Information culture is a concept with multiple and sometimes conflicting definitions. Nevertheless at a time when social and cognitive aspects of information and communication systems are recognized as being of similar significance as the technological functionality, the concept of information culture is demonstrating considerable value. This paper explains the concept of information culture and considers its value from two main perspectives: firstly as providing an analytical tool, and secondly as a means of providing practitioners with insight and sensitivity to the organisational contexts of their workplaces.

The totality of language learning comprises three integrated components: linguistic, cultural, and attitudinal (Wilkes, 1983).Positively sensitizing students to cultural phenomena is urgent and crucial. A positive attitude toward L2 culture is a factor in language learning that leads to cross cultural understanding. This research examined, through a survey analysis, how three groups of students (one high school group and two university student groups) viewed the role of their foreign culture (i.e., American and British cultures) in achieving cultural understanding. The focus was upon how EFL learners approach the target language culture as well as their own culture.

Efficient plant regeneration system was established through the culture of rice (Oryza sativa L.) microspores. Microspores released by anther shedding culture developed into proembryos and calluses in B5 medium within two weeks of culture. The optimal hormone and carbon sources were dependent on the genotypes used. Microspore's viability decreased rapidly in culture time, therefore less than 3% of the total microspores were viable at the 9th day when the first microspore division was observed. Of two types of microspores (pollen dimorphism) observed in culture, only the P-grain, larger microspores than normal one was able to divide. Using 4',6-diamidino-2-phenylindole (DAPI) fluorescence staining, it was confirmed that the symmetrical division of uninucleate microspore was the first step leading to continuous microspore development. Microspore-derived proembryos and calluses were regenerated to plants in N6 medium containing 1 mg/L NAA and 5 mg/L kinetin, and 78.3% of the regenerated plants were haploids.

Background: To elucidate the relationship between safety culture maturity and safety performance of a particular company. Methods: To identify the factors that contribute to a safety culture, a survey questionnaire was created based mainly on the studies of $Fern{\acute{a}}ndez-Mu{\tilde{n}}iz$ et al. The survey was randomly distributed to 1000 employees of two oil companies and realized a rate of valid answer of 51%. Minitab 16 software was used and diverse tests, including the descriptive statistical analysis, factor analysis, reliability analysis, mean analysis, and correlation, were used for the analysis of data. Ten factors were extracted using the analysis of factor to represent safety culture and safety performance. Results: The results of this study showed that the managers' commitment, training, incentives, communication, and employee involvement are the priority domains on which it is necessary to stress the effort of improvement, where they had all the descriptive average values lower than 3.0 at the level of Company B. Furthermore, the results also showed that the safety culture influences the safety performance of the company. Therefore, Company A with a good safety culture (the descriptive average values more than 4.0), is more successful than Company B in terms of accident rates. Conclusion: The comparison between the two petrochemical plants of the group Sonatrach confirms these results in which Company A, the managers of which are English and Norwegian, distinguishes itself by the maturity of their safety culture has significantly higher evaluations than the company B, who is constituted of Algerian staff, in terms of safety management practices and safety performance.

To investigate clonal variations of recombinant Chinese hamster ovary(rCHO) clones in response to culture pH and temperature, serum-free suspension cultures of two antibody-producing CHO clones(clones A and B), which were isolated from the same parental clone by the limiting dilution method, were performed in a bioreactor at pH values in the range of 6.8-7.6, and two different temperatures, $33^{\circ}C\;and\;37^{\circ}C$. In regard to cell growth, clone A and clone B displayed similar responses to temperature, although their degree of response differed. In contrast, clones A and B displayed different responses to temperature in regard to antibody production. In the case of clone A, no significant increase in maximum antibody concentration was achieved by lowering the culture temperature. The maximum antibody concentration obtained at $33^{\circ}C$(pH 7.4) and $37^{\circ}C$(pH 7.0) were $82.0{\pm}2.6$ and $73.2{\pm}4.1{\mu}g/ml$, respectively. On the other hand, in the case of clone B, an approximately 2.5-fold increase in maximum antibody concentration was achieved by lowering the culture temperature. The enhanced maximum antibody concentration of clone B at $33^{\circ}C$($132.6{\pm}14.9{\mu}g/ml$ at pH 7.2) was due to not only enhanced specific antibody productivity but also to prolonged culture longevity. At $33^{\circ}C$, the culture longevity of clone A also improved, but not as much as that of clone B. Taken together, CHO clones derived from the same parental clone displayed quite different responses to culture temperature and pH with regards antibody production, suggesting that environmental parameters such as temperature and pH should be optimized for each CHO clone.

The differential enhanced degradation of cis- and trans-1,3-D was observed in the previous two studies performed by Ou et al. (1995) and especially Chung et al. (1999). This study was initiated to investigate the involvement of microorganisms in the differential enhanced degradation of the chemicals. As expected, microorganisms were responsible for the enhanced degradation of the chemicals. A mixed bacterial culture capable of degrading 1,3-D was isolated from an enhanced soil sample collected from a site treated with 1,3-D. Similar to the enhanced soil, the mixed culture degraded trans-1,3-D faster than cis-1,3-D. This mixed culture could not utilize cis- and trans-1,3-D as a sole source of carbon for growth. Rather, a variety of second substrates were evaluated to stimulate the differential enhanced degradation of the two isomers. As a result, the mixed culture degraded cis- and trans-1,3-D only in the presence of a suitable second substrate. Second substrates that had the capacity to stimulate the degradation included soil leachate, tryptone, tryptophan, and alanine. Other substrates tested, including soil extract, glucose, yeast extract, and indole (ailed to stimulate the degradation of the two isomers. Therefore, it appeared that the degradation of cis- and trans-1,3-D was a cometabolic process. The mixed culture was composed of four morphologically distinctive bacterial colonies.

The purpose of this study was to compare dietary culture consciousness of rural and urban housewives through a nationwide survey. Interviewers interviewed 500 housewives(250 in rural and 250 in urban) using closed-ended questions. The dietary culture consciousness was divided into two parts of traditional aspect (dietary habit and ritual diet) and desirable aspect (food choice and nutrition knowledge). Each domain consisted of six items. Results of the study are summarized as fellows : 1) As a whole, dietary culture consciousness of rural housewives was more traditional than that of urban housewives in traditional aspect, and there was no difference of consciousness between rural and urban housewives in desirable aspect. 2) There was significant difference at 1% level between two groups in traditional aspect and there was no difference in desirable aspect. 3) By the analysis of each item, there was significant difference between two groups in 14 items. Especially, the item of westernized breakfast pattern was more acceptable in urban housewives than in rural. 4) In relationship between socio-demographic characteristics of housewives and dietary consciousness of them, age, educational level and religion of housewife were significant in traditional aspect, and so were educational level and job experience of housewives in desirable aspect. Dietary consciousness of rural housewives' was influenced by job experience (in traditional aspect) and age of housewives and level of living (in desirable aspect) In the case of urban housewives, level of living was significant in traditional aspect.

Both the total quality management (TQM) and learning organization (LO) appear to be promising approaches for organizational transformation towards a more effective, efficient, and responsive organization in the past. The evolutionary development and theory supports for these two fields are distinct but they appear to have more in common than they have in distinctiveness. However, there is little synergy developed between these two fields both in academic research and industrial applications. It is possibly due to the fact that both the academia and industry are taking a limiting polarized view of TQM and LO and hence not getting the benefits of linking the two. This paper tries to establish a link between the organizational learning capability and the quality culture for TQM implementation based on a case study on the largest vocational education institution, the Vocational Training Council, of Hong Kong. The study reveals that there is a strong positive correlation between organizational learning capability and quality culture. The exploratory explanations for the links between the organizational learning capability constructs and the quality culture constructs are also discussed in this paper. The findings of the study support other literatures that TQM should be embedded in LO and serves as an enabler for organizational learning (OL) in transforming and creating organizations which continuously expand their abilities to change and shape their future.

이 연구에서는 로티퍼 B. rotundiformis의 대량 배양조에서 흔히 혼재가 관찰되는 코페포다 T japonicus가 배양을 목적으로 하고 있는 로티퍼 B. rotundiformis의 증식에 어떠한 영향을 미치는지 알아보았다. 실험에 사용한 로티퍼와 코페포다는 로티퍼의 대량 배양조에서 순수 분리 후 단일종 배양하던 것이다. 배앙 조건은 현장의 배양환경과 되도록 일치하도록 하였으며, 먹이는 $7{\times}10^5\;cells/ml$의 N. oculata를 급이하였다. B. rotundiformis의 배양조에 혼재된 T. japonicus는 C. rotundiformis를 단독 배양한 경우에 비하여 증식이 크게 억제되었고, 실험 종료일까지도 그 증식은 정체되는 양상을 보였다. 그러나, T. japonicus의 증식은 T. japonirus를 단독 배양한 경우에 비교하여 B. rotundiformis와 혼합 배양하여도 그 증식에는 큰 차이가 없었다. 또한, B. rotundiformis와 T japonicu의 혼합 배양에서 두 종간의 피포식 관계나 먹이 경쟁 관계와 같은 직접적인 상호 작용은 관찰할 수 없었다. 이 연구의 결과, 로티퍼 B. rotundiformis의 대량 배양조에서 혼재 생물로서 자주 관찰되는 코페포다 T. japonicus는 B. rotundiformis의 증식 저해요인으로서 작용하고 있음을 알 수 있었다.
