Maturation and spawning of the jack mackerel, Trachurus japonicus was investigated based on the samples captured in the coastal waters around Jeju Island from January 2007 to December 2008. Gonadosomatic index began to increase in March, and reached a maximum between April to June. After spawning it began to decrease from August. Reproductive season was estimated to March-July, with peak in April. Fecundity was proportional to the size of the female, with the clutch size varying from 33,493 eggs in the smallest female(FL=27.0cm) to 627,061 eggs in the largest(FL=40.6cm). Size at 50% sexual maturity(FL50), determined from mature females, was 26.6cm FL. Annual reproductive cycles of this species could be divided into six successive stages; immature stage(September-December), nucleolus stage(January-February), yolk vesicle stage(February-March), vitellogenic stage(March-April), ripe stage(April-July) and spent stage(July-September).

This study suggests a model for building governance system to develop and utilize human resources in Chungnam province. In particular, In the regional level of balanced development of human resources, the study tries to investigate alternatives to utilize regional human resources development by building and using a network between related organizations through their partnership and cooperative relations. This survey was conducted to 250 of personnel and experts who were in charge of human resources in diverse chungnam institutions through mail or e-mail from December in 2008 to February in 2009. As a result of the survey, the study shows that basic groundwork for the regional human resources development is poor in terms of forming the system and its plans, and the ties and cooperation between related organization, Therefore this study shows that in order to overcome the current situation and build the governance appropriate to Chungnam area, we need to consider different approaches for each regional organization stage by stage regarding the maturity in the governance.

As W-CDMA R5(HSDPA) service became recently commercialized in Korea, there is increasing demand for new pricing methodology for the 3G mobile interconnection at the earliest possible time. However, it is hard to find any case of systematic study on it. In this paper, a synthetic investigation into the three aspects of new mobile telecommunication service - technology, market, and regulation - is conducted to verify the validity of new interconnection pricing methodology. As the findings of this research indicate, given the several technological limits of 3G, speed of mobile telecommunication industry evolution, the problem of verifying ex-ante regulations' validity, and the cases of some foreign countries, it is suggested that immediate revision of interconnection policy is not sensible and that the revision is more desirable to be postponed until the maturity of the 3G market or the adoption of All-IP network.

The Internet of Things(IoT) is to build a hyper-connected society through interconnection, and on this basis, to improve the quality of life and productivity, including solving social problems, and to become the next growth engine for the nation. The open common eco-system pursued by the IoT can start with the under- standing of the word 'open'. The IoT can achieve the expected effect of lowering the barriers to entry of technology development, and in these changes, OSSW and OSHW play a very important role in accelerating IoT eco-system maturity and breaking the boundaries between industries to promote convergence. Recently, it has developed into an intelligent IoT that combines artificial intelligence (AI) with the connectivity of the IoT. Here, I will analyze the direction of development of the IoT through understanding and analysis of open source.

지난 몇 년간 HCI 분야에서 사용자 경험 (User Experience)이라는 용어는 전통적 의미의 사용성부터 심미적, 유희적, 감성적 그리고 기술 사용을 포함하는 사용의 전반적인 경험을 일컫게 되었다. 기술 성숙과 더불어 제품의 빈번한 상호작용으로 인해, 사용자는 제품의 도구적 의미의 유용성과 사용성에 대한 기대 충족 뿐만 아니라, 심미성, 감성 등 사용자의 내재적 가치까지 만족시켜주길 원한다. 본 연구는 사용자의 실용적인 목적 뿐만 아니라, 내재적 가치까지도 고려한 전체 사용자 경험 연구를 위해, 제품의 '도구적 요구 관점' 과 '비도구적 요구 관점' 을 함께 고려하고자 한다. 비인간 대상을 사람으로 간주하는 의인화 (Anthropomorphism) 연구에서는 대상을 도구적임과 동시에 비도구적으로 대하려는 현상을 보여준다. 이런 의인화 연구들을 착안하여, 본 연구는 의인화의 의의와 도출 과정을 살펴보고 HCI 분야에서 왜 의인화 관점의 연구가 중요한지, 사용자들은 언제 어떻게 사용하는 제품을 의인화하려는지 다른 분야의 의인화와 비교 설명하려 한다. [연구 1]에서는 2 개국 (독일, 인도) 에서 4 개의 디지털 기기 (핸드폰, MP3 플레이어, TV, 냉장고) 사용자를 대상으로 Contextual Interview 를 실시 후, 분석하여 국가별 디지털 기기 별 주요 의인화 요소들을 도출하였다. [연구 2]에서는 의인화 관점의 분석 결과가 문화적 차이에 따라 어떤 영향을 받는지를 검증하기 위해 [연구 1]의 통일 2 개국에 문화적 성향 측정을 위한 설문을 실시하였다. [연구 1]과 [연구 2]의 결과를 통해 HCI 분야에서의 의인화 관점 연구의 의의와 프레임웍을 설명하고, 문화적 차이를 반영한 제품의 의인화 가이드라인을 제시하고자 한다.

Science cultures in the dimension of social interaction must be correlated with science cultures or science literacy in the dimension of psychological interaction. In order to develop a mature science culture, it must be assumed 1) that a science culture in a society ran be evaluated and 2) that we have to set up the criteria for evaluating it. This paper, based on the assumptions, makes an attempt to analyze the concept of science literacy underlying the PISA (Programme for International Student Assessment) conducted by OECD. The analyses are driven by the questions such as 'which philosophical backgrounds are absorbed into the concept of PISA' science literacy?' and 'What suggestions can be found with respect to the goal of enhancing the science culture?' In conclusion, the science literacy in PISA reflects the elements proposed by logical empiricism, naturalized philosophy of science, and social constructivism, which are being incorporated by the 'collaboration research program' conducted by the newly-emerging interdisciplinary field of 'science of science.' Finally, some further suggestions are added to the analyses to pursue more positive directions to induce mature science cultures in our society.

The tooth selectivity of the dredge for catching venus clam (Gomphina melanaegis) was described in which the teeth penetrated the bottom and lifted the shell into the bag. Some factors affecting the selection action of the teeth of the dredge were analyzed related to shell length and shell height. The retention probability of venus clam not sifting through the gaps between the teeth was calculated for various shell lengths and was fitted to two parameter logistic selection curve. The formula obtained is as follows: $P= \frac{1}{1+exp[8.24](\frac{d}{L_1}-0.649)}$, where d is distance between teeth and $L_1$ is a shell length. For biological minimum size(25mm) of venus clam to be catchability 50% the distance between teeth was estimated 16.2mm from the logistic curve. Therefore it is desirable to extend that current spacing between teeth from 12mm to 16mm for the venus clam dredge. That space increasing enables fuel oil of vessel to drag a dredge to be reduced and also man power to sift through sifter smaller venus clams on boards to be reduced.

막대한 예산을 투입하여 추진하고 있는 지자체 GIS사업은 기술의 발전에 비해 제도, 교육, 사용자의 마인드, 유지관리 활동, 향후 사업 구상 등에서 상대적인 빈곤을 경험하고 있는 것이 사실이다. 이렇듯 신기술이 도입됨에 따라 다양한 제반 여건들이 동반적으로 성숙하지 못함으로 인해 발생하는 현상을 과도기적 현상1)으로 진단하고 있다. 이미 다양한 분야에서 GIS를 도입한 지자체에서는 이러한 과도기적 현상을 극복하기 위해 상당한 어려움을 겪고 있으며, 새롭게 GIS를 도입하고자 하는 지자체에서도 타 지자체에서 모니터링을 통해 간접적으로 과도기적 현상을 경험함으로 인해 효과적인 사업 추진을 구상하는데 상당한 어려움을 겪고 있는 것이 현실이다. 또한 지자체의 경우 중앙정부에서 추진하고 있는 다양한 사업에 영향을 받을 수밖에 없고, 현재의 GIS 사업의 추세가 단순한 공간정보 중심의 사업이 아닌 다양한 속성정보와의 연계를 모색하고 있다는 점에서 지자체 GIS정보화의 방향은 예전과는 사뭇 다른 양상을 간파해 야 하는 현실에 놓여 있다. 이와 같은 지자체 GIS의 과도기적 현상을 극복하기 위해서는 정보기술의 빠른 변화속도와 외부환경의 극심한 환경변화의 상황에서 ‘보이는 것과 보이지 않는 것’의 관계를 진단하고, 변화에 대한 예측과 대비, 중요한 일과 급한 일을 구분한 총체적인 밑그림의 마련과 실행계획의 수립이 우선시 되어야 한다. 지자체 GIS의 문제 해결의 노력이 단숨에 바로 해결되는 것이 아니고, 또한 현재 추진된 사업을 기반으로 중복투자의 방지와 시너지 효과 극대화를 위한 투자의 노력이 장기간의 시간적 개념속에서 진행되어야 한다는 점에서 이를 이끌어줄 가이드가 필요한 것이다. 이러한 총체적인 지자체 GIS의 계획마련을 위해 건설교통부에서는 ‘국가지리정보구축 및 활용등에 관한 법률’상에 계획 수립의 항목을 명문화하고, 나아가 GIS정보화 전략계획 수립에 관한 지침작성을 위한 노력을 진행 중에 있다. 이러한 일련의 현실을 감안하여 지자체 GIS정보화 전략계획 수립을 체계적이고 실질적으로 수립할 수 있는 ‘지자체 GIS정보화 전략계획 수립모델’은 반드시 선행되어야 할 사항임에 분명하다. 지자체 GIS정보화 전략계획 수립 모델은 지자체 GIS정보화 전략계획 수립의 효과로 하고 있으며, 형식적 측면에서는 GIS특성을 반영한 전략계획 수립의 방법론적 측면을 중심으로 구성된다. 이러한 과정을 거처 실제 지자체 GIS정보화 전략계획을 수립하는데 필요한 9단계를 설정하고 각각의 단계에 대한 중심활동을 바탕으로 지자체에서 실제 전략계획 수립에 필요한 지침을 작성하는 것으로 구성되어 있다.
