1950년대부터 많은 개발도상국가들은 가족계획을 위주로 하는 인구제어정책을 추진하여 왔다. 특히 가부장제도를 중심으로하는 동아시아 국가들에 있어서는 남아선호관이 출산력 저하나 피임 실천율이 증대에 지대한 유해요인으로 일관해 왔다. Sheps(1963)는 실증적으로 2명의 아들을 갖기 위해서는 약 3.9명 정도의 자녀를 두어야 한다는 연구결과를 제시한바 있다. 이와 같은 남아선호관의 여파에도 불구하고 한국과 홍콩은 1980년대 증반에 이미 1.6명 수준의 저출산율을 이룩하였으며, 1970년대에 인구억제 정책을 시작한 중국도 2명 수준으로 저하되어 가족계획사업의 성공사례로 평가되어 왔다. 그러나 이들 국가들의 출산율은 지난 20-30년이라는 짧은 기간에 너무나 급진적으로 감소된 반면에 남아선호관의 상존으로 인한 성비(여자 100명당 남자수)의 불균형을 초래하게 되였다. 한 예로 한국의 경우 1960년도만 해도 6명 이상의 자녀를 출산하는 과정에서 1-2명의 아들을 둘 수 있는 확률은 매우 높았으나, 최근에는 출산율이 2명 이하로 저하되어 아들을 둘 수 있는 확률은 과거보다 3-4배 어려워졌기 때문에 인위적인 방법으로 아들을 두는 부모의 수가 증가하고 있다. 중국은 1970년대 중반기부터 강력히 추진되어온 소위 "한자녀 갖기 운동"으로 인하여 여아출산인 경우 영아살해 또는 출생의 미신고등 많은 사회적 물의를 야기하였고, 최근에는 초음파검사를통한 선택적 인공임신중절(태아가 여아인 경우)으 경우가 급격히 증가하고 있다. 우리 나라의 성비는 출산율이 급격히 감소된 1980년대 증반기부터 급격히 증가되었다. 즉 인구전체에 대한 성비는 1980년의 103.9명에서 1985년에 110명으로 증가하였고ㅡ 1990년 116.9명으로 증가되었다. 성비는 자녀의 수가 적을수록 높아지는 추세이다. 1991년 조사에서 출산을 종료한 부인의 경우 1자녀의 성비는 무려 206명이나 되고 있다. 이와 같은 결과는 한자녀를 원하는 부인이 아들을 둔 경우 1자녀에서 조산을 결심하기 때문인 것이다. 통계청 자료에 의하면 성비는 무엇보다도 자녀의 출산순위와 밀접하다. 1991년 출생신고자료의 경우 첫아이의 출생시 성비는 106.1명이고, 둘째아이가 112.8명이나, 셋째아이는 184.7명으로 크게 증가하고 넷째 이상의 경우는 212.3명이나 된다. 동일한 출산순위라도 이미 두고 있는 자녀의 성에 따라서 많은 차이를 보인다. 1991년도 3번째 출산의 경우 딸만 2명을 두고 있는 자녀의 성에 아들만 2명 또는 아들과 딸을 각각 1명씩 두고 있는 경우에 비해 높은 성비를 보이고 있다. 자녀를 출산하는데 있어서 처음에는 아들ㅇ르 기다리지만 딸의 수가 증가함에 따라 적극적으로 아들을 낳고자 하는 노력을 지속하게 됨을 알 수 있다. 이는 즉 임신한 자녀의 성이 딸로 판명되면 인공임신중절을 통해 임신을 종결시키고 있음을 의미한다. 최근 한국보건사회연구원에서 수행한 연구결과에 의하면 이미 출생한 자녀의 성구성은 임신결과를 결정하는 가장 중요한 변수로 부각되고 있다. 즉 임신이 인공임신중절로 귀착되는 확률은 부모가 이미 아들을 두고 있는 경우에 일관성 있게 증가되고 있음을 보이고 있다. 따라서 남아선호관은 임신결과를 결정할뿐 아니라 선택절 인공임신중절에 의한 성비의 불균형을 초래하는 주요 변수로써 할거되었다. 특히 피임실천이 보편화되고 선택적 인공임신중절의 이용이 손쉬운 현대사회에 있어서는 남아선호관이 출산력 저하에 저해요인으로서가 아니라, 인위적이던 자연적이던 간에 아들만 두면 단산하는 현행의 출산풍토하에서는 남아선호관이 오히려 출산력저하에 결정적으로 작용하고 있다고 하겠다. 태아의 성 판별을 통한 선택적 인공임신중절의 건수는 1990년 한해에 약 20,000건 정도가 되고, 1986-1990년 사이에 총 80,000건으로 추정된다. 이 수치는 출생한 여아수의 5%에 해당한다. 현재 출생시 성비의 불균형은 연간 총출생수의 10% 미만에 불과한 3번째 이상의 출산에서 발생되고 있기 때문에 인구학적인 측면에서는 큰 문제가 아니다. 그러나 앞으로 출산율의 감소와 더불어 선택적 인공임신중절이 년간 출생수의 90% 이상을 차지하고 있는 둘째, 첫째출산순위로 확산된다면 성비의 불균형은 급진적으로 가속화되어 전통적 결혼관습의 재연등 인간의 생태계를 파괴하는 새로운 차원에서의 사회인구학적인 문제가 야기될 것이다. 결론적으로 성비의 불균형을 초래하는 근본적인 원인은 우리 나라으 전통적인 의식구조인 남아선호관의 상종과 최신의 의료기술에 의한 선택적 인공임신중절에 기인된 것이기 때문에 이를 시정하기 위한 제반 사회제도적 극복정책은 지속적으로 강화되어야 할 것이다.되어야 할 것이다.

Stage art basically builds upon the essence of "seeing," and at the same time, possesses relativity in showing and seeing. Stage lighting uses artificial light to solve the essence of "seeing", which is the foundation of stage art, and coming into the modern age, its role has been enhanced to an important medium for visual expression in stage art, due to the lighting tools that developed at a rapid pace along with the discovery of electricity, as well as the development of optics. Therefore, not only does lighting use a medium known as light in a field of stage art that gives mental and emotional inspiration to the audience, and aesthetically expresses time and space. In other words, stage lighting is a complex function of light engineering (technology and science) and aesthetic sense (feeling and art). This study aims to do research on methods for the visualization of stage space through lighting, mainly focused on dancing. I have studied the basics of stage lighting, its relations with other fields of stage art, and the functions and characteristics of lighting. Results show that lighting could be used to maximize the visualization of dancing and emphasizing the artistic growth of lighting and its ability to aesthetically express and I came to the following conclusions. First, lighting uses the forms and directions of light that various tools are able to produce in order to visualize the space on stage, and can maximally express the image that the work seeks. Second, it is possible to use lighting, through the movement of light, as a visual representation of the configuration of space in dancing works. Third, through the expression of visual and spatial aspects created by light, the work's dramatic catharsis can bring out mental and emotional feelings form the audience. Fourth, lighting can be seen not as a supporting role, but as an original visual design. To conclude, in order for lighting to be freed form the simple function of "lighting up the stage," which a majority of people think is common knowledge, and grow as one area in art, lighting designers must understand the intentions of the choreographer and the work with creativity and artistry they must consider light and color as an aesthetic language in order to heighten the effects of the work and allow it to partake as one element of work creation, so that lighting will be treated as a form of art.

According to Edwin Gordon(1987, 1997, 2003), music aptitude is a product of interaction of innate potential and early environmental experiences. He referred to music aptitude of children up to nine years of age as developmental music aptitude which fluctuates due to musical environment. Music aptitude stabilizes at age nine, and the music aptitude after age nine is called "stabilized music aptitude". This research is to examine Gorden's hypothesis that the younger a child receives music education, the higher music aptitude. Also, this research is to experiment the effect of Audiation activities developed in Audie Music Curriculum on music aptitude. The researcher and another Audie teacher as a co-teacher guided children together for 30 minutes once a week. The pedagogy guidelines for informal guidance in music learning theory were kept throughout the classes. Also, Audie's teaching method which had been developed for Korean Kindergarten educational environment was also applied. Five-year-old subjects in Experimental group 1 experienced the Audie Music Curriculum of one year; five-year-old subjects in Experimental group 2 experienced it for two years. Primary Measures of Music Audiation was administered three times during their last year of Kindergarten. Subjects in the Control groups, one examined at the beginning and the other at the end of their last year in Kindergarten, received no Audie instruction. There was no significant difference in tonal aptitude, but there was significant difference in rhythmic aptitude(p< .05) among the experiemental groups. Because both Experimental groups showed statistical significance (p< .001) in the music aptitude increase during their academic years, the significant differences of the year-end music aptitude between control group and experimental groups were the expected result.

The purpose of this study was to verify the influence of musical activities on social and emotional behavior of infants, through providing musical activities to the infants who were cared in a nursery and observing the interactions between peer group, or a therapist and an infant derived during them. The subject is 24 infants who are under 2 years of age(25~36months) at two nurseries located in Bundang area, and 13 infants among them are randomly assigned as study group and 11 infants as control group. Pretest and posttest about social and emotional behavior are performed, and ITSEA developed by Brggs-Gowan and Carter(2001) and amended by Shin Ji Yeon(2004) was used as an evaluation tool. Infants' changes of interaction behaviors during musical play were also analyzed quantitatively and qualitatively, and for the analysis, infant's social play behavior examination tool developed by Holloway and Reichhart-Erickson(1988) was adopted. Based on time sampling method, each item of this tool was evaluated. Each session was performed for 15 minutes, and 60 times of analysis about interactions per session was conducted at every 15 seconds. The analysis result was showed with a table and a graph, and described qualitatively about behavior changes. When compared social and emotional positive behavior average figures and negative behavior average figures between study group and control group, this study showed that the positive behavior figure of study group was increased and the negative behavior figure was decreased. While concentration and empathy among positive behaviors increased meaningfully, aggression, defiance, separation anxiety and rejection to new things among negative activities also decreased meaningfully. The conclusion of this study is as follows. First, interactions with peers or a therapist based on music and musical experience make an effect on strengthening positive behavior among social and emotional behavior and decreasing negative behavior. Second, music has influence on negative behaviors more than positive behaviors of an infant, and produces a good effect on sub behaviors of negative behaviors specially.

The purpose of this study is to quantitate regional neurochemical profile of regional normal adult mice brain and assess regional metabolic differences by using ex vivo $^1H$ high-resolution magic angle spinning nuclear magnetic resonance spectroscopy ($^1H$ HR-MAS NMRS). The animals were matched in sex and age. The collected brain tissue included frontal cortex, temporal cortex, thalamus, and hippocampus. Quantitative 1D spectra were acquired on 40 samples with the CPMG pulse sequence (8 kHz spectral window, TR/TE = 5500/2.2 ms, NEX = 128, scan time: 17 min 20 sec). The mass of brain tissue and $D_2O$+TSP solvent were 8~14 mg and 7~13 mg. A total of 16 metabolites were quantified as follow: Acet, NAA, NAAG, tCr, Cr, tCho, Cho, GPC + PC, mIns, Lac, GABA, Glu, Gln, Tau and Ala. As a results, Acet, Cho, NAA, NAAG and mIns were showed significantly different aspects on frontal cortex, hippocampus, temporal cortex and thalamus respectively. The present study demonstrated that absolute metabolite concentrations were significantly different among four brain regions of adult mice. Our finding might be helpful to investigate brain metabolism of neuro-disease in animal model.

It is expected that the typical lifestyle of the future will be transformed into an opulent and comfortable existence as the quality of life improves due to the increase in household income and reduction in working hours. In the meantime, as the standard of living becomes increasingly more comfortable and plentiful, the toll on physical health becomes magnified as a result of obesity and insufficient exercise caused by super nutrition and change in labor conditions (from physical labor to mental labor). This has instigated a deep awareness in fitness on the part of many people, forcing them to recognize the significance of daily exercise and physical activity. The high annual growth rate in the fitness and athletic apparatus market, which is more than 20%, is attributed to this phenomenon. The Elliptical Cross Trainer(ECT), which has drawn wide attention recently, is a non-impact athletic apparatus that not only promotes exercise of the upper body parts in such sports as skiing but also the exercise of lower parts of the body on a treadmill. It is a type of cross training athletic gear that has been developed for aerobic exercise throughout the entire body. It has already formed a market as big as that of the treadmill in Europe, America, etc. Recently, its demand is growing sharply in the Korean markets as well as those in Northeast Asian countries, Despite such demand increase and expansion, since most of the expensive ECTs are exclusively supplied by suppliers in only a few advanced countries, localization of the ECT is urgently required in order to enhance competitiveness of Korean manufacturers and to expand the market. This paper introduces the process and results of a design-engineering cooperative study that was peformed for the development of the ECT.

It is the better to take preventative measures against the natural intrusion in advance from invasive alien species that reduce biodiversity and cause economic loss to humans. If the prevention of intrusion and spread fails, we need to make active control and eradication. This study aims to introduce nutria (Myocastor coypus) control cases performed in the United Kingdom and the United States and to provide information for the contribution of nutria management measure improvements. The nutria eradication campaign in the United Kingdom was developed as a long-term plan based on sufficient understanding on the management target and objective and suitable support. Sufficient information on nutria was accumulated and the management strategy was flexibly modified according to the changes in management that were proactively reflected in the field. Regarding the eradication project at Chesapeake Bay in the United States, based on long-term ecological information, more advanced capture technology than in the United Kingdom were introduced and the eradication plan, strategy and implementation were configured by analyzing the strengths and weaknesses of the eradication campaign in the United Kingdom. The successful cases in the United Kingdom and the United State provide an information on how to improv the nutria management measure. For the eradication of nutria, it is necessary to reach a consensus between stakeholders and to form a consultative group between related organizations for periodic communication. Opinions on the field must be actively accepted in the consultation process for strategy and policy decision, and the eradication plan needs to be developed based on a management index. The eradication plan is required to be managed, evaluated and adjusted in a systematic way. Scientific management must be introduced and the management performance must be evaluated objectively so that a practical plan can be flexibly adjusted. It is also required to secure a long-term budget support and a stable organization and to input a concentrated budget at the proper period when there is high efficiency of eradication.

The purpose of this study was to offer fundamental data to manage countertransference, and to research into countertransference management ability by aspects in therapists' experiences in countertransference and their professional characters. For the paper, a survey was conducted on 62 music therapists who provided professional music therapy after finishing graduate school of music therapy through clinical practice and internship, and the result was drawn as follows. Around 84% of participants answered that they had been in trouble by countertransference in the analysis of a questionnaire regarding experience in countertransference. 48% among them first experienced countertransference during the practice in graduate school. 27% and 14% respectively answered that they experienced it within 3 years after graduation and during internship. Also, the result showed that therapists usually had difficulty with adults with mental disease, and the second most difficult clients were children with developmental disabilities. 76% of participants who had difficulty by countertransference answered that they were able to manage it to some degree, and almost all who answered thought that research into countertransference and management were necessary. About the question as to how to manage countertransference, 54% suggested self-analysis and self-therapy. 33% answered that countertransference should be treated through supervision. Finally, 13% of participants answered that it should be handled in graduate school. In this paper, which empirically examined therapists' experience in countertransference and countertransference management ability had meaning in providing essential basic data for music therapists to apply and manage countertransference for therapists themselves, as well as for clients.

This study was conducted to determine the effects of horticultural therapy (HT) program using hydroponics on work adjustment skills of students with mental retardation. Based on the critical role transitional model and special education curriculum for agriculture, especially hydroponics, HT program (total 22 sessions) using hydroponics procedure for Lettuce (Lactuca sativa L. 'Asia Heuk Romaine') was developed. Fourteen (10 males, 4 females) graded $1^{st}$ to $2^{nd}$ with intellectual disabilities were recruited from a special education class in a high school located in Inchon, Korea and then a special farm for hydroponics in Inchon, Korea was offered for the HT program. The students with intellectual disabilities participated in the HT program for 4-month (from September to December of 2011, twice a week, approximately 60 minutes per session). Before and after the HT program, the McCarron assessment neuromuscular development, emotional behavioral checklist, interpersonal negotiation strategies, and KEPAD picture vocational interest test were performed by the teachers and horticultural therapists. As the results, the students significantly improved motor performance (p = 0.002), emotional behavioral strategies (p = 0.00), and interpersonal negotiation strategies (p = 0.05). However, no significant difference between before and after the HT program for vocational interest was observed. In conclusion, the HT program using hydroponics, consists of simple and easy tasks so that it would be applicable for the students with intellectual disabilities positively affected to work adjustment skills by improving the motor performance, emotional behavioral strategies, and interpersonal negotiation strategies. Additionally, HT programs using hydroponics with various kinds of vegetables are required to develop and to apply in practical settings for improving work adjustment skills.

Unlike other common forms of speech disorder, such as phonological disorder or dysphonia, stuttering has not been studied within the context of music therapy. Most cases of stuttering display no difficulty in singing, and fluency within the musical structure does not translate to fluency in speech. Hence, musical approach has been generally considered to be ineffective to the treatment of stuttering. However, the fundamentals of music therapy assume its extensive application in treating variety of speech disorders, including the case of stuttering. Presented in this paper are the case studies designed to validate the efficacy of music therapy as a remedy for stuttering. This study enrolled 6 children with stuttering and conducted 20 individual sessions over a period of 10 weeks. The sessions focused on the Melodic Intonation Therapy, Reinforcement of speech rhythm, song writing and singing. Musical elements were structured to enhance the verbal expression and rhythmic senses, as well as to facilitate the initiation of verbal communication. The result is as follows. First, it was noticed that the disfluency had been decreased in before and after of the music therapy in every child although the result was somewhat different depending the child. The overall result of the investigation shows the significant difference statistically. And categorically speaking, the significant difference was checked in the frequency of the stuttering. In the steps of the session, the increase and decrease was happened repeatedly, and then after it was decreased little by little. Secondly, the Communication Attitude was decreased in before and after of the music therapy, and also there was significant difference statistically. although the avoidance behavior was decreased in before and after of the music therapy, the increase and the decrease was repeated irregularly in the steps of session. All the results described above shows that music therapy gives positive effect to decrease in disfluency of stuttering child and also to develop the Communication Attitude. And new possibility and effectiveness can be proposed in the musical approach to the stuttering.
