  • Alternative cropping systems would be one of climate change adaptation options. Suitable areas for a crop could be identified using a climate suitability model. The EcoCrop model has been used to assess climate suitability of crops using monthly climate surfaces, e.g., the digital climate map at high spatial resolution. Still, a high-performance computing approach would be needed for assessment of climate suitability to take into account a complex terrain in Korea, which requires considerably large climate data sets. The objectives of this study were to implement a script for R, which is an open source statistics analysis platform, in order to use the EcoCrop model under a parallel computing environment and to assess climate suitability of maize using digital climate maps at high spatial resolution, e.g., 1 km. The total running time reduced as the number of CPU (Central Processing Unit) core increased although the speedup with increasing number of CPU cores was not linear. For example, the wall clock time for assessing climate suitability index at 1 km spatial resolution reduced by 90% with 16 CPU cores. However, it took about 1.5 time to compute climate suitability index compared with a theoretical time for the given number of CPU. Implementation of climate suitability assessment system based on the MPI (Message Passing Interface) would allow support for the digital climate map at ultra-high spatial resolution, e.g., 30m, which would help site-specific design of cropping system for climate change adaptation.

  • The purpose of this study is to analyze status of information service and to suggest its activation strategies after establishing its category in the school library. As a result of establishing scope and contents of information service, materials of information offering and guide are converged on reading education and information literacy curriculum integrated subjects. But the arrival rate of information service is very low like 48.2% under the 2012 Korean Libraries' Management Evaluation. It is especially poor to raise self resilience and school participation of students with information service involved in the affective domain such as readers' advisory service and bibliotherapy. In order to activate its information service, there is an urgent need for systems improvement in placement of the teacher librarian. It is also necessary to reinforce the status of information literacy instruction under the nation-level curriculum and continuous base expansion as a core information service of the school library. Service development for readers' advisory service and bibliotherapy is also needed to contribute to solving problem and stress situation of the student. The school library has to make an effort to connect its information service with local communities for the school community.

  • A sensor network is composed of a large number of tiny devices, scattered and deployed in a specified regions. Each sensing device has processing and wireless communication capabilities, which enable it to gather information from the sensing area and to transfer report messages to a base station. The energy-efficient routing paths are established when the base station requests a query, since each node has several characteristics such as low-power, constrained energy, and limited capacity. The established paths are recovered while minimizing the total transmit energy and maximizing the network lifetime when the paths are broken. In this paper, we propose a routing algorithm that each sensor node reports its adjacent link information to the sink node when a sink node broadcasts a query. The sink node manages the total topology and establishes routing paths. This algorithm has a benefit to find an alternative path by reducing the negotiating messages for establishing paths when the established paths are broken. To reduce the overhead of collection information, each node has a link information before reporting to the sink. Because the node recognizes which nodes are adjacent. The proposed algorithm reduces the number of required messages, because sensor nodes receive and report routing messages for establishment at the beginning of configuring routing paths, since each node keeps topology information to establish a routing path, which is useful to report sensing tasks in monitoring environments.

  • Eutrophication and shortage of phosphate ore raise the necessity of phosphate removal and recovery from wastewater treatment plants. Especially, a sludge treatment system containing highly concentrated phosphate should be targeted for phosphate removal and recovery. This study thus aimed to evaluate the capability of the struvite crystallization process for phosphate removal and recovery from a sludge treatment system of a wastewater treatment plant. Analysis on phosphate concentrations and masses in the sludge treatment system revealed that digested sludge and centrate have phosphate concentrations and masses, high enough to adopt the struvite crystallization process. Chemical equilibrium modeling indicated that the struvite crystallization reaction substantially occurred with pH higher than 8 and $Mg^{2+}$ concentration 1.2 times higher than its theoretical requirement. A series of batch tests with digested sludge and centrate indicated that the phosphate removal reaction by struvite crystallization followed a first-order kinetics and reached over 80% removal efficiency at equilibrium. Aeration in the batch tests was found to purge $CO_2$ in sludge or centrate and increase pH up to 8.7, without adding NaOH. Thus, we concluded that the struvite crystallization process could be an efficient and economical process for phosphate removal and recovery from a wastewater treatment plant.

  • Second, the necessity of adopting subject divisional plan is to secure enough subject librarians and large space These necessities must be fulfilled prior to adopting the subject divisional plan. Third subject divisional plan model for efficient reference service of university library is 'wide-area subject divisional plan model'. 1) In the case of central library, the space model of wide-area subject divisional plan is programmed as undergraduate library for the undergraduate students. And each subject libraries is operated as research library for the professors and graduate students. 2) In central library, the collection model of wide-area subject divisional plan is practiced as offering reference and general education centered data for undergraduate students 'study. And each subject libraries is furnished with research papers, recent journals, and various major-related data. 3) The human resource model of wide-area subject divisional plan is applicated by arranging appropriate librarians at the right place. In the case of central library, the reference librarians and librarians who educate the users and take charge of function are set in to help undergraduate students with their study. Subject library needs to secure subject librarians, librarians who take charge of function, and graduate students who are related to the subject as student assistant. Then it is possible to discriminate reference service by subjects and users.

  • The neccessity of hillside land reclamation for food production in Korea is no matter of question. Accordingly, the Government has launched some large scale hillside land reclamation projects. From the past experiences followings are pointed out as to the rational hillside land reclamation engineering methodologies. 1. It is observed that due to the shortages in labor and high wage, the machanization in hillside land reclamation will be an urgent subject. 2. There are several engineering methods for the reclamation of hillside lands; contour terracing, improved contour terracing, bench terracing and sloping bench terracing. 3. Selection of suitable methods will demand the considerations on the topography, particularly degree of slope, and the land use after reclamation. For ordinary crops cultivation, slope should be low and contour terracing is to be recommended, to enable the introduction of machines. In case of grass land development, after smoothing the land surface, improved contour terracing might be selected. And for the orchard development, sloping bench terracing with the construction of roads between the terrace will be suitable.

  • The WBAN technology means a short distance wireless network which provides each device interactive communication by connecting devices inside and outside of body. Standardization on the physical layer, data link layer, network layer and application layer is in progress by IEEE 802.15.6 TG BAN. Wireless body area network is usually configured in energy efficient using sensor and zigbee device due to the power limitation and the characteristics of human body. Wireless sensor network consist of sensor field and sink node. Sensor field are composed a lot of sensor node and sink node collect sensing data. Wireless sensor network has capacity of the self constitution by protocol where placed in large area without fixed position. Mobile sink node distribute energy consumption therefore network life time was increased than fixed sink node. The energy efficient is important matter in wireless body area network because energy resource was limited on sensor node. In this paper we proposed cluster topology algorithm for efficient data transmission in wireless body area network based mobile sink. The proposed algorithm show good performance under the advantage of grid routing protocol and TDMA scheduling that minimized overlap area on cluster and reduced amount of data on cluster header in error prone wireless sensor network based on mobile sink.

  • Korea has made a rapid economic development since the last three decades. This has helped Korea narrow the gap in health service differences in resource availability and in quality of care. However urban and rural differentials are still remarkable. This study has maintained that health status of rural residents is inferior to that of urban dwellers. Therefore, this study was carried out to develop policy measures for improving health services in rural areas. In order to achieve the objective of this study the authors collaborated closely and made field visits, interviews and conducted an extensive literature review regarding rural health services. The following policy options are recommended as a summary ; First, the quality of rural health personnel is a single most important factor influencing the level of rural health services. An innovative program for public health doctors to the internship and/or residency training program such as specialty board program of family medicine. Second, dissatisfaction regarding employment of public health doctors is problematic. More rational employment and deployment programs are needed to meet their personal desire. One way to do this is to make it wide open and competitive. Third this study shows how to increase physician productivity in the rural public health sector. Incentive system needs to be elaborated for the career development of rural health workers. University linked job opportunity as clinical professor is an example. Fourth, without straightening the function of health centers and subcenters, the future of rural health services is doomed to failure. Straightening primary health care is one way to enrich the program of public health facilities and reactivating the operation of health center/hospital is another. A close linkage of public facilities with private hospitals is a minimum requirement for the operation of health delivery system within a health district. Fifth, some measures are urgently required to enhance hospital services in medically underserved areas. Financial subsidy, tax exemption, long-term public loans and higher priority of health manpower deployment are some of them. Sixth, new health programs should be in tiated to meet changing needs of peoples in rural areas. Home health care program, hospice program, nursing home, residential program for the elderly are recommended.
