Using a partial D‐loop sequence of mtDNA, an intensive analysis was conducted of the maternal lineages of Jeju native pigs (JNPs) from Korea. In total, 100 mtDNA sequences were obtained from Asian wild boars (AWBs), European wild boars (EWBs), Asian domestic pigs (ADPs), European domestic pigs (EDPs), and JNPs and were used for phylogeny and network analyses. Two distinct JNP groups - one (JNPA) in the Asian cluster and the other (JNPE) in the European cluster - were identified in the estimated phylogenetic tree and network. The maternal lineage of JNPE was the closest to that of EWB and a clear haplogroup was identified that shared an identical haplotype (hap04) among 15 individuals of JNPE and 2 individuals of EWB. A Landrace and an EWB shared hap03with a JNPE. EWB, Landrace, Large White, and Duroc formed two clear haplogroups with JNPE in a parsimonious medianjoining network analysis, suggesting that an obvious maternal contribution of EDP has occurred in JNPE in recent years. A pair‐wise mismatch analysis also indicated that JNPE may have experienced a sudden population expansion, suggesting a more recent establishment compared with the gradual population expansion of JNPA. The JNPE group therefore should be further evaluated in order to decide whether this group should be culled or accepted into further programs for maintenance of the JNP population as a pure breed.

본 硏究는 養液栽培時 養液濃度와 培地種類가 대립계 포도품종인 Black Olympia의 生育과 果實品質에 미치는 영향을 구명하고자 하였다. 新梢長은 0.5배에서 1.5배의 양액농도에서 농도가 높을수록 길었고, 배지종류별로는 0.5배 농도에서는 밭흙과 퇴비를 1:1로 혼합한 배지에서 신초장이 길었으나 1.5배 농도에서는 오히려 짧게 나타났다. 節間長은 저농도의 양액농도에서는 밭흙과 퇴비를 혼합한 배지가 길었으나 1.5배의 고농도에서는 차이를 보이지 않았다. 각 배지에서 濃度가 높을수록 간경이 크게 나타났으며 배지종류간에는 펄라이트와 버미큘라이트 혼합배지가 밭흙과 퇴비를 혼합한 배지보다 컸으나 유의차가 없었다. 果房重은 각 배지에서 1.0배의 양액농도가 가장 무거웠으며 배지 종류간에는 밭흙과 퇴비를 혼합한 배지가 더 무거웠다. 糖度는 각 배지의 1.0배 양액농도가 높았으며 배지종류간에는 차이를 보이지 않았다. 果皮의 안토시아닌 함량은 배지별로 밭흙과 퇴비를 혼합한 배지에서 높았으며 양액농도별로는 1.0배에서 높게 나타났다. 收量은 펄라이트와 버미큘라이트를 혼합한 배지에서 양액농도가 높을수록 많았으나 밭흙과 퇴비 혼합배지에서는 1.0배의 농도에서 높게 나타났다. This study was carried out to investigate the effects of ionic strength and substrates on growth and fruit quality, and to establish fruit tree nutrient solution culture. The higher ionic strength showed the longer shoot length of grape. Among the substrates, upland soil+compost showed longer shoot length than perlite+vermiculite in 0.5 strength but shorter in 1.5 strength of Hoagland solution. Internode length was longer in upland soil+compost than in perlite+vermiculite in 0.5 strength, but there were no significance in 1.0 and 1.5 strength of Hoagland solution. Higher ionic strength and/or perlite+vermiculite of substrates showed tricker in trunk diameter than lower ionic strength and/or upland soil+compost. Cluster weight was heavier in 1.0 ionic strength than the others. Cluster weight in upland soil+compost was heavier than that of perlite+vermiculite. Soluble solids content of berry was the highest as much as 17.3。 Bx on 1.0 ionic strength of three strength, but there are no significances in substrates. Anthocyanin content of grape skin was higher in upland soil+compost than perlite+vermiculite, as well as the highest in 1.0 strength among three strengths. The higher ionic strength showed the more berry set. Each substrate showed uniformal berry set and growth. The best result in berry yields was obtained in 1.0 ionic strength with substrate of upland soil+compost in comparison to other treatments.

Objectives: The aim of this study was to describe the clinical characteristics of enuretic children and to evaluate the efficacy of treatments. Methods: Our study subjects enrolled were 52 children with nocturnal enuresis, who visited outpatient clinic of pediatrics in Seoul Paik Hospital and Ilsan Paik Hospital, during the period from October 1998 to August 2004. The data of gender, age, family history, symptom, clinical type of enuresis and drug therapy were collected and analyzed retrospectively. Results: The male : female ratio was 2.25 : 1. The mean age at diagnosis was 6.8 years with an age range from 4.3 years to 12.5 years. Fourty five cases(86.5%) were diagnosed as primary enuresis and 7 cases(13.5%) were diagnosed as secondary enuresis. A family history of enuresis was noted in 5 cases(9.6%) including 4 cases with parental enuresis history. The accompanying urinary symptoms were urgency(11.5%), frequency (7.7%), and dysuria(2.0%). Conclusion: We found frequent occurrences of enuresis in boys and primary type and an occasional association with a family history of enuresis. The two main treatment modalities were behavior control with an alarm system and drug therapy with imipramine, desmopressin, or oxybutynin. We recommend continuous drug medications to control nocturnal enuresis along with encouragement.

The effect of low-intensity ultrasonography on dislocation of the patella and fracture healing is controversial, and current management of that does not generally involve the use of ultrasound therapy. Nine patients with dislocation of the patella were treated with low-intensity ultrasonography(l5 mW/㎠, 1∼3.3 MHz) per 10-15 min/days, with an interval of 3 days during the last 3 weeks, at Family Animal Hospital(in Kunsan city). Ultrasound therapy may be beneficial to dislocation of the patella and healing. This finding is of considerable importance in that treatment with a low-intensity pulsed ultrasound signal may reduce healing time and could yield substantial cost savings and decreases in disability associated with delayed healing of dislocation of the patella.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

복숭아나무 경지삽목 번식에 있어서 삽수 굵기와 길이 및 삽수내 저장 양분 함량이 발근과 포장활착에 미치는 영향을 구명하였다. 삽수 굵기는 直徑 5∼8㎜의 삽수가 발근율이나 발근수, 발근장 등 뿌리 발달이 좋았으나 포장 활착율은 삽수재 저장양분이 많은 직경 8∼11㎜가 좋았다. 삽수 길이는 20∼30㎝ 처리가 발근율, 발근수, 발근장 등 발근력이 좋았으나 포장 활착율은 삽수재 잔존 저장 양분이 많은 30㎝ 길이가 좋았다. 삽목용 적정삽수는 8㎜ 굵기에 30㎝ 길이가 가장 효과적이었으며 포장에서 활착후 묘고, 간경 등 생육은 모든 처리에서 116㎝ 이상, 20.4㎜ 이상으로 삽목 당년에 우량묘가 생산되었다. This experiment was studied to examine the effect of cutting size and storage nutrient on rooting and survival in field using hardwood cutting of 'Sunaga Wase' peach to establish mass production system of rooted cutting. Cuttings having 5 to 8㎜ in stem diameter showed the best rooting percentage, root number and root length. In the survival in field, the stem diameter of 8 to 11㎜ showed the highest survival rate and less consumption of storage nutrient during cutting. Those hardwood cuttings of 20 to 30㎝ in stem length showed the best rooting, and higher survival in field was obtained in 30㎝ long cuttings. After transplanting rooted cuttings to field, tree height and trunk diameter of 'Sunaga Wase' peach was 116㎝ and 20.4㎜, respectively.

김현수,김현철,임병수 成均館大學校 科學技術硏究所 1994 論文集 Vol.45 No.1

The effects of temperature, stress ratio and frequency on the fatigue crack propagation have been investigated using STS 410 Stainless Steel. The temperatures employed were room temperature(27℃), 300℃ and 500℃. The stress ratios were 0.1 and 0.3 and the frequencies were 20 and 30Hz. Some of the conclusions obtained are as follows. (1) As the temperature increased, da/dN became greater, however, with the greater stress ratio, this tendency became smaller. (2) The change of frequency to a higher value at a given temperature had little effect on da/ dN. (3) The increase of stress ratio increased da/ dN, however, this effect became smaller at higher temperature.

The purpose of this study was to compare the amount of calcium fluoride deposited on the enamel and dentin surface and to obtain information on the morphological change and crystallographic details of mineral deposition after 12,000ppm APF application in vitro. The bovine enamel and dentin blocks were randomly assigned to eight groups according to artificial caries lesion formation and difference of fluoride application time. The fluoride concentration and morphological characteristics on the treated enamel and dentin surface were investigated by using fluoride quantitative analysis and SEM. The powdered enamel and dentin of the intact bovine incisors were prepared for the X-ray diffraction analysis. The following results were obtained. 1. The amounts of KOH-soluble fluoride on the carious enamel and dentin surface after 24h APF application were higher than after only 5min APF application(P<0.05), but in the case of the sound enamel and dentin surface were similar after 5min and 24h application (P>0.05). The fluoride content was highly increased in the carious dentin as compared with sound dentin after APF application(P<0.05). 2. The caruous enamel surface after APF application, the demineralized enamel surface were recovered a more dense enamel surface and precipitation of crystal was observed a distintive surface layer of spherical globules of about 1 m diameter. In the case of the fluorided carious dentin surface, precipitation of calcium fluoride-like material was deposited both inside the dentinal tubules as well as in the intertubular regions. 3. The crystallographic structure of powdered enamel and dentin after 24h APF application had large crystallities of apatite and CaF2 diffraction peaks in the enamel as compared with dentin. The diffraction data collected from the 27.50-29.50(2) angular range of the powdered enamel, the (105) apatite, (225) apatite and (111) CaF2 peaks of the enamel crystallities were detected after 24h APF application.

고온에서의 P92강 용접부의 피로균열 성장거동

김범준,임병수 成均館大學校 科學技術硏究所 2002 論文集 Vol.53 No.1

To meet the demand for higher efficiency of power plant, high strength and heat resisting steels have been developed to improve the fatigue crack resisting properties under high steam pressure and temperature condition in power plants. As the result, P92 steel which has tempered martensitic 9% Cr and which is strengthened by replacing Mo with W, can be used for piping material that is critical in fossil power plant. Since the pipes are jointed by welding, the fatigue property, strength and life of weldment at high temperature is very important. In this study, the effect of high temperature on fatigue crack growth behavior in weld metal, HAZ(Heat Affected Zone) and base metal of P92 steel were investigated. Fatigue test was conducted under sinusodial waveform with constant load ratio(R=0.1) and frequency(f=20㎐) using CT specimens. Test temperatures were 600Δ℃. 650℃ and 700℃ and fatigue crack growth rates were characterized by the ΔK parameter at each test temperature.
