FCAW(Flux Cored Arc Welding), SAW(Submerged Arc Welding), EGW(Electro Gas Welding), and three-pole SAW are applicable in manufacturing the offshore wind tower. In this paper, mechanical properties of these welded-joints for TMCP steels were evaluated in all above welding processes. The tensile strength of welded-joints for all the welding methods satisfied the standard guideline (KS D 3515). No cracking on weldment was found after the bending test. Changes of weldedments hardness with welding processes were observed. In a weld HAZ (heat-affected zone), a softened HAZ-zone was formed with high heat input welding processes (SAW and EGW). However, the welded-joint fractures were found in the base metal for all cases and small decrease in welded-joint strength was caused by a softened zone. The multi-pole SAW welds exhibited similar mechanical properties comparing to the one with one-pole SAW process.

Purpose: Radiotherapy (RT) is considered a mainstay of treatment in parameningeal rhabdomyosarcoma (PM-RMS). We aim to determine the treatment outcomes and prognostic factors for PM-RMS patients who treated with RT. In addition, we tried to evaluate the adequate dose and timing of RT. Materials and Methods: Twenty-two patients with PM-RMS from 1995 to 2013 were evaluated. Seven patients had intracranial extension (ICE) and 17 patients had skull base bony erosion (SBBE). Five patients showed distant metastases at the time of diagnosis. All patients underwent chemotherapy and RT. The median radiation dose was 50.4 Gy (range, 40.0 to 56.0 Gy). Results: The median follow-up was 28.7 months. Twelve patients (54.5%) experienced failure after treatment; 4 local, 2 regional, and 6 distant failures. The 5-year local control (LC) and overall survival (OS) were 77.7% and 38.5%, respectively. The 5-year OS rate was 50.8% for patients without distant metastases and 0% for patients with metastases (p < 0.001). Radiation dose (<50 Gy vs. ${\geq}50Gy$) did not compromise the LC (p = 0.645). However, LC was affected by ICE (p = 0.031). Delayed administration (>22 weeks) of RT was related to a higher rate of local failure (40.0%). Conclusion: RT resulted in a higher rate of local control in PM-RMS. However, it was not extended to survival outcome. A more effective treatment for PM-RMS is warranted.

This study suggests policies to rearrange the status of Health Family Support Centers, targeting hands-on workers and centering on collected problems and improvements. To attain this aim, the study rearranged the materials investigated in 2009. On this basis, the study suggests the following policies. First, Health Family Support Centers changed into Korean Institute Healthy family which could prepare a means for opinion convergence through base organizations. Thus, it is necessary to establish a Gyeonggi-do wide area Health Family Support Center. Second, space and human resource arrangement, suitable to business, are necessary, and so are stable, secure finances. Third, urban areas, agricultural villages, and fishing villages are distributed across Gyeonggi-do. Thus, the development of specialized business, suitable to Gyeonggi-do, is necessary. Consequently, this study suggests executing obligatory family education (education for engaged couples, education for parents). Fourth, case management models, unique to Health Family Support Centers, have to be developed, as well as unified services related to education, counseling, and cultural businesses. Fifth, the Health Family Support Center has to secure its own status as a hub organization of inter-regional family businesses, has to strengthen its organizational identity, and has to promote suitable business development.

Purpose: This study aimed to analyze the effects of fatigue, resilience, and self-leadership on nursing service quality of local medical center nurses who nursed COVID-19 patients. Methods: The participants were 135 nurses who worked at regional public hospitals located in H-gun, G, and C-city in province C. The collected data were analyzed using descriptive statistics, t-test, analysis of variance (ANOVA), Pearson's correlation coefficients, and stepwise multiple regression using IBM SPSS Statistics version 25. Results: The participants' nursing service quality showed significant positive correlation with resilience (r=.53, p<.001), and self-leadership (r=.60, p<.001). The factors affecting participants' nursing service quality were commitment to self-leadership (β=.57, p<.001) and work position (chief nursing officer) (β=.26, p<.001), which explained 42% of the participants' nursing service quality. Conclusion: During a crisis such as the COVID-19 pandemic, it is necessary to help nurses enhance their self-leadership skills and build their career continuously by developing relevant policies, systems, and nursing intervention programs. Future studies could expand the knowledge base by including more participants to explore other ways to improve nursing service quality during the COVID-19 pandemic.

Acid-labile subunit(ALS)는 85-kDa 크기의 당단백질로서 7.5-kDa의 insulin-like growth factor(IGF) 및 40~45-kDa IGF-binding protein-3와 결합하여 150-kDa ternary complex를 형성하는 혈장단백질이다. 선행연구에서 본 연구진은 reverse transcription-polymerase chain reaction(RT-PCR) 방법으로 돼지(porcine) ALS(pALS)의 coding sequence를 합성하여 plasmid vector에 삽입시켜 ‘expression construct’를 제작한 바 있다. 그러나 본 expression construct의 pALS coding sequence에는 PCR error로 추정되는 원인으로 말미암아 2개의 bases에서 mis-sense mutation이 일어난 것이 발견되었다. 본 연구에서는 ‘site-directed mutagenesis’ 방법으로 pALS의 올바른 coding sequence를 합성하여 ‘insert DNA’의 마지막 codon 다음에 ‘His-tag’ sequence가 위치한 pET- 28a(+) plasmid expression vector에 삽입하였다. 본 expression construct는 E. coli BL21(DE3) 세포에서 ‘induction’ 시켰고, 발현된 유전자재조합(recombinant) peptide는 Ni-affinity chromato- graphy로 정제하였다. 이렇게 affinity chro- matography로 정제된 peptide는 SDS-PAGE에서 66kDa 위치에 single band를 나타냄으로써 recombinant pALS의 예상된 질량과 일치하였다. 이상의 결과는 본 연구에서 recombinant pALS peptide가 성공적으로 발현정제되었음을 시사한다.

The Cases of advanced nations which have advanced welfare policy, they have headed for the deinstitutionalization and the protection of the local society. So they have expanded and improved the various policies and welfare facilities to be able to keep daily life on the base of local area. Many problems have been caused by rising the average life span of the elderly in Korea now. Under the tendency, there have been many alternative proposals to solve the problems. One of those proposals, the deinstitutionalization theory that is rated the ideal way, is the community-based care than the care in facilities for the elderly. It shows that the most ideal facility for the care is Daycare center and that it matters the system of spatial construction and standard of the facilities. Under the undetailed Korean standard of facility design, it is very important that system of spatial construction to correspond to the needs of the users and standard of the facilities are prepared from the point of view of the standard design of the domestic facilities for the elderly. The study of the book grasps the regional present situation of the domestic Daycare center and surveys the tendency of the stay and features of occupation of the user there through some case, and aims to have a thorough grip of the spatial scale by the user's behavior. It is to utilize for a proposal for preparation of the space scale, and an institution standard corresponding to user's needs in a Daycare center.
