The baby boomers born between 1955 and 1974, recently called the new age, form a huge population group and show characteristics different from the previous traditional older generations. With the retirement of those who make up 33% of the nation's population in earnest, the emergence of a new generation of the elderly population and policy changes are required. The new middle age generation, also called the opal generation, want to spend their old age productively and autonomously, which has increased due to the increase in life expectancy, and have some economic ability, such as enjoying overseas travel in old age. As preparation for old age is insufficient, policy attention is required for the younger generation as a new generation. In this paper, focusing on the baby boom generation, the definition of the opal generation, their consumption lifestyle, attitudes, social activities, leisure activities, and lifestyle such as health efforts are investigated, and job creation, social re-education, and local It is intended to present practical measures for preparing for old age, such as the establishment of medical facilities and social consideration for a leisurely cultural life.

Recently student portfolio is widely used as an evaluation method for self-directed performance in engineering education of the university. Especially, as many of the Innovation Centers for Engineering Education and ABEEK held student portfolio competitions, a lot of students in engineering college participate in student portfolio includes the contents and careers of the entire process of university. However, except for courses related to capstone design, there are few regular courses applied to Learning Portfolio in engineering education. Through using Learning Portfolio in courses, students take opportunities of organized collection of learning contents and critical reflection. Under these background study, the regular course in engineering education is may be appropriate for using Learing Portfolio in lecture. In this paper, we present the case study for the Data Structure course opened in the first semester of 2013 which is organized as a Learning Portfolio. According to the results of applying Learning Portfolio to the regular course, it turns out that learners can develope self-directed learning ability in exploring the learning process, and manage a learning process systematically through self-reflection in learning process.

With the rise of internet and e-commerce, this is more applicable now than ever. People rely on computer networks to provide them with news, stock prices, e-mail and online shopping. People's credit card details, medical records and other personal information are stored on computer systems. Many companies have a web presence as an essential part of their business. The research community uses computer systems to undertake research and to disseminate findings. The integrity and availability of all these systems have to be protected against a number of threats. Amateur hackers, rival corporations, terrorists and even foreign governments have the motive and capability to carry out sophisticated attacks against computer systems. Therefore, the field of information and communication security has become vitally important to the safety and economic well being of society as a whole. This paper provides an overview of IDS and IPS, their functions, detection and analysis techniques. It also presents comparison of security capability and characteristics of IDPS techniques.

In the game balancing. it is so difficult to choose suitable arms among various actions, or arms and to accurately calculate to which level we adjust the balance. The fuzzy method can be properly used in a particular environment which cannot be correctly processed in mathematics or in lessening the time-consuming problems during the accurate number crunching. Because a variety of actions, relations with opponents. previous battle experiences etc. are not easy to be reflected in every occasion, the fuzzy method could be useful in these cases. When the balancing is needed. the data which have been played to that Point are processed by the fuzzy function and calculated to adapt intensity to each action. The ability of characters is regulated in this process. To demonstrate the efficiency of this method. I would like to make clear the excellence of fuzzy method through the following five experiments; a case with invariable ability adjustment, a case adjusted by a randomly chosen action, a case with the strongest weapon selection. a case with the weakest weapon selection and a case with the fuzzy method application.

도심지에서의 우수관거시스템의 경우 적정 설계빈도 기준에 따라 유입량에 따른 적정 통수능을 확보할 수 있도록 설계되고 있다. 유입량에 동반되는 토사량의 경우 관내 퇴적 방지를 위한 적정 설계유속 조건 반영을 통해 관내 퇴적이 이루어지지 않도록 고려하고 있다. 그러나 2011년 7월 우면산 토사피해, 2014년 8월 금정산 토사피해와 같이 실제 발생한 주요 침수피해들의 경우 다양한 피해발생 원인들 중 관로 내 토사퇴적에 따른 우수관로의 통수능력의 저하되는 문제점이 지적되었다. 설계 시 적절히 고려하지 못한 토사의 유입은 관내 토사 퇴적으로 이어지고 결과적으로 통수단면 저하에 따른 월류발생 및 도심지 내 침수피해가 발생으로 이어지게 된다. 따라서 이러한 문제를 해결하고 기존 관거의 통수능력을 적절히 확보하기 위해서는 관거 내의 퇴사량에 대한 분석과 이를 고려한 관로 설계가 필수적이다. 도시유역에서 일반적인 우수관거로 유입되는 토사의 경우 산지유역과 달리 비교적 작은 입경을 가진 토사들로 구성된다. 즉, 유입되는 토사량에 있어 입경의 적정 크기 및 분포에 따라서 관거내 토사 퇴적량이 달라지게 되며 이를 해소할 수 있는 유속 범위에 대한 분석이 필요하다. 본 연구에서는 토사 입경별 관내 유속에 따른 퇴적양상을 검토하기 위하여 특정 제원의 관거 및 우수관거로 유입되는 토사의 입경들을 기준으로 관내 수심의 변동에 따른 우수관거를 지나는 각입자별 부유 퇴적의 기준이 되는 한계유속 조건을 산정하였으며, 이를 고려한 관거의 경사도 조정을 통해 설계유량에 따른 관거 내 토사퇴적량 변화를 살펴보았다. 이때, 관로내에 일정량의 토사가 지속적으로 유입되는 것으로 가정하였으며, 유입되는 토사의 입경을 0.1mm~30.0mm까지 세분화하여, 유입되는 토사 전량에 대한 입경을 하나의 입경으로 고정시킨 조건으로 관내 유속에 따른 퇴적 양상의 변화를 검토하였다. 향후 해당 조건을 반영한 설계방안의 경우 설계강우에 대한 고려를 통하여 신뢰도 측면에서 관거내 토사의 퇴적과 유속 관계에 대한 분석을 바탕으로 이루어져야 하며, 이를 통하여 일반적인 관거의 설계 기준이 수립될 필요가 있다고 판단된다.

The goal of this study was to develop a curriculum based on practice and job competency, reflecting opinions on the required job competence of nail practitioners and professionals related to nail beauty. Through in-depth interviews with nail experts, the research focuses on developing nail beauty competency-based curriculum and curriculum profiles that reflect practitioners' needs of job competence in the field. In-depth interviews with 11 field experts and surveys of 154 people were conducted to develop a competency-based curriculum for beginner nail hairdressers. The results of this study show that the existing 38 National Competency Standards (NCS) job competencies were reduced to 21 job competencies. In addition, based on the common opinions of experts who reflect the current trend, two tasks on "eyelashes" and "waxing" were added, and they were modified and supplemented with 23 core competencies. The development of a competency-based curriculum and educational programs for nail beauty was performed based on the requirements of the core competencies investigated and the development of a systematic map for the core competencies of beginner nail technicians and hairdressers. In conclusion, the need for professional education and training for nail hairdressers is growing, and it can be seen that a curriculum building multi-faceted abilities is needed for their qualifications as experts. This study found that it is necessary to develop interpersonal communication skills that include marketing elements other than practical skills such as personality and customer response methods in the nail beauty curriculum.
