한국어 명사 어절의 시간 경과에 따른 처리 양상을 확인해 보기 위하여 점화어절판단과제(primed eojeol decision task)를 이용한 실험을 실시하였다. 점화어 제시 방식은 차폐점화, SOA 100ms, SOA 300ms 조건으로 하였으며, 점화어-표적어의 관계는 어절일치, 어간일치, 통제조건으로 조작하였다. 그 결과 어절일치조건과 어간일치조건에서 촉진효과가 있었으며, SOA가 증가함에 따라 어절일치조건과 어간일치조건에서의 촉진효과도 함께 증가하는 양상을 확인하였다. 점화어의 제시 방식과 점화어-표적어의 관계간의 상호작용도 유의미하였다. 이러한 결과를 바탕으로 심성어휘집에서의 어절 표상의 실재성과 어절 속성과 어간 속성이 어절 처리 과정에 관여하는 방식에 관하여 논의하였다.

사람의 항 HLA 단일군 항체 생산의 선결 조건인 가장 효과적인 시험관내 면역 조건을 확립하기 위해, 사람의 혈중 임파구를 함원으로 하여 마우스의 대식세포, 흉선세포. 이들의 조건배지, 그리고 임파구 촉진인자 등을 포함한 14가지의 다양한 배양 조건에서 세포를 배양하였으며, 마우스의 비장세포와 사람의 혈중 임파구에서 각각 항체 생산을 유도하였다. 항체의 생성 여부는 면역효소법(I섬SA)으로 조사하였다. 마우스의 비장세포는 모든 조건에서 다량의 항체가 검출되었으며, 사람의 혈중 임파구 분화에는 마우스의 조건배지보다 PWM. LPS와 같은 임파구 촉진인자가 효과적임을 알 수 있었으며. 특히 allogenic MLC(Mixed Lymphocyte Culture)에 의해 임파구 분화유도에 유용한 물질이 생성됨을 알 수 있었다.

The pulished works on Accelerated Curing Effect were generally performed around from 1960 to 1970th century for 18 to 24 hours - total curing periods. It is not possible to define the effect of temperature rise because those results were obtaine mainly by using the manually operated steam-curing tank. Thus, it may not be available to apply those data immediately on the domestic PC wall production line. The testing specimens were made from the standard mix proportion according to those of domestic PC factories to establish a basic data for the Accelerated Curing Effect. The experimental tests were conducted according to the conditions of each sub-curing periods. By comparing the results of compression tests on de-molded and 28-day water-curing specimens, we find that the most effective curing condition to obtain more than the required design strength after 28 day of water curing may be as follows: the presteaming period does not affect seriously and less than$30^{circ}C/hr$- the rate of temperature rise andless than $82^{circ}C$ - maximum temperature are necessary. It seems that post-curing procedure is very important factor to increase the effect of accelerated curing.

This paper describes the application of bioluminescence stimulating agents on a genetically engineered microorganism, Pseudomonas putida mt-2 KG1206, to monitor toluene analogs using in groundwater samples from petroleum hydrocarbon contaminated sites. The maximum bioluminescent response with pure chemicals followed in the order: m-methyl benzyl alchohol > m-toluate > toluene > m-xylene > benzoate > p-xylene > o-xylene. Generally, the bioluminescence production of strain mixed with groundwater samples was dependent on the contaminated total inducer concentrations. However, few samples showed opposite results, where these phenomena may be caused by the complexicity of environmental samples. Two chemicals, SL(sodium lactate) and KNO$_3$, were tested to determine a better bioluminescence stimulant. Both chemicals stimulate the bioluminescence activity of strain KG1206, however, a slightly high bioluminescence was observed with nitrogen chemical. This selected stimulant was then tested on samples collected from contaminated groundwater samples. The bioluminescence activity of all samples mixed with the strain was stimulated with KNO$_3$ amendment. This suggests that the low bioluminescence activity exhibited by the environmental groundwater samples can be stimulated by amending the culture with a proper agent, such as nitrogen compound. These findings would be useful, especially, when strain was used to monitor the groundwater samples contaminated with low inducer contaminants. Overall, the results of this study found the ability of bioluminescence producing bacteria to biosensor a specific group of environmental contaminants, and suggest the potential for more efficient preliminary application of this engineered strain in a field-ready bioassay.

This study was to identify the factors affecting nurses' use intention of digital healthcare and the moderating effect of clinical career based on the UTAUT model. The items were composed by performance expectancy 3 items, facilitation condition 3tiems, and perceived risk 3 items. CFA was performed to verify the construct validity. As a results, average variance extracted (AVE) was .5 or higher, and construct reliability (CR) was .7 or higher. Model fit was confirmed as CMIN/df=1.797, GFI=.955, CFI=.979, TLI=.968, IFI=.979, and RMSEA=.063. The internal reliability was .93 for performance expectancy, .84 for facilitating conditions, and .64 for perceived risk. Performance expectancy, facilitating condition, and perceived risk had a significant effect on use intention, and clinical career showed a moderating effect(t=-2.159, p=.032). Therefore, in order to enhance the use intention of digital health care, performance expectancy, and facilitating conditions should be raised and perceived risk should be reduced.

본 연구는 $\beta$-CD을 이용한 체다. 치즈의 숙성의 촉진을 위한 최적조건을 확립하기 위하여 가염의 양, 가온온도, 가온시간을 변화요인으로 연구하였다. 가염의 농도는 증가할수록 쓴맛이 낮아지는 경향을 확인하였고 hardness는 단단해지는 경향을 확인하였다. Curd의 가온시 온도가 높을수록 hardness가 가장 긍정적인 경향을 나타냈다. 가온시간은 길어질수록 short-chain free fatty acids의 양이 가장 적게 나타났다. 따라서 가염을 3%까지 증가시키고 Curd의 가온온도를 $42^{\circ}C$까지 높이면서 가온시간을 60분 까지 증가시킨다면 $\beta$-CD을 첨가한 체다. 치즈의 부스러지는 조직과 강한 쓴맛을 약화시키는 효과를 가져오면서 숙성을 촉진시킬 수 있다고 사료된다.

본 연구에서는 글이해시의 참조관계 처리과정에서 맥락이 어떤 역할을 하며 다른 통사단서와는 어떤 관계를 갖는지를 대명사 해결을 중심으로 조사했다. 실험 1에서는 대용어 문장의 국소적 맥락에 의한 촉진효과가 관찰되었다. 그러나 맥락과 통사단서간의 상호작용으로 맥락 촉진효과는 통사적 명료조건에서보다는 애매조건에서 더 강하게 나타났다. 실험 2에서는 국소적 맥락정보가 없더라도 선행글의 전체주제적 맥락정보가 촉진제 역할을 하는 것으로 밝혀졌다. 또한 전체주의적 맥락이 주어지는 경우 글의 표면구조적 특성에 따른 위치효과가 나타나지 않았다. 즉 두 개의 실험을 통해 대명사 해결에 미치는 통사단서의 효과가 일부 지지되었으며, 특히 맥락효과는 국소적, 총체적 수준에서 모두 일관되게 입증되었다.

The purpose of the present research was to examine whether the attention mechanism employs physical or represented location of the cue and target. To achieve this, we have employed the paradigm of facilitation of response as well as inhibition of return. In the experiments, valid and invalid conditions were defined by the position consistency of the cue and the target in the aspect of either physical or represented location. We used auditory cue and visual target in Experiment 1 while visual cue and auditory target in Experiment 2. As a results, in Experiment 1, effect of facilitation of response in valid condition was found when the valid/invalid conditions were defined in the aspect of represented location. In Experiment 2, effect of facilitation of response in valid condition was found when the valid/invalid conditions were defined in the aspect of represented location. In all the other conditions, no effect was found when the conditions were defined in the aspect of physical location. No effects of inhibition of return were found in Experiment 2. These results imply the possibility that attention mechanism operates based on objects' represented location rather than on their physical location. More importantly, the present research suggests that it is necessary to separate represented location from physical location of the target and the cue in the experiment of facilitation of response and inhibition of return in the future.

A study on the elution characteristics of biostimulating agents (sulfate and nitrate) from biostimulants which are used for in-situ bioremediation for the coastal sediment contaminated with organic matter was performed. The biostimulating agents were mixed with the coastal sediment, and then massed the mixture into ball. Two kinds of ball type biostimulant were prepared by coating the ball surface with two different polymers, cellulose acetate and polysulfone. A granular type biostimulant (GTB) was also prepared by impregnating a granular activated carbon in the biostimulating agent solution. The image of scanning electron microscopy for the biostimulant coated with cellulose acetate (CAB) showed that the inner side of the coating layer consisted of irregular and bigger size of pores, and the surface layer had tight structure like beehive. For the biostimulant coated with polyfulfone (PSB), the whole coating layer had a fine structure without pore. The elution rate of the biostimulating agents for the CAB was higher than that for the PSB, and the elution rate for the GTB was considerably higher than that for the PSB in distilled water as well as in sea water. The elution rate of the biostimulating agents in turbulent water flow was about 3 times higher than that in standing water, and the elution rate of nitrate was higher than that of sulfate from the stimulating agents.
