통계적 공정 모니터링에서 관리 상태일 때 품질 특성치의 모수값은 하나의 값으로 지정하는 경우가 대부분이다. 그러나 관리 상태로부터 공정 모수의 작은 변화는 실제적으로 크게 중요하지 않은 경우, 품질 특성치의 모수 영역은 관리 상태, 무관심, 그리고 이상 상태의 세 영역으로 구성될 수 있다. 이 논문에서는 3개의 모수 영역이 있는 공정에 적용할 수 있는 두 가지 지수가중 이동평균(exponentially weighted moving average; EWMA) 관리도 절차를 제안하고, 제안된 절차의 성능을 Shewhart 관리도 및 누적합(cumulative sum; CUSUM) 관리도와 비교하여 그 효율을 평가하였다.

본 연구는 이청준 소설 「눈길」을 통한 독서치유의 수업사례이다. 독서치유는 독서를 통한 동일화, 카타르시스, 표출, 통찰, 적용과정을 거쳐 진행된다. 연구를 통해 학생들은 소설 속 인물의 상황을 객관적으로 살펴보고, 이를 자신의 상황과 비교해서 바라보게 된다. 학생들은 소설 속 인물의 상황을 평가하고, '내가 만약 소설 속인물이라면 어떻게 할 것인지'에 대한 답을 통해 소설 속 인물의 다양한 삶의 입장을 경험하고, 자신은 그들의 삶과 다르게 살아갈 것이라는 자신의 의지를 표출한다. 그러면서 나와 부모님과의 관계를 들여다보고, 문제가 있는지, 있으면 어떻게 해결해나갈 것인지에 대해 진지하게 고민해본다. 이러한 과정을 통해 학생들은 자신의 감정과 문제의 상황을 살펴보고 해결할 수 있는 방법을 구체적으로 제시하게 된다. 결국 독서를 통해 학생들의 상처받은 감정은 일정부분 혹은 충분히 치유될 수 있는 것이다. 이 연구를 통해 독서치유의 방법이 좀더 구체화되고, 긍정적인 방향으로 발전하기를 기대한다.

It is generally believed that the medical profession in Korea is an well-paid field along with legal profession. In this vein, the nursing is regarded one of well-paid profession. The actual data, however, reveals that nurses belong to low income bracket. We carefully compare the nurse's earnings with those of other professions. We selected 58 professions, which are similar in vocational characteristics and education background to nurses and conduct a regression analysis to estimate earning functions. Using the estimated coefficients, we project an optimum salary level for nurse, and compare it with the actual salary level. The estimated results show that the nurses are underpaid : their actual salary is less than the optimum level. We provide several explanations for this phenomenon : a tradition based on Confucian value, wage discrimination for women, and wage inequality among hospitals. Undercompensation will result either ratard professional development, or block the motivation for high quality of nursing care. If the current underpaying situation is not improved, a shortage of nurses along with an noticeable decline in the quality of medical services are expected. Therefore an adequate compensation for nurses must be properly assessed and addresed not only be health care authorities but also by legislators. Further research is needed to explain why there is such as wide salary inequality among nurses, and to find what cause it.

The purpose of this paper is to compare seafarers' behavior according to traffic conditions of a road and an onshore locations. Behaviors are classified into three categories: Skill-, Rule- and knowledge-based mode. Experimental data were collected using the questionnaires for navigators, working in a merchant ship. To compare the behaviors, we used the four analysis method; the degree of frequency, reliability test, correlation and linear regression. As a result of the study, it was found that Skill-based behavior shows more higher in the road traffic than the maritime traffic, and rule-based behavior shows more higher in the maritime traffic than the road traffic. Also, the behavior in the navigation situation showed statistical significance. Especially, in the case of Rule-based behavior, a high correlation between road and maritime was found. This study can be expected to apply to complementary system utilization between error management system of onshore and maritime traffic.

As new types of medical devices are emerging through convergence with advanced technology, innovative technologies are becoming hot issues in health policy because of their disruptiveness. This study analyzed the innovative medical device management systems in the US, China and Korea. Innovative medical devices have been defined differently depending on the country's management system, but in common, they are defined as products that do not exist or have dramatically improved performance compare to existing products by applying innovative technologies. Innovative medical devices have been supported by regulatory authorities during product development and approval processes. While the US and China have more than 300 products designated as innovative medical devices with diverse functions, application fields, and manufacturing countries considering the initial situation of the implementation for the system, Korea has only 16 products, mainly radiology and diagnostic devices and made in Korea only as innovative medical device. In addition, Korea shows the highest market approval rate of innovative medical devices compare to the US and China, and it is necessary to prepare the approval process in consideration of product diversity.

The graying of population is not only a significant problem in developing countries, but also in a small country which is passing industrialization and urbanization. Industrialization and urbanization has raised a number of nuclear family. Moreover, changes in the environment and development in science such as a medical development and improving standard of health and hygiene have raised an average life expectancy. Considering these factors, average age of population is going up continue. Developed countries such as Europe, US and Japan have already experienced the graying and some countries have entered aged society. Korea is expected to be reached post-aged society in 7 years which is faster than developed countries that started aging society earlier than Korea. The purpose of this study is a analysis of resident's opinions and preference and using space of elders facilities and seeking a plan to construct the facilities through suggesting standard of use space. Firstly, this report will classify current situation of spacial organization on elder facilities focusing on major sectors and will compare in size. Moreover, standard of area distribution through an analyzing characteristics of each spacial organization. Secondly, The report will compare and analyze between space and main traffic line through classifying traffic lines between staffs and residents of elder facilities and understanding characteristics and problems of each traffic line. Lastly, this will study perception and preference on staffs at elders facilities and middle old aged people who are potential demander, and compare between these people.

This paper analyses a number of important areas relating to methane production in ruminants, consequent hazards and different methods of reducing this gas. Clearly methane not only affects on the environment but also on the economy of animal production. Several factors including feed, species, microbes, rumen environment, etc. are responsible for methane production in animals. Although methane production can be reduced by chemical manipulation, defaunation and strategic feeding, the latter was found to be effective because the method is easier to follow than the others. Furthermore, feeding technology could play an important role in reducing methane production particularly in developing countries because of its relative cost effectiveness. however, it needs to compare to what extent it could reduce methane production as well as cost of animal production. Therefore, research program needs to be concentrated on the appropriate feeding system to reduce methane production, consequently pollution and cost of production particularly in developing countries.

An informatization evaluation is becoming a major issue among vocational colleges, as the 21th century begins. This century is characterized as Knowledge and Information era. Thus it is popular for administrative organizations to use Information Technologies as major tool to innovate themselves. The main objective of this study is develop evaluation indexes on applications of information technologies for vocational colleges because they must operate their education services by using management principles. Four major indexes were recommended to evaluate their information environment of educational service as follows. 1. Strategic Information System 2. Environmental Factors of Information System 3. Informational Resources 4. Utilization of Information Technologies Each index has 4 variables to identify the level of informatization and every variable is consisted of several questions. Such an evaluation system will be applied for vocational colleges to know their own situation of IT application and to develop managerial strategies by using IT. This system also will be useful to compare you with your potential competitors and to find appropriate polices of IT application by measuring the indexes at different points of time.
