`Purpose: To evaluate the results of single or combined treatment methods administered to patients with stage 1 retinal angiomatous proliferation (RAP). Methods: A retrospective clinical study was performed in 9 eyes of 8 patients with stage I RAP. According to fundus angiography findings taken regularly after treatment, the results were categorized as closure of stage 1, recurrence of stage 1, or progress to stage 2. Results: The mean follow-up period was 25 (14~40) months. In two eyes treated with laser photocoagulation only, the lesions progressed to stage 2. In two eyes treated with laser photocoagulation and intravitreal triamcinolone injection, the lesions also progressed to stage 2. In four eyes treated with photodynamic therapy and intravitreal triamcinolone injection, stage 1 lesions recurred in 3 eyes, and the lesion progressed to stage 2 in one eye. In one eye treated with photodynamic therapy, intravitreal triamcinolone injection, and laser photocoagulation, the stage 1 lesion recurred. Final visual acuity was stable in the case of stage 1 recurrence but was lower than the pretreatment level when the lesion progressed to stage 2. Conclusions: With either single or combined therapy, temporary closure of the stage 1 RAP lesion was possible, but complete closure could not be achieved for a long period because the lesion either recurred or progressed.`

수술적 절제 후의 망막혈관종성증식의 진행

Purpose: To describe the clinical course of three eyes of three patients that underwent surgical ablation as treatment of retinal angiomatous proliferation (RAP). Methods: Surgical lysis of the retinal feeding arteriole and draining venule was done in two eyes that had stage 2 RAP with serous pigment epithelial detachment (PED). It was done as the first treatment modality in one eye, and after failure of laser photocoagulation in the other. It was also performed in another eye presumed to have very early stage RAP that showed only retinal-retinal anastomosis without any definite intraretinal or subretinal angiomatous lesion. Results: PED decreased within 1 month after ablation in the two eyes with stage 2 RAP, but new anastomoses eventually developed after 1 month, followed by progression of the lesions. In the eye with presumed early stage RAP, successful lysis of retinal-retinal anastomosis was maintained and initially showed no signs of further proliferation at the original lesion site; however, four months later, hemorrhagic PED developed distally and progressed further to retinal pigment epithelial tear and massive subretinal hemorrhage. Conclusions: Surgical ablation may be unable to halt the progressive nature of neovascular proliferations in RAP.

A review team has been set up in Yong Nahm central Bureau Dong Bang Life Insurance Company to study on yearly treands and Mortalities of life insureds according to the causes of deaths. The subjects included in this study were the Life insureds in these area offices and one Who died within 2 years after the admission during 17 months period between 1984-4-1 and 1985-8-31. In cases of the insurance for educational fund, the subjects were the applicants who pay the dues of insurances instead of the insured youngsters. 1) The most frequent cause of death was malignant newgrowth, the next was heart disease, the third was central nervous vascular system diseases, and the fourth was Hepatitis and Liver cirrhosis. 2) The previous Leading cause of deaths were infectious diseases, Parasitic disease or Respiratory diseases, Such as Pneumonia bronchitis, Tuberculosis, Since remarkable prolongation of the longevity of Korean population in recent years, this has been showed marked changes after 1980, this phenomenon would be in accordance with Bogue's theory. 3) The authors hoped to extend this study to get more clear views, because it covered only a short period and very limitted areas of subjects to make a difinite conclusion on this time.

현금흐름의 지속성 및 가치관련성

한정희,홍영은 한국산업경영학회 2018 경영연구 Vol.33 No.4

This paper examines whether components of operating cash flows affect differentially persistence on future earnings and whether market participants and credit rating agencies evaluate their implications properly. Prior research has treated the cash component as homogenous. However, Roychowdhury(2006) shows that real earnings management activities affect operating cash flows. We decompose the cash component into two parts: abnormal operating cash flows related to real earnings management and normal operating cash flows, based on the abnormal cash flows measures developed by Roychowdhury(2006). We find that normal cash flows is more persistent than the abnormal cash flows. We investigate whether investors understand the implications of the differential persistence of the two components of operating cash flows. We find that stock prices act as if investors fixate on earnings, failing to correctly distinguish between the different levels of persistence of the abnormal and normal cash flows, indicating that investors misunderstand potential real earnings management. Furthermore, we examine whether credit rating agencies fully incorporate the information in normal cash flows and abnormal cash flows about future performance into their ratings. We find that rating agencies underestimate the abnormal cash flows relative to their actual persistence. 본 연구는 현금흐름의 발생원천에 따라서 발생액 시장이상현상에 차이가 있는지 분석하였다. 대부분 선행연구에서는 현금흐름을 동질적이라 가정하고 발생액 시장이상현상의 원인으로 발생에 주된 관심을 기울여왔다. 그러나 최근 실제활동이익조정과 관련된 연구들이 활발하게 이루어짐에 따라 현금흐름 관련 관심도 증대되고 있는 실정이다. 이에 본 연구에서는 현금흐름을 정상현금흐름과 비정상현금흐름으로 구분한 후 이들 구성요소와 차기 영업이익 및 차기 주식수익률과의 관계를 추정하여 주식시장참여자들이 현금흐름 구성요소가 차기 영업이익에 미치는 영향을 적절히 평가하는지 실증분석 하였다. 분석결과, 정상영업현금흐름이 비정상영업현금흐름과 비교하여 지속성이 더 높게 나타났으나, 투자자들은 차별적인 지속성효과수준을 충분하게 반영하지 못하는 것으로 나타났다. 그러나 신용평가기관의 경우 원리금상환여부에 관심이 높아 영업이익보다는 현금흐름정보를 보다 더 중요한 정보로 활용하고 있고, 실제 신용등급을 결정함에 있어 질적 재무정보를 활용함으로서 비정상영업현금흐름과 정상영업현금흐름이 차기 영업이익에 미치는 영향을 적절히 평가할 수 있다. 실증분석 결과, 정상영업현금흐름이 차기영업이익에 미치는 영향을 적절히 평가하고 있는 것으로 나타난 반면, 비정상영업현금흐름의 경우엔 과소평가하고 있는 것으로 나타나 주식시장참여자들과는 달리 신용평가기관에서는 정상영업현금흐름과 비정상영업현금흐름이 차기영업이익에 미치는 영향을 차별적으로 적용하고 있음을 알 수 있다.

가정에서의 호칭어･지칭어 사용 실태와 문제점

This paper investigates the use of address terms and reference terms within a family. This study was conducted based on the questionnaire result targeting 4,000 people in 17 administrative areas across the country. Our research focused on investigating whether the use of terms that has been recommended in <The Standard Manners of Language Use>(2011) corresponded to the actual use in Korean contemporary language life and determining how to resolve potential problems caused by inappropriate use of the terms. The result of current study revealed that there were a number of differences between the suggested terms in <The Standard Manners of Language Use>(2011) and the actual use of the terms in contemporary Korean. The difficulty in the use of address terms and reference terms within a family was largely due to its complicate system of kinship terms and the social change from patriarchal society. This study also reveals that sexually discriminated titles for husband s and wife s family need to be reformed to avoid potential problems.

‘-었더니’의 통사와 의미

이필영(Phil-young, Lee) 어문연구학회 2011 어문연구 Vol.69 No.-

The purpose of this thesis is to explain the syntactic and semantic characteristics of ‘-eossdeoni’. ‘-eossdeoni’ is constituted of ‘-eossdeo’ and ‘-(eu)ni’, but it is just a simple ending in synchronic perspectives. To identify its characteristics, we divided its relational function into three(‘sequential, discovering, contrasting’ relation) and explained each characteristics of them. In case of the sequential relation, the events of the former clause and the latter clause are occurred sequentially, meanwhile in case of the discovering relation, the event of the former clause and the perceiving process of the event of the latter clause are occurred sequentially. And in case of the contrasting relation, the former clause, the constitution of which is the perceiving process, is followed by the perceiving process of the event of the latter clause. Finally all of them share the characteristics of the sequential relations in spite of the slight differences. The another common characteristic among them is that all of them have the view of the speaker’s observing the latter clause.
