After Industrial Revolution, new thought system is needed to subdue multi-chanties and complexities of society. Nowadays under 'system theory', these efforts are theorized and organized in fields of science, philosophy and others. From Industrial revolution, before establishing the system theory, system has been needed by the expression methods. From that time, as it could be done, standardization, has been continued. Finally these conclusion reached at the systematic expression methods and when the system was build up, this theory was come true in Art such as De Stijl, Neo-Pasticism, Russian Suprematism and Constructism. For that reason, formal solution to achieve mass reductions was found in Art, so people connected Industry with Art at that time. Systematic expression methods in Art have characteristics of system and reflect mathematics and geometry theory which is based on the system theory. This study analyzes the systematic methods in contemporary interior space through the concept of systematic expression methods in Swiss Allianz's works which used the systematic expression methods and also inquires how the common meaning of system after recent times effect to contemporary design.

Acquiring accurate quantitative and qualitative information is necessary for the technical and scientific management of forest stands. In this study, stratification and systematic random sampling methods were used to estimation of quantitative characteristics in study area. The estimator ($((E%)^2xT)$) was used to compare the systematic random and stratified sampling methods. 100 percent inventory was carried out in an area of 400 hectares; characteristics as: tree density, crown cover (canopy), and basal area were measured. Tree density of stands was compared through systemic random and stratified sampling methods. Findings of the study reveal that stratified sampling method gives a better representation of estimates than systematic random sampling.

The systematic study of recent freshwater ostracods were conducted on the materials collected from 48 localities in South Korea. Four species of ostracods are identified, and all of them are new to South Korea : Cyprinotus uenoi Brehm , 1936, Heterocypris incongruens (Ramdohr, 1808), Dolerocypris fasciata(O.F.Mller, 1776 ), Dolerocypris sinensis Sars, 1903. Up to now seven species (5 species and 2 subspecies ) of recent ostracods are known to South Korea.

This study on the systematic study of ascidians from Korea was based on the materials collected at 41 localities from July 1969 to September 1989. 40 species, eight families, three suborders in two orders were identified, Of these four species were new records for Korean waters ; Polyclinum planum, Didemnum candidum, Stylea plicata, and Molgula calvata. They were described with illustrations, and the species which were characterized by spicules and siphonal armatures were added with plate figures.

The earlier literature widely documented the role of natural resources in economic development and confined their findings either in support of resource blessing growth or resource curse hypothesis. The ample research on the stated theme has available in the relevant databases, supported with empirical data, while a few studies used a case study or mixed-method approach. The study identified plenty of room on a given topic by conducting a systematic literature review and synthesizing the literature in more meaningful inferences. After a thorough investigation of the literature review through systematic intervention, the study concludes that natural resource management is imperative for a country's sustained growth. Simultaneously, it is desirable to reduce resource conflicts, improve institutional performance, decrease corruption, and stabilize the political environment to get maximum natural resource management potential globally.

As a result of the systematic study on the marine anascan bryozoans in Korea, a total of 27 species were identified and the following seven species were new to Korean fauna ; Membranipora perfragilis, Membranipora serrilamella, Terminoflustra sagamiensis, Callopora lineata, Thalamoperella rozieri, Canda retriformis and Amastigia xishaensis.

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.

Objective: To evaluate the completeness of the reporting of systematic reviews and meta-analyses published in a general radiology journal using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Materials and Methods: Twenty-four articles (systematic review and meta-analysis, n = 18; systematic review only, n = 6) published between August 2009 and September 2021 in the Korean Journal of Radiology were analyzed. Completeness of the reporting of main texts and abstracts were evaluated using the PRISMA 2020 statement. For each item in the statement, the proportion of studies that met the guidelines' recommendation was calculated and items that were satisfied by fewer than 80% of the studies were identified. The review process was conducted by two independent reviewers. Results: Of the 42 items (including sub-items) in the PRISMA 2020 statement for main text, 24 were satisfied by fewer than 80% of the included articles. The 24 items were grouped into eight domains: 1) assessment of the eligibility of potential articles, 2) assessment of the risk of bias, 3) synthesis of results, 4) additional analysis of study heterogeneity, 5) assessment of non-reporting bias, 6) assessment of the certainty of evidence, 7) provision of limitations of the study, and 8) additional information, such as protocol registration. Of the 12 items in the abstract checklists, eight were incorporated in fewer than 80% of the included publications. Conclusion: Several items included in the PRISMA 2020 checklist were overlooked in systematic review and meta-analysis articles published in the Korean Journal of Radiology. Based on these results, we suggest a double-check list for improving the quality of systematic reviews and meta-analyses. Authors and reviewers should familiarize themselves with the PRISMA 2020 statement and check whether the recommended items are fully satisfied prior to publication.

Purpose: The aim of this study was to analyze the cause of alcoholism based on a systematic review of previous studies published from 2009 to 2014. Methods: The study design was a systematic review of the literature in which factors constituting causes of alcoholism were analyzed. Search words used to retrieve foreign studies were "alcoholism" or a combination of "alcohol dependency" and "etiology" or "predictor. Research Information Sharing Service (RISS) of the Korea Education and Research Information Service and Dbpia, a database for domestic academic studies, were used as search engines for retrieving domestic papers. Results: The systematic literature review found that for emotional and psychological factors as etiology of alcoholism, abuse-related factors had the largest proportion with a total of 63%. Conclusions: In this study factors related to alcoholism were examined in terms of emotions, psychology, environments, families and others. As a result, it was found that alcohol consumption at an early age and experience of abuse were major causes for alcoholism.

In this paper, the data recovery performance of systematic erasure codes in burst loss environments is analyzed and the estimation method of redundant data according to loss characteristics is suggested. The burstness of packet loss is modeled by Gilbert model, and the performance of proposed packet loss recovery method in the case of using systematic erasure code is analyzed based on previous study on the loss recovery in the case of using erasure code. The required redundancy data fitting method for systematic erasure code in the condition of given loss property is suggested in the consideration of packet loss characteristics such as average packet loss rate and average loss length.
