  • Reproductive behaviors have evolved through severe inter-sexual competition. We have recently described a behavior in post-mated female Drosophila melanogaster that controls ejaculate retention and sperm storage, and is a possible mechanism by which females who have mated with several partners can choose which sperm that is stored and used for fertilization. This behavior can also regulate exposure of the female to harmful effects of male SFP that are present in the ejaculate. Our study identified the neural pathway functioning in the female brain that regulates this behavior. [BMB Reports 2015; 48(5): 241-242]

  • Three groups of wethers viz. Jamunapari ♂$\times$Black Bengal ♀ (JBB), Selected Black Bengal ♂$\times$Selected Black Bengal ♀ (SBB) and Random Black Bengal ♂$\times$Random Black Bengal ♀ (RBB) of 1 year old were evaluated for pre-slaughter traits and carcass characteristics. The correlations between pre-slaughter traits and carcass traits were computed. It was found that the preslaughter weights of JBB and SBB were almost similar in yielding hot and chilled carcass as well as dressing percentage (DP). RBB wethers were lighter (p<0.05) than JBB and SBB in pre- and post-slaughter weights and also inferior (p<0.05) in DP. SBB wethers were found to produce more visceral fat compared to JBB and RBB. Other variety meats appeared erratic in yield.l. Correlations were compared by Z statistic among three genetic groups and the value of Z did not differ (p>0.05) between groups.

  • For the large-sized and post-ultra definition TFT-LCD, improved drivability is prerequisite not only for the integration of driving circuit on glass but also for the chargeability of each pixel. In order to meet required drivability, currently adopted process architecture and materials are modified for the RC delay reduction, including the drastic increase of gate bus thickness and its related solution for step coverage. We present new process architecture and material selection for the next generation TFT-LCD devices.

  • In general, stereolithography parts is not suitable for master pattern. Because of its bad surface roughness. Therefore, To reduce roughness it requires post-process that is depending on user skill and takes long time to do. This study aims to develop an expert system which can select an optimal build orientation, reduce roughness and shorten post-processing time. Genetic Algorithm was introduced for optimization. A simplified computation model was developed for real-time response. For accurate roughness estimation, mterpolation of experimental data was implemented.

  • The purpose of this study is to help the students in middle school improve their English listening comprehension by presenting effective teaching and learning techniques using animation. A good animation provides a self-contained world with language expressed in a virtual context. A few animation such as "Mulan", "The Emperor's New Clothes", and "Gulliver's Travel" are presented. The materials are primarily for English listening comprehension, enhance awareness of American culture and life-styles, and to encourage students' active role in learning English. It is suggested that their use with content-based instruction, where animation provides relevant schema background, makes language relevant and comprehensible. Practical aspects of classroom instruction are discussed, focusing on the adaption of pre-viewing, while-viewing, and post-viewing activities to the selected animation. It is concluded that careful animation selection, purposeful lesson planning, and the integration of pre-viewing, while-viewing, and post-viewing activities into the content-based lesson encourage natural language skills, especially the listening comprehension and students' interest in English.

  • Anterior set back segmental surgery has been used for shortening the period of orthodontic treatment in case of bimaxillary or maxillary protrusion. In most cases, it requires pre-operative orthodontic treatment. Through properly performed leveling and tooth aligning, the operative porcedure can be easier and post-operative occlusal stability can be increased. But it takes time for orthodontic treatment. Recently, we have been using anterior segmental surgery before orthodontic treatment and have reliable results from that. Therefore, we have to consider arch shape, curve of Spee, tooth selection to be extracted for obtaining of post-operative occlusal stability without pre-operative orthodontic treatment.

  • 본 논문에서는 클라우드 컴퓨팅 환경에서 저장공간 이주(storage migration)시에 저장공간의 읽기/쓰기 비율을 고려한 저장공간 복제 모델 선정을 위한 실험 환경을 설계한다. 기존의 저장공간 이주 모델은 가상머신과 저장공간중에 저장공간이 먼저 이주하는 선복제(pre-copy)와 나중에 이주하는 후복제(post-copy)가 있다. 이러한 복제 기법은 VM과 저장공간 이주의 필요성과 그 방법만을 제안하였으며, 성능 향상을 위한 이주 기법 선정 방법은 제시하지 못하였다. 따라서 본 논문에서는 클라우드 컴퓨팅 환경에서 다양한 스토리지의 읽기/쓰기 비율에 따른 이주 모델 선정 기법을 실험할 수 있는 시뮬레이터 설계 방법을 제시한다.

  • Patients with essential thrombocythemia (ET) can undergo laparoscopy without international precautions. This case report describes an ET with a mild increase in the platelet count that developed after laparoscopic surgery and prolonged intraperitoneal bleeding. The patient underwent intensive postoperative medical and surgical treatments until cured. Patients with ET should provide informed consent for post-laparoscopic bleeding. Surgeons should perform optimal hemostasis. Further studies are required to provide clear guidelines for both medical and surgical interventions aimed at preventing thrombo-hemorrhagic complications associated with ET. A preoperative study of platelet function and the selection of the best cytotoxic drug for the perioperative period are mandatory.

  • Atrial fibrillation (AF) is the most common arrhythmia associated with the risk of morbidity and mortality in clinical patients. AF is considered as an arrhythmia type that develops and progresses through close connection with cardiac structural arrhythmogenic substrates. Since the introduction of catheter ablation-mediated electrical isolation of arrhythmogenic substrates, cardiac imaging indicates improved treatment outcome and prognosis with appropriate candidate selection, ablation catheter guidance, and post-ablation follow-up. Currently, cardiac computed tomography (CCT) and cardiovascular magnetic resonance (CMR) imaging are essential in the case management of AF at both pre-and post-procedural stages of catheter ablation. In this review, we discuss the roles and technical considerations of CCT and CMR imaging in the management of patients with AF undergoing catheter ablation.

  • The advent of an aging society has raised the necessity for housing development to meet the growing demands of baby boomers expected to act as the main consumers in the future housing market. This study aims to identify the characteristics of apartment houses favored by baby boomers in their post-retirement plans. Based on a literature review and survey, the study is targeted at a certain baby boom generation residing in mid- sized and large-sized apartments with a floor space of more than 30 pyeong in Gangnam, Seoul. The study reveals that baby boomers favor an active post-retirement life where they can enjoy proper leisure without considerable change in daily routines, and for that reason they choose an apartment house well equipped with neighboring, convenient facilities for their post-retirement. Their housing size shows a downward tendency in response to changes in economic conditions and number of family members living together. Health-related factors such as a comfortable natural environment and greenery also play a key role in their residence selection. Their regional preference is divided into the downtown and suburbs, and thus it will be necessary to satisfy the needs of these two consumer groups in the future housing market. This study lays the foundation for offering basic materials for the development and marketing of apartment houses.
