메시지 처리기란 클라이언트들로부터 수신된 다양한 포맷의 메시지를 수신 메시지 별 쓰레드를 생성하여 처리하고 그 결과를 목적지로 전달하는 서버 소프트웨어를 말한다. 본 논문에서는 SEDA(The Stage Event Driven Architecture) 구조의 메시지 처리기에서 각 수행함수가 CPU 또는 IO bound 특성을 가질 수 있다는 점에 착안하여, 수행 함수 별 특성을 고려해 쓰레드를 각 코어에 매핑하는 FC-TM(Function Characteristic aware Thread Mapping) 기법을 제안하였다. 본 논문에서는 메시지 처리에 필요한 각 수행함수의 특성이 정적인 것으로 가정하였다. 따라서 수행 가능한 함수를 미리 프로파일링(profiling)하여 특성을 분석한 후, 실제 수신되는 메시지에 따라 단위시간 당 처리량(throughput)이 최대가 되도록 쓰레드를 매핑하였다. 성능 평가 결과 IO bound한 함수가 특정 비율 이상 있을 경우, 기존 연구보다 단위시간당 처리량이 최대 72%까지 증가하였다.

Choosing to See: A Framework for Equity in the Math Classroom is a book intended to be a practical tool for teachers to build empowering mathematics classrooms for their students from marginalized groups. Pamela Seda and Kyndall Brown provide concrete guidance using seven key principles, the ICUCARE (pronounced "I See You Care") Equity Framework, to provide a pathway for teachers for how to meaningfully make their classrooms a more equitable space for all students.

After the rapidly changing business management environment and financial crisis, high prices and domestic recession in Korea posed threats to the business survival of small and medium enterprises (SMEs). This paper looks at the potential of micro business owners for sustainable development: those who have a spirit of entrepreneurship and the potential to be a hidden champion. Our study of micro business values uses structure equation modeling by LISREL. We have done so in order to understand the foundation of management innovation and success model of micro enterprise by increasing the entrepreneurship and management performance relationship analysis. A micro-enterprise is a type of small business, found only in Korea, often registered as having ten or fewer employees. We examine the successful type of hidden champions and the influence of entrepreneurship on start-ups in business. As compared to past research on the SME entrepreneurship, this study segments small businesses even further. Small business entrepreneurship was classified into three forms that are most appropriate for the Korean situation today: innovation, risk-taking, and pro-activeness. This research is meaningful as it is Korea's first empirical analysis on four business types: wholesale and retail sales, food and lodging business, service business, and manufacturing business. Thus far, research on small business entrepreneurship was carried out using small-scale investigative analysis. However, this research attempted to develop a model that can explain a cause-effect relation of the motivational level when it comes to the difference of entrepreneurship by each business type and small business start-up success factors. Various conceptual and operational definitions could be developed in a diverse and precise manner. Independent variables that are related to the success of small businesses can be developed additionally to examine the success factors related to the systematization in detailed manner. The research showed that the innovation, risk-taking and pro-activeness of the manifested difference in the degree of perception depending on the type of small businesses. Among the four business types, the ones that manifested the highest successful start-up rates were food, service, wholesale and retail sales and manufacturing. Results after conducting the regression analysis are shown on, which proves that the small business entrepreneurship exerts direct effect on the financial management performance of small businesses. In other words, small business entrepreneurship exerts a positive effect on the small business financial success and management performance. The R² value is 0.61. It is possible to know that the perception of systematization and variables on attitude explains the 61% of the success for small self-employed businesses management performance. We define start-up key factors that are helpful to achieve internal growth of firms by finding business survival strategies. The results also focus on Korean government policy for micro enterprise and small business support.

Pajoohesh introduced the concept of k-metric spaces and Hiltzler and Seda defined the concept of metric-like spaces. Recently, Kopperman and Pajoohesh proved a fixed point theorem in complete k-metric spaces for a Lipschitz map with bound. In this paper, we prove a fixed point theorem in complete metric-like spaces for a Lipschitz map with bound.

Let R be a prime ring with center Z and characteristic different from two, U a nonzero Lie ideal of R such that $u^2{\in}U$ for all $u{\in}U$ and $d$ be a nonzero (${\sigma}$, ${\tau}$)-derivation of R. We prove the following results: (i) If $[d(u),u]_{{\sigma},{\tau}}$ = 0 or $[d(u),u]_{{\sigma},{\tau}}{\in}C_{{\sigma},{\tau}}$ for all $u{\in}U$, then $U{\subseteq}Z$. (ii) If $a{\in}R$ and $[d(u),a]_{{\sigma},{\tau}}$ = 0 for all $u{\in}U$, then $U{\subseteq}Z$ or $a{\in}Z$. (iii) If $d([u,v])={\pm}[u,v]_{{\sigma},{\tau}}$ for all $u{\in}U$, then $U{\subseteq}Z$.

Aspergilloma of the maxillary sinus is considered rare in immunocompetent patients, but a considerable increase has recently been seen in the incidence of reported cases. Dental procedures involving the antral region are thought to predispose individuals to this form of aspergillosis. Because aspergilloma shares similar clinical features with other sinus pathologies, its diagnosis may be delayed. Thus, an early diagnosis confirmed by a histopathological examination plays a crucial role in the adequate management of aspergilloma. This article provides a concise review of the reported cases of aspergilloma associated with dental procedures and reports 2 new cases of aspergilloma in middle-aged female patients, with a presentation of their cone-beam computed tomographic findings.

The aim of this study was to investigate the effect of total polymer concentration on the chemical structure, morphology of pores, porosity, swelling ratio, degradation of gelatin-poly (vinyl alcohol) (Gel-PVA) cryogel scaffolds. Porous cryogels were prepared with cryogelation technique by using glutaraldehyde as a crosslinker. Functional group composition of cryogels after crosslinking was investigated by Fourier Transform Infrared (FTIR). The morphology of cryogels was characterized via scanning electron microscopy (SEM) and porosity analysis. All of the cryogels had a porous structure with an average pore size between $45.58{\pm}14.28$ and $50.14{\pm}4.26{\mu}m$. The cryogels were biodegradable and started to degrade in 14 days. As the polymer concentration increased the swelling ratio, the porosity and the degradation rate decreased. Spongy and mechanically stable Gel-PVA cryogels, with tunable properties, can be potential candidates as scaffolds for tissue engineering applications.

본 연구는 상권을 동태적관점에서 상권을 구성하는 업종중심특성과 상권고객인 유동인구중심특성의 적합도를 비교함으로써, 상권 활성화 방안을 모색하는데 목적을 두고 있다. 천안시에 소재하는 천안역상권, 두정동상권, 신부동상권의 업종데이터와 유동인구데이터를 분석하여, 기간경과에 따른 업종과 고객중심특성변화를 분석하여 정책적시사점을 제시하고 있다. 상권에 대한 선행연구들은 동태적 관점에서의 연구가 아닌 특정시점에서의 연구로 한정되어 있으며, 상권쇠퇴요인과 상권 활성화 요인의 대부분이 도심기능쇠퇴에 따른 도심기능 활성화처럼 서로 대응관계에 놓여있다. 본 연구에서 제시하는 지역상권 활성화 방안으로는 상권데이터관리체계구측과 획일적 활성화정책이 아닌 상권특성별 목표고객과 유입고객의 일치성을 고려한 활성화전략, 상권쇠퇴지수개발 등이며, 소상공인 지원정책 목표를 지역상권 활성화와 개별점포 경쟁력 강화의 동시추진으로 확대 제안하고 있다.
