The 2'-fucosyllactose (2'-FL) is the richest components in a human milk oligosaccharide. Several studies have reported that 2'-FL has beneficial effects in infants. However, there are few studies on its immune-enhancing effects. This research aimed to examine the immune-enhancing effect of 2'-FL on immunosuppression by cyclophosphamide (CCP) in ICR mice. Mice were orally administered distilled water or 0.5 mg/kg B.W. 2'-FL for 14 days. An immunocompromised mouse model was induced using CCP 80 mg/kg B.W. at 12-14 days. Using the CCP had effects on reducing their body weight, organ weight, spleen index, natural killer (NK) cell activity, and cytokines concentration and expression. This study also used concanavalin A-mediated T-cell proliferation to verify the immune-enhancing effects in the sample. Body weight, spleen index, organ weight, and cytokine levels were measured to estimate the immune-enhancing effects. The body weight at 14 days tended to increase, and the spleen weight and index significantly increased in the 2'-FL group compared to the CCP group. The NK cell activity increased in the 2'-FL group compared to the CCP group, but there was no significant difference. The concentration of interleukin (IL)-2 tended to recover in the 2'-FL group compared to the CCP group. The 2'-FL group showed a significant increase of IL-10 and IFN-gamma concentration compared to the CCP group. In addition, there was a trend of increased IL-10 mRNA expression compared to the CCP group. These results revealed that 2'-FL improved CCP-induced immunosuppression, suggesting that 2'-FL may have the potential to enhance the immune system.

LVDS에 기반을 둔 초고속 저전력 직렬 인터페이스인 SMIA(Standard Mobile Imaging Architecture) CCP2(Compact Camera Port 2) 규격을 채택한 CMOS 이미지 센서들이 개발되면서, 기존의 CMOS 이미지 센서들과 직접 연결되었던 장비들이 사용할 수 없게 되고 있다 본 논문에서는 SMIA CCP2 규격의 직렬데이터 신호를 범용 10-비트 병렬 신호로 변환하는 시스템을 제안하고. 이의 구현 방안을 제시한다. 제안한 데이터 프로토콜 변환 시스템은 de-serializer 1개와 저가의 FPGA로 구성되어 소형 PCB로 구현되어, 장비와 이미지 센서 사이를 추가 공간 없이 용이하게 접속할 수 있다. 또한 SMIA CCP2 규격에서 제시된 최대 속도인 650Mbps의 속도로 데이터를 변환하는 것이 가능하기 때문에 범용 프로토콜 변환 시스템으로서의 활용성도 매우 높을 것으로 기대된다.

The thermal margin of CANDU-6 reactor is estimated by the CCP, which is dependent on fuel channel hydraulics and the CHF of fuel bundle. This paper intents to describe the characteristics of CCP behavior for the CANDU-6 channel in which CANFLEX-NU fuel bundles are assumed to be loaded. Also, it includes the thermal margin evaluation of the CANDU-6 channel loaded with a mixed CANFLEX-NU and 37-element fuel bundles as a simulation of the partial loading of CANFLEX-NU fuel bundle in the CANDU-6 reactor. For the mixed fuel channels, the effects of axial flux distribution(AFD) on CCP were investigated by using the AFD tilted in the downstream. The CCP of CANFLEX-NU fuel bundle was found to be improved by the CHF enhancement, despite of the slight flow decrease, in case of both full and partial loading, compared with those of a standard 37-element fuel bundle.

This paper aims to analyze China's political education, which plays a role of vehicle in the Chinese Communist Party (CCP) promoting its ideological strategy, in order to figure out the utility of the CCP's ideological strategy. After Reform and Opening Up, the CCP rebuilt and reinforced political education in China according to its ideological strategy. Especially after the Tiananmen incident in 1989, the CCP made nationalism and patriotism as the core part of political education, and expanded its curriculum. Such reinforcement of political education has a advantage in maintaining the CCP's governance by creating a nationalist consensus against the western ideas. Although it can be helpful for the stability of domestic politics, it also has negative possibilities which isolate China in the global community and obstruct China's development.

The purpose of this study was to improve the sanitary management of school foodservice. A survey questionnaire was administered to 153 dietitians from elementary, middle and high schools in the Daejeon area. The questions were categorized into four fields: 'General characteristics', 'Facility and equipment set up at the schools studied', 'Performance of CCP(criticai control point)s' and 'Reasons of barriers to HACCP(hazard analysis of critical control points) implementation'. The results were as follows. Most of the subjects were the dietitians of elementary school(56.9%), were university graduates(51.0%) and were in their thirties(58.2%). The average length of their career had been 5.8 years. The average ratio of students per dietitian was 1,163. The average ratio of students per full-time employee was 124. The ratio of self-operated management was 90.2 %. The CCP7(assembling and serving) received the highest performance score, while the performance score of CCP2(management of potentially hazardous foods) was the lowest. Eighty-four percent of the surveyed school foodservices did not have pre-preparation rooms. The school foodservice operations were not well equipped with hot/cold holding equipments. Self-operated management scored higher on almost all sections(CCP1-CCP7). Contracted management scored highest on CCP8. The higher the age and career of the subject were, the higher were all the CCP performance scores. The reasons of barriers to HACCP implementation were lack of understanding of standards CCP1 and CCP2, workers' lack of cooking knowledge, and lack of information about school foodservice.

In this paper, we have presented a quantitative performance effect of CCP(Call Control Processor) when SAAL(Signalling ATM Adaptation Layer) function is distributed from CCP to SIMs(Subscriber Interface Modules) in an ATM switching system with distributed architecutre. For the performance analysis, SLAM II simulation language is used and subscriber signalling messageand inter-processor communication messages according to Q.2931 based local call processing procedure are taken into consideration in the proposed queuing network model. The results of simulation are compared with in case of processing SAAL function on CCP. It is observed that the processing utilization of CCP reach 24,000 BHCA and 25,700 BHCAwhen SAAL function load amounts to 10% and 20% of the processing time of the total message, respectively. These values shows that the processing utilization of CCP is alleviated about 7% in comparison with 2,000 BHCA in case that SAAL function is carried out on CCP. Consquently, it is shown that we have to consider seriously how to distribute the functions concerning call processing in a large cale ATM switching system architecture accomodating a number of SIMs.

본 논문에서는 고출력 증폭기 (High Power Amplifier; HPA)의 비선형 특성에 관계없이 시스템의 비트오율 (Bit Error Rate; BER) 성능을 유지하면서 동시에 효율적으로 PAPR (Peak-to-Average Power Ratio)을 감소시킬 수 있는 CCP (Companding Combined with Predistorter) 기법을 제안한다. 제안된 CCP 기법은 기존에 본 저자들이 제안한 Companding 기법이 가지고 있는 Compression 특성과 HPA의 비선형 왜곡 특성에 의해 발생되는 전송 신호의 왜곡으로 인해 나타나는 시스템의 BER 성능 열화를 보완하기 위해 Predistorter를 기존의 Companding 기법에 결합하였다. 따라서, 제안된 CCP 기법은 HPA의 비선형 특성에 관계없이 효율적으로 PAPR을 감소시킬 수 있으며 동시에 시스템의 BER 성능도 유지시킬 수 있는 PAPR 감소 방식이라고 할 수 있다. 모의실험 결과, 제안된 CCP 기법은 TD (Total Degradation) 측면에서 Predistorter를 고려한 Clipping 기법과 Wang이 제안한 Companding 기법에 비해 모든 변조방식에서 가장 낮은 TD 성능을 나타내고 있음을 확인하였다.

In this paper, an improved lower bound on the burst-error correcting capability of th ecyclic product code is presented and through the analysis of this new bound clustered cyclic product (CCP abbr.)code is proposed. The CCP code, to improve the burst-error correcting capability, combines the idea of clustering and the transmission method of cyclic product code. That is, a cluster which is defined in this paper as a group of consecutive code symbols is employed as a new transmission unit to the code array transmission of cyclic product code. the burst-error correcting capability of the CCP code is improved without a loss in the random-error correcting capability and performance comparison in the digital video camera records (DVCR) system shows the superiority of the proposed CCP code over conventional product codes.

The Chinese Communist Party's 'with-Chinese-characteristics' discourse proclaims its superiority in reflecting people's genuine needs without poisonous partisan politics, as in Western democracies. The Party's Consultative Democracy is key to this superiority. To evaluate Consultative Democracy in Contemporary China from a perspective of popular sovereignty, which is the essential purpose of every kinds of democracy, this research looks into Consultative Democracy from two dimensions: theoretical dimension and institutional dimension. Theoretically, CCP's Consultative Democracy seeks its theoretical sources from their traditional thought as well as from Marxism, and especially emphasizes CCP's leadership to fulfill the consultation results. And through the analysis of various field investigations, we find that there are some prominent problems in grass-roots society's institutional mechanism for Consultative Democracy, such as insufficient connection between institutional innovation and existing legal system, inefficient consultation, insufficient representation of consultative subjects and weak motive force for sustainable development. By legitimizing certain groups or individuals as representatives in their consultative process, CCP can be de-legitimize by containing, dividing or denouncing others so that critics can be co-opted, neutralized or isolated. The CCP's consultative and representational processes are different from taking policy inputs as dialogue or negotiation as in democracies, it is a dynamic, largely one-way process of enforcement and direction with a clear political agenda: maintaining Party hegemony.
