Purpose : The purpose of this research was to determine the effects of nap between therapeutic interventions on motor learning in patients with stroke. Method : Thirty stroke patients with hemiplegia were participated in this study. After the screening by questionnaire about nap time, the patients were assigned to nap or non-nap group. Therapeutic interventions for 30 min were provided two times per day for 5 days per week and the serial reaction time tasks were conducted 2 times before and after a nap per day for 3 days per week. Between the therapeutic interventions, a nap for 60~120 minutes was allowed to the nap group while non-nap group was not. Intervention programs were carried out during the total 15-day. Result : Compared with the non-nap group, the reaction-precision level of nap group was increased (p<.05) for the non-affected upper extremity in the serial reaction time tasks. Conclusion : This study demonstrated that nap between therapeutic interventions has positive effects on motor learning in patients with stroke.

It was previously shown that AtNAP1 is a plastidic SufB protein involved in Fe-S cluster assembly in Arabidopsis. In this study, we investigated the effects of depleting SufB protein from plant cells using virus-induced gene silencing (VIGS). VIGS of NbNAP1 encoding a Nicotiana benthamiana homolog of AtNAP1 resulted in a leaf yellowing phenotype. NbNAP1 was expressed ubiquitously in plant tissues with the highest level in roots. A GFP fusion protein of the N-terminal region (M1-V103) of NbNAP1 was targeted to chloroplasts. Depletion of NbNAP1 resulted in reduced numbers of chloroplasts of reduced size. Mitochondria also seemed to be affected. Despite the reduced number and size of the chloroplasts in the NbNAP1 VIGS lines, the expression of many nuclear genes encoding chloroplast-targeted proteins and chlorophyll biosynthesis genes remained unchanged.

In order to elucidate the effect of phenobarbital (PB) on the nonlinear pharmacokinetic behavior of naproxen (NAP), we compared the dose dependent hepatic intrinsic clearance, biliary excretion and protein binding of NAP in control rats to those in the PB-pretreated rats which were intraperitoneally pretreated with PB sodium (75 mg/kg) once a day for four days. NAP was injected via femoral (1.5 mg/kg) and portal(0.25, 0.5, 1.5, 15 and 30 mg/kg) vein to the control and PB-pretreated rats, respectively. And also, we measured the plasma free fraction of NAP with the equilibrium dialysis method and the biliary excreted total amounts of NAP in both rats. Plasma free fraction of NAP was decreased in lower concentration than $150\;{\mu}g/ml$ of NAP due to PB pretreatment. In higher concentration, however, plasma free fraction was increased. These in vitro results suggest that the total protein concentration was increased but the total binding capacity of NAP to protein was decreased by PB-pretreatment. The total plasma clearance and the hepatic intrinsic clearance of NAP had similar values in both groups, respectively. And, both clearances of NAP were significantly increased by PB-pretreatment. Even though the plasma free fractions of NAP in both groups were constantly remained within the concentration range according to the increase of administration dose, the hepatic intrinsic clearances of NAP were significantly increased in both groups with the increased dose. And, the biliary excreted total amounts of NAP were significantly increased by PB-pretreatment at the lower dose, but decreased at the higher dose. These in vivo results suggest that NAP represents the uncommon nonlinear pharmacokinetic behavior that the hepatic intrinsic clearance was enhanced with the increased dose, and that PB enhances further the hepatic intrinsic clearance of NAP with the increased dose due to its enzyme induction effect.

The anterolateral thigh flap(ALT flap) was originally described in 1984 as a septocutaneous nap based on the descending branch of the lateral circumflex artery. This nap has some significant advantages for reconstruction of the head and neck. It can be raised as a subcutaneous flap, a fasciocutaneous nap, or a myocutaneous nap and can resurface large defects in the head and neck. In addition, it has a large and long vascular pedicle, and because of the distance of the donor site from the head and neck, it can easily be harvested with a two-team approach. However, the number and locations of cutaneous perforators vary individually, and thus, it is not widely used because nap elevation is often complicated and time-consuming owing to unexpected anatomical variations. The purposes of this study are to clarify the vascular anatomy and to assess the suitability of anterolateral thigh nap for oral cavity reconstruction in Koreans. In addition, we used anterolateral thigh free nap for oral cavity reconstruction in 20 oral cancer patients from 2006 to 2011. Through our clinical experience, we discuss a series of practical "pearls and pitfalls". Our experience has not only given us new flap choice using anterolateral thigh nap in oral cavity reconstruction, but also given us a new possibility on the applicability of chimeric naps.

This paper describes an overall Noise Assurance Plan(NAP) in the project for developing a new rolling stock. In this paper, the procedure for implementing noise control activities for each development stage on the basis of the NAP is also described. The NAP was developed by KITECH(Korea Institute of Industrial Technology) and ODS(${\Phi}$degaard ＆ Danneskiold-Samsoe in DENMARK). Generally, the main objective of NAP is that noise assurance plan applies to the establishment of organization and personnel's roles and responsibilities, set-up of overall procedure and internal audit program. Here, a few comments are made to the deviations of the actual procedure(G7 Project) relative to the suggested NAP presented. The major difference between the suggested NAP and the actual procedure was the late involvement of the noise consultant resulting in suggestions for design improvements could not be implemented due to the advanced stage of the design. Similarly, the important task of preparing sub-supplier specifications was performed. The proposed NAP will be an efficient tool for noise management in the R＆D project for new rolling stock. Specially, in case that several companies and institutes are involoved in the R＆D team

H. pylori is known to cause severe gastric diseases, including peptic ulcers and gastric cancers, and a link has also been suggested with iron-deficiency anemia (IDA). However, little is known about the pathogenesis of H. pylori-associated IDA. In the present study, to determine whether H. pylori strains are correlated with the prevalence of IDA, we analyzed and compared the sequences of the napA genes encoding a bacterioferritin-like protein in H. pylori strains. A total of 20 H. pylori strains were isolated from antral biopsies of patients with and without IDA, and the napA genes amplified from the genomic DNA were sequenced. A comparison of the deduced amino acid sequences for NapA revealed two sites with major variations. At residue 70, five out of the 12 non-IDA strains ($41.7\%$) contained serine, while only one of the 8 IDA strains ($12.5\%$) contained serine, indicating a significantly higher frequency of serine in the non-IDA strains. In addition, the NapA proteins from all 17 Western strains available on Web sites were found to contain serine residues at this position. Meanwhile, the other major variation was located at residue 73, where all eight IDA strains ($100\%$) contained leucine, while this was only true for eight of the 12 non-IDA strains ($66.7\%$). Therefore, these results indicated that the strains within each group were more genetically related to each other than to strains in the other group. When the expression level of the napA genes in the H. pylori strains was measured using RT-PCR, no significant difference was observed between the two groups, suggesting a similar intensity for the inflammatory responses induced by the NapA protein among the strains. Consequently, when taken together, the present data suggest that the occurrence of H. pylori-associated IDA may be partly determined by the infecting H. pylori strain, and the non-IDA strains are more closely related to Western strains than the IDA strains.

N crassa mutant strain nap showed reduced growth rate, decreased electric membrane potential, and elevated intracellular ATP content in comparison to the wild type. Blue light induced a hyperpolarization of the membrane potential in both strains. The analysis of oxidative and phosphorylation activities of mitochondria isolated from the two strains has revealed that nap utilized more efficient oxidative pathways. The higher intracellular ATP content in the nap was presumably due to impaired transport systems of the plasma membrane, and to a lesser extent to the functioning of the fully competent respiratory chain. The excess ATP possibly accounts for carotenoid accumulation in the mutant.

Purpose: Previous studies focused on the negative effects of Internet use such as obesity, depression, and addiction. However, few studies investigated whether the Internet use for an appropriate time has positive effects on adolescents' health. Thus, the purpose of the study was to examine the dose-response relationship between Internet use for non-academic purposes (NAP) and happiness/stress in adolescents. Methods: This study used data from the 2013 Korea Youth Risk Behavior Web-Based Survey. A total of 72,435 adolescents were included. Rao-Scott ${\chi}^2$ and multiple logistic regression were conducted. To test the dose-response relationship, this study examined how happiness/stress changed with increase in the time of Internet use for NAP. Results: After controlling for general characteristics, the odds ratios for being unhappy and stressful were lowest in adolescents using the Internet for NAP for more than 0 hour and less than an hour a day. Interestingly, students who did not use the Internet for NAP had a significantly higher risk of being unhappy/stressful than those using for more than 0 hour and less than an hour a day. Conclusion: Internet use for NAP for more than 0 hour and less than an hour a day has positive effects on happiness/stress in adolescents.
