We collected age determination cases which were done at Yonsei university dental hospital, department of oral medicine from 1976 to 1999 to analyze it's tendency among Koreans. We analyzed 435 clients cases which were stored by age estimation program from January 1993 to December 1999. The results are as follows: 1. There were no significant difference in the sexual distribution (male : 52.0%, female : 48.0%) and more than half percent (51%) were 20's and 30's. 2. Among the age determination clients, those who wanted to decrease their age (50.3%) and those who wanted to increase their age (49.7%) shows similar in number. And the former case were predominant in the female clients, but the latter case in the male clients. Also the clients below six years of age were predominant in the former case, but the clients more than sixty were predominant in the latter case. 3. The purposes of age correction showed different distribution for ages: job or employment for 20's and 30's, marriage for 20's, registration for school for below six, welfare and other social services for 50 and older. 4. Age was estimated by Nolla's growth stage for 12 and under, calcification of the second and third molar for 12~20, and for 20 and over, Takei's tooth abrasion model was used. 5. The alleged age was in accordance with the documents and other information given by clients, but in the 20.6% of the estimation cases, the alleged age was discarded. In the results of the analysis of age determination cases in Koreans, many of the cases resulted from our historical turbulence and social distinctiveness, causing an increase in the necessity for age correction in each age group. For more accurate determination for each age group, further studies with Koreans must be done continuously.

The purpose of this study is to evaluate the effect of botulinum toxin type A on masseter muscle atrophy and the extent of masseter muscle affected from the injection site in relation to injection dose, with and without occlusal splint therapy through computed tomographic measurement. 32 volunteers were divided into four groups - group 25U (injection dose of 25 unit), group 25Us (injection dose of 25 unit with occlusal splint), group 35U (injection dose of 35 unit), group 35Us (injection dose of 35 unit with occlusal splint). Each group consisted of 8 people. 3 positions (position 1, 2, 3 - 10mm, 20mm and 40mm from the inferior border of the mandible, respectively) were selected for the evaluation of the masseter muscle change. The following results were obtained. 1. The thickness and the cross-sectional area of the masseter muscle had reduced in all groups except for the right side thickness at position 3 of group 25U and group 25Us, and the right side thickness as well as the left side cross-sectional area at position 3 of group 35Us. In group 35Us, the thickness and the cross-sectional area of the masseter muscle had reduced significantly in all positions (P < 0.05). 2. There was no significant difference in the masseter muscle change between the injection dose of 25unit and that of 35unit. 3. The groups with occlusal splint showed greater reduction of the masseter muscle thickness than the other groups (P < 0.05). From the above results, botulinum toxin type A injection together with occlusal splint therapy in the treatment of masseter muscle hypertrophy would be clinically effective.

CoP(Community of Practice) 활동에 영향을 미치는 조직환경과 동기요인에 관한 연구: CoP 발전단계에 따른 탐색적 연구

장희영 ( He Young Jang ),고일상 ( Il Sang Ko ) (주)엘지씨엔에스(구 LGCNS 엔트루정보기술연구소) 2012 Entrue Journal of Information Technology Vol.11 No.3

CoP는 장기적으로 기업의 경쟁력을 확보하기 위한 원천이며 단기적으로는 기업이 직면한 문제들을 해결하기 위한 전문성을 지닌 집단으로서 가치를 지닌다. 이러한 CoP를 육성하기 위해서 다양한 전략이 수행되고 있으나 그 효과는 노력에 비해 큰 성과를 보이지 못하고 있다. 이 연구에서는 CoP 발전단계를 이해하여 차별화된 발전전략을 수립해야 함을 인식하고, CoP 활동에 영향을 미치는 요인들이 발전단계에 따라 차이를 있음을 검증하였다. 이를 위해 CoP 발전단계에 대한 선행연구결과를 바탕으로 CoP 발전단계를 개발하고, 이 단계에 속하는 집단을 대상으로 실증 연구를 수행하였다. 연구결과 CoP를 통한 지식공유에 영향을 미치는 요인 중 적합한 정보시스템, 리더의 참여, 지각된 위험 그리고 조직환경이 통계적으로 유의한 결과를 보였다. 더불어, 네트워크 활동에 영향을 미치는 요인 중에서는 리더의 참여, 지각된 위험 그리고 조직환경이 CoP 발전단계에 따라 통계적으로 유의한 결과를 가진 것으로 나타났다. CoP is one of the sources for securing the competitiveness of a company in the long-term, while in the short-term it is va-lued as a group that possesses the expertise to solve the problems that the company is directly faced with. Various strategies are carried out to develop CoP, but its effect has failed to show results. This research emphasizes the need to establish a diffe-rentiated development strategy by understanding the levels of maturity of the CoP. And verified the differences according to the maturity model related to the elements influencing CoP activities. For this, based on the results of the prior research, reor-ganizing the maturity levels to enable substantiation, and verified differences by targeting groups belonging to each level. From among the factors affecting knowledge sharing through CoP, this study revealed significantly differences in the areas of appropriate IT, participation of a leader, perceived danger and organizational environment. Also, from the factors affecting networking activities, involvement of a leader, perceived danger and organizational environment were revealed to have signif-icantly differences according to the levels of the maturity model of CoP.

데이터 윤리에 대한 초등학생들의 의식조사 및 교육학습방안에 대한 연구

장희영(Hee young Jang) 한국인공지능윤리학회 2022 인공지능윤리연구 Vol.2 No.-

본 연구는 초등교육에서의 인공지능 윤리교육의 중요성에 대해 언급하며 실제적인 교수학습방안을 제시하기 위해 진행되었다. 머신러닝으로 인해 이전까지와는 다르게 더욱 빠르게 변화해가는 시대에서 인공지능 리터러시의 중요성이 더욱 부각되고 있다. 이에 따라 AI 리터러시의 AI 기술역량과 AI 윤리역량에 대한 적절한 교육이 필요하며, 특히나 AI 윤리에 대한 교육은 AI 기술역량에 비해 인식이나 적절한 교수학습방법이 부족한 실정이다. AI 윤리는 단순히 인터넷 사용자가 지켜야 할 윤리가 아닌, 개발자와 공급자와 사용자와 인공지능 기술 자체도 지켜야 할 윤리이다. ‘윤리’라는 전통적인 규범은 변화하지 않았으나, 시대의 흐름에 따라 이 전통적 규범의 적용이 인공지능에도 적용되어가고 있다. 필자는 그중에서도 데이터, 알고리즘 등에 관련된 도덕적 문제를 연구하고 평가하는 데이터 윤리에 대한 연구를 진행하였다. 전통적인 개념의 윤리를 데이터를 사용하며 발생하는 다양한 결과에 따라 통찰력을 가지고 이를 올바르게 식별해 낼 수 있도록 접목시켜 미래 인재를 육성하고자 한다. 다양한 윤리적 문제에 대한 접근을 통해 앞으로 나타날 문제에 대해 예방하고 해결 방법을 스스로 찾아나갈 수 있는 학습자를 양성하는 것이 이 연구의 목표이다. 이에 따라 교수자는 빠르게 변화하는 사회 속 사례를 통해 변화를 인지하고 이 변화 속에서 어떤 태도를 갖추어야 할지에 대한 통찰력을 기를 수 있는 교수학습방안을 지속적으로 제공하여야 한다. 따라서 학습자에게 적절한 교수학습방안을 제시할 수 있도록 도울 수 있는 지속적인 연구를 목적으로 한다. This study was conducted to discuss the importance of artificial intelligence ethics education in elementary education and to present practical teaching methods regarding this topic. As machine learning is changing more rapidly, It further highlights the importance of artificial intelligence literacy. Appropriate education regarding AI(Artificial Intelligence) literacy's technology and ethics capabilities is deemed required. Unfortunately, education on AI ethics lacks recognition and appropriate teaching methods compared to AI technology capabilities. AI ethics is limited to only users of the Internet, but also relevant for developers, suppliers, users, and the artificial intelligence technology as well. Although the traditional code of ethics has not changed, the application of this traditional code has been integrated to artificial intelligence as times went by. Among them, we conducted research on data ethics, which studies and evaluates ethical issues related to data, algorithms, etc. We intend to foster future talents by combining the ethics of traditional concepts so that they can correctly identify various results generated from the data. The goal of the study is to train learners who can prevent future problems to arise by approaching various ethical problems and finding solutions themselves. Therefore, professors should continue adapting to changes arising from the rapidly changing environment, and develop insight into what attitude they should take in this change.

패션 매장 VMD의 인지차원이 소비자의 감정반응과 구매의도에 미치는 영향

장희영(Jang Hee Young),정효진(Jeong Hyo Jin),김재진(Kim Jae Jin) 한국산업경영학회 2015 경영연구 Vol.30 No.3

본 연구의 목적은 패션 매장 VMD를 인지차원으로 재구성하여 감정반응을 매개로 구매의도에 미치는 영향을 분석함으로써 패션 매장의 경쟁력을 강화할 수 있는 전략적 방안을 제시하고자 한다. 기존 VMD에 대한 선행연구 고찰을 통하여, 패션 매장 VMD의 인지차원을 세 가지(정보 제공성, 심미성, 일상탈출성)로 구성하는 것에 대한 이론적 근거를 확보하였으며, 세 가지 인지차원이 감정반응(즐거움-환기-지배)을 매개로 구매의도에 미치는 영향을 분석하였다. 실증분석 결과를 살펴보면, 패션 매장 VMD의 인지차원 중 일상탈출성은 즐거움, 환기, 지배에 모두 정(+)의 영향을 미치는 것으로 나타났으며, 정보제공성의 경우 지배에 정(+)의 영향을 미치며, 심미성은 환기에만 정(+)의 영향을 미치는 것으로 나타났다. 또한 즐거움과 환기는 지배에 정(+)의 영향을 미쳐 감정반응 간 인과관계가 있는 것으로 나타났다. 이러한 감정반응(즐거움, 환기, 지배)은 구매의도에 정(+)의 영향을 미치는 것으로 나타났다. 특히 소비자로 하여금 일상탈출성을 인지할 수 있도록 패션매장 VMD를 구성한다면 감정반응을 불러일으켜 구매의도를 높일 수 있음을 관찰하였다. 본 연구결과를 바탕으로 이론적 및 실무적 시사점과 한계점을 제안하고자 한다. The purpose of this study is to examine VMD cognition dimensions which consumers can perceive characteries in the show windows presentation and to figure out which VMD cognition dimensions produce effects consumers' purchase intentions with mediating consumers' emotional responses. In addition, this study is to identify causal relationship among pleasure, arousal, dominance emotional leading to consumers' purchase intentions. The VMD cognition dimensions, which are informativeness, aesthetics, and escapist, were derived from previous research based on environmental factors of servicescape. The results show that VMD cognition dimensions have an effect on the purchase intention with mediating the consumer's emotions. The results from causal relationship among consumers' emotion showed that pleasure and arousal had a positive effect on dominance. Consumers' emotions, pleasure, arousal and dominance, evoked by VMD had positive effect on purchase intention. All of informativeness, aesthetics and escapist from show window image had positive effects on dominance feeling. Furthermore, escapist had the strongest effects on dominance among emotional status and dominance has a stronger affect than other emotion on purchase intention. This results provide an effective way to increase purchase intention as a marketing strategy. Visual merchandisers should value aesthetics and escapist dimensions when they plan VMD strategy through show window display so that consumer can feel pleasure, arousal, and dominance. Informativeness, entertainment, escapist also have positive impact on pleasure emotion responses.

가상 능숙도와 네트워크 효과가 SNS(Social Network Service) 지속적 사용의도에 미치는 영향

장희영(Hee-Young Jang),박경자(Kyoung-Ja Park) 한국인터넷전자상거래학회 2012 인터넷전자상거래연구 Vol.12 No.2

Social Network Service(SNS) is being recognized as an important part in our society, individual lives and corporate business aspects, and the influence of SNS is growing explosively as expansion and supply of infrastructures that support mobile environments increase. However, above all, successful SNS requires the understanding of users who are active on the network. This is because even if SNS has many attractive characteristics, its values and usefulness change depending on how users utilize it. Also, values that are perceived through the usage experience become important indicators that predict continuous behaviors of users. Therefore, from the user’s perspective, this study attempted a multi-dimensional approach by reflecting characteristics that come from SNS usages. For users, SNS can be said to be the ‘tool of relation’ for ‘communicating’ online. In other words, for active and continuous usages of SNS, functional understandings of specific technologies such as PC and mobile equipments, as well as applications are required(Media Technology). Also, new relationships are formed in a virtual space, in addition to maintaining relationships(Relational Efficacy) and communication is carried by media on the network, instead of face to face communications with users(Communication Skill). In that context, multi-dimensional concept of ‘Virtual Competence’ was suggested based on related precedent studies. Also, the occurrence of network effects that generally appear in network products and services was verified for SNS as well. The study revealed that virtual competence and network effects have effects on users’ perceived values, and it was verified that perceived values and network effects have significant effects on continuous usage intentions of SNS.
