The purpose of this study was to investigate the effect of forest exercise on blood pressure, heart rate, MDA, and SOD. Twelve volunteers were placed in 2 groups: Forest Exercise Group (FEG, n=6; $age=44.2{\pm}2.68$) and Indoor Exercise Group (IEG, n=6; $age=45.6{\pm}2.97$). The subjects who joined this investigation were asked to participate in forest exercise and/or indoor exercise. Blood pressure, heart rate, MDA, and SOD were collected at rest, just after the submaximal exercise, and 30 minutes after each exercise. For data analysis, mean and standard deviation scores were calculated, and ANCOVA were used. The results were as followings : 1) There was no difference between FEG and IEG on systolic blood pressure after submaximal exercise and at 30 minutes after each exercise., however FEG showed better stability than IEG on diastolic blood pressure at 30 minutes after forest exercise. 2) Both groups showed similar change of heart rate and MDA after submaximal exercise and at 30 minutes after each exercise. 3) Both groups similarly activated on the SOD level after submaximal exercise. However, compared to IEG, FEG showed significant decrease on SOD level at 30 minutes after forest exercise. Therefore, this study suggests that forest exercise may have good effects on blood pressure and MDA, and cardiovascular disease prevention.

The purpose of this study was to analyze sports injuries in athletes with disabilities during the 2015 National Games in Korea. We conducted a survey to assess sport injuries in 171 male athletes with disabilities who participated in this study. The shoulder was most frequently injured, followed by the fingers and low back. Contusions were the most common type of injury, and were usually caused by collisions with teammates or contact with equipment. Injuries often occur during enthusiastic play in both competition and practice sessions. Injured athletes are emergently treated with medicated spray and patch application by the head coach. Warm-up and cool-down exercises are recommended to prevent injury, and physical therapy is effective after an injury occurs. Based on these findings, an injury prevention training program and athletic trainers should be provided for athletes with disabilities to ensure appropriate care and rehabilitation.

Human-powered self-generating devices have been attractive with its operation characteristic independent from outer environment such as weather condition and wind speed. However, conventional self-generators have low electric power output due to their weakly-coupled electromagnetic structure. More importantly, rotary crank motion which is usually adopted by conventional self-generator to generate electricity requires specific skeletal muscles to maintain large torque circular motion and consequently, causes fatigue on those muscles before it can generate enough amount of electricity for any practical application. Without improvement in electric power output and usability, the human-powered self-generator could not be used in everyday life. This study aims to develop a human-powered self-generator which realized a strong electromagnetic coupling in a closed-loop tubular structure (hula-hoop shape) for easy and steady long-term driving as well as larger electric output. The performance and usability of the developed human-powered generator is verified through experimental comparison with a commercial one. Additionally, human workload which is a key element of a human-powered generator but not often considered elsewhere, is estimated based on metabolic energy expenditure measured respiratory gas analyzer. Further study will focus on output and portability enhancement, which can contribute to the continuous power supply of mobile equipments.

The aim of this study is to analyze the process of the struggle and bargaining for the change of the employment position of the irregular (in-house subcontracted) workers being at work in the Hyundai Motor Company (HMC) plants into the status of the regular employee of the company, and evaluate the results and limitation of the irregular workers' movement. Since the unionization of irregular workers in 2003, they have carried on the struggle against and the bargaining with the HMC, over the past 10 years and more, making claims for abolishing 'illegal temporary agency work' and for converting their positions into the regular ones. The HMC have gradually altered a confrontational stance against the workers' claim at the early stage, into the bargaining relationship with irregular workers' union. Eventually, the collective agreement on the 'special hiring' of about six thousands irregular workers by the HMC was reached in 2016. We attempt to analyze in depth the overall process by dividing three phases of the movement, according to the criteria of the relationship between the alliance and conflict system, and the cycle of protests of irregular workers. Furthermore, we try to trace the long and winding path of the movement, focusing on the cooperation/conflict relationship within the movement's alliance system, the confrontation/bargaining relationship between the movement and the conflict system, and the critical roles played by mediators (or third parties) between two systems. In the conclusion of the paper, we evaluate the results and limitation of the irregular workers' movement upon the basis of the following points; the convergence of the workers' demands into the prime goal of 'becoming HMC's regular employee,' the breakaway of regular workers' union from the movement's alliance system, and a virtual extinction of irregular workers' union after the final labor-management agreement of 2016.

This study is to analyze and interpretate strategies and managing behaviors in order to propel village mini-library movement in Korea from the starting year of the village mini-library to 1980. The strategies conducted for propelling the movement can be divided into two: one is the strategies, as an output goal, related to establishing and managing mini-library; the other the strategies, as a support goal, related to carrying out the movement procedures. Therefore, the study is to examine the two strategies individually using by the qualitative research method such as analyzing related historical records and literatures, interviewing the persons concerned. and organizing the author’s experience.

The people who is returning to the community after hospital treatment are faced with the choosing where to proceed with rehabilitation exercise with an appropriate exercise specialists based on the current health condition of them. It is required to supprot a personalized exercise rehabilitation service (hereinafter referred to as ARES system) in the community based on individual disease information and health conditions based on hospital clinical data. In this study, we designed a resource management system for online-to-offline (O2O) based coach matching to improve accessibility with facilities and coaches for exercise rehabilitation in the community.

자가혈당측정은 당뇨병 관리에 있어 나침판과 지도와 같은 역할을 합니다. 이는 혈당수치를 보면서 고혈당과 저혈당을 확인하여 즉각적으로 대처할 수 있고, 식사요법, 운동요법, 스트레스 등이 혈당에 어떤 영향을 주는지도 확인할 수 있어 생활습관을 개선하는데 도움이 되기 때문입니다. 또한 인슐린주사를 하는 경우에는 혈당치를 확인하여 인슐린 용량을 조절할 수 있기 때문입니다. 이렇듯 자가혈당측정을 하는 것이 당뇨병관리에 있어 많은 도움이 되어도 혈당검사를 소홀히 하는 경우를 볼 수 있습니다. 이에 금번 호에서는 자가혈당 측정에 대한 당뇨병환자의 마음상태와 혈당에 대한 "감(Sense)을 파악하는 법과 혈당조절을 위한 행동요령에 대하여 소개합니다.

시설을 설치하고 운영하기 위해서는 이 시설을 사용할 대상에 대하여 고려하여야 한다. 교통 시설을 이용할 주요대상은 인간과 차량이기 때문에 이들에 대한 특성분석은 교통공학의 연구분야에서 기초지식이 된다. 교통운영은 물론 교통시설의 설계와 설치에 관련하여 차량의 물리적인 특성과 한계, 사람 특히 운전자와 보행자에 대한 행태 분석은 시설 사용시의 소통측면과 안전측면에서 볼 때 필수적으로 연구되어야 할 과제이다. 본 장에서 다루는 주요과제는 차량의 특성 중 정태적인 특성과 운동에 관한 기초이론, 운전자의 행태 및 보행자의 행태에 관한 일반적인 특성이다.
