An 8-year-old castrated male Korean short hair cat was referred with chronic vomiting, diarrhea, and anorexia. The cat was diagnosed with alimentary lymphoma via fine needle aspiration. Three weeks later, he was presented again with anorexia. Hepatomegaly and hyperechoic change in the liver parenchyma were observed. Computed tomography while awake was performed and revealed hypoattenuation of the hepatic parenchyma. The cat was tentatively diagnosed with feline hepatic lipidosis secondary to alimentary lymphoma. In the feline patient with lymphoma, hepatomegaly is important to differentiate hepatic lipidosis from hepatic infiltration of lymphoma on liver. In the present case, fatty infiltration of the liver was identified via non-invasive, rapid, and convenient computed tomography examination in an awake cat with a lymphoma.

Purpose: The purpose of the study is to examine the factors that influence Korean adolescents' depression and suicidal ideation from individual, social and environmental perspectives by gender. The study used the date of the 2015 Korea Youth Risk Behavior Web-based Survey and the subjects were 68,043 middle and high school students. The levels of depression and suicidal ideation were the dependent variables and the factors influencing the dependent variables included 11 individual factors, 3 social factors and 7 environmental factors. The data were analyzed using odds ratios (OR) from multi-variable logistic regression analysis. As a result, the most significant individual factors that influenced both depression and suicidal ideation were stress and subjective happiness both in boy and girls, the most significant social factor was participation in violence treatment programs, and the most significant environmental factors were economic status, father's educational level, and whether or not they lived with their family. Therefore, programs and policies to improve adolescents' mental health should be developed considering individual, social, and environmental factors.

This study reviewed primary care purchasing issues of the Indonesian single-insurer, BPJS-K, in the context of triangular power relations between the government, the insurer, and the providers, and considered its challenges of purchasing as the national single-insurer. Some literature reviews and interviews with Indonesian stakeholders and residents were used to describe the historical and social contexts of Indonesian healthcare and social health insurance systems especially focusing legal and institutional status of BPJS-K and primary care provision and delivery conditions in remote areas. Though BPJS-K directly belongs to the presidential office of Indonesia, it has limited power in terms of purchasing as a single insurer. Mainly it was due to the lack of primary care resources, Ministry of Health's strong power as the regulator and provider, and BPJS-K's powerlessness against monitoring and quality of care assessment. Ambiguous accountability was another issue among the insurer and the Ministry of Health. This created confusions in primary care provision. It is suggested that each agencies' accountability should be obvious in terms of legal, political, and social contexts.

이 논문은 비콘과 QR코드를 이용해 방문자 식별 및 원격제어를 구현한 스마트 도어락 시스템을 제안한다. 1인가구의 지속적인 증가에 따라 도어락에 원격제어와 보안의 필요성이 부각된다. 기존 논문에서는 동영상 전송방식, 블루투스 통신 방식 등 다양한 기술을 이용하여 구현한 도어락 시스템을 제안한다. 하지만 동영상 전송방식은 센서가 방문자를 오판단하는 경우가 발생하고, IoT기반의 실시간 스트리밍 기술을 이용한 도어락은 해제 후에 사용자가 집의 내부를 모니터링할 수 없다. 이 논문은 비콘과 안드로이드 어플리케이션, 라즈베리파이를 이용한 방문자 식별 및 원격제어를 구현한다. 또한 3D 프린팅을 이용하여 제작한 프로토타입을 보인다.

An 11-year-old, 4.3 kg, mixed breed, intact female dog exhibiting vomiting and a reduced appetite was presented. On physical examination, palpation of the right kidney elicited discomfort. Blood analysis revealed leukocytosis with neutrophilia, and elevation of alkaline phosphatase and blood urea nitrogen. Escherichia coli was detected in urine culture, whereas urine analysis showed absence of glucose. Radiography and ultrasonography suggested that there was gas in the right renal parenchyma, and computed tomography was performed while the dog was awake to investigate the suspected gas in the right kidney. After unilateral ureteronephrectomy, a histological diagnosis of right emphysematous pyelonephritis (EPN) was made. EPN refers to a severe necrotizing infection of the renal parenchyma with gas accumulation in the tissue. It is rare in both human and veterinary medicine, and almost all EPN patients have uncontrolled diabetes mellitus. This case report describes the imaging-based diagnosis of a rare occurrence of unilateral EPN in a non-diabetic dog.

The purpose of the study is to examine the use of medication among adults by comparing the pattern of outpatient prescription drug use with the pattern of long term taking lifestyle drug use. Furthermore, the study investigates factors associated with the use of medication, particularity focusing on socioeconomic factors. Korea Health Panel data of 2008 was used to conduct the study analysis. By performing four different logistic regression models, the study noticed different patterns of the medication use between prescription drugs and lifestyle drugs. More specifically, the study showed that adults with lower education level tend to more frequently receive prescriptions while adults with higher education as well as income level tend to more use lifestyle drugs than their counterparts. Furthermore, other control factors such as age and gender were statistically significant for the use of both prescription and lifestyle drugs in different patterns. The study findings expect that reimbursement structure of drugs may be significantly associated with the different patterns and accordingly the accessability of medicine in particularly vulnerable population. Therefore, these policy factors should be considered in future study to more comprehensively understand about the diverse patterns in the medication use.

The Lactococcus taiwanensis strain K_LL004 was isolated from the gut of a grasshopper (Oxya chinensis sinuosa) collected from local farm in Korea. L. taiwanensis strain K_LL004 is the functional probiotic candidate with an ability to hydrolyse plant polysaccharides. The complete genome of the L. taiwanensis strain K_LL004 contains one circular chromosome (1,995,099 bp) with a guanine + cytosine (GC) content of 38.8%. Moreover, 1,929 Protein-coding sequence, 19 rRNA genes, and 62 tRNA genes were identified based on results of annotation. L. taiwanensis strain K_LL004 has a gene, which encodes hydrolytic enzymes such as beta-glucosidase and beta-xylosidase, that hydrolyzes plant polysaccharides.

Antibiotic resistance (AR) is a complex, multifaceted global health issue that poses a serious threat to livestock, humans, and the surrounding environment. It entails several elements and numerous potential transmission routes and vehicles that contribute to its development and spread, making it a challenging issue to address. AR is regarded as an One Health issue, as it has been found that livestock, human, and environmental components, all three domains are interconnected, opening up channels for transmission of antibiotic resistant bacteria (ARB). AR has turned out to be a critical problem mainly because of the overuse and misuse of antibiotics, with the anticipation of 10 million annual AR-associated deaths by 2050. The fact that infectious diseases induced by ARB are no longer treatable with antibiotics foreshadows an uncertain future in the context of health care. Hence, the One Health approach should be emphasized to reduce the impact of AR on livestock, humans, and the environment, ensuring the longevity of the efficacy of both current and prospective antibiotics.

방향족 친핵성 치환반응을 이용하여 멀티블록형 sulfonated poly(arylene ether sulfone)(SPAES) 공중합체를 합성하였다. 서로 다른 말단(F- 또는 OH-말단)을 가지는 친수성 및 소수성 올리고머를 합성한 후 이를 이용하여 고분자 전해질 막을 합성하였다. 각기 다른 말단이 블록공중합체의 분자량에 미치는 영향을 분석하였고, 서로 다른 친수성구조가 블록고분자의 특성에 어떠한 영향을 미치는지 분석하였다. 합성된 멀티블록고분자는 70%이상의 습도에서 나피온 막과 비슷하거나 우수한 이온전도도를 나타내었고, 특히 SPAES 9의 경우 전습도 영역에서 SPAES 10보다 높은 이온전도도를 보였는데, 이는 친수성 블록내의 술폰산기의 부분 농도가 높아짐에 따라 친수성-소수성 간의 상분리가 발달되어 이온전도도가 향상된 것으로 보인다.
