The spontaneous self-organization of amphiphilic molecules into complex aggregates was undoubtedly an important factor in the emergence of life on earth. We study the parameters governing the self-organization of a simple amphiphilic model system using electron cryomicroscopy of ice-embedded specimens in combination with extensive data analysis. Different stable helices can be generated reproducibly by changing the parameters controlling the molecular aggregation process. The repeating units of the helical aggregates in the micrographs can be found by multivariate statistical image analysis techniques, and these two-dimensional projection images suffice for calculating the three-dimensional density distribution of the fibers. We present a typical structure consisting of a narrow stack of compartmented bilayers twisted into a left-handed helix. Our new techniques directly elucidate the three-dimensional structure of helical assemblies, and can complement or replace diffraction-based approaches.

The purpose of this study is to verify the relationship between mission-oriented Command, organization efficiency, organization culture of 626 field officers in JFMU. Firstly. the study found that decision making in the relationship between mission-oriented command and organization efficiency had negative effect on job satisfaction. Planning and trust lead to positive effect on job satisfaction and organizational commitment and no significance in self decision. Secondly, mission-oriented command may differ depending on the types of organization culture and organization culture has positive effect on job satisfaction and organizational commitment. Thirdly, mission-oriented command has some effect which derives from its impact on organization efficiency that also effects rational culture and rank hierarchy culture. These study results suggest different measures in terms of practice and policy. Firstly. within the military organization, precise communication will lead to job satisfaction without unnecessary overload of communication. Also. we have rationale culture, agreement culture and rank hierarchy culture forming our organization culture. There is a need to apply elements of mission-oriented command depending on the types of organization culture. Secondly, to maximize organization performance through mission-oriented command, we have to strengthen the rationale and rank hierarchy cultures and especially introduce development culture which should be established within the military organization.

Purpose: The purpose of this study was to examine the relationship between lymphedema self-care management and quality of life in breast cancer patients with mastectomy and lymphedema. Methods: One hundred and eighty-six breast cancer patients with mastectomy and lymphedema (n=186) were recruited at a medical center located in Seoul. The levels of lymphedema self-care management and quality of life were measured by the scale for measurement of practice in lymphedema self-care management, European Organization for Research and Treatment of Cancer-Quality of Life Core 30 (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire Breast Cancer Module (EORTC QLQ BR23), respectively. Data were analyzed with SPSS 18.0 program. Results: There were statistically significant correlations between lymphedema self-care management and general health status/quality of life in mastectomy patients with lymphedema (r=.30, p<.001). The physical function score of cancer related function scale (r=-.15, p=.033), fatigue score of cancer related symptom scale (r=.15, p=.036), systemic side effect score of breast cancer related symptom scale (r=.45, p=.034), and upset by hair loss (r=.27, p=.004) were significantly correlated with quality of life. Conclusion: The findings suggest that these significant factors should be considered when caring for lymphedema patients.

Purpose: This study was designed to identify a path model that anticipates the interpersonal competence of nurses by anticipating factors that explain interpersonal competence within an organization, and analyzing the effects of these factors. A hypothetical model was formulated based on a literature review of interpersonal competence. For the study, influential factors were divided into two variables: exogenous variables including communication style, coaching leadership, and social support, and endogenous variables of self-efficacy, job satisfaction, and organizational commitment. Methods: The sample included 202 hospital nurses. Data were collected through questionnaires and analyzed using SPSS and AMOS. Results: The overall fitness was good ($x^2=74.707$, p<.001), d.f=19, $x^2/df=3.932$, GFI=.940, AGFI=.826, RMR=.009). Social support, self-efficacy, horizontal communication and organizational commitment directly affected the interpersonal competence of the nurses, and informal type of communication, horizontal, upward communication and coaching leadership indirectly effected the interpersonal competence of the nurses. Horizontal communication, social support, self-efficacy, and organizational commitment explained 46.5% of the variance in interpersonal competence of nurses. Conclusion: Based on the study results, nurses in hospitals need informal types of communication, horizontal, upward communication and coaching leadership to increase their interpersonal competence.

Learning procedure in the neural network is updating of weights between neurons. Unadequate initial learning coefficient causes excessive iterations of learning process or incorrect learning results and degrades learning efficiency. In this paper, adaptive learning algorithm is proposed to increase the efficient in the learning algorithms of Self-Organization Neural Networks. The algorithm updates the weights adaptively when learning procedure runs. To prove the efficiency the algorithm is experimented to classification of strokes which is the reference handwritten character. The result shows improved classification rate about 1.44~3.65% proposed method compare with Kohonan and Mao's algorithms, in this paper.

The objective of this study was to investigate the developmental level of Rural Women Leaders Federation(RWLF) which is one of the major rural women`s association in Korea. The writers designed organization measurement tool based on the reviews on the related studies and gather data from 191 memberships of RWLF through the mail questionnaire and interviews. The major findings were as follows; First, the findings shows us this organization as transition period from identification stage to expanded growth stage in developmental stage of rural women's organizations. Second, this organization focus on share of members decision making and leadership style rather than organization`s vision, strategy or organization level. In other words, this organization focus on human relations aspect rather than internal aspect of organization system. Third, this organization has high level of social evaluation of the organization, even if it has low level of personal compensation or individua's social performance. In conclusion, as long-term view-point, it is needed to help them to promote their self-control of survival ability to improve organization's vision, strategy, differentiation for achieving organizational goals. And it also needed to prepare educational programs to increase Rural Women's leadership capability understanding of organizational characteristics and its operation abilities.

Facing the globalization of world economy, intense market competition, radical change of information technology, firms are obliged to create a new type of organizations characterized by flexibility and adaptability to new and dynamic environments. This paper reviews the theories of complexity in physics briefly and discusses the implications of them on the management of business organizations. It analogizes the core concepts from complexity theories such as cooperative phenomena, self-organization, adaptation, positive feedback, and butterfly effect, and attempts to identify their implications on business management. Particularly, it suggests principles of 'Fractal' management which apply the fractal structure to the business organization.
