The aim of this study is to explore key strategy areas for academic library development planning in Korea. This study started with components of an academic library development plan that were identified in a literature review; those components included among others the major roles, functions, resources, and teaching and research support services of academic libraries. Upon interviewing library staff from 14 academic libraries, this study initially categorized those components into 4 overarching strategy areas and further subdivided them into 12 key components and 24 sub-components. That initial categorization was then reviewed by 6 scholars and practitioners, applying the analytic hierarchy process (AHP), by which this study analyzed the level of importance and priority of the strategy areas and various components. Based on the results, this study ultimately outlines 11 key components and 23 sub-components under the 4 strategy areas for academic libraries in Korea to take into consideration in their development planning.

In the cost management of public construction projects, it is an important issue to develop an adequate cost data for estimating the predetermined amount by various methods. For a long time, a standard of estimation in korea is used as a basis for estimating the predetermined amount of public construction. However, they did not have a reasonable cost data based on a labor and equipment productivity analysis. For this reason, it is difficult to make a reasonable and efficient estimation of the costs, and this situation presents an urgent need for more accurate cost data to use in an early phase. This study analyzed the productivity of form work by the CYCLONE model, and presented the model on the number of optimal labor through sensitivity analysis. This CYCLONE model can be useful in analyzing productivity on the various sizes of form. Also, the regression model to estimate the daily output can be used in predicting the amount of labor. Considering the work duration in the regression model is expected to make the daily output estimation much more accurate.

KIGAM (Korea Institute of Geoscience and Mineral Resources) and MRAM (Mineral Resources Authority of Mongolia) performed joint survey on Bayan-Onjuul W-Mo mineralized area. Following the survey, we carried out magnetic survey. W-Mo occurrences are located with keeping a certain distance from the northern boundary of granite which has higher magnetic susceptibility values. Also, the 3D imaging results of magnetic inversion show that granite bodies are extended to the W-Mo occurrence areas from the deep main body with decreasing of susceptibility. The results of magnetic data analysis are well matched with the general characteristics of ore solution involved with W mineralization. The further study about the hidden ore deposits which have similar spatial relationship between granite and known WMo occurrences are necessary to improve the economic feasibility.

With explosion of wireless traffic it is required to further investigate the technologies on acquiring available spectrum resources and on sharing frequency with existing users. In 3GPP, it is started to study on feasibility and functional requirement of LTE standard in order to extend cellular services offered on only licensed band to 5 GHz unlicensed band. Operating scenario on LTE in unlicensed band is focused on carrier aggregation with licensed band, and the coexistence with Wi-Fi services in 5 GHz band is concerned as a major requirement. For a single global solution framework for licensed assisted access to unlicensed spectrum, listen-before-talk(LBT) mechanism of European regulation for fair access to channel under the coexistence environments is currently examined in 3GPP. In this paper, we evaluate two types of LBT, frame based equipment and load based equipment, with considering LTE carrier aggregation feature and performances of file transferred time and throughput.

Due to the development of spectrum use technology and various services based on radio spectrum, the scarcity of spectrum has been heightened. In this circumstances both the efficiency and fairness of spectrum use need to be raised. Open spectrum access can be a useful approach for both goal. For the open spectrum access the legal institution needs to be reformed to enable it. From the starting point of spectrum use till the end of spectrum use there can be various issues of rights and obligations. So the legal institution for various legal status of spectrum use and establishment and continuous management of DB and fast and respectable dispute resolution mechanism is required.

The growth of food industry has not increased the demand for domestically produced agricultural products as raw materials. This is because the prices of domestic agricultural products are expensive relative to the imported ones and domestic products are hard to be supplied consistently. Thus the connection between domestic agriculture and food industry must begin with the investigation of appropriate items that have potentials to be used as raw materials for food industry. There have been many policies that support regional agriculture such as the policy that fosters regional cluster for agriculture. These policies can contribute to instigate the connection between agriculture and food industry. The infra prepared by the supporting policies and the facilities that food companies are operating can be used together for both agriculture and food industry. The complementary utilizations of the infra and facilities may encourage the connection between agriculture and food industry.

To estimate marine primary production, satellite data are essential for providing much better spatial and temporal resolutions. However, primary production estimation for turbid coastal water such as the Yellow Sea still needs much improvement. Here we evaluate currently available methods of primary production estimation in the Yellow Sea. We focus on comparison of eight combinations from four chlorophyll-a algorithms and two primary production algorithms of the Yellow Sea. Estimated primary production by the eight combinations ranged from 96.5 to $610.2\;gC\;m^{-2}\;yr^{-1}$ in the central region of the Yellow Sea. The new chlorophyll algorithms (presently under development by Korea, China, and Japan scientists) are expected to improve the retrieval of chlorophyll-a in turbid regions compared to the standard algorithm but there are certain unresolved problems. The new algorithm for primary production (which uses adjusted physiological parameters with in-situ data) also needs further improvement.

The effect of bisphenol S (BPS) on the viability and production of reactive oxygen species (ROS) was studied in boar sperm and ovarian granulosa cells. Boar semen was incubated in Beltsville thawing solution with either 0 or $5{\mu}M$ BPS for 3 and 6 h. The viability of sperm was analyzed by SYBR14/PI doubling staining, and production of ROS was detected. Ovarian granulosa cells were also treated with BPS for 24, 48, and 72 h. Then, cell viability (0, 5, 10, and $20{\mu}M$) and ROS production (only 0 and $5{\mu}M$ BPS) were assessed. The results showed that, BPS decreased sperm viability at 3 and 6 h, and that BPS increased ROS production (p<0.05). Also, BPS reduced the viability of ovarian granulosa cells (p<0.05), and stimulated ROS production (p<0.05). These results suggest that BPS damages sperm activation and ovarian granulosa cells in the reproductive system.
