Under the influence of growing popularity of "hallyu" (Korean wave), corporates that have copyrights such as music, movie, drama as their core competitiveness are showing continuing growth. In Addition, they built on contents are rapidly growing, interests in protection and management of intellectual property rights linked to contents are growing. Global contents development corporates are making great efforts to create profits out of copyrights. They could utilize original contents to strengthen brand value use it to produce additional contents in current market. Also they take advantage of existing storyline of the contents and strong brand to explore new markets. This paper looks into Value articulation model by Professor James Conley and analyzed the firms that utilized intellectual property rights to extend the period of protection, strengthen their competitiveness and succeeded in breaking into new market by using the rights they possess. Also, this paper examines the usage of intellectual property rights and business expansion strategy of of Iconix, the Korean entertainment company, which gained tremendous popularity in last ten years using this model. In Value articulation model, Conley classifies the process of exploiting the portfolio of the single product's(or service's) intellectual property right for a period of time into three stages ; value transference, value translation, value transportation. Pororo's strategy of utilizing intellectual property right is suggestive to domestic entertainment companies. Under the influence of hallyu" (Korean wave), domestic contents such as movies, dramas and music are enjoying the high level of popularity recently not to mention animations. In reality, Korean entertainment companies who have no background or experience of Intellectual property rights are not creating enough added values compared to fast growing market. It is believed Iconix's intellectual property rights management strategy will suggest positive aspects to domestic companies. Moreover, I hope various intellectual property rights management strategies including Conley's value articulation are studied and they can make contributions to managing domestic entertainment companies.

The flexural performance of amorphous steel fibers having environmental and economy benefits due to relatively short manufacturing process were evaluated as well as that of hooked steel fibers by varing fiber length and volume fraction. Fiber lengths were 10 mm, 20 mm, 30 mm and fiber volume fractions were varied from 0.3% to 1.2%. Test results with flexural performance showed that mixing design needs to be careful because of relatively high volume of amorphous steel fiber compared to hooked steel fibers. High flexural strength was obtained from both longer fiber length and higher volume fraction. Residual strength and toughness of amorphous steel fiber were similar to that of hooked steel fiber, even though rapid dropping of applied load right after concrete matrix breaking. It can be judged that relatively high ability of energy dissipation around first cracking area relatively overcome rapid dropping of loading.

This study investigated the effects of electron beam irradiation on pathogens, quality, and functional properties of shell eggs during storage. A 1st grade 1-d-old egg was subjected to electron beam irradiation at 0, 1, 2, and 3 kGy, after which the number of total aerobic bacteria, reduction of inoculated Escherichia coli and Salmonella Typhimurium, egg quality, and functional properties were measured. Electron beam irradiation at 2 kGy reduced the number of E. coli and S. Typhimurium cells to a level below the detection limit (<$10^2$ CFU/g) after 7 and 14 d of storage. Egg freshness as measured by albumen height and the number of Haugh units was significantly reduced by 1-kGy irradiation. The viscosity of irradiated egg white was also significantly decreased by increased irradiation, whereas its foaming ability was increased. Electron beam irradiation also increased lipid oxidation in egg yolks. These results suggest that electron beam irradiation reduces the freshness of shell eggs while increasing the oxidation of egg yolk and improving important functional properties such as foaming capacity. Electron beam irradiation can also be applied to the egg breaking process since the irradiation reduces the viscosity of egg white, which can allow egg whites and yolks to be separated with greater efficiency.

This study aims at the elucidation of the distribution of longshore currents after wave breaking. Longshore currents have relations to the beach process and dispersion of contaminants in the nearshore region, thus the understanding of its. mechanism is very important. In the present study, using the electromagnetic current meter, the water particle velocity is measured in the 3-dimensional wave field and Eulerian mean velocity is obtained. At the same time, from the dispersion of tracer, the Lagrangian mean velocity is also obtained. It is observed that the longshore currents were confined within the surf zone and the maximum value of them exists in the surf zone. The longshore currents were considered to be constant toward the depth and we obtained the similar distribution of longshore currents between the measured value and the theoretical ones by Longuet-Higgins model.

In order to clarify the thermal and hygroscopic properties of indoor particulate matter (PM) in a semiclosed subway space, which is critically important for understanding of the distinctive particle formation processes as well as the assessment of their health effects, the size-resolved PMs (i.e., $PM_{2.5}$ and $PM_{10-2.5}$) were intensively collected on the platform of Miasageori station on the Seoul Subway Line-4. The elemental concentrations in soluble and insoluble fractions were determined by PIXE from the bulkily pretreated $PM_{2.5}$. The thermal and hygroscopic characteristics of individual particles were investigated via a combination of the unique pretreatment techniques (i.e., the high-temperature rapid thermal process and the water dialysis) and SEM-EDX analysis. Iron and calcium were unequaled in insoluble and soluble $PM_{2.5}$ fractions, respectively, with overwhelming concentration. The SEM-EDX's elemental net-counts for the pre- and post-pyrolyzed PMs newly suggest that magnesium and several elements (i.e., silica, aluminum, and calcium) may be readily involved in the newly generated subway fine PM by a high-temperature thermal processing when trains are breaking and starting. Through the water dialysis technique, it turned out that calcium has meaningful amount of water soluble fraction. Furthermore, the concentrations of the counter-ions associated with the calcium in subway $PM_{10-2.5}$ were theoretically estimated.

Cobalt-incorporated zeolitic imidazolate framework ZIF-8 was synthesized by a simple one-pot synthesis method at room temperature. Powder X-ray diffraction patterns and energy dispersive X-ray spectrum confirmed the formation of the bimetallic Co/Zn-ZIF structure. UV-Vis diffuse reflectance spectra revealed that the bimetallic ZIF had a lower HOMO-LUMO gap compared with ZIF-8 due to the charge transfer process from organic ligands to cobalt centers. A hydrolytic stability test showed that Co/Zn-ZIF is very robust in aqueous solution - the most important criterion for any material to be applied in photodegradation. The photocatalytic efficiency of the synthesized samples was investigated over the Indigo Carmine (IC) dye degradation under solar simulated irradiation. Cobalt incorporated ZIF-8 exhibited high efficiency over a wide range of pH and initial concentration. The degradation followed through three distinct stages: a slow initial stage, followed by an accelerated stage and completed with a decelerated stage. Moreover, the photocatalytic performance of the synthesized samples was highly improved in alkaline environment rather than in acidic or neutral environments, which may have been because in high pH medium, the increased concentration of hydroxyl ion facilitated the formation of hydroxyl radicals, a reactive species responsible for the breaking of the Indigo Carmine structure. Thus, Co/Zn-ZIF is a promising and green material for solving the environmental pollution caused by textile industries.

This study investigated the physical properties of warm up yarns and their knitted fabrics including the dye affinity and color fastness to washing of these knitted fabrics according to the various dyeing times and temperatures on dyeing process. The results were summarized as follows. The tenacity of Nylon/PP warm-up yarn was 4g/d and breaking strain was 4.5%. The wet and dry thermal shrinkages were higher than those of PET warm-up yarn. The maximum heat flow rate(Qmax) of Nylon/PP warm-up knitted fabric was lower than that of PET warm-up knitted fabric and heat keeping rate(a) of Nylon/PP warm-up knitted fabric was higher as 47% than that of PET warm-up knitted fabric. It was shown that the shape retention and wearing comfort of Nylon/PP warm-up knitted fabric were better than those of PET warm-up knitted fabric. The dye-affinity(K/S) of Nylon/PP warm-up knitted fabric showed maximum value at the dyeing condition of 40minute or 50minute dyeing time with $80^{\circ}C$ dyeing temperature, but PET warm-up knitted fabric showed maximum value at the 30minute or 40minute with $110^{\circ}C$ dyeing temperature. Finally, the color fastness to washing of Nylon/PP warm-up knitted fabric showed good value as between 4 and 5 grade.

The capacitive coupled plasma (CCP) has been extensively used in the semiconductor industry because it has not only good uniformity, but also low electron temperature. But CCP source has some problems, such as difficulty in varying the ion bombardment energy separately, low plasma density, and high processing pressure, etc. In this reason, dual frequency CCP has been investigated with a separate substrate biasing to control the plasma parameters and to obtain high etch rate with high etch selectivity. Especially, in this study, we studied on the etching of $SiO_2$ by using the pulse-time modulation in the dual-frequency CCP source composed of 60 MHz/ 2 MHz rf power. By using the combination of high /low rf powers, the differences in the gas dissociation, plasma density, and etch characteristics were investigated. Also, as the size of the semiconductor device is decreased to nano-scale, the etching of contact hole which has nano-scale higher aspect ratio is required. For the nano-scale contact hole etching by using continuous plasma, several etch problems such as bowing, sidewall taper, twist, mask faceting, erosion, distortions etc. occurs. To resolve these problems, etching in low process pressure, more sidewall passivation by using fluorocarbon-based plasma with high carbon ratio, low temperature processing, charge effect breaking, power modulation are needed. Therefore, in this study, to resolve these problems, we used the pulse-time modulated dual-frequency CCP system. Pulse plasma is generated by periodical turning the RF power On and Off state. We measured the etch rate, etch selectivity and etch profile by using a step profilometer and SEM. Also the X-ray photoelectron spectroscopic analysis on the surfaces etched by different duty ratio conditions correlate with the results above.

On 31 July 2014, there was a localized torrential rainfall ($58.5mm\;hr^{-1}$) caused by a strong convective cell with thunder showers over Daegwallyeong. In the surface synoptic chart, a typhoon was positioned in the East China Sea and the subtropical high was expanded to the Korean peninsula. A WRF (Weather Research and Forecasting) numerical simulation with a resolution of 1 km was performed for a detailed analysis. The simulation result showed a similar pattern in a reflectivity distribution particularly over the Gangwon-do region, compared with the radar reflectivity. According to the results of the WRF simulation, the process and mechanism of the localized heavy rainfall over Daegwallyeong are as follows: (1) a convective instability over the middle part of the Korean peninsula was enhanced due to the low level advection of warm and humid air from the North Pacific high. (2) There was easterly flow from the coast to the mountainous regions around Daegwallyeong, which was generated by the differential heating of the insolation among Daegwallyeong and the Yeongdong coastal plain, and nearby coastal waters. (3) In addition, westerly flow from the western part of Daegwallyeong caused a strong convergence in this region, generating a strong upward motion combined by an orographic effect. (4) This brought about a new convective cell over Daegwallyeong. And this cell was more developed by the outflow from another thunderstorm cell to the south, and finally these two cells were merged to develop as a strong convective cell with thunder showers, leading to the record breaking maximum rainfall per hour ($58.5mm\;hr^{-1}$) in July.
