Since anti-forensics have been developed in order to avoid digital forensic investigation, the forensic methods for analyzing anti-forensic behaviors have been studied in various aspects. Among the factors for user activity analysis, "Iconcache.db" files, which have the icon information of applications, provides meaningful information for digital forensic investigation. This paper illustrates the features of IconCache.db files and suggests the countermeasures against anti-forensics utilizing them.

We have made disperse diazo black D(DB-D) ultrathin films using Langmur-Blodgett(LB) and vacuum-evaporation technique. Physical and electrical properties of the films were investigated. Solution was made with a concentration of 10$^{-3}$ mol/$\ell$ using chloroform. Moving wall apparatus (NL-LB140 S-MWC) was employed to make the LB films. X,Y and Z-type LB films were manufactured and studied by UV/visible absorbance spectra and morphology of surface using atomic force microscopy. Vacuum-evaporated DB-D think films were made at a pressure of 10$^{-5}$ torrr. The absorption peaks appear at 200 and 40nm in the LB films and vacuum-deposited films. And we have studied photoluminescence spectrum of the DB-D films. Also TGA and DSC properties of the DB-D have been observed and current -voltage characteristics of the DB-D LB films have been measured along the perpendicular direction.

HExDB is a database for analyzing exon and splicing pattern information in Homo sapiens. HExDB is useful for specific purposes: 1) to design primers for exon amplification from cDNA and 2) to understand the change of ORFs by alternative splicing. HExDB was constructed by integrating data from AltExtron which is the computationally predicted exon database, Ensemble cDNA annotation, and Affymetrix genome tile published recently. Although it may contain false positive data, HExDB is good starting point due to its sensitivity. At present, there areas many as 2,046,519 exons stored in the HExDB. We found that $16.8\%$ of the exons in the database was constitutive exons and $83.1\%$ were novel gene exons.

얼굴 및 얼굴표정 연구의 기초 자료를 제공하고 실제 표정을 디자인하는 작업의 지침으로 사용되도록 하기 위하여 대규모의 표정 DB를 구축하였다. 이 DB 내에는 여러 가지 방법으로 수집된 배우 24명의 자연스럽고 다양한 표정 영상자료 약 1,500장이 저장되어 있다. 수집된 표정자료 각각에 대하여 내적상태의 범주모형과 차원모형을 모두 고려하여 다수의 사람들이 반응한 내적상태 평정 정보를 포함하도록 하였으며 사진별로 평정의 일치율을 기록함으로써 자료 이용에 참고할 수 있도록 하였다. 표정인식 및 합성 시스템에 사용될 수 있도록 각 표정자료들을 한국인 표준형 상모형에 정합하였을 때 측정된 MPEG-4 FAP 기준 39개 꼭지점들(vertices)의 좌표값들 및 표정추출의 맥락정보를 저장하였다. 실제 DB를 사용할 사람들이 가진 한정된 정보로써 전체 DB의 영상자료들을 용이하게 검색할 수 있도록 사용자 인터페이스를 개발하였다.

Background: ginsenoside Rg5 is a rare ginsenoside with known hypoglycemic effects in diabetic mice. This study aimed to explore the effects of ginsenoside Rg5 on skin wound-healing in the Lepr^db/db mutant (db/db) mice (C57BL/KsJ background) model and the underlying mechanisms. Methods: Seven-week-old male C57BL/6J, SLC7A11-knockout (KO), the littermate wild-type (WT), and db/db mice were used for in vivo and ex vivo studies. Results: Ginsenoside Rg5 provided through oral gavage in db/db mice significantly alleviated the abundance of apoptotic cells in the wound areas and facilitated skin wound healing. 50 μM ginsenoside Rg5 treatment nearly doubled the efferocytotic capability of bone marrow-derived dendritic cells (BMDCs) from db/db mice. It also reduced NF-κB p65 and SLC7A11 expression in the wounded areas of db/db mice dose-dependently. Ginsenoside Rg5 physically interacted with SLC7A11 and suppressed the cystine uptake and glutamate secretion of BMDCs from db/db and SLC7A11-WT mice but not in BMDCs from SLC7A11-KO mice. In BMDCs and conventional type 1 dendritic cells (cDC1s), ginsenoside Rg5 reduced their glycose storage and enhanced anaerobic glycolysis. Glycogen phosphorylase inhibitor CP-91149 almost abolished the effect of ginsenoside Rg5 on promoting efferocytosis. Conclusion: ginsenoside Rg5 can suppress the expression of SLC7A11 and inhibit its activity via physical binding. These effects collectively alleviate the negative regulations of SLC7A11 on anaerobic glycolysis, which fuels the efferocytosis of dendritic cells. Therefore, ginsenoside Rg5 has a potential adjuvant therapeutic reagent to support patients with wound-healing problems, such as diabetic foot ulcers.

Characterization of a single pass of cDNA sequence, an expressed sequence tag (EST) has been a fast growing activity in fish genomics. Despite its relatively short history, fish EST databases (dbESTs) have already begun to play a significant role in bridging the gaps in our knowledge on the gene expression in fish genome. This review provides a brief description of the technology for establishing fish dbESTs, its current status, and implication of the ESTs to aquaculture and fisheries science with particular emphasis on the discovery of novel genes for transgenic application, the use of polymorphic EST markers in genetic linkage mapping and the evaluation of signal-responsive gene expression.

There are currently tremendous amount of geotechnical information saved, which has been qcquired for essential application of site selection, plan, design, constructin, repari in the builing work. However, due to the lack of the location data attribute, there has been a trouble in its analysis and GIS implementation. In this study, the geotechnical information aquisition program(PGeo) for real-time database in the field and geotechnical information reporting program(GeoReport) by Web-GIS for additional data input and its reporting function has been developed.

GIS was introduced to spatial information of complex and various facility systematically and scientifically. And, recently, new trend has been spread by Mobile GIS owing to its fast development of information and communication technology. However, these Mobile GIS techniques were introduced in maintenances of various facilities. Due to its mismanagement, the use became insufficient in facilities causing database creation to require realism and mobility. Therefore, in this research to road facility of various facilities, it deduced improving the work process by using a Mobile GIS to analyze work process of the road facility database creation. And, through an experiment, by comparing and analyzing road facilities database creation process by existing method and improving method, could improvement of road facility database creation using a Mobile GIS.

The Korea Democracy Foundation's archives offer its collection of records about Korean democratization movements through "Open-Archives," allowing users to read and use them conveniently. One particular article aimed to promote an overall understanding of its photo database to offer more promising services through the "Open-Archives." Similarly, many different archives hold photographic records, but they have difficulty releasing them to the public. Therefore, the present study introduced the case of Korea Democracy Foundation's project of building a photo database for Tony Chung in 2019-2020 to improve its establishment process, significance, and future tasks.

Obesity is caused by imbalance of energy intake and expense. If energy intake is more than its expenditure, body does fat accumulation and affects body weight. It can be fetal disease although obesity is not disease in itself. Central regulatary system is affected by many neurotransmitters regulating .food intake in brain. Hypothalamus was known as one of food intake regulation in CNS. In order to investigate gene expression difference in hypothalamus by different nutrient, we used C57/BL6 control mouse and db-/db- mouse. They divided each of two group with mouse, and fed control diet and high-fat diet for 4 weeks. Each of control and high-fat diet contained 11.7% and 59.7% fat, respectively. Then we performed microarray assay with them. We compared among changed genes in hypothalamus region. In the results, we observed that increased genes were more than decreased genes. Although hypothalamus size of db-/db- mouse is smaller than that of C57/BL6, more genes were affected in db-/db- mouse. In this study, many genes are affected by nutrient in hypothalamus region.
