극장 중심의 영화산업에서는 소비의 집중 현상이 발생해 영화 소비의 다양성을 저해하는 것으로 알려져 있다. 본 연구는 극장의 영화 소비 집중에 관한 기존의 논의를 온라인 영화 소비의 집중까지 확장한다. 그리고 코로나19 유행의 영화 소비와 소비집중도에 대한 영향을 분석한다. 분석을 위해 영화진흥위원회의 박스오피스 자료를 활용 2012년에서 2021년까지의 패널 데이터를 수집했다. 분석 결과 극장에서 온라인에서보다 영화별, 국가별, 장르별 소비집중도가 높은 것으로 나타났다. 그리고 코로나19 유행 이전까지 극장과 온라인 모두 영화 소비집중도가 상승한 것으로 나타났다. 코로나19 유행 기간에는 극장과 온라인의 소비 규모가 동반 감소하고, 온라인의 영화별 소비집중도는 높아졌다. 연구 결과는 영화 소비의 다양성 확보를 통한 영화산업의 장기적 발전을 위해, 소비 집중 추세의 전환을 위한 정책적 노력이 필요함을 시사하며, 이때 온라인 매체의 활용이 유용할 것을 시사한다.

Using the diet rice bowl, this study examined whether visual cues related to portion size can influence intake volume without altering satiation. 24 subjects ate lunch and subsequent dinner meal in the lab once a week for 2 weeks. Each week at noon, they were served one of two different sizes of a rice (150 g of rice by the diet rice bowl and 210 g of rice by the general rice bowl) but recognized the same volume of which they could eat as much as they wanted of side dishes. Subjects returned to the lab five hours later for a standard dinner, which was consumed ad libitum. Results showed that the subjects who were eating from the diet rice bowl ate less rice (222.4 Kcal vs 306.5 Kcal, p < 0.001) and total energy intake (412.5 Kcal vs 499.2 Kcal, p < 0.001) than those eating from a general rice bowl at lunch. However, despite consuming 21% less energy intake at lunch, the rates of satiety were not significantly different after eating from the diet rice bowl and from the general diet bowl. And there were no significant difference in rice intake and energy intake at dinner between the diet rice bowl and the general rice bowl. These results suggest decreasing the portion size by the diet rice bowl with biased visual cues leads to decreased rice intake and energy intake without altering the satiation. This is, the decreased amount of rice in a diet rice bowl may implicitly suggest what might be construed as an appropriate amount to consume and eventually it suggests smaller consumption norms.

본 연구는 유동성제약과 가구별 특성을 고려한 가구소비함수의 추정을 목적으로 한다. 우리나라의 횡단면 자료인 "가구소비실태조사"를 이용하여 분석한 결과 가구원수, 가구 내 취업자 및 취학 아동수, 가구주의 교육수준 및 연령 등으로 표현되는 가구별 특성이 소비결정에 유의하게 작용함을 알 수 있다. 특히, 가구원수가 소비결정에 미치는 영향이 지대한 것으로 나타났는데, 이는 가구원수가 가구소득의 생애주기와 관련되어 있을 뿐 아니라 소비규모를 결정함에 있어서도 직접적인 영향을 미치기 때문인 것으로 보인다. 반면 가구원수 이외의 가구특성 변수들은 소비결정에 직접적으로 작용하기보다는 소득의 변화를 통해 간접적으로(하지만 여전히 유의하게) 소비에 영향을 미친다. 또한 본 연구에서는 유동성제약의 존재 유무를 판별하는 기존의 연구와는 달리 유동성제약의 강도를 파악하는 데 초점을 맞춤으로써 소비함수 추정식의 설명력을 획기적으로 높일 수 있었다. 유동성제약의 강도는 인적자본의 현재가치를 가구별 특성의 함수로 상정한 후 그 가치가 자본시장에서 과소평가되는 정도를 살펴봄으로써 측정된다. 이렇듯 유동성제약의 강도를 구분하는 추정방식은 현실에 존재하는 여러 형태의 자산들을 유동성을 기준으로 하여 세분할 수 있도록 도와준다. 끝으로 본 연구에서는 사용된 소비함수 추정식을 이용하여 외환위기 이후 우리나라 유동성제약의 완화 경향을 확인하고 이에 따른 소비불평등도의 감소를 횡단면 분산분해방식을 이용하여 같은 기간의 소득불평등도 증가 및 가구특성 변화 현상과 분리하여 논의한다.

The objectives of the study were to determine 1) energy uses for residential requirements, 2) if energy consumption and adoption of energy conservation attitudes and practices vary with independent variables family size, stage of family life cycle, homemaker's level of education, income, heating system, and number of electrical household items, and 3) if there is a correlation between energy conservation attitudes and practices. Questionnaires were given to the randomly selected homemakers I Seoul in the summer (September, 1979) and the winter (February, 1980). Analysis of variance and correlation were used to analyzed the data which consisted of 537 usable responses of 895 returned in the summer and 554 responses of 794 returned in the winter. The results are as follows: 1) The order of consumption rate of the direct energy uses for residential requirements was found to be heating and air conditioning, cooking, refrigeration, T.V., lighting, and miscellaneous. 2) Energy consumption and adoption of energy conservation attitudes and practices were significantly related to family size, homemaker's level of education, and the stage of family life cycle. (1) Families of five members revealed higher scores in attitudes and practices than families less than five or more than six. (2) The higher the homemaker's level of education, the more energy consumption and the higher scores I attitudes and practices were found. (3) Families in the middle stage of family life cycle tend to use more energy than younger or older families, but their scores in attitudes and practices were high. 3) There was a significant correlation between energy conservation attitudes and practices. However, the scores of the conservation practices were not as good as the attitudes. It may be attributed to either a lack of knowledge and/or financial difficulties, or a dissonance between the concept and implementation of energy conservation. 4) Recommendations for the energy-saving and energy-related public policies are: (1) to use such human resources as attitudes, values, feelings of agreement, and cooperation, as well as nonhuman resources for the energy conservation, (2) to develop a educational program and a creative system I order to implement energy conservation programs, and (3) to consider direct as well as indirect energy uses I selecting goods and services.

난독처리(obfuscation)는 프로그램의 의미를 그대로 유지하면서, 프로그램 코드를 이해/분석하기 어렵게 만드는 기술로, 악의적인 역공학(reverse engineering) 공격으로부터 소프트웨어를 방어하는 가장 효과적인 기술 중의 하나이다. 하지만, 난독처리로 인해 원본 프로그램에 비해 난독처리된 프로그램의 코드 크기 및 실행 시간이 증가될 수 있다. 모바일 기기에서 코드크기 및 수행시간 증가는 전력소모 증가 등 자원낭비로 이어진다. 본 논문에서는 ARM 프로세서가 장착된 임베디드 보드 상에서 몇 가지 고급수준 난독처리 알고리즘을 구현하고, 각 난독처리 알고리즘의 유효성 및 전력 소모량을 분석하여, 프로그램의 특성에 따라 실행시간이나 전력소모 면에서 효율적인 난독처리 기법이 있음을 보였다.

The objective of this research was to estimate the size of consumption market for inland water fishes. Volumes and expenditures of a total of sixteen fishes consumed in 2007 were estimated based on a module developed. Data were collected through sample surveys of 3,081 households and 291 restaurants dealing with inland water fishes. On the basis of the results, people consumed an estimated 39.5 thousand ton as a whole on inland water fishes. An average person consumed 5.961 times and 1.136kg per year. An annual expenditure of 1,609.7 billion won was estimated. The total was divided 1,450.1 billion won on fishes(90%) and 1,595 billion won on shellfishes(10%). A typical consumer spent 41,668 won on fishes and 4,584 won on shellfishes, averaging about 46,300 won overall. Water eel was top in volumes and expenditure, while mudfish in consumption frequency.

Generally block imbedded type oil pump is adopted to make a small engine. In this paper 1D/3D numerical simulations were conducted to reduce energy consumption of the block imbedded type oil pump. At each stage of engine development we have estimated the oil flow rate and pressure to optimize oil pump sizes by using the 1D system analysis and then accomplished 3D CFD(Computational Fluid Dynamics) simulations to optimize oil pump shapes including inlet/outlet port. As a result, the energy consumption of oil pump has been reduced to nearly 27% and the engine fuel consumption to $1{\sim}1.5%$.

Test scheduling of SoC becomes more important because it is one of the prime methods to minimize the testing time under limited power consumption of SoCs. In this paper, a heuristic algorithm, in which test resources are selected for groups and arranged based on the size of product of power dissipation and test time together with total power consumption in core-based SoCs is proposed. We select test resource groups which has maximum power consumption but does not exceed the constrained power consumption and make the testing time slot of resources in the test resource group to be aligned at the initial position to minimize the idle test time of test resources.

The study investigated consumption patterns and inclination of consumers of Hanwoo meat being more expensive than imported meat and/or beef cattle meat based on the author's business experience at the shop in Budang Seongnam. The author who has managed shop firstly investigated customers' inclination and/or propensity. The author heard specific customer's story at neighboring shopping center, and each customer's buying method, occupation, financial power and apartment size and others, and forecast visiting customer's buying and demand upon part of the beef that customer asks for. The aut hor who sold out limited scope of beef product at limited area thought that he did narrow scope of business. The author would make effort to sell product enough to meet customer's taste by better quality product from point of view of customers. The author would make effort to supply good quality beef products to the customers who relied upon the author's butcher's.
