Purpose: This study was to investigate the effect of the application of cancer pain management guidelines on pain management among patients in Cancer Emergency Room. Methods: This study was a retrospective descriptive study. Before application, data were collected by analyzing the Electronic Medical Record in Cancer Emergency Room in September, 2011, and after application in February, 2012. The subjects of this study consisted of 231 patients (pre-application group 83, post-application group 148), who stayed over 24 hours and complained of pain higher than Numeric Rating Scale score 4. The post-test was conducted after educating the nurses about the application of the pain management guidelines in the Electronic Medical Record. Results: This survey showed that, as the cancer pain management guidelines were applied for cancer patients with above moderate pain, the pain intensity decreased, the number of patients reaching the treatment goal score increased. Furthermore, the estimated time to reach the treatment goal decreased significantly. Conclusion: Pain intensity of the cancer patients was decreased through regular pain assessments by nurses and the medication of analgesics according to the cancer pain management guidelines. Therefore, it is necessary to develop the pain management program and to provide the physicians and nurses with intensive education about the pain management guidelines for systematic and effective pain management.

Background: The effects of the dietary administration of two heat-inactivated whole bacteria from the Vibrionaceae family, singly or combined, on innate immune response of the rainbow trout were studied. The two bacteria (Pdp11 and 51M6), which were obtained from the skin of rainbow trout, showed in vitro characteristics that suggested they could be considered as potential fish probiotics. Methods: The fish were fed four different diets: control (non-supplemented), or diets supplemented with heat-inactivated bacteria at $10^8$ cfu/g Pdp11, $10^8$ cfu/g 51M6 or with $0.5{\times}10^8$ cfu/g Pdp11 plus $0.5{\times}10^8$ cfu/g 51M6 for 4 weeks. Six fish were sampled at weeks 1, 2, 3 and 4, and then the main humoral (natural haemolytic complement activity and serum peroxidase content) and cellular innate immune responses (leucocyte peroxidase content, phagocytosis, respiratory burst and cytotoxicity) were evaluated. Results: The serum peroxidase content and the natural haemolytic complement activity increased with time, reaching the highest values in the third and fourth weeks of feeding, respectively. The phagocytic ability of specimens fed the mixture of the two inactivated bacteria was significantly higher than in the controls after 2 and 3 weeks of treatment. The same activity increased significantly in rainbow trout fed the Pdp11 diet for 2 weeks or the 51M6 diet for 3 weeks. Respiratory burst activity was unaffected by all the experimental diets at all times assayed. Cytotoxic activity had significantly increased after 3 weeks in fish fed the 51M6 diet. Conclusion: Our results demonstrated the usefulness of incorporating inactivated probiotic bacteria into fish diets.

자동배선 시스템의 배선영역 모델링 방법은 그리드와 논 그리드 방식을 사용하고 있다. 그리드 방식은 PCB상에 전기적, 물리적 요소들이 적다 할지라도 보드와 그리드의 크기에 제약을 받기 때문에 자동배선 속도를 감소시키는 단점을 가지고 있다. 따라서 메모리 용량을 증가 시키게 된다. 논 그리드 방식(Shape based type)은 영역처리 방식을 사용하며, 배선영역에서 그리드 방식보다 44.2% 메모리 감소효과가 있다. 따라서 Via 수는 55.5%의 감소 효곽가 있으며, 총 배선 시간도 기존 PCB시스템보다 83.3% 향상되었다. 본 논문에서는 단일 원점에서 여러 목적지에 가장 빠르게 도달 할 수 있고 최단 경로 문제를 해결하는 auction 알고리즘을 적용한 Shape based 방식에 의하여 메모리 낭비 없이 빠른 속도로 자동 배선할 수 있는 PCB 자동 배선 시스템을 개발하였다. 또한 본 시스템은 IBM Pentium 컴퓨터 Windows 환경에서 Visual C++언어로 개발하였으며 다른 PC 와도 호환성을 가질수 있도록 개발 하였다.

This study was performed to investigate factors affecting sensitivity and preference for salty tastes of Korean adult females. Sensitivity and preference for salty tastes were determined as detection threshold concentration of NaCl solution and the optimally-preferred NaCl concentration of the bean sprout soup, respectively. A self-administered questionnaire was used to obtain the information regarding general characteristics, self diagnosis of stress, health-related lifestyle practices, dietary habits and food preferences. Dietary intake using 24-hours recall and blood pressure were measured. Salty taste detection thresholds and optimally-preferred NaCl concentrations were 0.0197% and 0.357%, respectively. There was a significant positive correlation between the optimally-preferred salt concentration and age, despite no significant correlation between either sensitivity or preference for salty taste and sodium intake, which was 3,605mg/day. Those who had bread or cereal with milk as breakfast instead of a traditional Korean meal and those who preferred jjigae to soup had significantly higher NaCl preferences for bean sprout soup. Going to bed after midnight and skipping meals (${\geq}3/week$) decreased salty taste sensitivity without reaching statistical significance. Self awareness of one's own health, recent weight changes, family history of hypertension, sleep quality, getting-up time, rate of eating and other food preferences did not affect either perception. Stress level, TV watching, BMI and sodium intake did not have significant correlation to sensitivity or preference. Further research including a large number of well-controlled subjects and more accurate measurement of sodium intake should be directed to find other factors affecting salt preference and sensitivity in order to decrease Na intake and related diseases.

Mycoplasma pneumoniae pneumonia (MPP) is one of the most common forms of community-acquired pneumonia in children and adolescents. Outbreaks of MPP occur in 3- to 7-year cycles worldwide; recent epidemics in Korea occurred in 2006-2007, 2011, and 2015-2016. Although MPP is known to be a mild, self-limiting disease with a good response to macrolides, it can also progress into a severe and fulminant disease. Notably, since 2000, the prevalence of macrolide-resistant MPP has rapidly increased, especially in Asian countries, recently reaching up to 80%-90%. Macrolide-resistant Mycoplasma pneumoniae (MRMP) harbors a point mutation in domain V of 23S rRNA with substitutions mainly detected at positions 2063 and 2064 of the sequence. The excessive use of macrolides may contribute to these mutations. MRMP can lead to clinically refractory pneumonia, showing no clinical or radiological response to macrolides, and can progress to severe and complicated pneumonia. Refractory MPP is characterized by an excessive immune response against the pathogen as well as direct injury caused by an increasing bacterial load. A change of antibiotics is recommended to reduce the bacterial load. Tetracyclines or quinolones can be alternatives for treating MRMP. Otherwise, corticosteroid or intravenous immunoglobulin can be added to the treatment regimen as immunomodulators to downregulate an excessive host immune reaction and alleviate immune-mediated pulmonary injury. However, the exact starting time point, dose, or duration of immunomodulators has not been established. This review focuses on the mechanism of resistance acquisition and treatment options for MRMP pneumonia.

Purpose: The present study was designed to investigate the effect of trunk control training on the labile surface on relative impulse and balance in stroke patients. Methods: A total of 21 participants were assigned to an experimental group (n=11) or a control group (n=10). In addition to conventional therapy, the experimental group received trunk control training on the swiss ball; 20 minutes, 4 times a week, for 8 weeks. Balance ability was evaluated by FRT (functional reaching test) and TUG (time up and go). In addition relative impulse in 6 areas of the foot (hallux, 1st metatarsal head, 2~3 metatasal head, 4~5 metatasal head, mid foot and heel) were measured using the F-scan system to evaluate locomotion ability during gait. Results: Significant differences in the relative impulse were observed in the areas of the 2~3 metatasal head during gait after exercise in both the control group and experimental group (p<0.05). Also, a significant increase was seen in the hallux after exercise in the experimental group (p<0.05), but no such significant increase was seen in the control group (p>0.05). Significant differences were observed in FRT and TUG in the experimental group but no such significant increase was observed in the control group (p>0.05). Conclusion: These results suggest that trunk control training on labile surface improves the balance in stroke patients and has a positive effect on locomotion ability.

The word 'lace' comes from the Latin, lacium, meaning a knot. There are two broad categories of lace: needlepoint lace and bobbin lace. Lace has enjoyed a multitude of uses, embellishing both liturgical and domestic objects. It has also played a major role in the history of western fashion, adorning the apparel of men as well as women. Lace lappets and cap crowns, cravat ends and veils were made for those who could afford them. Before the end of the sixteen century, more complex techniques were employed. The baroque period, needlepoint lace evolved from the early simple geometric patterns of punto in aria Which enhanced ruffs, to deeply scalloped designs, often referred to as collar lace, and thence to the bold and magnificent relief effects of Venetian gros point. Through the seventeenth century is noted for the infinite variety of its cravat, collar and kerchief, most of them lace trimmed and all artfully contrived for the wearer. The type of sleeve in women's dress reaching just below the elbow, ending in ruffles of lace which was called engageantes. Sometimes the ends of a fichu or headdress decorated of lace. In the nineteenth century, empress Eugenie's love of lace resulted in a marked increase in the use of that lovely, delicate fabrication. It was lavished upon sleeves, hats, capes, and handkerchieves. Entire flounces, parasols, jackets, and shawls of lace were created by skilled lace makers of Europe. By the time this magnificent piece was created, most lace was being produced by machine. Today, the tradition of handmade lace continues, but glorious examples are no longer made. However, the techniques have been taken up and revitalized within the fiber art movement.

Seedling establishment of soybean [Glycine max (L.) Merr.] is a critical factor in production system and cultural practices. The objective of this study was to identify the components of soybean seedling developments encompassing planting dates and cultivars that respond to emergence, early growth stage and dry matter accumulation. Three soybean cultivars, Hwangkeumkong, Shinpaldalkong 2, and Pungsannamulkong, were planted at Baegsan silty loam soil. Planting date was May 13, June 3, and June 24 in 2001. Sprinkler irrigation was accompanied with 30mm after seeding for three planting dates. Soybean seedlings were sampled at the growth stages from VE to V5. Days to emergence of soybean seedlings were taken 8 at May 13 and 5 at June 24 plantings. Emergence percentage was over 90 at three planting dates. May 13 planting took 33 days and June 24 planting was 25 days for reaching V5 growth stage. Cotyledon number was decreased after V2. Significant cultivar difference was found in cotyledon dry weight until V2 which differed in seed dry weights at the planting times. Leaf and total dry weights of soybean seedlings were not differed from V1 to V3 among planting dates and cultivars. Leaf water contents were generally ranged 78 to 85%. Branch was appeared from V4. Leaf/stem ratio among cultivars was similar at five growth stages and gradually increased from 2.1 at V1 to 2.8 at V5. The results based on this experiment indicated that seedling establishment of soybean was continued from VE to V3 growth stages affecting mainly by planting date and soil moisture.
