Injuries to the menisci occur in a variety of ways, most commonly with a twist, pivot, squat, or valgus stress to the knee. Tear patterns are classified to longitudinal, horizontal, or transverse features according to the mechanism of injury. Work-related meniscal tear usually occurs with a repetitive usage of the foot, hence it can be classified as a cumulative traumatic disorder. We found a 47 year-old female worker who had been taking charge of repetitive foot-switch stepping for 8 years. She suffered from pain in the right knee since 5 months ago. Tenderness along the medial joint line of the right knee was observed and pain was aggravated with full flexion of the right knee. On magnetic resonance imaging, high signal intensity was observed at the posterior horn of the medial meniscus of the right knee. Degenerative longitudinal and transverse complex tear in the medial meniscus was observed on arthroscopy. Arthroscopic partial meniscectomy was performed. We surveyed the work process and the health status of co-workers. It turned out that the work process was compatible to injure the meniscus and nine out of fourteen co-worker(64.3%) complained pain of the knee. No other factors related to her meniscal tear could be found except for the situation at her work. Therefore, we conclude that meniscal tear is related to the repetitive stepping of foot switch.

Objective: The purpose was to investigate changes in mechanical properties, range of motion, and grip strength of the forearm muscle in 13 students depending on the wrapping direction of the floss band. Design: A single-blind, crossover study Methods: Subjects were randomly assigned to the wrapping direction of the flossing band and then performed a concentric exercise of the wrist flexors using a Flex-Bar. Intervention A applied the flossing band in a right spiral direction, Intervention B applied the flossing band in a left spiral direction, and Intervention C performed the exercise alone. All subjects used their dominant right hand, and pre- and post-assessments were conducted between interventions. To analyze differences in changes between groups pre- and post-, all results were subjected to one-way ANOVA, followed by Scheffe's test as a post-hoc analysis. The paired samples t-test was used to analyze the difference between pre- and post-change within groups. Results: First, in the mechanical properties of the Flexor carpi ulnaris (FCU) muscle, interventions A and B significantly improved muscle tone and stiffness than intervention C (p<0.05), and intervention A showed a significant decrease in decrement (muscle elasticity) than intervention B (p<0.05). Second, interventions A and B showed significant improvement in grip strength than intervention C (p<0.05). Conclusions: The right spiral direction of the flossing band tended to increase the elasticity of the muscles compared to the left spiral direction. Therefore, in future studies, it is necessary to choose the direction of the flossing band to increase the elasticity of the muscles.

The purpose of this study is to determine cardiovascular reponses to concentric, eccentric and isometric exercise applied to the knee extensor muscle group. Exercise types studied were concentric, eccentric and isometric. The subjects were sixty healthy male volunteers who had no hypertension or cardiac disease. Heart rate, systolic and diastolic blood pressure were recorded prior to starting exercise. The subjects also performed 10RM on right lower extremity. A N-K table was used for three exercises to right knee extensors. Each exercise was selected randomly and applied to each subject 10 times in a 10 second. After each exercise, heart rate, systolic and diastolic blood pressure were recorded immediately. Findings were as follows concectric contractions had a greater effect on the increase of systolic blood pressure and heart rate than eccentric or isometric contractions. Diastolic blood pressure is influenced only by isometric contractions. Eccentric contractions have less effect on the increase of systolic blood pressure and heart rate than concentric or isometric contractions. We hope that the results of this experiment can be adapted to exercise programs for patients with cardiac disease.

Building materials have a great impact on the health of a building's occupants. Thus, it is imperative that their health-related properties be taken into during the course of construction project. Unfortunately, no current database system exists that can provide information on the health performance of building materials at each stage of construction project management, from planning and design to building and maintenance. therefore, an inordinate amount of time and effort is required to choose the right health-friendly materials(DBHM). To solve this problem, this study aims at building a database management system for health-friendly building materials. It analyzes the health-related properties and performance of various materials, and proposes a database structure and operation algorithm. The system proposed in this study is expected to contribute to the objective evaluation of health-friendly building materials through the accumulation of relevant data.

Man pursues health as his basic right. Therefore, the government should try to preserve the right of the people's health and carry out the policy of medical treatment for that. But the system of our medical care is advantageous to the medical institutions, which produce medical goods each people buys and sells freely, more than to the maintenance and improvement of their health. That is to say, the first aim of the institution is not the healthy preservation of the people but their accumulation of riches. The medical conflicts are the social situation which is happening between those who produce medical treatment and the patients who consume it. Its behinning comes from the lack of belief by the inhuman relationship between patients and doctors. According to thelatest investigation, the patients of oriental clinics look more content than those who go to common hospitals. The reasons are as follows; fitness to one's physical constitution, the kind altitude of doctors and the view of oriental medicine toward human body. Though the content degreee is higher than western medicine, such conclusions result from the present condition the number of the patients is less. In short, the first, since the right of patients is higher and the fields make more variors and popular, the conflicts and mistakes go on increasing. The second, in their activity of treatment, the legal importance of atlention and explanatory obligation should be considered seriously so as not to break out medical mistakes. The third, in the center of technical books which are accepted by the academic world, the clinical exertion doing treatment is needful. The fourth, as the direct order of medical justification the self-determination of patients should be respected. The fifth, because the process and record of treatment become important in the time of emergency legally, the conversations and movements as well as the details of treatment must be recorded. The sixth, the academic effort about the settlement institution or the legal system is necessary.

The right to petition is a classical right of the people in constitutional states, and in Korea, it is a statutory right in the Constitution, the National Assembly Law, the Petition Law, and the Local Autonomy Act. The healthcare community first made a successful petition to the National Assembly when it achieved the amendment of the Government Organization Act through a petition to the National Assembly for the independence of the Ministry of Health, and this achievement served as the basis for further petitions. Since then, the healthcare community has successfully achieved the enactment and amendment of related occupational laws through National Assembly petitions, such as the amendment of Article 41, Paragraph 7 of the former Medical Insurance Act (Korean Medical Association, 14th Assembly), enactment of the Dental Health Act (Korean Dental Association, 15th Assembly), and amendment of the Health Functional Foods Act (Korea Pharmaceutical Association, 16th Assembly). Its petition accomplishment rate is higher than the total petition accomplishment rate of the Health and Welfare Committee of the National Assembly. However, along with the overall decrease in the number of National Assembly petitions, the Korean Medical Association and Korea Pharmaceutical Association have not achieved any results through petitioning since the 16th Assembly (June 2000), and the Korean Hospital Association and Korean Nurses Association have not achieved any results through petitioning since the 17th Assembly (April 2004). Furthermore, no National Assembly petitions have been made at all for 5 years (2014-2018). The Korean Medical Association and Korea Pharmaceutical Association previously showed a high petition accomplishment rate through their accumulated experience with National Assembly petitions and vigorous policy assistance from doctors/pharmacists/nurses turned lawmakers. More specifically, healthcare organizations have achieved results by actively conducting organized activities with the National Assembly, as implemented by a national assembly director and employees, and in case of petitions for legislation, each group has established infrastructure for reviewing the relevant laws by appointing a legislative director, as well as a legal advisor and advisory counsel. Although the organization that has submitted the most petitions to the National Assembly is the Korean Hospital Association, the group with the highest petition success rate is the Korean Medical Association, which may be linked to the relatively high proportion of doctors who have become lawmakers. Furthermore, the fact that other healthcare organizations were highly interested in petitioning the National Assembly has had major implications for the petition activities of healthcare organizations.

Purpose: The purpose of this study was to evaluate the effect of the sexual education program on female college students' sexual knowledge and sexual autonomy. Methods: The integrative 5-week (15 hour) sexual education program reflecting control and coping aspects of sexual autonomy was developed based on self-determination theory. 59 female students were assigned to the experimental (n=29) and the control group (n=30). Students completed the sexual knowledge and the sexual autonomy questionnaires at prior to the program, right after and 10 weeks after the completion of the program. Independent t-test were used to test the effectiveness of the program. Results: Significant group differences were found on sexual autonomy score right after and 10 weeks after the completion of the program. No significant group differences were found on sexual knowledge at any time after the program completion. Conclusion: The results indicate that the 5-week Sexual Education Program was effective in increasing female college students' sexual autonomy. Nursing professors majoring women's health nursing may contribute to improving college students' sexual autonomy by opening the sexual education program as a general elective curriculum. Strategies to improve sexual knowledge need to be considered for better effectiveness of the program.

Background: Sexual dimorphism is important for sex determination in the field of forensics. However, sexual dimorphism is commonly assessed using cone beam computed tomography (CBCT) rather than three-dimensional (3D) modeling software; therefore, studies using a more accurate measurement approach are necessary. This study assessed the sexual dimorphism of the MS using a 3D modeling program to obtain information that could contribute to the fields of surgery and forensics. Methods: The CBCT data of 60 patients (age, 20~29 y; 30 males and 30 females) admitted to the Department of Orthodontics at the Dankook University School of Dentistry were provided in Digital Imaging and Communications in Medicine (DICOM) format. The left MS and right MS were modeled based on the DICOM files using the Mimics (version 22; Materialise, Leuven, Belgium) 3D program and converted to stereolithography (STL) files used to measure the width, length, and height of the MS, infraorbital foramen (IOF), right MS, and left MS. The average of three repeated measurements was calculated, and a reliability test was performed to ensure data reliability (Cronbach's α=0.618). A canonical discriminant analysis was performed using a standard approach (left: Box's M=0.096; right: Box's M=0.115). Results: Males had greater values for all parameters (MS width, MS length, MS height, IOF, right MS, left MS) than females. The discriminant analysis identified six independent variables (MS width, MS height, MS length, IOF, right MS, left MS) that could identify sex. The left MS and right MS correctly identified the sex of 81.7% and 71.7% of the patients, respectively, with the left MS having higher accuracy. Conclusion: This study confirmed that, for Korean individuals, the left MS has a better ability to identify sex than the right MS. These results may contribute to sex identification in the fields of surgery and forensics.

This study was performed to find out hazardous factors in the loaded works of muscular skeletal disorders(MSDs) for four company attached to dining workers from October 2005 to June 2006. The results are summarized as follows. 1. 42.5% of workers in study group were 40-50 years old, and females were higher than males, and the average of body weight was 70kg, 57kg in males and females, respectively. Working time per day was mostly 7-9hours, and the rate of worker who had never education and training was 46%. 2. The upper part and right part of body were higher than lower part and left part in symptoms of muscular skeletal disorders. Body parts which complained of symptoms were the order of right shoulder(55%), right arm(54%), right hand,(40%) waist(35%), leg(25%), and neck(24%). 3. The results of evaluation in the loaded works of muscular skeletal disorders to cooking, dish supply, preparing side dish, and washing the dishes and cleaning the floor of cooking room using RULA and OWAS checklists was action level 4(potential hazards, needs of change workplace), and the result of evaluation using back compressive force needed control measures as 779.27 lbs~1,274.04 lbs. In a view point of the result of this study, large dining rooms should be designed by ergonomic technology for the work surface height, width, and depth. The height of carrying car should be lower to 70cm, and repetitiveness and handling weight should be reduced by mechanical means, and education and training also should be performed for all of workers positively.

Penetrating chest trauma by stab injury may result in massive hemothorax from damage to single or multiple intrathoracic organs such as heart, aorta, internal mammary artery, intercostal artery or pulmonary parenchyme. Prognosis of massive hemothorax necessitating emergency thoracotomy is fatal especially so if there exists concomitant underlying compromise of cardiopulmonary function. A 56 year old man with destroyed left lung due to old pulmonary tuberculosis was stabbed in right parasternal lesion through third intercostal space. Intubation with cardiopulmonary resuscitation and closed thoracostomy were performed to resuscitate from cardiac asystole from hemorrhagic shock and acute respiratory distress. Midsternotomy was made to expose active bleeding foci in right mammary artery, subclavian vein, intercostal artery and anterior segment of right upper lung showing severe bullous change and pleural adhesion. Postoperative care included ventilator support, inotropic instillation and cautious, balance fluid therapy ; successful extubation was done on third postoperative day and patient was discharged on tenth postoperative day without any complication.
