This paper proposes improved file encryption algorithm which represents image of grayscale type not using proper cover image for ciphertext. This method consists of 3-Tire encryption steps. 1-Tire and 2-Tire encrypt the information using existed stream algorithm and block algorithm with modyfied padding method. We propose the MBE method as 3-Tire, which hides structure and format of encrypted file. The proposed method outputs grayscale file as the result of encryption and since many GSF outputs resulted from different kinds plaintexts, have similar patterns. we obtain both file encryption and hiding the file information. Also, to solve the problem of padding in block algorithm, we propose the new padding algorithm called SELI(Select Insert) and apply 2-Tire block algorithm and MBE algorithm used 3-Tire.

Chordoma is an uncommon neoplasm that accounts for approximately 1% to 4% of all primary bone neoplasms and thought to originate from remnants of the fetal notochordal elements. It usually occurs in adults and has a predilection for the sacrococcygeal and spheno-occipital areas. Chondroid chordoma, first described by Heffelfinger et al, is a rare variant of chordoma; it contains both chordomatous and chondromatous features, and has a considerably better prognosis than either chordoma or chondrosarcoma. The cytologic findings of fine needle aspiration of sacrococcygeal chondroid chordoma in a 57-year-old man are presented. Aspiration cytology showed many sheets and cords of neoplastic cells in a thick amorphous blue-purple mucinous background. The cells had small too medium sized round nuclei with coarse granular chromatin and abundant eosinophilic or bubbly cytoplasm. Some cells had pleomorphic and hyperchomatic nuclei with prominent nucleoli. Cytologic findings were compared to histologic findings. Histologically, areas of chondroid differentiation were noted which were absent in the cytologic smear. Immunohistochemically, both the chondroid and chordoid areas had an epithelial phenotype and stained for cytokeratin, epithelial membrane antigen and S-100 protein. This is the first case of cytologic findings of chondroid chordoma to our knowledge in literature.

The author surveyed overall obesity indicies and factors concerned with obesity such as dietary intake, physical activity, stress and life style with the subject of doctors. The number of subjects was total 508 with 396 men and 112 women. They were subgrouped into surgical part, medical part and service and basic part by speciality. And also subgrouped into intern and resident, pay doctor, and practitioner by working type. The results were as follows. 1) Obesity indices: BMI of total doctor was $23.1{\pm}2.8$, and WHR was $0.87{\pm}0.08$ and overweight prevalence(BMI>25.0) was 23.6%. It was within normal limit but slightly over the Korean standard. The degree of obesity indices of subgroups by speciality was 'surgical part > medical part > service and basic part', and by working type was 'practitioner > pay doctor > intern and resident'. 2) Dietary intake and Physical activity: Average dietary intake was $2148{\pm}451kcal/day$. The degree of dietary intake by speciality was 'surgical part > medical part > service and basic part'. By working type it was 'practitioner > pay doctor > intern and resident'. Average physical activity was $29{\pm}5$ METs/day. The degree of physical activity also showed similiar pattern. But there was no significant difference among each groups. 3) Comparision between over-weight and non-over-weight group: The items that showed significant difference between two groups were dietary intake, skip breakfast, regular exercise, smoking, heavy drinking, chronic disease etc.

Crinum asiaticum Linne var. japonicum has long been used as a rheumatic remedy, an anti-pyretic, an anti-ulcer treatment, and for the alleviation of local pain and fever in Korea and Malaysia. In order to investigate the possibility of Crinum asiaticum Linne var. japonicum extract as a cosmetic ingredient, we measured its anti-inflammatory effect by inhibition of iNOS (inducible nitric oxide synthase), and the release of PGE2, IL-6, and IL-8. HPLC experiment after extraction with 95% ethanol at pH 3.5 showed that Crinum asiaticum Linne var. japonicum was mainly composed of lycorine (up to 1%), a well-known immunosuppressant. The content of lycorine varied depending on the type of tissue analyzed and the extraction method. In anti-inflammatory assay for inhibition of nitric oxide formation on lipopolysaccharide (LPS)- activated mouse macrophage RAW 264.7 cells, the ethanolic extract of Crinum asiaticum showed inhibitory activity of NO production in dose-dependent manner (IC₅₀ = 83.5 μg/mL). Additional study by RT-PCR demonstrated that the extract of Crinum asiaticum significantly suppressed the expression of the iNOS gene. Moreover, the extract of Crinum asiaticum did not show my cytotoxicity, but did show cell proliferation effect against LPS (10~60% increase of tell viability). In an assay to determine inhibition of the H₂O₂-activated release of PGE2, IL-6, and IL-8 in human normal fibroblast cell lines, the release of PGE2 and IL-6 was almost completely inhibited above concentrations of 0.05% and 1%, respectively. Moreover, the release of IL-8 was completely inhibited over the entire range of concentrations (> 0.0025%). The result showed that the extract of Crinum asiaticum Linne var. japonicum has sufficient anti-inflammatory effect. There-fore, Crinum asiaticum Linne var. japonicum extract may be useful as an ingredient of cosmetic products.

This research will compare the difference of visual analysis assignment performance skills of left hemisphere damaged apraxia patients. Methods: The targets of this research are a total of 9 patients with damage in the left hemisphere. 5 are patients who do not have apraxia and 4 are patients who have apraxia. With the visual analysis assignment made temporarily, the accuracy and response time were compared. Results: As a results of the accuracy comparison between the two groups, during the pattern recogni-tion, the recognition of triangle and square was the same, and there was no significant differ-ence in the accuracy of recognizing T-form and hand motions. However, the control group was significantly higher compared to the experiment group for the upper extremity motion accuracy. The response time did not show significant difference between both groups. Conclusion: Through this research, the patients with apraxia were more insufficient in recognizing the upper extremity motions compared to the patients with no apraxia. There is a need for research in the site of sensory information change based on the neurocognitive rehabilitation theory. (J Korean Society of Neurocognitive Rehabilitation 2013;5:29-34)

본 연구에서는 유아의 컴퓨터쓰기와 연필쓰기가 연령에 따라 차이가 있는지, 그리고 이들 간에 상관이 있는지를 알아보았다. 3세, 4세, 5세 유아 61명에게 개별면접을 실시하여 컴퓨터쓰기 표본과 연필쓰기 표본을 수집하였다. 컴퓨터쓰기는 양연임과 김영실(2001)의 컴퓨터쓰기 단계를, 연필쓰기는 Sulzby(1990)의 쓰기체제를 근거로 하여 분석하였다. 분석 결과 유아의 컴퓨터쓰기와 연필쓰기는 연령에 따라 차이가 있었으며, 연령이 증가함에 따라 발달하는 경향을 보였다. 컴퓨터쓰기와 연필쓰기는 4세 유아에게서 통계적으로 유의미한 상관관계가 있었다. This study examines whether age difference affects children's performance on writing with the computer and writing with the pencil and whether there is a relationship between the two writing skills. For this study, 61children aged 3 to 5 were interviewed individually and their computer and pencil writing samples were collected. Computer writing samples were analyzed on the basis of "Level of Children's Computer writing(Yang & Kim, 2001); pencil writing samples were analyzed on the basis of "Six Categories of Writing(Sulzby, 1990). The analysis showed that children on different age groups displayed different levels of competency in the computer writing and pencil writing skills and that the competency developed with the advancement in age. It also showed that there was a statistically meaningful correlationship between computer and pencil writing in the case of 4-year-old children.

The fruit or root of Ulmus davidiana var. Japonica and its extract has traditionally been used as anti inflammatation medicines as well as a remedy of the digestive ulcer for a long time. Ulmus davidiana var. Japonica has also been used to cure palliative and diuresis, because it contains lot of mucus and tannin. In this study, we examined the moisturizing effect and anti-inflammation effect of polysaccharides extracted from Ulmus davidiana var. Japonica to investigated whether it can be used as a cosmetic ingredient or not. The polysaccharides were extracted from Ulmus davidiana var. Japonica. Then the hydrolyzed was obtained through the hydrolysis. It has been ascertained that the polysaccharides we mainly composed of rhamnose, galactose, and glucose through HPLC experiments, and it has 20,000 of the molecular weight and 89.3 dL/g of intrinsic viscosity In a moisturizing test of measuring water loss in a desiccator and moisture content by Comeometer CM820, Ulmus davidiana root extract showed a similar moisturizing effect as hyaluronic acid. And its anti-inflammation effect on carrageenin-induced edema evaluated by measuring the thickness of swelling over paw induced by carrageenin (25 μL of 2% carrageenin saline injection), the % swelling over paw treated with Ulmus davidiana root extract was much less than that of paw treated with carrageenin only. The anti-inflammatory effect of Ulmus davidiana root extract was almost similar to that of ketoprofen. These results can say that Ulmus davidiana root extract can be effectively used as a cosmetic ingredient.
