오이식,정두윤 釜慶大學校 1998 釜慶大學校 論文集 Vol.3 No.2

Using several complexing agents, plating rate and plating condition of electroless Ni-Cu-B plating have been studied. The result obtained from this experiment summarized as follow: It was found that the optimum bath composition consisted of 0.1M nickel sulfate, 0.02M copper sulfate, 0.07M DMAB as reducing agent and 0.15M malic acid as complexing agent, whereas the bath of pH 8 adjusted by ammonia solution and 70℃of bath temperature gave good result. The activation energy between 40℃ and 70℃ was calculated to be 34.8 kj/mole for deposition. Plating reaction had been ceased by increase of temperature above 90℃, pH higher than 8 and under 4. Deposited surface became worse in case of the increase of bath temperature above 80℃.

The purpose of this study was examined status and wrongs of international sports administration of south korea and proposed improvemental directions. Domains of international sports administration were sports cooperation among nations and international corporation, helding and participation in international events, sports interaction between south korea and north korea. 1. In sports cooperation among nations and international corporation history of sports interaction was short and the number of treatment of sports interaction between south korea and other nations were 19. The number of treatment of sports interaction between KOC and other nation olympic committees were 33. Since L.A. olympic records of olympic games of south korea have been over tenth and as for asian game since first game records of south korea have been upper level but status of south korea in international corporation was lower. The number of athletics and men of interaction were a few. 2. In helding and participation in international sports events participating in sports events was appropriate but in helding international sports events need considering validity of politic, economic, etc. 3. In sports interaction between south korea and north korea roles of sports was loosing of tension and helping uniting of south korea and north korea and reinforcing ties of korean dwelling in out of korea.

상부요로계감염 환자에서 Gallium-67 Citrate 스캔 및 Tc-99m Dimercaptosuccinic Acid(DMSA)스캔의 임상적 의의

It is often not certain whether the focal defect of renal cortex of Tc-99m Dimercaptosuccinic acid(DMSA) renal scan in patients with acute pyelonephritis means the cortical scar by previous inflammation or recent active inflammatory lesion. Gallium-67 citrate(Ga-67) also has been known to be accumulated at the active inflammatory lesion. In order to evaluate the usefulness of the Ga67 and Tc-99m DMSA renal scan in patients with acute pyelonephritis, we reviewed the results of both study and clinical findings. Nintecn patients with typical clinical findings of acute pyelonephritis and admitted to our institute from Jan. 1998 to Nov. 1998 were included in this study. Tc-99m DMSA and Ga-67 scan were performed mean 3.3 and 7.3 days after admission. Eleven of 19 patients (57.9%) showed abnormally increased focal renal uptake on the Gallium-67 citrate scan and 14 of 19 patients(73.7%) had a cortical defect on the kidneys in Tc-99m DMSA scan. Seven(36.8%) patients had an abnormality in both study. Seven(36.8%) patients had an abnormality only in Tc-99m DMSA scan and 4 (21.1%) patients had an abnormality only in Ga-67 scan. Of 7 patients who had an abnormality on both scan, 5 patients had. an abnormality at same region in both scan and 2 patients had an abnormality at the different sites on the kidneys. With the above results, we speculate that Ga-67 scan and Tc-99m DMSA scan play a complementary role in the patients with upper urinary tract infection.

땅콩의 결협율 향상과 화기내 Cytokinin함량과의 관계를 검토분석한 결과는 다음과 같다. 1. 화기의 착생위치별로는 1차분지에서는 저위분지, 자엽절 분지에서는 기부절(제1-2절)에서 Cytokinin함량이 높았다. 화기의 채취시기별 화기내 Cytokinin함량은 분지종류 및 분지위치에 관계없이 DAF 7, DAF 10, 개화당일의 順이었다. 2. 低位節(제1-2절) 절제시 頂部節(제5-6절) 화기내 Cytokinin함량은 DAF 7과 DAF 14구가 무절제구보다 각각 112, 337% 높았다. 3. 主莖 出液중 Cytokinin함량은 화기내 Cytokinin보다 월등히 높았다. 4. 자엽절분지에서 결협율은 화기내 Cytokinin 함량과 밀접한 관계를 보였다. Contents of cytokinin of cotyledon branch and first branch among primary branches were higher than those of other branches. Contents of cytokinin of basal part (first and second nod) of primary branches were higher than those of upper nod (fifth and sixth nod). Contents of cytokinin of floral instrument with days after flowering were high at DAF 7, DAF 14, DAF 0 orderly irrespective of kinds of branch and position of nod. Contents of cytokinin of upper nodal part with removing the lower nodal part (first-fourth nod) were high by 112-337% at DAF 7 and DAF 14 compared with those of the control plot. Contents of cytokinin of an extract from cutting site of main stem were much more than those of floral instruments. Pod-setting ratio of flowers versus flower position on the cotyledon branch was closely related with the cytokinin contents of floral instruments.

In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

Bolt failure is a hazard factor for the safety of reactor vessels in nuclear power plants. However, in the practical application of ultrasonic technique for crack detection in stud bolt, the classification of crack signal from the signals reflected from threads in stud bolt is very difficult. In this study, shadow effect technique combined with new signal processing method has been investigated to enhance the detectability of small crack initiated from root of thread in stud bolt. The key idea of new signal processing concept is based on the fact that the shape of waveforms from the threads is uniform since the shape of the threads in a bolt is same. If some cracks exist in the thread, the flaw signals are different from the reference signals. It has shown that the small flaws can be effectively detected by novel ultrasonic technique combined with this new signal processing concept.

본 연구는 군집 분석을 이용하여 알코올 의존 환자의 MMPI 임상척도와 내용 척도의 특성을 알아보았다. 연구 결과, 60명의 남자 알코올 의존 환자들은 2개의 하위 유형으로 분류되었다. 첫 번째 집단은 모든 척도가 T 점수 45 ~ 55 범위에 있는 정상 유형이었고(n=40, 66.6%), 두번째 집단은 MMPI 타당도 척도의 L, F, K 가 역전된 V형이며 임상 척도는 6-8 유형을 보였다(n=20, 33.4%). 내용 척도에서도 두 집단간에 통계적으로 유의미한 차이가 있었는데, 첫 번째 집단은 프로파일이 정상범위에 속했으며, 두 번째 집단은 ANX, FRS, OBS, HEA, BIZ, ANG, HYP, LSE, SOD, TRT 척도의 T 점수가 첫 번째 하위 유형에 비해 의미있게 상승하였다. 본 연구는 MMPI 임상 척도와 내용 척도가 알코올 의존 환자의 임상적인 진단과 연구에 도움이 된다는 것을 시사한다. This study was to investigate the characteristics of MMPI clinical and content scales on patients with alcohol dependence by using cluster analysis. As a result, the 60 male patients with alcohol dependence were classified into two subtypes. The MMPI profile of first subtype was within normal range, 45~55 of T score(n=40, 66.6%), second subtype had the inverted V shape validity scales and 6-8 clinical scale profile(n=20, 33.4%). The content scale was statistically significant difference between two groups. First subtype was within normal range, second subtype had more elevated T score of ANX, FRS, OBS, HEA, BIZ, ANG, HYP, LSE, SOD, and TRT scale. This study suggest that the MMPI clinical and content scale can be helpful and applicable to clinical diagnosis and research in patients with alcohol dependence.

In rehabilitation programs involving muscle re-education and endurance exercise, it is necessary to confirm when fatigue occurs. It is also necessary to quantify fatigue, to confirm whether the muscle has been exercised sufficiently. In general, as fatigue occurs, the force-generating ability of the muscle is reduced. If the median frequency (MDF) obtained from electromyograrn (EMG) power spectrum is correlated highly with work, then the timing and degree of fatigue may be confirmed. This study examined the relationship between work and MDF obtained from the EMG power spectrum during repetitive isokinetic exercise. Surface EMG signals were collected from biceps brachii and vastus lateralis of 52 normal subjects (26 males, 26 females) at 120˚/sec and 60˚/sec while performing an isokinetic exercise. The exercise was finished at 25% of peak work. MDF data was obtained using a moving fast Fourier transformation (FPT), and random noise was removed using the inverse FPT, then a new MDF data was obtained from the main signal. There was a high correlation between work and MDF during repetitive isokinetic exercise in the biceps brachii and vastus lateralis of males and the biceps Brachii of temales (r=.50∼.77). However, there was a low correlation between work and MDF in the vastus lateralis of females (r=.06∼.19).

땅콩의 無效開花를 抑制하여 精粒率이 높은 栽培法을 講究하기 위하여 C-MH을 開花後 24日, 28日, 31日에 500倍液, 1,000倍液, 1,500倍液으로 달리하여 處理한 試驗 結果는 다음과 같다. 1)主莖長은 無處理에 比하여 38∼44% 減少되었으나 分枝數는 處理時期, 濃度에 關係없이 變化가 거의 없었다. 2)處理後 28日의 開花抑制率은 500∼1,000倍液 處理時 29∼38%, 1,500倍液 處理時 22% 였다. 3)C-MH處理에 따른 完熟粒率(=精粒率)은 無處理區(56%)에 比하여 開花後 28日 處理時 55∼59%이고, 이중 1,000倍液 處理區에서 59%로서 3%가 向上되었다. 4)開花後 28日에 1,000∼1,500倍液 處理區와 開花後 31日에 1,000倍液 處理區의 收量이 無處理區와 對等하였다. C-MH(Cholinesalt of maleic hydrazide, 39%) has been applied on peanut(Arachis hypogaea L.) plant in 1994∼1995 at the time of 3 different times, 38 accumulative flowers(=24 days after flowering;DAF), 50 flowers(=23 DAF), 63 flowers(=31 DAF) and at the 3 different level of 500, 1,000, 1,500 double the solution. Main stem length was noticeably retarded by 38∼44% compared to that of control. Branch numbers were not changed at any treatment conditions. Ratio of flowering inhibition to control plot was 38% at the 500 double the solution and 22% at the 1,500 double the solution at the time of 50 accumulative flowers, respectively. Ratio of uniform matured seed was slightly enhanced by 3%. Namely, that of control plot was 55.6% and that of 1,000 double the solution at 50 accumulative flowers was 58.6%. Yield productivity of 1,000 double the solution at 50 accumulative flowers was increased by 7% compared to that of control(3.2MT/ha).
