The social capital of an organization is recognized as the origin of the knowledge capital creation, and it becomes the mechanisms which explain the interaction of members or which accelerate the behavior of the members to attain the goal of an organization (Park, 2001; Jang et al., 2011). Lots of researches show that this causal relationship empirically exists. Social capital and knowledge capital of an organization are one of the most important competitive advantages that a company needs. They are also the main dynamic drivers of the innovation activity. This study analyzes the relationship and examines the impact and role of an organization's social capital on intellectual capital and innovation activities in an organization. In other words, the main purpose of this study is to analyze the impact of social capital on the intellectual capital and innovation activities of, in particular, China local companies. This study empirically analyzed the survey data collected from the employees of the companies located in China. Our empirical results of this study showed that social capital has significantly causal effects on intellectual capital partially and also showed the intellectual capital has significantly positive effects on the innovation activities partially.

Cibotii Rhizoma, the dried rhizome of Cibotium barometz J. Smith (C. barometz), has long been used to treat bone or nervous system disorders. In this regard, we isolated three main phenolic compounds, onitin-4-O-${\beta}$-D-glucopyranoside (1), irisdichototins E & F epimeric mixture (2), and protocatechuic acid (3) from C. barometz methanol extract. In addition, we screened their antioxidative activities by DPPH, ABTS radical, and superoxide scavenging assays. Among these three compounds, irisdichototins E & F and protocatechuic acid showed strong antioxidant activities. Also, the antioxidant activities of the C. barometz extracts were proportional to the contents of irisdichototins E & F and protocatechuic acid, thus these two phenolic compounds could be main active compounds of C. barometz. In addition, onitin-4-O-${\beta}$-D-glucopyranoside is considered as a marker compound of C. barometz because this compound is specifically contained in C. barometz which belongs to Pteridophyta order. A rapid analysis method for the simultaneous determination of phenolic compounds was also developed by UPLC (Ultra Performance Liquid Chromatography). Using the developed method, the two active compounds (irisdichototins E & F and protocatechuic acid) and a marker compound (onitin-4-O-${\beta}$-D-glucopyranoside) were successfully quantified in 14 commercial samples that were collected from different regions.

The purpose of this study was to find the role of participation in common activities and satisfaction with common space in a tentative housing adjustment framework for Swedish cohousing residents, applying the housing adjustment behavior model of Morris and Winter (1978, 1996). The data used for this research were a subset of data Choi and Paulsson (2011) surveyed from 12 Swedish cohousing units. Number of 216 cases whose age was 40 and over were selected and analyzed with Pearson correlations and hierarchical linear regressions by SPSS. The regression analyses included four main concepts as endogenous variables, which were participation in common activities, satisfaction with common space, overall life satisfaction, and intention to move out. The results showed that participation in common activities raised satisfaction with common space and overall life satisfaction but reduced intention to move out. Meanwhile, satisfaction with common space diminished intention to move out but did not impact overall life satisfaction. When overall life satisfaction was added to the final regression model, the direct impacts of security reasons, participation in common activities, and satisfaction with common space on intention to move out disappeared. It may be concluded that participation in common activities and satisfaction with common space acted as intervening variables in the tentative cohousing adjustment framework. Even though this study leaves further research on specifying the framework, it may be noteworthy as a first attempt that explains the flow of main concepts. This study may broaden the possibility of empirical studies to develop an analytical path model of housing adjustment for cohousing residents.

The paper considers the main processes of evolution and convergence of information and communication technologies, which have a permanent source for creation and introduction of innovations in learning and education. The modern scientific and technological revolution gives new features to all modern activities, including activities in the sphere of education, influencing it and transforming its phases, form and content, and perhaps understanding in general. Consequently, general understandings about the essence of the provision of educational services and their technological support are also being transformed. Note that, according to scientists, convergence is a new determinant of the development of society, and evolution is a multidimensional natural process of development (becoming).

This article is concerned with the importance of organisation management and its characteristics in business performance in SMEs, and tested by four main aspects: managerial strategies, organisational structure, leader behaviour, and R&D activities. These relationships were tested with questionnaire data from a random sample of 87 firms. Results from simple statistics on each issue showed that SMEs have focused on the corporate growth and management goals, the democratic leadership, decentralisation in organisational structure, and the technology development plans. Results from correlation analyses not only found significant relationships between managerial strategy and R&D activities but also showed differences in R&D activities according to structural status or leadership style, respectively.

Ligusticum chuanxiong (Umbelliferae) is a perennial herb that has been used for invigoration of blood in Korean traditional medicine. It is especially important in gynecological therapy of amenorrhea and dysmenorrhea. In this study, the essential oil of L. chuanxiong was obtained by steam distillation and its main components of L. chuanxiong, Z-ligustilide and butylidene phthalide, were isolated by silica gel column chromatography. We investigated the cytotoxic effects of the essential oil fraction of L. chuanxiong and its main components on MCF-7, HeLa and SK-Hep-1 cell lines by measuring the number of surviving cancer cells after treatment through direct cell counting and MTT analysis, and by examining the morphological changes under the microscope. The essential oil from the rhizomes of L. chuanxiong and its main components showed significant cytotoxic activities for all three tested cell lines. We also observed morphological changes of shrinking and blebbing in the membranes of the three cell lines, depending on the concentration of L. chaunxiong oil or its main components.

This study investigates the relationships of total quality management (TQM), organizational learning (OL) activities and business performance and examines the partial mediation effect of OL activities on business performance in Korean industrial manufacturing setting. Main target sample firms were all manufacturing companies listed in the Korea Composite Stock Price Index (KOSPI) and 206 firms participated. This study theoretically develops a conceptual model with 3 hypotheses regarding how TQM practices influence OL activities and how the OL activities partially mediate between the TQM practices and business performance. To examine these hypotheses, Structural Equation Modeling (SEM) was employed and an alternative model which includes a path between errors of leadership factor and OL construct was developed. The findings are TQM practices cannot directly influence business performance but indirectly impact business performance through OL activities. This study found that OL activities playa role as firms' critical competency to improve business performance.

Aloe vera L.(Aloe barbadensis Miller) has been used for many centuries for various medical, cosmetic and neutraceutical purposes. The gel of A. vera was reported to exert numerous biological activities including wound healing, immunomodulatory, anti-cancer, anti-inflammatory, anti-bacterial, anti-viral, anti-diabetic, and anti-psoriasis activities. Acemannan, found predominantly in the inner leaf gel of A. vera, has been identified as the main active ingredient exerting diverse biological activities. In this review, we summarized the recent findings on the immunomodulatory activities of acemannan. Studies that used purified acemannan demonstrate that acemannan exerts immune-stimulating, anti-cancer, anti-viral, and hematopoiesis-increasing activities. In addition, it is being clear that most of these activities of acemannan are mediated primarily by activating professional antigen presenting cells such as macrophages and dendritic cells.
