In this study, we investigated the possible use of a new inorganic material as alternative filler in the paper industry. The inorganic material is a mineral composed of calcium sulfate, that is generated when manufacturing phosphate fertilizer. The inorganic material was dehydrated by the thermal treatment to $200^{\circ}C$, $500^{\circ}C$, $700^{\circ}C$, and $900^{\circ}C$ to prepare white filler powders. Their basic properties, including color, particle shape, elements, and average particle size were identified. To determine the effect of new inorganic filler on paper's physical properties and strength, handsheets were prepared from HwBKP, SwBKP, and thermal treated inorganic fillers. Handsheets' ISO brightness, opacity, bulk, breaking length, and stiffness were measured. Results confirmed that thermal treated inorganic filler could be beneficial to the bulk and opacity of paper while maintaining higher level of breaking length and stiffness that is achieved using talc.

창조경제는 새정부 출범과 함께 제시된 새로운 경제발전의 패러다임이다. 정부가 창조경제 정책을 추진한지 3년째를 맞이하고 있으나 창조경제의 규모와 추진 성과에 대한 실감형 분석체계는 부족한 편이다. 이에 본 연구에서는 창조경제 정책 추진의 경제적 파급효과를 정량적으로 추정하기 위한 새로운 방법을 제안한다. 먼저 국내외 창조경제 문헌 검토를 통해 문화 콘텐츠, SW 산업 등 외국에서 정의되었던 창조경제의 범위를 협의의 창조산업군으로 정의하고, 우리 정부에서 제시한 고기술 첨단제조업, 과학기술서비스업 등을 추가적으로 포괄하여 광의의 창조산업군을 정의하였다. 다음으로 각 산업군 별로 창조경제의 핵심 동인 중 하나인 ICT기반 혁신에 따른 투입-산출의 연도별 증감액을 추정하고 산업 연관분석을 통해 창조산업 내 ICT 기반 혁신이 전체 산업에 미치는 경제적 파급효과를 추정하였다. 분석 결과 2013년 이후 전반적인 경기 하락세에서도 광의의 창조산업에서의 ICT기반 혁신이 전 산업의 생산, 부가가치 및 고용유발효과의 상승세를 견인하고 있음을 확인할 수 있었다. 그러나 협의의 창조산업군에서는 ICT기반 혁신의 경제적 파급효과의 증가가 미미한 것을 확인하였다. 본 연구는 크게 두 가지 관점에서 이론적, 정책적 의의가 있다. 첫째로 기존의 창조경제 성과지표가 투입 역량 중심으로 되어 있어 가시적 효과를 산정하기 어려운 상황에서 산업연관분석을 통한 산출 중심의 성과를 추정하는 새로운 방법론적 토대를 제공하였다. 두 번째로 기존의 창조산업 파급효과가 단순히 해당 산업군의 규모 추정에 그쳐 추상적이고 모호하였다면, 본 분석에서는 창조산업의 전체 규모 중에서 ICT기반 혁신활동이 설명하는 파급효과를 구체적으로 산출하여 효과 산정의 타당성과 신뢰성을 높였다는 점이다.

최근 ICT 기반 고부가가치 조선해양 산업 요구의 증가로 조선해양 분야의 소프트웨어 비중과 중요성에 대한 기대가 높아지고 있다. 본 논문에서는 재사용 소프트웨어 컴포넌트 개발을 통해 조선해양 분야 소프트웨어 경쟁력을 향상시키는 것을 목적으로 수행한, 설문조사 기반의 조선해양 소프트웨어 개발 환경 분석 결과를 제시한다. 설문조사는 서로 다른 업체에 종사하는 34명의 조선해양 소프트웨어 개발자들을 대상으로 수행 하였으며, 설문 항목은 소프트웨어 개발 업체의 규모나 개발 제품의 기술 분류와 같이 조사 대상 SW 개발 업체 정보를 파악하기 위한 항목과 소프트웨어 개발이 수행되는 플랫폼, 언어, 배포 형태, 컴포넌트 개발 방해 요인, 개발 프로세스 및 품질관리 도구 사용 여부 등의 소프트웨어 개발과 직접적인 관련이 있는 항목들로 구성하였다. 설문조사 분석 결과에 따르면 개발자들이 개발환경을 선택할 때 가장 큰 영향을 미치는 요소는 이용 가능한 도구의 다양성과 기술지원 여부였으며, 성능, 제품의 가격, 보안이 그 다음 고려사항이었다. 또한 소프트웨어 경쟁력 향상을 위한 한 가지 방법인 재사용 컴포넌트의 개발을 가로막고 있는 주요한 원인은 다양한 플랫폼 지원과 신뢰성 보장의 어려움, 개발 비용과 인력 부족으로 조사되었다. 마지막으로, 개발 프로세스와 품질관리 도구를 전면적으로 사용하여 체계적으로 소프트웨어를 개발하고 있는 개발자의 비율은 전체 조사대상 개발자의 15% 정도에 불과한 것으로 조사되었다. 이러한 사실로부터 현재 조선해양 업체들의 고품질 소프트웨어 개발 능력을 향상시키기 위해서는 해당 업체들에 대한 기술적 제도적 지원이 필요한 상황임을 알 수 있었다.

Recently, improving service quality for customer satisfaction is one of the most important issues and the task for the growth of company. Furthermore, plenty studies are going on progress to develop service quality in IT industry. There have been so many researches of product quality on package software but yet the service quality of package software has been rarely studied before. Thus, the purpose of this study is to formulate a scheme on how to enhance the competitivity of package software company by analyzing the impacts of these two factors on the customer satisfaction, Word-of-Mouth intention and the reuse intention. The study models have been designed and the hypotheses have been made through the examination of the precedent literature about package software product and service quality. A questionnaire survey was performed to collect information, and the unit of analysis was a person who used package software. This study used the statistical technique such as regression analysis. This study may be utilized as basic data for building marketing strategies when package software companies offer service to customers.

The sensory characteristics of a rice processed snack for 6 to 12 month old infants were investigated. The microbiological safety of all samples was also tested. The moisture content of snack of the SW snack was 6.33 significantly higher than in the other snacks (p<0.05). The sensory intensities of RW were highest in glossiness brightness, uniformity, sweet aroma, savory flavor, sweet flavor, chewiness and crispiness. In the; consumer acceptance test, RW showed significantly higher glossiness, uniformity, sweet aroma, savory flavor, sweet flavor, rancid, chewiness, adhesiveness, crispiness and overall acceptance than the other snacks (p<0.05). The aerobic plate counts were negative in all the samples tested. E. coli and pathogenic microorganisms tests were also negative or not detected, showing that all the samples tested were microbiologically safe according to the food code which applies to food manufacturers. Overall, potentially high value products of rice processed snacks for 6 to 12 month old infants were developed and tested They are expected to be utilized and in the competitive and growing infant food industry.

SMBA (Small and Medium Business Administration) and TIPA (Korea Technology and Information Promotion Agency for SMEs) have operated the Business Innovation Platform for SME Informatization based on cloud computing technology with the cooperation of seven industry cooperatives since 2013. This project will evolve into the open market platform where service providers and users voluntarily participate and transact. This research conducts the literature review about the concept of open market and the empirical analysis through survey for the software providers and the future users regarding the future operation methods. The policy about how the open market strategy for the business innovation platform needs to be designed and implemented are organized as the three differentiated government support strategies. The first is to provide free IT services including specialized core operation support S/W which is developed only for the small or home office group of firms which lack minimal informatization capability and budget. The second is to augment IT platform service through incorporating ERP supplier initiated commercial S/W sales window for those firms having medium level informatization capability. This includes to provide IT support for customization and system integration with existing government subsidized S/W. The third is to provide upgrading services of existing S/W functions to facilitate better system utilization. The results provide useful insight for government role to enhance SME competitiveness using IT.

With the increasing severity of the shortage of highly-skilled IT personnel, more and more attention is being paid to the professional career path and systematic career management of IT employees. Although some studies have been conducted to describe the current status of IT personnel, limited attempts have been made to analyze the career paths or career patterns of IT professionals from a longitudinal perspective. In this context, this study explored the job career patterns of IT professionals in Korea and examined their relationship with subjective and objective career success. To identify job career patterns over time, detailed information about jobs and positions were used and an optimal matching analysis (OMA) was conducted to calculate the dissimilarity matrix between employees' career sequences, while a cluster analysis was used to categorize the meaningful groups based on this dissimilarity data. This analysis revealed that career patterns among Korean IT personnel are more varied than previously thought. These career types have a significant relationship with individual profiles, such as age, education, industry and company size, and account for significant variations in the three main career success variables, i.e. quality of life, assessment of software quality, and wage level. It is expected that the findings of this study will contribute to refining the Korean career path so as to retain IT personnel, and raise the need to improve the low quality of life and poor SW work environment of IT personnel.
