본 연구는 영화 소비 과정을 탐색하기 위해 영화 취향 및 영화 정보 이용 요인들, 인구사회 요인들을 투입해 영화 소비에 미치는 영향을 살펴보았다. 본 연구의 주요 결과들은 다음과 같다. 첫째, 영화 소비에 가장 큰 영향을 미치는 요인은 영화 취향으로 나타났다. 응답자들은 영화 취향 정도가 증가할수록 영화소비가 늘어나는 것으로 나타났다. 둘째, 영화 취향은 영화 정보를 인터넷으로 검색하거나 영화 블로그를 이용하는 행위에 유의미한 영향을 미치는 것으로 나타났다. 영화 취향 정도가 높을수록 인터넷으로 영화정보를 검색하거나 영화 블로그를 이용하는 것으로 나타났다. 한편, 영화 블로그를 이용하는 응답자들은 영화 소비가 늘어났던 반면 영화 인터넷 검색 여부는 영화 소비에 영향을 미치지 않았다. 셋째, 성별이나 소득과 같은 인구사회 요인들 중에서 성별 요인만 영화 소비에 정적인 영향을 미치는 것으로 나타났다. 여성 응답자일수록 영화 소비 정도가 증가했다. 반면, 소득 요인은 영화 소비에 영향을 미치지 않았다.

This paper presents the necessary elements and data flow in developing a monitoring system of energy usage for apartment houses with a Smart TV. Energy consumption data in each home are collected and analyzed in the HUB station by way of measuring instruments. And the amount of energy usage, such as electricity, gas, hot water, heating, water and other utilities are displayed through the Smart TV application. Energy consumption Database in the HUB station are processed and displayed in the browser of a Smart TV through XML, JAVASCRIPT and Flash. Smart TV users can get the energy consumption status through the energy consumption analysis display of the Smart TV application and improve the energy efficiency by comparing the usage patterns with neighboring houses. And the application display energy usage information, consumption ranking, rates to user as well. Furthermore, usage of last month or year can be compared to help to reduce the energy usage. The proposed system can provide the information about the amount of energy use to be reduced and the warning on the waste of energy.

이 연구는 한국 영화시장에서의 집중화 현상을 고찰하기 위해 스크린 규모와 흥행, 그리고 국적을 중심으로 이를 분석했다. 분석대상은 2005년부터 2019년까지 15년 동안의 연도별 흥행 100위권 영화로, 총 1,500편이다. 분석결과 스크린수는 매년 꾸준히 증가하는 추세였고, 스크린 집중화는 높은 수준으로 나타났다. 흥행 100위 기준 스크린 집중도는 2005년의 12%에서 30% 이상으로 상승했으며, 흥행 10위 기준에서는 2005년 21%에서 큰 상승폭을 보이며 2014년 이후 매년 50% 이상을 차지했다. 개봉 스크린 규모가 증가하면서 멀티플렉스는 흥행유인력이 높은 영화에 보다 많은 스크린을 할당했다. 오랫동안 스크린 독과점에 대한 비판이 있어왔지만 멀티플렉스는 2011년과 2012년 이후 이를 더 심화시키면서 한 편의 영화가 전체 스크린의 60% 이상을 차지하고 개봉되는 상황을 발생시키고 있다. 멀티플렉스의 이런 방식은 흥행 100위권 영화의 시장 점유율을 95%까지 상승하게 하고 있다. 또한 멀티플렉스는 한국영화보다 할리우드 영화에 보다 더 많은 스크린을 할당하는 경향을 보여주었다. 흥행성과가 높은 100위권을 대상으로 한 분석에서 영화 국적은 한국과 미국으로 집중된 것으로 나타났다. 이를 제외한 18개 국가의 경우 공급 측면에서 9.3%만 차지했다. 영화의 국적별 소비를 살펴보면, 두 국가로의 집중화 현상은 더 강하게 나타났다. 공급 차원에서 90.7%를 차지하고 있지만 소비 측면에서 96.6%를 차지했다. 공급에서의 집중화 현상은 소비에서의 집중화 현상과 정적인 상관관계를 보여주었고, 소비 측면에서의 집중화가 공급 측면보다 조금 더 높게 나타났다. 한국 영화시장은 스크린의 증가가 공급과 소비의 집중화를 심화한 사례로 드러났다.

Mechanical energy consumption during human running was studied. The subject was modeled by an eleven segment planar open linkage system and analyzed by Newtonian equations of motion from film data with a sampling rate of 50 Hz. The motion data from films were smoothed by lower 7 harmonics before analysis. And this study was tried for a normal male subject running on a concrete floor. The mechanical energy consumption was evaluated from the five different criteria suggested by others and a joint energy consumption criterion newly devised based on the muscle contraction.

We explored a new way of designing dynamic logic gates with low temperature polysilicon thin film transistors to increase the speed. The proposed architecture of logic gates utilizes the structural advantage of smaller junction capacitance of thin film transistors. This method effectively blocks leakage of current through the thin film transistors. Furthermore, the number of transistors used in logic gates is reduced thereby reducing power consumption and chip area. Through HSPICE .simulation, it is confirmed that the circuit speed is also improved in all logic gates designed.

In order to reduce the energy consumption of the building, much effort is being made. The problems are that excessive solar radiation in summer and the heat loss in winter by the increase of window area. To prevent this problems, government limited the window area ratio or the performance of windows in new buildings. In order to reduce energy consumption of the existing buildings, the window film insulation is spotlight because the window film insulation was simple to installation. This study confirmed the performance of the window film insulation and affect to heating & cooling load of buildings. The impact of the window film insulation coating was confirmed by experiment. And this study confirmed the annual heating & cooling load by simulation. As a results, the surface temperature of coated window was higher than the surface temperature of existing window. The window film insulation was increased surface temperature of window. And this study confirmed that the increased surface temperature was slightly affected the room air temperature through experiment of the insulation box. The results of the heating and cooling load by simulation, this study confirmed that the case of coated window film insulation decreased cooling load in summer and increased heating load in winter. Also the annual total heating & cooling load was increased a little in the case of coated the window film insulation.

Fuel wall film effects power output and cycle deviation by changing the amount of fuel flowing into cylinder in PFI gasoline engines. Reduction of wall film can reduce fuel consumption and improve combustion stability. In this research, the effects of injection strategies including injection pressure and dual injection system is investigated for reducing wall film formation. The CONVERGE software is used for numerical analysis tool and O'Rourke film splash model was used for wall film prediction model. Compared with the reference case wall film decreased with increase of injection pressures, and the film formation reduced when the dual injection system was used.

This paper describes a MEMS-based micro-fluxgate magnetic sensing element using Ni$\_$0.8/Fe$\_$0.2/ film formed by electroplating. The micro-fluxgate magnetic sensor composed of a thin film magnetic core and micro-structured solenoids for the pick-up and the excitation coils, is developed by using MEMS technologies in order to take advantage of low-cost, small size and lower power consumption in the fabrication. A copper with 20um width and 3um thickness is electroplated on Cr(300${\AA}$)/Au(1500${\AA}$) films for the pick-up(42turn) and the excitation(24turn) coils. In order to improve the sensitivity of the sensing element, we designed the magnetic core into a rectangular-ring shape to reduce the magnetic flux leakage. An electroplated permalloy film with the thickness of 3 $\mu\textrm{m}$ is obtained under 2000Gauss to induce magnetic anisotropy. The magnetic core has the high DC effective permeability of ∼1,100 and coercive field of -0.1Oe. The fabricated sensing element using rectangular-ring shaped magnetic film has the sensitivity of about 150V/T at the excitation frequency of 2MHz and the excitation voltage of 4.4Vp-p. The power consumption is estimated to be 50mW.

In order to clarify the final process of oil consumption, the distribution and flow of oil through each ring were visualized by induced fluorescence method. Motoring and firing test were performed in a single cylinder research engine with transparent cylinder liner. The appropriate calibration techniques were used to solve the unstability of induced light intensity as well as to know the relation of the oil film thickness and output signal. Oil behavior was also observed at dynamic state by high speed CCD camera. By analyzing the oil film thickness converted from the photographed image, it was observed that the main route of oil transport through each ring is the end gap under the usual operating condition, low engine speed and low load condition. Oil film thickness is observed to be irregular and tend to move in a body horizontally at a given piston land. And it is also found that oil flows through oil ring gap so quickly that it can be observed in a single cycle, but it flows so slowly through top and 2nd compression rings that it takes quite a long time to detect the flow.
