  • This study was conducted to assess the recognition and consumption of health functional food (HFF) of the college students in the Northern Gyeonggi-do area (Republic of Korea). To accomplish this, a survey was conducted to investigate 360 college students (183 males and 177 females) regarding their general characteristics, as well as the recognition, knowledge, considerations, purchases and consumption of HFF. Most male and female students (68.9% and 61.6%, respectively) were unaware of the HFF certification mark, however, more females(58.8%) were aware of the legal HFF definition compared to males (36.6%). The HFF advertising routes for males and females were 'TV radio' (43.2% and 43.5%, respectively) and 'internet smart phones' (19.7% and 27.1%, respectively). The main factor considered for selection and the most serious problem concerning HFF by males and females were 'effectiveness' (36.1% and 43.6%, respectively) and 'hype (exaggerated advertisement)' (35.0% and 55.9%, respectively). The main purchase route by males and females was 'pharmacy' (35.2% and 27.8%, respectively). The main reason for HFF product purchase by males and females was 'health promotion' (38.8% and 29.4%, respectively) and the main reason for not purchasing an HFF product was 'no health problem'(34.8% and 36.7%, respectively). The percentage of HFF consumption was 46.0% in males and 69.8% in females. The main HFF product consumed by males and females was 'vitamin mineral' (36.9% and 43.5%, respectively). The main reason for HFF consumption by males was 'health promotion' (31.0%) and females was 'recovery from fatigue' (21.8%). The main reason for not consuming HFF by males and females was 'no health problem' (38.4% and 41.5%, respectively). These results suggest the need to provide correct information concerning HFF to college students. Based on these results, greater efforts should be made to provide meaningful information regarding factors affecting purchase and consumption patterns for college students related to the research and development of HFF in the Northern Gyeonggi-do area.

  • The Integration Host factor (IHF) of Escherichia coli is a small, basic protein that is required for a variety of functions including site-specific recombination, transposition, gene regulation, plasmid replication, and DNA packaging. It ,is composed of two subunits that are encoded by the ihfA ($\alpha$-subunit) and ihjB ($\beta$-subunit) genes. IHF binding sites are composed of three elements called the WATCAR, TTG, and poly (dAT) elements. We have characterized IHF binding to the H site of bacteriophage λ. We have isolated suppressors that bind to altered H' sites using a challenge phage selection. Two different suppressors were isolated that changed the adjacent $\alpha$P64 and $\alpha$K65 residues. The suppressors recognized both the wild-type site and a site with a change in the WATCAR element. Three suppressors were isolated at $\beta$-E44. These suppressors bound the wild-type and a mutant site with a T:A to A:T change (H44A) in the middle of the TIR element. Site-directed mutagenesis was used to make several additional changes at $\beta$E44. The wild-type and $\beta$E44D mutant could not bind the wild-type site but were able to bind the H44A mutant site. Other mutants with neutral, polar, or a positive charge at $\beta$E44 were able to repress both the wild-type and H44A sites. Examination of the IHF crystal structure suggests that the ability of the wild-type and $\beta$E44D proteins to discriminate between the T:A and A:T basepairs is due to indirect interactions. The $\beta$-E44 residue does not contact the DNA directly. It imposes binding specificity indirectly by interactions with residues that contact the DNA. Details of the proposed interactions are discussed.

  • Background and objective: This study was conducted to understand urban residents' perception of indoor plants in order to assist in the preparation of guidelines for growing plants indoors. Methods: Questionnaires were distributed to urban residents currently growing plants or with experience of growing plants. The data of 247 respondents were subjected to analysis to assess their level of interest and ability with regard to growing plants, and their recognition of the selection and function of plants. Results: Respondents showed high interest in growing plants at a level of 6.77, but their ability was moderate. This suggests that information regarding plant maintenance should be provided to urban residents. They recognized the function of plants for improving the environment as important, and expected that indoor plants would improve their mood and visual experience. Satisfaction with growing plants was high from an emotional perspective. They recognized that the function of air purification function was important even if the actual performance or effect was not great. This indicates that the function of air purification should be emphasized more. As the result of the IPA, plants should be selected in consideration of morphological characteristics such as leaf, flower and fruit, and continuously managed to maintain their characteristics. Since the performance of pots was less satisfactory compared to their importance, they should be selected so that they harmonize better with plants and are of the appropriate size to fit the space. The type of plants is an important factor in plant selection in order to perform an environmental function, and the flower color and pot size are important in terms of aesthetics and healing. Conclusion: When horticulture information on indoor plants is provided to urban residents, first, it should be provided to satisfy the functions of the plants required by urban residents and in order to promote and maintain the proper growth of plants. Second, various contents that utilize components should be developed to achieve plant function so that resident can determine the function of plants and select the type, quantity, and shape of plants to achieve the desired function.

  • 본 연구는 초등학교 수학 학습 부진 학생들의 진단평가 결과 및 교사와 학생들의 설문 결과를 바탕으로 초등학교 수학 학습 부진의 발생 경향을 분석하는데 목적이 있다. 본 연구 결과, 수학 학습 부진 학생들은 저 중학년에서 고학년으로 올라감에 따라 부진이 점차 누적 및 심화되어 나타나는 경향을 보였다. 이는 수학 학습 부진이 저학년 시기부터 시작되어 나타난 결과임을 의미한다. 또한, 단순히 총점수로만 부진 여부를 판별하는 현재의 방법에만 의존하기 보다는 영역별 점수 및 교사와 학생들의 인식 등을 종합적으로 고려할 필요가 있다. 현재의 방법이 또 다른 학습 부진의 원인이 될 가능성을 인식할 수 있었다. 마지막으로, 수학 학습 부진 학생지도를 담당하는 대다수의 교사들과 학생들은 수학 학습 부진의 원인이 학생들 자신의 내재적 요인에 의해 발생한다고 응답하였으며, 이는 수학 학습 부진 학생에 대한 교육적 처치 방안에 대한 연구를 통해 개선될 수 있음을 의미한다. 따라서 학생들이 초등학교 저학년 때부터 수학에 대해 긍정적이고 성공적인 경험을 하여 학습 결손이 생기지 않도록 지원해주어야 하며, 학생들의 객관적이고 체계적인 자료 분석에 바탕을 둔 지도 방법으로의 개선이 필요하다.

  • For as to world, the concern about the environment problem is enhanced than any other time in the past because of being 21 century. And the environment problem is highlighted as the world-wide issue. The time of the environment problem intimidates the alive of the mankind and presence of an earth over the time. It becomes the essentiality not being selection in the personal living or the economical viewpoint now to prepare for the climatic modification. As to the company management, the green growth period which it excludes the environment management considering an environment, cannot carry on the company the continued management comes. That is, in the change center of the management paradigm, there is the environment management. Nearly, the greenhouse gas which the publication industry is the environmental toxic material like all industries is generated. The greenhouse gas is ejected in the process of running the manufacturing process and print shop of the various kinds material used as the raw material of the book. Particularly, the tree felling for getting the material of the paper is known to reach the direct influence on the global warming. This study does according to an object it considers and organizes the environment parameter based on this kind of fact as to the publication industry. And it is determined as the reference which is used as the basic materials preparing the case that carbon exhaust right transaction(CAP and TRADE) drawing are enforced in all industries and is sustainable the management of the publication industry and reduces the environmental risk among the company many risk management elements and plans and enforces the publication related policy that there is a value. In the printing publication industry, this study tried to inquire into elements discharging the environmental pollutant or the greenhouse gas. Additionally, in the printed publication production process, it tried to inquire into the effort for an environment-friendly and necessity at the printing paper and the printers ink, regarded as the element discharging the greenhouse gas all kinds of the printing materials, operation of the print shop and all kinds of the machines and recycle process, and etc. These considerations make these industrial field employees aware of the significance about a conservation and environmental protection. They try to give a help in the subsequent study producing quantitatively each environmental parameter emission of green house gas. This makes the calculation of the relative $CO_2$ output reproached ultimately possible. Meanwhile, in a sense, many research protects and improving an environment in connection with the contents of research at the printing publication industrial field is in progress. There will be the voluntary human face that it has to protect an environment but this can not do by the outside factor according to all kinds of environment related law and regulation. Anyway, because of acting on company management as the factor of oppression, the increase of this environment-related correspondence cost could know that the research that the environment loading relates with a procurement and development, environment management system introduction, quality control standard, including, normalizing including a material, and etc. through the part of the effort to reduce the cost low was actively in progress. As to the green growth era, as follows, this paper prescribed the subject and alternative of the print publication industry. It is surrounded by the firstly new digital environment and the generation of the subject. And secondly the printing industry is caused by the point of time when the green growth leaves by the topic which is largest in the global industry and it increases. The printing publication industry has to prepare the bridgehead for the environment-friendly green growth as the alternative for this resolution with first. The support blown in each industry becomes the obligation not being selection. Prestek in which the print publishing was exposed to spend many energies and which is known as the practice of the sustainable print publishing insisted that it mentioned importance of the green printing through the white pages in 2008 and a company had to be the green growth comprised through the environment-friendly activity. The core management for the sustainable printing publication industry presented from Presstack white pages is compacted to 4 words that it is a remove, reduce, recover, and recycle. Second, positively the digital printing(POD) system should be utilized. In the worldwide print out market, the digital printing area stops at the level of 10% or so but the change over and growth of the market of an analog-to-digital will increase rapidly in the future. As to the CEO Jeff Hayes of the Infoland, the offset print referred to that it of the traditional method got old and infirm with the minor phase of the new printing application like the customer to be wanted publication and the print of the digital method led the market. In conclusion, print publishers have to grasp well the market flow in the situation where a digitalization cannot be generalized and a support cannot avoid. And it keeps pace with the flow of the digital age and the recognition about the effort for the development and environment problem have to be raised. Particularly, the active green strategy is employed for the active green strategy.

  • Purpose - Over 90% of Domestic logistics industry is small enterprise and they are experiencing growth stagnation due to price-based competition structure rather than constructing logistics service of high added value. In order to get over this situation and pursue the development of logistics industry, strengthening its competitiveness, through inter-enterprise cooperative network build-up, would be a key alternative. Therefore, in this study, an index for measuring inter-enterprise cooperation level of Joint logistics business will be developed as a typical collaborative business model in logistics industry. Moreover, a strengthening competitiveness method suggests a developmental step and a key management index to mature in logistics industry. Research Design, Data, Methodology - This study is an index development research for measuring inter-enterprise cooperation level of logistics industry. Such a level was measured by performing a survey by targeting enterprises that participated in Joint logistics business. The targeting enterprises are typical cooperative models in logistics industry. Measurement items were developed which were based on the presented items in existing research. Question items were composed of selection type questions as answering Yes/No. They measures implementation status of corporate activity and detailed activity items measuring qualitative level. Total samples were based on 116 enterprise samples including 90 logistics enterprises and 26 shippers. In addition, by evaluating the importance for Joint logistics business recognition with personnel working level, the weight of measuring variable was extracted. This study has built an assessment tools (LPCI) on Joint logistics business cooperation level in a situation where there are no previous studies on joint logistics business, this study is meaningful for other studies. Results - As a result of analyzing LPCI presented in this study, the score of logistics enterprise was represented as 59.9 points based on full score of 100 points and that of shippers as 47.2 points and cooperation level among enterprises participated in Joint logistics business was revealed to be very low. In particular, as a result of measuring the importance between logistics enterprise and shippers, the difference by each measurement standard was represented among those enterprises. This difference is considered to be a key factor that cooperative operational conformity between logistics enterprises and shippers is represented to be low. Conclusions - As most joint logistics business, being promoted at present, is sharing facility and information with joint logistics business, it is hard to find such a joint logistics business in reality based on cooperative business model in main cooperation agents. Therefore, competitiveness of logistics industry could be strengthened by promoting joint logistics business based on their mutual cooperation among enterprises. In other words, it is to secure sustainable competitiveness of joint logistics business together with creation of new market by inter-enterprise cooperation based on integration of basic logistics business.
