국내광업은 '90년대 이후 석탄산업합리화조치와 국제금속광물시장 가격안정화로 그동안 광업을 주도한 석탄산업과 금속광업은 급격히 위축되는 한편, 산업원료의 수요증가 추세에 힘입어 비금속광물 개발은 비교적 활발한 상태이다. 이와 같이 국내 광업의 주된 영역이 석탄광과 금속광에서 비금속광 중심으로 개편되고 있으나, 현재 가행중인 비금속광은 고품위광체 확보 미흡, 고부가가치 기술낙후 등으로 고가의 주요 산업원료는 주로 수입에 의존하고 있는 실정이다. 따라서 국내광업으로서는 비금속광 중심의 단순한 원광석 생산$\cdot$판매체계를 고부가 산업으로 전환시키기 위한 전략적인 방안이 필요한 시기이다. 본 발표문은 이러한 국내광업의 향후 발전방향을 모색하기 위하여 국내 광업이 국가 경제에서 차지하는 영역을 중심으로 $\ulcorner$광업동향$\lrcorner$ $\ulcorner$광업의 국내$\cdot$외 환경분석$\lrcorner$ $\ulcorner$광업의 경제활동 현황$\lrcorner$ $\ulcorner$광업의 경제적 위치와 역할$\lrcorner$로 분류하여 자료분석을 실시하였으며, 분석한 자료를 토대로 국내광업의 중요성과 당면과제를 도출하고 이에 따른 광업의 새로운 역할을 제시하고자 하였다. 국내광업은 각종 지표에서 나타난 바와 같이 여러 가지 구조적인 문제점으로 인해 개발에 어려움을 겪고 있지만 각종 산업원료의 중간재 공급원으로서의 전통적인 역할을 충실히 담당하고 있는 것으로 분석되었다. 그러나 과학기술의 급격한 발달, 소비패턴의 변화, 생활환경과 삶의 질을 중시하는 새로운 가치관의 확산 등으로 광업의 역할도 새로운 변화의 전기를 맞이하고 있음을 볼 수 있다. 국내광업이 21C 급변하는 산업환경에 적응하여 생존하기 위해서는 각종 첨단산업에서 요구하는 소량 다품종의 원료광물을 적기에 공급 할 수 있는 전문화된 기술력을 하루속히 확보해야 하며, 이를 위해 고품위의 원료광물 확보를 위한 탐사 및 개발을 적극 추진하고 가공기술의 선진화를 위해 선진국과의 기술제휴 등 자원산업 글로벌화 정책이 절실히 요구되고 있음을 알 수 있다. 또한 삶의 질을 향상시키려는 현대인의 가치관에 부합하기 위해서는 각종 소비제품의 원료를 제공하는 광업의 본래 목적 이외에도 자연환경 훼손을 최소화하며 개발 할 수밖에 없는 구조적인 어려움에 직면할 수밖에 없다. 이처럼 국내광업이 안고 있는 여러 가지 난제들을 극복하기 위해서는 업계와 정부가 합심하여 국내광업 육성의 중요성을 재인식하고 새로운 마음가짐으로 관련 정책을 수립 일관성 있게 추진해 나가야 할 것으로 보인다.

In this paper, we proposed the standard test specification for safety and function of hiking stick for the elderly. We have concluded nine factors representing specification of hiking stick through analysis of hiking patents and research papers, products survey of business market, case studies for damaged hiking stick and expert surveys. To test the factors, we designed three different kinds of apparatus to examine twist resistance, stick and tip durability and stick straightness. The sample of hiking sticks purchased from market based on Naver sales ranking top to fifteenth. As a result, we concluded six-standard test specification based on eccentric load, adjustable parts load, hand strap load, basket load, tip load and pull load of hiking stick.

21세기를 맞이하는 기업은 세계화와 국제화, 정보의 다양화 및 분산화, 제품수명주기의 단축과 수익률의 감소, 고품질의 제품, 지식산업의 등장, 고객 욕구의 증대 등 다양한 내 ${\cdot}$ 외적 환경변화에 대응해야 하고 경쟁우위를 확보하기 위해 끊임없이 기업의 변화능력을 확보해야 한다. 기업은 제품을 생산하여 판매하는 기업의 시스템 전체가 경쟁력을 갖추어 총체적 우위를 확보하고 고객의 기호와 감성에 호소하는 제품을 만들 수 있도록 다양한 정보를 제공하는 시스템을 필요로 하게 되었다. 즉, 시간과 서비스에 뒤진 고객지원체계는 기업의 성장에 절대적인 마이너스 요인이므로 고객 정보의 효율적 관리, 고객 요구에 대한 신속한 대응, 정기적 고객만족도 조사 등 고객이 원하는 것을 재빠르게 얻어낼 수 있는 고객 친밀형 정보시스템의 확립이 요구되는 것이다. 이를 해결해 줄 수 있는 새로운 경영정보시스템이 바로 WebERP인 것이다. WebERP는 기업의 원활한 자재, 구매활동을 위해 제안된 MRP에서 시작되었으며, 생산관리의 개념을 포함하고 있는 MRPII로 확대되었다가 다시 인사나 회계, 재무 등 조직이나 기업의 전업무영역을 수용하는 종합경영정보시스템으로 발전된 것이다. 현재는 전자상거래와 관련하여 WebERP의 필요성이 부각되었고, 모기업과 협력사간의 구매발주 및 납품관리를 확대시켜 소모성자재(MRO: Maintenance, Repair & Operation) 및 기타 공동구매서비스와 유사업종간의 그룹을 형성하여 ASP(Application Service Provider)의 공동 환경을 이용한 WebERP 환경을 이용한 WebERP활용이 현시점으로 적실히 필요한 것이다. 이는 중소기업들의 공동 협업체제를 도모하여 외세를 대비하는 응집력을 확고히 함으로써 집단체제의 e마켓플레이스 확립과 더불어 국제경쟁을 대비한 방안으로서 집단 공동의 웹환경 인프라가 필요한 것이다. 이러한 배경에서 ASP환경을 이용한 WebERP활용방안과 시스템 구축전략을 경남지역의 기계산업정보화사업단이 추진하는 일반기계, 전기기계, 금속기계, 수송기계, 정밀기계의 5개 업종을 4,877개 기업 대상으로 추진하고 있으며, 그 중 WebERP의 모델로서 2003년도까지 50개 기업을 선정하고, 이는 5개 업종 골고루 선정하여 적용과 표준화 모델로 전개해 나가는 것을 정리한 것이다.

As game item trading becomes more popular with the rapid growth of online game market, the market for trading game items by cash has increased up to KRW 1.6 trillion. Thanks to this active market, it has been easy to turn these items and game money into real money. As a result, some malicious users have often attempted to steal other players' rare and valuable game items by using their account. Therefore, this study proposes a detection model through analysis on these account thieves' behavior in the Massive Multiuser Online Role Playing Game(MMORPG). In case of online game identity theft, the thieves engage in economic activities only with a goal of stealing game items and game money. In this pattern are found particular sequences such as item production, item sales and acquisition of game money. Based on this pattern, this study proposes a detection model. This detection model-based classification revealed 86 percent of accuracy. In addition, trading patterns when online game identity was stolen were analyzed in this study.

This paper proposes a differential pricing model for industrial land based on locational characteristics, using Support Vector Regression (SVR) as a land pricing methodology. The initial selling price of industrial land is set based on the total cost of site development that comprises the land acquisition cost and tax, land development expense, infrastructure installation cost, labor cost, migration expense, selling and administrative expense, capital cost, and so on. However, the current industrial land pricing method unreasonably applies the same price per square meter to all parcels within an industrial complex without considering differences in price depending on the location of each parcel. Therefore, this paper proposes an empirical land pricing model to solve this irrationality and verifies its validity and applicability.

In this study, we achieve an increase in sales of dairy companies through innovation in the distribution process of developing core competencies through product differentiation in the domestic dairy companies, creating new consumption pioneered new markets. First of all, improving the quality of milk in the premium milk market can be able to expect the activation of consumption and through promotion activities by the Korean wave can lead to create new consumption pioneered the market diversification at the same time export varieties of white milk and jersey species take advantage of a variety of milk in addition to drink beauty and cooking areas while lowering manufacturing costs through the introduction of the cheese will increase the revenue of the dairy companies and dairy consumption expected to activate at the same time. It is necessary to change cultivars in order to think about nutritional value and flavor, and further environment, and high quality premium milk will become a new trend in the future. Furthermore, promoting the benefits of milk consumption would contribute in raising the milk demand that is negatively correlated with increasing age.

It is only 9 to 10 years since the use of internet became commercial. But electronic commerce is now a familiar form of commercial transaction. Though the ratio of electronic commerce compared to total commercial transaction is still low, it is certain that electronic commerce will be the major form of transactions in the future. In July 1, 1997, United States made a public "A Framework for Global Electronic Commerce" to set up Internet to be a duty free zone and declared to play the trigger role in getting the international discussion of "A Framework for Global Electronic Commerce". In July 8, 1997, EU also adopted "Bonn Declaration"-minimizing government regulations and imposing no new tax on electronic commerce. Focusing the international trend, we need to develop the tax policy that is suitable for our country situation as soon as we can. To be able to do that, we must make an endless effort like selecting professionals, making new administrative part and supporting the research.
