This retrospective study was to analyze the inferior alveolar nerve and lingual nerve damage after the removal of mandibular third molars. In this questionnaire study, the subjects chosen for this study were 2472 dentists who answered the questionnaire about numbness after the extraction of lower third molars. The data collected by E-mail and web site included the incidence of removal of the lower third molars, the incidence and the experience of numbness of the inferior alveolar nerve and lingual nerve, rate and duration of recovery, the influence in day life after the long-term sensory loss, the period and amount of the indemnity in the case of medical dispute. The results are summarized as follows. 1. The experience rate and the incidence rate of the inferior alveolar nerve numbness by oral surgeons in the past year were 19.9% and 0.14%. Those of the lingual nerve by oral surgeon were 7.7% and 0.05%. 2. The experience rate and the incidence rate of the inferior alveolar nerve numbness by the dentists except oral surgeons in the past year were 9.7% and 0.19%. Those of the lingual nerve by the dentists except oral surgeons were 5.5% and 0.11%. 3. The recovery rate of the inferior alveolar nerve after 1 year and 2 years were 85.6% and 91.3%. The recovery rate of the lingual nerve after 1 year and 2 years were 84.8% and 89.3%. In conclusion, most of numbness may be recovered within 2 years. However the possibility of long term and persistent numbness should not be neglected. Therefore practitioner must inform the possibility of nerve injury and include this possibility in the consent forms.

한성희(Han, Sunghee) 한국소비문화학회 2021 소비문화연구 Vol.24 No.3

본 연구의 목적은 불안정애착유형과 게임중독경향성 사이의 영향관계를 분석하는 것이다. 조사대상은 10-30대 게임이용자로 최종 359부를 분석대상으로 하였다. 연구방법은 SPSS를 이용하여 요인분석, ANOVA, t-test, 다중회귀분석을 실시하였다. 분석결과는 다음과 같다. 첫째, 게임중독경향성은 정서몰입형과 유지몰입형, 저항몰입형 3개의 요인으로 분류되었다. 정서몰입형은 정서적으로 게임에 중독되어 게임을 그만두는 것에 대해 막연한 불안감과 초조감 느끼는 유형이다. 유지몰입형은 게임 하는것에 대한 내성이 생겨 게임을 계속해서 유지하려고 하는 유형이며, 저항몰입형은 게임을 하는 것에 간섭이나 방해를 받으면 오히려 게임을 더하려고 하는 유형이다. 게임중독경향성은 유지, 정서, 저항몰입형 중독경향성 순으로 높게 나타났다. 둘째, 불안정애착유형은 애착회피, 애착불안, 소통회피의 3개의 요인으로 분류되었다. 애착회피는 타인과 친밀감을 형성하는 것을 두려워하여 회피하려는 것이고, 애착불안은 타인과 관계를 맺는 것을 불안해하는 것이다. 소통회피는 타인과 자신의 감정과 이야기를 나누는 소통을 회피하는 유형이다. 불안정애착유형의 정도는 소통회피, 애착회피, 애착불안의 순으로 나타났다. 상위정서인식은 정서개선과 정서명확의 2개의 요인으로 분류되었다. 정서개선은 자신의 정서가 부정적일 때 이를 개선하고자 하는 것이고 정서명확은 자신의 정서상태를 명확하게 인식하는 것에 관한 것이다. 정서명확의 정도가 정서개선 보다 높게 나타났다. 게임 후 감정형성은 후회 및 죄책감과 같은 부정의 감정과 긴장완화와 즐거움을 경험하는 긍정의 감정에 관한 것으로 분류되었다. 게임 후 형성된 감정은 긍정감정이 부정감정보다 높게 나타났다. 셋째, 정서몰입형과 저항몰입형의 게임중독경향성은 여성보다 남성이 높게 나타났고 자유소비지출액이 많을수록, 애착회피와 애착불안이 높을수록, 소통회피의 경우에는 낮을수록, 게임중독경향성이 높게 나타났다. 정서개선의 영향력은 정서몰입형과 저항몰입형에 대해서만 정적인 유의미성을 보였다. 즉, 정서개선의 정도가 높을수록 정서몰입형과 저항몰입형의 중독경향성이 높게 나타났다. The purpose of this study is to analyze the effect of different types of insecure attachments on video game addiction tendencies. To that end, 359 consumers in their 10’s to 30’s were analyzed through a factor analysis, an analysis of variance (ANOVA), a T-test, and a multiple regression analysis using SPSS. The findings are as follows. First, video game addiction tendencies were classified into three types: the emotional commitment type, the continuance commitment type, and the resistant commitment type. People falling under the emotional commitment type are emotionally addicted to video games, and experience vague anxiety and insecurity about stop playing them. The continuance commitment type refers to people who try to continue to play video games on account of their high tolerance. People of the resistant commitment type respond to intervention or disruption by playing games more. The mean value is the highest for the continuance commitment type, followed by the emotional commitment type and the resistant commitment type. Second, insecure attachment was grouped into three categories: attachment insecurity, attachment avoidance, and communication avoidance. People with attachment insecurity are afraid of, and try to avoid, forming intimate relationship with others. People in the second are anxious about forming relationship with others. Communication avoidance refers to avoiding to share feelings and conversations with others. The degree of insecure attachment was the highest with communication avoidance, followed by attachment avoidance and attachment insecurity. Higher-order emotional cognition consisted of two factors: emotional improvement and emotional clarity Emotional improvement refers to trying to improve negative emotions, and emotional clarity is about clear awareness of one’s emotional state. The level of emotional clarity was found to be higher than emotional improvement. Emotions felt after playing games consisted of negative emotions such as regret and guilt, as well as positive emotions such as decreased tension and feeling of comfort and enjoyment. Among post-gaming emotions, positive emotions were found to be higher than negative emotions. Third, game addiction tendencies of the emotion commitment type and the resistant commitment type were found to be higher among men than women. A higher level of spending on discretionary consumption, and a higher level of attachment avoidance or anxiety was correlated with a high level of game addiction tendencies. A higher level of communication avoidance was linked with a higher level of game addiction tendencies. The effect of emotional improvement was positively significant only for the emotion commitment and resistant commitment types. In other words, a person with a higher level of emotional improvement reports higher addiction tendencies of the emotional commitment type and the resistant commitment type.

This study analyzed the consumer behavior and satisfaction towards hybrid cars. This study targeted 387 consumers who actually drive hybrid cars, and it analyzed the consumers’ perceived cost and consumption value of cars on their satisfaction. The findings of the analysis are summarized below. Firstly, the consumption values experienced by consumers using hybrid cars were categorized into the following three types: economic value, social value, and symbol of distinction value. The economic value recorded the highest score, while the score of the symbol of distinction value was the lowest. The perceived cost of hybrid car consumers consisted of the following two types: pre-purchase exploration cost and after-purchase adaptation cost. The pre-purchase perceived cost of hybrid cars was found to be fairly high, and the after-purchase adaptation cost recorded a lower score. Secondly, the factors that showed a high influence on consumption satisfaction were the consumption value of distinction and symbol.

한성희(Sunghee Han),정종필(Jongpil Jeong) 한국통신학회 2013 韓國通信學會論文誌 Vol.38 No.4C

본 논문에서는 i-FP(intelligent Fast PMIPv6)로 명명한 새로운 이동성관리 네트워크 기법을 제안한다. i-FP는 지역 이동성관리 문제를 해결하기 위해 고안했다. 하나의 도메인 내에서 MN(Mobile Node)을 다른 네트워크로 이동이 가능하게 하기 위해 i-FP에서는 PMIPv6(Proxy Mobile IPv6)의 세가지 네트워크 엔티티인 LMA(Local Mobility Anchor), MAG(Mobile Access Gateway), MN의 개념을 확장하여 기능을 추가했다. 세가지 네트워크 엔티티로 i-FP에서는 MN의 핸드오버 지연 시간을 감소시키고 IP 헤더 스와핑 메카니즘을 사용하여 트래픽 오버헤드를 회피하여 네트워크 처리량을 증가 시킨다. i-FP의 성능을 평가하기 위해, 새롭게 제안하는 i-FP와 같은 로컬 이동성 관리 프로토콜인 HMIPv6(Hierarchical Mobile IPv6), PMIPv6까지 이상 총 세가지 기법으로 다양한 기준을 사용하여 네트워크 기법의 성능을 측정 / 평가하였다. 성능평가 결과를 종합해서 i-FP가 트래픽 오버헤드가 없어지고 다른 비교 기법 대비 평균 라우팅 홉수 10.2%, 트래픽 시그널링 비용 58.5%, 핸드오버 지연은 16.3% 감소의 성능향상이 일어남을 보여준다. In this paper, we propose a new mobility management scheme, called i-FP(intelligent Fast PMIPv6). Our proposed i-FP scheme is addressed for solving the existing local mobility management problems from legacy frameworks. To move MN(Mobile Node) to other networks in one domain, i-FP employs three network entities which are extended from PMIPv6(Proxy Mobile IPv6), LMA(Local Mobility Anchor), MAG(Mobile Access Gateway) and MN. In i-FP, the three network entities can reduce the handover delay time of MNs. Also, i-FP uses an IP header swapping mechanism to avoid the traffic overhead and improve the throughput of network. To evaluate the performance of i-FP, we analyze our i-FP, HMIPv6(Hierarchical Mobile IPv6) and PMIPv6 which are legacy protocols of local mobility management in terms of various parameters. Finally, our i-FP scheme shows good performance(reduction of routing hops 10.2%, signaling costs 58.5% and handover delay 16.3%) than other network schemes for the total cost.

Collaborative filtering(CF) for the personalized recommendation is a successful and popular method in recommender systems. But the mainly researched and implemented cases focus on dealing with independent items with explicit feedback by users. For the domain of TV program recommendation in VOD service platform, we need to consider the unique characteristic and constraints of the domain. In this paper, we studied on the way to convert the viewing history of each TV program episodes to the TV program preference by considering the series structure of TV program. The former is implicit for personalized preference, but the latter tells quite explicitly about the persistent preference. Collaborative filtering is done by the unit of series while data gathering and final recommendation is done by the unit of episodes. As a result, we modified CF to make it more suitable for the domain of TV program VOD recommendation. Our experimental study shows that it is more precise in performance, yet more compact in calculation compared to the plain CF approaches. It can be combined with other existing CF techniques as an algorithm module.

최근 Wi-Fi 기능이 내장된 휴대용 장비가 제공하는 다양한 자료와 멀티미디어 서비스가 점점 늘어나고 있으며, 어디서든 인터넷에 접속하려는 전반적인 요구가 급격히 증가하고 있다. 이에 따라 네트워크에 많은 비용 부담이 증가하고 있다. 따라서, 모바일 네트워킹에 관한 최근의 연구 중 에너지 효율적인 네트워크 이동성 기술은 큰 주목을 받고 있다. 네트워크 이동성 환경에서 비용 효율적인 프로토콜 설계는 이동성 시그널링과 패킷 전달, 그리고 비용 효율성의 중요한 이슈 중의 하나인 유, 무선에서 제한된 네트워크 대역폭을 절약하여 불필요한 비용을 감소시키는 것이다. 본 연구에서는 기존의 네트워크 이동성 기법에 멀티캐스팅을 지원하는 고속 핸드오버, 효율적인 도메인간 이동성 관리와 패킷전달 메소드를 제공하는 비용 효율적인 기법을 제안한다. 본 논문에서는 위치 갱신 비용과 패킷 터널링 비용을 합한 총 비용의 관점으로 기존의 NEMO 기법인 N-PMIPv6, rNEMO, PR-NEMO의 성능과 새롭게 제안하는 Fast PR-NEMO의 성능을 비교 분석하고, 제안된 기법이 기존제안된 기법들에 비해 총 비용이 낮은 가장 에너지 효율적인 방식임을 증명한다. In recent years, there are many data and multimedia services that are supported by WiFi-enabled mobile devices. As a result, the demand for the ability to connect to the Internet anywhere is rapidly increasing and network infrastructure is becoming increasingly important. The design of cost-efficient network mobility (NEMO) protocol is intended to reduce the demand for limited wired / wireless network bandwidth at the signaling of mobility support and packet delivery operations. In this paper, we propose a cost-effective inter-LMA domain mobility management scheme which provides fast handover with multicasting support in NEMO environments. And our Fast PR-NEMO scheme is compared with N-PMIPv6, rNEMO, and PR-NEMO. In conclusion, our proposed scheme shows the best performance in terms of location updating cost, and packet tunneling cost.

Recently the change of content consumption trend activated the social video sharing platform and the video clip itself. There have been intensive interests and efforts to automatically abstract compact and meaningful video clips. In this paper, we propose a method which use the clustering of the bookmark data created by collective intelligence instead of using the video content analysis. The partitional clustering of points in 2-dimensional space derived from the bookmark data make it possible to abstract highlights effectively. The method is enhanced by the 1-dimensional accumulated bookmark count graph. Experiments on the real data from KBS internet service show the effectiveness of the proposed method.
