Purpose: This study was designed to compare the accommodative amplitude whose 40s initial presbyopia patients divided into five occupation (driver, official worker, housewife, field worker, teacher). Methods: Both "push-up" and "minus lens to blur technique" methods were used to examine the average of accommodative amplitude. Results: All the average of accommodative amplitude (OD, OS, and OU) were the lowest in official worker group (3.27.21D, 3.31.22D, 3.54.28D) and the highest in housewife group (4.07.35D, 4.11.35D, 4.37.39D). Conclusions: Because occupational specifications including a fixative habit are able to change the binocular accommodation, it is important to understand thoroughly the patient's occupation when opticians make near vision prescription for initial presbyopia. 목적: 40대 초기 노안을 대상으로 작업환경이 다른 직업(운전자, 사무직, 주부, 현장직, 교사)에 따른 조절력의 변 화양상을 비교하고자 하였다. 방법: "푸쉬업(Push-up)" 방법과 "마이너스렌즈 부가"법을 이용하여 검사하고 직업별 평균 조절력(OD, OS, OU)을 비교하였다. 결과: 사무직(3.27±0.21D, 3.31±0.22D, 3.54±0.28D)이 우안, 좌안, 양안 모두에서 평균조절력이 가장 낮게 측정이 되었고, 주부(4.07±0.35D, 4.11±0.35D, 4.37±0.39D)가 우안, 좌안, 양안 모두 높게 측정이 되었다. 결론: 직업과 그에 따른 주시습관에 따라 눈의 조절력이 달라진다는 사실을 숙지하고, 노 안 검사 시 피검자의 직업에 대한 사항을 고려하여야 한다.

뒤십자인대 및 뒤가쪽 복합체 동반 수술 후 재활운동에 따른 기능회복 차이
김현목,하성희,공두환,김창국 한국융합학회 2022 한국융합학회논문지 Vol.13 No.3
This study aimed to compare functional recovery after rehabilitation exercise between isolated PCL reconstruction and combined PLC reconstruction. Patients were divided into two groups: those who had isolated PCL reconstruction (n = 16) and those who had combined PLC reconstruction (n = 16). We assessed knee joint ligament laxity, subjective questionnaires, and isokinetic muscle function before, after 12, and 24 weeks of a rehabilitation exercise program. In both groups, there were significant differences in knee joint laxity (p = 0.048), IKDC subject score (p < 0.001), Lysholm score (p < 0.001), Tegner score (p = 0.027), and isokinetic muscle deficit (p = 0.040) by estimated period. However, no significant difference between groups was observed (p > 0.05). These results suggest that rehabilitation exercise after isolated PCL and combined PLC reconstruction influenced structural, subjective, functional recovery positively. 본 연구는 뒤십자인대 단독 재건술과 뒤가쪽 복합체 동반 수술 후 재활운동에 따른 기능회복의 차이를 확인하는데 목적이 있다. 뒤십자인대 단독 재건술을 받은 환자 16명과 뒤가쪽 복합체 동반 수술을 받은 환자 16명을 대상으로 24주간 재활운동에 따른 무릎관절 인대 이완, 주관적 설문지, 등속성 근 기능의 변화를 수술 전, 수술 후 12주, 24주에 걸쳐 자료를 분석하였다. 본 연구 결과 뒤십자인대 단독 재건술군과 뒤가쪽 복합체 동반 수술군의 무릎관절 인대 이완 차이(p = 0.048), IKDC 주관적 점수(p < 0.001), Lysholm 무릎 점수(p < 0.001), Tegner 활동 점수(p = 0.027), 등속성 폄 근력(p = 0.040)은 기간에 따른 통계적 차이가 나타났으나 집단 및 상호작용 효과는 관찰되지 않았다(p > 0.05). 등속성 굽힘 근력 결손률은 기간, 집단, 상호작용 효과 모두 차이가 없었다(p > 0.05). 본 연구 결과, 뒤십자인대 단독 재건술과 뒤가쪽 복합체 동반 수술 후 24주간의 재활운동은 기능회복에 영향을 미칠 수 있다.

시합 시즌 중 단주기 저강도 회복 운동 프로그램이 운동 유발성 근육 손상이 있는 엘리트 축구 선수들의 근육 조직 손상 생체지표에 미치는 영향
김현목,서현,김창국 한국발육발달학회 2024 한국발육발달학회지 Vol.32 No.2
The purpose of this study was to verify whether a low intensity recovery exercise program during a 7-day micro cycle during the competition season does not negatively affect biomarkers of muscle tissue damage in elite soccer players with EIMD. In addition, the purpose is to determine at what stage during the recovery process EIMD biomarkers recover and whether athletic performance improves due to the supercompensation effect through the taper. Methods: This study was conducted from January 2023 to October 2023 on elite male soccer players belonging to Team A located in Songpa-gu, Seoul. A total of 16 people were selected and divided into 8 low intensity jogging group (LIJ) and 8 control group (CON). Blood tests were measured 11 times to check CPK and LDH levels, which are biomarkers of muscle tissue damage. To statistically analyze the measured results, GraphPad Prism 9.4.2. was used. [Results] There was no statistically significant difference in the change in CPK after EIMD between the LIJ and CON (p>0.05). There was also no statistically significant difference in changes in LDH between the two groups (p>0.05). Repeated measurements and post hoc verification results showed that CPK significantly increased on the 5th day (24 hours post-mortem) compared to the baseline. [Conclusion] This study confirmed that a 7-day micro cycle low intensity recovery exercise program during the competitive season did not cause additional muscle tissue damage in elite soccer players with EIMD. In addition, since it was confirmed that the supercompensation effect targeted through the taper strategy was normally achieved, low intensity jogging exercise can be organized as a regular recovery exercise program that can be performed without fear of additional muscle damage for individual or team goals. It is strongly recommended to players, coaches, and trainers.

직업에 따른 초기 노안의 상대조절력, 조절용이성, 가입도 비교
김현목,손정식,이원진,이재윤,조현국 한국안광학회 2009 한국안광학회지 Vol.14 No.4
Purpose: This study was designed to compare the relative accommodation, the accommodative facility, and the addition whose 40's initial presbyopia divided into five occupations (driver, official worker, housewife, field worker, teacher). Methods: We measured the values of near point convergence (NPC), positive relative accommodation (PRA), negative relative accommodation (NRA), accommodative facility, and addition. Results: Official worker group had lower PRA, higher NRA, and lower accommodative facility compared with them of the other groups. The average of addition was as follows: official worker>driver>field worker>housewife> teacher. Conclusions: Because the difference of working environment based on occupation affects the accommodative functions and addition, it is important to consider the patient's occupation when opticians measure the addition for near vision of initial presbyopia. 목적: 40대 초기 노안을 대상으로 직업군(운전자, 사무직, 주부, 현장직, 교사)에 따른 상대조절력, 조절용이성, 가 입도 값을 상호 비교하였다. 방법: 폭주근점 검사, 양성상대조절력 검사, 음성상대조절력 검사, 조절용이성 검사, 그 리고 가입도 검사를 실시하였다. 결과: 사무직이 다른 직업과 비교하여 낮은 조절용이성, 높은 음성상대조절력, 낮 은 양성상대조절력 값을 보였다. 가입도 측정값은 사무직>운전자>현장직>주부>교사의 순으로 나타났다. 결론: 직업에 따른 작업환경의 차이는 눈의 조절기능과 가입도에 변화를 줄 수 있음을 숙지하고, 초기 노안의 근용안경 처방 시 직업에 대한 사항이 충분히 고려되어야 할 것이다.
