Deep sea water is deeper than 200 m in depth and maintains cool temperatures. It is clean seawater not contaminated by E. coli and other general bacteria. Because deep sea water is a recyclable resource with high industrial value, activities for commercial use are vigorously developing. We investigated safety, quality characteristics, and mineral contents of prototype products using deep sea water as a substitute for a curing agent and compared it with existing commercially processed products. This study examined the potential of deep sea water as an alternative to curing agent solution. As a result, safety and quality characteristics of processed meat products with deep sea water were not different from commercially processed meat products, but mineral contents were higher in processed meat products with deep sea water. Deep sea water could be widely used as purity salt and purity minerals that can replace chemical substances such as chemical salts. A new, active food market using deep sea water will emerge in the near future.

웹 기술이 발달함에 따라 공공기관 웹사이트는 단순한 행정기관의 홍보에서 벗어나 국민과 정부 간의 의사소통의 증거인 동시에 업무의 기록으로서 역할을 담당하고 있다. 따라서 공공기관의 웹사이트들은 공공기록물로 인식하고 보호해야 한다. 하지만 공공기관의 웹기록물 중 하나인 심층 웹기록물은 실시간으로 상이한 페이지를 동적으로 구성하기 때문에 기존의 보존방법과는 다른 수집 보존 활용 기술이 요구된다. 국가기록원은 이러한 특징을 가지고 있는 심층 웹기록물을 장기보존하기 위해서 심층 웹기록물 장기보존 포맷인 KoDeWeb을 연구하고 개발하였다. KoDeWeb은 전자기록물이기 때문에 전자기록물로서 진본성 및 무결성을 보장해야 한다. 본 연구에서는 KoDeWeb의 전자기록물로서의 진본성 및 무결성을 증명하기 위해 국제 전자기록물 표준인 OAIS 참조모델에 KoDeWeb을 맵핑시켰다. 나아가 OAIS표준을 따르고 있는 전자기록물 장기보존 시스템에 KoDeWeb을 사용함으로써, 정부 및 공공기관의 심층 웹기록물 생성 및 수집을 체계화하고, 또한 민간이 운영하는 웹의 심층 웹기록물 장기보존에 활용할 수 있다.

Deep geological disposal of high-level radioactive waste is imperative to national safety and environmental protection and it relies on establishing siting criteria suited to the geological and social conditions of each country. This paper compares the various geological and social criteria applied by different countries in the process of securing sites for the deep geological disposal of high-level radioactive waste. The present comparative analysis considers the siting criteria established by the worlds leading countries in high-level radioactive waste disposal with the aims of establishing detailed criteria appropriate to Korea's conditions and applying the criteria to explore safe and suitable sites for deep geological disposal. The findings of this research are expected to serve as a foundation for establishing criteria for the selection of disposal sites for high-level radioactive waste in Korea and are anticipated to contribute significantly to sustainable national development and environmental protection.

This study was carried out to observe the property changes of radishes salted with different salt (deep sea water and sun-dried salt). Shrinkage rate, salinity and texture were measured. The shrinkage rate values of radishes salted with deep seawater salt solution were higher than those salted with sun-dried salt in 8 hr after salting. The salinity of radishes salted with deep seawater salt solution was also higher than those salted with sun-dried salt. The jelly strength decreased during salting period and 5％ salting radish were lower than 3％ ones. The softness and hardness of radishes salted with deep seawater salt were higher than those salted with sun-dired salt as well.

The purpose of this study is to examine the effects of compassion experienced by defectors on deep acting in organization and secondly to demonstrate the effect of deep acting through compassion on job performance. Third, the purpose of this study is to examine the effects of deep acting on organizational citizenship behavior. Fourth, we examine the mediating effect of deep acting in the relationship between compassion and job performance. Finally, we try to demonstrate the mediating effect of deep acting in the relationship between compassion and organizational citizenship behavior. As a result of this study, it was proved that compassion experienced by defectors has a positive effect on deep acting and that deep acting has a positive effect on job performance and organizational citizenship behavior. In addition, all hypotheses were supported by the findings of research on the mediating effect of deep acting in the relationship between compassion and job performance, and compassion and organizational citizenship behavior. Thus, this study implies that the defectors who need compassion in the organization improve their job performance and increase organizational citizenship behavior through deep acting.

재료공학에서 머신러닝을 이용해 목적 성능에 부합하는 물질의 조성을 탐색하는 연구가 있다. 물질의 성능은밀도 범함수 계산을 통해 시뮬레이션 할 수 있지만, 계산량이 많은 문제가 있다. 본 연구를 통해 우리는 고효율 페로브스카이트 태양광전지를 만들기 위한 페로브스카이트 조성을 추천하는 심층신경망과 베이지안 최적화 모델을 제안했다. 본 연구에서 높은 전력효율이 예상되는 페로브스카이트 조성을 심층신경망과 베이지안 최적화 방법을 통해 추천하는 모델을 구현하였다. 심층신경망 모델은 주어진 조성과 실험조건에서 예상되는 전력효율을 예측해 베이지안 최적화를 통한 탐색과정에서 소요되는 실험비용을 줄인다. 베이지안 최적화 모델은 실험공간을 입력으로 받아 고효율이 예상되는 실험조건을 출력하는데, 미리 설정한 실험공간만을 탐색하기 때문에 실험적으로 가능한 출력값만을 제시 할 수 있다. 본 연구는 심층신경망과 베이지안 최적화 방법을 조합해 주어진 실험공간을 탐색하는 시간과 비용을 최소화하는 방법을 제시한다

최근 비전통적 성인 학습자가 새로운 입학자원으로 주목받고 있으며, 그중에서도 만학도의 대학 진학률은 급격히 상승하는 추세다. 이에 따라 이들이 대학생활을 무사히 마칠 수 있도록, 즉 학업중단이 발생하지 않도록 대학에서는 다양한 측면에서 방안을 골몰해야 하는 상황이다. 본 연구는 이러한 문제의식에 기반하여, 비전통적 학습자의 학업중단을 저지할 방안을 창업지원 측면에서 살펴보고자 하였다. 이는 학업능력, 성별, 교우관계 등을 중점적으로 살펴보는 기존 연구에서 더 나아가 창업지원이라는 새로운 요인과의 관계성을 만학도의 입장에서 심층적으로 살펴봄으로써 연구의 차별성을 강조한다. 본 연구는 대학 입학 이후 학교의 창업지원을 받은 경험이 있는 만 30세 이상의 만학도 총 10명을 대상으로 심층인터뷰를 진행하여, 학교의 창업지원이 학업중단을 저지하는 데 영향을 주었는지를 살펴보고자 한다. 또한 그 과정에서 이들이 느낀 감정과 태도, 가치 등을 근거이론을 통해 분석하여 학업중단을 저지할 방안을 모색하고자 한다. 만학도는 전통적 학습자와 달리 졸업 이후 인생2모작을 준비하는 경우가 상당수기에, 이들의 니즈를 명확하게 파악하는 일은 시대적 흐름을 반영한 기초연구로서 학교의 정책적 대안을 마련하기 위한 기반이 될 수 있다.

Japan enacted the "Designated Radioactive Waste Final Disposal Act" for the geological disposal of high-level radioactive waste in 2000 and began the site selection process. However, no local government wanted to participate in the siting process. Therefore, in 2015, the Japanese government developed a new site selection process during the literature survey step, and on June 28, 2017 they published a "Nationwide Map of Scientific Features for Geological Disposal" created with the aim of promoting public participation from local governments. This map illustrated the requirements and criteria to be considered in the early or conceptual stages of securing a geological repository and was useful for improving public understanding and exchanging opinions with local governments by analyzing the suitability of different geological disposal sites.

Changes in media technolgy affect the competitive status of broadcasting networks as news media. The competitive media environment has pushed broadcasting network news programs to find new ways for leveling their qualitative performance up and rating. This study focuses on the empirical relationship between the two key value, news quality in terms of fairness and in-depthness and news ratings. This study is based on the analysis of broadcasting network news texts and individual news item raitngs. Empirical relationship between news quality factors and ratings was proved positive. But the relationship between the length of news item and rating was proved negative.

${Cachin}^{[1]}$ defined the security of steganography theoretically at first, then ${Katzenbeisser}^{[2]}$ and ${Hopper}^{[3]}$ also discussed it on the different aspects. Unfortunately, because many steganographic systems couldnt overcome the statistical gap between a stego-cover and a pure cover, the secure steganography hasn' been evaluated yet. By the effectivel steganalysis algorithm, statistical test which was suggested by Westfel $d^{［4］}$, the attacker Wendy could select the stego-covers out of suspicious covers. Our newly developed algorithm which minimizes the changes of a pure cover by using the block cipher withstands a statistical test and has a similar embedding capacity in comparison with a simple LSB substitution steganography.
