In this paper, we introduce an improved adaptive boosting (AdaBoost) classifier and its application, a disguised-face discriminator that discriminates between bare and disguised faces. The proposed classifier is based on an AdaBoost learning algorithm and regression technique. In the process, the lookup table of AdaBoost learning is utilized. The proposed method is verified on the captured images under several real environments. Experimental results and analysis show the proposed method has a higher and faster performance than other well-known methods.

With the five-day workweek system in bank and the increased usage of ATM(Automatic Toller Machine), it is required that the financial crime using stolen credit card should be prevented. Though a CCTV camera is usually installed in near ATM, an intelligent criminal can cheat it disguising himself with sunglass or mask. In this paper, we propose facial feature verification system which can detect whether the user's face can be Identified or not, using image processing algorithm and SVM(Support Vector Machine). Experimental results show that FAR(Error Rate for accepting a disguised man as a non-disguised one) is 1% and FRR(Error Rate for rejecting a normal/non-disguised man as a disguised one) is 2% for training data. In addition, it shows the FAR of 2.5% and the FRR of 1.43% for test data.

This paper analyzes the similarity of fashion in the 1920's and 1960's. Fashion is a reflection of Zeitgeist. The similarity of fashion appeared in the similar social ideal period. The fashion of the 1920's and 1960's have a lot of similarity in many respects. Androgyny was the new word. The woman cut her hair short, wore short skirt, and projected a self-confidence that was considered by many to be too masculine. The new fashions also appeared very youthful. The cult of eternal youth was born. The mature woman was no longer requested. Instead, in the face of changing lifestyles and extremely rapid technological development, taste ran in favor of a young, athletic, and mobile ideal. The new fashions do-emphasized curvaceous shapes through short dresses and short hair-both styles were supposed to express youthfulness. Characteristic of the times was the short loose dress: straight silhouette disguised feminine curves. The new dresses were invented for very young, slim, and wide-eyed women. The common Zeitgeist of the 1920's and 1960's represents the cult of youth and the adoption of innovative style, which emphasized decoration-cleared simplicity, functionality, practicality, activity, androgyny. Innovative short skirt, youth fashion, androgynous style, unisex style, tubular silhouette, short hair style, and eyeline-emphasized makeup were analyzed by the similarity of fashion in the 1920's and 1960's.

Under the economic banner of "self-reliance," North Korea has focused on hydro and thermal power as its main energy supply sources. However, in the face of extreme energy penury caused by machinery and material supply instability in the wake of the collapse of the former communist block as well as equipment aging and deterioration due to floods and other disasters, North Korea and international aid organizations are increasingly turning their attention toward energy source diversification. In particular, renewable energy is recognized as the best strategic energy source for North Korea and it is a decentralized energy option that is suitable in light of North Korea's power distribution networks and its pursuit of self-reliance. Biogas can contribute to improving the human rights situation of North Koreans in conjunction with an increase in food production. For this reason, renewable energy is the most promising option for an energy source that is likely to secure humanitarian aid from international organizations such as the Food and Agricultural Organization (FAO) and the World Food Programme (WFP). However, the implementation of such humanitarian aid has been hampered by rising concerns about the diversion of provided energy materials for military purposes and the disguised introduction of dual use items strategic materials as well as UN Security Council resolutions and sanctions of the international community against North Korea's military provocation, including nuclear tests and missile launches. This paper explores the possibility of solving this dilemma and proceeding with the humanitarian aid to North Korea by evaluating the potential for sanction and the risk of diversion of the possible products for biogas-related aid on the basis of the list of UN-sanctioned items.
