This study was performed to approach the 2004 case of inferior quality mandu stuffing from the stance of food ethics. The court convicted the producers of inferior quality mandu stuffing and also decided against the plaintiffs who filed a damage suit. The core of the mandu stuffing case was not safety, but the wholesomeness. The principles of food ethics include a respect for life, justice, environmental preservation, and the priority of safety. The virtues of food professionals include wisdom, honesty, faithfulness, courage, moderation, and integrity. A food producer should possess not only the ability but also the morality to make food. The consumer should urge the producers to strengthen their morality and be conscious of responsibility and fairness. The government should organize a system to establish food ethics, and make efforts to reduce wasteful law enforcement. The media should lead public opinion toward justice by doing an unbiased and in-depth report and help establish the idea of food ethics. The necessity of food ethics and the spread of the ethical mind are the most important points of all.

The purpose of this study was to identify attitude of hospital nurse's on death with dignity. The subjects of the study were 516 nurses. The data was analyzed by SPSS PC 19.0 program. 1) 82.8% participants agree to death with dignity, and they and their family will ask death with dignity in actual situations. 2) The average score of overall attitude on death with dignity was $3.13{\pm}0.52$. 3) With respect to the general characteristics of participants there were statistically significant difference in total score according to age, Marital Status, education level, religion, career, position, and existence of patients with incurable disease around. 4) With respect to the death with dignity related characteristics of participants there were statistically significant difference in total score according to agreement to death with dignity, request to my death with dignity, in case my family member requests death with dignity. Although many nurses had a positive concept of death with dignity, they still have ethical dilemmas in life-sustaining care. Therefore training programs on moral rights are necessary to provide guidelines foe end-of-life care.

In this paper, the biometric data is transmitted in real time from the IoT environment is runoff, forgery, alteration, prevention of the factors that can be generated from a denial-of-service in advance, and the security strategy for the biometric data to protect the biometric data secure from security threats offer. The convenience of living in our surroundings to life with the development of ubiquitous computing and smart devices are available in real-time. And is also increasing interest in the IOT. IOT environment is giving the convenience of life. However, security threats to privacy also are exposed for 24 hours. This paper examines the security threats to biological data to be transmitted in real time from IOT environment. The technology for such security requirements and security technology according to the analysis of the threat. And with respect to the biometric data transmitted in real time on the IoT environment proposes a security strategy to ensure the stability against security threats and described with respect to its efficiency.

PURPOSES: As pavement generally provides service shorter than an expected life cycle, maintenance cost increases gradually. In order to help extending the service life and reduce maintenance cost, a new multi-functional composite pavement system is being developed in Korea. METHODS: This study is a part to develop the multi-functional composite pavement and is to investigate the mechanical performances of fiber-reinforced lean concrete for pavement subbase. The inherent problem of fiber reinforced concrete is dispersion of fibers in concrete mix. This study additionally evaluated fiber dispersion characteristics with respect to different fiber types. RESULTS: From the test results, the compressive strengths of the concretes satisfied the required limit of 5MPa at 7days. The standard deviation of the measured number of fibers were lower in the order of nylon, steel fiber and polypropylene. CONCLUSIONS: Reject ash was shown to be satisfactory as a replacement material to Portland cement in lean concrete base. The fiber volume fraction is suggested to be 0.4% even though the fracture toughness did not vary significantly with respect to fiber types. However, fracture energy absorbed up to complete failure increased with the increased fiber volume fraction increment.

In this paper, the technique to reinforce the structure using the sensitivity information is proposed. Design variables related to the geometry of structure at fatigue fracture points are determined and sensitivities of fatigue life at fracture points with respect to the variation of design variables are calculated. Then the vector composed of gaps between the target life and initial life cycles at fracture points is calculated. The linear algebraic equation to solve the variation of design variables is composed. From the equation, the design variables for reinforced structure are determined.

We live seeing, touching, or throwing on considerable textile in our life consciously and unconsciously. Since a Korean-style house is a dwelling space in life style of sitting on the floor with ondol(Korean floor heater), use of textile is limited to bedding goods. However, as western life style takes firm root, use of textile for interior design is increasing. As well, as apartments and foreign style houses have gotten lodgment since 1980, life style is being changed rapidly. So, textile became required factors in dining space where little textile existed. Through literature, history of textile is considered and design image concept is created based on the consideration. In addition, the created concept can be applied to various textile design, which can be a good tool to express eating culture of the country as well as the country's image.

The dressing time monitoring in cylindrical grinding is very important with respect to machining efficiency. Therefore, the purpose of this paper is to determine the wheel life by monitoring behavior of grinding power for WA, 19A and GC. For this purpose , we investigated indirectly the attritious wear of grain edge, the loading of grinding wheel and the breakage of grain through the grinding power and the surface roughness under various grinding conditions. From obtained the results, the relationship between the wheel life and the average sectional chip area is examined to guide for the determination of dressing time.

In order to improve the fatigue lift of a lower control arm in the vehicle suspension, a new shape optimization procedure is presented. In this approach, the shape control point concept is introduced to reduce the numbers of shape design variables. Also, the two-level orthogonal way is employed to evaluate the design sensitivity of fatigue life with respect to those shape design variables, because the analytical design sensitivity information is not directly supplied from the commercial CAE softwares. In this approach, only the six design variables are used to approximate the shape of lower control arm. Then, performed are only 10 fatigue life analyses including the baseline design, 8 DOE models and the final design. The final design, the best combination obtained from the sensitivity information, can maximize the fatigue lift nearly two times as that of the baseline design, while reducing the 12 percentage of weight than it.

The Five Days Work System started to be lately introduced among Korean companies is causing much interests in diverse aspects. This theme of '5 days work' seems like a hot issue both for academian and for practitioner in the respect that it incurred a great change and impact in worker's life. The purpose of this article is to depict the pattern and the effect incurred by '5 days work system', focusing on the female workers in railroad-related organizations. To attain this purpose, several aspects of current '5 days work system' and its effects both on work life and on family life are surveyed through questionaire and analyzed by SPSS. And some implications will be supposed. in based on the cognitive response of employees.
