In the case of high-voltage connectors applied to automobiles, waterproofing has become an important issue for the safety of automobiles. In this study, structural analysis is performed on silicone rubber- type waterproof seals used in the voltage connector. For the structural analysis, the tensile properties of the actual rubber seal are evaluated using a miniaturized tensile testing machine. The Mooney-Rivlin material constants of the rubber seal are determined as follows; D1=0, C01=0.241, C10=0.0142. The analysis shows that the contact pressure at the top of the seal where the seal and male connector are in contact is approximately three times higher than that at the bottom of the seal where the seal and female connector are in contact. It is confirmed that the waterproofing performance of the rubber seal depends on the contact pressure of the seal bottom where the seal and female connector are in contact. The contact pressure for waterproofing is found to be 4.7 bar. The strain concentration of the curved part is attributed to excessive initial tension. Therefore, a redesign is recommended for uniform stress or strain distribution in the curved section of the seal in response to the stress relaxation problem due to permanent deformation.

Purpose: The purpose of this study was to develop a military nursing curriculum for unification period of Korea for the 4th grade cadets of the Korea Armed Forces Nursing Academy. Methods: The study followed five steps. First, review the military manuals and governmental documents to clarity the mission of nursing officer during the unification period. Second, select framework to consist core categories of curriculum. Third, review the literature to identify the major health problems in North Korea, then consist the elements of each category. Forth, delphi survey was done by 10 expert panel to evaluate the validity of the categories and elements. Finally, a group of 8 experts have verified the validity of the curriculum overview, concepts and their composition. Results: The curriculum was consisted of 6 categories and 60 elements after delphi survey. Major categories include 1) medical support system of South Korea Government, 2) North Korea healthcare system, 3) management of communicable disease, 4) non-communicable disease, 5) reproductive health and sex 6) mental health. The content validity index of the contents selection and contents organizing was above 3.60. Finally, we designed 15-hour(1 semester) military nursing curriculum for 4th grade cadets. Conclusion: This study suggested the curriculum which is able to enhance capability of nursing cadets when unification period comes and they work as nursing officers.

This study examined the reproductive health-related experiences of North Korean women defectors and their sexual knowledge, sexual attitudes, and reproductive health promotion behavior. Convergent parallel mixed methods were used. From April to July 2020, 8 North Korean women defectors in Seoul metropolitan area were recruited by snowball sampling. In addition, 175 participants in the Seoul metropolitan area, Chungcheong, and Gyeongsang Province were recruited. Content analysis was conducted to analyze qualitative data, and the SPSS 23.0 program was used. Three themes were derived: scared of sex due to ignorance', 'the embarrassing and annoying sex only for duty', and had to manage myself for sex under the limited situation.'. The subject's sexual knowledge was higher in the older and married groups, and the sexual attitude was more liberal in the younger group. Reproductive health promotion behavior was more active in the high economic level, and sexual knowledge and sexual attitude showed a positive correlation. Therefore, it is necessary to provide support systems and resources from the community to encourage reproductive health promotion activities. In addition, in terms of humanitarian aid, prioritization of the reproductive health of North Korean women is required. 본 연구는 북한이탈여성의 재북당시 생식건강 관련 경험을 탐색하고 성지식, 성태도, 생식건강 증진행위 수준을 확인하기 위해 수행된 수렴병렬 혼합설계 연구이다. 2020년 4월에서 7월까지 수도권에 거주하는 8명의 북한이탈여성을 눈덩이 방식으로 표집 후 심층면담하여 질적자료를 수집하였고 수도권, 충청권, 경상권에 거주하는 175명의 북한이탈여성을 편의표집하여 성지식, 성태도, 생식건강 증진행위에 대한 설문조사를 실시하였다. 심층면담 결과는 내용분석을 실시하였고, 설문 결과는 SPSS 23.0 프로그램을 이용하여 independent t-test, ANOVA, Pearson’s Correlation Coefficients로 분석하였다. 질적자료 분석결과 북한이탈여성의 북한에서 경험한 생식건강 관련 경험은 ‘잘 알지 못하여 두려운 성’, ‘의무만 강요하는 부끄럽고 귀찮은 성’, ‘모든 것이 제한된 속에서 내가 스스로 알아서 관리해야하는 성’으로 나타났다. 양적자료 분석결과 대상자의 성지식은 연령이 높은 군과 기혼 군에서 높았고 성태도는 연령이 낮은 군에서 더 개방적인 것으로 나타났다. 생식건강 증진행위는 경제수준이 높은 군에서 더 활발하였고 성지식과 성태도는 양의 상관관계를 보였다. 국내에 정착한 대상자들이 재북기간에 가졌던 성에 대한 소극적인 태도를 극복하고 생식건강 증진행위를 수행할 수 있도록 지역사회의 지지체계 및 자원의 제공이 필요하며, 북한여성의 생식건강에 대하여 인도주의적 지원의 우선순위가 요구된다.

This paper describes a novel method for fabricating a metallic mold with narrow high-aspect-ratio intaglio micro pattern structures, hole and groove pattern width of 10 ㎛, and aspect ratio 4.0. Creating such structures by conventional micromachining with a 10-㎛-wide tool tip is difficult or even impossible. We first fabricated pattern structures with width of 10 ㎛ and height of 40 ㎛ by micro machining process with wider tool, and replicated metallic mold to form inverse structures by electroforming process. A passivation layer was used to prevent diffusion between the brass master and the electroformed metallic mold during electroforming. We demonstrated the feasibility of this process by measuring and analyzing the patterns imprinted using the metallic mold.

Purpose : The purpose of this study is to develop an integrated nursing curriculum on patient safety for the 4th grade cadets of Korea Armed Forces Nursing Academy. Method : For the Integrated nursing curriculum development, Dick & Carey`s ADDIE model was used. The analysis, design, and development phases were conducted in this study with the exception of implementation and evaluation. In the analysis stage, patient safety guidelines and the education needs of nursing officers in 10 military hospitals were analyzed. Based on the analysis, interviews, and literature review, the authors drafted education topics and contents in the design stage. During the development stage, the validity of the curriculum was checked by experts. Result : Education in four major categories of medication errors, falls prevention, communication, and nursing practice were in high demand. Each category was comprised of its own content items, and finally 39 items in total passed the validity test. The validity score of the 39 items ranged form 0.8 to 1.0. Based on these results, a 30-hour or 4-days program focusing on patient safety was developed integrating adult nursing, fundamental nursing, psychiatric nursing, and nursing management. Conclusion : This study is expected to contribute to improving clinical competency of newly commissioned nursing officers especially for patient safety. Further research needs to determine the effect of the integrated nursing curriculum.
