The requirements have been changed during development progresses, since it is impossible to define all of software requirements. These requirements change leads to mistakes because the developers cannot completely understand the software's structure and behavior, or they cannot discover all parts affected by a change. Requirement changes have to be managed and assessed to ensure that they are feasible, make economic sense and contribute to the business needs of the customer organization. We propose a feature-oriented requirements change management method to manage requirements change with value analysis and feature-oriented traceability links including intermediate catalysis using features. Our approach offers two contributions to the study of requirements change: (1) We define requirements change tree to make user requirements change request generalize by feature level. (2) We provide overall process such as change request normalization, change impact analysis, solution dealing with change request, change request implementation, change request evaluation. In addition, we especially present the results of a case study which is carried out in asset management portal system in details.

비정상 행위에 대한 true/false 방식의 공격 탐지 및 대응방법은 높은 오탐지율(false-positive)을 나타내기 때문에 이를 대체할 새로운 공격 탐지방법과 공격 대응방법이 연구되고 있다. 대표적인 연구로는 트래픽 제어 기술을 이용한 단계적 대응방법으로, 이 기술은 비정상 트래픽에 대해 단계적으로 대응함으로써 공격의 오탐지로 인하여 정상 서비스를 이용하는 트래픽이 차단되지 않도록 하는 기술이다. 비정상 트래픽 중 포트스캔 공격은 네트워크 기반 공격을 위해 공격대상 호스트의 서비스 포트를 찾아내는 공격으로 이 공격을 탐지하기 위해서는 일정 시간동안 특정 호스트의 특정 포트에 보내지는 패킷 수를 모니터링 하여 임계치와 비교하는 방식의 true/false 방식의 공격 탐지방법이 주로 사용되었다. 비정상 트래픽 제어 프레임워크(Abnormal Traffic Control Framework)는 true/false 방식의 공격 탐지방법을 이용하여 공격이 탐지되었을 때, 처음에는 트래픽 제어로 대응하고 같은 공격이 재차 탐지되었을때, 차단하여 기존의 true-false 방식의 공격 탐지 및 대응방법이 가지는 높은 오탐지율을 낮춘다. 하지만 포트스캔 공격의 특성상, 공격이 탐지된 후 바로 차단하지 못하였을 경우, 이미 공격자가 원하는 모든 정보를 유출하게 되는 문제가 있다. 본 논문에서는 기존의 True/False 방식의 포트스캔 공격 탐지방법에 퍼지 로직 개념을 추가하여 공격 탐지의 정확성을 높이고 기존의 탐지방법을 이용하였을 때보다 신속한 트래픽 제어 및 차단을 할 수 있는 방법을 제안한다.

Giving behavior promotes social solidarity and lessens social deprivations by voluntary practices to make better communities. Despite the increasing trend of giving in terms of participation and amount in Korean society, the giving culture has deeply rooted in charitable emotion based on compassion, still far from social solidarity. This paper attempts to identify giving behavior by investigating its characteristics and changes in its motives from the compassion-based social welfare to social responsibility and community solidarity, centering around 'Yellow envelope campaign' started in 2014 to support the living expenses and cost of litigation for the fired workers of Ssangyong Motors. By employing questionnaire survey and in-depth interview, it analyzes the horizontal relationships, reciprocal responsibility, social capital, and pursuit for conflict solution. Even though the campaign didn't change our society as a whole, but it cast the social questions on the birth of social empathy and solidarity.

The study examines how the discourse on infants' smart media use has been constructed under media-saturated situations. Infants' use of smart media has been regarded as a dangerous activity, rate of overdependence has been increasing. Newspapers during the recent three years (2018-20) were analyzed. The most prominent speakers in the news field were smart media content producers and platform operators. There were negative views and concerns about infants' smart media use by academics, civic groups, and parents. However, the industry went beyond these risk discourses and gave positive meaning: Smart media was redefined as safe media for infants and reliable childcare helpers for parents. Parents were portrayed as those responsible for their children's media use and in need of help for childcare, rather than being blamed for their children's overdependence on smart media. Digital parenting seems to be emerging as an acceptable and practicable way of childcare rather than harmful and incomplete parenting.

This study intends to apply the concept of reputation as a tool to positively build an evaluation of the CEO, the CEO of a company. It aims to develop tools to manage the reputation of the CEO and empirically explore the value of the tools use. As a result of the study, reliability, customer management, strategic vision, employee management, and social responsibility were derived as the constituent factors of CEO reputation, and it was confirmed that the relationship between CEO reputation and organizational favorability was statistically causal. Furthermore, the relationship between CEO reputation and product purchase intention was also statistically significant. It was confirmed that if the CEO's reputation was positively managed, it could help the stakeholders to evaluate the company to which the CEO belongs, as well as to purchase the products provided by the company. One of the ways to be well-received by various stakeholders in a corporate environment where uncertainty is intensifying is a reputation management system for CEOs, and CEOs themselves should recognize that their reputation can affect the organization and pay attention to reputation management.

This study interpreted a traditional garden of Korea through reception aesthetics. The 'gap' of acceptable aesthetics is found in the 'distance that occurs between writers and readers'. This study aims to interpret this gap between what the writer intends and what the reader expects. Boundaries do not limit traditional spaces in Korea and, therefore, are not limited by characteristics. These characteristics were studied from the perspectives of the author, the work, and the reader. The aspect first looked at the life and ideas of the gardener, the second analyzed the form and structure of the garden, and the last examined writings, from the past and present, of those who appreciated the garden. From the author's perspective, Sosoewon was understood as a garden that embodied the philosophy of Yang Sanbo. Second, the duality and indeterminateness were recognized as two characteristics of this work; artifacts in the garden were arranged in a natural form, and the gardens have indefinite boundaries, so they can be freely expanded and reduced. Finally, from the reader's perspective, it was noted that the beauty of this garden is enhanced through poetry, painting, and writing. Thus, historic gardens of Korea can be open spaces where the meaning of the garden is enriched through the free participation of viewers based on their own ideas.

As the global climate change emergency is escalating, the need for 'Social Action-Oriented SSI (SAO-SSI) on climate change topics' in science education that can change society through social activity is increasing. By employing sociocultural theory, this study explores the challenges of limiting teacher's agency in implementing SAO-SSI on climate change topics in science education. Data from participant observation for 46 lessons, in-depth interviews with participants, field notes, and teacher reflection notes were analyzed by the structure of into micro- (classrooms), meso- (school), and macro- (Korea society) level. At the micro-level, the teacher's new attempts of SAO-SSI on climate change topics class made it difficult for him to identify students' understanding of climate change, because they have a low sense of perception that climate change is also their problem. In addition, the teacher had difficulties leading students' into an engagement for social action because students were skeptical about the feasibility of planned social behavior by positioning themselves as children or had difficulty in understanding social action and sympathizing with its values. At the meso-level, a school culture that encourages the implementation of a curriculum similar to that of colleagues, it was difficult to implement one's own curriculum. And it was difficult to develop expertise without the support and communications with colleagues who revealed the burden of unfamiliar science topics of climate change. In addition, conflicts arose in the process of implementing out-of-school social actions with the principal's passive support. At the macro-level, the insufficient proper material resources for SAO-SSI on climate change topics class, and negative perceptions on the students' social action in the society were acting as constraints. We offer implications for what kind of structural support and efforts from various subjects in the educational community should be provided to implement SAO-SSI on climate change topics class in science education.

This paper attempts to divide the narrative into three levels and review the approach methodology to understand Princess Bari as a narrative. If the stratification of the narrative, the analysis of each levels, and the integrated approach to them are made, this can contribute to suggesting new directions and ways to understand and study Princess Bari. The story level of Princess Bari, the surface structure, is shaped by the space movement and the chronological sequential structure of the life task that started from the birth of the main character. This story shows how a woman who was denied her existence by her father as soon as she was born finds an ontological transformation and identities through a process. Especially, the journey of finding identity is mainly formed through the events that occur through the relationship with family members. This structure, which can be found in the narrative level, forms a deep structure with the oppositional paradigm of family members' conflict and reconciliation, life and death. The thought structure revealed in this story is the problem of life is the problem of family composition, and the problem of death is also the same. In response to how to look at the unified world of coexistence of life and death, this tradition group of myths makes a relationship with man and God. This story is mainly communicated in the Korean shamanistic ritual(Gut) that sent the dead to the afterlife. Although the shaman is the sender and the participants in the ritual are the receivers, the story is well known a message that does not have new information repeated in certain situations. In gut, the patrons and participants do not simply accept the narrative as a message, but accept themselves as codes for reconstructing their lives and behavior through autocommunication. By accepting the characters and events of as a homeomorphism relationship with their lives, people accept the everyday life as an integrated view of life and death, disjunction and communication, conflict and reconciliation, and the present viewpoint. It can not change the real world, but it changes the attitude of 'I' about life. And it is a change and transformation that can be achieved through personal communication like the transformation of Princess Bari into god in myth. Thus, Princess Bari shows that each meaning and function in the story level, composition level, and communication level is related to each other. In addition, the structure revealed by this narrative on three levels is also effective in revealing the collective consciousness and cultural system of the transmission group.

Two controversial issues exist in interpretation of "Force Majeure" set forth in the Article 931 (4) of the Korean Commercial Code. Firstly, its scope of application is ambiguous. Secondly, there is a concern that the "immunity" under paragraph 1 and "Force Majeure" may overlap each other. "Force Majeure" refers an event resulted from either natural disaster or 3rd-party. Meanwhile, the latter implies relatively extensive and comprehensive meaning and its interpretation may vary depends on law enforcement. In general, the aircraft accident hardly results in damage or loss to the 3rd-party. Additionally, it is worth to review newly enacted clause and to define its applicability. When the 3rd party is suffered from damage or loss incurred by any external act, it is necessary to explicit the concept of the non-contractual liabilities with respect to 3rd party. From the perspective of protecting aviation industries, the commercial aviation operator may be entitled to immunity in respect of claim for damage incurred by the event of Force Majeure. However, this approach is directly opposite to the victim's benefit and protection by the law. Therefore, the priority of the legal protection should be considered. Although the interest of the commercial aviation operator is not negligible, the protection of the law should be favorable to the 3rd party. Otherwise, the innocent party has no right to claim for damage incurred by aviation accident. Another issue is about the possibility of overlapping of the provision set forth in the paragraph 1 and 4. The former states that the liabilities shall be exempted on account of either the unsettled political or economic situation but this clause is inconsistent with the interpretation on Force Majeure under the latter. As argued above, this may include any event resulted from either political or economic account by the external influence of the 3rd party, thus these two provisions are overlapped. Consequently, in order to develop ordinances and guidelines and to ensure an equal protection to both parties, above two issues must remain open for further discussions.

This study aims to examine the processes of changes of the two main roles, Sangjwa(the young Buddist monk) chum and Omjung(the monk with a boil on his face) chum, performed in Yangju Byeolsandae Nori, on the basis of Chumsawi (dance-movement). Above all, having studied many artistic remains performed by Jo jong sun, Jung han gyu, Park jun seup, Kim sung tae from 1929 to 1942, two main roles, in which Geodeureum chum is now an essential part in almost all performances, were then played only in Kkaekki chum to Taryong Jangdan without performances of Geodeureum chum. In case of Sangjwa chum, players had performed ad libitum and without restraint only on the basis of five sorts of Kkaekki chum's movements. In Omjung chum, witty remarks along with the drama had become more important factors than dances. Let alone two main roles, other parts then also showed no big changes in dance performance. Performers just tried to maintain its slender existence within stifling atmosphere because of oppressions and restraints during the Japanese imperialism. After the restoration of independence in 1945, Kim sung tae and his disciples made a great effort on the restoration of Talnori. During the Korean war, many players also endeavored to keep a good track of Talnori, teaching and training their young followers. Especially performers such as Park jun seup, Park sang hwan, Kim sung tae, and Lee jang sun put much more efforts on restoring Talnori. From that time, Geodeureum chum began to appear in two main roles' performances. In Sangjwa's performances, Byeogsa ritual dance, which was performed to Taryong Jangdan, changed into performances to Yeombul Jangdan, and Kkaekki chum -originally slow and ritual dance, became very fast and active one. Geodeureum chum, called Yongteulim, was added in Omjung chum, so that dance had more important role in performance. Even at this time, dance movements were not clearly and completely organized and arranged, because Geodeureum chum's performance was not clearly defined as orderly dance movements but was regarded as just a movement. After Geodeureum chum being designated as a cultural treasure, Lee byeong kwon took over the task from Park sang hwan, Sangjwa chum's performer, so Geodeureum chum became much more well organzied, arranged and orderly. Geodeureum chum played by Sangjwa had almost the same order of scenes and movements as Geodeureum chum played by Yeonnip. Based on this performance, the order of dances and movements was consistently arranged and settled. Following Park jun seup's performances, Jangsam was more widely applied and used in Omjung chum than ever before, so Omjung chum became much more organized and arranged. Well-arranged Omjung chum had also almost the same dances and movements as Nojang chum's. Yeonnip and Nojang's performances were not directly and intentionally studied and applied to two main roles in Yangju Byeolsandae Nori. Players seemed to borrow those parts naturally through many times of performances. Through their persistent efforts, Jangdan and dance movements have more clearly and completely been organized, establied, and improved through many years' performances. And dance movement can be performed exactly to Jangdan, so we have more complete and orderly types of dance movements. Thanks to many performers' efforts, Sangjwa chum has been established as one that only top performer can play, and Omjung chum has become an integral part in Yangju Byeolsandae Nori.
