마이크로 셀룰라 네트워크에서 다단계 워킹셋 개념을 이용한 효율적인 위치등록
안요찬 大田大學校 産業技術硏究所 1997 산업기술연구소 論文集 Vol.8 No.2
본 논문에서는 다단계 워킹셋 개념을 이용하여 효율적인 위치등록 방법을 제안한다. 위치영역은 이동국이 최근에 방문한 인접한 셀들의 모임이다. 이러한 관점에서 셀들의 모임을 이동국의 워킹셋이라고 규정하였다. 각 이동국은 자신의 위치영역을 가지고 있으며 각각의 위치영역은 고유의 범위와 크기를 지닌다. 위킹셋의 효율적 운영을 통해 각 이동국이 가지는 위치영역내의 셀의 수를 최소화하고 호호출에 대한 페이징 비용을 감소할 수 있을 뿐만 아니라 많은 통화량을 갖는 개별적인 이동국에 대해 요구되는 셀들을 그룹화하여 하나의 유연한 위치영역으로 관리하므로서 위치등록 갱신비용을 감소시킬 수 있다. 이러한 위치등록 및 갱신 비용을 줄이기 위해 워킹셋의 크기를 결정하는 것이 중요한 문제이다. 제안된 방법은 UPT(Universal Personal Telecommunication)나 FPLMTS(Future Public Land Mobile Telecommunication System)와 같은 새로운 무선통신망 시스템에 효율적으로 적용이 가능할 것으로 생각된다. In this paper, an efficient location registration method using the multi-level walking set concept is proposed. A location area is a group of contiguous cells visited recently by individual mobile station. In this concept, this group of cells define a working set of mobile stations. Each mobile station has its own location area, and each location area has its own outline and size. Through the management of working sets, paging cost for incoming call is decreased by minimizing the number of cells in a mobile station's own location area, and the location update cost of highly activated mobile stations is decreased by grouping all the necessary cells into a single flexible location area. To decrease the paging and the location update cost, decision of working set size is a very important factor. We introduce a method that is an efficient location registration using multi-level working sets. Results of an efficient location updating using multi-level working sets that are applicable to cellular radio systems of the 3rd like UPT and FPLMTS are given.

Perceived Health Status and Health Promoting Behaviors among University Students
Ahn, Yo-Chan,Park, Hyun-Suk,Ra, Gyu-Won The Society of Korean Medicine 2014 대한한의학회지 Vol.35 No.4
Objectives: This study aimed to investigate the relationship among perceived health status, dietary habit and health promoting behaviors of university students. Methods: The subjects were 464 university students. Data were collected by using self-reported questionnaires. The results were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression analysis with the PASW 18.0 program. Results: The mean score of perceived health status was 3.24, dietary habit was 2.85 and health promoting behaviors was 2.24. There were significant differences in perceived health status according to gender, BMI, exercise and stress. There were significant differences in dietary habit according to residence, monthly allowance, drinking alcohol, exercise, sleeping hours and stress. In addition there were significant differences in health promoting behaviors according to gender, residence, BMI, smoking and exercise. Also, perceived health status significantly positively correlated between dietary habit and health promoting behaviors. Conclusions: As the results of multiple regression analysis, the related factors of perceived health status of university students were exercise, stress and spiritual growth factor. Therefore, it is necessary to develop multiple health promoting programs considering characteristics of university students. And various strategies have been developed to increase the physical activity should be run.
고객세분화를 통한 한방병원 고객관계관리 시스템 구축모형
안요찬(Yo Chan Ahn) 한국산업정보학회 2010 한국산업정보학회논문지 Vol.15 No.5
본 논문에서는 현재 대학 한방병원에서 운영하고 있는 통합의료정보시스템의 외래환자 인구학적 정보와 진료기록 정보를 이용하여 고객세분화를 실시하고, 그 결과를 활용하여 외래환자 고객만족도 증진을 위한 고객관계관리 시스템 구축 모형을 제안하였다. 제안된 고객관계관리 시스템 모형은 최선 정보기술과 인프라를 이용하기 보다는 현재 구축된 병원정보시스템의 부분적 수정을 통해 구축이 가능하므로 즉시 실현이 가능한 실용적인 모델이 될 수 있다. 또한 마케팅 전략에 따라 적절한 변수와 세분화 방법을 활용할 경우, 외래환자 고객만족 증진뿐만 아니라 다양한 형태의 마케팅 전략을 지원할 수 있는 고객관계관리 시스템 구축이 가능할 것이다. This paper is proposed that implemental mode1 of customer relationship management system for oriental hospital is designed by customer segmentation using persona1 information and medical record of outpatients in existing integrated medical information system database. Proposed mode1 can be practical model at once, because it can construct by partial modification of existing medical information system without additional information technology and infrastructure. And, if we use the proper variable and method of customer segmentation according to marketing strategy, it can be flexible customer relationship management system not on1y improvement of customer satisfaction but a1so various marketing supports.

안요찬 大田大學校 産業技術硏究所 1994 산업기술연구소 論文集 Vol.1994 No.8
This paper proposes the system, based on the international data security standard to prevent the data modifications caused by illegal operation and mis-operation, which is able to mutually supervise the unwanted data modifications among the users. In the result, the Data Assurance System(DAS), based on the proposed method, is designed and implemented using Cyclic Redundancy Check(CRC) algorithm which is usually used calculate the checksum of data block in the computer and networks. Also, reliability and efficiency of the DAS is increased through the performance test of the system which is implemented for the data correctness.
Pontibacter salisaro sp. nov., Isolated from a Clay Tablet Solar Saltern in Korea
Joung, Yo-Chan,Kim, Han-Eul,Ahn, Tae-Seok,Joh, Ki-Seong 한국미생물학회 2011 The journal of microbiology Vol.49 No.2
A Gram-negative, aerobic, rod-shaped, and red-pigmented bacterial strain, $HMC5104^T$, was isolated from a solar saltern, found in Jeungdo, Republic of Korea ($34^{\circ}$59'47"N $126^{\circ}$10'02"E). The major fatty acids were summed feature 4 (comprising iso-$C_{17:1}$ I and/or anteiso-$C_{17:1}$ B; 37.2%), iso-$C_{15:0}$ (20.4%), and iso-$C_{17:0}$ 3OH (15.3%). The DNA G+C content was 46.0 mol%. The major isoprenoid quinone was menaquinone-7 (MK-7). A phylogenetic tree based on 16S rRNA gene sequences showed that strain $HMC5104^T$ formed a lineage within the genus Pontibacter, and was closely related to Pontibacter korlensis (95.9%), P. roseus (94.9%), and P. actiniarum (94.3%). Similarities to all other Pontibacter species were between 95.9-93.9%. On the basis of the evidence presented in this study, strain $HMC5104^T$ represents a novel species of the genus Pontibacter, for which the name Pontibacter salisaro sp. nov. is proposed. The type strain is $HMC5104^T$ (=KCTC $22712^T$ =NBRC $105731^T$).
