As smart devices become more widespread, young children can easily access these devices and become proficient users. The purpose of this study is to examine the contributions of mothers’ perceptions toward smart devices and parenting stress regarding their children’s overindulgence in smart devices. Furthermore, this study explored the mediating role of parents’ co-use of smart devices among these relationships. Our data were collected from 262 Korean mothers who had a child aged less than 36 months old who have ever used smart devices. Results from a structural equation modeling analysis indicated that maternal parenting stress was directly related to children’s overindulgence. Moreover, mothers’ perceptions toward smart devices were indirectly related to children’s overindulgence through co-use. In other words, mothers who have positive perceptions of smart devices are more likely to let their child use smart devices alone, which in turn is associated with children’s overindulgence in smart devices. These findings suggest the importance of parental education about the consequences of smart devices use for young children and the roles of parents when their child uses such a devices. 본 연구는 36개월 미만의 영유아기 자녀를 둔 어머니의 스마트기기에 대한 인식, 양육스트레스, 스마트기기 함께 사용여부 및 영유아의 스마트기기 과몰입 간의 구조적 관계를 살펴보고자 하였다. 구체적으로 어머니의 스마트기기에 대한 인식 및 양육스트레스가 영유아의 스마트기기 과몰입에 미치는 직접적 영향과 스마트기기 함께 사용여부를 통해 미치는 간접적 영향을 알아보고자 하였다. 이를 위해 서울 및 대전 지역에 위치한 어린이집 18곳에 다니고 있는 36개월 미만의 자녀를 둔 262명의 어머니를 대상으로 자료를 수집하여 분석하였다. 주요 결과를 살펴보면, 어머니의 양육스트레스가 영유아의 스마트기기 과몰입에 유의한 영향을 미치는 것으로 나타났다. 또한 스마트기기 사용에 대한 어머니의 인식은 스마트기기 함께 사용여부를 매개로 영유아의 스마트기기 과몰입에 유의한 영향을 미쳤다. 즉 스마트기기 사용이 영유아의 발달에 긍정적일 것이라고 인식하는 어머니일수록 스마트기기를 자녀 혼자 사용하게 하며, 이는 영유아의 스마트기기 과몰입으로 이어졌다. 이러한 연구 결과는 스마트기기 사용이 저 연령화 되고 있는 오늘날, 영유아의 스마트기기 과몰입 예방을 위한 부모의 역할을 제시하였다는 점에서 의의가 있다.

Objective: This study was conducted to investigate the preventive effect of herbal medicines on restenosis after percutaneous coronary intervention (PCI) by reviewing randomized controlled trials (RCTs). Methods: RCTs were searched for herbal medicine treatment after PCI using eight online databases (PubMed, CNKI, Wanfang, J-STAGE, OASIS, ScienceON, KTKP, and KISS). Studies that confirmed restenosis through coronary angiography at follow-up were selected according to the inclusion and exclusion criteria. The primary outcome was the restenosis rate, and the secondary outcome was the angina recurrence rate. Data were extracted from the final selected studies according to the research methodology and then analyzed with Review Manager 5.4.1. Study quality was assessed using Cochrane's risk-of-bias (RoB) tool. Results: Of the 252 papers obtained through the primary search, nine studies that met the selection criteria were finally selected. In these nine studies, herbal medicine combined with western medicine was used for the experimental group, and western medicine treatment was used alone for the control group. The meta-analysis result revealed that the restenosis rate and angina recurrence rate were significantly lower in the experimental group than in the control group (RR=0.34, 95% CI: 0.22-0.53, p<0.00001, I²=0% and RR=0.47, 95% CI: 0.29-0.78, p=0.004, I²=0%, respectively). Furthermore, the quality of studies assessed by Cochrane's RoB was low. Conclusions: This study showed that the combined treatment of herbal medicine and western medicine was effective in preventing restenosis and angina after PCI. As the number of papers included in this study was small, a large number of high-quality clinical studies should be considered in the future.

납사분해 공정 내 열 교환 네트워크 경제적-환경영향 평가

Petrochemical is an energy consuming industry that consumes about 30% of total industrial energy consumption and is a representative carbon dioxide (CO₂) emission source. Among them, the Naphtha Cracking Center (NCC), which produces ethylene, propylene, propane and mixed C4, consumes large amounts of energy and emits significant amounts of CO₂. For this reason, an integrated techno economic- environmental impact assessment aimed at reducing energy consumption and environmental impact factors is necessary to ensure efficiency in terms of economics and environment. This study aims to analyze the efficiency of the heat exchanger network used in the existing NCC base on the pinch analysis and select an improvement plan that can reduced energy consumption. In order to reduces the utility consumption in the process, an optimal heat exchanger network considering the high-temperature and low-temperature stream was derived, and the economic evaluation was conducted by considering the trade-off between the reduction in utility consumption and the increase in heat exchanger installation cost. In addition, an environmental impact assessment was conducted on the reduced CO₂ emission in consideration of the environmental aspect, and the economic environmental impact assessment used the payback period to recover the invested funds to come up with an energy saving plan that can be applied based on the actual process. As a result of considering the economic-environmental impact assessment, when the environmental impact assessment was not considered, it was 4.29 months, 3.21 months, and 3.39 months for each case, and when considering the environmental impact assessment, it was 4.24 months, 3.17 months, and 3.35 months for each case. These results appeared equally both when the environmental impact assessment was not include and when it was include. In addition, a sensitivity analysis was conducted for each case to determine how important factors affect the payback period. As a result of the sensitivity analysis, the cost of the heat exchanger was identified as a major factor influencing the overall cost.

Objectives : The purpose of this study is to investigate on the application of the yttrium aluminum garnet (YAG) lasers for acupoints irradiation. Methods : We conducted a systematic search for peer-reviewed studies published from inception to November 2023, in the following electronic databases: PubMed, Scopus, and Web of Science in English, Science ON, Oriental Medicine Advanced Searching Integrated System (OASIS) and Research Information Sharing Service (RISS) in Korean, and China National Knowledge Infrastructure (CNKI) and Wanfang in Chinese, and Japan Science Technology Information Aggregator, Electronic (J-STAGE) and Citation Information by NII (CiNii) in Japanese. Inclusion criteria were original articles including clinical and experimental studies related with YAG lasers for acupoints including Ashi or meridian sinews. Results : Among the 8 selected studies, there were 7 studies on human subjects and 1 study on animals, 7 studies on Nd:YAG (1,064 nm) laser, and 1 study on Er:YAG (2,940 nm) laser. A total of 16 acupoints were used, 15 of which were in the face and 1 of which was located in the foot. In addition, there were two studies using Ashi. 4 studies looked at the effect of pain relief, 2 studies looked at safety, 1 study looked at changes in blood flow, and 1 study looked at the effect of skin care. There were no reported adverse events, and the YAG laser was confirmed to be safe and effective in pain relief, beautifying the skin, and increasing blood flow. Conclusions : We suggest that high intensity YAG lasers can be applied to laser acupuncture or laser moxibustion. YAG lasers are considered to be worth using for various clinical indications of Korean medicine because of photobiomodulation effects, analgesic action, and deep penetration depth. Further scientific research and clinical evidences should be warranted.
