  • A new method is developed for estimating the mean of a population which has a linear trend. The suggested estimator is based on the balanced systematic sampling method and the concept of interpolation and extrapolation. The efficiency of the proposed method is compared with that of conventional methods.

  • The systematic study on the bryozoans from the South SEa in Korea was done with the materials collected at 49 localities from 1965 to 1991. As a result, 57 species in two suborders of cheilostomaous bryozoans were identified, which seven species, Electra tenella, Labioporella bursaria, Dendrobeania longispinosa, Sinupetraliella gigantea, Cryptosula pallasiana, Hippopodina feegeensis and Durystomella bilabiata were new to Korean fauna. The unrecorded species and the species which need remarking were described with plates.

  • A method is proposed for efficiently estimating the mean of a population which has a linear trend. The proposed estimator is based on the centered modified systematic sampling method and the concept or interpolation. Using the expected mean square error criterion, it is shown that the proposed method is more efficient than conventional methods in most real cases.

  • Purpose: This study aims to investigate effectiveness in foreign Health Promoting School through a systematic review. Methods: To perform a systematic literature survey, the researcher searched two database (PubMed and Springer Link) for literature relevant to 'health promoting schools' (published up to April 2013 from 2004). The key words used for the search were "effectiveness", "evaluation" and "health promoting school". five evaluations in this review were selected in the peer reviewed. Results: 1. The areas of standardized assessments were dealing with school health policy, physical environment, psycho social environment, community participation, Literacy on health, personal hygienic skills, academic achievement, self reported health status, and mental health. 2. There was evidence that the health promoting school has some positive influence on various domains of assessment. Conclusion: This systematic review provides evidence concerning the effectiveness of the health promoting school.

  • A systematic hoisting planning for tower crane is the most important elements in highrise building construction. However without sufficient data, systematic approach, it is not with ease to produce an appropriate planning at the rite. Therefore, this research aims at developing a systematic hoisting planning system in visual graphic with systematic procedure. The result of this research is that developed system on hoisting load calculation, numbers and specification of tower cranes are graphically visualized easily at the site. The study of applying this system to real project proves that it presents a sufficient capability as a useful tool in the hoisting planning of highrise building projects.

  • This paper aims to investigate the time-varying systematic risk of the stocks of Korean logistics firms. For this purpose, the period from January 1991 to October 2016 was examined with respect to 21 logistics companies that are listed on the Korea Exchange. The systematic risk of the logistics stocks is measured in terms of the Capital Asset Pricing Model (CAPM) beta for which the sensitivity of a stock is compared to the return changes of the whole market. Overall, the betas of the stocks of the Korean logistics companies are significantly lower than those of the market unity; however, it was revealed that the logistics betas are not constant, but are actually time-varying according to different economic regimes, which is consistent with the previous empirical findings. This finding is robust across different measurements of the logistics betas. In addition, the impact of macroeconomic factors on the logistics betas was examined. The present study shows that the logistics betas are positively associated with foreign exchange-rate changes.

  • 손실 채널의 데이터 손실을 보상하는 오류 정정 부호로 주로 사용되는 LT 부호는 일반적으로 RSD (robust soliton distribution)을 따르는 nonsystematic 구조를 가진다. RSD 를 따르는 유한한 길이의 LT 부호의 경우 높은 손실률 가진 채널 환경에서는 적합하지 않다. 본 논문은 기존의 RSD 를 다소 변형하여 systematic LT 부호에 적합한 무게 분포를 설계 방법을 제시하고, 시뮬레이션을 통해 기존의 RSD 를 이용한 LT 부호와 논문에서 제안하는 systematic 성질을 가진 LT 부호의 성능을 비교해 본다.

  • The purpose of this case study is to understand the sustainability practices of knowledge transfer process at the Malaysian government-industry-academia consortium. At this stage in the research, the R&D consortium is defined as an established entity by two or more organizations that pool resources and shared decision making for cooperative research and development activities. In attempts to understand the formation, outcomes and sustainability of the sustainable knowledge transfer process, this paper conducted a systematic literature review based on Gough, Oliver and Thomas systematic reviews protocol. From the review, the data were enriched and enhanced with a better understanding of sustainable knowledge transfer process. The systematic review resulted in identifying six factors including internal and external perspectives. However, key sustainability factors are not only directly influencing KTP, and the consortium, but are also mediated by other organisational variables.
