  • 본 논문에서는 카메라 렌즈에서 흔히 발견할 수 있는 렌즈계 왜곡에 의한 영상 품질 저하 현상을 소개하고 이를 보정하는 방법을 제시한다. 렌즈계 왜곡은 크게 두 가지로 나눌 수 있는데 기하학적 왜곡과 광도 왜곡이 그것이다. 이상적인 렌즈계가 아닌 경우 이러한 왜곡 현상은 필연적으로 발생을 하게 되는데 왜곡 보정을 위해서 기존의 카메라 캘리브레이션과는 다른 방식의 접근이 필요하게 된다. 본 논문에서는 기하학적 왜곡 보정을 위한 이미지 워핑 방법을 제시하며 아울러 광도 왜곡 보정을 위한 보정 방법을 다루고자 한다.

  • 하천제방은 홍수의 위험 방지에 중요한 역할을 하며 하천의 범람으로부터 제내지의 인명, 가옥, 재산, 각종 시설물 등을 보호하기 위하여 설치되는 시설물로서 침수피해 방지와 같은 중요 기능을 가지고 있다. 이러한 하천제방의 적정규모를 결정하기 위해서는 대상지역의 수리 수문학적 특성, 지형조건에 관한 조사 및 연구 이외에 경제적인 검토가 수반되어야 하며, 제대로 검토되지 않을 경우 제방이 누수 또는 침하, 붕괴되어 범람방지 기능을 상실하는 현상이 일어나게 된다. 국내 하천유역에서도 과거 전국에 걸쳐 제방 붕괴현상이 일어나 많은 범람침수 피해가 발생하였다. 본 연구에서는 제방붕괴의 일반적인 원인으로 지적되고 있는 월류, 제체의 불안정, 과도한 변위, 급격한 수위의 감소 등으로 발생할 수 있는 현상 및 문제점들을 검토하였다. 이로부터 기하학적 인자, 수리학적 인자, 수공구조물 인자, 정성적 인자 등 4가지 분류로 구분하였으며, 총 12가지 세부인자를 제시하였다. 제시된 인자를 토대로 시험 대상유역인 감천과 남강에 적용하여 인자별 영향을 산정하였으며, 이로부터 위험도를 평가하였다.

  • This study examined the case of women's conflict experience in small and medium size enterprises. Although the number of women working in business organizations is rapidly growing in Korea, discourse about them is still scarce. Some discourse about them focuses only on the productivity and inequality aspects within the organizations. Therefore, we need to examine their organizational lives through a more dynamic and performance based perspective. Especially, because conflicts experience by women within business organizations involve a variety of organizational interactions, they reveal the vivid reality with which working women face today. The existing conflict research studies focused on communication or interpersonal relationship are limited by the fact that they have primarily dealt with the variables such as conflict management styles. However, conflict research needs a more specific and wholistic interpretation because conflicts usually depend on their contexts and interaction dynamics. Therefore, the phenomenological methodology was employed as a more appropriate method for the current conflict study. Results shows that the two themes were identified regarding the conflict content. The first and second themes were the unfair situations and the hierarchical rank respectively. The three themes were identified regarding the attitudes about conflicts. They were the passive stance toward conflicts, the recognition of the gender difference, and the acknowledgement of the importance of the relational aspect respectively. Finally, three more themes were identified regarding the conflict management styles. The first, second and third themes were the passive responding, the aggressive responding and the positive conflict management respectively. In addition, the implications of the results and the suggestions for future studies were made.

  • This study is aimed to draw the meaning and possibility of political participation of the SNS users through a phenomenological analysis of participation and awareness of authentication shot for vote of the users. Especially, the reason for focusing on 'SNS vote authentication shot' is because the creative imagination of the users and the meaning and possibility of collective intelligence are drew while citizens are participating in political activities for themselves. Theory resources are based on technical imagination of Vil$\acute{e}$m Flusser that is concerned with users and political practice in the New Media Era, creative imaginer and discussions of collective intelligence of Pierre L$\acute{e}$vy. Based on these theoretical discussions, it is aimed to select the SNS users experienced in authentication shot for the by-election for mayor of Seoul in 26. Oct. 2011 and to use phenomenological analysis model on materials collected after in-depth interview. The researchers take contextual circumstance into consideration for experiences of study participants sticking to SNS users' opinions and intersubjectivity and approach prejudice of their experiences to untouched structure of phenomenon and meaning. It is because a phenomenological study exploring "the own meaning of 'die Sachen'" is 'strict study' and method focusing on the political participation of SNS users itself.

  • This study is a qualitative study using phenomenological methods that focus on the meaning of what individuals experience to understand the meaning of the gender role of women after childbirth. The participants of this study are 17 women who gave a birth from 8 weeks of the postpartum period to a year after the birth. Seven categories were derived from the results of analyzing the meaning of the gender roles of participants, and the seven categories are confirmed to be body changes and pain, just making me feel down, the difference between expectation and reality, isolation from husband and social network, thinking about my mother as a woman, the pain of body and mind sublimates, and convergence/dissociation between femininity and motherhood. This study is meaningful in that the results of this study provided information that would have a broader understanding of women's gender role after giving birth.

  • The purpose of this study was to understand how participants' experiences of participating in self-sufficiency projects were. To do this, we analyzed phenomenological methods using in-depth interview data of 48 participants from the Central Self-Sufficiency Foundation, which is qualitative data of the "Project for Strengthening Self-Support for the Working Poor". The study revealed 214 meaningful statements and general re-statements, 24 themes, 9 themes cluster, and 5 categories. Participants' experience was found to be forced work, felt alienated from the self-sufficiency business, and could not receive a clear vision for the future. At the same time, the experience of participating is an opportunity for motivation for change in one's own life, and the essence of becoming a stepping stone to move forward for self-reliance has been derived. Based on the results of this study, we proposed a practical policy task to create a positive expectation effect.

  • This study is aimed to examine the emotional experiences of parents with children who have been sexually abused by others. Five mothers whose child was sexually abused participated in this study. They were first recruited through recommendations made by social welfare agencies that provided services to these children. We conducted two or more in-depth interviews for each mother to collect the data. The mothers' emotional experiences were analyzed using phenomenology. Mothers expressed that they felt like the whole world came crashing down around them, felt "totally lost", and felt deep pain together with their children, such that "my family and I were so devastated". Nevertheless, they gradually came to believe that they could overcome this tragedy by continuously making efforts to protect their children from the dangers outside. Despite their efforts, however, they kept the feeling of "hopelessness, neglect, and their children's wounds", deep inside them. The results indicate that it is necessary to have an intervention for mothers whose child has been sexually abused from a companions' perspective within 10 days after the sexual abuse incident.

  • The purpose of this study was to explore the meaning of early entrance experiences of science gifted high school students. The subjects were 13 students who are attending science gifted high school in Seoul. The research data were collected through in-depth interviews. The qualitative study applied the phenomenological method of Giorgi. The early entrance experiences of science gifted high school students were clustered into 13 specific themes and 5 general structures. The results indicated that the early entrance students were surprised by their admissions from the school and they worry about their lack of readiness. However, they follow up their missed 1 year study after all. It took from a few weeks to 1~2 years depending on the student. At any rate, the environment of the school such as differentiated curricular, dormitory life, and studying atmospheres were helpful for the students to adopt easily. Even though they sometimes show a little deficiency, it won't be an issue, they just corporate each other and pursue their studies. As time goes on, they become friends even though they call other students 'big brother'. When the placement of gifted students take place, we do not need to hesitate because of their age, but need to consider the environment of school and characteristics of student.
