본 연구는 골프장 제공서비스와 재구매의도 분석을 규명하기 위하여 연구의 대상자는 D광역시에 소재하는 골프장 및 골프연습장에서 골프회원 활동에 참가하는 20대 이상의 성인 남ㆍ녀 총 364부를 SPSS 17.0 & AMOS 7을 이용하여 자료 분석의 목적에 따라 전사적 통계처리를 분석하였다. 이와 같은 연구방법 및 절차를 통하여 다음과 같은 결론을 도출하였다. 첫째, 일반적특성에서 성별과 핸디에 따라 코스 관리, 물리적 환경, 혼잡지각, 인적서비스, 운영서비스, 재구매의도에서 통계적으로 유의한 차이를 나타내지 못하였다. 구력은 물리적 환경에서 3년 미만의 응답자들이 다른 구력에 비해 물리적 환경 만족도가 높은 것으로 나타났다. 둘째, 인과관계를 보면 내적 환경만족은 외적 환경만족과 재구매의도에 매우 높은 영향을 미치는 것으로 나타났다. 결과적으로 내적 환경만족의 구성요인은 인적 서비스와 운영서비스로 골프장을 운영하는 실무 직원들의 역할이 매우 중요한 것으로 나타났다. 따라서 재구매의도를 강화하기 위해서는 제공서비스에 대한 교육과 관리가 매우 중요하다는 것으로 알 수 있다. 일반 대중들의 소득의 향상과 골프와 관련된 각종 규제의 완화 덕분에 골프는 더 이상 일부 계층의 사람들만이 즐기는 운동이 아니라 대중적인 운동으로 확대되어가고 있다. 하지만 이런 저변의 확대에도 불구하고 아직 정확하게 골프장 만족도의 향상을 위한 연구는 많이 부족한 실정이다. 이에 본 연구는 골프를 즐기는 재구매의도를 강화하기 위해서는 제공서비스에 대한 교육과 관리 및 프로그램개발이 필요함으로 앞으로 좀 더 많은 연구가 진행되어야 할 것이다. This study investigates the influences of service repurchase intention and satisfaction on the inner outer environment satisfaction after participation of customers in golf course. The subjects of this research were the customers who used golf course in D region on 2011. They were less than 20 or more than 50 years old. The survey was conducted with 364 participants by means of the purposive sampling. Based on the colleted data, this survey were analyzed Cronbach"s Alpha, T-test, factor analysis, correlation analysis, structural equation and ANOVA by using SPSS 17.0 and AMOS 7. The result of this study was summarized as follows: first, The result from analysis reveals that sex, handy and career was not related with a service charge or repurchase intention , but the satisfaction of system service on a physical environment had influences in order on customer"s career. Second, the satisfaction of inner environment had important impacts on outer environment and customer"s repurchase intention . this paper I showed one line of research focused on the point of human service and management service as inner environment. This study also requires further studies and this study will be supplemented.

가교폴리에틸렌은 우수한 기계적, 전기적 특성으로 송배전용 케이블 절연재료로 광범위하게 사용되고 있다. 하지만, 망상구조의 가교폴리에틸렌은 재활용을 위하여 화학적인 분해 또는 물리적인 분쇄 과정이 필요하다. 본 연구에서는 탈가교 공정을 통해 제조된 재생 폴리에틸렌에 대한 기계적, 열적, 그리고 전기적 특성을 평가하였다.

The purposes of this research are to compare and analyze muscle activity between Yeopchagi posture of two-feet seogi and Yeopchagi movement of Hakdari seogi posture among the Taekwondo Poomsae and obtain muscle activity data of two. They are to provide scientific basic data by finding movement organization factors, characteristics and similarities and differences of each seogi posture Yeopchagi. Also, to suggest effective direction of performance for guide’s correct guidance and Poomsae player’s Yeopchagi technological movement and contribute to the improvement of Poomsae player’s athletic performance. Research subjects were 7 male Poomsae players who were registered in Korea Taekwondo Association as Poomsae players with award winning careers. The experiment was conducted by wireless EMG T. he conclusions are as follows. First, on the first condition, straight muscle of thigh commonly showed the highest muscle activity in Yeopchagi of two-feet stance posture and Yeopchagi of Hakdari seogi posture. Right straight muscle of thigh in both Yeopchagi of two stance postures showed the highest muscle activity. The second highest muscle activity was straight muscle of thigh in Yepchagi of two-feet stance posture(L) and anterior tibial muscle in Yeopchagi of Hakdari seogi posture(L). And, if examining the characteristics of sequential muscle activity after the second muscle activity of Yeopchagi of two stand postures, Yeopchagi of two-feet stance posture showed the highest muscle activity in support foot and nextly, in muscles of kicking feet. Yeopchagi of Hakdari seogi posture showed the highest muscle activity in kicking foot and nextly, in muscles of support foot. Right gastrocnemius of Yeopchagi of two stance postures showed significantly statistical differences. Second, the muscle which showed the highest muscle activity in Yeopchagi of two-feet stance posture and Yeopchagi of Hakdari seogi posture on the second condition showed the same result as of the first condition. The second highest muscle activity was shown in straight muscle of thigh and there were positional differences as Yeopchagi of two-feet stance posture was left straight muscle of thigh and Yeopchagi of Hakdari seogi posture was right one. So, there were significantly statistical differences in right bicephalus femoris(p<.05) and right gastrocnemius(p<.001). Third, the muscle which showed the highest muscle activity in Yeopchagi of two-feet stance posture and Yeopchagi of Hakdari seogi posture on the third condition was support foot; left straight muscle of thigh in Yeopchagi of two-feet stance posture and right kicking foot in Yeopchagi of Hakdari seogi posture. During the Yeopchagi of Hakdari seogi posture, muscle activity of right straight muscle of thigh was higher than left straight muscle of thigh in the first condition and to the third condition. During the Yeopchagi of two-feet stance posture, right straight muscle of thigh on the first condition and left straight muscle of thigh of the second condition and the third condition showed differences of muscle activity.
