This research was examined the effect of Backward Walk on ground reaction force and we achieved it by using ground reaction force machine during the Backward Walk activity with Latin and Rumba dance. We find that it was significant difference of vertical(Fz) ground reaction force of right foot in touchdown and toe-off and vertical(Fz), horizontal(Fx), front-rear(Fy) ground reaction force of left foot. There was not significant differences in vertical ground reaction force between superior athlete and unskilled athlete, but there was a significant difference in left foot. Through this, we know that the sports capability of left foot which has been developed through the training is better in superior athlete group. Therefore understanding of difference in ground reaction force and repeated training can help the unskilled athlete and beginner to accomplish the accurate movement.

Objectives: This study was designed to investigate the correlation between cervical, lumbar lordosis and low back pain(LBP), sex, age and duration of LBP. Methods : Cervical, lumbar lordosis(by Cobb's Method) and Ferguson's angle were measured and evaluated in LBP group and control. Radiograph was taken in lateral direction, erect position. Cobb's angle between C1-C7, C2-C7, L1-L5, L1-S1 and Ferguson's angle were measured and investigated with statistical program. Results: 1. Cervical lordosis have no relation to LBP, sex and age. 2. Lumbar lordosis and Ferguson's angle have no relation to LBP and sex. 3. Cobb's angle L1-L5 have no relation to age. Lumbar lordosis from L1 to S1(Cobb's angle L1-S1) increased in old group(Age>40) compared to young group(Age${\leq}$40). 4. In LBP group, Cobb's angle L1-S1 have no relation to duration of LBP. Lumbar lordosis from L1 to L5(Cobb's angle L1-L5) decreased in acute LBP group compared to Chronic group. Conclusions : Cervical, lumbar lordosis and Ferguson's angle have no relation to LBP and sex. As far as age is concerned, old group have larger lumbosacral lordosis than young group. Acute LBP group have smaller lumbar lordosis(Cobb's angle L1-L5) than chronic group.

Carcinoma ex pleomorphic adenoma(CXPA) is a rare malignant tumor of the salivary gland, fine needle aspiration cytology(FNAC) of which are rarely reported. We retrospectively reviewed FNAC of five cases of histologically proven CXPA of the salivary glands diagnosed in Seoul National University Hospital to evaluate their cytologic characteristics. Histologically, the carcinoma components were low-grade in three cases and high-grade in two cases. The cytologic diagnosis were malignancy in two cases(40%), suspicious for malignancy in one(20%), and benign(pleomorphic adenoma) in two(40%). All of the high-grade carcinomas were correctly diagnosed by FNAC, however, 2 cases of low-grade carcinomas were diagnosed as benign by FNAC. The low sensitivity in cytologic diagnosis is due to interpretative difficulties in low-grade tumors. The characteristic cytologic features of CXPA were high cellularity, necrotic, bloody, and inflammatory background, marked nuclear overlapping, coarsely granular chromatin, prominent macronucleoli, and atypical mitosis in epithelial component in addition to the typical biphasic pattern of pleomorphic adenoma consisting of epithelial cells admired with spindle-shaped cells and chondromyxoid stroma. Even though low-grade tumors show mild pleomorphism, the cytologic findings of necrotic background, moderate to high cellularity, and nuclear overlapping could lead to an accurate cytodiagnosis of CXPA.

We compared the diagnostic accuracy of liquid-based cervicovaginal cytology using $MonoPrep2^{TM}$ system (Monogen, Herndon, Virginia, USA), a manual system based on membrane filtration method, with conventional Pap smear. Study population included 92 patients visiting the gynecologic department under the suspicion of uterine cervical disease. In thirty of them, surgical biopsy was performed. $MonoPrep2^{TM}$ system provided well-preserved monolayer specimen with good nuclear morphology. However, about 19% of specimens were inadequate to interpret due to low cellularity. The detection rate of abnormal cells more than ASCUS (atypical squamous cells of unknown significance) was 23.9% and higher than 19.4 % of conventional Pap smear. Diagnostic concordance rate with conventional Pap smear was 81%, and severe discordance rate influencing on the management of patient was 7.6 %. Among these seven cases, $MonoPrep2^{TM}$ system was more diagnostic only in four. In comparison with histology, the sensitivity of diagnosis of $MonoPrep2^{TM}$ system was 78.9% and slightly higher than 73.5% of conventional Pap smear. However, the specificity was 81.1% and lower than 90.9% of Pap smear. In conclusion, $MonoPrep2^{TM}$ system provided diagnostic accuracies similar to the conventional Pap smear. The inexpertness of slide preparation and the low cellularity were considered to endow a limitation in more accurate evaluation.

The Information System(IS) planning for construction project management must be performed through decomposing the construction management business process upon considering the information technology in a construction company. Following this background, this paper proposes a model for evaluating the expected value of IS planning for construction project management. The model is made to analyze the effectiveness and to evaluate the opportunity of IS planning for task and information, then finally to quantify the value. Lastly, this model can be used to plan IS for construction project management.

Objectives: The purpose of this scoping review is to describe the research trends of postpartum healthcare for postpartum women, as well as to identify further direction for research in the area of postpartum healthcare. Methods: This study was conducted sequentially according to the Scoping Review Method referred to as 'frameworks of Arskey and O'Malley'. We searched for articles published as of May 15th, 2020 in seven Korean databases in order to obtain the data. A key term search strategy was employed, including terms such as "Postpartum period care", "Postpartum health", "Postpartum care", and "Postpartum status" to identify relevant studies. Results: Eighty-three articles were selected from a total of 259. The research has been undertaken steadily since 1997, particularly in the fields of Nursing and Korean medicine. In terms of study design, survey studies were the majority (48.2%), followed by interventions and experimental papers (32.5%). However, qualitative research areas are lacking. The research topics were largely divided into two categories: postpartum care characteristics and postpartum care interventions. The characteristics of postpartum care were highly connected with care for mental health. Among the postpartum care interventions, the most common employed was Korean medicine intervention. Conclusion: This study confirms that management of mental health during the postpartum period is necessary. In addition, it is necessary to identify the experiences of postpartum women and the effectiveness of a postpartum care intervention program through the utilization of qualitative research methods. In particular, such research is needed in the field of Korean medicine.

Objectives : We investigate the characteristics of foot reflex zone acupoint of facial paralysis patients. Methods : In order to make a comparison between facial nerve paralysis patient group and non-facial paralysis group, we measured foot reflex zone acupoint detection in both group of 18 patients who were diagnosticated to facial nerve paralysis and 18 persons who were not. Results : 1. In comparing the means of the foot reflex zone, the measurements of facial nerve paralysis group is different significantly from non-facial paralysis group(p<0.05). 2. The measurement of detection of foot reflex zone acupoints, such as hypophysis(垂體), nose(鼻), cerebrum(大腦), neck(頸項), Trapezius muscle(僧帽筋), eye(眼) and ear(耳) of the facial nerve paralysis group is different significantly in comparison with non-facial paralysis group(p<0.05). But the measurement of detection of foot reflex zone acupoints, such as trigeminal nerve(三叉神經), cerebellum (小腦), kidney(腎), ureter(輸尿管) and urinary bladder(膀胱) of the facial nerve paralysis group is not defferent significantly in comparison with non-facial paralysis group(p>0.05). Conclusions : The results suggest that foot reflex zone can be used in the diagnosis and treatment of facial nerve paralysis.
