블록 암호를 설계할 때, 설계자는 주로 차분 특성 확률의 상한을 이용하여 라운드 수를 결정한다. 라운드 수는 블록 암호의 성능에 영향을 미치므로, 더 적은 라운드를 갖기 위해 차분 특성 확률의 상한을 정밀하게 계산하는 것이 중요하다. 이전까지의 활성 S-box의 최소 개수를 탐색하는 방법들은 비선형 연산과 선형 연산을 각각 제약식으로 구성하여 차분 특성 확률의 상한을 계산하였다. 하지만 선형 연산이 비선형 연산에 의존적으로 선택되는 BOGI 설계전략(Bad-Output Good-Input Design Strategy)의 경우 이전 탐색방법으로 구한 상한은 정밀하지 않을 수 있다. 본 논문에서는 BOGI 전략의 성질을 이용하여 기존의 방법보다 더 정밀한 차분 특성 확률의 상한을 구하는 새로운 방법을 제안한다. 그리고 이 방법을 이용하여 구한 상한의 타당성을 수학적으로 증명한다. 제안한 방법을 BOGI가 사용된 GIFT-64와 GIFT-128에 각각 적용하여 9라운드까지 차분 특성 확률의 상한을 탐색하였다. GIFT-64의 7라운드와 GIFT-128의 9라운드에 대해 기존의 방법을 적용하면 차분 특성 확률의 상한이 각각 2^-18.395와 2^-26.885이었으나, 제안한 방법을 적용하면 각각 2^-19.81과 2^-28.3으로 더 정밀하게 계산된다.

The effects of Bogi, Boyang and Onri herbs on glutamate receptor using nystatin perforated patch clamp under voltage clamp were investigated and the following results was obtained. Ginseng radix and Astragali radix were chosen as Bogi herbs. Cervi cornu and Boshniakiae herba were used as Boyang herbs. Aconiti tuber and Zingiberis rhizoma were selected as Onri herbs. 1. $10^{-6}M$ of glycine brought about the increase of the ion currents by Astragali radix. Cervi cornu. Boshniakiae herba and Aconiti tuber to a minute extent that has no experimental meaning. 2. It was assumed that Bogi herb had no effect on glutamate receptor since the ion currents of Ginseng radix and Astragali radix that are Bogi herbs had not been inhibited to a great extent by D-AP5 and CNQX. 3. Boyang herbs were seem to have meaningful relationship with non-NMDA receptor since the ion currents by Cervi cornu and Boshniakiae that are Boyang herbs were inhibited by CNQX but not inhibited to a meaningful extent by D-AP5. 4. D-AP5 had not a significant effect on the ion currents activated by Onri herbs such as Aconiti tuber and Zingiberis rhizoma. CNQX had a significant effect on the ion currents of Aconiti tuber but no effect on the ion currents of Zingiberis rhizoma. Therefore, it seemed that Aconiti tuber had a relationship with non-NMDA receptor while Zingiberis rhizoma had no relationship with glutamate receptor. In summary, Bogi, Boyang and Onri herbs had different effects through different mechanisms on glutamate receptor. Hence it was believed that. through experiments on acetylcholine receptor new classification could be made.

The effects of Bogi, Boyang and Onri herbs on glutamte receptor, and the regulatory mechanism of cAMP-protein kinase on the ion currents activated by Bogi, Boyang and Onri herbs using nystatin-perforated patch clamp were investigated and the following results were obtained. Ginseng radix and Astragali radix, Cervi cornu and Boshniakiae herba, and Aconiti tuber and Zingiberis rhizoma were chosen as Bogi, Boyang and Onri herbs respectively. 1. The ion currents activated by $10^{-5}M$ of glycine were used as controls. The magnitudes of the ion currents by the above named herbs were as follows; Cervi cornu>Astragali radix>Aconiti tuber>Zingiberis rhizoma>Ginseng radix>Boshniakiae herba. 2. The magnitudes of the ion currents by $10^{-5}M$ of glutamate pre-treated with 0.01 mg/ml of Bogi, Boyang and Onri herbs were sharply decreased. 3. The activity of ion channels activated by Bogi herbs pre-treated with $10^{-7}M$ of staurosporin, an inhibitor of protein kinase, for thirty seconds was observed as the experiment proceeded. Staurosporin brought about dephosphorylation of ion channels. Hence, while the activity of ion channels activated by Ginseng radix was decreased, the activity of ion channels activated by Astragali radix was increased, as time went by. 4. The activity of ion channels activated by Boyang herbs pre-treated with $10^{-7}M$ of staurosporin, an inhibitor of protein kinase and an dephosphorylating agent of ion channels, for thirty seconds was investigated. While the activity of ion channels activated by Cervi cornu was increased, the activity of ion channels activated by Boshniakiae herba was initially increased then sharply decreased. 5, The activity of ion channels activated by Onri herbs pre-treated with $10^{-7}M$ of staurosporin, an inhibitor of protein kinase and an dephosphorylating agent of ion channels, for thirty seconds was investigated. While the activity of ion channels activated by Aconiti tuber was increased, that of ion channels activated by Zingiberis rhizomal sharply declined.

비선형 불변 공격은 비교적 간단한 구조의 키 스케줄을 갖는 경량 블록암호에서 필수적으로 고려되어야 할 공격이다. 간단한 구조의 키 스케줄을 갖는 경량 블록암호가 비선형 불변 공격에 저항성을 보이는 방법으로 가장 잘 알려진 것은 라운드 키 간의 차분 중 알려진 것들의 집합에서 선형계층에 대해 불변인 최소의 선형공간의 크기가 블록 크기와 같은지를 확인하는 것이다. 본 논문에서는 다음과 같은 연구 결과를 제시한다. 설계자 관점에서 비트 순열을 선형계층으로 사용하는 SPN 구조 경량 블록암호는 라운드 키 간의 차분의 종류가 한가지여도 비선형 불변 공격에 안전할 수 있음을 증명하고, 그러한 비트 순열의 형태와 개수를 제안한다. 또한, PRESENT 구조 블록암호는 비선형 불변 공격에 저항성을 갖기 위해 적어도 두 종류의 라운드 키 간의 차분이 필요함을 전수조사를 통해 보이며, 두 종류의 라운드 키 간의 차분을 필요로 하는 비트 순열을 사용해도 차분 공격에 대한 저항성이 오히려 증가할 수 있음을 보인다. 마지막으로 GIFT의 S-box를 사용하면서 BOGI 설계 논리를 유지하는 모든 비트 순열의 불변 성분 분포를 통해, 변형된 GIFT 구조 블록암호는 비선형 불변 공격에 저항성을 갖기 위해 적어도 8종류의 라운드 키 간의 차분이 필요함을 보인다.

Objectives : To find appropriate constitutional therapy by understanding Hyeong and Gi from the perspective that "Gi is inner position, and Hyeong is outer position, and Yang converts to Gi, Eum makes Hyeong(氣裏形表, 陽化氣 陰成形)". Methods : 1. Defined Hyeong(形)and Gi(氣)and studied Wonhyeong(圓形) and Banghyeong(方形), the shapes that are formed as a result of Gi-movement. 2. Used 'Hyeong-Gi' concept to analyze physiological and pathological phenomena; classifies parts of the body into Sasang by extrapolating from WonBang concept; and studied Sasangchejil. 3. Based on the above 1 and 2, studied medical direction of Sasangchejil written in Hwangjenaegyeongsomun Tongcheon Results : 1. Wonhyeong is the result of Yang(陽) movement, whereas Banghyeong is the result of Eum (陰) movement. 2. Hyeong(body) can be classified into Won(圓, circle) and Bang(方, square) or more specifically into Won of Won, Bang of Won, Won of Bang, Bang of Bang. Each corresponds to Taeyang(太陽), Soyang(少陽), Taeeum(太陰), and Soeum(少陰). 3. The constitutional therapy can be formulated by refering to "Tongcheon(通天)" and by taking into consideration that each Sasang constitution has a bias toward Mok(木), Hwa(火,) Gum(金), Su(水). Conclusions : Basic treatment for round shaped people needs to be focused on a cure of Boeum(補陰) and Bojeong(補精), whereas for angular shaped people, treatment should be about Bogi(補氣) and Boyang(補陽). Treatment for Taeyangin(太陽人) should be about strengthening Ganeum(肝陰) and reducing Paeyang(肺陽) and for Soyangin(少陽人), the treatment needs to be strengthening Sineum(腎陰) and diminish Biyang(脾陽). Taeeumin(太陰人) should receive a cure that reinforces Pyeyang(肺陽) and brings Ganeum(肝陰) down, whereas Soeumin(少陰人) should have a cure that strengthens Gi and increases Yang.

Background: The exposure to solar ultraviolet radiation is a significant risk factor generally underestimated by outdoor workers and employers. Several studies have pointed out that occupational solar exposure increased eye and skin diseases with a considerable impact on the lives and productivity of affected workers. The main purpose of this study was to evaluate the effectiveness against ultraviolet radiation of some measures recently undertaken for the protection of lifeguards in a coastal area of Tuscany. Methods: Different shading structures (gazebos and beach umbrella) were tested during a sunny summer's day on a sandy beach by means of two radiometers; the UV protection offered by some T-shirts used by lifeguards was also tested in the laboratory with a spectrophotometer. Results: The analysed shading structures strongly reduced the ultraviolet radiation by up to 90%, however a not always negligible diffuse radiation is also present in the shade, requiring further protective measures (T-shirt, sunglasses, sunscreen, etc.); the tested T-shirts showed a very good-excellent protection according to the Australian/New Zealand standard. Conclusion: Results obtained in this study suggest how the adoption and dissemination of good practices, including those tested, could be particularly effective as a primary prevention for lifeguards who are subjected to very high levels of radiation for long periods.

맞굿은 주로 10년 두리로 굿을 거행하는 영덕과 울진의 해안 마을에서 연행된다. 맞굿은 1)무당 맞이, 2)당신(堂神)에게 고함, 3)무당소개와 패기 보기 과정으로 이루어진다. 맞굿이 연행되는 이유는 마을에 따라서 당주가 없거나, 당주가 있더라도 큰굿을 연행할 능력이 부족할 경우 굿을 연행할 무당을 섭외해 맞이하여야 하기 때문이다. 당주무의 역량에 충분하더라도 별신굿은 많은 수의 무당이 필요하기 때문에 여러 무당을 섭외할 수밖에 없다. 따라서 항상 맞이해야 할 무당이 있을 수밖에 없고, 일부 경북 해안 마을에서는 그 무당들을 대상으로 하는 맞굿이 연행된다. 별신굿이 세월의 흐름에 따라 변화하듯이 맞굿 역시도 변화하고 있는데, 2000년대 이후 맞굿은 별신굿의 전체 일정이 갈수록 짧아지면서 2)당신에게 고함 3)무당소개와 패기보기 절차가 사라지고 있다. 2000년대 이후 맞굿에서 나타나는 또 다른 중요한 변화는 맞굿 연행 담당이 달라졌다는 것이다. 옛날에는 마을 사람들이 연행의 주체로서 부족하나마 그 역할을 성실히 수행했다. 그런데 최근에는 마을에서 점차적으로 농협 풍물단 등 외부에서 사물놀이패를 초청하여 맞굿을 연행하는 양상이 나타난다. 맞굿은 속(俗)의 영역에 있는 무당들을 성의 영역으로 편입시키는 일종의 통과의례로써 연행하게 된다. 또, 맞굿은 무당패의 능력을 확인하는 절차로도 활용되었다. 그러나 굿에 대한 인식이 전통 예술로 변화하고, '굿박사' 어르신들도 얼마 남아 있지 않다보니 점차 맞굿은 마을 외부의 존재인 풍물단과 무당패가 흥겨운 분위기를 만드는 정도의 절차로 변화하고 있다. 또 굿의 주관을 대부분 무집단에게 일임하고, 굿의 의미와 목적을 모른 채 연행되다보니 굿거리의 형식조차도 온전히 지켜지지 못하고 있다. 오랫동안 경북 동해안 별신굿의 주요한 특징으로 거론되어 오던 맞굿은 이제 과거의 그 목적과 기능을 점차 잃어가고 있으며, 이제는 한바탕 신나는 놀이판을 형성하는 굿거리로 변화하고 있다.
