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.

측두하악장애 환자에서 저작 효율 및 구강건강관련 삶의 질 평가

이용승,변영섭,최종훈,안형준,Lee, Yong-Seung,Byun, Young-Sub,Choi, Jong-Hoon,Ahn, Hyung-Joon 대한안면통증구강내과학회 2010 Journal of Oral Medicine and Pain Vol.35 No.2

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.

이용승 ( Yong Seung Lee ) 한국민족연구원 2016 민족연구 Vol.0 No.66

2만 9,137명. 2016년 3월 국내 체류 북한이탈주민의 숫자이다. 경제와 안보를 비롯하여 북한 체제가 전반적으로 안정되지 않는 한 북한이탈주민의 숫자는 나날이 늘 것이라는 전망은 대단한 분석을 필요로 하지 않는다. 그러면 우리 사회는 이들을 어떻게 대우하고 있는가? 그들은 어떤 처지에 놓여 있는가? 그 전에 그들은 누구이고, 차별의 작동방식은 어떠한가. 이 글은 북한이탈주민의 남한 사회통합 방안 모색을 위해 위 질문에 답하는 것을 목적으로 한다. 북한이탈주민의 남한 내 위상을 태생적 이중성과 성질상의 이중성으로 규정하고, 남한 사회에서 갖는 그들의 내포를 살펴보았다. 그들 존재가 갖는 함의는 통일과정을 시험하는 리트머스 시험지, 타자로서 열린 민족주의의 맹아, 동아시아 공동체의 가능성을 타진해 보는 잣대, 한반도 역사 비극의 상징, 탈경계 경험의 체화자 등으로 제시했다. 차별의 작동방식으로는 북한에 대한 부정 인식, 저개발 국가를 낮게 보는 시선, 잠재적 불안, 유사성에 따른 역차별, 포용 의무감, 이중적 배제 등을 논의하였고, 이어서 차별이 문제가 되는 이유를 설명했다. 2류 시민 양산, 통일 지향성 축소, 동아시아 담론의 형해화 등이 제시된 이유이다. 대안으로는 남한 주류의 인식을 성찰하는 것이 관건이라는 전제 아래 소수자로서 북한이탈주민 재규정, 용어의 변경, 이물감과 민족주의에 대한 성찰, 약자 보호 시스템의 겸비, 주민권 담론, 정체성 인정 등에 대한 논의를 전개했다. 마지막 결론에서는 우리 사회가 지향할 미래 가치는 ‘품위’라는 관점에서 품위 있는 통합을 위한 몇 가지 시론적 의견을 담았다. 29,137 people. This is the number of residents escaping from North Korea (Bukhan Ital Jumin) who live in South Korea. If the regime of North Korea does not become stable including economy and security, outlook that the number of North Korean defectors will be increased from day to day does not require rigorous analysis. Then, how they are treated in South Korea? What about their situation? Who they are, and how discrimination against them works? This article aims to answer these questions for exploring the way of social integration of North Korean defectors in South Korea. Under the premise that North Korean defectors in South Korean have an inherent duality and duplicity of property, they have an implication of litmus paper that put unification process of the Korean Peninsula to the test, of sprouting of open nationalism as the others, of a compass of sounding out the possibility of East Asian community, of a symbol of the Korea`s tragic history, of embodiment of beyond border experience. The causes of discrimination can include: negative perception to the North Korea, eyes looking down the under developed countries, reverse discrimination arising from similarity, sense of duty for incorporation, dual alienation. Then I explain why the discrimination in question. The reason is that discrimination can produce the second-class citizens, contract the unification directivity, and collapse the meaning of East Asian community. The paper suggests several alternatives on the premise that the reflection of main stream`s perception is key point, which are the redefinition of North Korean defectors as minority, changing in terminology, reflection on nationalism and feeling of irritation, arrangement of the weak protection system in South Korea, discourse of denizenship, and recognition of identity. In conclusion, from an angle that future value which the Korean society must pursue is ‘dignity’, I propose some exploratory opinions for decent social integration.

According to the increase of migrants in Korea, the social and political participation of migrants becomes a very important issue. However participation and political representation of migrants in Korea is structurally restricted. This study analyzes the current situation of political participation of marriage migrants in Korea. Data were collected by questionnaire for marriage migrants living in Daegu and Kyeoung-buk province. Income, age, scholarship. efficacy, opinion for participation, and level of language is a key factor of analysis. Political participation is divided into the general participation to political activities and the participation in elections. Independent factors are classified into the socio-economic, psychological, and relational resources. The thesis finds that factors affecting the participation of electorates which previous researches pointed out influence participation of migrants. Opinion for participation, efficacy, level of Korean language skills, participation In migrants communities, acquisition of nationality have positive influence to political participation. Income, social support, scholarship, occupation, etc. have a low or negative relation to political participation. The study reaches to the conclusion suggesting that the support for Korean language education, activation of migrant communities, and easing of acquisition of nationality

국제이주와 인간안보

이용승(Yong Seung Lee) 고려대학교 일민국제관계연구원 2014 국제관계연구 Vol.19 No.2

이주는 국제정치연구의 적절한 주제인가? 이 글은 국가안보와 인간안보의 관점에서 이주의 주요 단계 및 국면을 살펴봄으로써 이주와 국제정치연구를 연계시켜 보고자 하는 문제의식에서 출발하였다. 사실 이주는 지구화 시대의 핵심 이슈를 차지하고 있지만, 기존의 국제정치 학계는 이주에 큰 관심을 두지 않고 있다. 특히 한국의 경우에는 이와 관련된 연구가 매우 드물다. 이 연구는 이주를 전통적 안보와 최근 안보연구에서 중요성을 인정받고 있는 인간안보의 관점에서 분석하여, 이주가 국제정치연구의 주요한 대상이 될 수 있음을 주장하였다. 이 과정에서 국가는 매개고리로서 기능한다. 이주는 그 각 국면, 즉 출입국, 체류, 통합의 과정에서 모두 국가안보와 긴밀하게 연동되어 있다. 또한 이주는 이주민뿐만 아니라 원주민의 인간안보와도 연관된다. 이주를 인간안보의 관점에서 연구하는 것은 이주와 국제정치연구의 조우를 가능하게 한다. 특히 이주의 안보화는 이주 자체에 대한 부정적 인식을 확산시킬 가능성이 있으나, 인간안보는 국민, 비국민, 비시민을 막론하고 국가 영토 내에 거주하는 모든 사람들을 대상으로 하기 때문에 인권의 향상에 기여할 수 있음을 물론 궁극적으로 국가의 안보 능력을 향상시킬 수 있다. 향후 한국은 이주민이 지속적으로 늘어날 것으로 예상되고, 이로 인해 야기될 수 있는 여러 가지 안보적 사안이 있을 것으로 예측된다. 이러한 측면에서 국제정치연구자들이 이주에 주목하는 것은 한국의 미래 전망에 기여하는 방편이 될 것이다. Is international migration proper subject of international relations? Through inspecting the phrases and stages of migration in the perspective of national security and human security, this article has intent to link migration and international relations. Nevertheless migration has been placed in the core of globalization students of international relations have been had little interest in the topic of migration. Especially in the case of Korea, related studies are very rare. In this paper I analyze international migration in the view point of traditional security and human security that recently has been recognized as important topic in security studies, through which I argue that migration can and must be the subject of the study of international relations. State is the linkage in this process. The respective phrases of migration are closely connected with national security and moreover migration has lots of relevance with human security of migrants as well as natives. Studying the migration from the perspective of human security enables the encounter of migration study with international politics. While the securitization of migration could spread the negative perception of migration, human security intends for non-nationals, non-citizens including nationals and citizens. That will contribute to human rights and to the capability of states to boost national security eventually. Henceforth the migrants or settlers in Korea are going to be increased, which will bring about much of security matter. In this respect, it is necessary for researchers in international relations to pay attention to migration and that could be the way for them to service for the future of Korea.

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.

The aim of this thes is isanalyzing the encounters of cultures in the context of Korea. The Focus of analysis is comparison of Filipinos and Vietnamese who has marred Koreans. Sequence of the paper as follow: Methodology, Concept and Theory, Descriptive analysis, Cross analysis, and Conclusion. By mean of 510 respondents, while Vietnamese marriage migrants prefer the assimilation strategy, marriage migrants of Philippines prefer segregation strategy which is characterized by high maintenance and low accommodation. However, cross analysis shows a different result. Vietnamesea ppear to be distributed to the upper part, because ‘attitude to the accommodation to the Korean culture’ of them is very high. They have the ambivalent tendencies of ‘assimilation’ and ‘integration.’ Meanwhile, ‘marginalization’ and‘separation’ are very rare. ‘Integration’ strategy which is both high in ‘accommodation to mainstream,’ and ‘maintenance of homeland culture’ is the Filipino’s acculturation strategy. However, ‘marginalization’ and ‘separation’ are higher than Vietnamese marriage migrant women. There are differences in acculturation strategies according to nationality or cultures, though they are all defined by ‘marriage migrants.’ The policy of immigrants in Korea must be adjusted by reflection of this reality. For the purpose of desirable integration, Korea has to consider the desires of immigrants and should seek coexistence of the Korean culture and inherent cultures of immigrants.

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.

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.
