강수정(Sujeong Kang) 한국아동학회 2021 아동학회지 Vol.42 No.2

Objectives: The purpose of this study was to examine longitudinal effects of father involvement in child-reaering during early childhood on first graders’ school adjustment, focusing on the mediating role of executive function difficulties. By doing so, the present study attempted to investigate the importance of fathers’ involvement in childcare during early childhood. Methods: This study used the 4th, 5th, and 8th data sets from the Panel Study on Korean Children. A total of 1,711 data were analyzed. Descriptive statistics analysis, Pearson correlation analysis, structural equation modeling analysis, and bootstrapping were conducted. Results: Fathers’ rearing involvement during early childhood was found to have a positive effect on first graders’ school adjustment by reducing levels in the children’s executive function difficulties, with socioeconomic status and children’s gender being considered as a confounder. However, fathers’ rearing involvement during early childhood did not have a direct effect on first graders’ school adjustment. Conclusion: The present study suggests that fathers’ rearing involvement in early childhood is important for first graders’ cognitive development and school adjustment in the long term. This study is meaningful in that it did not simply reveal the longitudinal influences of fathers’ rearing involvement on children’s elementary school adjustment, but also explained these influences through the development of children’s executive skills.

강수정(Kang, Sujeong),이지연(Lee, Jeeyon),장진이(Jang, Jinyi) 한국열린교육학회 2014 열린교육연구 Vol.22 No.1

본 연구는 교사를 대상으로 교수 몰입, 감사 성향, 대인관계 유능성이 행복감에 미치는 영향을 살피고, 교수 몰입의 행복에 미치는 영향력이 개인차 변인인 감사 성향과 대인관계 유능성 수준에 따라 차이가 있는지를 탐색하고자 하였다. 이를 위하여 교수 몰입이 행복에 영향을 미치는 과정에서 감사 성향과 대인관계 유능성의 조절 효과를 가정하는 연구 모형을 설정하여 검증하고자 하였다. 위계적 회귀분석을 실시한 결과, 감사 성향의 조절 효과는 유의미하였으나, 대인관계 유능성의 조절 효과는 유의미하지 않았다. 즉, 교수 몰입이 교사의 행복감에 미치는 영향력은 교사 개인의 감사 성향 수준에 따라 차이가 있었는데, 감사 성향 수준이 낮은 교사들의 교수 몰입은 감사 성향 수준이 높은 교사들의 교수 몰입보다 행복감을 더 촉진시키는 것으로 나타났다. 이러한 연구 결과를 바탕으로 연구 결과의 제한점과 추후 연구에 대한 함의를 기술하고, 교사 연수나 교사 자문 및 상담적 개입에서 감사 성향에 대한 평가와 이를 훈련시킬 수 있는 프로그램의 개발과 개입 전략의 모색이 필요함을 강조하였다. The purpose of this study was to examine the moderating effects of gratitude disposition and interpersonal competence on the relationship between teachers's teaching flow and happiness. In order to achieve this goal, 232 male and female teachers in Seoul and Metropolitan area were surveyed. The data was submitted to SPSS/WIN 18.0 statistics program to test mutiple regression analysis and hierarchical regression analysis. The results are as follows. Firstly, teachers's teaching flow, gratitude disposition and interpersonal competence significantly influenced on their happiness. Secondly, there was a significant moderating effect of gratitude disposition on the relationship between teachers's teaching flow and happiness. Thirdly, the moderating effect of interpersonal competence wasn't seen as significant. These results implied that it's necessary to develop the programs and intervention strategies for promoting teachers's gratitude disposition. The implications for future research and teacher training programs were discussed.

설명하기가 유아의 실행기능에 미치는 영향: 설명 대상의 상호작용 수준별 비교

강수정(Sujeong Kang),최나야(Naya Choi) 인지발달중재학회 2021 인지발달중재학회지 Vol.12 No.2

연구목적: 본 연구는 설명하기가 유아의 실행기능에 미치는 영향을 살펴보았으며, 설명 대상과의 상호작용 수준에 따라 집단을 나누어 그 영향력을 비교하였다. 이때 실행기능의 행동 측정치와 신경 측정치를 함께 고려해, 설명 대상과의 상호작용 수준에 따른 행동 변화 시 어떠한 뇌 활성화 변화가 동반되는지 살펴보았다. 연구방법: 5세 유아 55명을 대상으로 실행기능을 측정하기 위한 사전검사로 카드분류과제를 실시하였다. 이후 유아를 세 집단으로 나누어 설명 대상과의 상호작용 수준에 따라 서로 다른 설명하기 경험을 하도록 하였다. 마지막으로 사후검사로 카드분류과제를 다시 한번 수행하였다. 카드분류과제 수행 시 정답률을 확인했으며, Near-infrared spectroscopy (NIRS)를 활용해 전전두엽의 활성화 정도를 측정하였다. 연구결과: 유아에게 카드분류과제에 대해 설명하도록 했을 때, 능동적 대상에게 설명한 경우가 상호작용이 없었던 경우에 비해 카드분류과제 사후검사에서 정답률이 더 높게 나타났다. 전전두엽의 활성화 정도를 분석해본 결과, 능동적 대상에게 설명한 유아가 수동적 대상에게 설명한 유아 및 상호작용을 하지 않은 유아에 비해 좌측 측면의 활성화 정도가 더 높게 나타났다. 결론: 이 연구는 설명 대상과의 상호작용 수준에 따라 설명하기가 유아의 실행기능에 미치는 영향을 비교 함으로써, 아동의 인지발달에서 언어와 사회적 상호작용의 역할을 강조한 사회문화적 구성주의 이론을 실증적으로 검증하였다. 또한 유아가 설명할 때 부모나 교사와 같은 대상이 능동적으로 반응해주는 것이 유아의 실행기능에 긍정적 영향을 줄 수 있다는 실용적 함의를 제공하였다. Objective: The purpose of this study was to examine the effect of interaction types during explanation process on young children’s executive function. Methods: Fifty five 5-year-old children performed the Dimensional Change Card Sorting (DCCS) task for the pre-test. Then, for the intervention, children were assigned to one of three experimental conditions: 1) no-interaction, 2) passive-interaction, and 3) active-interaction. In the post-test, children once again performed the DCCS task. When children performed the DCCS task, a percentage of the correct answers and neural activation levels of the lateral prefrontal cortex were recorded using E-prime 2.0 and Near-infrared spectroscopy (NIRS). Results: Children in the active-interaction condition demonstrated a greater percentage of correct answers than those in the no-interaction condition. Also, children in the active-interaction condition showed higher levels of neural activation in the left LPFC than those of passive-interaction and no-interaction conditions. Conclusions: This study empirically demonstrates the sociocultural approach that emphasizes the role of language and social interaction in children’s cognitive development. This study also provides implications for parents and educators that the role of an active listener can be effective in supporting young children’s cognitive development.

강수정(Sujeong Kang),홍예지(Yea-Ji Hong),최나야(Naya Choi),이강이(Kangyi Lee) 한국아동학회 2017 아동학회지 Vol.38 No.6

Objective: The purpose of this study was to investigate the relationship between breastfeeding duration and preschooler problem behavior, focusing on the mediating role of cognitive development. Methods: The data came from the Panel Study on Korean Children. The study sample included 926 participants. The statistical methods for the data analyses included descriptive statistics analysis, Pearson correlation analysis, partial correlation analysis, regression analysis, and the Sobel test. Results: Breastfeeding duration predicted preschooler cognitive development, internalizing problems, and externalizing problems after adjusting for potential confounding factors (i.e., sex, SES, temperament, and parenting style). Further, cognitive development fully mediated the relationship between breastfeeding duration and externalizing problems at age 5 years. Conclusion: The results from the current study support the hypothesis that breastfeeding predicts preschooler cognitive development and problem behavior after adjusting for confounding factors. Further, the relationship between breastfeeding duration and externalizing problems was explained via cognitive development. Based on these results, we recommend the practice of breastfeeding for healthy early childhood development.

A Sociolinguistic Study on Korean Names of Immigrants in Korean Society

Miyeong Kang,Sujeong Kim,Mijeong Kang 한국중원언어학회 2022 언어학연구 Vol.- No.65

The purpose of this study is to find out factors that immigrants settling in Korean society decide their names and the social value of their names. In order to accomplish this, an online survey was conducted from August 1 to 5, 2022 to collect a total of 80 valid questionnaires, and a phone interview was conducted to complement its shortcomings. Results of the study are summarized as follows. First, as a result of examining the immigrants’ names by word types, they were found in the order of Chinese character words, loanwords, and mixed words. Second, the meanings immigrants wanted to include in their names was in the order of appearances, attitudes of life, ability and success, and luck and grace. Third, those who named the immigrants appeared in the order of parents, spouses, myself, or parents-in-law, acquaintances, relatives and grandparents. This study can be said to be of great significance in that it is possible to grasp one aspect of the language culture that immigrants are building in their lives by examining sociolinguistic characteristics of their names in Korean society.

Screening of Kimchi-derived Lactic Acid Bacteria for Prevention of Muscle Loss

Juyeon Lee,Minkyoung Kang,Sujeong Lee,Minji Kang,Sujeong Hwang,Jiseon Yoo,Bohyun Yun,Sangnam Oh 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Sarcopenia is a chronic disease characterized by the progressive loss of skeletal muscle mass in aged. Recent reports showed probiotics could affect the progression of muscle loss by modulating gut microbiome. Kimchi confers potential probiotics properties containing lactic acid bacteria (LAB). The objective of this study was to evaluate the probiotic properties of LAB isolated from Kimchi and investigate the effect of probiotics on preventing sarcopenia. A total of 255 strains of LAB were isolated from 12 types of Kimchi, and 53 strains were finally selected by resistance to artificial gastric juice, bile salts, and ability of attachment to human intestinal epithelial cells. C.elegans mutant (PD4251) expressing green fluorescent protein myo-3 localized in body wall and vulval muscle was adopted to evaluate the prevention from muscle loss. Four strains (LFR20-010, LFR20-030, LFR20-033, LFR20-040) fed worms showed the higher GFP expression than the standard bacterial source fed. RT-qPCR analysis showed that LFR20-030, LFR20-033 upregulated muscle-related genes in worms. Present study suggests that new Lactobacillus spp. separated from kimchi may delay the progress of sarcopenia.

Vernalization Regulates Flowering Genes and Modulates Glucosinolates Biosynthesis in Chinese Cabbage

Kang Hajeong,앗지 바스코로,Park Minkyu,Kim Jin A.,Lee Sang Woo,Moon Heewon,Choi Dasom,Kim Sujeong,Kim Dong-Hwan 한국식물학회 2022 Journal of Plant Biology Vol.65 No.2

Long-term cold exposure, such as that in winter, termed vernalization, provides flowering competence in many winter-annual, biennial, and perennial plants, including Brassicaceae family plants. Vernalization results in significant phenotypic and physiological changes, including floral transition in plants, which are accompanied by transcriptomic changes. To date, studies attempting to determine the molecular processes underpinning vernalization responses, especially flowering, have mainly focused on model Arabidopsis thaliana plants. To better understand the vernalization response in Chinese cabbage (Brassica rapa ssp. pekinensis), we investigated transcriptomic changes occurring during vernalization. We found that thousands of genes were dynamically modulated by both short-term (cold acclimation) and long-term cold (vernalization) exposure, compared with non-vernalized samples. Further, 15 hierarchical clusters of differentially expressed genes were identified based on their distinct expression patterns. A gene ontology analysis using upregulated and downregulated genes during the vernalization time course revealed that metabolic and physiological changes also occur during vernalization. Particularly, we noticed that vernalization upregulated the transcription of glucosinolate (GSL) pathway genes and the levels of corresponding GSL compounds in Chinese cabbage. Overall, vernalization triggers dynamic transcriptomic alterations to not only genes related to floral transition but also genes involved in GSL metabolism in Chinese cabbage plants.

Intravenous Fluid Selection for Unruptured Intracranial Aneurysm Clipping : Balanced Crystalloid versus Normal Saline

Kang, Jian,Song, Young Joo,Jeon, Sujeong,Lee, Junghwa,Lee, Eunsook,Lee, Ju-Yeun,Lee, Euni,Bang, Jae Seung,Lee, Si Un,Han, Moon-Ku,Oh, Chang Wan,Kim, Tackeun The Korean Neurosurgical Society 2021 Journal of Korean neurosurgical society Vol.64 No.4

Objective : While balanced crystalloid (BC) could be a relevant fluid regimen with buffer system compared with normal saline (NS), there have been no studies on the optimal fluid for surgery of an unruptured intracranial aneurysm (UIA). This study aimed to compare the effects of fluid regimens between NS and BC on the metabolic and clinical outcomes of patients who underwent surgery for UIA. Methods : This study was designed as a propensity score matched retrospective comparative study and included adult patients who underwent UIA clipping. Patient groups were categorized as NS and BC groups based on the types of pre-operative fluid and the amount of fluid administered during surgery. The primary outcomes were defined as electrolyte imbalance and acidosis immediately after surgery. The secondary outcomes were the length of stay in the intensive care unit (ICU) and duration from the end of the operation to extubation. Results : A total of 586 patients were enrolled in this study, with each of 293 patients assigned to the NS and BC groups, respectively. Immediately after surgery, serum chloride levels were significantly higher in the NS group. Compared to the NS group, the BC group had lower incidence rates of acidemia (6.5% vs. 11.6%, p=0.043) and metabolic acidosis (0.7% vs. 4.4%, p=0.007). As compared to NS group, BC group had significantly shorter duration from the end of the operation to extubation (250±824 vs. 122±372 minutes, p=0.016) and length of stay in ICU (1.37±1.11 vs. 1.12±0.61 days, p=0.001). Throughout multivariable analysis, use of BC was found to be significant factor for favorable post-operative results. Conclusion : This study showed that the patients who received BC during UIA clipping had lower incidence of metabolic acidosis, earlier extubation and shorter ICU stay compared to those who received NS. Therefore, using BC as a peri-operative fluid can be recommended for patients who undergo surgery for UIA.
