  • The International Maritime Organization (IMO) has adopted the ballast water management convention at a diplomatic conference in early 2004 that all ships should be equipped with a treatment system from 2010 gradually. In this paper, the disinfection characteristic of ultra-violet (UV) rays was studied and a ballast water treatment system (BWTS) which can treat $50m^3$/h sea water was manufactured. The system consists of a disinfection chamber with six 3.5 kW UV lamps which are operated by magnetic ballasts, a programmable logic controller (PLC) and set of pipe lines. The biological disinfection efficacy of the prototype BWTS was evaluated following the IMO rules using zooplankton such as Artemia and Rotifer species for the size over $50{\mu}m$, and phytoplankton such as Tetraselmis and Thalassiosira species for the size between 10 to $50{\mu}m$. From the experimental results, the disinfection efficacy was 99.99 % that meets the IMO requirement. However, more studies on an energy saving system are needed because the consumption power of the prototype system is as high as over 21 kWh for $50m^3$/h.

  • There are several methods of pest control for the prevention of wooden cultural properties from damages caused by insects, especially termites. Those are as follows; physical control, chemical control, biological control, and integrated pest management. In Korea, we primarily use mvestigation of monitoring, fumigation, treatment of insecticidal and antiseptic chemicals, soil termiticide treatment, and termite colony elimination system. As damages by termites were detected at Eunghyanggak and Saundang of Haeinsa temple in June, 1998, we carried out monitoring with wooden device, in order to investigate damages of wooden building by termite and paths of termite invasion. According to the result of investigation of monitoring from1999 to 2002, we found that termites were inhabiting continually at forests around Haeinsa and that wooden buildings such as Saundang, Cheonghwadang were damaged by termites. So we thought that control methods such as soil termiticide treatment and termite colony elimination system would be effective. Especially, to investigate efficacy of termite colony elimination system, we carried out efficacy test of termite colony elimination system in Jongmyo during 17 months(2000.7.~2001.11.). The result of efficacy test showed that termite colony elimination system eliminated termite colonies gradually(over 12 months from installation of colony elimination system to elimination of termite colony).

  • Background: There are few pharmacologic options to reduce erythema and flushing in patients with recalcitrant erythematotelangiectatic rosacea (ETR). We previously reported two cases of refractory flushing and erythema of rosacea that were successfully treated with intradermal botulinum toxin injection, and additional research is needed to prove the efficacy and safety of this treatment. Objective: To report the efficacy and safety of botulinum toxin injection as an aid in persistent erythema of rosacea patients. Methods: A total of 20 Korean patients with recalcitrant ETR were enrolled to receive treatment by injection of botulinum toxin. Patients received one treatment of intradermal botulinum toxin injection and were assessed 1, 2, 4, and 8 weeks after treatment. The severity of erythema and telangiectasia was investigated by a non-treating physician, and the Erythema Index (EI) was assessed by mexameter at each visit. Patient satisfaction and any adverse events were also assessed at each visit. Results: 17 patients completed all follow-up visits and were included in the analysis. Intradermal injection of botulinum toxin significantly reduced erythema severity and EI in ETR patients. Patients reported a satisfaction score of $2.94{\pm}0.56$ at 8 weeks after treatment. Except for three patients who discontinued the study early due to inconvenience of facial muscle paralysis, 17 patients participating in the final analysis did not report side effects except injection pain at the time of the procedure. Conclusion: Intradermal injection of botulinum toxin can be used as an effective and relatively safe adjuvant agent for recalcitrant and persistent erythema of ETR patients.

  • We tested the pre-treatment of alumina, leucine, alumina mixed with leucine at ratios of 9:1 (Al-Leu (9:1)) and 5:1 (Al-Leu (5:1)), and alumina mixed with sodium lactate at a ratio of 5:1 (Al-Lac (5:1)) on aged fingerprints (1, 7, 14, and 30 days after natural fingerprinting) before cyanoacrylate (CA) fuming to improve the development efficacy. As a result of the experiment, fingerprints with pre-treatment of alumina, leucine, Al-Leu (9:1), Al-Leu (5:1), and Al-Lac (5:1) showed better development efficacy (area and minutiae) than fingerprints without pre-treatment. Therefore, this modified CA fuming method improved the development efficacy with five pretreatments.

  • Introduction: Qūbā (Tinea Corporis) is a very common disease widely prevalent worldwide. 20 - 25 % individuals suffer for this stubborn disease. Unani System of Medicine offers its treatment. There are many pharmacopoeial formulations indicated for various types of dermatophytic infections. In this study clinical efficacy and safety of the topical Unani formulation Marham Kharish Jadeed (a compound drug in the dosage form of an ointment) was assessed and compared with a standard conventional medicine. Materials and methods: A clinical study was conducted on 60 participants of qūbā randomized into test and control groups (n=30 in each group). The participants were clinically diagnosed and confirmed by microscopy of skin scrapings. The efficacy of the Unani formulation was assessed in terms of TSS score and elimination of fungal elements from the skin lesions. The data collected were analyzed statistically. Results and discussion: The study showed that the Unani formulation had comparatively better efficacy clinically than conventional medicine Terbinafine hydrochloride 1% cream in terms of reduction of itching, erythema, scaling, peripheral raised margins of the lesion comparing to baseline. In this study, 27 participants in test group and 18 participants in control group were completely cured (≥75% reduction in TSS Score with Mycological Cure) after 4 weeks of treatment. The efficacy of the Unani formulation was found significant statistically. The individual drugs of the formulations having analgesic (Musakkin), blood purifier (Muṣaffi-i-Dam), demulcent (Mulaṭṭif), antifungal (Qātil-i-fafūndῑ), detergent (Jālῑ), refrigerant (Mubarrid) and antiseptic (Dāfi'-i-'Ufūnat) properties might be responsible for the efficacy of Unani formulation. Conclusion: The findings of the study suggested that the Unani formulation was found effective and safe in the management of qūbā. No local and systemic adverse effect was reported during the study.
