정진형,변근덕,이상진,Jung, Jin-Hyung,Byun, Keun-Duck,Lee, Sang-Jin 한국정보처리학회 2011 정보처리학회논문지 C : 정보통신,정보보안 Vol.18 No.4

최근 다양한 스마트폰이 개발 보급되면서 SNS(Social Network Service)를 사용하는 사용자 또한 급격히 증가하였다. SNS는 기존 모바일 기기에서 수집할 수 있었던 문자 및 통화내역과 같은 단순한 사용자 데이터 외에도 주고 받은 사진 및 동영상, 음성쪽지나 위치 공유, 대화 내역 등 다양한 정보가 저장되어 디지털 포렌식 관점에서 유용한 데이터 획득이 가능하다. 본 논문에서는 최근 많이 사용하고 있는 아이폰을 대상으로 스마트폰에서 이용할 수 있는 SNS 클라이언트와 각 클라이언트 별로 수집할 수 있는 데이터의 종류를 살펴본다. 또, 각 데이터간의 연관관계를 통해 수집된 데이터의 효율적인 분석 방법을 제시한다. As a diverse range of smartphones has been recently developed and diffused, the users of SNS (Social Network Service) also have been sharply increased. The SNS saves a variety of information such as exchanged pictures and videos, voice mails or location sharing, chat history, etc. as well as simple user data, so that the acquisition of data that are useful in the aspect of digital forensic is achievable. This thesis reviews the types of SNS that are available for the iPhone, a recent example of highly used smartphones, and types of data by each client. Also, efficient data analysis method for digital forensic investigations is suggested by analyzing the relationships within the collected data by each client.

한우고기의 포장방법이 저장성에 미치는 영향을 구명하기 위하여 500㎏ 내외의 한우암소를 도살하여 24시간 숙성하고 좌우 도체에서 각각 제5번째 흉추와 제7번째 요추 사이의 등심근을 발골하여 과도한 지방이나 결체조직을 제거한 후 1.8㎝ 두께의 스테이크로 절단한 것을 랲(PVC-wrap) 포장과 진공(Cryo-vac) 포장하여 4℃에서 35일간 저장하였다. 1. 총 세균수와 휘발성 염기태질소의 양은 저장기간이 연장될수록 증가하였으며 총 세균수를 107 cfu/g, 휘발성 염기태질소의 양을 20㎎% 이하로 각각 제한할 때 랲 포장육과 진공 포장육의 저장일수는 각각 7일과 21일이었다. 2. 육즙의 유출량은 차이가 있었다.(p<0.05). 3. 포장 직후에 포장방법 간의 차이는 있었으나 저장 3일 이후부터는 가열감량의 차이가 없었다. (p>0.05). 4. 랲 포장육과 진공 포장육의 연도는 저장 7일째는 9.83kg/㎠, 11.6kg/㎠까지 감소(p<0.05)하였으며 진공 포장육은 저장 21일에서도 8.43kg/㎠까지 감소하였다. 5. 육색의 명도인 L* 값은 포장직후의 랲 포장육이 39.88였으며 저장 14일까지 증가하다가 그 이후는 부패에 의하여 감소하였고 진공 포장육은 포장직후의 산소 결핍으로 35.63에 불과했고 저장기간이 경과 할수록 육색의 L* 값은 점차 증가하여 35일째에는 41.95를 나타냈다. 이와같은 결과로 볼 때 진공포장육과 랩포장육의 적정 저장일은 각각 21일과 7일 이라고 사료된다. This study was performed to investigate the effect of packaging method(vacuum vs wrap) on the self-life of Korean Native Beef called Hanwoo. M. Longissimus thoracis was taken at 24 hr postmortem, and evaluated pH values, total plate count, volatile basic nitrogen, objective color values, drip and cooking losses, and shear values during refrigerated storage with two packaging methods. According to the results of TPC and VBN, meats packaged with PVC-wrap were acceptable up to 7 days of refrigerated storage, whereas those with Cryo-vacuum package up to 21 days. However, increased cooking and drip losses were observed(p<0.05) during storage at 4℃. Vacuum packaged meat tended to have higher product loss(%), shear value, and darker(lower L*) than PVC-wrap packaged product during storage up to 28 days This result indicated that PVC-wrap packaging would be suitable for a short time-storage, such as domestic consumption, whereas vacuum packaged meats would be recommended for a long time-storage for export purpose.

This study was executed to find out how to improve the planting and use of landscaping plants in Chuncheon. The number of street trees was 17,877 in 2003. The major species of street trees were Ginkgo biloba(52.7%), Prunus sargentii(15.3%), Zelkova serrata(8.9%), Platanus occidentalis(7.3%). Salix babylonica and Platanus occidentalis were decreased, while Prunus sargentii and Zelkova serrata were increased. Salix babylonica is a good species for a lakeside city, but its seeds cause allergies to some people. Most of the trees have been removed in Chuncheon. The planting of Salix babylonica(♂) resulted in no problems, and it should be propagated to plant. The soil of several areas was analysed to investigate soil conditions. The outskirts of city had good conditions in pH, organic matter and minerals, but the downtown areas had high alkalic, due to alkali from footpath concrete blocks. Appropriate pruning adds to the aesthetic and prolongs the useful life; it also requires less managing of insects and diseases to maintain good healthy of street trees. Street trees were not properly pruned due to electric lines and shortage of pruning information. The pruning was controlled by Korea Electric Power Co, which has no pruning information. Pruning must be maintained by a professional landscape company to maintain good shape such as with Bonsai. The Shrubs planting zone between street trees and other trees, and preservation plates were established for healthy of street trees. They have to be repaired and maintained well to keep better environmental conditions. The number of tree and flower species of 68 schools in Chuncheon were 12 and 16, respectively. The species that showed high preference were Juniperus chinensis, Pinus koraiensis, Pinus densiflora, Rosa centifolia, Forsythia koreana, and Rhododendron schlippenbachii. The high frequency of the protection trees designated by Chuncheon were Pinus densiflora, Ginko biloba, Zelkova serrata, Quercus species. It was thought that the diversification of street tree species, the selection of street trees suitable to each space, the generalization of use of native species, the appropriate pruning and proper fertilization, the control of pests and diseases, and the opinions of citizens concerning landscape plants were needed to improve the planting, use and maintenance of landscaping plants in Chuncheon.

Recent research has focused on development of preditable procedures aimed at obtaining new connective tissue attachment to previously diseased root surfaces. Citric acid & tetracycline HCl treatment of exposed root surfaces have been shown to demineralize dentin and thus demineralization of the root surface resulted in greater all attachment. The purpose of this study is to compare the effects of tetracycline HCl and citric acid root treatments on the aspect of apical migration of epithelial cell, the degree of attachment of connective tissue, the new cementum formation & the degree of new alveolar bone formation around the grafted materials. When additionally the root surface is treated with citric acid or tetracycline & the Hydroxyapatite is grafted during the flap operation surgical alveolar defect was formed in lower right & left premolar area of adult dog. Experimental chronic periodontitis is induced by ligation the surgical alveolar defect with orthodontic wire. The control group is only performed flap operation while additional use of tetracycline or citric acid on root surface in the experimental group. Thereafter the experimental animals were sacrificed at 1, 2, 4, 8 weeks. After the histologic assessment was perfomed, the following results were acquired 1. The control group is similar to experimental group by the first week but thereafter apical migration of epithelium were seen and new bone formation were not distinct. 2. The new cementum formation & fibrous connective tissue attachment on the root surface were seen in citric-acid group & tetracyclin group and apical migration of epithelium was very delayed. There was no distinct difference between the two experimental groups. 3. In both group, new bone formation surrounding the graft material was observed but the rate of new bone formation of tetracycline group was superior to the citric acid group.
