Recently the method of basal compound fertilizer (N : P : K = 18.2 : 9.8 : 35.0) Placement has been changed from banding to broadcasting in tobacco cultivation. The effects of the compound fertilizer placement, level of fertilizer and additional urea application on the agronomic characteristics, two chemical compositions and physical Properties of burley tobacco(Nicotiana tabacum L. cv. KB 108) were investigated at Chonju Experiment Station, Korea Ginseng and Tobacco Research Institute in 1995-1996. Six treatments consisted of (1) band (method of fertilizer Placement) + In kg/10a(compound fertilizer) + 0(additional urea applied), (2) broadcast+140+0, (3) broadcast+140+25, (4) band+180+0, (5) broadcast+180+0, and (6) broadcast +180+25. The additional urea was applied at hilling. No significant differences were detected between banding and broadcasting method of compound fertilizer Placement in field 9rowth, wield, organoleptic qualify(price Per kilogram), chemical composition and Physical properties of cured leaf, The increased compound fertilizer by 30%(40k/10a) or the additional urea application by 25kg per 10a produced slightly higher yield than the recommended amount of basal compound fertilizer without additional urea application did. It also increased the total alkaloid content of cured leaf. It is recommended that no more basal fertilizer above the recommended amount and no additional urea application are needed in burley tobacco fertilization, even though the method of basal fertilizer placement being chanced from banding to broadcasting. Key words : Nicotiana tabacum, fertilizer placement, additional urea.

Delay in the air transport occurs when passengers, baggage or cargo do not arrive at their destination at the time indicated in the contract of carriage. The causes of delay in the carriage of cargo are no reservation, lack of space, failure to load the cargo on board, loading the cargo on the wrong plane, failure to off-load the cargo at the right place, or to deliver the covering documents at the right place. The Montreal Convention of 1999 Article 19 provides that "The carrier is liable for damage occasioned by delay in the carriage by air of cargo. Nevertheless, the carrier shall not be liable for damage occasioned by delay if it proves that it and its servants and agents took all measures that could reasonably be required to avoid the damage or that it was impossible for it or them to take such measures." The Montreal Convention Article 22 provides liability limits of the carrier in case of delay for cargo. In the carriage of cargo, the liability of the carrier is limited to 17 SDR per kilogram unless a special declaration as to the value of the cargo has been made. The Montreal Convention Article 19 has shortcomings: it is silent on the duration of the liability for carriage. It does not give any indication concerning the circumstances to be taken into account in cases of delay, and about the length of delay. In conclusion, it is desirable to define the period of carriage with accuracy, and to insert the word 'unreasonable' in Article 19.

The purpose of this study was to determine the influence of muscle fatigue in elbow flexors on the sense of force reproduction. Fifteen healthy subjects were recruited for this study. Maximum voluntary force (MVF) of elbow flexor muscles was measured by a digital tensiometer. Force errors were measured to test accuracy of the sense of force reproduction in elbow flexors. The subject was required to flex the elbow joint, to maintain and concentrate on about 20% of the MVF target force under visual feedback for 3 seconds. After a 5 second period rest, the subject was asked to duplicate the target force actively. Muscle fatigue was evoked with isometric contraction of the elbow flexors. Isometric contraction was continued until a 50% drop in MVF. The difference, in kilogram between the target force and the reproduced force was calculated for measuring force error. Force errors were compared between the non-fatigued condition and the fatigued condition by the paired t-test. Force errors were significantly increased in the fatigued condition compare to non-fatigued condition. This result suggests that the sense of force reproduction can be disturbed by localized muscle fatigue.

Hydrogen and electricity are expected to dominate the world energy system in the long term. The world currently consumes about 50 million metric tons of hydrogen per year, with the bulk of it being consumed by the chemical and refining industries. The demand for hydrogen is expected to increase, especially if the U.S. and other countries shift their energy usage towards a hydrogen economy, with hydrogen consumed as an energy commodity by the transportation, residential and commercial sectors. However, there is strong motivation to not use fossil fuels in the future as a feedstock for hydrogen production, because the greenhouse gas carbon dioxide is a byproduct and fossil fuel prices are expected to increase significantly. An advanced reactor technology receiving considerable international interest for both electricity and hydrogen production, is the modular helium reactor (MHR), which is a passively safe concept that has evolved from earlier high-temperature gas-cooled reactor (HTGR) designs. For hydrogen production, this concept is referred to as the H2-MHR. Two different hydrogen production technologies are being investigated for the H2-MHR; an advanced sulfur-iodine (SI) thermochemical water splitting process and high-temperature electrolysis (HTE). This paper describes pre-conceptual design descriptions and economic evaluations of full-scale, nth-of-a-kind SI-Based and HTE-Based H2-MHR plants. Hydrogen production costs for both types of plants are estimated to be approximately $2 per kilogram.

The purpose of this study was to evaluate the riboflavin status of primary school children. Fiftyone subjects were selected as obese group and fiftyfive subjects were selected as control group according to Body Mass Index(BMI) of fifth-graders at a primary school in Taegu. For each subject information on nutrient intake and daily activity pattern were obtained by questionnaire. The riboflavin status was evaluated by urinary riboflavin exvretion The daily energy expenditure per kilogram of body weight was significantly lower in obese group(=47kcal/day) than in control group(=58kcal/day) (p<0.001) However the entire energy consumption was siginificantly greater in the obese children(=2005kcal/day) than their nono-baser peers(=1837kcal/day)(p<0.001). Riboflavin intake was 0.67mg/100kcal in the control group and 0.61mg/1000kcal in the obese group. Thus intakes for both groups met the current group and control group were 86.9$\mu\textrm{g}$/day and 98.7$\mu\textrm{g}$/day. repectively. There was no significnat Assesment of clinical signs of riboflavin deficiency indicated that angular lesion was 4.7% and glossitis was 6.6% of all subjects. Thirty one percent of subjects excrete riboflavin below 78$\mu\textrm{g}$/g creatinine which is defined as deficient. Therefore this group would be considered at high risk for developing riboflavin deficiency. From this study current recommendation of 0.6mg/1000kcal of riboflavin intake may not be adequate during growth and associated stress.

This study was conducted to develop an effective heparin extraction method by using low-cost and highly effective enzymes from six pig by-products (liver, lung, heart, stomach, small intestine, and large intestine), and analyze their bioavailability. Low-cost and highly effective enzymes (alkaline-AK and papain) and a common enzyme (trypsin) were used for the heparin extraction. The angiotensin I- converting enzyme (ACE) inhibitory activity and the antimicrobial activity of extracted heparin were analyzed to verify their bioavailability. The average amount of heparin extracted per kilogram of pig by-products was 439 mg from the liver, 127 mg from the lung, 398 mg from the heart, 261 mg from the stomach, 197 mg from the small intestine, and 239 mg from the large intestine. Various enzymes were used to extract heparin, and the amount of extracted heparin was similar. Based on 1 g of pig by-product, the enzymes trypsin, papain, and alkaline-AK could extract 1,718 mg, 1,697 mg, and 1,905 mg of heparin, respectively. Heparin extracted from pig by-products showed antihypertensive activity and antimicrobial activity against Staphylococcus aureus at low populations. These results indicated that heparin can be obtained from pig by-products at a low cost.

Objective: The study evaluated the impact of pharmacist inventions with the implementation of pharmacistinvolved nutritional support service at neonate intensive care unit in a tertiary teaching hospital. Method: A retrospective and observational study was carried out. The total of 58 infants in neonate intensive care unit was enrolled between January 2011 and October 2012. The pharmacist-involved total parenteral nutritional program was initiated in June of 2012. During the program, pharmacist actively participated in the multidisciplinary round with performing the interventions from reviewing the amount of combined total parenteral nutrition and enteral fluid intakes, the amount of total calories, the glucose infusion rate, and the amounts of proteins per weight in kilogram. The outcome was compared with the results from the control group which reflected the prior period of the program initiation. Result: The number of days of regaining birth weight was significantly shorter (14.5 vs. 19 days, p=0.049) and the percentage of total calorie days with >90 kcal/kg/day was increased significantly (40 vs. 13%, p=0.008) in intervention group compared to the values in control group. In addition, the total mean daily caloric intakes ($84.78{\pm}13.8$ vs. $74.86{\pm}15.36$ kcal/kg/day, p=0.018) was significantly higher in intervention group than those results in control group. There were no significant differences in safety parameters between two groups related to nutritional services of necrotizing enterocolitis, intraventricular hemorrhage, proven sepsis, and also parenteral nutrition-induced hepatotoxicity. Conclusion: Pharmacist-involved total parenteral nutrition managed program was successfully implemented. The outcome showed the improved effectiveness of total parenteral nutrition with pharmacist interventions and no differences in adverse reactions. This could prove the positive effects of pharmacist involvement on nutritional therapy for neonate population.

The effects of Houttuynia cordata powder on the growth performance of ducks were investigated. Ninety ducks were assigned into one of three dietary treatments as a completely randomized design for 6 weeks: feeds supplemented with 1% or 2% H. cordata and a control group. No significant difference was observed in feed conversion among the three groups (p > 0.05), but addition of H. cordata had a significantly positive effect (p < 0.05) on initial and final body weight, weight gain, and feed intake of the ducks. Furthermore, the effects of chemical treatment (comprising 50 g and 100 g aluminum chloride [$AlCl_3$] per kilogram litter) on the ammonia ($NH_3$) flux in duck litters were also investigated. Duck litter was treated with $AlCl_3$ at a depth of 8 cm by top-dressing; this resulted in a significant difference on $NH_3$ flux (p < 0.05) during the experimental period (but not at 2 weeks). $NH_3$ flux at 6 weeks were reduced by 25.4% and 37.5% by treatment with 1% and 2% H. cordata, respectively, compared with the control groups. In conclusion, enriching the diets of the ducks with 2% H. cordata and adding 100 g $AlCl_3$ to their litter has beneficial effects on increasing their growth performance and reducing $NH_3$ flux in their environment.
