Purpose: The purpose of the study was to contribute to the prevention of musculoskeletal disorders (MSDs) in 119 emergency medical technicians (EMTs) by evaluating ergonomic risk factors of patient lifting work-postures. Methods: Four procedures were evaluated: using long back-board (LBB) on the sitting and standing main stretcher, using variable stretcher on the sitting and standing main stretcher. Wok-postures were assessed during training. Results: In using LBB on the sitting main stretcher, the OWAS-score was Mode:3 (Mean:2.30, Maximum:3), the REBA-score was Mode:9 (Mean:7.61, Maximum:11), requiring improvement soon. In using LBB on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.33, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:6 (Mean:5.44, Maximum:11), requiring improvement. In using variable stretcher on the sitting main stretcher, the OWAS-score was Mode:1 (Mean:1.85, Maximum:3), not requiring corrective action, the REBA-score was Mode:6 (Mean:6.78, Maximum:11), requiring improvement. In using variable stretcher on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.84, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:11 (Mean:9.38, Maximum:11), requiring immediate improvement. Conclusion: All four-procedures showed improvement in work-posture. Thereby, required attention and management in training, occupational health professionals should participate in change of lifting-method, and programs aimed at preventing MSDs should be developed and implemented in fire-academy and fire-station.

Background: Oversight on the bioethical compliance of national R&D projects or research personnel is currently conducted exclusively by IRB (Institutional Review Board) within the relevant research institute. Considering current state of affairs in Korea, there is an imperative to establish a national oversight system for bioethical compliance, conduct comprehensive oversight on bioethical compliance of national R&D projects, and enhance subject protection system. Methods: We examined opinions from researchers and IRB personnels regarding ethical oversight system on R&D projects. Additionally, we looked at IRB assessment by KAIRB (Korea Association of Institutional Review Board) in order to identify status and problems with current IRB system in Korea. Assessment was also done for four other countries (US, UK, Germany, Singapore) through in-person visits as well as surveys in writing for a total of 6 months (2012.12.1~2013.5.31). The research comprised of two aspects: system management and R&D project audit. Based on this, we examined current status and problems of the existing system in Korea and made recommendations for improvement. Results: Regulatory objectives and backgrounds of biomedical researches are different from each country due to different characteristics of bioethical oversight system. This shows that each country sets up its own regulations and procedures to fit each situation. Bioethical compliance oversight system greatly varied between the countries. From this study, it can be seen that improvement of existing procedures and oversight system or establishment of new ones are essential in Korea. Conclusion: In terms of system management, a dedicated government organization need to be established for bioethical compliance, subject protection, IRB inspection, training, evaluation, and certification of systems, and also support for IRB e-system. Regarding R&D project oversight, it is essential to confirm IRB review results before start of a research, to conduct a review on ethical aspects of research plans, and to carry out continued oversight on bioethical compliance through interim reports.

A new high yielding mulberry genotype, Victory-1 (V-1) was recommended to the field for irrigated areas by Central Sericultural Research and Training Institute (CSRTI), Mysore during 1996-1997. As K-2 and S-36 mulberry genotypes are already in the field, a study on the comparative performance of V-1, 5-36 and K-2 varieties, in terms of leaf yield, yield attributes, leaf moisture and moisture retaining capacity and their impact on silkworm rearing was carried out under Telangana conditions of Andhra Pradesh during 1999-2001. Among the three genotypes the leaf yield was found to be significantly (P < 0.01) higher in V-1 (64,130 kg/ha/yr) followed by S-36 (44,064 kg/ha/yr) and K-2 (23,990 kg/ha/yr). The maximum leaf moisture was also observed in V-1 (71.84%) compared to S-36 (66.86%) and K-2 (64%). The moisture retaining ability was more in V-1 (70.17%) followed by S-36 (66.20%) and K-2 (60.08%). The yield attributes were found to be significantly (P < 0.01) enhanced in V-1 over S-36 and K-2. Silkworm rearing results (bioassay) indicated a significant (P < 0.01) reduction in larval duration and improvement in larval weight, effective rate of rearing by number and weight, single cocoon and shell weights and shell ratio in the silkworm lots fed on V-1 variety followed by S-36 and K-2. Hence, in this study, V-1 was found to be superior among the three varieties studied.

Anti-fungal potential of 5 plant extracts viz., Eucalyptus citriodora, Allium sativum, Cassia sophera, Chromolaena odorata and Datura metel on the growth of mulberry brown leaf spot pathogen Myrothecium roridum were examined. Except fur the aqueous extract of Allium bulb, ethanolic leaf extract of all other plants more efficiently reduced the colony growth of the fungus on potato-dextrose-agar, Of which, Allium and Eucalyptus extracts were more effective. Initiation of radial growth of M. roridum on solid media was deferred maximum 6 days by ethanolic Eucalyptus extract and 4 days by aqueous Allium extract at $0.4 mg.ml^{-1}$. In the liquid media amended with Eucalyptus extract ($0.4 mg.ml^{-1}$) complete inhibition of sporulation was noticed upto 8 days, and initial inhibition of mycelial bio-mass generation was considerably diminished with time and reduction was 1.3 fold 14 days after application. While, complete inhibition of mycelial growth for 6-14 days was recorded with $\geq$0.1 mg.ml$^{-1}$ commercial eucalyptus oil. However, rejuvenation of growth appeared when fungus was re-inoculated in fresh media. Post-inoculate application of different doses Of Eucalyptus and Allium extracts significantly (p < 0.05) reduced the disease severity in pot-ted mulberry. However, persistence of the effect up to 28 days was apparent at $\geq$ 1.0 mg.ml$^{-1}$ and effectively was on par with carbendazim (1 mg.ml$^{-1}$ ). Almost equal control ability of 1.0 mg.ml$^{-1}$ Eucalyptus extracts can be achieved by ca. 10 times lowered dose of commercial eucalyptus oil. It seems, the toxic principle of E. citrodora to M. roridum is fungistatic in nature and may have essential oil based origin.

This study represents a fundamental research for a passenger-ship escape guidance system that is a ship-borne agent, and it is for the support of escape decision-making by providing accurate maritime safety information in real time. We conducted a passenger escaping experiment on a training ship, SAEYUDAL, using the situation-aware escape guidance system, which has been developed for on-board application based on products for buildings. It is shown that the system contributes to the shortening of the escape duration and the dispersion of the escaping persons by generating and guiding the safe escape routes which dangerous areas are considered. From the experiment on ship's heeling condition, it is revealed that the heeling angle is linearly related to the escape duration. Therefore, this study shows that the shortening of the escape duration enables a safe and rapid mustering that is the most important process under emergency and appropriate incident responses to minimize loss of lives.
