Advances in individual genome sequencing technology and next generation sequencing technology have allowed for widespread research of human genome, which would give us opportunities not only to change our focus from the experience-based Korean medicine including typology and Sasang constitution to the evidence-based Korean medicine but to provide effective tailored medical care and Tang theory.

Semiconductor diode detectors coated with neutron reactive material are presently under investigation for various uses, such as remote sensing of thermal neutrons, fast neutron counting, and thermal neutron radiography. Theory indicates that single-coated devices can yield thermal neutron efficiencies from 4% to 11 %, which is supported by experimental evidence. Radiation endurance measurements indicate that the devices function well up to a limiting thermal neutron fluence of $10^{13}/cm^2$, beyond which noticeable degradation occurs. Thermal neutron contrast images of step wedges and simple phantoms, taken with dual in-line pixel devices, show promise for thermal neutron imaging detectors.

By taking a bottom-up "library in the life of the user" perspective rather than a top-down "user in the life of the library" perspective, this paper uses anecdotal evidence from the past and near present to examine the multiple roles the U.S. public library plays and has played as public space in the everyday lives of its patrons. By harnessing "public sphere" theory discussed in Jurgen Habermas's THE STRUCTURAL TRANSFORMATION OF THE PUBLIC SPHERE (1989) and by the examining the rich literatures on civic life and institutions that have evolved from it, the author argues that Library and Information Studies discourse has to expand its scope to include research and analysis of "library as place" from a user's perspective if it hopes to develop a deeper understanding of what the public library does for means to members of the communities in which they reside.

This paper discusses the economics of skyscraper construction in Manhattan since 1990. First the paper reviews the economic theory of skyscraper height. Next it documents the frequency and heights of skyscraper construction in the last 25 years. Then the paper reviews the relative movements of office rents, condominium prices, and construction costs. Statistical results suggest that the resurgence of Manhattan's skyscraper construction is being driving by the rise in the average price of apartments, and is not being driven by rising office rents or falling construction costs. Statistical evidence shows that the height premium has not been rising over the last decade. Developers have been purchasing air rights (and bidding up the prices) in order to satisfy the demand for supertall buildings. In the next five to ten years, Manhattan is likely to see over thirty 200-meter or taller buildings, as compared to only four since 2010.

In this paper, a conceptual framework of a new concept of protectability is proposed, which indicates the protection level of the system. Evaluation attributes have been identified and a hierarchical evaluation model has been established. Dempster-Shafer Theory of Evidence is applied in combining multiple uncertain judgements to produce an aggregated evaluation.

본 논문은 생산성 수준과 생산성 성장에 대한 노동조합의 효과를 분석한 연구문헌에서의 이론과 실증 연구결과들을 조사 분석한 것이다. 노동조합과 생산성 수준 및 생산성 성장의 관계에 대한 이론과 연구결과들이 다양하기 때문에 노동조합이 생산성에 미치는 효과의 방향이나 크기에 대해서는 결론적으로 단언하기는 어렵고, 결국 적절한 모형과 자료를 가지고 실증분석을 해봐야 알 수 있는 문제이다.

Building on the DC interaction model between a parent company and its spin-offs, we examine that a dyadic relationship can be differentiated within the functions of space, motivation, and time. We investigate that these three factors encompassing the parent-spin-off DC relationship can be applicable to both linear(i.e., geographic proximity and low spin-off CEO's salary is positive) and nonlinear(i.e., too much frequency of new spin-off creation is as harmful as too little) effects on determining the performance of spin-off firms. The direction of causality is underpinned by social capital, human capital, and compensation-activation theory rather than by the normal consequences of previous empirical research. Further, our results suggest the overlap between DC and entrepreneurship; namely, spin-off firms create, learn, and exploit opportunities through a reconfiguration of parent DC so that DC establishes itself as a key concept in the entrepreneurship domain.

Idiopathic Parkinson's disease (IPD) represents a common neurodegenerative disorder. While epidemiological studies have suggested a number of risk factors including age, gender, race, and inherited disorder, the cumulative evidence supports the view that environmental or occupational exposure to certain chemicals may contribute to the initiation and progress of Parkinsonism. More recently, clinical and laboratory investigations have led to the theory that dysregulation of iron, an essential metal to body function, may underlie IPD by initiating free radical reaction, diminishing the mitochondrial energy production, and provoking the oxidative cytotoxicity. The participation of iron in neuronal cell death is especially intriguing in that iron acquisition and regulation in brain are highly conservative and thus vulnerable to interference from other metals that bear the similar chemical reactivity. Manganese neurotoxicity, induced possibly by altering iron homeostasis, is such an example. In fact, the current interest in manganese neurotoxicology stems from two primary concerns: its clinical symptoms that resemble Parkinson's disease and its increased use as an antiknock agent to replace lead in gasoline. This article will commence with addressing the current understanding of iron-associated neurodegenerative damage. The major focus will then be devoted to the mechanism whereby manganese alters iron homeostasis in brain.

The early studies indicated that the firm with monopoly power is likely to engage in X-inefficiency such as a managerial slack. The reflection of the X-inefficiency theory has led to the issue that the public sector may be more inefficient than the private sector. In Korea like other many countries the electricity gas water service which can be considered as natural monopoly have been provided mostly by the public sector. In order to provide the empirical evidence to the argument that the public sector may be more inefficient than the private sector this paper estimated the four types of Solow residual which is called the total factor productivity in the electricity gas water service industry with the associated empirical model and compared its productivity with one in the manufacturing industry. The empirical results do not support the argument that the public sector may be more inefficient or less productive than the private sector.
