  • In this study we surveyed the preferences of consumer packaging for mini pot flower plants to improve the flower market application in Korea. The surveys were consisted of the consumers residing in Seoul metropolitan (221), Gyeonsang (70), Jeonla (29), Chungceong (19), Gangwon (7), other provinces (3). A total of 349 eligible respondents (male 173, female 176) were surveyed with a self-administered questionnaire asking on the general characteristics for residents, packaging material, packaging design, type of flower pot, degree of transparency, convenience, consumer's demand for packaging development, a significant point when purchasing the flower pot product. The collected date was analyzed using a chi-square (${\chi}^2$) statistical test in SPSS program. Most residents prefer for mini pot flower plants packed with packaging characteristics of plastic material (56.4%), packaging design of separated type (76.2%), angled type (62.5%), and transparency (48.6%). The other question results showed that major consumer's demand for mini pot flower plants is maintaining the freshness quality and stability structure for them. Transparency of packaging can also affect directly the preferences for purchasing the mini pot flower plants. The packaging structure with a proper shape design may protect the fresh mini pot flower plants from shock or any other damage during distribution. The results of this study help to provide consumer's demand for packaging development and to give the greatest advantages in terms of production and marketability of mini pot flower plants.

  • Health policy is a historical product in the process of development, including the political and economic factors of the state as well as the social and cultural elements of the country. Bioethics began to debate the ethical questions that arise in the overall process of life's birth and death, and gradually evolved by presenting ethical directions for various social phenomena. Especially, according to the moral awakening of 'scientific medicine' which caused in some human problems in the rapidized scientific society from the late 19th century to the early 20th century, as a result of distress including the concept of various social relations, it is possible to say that it has reached the bioethics. Although health policy and bioethics are different in terms of starting and concept, they can be found in common with social, cultural, and political diversity in the times. In 2004, 'Bioethics Law' was enacted through the issue of research ethics in the life sciences. Therefore, in order to examine ethical aspects of current health policy direction and major issues, it can be divided into before and after enactment of 'Bioethics Law' in 2004. The authors would like to examine how the evolution of the ethical viewpoint on the health policy has changed in line with the enactment of the 'Bioethics Law' and how it is trying to solve it from an ethical point of view. Through the various events that took place in the 1990s and the 2000s, various discussions on bioethics were conducted in Korea. Prior to the enactment of the 'Bioethics Law,' ethical judgments of professions, distribution of healthcare resources, if the discussion focused on the ethical judgment of abortion, and the various events that appeared in the early 2000s became the beginning to inform that the ethical debate about the life, death, and dignity of human beings began in earnest in Korea with the enactment of the 'Bioethics Law.' Since then, 'Hospice and Palliative care Law' which was enacted in 2017, is based on the fact that the health policy of our country focuses on the treatment of the past diseases, health promotion, and delivery of health care services. It was an opportunity to let them know that even the quality problems were included. Therefore, considering the various circumstances, the ethical issue facing Korea's health care system in the future is the change of the demographic structure due to aging and what is to be considered as the beginning and the process of life in the overall process of life. It is the worry about how to die and when it sees as death. This has far exceeded the paradigm of traditional health care policies such as disease prevention and management and health promotion, and calls for innovative policy response at the national level that reflects the new paradigm, which in many cases creates a predictable ethical environment. And health policy should be shifted in the direction of future ethical review considering sustainability in the development process of future health care rather than coercive management.

  • A study on the optimum hydrolysis conditions of fish skin through the aid of enzymes and the development of a natural seasoning using the hydrolysate has been carried out for the effective utilization of fish skin. Using the "pH-drop" techniques the collagenase and pronase were identified as most suitable for this purpose. The $K_m$ and $V_{max}$ values of pronase were 1.82 mgN/ml and 0.06 mgN/mL/min, respectively. The hydrolysis conditions of the cod skin for the pronase were as follows: reaction temperature, $50^{\circ}C$; reaction time, 3hrs; pH 6; enzyme concentration, 0.03%. The degree of hydrolysis at these conditions was 76.8%. But after hydrolyzing cod skin with collagenase for 1hr, when the pronase was treated, the degree of hydrolysis was 83.13%. The molecular weight of the hydrolysate was 8,000 daltons. Among the amino acids in the hydrolysate, glycine(27.95%), glutamic acid(10.94%), proline(7.39%), aspartic acid(9.47%) and serine(7.39%) were responsible for 64.23% of the total amino acids. But valine, methionine, isoleucine, leucine, phenylalanine and histidine having a bitter taste were only 13.05%. From the results of the sensory evaluation, the imitation sauce which was made of 20% fermented soy sauce prepared from the hydrolysate was at least similar to the traditional soybean sauce in product quality. The complex seasoning containing 31.7% of the hydrolysate was nearly equal to complex seasonings on the market, too.

  • It is not simple to manage software quality, because software development process and product itself are very complex. Recently ISO/IEC 15504- international standard for software process improvement, capability determination and development - was completed and applied to many local trials, and their results are being reported as registered local trials. The first step of software process assessment is established by examining whether its base practices are performed and which level they are achieved. And as far as assessment responsibility and credibility are concerned, assessment is generally performed by team-based assessors. Therefore assessment team construction and its preference of practice importances have a great effect on the credibility and the objectivity of assessment. In this paper, we analyse a SPICE-based software process assessment trial by comparing base practice importances of assessed processes, which are expressed through a real assessment, with its final rating results. Survey data are collected from assessors and interviewees who were engaged in the SPICE trial that was performed by ISO/IEC 15504, and final data analysis are derived from the factor analysis method. It is convinced that the result of this paper is able to enhance the credibility of software process assessment by provisions of objective and rational criteria and preference information for assessment team construction and base practice importances in future.

  • It is important to realize automation services by communicating in IoT with humans, objects & objects, and forming a common network. People used web like the most powerful network way to sharing things and communication. Therefore the efficiency method communication between each device and the web in IoT could be different from ones. The best method for high quality software product in web applications is software reuse ; Modules, classes, patterns, frameworks, and business components are reusable elements of various perspectives. Components is plugged with others through well-defined interfaces, which can overcome the operation and complexity of application development. A web-based distributed environment for IoT applications is a standard architecture use information collected from various devices for developing and using applications. For that reason, the network management which manages the constituent resources for the best service control in IoT application is required as a sub-layer support service in most applications as well as individual applications. In this paper, we measure to develop a network management system based not only by components but on heterogeneous internetworks. For procedure this, we clarify a component architecture for classifying and classify also the component needed in the IOT and network domain or order the type of real network management system.
