  • Objectives : The purpose of this study is to determine the safety and efficacy of low level laser. Methods : We searched 11 electronic databases(Pubmed, CAJ, EMBASE, Medline, Cochrane Library, KMBASE, KISS, KISTI, NDSL, RISS, Oasis) up to March 2019. We included randomized controlled trials(RCTs) using low level laser for alopecia. The methodological quality of each RCT was assessed by the Cochrane risk of bias tool. Results : 8 RCT studies were eligible in our review. The meta-analysis of 2 studies showed favorable results for the use of low level laser with minoxidil 5% than minoxidil 5% and 6 studies showed favorable results for the use of low level laser than placebo light. The results of meta-analysis showed that low-level laser has an efficacy on alopecia. There were no serious side effects or adverse effects. High risk of bias were observed in all studies. Conclusion : Now limited evidence is available to support low level laser for alopecia and further well-designed RCTs should be encouraged.

  • Risk analysis process, which identifies vulnerabilities and threat causes of network assets and evaluates expected loss when some of network assets are damaged, is essential for diagnosing ISP network security levels and response planning. However, most existing risk analysis systems provide only methodological analysis procedures, and they can not reflect continually changing vulnerabilities and threats information of individual network system on real time. For this reason, this paper suggests new system design methodology which shows a scheme to collects and analyzes data from network intrusion detection system and vulnerability analysis system and estimate quantitative risk levels. Additionally, experimental performance of proposed system is shown.

  • This study was conducted to examine trends in research about nurse educators in Korean hospitals. The methodological framework consisted of previous work by Arksey and O'Malley. A literature search was performed of electronic databases (RISS, KISS, CINAHL, and PubMed) from January 2000 to June 2022. Each study was collated and analyzed, and the studies' data were abstracted into the following categories: publication year, study design, study participants, and education program details. Eight studies were reviewed. Most of the studies were published after 2020 (87.5%). The most frequently used design was quasi-experimental (50.0%). There were three studies whose subjects were nursing educators and five studies were conducted on programs in which nurse educators participated. In Korean medical institutions, clinical nurse educators have various roles, including the development and operation of programs and serving as facilitators and evaluators. In most studies, knowledge and skills were measured as outcome variables of educational programs led by nurse educators. The roles of nurse educators were diverse in Korean medical institutions. Therefore, a program to enhance the competency of nurse educators is needed. Judging from the effects of nurse educators in Korean medical institutions, it is necessary to expand the nurse educator system, and additional research on nurse educators should be conducted.

  • In this study, we introduce a new design methodology of a granular-oriented self-organizing polynomial neural networks (GoSOPNNs) that is based on multi-layer perceptron with Context-based Polynomial Neurons (CPNs) or Polynomial Neurons (PNs). In contrast to the typical architectures encountered in polynomial neural networks (PNN), our main objective is to develop a methodological design strategy of GoSOPNNs as follows : (a) The 1st layer of the proposed network consists of Context-based Polynomial Neuron (CPN). In here, CPN is fully reflective of the structure encountered in numeric data which are granulated with the aid of Context-based Fuzzy C-Means (C-FCM) clustering method. The context-based clustering supporting the design of information granules is completed in the space of the input data while the build of the clusters is guided by a collection of some predefined fuzzy sets (so-called contexts) defined in the output space. (b) The proposed design procedure being applied at each layer of GoSOPNN leads to the selection of preferred nodes of the network (CPNs or PNs) whose local characteristics (such as the number of contexts, the number of clusters, a collection of the specific subset of input variables, and the order of the polynomial) can be easily adjusted. These options contribute to the flexibility as well as simplicity and compactness of the resulting architecture of the network. For the evaluation of performance of the proposed GoSOPNN network, we describe a detailed characteristic of the proposed model using a well-known learning machine data(Automobile Miles Per Gallon Data, Boston Housing Data, Medical Image System Data).

  • This study is about expressive aspects of subversive mimesis found in architectural design under 2nd Modernity. Architectural works under 2nd Modernity are described based on pseudo-scientific positivism and philosophical ontology of Deleuze. However, subversiveness found in works of arts by architects such as Rem Koolhaas present a few complexities to relay on such a description. This is about 'subversiveness' which absorbs the positive and negative factors of modernity which has been multi-layered as 'cultural capital'. This study aims to identify meta-phenomenon as well as the specific correlations between expression and purposes of any work of art that is presented in the form of subversiveness. To achieve this aim, this study approached with the concepts of appropriation and detournment based on Adorno's subversive mimesis concept. Meta-phenomena of architectural design methods occur from relations of three, which are social reality, artist, and work of art. This was connected to productivity of mimesis practice of self-reference and self-examination, which was then, summed up from the perspectives of appropriation in pure arts and d$\acute{e}$tournment of situationalists. Based on this work, subversive expressive characteristics of architecture under 2nd Modernity were framed from the perspectives of the absorption of cultural capital, reflection and negation, autonomy, instrumentality, and meta properties. In this way, this study found that Adorno's subversiveness should be effective for creative and methodological systemization in terms of interpretation of cognition, practice, and effect after materialization.

  • The aims of the study are first, in other to meet the demand for a new product design process, to review the prototype theory and to find out the conceptual structure of product aesthetics, which is another properly thought to be as important as the typical pattern in an effort to patch up the theory second to help designers overcome the limits of idea generation and create consumer oriented designs with a high success rate by setting up a new product design process that is established through the application of the aesthetically influential factor 'proportion'based on the preceeding studies that tested product aesthetics measuring devices. In other words, this study tries to find out product categories, making use of the prototype theory to introduce an ideal proportion for product design, recognizing the importance of proportion by conducting product pattern analysis: to create a differentiated method that can product consumer oriented designs, even if it only manipulate proportion and to establish a new design process that can systematically explain the methodology for various form generation that applies proportion. This study reviews the theoretical aspects of concepts pertaining to the above … and, based on them, empirically tests them by patting to use the programs, for proportion manipulation. This study was conducted in the following way: To begin with, this study takes out proportion out of some aesthetically influential factors that has a great impact on the way consumers prefer certain product designs and tries to see how proportion affects the consumer preference when consumers select a product. In addition, we could analyze the difference between the ideal proportion that consumers prefer and the traditional golden proportion produced through theoretical studies. The correlations between preferred proportion and ideal proportion, and preferred proportion and golden proportion could be shown. In order that we may create form variations through more detailed proportion manipulation on the basis of the ideal proportion verified as preferable, we again applied the proportion factor to the process utilizing PDS(proportion Distortion System). In the way the restraint of form generation could be pursued. All in all, this study makes an attempt to set up a design process to create new product forms through the application of Proportion.
