineral water $10\%$ adsorbed zeolite $1\%$, AM20; control + active mineral water $20\%$ adsorbed zeolite $1\%$ and AM30; control + active mineral water $30\%$ adsorbed zeolite $1\%$. Each treatment consisted of four replicates with 48 broiler chicks for feeding trial. In order to test the effect of ND vaccine on the components of blood, ND titer and intestinal microflora, a separate group of 48 broiler chicks were assigned to the same 5 treatment as the feeding trial plus one negative control (No ND vaccine). Weight gain, feed intake, feed conversion and mortality were not significantly affected by dietary treatments but AM30 tended to be higher than other treatments in weight gain and feed intake, especially during later period (4 to 5 weeks of age). Ammonia production from the litter of AM30 treatment was significantly (P<0.01) lower than the control. Components of blood and ND titer in serum of broiler chickens were not significantly affected by treatments but MCHC (mean corpuscular hemoglobin concentration) of blood was significantly lower (P<0.05) in Zeolite treatment compared to others. The colony forming unit (CFU) of Clostridium perfringens in the small intestinal content of all zeolite and AM treated groups was significantly (P<0.01) lower than the control while the CFU of Escherichia coli was not significantly affected. The CFU of Lactobacilli in AM30 treatment was significantly (P<0.05) higher than the control. In conclusion, dietary supplement of active mineral water adsorbed to zeolite at $30\%$ level (AM30) tended to improve growth performance of broiler chickens and significantly reduced ammonia production from the litter. It also significantly increased CFU of intestinal Lactobacilli.
This study was carried out to investigate the changes in ovary in repeatedly superovulated rabbits. A total of 57 New Zealand White and Californian, 25 mature virgin and 32 immature does were used in this study. For induction of repeated superovulation, PMSG and HCG were injected at 17-day and 30-day intervals for mature does and 17-day intervals for immature ones. The repeatedly superovulated does at 17-day intervals were induced luteolysis of pseudopregnant corpus luteum with PGF2${\alpha}$ on Day 8 to 9 p.c. The effect of repeated superovulation on reproductive organs was investigated on Day 3 p.c. in mature does and on Day 3 and 6 p.c. in immature ones, respectively. 1. In mature virgin does, the number of ovulation points in the 2nd and 3rd superovulation period averaged 7.0 and 5.0 at 17-day intervals and 13.4 and 6.0 at 30-day intervals, respectively. These numbers were statistically similar to 9.5 ovulation points in the control. However, there were less (p<0.05) ovulation points in those periods compared with 22.1 ovulation points in the 1st superovulation period. 2. In immature does, the number of ovulation points in the 2nd and 3rd superovulation period averaged 5.3 and 2.3, respectively. These numbers were significantly (p<0.05) decreased than 17.1 ovulation points in the 1st periods. The number of ovulation points in the 2nd superovulation period was similar to that in the control, but there was a significant (p<0.05) decrease in the number of ovulation points in the 3rd period as compared to the control. 3. In mature virgin does, the number of visible normal and hemorrhagic follicles (>1.0mm diameter) on day 3 p.c. averaged 19.1 and 8.9 in the 1st superovulation period, respectively. In the 2nd 3rd superovulation period, the number of normal follicles averaged 8.3 and 15.5 at 17-day intervals and 17.8 and 14.5 at 30-day intervals. The number of hemorrhagic follicles in the 2nd and 3rd superovulation period averaged 6.3 and 2.0 at 17-day intervals and 5.2 and 7.8 at 30-day intervals, respectively. There was a slight decrease, although not significant, in the number of normal and hemorrhagic follicles in the 2nd and 3rd period at 17-day intervals compared to that in the 1st period. 4. In immature does, the number of visible normal follicles on day 3 and day 6 p.c. in the 1st superovulation period averaged 27:3 and 26.1, respectively. The follicles on day 3 p.c. tended to increase slightly more than that in the cortrol, but the average number of normal follicles on day 6 p.c. did not differ from that in the control. The number of visible hemorrhagic follicles on day 3 and day 6 p.c. in the 1st of follicles in the 1st superovulation period average 10.2 and 9.9, respectively. There was a slight increase in the number of follicles in the 1st period compared to that in the control. In the 2nd and 3rd superovulation period, the number of normal follicles revealed a slight decrease in the 3rd period, but the number of hemorrhagic follicles was not different between periods. 5. The number of growing follicles with incipient intral formation on day 3 p.c. in mature does of the 1st superovulaton period average 29.7 and the average number of growing follicles in the 3rd period was 26.7 at 17-day intervals and 31.0 at 30-day intervals, respectively. These numbers did not differ from that in the control. In immature does, the number of growing follicles averaged 57.7, 45.0 and 59.3 in the 1st, 2nd and 3rd superovulation period, respectively. There was a slight but not significant decrease in the number of growing follicles in the 3rd period compared to that in the control.
It is important to point out that the percental mortality rate of the multiple pregnancy is almost twice of the single pregnancy due mainly to their prematurity and the mothers of twins will also be suffered from the plural births to nurse and take care of them. We therefore studied the incidence, the sex ratio, the types of deliveries, the complications and the percental mortality rate of the twin deliveries in order to promote the development of our field of maternal and child nursing. We selected our materials from the 112 patients who had been admitted and delivered twins in the department of OB. & Gyn. of the S.N.U. Hospital from Jan. 1962 to Dec. 1969. The abstructed results of this study were as follows. 1. The incidence of twins among 7, 731 births was 1:69 2. The occurrence of twins from elder multigravida was 4 to 6 times higher than younger primigravida mothers under 35 years of age. 3. The generational length of 45.5% of all twins was under 38 weeks and the mean birth weight of 1st and 2nd twins were 2, 354.7gm and 2, 215.8gm respectively. 4. The sex ratio of twins was 99 males and 124 females. 5. Presentation of twins: 59 cases (52.69%) were in both vertex. 37 cases (33.03%) in vertex plus breech. 15 cases (13.39%) in both breech and one case (0.89%) in transverse presentation. 6. For the types of deliveries Spontaneous deliveries were in 90 babies (40.6%) Breech extraction in 60 babies (26.3%) Vacuum used in 33 babies (15.0%) Cesarean section in 33 babies (9.8%) Forceps in 9 babies (4.2%) and others such as version and destructive measures in 9 babies (4.1%) 7. Intervals between the 1st and 2nd delivery were analyzed and 93% of 2nd twins were delivered within minutes after 1st delivery. 8. The main complications of twin deliveries were totemic (45.5%), second was postmarital hemorrhage (19.6%) and third was hydrations (7.1%) 9. The mean percental mortality of 1st and 2nd twins was 12.52% and 16.96% respectively of which main cause of death were their prematurity.

Purpose: To verify the usability of tympanic temperature measurement for adults, a comparison of tympanic and axillary temperatures was done. Method: The study was conducted during October 2008, and participants were 110 female nursing students. Axillary temperatures were taken with glass mercury thermometers for 5, 7 and 10 minutes. Tympanic temperatures were taken with Infrared Thermometer IRT 4520 on both ears, twice at a 5-second interval. The data were analyzed using the SPSS 12.0 program. Results: In the 1st measurement, the mean for right tympanic temperatures ($0.06^{\circ}C$) and for left ($0.03^{\circ}C$) were significantly higher than the 2nd. A comparison of mean temperatures for right and left, showed that the mean for the left side on the 1st measurement was significantly higher ($0.01^{\circ}C$) than the right. Also the temperature on left side in the 2nd measurement was higher ($0.04^{\circ}C$) than the right 2nd, but not significantly higher. The mean temperature for right and left tympanic on 1 st and 2nd measurements were significantly higher than axilla for 5 minutes ($0.58^{\circ}C$), for 7 minutes ($0.52^{\circ}C$), and for 10 minutes ($0.43^{\circ}C$). The tympanic temperature was the most closely correlated with the axillary temperature at 10 minutes. Conclusion: Findings indicate that measurement of tympanic temperature is a useful alternative to axillary temperature taken for 10 minutes.
The effect of die upset and heat treatment on the magnetic properties of mechanically ground $Nd_{16}Fe_{78}B_{6}$ alloys has been studied. Although stripe domain patterns parallel to the compression direction were observed after die upset, it was found that crystallographic c-axes of a specimen were not completely aligned along the compression direction' which resulted in the decrease of Br. The average grain size of a die-upset specimen annealed for 5 hours at $1000^{\circ}C$ was about $20\mu\textrm{m}$, resulting in reduced values of Br and $_{i}H_{c}$. The maximum magnetic properties (Br=7.8 kG and $(_{i}H_{c}=14\;kOe) were obtained from the magnet die-upset at $750^{\circ}C$ using the alloy powder ground for 13 hours.
In order to distinguish Korean cattle (Hanwoo) beef from the imported beef from Australia in Korean markets, DNA markers based on PCR-RFLP from mitochondrial genes and SRY gene were applied. A total of 2,826 beef samples comprising 1,495 Hanwoo and 1,331 foreign cattle breeds were obtained in Korea. An 801 bp fragment of the SRY gene on the bovine Y chromosome, a 343 bp fragment of ND4 gene and a 528 bp fragment of ND5 gene in the bovine mtDNA were amplified by PCR and digested with three restriction enzymes, MseI, HpyCH4III and Tsp509I, respectively. The results showed that Bos taurus (T) type was the majority in Hanwoo by combining three markers (99.5%). However, 78.2% of Bos indicus (I) type was observed in the imported beef samples. These results indicated that three markers used in this study will be used as valuable markers for discriminating imported beef against Hanwoo.

Leaf segments of the potato (Solanum tuberosum L.) genotypes, ND860-2, Norchip, Russet Norkotah, Goldrush, and Norqueen Russet were transformed with the coat protein gene of potato virus Y (PVY). The white-skinned genotypes, ND860-2 and Norchip, were easily transformed and regenerated into shoots, whereas the three russet-skinned genotypes had low frequencies of regeneration. Transformed shoots were generally recovered in four to six weeks. Antibody to PVY coat protein detected a single band of 30 kD in western blots of transgenic plants. Transformed plants had a normal phenotype in the greenhouse and many showed a delayed buildup of PVY following inoculation. Several transgenic lines had negative ELISA readings 85 days after inoculation. Transgenic lines which did not show detectable levels of PVY antigen will be further tested for resistance to PVY.
Purpose: The purpose of this study is to examine the difference of direct nursing activity and patient outcomes as mortality rate, complication rate, readmission rate and length of stay related to graded fee of nursing management for inpatient. Method: The subjects of this study were 44 general hospitals with more than 500 beds. Data totaled to 86,044 claims provided to inpatients in Jan. 2001 requested by an electronic data interchange from a Health Insurance Review Agency. The data was analyzed by SPSS win(ver.10.0) and statistical methods used were frequency, one-way ANOVA, $X^2$-Test and regression. Result: Synthetic judgment through performance index and 95% confidence interval, direct nursing activity showed to provided adequate quality of nursing care on 2nd, 3rd, 4th and 6th nursing degree. Also, patient outcomes showed difference by graded fee of nursing management for inpatient. Mortality rate of 2nd was the lowest with P.I. 67.9, 3rd, 5th, 6th, 4th in order. In case of complication rate, 2nd, 3rd and 4th were lower than other nursing degree. Readmission rate of 4th and 5th was the lowest. Length of stay of 2nd was the shortest with P.I. 88.3, 3rd, 4th, 5th, 4th, 6th in order. Conclusion: The findings from this study showed that, the higher nurse-to-patient ratio, the greater amount of direct nursing care activity for the patient. Also, the more direct nursing activities influenced a lower mortality rate, complication rate and readmission rate, shorter length of stay.
This study was carried out to survey the contents of mineral and heavy metal of the commercial salt and salted-fermented shrimp. Mineral and heavy metal contents of Korean products and imported salts, and their effects on shrimps were analyzed through ICP-AES/MS. K and Mg contents of Korean salts and salted-fermented shrimp were relatively higher than those imported ones, However, no significant differences were found for mineral of commercial salted-fermented shrimps between Korean products and imported ones. Heavy metal contents of commercial salts lower than the maximum permissible limit set by KFDA. As, HB, and Ni were not detected in both commercial and lab-made salted-fermented shrimps. Cd were detected ranges of ND-0.5 ppm (average 0.1ppm) for commercial salted-fermented shrimps. Pb were detected ranges of ND-0.8ppm(average 0.28ppm) for lab-made salted-fermented shrimps.
Low pathogenic avian influenza (LPAI; H9N2) and Newcastle disease (ND) are economically important poultry diseases in Korea. In this study, we investigated pathological features and virus distribution in the lymphoid tissues of chicks experimentally infected with H9N2 and/or ND virus. Six-weeks-old SPF chickens were divided into 4 groups, Control (C), H9N2 (E1), NDV (E2), and H9N2+NDV (E3). E1 group was challenged with 0.1 ml A/Kr/Ck/01310/01 (H9N2) $10^{5.6}$$EID_{50}$ intranasally, E2 group was challenged with 0.5 ml KJW (NDV) $10^{5.0}{\sim}10^{6.0}$$ELD_{50}$ intramuscularly, and E3 group was challenged with H9N2, followed 7 days later by NDV. In histopathological examination, E1 group showed depletion and necrosis in bursa of Fabricius, thymus, cecal tonsil, and spleen, whereas E2 and E3 groups were noted severe lymphocyte depletion and necrosis with destruction of lymphoid organs structures. In TUNEL assay, apoptotic bodies were detected in lymphoid organs of all experimental groups, which was most severe in E3 group. H9N2 and ND viruses were predominantly detected in cecal tonsil of E1, E2, and E3 groups by PCR and immunohistochemistry (ICH). In conclusion, co-infection of H9N2 with NDV caused severe pathologic lesions and apoptosis in lymphoid tissues compared to single infections.
