최근 사물 인터넷에 대한 정보보호가 이슈화되면서 이에 적합한 알고리즘에 대한 연구가 활발히 진행되고 있다. 국내에서도 IoT환경에 적합한 경량 대칭키 암호 알고리즘인 LEA(Lightweight Encryption Algorithm)를 개발하였다. 본 논문에서는 LEA 암호에 대한 1차 전력 분석 방법들을 소개하고 이를 실험적으로 검증하였다. 그리고 1차 전력분석에 안전하도록 LEA를 설계하는 방법을 제안한다. 설계된 LEA 부채널 분석대응법의 효율성을 비교하기 위해 동일한 안전도를 제공하는 AES 부채널 대응법과 비교하였다. Recently, information security of IoT(Internet of Things) have been increasing to interest and many research groups have been studying for cryptographic algorithms, which are suitable for IoT environment. LEA(Lightweight Encryption Algorithm) developed by NSRI(National Security Research Institute) is commensurate with IoT. In this paper, we propose two first-order Correlation Power Analysis(CPA) attacks for LEA and experimentally demonstrate our attacks. Additionally, we suggest the mask countermeasure for LEA defeating our attacks. In order to estimate efficiency for the masked LEA, its operation cost is compared to operation time of masked AES.

Purpose : To investigate the inhibitory effect of BHE on platelet aggregation and erythrocyte deformability, we performed following experiments. Methods : Concentrated Boyanghwanotang (BHE) was fed to rats for 10days. High dose group was treated with $500{\beta}{\partial}/kg$ and low dose group with $500{\beta}{\partial}/kg$. Results : BHE enhanced the blood filtration rate, reduced the platelet aggregability, inhibited granule release from collagen-stimulated platelet, the prostaglandin syn-thesis in platelet and enhanced erythrocyte deformability. Conclusion : BHE should inhibit thrombos formation due to platlete hyperaggregabili-ty and reduction of erythrocyte deformabi-lity.

Acase of malignant schwannoma in the cervico-thoracic region with lung metastasis is presented. The patient was 55-year-old man presented with right arm weakness. Magnetic resonance image demonstrated lobulated enhancing soft tissue masses in spinal canal, neural foramen and right paraspinal space at C7-T1 level compressing the dural sac and spinal cord. Subtotal removal was performed and histological diagnosis of malignant schwannoma was made. Reoperation due to recurrence was done but subsequent metastasis to lung was observed.

본 연구는 영구임대아파트에 거주하는 노인 무료급식서비스의 만족요인을 확인함으로써 무료급식서비스의 질 향상과 효과적인 서비스 제공에 기여하는 것에 목적이 있다. 이에 본 연구는 M종합사회복지관 무료급식 이용자 183명을 대상으로 델파이조사와 AHP 조사를 진행하고, AHP 결과의 일관성이 높은 54명의 설문 응답자를 중심으로 2021년 9월부터 2022년 2월까지 연구를 진행하였다. 델파이분석 결과 무료급식 만족도에 미치는 중요 요인으로 음식의 맛, 음식의 양, 반찬의 가짓수, 위생상태, 배송시간, 조리식품, 간편식, 육류, 어패류, 채소류, 직원의 친절성, 안부 건강확인 총 12가지가 확인되었다. 델파이분석을 중심으로 우선순위를 확인한 AHP분석결과 위생상태 > 음식의 맛 > 조리식품 > 어패류 > 채소류 > 안부건강확인 > 직원의 친절성 > 배송시간 > 육류 > 간편식 > 음식의 양 > 반찬의 가짓수 순으로 나타났다. 본 연구는 노인들의 무료급식 만족에 미치는 세부 요인을 확인한 결과로서, 효과적인 무료급식서비스 제공을 통한 대상자들의 건강과 만족에 기여할 수 있다. This study confirms the satisfaction of free meal service for the elderly living in permanent rental apartments. The purpose of the study is to contribute to improving the quality of free meal services and providing effective services. Therefore, this study targeted 183 users of free meals at M Social Welfare Center in N-gu. The study conducted Delphi surveys and AHP surveys. 54 questionnaire respondents with high consistency in AHP results were centered. The study was conducted from September 2021 to February 2022. As a result of Delphi analysis, the factors affecting the satisfaction of free meals are as follows. There are a total of 12 types of food, such as taste, amount of food, number of side dishes, hygiene, delivery time, cooked food, convenient food, meat, seafood, vegetables, kindness of employees, and safety confirmation. As a result of AHP analysis, which confirmed priorities based on Delphi analysis, hygiene > taste of food > cooked food > fish and shellfish > vegetables > safety confirmation > kindness of employees > delivery time > meat > amount of food > number of side dishes. This study will contribute to the effective provision of free meal services by identifying the factors affecting the satisfaction of free meals for the elderly.

This thesis has been done as a part of work seeking how to deal with "religion" while studying and educating Chinese Culture. Although religion plays an important role on the formation and change of culture, it doesn"t seem that there is any appropriate studying and education going on in the Chinese culture academy. In this respect, our research will provide significant discussion to the Chinese culture academy. To make the proper discourse of religion in Chinese culture academic field, we have two long term goal: First, we will argue the Confucianism as a religion. Through this argue, we expect Confucianism would be referred in Chinese religion discourse. Second, we will investigate whether Confucianism still do an effect on Chinese as religion even in 21 century. In this thesis, we researched the first part of the goal. The summary of our research so far is as follows. Confucianism in Chinese culture corresponds to Christian religion in the western country. It is a fundamental idea that has shaped Chinese" thought and action for 2,500 years. But Chinese culture scholars hesitate to admit Confucianism as religion. Because their definition of religion has a certain limitation. The definition of religion can be divided in a two way: a substantive definition and a functional definition. A typical example of a substantive definition is to consider religion as "the faith for the spiritual being"(Tylor, 1871). According to this definition, Confucianism is not religion. The good example of a functional definition is that of A. N. Whitehead. "A religion can be defined as a system of general truths which have the effect of transforming humanbeing’s character when they are sincerely held and vividly apprehended."(Whitehead, 1926[2003:166]). According to this definition, Confucianism has been working as religion for Chinese. When studying religion, religion scholars prefer a substantive definition and sociology scholars prefer a functional definition. For culture scholars, it is more useful to choose a functional definition when they research the conduct and the habit of a man. Whitehead(1926[2003]) divides lots of religions into the following 2 types, and describes how each religion functions for the formation of human character. One is communal religion and the other is rational religion. The culture of a region which mainly believes rational religion tends to stress individualism and low-power distance. On the contrary, the culture of a region which believes religion of the community takes on collectivism, high-power distance. Through this, we can presume that religion and culture has considerable correlations. The biggest achievement through the research is that we could invite Confucianism to the Chinese religion discourse field. Though Confucianism has actually functioned as religion, it has not been admitted as religion in the view of substantive definition. Futhermore, it is another achievement of this study to get a model with which we can analyze the religious property of Confucianism.
