The objective of this study is to define a violation, a type of human errors, based on a case study in nuclear power plants. Accidents in nuclear power plants are rare-accident of large, complex and high-reliability systems. Since the damage of an accident could be extremely enormous, many efforts have been underway to prevent the human errors. Especially, the violation is a newly emerging type of human errors but its concept is not clearly defined in the nuclear industry. A total of 28 reports related to the human error accidents/failures in the last 10 years were collected from NEED (Nuclear Event Evaluation Database) in KINS-OPIS (Operational Performance Information System). The relationship between causal factors and violations were analyzed by the fault tree analysis (FTA) and the human related event root cause analysis method (HuRAM). As a result, the characteristics of violations were identified and four types of violations (routine, situational, avoidance and optimizing violations) were newly defined. The results of this study can be used to develop proactive countermeasures and implement a supervisory system for preventing violations.

Bora Kang,Chung Sik Kim,Heejin Kim,Mingyu Lee,Min K. Chung,Bong-ha Hwang 대한인간공학회 2013 대한인간공학회 학술대회논문집 Vol.2013 No.5

Objective: In this study, we investigated several factors that affect the sense of space in coach drivers’ seat, by interview with coach drivers. Background: The cockpit should be ergonomically designed because the cockpit driver’s seat is the main workspace of drivers who driving for long hours in a day and it is related to the safety of the driver and many passengers. For this, considering the sense of space that can reduce fatigue and discomfort is very important, as well as considering operability that enables efficient driving work. Method: The 34 cockpit drivers in the field were interviewed to identify whether they feel discomforts in their seat or not and what situations and what factors of coach influence the sense of space. To get more specific information, the cockpit space was subdivided into 4 spaces; the whole space, the front space, the rear space, and the space for ingress/egress. Results: Overall, the degree of the identified discomfort was not critical but there were things to be improved. For each space, related factors were identified and those factors are as follows; the space size in the whole space, the distance from pedal to steering wheel in the front space, the distance to guard in the rear space, and the distance from guard to dashboard in the space for ingress/egress. Conclusion: In this study, by interview with coach drivers, we identified their discomforts of drivers’ seat in the sense of space and related design factors. Even though the degree of their discomforts is not critical and not significant to their driving, more pleasant working space for the sense of space should be created by resolving the existing discomforts. Application: The results of this study can be used for ergonomically designing the more pleasant and safe coach cockpit, considering ‘the sense of space’.

Bora Kang,Hong-Ju Jun,Seenyoung Park The Pacific Early Childhood Education Research Ass 2022 Asia-Pacific journal of research in early childhoo Vol.16 No.1

The purpose of this research is to analyze the factors that need to be improved to provide the quality play environment in early childhood education (ECE). This study is designed to examine the differences between the importance and performance of the play environment as perceived by early childhood teachers in Korea. For the analysis, the play environment was divided into “environment giving comfort,” “environment supporting child-initiated learning,” “environment fostering aesthetic sensitivity,” and “environment fostering creativity.” A total of 277 early childhood teachers completed the online questionnaire, and the data obtained were analyzed based on mean, standard deviation, paired-sample t-test, and importance-performance analysis. Results indicate that, first, the importance of the play environment was statistically significantly higher than performance across all areas. Second, the area where the current situation can be maintained was “environment giving comfort.” The areas requiring intensive improvement were “environment supporting child-initiated learning” and “environment fostering aesthetic sensitivity.” The area requiring gradual improvement was “environment fostering creativity.” The findings from this study have implication in providing effective play environments in ECE institutions.

Bora Kang,Eunjung Choi,Heejin Kim,Mingyu Lee,Seungjae Oh,Dong Yeong Jeong,Hanul Bang,Min K. Chung 대한인간공학회 2013 대한인간공학회 학술대회논문집 Vol.2013 No.10

Objective: In this study, to find the design tendency of gesture commands of the two groups, User Interface (UI) experts and users, we compared the results of their evaluations to gesture candidates which can be applied to domestic appliances. Background: The candidates for gesture commands of appliances can be various. To apply the gestures for appliances, the best gestures should be chosen properly by considering opinions from not only experts but also users. Method: 5 UI experts and 32 users with various range of age participated in the experiment. After watching videos showing gesture candidates, they evaluated each gesture of commands for domestic appliances such as air-conditioner, audio and door. For each gesture, the UI experts rated the overall good to match of each gesture and the users rated the preference of each gesture by the 100-point scale. Results: As a result, we derived preferred gestures with above 50 point for each command. Then we analyzed the commonly preferred gestures from two groups and only preferred gestures from users. Conclusion: As a basis for the designing suitable gestures for domestic appliances, we analyzed opinions from both the groups. This study suggests which opinions should be considered, according to kind of the groups and how they can be utilized. Application: The results of this study can be applied to designing gesture interfaces of several appliances in a smart-home.

Bora Kang,Sung H., Han,Jiyoung Kwahk,Kyudong Park 대한인간공학회 2016 대한인간공학회 학술대회논문집 Vol.2016 No.11

The aim of this study is to verify the effectiveness of sound feedback and to improve usability of mid-air pointing gesture interaction with a head-mounted display. Recently, the mid-air gesture interaction on three-dimensional space has become more prevalent with the motion recognition technology. In the interaction, sounds have been actively utilized to provide various information to users. In an experiment, there were two independent variables: FEEDBACKS (no sound feedback / case-triggered sound feedback / continuous sound feedback with varying frequency / continuous sound feedback with varying duration) and TRACKS (curved / straight). The participants performed a path following task while keeping the center of tracks. The results showed that the continuous feedbacks coupled to pointing gesture helped the participants perform the task more accurate and finally get better performance in deviation because they could easily get information about deviation and could keep concentration on their task. The results of this study can be used to enhance user experience of gestural interaction with sound feedback in various areas: virtual reality, augmented reality and large-display interaction.

This study set out to examine differences between the importance and implementation of the playing-an-instrument activity perceived by early childhood teachers according to the plan, content, method, and evaluation of an activity and environmental organization and to analyze the items that should be first supported and the ones that would require a long-term improvement for the activity in the field of early childhood education. The study conducted a survey with 291 early childhood teachers and analyzed data in mean, standard deviation, paired-sample t-test, and IPA according to the research questions. The findings were as follows: first, the importance of the playing-an-instrument activity was higher with statistical significance than its implementation across all the areas of activity planning, content, method, and evaluation and environmental organization among the early childhood teachers; and secondly, one item in the activity method area required priority supports in the playing-an-instrument activity, and four, five, and three items in the activity method, activity evaluation, and environmental organization area required a long-term improvement. These findings will provide implications for the vitalization of the playing-an-instrument activity at early childhood education institutions.

SF 속 ‘호모 뮤턴트’의 특성과 유형에 관한 연구

강보라(Bora Kang) 한국콘텐츠학회 2009 한국콘텐츠학회 종합학술대회 논문집 Vol.7 No.1

SF에 등장하는 다양한 돌연변이 캐릭터들은 상당히 긴 계보를 지닌다. 고대 그리스의 반인ㆍ반수 사티로스에서부터 늑대인간, 뱀파이어, 초능력자, 기생물체에 이르기까지 그 종류와 성격도 수백 가지에 이른다. 그러나 국내 문화콘텐츠 시장에서는 SF 장르 내 가장 유서 깊은 소재 중에 하나인 돌연변이에 대한 접근이 거의 없었을 뿐 아니라, SF 분야 자체에 대한 논의도 활발하지 못했다. 본 논문에서는 SF에 등장하는 돌연변이 중 인간과 연관된 형태만을 선별해 ‘호모 뮤턴트’라고 명명하고, 그 특성과 유형에 대해 정리해 보고자 한다. 인간과 변종의 경계를 해체하는 혼종으로 때론 생물학 적인 감수성과 인격을 내제한 채, 인간과 공생 파트너로서의 가능성까지 내비치는 SF 속 ‘호모 뮤턴트’를 살펴봄으로써, 인류사가 가졌던 그에 대한 끊임없는 상상력이 당대의 시대상과 어떤 관계를 맺고 있는지 분석해 보고자 한다. 나아가 ‘호모 뮤턴트’가 문화콘텐츠로서 명실 공히 ‘흥행코드’로 사용될 수밖에 없는 이유도 도출해 보고자 한다. The characteristic of mutant has long history, which is shown in various science fictions. There are different types and characters like Satyrs from Ancient Greek to superheroes in present. In fact, however, mutant as a cultural content has not been discussed sufficiently in Korea, even if related analyses were required indeed. In the thesis the characteristic and types of 'Homo Mutant' will be introduced and analyzed in many aspects and look for the reason why 'Homo Mutant' can be revealed and apply for further possibilities.

아카이브 액티비즘에 대한 시론적 고찰: ‘기레기’ 아카이빙 사례를 중심으로

강보라(Kang, Bora) 한양대학교 평화연구소 2021 문화와 정치 Vol.8 No.3

이 글은 한국사회 내에서 아카이브 액티비즘의 가능성과 의미를 탐색한다. 이를 위해 ‘기레기’ 담론이 급등한 이후, 민간 영역에서 만들어진 ‘기레기’ 아카이빙 사례를 분석대상으로 삼는다. 2021년 현재 ‘기레기’ 아카이빙 사이트는 언론이 사회의 주요한 의제를 설정하고 거대 권력을 감시하는 기능을 제대로 이행하지 못하고 있다는 전제를 바탕으로 언론 기사를 지속적으로 수집하고 유형에 따라 분류 및 평가하는 시스템을 운영 중이다. 이 같은 웹 환경에서의 아카이빙은 아카이브의 주체가 특정 기관과 전문가에서 일반 대중으로까지 확대될 수 있다는 가능성과 그로 인해 아카이브의 방식이나 내용 또한 기존의 공적 아카이브와는 달라질 수 있다는 가능성을 내포한다. 무엇보다 ‘기레기’ 아카이빙 사례가 기존의 전문지식이 관심을 가지지 않거나 설명하기 어려운 영역에 대한 정보 관계를 구성하고 있음을 주목할 필요가 있다. 이런 맥락에서 ‘기레기’ 아카이빙이 등장하게 된 사회문화적 배경을 검토하고, ‘기레기’ 아카이빙의 구조적 특징을 밝히는 가운데 이 사례가 아카이브 액티비즘의 가능성을 내포하는지 비판적으로 논의하고자 한다. 궁극적으로 분석을 통해 시민사회가 기록주체로서 재현하는 현실의 상을 이해할 수 있을 것으로 기대한다. This study was a preliminary study on the possibility and meaning of archival activism in South Korea. This study examined the private Giregi archive that was created after the 2014 Sewol ferry disaster and the surge in Giregi discourse. The Giregi archive collects, categorizes, and evaluates media on the premise that the media should set social agendas and monitor powerful actors in society, such as governments and companies, but it is not. Thus, this study was conducted to examine the emergence of the Giregi archive and its structural characteristics as a private effort. The analysis examined the Giregi archive in South Korea as a form of activism to determine its socio-cultural implications. The results of this study showed the characteristics of archival activism and the expansion of civic archives in South Korea.

한국 다문화 영화 속의 아동 캐릭터에 관한 연구-<세리와 하르>, <마이 리틀 히어로>를 중심으로-

강보라 ( Kang Bora ),배상준 ( Bae Sang-joon ) 한국언어문화학회(구 한양어문학회) 2017 한국언어문화 Vol.0 No.64

국가의 경계를 넘어 새로운 곳에서 자신의 꿈을 위해 정착하는 사람들이 늘어 나면서 한국도 다문화 사회에 진입하고 있다. 문화적 배경이 다른 사람들과 평화롭게 공존하는 방법을 모색하는 다문화주의는 영화로 들어가 새로운 사회적 가치를 창출하는 과정의 갈등과 고뇌를 담아낸다. 다문화 영화는 결혼이주여성이나 이주 노동자에 먼저 주목했기 때문에 상대적으로 소외된 다문화 아동을 주인공으로 하는 영화는 많이 제작되지 않았다. 또한 아동 캐릭터를 중심으로 한 다문화 영화 연구도 부족한 실정이다. 본고는 한국 다문화 영화 속의 아동 캐릭터를 연구하기 위하여 <세리와 하르>와 <마이 리틀 히어로>를 분석하였다. 그 결과, 다문화 아동 캐릭터는 다음과 같은 공통적인 특성을 보여주었다. 아이들은 가정과 사회에서 이중의 억압을 받으며 자신의 결핍된 부분을 인식하였다. 아이들은 자신의 결핍을 보완하기 위해 개인 및 국가 정체성 속에서 ‘나는 누구인가’에 대한 물음에 끊임없이 응답하였다. 아이들은 각자의 위치에서 나름의 방법으로 최선의 노력을 기울이지만, 미숙한 존재이기에 혼란과 좌절을 경험하기도 한다. 아이들의 정체성을 찾기 위하여 조력자와 만나는 것은 필수적이고, 여기에 결합된 아이들의 주체적인 선택은 아이들을 성장시키는 밑거름이 된다. 아동이 주인공으로 등장하는 다문화 영화는 어린 학습자에게 캐릭터에 대한 몰입감을 증가시켜주기 때문에 영화 치료나 교육적 텍스트로 활용될 가능성이 높다. 다문화 영화는 변화하고 있는 사회적 모습을 담고 있을 뿐 아니라 범교과적 접근으로 다루어지기 때문에 다문화 영화에 대한 적극적인 후속연구가 동반되어야 할 것이다. Korea is also entering the trend of multicultural society as people who go abroad and settle down increase to achieve their goals in a new world. multiculturalism seeks the way how people with different cultural backgrounds can ideally co-exist. When this comes to the aspect of films, films show the conflicts and agonies that were made in those process which also creates new social profits. The majotiry of multicultural movies focus on internationally married immigrant woman or immigrant workers so relatively there are few movies that have dealt with the story of multicultural children. Therefore, there are not much research about movies that have focused on multicultural children as well. In order to analyze the children characters in Korean multicultural movies, this paper chose < Seri & Harr > and < My little hero > as the subject. After the analysis, it was able to find some common characteristics that were shown from the multicultural children. Kids was able to feel the lacks regarding their identity by the suppressions coming from both family and society. To compensate for those lacks, they kept answering the question “who am I ?” to themselves and tried to clarify their individual and national identity. Even though children try their best to find out the answer of their identity, they go through a lot of confusion and frustration since they are immatured yet. As a result, in the process of building up their identity, it is essential to meet an assistant during the movie and when this is combined with their independent decisions, this turns into a foundation that affects their further development. Multicultural movie move in and out the subject and nonsubject boundary so it can be used diversly in education. Especially, a movie that contains a story about multicultural children enlarges immersion to the similar ages watching which can also lead to some therapeutic effects. Therefore, from now on, it is required to give continuous interests and keep up the following researches of multicultural children for further programs that should be developed in this area.
