In this study, the objective masticatory efficiency of two groups of temporomandibular disorder patients, pain and sound groups, was compared with that in a normal group using the MAI (mixing ability Index). The subjective chewing ability was evaluated using questionnaires, such as the Food Intake Ability Index (FIA) and Visual Analogue Scale (VAS). The Oral Health Impact Profile (OHIP)-49K of the patients was also examined to measure the oral health-related quality of life. The results were as follows: 1. The MAI, FIA and VAS in the pain group were significantly lower than in the normal and sound groups. This shows that the chewing efficiency of the pain group was lower than the normal and sound groups (P<0.05). However, there was no significant difference between the sound and normal groups. 2. The OHIP-49K for the oral health-related quality of life showed a significant increase in both the pain and sound groups compared with normal group. This means that the oral health-related quality of life was lower in both the pain and sound groups. 3. There was a correlation between the MAI, FIA and VAS (P<0.01) in all subjects (71 persons). The OHIP-49K was associated with the FIA and VAS. 4. There was a correlation between the FIA and VAS (P<0.05) in the sound group but no correlation in the other groups. 5. There was a correlation between the FIA and VAS in all groups. 6. The VAS was increased significantly in the pain group according to the level of pain reduction after treatment (P<0.05). However, there was no significant increase in the MAI, even though there was an improvement in masticatory efficiency. In addition, there was no difference in the FIA and OHIP-49K according to the level of pain reduction after treatment. In this study, it is believed that pain is a main factor decreasing the masticatory efficiency in patients with temporomandibular disorders. Moreover, TMJ sounds decrease the quality of life but do not decrease the masticatory efficiency. Therefore, it is important to control the pain in order to improve the masticatory efficiency in temporomandibular disorder patients. Moreover, managing both pain and sound can improve the quality of life.

소셜 상황 인지를 통한 추천 시스템: MyMovieHistory 사례 연구

이용승,정재은,Lee, Yong-Seung,Jung, Jason J. 한국정보통신학회 2014 한국정보통신학회논문지 Vol.18 No.7

소셜네트워크서비스(SNS)는 사용자들이 자신들의 정보를 가족, 친구, 그리고 소속단체원들과 공유하는 것을 가능케 해 준다. SNS 상의 정보의 양은 기하급수적으로 증가하고 있는 추세다. 특히 페이스북은 연예오락(영화, 음악, TV쇼 등)과 관련된 흥미로운 기능을 채택해 오고 있다. 그러나 페이스북은 사용자들에게 관심 아이템을 추천할 때 필요한 사용자들의 시간, 장소, 소셜 상황 등 상황적 정보는 고려하지 않고 있다. 따라서 이 논문에서 사용자들이 언제, 어디서, 누구와 영화를 보는지 등에 대한 다양한 상황적 정보의 통합에 기반을 둔 영화 추천 접근법을 제안 하고자 한다. 또한 두 명이 함께 영화를 관람하러 갔을 때 동시에 만족할만한 영화 추천 방법을 제안한다. 실험을 위해 사용자들의 영화관람 내용을 기록하고 이에 기반을 두어 적절한 추천 영화를 소개해 줄 수 있는 'MyMovieHistory'라는 페이스북 응용프로그램을 개발하였다. Social networking services (in short, SNS) allow users to share their own data with family, friends, and communities. Since there are many kinds of information that has been uploaded and shared through the SNS, the amount of information on the SNS keeps increasing exponentially. Particularly, Facebook has adopted some interesting features related to entertainment (e.g., movie, music and TV show). However, they do not consider contextual information of users for recommendation (e.g., time, location, and social contexts). Therefore, in this paper, we propose a novel approach for movie recommendation based on the integration of a variety contextual information (i.e., when the users watched the movies, where the users watched the movies, and who watched the movie with them). Thus, we developed a Facebook application (called MyMovieHistory) for recording the movie history of users and recommending relevant movies.

Currently, the critical topic of Korean society is a ‘integration’. The polarization of society – sharp decrease of the middle classes, widening of property disparity, the extreme unbalance of a conglomerates and smallmedium sized enterprises, and the gap between regular employees and the temps, capital and local regions, urban and rural areas, owing to which, psychological polarization of a people–has aggravated a crisis consciousness of the Korean people. The long-and short-term fluctuation of population according to the low birth rate and the ageing that brings the increase of migrants is the key issues in arranging the problems of social integration. This study analyses the integration policy of several countries to deduce the implications for our society, which follows the definition of social integration. United Kingdom and France in Europe, United States and Canada as the traditional immigration countries, and Germany and Japan as the states of jus sanguinis are examined. The focus of analysis is put on the legal and institutional aspects of integration policies for the purpose of the institutional implications for Korean society.

ERP 시스템 구축 프로젝트에서의 경계연결활동이 ERP 시스템 성과에 미치는 영향

이용승(Yong seung Lee),김상훈(Sang hoon Kim) 한국IT서비스학회 2018 한국IT서비스학회지 Vol.17 No.3

The purpose of this study is to empirically analyze the relationships between the Boundary Spanning Activities (BSA) of project team and system performance in ERP system development projects. We could theoretically classify the BSA in the ERP development projects into five categories on the basis of existing studies on the BSA in the research fields of organization theory, new product development, and information systems development. These five categories are ‘Ambassador’ activities, ‘Task-coordinator’ activities, ‘Scout’ activities, ‘Sentry’ activities and ‘Guard’ activities. And the relationship between the implementation level of activities included in each category and the project performance (system usage and users’ satisfaction) was hypothesized with respect to five BSA categories. In order to test the hypotheses, we conducted on/offline survey of the participants who were involved in the ERP system development projects, and received 345 valid responses. The unit of analysis was the project team, and the total number of teams that survey participants belonged to were 103 ones. The Structural Equation Model Analysis using the SMART PLS 3.0 was applied to statistically testing the hypotheses. The results showed that 10 hypotheses among 12 hypotheses could be supported. The theoretical implications of this study can be summarized as following; first, redefining and categorizing the BSA (Boundary Spanning Activities) in the ERP system development projects, secondly, deriving measurement indicators of the implementation level for each BSA category and statistically proving the validity and the reliability of them, and finally, suggesting the theoretical background of expanding the management area of ERP systems development projects. Furthermore, the practical implication of this study is that concrete BSA items which are empirically derived can be utilized as effective guidelines for successfully implementing the BSA in the process of managing the ERP system development projects.

다문화수용성 제고, 왜 그리고 어떻게 해야 하는가?

이용승(Yong-Seung Lee) 대구대학교 다문화사회정책연구소 2016 현대사회와 다문화 Vol.6 No.1

이 연구는 다문화수용성 제고는 왜 그리고 어떻게 해야 하는가를 다루고 있다. 먼저 다문화수용성 증대는 다문화수용성이 다문화정책 구현의 도구로서 의미가 있다는 전제 아래 ‘사실’, ‘당위’, ‘이익’, ‘옳음’의 관점에서 정당화하였다. 네 가지 정당화 논리는 서로 겹치는 것은 물론 상호 규율관계에 있다. 다문화수용성 제고를 위한 대안으로는 담론과 교육, 정책을 제시하였다. 담론으로서는 한국 사회의 이질성, 연구자의 역할, 반다문화주의 논쟁 활용, 주민권/구성원권, 사람을 지칭하는 용어로서 ‘다문화’의 폐지 등의 의견을 개진하였다. 교육 부문에서는 교육과정의 구조 변경과 커리큘럼의 전반적 변경을 말하고, 다문화시민성 함양의 관점에서 시민교육이 수행되어야 함을 지적하였다. 정책으로서는 다문화정책이 야기하는 정책 피로감을 낮추어야 한다는 지적과 함께 정책 대상의 확대, 문화에 대한 온전한 이해 반영, 차별금지법 제정, 정책에 대한 편견 및 차별 영향분석평가 등을 언급하였다. 더 근본적으로는 한국 사회의 약자보호 시스템이 갖추어져야 한다고 주장하였다. This study deals with the reason why and how to raise the multicultural acceptance. On the premise that the enhancement of multicultural acceptance has the instrumental meaning of realization of multicultural policy, the reason for the raising of multicultural acceptance is proposed ‘fact,’ duty or must, interest, justice or correctness. Four logics are mutually overlapping and restrict each other. As the measures for enhancing multicultural acceptance, I suggest the discourse, education and policy. The heterogeneity of the Korean society, the role of researchers, the utilization of anti-multiculturalism, denizenship/membership, and the abolition of ‘multiculture’ that refers to specific people are stated as the discourse. In the education sector, the overall transformation of curriculum structure and civic education for the purpose of cultivation of multicultural citizenship are pointed out. As the policy, the enlargement of objects of policy, reflecting full-fledged understanding of the culture, enactment of anti-discrimination law, prejudice and discrimination impact assessment about all policies and acts are mentioned, which has the ends for the reducing the policy fatigue. More fundamentally, I argue that the protection system for the weak must be equipped for the raising of multicultural acceptance or sensibility.

Korean government has implemented multiculturalism or multicultural policy since mid of 2000, though she is not yet multi-ethnic or multi-cultural society in the light of the West. This study`s purpose is appreciation of Korean governmental multicultural policy in terms of institutions. Because history is short, appraisal may be seen more or less hasty. I think, however, intermediate check is needed. For this paper`s aim, I divided the target of multicultural policy into four categories and analyze each of classes; marriage migrants[chapter 2], migrant workers[chapter 3], permanent residents and naturalized citizens[chapter 4], citizens[chapter 5]. In conclusion, I argued that government-driven multiculturalism is no different from assimilation policy and suggested some ideas for more advanced multicultural policy in each categories. Furthermore, if there were no improvement of migrants` situation of second-class citizens in Korean society, even assimilation policy will be failed. For the sake of that goal, this study contended restoration of ``politics`` in the area of multicultural policy. I hope the research to stimulate a more advanced study.

목적 : 자궁경부암 환자들의 임상병리학적 특성을 살펴보고 이들이 5년 생존율에 미치는 영향을 분석하여 ??인자로서의 효용성을 평가하고자 하였다. 연구 대상 및 방법 : 1994년 11월부터 2000년 1월가지 삼성서울병원 산부인과에서 침윤성 자궁 경부암으로 진단 및 치료를 받은 575명의 환자를 대상으로 의무기록 및 수술 기록을 참조하여 임상병리학적 인자들을 확인하였다. 전체 575명의 환자 중 499명에서 자궁경부 원추절제술을 포함하여 type Ⅰ, Ⅱ, Ⅲ hysterectomy의 수술적 치료가 일차적 치료로 시행되었다. 5년 생존율 분석은 Kaplan-Meier method에 의해 분석하였고 생존 곡선간의 비교는 log-rank test를 이용하였다. 각각의 임상병리학적 인자에 대한 다변량 분석은 Cox proportional hazard model을 이용하였다. 결과 : 환자들의 연령 분포는 26세부터 84세까지 있었으며 40대가 가장 많은 발생 빈도를 차지하였다 (30.7%). FIGO 임상병기별 분포는 Ⅰ기가 76.4%, Ⅱ기가 19.2%, Ⅲ기가 1.9%, Ⅳ기가 1.2%였다. 이 중 FIGO 임상병기가 Ⅰb, Ⅱa인 354명 중에서 325명에서 type Ⅲ 자궁적출술이 시행되었다. 임상병기별 전체 575명의 5년 생존율은 다음과 같다 : 제 Ⅰa기 97.5%, 제Ⅰb 95.5%, 제 Ⅱarl 8.5%, 제 Ⅱbrl 66.8%, 제 Ⅲ/Ⅳ기 42%. 임상병기 Ⅰb, Ⅱa 중에서 Type Ⅲ 자궁적출술을 시행한 환자 중 림프절 전이의 빈도는 Ⅰb기가 10.2%이었고, Ⅱa기가 25.4%로 나타났다. 다변량 분석 결과 FIGO 임상병기와 림파절 전이 여부만이 예후 인자로서의 독립성을 보였다. 결론 : 자궁경부암 환자의 5년 무병 생존율에 영향을 미치는 예후 인자는 임상적 병기와 림프절전이 유무인 것으로 나타났으며 이러한 예후 인자에 따라 치료의 성공을 높이려는 시도가 활발히 있어야 할 것으로 사료된다. Objective : The aim of this study was to investigate the clinicopathologic characteristics of cervical carcinoma and to evaluate the prognostic factors which have an impact on 5-year survival. Patients and Methods : 575 patients with invasive cervical carcinoma treated at Samsung Medical Center from November 1994 to January 2000, for whom the records were retrospectively analyzed, were included in this study. Of the 575 patients, 499 patients were primarily treated by surgery including conization or type Ⅰ, Ⅱ, Ⅲ hysterectomy. Medical records including pathologic reports were reviewed to identify clinicopathologic characteristics. Survival was analyzed by Kaplan-Meier method and log-rank test was used for curve comparison. Cox proportional hazards model was used for multivariate analysis. Results : The age distribution of patients was from 26 to 84 years old, and the peak incidence was in the 5th decade. The International Federation of Gynecology and Obstetrics (FIGO) stage distribution of invasive cervical cancer was 76.4%, 19.2%, 1.9%, 1.2% for stage Ⅰ, Ⅱ, Ⅲ, Ⅳ respectively. Among 354 patients with FIGO stage Ⅰb and Ⅱa, 325 patients were treated by type Ⅲ hysterectomy. The overall 5-year survival of 575 patients was 91.9%, and the 5-year disease-free survival rate (DFSR) according to FIGO stage was as follows : Ⅰa 97.5%, Ⅰb and 25.4% in stage Ⅱa. In multivariate analysis, only FIGO stage and lymph node involvement remained independent prognostic factors. Conclusion : This study showed that clinical stage and lymph node involvement status are identified as independent prognostic factors in the patients with cervical cancer.
