Creative performance has been regarded as the key to the success of an organization in recent years, and is considered essential for the survival of an organization. Organizations must find and develop creative solutions to deal with a variety of business issues. How can organizations become more creative? To develop creativity, organizations must make it easier to connect the knowledge and perspectives of its various members, who may be scattered around the world, by developing a virtual team. Drawing from the transactive memory systems (TMS), which include expertise location, credibility, and coordination, this study investigates how the positive affect of team members influences the development of creative performance during virtual collaboration where face-to-face team activities are limited. The proposed structured model was empirically tested with cross-sectional data from 322 individuals. Results indicated that the positive affect of team members was found to moderate the relationship between TMS and creativity. Through this study, we expect to provide an understanding of the mechanisms involved in developing creativity among team members in a virtual work environment.

많은 학습시스템이 학습효율을 높이기 위해 자기 주도적 학습을 적용하고 있다. 동일한 수준의 학습자라 할지라도 학습 내용을 이해하는 정도는 서로 다를 수 있다. 따라서 제공된 콘텐츠를 이해하기 어려움에도 불구하고 정해진 난이도와 학습과정에 따라 획일적으로 학습이 진행되는 방법은 효율적인 학습효과를 나타내기 어렵다. 본 논문에서는 런타임시 변화된 학습자의 수준에 적합한 학습 콘텐츠를 재구성할 수 있도록 SCORM의 기능을 확장하고, 이 확장된 SCORM을 기반으로 DCOS(Differential Contents Organization System)을 설계 및 구현하였다. DCOS는 학습자의 수준에 적합한 학습 콘텐츠를 효율적으로 재구성하기 위하여, 학습자의 수준 이외에 학습 콘텐츠의 구성단위인 학습객체 간의 관련성 및 학습 목표 달성 정도를 기반으로 콘텐츠를 재구성하도록 하였다. 각 30명의 학생이 기존 시스템과 DCOS에서 학습한 결과, DCOS에서 학습한 학습자들의 평균점수와 시스템 만족도가 전체적으로 높은 것을 알 수 있었다.

러시아 정부는 세계 3위의 민간항공기 생산 강국을 목표로 민간항공기 제작기술 및 첨단 소재 확보를 위해 외국과 생산 제휴 등 전략적 협력을 확대하는 중이다. 또한 러시아 정부는 항공기 제작산업의 발전을 지원하고 항공 인증 조직을 개편하여 체계적인 항공안전 확보를 추구하고 항공제품 수출을 위한 국제협력과 인증활동에 많은 노력을 기울이고 있다. 국가 간에 민간항공기 안전 및 인증분야의 협력체계를 구축하기 위해서는 전반적인 인증시스템에 대한 상호간의 이해와 신뢰를 구축하는 과정이 요구된다. 따라서 본 연구에서 러시아의 항공기 인증조직, 법령체계, 인증절차를 분석하여 러시아의 항공기 인증체계에 대한 이해를 돕고자 하였다.

Culture is that the system of shared beliefs, values, customs, behaviors, and artifacts that the members of society use to cope with their world and with one another, and that are transmitted from generation to generation through learning. Members of an organization are affected by culture. And dissensions in an organization give negative effects to behavior of the members, especially to satisfaction from organization. This study is on the dissension management by considering of cultural characteristics of pilots. Cultural characteristics of pilots were surveyed and analyzed with the V5M94(values survey module94) which was developed by Hofstede. As results, the cultural indexes of the pilots were different from the national means. The indexes presented that korean pilots' cultural characteristics are low POI, high IDV, low MAS and low UAI as North European cultural characteristics. For managing the pilots group, make expansion of opportunity to take part in decision making, release or share of informations are required. And motivations, delegation, free from unnecessary interventions, understanding and forgiveness rather than disciplinary punishment, thoughtful considerations could be effectiveness. And for developing more effective management methods, management strategies of north european airlines should be studied.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through focus group's investigations on the elementary mathematics teacher's guide books. First, We survey previous studies on the teacher's guide books to make the frame of investigation. Next, We compose focus group(8 teachers) for 3~4th grades, and analyze the teacher's guide books according to ready-made frame: compliance of curriculum, accuracy and fairness of contents, selection and organization of contents. As results of investigation, system of organization of the teacher's guide books is needed. Goal, contents, teaching methods, and evaluations have to be consistent in describing mathematical terms. And errors in mathematics and mathematics education are examined more carefully. The teacher's guide books afford teachers many materials and informations to teach mathematics through classroom lessons. So more study on the teacher's guide books and developmental study for the model guidebooks is needed along with the revised curriculum and new textbooks.

Objectives: Young mothers are vulnerable to postpartum depression due to role transition-related stress. Understanding the causes underlying these stressors is essential for developing effective interventions. Methods: This study analyzed the 2018 Indonesian Basic Health Research data. The Mini International Neuropsychiatric Interview was used to assess postpartum depression symptoms in mothers aged 15-24 years with infants aged 0-6 months. In 1285 subjects, the risk factors for postpartum depression were evaluated using multivariate logistic regression. Results: The overall prevalence of depression in the 6 months postpartum was 4.0%, with a higher prevalence in urban areas (5.7%) than in rural areas (2.9%). Urban and rural young mothers showed distinct postpartum depression risk factors. In urban areas, living without a husband (odds ratio [OR], 3.82; 95% confidence interval [CI], 1.24 to 11.76), experiencing preterm birth (OR, 4.67; 95% CI, 1.50 to 14.50), having pregnancy complications (OR, 3.03; 95% CI, 1.20 to 7.66), and having postpartum complications (OR, 5.23; 95% CI, 1.98 to 13.80) were associated with a higher risk of postpartum depression. In rural areas, postpartum depression was significantly associated with a smaller household size (OR, 3.22; 95% CI, 1.00 to 10.38), unwanted pregnancy (OR, 4.40; 95% CI, 1.15 to 16.86), and pregnancy complications (OR, 3.41; 95% CI, 1.31 to 8.88). Conclusions: In both urban and rural contexts, postpartum depression relates to the availability of others to accompany young mothers throughout the postpartum period and offer support with reproductive issues. Support from the family and the healthcare system is essential to young mothers' mental health. The healthcare system needs to involve families to support young mothers' mental health from pregnancy until the postpartum period.

Organizations worldwide make efforts to develop their management systems for business functions. The representatives of management systems include quality management system (QMS), environmental management system (EMS) and occupational health and safety management system (OHSMS). Implementing EMS and/or OHSMS in addition to QMS often requires integration of separate management systems in alignment with the organization's strategies and goals. Through the questionnaire survey on Korean marine equipment enterprises, this paper deals with the operational practices of management systems and analyzes perceptions about integrated management system (IMS). We found out the degree of perception is not sufficient enough to prepare background for IMS in Korean marine equipment enterprises. The results contribute to well understanding and successfully implementing IMS.

The materials applied to the aircraft fuselage, parts, and components must be verified by relative authorities in accordance with the procedures set by the airworthiness authority to achieve the aircraft type certification. There are no examples of domestic composite materials which were verified in order to be applied to aircraft structure. In this study, the composite material certification system of NCAMP, an American composite material standard certification organization, was reviewed and used as the fundamentals of the first aerospace composite material certification system in ROK(Fig 2,8). Also updated material certification documents were developed and confirmed by material certification engineers and inspectors. This aerospace composite material qualification system is intended to modernize the material certification system for AAM(Advanced Air Mobility) as well as aircraft and to enhance the understanding of related technicians and inspectors.
