The author investigated the history of oyster culture in Korea through examining old books and reports dealing with the fishery. Oysters have been produced in the all coastal areas in Korea, especially the center areas of production were the Hwangupo(Hamkyongbuk-do), Younghungman(Hamkyongnam-do), the estuary of Nakdonggang(Kyongsangnam-do), Kwangyangman, Haechangman, the estuary of Yongsangang(Chollanam-do), Yonghoto(Hwanghae-do) and the estuary of Uprockgang, where the large size oyster (more than 40㎝ in shell height) inhabited in form of groups. It was called by nine different names in the old times, Gul, Seukhwa and Moryeo were the most common names. The oyster was used as 46 kinds of medicinal stuff. The habitat forms of natural oyster can be distinguished to two types; one is that oyster is exposed to the air during the period of low tide(A-type), another is that oyster is not(B-type). The first oyster culture by the old books in Korea was started about 530 years ago as the bottom culture method derived from the A-type of oyster. After long years, the hanging culture method might have been started from the hint of the habitat form of B-type. The oyster culture in Korea developed based on the habitat forms of natural oyster at the beginning of 1900s. After World War II, the Korean government strongly recommded the layer farmers to culture oyster as relief measures. At that time, the stone culture method was mainly adopted. The quantity of oyster production is now about 15×10^6-19×10^6 M/T, and the half of oyster production including seed oyster is exported to the foreign countries.

We studied on the problems and improvement of present curriculums of 8 fisheries high schools in Korea to help make a new curriculum in the future. The results are as follows. 1.A technical teacher teaches the mean 18.2 school hours more 2-6 than Japanese teacher a week. It is desirable to decrease the school hours of technical subjects in order to increase those of cultural studies. 2.The component ratio of technical and cultural school hours is 60 to 40 in Korea and 50 to 50 in Japan. It is desirable to change the component ratio of subjects at the ratio of 50 to 50 through the unification or abolition of a par of subjects so that the students can be educated to fit for the rapid change of social life. 3.The possession rate of experimental instruments is 50% under the standard amount. It is required to get all the necessary instruments so that all experiment and practice can be carried out normally.

The purpose of this study is to understand for the experiential emotion of elementary school students underwent lessons in each area of Physical activity and what factors affecting them are. Participant observation, in-depth interviews and documentation review were used. The result is as follows. With respect to a positively emotional experience in health activities, while boys think of ‘growing strength by doing games' as a positively emotional experience, girls think of ‘confidence in sports ability' as a positively emotional experience, regarding a negatively emotional experience, boys and girls think of ‘boredom of static activity' and ‘fatigue' as a avoidance factor respectively. As a positively emotional experience in challenge activity, boys and girls regard ‘competition and fighting spirit' and ‘successful experience' as a positively emotional experience, respectively, as to a negatively emotional experience, boys and girls think of ‘lack of balance' and ‘injury' as a negatively emotional experience. Pertaining to a positively emotional experience in competition activity, boys and girls consider ‘experience of victory' and ‘weird experience' as a interesting factor, respectively, as for a negatively emotional experience, boys and girls think of ‘unequal roles' and ‘excessive competition' as a negatively emotional experience. In regard to a positively emotional experience in expression activity, boys and girls count on ‘not constrained' and ‘conversion to joyful atmosphere' as a positively emotional experience, respectively, as with a negatively emotional experience, boys and girls think of ‘lack of rhythm' and ‘expressive ability' as a negatively emotional experience, respectively. 이 연구의 목적은 초등학생들이 체육수업에서 체험한 정서 요인이 무엇인지 이해하는 데 있다. 참여관찰, 심층면접, 문서자료 검토 등을 사용을 통해 개인별로 사례기록을 작성한 후 단위화와 부호화 작업을 하였다. 연구 문제에 적합한 주제를 도출하기 위해 Spradley(1980)의 귀납적 범주 분석 방법을 이용해 분석하였다. 다각도 접근법과 구성원 간 검토, 동료 간 협의를 실행하여 다음과 같은 결과를 얻었다. 긍정적 정서 요인으로 남학생들은 ‘게임하며 근력 기르기’, ‘경쟁과 승부욕’, ‘승리 경험’, ‘구속되지 않음’을 제시하였고, 여학생들은 ‘운동기능에 대한 자신감’, ‘성공 경험’, ‘별난 체험’, ‘즐거운 분위기 전환’을 주요한 원인으로 제시하였다. 또 부정적 정서 요인으로 남학생들은 ‘정적 활동의 지루함’, ‘균형 감각 부족’, ‘불평등한 역할 분담’, ‘리듬감 부족’을 제시하였고, 여학생들은 ‘피로’, ‘부상’, ‘지나친 경쟁’, ‘표현 능력 부족’을 제시하였다. 이상의 내용을 종합해 보면 남학생들은 주로 경쟁적이고 도전 과제가 있는 활동에서, 여학생들은 스스로 창의적으로 발산할 수 있는 활동에서 긍정적 정서를 경험하였다. 또, 남학생들은 정적인 동작으로 이루어진 무용과 같은 활동에서, 여학생들은 부상의 위험이 있거나 친구들의 시선을 의식해야 하는 활동에서 부정적 정서를 경험하였다.

Layer is sea weeds that might have been eaten by Korean people since ancient times. The beginning of layer culture is not known exactly, but it appears to be prehistoric age. Some layer culture complexes have been built in southern coastal sea of Korea around 1910. This paper was considered about the origin and development process of Korean layer culture industry by investigating Korean and Asian old books concerned. The results are as follows. 1. According to the Korean old books related, the name of layer is classified into 10 kinds. Gim and Hae-I were called by Korean. Gim means weeds and Hae-I means the manufactured layer by cutting and drying like paper sheet. Ja-Chae and Hae-Tae are come from Chinese, however they are commonly called by Korean, Japanese and Chinese. Rest six names are come from Chinese botany. 2. As Chinese used layer as medicine for wen, scrofula, fever, vomiting, diarrhoea and so on, they didn't regard it as foods and took into account an warning by Chinese botany that they could take ill when overeating it. On the other as Korean people have eaten it with pleasure nevertheless the Chinese warning, various foods using layer have been developed. The typical food is rice covering layer sheet. It is also popular to Japanese. 3. Layer culture can be carried out in all coastal seas around Korean peninsula, the best sea area for it is the middle west of south sea. 4. Seopkkoji type is a layer culture method that when branches of tree are put in tidal flat layer sporules are attached and grown on them. It was begun by Hae-Jak Kun(a group of fishery slaves) on Kwang-Yang bay the most suitable for layer growth at the beginning of King Sung-Jong(1469-1481). It is assumed that when Hae-Jak Kun set Oe-Jeon(a sort of fixing fishing gear) to catch tributary fish for king, they could find grown layer attached on Oe-Jeon and invent Seopkkoji type for exclusive layer culture. That was carried out 200 years earlier than in Japan. Dde-Bal type is more advanced and productive layer culture method with thinly spilt bamboo tied like screen(one end fixed on bottom and other end set free in water). It is assumed that Dde-Bal type was begun in Wan-Do county in King Chull-Jong (1830). All layer culture methods developed were transfered to Japan.

Currently, numerous companies and institutes provide services using the Internet, and establish and operate Information Systems to manage them efficiently and reliably. The Information System implies the possibility of losing the ability to provide normal services due to a disaster or disability. It is preparing for this by utilizing a disaster recovery system. However, existing disaster recovery systems cannot perform normal recovery if files for system recovery are corrupted. In this paper, we proposed a system that can verify the integrity of the system recovery file and proceed with recovery by utilizing hyper-ledger fabric blockchain. The PBFT consensus algorithm is used to generate the blocks and is performed by the leader node of the blockchain network. In the event of failure, verify the integrity of the recovery file by comparing the hash value of the recovery file with the hash value in the blockchain and proceed with recovery. For the evaluation of proposed techniques, a comparative analysis was conducted based on four items: existing system recovery techniques and data consistency, able to data retention, recovery file integrity, and using the proposed technique, the amount of traffic generated was analyzed to determine whether it was actually applicable. 오늘날 수많은 기업과 기관들은 인터넷을 사용한 서비스를 제공하고 있으며, 이를 효율적이고 안정적으로 관리할 수 있도록 정보시스템을 구축하고 운영한다. 정보시스템은 재해 또는 장애로 인해 정상적인 서비스를 제공 할 수 있는 기능을 손실할 가능성을 내포하고 있다. 이에 재해복구시스템을 활용하여 이를 대비하고 있다. 그러나 기존의 재해 복구시스템은 시스템 복구를 위한 파일이 손상되는 경우 정상적으로 복구를 수행할 수 없다. 이에 본 논문에서는 하이퍼레저 패브릭 블록체인을 활용하여 시스템 복구 파일의 무결성을 검증하고 복구를 진행할 수 있는 시스템을 제안한다. 블록 생성을 위하여 PBFT 합의 알고리즘을 사용하며, 블록체인 네트워크의 리더 노드에 의해 수행된다. 장애 상황 발생 시 복구 대상의 복구 파일의 해시 값을 블록체인 내의 해시 값과 비교하는 검증 작업을 거쳐 복구 파일의 무결성을 확인하고 복구를 진행한다. 제안 기법의 평가를 위하여 기존의 시스템 복구기법과 데이터 정합성, 데이터 보존 여부, 복구 파일 무결성 검증, 제안 기법 사용 시 트래픽 발생량을 분석하여 실제 적용 가능 여부를 확인하였다.
