Cleaner production is of substantial importance in changing the environmental approach within advanced industrialized countries. The critical principles involve fundamental understanding of diverse industrial processes, adherence to the earliest techniques of a hierarchy for reducing wastes, and utilization of an underlying thought process to achieve pollution prevention successes that are both technically feasible and cost-effective. Chemical engineering has played a major and unique role in this environmental field. Improving the sustainability of cleaner production will rest on including this subject in the curriculum of university engineering.

본 논문은 서파 유희의 "춘추괄례분류'를 주요 연구 대상으로 삼아, 이 책에 보이는 범례 분류의 특징 및 그 학술적 가치를 밝히는 것을 목적으로 한다. 이 책은 "춘추" 범례의 기본 원칙을 바탕으로 정형화된 범례를 규정한 일종의 범례 종합 분류집이다. 서파는 "춘추" 범례 분류의 두 가지 기본 원칙을 제시하였다. 첫째, "춘추" 라는 책의 성격과 체계를 명확하게 규정함으로써 "춘추" 범례를 분류하게 된 배경을 밝혔다. 둘째, "춘추" 에 존재하는 필법과 의리가 범례 분류의 기준이 된다는 점을 천명하였다. 서파는 이러한 범례의 기본 원칙에 따라 유형별로 범례를 분류하여 정형화된 범례 규정을 확정함으로써 올바른 "춘추" 해석을 위한 토대를 마련하고자 하였다. 나아가 이 범례 규정이 잘못된 "춘추" 해석이 나올 가능성을 사전에 차단함과 동시에 왜곡된 이론의 존립 근거도 없애는 역할을 수행할 수 있을 것이라고 판단했다. 이 책은 다양한 범례의 체계적인 분석과 종합을 통해 "춘추" 범례 분류의 표준화를 시도했다는 점에서 학술적 가치가 매우 크다고 평가할 수 있다.

This review examines computational simulations of thermoelectric properties, such as electrical conductivity, Seebeck coefficient, and thermal conductivity. With increasing computing power and the development of several efficient simulation codes for electronic structure and transport properties calculations, we can evaluate all the thermoelectric properties within the first-principles calculations with the relaxation time approximation. This review presents the basic principles of electrical and thermal transport equations and how they evaluate properties from the first-principles calculations. As a model case, this review presents results on $Bi_2Te_3$ and Si. Even though there is still an unsolved parameter such as the relaxation time, the effectiveness of the computational simulations on the transport properties will provide much help to experimental scientist researching novel thermoelectric materials.

Design of novel materials in renewable energy systems plays a key role in powering transportation vehicles and portable electronics. This review introduces the research work of first principles-based computational design for the materials over the last decade to accomplish the goal with less financial and temporal cost beyond the conventional approach, especially, focusing on electrocatalyst toward a proton exchange membrane fuel cell (PEMFC). It is proposed that the new method combined with experimental validation, can provide fundamental descriptors and mechanical understanding for optimal efficiency control of a whole system. Advancing these methods can even realize a computational platform of the materials genome, which can substantially reduce the time period from discovery to commercialization into markets of new materials.

Healthcare facilities undergo substantial renovation and remodeling to accommodate changing technologies and regulatory requirements, thereby generating significant quantities of construction-related wastes, and subjecting building occupants to noise, dust, and other health impacting disruptions associated with construction. By designing flexible, adaptive, generic spaces, buildings can better respond to changes imposed by architectural composition of interpersonal and community space of hospital ward with minimum needs renovation and remodeling. This study focuses on the design principles of enhancing flexibility in architectural composition of interpersonal and community space of hospital ward. The purpose of this study is to provide fundamental data for designing interpersonal and community space of hospital ward through ecological flexible design principles with case on interpersonal and community space of hospital ward.

The Original forms of the ancient clothing have been evolved in various designs and showed each unique formativeness based on the basic principles of origami. The purpose of this study was to analyze the basic clothing formativeness in the original forms of the ancient clothing based on the principles of origami. The methods of this study were to identify significant relevant ancient clothing figures with each unique formativeness based on the principles of origami and analyze the formativeness characters and values through comprehensive literature reviews on topic-related books and theses on a foundation of triangulation of observer. The results were as follows: The significant ancient clothing figures with principles of origami were identified as kalasiris, chiton, chlamys, toga, dalmatica, paludamentium, and lorum. The formative principles applied in the ancient clothing figures were identified as exaggerated measurements, folding and unfolding, bending, and angle. And the formative characters and values were identified as potential drape realization, potential silhouette realization, potential three-dimensional design optimality, and potential three-dimensional formativeness realization. The result of this study may be used for a newer approach for the fundamental digging of clothing formativeness in advance.

Purpose: This study seeks to address the following research questions: (1) What are the fundamental principles of sports psychology that can be applied to business leadership? (2) How can these principles enhance business leadership effectiveness? As a result, the study may evaluate the necessity and benefits of incorporating sports psychology principles into business leadership practices. Research design, data and methodology: The data collection process in this study involved a systematic Literature review approach, following the prior literature analysis guidelines by numerous past studies. This methodical approach to selecting articles can be useful in synthesizing existing literature and can be referred to as Literature review and selection. Results: The literature analysis has indicated that there is much support for assumptions underpinning business leadership modules, which can be enhanced by applying sports psychology. This topic discusses the traits of self-positivity and mental toughness, goal perspective and interpersonal relationships within a team, and visualization in a sporting organization that can be implemented in business management to support organizational performance. Conclusions: All in all, it can be concluded that organizations must consider adopting Sports Psychology principles into their Leadership Development Programs. Psychological skills development training that includes mental toughness, goal setting, team cohesion,

최근 우리나라 주택 시장은 잦은 정책 변화 등 내부적 요소와 해외 경제 환경 변화 등 외부적 요소에 의해 예측할 수 없는 상황이 계속되고 있다. 특히 미래 주택 시장에 대한 가격, 수요, 공급을 예측하는 데에 있어 어려움을 겪고 있다. 이에 따라 주택 시장 변화에 대한 다양한 분석이 이루어지고 있으나 부분적이고 단편적인 시각이 주를 이루고 있어, 인과관계에 따른 주택시장을 분석할 수 있는 시스템적 논리의 필요성이 대두되고 있다. 따라서 본 연구에서는 주택의 수요와 공급에 의해 결정되는 주택시장의 기본 원리를 바탕으로 시스템 다이내믹스(System Dynamics)를 이용한 주택 시장 작동 원리를 작성하여, 내 외부 환경변화에 따른 주택 시장의 영향을 파악할 수 있는 기본 모형을 구축하고자 한다.

The problem of selection among competing models has been a fundamental issue in statistical data analysis. Good fits to data can be misleading since they can result from properties of the model that have nothing to do with it being a close approximation to the source distribution of interest (for example, overfitting). In this study we focus on the preference among models from a family of polynomial regressors. Three decades of research has spawned a number of plausible techniques for the selection of models, namely, Akaike's Finite Prediction Error (FPE) and Information Criterion (AIC), Schwartz's criterion (SCH), Generalized Cross Validation (GCV), Wallace's Minimum Message Length (MML), Minimum Description Length (MDL), and Vapnik's Structural Risk Minimization (SRM). The fundamental similarity between all these principles is their attempt to define an appropriate balance between the complexity of models and their ability to explain the data. This paper presents an empirical study of the above principles in the context of model selection, where the models under consideration are univariate polynomials. The paper includes a detailed empirical evaluation of the model selection methods on six target functions, with varying sample sizes and added Gaussian noise. The results from the study appear to provide strong evidence in support of the MML- and SRM- based methods over the other standard approaches (FPE, AIC, SCH and GCV).
