최영준,이영화,최재홍,Choe, Young June,Lee, Young Hwa,Choi, Jae Hong 대한소아감염학회 2022 Pediatric Infection and Vaccine Vol.29 No.1

Purpose: During the coronavirus disease 2019 (COVID-19) pandemic, we conducted a Delphi survey that included the experts from the field of COVID-19 immunization in children aged 5-11 years. The aim was to organize collective expert opinions on COVID-19 vaccination in young children in the Republic of Korea, and so thus assist the vaccination policy. Methods: The panels included pediatric infectious disease specialists, preventive medicine experts, infectious disease physicians, and COVID-19 vaccine experts consulting the Ministry of Health and Welfare. The Delphi survey was conducted online using a questionnaire from February 14 to February 27, 2022. Results: The Delphi panels agreed that children were vulnerable to COVID-19, and the severity of illness was modest. Furthermore the panels reported that children with chronic illness were more susceptible to a worsening clinical course. There were generally positive opinions on the effectiveness of COVID-19 vaccination in children aged 5-11 years, and experts gathered a slightly positive opinion that the adverse events of pediatric COVID-19 were not numerous. The benefits of COVID-19 vaccination were evaluated at a level similar to the potential risks in children. Currently, the only approved mRNA platform vaccine in children seemed to be sustainable; however, the recombinant protein platform COVID-19 vaccines were evaluated as better options. Conclusions: Due to the surge of the Omicron variant and an increase in pediatric cases, the COVID-19 vaccination in young children may have to be considered. Panels had neutral opinions regarding the COVID-19 vaccination in children aged 5-11 years. Thus monitoring of the epidemiology and the data about the safety of COVID-19 vaccination should be continued.

최영준,강석중,조창환,명정구,김종현,Choi Yeung Joan,Kang Seok-Joong,Cho Chang-Hwan,Myoung Jung-Goo,Kim Jong-Hyun 한국양식학회 1990 韓國養殖學會誌 Vol.3 No.2

멜라닌 색소의 생합성 과정에 관여하는 것으로 알려져 있는 효소 및 관련 인자와의 상관성을 검토하기 위하여 자연산 정상넙치와 양식산 백화넙치의 육질과 표피, 미립자 사료와 생물먹이인 Artemia 및 Rotifer에 대하여 단백질의 함량, 멜라닌 색소생성에 관여하는 효소의 활성, 아미노산 조성 및 비타민A와 C의 함량을 비교하였다. 정상넙치표피는 육질에 비하여 단백질의 함량이 높았으나, 백화넙치인 경우는 대체로 비슷한 값이었다. 사료중의 단백질 함량은 미립자 사료 중 Cl이 가장 높았다. catechal oxidase의 활성은 기질과 조효소 농도의 증가와 더불어 증가하였으며, 백화 유무에 관계없이 거의 유사한 값으로 나타났다. 그리고 L-dopa oxidase활성도 동일한 결과였다. 정상넙치의 유리아미노산 함량은 백화개체에 비하여 높았으며, 표피의 경우는 정상넙치가 백화넙치에 비하여 7.5배 가량 높은 값을 나타내었다. 필수아미노산의 조성으로 비교했을 때, 미립자 사료는 Artemia와 Rotifer보다 우수한 단백질원이었다. 그리고 정상넙치의 함황아미노산의 함유량은 백화넙치의 6.3배에 달하였다. 비타민A는 정상 및 백화넙치의 육질과 표피에서 검출되지 않았으나 비타민C는 정상인 넙치표피가 백화넙치 표피에 비해 약 7.8배였으며, 미립자 사료는 100.83mg/100g으로서 사료 중 가장 높았다. 따라서 넙치표피의 멜라닌색소의 생성에는 기질인 방향족 아미노산과 함황아미노산이 큰 영향을 미치는 것으로 판단되었다. The albinic phenomenon of flat-fish (Paralichthys olivaceus) was investigated by measuring protein content, tyrosinase activity, amino acid composition, and contents of vitamin A and C. These materials in the flat-fish feed-stuff were also tested. The amount of skin protein was higher than that of muscle in normal flat-fish. Catechol and L-dopa oxidase activity did not differ between normal and albinic flat-fish. The free amino acid of skin in normal flat-fish was 7.5 times that in albinic one. Sulfur-containing amino acid in normal flat-fish was also 6.3 times that in albinic ones. Vitamin A was not detected in both of flat-fish. The content of vitamin C in normal flat-fish was 7.8 times that in albinic one. The contents of protein, sulfur-containing amino acid and vitamin C in micro-encapsulated feed (one commercial feed in Japan) were the highest among the feed-stuff used in this experiment. The melanin formation of flat-fish skin was affected by substrates such as aromatic amino acid and cofactor such as sulfur amino acid.

The deployable space structure is necessary to minimize the satellite volume and launch cost. For the deployment, passive deployment mechanism has widely been used to attenuate a latch shock induced when the structure is just fully deployed. To reduce the latch shock, viscous damper is applied to the passive deployment mechanism and it can control the deployment speed of the structure. In this paper, dynamic analysis of the deployable space structure using the passive deployment mechanism with the viscous damper has been performed. The viscous damping values have been optimized through numerical simulation. The satellite's attitude influenced by pyro activation for the release of the structure has also been investigated.

This study was carried out to investigate the effects of dandelion leaf, root and whole part extracts on the physicochemical characteristics of pork patties stored at $4^{\circ}C$ for 10 days. Four types of pork patties were evaluated: ice-water-added (T0), dandelion leaf extract (T1), dandelion root extract (T2) and dandelion whole part extract (T3). The pH decreased significantly during storage, but increased after 10 days of storage. The pH was highest in T0 during storage. The L value of T0 increased whereas T1, T2 and T3 did not significantly changed during storage. The a value decreased with a longer storage period, and the a values for T1, T2 and T3 were higher than that of T0 during storage. The b value did not change significantly during storage. The TBARS increased with a longer storage period, and the values for T0, T1, T2 and T3 were 0.87, 0.29, 0.47 and 0.31 mg MA/kg, respectively, after 10 days of storage. The VBN content value of T0 increased, but those of T1, T2 and T3 did not significantly change during storage. The water holding capacity of T0 decreased, but those of T1, T2 and T3 did not significantly change during storage. Cooking loss increased during storage and that of T0 was higher than those of T1, T2 and T3. Hardness and chewiness decreased while springiness and cohesiveness increased during storage.

최영준,김세환,임영선,김인수,김동수,조영제,CHOI Young Joon,KIM Se-Hwan,IM Yeong-Sun,Kim In-Soo,KIM Dong-Su,CHO Young-Je 한국수산과학회 1998 한국수산과학회지 Vol.31 No.3

액젓의 객관적인 품질평가 기준을 설정하기 위하여, 전통적인 방법에 따라 발효 숙성시킨 멸치 액젓과 시판 멸치 액젓의 일반성분, 총질소량, 아미노산 함량, SDS-PAG전기영동을 통한 특정 펩티드의 면적을 측정하였고, 아울러 액젓 원료어의 판정을 위해 등전점 전기영동을 시도하였다. 멸치 액젓의 수분 함량은 대조구가 가장 낮은 $60.5\%$였으며, 시판 제품은 $65.5\%\~69.2\%$로 큰 차이가 없었으나, 총질소 함량은 시판 제품간에 비교적 큰 차이를 보이고 있었다. 액젓에 잔존하는 단백질의 함량은 Y사의 제품이 비교적 높은 $0.353mg/m{\ell}$ 였으며, 나머지 시판 제품은 $0.093mg/m{\ell}\~0.293mg/m{\ell}$의 범위였다 한편 SDS-PAG 전기영동상에서는 J사를 제외한 모든 액젓 제품에서 분자량 55,600 및 46,900 dalton의 band가 검출되었으며, 전기영동상에 나타난 단백질 band는 제조회사에 관계없이 거의 비슷한 형태를 나타내고 있었다. 그리고 등전점 전기영동에서 멸치 액젓은 등전점 5.6에 해당하는 펩티드가 공통적으로 존재하며, 특징적인 band임을 확인하였다. 따라서 아미노산 및 저분자 질소 화합물의 첨가 여부가 정량적인 값에 영향을 미치지 않는 전기영동 상의 특정 band의 면적비를 측정함으로서 인위적인 질소화합물의 첨가, 액젓 희석 여부 판정이 가능 할 것으로 판단되었다. 그리고 전 질소 함량, 아미노산 함량 및 SDS-PAG 전기영동 상에 있는 특징적인 55,600 dalton에 해당하는 펩티드 면적비의 상관관계는 멸치 액젓의 품질판정을 위한 기준으로 활용 가능함을 제시하고 있다. An objective index for quality estimation of anchovy sauce, our traditional seafood, has been required because inadequate standard causes dispute about quality estimation. Qualities of anchovy sauce made by traditional method and commercial anchor sauce products were compared by investigating their proximate compositions, total nitrogen contents, amino acid contents, development and level of a specific peptide on SDS-polyacrylamde gel electrophoresis (SDS-PAGE) and isoelectric point (pI) of the specific peptide. Also, pIs of IEF were attemped to identify fish species of salt-fermented sauces. The 55,600 and 46,900 dalton of peptide band were identified in all experimental samples. Especially, the area of 55,600 dalton was closely correlated with total nitrogen contents. Also, specific pIs in accordance with fish species were identified. The results suggest that correlation between area of 55,600 dalton and total nitrogen contents are used of index for quality estimation, and specific pIs are used of fish species identification.

Logical Clock을 이용한 분산 시험

분산시스템(distributed system)을 시험할 때, 병렬 이벤트를(concurrent events)를 제어 할수 없다면 정확한 시험결과를 얻어내기 어렵다. 기존의분산 시험 방법은 정형적 방법으로 test sequence 생성 알고리즘을 제시하지 못하거나 동기화를 위한 부가적 메시지의양이 많은 단점이 있었다. 본 논문에서는 병렬 이벤트 제어를 위해 logical clock를 이용한 정형적 test sequence 생성 알고리즘을 제시한다. 이 알고리즘은 제어관철 문제를 해결하고 시험 결과를 재현할수 있다. 또한 어떠한 통신 패러다임에서도 적용될수 있는 일반적 해결방법을 제공한다. 분산 시험 방법에서는 분산 객체가 증가할수록 시험기 사이의 채널이 비선형(non-linearly)으로 증가하는 단점이 있다. 이 단점을 극복하고자 원격 시험방법(remote test method)의 시험 구조를 제안한다. 제안된 알고리즘의 검증을 위해 SDL 도구를 사용하고 Q.2971 망 부분(network side) 일대 다 호/연결 설정을 위한 메시지 교환에 적용한다. It is difficult to test a distributed system because of the task of controlling concurrent events,. Existing works do not propose the test sequence generation algorithm in a formal way and the amount of message is large due to synchronization. In this paper, we propose a formal test sequence generation algorithm using logical clock to control concurrent events. It can solve the control-observation problem and makes the test results reproducible. It also provides a generic solution such that the algorithm can be used for any possible communication paradigm. In distributed test, the number of channels among the testers increases non-linearly with the number of distributed objects. We propose a new remote test architecture for solving this problem. SDL Tool is used to verify the correctness of the proposed algorithm and it is applied to the message exchange for the establishment of Q.2971 point-to-multipoint call/connection as a case study.
