A Feasibility Study of Kinematic Characteristics on the Upper Body According to the Shooting of Elite Disabled Archery Athletes.

The purpose of this study is to compare and analyze the kinematic characteristics of the upper limb segments during the archery shooting of Paralympic Wheelchair Class archers (ARW2-second wheelchair class-paraplegia or comparable disability) and Paralympic Standing Class archers (ARST-standing archery class-loss of 25 points in the upper limbs or lower limbs), where archers are classified according to their disability grade among elite disabled archers. The participants of this study were selected as seven elite athletes with disabilities by the ARW2 ( = 4) and ARST ( = 3). The analysis variables were (1) the time required for each phase, (2) the angle of inclination of the body center, (3) the change of trajectory of body center, and (4) the change of the movement trajectory of the bow center by phase when performing six shots in total.

Comparable Clinical and Radiologic Outcomes Between an Anatomic Tunnel and a Low Tibial Tunnel in Remnant-Preserving Posterior Cruciate Ligament Reconstruction.

Background: There is currently no consensus on the optimal placement of the tibial tunnel for remnant-preserving posterior cruciate ligament (PCL) reconstruction.

Purpose/hypothesis: The purpose of this study was to compare the clinical and radiologic outcomes of remnant-preserving PCL reconstruction using anatomic versus low tibial tunnels. We hypothesized that the outcomes of low tibial tunnel placement would be superior to those of anatomic tibial tunnel placement at the 2-year follow-up after remnant-preserving PCL reconstruction.

In total, 30 patients with subacromial impingement syndrome were recruited and randomly assigned to three groups, the joint mobilization group ( = 10), exercise group ( = 10), and combination group ( = 10).

Effects of Neuromuscular Electrical Stimulation (NMES) Plus Upper Cervical Spine Mobilization on Forward Head Posture and Swallowing Function in Stroke Patients with Dysphagia.

After a stroke, forward head posture occurs, resulting in swallowing dysfunction. Neuromuscular electrical stimulation (NMES) combined with upper cervical spine mobilization has demonstrated enhanced recovery of the swallowing function in stroke patients. This study investigated the therapeutic effects of NMES in conjunction with upper cervical mobilization in stroke patients with dysphagia.

Effects of joint mobilization and stretching on the range of motion for ankle joint and spatiotemporal gait variables in stroke patients.

Background And Purpose: Stroke patients have limited ranges of motion and gait disturbances due to neurological deficits and connective tissue changes. We assessed the effects of joint mobilization and active stretching on ankle joint range of motion and gait in stroke patients.

Methods: In total, 45 stroke patients were evenly divided into three groups: joint mobilization, active stretching, and combination (joint mobilization and active stretching) groups.

Centralized anterior bone plug results in less graft extrusion in patients undergoing medial meniscus allograft transplantation following anterior cruciate ligament reconstruction.

Purpose: This study was performed to analyze the effect of anterior bone plug positioning on clinical and radiological outcomes in patients undergoing medial meniscus allograft transplantation (M-MAT) following anterior cruciate ligament reconstruction (ACLR).

Occurrences of benzalkonium chloride in streams near a pharmaceutical manufacturing complex in Korea and associated ecological risk.

Benzalkonium chloride (BKC) is a commonly used preservative in personal care products and pharmaceutical preparations. However, its ecological risks are not well understood because of lack of monitoring data and ecotoxicological information. In the present study, occurrence of BKC was investigated in the waters near a pharmaceutical manufacturing complex of South Korea and its acute and chronic ecotoxicities were evaluated using Daphnia magna and Japanese medaka (Oryzias latipes).

Position Statement: Exercise Guidelines to Increase Peak Bone Mass in Adolescents.

Background: An increase in bone mineral density during adolescence increases resistance to fractures in older age. The Korean Society for Bone and Mineral Research and the Korean Society of Exercise Physiology developed exercise guidelines to increase the peak bone mass (PBM) in adolescents based on evidence through a systematic review of previous research.

Methods: Articles were selected using the systematic method, and the exercise guidelines were established by selecting key questions (KQs) and defining the effects of exercises based on evidence through a literature review for selecting the final exercise method.

Antidiabetic and Antiobesity Activities of Traditional Kochujang and Doenjang and Their Components.

Chronic effects of bisphenol S and bisphenol SIP on freshwater waterflea and ecological risk assessment.

Bisphenol S (BPS) and 4-hydroxyphenyl 4-isoprooxyphenylsulfone (BPSIP) have been used as substitutes for bisphenol A (BPA) owing to increased regulation of BPA in plastics. In this study, long-term toxicity tests of BPS and BPSIP were performed using Daphnia magna and Moina macrocopa. The predicted no-effect concentration (PNEC) of BPA, BPS, and BPSIP were derived by the assessment factor (AF) method and the species sensitivity distribution (SSD) method.

Exposure to humidifier disinfectants induces developmental effects and disrupts thyroid endocrine systems in zebrafish larvae.

Humidifier disinfectants have been widely used in Korea to prevent the growth of microorganisms in humidifier water. However, their use has been banned since 2011 after epidemiological studies reported humidifier disinfectant induced lung injury. In the present study, the developmental effects of exposure to two humidifier disinfectants (Oxy® and Wiselect) and their main component, polyhexamethylene guanidine (PHMG)-phosphate, were investigated in zebrafish embryos/larvae for seven days.

Co-exposure to ketoconazole alters effects of bisphenol A in Danio rerio and H295R cells.

Chemicals are present in combination in ambient water, however toxicities of their mixtures are not well understood. This study investigated the effects of ketoconazole (KCZ) on the responses induced by bisphenol A (BPA) in zebrafish and in human adrenocarcinoma (H295R) cells. After exposure to BPA alone or mixed with KCZ for 21 d, egg production, relative tissue weights, sex hormone levels, cytochrome P450 (CYP)3a activity, and transcriptions of genes related to CYP metabolism, vitellogenesis, and steroidogenesis were determined in zebrafish.

Consumer exposure and risk assessment to selected chemicals of mold stain remover use in Korea.

Mold stain remover (MSR) is used to clean mold and mildew spots from surfaces and contains a variety of chemical substances. In this study, we estimated the inhalation and dermal exposures associated with the use of trigger spray MSRs, and performed screening-level risk assessments for the use of this type of product in Korea. Inhalation and dermal exposures were estimated using exposure algorithms based on exposure factors obtained from a nationwide survey of 10,000 participants and chemical analyses of the four most popular trigger spray MSRs.
