Along with the increase of the quantity of data in various industries, the construction industry has also developed various systems focusing on collecting data related to the construction performance such as productivity and costs achieved in construction job sites. Numerous researchers worldwide have been focusing on developing efficient methodologies to analyze such data. However, applications of such methodologies have shown serious limitations on practical applications due to lack of data and difficulty in finding appropriate analytic methodologies which were capable of implementing significant insights. With development of information technology, the new trend in analytic methodologies has been introduced and steeply developed with the new name of "big data analysis" in various fields in academia and industry. The new concept of big data can be applied for significant analysis on various formats of construction data such as structured, semi-structured, or non-structured formats. This study investigates preliminary application methods based on data collected from actual construction site. This preliminary investigation in this study expects to assess fundamental feasibility of big data analytic applications in construction.

The purpose of this research was to provide basic data to the welfare policy for the aged by studying the relation of health concern, health behavior, and subjective health condition between the aged and the preliminary aged group. Subjects were composed of a total of 259 (116 males, 143 females) living in seoul, aged 50-64(preliminary old people) and over 65(old people), and they were asked to answer the survey Questionnaires The data were analyzed by descriptive statistics, chi-square test, and spearman's correlation coefficient. As a result of the study, the preliminary aged group was significant than the aged group in all three variables. In the relation of health concern and health behavior, there was significance both for the preliminary aged(p〈0.01) and the aged group(p〈0.001). Also, there was significance in the relation of health behavior and subjective health condition of two groups(p〈0.001). However, in the relation of subjective health condition and health concern, there was significance only for the aged group(p〈0.001). For the correlation among three variables, there was significance in the relation between health concern and health behavior and between health behavior and subjective health condition of the preliminary aged group(p〈0.01), but there was significance in the relation between health concern and health behavior and between health behavior and subjective health condition of the aged group(p〈0.01).

This study attempt to analyze the influence of the preliminary education on the Elderly's attitude for death and to present basic data for the death-preliminary education. The data were collected by administerial the Questionnaire interview with 169 the elderly who was 200 the elderly over 60 year old in silver colleges. The Questions was consists the awareness recognition of death, character, attitudes toward for death. The statistical methods used for the analysis were t-test, factor analysis. The results were the follows. There was no statistically significant relations between the fear of death and the general characteristics the elderly, but the old women felt more anxiety than old men. Especially, more aged, unhealthy the elderly felt it more and the lower educated or the single felt it more severely. The change in the attitude for death: They attitude for death was considerably changed after the preliminary education. Fears and anxiety about death were more reduced and the inevitability of death was accepted positively. This result showed the influence of the preliminary death education had positive affliction of the elderly's attitude for death. Accordingly, with the practice of the preliminary education we can release the elderly from the fear for death and guide them to live meaningly.

Purpose: The purpose of this study is a preliminary study to develop a comprehensive information avoidance scale that includes various search contexts. Research design, data and methodology: This study is a part of exploratory sequential design of mixed method for the development of information avoidance scale. Based on the themes derived from the analysis of the in-depth interview data collected in the qualitative research of the first stage of the study, 45 preliminary items on information search and avoidance were constructed. The factors related to information searching included information recognition, information seeking purpose, and information search expectations. Individual, information, time, and system factors were related to information avoidance. Pearson's correlation analysis was performed for the correlation between factor items, and Cronbach's alpha analysis was performed for the reliability analysis of the items. Exploratory factor analysis was applied to examine the construct validity of 35 items of information avoidance. Results: Among the information avoidance items, one of the less relevant among information purpose items, two information factor items, and one time factor item were excluded. Conclusions: A secondary survey should be conducted to confirm the validity and reliability of the scale composed of adjusted items (35) based on the results of exploratory factor analysis. The strength of this preliminary scale is that it was developed based on vivid qualitative data of ordinary people who had experiences of search and avoidance in various search contexts.

Sabah has experienced a rapid decline in the extent of forest cover. The precise impact of habitat loss on the conservation status of the plants of Sabah is uncertain. In this study we use the niche modelling algorithm MAXENT to construct preliminary, revised and final ecological niche models for Dipterocarpus lamellatus and Dipterocarpus ochraceus and combined these models with data on current land-use to derive conservation assessments for each species. Preliminary models were based on herbarium data alone. Ground surveys were conducted to evaluate the performance of these preliminary models, and a revised niche model was generated from the combined herbarium and ground survey data. The final model was obtained by constraining the predictions of the revised models by filters. The range overlap between the preliminary and revised models was 0.47 for D. lamellatus and 0.39 for D. ochraceus, suggesting poor agreement between them. There was substantial variation in estimates of habitat loss for D. ochraceus, among the preliminary, revised and constrained models, and this has the potential to lead to incorrect threat assessments. From these estimates of habitat loss, the historic distribution and estimates of population size we determine that both species should be classified as Critically Endangered under IUCN Red List guidelines. Our results suggest that ground-truthing of ecological niche models is essential, especially if the models are being used for conservation decision making.

최근 많은 연구자들은 서로 다른 영역에 저장된 센서 데이터를 이용한 조인 질의에 관심을 갖고 있다. 기존 기법은 예비 조인 조정자가 센서 노드로부터 시놉시스를 수집하고, 조인 질의 처리에 필요한 센서 데이터를 결정한다. 기지국은 전체 데이터를 수집하는 대신 일부 센서 데이터를 수집하여 최종 조인 처리를 수행한다. 하지만, 예비 조인을 수행하는 과정에서 통신 오버헤드를 발생시키는 단점을 가지고 있다. 본 논문에서는 이와 같은 문제점을 해결하는 새로운 에너지 효율적인 인-네트워크 조인 기법을 제안한다. 제안하는 기법은 네트워크 내부에서 예비 조인 조정자를 선정한다. 예비 조인 조정자는 조인의 초기 단계에서 조인 결과에 포함되지 않는 데이터를 제거하고 센서 데이터의 압축을 수행한다. 기지국은 압축된 데이터의 일부와 데이터 압축을 위한 인코딩 테이블을 수집하고 조인 결과를 결정한다. 그 결과, 제안하는 기법은 예비 조인 처리를 위한 통신 비용을 줄이고 네트워크 수명을 연장시킨다.
