To find the prevalence and related factors of low back pain experienced by some beauticians. a survey was made toward 252 beauticians in Kwangju City from March 1st to April 1st, 1998. The results were as follows; 1. The prevalence rate of low back pain among the respondents for the last week was 59.5%. 2. The aid group and staff group with low back Pain had significantly longer duration of work than those without low back pain. Managers who had bad posture with twisted or too much extended back showed a significantly higher prevalence of low back pain than those with good posture during work(P<05). 3. Aid group with low back pain showed significantly higher points at total stress score, depression score, general health score and vitality score than those without low back Pain. The staff group with low back pain showed significantly higher points for total stress score, sleep disorder and anxiety score, depression score, general well-being and vitality score than those without low back pain. Managers with low back Pain showed significantly higher points of stress at social performance and self confidence (P<05) than those without low back pain. The above results suggest that low back pain is related to different jobs and work environments for beauticians. So effective measures and further studies against risk factors must be made considering their jobs. To prevent or reduce low back pain, appropriate management of stress for beauticians is necessary.

<P>Background: Nephrotoxicity associated with lead poisoning has been frequently reported in epidemiological studies, but the underlying mechanisms have not been fully described.</P><P>Objectives: We examined the role of erythrocytes, one of the major lead reservoirs, in lead-associated nephrotoxicity.</P><P>Methods and results: Co-incubation of lead-exposed human erythrocytes with HK-2 human renal proximal tubular cells resulted in renal tubular cytotoxicity, suggesting a role of erythrocytes in lead-induced nephrotoxicity. Morphological and flow cytometric analyses revealed that HK-2 cells actively phagocytized lead-exposed erythrocytes, which was associated with phosphatidylserine (PS) externalization on the erythrocyte membrane and generation of PS-bearing microvesicles. Increased oxidative stress and up-regulation of nephrotoxic biomarkers, such as NGAL, were observed in HK-2 cells undergoing erythrophagocytosis. Moreover, TGF-β, a marker of fibrosis, was also significantly up-regulated. We examined the significance of erythrophagocytosis in lead-induced nephrotoxicity in rats exposed to lead via drinking water for 12 weeks. We observed iron deposition and generation of oxidative stress in renal tissues of lead-exposed rats, as well as the histopathological alterations such as tubulointerstitial lesions, fibrosis, and up-regulation of KIM-1, NGAL, and TGF-β.</P><P>Conclusions: Our data strongly suggest that erythrophagocytosis and subsequent iron deposition in renal tubular cells could significantly enhance nephrotoxicity following lead exposure, providing insight on lead-associated kidney damages.</P><P>Citation: Kwon SY, Bae ON, Noh JY, Kim K, Kang S, Shin YJ, Lim KM, Chung JH. 2015.

Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

Purpose: The present study purposed to compare the hand washing effect of 7.5% powidone-iodine, which is used in the operation room of C university hospital in Seoul, with that of Ethyl alcohol-CHG mixture recommended by the US Association of Operating Room Nurses (2002) and to adopt a more effective hand disinfectant. Method: In a quasi-experimental design, 48 medical staff who participated in operations during the period from November 2004 to February 2005 had hand washing using the two kinds of hand disinfectants: 7.5% povidone-iodine and the ethyl alcohol-CHG mixture. Their palms were swabbed and cultured just after hand washing and again after taking dff sterile gloves after the operation. The number of colonies from the two occasions were counted and compared. Result: The number of general bacillus increased significantly in the group using 7.5% povidone-iodine compared to that in the group using the ethyl alcohol-CHG mixture. The number of general bacillus increased signficantly in doctors compared to that in nurses. The factors affecting the increase of the number of general bacillus were disinfectants and medical personnel. The number of general bacillus was expected to increase 9.41 times with 7.5% povidone-iodine than with the ethyl alcohol-CHG mixture and 14.87 times in doctors than in nurses. Conclusion: This study shows that the ethyl alcogol-CHG mixture has a stronger hand disinfection effect than 7.5% povidone iodine. Thus we need to change the hand disinfectant used in operating rooms as soon as possible in order to minimize the infection of wounds resulting from operations.

The study was conducted to evaluate the difference of life style, subjective symptoms and health cognition depending on the Sasang Constitution in the industrial workers. The results were as follows ; Constitutional distribution among exposed group were Tae-eum In(38.4%), So-eum In(35.2%), and So-yang In(26.4%) and it was turned out that Tae-eum In took a higher portion of Sasang constitution than other constitutions in technician workers. 'Exercise' and 'Obesity' were found most in Tae-eum In, In So-eum In there were many 'Normal' weight and 'Having digestive disorders' were found most in So-eum In. There were no significant difference in the health cognition among the constitutions. The closer to 'normal' weight, the higher prevalence in 'having' concern about health condition and the more 'normal' condition in sleeping, the higher prevalence of 'having' self-confident in present health.

Using of steel box girder bridges have been used a tendency to increase for workability and economic reasons. For maintenance and management of these bridges, manholes are needed for route. (But installation of manholes causes a loss of area of section. It is developed with stiffness down and stress concentration.) By way of prevention, it is reinforced with attachments and stiffeners or its shape strengthened by as aspect in geometry. Sometimes it is over-estimated and excessive reinforcing at a welding cost follows. In this paper, both experimental and analytical results are performed to verify the behavior of a steel box girder bridge under increasing dead loads. Furthermore, there is some structural analysis on several manhole types of diaphragm, which reflect the real effect of the support. The presentation in this paper is ultimately the most reasonable and economical reinforcing method for the manhole of a diaphragm is a steel box girder bridge.

The ulnar nerve extends down the arm, across the elbow, and into the hand. It provides sensation to the little and ring fingers and activates many of the small muscles in the hand. The determination of peripheral nerve conduction velocity is an important part of ulnar nerve evaluation. The electrodiagnostic value as neurophysiologic investigative procedure has been known for many years but normal value of digital nerve was not reported in korea. The purpose of this investigation was to measure the digital nerve conduction velocity of ulnar nerve for obtain clinically useful reference value and compare difference in each fingers and then compare with the other countries. 71 normal Korean volunteers (age, 19-65 years; 142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrinedisorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking Ⅱ(EMG machine) was use for detected conduction velocity and amplitude of digital nerve in ulnar nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation and independent t-test was used to compare with ring and little finger. Conduction velocity of the right ring finger was 57.44m/sec and little finger was 55.32msec. The left ring finger was 55.55msec and little finger was 54.11msec. Amplitude of the right ring finger was 30.28µV and little finger was 48.36µV. The left ring finger was 30.67µV and little finger was 57.76µV. There were significantly difference between ring and little in amplitude (p<.05) but there were no statistically difference between conduction velocity of ring and little finger (p>.05). The amplitude of little finger are greater than ring finger. The present results revealed that electodiagnosis can easily perform in little finger for digital nerve of ulnar nerve study.

〈Objective〉 This study were carried out to study to assess the relationship between job characteristics, general characteristics, health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. 〈Methods〉 We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item self- administered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) 〈Results〉 Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12~4.11), and those of passive group and active group were 2.01(95 0.83~2.76) and 1.80(95 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. 〈Conclusion〉 The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.
