An act of children's welfare was made in 1961 for the first time in Korea but it had been nothing but the name in view of practical impact to prevention of child abuse. Real undertakings of Child Abuse Prevention were commenced overtly since 2000 in Korea, when the law for children's welfare was revised to put protective settings for the victims and to establish criterion for children's safety. The history of Child Abuse Prevention is very short in Korea but the reporting cases increased very fast from 4,133 cases in 2001 up to 9,570 cases in 2008 with the enthusiastic activities from people of the associated organizations along with the national supports. But the portion reported by the mandated reporters such as teachers or doctors is still low compared to those of the developed countries. The National Child Protection Agency (NCPA) was founded in 2001 by the Ministry of Health and Welfare to prevent child abuse and to aid recovery of abused and neglected children including their families, through the cooperation of related organizations. NCPA refers reported cases of child abuse to appropriate local centers, operates a computer database system for case management, publicizes national reports of child abuse on a yearly basis and technically supports the Local Child Protection Agency (LCPA) by developing scales for assessment of child abuse and neglect and distributing programs for the education of mandatory reporters. LCPAs operate 24-hour telephone hotline, investigate and visit homes and provide in home services networking with local resources, and operate multidisciplinary teams for screening child abuse victims and supervising case management through multimodal systems. We summarized the present state of child abuse in Korea and reviewed the operating systems for child protection in this country. Through this article, we hope that medical peoples are to be informed on the seriousness of child abuse and to be able to devote themselves for the prevention of child abuse.

This paper discusses the implications of the birth notification system and the Protected Birth Act in Korea. Aiming to prevent infanticide and abandonment of infants, the law will enter into force on July 19, 2024 in South Korea. The birth notification system mandates that both parents and the head of the medical institution where the birth occurred must report the event. In parallel, the Protected Birth Act will be implemented, allowing pregnant women in crisis who wish to remain anonymous, the option to give birth outside of a hospital setting in a way that safeguards the life and health of the child. However, many issues are being raised in Korean society in advance of the implementation of the Protected Birth Act. There is widespread concern that the Protected Birth Act fails to protect either women or children, especially as it raises issues regarding the need for legislation to protect children with disabilities and to address gaps for migrant women and children. This paper examines the gender and healthcare issues relating to the Protected Birth Act, focusing on women's health and human rights. The Act continues to perpetuate discrimination against out-of-wedlock pregnancies and upholds the ideology of the traditional family model. Furthermore, the legislative process did not address protective measures for the various reasons behind child abandonment. Critical issues such as women's autonomy, safe pregnancy termination, and paternal responsibility in childbirth are also notably absent. However, with the Act set to take effect soon, it is crucial for healthcare providers to comprehend the rationale and procedures associated with birth notification and the Protected Birth Act, and to prepare for its nationwide implementation. The law defines the socially vulnerable as its main beneficiaries, and it is necessary to strengthen social safety nets to improve their access to healthcare, eliminate prejudice and discrimination against out-of-wedlock pregnancies, and embrace the diversity of our society. We eagerly anticipate future discussions on gender and healthcare issues, as well as amendments to the law that reflect real-world circumstances to provide genuine protection for pregnant women in crisis and their infants.

Purpose : To analyze the eyeglasses supply system for ametropic soldiers in ROK military. Methods : We investigated and analyzed the supply system of eyeglasses for the ametropic soldiers provided by the Korean military. The refractive powers and corrected visual acuity were measured for 37 ametropic soldiers who wear insert glasses for ballistic protective and gas-masks supplied by the military based on their habitual prescriptions. Full correction of refractive error was prescribed for subjects having less than 1.0 of distance visual acuity, and comparison was held for inspecting the changes in corrected visual acuity. Suggestions were provided for solving the issues regarding current supplying system, and this study investigated the applicabilities for utilizing professional optometric manpower. Results : The new glasses supplied by army for ametropic soldiers were duplicated from the glasses they worn when entering the army. The spherical equivalent refractive powers of the conventional, ballistic protective and gas-mask insert glasses supplied for 37 ametropic soldiers were $-3.47{\pm}1.69D$, $-3.52{\pm}1.66D$ and $-3.55{\pm}1.63D$, respectively, and the spherical equivalent refractive power of full corrected glasses was $-3.79{\pm}1.66D$, which showed a significant difference(p<0.05). The distant corrected visual acuity measured at high and low contrast(logMAR) of conventional, ballistic protective and gas-mask insert glasses were $0.06{\pm}0.80$, $0.21{\pm}0.82$, $0.15{\pm}0.74$, $0.34{\pm}0.89$, $0.10{\pm}0.70$ and $0.22{\pm}0.27$, respectively, while the corrected visual acuity by full corrected glasses were increased to $0.02{\pm}1.05$, $0.10{\pm}0.07$, $0.09{\pm}0.92$, $0.26{\pm}0.10$, $0.04{\pm}1.00$ and $0.19{\pm}1.00$, respectively. There was a significant difference(p<0.05) except for the case of the low contrast corrected visual acuity of the conventional and gas-mask insert glasses. The procedure for ordering, dispensing, and supplying military glasses consists of 5 steps, and it was found that approximately two weeks or more are required to supply from the initial examination. Conclusion : The procedure of supplying the military glasses showed three issues: 1) a lack of refraction for prescription system, 2) relatively long length of time required for supplying the glasses, 3) an inaccurate power of supplied glasses. In order to solve those issues, in the short term, education is necessarily required for soldiers on the measurement of the refractive powers, and in the near future, further standard procedures for prescription of glasses as well as the securement of optometric manpower are expected.

Objective: This study was a preliminary study for the prevention programs for farmers' occupational diseases. It selected the priorities recognized by farmers, such as occupational diseases, and also identifies the effectiveness and feasibility of prevention programs among diseases recognized by farmers. Therefore, we plan to use it as basis data for future farmer safety and health programs. Method: The subjects of the study were farmers living in the region, selected through a snowball recruitment method, and a total of 671 people were targeted. The priority selection method was the Basic Priority Rating System (BPRS) method, and among the occupational diseases, programs to prevent musculoskeletal diseases, cardiovascular and respiratory diseases, and pesticide poisoning were surveyed on the effectiveness and feasibility of farmers. Results: Among occupational diseases, the highest priority was musculo-skeletal disease, followed by respiratory disease and pesticide poisoning. Among the programs for musculoskeletal disease, 'use of agricultural work convenience equipment and auxiliary tools' had the highest perceived effectiveness and feasibility. Among the five programs for pesticide poisoning, 'equipment of protective equipment such as pesticide protective clothing/glove' had the highest effectiveness at 67.4%, and 'compliance with pesticide use instructions' had the highest level of feasibility at 64.3%. Among the four programs to prevent respiratory diseases, 'wearing a dust mask or gas mask' was the highest at 65.5% in terms of both effectiveness and feasibility. Conclusion: When carrying out safety and health programs for farmers, the priorities recognized by farmers should be taken into consideration, and the program contents should also be developed taking into account the size of effect and feasibility recognized by farmers.

Skin damage is mainly caused by environmental factors such as ultraviolet light, heat, and smoking. It is known that reactive oxygen species production is commonly involved in the pathogenesis of skin damage induced by these factors, causing skin aging. Pyrus pyrifolia Nakai continues to be a popular and highly consumed fruit in many countries with known beneficial effects including antitumor, antioxidative, and anti-inflammatory effects. However, there is no evidence of a therapeutic effect of Pyrus pyrifolia extract (PPE) against skin aging via inhibition of mitochondria-mediated apoptosis. In this study, we investigated PPE protective effect against photoaging induced by UVB ($50mJ/cm^2$) in HS68 human dermal fibroblasts. Lactate dehydrogenase assay showed that PPE significantly protected HS68 cells against UVB-induced damage in a dose-dependent manner. Other assays using DCF-DA demonstrated that PPE protected HS68 cells by regulating reactive oxygen species production. PPE also regulated mitochondrial dysfunction and mitochondrial membrane potential induced by UVB, and inhibited UVB-induced caspase-3 activity. These results indicate that PPE protects human dermal fibroblasts from UVB-induced damage by regulating the oxidative defense system.

Objective : Myeongganbo (MGB) composited with Hovenia Semen, Puerariae Radix and Dioscoreae Rhizoma is the prescription for protection of liver function. The purpose of this study was to investigate the effects of MGB extract against acetaminophen (APAP)-induced liver injury in mice. Methods : MGB extract was prepared by extracting with hot distilled water. The extract was freeze-dried following filtration through vacuum distillation system. Mice fasted for overnight were orally administrated with or without MGB extract of different doses (25-200 mg/kg/day). After 30 min, APAP was orally applied with a single dose (400 mg/kg). The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured in plasmas of mice. Glutathione (GSH), glutathione peroxidase GSH-px), cyclooxygenase-2 (COX-2) activity and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level were investigated in liver homogenates. Liver sections were stained with haematoxylin & eosin, anti-TNF-${\alpha}$ and anti-mouse COX-2 antibodies. Results : APAP treatment remarkably increased AST and ALT activities in plasma but inhibited GSH and GSH-px levels in liver homogenates. Also, liver injury was significantly accelerated by APAP treatment. Furthermore, APAP remarkably elevated COX-2 activity and TNF-${\alpha}$ levels in liver homogenates. However, administration of MGB extract was able to counteract these effects. Histological studies provided supportive evidence for biochemical and molecular analysis Conclusions : These results suggest that MGB extract has potent hepatoprotective effect against APAP-induced liver injury, these properties may contribute to liver disease care.

The present study was designed to investigate the cardioprotective effects of Korean Red Ginseng extract (KRG) on isoproterenol (ISO)-induced cardiac injury in rats, particularly in regards to electrocardiographic changes, hemodynamics, cardiac function, serum cardiac enzymes, components of the myocardial antioxidant defense system, as well as inflammatory markers and histopathological changes in heart tissue. ISO (150 mg/kg, subcutaneous, two doses administered at 24-hour intervals) treatment induced significant decreases in P waves and QRS complexes (p<0.01), as well as a significant increase in ST segments. Moreover, ISO-treated rats exhibited decreases in left-ventricular systolic pressure, maximal rate of developed left ventricular pressure ($+dP/dt_{max}$) and minimal rate of developed left ventricular pressure ($-dP/dt_{max}$), in addition to significant increases in lactate dehydrogenase, aspartate transaminase, alanine transaminase and creatine kinase activity. Heart rate, however, was not significantly altered. And the activities of superoxide dismutase, catalase and glutathione peroxidase were decreased, whereas the activity of malondialdehyde was increased in the ISO-treated group. ISO-treated group also showed increased caspase-3 level, release of inflammatory markers and neutrophil infiltration in heart tissue. KRG pretreatment (250 and 500 mg/kg, respectively) significantly ameliorated almost all of the parameters of heart failure and myocardial injury induced by ISO. The protective effect of KRG on ISO-induced cardiac injury was further confirmed by histopathological study. In this regard, ISO treatment induced fewer morphological changes in rats pretreated with 250 or 500 mg/kg of KRG. Compared with the control group, all indexes in rats administered KRG (500 mg/kg) alone were unaltered (p>0.05). Our results suggest that KRG significantly protects against cardiac injury and ISO-induced cardiac infarction by bolstering antioxidant action in myocardial tissue.

Background: The intrathecal (IT) $GABA_A$ receptor antagonist, bicuculline (BIC), results in tactile allodynia (TA) through disinhibition in the spinal cord. Such disinhibition is considered to be an important mechanism for neuropathic pain. Agmatine, an endogenous polyamine, has a neuro-protective effect in the central nervous system. We investigated the analgesic effects and mechanisms of agmatine action on BIC-induced TA. Methods: Male Sprague-Dawley rats, weighting 250-300 g, were subjected to implantations of PE-10 into the lumbar subarachnoid space for IT drug injection. Five days after surgery, either $10{\mu}l$ of normal saline (NS) or agmatine ($30{\mu}g$ or $10{\mu}g$) in $10{\mu}l$ NS were injected 10 min prior to BIC ($10{\mu}g$) or NMDA ($5{\mu}g$). We assessed the degree of TA (graded 0: no response, 1: mild response, 2: moderate response, 3: strong response) every 5 min for 30 min. Areas under curves and degree of TA were expressed as mean ${\pm}$ SEM. Results were analyzed using one-way ANOVA followed by a Tukey test for multiple comparisons. P < 0.05 was considered significant. Results: IT BIC-induced strong TA reached its peak and plateaued between 10 to 15 min. IT NS-NMDA induced mild transient TA for up to 15 min. Preemptive IT AG attenuated IT BIC-induced TA dose dependently and preemptive IT AG10 completely abolished the IT NMDA-induced TA. Conclusions: Preemptive IT AG attenuated the IT BIC-induced TA through inhibitory actions on postsynaptic NMDA receptor activation. AG might be a viable therapeutic option in the treatment of neuropathic pain.

Lin28a has diverse functions including regulation of cancer, reprogramming and regeneration, but whether it promotes injury or is a protective reaction to renal injury is unknown. We studied how Lin28a acts in unilateral ureteral obstruction (UUO)-induced renal fibrosis following unilateral ureteral obstruction, in a mouse model. We further defined the role of Lin28a in transforming growth factor (TGF)-signaling pathways in renal fibrosis through in vitro study using human tubular epithelium-like HK-2 cells. In the mouse unilateral ureteral obstruction model, obstruction markedly decreased the expression of Lin28a, increased the expression of renal fibrotic markers such as type I collagen, α-SMA, vimentin and fibronectin. In TGF-β-stimulated HK-2 cells, the expression of Lin28a was reduced and the expression of renal fibrotic markers such as type I collagen, α-SMA, vimentin and fibronectin was increased. Adenovirus-mediated overexpression of Lin28a inhibited the expression of TGF-β-stimulated type I collagen, α-SMA, vimentin and fibronectin. Lin28a inhibited TGF-β-stimulated SMAD3 activity, via inhibition of SMAD3 phosphorylation, but not the MAPK pathway ERK, JNK or p38. Lin28a attenuates renal fibrosis in obstructive nephropathy, making its mechanism a possible therapeutic target for chronic kidney disease.

A huge number of chemicals are produced and used in the world, and some of them can have negative effects on the reproductive health of workers. To date, most chemicals and work environments have not been studied for their potential to have damaging effects on the workers' reproductive system. Because of the lack of information, many workers may not be aware that such problems can be related to occupational exposures. Newly industrialized countries such as Republic of Korea have rapidly amassed chemicals and other toxicants that pose health hazards, especially to the reproductive systems of workers. This literature review provides an overview of peer-reviewed literature regarding the teratogenic impact and need for safe handling of chemicals. Literature searches were performed using PubMed, Google Scholar, and ScienceDirect. Search strategies were narrowed based on author expertise and 100 articles were chosen for detailed analysis. A total of 47 articles met prespecified inclusion criteria. The majority of papers contained studies that were descriptive in nature with respect to the Medical Subject Headings (MeSH) terms and keywords: "reproductive and heath or hazard and/or workplace or workers or occupations." In the absence of complete information about the safe occupational handling of chemicals in Republic of Korea (other than a material safety data sheet), this review serves as a valuable reference for identifying and remedying potential gaps in relevant regulations. The review also proposes other public health actions including hazard surveillance and primary prevention activities such as reduction, substitution, ventilation, as well as protective equipment.
