This study investigated removal characteristic of soluble Cs in water by RPT (Radioactivity pollutant treatment) with coagulation and sedimentation. The RPT conducted with various chemical and natural coagulants to remove the soluble Cs which consisted pre-adsorption, Sedimentation and post-adsorption. Natural absorbent included Illite and zeolite. Especially, Illite divided LPI (Large Particle Illite) and SPI (Small Particle Illite) by grain size. Also, Chemical coagulants included high basicity PAC (poly aluminum chloride). The adsorbent had a plate structure mainly composed of quartz, albite and muscovite. The surface area were $4.201m^2/g$ and $4.227m^2/g$ and the particle sizes were $197.4-840.9{\mu}m$ and $3.28-53.57{\mu}m$, respectively. The adsorption efficiency of the natural Illite was 82.8% for LPI and 85.6% for SPI. The removal efficiency of turbidity, which was an indirect indicator of adsorbent recovery, was 96.4% and 98.3%, respectively.

Protein-energy malnutrition, PEM, and increased hs-CRP level are considered to be associated with increased risk of cardiovascular disease (CVD) in hemodialysis (HD) patients. This is commonly referred to as the vicious circle of malnutrition-inflammation-atherosclerosis cardiovascular disease (MIA syndrome) in chronic kidney disease (CKD). Low protein intake can decrease the serum level of albumin and increase inflammational markers; further, both low serum albumin and high hs-CRP are independent risk factors for all-cause mortality in HD patients. The aim of this study is comparing the serum levels of albumin and hs-CRP in HD patients according to the protein intake levels. The total number of subjects was 60 hemodialysis patients; they were grouped by dietary protein intake: low protein intake group (LPI, protein intake < 1.0 g/kg IBW, 11 men and 19 women) and adequate protein intake group (API, protein intake ${\geq}$ 1.0g/kg IBW, 12 men and 18 women). Blood biochemical parameters, nutrient intake, and dietary behaviors were compared between the LPI and API groups. The LPI group showed a significantly lower serum level of albumin and higher serum level of hs-CRP than the API group (p < 0.05). The LPI group showed a significantly lower intake of most nutrients than the API group (p < 0.05). Index of Nutritional Quality of most nutrients of the LPI and API groups were lower than 1.0. Dietary protein intake was positively correlated with the serum level of albumin (r = 0.306, p < 0.05) and negatively correlated with the serum level of hs-CRP (r = -0.435, p < 0.01). The serum level of hs-CRP was negatively correlated with that of albumin (r = -0.393, p < 0.01). According to these result, serum albumin and hs-CRP in HD patients were influenced by the protein intake levels. To prevent MIA syndrome, it is necessary to improve nutritional status, especially in protein and energy.

본 논문에서는 엔진의 엔진성능, 안전성 및 내구성에 직접적인 영향을 미칠 수 있는 LP 연료필터의 유동 특성을 분석하고자 하였다. LP 연료필터를 3차원 모델링하였으며, 유동해석을 위하여 계산격자를 구성하고 유동해석을 수행하였다. 유동장을 분석하여 입구부를 거쳐 연료필터를 지나 출구부까지 유동이 원활한 것을 확인하였고, LP 연료의 유동장은 필터내에서 양호한 것으로 판단된다. 또한, 연료필터 내부의 압력강하량을 분석하였으며, 질량유량이 증가함에 따라 압력강하량이 증가하였다.

FM screening has been praised for its apparent resolution advantage over conventional AM screening. FM screening is also known for its criticalness of film output and difficulties in the proofing stage because of the microdot formation. However, FM screening is not a well understood process from press performance point of view. This study was carried out for the purposed of introduction the availability of hifi-offset printing to domestic printing industries and evaluating the print qualities between 300pli AM screen and FM screen with the equivalent sized microdots to 4-5% dot area of the 300lpi AM screen, together with comparing with the 175lpi AM screen representing a conventional printing. Solid density, dot gain, color gamut and some other quality properties were measured and discussed.

This study was carried out to developed that appraisement model of Potential Productivity Index (PPI). PPI model was used Farmland Productivity Index(FPI) and Labor Productivity Index(LPI) by GIS, and PPI model applied to farm land consolidation region which has been completed recently. FPI was determined by overlapping Poly Grid of the soil properties at the analyzed project region. LPI was estimated by addition productive wages ratio of total direct productive cost. Addition productive wages was determined by GIS Network analysis of working distance between farm house to paddy and each paddy. PPI variation of each the analyzed paddy of Masu and Weoncheon region was $0.967{\sim}0.712,\;0.986{\sim}0.780$ respectively, and could be showed relative largely PPI value. PPI will provide basic element for large scaling and gathering of farm land and a substitute lot of farm land consolidation, and will be maximize productivity of paddy.

This paper presents the mapping of liquefaction for the Incheon Song-do reclamation area using both the liquefaction potential index(LPI) and the equivalent liquefaction factor of safety(FE). As a result, the mapping of liquefaction based on LPI and FE shows similar distribution pattern. Therefore, the mapping of liquefaction presented in this study will be a convenient index for use when the mapping of liquefaction for the Incheon Song-do reclamation area is drawn up. It will make selection of area that needs specific estimation and areas with adaptation of liquefaction counteraction construction methods for the future reclaimed land with the economical soil investigation.

In this paper, we have introduced a Code Division Multiplexing transmission method which is similar to OFDM and analyze ECCM performances. We have verified CDM transmission method has a good LPI performance and a feasible ECCM performance. This capability could be useful for reduction of RF interference which occurs when many equipments operate densely in small area. The equipment that uses CDM transmission method supports variable transmission rate and order-wire effectively and conveniently to user. This CDM method has similar ECCM performance comparing to serial DS method. CDM method has good multi-path signal processing capability and could be useful for mobile communication environment.

The purpose of this study is to carry out the task of engine hesitation which occurred intermittently in driving due to the defective CKPS of LPI vehicles. As the result of the wrong data from the equipment of D-logger, the signal error of CKPS caused the engine hesitation. We performed a study in the followings to analyze and investigate the cause effectively. First, we have investigated the control wiring harness and connector pin contact defect inspection. Second, we have inspected the defection of CKPS separately. From this study, it was found that the engine hesitation were caused by the bad durability and we have showed how to diagnosis the fault of the engine hesitation intermittently while driving. Therefore, it is determined that we have to improve the durability of the CKPS through a strict quality control and to increase the reliability.

The association of replication origins/termini with nuclear matrix during S phase was investigated by DNase digestion of halo structures in synchronized mouse LPI-1 cells. The binding of parental DNA to nuclear matrix was constant throughout S phase. When nuclear matrix was isolated from the cells pulse-labeled with 3H-thvmidine at various stases of S phase, total 3H-labels associated with nuclear matrix were specifically higher at So, Sa and Ss stages than other stases of S phase, suggesting that the newly synthesized DNAs at those stages are not excluded out of nuclear matrix. Similar patterns were obsenred from the pulse-chase experiments, in which cells were pulse-labeled at each stage of S phase and further incubated for 1 hr. These results suggest that the replication origins and termini are fixed at the nuclear matrix, and that the nuclear matrix binding fractions of DNA at 3C-pause may contain a large population of replication origins and termination sites.
