Space development program is a large and complex system consisting of a multi-disciplinary high-end technologies and it is important to implement a program management system connected with systems engineering as well as to develop critical technologies. Major organizations in space fields carry out effective budget execution management and operation according to the strategy and objective of space development using information systems. Korea Space Launch Vehicle II(KSLV-II) has adopted a cost management plan using a system engineering to complete the program within the assigned schedule and budget. This paper introduces the budget execution management system applied to KSLV-II budget management and the budget execution dashboard system for supporting program decision making.

The dyeing properties of 100% PLA fabric and PLA/PET union fabric were examined with 4 different types of disperse dyes in this study. Disperse dyes were highly absorbed by PLA fiber in the temperature range of $100{\sim}110^{\circ}C$, K/S values of dyed PLA fabric with azo disperse dyes were much higher than those with anthraquinone dyes. It was found in the simultaneous dyeing of PLA and PET fabrics in the same bath that disperse dyes were mainly exhausted on PLA fiber at early stage of dyeing and migrated to PET fiber at the elevated dyeing temperature. Consequently K/S values of PET became higher as the dyeing temperature increased. Color differences appeared between PLA part and PET part in the union fabric dyed with 4 disperse dyes.

Objectives : This study investigated poor self-rated health and its associated factors in married Korean women, focusing on the burdens related to family affairs and social support. Methods : Cross-sectional data from 3,039 married women (between 25 and 64 years old) who completed Korean Longitudinal surveys of Women and Families were analyzed. Results : Among working women, only two factors-lack of husband's involvement in housework and insufficient communication with husband - influenced poor self-rated health. Among housewives, lack of husband's involvement in housework, insufficient communication with husband, low satisfaction of marriage, and avoidance of alcohol consumption were associated with poor self-rated health. Conclusions : Regardless of whether women are employed or housewives, husband's support is a very important factor affecting women's health. Social efforts for changing perceptions and values are needed so that men and women mutually support each other in family affairs.

본 연구는 국내 대학의 중국어-한국어 탄뎀수업에서 학습자주도 평가 방법으로 동료평가를 도입하여 이에 대한 학업성취도와 학습자의 정의적 태도에 미치는 영향을 분석하고, 동료평가와 교사평가와의 일치도를 알아보고자 한다. 연구 대상은 부산 지역 대학의 2학년 중국어-한국어 탄뎀수업 수강자 224명으로 학생들은 동료평가와 교사평가를 실시한 실험반과 교사평가를 실시한 통제반으로 나누어 한 학기 동안의 탄뎀 학습과 3차례의 평가 활동을 하였다. 그 결과 첫째, 실험반, 통제반 모두 학업성취도에서 긍정적인 효과가 보였다. 둘째, 학습태도 변화에서는 실험반에서 유의미한 효과가 있는 것으로 나타났으며, 마지막으로 동료평가와 교사평가 사이의 일치도는 비교적 높게 나타났다. 이는 동료평가방법이 신뢰할 수 있는 평가방법이자 탄뎀수업에서 충분히 활용가능성 있음을 보여주고 있으며, 학습 효과도 긍정적임을 증명한다. This study tried to find out the feasibility of using student evaluation in the Tandem learning class。The objectives of this study are to measure the agreement level between students evaluation (peer-evaluation) and teacher-evaluation, and to investigate the effectiveness of students’ participation in evaluation for academic performance. The subjects for this study are 224 university second year students from Busan province in South Korea. They are divided into 2 groups; student evaluation(peer-evaluation) group and conducted the teacher-evaluation on Tandem learning and evaluation activity practice. The results are first experimental group(peer-evaluation)& control group (teacher-evaluation) effected academic achievement positively. Second, experimental group showed high synchronization with experimental group, and the agreement between assessment of peer-evaluation group and teacher-evaluation group indicated high level. The results from this study mean that peer evaluation can be used as an alternative method to teacher evaluation and proves that even a positive learning experience.

우주 선진국의 우주개발 경쟁이 가속화되고 민간의 우주산업 참여와 투자가 확대됨에 따라, 복잡하고 어려운 우주임무로 인한 위험이 점차 증대함으로써 전세계 우주보험 시장 규모도 꾸준히 증가하고 있다. 각국의 우주활동 참여자들은 국제·국내 법체계에서 명시하는 의무 보험과 위험 발생에 따른 재산상의 손해를 자체 담보하기 위하여 보험에 가입하고 있다. 본 연구는 우주물체 발사 주체인 발사 서비스 제공자로서 발사 관련 다양한 위험 요인을 담보하는 보험 가입을 위하여 우주보험시장의 동향을 살펴보고 누리호 개발 및 발사 관련 보험 가입 사례를 기술하였다. As the space development race among advanced nations accelerates and private sector participation and investment in the space industry expand, the risks associated with complex and challenging space missions are gradually increasing. Consequently, the global space insurance market has been steadily growing. Participants in space activities from various countries are subscribing to insurance policies to cover their obligations under international and domestic legal systems and to protect against property losses resulting from risk occurrences. This study examines the trends in the space insurance market to facilitate the insurance coverage of various risk factors related to the launch as the launch service provider and describes case studies of insurance coverage related to the development and launch of the Nuri.

Recurrence of hepatocellular carcinoma (HCC) after hepatic resection is quite common. Peritoneal recurrence has been considered incurable status and related to poor prognosis. Although peritoneal metastasectomy is a therapeutic option for some selected patients with a few peritoneal metastasis, the indication and therapeutic effect has not been clear. We report a case of a 61-year-old man achieving complete remission of recurrent peritoneal metastasis after repeated surgical resection by a multidisciplinary approach. Peritoneal metastasectomy might be a therapeutic option for selected patients with localized oligonodular peritoneal metastasis. (J Liver Cancer 2017;17:153-157)

본 연구는 국내 대학교의 교양중국어 교육과정 개선에 대한 필요성에서 출발하여 교양중 국어 교육 체계 강화를 위한 교육과정 재구성 시도의 일환으로 현재 전국 대학의 교양중국어 교육과정 현황과 두 개 대학 학습자들의 인식 및 요구를 조사하고 분석하였다. 본 연구는 학습자의 충분한 이해와 요구에 따라 학습자 중심의 교육 과정 및 지침을 개발하여 효율적인 교양중국어 교육과정 개발을 위한 기초 작업을 목표로 하고 있다. 이에 국내 46개 대학에서 수집한 교양중국어 교육과정을 비교, 조사, 분석하였다. 분석한 내용은 교양중국어 필수 지정 여부, 시수, 학점, 수준별 분반, 교과목, 교재 등을 포함하고 있다. 또한 설문 조사와 인터뷰를 통해 학습자들이 가지고 있는 교양중국어 과정에 대한 인식과 관련 요구도를 조사하고 분석하였다. This study aims to enhance the quality of general Chinese in university by developing learner-centered curriculum and instruction based on student s needs. In an effort to develop an effective general Chinese program of a university, the present study examined curricular and learner needs for general Chinese courses of universities. The curricular of general Chinese programs collected from a total of 46 universities in South Korea were analyzed to examine class teaching hours, credits, courses, diffentiated-level classes, special courses, and a waiving policy of credits based on student proficiency. Also the survey and the interviews were carried out with the students studying in one university (N=387) to find out their needs on general Chinese courses. The curricular analysis showed the followings: 1) When analyzing the general Chinese courses curriculum of 46 universities surveyed, most of universities preferred 2~3 hours/2~3 credits Chinese courses,; 2) The results of surveys showed that the participants have strong needs for improving differentiated-level education. 3) It seems to be necessary to accommodate learners, teachers demand and realistic constraints on learning Chinese language learners.
