Purpose: Since coronavirus disease 2019 (COVID-19) spread around the world, non-face-to-face services have emerged as the new normal. The functioning of children with developmental disabilities and cerebral palsy improves when parents, therapists, and institutions cooperate. We aimed to investigate the difficult environment of pediatric physical therapy caused by COVID-19, and grasp parents’ perceptions of home exercise programs. We intend to design home exercise programs for pediatric treatment in the future and create a non-face-to-face pediatric rehabilitation service system based on our findings. Methods: The first survey was conducted on 30 parents who had children with cerebral palsy and developmental disabilities. It was produced after consultation with relevant experts and discussion with the research team, based on a survey conducted in a previous study. The second survey was produced by revising and supplementing the opinions of parents who completed the first survey and consulting experts. Thereafter, an online survey was conducted on 118 parents who had children with cerebral palsy and developmental disabilities. Results: 61.01 % of the parents reported that they were anxious or afraid for their children to be treated for infectious diseases. 83.90 % of the parents reported that the role of parents had increased. 50.00 % of the parents complained of a lack of skill. 85.59 % of the parents reported that they needed a home exercise program provided by the organization. As a non-face-to-face exercise management method, 35.59 % of the parents wanted a real-time video recording electronically mailed to them, and 34.75 % wanted real-time education using video conferencing programs such as zoom. Conclusion: The threat of COVID-19 has further emphasized the importance of social cooperation and management, leading organizations to enter a new era of non-face-to-face rehabilitation services. It is necessary to collect and systematize related studies to reflect more diverse opinions and improve the perceptions of therapists and parents.

In Seoul area, there are so many kennel clubs, veterinary hospital, pet establishment and breeding confers that various problems have occurred. They are crowed pet houses, poor sanitation, stress to puppies, sudden environmental changes to puppies and unvaccination against parvovirus, canine distemper virus, parainfluenza virus, infectious hepatitis caused by Adenovirus type I and Leptospira. Several studies were made to survey the infectious agents involved in acute diarrhea of poppies in Seoul are, such as history taking, physical examination, complete blood count and serum chemistry, histopathological finding, bacterial isolation and identification, and hemagglutination test in feces and hemagglutination inhibition test in serum against parvovirus, respectively. The results obtained are summarized as followed. 1. The percent of PCV (30.5$\pm$5.6) and concentration of Total protein(5.0$\pm$0.8) resulted from statistical analysis are significantly lower than normal values (p<0.05), respectively. In addition, fibrinogen (505$\pm$326) was significantly higher an normal value (p<0.001), Band neutrophil (22.9$\pm$12.7) showed signifiant difference (P<0.01). decreased monocyte (3.2$\pm$2.1) and eosinophil (0.7$\pm$0.8) values appeared statistically significant (p<0.001), lymphocyte (16.7$\pm$9), as well. 2. The concentrations of calcium .(8.0$\pm$2.8), glucose (40.1$\pm$31.4), and albumin (2.0$\pm$0.39) were lower than normal values (p<0.01, p<0.01, p<0.001), respectively. Also Inorganic phosphate (7.1$\pm$2.4), pH (p<7.9f:0.2), and Blood Urea Nitrogen (40.41=37.1) were significantly higher than normal values (p<0.001, p(0.001, p<0.05), respectively. 3. Simple and mixed infections occupied 18% and 82% in the distribution of causes in puppies with acute diarrhea, respectively. 4. As puppies got older, incidence of acute diarrhea caused by Staphylococcus aureus was decreased to 13% and infection of canine distemper virus was increased to 53%, but E coli and canine parvovirus always showed high frequency of outbreak in the body weight ranged from 35g to 7.8Kg. 5. As showed in table 5, infections of E coli and Canine Parvovirus showed high outbreak regardless of the age which is classified into three stages, 35~50 day, 60 day and 75~day to 1 year, canine distemper virus appeared increased, but in case of Staphylococcus aureus, visa versa. 6. In comparison wi methods for the laboratory diagnosis diagnosis parvovirus, Hemagglutination test showed positive reaction in 25% and mean serum antibody titer measured by Hemagglutination inhibition test showed 2779 (n=20). In addition, positive reaction was 90% (18/20). 7. In histopathological studies, enteritic and pneumonic lesions were indicated in 53.7% and 39.5% of samples, respectively. 8. Etiologic diagnosis based on the history taking, clinical signs and histopathological findings in puppies with acute diarrhea and vomiting indicated that 50% of puppies were infected by canine parvovirus and distemper virus. 9. In the parasitological examination made by simple flotation with saturated zinc sulfate tour parasites found were Isospora canis, Toxocara canis, Ancylostoma spp and Toxocara spp. Isospora canis and Toxocara canis were more frequently found among those parasites of diarrhoeic causes in puppies ranged from 35 days to 1 year. Their infestation rates were 15% and 13% respectively.

타이로신은 멜라닌 합성을 조절하는 효소이다. 본 연구에서는 현재까지 미백 효능에 대하여 연구가 진행되지 않은 대나무 중 왕대의 잎 및 대 속 내피 추출물이 유발하는 타이로시나제 활성 및 멜라닌 생성 억제 정도를 조사하였다. 대 잎과 대 속 추출물을 5 mg/ml 농도로 멜라닌 세포에 처리하면 세포의 생존율이 감소하는 것으로 나타났다. 또한 세포독성이 없는 조건의 대 잎과 대 속 추출물을 처리하였을 경우 타이로시나제 활성이 억제되었으며, 멜라닌 생성도 억제되는 것으로 나타났다. 본 연구의 결과를 살펴볼 때 대나무 추출물이 타이로시나제 활성과 발현을 저해함으로써 멜라닌 생성을 억제할 수 있는 후보군으로 가능성이 있는 것으로 생각된다. Tyrosinase is a rate-limiting enzyme that controls the production of melanin. The effect of bamboo (Phyllostachys bambusoides) on tyrosinase activity and melanin synthesis has not been studied. We analyzed the effects of leaf and inner film fractions of bamboo extracts on the inhibition of tyrosinase activity and on melanin production. At a concentration of 5 mg/ml, the extracts of bamboo downregulated the production of melanocytes. In addition, the extracts of bamboo reduced tyrosinase activity and the melanin content in vitro. Our results suggest that bamboo extract may constrain melanin synthesis by inhibition of the activity and expression of tyrosinase.

목적: 대퇴골 전자간 골절후 발생한 내고정의 실패에 대하여 인공 고관절 치환술을 시행하고 수술 시문제점과 결과를 임상적, 방사선학적으로 알아보고자 하였다. 대상 및 방법: 1997년 1월부터 2008년 12월까지 대퇴 전자간 골절로 수술적 치료 후, 내고정 실패를 보여 인공 고관절 치환술을 시행한 29예를 대상으로 실패 원인을 분석하였고, 수술 시 어려운 부분을 알아보고자 하였고, 인공 관절 치환술 후 결과를 임상적 결과(Harris hip score, HHS)와 방사선학적 결과로 평가 하였다. 인공 관절 치환술 후 평균 추시 기간은 34.2개월(12-96개월) 이었다. 결과: 평균 수술 시간은 174분(115-205분), 평균 출혈양은 1,335 ml(750-2,450 ml)였으며 동종 적혈구 농축액이 평균 2.8 unit(0-10 unit) 수혈되어, 내고정물의 제거와 전위된 골절편의 정복에 따른 긴 수술 시간과 많은 출혈양을 보였다. Harris 고관절 점수는 수술전 평균 43에서 85.7점으로 향상되었고, 방사선학적으로 비구컵과 대퇴 주대의 해리를 보이는 경우는 없었고, 탈구와 감염이 각각 1예씩 발생 하였다. 결론: 대퇴골 전자간 골절 후 발생한 내고정의 실패로 인한 인공 고관절 치환술은 비교적 만족할만한 결과를 얻을 수 있었으나 긴 수술시간과 많은 출혈 등의 위험성이 있어, 수술전 술기적 어려움과 대상 환자의 전신상태를 고려하여야 할 것으로 생각된다. Purpose: To analyze the clinical and radiological results of hip arthroplasty following the failed internal fixation of intertrochanteric fractures of the femur. Materials and Methods: We analyzed the reasons for failure in 29 cases of hip arthroplasty from January 1997 through December 2008 in which the hip arthroplasty was necessary due to failed internal fixation of an intertrochanteric fracture of the femur. Furthermore, we tried to find pitfalls encountered when performing the operations. We assessed those patients and drew both clinical (Harris hip score, HHS) and radiological results. The follow-up period was 34.2 months (12-96 months), on average. Results: The average operating time was 174 min.(115-205 min.) and the mean amount of perioperative bleeding was 1,335 ml(759-2,450 ml). The amount of packed RBC transfusion was 2.8 units (0-10units) on average. We could see prolonged operation time and a large amount of blood loss as we performed both the removal of the previously fixed implant and reduction of the displaced bone fragment simultaneously. The mean Harris hip score of the patients was improved from the preoperative score of 43 to the postoperative score of 85.7. No cases showed any radiological signs of loosening of acetabular cups or femoral stems, although an articular dislocation and a postoperative joint infection occurred. Conclusion: Although hip arthroplasties performed because of a failure in internal fixation could provide relatively satisfactory outcomes, as they result in extended surgery time and greater blood loss, a requirement for higher-level surgical skills, and greater consideration required for the systemic conditions of patients before performing surgery.
