Doped-Chamber Deposition of Intrinsic Microcrystalline Silicon Thin Films and Its Application in Solar Cells

A series of microcrystalline silicon thin films were fabricated by very high frequency plasma enhanced chemical vapor deposition （VHF-PECVD） at different silane concentrations in a P chamber. Through analysis of the structural and electrical properties of these materials,we conclude that the photosensitivity slightly decreased then increased as the silane concentration increased,while the crystalline volume fraction indicates the opposite change. Results of XRD indicate that thin films have a （220） preferable orientation under certain conditions. Microcrystalline silicon solar cells with conversion efficiency 4. 7% and micromorph tandem solar cells 8.5% were fabricated by VHF-PECVD （p layer and i layer of microcrystalline silicon solar cells were deposited in P chamber）, respectively.

Physical Properties and Electrochemical Performance of Solid K_2FeO_4 Samples Prepared by Ex-situ and in-situ Electrochemical Methods

K2FeO4 powders were synthesized by the ex-situ and in-situ electrochemical methods, respectively, and characterized by infrared spectrum （IR）, scanning electron microscopy （SEM）, X-ray powder diffraction （XRD） and BET. Their electrochemical performances were investigated by means of galvanostatic discharge and electrochemi-cal impedance spectroscopy （EIS）. The results of physical characterization showed that the two samples have simi-lar structural features, but their surface morphologies and oriented growth of the crystals are different, which results in smaller specific surface area and lower solubility of the ex-situ electrosynthesized K2FeO4 sample. The results of discharge experiments indicated that the ex-situ electrosythesized K2FeO4 electrode has much larger discharge ca-pacity and lower electrode polarization than the in-situ electrosynthesized K2FeO4 electrode. It was found from the results of EIS that lower electrochemical polarization might be responsible for the improvement on the discharge performance of the ex-situ electrosynthesized K2FeO4 electrode.

Location and Its Semantics in Location-Based Services

Starting with a simple presentation of location determination techniques, physical location and geographic location as two common kinds of location description methods are discussed. The semantic location concept is then introduced and a correction is given, which especially emphasizes that location property is an important part of semantic location. By analyzing the connotation and extension of every geographic location, what should be contained in a location property is determined. Using a hierarchical model, the relations and associations among locations are clearly described. To realize a formalized description of semantic location, an ontology technique that can adequately describe semantic information of location is used. Organized by ontology web language, a location ontology model allows semantic location to be read and processed by computer. The location ontology model realizes the knowledge description of location information and establishes an important foundation to personalized preference services in location based services.

A Study of Localization of Task-Based Language Teaching in China

In view of a series of challenges since Task-Based Language Teaching(TBLT) was introduced into China, we interviewed 14 front-line teachers in primary and secondary schools about their viewpoints and classroom strategies of TBLT. The results show teachers’ willingness to use TBLT. They adopt flexible teaching procedures, apply TBLT creatively, and explore task-based language assessment. The authors argue for inclusive non-doctrinaire approaches to TBLT, and propose to construct localized TBLT theory and practice with Chinese characteristics.

Sample Preparation of Urine Samples Prior to CE-MS in Toxicological Analysis

Capillary electrophoresis （CE） coupled with mass spectrometry （MS） with a sheath liquid interface is nowadays recognized as a powerful separation technique for drugs and metabolites analysis in human urine and can be applied in numerous fields such as clinical toxicology, drug substitution monitoring, forensic sciences and antidoping. With an acidic background electrolyte containing 15 mM ammonium formate at pH 2.5 and a sheath liquid consisting in a mixture of isopropanol/water （50：50, v/v） with 0.5% formic acid, CE-ESI-MS in positive mode demonstrated excellent performance for simultaneous analysis of basic drugs of abuse and metabolites in urine （e.g. cocaine, amphetamine, morphine and phase II metabolites）. To achieve the desired level of sensitivity, two injection modes and three sample pre-treatments were evaluated. The detection of basic drugs and phase Ⅱ metabolites in diluted urine was achieved at concentrations above 1μg/mL. In order to enhance sensitivity, a sample preparation was required. A liquid-liquid extraction （LLE） was compared with solid-phase extraction. LLE was performed at alkaline pH and samples were electrokinetically injected. A chemometric approach （Doehlert design） was carried out in order to determine optimized injection parameters. Limits of detection （LOD） down to 10 ng/mL were reached with field-amplified sample injection but phase II metabolites were not extracted. Therefore, instead of LLE a SPE was performed on C 18 sorbent, and elution fraction after washing step containing phase Ⅱ metabolites was loaded on mixed-mode anion exchanger cartridges. After electrokinetic injection, this two-step SPE allowed LOD ca. 10 ng/mL for drugs and phase Ⅱ metabolites.

Science and Sensibility： A Restudy of Snow＇s ＂The Two Cultures＂ in The Masters

Charles Percy Snow declared his influential Rede Lecture, ＂The Two Cultures＂, in 1959. In his famous lecture, he told us that the most powerful revolutionary force in the world today is science, science is essentially progressive, and the scientific culture is also a newer one. So Snow, after excluding scientific culture from the whole culture, calls the rest of the whole culture traditional culture. In his opinion, science is more important than humanities. All these ideas are faithfully reflected in his earlier literary work The Masters （1972b）. Snow＇s favor toward men of sciences in the novel is self-evident. ＂The Masters, therefore, may be considered as a political science novel rather than as a political novel＂. It was the Industrial Revolution which created our sensibility

Popular Literary Tradition and the Localization of Early Chinese Films

As a new form of artistic expression, film has gone through a history of more than 100 years in China. Focusing on the aesthetic taste of the underclass, popular literary tradition, which highlights appreciation habits of the citizen stratum, is the quintessence of Chinese traditional culture. Breaking through the mode of Western films, the early Chinese film, referring to artistic elements in story-telling script, fiction, and drama in Song and Yuan Dynasties, has created new film genres of ＂unofficial historical film＂ and martial-art film which are positive results of the localization of early Chinese films. Though the unofficial historical film failed in adapting the theme of popular literature, its groundbreaking significance is still worth approving

A damage constitutive model of rock-like materials containing a single crack under the action of chemical corrosion and uniaxial compression

To describe the deformation and strength characteristics of the corroded rock-like specimens containing a single crack under uniaxial compression,a damage constitutive model combining hydro-chemical damage with coupling damage of micro-flaws and macro-cracks is proposed.Firstly,based on phenomenological theory,the damage variable of the rock-like specimens subjected to water environment erosion and chemical corrosion is obtained.Secondly,a coupled damage variable for cracked rock-like specimens is derived based on the Lemaitre strain equivalence hypothesis,which combines the Weibull statistical damage model for micro-flaws and the fracture mechanics model for a macro single crack.Then,considering the residual strength characteristics of the rock-like materials,the damage variable is modified by introducing the correction coefficient,and the damage constitutive model of the corroded rock-like specimens with a single crack under uniaxial compression is established.The model is verified by comparing the experimental stress−strain curves,and the results are in good agreement with those provided in the literature.Finally,the correction coefficient of the damage variable proposed in this paper is discussed.The damage constitutive model developed in this paper provides an effective method to describe the stress−strain relationship and residual strength characteristics of the corroded rock-like specimens with a single crack under uniaxial compression.

A Genetic Algorithm-based Approach to Scheduling of Batch Production with Maximum Profit

The optimal scheduling of multi-product batch process is studied and a new mathematics model targeting the maximum profit is proposed, which can be solved by the modified genetic algorithm (MGA) with mixed coding (sequence coding and decimal coding) developed by us. In which, the partially matched cross over (PMX) and reverse mutation are used for the sequence coding, whereas the arithmetic crossover and heteropic mutation are used for the decimal coding. In addition, the relationship between production scale and production cost is analyzed and the maximum profit is always a trade-off of the production scale and production cost. Two examples are solved to demonstrate the effectiveness of the method.

Atomic Force Microscopy in Cytological Diagnosis of Tumors of Different Localization

Objective cytomorphometric differential diagnostic criteria of breast, thyroid, stomach, and cervical cancer were obtained with the method of atomic force microscopy. Statistically significant increased ratio of the nucleus and the cytoplasm height and the nucleolus and the nucleus height is characteristically for cancer cells compared to normal cells. AFM method allows determining the viral changes in squamous cells by detecting the perinuclear area of enlightenment. AFM allows objectifying immunocytochemistry data by quantifying the height of immune complexes. Possibilities of quantitative immunocytochemistry with AFM are shown in the model of Her2/neu oncoprotein expression in breast cancer and thyroglobulin in papillary thyroid cancer.

Cross-Cultural Bioethics at an International University in Japan

Ritsumeikan Asia Pacific University （APU） in Beppu city, Japan has a large body of students from well over 90 countries, especially from the Asia Pacific region, including Japanese, Korean, Chinese, Thai, Vietnamese, and Indonesian students. To improve analytical thinking skills among college students, a course on ＂bioethics＂ was introduced and offered in two consecutive semesters to undergraduate students for which 245 students registered at each semester. The course was taught in the form of 14 lecture and discussion sessions, each for 95 minutes based on the content of A Cross-Cultural Introduction to Bioethics （2006） edited by Darryl Macer, and reviewed a wide variety of ethical and bioethical issues. In the next semester, the students received a similar teaching content that was rearranged to reflect the 15 universal principles of bioethics and human rights covered in the Bioethics Core Curriculum （2008）. Case studies were also added to each unit of the Core Curriculum with the support of the UNESCO＇s Asia Pacific Regional Office, Bangkok （Case Studies for Bioethics 2010）. To evaluate the results of teaching and to compare the achieved objectives between the two groups of students, a short questionnaire was given to all students who finished the course and took up the final written examination. In the whole, 454 students （225 in group I and 229 in group 2） completed the course and took the final examination and 427 （218 in group 1 and 209 in group 2） responded to the questionnaire which inquired into their interest in the discussion of bioethical issues： why they believed they were important, and what they had learned through them. The results of the questionnaire have been examined and compared to evaluate the success of ＂bioethics＂ in stimulating the interest and thinking ability of the students and enriching their experience of a cross-cultural discussion over bioethical issues using universal principles as general guidance. The result of this examination was so impressive that from 2011 bioethics has been formalized into the reformed curriculum of our international school.

Effect of Multiple Coatings of One-step Self-etching Adhesive on Microtensile Bond Strength to Primary Dentin

Objective To investigate the effect of multiple coatings of the one-step self-etching adhesive on immediate microtensile bond strength to primary dentin.Methods Twelve caries-free human primary molars were randomly divided into 2 groups with 6 teeth each.In group 1,each tooth was hemisected into two halves.One half was assigned to control subgroup 1,which was bonded with a single-step self-etching adhesive according to the manufacturer's instructions;the other half was assigned to experimental subgroup 1 in which the adhesive was applied three times before light curing.In group 2,the teeth were also hemisected into two halves.One half was assigned to control subgroup 2,which was bonded with the single-step self-etching adhesive according to the manufacturer's instructions;the other half was assigned to experimental subgroup 2 in which three layers of adhesive were applied with light curing each successive layer.Microtensile bond strength was immediately tested after specimen preparation.Results When the adhesive was applied three times before light curing,the bond strength of the experimental subgroup 1(n=33,57.49±11.61 MPa) was higher than that of the control subgroup 1(n=31,49.71±11.43 MPa,P<0.05).When using the technique of applying multiple layers of adhesive with light curing each successive layer,no difference of immediate bond strength was observed between the control subgroup 2 and the experimental subgroup 2(P>0.05).Conclusion Multiple coatings of one-step self-etching adhesive can increase the immediate bond strength to primary dentin when using the technique of light-curing after applying three layers of adhesive.

Japanese Mythology From Ethnological Perspectives

Comparative studies of Japanese mythology have developed since the 1920s above all through eftbrts of Japanese ethnologists. They have paid attention to the possible ethno-cultural complexes that brought mythological motifs into the archipelago. In the present paper the theories set forth by Nobuhiro Matsumoto, Akihide Mishina, and Masao Oka are examined in terms of retrospect. The result shows that they shared the view that at least three different complexes, based in ancient Yamato, Izumo, and Kyushu respectively, contributed to the formation of Japanese mythology compiled in the 8th century CE （Common Era）. Their assumptions were synthesized by Taryo Obayashi in 1961, the hypothesis which has survived until today. In future we should cooperate with other disciplines and address the formation process of Japanese mythology.

Manabi as an Altemative Concept of Learning in Educational Discourses

This paper considers a theory and practices of Japanese manabi （学） as an alternative concept of learning in the era of post-globalization. Although the term manabi is widely used as the translation of learning and Lernen in the field of pedagogy and in Japanese schools, it is important to understand its meaning, since the meaning of manabi is a comprehensive concept that differs semantically from the words learning, Lernen, and Bildung in the Western words. Faced with the globalization in the 21st century, there has been a tendency to promote educational reform and curriculum policies that could be characterized as ＂learnification＂ in which ＂21st century skills,＂ ＂competency-based learning,＂ and ＂learner-centered education＂ are emphasized. While the Western idea of learning that highlights active self is attractive to change classroom practices from the transmission of knowledge to an innovative style of active, collaborative, communicative learning, and problem-solving, Japanese education sustains traditional values that derive from selflessness and nothingness in Eastern philosophy.

The Four Different Aspects of Man-World Relations and the Ontological Nature of Culture

In traditional philosophy, man is usually treated as a subject of knowledge, not as a subject of activity. This naturally led to an ignorance of his creative side and had its echoes in the models of the world put forward. Thus, when the world was mentioned the world meant was that perceived by man and the world man created or planned to create himself was given either a secondary treatment or else it was completely forgotten. But, as man is carrier of active spirit, the things he creates have their place in this world along those created by God. It is without doubt that things created by man are not produced against God＇s will. Still, human creativity is the corruption of the original creation, of the harmony of the world, of the book of nature. Man brings order, so to speak, to the world. He achieves this however at the cost of corrupting the Great Order within some narrow limits. Man himself is among the many highly interesting books written before and there exist as many variations of this book as there are human beings. What is the most difficult for man is though, to read his own book, to understand himself. In this article, the concept of the culture as a human creation is analyzed in the light of Man-World and Man-Nature-God relations. In this case, the author firstly explains the four different world models and then determines the boundaries of science and culture, as well as the individual and social strata of culture.

The Clinical Use of Mediator Release Test in Food Sensitivities

Food sensitivities are non-IgE-mediated, non-coeliac, dose-dependent and delayed systemic responses to food. They consist of a highly complex class of adverse food reactions; however, their last phase is the release of mediators from leukocytes. The Mediator Release Test （MRT） is a functional measure of sensitivity-based inflammatory responses. It is an end-point test, which can account for the widest range of triggering mechanisms involved in sensitivity reactions, including both innate and adaptive pathways. MRT not only tests reactions to foods, food-chemicals, and other substances, but also reliably quantifies the degree of the inflammatory response. The test opens the new therapeutic options for food sensitivities.

Evolution of research methods in Psychology

psychology has more than 100 years developmwnt history, and make great success during this time. But in the after development, psychology met the unprecedented contradiction and conflict, facing division and broken, and in the embrassmed situation of divorced from society, positive psychology is emerge as the times requirement in this crisis. In order to better guide the development to positive psychology, providing philosophical theory and instructions on methodology,it is neeessary to discuss about the positive psycholog from a philosophical perspective. Since 1879 the western modern psychology come into being, the psychology of natural science orientation has been the mainstream of psychology. In addition, admit the uniqueness of man, attention to people＇s inner experience of humanistic psychology, also occupies a space in the confrontation with the reflection of the mainstream of scientific psychology, positive psychology from the research content to lead psychology to another port, but the research methods are not completely abandon the previous research methods of positivism psychology, but more introduced humanism based on the oositivism research method of scientific oriented.
