  • Security vulnerabilities have been reported in major design software systems such as Adobe Photoshop and Illustrator, which are recognized as de facto standard design tools in most of the design industries. Companies need to evaluate and manage their risk levels posed by those vulnerabilities, so that they could mitigate the potential security bridges in advance. In general, security vulnerabilities are discovered throughout their life cycles repeatedly if software systems are continually used. Hence, in this study, we empirically analyze risk levels for the three major graphical design software systems, namely Photoshop, Illustrator and GIMP with respect to a software vulnerability discovery model. The analysis reveals that the Alhazmi-Malaiya Logistic model tends to describe the vulnerability discovery patterns significantly. This indicates that the vulnerability discovery model makes it possible to predict vulnerability discovery in advance for the software systems. Also, we found that none of the examined vulnerabilities requires even a single authentication step for successful attacks, which suggests that adding an authentication process in software systems dramatically reduce the probability of exploitations. The analysis also discloses that, for all the three software systems, the predictions with evenly distributed and daily based datasets perform better than the estimations with the datasets of vulnerability reporting dates only. The observed outcome from the analysis allows software development managers to prepare proactively for a hostile environment by deploying necessary resources before the expected time of vulnerability discovery. In addition, it can periodically remind designers who use the software systems to be aware of security risk, related to their digital work environments.

  • Background: We evaluated technique of hepatic resections using suprahilar-extrafascial dissection of Glissonean pedicle with vascular stapling device for pedicle transection with intent to minimize operative time and blood loss. Methods: We analyzed the clinical records of 326 patients who underwent anatomic liver resection by suprahilar-extrafascial pedicle isolation with vascular stapling division technique. Results: The minor liver resections were associated with significantly shorter surgery duration (105.1±21.1 vs. 225.6±75.6) and transection time (40.1±14.5 vs. 96.3±55.2) than major hepatectomies (p<0.0001 for all). The mean blood loss was 350.8±100.5 mL in minor resection and 485.4±250.2 mL in major resection (p=0.001). The mean blood transfusion requirement was 400.8±109.5 mL for minor resections and 550.9±100.0 mL for major hepatectomy (p=0.072). There was no significant difference in morbidity and mortality between groups (p=0.980; p=0.945). Major as well as minor liver resection were oncology superior with no significant difference in the 5-year overall survival rates. Conclusion: Suprahilar-extrafascial dissection of Glissonean pedicle represents an effective and safe technique of liver resection. Presented approach allows early and easy ischemic delineation of appropriate liver territory to be removed with selective inflow vascular control. It is not time consuming and it is very useful in re-resection, as well as oncological reasonable.

  • The Quality of physical therapy school system has conflicts between physical therpist, and reduces the opportunity of seguential education. So this study was investigated in order to made concrete the problems of educational duality, set up the direction of the school system's improvement, as like the four-year system and recognized the necessity. The curriculums of 13 colleges and 5 universities was analyzed. The curriculum analysis was made up the comparison and the analysis by a liberal arts point, a major point, a clinical practice point, total opening subjects, and so on. The analyzing results were as follows. 1. The average rates of a liberal arts vs. a major opening point are 17:83 in college, and are 27:73 in university. 2. It is a serious problem that college are lower than university in a liberal arts. The best method that can solve it is lengthen the number of school years. 3. There is no difference between college and university in a major subject. Rather college has the more subject's numbers than university. 4. There is no difference between college and university in a clinical practice. Above results suggests that there is not different between college and university in a major subject except for a liberal arts point. It is proper that one should be unificate the curriculum according to the sameness between a state examination and a license. Therefore, it is necessary for graduates from college that provides the opportunity of proceeding to a higher school, demands the seguential system of study cultivating and producing a bachelor, and requires the continual education in a clinical field, a bachelor admitting system of continual education, and clinical therapist's qualification. The present physical therapy educational systems should be unificated because of many right reasons. On the other hand, the follw-up study that improving the school system about the four-years and the more physical therapy should be continue from the viewpoint of education.

  • Fast and accurate diagnosis is needed to eradicate and manage economically important and invasive diseases like fire blight. Loop-mediated isothermal amplification (LAMP) is known as the best on-site diagnostic, because it is fast, highly specific to a target, and less sensitive to inhibitors in samples. In this study, LAMP assay that gives more consistent results for on-site diagnosis of fire blight than the previous developed LAMP assays was developed. Primers for new LAMP assay (named as DS-LAMP) were designed from a histidine-tRNA ligase gene (EAMY_RS32025) of E. amylovora CFBP1430 genome. The DS-LAMP amplified DNA (positive detection) only from genomic DNA of E. amylovora strains, not from either E. pyrifoliae (causing black shoot blight) or from Pseudomonas syringae pv. syringae (causing shoot blight on apple trees). The detection limit of DS-LAMP was 10 cells per LAMP reaction, equivalent to $10^4$ cells per ml of the sample extract. DS-LAMP successfully diagnosed the pathogens on four fire-blight infected apple and pear orchards. In addition, it could distinguish black shoot blight from fire blight. The $B{\ddot{u}}hlmann$-LAMP, developed previously for on-site diagnosis of fire blight, did not give consistent results for specificity to E. amylovora and on-site diagnosis; it gave positive reactions to three strains of E. pyrifoliae and two strains of P. syringae pv. syringae. It also, gave positive reactions to some healthy sample extracts. DS-LAMP, developed in this study, would give more accurate on-site diagnosis of fire blight, especially in the Republic of Korea, where fire blight and black shoot blight coexist.

  • Objectives : This study was to suggest the basic data to develop the national exam contents for dental hygiene by comparing with those of other country. Methods : Several dental hygiene education course results were reviewed, and analyzed the culture subjects, basic major subjects, educational subjects, national exam contents in 3 or 4 years dental hygiene curriculum. Results : In Korea, grades of culture subjects in dental hygiene curriculum were different between 3 and 4 years education course, mean grades were 10.4, and 34.5 respectively. While there were few different between 3 and 4 years education course, mean grades were 36, and 36.5 respectively in foreign country. In Korea, grades of major subjects in dental hygiene curriculum were similar between 3 and 4 years education course as mean grades of 110, while there were different between 3 and 4 years education course, mean grades were 60 and 80 respectively in foreign country. In Korea, number of major subject was higher in 4 years(n=61) than 3 years(n=54). However, it was lower in 4 years(n=27) than in 3 years(n=33) in foreign country. Total grade number was 129 in 3 years, and 145 in 4 years in Korea, while it was 97 in 3 years, and 116 in 4 years in foreign country. By analyzing 3 years education course, culture subject was 9.5%, basic health was 11.2%, oral biology was 11.2%, clinical dentistry was 20.7%, public oral health was 10.4%, oral hygiene care was 35.9%, management of dental clinic was 9.4%, education was 2.8% in Korea. In USA, dental hygiene examination contains practice work as major part, while theory was thought of as most important things in korea. Conclusions : It is necessary to improve learning course of dental hygiene curriculum on the basis of other country's system, and then it could be possible to development of good quality's national examination contents, thus good quality of dental hygiene personnel would be turned out in Korea.

  • It is estimated that sesame spread to Korea about B.C.1000 years and people cultivated sesame and ate sesame-oil age of three-nations. In the Koryo dynasty, sesame was cultivated as the major crop and there were specialists for making sesame oil. The sesame oil was enough for the both upper and lower classes. In the Chosun dynasty, it was introduced widely the method of sesame and deul-sesame (Perilla japonica) cultivation, the way of keeping sesame oil, and how to make sesame oil. Also, there were several ways of making sesame oil; press oil from raw sesame, or from roasting, boiling, and steaming sesame and etc. Even though sesame-oil and sesames were consumed in large quantities to cook Chan (찬 side dishes) and Byung-gwa (병과 Korean traditional dessert), most of common people could not use freely because it was expensive. You-mil-gwa (유밀과) took always a major dishes in the ceremony or party of the royal classes to the ordinary classes in the Chosun dynasty. Sesames and Sesame-oil made a major role in adding flavor to Chan-mul and Coookies in the Korean traditional cuisine. Especially, sesame-oil was consumed a lot to cook You-mil-gwa, You-kwa (유과), You-jeon-byung (유전병 fried rice cake) and Yak-bab (약밥). Roasted sesame and black sesame were used to cook Da-sik (다식), Gang-jung, and rice cake. Sesame oil and sesame was the major part of vegetable dishes such as Na-mul and it was used to add flavor to steamed, roasted and, pan-fried dishes and to roast, fry, and stew food. Heuk-im-ja-jook(black sesame porridge) and Im-ja-su-soup(임자수탕).
