  • Breast cancer ranks among the most prevalent forms of malignancy and foremost cause of death by cancer worldwide. It is not preventable. Early and precise detection is the only remedy for lowering the rate of mortality and improving the probability of survival for victims. In contrast to present procedures, thermography aids in the early diagnosis of cancer and thereby saves lives. But the accuracy experiences detrimental impact by low sensitivity for small and deep tumours and the subjectivity by physicians in interpreting the images. Employing deep learning approaches for cancer detection can enhance the efficacy. This study explored the utilization of thermography in early identification of breast cancer with the use of a publicly released dataset known as the DMR-IR dataset. For this purpose, we employed a novel approach that entails the utilization of a pre-trained MobileNetV2 model and fine tuning it through transfer learning techniques. We created three models using MobileNetV2: one was a baseline transfer learning model with weights trained from ImageNet dataset, the second was a fine-tuned model with an adaptive learning rate, and the third utilized early stopping with callbacks during fine-tuning. The results showed that the proposed methods achieved average accuracy rates of 85.15%, 95.19%, and 98.69%, respectively, with various performance indicators such as precision, sensitivity and specificity also being investigated.

  • Purpose: The purpose of this study was to examine the moderating mediation effect of self-esteem on the relations among adolescents' abuse experiences, depression and anxiety, and suicidal ideation. Methods: The participants were selected using secondary data from a population in the 2012 Korea Welfare Panel Survey (KOWEPS). Data were analyzed using SPSS 15.0 and SPSS Macro, and bootstrapping and hierarchical regression analysis were performed to analyze multilevel models. Results: First, analysis of the mediating effect of the adolescents' abuse showed that there was significant mediating influence between suicidal ideation and depression and anxiety. Second, hierarchical regression analysis showed that self-esteem had significant mediation effect on depression and anxiety in adolescents' suicidal ideation. Third, SPSS Macro showed that self-esteem also significantly moderated the mediating effect of adolescents' abuse experiences on suicidal ideation through depression and anxiety. Conclusion: The study results suggest that in future research on adolescent's abuse experience, the risk of suicide in depression and anxiety scores should be selected through evaluation of each individual's self-esteem scale. Coping strategies with immediate early intervention should be suggested.

  • Laparoscopic surgery has become popular in the past few decades, owing to less postoperative pain, fast recovery, and better cosmetic outcomes. The laparoscopic approach has been employed in pediatric surgery for the same reasons. After the first attempts of single incision laparoscopic appendectomy in pediatrics in 1998, single incision laparoscopic surgery (SILS) has recently been proven to be safe and feasible for the pediatric population. However, limitations have been reported for SILS, such as the wide learning curve, compared to standard laparoscopic surgery, and the restricted number of hospitals with surgical training programs including SILS. In this study, we intend to present our initial experiences with SILS in children, and to describe the technique, instruments used, and outcomes. This is a retrospective study of 71 pediatric patients who underwent SILS, at a tertiary medical center, between September, 2012 and August, 2013. Electronic medical records were reviewed for demographics, type of procedure, operation time, use of additional ports, conversion to open surgery, complications and hospital stay. Additional ports were inserted in 4 cases, for the purpose of traction. Postoperative complications were noted in 13 cases, which were mostly related to wound inflammation or formation of granulation tissue. According to our analyses, patients with complications had significantly longer use and more frequent use of pain killers. Notwithstanding the small sample size, many of the procedures performed in pediatric patients seem to be possible with SILS.

  • Objective: The purpose of this study was to investigate the influence of experiences in close relationships with teachers for young children on their depression and to see whether there would be a mediating effect of their self-compassion. Methods: The subjects were 206 teachers recruited from Seoul and five different provinces who currently worked at the kindergarten and child care centers and agreed to participate in the survey. The data were analyzed by means of frequency, percentages, Cronbach's reliability coefficient and Pearson's correlation using SPSS 25.0 and model 4 provided in The PROCESS macro for SPSS 3.4 version. Results: The findings were as followed. First, the teachers' degrees of anxiety and avoidance for their close relationships were below the median scores. In contrast their degree of self-compassion was above the median score. In addition, their level of depression was relatively low. Second, both of the teachers' anxiety and avoidance for their close relationships had a positive impact on their depression and their self-compassion, and there were the partial mediating effect in both cases. Conclusion/Implications: These results imply that the early attachment experience connecting the experience in close relationships in the adulthood is important and that it is necessary to develop a program to enhance teachers' self-compassion to protect their psychological well-being.

  • The purpose of this study is to understand a migrant women's married life. The study examined migrant Filipino women's married lives, motives for marriage and migration to Korea, and their married life experiences. The results showed that these women get married to Korean men in pursuit of an economically better life to support their family in the Philippines through marriage migration. As for Filipino women's perceived difficulties in married life, they indicated hardships with redrawing the boundaries of nationality, as well as their husbands' faults or bad habits which are different from what they expected before marriage. Other difficulties mentioned were the peculiar culture of living with parents-in-law, and general difficulties in married life. This study showed that marriage migration results not from external pressure or motives but ultimately from their own decision in a social and cultural context. It was also implicated that Korea's superior position to the Philippines in international economic power has an effect on family relations. The boundaries of nationality are redrawn according to their married life. In addition, it was revealed that the Korean born children of migrant mothers who divorce because of difficulties in married life are in a very poor situation as their national identity depends on their mother's future marriage relations.

  • The main purposes of this study are to appraise the family-centered case-management (FCCM) practices in terms of building the community networking efforts, and to propose the practical improvement suggestions to overcome the barriers in practicing the current Healthy Families Policy, FCCM. The blended methodology was employed by collecting the quantitative and qualitative data sets including an staff's on-line survey, in-depth interviews(site case studies), and FGIs. As results, the authors found, despite the building and maintaining functional community networks was the essential and critical condition for the FCCM policy deliveries, many staffs have faced hardships in FCCM practices such as building a new network or finding an available and apt network within their communities. The lack of previous experiences in case-management exaggerated the functional difficulties thus, the new staffs were more prone than the staffs with 2 or more years experiences to the misunderstanding about the missions and tasks related to FCCM. Authors suggested that various on-the-job-training should be provided to eliminate those obstacles to build and/or maintain the community network for FCCM. Also, it is necessary for the each institution's director or managers to understand the FCCM and its relation to community networking, and to support FCCM staff members.

  • Objective: The purpose of the present study was to find out the development of 4-year-old children's emerging poetry composition process and features of poetic expression through their own forest experiences. This research also aims to explore the possibility of alternative poetry education for early childhood. Methods: This study collected data from one class of four-year olds through classroom observation, interviews with teachers, and the researcher's journal entries on events that occurred during forest walking activities. Results: Research findings showed that it was possible to encourage free expression of metaphors and imagination in children and they were able to share excitement about poetry with their classmates when provided with an alternative environment. One remarkable finding was that children's spontaneous writing and pleasure in poetry did not continue when given the new theme of 'Mom and Dad'. Conclusion/Implications: The results imply that to encourage the development of children's intuitive poetic words we need to be interested in how to organize and highlight the experiences of children. This study also suggests that positive methodological and teleological changes are needed for poetry education that is separate from language education.

  • The Fontan principle of redirecting systemic venous blood into the pulmonary arteries via a conduit was initially proposed for Tricuspid Atresia, but it and its modifications have now gained a much wider application than initially intended. From September 1978 to July 1983, Atriopulmonary anastomosis has been performed in 23 patients, 2 months to 19 years of age, Seoul National University Hospital. The diagnoses were Tricuspid Atresia [TA] in 13, Univentricular Heart [UVH] in 9 and one case of Double Outlet of Right Ventricle [DORV]. Previous procedures included two Glenn shunts and one Blalock-Taussl8 shunt. Among these 23 patients, 10 patients had Right Atrial to Pulmonary Artery conduit, with a valve in 7 and without in 3. The remaining 13 patients had direct anastomosis between RA to PA. There were 14 early deaths, 7 of 13 TA patients, 6 of 9 UVH patients and one DORV, and the total hospital mortality was 60%. But there were no later deaths, 9 of these 23 patients survived operation and are presently alive. The Fontan procedure can be done with an acceptable low mortality with good functional results for Tricuspid Atresia and other complex lesion in foreign hospital, but till now our results revealed much higher risks. For our good operative results and effective patients selection, we must clarify the exact condition of pulmonary arterial system and accumulate much more experiences and technique.
