The present study aims at investigating the current usage patterns of Korean Standard Records Management System. The Korean Standard Records Management System has been designed and distributed by the National Archives Korea in order to support records management of public agencies. An email survey has been sent to 4 types of public agencies: central government agencies, provincial governments, provincial education offices as well as city and county offices. While all agencies are included in the survey for the first three types, only two provincial districts are selected for city and county offices, Out of 101 email questionnaires sent, 65 are returned(63.73%). The results show the usage patterns of 240 functionalities aligned to 9 main functions: accession from records creators, preservation, appraisal, accession to the national archives, reference management, access and tracking, retrieval and use, system management as well as freedom of information management by public institutions. Since its launch in 2007, the system has been distributed to 707 public agencies as of late 2014. The problem is that there has been no attempt to evaluate the functionalities and usabilities of the system. Only grievances from those agencies implemented the system have never been ceased. The present study is expected to offer the levelled ground for productive discussion between the national archives and the agencies.

The government makes efforts to expand the recycling activities of construction waste soil and to increase the usage of recycled aggregate. Accordingly, it has defined the compulsory usage and quality standard by usage of recycled aggregate. To satisfy these efforts requires both technology to produce recycled aggregate which meets the required quality and companies with the technology. Therefore, it requires to review a current status of facilities at the companies which deal with construction wastes. The companies dealing with construction wastes gradually produce the high quality of recycled aggregate. In particular, companies which has over 3-stage processing system for waste concrete continue to increase and means to remove foreign substances are gradually improved.

As the computing and network technique move rm and spread widly, the usage of multimedia application becomes in general while the usage of text based application becomes low. Especially the application which treats the streaming media such as video or movie, one of multimedia data, holds a majority in the usage of computing. MPEG, one of the typical compression standard of streaming media, provides very high compression ratio so that general users could be close to the streaming media with easy usage. However, the encoding of MPEG requires lots of computing power and time. In the paper, we design and implement a parallel MPEG encoder with MPI in cluster envrionment to reduce the encoding time of MPEG.

The meat consumption per person has continuously increased in recent years. However, the labor force in the domestic livestock industry has decreased due to the declining and ageing population. In order to increase productivity, the government have developed and distributed design standard of livestock houses. Presently, report showed that the adaptation rate of the developed livestock house design standard on the real farm was still low. Thus, this paper aimed to find ways to improve the utilization of the design standard through surveys. The survey was conducted on 650 farms across the country. Analysis of the result showed that in the poultry house, the unawareness of farmers to the design standard was found to be the biggest reason for not using the design standards. On the other hand, in the swine house, the previously built swine houses do not fit with the design standard. From these result, the following recommendations were suggested: 1) promotion and education are needed to enhance usage of design standard; 2) since it is impossible to make a design standard considering all the farm sites, it is important to consider the conditions of various farm site prior to enhancement of the design standard; 3) improvement factors such as reinforcing the ventilation design, reflecting animal welfare, preventing livestock diseases, and enhancing ICT devices can also be promoted.

Objectives : The aim of the study is to explain the general guidelines of the WHO standard acupuncture point locations (APLs). Understanding the general guidelines will enable experts to make the clear use of the standard APL for education, research and practice. Methods : In the beginning of development of the standard APL, experts made general guidelines to draw mutual agreements of the three nations (Korea, China, and Japan) on the standard APL. The guidelines include point locating methods, syntax of descriptive sentences, landmarks on body surface, reference acupuncture points, usage of anatomical terminology, and proportional bone measurements. Results : We found that there are some considerable problems in practical use of the APLs due to the strict application of anatomical terms, even on accessory phrases such as region of body in the sentence of each description. Conclusions : We hope that the study helps readers expand the understanding of the newly developed standard APLs resulting from increased application of acupuncture points. Also, it would be a reference to revise the WHO standard APLs in the future.

The purpose of the study is to investigate the characteristics of the elderly housing preference and spatial usage to plan floor space of the elderly housing by the respondents of the ages 50 to 79. Based on the result of the study, it is suggested that the elderly housing should be located in regards to social environmental factors rather than natural environmental ones. There are differences in preference for the space planning of housing units such as the number of rooms and bathrooms, and floor space depending on income level, so the housing should be differently planned to accept the difference of preference. On the other hand, there is not notable difference in furniture preference for each space. In the characteristics of spatial usage according to behaviors, high-income respondents demonstrate the characteristics of spatial usage in accordance with a western lifestyle. Thus, behaviors such as sleeping, watching TV, resting, reading, conversation, and receiving guests, occur using such things as beds, sofas, and dinning tables. On the other hand low-income respondents show a mixed western and traditional lifestyle. Thus many behaviors are done on the floor of bedroom and livingroom in addition to using furniture such as a sofa and chairs. Therefore, the way of spatial usage has to be reflected in the floor space planning. At least floor space of the provided rooms should be planned to accommodate the behavior of the elderly even though all of the rooms preferred can not be provided.

This paper suggests an e-learning system model, a goal-driven personalized e-learning system, which increase the effectiveness of learning. An e-learning system following this model makes the learner choose the learning goal. The learner's choice would lead learning. Therefore, the system enables a personalized adaptive learning, which will raise the effectiveness of learning. Moreover, this paper proposes a SCORM standard, which modifies SCORM 2004 that has been insufficient to implement the "goal driven personalized e-learning system." We add a data model representing the goal that motivates learning, and propose a standard for statistics on learning objects usage. We propose each standard for contents model and sequencing information model which are parts of "goal driven personalized e-learning system." We also propose that manifest file should be added for the standard for contents model, and the file which represents the information of hierarchical structure and general learning paths should be added for the standard for sequencing information model. As a result, the system could sequence and search learning objects. We proposed an e-learning system and modified SCORM standards by considering the many factors of adaptive learning. We expect that the system enables us to optimally design personalized e-learning system.
