This study is the spatial characteristics of child education facilities through the cognitive development of child. Early childhood is the most important period in every human developmental stage; physical, emotional, and mental parts. Thus, the education in early childhood should be conducted naturally by a variety of experiences, sensibility, and physical activities, not by knowledge-oriented education which has been conducted until today. The education based on experience has been adapted, not only domestically, but internationally, and the early childhood education focused on child's development is especially emphasized in Europe. It's because the industrialization started earlier in Europe than in other countries, and it leaded to the entry of women in public affair. Consequently, early childhood education was taken charge of by the nation. While it has gone through trial and error, and Now it leaded to the better way. This study checks the common factors which shows the spatial characteristics based on experience and the relationship between the features of infants and concept of space in Piaget's theory. And then, I am going to systemize the relationship of each factor and suggest the design plan so that it could be applied methodologically when the space is designed for child education facilities beyond the current education only focused on programs.

Background: Video-assisted thoracoscopic surgery (VATS) is recognized as a safe and effective treatment modality for early-stage lung cancer and anterior mediastinal masses. Recently, novel articulating instruments have been developed and introduced to endoscopic surgery. Here, we share our early experiences with VATS major pulmonary resection and thymectomy performed using ArtiSential articulating instruments. Methods: At the Seoul Metropolitan Government-Seoul National University Boramae Medical Center, 500 patients underwent VATS pulmonary resection between July 2020 and April 2023, while 43 patients underwent VATS thymectomy between January 2020 and April 2023. After exclusion, 224 patients were enrolled for VATS major pulmonary resection, and 38 were enrolled for VATS thymectomy. ArtiSential forceps were utilized in 35 of the 224 patients undergoing pulmonary resection and in 12 of the 38 individuals undergoing thymectomy. Early clinical outcomes were retrospectively analyzed. Results: No significant differences were observed in sex, age, surgical approach, operation time, histological diagnosis, or additional procedures between the patients who underwent surgery using novel articulating instruments and the group treated with conventional endoscopic instruments for both VATS major pulmonary resection and thymectomy. However, the use of the novel articulating endoscopic forceps was associated with a significantly larger number of dissected lymph nodes (p=0.028) and lower estimated blood loss (p=0.009) in VATS major pulmonary resection. Conclusion: Major pulmonary resection and thymectomy via VATS using ArtiSential forceps were found to be safe and effective, with early clinical outcomes comparable to established methods. Further research into long-term clinical outcomes and cost-effectiveness is warranted.

Purpose: Competency is a key foundation of the nursing education curriculum and a baseline element of nursing practice. The purpose of this study was to explore the competencies of community health nurses in a maternal early childhood sustained home-visiting program based on nurses' field experiences. Methods: The participants were 21 nurses who had more than 1 year of experience in this program. Reflective interviews were performed; lasting 1 hour per nurse, on August 18, 2016, and the collected data were analyzed using qualitative directed content analysis. Results: Twenty-four themes were extracted for 9 competencies. The major themes included implementing a long-term relationship-based approach, providing client-led service rather than expert-led service, helping mothers with psychosocial difficulties, and applying skills in a practical manner in the home environment. Conclusion: In order to develop a home-visiting program as part of maternal-early childhood nursing practice, nurses should develop competencies that help them make significant and positive interventions. Results indicate that the curriculum for community health nurses should be changed to improve competencies in building relationships with clients and to focus on the application of skills in specific cases and in clinical practice.

This study was intended to investigate the influence of teacher empowerment on organizational? effectiveness, and the moderating effects of personal and organizational characteristics on the relationship of teacher empowerment and organizational effectiveness in early childhood educational institutes. The subjects in this study were 808 teachers who worked at kindergartens and childcare centers located in all parts of Korea. This study was surveyed with the questionnaires. The results are as follows. Firstly, teacher empowerment had a positive and meaningful influence on all components of organizational effectiveness, such as organizational commitment, job satisfaction, and job performance. Secondly, as for the moderating effects of personal and organizational characteristics on the relationship of teacher empowerment and organizational effectiveness, teachers' educational background had moderating effects on job performance of organizational effectiveness, and married or unmarried status of teachers, teachers' experiences in other institutes, type of institute, and the number of teachers working in an institute had moderating effects on organizational commitment. Also, the number of teachers working in an institute had moderating effects on job satisfaction. However, teachers' period of service in their present institutes didn't have moderating effects between teacher empowerment and organizational effectiveness.

In 2006, as a means to minimize early corrosion failure of ships, thus to enhance marine safety, International Maritime Organization (IMO), proposed a mandatory regulation for Performance Standards for the Protective Coatings (PSPC) for ballast tanks of newly built ships to satisfy 15 years of target useful life. In this regulation, several unprecedented strict rules are adopted as minimum, mandatory requirements for protective coatings of ship's water ballast tanks, and all type of ships sailing international sea are subjected to this regulation which is to be effective as early as June of 2008. The PSPC addresses many technical issues in the areas of surface pretreatment (primary and secondary), coating materials, coating application procedure and inspection as well as necessary documentation. The PSPC rules are new and unproven concepts, which calls for rigorous incorporation of reality-based evidences currently available, since there are no practical experiences in terms of the validity of the PSPC rules. There has been much controversy surrounding these regulations and considerable effort has been made by both shipyards and ship owners alike to achieve a performance standard for ballast tank coatings, which is acceptable to all. In this paper, the background and overview of the PSPC rules are given, and several issues in the PSPC are reviewed as a base to achieve robustness of the proposed PSPC, which will serve as a means to minimize early corrosion and to ensure 15 year target useful life of ships.

This study explored journal publishing and authorship by South Korean early career researchers (ECRs) in the field of library and information science (LIS). This research analyzed relevant journal publication data and conducted interviews to obtain information on the experiences and opinions of ECRs. Results indicated that South Korean ECRs in LIS were highly productive. This was evidenced by their annual publishing rate of 2.04 articles per person. In addition, Social Science Citation Index (SSCI) publications were produced at an annual average of 0.26 articles per person, while the quartile ratings for SSCI journal publications were also relatively high. However, unlike the trends seen in other academic fields, their collaborative research efforts were not considered very high because such efforts did not correspond to half their total publications. ECRs often participate as lead or corresponding authors despite being new researchers. ECRs are publishing first in the journals approved by their universities. These researchers cannot receive proper credit if the journal was not approved in this manner. ECRs are particularly disadvantaged when publishing in international journals corresponding to specific areas that are not on the SSCI list. By examining the journal publishing and authorship efforts of ECRs, this study discovered a variety of difficulties that should be addressed. For example, South Korean universities do not currently have cooperative research guidelines to solve authorship problems. The results from this study can serve as a basis to establish academic publishing and authorship policies while promoting scholarly communication in LIS and other scientific fields.

Grateloupia turuturu is a red alga with a flat but firm slippery thallus. Throughout its lifetime, this alga experiences a wide range of environmental stresses in the intertidal rocky shores. The aim of this study is to investigate the effect of salinity and irradiance on the early developmental stages of G. turuturu tetrasporophytes. The released carpospores were cultivated at different salinities (S = 15, 25, and 35) and irradiances (50, 100, and 200 μmol photons m^-2 s^-1). Germination of carpospores and development of juvenile tetrasporophytes were observed every 5 days and recorded by a digital camera. Discoid crusts were formed at all conditions within 5 days. The discoid crusts at 200 μmol photons m^-2 s^-1 died within 20 days regardless the salinity. The discoid crusts at S = 35 also died at all irradiance conditions within 25 days. Except for those at S = 35 and 200 μmol photons m^-2 s^-1, the discoid crusts reached about 8,000-9,000 ㎛² by day 20. Regardless of irradiance, the upright thalli formation rate from discoid crusts was 85 and 10% at S = 15 and S = 25, respectively. These results suggest that salinity and irradiance are important factors influencing early developmental stages of G. turuturu.

Background: Minimally invasive direct coronary artery bypass surgery(MIDCAB) has been increasing in interest along with the new techniques in myocardial immobilization for easier and safer procedures. Until the opening of the era of new techniques, adequate accuracy and good patency of grafts were debatable. Our experiences of MIDCAB were studied according to the stages of technical developments. Material and Methods: Since March 1996, 55 patients have undergone MIDCAB procedures. The patients of off-pump CABG(no cardiopulmonary bypass under full sternotomy) were excluded from the study. In the early experience(Stage I), a left anterior small thoracotomy through the left parasternal incision was performed(n=6); then an approach through the lower partial sternotomy was used(Stage II, n=33); and recently, a chest wall elevator for harvesting the internal thoracic artery and the foot plate for myocardial immobilization have been used(USSC, Norwalk, CT)(Stage III, n=16). Result: The surgical procedures of four patients in the Stage II group have been converted to conventional bypass because of the deeply seated left anterior descending coronary artery in two patients, fracture of the calcific lesion in the right coronary artery in one patient, and a cardiogenic shock during hypothermia in the other patient with ventricular dysfunction. Two patients in stage II experienced symptomatic recurrences after surgery and restenosis was verified on angiocardiography. They were managed by interventional procedures. All the other patients were doing well without symptoms, except one patients in Stage II who underwent PTCA procedure for a lesion in the circumflex artery during the follow up period. Conclusion: The new and specialized devices are essential to the development of MIDCAB surgery. MIDCAB and the hybrid procedures in multi-vessel disease are on the way to further development. So far, our experience is limited only to a single device among the many new devices for the purpose.

Purpose: To provide an in-depth analysis of the physical changes in and marital experiences of immigrant women in Korea, considering the differences in their cultural backgrounds. Methods: A qualitative research methodology with a phenomenology perspective was used. Data were collected through interviews from four focus groups and through in-depth interviews from five individuals. Data analysis was carried out using Colaizzi's phenomenological analysis method. Results: Twenty-four participants from nine different nations were interviewed. Three phenomenological theme clusters were identified and six sub-themes were derived. These comprise: "emergence of physical changes", "experienced symptom with negative result", and "coping with my body". The derived themes comprise: "struggling for my body to survive", "changed body after pregnancy and delivery", "diagnosed as normal but", "neglected my health", "using familiar care", and "unfamiliar health service system". Conclusion: Immigrant women by marriage in Korea are new subjects of nursing care. Their physical changes and experiences in coping with marriage at an early stage of immigration as described by themselves provide valuable information for nursing professionals. Cultural differences, problems specific to women, and our social conditions regarding minorities and our patriarchal tradition that discriminates against women affect their health problems. We strongly recommend that nurses should actively determine and engage in the health problems of immigrant women.
