Objectives: To identify changes in the subjects and methods of Herbal Medicine Consumption Survey, and analyze trend of the key results Methods: The population, methods, and items of the basic reports of all Surveys on Consumption of Herbal Medicine(HM) were organized in a time-series manner. The analysis items were trend in the purchase of standardized HM; consumption value share, and price of prepared HM; type of herbal dispensary; and awareness of HM policy in Koran Medicine(KM) institutions. Results: The price of HM preparations showed an upward trend in 2011, 2014, and 2017 surveys, and decreased in the 2020 survey. However, despite this recent decrease, the 2021 survey also saw the highest proportion of HM users reporting that price of herbal decoction is expensive. Furthermore, the demand for expanded coverage of herbal decoction was the greatest for the expansion of health insurance benefits. Efforts such as adjusting the number of covered diseases and the cost of health insurance coverage would be necessary. Regarding decoction dispensaries the proportion of HM hospitals using only extramural herbal dispensaries increased. Finally, the consumption of HM and the size of the HM industry has continued to expand due to the large-scale branding of KM institutions and the expansion of health insurance coverage. Conclusion: Future surveys must standardize and unify the items for the time-series continuity and compare the results with government statistics reports on HM to increase reliability. Moreover, specialized survey items may be developed for KM, to establish a better and efficient distribution system for domestic HMs.

낙동강 유역에 조성된 신규습지에서 서식환경에 대한 어류의 분포 특성을 평가하고, 이를 기반으로 한 관리방안 도출을 위해 42개 습지에서 환경요인의 측정과 어류 조사를 시행하였다. 조사 기간 동안 총 30종의 어류가 출현하였으며, 이 중에서 배스(Micropterus salmoides)와 블루길(Lepomis macrochirus)과 같은 외래어종의 비율이 상대적으로 높았다. 특히, 밀어(Rhinogobius brunneus)나 끄리(Opsariichthys uncirostris amurensis), 피라미(Zacco platypus) 등의 어류는 흐름이 있는 환경을 선호하기 때문에 배스가 우점하는 습지(정체수역)에서 상대적으로 낮은 밀도를 가지는 것으로 사료된다. SOM (Self-Organizing Map)을 활용한 패턴분석 결과, 각 습지의 서식환경 특성에 따라 어류 종의 출현빈도가 상이한 것으로 분석되었다. 어류 종의 분포는 각 습지의 수심 변화와 수생식물 피도에 민감하게 영향 받는 것으로 나타났으며, 수온이나 pH, 용존산소 등의 이화학적 요인 변화에 대한 영향은 적었다. 특히 수생식물의 피도는 어류의 종다양성이나 밀도에 강한 영향을 주는 것으로 분석되었으며, 수변식생이 부족한 습지에서는 어류가 적은 풍부도와 다양성을 가지는 것으로 나타났다. 본 연구 결과를 기반으로 평가할 때 어류 등의 생물다양성 증진을 위해 호안사면의 높은 인공성이나 수변식생의 부족한 습지 등은 개선이 필요할 것으로 사료되며, 건강성 확보를 위한 지속가능한 관리방안이 마련되어야 할 것으로 판단된다.

Purpose - This study aims to explore how a combination of the advertisement presentation vividness and consumers' regulatory focus affects choice. In addition, it seeks to the understanding for the psychological process by using consumers' response with experimental designs. Research design, data, and methodology - This research conducted two experiments based on the scenario. Specifically, Experiment 1 used a 2 (vividness of advertisement presentation: picture vs. word) × 2 (regulatory focus: prevention focus vs. promotion focus) between-subjects design. Experiment 2 used a 2 (vividness of advertisement presentation: detailed description vs. less detailed description) × 2 (regulatory focus: prevention focus vs. promotion focus) between-subjects design. Results - Two studies showed that prevention-focused individuals, when presented with a vivid presentation, were more likely to choose the advertised option compared with advertisements presented less vividly appearance. In contrast, promotion-focused individuals showed no difference in choice shares regardless of advertisement presentation vividness. In addition, these effects were mediated by the imagery toward the advertised information. Conclusions - The current research found how consumers' inherent motivation affects the extent of imagery in a purchase decision and a new perspective to previous studies with regards to regulatory focus. Further, this research suggested new advertisement strategies to corporations.

Purpose - The purpose of this study is to measure the effect on the attributes for store selection and Korean government regulations for large retailers on consumption emotion. Research Design, Data, and Methodology - Using SPSS ver.22, factor analysis & Cronbach's alpha, correlation, and regression test were performed. The total of 287 questionnaires were used for the analysis Result - Familiarity, perceived price, and perceived image have a positive effect on consumption emotion, but perceived quality & service did not. The Consumption emotion had a positive effect on traditional market revisit intentions. Retail regulation preference has a mediate effect between consumption emotion and familiarity & perceived price. Retail regulation preference also has a mediate effect between consumption emotion and traditional market revisit intension. Conclusion - Relationship marketing with sincerity is very important to keep familiarity, perceived price and image. People's consumption trend was changed due to dual career couple and heavy traffic jam in big cities. Therefore, a retail regulation cannot be a right solution for revitalizing traditional markets. So we need to find out an actual situation and design a win-win strategy between large retailers and traditional market.

With the effectuation of Kyoto Protocol, one of the important movement throughout the world is reducing the emission of greenhouse gas which is the main reason of making global warming. The actual factor of greenhouse gas is CO2, and in year of 2002 20% of total CO2 emission was produced only through transportation throughout the South Korea. In the contrary, the recycling of municipal wastes in South Korea was 44.0% in 2002, but it will be targeted upto 53.5% in 2011. All of these show environment-conscious logistics should be implemented together throughout the each stage of distribution with the development of product and service. This study applied survey research for the activities affecting to the emission of CO2 and packaging wastes produced from transportation and packaging stages in logistics area. For this, survey questionary was constructed with five specific areas - strategy, transportation & distribution, custody, packaging, and information. Based on the 148 returned survey questionaries, this study analyzed 52 categories and finally suggests necessary modal shift, collaboration & co-operation in logistics, LCA(life-cycle assessment), and other promoting policies for the environment-conscious logistics in effective way.

A hill-sliding technique was devised to extract Gaussian clusters from the multivariate probability density estimates of sample data for the first step of iterative unsupervised classification. The underlying assumption in this approach was that each cluster possessed a unimodal normal distribution. The key idea was that a clustering function proposed could distinguish elements of a cluster under formation from the rest in the feature space. Initial clusters were extracted one by one according to the hill-sliding tactics. A dimensionless cluster compactness parameter was proposed as a universal measure of cluster goodness and used satisfactorily in test runs with Landsat multispectral scanner (MSS) data. The normalized divergence, defined by the cluster divergence divided by the entropy of the entire sample data, was utilized as a general separability measure between clusters. An overall clustering objective function was set forth in terms of cluster covariance matrices, from which the cluster compactness measure could be deduced. Minimal improvement of initial data partitioning was evaluated by this objective function in eliminating scattered sparse data points. The hill-sliding clustering technique developed herein has the potential applicability to decomposition of any multivariate mixture distribution into a number of unimodal distributions when an appropriate diatribution function to the data set is employed.

Quantitative forecasting methods based on spatial data and geographic information system have been used in predicting the landslide location. This study compared the simulated results of logistic, Bayesian, and maximum entropy models to understand the uncertainties of each model and identify the main factors that influence landslide. The study area is Boeun gun where 388 landslides occurred in the year of 1998. The verification results showed that the AUC of the three models was 0.84. However, the landslide susceptibility distribution of Maxent model was different from those of the other two models. With the same landslide occurrence data, the result of high susceptible area in Maxent model is smaller than Logistic or Bayesian. Maxent model, however, proved to be more efficient in predicting landslide than the other two models. In Maxent's simulations, the responsible factors for landslide susceptibility are timber age class, land cover, timber diameter, crown closure, and soil drainage. The results suggest that it is necessary to consider the possibility of overestimation when using Logistic or Bayesian model, and forest management around the study area can be an effective way to minimize landslide possibility.
