  • 국가정보원 자료에 의하면, 산업기술 유출로 인한 피해액은 수십 조원에 이르고 있고, 피해유형은 내부자 유출, 공동 연구, 해킹, 불법유출, 위장합작 등으로 나눌 수 있으나 그 중 80%가 물리적인 보안과 연계된 내부자 유출로 나타나고 있다. IT와 비IT의 융합이 가속화되고 영역간의 경계 및 구분이 불명확해지면서 정보보호산업은 점차 지식정보보안산업으로 확대되는 개인정보보호중심으로 지속적으로 성장해왔으나, 향후 정보보호산업은 IT 보안기술 및 제품간 융합, IT 보안과 물리 보안간 융합, IT 융합산업보안으로 집중된다. 본 논문에서는 기업 정보유출 방지를 위해서 논리적 보안과 물리적 보안이 모두 동일 수준에서 관리되어야 하며, 특히, 물리적인 보안시스템(출입통제시스템, 영상보안시스템 등)과 IT 통합보안관제시스템의 융합으로 외부 공격 및 내부자 유출의 예방, 차단, 분석의 시너지효과를 극대화 할 수 있는 융합보안관제시스템 개선 모델을 제안한다.

  • Objective: As laying hens become aged, laying performance and egg quality are generally impaired. One of the practical methods to rejuvenate production and egg quality of aged laying hens with decreasing productivity is a forced molting. However, the changes in intestinal microbiota after forced molting of aged hens are not clearly known. The aim of the present study was to analyze the changes in excreta bacterial communities after forced molting of aged laying hens. Methods: A total of one hundred 66-wk-old Hy-Line Brown laying hens were induced to molt by a 2-d water removal and an 11-d fasting until egg production completely ceased. The excreta samples of 16 hens with similar body weight were collected before and immediately after molting. Excreta bacterial communities were analyzed by high-throughput sequencing of bacterial 16S rRNA genes. Results: Bacteroidetes, Firmicutes, and Proteobacteria were the three major bacterial phyla in pre-molting and immediate post-molting hens, accounting for more than 98.0%. Lactobacillus genus had relatively high abundance in both group, but decreased by molting (62.3% in premolting and 24.9% in post-molting hens). Moreover, pathogenic bacteria such as Enterococcus cecorum and Escherichia coli were more abundant in immediate post-molting hens than in pre-molting hens. Forced molting influenced the alpha diversity, with higher Chao1 (p = 0.012), phylogenetic diversity whole tree (p = 0.014), observed operational taxonomic unit indices (p = 0.006), and Simpson indices (p<0.001), which indicated that forced molting increased excreta bacterial richness of aged laying hens. Conclusion: This study improves the current knowledge of bacterial community alterations in the excreta by forced molting in aged laying hens, which can provide increasing opportunity to develop novel dietary and management skills for improving the gastrointestinal health of aged laying hens after molting.

  • Weather forecasting has become a very popular topic nowadays among researchers because of its various effects on global lives. It is a technique to predict the future, what is going to happen in the atmosphere by analyzing various available datasets such as rain, snow, cloud cover, temperature, moisture in the air, and wind speed with the help of our gained scientific knowledge i.e., several approaches and set of rules or we can say them as algorithms that are being used to analyze and predict the weather. Weather analysis and prediction are required to prevent nature from natural losses before it happens by using a Deep Learning Approach. This analysis and prediction are the most challenging task because of having multidimensional and nonlinear data. Several Deep Learning Approaches are available: Numerical Weather Prediction (NWP), needs a highly calculative mathematical equation to gain the present condition of the weather. Quantitative precipitation nowcasting (QPN), is also used for weather prediction. In this article, we have implemented and analyzed the various distinct techniques that are being used in data mining for weather prediction.

  • 지식근로자가 증가하고 정보의 종류가 다양해지며, 조직 간 정보의 교환이 빈번해질수록 기업 내부 정보관리시스템에 의존한 분석은 더 이상 효과적이거나 유용하지 않다. 이와 관련하여, 내부 지식정보시스템 뿐만 아니라, 외부의 정보공유시스템을 활용하는 방안이 최근 더욱 중요한 화두로 떠오르고 있다. 하지만, 조직 내외부의 정보공유시스템 사용에 대한 학문적 연구가 많지 않을뿐더러, 그 정보를 이용하는 사용자의 심리상태나 의도를 파악하는 연구는 거의 전무한 상황이다. 본 연구는 조직 내 지식관리시스템은 물론, 외부의 정보공유시스템을 이용하는 사용자 집단을 대상으로 심층 인터뷰 및 키워드 분석을 실시하여 그들이 가진 정보를 공유하려는 의도와 그 요인을 관찰하였다. 조사 결과, 내부 정보공유의 경우, 조직 내부에서의 업무와 관련된 정보를 공유하고 내부 구성원들 간의 소통을 원활하게하기 위한 목적이 대부분인 반면, 외부 정보공유시스템을 사용하는 목적은 자신이 보유한 정보를 공유함으로써 얻는 자기 만족감과 가치 있는 정보를 제공했다는데서 타인으로부터 얻는 신뢰감, 정보를 공유하는 행위로부터 얻는 순수한 희열과 같은 내재적 동기가 주로 반영되었음을 확인할 수 있었다. 본 연구를 통해 사용자들의 관심분야, 업무 관련성, 사용자 맞춤UI, UX의 개발, 구성원 간의 다양한 소통을 위한 커뮤니케이션 도구의 개발 등이 매우 중요하다는 실무적 함의를 도출하였다.

  • Purpose: This study aimed at exploring treatment delay (TD) among cancer patients in China with an attempt to develop a practical methodology facilitating frontline Chinese clinicians in promoting earlier cancer diagnosis and treatment. Materials and Methods: The study comprised framework development, qualitative interviews and paired factor rating. Framework development utilized systematic literature review, soft systems thinking and consensus groups. Qualitative interviews employed a checklist of open questions soliciting information about all the domains included the framework from cancer patients drawn via stratified randomized sampling of inpatients at 10 hospitals in Hefei, China. Paired factor rating used a self-developed computer aid and the interviewed patients as referring cases to weigh the relative importance of the factors listed in the framework in terms of their contributions to specific components of total delay (TD). Results: a) A conceptual framework was proposed consisting of a 6-step path to TD and 36 category determinants. b) A total of 227 patients were interviewed; their TD was 267.3 mean or 108 median days ranging from 0 to 2475 days; average appraisal, illness, behavioral, preparation and treatment delay accounted for 52.1%, 9.4%, 0.30%, 8.8% and 29.4% of the TD respectively. Individual side factors were rated substantially more important than environmental side factors (60% vs. 40%); most influential TD factors included cancer symptoms, overall health, family relations and knowledge about cancer and health. Conclusions: The framework proposed together with the interviewing and rating approaches used provide a potential new methodology for understanding cancer patients' TD and promoting earlier cancer treatment.

  • An American ginseng(Panax quillquefolium L) industry has emerged in British Columbia, Canada over the past ten years. Interest has grown very rapidly and with this development, attention is now moving away from field production issues and emphasis is being directed to enhancements in ginseng storage, drying and processing. There is a dearth of knowledge on these aspects even though they are crucial to international competitiveness. Enhancement dicatates the application of a systems approach to optimizing the harvest and post - harvest production system(crop digging, pre - washing cold storage. washing, drying and post - drying storage). Research in British Columbia to date has focussed on drying and storage issues and has resulted in the design of an enhanced commercial drying system. The role of dryer management, loading rates, airflow rates and pre - drying cold storage on American ginseng root drying rates and root quality were examined. From the dryer management experiments, there are distinct advantages to size sorting root to yield optimum drying rates. If unsorted root is used, efficiency is increased if the trays are systematically rotated. Loading rate experiments illustrate that increasing rates above those currently used in commercial dryers are possible without any sacrifice in quality. This has significant implications for commercial drying. Pre - drying cold storage is a most significant tool for managing drying operations. Over a period of six weeks, no discernable decrease in quality was found as a consequence of cold storage. Further, the moisture loss and the associated root surface changes(loss of surface soil in storage for example) provide new challenges for root quality management. Continued research and technological innovation will be crucial in addressing the demanding challenges of the future.

  • A tree-length harvesting system using the HAM300, which is mounted on a farm tractor prototype machine, have been recently introduced in South Korea for thinning old (>30 years) forests. However, no research has previously been conducted on the characteristics of residual stand damage associated with cable yarding systems on thinning treatment stands in South Korea. Therefore, there were assessed on the degree and quantity of residual stand damage caused by felling and yarding process to broaden the knowledge of residual stand damage on semi-mechanized skyline thinning operations. This study investigated scar size, direction, area, shape type and their distribution on the residual stand damage caused by felling and yarding operations. Damage to residual trees was generated for 7.4% and 6.9% of residual trees in felling and yarding operations, respectively. Damaged direction of scars was located in front-side (38.9%) and up-side (34.7%) for felling operations while the highest scar damage was found on down-side (44.6%) for yarding operations. Scar heights of felling damage were higher than those of yarding damage. In yarding operation, the most of the scars was located within l0m from the center of the skyline corridor. These results should be useful information for forest managers and landowners to reduce residual stand damages and retain valuable timber volume from thinning treatments.
