This study evaluates common activity and quality of life in Swedish cohousing units to examine whether Swedish cohousing functions properly or not. A questionnaire survey was fulfilled during the autumn of 2010 in G$\ddot{o}$teborg Sweden. The subjects of study were 12 of 44 cohousing units in Sweden that included 4 of the +40 cohousing and 8 of the mixed-age cohousing. A total of 242 of 353 distributed questionnaires were collected (68.6%) and analyzed by SPSS statistical program. The findings are as follow: 1) General characteristics of the respondents are that they are mostly healthy, evenly aged from age 50s to 70s and highly educated with significant proportions of academics and civil workers. There are more females than males and more singles than cohabitants. 2) The most frequent and preferred common activity is a common meal followed by a coffee meeting. A common dinner, the 'hub of living together' is held almost every day or at least a few times a week. A common meal is considered one of the most important activities because of practical and social advantages in that residents can save time and cooking costs as well as engage in social contact. Referring to evaluation of frequency and content of common activity, more than a half of the respondents prefer the current situation. 3) All of the variables (except health conditions and education level) affect participation in common activity with statistical significance. 4) Most of the respondents indicate a high level of life satisfaction and are willing to recommend others move to cohousing. They agree that there is more mutual support among residents in cohousing units than in a conventional community. In conclusion, Swedish cohousing units function successfully as they have pursued intentional community ideology and most of the residents are proud of their current living situations.

Antioxidant activity of the extract fractions from leaves, stems, roots and flowers of Cirsium pendulum Fisch. was investigated. The results showed the greatest antioxidant activities in leaves by Rancimat, TBA and DPPH methods. Extracts of common thistle plants dose-dependently increased DPPH free radical scavenging activity, The extract from flowers and its hexane fraction showed the strongest antioxidant activity. HPLC analysis showed that BuOH fraction of the leaves had the highest amount of antioxidant chlorogenic and p-coumaric acids at 5.38 and 9.71 mg $100\;g^{-1}$, respectively. It implies that common thistle plants had potent antioxidant activity, and their activities were differently exhibited depending on plant part and solvent fraction.

The present study examined whether enjoyable couple activity and common dyadic coping as daily positive couple interactions have direct or indirect effects on marital satisfaction through the mediation of sexual intimacy among urban Chinese women in the early years of marriage. The subjects were 182 urban women born under the one-child policy, who live in Heilongjiang, Anhui and Beijing provinces of China, and have been married up to six years. Data were collected using a self-administered questionnaire. We conducted a hierarchical multiple regression analysis in SPSS software and tested the significance of the mediation effects using bootstrapping method in Mplus software. The results of the study are as follows. First, both enjoyable couple activity and common dyadic coping had positive direct impacts on urban Chinese women's marital satisfaction and positive indirect impacts on marital satisfaction via sexual intimacy. Second, enjoyable couple activity was the strongest predictor of marital satisfaction, followed by common dyadic coping and sexual intimacy. The path model explained 48% of the variance in marital satisfaction. The results suggest that enjoyable couple activity, common dyadic coping, and sexual intimacy should be considered in the design of interventions to enhance urban Chinese women's marital satisfaction in the early years of marriage.

The purpose of this study was to examine the application of the Activity-based Costing(ABC) system to analyze the cost of nursing services in the delivery room in a major medical center.The results of this study are as follows;1. In order to calculate the cost of nursing activities, 67 activities of staff nurses on a delivery room were identified and classified as direct nursing activities(45.2%), the indirect activities(32.1%), general management activities(13.9%) and others(8.8%).2. Nursing cost in the delivery room was classified into activity cost(29.9%) and common cost(70.1%). Activity cost involved direct activity cost of staff nurses. The common costs were categorized into indirect activity & general management cost of staff nurses, management cost of the head nurse and activity cost of assistants.3. The final cost objects of nursing services in the delivery room were nursing service for women who had normal vaginal deliveries and nursing service for women who had preterm labor.The total cost of nursing service for a woman who had a normal vaginal delivery was 165,710 won (100.0%). The cost incurred through direct activity cost of staff nurses(58,242 won, 35.1%), indirect activity & general management cost of staff nurses (55,643 won, 33.6%), management cost of head nurse (16,211 won, 9.8%), activity cost of assistants (35,614 won, 21.5%).If the number of days of hospitalization was presumed to be 14 days, the total cost of nursing service for woman who had preterm labor would be 1,845,901 won (100.0%). The cost incurred by direct activity cost of staff nurses in the activity cost (341,349 won, 18.5%), indirect activity & general management cost of staff nurses in the common cost(779,002 won, 42.2%), management cost of head nurse(226,954won, 12.3%), activity cost of assistants in the common cost(498,596 won, 27.0%).In this study, the cost of the nursing services in the delivery room was calculated based on the ABC system. The results of this study showed that resources are assigned to the nursing activities in the delivery room and the mechanisms for assigning the cost of activities for nursing services.

Possible mechanism of decreased catechol-O-methyltransferase (COMT) activity in cholestatic rat liver was studied. Hepatic and serum COMT activities were determined from the experimental rats with common bile duct ligation (CBDL). The Michaelis-Menten constants in this hepatic enzyme were also measured. The activities of cytosolic, mitochondrial and mircosomal COMT as well as their Vmax values were found to be decreased significantly in CBDL plus taurocholic acid (TCA) injected group than in the control group, such as CBDL alone groups. However, their Km values in the experimental groups did not vary. Serum COMT activity increased slightly in the CBDL plus TCA injected group than in the control group. The above results suggest that TCA represses biosynthesis of the COMT in the liver. The elevated activity of the serum COMT is believed to be caused by the increment of membrane permeability of hepatocytes upon TCA mediated liver cell necrosis.

The Korean common bean (Phaseolus vulgaris L.) has been receiving increased attention as a functional food. The objective of this study was to reveal the phytochemicals genetic variation and antioxidant activity of 209 Korean common bean landraces. Antioxidant activity was evaluated with the DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate), ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid), ferric reducing antioxidant power (FRAP), and superoxide dismutase (SOD) assay. Antioxidant activities among common bean accessions showed wide variation. Four flavonoids (kaempferol, myricetin, quercetin, and naringenin) of the 209 Korean common bean landraces were measured using HPLC. Among them, kaempferol had the highest phytochemicals compared to the other three flavonoids. Using the relative antioxidant capacity index (RACI), it was found out that the IT104587 had the highest antioxidant activity. Meanwhile, in clustering analysis, the Korean common bean landraces were classified into three clusters. Among them, cluster II contained 64 landraces with higher antioxidant activities and phytochemicals than the other clusters, except DPPH. The results could provide information on the valuable Korean common bean landraces for the development of new common bean varieties.

Our society has been dominated by the Dilemma Theory that rational individuals cannot get out of the 'Tragedy of the Commons' without helps from state or market. However, many empirical researches have discovered cases that common pool resources could be managed by cooperative methods of community. Based on the possibility of managing common pool resources by residents' cooperation/solidarity revealed by the recent case researches, this study aims to seek for the theoretical basis to prove it. Generally, public policies are carried forward based on the theoretical basis of the relevant social issues. The objective of this study is to suggest the new direction of policies related to domestic common resources through the researches on community's role in managing local common pool resources represented as "scenic spot". For this, it aims to reveal the influence of community activity on behavioral intention of local common pool resources, by drawing/quantitatively measuring measurement items of local residents' community activity on top of attitude, norms, and behavioral control suggested by the existing Theory of Planned Behavior. The results of this study are as follows; 4 factors such as attitude toward behavior, subjective norm, perceived behavior control, and community activity were all factors that influenced intention to manage.

Inquiry activity contents presented at a chapter on natural environment and our lives in 6 science textbooks of the middle school were analyzed based on kinds of the inquiry Loaming classified by textbook. The number of inquiry activity subjects showed severe variation as mean value was 8.3${\times}$3.7 ranged from 4 to 15. Moreover, textbooks had little common point among each other as the percentage of subjects appeared together in the textbooks more than 3 kinds, 50% of total ones investigated, was just 26.3%. Data interpretation occupied significant position in the inquiry activity as 42% of total activity contents, whereas observation and experiment (or survey) did slight part of the activity as 10% and 16%, respectively even though they are main factors of science education. A model for field education based on the reasonable common subjects was prepared in the Gildong ecological park located In the eastern fringe of Seoul as a plan in order to solve the problems.

In Korea, a movement for forming intentional communities is gathering people's interests to improve individualistic living environment, and to create a humanistic lifestyle. However, it is difficult to say if its management is successful or not, because intentional community is just in the experimental stage in Korea. The purpose of this study is to identify actual condition of residents' participation in forming process, shared activities in their daily lives, residents' regulation, common facilities and its management in order to offer basic information for revitalization of intentional communities in Korea. 7 intentional communities including eco-friendly villages, religious communities and a cooperative housing community were collected as the study objects. Upon analysis, those communities were divided into two groups according to their purpose of establishment; "HC (Housing-life focused Community includes cooperative housing community and eco-friendly community)" and "IC (Ideology focused Community includes ideology community and religious community)" in order to identify difference in residents' participation between the two groups. In-dept interviews with representatives of 7 intentional communities by a structured questionnaire were used as study method. The findings of this study are as follows; In general, more active residents' participation is identified in ICs than in HCs. There is no common house, which is considered as essential in intentional community, in HCs, while it was facilitated in all ICs. Role of leader seems more important in ICs than in HCs. About the ownership of housing and land, private owned is common in HCs, while community owned is common in ICs. Shared activities and residents' regulations are evidently less in most HCs than in ICs. Furthermore, in order to run a community sustainable, it is crucial to encourage sense of community among residents, and developing common house and activity programs. Common house design, which can promote proactive residents' participation in shared activity should be studied fitted to Korean circumstances. Above all, proactive participation in the shared activities is one of the most important factors in intentional community.

Through in vitro screening for biocontrol agents (BCAs) against Streptomyces scabiei causing potato (Solanum tuberosum) common scab, 19 streptomycete and 17 fungal isolates with antagonistic activity were selected as BCA candidates. For the selection of BCA candidates which are highly resistant to 10 kinds of antibiotics or pesticides, chemical susceptibility testing was initially performed in vitro. A remarkable degree of variation in susceptibility to antibiotics or pesticides was observed among the isolates tested. Streptomycete A020645 isolate was highly resistant to all the tested chemicals except neomycin up to 5,000 ppm. On the other hand, out of 36 antagonistic microbes subjected to in vivo pot tests using cultivar Daejima, four streptomycete isolates namely, A020645, A010321, A010564, and A020973, showed high antagonistic activity with >60% and 55% control value, respectively, and high chemical resistance to 10 kinds of chemicals. Therefore, these isolates were selected as potential BCAs for the control of potato common scab.
