For a lack of books on tea ceremony, 'Dongdasong (東茶頌)' by Buddhist priest Choui occupies a prominent position. Along with 'Dabu (茶賦)' by Yi Mok (李穆: 1471~1498) and 'Gida (記茶)' by Yi Deok-ri (李德履: 1728~ ?), Dongdasong forms the three peaks of tea work. These books are all based on Tea Classic (茶經) by Ryukwoo (陸羽). Assuming that Tea Classic serves as introduction (起), Dabu is development (承), Gida for turn (轉) and Dongdasong for conclusion (結). Dongdasong is inextricable from Dasinjeon (茶神傳). Dasinjeon is the abstract of Jangwon's Darok (茶錄). The keyword of Dasinjeon is 'tea deity (茶神).' Extracting key concepts of Darok as his perspective, Choui established his own philosophy on tea ceremony. In the process of making into his philosophy, he reorganized the system by introducing the principle of 'subtle combination (妙合),' one of traditions in Korean thought, which is characterized by not separating spirit and material. It is 'subtle combination' that does not make a division between spirit and material, which are undeniably different things. Subtle combination is a relation of two things' being one and one thing's being two. Choui's philosophy on tea ceremony can be assessed as valuable inheritance from traditions of Korean thought.

The objective of this study is to kinematically analyze forehand & backhand strokes of abscission handicap wheelchair table tennis athletes. The participant of this study were picked out of national athletes who have abscission handicap. Forehand stroke movement was expected to show a throw like motion. However, external rotation and internal rotation of the right arm created a backswing and an impact. Backhand stroke was expected to show a push like motion, and as expected, proximal part of the body didn't participate in the stroke motion, but the distal part, the right arm, rotated internally to backswing and external rotated to impact to form a push like motion. Forehand swing was expected to show throw like motion according to the Link Segmental System principle. However, abscission handicap athlete didn't show clear linking structure connecting proximal and distal parts. Successful strokes were dependant only on the angle of arm rotation.

이 논문은 Minnesota대학 Paul Campus 도서관 부관장인 존슨(P. Johnson)이 Journal of Academic Libraianship, Vol. 16, No. 4(Sept, 1990), pp.222-229에 게재한 "Matrix Management: An Organizational Alternative for Libraries"을 완역한 것으로, 도서관의 전통적인 조직구조에 대한 대안을 모색하는데 참고할 수 있는 이론적 논문으로 사료됨. 도서관조직구조가 점점 복잡해 짐에 따라 다양한 방안들을 모색하여 왔다. 이 논문은 전통적 계층구조에 대한 대안으로서의 매트릭스구조의 효용에 관하여 논의 한 것이다. 매트릭스관리가 매우 성공적으로 이루어질 경우에는 사서들에게 유연성을 증대시키기 위한 신전략과 고도의 전문적 독립성, 그리고 보다 균형된 의사결정과정을 제공해 준다. 제2차 세계대전까지만 해도 도서관을 포함한 대다수 기관의 조직구조는 몇 가지로 나눌 수 있었다. 비록 이들 조직구조가 바뀌게 되었다 하더라도 그것은 의도적인 계획하에서 진전된 것이 아니라 안정적이고 예측가능한 환경에 매우 적합하도록 자연스럽게 이루어진 것이다. 다만 최근 여러 해 동안 급격한 환경변화로 인하여 보다 새로운 조직구조가 발전하게 되었는데, 이는 자연진화적인 조직변화라기 보다는 오히려 특정적 요구를 충족시키기 위한 자의적인 계획의 결과라고 하겠다. 이와 같은 급격한 변화에 대처하도록 특별히 계획된 매우 혁신적인 조직구조중의 하나가 조직매트릭스이다. 이 논문은 대학도서관에 있어서 조직구조, 조직대안으로서의 매트릭스구조, 매트릭스경영관리의 효용 등 세 가지의 문제에 대하여 고찰하고자 한다.<역자주>

Irreducible knee dislocation is a rare injury and often need an open procedure with ligaments reconstruction. This report describes a case of arthroscopic treatment of a patient with traumatic knee dislocation unable to reduce in a closed method. MRI revealed incarceration of the medial collateral ligament and capsule in the medial compartment. And arthroscopic examination confirmed incarcerated medial capsuloligamentous structures which prevented the knee from reduction. Arthroscopic procedure without ligaments reconstruction was complete when the medial condyle was well visualized and the knee reduced. After 4 weeks of immobilization in extension, range of motion exercise and gradual increases in weight bearing was allowed. At the 3- year follow-up, mild laxity was remained but the patient did not have any discomfort of doing ADL activity and showed full range of motion of the knee.

The purpose of this paper was to make a comparative analysis for the difference of the various kinematic variation which is occurred in the each situation when pitchers throw a straight and a curve ball. Four pitchers, who are two national team players and two high level pitchers, were selected among the right over hand pitchers of D university in the Busan for this paper. The data were analyzed by using 3D equipment. The results of the analysis which was about the elapsed time of the pitching, the movement of the body center-point, the highest height of the left knee, stride length, knee joint angle, shoulder joint angle, elbow joint angle and wrist joint angle in the each section(ST, LKU, HBP, LCF, MCP, BRP) were as follows : 1. Pitching time in the each section and step in the pitching for straight and curve ball was similar. The total elapsed time of the straight and curve ball was 1.78${\pm}$0.07sec and 1.77${\pm}$0.11sec in the order. 2. The position change of the body center to the Z(above below) direction did not show significant difference in the each situation of the section and step between pitching for the straight and curve ball. 3. Height of the left knee did not show significant difference as 125.38${\pm}$11.85cm and 124.95${\pm}$11.63m in the each pitching motion for straight and curve ball. The rate(%H) between height and stride length showed 68.42${\pm}$5.53(%H), 68.40${\pm}$5.45(%H) in the each pitching motion. 4. Pitching for curve ball showed longer stride length than pitching for straight ball that as the stride length was 140.35${\pm}$4.96cm and 144.8${\pm}$1.69cm. The rate(%H) between height and stride length showed 76.9${\pm}$3.77(%H), 79.39${\pm}$2.23(%H) in the each pitching motion. 5. Left knee joint angle did not show significant difference in the ST, LKU and HBP section in the each pitching motion. However, it was shown that knee joint angle was flexed much more in the LFC, MCP and BRP section in the pitching for curve ball. 6. Right shoulder joint angle did not show significant difference in the ST, LKU and HSP section. However, when pitches threw a curve ball in the LKU section. In the LFC section, the right shoulder joint angle was extended much more in the pitching for curve ball, and the angle was extended much in the MCP and BRP section in the pitching for curve ball than straight ball. 7. Right elbow joint angle did not show significant difference in the ST, LKU and HRP section in the two pitching motion. The angle had more flexion in the LFC and MCP section in the pitching for curve ball than the pitching for straight ball. The angle in the each pitching motion for straight ball and curve ball were extended by a narrow margin in the BRP section. 8. Right wrist joint angle was extended much more in the LFC and MCP section in the pitching for curve ball. In the BRP section, the angle was extended much more in the pitching for straight ball than curve ball.

Purpose: The purpose of this study is to analyze the merits and demerits of double bundle reconstruction and achieve improvements hereafter, by comparing the results of double bundle and single bundle reconstruction using tibialis anterior allograft. Materials and Methods: Twenty seven patients were divided to undergo either double bundle(n=14) or single bundle(n=13) reconstruction with tibialis anterior allograft tendon. The evaluation methods were AP laxity with KT-2000 arthrometer, isokinetic knee strength measurements, pivot-shift test, IKDC subjective score, Lysholm knee score, Tegner activity score, radiographic evaluations with postoperative MRI, and second look arthroscopy. Results: Lysholm knee score and Tegner activity score were significantly better in double bundle reconstruction. In pivot-shift test, single bundle reconstruction was evaluated as grade 0 in 10 of the knees, grade 1 in 1, and grade 2 in 2. Double bundle reconstruction was evaluated as grade 0 in 13, and grade 2 in 1. In second look arthroscopy, single bundle was evaluated as excellent in 6 of the knees, fair in 7, anteromedial bundle of double bundle reconstruction was excellent in 13 and fair in 1, and posterolateral bundle was excellent in 4, fair in 9, and poor in 1. There were no significant differences in other evaluations. Conclusion: Favorable outcome may be expected with double bundle reconstruction of ACL. However there are still need for improvement in terms of reconstruction technique and rehabilitation protocol to reduce PL bundle injury.

The current study was performed to investigate the magnitude of exercise-induced muscle damage (EIMD) after downhill running (DR) of different intensities and to examine the availability of muscle echo intensity as biomarkers to detect regional damage within quadriceps muscle group (QG) following DR. Healthy college-age men (n=11) were experienced twice DR sessions [$50%HR_{max}$ DR, LDR; $70%HR_{max}$ DR, HDR] separated by a 2-week wash-out period with the random order. After DR, severity of EIMD according to exercise intensity were determined by serum creatine kinase (CK) activity, muscle tenderness, and neuromuscular function indicators such as a maximal voluntary isometric contraction (MVIC) and range of motion (ROM). Transvaginal B-mode imaging had been employed to evaluate regional muscle echo intensity within QG [rectus femoris, RF; vastus lateralis, VL; vastus medialis, VM; vastus intermedius, VI]. After both DR sessions, changes in serum CK activity and muscle tenderness have tended to more increase in HDR compared to those of LDR. There was a significant interaction effect between exercise intensity during DR and the time course of serum CK activity(p<.05). However, there were no statistical differences between sessions in muscle tenderness. The time course of changes in the neuromuscular functions after DR were similar to those of regional muscle echo intensity regardless exercise intensity. Although neuromuscular function showed to decline in HDR more than those of LDR after DR, no statistical differences between sessions. In contrast, there were significant interaction effects between sessions and time course of changes in RF and VL muscle echo intensity(p<.01), but not shown in those of VI and VM. These results indicated that each muscles within the QG show different response profiles for EIMD during DR, exercise intensity influences on these responses as well. In particular, current findings suggested that muscle echo intensity derived from ultrasound imaging is capable of detecting regional muscle damage in QG following DR.
