Plasma levels of liporoteins were observed in vegetarians and non-vegetarians in order to compare the values between the two groups with different dietary habits, and among different age groups. All 162 vegetarians and 95 non-vegetarians were selected for this study. In detail, male vegetarians subjects were devided into three groups according to their ages, 20's, 30's and 40's. And three control groups were also selected at matching basis. Two groups each were selected for female subjects in their 20's and 40's. All ten groups were adopted and the lipids levels were compared appropriately. Plasma pre-β-lioprotein levels of non-vegetarians were not significantly in all groups. And plama α-liporotein levels of non-vegetarians were higher than the ones for vegetarians as compared with male of 20's, male 30's female of 40's, and it was not significantly as compared with female of 20's. And plasma β-liporotein levels of vegetarians were significantly lower than the ones for non-vegetarians in all groups. Most of plasma liporotein levels measured were found to be lower in vegetarians and tended to be higher age proups of both vegetarians and non-vegetarians. Ans plasma α-lipoprotein levels which is known to be adversely related to atheroscherosis were higher in non-vegetarians, it can be concluded in this study that the plasma lipoprotein levels of non-vegetarians under Korean dietary patterns are quite acceptable.

Viral hepatitis may injure the central and peripheral nervous system, resulting in encephalitis, meningitis, myelitis, isolated pyramidal or extrapyramidal tract dysfunction, seizures, mononeuritis, plexitis, and psychiatric disturbances. Hepatitis associated Guillain-Barr syndrome mostly occurs as a complication of acute hepatitis, but is caused rarely by chronic active hepatitis B. Usually, Guillain-Barr syndrome is associated with peripheral nervous dysfunction and rarely involve central nervous system. However, Guillain-Barr syndrome with the 6th cranial nerve palsy resulted from chronic active hepatitis B is extremly rare. Recently, we experienced the case of Guillain-Barr syndrome with the 6th cranial nerve palsy in 21-year-old man with chronic active hepatitis B. He was improved with interferon-α2b and ordinary conservative treatment. Here, we report a rare clinical case of Guillain- Barr syndrome with the 6th cranial nerve palsy complicated by chronic active hepatitis B with a review of literatues.

對宋 외교 활동에 참여한 고려 수군 - 『破閑集』과 『高麗圖經』에 나타나는 사례를 중심으로

이창섭 고려대학교 역사연구소 2014 사총 Vol.83 No.-

Goryeo Navy performed various duties in addition to battle. It was confirmed that Goryeo Navy was accompanied by envoy’s maritime journey through Yi Ja-Yeon(李子淵)’s records of envoy’s journey to Chinese Sung Dynasty described in Pahanjip(破閑集, which means a book breaking idle hours; Goryeo book of poetry and tales written by Yi Il-Lo(李仁老)). The Navy was responsible for sailing and the safety of delegation in case of emergency, and secretly collected the information after arriving at the Sung. At that time, the Navy who went there had major duties of sailing and the performance of ceremony. Diplomacy was done at the level of central government and the envoy and entourage were representative of Goryeo after visiting foreign countries. Thus, Goryeo intended to reinforce high-ranking soldiers with professionalism if soldiers were required in the envoy’s journey to the Sung. Consequently, the Navy belonging to the Central Command was mobilized. There were naval forces called Naval Command(海領, Haeryeong) in charge of maritime ceremony under the command of Cheonu Guard(千牛衛) in the Goryeo Central Command. In this respect, the Navy who got involved in diplomatic visit by sea route belonged to the Naval Forces Central Command. Goryeo Navy was mobilized when greeting envoy from the Sung as well as when accompanying Goryeo’s envoy visiting the Sung. The mobilized Navy also belonged to the Naval Command. When the envoy of the Sung visited Goryeo, Goryeo had to pay careful attention to many things in terms of protocol, and the Naval Command in charge of ceremony was suitable for the performance of such a duty. The Navy mobilized to greet the envoy and delegation from the Sung drove a ship carrying government officials greeting them in Goryeo. And it performed ceremonies at the major stopping points such as Koonsando Island, Mado Island and Jayeondo Island during journey with the envoy and delegation after meeting them. Goryeo Navy made contributions to the exchange between Goryeo and the Sung in various ways by implementing many duties when dispatching envoy and delegation to the Sung and performing ceremonies related with the reception when greeting envoy and delegation from the Sung. 고려 시기의 수군은 전투 외에도 다양한 임무를 수행하였다. 이 글에서는 『破閑集』에 나타나는 李子淵의 宋 使行 기록을 통해, 海路를 이용한 使行에 고려 수군이 동행하고 있음을 확인하였다. 수군은 운항을 담당하고, 유사시에는 사절단의 안전도 책임졌으며, 송에 도착해서는 현지의 정보를 수집하였다. 이때 송에 간 수군은 운항과 의례 수행을 주요한 임무로 하였다. 외교는 중앙 정부 차원에서 이루어지는 활동이고, 수행원들은 외국에 나가서 고려를 대표하는 사람이었다. 그런 까닭에 고려에서는 使行에 군인이 필요한 경우 지위가 높고 전문성을 갖춘 이들을 뽑아 파견하고자 하였다. 해로로 사신을 파견할 때에는 이같은 조건을 충족시키는 중앙군 소속의 수군을 동원하였는데, 고려 중앙군에는 의례를 담당하는 千牛衛 휘하에 해상에서의 의례를 맡는 海領이라는 수군 부대가 있었다. 이런 면에서 볼 때 해로를 이용한 외교에 참여한 수군은 중앙군인 천우위 해령에 소속된 군인이었다. 고려 수군은 송에 가는 사신을 수행할 뿐 아니라 반대로 송에서 온 사신을 고려에서 맞이할 때에도 동원되었다. 이때의 수군 또한 해령 소속이었다. 송 사신이 고려에 올 때에는 儀典이라는 측면에서 고려가 세심하게 신경써야 할 부분이 많았는데, 의례를 담당했던 해령은 그러한 임무 수행에 적합하였다. 송 사절 영접에 투입된 수군은 고려에서 영접하는 관원들의 배를 운항하였고, 송 사절과 조우한 뒤에는 그들과 여정을 함께 하면서 群山島, 馬島, 紫燕島 등 주요 거점에서 의례를 행하였다. 고려 수군은 고려에서 송으로 사신을 보낼 때에 이를 수행하며 다양한 임무를 수행하고, 송 사신이 고려에 올 때에는 이들에 대한 영접 관련 의례 등을 담당함으로써 麗宋 교류의 현장에서 여러모로 기여하였다.

Protein bodies in the endosperm cells of mature red ginseng (Panax ginseng C.A. Meyer) were distributed evenly in the cytoplasm and their size varied from 1 to $8{\mu}m$. Three types of protein bodies were detected and they are spherical or egg-shaped ones containing homogeneous matrix only, spherical ones containing globoids, and irregular shaped ones. Protein bodies degraded in two patterns, one is to start the degration of the body from the surface toward the center, while the other is that the body was broken evenly and then degraded gradually. After degradation, only the limiting membrane remained, that causes the body to be empty. The limiting membranes fused with each other to form a large vacuole. Vicilin and legumin decreased in the endosperm cells as the protein bodies degraded gradually whereas they increased in the umbiliform layers.

코로나19에 따른 국내 제약회사의 하방경직적 원가행태 변화

이창섭,우소희 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.1

본 연구는 2018년부터 2021년 국내 유가증권에 상장된 제약회사를 대상으로 코로나19가 판매관리비의 하방경직적 원가행태에 미치는 영향을 실증적으로 분석하였다. 원가의 하방경직성은 기업의 매출이 증가할 때의 원가 증가 수준보다 매출이 감소할 때의 원가 감소 수준이 낮은 것을 의미하며, 이는 경영자의 조정비용을 고려한 의사결정으로 발생한다. 코로나19 확산 이후 국내 제약회사의 경우, 한정된 자원을 신약 연구개발 및 코로나 관련 상품의 수입 등에 집중해야 하며, 매출의 장기적 감소가 예상되는 상황을 대면하였다. 본 연구에서는 이와 같은 상황에서 경영자는 판매관리비를 코로나 19 확산 이전보다 적극적으로 절감하는 효율적 의사결정을 수행하여 원가의 하방경직성이 완화될 것으로 예측하였다. 실증검증을 위해 Anderson et al.(2003)의 모형을 사용하였으며 실증분석 결과, 코로나 19 팬데믹 이후 판매관리비의 하방경직성이 코로나 19 이전에 비해 완화되었음이 관찰되었다. 본 연구결과는 코로나19가 경영자의 판매관리비에 관련된 의사결정에 유의한 영향을 줄 수 있음을 제시함으로써, 관련 실무자 및 학계에 기여할 수 있을 것으로 기대된다.
