본 연구는 절화 도·소매업자의 판매 행태, 소비자의 소비 행태와 수입산 절화 및 국내산 절화 인식을 조사하여 국내산 절화 경쟁력 강화를 위한 자료로 제공하고자 수행하였다. 설 문 조사는 도·소매업자 102명을 대상으로 2020년 7월부터 9 월까지 진행하였고, 소비자는 200명을 대상으로 2020년 8월 24일부터 25일까지 진행하였으며, 수집된 자료는 빈도 분석, 대응표본 t-test, 다중반응 교차분석을 실시하였다. 도·소매업 자의 판매 행태 조사 결과, 국내산과 수입산 절화 모두 판매하 고 있는 비율이 높았고 판매 시 국내산 절화의 품질보다 수입 산 절화의 품질이 우수하다고 응답하였다. 소비자의 구매 행 태 조사 결과, 주로 선물 목적으로 구매하며 구매 시 내적 품 질(수명)과 외적 품질(형태, 질감, 색상)을 중요시 여기는 것으 로 나타났다. 또한 소비자는 절화 구입 시 원산지를 확인하지 않는 경우가 많았으나 동일 품종일 경우 국내산을 구매한다고 응답하였다. 도·소매업자와 소비자의 절화 인식을 비교한 결 과, 도·소매업자는 국내산 절화가 평범하고 한정적이며, 수입 산 절화는 독특하다고 인식하였으나, 소비자는 국내산 절화가 독특하지만 수입산 절화와 국내산 절화 모두에 평범하고 한정 적이라고 인식하였다. 이러한 판매자와 소비자간 인식 차이는 실제 국가별 절화 품질에 대한 정량적 연구와 국가별 절화에 대한 인식 조사 필요성을 제기한다.

The purpose of this study was to investigate the short-term effects of lumbar rotational mobilization under the single-leg standing (SLS) position. Fifteen healthy individuals were recruited, and randomized to agroup of trunk rotational exercise (TRE) and lumbar rotational mobilization (LRM). Trunk twist rotational exercise was performed to the TRE group, and mobilization was applied to the LRM group on the lumbar spine. Velocity of the center of pressure (VCOP) and center of pressure (COP) for each participant were measured through SLS. COPs were not significantly increased or decreased after treatment in both groups. VCOPs also did not change considerably except on the right side when the eye was closed. There was no significant difference between COPs and VCOPs in two groups. This study suggests that trunk rotation exercise and lumbar rotation mobilization would have similar effects on balance ability.

The original focus of this study was to investigate the immediate effects of lumbar rotational mobilization on the one-legged standing ability. Fifteen subjects (6 men and 9 women, mean age = 22.77 (SD = 1.21), mean height = 165.46cm (SD = 11.65), mean weight = 61.46kg (SD = 8.29) volunteers from healthy individuals were recruited and randomized to a lumbar rotational mobilization (LRM) group and a trunk rotational exercise (TRE) group. Mobilization (grade 3 or 4) was applied to the LRM group on the lumbar spine (L1 to L5) in a side-lying, and trunk twist exercise (left and right side) was applied the to the TRE group with lunge position. Center of pressure (COP) and the velocity of the center of pressure (VCOP) of each participant were measured as a balance ability through one leg standing position. Results are as follows. In within-group difference, the COP of the LRM group reduced during standing with the right foot, but the VCOP change of the LRM was not statistically significant. In between-groups difference, COP of TRE group was decreased compared with LRM group only during left leg standing in the eyes (p <.05). The results of this study suggest that LRM is more effective than TRE in improving balance ability.

The main focus of this study was to investigate effects of lumbar central posteroanterior (PA) mobilization on isometric knee extension (IKE) ability and patellar tendon reflex amplitude (PTRA) in healthy university students. University students aged 19-26 (male; 10, female; 10) without any neurological disorders participated voluntarily and excluded the subjects with abnormal reflexes. The participation had an average body mass of 64.25±13.52 kg, an average height of 1.66±0.08m, and an average Body Mass Index (BMI) of 23.07±3.21. Every student was randomly assigned to be received squatting exercise and PA mobilization sequentially with 5 days of wash out period. IKE and PTRA were not significantly different between the two groups after the intervention. All the outcome measures were arranged into two data groups; PA mobilization and squatting exercise data group. In the PA mobilization data group, IKE and PTRA significantly increased after the intervention, however, these aspects were decreased in the squatting exercise group. These findings suggest that IKE and PTRA increase immediately after PA mobilization, therefore PA mobilization could be a valuable topic for controlled clinical trials.

The purpose of this study was to measure the mean peak mobilization forces to the lumbar spine 1-3 with grade III and grade IV of posteroanterior (PA) mobilization. Twenty subjects with no history of Lumbar back pain (LBP) (10 female, 10 male) with a mean age of 24.1 years (SD = 6.0) were recruited for the study and PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. In the results, applied grade IV force showed no different according to each segment in LS1, LS2, LS3, however, there are distinct differences between LS1 and LS2, LS1 and LS3 during mobilization with grade III force. This study suggested that the mean peak force of the grade III and grade IV mobilization in the L1-L3 was almost similar each other.
