네트워크 응용 프로그램을 개발하기 위해서는 Socket API를 많이 이용한다. Socket API를 이용해 정상적인 동작을 하는 것은 아주 쉽다. 실제 개발 과정에서 정상적인 상황이 아닌 여러 가지 비정상적인 오류에 처하게 됨에 따라 속수무책일 때가 많다. 따라서 각 플랫폼별로 비정상적인 오류들의 사례를 연구를 통하여 효율적인 응용시스템 개발의 필요성이 대두되었다.

현재의 조직 환경에서 정보 보호 수준의 결정은 필수 불가결한 이슈가 되고 있지만 정보 보호 수준 구축을 위한 기준은 상대적으로 부족한 실정이다. 이에 본 논문에서는 정보 보호 수준 결정에 있어서 기준이 될 수 있는 중요한 요소인 위험에 대해서 기존의 위험 평가 프로세스를 분석하여 개선된 위험평가 프로세스를 제시하고 허용 가능한 위험을 결정하기 위한 중요 기준인 목표 잉여 위험의 결정 방법에 대해 논하고자 한다.

This study was a case about improvement and system of management in park of Japan. Technique of Maintenance make a rapid progress. In the other hand, management was fall behind. Because of, its was not accept change of consciousness and variety of social factor. That is, not make clearly system of administration(organization, budget, etc.) for qualitative improvement of park. Besides, not make accumulation data of management and technique of maintenance. In future, need many study about system of management.

In this article an economic life test sampling plan is considered for repairable products when the products in each lot have the same interfailure time distribution, but the mean time between failure (MTBF) of a lot varies from lot to lot according to a known prior distribution. A cost model is constructed which consists of test cost, accept cost, and reject cost. Determination of the optimal plan which minimizes the expected average cost per lot is discussed. Numerical examples are presented to illustrate the use of the proposed sampling plans and sensitivity analyses for parameters of the prior distribution are performed.

The goal of automatic speech recognition is to study techniques and systems that enable agents such that computers and robots to accept speech input. However, this paper does not provide a concrete technology in speech recognition but propose a possible mathematical tools to be employed in that area. We introduce rough set theory and suggest the possibility of the rough set approach in phonetic distinctions.

This study is to review and re-establish LH disaster response and safety management system of the construction site and rental apartment complex in order to make an effective response and minimize damage in the face of disaster. I suggest directions for the improvement of disaster management systems. To achieve this, I reviewed the existing disaster response organization and accept opinions of the operating department in order to constitute effective organization which respond quickly and efficiently in emergency, and assigned new roles and responsibilities at each organization. Furthermore, I setup and suggested response manuals for each possible disasters.

It requires a lot of costs and manpower to manage an election. The electronic voting scheme can make the election system economic and trustful. The widespread use of smart phones causes mobile voting to be a major issue. The smart phone can be used as a mobile voting platform since it can carry out many services in addition to basic telephone service. To make mobile voting practical and trustful, we analyzed two subjects of study. Firstly, the way to make a biometric based mobile ID, which has legal binding forces. In mobile voting, user identification is accomplished on line since the voter should be able to vote wherever they go. The digital ID conducts a similar role to the need for a resident card. The user's identity is bound to the resident card legally. To bind the user's identity to the smart phone, we use USIM. Biometric recognition is also needed to authenticate the user, since the user cannot prove him or her on line face-to-face. The proposed mobile ID can be reissued by means of introducing a random secret value. Secondly, the mobile voting scheme is proposed where candidates can accept election results without doubt. The goal of an election is to select a leader among two or more candidates. Existing electronic voting schemes mainly focus on the study of ballot verification accomplished by voters. These approaches are not safe against collusion attacks where candidates and the election administration center are able to collude to fabricate election results. Therefore, a new type of voting and counting method is needed where candidates can directly take part in voting and counting stages. The biometric based multi-signature scheme is used to make the undeniable multi-signed ballot. The ballot cannot be verified without the help of all candidates. If candidates accept election results without a doubt, the fairness of the election is satisfied.

The purpose of this study was to investigate the attitude and wearing effect of brassiere wearing in 20's female college students. Particularly, by exploring the necessity of wearing a brassiere, the research was carried out to make it possible to use it effectively in the development of brassiere for women in their early 20s. In early 20s, the type of wearing brassiere in female college students was analyzed as three types: function-importance type, inconvenience-accept type, and wearing inconvenient type. Function-importance type, the brassiere corrects the silhouette of the upper body, has a push-up effect that collects the breast, and it was thought that it would not allow the nipple point to fall. By wearing a brassiere, there is a lift-up effect that reduces the vibration of the breast due to movement and raises the bust. Inconvenience-accept type wears a brassiere so that the breast volume can be improved and the nipple point is not visible. And they strongly agreed that the brassiere would wrap my breasts well and calibrate the upper body silhouette to make my body look pretty. However, they felt that their bust was troubled when they wore it, and they thought that their brassiere would be out of order due to their movements, so they had to wear brassiere for beauty, but they were uncomfortable. The wearing inconvenient type was analyzed as a type that the cup part was lifted, the sweat was not absorbed, and the heat was uncomfortable. It is thought that it is necessary to develop an effective brassiere for the function of raising and collecting breasts based on the body shape of women in their early 20s.

Recently, fisheries safety has been a matter of primary concern among consumers and suppliers. This phenomenon made them require the introduction of fisheries traceability systems. For traceability systems to be effective, automatic identification means play an important role. Therefore, RFID-based fisheries traceability systems are more required than barcode-based fisheries traceability systems. Unlikely EU and Japan, Korea did not accept mandatory traceability regulations. But Many countries began to accept mandatory traceability regulations to diminish food risks. So Korea is expected to adopt them in the near future. The purpose of this study is to find what benefits are generated from the adoption of RFID-based fisheries traceability systems and are related to their success. To do these, this study investigated primary benefits of RFID-based fisheries traceability systems from the perspectives of consumers and suppliers. Consumers' benefits were derived from the perceived risk dimensions. And suppliers' benefits were derived from operational benefits of RFID systems. To purify the benefits from RFID-based fisheries traceability systems, reliability and factor analysis were used. And the refined benefits of RFID-based fisheries traceability systems were additionally analyzed to find which benefits were significantly related to fisheries traceability systems' success. According to the analysis results, all risk dimensions except social risk were significantly related to their success. But in the benefits of suppliers, only "recalls and counterfeits" factor was significantly related to their success. These results implied that fisheries traceability systems should be based RFID technology instead of barcode and fisheries traceability systems were related to almost food risk dimensions. It's because these significant factors are related all food risks except social risk and the benefits of suppliers can be derived from only RFID technology.
