The aims of this study are to investigate two main problems for the hypothetico-deduction method and to develop a scientific inquiry model to resolve these problems. The structure of this scientific inquiry model consists of accounts of the context of discovery and justification that the hypothetico-deduction holds as two main problems : 1) the heuristic flaw in the hypothetico-deduction method is that there is no limit to creating hypotheses to explain natural phenomena; 2) Logically, this brings into question affirming the consequent and modus tollens. The features of the model are as follows: first, the generation of hypotheses using an analogical abduction and the selection of hypotheses using consilience and simplicity; second, the expansion phase as resolution for the fallacy of affirming the consequent and the recycle phase as resolution for modus tollens involving auxiliary hypotheses. Finally, we examine the establishment process of Copernicus's Heliocentric Hypothesis and the main role of the history of science for the historical invalidity of this scientific inquiry model based on three examples of If/and/then type of explanation testing suggested by Lawson (International journal of science and Mathematics Education, 2005a, 3(1): 1-5) We claim that this hypotheticho-deduction process involving abduction approach produced favorable in scientific literacy rising for science teacher as well as students.

This study analysed the effect of inheritance tax on households in reality and to improve it if there is an unreasonable aspect compared to countries around the world. The study conducted a one-on-one face-to-face survey on adults living in major cities across the country for 31 days from 1^st of September to 10^th of October, 2022. The collected data was analysed using SPSS 25.0 version and noted that 1) they preferred the abolition of inheritance tax, but hoped to improve it when maintaining it, 2) it was necessary to expand the deduction limit, abolish spouse deductions, and 3) prefer the inheritance acquisition tax system. Finally, it was found that they wanted to Extension of installment period of inheritance tax and introduce the tax deferred system.. This suggests that there is a perception that the overall revision of the inheritance tax system is necessary to maintain the inheritance tax. The significance of the study is to provide the basis for discussions on the improvement of the inheritance tax system in Korea, which does not reflect reality.

Transmission loss of specimen is calculated by measuring energy of incident and transmission and using reverberant room of large size. But normal measurement of transmission loss has trouble because it is actually demanded that large area and specimen of certain size is satisfied with condition of diffused sound field. Especially, in case of mechanical component, interested frequency band is mid-frequency band between 500 ~ 2k Hz, and it is used to be available to minimize a reverberation chamber under conditions satisfying acoustic one because production of specimen for transmission loss measurement has limit. But, as in semi-reverberation room, it is difficult to satisfy condition of diffuse sound field and modification factor is applied to complement that. Correction factor when measuring transmission loss using semi-reverberation chamber is required accuracy because it works as main factor determining reliability of reuslts on transmission loss. In this study, it is analyzed that an effect on correction factor based on varying materials and sizes of specimens in order to deduction of it. Also It is confirmed that applied by elicited correction factor with actual railway vehicle's floor has reliability.

According to the recent judgment of Supreme Court, in case when the National Health Insurance Service pays the insurance to a victim of torts, and then subrogate the victim's claim for damages, the scope of institution's subrogation should be limited to the amount of the assailant's responsibility rate of the institution charge, and the amount of compensation claimed by the victim to the assailant should be calculated in the method of contributory negligence after deduction. The court has judged that the institution could subrogate the whole amount of institution charge in the limit of assailant's damages, and the method of deduction after contributory negligence should be applied when calculating the assailant's damages to the victim. Supreme Court decision is greatly significant in the aspect of harmonizing the nature of health insurance as property right and social insurance as the beneficiaries could get additional supplement, and also seeking the balance between insurer and beneficiary. With the changed legal principles of Supreme Court in the scope of institution subrogation like this, the necessities to complement the litigation relation, legislation, and institution were suggested.

The provision of spatial data is a key infrastructural requirement for the promotion of economic growth, environmental quality, social progress, etc. 4S technology integrates 4 kinds of systems that process spatial data: GIS (Geographic Information System), GNSS (Global Navigation Satellite System), ITS (Intelligent Transport System), and SIIS (Spatial Imagery Information System). Spatial data processing field is expected to get synergy effect and overcomes development limit of individual unit technology via 4S technology. This paper discusses both the development of 4S-kernel technology and the construction of 4S-based framework, In the development of 4S kernel technology, we will concentrate on the following issues: the development of 4S base components for reciprocity integration among GIS, SIIS, GNSS and ITS technologies, the development of 4S-Mobile S/W and H/W, 4S-Van components, and national LBS technologies. And in the construction of 4S-based framework, we will especially concentrate on the ISP for overall 4S technologies, the international cooperative research center, and the guide model deduction for supervision and certification of 4S projects. Finally, we examine about how the construction of 4S-baed framework affects 4S industry.

In this study, the implications for landscape architecture in the restoration Project of Cheonggyecheon will be shown through the analysis of factors for landscape architect scheme modification. The method of study consists of theoretical study, analysis of the plan and design of landscape architecture of the restoration project of Cheonggyecheon, and deduction of implications thereof. The controversial feints included the many difficulties in realizing the productive design of landscape architecture due to the selective collecting of public opinion and the problems of settling the complications, the design limit of the turnkey and MA systems, the lack of hydraulic knowledge and technology and the shortage of vegetation monitoring data and experimental materials. The alternative proposals are as follows: 1) there should be agreement between the government organization and the civil group, 2) in the turnkey bidding for the river restoration projects, the river restoration design based on the volume divided into some parts should be reconsidered in order to maintain consistency in the total design, 3) in order to maintain consistency in the planning policies, MA designs should also be introduced and applied from the first stage of the project through its completion, and 4) data such as the safe water level in case of flooding for the facilities and the vegetation and data in connection with the ecological restoration of river should be accumulated. If these controversies are not settled effectively, the river restoration project will be delayed due to complications with the citizens and wasted time and effort will result from the frequent design changes. In addition, landscape architecture in this kind of restoration project is bound to decrease in the future due to frequent changes in the hydraulic-centered design.

It is the most important thing of the overall VE that we create inventive ideas from idea phase in the design VE. However, it is hard that it take a long time and create a superior idea using Brainstorming. And, it was real to lodge an alternative plan proposed on the idea thinking phase, it is true that an alternative plan of existing simply costdown apply to a change and insert isn't different from an inventive idea deduction. Also creating alternative idea, many expert hold on to only his field and it was exposed a limit depend on a team's experience or intuition than technical solution. In this study, we analyzed the problem of the present design VE processing and analyzed the problem through a survey to an expert, and then we'll suggest a possibility for an efficient design VE.

The stagnation of unsold houses is recently aggravated due to domestic and overseas crisis of finance and real-sector economy and domestic housing construction is in serious difficulty. Thus, tax support is necessary for national housing construction. Due to the current tax exemption system of national housing, V.A.T. paid in the construction of national housing is not deducted. Namely, it is ascribed to consumer as it is reflected in the construction cost. This research intends to analyze the limit of V.A.T. tax exemption system, to present the necessity of applying zero rate and to calculate the scale of non-deduction of V.A.T. purchase tax amount for national housing by analyzing the construction site of apartment house of house constructor in order to analyze the effect of zero rate when it is applied on the basis of above ground. In the zero rate system, V.A.T. is not collected from the consumers like the present tax exemption system. However, the purchase tax amount borne in the construction of national housing is deducted totally. As purchase tax is deducted, constructor will promote supplying national housing thanks to the effect of solving financial difficulties and improving liquidity. Since the architecture cost and parceling-out price can be lowered due to the improved liquidity of constructor, the policy will actually help the people without house.

Korea's natural parks are managed by dividing them into four use districts: nature preservation district, natural environment district, cultural heritage district, and park village district within the park under the goal of 'conservation and sustainable use of natural parks'. However, the use districts divided in this way are designated by reflecting the results derived from the simple drawing overlapping method, and there is a limit in that objective and scientific evidence for this is insufficient. In addition, in Taeanhaean National Park, the case of this study, only a very small area of less than 1% of the nature preservation district is designated, and the natural environment district that serves as a buffer space is designated on an excessively wide scale, making it difficult to efficiently manage the national park. Therefore, the use district is not fulfilling its role. In this study, the purpose of this study was to present a method for analyzing the spatial characteristics of natural parks using environmental indicators and unsupervised learning analysis methods to set the use districts of natural parks. In this study, evaluation indicators that can evaluate the natural and human environments were derived, and the distribution patterns for each indicator were analyzed. Afterwards, by applying Self-Organizing Map (SOM) analysis, one of the unsupervised learning analysis methods, districts with similar characteristics were derived in Taeanhaean National Park, and the characteristics of each district were analyzed. As a result of the study, 7 districts with different characteristics were derived in Taeanhaean National Park, and by examining the contribution of each indicator together, it was possible to reveal that each district had different representative characteristics even though it was an adjacent area. This study evaluated natural parks by comprehensively considering the indicators of the natural and human environments. In addition, the SOM method used in the study is meaningful in that it can provide scientific and objective grounds for the existing zoning and apply it to the management plan.
