Objectives : The purposes of this preliminary study was to examine the feasibility of recruiting women into a clinical trial designed to examine the effects of acupuncture in treating urinary incontinence (UI) in premenopausal women with delivery history and the feasibility of performing the study procedures. We also tried to determine if there was preliminary evidence to suggest that acupuncture may be effective in reducing UI and improving disease-specific quality of life. Methods : This study was a pragmatic randomized clinical trial. Subjects between the ages of 20 and 49 years were randomly assigned to a treatment(n=11) or control group(n=11) and analyzed. Both groups were supposed to do Kegel exercise at home during 4 weeks and acupuncture was applied to the treatment group twice a week(8 sessions) additionally. Subjects performed 1 hour pad test and completed a 3-day urination diary, international consultation on incontinence modular questionnaire(ICIQ), and incontinence - quality of life(I-QOL) at base line and 5 weeks. Results : Both group showed improvement in 1 hour pad test and the reducing amount of UI was significantly larger in treatment group(p=0.0182). The significant improvements in ICIQ and I-QOL were also observed in treatment group and sustained until the follow-up measurement at 16 weeks. Any adverse reaction related to acupuncture did not happen. Conclusions : It was feasible to recruit subjects and perform the study procedures. The positive results of this study support the requirement for additional research investigating the efficacy of acupuncture in the treatment of UI in women.

Purpose: The purpose of this study was to identify the effects of meridian massage on menopausal symptoms and Shin-Hur in middle-aged menopausal women. Method: The research design was a nonequivalent control group pre-post experimental design. The subjects of the study were middle-aged women who had had no menstruation in the last 12 months after the last menstrual bleeding. Cards of invitation on bulletin boards of several apartments were placed to recruit the subjects. The cards of invitation included: purpose of the study, eligibility criteria, method and period. Eighteen women in the experimental group and 16 women in the control group were conveniently assigned, respectively. The experimental group received 20 min meridian massage 3 times per week for 4 weeks. The menopausal symptoms and Shin-hur were measured and compared between the two groups before and after the intervention. Data were analyzed with the SPSS program by Fisher's exact test, Wilcoxon Sign Rank test, Mann Whitney U-test and Spearman's rank correlation. Result: The experimental group showed a significant decrease of menopausal symptoms (U=77.00, p=.020) and Shin-Hur (U=76.00, p=.017). There was a significantly positive correlation between menopausal symptoms and Shin-Hur (r=.497, p=.003). Conclusion: Meridian massage was effective in improving menopausal symptoms and Shin-Hur in middle-aged menopausal women. Thus it can be useful as a nursing intervention for menopausal women.

Objective : The purpose of this study was to analyse the differences in core stability and muscle balance of the pilates Teaser motion according to the surfaces and skills. Methods : There were 10 subjects in this study with 5 being skilled and 5 that were not skilled. The independent variables were surfaces (high elastic & aluminum) and skills (skilled & unskilled). Dependent variables were core stability and muscle balance. Core stability was measured by Force Platform (9872, Switzerland), 3D Imagery (IBS-2000, EXYMA) was used to understand the muscle balance. In order to do the Teaser movement subjects had to lay flat on their back and then lean forward as much as possible and hold the position for 10 seconds. Afterwards, they would lay back down again. A camera (MHS-PM5K, SONY) was used to make 4 phases (take off, recoil forward, holding, recoil backward) during the teaser exercise to analyze movement. In this study quantitative and qualitative analysis was used. For the statistical analysis, 2X2 ANOVA was used to analyze the differences in movement time, X,Y,Z maximum force, center of pressure and angles according to different phases. 2X3 ANOVA was used to analyze the differences in muscle balance via SPSS 18.0. Results : Soft. Elastic mat had a longer holding time, lower Fx/ Fy/ Fz, shorter Fx trajectory, larger angle and shorter gaps in muscle balance than a hard surface in skilled subjects. This was because the mat can help to recruit and then sustain core fine muscles during holding time in the Teaser movement.

Purpose: This study aimed to compare the immediate effects of various contract-relax (CR) techniques on the peck force and passive range of motion (ROM) of knee extension. Methods: This study recruited 17 adult males and females who obtained below $90^{\circ}$ in straight leg raising. The subjects randomly performed one of three different CR techniques (direct CR, indirect CR, and modified CR) on the right knee extension four times per day for three days. The subjects' peck force during each CR and their passive knee extension on the hip at a $90^{\circ}$ flexed position before and after each CR were measured. Results: The peck force was significantly higher in the direct and modified CR than in the indirect CR. The ROM in the passive knee extension significantly increased after direct and indirect CR. Comparing between each CR, the passive knee extension range was significantly more improved in the direct and indirect CR than in the modified CR. Conclusion: Direct and indirect CR are more effective than modified CR in the ROM of passive knee extension. The study results suggest that the modified CR did not have the same effect on the ROM of the knee extension as the direct and indirect CR and that further research is needed to recruit more subjects and to determine the effects on different muscles after modified CR.

This study is to develop the model on the joint employment system of occupational health nurse practitioners for medium or small sized enterprises in Korea based on the comparison opinions between employers and occupational health nurses (OHN). The data were collected by questionnaires from Oct. to Nov. in 1997. The number of subjects was 210 OHNs and 176 employers, response rate was 47.1% for OHNs and 23.2% for employers. The SAS PC program was used for the descriptive statistics. The results were as follow: 1. More than three years career was preferred for qualification of OHN by employers and OHNs. OHNs preferred that all instruments and materials should be equipped in each industry, but employers preferred that they should be equipped by OHN. 2. For the limit number of industries and employees per one OHN, employers preferred average 2.25 industries and 307 employees, OHNs preferred average 3.0 industries and 448 employees. Both of them preferred two times visit per week for all day long. 3. OHNs wanted that the local office of Ministry of Labor could act as mediator, but employers preferred direct contact individually. For the average wage, employers preferred 887,000 won per month, but OHNs preferred 1,960,000 won per month. 4. OHNs preferred the Korean Association of Occupational Health Nurse as the recruit agency. Finally, employers and OHNs have the opinions that they can choose this system depending on the condition. There is in need of development of effective strategy for this new system such as manpower development, cost-benefit analysis, establishment of occupational health service standard, advertisement for employers, and government supported project.

Purpose: The purpose of this study was to analyze the frequency and patterns of intra-articular lesions detected during ankle fracture surgery using ankle arthroscopy. Materials and Methods: Thirty patients (31 ankles) who underwent open reduction and internal fixation combined with ankle arthroscopy for acute ankle fracture at Inje University Busan Paik Hospital from June 2011 to September 2013 were evaluated. The ankle fractures were classified according to the AO/OTA (AO Foundation and Orthopaedic Trauma Association) classification and the intraarticular injuries were identified by ankle arthroscopy. Osteochondral lesions of the talus were divided into nine subtypes based on their locations, and the ligament injuries were classified according to avulsion fracture and rupture. Results: Using arthroscopy, abnormality in the distal tibiofibular ligament was found in 21 cases and osteochondral lesions and defects of the talus larger than 5 mm were detected in 26 cases. Among ligament injuries, anterior inferior tibio-fibular ligament injury was found in 14 cases, posterior inferior tibio-fibular ligament injury was found in two cases, deep deltoid ligament injury was found in three cases, and deep transverse tibio-fibular ligament injury was found in five cases. The locations of the osteochondral lesions were on the antero-lateral, antero-medial, centro-medial, centro-central, centro-lateral, and postero-lateral talus in 11, one, two, one, two, and nine cases, respectively. Conclusion: With early diagnosis and treatment arthroscopy performed at the time of intra-articular fracture surgery is expected to result in a good outcome.

An objective of this study is to give practical information that could be used for calculating pollutant emission factors and fuel economy from Korean Inspection & Maintenance program, which has been using steady state acceleration simulation mode. Concentration results from I/M test is adequately converted to mass emission factors and fuel efficiency data, which have unit of g/km and km/L, respectively. Exhaust volume flow(EVF), which is for converting emission result from concentration to mass, is measured by tracer method in various vehicle speed - power condition. It is found that there is an apparent second order relationship between EVF and vehicle inertia weight. EVF is expressed in function of vehicle inertia weight in order to estimate EVF in I/M site without measuring device. Converted mass emission results from measured EVF and raw emission analyzer show a satisfactory agreement with those from conventional CVS-bag type measurement system. Mass emission factors and fuel efficiency from measured EVF and estimated EVF also show good agreement to each other. Considering that an I/M program has great advantages to recruit-based emission test in terms of the number of test vehicle, the information in this study can be used for developing an alternative procedure to collect more various data to establish national database of mobile emission factors and fuel economy, even though the driving cycle in I/M program is steady state cycle rather than transient cycle.
