The quality of a food is judged by the consumer according to its appearance, taste and texture. Especially among them, color is recognized as a major factor affecting food acceptance. This study was performed in order to develop a new yanggaeng products having beautiful appearances, attractive flavors, lower calories and healthier functions. We have investigated on the quality characteristics and storage stability of sweet jelly beans(colored yanggaengs) prepared by adding with natural ingredients, such as fruit juices and green tea powder. To obtain various colors and flavors, different ingredients were used such as fruit juices made directly from cherry(red color), orange(orange color, or yellow color), grapes(dark violet color). Also green tea powder(leekgreen color) was purchased from a market. Yanggaengs were prepared by adding these fruit juices or green tea powder, which Azuki bean powder as sediment, non-calorie sugar, and agar-agar products, etc. Color, texture profile analysis, sensory evaluation, viable cell count, and the strength of sample yanggaengs were examined to assess their acceptability for commercial use. In conclusion, the new colored yanggaengs could possess better appearances, flavors and healthier functions, compared with commercial products sold in market. Additionally, they could have lower calories because sugar was not used as a sweetener.

저자들은 폐결핵 추정하에 치료를 받았던 Sarcoidosis 환자 1례를 경험했기에 문헌적 고찰과 함께 보고하는 바이다. Sarcoidosis is a granulomatous disease of unknown etiology In which pulmonary manifestations typically predominate with protean extrapulmonary and systemic manifestations. In sarcoidosis, pulmonary symptoms include dyspnea on exertion, non-productive cough and wheezing. Typical radiologic finding is a diffuse infiltration with or without bilateral symmetric hilar lymphadenopathy. Sarcoidosis should be differentiated with pulmonary tuberculosis because of its clincal and radiological slmilarity in Korea, an endemic area of pulmonary tuberculosis. We report a case of sarcoidosis patient whose symptoms were not improved by treatment with anti-tuberculous medication, but by steroid therapy following the diagnosis of sarcoidosis made by biopsy.

This paper is intended to investigate the properties of fresh and hardened concrete, in which cement and fine aggregate are replaced with cement kiln dust(CKD), for effective using method of CKD, a by-product produced in the process of making cement. According to the results, as the replacing ratio of CKD increases, slump and air content of concrete decreases remarkably due to an increase of viscosity and filling of the pores respectively. As the properties of setting, setting time are shortened with an increase of the replacing ratio of CKD. Compressive strength increases due to the filling effect of the pores in comparison with plain concrete, and compressive strength ratio is high at early age.

이규경의 저서들이 가지는 가치는 바로 이런데서 찾을 수 있는 것이다. 실제로 활용될 수 있는 학문에 대한 그의 신념과 정열은, 우리나라의 많은 장인들의 전통적 기술을 기의 완전한 망각의 일보전에서 비록 완전하지는 못하였지만, 기록 속에 담아서 보존하는데 크게 기여하였다. 그의 박물학과 실학사상은, 생산적인 기술을 재기로 보던 조선왕조시대에 지식인들이 별로 관심을 두지 않았던 자연과학과 기술에 중점을 두고 실증적인 정신에 입각하여 학문적으로 체계를 세웠다는 데서 그 근대지향적이고 전진적인 성격을 찾아볼 수 있다. 그리고 그의 학문으로서 과학·기술의 전개는 조선 후기 실학의 중용한 구성 요소로서 한국의 전통과학을 재발견하고 그 위치를 뚜렷하게 하는데 크게 공헌하였다.

An experiment was carried out to investigate the characteristics of the evaporation heat transfer and pressure drop for refrigerant R407C in a fin-and-tube heat exchanger of commercial air-conditioning unit. Test was conducted at the conditions of inlet refrigerant evaporation temperature 7℃, inlet air relative humidity of 40~50%, and refrigerant mass flux varying from 150 to 250kg/m2s. The evaporation temperature of the refrigerant at the test section inlet were maintained at 7℃. Evaporation performance of R407C was 4.6~11.7%, 2.5~15% lower than compared to that of R22 for relative humidity 40% and 50% respectively and this difference was increased as the refrigerant mass flux increases. The experimental data were also useful in analyzing the effects of the temperature glide and length of two phase region for ternary non-azeotropic refrigerant mixture R407C, which is one of the potential candidates for the replacement of pure refrigerant R22.

Primary pulmonary amyloidosis is a rare disorder. It can be classified into tracheo-bronchial, diffuse alveolar septal and nodular parenchymal form. Tracheo-bronchial amyloidosis can be further subdivided into diffuse and focal varieties. We report a case of diffuse tracheo-bronchial amyloidosis in a 49-year old man comfirmed by broncos-copic biopsy. He has suffered from cough and exertional dyspnea over 20 years and recently atelectasis of fright middle and lower lobe was found on chest X-ray with aggravation of symptom. The chest CT showed irregular thickening of tracheo-bronchial wall with calcification in addition to collapse of right middle and lower lobe. The bronchoscopy showed multiple variable sized submucosal nodules in lower trachea and both sides of bronchi, and biopsy revealed amyloid deposition at the subepithelial layer. We discussed this case with review of literature.

Wireless Multihop Device-to-Device Caching Networks

<P>We consider a wireless device-to-device network, where n nodes are uniformly distributed at random over the network area. We let each node caches M files from a library of size m >= M. Each node in the network requests a file from the library independently at random, according to a popularity distribution, and is served by other nodes having the requested file in their local cache via (possibly) multihop transmissions. Under the classical 'protocol model' of wireless networks, we characterize the optimal per-node capacity scaling law for a broad class of heavy-tailed popularity distributions, including Zipf distributions with exponent less than one. In the parameter regime of interest, i.e., m = o(nM), we show that a decentralized random caching strategy with uniform probability over the library yields the optimal per-node capacity scaling of Theta(root M/m) for heavy-tailed popularity distributions. This scaling is constant with n, thus yielding throughput scalability with the network size. Furthermore, the multihop capacity scaling can be significantly better than for the case of single-hop caching networks, for which the per-node capacity is Theta(M/m). The multihop capacity scaling law can be further improved for a Zipf distribution with exponent larger than some threshold >1, by using a decentralized random caching uniformly across a subset of most popular files in the library. Namely, ignoring a subset of less popular files (i.e., effectively reducing the size of the library) can significantly improve the throughput scaling while guaranteeing that all nodes will be served with high probability as n increases.</P>
