When we make treatment plan of class III malocclusion children, it is difficult to determine whether we treat it with orthognathic surgery or without orthognathic surgery. To determine that, we must consider many factors, such as cephalometric analysis, growth pattern, family history, and skeletal age. A Harvold cephalometric analysis is useful in determining the amount of discrepancy by comparing the maxillary unit length with mandibular unit length. We tried this study to help the decision of treatment planning in class III malocclusion children by comparison in class III malocclusion and normal occlusion children using a Harvold analysis. Materials and Methods: The materials for this study consisted of 20 class III malocclusion children. Cephalometric tracing and measurements were performed by one investigator. The control group consisted of 18 normal occlusion children and lateral cephalograms were obtained from 8.5 to 14.5 years old children biannually. The relationships between class III malocclusion group and normal occlusion group were evaluated statistically. Results: The lower anterior facial heights between two groups were not significantly different, although the lower anterior facial heights of class III malocclusion group was higher than those of normal occlusion group in all age groups. The Maxillary-mandibular unit length differences of class III malocclusion group were significantly higher than those of normal occlusion group(p <0.05). Conclusion: A Harvold analysis was useful to make treatment planning for class III malocclusion children.

Polydactyly is a most common congenital anomaly of the foot. As is in the hand, it's classification systems and operative methods are various and complicated, but not much attention is given. We reviewed 129 foot polydactylies of 96 patients since the last 10 years(1993- 2003). Cases were classified morphologically and radiologically by previous classification systems(Wassel's classification, Hirase's classification) and then operative methods, complications, residual deformities were reviewed. Cases from the complications related to surgery including residual deformities were the major concern and 20 cases of unfavorable results were mainly due to varus deformity and metatarsal bone status. Based on our study, cases were reclassified by metatarsal bone status and varus deformity, and in conclusion we found that the new classification system is more helpful in deciding surgical method, predicting complications and residual deformities. Therefore, we suggested a new simple classification system based on the status of metatarsal bone and varus deformity, which is a more suitable system to planning operative method and predicting complication and residual deformity than the previous classification system.

In this study, different cultural groups of Oriental and Western people as the survey object, and the use of shared accommodation service experience difference comparative study. Combine literature survey and questionnaire in the research process. We collect service evaluation factors through a literature survey and survey the extraction of service evaluation factors and evaluation of service experience through a questionnaire. Starting from the sharing economy, this paper sorts out the development status of shared accommodation service and analyzes the problems that occur when westerners use public services. Secondly, in the preliminary study, the evaluation elements and use process of shared accommodation service are sorted out and demonstrated. Finally, based on the thinking style, importance perception, and service use experience of the Eastern and western people in the process of using shared accommodation service, the experience differences are found and summarized. The results of the study showed that in the different service stages of thinking (search service stage and service experience stage), Westerners think more rationally compared to Easterners. In the analysis of perceived importance, Westerners perceived the appointment stage and the service experience stage as more important in the complete service experience compared to Easterners.In the analysis of user experience, there are significant differences between Easterners and Westerners in the simplicity, beauty, and ease of the pre-search service stage, simplicity, beauty, convenience and ease of reservation service stage, convenience, care, and uniqueness of service experience stage, and convenience, care, uniqueness, and ease of evaluation feedback stage. In the evaluation elements where differences were found, the mean values for Easterners were significantly larger than those for Westerners, implying that Westerners had a poorer service experience compared to Easterners. Through empirical analysis, it promotes enterprises to better understand the use experience of customers of different cultures, helps enterprises to continuously optimize their services according to the differences in customer experience, improves customer satisfaction, promotes better development of enterprises, and develops short-term lodging industry.

Background The rapid development of public electric bicycle industry provides solutions to problems such as green travel and last mile, and also alleviates urban traffic congestion to a certain extent. In the sharing economy, foreigners are also important users. But when foreigners use shared services, they often encounter more problems. For example, the process of registering an account is too cumbersome, and it takes longer to find services than native people. Many services are designed for native people, which often does not conform to the usage habits of foreigners. Therefore, foreigners often face more difficulties in using public services than native nationals. Methods This study makes a comparative study on the public bicycles provided by Korea and China, which are distinguished by native and foreigner. In the process of research, literature investigation, interview and questionnaire survey go hand in hand. Firstly, starting from the sharing economy, this paper combs the development history, operation status and use status of public electric bicycles, and analyzes the problems existing in foreigners using public services. Secondly, in the discussion of the first study, combing the evaluation elements and use procedures of public electric bicycle service, and conducted an empirical study. Finally, according to the service problems encountered by domestic and foreign consumers in the process of using public electric bicycles, the problems existing in different use stages are compared, and the improvement schemes are put forward. Results Natives and foreigners show differences in usefulness and responsiveness in satisfaction factors, and differences in convenience and ease of use in convenience factors. Reliability performance difference in safety factors, comfort and interest performance difference in comfort factors. Conclusion This study puts forward suggestions for enterprises to improve management and service from four aspects: satisfaction factors, convenience factors, safety factors and comfort factors. Through empirical analysis, this study promotes enterprises to better understand the real feelings of customers in the process of using services. Enterprises constantly optimize services according to the differences in customer experience, better meet customer needs and improve customer satisfaction, thus helping the public electric bicycle industry to develop better. In addition, most sharing economy has the characteristics of economic and environmental protection, and this study can also provide reference for other sharing economy industries.

원자력 발전소 규제제도 개선을 위한 법률적 검토 - 원자력안전위원회와 원자력안전법을 중심으로 -

The earthquake of 5.8 magnitude that occurred in Gyeongju in September, 2016 informed that our country is no longer an earthquake-free area. The Kori nuclear power plant in Gyeongju has 10 nuclear power plants in operation, and over 3.8million people live near the Kori. If a large earthquake occurs and the nuclear power plant collapses, it will be a disaster because a huge loss of life is expected. Therefore, regulatory measures for safety are essential to sustain nuclear power generation. In Korea, there are seven laws that represent the safety of nuclear power plants, including the Nuclear Safety Act, all of which are under the control of the Nuclear Safety and Security Commission.(NSSC, 원자력위원회) In this paper, I examine whether the NSSC, which enforces most of the regulations set forth by the Nuclear Safety Law, is operating normally. First, I explain the regulations in the Nuclear Safety Act and analyze what role the Nuclear Safety Commission plays in its contents. Next, I analyzed the characteristics of the nuclear regulatory agencies in the US, Canada, France, and Japan through comparative legal methods and examined implications for Korea. This analysis led to the finding that proper regulation could be achieved if the human and material independence of the nuclear regulatory commission was secured. In addition, through the disclosure of information and participation at the civil society level, transparent regulatory activities of nuclear regulatory agencies have become possible, and local residents near the nuclear power plant can also increase the credibility of nuclear power plants. Finally, based on the above analysis, I have listed the problems of the NSSC and examined legislative and policy complementary measures to overcome them. I discussed the necessity and method of human construction of the NSSC which is independent from politics and interests. I also discussed the manpower problem and the budget problem of the Nuclear Safety Commission and the complementary measures of the problem. Furthermore, the issue of information disclosure and the involvement of local residents was also discussed.

중국 네티즌의 가상 아이돌 콘텐츠 구독의도에 관한 연구

손우,박상수,왕서혜 한국외국어대학교 중국연구소 2024 中國硏究 Vol.99 No.0

본 연구에서는 가상 아이돌에 대한 중국 네티즌들의 구독의도를 살펴보기 위하여 가상 아이돌 특성(진정성, 의인성, 통제성, 준사회적 상호작용), 네티즌 특성(사회성, 자아 일치성), 몰입, 구독의도 등에 대해 살펴보았다. 아울러 ACG(애니메이션, 만화, 게임)선호도에 따른 조절효과에 대해 살펴보았다. 분석결과를 토대로 본 연구에 대한 시사점을 도출하면 다음과 같다. 첫째, 구조모형의 경로분석(가설1~5). <가설 1, 2>의 경우, 가상 아이돌 특성(진정성, 의인성, 통제성, 준사회적 상호작용)과 네티즌 특성(사회성, 자아 일치성) 요인 모두 몰입에 정(+)의 영향을 미치는 것으로 나타났다. 특히 가상 아이돌 특성 중에서는 ‘준사회적 상호작용’이, 네티즌 특성 중에서는 ‘자아 일치성’이 가장 크게 영향을 미치는 것으로 나타났다. 따라서 가상 아이돌 관련 콘텐츠에 대한 몰입은 가상 아이돌에 대해 느끼는 친근감이나 호감 그리고 가상 아이돌을 자신이 표현하고자 하는 이미지와 동일시 함으로써 대리만족(vicarious pleasure)을 느낄 수 있는 ‘자아 일치성’이 주요 요인임을 확인하였다. <가설 3, 4>의 경우, ‘가상 아이돌 특성’ 요인 중에서 ‘진정성’과 ‘통제성’ 만이 구독의도에 정(+)의 영향을 미치는 것으로 나타났으며, ‘네티즌 특성’ 요인 중에서는 자아 일치성만이 구독의도에 정(+)의 영향을 미치는 것으로 나타났다. 특히 몰입에서와 마찬가지로 ‘자아 일치성’은 구독의도에서도 가장 크게 영향을 미치는 것으로 나타났다. 따라서 구독의도에 있어서는 가상 아이돌의 말과 행동에 대한 신뢰 즉 ‘진정성’과 ‘인간적 오류(스캔들, 문제행동 등)'의 위험을 최소화할 수 있는 ‘통제성’이, 그리고 몰입에서와 마찬가지로 대리만족을 이끌어 내는 ‘자아 일치성’이 특히 주요 요인임을 재확인하였다. <가설 5>의 경우, 가상 아이돌에 대한 ‘몰입’은 ‘구독의도’에 정(+)의 영향을 미치는 것으로 나타났다. 즉, 가상 아이돌에 대한 몰입이 클수록 관련 콘텐츠를 구독하려는 의도 역시 높아져, 기존 선행연구의 연구결과들과 차이가 없는 것으로 나타났다. 둘째, ACG선호도의 조절효과 검증(가설 6~7). <가설 6>의 경우, ‘가상 아이돌 특성(진정성, 의인성, 통제성, 준사회적 상호작용)’ 요인 중에서는 ‘통제성’과 ‘준사회적 상호작용’에서 조절효과가 있는 것으로 나타났다. 즉, ACG선호도가 낮은(저) 집단에서 높은 집단(고) 보다 ‘통제성’과 ‘준사회적 상호작용’은 몰입에 더 크게 영향을 미치는 것으로 나타났다. 한편, <가설 7>의 경우, ACG 선호도는 몰입과 구매의도 사이 조절효과가 없는 것으로 나타났다. 즉, 네티즌의 ACG 선호도에 관계없이 몰입에 따른 구매의도에는 큰 차이가 없는 것으로 나타났다. The purpose of this study is to examine relationship between variables that virtual idol characteristics (authenticity, anthropomorphism, control, quasi-social interaction) and netizen characteristics (sociability, self-congruity), immersion(flow), and subscription intentions. We also examined the moderating effect of ACG (Anime, Manga(cartoon), and Games) preference. The results were as follows. First, path analysis of the structural model (Hypotheses 1 to 5). In the case of <Hypotheses 1 and 2>, both virtual idol characteristics (authenticity, anthropomorphism, control, quasi-social interaction) and netizen characteristics (sociability, self-congruity) were found to have a positive influence on immersion(flow). In particular, ‘Quasi-social interactio’ was found to have the greatest influence among virtual idol characteristics, and ‘self-congruity’ among netizen characteristics. Therefore, it has been confirmed that the main factors for immersion in content related to virtual idols are the familiarity or liking felt toward virtual idols and 'self-congruity', which allows one to feel vicarious pleasure. In the case of <Hypotheses 3 and 4>, among the ‘virtual idol characteristics’ factors, only ‘authenticity’ and ‘controllability’ were found to have a positive (+) influence on subscription intention. Among the ‘netizen characteristic’ factors, only self-congruity was found to have a positive influence on subscription intention. In particular, as with immersion, ‘self-congruity’ was found to have the greatest influence on subscription intention. In the case of <Hypothesis 5>, ‘immersion’ into virtual idols was found to have a positive (+) effect on ‘subscription intention’. In other words, the greater the immersion in virtual idols, the higher the intention to subscribe to related content, showing no difference from the results of existing previous studies. Second, verification of the moderating effect of ACG preference (Hypotheses 6-7). In the case of <Hypothesis 6>, among the ‘virtual idol characteristics factors, ‘control’ and ‘quasi-social interaction’ were found to have a moderating effect. In other words, in the group with low ACG preference (low), ‘control’ and ‘parasocial interaction’ were found to have a greater influence on immersion than in the group with high ACG preference (high). Meanwhile, in the case of <Hypothesis 7>, ACG preference was found to have no moderating effect between immersion and purchase intention. In other words, regardless of netizens' preference for ACG, there was no significant difference in purchase intention according to immersion.
