In modern times, pluralistic social phenomena in which various values are pursed and recognized appear. The modern society called hyper-connected, intelligence information and zero marginal cost society in which shared value is commonly emphasized faces a paradigm shift to shared society system. In particular, sharing-based activities related with intelligence information sectors more prominently emerge in the high-tech informatization which has been accelerated. The purpose of this study is to understand design factors related with how attribution of the sharing culture is expressed in library spaces and examine how sharing infrastructure is established in users' spaces. As a research method, it initially conducted theoretical consideration of the sharing culture and information spaces, which can be regarded as sociocultural phenomena in modern times. Then, it drew sharing culture-based spatial design factors-access, openness and plurality. It analyzed configuration of spaces for sharing information-Cultural Commons (CC), Information Commons(IC) and Learning Commons (LC) - and infrastructure of information spaces, for library cases-five domestic and foreign public libraries-. The findings show that modern library spaces reflect historical needs for the sharing culture and actively serve their roles through spatial infrastructure including contents (programs) and services for sharing knowledge. The study is determined to be valuable as basic data in establishing the infrastructure of information spaces reflecting modern social trends and cultural phenomena, in expecting spatial structures in which knowledge is reproduced and planning spaces of libraries in the future.

The purpose of this article is to comparatively depict the organizational effectiveness of two rail firms based on the cognitive response of employees(group of drivers). To attain this purpose, several aspects of current personnel and organization management system and organizational culture are surveyed through questionaire and analyzed by SPSS. The questionaire includes two parts of items. First, it includes items on personnel-related factors such as evaluation system, job, wage, role, leadership and job satisfaction. Second, it includes items on organizational culture model suggested by Rousseau. The major findings are : 1) In general, the cognitive response of drivers in two firms concerning personnel-related aspects is to a certain degree negative. 2) The cognitive response of drivers in two firms concerning culture-related aspects is also awfully negative. 3) Job satisfaction of drivers in the firm A is highly related to role and leadership factors in terms of personnel-related aspects, on the one hand, and to achievement factor in terms of culture, on the other hand. In case of the firm B, job satisfaction of drivers is highly related to personnel evaluation factor as well as role and leadership factors in terms of personnel-related aspects, on the one hand, and to affiliation, power, and bureaucracy factors in terms of culture, on the other hand.

This study examined the effect of railway traffic controllers' negative perception of organizational culture on their job demand and job satisfaction in relation to the moderating effect of self-efficacy. Results showed that the aggressive/defensive culture based on power and competition, had a positive (+) effect on job demand and job satisfaction. On the other hand, in the conditional process model in which self-efficacy affects the relationship between organizational culture, job demand, and job satisfaction, self-efficacy played a significant role in lowering the level of job demand, and it contributed to the increase of job satisfaction through a mediating effect. This results suggest the needs for lowering the level of job demand by changing the present aggressive/defensive organizational culture into the constructive one. And also, much consideration for maintaining the level of their self-efficacy should be spent.

The biological wastewater treatment system is known to have an important role in reducing the quantify of enteric virus in water environments. To clarify the roles of activated sludge microbes in decreasing the virus infectivity, the behavior of the virus in bacteria, protozoa, and metazoa was examined by pure or mixed culture system using poliovirus type 1(Lsc, 2ab strain). In the bacterial culture systems, the virus infectivity in the liquid phase decreased by a reversible adsorption of the virus to the bacteria or bacterial flocs. On the other hand, in the protozoa and the metazoa culture systems using T. pyriformis and P. erythrophthalma, respectively, with a variety of bacterial strains as prey, the main virus decrease mechanism of reversible adsorption in early stage was changed to irreversible predation, which was not eluted in this study. The virus decrease was more effective in the P. erythrophthalma culture system, which had high predation and floc forming abilities. However, in the mixed culture system of Z. ramigera and P. erythrophthalma, the more rapid reversible adsorption of virus to Z. ramigera flocs preceded the irreversible predation of P. erythrophthalma.

This study has interest in the cultural environment in the local areas. Despite continuous efforts to establish a new law for the culture and arts in the local areas, they failed because of its non-systematic approach to legal system of culture and arts areas. In order to establish a new law of culture and arts development in the local areas, it explores the existing efforts and foreign cases for the legislation, and analyses the legal system in culture and arts. As a conclusion, it suggests recommendations; Firstly, culture and arts should be separated regarding the legislation for cultural development in the local areas. Secondly, the articles which share same or similar meaning in the existing laws should be rectified. Finally, the roles of central government and local government should be identifies regarding public supports for culture and arts in the local areas.

Mycobacterium tuberculosis complex (M. tuberculosis complex) is a causative agent of contagious chronic disease in a wide range of mammalian hosts, mainly cattle, goat, pigs, wildlife, and humans. The definite diagnosis of tuberculosis is made based on culture of M. tuberculosis, but it takes a long time. In the present study, we analyzed whether the detection time of M. tuberculosis could be reduced when cultured in the medium containing the culture-promoting ingredients-107 (CPI-107) using the BacT/Alert 3D system, an automatic culture system. The time to detection (TTD) tended to decrease as the added concentration of CPI-107 increase. In the case of low numbers of M. tuberculosis, it decreased by 21.0% at 1.2 mg/mL of CPI-107 and by 15.9% in the case of high numbers of M. tuberculosis. In the culture using clinically isolated M. tuberculosis strains, the shortening of the culture time by CPI was more evident. In conclusion, the detection time of M. tuberculosis was shortened in the medium added with CPI-107, and this could be used for isolation, culture and drug susceptibility test of M. tuberculosis.

Aircraft accidents are characterized by a low probability of survival compared to other means of transportation, and the main causes appear to be human factors such as violation of regulations and communication. In order to activate the safety management system to prevent such accidents, an important key variable is to recognize the importance of safety culture and actively engage in safety behavior rather than simply emphasizing compliance with regulations to flight crew members. Even if there are well-established regulations, safety culture, The effectiveness varies depending on the safety atmosphere and level of safety behavior. In this study, the correlation between safety culture and safety behavior was verified through a survey of domestic flight crew members' awareness of safety culture. The results showed that fair culture and self-reporting were not activated enough to have a significant impact on safety behavior. We aim to improve the performance of the safety management system by confirming the characteristics of safety culture and safety behavior.

Traditional culture technology of medicinal plants mainly depends on the field culture, which has many problems. With progress of modern culture technology, it has become possible to produce valuable secondary metabolites from medicinal plants. In this paper, we discuss about the pigment and saikosaponin production from too medicinal plants, Carthamus tinctorius and Bupleurum falcatum, through bioreactor culture system. A two-stage bioreactor culture system was established for the production of yellow and red pigments and saikosaponins by cell suspension cultures of Carthamus tinctorius and Bupleurum falcatum. In Carthamus tinctorius, balloon type airlift bioreactors and column type airlift bioreactors were employed for the tell culture and for the pigment production, respectively. The greatest pigment production was obtained on White medium supplemented with 4 mg/L kinetin, high levels of sucrose concentration and photosynthetic photon flux. In Bupleurum falcatum, adventitious roots were cultured in balloon type airlift bioreactors and the root growth was greatest on SH medium containing 5 mg/L IBA and 0.2 mg/L kinetin. HPLC analysis showed that the contents of main active saikosaponins a, c, and d in adventitious roots were almost the same as those in field cultured root.

Perfusion culture was conducted in Celligen perfusion culture system using a self-constructed hybridoma cell and low serum medium. The culture system employed hollow fiber to separate cells from the culture broth. Maximum cell density of $2.1\times10^7$ ce11s/m1, 10 times higher than in batch culture, could be achieved. Concentration of monoclonal antibody (MAb) was 4 times higher and production rate at maximum feed rate was 9 times higher than in batch culture. Glucose concentration was very important for the cell growth and MAb production. When glucose concentration was below 1g/l, i. e. 0.5~0.9g/l, specific MAb production rate decreased but cell concentration still increased. As the glucose concentration goes above 1g/l, specific MAb production rate increased and remained at maximum value at more than 1.5g glucose/l. The maximum value of the specific Mab production rate was similar to that of batch culture.

The purpose of this study is to clarify the perception and educational needs of international college students regarding the culture of college life. A questionnaire was given to international college students who are studying at universities in Korea. The results showed that international college students need to study about the culture of college life and had a perception that it is desirable to learn this through general education classes or freshman subjects after entering university. Also, the culture of college life can be divided into nine categories: bachelor's system; career and employment; university support centers and systems; interpersonal relations; departmental events; housing and living expenses; freshmen's events; exchange activities and programs; and cultural experience activities. International college students showed higher learning needs in order of career and employment; cultural experience activity; and bachelor's system. In addition, the characteristics of the learners showed different educational needs according to year of study and Korean language proficiency. The significance of this study is to specify the items of the culture of college life required for international college students, to measure the validity and reliability of these items, and to categorize the elements of the culture of college life.
