This study is to focus on an innate creative 'spirituality' of Weimar Bauhaus' pedagogical thoughts and their backgrounds. In particular, this notes three elements of Universal mysticism, Orientalism in early Bauhaus including Expressionism, and Froebelian Education as the more practical among the romantic legacies as a source of modernism. Arguably, through these researches, just as the expressionists represent the crystallization of glass as the spirit, the important that should be noticed is explained as the fact that a panentheistic Idea of matter and spirit as a whole had been spreading to be recognized consciously or unconsciously; in other words, this awakening as dualistic monism might be one of the greatest peculiarities of modernity, and, as the fact that the universal thought and principle of 'panentheism' emphasizing a 'divine' artistic volition which is immanent in the individual is implanted first of all fundamentally by Froebelian educational influences.

As movies entered the digital age, they quickly changed from group creation to individual creation. In particular, documentary films began to produce diverse and excellent works while dealing with extremely personal subjects and themes rather than heavy subjects. Especially in the 1990s, when the digital era began in earnest, Japan began to shift away from heavy political and social topics from documentaries to extremely personal subjects, and the subject matter became very diverse. In this paper, we would like to examine the concept, type, and characteristics of private documentaries that emerged as new forms of documentaries following the advent of the full-fledged digital era since the 90s, citing concrete examples of representative private documentary works since the 90s in Japan.

Laws regarding to Arbitration in North Korea are Arbitration Act, Foreign Economic Arbitration Act, Regulations on the Foreign Trade Arbitration Commission, Regulation for treatment of cases in Arbitration Commission, Rules of Hearing. North Korea has enacted the laws related to Arbitration including Arbitration Act enacted in 1995 and Foreign Economic Arbitration Act enacted in 1999. In the North Korea's planed economy system, as there will be many disputes among organizations, companies, other Institutions Arbitration Act resolves the disputes to compete the economic plan. North Korea's Arbitration Act is different from Normal Arbitration Acts in particular other socialist states in view of arbitration agreement and selection of arbitrator and functions as the tools controlling the members of North Korea and have the characteristics such as national arbitration system and mixture of criminal trial and governmental control and strict legal control system on violent acts in North Korea's plan and plan regulation. And North Korea's Arbitration Act deals with the civil disputes and limits the parties and subject matter of arbitration. The parties in dispute such as organizations, companies, other Institutions could apply for arbitration to Central Arbitration Body and Provincial (City under the direct control of Government) Arbitration Body and Sectional Arbitration Body. The purpose of this paper is to contribute to the enhancement of the understanding arbitration in North Korea by studying the clauses in the Arbitration Act.

Among various fuel cells, solid oxide fuel cells (SOFCs) offer the highest energy efficiency, when taking into account the thermal recycling of waste heat at high temperature. However, the highest efficiency and lowest pollution for a SOFC can be achieved through the sophisticated control of its constituent components such as electrodes, electrolytes, interconnects and sealing materials. The electrochemical conversion efficiency of a SOFC is particularly dependent upon the performance of its electrode materials. The electrode materials should meet highly stringent requirements to optimize cell performance. In particular, both mass and charge transport should easily occur simultaneously through the electrode structure. Matter transport or charge transport is critically related to the configuration and spatial disposition of the three constituent phases of a composite electrode, which are the ionic conducting phase, electronic conducting phase, and the pores. The current work places special emphasis on the quantification of this complex microstructure of composite electrodes. Digitized images are exploited in order to obtain the quantitative microstructural information, i.e., the size distributions and interconnectivities of each constituent component. This work reports regarding zirconia-based composite electrodes.

In the field of control technology, too, it is about time that the students should free themseleves from the paradigm of Newtonian mechanics. Otherwise, they might fail to grasp the essence of control. Now, let us consider the essence of control. Control consists of manipulating a particular object, matter, energy of environment on the basis of certain medium information. (measurement data, force, etc.) So, we shall look into the methods of manipulation. Here, we consider natural control, constraining control, and hybrid control as basic methods of manipulation. In this paper, we would like to put forward the daring proposal that it's called a Holon-type hybrid control system. It is intended to control a plat with complicated or unknown characteristics where a conventional control theory is not easy to apply. A prototype system has been developed and applied to a real plant. The control system is a multi-layer system. Each layer includes different control input. The important features of the system are as follows: 1) Each layer behaves autonomously and also cooperates with each other to optimize the whole plant. 2) The controller optimizes a plant without mathematical models when these models are not easy to obtain.

Ambient air pollution (AAP) and particulate matters (PM) have been closely associated with adverse health effects such as respiratory disease and cardiovascular diseases. Previous studies have examined the adverse health effects associated with short- and long-term exposure to AAP and outdoor PM on respiratory disease. However, the effect of PM size ($PM_{2.5}$ and $PM_{10}$) on cardiovascular disease has not been well studied. Thus, it remains unclear how the size of the inhalable particles (coarse, fine, or ultrafine) affects mortality and morbidity. Airborne PM concentrations are commonly used for ambient air quality management worldwide, owing to the known effects on cardiorespiratory health. In this article, we assess the relationship between cardiovascular diseases and PM, with a particular focus on PM size. We discuss the association of $PM_{2.5}$ and $PM_{10}$, nitrogen dioxide ($NO_2$), and elemental carbon with mortality and morbidity due to cardiovascular diseases, stroke, and altered blood pressure, based on epidemiological studies. In addition, we provide evidence that the adverse health effects of AAP and PM are more pronounced among the elderly, children, and people with preexisting cardiovascular and respiratory conditions. Finally, we critically summarize the literature pertaining to cardiovascular diseases, including atherosclerosis and stroke, and introduce potential studies to better understand the health significance of AAP and PM on cardiovascular disease.

This study was conducted to better understand the effect of the classroom literacy environment on the young children's vocabulary abilities, and the concepts of print matter. The subjects consisted of 276 children aged 3 to 5 enrolled in 93 classrooms in child-care centers and kindergartens. The Early Language & Literacy Classroom Observation Pre-K (Smith, Brady, & Anastasopoulos, 2008), the Picture Vocabulary Test (Kim, Jang, Yim, & Bae, 1995) and the Concepts About Print (Kim & Kim, 2004) were used for the purposes of this study. The data collected were analyzed by means of ANOVA, and regression analysis. The results indicated that the vocabulary abilities and print-concepts of children aged 3-5 were more likely to increase when a rich classroom environment was provided for the children's literacy development. In particular, it was found to be important for children's language and Literacy development to provide them with an enriched 'language environment' within the classroom, the quality of 'books and book reading', and the active utilization of 'print and early writing' all being important elements of this.

$PM_{2.5}$ is one of critical air pollutants due to its high absorbability of heavy metallic fumes, PAH and bacillary micro organisms. Such a fine particulate matter is often formed through various nucleation processes including condensation. This study attempts to find the nucleation behaviors of $PM_{2.5}$ arisen from coal power stations using a classical heterogeneous Fletcher's theory. The numerical simulation by C-language could approximate the nucleation process of $PM_{2.5}$ from water vapor, of which approach revealed the required energy for embryo formation and embryo size and nucleation rate. As a result of the calculation, it was found that wetting agents could affect the particle nucleation in vapor condensation. In particular, critical contact angle relates closely with the vapor saturation. Particle condensation could be reduced by lowering the angles. The wetting agents aid to decrease the contact angle and surface tensions, thereby may contribute to save the formation energy.

Diesel engines have the advantages of higher thermal efficiency and lower CO2 emissions than gasoline engines, but have the disadvantages that particulate matter (PM) and nitrogen oxides (NOx) emissions are greater than those of gasoline engines. In particular, nitrogen oxides (NOx) emitted from diesel engines generates secondary ultrafine dust (PM2.5) through photochemical reactions in the atmosphere, which is fatal to humans. In order to reduce nitrogen oxides (NOx), pre-treatment systems such as EGR, post-treatment systems such as LNT and Urea SCR have been actively studied. The Urea SCR consists of an injection device injecting urea agent and a catalytic device for reducing nitrogen oxides (NOx). The nitrogen oxide (NOx) reduction performance varies greatly depending on the urea uniformity in the exhaust pipe. In this study, spray characteristics according to the spray hole structure were confirmed, and the influence of spray uniformity on spray characteristics was studied through engine evaluation.

An important goal in diesel engine research is the development of a means to reduce the emissions of nitrogen oxides (NOX). The use of a cooled exhaust gas recirculation (EGR) system is one of the most effective techniques currently available for reducing nitrogen oxides. Since Particular Matter (PM) fouling reduces the efficiency of an EGR cooler, a trade-off exists between the amount of NOX and PM emissions, especially at high engine loads. In the present study, engine dynamometer experiments have been performed to investigate the heat exchange characteristics of the stack-type EGR coolers with wave fin pitches of 3.6 and 4.6 mm. The results show that the heat exchange effectiveness is decreased as surface area decrease with pitch of 4.6 mm due to PM fouling. As surface area increase at pitch of 3.6 mm, super-cooling happens in the recirculated exhaust gas.
