This study was carried out to investigate the effects of water on the physical characteristics of dough for making white bread The results of the farinogram, the extensogram, and the amylogram measured were as the follow 1. In the farinogram pattern, the water absorption of dough were SW 71.2%, CW 70.9%, and DW 70.5%. water absorption of dough in SW was higher than CW and DW 2. In the development time, both SW and CW showed stability of dough because SW and CW taken 6 minutes whereas DW taken 2-3 min. In the extensogram, the resistance of dough was DW 520 B.U, CW 580 B.U, and SW 560 B.U, and thus CW and SW show excellence in keeping CO_2 formed by dough fermentation since their R/E (Resistance/ Extensibility) ratio was higher than R/E of DW. 3. By the amylogram of analyzing α-amylase activity, the highest viscosity was SW 700 B.U, DW 510 B.U, and CW 525 B.U, which showed SW might have the highest effect in enzyme stalling and starch decomposition in the baking stage.

고성식,김민호 서원대학교 교육대학원 1999 교육논총 Vol.3 No.-
This study examined the effects of 8-week plyometric training on isokinetic muscle function and vertical jump in the lower limb. These parameters were compared before and after training. The subjects of this study were participated in plyometric training calss who were physically trained university students. Plyometric training was performed at 5 exercise type for 30minutes per day, three days per week. The results of repeated measurement t-test showed that knee flextion and extension of CON were not significantly changed. However, knee flextion of ECC were incresed significantly for 120°/sec and 180°/sec, respectively. Knee extension of ECC were increased significantly for 60°/sec and 120°/sec, respectively. There were significant differences between pre and post tests on vertical jump. The results suggest that plyometric training was effective for increasing vertical jump.
Intelligent and Robust Face Detection

A face detection in color images is important for many multimedia applications. It is the first step for face recognition and can be used for classifying specific shots. This paper describes a new method to detect faces in color images based on the skin color and hair color. This paper presents a fuzzy-based method for classifying skin color region in a complex background under varying illumination.. The Fuzzy rule bases of the fuzzy system are generated using training method like a genetic algorithm(GA). We find the skin color region and hair color region using the fuzzy system and apply the convex-hull to each region and find the face from their intersection relationship. To validity the effectiveness of the proposed method, we make experiment with various cases.
Optimal Normal Bases and Low Complexity Normal Bases of Finite Fields
Min, Cheong Sick 호남수학회 1996 한국수학학술지 Vol.13 No.1
In secret encription and decription of digital messages, computation of GF(2^n) is required. Its arithmetic logic is central in some cryptographic algorithms. A major concern for the design of a VLSI to implement regular architecture is the interconnection of resisters to obtain multiplication of GF(2^n). A normal bases can be selected which requires much less connections from any A resister cell to C resister cells by appropriate choice of a transversal.
An Algorithm for Finding Boolean Matrices of Normal Basis

유한체 GF(2^n)은 수학 자체로서의 중요할 뿐만 아니라 원소의 개수가 2^n이 말해주듯 부호이론, 암호론, 스윗칭 회로 등에 이론에 중요한 도구가 되어 왔다. 본 논문에서는 저 복합성 정규기저에서의 곱셈연산을 대표하는 부울행렬의 구성을 메모리 공간과 속도를 최적화 하기 위하여 가우스 소거법을 사용하지 않고 희귀 행렬을 적용하여 구성하는 알고리즘을 제시하였다.
A GROUP ORIENTED CRYPTOGRAPHY WITH PARTICULAR MEMBERS
MIN, CHEONG-SICK 호남수학회 2001 한국수학학술지 Vol.18 No.-
Cryptography is traditionally associated with maintaining the secrecy of a message when the means of communicating or storing, that message may be subject to misuse by an attack. In group oriented cryptography, the sender of the information is allowed to determine the encryption/decryption keys as well as the information destination without any coordination with receiving group. The receivers may authenticate themselves for legitimacy of the information from the cipher text. The security of the scheme is based upon the difficulty of solving the discrete logarithm problem.

Purpose Tc-99m ciprofloxacin is available for imaging infection. However, there has been no study on employing single photon emission computed tomography (SPECT) with using Tc-99m ciprofloxacin to image active pulmonary tuberculosis. Therefore, we conducted this study to assess the efficacy of Tc-99m ciprofloxacin SPECT for imaging active pulmonary tuberculosis. Methods Twenty-one participants were enrolled in this prospective study. They were divided into two groups according to the clinical and radiological assessment. Group one (Gr. 1) consisted of five normal volunteers and six patients with inactive pulmonary tuberculosis. Group two (Gr. 2) consisted of ten patients with active pulmonary tuberculosis. SPECT was performed 3 h after injecting 555 MBq (15 mCi) of Tc-99m ciprofloxacin. The findings of Tc-99m ciprofloxacin SPECT were interpreted by a nuclear medicine specialist and then the results were analyzed according to the patients' clinical and radiological classifications. Results The results of Tc-99m ciprofloxacin SPECT were as follows: eight true-positive cases, ten true-negative cases, one false-positive case and two false-negative cases. The sensitivity and specificity was 80.0% and 90.9%, respectively. The positive predictive value was 88.9% and the negative predictive value was 83.3%. Conclusions Tc-99m ciprofloxacin SPECT is feasible for imaging active pulmonary tuberculosis. It is a useful nuclear-imaging method for discriminating between the active and inactive tuberculosis states in patients with a past medical history of pulmonary tuberculosis.
