The rapid development of biotechnology has increased the importance of microorganisms or their genetic information. Thus, the Nagoya Protocol on access to genetic resources and the fair and equitable sharing of benefits arising from their utilization was established, and countries are working to secure industrially and academically useful bioresources to deal with the agreement. In the case of Korea, because 67% of bioresources are imported from abroad, we are required to secure domestic bioresources as well. The number of isolated foodborne illness-causing microorganisms is predicted to invrease based on the incresing number of outbreaks of foodborne illness each year. Consequently, appropriate long-term preservation methods are necessary to secure the isolated microorganisms for the purpose of research and resourcification. Therefore, the long-term preservation methods for bacteria, fungi, viruses, and protozoa were investigated in this study, from domestic and international bioresource banks, and the functions of the cryoprotectants were reviewed and discussed. This review should be informative in the preservation of microorganisms and contribute to the development of biotechnology.

This mini-review focused on the current advances in the development and the application of the antibacterial agents produced from probiotics strains against foodborne pathogens. Inhibitory activity of the pathogen growth could be achieved by co-culture with probiotics and/or the treatment of metabolites extracted from probiotics culture, whereas strain-dependent efficacy was mainly reported according to the bacterial species of the target pathogens. To overcome the limited antibacterial spectrum and the efficacy of the metabolites from probiotics, the recent research highlight the discovery of novel bioactive substances with broad range of the inhibitory activity of foodborne pathogens and mode-of-action which has not been reported as the major research goal. Moreover, understanding the distribution of functional and regulation genes coding the production of the antibacterial metabolites based on the bacterial genome analysis can provide the clues for the mechanisms of the pathogen control by using probiotics. Major strategies on the application of the genomics in this research area can be represented as follows: 1) functional annotation specialized for antimicrobial proteins, 2) assessment of the antibacterial effects followed by the general/functional annotation, 3) genome and metabolites analysis for the purification of antimicrobial proteins, 4) comparative genomics and the characterization of antimicrobial potential. Especially the relationship between phenotype-genotype based on genomic bioinformation with the results of the practical efficacy tests of bacterial metabolites as an active substance of disinfectants and/or preservatives can be expected to act as supportive research for broadening our knowledge regarding the key metabolic pathways associated with the production of antibacterials from probiotics.

Purpose: This study was conducted to identify the experiences of families caring for patients with home mechanical ventilation. The question was, “What is the caregiving experience of a family who has a member with home mechanical ventilation?”. Methods: This study was a qualitative study to explore and describe the implications of experiences of families caring through a phenomenological approach. One-on-one in-depth interviews were conducted with family caregivers who worked as full-time for caring for patients with home mechanical ventilation, and the results were analyzed using Colaizzi’s (1978) phenomenological method. Participants’ relationships to patients were 1 spouse, 1 father, and 6 mother. The ages of the participants were between 33 and 59, with an average of 45.1. Results: In this study, family members’ caregiving experience was emerged. Analysis revealed the following themes: Felt burdened but had to accept it; Seized by fear; The weight I must bear alone; Everything is difficult and unfamiliar; Still, my home; and Sorry for the other family members. It was found that caregivers had decided to discharge their loved ones from the hospital out of a sense of duty. Conclusion: The families took care of the patients with responsibility and love. The study results should help with the understanding of a family with a member with home mechanical ventilation and should be used to develop nursing, mediating, and consulting programs for these caregivers

Background: Push-up are effective exercises for shoulder stability. Previous studies have documented the effects of support plane and hand position and width on muscle activities during a push-up. Objects: This study aimed to investigate the changes in muscle activities in the upper extremity when performing the standard and the knee-flexed push-up with different hand shapes. Methods: A total of twenty-six healthy males participated in this study. Three different hand shapes (finger abduction, finger adduction, and fists) and two types of push-up posture (standard and knee-flexed push-up) were set as the independent variables. Electrograms were used to measure the muscle activity of the upper trapezius (UT), triceps brachii (TB), pectoralis major (PM), and serratus anterior (SA). Each participant performed the randomly assigned push-up to the sound of the metronome. The mixed-effect linear regression model was used to detect the changes in muscle activities after changing the hand shape and push-up posture. Statistical significance was set at α = 0.05. Results: The UT muscle activity was statistically significantly higher when performing push-up with fists than finger abduction (p = 0.035) or finger adduction (p = 0.044). During the standard push-up, the muscle activity in all muscles was that the push-up with fists showed the highest muscle activity compared to the finger abduction (p < 0.01) and finger adduction (p < 0.01). Regardless of the shape of the hand, UT had the lowest muscle activity compared to other muscles (p < 0.001). In contrast, the SA muscle had the highest muscle activity among four muscles during the standard push-up. Conclusion: Based on the results of this study, we suggest hand shape is related to the difficulty level of push-up either in the standard or the knee-flexed push-up, especially in the push-up with fists. In addition, knee push-up can be recommended as shoulder musclestrengthening exercises for individuals with low shoulder muscle strength.

본 연구에서는 용매로 침액되었을 시 전반적으로 더 균일한 상전이법 기반 평막 제조 시 주로 사용되는 부직포 지지체의 영향을 분석하였다. 도프용액의 점도가 낮을 경우 용액이 부직포층으로 쉽게 침투하여 불균일한 막이 형성되는 것 을 확인하였으며, 이를 방지하기 위해 부직포층을 유기용매로 침액하는 기법을 도입하였다. 부직포층이 유기 분리막이 생성 되는 것을 확인하였으며, 수투과 및 용매투과율도 향상하는 것을 알 수 있었다. 부직포 침액의 영향은 낮은 점도에서 확연하 게 나타났으며, 고분자용액의 점도가 높은 경우 침액 여부에 관계없이 동일한 성능을 얻을 수 있었다.

The purpose of this study was to examine the microbiological and physicochemical changes on packaged tofu stored at temperatures of 5, 13, 23, and 30oC, and measure the consumable period from the expiry date to ultimately evaluate the microbiological safety on the extension of the consumable period. From the investigation, the pH value of tofu at each storage temperature (5, 13, and 23oC) showed a slight decrease over the storage period, although there was no significant change. The hardness of packaged tofu decreased more rapidly as temperature and storage time increased and the tofu started to show signs of decomposition at the same time. Analysis on the microbial change of tofu at different storage temperature revealed that the number of general bacteria also increased as the temperature increased. It was further found that packaged tofu takes 25 days at 5oC, 7 days at 13oC, and 1 day at 23oC from the expiry date until the general bacteria count is at least at the early decomposition level which is 10oC log CFU/g. However, no coliform bacteria was detected from tofu after storing at 5, 13 and 23oC. When packaged tofu was stored at 5oC, the L value changed significantly after 26 days, whereas the a and b values showed no significant change during the storage period (P>0.05). When storing tofu at 13oC and 23oC the L value decreased after 8 and 3 days, respectively. However, both a and b values increased (P<0.05).
