  • The objective of this research is to select the most effective technique from task related techniques(motion & time study, job redesign, physical environment improvement) for improving work efficiency in shipbuilding enterprise. This study consists of several principal steps. The first step is to design critical criteria in evaluating work efficiency in shipbuilding enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP(Analytic Hierarchy Process)structure using the critical criteria, sub-criteria and techniques from task related techniques. The fourth step is to develop the pairwise comparison matrix by each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique from task related techniques using AHP analysis. The result of AHP analysis has shown clear difference in priority among task related techniques in terms of work efficiency of the shipbuilding enterprise: The reduction of normal time has more importance than the reduction of allowance time, motion & time study techniques are most important for the reduction of normal time, physical environment improvement is most important for the reduction of allowance time as well.

  • 수소를 기반으로 하는 신재생에너지의 생산, 관리 및 이용 시스템을 연계하여 운전하는 Green City 실증단지 구현을 위한 국내 도서 선정은 지자체별 이해관계와 지역발전계획에 따라 첨예한 논란을 수반할 소지가 있다. 입지 선정 절차상에서 예비후보지 선정과정이 형식적이거나 입지선정기준이 없어 입지선정을 위한 평가항목, 평가기준, 항목별 배점 등이 분석자의 의도에 따라 조정될 수 있는 문제점이 있다. 또한 각 지역에 대한 입지선정을 위한 기준이 있다 하더라도 추상적이거나 객관적이지 않은 기준이 많아 입지선정에 직접 적용하기 어렵고, 자연환경, 사회경제, 법제, 입지조건, 부하특성, 지자체 호응 등 인자들의 평가의 형평성이 결여될 수 있다. 이를 해결하기 위해 의사결정도구로 이용되는 계층분석법(AHP)을 입지선정절차에 적용하였다. 객관적인 정보가 제공 가능한 평가항목을 설정하고, 관련 전문가들의 설문조사를 통하여 주관적인 중요도 결과를 취합하였다. 이 결과를 계층분석법을 활용하여 평가항목별 가치를 측정하여 가중치를 부여하였고, Green City 실증단지 구현을 위한 후보도서의 순위를 제시하였다.

  • Zygnema is a conjugating filamentous green algal genus that is distributed in a broad range of freshwater habitats, from sea level to alpine summits. Although more than 150 species have been described worldwide, their taxonomy remains unclear, probably owing to their relatively simple morphology. We investigated the detailed morphology of Korean Zygnema species, combined with analysis of the plastid psbA gene from 22 specimens of the genus and putative relatives, in order to develope a key to their identification and isolation, and to determine their relationships. We recognized two species of Zygnema; Z. insigne and Z. leiospermum, based on morphological characters such as width of the vegetative cell, position of zygospores, dimensions and form of spores, shape of female gametangia, and color of mesospores. The analysis of psbA data was consistent with morphological comparison. The pairwise divergence between two species was 3.7-4.1% (34-38 bp) in psbA sequences. The phylogeny of psbA revealed the monophyly of Z. insigne and Z. leiospermum together with two isolates of Z. circumcarinatum from Germany and Scotland. This is the first report on the psbA gene phylogeny of Zygnema.

  • The traditional AHP(Analytic Hierarchy Process) is to evaluate subjectively the alternatives in the view point of each of criteria and has been widely used at the fields of real world application. The AHP has some drawbacks that makes it difficult to keep the consistency of decision makers' input and take too long to get accurate results because of requiring lots of pairwise comparison between criteria and alternatives. This research is to propose and develop a Hybrid-AHP system for complementing the critical points of traditional AHP methodologies. This system gets the quantitative information as well as qualitative inputs as the comparative ones between criteria and alternatives. We use the input as various type of information such as quantitative values, 9-scale ratings, and fuzzy-based inputs. Finally, we applied the system to the case of choosing strategic industries. The case study have shown the use of various input methods saves processing time, and reduces the input burden of users.

  • Purpose - Labor productivity is extremely important to the profitability and competitive advantage of organizations that provide services to customers, such as banks. This study investigates the factors driving labor productivity in Iran's Melli Bank. Research design, data, methodology - Five managerial, psychosocial, cultural, and individual factors are identified and their relative importance for labor productivity prioritized using AHP. The required data are then collected through a questionnaire designed for a pairwise comparison of the driving factors of labor productivity and their subcategories. Results - The study outcomes reveal that the managerial and individual factors are the most important. Specifically, the most important factors in increasing labor productivity in the branches of Melli Bank are having a competent supervisor, promotion opportunities, fair working conditions, conscientiousness, the right tools, and a correspondence between skills and work. Conclusions - Implementing AHP using Expert Choice software revealed that, among the driving factors of labor productivity (i.e., managerial, psychosocial, cultural, environmental, and personal), managerial factors were considered the most important by the respondents.

  • The present study was designed to answer the following questions: 1) Is there and relationship between the adolescent's sex role identity and perceived parent behavious? 2) Is there any gender differences in perceived parent behavious? 3) Is there any interaction effect between sex role identity and gender in perceived parent behaviors? 109 male and 101 female undergraduates from the five universities in Seoul served as subjects in this investigation. Subjects were administered the Parent Behavior From (PBF) and the Bem Sex Role Inventory (BSRI) in counterbalanced order. A4 (sex-role identity)×2(gender) multivariate analysis of variance was performed for the perceived paternal and maternal behaviors separately. The simultaneous confidence intervals for pairwise comparison were followed when the MANOVA was significant. In testing all hypotheses, .05 was used as a significance level in this study. For the perceived paternal behavious, 1) The androgynous group, compared with the undifferentiated group, reported greater father warmth, active involvement, greater encouragement of cognitive independence, cognitive curiosity, cognitive competence, achievement control, and conformity. 2) The androgynous individuals showed higher father warmth, congitive independence, curiosity, and cognitive competence than the feminine individuals. 3) The androgynous individuals were found to have significantly higher father warmth than the masculine individuals. For the perceived maternal behaviors, there was a significant difference between gender groups in conformity. Daughters reported higher conformity than sons. The interaction effect between sex-role identity and gender, however, was not found to be significant.

  • The aim of this study was to identify strain KCOM 1265 isolated from subgingival plaque at the species level by comparing 16S ribosomal RNA gene (16S rDNA) and genome sequences. The whole genome of strain KCOM 1265 was extracted using the phenol-chloroform extraction method. 16S rDNA was amplified using polymerase chain reaction and sequenced using the dideoxy chain termination method. Pairwise genome comparison was performed using average nucleotide identity (ANI) and genome-to-genome distance (GGD) analyses. The data showed that the percent similarity of 16S rDNA sequence of strain KCOM 1265 was 99.6% as compared with those of Fusobacterium polymorphum ATCC 10953T and Fusobacterium hwasookii KCOM 1249T. The ANI values of strain KCOM 1265 with F. polymorphum ATCC 10953T and F. hwasookii KCOM 1249T were 95.8% and 93.0%, respectively. The GGD values of strain KCOM 1265 with F. polymorphum ATCC 10953T and F. hwasookii KCOM 1249T were 63.9% and 49.6%, respectively. These results indicate that strain KCOM 1265 belongs to F. polymorphum.

  • With a view to analyzing the influential factors and their prioritization in association with the loss from construction disasters, this study has presented relative weighted value and importance for each category of loss by making a systematic classification of costs for non-insured categories (indirect costs) and conducting AHP analysis based on results of a survey of specialists. Through the study, first, I have divided the larger classification of loss factors into human loss factor, financial loss factor, special cost factor, and managerial loss factor, and, second, have presented prioritization of loss categories by allotting scores based on weighted values after calculating weighted value through pairwise comparison of loss levels. Based on these results of the study, we should be able to qualitatively calculate the loss costs that construction disasters inflict on business, promote rational decision-making and efficiency in spending related to a disaster, and compare it against safety investment designed to reduce disaster loss from the perspective of business strategy.
