        김용재,신해룡,장강연 한국작물학회 1992 Korean journal of crop science Vol.37 No.6

        이앙기를 달리 하였을때 어린모와 25일묘, 손이앙묘의 출수반응, 수량 및 쌀의 품위차를 알아보고자 금오벼와 팔공벼, 동진벼를 공시하여 4월 20일부터 7월 20일까지 15일 간격으로 7회 이앙하여 시험한 결과를 요약하면 다음과 같다. 1. 광주지방에서 안전출수한계기(8월 27일)로 본 안전이앙한계기는 조생종인 금오벼는 어린모 : 6월 26일, 25일묘 : 7월 1일, 손이앙묘 : 7월 11일이었으며, 중생종인 팔공벼는 어린모 : 6월 21일, 25일묘 : 6월 30일, 손이앙묘 : 7월 10일이었고, 중만생종인 동진벼는 어린모 : 6월 10일, 25일묘 6월 24일, 손이앙묘 : 7월 5일이었다. 2. 육묘방법별 수량은 이앙기에 따라 일정한 경향을 보이지 않았으나 금오벼는 어린모>25일묘>손이앙묘의 순이었으며 팔공벼는 25일묘(equation omitted)어린모(equation omitted)손이앙묘의 순이었고, 동진벼는 손이앙묘(equation omitted)25일묘(equation omitted)어린모의 순으로 증수되었다. 3. 수량생산기(출수전 10일부터 출수후 30일까지)에 있어서 적산온도를 보면 금오벼는 어린모에서 최대수량을 올린 6월 5일~6월 20일 이앙에서 1,003$^{\circ}C$였고, 25일묘에서는 6월 5일~6월 20일 이앙에서 1,014$^{\circ}C$, 손이앙기는 5월 20일~6월 5일 이앙에서 1,027$^{\circ}C$이었으며, 팔공벼에서는 어린모 : 1,018$^{\circ}C$, 25일묘 : 1,015$^{\circ}C$, 손이앙묘 : 1,086$^{\circ}C$ 이었고, 동진벼에서는 어린모 : 998$^{\circ}C$, 25일묘 : 984$^{\circ}C$, 손이앙묘 : 949$^{\circ}C$에서 최대수량을 보였다. 4. 육묘방법에 따른 이앙시기별 쌀의 품위는 금오벼는 어린모에서 조기이앙에 따라 동할미가 많았고 청미가 적었으며 7월 5일 이후의 이앙에서는 청미가 현저하게 많아지면서 동할미도 증가하였다. 팔공벼와 동진벼는 이앙시기간에 차리가 인정되지 않았고 다만 극만식인 7월 5일 이후의 이앙에서만 청미 비율이 높았다. To study the effects of different nursing methods and transplanting on the growth of rice plant (Oriza sativa L.) in southern region of Korea, Kumo-byeo, Palgong-byeo and Dongjinbyeo were transplanted from April 20 to July 20 at an interval of 15 days with 8 days old seedling (infant seedling) and 25 days old box-seedling for machine transplanting, and 45 days old conventional seedling. Threshold transplanting date in southern region of Korea were June 26 for 8 days old seedling, July 1 for 25 days old seedling and] July 11 for 45 days old seedling for Kumo-byeo, and June 21, June 30, July 10 for Palgong-byeo, June 10, June 24, July 5 for Dongjin-byeo, respectively. Yield has no uniform tendency according to the transplanting date. However, yield were greater in the order of 8 days old seedling >25 days old seedling> 45 days old seedling in Kuma-byeo and 25 days old seedling (equation omitted)8 days old seedling (equation omitted)45 days old seedling in Palgong-byeo, 45 days old seedling(equation omitted)25 days old seedling(equation omitted) 8 days old seedling in Dongjin-byeo. The optimum accumulated air temperature during yield productive stage around heading (40 days from 10 days before heading to 30 days after heading) for high yield were 1,003$^{\circ}C$ for 8 days old seedling, 1,014$^{\circ}C$ for 25 days old seedling and 1,027$^{\circ}C$ for 45 days old seedling in Kumo-byeo. And they were 1,018$^{\circ}C$, 1,015$^{\circ}C$, 1,086$^{\circ}C$ in Palgong-byeo and 998$^{\circ}C$, 984$^{\circ}C$, 949$^{\circ}C$ in Dongjin-byeo, respectively. Earlier transplanting with 8 days old seedling showed higher ratio of broken rice and green kerneled rice in Kuma-byeo, and late transplanting after July 5 showed significant high rate of green kerneled rice. Palgong-byeo and Dongjin-byeo also showed high rate of green kerneled rice at transplanting after July 5.

        요소수지합판(尿素樹脂合板)의 증량에 관한 연구

        김용재,이필우,김은변 한국목재공학회 1976 목재공학 Vol.4 No.1

        This study was carried out to know the adaptability of barley flour, potato flour and white ash as extender and filler of urea-formaldehyde resin for plywood as a substitute material of wheat flour. The extenders and filler used at this study were extended by several groups of percentages. Shear strength, moisture contents, and specific gravities were compared among tested groups. The results obtained are summarized as follows. I) Wet and dry shear strength of plywoods extended by 10% barley flour, 30% potato flour, and wheat flours were shown better results than non extended plywoods. 2) There was no significant difference between plywoods extended until 50% barley flours and non extended plywoods. 3) Shear strength of plywoods extended by 50% potato and 100% barley flours were shown worse result than non extended. 4) Dry and wet shear strength of plywoods extended by white ash were shown worst result. 5) The plywoods extended by potato flours were shown nat only better shear strength, but also considered more profitable cost for extending.

      • Radical Endoscopic Antrum Surgery for the Treatment of Pediatric Sinusitis

        김용재,이상훈 대한비과학회 1998 Journal of rhinology Vol.5 No.2

        Background:The follow-up results of traditional surgical methods have yielded less positive results with children than theyhave with adults. The maxillary sinuses are commonly affected by residual mucosal diseases, so an endoscopic nasal examinationfrequently reveals recurrent polyposis. Irreversibly diseased maxillary sinus mucosa exhibiting polyposis and thickening can easilybe accessed and extirpated endoscopically. The endoscopic approach of examining the maxillary sinuses is also the easier routewhen treating younger children. Subjects and Methods:Under study were eight cases of rhinosinusitis in children aged betweenthree and fifteen years old. The patients had been unresponsive to medical treatment with antibiotics for more than three consecutivemonths but were successfully treated with radical endoscopic antrum surgery (REAS) performed with the endoscopicethmoidectomy procedure. Results:Compared to outcomes associated with conventional functional endoscopic sinus surgery(FESS), the results remained excellent during follow-ups of more than six months. Postoperative endoscopic examinations andCT scans showed air-filled antrum spaces, and resultant delays in the development of the maxillary sinus were slight (13%) whencompared with the contralateral side after FESS. Conclusion:The immediate outcome of REAS suggests success, but untowardeffects on growth of the facial bone should be evaluated with follow-up observations over the long term.

      • Orbital Complications of Rhinosinusitis: Characteristics in Pediatric Patients

        김용재,민양기 대한비과학회 2000 Journal of rhinology Vol.7 No.2

        To evaluate the differences in clinical features of rhinosinogenic orbital complications between the pediatric and adult groups,a multicenter survey was made on 79 cases of rhinogenic orbital complications (from January 1985 through October 1999). The patients ranged in age between 8 months and 79 years with a mean of 28 years. Thirty-five patients were under 15 years ofage (pediatric group), and 44 patients were over 15 years of age (adult group). Twenty-three of 35 pediatric patients (65.7%)had postseptal orbital inflammation, whereas 30 of 44 adult patients (68.2%) had postseptal orbital inflammation. The pediatricgroup had shorter symptom duration than the adult group. Pediatric OCRS also developed as various forms-inflammatoryedema, orbital cellulitis, orbital abscess and subperiosteal abscess. Sixteen of 35 pediatric patients (45.7%) underwent surgicalinterventions. The cure rate by surgical interventions in the pediatric group (14/16, 87.4%) was higher than that in the adultgroup (21/26, 80.8%). The cure rate by medical treatment in the pediatric group (18/19, 94.7%) was also higher than that inthe adult group (11/16, 68.7%).

      • Clinical Characteristics of Chronic Paranasal Sinusitis in the Patients with End Stage Renal Disease

        김용재,서민철,김민관,강보현,이봉재 대한비과학회 2001 Journal of rhinology Vol.8 No.1

        Background and Objectives:Infections account for much of the morbidity and nearly half of the mortality in renaltransplant recipient. Recently there has been a marked increase in the number of renal transplantation and preoperativescreening test for chronic paranasal sinusitis. Authors analyzed the clinical manifestations and postoperative courses after theendoscopic sinus surgery in the patients with end stage renal disease. Materials and Methods:1,175 patients had beenconsulted to the otolaryngology department for routine evaluations about the presence of acute and chronic paranasal sinusitisprior to kidney transplantation between Jun. 1989 to Aug. 1998. Among them, 30 patients were diagnosed as significantchronic paranasal sinusitis and 5 patients were treated with endoscopic sinus surgery. Medical records and radiographs of the30 patients were reviewed retrospectively. Results:The prevalence of chronic paranasal sinusitis in patients with end stagerenal disease was 2.5%. Twelve patients were asymptomatic and chief complaints of symptomatic patients were nasalobstruction (55.6%), rhinorrhea (27.8%), and postnasal drip (16.7%). Eleven patients had nasal polyps and twelve patientsshowed purulent discharge. All the patients who were surgically treated experienced postopertive bleeding and 2 of themrequired transfusion. Conclusion:The presence of asymptomatic sinusitis among the patients with end stage renal diseasenecessitates diagnositc screening tests for chronic paranasal sinusitis. The incidence of postoperative bleeding afterendoscopic sinus surgery in patients with end stage renal disease is much higher than that of otherwise healthy sinusitispatients.

      • 金融監督의 理想과 課題: 金融監督機構의 獨立性과 責任性確保

        김용재 한국금융법학회 2004 金融法硏究 Vol.1 No.2

        Bank regulators and supervisors should have a substantial degree of independence both from the government and the industry in order to fulfill their mandate and contribute to the achievement and preservation of financial stability. In addition, considering the significant role of banking supervision, proper channels of accountability should be established to complement agency independence and make it work. Recently two factors have served to emphasize on the importance of regulatory and supervisory independence (RSI). First, in almost all of the systemic financial crises of the 1990s, either weak and ineffective regulations or regulatory forbearances, largely due to the political interferences in the supervisory process, have been referred as major factors contributing to the weakening of the banks, postponing recognition of the significance of the crisis, and delaying official and effective intervention. Secondly, the discussion of the most appropriate regulatory and supervisory structure, including the organizational structure of banking supervision inside or outside the central bank, has highlighted the importance of RSI. The growing tendency of unified financial sector supervision often involves removing the banking supervision function from the central bank, where it had previously enjoyed a relatively high degree of independence regarding its monetary policy functions. This was also the case in Korea after the IMF bailout 金容載/ 金融監督의 理想과 課題: 金融監督機構의 獨立性과 責任性確保115 The Korean Journal of Financial Law, Vol. 1, No. 2 (2004) The Goal and Task of Banking Regulation and Supervision Yongjae Kim of 1997. Korea prior to the 1997 crisis is a representative example of the effects that a lack of independence can have on banking supervision. Commercial banks were under the direct authority of the monetary board (the governing body of the Bank of Korea) and the Office of Banking Supervision. Specialized banks and nonbank financial institutions were under the direct authority of the Ministry of Finance and Economy (MOFE). The MOFE’s supervision of nonbanks was generally recognized as so weak and created conditions for regulatory arbitrage and excessive risk-taking, especially among merchant banks, which was a contributing factor to the 1997 crisis. Furthermore, the supervisors had the authority to waive regulatory requirements, which led to widespread forbearance and which made enforcement nontransparent. In recognition of the weakness of supervision, Korea has reformed its supervisory system to provide it with more autonomy and to eliminate the regulatory and supervisory gaps. However, the reform has proven to be a failure because it does not give any RSI to a new financial supervisor, especially to the Financial Supervisory Service (FSS). This paper aims at searching for any alternatives to the current financial supervisory system which ensures RSI for the FSS. RSI is the goal and task of banking regulation and supervision, thus continuously attaining financial stability in Korea.
