  • 이 연구는 미국 캘리포니아 주 샌프란시스코 공공도서관이 주관하는 'One Book' 지역사회 독서운동인 'One City One Book: San Francisco Reads' (이하 OCOB라 부름)의 사례연구로 진행하며, 2005년부터 2024년까지 추진한 목표, 선정 책들의 특성 및 주요 행사와 활동을 분석하였다. 분석 결과를 보면, OCOB는 전도시를 북클럽으로 만들어 독서와 토론을 촉진하는 전형적 'One Book'의 목표를 지향하면서, 샌프란시스코의 도시 정체성을 중심으로 문화적 및 인종적 다양성을 반영한 책들을 선정하였다. 시민들은 적극적 프로그램 참여 및 선정 책 대출 증대 등으로 반응하였다. OCOB는 다양성의 이해 및 지역사회 통합을 지향하는 'One Book' 독서운동으로서의 지속성, 일관성, 자율성 및 독립성을 보여주며, SFPL의 '비전 2030'을 위한 '문화적 확장자' 및 '커뮤니티 촉매자' 전략의 일환으로 향후에도 추진될 것으로 전망된다.

  • 최단 경로 탐색 알고리즘 (Shortest Path Algorithm)은 출발지에서 목적지에 이르는 여러 경로 중에서 가장 경제적이고 효율적인 경로를 찾는 알고리즘으로 레이블링 기법에 기초하고 있다. 레이블링 기법에는 레이블 고정(Label-Setting) 기법과 레이블 수정 (Label-Correcting) 기법이 있다. One-to-One 최단 경로 탐색 알고리즘에서 레이블 고정 기법이 빠르다고 알려져 왔으나 최근 연구에서 대용량 도로 데이터에 대한 실험을 통해 레이블 수정이 레이블 고정보다 탐색 씨간이 빠름을 보였다[1,2]. 레이블 수정 기법 중에서 가장 속도가 빠른 것은 그래프 성장 (Graph Growth) 알고리즘인데, 이 알고리즘은 One-to-All 방식을 사용하고 있으므로 One-to-One 최단 경로 탐색에는 적합하지 않다. 본 논문에서는 One-to-One 방식을 사용하는 새로운 알고리즘을 제안하였고, 실험결과 그래프 성장 알고리즘의 성능에 비해 새로 제안된 알고리즘의 성능이 30~40 향상되었음을 알 수 있었다.

  • one-way 함수는 패스워드와 같이 compute는 쉽고 invert는 어렵다는 의미를 갖는 함수로서 암호기법에서 매우 중요한 역할을 하고 있으며, 특히 encryption schemes 의 존재성은 바로 one-way 함수의 존재성을 필요로 하고 있음은 잘 알려진 사실이다. 본 연구에서는 기존 암호기 법에 존재하는 one-way 함수들을 분석하고 또한 one-way 함수가 될 수 있는 여러 가지 형태의 함수들을 조사 연구함으로써 다양하고 안전한 encryption schemes을 갖추기 위한 근원을 제공한다. one-way 함수의 종류, 역할과 그 특성을 살펴보고 one-way 함수의 일반적인 조건을 통하여 one-way 함수가 될 수 있는 여러 가지 함수들을 조사하고, one-way 함수와 trapdoor 함수에 대한 이론적 특성을 논하였다.

  • In Korean traditional architecture, the Gong-po style is divided into the Jusimpo, Dapo and Ikgong. Jusimpo and Chulmok-Ikong, where only Gong-po is placed on the column, differ in form of Gong-po depending on the viewpoint. Since 'Chulmok-Ikgong' has been generally regarded as 'One Chulmok-Two Ikgong', the precedent researches have been conducted mainly on 'One Chulmok-Two Ikgong' in the Gong-po style classification. However, when it comes to 'One Chulmok', the style of Ikgong can be organized from the one to three steps and this study is particularly for examining the occurrence and transformation of 'One Chulmok-One Ikgong'. One of the case study sites, Bonghwa Cheongamjeong was originally built in the 16th century, and is believed to have been repaired from 'Non Chulmok-One Ikgong' to 'One Chulmok-One Ikgong'. Since the beam linked directly to the upper part of a capital, it does not connect the eave trave(architrave) in between. Also, Soro which supports Jangyeo(the architrave strip) has been placed and linked in comparatively lower position. It is confirmed by the signigicant difference in the hierarchy of Gong-po forms in one architecture. The Jeonju-Hyanggyo Daeseongjeon, which was built in the 17th century among the subjects, was similar with 'One Chulmok-One Ikgong', but it was found to be the type of Jusimpo form because the bottom of the beam and the top of the Ikong are apart. And Gongan is confirmed at Cheomcha. In the 17th century, it can be seen that Heot-Cheomcha disappeared and Ikgong was started to use as a constant figure. The end of the 18th century, it can be seen that it was changed into a ornament added on Haeng-gong, being seen in the case of Hwaseong Dongjangdae. In conclusion, it can be seen that 'One Chulmok-One Ikgong' were developed in both the Jusimpo and Ikong style. The transformation into 'One Chulmok-One Ikgong' was inevitable consequence related with an elevation difference between the eave trave and the column trave.

  • Recently, one-person households have surpassed nuclear families. One-person households are expected to have many problems with health due to an irregular life style and a tendency to be more isolated from society. In addition, we need to divide the generations and survey each generation due to differences in one-person household factors and characteristics as well as the unique physical conditions of each generation. Therefore, based on the sixth Korea National Health and Nutrition Examination Survey, this survey examined health behavior differences between one-person households and non-one-person households according to generation (respectively) as well as studied how one-person households and health behavior influence subjective health conditions. The major result of this survey is as follows. First, one-person households reveal a higher rate in the negative health behavior than non-one-person households. Second, the physical activity of all households reveals a high rate of non-activity. Third, health scores of one-person households are lower than that of non-one-person households; consequently, the analysis of health scores for one-person households and non-one-person households indicated that the middle age health scores for one-person households have been lowest in generations. Fourth, the factors that influence subjective health conditions indicated that one-person household and health behavior has meaningful influence; in addition, the subjective health condition of one-person households are lower than non-one-person households under controlled health behavior.

  • The cantilever beam with nonlinearity has many dynamic characteristics of nonlinear vibration. Nonlinear terms of a flexible cantilever beam include inertia, spring, damping, and warping. When the beam is given basic harmonic excitation, it shows planar and nonplanar vibrations due to one-to-one resonance. And when the one-to-one resonance occurs, the flexible beam shows different behaviors in those vibrations. For the one-to-one resonance occurring in each mode, the phase value of the planar vibration is different from that of the nonlinear vibration. This paper investigates the phase change and the phase difference between such planar and nonplanar vibrations which are caused by one-to-one resonance.

  • Objectives: The aim of this study was to investigate the effect of glide path preparation with PathFile and ProGlider nickel-titanium (NiTi) files on the cyclic fatigue resistance of WaveOne NiTi files. Materials and Methods: Forty-four WaveOne Primary files were used and divided into four groups (n = 11). In the first group (0 WaveOne), the WaveOne Primary files served as a control group and were not used on acrylic blocks. In the 1 WaveOne Group, acrylic blocks were prepared using only WaveOne Primary files, and in the PF+WaveOne group and PG+WaveOne groups, acrylic blocks were first prepared with PathFile or ProGlider NiTi files, respectively, followed by the use of WaveOne Primary files. All the WaveOne Primary files were then subjected to cyclic fatigue testing. The number of cycles to failure was calculated and the data were statistically analyzed using one-way analysis of variance (ANOVA) and the Tukey honest significant difference multiple-comparison test at a 5% significance level. Results: The highest number of cycles to failure was found in the control group, and the lowest numbers were found in the 1 WaveOne group and the PF+WaveOne group. Significant differences were found among the 1 WaveOne, PF+WaveOne, and control groups (p < 0.05). No statistically significant differences were found between the PG+WaveOne group and the other three groups (p > 0.05). Conclusion: Glide path preparation with NiTi rotary files did not affect the cyclic fatigue resistance of WaveOne Primary files used on acrylic blocks.

  • Wide-spread practitioner literature exists for the one-to-one marketing effect from a firm's perspective; however, limited research discusses the psychological effect of one-to-one marketing from a consumer's perspective. The authors test a model that integrates the level of consumer-perceived one-to-one marketing effort (OTO-E), instrumental (i.e., perceived usefulness) and affective benefits (Le., pleasure and arousal), and attitude toward the e-store (ATE). The analysis of an online survey (conducted with 195 U.S. undergraduates) confirms the positive effect of level of OTO-E on the benefits that influence ATE. In addition, it reveals the positive effect of the affective benefits on the instrumental benefit. The results expand the current research on the value of one-to-one marketing by presenting a consumer-oriented approach. As the study was conducted in the U.S. market with intense consumer demands for individuation of service, the results should provide useful managerial/ theoretical implications to Korean apparel e-tailers, concerning their future implementation of one-to-one marketing.
