  • In this study, the changes in microbial communities of lamb meat packaged in the air (plastic tray, PT) and in a vacuum pouch (VAC) were assessed by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) during the storage at $4^{\circ}C$. For the PT lamb, the total viable count (TVC) was $10^7CFU/g$ on Day 5, and the dominated bacteria were Pseudomonas fragi, P. fluorescens, and Acinetobacter spp. For the VAC lamb, the TVC was $10^7CFU/g$ on Day 9, and the dominated bacteria were lactic acid bacteria, including Carnobacterium divergens, C. maltaromaticum, and Lactococcus piscium. One strain of Pseudomonas spp. also appeared in VAC lamb. The relative abundance of Enterobacteriaceae in VAC lamb was higher than that PT lamb, indicating a more important role of Enterobacteriaceae in spoilage for VAC lamb than that of PT lamb. The microbial compositions changed faster in the lamb stored in a PT than that stored in a VAC, and microbial community compositions of the late storage period were largely different from those of the early storage period for both the conditions. The findings of this study may guide improve the lamb hygiene and prolong the shelf life of the lamb.

  • Background: This study assessed human papillomavirus (HPV), cervical cancer, and HPV vaccine knowledge and awareness among women in two sub-populations in Nepal - Khokana, a traditional Newari village in the Lalitpur District about eight kilometers south of Kathmandu, and Sanphebagar, a village development committee within Achham District in rural Far-Western Nepal. Methods: Study participants were recruited during health camps conducted by Nepal Fertility Care Center, a Nepali non-governmental organization. Experienced staff administered a Nepali language survey instrument that included questions on socio-demographics, reproductive health and knowledge on HPV, cervical cancer, and the HPV vaccine. Results: Of the 749 participants, 387 (51.7%) were from Khokana and 362 (48.3%) were from Sanphebagar. Overall, 53.3% (n=372) of women were aware of cervical cancer with a significant difference between Khokana and Sanphebagar (63.3% vs 43.0%; p=0.001). Overall, 15.4% (n=107) of women had heard of HPV and 32% (n=34) of these women reported having heard of the HPV vaccine. If freely available, 77.5% of the women reported willingness to have their children vaccinated against HPV. Factors associated with cervical cancer awareness included knowledge of HPV (Khokana: Odds Ratio (OR)=24.5; (95% Confidence Interval (CI): 3.1-190.2, Sanphebagar: OR=14.8; 95% CI: 3.7-58.4)) and sexually transmitted infections (Khokana: OR=6.18; 95% CI: 3.1-12.4; Sanphebagar: OR=17.0; 95% CI: 7.3-39.7) among other risk factors. Conclusions: Knowledge and awareness of HPV, cervical cancer, and the HPV vaccine remains low among women in Khokana and Sanphebagar. Acceptance of a freely available HPV vaccine for children was high, indicating potentially high uptake rates in these communities.

  • The present studwas undertaken to classify and describe the riverside vegetation around Hanchon (36°27’-36°51’N, 128°15’-128°37’E), a tributary in the upper stream area of Nak-tong River, South Korea by methods of the ZM school of phytosociology. As a result the vegetation was divided into twenty three associations and communities belonging to ten classes. Reflecting various human impacts in the past, the associations and communities of the Artemisietea principis were most plentiful there. The vegetation units obtained in the present study were as follows: A. forest vegetation A-1 Fagetea crenatae:Zelkova serrata community, Larix leptolepis community; B. Shrub vegetation B-1 Salicetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea sachalinensis:Salicetum gracilistylae, Salicetum graciliglandis assoc. nov., B-2 Rosetea multiflorae:Stephanandra incisa community, Lycium chinense community; C. Grassland vegetation C-1 Lemnetea minoris:Spirodela polyrhiza-Lemna paucicostata community, C-2 Bidentetea tripartiti:Polygonetum thunbergii, Polygonetum sieboldii-hydropiperis, Panico Polygonetum hydropiperis, Pharagmitetea :Oenantho- Phalaridetum arundinaceae, Phragmitetum japonicae, Miscanthetum sacchariflori, Phragmites australis community, C-4 Artemisietea principis:Artemisia princeps community, Impatiens textori community, Lactuco indicae-Humuletum japonicae, Pueraria lobata-Humulus japonicus community, Pennisetum alopecuroides community, C-5 chenopodietea:Echinochloa crus-galli var. orizicola community, Digitaria adsecendens community, Polygonum nodosum community, C-6 Miscanthetea sinensis: Miscanthus sinensis community, C-7 Plantaginetea:Eragrotis multicaulis-Plantago asiatica community. It is inferred that the endemic vegetation units in the riverside vegetation of Korea are very rare, because most of the vegetation units obtained in the present study are common with those of Japan. Among the above vegetation units, the Salicetum graciliglandis was established as a new association. On the other hand, the associations and communities of classes characterizing the riverside vegetation increased with a decrease of human impacts from the downstream to the upstream in Hanchon, while the number of the naturalized plants was the reverse. Also based on the present phytosociological work, the relation between the vegetation units and their environmental conditions and the restoration ecology and nature conservation of the riverside vegetation were discussed here in detail.

  • Medical education can provide students with an opportunity to encounter marginalized communities and motivate them to become involved with the needs of disadvantaged people. The College of Medicine of The Catholic University of Korea includes a social service program in the medical humanities and social sciences curriculum. The course has lectures on social welfare, human rights, and social service, as well as four days of social service in 'Flower Village,' which is a Catholic social welfare institution. This study analyzes the satisfaction, feedback, and reflection papers of students who completed the social service program and provides an educational model for the medical humanities and social sciences. Students' satisfaction with the program was scored at 4.23 out of 5. A qualitative study of students' reflection papers derived 7 key phrases, among which 'nature and practice of social service,' 'holistic understanding of humans,' 'empathy and communication,' and 'social responsibility' are identified as goals of this program and 'happiness,' 'respect for human life,' and 'compassion' are good indicators of students' compassionate participation. Encounters with marginalized communities within the medical curriculum allows students to serve people with social difficulties and work for the improvement of their living conditions. Students learn to approach social needs with concern and empathy and seek ways to contribute to those communities.

  • A method of conserving the vegetation at Mt. Chonggye was established to persue a practical management of the natural ecosystem by the vegetative composition analysis. As a result, the vegetation of surveyed areas was classified into two communities and four subcommunities in Mt. Chonggye. Potentilla fragarioides var. major community, known as the roadside plant community, distributed near trails under heavy human impacts. Potentilla fragarioides var. major community included two subcommunities : Digitaria sanguinalis-Ambrosia artemisiifolia var. elatior subcommunity and Rhus chinensis subcommunities. In these communiyies, there were many naturalized plant species such as Aster pilosus and Artemisia princeps var. orientalis, known as heliophilous plant. Results indicated that the vegetation had been affected by intensive human activities. It is necessary to control the naturalized plant species such as Aster pilosus for conservation of the ecosystem and nature in this area. Quercus mongolica community, a common coppice woodland in central Korea, was mostly distributed around mountain tops and ridges above 529 m altitute. In the valley where the forests well conserved, the Quercus mongolica community contained the Syneilesis aconitifolia-Hemerocallis lilioasphodelus subcommunity. On the other hand, Potentilla dickinsii subcommunity was dominated in dry rocky ridge areas. In these areas, however, the vegetation and forest soil was not properly managed for conservation.

  • The purpose of this study is to examine a potential association between community factors and the establishment of Local Healthy Family Support Centers (LHFSCs). Community factors were population size, community size, local finance independency, number of workplaces per 1,000 people, number of colleges, political party affiliation of mayor, and political party affiliation of congressman. Data of this study were collected from the census indicators of 222 communities from 2004 to 2014 and analyzed by frequency, mean, geographical information system mapping, and the binary logit analysis. The results of this study are as follows. First, LHFSCs are less likely to be established in communities in the provinces of Gangwon, Chungbuk, and Gyeongbuk. Second, the population size was positively related to the establishment of LHFSCs. Third, finance independency was positively associated with the establishment of LHFSCs. Forth, a mayor was more likely to establish LHFSCs if they were affiliated with the ruling conservative political party. However, the establishment of LHFSCs was not affected by other factors such as community scale, number of workplaces per 1,000 people, the number of colleges, and party affiliation of congressman. Thus, the conclusion suggests family policy implications to improve the geographical imbalance of LHFSCs based on the analysis results.

  • As our lifestyles have changed due to rapid industrialization and urbanization, new social and communication problems have been caused and there have been lots of discussion on regional communication. For communities to become alternatives with realistic meanings in this changed society, considerations on social and spatial conditions are needed. Therefore, public space which works as a device of physical environment for activation of communities needs more active changes which encourages social communication. In respect to the activation of communities, the following suggestions are given: First, physical devices of a urban plaza should be arranged to support various programs presented along with consideration of human behaviors as users. Second, fundamental facilities of the plaza should accommodate various activities through connections with programs and commercial space. Third, when cultural and historical characteristics of the community are understood, the plaza can form regionality and symbolism through artistic representation. And users can form the identity of community. Fourth, transportation facilities should be separated from or coexist with areas of passengers and the plaza should have its own identity through symbolic sculptures.

  • The purpose of this study is to identify difference in motivation of move to senior cohousing communities in Sweden during 10 years between the year of 2001 and 2010 by a longitudinal study. Questionnaire survey was used for the study. 313 data were collected from 12 senior cohousing communities, which were established by residents-initiated process. It includes 8 of Senior g${\aa}$rden cohousings in 2001 and 4 of +40 cohousings in 2010 nationwide in Sweden. The result indicates that there are significant differences in motivation of move to senior cohousing between 2001 and 2010. Comparing motivation of move to senior cohousing during 10 years, respondents of 2010 focus more on social merits than practical merits of cohousing as they move to cohousing communities. They stress more to the reasons as good contacts with neighbors, mutual supports, sharing common activities and getting rid of loneliness rather than burden of housing and garden management, and universal-designed house. The result of this study reveals motivation of move to senior cohousing has been changed during 10 years in Sweden.
