Over the years, cultural mapping methods have been used in several applications and contexts, for diverse cultural assets and to create new conditions for the development of local and regional resources. These methods were inspired by the development of big urban centres and regions, which have been the great engine of cultural mapping growth. The main objectives of the present paper are to provide a literature review on cultural mapping methodologies and to develop exploratory research on crowdsource tools on creative tourism which were applied to one Portuguese municipality in 2017. The research was supported by the implementation and integration of geographic information systems (GIS) and web mapping, which will become part of the solution for the growth of less developed territories and to make more interactive tourist activities. Web mapping's contribution to enhance crowd participation was measured via analysis of 12 digital photos shared through crowdsourcing. The originality of this research lies in the attempt to develop a new model for creative tourism, trying to extend the implementation of Web Mapping crowdsourcing to deprived low density territories. Results show how public participation can be amplified for the tourism market by crowdsourcing tools. These tools look very promising since they can help several members of the public at different ages to contribute to territorial knowledge, engage in activities, and collaborate through digital tools. It is a step to fulfil the lack of studies in this subject and it contributes to the way we think about future studies.

산림지역의 경우 도심지에 비해 무인항공사진측량 작업과정 중 하나인 지상기준점(ground control point, GCP) 측량이 제한적이며, 높은 산림 때문에 비가시권 비행으로 인해 안전문제가 발생한다. 이를 보완하기 위해 드론의 위치를 실시간으로 보정하는 RTK(real time kinematic) 드론과 지형정보를 기반으로 비행하는 3차원 비행 방식이 개발되고 있다. 본 연구는 산림지역에서 재난피해조사를 위한 드론의 활용방안을 제시하기 위해 1) GCP 측량을 통한 드론 맵핑(normal drone mapping), 2) 지형정보를 기반으로 비행하는 드론 맵핑(3D flight drone mapping), 3) RTK 드론을 이용한 드론 맵핑(RTK drone mapping) 3가지 방법을 통해 위치정확도를 평가하였으며, 그 결과 평면 위치오차는 2 cm, 높이오차는 13 cm 이내로 나타났다. 위치정확도 평가 후, 산사태 발생 면적을 계산하여 체적 값을 비교했을 때 세 가지 방법 모두 유사한 결과를 보였다. 본 연구에서는 3D flight drone mapping, RTK drone mapping을 통해 산림지역에서 드론 맵핑이 가지는 한계를 극복하고 재난피해조사의 활용 가능성을 확인하였다. 향후 다양하게 발생하는 재난상황을 감안하였을 때 재난지역의 여건에 따라 3가지 방법을 적절히 활용하면 보다 효과적인 피해조사를 수행할 수 있을 것으로 기대된다.

The purpose of this study is to investigate the effect of concept mapping strategies on the learner's achievement and their attitude change in science learning. The subject was 159 male students in a middle school in Seoul. Three experimental groups were instructed with different kinds of teaching methods about the unit of photosynthesis and digestive organs. Group I was instructed with traditional teaching method, GroupII was instructed with guided concept mapping strategy, GroupIII was instructed with student-centered concept mapping strategy. The major findings of this study are as follows. 1. Student-centered concept mapping strategy was observed effective at 0.05 significance level in achievement and retention. 2. Only student-centered concept mapping strategy changed students' attitude toward science learning positively. 3. It was observed that there was very significant correlation between the learning ability and science achievement (p<0.01). 4. Student-centered concept mapping strategy was found effective in upper learning-ability group, and guided concept mapping strategy in middle learning-ability group(p < 0.05). 5. Student-centered concept mapping strategy was effective to the groups of upper and middle learning-ability in changing students' attitude toward science learning(p < 0.05).

The approximate solvability of a generalized system for non-linear variational inequality in Hilbert spaces was studied, based on the convergence of projection methods. But little research was done in Banach space. The primary reason was that projection mapping lacked preferably property in Banach space. In this paper, we introduced the generalized projection methods. By using these methods, the results presented in this paper extended the main results of S. S. Chang [3] from Hilbert spaces to Banach space.

Objectives: We describe the development of a smoking and drinking prevention program for adolescents, using intervention mapping. Methods: The study sample consisted of 1,000 high school second-grade students from 6 high schools in Seoul. The PRECEDE model was applied for the needs assessment. We carried out a social diagnosis by assessing the factors such as the quality of life, happiness level, and satisfaction with school life; an epidemiological diagnosis on the perceived health status, stress levels, and priority of health issues; a behavioral diagnosis on the smoking and drinking rate and the intention to smoke and drink; and an educational diagnosis on knowledge, beliefs, attitudes, self-efficacy, outcome expectations, social norms and life skills. Results: The development process included a needs assessment, identifying factors that influence smoking and drinking among adolescents. Intention, knowledge, perceived norms, perceived benefit, perceived cost, perceived susceptibility, self-efficacy, and life skills were identified as determinants. Three performance objectives were formulated to describe what an individual needs to do in order to avoid smoking and drinking. Subsequently, we constructed an intervention matrix by crossing the performance objectives with the selected determinants. Each cell describes the learning objectives of the smoking and drinking prevention program. The program used methods from the transtheoretical model, such as consciousness raising, outcome expectations, self-reevaluation, self-liberation, counterconditioning, environmental reevaluation, and stimulus control. The program deals with the effects of smoking and drinking, self-improvement, decision making, understanding advertisements, communication skills, social relationships, and assertiveness. Conclusions: By using the process of intervention mapping, the program developer was able to ensure a systematical incorporation of empirical and new data and theories to guide the intervention design. Programs targeting other health-related behavior and other methods or strategies can also be developed using this intervention mapping process.

Motivation of this study is based on these two aspects: geologic uses of ASTER and application scheme of Spectral Mixture Analysis. This study aims at geologic mapping for mineral exploration using ASTER and LANDSAT 7 ETM+ at Mongolian plateau region by SMA. After basic pre-processing such as the normalization, geometric corrections and calibration of reflectance, related to endmembers selection and spectral signature deviation, both methods using spectral library and using PPI(Pixel Purity Index) are performed and compared on a given task. Based on these schemes, SMA is performed using LANDSAT 7 ETM+ and ASTER image. As the results, fraction map showing geologic rock types are enough to meet purposes such as geologic mapping and mineral potential mapping in the case of both uses of these different types of remotely sensed images. It concluded that this approach based on SMA with LANDSAT and ASTER is regarded as one of effective schemes for geologic remote sensing.
