Due to excess reactivity, fresh nuclear fuel often contains burnable poisons. This research looks at six different burnable poisons and their impacts on reactivity, material attractiveness, and waste management. An MCNP simulation of a PWR fuel pin was performed with a fuel burnup of 60 GWd/MTHM to determine when each burnable poison fuel type would decrease below a k_∞ of 1. For determining the plutonium material attractiveness in each burnable poison fuel type, the plutonium isotopic content of the used fuel was evaluated using Bathke's Figure of Merit formula. For the waste management analysis, the thermal output of each burnable poison fuel type was determined through ORIGEN decay simulations at 100 and 300 years after being discharged from the core. The performance of all six burnable poisons varied over the three criteria considered and no single burnable poison performed best in all three considerations.

The aim of this study is to find out benefits of symptom questionnaire for oriental medical treatments. We analyzed symptom questionnaire of Korean association of abdomen diagnosis and treatment. Conclusions are as below. 1. Appetite, taste and digestion have a deep connection with accumulation and muscular contracture, with which the method of reinforcement and reduction is decided. 2. Feces, urine and, sweat have a deep connection with accumulation and water, with which the method of diaphoresis, emesis and purgation is decided. 3. Thirst and chillness and fever have a deep connection with water poisons and feverish feeling, based on which the cold and heat is classified. 4. we can find out the lesions with departmentalized physical sections of the head and the face, the chest, the abdomen, the articulations, the limbs and the skin. 5. It is possible to select appropriate prescription and assess before & after treatment through the questionnaire.

The purpose of this study is to find out relationship between "Yakjing" and the textbook of herbology. Conclusions are as below. 1. The herbs of accumulation of poison(結毒) generally show cold nature and have a reducing effect, which resemble the method of treating accumulation and stagnation. 2. The herbs of muscular contracture(攣) show sweet taste and tonifying effect, fall on the spleen and the stomach and have acts of treating urgency, relieving pain and conciliating, which resemble the method of treating urgency(急)and pain from accumulation and stagnation. 3. The herbs of water poisons(水毒) are categorized as those of cold nature and dampness and we can find out that water poisons is related to cold nature. 4. The herbs of feverish feeling(煩) treat heat. 5. The herbs of cardiothoracic part have an effect of regulating Gi and treat the phlegm disease.

The generation of high purity hydrogen from reformed hydrocarbon fuels, or syngas, is essential for efficient operation of the fuel cell (PEMFC, Polymer Electrolyte Membrane Fuel Cell). Usually, major components of reformed gas are $H_2$, CO, $CO_2$ and $H_2O$. Especially a major component, CO poisons the electrode of fuel cells. The water gas shifter (WGS) that shifts CO to $CO_2$ and simultaneously produces $H_2$, was developed to a two stage catalytic conversion process involving a high temperature shifter (HTS) and a low temperature shifter (LTS). Also, experiments were carried out to reduce the carbon monoxide up to $3{\sim}4%$ in the HTS and lower than 5,000 ppm via the LTS.

Objectives The purpose of this study is to compare the common herbs for pain related disease between Yak-Jing and textbook of herbology. Methods We searched the formation of "Koho" and theory of Todo yoshimasu. We selected the common herbs that is used for pain related disease in Yak-Jing and textbook of herbology. These herbs were compared with each other. Result 1. Common Herbs for pain related disease are Ephedrae Herba (麻黃), Aconiti Lateralis Preparata Radix (附子), Euphorbiae Kansui Radix (甘遂), Euphorbiae pekinensis Radix (大戟) Daphnis Genkwa Flos (芫花), Atractylodis Rhizoma (朮), Paeonia Radix Rubra (芍藥), JujubaeFructus (大棗), Gypsum (石膏), Anemarrhenae Rhizoma (知母), Cinnamomi Ramulus (桂枝), Poria (茯苓), Rhei Rhizoma (大黃), Natrii Sulfas (芒草), Pueraiae Radix (葛根). There are some difference between textbook of herbology and Yak-Jing about Aconiti Lateralis Preparata Radix (附子), Paeonia Radix Rubra (芍藥), Atractylodis Rhizoma (蒼朮), Pueraiae Radix (葛根). 2. Preparata Radix (附子) excrete water poisons (水毒) in Yak-Jing, but it has the effect of restore yang and tonify fire (回陽補火) in textbook of herbology. 3. Paeonia Radix Rubra (芍藥) is effective for pathological condition caused by the formation of the band and spasm (結實拘攣) in Yak-Jing, but it is to cure heat pattern in textbook of herbology. 4. Atractylodis Rhizoma (蒼朮) has the effect of water-draining (利水) in Yak-Jing, but it has the effect of dispersing (發散) in textbook of herbology. 5. Pueraiae Radix (葛根) is used in dyspnea and sweating (喘而汗出) in Yak-Jing, but it is to cure engender fluid (生津), skin disease, diarrhea in textbook of herbology. Conclusion There are some difference between textbook of herbology and Yak-Jing in the herb medicine that is used in pain related disease.
