SAQ training on sprint, change-of-direction speed, and agility in U-20 female football players.

The purpose of the study was to investigate the effects of an 8-week speed, agility, and quickness (SAQ) training on performance changes in linear sprint speed, change-of-direction (COD) speed, and reactive agility of U-20 female football players. Nineteen female football players randomly served as either experimental (n = 9) or control groups (n = 10). The players were tested for physical fitness tests: linear sprint speed including both short and long distances (5- and 10-m sprints without a ball and 20- and 30-m sprints with and without dribbling), COD speed (arrowhead agility test with and without dribbling a ball, Southeast Missouri [SEMO] agility test, and 22-m repeated slalom dribbling test), and reactive agility.

A survey of the impact of COVID-19 on the management of animal experiments and laboratory animal facilities in Korea.

The pandemic has affected the lives of people all over the world. The effects of the pandemic on laboratory animal facilities and their operations through this unusual global event are poorly understood. Here, we have applied a methodological framework of qualitative approach including semi-structured interviews to investigate laboratory animal operations in Korea and how it has shaped the on-going management and laboratory operations of such facilities.

Use of laboratory animals and issues regarding the procurement of animals for research in Korea.

Background: Laboratory animals remain critical to biomedical research, despite the increasing availability of alternative approaches. Indeed, scientists strive to reduce and refine and replace the use of laboratory animals, even in the face of public calls for ever-more stringent regulation for the protection and care of animals in research. This report outlines the current status and legal regulatory issues with regard to the procurement and use of animals for research in Korea.

Defectronics based photoelectrochemical properties of Cu ion doped hematite thin film.

The concentration of guest elements (dopants) into host materials play an important role in changing their intrinsic electrical and optical properties. The existence of hetero-element induce defect in crystal structure, affecting conductivity. In the current work, we report Cu ion into hematite in the defectronics point of view and their photoelectrochemical properties.

Improvement plans on the operation of the Institutional Animal Care and Use Committee: focusing on the case of Seoul National University.

Background: The Institutional Animal Care and Use Committee (IACUC) became compulsory in 2008 by the Animal Protection Act in Korea. Seoul National University (SNU), which conducts 5% of Korea's total animal protocol reviews and uses 10% of national laboratory animal usage, has been influential in the review of animal protocols and management of animal facilities. This study was undertaken to suggest the operational improvement of the IACUC.

Operational issues of the Institutional Animal Care and Use Committee in Korea.

Korean Institutional Animal Care and Use Committee (IACUC) is currently facing some operational pressing issues. 1) Review of the animal protocol containing controversial technology. 2) Review of the multi-institution animal protocol.

The status and issues of the Institutional Animal Care and Use Committee of Seoul National University: from its establishment to the present day.

The Institutional Animal Care and Use Committee (IACUC) of Seoul National University (SNU) plays a key role in monitoring and managing the humane use of animals in scientific research. Here, as one of the pioneers of the IACUC in Korea, we reported SNU-IACUC operations and activities including committee establishment and legal formulation, protocol review, and post-approval monitoring of protocols, which the IACUC has undertaken in the last decade. In addition, legal regulations and improvements were also discussed, and encompassed the limited number of committee members and the single IACUC policy in Korea.

Health Surveillance of Penguins in the Barton Peninsula on King George Island, Antarctica.

Samples from 29 adult Gentoo (Pygoscelis papua), Chinstrap (Pygoscelis antarcticus), and Adélie Penguins (Pygoscelis adeliae) at the King Sejong Station on Nar̢ ebski Point, King George Island, Antarctica, were investigated to detect antibodies to avian influenza, Newcastle disease virus, infectious bursal disease virus, infectious bronchitis virus, Mycoplasma, and Salmonella. Antibodies were identified from one Gentoo Penguin and one Chinstrap Penguin against infectious bronchitis virus; from one Gentoo Penguin against Newcastle disease virus; from one Gentoo Penguin against Mycoplasma synoviae; and from two Chinstrap Penguins against Salmonella pullorum. Thirty-three dead penguin chicks were collected from the breeding colony for necropsy, histopathological examination, and polymerase chain reaction.

Balancing Personal Privacy and Public Safety During COVID-19: The Case of South Korea.

There has been vigorous debate on how different countries responded to the COVID-19 pandemic. To secure public safety, South Korea actively used personal information at the risk of personal privacy whereas France encouraged voluntary cooperation at the risk of public safety. In this article, after a brief comparison of contextual differences with France, we focus on South Korea's approaches to epidemiological investigations.

Loss of glutathione peroxidase 3 induces ROS and contributes to prostatic hyperplasia in Nkx3.1 knockout mice.

Background: Glutathione peroxidase 3 (Gpx3) protects cells from oxidative stress, and its reduced expression in human prostate cancer has been reported.

Objectives: We hypothesized that Gpx3 might play an important role in the development of prostatic intraepithelial neoplasia (PIN), a pre-cancerous state of the prostate, and aimed to highlight the underlying molecular mechanism.

Materials And Methods: The following double-knockout mice Nkx3.

Effects of Korean hand acupressure on opioid-related nausea and vomiting, and pain after caesarean delivery using spinal anaesthesia.

Objective: This study examined the effects of Korean hand acupressure on opioid-related nausea and vomiting, and pain after caesarean delivery.

Methods: Fifty participants were randomly assigned to an acupressure group or a control group. Korean hand acupressure discs were applied for 24 h onto 12 acupressure points (K-9, F-4 for nausea and vomiting; M-3, M-4, L-4, H-2, H-3, H-7 for abdominal pain; and I-38, J-2 for back pain).

Changes of bone metabolism based on the different interventions with exercise type or additional intake material in ovariectomized rats.

Purpose: This study is aimed at providing clear guidance on treatment and prevention of osteoporosis by comparing and analyzing some well-known methods out of drug and exercise therapies.

Methods: For this purpose, eight-week experiments (drug therapy and exercise therapy) were carried out by using rats whose menopause was induced by the removal of an ovary. In the treatment of the drug therapy, the effects of soy protein, one of the well-known alendronate and estrogen replacement therapy, were compared and analyzed.

Plantar Pressure Distribution During Robotic-Assisted Gait in Post-stroke Hemiplegic Patients.

Objective: To assess the plantar pressure distribution during the robotic-assisted walking, guided through normal symmetrical hip and knee physiological kinematic trajectories, with unassisted walking in post-stroke hemiplegic patients.

Methods: Fifteen hemiplegic stroke patients, who were able to walk a minimum of ten meters independently but with asymmetric gait patterns, were enrolled in this study. All the patients performed both the robotic-assisted walking (Lokomat) and the unassisted walking on the treadmill with the same body support in random order.

Scoring of prognostic factors that influence long-term survival in patients with hepatic metastasis of colorectal cancer.

Backgrounds/aims: To find independent predictors that affect the survival in patients with hepatic metastasis of colorectal cancer after surgery and to devise a risk scoring system.

Methods: Among 150 patients who underwent hepatic resection after diagnosis of colorectal cancer with hepatic metastasis between March 1994 and February 2009, we analyzed clinical, pathologic and outcome data retrospectively.

Results: The 1-year survival rate was 83%, and the 5-year survival rate was 35%.
