산업화, 도시화는 획일화, 규격화시키는 부작용을 낳았다. 근대화 이후 각 지역은 그 고유의 개성을 상실한 채 성장을 거듭하였다. 그러나 국제화, 지방화라는 시대적 상황속에서 그 지역의 특성을 기반으로 하는 다양한 경제, 문화활동은 지역의 정체성 확립과 이를 기반으로한 지역발전의 출발점이 된다는 인식이 확산되면서 지역의 특성에 대한 새로운 발견과 디자인을 통한 적극적인 개발의 결과들이 많이 나타나고 있다. 지역의 문화를 중심으로한 문화산업의 발굴과 개발은 굴뚝없는 산업으로서 그 중요성과 경제적인 가치를 고려할 때 시급히 정립되어야 할 분야이다. 또한 디자인이 기존의 상황을 전혀 새롭고 창의적인 고부가의 가치로 전화시키는 중요한 수단이라는 인식의 확산은 지역특성화에서 디자인의 역할을 새롭게 인식하게 하고 있다. 지역의 특성을 규정하는 요소에는 도시이미지 형성작업, 경관 디자인, 문화산업, 지역개발등의 분야로 분류할 수 있다. 본 연구에서는 울산광역시의 특성화를 위한 다양한 디자인적 접근 방안중 울산만의 개성있는 지역문화와 자연환경을 배경으로한 테마공원 조성안을 중심으로 지역특성의 디자인적 접근 방안을 모색하고자 한다.

최근 들어, 게임의 부정적 인식에서 벗어나 기능성이라는 목적을 추가한 기능성게임에 대한 관심이 고조되고 있다. 특히, 교육용기능성게임은 재미와 교육의 목적을 동시에 만족시켜줄 뿐만 아니라, 디지털교과서보급과 함께 새로운 교육방법으로 등장하고 있으며 이를 활용한 연구가 활발히 진행되고 있다. 기능성 게임이 게임이라는 부정적 인식에서 벗어나 학습을 보다 즐겁고 자기 주도적 학습을 위하여 다양한 교육용 기능성게임 활성화 정책을 펼치고 있다. 그중에서도 대표적으로 사람들의 기능성게임에 대한 인식을 전환시키며 활성화시키기 위한 기능성게임대회가 펼쳐지고 있다. 하지만 이러한 기능성게임대회 운영전략에도 불구하고 다양한 문제점이 도출되고 있으며, 게임대회의 주된 목적인 저변확대가 잘 이루어지지 않는 실정이다. 따라서 본 연구에서는 교육용 기능성게임 및 게임 대회를 분석하고 효과적인 게임대회운영 전략을 제시하고자 한다.

In the present study, the removal of Pb (II) ions on oxidized activated carbons (ACs) was investigated. ACs were derived from activation of indigenous cotton stalks waste with potassium hydroxide (KOH) in two-stage process. The KOH-ACs were subjected to liquid-phase oxidation with hot $HNO_3$ and one untreated sample was included for comparison. The obtained carbons were characterized by Fourier transform infrared (FTIR), slurry pH and $N_2$-adsorption at 77 K, respectively. Adsorption capacity of Pb (II) ions on the resultant carbons was determined by batch equilibrium experiments. The experimental results indicated that the oxidation with nitric acid was associated with a significant increase in mass of yield as well as a remarkable reduction in internal porosity as compared to the untreated carbon. The AC-800N revealed higher adsorption capacity than that of AC-800, although the former sample exhibited low surface area and micropore volume. It was observed that the adsorption capacity enhancement attributed to pore widening, the generation of oxygen functional groups and potassium containing compounds leading to cation-exchange on the carbon surface. These results show that the oxidized carbons represented prospective adsorbents for enhancing the removal of heavy metals from wastewater.

These days, we face of the flood of books published, and data day by day. But there are some trouble to serve the knowlodge and date to the users efficently with a single library. Thats why we think about the way of the cooporation and the connection in modern library for the method of widening the service. As the result of the issue, the establishment for the relation of each library is needed to be done, and the composition of the public library network in same area and limit are also needed. Establishing the library network, the civil life will be much influenced by the service of a library. With the existing ways, library cant arrange data efficently by them selves, and the users are limited. But the library network collect the data with alloting the work to each portion, so it can be possible to gather the specipic data, and the cost caused by needless and overlapped data can be decreased remarkably. Furthermore, the location of the library can be closer than the existing one due to the less cost to maintain the library. As I explained, the convenience of using the library can make an effect on more people to use a library than before.

This study deals with the traffic accident of truck at circular intersection. The purpose of this study is to develop the truck accident models based on type of accident and conflict. In pursuing the above, the study gives particular attentions to selecting the appropriate models among Poisson and Negative binomial models using statistical program LIMDEP 8.0. The traffic accident data from 2007 to 2014 are collected from TAAS data set of Road Traffic Authority. Such the dependent variable as number of truck accidents and the 24 independent variables as geometry, traffic volume and others are used. The main results are as follows. First, 5 Poisson models (${\rho}^2$ of 0.164~0.351) which are all statistically significant are selected. Second, the common variable based on type of accident and conflict is analyzed to be truck apron width. The specific variables are, however, evaluated to splitter island, area of splitter island, speed limit sign, truck apron, number approach road, circular intersection sign, speed hump and traffic volume. Finally, widening the truck apron width and improving the above specific variables are analyzed to be important for truck accident reduction at circular intersections.

The development of information technology leads to changes in various industries. In particular, the health care industry is more influenced so that it is focused on. With the widening of the health care market, the market of smart device based personal health care also draws attention. Since a variety of fitness applications for smartphone based exercise were introduced, more interest has been in the health care industry. But although an amount of use of mobile fitness applications increase, it fails to lead to a sustained use. It is necessary to find and understand what matters for mobile fitness application users. Therefore, this study analyze the reviews of mobile fitness application users, to draw key factors, and thereby to propose detailed strategies for promoting mobile fitness applications. We utilize text mining techniques - LDA topic modeling, term frequency analysis, and keyword extraction - to draw and analyze the issues related to mobile fitness applications. In particular, the key factors drawn by text mining techniques are explained through the concept of user experience. This study is academically meaningful in the point that the key factors of mobile fitness applications are drawn by the user experience based text mining techniques, and practically this study proposes detailed strategies for promoting mobile fitness applications in the health care area.

A numerical assessment using mesoscale-CFD (computational fluid dynamics) coupled A2C (atmosphere to CFD) model was carried out to analyze the variation of microscopic air flow pattern due to the construction of the Chilgok barrage in the Nakdong River. Scenarios with air flow patterns were classified into pre- and post-construction. The increased width of the river due to the construction of the Chilgok barrage induced obvious changes in moisture and the thermal environment around the river. However, air temperature variation was restricted within an area along the windward side in the numerical assessment. The impact of barrage construction on air temperature tends to be stronger during the nighttime than the daytime. It also stronger during the winter than the summer. In the simulation, the convergence of mesoscale wind is more pronounced after barrage construction than before. This is caused by the change of heat flux pattern induced by the widening of the river. Although this work is a case study with restricted atmospheric stability conditions that has several limitations in the numerical simulations, the impacts of the land-use changes brought about by the construction of the barrage in the river acceptable.

Climate change has directly impacted environmentally dependent first industry. The changes of amount and frequency of precipitation have caused unstable drinking water supply for grassland and feed crop, and have changed the variety of grassland and feed crop. Rising temperature has caused heat stress on livestock, which has impacted feed intake and livestock products, and also has threatened to the health of livestock by widening the range of sources of diseases. In order for livestock industry to confront climate change, new technology development for climate change adaptation and measures of greenhouse gas mitigation are essential. Agroforestry is the one of alternative measures to mitigate greenhouse gases and to adapt to climate change. Agroforestry is the way rearing livestock and cultivating plants in forest, which is suitable to Korea where mountain area is over 68%. Feedstock such as maize, soybean, rice, and grass grown by agroforestry would decrease feed cost. Agroforestry will decrease heat stress of livestock during hot weather and will be possible to pasture, which increases livestock welfare.

본 연구는 고단백뇨를 보이는 신장질환모델마우스(FGS/Kist mouse)의 사구체에 대한 미세구조학적 변화를 관찰하고자 수행하였다. 전반적으로 사구체내의 모세혈관은 주변부의 혈관사이세포(mesangial cell) 부위의 확장으로 인하여 관강이 좁아져 있었으며 관강내에는 점액양 물질들이 흔히 관찰되었다. 또한 사구체바닥판(basal lamina)이 모세혈관 사이의 공간쪽으로 돌출되어져 있는 소견들도 볼 수 있었다. 혈관사이세포 부위에는 주변부와 뚜렷이 구분되는 전자밀도가 높은 물질들이 많이 차여져 있었다. 한편, 사구체바닥판에 인접하여 존재하고 있는 발세포들(podocytes)은 세포질내 많은 공포들이 관찰되었고, 발세포들이 내고 있는 발세포발(foot process)들은 서로 융합되거나 소실되어 매우 불규칙적인 소견을 보였다.
