PURPOSES : Many people recommend the expansion of the drone market and various ways of using drones. However, unreasonable expansion may cause various social problems. Therefore, criteria and systems for the expansion are required. This paper presents a review of the system using drones for managing and enforcing illegal parking, and recommendations on improvement. METHODS : This paper presents a review of the system using drones for managing and enforcing illegal parking, and recommendations on improvement. RESULTS : This study shows that new enforcement criteria are required for a new enforcement method using drones. In addition, consignment operation is needed to solve workforce shortage and secure expertise, and flight mitigation criteria are required, considering the illegal parking characteristics based on region and time. Finally, CCTV operation guidelines should be improved to clarify the definition of drone images and prevent unreasonable information collection. CONCLUSIONS : Illegal parking enforcement using drones is an efficient method that is highly feasible and solves enforcement limitation issues, such as the lack of workforce and equipment. A prior institutional review is required to apply new technologies more efficiently, and proposals on improving the legal systems with limitations are required through continuous research.

PURPOSES : In this study, the causality between smart parking user services and its satisfaction level was analyzed statistically, and a smart parking priority decision model was established in terms of the user side. METHODS :The results of the Daegu Metropolitan City survey for the parking state, parking fee, transfer, convenience of use, facilities, and safety that could influence smart parking user satisfaction were used. A structural equation model in SPSS 26 and AMOS 26 programs that facilitates hypothesis testing and importance factor analysis between observed and latent variables was used. RESULTS : The results demonstrated that the importance factor loading on smart parking user services was in the following order: convenience of use (0.996), parking facilities (0.814), safety (0.803), parking information (0.706), transfer (0.618), and parking fee (0.426). Among them, the parking fee was not quite influential in decision making. CONCLUSIONS : The most influential user service on smart parking information systems was the convenience of use, in which congestion in parking lots and parking time were the most influential variables. The most influential variables were in the following order: in parking facilities, the route design of vehicle flow and size of the parking garage; in safety, the entrance location and the level of wear; in the parking state, the availability of parking space and parking fees; and finally in transfer, the convenience of transfer to other modes and the number of transfer parking lots.

In the present study, sled analysis was conducted under the condition of 20g (20 times of gravitational acceleration) and 48 km/h of initial velocity, suggested by WC-19 to investigate the injuries of traffic minorities of tie-down type fixing inside a vehicle during crash. Also, four new parameters, which were related to angles between belts and wheelchair and their levels were limited by WC-19, were proposed and orthogonal array was prepared with different levels of each parameter. In the meantime, four parameters were optimised by minimising head injury criteria and chest acceleration of passengers in each case of the orthogonal array.

With increasing demands of transportation services for disabled or aged people, who need wheelchairs, it is recommended to install wheelchairs inside automotive vehicles. However, wheelchairs are not effectively safe devices during car crash unless they are properly fixed. So far, few data have been found related to wheelchair safety or characteristics during car crash, therefore, frontal crash simulations have been carried out based on the FE models of a dummy and a conventional wheelchair including the wheelchair fixing belts and the install plate in the present study. Head injury criteria (HIC) and motion criteria (MC) are investigated and the optimum value of the design variable was found by the Robust design.

본 연구에서는 팔로워십이 리더의의사결정방식 중 참여적 의사결정과 권한위임에 미치는 영향에 대 해 알아보고자 하며, 그 매커니즘을 밝히기 위해 LMX를 매개변수로 설정하고 있다. 기존 연구들을 살펴 보면 팔로워십에 관한 다양한 연구가 진행되어 왔으나 팔로워십이 리더에게 미치는 영향에 관한 연구는 찾아보기 어려운 실정이다. 이에 본 연구에서는 팔로워와 리더를 구분하는 가장 중요한 요인으로서 리더 의 의사결정권을 상정하여 팔로워십이 이에 영향을 미칠 수 있는지를 알아보고자 한다. 즉 팔로워의 의사결정과정에의 참여는 리더의 의지에 달려있다고 보는 기존 관련 연구들과는 달리 본 연구에서는 리더가 팔로워의 행동(팔로워십)에 따라 팔로워를 의사결정과정에 참여시키거나 의사결정권을 팔로워에게 위임 할 것이라는 가정에 기초하여 가설을 도출하고 있다. 연구결과 팔로워십 중 독립적·비판적 사고는 LMX와 참여적 의사결정, 권한위임에 유의한 영향을 미치 지 못하는 것으로 나타났다. 반면 팔로워십 중 적극적 참여는 LMX를 매개로 참여적 의사결정에는 완전 매개효과를, 권한위임에는 부분매개효과를 갖는 것으로 나타났다. 이러한 연구결과는 팔로워가 리더의영향을 받기만 하는 수동적인 존재라는 기존의 시각과 반대되는 결과이다. 즉 팔로워는 리더의 영향을 받을 뿐만 아니라 리더에게도 영향을 미치는 주체적이고 능동적인 존재가 될 수 있다는 점을 시사하고 있다.

The main goal of this study is to provide the educational contents of French grammar by means of English grammar. As one of their strong points, English has simplified the verbal and nominal inflections, but French has done the regular shape of its pronunciation. As a matter of course, they differ in the pronunciation, words, and expressions. Nevertheless, French and English have shared so many things through their history: their vocabulary and grammar on the Greco-Roman legacy have had mutual influences through Norman Conquest(1066) and the industrial revolution. So these two languages have grammatical common concepts, which are not at all: for example, the parts of speech, word order, modes, tense, passive voice, relative clauses, etc. There is not only grammatical similarity but also difference between these two languages. Basically, they have the word order SVO but French has the case SOV that contains clitic pronouns. They also show subtle disparities in the mood, the tense, the frame of verbal sub-categorization, the hiatus, etc. Though they broadly have common concepts of the article, its ordinary uses are not same. In the passive voice and the relative clauses, there is a little subtle distinction. But English grammar helps students to understand French grammar. In consequence, students who have knowledge of the former can easily acquaint the latter. Professors may lead students to reach to a higher level of French grammar by explaining common concepts and emphasizing different ones between these two languages

There are many studies which have investigated biases hidden in ELT materials, particularly reading texts. But English grammar books haven't received much attention regarding the issue because their contents are considered as instruments for explaining grammar points. This paper thoroughly examines biases in an English grammar book, Grammar in Use Intermediate(GIUI), with regard to the following two aspects: idealization of the culture of native speakers of English, and gender bias. The findings show that materialism tends to be considered as a norm putting so much emphasis on money. With regard to gender bias, there are mixed results. Males are more dominant than females with respect to appearing as main characters, initiating conversations, and being mentioned ahead of the other gender. Males and females are treated equally in participating at active sports and pursuing various occupations. On the other hand, unethical or unlawful acts are alloted to males overwhelmingly more often than to females. The findings of this study can be used as a list for checking hidden biases in English teaching materials.

This paper explores whether the English reading texts of College Scholastic Ability Tests are factually accurate. The tests which were administered over the fifteen-year period since 1996 are investigated with regard to whether the infonnation in the texts which deal with historical events or figures and real life situations is factually accurate. The results show that there are 12 test items which are not factually accurate. Some of the items which use the original texts intact or have a minor modification to them contain information which is not true when their original texts are cross checked with various sources of materials. Others have inaccurate information resulted from the revisions of the original texts such as modifying them in order to lower the difficulty of the items. In conclusion, it is suggested that every effort should be made to confirm whether the information in the reading texts is factually accurate or to sustain the information as it is as much as possible if it is accurate.
