Purpose: The purpose of this research is, by investigating organizational characteristics, types of nursing organizational culture and team effectiveness in ICU, to ascertain the type of nursing organizational culture and the organizational characteristic that can improve the team effectiveness. Method: The research targeted 427 nurses from 33 ICUs of 14 general hospitals which have more than 250 beds and the data were gathered by using self-report questionnaires from April 10, 2003 to April 24, 2003. For this research, the following tools were used; the tool for measuring organizational characteristics and organizational cultures and the tool for measuring team effectiveness. Result: The most significant nursing organizational characteristic in ICU is the centralization. The organizational culture in ICU is generally rank-oriented culture. There was a significant difference (p<.01) in four types of organizational cultures; relation-oriented, innovation-oriented, rank-oriented and task-oriented. Verifying influence power of organizational cultures upon team effectiveness of ICU, relation-oriented culture had 49.2% of an influence upon team effectiveness, innovation- oriented and relation-oriented culture had 60.4% of an influence, and rank-oriented, innovation-oriented and relation-oriented culture had 61.2% of an influence. The organizational culture profiles according to the types of nursing organizational cultures in 33 ICUs were found by a cluster analysis. They were classified into five culture profiles; strong balance culture profile, weak balance culture profile, innovation-oriented and task-oriened culture profile, strong relation culture profile and strong rank culture profile(p<0.5). According to me organizational culture profiles, a significant difference of team effectivenesses(coworker satisfaction, team performance perception, team satisfaction and team commitment) was found(p<.01). The strong balance culture profile had the best team effectivenesses. Conclusion: For nursing culture management, a nursing administrator should identify the relevant nursing organizational culture at first by utilizing an innovative team-leader. After identifying the organizational culture, the administrator should make strategic plans and practices that can distinguish good organizational cultures to be expanded from ones to be sublated so that a strong balance culture can be developed.

Tissue engineering has been extensively investigated and proffered to be a potential platform for novel tissue regeneration. The utilization of mesenchymal stem cells (MSCs) from various sources has been widely explored and compared. In this regard, MSCs derived from bone marrow have been proposed and described as a promising cell resource due to their high yield of isolated cells with colony-forming potential, self-renewal capacity, MSC surface marker expression, and multi-lineage differentiation capacities in vitro. However, there is evidence for bone marrow MSCs (BM-MSCs) both in vitro and in vivo from different species presenting identical and distinct potential stemness characteristics. In this review, the fundamental knowledge of the growth kinetics and stemness properties of BM-MSCs in different animal species and humans are compared and summarized. Finally, to provide a full perspective, this review will procure results of current information studies focusing on the use of BM-MSCs in clinical practice.

Swietenia mahagoni is one of the commercial timbers in Indonesia. Mahogany heartwood is an important characteristic as it relates to the natural durability and aesthetics of the wood. Lipophilic extractives are known to be involved in the heartwood formation process. Therefore, this study aims to determine the lipophilic compounds associated with heartwood formation. The n-hexane extract from sapwood and heartwood samples (1 to 5 years) was analyzed by gas chromatography-mass spectrometry. The results showed that the content of n-hexane extract ranged from 0.76% to 2.45% based on dry wood. The main group of compounds identified in the lipophilic fraction consisted of sterols (β-sitosterol, stigmasterol, campasterol, and cyclolaudenol), fatty acids (palmitic, oleic, linoleic, and stearic acid), and hydrocarbons (pentadecane, 1-octadecane, hexadecane, cyclotetracosane, cycloeicosane, and cyclooctacosane) after heartwood formation. In addition, the hydrocarbon fraction was the largest, followed by sterols, fatty acids, and 1-heneicosanol. In the radial variation, the distribution of fatty acids was greater in the sapwood than in the heartwood (4-year-old). However, the reverse pattern was found at the age of 5 years. The lipophilic fraction was generally more abundant in the heartwood compared to the sapwood, especially at 5 years of age, with much higher levels than when the heartwood was forming (4 years). These findings show that when the heartwood formation begins, the lipid composition was not fully metabolized at the beginning of heartwood formation compared to 5-year-old trees.

This study analyzes patenting practices in the pharmaceutical industry and the impacts of sequential innovation. The main argument of the research is that strategic patenting is common in the pharmaceutical sector and it is legal within the context of patent law. However, when these practices have negative effects on the competition process post-grant, the practices that are legal under patent law may come into conflict with antitrust laws, which are not applied. The study brings into question whether sequential patenting practices characteristic of the pharmaceutical industry encourage or discourage innovation, and moreover, the overall functionality of the patent system. Ultimately, the functionality of the patent system creates market incentives that neglect consumer, i.e., patient, welfare; potential solutions to deal with the shortcomings are discussed.

Recently, knowledge management(KM) has attracted increasing attention from academicians and practitioners alike. Amongst others, technological knowledge(TK) is considered principal asset of KM and R,&D organization of private firms selves as primary actor of KM. It is also noted that the notion of sectoral pattern of innovation highlights idiosyncratic differences across industrial sectors in terms of TK management. That is, knowledge contents, knowledge generation and How pattern are considerably different among industries. This paper first analyzes the correlation between structural of R&D organization and industrial(sectoral) type to identify the dominant structure of R&D organization for each industry. Second, sector-specific architectures of TK management system are proposed. According to structural characteristic of R&D-organization type, test-practice forms of TK management system are suggested in terms of such factors as knowledge contents(technology information), knowledge generation activities, and knowledge storage/retrieval modes.

This narrative review describes genomic characteristic, serotyping, immunogenicity, and vaccine development of Streptococcus pneumoniae capsular polysaccharide (CPS). CPS is a primary virulence factor of S. pneumoniae. The genomic characteristics of S. pneumoniae CPS, including the role of biosynthetic gene and genetic variation within cps (capsule polysaccharide) locus which may lead to serotype replacement are still being investigated. One hundred unique serotypes of S. pneumoniae have been identified through various methods of serotyping using phenotypic and genotypic approach. The advantages and limitations of each method are various, emphasizing the need for accurate and comprehensive serotyping for effective disease surveillance and vaccine targeting. In addition, we elaborate the critical role of CPS in vaccine development by providing an overview of immunogenicity, ongoing research of pneumococcal vaccines, and the impact on disease burden.

As the population ages, the importance of effective bone disease treatments is increasing, highlighting the role of bone grafts. Bone grafts are categorized into natural (autografts, allografts, xenografts) and synthetic (ceramics, polymers). Natural grafts have excellent regenerative abilities but pose biological risks, while synthetic grafts are biocompatible but less effective in regeneration. Various studies aim to enhance the safety and efficacy of bone grafts, significantly altering their surface properties. This review examines these studies and the resulting surface changes, aiming to guide future research and clinical applications.
