  • The emissions trading system, introduced to reduce greenhouse gas emissions, experienced a sharp increase in emission allowance prices during the second plan period (2018-2020), which led to an increase in the demand for smooth supply and demand of emission allowances, while suppliers anticipating a shortage of emission allowances in the future did not participate in trading. Therefore, the authority temporarily revised the guidelines to ensure that the amount of allowances carried forward is proportional to the trading volume as a market stabilization measure. Through an optimization process using a dynamic nonlinear mathematical model, this paper analyzes the impact of the government's intervention on the carryover policy on GHG emission reductions and emission allowance market prices. According to the simulation analysis results, banking regulations could cause a decline in prices during the regulation period, even though the initial policy was predicted to be adopted.

  • Recently, as various cases of using deep learning in the health-care field are increasing, functions such as electrocardiogram examination and body composition analysis through wearable device can be provided to provide rational decision-making and a process tailored to the individual. In order to utilize deep learning, it it most important to secure refined data, and this data is being made through human intervention or unsupervised learning. In this paper, we propose a model that conducts unsupervised learning by clusters according to gender and age using human body data such as chest and waist circumferences, which are easy to measure, and classifies them with CNN. For data, the 7th human body data provided by Korean Agency for Technology and Standards was used. Through this, it it thought that it can be applied to various application cases such as personalized body shape management service and obesity analysis.

  • This study examined the mediating effect of social isolation on the life satisfaction among lowincome older adults. The purpose of this study was to find out isolated older adults' social isolation rate and mediating effect of sense of community by community dwelling older adults with loweconomic status. This study used the Gijang Welfare Network study(2009). The sample consisted 256 older adults 65 and older residing in Busan(Gijang). As statistical method, correlation analysis and structural equation model used in this paper. The results of this study suggested some practical implications in reducing social isolation for older adults with low economic status. We need to emphasize social relations and social participations as well as outreach program for high-risk elderly of social isolation. In addition, Findings suggested that community based interventions should be provided to protect older people, especially poor elderly from social isolation.

  • In order to explore the impact of gender in the effects of age, temperament, and parenting on preschoolers' psychosocial problems, 339 preschoolers, 3-5 year old, were assessed using parent report measures of externalizing and internalizing behavior problems, temperament, and parenting. The results of ANOVA and hierarchical regression analyses are as follows. First, the main effects of age and gender for externalizing problems and the interaction effect of age and gender for internalizing problems were significant. Second, the important predictors of preschoolers' internalizing and externalizing problems were different by gender. In boys, Novelty Seeking(NS), Harm Avoidance(HA), and hostile parenting significantly predicted both problems. In girls, NS, HA, and warm parenting significantly predicted both problems. In addition, girls were more strongly influenced by parenting whereas boys were more influenced by their temperaments. The results of this study highlight some important suggestions for prevention strategies for preschoolers' behavioral problems. The implications and limitations of this study were further discussed.

  • The purpose of this study was to examine the mediating effects of paranoid tendency and social isolation in relationship between covert narcissism and Tajin Kyofusho(TKS). We administered self-report questionnaires to 334(163 male, 171 female) undergraduate students. Path analysis conducted using structural equation modeling. Path analysis indicated that the overall model fitted the data well. Analysis showed that paranoid tendency and social isolation sequentially mediated relationship between covert narcissism and TKS. The finding suggest that we could focus on covert narcissistic personality, paranoid cognitive process, and behavioral social isolation to understand and intervene TKS.

  • The purpose of this study is to examine factors affecting knowledge about cardiopulmonary resuscitation of older persons. For the purpose of the study, 2022 Social Survey conducted by Statistics Korea was utilized and 8,862 older persons aged over 65 years old were analyzed. Results of the analyses showed that individual resources and social resources of older persons had significant effects on knowledge about cardiopulmonary resuscitation. Regarding individual resources, a higher level of education, a higher level of income, a higher level of subjective health status, and a higher level of cognitive function increased the level of knowledge about cardiopulmonary resuscitation of older persons. Regarding social resources, having a spouse and a higher level of satisfaction of relationship with children increased the level of knowledge about cardiopulmonary resuscitation of older persons. Based on results of this study, various interventions are needed to improve the level of knowledge about cardiopulmonary resuscitation among vulnerable older groups with regard to the coping knowledge with emergency situation.

  • The research purpose outlined emphasizes the growing need for systematic and professional disaster education for nurses and nursing students, driven by the increasing occurrence of natural and large-scale social disasters. The study, a systematic literature review, analyzed the effects of educational interventions in disaster education targeting this demographic. The research method involved a literature search in major Korean databases using keywords related to disaster, education programs, and simulations. The findings highlighted that most programs utilized a combination of theoretical lectures, simulations, and debriefing methods, with intervention times ranging from less than 2 hours to between 40 and 56 hours. The primary outcomes measured were disaster nursing preparedness and performance abilities, with the programs showing positive effects on variables such as disaster nursing readiness, performance ability, attitude, knowledge, awareness, learning self-efficacy, practice satisfaction, and confidence in disaster nursing. The study suggests the importance of designing programs that offer participants realistic learning experiences through diverse intervention times and methods and emphasizes the need to verify the effectiveness of these programs.

  • This study was conducted to evaluate the quality of meta-analysis of social work in South Korea using the Assessment of Multiple Systematic Review (AMSTAR). Electronic databases including the Korean Studies Information Service System (KISS), DBpia, and RISS4U were searched for 'meta-analysis', 'social work', and 'social welfare' from 2000 to December 2015, and 42 meta-analysis studies were included. Data were analyzed using descriptive statistics, t-tests, and ANOVA. The mean score for AMSTAR evaluation was $4.766{\pm}1.66$, while 19 studies (45.2%) were classified at the low-quality level, and 22 (52.4%) were at the moderate-quality level. The scores of quality assessment were analyzed by publication year, participants, number of studies included, number of DB, reporting study quality, extraction diagram and topics. The findings indicated that the following changes should be implemented to improve the quality and reliability of meta-analysis results in social work research: 1) common reporting guidelines should be provided for the social work field, 2) quality analyses of each study should be conducted to achieve a high level of evidence of effectiveness of social work interventions, 3) the characteristics of the included studies should be provided, and 4) a consensus and procedure based on at least two independent data extractors should be reported.

  • The optimized derived intervention levels for animal products were evaluated based on cost-benefit analysis. From these results, the radionuclide concentrations in animal feedstuffs for use were derived. It was shown that radionuclide concentrations in animal feedstuffs for use depend strongly on animal products, radionuclides and feeding period (period from the starting time to be led with contaminated feedstuffs to production time of animal products). In case of feedstuffs contaminated with long-lived radionuclides ($^{l37}Cs,\;^{90}Sr$), the feedstuffs with lower contamination should be supplied to animals with increase of feeding period due to the bioaccumulation of radionuclides. While, in case of feedstuffs contaminated with short-lived radionuclides ($^{131}I$), the feeding of higher contaminated feedstuffs was possible with increase of feeding period due to radionuclide decay. It was shown that $^{137}Cs$ concentration in animal feedstuffs lot use was lower than $^{90}Sr$ concentration. It is primarily, due to the higher feed-animal product transfer factor of $^{137}Cs$.

  • 1997년 시장개방 이후 할인점을 중심으로 한 대형유통점은 급성장한 반면, 중소유통점은 계속 쇠퇴하고 있다. 대형유통점이 대도시에 이어 지방중소도시로 확대되면서 중소유통점은 대형유통점이 자신의 생존을 가장 크게 위협하고 있는 것으로 인식하고 있다. 이로 인해 중소유통점과 대형유통점간의 갈등이 확산되고 있는 실정이다. 갈등이 확산되면서 일부 지자체의 경우 이미 조례로 대형유통점에 대한 규제를 강화하였으며, 일부 의원들에 의해 대형 유통점에 대한 규제를 주 내용으로 하는 입법발의가 되고 있다. 중소유통점이 정부와 지자체에 요구하는 것은 크게 두 가지이다. 하나는 중소유통업을 살리기 위해 중소유통점에 대한 지원을 강화해 달라는 것이며, 또 다른 하나는 대형유통점에 대한 규제를 강화해 달라는 것이다. 반면, 대형유통점은 유통산업 전체의 건전한 발전과 선진화, 글로벌화를 위해 대형유통점에 대한 규제를 오히려 완화해 달라고 요구하고 있다. 대형유통점은 중소유통점의 경쟁력 강화를 목적으로 하는 정부나 지자체의 지원에는 반대하고 있지 않다. 정부와 지자체가 고려할 수 있는 정책대안은 크게 네 가지이다. 첫 번째 방안은 자유경쟁의 원리에 의해 정부가 시장에 개입하지 않는 것이다. 이 경우, 경쟁력이 약한 중소유통점은 계속 쇠퇴할 것이며 갈등이 심화되고 정부와 지자체에 대한 사회정치적 비난이 커질 우려가 있다. 두 번째 방안은 중소유통점의 경쟁력 강화를 위해 정부와 지자체가 이들에 대한 지원을 강화하는 것이다. 개별 중소유통점의 경영혁신 노력과 중소유통점간의 연대노력을 행 재정적으로 지원하는 것이 주된 내용이다. 중소유통사업자의 경영능력 배양을 목적으로 한 교육지원, 마케팅능력 제고, 협업화, 조직화, 정보화의 촉진, 공동사업에 대한 지원이 이에 해당될 것이다. 현재 정부와 다수의 지자체가 취하고 있는 방안이며 네 가지 대안 중 가장 합리적인 것으로 평가되고 있다. 세 번째 방안은 대형유통점과 중소유통점간의 상생협력을 정부와 지자체가 유도하는 것이다. 경쟁관계에 있는 두 당사자 간의 상생협력을 모색하는 것은 모양새는 아름답지만 실효성이 낮은 것이 문제이다. 전시성, 일회성 사업으로 끝나지 않도록 하여야 할 것이다. 네 번째 방안은, 정부와 지자체가 대형유통점에 대한 규제를 강화하는 것이다. 먼저, 대형유통점의 불공정거래행위에 대한 감시감독과 처벌을 강화하는 것은 당연한 것이다. 그러나 정부가 아닌 지자체가 이를 주도하기는 사실 어려움이 있다. 그리고 대형유통점이 영업행위를 영업시간제한에서부터 출점제한에 이르기까지 규제하는 건은 심사숙고하여야 한다. 대형유통점이 국가경제 및 지역사회에 미치는 영향이 부정적인가 긍정적인가에 대해 국내외 학계와 업계에서 여전히 많은 논란이 있기 때문이다. 정부와 지자체에 의한 시장개입은 반드시 필요한 경우에 한해 합당한 방법에 의해 이루어져야 한다. 대형유통점에 대한 규제는 지역사회에 미치는 영향을 다면적으로 평가한 결과에 근거하여 이루어져야 할 것이다. 대부분의 지자체는 체계적인 평가시스템과 객관적인 통계 자료를 갖고 있지 못한 실정이다. 향후 가장 시급한 과제는 시장개방 이후 지난 10년간 대형유통점이 지역사회에 미친 영향에 관한 광범위한 통계자료를 수집하고 이를 체계적으로 분석하여 정책방향을 올바르게 설정하는 것이라 할 수 있다.
