Concurrent construction offers considerable improvement for shorten the project duration of its production process. Therefore, standardized concurrent construction is widely applied in building construction projects. However, resources planning for standardized concurrent construction project is manually developed by construction manager. This practice is not effective since it is time-consuming and error-prone for managers to identify all project-specific information, distinguish different activity-resource types, interpret these types and analyze how they affect resource allocated on an ad hoc basis. Therefore, this research investigates the opportunity for leveraging activity modeling to enable automated resource planning for standardized concurrent construction during project development, with identifying the characteristics of construction activities under standardized concurrent planning and determining the activity-resources types that affects resource planning. Both will function as a basis for modeling these construction activities in a computer-interpretable manner and for automation in resource planning.

The purpose of this empirical study is to examine the effects of middle-aged married women’s attitude and activity for leisure upon their life satisfaction. The samples were composed of 388 married women between 40 years and 59 years old, selected by age and local distribution. As the major findings of this study, the most decisive factors to enhance the life satisfaction are found as follows: First, the behavioral factor among the leisure attitudes is most affective to highten the life satisfaction. Second, self-development activity, friend-making activity and home-oriented activity are the most decisive factors in the category of participation rate of leisure activities. Third, in the types of leisure activities, leisure activity with husbands is the most affecting. Also, the economic factor of the samples was the most significant factor to affect the life satisfaction. The findings of this study provide some implications regarding the policies on the leisure facilities, leisure education programs, the governmental and social supporting systems, and the spontaneous efforts of women themselves to enhance the quality of life of the middle-aged married women.

Leisure time may be used to participate in activities alone, with family, or with other people. The purpose of this research was to identify types of leisure time with whom and determinants of the types. The data source for this research was the '2009 Time Use Survey' conducted by the Korea National Statistical Office (KNSO). The item 'people involved in each activity' was surveyed for the first time by KNSO in 2009. 3,712 diaries completed by married adults aged 20 to 59 years were analyzed using chi-square, cluster analysis, and logistic regression analysis. Leisure time with whom was classified into four types based on three categories of leisure time (alone, with family, with others): "individual-oriented leisure," "family-oriented leisure," "others-oriented leisure," and "vulnerable leisure." These types were different by various socio-economic variables. And gender, work time, the presence of preschool children, and household type were identified as important determinants for the types.

The purposes of this study were to analyze the types of leisure activities and level of leisure satisfaction with practice of a five-day workweek, and examined the relationship between leisure satisfaction and job satisfaction. The data were based on the questionnaire with 264 working employee residing in Seoul. The results indicated that the most frequently participating activities were sports, use of media, loaming activities in order. And there were no significant differences in types of leisure activities between 5 day working employees and 6 day working employees. Secondly, general level of leisure satisfaction was the highest when participating religious activities. Thirdly, it was found that only social satisfaction was positively related to job satisfaction, and social satisfaction influenced job satisfaction. Further discussions and implications were discussed.

This paper investigates the determinants of the firm's decision to carry out innovative activities in terms of the resource-based view(RBV) in strategic management. Two types of resources are distinguished: tangible(financial autonomy, firm size, capital intensity) and intangible(human resource, entrepreneurship, and commercial resource). R&D intensity and patent statistics are used as proxies for innovative activity. Specific hypotheses about their effect on the probability of a firm carrying out innovative activities are derived and tested on a sample of 337 listed firms in Korean manufacturing industry for the year 1999, using the logistic regression model. Empirical findings suggest that firm size and human resource are the main determinants of firm's internal innovative activities. The results show that the hypotheses concerning financial autonomy, debt ratio, capital intensity, entrepreneurship, and commercial resource are rejected.

Time pressure and financial burden have been reported as the main constraints on leisure participation. The purpose of this study was to explore a typology of leisure constraints, investigate the characteristics of leisure constraint types, and analyze the differences in leisure participation by the types of leisure constraints for married employees. The data source for this research was the 2009 Time Use Survey conducted by the Korea National Statistical Office (KNSO). Married employees aged 20 to 59 years completed 13,476 time diaries (7,984 for male, 5,492 for female), which were analyzed using chi-square, cluster analysis, and ANOVA analysis. Leisure constraints were classified into five types in two categories, working time per week and personal income for both males and females respectively. The three types for both males and females were time-income constraints, income constraints, and general constraints, with an additional type for men, $time^+$-income constraints, and an additional type for women, time constraint. The most common type was general constraints, for both males and females. Each type was further differentiated by the following socio-economic variables: age, educational level, job type, and weekly day-off. The study found that participation in study, sports, and religious activities varied with the types of leisure constraints.

Background: This study examined the use of new bio-materials with enhanced value and functionality, which were derived from fermented wild ginseng cultures. Methods and Results: To examine the antioxidant activity associated with biological functions, radical scavenging analyses (2,2-diphenyl-1-picrylhydrazyl, DPPH and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid, ABTS) and superoxide dismutase (SOD)-like activity analyses were conducted. Furthermore, the total phenolic and flavonoid contents of wild ginseng fermented with microorganisms (Leuconostoc mesenteroides, Bacillus circulans, Bacillus licheniformis and B. subtilis subsp. inaquosorum) were evaluated to determine the antioxidant activity increment. Regarding ginseng fermented with B. licheniformis, values of $70.6{\pm}1.4%$, $44.3{\pm}1.7%$, and $88.4{\pm}1.3%$ were measured using DPPH, ABTS, and SOD-like antioxdiant activity analyses, respectively. The total phenolic content in ginseng fermented with B. licheniformis was $184.5{\pm}0.9{\mu}g{\cdot}GAE/m{\ell}$, and the total flavonoid contents was $108.5{\pm}1.8{\mu}g{\cdot}QE/m{\ell}$ in ginseng fermented with L. mesenteroides. Conclusions: Of the four types of lactic acid bacteria examined, the use of B. licheniformis to ferment ginseng resulted in greatest increase in antioxidant activity. Therefore, ginseng fermented by microorganisms might be used to produce functional bio-materials.
