Purpose: Laws and regulations of land use are enormous, and the appliance of regulations is overlapped redundantly. Therefore, there are many problems such as time consuming in the process, limiting individual property rights, and interrupting enterprises' economic activities. This study will discuss problems of redundant regulations of land use and its improvement by figuring out current regulations of land use in Gyeonggi-do, one of provinces which applies the most various regulations of land use. Method: This study reviews laws on national land-use planning system and characteristics of land-use regulation in Korea. The extent of the review is limited to "framework act on the regulation of land use" with categories of national land, urban planing, architecture, etc. Through case studies in Gyeonggi-do, the status and problems of redundant regulations of land use are defined. For example, it is overlapped in "Seoul Metropolitan Area Readjustment Planning Act", Development Restriction Zone, Paldang Special District, and so on. It is mainly referred to 2015 Gyeonggi-do land-use restriction map. Result: First, Gyeonggi-do confronts many problems related to the development restrictions and the financial increasement for environmental management by redundant regulations. The development restrictions include supplying additional land for industrial use, relocating colleges, and height limitation relating to military facilities. Second, in order to organize redundant regulations, it is required to combine similar regulations and adjust through communication system among other departments. Third, regulations should consider unique local condition of each district. Lastly, efficient application of regulations is necessary so as to maximize the function of land, protect individual property rights, and stimulate local development.

This paper proposes improved detection schemes for concealed micro-electronic devices using clustering and classification of radio frequency harmonics in order to protect intellectual property rights. In general, if a radio wave with a specific fundamental frequency is propagated from the transmitter of a classifier to a concealed object, the second and the third harmonics will be returned as the radio wave is reflected. Using this principle, we exploit the fuzzy c-means clustering and the ${\kappa}$-nearest neighbor classification for detecting diverse concealed objects. Simulation results indicate that the proposed scheme can detect electronic devices and metal devices in various learning environments by efficient classification. Thus, the proposed schemes can be utilized as an effective detection method for concealed micro-electronic device to protect intellectual property rights.

Despite of continuous efforts to crack down on piracy using penalties and regulations, this unauthorized piracy market is still enormous. Since the moral hazard about this phenomenon is pervasive and continually upsets the major intellectual property markets, an alternative plan is required. The purpose of this study is to provide an objective insight for factors that affect people's digital video piracy behavior. The following two research propositions were the focus: what psychological factors affect piracy behavior and how are these factors related to one another? In order to accomplish the research aims, we reviewed literatures on the current state of piracy in South Korea, characteristics of digital contents, studies on criminal psychology and behavioral theories. Previous research in the fields of criminal theory indicated that neutralization, a form of rationalization, would help explain digital piracy intentions. Thus, this study developed a model that explains effects of neutralization techniques and tested the possibility of an integrated model with other behavioral theory such as TPB and TIB. Empirical results of the study(368 sample collected) showed that all the factors in TPB including Attitude to Piracy(+), Subjective Norm(-), Perceived Behavioral Control(+) had a significant impact on Piracy Intention. Moreover, two neutralization techniques, Condemn the Condemners(+) and Appeal to Higher Loyalties(+), had a significant effect on Piracy Intention. In addition, Past Behavior had strong impacts on Attitude(+), Perceived Behavioral Control(+) and Piracy Intention(+). In terms of Expected Profit, it had an impact on Attitude to Piracy positively. These findings suggest implications for protecting the current intellectual property markets, with many stakeholders in movies and media industries. There are some limitations as followed: first, the study did not consider other neutralization techniques, low level of deterrence and the other expected results despite the possibility of their effects. Second, the study needs improvements through longitudinal research because the cross-sectional research could not rule out the alternative explanations.

Objectives : Medical treating with eating foods is one of important therapies in East Asian traditional medical knowledge and is referred as a therapy to treat diseases through foods. Since the food cannot be separated from ordinary people living, the medical treating with eating foods is a therapy with strong locality and contains many autogenous parts. Methods : Recently, the world is showing much interest for genetic resources, and the concept of intellectual property is rapidly expanding as the field of 'new knowledge property right' as well. Thus, the knowledge of medical treating with eating foods recently draws much attention in the economic aspect beyond the scholarly interest for traditional medicine. Here, I would like to summarize and report the contents related to medical treating with eating foods on "Yi, SeikKan experience prescriptions" which was discovered before. Results & Conclusions : First, medical treating with eating porridge on "Yi, SeikKan experience prescriptions" is classified into one with nonglutinous rice as the main ingredient and the other with other grains as the main ingredient. It is differently utilized depending on the nature of the grain. Second, medical treating with eating rice on "Yi, SeikKan experience prescriptions" was born from our nation's unique way of living and is classified into one way to eat rice mixed with ground medicinal herbs, another one to cook and eat rice with mixed grains and the other way to use as the external application. Medical treating with eating rice is assumed to replace the meal. Third, "food section" was given separately and discussed in this book. There were some parts different from existing medical knowledge due to the accumulation of experience using medicinal herbs. Fourth, we should pay attention to experience a book on medicine where vibrant medical information has been recorded in order to discover and process our traditional knowledge resources as a useful form.

This study investigates the microstructure and wear properties of cermet (ceramic + metal) coating materials manufactured using high velocity oxygen fuel (HVOF) process. Three types of HVOF coating layers are formed by depositing WC-12Co, WC-20Cr-7Ni, and Cr3C2-20NiCr (wt.%) powders on S45C steel substrate. The porosities of the coating layers are $1{\pm}0.5%$ for all three specimens. Microstructural analysis confirms the formation of second carbide phases of $W_2C$, $Co_6W_6C$, and $Cr_7C_3$ owing to decarburizing of WC phases on WC-based coating layers. In the case of WC-12Co coating, which has a high ratio of $W_2C$ phase with high brittleness, the interface property between the carbide and the metal binder slightly decreases. In the $Cr_3C_2-20CrNi$ coating layer, decarburizing almost does not occur, but fine cavities exist between the splats. The wear loss occurs in the descending order of $Cr_3C_2-20NiCr$, WC-12Co, and WC-20Cr-7Ni, where WC-20Cr-7Ni achieves the highest wear resistance property. It can be inferred that the ratio of the carbide and the binding properties between carbide-binder and binder-binder in a cermet coating material manufactured with HVOF as the primary factors determine the wear properties of the cermet coating material.

In this study, a magnetic adsorbent was synthesized by growing ferrite nanoparticles substituted with metals (Me = Co, Mn, Ni) on zeolite 4A for the efficient separation of waste adsorbents present in the solution after the adsorption of Cu(II). The metal ferrite grown on the surface of zeolite was prepared by solvothermal synthesis. Characteristics of the magnetic adsorbent were analyzed by X-ray diffractometer (XRD), scanning electron microscopy (SEM) and physical property measurement system (PPMS). The saturation magnetization of the A type zeolite coated with Co-ferrite (CFZC) was the highest at 5 emu/g and the Cu(II) adsorption performance was also excellent. The adsorption results of Cu(II) on CFZC were well fitted by the Langmuir model at 298 K. Also, the adsorption of Cu(II) on CFZC follows a pseudo-second order kinetic. The Gibbs free energy values (${\Delta}G^0$) ranging from -4.63 to -5.21 kJ/mol indicates that the Cu(II) adsorption is spontaneous in the temeprature range between 298 and 313 K.

Gas hydrates are ice-like crystalline compounds that form under low temperature and elevated pressure conditions. Although hydrate formation can pose serious flow-assurance problems in the gas pipelines or facilities, gas hydrates present a novel means for natural gas storage and transportation with potential applications in a wide variety of areas. An important property of hydrates that makes them attractive for use in gas storage and transportation is their very high gas-to-solid ratio. In addition to the high gas content, gas hydrates are remarkably stable. The main barrier to development of gas hydrate technology is the lack of an effective method to mass produce gas hydrate in solid form. The first objective of this study is investigating the characteristics of gas hydrate formation related to several factors such as pressure, temperature, water-to-storage volume ratio, concentration of SDS, heat transfer and whether stirred or not respectively. And the second objective is clarifying the relation between the formation efficiency and each factor in order to find the proper way or direction to improve the formation performance.

MCM-41(Mobil's Composition of Matter-41) and expanded graphite(EG) were investigated as potential adsorbents for heavy metal ions including Pb(II), Cu(II) and Ni(II) in various aqueous chemistries. MCM-41 showed shorter equilibrium times and higher adsorption capacities for all three heavy metal ions compared to expanded graphite. The adsorption of three heavy metal ions was significantly affected by the solution pH due to the competition with $H_{3}O^{+}$ at lower pH and precipitation at neutral or higher pH. Adsorptions of heavy metal ions onto MCM-41 and expanded graphite were successfully described with the pseudo-second-order model. During the competitive adsorption of three heavy metal ions, the selectivity of Pb(II) was highest and almost same selectivity was observed with Cu(II) and Ni(II) when MCM-41 was used as an adsorbent, while the expanded graphite exhibited the highest selectivity to Pb(II), followed by Ni(II) and Cu(II).

Gwanghwamun was dismantled and displaced to the east side of the palace, at that time, the Chosun Government General Building was constructed in the Gyeongbokgung palace. After the Korea war, it remained as a stonework as a result of the fire. In 1968, The Gwanghwamun came back in front of the palace. Then, why it was rebuilt in the 3rd Republic period? What was the reason for selecting concrete? Since the May 16 coup, the military regime had been utilized palace and surrounding urban space to show a visible practice of modernization. Attempting the combination of modern technology in the 1960s and traditional cultural property and reconstructing a city as a pretext called Cultural Heritage conservation was a typical mechanism of the 1960s. In this study, I start by assume that reconstructing Gwanghwamun(1968) was a part of project to change the surrounding urban space of Gwanghwamun than to preserve cultural assets. Two main contributions of the study are following. First, I collect availabe data on the reconstructing surrounding urban space of the Gwanghwamun and re-organize them in chronological order to make them as fragments of a map. Second, I analysis and identify the nature and phase of the Gwanghwamun reconstruction.
