The Ministry of Environment of the Republic of Korea set up 'the $2^{nd}$ Fundamental Plan for Wetlands Conservation' to facilitate systematic surveys and management of various national wetlands and to promote sustainable conservation and use of those wetlands. The mid-term fundamental plan was established in accordance with the Article 5 of the Wetland Conservation Act, which spans 5 years from 2013 to 2017 and covers national wetlands including inland wetlands and coastal wetlands stated in the Act. The fundamental plan aims to promote the wise use of wetlands through establishing policies for sustainable conservation based on the assessment of implementation of the $1^{st}$ Fundamental Plan, setting up a scientific framework for establishment and implementation of national wetland policies by improving wetland survey systems and enhancing basis wetland data, improving the ecological health of wetlands and securing biodiversity conservation of wetlands by strengthening conservation and management system of national wetlands, and through raising public awareness and diversify education and promotion tools. The main objectives of the $2^{nd}$ Fundamental Plan is to revise the entire Wetland Conservation Act, to create a new monitoring system of national inland wetlands, to upgrade the national wetlands inventory, to reflect the 'Ecological Map' for promoting precautionary management of wetlands, to improve the 'Wetland Restoration and Management' system to build wetlands resilience, and to systematize the wise use of wetlands that benefits local people. As the Ministry of Environment plans to establish its other master plan for wetland conservation based on the $2^{nd}$ Fundamental Plan, this document introduces the $2^{nd}$ Fundamental Plan to stakeholder and wetland professions.

Class hierarchies often constitute the backbone of object-oriented software. Their quality is therefore quite crucial. Building class hierarchies with good qualify is a very important and common tasks on the object oriented software development, but such hierarchies are not so easy to build. Moreover, the class hierarchy structure under construction is frequently restructured and refined until it becomes suitable for the requirement on the iterative and incremental development lifecycle. Therefore, there has been renewal of interest in all methodologies and tools to assist the object oriented developers in this task. In this paper, we define a set of quantitative metrics which provide a wav of capturing features of a rough estimation of complexity of class hierarchy structure. In addition to, we suggest a set of algorithms that transform a original class hierarchy structure into reorganized one based on the proposed metrics for class hierarchy structure. Furthermore, we also prove that each algorithm is "object-preserving". That is, we prove that the set of objects are never changed before and after applying the algorithm on a class hierarchy. The technique presented in this paper can be used as a guidelines of the construction, restructuring and refinement of class hierarchies. Moreover, the proposed set of algorithms based on metrics can be helpful for developers as an useful instrument for the object-oriented software development.velopment.

As coming Senior-Shift age, senior users are regarded as one of the importance user groups in the library. This study is to find the usage patterns and needs of libraries and digital libraries by 152 seniors and to compare with young-old age (baby boom generation) and elderly age. As a result, total seniors visited regularly and preferred political & social, religion & philosophy, and history & geography. While the baby boom generation are using the economy & finance, art & culture compared to the older. And the baby boom generation visit for self-development and the older visit for leisure purposes. Secondly, If the search fails, the baby boomers control the results themselves, while the older is more turn to the librarians. It can be described as the need for a librarian exclusively responsible for the senior. Thirdly, senior have difficulties in access and use of search aided tools or functions. Therefore, this study suggested that it is necessary to build an intuitive interface using the help and menu descriptions for senior who have poor access to convenience and define functions.

The purpose of this study is to research the effect of using analogies in high school earth science classes. According to the usage of TWA model, three types of teaching strategies were developed: text developer-generated, teacher-generated, and student-generated analogies. The model described in this paper began with a task analysis of highschool science textbooks for grade 10 to identify how the textbook authors used analogies to explain plate tectonics concepts. In this study, 210 students were sampled from first graders of high school. After 7 classes, the consciousness of students was investigated with questionnaires. The results are as follows: 1. Many plate-tectonics analogies are used in high school science textbooks (total 25). Teachers and authors construct effective analogies to help students build on their relevant knowledge by applying it to new knowledge acquired from textbooks. 2. Analysis of the data indicate that instruction using student-generated analogies was more effective than others. But in the class in conveying complicated concepts (ex. transform fault), teacher-generated instruction was effective. Teachers need to be aware of the weakness of using analogies in order to select the most appropriate analogies. 3. Making analogies in general, as well as using analogies have systematic steps. Analogies should be used after considering student's preconception, teacher's consciousness and text author's intention to use analogies as powerful instructional tools.

Objectives The purpose of this review is to investigate studies of Scolopendrid pharmacopuncture and the evidence of it's effects in order to suggest a better research method in the future. Methods We retrieved numbers of clinical studies about Scolopendrid pharmacopuncture from 7 Korean web databases, using key words such as 'Scolopendrid', 'Scolopendrid AND Pharmacopuncture'. This study had been conducted from 1st May 2013 to 31th July 2013. Controlled studies and case studies were only used for this study. Clinical studies that we picked from the databases were classified according to the diseases that those studies are about, and from these clinical studies, we are to research what has to be improved generally in clinical researches. Results 18 case studies, 4 controlled studies had been under research. Scolopendrid pharmacopuncture has a therapeutic effect mainly in musculoskeletal and neurological diseases such as herniated intervertebral disc, carpal tunnel syndrome, swollen leg, feeling of cold on legs, wrist ganglion, lateral epicondylitis, radial nerve palsy, cervical myelopathy, cauda equina syndrome, postauricular pain; as an early symptom of Bell's palsy, pain of popliteal part, gout, plantar fasciitis, cellulitis, frozen shoulder, pain of hip adductors. However objectivity and reliability of the Scolopendrid pharmacopuncture studies still remains controversial. Conclusions It has been suggested that there are positive effects of Scolopendrid pharmacopuncture therapy in treating specific diseases (especially neuromusculoskeletal diseases). However, this narrative review can't conclude and prove that the Scolopendrid pharmacopuncture has positive effectiveness on these diseases unlike systematic review. So, in order to put Scolopendrid pharmacopuncture therapy to use for many kinds of diseases in more reasonable ways, it is essential to build well-designed clinical research tools. In the future, abundant case studies, more follow-up trials and randomized controlled trials based on the korean medicine should be done to use Scolopendrid pharmacopuncture for a clinical purpose.

Due to the development of information and communication technology, the number of new / variant malicious codes is increasing rapidly every year, and various types of malicious codes are spreading due to the development of Internet of things and cloud computing technology. In this paper, we propose a malware analysis method based on string information that can be used regardless of operating system environment and represents library call information related to malicious behavior. Attackers can easily create malware using existing code or by using automated authoring tools, and the generated malware operates in a similar way to existing malware. Since most of the strings that can be extracted from malicious code are composed of information closely related to malicious behavior, it is processed by weighting data features using text mining based method to extract them as effective features for malware analysis. Based on the processed data, a model is constructed using various machine learning algorithms to perform experiments on detection of malicious status and classification of malicious groups. Data has been compared and verified against all files used on Windows and Linux operating systems. The accuracy of malicious detection is about 93.5%, the accuracy of group classification is about 90%. The proposed technique has a wide range of applications because it is relatively simple, fast, and operating system independent as a single model because it is not necessary to build a model for each group when classifying malicious groups. In addition, since the string information is extracted through static analysis, it can be processed faster than the analysis method that directly executes the code.

The application of magnetic method for archaeoprospection has been carried out through two archaeological areas in Egypt, Abydos and Abu Sir, In order to find out tile ancient Egyptian archaeological features. The magnetic work at the selected archaeological site of Abydos area was carried out by gradiometer survey, while magnetic work at the selected archaeological site of Abu Sir area was carried out by gradiometer survey and magnetic susceptibility measurements. A gradiometer survey with raster of 0.5 m/0.5 m has been carried out on a surface area of $9600 m^2$ at Abydos area to relocate the buried Solar Boats. The magnetic data were processed using Geoplot software to treat the field noises and enhance the quality of the obtained images. The final magnetic images indicate the existence of 12 Solar Boats as well as tombs, remains of ancient rooms and walls. All of them are expected to belong to the Middle Kingdom, particularly from the 18th to 20th Dynasties. Two magnetic tools have been applied over a selected site of $25600 m^2$ at Abu Sir area in order to detect the hidden archaeological features nearby the Sun Temple. The acquisition of the magnetic data was initiated by the measurements of the topsoil magnetic susceptibility of 272 samples collected from the whole studied area, and then followed by the gradiometer survey to measure tile vertical gradient of the geomagnetic field over an area of $14400 m^2$. The magnetic susceptibility results show the presence of high concentration at the middle part of the study area with a little extension to the south western side, with maximum value of about $36{\times}10^5$ SI. They may indicate the proximity of ritual monuments. Also, they offered the site of interest for carrying out a gradiometer survey. The gradiometer results show tile existence of numerous distributed archaeological features made of mud-bricks with different shapes and sizes. They may indicate tombs, burial rooms, dissected walls; all of them are expected to belong to the 5th Dynasty of pharaohs, who used to build their buildings by mud bricks. The depth of the expected buried archaeological features has been estimated from tihe gradiometer. It is around 1.2m for deep features and 0.42 m for shallow features.

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.

With the increasingly diverse, sophisticated and complex character animations that can be represented in 3D animations, the importance of rigging, which can most directly affect animating quality, is becoming more and more important. In addition, rapidity is another crucial aspect of 3D animation production. So, the importance of technical director's role which is accurate and rapid handling of rigging pipeline building and immediate application and, corrections of errors during the longest and manpower consuming animation production is more becoming key. Baek Ji Won and Kim Jae-woong (2014) said, "The technical director is adding new importance to the new job, which is created by 3D animation, in conjunction with the limited production period, manpower, budget and production process." Most major overseas studios are developing in-house software to handle rigging and animation processes. Software development code is used to freely develop and modify production pipelines in accordance with the direction of the work. They are making efforts to build an optimal environment for animators. However, too many efforts and ineffective efforts have been made to develop, adapt, and stabilize the rigging process for small producers, creators, and students who do not have the capacity to develop their own in-house software or hire a technical director. This study suggests the most suitable auto-rigging tool among the many auto-rigging tools released in the market, and suggests the most accurate and quick auto-rigging process setting method for those who have insufficient knowledge about 3D character rigging. The efficiency of use of auto-rigging tool was examined.
