The purpose of our study is to analyze the effect of socio-economic status on the diet pattern of Korean adults. Raw data from the fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) were used, and finally 11,700 adults were analyzed as subjects. Results in consideration of the socio-economic status of the subjects, a linear trend was observed in men in which the odds ratio of having lunch (p for trend=0.006) and dinner (p for trend=0.0317) decreased as the level of education went down. In diet frequency, a decreasing trend (p for trend=0.0328) was observed in which the odds ratio of having 3 meals a day reduced as the household income lowered. For women, a linear trend (p for trend=0.0012) was observed in which the frequency of dinner decreased as the level of education became lower. A falling trend in the rate of having 3 meals a day was also observed (p for trend=0.0135). Our study analyzed the characteristics of the diet patterns of individuals according to their socio-economic status with the purpose of suggesting guidelines for correcting. To prevent this, we will need education and awareness and public attention for the practice of correct eating habits.

Our research is aimed at predicting recent trend and leading technology for the future and providing optimal Nano technology trend information by analyzing Nano technology trend. Under recent global market situation, Users' needs and the technology to meet these needs are changing in real time. At this point, Nano technology also needs measures to reduce cost and enhance efficiency in order not to fall behind the times. Therefore, research like trend analysis which uses search data to satisfy both aspects is required. This research consists of four steps. We collect data and select keywords in step 1, detect trends based on frequency and create visualization in step 2, and perform analysis using data mining in step 3. This research can be used to look for changes of trend from three perspectives. This research conducted analysis on changes of trend in terms of major classification, Nano technology of 30's, and key words which consist of relevant Nano technology. Second, it is possible to provide real-time information. Trend analysis using search data can provide information depending on the continuously changing market situation due to the real-time information which search data includes. Third, through comparative analysis it is possible to establish a useful corporate policy and strategy by apprehending the trend of the United States which has relatively advanced Nano technology. Therefore, trend analysis using search data like this research can suggest proper direction of policy which respond to market change in a real time, can be used as reference material, and can help reduce cost.

본 연구에서는 주가 결정 방법이 주가 경향 예측에 미치는 영향을 확인하기 위한 분석을 수행한다. 주식시장에서 성공적인 투자를 위해서는 주가의 상승과 하락을 정확하게 예측하는 것이 큰 도움이 되므로 주가 경향 예측에 관해 많은 연구가 진행되고 있다. 예를 들어 근래에는 SNS나 뉴스의 내용을 텍스트 마이닝을 이용하여 분석하고, 이를 이용한 주가 등락의 예측 방법이 제안되었으며 다양한 기계학습 기법들이 활용되고 있다. 그러나 주가의 경향을 '상승' 또는 '하락'으로 결정하는 방법은 제대로 분석된 적 없으며 일반적으로 쓰던 방법을 답습하고 있다. 이에 본 논문에서는 주가 경향 결정 방법을 이동평균을 이용해 일반화하고 주가 경향 결정 방법이 예측 정확도에 미치는 영향을 분석한다. 분석 결과, 다음 날의 주가 경향을 예측하는 경우, 주가 경향 결정방법에 따라 예측 정확도가 47%까지 차이가 남을 발견하였다. 또한 경향 결정에 사용되는 기준값 윈도우의 크기와 예측의 정확도는 비례 관계이며, 대상값 윈도우의 크기와 정확도는 반비례 관례임을 알 수 있었다.

제주도 지하수관측망의 지하수위 측정 자료에 대하여 모수 및 비모수 경향분석을 수행하였다. 분석대상은 2001년부터 1년 이상 관측된 관측정으로 총 106개 관측정 중 94개가 이에 해당된다. 모수분석은 일평균 및 월중앙값을 이용한 선형회귀분석을 실시하였으며 비모수분석은 월중앙값에 대해 Mann-Kendall trend test와 Sen's trend test를 적용하였다. 선형회귀분석 결과 일평균값에 대하여 58.5%가 감소경향을 나타났으며 월중앙간에 대해서는 79.8%가 감소하는 경향을 보였다. Mann-Kendall trend test와 Sen's trend test를 신뢰수준 95%와 99%로 실시한 결과 두 분석 모두 일치하는 결과를 보였다. 95% 신뢰수준에서는 32%가 감소경향을 보였으며 3%가 증가경향을 나타냈고, 나머지 65%는 경향성이 나타나지 않았다. 또 99%신뢰수준에서는 16%가 감소경향을 보였으며 2%가 증가경향을 나타냈고 그리고 나머지 82%에서는 경향성이 없는 것으로 나타났다. 수위하강이 우세하게 나타난 지역은 제주도 북서부 및 남서부의 해안지역으로 도시 및 관광지에서의 다량의 지하수 양수와 관련 있는 것으로 사료된다.

We examined long-term variations in sea surface temperature (SST) and annual amplitudes of SST around the Korean Peninsula. Two SST data sets with data periods of approximately 51 years and longer than 100 years, respectively, were obtained from the National Institute of Fisheries Science and Japan Meteorological Agency. SST of Korean waters clearly increased during last 51 years (1968-2018), which was 2.5 times higher than the global trend. This significant increasing trend was caused by the dominant increasing SST trend during winter. However, a negative and positive SST anomaly frequently appeared during winter and summer, respectively, in a recent decade. These features of seasonal SST variation have changed the annual amplitude of SST, and resulted in a drastically increasing trend after 2009. Using the longer SST data set, it was revealed that the decreasing SST trend in winter began in the 2000s and the increasing SST trend in summer bagan in the 1990s. During a recent decade, there was a distinctive SST increase in summer, whereas a clear decrease in winter. In summary, the annual amplitude of SST around the Korean Peninsula significantly changed from a decreasing trend to an increasing trend during a recent decade.

The purpose of this study is to come up with ways that cooperate between on-line game design and fashion design by analyzing trend color and on-line game character's costume color in on-line game. As for the research methodology, First, on-line games were selected with reference to www.ranky.com. Second, 2009 SS trend color palettes suggested by Copenhagen International Fashion Fair was used as a criterion of fashion trend. Third, on-line game character's costume colors were analyzed in relation to the degree of reflection of trend and the game character's type. The results are as follows. Each on-line game character costume's colors were made in accordance with typical character types. But we can find a one-to-one correspondence between fashion trend colors and game character costume's colors. That's because both trends and character types are the results of the continuing interactions between human-beings and societies. In comparison with fashion trend colors, game character costume colors are partly raw and inharmonious. Therefore, it is necessary to apply fashion trend color in game character costume design for enhancing competitiveness in the world market.
