This paper gives some basic requirements and preferences of various geological environmental conditions for the final deep geological repository of spent nuclear fuel (SNF). This study also indicates how the requirements and preferences are to be considered prior to the selection of sites for a site investigation as well as the final disposal in Korea. The results of the study are based on the knowledge and experience from the IAEA and NEA/OECD as well as the advanced countries in SNF disposal project. This study discusses and suggests preliminary guideline of the disposal requirements including geological, mechanical, thermal, hydrogeological, chemical and transport properties of host rock with long term geological stabilities which influence the functions of a multi-barrier disposal system. To apply and determine whether requirements and preferences for a given parameter are satisfied at different stages during a site selection and suitability assessment of a final disposal site, the quantitative criteria in each area should be formulated with credibility through relevant research and development efforts for the deep geological environment during the site screening and selection processes as well as specific studies such as productions of safety cases and validation studies using a generic underground research laboratory (URL) in Korea.

Hybrid is explained based on the logic of combination such as cross, melding, permeation, fusion, convergence etc. Such combination shows that it is more creative and effective in case of heterogeneity as compared to homogeneity and the same kind, and hybrid character has its meaning as a mean to produce a new creative image. In the context, this study aims to analyze influencing relationship through a practical analysis on how formative requirements for hybrid characters affects consumer preference. For the foregoing, this study conducted multiple regression analysis having familiarity, originality, meaningfulness, diversity as independent variables for formative requirements for characters, and consumer preference as a dependent variable. Analysis results show that familiarity, originality, diversity have a positive effect on consumers, whereas, meaningfulness has no significant impact on the consumer preference.

The purpose of this study was to analyze the recognition of those majoring Library & Information Science on the jobs that they can get and want to work for, employment requirements and their preparation, to identify problems and to suggest how to improve current status. To this end, the jobs and employment rate reported by most of the Depts. of Library & Information Science and the preferred jobs and preparation to those majoring library and information were surveyed with 107 students studying in the Dept. of Library & Information Science in the K University as the subjects. According to the results, 49 jobs were identified as the jobs that those majoring Library & Information Science could get into. In the 1st to 20th job ranking groups, 82.1% of all identified jobs, librarian job took lower ranking as 29.2% while other jobs accounted for 52.9%. However, among the jobs from the 1st to 20th ranking accounting for 96% of all jobs that the subjects wanted to have, the librarian job took 45.8% and other jobs 50.6%, which suggested that the preference on librarian job was slightly increased among the jobs that the subjects wanted to have. Furthermore, the employment requirements were classified into religion, language, scholastic achievement, certification and experience. In accordance with investigation on requirements from employment announcement, 92% were in the generally acceptable level or insufficient level. On the basis of such results, it is suggested to introduce a variety of jobs to students and to provide Case-by-Case employment guidance for improvement of employment rate and social capability of students.

본 연구의 목적은 설문조사를 통해 주민들이 실정에 맞는 거주자우선주차제의 실행 요건을 결정하는데 있다. 연구의 구성은 제2장에서 거주자우선주차제의 이론적 배경을 검토 하고, 제3장에서는 실행요건의 결정을 위한 연구분석의 틀을 제시하며, 제4장에서는 설문조 사의 방법과 조사내용에 대한 분석결과를 제시한다. 마지막으로 제5장에서는 결론과 정책건 의로 맺음한다. 이론적으로 분석결과 거주자우선주차제는 주차수요관리와 주차장공급촉진이 라는 2원적인 목표를 내재하고 있는 것으로 나타났다. 그결과 허가요금, 시행시간대 등의 실 행요건을 결정하는데 있어서 다양한 외부요인들을 고려하여야 할 필요가 있으며, 외부요인 들은 거주자들의 사회경제적 특성, 주거환경적특성, 주차행태적 특성, 기타특성 들로 구성된 다. 실행요건을 결정하기 위해 주민들에 대한 설문조사를 실시하였고 그 분석결과는 다음과 같다. 1) 요금수준 결정시 차고지 공급 목적일 경우 높은 수준의 요금을 부과하되 지역적 소득수준을 감안 하여야 하며, 목적이 수요관리에 있을 때는 외부인에 대한 규제만 하면 되 기 때문에 주민들에게는 무료이거나 가능한 낮은 요금을 징수하는 것이 바람직하다. 2) 공 간적 범위는 주민들의 근거리주차 선호 때문에 블록단위 또는 세가로를 중심으로 시행하되, 집앞돌폭이 4m 미만이거나 8m 이상일 경우에는 공간적 범위를 넓게 잡는 것이 바람직 할 것이다. 3) 주차면 배정은 독점적 사용권을 부여하는 방식이 공공재의 사유화라는 부작용 및 주차면의 비효율적 사용이라는 측면이 있기 때문에 가능한 공동이용방식을 채용함이 바 람직 한 것으로 나타났다. 4) 외부인 주처허가는 전용주택가 지역에서는 허용하여도 그리 큰 문제는 없을 것이나, 외부인 주차수요가 많은 지역에서는 무조건적 허락보다는 요금지불, 주차확인증과 같은 제도적 보완을 통해 허용해야 한다. 5) 시행시간대 결정시 전용주거지역 에서는 야간만 실시하여도 문제가 없으나 그외 지역에서는 주차수요를 고려하여 주간 또는 전일로 시행할 필요가 있다. 특히 주차문제가 하루종일 발생하는 경우와 출퇴근시 주차문제 가 많은 곳에서는 하루종일 시행할 필요가 있다. 그러나 차고지 확보율이 지나치게 낮은 곳 에서는 야간시 주민반대에 부디칠 가능성이 크기 때문에 차고지 여건이 개선될 때 까지는 시행을 보류할 필요가 있을 것으로 판단된다.

This study suggests the user's needs for a smart parking service that enables parking lot search and advance reservation service, and is a study on the user's preference selection model related to fees (reservation fee, penalty fee), etc. Two types of user preference models in the form of logit models were constructed by composing a response questionnaire for smart parking service. The first is a model for selecting a smart parking lot, which suggests a situation in which the probability of selection is higher than that of a general parking lot in the relationship between usage fee and cost. The second is a parking ticket reservation discount selection model, and the smart parking service selection probability was analyzed through the relationship model between the reservation amount and the penalty. It can be used as a design requirement that enables sophisticated and various types of smart parking service considering users' preferences.

본 연구의 목적은 소음진동규제법을 비롯한 각종 소음진동관련 규정의 목적이나 정책의 목표에 기술된 '정온'의 의미를 명확히 하는 것이다. 이를 위해 먼저 사운드스케이프 사상에서 나타난 소음의 개념과 쾌적성을 고찰하고, 관련 연구자의 '정온'에 대한 정의를 검토하였다. 그 결과 '정온'은 조용함으로서 양호한 음환경 조성의 기본 요건이지만, 그것만이 절대적 의미의 정온이 아니며 high acoustic quality의 관점에서 사람들이 선호하는 소리가 포함되고 원하지 않은 소리를 마스킹할 수 있는 유쾌한 환경까지를 포함한 상대적 의미가 되어야 함을 알 수 있었다.

To verify the suitability of the Railroad safety requirements analysis, the actions of the function which it follows in a given operation condition are composed of the rule model or the state model. And it test must be possible. The subject of condition transfer in compliance with the transfer condition which is an event of system it will be able to accomplish the operation of system. However, tasks allocated to the actor are the duty which is added in organization. This time, the start of duty task is started in compliance with an external or internal condition. If there are 9 tasks which have one objective, the relationship among the previous and the current internal tasks and next tasks which will given is able to show in logical model. Thus when planning an organization, the integral part of class must include Task, Role and Position. And this time we make a series of outputs of examination of organizing model and examples to meet the capable skill.

This study analyzed current use of 2-block haircut styles and preferences for accurate understanding of the haircut and enhancement of its efficiency. For this, a questionnaire survey was performed against 441 men in their 20~40s living in Jeollanam-do from June 27 to July 6, 2019. A total of 430 copies were used for final analysis. The collected data were analyzed by frequency analysis and cross-tabulation analysis, using SPSS 21.0, and the results found the followings: When asked about the factors affecting their choice of the haircut, 58.4% (20~40s in age) responded, 'my own decision'. Second, 61.2% said that they were interested in a 2-block haircut, and 54.7% responded that they had the haircut before. Among them, 92.3% said that they were satisfied with the trendy undercut. The above results confirm that men's appearance management is now essential, considering changes in social environments. People envision their hairstyle and visit a hair salon based on their own will, not after recommendation from their acquaintances. Many customers prefer a 2-block haircut because they believe it looks good on them. In addition, they choose the easy-to-care undercut to have a clean and neat image. It is anticipated that the study results would make a contribution to suggesting basic academic data and enhancing sales in a 2-lock haircut which is expected to remain popular. Therefore, it proposes in-depth studies on new 2-block haircut styles for women.
