The information security industry market is sluggish despite high expectation for its growth, and thus policies are required to define the causes and to address these issues. The policy formulation requires various historical market and human resource data for analyzing the industry, which cannot be guaranteed secured. This study executed face-to-face in-depth interviews with the frontline businesses in order to gather live opinions and to analyze industry's value chain, problems, and difficulties with a view to defining policy tasks for the development of the industry. The findings of the study revealed the current technical level of the information security industry, the frontline difficulty, and industrial ecosystem status. Based on these findings, the industry revitalization policy was devised and proposed. Objectives of the policy included the fostering of capacity to conceptualize, plan, and design industrial strategies based on the analysis of the industry's value chain and ecosystem, the expansion of the industry's value-added through the enhanced securing and management of the Intellectual Property Rights (IPR), and the nurturing of the security Human Resources (HR) in line with the industrial demand.

The present study highlights the conflict management levels in Indian manufacturing and Information Technology (IT) sectors. Nearly 110 samples from different organizations of manufacturing and IT have been collected using convenient sampling technique. Standardised scale on Organisational Conflict developed by Dhar U. and Dhar S. [2003] has been used which consists of twenty items on a four point scale. The study has shown that miscommunication at organizational level has been a reason for conflict in manufacturing organizations whereas intrinsic motivation at organizational as well as individual level has been found a reason for conflict in IT sector. The study bears implications for HR managers to develop policies and conflict management strategies so as to deal with the situations constructively at a particular level of conflict.

Transparent conductive oxide (TCO) are necessary as front electrode or anti-reflecting coating for increasing efficiency of LED and Photodiode. In this paper, aluminum-doped Zinc oxide films(AZO) were prepared by RF magnetron sputtering on Si substrate at room temperature with application of substrate bias from -60 to 60 V. Then annealed at temperature of 200, 300 and $400^{\circ}C$ for 1hr in $H_2$ ambient. Structural and electrical property of AZO thin films were investigated.

The persons who realize e-Business should have capabilities of understanding in both Information Technology and business processes. It is expected that current education policies and systems could not meet needs of e-Business Human Resources in Korea, In this paper. we define and categorize HR for e-Business. Using this, we present policies for a development of e-Business human resources. after conducting intensive field survey, Also we develop a program for e-Business education. In order to develop that, we research previous studies on skills and knowledge requirements of human resources and e-Business education program.

This paper presents the characteristics of Ta-N thin-film strain gauges as high-temperature strain gauges, which were deposited on Si substrate by DC reactive magnetron sputtering in an argon-nitrogen atmosphere(Ar-($4{\sim}16%$)$N_2$). These films were annealed for 1 hour in $2{\times}10^{-6}$ Torr vacuum furnace range $500{\sim}1000^{\circ}C$. The optimized conditions of Ta-N thin-film strain gauges were annealing condition($900^{\circ}C$, 1 hr.) in 8% $N_2$ gas flow ratio deposition atmosphere. Under optimum conditions, the Ta-N thin-films for strain gauges is obtained a high resistivity, ${\rho}$=768.93 ${\mu}{\Omega}cm$, a low temperature coefficient of resistance, TCR = -84 ppm/$^{\circ}C$ and a high temporal stability with a good longitudinal gauge factor, GF = 4.12.

In this paper, we design a small low power single channel ECG(Electrocardiogram) system of Chest Belt type with fiber-type electrodes to measure emotional state change of game addict. HRV(Heart Rate Variability) is analyzed through heart rate signal measurement and the psychological stress state is judged by using it. And it verifies its effectiveness through prototype. First, we design HR measurement module through low power MCU(Micro Controller Unit) and implement prototype level measurement system. The results showed that the difference between the addiction group and the general group was confirmed and that the system was effective. The result of this study can be used for health management such as reduction of stress of the user through music and breathing that lowers the stress by detecting the stress state of the general person or the chronic ill person.

In this research, we presented an effective clustering method based on ICA for the analysis of huge Raman hyperspectral dental data. The hyperspectral dataset captured by HR800 micro Raman spectrometer at UMKC-CRISP(University of Missouri-Kansas City Center for Research on Interfacial Structure and Properties), has 569 local points. Each point has 1,005 hyperspectal dentin data. We compared the clustering effectiveness and the clustering time for the case of using all dataset directly and the cases of using the scores after PCA and ICA. As the result of experiment, the cases of using the scores after PCA and ICA showed, not only more detailed internal dentin information in the aspect of medical analysis, but also about 7~19 times much shorter processing times for clustering. ICA based approach also presented better performance than that of PCA, in terms of the detailed internal information of dentin and the clustering time. Therefore, we could confirm the effectiveness of ICA for the analysis of Raman hyperspectral dental data.

본 연구에서는 광섬유 자이로(Fiber Optic Gyro)의 광학부 간섭계를 모사하고자 한다. 디지털 신호처리를 이용하여 광섬유 고리의 응답특성을 모사한다. 디지털 신호의 1bit 분해능으로 0.1deg/hr의 성능을 내는 광섬유 자이로를 모사하기엔 부족하다. 본 연구에서는 Random Noise를 활용하여 분해능을 높임으로써 광섬유 고리의 성능을 정확히 모사하고자 한다. 입력 레이트에 Random Noise를 실어줌으로써 1bit 분해능의 성능을 높일 수 있다. 1bit 사이의 값들이 랜덤노이즈로 인해 1bit 더해지거나 빼짐으로써 정확한 값을 갖을 수 있다.

Recently, competition in the interior remodeling business is fierce. However, the interior remodeling business is basically B2B, and in this business, sales are basically dictated by the capabilities of salespeople. Therefore, in this study, we intend to develop a model for the core competency of salespeople in the interior remodeling business. To this end, based on the research on the existing competency and competency modeling, the competency model of the salesperson was derived using Dubois' overlay method. A total of 12 core competencies could be defined through the first and second modeling. The subject of this study was focused on LG Hausys, the most representative interior remodeling company in Korea. Based on the core competencies developed in this way, overall sales competencies can be raised through the development of a training course to enhance the sales competencies of salespeople, and a more efficient and objective HR.
