With the economic growth and enhancement of people's consciousness in Korea children's attendance rate of the kindergarten has dramatically increased. Accordingly programs of the kindergarten have been developed variously. Of other programs, music programs are the most important in their role as well as influence on children's emotional development. But the survey on the present situations of kindergarten music teachers shows that teachers' musical ability and tastes dictate children's emotional development. The problems found from the survey are as follows 1. Most kindergartens are equipped with musical instruments but they are not fully utilized or sometimes merely displayed. 2. Many teachers generally don't understand musical talents of each child and they lack techniques in teaching music. These problems are mainly derived from teachers inability to utilze musical instruments and childen's musical talents as well. Now I'd like to suggest a few techniques to teach music effectively, hoping for more enthusiastic and dynamic movement to enhance children's musical ability in future. 1. To understand music, teachers should appreciate classical music through FM broadcast or records or at concerts so that they can form a habit of singing enjoying music. 2. They should practice playing the piano, which is indispensible for music education at kindergartens. Unless they are good at it, they'll lose confidence in music. 3. They should teach music in various ways : unison, duet, troll, rhythmic song, appreciation of music, concert, etc. 4. They should select music very appropriately according to season and children's taste. 5. They should develop children's ability to appreciate music creatively and to build up rhythmical sense. Children have various musical tastes which can be channeled into creative musical minds with vivacious rhythms only when teachers awaken them. Teachers should be aware of these situations and exert themselves to teach children music more effectively. Then the children's world will be filled with emotional euphoria, which in turn will make society joyous and bright.

The results of these are as follow: 1. Half of the students don't have the experience of piano playing at the beginning of their college life. 2. The number of the instrument (piano) in school is not enough for the students. 3. Quite number of the students have their own piano at home. 4. 30 minutes to one hour can be shared for each student to practicing at school is very common. 5. Piano practicing and its playing selections are mainly Czerny 30. 6. Most of the students have their lesson of keyboard instrument once a week. 7. Students take their lesson for 3 or 5 minutes at a time. 8. Students think that the level of keyboard instrument is not bad. 9. Students can play the children's song when they excercise for a while. 10. The difference of the technic of playing piano between the school year is very reasonable but students in Seoul is much superior than in Kyunggi.

It has been about one hundred year since the classical music in western style was introduced to Korea. It seems at first sight to be a little long terms but actually that it is very short period in comparison of the history of classical-oriented birth to reach more than one thousand year. However, the western music in Korea now achieved remarkable developments in some fields such as symphony orchestra, many opera works and advanced educatioin of music theory as well as worldwide player and composer. Above of all, a chorus is familiar and popular form in Korea that anyone may participate in singing together into one voice having enjoyable feeling without any special training. I believe this result also gets from many devoted leaders or conductors for choral coordination as most masters play leading roles in making high-ranking chorus with his special technique. Though active progress in a lot of chorus groups and choirs in church is currently made, the master trained thoroughly is so short at the present state in Korea. Through this treaties, I intended to pay your attention to this subject on the pending issue of education and breeding of a good master for well-arranged chorus, and three main ideas relevant to this subject are as follows: 1. For students of the music department in university, conduct theory have to be switched optional-subject with required-subject so that all of them are able to be a capable choir conductor after their graduation. 2. It is necessary to have an institute or a special opportunity who need to have more training to get a high conducting technique. 3. It is hopeful that music college in university need to put a choir conducting department to bring up the competent choir conductor.

The number of people related to choir is on the increase day by day. The reason is that not only professional musicians but also any one who has interests and talents in choir can easily enjoy it in an emotive atmosphere. The reality of Korean chorus has reached to such a point as requires high techniques of performance. For better performances are there many areas to be studied; Vocalization, Pronunciation, Balance, Blanding, Dynamics, Performing manner and Translation, to name a few. The paper centered on, among other things, posture, breathing, consonance, and pronunciation which are closely linked with voice, the most important thing in choral performances. Sound is vital not merely to choral but to all kinds of music. Thus it is necessary to build up a well-training based on scientific methods. All members of a choir should try to make a united tone which their conductor wants. It is necessary to have a good command of posture, abdominal breath, consonance and definite and harmonized pronunciation of vowels and consonants for better musical vocalization. There are many choruses in Korea but most of them endeavour only with enthusiasm without any musical techniques. Poor performances will continue if some one conducts a chorus only with some experiences and enthusiasm. Therefore a correct knowledge on vocalization and incessant efforts are required for an improved performance. When a conductor recognized the fundamental principles of vocalization, he can possibly have an effective choral performance. It is difficult to expect a perfect performance but the future will be bright when muscians make every effort to develop a beautiful and systematized performances with a welltrained and beautiful voice.

Purpose: This study was conducted in order to compare the ability to control postural sway during perturbation when stroke patients received postural sway induced by head rotation. Methods: This study included 15 stroke patients and 15 healthy adults. Each group was measured by 3D motion analysis for determination of the angle of the neck in static position and by balance performance monitor for estimation of swaying angle in both neutral posture and head rotation position. These results were then analyzed in order to compare the healthy control group and the stroke patients group. Results: In both static posture ($60.7{\pm}4.81$) and dynamic posture ($51.46{\pm}6.87$, $70.8{\pm}6.55$), significant decreases were observed in the angle of head rotation of the patient group, compared to the healthy group (p<0.05), and significant decreases were observed in the sway angle of the patient group when in the neutral position ($3.62{\pm}7$, $24{\pm}0.60$) and head rotation ($3.04{\pm}0.80$, $51.46{\pm}6.87$), compared to the healthy group (p<0.05). Conclusion: According to these findings, patients with stroke tend to restrict the ROM of head rotation and swaying angle in dynamic posture and maintain their posture instability using limitation of head movement relative to the trunk and sway angle of area which is larger than that of affected side in unaffected side.

이관섭,최한성,이재홍 대한물리치료학회 2015 대한물리치료학회지 Vol.27 No.6

Purpose: This study aimed to evaluate changes in the balance ability of patients whose head positions were altered due to stroke. Subjects were divided into three groups to determine the effects of the training on dynamic balance and gait. Methods: Forty-two stroke patients were enrolled. The Visual Feedback Training (VFT) group performed four sets of exercises per training session using a Sensoneck device, while the Active Range of Motion (ART) group performed eight sets per training session after receiving education from an experienced therapist. The Visual Feedback with Active Range of Motion (VAT) group performed four sets of active range of motion and two sets of visual-feedback training per session using a Sensoneck device. The training sessions were conducted three days a week for eight weeks. Results: The comparison of changes in dynamic balance ability showed that a significant difference in the total distance of the body center was found in the VFT group (p<0.05) and Significant differences were found according to the training period (p<0.05). The comparison of the 10 m walk test showed that the main effect test, treatment period and interactions between group had statistically significant differences between the three groups (p<0.05). Conclusion: Head-adjustment training using visual feedback can improve the balance ability and gait of stroke patients. These results show that coordination training between the eyes and head with visual feedback exercises can be used as a treatment approach to affect postural control through various activities involving the central nervous system.

초고속 통신망의 일반화와 다양한 온라인 서비스의 출현으로 인터넷을 통한 대용량 콘텐츠 배포에 대한 수요가 증가하고 있다. 이에 따라 서버와 네트워크의 부담이 커지자 P2P 네트워크 기반으로의 전환 움직임이 활발해지고 있다. P2P 스워밍 기법은 서버의 역할을 최소화하고, 트래픽을 고르게 분산시켜 네트워크 과부하로 인한 각종 문제들을 해결할 수 있으며, 자원의 유지보수 비용 또한 절감시킬 수 있다. 하지만 P2P 스워밍 기법의 특성상 보안 서비스제공을 위해선 많은 메시지 교환이 필요하다. 본 논문에서는 P2P 스워밍기법에서 기밀성, 인증, 무결성, 접근 제어 등의 보안 서비스를 제공하는 효율적인 보안 프로토콜을 제안한다. 제안된 프로토콜은 안드로이드 스마트폰 플랫폼에서 구현하여 실험을 하였다. 제안된 프로토콜은 스워밍기법을 이용하는 상용시스템에 사용될 수 있을 것으로 기대된다. With fast deployment of high-speed networks and various online services, the demand for massive content distribution is also growing fast. An approach that is increasingly visible in communication research community and in industry domain is peer-to-peer (P2P) networks. The P2P swarming technique enables a content distribution system to achieve higher throughput, avoid server or network overload, and be more resilient to failure and traffic fluctuation. Moreover, as a P2P-based architecture pushed the computing and bandwidth cost toward the network edge, it allows scalability to support a large number of subscribers on a global scale, while imposing little demand for equipment on the content providers. However, the P2P swarming burdens message exchange overheads on the system. In this paper, we propose a new protocol which provides confidentiality, authentication, integrity, and access control to P2P swarming. We implemented a prototype of our protocol on Android smart phone platform. We believe our approach can be straightforwardly adapted to existing commercial P2P content distribution systems with modest modifications to current implementations.
