Scoliosis can be biomechanically described as a three dimensional deformity of the spine, with deviations from the physiologic curves in the sagittal and frontal planes, usually combined with intervertebral rotation. Various factors are suspected such as genetic defects, uneven growth of the vertebrae, hormonal effects, abnormal muscular activity, postural problems, or a mix of some of these elements, but its initial cause is known in only 15-20% cases. The screening test for diagnosing scoliosis is called the Adams Forward Bend Test. During the experiment, the subjects were asked to bend over, with arms dangling, until a curve could be observed. The Scoliometer was placed on the back of the subjects and used to measure the difference between the left and right apex of the curve in the thoracic, thoracolumbar and lumbar area. Then, the subjects were asked to perform Maximum Voluntary Contractions (MVCs) using the digital back muscle dynamometer in three different postures: (1) 0o (sagittally symmetric); (2) 30o from the mid-sagittal plane (clockwise); and (3) 30o from the mid-sagittal plane (counterclockwise). In addition to the experimental data, subject-dependent variables including Body Mass Index (BMI), percentage of body fat and muscle mass of left/right arms and legs were employed to reveal the cause of difference among three MVC conditions. All those variables were tested using statistical methods.

The study aims at exploring a general trend of psychological well-being (PWB) of elderly volunteers and analyzing the variables which give effects on their PWB. The subjects were two hundred men and women over 60 years old currently participating in voluntary service. The data collected from interviewing were analyzed by descriptive statistics, $x^2$ test, Pearson's correlation and hierarchical multiple regression. The main results are: First, PWB of the elderly is higher than the average score of PWB. Second, the elderly's generativity is positively related to PWB. Family support such as an emotional and instrumental support was also positively related to PWB. Third, the variables effecting on PWB of elderly volunteers were education level, participation frequency, generativity level, and an instrumental support of their family members on it. The lower their educational level was, the more frequently they participated in voluntary activity, the higher their generativity level was, and the more support given from their family, the higher PWB scores they showed.

Purpose: Since 2010, many universities in Korea have been implementing Green Leader Training Programs which are usually run by students themselves. In the last five years of 2015, the Green Leader Training Program under the sponsorship of Korean Association for Green Campus Initiative has promoted the practice of a green campus and many relative projects have been carried out in various fields. Method: We utilized the green campus component index established by the Presidential Committee on Green Growth in Korea and have analyzed 480 activities during the years of 2010~2015. Result: We found that many activities were classified into the environmental field(264, 55.0%). This was followed by university members' participation(130, 27.1%), community engagement(68, 14.2%), and university management(18, 3.7%). These results showed that the green campus initiatives were focused on the environmental field. The number of universities participating from 2010 to 2015 were 20 in the metropolitan area and 15 in the non-metropolitan are. In the metropolitan area, 81.7% of green leader activities were conducted at universities in Seoul, and those in non-capital areas were active in the Middle region(51.3%) and Yeongnam region(48.7%). On the other hand, there was no activity in the Honam region, and it shows that there was a noticeable differential by regional groups.

The basal ganglia are a group of nuclei located in the deep portion of the brain. Along with the cerebellum, the basal ganglia have a major role in controlling human voluntary movements, and their dysfunction is apparently responsible for various involuntary movements. Although the exact mechanism of how the basal ganglia control movements has yet to be clarified, the model of focused selection (through the direct pathway) and tonic inhibition (via the indirect pathway) is proposed to be a principal functional model of the basal ganglia. Parkinson's disease (PD) is classically characterized by bradykinesia, rigidity and tremor-at-rest. All features seem to be associated with dopamine depletion resulting from the degeneration of the nigrostriatal pathway, which produces reduced activity of the direct pathway and a concurrent enhancement of excitatory output from STN. This change may result in increased tonic background inhibition and reduced focused selection via the direct pathway, causing difficulties in performing voluntary movements selectively. However, it has not been possible to define a single underlying pathophysiologic mechanism that explains all parkinsonian symptoms. Here the data that give separate understanding to each of the three classic features are discussed.

This study examines how economic preparation for later life directly influences life after retirement. As people's life cycle is gradually getting longer, preparation for the later time with less economic activity after retirement is becoming more important. Thus, this study analyzes the factors influencing life after retirement. Data comes from the Korean Retirement and Income Study (KReIS) surveyed carried out by the National Pension Research Institute in 2015. The analysis includes Cronbach's alpha, Pearson Product Moment Correlation Coefficient and Sobel Test. This study confirms that voluntary retirement has a positive influence on life satisfaction. Results are in line with previous research about the relationship between voluntary retirement and retired life. When a person retires voluntarily, financial preparation can be made in advance for retirement. In case of involuntary retirement, people may experience a sense of loss in personal standing and financial difficulties due to the unexpected situation. Especially, early retirement from the main workplace leads to unstable later life. The study's policy recommendation, in particular, calls on government and businesses to agree on social responsibility for helping employees to retire in the predictable retirement time and, thus, enabling the retiree to decide all aspects of the path after retirement.

The amount of energy consumption in the buildings is approximately 20% of domestic energy consumption. The Carbon Point Program have been published on reduction of greenhouse gas emission in buildings under the paradigm of 'Low Carbon Green Growth'. This study focuses on the effect of 'Carbon Point Program' for residential buildings in Daegu. The amount of electricity and waterwork consumption and information of households were investigated to analyse the effect of carbon point program. The samples are situated in Deagu and are apartment in Bukgu and Suseonggu. The $CO_2$ emission is analysed by factors of energy resource and household organization between before participating and after participating in Carbon Point Program. The participation type has a difference of voluntary participation in Suseonggu and passive participation in Bukgu. Based on this investigation, average amount of $CO_2$ emission was reduced from voluntary participation households but all of them did not. To promote the effect of Carbon Point Program, this study proposes that needing the plans to raise will and activity of reducing carbon and to help participation which have disadvantage against achieving reduction.
