This study was carried out to compare the agronomic characteristics, forage yield, and feed value of nine sorghum ${\times}$ sudangrass hybrids at paddy field cultivation. The nine recommended sorghum ${\times}$ sudangrass hybrids used in this study were P877F, Cow pow, Turbo gold, Maxi graze, Jumbo, G7, Sweet home, Honey chew BMR and Green star. Plant height, leaf number, stem diameter, and stem hardness were higher in Jumbo than other varieties (P<0.01). Sugar content (brix) was higher in order of P877F > Sweet home > maxi graze > Green star > Cow pow > G7 (P<0.01). Fresh (86,199kg/ha) and dry matter yield (16,206 kg/ha) of Jumbo were higher than other varieties (P<0.01). Crude protein was the highest in Maxi graze (6.5%), but crude fat was the highest in Honey chew BMR as 2.1% (P<0.01). NDF and ADF of Jumbo and G7 were higher than other varieties (P<0.01). TDN was higher in order of Maxi graze > Sweet home > P877F > Honey chew BMR > Green star, but no significant differences were found among the varieties. Minerals were the highest in Cow pow (15,020.5 mg/kg), and Sweet home (6,222.6 mg/kg) was the lowest as compared to other varieties (P<0.01). Total amino acids were higher in order of Maxi graze > Sweet home > Turbo gold > Honey chew BMR > Jumbo (P<0.01). Crude protein yield and crude fat yield were the highest in Turbo gold (814.6 kg/ha) and Honey chew BMR (309.8kg/ha), respectively (P<0.01). Mineral yield was the highest in Cow pow as 207.6 kg/ha (P<0.01). Amino acid yield (592.2 kg/ha) and TDN yield (10,194 kg/ha) were the highest in Sweet home. Based on the above results, sorghum ${\times}$ sudangrass hybrid varieties should be selected on the basis of the purpose of use. Because, each varieties showed various growth characteristics and nutrition yield (protein, fat, mineral, amino acid, TDN).

The purpose of this study was to find anatomical variation of each small breed dog's dentition for designing more effective dental chews. Small breed dogs were volunteered for dental impressions with dental stone and alginate under tiletamine-zolazepam, tramadol, and medetomidine intravenous anesthesia. Twenty-two criteria were measured to compare dental impressions. Twenty-five dogs (9 Malteses, 8 Miniature Poodles, and 8 Shih-Tzus) were recruited. Statistically, Shih-Tzus had smaller teeth and shorter interdental spaces than those of Maltese and Miniature Poodles. Grossly, the distance between upper teeth and lower teeth was wider in Shih-Tzus. Shih-Tzu had different dental anatomy in comparative to Miniature Poodle and Maltese. It was recommended to design the dental chew considering these differences.

This study was conducted to develop easily chewable Korean rice cake (Garaedduk) for the elderly while maintaining its original form and flavor. We developed two types of easy-to-chew Garaedduk products by adding starch-degrading enzyme or trehalose, respectively. Characteristics of Garaedduk products were investigated and comparative analysis was carried out between control and experimental groups. The water content of control and enzyme-added Garaedduk was 43.55% and 44.11%, respectively, which was significantly higher than trehalose-added Garaedduk (40.30%) as free water content was reduced by the formation of hydrogen bonds between trehalose and water molecules. Due to the browning of reducing sugar produced by the decomposition of rice starch, Hunter b-value of enzyme-added Garaedduk was significantly higher compared to others. Hardness, adhesiveness, gumminess, and chewiness of experimental groups were lower than the control group. Consumer test scores showed significant differences with respect to overall liking, chewiness, and swallowing between control and experimental groups. Elderly preferred experimental Garaedduks over control and the experimental groups were evaluated to be softer, easily chewable, and swallowable.

This study was conducted to investigate the effects of species and varieties of summer forage crops on growth characteristics and productivity in Sihwa reclaimed land. The summer forage crops used in the trial were silage corn, sorghum×sudangrass hybrid(SSH), and proso millet. For each forage species, Gwangpyeongok(GPO), P15453, P1952 and P2088 were used for silage corn, and 877F, Green star, Honey chew, and Turbo gold cultivars were used for SSH. For proso millet, Ibaekchal, Geumsilchal and Manhongchal developed by the National Institute of Crop Science were used. Silage corn and SSH were sown on May 21, 2019 and proso millet on June 4, and harvested on September 2. There was no significant difference in plant and ear height of silage corn among varieties. P1543 was the highest and P2088 was the lowest in yield of silage corn, but there was no significant difference among treatments. Among the SSH, the plant height of 877F was the highest and Turbo gold variety had the smallest (p<0.05). As for the dry matter(DM) yields, 877F had the highest at 3,862 kg/ha and Green star had the lowest at 2,669 kg/ha (p<0.05). The fresh matter yield of proso millet was 15,778 kg/ha, which was higher than that of corn or SSH, The average dry matter yield was 4,780 kg/ha, and Ibaekchal variety had the highest DM yield compared to other varieties (p<0.05). P2088 had the highest TDN content and GPO was the lowest (p<0.05). As for the SSH, the TDN content of Green star and Honey chew varieties was significantly higher, and the RFV value was the lowest in Turbo gold. The average crude protein content of proso millet was 7.03%, and the highest TDN and RFV values were 64.36% and 106 in Geumsilchal. In the experiment of the germination rate of summer forage crops according to salt concentration, silage corn showed a germination rate of 83.1% even at 0.4% salinity. In particular, P2088 and P1921 varieties had more than 80% germination rate even at 0.6% salt concentration. As for the SSH, the germination rate of 877F was 93.3% even at 0.8% salinity, and 88.3% with Honey chew, indicating higher resistance to salt concentration compared to other varieties. Proso millet showed a high germination rate of 84.0 to 88.7% even at a salt concentration of 0.6%. Considering the above results, proso millet was recommended as the most suitable forage crop species in the Sihwa reclaimed land with high salt concentration, and the Ibaekchal variety is recommended as a suitable forage crop due to its high yield.

Wireless Sensor Networks(WSNs) are used in diverse applications. In general, sensor nodes that are easily deployed on specific areas have many resource constrains such as battery power, memory sizes, MCUs, RFs and so on. Hence, first of all, the efficient energy consumption is strongly required in WSNs. In terms of event states, event-driven deliverly model (i.e. surveillance and reconnaissance applications) has several characteristics. On the basis of such a model, clustering algorithms can be mostly used to manage sensor nodes' energy efficiently owing to the advantages of data aggregations. Since a specific node collects packets from its child nodes in a network topology and aggregates them into one packet to relay them once, amount of transmitted packets to a sink node can be reduced. However, most clustering algorithms have been designed without considering can be reduced. However, most clustering algorithms have been designed without considering characteristics of event-driven deliverly model, which results in some problems. In this paper, we propose enhanced clustering algorithms regarding with both targets' movement and energy efficiency in order for applications of surveillance and reconnaissance. These algorithms form some clusters to contend locally between nodes, which have already detected certain targets, by using a method which called CHEW (Cluster Head Election Window). Therefore, our proposed algorithms enable to reduce not only the cost of cluster maintenance, but also energy consumption. In conclusion, we analyze traces of the clusters' movements according to targets' locations, evaluate the traces' results and we compare our algorithms with others through simulations. Finally, we verify our algorithms use power energy efficiently.

Objective : Health literacy (HL) is, defined as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." Being old is one of the main risk factors with limited health literacy. This study aims to adapt Chew's health literacy scale into the Korean language and validate the scale for the use of the elderly. Methods : Data were drawn from the '2016 Seoul Survey on Elderly Health and Functional Assessment, which includes a total of 725 people aged 60 to 79. The sample was randomly divided into two groups for reliability and validity tests of the modified Chew's scale of 8 items. The Korean version of the questionnaire was developed by group translation, expert reviews, and forward-backward translation. Exploratory and confirmatory factor analyses were conducted to assess and validate the factor structure of the scale. Results : Results suggest the two-factor structure ("Understanding" and "Applying" of HL) with 8 items. Exploratory factor analyses of the first sample (n=400) revealed that the internal reliability of the scale was high (Cronbach's ${\alpha}=.904$). Principal axis factoring extracted two factors ("Understanding" and "Applying" of HL) and explained 78.3% of total variance (KMO=.872, Bartlett's ${\chi}^2=2431.3$, df=28, p<.001). Confirmatory factor analysis of the second sample (n=325) was performed and the two-factor model was supported (GFI=.960, CFI=.979, TLI=.969, RMSEA=0.075). Conclusions : This study provides evidence for adequate criterion and validity of the health literacy scale for the community dwelling elderly in Korea.
