Smartphones are representative multimedia devices capable of various functions that have emerged due to the development of information communication technologies (ICTs). The popularization of smartphones has changed the way ICTs media is used; consequnetly, it is expected that smartphones will influence family life by changing family communications and time use. However, there is a gap between the empirical research on ICTs media and family. This study explores any correlations in the amount of time spent on smartphones between a husband and wife. We marged 1,444 married couples' media diaries from the 8th Korean Media Panel Survey (2017) to analyze the average amount of time spent on communications and leisure shopping using smartphones. The results show that husbands' time use for communication has increased similarly to wives' time use. In addition, husbands' time use for leisure and shopping was positively related to wives' time spent on communications and leisure shopping. The findings show that the use of smartphones is interrelated within the family and suggested that a family systems approach is needed in ICTs media research. Future studies will provide a deeper understanding of the impact of ICTs media and how families are using a variety of ICTs media devices such as smartphones.

Candidate images refer to a holistic impression of a candidate which is composed of various dimensions of attributes. This study investigated how online and offline news media, campaign media such as political ads, televised debates, and candidate web-sites, and interpersonal political talk influenced voters' images of a candidate in such dimensions as personal traits, job-performance abilities, and policy capabilities, and further their political decision making in the 17th presidential election in Korea. The analysis focused on President Lee, Myung Bak who won the election by obtaining nearly 50% of the effective votes. According to the data analyses, first, uses of offline newspapers positively influenced voters' images of candidate Lee's personal traits such as his morality, integrity, trustworthiness, and compassion, yet online news uses had an opposite effect on voters' impression of his job-performance and economic policy capabilities. Secondly, among various campaign media, television ads and candidate web-sites positively contributed to the formation of candidate Lee's images, yet showed little direct effect on vote choice, indicating that campaign media mainly indirectly influenced voters' political decision making. Each of the first, second, and third televised candidate debates revealed unique effects on image formation and vote choice. Thirdly, the network size and frequency of political talk negatively influenced image formation regarding candidate Lee's personal traits and economic policy capabilities, yet the discussion network size positively contributed to the Lee votes. Forth, among various dimensions of candidate images, voters' perceptions of candidate Lee's personal traits appeared to be the most significant predictor of the support for him.

With the increasing number of social media users worldwide, cases of social media being abused to perpetrate various crimes are increasing. Specifically, drug distribution through social media is emerging as a serious social problem. Using social media channels, the curiosity of teenagers regarding drugs is stimulated through clever marketing. Further, social media easily facilitates drug purchases due to the high accessibility of drug sellers and consumers. Among various social media platforms, we focused on Instagram, which is the most used social media platform by young adults aged 19 to 24 years in South Korea. We collected four types of information, including profile photos, introductions, posts in the form of images, and posts in the form of texts on Instagram; then, we analyzed the similarity among each type of collected information. The profile photos and posts in the form of image were analyzed for similarity based on the SSIM(Structural Simplicity Index Measure), while introductions and posts in the form of text were analyzed for similarity using Jaccard and Cosine similarity techniques. Through the similarity analysis, the similarity among various accounts for each collected information type was measured, and accounts with similarity above the significance level were determined as the same drug sales account. By performing logistic regression analysis on the aforementioned information types, we confirmed that except posts in image form, profile photos, introductions, and posts in the text form were valid information for tracking the same drug sales account.

The importance of church school education is becoming more emphasized. To maximize the effectiveness and efficiency of church school education, frequent utilization of instructional media is more desirable. Systematic approach to media utilization will be developed by the extabilishment of church media center. The purpose of this study was to review the concept and components of church media center and to survey the current status and hope for the facility of church media center. For the survey the 400 questionnaries were distributed to pastors or missionaries who are responssible for education, or personnels in church media center in Korea. The churches that they belong to have above approximately 500 church members. Among the distributed questionnaires, the 202 were collected. The results of the survey are as follows. The printed media and the AV media were managed separately in most churches. Many church media center was shared the space with other programs. The space was allocated mainly for storage. Most respondants hoped that they have a variety of areas in their churches. Many church media center have no separation between the area for the adults and that for children. However, most respondants hoped the separation of that areas. Followings are suggestions for the plan of church media center facilities. The space only for the church media center should be allocated. Church media center should be located in the first floor of the building as soon as possible. (If there is elevators in the building, it may be located above first floor). If enough space for the church media center is allocated, the areas for the adults and children should be separated by partitions or separate room. The space should consist of various areas like circulation area, reading area, working area for the personnel, production area, and storing area.

This paper is intended as an application of the biological rope media sedimentation tank using biodegradability of BAC(Biological activated carbon) to the drinking water treatment system for the removal of NOM. The removal of DOC(Dissolved organic carbon), UV absorbance(UV$\_$254/), and turbidity were evaluated under various operation condition of a biological rope media sedimentation tank such as raw water-media process (Media 1), ozonation-media process (Media 2), and ozonation-coagulation/sedimentation-media process (Media 3). The raw water had DOC concentration of 1.3∼3.4 mg/L, UV$\_$254/ of 0.027∼0.039 cm$\^$-1/, and turbidity of 0.3∼4.5 NTU, respectively. The average DOC concentration were 2.2 mg/L in media 1, 1.8 mg/L in media 2, and 1.3 mg/l in media 3 from raw water, respectively. On the other hand, the DOC concentration in conventional sedimentation tank was 1.5 mg/l. Higher removal of the DOC was noted in media 3 than media 1 and media 2. The UV$\_$254/ of the treated water were 0.037 cm$\^$-1/ in media 1, 0.027 cm$\^$-1/ in media 2, and 0.014 cm$\^$-1/ in media 3 from raw water, respectively The UV$\_$254/ in conventional sedimentation tank was 0.014 cm$\^$-1/ which is similar to that of media 3. Average turbidity of the treated water was 1.1 NTU in media 1, 0.9 NTU in media 2, and 0.5 NTU in media 3, respectively. It is expected that the biological rope media sedimentation tank is a good alternative over the conventional sedimentation process from these results.

When various strains of Streptomyces griseus and S. galbus were examined for the ability on the production of streptomycin in tryptic soy(TS) broth, S. griseus ATCC 27001 was found to be the best. S. griseus ATCC 12475 and ATCC 23345 showed also good growth and favorable production of streptomycin. Examination of various complex media reported in fermentation literatures for the industrial production of streptomycin indicated that glucose-soybean media-sodium chloride (GSS) broth and K (Chucken) broth gave higher yields of streptomycin than others studied by us. Examination of the ingredients of media producing streptomycin in high yield indicated that some components in soybean activated the production of streptomycin. Addition of meat extract enhanced the yield of streptomycin but it could be substituted with distillers solubles without much effect on the yield. Addition of corn steep liquor decreased the production of streptomycin.
