  • In many countries, the Government enacts tax laws in order to manage tax collection and regulate the macro-economy. According to Noor, Jamaludin, Omar, and Aziz (2013), tax non-compliance is a growing concern because of its negative effects on the state budget. The main objectives of this article are to identify the factors affecting corporate income tax non-compliance of enterprises in Ho Chi Minh City in accordance with the current situation of Vietnamese tax administration. We use several research methods, including the exploitation of information and practical experiences from both taxpayers and tax authorities; with Probit regression model on a sample of 187 enterprises that have been inspected or examined by tax authorities in Vietnam during the period from 2013 to 2017.The article identified eight factors affecting corporate income tax (CIT) non-compliance: (1) working capital/total assets; (2) revenue/total assets; (3) total debt/total assets; (4) loss in the previous year; (5) receivables/revenue; (6) the size of enterprises; (7) tax administrative penalties/tax payable; and (8) business field. In particular, the tax non-compliance was studied as a violation of Vietnamese tax laws by enterprises declaring an insufficient amount of CIT payable to the State budget.

  • Objective: This study aimed to (1) evaluate the effects of maxillary second and third molar eruption status on the distalization of first molars with a modified palatal anchorage plate (MPAP), and (2) compare the results to the outcomes of the use of a pendulum and that of a headgear using three-dimensional finite element analysis. Methods: Three eruption stages were established: an erupting second molar at the cervical one-third of the first molar root (Stage 1), a fully erupted second molar (Stage 2), and an erupting third molar at the cervical one-third of the second molar root (Stage 3). Retraction forces were applied via three anchorage appliance models: an MPAP with bracket and archwire, a bone-anchored pendulum appliance, and cervical-pull headgear. Results: An MPAP showed greater root movement of the first molar than crown movement, and this was more noticeable in Stages 2 and 3. With the other devices, the first molar showed distal tipping. Transversely, the first molar had mesial-out rotation with headgear and mesial-in rotation with the other devices. Vertically, the first molar was intruded with an MPAP, and extruded with the other appliances. Conclusions: The second molar eruption stage had an effect on molar distalization, but the third molar follicle had no effect. The application of an MPAP may be an effective treatment option for maxillary molar distalization.

  • In this study, we analyzed the characteristics of wind speed and wind direction at different locations in Jeju area using past 10 years observed data and used them in our wind power forecasting model. Generally the strongest hourly wind speeds were observed during daytime(13KST~15KST) whilst the strongest monthly wind speeds were measured during January and February. The analysis with regards to the available wind speeds for power generation gave percentages of 83%, 67%, 65% and 59% of wind speeds over 4m/s for the locations Gosan, Sungsan, Jeju site and Seogwipo site, respectively. Consequently the most favorable periods for power generation in Jeju area are in the winter season and generally during daytime. The predicted wind speed from the forecast model was in average lower(0.7m/s) than the observed wind speed and the correlation coefficient was decreasing with longer prediction times(0.84 for 1h, 0.77 for 12h, 0.72 for 24h and 0.67 for 48h). For the 12hour prediction horizon prediction errors were about 22~23%, increased gradually up to 25~29% for 48 hours predictions.

  • Objective: The purpose of this study was to investigate the relationship between the mandibular dental and basal arch forms in subjects with normal occlusion and compare them with those of Class III malocclusion using cone-beam computed tomography (CBCT). Methods: CBCT images of 32 normal occlusion (19 males, 13 females; 24.3 years) and 33 Class III malocclusion subjects (20 males, 13 females, 22.2 years) were selected. Facial axis and root center points were identified from the left to right mandibular first molars. Distances between the facial axis and root center points for each tooth were calculated, and 4 linear and 2 ratio variables were measured and calculated for each arch form. The variables were compared between groups by independent t-test. Pearson correlation coefficient was applied to assess the relationships between dental and basal variables within each group. Results: The mandibular dental and basal intercanine widths were significantly greater in the Class III group than in normal occlusion subjects (p < 0.05). The dental and basal intercanine widths as well as the dental and basal intermolar widths were strongly correlated in normal occlusion and moderately correlated in Class III malocclusion. Conclusions: The dental arch form demon strated a strong positive correlation with the basal arch form in the normal occlusion group and moderate correlation in the Class III malocclusion group. These results might be helpful for clinicians to have a better understanding of the importance of basal arch form in the alveolar bone.

  • The purpose of this study is to examine the factors associated with reporting intention and behavior in relation to child abuse among elementary school teachers in Korea based on the Theory of Planned Behavior. The Scale, which includes demographics, preparation level of training, school characteristics, reporting-related behavior, reporting intention, knowledge, attitudes, subjective norms, and self-efficacy, was used to collect the data. A total of 292 teachers provided data. The result of this study is as follows. First, even though the teachers had suspected the child abuse, 16.3% of them reported, whilst 83.7% of them did not. In terms of teachers' reporting intention, the vignettes of very serious cases were higher than the vignettes of less serious cases. The teachers' reporting intention of sexual abuse was the highest among the types of child abuse, and it was followed by physical abuse, neglect and emotional abuse. Second, knowledge, attitudes, subjective norms, and self-efficacy, all of these variables had positive impacts on teachers' reporting intention. Meanwhile, self-efficacy, reporting intention, and the support level of specialists also had positive impacts on reporting behavior. Additionally, women or postgraduate teachers had a higher possibility to make a report than men or undergraduate teachers. These findings suggest that increasing self-efficacy through education and more thorough training about identifying and reporting on child abuse is more important than anything else for detecting abused children at an early stage.

  • Geographical differences in the incidence of amyotrophic lateral sclerosis (ALS) have been reported, and there are still many unresolved problems. The incidence as well as epidemiologic data of ALS is not known in Korea. Web-based multicenter registry of ALS, the Korean ALS registry, was established at January, 2011. The aim of "the Korean ALS registry" is the following: (1) to establish a database for the prospective collection of epidemiological information; (2) to assess the incidence and prevalence; (3) to find the temporal and geographic trends in the disease; (4) to define the full clinical spectrum of the disease; (5) to develop treatment guideline based on the database.

  • 본 연구의 목적은 영남권 지역주민의 구매 활동(쇼핑), 여가 활동, 친교 친지방문 등 사회문화적 활동에서 나타나는 지역 간 연계 구조를 사회네트워크분석을 중심으로 고찰함으로써 사회문화적 측면에서 영남권 내부의 지역 연계성을 파악하는데 있다. 국가교통 DB센터에서 제공하는 2012년 기준 시 군 간 목적별 여객 통행량 O-D 자료를 NetMiner 4.0을 활용하여 분석하였다. 분석결과 영남권은 낙동강 유역분지라는 등질적 자연환경과 오랜 역사적 발전과정의 공유에도 불구하고 대구 경북권과 부산 울산 경남권 간의 사회문화적 연계의 긴밀도가 관념적으로 생각하는 것만큼 강하지 않은 것으로 나타났다. 특히 본 연구는 경북 북부지방의 상대적 고립성이 매우 강한 것을 보여주고 있으며 영남권의 단일 지역성에 대하여 지금까지 관념과는 다른 시사점을 제공한다.

  • 이 논문은 도시 연계성에 관한 문헌들을 검토한 후 다중심도시지역의 개념과 분석기법을 제시하고, 이를 활용하여 영남권 도시들 간 화물통행량을 분석하여 도시 연계성과 다중심성을 고찰하고자 한다. 분석 결과, 영남권의 도시 네트워크는 흐름의 대칭성(즉 유입과 유출 통행량의 차이)에 있어 도시별로 상당한 차이를 보이지만, 엔트로피 지수로 보면 상대적으로 분산적인 흐름을 나타내고 있다. 또한 지배력 지수로 보면, 영남권 도시네트워크는 수도권에 비해 훨씬 다중심적(즉 비계층적) 특성을 보인다. 그러나 부산과 울산은 상대적으로 지배력 지수가 높고 이 도시들에 의존하는 연계도시들이 많은 반면, 대구는 지배력 지수가 상대적으로 낮고, 의존적 연계도시들의 수도 적게 나타난다. 결론적으로 제조업 부문별 화물 네트워크는 1위 도시인 부산을 중심으로 흐름이 집중하는 양상을 보이지만, 전반적으로 영남권 도시지역은 다중심도시지역의 특성을 상당히 보인다는 점에서, 다중심적 지역발전 정책이 권장될 수 있다.
