The SOAP specifications are not provided a functions of information security, especially authentication function. In case of user authentication, delivery of the username and password elements can be exposed to sniffing/replay attack by malicious attacker. In this paper, we propose a new mechanism to protect authentication attacks for the SOAP messages. The proposed mechanism is compensated for weakness of S/KEY system. Our mechanism has no limitation for time and overhead and also provide a more effective and secure delivery.

일본 문화청 소속의 정부조직이었던 나라국립문화재연구소가 국가조직의 행정개혁에 따라 현재의 독립행정법인 나라문화재연구소로 변혁하면서 나타나고 있는 여러가지 상황에 대해서 살펴보고자 한다. 나분켄은 동아시아에서도 잘 알려진 국보 호류지금당벽화의 소실이 문화재 분야의 큰 문제로 부각되면서 종합적이고 학술적인 문화재의 연구 보호 종합기관의 설립 필요성에 의해 만들어진 기관이었다. 연구분야에서 보면 초기에는 역사, 건축, 미술공예, 정원, 유적 등 다양한 분야에서 출발했으나 나라지역의 헤이조큐 유적보존 문제가 주요 이슈로 떠오르면서 매장문화재의 발굴 중심으로 그 역할이 강화되는 변화를 겪에 되었다. 그러나 선사고고학이 아닌 역사고고학이 중심이었기 때문에 건축사나 정원사, 보존과학 등 서로 다른 학문이 융합하여 연구할 수 있는 강점이 강화되어 설립목적은 견지하면서 변모하였다. 독립행정법인으로의 변화는 1999년의 제145차 통상국회에서 "독립행정법인통칙법"이 성립되면서 부터였다. 독립행정법인의 취지는 독립 운영하는 쪽이 효율적인 부분을 분리시켜 법인격을 가진 기관으로 바꾸면서 운영교부금을 주무관청으로부터 받아 사용처를 독자적 재량에 맡기면서 이윤을 올릴 수도 있게 한 것이다. 또한 조직과 인사의 자율성을 보장받는 장점도 있으나 평가시스템이 되입되는 정신적 부담도 공존하게 된다. 즉, 민간 방법의 도입에 따라 국가의 부담을 경감하고자하는 의미가 내재되어있다. 나분켄의 독립행정법인화는 동시에 도쿄문화재연구소의 통합을 수반하게 되었다. 도분켄은 원래 미술공예품을 중심으로한 동산문화재 연구와 보존과학부분에 충실한 조직이었으므로 부동산문화재 중심의 나분켄과 통합에 우려의 목소리가 있었다. 그러나 불행중 다행으로 다카마쓰즈카 고분벽화의 열화문제와 키토라 고분 벽화의 보존문제로 인하여 전무후무한 협업연구가 진행되고 양 연구소의 역량을 결집할 수 있는 계기가 되었다. 결론적으로 말하자면, 독립행정법인화는 매년 예산을 중기계획이나 연도계획과 정합성을 유지하면서 독자적인 판단을 통해 편성하는 등 극히 유연한 대응이 가능하다는 장점을 가지고 있는 반면, 문화재 보존을 위한 연구라는 공공적인 목적을 가진 조직이 정부의 의도대로 독자적으로 이윤을 올리는 사업을 확립하여 국가의 부담을 경감하는 방향으로 나아갈 수 있는가라는 부분에서는 의심할 여지가 남아 있다.

In 2007, Long-Term Care Insurance Law was enacted to share the family burden of caring for the elderly who are unable to perform every day living activities due to their old age and chronic diseases such as senile dementia, diabetes mellitus, stroke and more. Backed by this law, since 2008, care workers have been sent to the elderly care centers or each elder's home to help them not only with their recovery from illnesses, but also with general activities from dressing, eating, bathing, walking even to toileting. However, according to the recently released survey by National Human Rights Commission, it has been found that the caring workers are in a very poor working condition including low income, abused blanket wage system, shortage of welfare services, extra works and even sexual harrassment. It is becoming an important issue due to fast-ageing population, the fact that the care workers have had experiences of violation in their right of labor while they are at work needs to be carefully treated. In that sense, this article presents some difficulties the caring workers face and proposes effective ways to solve these problems through the perspective of human rights and human labor rights based on the report written by National Human Rights Commission. In short, for this law to function properly and to boost the worker's capability of providing better services to beneficiaries, followings can be good answers - enhanced management and supervision on caring plans and care centers, providing immediate counselling and protection for victimized care givers, training courses offered to promote service receiver's sincere respect and strengthened awareness upon care givers.

Laws concerning the protection of personal information have been enacted and revised as the legislation on personal information protection on the basis of the Act on the Protection of Personal Information Maintained by Public Institutions. Nevertheless, there have been continuing threats resulting from the fact that restrictions on security subject to laws remain unclear. By proposing protected access utilizing a unique identification key of enterprises, regarding the personal information of various internal and external clients held by international manufacturing companies and attempting to make policy aspect and management access at the same time, there is a change of gradual decline in cloud personnel information management service, which is the domestic ISP service for personnel management as the technology facilitated to reduce the burden on personnel and cost for the protection of personal information and the market is also changing to the direction for companies to directly operate. Therefore, this study intends to examine the convenience of integrated management for ensuring security, while confirming the gap on flexibility and safety on management point regarding the human resources of international manufacturing companies arising from its interactions.

We follow the promising recent results of deploying the public key cryptography in sensor networks. Recent results have shown that the public key algorithms are computationally feasible on the typical sensor nodes. However, once the public key cryptography is brought to the sensor network, security services such like key authentication will be critically required. In this paper we investigate the public key authentication problem in the sensor network and provide several authentication protocols. Our protocols are mainly based on the non-solvable overhearing in the wireless environment and a distributed voting mechanism. To show the value of our protocols, we provide an extensive analysis of the used resources and the resulting security level. As well, we compare our work with other existing works. For further benefit of our protocols, we list several additional applications in the sensor network where our protocols provide a sufficient authentication under the constrained resources.

최근 인터넷의 급속한 발달은 온라인 뱅킹, 인터넷 쇼핑몰 등에서의 실물 경제행위를 온라인상으로 처리할 수 있는 환경을 제공하지만 온라인상의 업무처리는 개인정보유출, 개인정보의 위조 및 변조 등의 문제를 가지고 있다. 사용자가 CA에게서 받은 인증서의 공개키로 전자서명 함으로써 개인정보유출, 정보의 위조 및 변조 등의 문제를 해결한 PKI(Public Key Infrastructure)기반의 인증서 검증시스템이 제안되어 사용되고 있다. 인증서 상태검증 방법에는 CRL(Certificate Revocation List)기반의 검증방식, OCSP(Online Certificate Status Protocol)기반의 검증방식 등이 있다. CRL기반의 인증서 검증방식은 인증서 취소목록을 검색해서 인증서의 유효성 여부를 응답하는 방식으로 시간이 지남에 따라 크기 증가와 오프라인 방식으로 인해서 목록을 다운받는 시간의 부담으로 인해서 OCSP방식이 제안되었다. 하지만 OCSP 방식 역시 서비스의 요청이 집중될 경우 문제가 발생될 수 있다. 그래서 분산된 OCSP를 구축하고 각 서버의 부하의 균형을 유지하기 위해 로드밸런싱 기법을 사용하고 있지만 그 방법 역시 지속적인 서비스 제공이 불가한 문제를 가지고 있다. 본 논문에서는 서비스 요청의 집중으로 인한 시스템 마비나 각 응답서버의 부하가 불균형적임으로써 생길 수 있는 문제를 해결할 수 있는 방법을 제안한다.

Guilt feelings are dysfunctional feelings that the primary caregiver of the frail elder are apt to have and those feelings increase a burden of caring, while there is lack of empirical study on the effect of guilt feelings on caring behaviors. In light of this, this study lays its purpose on examining the effect of the primary caregivers' guilt feelings on their burden of caring and request behaviors for help with caring, paying attention to their guilt feelings in our society where Confucian values toward supporting the elderly have remained. The questionnaire survey was conducted for 220 primary caregivers caring frail elders over 60 years of age by visiting. As a tool for measuring guilt feelings, a self-designed measure for caregivers was used (${\alpha}=.949$), and factors of guilt feelings were classified into four namely, the factors of lack of self-control, lack of resources, burnout, and the normative factor As a result, the following findings were derived. First, it was revealed that the guilt feelings of caregivers as family members have a positive correlation with a feeling of burden of caring and the feeling of burden have even effects on the four factors of guilt feelings. Second, when primary caregivers request help with caring, they feel guilty toward cohabiting family members and neighbors, and also they show no guilt feelings when using day-care services for the elderly. Especially, guilt feeling factors affecting primary caregivers were found to be the normative factor to cohabiting family members, the factor of lack of resources to neighbors, and the factor of burnout to using day-care services for the elderly. This result tells that the dysfunctional feelings of primary caregivers namely guilt feelings arising when asking help with caring not only increase their burden of caring but also can cause difficulties in sharing the role of the caregiver. Accordingly for the mental health of caregivers, we should develop programs with which we could understand and cope with their guilt feelings.

Objectives: This study aimed to determine the effects on musculoskeletal symptoms of both social demographic features and detailed characteristics of each task category of care workers who offer visiting home-help services. And to establish the measures that can reduce musculoskeletal symptoms among care workers. Methods: This study was conducted among 192 care workers from welfare centers C and K located in city P. After participants completed the task burden checklist regarding the scale of musculoskeletal symptoms and the details of their duties, the data collected were analyzed using the SPSS 21.0 program. Results: According to the degree of observable musculoskeletal symptoms in care workers, the highest figures were observed for back and shoulder pain. Based on the results of assessing the effect of detailed task category characteristics on musculoskeletal symptoms, "helping patients eat, helping patients move, helping patients bath, and changing body positions" were found to have an effect from the physical care category, "providing physical therapy assistance, treating bedsores" from the health care category, and "cleaning and doing laundry" from the facility management category. Conclusions: Due to the high proportion of patients requiring burdensome physical labor from care workers such as moving patients who have trouble doing so on their own, helping them change positions, and so on, it is highly likely that pain will occur in the low back, which carries most of the physical weight. So, education on human epidemiological positions that can reduce overload on areas prone to pain such as the low back and shoulders is essential. Proper equipment and personnel support must be provided for dangerous tasks. Further, multidimensional social support is required consistently.

The advance of communication and networking technology enables high bandwidth multimedia data transmission. The development of high performance compression technology such as H.264 also encourages high quality video and audio data transmission. The trend requires efficient protection system for digital media rights. We propose an efficient digital media protection system using elliptic curve cryptography. Only key parameters are encrypted to reduce the burden of complex encryption and decryption in the proposed system, and the digital media are not played back or the quality is degraded if the encrypted information is missing. We need a playback system with an ECC processor to implement the proposed system. We implement an H.264 decoding system with a configurable ECC processor to verify the proposed protection system We verify that the H.264 movie is not decoded without the decrypted information.

Through the improvement of the Labor Relations Act, the Social Insurance Act, and the Artists Welfare Act for occupational status and rights of artists, the character of workers, joining exception in the Employment Insurance Act, and applying exception in the National Health Insurance Act and the National Pensions Act should be recognized. For this, the scope of workers should be expanded through the interpretation of the court and legislation of the Labor Relations Act, and supporting range of social insurance should be expanded by applying exception in the National Health Insurance Act and joining exception in the Employment Insurance Act for artists who are currently excluded. Artists' compensation insurance that is an optional entry system and paid entirely by artists need to have effectiveness of the system through insurance support. The Artists Welfare Act also needs to be revised to strengthen legal protection for artists and it is important to secure finances for artists' welfare projects. The standard contract should be mandatory and a career certification system for artists should be established so that artists who need welfare benefits can not be omitted.
