The intent of this study is to propose a method for appraisal of the indoor thermal environment of apartment housing by measuring physical factors and residents' response to questionnaire survey. The experiments were performed on eight houses each in summer (August 18 through 31,1995) and winer (february 16 through 20,1996). It included measurements of indoor air temperature, globe temperature, relative humidity, and CO2 concentration. The questionnaire surveys were performed each in summer (July 16 through 20, 1996) and winer (February 13 through 16, 1996). And 248 cases in summer and 297 cases in winter were used in analysis. These questionnaire surveys asked residents' response about thermal sensation, humidity sensation, sense of air freshness regarding the indoor thermal environment. data acquired through the experiments and questionnaire surveys were then transferred to scales that allowed relative comparison, and measured to an appraisal standard chart. Appraisal tools included appraisal charts and radar charts. Indoor thermal environment was judged to be positive according to experiments, but residents appraised the thermal environment to be average. This difference between the two can be found in the strict standards by which residents judge the thermal environment of their apartments.

Current and planned deep multicolor wide-area cosmological surveys will map in detail the spatial distribution of galaxies and quasars over unprecedented volumes, and provide a number of objects with photometric redshifts more than an order of magnitude bigger than that of spectroscopic redshifts. Photometric information is statistically more significant for studying cosmological evolution, dark energy, and the expansion history of the universe at a fraction of the cost of a full spectroscopic survey, but intrinsically carries a bias due to noise in the distance estimates. We provide convolution- and deconvolution-based algorithms capable of removing this bias -- thus able to exploit the full cosmological information -- in order to reconstruct intrinsic distributions and correlations between distance-dependent quantities. We then show some direct applications of our techniques to the VIMOS Public Extragalactic Redshift Survey (VIPERS) and the Sloan Digital Sky Survey (SDSS) datasets. Our methods impact a broader range of studies, when at least one distance-dependent quantity is involved; hence, they will be useful for upcoming large-volume surveys, some of which will only have photometric information.

NASA, NSF and USGS jointly conducted airborne LIDAR surveys to acquire numerous surface points with high densities over the Antarctic Dry Valleys and its vicinity, The huge set of these points retains two characteristics undesirable for DEM generation, which are unusually high blunder ratio and large variation of the local point densities. Hence, in order to not only reduce the undesirable effects due to these characteristics but also process the huge number of points within reasonable limits of time and resources, we developed an efficient, robust, nearly automatic approach to DEM generation. This paper reports about the application of this approach to generating high-resolution precise DEMs from the Antarctic LIDAR surveys and the evaluation of their accuracy.

Objectives: In Korea, there are many kinds of evaluations for medical institutions. However, evaluations are increasingly burdensome for medical institutions because evaluation agencies, evaluation timing, and evaluation methods are different. The purpose of this study is to improve the efficiency of evaluation for medical institutions and ultimately to provide quality medical services to patients. Methods: In this study, 2,310 indicators of 19 kinds of evaluation for medical institutions were analyzed. Results: 1,424 indicators were available for on-site surveys and 886 indicators were not available for on-site surveys. There were 4 kinds of evaluation that can be integrated in total, 12 kinds of evaluation that can be integrated partially, and 3 kinds of evaluation that need to maintain the current evaluation system. Conclusion: In order to provide patient-centered quality medical services through reduction of burden due to the evaluation for medical institutions, it is necessary to deeply discuss the efficiency of evaluation integration and result utilization.

Land (scape) ecology is a trans-disciplinary science studying the related systems at the earth surface, in their visual, structural and functional aspects. it serves as an umbrella under which abiotic and biotic sciences, in an integrated way, study the for each relevant land attributes and their interrelations. The spatial aspects of these relations have a special interest. Landscape ecology my have a pure scientific purpose, but usually is executed in an applied context, related to land evaluation for land use and conservation. Depending on the aim and application of the study, one of the land attributes may get special attention. Vegetation mapping may contribute to landscape ecological study but also benefit from it especially in case of reconnaissance surveys. This is because in less detailed surveys of any land attribute, like land form, soil, vegetation, one must necessarily apply landscape ecological principles in the survey methodology, including remote sensing.

Hofstede cultural value model is one of the most influential model for cross-cultural studies to measure national difference. In this study, we examine that Hofstede Cultural Dimensions can be measured by World Value Surveys. Selected WVS questions for 31 measurable countries after Exploratory Factor Analysis(EFA) and Confirmatory Factor Analysis(CFA), approved valid through empirical analysis. It is applicable that Individualism values(IND) has related to 2 questionnaires including life satisfaction, Power Distance values(PDI) to 2 questionnaires about political action(Signing a petition and Joining in boycotts), Masculinity values(MAS) to 2 sexual-role questionnaires like "University is more important for a boy than for a girl", Uncertainty Avoidance values (UAI) to 3 questionnaires about confidence(Parliament, The Political parties and Justice System), Long-Term Oriented values(LTO) to 4 questionnaires including "How proud of nationality" and Indulgence versus Restraints values (IVR)to 2 questionnaires including Feeling of Happiness.

일정한 기간동 한 해역에서 연속적으로 어류플랑크톤 재료를 수집하여 분석함 으로써, 그 시기에 존재하는 어류플랑크톤의 사망률을 추정할 수 있다. 이때 대상 어 종의 자치어군은 조사 해역내에 모두 존재하며, 다른 곳으로 이동되지 않았음을 전제 로 한다. 그러나 해양환경은 대단히 역동적이 기 때문에 플랑크톤들은 한 해역에만 계 속해서 머물러 있지 못하고, 시간이 지남에 따라 그 분포범위가 넓어진다. 본 연구는 kim and Bang(1990)에서 제시된 해양확산계내 자치어의 사망을 추정해에 대한 내용을 보충 설명하기 위해서 준비되었다.

There is a rich diversity of galaxy properties and we are starting to understand some of the drivers for differences between galaxies. Much progress has been has been made in the last decade, thanks in large part to massively multiplexed surveys using single fibres, but we still lack a complete picture of how galaxies are built. I will discuss how large-scale integral field surveys can address a number of the outstanding questions in the field, starting with the current SAMI Galaxy Survey, and then looking towards the Hector instrument that will carry out integral field surveys of order 50,000-100,000 galaxies. With SAMI we can start to address how mass and environment influence galaxy structure and history, and I will discuss examples such as the environmental quenching of star formation and the distribution of angular momentum. With larger samples afforded by Hector we can go beyond simply mass and environment, to separate galaxies based on their merger or accretion history, as well as their larger-scale environment.

Purpose - Today's companies concentrate intensively on building consumer value and corporate reputation for continuing growth and advancement in an ever-changing global business management environment. This research intended to study the correlation between consumer value and corporate social responsibility (CSR) activities in building corporate reputation with consumers. Research design, data, and methodology - Online and offline surveys were conducted among male and female adults across Korea. Surveys were conducted for three weeks from August 21, 2018 to September 8, 2018. The samples consisted of 350 offline and 112 online surveys, and a combined total of 462 samples was used for final analysis. Result - Higher consumer value means a greater chance that consumers will select that company's products over those of competitors. For competitive advantage purposes, companies use various consumer management strategies to bolster consumer value and corporate reputation with consumers. Conclusions - Brand assets are subject to ethical responsibility, which is a dimension of corporate social responsibility. Of note, one relevant finding about brand assets (similar to findings in previous research) is the existence of confusion about brand recognition and brand image as perceived by customers.

The rise and fall of social research methods rely on how much a certain method is able to appropriately reflect the change of society. The present research proposes new mobile surveying methods, considering the current and future trends in Korea. In particular, this research focuses on environmental pressure (time constraints, the presence of others and the place) as one of the major factors influencing the effects of survey modes. For example, landline surveys are conducted in the respondent's home, which is a private and fixed space. On the other hand, surveys on mobile phones can be conducted in diverse places with other people around. After sampling 500 landline respondents and 500 mobile phone respondents using a quota method, the same questionnaire was used for both the mobile and landline interviews. The findings are generally consistent with the literature supporting the data quality and comparability of the mixed mode survey. These results are encouraging for researchers designing surveys that feature mobile phone data collection.
