With growing population of internet and web applications, distributed environment is considered to be the standard architecture of application. A network management systems(NMS) is necessary to control and monitor the complex network resources for providing and sharing the heft quality service. We recognize the NMS as a standard infrastructure for supporting efficient networking and a separate commercial applications. We believe every resource including software, hardware and environment for the network management should be separated from special protocols, vendors and applications. Therefore, We need a standard network management system that is efficient and consistent because of the heterogeous network features. In regards to software development, software reuse through assembling and extending the reusable elements such as patterns and components assures to realize the best productivity and quality The component based development(CBD) methodology that can assemble black box though well defined interfaces makes it possible to develop easer and quicker applications and is proved as the best software development solution involved in construction, selection and assembly of components. In this thesis, we describe the architecture for the network management and identify, define and design the components through analysis and design in the network management domain and Identified components mapped to the component architecture. We also specify the component development and design and implement the component for developing the network management. Implemented components apply to the component repository system that register, retrieve and understand the components. We analyze, design and implement the entire network management system based on configuration, connection, performance and fault management through the pre-developed components.

The weight-to-power ratio of the standard truck for the climbing lane design is known to be 200lb/hp. The value was known to be assumed based on constant trucks' capability and regional distributions in stead of widely varied distributions region by region. Additionally, this value was assumed after investigating registered vehicles' statistics instead of investigating real portions of truck volumes. Therefore, it may be said that the value of the current standard truck does not reflect regional or industrial diversity and proportions of truck volumes. To resolve these issues, the present paper studies diversified standard trucks which consider regionally or industrially diversified and observed-volume based weigh-to-power ratios. For this purpose, individual trucks' weigh-to-power ratios obtained at toll-gates of national expressways were used. For regionally based study, the whole nation are divided into 8 regions, then each region is characterized by a unit of a weigh-to-power ratio. The applicability of each value is provided. Results show that the single value for the nationwide standard truck may be 208 lb/hp, 8 lb/hp higher than the current value of 200 lb/hp. Results also show that regional values ranged widely from 170 lb/hp to 230 lb, 30 lb/hp higher/lower than the current value. Conclusively, regional diversity of trucks' weigh-to-power ratios was identified then three types of standardized weigh-to-power ratios which may represent regional characteristics were suggested. As the diversified standard truck are applied to the design standard, two benefits are expected such as decrease of rear-end accident rates or decrease of climb lane construction costs.

Jeju province is the highest area about obesity(1st), alcohol consumption(2nd) and male smoking(2nd) among sixteen Korean provinces by the report of Statistics Korea: 2013 community health survey. Therefore, it is assumed that the incidence rate of colon, liver, lung and breast cancer can be high. The purpose of this study is to test these cancer's incidence and mortality trends and compare comparability with national average. The Joinpoint regression model and permutation tests for identifying changes and parallelism in trend were used to test registered data at Jeju Regional Cancer Registry from 1999 to 2012. In male colorectal cancer, Average Age Percent Change(AAPC) of Age-Standardized incidence Rate(ASR) was 8.4% per year(p-value<.000) and the hypothesis of parallelism with Korean male average was rejected because of steep increasing of Jeju male patients' AAPC(p-value=.047). In male liver cancer, AAPC of ASR was -2.98 % per year(p-value<.000) and parallelism with Korean male average was rejected because of sluggish decreasing of Jeju(p-value=.026). In male lung cancer, the ASR parallelism with Korean male average was rejected(p-value=.009) because Jeju patients APC(4.37% per year) was increased during 2006~2012. This study demonstrates that AAPC and Trends of male colon, male lung and male liver were difference from national average. Further studies are needed to understand its causes.

Objectives: This study was conducted to examine the educational needs of elderly hypertensive or diabetes patients and educators for the education program development of cardiocerebrovascular high-risk group in community. Methods: This study was conducted with 60 hypertensive or diabetes patients aged 65 years or above (cardiocerebrovascular high-risk group) who had registered KHyDDI(Korea Hypertension Diabetes Daegu Initiative) Project and attended Hypertension Diabetes Intervention Center Program, and with 44 educators in the center between June and August, 2009. Data were collected using questionnaires including general characteristics, educational objectives, curriculum, contents, and methods. Results: The major findings of this study were as follows: In education methods, cardiocerebrovascular high-risk group and educators both preferred small-grouped(5-9 persons) or individual education, 30min-1 hour, 50%-50% of theory-practice ratio, 3 months of education. In education contents, both groups needed all the suggested contents. Five categories would be suggested for the development of education program. The first category was that there was no significant difference between cardiocerebrovascular high-risk group's needs and knowledge. The second was category of low knowledge level in cardiocerebrovascular high-risk group's knowledge. The repeated education would be necessary for this category. The third was category with large standard deviation in cardiocerebrovascular high-risk group's knowledge. Individual education would be necessary for this category. The fourth category was that there was significant difference between cardiocerebrovascular high-risk group's knowledge and knowledge assessed by educators. The improvement of educator's education skill would be necessary for this category. The fifth category was that there was significant difference between cardiocerebrovascular high-risk group and educator's needs. Conclusions: Small group or individualized and staged education reflecting above cardiocerebrovascular high risk group and educators' needs should be developed for more effective education to prevent and manage the cardiocerebrovascular disease.
