English is an important tool of information literacy in terms of global information sharing environment. This impacts readers advisory services of public libraries in many ways. In order to identify status of English reading programs in public libraries, this paper investigated 50 public librarries' services for non-English speakers in California, which has long history serving readers advisory services to them. As a result, it is suggested that public libraries have to play a key role to help adult users to be competent in English with English reading programs. Public libraries also need to support families to build English reading environment at home to expand reading activities in libraries. In addition, reading habit in mother tongue is also important for English reading ability, so public libraries consider to build a bridge between them to provide effective English reading programs.

Nuclear power has been an attractive energy efficient and to the pressure with the climate change despite of its risks. There are safety, security, and environmental concerns with the nuclear radiation, but the techno-optimism forms the mainstream by experts and the state to be able to control and manage the risks yet occurred. The disastrous Chernobyl and Fukushima nuclear accidents brought about alternative action and thought including renewable energy expansion, efficient energy delivery and use, and enhancing stewardship to environmental carrying capacity. More significant alternative movement is sought by victims of nuclear radiation, technicians, and the general public who realized the pitfalls of expert and state centered policy formation. These laypersons become counter-expertise competent in recognizing local contamination and considering the risks and emotions seriously affecting peoples' everyday lives. They play important roles in the construction and legitimation of alternative knowledge about nuclear power widely realized across regions.

As modern warfare has changed into network centered, the ability to share situational awareness among allies become a core competency for performing operational missions. In an airborne environment, it uses a tactical data link such as Link-16 for shared situational awareness. There exist problems when it shares situational awareness over the existing data link that can not allocate slots dynamically or that can not change the number of a slot to be allocated. In addition, there was a problem that can not share this failure so that failed to improves situation awareness because of finite time slot resources. In this paper, we accommodate dynamic slot allocation and changes of slot allocation with mixed structure of TDMA (time division multiple access) and random access. We propose a technique that can be used when available slots are exhausted, and a load balancing method to prevent slot allocation delay when slot requesting or message sending is concentrated on a single subframe.

Language intervention through cooking activity programs is designed to provide an efficient teaching method and improved educational environment in the field of teaching. This program addresses the effects of this program on the language development of three three-year-old infants (M;2, F;1) in the Center in Seoul. A cooking topic suitable for the age of this group was selected. The language Intervention was conducted for 50 minutes per week for a total of 25 times, and made use of vocabulary, verbs and nouns related to cooking which were evenly distributed. In this study, the Peabody Picture Vocabulary Test-Revised (PPVT-R), receptive language age (RLA) and expressive language age (ELA), and Preschool Receptive-Expressive Language Scale (PRES) were used to analyze the collected data. After the study, the cooking activity was accomplished with normal development outcomes appearing in the ability of vocabulary, receptive language, expressive language, and integrated language. There is now a solid evidence base supporting the efficacy of cooking activity in producing positive outcomes in the language development of language delayed infants. Consequently, cooking can induce their active participation and interest and extend their language abilities through various experiences.

최근 정보기술을 기반으로 하는 원격교육에 대한 관심이 집중되는 것은 무엇보다 교육의 저비용.고효율 구조를 실현할 수 있는 대안교육의 하나이기 때문이다. 그러나 정보기술을 매개로 하는 원격교육의 효과에 대해서는 누구도 장담할 수 없는 입장이다. 정보기술의 활용이 필수적인 원격교육 환경에서 학습자들이 정보기술 자체에 대한 두려움으로 인해 수업에 대한 거부감을 나타낸다. "시작이 곧 그 절반이다" 라는 속담처럼, 원격교？ㄱ의 기본 도구인 정보기술에 대한 첫인상은 교육의 성과에 대해 큰 영향을 미칠 것이다. 정보기수의 수용과 사용에 있어서 개인적인 차이를 설명할 수 있는 중요한 개념중의 하나가 정보기술 자기효용감(IT Self-efficacy) 자신의 정보기술 사용능력에 대한 믿음 또는 자신감이다. 교수자가 정보기술 자기효능감의 중요성을 인식하고 이에 영향을 미치는 변인들을 파악할 수 있다면 학습자의 정보기술 자기효능감을 개발시키고 고무시킬 수 있는 훨씬 나은 교수설계를 할 수 있을것이고 효과적인 수업이 가능할 것이다. 따라서 본 연구에서는 자기 효능감이론(Self-Efficiency Theory)에 근거하여 정보기술 자기효능감이라는 개념을 소개함과 동시에 정보기술을 매개로 이루어지는 원격교육 환경하에서 그 역할을 조명해봄으로써 효과적인 교수설계를 위한 틀을 제시하고자한다.을 제시하고자한다.

Photoperiod (length of light per day) is a major factor in regulating reproductive function in golden hamsters. The information of photoperiod is transmitted to the reproductive endocrine system by melatonin. Thus the effects of melatonin aye investigated in male golden hamsters exposed to photoperiods. Paired testicular weights were markedly reduced in the animals housed in short photoperiod $(SP,\le{12\;hours\;day^{-1})$ and injected with melatonin in the evening, but not in long photoperiod $(LP,\le{12.5}\;hours\;day^{-1})$ and injected with melatonin in the morning. The histological examination of regressed testes showed reduction of tubular lumen diameter including the numbers of cells and Leydig cell number. The mean values of both follicle stimulating hormone (FSH) and luteinizing hormone (LH) were also lowered in the sexually inactive animals than in the sexually active animals. Melatonin receptor was identified by reverse-transcription polymerase chain reaction (RT-PCR) and its expression was examined in various tissues to scrutinize the action site of melatonin. It turned out 309 nucleotides and was definitely expressed in hypothalamus and pituitary including spleen, retina, and epididymis. And gonadotropin releasing hormone (GnRH) gene, which is a key element in regulating reproduction, was identified by RT-PCR but the expression of GnRH was not modified by the treatment of melatonin. Taken together, photoperiod via melatonin indirectly affects reproductive endocrine system, possibly through the release of GnRH, not the synthesis of GnRH.

It is important to consider an equitable allocation framework for domestic GHG emission reduction. First, the study established criteria and indicators for the National Allocation Plan (NAP) based on the principles of cost-efficiency and social-acceptance, and performed a case study of the sectoral effort sharing method, using the effort sharing index. The equity analysis of effort sharing based on sectoral preferences and inter-sectoral equity using a Lorenz Curve are performed. The equitable method is more likely to be suitable than the economic one which considers just reduction potential. Equitable effort sharing reflects a higher level of equity than economic effort sharing. At the same time, the equitable effort sharing method is essential for reflecting equity and establishing criteria for equity because evaluation with the equitable effort sharing method depends in particular on the weight of equity criteria. The result suggests the importance of consideration of equity and the establishment of equity criteria. In conclusion, it is critical to consider not only cost-efficiency but equity in policy decision making in terms of the sectoral effort sharing for national GHG reduction target.

The main purposes of the study were to identify factors affecting health-related quality of life of elderly stroke survivors, and to suggest social work interventions for improving their quality of life. The participants were 328 elderly stroke survivors over 55 years old recruited from 18 long-term care hospitals and 13 nursing care facilities in Chung-Nam Province, Korea. The data was collected through a direct survey method from Dec. 16, 2008 to Jan. 17, 2009. Statistical analysis revealed that the overall health-related quality of life among participants was relatively low, especially in the social relationships domain. As a result of hierarchical multiple regression analysis, depression emerged as the most significant predictor of elderly stroke survivors' health-related quality of life, followed by financial burden in future, activities of daily living, acceptance of disability, comorbidity, and major financial supporter(spouse). Health-related quality of life of elderly stroke survivors in long-term care facilities was affected by a variety of variables from disease-related factors to environmental ones. Particularly psychosocial variables were the most powerful factors to predict HRQOL of elderly stroke survivors. Based on the results, social work implications were discussed in the context of developing clinical strategies to alleviate elderly stroke survivors' health-related quality of life in long-term care facilities. Living with chronic illness and disability is a great challenge to the elderly. Most of all long-term residence in care facilities can cause deterioration of quality of life in old age. From now on, studies on health-related quality of life of elderly with chronic illness and disability should be activated in social work field.

This study was conducted to find out a useful bioremediation technology for heavy metal contaminated soil and water. We isolated strain CPB from heavy metal contaminated soil and evaluated the tolerance level and adsorption capacity of strain CPB to heavy metals (Strain is not determined yet). Strain CPB showed variable tolerance limit to different kinds heavy metal or concentrations of heavy metals. The growth of strain CPB was significantly inhibited by mixed heavy metals (Cd+Cu+Pb+Zn) than that of by single heavy metal. Strain CPB showed high binding capacity with Pb (Pb>Cd>Cu>Zn). In general, strain CPB showed high uptake of heavy metals such as Pb, Cd and Cu. It was observed that the capacity of heavy metal uptake from mixture of heavy metals was reduced in comparison with single heavy metal treatment. But total contents of heavy metal bound with cell in mixed heavy metal showed higher than in single heavy metal treatment. Heavy metal adsorption in cells was affected by several external factors, such as temperature and pH etc.. The optimum temperature and pH of the adsorption of heavy metal into cells were ca. $25{\sim}35^{\circ}C$ and pH ca. $5{\sim}7$, respectively. A large number of the electron dense particles were found mainly on the cell wall and cell membrane fractions, which was determined by transmission electron microscope. Energy dispersive X-ray spectroscopy revealed that the electron dense particles were the heavy metal complexes the substances binding with heavy metals.

21세기를 맞이하는 기업은 세계화와 국제화, 정보의 다양화 및 분산화, 제품수명주기의 단축과 수익률의 감소, 고품질의 제품, 지식산업의 등장, 고객 욕구의 증대 등 다양한 내 ${\cdot}$ 외적 환경변화에 대응해야 하고 경쟁우위를 확보하기 위해 끊임없이 기업의 변화능력을 확보해야 한다. 기업은 제품을 생산하여 판매하는 기업의 시스템 전체가 경쟁력을 갖추어 총체적 우위를 확보하고 고객의 기호와 감성에 호소하는 제품을 만들 수 있도록 다양한 정보를 제공하는 시스템을 필요로 하게 되었다. 즉, 시간과 서비스에 뒤진 고객지원체계는 기업의 성장에 절대적인 마이너스 요인이므로 고객 정보의 효율적 관리, 고객 요구에 대한 신속한 대응, 정기적 고객만족도 조사 등 고객이 원하는 것을 재빠르게 얻어낼 수 있는 고객 친밀형 정보시스템의 확립이 요구되는 것이다. 이를 해결해 줄 수 있는 새로운 경영정보시스템이 바로 WebERP인 것이다. WebERP는 기업의 원활한 자재, 구매활동을 위해 제안된 MRP에서 시작되었으며, 생산관리의 개념을 포함하고 있는 MRPII로 확대되었다가 다시 인사나 회계, 재무 등 조직이나 기업의 전업무영역을 수용하는 종합경영정보시스템으로 발전된 것이다. 현재는 전자상거래와 관련하여 WebERP의 필요성이 부각되었고, 모기업과 협력사간의 구매발주 및 납품관리를 확대시켜 소모성자재(MRO: Maintenance, Repair & Operation) 및 기타 공동구매서비스와 유사업종간의 그룹을 형성하여 ASP(Application Service Provider)의 공동 환경을 이용한 WebERP 환경을 이용한 WebERP활용이 현시점으로 적실히 필요한 것이다. 이는 중소기업들의 공동 협업체제를 도모하여 외세를 대비하는 응집력을 확고히 함으로써 집단체제의 e마켓플레이스 확립과 더불어 국제경쟁을 대비한 방안으로서 집단 공동의 웹환경 인프라가 필요한 것이다. 이러한 배경에서 ASP환경을 이용한 WebERP활용방안과 시스템 구축전략을 경남지역의 기계산업정보화사업단이 추진하는 일반기계, 전기기계, 금속기계, 수송기계, 정밀기계의 5개 업종을 4,877개 기업 대상으로 추진하고 있으며, 그 중 WebERP의 모델로서 2003년도까지 50개 기업을 선정하고, 이는 5개 업종 골고루 선정하여 적용과 표준화 모델로 전개해 나가는 것을 정리한 것이다.
