At the moment, construction industry has negative images such as faulty construction, 3D industry and corruption/bribe and they are being projected onto normal people and those engaged in the industry through various news media. Not only does this worsen the lack of skilled manpower by affecting high school students who will be responsible for the construction industry in the future but also makes the future of the industry uncertain by promoting the avoidance of industrial jobs. Therefore, this study suggested basic data for improving the images of construction industry by investigating interest and images of workers in the industry that high school students think as promising construction manpower, and extracting the present negative images through evaluation of associated images.

Inertial Navigation System(INS) can provide the vehicle position and velocity information using inertial sensor outputs without the use of external aids. Unfortunately INS navigation error increases with time due to inertial sensor errors, and therefore it is desirable to combine INS with external aids such as GPS, TACAN, OMEGA, and etc.. In this paper we propose an integration algorithm of commercial GPS/GLONASS and INS where an adaptive filter for signal processing of GPS/GLONASS receiver and the 12th order Kalman filter for aided strapdown INS(SDINS) we employed. Simulation results show that the proposed adaptive filter can effectively remove a randomly occurring abrupt jump due to sudden corruption of the received satellite signal and that the Kalman filter performs satisfactorily.

Apartment housing is a widely-spread type in Korean housing market. Nevertheless, it has caused serious problems such as traditional community corruption, unsafe structure, defects and litigation from noise. Noise, especially in concrete structure for apartment housing, is hardly controlled in proper to prevent sound transmission between upper and lower families with existing system. In foreign countries, there are floating floor system to enhance the noise control performance in multi-family housing. This study is to examine the impact sound insulation performance of floors according to the different P'yong and Layers by field measurement in highrise building.

This letter proposes the use of vowel sound detection for voice activity detection. Vowels have distinctive spectral peaks. These are likely to remain higher than their surroundings even after severe corruption. Therefore, by developing a method of detecting the spectral peaks of vowel sounds in corrupted signals, voice activity can be detected as well even in low signal-to-noise ratio (SNR) conditions. Experimental results indicate that the proposed algorithm performs reliably under various noise and low SNR conditions. This method is suitable for mobile environments where the characteristics of noise may not be known in advance.

In previous study, the linlog(linear log) RASTA(J-RASTA) approach based on PLP was proposed to deal with both the channel effect and the additive noise. The extraction of PLP required generally more steps and computation than the extraction of widely used MFCC. Thus, in this paper, we apply the linlog function to the MFCC for investigating the possibility of simple compensation method that removes both distortion. With the experimental results, the proposed method shows the similar tendency to the linlog RASTA-PLP_ When the J value is set to le-6, the best ERR(Error Reduction Rate) of 33% is obtained. For applying the linlog function to the feature extraction process, the J value plays a very important role in compensating the corruption. Thus, the study for the adaptive J or noise dependent J estimation is further required.

Nevertheless, it has caused serious problems such as traditional community corruption, unsafe structure, defects and litigation from noise. Noise, especially in concrete structure for apartment housing, is hardly controlled in proper to prevent sound transmission between upper and lower families with existing system, In foreign countries, there are floating floor systems to enhance the noise control performance in multi-family housing. Therefore, this study aims to analyze subjective responses on sound characteristics in residential buildings. We analyzed the residential response and the quantities of measured data from environmental noise. The results of this study will be useful to provide guideline to make policy of environmental noise and criteria.

Purpose - Following globalization, Kazakh companies are considered to be among the main economic agents of the country. The influence of Limited Liability Partnerships (LLPs) on Kazakhstan's economic development is becoming increasingly pronounced. Therefore, limitations and backwardness of legislation regarding regulation of corporate governance must be overcome at the earliest. Research design, data, and methodology - We considered the basis for legislation of corporate governance in Kazakhstan, and the corporate governance models that better describe the situation of being in the organization. Results - Earlier studies have identified several problems, including "transparency" of issuers and markets, and the consequent lack of (undeveloped) external control of managers of the former state-owned enterprises; lack of traditional corporate ethics and culture; and corruption, and other criminal aspects of the problem. This article describes several proposals to improve corporate governance in Kazakhstan to solve these problems. Conclusions - Domestic reformers acting without consideration of local features is a common occurrence today. They often ignore that these features are recommended for reputable international organizations, and therefore should be used carefully.

무선 센서 네트워크는 컴퓨팅 용량 및 전력 자원이 매우 제약적인 특징을 가지고 있으며, 이로 인하여 동작시 실패하려는 경향(Error-prone)을 지닌다. 이를 해결하기 위하여 센서 네트워크에 적용 가능한 결함 허용 기법이 요구되며, 현재 노드의 참가(Join), 삭제(Delete), 사망(Death) 및 상태 오염(State Corruption)으로 인하여 발생하는 결함을 처리하기 위하여 노드의 물리적 위치를 기반으로 클러스터를 구성한 후 발생 결함을 지역화하여 처리하는 기법이 제안되었다[1]. 본 논문에서는 결함을 처리하기 위한 기존의 위치 인식 노드 클러스터 시스템에서 발생할 수 있는 헤드 노드의 결함을 효율적으로 처리하기 위한 개선된 기법을 제안하여 전체 센서 네트워크 시스템의 실질적인 가용도(Availability)를 높이고자 하며, 이를 위한 간단한 분석을 수행한 후 효용성을 검증한다.

The mobile tole-cardiology system is the new research area that support an ubiquitous health care based on mobile telecommunication networks. Although there are many researches presenting the modeling concepts of a GSM-based mobile telemedical system, practical application needs to be considered both compression performance and error corruption in the mobile environment. This paper evaluates three wavelet ECG compression algorithms over CDMA networks. The three selected methods are Rajoub using EPE thresholding, Embedded Zerotree Wavelet(EZW) and Wavelet transform Higher Order Statistics Coding(WHOSC) with linear prediction. All methodologies protected more significant information using Forward Error Correction coding and measured not only compression performance in noise-free but also error robustness and delay profile in CDMA environment. In addition, from the field test we analyzed the PRD for movement speed and the features of CDMA 1X. The test results show that Rajoub has low robustness over high error attack and EZW contributes to more efficient exploitation in variable bandwidth and high error. WHOSC has high robustness in overall BER but loses performance about particular abnormal ECG.
