  • The 7th National Education Process, implemented in 2004, features student-oriented, selective educational programs with a wide range of optional subjects. In 2005, reflecting this revised National Education Process, the College Scholastic Ability Test began allowing individual students to choose the subjects for examination they would like to take. As a result, the deviations of the college freshmen's academic achievements in some subjects have noticeably widened. This study shows academic abilities of the students on some subjects by comparing the results of 2008 College Scholastic Ability Test with that of the Basic Academic Ability Evaluation Test for freshmen in engineering college of Hongik university. Lastly, this paper presents some improvement plans in order to better accommodate students with academic achievement levels lower than what is expected by the university.

  • 객체지향 시스템의 개발은 클래스를 통해서 이루어진다. 즉, 문제 영역에 존재하는 중요한 대상 또는 개념을 클래스로 모델링하고, 이로부터 생성된 객체들 사이의 메시지 교환을 통해서 시스템은 구축된다. 또한, 클래스는 정보 은닉을 제공함으로써, 객체지향 시스템의 재사용성과 유지보수성에 상당한 기여를 한다. 그러나, 설계 단계에서 실세계의 대상을 부적절하게 모델링하거나, 또는 유지보수 단계에서 클래스에 무분별한 변경을 가하는 경우 클래스의 품질은 악화될 수 있고, 이는 결국 시스템을 유지보수 하거나 확장하는데 상당한 장애를 초래한다.응집도는 모듈의 구성 요소들 사이의 연관성 정도를 나타내는 척도로서 전통적으로 모듈의 품질을 평가하기 위한 기준으로 사용되어 왔다. 이 논문에서는 클래스의 품질을 평가하는 방법으로서의 클래스 응집도를 제안한다. 즉, 클래스가 실세계의 대상을 적절하게 모델링한다면, 그 구성요소들 사이에 밀접한 관련이 있고 결국 높은 응집도를 가지게 될 것이다. 반대로 실세계의 대상에 대한 적절한 모델이 아니라면, 그 클래스의 구성 요소들 사이에는 밀접한 관련성이 없을 것이고 따라서 낮은 응집도를 보일 것이다.Abstract Object-oriented systems are developed by means of classes; that is, classes captures the essential entities or concepts in the problem domain, and the system is embodied by the interactions of objects instantiated from the classes. In addition to the basic units of object-oriented systems, classes serves as the units of encapsulation, which considerably promote the modifiability and the extensibility of them. However, improper modeling in the design phase or uncontrolled changes during the maintenance phase can degrade the quality of classes, which leads to systems cumbersome to maintain and extend.Cohesion refers to the degree of connectivity among the elements of a single module, and is being used as a factor which characterizes the quality of a module. In this paper, we propose a new cohesion metric for assessing the quality of classes. If a class captures properly the essential features of objects, the members of the class surely have strong relationship among them. On the contrary, the poor relationship among class members can indicate that the class is not a proper model of objects.

  • The purpose of this study was to develop an understanding of older consumers' lifestyle, and to provide the basic information for developing silver commodities and, in turn, to stimulate the silver industry which has received attention as a next-generation industry. The study divided elderly consumers into four lifestyle categories and analyzed the difference in demographic characteristics among these categories as well as differences in demand for silver products. Data were collected with questionnaire and analyzed with frequency analysis, factor analysis, K-means cluster analysis, one-way ANOVA, and a $x^2$ test using SPSS 15.0. Four different lifestyles categories were identified among elderly consumers : conservative and stability oriented (22 persons, 33.3% of the sample), progressive and relation oriented (22 persons, 15.0%), reality adapted (52 persons, 35.4%), and traditional (24 persons, 16.4%). The demand for silver products demands was significantly different among elderly consumers in the four different lifestyle groups.

  • It is difficult to design system software to meet a better separation of concerns, which can provide a number of benefits such as adaptability, extensibility, and modularity in the design and implementation. During design, some aspectual properties, such as synchronization, scheduling, performance and fault tolerance, crosscut the basic functionalities of the system software. By separating functional components from the different aspectual components of the system software in the design, we can provide a better generic design model of system software. Aspect-Oriented Programming is a methodology that aims at separating components and aspects from the early stages of the software life cycle, and using techniques to combining them together at the implementation phase. In this paper we discuss an aspect-oriented framework that can simplify system software design and implementation by expressing it at a higher level of abstraction. Our work concentrates on how to achieve a higher separation of aspectual components, functional components, and layers from each other. Our goal is to achieve a better design model for implementing system software in terms of modularity, reusability and adaptability.

  • It is an established fact that the university library is an important element in the higher education system. To keep abreast with the changing social environment industrial development and explosive increase of knowledge, the university library must also find new a n.0, pproaches to better serve the users in the university community. Also, on the part of university faculty, instructional methods must be improved from text book oriented education toward assignment oriented education. To facilitate effective teaching, the role of university library and its efficient use has become more important and indispensable. The objective of this study was to review the literature, and to find out current practice among students and professional librarians on the library instruction in order to find ways to strengthen and improve it. A specially designed questionnaire was used to survey current status. Results of the survey are summarized as follows; (1) Most university students received some guidance on library utilization as part of their freshman orientation program. However, it is found that the elementary nature of the guidance program was insufficient for their subsequent actual attempt to use. Students are not familiar with library organization, search procedure, and they lack basic knowledge on library service available to them. (2) Problem areas related to library instruction are insufficient amount of time allocated for the guidance program, big size of orientation program, and lack of interest on the part of students, etc. It is therefore recommended that the above mentioned problem areas be overcome through cooperative and concerted efforts among faculty members, professional librarians, and the university administration by increasing library instruction hours, improving the contents of program in its scope and depth to be practically useful. To sum up, the lecture oriented education should be shifted toward library oriented education by improved instruction program on library use.

  • How the society perceives National Park plays the most important role to achieve the goal for the National Park, which is to protect the ecosystems in the park. The survey for the visitors to Soraksan National Park was conducted to search for the answer to the question. As a result of the analysis based upon the perception types derived from the survey and factors affecting those types, the National Park can be explained by emotionally oriented type(scenic beauty), culturally oriented type, recreation oriented type, and economically oriented type. The first three types are strongly rooted in traditional culture, whereas the fourth type always conflicts with the goal of ecosystem protection. Korea has a long way to go to be familiarized with both the concept of ecosystem protection required by IUCN(The World Conservation Union) and the environmental ethics approach popularly promoted in the western world. The long term strategy for the protection of natural ecosystem should be approached in a manner that the traditional culture can be integrated into all aspects of park management.

  • Toward the development of practical methods for observed data oriented bispectral estimation, an automatic means for determining the smoothing bandwidth of bispectral windows is proposed, that can also provide an associated optimum bispectral estimate of stationary non-Gaussian signals, systematically only from an observed time series datum of finite length. For the conventional non-parametric bispectral estimation, the MSE (mean squared error) of the normalized estimate is reviewed under a certain mixing condition and sufficient data length, mainly from the viewpoint of the inverse relation between its bias and variance with respect to the smoothing bandwidth. Based on the fundamental relation, a systematic method not only for determining the bandwidth, but also for obtaining the optimum bispectral estimate is presented by newly introducing a MSE evaluation index of the estimate only from an observed time series datum of finite length. The effectiveness and fundamental features of the proposed method are illustrated by the basic results of numerical experiments.

  • This study is for the analysis on the basic engineering education for enhancing the quality of engineers at a local engineering school. Negative appraisal for the engineering education by industry, the decrease on the number of students applying for the colleges of engineering, the changes on the high school education make the engineering schools forced to improve the basic engineering education. For the starting point for the study, we have surveyed on the current engineering education by asking questions to professors, students and alumni of Hongik College of Science and Technology. Analyzing the survey results and considering the needs by industry, we have set the basic educational philosophy as educating practical engineers and have decided the goals of basic engineering education as changing to student oriented education, enhancing the field adaptation capability, improving the problem solving ability and introducing engineering design courses.
