Although people seriously worry that "digital paradox" is a "quiet crisis" to our society as a whole and threatens our future generation, we need to reconsider how we utilize digital media for effective learning as we understand its characteristics and compare the differences among all formats of media that used for learning. The purpose of this study is to suggest and analyze school library media programs as Learning Commons by applying the relevant theories on information, learning, learning with media, and meaningful learning. The study assumes the importance of the school library media programs that manage rich Information in various formats in an educational system. The study provides theoretical grounds and insights to practitioners and researchers in the relevant field as they face the challenges in putting an emphasis of today's school library media programs for student learning in digital age.

'혹한의 동토에는 봄은 오는가' 올 한해 독자 곁으로 찾아갈 책의 운명을 생각하면 가장 먼저 떠오르는 질문이다. 아직도 그 파괴력이 고갈되지 않은 IMF의 위기는 출판인들의 머리에서 떠나지 않는 망령이다. 하지만 이제 출판계는 내성의 시간을 지나 조용히 전열을 가다듬고 있다. 각 출판사들의 기획안을 살펴보면 해동의 기미가 뚜렷이 느껴진다. 우선 몇몇 출판사의 대형 기획물이 출판시장에 모닥불을 피울 것으로 보인다. 한국의 전통문화에 대한 탐구가 심화되고 인문학에서 정신분석학의 활약이 눈부실 전망이다. 대중문학이 여전히 득세할 것이지만 순수문학계도 중견작가들의 저력이 돋보일 것이다. 새로운 천년의 갈림길에 선 한국사회에서 소장파 지식인들의 준엄한 반성과 성찰이 우리 사회에 날카로운 메스를 가한다.

새로운 자원전쟁이후 식량무기야 말로 석유무기에 버금가는 무기로 돼 버렸다. 세계곳곳에서는 기아에 허덕이는 인구와 아사자들의 발생이 매스컴을 통해, 연일보도 되고 있다. 새삼$\ulcorner$말사스$\lrcorner$의 인구론을 비웃으며 소비가 미덕이라고 부르짓던 인간의 콧대가 무색해질 정도로 인간은 식량 위기의 심각성을 실감하고 있다. 우리도 매년 7$\~$8억불의 외화를 소비하면서 식량을 도입하여야만 하는 어려운 실정에 있다. 이러한 식량부족은 필연적으로 축산업에 문제점을 제기해주고 있다. 인간이 당장공복을 채울식량도 부족한데 이것을 가축에 먹여 단백질을 생산하여야만 할까? 우리나라 사료자원도 도입곡류의 의존도를 줄이려고 장기 축산진흥 계획을 수정한다. 새로운 축산정책에서 외곡 의존도가 높은 닭, 돼지를 감소시키겠다고 말하고 있다. 이러한 정책이 과연 바람직한 것인가?

Some of ecological factors and the early life history of endangered freshwater fish, Pseusobagrus brevicorpus, were investigated to proliferate artificially and to restore the population by release seedlings. The density of population in restricted area by small scale dam was 1.25 ind. $m^{-2}$, and the low capacity for reproduction having 200$\sim$250 eggs ind$^{-1}$. were thought to be a reason of this endangered situation. From the result of induction of natural spawning in aquarium after hormone injection it was considered that the spawning substrate would be aquatic plants with slender branches. The hatching was observed after 50 hrs after fertilization and the larvae showed aggressive behavior. Yolk was almost absorbed 3 days after hatching, and the larvae shaped tad-pole grew up to fry after 30 days. We discussed on the strategies for conservation of this species according to those results from investigation on ecology and early life history.

The purpose of this article is to understand the present situation of energy maritime logistics and to suggest a safe way for maritime transportation. In addition, this study is going to assess the risk of maritime transport of energy and propose alternatives in terms of strategy and policy. We examine the security of the Strait of Hormuz, near the east coast of Somalia, the Gulf of Aden and the Strait of Malacca where the Korean tankers pass through and discuss countermeasures responding to a variety of dangerous situations. This article also provides plans for stable supply of energy in case of Korea peninsula crisis and emphasizes the need of establishing cooperation with neighbor countries.

Environmental issues resulting from climate change and energy crises have become global issues, and cycling has gained greater popularity for sustainable transportation. Though many cities are trying to build bicycle roads, it is not easy to implement bicycle roads because there is little available space for bicycle facilities. Therefore, road diets have become more popular in Korea. However, there has been no intensive research to date of their impacts. The purpose of this research is to evaluate the effects of road diets and construction of bike lanes. Every benefit, including energy benefit, environmental benefit, and health benefit is considered, while only time savings benefit has been considered in previous studies. The benefit analysis for the Seoul metropolitan area as a case study shows that road diets have a (1) time saving benefit for only five percent of the mode share and (2) enough total benefit even if bicycle mode share is less than two percent.

Participants can use the allowances and offsets for implementing the compliance in the Emissions Trading Scheme(ETS). There are alternative commodities which are different prices it gives the opportunities to reduce the compliance costs and get the arbitrage. This study analyzes the price driver of spread which is the difference between EUA and sCER using AR-GARCH model, EUA and CER during the Phase 2 in EU ETS. The results show that there are common elements which impacts the EUA and sCER and also different elements between them. EUA and sCER get the effects from energy price and economic criteria such as coal price and financial crisis as common elements. However them get the effects from electric price, policy criteria such as restricted CERs and difference price between EUA and ERU price as different elements. The results shows that spread will be widen if energy price increase, especially oil and electric price give more impacts the spreads. This study has the means that it explains the reason why the spreads will broaden sharply in 2012. And it also suggests the price driver of spread during the whole period of Phase 2. In addition, this study shows that political aspects maybe become the main criteria of price change with structural elements shch as energy price in Korea ETS which starts in 2015.

In the Natural Monument (No. 432) Jeju Sanghyo-dong Cymbidium kanran Habitat (39 ha), flora, vegetation diversity, stand structure, mirco-climate, canopy openness, light environment and soil temperature and moisture were quantified from Oct. 2013 to Feb. 2014. Compare to Seogwipo-si, daily mean temperature ($5.7^{\circ}C$) and moisture (75.8%) in study area were lower at $3.3^{\circ}C$ and 15%, respectively. Mean soil temperature and moisture were $16.5^{\circ}C$ and 37.3%, respectively, and mean litter layer depth (n = 81) was 4.3 cm. Mean canopy openness and light availability at forest floor were 15.5% and $8.5mol{\cdot}m^{-2}{\cdot}day^{-1}$, respectively. Total of 22 species including vascular and bryophyte plants and 6 vegetation group were observed. Castanopsis siebildii was dominant species in study area, and density and basal area were 1,777 stem/ha and $90.3m^2/ha$.

The endemic Korean stumpy bullhead Pseudobagrus brevicorpus is a first-grade endangered wild fish as designated by the Ministry of Environment of Korea. As part of its restoration and proliferation effort, a histological study of this fish was carried out to investigate sex differentiation and gonadal development based on F1 generation individuals obtained by artificial breeding. On days 4~5 after hatching, a pair of genital ridges including clusters of primordial germ cells was observed between the gut and the mesonephric duct. On days 20 after hatching, the ovary began to initially differentiate and contained early oocytes with chromatin-nucleolus and peri-nucleolus stages on days 30~40 after hatching. As yolk material accumulated after day 80 from hatching, the oocytes grew increasingly large and were surrounded by a distinct follicular layer. On days 306 after hatching, the oocytes grew toward a mature ovum. In the males, the testis was distinguished by emergence of spermatogonium cells on 25 days after hatching, and day 40 after hatching it contained a small number of seminal lobes forming cysts. From 173 days after hatching, the testis consisted of numerous enlarged seminal lobes including spermatocytes and spermatids. Over 14 months after hatching, some seminal lumens were filled with spermatozoa.
