새로운 기술의 발달은 온라인 환경과 같은 새로운 시대를 열었다. 소비자들은 디지털 환경하에서 더 많은 정보력과 관계망을 갖게 되었고 디지털콘텐츠를 주도적으로 사용하고 있다. 본 연구에서는 소비자들의 디지털 콘텐츠 사용행동을 살펴보고자 하였다. 본 연구에서는 이를 위해 두 개의 연구를 진행하였다. 디지털 콘텐츠 사용 경험이 있는 소비자를 대상으로 첫 번째 연구에서는 현상학적 방법론을 활용하여 디지털콘텐츠의 불법적 사용에 영향을 미치는 제품특성을 소비자 관점에서 파악하고자 하였으며 두 번째 연구에서는 파악한 요인들을 이용하여 200여명의 서베이를 통한 정량조사로서 요인들간의 관계를 파악하고자 하였다. 이와 같은 연구결과를 바탕으로 기업은 소비자들의 디지털콘텐츠 소비 행동을 이해할 필요가 있음을 밝히고 이를 활용 적절한 마케팅 전략을 구사할 수 있는 실무적 시사점을 제시하였으며 더불어 향후 연구 방향을 논의하였다.

모바일콘텐츠는 무선 단말기에서 서비스되는 모든 콘텐츠를 의미하고 크게 커뮤니케이션, 인포메이션, 엔터테인먼트의 3가지 유형으로 나누어볼 수 있다. 이러한 다양한 유형의 모바일콘텐츠들은 각각의 특성들이 있기 때문에 콘텐츠 유형에 따라 서비스 성공을 위한 영향요인들은 차이가 있을 것이다. 본 논문에서는 모바일 콘텐츠 서비스의 성공에 영향을 미치는 주요 요인들을 도출하고 서비스 유형별로 각 영향요인들은 어떠한 차이가 있는지를 분석해 본다. 또한, 영향요인들의 영향력과 사용자의 인식도를 비교 분석하여 유의한 시사점을 도출한다.

In order to investigate the effect of magnesia clinker on the characteristics of the investments, temperature change during setting, setting time, compressive strength and thermal expansion of the investments were measured, and x-ray analyses were also performed. The investments were prepared in accordance with variation of the content and the particle size of magnesia clinker respectively. From this experiment, the results were summarized as follows; 1. Temperature of the investments during setting rapidly increased with increase of MgO contents and decrease of the particle size of magnesia clinker. 2. Setting time decreased with increase of MgO contents and decrease of the particle size of magnesia clinker. 3. Compressive strength increased with increase of MgO contents and decrease of the particle size of magnesia clinker. 4. Thermal expansion decreased with increase of MgO contents and decrease of the particle size of magnesia clinker. From the above results, the investment which contains 8% of MgO (270-325mesh) could be recommended for phosphate investment castings.

The goal of Ambient Intelligence (AmI) is to build a smart environment for users where they are supported in some of their activities by many interaction mechanisms. The diversity of AmI characteristics requires special support from Operating Systems (OSes). In this paper, in order to support a conscious choice of an operating system for any specific AmI application, features requested by AmI systems were characterized and defined considering various applications. Then, characteristics of existing Operating Systems have been investigated in the context of AmI application support to relate their key characteristics to the typical requirements of AmI systems. Qualitative mapping table between AmI characteristics and as features has been proposed with an illustration of how to use it. As no as completely covers the range of characteristics required by AmI systems, challenging issues are summarized for the development of a new as and a product line of OSes.

Laboratory experiments were conducted to examine the behavior of metalaxyl in environment which was used as pesticide in green soil of golf course and as functions of the characteristics of adsorption, desorption and degradation in soil texture and organic matter contents. Acid water containing metalaxyl was conducted to evaluate the effects on adsorption, desorption and degradation. The adsorption of metalaxyl played more significant role in organic contents than clay contents, and pH Increases more pH 2.5 than pH 5.6. The desorption of metalaxyl from contaminants soil decreased higher organic contents LS-soil than S-soil, but the desorption amount of metalaxyl increased more pH 5.6 than pH 2.5. The rate of degradation of metalaxyl in green soil environmental increased higher organic contents LS-soil than S-soil and decreased more pH 2.5 than pH 5.6. These results indicated that the behavior of metalaxyl of the green soil was affected the soil texture of the golf course. Increasing of organic contents, the adsorption amount of metalaxyl on soil increased. Moreover the decrease of the pH of solution increased adsorption amounts and decreased desorption amounts. As the results, the transportation of metalaxyl in soil decreased the acidic rates. The acidification of soil by the acid rain increased the adsorption amount of metalaxyl, but the degradation of metalaxyl decreased. Therefore, it is possible to sustain contamination in run-off the stream and ground water by residuals in soil.

This study analyzes the influence factors of IPTV users on the purchase of paid contents. This study carries out a web-log analysis of the actual users of the service provided by the domestic IPTV providers and classifies the influence factors on the purchase of paid contents largely into VOC, switching barriers, and content consumption pattern to conduct an empirical analysis. As analysis procedure, first, this study analyzes the preceding researches related to the core influence factors and content-purchasing patterns, and second, conducts a basic statistics analysis of the distribution of basic characteristics of the logs used, as presented in the above. Third, this study carries out a multiple regression analysis as an estimating equation of the number of purchasing the paid content depending on switching barriers of IPTV service, VOC, and content consumption pattern. As a statistical package, Stata version 11.2 was used. Through the empirical analysis, this study found that of the service use logs, VOC and content consumption pattern had a multi-dimensional impact on the purchase of premium contents. On the other hand, this study also found that the impact of switching barriers such as combination state with other products and current status of holding a point did not have a significant impact on the purchase of paid contents.

Gasification and melting method is one of the most potential means for waste treatment process with low emission of fly ash or heavy metal, dioxin and high possibility of using slags as resources. Moisture contents influences directly a gasification characteristics of waste. So it is necessary to investigate the effect of moisture contents in gasification. But it is hard to consider the effect of moisture contents, using samples of powder form of Milligram's order in existing thermogravimetric analyser. Therefore, we made a thermogravimetric analysis device to applicate samples of Gram's order. Gasification characteristics are typically reported with result from thermogravimetric analysis date for wood and RDF samples along with changing moisture contents. It is discussed the way to apply these analysis results to gasification and melting furnace.

Water is an essential ingredient to brew coffee. Mineral contents in the water can affect both water quality and taste quality of coffee. The effects of minerals in the water on sensory characteristics of coffee were investigated in different water samples (A: Arisu, B: Claris, C: Spring water, D: Samdasoo, E: Evian, Distilled water as control). Based on the results of quantitative descriptive analysis (QDA), there were statistically significant (p<0.01) in flavor, acidity, bitterness, sweetness, body and aftertaste according to different water samples used to brew coffee. The canonical correlation analysis of minerals (Ca, Mg, Na, K) and taste (acidity, bitterness, sweetness) indicated that there were highly correlated in the relationship between bitterness and Mg content. A strong negative relationship was shown between bitterness and acidity, sweetness. A result of preference test using hedonic scale showed an inverse linear relationship between taste quality and total mineral contents.

In this study, an experiment was performed to analyze the influence of water-cement ratio on the fundamental characteristics of antiwashout underwater concrete using blended sand (sea sand:river sand = 1:1). The water-cement ratio (45%, 50%, 55%, 60%), andtiwashout underwater agent contents (0.82%, 1.00%, 1.14% of water contents per unit volume of concrete), and superplasticizer contents (1.5%, 2.0%, 2.5% of cement contents per unit volume of concrete) were chosen as the experimental parameters. The experimental results show that the underwater segregation resistance, unit weight of hardening concrete and compressive strength were increased as the water-cement ratio decreased and as the antiwashout underwater agent contents increased. On the other hand, the flowability(slump flow) was increased to the 55% of the increase of water-cement ratio, however, it was decreased at the ratio of 60%. From this study, the antiwashout underwater concrete can potentially be used as a materials underwater work of ocean if the water-cement ratio and chemical admixture contents for the suitable balance between cost and performance are properly selected.
