Orbtial myositis is an idiopathic, nonspecific inflammation of primarily one or more extraocular muscles and is considered as a subgroup of orbital pseudotumor. It can be distinguished as acute, subacute or chronic form. Acute orbital myositis is a single episode of orbital pain without fever lasting less than 6 weeks, whereas subacute or chronic form is a persistent episode lasting more than 2 months or with recurrence. The diagnosis is made by CT scan, ultrasonography or MRI, which is characterized by enlargement of extraocular muscle bellies and tendons. Although spontaneous resolution may be anticipated within 3 to 6 weeks, good treatment response is shown with corticosteroids. We recently experienced a case of orbital myositis in a 50 year-old female. She had bilateral orbital swelling 1 year prior to admission. Orbital swelling was relieved gradually but relapsed to show limitations of extraocular muscle movement. In orbit CT scan, there was diffuse thickening of eyeball muscle and swelling of facial subcutis. She was treated with methylprednisolone with marked clinical improvement after 4 days. After 1 month period of corticosteroid treatment, she had residual limitation of upward eyeball movement. We present this case with literature reviews.

The objective of this study is to empirically study the determinants of new product performance that influence on the performance of new product. The factors are the process of new product development, the company``s internal activities, cooperation among departments and external relationships with clients. In addition, Relationships with customer is included as the moderating variables between the performance of new products and primary factors. The performance was measured by the number of new product development cases and the degree to which a sales objective had been achieved. This empirical study could be summarized in two consequences. First of all, the variables that affected new product performance is the new product development process and the level of technology. Secondly, cooperation within the organization, characteristic of transactions and mutual trust with customers, which were significant in previous studies, did not have a direct effect on new product performance. As a result, a fact that the three factors have a effect indirectly on new product performance was investigated. As the moderating regression analysis(MRA) results, the characteristic of transactions with clients was investigated as adjusting variable that affects between the new product development process and the sales performance of new product. The differentiation of this paper is to verify determinants of new product performance including the factors that was consisted of a previous research. Most of the previous studies about causal relationship between the determinants of new product performance and the performance of a new product were conducted independently at different situations, according to purpose of investigation. A few variables that have a meaningful impact on performance in previous thesis did not have a effect partially on new product performance in this study. Like this, the reason that this research resulted different consequences from former research is to analyze comprehensively an object of study and survey data in multi regression, covering relationships between determinants of new product performance and performance of anew product.

It is said that Gwansanggam Jejo (觀象監提調) was in charge of running Gwansanggam (The Office for Observation of Natural Phenomenon) together with Yeongsa (領事). However, no research has been conducted on whether they were the practical managers of Gwansanggam. During the King Sukjong period, Gwansanggam Jejos were close to the ruling powers. Most of them were from Gyeonghwasajok (京華士族) and related to the family that produced people who served as Yeongsa and Gwansanggam Jejos, and some of them were related to the royal family. Based on their understanding of practical science, Gwansanggam Jejos managed business reports on astronomical observations and eclipses and supported the creation of astronomical instruments, almanacs and calendars. In geography, they participated in the practice of gansim (看審), bongsim (奉審) and repairing taebong (胎峯). In this way, they took on the role of practical managers for various astronomical and geographical tasks. In addition, they were in charge of gwageo (科擧), chwijae (取才), popyeom (褒貶), various personnel, awards, punishments, and coordination with other government offices. It is clear that they were active as managers in the process of playing this role. In conclusion, during the King Sukjong period, Gwansanggam Jejos acted as practical managers with the ability and qualities to understand Gwansanggam's work.

영조(英祖) 대 관상감(觀象監) 제조(提調)와 그들의 활동

신기철 ( Shin Ki-chul ) 한국과학사학회 2021 한국과학사학회지 Vol.43 No.3

Gwansanggam Jejo (觀象監提調) and Yeongsa (領事) were in charge of the operation of Gwansanggam (The office for Observation of Natural Phenomenon). During the reign of King Yeongjo, a tenure of Gwansanggam Jejo was shorter than that of King Sukjong’s mandate, and their appointment applied with Ssanggeohodaae (雙擧互對), method in which different party members were appointed to the positions of the two Jejo. However, during the reign of King Yeongjo, many Jejo were from the former Yeongsa and Jejo families. And the proportion of Jejo from the such family was higher than that of King Sukjong's reign. This situation is due to the implementation of Tangpyongchaek (蕩平策) allowed families, not mainstream forces, to participate in politics. During the reign of King Yeongjo, Gwansanggam Jejo was faithful to his role in maintaining and inheriting the existing regulations. At the same time, each of them played their role by revising various regulations in line with Almanac changes and changing the Gwansanggam organization and operating system accordingly. As a result, during the reign of King Yeongjo, Gwansanggam was able to implement a stable organizational system centered on astronomy.

중소기업을 위한 정책자금의 지원예산이 증가하면서 자원배분의 효율성에 대한 논의가 활발하게 이루어지고 있다. 이번 연구에서는 자원배분의 효율성 측면에서 중진공 평가기준을 통해 자금을 지원받은 기업이 꼭 받을만한 기업이었는지에 대한 타당성을 검증하고자 했다. 중소기업정책자금에 대한 정확한 대출의사 결정은 한정된 자원을 효율성 있게 배분하는 것은 물론, 적정기업을 선정하여 부실로 인한 기금의 손실을 최소화하기 위해서 필요한 연구이기 때문이다. 본 논문에서는 판별분석 및 로지스틱회귀분석을 통해 중소기업 정책자금 대출을 위한 의사결정에 대한 정확률을 추정하였다. 중소기업 정책자금 대출의사결정에 대한 정확률이 높은 것으로 검증되면 결과적으로 대출승인기업에 대한 자금지원도 효율적으로 이루어졌다고 볼 수 있기 때문이다. 판별분석 분류결과, 대출승인 예측업체를 대출승인업체로 정확하게 판별한 확률이92.87%로 나타났다. 로지스틱회귀분석에서는 전체적으로 대출승인 및 평가탈락에 대해 올바르게 예측한 비율이 98.1%로 높은 정확률을 보여주고 있다. 판별분석과 로지스틱회귀분석 결과를 종합해 보면, 중소기업 정책자금 대출의사결정에 대한 정확률이 높아 대출의사결정이 타당성이 있는 것으로 나타났다. 결과적으로 대출승인기업에 대한 자금지원도 효율적으로 이루어지고 있다고 판단된다. 한편, 평가탈락업체의 정확률이 상대적으로 낮은 것을 개선하기 위해서는 기술성과사업성을 등급화 할 수 있는 지표의 객관성과 평가자의 개인적 성향에 과도하게 영향을 받지 않도록 기술성 등 비재무지표의 평가등급에 일정범위를 주도록 하는 등 조치가 필요하다. The purpose of this study is to estimate accuracy for decision-making on policy loans for SMEs. Precise decision-making on loans for SMEs is required in order to minimize the loss of funds due to insolvency. Discriminant analysis and logit regression analysis were utilized to analyze the precision of decision-making on policy loans for SMEs. According to the discriminant analysis, a close relationship with the loan approval variables was identified in the order of credit rating, non-financial score, financial score, technical score, and collateral loan type. The classification accuracy of discriminant analysis is 92.8%.The logit regression analysis showed the relative importance of the three significant variables in the order of non-financial score, funding type, and credit rating. Classification accuracy is 98.1%, which indicates high predictability. In summary, the variables selected by both models, discriminant analysis and logit regression analysis, were credit rating, non-financial score, financial scores, and technical grades. The classification accuracy of the two models was 92.8% and 98.1%.As a result, it was verified that funding for loan approval for businesses is done efficiently.

『三國史記』의 流隕 기록에 대한 재검토 - 雨鐵이 隕石이라는 관점을 중심으로 -

신기철(Shin, Ki-chul) 호서사학회 2022 역사와 담론 Vol.- No.101

이글에서는 『삼국사기』의 천변 기록 가운데 유성‧운석 기록들을 분류했던 앞선 연구 작업을 재검토한 후, 새롭게 유성‧운석에 관한 목록을 작성하고자 했다. 우선 유성과 운석을 포괄하는 流隕이란 용어가 『宋史』 「天文志」 流隕 편부터 사용되었음을 확인했고, 다음으로 이 유운이라는 항목으로 분류한 안영숙 등과 김일권의 분류 결과를 중국 문헌을 근거로 다시 분석하여 제외해야 할 기사와 포함할 기사를 새롭게 정리하였다. 이때 流星‧星墜‧星落‧星隕‧天狗가 들어간 기사들은 『사기』 「천관서」 등을 근거로 유운으로 분류하였다. 그러나 天有聲은 그 용례가 유운 이외에 지진과 기상 등에도 쓰였기 때문에 『삼국사기』에서 天有聲만을 근거로 한 백제 비류왕 22년(325) 기사와 신라 문성왕 10년(848) 기사를 유운 기록에서 제외했다. 그리고 중국 사서에서 볼 수 있는 혜성과 유성의 특징을 분석하여 헌덕왕 7년 기사를 혜성으로 판단하고 유운 목록에서 뺐다. 다음으로 고구려 보장왕 15년(656)의 ‘우철’을 기상 기록이 아닌 운석 기록으로 볼 수 있는지 살펴보았다. 먼저 시호테-알린 운석과 캄포 델 시엘로 운석 사례로 철질운석이 비처럼 내리는 것이 실제로 일어날 수 있는 일이라는 것을 확인했다. 이규경의 『五洲衍文長箋散稿』에서 우철을 별 혹은 운석과 관련지어 보았음을 확인했다. 중국 자료인 「楮記室」에서도 우철과 운석이 관련 있음을 확인했다. 이 용례가 7세기에도 같았는지 확인하기 위해 『通典』과 『太平寰宇記』를 살펴보았다. 여기에서 당 정관 21년(647)에 黠戛斯가 중국과 교류하기 시작했고, 이때 그들이 우철로 만든 질 좋은 도검을 가져왔음을 알았다. 그러나 후에 중국인들이 黠戛斯가 강한 비로 불순물이 제거된 철광석으로 도검을 만들었다고 생각하면서 이후로 우철에 관한 사건을 신기한 일 정도로 여겼다고 판단하였다. 이처럼 7세기부터 알려진 우철이란 용어는 계속 철질운석과 관련 있는 용어로 사용되었다. 이때 우철과 이것으로 만든 도검에 관한 이야기는 黠戛斯에서 중국, 돌궐 등으로 전해졌을 뿐만 아니라 고구려에도 알려졌을 것이다. 그러므로 『삼국사기』 기사처럼 철질운석이 떨어졌을 때, 고구려인들은 우철이란 용어를 사용하여 관련 사건을 기록하였을 것이다. 이러한 분석에 따라 우철을 운석으로 보고 유운 기록으로 판단하였다. I reexamined the existing works that categorized records related to the modern astronomical terms Yuseong(流星) and Unseok(隕石) in astronomical records of Samguksagi. First, I confirmed that the term Yuwun(流隕), which encompasses Yuseong and Unseok, was used from Yuwun part, which belongs to Astronomy(天文志) in Song History(宋史). Next, I re-analyzed the previous Yuwun studies based on Chinese literature and excluded two articles including Cheonyuseong(天有聲) and one article judged as a comet from the Yuwun list. And I wanted to examine whether Goguryeo"s "Ucheol(雨鐵)" article could be judged as Yuwun"s record, not a weather record. First of all, the examples of the Sikhote-Alin meteorite and the Campo del Cielo meteorite showed that falling like rain could actually happen. I confirmed that the term "Ucheo" expresses a similar phenomenon to these events in the domestic literature of the 19th century and the Chinese literature of the 14th century. I looked up "Tong Dian(通典)" and "Tai Ping Juan Yu Ji(太平寰宇記)" to see if these uses also expressed the same phenomenon in the 7th century. According to the books, Xiájiásī[黠戛斯] began to interact with China in 647, and the Chinese at this time thought that Xiájiásī[黠戛斯] made a quality sword Ucheol. Over time, however, the Chinese thought that Xiájiásī[黠戛斯] made a sword out of iron ore from which impurities were removed due to strong rain, and since then, they have dismissed the incident of Ucheol as mysterious. Like this, the word Ucheol known from the 7th century, was used as a term related to iron meteorites until the 19th century. For this reason, when iron meteorites fell, as stated in Samguksagi"s article, Goguryeo people used the term Ucheol to record related events. Based on this analysis, it was considered appropriate to judge the article about Ucheol as a record related to Yuwun.
