  • Objectives The purpose of this study was to evaluate quality of reporting of intervention studies on Sasang Constitutional diet (SCD) based on the Consolidated Standards for Reporting of Trials (CONSORT) and Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) statements. Methods We searched for Randomized controlled trials (RCT) and Non randomized studies for intervention (NRSI) on SCD in 4 databases and other sources, selected them by the inclusion criteria, and then evaluated quality of reporting of them. Results 1. A total of 10 studies (1 RCT and 9 NRSI) from 1999 to 2006 were selected and evaluated. The detailed items of up to 78%, at least 40%, and median value of 59% in the CONSORT and TREND statements were not reported. 2. One RCT was reporting 4 (11%) sufficiently, and 4 (11%) insufficiently among the 37 detailed items in the CONSORT statement while it was not reporting 29 (78%) items. 3. Nine NRSI were reporting 7 (12%) items sufficiently, and 2 (3%) items insufficiently among the 58 detailed items in the TREND statement while they were not reporting 15 (26%) items. Twenty (34%) items in the TREND statement were reported in some papers but not in more than half. Conclusions The quality of reporting of intervention studies on SCD has been assessed to be generally low. Subsequent researchers are recommended to select an appropriate statement for research design, and use it as a checklist from the time of designing the study to the time of reporting.

  • It is reported that the segmental feature based recognition system shows better results than conventional feature based system in the previous studies. On the other hand, the various studies of combining neural network and hidden Markov models within a single system are done with expectations that it may potentially combine the advantages of both systems. With the influence of these studies, tandem approach was presented to use neural network as the classifier and hidden Markov models as the decoder. In this paper, we applied the trend information of segmental features to tandem architecture and used posterior probabilities, which are the output of neural network, as inputs of recognition system. The experiments are performed on Auroral database to examine the potentiality of the trend feature based tandem architecture. From the results, the proposed system outperforms on very low SNR environments. Consequently, we argue that the trend information on tandem architecture can be additionally used for traditional MFCC features.

  • This study aimed to understand whether or not academic outcomes in digital studies shown in detailed field of costume were generated appropriately according to the development of digital technology by analyzing contents of studies in the digital-related studies, which were conducted with a background of the digital age. First, as a result of frequency of digital-related theses by the age of 'Internet Age(1994-2000)', 'Digital Age(2000-2009)', and 'Smart Life Age(After 2010)', which were classified according to the digital environmental changes, the number of theses increased drastically based on the transition point of each age. Second, representative keywords that appeared in each age included 'digital' and 'Internet' in the Internet Age, and 'digital', 'smart', 'Internet', '3D', and 'wearable' were shown in the 'Digital Age' and 'Smart Life Age'. Third, results of analysis according to the field of costume show that relevant studies were conducted in three fields of marketing/information, clothing construction and fashion design in the Internet Age, whereas the Digital Age produced relevant studies in all fields, and Smart Life Age was characterized by increase in studies in the field of fashion design and clothing construction. Fourth, results of analysis according to the contents of study show that relevant studies in the Internet Age were shown only in two subjects of 'preliminary study and trend of study' and 'studies using technical programs', and 'preliminary study and trend of study' decreased, but relevant studies in other fields of subject increased in the Smart Life Age. As shown above, relevant studies appeared as various subjects in many different detailed fields of costume in costume studies according to the stream of the Smart Life Age, which is growing fast recently, and is considered an inspiring result for development of studies in the field of costume according to the environment of the age.

  • Objectives: The present study examines the domestic trend of Chuna manual therapy on cervical spinal disorders in Korea. Methods: We investigated the studies on Chuna manual therapy for cervical spinal disorders via searching 6 Korean web databases. As a result, 51 research papers were found to be analyzed according to their published year, published institution, the titles of journals, the types of study, the techniques of Chuna, the instruments for assessment, the Chuna technique and the number of the treatment trials by the cases of cervical spinal disorders and ethical approvals. Results: The number of the research papers published tended to increase every year. The studies on Chuna manual therapy for cervical spinal disorders were mainly published in The Journal of Korea CHUNA Manual Medicine for Spine & Nerves. The most frequently adopted technique of Chuna in the examined studies was Chuna spine manipulation therapy - cervical spine technique. Visual analogue scale (VAS), neck disability index(NDI) were used as primary means of assessments. The ethical problems of the examined studies needed to be improved. Conclusions: Reviewing the domestic trend of studies on Chuna manual therapy for cervical spinal disorders and examining the strong and weak points of those treatments are essential for the future studies. It is anticipated that this review benefits the future in-depth study on the treatments for Chuna in Korean medicine.

  • In longitudinal studies, outcomes are repeatedly measured over time for each subject. It is common to have missing values or dropouts for longitudinal data. In this study time trend in longitudinal data with dropouts is of concern. The confounding of time trend with dropout process is investigated through simulation studies. Some simulation results are reported for binary responses as well as continuous responses with patterns of dropouts varying. It has been found that time trend is not confounded with random dropout process for binary responses when it is estimated using GEE.

  • There are various form of public elements in modern urban space. These public elements mingle with sociocultural elements which consist of each city, determining urban environment's image. Especially, since the social value of design becomes important, the social role of public design has been emphasized as an effective value for public interest and environment. It is just about 10 years since design mind in the public sector has been made domestically. Even though domestic public design has been studied not so long, it has developed with radical change of social culture and science technology. This study targets public environment in modern dense urban space. Also, it grasps the trend of public design studies through analysing and documentary survey of the existing studies, and based on that result, aims at presenting the direction that domestic public design studies should progress. This study selected 253 theses(1989.6~2015.11) by collecting primary, secondary data about public design studies, and implemented overall meta-analysing about the trend of domestic public design studies. As a result, public design has been studied intensively in the field of design about environment, architecture, etc. The trend analyzing of study purpose and keyword has a tendency which is weighted towards exploratory study focused on suggestion and development about object and realm of public design. The trend analyzing of study area tends to study overall part of public space or public facility rather than specific area and object. The most parts of studies analyze domestic area, especially Seoul metropolitan area. Also, the study method weighted in favor of some qualitative analysis has been utilized.

  • This study began to classify the studies on 'culture' in the field of environmental design overall. The classifying process adopted not the approach to preselect the criteria but the phenomenological inductive approach and content analysis method focusing on environmental design in order to understand which place the environmental design had taken. As a result, following aspects were reviewed: what is the area in which the studies on culture is made under the environmental design; what is the trend of using the word 'culture' in terms of logical connection; what is the level of approach to culture from the viewpoint of search, correspondence or application stage. On the whole, followings were drawn as conclusions. First, the interest of the studies on culture has been increased with time especially in the field of interior design. Second, the word 'culture' has become to be used a lot as 'cultural', and was used together with traditional, enterprise and material. Lastly, culture was studied at a starting point by and large. Although the papers, the objects of this study, are confined to five kinds of journals, the analysis of them is helpful to preestimate the trend of studies on culture because they have propensity to lead the international professional academic world.
