  • Wheat straw was treated with 4 per cent urea at a moisture level of 50 per cent alongwith different levels of boric acid viz. 1, 2, 3 and 4 per cent, under laboratory conditions to know the impact of boric acid on ammonia-N fixation in the straw. Murrah buffaloes were used for determining the disappearance of dry matter, CP and fibre constituents by nylon bag technique. Ammoniation increased CP content of wheat straw, which increased further due to addition of boric acid. Low level of boric acid (1%) had no adverse effect on fibre constituents disappearance but at higher levels there was a depressioon in the disappearance of fibre coonstituents. It can be concluded that low level of boric acid was sufficient to trap the excess ammonia released during urea ammoniation of wheat straw without affecting other constituents and their disappearance in the rumen of buffaloes.

  • The seakeeping performance can be defined as the ability of a ship to go to sea, and successfully and safely execute its missions even in adverse environmental conditions. From the viewpoint of safe operation, it is primarily important to estimate the seakeeping performance of a ship in a seaway. A method of evaluating navigational safety is presented by means of the integrated seakeeping performance index(ISPI) by measuring only vertical acceleration. Judgement of dangerousness is carried out for two types of naval vessels in applying the involuntary speed losses. The used models for computer simulation are Lpp 175m light aircraft carrier and Lpp 93m frigate. In developing the practical evaluation system of navigational safety, it is expected to be useful to solve the difficulties in measuring factors by sensors. The results are also useful for developing the optimum type of naval vessels by applying at the initial design phase.

  • Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare. Moreover, drug-related pulmonary toxicity is particularly rare. An 11-year-old male patient was hospitalized for recurring upper abdominal pain after meals with vomiting, hematochezia and exertional dyspnea developing at 2 weeks of mesalizine therapy for UC. The serum level of lipase was elevated. Chest X-ray and thorax computed tomography showed interstitial pneumonitis. Mesalizine was discontinued and steroid therapy was initiated. Five days after admission, symptoms were resolved and mesalizine was resumed after a drop in amylase and lipase level. Symptoms returned the following day, however, accompanied by increased the serum levels of amylase and lipase. Mesalizine was discontinued again and recurring symptoms rapidly improved.

  • Many farmers apply cattle slurry on grassland, often in excess of crop N requirements, resulting in groundwater contamination. Our research objective was the development of grassland management systems that reduce undesirable sideeffects on other compartment of the ecosystem. Field experiment was conducted during 1991~1993 on sandy loam soil at AllgZiu south western Germany. Different sets of conditions were tested such as : zero fertilization, reduced sluny application$(l20kg N ha^{-1}yr^{-1})$, intensive sluny application(conventional sluny application, $240kg N ha^{-1}yr^{-1}$). The plots of the reduced slurry application had no significant effect on dry matter yields, digestible dry matter and net energy of herbage. Dry matter yield of zero fertilization was significantly lower than that of usual slurry application, however the content of Ca and Mg in herbage tended to increase. We conclude that reduced sluny application can be applied on grassland without adverse effects on dry matter production and quality of herbage.

  • Benzodiazepines are widely used for a variety of conditions in psychiatric field. In this article, the author reviewed the indications, the effects on anxiety and sleep disorders, the side effects, the drug-drug interactions, and the tapering strategies. Benzodiazepines were relatively safe and useful for the treatment of anxiety and sleep disorders. However, used clinically, benzodiazepines can induce many adverse effects (e. g. over-sedation, cognitive impairments, paradoxical effects, dependence and withdrawal symptoms, and so on). Currently available informations about their effects on the developing fetus is controversial. For this reason, pregnant women and nursing mother should be cautioned against the use of benzodiazepines. Drug-drug interactions have to be considered in combination treatments. For the tapering issues, gradual tapering was important to prevent the withdrawal symptoms. Especially, the tapering schedules have to be individualized for the each long-term benzodiapzepine users.

  • The base of leisure air activities are consistently expanding and its demand is expected to increase attributed to GDP growth and people's interest in its activity. Utilizing Visual Flight Rule, light sport aircrafts and ultra-light aircrafts are not under the effect of air traffic control center, which resulted in passenger injury due to emergency landing for adverse weather conditions and technical issues after pulling into mountain area, ocean and even urban area. Such events encouraged safety consciousness toward leisure aircraft activities and developing a measure to prevent a recurrence of the accident. This research focuses on suggesting compositive system for preventive safety management system by providing user based Flight information service and operating effective system, necessary for leisure aircraft activities.

  • There are many factors that affect speech intelligibility and speech acceptability. Structural anomalies and neuromotor pathologies are known for the reasons of abnormal speech sounds. And there are minor variations related to oral mechanism. Speaking with restricted mouth opening related to therapeutic procedure or habitual speech pattern might affect the quality of speech sounds. So this study compared speech intelligibility and speech acceptability of recorded 24 words in two conditions (restricted mouth opening condition and normal mouth opening condition) by 30 normal hearing adults. The results showed that speech intelligibility and speech acceptability were significantly lower in restricted mouth opening condition. And speech acceptability was significantly lower than speech intelligibility in restricted mouth opening condition. Speech acceptability in restricted mouth opening condition was significantly lower especially in open vowel. These findings indicated that the mouth opening condition could affect vowel shape and could be an adverse effect on speech intelligibility and speech acceptability.

  • The ecotoxicity assessment of nanomaterials (NMs) in the environment is actively conducted throughout the world because of the concerns about their potential risk from usage and release into the environment, as well as their unique physiochemical properties. Ecotoxicity tests for NMs have been conducted using various species and methods; however, in spite of these efforts, the characteristics and toxicity of NMs have not been defined. The fish embryo toxicity test (FET) has been conducted extensively to evaluate the toxicity of NMs as an alternative to a whole-body test in fish. In this study, we collected and analyzed the trends of nanotoxicity on the early development of freshwater fish. The model nanomaterials are carbon NMs ($C_{60},\;C_{70},\;C_{60}$(OH)n and carbon nanotube). Their adverse effects were extensively investigated based on the properties of NMs, test species, and diverse exposure conditions.

  • Ginseng has long been used as a functional food or therapeutic supplement and it is empirically known to be safe and nontoxic. During recent decades, a number of in vitro and in vivo experiments, as well as human studies have been conducted to prove the safety of various types of ginseng samples and their components. Clinical trials, case reports, and in vitro and in vivo research articles addressing the safety, toxicity, and other adverse events of ginseng application were selected and reviewed. Patient risks associated with ginseng abuse and misuse such as affective disorder, allergy, cardiovascular and renal toxicity, genital organ bleeding, gynecomastia, hepatotoxicity, hypertension, reproductive toxicity, and anticoagulant-ginseng interaction were reviewed and summarized. There are some cases of patient risk associated with ginseng abuse and misuse depending on patients' conditions although further investigation in more cases is required to clarify these issues.
