The negative impacts of roads on wildlife mortality have been well documented, and one of the most significant impact is wildlife-vehicle collisions (WVCs) in most countries throughout the world. While road impacts on wildlife are a truly global concern with a large socio-economic cost, few researches in Korea have been quantified road-kill occurrence on highways or identified extensively seasonal and geographic patterns of this phenomenon. Therefore, we analyzed highway mortality of wild mammals in Korea using database from five years of nation-wide data on WVCs, and estimated road-kill density by standardizing on per km and per $10^3$ vehicle basis. During 2008 through 2012, a total of 10,940 wildlifes were reported killed on highways, with an average of 2,188 cases per year. There were 2,376 road-kills in 2012, and this equates to 0.01 road-kills per km per week or one road-kill every 88.5 km per week. For time of day, road-kills occurred more frequently in the early morning (05:00-08:00, 38.3%), and day of week did not have a significant influence in any individual year. The road-kill was highest in the spring (March- May, 33.0%) and least in the winter (December-February, 16.1%), and the most frequently killed native species were of Korean water deer (79.7%), raccoon dog (12.7%), Korean hare (3.1%), and leopard cat (1.2%). The overall standardized kill-rate (number/10 km/1,000 vehicles/month) in 2012 was 0.057 with highest on Dangjinyeongdeok highway (0.476), followed by Yeongdong (0.274), Sooncheonwanju (0.233), Iksanpohang (0.187), and Joongang (0.150). This study highlights that the frequency of WVCs are prevalent throughout the highways in Korea. Further work is needed to determine whether such a level of mortality is sustainable from an ecological point of view.

It is thought as more important for us to understand foreign countrie's culture in the modern society. because the world is becoming closer day by day thiough the develepment of communication and mass-media. Cross-cultural study could play a role to give an opportunity for people to understand foreign countrie’s culture easily.In this respect, this study was planned to find out similarity and difference between Danish and Korean folk tables made and used before the 20th century during the 18th-l9th century as a part of the comparative study of folk furniture between the two countries. It would be very interesting if we could find something valuable between Danish and Korean folk furniture. because they are located very far away each other geographically with less cultural communication before.There were more differences than similarity between the folk tables of the two countries and major findings were as followings : Firstly, there were many kinds of space-saving tables in Denmark. whereas only a few kinds of tables which could be removed easily after their usage were found in KoreaSecondly, Banish folk tables were more emphasized on the function rather than decoration. Whereas Korean folk tables were smaller lower and more decorative than Danish ones to fit their life-style of sitting on the floor.Thirdly, many Danish folk tables were made of bare wood. while Korean ones were finished by transparent lacquer or vegetable oil. Stone tops if tables were rare in both countries. Lastly. there were common factors in the design of legs of folk tables in both countries. It was interesting that animal legs such as deg tiger cat. lion, and eagle were used for design motif of the table legs. But trestle leg, cross leg and gate leg were not found in Korean folk tables. As a conclusion, throughout this study, it became obvious that life-style was one of the most important factor influencing on the design of furniture.

Diabetes mellitus is a chronic disorder which affects millions of population worldwide. Global estimates published in 2010 reported the world diabetic prevalence as 6.4%, affecting 285 million adults. Foot ulceration and wound infection are major forms of disabilities arising from diabetic diseases. This study was aimed to develop a natural antimicrobial finishing on medical grade textile that meets American Association of Textiles Chemists and Colorists (AATCC) standard. The textile samples were finished with the ethanolic extract of Penicillium amestolkiae elv609, an endophytic fungus isolated from Orthosiphon stamineus Benth (common name: cat's whiskers). Endophyte is defined as microorganism that reside in the living plant tissue, without causing apparent disease symptom to the host. The antimicrobial efficacy of the ethanolic extract of P. minioluteum was tested on clinical pathogens isolated from diabetic wound. The extract exhibited significant inhibitory activity against 4 bacteria and 1 yeast with the minimal inhibitory concentration ranged from 6.25 to 12.5 mg/mL. The results indicate different susceptibility levels of the test microorganism to the ethanolic extract. However, the killing activity of the extract was concentration-dependent. The finished medical textile showed excellent antimicrobial efficacy on AATCC test assays. All the microbial cultures treated with the textile sample displayed a growth reduction of 99.9% on Hoheinstein Challenge Test. The wash durability of the finished textile was found good even after 50 washes with commercial detergent. Besides, the gas chromatography mass spectrometry analysis showed that 6-octadecenoic acid and diethyl phthalate were the main bioactive constituents of the extract. In conclusion, the developed medical textile showed good antimicrobial efficacy on laboratory tests. This work can be extended to in vivo trials for developing healthcare textile products for antimicrobial applications.

Some promoters were isolated and characterized from the genome of Leuconostoc mesenteroides SY2, an isolate from kimchi, a Korean traditional fermented vegetable. Chromosomal DNA of L. mesenteroides SY2 was digested with Sau3AI and ligated with BamHI-cut pBV5030, a promoter screening vector containing a promoterless cat-86. Among E. coli transformants (TFs) resistant against Cm (chloramphenicol), 17 were able to grow in the presence of $1,000{\mu}g/ml$ Cm and their inserts were sequenced. Transcription start sites were examined for three putative promoters (P04C, P25C, and P33C) by primer extension. Four putative promoters were inserted upstream of a promoterless ${\alpha}$-amylase reporter gene in $pJY15{\alpha}$. ${\alpha}$-Amylase activities of E. coli TFs containing $pJY15{\alpha}$ (control, no promoter), $pJY03{\alpha}$ ($pJY15{\alpha}$ with P03C), $pJY04{\alpha}$ (with P04C), $pJY25{\alpha}$ (with P25C), and $pJY33{\alpha}$ (with P33C) were 66.9, 78.7, 122.1, 70.8, and 99.3 U, respectively. Cells harboring $pJY04{\alpha}$ showed 1.8 times higher activity than the control. Some promoters characterized in this study might be useful for construction of food-grade expression vectors for Leuconostoc sp. and related lactic acid bacteria.

The population of pet cats has increased significantly, from 0.3% in 2002 to 5.6% in 2017. Large-scale feline demographic and disease data from Korea are lacking. The aim of this study was to investigate the demographic data (breed, sex, and age) and disease distribution of cats who visited private veterinary practices in Korea. Data including breed, sex, age, and disease, were compiled from 32,728 electronic medical records from 30 selected private veterinary practices, between January 1, 2016, and December 31, 2017. Diseases were classified based on the International Classification of Diseases 11 by the World Health Organization, and then compared and cross-analyzed according to breed, sex, and age. Korean shorthair was the most common breed. There was a high distribution of young cats, with 77.6% of the cats under 4 years of age, and an average age of 2.5 years. Diagnoses related to preventative medicine were the most frequent and diagnoses common to young cats had higher incidence. This demographic data and information about disease distribution can be used as a basis for future research and may be helpful for determining priorities in the diagnosis of diseases and establishing strategies for health management in cats.

Giardiasis is widespread all over the world, and it is a disease that causes both acute and chronic digestive symptoms. It is zoonotic disease that affects animals and humans. There are few studies on giardiasis in stray cats due to difficulties in catching and sampling. Therefore, this study evaluated the prevalence of giardiasis in stray cats in the Daejeon city because of increasing interest as zoonotic disease. The specimens were the feces of stray cats captured for the neutering project (TNR) in Daejeon; 30 fecal samples were collected from 2021 to 2022 in each of 5 districts in Daejeon. A total of 150 samples were collected. All samples were tested for giardiasis using the Giardia SNAP kit (SNAP^Ⓡ test, IDEXX Laboratories. Inc., Westbrook, ME). The overall prevalence rate was 46 out of 150 cats (30.7%). By age, 25 out of 71 juvenile cats (35.2%) were positive, and 21 out of 79 adult cats (26.6%) were positive. A total of 19 out of 69 cats (27.5%) with diarrhea were positive, and 27 out of 81 asymptomatic cats (33.3%) were positive. For gender, 38 out of 99 females (38.4%) were positive, and 8 out of 51 males (15.7%) were positive. The positive rate of giardiasis in stray cats was over 30%, which is high compared to other research results. It is necessary to increase the public's awareness of the value of deworming stray cats and the sanitation of people who have come into contact with them.

외로움은 사회적 연결 욕구가 충족되지 못할 때 갖게 되는 고통스러운 경험이다. 의인화는 동물이나 무생물(예: 컴퓨터)에게 인간의 속성을 부여하는 것인데 비해, 비인간화(dehumanization)는 의인화와 반대되는 과정으로서, 인간을 동물이나 무생물로 인식하는 것이다. 본 연구의 목적은 외로움, 사회적 연결욕구 및 의인화의 관계를 분석하고, 외로움이 의인화, 외집단의 비인간화에 끼치는 영향을 검증하는데 있다. 연구 1에서는 외로움, 사회적 연결욕구 및 의인화의 관계를 분석하고자 외로움 질문지와 의인화과제를 실시하였다. 그 결과 참가자가 외로움을 강하게 느낄수록 컴퓨터와 동물에 대한 의인화의 경향이 더 뚜렷하게 나타났다. 연구 2에서는 실험상황에서 작문과제를 통해 연구참가자들에게 외로움의 정서를 유도한 후, 통제조건에 비해 의인화, 비인간화의 경향 및 이웃에 대한 신뢰감에서 차이가 나타나는지를 비교하였다. 그 결과, 외로움의 조건에서 통제조건보다 의인화, 비인간화 및 이웃에 대한 부정적 정서가 유의하게 더 높게 나타났다. 이 결과는 동물과 무생물에 대한 의인화는 외로움을 해결하기 위한 사회적 연결욕구와 관계가 있으며, 외로움은 다른 인간에 대한 비인간화 및 이웃에 대한 비호감에 영향을 끼칠 가능성을 시사한다.

Helicobacter pylori as the second most common cause of gastric cancer in the world infects approximately half of the developed countries population and 80% of the population living in developing countries. Integrons as genetic reservoirs play major roles in dissemination of antimicrobial resistance genes. To the best of our knowledge, this is the first study to report carriage of class 1 and 2 integrons and associated gene cassettes in H. pylori isolates from Iran. This cross-sectional study was conducted in Tehran among 110 patients with H. pylori infection. Antimicrobial susceptibility testing (AST) for H. pylori strains were assessed by the micro broth dilution method. Class 1 and 2 integrons were detected using PCR. In order to determine gene cassettes, amplified fragments were subjected to DNA sequencing of both amplicon strands. The prevalence of resistance to clarithromycin, metronidazole, clarithromycin, tetracycline, amoxicillin, rifampin, and levofloxacin were 68.2% (n=75), 25.5% (n=28), 24.5% (n=27), 19.1% (n=21), 18.2% (n=20) and 16.4% (n=18), respectively. Frequency of multidrug resistance among H. pylori isolates was 12.7%. Class 2 integron was detected in 50 (45.5%) and class 1 integron in 10 (9.1%) H. pylori isolates. The most predominant gene cassette arrays in class 2 integron-bearing H. pylori were included sat-era-aadA1, dfrA1-sat2-aadA1, blaoxa2 and, aadB whereas common gene cassette arrays in class 1 integron were aadB-aadA1-cmlA6, aacA4, blaoxa2, and catB3. The high frequency of class 2 integron and multidrug resistance in the present study should be considered as a warning for clinicians that continuous surveillance is necessary to prevent the further spread of resistant isolates.

살리실산은 식물의 생장 및 발달, 항산화 방어기작, 광합성 작용 그리고 생물적 및 비생물적 스트레스 조건에서 다양한 생리적 기능을 조절하는 물질로 알려져 있다. 본 연구에서는 고온·건조 스트레스 조건에서 살리실산 경엽처리가 고추의 생육, 광합성 특성 및 항산화효소 활성에 미치는 영향을 구명하고자 하였다. 광합성 특성 측정결과 광합성 속도, 기공전도도 및 증산 속도가 증가하였고, 3회차 처리에서 가장 높았다. 세포내 MDA와 H₂O₂ 함량은 살리실산 3회차 처리에서 현저하게 감소하는 경향을 보였다. APX, CAT, POD 및 SOD 활성이 현저하게 증가하였으며, 무처리 대비 최대 247, 318, 55 및 54% 증가하였다. 고추의 생육 특성은 무처리구와 유의한 차이를 보이지 않았으나, 상품 수량은 15% 정도 증가하였다. 이러한 결과들을 종합해 볼 때, 살리실산의 경엽처리는 고추의 광합성 특성과 항산화효소 활성을 증진시켜 고온·건조 스트레스에 의한 피해 경감에 긍정적 효과를 유발함을 확인하였다.
