We propose a policy for controlling the release of raw wafers into the semiconductor wafer fabrication lines. The proposed policy exploits up-to-date factory floor information gathered by tracking systems used to calculate the time and amount of a new release to minimize mean flow times and mean tardiness while maintaining the maximum output rates of the system. Extensive computer experiments show that the proposed policy results in significant improvements for the same output rates compared to existing release rules.

한국천문연구원은 2014년 8월부터 동아시아 파트너로서 ALMA 국제 공동 사업에 참여하였고, 2015년 3월부터 동아시아천문대의 일원으로 JCMT 망원경 운영을 시작하였다. 이를 개기로 한국 천문학자들은 ALMA와 JCMT 망원경을 본격적으로 연구에 이용하고 있다. 최근에 한국천문학자들에게 ALMA 관측 자료가 전달되었고, 그 일부 자료의 분석 결과가 논문으로 편찬되었다. 또한 7개의 JCMT Large 프로그램에 많은 한국 천문학자들이 참여하여 좋은 연구 결과가 나오고 있다. 이런 시점에서 한국천문학계에 ALMA와 JCMT를 이용한 한국 연구자들의 연구결과를 알리고, 사용자의 저변을 확대하기 위해서 이 특별 세션이 기획되었다. 본 발표는 그 동안의 한국 ALMA 프로젝트와 JCMT 참여 성과에 대한 개괄적인 소개를 할 예정이다.

High-velocity clouds are flows of neutral hydrogen, located at high galactic latitudes, with large velocities ($[VLSR]{\ge} 100 km/s$) that do not match a simple model of circular rotation for our Galaxy. Numerical simulations have been performed for the last 20 years to study the details of their evolution, and their possible interaction with the Galactic disk. Here we present a brief review of the models that have been already published, and describe newly performed three-dimensional magnetohydrodynamic simulations.

This article aims at rethinking on people of Modern styles in early modern period with reference to A Large River[Dae-Ha] written by Kim Nam-cheon at 1939. Park Sung-guoen could be called to Homo Economicus, first, have maximized of self-interest in rapid changes of Korea society with loan sharking, rising to upper class in new early modern era instead of traditional nobleman. Park Hyung-geol could be said romantic guy, second, have chased romatic love consist of three elements(love-sex-marriage). But he troubled his love affairs to his family members frustrated his will because of a bastard son. It is the model of situations, Kim Nan-cheon intended to describe, that Homo Economicus became an object of envy among people in early modern society as well as the choice has been hard in conflicting between family and lover, concretizing anachronism through history of family.

Background: Emergency room doctors run into difficulties in treating injured pediatric patients because usually they fell into panic after trauma. In these situation, deep sedation with sevoflurane is fully recommendable method. The conventional way can interrupt common dental treatment procedure. Methods: In the present study, nasal cannula was used for sevoflurane deep sedation in 11 dental emergency treatment. Age ranged from 0 to 3 years old (average of 1.8 years). Results: Treatment duration was from 10 to 35 minutes (average of 16.7 minutes). Average duration of sedation was 25.5 minutes ranging from 15 to 45 minutes. Conclusions: It has advantages to use nasal cannula for sevoflurane deep sedation rather than conventional intubation; saves time and secures good operation field.

In this research, we consider an integrated manufacturing/distribution planning problem in supply chain (SC) which has non-integer time lags. We focus on a capacitated manufacturing planning and capacity allocation problem for the system. We develop a mixed binary integer linear programming (MBLP) model and propose an efficient heuristic procedure using an adaptive genetic algorithm, which is composed of a regeneration procedure for evaluating infeasible chromosomes and the reduced costs from the LP-relaxation of the original model. The proposed an adaptive genetic algorithm was tested in terms of the solution accuracy and algorithm speed during numerical experiments. We found that our algorithm can generate the optimal solution within a reasonable computational time.

과거의 모바일 광고에 대한 연구는 음성통화나 SMS, MMS 등의 활용에 따른 광고의 효과성을 연구하는 것이 주류를 이루고 있었다. 하지만, 시간의 경과 및 모바일 단말기의 발전 등에 따라 점차 예전의 모바일 광고의 형태와는 다르게 고객에게 디지털 컨텐츠, 일반 범용제품, 금융상품, 서비스 제품 등의 구매유도를 위해 메시지광고(SMS, MMS)나 고객들이 검색이나 배너, 비디오 등의 보다 다양한 광고형태를 통해 고객들로부터 기대하는 반응을 얻고자 하는 서비스로 변화하고 있다. 이에 따라, 본 연구에서는 모바일 광고가 지니고 있는 대표적 특성을 개인화, 편리성, 오락성, 경제성, 신뢰성, 유용성 등으로 분류를 하고, 이러한 모바일 광고의 특성이 모바일 광고 수신자의 수용의도에 어떠한 영향을 미치는가를 분석하며, 나아가 모바일 광고의 수용의도가 모바일 광고의 만족도에 어떠한 영향을 미치는가를 분석한다.
