        The cumulative trauma disorder is a disease group of musculoskeletal systems developed by repeated work, which became greate concern in occupational health problem in Korea recently. Many paramedicals working in the department of Laboratory, Radiology, and Rehabilitation of the hospital have been engaged in the simple repetitive hard works causing cumulative trauma disorder. This is the study on the cumulative trauma disorder in those medical technicians. Total 285 (180 male, 105 female) medical technicians and office workers working in the hospital were surveyed with the self-administered questionnaires. They included the questions such as age, sex, marital status, education, height, weight, smoking and drinking history as a general characteristics and work department, kind of work, work duration, work conditions as a work characteristics. And also subjective symptoms related with the work in each region of body area were questioned. Among the work conditions, there were significant differences between medical technicians and office workers (e.g., high in medical technicians) in daily works lifting patients or heavy equipments, works moving continuously and rapidly, works with uncomfortable position, works keeping neck and upper arms in uneasy position. Complained rate of subjective symptoms was significantly higher in physical therapist and in the group of work duration over 10 years. The significant symptoms were pain, abnormal sensation, burning sensation. The significant factors affecting the subjective symptoms were female and work duration over 10 years for wrist area, female and current smoking for knee or ankle area, physical therapist, work duration between 6 and 9 years for lumbar area, female and radiologic technicians and work duration over 6 years for shoulder area. None was significant for neck area.

        Cardiac Damage Biomarkers Following a Triathlon in Elite and Non-elite Triathletes

        박찬호,김귀백,한진,지진구,곽이섭 대한약리학회 2014 The Korean Journal of Physiology & Pharmacology Vol.18 No.5

        The purpose of the present study was to investigate cardiac damage biomarkers after a triathlonrace in elite and non-elite athlete groups. Fifteen healthy men participated in the study. Based onperformance, they were divided into elite athlete group (EG: n=7) and non-elite athlete group (NEG:n=8). Participants’ blood samples were obtained during four periods: before, immediately, 2 hours and7 days after finishing the race. creatine kinase (CK), creatine kinase-myoglobin (CK-MB), myoglobin,and lactate dehydrogenase (LDH) were significantly increased in both groups immediately after, and2 hours after finishing the race (p< .05). CK, CK-MB, and myoglobin were completely recovered after7 days (p< .05). Hematocrit (Hct) was significantly decreased in both groups (p< .05) 7 days after therace. LDH was significantly decreased in the EG (p<.05) only 7 days after the race. Homoglobin (Hb)was significantly decreased in the NEG (p<.05) only 2 hours after the race. Although cardiac troponinT (cTnT) was significantly increased in the EG but not in the NEG 2hours after the race (p< .05),there was no group-by-time interaction. cTnT was completely recovered in both groups 7 days afterthe race. In conclusion, cardiac damage occurs during a triathlon race and, is greater in elite thanin non-elite. However, all cardiac damage markers return to normal range within 1 week.

        Fractionation of Gelatin Hydrolysates with Antioxidative Activity from Alaska Pollock Surimi Refiner Discharge

        박찬호,김준,강경태,박주동,허민수,박재원,김진수 한국수산과학회 2009 Fisheries and Aquatic Sciences Vol.12 No.3

        This study was conducted to obtain the gelatin fraction with a high antioxidative activity from Alaska pollock surimi by-products using a two-step enzymatic hydrolysis and ultrafiltration. Among gelatin hydrolysates from refiner discharge of Alaska Pollock surimi, the highest antioxidative activity (81.5%) resulted from gelatin hydrolysate sequentially treated with Pronase E and Flavourzyme each for 2 hr. However, no difference was seen in the antioxidative activity of the second hydrolysate (Pronase E-/Flavourzyme-treated hydrolysate) when compared to the permeate fractionated through a 10-kDa membrane. The results suggest that the Pronase E-/Flavourzyme-treated hydrolysate from refiner discharge gelatin of Alaska pollock surimi can be used as a supplementary raw material for improving health functionality.

        Fractionation and Angiotensin I-converting Enzyme (ACE) Inhibitory Activity of Gelatin Hydrolysates from by-products of Alaska Pollock Surimi

        박찬호,김형준,강경태,박재원,김진수 한국수산과학회 2009 Fisheries and Aquatic Sciences Vol.12 No.2

        Gelatin hydrolysates with a high inhibitory activity against angiotensin I-converting enzyme (ACE) were fractionated from Alaska pollock surimi refiner discharge. The ACE-inhibitory activity, expressed as IC50 (mg/mL), was highest (0.49 mg/mL) in gelatin hydrolysates formed by sequential 2-hr treatments of Pronase and Flavourzyme. After fractionation through four different membrane filters with molecular weight cut-offs of 3, 5, 10, and 30 kDa, the highest ACE-inhibitory activity (0.21 mg/mL) was observed with the 3-kDa filtrate.

        To estimate the effects of environmental noise on inhabitants' life in an apartment area at Taejon, noise levels and traffic volume of major roads were measured. 203 housewives were surveyed by questionaires including general factors, noise related factors and three items of life effects: subjective evaluations on the general environment, annoyance, and life disturbance due to environmental noise. At the boundary adjacent to the road with more traffic volume, noise level was higher; according to the time, the amount of noise level was in the morning, in the evening, at noon, and at night in order. Most of boundary noise levels were higher than those of recommended standard environmental noise levels in a residential area. The boundary noise level showed a very significant linear relationship with traffic volume of near roads. Noise level difference in the apartments adjacent to three roads was ranged 2.4~6.7dB between in windows open and close state. The apartments adjacent to 9 lane or 6 lane-road, which were protected by noise prevention wall and 20m or more distance from the roads, showed higher noise level at middle floors and high floors than those of low floors; but the buildings adjacent to 4 lane-road, with no protection, showed higher noise level at low and middle floors than those of high floors. Among 203 housewives, 120(59.1%) participated in this study, and 86(73.2%) of them answered that the most serious environmental noise was traffic noise from near roads. Comparing traffic noise levels with those of before-migration, 67.0% participants found the environmental noise became louder. Fifty eight(49.5%) of the participants wanted noise protection wall and 15(25.9%) of them were willing to charge the fee. Less perception on the present noise comparing to those before-migration, less traffic volume, and lower noise levels in the apartments were related to higher scores of self-evaluation on the environment. Higher susceptibility on the present noise, areas with more traffic volume, higher boundary noise levels, and higher noise levels showed higher scores of annoyance on environmental noise and life disturbance. Considering above all things, it was suggested that traffic noise in this area was the major problem of environmental noise, and its' effect was so serious that inhabitants needed some preventive measures for better life quality.

        Development of the Bias-Cut Dress Pattern Making Method by Applying Fabric Draping Ratio

        박찬호,천종숙 복식문화학회 2012 服飾文化硏究 Vol.20 No.4

        This study aimed to investigate a bias pattern making method with geometrical approach. The bias-cut dress has soft silhouette of drape in the garment. However, the bias cut dress has problem of satisfying the intended garment size spec. This problem occurs from various sources. The main reason is that the bias-cut fabric tends to stretch on longitudinal direction and to shrink horizontal direction when it was hung on the body. The goal of this study was to develop a bias-cut dress pattern making method satisfying the intended garment size spec. The researchers developed the geometrical method of measuring dimensional change by calculating the compensation ratio of the fabric in true bias direction. The compensation ratio was calculated by applying draping ratio of the fabric. Three types of fabrics were used in the experiment. The warp and weft crossing angle of fabric was ranged from 78° to 82°. The fabrics stretched longitudinally 6.9~9.9% and shrank horizontally 7.2~11.0%. The compensation ratio of the bias-cut pattern for sample dress was calculated for each fabric type. Two types of experimental bias-cut dress patterns were developed for each fabric. One pattern was made with applying full compensation ratio and the other one made with applying partial ratio of the fabric. Experimental dresses were made with these patterns. The results of the evaluation showed that the bias-cut dress pattern applying the partial compensation ratio was more appropriate than the pattern applying the full compensation ratio.

        Lower Urinary Tract Infection and Periprosthetic Joint Infection after Elective Primary Total Hip Arthroplasty

        박찬호,이영균,구경회 대한고관절학회 2017 Hip and Pelvis Vol.29 No.1

        Purpose: Periprosthetic joint infection (PJI) after total hip arthroplasty (THA) is a grave complication. Urinary tract infection (UTI) as a source for PJI is controversial. Our purposes were, (1) to evaluate the incidence of PJI after elective primary THA and (2) to determine whether UTI was associated with a risk of PJI after elective primary THA. Materials and Methods: We retrospectively reviewed the medical records of 527 patients who underwent elective primary THA by using universal aseptic technique from May 2003 to October 2007. UTI group (13 patients) was defined as patients who underwent THA in status of having an UTI, and the remaining patients were defined as control group (514 patients). We compared the incidence of PJI in both groups. Results: During the study period, the incidence of PJI was 0%, regardless of existence (or presence) of UTI. Conclusion: There was no significant association between UTI and PJI, when cautiously performed THA.

        淸州 父母山城 貯水槽의 性格

        박찬호,성정용 백제학회 2019 백제학보 Vol.0 No.30

        In the Cheongju area, ancient ruin reflecting the traces of the long fierce battle from The Proto-Three Kingdom Period to the Unified Silla Period were found everywhere.In particular, the Sam-yeon fortresse and Yang-sung fortresse, built by Silla in the late 5th century, prove that Cheongju and Boeun regions represent the aspects of the turbulent period. Along with the Sam-yeon Fortress and Yang-sung Fortress, Cheongju Bu-mo Fortress has been recognized by academic circles as a ruins symbolizing Silla's advance into the Jungwon area. However, when the Chungbuk National University museum excavated the first bastion and the Hak-cheon Fortress in the southwestern part of the Bu-mo fortress, researchers suggested that they had been built by Baekje, leading to views that Silla and Baekje might have created tension over their Bu-mo fortress. In this regard, considerable quantities of Silla relics from around the 6th century or so were excavated from the water facilitiy located at the top of the Bu-mo fortress, showing the construction and operation of the fortress. Contrary to the preceding comments, only two pieces of earthen pots from Baekje were identified in this water facility. Considering the possibility that Baekje had taken the castle and the timing of the excavated relics, Silla is highly likely that the water facilitiy had already been disposed of before Baekje took it. What’s more, this water facilitywas in the form of a circular staircase, and This type of water facility were mostly found in the Silla region. Therefore, based on the structural features of the water facility and its review of the relics excavated from it, we will briefly take a look at the historical meaning of the water facility. 청주 일원에서는 그간 원삼국시대부터 통일신라에 이르는 긴 쟁탈기의 흔적을 반영하는 유적들이 곳곳에서 확인되었다. 특히 신라가 5세기 후반에 축조한 삼년산성(470)과 양성산성(474)은 청주와 보은지역 일대를 둘러싼 격변기의 양상을 대변하고 있다. 청주 부모산성은 삼년산성 및 양성산성과 더불어 그간 학계에서는 신라의 중원 진출 시기를 상징하는 유적으로 인식되어 왔다. 그런데 부모산성 남서쪽의 제1보루와 학천산성이 백제에 의해 축조되었다는 주장들이 발굴조사 결과 제기되면서, 부모산성 또한 신라와 백제가 탈환과 재탈환을 반복하는 각축장이 되었을 것으로 보는 견해들이 많아졌다. 이와 관련하여 부모산성 정상부에 위치한 저수조에서 6세기대 신라계 유물이 상당량 출토된 점은 산성의 축조 및 운영과정 등에 시사하는 바가 많다고 생각된다. 앞의 지적과 달리 이 저수조에서 백제 토기는 동이 2점만이 확인되었을 뿐이다. 만약 백제가 부모산성을 함락했을 가능성을 전제한다면, 저수조 출토유물의 시기를 고려할 때 신라는 이 성을 빼앗기기 전 저수조를 폐기했을 가능성이 있다. 더욱이 이 저수조는 원형 평면에 계단식으로 축조된 것으로서, 신라지역에서 확인되는 원형 석축 저수조들과 구조가 유사하다. 본고에서는 이 부모산성 저수조의 구조적 특징과 출토유물에 대한 검토를 토대로 이 저수조가 갖고 있는 사적 의의를 간단히 살펴보고자 한다.
