  • The purpose of this study is to build fundamental data for the classification of landscape type as a base for landscape planning and management practices. To do this, prior dissertations and landscape plan reports were analyzed, which presented the classification criteria for landscape type. Based on this, classification criteria for landscape type which could be usable in zoning ordinances has been suggested. The result is as follows: Firstly, in landscape analysis and assessment study based on ecological and formal aesthetic models, landscape type is classified by the character of the landscape element. Secondly, there is no logical classification of landscapetype in urban landscape planning according to mixed use of landscape type for analysis and planning. It is therefore difficult to identify the object of landscape planning, which is intimately linked with the shortage of concrete practice for landscape management. In connection with this issue, classification criteria for landscape type are suggested based on utility in landscape planning. This could be divided into internal criteria and external criteria. The former are land-use, topographical characteristics, characteristics of the view object, and landscape elements while the latter are viewpoint, distance to view object, and urban form. Applying the landscape type classified by the criteria suggested in this paper, it is possible to manage an entire urban area. In addition, landscape type could be reference data for operating a zoning system.

  • Park planning is done in a way to satisfy various expectations, including providing green space and offering urban space with specific and detailed strategies. This study focuses on large-scale parks that have been built since 2000 or that are going to be built. Their significance in the city was analyzed along with strategic characteristics for designing urban parks, and implications are suggested. First, the design aspects of urban parks have gradually tended towards flexibility for adapting to the diverse surrounding environments. Relating the parks to the surrounding area is realized through connection with facilities or planning to process the border area smoothly. Second, unlike in the past, urban parks are not just simply used as a resting space but play other productive and complex roles in the urban space for healing in the community. Third, six design strategies are being applied in these parks through mutually complex relations. Relations with external parties and planning inside the parks add more importance to the park for the community. Fourth, the changes of vertical time are reflected in park planning strategies and tend to form a floor plan. This is associated with growing park planning and is being realized as a major characteristic in urban park planning strategies.

  • The welfare system and the direction of the welfare policy have been unable to escape greatly from the frame of the past against the facts that the external environments of the national economy of the world including Korea have been changing in quick and rapid speed. Such results have caused the issues related with the welfare, economy and society ended in the ideological collision in connection with the goals of the policy, the right agreement between the policies lacked, and the intervention and conflict between the interest group concerning the policy continued. Social policy of Korea in the past had the level of complementing the parts which could not be solved through the growth. Employment creation had been achieved continuously backed up by the high rate of growth. And the low aging level, the young population structure, and the high rate of childbirth had been the structures that made such achievement possible. New economic, social and welfare environment at home and abroad has been requesting new change in welfare policy. Goal of the economic and social policy is to construct the safe economic and social system. And what has been requested has been the formation of the economic and social policy orienting the welfare nation in form of social investment and welfare expansion. Also the direction in strengthening the welfare system of Korea shall have the balance between the protection and activation strength with the necessity of converting to the prevention welfare from the post welfare. Also the public part, market, the 3rd sector and the share of the role of an individual shall be achieved. And what is needed is the achievement of the transfer from the paradigm of residual welfare to the universal welfare. And such improvements of the welfare system will be able to elevate the possible continuity of the system in long term basis through the improvement of the welfare system.

  • The high-tension bolted joints are clamped by the axial force which approaches the yielding strength. The introduced axial force is transmitted to the connection members pass through washer. The transferred load in connections is balanced to the compressive stress of plates, axial force in bolts and the external loads. In this mechanism, the compressive stress and slip load we dominated by the effective stiffness of bolted joints and plates. In general the effective stiffness is specified to product to the effective area and elasticity modulus in connections. In this reason, the conic projection formular which is assumed that the axial force in bolts is distributed to the cone shape and that region is related to the elastic deformation mechanism in connections, was proposed. But it conclude what kind of formula is justified. Therefore in this paper, the fatigue tests are performed to the high tension bolted joints and inspected to the phase on the friction face. And using the FEM and numerical method, it is analyzed and approximated to the compressive stress distribution and its region. Moreover, it is estimated to the effective area and to the relation the friction area to the effective compressive distribution region.

  • Recently, the web service environment has changed from document-centered to data-oriented focus, and the Linked Open Data (LOD) exists at the core of the new environment. Specific procedures and methods were examined to build the LOD of records information in accordance with this trend. With the service sustainability of small-scale archive in consideration, an exemplification on LOD building process by utilizing open source software was developed in this paper. To this end, a 5-step service framework for LOD construction was proposed and applied to a collection of diary records from 'Human and Memory Archive'. Proof of Concept (POC) utilizing open source softwares, Protege and Apache Jena Fuseki, was conducted according to the proposed 5 step framework. After establishing the LOD of record information by utilizing the open source software, the connection with external LOD through interlinking and SPARQL search has been successfully performed. In addition, archives' considerations for LOD construction, including improvement on the quality of content information, the role of the archivist, were suggested based on the understanding obtained through the LOD construction process of records information.

  • The industrial control system (ICS) has operated as a closed network in the past, but it has recently been linked to information and communications services and has been causing damage due to cyber attacks. As a countermeasure, the Information Communication Infrastructure Protection Act was enacted, but it cannot be applied to various real control environments because there is only a one-way policy-from a control network to a business network. In addition, IEC62443 defines an industrial control system reference model as an international standard, and suggests an area security model using a firewall. However, there is a limit to linking an industrial control network, operating as a closed network, to an external network only through a firewall. In this paper, we analyze the security model and research trends of the industrial control system at home and abroad, and propose an industrial control system security model that can be applied to the actual interworking environments of various domestic industrial control networks. Also, we analyze the security of firewalls, industrial firewalls, network connection equipment, and one-way transmission systems. Through a domestic case and policy comparison, it is confirmed that security is improved. In the era of the fourth industrial revolution, the proposed security model can be applied to security management measures for various industrial control fields, such as smart factories, smart cars, and smart plants.

  • The palynological study of 31 taxa of Korean Artemisia L. was carried out to evaluate their taxonomic characteristics and to determine the relationships among the taxa. The size and shape of the pollen are not used as characteristics to classify the taxa of Korean Artemisia L., but the granule distribution ands pinule connection on the exine were useful for an interspecific classification and for reflecting the relationship between some taxa. It is considered that Artemisia pollen has evolved from a connected spinule and a nearly psilate surface into 1) a connected spinule and a granule surface, 2) a disconnected spinule and a granule surface, 3) a disconnected spinule and a dense granule surface. These pollen characteristics with external morphological characteristics, a geographical distribution and a somatic chromosome number are considered to be good characteristics for distinguishing the relationship of some taxa, such as the A. japonica group (A. hallaisanensis, A. angustissima, A. littoricola) and the A. sacrorum group (A. sacrorum var. sacrorum, A. sacrorum var. incana, A. sacrorum var. iwayomogi).

  • The purpose of this study was to analyze the effect of infographic instruction to promote the use of the scientific model in the 'lens' unit of elementary science textbooks. The participants were $6^{th}$ grade students(n=53) of G elementary school in G city, Gyeongsangnam-do. For this study, the lesson plan of the 'lens' unit consisted of three steps as investigation of students' prior concept about the lens, scientific model construction activity, and infographic construction activity. We then analyzed the results of this study from three perspectives: the scientific concept, scientific model, and infographic. Before the lesson, students focused on the external shape and material of the lens in prior concept of it. However, after the scientific model construction activity and infographic construction activity, students' scientific concept about the lens improved in the categories of features of lens, features of glasses, light path, and applications of the lens. In terms of the scientific model, use of type and frequency of scientific model increased more in the infographic construction activity than the scientific construction model activity. Also, in terms of infographic, the two infographic types as function based infographic and connection based infographic used more than non-infographic in the infographic construction activity. Also, the frequency of Gestal theory's visual perception increased more in the infographic construction activity than the scientific model construction activity.

  • This study analyzes a correlation between organizational commitment, work values, job satisfaction and loyalty of the middle management in hotel enterprises. In other words, this research aims at drawing up theoretical and working-level implication through establishing the competition model of parameters and independent variables, which have an effect on loyalty of the middle management in hotels. Analysis showed that work values of the middle management play not a key role to mediate between organizational commitment and job satisfaction, and that internal values are higher than external values in route analysis of work values. Meanwhile, it was analyzed that the middle management of hotels make a long-service commitment with great satisfaction on the job. But there was no connection between their job satisfaction and loyalty. Consequently, it was confirmed through the analysis of the competition model that they rather attach significance to internal values and specificity of the hotelier than their satisfaction with work because of economic stability, and the loyalty of the middle management responds sensitively to the organizational commitment variables as a permanent job, sense of belonging, self-esteem.
