Recently, demographic studies of veterinary medical database have been conducted to understand patterns of disease occurrence. Understanding incidence of breed-related disease would provide appropriate guidance for future health care strategies and offer useful information for early diagnosis of disease. However, in veterinary medicine, theses research has not yet been investigated in the Republic of Korea. The purpose of this study was to investigate the prevalence of common medical disorders among dog breeds examined at primary-care veterinary clinics in Jeollabuk-Do, Republic of Korea. The data were analyzed based on World Health Organization's International Classification of Disease. A total 13,176 medical records of canine patients were analyzed from six primary veterinary clinics in Jeollabuk-Do from January to December 2016. Results showed that the most common health problems were 'disease of skin' (17.7%); followed by 'diseases of digestive system' (12.26%), 'preventive medicine' (10.08%), and 'diseases of ear and mastoid process' (10.4%). In seven out of ten breeds, the most common medical disorder was skin disease. For poodle such as Pomeranian and Chihuahua, digestive system disease was most prevalent. On the other hand, respiratory system disease was found to be higher in Pomeranian than other breeds; while ear and mastoid process disease was most common for Maltese and Poodle. This study can help owners, breeders, and veterinarians prevent and manage various diseases of popular breeds in Jeollabuk-Do in the future.

Over the past 100 years, the global average temperature has risen by 0.75 ℃. The Korean Peninsula has risen by 1.8 ℃, more than twice the global average. According to the RCP 8.5 scenario, the CO₂ concentration in 2100 will be 940 ppm, about twice as high as current. The National Institute of Crop Science(NICS) is using the SPAR (Soil-Plant Atmosphere Research) facility that can precisely control the environment, such as temperature, humidity, and CO₂. A Python-based colony photosynthesis algorithm has been developed, and the carbon and nitrogen absorption rate of rice is evaluated by setting climate change conditions. In this experiment, Oryza Sativa cv. Shindongjin were planted at the SPAR facility on June 10 and cultivated according to the standard cultivation method. The temperature and CO₂ settings are high temperature and high CO₂ (current temperature+4.7℃ temperature+4.7℃·CO₂ 800ppm), high temperature single condition (current temperature+4.7℃·CO₂ 400ppm) according to the RCP8.5 scenario, Current climate is set as (current temperature·CO₂400ppm). For colony photosynthesis measurement, a LI-820 CO₂ sensor was installed in each chamber for setting the CO₂ concentration and for measuring photosynthesis, respectively. The colony photosynthetic rate in the booting stage was greatest in a high temperature and CO₂ environment, and the higher the nitrogen fertilization level, the higher the colony photosynthetic rate tends to be. The amount of photosynthesis tended to decrease under high temperature. In the high temperature and high CO₂ environment, seed yields, the number of an ear, and 1000 seed weights tended to decrease compared to the current climate. The number of an ear also decreased under the high temperature. But yield tended to increase a little bit under the high temperature and high CO₂ condition than under the high temperature. In addition, In addition to this study, it seems necessary to comprehensively consider the relationship between colony photosynthetic ability, metabolite reaction, and rice yield according to climate change.

A programming model for ubiquitous sensor network (USN) applications based on Nano-Qplus is proposed. USN applications mean programs of nodes which are components of sensor network such as sensor, router, sink and actuator. Developers can automatically generate programs of USN applications by setting attributes values of nodes using a script after they model a sensor network. A script for setting attributes values of a node is proposed in this paper. The algorithm of automatic code generation is also described. Developers can easily implement USN applications even if they do not know details of low-level communication, data sharing, and collective operations because the applications are automatically generated from a script. They set only attributes values of nodes using the script. Efforts for USN applications development also are reduced because of automatic code generation. Furthermore, developers can correct errors of applications in the early stage of development through ear]y test based on rapid code generation.

Background: There is a considerable lack of understanding of oral cancer incidence, especially its time trend in Iran. In this study, the authors aimed to analyze time trend of oral cancer incidence with a focus on differences by gender in a period of six years - from 2005 to 2010. Materials and Methods: Both population-based cancer registry and national cancer registry (NCR) data based on pathologic reports from 2005 to 2010 were obtained from the Ministry of Health and Medical Education (MOHME). Population data were also received from Statistical Centre of Iran. Age-standardized incidence rates (ASRs) based on the World Standard Population were then calculated. Finally, Negative Binomial regression was run for time trend analysis. Results: The maximum ASR for males was calculated as 2.5 per 100,000 person-years in 2008 and the minimum was observed as 1.9 per 100,000 person-years in 2005 and 2006. Meanwhile, the maximum ASR for females was estimated as 1.8 per 100,000 person-years in 2009 and the minimum was calculated as 1.6 per 100,000 person-years in 2005 and 2006. Additionally, in females, incidence risk ratio (IRR) did not show a clear decreasing or increasing trend during the six years. Nevertheless, in males an increasing trend was observed. The maximum IRR adjusted for age group and province, for females was reported in 2009 (IRR=1.05 95% CI: 0.90-1.23), and for males was estimated in 2010 (IRR=1/2 95% CI: 1.04 - 1.38). Conclusions: Our findings highlight disparities between oral cancer incidence trends in males and females over the six years from 2005 to 2010.

This paper presents a vowel onset point (VOP) detection method based on the human auditory system. This method maps the "perceptual" frequency scale, i.e. Mel scale onto a linear acoustic frequency, and then establishes a series of Triangular Mel-weighted Filter Bank simulate the function of band pass filtering in human ear. This nonlinear critical-band filter bank helps greatly reduce the data dimensionality, and eliminate the effect of harmonic waves to make the formants more prominent in the nonlinear spaced Mel spectrum. The sum of mel spectrum peaks energy is extracted as feature for each frame, and the instinct at which the energy amplitude starts rising sharply is detected as VOP, by convolving with Gabor window. For the single-word database which contains 12 vowels articulated with different kinds of consonants, the experimental results showed a good average detection rate of 72.73%, higher than other vowel detection methods based on short-time energy and zero-crossing rate.

Objectives: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. Results: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. Conclusions: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

Purpose: The purpose of this study was to investigate the effects of nutrient intake and dietary diversity score (DDS) on osteoporosis after controlling for sex, age, socioeconomic level, drinking, smoking, physical activity, and body mass index (BMI) as mediators using the 2015-2017 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods: This study was focused on the age group of 50s and older by using the 2015-2017 KNHANES data. Subjects diagnosed with osteoporosis were classified as the osteoporosis group, and the other subjects were classified as the normal group. Logistic regression was used to assess the association between nutrient intake and DDS after controlling for mediators. Results: The risk of osteoporosis was 2.38 times lower in the 50-65 age group than in the 75 years and older group. The mediators affecting the incidence of osteoporosis by age group were sex, age, household income level, and education level in the 50-64 age group; sex, education level, drinking, and BMI in the 65-74 age group; and sex, age, current smoking, drinking, BMI, and energy intake in the 75 years and older group. The effect of nutrient intake on osteoporosis, with the exception of vitamin B1, was fully mediated by these mediators. The effect of vitamin B1 was partially mediated by mediators in the age group of 65-74 years, and vitamin B1 was effective for preventing the risk of osteoporosis by 25% when consumed over EAR. The effect of DDS was partially mediated in the age group of 75 years and older, and DDS of 2 or less increased the risk of osteoporosis by 2.59 times. Conclusion: As a result of this study, it is necessary to recommend the balanced intake of various foods including grains, meat·fish·legumes, vegetables, fruits, and dairy products as dietary guidelines for the prevention of osteoporosis and promotion of bone health in the elderly.

This study was carried out to investigate the effects of the seeding dates and growth periods on the growth characteristics, dry matter yield and feed value of corn for silage in paddy field. The experimental design was arranged in a randomized block design with three replications. Treatments consisted of five seeding dates, 1 May (T1), 8 May (T2), 15 May (T3), 22 May (T4) and 29 May (T5). And harvesting time homologized by August 24. Therefore, growing periods were 115 days (T1), 108 days (T2), 101 days (T3), 94 days (T4) and 87 days (T5), respectively. In maturities at harvest time, T1, T2, T3, T4 and T5 were full dent, early dent, late dough, dough and early dough stage, respectively. Plant height and numbers of root system were highest in T5 (p<0.01), but leaf length was higher in T4 than others (p<0.05). Dead leaf, tip filling degree and ear circle were higher in T1 than others (p<0.05, 0.01). Leaf width, ear height, leaf number, ear length, stem diameter, stem hardness and brix were not significantly different among the treatments. Dry matter yield and TDN yield were higher in the order of T1 > T2 > T3 > T4 > T5 (p<0.01). Crude protein, crude ash, NDF, ADF and crude fiber were significantly higher in T4 (p<0.05, 0.01). But crude fat was the highest in T1, T3 was the lowest as compared to other treatments (p<0.01). Total EAA(essential amino acids) were higher in order of T4 > T3 > T1 > T2 > T5, and total NEAA (nonessential amino acids) were higher in order of T1 > T4 > T2 > T3 > T5, and total amino acids were higher in order of T4 > T1 > T3 > T2 > T5. But no significant differences were found among the treatments. TUFA (total unsaturated fatty acid) and TSFA (total saturated fatty acid) were in order of T1 > T2 > T3 > T5 > T4 (p<0.01). Minerals were the highest in T4 (4,721.25 mg/kg), and T2 (2,970.80 mg/kg) was the lowest as compared to other treatments (p<0.05). Based on the above results, seeding dates could be recommended as early May, and harvest times is yellow ripe stage for qualitative and quantitative production of corn for silage in rice paddy field soil.

This study was carried out to investigate the physical characteristics (height, body lenght, chest depth, head type, ear type, body color, eye type and tail type) and genetic diversity using 15 microsatellite DNA markers (PEZ 1, 5, 8, 10, 11, 12, 13, 15, 16, 17, 20, 21, FHC 2010, FHC 2054 and FHC 2079) in 44 random Miryang native dogs(6 months${\sim}$12 years old). The height, body lenght, and chest depth of Miryang native dogs were 43-55 cm(mean 49.5 cm), 45-60 cm(mean 54.3 cm), and 50-64 cm(mean 57.9 cm), respectively. Miryang native dog was medium sized. The head and eye type were reverse-triangle(100%), triangle (90.9%) and newborn moon(9.1%), respectively. Most of body color had white coat color(93.2%), light pink tongue color(100%), light black anal color(90,9%) and pink claw color(100%). The ear type showed erect ear(100%), and half-curled(56.8%), upward(34.1%), curled(9.1%) in tail type, respectively. Number of alleles observed at a single locus ranged from 2 (PEZ 21 and FHC 2010) to 14 (PEZ 13), with average number of alleles per locus of 6.13. The expected heterozygosities of 15 microsatellite loci were estimated based on gene frequencies. The highest expected heterozygosity, 0.863 was estimated in PEZ 13 locus and the lowest, 0.455 in PEZ 21 and FHC 2010 locus. And the mean expected heterozygosity of 15 microsatellite markers was calculated as 0.635. Polymorphic information content (PIC) values were ranged from 0.348 (PEZ 21 and FHC 2010) to 0.837 (PEZ 13), and the mean PIC value was calculated as 0.570. Of the 15 markers, PEZ 10, PEZ 13, PEZ 17 and FHC 2054 loci have relatively high PIC value (> 0.7) in Miryang native dog. In order to determine the efficieney of parentage control, exclusion probabilities (PE) were calculated for each allele. The highest PE 1 and PE 2 in PEZ 13 locus was caculated to 0.548 and 0.710, respectively. And the total exclusion power in PE 1 and PE 2 was calculated to 0.9895 and 0.9996, respectively. These results can give basic information for perservation and research in Miryang native dog, and phylogenetic relationships of the Korean native dog and Asian dog breeds.
