Purpose : This study was carried out to identify the factor of decisional balance for exercise. This was composed of a set of variables at the level of decision making when the elderly decide to do exercise. It was used to classify and identify the characteristics of the stages of change for exercise to which the elderly belong, and was used to identify the variables of decisional balance which influence the stage of change for exercise in the elderly. Methods : Convenient samples of 198 subjects over age 60 in Seoul(mean age=70) were selected from community living, mentally competent older adults and the data was collected from April 1, 1999 to May 31, 1999. The research instrument was the Decisional Balance Measure for Exercise(Marcus & Owen., 1992), Stage of Change Measure(Marcus et al, 1992). The data was analyzed by SAS Program. Results: 1. According to stage of change measure, without missing data, 191 subjects were distributed in each stage of change for exercise : 50 subjects(26.1%), 7 subjects(3.6%), 52 subjects(27.2%), 4 subjects(2%), and 78 subjects(40.8%) belonged to the pre-contemplation stage, contemplation stage, preparation stage, action stage and maintenance stage. 2. Factor analysis identified 3 factors of decisional balance as appropriate factors for excise of the elderly and named by researchers; 1)'Perceived Physical-psychological benefit', 2)'Perceived Physical-psychological burden', and 3)'Perceived time burden'. 3. The analysis of variance showed that the two components Perceived Physical - psychological benefit(F=45.95, p=.0001), and Perceived Physical-psychological burden(F=26.52, P=.001) were significantly associated with stage of change. 4. Through the discriminant analysis, it was found that both 'Self Perceived Physical-Psychological benefit' and 'Perceived Physical-Psychological burden' were the influential variables in discriminating the three stages of change(pre-contemplation, preparation, and maintenance). Conclusion: Results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behaviors. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for exercise intervention about especially the factors relating to decision making for exercise of the elderly in the different stages of change of exercise.

본 연구는 조선시대 유학자인 농암(農巖) 김창협(金昌協, 1651-1708)의 학문 수용 과정을 지각론을 중심으로 살펴본 것이다. 김창협은 율곡학파 계열의 학자이지만 퇴계 이황의 학설에 호감을 갖고 이를 긍정하여 자신의 학파와 절충하는 독특한 사상을 전개하였다. 율곡 이이의 사단칠정론에 대해 반대한 것은 아니지만 비판적 입장을 취하면서, 리발(理發)을 중심으로 하는 퇴계 이황의 이론을 수용하였다. 그것은 호락논쟁으로 이어지면서 김창협의 학문적 성숙을 유도하였고, 마침내 지각설이라는 이론 체계로 드러났다. 그의 지각론은 첫째, 성(性)은 성즉리(性卽理)의 입장에서 파악해야 하고 지(智) 또는 리(理)를 중심으로 해석해야 한다는 것, 둘째, 지(智)는 분별의 리(理)로 해석하는 것이 옳고, ‘밝게 비춘다’라는 구절의 해석에서 기미와 색상은 자연스럽게 드러난다는 점, 셋째, 지(智)는 사물의 시비득실(是非得失)의 차별을 구별하고 판단하는 기준이 된다는 점 등이 강조되었다. 다시 말하면, 인간은 사물을 접하게 마련이고, 심(心)의 지각은 이를 감각 기관을 통하여 받으며, 지각을 통해 받아들인 것은 인의예지신(仁義禮智信)의 성(性)에 의해 정해지고, 인간은 자신의 행동을 결정하며, 지는 인간의 내부에서 구체적인 정(情)의 작용인 측은지심, 수오지심, 사양지심, 시비지심의 모습으로 나타난다는 것이다. 이러한 인식은 인간을 주체이고 능동적 역할을 하는 존재로 부각시키는 사상적 근거가 된다. This research aimed to review the process regarding acceptance of studies about Nongam Kim Chang-Hyeop who was a confucian of Joseon Dynasty with the theory of intelligence and perception as the central figure. Being the scholar of Yulgok school, Kim Chang-Hyeop was interested in Toegye Lee Hwang`s theory, agreed with it, made a compromise with his school, and developed his unique thought. Although he did not object to Yulgok Lee Yi`s Sa Dan Chil Jeong Non(四端七情論, it is a theory regarding Sa Dan which are perfect virtue, righteousness, courtesy, and perception according to the theory of Mencius. and Chil Jeong which are pleasure, anger, sadness, joy, love, hate, and avariciousness), he took a critical attitude regarding it and accepted Lee Hwang`s theory with Li Bal(理發, appearing principle law) as the central figure. It was followed by Ho Rak Non Jaeng(湖洛論爭, it is an argument regarding whether human nature and thing`s nature are same or not), led the maturity of Kim Chang-Hyeop`s study, and finally appeared with the theoretical system of intelligence and perception. His theory of intelligence and perception emphasized that first, nature is perceived by "nature is principle law" and interpreted by intelligence or principle law. Second, it is right that intelligence is interpreted by principle law of discernment and smell, taste, and color naturally appear with interpretation of "shine brightly on." Third, intelligence is the criterion of discernment and judgement regarding differentiation of Si Bi Deuk Sil(是非得失, right, wrong, obtaining, and losing) about things. In other words, a person always faces any things, intelligence and perception of mind is arranged through sense organ, things accepted through intelligence and perception are determined by the nature of In Ui Ye Ji Sin(仁義禮智信, perfect virtue, righteousness, courtesy, intelligence, and trust), people determine their action, intelligence appears with the working of feeling which are Cheuk Eun Ji Sim, So O Ji Sim, Sa Yang Ji Sim, and Si Bi Si Sim. This perception becomes a foundation of thought which emphasizes human beings as a active role and a subject.

This study is carried out to examine the effect of applying Feldenkrais method, elastic band training and combined training on trunk muscle. The subjects of this study were 32 modern dance majors and they were divided into four groups which consists of 8 peoples each, Feldenkrais method group(modern dance + Feldenkrais method), elastic band training group(modern dance + elastic band training), combined training group(modern dance + Feldenkrais method + elastic band training), and control group(modern dance). Measurement variables which are trunk muscle were measured before training, and after 4 and 8 weeks training and the results are as follow: In the left muscle strength change at Centaur 0°, Feldenkrais method group, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and combined training group had significant increase after 8 weeks training. In the left muscle strength change at Centaur 45°, Feldenkrais method group and combined training group showed significant increase after 8 weeks training compared to before training and after 4 weeks training. Also elastic band training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and elastic band training group significantly increased after 8 weeks training compared to before training. In the left muscle strength change at Centaur 90°, Feldenkrais method group and combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group showed significant increase after 4 and 8 weeks training compared to before training, and elastic band training group significantly increased after 8weeks training compared to before training. In the left muscle strength change at Centaur 135°, there was no significant changes. In the right muscle strength change, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the left muscle strength change at Centaur 180°, combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, combined training group showed significant increase after 4 and 8 weeks training compared to before training. From above results, applying 8 weeks regular program of Feldenkrais method, elastic band training and combined training to modern dance majors showed positive changes on improvement of trunk muscle strength and physical strength. Also this study implemented to verify the effects of trunk muscle strength and body balance through supplementary training program, and showed the effects in the training group and control group after 8 weeks trunk muscle strengthening program. Feldenkrais method, elastic band training and combined training are very effective to improve trunk muscle strength of modern dance majors so that continuous implementation and application of these effective training program shall be provided for strengthening trunk muscle.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

N/A Background: According to the rapid changes in social environment such as increasing alcohol consumption and the marked improvement in diagnostic technique, we expect that there have been major changes in various aspects of acute pancreatitis during the recent 12 years in Korea. Methods: The medical records of 317 patients with acute pancreatitis diagnosed from 1980 through 1992 were reviewed about clinical, laboratory and radiological findings in the three different time period. Results: 1) There has been an increasing incidence in male sex about three folds. 2) There has been an increasing trends in the duration of hospitalization. 3) A significant increase was observed in the proportion of patients with alcoholic pancreatitis in the three different time period; 26.9%, 45.7%, 50.7% respectively. 4) The complication rates have been slightly increased in the three different time period; 46.3%, 47.1%, 59.1% respectively. But, the type of complications has not been changed. 5) There is increasing severity in non-gallstone group, but no significant differences in gallstone group. There is a declining trends in the number of patients with muld severity index, but increasing trend in the number of patients with moderate severity index in non-gallstone group. 6) There was no significant differences in mortality rate. Conclusions: There has been major changes in the etiology ans severity of acute pancreatitis from 1980 through 1992. Especially, significant increase in the proportion of patients with alcoholic pancreatitis was observed in the three differnt time period. These results might be due to socioeconomic changes.

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.

( Geun-hwi Park ),( Woo-il Kim ),( Min-young Yang ),( Won-ku Lee ),( Tae-wook Kim ),( Sung-min Park ),( Hyun-joo Lee ),( Gun-wook Kim ),( Hoon-soo Kim ),( Hyun-chang Ko ),( Byung-soo Kim ),( Moon-bum 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.

Effect of Total Hip Arthroplasty on Ipsilateral Lower Limb Alignment and Knee Joint Space Width: Minimum 5-Year Follow-up

Choi Yun Seong,Park Jung-Wee,Kim Tae Woo,Kang Kee Soo,Lee Young-Kyun,Koo Kyung-Hoi,Chang Chong Bum 대한의학회 2023 Journal of Korean medical science Vol.38 No.20

Background: This study aimed to 1) assess the effect of total hip arthroplasty (THA) on coronal limb alignment, namely, the hip–knee–ankle angle (HKA), 2) identify factors that determine changes in the HKA, and 3) determine whether alignment changes influence the knee joint space width. Methods: We retrospectively evaluated 266 limbs of patients who underwent THA. Three types of prostheses with neck shaft angles (NSAs) of 132°, 135°, and 138° were used. Several radiographic parameters were measured in the preoperative and final radiographs (at least 5 years after THA). A paired t-test was used to confirm the effect of THA on HKA change. Multiple regression analysis was performed to identify radiographic parameters related to HKA changes following THA and changes in knee joint space width. Subgroup analyses were performed to reveal the effect of NSA change on the HKA change, and the proportion of total knee arthroplasty usage and changes in radiographic parameters between maintained joint space and narrowed joint space groups were compared. Results: The preoperative mean HKA was 1.4° varus and increased to 2.7° varus after THA. This change was related to changes in the NSA, lateral distal femoral angle, and femoral bowing angle. In particular, in the group with a decrease in NSA of > 5°, the preoperative mean HKA was largely changed from 1.4° varus to 4.6° varus after THA. The prostheses with NSA of 132° and 135° also led to greater varus HKA changes than those with an NSA of 138°. Narrowing of the medial knee joint space was related to changes in the varus direction of the HKA, decrease in NSA, increase in femoral offset. Conclusion: A large reduction in NSA can lead to considerable varus limb alignment after THA, which can have adverse effects on the medial compartment of the ipsilateral knee.

Experimental model of hepatic fibrosis is importent contributions to the understanding of cellular and molecular mechanisms underlying excessive accumulation of extracellular matrix in the liver. Carbon tetrachloride (CCl₄) is one of the oldest and most widely used toxin for experimental induction of hepatic fibrosis in laboratory animals. In this study, We intended to induce the hepatic fibrosis in the rat by the intragastric CCl₄/ phenobarbtal treatment once a week for 12 weeks and the administration dosage of CCl₄ in each week was determined by the daily body weight change. Liver function and histologic change were examined just after 12-week treatment in group Ia (9 rats, Phenobarbital treatment only) and II (18 rats, CCl₄/phenobarbital treatment), and liver function and the irreversibility o histologic change were examined 12 weeks after 12-week treatment in group Ib (9 rats, phenobarbital treatment only) and III (18 rats, CCl₄/phenobarbital treatment). 1) Death rate after 12-week treatment was 11% in group Ⅰ, 56% in group Ⅱ and 50% in group Ⅲ. and the highest rate was at 1 week. that is 33 o each in group Ⅱ and Ⅲ. 2) Tatal protein, alkaline phosphatase, alanine aminotransferase and portal venous pressure were significantly increased in group Ⅱ compared with that in group Ⅰa, but it was only portal venous pressure that was increased in group Ⅲ than in group Ⅰb, 3) The gross finding of micronodular change was shown in 88% of group Ⅱ, 71% of group Ⅲ, but none of group Ⅰ. The microscopic finding of hepatic fibrosis was found in all of group Ⅱ and Ⅲ, but none of group Ⅰ. The severe form of hepatic fibrosis suggesting cirrhosis was found in group Ⅱ and Ⅲ, 12% and 29% respectively. In our study, mortality rate was high within 1 week after CCl₄ treatment, which resulted in half survival rate after 12-week treatment. We also experienced the loin rate of severe fibrotic changes in surviving rats. In the future, in order to produce a severe irreversible fibrotic change with low mortality in inducing hepatic fibrosis with CCl₄/phenobarbital treatment in the rat, adequate detemination of the initial dose of CCl₄ and appropriate choice of administration route of CCl₄ were thought to be needed.

Case Report : A Case of Occupational Hypersensitivity Pneumonitis Associated with Trichloroethylene

( Young Jae Kim ),( Eu Dong Hwang ),( Ah Young Leem ),( Beo Deul Kang ),( Soo Yun Chang ),( Ho Keun Kim ),( In Kyu Park ),( Song Yee Kim ),( Eun Young Kim ),( Ji Ye Jung ),( Young Ae Kang ),( Moo Suk 대한결핵 및 호흡기학회 2014 Tuberculosis and Respiratory Diseases Vol.76 No.2

Trichloroethylene (TCE) is a toxic chemical commonly used as a degreasing agent, and it is usually found in a colorless or blue liquid form. TCE has a sweet, chloroform-like odor, and this volatile chlorinated organic chemical can cause toxic hepatitis, neurophysiological disorders, skin disorders, and hypersensitivity syndromes. However, the hypersensitivity pneumonitis (HP) attributed to TCE has rarely been reported. We hereby describe a case of HP associated with TCE in a 29-year-old man who was employed as a lead welder at a computer repair center. He was installing the capacitors on computer chip boards and had been wiped down with TCE. He was admitted to our hospital with complaints of dry coughs, night sweats, and weight losses for the past two months. HP due to TCE exposure was being suspected due to his occupational history, and the results of a video-associated thoracoscopic biopsy confirmed the suspicions. Symptoms have resolved after the steroid pulse therapy and his occupational change. TCE should be taken into consideration as a potential trigger of HP. Early recognition and avoidance of the TCE exposure in the future is important for the treatment of TCE induced HP.
