For the learners of English as a foreign language, oral repetition of model sentences is an e essential practice to improve their listening and speaking abilities of English. Skill training of both speech perception and production is involved in this practice. This paper reports on an observation of production e$\pi$ors in such practice made by Japanese college students in my class. The teaching material used is intended for acquainting the learners with basic English rhythm and intonation p patterns. The students were required to repeat each sentence in a series of conversations after a model reading. Although the vocabulary and expressions were rather limited, I monitored different kinds of errors in their repetition. Putting aside intonation, their difficulties are classified into five types; 1. Omission of words or morphemes, 2. Addition of unnecessary words or morphemes, 3. Replacement of words, 4. Japanization of English sounds, 5. Wrong rhythm caused by improper stress assignment. Accurate listening, especially to weakly stressed syllables and to assimilated sounds, as has often been pointed out, is the most difficult part in perception for them. Japanese sound system interferes in production of English sounds. More often than not their knowledge of grammar or the context does not work at all to guess the words they are hearing

The use of a practice perspective in the analysis of information literacy represents a shift in attention towards the enactment of information literacy as a social practice, and away from the information skills approach that has dominated information literacy research and education. The sociocultural perspective that underpins a practice-oriented approach highlights the role of practice and co-participation of the community in shaping the production, reproduction and circulation of knowledge, including knowledge about the appropriateness of information skills in relation to the context in which the skills are practised. This emerging view contrasts with the conventional approach to information literacy that has focused on the information skills of individuals as something that can be learned and transferred independently of context. This paper explores two questions: what is information literacy and, how does it happen? It then goes on to identify the implications of this approach for librarians and researchers.

The space has been interpreted from various perspectives, such as hierarchical, cultural, economic, political factors, etc. So we can see the space as a social existence. Space is now being formed through the dialectical relations of these elements. From this point of view, this study started to research the spatial practice of morden people through the case in the early 20th century film. With the discourse of Henri Lefebvre and David Harvey, and Michel de Certeau's theory, this research tried to find the mechanisms of spatial practice. Also Benjamin is a philosopher who intervenes the relationship between modernity and cultural production and his way of reading cultural phenomena seems to serve as the useful methodology of cultural studies. Modern people were individual unawared of the era, awakened to the ego. They were wandering the room and the street, private and public places. They were city dwellers walking around, collecting goods, and living of everyday life. Spatial practice is a fixed activity and have continuity. spatial practice appeared in the early 20th century film is at the intersection of social practices and the practice of everyday life. Social practices are a fixed practice and continuous practice. The practices of everyday life are nomadic practice and amusable practice. Modern people accommodate and adapt to a given space of the city through fixed practice. They realizes the access and the distance from spaces through continuous practice. They select and approved the spaces through nomadic practice. And they possess exclusively and utilize the spaces through amusable practice. Through These research spatial practices, it could easily found similarities and differences between modern space on the early 20th century and contemporary space of 21st century. True modern is not the past but the present.

Rapidly obtaining the coverage characteristics of leaching solution in In-situ Leaching Area of Sandstone Uranium Mines is a necessary condition for optimizing well locations reasonably. In the presented study, the improved algorithm of the Fast Marching Method (FMM) was studied for rapidly solving coverage characteristics to replace the groundwater numerical simulator. First, the effectiveness of the FMM was verified by simulating diffusion characteristics of the leaching solution in In-situ Leaching Area. Second, based on the radial flow pressure equation and the interaction mechanism of the front diffusion of production and injection well flow field, an improved FMM which is suitable for In-situ Leaching Mining, was developed to achieve the co-simulation of production and injection well. Finally, the improved algorithm was applied to engineering practice to guide the design and production. The results show that the improved algorithm can efficiently solve the coverage characteristics of leaching solution, which is consistent with those obtained from traditional numerical simulators. In engineering practice, the improved FMM can be used to rapidly analyze the leaching process, delineate Leaching Blind Spots, and evaluate the rationality of well pattern layout. Furthermore, it can help to achieve iterative optimization and rapid decision-making of production and injection well locations under largescale mining area models.

Cultural practices for adzuki bean and the distribution of weed species in the south-west regions of Korea were surveyed to provide information on effective weed management. Approximately 27.5% of the farm households were growing adzuki bean in an area larger than 1 ha while the rest grew the crop in an area smaller than 1 ha. Of all adzuki bean growers, 17.1% seeded in early June, 8.6% in mid June, 34.3% in late June, 17.1% in early July, 20.0% in mid July, and 2.9% in late July. The average planting distance was $71.0{\times}29.5cm$. From the 40 surveys in adzuki bean fields, 35 weed species in 17 families were identified. According to the occurrence frequency, the dominant weed species were Digitaria sanguinalis, Acalypha australis, Cyperus amuricus, Echinochloa crus-galli, and Amaranthus nangostanus in decreasing order of dominance. However, based on dry weight, Chenopodium album (34.4%) was the most dominant followed by Acalypha australis (21.9%), Amaranthus nangostanus (19.1%), Digitaria sanguinalis (7.5%), and Portulaca oleracea (6.1%). The exotic weeds found in the field of adzuki were Ipomoea hederacea, Abutilon avicennae, and Celosia argentea. The plant heights of I. hederacea, A. avicennae, and C. argentea were 259 cm, 98 cm, and 76 cm, respectively, while the fresh weights were 850 g, 66 g, and 101 g, respectively. Integrated weed management systems utilizing mechanical, chemical, and biological control techniques need to be developed for effective weed management in adzuki bean production.

Manfredo Tafuri's Ideological criticism in architecture has opened a new horizon to interpreting architecture in modern capitalist architecture for it views architecture not just as a style or formal invention, but in terms of socio-economical process. It offered a comprehensive understanding of a chaotic situation of contemporary architecture and historical meaning modern architectural movements in relation with capitalistic development. However, it has been criticized as architectural pessimism which does not allow any possibility for progressive architectural practice. It was also criticized of epistemological problem of how one could be outside ideology without assuming true consciousness against false consciousness of ideology. Tafuri solves this problem by assuming Althusserian activist concept of knowledge and suggest the concept of labor of writing history of critical historians, instead of a design for utopian society, as a possible critical architectural practice. However, I argue that ultimately ideological criticism does not deny architectural practice itself, nor researches on formal characteristics of architecture. The problem lies rather in the architectural Intellectuals' attachment to the traditional concept of architect as a form giver to the society. By rejecting this myth and broadening the concept of architectural practice from design to production, we can find that Ideological problem is not architectural pessimism, but rather it opens up a new way of approaching to the problem of architectural practice in modern capitalist society.

In Korea there is still no basic standard for organic agriculture and organic farmers in Korea do not follow the minimum requirements of IFOAM basic standard Most of them just practice the organic agriculture applying organic fertilizer, commercial seed without legume, rotation and green manure. But they believe this system is a absolutely environmental friendly agricultural system and it produce a safe agricultural product since they are not aware of the basic standard of organic agriculture at all. The overuse of organic fertilizer by some organic farmer have caused some severe problems risk for nitrate and phosphate leaching. In soil profile showed the potential risk for nitrate and phosphate leaching. In the paper, it is discussed on the environmental friendly function and the safe vegetable production by european organic agriculture which keeps the internationally recognized basic standards of organic agriculture. Therefore it is strongly recommended that korean organic farmer have to follow the IFOAM it is strongly in order to practice the environmental agriculture and produce the safe food. And it is also necessary to introduce to Korea the basic standard of organic agriculture which coincides with IFOAM's and Codex of FAO/WHO immediately if they really want to practice an organic agriculture in the country.

The purpose of this study was: 1) to investigate whether Korean dietitians are engaged in Foodservice Systems Management (FSM) competencies in their current jobs, and 2) to identify the relationship between types of dietetic practice areas and Korean dietitians' usage of FSM competencies. Fifteen FSM competencies were widely used, 17 were somewhat used, 13 were seldom used and the remaining two competencies were little or not used by the dietitians. The most used competency was related to menu planning (98%). Whereas, the least used competency was related to marketing skills (17%). As a whole, the categories of 'technical and communication skills' (78%) and 'production and distribution management' (77%) were more widely used than other FSM categories. Of 47 competencies, 34 competencies were found to be significantly associated with the type of practice area. Considering the findings, the type of dietetic practice area was a strong factor of Korean dietitians' usages of FSM competencies. Of 34 competencies associated with the type of dietetic practice area, 25 FSM competencies were more likely to be used by the dietitians from health care facilities.
