Between 1981 and 1985, 19 diabetic patients with end-stage renal disease aged 34 to 75 years(mean age 52. 3) were treated with continous ambulatory peritoneal dialysis(CAPD) for periods of 6 days to 24 months(average 7. 8 months). Eight patients were treated for 12 months or more. Mean duration of diabetes before CAPD was 1 2. 7 years. Extrare nal complications were frequent at the start of CAPD: hypertension in all lg patients, retinopathy in 16, symptomatic peripheral neuro- pathy in 6, cataract and pericardial effusion in 4 each, ischemic heart disease in 3 and cerebrova- scular disease in 2. All patients had at least 2 complications and 12 patients had 4 or more complications simultaneously. The actuarial patient survival rate was 73. 5 %and the technique survival rate 68. 2% at one year. The patient and technique survival rate for non- diabetic patients during the same peiod were 90. 2 and 72. 3o respectively. The patient survival rate was significantly lower in diabetic than in non-diabetic patients(p(0. 001) The technique survival rate was not different nor was the in cidence of peritonitis and catheter exitsite infection between the 2 groups. Fasting blood sugar control was satisfactory with intraperitoneal infusion of regular insulin. Blood pressure control was also satisfactory: antihypertensive drugs were discontinued or the dose reduced in 13 of 19 patients. The hematocrit and serum albumin were higher one year after CAPD although not statistically significant. Visual acuity remained poor and unchanged in 5 patients during the mean follow-up period of 7. 5 months. In conclusion, CAPD with intraperitoneal administration of insulin may be a good alternative treatment for diabetic patients with end-stage renal disease.

Porous copper bromide (CuBr) films are highly advantageous for detecting ammonia (NH₃). The fabrication of porous CuBr films requires complex high-temperature processes or multistep processes. Herein, we report the uncomplicated preparation of porous CuBr films by a spin-coating method and the films’ excellent NH₃ sensing properties. The porous films were prepared by spin-coating 100, 150, and 200 mM CuBr solutions, and then dried in a vacuum oven for 2 h. All the films showed a high NH₃ response; in particular, the film prepared using a 100 mM CuBr solution showed an extremely high response (resistance ratio = 852) to 5 ppm NH₃. The film also showed fast response and recovery times, 272 s and 10 s respectively, even at room temperature. The outstanding NH₃ sensing characteristics were explained in relation to the porosity and thickness of the prepared films. The high-performance NH₃ sensors used in this study can be used for both indoor air quality and environmental monitoring applications.

중소기업 여부와 회계 보수주의 간의 관련성 : 상장기업을 중심으로

[Purpose]The demand for accounting conservatism may vary depending on whether a firm is SME or not. Previous studies have focused on the accounting conservatism to be affected by the firm’s characteristics including a status of listing. However, the relationship between the firm’s SME status (SME vs. non-SME) and accounting conservatism has not yet been addressed yet. This study analyzes whether there is a difference in accounting conservatism between SMEs and non-SMEs in Korean stock exchanges(i.e. KOSPI, KOSDAQ). [Methodology]SMEs in the test sample were identified under the Basic Law on Small and Medium Businesses and the Enforcement Decree, and accounting conservatism was measured by the methods of Basu (1997) and Ball and Shivakumar (2005). The test period is from 2011 to 2020, and the test sample is companies listed on the KOSPI and KOSDAQ markets. [Findings]As a result of the analysis, even after using control variables, accounting conservatism was greater in SMEs compared to non-SMEs in Korean stock market. These results were more pronounced when the auditors were large and the market was KOSPI. The similar test results were obtained even after controlling for firm’s discretionary accrual and financial reporting opacity. [Implications]In the context from prior literature arguing that the demand for accounting conservatism is greater when information asymmetry and agency costs are large, this study’s results provide additional empirical evidence that even a listed company may show differences in accounting conservatism depending on the SME status. [연구목적]본 연구는 중소기업 여부에 따라 회계 보수성의 수요는 차이가 있을 것임에도 불구하고 선행 연구에서 회계 보수성이 기업의 상장 여부(public vs. private)와 상장시장 간 비교(KOSPI vs. KOSDAQ)로 진행되었으나, 아직 중소기업 여부(SME vs. non-SME)와 회계 보수주의의 관계에 대해서는 분석한 바가 없다는 점에 주목하였다. 이에 본 연구는 상장 중소기업과 대기업의 회계 보수성에 차이가 있는지 분석하였다. [연구방법]중소기업 여부는 중소기업기본법에 및 시행령에 따라 식별되었고, 회계 보수주의는 Basu(1997)과 Ball and Shivakumar(2005)의 방법론을 이용하였다. 분석기간은 2011년부터 2020년까지이며 분석대상은 유가증권시장과 코스닥시장에 상장된 기업이다. [연구결과]분석 결과, 일정한 변수를 통제한 후에도 상장 대기업과 비교할 때 상장 중소기업에서의 회계 보수성이 더 크게 나타났다. 이러한 결과는 감사인의 규모가 큰 경우, 소속시장이 유가증권시장인 경우 뚜렷하게 나타났으며, 개별 기업의 재량적 발생액과 재무 보고의 불투명성을 통제한 후에도 중소기업일수록 회계 보수성이 크다는 주된 분석과 같은 결과를 도출할 수 있었다. [연구의 시사점]이상의 연구 결과는 회계 보수성의 수요가 정보의 비대칭성이 크고 대리인 비용이 큰 경우에 더 크다는 선행연구를 바탕으로 볼 때, 같은 상장기업이라도 중소기업 여부에 따라 회계 보수성이 차이가 있을 수 있음을 시사하였다는 점에서 의의가 있다.

이케아 디자인 개발 성공 요인에 관한 연구

김상권 한국가구학회 2019 한국가구학회지 Vol.30 No.3

Since IKEA, the world’s largest furniture maker, opened its first store in Gwangmyeong, Gyeonggi Province, in 2014, IKEA Korea saw its sales jump 29 percent on-year to 471.6 billion won in the 2018 fiscal year. At the same time, the number of IKEA family members has reached 1.6 million and the total number of visitors per year has exceeded 8.7 million. IKEA Korea representative said that annual growth rate of 29% is meaningful in IKEA. “It shows that Korea is the fastest growing market among the countries that IKEA has entered.” These success factors make it possible for consumers to recognize IKEA as a home-punishing store for each line of products displayed in the store, as ‘IKEA offers everything in the home.’ At present, IKEA has about 9,500 products and is developing products that are in perfect harmony with form, function, quality, environment friendliness and low price. These efforts are the driving force behind IKEA’s differentiation strategy and IKEA as an innovative company, leading the home furnishing industry by developing products that reflect consumer lifestyles. Therefore, in-depth analysis of the design philosophy, design style, and design development strategy for IKEA’s product development is required, and corresponding countermeasures in the domestic industry are urgently required.

Cystic lesion of the jaw are frequently encountered clinically. Although they rarely lead to development of tumors, they can result in resorption of the jaw bone or asymmetry of the face may occur. The purpose of this study is to find the clinical and histopathological pattern of cysts and to help better understanding for the diagnosis and treatment of jaw cysts. The hospital chart, out-patient chart, panorama X-ray, histopathological report and operation report of 246 patients were reviewed who had been diagnosed as cyst. Sex distribution, age distribution, classification, anatomic distribution, clinical sign & symptoms, treatment, post-operation complications, recurrence rate were studied. Then significant difference between the diameter of cyst with bone graft and none-bone graft was calculated with SAS program. The results were as follows. 1. Among the total patient of 246 cases, male were 163 case(67.0%), and female were 83 case(37.0%), male predominated by the ratio of 1.98. 2. By age group, the 20's accounted for the largest proportion of the cases(27.2%) and the 30' accounted for the 2nd largest proportion of the case(19.5%). 3. Radicular cyst and dentigerous cyst were most common cysts, irrespective of 166 case(67.5%) and 62 case(25.2%). 4. Clinical sign & symptoms were swelling(167case), pain(85case), pus discharge(53case), teeth discoloration(28case), indicating that most complaints were related to inflammation and facial asymmetry. 4.9% of the total cases were discovered accidentally. 5. The primary site of cysts were maxillary anterior area(43.9%), the others were, in descending order, mandibular posterior area(25.6%), maxillary posterior area(14.6%). 6. Enucleation with endodontic treatment was a main treatment method(133 case, 54.1%) and 38 cases(15.4%) were enucleation with extraction, and 37 cases(15.0%) were only enucleation, and 21 cases(8.5%) were enucleation with bone graft. 7. The average diameter of cysts with bone graft was significally greater than with non-bone graft(p<0.05). 8. Post-operation complications occurred in 10 case(4.1%), all of this were due to secondary infection.
