공공도서관에서 제공하는 향토정보서비스는 낮은 이용률을 나타내고 있으며, 대부분 열람 및 대출형태의 제한적인 서비스를 제공한다. 본 연구는 이러한 문제점을 해결하고 이용자의 정보 요구를 반영하는 새로운 향토정보서비스를 제안하고자, 모바일 어플리케이션 (이하 앱)인 LibPass (Library와 Pass의 합성어)를 개발하였다. LibPass는 향토자원의 특성들이 LibPass의 콘텐츠로 구성되어 이용자가 모바일 앱을 통해 지역의 문화관광자원에 대한 정보탐색을 한 곳에서 간편하게 할 수 있도록 설계되었다. 즉, 관광자원에 대한 소개는 물론이고, 그 이용을 위한 숙박시설, 체험프로그램, 그리고 특화도서관에 대한 정보를 제공함으로써, 향토자원에 대한 효율적인 정보서비스를 도모하고자 했다. 무엇보다도 이 서비스는 국립중앙도서관에서 발행하는 카드로 일원화되어 제공되므로 전국 어디서나 사용이 편리하고, 공공기관의 다양한 콘텐츠를 활용하여 신뢰성과 최신성을 확보하였다. 선행연구를 바탕으로 모바일 관광정보서비스의 품질 평가 요인들을 도출하였으며, 또한 기존의 관광정보서비스 앱을 분석하여 LibPass 앱의 개체들을 구성하고 논리적 개체 관계 모델을 기반으로 프로토타입을 개발하였다. 이 모델은 도서관의 향토정보서비스 이용률을 증가시키고, 더 나아가 이용자 친화적인 앱을 통해 도서관에 대한 긍정적인 인식을 높이는 데 기여할 수 있다.

The current study investigated the relative effects of viewing motivations on viewing preferences and viewing intentions of television food programs. Data collection was conducted by administering a survey to television food program viewers both on and offline. Viewing motivations were categorized as 'information' 'entertainment', 'pass-time', 'companionship', 'relaxation', and 'social interaction'. 'Information' and 'entertainment' proved to be the most important motivational factors affecting viewing preferences for television food programs. 'Information' and 'social interactions' were the strongest predictors of viewing intentions of television food programs. However, 'pass-time' had a negative influence on both viewing preferences and viewing intentions of television food programs. Furthermore, the results of study verified the moderating effects of food involvement in these relations.

Urological cancers such as kidney, bladder, prostate, and testicular cancers are the most common types of cancers worldwide with high mortality and morbidity. To date, traditional cell lines and animal models have been broadly used to study pre-clinical applications and underlying molecular mechanisms of urological cancers. However, they cannot reflect biological phenotypes of real tissues and clinical diversities of urological cancers in vitro system. In vitro models cannot be utilized to reflect the tumor microenvironment or heterogeneity. Cancer organoids in three-dimensional culture have emerged as a promising platform for simulating tumor microenvironment and revealing heterogeneity. In this review, we summarize recent advances in prostate and kidney cancer organoids regarding culture conditions, advantages, and applications of these cancer organoids.

The implementation of a hybrid network utilizing Power Line Communication (PLC) and Wi-Fi technologies has been demonstrated to improve signal strength and coverage in areas with poor connectivity due to internet shadow areas. In this study we strategically positioned Wi-Fi relays and utilized the capabilities of PLC technology to significantly improve signal strength and coverage in areas with poor connectivity. We also analyzed the effects of metallic obstacles on Wi-Fi signal propagation and proposed a solution to strengthen the signal enough to pass through them. Our experiment demonstrated the feasibility and potential of using this hybrid network in industrial scenarios for real-time data transmission. Overall, the results suggest that the use of PLC and Wi-Fi hybrid networks can be a cost-effective and efficient solution for overcoming internet connectivity challenges and has the potential to provide high-speed internet access to areas with unreliable signals.

From 1998 Seoul city is being rebuilt for 'the city which people want to go around on foot'. Many streets only for cars have been transformed for pedestrians. In addition to that streets are built not only just to pass by, but also enjoy themselves, so 8 Streets in Seoul have been redecorated as 'Streets of History and Culture'. These Streets are chosen because they have their own unique history or culture, so they are remodeled with lightings, exhibition pavilions or sign postings etc except manhole covers. Even these 8 streets have manhole covers; they are not particular, just same as like other streets. For most streets manhole cover is an essential component of them, but it is mostly omitted to be designed in particular. For the most time some of the standard manhole covers are installed in a street. Taking a look at manholes in Minneapolis city, they inform visitors what the landmark, landscape, symbol, representative flower or tree of the city is. Sometimes they are designed by famous artists and become art which all pedestrian can enjoy. If manhole covers in 'the streets of history and culture' are designed to represent its history or culture, visitors will get information about there easily and enjoy their design. To foster manhole cover designs, the government office should co-work with professional designers or design societies and encourage people to spend a certain amount of the construction cost to design manhole covers. At school designing manhole cover can be handled in an art class and besides can have a class in the field, streets to observe manhole cover designs. Getting more concern of manhole cover design, competitions and exhibitions are able to be held.

A primary culture of human fetal hepatocytes was obtained through a therapeutic abortion process at 26 weeks of gestation period. More than $10^8$ cells were seeded on a plastic plate. These hepatocytes were infected with hepatitis B virus (HBV). The HBV was purified from serum of one chronic HBV carrier. Transformed hepatocytes were subcultured in a 10% FBS-supplemented medium. The morphology of the transformed cell was epithelial-like. The cells from the first pass showed signs of early proliferation and had a latent period of more than 3 months after 6-7 passages. After the rest period, the transformed cell proliferated actively and they were subcultured every three days. Transformed hepatocytes were characterized by detection of the HBV transcript by RT-PCR. The secretion of virions from transformed cells was investigated by PCR with the cell medium. Two types of virions secreted into the culture medium were examined by using the transmission electron microscope. Another approach to study the secretion of virions in to culture medium was carried out with HBV antibody. HBsAg was detected in the culture medium of transformed cells using ELISA and Western blot analyses. These data suggested that the human fetal hepatocyte cell line has been established by infection of HBV, in which this cell line secreted viral particles into the culture medium.

This experiment examined the effects of feeding Aspergillus oryzae (AO) culture to laying hens, on fecal microbial populations, fecal pH and moisture content, egg quality, and metabolizabilities of several nutrients. Sixteen commercial 38-wk-old laying hens were randomly allotted to four diets: control; with 0.15% locally produced AO culture; with 0.3% locally produced AO culture, and; or with 0.3% imported AO. Each treatment consisted of four replicates (cages) containing one bird per cage according to a completely randomized design. After 4 wk, AO were recovered in the feces of birds fed the AO diets, indicating that AO might pass through the fore-gut alive and become active in the hind gut. The number of Lactobacillus spp. in feces was higher in all treated groups than that of the control, indicating that AO would provide a beneficial environment for the Lactobacillus spp. to proliferate in the intestine. The number of fecal E. coli was significantly reduced by the addition of AO. A similar trend was also found for aerobic bacteria. Although not significant, fecal moisture contents tended to be reduced by the addition of AO. Fecal pH was not significantly different among the treatments. The addition of AO did not affect the various economic traits of eggs. Metabolizabilities of gross energy and dry matter measured during the 5th wk were increased by the AO supplementation. It appears that AO culture alone could be used as a probiotic supplement for layers.
