According to statistics of the Ministry of Health and Welfare at 2010, patient of breast cancer has been increasing constantly. Radiation therapy is method of treatment for breast cancer. Generally, radiation therapy technique of breast cancer is opposing 2 port. And It is using real wedge, dynamic wedge, FiF(Field in Field) technique, ISC(Irregular Surface Compensating) technique for uniformity dose in breast tissue. But each patient applied different method of surgery. In this study, It is to evaluation the usefulness of radiation therapy technique at each surgery technique. Subjects are tissue loss after breast conserving surgery, non tissue loss after breast conserving surgery, and mastectomy. Each subject applied 4 techniques of radiation therapy. Measurement tool used CI(Conformity Index), HI(Homogeneity Index), and QOC(Quality of Coverage) at suggest RTOG(The Radiation Therapy Oncology Group). Case of tissue loss is useful dynamic wedge technique. Case of non tissue loss is useful FiF technique. Case of mastectomy is useful ISC technique. In the future, this study would use to selection standard of radiation therapy for breast cancer surgery. And selection standard would require additional analyzes of normal organ.

Cockroaches are insects of the order Blattodea, sometimes also called Blattaria, of which about 30 species out of 4,600 total are associated with human habitats. About four species are well known as pests. Among the best-known pest species are the American cockroach, Periplaneta americana, which is about 30 mm long; the German cockroach, Blattella germanica, about 15 mm long. We researched growing condition of in-vitro(temperature and humidity) for P. americana and B. germanica. The cockroach is divided in three sections; the body is flattened and broadly oval, with a shield-like pronotum covering its head. A pronotum is a plate-like structure that covers all or part of the dorsal surface of the thorax of certain insects. They also have chewing mouth parts, long, segmented antennae, and leathery fore wings with delicate hind wings. The third section of the cockroach is the abdomen. We measured size of head, abdomen, and body length during differential stages. Also, we checked number of egg, size of egg, hatching rates, period of former laying eggs, and laying periods etc.

After firstly identified sex pheromone components of Bombxy mori, those of many insect pests were synthesized by organic chemistry methodology. These synthesized components were used for monitoring, mass trapping, and mating disruption during five decades. For identification of pheromone biosynthesis mechanisms and control to many pests bring to serious damages also were proceeded. The transcriptome analysis from pheromone glands by Next Generation Sequence (NGS) showed many genes and pathway involved on sex pheromone biosynthesis.. The two main genes involved on production of acetate and alcohol, and aldehyde from fatty acid, fatty acid desaturase and fatty acid reductase (FAR) were identified and functional characterized via gene introduction to Brewer’s yeast Saccharomyces cerevisiae. This S. cerevisiae now used as a mediator as well as cell factory for sex pheromone producing. Recently, One group was published that the plant factory for producing via genetically modified plant (tobacco, Nicotiana benthamiana) as a step of semisynthetic preparation. These trials will be suggest that firstly, the possibility of yeast as a molecular toolbox to produce pheromone components and secondly, a novel and cost-effective way of producing moderate to large quantities of pheromones with high purity and a minimum of hazardous waste.

The hydraulic equipments has a high utilization in the many works such as the excavation, planation and crane works in the construction sites. They are an essential equipments in the construction site and the loading & unloading works of the large size objects. In the many parts which are composed of the hydraulic equipments, the main control valve(MCV) is the core of the equipments. The hydraulic energy from the pump controls the direction and the rate of flow and supply the pressure energy to the some actuators by MCV. In spite of the domestically producing of the common control valves, the MCV which used to the domestic equipments is imported the whole quantity. In this study, it is to reverse-engineer the MCV as the first step in the development of the MCV. To analyze the notch of the spool and the flow path and to apply the formula technique, we try to realize the optimal modeling of the MCV.

Black Friday, a biggest holiday shopping season in the United States, has been regarded as a great opportunity that fashion retailers can dramatically increase their sales. However, there has been a lack of attention to consumers' shopping experiences on Black Friday from the consumer perspectives. The objective of this study is to explore consumer shopping experiences on Black Friday, in terms of consumer responses toward the experiences, shopping values, and any possible factors influencing the experiences. The method of critical incident technique was used with 198 critical incidents extracted from 165 responses of university students in the United States. As results, the shopping experiences on Black Friday were categorized into positive vs. negative shopping experiences. After that, the positive and negative experiences were respectively divided into two common themes: utilitarian shopping value vs. hedonic shopping value. In addition to the common themes, 12 categories were also emerged. Among positive experiences, utilitarian shopping experiences includes two categories of off-price shopping and shopping for expensive products, whereas hedonic shopping experiences includes three categories of impulse buying, holiday atmosphere, and shopping for the latest or luxury brand products. Among negative experiences, utilitarian shopping experiences includes four categories of modest discounts, out of stock, time-consuming queues, and fatigue of holiday shopping, while hedonic shopping experiences includes three categories of crowded environments, compulsive buying, and poorly managed stores. In conclusion, it is notable that consumer can undergo negative as well as positive shopping experiences on Black Friday. Implications and suggestions are also discussed.

This paper studies how the continuity and uniformity are achieved in the 16th century polyphony through the imitation technique and cadential formula. Usually imitation technique is needed for the beginning and cadence for closing in the polyphony texture but these two are overlapped in inner cadences thus producing meshed opening and ending in progressions. Cadence is a device for bringing a pause or a close in a section. In spite of that inner cadences should produce a double effect of termination and continuity before the final cadence in order to show coherence. In this sense intensity is important in inner cadences. Imitation is a tool for repetition. Imitation in perfect interval according to hexachord system confrims the fact that “a melody” is repeated by several voices in different register. Sharing a melody denotes uniformity while voices beginning in various time difference represent continuous flow of time. Imitation happens at the beginning of a phrase but it overlaps with the cadence of the previous phrase creating a continuity naturally between two phrases.

본 연구에서는 고추의 수분스트레스 반응을 최적으로 계측할 수 있는 알고리즘을 개발하기 위해 초분광 단파 적외선 영상기술을 적용하였다. 수분스트레스에 노출된 고춧잎의 단파적외선 분광영상을 획득하고 ANOVA 분석을 이용하여 수분스트레스 반응을 가장 잘 반영하는 파장영역을 선정하였다. 고춧잎의 단파적외선 초분광 영상을 이용하여 ANOVA 분석을 수행한 결과 수분스트레스 판별을 위한 최적 파장은 1449nm으로 물분자의 광 흡수 영역대와 거의 일치하였다. 최적 파장에서의 고춧잎 상대반사값을 가우시안 회귀분석을 통해 정상군과 토양흡착수압이 −20kPa과 −50kPa일 때의 스트레스군을 구분할 수 있는 임계값을 계산하고 이 값을 기준으로 단파적외선 영상을 이진화하여 수분스트레스 반응을 판 단할 수 있는 최종영상을 구축하였다. 결과 영상에서 정상군과 스트레스군의 토양흡착수압이 −20kPa인 잎의 경우 스트레스 반응을 보인 픽셀이 72%이었고, −50kPa인 잎에서는 스트레스 반응을 보인 픽셀이 84%로 12%차이 가 났다. 정상군과 스트레스 강도가 다른 시료의 경우 영상의 결과가 명확히 구분되는 것으로 나타나 단파적외선 영상기술이 고춧잎의 수분스트레스 상태를 정량적으로 나타낼 수 있는 기술임을 확인할 수 있었다.

Attempts to hack online game servers and abusing problems in online games have been issues in game industry. Mobile games are famous these days thanks to the widespread of smart devices. Unfortunately, mobile games have very short life cycle. Therefore, analysis of game log data becomes more important to overcome the hacking and abusing problems in online games and extend their life cycles in mobile games. In this paper, we propose a new game log data analysis technique based on the MapReduce methodology. MapReduce is a widely used programming model for analyzing and processing Big data. Instead of processing each analysis query separately, the proposed technique processes multiple analysis queries together in a batch by a single, optimized MapReduce job. As a result, the number of queries processed per unit time increases significantly. Experiment results show that the proposed technique improves the performance significantly compared to a naive method.

수확 후 해충방제가 국내 수요 농산물은 물론이고 검역 문제를 해결하기 위한 수출용 농산물에 대해서 요구되고 있다. 특별히 유기 농산물 또는 환경친화형 재배 농산물에 대해서 메틸브로마이드와 같은 화합물을 이용한 기존의 수확 후 처리기술은 의미를 잃게 되었다. 대체 기술로서 CATTS (환경조절열처리기술)라 명명된 물리적 처리기술이 개발되어 사과와 여러 핵과류 과실을 가해하는 곤충과 응애에 적용되고 있다. 본 연구는 국내 사과 수출을 위해 수입국에서 규제하는 복숭아순나방(Grapholita molesta)을 대상으로 CATTS 처리 조건을 결정하는 데 목표를 두었다. 이 해충에 CATTS를 적용하기 위해 사과 과실에 잔류하면서 열에 높은 내성을 보이는 발육시기를 분석하였다. 열처리 조건(44℃, 20분)에서 5령 유충이 가장 높은 내성을 보였다. 환경조건(15% CO2, 1% O2)에서 기기 내부 온도가 25℃에서 46℃까지 증가하는 시기를 CATTS 가열단계로 볼 때, 이 가열 속도가 빠를수록 CATTS 해충 방제 효과가 높았다. 또한 가열단계 후 CATTS 처리 시간이 길수록 CATTS 효율이 증가했다. 특히 가열단계에서 과실 내부온도가 44℃로 이르게 하는 것이 CATTS 효율을 높이는 데 결정적이었다. 이러한 조건들을 종합하여 CATTS표준 처리기술을 결정하였으며, 이 기술은 2,104 마리의 5령을 포함한 4,378 마리 복숭아순나방 유충 피해를 받은 사과에 대해서 100% 방제 효과를 나타냈다.

Computer graphics technique with which two dimensional black and white characters used to be displayed on a monitor in the early period, has now been developed to display three dimensional color images on a mobile terminal. In particular, owing to technique growth in graphics, non-photo realistic rendering technique has grown to express non-photo realistic images as well as realistic rendering. Non-photo realistic rendering technique grows to be motion graphic technique. With the growth of motion graphic technique, it can be possible to produce various expressions and effects. This study proposes a way of turning three dimensional images into two dimensional cartoon look. Two dimensional cartoon look, a type of pictorial expression appeals to emotions, and is in great demand at advertisement, mobile and cartoon. Thus, this study not only changes three dimensional images into two dimensional cartoon look, but also numerous images can be expressible in one page by applying PIP (Picture In Picture) technique, and expressions of cartoons are to be reproduced in turning pages automatically by applying ‘page turn’ technique. Accordingly, it is believed that this content production technique can be applicable in various fields including game, advertisement, cartoons, etc.
