This research presents the relationship building between the supervisor and supervisee through the supervision process in a narrative inquiry. The supervisory relationships of the supervisor A and supervisee B, and the effects they have on the relationship between the two are described in as factual terms as possible. The results imply that genuineness and openness are the core components of relationship. Especially, in the case of a highly hierarchical relationship, where it is often easy for the supervisor to employ hidden tactics, efforts on the part of the supervisor's endeavor to develop unconditional acceptance can be helpful in establishing a more open-minded attitude. As a result, the common view in the literature that attributes relationship hierarchy to cultural factors may need to be reexamined. This research provides evidence that in the case of supervision and training in counseling, establishing an environment of acceptance, trust and rapport can help advance the supervisory relationship to a less hierarchical form.

Screen printing is commonly used to form the front/back electrodes in silicon solar cell. But it has caused high resistance and low aspect ratio, resulting in decreased conversion efficiency in solar cell. Recently the plating method has been combined with screen-printed c-Si solar cell to reduce the resistance and improve the aspect ratio. In this paper, we investigated the effect of light induced silver plating with screen-printed c-Si solar cells and compared their electrical properties. All wafers were textured, doped, and coated with anti-reflection layer. The metallization process was carried out with screen-printing, followed by co-fired. Then we performed light induced Ag plating by changing the plating time in the range of 20 sec~5min with/without external light. For comparison, we measured the light I-V characteristics and electrode width by optical microscope. During plating, silver ions fill the porous structure established in rapid silver particle sintering during co-firing step, which results in resistance decrease and efficiency improvement. The plating rate was increased in presence of light lamp, resulting in widening the electrode with and reducing the short-circuit current by shadowing loss. With the optimized plating condition, the conversion efficiency of solar cells was increased by 0.4% due to decreased series resistance. Finally we obtained the short-circuit current of 8.66 A, open-circuit voltage of 0.632 V, fill factor of 78.2%, and efficiency of 17.8% on a silicon solar cell.

Atomic layer deposition (ALD), utilizing self-limiting surface reactions, could offer promising perspectives for future efficient energy conversion devices. The capabilities of ALD for surface/interface modification and construction of novel architectures with sub-nanometer precision and exceptional conformality over high aspect ratio make it more valuable than any other deposition methods in nanoscale science and technology. In the context, a variety of researches on fabrication of active materials for energy conversion applications by ALD are emerging. Among those materials, one-dimensional nanotubular titanium dioxide, providing not only high specific surface area but also efficient carrier transport pathway, is a class of the most intensively explored materials for energy conversion systems, such as photovoltaic cells and photo/electrochemical devices. The monodisperse, stoichiometric, anatase, TiO2 nanotubes with smooth surface morphology and controlled wall thickness were fabricated via low-temperature template-directed ALD followed by subsequent annealing. The ALD-grown, anatase, TiO2 nanotubes in alumina template show unusual crystal growth behavior which allows to form remarkably large grains along axial direction over certain wall thickness. We also fabricated dye-sensitized solar cells (DSCs) introducing our anatase TiO2 nanotubes as photoanodes, and studied the effect of blocking layer, TiO2 thin films formed by ALD, on overall device efficiency. The photon convertsion efficiency ~7% were measured for our TiO2 nanotubebased DSCs with blocking layers, which is ~1% higher than ones without blocking layer. We also performed open circuit voltage decay measurement to estimate recombination rate in our cells, which is 3 times longer than conventional nanoparticulate photoanodes. The high efficiency of our ALD-grown, anatase, TiO2 nanotube-based DSCs may be attributed to both enhanced charge transport property of our TiO2 nanotubes photoanode and the suppression of recombination at the interface between transparent conducting electrode and iodine electrolytes by blocking layer.

Flavanone-3-hydroxylase (F3H) is one of the key enzymes for the biosynthesis of flavonals, anthocyanins, catechins and proanthocyanins. F3H catalyzes the $3{\beta}$-hydroxylation of (2S)-flavonones to form (2R, 3R)-dihydroflavonols. In this report, we isolated a full-length cDNA of RocF3H from black raspberry (Rubus occidentalis L.) using a reverse transcriptase-PCR and rapid amplification of the cDNA ends (RACE)-PCR. The full-length cDNA of RocF3H contains a 1,098 bp open reading frame (ORF) encoding a 365 amino acid protein with a calculated molecular weight of about 41.1 kDa and isoelectric point (pI) of 5.45. The genomic DNA analysis revealed that the RocF3H gene had three exons and two introns. Comparison of the deduced amino acid sequence of the RocF3H with other F3Hs revealed that the protein is highly homologous with various plant species. The conserved amino acids ligating the ferrous iron and the residues participating in the 2-oxoglutarate binding (R-X-S) were found in RocF3H at the similar positions to other F3Hs. Southern blot analysis indicated that RocF3H exist a multi-gene family. The isolation of RocF3H gene will be helpful to further study the role of F3H gene in the biosynthesis of flavonoids in R. occidnetalis.

This article is concerned about a reason for which Cervantes participates an arabic author named Benengeli and morisco translator in his work instead of christian author. From the multi-cultural point of view, the time in which Don Qujote was published, belongs to the Golden Age. In other words, the society can not be supported by the ideology of Purity of Blood in that the morisco, converso (Christian Jewish) have been permitted to coexist in the name of christian proselyte or New Christian despite of invisible discrimination. An invisible discrimination is based on the prejudice and negative stereotype of Old Christian against the New Christian. Cervantes offers an o open space for readers to participate in the creative reading, giving up the absolute authority of author named Benengeli. The deep-rooted prejudice against morisco or muslim author makes the readers of Don Quijote do reinterpret the contents and have question about his sincerity. This disbelief is partly on the basis of hypothesis that Don Quijote would be passed on orally by an arabic or morisco. Leaving the hypothesis alone, Romance, festival performances of morisco or the aljamia literature in the Iberian Peninsula have the chivalry or knights of the Occident. The chivalry in Romance of morisco means that morisco would seek assimilation into the mainstream of Occidental Christian community. At the same time, morisco would be faced with the dilemma of loss of religious identity. But Taqiyya, islamic doctrine, offsets the dilemma between yearning to assimilate into mainstream and religious conscience of morisco in that Taqiyya permits morisco to convert to Christianity in case that they are in danger of life or the following risk. From this point of view, There is no room for doubt about the fact that Taqiyya contributed to social assimilation or multicultural society of the Iberian Peninsula. It has been a long time since a narrow-minded religious dogma and ideology became a anachronistic relic in multicultural society of Spain such as the Purity of Blood. From a relative viewpoint, Don Quijote provides a ground for the collective intelligence among christian, muslim(morisco) and converso through a liberal community between readers and authors who form a pluralistic society.

Based on basic studies on the current status index of BF certification application for school facilities according to the BF certification implementation, this study sought to improve the direction of the different BF certification evaluation indexes for school facilities by investigating and analyzing the status of BF Reservation Certification for elementary schools. A comparative analysis of the status and evaluation indexes of 30 elementary schools in the Gyeongsang region that included indicators of external and internal facilities, sanitary facilities, guidance facilities, and other facilities indicated that school facilities are insufficient to discriminate based on criteria and thus need to be updated for accurate grading. For school facilities that are open for anyone to use, quality improvement should be induced by improving standards and adjusting points for items that earn middle and lower grades.

Defect severity that is a measure of the impact caused by the defect plays an important role in software quality activities because not all software defects are equal. Earlier studies have concentrated on defining defect severity levels, but there have almost never been trials of measuring module severity. In this paper, first, we define a defect severity metric in the form of an exponential function using the characteristics that defect severity values increase much faster than severity levels. Then we define a new metrics set for software module severity using the number of defects in a module and their defect severity metric values. In order to show the applicability of the proposed metrics, we performed an analytical validation using Weyuker's properties and experimental validation using NASA open data sets. The results show that ms is very useful for measuring the module severity and msd can be used to compare different systems in terms of module severity.

In this study, the electrochemical behavior of Sm on the binary liquid Al-Ga cathode in the LiCl-KCl molten salt system is investigated. First, the co-reduction process of Sm(III)-Al(III), Sm(III)-Ga(III), and Sm(III)-Ga(III)-Al(III) on the W electrode (inert) were studied using cyclic voltammetry (CV), square-wave voltammetry (SWV) and open circuit potential (OCP) methods, respectively. It was identified that Sm(III) can be co-reduced with Al(III) or Ga(III) to form Al_zSm_y or Ga_xSm_y intermetallic compounds. Subsequently, the under-potential deposition of Sm(III) at the Al, Ga, and Al-Ga active cathode was performed to confirm the formation of Sm-based intermetallic compounds. The X-ray diffraction (XRD) and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) analyses indicated that Ga₃Sm and Ga₆Sm intermetallic compounds were formed on the Mo grid electrode (inert) during the potentiostatic electrolysis in LiCl-KCl-SmCl₃-AlCl₃-GaCl₃ melt, while only Ga₆Sm intermetallic compound was generated on the Al-Ga alloy electrode during the galvanostatic electrolysis in LiCl-KCl-SmCl₃ melt. The electrolysis results revealed that the interaction between Sm and Ga was predominant in the Al-Ga alloy electrode, with Al only acting as an additive to lower the melting point.

Although there are many commercially available training software programs for pharmacokinetics, they lack flexibility and convenience. In this study, we develop simulation software to facilitate pharmacokinetics education. General formulas for time courses of drug concentrations after single and multiple dosing were used to build source code that allows users to simulate situations tailored to their learning objectives. A mathematical relationship for a 1-compartment model was implemented in the form of differential equations. The concept of population pharmacokinetics was also taken into consideration for further applications. The source code was written using R. For the convenience of users, two types of software were developed: a web-based simulator and a standalone-type application. The application was built in the JAVA language. We used the JAVA/R Interface library and the 'eval()' method from JAVA for the R/JAVA interface. The final product has an input window that includes fields for parameter values, dosing regimen, and population pharmacokinetics options. When a simulation is performed, the resulting drug concentration time course is shown in the output window. The simulation results are obtained within 1 minute even if the population pharmacokinetics option is selected and many parameters are considered, and the user can therefore quickly learn a variety of situations. Such software is an excellent candidate for development as an open tool intended for wide use in Korea. Pharmacokinetics experts will be able to use this tool to teach various audiences, including undergraduates.
