Productivity, nutrient contents, in vitro gas production and in sacco degradability of different fractions and whole OPF were determined to assess the feeding value of OPF as a ruminant feed. An in vivo digestibility trial was also carried out using goat. Freshly harvested OPF was randomly collected, partitioned and weighed. An OPF from 21 years older palm weighed 13.4 kg and the annual fresh matter yield of petiole, leaflet and midrib was 46.5, 11.8 and 3.4 ton/ha, respectively. Leaflet contained 439, 926, 698, 501, 168, 196, 748 and 52 (g/kg) of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose (CE), hemicellulose (HC), total carbohydrate (TC) and non fiber carbohydrate (NFC), respectively. Petiole contained lower (p<0.01) DM, CP and EE contents than leaflet. Organic matter, CE and TC contents were higher (p<0.01) in petiole compared to leaflet. Silica and lignin contents were highest (p<0.01) in midrib followed by leaflet, whole OPF and least in petiole. The Ca, P, Na, K and Mg contents (g/100 g DM) of leaflet were 0.529, 0.182, 0.039, 0.876, and 0.168, respectively. In vitro DM digestibility (g/100 g) at 48 h of leaflet, petiole and midrib was 32.7, 38.7 and 30.2, respectively. The in sacco DM degradation (g/100 g) at 48 h of leaflet was higher than that of whole OPF, petiole and midrib. The in vivo digestibility of DM, OM, CP and ADF of whole OPF was 52, 56, 43 and 26%, respectively. It can be concluded that leaflet is the most nutritious fraction of OPF and midrib is the least. The nutrient content and digestibility of the whole OPF showed that OPF could be an alternative roughage source for ruminant diets.

In this study, the leaflet motion of a mechanical heart valve and the characteristics of two-dimensional transient blood flow in an elastic blood vessel have been numerically investigated by using fluid-structure interaction method. Here, blood has been assumed as a Newtonian, incompressible fluid. Pressure profiles have been used as boundary conditions at the ventricle and the aorta. As a result, closing motion of the leaflet is faster than opening one. While opening angles of leaflet grow up, vortex is detected at the sinus and backward of the leaflets. When the leaflet is fully closed, vortex is detected at the ventricle and at that moment maximum displacement of the elastic blood vessel is observed in the vicinity of the sinus region. Maximum displacement is caused in association with the blood flow that is oriented toward the elastic blood vessel.

The comprehensive aortic root and valve reconstruction (CARVAR) technique comprises two main procedures, which are aortic root reduction using prosthetic rings and neo-leaflet reconstruction using a pericardial patch. Although concerns about durability of the pericardial neo-leaflet have been raised in the CARVAR technique, complications related to leaflet reconstruction have not been reported to date. The present report describes two cases of complications associated with leaflet reconstruction. After resecting the reconstructed leaflets, aortic valve replacement was performed in the patients. Careful and close follow-up is required for patients who had undergone CARVAR surgery, and aortic valve surgery should be performed in a timely manner if needed.

Fracture of prosthetic valve leaflets in the absence of traumatic injury is very rare. Leaflet fracture can cause acute pulmonary edema and cardiogenic shock and is potentially life-threatening, requiring emergency surgery. Thus, a leaflet fracture must be diagnosed quickly and accurately. We present the case of a 46-year-old man with CarboMedics prosthetic aortic and mitral valve replacements implanted 24 years previously. The patient presented at our emergency department with abrupt dyspnea and fever. We diagnosed severe mitral valve regurgitation with anterior leaflet fracture. The patient underwent venoarterial extracorporeal membrane oxygenation and delayed mitral valve replacement. The foreign body was removed step by step because the diagnosis was missed. Two pieces of broken leaflets were found in the left common iliac artery and left external iliac artery. The patient was treated successfully and remains asymptomatic 1 year following surgery.

Objective: This study aimed to explore the readability and comprehensibility of the drug information on a patient leaflet for the senior by employing performance-based user-testing. Methods: We included 36 elderly (65 years old or older) as the senior group (intervention group) and 36 adults (40~59 years old) as the adult group (control). We developed a questionnaire to test if participants could access to drug information. After completing a questionnaire, the participant was interviewed about their understanding over the patient leaflet. We performed t-test, ${\chi}^2$-test or Fisher's exact test to examine differences between two groups in primary outcomes. Results: The senior were less likely able to find information (78%) than the adult (91%); they were much less likely able to understand information (42%) than the adult (69%). While we found differences between the ability of finding and understanding drug information in both groups, the senior group had greater difficulties in understanding all kinds of drug information. They had significant difficulties to remember information after reading the patient leaflet and frequently failed to find proper information even though they were allowed to access freely to the leaflet during interviewing. Conclusion: To secure safe and effective use of drugs for the senior, it is necessary to develop drug leaflets for the senior.

Background: To assess the effect of an information leaflet on the level of Chinese youth's knowledge about hepatitis B and hepatocellular carcinoma (HCC), the most common type of primary liver cancer (PLC). Materials and Methods: A total of 500 students, from two universities in the Chaoshan area of China, were randomly divided into an intervention group of 280 participants and a control group of 220. Baseline knowledge of HCC and hepatitis B was evaluated by questionnaire interview. Subsequently, only the intervention group was given an information leaflet of HCC and hepatitis B. Three months later, the two groups were contacted for a second interview. Changes in knowledge from baseline of HCC and hepatitis B were compared between the two groups. Results: There was no statistically significant difference in mean PRE-questionnaire scores between the intervention and control groups. However, the mean POST-questionnaire score was significantly higher in the intervention group after the intervention. The leaflet had the greatest effect on the participants' questionnaire score, and raised their level of knowledge about HCC and hepatitis B. Conclusions: The information leaflet intervention is significantly effective in improving the knowledge of HCC and hepatitis B among the youth.

The Hydrodynamic performance of the trileaflet polymer prosthetic valves depends on the design of the leaflet and the physical properties of the leaflet membrane. In order to study the effect of leaflet membrane elasticity on the hemodynamic performance of trileaflet prosthetic valve, leaflet membranes are manufactured using two different polymers - Biospan and Tecoflex SG-93A. The hemodynamic performance parameters are measured under steady and physiological pulsatile flow, and compared with monoleaflet polymer valve(floating valve) and bileaflet mechanical valve(St. Jude Medical valve). Well designed trileaflet valve shows the lowest mean pressure drop among the tested valves. The trileaflet valves with Biospan membrane show lower pressure drop and back low comparing to those with Tecoflex membrane. More elastic membrane may provide wide opening area during systole and close membrane ree edge contact during diastole. Durability of trileaflet valves are also tested in vitro. Trileaflet valves with non-uniform membrane thickness ail within 17 days because of stress concentration. Trileaflet polymer valves with uniform membrane thickness perform well over 55 days without failure.

Twin-bud seedlings and four-leaflet seedlings of ginseng were found and transplanted to field and their growth characteristics were investigated. 1. Appearance frequencies of twin-bud and four-leaflet seedlings were 0.3 and 0.4 percent, respectively, in common nursery bed: and were 6.6 and 28.4 percent, respectively, in polystem line. 2. Generally, the growth of twin.bud and four-leaflet seedlings were better than those of common seedlings both in aerial part and in root. Root weights of both type seedlings exceeded the common ones by 66 and 38 percent, respectively. 3. When they became two-year-old plants, leafiet number of common plant was 11.6, and those of twin-bud and four-leaflet-seedling plants were 18.1 and 13.8, respectively. There were no inflorescence in twin-bud-seedling plant, but the ratios of in florescent Plant in four-leaflet.seedling and common plant were 44.0 and 12.5 percent, respectively. 4. In two-year-old plant, root weights of twin-bud and four-leaflet-seedling plants were heavier than those of common ones by 27 and 20 percent, respectively.

Purpose: The purpose of this study was to develop an informational leaflet on emergency care and to explore effects of facilitative nurse-patient interaction behavior using an informational leaflet on patient satisfaction with nurse-patient interaction behavior, patient anxiety, and patient satisfaction with use of emergency care. Methods: This study was a quasi-experimental study that applied a nonequivalent control-group posttest-only design. The participants were 81 patients who visited the emergency department of a hospital in Korea; the experimental group (n=40) received facilitative nurse-patient interaction behavior using an informational leaflet, and the control group (n=41) received care under routine protocols without an information leaflet. The effects of the two groups were analyzed using an independent t-test with SPSS computer program. Results: Patient satisfaction with nurse-patient interaction behavior and use of emergency care in the experimental group were significantly higher than in the control group. Patient anxiety related to using emergency care in the experimental group was significantly lower than the control group. Conclusion: Therefore, facilitative nurse-patient interaction behavior using an informational leaflet to the patient may be useful interventions that are easily implemented by nurses in emergency settings.

This study was carried out to develope the equations for estimating the areas of leaflet, leaf, and total leaf for 1, 2, 3, 4, 5, and 6 years old ginseng, Panax ginseng, grown in field. The highest correlation coefficient was found between leaflet area and product of leaflet length and width(LW) in all leaflets although leaflet shape varied somewhat according to the position and plant age. It was possible to estimate area of the leaf, and total leaf by one central leaflet in a compound leaf. The equations for estimating the leafet, leaf areas of 1 year differ to those of over 2 years old plant, but there was no difference among those of 2, 3, 4, 5, and 6 years. The equations for 1 year old are A =0.64 LW, A' =A/0.38, and for 2, 3, 4, 5, and 6 years old, A =0.60 LW, A' =A/0.32, A" =A' x number of leaves of central leaflet(A), leaf(A') and total leaf areas(A"), respectively. The estimation of leaflet, leaf, total leaf areas of ginseng plant grown under 20% light-transmittance rate was possible by using the equations mentioned.
