본 논문은 재공품 재고를 줄이기 위한 방법으로서 유사성 계수법의 도입에 관하여 서술하였다. 특히 J.R.King의 이론과 Nakornchai의 ROC-2 이론을 비교 하였다. 그 결과로서 ROC-2의 이론은 적은 기계 혹은 부품에서와 같은 시스템에 사용하는 것이 유리하며 또한 기계나 부품의 그룹화가 서로 독립적으로 수렴되지 않아도 된다는 장점이 있다. This paper reprented that work-in-process inventory has been decreased with the application of the similarity coefficient algorithm. Especially, J.R.King's ROC and Nakornchal's ROC-2 algorithm is studied. The analyzed resuits in this paper are as ROC and ROC-2 algorithm have an adventage that it can be used in production system which has many machinary and component and an arbitrary threshold value should be define and many grouping are being performed independently.

As the size of camera modules is decreasing and as the computing performance of portable devices is improving, taking photos has become a part of daily life. However, existing photo management programs and products that manage such photos still require extensive user effort to facilitate the sharing and browsing of images. It is especially difficult for novice users to manage and share photos. In this paper, we develop a round-robin concept-driven user preference feedback mechanism for achieving direct photo sharing, instant display, and easy management using optimized user controls and user preference-driven classification. Compared with commercial photo management systems, our proposed solution provides new features: optimized user controls, direct sharing and instant display, and user preference feedback driven classification. These new features boost the round-robin concept-driven user preference feedback. This paper proposes a photo finder that automatically searches for photos in storage spaces or cameras. The proposed photo finder relies on user preference feedback to share photos by leveraging user preferences, and the round-robin connection transmits photos to the family``s digital photo frame or web album by arbiter. The proposed method saves time and spares users the effort required for photo management. Moreover, this method does not merely direct photo sharing and simple photo management, but it also increases the satisfaction level of users viewing the photos.

본 논문은 현실감 있는 윷놀이 게임을 만드는데 그 목적이 있다. 현실감 있는 윷놀이란, 사용자가 실제 윷을 던지는 행위를 입력으로 사용하고, 음성으로 말을 조종함으로써 컴퓨터와 사람간에 자연스러운 인터페이스를 구현하는데 그 목적이 있다. 또한 애니메이션 제작에 사용되는 플래시를 이용하여 사용자 인터페이스를 구성함으로써 사용자가 보다 쉽고 재미있게 게임에 몰입할 수 있도록 한다. 본 논문을 구현하기 위해 적외선센서와 가속도센서, 지그비 모듈, 그리고 이들 센서를 제어하는데 사용할 마이크로 프로세서를 이용하여 게임에 사용되는 윷을 만든다. 적외선센서는 윷의 앞/뒷면 상태를 측정하는데 사용되고, 가속도 센서는 윷의 3 차원상에서의 위치를 파악하는데 사용된다. 윷의 위치와 앞/뒷면 상태는 지그비 모듈을 이용하여 컴퓨터에 전달되고, 사용자의 음성 명령으로 자신의 말을 움직일 수 있다. 본 논문의 의의는, 현재 널리 사용되는 센서, 통신, 시각화 기술과 음성인식 기능을 결합하여 보다 현실감 있고 자연스러운 사용자 인터페이스를 만드는데 있다. This paper proposes make sense for the real interaction in playing Yut games. In order to make the practical interface, uses the user input with user throws a Yuts and make a move on the game board using voice commands. And build a user interface use the Flash program. For this research implementation make a digital Yut-makes Yut with Infrared, accelerator sensor, ZigBee module and uses the processor-and using voice recognition software. Digital Yuts connect to host PC with ZigBee communication. This research focus on make natural user interaction between human-computer with combine widely used sensor, animation program, and communication protocol.

The purpose of this study is to analyze the problems of land and sea breeze model experiment that has presented in 5^th grade curriculum in chapter “Weather and our lives” and makes better model simulation so that learners can have better and more effective way to study it. To survey the opinions from dedicated teachers about land and sea breeze model experiment, we produced the survey through interview with science exclusive teacher from M elementary school. An elementary science education expert, 3 men of science EdD modified and complemented survey and started Delphi survey to 12 science teachers who have career teaching more than 3 years. The problems found in this survey were `one heat bulb, short heating time, small temperature difference of water and sand, lack of class time, empty space between sand and water, back of transparent boxes, little amount of scent and the location of the it` etc. But the most of all, it is hard to see the successful result of the experiment. Based on these kinds of investigations, and lots of trial and error, redesigned the new model experiment that has the most similarity to the real one and high probability of success. According to this, it was able to see the smoke forms horizontal movement along the sand and the smoke goes in one circulation cycle. through this experiment, we made a conclusion that although those scientific experiments in textbook were developed through lots of considerations of expert, to consider the aspect of consumer, it needs to reach the educational agreement about simulation experiment so that It can lead to successful experiment and high quality education.

The attraction of using expert system in operator support systems for modern plant is that it offers a way of dealing with the problem of information overload that can occur during a severe disturbance at a modern industrial plant. During such a disturance the volume of information presented to operators may be such that they are unable to decide quickly what, is important and what is not. Therefore, arriving at a correct diagnosis of the initiatling fault may be delayed. An expert system operator support system is a means of focusing attention on what really matters and cutting out the rest. This paper presents the development of prototype expert system which detect the fault part, machine, system and decide action priority. This prototype expert system has 6 sub-system which is Interface Manager, Decision Maker, Inference Engine, Knowledge base, Simulatio, and D.P System (Diagnosis and predictor).

Alternative Splicing for Improving Abiotic Stress Tolerance and Agronomic Traits in Crop Plants

Kim Seojung,Tae‑Houn Kim 한국식물학회 2020 Journal of Plant Biology Vol.63 No.6

Most eukaryotic genes undergo various post-transcriptional processing events before being translated into proteins. Alternative splicing (AS) is one such event and is an essential mechanism in post-transcriptional gene regulation that allows multiple mRNA variants to be expressed from a single pre-mRNA, thereby expending the functional capacity of a gene as well as the organismal complexity. With the advancement of next-generation sequencing technologies, extensive transcriptomic resources in plant species have determined crucial roles of AS in the regulation of developmental processes and adaption to environmental stresses. We review here recent studies of AS events and splicing factors that specifically affect abiotic-stress tolerance in crop plants, including other agricultural traits. Understanding how alternative splicing modulates plant development and abiotic-stress responses may provide new insights for improving the environmental fitness and productivity of crop plants.

Steel structure has several advantages such as flexibility in space layout, structural stability, durability, and ease of fabrication. However, steel structure has higher story height and smaller gross floor area than reinforced concrete structures, since the slabs are constructed over the steel beams. The reinforced concrete structure that uses wide beams has shorter story height, but requires complex construction processes and long construction duration. This research presents the iTECH(Innovative, Technical, Economical, and Convenient Hybrid) system that has the advantages of both steel and reinforced concrete structures. The system is a composite beam that consists of asymmetric steels with web opening and in-situ concrete. The system was applied to the selected 2-story building to verify its practical use. The building was constructed with short story height, small material quantity, short construction duration, and fine workability and structural stability. Therefore, it is concluded that the proposed system is beneficial in many aspects, and can be readily applied to several types of buildings such as high-rise residential building, office buildings, and long span structures.
