PURPOSE: Glass particle contamination of the contents of single-dose glass ampules can occur upon opening. Different aspiration techniques, different sizes of needles, different sizes of ampules, and different cutting methods were studied to determine if they had any effect on glass particle contamination. METHOD: Different aspiration techniques(with filter, without filter), different sizes of needles(18G, 25G), different sizes of ampules(2ml, 20ml), and different cutting methods(with cotton, without cotton) were evaluated. METHOD: Twenty ampules were randomly assigned in each group. Three slides containing glass particles for each ampule were made and counted under a microscope by 3 study blind persons. RESULT: The number of glass particle contamination is much less when using a filter rather than without a filter. The number of glass particle contamination is much less when using a 25G needle rather than on 18G needle. The number of glass particle contamination is much less when using 2ml ampules rather than 20ml ampules. The number of glass particle contamination is much less when using cotton rather than without cotton. CONCLUSION: It was shown that using a filter, a small size needle, smaller sized ampules and using cotton when cutting the ampule will decrease the risk of parenteral injection of glass particles.

OBJECTIVE: Association between home environment and the behavioral and neurocognitive development of children from a community childcare center for low-income families was examined (aged 6 to 12 years, n=155). METHODS: The parents performed a questionnaire on home environment (K-HOME-Q) to assess home environment including parenting attitude and the Child Behavior Checklist (K-CBCL). The children performed the Wechsler Intelligence (IQ) Scale, Stroop interference test (Stroop), word fluency test (WF), and design fluency test (DF) to assess their neurocognitive development. RESULTS: ‘Nurturing of Development’ and ‘Variety of Language Interaction’ scores from the K-HOME-Q, were inversely associated with total behavior problems, externalization, rule-breaking, and aggressive behavior subscales of K-CBCL, and ‘Emotional atmosphere’ and ‘Tolerance toward the child’ scores showed inverse associations with the total behavior problems, rule-breaking, aggressive behavior, and withdrawn/depressed subscales. Despite economic hardship, the mean scores of the neurocognitive tests were comparable to the average level of Korean children’s normative sample. However, ‘Nurturing of Development’ and ‘Tolerance toward the Child’ score of K-HOME-Q were associated with better executive function (IQ, WF, DF). CONCLUSION: These results suggest that parental stimulation of development and tolerant parenting attitude may offer protection against the negative effects of suboptimal economic environment on children’s behavior and neurocognitive development.

Platelet-rich plasma (PRP) contains growth factors that promote tissue regeneration. Previously, we showed that heparin-conjugated fibrin (HCF) exerts the sustained release of growth factors with affinity for heparin. Here, we hypothesize that treatment of skin wound with a mixture of PRP and HCF exerts sustained release of several growth factors contained in PRP and promotes skin wound healing. The release of fibroblast growth factor 2, platelet-derived growth factor-BB, and vascular endothelial growth factor contained in PRP from HCF was sustained for a longer period than those from PRP, calcium-activated PRP (C-PRP), or a mixture of fibrin and PRP (F-PRP). Treatment of full-thickness skin wounds in mice with HCF-PRP resulted in much faster wound closure as well as dermal and epidermal regeneration at day 12 compared to treatment with either C-PRP or F-PRP. Enhanced skin regeneration observed in HCF-PRP group may have been at least partially due to enhanced angiogenesis in the wound beds. Therefore, this method could be useful for skin wound treatment.

OBJECTIVES: In this study, we performed a preliminary investigation for establishing guidelines for the usage of smartphones in children and adolescents. METHODS: From March 2014 to August 2014, 182 board-certified psychiatrists were asked to participate in the survey ; 121 participants completed the questionnaire. The questionnaire was developed by the authors, mainly the Public Relations Committee of the Korean Academy of Child and Adolescent Psychiatry. It evaluates psychiatrists' opinions on the use of smartphones in children and adolescents. In addition, psychiatrists' attitudes towards their own usage of smartphones were assessed in order to determine the impact on their opinion towards the children's usage. RESULTS: Psychiatrists have recommended various opinions as the appropriate age to own a smartphone for the first time. Mean age recommended by psychiatrists is grade 7.7. One-hundred participants (82.6%) agreed to the age limit to own a smartphone for the first time. In addition all participants agreed to the necessity of a time limit in children and adolescents. Psychiatrists (17.4%) who disagree on the age limit in children considered the smartphone more useful by themselves compared to psychiatrists who agreed on the age limit. CONCLUSION: Most psychiatrists have recommended that an appropriate limit for smartphone usage in children and adolescents is needed.

Most preschool children in Korea attend kindergarten (KG) or a child care center (CCC). CCCs, which focus on caring for the child, belong to the ministry of health and welfare. On the other hand, KGs are responsible for education, and belong to the ministry of education, science and technology. In order to resolve the decline in population due to low birthrates, the government is expanding the free child care and education policies. CCCs and KGs are combined together to form the 'NURI curriculum' and supporting funds have been increased in both governmental departments. In addition, economic support is provided for homeschooling households. Because this is a nationwide policy and applies to every single household, thorough preparation regarding the effect and side effects must be made. This policy is currently being implemented, and as child and adolescent psychiatrists, great consideration should be given to the influence on the population. Therefore, the Korean Academy of Child and Adolescent Psychiatry intends to investigate the effects and problems of the nationwide policy by analyzing the current condition of Korea's free child care and education and foreign policies. In the current paper, we reviewed the developmental process of Korea's free child care and education policy, as well as suggested future directions.

In order to resolve the decline in population due to low birthrates, the South Korean government is expanding its free child care policies with an increased budget. In anticipating the effects and problems of our system, it will be worthy of attention to refer to the child care systems of other countries. In this paper, we reviewed the past and present policies and the current situation of the child care system in North Korea. North Korea started its free child care system earlier than that of South Korea, for the purpose of utilizing the women's labor force and rearing children to be revolutionary men of Juche type (Kimilsungism), in order to construct a communistic society. 'Child Care Education Law', which is the legal foundation of the child care system, regulates institutions for nursery schools and kindergarten and informs people that the country is responsible for support of child care. Despite their interest and progress in both quantity and quality in the child care system until the 1980s, the free child care system was partially disrupted, and discrepancies between ideology and actual situation were revealed due to economic difficulties from the 1990s. Because people's survival and physical health have been threatened, it is barely possible to find any study investigating the effect of institutional child care from early childhood and the instillation of unique ideology by group education from the preschool period on mental health.

Polyethylene glycol solutions have been usually available for clinical use since 1980 and been considered a standard method of bowel preparations for colonoscopy. There have been many reports about minor complications such as nausea and bloating associated with their use, which are frequently occurred. After ingestion of polyethylene glycol, vomiting occurrs less frequently but it can make major complication such as Mallory-Weiss syndrome and aspiration pneumonia. We have reported here two cases of Mallory-Weiss syndrome, which were occurred after ingestion of polyethylene glycol solution for colonoscopy.

In an effort to expand working opportunities for women and encourage childbirth, the government of Korea introduced the free infant care policy in 2013. This policy, however, was controversial with regard to issues, such as budget shortages and dissatisfaction based on socioeconomic status. In addition, the lack of evidence-based data regarding adequate age criteria for the entry of children into childcare facilities was noted as a challenge. As child development professionals who are concerned with mental health issues, we investigated the influence and challenges of the free infant care policy with regard to infant mental health. In this review, we examined the policies enacted by developed countries, such as the United Kingdom (UK), and compared them with those in Korea. The childcare systems in Korea and the UK differ historically and socially, but show some similarities, such as maternal responsibility for parenting and household issues. Like Korea, the need for UK childcare facilities increased in the 1990's in response to market recovery and associated increase in female employment. Among the new policies in the UK, the Sure Start program has begun to provide integrated services for infants, particularly to those 0-4 years of age, who are vulnerable to social exclusion. Similar to the Dream Start program in Korea, it has been successful in providing family-related services, resulting in improvements in problematic behaviors of children, enhanced parenting skills, and decreased rates of severely injured children.

Objectives: Adult attention-deficit/hyperactivity disorder (ADHD) is an important mental health problem that needs resolution, especially considering the high rates of ADHD continuation from childhood to adolescence/adulthood and the high prevalence of ADHD in adults. Adults with ADHD have lifelong negative impacts and require close monitoring with long-term follow-up. Hence, the establishment of a Korean practice parameter for adult ADHD is necessary to minimize discontinuation of treatment and enable information sharing among Korean mental health professionals. Methods: The Korean practice parameter was developed using an evidence-based approach consisting of expert consensus survey coupled with literature review. Results: According to the expert consensus survey, the most commonly used diagnostic methods were clinical psychiatric interview (20.66%) and self-report scales (19.25%) followed by attention (14.71%) and psychological tests (14.24%). Key evaluation instruments currently available in Korea are the World Health Organization Adult ADHD Self-Report Rating Scale, Korean Adult ADHD Rating Scale, Diagnostic Interview for ADHD in Adults, Barkley Deficits in Executive Functioning Scale for adults, Comprehensive Attention Test, Conners’ Continuous Performance Test, and the subtests of Wechsler Adult Intelligence Scale, Digit Span and Letter-Number Sequencing. Although pharmacotherapy is recommended as the first-line of treatment for adult ADHD, we recommend that it be followed by a multimodal and multidisciplinary approach including psychoeducation, pharmacotherapy, cognitive behavior therapy and coaching. Conclusion The Korean practice parameter introduces not only general information for the diagnosis and treatment of adult ADHD on a global scale, but also the process of diagnosis and treatment options tailored to the Korean population.
