Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Obstructive sleep apnea syndrome (OSAS) is caused by repetitive upper-airway narrowing or collapse during sleep resulting in hypopneas and apneas. When a patient is diagnosed of OSAS with polysomnogram, he/she should receive upper airway evaluation to find the narrow site. The anatomic narrow site can be nasal cavity, nasopharynx, oropharynx, and/or hypopharynx. Surgical treatment for OSAS should be tailored to the anatomic narrow site. In this article, the authors describe surgical treatment options for OSAS.

순환유동층 석탄연소로에서 석회석에 의한 찰황반응에 영향을 미치는 CaSO_4의 환원반응에 의한 SO-2 재배출을 실험적으로 확인하고 SO_2의 재배출에 미치는 온도와 CO 농도의 영향에대해 상용 순환유동층에 적용할 수 있는 기초자료를 확보하기 위해 고정층과 순환유동층에서 층물질로 석회석과 상용 순롼 유동층 하부회를 이용하여 환원실험을 수행하였으며 CaSO_4의 환원반응에 미치는 온도와 CO의 영향을 측정 및 해석하였다. 고온조건에서 CO가 환원제로 작용하여 C_aSO_4로부터 SO_2가 재배출되는 현상을 확인하였으며 CaSO_4로부터 SO_2의 재배출은 온도와 CO농도가 증가함에 따라 증가하였다. 본 실험의 결과에 의해 온도가 증가함에 따라 석회석에 의한 탈황율이 감소하는 현상을 환원이론으로 설명할 수 있다는 것이 확인되었다. For qualitative understanding of the sulphur capture process in a circulating fluidized bed fumace, the effects of temperature and CO concentration on the reactivity of partially sulfated CaO were experimentally examined. The tests were performed in a fixed bed reactor and lab-scale circulating fluidized bed reactor. The materials used were partially sulfated domestic limestone and bottom ash drained from commercial circulating fluidized bed furnaces. The re-emission of SO_2 from partially sulfated limestone and bottom ash increases with temperature as well as with concentration of the reducing agent CO. From the results of this study, the temperature dependence of sulfation could be explained by reduction theory.

근 수 년간 클라이언트/서버 모델에서 발생하는 문제인 서버 병목 현상, DoS (Denial of Service) 공격, 그리고 시스템의 확장성에 따르는 비용 증가 등의 문제를 해결하기 위한 방법으로 P2P (Peer to Peer) 방식이 활발히 연구되고 있다. P2P 방식을 사용하는 모델은 기존의 클라이언트/서버 모델이 적용되었던 여러 분야에 이용되고 있다. 그 중 사용자간 파일 공유하는 분야에 적용된 P2P가 가장 널리 알려져 있다. P2P 파일 공유 네트워크에서 가장 중요한 이슈는 검색의 효율성이다. 검색의 효율성을 위해 제안된 가장 효과적인 접근법으로는 DHT(Distributed Hash Table)을 사용한 검색 기법이다. 이 방식에서 메시지 라우팅은 정보의 검색과 분산을 위해 사용되고, 메시지 라우팅 성능은 라우팅 Hop 수에 의해 결정된다. 그러나 기존의 접근법에서는 라우팅 Hop 수를 감소시키는 능력이 부족하다. 이를 해결하기 위해 본 연구에서는 네트워크 식별자와 노드의 그룹화에 의해 메시지 라우팅 성능을 개선하기 위한, DHT를 사용한 P2P 파일 공유 네트워크를 제안한다. 노드의 그룹화는 메시지 라우팅 Hop을 감소시키고, 한 노드 내에 많은 노드를 나타내어 확장성을 갖고 있다고 할 수 있다. 실험에는 네트워크 시뮬레이터를 사용하여 증가된 확장성과 성능의 개선을 보였다.

This study exploratory examined the relationship between auditory images and clothing style images of young consumers by their personality types, sex and clothing interest. A questionnaire was developed to measure auditory images, clothing style images, personality types, clothing interest and demographic variables. Scale items were adopted from prior studies on clothing self images and Myers-Briggs Type Indicator (MBTI) known to measure psychological types. 120 undergraduate students with diverse majors were the respondents of the empirical study. MBTI categorized respondents into one of 3 personality types, IFT (Introversion and Thinking or Feeling, n=23), EF (Extroversion and Feeling, n=73) and ET (Extroversion and Thinking, n=24). ANOVA results indicated that, among 13 auditory images measured in the study, rational, self-confident and social images were significantly different across three personality type groups. Overall, ET group showed higher level of the the auditory images. Among clothing style images, social images were significantly different. IET group showed significantly lower level of social images. In addition, respodents' age and level of clothing interest influenced auditory and clothing style images. Correlation coefficients indicated that there were significant relationships between most auditory and clothing style images included in the study except for the self-confident image.

The use of advanced electronic security system is growing quickly to protect properties and life. However, customers cannot select appropriate configuration of the system because there are no objective evaluation methods to measure the security ability of the system. Furthermore, the system suppliers cannot propose quantitative value of security ability of the system. This study suggests an objective evaluation and selection method that customers and suppliers can use to base his or her decision when choosing the most appropriate configuration of the system. Our method identifies 6 characteristics and 20 sub-characteristics of the electronic security system, calculates their weights, and decides the best configuration. We use AHP(Analytic Hierarchy Process) to assign the weights of characteristics. Finally, this paper gives an example to compare four alternative configurations of the system.

Rheumatoid arthritis frequently involves the cervical spine and may lead to neurologic impairement. However, direct involvement of CNS structures by inflammatory cells has been reported infrequently. The prevalence of this complication of rheumatoid arthritis is unknown. Inflammatory CNS involvement in rheumatoid arthritis reportedly occurs in the setting of longstanding, active, erosive articular disease and is accompanied by extracranial and extraspinal nodules and vasculitis. This is diagnosed by radiologic finding of CNS nodules or meningeal thickening and by biopsy or autopsy. Treatment with corticosteroid, cytotoxic agent or surgical decompression is helpful. But the majority of patients die within several months of onset of neurologic symptom. Recently, we experienced a case of pachymeningitis caused by rheumatoid arthritis, which resolved repeatedly with azathioprine treatment.

To find out how relative short-dated reductions of the weight affect the physical strength of the boxers in each weight, we selected 27 superior boxers representing a college, made them reduce their weight for three days, and made a comparative analysis of changes in their physical strength during the reduction period by measuring it every day. As a result, we made a conclusion as follows. 1.The grips and leg strength of bantamweights and flyweights were reduced remarkably (p<.01, p<.001) after reduction, but in the other sides remarkable changes were not found. 2.The back strength of lightweights was increased very much after reduction (p<.001), but the other sides were not changed remarkably. 3.The leg strength of welterweights was reduced remarkably after reduction (p<.01), and the reaction time of the whole body was shortened (p<.001), but the other items were not changed especially. 4.The back strength of middleweights was increased very much (p<.01), and the reaction time of the whole body was shortened. But special changes were not found in the other sides. 5.The leg strength and arm strength of heavyweights were reduced much more than before reduction (p<.01, p<.05), and the reaction time of the whole body was shortened remarkably. But the other sides were not especially changed.
