It is necessary to improve mechanical and optical properties in the optical disk substrates as the information storage devices with high storage density using blue laser are being developed. Injection compression molding is regarded as the most suitable process to manufacture optical disk substrates for quality recording and read-out. In the present research, the effects of mold temperature and the insulation layer thickness on gapwise birefringence and the land-groove pattern were investigated. It was found that the values of the birefringence distribution were very sensitive to mold temperature history, and the level of birefringence reduced and, furthermore, the quality of replication was improved due to the insulation layer.

There were reliable or high correlationship between energy and hight, energy and weight as the carolic intake increased but there were no correlationships between energy and endurance power, energy and balance and energy and vertical jump. The conculsions above were based on gymnast's the 10 day carolie intakes when exercising and the 5 day carolie intakes when participating in games.

주류산업(酒類産業)에 대한 정부규제(政府規制)의 문제점(問題點)과 개선방향(改善方向)

강신일,Gang, Sin-Il 한국개발연구원 1988 韓國 開發 硏究 Vol.10 No.3

현재 우리나라 주류산업(酒類産業)이 안고 있는 문제점(問題點)들은 과다(過多)한 정부규제(政府規制)와 대기업(大企業)의 시장지배현상(市場支配現象)으로 요약될 수 있다. 원료배분(原料配分), 가격규제(價格規制), 제조(製造) 및 판매면허(販賣免許), 지역판매(地域販賣) 등 기업활동(企業活動)의 거의 전분야(全分野)에 걸쳐 각종 규제(規制)가 엄격히 적용되고 있어 자유로운 기업활동(企業活動)을 저해(沮害)하는 장애요인(障碍要因)이 되고 있다. 주류산업(酒類産業)에 대한 또 하나의 문제점(問題點)으로서 대기업(大企業)의 시장지배현상(市場支配現象)은 특히 유통업(流通業)에 대한 대제조사(大製造社)의 거래관행(去來慣行)에서 두드러지게 나타나는바 이는 기본적으로 유통업(流通業)의 규모(規模)가 영세(零細)한 데 기인하는 것으로 판단되며 덤핑행위(行爲) 등 유통질서문란(流通秩序紊亂)의 원인이 되고 있다. 본고(本稿)는 이와 같은 주류제조업(酒類製造業)과 유통업(流通業)의 구조적(構造的) 문제점(問題點)을 동시적(同詩的)으로 고찰(考察)하여 제도적(制度的)인 측면(側面)에서의 해결방안을 모색(摸索)하는 것을 그 목적(目的)으로 하고 있다. 본고(本稿)에서 제시하는 주류산업정책(酒類産業政策)의 개선방향(改善方向)을 요약하면 우선 시의(時宜)에 비추어 불필요(不必要)하거나 과도(過度)한 정부규제(政府規制)를 과감히 완화(緩和)하여 기업들이 장기적(長期的)으로 볼 때 소비자선택(消費者選擇)에 의한 상품경쟁(商品競爭)을 통해 환경변화에 자율적(自律的)으로 적용할 수 있도록 하는 것이 바람직하며 현행(現行)의 세제(稅制)에 대해서도 용기개발 및 재고처리 등에 상존하는 불합리한 세제(稅制) 및 주류별(酒類別) 세율(稅率)을 개선하여 여건변화에 따라 탄력적(彈力的)으로 적용(適用)하는 것이 세수위주(稅收爲主)의 조세행정(租稅行政)을 지양하고 주류산업(酒類産業)의 효율성증진(效率性增進)에 도움이 될 것으로 판단된다.

The aim of this paper is to take preventive measures against physical handicaps; to make the reasonable performance in actual fighting; to lengthen a gymnast's life. This paper is prepared for the 86' Seoul Asian Game and for the 88'Olympic Game. Although it is not quite sufficient, I think it will be much helpful for the young gymnasts of 11-17 ages. The results can be summerized as follows: 1) Female gymnasts need the more developed Back Double Sommersault in Floor Exercise, while male gymnasts need the more security in Bach Double Sommersalut Dimount on Horizoneal Bar. 2) In order to make gymnasts maintain their high-grade skills and their life be lengthened and to protect against their unexpected accidents, it is necessary for teachers to be careful of the following skills: a) Back Hand Spring and Back Double Sommersault in Floor Exercise. b) Back Double Sommersault Dismount on Horizontal Bar. c) Back Sommersault Hand Stand on Parrallel Bar. d) Skahara in Long Horse. And in case of female gymnasts, teachers must take care of the followings: a) Triple Twist (720 degrees) in Floor Exercise. b) Back Hand Spring on Balance Beam. c) Back Sommersault Jumping High Bar Hold on Parallel Bar. d) Skahara in Long Horse. 3) Gymnasts should control the rate of operation on Ankle Joint and knee, and they must avoid excessive exercises. Also cooperation is expected of teachers. 4) Gymnasts should take care of themselves in April mostly marked by an external wound; and early cure of it needs positive ecconomic support. The above is made of 210 gymnasts(male 90 gymnasts, whose average age is 13.1 and 120 female gymnasts, whose average age is 12.8); and it is focussed on the ages preparable for the 86' Seoul Asian Game and for the 88' Seoul Olympic Game.
