In this paper, the interferometric coherence was estimated and the amplitude intensity was extracted using the repeat-pass interferometric data, acquired by European Remote Sensing Satellite 1 and 2. Then discrimination and classification of surface land types in Zhangjiakou test site, Hebei Province were carried out based on the coherence estimation and the intensity extraction. Seven types of land were discriminated and classified, including in two different types of meadows, woodland, dry land, grassland, steppe and water body. The backscatter and coherence characteristics of these land types on the multi-temporal images were analyzed, and the change of surface features with time series was also discussed.

The purpose of this study is to analyze the perceptions of obesity among appearance-conscious women in their 20s. It is intended to provide data necessary to produce garments for obese body types by identifying adult women's subjective assessments of obese body types and characteristics. The data were analyzed using Q Methodology in the QUANL program for PC. Type 1 was recognized as uniformly fat in the abdomen, with almost the same width and thickness. Type 2 was perceived to have more fat in the upper body and back, broad shoulders, and an inverted body type. Type 3 was perceived as having a fat lower half of the body, hips wider than the chest, and large thighs. Type 4 was identified as having few curves and fat concentrated in the abdomen. Further research of other age groups and regions is needed to ascertain the difference between perceived and actual body types.

Purpose: This study aimed to provide fundamental data for the development of a human management strategy depending on the followership type in 119 EMTs. Methods: The subjects were thirty eight 119 EMTs working out of hospital in Y, D, S, G city. Data were collected from June 25 to August 10, 2017. The Q sample was selected as 40 statements in total and analyzed using the PC QUANL program. Results: As a result of the study, three followership types explained 67.59% of all the variables. Three different types were identified from the examination. The types were labeled as 'Responsible helper type', 'Quick response type', and 'Enterprising self-development type'. Conclusion: For each type, a leader and follower should develop a team management strategy for 119 EMTs to provide high-quality emergency medical services.

Purpose: The purpose of this study was to provide basic data for developing strategic programs based on 119 emergency medical technicians leadership perception types. Methods: The subjects were thirty six 119 emergency medical technicians working for out-of hospital in Jeollanam-Do, Korea. Data were collected from July 20, 2017 to October 30, 2017. Q sample of 40 statements and P sample of 36 persons using PC QUANL software. Results: Three types of leadership styles were identified from the explanation (71.5% of the variables). The relationship oriented progressive type (the most common), the performance and value oriented type (the second most common), and the experience oriented filed participation type (the third most common). Conclusion: The fire department will need to develop and implemented leadership improvement programs based on the leadership types in order to meet the organization's goals.

The vacant houses commonly observed in urban aging are considered to be representative signs of urban decline. Vacant houses are themselves vulnerable to security, and in particular, they are exposed to disasters due to poor management, which can accelerate the decline of the area. This study is to classify the area and analyze the causes and characteristics of the occurrence of vacant houses by type based on the data through the survey on the vacant houses in Incheon. This research analyze vacant house data survey so to characterized and categorized types of vacant houses. The criteria of vacant houses analysis are population density, population growth, aging extent. In conclusion there are four types of region in Incheon area according to housing types, hazard classes, building age and building areas. Type A is inner city, type B is mixed, type C is expandable and type D is unsular types.

The purpose of this study is to analyze empirically the influences of different types of household income and asset in the consumption expenditures of homeowners and lessees with deposit. The data used in this study were the 1996 Korea Household Panel Study. 1,512 households data were selected for the final analysis. The statistical methods adopted for data analysis were frequency, percentage, one-way ANOVA, crosstabs, multiple regression analysis, and chow-test. The results are as follows: (1) There were the differences between three groups in the expenditure levels of each consumption category and the shares of each consumption category of total expenditures. (2) The change of labor income influenced more significantly consumption expenditures of homeowners and lessees with deposit, compared to changes of different types of household income. Also homeowners and lessees with deposit changed their consumption expenditures in different ways to changes of various types of household income. (3) Homeowners increased more significantly their consumption expenditures to increase of net asset than lessees with deposit.

In this paper production and perception data were examined to discover what acoustic features are used in distinguishing wh-questions and yes/no-questions. Production data show that the two question types are distinguished by different accentual phrasing, pitch ranges in wh-phrases, and initial lenis stop voicing of the first syllable in verb phrases. Perception data by synthetic intonation show that the two question types are distinguished by the width of pitch ranges between the first and the second syllable in wh-phrases. Initial lenis stop voicing of the first syllable in verb phrases produces a strong effect on the perceptual discrimination of the two question types.

This paper proposes an efficient and accurate power estimation method for Application Specific Instruction set Processors (ASIPs). Proposed method takes advantage of the data types of variables in application program to be executed on the ASIP. According to the experimental results, the efficiency of proposed method was more than 1000 times as high as that of conventional RTL based power estimation method, and the estimation error was within 10% compared to a conventional gate-level accurate power estimation method

The purpose of this article is to examine types and construction method of multimedia materials for the Korean language education, finally in order to construct digital library on Nuri-Sejonghakdang. Firstly, this article reviews some major concepts such as teaching material, multimedia, learning object, meta-data, reusability, etc. Secondly, various multimedia materials are divided into three types(namely, example material, explanation material, training and evaluating material) according to their characteristics as a learning objects. And then, this article tries to propose the classification-search system and meta-data elements for effective search and use of multimedia materials. Finally, this article is concluded by presenting the long-term plan of digital library construction on Nuri-Sejonghakdang and some follow-up task of this study.

The widespread introduction of unmanned aircrafts has led to the understanding of the need to organize a common information space for manned and unmanned aircrafts, which is reflected in the Russian Unmanned aircraft system Traffic Management (RUTM) project. The present article deals with the issues of spatial information database (DB) organization, which is the core of RUTM and provides storage of various data types (spatial, aeronautical, topographical, meteorological, vector, etc.) required for flight safety management. Based on the analysis of functional capabilities and types of work which it needs to ensure, the architecture of spatial information DB, including the base of source information, base of display settings, base of vector objects, base of tile packages and also a number of special software packages was proposed. The issues of organization of these DB, types and formats of data and ways of their display are considered in detail. Based on the analysis it was concluded that the optimal construction of the spatial DB for RUTM system requires a combination of different model variants and ways of organizing data structures.
