화이트박스 암호 기술이 소프트웨어 콘텐츠 저작권 보호(불법유출방지)를 위한 핵심 툴킷으로 등장하고 있다. 암호 알고리듬이 동작하는 단말과 단말의 사용자는 믿을 수 있다는 기존의 생각에서 최근에는 암호 알고리듬이 동작하는 단말은 오픈 플랫폼이 되어감에 따라 사용자가 모르는 사이 단말웨어가 설치되어 동작할 수도 있고, 사용자가 악의적인 목적으로 암호 알고리듬을 분석하고자 할 수도 있다는 인식이 퍼져가고 있다. 따라서 암호 알고리듬이 안전하게 동작하고, 암호 키의 불법유출을 막기 위한 하나의 방안으로 화이트박스 암호 기술이 등장하였다. 이 기술은 기존의 보안 하드웨어를 이용한 기술과는 달리 소프트웨어만으로 암호 알고리듬의 중간 연산값 및 암호화 키를 보호할 수 있다는 장점 외에도 다양한 장점을 보유하고 있으며, 암호 알고리듬의 화이트박스 구현 방법에 관한 연구가 활발히 진행되고 있다. 본 고에서는 화이트박스 암호 기술의 탄생 배경 및 화이트박스 암호 기술의 개념, 그리고 이를 이용한 응용 기술에 관해 기술하고자 한다.

We have developed a high-$T_C$ SQUID magnetometer system to measure magnetocardiograms of laboratory rats. White noise of the measurement system was about 50 fT/$Hz^{1/2}$ when measured in a magnetically shielded box. We optimized the measurement position to obtain clear MCG wave from rat's small heart by using grid measurements. With the optimization, the MCG signal was successfully detected with the peak amplitude of about 50 pT. We could observe well defined P-, QRS-, and T-wave from the rat MCG. The results suggest that the developed system has a strong potential to monitor the progress of heart disease model using laboratory rat.

The purpose of this study is to investigate the Mourning Culture. In this study, methods such as field work, depth interviews and open-ended descriptions were employed to interpret their mourning culture. The results are as follows. This study classifies Mourning Culture by its filial piety, shroud, mourning garments and cremation. The death in the mourning have relation to filial piety. People began preparing their shroud after their 70th birthday anniversary. To keep prepared shroud naphthalene and leaf tobacco were placed inside. And to keep prepared shroud a paulownia tree box was used. The cloths of the shroud were mostly all Sambe(大麻). The color was light color center upon the white color and 素色. Terms of the shroud were different in each region. The kind of the mourning garments were various. The Cognition of the cremation was considerably affirmative.

Recent studies have indicated that mobile markets harbor applications (apps) that are either malicious or vulnerable, compromising millions of devices. Some studies indicate that 96% of companies' employees have used at least one malicious app. Some app stores do not employ security quality attributes regarding authorization, which is the function of specifying access rights to access control resources. However, well-defined access control policies can prevent mobile apps from being malicious. The problem is that those who oversee app market sites lack the mechanisms necessary to assess mobile app security. Because thousands of apps are constantly being added to or updated on mobile app market sites, these security testing mechanisms must be automated. This paper, therefore, introduces a new mechanism for testing mobile app security, using white-box testing in a way that is compatible with Bring Your Own Device (BYOD) working environments. This framework will benefit end-users, organizations that oversee app markets, and employers who implement the BYOD trend.

The presence of slime in paper mills is practically universal. Many researches have been performed for many years to resolve the problem caused by the slime in pulp and paper mill. Many papers have been published to show the bacteria is a major cause of paper mill slime. Now that the recycling of the water has been increased and the regulations of a toxic chemical dosage have become more strengthen, the importance of the control of slime in pulp and paper mill recently has been more recognized. Therefore, to produce quality products at the lowest economic and environmental costs, a through study of the microbial ecology and the indentification of troublesome slime-forming bacteria is a quite necessary. The purpose of this paper is to indentify slime~forming bacteria isolated from the papermaking process. The samples were taken from four parts of making fine paper : machine chest, head box, wire part, white water tank. Machine chest showed the most numbers of bacteria, numbering $2.55{\times}10^7$. The different colony types were taken from the 105 dilution plate. Nine bacteria were identified u sing the Biolog system and the vitek system: 6 gram-negative bacteria, 3 gram-positive bacteria. They are Pseudomonas paucimobilis B., Staphylococcus sp., Acinetobacter calcoaceticus., Pseudomonas cepacia, Actinobaci1lus capsulatus, Acidovorax sp., Flavobacterium sp., and Staphylococcus auricularis in addition to one unidentified sp., Among them. Pseudomonas paucimobillis was found in all places where the samples were taken. And, each parts had the different predominant bacteria in it : Pseudomonas paucimobilis B. in machine chest, Acinetobactor calcoaceticus. in Wire Part and Staphylococcus sp. in head box.

The purpose of this study is to analyze the articles of food and nutrition published in the Yeo-Sung magazines from 1936 to 1940 in Korea. Out of the 67 articles about the food and the nutrition from the Yeo-Sung magazines, 28 (41.8%) of them were about the brief information of food and nutrition news, 16 (23.8%) of them were about the recipes, 6 (9.0%) were about the nutrition information, and 17 (25.4%) of them were about others. As the number of recipes mentioned from the Yeo-Sung magazine was 103, 77 items, the majority, were about the Korean foods, 18 of the Western foods, 6 of Chinese foods, and only 2 of Japanese foods. This result showed that the Japanese colonization didn't seem to influence on Korean tastes and gastronomy. During this period, the modernization caused the numerous changes to our traditional cuisine with introduction of new western menu items and concept of nutrition. The nutrition articles highly recommended eating brown rice, vegetables, tofu, and the white meat. Shin-Young Bang, one of the main authors, insisted that "Cookery is not only the skill, but also the one of the very important academic sciences." showed budding modern cookery sciences in Korea.

The purpose of this study is to analyze how the women´s fashion with the design elements(silhouette, material, color, detail and trimming) of androgynous image which has appeared on our specialized fashion magazine from 1986 through 2000. As a result of this study I drew the following conclusion. 1. The bon silhouette led the market in the first stage of mid 1980. The wool and leather with the masculine image, cotton and soft material with unisex image were used to express the androgynous image. The dark and mono tone with the masculine image were used a lot in color. In women´s fashion the minimalism style with simple image was expressed escaping from the decoration, in which the detail and trimming was not found as in men´s wear. 2. It showed that more and more feminine image was accepted in the second stage of early 1990. Women´s wear silhouette with the androgynous image has changed from masculine box silhouette boomed in the first stage to hourglass silhouette and slim silhouette. The wool and leather were used a lot as the materials in the first stage but the usage of the cotton with unisex image and soft texture were getting increased. The main colors were the black and the blue but the usage of the white and the red were on the increase showing the range of the use was extending. In the meantime, the detail and trimming were hardly used like in the first stage. 3. In the third stage of the late 1990, the silhouette has changed to slim style. The wool and leather were mainly used as the materials but the cotton and silk were on the increase showing that the materials of the feminine image were used in the women´s fashion with the androgynous image as well as the materials of masculine image. In color, the black and the white of the masculine image were used increasingly by the effect of the minimalism and the usage of the colors were various for the rising frequency of the trend colors usage.

2008년 6월 상순 경남 진주시 농산물도매시장에 유통 판매중인 산딸기에서 이상증상이 발생하였다. 병징은 과실표면에 상처 또는 짓물러진 과실부분이 수침상으로 물러지면서 빠르게 부패되었다. 균총은 처음 흰색에서 연한 회색으로 되고 검은색의 포자낭을 많이 형성하였으며 균사생육 적온은 $30^{\circ}C$이었다. 포자낭경은 처음 흰색에서 연한 회색을 나타내며 폭은 $12{\sim}25{\mu}m$이었다. 포자낭은 검은색으로 구형 또는 반구형이며 크기는 $82{\sim}195{\mu}m$이었다. 주축은 반구형이며 크기는 $70{\sim}92{\mu}m$이었다. 포자낭 포자는 담갈색으로 단포이며 구형 또는 타원형이고 불규칙한 것도 있으며 크기는 $9{\sim}21{\times}7{\sim}8{\mu}m$이었다. 따라서 산딸기 과실에 발생한 병징과 병원균의 균학적 특징 및 병원성을 검정한 결과, 본 병해를 Rhizopus stolonifer에 의한 산딸기 무름병으로 명명할 것을 제안한다.
