This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

Cyclic Loading Test of Structural Walls with Small Openings

Hyun-Jin Yu,Su-Min Kang,Hong-Gun Park,정란 한국콘크리트학회 2019 International Journal of Concrete Structures and M Vol.13 No.6

This study aimed to investigate the effects of small openings on the structural performance of reinforced-concrete(RC) structural walls. Cyclic lateral loading tests were conducted on five RC walls with an aspect ratio of 2.6 and small openings. The main test parameter was the size of the small openings. The specimens were designed to fail after flexural yielding, considering the typical failure mode of slender RC walls. The structural performances of the test specimens were analyzed based on the test results in terms of the load-carrying capacity (flexural strength), hysteretic behavior, strain distribution, and the size of the openings. The specimens showed flexural yielding regardless of the size of the openings, and the flexural strength and deformation capacity were not significantly affected by the small openings. This result indicates that small openings do not affect the flexural behavior of slender walls if the walls have sufficient shear resistance and the small openings are located away from the extreme compressive end and in the compression zone where compressive stress does not decrease.

이 연구는 트레드밀 운동과 키네시오 테이핑의 효과에 따른 폐활량의 변화를 알아보기 위해 26명의 비흡연자가 참가하였으며 키네시오 테이핑을 적용하지 않은 그룹과 키네시오 테이핑을 적용한 두 그룹으로 무작위로 배정하고 각 군들을 주 3회 6주간의 트레드밀 훈련을 실시하였다. 실험 전과 후, 스파이로미터를 사용하여 키네시오 테이핑의 적용 따른 폐활량 변화 효과를 측정하였다. 이 연구의 결과를 종합해보면 키네시오 테이핑을 적용 그룹에서 적용하지 않은 그룹에 비해 FVC, FEV1에서 유의한 증가를 보였다. 이러한 결과는 건강한 성인에서 키네시오 테이핑을 적용한 경우 키네시오 테이핑을 적용하지 않고 트레드밀 운동을 한 경우보다 폐활량의 향상에 효과적이라고 생각되어진다. The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of kinesio taping with treadmill exercise. Twenty-six non-smokers were participated in this research and these subjects were randomly assigned into two groups. To measure the VC variation effects of kinesio taping, spirometer was used. The collected data were analyzed statistically by using a paired Mauchly test and repeated measure ANOVA. The results of this study were as follows; A group: treadmill with kinesio taping B group: treadmill without kinesio taping. Between A and B, there were significant differences. In the case of A group, there was 11.66% increase of VC, during 3 weeks experiment(p<.01). In the case of B group, there were significant differences, 3.35% increase of VC, during 3 weeks taping intervention(p<.01). After 6 weeks experiment, the improvement of VC shown a significant difference with intergroup (p<.05). From this result, it was revealed that treadmill exercise with kinesio taping was effective to improve VC to healthy adult than treadmill exercise without kinesio taping.

거주자 참여의 도시형 집합주택의 적용 가능성에 관한 연구

진수용,김현주,이상호 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(계획계)

Recently, as housing supply is going on too high-rise apartment, it's pointed out an urban environment is not a variety of forms. The purpose of this research is to propose the new methods of supplying an urban co-operative housing premising that the common house of the city is not an ordinary collective housing like the present but a form that accepts a variety of life of residents. The applying probability of co-op housing is investigated by using a questionnaire whether house demanders satisfy themselves or not and the rest of researching contents quotes from data recorded a thesis, statistical data and periodicals by documentary research. As the results of a questionnaire, it was evaluated that 75 percents of respondent had affirmative opinions. If co-operative housing is bring in our country, it is expected that it can alternate potential demand successfully which is not equal to the existing task.

본고는 일제 강점기 조사 미등록 유물 정리사업의 일환으로 수행한 평양 남정리 53호분 출토 토제칠이배, 토제칠반, 토제칠안에 관한 연구이다. 남정리 출토 유물은 소지가 목심이 아닌 토제라는 것과 칠이배와 칠반을 얹은 칠안이 함께 출토되었다는 점에서 주목할 만하다. 토제칠이배 및 칠반 그리고 칠안의 보존처리를 통해 이들의 형태와 문양 등에 대해 알 수 있었다. 또한 칠기에 사용된 붉은색 안료의 성분을 분석하여 안료의 주성분이 진사(HgS)였음을 확인하였다. 이번 연구에서 기존에 잘 알려지지 않았던 한반도 내 위치한 낙랑의 토제칠기에 관해 살펴볼 수 있었으며 이러한 제작방법이 한나라 고유의 문화인지 아니면 재지세력이 한나라의 영향을 받아 현지화한 문화의 산물인지에 대해 생각해 볼 수 있는 기회라 생각된다. This research paper examines the lacquered pottery cup, plate and table unearthed from Tomb No. 53 at Namjeong-ri in Pyongyang, which were under conservation treatment as a part of the Project of Unregistered Artefacts Uncovered in the Japanese Colonial Era. It is very rare to have a lacquered pottery cup and plate, lying on a lacquered pottery table, as a set of grave goods. In particular, they are not wooden but pottery items. Through conservation treatment for lacquered pottery cup, plate and table, it was possible to find out their shapes and decoration patterns. The resulting analysis of the red pigment used indicates that cinnabar (HgS) is the main element. This research is significant because it examines lacquered pottery wares produced in Lelang, which has rarely been conducted. Further research will need to prove whether their production techniques were in the unique Chinese Han style or were produced by indigenous craftsmen who adopted the Chinese Han technique.

To develop artificial matrix resorbable by osteoclasts can be used as a model system that biological function of osteoclasts would be assayed in vitro in a standardized condition instead of using heterogenous bone or dentin slices. The present study developed artificial substrates consisted of apatite crystals. collagen gen. agar, apatite crystals under collagen film, mixture of apatite crystals and collagen, and mixture of agar and apatite crystals. And osteoclastic attachement and resorption activity on the each substrate was assayed in vitro. Osteoclasts attached to apatite crystals, collagen, mixture of apatite crystals and collagen, and mixture of apatite crystals and agar, however, not to agar. This suggested that apatite crystals and collagen should be exposed on the surface of artificial substrate where osteoclasts can attach. Osteoclasts attached to the substrate resorbed the substrate consisted of apatite crystals, mixture of apatite crysals and collagen, and apatite crystals under thin film of collagen, however, not of collagen, mixture of apatite crystals and agar. This suggested that the first phase of osteoclasts in resorbing matrix is to secrete acid and the end result of this phase, whatever it may be, may activate secretion of hydrolytic enzymes specific to organic components.
