디지털 컨버전스 개념이 속속 도입되고 있다. 휴대폰은 어느덧 디지털 카메라 기능과 MP3기능은 물론 DMB수신 기능을 갖춘 방송 수신기기의 역할 까지 맡고 있다. 또 최근에는 혈당 및 체지방 등 건강 관련 수치를 측정하고, TV리모콘 기능에 하드디스크 기능 까지 갖추고 있다. 콘텐츠 분야에 있어서도 마찬가지다. 이제 콘텐츠 분야에서는 유선 콘텐츠와 무선 콘텐츠의 경계가 없어지는 양상을 보인다. 유선에서 사용하는 인스턴트 메신저를 무선에서 바로 이용하고, 유선 인터넷 사용자와 함께 게임을 즐긴다. 이러면서 유무선의 경계는 점점 옅어져 간다. 이제 소비자들은 콘텐츠의 종류를 가리지 않고 그저 같은 콘텐츠로 느끼기 시작했다고도 할 수 있다.

This study examined the relationship of what kind of creative thinking has related factors for emotion design products in order to let consumers focusing on the successful cases of emotion products. For the design creativity attribute used in this experiment, the design evaluation creativity tools revealed by Kim Eun-Ju's 2007 design creativity evaluation tool development were used mostly and of the 12 most common emotion products and general product, MP3s, which have various forms, functions and sizes were selected as the target for experiment. Results of the experiment showed that for design creativeness items of all emotional products, vision creation, favorableness, convenience, practicality and being purchasable were relevant, while for MP3, uniqueness, favorableness and convenience were relevant. Accordingly, the common features of design creativeness items for emotional products were identified. When summing up the contents of the two experiments above, for emotional designs, the interest level of uniqueness for the design creativity evaluation items and the functional items for practicality had a high level of relativity. Therefore, there is a need to examine the common features between the design creativity items for general products other than MP3s in the future.

Being popularized the use of portable entertainment/information devices, the demand on flash memory has been also increased radically. In general, flash memory reveals various error patterns by the devices it is mounted, and thus the memory makers are trying to minimize error ratio in the final process through not only the electric test but also the data integrity test under the same condition as real application devices. This process is called an application-level memory test. Though currently various flash memory testing devices have been used in the production lines, most of the works related to memory test depend on the sensual abilities of human testers. In case of testing the flash memory for MP3 devices, the human testers are checking if the memory has some errors by hearing the audio played on the memory testing device. The memory testing process like this has become a bottleneck in the flash memory production line. In this paper, we propose an audio comparison technique to support the efficient flash memory test for MP3 devices. The technique proposed in this paper compares the variance change rate between the source binary file and the decoded analog signal and checks automatically if the memory errors are occurred or not.

디지털기기가 대중화하면서 소비자들의 취향이 까다로워지고 있다. 이전의 독립적인 제품이나 서비스들의 고유 기능만 구입하던 소비자들이 이제는 한가지 기능만을 고려하지 않는 추세다. 이로 인해 관련 업계는 다양한 기능을 하나로 집적하는 디지털 컨버전스화에 골몰하고 있다. 부품 성능향상, 가격하락 및 압축기술의 발전으로 컴퓨터.통신기기.가전제품 등 디지털 기기의 컨버전스화가 가속화되면서 문자.화상.소리.영상 등을 하나의 기기로 해결하는 융복합 현상은 업계의 차별화 전략이자 중요한 승부수가 될 전망이다.

In digital multimedia society, we usually use the digital sound music ( Mp3, wav, etc.) system instead of analog music. In the middle of generating or recording and transmitting, if we embed the digital code which is useful to music information, we can easily select as well as classify the music title by using Mp3 player that embedded sound source classification system. In this paper, sound source classification system which could be classify and search a music informations by way of user friendly scheme is implemented. We performed some experiments to testify the validity of proposed scheme by using implemented system.

The characteristics of sponge cakes prepared with replacement of 30, 50, 75, or 100% of sucrose with isomaltooligosaccharide (IOS), fructooligosanharide (FOS), maltitol symp (MS), or maltitol powder (MP), were examined through physical measurement and sensory evaluation. The specific gravities of foams and cake batters were not significantly different among samples (p .0.05). The use of IOS increased the viscosity of cake batter. The cakes containing IOS, FOS, MS, or MP were softer than control cakes (sucrose 100%). Especially cakes prepared with 30, 50％ IOS, or 75, 100％ MP, appeared to be fragile. When increasing levels of IOS or FOS were incorporated in the cake formula, cake crust color was getting darker than that of control cake, whereas cake containing maltitol was getting lighter as the levels of replacement increased. Generally, the volume of cake containing FOS were superior to that of control cake, whereas those of cakes containing above 50% MP were inferior. Sensory analysis of experimental cakes did not show significant differences from the control cake for softness, springiness and gumminess. Sweetness increased replacing the sucrose with FOS, MS or MP (30, 50%) and moistness increased using IOS, FOS, MS, or MP without agreement with moisture contents of cakes. Replacement of 30, 50% sucrose with MS or 30％ with MP did not affect greatly the physical measurements or sensory characteristics studied.

In previous work, we fermented coffee beans using solid-state culture with various fungal mycelia to enhance the physiological activity of the coffee. The coffee fermented with Monascus sp. showed a higher physiological activity than non-fermented coffee or other coffees fermented with mushroom mycelium. The aim of this study was to characterize the various fermented coffees with respect to their area of cultivation and their variety using Monascus purpureus (MP) mycelium solid-state culture. Thirty types of green coffee beans, which varied in terms of their cultivation area or variety, were purchased from different suppliers and fermented with MP under optimal conditions. Each MP-fermented coffee was medium roasted and extracted further using hot water (HW) under the same conditions. Of the HW extracts, those derived from MP-Mandheling coffees had the highest yield (13.6-15.5%), and MP-Robusta coffee showed a significantly higher polyphenolic content (3.03 mg gallic acid equivalent/100 mg) and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) free radical scavenging activity (27.11 mg ascorbic acid equivalent antioxidant capacity/100 mg). Furthermore, in comparison to other MP-fermented coffees at $1,000{\mu}g/mL$, MP-Robusta coffee showed not only the most effective inhibition of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) production in LPS-stimulated RAW 264.7 cells (67.1% of that in LPS-stimulated control cells), but also an effective inhibition of lipogenesis in 3T3-L1 adipose cells (22.2% of that in differentiated control cells). In conclusion, these results suggest that Vietnam Robusta coffee beans solid-state fermented with MP mycelium are amenable to industrial applications as a functional coffee beverage or material.

흔히‘20:80 이론’을 말한다. 이탈리아의 경제학자 빌프레도 파레토가 주창했다는 이 이론은 원래는 19세기 영국의 부(富)의 불균형을 말할 때 20%의 인구가 80%의 부를 차지한다는 것에서 나왔던 것이지만, 비단 이것뿐만 아니라 현재 주위에 있는 대부분의 것에 적용을 해봐도 통용될 수 있는 이론이라 할 수 있다‘. 20%의 기능이 80%의 쓰임으로 활용된다.’휴대폰을 늘 끼고 살면서도, 가뜩이나 컨퍼전스 개념이 도입돼서 온갖 기능으로 중무장한 휴대폰일 지라도, 그 중 몇몇 기능에 불과한 통화 기능, 문자메시지 수,발신 기능, 모닝콜 기능, 달력 기 능, 디지털 카메라 기능과 MP3 기능, 종종 VM 콘텐츠를 활용한 게임 기능 등을 제외하고는 그다지 많이 활용하고 있는 것 같지는 않다(물 론 가장 중요한 시계 기능도 있다). 그게 전부일까? 우리가 아는 이동통신의 전부일까? 이번 호에서는 우리가 미처 알지 못해서 사용하지 못 하고 있는 이동통신사 자체의 부가서비스에 대해서 알아보려 한다. 또 사업자를 위한 제안 요령에 대해서도 설명할 계획이다. 모름지기 아는 만큼 활용할 수 있다.

The study classifies online game users with two groups, which are users who purchase functional items and emotional items. This research used statistic tool, STATA MP, trying unpaired t-test to find relationships between two groups on payment intention and characteristics. The result shows that the users with functional items prefer community-oriented mind and interaction with other users while users with emotional items intend to consider item's design and superiority with higher purchasing satisfaction. The result of this study seems to give some implications to game companies when improving its purchasing system with charged items.
