  • The growing popularity of Group Decision Support Systems (GDSS) has been supported by, and has given rise to, a burgeoning academic literature on GDSS since the mid-1980s. Although there is a growing body of laboratory experiment findings, the results are inconclusive. Field studies in real organization settings show all the more different results form the experimental studies. This paper systematically reviews the existing case, field, and laboratory decision room type GDSS studies. It, then, explores the plausible reasons for the inconsistent findings across the laboratory studies, and especially between field and laboratory research. It suggests five main factors for the inconsistent findings in previous GDSS research: contextual pressures, tasks, group characteristics, technical configurations, and comparability of measures.

  • In Korea, consumer researches have been accomplished in the field of family economics or business management individually. The field of consumer studies progressed in both sides of quantity and quality since the establishment of the Korean Society of Consumer Studies(KSCS). The field of consumer studies is moving toward an uni-disciplinary stage from an interdisciplinary stage. In this time, it is very meaningful to review the research trend in consumer science and to look out the future prospect. This study reviewed and analyzed all of the papers published in Journal of Korean Home Economics Association from 1980 to 1999, Journal of Korean Home Management Association from 1984 to 1999 and Journal of Consumer Studies from 1990 to 1999.

  • 일반적으로 지역학 연구를 수행하는데 있어 연구 동향을 파악하는 것은 매우 중요하다. 그러나 지역학의 연구 분야는 매우 다양하며, 모든 지역학 연구 분야에 대한 연구가 동시에 진행되는 것은 매우 어렵다. 이로 인해 지역학연구는 시대에 따라 연구 분야 및 연구 동향이 변화 하였다. 이와 함께 지역학의 연구 동향을 이해하려는 관심이 꾸준히 증가되고 있다. 본 논문에서는 국내의 지중해지역 연구를 대상으로 동시 출현 키워드를 기반으로 연구 동향을 분석한다. 이를 위하여 국내 지중해지역 연구의 대표 학술지인 『지중해지역연구』에 게재된 논문들을 대상으로 논문 유형 분석 및 키워드를 추출하여 정제 과정을 거쳐 동시 출현 키워드를 생성하였다. 세부적으로 논문의 유형 분석을 통해 기본적인 동향 분석을 수행하였고, 논문의 동시 출현 키워드를 이용하여 단순 정량 분석보다 심층적인 분석을 수행하고, 동시출현 키워드를 통해 생성된 네트워크 그래프 형태의 시각화를 통해 분석을 수행한다.

  • Objective : The purpose of this study is to identify the trends of vibration(or wave) therapy in Korea, to actively utilize vibration(or wave) therapy, and to help research activities of vibration therapy in Korean Medicine. Methods : The following Korean words "진동기", "진동요법", "진동운동", "진동치료", "파동요법", "파동운동", "파동치료" were searched on three specialized search sites (RISS, NAL, DBpia). Trends of vibration therapy were analyzed through the selected researches suitable for this study among these searched researches in an overview format. Results : 1. A total of 8,116 studies were searched and a total of 365 studies were finally selected 2. From 2000 to 2019, when research began to increase in earnest, there were 17.45±10.28 studies per year, and the AGR(Average Annual Growth Rate) was 11.92%. 3. In the main field of research, the 'Medicine and Pharmacy' was the largest with 147(40.16%) studies. In the Middle Field, the 'Kinesiology' was the largest with 99(27.05%) studies. In the study design, 'RCT(Randomized Controlled trial)' was the largest with 138(47.75%) studies. In the Age Group, 'Youth' was the largest with 126(48.84%) studies. 4. The average of the number of participants was 24.90±17.44. 5. The most used Intervention was the 'WBV(Whole Body Vibration)' with 177(61.25%) studies. 6. The average of Intervention Period was 5.99±4.14 weeks, while the maximum was 36 weeks. 7. The journal that published the most research papers is 'K. J. of Sports Science(체육과학연구;13)', and the society is 'Rehabilitation Engineering And Assistive Technology Society of Korea(한국재활복지공학회; 14)'. The University that published the most dissertations is 'Sahmyook University(11)'. 8. The authors who published the most studies are Ju-Hwan O(8) as the main author and Tae Kyu Kwon(18) as the co-author (including the thesis Director). In an integrated analysis of the authors and co-authors, Tae Kyu Kwon published the most numerous studies(19) Conclusions : 1. The study of vibration or wave therapy has been increasing noticeably every year. 2. The major academic Fields studying vibration or wave therapy are the 'Kinesiologic Field', 'Physical Therapy Field', and 'Biomedical Engineering Field'. 3. The most chosen method of study design on vibration or wave treatment was 'RCT', and there was no significant change in the annual presentation rate. 4. Types of vibration or wave therapy could be classified as 'LVS(Local Vibration Stimulation)', 'WBV(Whole Body Vibration)', 'MV(Micro Vibration)', 'BV(Bio Vibration)' and 'SWV(Sound Wave Vibration)', and the study on Whole Body Vibration is most active. 5. Most of the studies of vibration or wave therapy were on musculoskeletal systems, but there were very few studies on internal diseases.

  • The purpose of this study was to investigate differences in social play, cognitive play, and social-cognitive play patterns as related to young children's field independence-dependence cognitive styles. Sixteen field independent and sixteen field dependent children were selected from a group of 79 young children with the use of Preschool Embedded Figures Test(PEFT). Their social play, cognitive play, and social-cognitive play patterns were observed. The data collected for this study were analyzed by using SPSS/$PC^+$; frequency, percentage and ${\chi}^2$ test. The results of this study were that (1) difference of social play patterns as related to young children's field independence-dependence cognitive styles was not found, (2) differences were found in cognitive play patterns as related to young children's field independence-dependence cognitive styles, and (3) differences were found in social-cognitive play pattern as related to young children's field independence-dependence cognitive styles.

  • 자기장에 대하여 우리는 부지불식간에 많이 노출되고 있고 이와 관련된 영향에 대한 연구도 많이 진행되어 왔다. 역학 조사를 통한 연구도 있고, 실험실 수준의 연구도 있다. 실험실 수준의 연구의 경우, 인위적인 자기장 생성을 통해서 세포에 자극을 가하고 이에 대한 영향을 관찰한다. 세포 실험에서 많이 사용되는 주파수와 파형은 다양하지만, 그 크기는 보통 10G 내외이다. 지구 자계의 크기인 300-400mG 정도와 비교하면 크다고 할 수 없으나, 오래 전부터 이 환경에 적응되어 왔기 때문에 인위적으로 가하는 자기장 세기의 3-4%의 크기지만 무시할 수 없다. 본 연구에서는 주변 자기장에 대한 영향을 고려하여 실험할 수 있도록 양방향 정자계 생성이 가능한 자기장 발생 장치를 설계하고 구현하였다. 제안된 시스템으로 조절 가능한 정자계의 크기는 ${\pm}500mG({\pm}50uT)$까지이며 최소 ${\pm}5mG({\pm}0.5uT)$까지 주변 자기장을 실시간으로 상쇄시킬 수 있었다.

  • Irreversible magnetization between the zero-field-cooled (ZFC) and field-cooled (FC) states in $Y_{1-x}Sr_xMnO_3$ (x=0 and 0.2) was investigated. $YMnO_3$ and $Y_{0.8}Sr_{0.2}MnO_3$ have a hexagonal structure and the lattice parameter a decreases from 7.4408 ${\AA}$ to 7.4327 ${\AA}$ while c increases from 12.2244 ${\AA}$ to 12.2287 ${\AA}$ for $YMnO_3$ and $Y_{0.8}Sr_{0.2}MnO_3$, respectively. An anomaly is observed at around 74 K in ZFC and FC magnetization measurements for $YMnO_3$, whereas in $Y_{0.8}Sr_{0.2}MnO_3$ the ${\sigma}_{ZFC}$ and ${\sigma}_{FC}$ are split at low temperature, indicating glass-like behavior.

  • Wire codes, introduced by Wertheimer and Leeper, are interesting largely because several case-control studies have reported associations between them and certain types of cancers, including childhood leukemia. This paper is concerned with the reliability of wire codes as a surrogate for residential electric and magnetic field, divided into four categories based on the electrical wiring within 40m of homes. To examine the correlation between spot measurements and wire codes, EMF was measured by using HI-3604 and classified by wire codes. The correlation between long-transformed RMS of magnetic field and wire codes was 0.81. But the correlation between log-transformed RMS of electric field and wire codes was 0.27. The results led us to determine a four category from of the Wertheimer and Leeper code that 1) may be useful in domestic epidemiological studies and 2) is not suitable for electric field exposure. Thus, the critical point of exposure assessment in residential magnetic field is to classify a wire code precisely.

  • 샌프란시스코 해양방류의 근영역거동에 대한 현장 및 실험연구는 유량조건과 해양조건을 만족하는 것으로 다공확산관에 의한 해양방류의 전형적인 유형이라 할 수 있다. 특히 실험자료들은 현장시험을 모의한 밀도층을 갖는 견인수조로부터 얻어진 것이다. 이들 자료를 이용한 폐수영역거동의 모형연구는 최소희석률, 회종희석높이 및 희석두께를 수리 및 수학적 모형인 UM모형, UDKHDEN모형, RSB모형과 CORMIX 모형을 이용한 예측치와 실측치를 비교 분석하였다. 수리모형연구는 현장에서 관측된 주요현상들을 재현할 수 있었다. 또한 현장시범이나 수학적모형으로부터 얻을 수 없는 다공확산관의 혼합기능을 관찰 할 수 있다.
