  • 본 연구는 간척지 토양 염농도별(저염; 0.1-0.2%, 중염; 0.3~0.4%)로 분얼기 관개수 염수처리 농도에 따른 벼 생육 및 수량성을 검토하고자 시험한 결과를 요약하면 다음과 같다. 가. 토양 및 관개수 염농도가 높을수록 초장은 짧았고 주당경수도 적었으며, 특히 중염 토양에서 관개수 염농도 0.3% 이상에서는 모두 고사되었다. 나. 토양 및 관개수 염농도가 높을수록 출수는 지연되었으며, 토양 염농도간에는 중염 토양에서 저염 토양보다 2-5일 정도 늦었다. 다. 간장은 관개수 염농도가 높을수록 짧았고 중염 토양이 저염 토양보다 짧았으며. 수장도 같은 경향이었다. 라. 저염토양에서는 관개수 염농도가 높을수록 $\textrm{m}^2$ 당립수가 적고 등숙비율이 낮아, 쌀수량은 민물 관개 수량에 비해 관개수 0.l%는 92%, 0.3%는 84%, 0.5%는 56%, 0.7%는 36% 수준이었다. 중염토양의 쌀수량은 저염토양 민물 관개 수량에 비해 민물 관개는 62%, 0.1% 관개수에서는 30% 수준이었다. 따라서 관개수 염농도가 저염 토양은 0.7%, 중염 토양은 0.3%까지 생육은 가능하나 수량 감소가 커서, 소득지수로 볼때 간척지 쌀 생산 한계 관개수 염농도는 저염 토양은 0.5% 이하에서, 중염 토양은 민물 관개수에서 가능하였다.

  • The present study was performed to evaluate the effect of tetracycline - HCl on the change of implant surface microstructure according to application time. Implants with pure titanium machined surface and titanium plasma-sprayed surface were utilized. Implant surface was rubbed with 50mg/ml tetracycline - HCl solution for 1 min., $1\frac{1}{2}\;min$., 2 min., $2\frac{1}{2}\;min$. and 3min. respectively in the test group and with saline for 1 min. in the control group. Then, the specimens were processed for scanning electron microscopic observation. The following results were obtained. 1. Pure titanium machined surfaces conditioned with saline for 1 min., showed a few shallow grooves and ridges and were less irregular. 2. Pure titanium machined surfaces conditioned with 50mg/ml tetracycline - HCl solution showed more irregular and corrosive surfaces compared to the control group irrespective of the application time of tetracycline - HCl solution. 3. Titanium plasma-sprayed surfaces conditioned with saline for 1 min., were deposited with round amorphous particles and showed round or irregular pores that can be connected to each other. 4. The irregularity of titanium plasma-sprayed surfaces conditioned with 50mg/ml tetracycline - HCl solution was lessened and the flattened areas were wider relative to the application time of tetracycline - HCl solution. 5. Titanium plasma-sprayed surfaces conditioned with tetracycline - HCl solution for 1 min. and $1\frac{1}{2}\;min$. were very similar to that of the control group, but the surfaces conditioned for 2 min., $2\frac{1}{2}\; min$. and 3 min. were changed. In conclusion, pure titanium machined surfaces were changed irrespective of the application time of tetracycline - HCl solution. And titanium plasma-sprayed surfaces conditioned with tetracycline - HCl solution began to be changed from $1\frac{1}{2}\;min$. This results will be applicable to the regenerative procedures for peri-implantitis treatment.

  • Background and Objective: Rectal washout with saline solution may theoretically prevent anastomotic recurrence in patients with resectable rectal cancer, although exact clinical effects have not yet been determined. In order to derive a more precise estimation of the relationship, the present meta-analysis was performed. Method: Relevant studies were identified by a search of Medline, Embase and Google Website with no restrictions to September 1, 2013, and included in the systematic review and meta-analysis. Results: 5 trials (642 participants) were included to assess the association between rectal washout with saline solution and anastomotic recurrence. The rate of anastomotic recurrence (AR) was 6.23% (40/642), with the pooled OR derived from the five studies being 0.32 (95 % CI=0.15-0.70, P=0.004). The pooled OR derived from the TME and radical resection subgroups were 0.72 (95%CI=0.16-3.12, P=0.66) and 0.51 (95%CI=0.13-1.96, P=0.32), respectively. Conclusion: Results from this analysis show that intra-operative rectal washout with mere saline solution largely reduces the risk of anastomotic recurrences in patients with resectable rectal cancer.

  • The effect of ultra-sonication on quality characteristics and flavor of baked eggs was studied. One hundred and twenty eggs were cooked and assigned to six treatments groups (n=20 each) that were then soaked in saline solution at various concentrations (5, 10 and 18%) with/or without further ultra-sonication treatment at 35 kHz for 1 h. The pH values were lower in the ultra-sonicated samples in comparison with the non-ultra-sonicated samples (p<0.05). The values for texture traits were higher in the samples soaked in 10% saline solution with ultra-sonication in comparison with other remaining treatments or control (p<0.05). The sodium content in samples soaked in 10% saline solution with ultra-sonication was similar to that of the ones soaked in 18% saline solution without ultra-sonication. The higher flavor scores were also given for the ultra-sonicated samples in comparison with the control or non-ultra-sonicated ones. These results suggest that the application of ultra-sonication may produce a faster sodium penetration into baked eggs, simultaneously improves some textural traits (e.g., hardness) as well as flavor of the products.

  • The inactivating efficiency of alternating high-voltage pulsed (AHVP) current was investigated in brine (20 w/v% NaCl) and saline (0.9 w/v% NaCl) inoculated with $1\times10^7$ cells/ml of Listeria monocytogenes. AHVP current at 12 V with 1 pulse completely inactivated L. monocytogenes in brine within 3 ms, while the bacteria in saline were fully inactivated by 10-pulsed electric treatment at 12 V within the same time. Electron microscopic observation demonstrated substantial structural damage of electrically treated L. monocytogenes in brine. These results suggest that AHVP treatment would be effective for the rapid and complete inactivation of L. monocytogenes in brine or saline solution.

  • Purpose: This study was designed to investigate whether there were differences among three oral care protocols on participants' oral health status (oral status, dry mouth, halitosis, saliva pH, microorganism growth in oral cavity) and tooth stain. The three protocols were: 1) oral solution of 4% normal saline, 2) 0.1% Chlorhexidine and 3) Tantum. Methods: A nonequivalent control group pretest-posttest design was utilized. A total of 55 elderly patients residing at long-term care facilities(19 in the 4% normal saline group, 17 in the 0.1% Chlorhexidine group, 19 in the Tantum group) received oral care daily for four weeks. Data were analyzed using SPSS/WIN 22.0 program. Results: The halitosis (${\chi}^2=10.71$, p=.005) and saliva pH (${\chi}^2=6.84$, p=.033) scores were significantly improved after the oral care with 4% normal saline. Conclusion: These findings indicate that if elderly patients in long-term care facilities have complaint of the discomfort of using Chlorhexidine or Tantum, 4% normal saline is as effective at the other two. This can also be cost effective as there were no differences among the protocols in oral status, dry mouth, tooth stain or microorganism growth in oral cavity.

  • The purpose of this study was to evaluate the cleansing effect of Glyoxide on the dentinal walls of the root canal. Fourty teeth were divided into four groups and the canals in each group were individually enlarged with K-file by step-back technic and irrigated with one of four irrigants. The four used irrigants were Glyoxide (Marion lab. U.S.A.) in combination with 3.5% sodium hypochlorite, 3.5% sodium hypochlorite, 3.5% sodium hypochlorite in combination with 3% hydrogen peroxide and normal saline solution. All the irrigants were used in conjunction with instrumentation as they would be during clinical conditions. After final irrigation, the canals were dried with paper points and the teeth were split longitudinally. The cleaness of canal walls according to the size and the level of canals were evaluated under steroscope by t analysed statistically The results were as follows. 1. The use of 3.5% sodium hyphochlorite in combination with 3.0% hydrogen peroxide revealed the most clean canal surface regardless of the size of canal at apical third of root canal (p < 0.05). 2. Glyoxide in combination with 3.5% sodium hyphchlorite showed no significant difference in cleaning effect of canal surface compared with 3.5% sodium hypochlorite and normal saline solution at the apical third of narrow canal. 3. Glyoxide in combination with 3.5% sodium hypochlorite revealed no significant difference in debridement of canal walls compared with 3.5% sodium hypochlorite in combination with 3% hydrogen peroxide and saline solution at the middle third of narrow and large canals.

  • Isolation and identification, prevalence and density of Setaria microfilariae(mf) were investigated in the blood of 406 cattle slaughtered at the abatoirs in Yungnam province from February 1999 to March 2000. Nine ml of blood from the jugular vein was collected in a test tube including EDTA respectively. The blood was mixed(10 : 1) with 0.2% Saponin in saline solution. This mixture was diluted again(1 : 10) with saline solution and stirred. This diluted mixture was filtered using Millipore membrane filter with a pore size of $3.0{\mu}m$. Mf were recovered from the membrane in saline solution. Mf isolated were identified as Setaria digitata on the basis of morphologic characteristics. Infection rate of the mf of total 406 cattle was revealed as 6.40%. Seasonal prevalences of the mf were presented 9.46%(7/74) in Autumn, 7.05%(11/156) in Summer, 4.65%(4/86) in Winter and 4.44%(4/90) in Spring respectively. Average density of the mf of every 9ml blood in 26 positive cattle was revealed as 170(2-641) worms. Seasonal densities of the mf of 9ml blood were presented average 361(160-641) worms in Autumn, 205(16-620) worms in Summer, 108(6-204) worms in Spring, 6(2-11) worms in Winter respectively.

  • Purpose: The purpose of this study was to examine the effect of nebulizer therapy with normal saline on thirst and sore throat among postoperative patients. Methods: A quasi-experimental nonequivalent control group, pretest-posttest design was used with 50 participants. The experimental group received nebulizer therapy with normal saline every two hours for 10 minutes three times and wet gauze (n= 25), and the control group received only wet gauze (n= 25). Data were collected using the Numeral Rating Scale for Thirst and Sore Throat. Measurements were calculated before applying nebulizer therapy and total five times for 12 hours after treatment. Data were analyzed using the repeated measured ANOVA. Results: Thirst for the experimental group using the nebulizer therapy with normal saline improved more than for the control group (F= 3.06, p= .043). Sore throat was not significantly different between the two groups (F= 0.63, p= .565). Conclusion: Study results indicate that using nebulizer therapy with normal saline can reduced thirst for postoperative patients. So nurses can apply nebulizer therapy with normal saline to reduce thirst and to improve comfort for postoperative patients.
