Synchronization of temporal constructs in distributed multimedia systems with controlled accuracy
Son Son, Agarwal

With the inception of technology in communication networks such as ATM, it will be possible to run multimedia applications on future integrated networks. Synchronization of the related media data is one of the key characteristics of a multimedia system. In this paper we present a scheme for synchronization of multimedia data across a network where the accuracy of detecting asynchronization and predicting the future asynchrony is variable and can be tailored to the intended application. The multi

MRDB: a Multi-user Real-time DataBase testbed
Son Son, Young‐Kuk Kim, Beckinger

Transactions in real-time database systems should be scheduled considering both data consistency and timing constraints. In addition, a real-time database must adapt to changes in the operating environment and guarantee the completion of critical tasks. The effects of scheduling decisions and concurrency control mechanisms for real-time database systems have typically been demonstrated in a simulated environment. In this paper, we present a functional real-time relational database manager, calle

본 연구에서는 도시지역의 침수해석시간 단축을 위하여 도로네트워크를 활용한 2차원 침수해석의 효용성을 살펴보고자 한다. 이를 위하여, 세가지의 모의조건을 설정하였으며, Case 1은 도로만 침수가 발생하는 조건, Case 2와 3는 도로 및 건물지역 모두 침수가 발생하는 조건이다. 따라서 Case 1은 수치지형도로부터 추출한 도로네트워크를 따라 격자를 구성하였으며, Case 2와 3는 각각 전체 연구유역에 대해 정형격자 및 비정형격자로 구성하였다. 각 조건을 2010년 9월 21일 발생한 집중호우로 인하여 침수피해가 발생한 삼성배수분구에 적용하였다. Case 2와 3의 정확도 및 계산시간을 Case 1과 비교함으로써, 본 연구에서 제안한 도로네트워크를 활용한 2차원 침수해석기법의 효율성을 검증하였다. 해석 결과, 총 침수해석시간은 Case 1, Case 2, Case 3 순으로 빨랐으며, 각 조건별 도로영역 내 침수 적합도는 85% 이상을 보여주었다. 그리고 건물 영역에 대한 침수는

A Language-Specific Physiological Motor Constraint in Korean Non-Assimilating Consonant Sequences

말소리와 음성과학

This paper explores two articulatoiy characteristics of inter-consonantal coordination observed in lingual-lingual (/kt/, /ks/) and labial-lingual (/pt/) sequences. Using electromagnetic articulometry (EMMA), temporal aspects of the lip movement and lingual movement (of the tongue tip and the tongue dorsum) were examined. Three sequences (/ks/, /kt/, /pt/) were investigated in two respects: gestural overlap in C1C2 and formation duration of coronals in C2 (/t/ or /s/). Results are summarized as

Feasibility Calculation of FaSTMECH for 2D Velocity Distribution Simulation in Meandering Channel

Journal of the Korean Society of Civil Engineers

하천의 흐름장을 모의하는 수치모형들은 연구 및 실무에서 다양한 목적의 유동해석에 광범위하게 활용되어오고 있다. 그러나, 수치모의 결과에 대한 검증은 현장 실측자료의 한계로 수리모형실험이나 매우 제한된 현장자료를 기반으로 수행되어 보다 정밀한 검증이 요구되어 왔다. 특히, 사행하천과 같이 기하학적 구조 및 흐름이 복잡한 형태를 갖는 경우는 수치모형이 얼마나 정확한 유속분포 모의를 할 수 있는지 알기 힘들었다. 최근, 초음파도플러유속계(ADCP) 등 최신 현장 계측기기의 발달로 하천 흐름의 정밀한 유속 및 하상 자료를 매우 효율적으로 측정 가능하게 되었다. 따라서, 기존 수치모형들을 실제 하천에서 공간적으로 정밀하게 측정된 유속자료를 기반으로 성능을 검증할 수 있는 기술적인 기반이 마련되었다고 할 수 있다. 이에 본 연구에서는 사행하천에서 정밀하게 측정된 ADCP 유속 자료를 기반으로 최근 국내에 도입된 FaSTMECH 모형을 대상으로 사행하천의 수위와 유속 분포 모의 결과를 검증하였다

Studies of application of artificial ground freezing for a subsea tunnel under high water pressure - focused on case histories -

Journal of Korean Tunnelling and Underground Space AssociationOA

본 연구는 고수압 해저터널의 차수를 위한 동결공법 적용성 평가를 위해 국내 적용사례가 없는 동결공법의 해외 시공사례를 조사하였으며, 지반 동결공법에서 보편적으로 사용하는 냉매인 브라인(brine)과 액체질소(<TEX>$LN_2$</TEX>)에 대한 분석을 수행하였다. 고수압 조건의 해수는 순수한 물에 비하여 어는 점이 더 낮기 때문에 지상에서보다 동결시간이 더 길 수 있고 해저터널과 같이 폐쇄된 공간에서의 적용 시 냉매는 안정성을 확보할 수 있어야 하고 공기 단축이 가능해야 한다. 브라인은 재사용이 가능하고 독성이 적어 인체에 미치는 영향이 적으나, 동결에 상대적으로 장시간 필요하고 동결장비가 복잡한 특징을 가지고 있으며, 액체질소는 냉매의 재사용이 불가하며 기화 시 공기 중 질소농도 증가로 질식의 위험성이 있으나, 상대적으로 동결시간이 짧으며, 동결장비가 간단한 특징을 가지고 있는 것으로 파악되었다. 또한 향후 추가적인 연구가 필요한 해저터널 연결구 및 막장면 주변 지반에 대한 동

An exploratory study on entry-level male and female employees’ organizational adaptability

대한경영학회지

Although retaining talent is the key to strengthening a corporation’s competitiveness, the turnover rate for entry-level employees because of corporate maladjustment is increasing. However, due to insufficient preceding studies on organizational adaptability, it is difficult to examine the troubles entry-level male and female employees face when adapting to an organization. This study uses mixed methods to compare the differences in organizational adaptability between male and female entry-level

말소리와 음성과학

In this study, we aim to describe kinematic characteristics of Korean /l/-flapping in two speech rates (fast vs. comfortable). Production data was collected from seven native speakers of Seoul Korean (four females and three males) using electromagnetic midsagittal articulometry (EMMA), which provided two dimensional data on the x-y plane. We examined kinematic properties of the vertical/horizontal tongue tip gesture, the vertical/horizontal (rear) tongue body gesture, and the jaw gesture in an /
